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.

In order to investigate the sleep habits of farmers in a rural area, we studied 270 subjects(farmers) in a rural area from August 14, 1995 to August 19, 1995. Sleep habits were analyzed according to age groups(3 groups of 18-30, 31-50, over 51 years) and sex. The results were as follows : 1) The mean sleep length was 6.7±1.5 hours, and was longer in female than in male. In the above 51-year-old age group, sleep length was significantly shorter than those in the other two age groups. 2) The mean sleep latency was 21.6±21.5 minutes, and was longer in female than in male. There were no significant differences in sleep latency among age groups. 3) The sleep onset time was later in the 18-30-year-old age group than in the other two age groups. The awakening time was earlier in the over 51-year-old age group than in the other two age groups. 4) One hundred and four subjects(38.5%) complained difficulty falling asleep, 196 subjects(72.6%) complained fragmented sleep, and 86 subjects(31.9%) complained early morning awakening during the past two weeks. Difficulty falling asleep and fragmented sleep were more common in females than in male. 5) One hundred and seventeen subjects(43.3%) had napped during the past two weeks and there were no significant differences among age groups. 6) One hundred and sixty five subjects(61.1%) experienced daytime drowsiness during the past two weeks and there were no significant differences among age groups. 7) Ninety-one subjects(33.7%) reported nightmares, 32 subjects(11.9%) reported sleeptalking 3 subjects(1.1%) reported sleepwalking, and 15 subjects(5.6%) reported bruxism during past two weeks.

This paper presents the detection and diagnosis of air-conditioner electromagnetic sound through noise measurements. Electromagnetic sound originating from the motor is an unpleasant source of unwanted noise that should be detected at the manufacturing stage. A detection system using sound measurements was built and a detection algorithm based on FFT analysis is presented. Soun measurements are preferable over direct vibration measurement because it is non-contact and low cost. Experimental results show that our sound measurement system can detect electromagnetic sound effectively compared to using vibration measurements.

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

Proliferation of T lymphocytes has been determined by a threshold of signals generated by the interaction between interleukin-2 (IL-2) and its spedific membrane receptor (IL-2R). Regulation of IL-2R expression on the surface of lymphocytes is important in the generation of cytototocix T cells and lymphokine-activated killer (LAK) cells carrying anti-tumor effector functions in the body. To obtain the ideas in designing in vivo immunotherapy using biological response modifiers, this study examined the effects of the interferon(IFN)s, steroid, or colchicine on the IL-2R expression and proliferation of human peripheral blood lymphocytes(PBL). As incubation time was lengthened up to 72 hours, the number of Tac-positive cells and prolongation potential of human PBL upon stimulation wit IL-2 or mitogens were increased. IFN-α resulted in a significant inhibition of IL-2R expression induced by IL-2 but IFN-Υ had no effect. Colchicine or dexaamethasone also inhibited IL-2R expression and cell proliferation induced by IL-2 or mitogens. These findings suggest that IL-2R expression and proliferation of human PBL are inhibited by IFN-α, colchicine, or dexamethasone.

Although it is becoming widely accepted that medulloblastoma and cerebral primitive neuroectodermal tumor(PNET) are identical tumors occuring at different locations, there are some controversies in their origin and pathological classification. As a method of investigating whether the tumors are identical in pathological aspects, immunohistochemical characteristics of medulloblastomas and cerebral PNETs were compared in this study. Also the prognostic significance of the immunohistochemical findings in modulloblastoma patients was analyzed. Clinical features of twenty-seven patients with modulloblastoma and eleven patients with cerebral PNET were reviewed, excluding tumors with significant cellular differentiation such as ependymoblastoma, pineoblastoma and neuroblastoma. The presence of glial fibrillary acidic protein(GFAP), neurofilament(NF), S-100 protein, vimentin synaptophysin, and epithelial membrane antigen (EMA) was examined with immunohistochemical method and the differences of the results between the two tumors were statistically analyzed. The positive rates of NF and synaptophysin were significantly higher in medulloblastomas(p = 0.006 and 0.003, respectively) and so was the positive rate of vimentin in cerebral PNETs(p=0.004). S-100 protein showed a higher positive rate in cerebral PNETs although it was not statistically significant Univariate and multivariate analyses did not show any significant correlation between the duration of survival and the presence of cellular antigens.

본 연구는 초등 방과후학교에 대한 운영과 방과후학교지원센터의 추진정책에 대한 외부강사의 인식조사를 통해 보다 실증적인 자료를 얻기 위한 목적으로 수행되었다. 이를 위해 부산지역 방과후학교에 참여하는 외부강사 267명을 대상으로 운영실태 및 이에 대한 그들 자신의 평가, 방과후학교지원센터에서 수행하고 있는 외부강사 인력풀 관리, 정책 및 채용에 대한 정보 제공, 연수 등에 대한 인식을 조사하였다. 그 결과 외부강사들은 방과후학교 운영의 목적을 사교육비 절감에 두고 있었다. 학생들의 효율적인 참여를 위해 학년별 정규수업 마치는 시간을 고려한 시간표 구성, 시간당 일정 강의료에 학생 수를 반영한 강사료 책정, 학교차원의 적극적인 홍보를 가장 효과적인 활성화 방안으로 인식하고 있었다. 한편, 이들은 방과후학교 외부강사로 활동 하면서 학생을 가르치는 즐거움을 가장 큰 보람으로 느끼고 있었지만, 동시에 고용의 안정성이 확보되지 못해 불안을 느끼고 있었다. 또한, 방과후학교지원센터에서 운영하는 인력풀에 약 60%가 등록하여 활동하고 있었다. 지원센터의 명강사 또는 우수프로그램 인증을 통해 명강사로서의 자부심뿐 아니라 채용이나 강사료에도 긍정적인 도움을 받을 수 있길 기대하고 있었는데, 인증점수 환산 시 학생관리능력에 대한 배점이 좀 더 강화되어야 한다는 인식을 갖고 있었다. 더불어 방과후학교지원센터에서 주관하고 있는 연수에 각 분야별 전문가 및 현재 활동하고 있는 우수 외부강사가 지도강사로 참여하여 좀 더 현실적인 도움을 제공받길 원하고 있었다. 이러한 외부강사의 인식조사는 방과후학교 활성화를 위한 정책 수립 시 기초자료가 될 수 있을 것이다. 특히, 최근에 설립되어 아직 검증되지 않은 방과후학교지원센터에 대한 외부강사의 인식조사는 보다 체계적인 방과후학교 운영을 위해 구체적인 시사점을 줄 수 있다. The purpose of this study was to investigate instructor’s opinion about management of after-school and supporting centers for after-school, especially for both accreditation systems for best instructor or program and training systems for instructor. This study examined instructor's opinion by their education levels, teaching programs, and job types, which were not regarded by previous studies. The key findings of this study are summarized in the following. First, instructors thought that the main purpose of after-school is to reduce private education expenses. However, because the tuition fee of after-school is getting higher, the government should consider more financial support for after-school. Second, to activate after-school, school needs to advertise actively about instructors and programs. According to instructors’ opinion, the most efficient method of advertisement is using school letters. Also, in order to reduce school teacher's work, school needs to set advertisement systems for after-school. Third, it is needed to strengthen the functions of supporting center for after-school, because instructors get information like program advertisement, employment, or related policies from supporting center's homepage. Forth, training programs for instructors should be held by regular basis. Instructors want that period of training program needs to be held during vacations which instructors have spare time. Also, contents of training programs need to be adjusted practically, so instructors can use in their classes.
