This study aims to analyse the consumer and regional dwellers preferences of nonghyup influenced by contributions of socio-economical using ordered logit model. The survey data were obtained from 225 adults in Chungnam province, cross sectional data in 2007. This paper especially estimates the impact of socio-economic characteristics, such as sex, occupation, school career, and emotional and subjective recognition of contributions of regional socio-economical and culture development, social welfare, It also examines the impact of recognition of cooperational level with local government`s policy, customer satisfaction ratings, degree of business ethics. The main results are as follows; the consumer and regional dwellers preferences of nonghyup is not affected by sex, occupation, school career. But the consumer and regional dwellers preferences of nonghyup is influenced by emotional and subjective recognition of contributions of regional socio-economical and culture development, social welfare, It also influenced by emotional and subjective recognition of policy cooperation level with local government, customer satisfaction ratings, degree of business ethics.

본 연구는 경제?사회적 요인이 여성의 생활만족도에 미치는 영향과 한계효과에 대하여 복지패널 3차자료를 활용하여 순서화로짓(Odered Logit)분석을 실행하였다. 이를 위해 사회적?경제적 요인들이 주요 독립변수로 채택되었으며 표준화 계수를 기준으로 주요 연구결과를 요약하면, 사회생활요인인 여가생활만족도, 사회적 친분관계만족도, 가족간 논의를 통한 문제해결, 긍정적 생활태도 등이 여성생활만족도 향상에 긍정적 영향을 미치는 것으로 나타났다. 그러나 경제적 요인인 주택유무, 가처분소득수준 등은 사회생활요인에 비교하여 적은 영향을 미치는 것으로 나타났다. 한편 가족간 불화, 저소득 가정 해당 등은 생활만족도에 부정적 영향을 주는 것으로 나타났다. 따라서 정부는 여성의 생활만족도를 향상시킬 수 있는 시설이나 프로그램 개선에 더 많은 정책적 관심을 가져야 할 것이다. This study aims to analyze affecting factors on life satisfaction level of the women and partial effects using Ordered Logit Model. For this purpose, socio-economic factors are selected as major independent factors. And the data used was from the third ‘Korea Welfare Panel Study’. Analysis shows that social life factors such as the satisfaction of leisure activities, social relationships, family member communication, and positive attitude to life had positive effects with the life satisfaction level of the women. However, economic factors such as home ownership, disposable income had a lower positive impact compared to social life factors. While, satisfaction level of women is negatively related with family member discordance, and classified low-income families. On the basis of these results, government should pay more attention to improve facilities and software that could meet women`s needs of social life satisfaction.

The delivery of optimal orthodontic treatment is greatly influenced by a clinician's ability to predict and control tooth movement achieved by applying known force systems to the dentition. It is important to determine the location of the center of resistance of a tooth or group of teeth to better understand the nature of their displacement characteristics under the various force levels. The purpose of this study was to define the location of the centers of resistance of various units of the upper anterior segment for lingually directed 100gm and 200gm force in a dry human skull. The units investigated were composed of four incisors and six anterior teeth. In addition, the effect of change in force magnitude on the location of the center of resistance of these units was investigated. The laser reflection technique was used to measure the initial displacements of the consolidated teeth under loading. The results were as follows : 1. The instantaneous center of resistance for the four anterior teeth was located vertically between level 4 and level 5―that is, at 37.4% apical to the cementoenamel junction level. 2. The instantaneous center of resistance for the six anterior teeth was located vertically just beneath level 5―that is, at 50.3% apical to the cementoenamel junction level. 3. Increasing force levels had little effect on the location of the center of resistance of a given unit. 4. The location of the instantaneous center of resistance shifted apically as the number of dental units consolidated increased.

The purpose of this study was to observe the changes of the third molars by orthopantomograms. The subjects were consisted of 55 cases in upper second molar extraction, 54 cases in lower molar extraction. The obtained results were as follows : 1. Initial long axis of 3rd molar is closely related to long axis of 3rd molar after eruption. 2. The favorable eruption of lower third molar appeared in both groups with pre-extraction angle under 24 and pre-extraction angle above 25.

Actually, it is difficult for the small-medium companies to invest time and resources in the area of technical research and the development of management methods with a view to improve the productivity. So, Small and Medium Business Administration has operated the co-research system of industry-school for the purpose of activating the company. Therefore, this paper handled the subject of a firm's work improvement. We suggested an alternative for the improvement of the manufacturing process through the calculation of standard time on the basis of time study, the reduction of unnecessary motion, and line balancing. In addition, MODAPTS method was applied to rule out the measurer's subjective biases in the course of calculating the standard time. Finally, this paper suggests the revised alternative that can derive following results such as the increase of production volume, the reduction of failure, and the decrease of work load by means of abbreviation of work time on process.
