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.

Objectives : Impaired processing of facial information is one of the broad ranges of cognitive deficits seen in patients with Schi-zophrenia. We aimed to elucidate the differences in brain activities involved in the process of facial working memory between schizophrenic patients and healthy comparison subjects. Methods : Twelve patients with schizophrenia were recruited along with twelve demographically matched healthy volunteers as a comparison group. Functional magnetic resonance imaging (fMRI) was used to assess cortical activities during the Perfor-mance of a 2-back working memory paradigm using images of neutral faces as mnemonic content. Rcsults : The patient group performed the tasks with reduced accuracy. Group analysis revealed that the left fusiform gyrus, the right superior frontal gyrus, the bilateral middle frontal gyri/insula, the left middle temporal gyrus, the precuneus, the quadrangular lobules and the vermis of cerebellum showed decreased cortical activities in the patient group. On the other hand, an increased level of activation in the lateral prefrontal cortex and the pahetal lobule was observed from the patient group, all in the right hemisphere. Conulusion : A decreased level of activity in the left fusiform gyrus among the patient group implicates inefficient processing of facial information. An increased level of activation in prefrontal and parietal neural networks from the patient group confirms earlier findings on the impaired working memory of patients with schizophrenia.

볶은 보리 및 참깨의 갈색도와 돌연변이 유발성

본 연구는 현재 국내에서 사용되고 있는 보리차용 보리와 참깨의 볶음정도와 아울러 Salmonella typhimurium TA98과 TA100균주를 이용한 Ames test에 의한 돌연변이 유발성 여부를 실험하엿따. 시판용 보리차는 갈색도로 보아 볶음정도가 다양함 을 알 수 있었고 업소용 보리차는 가정용 보리차에 비해 5배 정도로, 참기름용 참깨는 깨소금용 참깨보다 4배 정도 더 볶아진 것으로 평가되었다. 볶은 보리와 볶은 참깨의 수용성, 에탄올 용해성 및 에테르 용해성 성분에 대한 Ames test 결과는 모두 최고의 시험농도에서 돌연변이 유발능이 있다고 단정하기는 어려웠다. This study was undertaken to measure the degree of browning and mutagenicity by Ames test using Salmonella typhimurium TA 98 and TA 100 strains for roasted barley and sesame seeds used as food materials. The degree of browing of roasted barley for barley tea on the market showed a wide variation; barley for restaurant-use was heavily roasted (5 times) in comparison with home-use barley. Sesame seeds for oil extraction were more roasted (4 times) than those for seasoning. Water-, ethanol-and ether-soluble fractions from roasted barley and sesame seeds did not show any signs of mutagenicity, even at the extremely high concentrations of the extracts.

본 논문에서는 유아 교육용 프로그램을 구현하기 위해 필수적인 시나리오의 작성과 이미지 생성과정을 연구하고 그 결과로서 패밀리 프로그램을 개발하였다. 그리고 선정된 시나리오를 바탕으로 패밀리 게임기로 잘 알려진 8 비트 게임기에 사용되는 이미지 에디터인 FFe(Ramily Font Editor)에 대해 분석하고 이 이미지 에디터로 폰트, 맵, 맵 배치 설계, 스프라니트 폰트를 생성하여 패밀리 프로그램을 구현하였다. This paper describes two steps to implement infant education program. We selected a scenario to be the infant education program with systematized and organized education contents. With the selected scenario. we analyze the image editor, FFE(Family Font Editor), which used in the 8 bit family game device. We use the image editor to create font, map, map layout design and sprite of family program.

The purpose of this study is to demonstrate that horse racing is not gambling but investment. To demonstrate this, we used two methods. the first is logical reasoning three standards; information usage degree, benefit promotion degree, expected revenue degree is used. The second method is questionaire research of university student and professional group. The result of logical reasoning shows horse racing is not gambling but rational investment and the result of questionaire research is general public has blind prejudice that horse racing is a gambling. On the base of these result , this study suggested three step plans to improve and gain public favor in horse racing investment. the first step plan is marketing and education strategy to building human infrastructure in the short term. The second step plan is offering rational and unbiased horse racing investment infomation in the middle term, The last step plan is establish horse racing university to improve and gain scientific reasonableness. 본 연구에서는 투자와 도박을 판단히는 세 가지 기준인 정보의 이용정도, 효익 증대의 정도, 기대수익의 정도를 이용하여 경마가 도박이 아닌 '투자’ 라는 사실을 이론적이고 논리적으로 증명하였다. 또한 전문가와 일반인들의 경마에 대한 인식현황 파악을 위해 이론적 연구와 더불어 전문가 집단과 일반 학생 집단에 대해 간이설문조사를 실시하였다. 설문조사의 결과 대부분의 사람들이 투자와 도박에 대한 일정한 판단기준 없이 단지 ‘선입관’이나 ‘편견’에 따라 경마를 도박으로 보고 있었다. 이러한 이론적이고 논리적인 토대를 바탕으로 본 연구에서는 경마투자의 정당성 확보와 저변 확대를 위한 발전 방안을 3가지 제시하였다. 첫째, 본 연구에서는 단기적으로 인적 인프라를 구축할 수 있는 대 · 내외적인 홍보전략과 교육전략을 제시하였다. 둘째, 중기적으로 투명하고 공정한 경마정보의 제공방안을 정보의 신뢰성, 정보의 공유성, 정보의 차별성, 정보의 통제성, 정보의 적시성 측면에서 상세하게 제시하였다. 셋째, 본 연구에서는 장기적으로 학술장려 및 연구지원을 통해 경마를 새로운 사회과학이리는 학문영역(예, 경마투자론,경마투자학 등)으로 자리잡을 수 있는 방안을 제시하였다. 또한 최종적으로는 경마의 모든 분야를 포함할 수 있는 경마종합대학을 설립함으로써 일반인들에게 정당성과 타당성을 자연스럽게 인정받을 수 있는 학문적인 체계를 구축할 수 있도록 하였다.

Enantiomeric separation of naproxen is necessary in drug evaluation processes as the pharmacological activity of naproxen resides mainly in the (S)-enantiomer, The enantioseparation of naproxen was carried out with three different stationary phases. The methods were validated with the terms of linearity, intraday and interday precision, accuracy, selectivity and recovery. Among the selected stationary phases, ChiroSil DMB column with hexane : t-butylmethylether : acetic acid (60:40:0.1, v/v/v) as mobile phase showed the best enantioseparation of the naproxen in the commercial preparations. The wavelength for detection was 270 nm and flow rate was 2.0 mL/min. The contents of (S)-naproxen in the commercial preparations were 92.7 - 98.3%, indicating that all tested preparations were satisfactory to current regulation. However, the contents of (R)-naproxen as impurity in the commercial preparations were varied from 0.08% to 1.08%.
