In Korea, the System of search and rescue in water have came into force on the basis of the Korea Life Saving and Rescue Act. 1961. But It's a premodern administration law which is not fit for an international system of the search and rescue and become disconnected with reality in Korea. Recently the marine casualties occur frequently in Korea coastal area, therefore, we need to amend the 1961 Act. The amendment which is carried out by the Korea Maritime Police Agency is a provision to receive International convention(SAR, 1979). The amendment of this Act will give a epoch-making change to Korean policy of the life-saving and rescue, security to marine safety and contribution to National positon on system of "Search and Rescue". In this thesis, I propose a development scheme to be conductive to original task on "Search and Rescue" of International Convention in Korea Life Saving and Rescue Act(Amendment, 1994).t(Amendment, 1994).

A new shell divider was manufactured according to the principle of the lever in order to improve working efficiency in collecting the gonad of Sea Urchin, Anthocidaris crassispina, around the coast of jeju. It was composed of three parts of a pair of handles for grasping power, a fulcrum and a pair of knives for action with 21cm in length and 13cm in width. The operating efficiency of the shell divider was tested out in three place of Jeju coast. Statistical significances of differences of working time between test groups were calculated according to the t-test with the level of significance. In dividing the shell of sea urchin, the average of about 3 seconds of working time by the shell divider was less than that by a knife. At the result of t-test, the statistical significance in the working time existed between the divider group and the knife group. On the other hand, the working time among the divider operators showed no significant differences. It is concluded that the shell divider is more efficient than a knife in traditional operating.

An acoustic and trawl pilot survey using a small vessel was conducted in Jinhae bay of the South Sea of South Korea on April 13~14, May 11~13 and June 8~10, 2015. During the survey, acoustic data was collected and bottom trawls were conducted at the same time. First, various noises were eliminated by using the Park method based on the Wang method (Wang et al., 2015; Park et al., 2015), the species compositions and catch rate from each bottom trawl were observed, and spatial distribution of fishery resources in the water column and their nautical area scattering coefficient (NASC) were investigated through acoustic data. During the entire survey period, 12 orders, 33 families and 41 species were caught. The most caught species in April, May and June were Okamejei kenojei, Zoarces gilli and Pholis nebulosa, respectively. Fish schools were observed near the line of net mouth height in April. Numerous weak scatters were presented on the echograms in May and June. Many fish schools appeared in between the water surface and 20 m deep in May. The NASC value from entire water columns was the lowest in April ($35.9m^2/n{\cdot}mile^2$) and highest in June ($1541.3m^2/n{\cdot}mile^2$).

Decoys for automatic jigging machines, the body part of a squid hook, have been developed in small and existing sizes in consideration of squid food, color blindness, and retinomotor responses and in utilization of pearl pigment, PP of high transparency, and combined mixture. In comparison of the developed silver-white decoy and existing decoys, the optical characteristics were examined, and the fishing performance of small size silver-white squid hooks was assessed in application of 4 fishing boats with the squid automatic jigging machine and metal halide fishing lamp in July, 2012. The luminances of the three squid hook colors-green, dark green and silver-white-increased as the intensity of illumination increased. Among these, the increase of silver-white was particularly distinguished. As to the average contrast of squid hooks, that of silver-white was 10.33, which was the highest, and then green 1.86 and dark green -0.10 in the order. As to the fishing performance of the silver-white hook, that of the 202 Geumyeong-ho and 101Yongjin-ho which caught squids were similar to that of the existing green hook and was relatively low in the case of the Dongbu-ho. However, that of the Haengbok-ho which caught relatively small squids whose average length was 19.9cm and installed silver-white hook in all automatic jigging machines was significantly excellent. In order to enhance the fishing performance of small size silver-white hooks, therefore, it would be effective to install in every automatic jigging machines of fishing boat and to start fishing before July by which small squids are caught.

At the first time in South Korea, the state of the art acoustic systems were mounted on the R/V Tamgu 21. The acoustic systems are an EK80 broadband echosounder (18, 38, 70, 120, 200 and 333 kHz) which has two beam modes such as continuous wave (narrowband) and frequency modulation (broadband), an ME70 multibeam echosounder (70-120 kHz), and a SH90 sonar (111.5-115.5 kHz). Acoustic data from broadband mode have a very short range resolution, a large detection range, a high signal to noise ratio, and a wide and consecutive frequency response. In ME70, each individual beam consisted in a multibeam plays a role as a spilt beam. The first trial of the cutting edge acoustic system installed on the R/V Tamgu 21 was conducted from 15 Feb to 29 Feb 2016 in East Sea, South Sea and East China Sea. The properties of the acoustic systems were elucidated and exploratory results from three systems were exhibited. Lastly, issues which should be considered and future research plan are mentioned.

본 연구는 해양경찰조직의 사회자본과 직무만족 및 직무스트레스영향관계를 파악하였다. 이를 위하여 이론적인 논의 선행연구를 통하여 사회자본의 구성요인으로 신뢰, 참여, 네트워크 설정하였으며 직무만족과 직무스트레스를 하위변인으로 설정하였다. 분석결과를 살펴보면 다음과 같다. 첫째, 해양경찰공무원의 사회자본과 직무만족도가 높으나 직무스트레스는 낮은 것으로 조사되었다. 둘째, 해양경찰공무원들의 사회자본이 직무만족에 정적인 영향을 미치며, 구체적으로 살펴보면 신뢰, 네트워크, 참여 순으로 직무만족에 영향력을 미친다. 셋째, 사회자본과 직무스트레스관계를 살펴보면 참여는 직무스트레스를 감소시키나, 네트워크는 오히려 직무스트레스를 증가시키는 원인인 것으로 조사되었다. 이러한 조사를 근거로 해양경찰은 구성원의 직무만족과 스트레스에 영향을 미치는 사회자본을 구축할 필요가 있다.

본 연구는 신임해양경찰공무원을 대상으로 성격과 보상이 PSM에 영향을 미치는가에 대하여 연구한 결과 첫째, 성격 요인의 하위변인 중 신경성은 PSM의 하위변인인 공공정책 호감도와 공익몰입, 동정심에 영향을 미쳤다. 또한, 성격 요인의 하위요인 중 외향성 요인은 PSM의 하위변인 중 자기희생에만 영향을 미쳤다. 둘째, 보상 요인은 대부분 PSM에 영향을 미치지 않는 것으로 나타났고 이중 내적 보상은 PSM 하위변인 중 동정심에 영향을 미치는 것으로 분석되었다. 이러한 연구를 기반으로 성격 요인이 공공봉사 동기에 영향을 미치는 요인임이 확인된 결과 채용에서 반영할 수 있는 제도적인 개선이 필요하며 보상과 공공봉사 동기와의 관계를 검증하기 위한 연구의 필요성이 제기된다.

최근 군사용에서 산업용으로 확대되고 있는 4차 산업 기술 중 하나인 드론은 경찰청의 수색 임무에서 적극적으로 활용되고 실종자를 발견함으로써 광범위한 지역에 관한 관심과 대규모의 수색 인력의 투입을 감소시키고 있다. 그러나 경찰의 드론 운용의 법률적 검토가 지속적으로 필요하고 관련 운영에 대한 시스템의 고도화와 수색기법과 연계된 촬영 이미지 분석의 중요성도 동시에 증가하고 있다. 본 연구에서는 정밀 수색 및 모니터링 개념에서 기록, 보존, 모니터링이 원활하기 위해서는 영상 데이터 기반의 수색이 아닌 사진 기반으로 공간정보를 구축하여 정밀 수색이 수행되면 효율성이 높고 골든타임 확보가 가능하다. 따라서 피사체의 크기에 따라 불필요한 공간정보 완성률을 조절하여 결과 데이터 용량을 감소시키는 공간정보 구축 기법을 제안하고자 한다. 이를 통해 대규모 지역에 대한 드론 수색 임무의 활용 범위를 고도화하고 경찰 수색의 드론 운용 매뉴얼 구축을 위한 기초자료로 활용하고자 한다.

Precedent research and development of personal armor and anti-stab wearing system has been conducted since 2018 as a part of the government-affiliated cooperative development project to create the best utilization of present technology and achievement according to the civil and military technical cooperation project promotion law. At present, the armor system operated by the ROK(Republic of Korea) military, the police, and the marine police is utilizing only basic armor using armor vests and plates. Therefore it is necessary to develop the personal armor and anti-stab wearing system which is suitable for various tasks in army with maximum protection capability. In this paper, we analyzed the study about international technologies, market trends of the developed countries and scope of research, utilization plan, R&D results for the best armor and anti-stab wearing system development.
