The high wind wave alert has a great impact on ships and maritime service workers navigating in the vicinity of Korea. This study aims to evaluate the appropriateness of the high wind wave alert by comparing and analyzing the observation data of major marine meteorological buoys with the high wind wave alerts in the coastal sea and offshore of the West Sea, South Sea, and the East Sea announced by the Korea Meteorological Administration for the past 11 years(2010-2020). As a result of comparing the daily, monthly, and annual statistics of the high wind wave alert and marine meteorological buoy observation data for each sea area by annual, monthly, and seasonal average, the accuracy of high wind wave alerts was very low across the entire sea area. In particular, it was analyzed that the accuracy in the coastal sea of the South Sea and Jejudo was the lowest in winter. It was confirmed that the accuracy of marine weather forecasts and alerts needs to be improved when considering the effects of the high wind wave alerts on fishing vessels, passenger ships operations and tourism, and marine leisure activities.

In the past, waves, which are the main external forces acting on marine and coastal structures, have been dealt with only in terms of safety. Recently, various studies have been conducted to define the characteristics of waves in a specific area in order to respond to the increasing demand for diversified marine activities such as ocean energy development and marine leisure sports. Although the characteristics of waves are specific to the site, the available spectrum model proposed in previous studies are limited. In this study, we analyzed the shape of the ocean wave spectrum by comparing it with the standard spectrum model.

The purpose of this study is the Influence of Sailing Yacht Experiences Participants of Flow on Satisfaction and Self-esteem relates to the impact on leisure industry, the popularity of korean culture and yacht basis for the realization is to provide. To achieve this study, Busan, Ulsan, Gyeongnam area residents to target marine leisure and marine leisure experiences Academy experienced subjects participated in a total population of 428 people selected for the survey was conducted, data processing method frequency analysis, reliability analysis, validity analysis, a simple regression analysis, multiple regression analysis was used. Than as a result of research methods and data analysis through the conclusions are as follows. First, sailing yacht experience the flow degree of the participants to influence satisfaction were static. Second, the flow degree of the participants experienced sailing yacht self-esteem(general factors, family factors, work factors, social factors) was found to affect the static. Third, sailing yacht experience satisfaction self-esteem of the participants(general factor, family factors, work factors, social factors) was found to affect the static.

In this study, We analyzed whether the quality of marine leisure sports experience have effects on participants satisfaction, immersion and 5motive for reparticipation. We also investigated effect of participants' pre-experience of participating race on satisfaction, immersion and motive for reparticipation. Sense of freedom and social interaction appeared to affect satisfaction of participants significantly, but the sense of control did not. Sense of freedom had effect on immersion, whereas sense of control and social interaction had no effect on immersion. Significant relationship between motive for reparticiaption and participants' satisfaction and immersion was observed. Interaction effect between participant's satisfaction and was significant. Immersion mediates relation between reparticiaption and participants' satisfaction, participants experienced yahct race before showed more effect of satisfaction on motive for reparticiaption than participants with no race experience, who showed no significant effect of satisfaction on motive for reparticiaption. Immersion have effect on motive for reparicipation in both groups, but effect size was greater in the group with race experience. Thus, satisfaction and immersion of participants who have pre-experience of participating race showed greater effect on reparticipation than who haven't.

요즘 잊을만하면 한번씩 발생하는 다양한 해양 사고를 뉴스에서 접할 수 있다. 이는 해양에서 물적, 인적 이동이 증가하고 있으며 다양한 레저활동까지 해상으로 확장되고 있기 때문이다. 본 논문은 해양 사고 발생시 사후 처리에 활용되는 방식에 대해 제안하고 있다. 기존에는 해양 사고가 발생하면 사고에 대한 분석을 위해 VTS 시스템의 녹화재생 기능을 가장 빈번하게 사용하였다. 기존 VTS 시스템의 녹화재생 방식을 이용한 사고 발생 시각 및 피의 선박 확인은 많은 사간이 소요되어 물적, 인적 자원이 많이 필요한 문제점이 있었다. 특히 선박 기관 손상을 일으키는 어망 훼손 관련 사고와 같이 발생 사각을 정확히 알지 못하는 경우는 사고 발생 시각 분석에 많은 사간과 노력이 요구되었다. 제안하는 방식은 사고 발생 영역 및 특정 시간 조건에 대한 통항량 정보를 미리 추출하는 방식으로 단독 또는 기존의 녹화재생 방식과 함께 사용할 경우 사고 현황을 파악하는데 빠르고 효율적이다.

중국경제의 지속적인 성장에 따른 동북아지역의 해상물동량 증가, 국민의 삶의 질 향상에 따른 레저활동 인구 증가와 선원의 고령화, 외국인 선원증가 현상 등 해상환경의 변화에 의한 해양사고 발생 가능성은 커지고 있다. 이에 정부는 안전수준 향상을 위한 해상교통의 체계적인 안전관리시스템 고도화 정책을 추진하고 있다. 따라서 본 연구에서는 국내외 도로교통, 건설업 등 안전부문에서 시행하고 있는 평가제도의 사례를 조사 분석하여 해운선사의 안전등급제 도입을 위한 제도의 목적, 도입방법, 평가방법 등을 제시함으로써 효과적인 제도도입 및 운영방안을 제시하고자 하였다.

최근 국내에서는 경제적 여유와 함께 웰빙에 관심이 높아지며 도심생활에서 벗어나 수변공간, 해양레저활동 등이 주목받고 있다. 이에 따라 수상에서의 다양한 활동을 수용할 수 있는 플로팅 건축물에 대한 관심이 증가하고 있으며, 플로팅 건축물을 이용한 다양한 용도와 기능의 건축물들이 수상에 설치되고 있다. 플로팅 건축물 역시 사람들의 생활을 위한 공간으로 육상의 일반 건축물과 같이 쾌적한 거주환경 제공을 위하여 다양한 설비들이 설치되고 있다. 하지만 플로팅 건축물은 수상에 위치한 입지적 특성으로 인하여 육상의 일반건축물과 다른 환경적 요인을 고려한 설비시스템 도입이 필요함에도 불구하고 수상환경을 고려한 설비시스템의 설치는 이루어지지 않고 있다. 특히, 실내의 쾌적한 거주환경 유지를 위하여 중요한 요소인 냉난방설비는 충분한 성능을 발휘하기 위하여 시스템설계 전 충분한 환경적 요소를 고려한 부하산정이 필요하다. 따라서 본 연구에서는 플로팅 건축물의 입지적 특성을 고려하여 냉난방 시스템 설계 시 일반건축물에 적용되는 부하산정 요소 외 해수온도, 해수면 반사일사 및 창면적비를 부하산정 요소로 도입하고 각 요소별 특성을 고찰하여 플로팅 건축물 냉난방부하에 어떤 영향을 미치는지에 대하여 종합적으로 고찰하였다.

Recently, needs of recreational marine industry are consistently increasing due to increasing of income and pursuit on well-being. For these needs, central government and local governments have tried to build tens of marinas to meet demands and promote related industries. Therefore, need of smart pedestal system has also increased. However, domestic companies have not manufactured smart pedestal systems, so many pedestal systems have been imported from advanced countries such as England, Denmark, and Italy. This research has developed a smart pedestal system using IT convergence technology. This system is assembled by each several module which has its own function and board. Each module is not developed on an embedded OS. Instead, it has its customized operational software based on its kernel. Thus, this system brings about cost reduction of productions and maintenance.

Currently offshore fisheries are one of shrinking industries and fishermen are getting older. Moreover it is difficult to work fisheries for decreasing fishermen as the time goes. Two people per a boat work together at least for proper fisheries. If the unskilled fisherman boards on boat, it will make some troubles to speak each other and diminish the efficiency of working because one person should control the boat. So it need to study the remote control system for leasure and outboard engine that can control and work at the same time. The remote control system is consisted of engine, steering gear and forward reverse neutral gear controls. These three controls are made by position and speed control using DC motor, and microcontroller is used to control the engine speed and rudder angle. This system can be controled and worked alone and we tested the system at sea and confirmed that the system works properly.
