We analyzed the questionnaire survey for the current maintenance of Incheon port's loading and unloading equipments and the possibility of TPM(Total Productive Maintenance) application. And also, We certificated Structural Equation Model with computer packages. Results of the survey indicated that the current maintenance of Incheon port's loading and unloading equipments was not good. We recognized the relationship of contextual factors about the productivity of the loading and unloading equipments The productivity of the loading and unloading equipment positively depends on maintenance management of equipments, but the organization and personnel management does not have a influence on the productivity of the loading and unloading equipment. So we suggest TPM as the future maintenance methodology of equipments. Using TPM to the loading and unloading equipments, we will try to improve the methodology of the organization and personnel management.

The aim of this study was to examine the scale and market share of Chinese's research facility & equipment in the domestic research equipment market of basic and analytical science field for analyzing the difference of the number and amount of construction by year of acquisition, national research facility equipment standard classification code, and type of institution based on the information of the research equipment invested by the Korean government for the past 14 years. In addition, we analyzed the correlation among the year of acquisition, equipment standard classification code, and type of institution variables. As of January 1 2019, from 2005 to 2018, 50 Chinese's research facilities & equipments (main equipment with a construction cost of 30 million won or more) built in the basic and analytical science fields were selected for this study and their number of construction, amount of construction, year of acquisition, type of institution, and standard classification code were analyzed. Differences of the number and amount of construction with-in and by year of acquisition, standard classification code, and type of institution were tested using a single sample Chi-square test, Mann-Whitney U test, and Kruskal-wallis test. The correlation among the three variables was analyzed by using the Chi-square test of cross-tabulation analysis. And there was a statistically significant correlation among the year of acquisition, standard classification code, and type of institution (p<.05). Compared to the 2000s, in the 2010s, high-priced Optical Electronics/Video Equipment was installed at private universities, private enterprises, and government-affiliated research institute. Therefore, the domestic construction status of Chinese's research facility & equipment in the basic science and analytical science field is less than that of the domestic ones, but the number and the amount of construction are increasing statistically. So it is necessary for the government to be able to recognize the possibility that the Chinese's research facility and equipment can encroach on the domestic research industry market and to prepare related provision.

민방위대 창설 이후 50여 년 동안 민방위 전반적인 분야에 많은 변화가 있었다. 민방위 분야의 주요 업무는 전시상황 및 대규모 재난상황 대비업무로 비상사태 시 국민을 보호하고, 전시 지원 업무를 수행하는 포괄적 안보 개념으로 확대된다. 그러나 1975년 민방위대 창설 50여 년간 누적된 민방위 임무 역할 변화와 복합화로 민방위 장비 운용의 효율성이 상실되고 민방위 역량을 초과하는 법적 임무 설정 등으로 현재 운영 장비의 실효성에 논란이 일고 있다. 복잡하고 다종다양한 민방위 장비 체제로는 전·평시 실제적 재난현장에서 통합 역량을 발휘하기에 제한이 있고 민방위대별 민방위 장비 보급기준이 상이하고 보급기준에 따른 임무 수행 가능 범위도 모호하여 실질적인 효과를 발휘하기도 어려운 실정이다. 본 연구는 최적·최소 임무를 기반으로 한 민방위대 편성, 교육과 장비 운용 체제를 통합 일치시킨 새로운 민방위 장비 운용체계 정립의 기초연구로써 민방위대 필수장비 선정을 위하여 재난유형별 임무를 분석하고 장비를 조사하였다.
