This study was designed to identify the effects of foot position on electromyographic (EMG) activity of the quadriceps femoris during maximum voluntary contraction (MVC) in standing. Twenty young adults who had not experienced any knee injuries were recruited. Their Q-angles were within a normal range. They were asked to stand in five different foot positions (40˚externally rotated, 30˚ internally rotated, neutral, 20˚ plantarflexed, and 10˚dorsiflexed foot position). The EMG activities of the vastus lateralis (VL), rectum femoris (RF), and vastus medialis oblique (VMO) were recorded in standing by surface electrodes and normalized by MVC EMG values derived from manual muscle test. The normalized EMG activity levels (%MVC EMG) of muscles in the five foot positions were compared using repeated measures ANOVA. The EMG activity levels of the VL, RF, and VMO were the highest when foot was externally rotated. The EMG activity levels of the VL and RF were significantly different among the foot positions (p<.05). However, EMG activity levels of the VL, RF, VMO, and VMO/VL ratio did not show significant differences in each foot position (p> .05). The results suggest that the quadriceps femoris may be effectively activated by performing MVC a: an externally rotated foot position. Therefore, the externally rotated foot position can be considered as an effective foot position for quadriceps femoris strengthening exercise. Further studies are needed to identify whether there are differences in the effects of foot position on muscle strength after MVC exercise of quadriceps femoris in standing.

The purpose of this study is to increase satisfaction level when wearing a wig and to present the direction for the wig industry by examining the effect of the attitude of wearing customized wig on the quality of life and on the intention to purchase again and intention to spread word of mouth. As for the study method, survey was used to conduct frequency analysis, factor analysis, confidence analysis and regression analysis. The results are as follows. As for the study subjects, share of the married men in their 50s who graduated from high school was high. As for the monthly income, share of the self-employed making at least 1 Million Won to 2 Million Won or less was high. As for the levels of attitude towards wearing customized wig, they were five factors, while quality of life was classified into three factors. When the effect of the attitude when wearing customized wig on the quality of life was examined, it was demonstrated that there is statistically significant effect. Moreover, it is possible to know that there is significant effect on the intention to purchase again and intention to spread word of mouth. To this, wig`s cut should be harmonious with the hair in order to increase satisfaction level when wearing a customized wig. To develop ways to attach the wig easier and to develop product that is easy to handle, wig company has to conduct diverse researches. This customized wig is expected to increase confidence level of those wearing wig and to ensure willing and future oriented quality of life. Hopefully, diverse researches will be carried out on the realities of fashion wig and satisfaction level before and after wearing wig going forth.

인터넷 기술과 멀티미디어 기능의 발달로 인하여 디지털 콘텐츠는 새로운 성장 산업으로 주목받으며 다양한 경로를 통해 빠르게 보급되고 있다. 한 예로, 국내 디지털 콘텐츠 산업의 매출 규모 또한 2003년 이후 연평균 14.7%의 높은 성장률을 기록하고 있음에도, 정보 공학의 역기능 측면(저작권 침해, 부적합한 콘텐츠의 범람, 명예 훼손과 프라이버시의 침해)이 주요 문제로 대두되고 있다. 본 논문에서는 앞서 제시한 디지털 콘텐츠 유통 시 문제점을 해결하기 위하여 인터넷 환경 내 신뢰할 수 있는 디지털 콘텐츠 유통 아키텍처 (TDCDA)를 제시하였다. TDCDA는 콘텐츠 배포 시 신뢰성 확보와, 디지털 콘텐츠의 무결성 및 저작권 보호 메커니즘을 통한 안전한 콘텐츠 유통 방안을 소개하였고, 마지막으로 TDCDA의 알고리즘과 적용 방안을 제시함으로써, 실 웹 기반의 컴퓨팅 환경 내 활용 방안을 타진하였다. As the innovative internet technologies and multimedia are being rapidly developed, digital content is a remarkable new growth industry and supplied by various channel. For example, domestic sales volume in digital contents marked an annual increase of 14.7% since 2003. Against the merits of digital content distribution, Information reengineering aspects are getting more serious issues in these days such as infringement of copyright, flood of inappropriate content, invasion and infringement of privacy, etc. In this paper, we are making a suggestion of the TDCDA-Trusted Digital Content Distribution Architecture in order to solve above problems. TDCDA is provided to how well-define and design the trusted path in digital contents distribution in internet environments using a secure distribution mechanism, digital content integrity and copyright protection. Finally, we also proposed the TDCDA algorithm and applicable guidelines for feasible approach in real computing environment.

Objectives: This Study was accomplished in order to measure the effect which provide by Health Promotion Center in Forward Hospital and in order to examine the organizational culture of a military unit where cohort belong affects in health promotion program progress and result accomplished. Methods: Provided program consisted of 5 fields; smoking cessation, nutrition, stress management, exercise and drinking control program. This program was provided after weekly intervention method control and limitation control. And also, basic health level of before program compared with health level of after program including. During program process, variation of fat, blood pressure and blood sugar were informed cohort and program provider. This Study has been conducted from April 2010 to October 2010. Cohort were consisted of 35 officers including noncommissioned officers who were selected from three Forward Hospitals each 12 officers who showed over 2 metabolic syndromes at each Forward Hospital during general health check in that year. Program operators checked any improved effect of cohort's fat, blood pressure through everyday exercise and diet of cohort. And program operator used these results for health education and consulting. Three hospitals, each hospital has two health program operators. But, six operators unified programs before delivery and collected effects of program which delivered weekly. Difference for response of this survey by occupations were assessed with t - test or ANCOVA. Results: The ratio of Officer's participation in Health Promotion Program give positive affection to soldiers regarding health promotion activity. In case of Officers, who involved in high risk of metabolic syndrome, showed improved results through participation ratio of exercise, no smoking. A military unit which operated health promotion program showed variation of positive results regarding no smoking practice, participation ratio of health program were better than a military unit compared with no operating health promotion program.
