The purpose of this study was to investigate the dimensional changes and surface morphology of dentures processed by various polymerization conditions. The measurements were done by taking radiograph and using vernier calipers and each specimen was observed on scanning electron microscope. Results obtained were as follows. 1. The difference of dimensional stability was not recognized between various polymerization conditions(heat-cured resin, pour-type resin, microwave-cured resin, and injection molding resin). 2. There were expansion and shrinkage in the occlusal dimension, shrinkage in the frontal dimension, and expansion in the lateral dimension. 3. Scanning electron microscope pictures of heat-cured resin showed dense and regular surface morphology. 4. Microwave-cured resin surface appeared more regular and smooth than pour-type resin but less dense and more irregular than heat-cured resin. 5. Scanning electron microscope pictures of pour-type resin with the lowest dimensional change showed the most irregular surface morphology.

This study was conducted to determine whether low intensity regular exercise following dexamethasone treatment could attenuate steroid-induced muscle atrophy. Method: 36 Wistar-rats(90-110g) were divided into six groups: control group(C), dexamethasone treatment group(D), sedentary group after normal sedentary period(C+S), sedentary group after dexamethasone treatment period(D+S), exercise group after normal sedentary period(C+E), and excercise group after dexamethasone treatment period(D+E). D, D+S, and D+E groups received dexamethasone injection(5mg/Kg) for seven days whereas C, C+S, and C+E groups received normal saline injection. Both C+E and D+E groups ran on a treadmill for 60 minutes/day(20minutes/4hours) at 15m/min and a 10$^{\circ}$grade for seven recovery days. Result: Post-weight(body weight before muscle dissection) of D group significantly decreased by 16.03%, and that of D+E group significantly increased by 15.51% compared with pre-weight(body weight before steroid treatment). TypeII muscle(plantaris and gastrocnemius) weights of D group were significantly lower than those of C group. Myofibrillar protein contents of typeII muscles of D group tended to decrease comparing with C group. In D+E groups, body weights and relative weights of typeII muscles(muscle weight(mg)/post-weight(g)) tended to increase comparing with D+S group. Conclusion: It is suggested that steroid- induced muscle atrophy can be ameliorated through low intensity regular exercise after dexamethasone treatment.

이 연구의 목적은 고용형태별 소득계층과 사회경제적 계층인식에 따른 건강상태 영향 요인을 알아보고자 하는데 있다. 한국노동연구원에서 실시한 한국노동패널 자료 중 18차 자료를 활용하여 만 20세 이상의 성인 5,158명을 최종 분석대상으로 하였다. 연구결과 정규직과 비정규직 모두 소득계층과 사회경제적 계층인식 간 통계적으로 유의한 차이가 있었으며, '중하'만이 계층 간 일치하였다. 이러한 결과는 우리사회의 정규직과 비정규직에 상관없이 실제 소득계층에 비해 상대적으로 낮게 인식하고 있기 때문으로 분석된다. 회귀분석결과 정규직은 사회경제적 계층인식이 낮을수록, 비정규직은 소득계층이 낮을수록, 사회경제적 계층인식이 낮을수록, 특히 비정규직의 경우 연금이 가입되지 않은 경우 건강상태가 나쁜 것으로 분석되었다. 따라서 비정규직 근로자들의 연금보험 납부금액의 적정성은 물론 소득이 상실되는 시점에 현실을 반영한 적절한 연금액이 지급 될 수 있도록 하여야 한다. 또한 다양한 교육과 홍보를 위한 정부, 경영계, 노동계간의 협력 등 다양한 방법을 모색하여야 한다.

Purpose: The purpose of this study was to determine factors related to regular walking exercise in the elderly using KNHNES data. Method: The study subjects, a total of 1437 adults over age 65, were classified into two groups based on their type of walking exercise: regular walking exercise group or irregular walking exercise group. The study variables were measured using scale physiological function, mental health status, chronic disease and quality of life. Results: The data was analyzed by $x^2$-test, t-test, and logistic regression using the SPSS 18.0 program. The factors related to regular walking exercise were male (OR=0.628, 95%CI=0.503-0.783), subjective health state (OR=0.832, 95%CI=0.751-0.921), thoughts of suicide (OR=0.753, 95%CI=0.586-0.967), hypoHDL-cholesterolemia (OR=0.742, 95%CI=0.591-0.930), and stroke (OR=0.604, 95%CI=0.366-0.997). Conclusion: The findings indicate that regular walking exercise in the elderly is related to physiological function, mental health status, and chronic disease. Therefore, providing for the education and awareness of health promotion for the elderly will may improve the quality of life in old age.

This paper investigated stretchability with fabric mechanical properties of one-way and two-way stretch fabrics. For this purpose, 1-way and 2-way woven fabrics were prepared using 150d PET/spandex covered yarns with different thermal treatment according to 4 kinds of wet thermal machines subsequently, fabric mechanical properties were measured and compared with regular PET fabrics. In addition, the garment formability of stretch fabrics was predicted and compared to regular fabrics according to wet thermal treatment. The weft stretchability of 2-way stretch fabric was about 10% higher than the 1-way stretch fabric. The compressibility of the stretch fabrics was 1.5 times higher than regular fabrics. The compressibility of stretch fabrics treated with CPB and rope type wet thermal machine showed higher values than other types of wet thermal machines. The bending rigidity of 2-way stretch fabric was lower than 1-way stretch fabric. Shear rigidity of 2-way stretch fabric was higher than 1-way and regular fabrics. Garment formability of 2-way stretch fabric was higher than regular and one-way stretch fabrics. Garment formability of 2-way stretch fabrics treated with wet thermal conditions under low tension showed the highest values.

Purpose: This study was done to investigate differences in health behaviors by job stress level in male and female workers in a large-sized company. Methods: Participants were 576 male and 228 female workers who completed questionnaires. Job stress was measured using the 'Short Form Korean Occupational Stress Scale (SF-KOSS)'. Health behaviors included smoking, alcohol consumption, regular exercise, and diet. Frequency, mean, SD, chi-square test, and multivariate logistic regression using SAS version 9.1 were used to analyze data. Results: Smoking, drinking and regular exercise rates were not different by job stress level in male or female workers. Only regular diet was significantly different by job stress level in male and female workers. From multivariate analysis, the alcohol consumption rates for female workers differed by marital status. Regular exercise rate was significantly related to age for male workers and type of employment for female workers. After adjusting for demographic and work-related characteristics, regular diet significantly differed by shift work for male workers and marital status and shift work for female workers. Conclusion: The findings of the study indicate that nursing interventions should be developed to manage job stress to improve diet habits for male and female workers in large-sized companies.

This study was conducted to examine dietary behaviors according to residence status and ethnicity of university students in Yanbian, China. For the subjects, 334 university students (Male=141, Female=193) answered a questionnaire about perception of weight control, dietary patterns, health habits, residence status, and ethnicity. Perception of weight, meal frequency, favorite kind of food, meal finishing time, skipping breakfast, type of breakfast, snack frequency, late-night snack frequency, exercise frequency, regular life, and sleeping time were all significantly associated with residence status. Motivation of weight control, meal frequency, regularity of meal time, meal volume, favorite kind of food, exercise time, and regular life were all significantly associated with ethnicity. University students who lived with their parents perceived their weight more properly, exhibited a more positive dietary pattern, and lived a more regular life than those students who lived in a dormitory with their friends. Chinese students exhibited a more regular dietary pattern and lived a more regular life than the Korean-Chinese students. As a result, both environmental and inherent factors are related with the dietary behaviors of university students in Yanbian, China. These data could be used to help university students in Yanbian, China attain a healthy diet.

ZnPc and CuPc molecules stacked similar way in the film, but showed different growth modes in thermal evaporation. The distribution of CuPc crystals did not change by the film thickness, whereas the distribution of ZnPc became random as the increase of the film thickness. The disc type nanograins of CuPc were quite regularly distributed at the initial growth regime and the regular distribution of nanograins was kept during the film growth. On the other hand, ZnPc consisted in ellipsoid shaped nanograins and the distribution of nanograins was not regular in the initial growth regime. The irregular distribution of nanograins changed to the regular mode at the later growth regime by showing structure factor in GISAXS measurement. The different initial nanograin distribution in ZnPc and CuPc was related to the different nanostructure in the mixed layer with C60 to form the bulk heterojunction.
