We have made a survey of 40 patients in the university hospitals and oriental medical centers in Seoul from Sep. 1, 1997 to Mar. 1, 1998. We sampled 25 of them and the result shows that there were 12 MCA damaged patients(48%), 5 SAH(20%), 5 ACA(20%), 2 PCA (8%), 1 PCOA(4%). The number of MCA patients were the most. 1. As the cause of each disease, 4 of the 12 MCA damaged patients(33.35%) have infarction and cerebral hemorrhage, 2 of 5 SAH patients(40%) have cerebral hemorrhage and head injury, 3 ACA damaged patients have cerebral hemorrhage. 11 of 25 brain bloodvessel damaged patients(44%) were hemorrhage patients. 2. Rt. hemiparesis was the main symptom of 6 of 12 MCA damaged patients(50%) and 3 of 5 SAH patients(60%), and the main symptom of 3 of 5 ACA patients(60%) was Lt. hemiparesis. The main symptom of 13 of 25 brain bloodvessel damaged patients(52%) was Lt. hemiparesis 11 of them(44%) Rt. hemiparesis, and 1 of them(8.3%) Quadriplegia. 3. Language was the most well preserved function. 12 MCA damaged patients could understand language. 4. Retraction of shoulder girdle, among VIE flexor synergy, was the most frequent element because 9 of 12 MCA damaged patients had it. Among VIE flexor synergy, 5 SAH patient's most frequent synergy was Elbow flexion because all of them had it. All of 5 ACA damaged patients have shoulder girdle elevation, shoulder joint, hyperextension, abduction, and external rotation among VIE flexor synergy. 5. 7 of 12 MCA damaged patients(58.3%) were stereognosis handicapped patients, 3 of 5 SAH patients(60%) have handicap of position sense, light touch, and temperature, 3 of 5 ACA patients(60%) have position handicap. 13 of brain bloodvessel damaged patients(52%) have light touch handicap. 6. 8 of MCA damaged patients(66.7%) have facial palsy, 4 of SAH damaged patients(80%) have memory and action decline, and 3 of ACA damaged patients(60%) have action decline and facial palsy. The problem of Hemiplegia is very extensive from muscle weakness, atrophy, or deformation to psychical problems. Therefore physical therapists should have sufficient interest in psychological handicap as well as physical handicap as they deal with adult hemiplegia.

There have been many studies and experiments regarding exhibition lighting. Many experiments on photochemical damaging effect and visibility resulted in a practice limited to assigning light levels and adjusting annual exposure time. The three damaging factors to the artifacts are intrinsicsusceptibility to absorb radiant energy, spectral distribution of light source and intensity of illumination and time of exposure. Dividing all the artfacts into three categories to suggest a recommended illuminance level causes some problems. Blue wool, for example, used as the reference material for susceptibility, is not a standard material representing museum artifacts. In the most light sensitive category, ISO class I or anything below have been excluded. The exposure time of one soure can be three times more than another sourece. The spectral distribution of the light source and the relative spectral responsibility of the artifact are not considered in the practice. So in case of very light sensitive material, the recommended illuminance is only the referring value and it is indispensable to check the characteristic of susceptibility of each artifacts. Daylighting is prevailing method to solve the psychological need of the visitors. However, it sould transparent, and should not diffused, and the green-house effect must be considered. llluminance uniformity should based on the maximum illuminance to handle the limitation of exposure for the conservation of a large sensitive object such as a painting. Damage index is not absolute reference for selecting the lighting source because it is experimented from the paper of low grade then calculated. Visibility should be increased by reducing the visual noiseand by planning of appropriate luminance contrast. This paper reviews the problems with the previous studies and experiment sand the current exhibition lighting design practice. The plan for museum showcase lighting is to check the susceptibility and to raise the visibility simultaneously.

중추신경계는 일단 손상이 되면 손상된 세포의 재생, 손상된 수초의 회복, 신경계의 정상적인 연결 등의 제한성 때문에 그 회복이 매우 힘들다. 이러한 중추신경계의 중요한 손상으로는 다발성 경화증, 뇌졸중, 척수손상, 외상, 축삭의 탈수초화 등이 있다. 이전 연구들은 많은 발생빈도를 보이고 있는 척수손상에서 실질적인 척수의 기능적인 회복을 위해 손상된 척수신경의 재생과 축삭의 재수초화가 중요한 요인이라고 전하고 있다. 최근에는 이러한 척수손상에 대한 치료적 접근으로서 세포이식 기술이 하나의 해결책을 열어주고 있다. 따라서 본 논문에서는 척수손상의 특성을 살펴보고, 척수손상에 의한 기능장애에 대해 세포이식이 기능의 회복을 증진시킬 수 있다는 증거를 논의하고자 한다.

Background: Organizational ostracism is defined as a violation of norms that we are suggested to acknowledge at the workplace. It results in the exclusion of one person or multiple persons, and causes damage to our innate need to belong. This kind of behaviorism can be engaged through a hierarchical or nonhierarchical relationship. Three elements interact in the framework of organizational ostracism: the actor, the target, and the institution. Our aim was to describe the different factors interacting with every element in order to produce recommendations targeting to prevent the occurrence of such behaviorism in an institution and to help targets of such a violence in order to handle this situation and go forward. As psychological impact of ostracism has frequently been studied in the literature, we focused on its impact on professional tasks. Methods: We performed a questionnaire-based study about organizational ostracism. This questionnaire was established through an online platform (https://www.sondageonline.com) and made available through the following link: https://goo.gl/forms/KrkVXe3bMEc79cau2. A keyword was sent to all participants. We created a 23-interrogation questionnaire with open and short questions. Nonwritten consent was obtained from all participants. Results: The actor of ostracism engaged in ostracism, in most of the cases, with other persons without a real purpose. The actor of ostracism had an antecedent of problematic relationship at work in 82.9% of the cases. Of the participants, 58.5% were of the view that ostracism aimed to cause hurt and isolate them. Professional isolation was observed in 58.5% of the cases; 51.2% of the participants tried to improve their work potential and explained their reaction by an intrinsic motivation. The organization atmosphere was judged to be bad in most of the cases. Conclusion: Our study showed that ostracism was mainly observed in public practice.

Farnesol in fruits, vegetables, herbs and leaves acts as bioactive component related with prevention of cancer and psychological malaise. We investigated the cytotoxic effects of farnesol on human leukemic cell, HL-60 cells, by MTT assay using 3- (4,5-Oirnethylthiazol-2-yl) -2,5-diphenyltetrazoliumbromide. Farnesol (0.1${\sim}$50 ${\mu}$g/ml) exhibited cytotoxicities against HL-60 cells in concentration and culture period dependent manner, In the cytotoxic condition induced by farnesol against HL-60 cells, the generation of reactive oxygen species such as O$_2$ and H$_2$O$_2$ were found to be considerably increased. The most prominent augmentations of O$_2$ and H$_2$O$_2$ were over five folds of controls. In an attempt to explore the response of HL-60 cells to the increased O$_2$ and H$_2$O$_2$, superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase activities of HL-60 cells treated with farnesol were measured. SOD and GPx activities were found to be remarkably elevated by addition of farnesol showing the best results of 273% and 167% of controls, respectively: All data suggest that farnesol may have played as an apoptosis inducer in HL-60 cells via production of reactive oxygen species (ROS) and HL-60 cells may have failed to overcome the damage of ROS on account of still defcient ROS scavengers including SOD and GPx.

Purpose: The researchers reviewed the previous studies on the psychological anxiety and economic damage during the recent COVID-19 pandemic to understand the satisfaction, awareness and attitude of the residents in Jeju, Korea. Research design, data and methodology: 215 samples based on self-reported survey were collected for path analysis focused on controlling variables in demographic characteristics in PLS-SEM using Smart PLS 3.0. Results: The researchers found the Satisfaction with COVID-19 Prevention Measures and the Awareness of Tourism Crisis affect Attitude toward Tourism of the residents with the explanatory power (R² = 0.209). Age was found to be the only significant controlling variable in this model for the Awareness of Tourism Crisis to Attitude toward Tourism. Conclusions: The attitude toward tourism is influenced by the level of satisfaction of the prevention service for COVID-19 as well as the awareness of the crisis. Residents have different level of the tourism crisis awareness by the status of their economic activities while there is no differences in all age groups for satisfaction in the quarantine service. The study suggests that the importance of the public health service should be preferentially concerned for residents to have stable economic activities where the tourism is the major industry.
