Authors have investigated the monthly distribution of vibrio flora in sea water, mud, fish and shellfish in the public beaches at the suburbs of Busan in order to determine the possible origins of food poisoning. The results are summarized as follows: 1. The monthly distribution shows that V. parahaemolyticus occurs from May to November and V. alginelyticus all the year round. 2. A total of 40 strains of Vibrio flora were isolated from 40 sea water samples, 25 strains from 40 mud samples, If strains from 88 shellfish samples, and 3 strains from 30 fish samples. 3. More strains were isolated from the samples collected at Yongho and Suyeong that at the other localities. 4. A total of 80 strains of Vibrio flora, isolated from 198 samples, were divided into two groups : V. perahaemolyticus with 20 strains and V. alginelyticus 60 strains.

For the rip current warning system to reduce rip-current accidents, the implementation method producing the risk index was modified. To produce fast response from the warning system based on real-time observations, the method employed the numerical results (i.e., rip current likelihoods according to the possible scenario) obtained in advance. In this study, instead of using the empirical curve-fitting functions of the previous method, the present modification utilized two-dimensional distributions (i.e., wave height and period, wave height and tidal elevation, wave height and direction, wave height and spreading of frequency-directional spectrum) of rip current likelihoods stacked in a database of the system. The wave and tidal observations in 2021 at the Haeundae coast were applied to the modified system, and its performances at several real events recorded in CCTV images were presented.

As the power and scale of typhoons are growing due to global warming and socioeconomic damages induced by super-typhoons are increasing, it is important to estimate inundation damages and to prepare proper adaptation plans against an attack of the super-typhoon. In this paper, we estimated the inundation damages of urban area around Haeundae beach induced by super-typhoons which follow the route of Typhoon Maemi with the conditions of Typhoon Vera (Ise Bay in Japan, 1959), Typhoon Durian (Philippine, 2006) and Hurricane Katrina (New Oleans in U.S.A, 2005). The coastal area around the Haeundae beach (Busan and Gyeongnam province) is expectedly damaged by severe storm surges. In this study we calculated the rise of sea level height after harmonizing the different datum levels of land and ocean and estimated the inundation depth, inundation area and the amount of building damages by using airborne LiDAR data and GIS spatial analysis techniques more accurately and quantitatively. As many researchers are predicting that super-typhoon of overwhelming power will occur around the Korean peninsula in the near future, the results of this study are expected to contribute to producing coastal inundation map and evacuation planning.

Recently, traffic congestion has become serious due to increase of private car usages. Carsharing or other innovative public transportation systems were developed to alleviate traffic congestion and carbon emissions. These measures can make the traffic environment more comfortable, and efficient. Cloud Transportation System (CTS) is a recent carsharing model. User can rent an electronic vehicles with various traffic information through the CTS. In this study, a concept, vision and scenarios of CTS are introduced. And, authors analyzed the location of CTS rental stations and estimated CTS demands. Firstly, we analyze the number of the population, employees, students and traffic volume in study areas. Secondly, the frequency and utilization time are examined. Demand for CTS in each traffic zone was estimated. Lastly, the CTS rental station location is determined based on the analyzed data of the study areas. Evaluation standard of the determined location includes accessibility and density of population. And, the number of vehicles and that of parking zone at the rental station are estimated. The result suggests that Haewoondae Square parking lot would be assigned 11 vehicles and 14.23 parking spaces and that Dongbac parking lot be assigned 7.9 vehicles and 10.29 parking spaces. Further study requires additional real-time data for CTS to increase accuracy of the demand estimation. And network design would be developed for redistribution of vehicles.

The purpose of this study was to investigate the furniture use pattern and needs for built-in furniture of apartment residents. The subjects were 289 housewives who live in apartment houses in Haeundae, Busan. The size of apartments was 60 $m^2$ or 85 $m^2$.The self-administered questionnaire was used. There was no any furniture pattern which can be categorized as the specific one. That is, each family has different kinds of furniture pattern in living room and master bedroom. Also, some subjects wanted to have builted-in furniture in master bedroom.

The purpose of the study was to investigate the relationships among leadership, organizational commitment and management performance of restaurant workers from the Busan Haeundae area. Normally, each leadership type(transactional leadership, transformational leadership, servant leadership) effected organizational commitment and management result. For the field test and verification, 200 staffs of the Haeundae restaurant participated in the survey from April 1st to May 30th, 2017. The research result was summarized as follows. First, all leadership types(transformational leadership, transformational leadership, servant leadership) of Haeundae restaurant staffs had a positive impact on affective involvement. Second, transformational leadership and transactional leadership of restaurant staffs had a positive influence on continuous commitment. Lastly, continuous commitment of restaurant staffs in Haeundae affected management result. In conclusion, precedent study explained only hotel investigation.

The purpose of the study was to examine the socio-psychological factors of outdoor spaces in apartment complex. The data for the empirical analysis were collected from 412 households living in Haeundae New Town, Busan, and analyzed using descriptive statistics, factor analysis, and one-way analysis of variance and Duncan's multiple range test. The socio-psychological factors abstracted were territoriality, privacy, safety, sociality, accessibility, and identity. It was found that the households were generally positive to the overall socio-psycological factors in the current apartment complex. The significant explanatory variables for the responses to the socio-psychological factors were age of the wife, education of the wife, occupation of the wife, tenure type, monthly household income, length of residence, and overall satisfaction with outdoor spaces.

경제발전과 삶의 질 향상에 더불어 건축기술의 발전은 전 세계적으로 건축물의 고층화 대형화 용도의 복잡화 다양화를 가져오게 되었다. 하지만 미국의 WTC 테러 및 국내의 부산 해운대 우신골드스위트 화재처럼 대형 복합건축물의 화재는 인명 및 재산피해 뿐만 아니라 국민의 사회적 불안감을 증대시키고 국가 신뢰도를 실추시키는 원인이 된다. 따라서 건축설계 단계에서부터 재실자들의 안전한 피난을 위한 피난설계가 중시되어야 한다. 본 연구에서는 국내 피난관련 사항의 체계와 특징을 살펴보고, 선진국의 피난관련 사항과 비교 검토를 통해 문제점을 파악하여 국내 실정에 적합한 피난설계를 제안하고자 한다.

최근 국내 대도시를 중심으로 초고층건축물이 계획 건립되고 있으며, 그에 따라 국내 외적으로 초고층건축물 화재가 빈번하게 발생하고 있으나, 현재 국내 소방기술은 그에 대한 어떤 확실한 대안도 갖고 있지 못하다. 2010년 발생한 부산 해운대 우신골든스위트 화재사례를 통해 고층건물 화재진압의 부진했던 주된 원인과 문제점이 분석되면서, 최근 국내 고층건축물의 화재를 대비한 관련법(건축법, 소방법 등)들이 제정되고 있다. 그러나 아직도 고층건축물에서의 화재진압방법, 인명구조 및 소방진압장비의 연구 개발의 성과가 부족하다. 본 연구에서는 초고층건축물의 외장재를 통한 수직화재 확산방지를 위한 보다 효과적인 진압방법과 인명구조방법을 제안하고자 한다.

최근 발생한 부산 해운대 화재 이후 피난 활동이 제한적인 고층 건축물의 화재 안전에 대한 관심이 증대되고 있다. 그러나 현행 규정은 50층 이상의 초고층 건축물을 대상으로 하고 있으며 상대적으로 준 초고층 건축물에 대한 제도적 기반과 연구가 미비한 실정이다. 따라서 본 연구에서는 지하연계복합건축물에 관한 피난 안전구역면적 산정 기준에 대한 적용성을 분석하고자 국외의 관련 기준과 비교 분석하였다. 그 결과, 수용 인원에 관한 기준은 홍콩, 한국, 싱가포르, 중국 순으로 강화 적용하고 있으며 피난안전구역의 면적은 싱가포르의 경우 전체 수용 인원의 50% 이상과 1명당 $0.3m^2$을 전제로 하는 피난안전구역의 면적 기준이 국내의 각 층별 1/10의 면적의 합과 동일한 것으로 분석되었다.
