The Republic of Korea Army predicted that the continuous decline in fertility rate and the low birth rate, one of the biggest issues in our society, would lead to a security crisis due to a lack of military personnel, and revised the Military Service Act in 2010 to prevent enlistment of 'clearly mixed races', which had previously restricted enlistment. made it compulsory As a result, 50 children from multicultural families enlisted in the military in 2011, and the Military Manpower Administration at the time predicted that more than 8,000 people would enlist every year after 2020. This poses another challenge for the Army. A lack of understanding and respect for different languages, religions, and eating habits can lead to conflict among members, which will lead to weakening of combat power. Therefore, through a case study of multicultural application by world powers, the history of success and failure of respect for multiculturalism and the current policy of respecting multiculturalism of the U.S. Army are studied to examine the direction of our army.

In this study, the main items to be improved were identified with children's foodservice facilities in Anyang area, which have remained at low hygiene management levels for three years from 2019. The grades were divided into the Sprout groups if the previous level of meal hygiene management insufficient, and the Fruit groups if excellent. As a result, there were various items with low scores depending on the grade in facilities and the timing. Throughout the three years, the Sprout group had lower scores of all six areas than the Fruit group, and in particular, the score of 'preservation meals' was the lowest. In conclusion, it is necessary to recognize that meal hygiene management items to be improved are different from each grade in facilities, identify items to be thoroughly managed in advance, and provide appropriate guidance.

Existing bibliometric laws have been established on the basis of well defined science journals with a long history. However, the history of technology innovation research in Korea is young and the scope of the research is diverse compared with other fields. The main purpose of this research can be summarized as follows : Can the traditional bibliometric laws be used to explain the young and diverse data derived from technology innovation studies in Korea. Second, we want to compare the explain ability of the power law, compared with the traditional laws in the field. Third, we propose a quasi index related to the well-known impact factor to measure the contribution of a journal or a group of journals to the development of innovation research in Korea. We confirmed Lotka's and Bradford's laws which are used to measure the productivity of researchers, but we could not support the validity of Price's Square Root law as Nicholls (1998) could not. On the citations to journals, Garfield's laws is not observed. However, the power law fits well the citations to author, journal, article, and book. The estimated parameters between 1.6 and 3.5 are similar to the values in the range of 1.5 and 3 in previous studies. Finally the quasi index shows that the influence of international leading journals on innovation research in Korea is weaker than on innovation studies in the world.

Korea has achieved a high startup rate by promoting government-led startup policies for national economic and industrial development. However, as high as the startup rate is, the closure rate of startup companies can be judged to be insufficient for the qualitative growth of the domestic startup ecosystem. This study aims to investigate how to improve the survival rate of startups by overcoming the valley of death from a location environment perspective. It analyzes the effects of technology orientation and market orientation of start-ups on management performance and the moderating effects of economic, accessibility, and network factors that constitute the location environment. To achieve the research objectives, the empirical analysis was conducted on start-up companies that received corporate support projects from innovation intermediary organizations. The results show that R&D capability of technology orientation has a significant effect on management performance, and market information generation and market information response of market orientation have a significant effect on management performance. As for the moderating effect, accessibility, a sub-factor of the location environment, has a positive moderating effect on the relationship between technological innovation and managerial performance, and the location environment (economy, accessibility, and network) has a positive moderating effect on the relationship between market information generation and managerial performance. This study compared and analyzed previous studies on the success and failure of start-ups and identified common factors. In addition, this study provides policy implications for the sustainable growth of startups through empirical analysis and interview with stakeholders. For future research, it is necessary to compare and analyze start-ups in metropolitan areas and non-metropolitan areas. In addition, it is necessary to study startups that have moved out of the region and into the metropolitan area to find ways to develop the regional startup ecosystem.

This paper investigates efficiency analysis to IT HRD programs in the dynamic perspective. First, empirical result shows that government fund of IT research center is significantly associated with SCI thesis and the more trial goods and SW development is connected with the more patent and technology transfer. Second, ITRC program has been operated efficiently since 2000. Finally, dynamic efficiency analysis implicates that ITRC program is more efficient than other IT SoC program and foreign student support program. The reason why ITRC program is more efficient is generated not from the effect of imitation by catch-up strategy to developed HRD programs, but new operation system introducing and utilizing HRD performance system.

사회생활을 하는 사람이라면 하루에 꼭 한번 정도는 하는 일이 있다. 출퇴근, 회의, 그리고 자판기 이용이 그것이다. 이른아침 출근을 위해 지하철 무인 패스 판매기를 이용하고 출근해서는 나른한 오후시간을 깨우기위해 으례 커피자판기를 이용하기 일수이고 여가시간을 이용해서는 친구들과 가벼운 스티커 사진촬영을 하는 등 우리의 자판기 이용 문화는 이미 현대인 너무나도 보편화되고 친숙해져버린 생활의 한 단면이 되어버렸다. 그렇다면 자판기는 언제쯤 인간의 일상사 속에 등장하기 시작했을까? 놀랍게도 자판기의 기원은 기원전 215년으로 거슬러 올라간다. 당시 이집트 사원에서 `성수(聖水)`를 판매하기 위해 만들어졌던 동전식 조작장치가 최초의 자판기라는게 정설로 받아들여온 사실로서 동전을 넣으면 투입된 동전이 받치고 있던 접시가 기울어져 그 기울기가 원래대로 돌아올 때까지 출구로 물이 나오는 원리를 이용한 것이다. 누가 만든것인지는 명확히 밝혀지지 않았으나 확실한 것은 자판기의 역사가 이미 기원전으로 거슬러 올라가고 인간생활에 뿌리내린 역사가 깊다는 것이다. 아무튼 이렇게 자판기가 나타난 이래로 17세기에 키산드리아 과학자 헤론이 쓴 책이 발견되기 이전까지 자판기는 잊혀진 발명품이었다. 그러나 그 책의 발견과 함께 사람들은 옛문헌 속의 발명품의 실용성에 관심을 기울이기 시작했고 차츰 영국의 선술집과 여관 담배 자판기가 등장하기 시작했으며 자판기는 식민지까지 보급될 정도로 선풍적인 인기를 끌었다. 19세기에 들어서는 담배 이외의 물건을 판매할 수 있는 자판기에 관심을 두기 시작했고, 자유주의 사상이 풍미하던 시절, 영국에서 나타난 금서(禁書)자판기에서부터 상업문화가 발달한 미국의 껌볼 자판기에 이르기까지 자판기는 점차로 그 영역을 넓혀갔고 또한 발전해 왔던 것이다. 그러나 자동판매기의 이러한 급속한 발전과 소비영역에서 역량의 강화는 비단 단순한 소비패턴의 변화에서 기인하는 것이라고는 보기 어렵다. 이는 노동집약적 산업구조에서 기술집약적 산업사회로의 전환에 따른 대량생산, 대량소비, 소비패턴 변화 등의 마케팅 환경의 변화에 따라 새로운 유통구조의 출현이 요망되었기 때문이었다. 따라서 슈퍼마켓, 쇼핑센터 등의 새로운 유통구조의 출현 외에도 인건비의 상승, 장소의 제한 및 구입의 편리성 등에 따라 무인 자동판매기의 등장은 필연적이었다고 볼수 있다. 이후 자판기의 판매상품의 범위는 더욱 넓어졌고 컵라면, 인형, 마음에 드는 음악만을 골라담는 CD,휴지,구두광택기,사진스티커,콘돔,장난감,담배,여행용품,스낵,아이스크림 등등 소액권과 손가락만 있으면 살 수 있는 물건의 가짓수는 헤아리기 어려울 정도가 되었으며, 그만큼 유통혁신의 기구로서 산업에 미치는 영향 역시 증대되고 있으며, 이러한 경향은 21세기 정보화,첨단화 경향에 발맞추어 더욱 진보된 형태로 발전해오고 있다.

The Internet of Things(IoT) security has more need than a technical problem as it needs series of regulations and faultless security system for common purposes. So, this study proposes an efficient key management in order that can be trusted IoT data in cloud computing. In contrast with a key distribution center of existing sensor networks, the proposed a federation key management of cloud proxy key server is not central point of administration and enables an active key recovery and update. The proposed key management is not a method of predetermined secret keys but sharing key information of a cloud proxy key server in autonomous cloud, which can reduce key generation and space complexity. In addition, In contrast with previous IoT key researches, a federation key of cloud proxy key server provides an extraction ability from meaningful information while moving data.

In composite materials, the adhesion and interfacial properties were the most important factors to obtain high performance of mechanical properties. This review paper had been focused on the micromechanical evaluation methods for the interfacial property historically. The interfacial property of fiber-reinforced composites (FRC) could be evaluated using only a single fiber and matrix via various micromechanical testing methods. Self-sensing due to the fracture behavior of FRC could be determined and discussed more critically and clearly using electro-micromechanical evaluation. In this paper, the research trends for micro-mechanical evaluation of composites was summarized, and their practical applications would be suggested in the future.
