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.

An adaptive estimator to estimate the water quality in a river under unknown biased measurements environment is developed. In modeling the unknown measurement bias, it is assumed that the bias sequence is governed by semi-Markov process. By incorporating the semi-Markov probability concepts into the Bayesian estimation theory. an effective adaptive estimator which consists of parallel Kalman-type filters is obtained. Computer simulation results for the multiple-reach river system show that the proposed adaptive estimator have good estimation performance in spite of the unknown randomly switching measurement bias.

The present study is made to evaluate prognostic factors in 275 patients with moderate head injuries collected from entire 1105 head injured patients who were admitted to the Department of Neurosurgery, Chung Nam National University Hospital from January,1990 to September,1993. The results were as follows : 1) The severity rate of head trauma was as follows : 11.8 % in head trauma were severe (GCS 3-8), 24.8 % were moderate(GCS 9-12), 63.4% were mild( GCS 13-15). 2) The most common age group in moderate head injury was 3rd decade. 3) Males outnumbered females by almost 2.6 to 1. 4) The most common type injury in moderate head injuries was cerebral contusion followed by SDH. 5) The most common cause was motor vehicle accident followed by fall. 6) The most common combined injury was facial bone fracture followed by spinal injury. 7) In the overall outcome of 275 patients, 39 % made a good recovery, 32 % were moderately disabled, 13 % were left severely disabled, 2 % were vegetative, 14 % of the patients died. 8) 83 patients (32 %) were performed cranial operation under the diagnosis of EDH (21 patients), SDH (32 patients), ICH & DTICH (19 patients), IVH, contusion and FCCD or CSF leakage. 9) The mortality rate observed in patients operated for a cranial lesion was 17 % and the mortality rate in patients not undergoing surgery was 12.5%. The difference was statistically significant. 10) The period of hospitalization in moderate head injury was 4 weeks on an average.

저자들은 쇠고기에 의해 매개된 것으로 추정되는 출혈성 장염 및 이에 합병된 용혈성 요독 증후군 환자 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. We report case of hemolytic uremic syndrome(HUS) associated with hemorrhagic colitis. A 35-year0old man was admitted to a local hospital because of abdominal pain and watery diarrhea which had developed about 6 hours after taking roast beef. He was treated with intravenous fluids and antibiotics, but watery diarrhea changed to bloody in nature from the next day. He was transferred to our hospital due to progressive ascites and jaundice on his 8th day of illness. Examinations revealed ascites, jaundice, microangiopathic hemolytic anemia, thrombocytopenia and uremia. Sorbitol-negative Escherichia coli was isolated from his stool, which proved as Shiga-like toxin-negative E. coli, serotype O25. His conditions improved markedly after three times of plasmapheresis and intravenous fluids therapy, and the organism was not isolated from the follow-up stool culture.

In this report, the authors analyzed retrospectively 20 cases of pure traumatic basal ganglia hemorrhage(TBGH) which were diagnosed and treated in our hospital between January 1990 and Jun 1995. The TBGH incidence constitutes 1.4% of all head trauma. It occures were commonly among the younger male patient groups. The main causes of trauma was motor vehicle accidents. The overall mortality rate was 15%. Low initial GCS score, fixed pupillary reflex, pathologic reflex, poor motor response and large hematoma size were all poor prognostic factors, resulting a high mortality or passimistic outcome.

The purpose of this investigation was to analyze the actual condition of the year 2005 transferred students in the Gongju National Univ. of Education in terms of their demography, family background, social economic status, attitudes toward the University, values, psychological characteristics, attitudes toward the Research and Service Center for Students. Among 123 transferred students, 122 (99.1%) students replied to the investigation and were analyzed. The results lead to the following implications. First, most students’ age distribution went up due to the policy of the Ministry of Education to give an opportunity to those with teacher certificate who have never hired since 1970s. Second, they showed high expectancy toward becoming a teacher. Third, they revealed significant consideration about the moral and self-centered problems in the society. Fourth, they might be necessary for counseling or psychological supports to survive in the campus life because the age discrepancy between the transferred and normal undergraduate students are too wide to get along with each other in a campus, and they were worry about survival on the campus. Fifth, they revealed less problem about social relationships but more worries on faculty-student relationship, which seems to be related to their age.
