이준희,이정은,김대선,정민의 해양환경안전학회 2024 해양환경안전학회지 Vol.30 No.1
본 연구에서는 해양공간 통합관리 수단의 지원책으로 활용되는 해양공간 정책 시뮬레이터 기술에 대한 한국, 중국, 일본, 미국, 유럽 등 주요 5개국에 대한 정량분석을 위한 유효특허 1,474건을 도출하고, 연도별, 국가별 특허출원 동향 및 워드 클라우드 분석을 통해 국내 기술 경쟁력 및 국내·외 기술 트렌드를 파악하였다. 분석 결과 해양공간 정책 시뮬레이터 기술의 경우 중국(1,254건, 85.1%) 주도의 특허출원이 활발하게 이루어지고 있으며, 세부 기술별로는 어업환경 변화예측 및 활용 시뮬레이터(AC)가 392건(26.6%)으로 가장 높은 것으로 나타난다. 핵심 키워드 변화를 통해 최근에는 다중 데이터의 수집과 데이터의 탐지, 예측, 평가 등으로 기술 트렌드가 이루어지고 있음을 확인하였으며, 중국 주도의 시장 독과점 및 선점에 대비하기 위해 주변 기술에 대한 특허출원 고려 및 표준화 선점 등의 연계 전략을 통한 대비와 정부 차원의 해양공간 정책 시뮬레이터 기술 연구개발에 대한 적극적인 정책적 지원이 필요함을 진단하였다. In this study, 1,474 effective patents were derived for quantitative analysis of five major countries, including Korea, China, Japan, the United States and Europe, for marine space policy simulator technology used as a support for integrated marine space management means, and domestic technology competitiveness and domestic and foreign technology trends were identified through annual and national patent application trends and word cloud analysis. This diagnosed the need for active policy support for research and development of marine space policy simulator technology at the government level and preparation through linkage strategies such as patent application consideration and standardization preoccupation for surrounding technologies to prepare for China-led market monopoly and preoccupation.

이준희 慶星大學校 1996 論文集 Vol.17 No.4
The study investigated 366 participants in the like-minded persons' club and 383 participants which individually performs the sports, which do the sports activities in sports center and like-minded persons' club Individual Participants closely examined the formation course of social attitude, and the analysis of data acquired the following conclusion by use of the stepwise regression analysis. 1. In the motive for the participation oh sports upon the type of participation, those who take part in the sports like-minded persons' club appeared the fellowship, formation oh character, activities, curiosity, and accomplishment motive higher than the individual sports participants, and in the physical motive, the individual sports participants showed its higher degree. 2. In the social attitude, the participants in the sports like-minded persons' club shows the social attitude higher than the individual sports participants. 3. Effect which the motive for participants of sports has upon the social & emotional attitude formation. 1) In case of participants in the sports like-minded persons' club, the physical motive, the motive for the formation of character and the accomplishment motive appeared to have the noted effects in the male, and the physical motive and motive of curiosity have the noted influences in the female. The physical motive wholly appeared to have the biggest effects. 2)In case of the individual sports participants, the motive for the formation of character and the physical motive appeared to have the noted effects in the male, and the physical motive had the noted influences in the female. The physical motive wholly appeared to have biggest effects. 4. Effect which the motive for participation of sports has upon the formation of social unification attitude. 1) In case of the participants in the sports like-minded persons' club, the motive of friendship, character formation and activities appeared to has the noted effects in the male, and the motive for the character formation and friendship had the noted effects in the female. The motive for friendship wholly appeared to have the biggest effects. 2) In case of the individual sports participants, the motive of character formation friendship, and physical motive appeared to has noted effects in the male, and the motive for the character formation and activities had the noted effects in the female. The motive for formation of character wholly appeared to have the biggest effects. 5.Effects which the motive for participation of sports had upon the socialization attitude 1) In case of the participants in the sports like-minded persons' club, the motive of character formation, activities, curiosity and friendship appeared to has noted effects in the male, and the motive for the character formation and activities had the noted effects in the male. The motive for character formation wholly appeared to have the biggest effects. 2) In case of the individual sports participants, the motive of character formation, curiosity, accomplishment, friendship and activities appeared to has the noted effects in the male and the motive for the character formation and activities, physical motive and friendship had the noted effects in the female. The motive for formation of character wholly appeared to have the biggest effects. 6.Effects which the participation motive had upon the social control attitude 1) In case of the participants in the sports like-minded persons' club, the motive of character formation, physical motives, and friendship appeared to has the effects in the male, and the motive for the character formation had the effects in the female. The motive for character formation wholly appeared to have the biggest effects. 2) In case of the individual sports participants, the motive of character formation, accomplishment, curiosity and physical motive appeared to has the noted effects upon the social control attitude in the male, and the motive for the character formation and activities, physical motive and curiosity had the noted effects in the female. The motive for formation of character wholly appeared to have the biggest effects.
展伸用 强力輕合金材料의 時效處理에 따른 衝擊靭性에 관한 硏究
李俊熹 동아대학교 공과대학 부설 한국자원개발연구소 1982 硏究報告 Vol.6 No.1
A Study has been performed on the effect of impact toughness on the aging treatment of Al-Zn-Mg-Cu(X), X-Cr and X-Zr with a high contents Zinc. Using Vickers hardness tester, We investigated the aging characteristics of three alloys under various temperature of heat treatment. We studied the toughness using Instrumented Charpy machine. The experimental results showed that the toughness were increased by X-Cr and X-Zr compared with X alloy. But there is no effect in the aging characteristics. It was believed that the toughness increased was due to grain size refinement and homogeneous distribution of small particles. As age hardening increases, decrease of absorbed energy was due to a decrease of crack-propagation energy. Both age hardening velocity and maximum hardness value turned out to be high. As age hardening, the fracture mode changes from brittle grain boundary fracture to ductile dimple type transgranular fracture.
