Background: Although deleterious effects of sunlight have been increased recently, the surveillance of the attitudes toward sun-exposure and the behavioral aspect of using sunscreens in Koreans has hot been carried out. Objective: Our purpose was to evaluate the attitude toward the harmfulness of sun-exposure and behaviors of using sunscreens in Korea. Method: Five hundred and fifty-two subjects were surveyed to assess the attitude toward sun-exposure, as well as the subjects knowledge about, and the use of sunscreens. Underlying data including demographic data, skin colors, skin types, occupation, and sun-exposure, were obtained. Results: Fifty-four percent of subjects believed that sun-exposure is bad for their skins, but, on the contrary, 12.5% believed it to be beneficial. Fifty-two percent of subjects used sunscreens. Almost all subjects(93.8%) knew why to use sunscreens but 62.7% of subjects did not know the meaning of sun protective factors(SPF). Women, indoor workers, subjects less than 40 years old, with less sun-exposed, fair colored skin, or with skin type I, II, III tended to know the deleterious effects of sunlight and the meaning of SPF and used more sunscreen. Conclusion: High risk population-men, outdoor workers, subjects oider than 40 years old, with more sun-exposed, dark colored skin, or skin type VI, V could be targeted with campaigns that promote attitudinal and behavioral changes.

The leaf beetle, Chrysolina aurichalcea (Coleoptera: Chysomelidae), is a pest damaging plants of Compositae. In order to understand the genetic diversity and geographic variation we sequenced a portion of mitochondrial COI gene (658 bp) and complete nuclear internal transcribed spacer 2 (ITS2) of the species collected from seven Korean localities. A total of 17 haplotypes (CACOI01~CACOI17), with the maximum sequence divergence of 3.04% (20 bp) were obtained from COI gene sequence, whereas 16 sequence types (ITS2CA01~ITS2CA16), with the maximum sequence divergence of 2.013% (9 bp) were obtained from ITS2, indicating substantially larger sequence divergence in COI gene sequence. Phylogenetically, the COI gene provided two haplotype groups with a high nodal support (≥87%), whereas ITS2 provided only one sequence type group with a high nodal support (≥92%). The result of COI gene sequence may suggest the presence of historical biogeographic barriers that bolstered genetic subdivision in the species. Different grouping pattern between COI gene and ITS2 sequences were interpreted in terms of recent dispersal, reflected in the ITS2 sequence. Finding of unique haplotypes and sequence types only from Beakryeng-Islet population was interpreted as an intact remnant of ancient polymorphism. As more samples are analyzed using further hyper-variable marker, further fruitful inference on the geographic contour of the species might be available.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

TV 스포오츠 프로그램 분석

朴淳哲,金凡植 成均館大學校 1982 論文集 Vol.31 No.-

This study is the analysis of TV sports program which had been telecasted on KBS and MBC during 1980 and viewer's inclination which is based on the questionaire treated by 825 Seoul citizens. The results can be summarized as following presentation. (1) It is considered to be very provising for the development in sports in Korea that TV are paying more attentions extending extra sport programs or even excluding regular program when there are important game of domestic or international, while sport articles in newspaper are reduced according to the relative importance of political, economical, social, cultural and so on. (2) Sport programs telecasted by both TV station during 1980 was 18 events by KBS and 10 events by MBC. Particulary, telecasting hours for 5 major popular events such as baseball, basketball, volleyball and boxing was total 73.4% by KBS and 68.9% by MBC, which is felt the lack of balanced telecasting and is considered to by more hours and frequency for figure skating, ice hockey and ski as seasonal sports and swimming, mountain climbing, golf, horse riding, cycling etc, as life sports or hobbies. (3) It is considered that TV should pay more attentions on the education for rules and technical direction of each items, enlightenment on necessity for physical education, health and beauty which is directly helpful for the life of citizens based on the idea of social education, by not being inclined to hook up for amusement or interest only. (4) People obtains sport news and informations from newspaper(56.2%) and TV (30.6%). It is considered to be much more hours of sport news as the better and various editing and planning since TV has transmitting effects of speedy and life sport news. (5) The ratio of satisfaction on current TV sport program was 9.0% while that of nou-satisfaction was 21.0%. It is considered to reject thoroughly the commercialization of sports due to exceeding commercialism and political tendency which they telecast if won, and don't if defeated, and to have accurate and thoughtful com ment by improving quality and standard of commentator. (6) By examining the ratio of enjoying TV sport program, that of woman (7.3%) was much lower than that of man (25.7%). It is considered being required to develop sport programs which woman enjoy since it is due to lack of programs for woman though having been sexual characterisitics of woman and prejudice on sports. (7) There are considerable difference between the events people enjoys in practice as hobbey or live sports and they like usually. The reason might be not answeres' personal situation but exterior environment of them. It is required to urgently train sport directors, to organize sport units administrative organization on government level, sport club or sport association of like-minded, and to secure unsufficient sport facilities or equipment.

The vernacular houses in Jeju island are never found in any other places and they also make it a particular living culture. The wind is acted as the binding force of the obvious culture formation in Jeju island with stone, especially the physical characteristics in the living style can be influenced by the wind. The conclusions are as follows. 1) As Mt.Hanra is located in the middle of Jeju, it is expressed by the difference in the arragement and style of vernacular houses. In the Southern Jeju, most of houses facing south and their style is the 'ㄱ-type'. In the other hand, there are houses facing east, west and having style of the '二-type' in the Northern Jeju. 2) The size of lumber used in vernacular houses in Jeju island is small but strong, '2-Goju 7-Ryang' is very available construction. 3) The height of stylobate and floor is lower than that of the Korean Peninsula, the height of them in the Northern Jeju is far lower than that of the southern Jeju. 4) The slope of roof is lower than that of the Korean Peninsula. This puts the stress on the defense against the wind rather than the rain. 5) The windbreaks in the Northern Jeju are three times as many as that of the Southern Jeju, stone walls in Jeju island are so higher than those of the Korean Peninsula and the windbreak forest is so much developed that the vernacular houses in Jeju island are characteristic of closing.
