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.

의무고용제도 재설계 방안

김종진,장창엽,유완식,김언아,이정주,류정진,강필수,최종철,남용현,김윤삼 한국장애인고용촉진공단 고용개발원 2008 연구개발 Vol.- No.2

현행 우리나라 의무고용제도는 장애인구의 급격한 증가, 장애인차별금지 및 권리구제 등에 관한 법률의 도입 등 외부환경변화에 신축적으로 대처하지 못하고, 경증장애인 중심으로 의무고용제도가 운영됨으로써 중증장애인의 고용배제가 우려되고 있다. 본 보고서는 이러한 문제점을 해결하기 위해 의무고용제도의 일자리 확대와 고용증가를 통해 중증장애인의 고용기회를 확대할 수 있는 정책방안을 제시하기 위한 것이다. 본 보고서는 (1)의무고용 사업체의 의무고용 산정인원에서 자립장애인 제외 (2)현행 2% 의무고용률을 3%로 상향 조정 (3)사업체가 고용하는 중증장애인에 대한 더블카운트(2배) 가산제도 도입 (4)의무고용률 미달 사업주에 대한 부담금 차등징수의 4가지 정책방안, 제도 합리화 차원에서 장려금 지급방식의 개선과 사업주의 장애인에 대한 인식개선 방안을 제시하였다. 정책방안에 대한 영향분석 결과 의무고용 적용대상자에서 비장애인과 고용상 차별되지 않는 자립장애인(6등급)을 의무고용 산정인원에서 제외하는 경우 의무고용 사업체의 고용인원은 23,296명이 감소해 고용률은 1.35%에서 0.88%로 감소하였고, 의무고용 사업체의 장애인 일자리 수는 미고용인원의 증가로 15,152개가 증가하였다. 그리고 기금은 부담금이 631억원 증가하고, 장려금이 352억원 감소해 983억원의 수지개선 효과가 발생하는 것으로 나타났다. 의무고용 사업주의 의무고용률 3% 인상 방안은 의무고용률 상향 조정에 따른 미고용인원의 증가로 장애인의 일자리 수는 43,101개가 증가하고, 기금은 부담금이 1,709억원 증가하는 반면, 장려금은 293억원이 감소해 2,002억원의 수지개선 효과가 발생하는 것으로 나타났다. 의무고용 사업주가 고용하는 중증장애인을 2인으로 더블카운트 하는 중증장애인 가산제도의 도입은 의무고용 사업체의 장애인근로자가 67,261명에서 79,685명(1,2등급만 포함시 75,685명)으로 증가하여 고용률은 1.35%에서 1.60%(1.2등급만 포함시 1.52%)로 증가하고, 의무고용률 미달 사업체의 미고용 인원이 감소하여 2,745개의 일자리가 감소하였다. 그리고 기금은 부담금이 118억원 감소하는 반면, 장려금은 418억원이 증가해 536억원의 수지악화가 발생하는 것으로 나타났다. 의무고용률 미달 사업체의 고용유인을 위해 고용률 1.0%미만, 1.0-1.5%, 1.6-2.0% 미만에 대해 각각 20%, 10%, 5%의 할증률을 순차적으로 가중하여 부과하는 부담금 차등징수 방안(3차년까지의 효과임)은 1.0% 미만 사업주는 86만원, 1.0-1.5% 사업주는 64만원, 1.6-2.0% 미만 사업주는 58만원의 부담기초액을 부과할 때 고용률은 1.35%에서 1.53%로 증가(1.6-2.0% 미만 사업주는 의무고용률 2%를 달성)하고, 미고용인원의 감소로 장애인의 일자리는 8,836개가 감소하는 것으로 나타났다. 그리고 기금은 부담금이 58억원 감소하여 수지는 악화되었다. 이상의 네 가지 방안은 모두 장애인의 고용증대를 가져온다는 측면에서는 유효하지만, 장애인의 일자리 확대를 통한 중증장애인의 고용을 증대한다는 정책목표를 달성하는 데에는 한계점을 안고 있기 때문에 어느 한 정책만을 선택하기보다는 정책효과를 극대화하기 위해 정책결합(policy mix)을 이용하는 것이 바람직함을 제시해주었다. 즉, 의무고용 적용대상자 조정방안/의무고용률 상향조정 방안과 중증장애인 가산제도/부담금 차등징수 방안을 조합 또는 모두 동시에 선택하는 경우 의무고용 사업체의 장애인 일자리 수의 확대와 중증장애인 고용을 동시에 달성하고, 기금의 수지균형도 달성 가능한 것으로 나타났다. The mandatory employment quota system of Korea does not reflect the changing external factors such as the growing population of people with disabilities(PWDs) and the enactment of the Anti-discrimination Law for People with Disabilities. The current employment quota system focuses on people with mild disabilities thus excluding people with severe disabilities from employment. The purpose of this report is to propose a plan in order to increase employment opportunity for the severely disabled through the reform of the employment quota system. This report analyzes the following : (1) exclude grade 6 disability from mandatory employment quota (2) raise the employment quota from 2% to 3% (3) implement the double counting for employers that employ the severely disabled (4) differentiate the amount of levy collected from corporations that are unable to meet the quota. The aforementioned plans are useful in that they increase employment for people with disabilities. However, there are limitation to reaching the policy objectives by increasing jobs for people with severe disabilities. Therefore, to maximize the effects we should consider policy mix of these four policies. In other words, by mixing the policies of adjusting the employment quota target/raising the quota ratio and implementing the double count/differentiating the amount of levy, we can achieve the goal of increasing jobs for the severely disabled and maintain equilibrium between incomings and outcomings.

Objectives: This study examined the relationship of fatigue to medical utilization, occupational accident and sickness absence. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project, 2002~2004). A total of 30,146 employees categorized within the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were recruited. A structured-questionnaire was used to assess the participants' sociodemo-graphics, job-related factors, health-related behaviors, personality trait, self=perceived fatigue (MFS) and the frequency of medical utilization, occupational accident and sickness absence. Data on medical utilization and occupational accident were confirmed from company health records. Chi-square test and logistic regression analysis were used to elucidate the relationship of self-perceived fatigue to medical utilization, occupational accident and sickness absence. Results: In logistic regression analyses, self-perceived fatigue was associated with medical utilization (outpatient), occupational accident and sickness absence although the strength of the associations was higher in the blue collar workers except for medical utilization. For medical utilization, the white collar worker's adjusted odds ratios of outpatient utilization for workers scoring in the third quartile and the highest quartile, compared to workers scoring in the lowest quartile were 1.50 (95% CI: 1.20-1.87) and 2.16 (95% CI: 1.69-2.75), respectively. The blue collar workers' adjusted odds ratios of outpatient utilization for workers scoring in the second (OR: 1.23, 95% CI: 1.06-1.43), third (OR: 1.42, 95% CI: 1.22-1.66) and highest quartile (OR:1.83, 95% CI: 1.55-2.17), respectively, compared to workers scoring in the lowest quartile were statistically significant. However, no associations were found between fatigue and inpatient utilization for either the white or blue collar workers. The blue collar workers' adjusted odds ratios of being injured for workers scoring in the second, third and highest quartile were 1.41 (95% CI: 1.00-2.00), 1.57 (95% CI: 1.10-2.22) and 2.41 (95% CI: 1.69-3.44), respectively, compared to those scoring in the lowest quartile, but, those of the white collar workers were not significant. There was more likely to an increased risk of sickness absence in workers scoring in the second, third and highest quartile compared to those scoring in the lowest quartile in both white and blue collar workers, but the magnitudes of risk were higher in the blue collar workers than the white collars workers. Conclusion: This result suggests that fatigue is a determinant predictor of medical utilization, occupational accident and sickness absence, and that the pattern of risks for the three outcomes differs according to the occupational type. Some limitations of this study and considerations for future study were also discussed.

정신분열병 환자에서 얼굴 영상의 작동기억 장애 : 기능자기공명영상연구

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.

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.

용선 탈황조업에서의 반응속도론 적 고찰을 실험실적 연구와 물질이동론에 근거한 반응모델을 통하여 수행하였다. 실조업에서와 같이 용선측의 교만강도가 큰 조건에서는 탈황 반응속도는 슬래그내 황의 물질이동율속에 의해 지배됨을 확인하였다. 슬래그내 황의 물질이동계수에 영향을 미치는 속도론적 인자는 슬래그의 점도와 교반강도비다. 탈황반응속도에 관한 기존의 타 연구자 결과를 본 연구에서의 반응모델로 재분석한 결과, 용선내 황의 물질이동보다는 슬래그내 물질이동 율속에 의해 결정되어짐을 확인하였다. Reaction kinectics of hot metal desulfurization has been studied through the interpretation of experimental results by a reaction model based on the mass transfer theory. The desulfurization rate is controlled by mass transfer or diffusion of sulfur in slag phase in real practice where the stirring intensity of hot metal is relatively high. Kinetic Factors affecting the mass transfer coefficient of sulfur in slag are slag viscosity and stirring intensity. Evaluation of other worker's data on desulfurization kinetics indicate that the rate is controlled by mass transfer of sulfur in slag rather than in metal.

The purpose of this study was to analyze the present condition of college physical education the survey was carried out with thirty seven national or private colleges the findings of this study could be summarized as followings; 1. College physical educaion was largely devided into three fields-physical education, art education, and education transforted from required subject. The most widely carried field was that of art education. 2. Various opportunities for college physical education were given to students, and there were thirteen col-leges where more than ten subjects were taken. Especially in Seoul National University, forty subjects were tak-en. But the number of colleges where less than four subjects was sixteen. 3. Twenty two colleges took subjects concerned with high-class sports such as leisure, recreation, golf, ski and so on. The subjects were composed to make students go through high-class sports so they are suppposed to strengthen students' abilities to adapt themselves to modern society. 4. To take a unit, students could freely choose subjects among three diffrent fields of college physical edu-cation. And the larger part of students took one or two subjects.

The purpose of this study was to apply the instructional strategies for conceptual change prescribed by Posner et al(1982) to the astronomic content domain taught in the elementary and middle school and to analyze the characteristics of students' knowledge revealed in the test before, during and after the instruction. Also, it was to investigate the intercorrelation of cognitive levels, spatial ability and science achievement. The major findings of this study are as follows: 1. Students had a great variety of misconceptions related to the motion of the moon before the instruction, that is, the phases, the names of phases and the cause of changing phases by the moon's orbit about the earth, the moon's appearance and location at the given time, the relative positions of earth, moon and sun during a lunar eclipse, the cause that a full moon is not at the line of node once a month. In the analysis of students' responses concerning the cause of changing phases of the moon and a lunar eclipse, the results indicate that the great majority of students had rote learning rather than meaningful learning in the middle school. 2. Students' reponses during the instruction concerning the changing phases of the moon and the predictive knowledge about the motions of the earth and the moon were analyzed. 1) According to the results of the test given before and after experiment, after discussion, achievement score of the whole of subjects and groups in both preformal and formal cognitive levels appeared to increase linearly. 2) There was no statistically significant differences of achievement scores before and after experiment, after discussion between preformal group and formal group in cognitive levels. 3. Distribution of achievement scores according to the whole of subjects and groups in preformal and formal cognitive levels shows that there was a statistically significant difference between pretest and posttest. 4. Types of conceptual changes concerning the cause of changing phases of the moon that occurred from pretest to posttest were classified as accommodation, incomplete accommodation, assimilation, no change and no model. Six of the seven students starting instruction with alternative frameworks didn't sustain those alternative models throughout instruction. Five of these six students accommodated completely and the last one partially. Seventy-nine percentage of students taking instruction with fragmental models assimilated correct propositions at the end of the instruction. These results suggest that conceptual change model prescribed by Posner et al(1982) has promised the meaningful learning to students taking with fragmental models, especially in cases where students with misconception enter instruction. 5. High correlation between achievement score of simple-recall items and that of written items in pretest and posttest indicates that the higher students got the score in simple-recall items the better they also performed in written items. However, there was no statistically significant differences among cognitive levels, spatial ability and science achievement in the whole of subjects and groups according to the cognitive levels.
