본 논문에서는 도가 계열에 속하는 열자의 감정 수양론에서 제시하는 정서적 평정심과 행복에 이르는 방법에 대해 느낌과 인지의 측면에서 분석한다. 첫째, 열자의 감정 수양론은 인간 감정이 무위자연의 천기(天機) 혹은 자연의 이치와 조화를 이루어야 한다는 도가적 관점을 전제로 하여 전개된다. 천기와 이상적으로 감응해 정서적 평안 상태에 도달한 사람을 가리켜 지인, 진인, 신인이라고 부른다. 한편 천기에 어긋나는 유위적 요인들에 의해 정서적 혼란이 발생한다. 열자는 유위적 요인들을 제거하는 과정에서 무심(無心), 심허(心虛), 심재(心齋) 등과 같은 해체적인 방법을 사용한다. 둘째, 열자의 감응론은 감각기관이 외물에 얼마나 조화롭게 반응하는지에 (...) 따라 정서적 혼란과 안정 상태를 구별한다는 점에서 신체에서 활성화되는 느낌의 적절성을 중시한다. 천기는 귀, 눈, 코, 입, 피부 등과 같은 감각기관(所)을 감각기관이도록 만드는(所以) 발생론적 근원이라는 점에서 신체적 느낌의 적절성을 판별하는 기준 역할을 한다. 바꾸어 말하면 적절성을 얻지 못한 과불급 상태의 신체적 느낌은 자연의 이치에 상응하지 못함으로써 생겨난다. 셋째, 열자의 감정 수양론은 미혹된 인지(惑)가 정서적 혼란을 일으키는 주요 원인이므로 이를 해체해야 한다고 주장한다는 점에서 인지와 감정 간 긴밀한 연계성을 가정한다. 미혹된 인지란 어떤 사물이나 사태에 대한 잘못된 견해나 믿음을 가리킨다. 열자는 한편으로는 불필요한 인지에 대해 잊음(忘), 알지 못함(不知), 앎이 없음(無知) 등과 같은 해체적 메타 인지를 구성하고 다른 한편으로는 세계의 실질(實)과 자신의 운명(命)에 대해 제대로 통찰함으로써 정서적 안정을 얻고자 한다. 넷째, 열자는 참된 인지에 기초한 긍정적 감정의 실현을 통해 적극적으로 행복을 추구한다. ｢양주｣편을 중심으로 나타나는 쾌락주의적 행복론은 열자철학이 도가 계열에 속하면서도 장자나 노자의 사상과 구별되는 특성을 잘 보여준다.

This study investigated the usefulness of the six-item Stress and Anxiety to Viral Epidemics scale and the Coronavirus Anxiety Scale as tools to assess anxiety related to coronavirus disease in cancer patients. A total of 221 patients with cancer responded to an anonymous online questionnaire between 15 July and 15 August 2020. The functional impairment of the patients was assessed using the Work and Social Adjustment Scale, and the SAVE-6 and CAS were also applied. Among these 221 cancer patients, 110 (...) had SAVE-6 scores ≥ 15 and 21 had CAS scores ≥ 5. Within the study population, 104 and 29 patients had WSAS scores ≥ 11 and ≥ 21, respectively. The correlations between the SAVE-6 and WSAS and CAS scores were statistically significant. The cut-off for the SAVE-6 was 15 points, while that for the WSAS was 11. Our results suggested that the SAVE-6 and CAS could be used to evaluate moderate and severe degrees of functional impairment related to mental health, respectively, in cancer patients during viral epidemics.

In a paper where we tried to show in how many different meanings the term is chiefly used in the philosophy of Aristotle, we discussed the relation between and , but neglected the relation between and , which seems to be yet more important. The neglect, however, was purposeful; for to answer the question what the latter relation is requires a special research. This we are now going to carry out.

Every student of Plato will be inclined to admit that, among his dialogues, the Parmenides is one of the hardest to understand. The attempt to elucidate it has continued since ancient times, but even to-day we still lack a definitive interpretation. The first part of the dialogue is relatively simple; it is with the second that the great difficulty begins. Two questions are raised: firstly, how this part is to be understood, and, secondly, how it is related to the first (...) part. (shrink)

SignificanceElectrical burns can cause severe damage to the nervous system, resulting in autonomic dysfunction with reduced cerebral perfusion. However, few studies have investigated these consequences.AimTo elucidate changes in prefrontal cerebral hemodynamics using functional near-infrared spectroscopy (fNIRS) during the head-up tilt table test (HUT) for patients with electrical burns.ApproachWe recruited 17 patients with acute electrical burns within 1 week after their accidents and 10 healthy volunteers. The NIRS parameters acquired using an fNIRS device attached to the forehead were analyzed in five (...) distinct HUT phases.ResultsBased on their HUT response patterns, patients with electrical burns were classified into the group with abnormal HUT results (APG, n = 4) or normal HUT results (NPG, n = 13) and compared with the healthy control (HC, n = 10) participants. We found trends in hemodynamic changes during the HUT that distinguished HC, NPG, and APG. Reduced cerebral perfusion and decreased blood oxygenation during the HUT were found in both the NPG and APG groups. Patients with electrical burns had autonomic dysfunction compared to the HC participants.ConclusionsUsing fNIRS, we observed that acute-stage electrical burn injuries could affect cerebral perfusion.

River water pollution by wastewater can cause significant negative impact on the aquatic sustainability. Hence, accurate modeling of this complicated system and its cost-effective treatment and reuse decision is very important because this optimization process is related to economic expenditure, societal health, and environmental deterioration. In order to optimize this complex system, we may consider three treatment or reuse options such as microscreening filtration, nitrification, and fertilization-oriented irrigation on top of two existing options such as settling and biological oxidation. The (...) objective of this environmental optimization is to minimize the economic expenditure of life cycle costs while satisfying the public health standard in terms of groundwater quality and the environmental standard in terms of river water quality. Particularly, this study improves existing optimization model by pinpointing the critical deficit location of dissolved oxygen sag curve by using analytic differentiation. Also, the proposed formulation considers more practical constraints such as maximal size of irrigation area and minimal amount of filtration treatment process. The results obtained by using an evolutionary algorithm, named a parameter-setting-free harmony search algorithm, show that the proposed model successfully finds optimal solutions while conveniently locating the critical deficit point.

Objects: To evaluate the feasibility and effectiveness of in-bed wearable elbow robot training for motor recovery in patients with early and late subacute stroke.Methods: Eleven in-patient stroke survivors received 15 sessions of training over about 4 weeks of hospital stay. During each hourly training, participants received passive stretching and active movement training with motivating games using a wearable elbow rehabilitation robot. Isometric maximum muscle strength of elbow flexors and extensors was evaluated using the robot at the beginning and end of (...) each training session. Clinical measures including Fugl-Meyer Assessment of upper extremity, Motricity Index for upper extremities, Modified Ashworth Scale were measured at baseline, after the 4-week training program, and at a 1-month follow-up. The muscle strength recovery curve over the training period was characterized as a logarithmic learning curve with three parameters.Results: At the baseline, participants had moderate to severe upper limb motor impairment {FMA-UE [median ]: 28 } and mild spasticity in elbow flexors {MAS [median ]: 0 }. After about 4 weeks of training, significant improvements were observed in FMA-UE and MI, and the improvements were sustained at the follow-up. The elbow flexors MVC significantly increased by 1.93 Nm and the elbow extensor MVC increased by 0.68 Nm. Muscle strength recovery curve showed that patients with severe upper limb motor impairment had a greater improvement rate in elbow flexor strength than those with moderate motor impairment.Conclusion: In-bed wearable elbow robotic rehabilitation is feasible and effective in improving biomechanical and clinical outcomes for early and late subacute stroke in-patients. Results from the pilot study suggested that patients with severe upper limb motor impairment may benefit more from the robot training compared to those with moderate impairment. (shrink)
