  • 해양수산부는 2014. 4. 16. 발생한 세월호 전복사건 이후 안전관리 부실 문제가 제기되어 법과 제도를 강화하였다. 그럼에도 불구하고 내항 여객선에서는 최근 5년 동안 매년 평균 약 13건의 충돌·접촉·좌초사고 발생하고 있다. 특히 해양안전심판원의 재결에 따르면, 항내에서 조선 중 발생한 여객선 사고의 주된 원인은 대부분 선장의 부적절한 조선 또는 부주의라고 판단하였다. 이에 본 논문은 항내에서 발생한4건의 여객선 해양사고를 분석한 후 선장의 부적절한 조선 등 행위에 기여한 환경적·제도적·물적·인적 요인에 대해 상세히 살펴보았다. 그결과 다음과 같은 기여 요인들이 확인되었다. 첫째 환경적인 요인으로서 선회장의 크기가 기준을 충족하지 못한 사례가 확인되었다. 둘째 제도적인 요인으로서 VTS관제가 적절히 지원되지 않았고, 선장이 안전한 항내 조선을 위한 교육이 부족하며, 최신화된 해도가 제공되지 않았다. 셋째 물적요인으로서 선장이 Wing bridge에서 접·이안 조선 중 실시간으로 속력을 확인할 수 있는 속력계가 설치되어 있지 않았다. 그리고 인적요인으로서 선장이 적절한 선교자원을 지원받지 못하였고, 적절한 항해계획이 수립되지 않았다. 이에 본 논문에서는 선장의 안전한 항내 조선을 위해 기준에 맞는 선회장을 확보하는 것과 선장이 선박조종 시뮬레이션 교육을 이수하도록 하는 것 등을 개선방안으로 제시하였다.

  • The primary goal of this study is to define the future image of modern fashion. By review of many references, this study has examined predictable future in common, various researches on future, and futurism that appeared from art history. This study has also identified the trend of future image and the properties of the image in terms of fashion as well. The purpose of this study is defined as future image of modern fashion. First of all. through a large literature, this study is to examine general future and the study of future, to investigate futurism appears from art history. and to identify the trend of future image and the properties of the image in terms of fashion. The main results of this study include : 1) General future means forthcoming sometime or a state of life at that time, and future is not drawing near naturally in accordance with the passage of time. The future is developed according as which the owners of time have independent meaning and what they select. 2) The futurism had started with the background based on Darwins and Einsteins scientific theories and Bergsons and Nietzsches philosophical thoughts, which was then established by Marinettis Futurism Statement and Dynamism Theory of Umberto Boccionio, Giaomo Balla, Luigi Russolo and Gino Severini. As the purpose of futurism is to represent the dynamism of machinery and the beauty of speed, it has been developed toward op art and kinetic art including video art, laser art, and holography. 3) Fashion style and trend of futurism from the beginning of 20th century up to now can be defined as follows : Firstly futurism fashion represented by loud colors and geometric pattern appeared from 1910s to 1930s in the first place. Secondly, or art fashion and kinetic fashion appeared in 1960s due to the influence of op art and kinetic art which were developmental arts of futurism paintings. Space Look and Cosmo Corps Look that were designed by Andre Courreges, Pierre Cardin, Rudi Gernreich and Paco Rabanne, were also the trend of future image fashion. Thirdly, various materials and techniques developed this future image fashion in 1980s, and Glitter Look and Collage Look were its representative style. Fourthly, in 1990s, human beings dreamed the freedom of mind by human-oriented thought. and created the ecology of new concept mixed with technology due to anxiety on environmental destruction. which influenced on the advent of Zen style.

  • The purpose of this study was to provide the design guidelines for the activity spaces in the skilled nursing facilities for the elderly through the investigation of the spatial characteristics and using behavior The researcher interviewed the staff regarding programs in 15 facilities, investigated and observed the use of the spaces from 15th of December, 2004 to 19th of February, 2005. The programs in facilities were categorized into human knowledge, arts, music, exercise, recreation, cooking gardening, religious and social activities, and those were peformed once to 4 times a day. They were conducted in the elderly individual rooms, lounges, program rooms, dining room, or(and) auditorium. The results of the study were as follows: First, investigating the activity spaces, the lounges and elderly individual rooms were mostly on the same floor so that the elderly had no big trouble in access to the lounge. The program rooms of the facilities in suburban and rural area were on the same floor as the elderly individual rooms and they were likely to combine with another usage, compared to those On city were mostly separated from the residence floor. Most of dining rooms and auditorium were on the basement or on the 1st floor. Second, in the programs by the activity spaces, elderly individual room and the program room were used more for the human knowledge and art programs with small group. The lounges were for recreation and social activities with (both of) small or(and) big group and dining rooms were mainly used for cooking programs. In auditorium, recreation, religious and social activity were performed with big group. Third, the individual rooms for the elderly had more capacity if those did not have any beds, but often had a trouble in making a passage way. The lounges needed to remove decorations and displayed furniture obstructing the passages and to arrange both of the western and eastern type of tables for the efficient use of the spaces. It took a long time in preparation of the furniture and other equipment if the program room was with another usage.

  • Bifidobacterium longum subsp. longum BBMN68, isolated from centenarians in Guangxi, China, has been proved to be a promising probiotic strain for its health benefits. In this study, the biodistribution of this strain in the rat gut was first investigated using the quantitative realtime PCR assay and propidium monoazide. Strain-specific primers were originally designed based on the BBMN68 genome sequence. Healthy rats were orally inoculated with either a single dose of BBMN68 (1010 colony-forming units/kg), or with one dose per day for 7 days and bacterial concentrations were analyzed in detail from the intestinal contents and feces of four different gut locations, including stomach, small intestine, colon, and rectum. Results indicated that strain BBMN68 could overcome the rigors of passage through the upper gastrointestinal tract and transiently accumulate in the colon, even though survival in the stomach and small intestine was not high. A good level of BBMN8 could stay in vivo for 72 h following a 7-day oral administration, and a daily administration is suggested for a considerable and continuous population of BBMN68 to be maintained in the host intestine.
