This article provides a theoretical policy-making model of chemical sunset that gradually substitutes green alternatives for persistent toxic substances within a finite timeframe. The technological inflexibility of these substances is a tough obstacle to a chemical sunset, because a chemical sunset seeks to ultimately stop, within a short period of time, the risky businesses of these substances that are highly entrenched into our society. In wrestling with this obstacle, the intelligent precautionary “polluter pays” principle integrates three policy tools: a “precautionary (...) `polluter pays' principle,” “intelligent trial and error,” and democratic “regulatory negotiation.” It is designed to promote technological pluralism and strong democracy, as well as to create either trust or mutual adjustment among relevant groups.

This study explores the history of nanotechnology from the perspective of protein engineering, which differs from the history of nanotechnology that has arisen from mechanical and materials engineering; it also demonstrates points of convergence between the two. Focusing on directed evolution—an experimental system of molecular biomimetics that mimics nature as an inspiration for material design—this study follows the emergence of an evolutionary experimental system from the 1960s to the present, by detailing the material culture, practices, and techniques involved. Directed evolution, (...) as an aspect of nanobiotechnology, is also distinct from the dominant biotechnologies of the 20th century. The experimental systems of directed evolution produce new ways of thinking about molecular diversity that could affect concepts concerning both biology and life. (shrink)

ObjectivesHostile attribution bias is reportedly common from non-clinical population to those with serious mental illness, such as schizophrenia, and is known to be closely related to theory of mind. This study aimed to investigate whether ToM skills mediate the relationship among neurocognitive ability, personality traits, and attribution bias.MethodsA total of 198 non-clinical youths were recruited. To assess their neurocognitive ability and ToM skills, the participants were asked to complete Raven’s Standard Progressive Matrices and the Korean version of the Reading the (...) Mind in Eyes Test. To determine their personality traits, the Eysenck Personality Questionnaire and interpersonal reactivity index were used. To evaluate hostile attribution bias, the Ambiguous Intentions Hostility Questionnaire was administered. Path analysis and bias-corrected percentile bootstrap methods were used to estimate model fit and the parameters of the mediating effects.ResultsBased on model comparison, the best model characterized two direct pathways from psychoticism and the K-RMET to hostility attribution bias and three indirect pathways, wherein SPM, perspective taking, and psychoticism influenced hostile attribution bias through K-RMET. The final model fit indices were good [x2/df = 1.126; comparative fit index = 0.996; root mean square error of approximation = 0.026; standard root mean square residual = 0.026 and Akaike information criterion = 28.251] and the K-RMET fully mediated the association between SPM, perspective taking, psychoticism, and hostile attribution bias.ConclusionThe main findings suggested that ToM skills, such as the RMET, play an important role in explaining the relationship among neurocognitive ability, personality traits, and hostile attribution bias. ToM skills and a remediation strategy may need to be developed to balance the enhanced hostility bias that underlies the paranoia. (shrink)

This descriptive study was undertaken to identify the degree of ethical sensitivity of staff nurses and to analyze the differences in ethical sensitivity in terms of both general and ethics-related characteristics. Participants were 236 staff nurses working in general hospitals in Korea. Ethical sensitivity was measured by means of an instrument developed by the researchers. The results showed that the mean score for the degree of ethical sensitivity was 0.71 out of a possible maximum score of 1 (range 0.30 to (...) 0.97). For general characteristics, there was a significant difference in ethical sensitivity according to age (F (df 2233)-3.99, P-0.02). For characteristics related to ethics, there was a significant difference in ethical sensitivity according to attitude towards the nursing profession (F (df 4231)-2.94, P-0.03). It is therefore recommended that a training program reflecting these variables be developed to enhance staff nurses’ ethical sensitivity. (shrink)

This longitudinal study examined the development of moral judgement in 37 nursing students attending a university in Suwon, Korea. The participants completed the Korean version of the Defining Issues Test to allow analysis of their level of moral judgement. The development of moral judgement was quantified using ‘the moral development score’ at each stage (i.e. the six stages detailed by Kohlberg) and the ‘P(%) score’ (a measure of the overall moral judgement level). The results were as follows: (1) the moral (...) development score for stage 5A was consistently the highest across the four years of the students’ course, showing significant differences in some sociodemographic factors including home, birth order and monthly income; and (2) the P(%) score was higher in fourth-year (47.47 ± 11.21) than in first-year (46.13±9.73) students. There was no significant difference in the P(%) score according to sociodemographic factors. Further studies will examine in detail the correlation between curriculum and moral judgement development. We suggest that courses in ethics education should be made more relevant. (shrink)

Background Nurses providing care to patients with end-of-life or terminal illnesses often encounter ethically challenging situations leading to moral distress. However, existing quantitative studies have examined moral distress using instruments that address general clinical situations rather than those specific to end-of-life care. Furthermore, qualitative studies have often been limited to participants from a single unit or those experiencing moral distress-induced circumstances. A comprehensive and integrated understanding of the overarching process of moral distress is vital to discern the unique circumstances surrounding (...) end-of-life care and its consequential impacts. Research objectives To explore the moral distress experiences of nurses who are frequently involved in caring for patients with end-of-life or terminal illnesses and apply it to two existing theories: the model of moral distress and the ecological model. Research design A qualitative descriptive approach was employed. Participants and research context Seven focus group interviews involving 30 nurses were performed. The subsequent transcriptions underwent rigorous content analysis. Ethical considerations We obtained Institutional Review Board approval from a university. Focus group interviews were conducted with nurses who agreed to participate and signed the consent form. Findings The moral distress-inducing factors and nurses’ perceived impact of moral distress were identified and categorized based on moral distress theories and ecological models. A total of 15 categories and 30 subcategories across the following 4 domains were derived: (1) intrapersonal, (2) interpersonal, (3) organizational, and (4) structural factors. Conclusions End-of-life-specific circumstances induced moral distress among nurses, with both negative and positive impacts identified. Effective organizational and policy support is essential to manage conflicts, form a healthy organizational culture, provide training, and prevent unnecessary expenses due to the negative consequences of moral distress.

Temporal Changes in Ovarian Gonadotropin-Releasing Hormone mRNA Levels by Gonadotropins in the Rat Sung Ho Lee, Eun-Seob Song, Sun Kyeong Yu, Changmee Kim, Dae Kee Lee, Wan Sung Choi l and Kyungjin Kim* Department of Molecular Biofogy and SRC for Cell Differentiation, Seoul National University, Seoul 150-742, Korea; IDepartment of Anatomy, College of Medicine, Gyeongsanf; National University, Chinju 660-280, Korea (Recei·. cd on December 29, 1993) The present study examines whether gonadotropins are involved in the regulation of ovarian (...) GnRH gene expression and how ovarian GnRH gene expression temporalJy correlates with alterations in hypothalamic GnRH, pituitary LH~ gene expression in respons to gonadotropins. Hypothalamic and ovarian GnRH mRNA and pituitary LH~ mRNA levels were determined by respective RNA-blot hybridizations, and ovarian GnRH and estradiol contents and serum LH levels were measured by respective radioimmunoassays. Three animal models such as 1) PMSG-treated, 2) PMSG and heG-treated immature rats and 3) proestrous stage of adult rats were used. Immature rats (25-days old) were administered with PMSG (10 iu) at 10:00 hand 48 h later with heG (10 iu) to induce ovulation. In the PMSG-injected model, hypothalamic GnRH mRNA levels were markedly augmented about 9-fold at 50 h, and pituitary LH mRNA 3-fold at 52 h after PMSG administration. Serum LH levels were increased to the preovulatory surge levels at 56 h, and ovarian GnRH mRNA levels were augmented 4-fold at 60 h after PMSG injection. Administration of heG also induced a marked enhancement in ovarian GnRH mRNA levels in comparison to the values shown in both intact and PMSGtreated rats at 52 hand 54 h, respectively. In the proestrous stage of normal adult rats, pituitary LH~ mRNA levels were peaked at 16:00 h. The preovulatory LH surge was evident at 4 h before increment in ovarian GnRH mRNA levels as shown in PMSG-treated rats. The present study clearly showed the sequential increase in hypothalamic GnRH mRNA, pituitary LH~ mRNA and ovarian GnRH mRNA levels, indicating that ovarian GnRH may play a possible role in the control of follicular maturation and the ovulation process.

The purpose of this paper is to explore the concepts of issue legitimacy and organizational legitimacy, providing a new measure of each construct. The scales were developed and tested using data collected through a statewide survey of Alabama residents. Assessments of issue legitimacy were based on perceptions of direct-to-consumer advertising, whereas assessments of organizational legitimacy were based on perceptions of the pharmaceutical industry as a whole. The findings provide evidence that organizational legitimacy can be reliably measured using a five-item scale (...) and issue legitimacy can be reliably measured using a six-item scale. The implications of the results and potential uses of the scales are discussed. (shrink)

We examined nurses’ perceptions of the ethical climate of their workplace and the relationships among the perceptions, medical error experience and intent to leave through a cross-sectional survey of 1826 nurses in 33 Korean public hospitals. Ethical climate was measured using the Hospital Ethical Climate Survey. Although the sampled nurses perceived their workplace ethical climate positively, 19% reported making at least one medical error during the previous year, and 25% intended to leave their jobs in the near future. Controlling for (...) individual and organizational characteristics, we found that nurses with a more positive perception of the ‘patient’ dimension of ethical climate were less likely to have made medical errors. Nurses with a more positive perception of the ‘patient’, ‘manager’, ‘hospital’ and ‘physician’ dimensions of ethical climate were less likely to leave their current job. Enhancing workplace ethical climate could reduce medical errors and improve nurses’ retention in public hospitals. (shrink)

With the advancement of medical technology, various life-sustaining treatments are available at the end of life. Older adults should be encouraged to establish their end-of-life treatment preferences (ELTP) while they are physically and mentally able to do so. The purpose of this study was to explore ELTP among older adults and to compare those preferences in a subset of individuals who had reported their ELTP in a survey completed the previous year. This was a descriptive study of 191 older adults (...) living in a continuing care retirement community. Approximately half of the participants did not want cardiopulmonary resuscitation, to be put on a respirator, or to receive dialysis. The findings in this study suggest that many older adults do not want aggressive interventions at the end of life, but choose rather those measures that will keep them comfortable. Moreover, treatment choices may change over time. Health care providers should initiate discussions about ELTP at regular intervals (yearly) to assist older adults in dictating their end-of-life care. (shrink)

The zone of proximal development (ZPD) is defined as an overarching concept that integrates the main tenets of Vygotsky’s theory of human development. The conceptualization of the ZPD begins with its social, cultural, and historical context and traces its development as a spatial and temporal metaphor that reflects the sociogenetic root of all human mental functioning. Beyond the explication of sociogenesis, the ZPD is reconceptualized to include the notions of voice and dialogicality. The insights gained from the fields of semiotics (...) and discourse studies allow a broader understanding of the ZPD by bringing to light participant structures and institutional and historical forces that may not have been included in the dominant interpretations of the ZPD.

Science museums aim to provide educational experiences for both children and adults. To achieve this goal, museum displays must convey scientifically-relevant relationships, such as the similarities that unite members of a natural category, and the connections between scientific models and observable objects and events. In this paper, we explore how research on comparison could be leveraged to support learning about such relationships. We describe how museum displays could promote educationally-relevant comparisons involving natural specimens and scientific models. We also discuss how (...) these comparisons could be supported through the design of a display—in particular, by using similarity, space, and language to facilitate relational thinking for children and their adult companions. Such supports may be pivotal given the informal nature of learning in museums. (shrink)

Cet article s’attache à décrire l’évolution dans l’amitié entre Chŏng Yakyong et Yi Kigyŏng. Beaucoup de choses les rapprochaient, objectivement. Tous deux étaient de brillants lauréats du concours du doctorat de 1789, tous deux étaient membres de la même faction politique, les Namin (les ''Sudistes''), tous deux étaient fonctionnaires civils à la cour du roi Chŏngjo ( r. 1776-1800) dans la Corée de l'ère Chosŏn (1392-1897), et tous deux jouèrent un rôle important dans cette période de grands changements, à la (...) fois socio-politiques, religieux, culturels et intellectuels, que vécut alors la Corée. Chŏng Yakyong s’intéressa à de nombreuses branches différentes du savoir occidental qui parvenait alors à la Corée, et il embrassa même, brièvement après sa confession, la foi chrétienne en 1784. Se sentant critiqué et calomnié, il la renia publiquement en 1797, mais son ami Yi Kigyŏng, auteur du Pyŏgwip’yŏn 闢衛編 ( Compilation de documents pour le rejet de l’hétérodoxie et la défense de l’orthodoxie ), ne voulut jamais y croire. Cet ami devint même un ennemi au point qu’il l’attaqua violemment, en 1801, ce qui valut à Chong Yakyong un long et douloureux bannissement jusqu’en 1818. À travers la lecture des textes dont nous disposons, officiels et personnels, nous tentons de comprendre ce qui s'est joué alors et d'analyser l’évolution de leur amitié face à ce qui les divisa – ces événements qui furent tragiques pour beaucoup de monde.

This article attempts to fill a gap in International Relations literature on East Asian security. ‘East Asia’ appears to be mostly an indeterminate conceptual construct, allowing scholars to look selectively at those aspects and areas that could justify their security thesis, albeit security dynamics in the region are all too difficult to comprehend and predict. This problem has been frequently pointed out in IR literature, but its methodological implications and suggestions have neither been appropriately illuminated nor been systematically offered, and (...) the main solution commonly found in the literature was the tautological one of ‘better defining’ the region. As an alternative, this article suggests that one needs to tighten geographical focus and differentiate the subjects of analysis. When it comes to the study of East Asian security, one needs to aim to develop specific and differentiated generalizations as opposed to generalizations of a broad character. To showcase the fact that research outcomes can be more determinate when the target of analysis is more focused and specified, this article takes Northeast Asian security as an example and challenges the so-called ‘peaceful East Asia’ thesis, one of the mainstream perspectives on East Asian security. This article ultimately argues that while apprehending East Asian security dynamics through delimiting the scope of analysis and circumscribing the subjects of investigation is often deemed to be a modest enterprise―in particular, in terms of generalizability―the merits are substantial: research outcomes will be able not only to give us a truer mapping of the real world, but also bring us closer to building knowledge which satisfies the scientific criterion of ‘falsifiability.’Export citation Request permission.

In contrast to the juxtaposition of representative democracy and Confucian meritocracy that is currently being discussed in international political theory, we start from the hypothesis of a historical, intercultural and logical, simultaneous provenance of democracy and meritocracy in the evolution of the modern constitutional state. To this end, we examine the reception of Confucianism in the republican history of ideas of European Enlightenment using selected examples ranging from Leibniz to the classical constitutional and government theory of Sieyès. The widespread ignorance (...) of the Confucian elements in the classical core of modern republicanism that we have evaluated here is attributed to the needs of political legitimacy and the methodical ahistorism and historical amnesia of academic discourse.

This paper examines the friendship between Chŏng Yakyong and Yi Kigyŏng and its evolution. Their friendship rested on many commonalities: they both passed the doctorate competition together successfully in 1789, they belonged to the same political faction, the Namin, they were both officials at the court of King Chŏngjo in Chosŏn Korea, and both had important roles and contributions in this period of great socio-political, religious, cultural, and intellectual transformations. Being interested in different areas of knowedge from the West that (...) had reached Chosŏn Korea, Chŏng Yakyong, or Tasan, adopted the Christian faith in 1784 before publicly renouncing it in 1797 due to criticism and slander. His friend Yi Kigyŏng, however, did not believe his apostasy and became his enemy. By studying the official and personal documents available, we attempt to reconstruct the vicissitudes of their friendship that resulted in Tasan’s long and painful banishment. (shrink)

Mechanism is a conception of the world according to which all can be explained by mechanics expressed by its fundamental concepts and principles. I’ll firstly show that, following Poincaré’s discussion on mechanical explanation, the very foundation of classical mechanics implicates that all just can’t be explained. Next, I’ll discuss the principles of mechanics as they are viewed by Poincaré, especially the principle of relativity that has a particularity in its form of “pseudo-universal”argument, as well as in its fundamental role for (...) experiences. It will be finally revealed that, the mechanism can be used as a convention, because, by the principle of relativity, we can have only local experiments but never on the universe, and consequently, non of our experiences would never lead us to any phenomenon irreducible to mechanics. Nevertheless, it doesn’t exclude the contrary possibility: experiences can reveal that it is not to commode as it used to be, without disapproving it. (shrink)

In empiricism, there are only two answers for a question: black or white. Yet, subjective meanings of human behaviours and responses toward health and illness cannot be simply explained with black and white. Gray zones are needed because they are characterized by complexity and require a contextual understanding. In this paper, we present and suggest fuzzy logic as an example of theoretical bases that help transcend the conflicts between objectivity and subjectivity, respect gray zones between black and white answers for (...) questions, and provide a contextual understanding of complex nursing phenomenon. A historical review of fuzzy logic is followed by a definition of fuzzy logic. Then, fuzzy logic is discussed in terms of its compatibility with nursing epistemological views and philosophical thoughts. Fuzzy logic agrees with three categories of epistemological views of nursing, including correspondence, coherence and pragmatism. Fuzzy logic also agrees with four major philosophical thoughts in nursing, including postempiricism, pragmatism, feminism, and postmodernism. Based on the discussion, we propose that fuzzy logic be further explored, used and developed in research and practice in the nursing areas/situations/phenomena that are characterized by complexity, ambiguousness, and vagueness.

In the 1990s P.H. Hirst criticizes his influential forms of knowledge theory, suggesting a new concept of education. In this paper I explain why Hirst suggests the new concept of ‘education as initiation into practices’. Although the latter Hirst’s position had positive implications on education, it is frequently confused with theutilitarian position. In order to provide a more coherent concept of education, I compare basic features of the rationalist (R), the utilitarian (U), and the practices-based (P) approach. Then I discuss (...) the implications of this concept. The main features of R, U, and P are respectively as this: 1) A person is seen as a rational being, a being of wants and desires, and a rational practitioner who is socially constructed. 2) The nature of reason is conceived as ‘rational’,‘instrumental’, and ‘practical’. 3) The aim of education is education for theoretical rationality, education for maximum satisfaction of desires, and education for identity formation by participating in practices. 4) The contents of education are theoretical knowledge, instrumental knowledge with utility, and practical knowledge for various practices. 5) R pursues absolute transcendental values, U pursues extrinsic instrumental values, and P pursues values internal to a practice. 6) R conceives education as ‘seeing’, U as ‘doing’, and I suggest ‘listening’ model for P. Based on this conception of practices-based position, I hope we can provide better education. (shrink)
