The fractal-based method for describing rubbed surface texture has aroused great interest. The determination of rubbed surface topography is believed to be extremely important in the areas of contact mechanics, adhesion and friction. In order to describe topography of the rubbed surface, the wear test was carried out with annular surfaces of wear testing specimens in dry friction. furthermore, the relation between the fractal dimensions and the frictional conditions are also investigated and fractal descriptors was applied to rubbed surface with image processing. Fractal dimension can be determined by sum of intensity difference of image surface pixel. Fractal dimension increased according as the applied load and sliding distance increase. Topography of the rubbed surface can be effectively obtained by fractal dimensions.

Adipocytokines (adiponectin, leptin and resistin) are known to play a major role in development of cardiovascular disease (CVD) and intervention program is effective in reducing CVD risk factors. However, intervention program to improve the CVD risk factors including adipocytokines has been less studied. This study investigated the effects of 12-weeks worksite intervention program on cardiovascular risk factors, adipocytokines and nutrients intakes in industrial workers. 157 industrial male workers (32 metabolic syndrome (MS) subjects, 125 healthy subjects using age-matched stratified random sampling) received 5 face-to-face counseling based on their health profiles. Anthropometry, biochemical parameters and nutrients intakes were measured. The diagnosis of MS was adapted from modified NCEPATP III criteria (2001) and Asia-Pacific definition criteria (2000) for waist circumference (WC). After the intervention program, WC, BMI, SBP, insulin, leptin and intakes of total energy and fiber were significantly decreased (p < 0.05), while adiponectin was significantly increased (p < 0.05) in MS subjects. The WC, BMI, SBP, total cholesterol, LDL and HDL-cholesterol, HbA1c, leptin and intakes of total energy, protein and fat were significantly decreased (p < 0.05) and adiponectin was significantly increased (p < 0.05) in normal subjects. Multiple linear regression revealed that adiponectin was positively correlated with HDL-cholesterol (p < 0.01). Leptin was positively correlated with WC (p < 0.01), and resistin was positively correlated with HbA1c (p < 0.05) and intakes of total energy (p < 0.05), and negatively correlated with HDL-cholesterol (p < 0.05). The results of the 12 weeks intervention showed a positive impact on adipocytokines and nutrients intakes of industrial workers to reduce cardiovascular risk factors. Further research is needed to verify a tailored long-term worksite intervention program including adipocytokines as a protective factor for the CVD. (Korean J Nutr 2011 44(4): 292 ~ 302)

본 연구는 정부신뢰의 특징과 그 영향요인을 밝히는데 목적이 있다. 이러한 연구목적에 따라 전국적인 조사결과를 토대로 사적신뢰, 단체참여, 정치참여 및 관심 지역, 사회경제적 배경 등의 요인들이 우리나라 정부신뢰에 어떻게 영향을 미치는지를 분석하였다. 그 결과, 첫째 사적신뢰 및 일반신뢰를 포함하는 대인신뢰가 입법부, 사법부, 행정부 등 모든 정부기관과 이를 통합한 정부신뢰 변수에 영향을 미치고 있었다. 둘째, 수평적 단체뿐만 아니라 수직적 단체 가입 및 활동도 정부신뢰에 긍정적인 영향을 미치고 있었다. 셋째, 정치적 요인으로 투표참여, 정치관심과 같은 소극적인 정치참여는 정부신뢰에 긍정적인 영향을 미치는 반면 정당가입과 정치활동과 같은 적극적인 정치참여는 정부신뢰에 부정적인 영향을 미치는 것으로 나타났다. 넷째, 중·소도시 및 농촌지역 주민이 대도시 지역주민보다 정부신뢰가 낮은 것으로 나타났고, 영·호남지역에 거주하는 주민의 경우는 다른 지역에 비해 정부신뢰가 높은 것으로 나타났다. 단, 영남과 호남지역 주민의 신뢰하는 기관은 서로 다르게 나타났다. 다섯째, 사회·경제적 배경 변수는 정부신뢰에 상대적으로 큰 영향을 미치지 않는 것으로 나타났다. 연령이 높을수록, 그리고 남성보다는 여성이 대체로 정부기관을 신뢰하는 경향을 나타내었고, 다른 변수들은 별로 영향을 미치지 않고 있었다. 이렇게 나타난 분석결과를 토대로 본 연구에서는 정부신뢰를 증가시킬 수 있는 방향 및 정책적 함의에 대해 논의하였다. This study examines the characteristics of trust in the Korean government and clarifies the factors that affect this trust of government. For the purposes of this study, a number of factors were analyzed. including interpersonal trust, civic association participation, political participation and interest, region of residence, and individuals; socioeconomic status - all of which were deemed to affect trust in the Korean government. Data were obtained from more than 7,000 survey responses collected from all 14 provinces and metropolitan areas in Korea. This research finds that ① interpersonal trust positively affects trust in all three branches of the government - legislative, judicial, and executive, ② hierarchical civic association participation as well as horizontal participation positively affect trust in government. ③ while voting and political interest have a positive impact on trust in government, political party membership and political activities like demonstrations and petitions have a negative impact on trust in government, ④ residents who live in small and medium-sized cities as well as rural areas show lower government trust than those in big cities, and the residents in the Yongnam and Honam provinces show higher government trust than those in other areas. and ⑤ older people show higher government trust than younger, and females exhibit higher government trust than males. Overall, this paper discusses how to improve trust in government and offers implications for further research.
