이 연구에서는 자원봉사센터의 지원체계와 운영체계에서 나타나는 문제점을 다각도로 분석하고 자원봉사 센터의 전문성 확보 및 활성화 방안을 도출하고자 한다. 자원봉사관리에 대한 운영 실태를 분석했을 때 현재 한국의 자원봉사센터 문제점은 다음과 같다. 먼저 자원봉사에 대한 체계적인 관리가 결여되어 있을 뿐 아니라 자원봉사단체간 의 협력적인 네트워크가 제대로 형성되어 있지 않아 관리의 효율성을 저하시키고 있다. 또한 자원봉사관리자의 전문성이 부족하고, 자원봉사관리자에 대한 교육과정이 미비하며 자원봉사단체에 대한 정부의 지원도 매우 열약한 실정이다. 본 연구자는 이러한 문제점을 해소하기 위하여 다음과 같은 개선방안을 제시하고자 한다. 첫째, 자원봉사 관련 조례제정과 제도적 지원이 필요하다. 둘째, 각 부처별 자원봉사센터가 효율적으로 운영되어야 한다. 셋째, 자원봉사 관리자의 전문성 강화가 필요하다. 넷째, 자원봉사자 관리를 효율적으로 할 수 있어야 한다. 다섯째, 프로그램 개발 기능 및 수요처 개발을 강화하고 센터와 지역사회의 관계 증진할 필요가 있다. 마지막으로 안정적인 예산확충과 자원봉사 전담인력 확보가 절실히 필요하다. 따라서 자원봉사센터 활성화를 위해서는 공공부문에서는 과감한 재정 및 제도적 뒷받침을 마련해 주어야 하며, 민간 부문에서는 자발적인 활동이 될 수 있도록 자율성을 최대한 보장해 주어야 한다.

This study aimed to analyze the profitability and economic feasibility of hairtail trolling line gear that was developed for the last 3 years (2015-2017). The new fishing gear technology development was accomplished to solve the current problem of fishermen shortage in hairtail targeting fisheries in Jeju region. Results indicated that the profitability of developed hairtail trolling line fishery was estimated to be 36.1 % which would be higher than that of other hairtail targeting fisheries in Jeju region. In addition, as an economic feasibility, the net present value and the internal rate of return of a 20-year cash inflow and outflow were evaluated to be 400.2 million won and 66.9 %, respectively. However, sensitivity analyses of main variables showed that the profitability and economic feasibility would be vulnerable to catch amount and market condition changes.

Fish exportation using airplanes incurs sizable logistics costs (12,000KRW/kg), according for more than 45% out of the total export cost. Thus, it is unreasonable to quantitatively expand fish exportation by means of air transport. In addition, cases of failing to deliver fish at the right time to the right place occurs frequently due to the limited cargo capacity and insufficient cargo space of airplanes, especially during the peak season. Therefor, a technology that not only minimizes the logistics costs but also transports fish freshly and safely, in the case of long distance exportation to countries such as the United States and Taiwan, should be developed. In this study, a live fish container control system for long distance transportation was designed and implemented. Live flatfish (2,000kg) were selected as the target fish, were transported to the United States to analyze and verify the performance of the a live fish container control system and transportation ability.

It is clearly understood that e-navigation is beneficial to prevent collision and grounding of ships. The purpose of this study is to define and present a future ship operation system under the e-navigation environment in order to provide clear direction for the design of Korean e-navigation system. The future ship operation system consists of shipboard navigational system, shore supporting system and maritime communication system. To achieve the objectives of this study, the ship operation system was discussed separately into SOLAS ships and non-SOLAS ships in this study. In SOLAS ships, mariners become a system manager, choosing system presets, interpreting system output, and monitoring vessel response. In small ships and fishing vessels, mariners may enjoy their navigation by using the automatic tracking of ship’s position on the portable electronic chart display. The improved bridge design, integrated and harmonized navigational system and single window reporting will reduce significantly the administrative and physical workload of mariners. Mariners can concentrate their attention more on navigational duty under the e-navigation environment. To build an effective Korean e-navigation system, the essential navigational functions and e-navigation services for small ships and fishing vessels must be identified and developed taking into account user needs.

For the sustainable development, companies are making a lot of efforts such as activities of sales increase and cost reduction. Among these, efforts to use limited resources efficiently and effectively is still being made steadily. And many methods for management innovation are being introduced and used. However there were partial or temporary effects only. So there are not enough to achieve operations performance to cover the entire system. Therefore, in order to maximize performance or to improve sustainability across the companies, it is necessary to rebuild the existing system with process perspective not with existing functional perspective. This study was performed to achieve the objective that is operation performance improvement of certification body. So literature review was researched and analyed about the process innovation and the process approach. And basic model which is compatible with ISO/IEC 17021 requirement for the certification body was established in this study. Based on this model, one of the certification body was selected and operation system for this organization was established, documented and implemented through the process approach method. In the result, operations performance of certification body on the side of efficiency and effectiveness is analyzed and the effect of reconstruction of system on operations performance was figu

Continued efforts to build up Safety Management System(SMS) and to improve its efficiency in airports, to which customers have direct access, are taken for granted due to continuous development of the aviation industry in both quantity and quality and rapid growth of air transportation market. This thesis proposed efficient operation methods of SMS for domestic airport organizations including Incheon International Airport(IIA), the largest airport in South Korea, aiming at strengthening aviation safety from the perspective of airport operators who play a pivotal role in service provider SMS. Those are consolidation of the existing safety management organizations and various improvements to promote voluntary incident reporting system. To draw a proposal for the improvements, conducted a research on domestic safety management status, carried out an analysis on operating conditions and did a research on ICAO regulations, domestic legal system as well as statistics data. Relevant studies and researches were also gathered and analyzed. A search for further improvements can also help increase operational efficiency and promoting a higher-level of safety awareness among operators can establish mature safety culture at airports.

Environmental pollution including air, land, and water has become one of the most critical issues in global interest. The damages due to environmental pollution lead to serious disasters. Nations have realized the importance of environment protection and have been starting to force organizations to implement environmental management system (EMS) as way of protecting environment. ISO 14001 requirements that are the most popular standard as EMS have been developed to support continuous improvement to environment management. It has been revised once since publication and ISO 14001 : 2004 version is currently available. Organizations globally started to acquire the certificate of EMS to observe environment related laws, accept customers’ and stakeholders’ request, increase market share, and fulfill implementation motives. This article examines the audit data that were collected for several years from manufacturing companies including shipbuilding, machinery, metal, automobiles, and chemical companies in southeastern Korea on the basis of ISO 14001 : 2004 requirements. The audit data were classified into minor nonconformities based on factors such as business size, business type, and EMS implementation period. We conduct hypotheses test using statistical methods in order to see if there are any significant differences based on the factors. We draw conclusions for the results of hypotheses test and address the necessities of energy, greenhouse gas, green management, and continuous improvement to enhance the efficiency of EMS implementation.
