2000년 9월에서 2003년 1월까지 부산 지하철역을 대상으로 CO, NO, $NO_2$ 그리고 $O_3$등 오염물질 4가지를 측정하고 그 결과를 계절별로 분석하여 요약하면, 봄에는 실내인 승강장에서 연산동역과 남포동역의 NO, $NO_2$ 농도가 높았다. 여름과 가을에는 연산동역의 승강장 $O_3$ 농도가 다른 역에 비해서 높은 것으로 나타났다. 겨울에는 다른 계절에 비해서 NO, $NO_2$는 대부분 역에서 입구가 높게 나타났고, $O_3$농도가 모든 역에서 아주 낮은 농도분포를 보였다.

낙동강하굿둑 하구 하류역의 기존 연구결과를 살펴보면, 대부분 하천에 의한 영향을 중심으로 수행되었다. 그러나, 현재의 낙동강하굿둑 하구 하류역은 기존 연구결과와는 달리 외해쪽의 외력 영향을 받는 양상을 보이고 있다. 따라서, 금회 연구에서는 이러한 현재의 양상을 위주로 수치모델링을 수행하여 주변 해역의 매립에 따른 유속저하에 따른 퇴적우세 현상을 설명하려 한다. 또한, 부산항 신항 건설로 인한 영향이 현재의 퇴적양상에 어떤 기여를 하고 있는지를 시간적으로 역추산하였다. 이러한 현상 재현을 위하여 5개분조를 고려한 해수유동 실험을 수행하고 이에 더하여 외해파랑 영향을 추가하여 실제 현상을 재현하였다. 연구결과, 낙동강하굿둑 하구 하류역 지형변화에 주된 영향을 주는 외력조건은 파랑 인 것으로 파악되었으며, 이에 상세한 결과를 도출하기 위하여 상세조건을 추가한 실험을 수행할 계획이다.

Presently, most of rail stations are situated on the surface of dowl1town and thus result in heavy traffic congestion and inefficient use of land. This paper analyzes the impact of alternative locations of station On urban traffic patterns by simulating transportation systems, of Busan city. Since location of station has long-term effects on land use and transportation, 20 years forecast of land use change, trip generation, trip distribution, modal split and network assignment was performed for each alternative, and aggregate Impacts On passenger-km and passenger-hour were computed. The result indicated that Bujeon is the most desirable location of station in terms of traffic movement, compared to the alternative locations of Sasang and existing station. Relocation of rail station, however, should be decided with broader analysis including other aspects, such as urban development, environment, construction and operating costs, etc.

2000년 9월에서 2003년 1월까지 부산 지하철 역사를 대상으로 CO, NO, $NO_2$ 그리고 $O_3$ 등 오염물질 4가지를 실내외 실외로 나누어 측정하고 그 결과를 계절별, 연도별로 분석하여 실내와 실외 대기질 특징에 대해 살펴보았다. 통행량의 많고 적음에 따른 오염도를 비교하기 위해 서면역과 두실역의 농도비를 계절별로 비교.분석해 본 결과 서면역의 오염도가 높게 나타났다. 서면역은 환승역이므로 역 내의 승강장 지점을 2곳으로 나누어 포집하고 계절별로 비교.분석해 보았다. 실내의 오염도를 파악하기 위해 오염물질별로 I/O비를 계절별(봄, 여름, 가을, 겨울), 연도별(2000년, 2001년, 2002년)로 분석하였다.

This study aims to explore practicable and sustainable strategies for locality documentation through networking, linking, and recontextualization of records in digital environments. It applies the 'spanDoc(SPAace-based Networked Documentation) Model to document Donghae-Nambu Railway areas placed in Busan Metropolitan City tentatively. Considering that mobility and openness are the main characteristics of Busan, railway areas and their stations can be proper places for representing such localities of the city. Moreover, there can be much experiences and memories of residents surrounding those areas, because Donghae-Nambu Railway has been used as short distance transportation facilities across the inner city of Busan since 1930's. This study tries to implement the documentation strategy for the selected space, following the procedures of the spanDoc Model. Firstly, this study develops the structure of the subjects through investigating the related information sources and archives from various collecting institutions. Secondly, it carries out records surveys to identify the essential records types for documenting the Donghae-Nambu Railway areas. Thirdly, it describes the subjects and sub-subjects, and the entries of places, people and subjects for adding to the dictionaries. Finally, it links many entities such as subjects, records, and dictionary, and builds the databases regarding the inter-links and systematic accumulation of the outputs of each step.

Noise levels of the three subway lines of Busan city have been investigated. Averaged cabin noise of the train has been measured during the train trip for each station. It has been measured with separation of day time (9:00~18:00) and night time (18:00~22:00) measurements but there was no big difference on the measured data. Repeating for the measured data has been confirmed with twice measurements in May and June 2010. Several noise effects to the subway noise levels of Busan are explained. Those are screen door effect, rail road surface condition, subway train type and curvature of railway. Among three subway lines of Busan city, the line 2 is relatively noisy and its reasons are studied. It has been shown that the screen door effect is 10 dB(A) and S shape of sharp curve contributes in high noise level.

The purpose of this study is to analyze how the commuting areas in the Busan metropolitan area have been changed during 2000~2010. For this purpose, I set the boundary of the Busan metropolitan area by using linkage indicators, and analyzed the changes of the commuting areas by using factor analysis. The commuting areas in the area were divided into four subregions, including East Busan, West Busan, Gimhae/Changwon, and Ulsan. The commuting area of West Busan has been shrinking, and the commuting network structure between Gangseo-gu/Buk-gu/Sasang-gu and their geographically adjacent Gimhae/Changwon has been gradually strengthened. This has resulted from the increase of reverse commuting from West Busan to Gimhae/Changwon. Ulsan has formed an independent commuting area in the area.

An estuary is a transitional water area that links the land and sea through rivers and streams, transporting various components from the land to the sea, which plays an important role in determining primary productivity in the coastal environment, and this coastal ecosystem captures a huge amount of carbon into biomass, known as blue carbon, which mitigates climate change as a potential carbon reservoir. This study examined the variation of mean grain size and organic carbon content of the surface sediments for 6 years and analyzed their relationship in the western and southern estuarine areas (Han River Estuary, Geum River Estuary, Yeongsan River Estuary, Seomjin River Estuary, and Nakdong River Estuary) and the East Sea upwelling area. During the sampling period (2015 to 2020), seasonal variation of both properties was not observed, because their variations might be controlled by diverse oceanographic environments and hydrographic conditions within each survey area. However, despite the synoptic problem of all samples, the positive relationship was obtained between the averages of mean grain size and organic carbon content, which clearly distinguishes each survey area. The unique positive relationship in all estuarine areas implies that the same process by sediment clay particles is important in the organic carbon accumulation. However, additional important factor may be expected in the organic carbon accumulation in the East Sea upwelling area. Further necessary data (sedimentation rate, dry bulk density etc) should be required for the estimation of carbon stock to evaluate the major estuaries in Korea as potential carbon reservoirs in the coastal environment.

The purpose of this study is to empirically analyze the impact of role stress (role conflict, role ambiguity, and role overload) on career commitment and turnover intention in small and medium-sized hospital workers in Busan. The subjects of the study were 418 nursing and administrative workers engaged in hospitals and general hospitals in Busan. Frequency analysis, correlation analysis, and regression analysis were conducted for empirical analysis. The results of the study are as follows. First, significant differences in some research variables were identified according to gender, age, educational background, marital status, and working years. Depending on the job type, there were significant differences in all variables such as role conflict, role ambiguity, role overload, career commitment, and turnover intention. Second, role stress was found to have a significant negative effect on career commitment and a significant positive effect on turnover intention. Among the role stress, it was confirmed that the role overload had the strongest influence on career commitment and turnover intention. This study is meaningful in that it analyzed the influence of role stress, including workers in all occupations, including nursing jobs, and empirically revealed the meaning of role stress as an explanatory variable of career commitment and turnover intention.
