우수한 영양성분과 생리활성 물질을 함유하고 있는 토마토에 대해서 품종별 완숙 토마토의 부위 와 토마토 가공제품에 대하여 ascorbic acid, lycopene, ${\beta}$-carotene과 ${\alpha}$-carotene의 함량 차이 를 조사한 결과 토마토의 품종에 따른 ascorbic acid 함량 수준의 차이가 존재하며, 부위별에서는 pulp보다 jelly가 월등히 높은 함량 수준을 나타내었다. 토마토 가공제품의 ascorbic acid의 함량은 토마토 주스 제품들이 타 제품들보다는 ascorbic acid 함량 수준이 높았지만, 가공 시 토마토 이외에 첨가되는 다양한 첨가제의 영향에 따른 것으로 ascorbic acid 함량 수준에 따라 제품을 평가하기에는 다소 무리가 있었다. 품종별 lycopene의 함량은 품종별 pulp와 jelly 부위 간의 lycopene의 함량 수준은 일정한 차이가 존재하지 않음을 알 수 있었다. 대부분의 품종의 부위별 ${\beta}$-carotene의 함량 수준의 큰 차이를 나타내지 않았지만, 여용 품종은 pulp 부위 보다 jelly 부위가 2.7배 높은 함량 수준을 나타내었다. 품종별 ${\alpha}$-carotene의 함량은 pulp와 jelly 부위 모두 가장 높은 함량 수준을 나타내었으며, yellow carol 품종의 경 우 lycopene, ${\beta}$-carotene 함량의 경우 부위별과 상관없이 가장 낮은 함량 수준을 나타내었으며, ${\alpha}$-carotene의 경우는 pulp 및 jelly 부위 모두 검출되지 않았다. 토마토 가공제품별 lycopene, ${\beta}$-carotene, ${\alpha}$-carotene의 함량 수준은 전제적으로 유의성 있는 차이를 보였는데 이는 토마토 가공제품은 토마토의 가공 형태 및 첨가제로서의 역할에 따른 lycopene, ${\beta}$-carotene, ${\alpha}$-carotene의 함량 수준의 차이가 존재함을 알 수 있었다. 본 연구를 통하여 우수한 특성을 가진 토마토의 다양한 형태로의 섭취, 즉 국내에서 생육형태로만 섭취되어지고 있는 토마토에 대하여 다양한 토마토 가공제품과 함께 사용하여 영양적으로 우수한 다양한 조리법을 개발하는데 도움이 되고자 한다. For tomatoes containing valuable nutrients and biological active substances, this study examined differences in the ascorbic acid, lycopene, ${\beta}$-carotene, and ${\alpha}$-carotene contents in processed tomato products according to tomato cultivar and the part of fully ripened tomatoes. According to the results, the ascorbic acid content was different among tomato cultivars, and it was far higher in jelly than in pulp among the parts of tomatoes. The ascorbic acid content in processed tomato products was higher in tomato juice than in other types of tomato products, but the difference was mainly from various additives used in addition to tomatoes; therefore, it was somewhat unreasonable to compare the ascorbic acid content among the products. It was found that the lycopene content was not significantly different between pulp and jelly in each cultivar. In most of the cultivars, the ${\beta}$-carotene content was not significantly different according to the parts, but in cultivar yeoyong, the content was 2.7 times higher in jelly than in pulp. The ${\alpha}$-carotene content was highest in both pulp and jelly for all the cultivar, and the lycopene and ${\beta}$-carotene contents were lowest regardless of parts for cultivar Yellow Carol. ${\alpha}$ carotene was not detected in either pulp or jelly. The lycopene, ${\beta}$-carotene, and ${\alpha}$-carotene contents showed significant difference among processed tomato products, and the difference came mainly from the type of processing and additives. Tomatoes have superior characteristics, but they are usually consumed uncooked in Korea. Thus, this study aimed to contribute to the various forms of consumption of tomatoes, that is, the development of various nutritionally excellent cooking methods using processed tomato products.

우리나라의 경우 PR의 다양한 업무 영역(마케팅 커뮤니케이션, 중역의 연설 훈련, 조사와 평가, 위기관리, 언론 분석, 지역사회 관계 관리, 이벤트 관리, 공공관계관리, 종업원커뮤니케이션, CI작업, 주주와 재정관계 관리 등) 중 특히 퍼블리시티(publicity)에 가장 많은 비중을 두고 있다. 주요 조직체들의 홍보 부서의 일반적 대내외 업무 중 가장 중요한 업무는 보도 자료 작성과 언론에 보도된 기사 스크랩 정리 및 분석과 같은 대 언론 업무이다. 이는 대부분의 조직체들이 대 언론 관계 즉, 퍼블리시티라는 전통적인 홍보업무에 많은 비중을 두고 있음을 말해주고 있는 것이다. 그런데 이러한 퍼블리시티 업무를 흔히 ‘언론플레이’ 라는 부정적인 뒤앙스로 받아들이는 경향이 있다. 따라서, 본 연구에서는 PR 실무자들이 PR 현장에서 경험하게 되는 다양한 차원의 윤리 문제들 중에서 직업윤리와 언론 윤리에 관한 인식에 관하여 살펴봄으로서 PR 실무자들의 윤리 의식 함양에 도움을 주고자 한다. Media relations is one of the most important areas of PR in Korea. And PR business ethics is the cause of misunderstandings and complications in PR media relationship. Therefore, PR practitioners' perception about PR business ethics is important part. Along with the rapidly developing PR industry, the ethical aspects of PR are gradually being taken seriously in executing PR projects and activities, PR practitioners have the social responsibility to preserve media clean in media relations because they primarily keep various information of organizations. In order to guarantee peoples right to know and the free flow and the free flow of information, the PR ethics must be closely examined.

In order to evaluate performance of anti-vibration gloves, it is necessary to measure the transmitted vibration to the hand and the applied forces at the same time while gripping the vibrating handle. In the study a system was developed to measure both the vibration and the forces. The system consists of a measurement handle with eight strain gauges and two accelerometers and a PC-based system with a software for signal processing, evaluation of the hand-transmitted vibration and for control of applied forces in the pre-determined range. The handle was installed on the vibration shaker which is strong enough so as not to be affected by dynamic coupling with the hand-arm. Whole procedure of ISO 10819:1996 to determine the vibration transmissibility of anti-vibration gloves was programmed into the system. As an example of the application, three subjects joined the test to get vibration transmissibilities of 9 anti-vibration gloves where each glove was tested twice a subject. Average and standard deviation of the corrected vibration transmissibility were also calculated. All tested gloves fulfilled criterion for M-spectrum(TR(M)<1.0), but one glove fulfilled criterion for H-spectrum(TR(H)<6.0 ).

Wheel bearings on passenger and commercial cars are one component to have lives similar to the lives of light bulbs and human. Specifically rolling contact fatigue lives are probabilistic in nature. To validate durability performance during the development process of wheel bearings most of endurance test is performed on a test rigs prior to vehicle test due to cost and time. But the durability of the same model of bearing is affected by diversity such as structural concept, loading system, and vibrating characteristics of test rig itself. This paper shows the development of the instrumented device that can measure strain on the wheel bearing and the relation between durability of wheel bearing and measured strain under the same loading condition on two test rigs. The first result shows the different endurance performance and strain, but after the adjustment loading condition two test rigs have the equivalent severity.

본 연구에서는 영상콘텐츠 수용과 확산 과정을 이해하기 위한 이론적 근거가 되는 로저스의 혁신의 확산(diffusion of innovation)이론과 디지털 미디어 확산과 사회적 특성을 중심으로 영상콘텐츠의 의미와 해석, 소비자 환경변화에 따른 영상 콘텐츠의 수용과 확산을 핵심적으로 다루고자 한다. The study of the diffusion of innovation is the study of how, why, and at what rate new ideas and technology spread through cultures. Everett Rogers explained Diffusion of Innovations as a theory that analyzes, as well as helps explain, the adaptation of a new innovation. It helps to explain the process of social change. An innovation is an idea, practice, or object that is perceived as new by an individual or other unit of adoption.
