The advent of the era of data age and advances inartificial intelligence technology has led to innovations in various business areas. In particular, many attempts have been made to improve the stability of the marine accident, which has not previously been applied by a data-drive approach. Most of the marine accidents happen at a time when the vessel isapproaching a port and preparing for berthing. Although the cause of the accident has many factors, it is often caused by the difficulties of communication between the ship navigator and the control center. In particular, communication in English makes difficulties for navigators, not English astheir first language. To do this, proper English conversation education forsailors is very important. In order to support the issue, this study presents data and framework for the development of a chatbot for ship safety education.

연안선은 국제항해 선박에 비해 상대적으로 사고의 위험성은 높으나 이에 대응할 훈련기반이 취약하다. 본 연구에서는 연안선의 화재 및 퇴선상황에서의 승무원의 행동특성을 모델링하고 연안선 환경과 특성에 맞는 CBT용 훈련 프로그램을 개발함으로써 비상시 연안선 승무원의 사고대응 능력을 제고하고자 한다. 특히 이를 위해 연안 여객선에서 여객 대피를 위해 필요한 요소를 검토하여 개선점을 파악하여 프로그램 개발에 반영하고자 한다.

Eco-friendly architecture, generally speaking, is considered as the activity of planting more and designing ponds, therefore many clients and constructors prefer to avoid building so due to initial construction costs. This paper aims to examine the cognition of environmental equipment systems and the applicability of echo-friendly building constructions. We examined the designer's demands of building equipment systems and eco-friendly environment and tried to deduce desirable suggestions for the system. We should solve the fundamentals of economical problems in the construction of eco-friendly buildings and we better think that government should make it a policy to advertise it and to reform the taxation system regarding environment friendly buildings.

마이크로 크기 상업용 칠 분말의 반응성 향상을 위한 변수로 포기 반응 조건인 pH 조절과 산 세척을 통한 철 분말의 표면처리를 선정하고 질산성 질소를 처리대상오염 물질로 선택하여 철 분말에 의한 질산성 질소 처리 실험을 수행하였다. 산을 이용한 초기 pH조절에 의한 반응성 향상 실험에서 가장 좋은 pH 조절제는 염산이었으며 critical pH는 2 였고 산 세척에 의한 반응성 향상 실험에서는 산 세척한 철 분말의 반응성이 그렇지 않은 철 분말보다 현저하게 좋았으며 황산의 세척능이 염산보다 더 뛰어남을 알 수 있었다. 본 연구를 통하여 초기 반응조건의 조절과 철 분말의 산 세 척을 통한 전처리로 기존의 마이크로 크기 상업용 철 분말이 지닌 반응성의 향상을 꾀하였으며 수중의 질산성 질소 처리실험을 통하여 최적의 반응조건을 확립하였다.

In this research, effects of water circulation on phosphorus release from sediment into water body were studied. Sediments sampled at the Daechung Lake were used for the column experiments with circulation and non-circulation conditions. Deaeration coefficient, $K_1$ and reaeration coefficient, $K_2$ of non-circulation condition were 0.133 and 0, respectively, while $K_1$ and $K_2$ for circulation condition were 0.46 and 0.018, respectively. Oxidation Reduction Potential (ORP) showed a linear relationship with dissolved oxygen (DO) when DO is over 2 mg/L. Phosphorus concentration induced by phosphorus release from sediment was highly dependent upon DO, ORP, and pH. Under anaerobic condition, phosphorus release rate was higher for $Fe^{2+}$-bounded phosphorus compared to that of $Ca^{2+}$-bounded phosphorus.

The purpose of this study is comprehension for relationships between job stress and mental health for dental technicians in performing their duties. and this study can make use of opportunity of accumulation of data on dental technician's health care and work environment in future. Job stress for dental technicians served in general hospital dental laboratory were more highly effected than in local dental laboratory. and this result was statistically reliable. There were no meaningful differences in mental health between dental technician in dental laboratory in dental climic dental laboratory and commercial dental laboratory. and this result was not statistically reliable. The analysis of this study could be used by preliminary data to further research of relationships between job stress and mental health for dental technicians in the future. This study was made progress partially under limited members of dental technician in Seoul. so future studies are suggested that the more advanced total figure study for whole dental technicians in Korea.

The purpose of this study was to analyze the problems of the existing interior architecture connection qualification and propose the desirable direction of development. To do this, this study suggested basic materials for the connection between the qualification for interior architecture and practical business, and for an efficient qualification. For methods, first, this study analyzed the flow and the ratio of successful applicants of the qualification of interior architecture in order to consider problems. Secondly, this study grasped the composition of examination. Thirdly, this study examined the changes of the questions in standards. Fourth, this study investigated overseas examples. In addition, this study conducted a questionnaire for professionals engaging in practical business in order to contribute for establishing the desirable frame of qualification of interior architecture through the analysis and comparison of the results.

The feeding ecology of Doederleinia berycoides from the southern sea of Korea was examined. Specimens were caught monthly from January 2007 to June 2008. The size of the specimens ranged from 6.8 to 39.8cm in total length (TL). The primary prey items of D. berycoides included fishes and shrimps. In autumn, feeding mainly crustacea and fishes feeding mainly in winter. The individuals of smallest size class (less than 15 cm TL) fed mainly on crustacea. The proportion of crustacea decreased as body size increased, whereas the consumption of fishes increased. Fishes accounted for almost (86%) stomach contents of larger individuals (more than 35 cm TL).

The purpose of this study is to discover the interrelationship between modern costumes and Seung-Hee Choi's dancing costumes in 1930s. Seung-Hee Choi, who was a dancing pioneer in Korea, introduced the modern dancing costumes for the first time in Korea. The results are as followed ; First, we can find Eroticism in Choi's dancing dress. Choi's dancing costume had used gold thread, silver thread, spangle, see-through and a half-naked body clothing that decorated with beads and cords. It is similar to modern costumes in ubjet mtter, silhouette, design, and so on. Second, the influence of Futurism was in her dancing costumes, that is, it represented asymmetry designs and rectilineal figures. Third, not only beauty but also a Functionalism was expressed in her dancing costumes. Functional beauty was shown through bias cut, pleats, slit, and so on.
