It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

In the case of Daegu subway arson in 2003, it was found out that the evacuation system could not play its own role in the dense smoke and blackout during the fire. Due to the dense cloud of smoke and blackout, the people could not easily find the way out. Proper emergency light plan considered cognitive characteristics of evacuees is set up in such places, if so it will be a great help for evacuation. The information obtained through visual sense induces behaviors intuitively. So, effective evacuee guidance is implemented by installing various evacuation guidance devices (emergency lights and luminous egress guide-lines). In connection with this topic, Jeon Gyu-yeob(2011) carried out an on-the-spot experiment focused on changes in visual perceptional evacuation environment and evacuation abilities. And on the basis of the results, he carried out a study on changes in evacuation behaviors through visual perceptional restriction. However, studies on characteristics of visual perception that has an effect on behaviors of evacuees and evacuation behaviors are not sufficient. Therefore this study examined the effect of background luminance of the emergency light induced to recognize the emergency light. Therefore, to produce a device for adjusting the brightness experiment, this study simulated evacuation experiments were performed for 136 people. The value of the result indicated by seek time of emergency light, evacuation time and emergency light cognition distance.

Far East asian history in ancient and the middle ages was expansion of territory by the territorial ambitions and the series of revenge among mutual dynastys of Far East asian continent. Gogooryu dynasty is more offensive than the defensive against foreign country in BC I century and I century and 2 century. Gogooryu dynasty is more defensive than the offensive against foreign country in 3 century. Gogooryu dynasty is more offensive than the defensive against foreign country in 4 century. Gogooryu dynasty's attack and the defensive againast foreign country is same in 5 Century. Gogooryu dynasty is 9 times more offensive than the defensive against foreign country in 6 century. Gogooryu dynasty is 12 times more defensive than the attack against foreign country in 7 century.

공복 시 Caffeine 투여 후 일회성 운동이 흰쥐의 인슐린 및 골격근의 GLUT-4 발현에 미치는 영향

정일규,오명진,김영표,김종오,윤재석,서태범,윤진환 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.5

This study was done to investigate the effects of caffeine ingestion on the expression of GLUT-4 in rats' skeletal muscle(soleus m) and blood insulin level after 12 hr fasting condition and one hour treadmill running. Total 19 rats(Sprague-Dawley) who were 7week Did were used for experimental subjects and raised for 1week in the room controled the air temperature and relative humudity(22℃ and 50%). They were divided three groups ; 12hr fasting group(F group, n=5), fasting+exercise group(FE, n= 7) and fasting+caffeine+exercise group(FCE group, n=7). FG and FCE group performed treadmill running for one hour and the treadmill speed was 18m/min that was supposed to be moderate exercise to rats. Each Dr rats in FCE group was forced to he given the caffeine solution(5mg/kg, Sigma Chemical co.) through stainless steel tube directly to their stomachs one hour before treadmill exercise. Immediately after treadmill running, we anesthetized them with the mixed solution(Ketamin 80g/kg and Rompun 5ml/kg) to draw 3ml blood from heart four insulin analysis and then obtained the rats' soleus muscle for GLUT-4 expression. We found that FCE group showed significantly higher GLUT - expression then the other groups and FE group showed the lowest GLUT-4 expression. This rusults suggest that the endurance type of exercise in fasting condition inhibit the GLUT-4 expression in working muscle and the caffeine helped to facilitate the GLUT-4 expression during endurance type of exercise. The future studies needed to confirm the action of caffeine to increase the GLUT- 4 and the mechanism.

1. The recorded plants in this survey were 72 families, 168 genera, 249 kinds. 2. The number of species of plants flowered monthly were most in May as 119 kinds and least in January as 3 kinds(Yucca tricreana, Camellia japonica, Senecio vulagalis). According to the seasons the number of species of flowered plants were 255 kinds in Spring, 247 kinds in Summer, 144 kinds in Autumn, 34 kinds in Winter. 3. In comparision with the results of another previous studies the flowering period was early two months in herbaceous plants, one month in woody plants. 4. Through four seasons Senecio vulgaris and Sonchus loeraceus were flowering, three seasons 8 kinds(Trifolium repens, etc.), not continuosly for two seasons 8 kinds(Tradescantia reflexa, etc.). 5. In the character of habitat pattern, native species were 136 kinds, ornamental species 76 kinds, cultured species for food 26 kinds, naturalized species 11 kinds. 6. Native species of 41 kinds which are not recorded in the previous studies(Jung, 1991) are added to this paper newly.

고속도강을 이용한 CFRP 복합재료의 드릴가공 특성

조규재,박종남,정용운 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.1

복합재료는 각 종 기계부품, 우주항공산업, 자동차의 내장재와 구조재, 건축구조물, 선박 재료, 스포츠용품 등 다방면에서 유용하게 사용되어지고 있다. 복합재료는 여러 가지의 대체 재료로서 타 산업에 비하여 활용의 가치가 높다. 그러나 기계가공분야에서는 가공의 어려움으로 인하여 활용도가 미흡한 상태이다. 따라서 본 논문에서는 CFRP를 수직형 머시닝센터에서 고속도강 드렬로 가공한 후 흘 가공 입 · 출구부에서 표면이 고르지 못함을 확인하였으며, 가공을 할수록 유동형의 긴 칩에서 분진형태로 변하는 칩의 형상 등을 관찰하였다. Composite materials are widely used in all kinds of machine parts, aerospace industries, internal and structural materials of cars, building structures, ship materials, sporting goods, and others. It is worth while to use the composite materials as various substitutions compared with others. But it is limited to use them in the field of the mechanical processing because of the difficulties in cutting. Thus it is proved that the surface roughness is in and out of the hole processing after cutting the CFRP with HSS drilling in the vertical machining center. And it is observed that the more it is processed, the more the fluid long chip is changed into the powdered chip.
