The necessity of improving manning standards in the Ship Officer's Act has recently been strongly advocated by the fisheries industry. The fisheries industry maintained the position of the relaxation cf current manning standards. However, the Labor unions, Marine Officers Association, and Radio Officers' Association persisted to strengthen the standards or to keep the current standards. This paper studies the appropriateness of current manning standards and proposes its improvement scheme to secure the safe operation of vessels.

지금까지 해양사고 관련 조사보고서와 연구결과를 살펴보면 선박승무원의 피로가 업무수행능력에 밀접하게 영향을 미쳐서 인간과실을 유발하게하고 결국 각종 해양사고가 발생한다는 사실을 확인할 수 있다. 본 논문에서는 해양사고와 선박승무원의 피로도와 인과관계를 파악하고 분석하기위한 국내외 관련 연구동향 및 그 결과들에 대한 고찰을 하고자 하였다. 이를 기반으로 향후 선박승무원의 피로도를 관리하고 완하할 수 있는 체계적이고 합리적인 방안을 마련하고 최종적으로 충돌, 좌초 등과 같은 각종 해양사고를 예방하는데 기여하고자 한다.

IMO에서는 피로(Fatigue)를 정신력, 체력, 신속성, 반응시간, 기능의 조화, 의사결정, 마음의 안정 등을 포함한 모든 육체적, 정신적 또는 감정적인 소모의 결과로 인하여 인간의 육체적 또는 정신적 능력이 저하되는 것 즉, 인간의 효율성의 감소라고 정의하고 있다. 선박승무원의 피로는 선박안전운항과 해양환경보호를 위한 업무수행능력(Performance)에 영향을 미칠 뿐만 아니라 승선중인 선박승무원의 건강(Health)과도 밀접한 관계가 있으며 또한 많은 영향을 미치게 된다. 본 연구에서는 선박승무원의 피로에 영향을 미치는 다양한 요인과 그로 인한 효과들을 살펴보고 피로와 선박승무원의 건강과의 관련성 및 그 영향 등에 대하여 고찰을 하고자 한다.

본 연구는 'KTX 여승무원 사건'을 통해 위장도급에 대한 노동부 법적 판단의 문제점을 분석한 것이다. 노동부는 이 사건에 대한 두 차례의 조사결과(2005, 2006) 당시 한국철도공사와 (주)한국철도유통이 체결한 'KTX 고객서비스 위탁 협약'이 적법한 도급에 해당한다고 발표했다. 그러나 실제 노동을 제공한 KTX여승무원 등에 대한 면접조사와 관련 사건자료를 바탕으로 한 분석결과에 따르면 위와 같은 노동부의 판단은 여러 가지 문제가 존재한다. 이에 본 연구에서는 위장도급에 대한 노동부 법적 판단의 문제점을 지적한 후, 이 사건 업무위탁이 사실상 '위장도급'에 해당하며, 한국철도공사 사업의 성격 및 지금까지 수행해온 여승무원 업무의 본질상 승무업무를 담당하는 근로자를 간접고용 하는 것은 사실상 적법한 한도 내에서는 어려운 일임을 밝히고자 했다.

This study analyzes how deep acting and surface acting, both classified as emotional labor, influence emotional exhaustion and turnover-intention for 263 KTX attendants. The followings are the summarized results of our analysis. First, the deep acting of KTX attendants does not affect emotional exhaustion, but surface acting was found to have a positive influence on emotional exhaustion. Second, the deep acting of KTX attendants had a positive impact on turnover-intention, but surface acting did not affect turnover-intention. Last, the emotional exhaustion of KTX attendants had a positive impact on turnover-intention. In conclusion, these results imply that it is important for employers to manage their employees' emotion in order to prevent turnover among KTX attendants.

Crew rostering in railway operations is usually done by arranging a crew diagram in accordance with working standards every month. This study was done to identify the problems related to the creation of crew rosters in railway operations and to suggest an optimum crew rostering method that can be applied in railway operations planning. To do this, the work standards of a railway company were identified, and a genetic algorithm was used to develop an optimal roster with equal working time while considering actual working patterns. The optimization process is composed of analysis of the input data, creation of work patterns, creation of a solution, and optimization steps. To verify the method, the roster derived from the proposed process was compared with a manually created roster. The results of the study could be used to reduce the deviation of business hours when generating a roster because the standard deviation of working time is the objective function.

Methods based on integer programming have been shown to be very effective in solving various crew pairing optimization problems. However, their applicability is limited to problems with linear constraints and objective functions. Also, those methods often require an unacceptable amount of time and/or memory resources given problems of larger scale. Heuristic methods such as neighborhood search, on the other hand, can handle large-scaled problems without too much difficulty and can be applied to problems having any form of objective functions and constraints. However, neighborhood search often gets stuck at local optima when faced with complex search spaces. This paper presents ,i hybrid algorithm of neighborhood search and integer programming, which nicely combines the advantages of both methods. The hybrid algorithm has been successfully tested on a large-scaled crew pairing optimization problem for a real subway line.

The Buddhist dance, which is considered to be the essence of Korean folk dance, has changed and developed over many years, having profound influential relations with Buddhism in terms of its origin, source, title, and costumes. Today the Buddhist dance is performed in two fixed types, Jangsam dance and Buk dance, but it is estimated that there must have been various forms of Buddhist dance during the Japanese rule based on the its historicity and various origination theories. It was around 1940 that Jang Yang-seon, the master of Haejugwonbeon, turned 'Seungininsangmu' into a work through Yang So-woon. The present study analyzed the video of 'Seungininsangmu' performed at the 'Performance in the Memory of Yang So-woon' in 2010, and the analysis results were as follows: first, the dance has a clear message to be delivered in its title and connotes an origination theory of Buddhist dance, which argues that the Buddhist dance was created by a Buddhist that underwent agony and corruption during his ascetic practice and later returned to Buddhism. Secondly, the process of Jangsam dance - Buknori - Bara dance - Heoteun dance - Hoisimgok - Guiui shows the thematic consciousness of the dance clearly in a sequential manner. Finally, the dance was in a form of combining various expressive methods according to the story and its development including the Bara dance, a dance performed in a Buddhist ceremony, the Heoteun dance, which is strongly characterized by individuality and spontaneity that are folk features, and Hoisimgok, the Buddhist music. Those findings indicate that the dance reflected well the flow of putting the Buddhist dance on the stage or turning it into a work in the early 20th century. Compared with the types of Buddhist dance in a strong form including the Jangsam dance and Buk dance, 'Seungininsangmu' conveys the meanings that the original Buddhist dance tried to express in terms of content and reflects on the diversity of combined Akgamu and theatrical elements in terms of form. The present study is significant in that it offers many implications for the Buddhist dance capable of future-oriented development.
