In recent years, rollover has became an important safety issue for a large class of vehicles. Even though rollovers constitute a small percentage of all accidents, they have un proportionally large contribution to severe and fatal injuries. Rollover is the primary cause of fatalities in accidents especially involving sports utility vehicles(SUVs). There is an urgent need to develop both analytical and experimental tools to predict rollover propensity of vehicles and to improve their design from the viewpoint of rollover resistance. In this paper, the optimum design for SUV suspension is determined through sensitivity analysis against rollover propensity of SUV suspension system using response surface methods. Verified optimum SUV suspension is using Fishhook 1b (rollrate feedback)test selected by NHTSA.

장영진(Jang, Young-Jin),김학덕(Kim, Hak-Duk) 한국웰니스학회 2015 한국웰니스학회지 Vol.10 No.4

시대가 흐를수록 신체활동에 관련한 관심은 계속 증가하고 있다. 정책적으로도 엘리트스포츠발전만이 아닌 생활체육에 대한발전을 도모하면서 사람들의 복지와 웰니스를 위한 활동이 중요시되고 있다. 생활체육지도자의 활동은 생활체육참여자에게 효율적이고 바른 운동법과 같은 지식전달과 생활체육에 대한 이미지 등의 직·간접적인 영향을 끼치므로 그 과정을 파악하기 위한 해석학적인 접근이 필요하다. 생활체육지도자들이 지도방식을 스스로 만들어가는데 있어서 신념과 상호작용은 어떠한지에 대해 알아보고 이에 대한 문화형성과정을 알아보고자 하였다. 신념은 생각, 가치관, 행동, 태도, 판단 등에 영향을 미치며, 상호작용을 통해 타인의 교육방법을 모방하고 흉내내면서 자신만의 교육방법을 만들어나간다. 이는 생활체육지도자 개인의 질적 발전을 가져오고 생활체육참여자에게 영향을 끼침으로서 추후 ‘생활체육’에 대한 긍정적 이미지와 필요성을 사람들이 몸소 느끼게 될 것이다. 본 연구를 통해 생활체육지도자의 문화에 대한 새로운 인식을 알아봄으로써, 생활체육지도자들이 본인의 권리를 내세울 수 있는단체의 출범, 생활체육지도자들의 처우개선 및 단결력 증진을 통한 사회경제적 위상 높이기, 개정된 시스템에 맞춰진 협회나 위원회의 활동 진행 등 생활체육이 나아가야 할 방향을 제시하고 발전하는데 일조할 것이다. As time has passed, attention to physical activity has been increasing. Activities for people’s welfare and wellness is been getting important planning policy development for Elite sports as well as sports for all. As sport for all instructors’ activities have direct and indirect effects on participants of sport for all instructors such as efficient knowledge delivery or images of sport for all, it is needed analysis approach to apprehend the process. This article attempts to examine what kind of beliefs sport for all instructors have and interaction they conduct when they establish their guiding forms, and process of cultural formation from that. The beliefs influence on thinking, value, behaviour, attitude, making decision, and so on. Moreover, they establish their own educational methods copying and following others’ methods via interaction. This cause qualitive development of sport for all instructors and let people have positive images and the necessity of sports for all impacting on participants. This study is expected to help establishing an organisation for sport for all instructors’ rights, enhancing their social and financial status through improvement of their condition and the power of unity, and signposting how sports for all develop such as process of activities of institutions and organizations with revised systems.

계약생산에 의한 기업 주도형 유기낙농단지의 형성: 전라북도 고창군을 사례로

장영진 ( Young Jin Jang ) 한국경제지리학회 2015 한국경제지리학회지 Vol.18 No.4

본 연구는 대규모 유가공업체 매일유업과 전라북도 고창군 낙농가 간 유기농 원유 계약생산을 대상으로, 계약생산이 고창군에서 시작된 배경을 고찰하고, 계약생산의 실제와 계약주체 간 관계를 중심으로 계약생산의 특징을 규명하고, 이로 인해 나타나는 지역 낙농업의 변화를 설명하였다. 사례지역의 유기농 원유 계약생산은 시장개방으로 위기에 처한 기업의 제품 다각화 전략과 고창군의 청정 환경, 그리고 지방정부와 낙농가의 긍정적 태도가 맞물리면서 성립되었다. 고창군의 유기농 원유 계약생산은, 한편으로는 참여 농가의 생산규모를 선택적으로 증가시킴에 따라 역내 낙농가 간 생산규모의 격차를 유발하고 있으나, 다른 한편으로는 계약농가의 유기농가로의 전환을 통해 역내 유기농업의 확산을 가져옴에 따라 관행농업 중심의 계약생산에 대한 일반의 우려를 불식시키고 있다. The objective of this study was to review how contract farming started in Gochang-gun and identified its characteristics among the contracting parties and the consequent changes in the region’s dairy industry with regard to the contract production of organic milk in Gochang-gun, Jeollabuk-do, Korea in conjunction with the Maeil Dairy Industry Corporation. The contract was established in keeping with the product diversification strategy of the company after a crisis due to opening of the market, taking advantage of the clean environment of Gochang-gun and positive attitudes of the local government and dairy farmers. The expansion of the participating farms led to a production gap among dairy farms in the region; however, the overall concern over the conventional practice of contract farming was mitigated as the organic farming spread with the conversion of the contract farms to organic farms.

To gain knowledge of oral health behavior-related factors influencing the oral health of seniors, I carefully explained and administered a questionnaire to elderly citizens over 65 who agreed to participate in my interview in Daegu from September 5th to 30th. After eliminating questionnaires containing errors I surveyed 379 remaining questionnaires and obtained the following conclusions presented in summary as follows. 1) The general characteristics of those surveyed were 54.6% male and 45.4% female in gender; 34.0% were aged 65-69, 24.8% aged 70-74, 26.4% aged 75-79, 2.4% aged 85 and older; 66.8% were married, 1.6% divorced, 2.9% separated, 28.8% bereaved; 31.7% had monthly household income less than 500,000 won, 26.5% from 500,000 to 1,000,000 won, 12.4% from 1010,000 to 1,500,000 won, 11.9% from 1510,000 to 2,000,000 won, followed by 17.2% more than 2010,000 won. 2) Level of oral health behaviors according to the general characteristics graded on a five-point scale showed an average of 2.62 points, with significant difference by gender or marital status. 3) Subjective state of health according to general characteristics on a five-point scale showed significance with a high average of 3.01 points; for gender, ‘women’ at 3.11 points scored higher than ‘men’ at 3.02 points. Based on marital status, ‘separated’ subjects averaged 3.68 points, ‘married’ 3.10 points, ‘bereaved’ 2.96 points (p <0.01). In addition, post-test differences between groups showed that differences existed between groups based on marital status: married, divorced, bereaved and separated (a: b). 4) Correlations of associated factors for subjective oral health status were (for subjective health status) daily interference level (r = 0.642), impact on general health (r = 0.568), tooth-brushing activity (r = 0.245), regular dental checkups ( r = 0.188), adequate nutritional intake (r = 0.221), showing a positive correlation between a similar degrees, with subjective oral health status greater the higher the score in each of the above categories, interference with daily living, impact on general health, tooth-brushing activity, regular dental check-ups, sufficient nutrition intake. 5) With oral health behaviors as the dependent variable, and impacting factors as independent variables in a regression analysis showed that independent variables explained 21.4% of oral health behaviors. Overall, F value was 10.041, statistically significant. Significant factors in the variables` impact on oral health behaviors included gender (β =- 0.136), tooth-brushing (β = 0.253), oral checkups (β = 0.145), and subjective health status (0.206). Among the factors, tooth-brushing method showed the highest standardized regression coefficient and thus having the most impact.

A survey was conducted among directors and high ranking officials of 500 facilities in Seoul, 6 metropolitan cities and Gyeongsangbuk-do on the basis of intentional sampling for two months from July 03, 2006 to August 31, 2006, to get to the bottom of effective linkage of welfare services for the elderly from the perspective long-term care serivice, in an attempt to propose measures to effectively build various networks. The result of survey can be summarized as follows 1. The importance of linkage to other organization indicated 4.14±0.75 out of full score of 5. A statistically significant difference was found in the gender, post, invested organization, frequency of participation in education and training. the degree of service exchange with other organization and employees indicated 3.50, which suggests such exchanges are performed well 2. Degree of service education, sufficiency of business expense, degree of support for linkage, degree of social and institutional environment, sufficiency in terms of number of facility, and the degree of satisfaction displayed positive correlation among factors related to the satisfaction with the linkage, which implies that the satisfaction with the linkage increased in proportion to the degree of service education, sufficiency of business expense, social and institutional environment, sufficiency in terms of number of facility, and the degree of satisfaction with service. 3. The satisfaction with the linkage was found to increase in proportion to the level of education, the degree of social and institutional environment, the sufficiency in terms of the number of facility, the intimacy with each organization and the satisfaction with service, as it was indicated that the gender, education background, degree of social and institutional environment, the sufficiency in terms of the number of facility, the intimacy with each organization and the satisfaction with service were among variables -which significant affect the satisfaction with the linkage. Therefore, future studies need to focus on the reinforcement of the linkage with the service organization which reflect the ,willingness to use among the users of facility, after expanding the infrastructure of the welfare facility for the elderly, such as real-cost welfare facility or small-scale recuperation and care facility, etc, which the elderly can use conveniently and easily as well segmented service linkage with public healfh centers and hospitals for the elderly, besides the factor which affect the satisfaction with the service linkage put forth in this study.
