This study aims to investigate hydrogeological properties of the central area from Yangjeong-Dong to Sujeong-Dong in Busan Metropolitan City. For this study, pumping tests were carried out in the bedrock aquifer of Yangjeong-Dong and the unconsolidated aquifer near Busanjin railway station. The pumping test in the bedrock aquifer containing the Dongrae fault revealed specific hydraulic characteristics with respect to the fault. The pumping test in the unconsolidated aquifer revealed the hydrogeologic properties of both coastal landfill and fine sediments. It was found that the Moench's sphere-shaped dual-porosity model fits the bedrock aquifer, whereas the Neuman's uncofined aquifer model accords with the unconsolidated aquifer. The average transmissivity and storage coefficient of the bedrock aquifer are $2.75{\times}10^{-5}m^2/s\;and\;6.41{\times}10^{-5}$ and those of the unconsolidated aquifer are $8.24{\times}10^{-4}m^2/s\;and\;3.70{\times}10^{-3}$, respectively. On the other hand, slug tests gave average transmissivity and storage coefficient values of $9.84{\times}10^{-4}m^2/s\;and\;1.21{\times}10^{-2}$, respectively.

The purpose of this study is to clarify the mechanism and essence of problems by understanding the whole structure of the complicated problems that exist in the social welfare field with DEMATEL method, one of structural models. This paper consists of (1) What kind of social welfare problems exist in the community that is related to welfare? (2) What kind of thoughts do people who work in social welfare field have related to these problems? (3) Are there any differences in structure of thoughts among social welfare civil servants who take charge of planning and dividing budgets for community welfare, social workers who provide services personally and civic activists who criticize and keep watch on behalf of civilians? In order to achieve the purpose of this study, data were collected in Busan Busanjingu and the survey was conducted from the year of 2005 when community welfare plan was first established up to now. The major structural problems of the community welfare of the Pusan Jin-gu, Korea, are: 1) welfare budget allocation procedure is not logical, 2) the outskirts of the Pusan Jin-gu are isolated as poor areas, 3) geographic imbalance is severe among communities, and 4) the social welfare response system to support future population structure needs to be more developed. All of these problems are the fundamental origin to the social resource disparity within communities. The major problems of the community social welfare in Pusan Jin-gu, Korea were recognized by different perspective in terms of professional career such as social welfare civil servants, social workers, and civic activists. Majority of the social welfare civil servants thought "severe geographic imbalance"; majority of the social workers believed "lack of the social welfare response system to support the structure of the population in the future" and "disparity in social resources within the communities"; and majority of the civic activists said "limitation for understanding various social welfare needs because of short term need assessments" as main issues of the community social welfare. It seems that this paper is able to be used as a framework to establish community welfare plans and individual programs in Busan Busanjingu.

TBM 터널굴진시 공법적합성을 평가하기 위한 현장조사 및 물리탐사와 세부지질조사를 수행하였다. 해당지역은 부산시 진구 가야동과 동구 수정동이며 인근 수원지인 덕정정수장에서 생산하는 수돗물을 수정산 배수지까지 확대 공급함으로서 송수공급 계통의 이원화로 안정적인 수돗물공급을 수행하기 위한 배수지터널이다. 이론적으로 굴착속도는 암반의 반발경도, 일축압축강도, 석영함량 및 각종 지질특성에 의하여 좌우되는데, 실지 시공에 있어서는 현장여건상 지질조건이나 일축압축강도등 한정된 자료들을 토대로 시공에 임할 수밖에 없다. 이러한 한계를 극복하기 위한 모형개발을 목표로 본 연구에서는 다양한 현장시험을 토대로 한 TBM 굴진 적합성을 검토하고자 하였다. 국내 시공경험상 및 지질특성만을 고려 할 때 본 과업구간의 TBM 적용성은 양호할 것으로 판단하였으나, 뚜렷한 근거에 의거하지 않은 설계는 시공단계에서 엄청난 손실을 야기하게 되므로 보다 상세한 검토를 수행하게 되었다. 본 연구에서는 TBM 공법선정의 적합성을 검토하기 각종 조사 자료들을 정리하였고, 국내시험의 한계점들을 극복하기 위한 적합한 모형개발의 필요성을 제시하고자 하였다.

Purpose: In this study, the cavity data found through ground cavity exploration was combined with underground facilities to derive a correlation, and the ground subsidence prediction map was verified based on the AI algorithm. Method: The study was conducted in three stages. The stage of data investigation and big data collection related to risk assessment. Data pre-processing steps for AI analysis. And it is the step of verifying the ground subsidence risk prediction map using the AI algorithm. Result: By analyzing the ground subsidence risk prediction map prepared, it was possible to confirm the distribution of risk grades in three stages of emergency, priority, and general for Busanjin-gu and Saha-gu. In addition, by arranging the predicted ground subsidence risk ratings for each section of the road route, it was confirmed that 3 out of 61 sections in Busanjin-gu and 7 out of 68 sections in Sahagu included roads with emergency ratings. Conclusion: Based on the verified ground subsidence risk prediction map, it is possible to provide citizens with a safe road environment by setting the exploration section according to the risk level and conducting investigation.

This study intended to evaluate hydrogeological characteristics in relation to subsurface geology data obtained from borehole, groundwater level, borehole flowmeter test, and field hydraulic tests. The regression equation of groundwater level (Y) versus ground elevation (X) is expressed by Y=0.75X-7.00 with quite high correlation coefficient of 0.78. Relationship between groundwater level and thickness of landfill, alluvium, and weathered zone results in higher correlation of groundwater level (Y) versus natural log value of weathered tone (A) than other correlations, with the regression equation Y= exp(9.974A)-14.155. The result of groundwater flow measurement in the boreholes indicates that groundwater flows towards between south and southwest, and this approximately agree with regional distribution of groundwater levels.

Korean government annually estimates and reports the traffic safety index to evaluate the traffic safety of 228 Gu Gun. However, since the traffic safety index is derived from the spatially macroscopic perspective based on collected relative data, there are a couple of problems such as inability to investigate the individual traffic accidents on the spot, insecurity of accuracy and reliability of traffic safety index estimation method, and absence of establishing temporal relationship of traffic accidents. Thus, this study investigated temporal traffic safety in macroscopic manner for Gu Gun in Busan depending on the installation of the traffic safety facility (i.e., urban median), employing meta analysis. As a result, all Gu Gun in Busan except Saha, Buk, Dong, and Busanjin experienced more traffic accidents after installing the urban median, indicating that there are more rooms for improvement of macroscopic traffic safety evaluation.

The purpose of this study is to propose a ventilation corridor management plan to improve the thermal environment for Busan Metropolitan City. To this end, the characteristics of hot and cool spots in Busan were identified by conducting spatial statistical analysis, and thermal image data from Landsat-7 satellites and major ventilation corridors were analyzed through WRF meteorological simulation. The results showed the areas requiring thermal environment improvement among hot spot areas were Busanjin-gu, Dongnae-gu, industrial areas in Yeonje-gu and Sasang-gu, and Busan Port piers in large-scale facilities. The main ventilation corridor was identified as Geumjeongsan Mountain-Baekyangsan Mountain-Gudeoksan Mountain Valley. Based on the results, the ventilation corridor management strategy is suggested as follows. Industrial facilities and the Busan Port area are factors that increase the air temperature and worsen the thermal environment of the surrounding area. Therefore, urban and architectural plans are required to reduce the facility's temperature and consider the ventilation corridor. Areas requiring ventilation corridor management were Mandeok-dong and Sajik-dong, and they should be managed to prevent further damage to the forests. Since large-scale, high-rise apartment complexes in areas adjacent to forests interfere with the flow of cold and fresh air generated by forests, the construction of high-rise apartment complexes near Geumjeongsan Mountain with the new redevelopment of Type 3 general residential area should be avoided. It is expected that the results of this study can be used as basic data for urban planning and environmental planning in response to climate change in Busan Metropolitan City.

Purpose: This study was conducted to identify factors of COVID-19 stress, impulsiveness, and family strength on suicidal ideation of public nursing officials in community health centers. Methods: This study was a descriptive analysis study the subjects of this study were a total of 145 public nursing officials from community health centers in Busan. The data were analyzed using IBM SPSS/WIN 23.0 version. Result: The result of the predictor analysis showed that the motor impulsiveness (β=.383, p<.001), workload (β=.222, p=.003), cognitive impulsiveness (β=-.205, p=.012), bond (β=-.169, p=.033). The regression model showed an explanatory power of 24.1%. Conciusion: it is necessary to increase impulse and stress control ability, and to adjust the workload. In addition, it is necessary to systematically guarantee a working environment where practical vacation can be used, but it may not be a realistic alternative in a disaster crisis such as COVID-19, so indirect alternatives such as reinforcing infectious disease experts, improving the work environment, and psychological support to prevent suicide in advance are required.
