  • This paper focuses on the improvement of the influence coefficient matrix method for estimation of local ice load on the icebreaking research vessel ARAON. The influence coefficient matrix relates ice pressure on the hull plate to the measured/calculated hull strain/stress. Conventionally von Mises equivalent stresses representing hull stresses and ice pressure acting on the hull plate are utilized to assemble the influence coefficient matrix. Because of the three dimensional features of the ship-ice collision process, an enhanced method to assemble the influence coefficient matrix is derived considering ice loads in the X, Y, and Z direction simultaneously. Furthermore the location of ice loads acting on hull-plate may fall outside the measuring sensor area, and the enhanced influence coefficient matrix is modified to reduce the difference between the actual and the estimated ice loads by expanding the domain outward from the sensor area. The developed method for enhanced influence coefficient matrix is applied to IBRV ARAON during the 2019 Antarctic ice field test and the local ice loads in three directions are efficiently calculated compared to those by a conventional method.

  • The purpose of this study is to shed light on the characteristics of the social relations of migrant workers in the Ansan area and the factors for the construction of those characteristics. The social relations of migrant workers in the Ansan area are affected by the Korean government's policy of EPS, a short-term rotation policy and its ban on the settlement of migrant workers. These workers are likely to form a temporary and bounded social relationship. The bounded social relationship of migrant workers to society is one of the major factors that put them in social poverty. Ethnic communities, support organizations for migrant workers, and local government agencies have assumed the task of helping build the network among migrant workers of various ethnic backgrounds as well as aiding their participation in local social activities. The status of a temporary resident is the prime reason for spatial exclusion and social poverty among migrant workers. To prevent the exacerbation of these phenomena, this study suggests that the government reconsider its short-term work permit policy for less skilled workers.

We applied to the rapid assessment of ES method to Ansan city and local registers selected Ecosystem assets that considered to space of ES. Ecosystem assets were measured 5 types Likert scale about 37 indicators of ES and confirm the main ES through the basic statistics. Furthermore Ecosystem assets classified according to similar character of ES. Ecosystem assets of Ansan were selected 47 site and Local climate regulation, Research and education, Primary production was high among the ES indicators. As a result two main group deduced that ecological education group(such as Research and education, Habitat) and safety regulation group(such as Air regulation, Fire regulation) through the factor analysis. In terms of location characteristics of each group, the ecological education-centered ecosystem assets were located near the downtown area, while the safety regulation group was located at the outskirts, such as mountains and coasts. This indicates that the ecological education about the habitat provision can be achieved in Ansan city downtown area and that outskirts should be approached from the aspect of ecological function to establish a plan. The result of Rapid assessment of ES, which can be lead a balanced and developmental consultation when establishing polices for environment planning and management in region.

  • According to data released by the Covid 19 Self-Employed Emergency Response Committee, 95.6% of small business sales due to Covid 19 have decreased over the past two years, and the damage has further increased due to social distancing for quarantine. However, as all social distancing guidelines have rebeen lifted, and the commercial district has been revitalized, the Seoul Metropolitan Government is pushing for a project to foster local brand commercial districts so that small business owners or prospective founders who have closed their businesses due to the prolonged COVID-19. Therefore, this study propose the model that recommends alley commercial districts suitable for founders among the five alley commercial districts selected for the project to foster local brand commercial districts in Seoul. The Seoul Metropolitan Government's local brand alley commercial recommendation system recommends major population age groups and major industries in the commercial district by combining the population perspective model using Xgboost and the commercial district characteristic model using Decision Tree.

  • Survey on the food intake status and health condition of the elerly over 65 years old living in Damyang Jeonnam was performed and meal menus for the pavillion were developed using local products. Allowance of the elderly less than 100,000 won was 45%. The local products of the area recognized by the elderly were bamboo shoot (30%) > bamboo (22.5%) > bamboo basket (12.5%) > do not know (15%) > green tea (10%) > rice(7.5%) > vegetable. In dental health, 52.5% of them had bad condition but 62.5% did not use denture at all. The most favorate foods were Korean (92.5%) and Chinese and Japanese were favored by 5%, and 2.5%, respectively. In percentage of eat-out and use of instant foods, 42.5% of them answered that eating-out chances were very rare and 62.5% answered that they do not use instant foods at all. Potassium intakes for the male and female elderly were significantly very low with values of 2579.2 mg and 2601 mg, respectively (p < 0.05). Calorie intakes for men were 1678.5 kcal, which was only 84% of RI and 1470.8 kcal for women (92%). Shortages of nutrition including calcium intake and others were very serious and the meal was not nutritionally balanced based upon the study of GMDFO. The menu for the elderly in busy farming season of the area were developed with the use of local products and the information from the study.

  • Background: Hapcheon-gun, Gyeongsangnam-do, is designated as an emergency medical vulnerable area, facing significant challenges in transporting and treating emergency patients. A detailed analysis of the regional emergency medical system is required to identify effective solutions. Methods: This study employed a mixed-methods approach, combining quantitative data from the National Emergency Medical Information System and emergency activity logs with qualitative data from focus group interviews involving 24 stakeholders, including medical staff, paramedics, civil servants, and local residents. Results: Quantitative findings indicated an aging population in Hapcheon-gun, with a growing number of elderly emergency room users. Despite the utilization of local emergency medical institutions, a lack of trust and preference for urban hospitals led even patients with mild conditions to seek care at higher-level facilities. Following the COVID-19 pandemic, transport distances and times for patients using 119 emergency services increased. Qualitative analysis identified several issues: limited capacity of local institutions, challenges in patient transport due to misaligned emergency medical zones, an increase in severely ill patients, and the absence of a coordinated emergency medical consultative body. Recommendations include strengthening local institutions through government support, realignment of emergency zones, legal reforms, the establishment of a continuous consultative body, and enhancing the capacity of medical staff, paramedics, and residents. Conclusion: Improving the emergency medical system in Hapcheon-gun will require targeted efforts in institutional strengthening, legal and administrative support, and capacity-building initiatives.

  • This study was to investigate the impact of region-wide travel pattern on local fiscal capacity in the Seoul metropolitan area. The study adopted both factor analysis and regression modeling for it, while using fiscal-and travel-related variables as well as urban characteristics determining travel patterns. We used the former method to compress independent variables of travel and urban characteristics because of strong correlationship between them. Four factors identified by the analysis output were adopted in regression models with some dependent variables representing local fiscal capacity. Their results resulting from both analyses showed that local fiscal inequality within the metropolitan area is driven by region-wide travel Patterns such as total trips. inner trip ratio, and the ratio of trips from and to the Seoul city.

  • Central government of Korea devised the balanced national development as one of important agenda of government administration, and set up special act for balanced national development. According to special act, a plan to transfer public institutions to local areas was publicized on June 24, 2005. Thus 175 public institutions located in the capital area will be transfered to 11 local governments, and innovative cities will be built in local areas until 2012. However, Gwangju and Jeonnam province adopted not two individual innovative cities but one common innovative city in cooperation with two local governments. This study focuses on the characteristics of location selection process of common innovative city in Gwangju and Jeonnam province. Discussion about construction of common innovative city was started in need of new model for common development of two provinces, and most of peoples agreed a plan to establish on common innovative city within Jeonnam area near Gwangju area. Gwangju Jeonnam Regional Innovation Council, in particular, played an important role in the process of location selection and initial discussion about common innovative city. In addition, Common innovative city to be built in Naju city will be provided positive regional development effects in several dimensions. In result, it has been evaluated as a successful model of innovative city to be constructed with transfer of public institutions to local areas.

  • Purpose: Numerous techniques have been introduced to reconstruct the perineal area in order to preserve function of both the recipient and the donor site while satisfying aesthetic results. There are several advantages of using the pudendal aretery perforator based flap in that it provides thin coverage of defect area and a relatively excellent circulation through perforators. The perineal region can be divided into two areas : the urogenital triangle and the anal triangle. Since each area differs in structure and function so does its reconstructive plan. The authors of this article report clinical results obtained from pudendal artery perforator based reconstructed cases according to each differrent triangles. Methods: A total of 15 patients who underwent perineal reconstruction were enrolled in our study between the year 2002 and 2006. There were 4 cases of vaginal cancer, 4 cases of extramammary Paget's disease, 1 case of rectovaginal fistula in females and 2 cases of Paget's disease and 4 cases of Fournier's gangrene in male cases. The follow up period was on average 6 month. In female, superfical pudendal artery perforator based local flap were used to reconstruct the urogenital triangle defects, while internal pudendal artery perfoator based local flaps were used to reconstruct the anal traingle defects. In males the gracilis myocutaneous flap and internal pudendal artery perforator based local flaps were used in reconstruction of the scrotum and perineal defect. Result: In females, there was 1 case of partial flap necorsis that employed the superficial pudendal artery perforator but secondary repair through the internal pudendal artery perforator based local flap was done. In addition, there were 4 wound dehiscence cases in females and 2 cases in males. Conclusion: We believe that a better aesthetic and functional outcome can be achieved in perineal reconstruction if discrete surgical planning is carried out systematically categorizing the choice of flap employed acccording to distinct anatomical regions : the urogenital and the anal triangle.

  • Recently, industrial locations have faced changing trends under the influence of emerging industries as well as advanced new technologies. So the purpose of this study is to analyze the spatial distribution and locational factors of biotechnology industry formed around the Seoul Metropolitan area and Daejeon city, both of which are centers of Korean biotechnology industry, and is also to identifytheir locational characteristics. Major results of this study can be outlined as follows: First, from the mid 1990' s to 2000, Korean biotechnology industry has rapidly developed owing to central and local governmental support policies and systems as well as changes in domestic economic environment due to Korean financial crisis. Secondly, it was found that spatial distribution of Korean biotechnology industry converged on the Seoul Metropolitan area till 1990, but shifted from there to Daejeon and Chungcheong area from 1990 to 2000. Particularly after 2000, positive local governmental efforts to attract biotechnology players have driven the spatial distribution of biotechnology industry to shift from Seoul Metropolitan area and Daejeon or adjacent area gradually to other profitable locations. In terms of locational factors, it was found that the locations of Korean biotechnology industry converged primarily on university or college campus and biotechnology venture center, particularly on locations adjacent to superhighway or expressway. Locational factors varied depending on region, industrial type and business growth phase. Therefore, it is advisable that our central and local government should make and implement practical and useful policies in favor of biotechnology business depending on region, industrial type, business growth phase, rather than depending on uniform locational policies.
