  • Excessive public loan with low interest and other tax benefits have been provided for fishermen, but much of them turned out to be little performed. There were the moral hazards of Suhyup in the process of executing the public loans. As the government gave the reimbursement on the financial loss of Suhyup resulting from the public loans, Suhyup had no responsibility of the bad debt loss. Therefore, Suhyup gave little efforts to reduce the non-performing. The government perceived this problem and tried to reduce the under-performing loans. Thus, the government decided to take limited responsibilities. Suhyup made the progress to reduce the under-performing public loans. Suhyup dealt with these situation and made the credit evaluation model of the fisherman's public loan. This paper is for the credit evaluation model in the fisherman's public loan, which explains the model development methodology and the model characteristics in detail. This evaluation model is composed of two sub-component model. the one is the quantitative model and the other is the qualitative model. The quantitative sub-model is for the identification of fishermen financial status and is based on the financial transaction information. Its development methodology is the CSS modeling for the consumer market. The qualitative sub-model is for the evaluation the business prospect and is based on the business information such as fisherman's management skills, technology, equipment. Its development methodology is the AHP. It provides the detailed information in the model development methodology, which is the ideal example such as the public loan. In addition it gives the information to the interest parties such as policy makers, suhyup and fishermen.

  • Consequence-Based Engineering (CBE) is a new paradigm proposed by the Mid-America Earthquake Center (MAE) to guide evaluation and rehabilitation of building structures and networks in areas of low probability - high consequence earthquakes such as the central region of the U.S. The principal objective of CBE is to minimize consequences by prescribing appropriate intervention procedures for a broad range of structures and systems, in consultation with key decision makers. One possible intervention option for rehabilitating unreinforced masonry (URM) buildings, widely used for essential facilities in Mid-America, is passive energy dissipation (PED). After the CBE process is described, its application in the rehabilitation of vulnerable URM building construction in Mid-America is illustrated through the use of PED devices attached to flexible timber floor diaphragms. It is shown that PED's can be applied to URM buildings in situations where floor diaphragm flexibility can be controlled to reduce both out-of-plane and in-plane wall responses and damage. Reductions as high as 48% in roof displacement and acceleration can be achieved as demonstrated in studies reported below.

  • Watershed models have been increasingly used to support an integrated management of land and water, non-point source pollutants, and implement total daily maximum load policy. However, these models demand a great amount of input data, process parameters, a proper calibration, and sometimes result in significant uncertainty in the simulation results. For this reason, uncertainty analysis is necessary to minimize the risk in the use of the models for an important decision making. The objectives of this study were to evaluate three different uncertainty analysis algorithms (SUFI-2: Sequential Uncertainty Fitting-Ver.2, GLUE: Generalized Likelihood Uncertainty Estimation, ParaSol: Parameter Solution) that used to analyze the sensitivity of the SWAT(Soil and Water Assessment Tool) parameters and auto-calibration in a watershed, evaluate the uncertainties on the simulations of runoff and sediment load, and suggest alternatives to reduce the uncertainty. The results confirmed that the parameters which are most sensitive to runoff and sediment simulations were consistent in three algorithms although the order of importance is slightly different. In addition, there was no significant difference in the performance of auto-calibration results for runoff simulations. On the other hand, sediment calibration results showed less modeling efficiency compared to runoff simulations, which is probably due to the lack of measurement data. It is obvious that the parameter uncertainty in the sediment simulation is much grater than that in the runoff simulation. To decrease the uncertainty of SWAT simulations, it is recommended to estimate feasible ranges of model parameters, and obtain sufficient and reliable measurement data for the study site.

  • The current Total Pollution Load Control (TPLC) sets the Target Water Quality (TWQ) by utilizing the delivery ratio, unit loads, and water quality modeling, it also allocates the watershed's permitted discharge load. Currently, common target pollutants of every unit watershed in TPLC are BOD and T-P. This study has reviewed the 1th and 2th of TWQ setting process for the Nakdong River 3th TWQ setting in Total Pollution Load Control (TPLC). As a result of review, 1th and 2th were divided into one management basin (mulgeum) for setting management goals. However, 3th was divided into six management basins (mulgeum, gnagjeong, geumho river, nam river, miryang river, end of nakdong river). The principle of management goal setting were to achieve the objective criteria of Medium Areas for the linkage of the water environment management policy. And Anti-Degredation (principle of preventing deterioration) were applied to the 3th TWQ. Also, additional indicators were considered in accordance with the reduction scenarios for the final management goals.

  • There is a more urgent call for educational methods of machine learning in medical education, and therefore, new approaches of teaching and researching machine learning in medicine are needed. This paper presents a case using machine learning through text analysis. Topic modeling of news articles with the keyword 'asbestos' were examined. Two hypotheses were tested using this method, and the process of machine learning of texts is illustrated through this example. Using an automated text analysis method, all the news articles published from January 1, 1990 to November 15, 2016 in South Korea which included 'asbestos' in the title and the body were collected by web scraping. Differences in topics were analyzed by structured topic modelling (STM) and compared by press companies and periods. More articles were found in liberal media outlets. Differences were found in the number and types of topics in the articles according to the partisanship and period. STM showed that the conservative press views asbestos as a personal problem, while the progressive press views asbestos as a social problem. A divergence in the perspective for emphasizing the issues of asbestos between the conservative press and progressive press was also found. Social perspective influences the main topics of news stories. Thus, the patients' uneasiness and pain are not presented by both sources of media. In addition, topics differ between news media sources based on partisanship, and therefore cause divergence in readers' framing. The method of text analysis and its strengths and weaknesses are explained, and an application for the teaching and researching of machine learning in medical education using the methodology of text analysis is considered. An educational method of machine learning in medical education is urgent for future generations.

  • According to the notion that anxious attachment may not explain depression fully, there has been abundant studies investigating the mediating factors affecting the relationship between anxious attachment and depression. However, there was no previous study examining the mediating effect of self-absorption. Therefore, the present study examined the mediating effect of self-absorption on the relationships between adult anxious attachment and depression for 283 college students. To examine relationships among variables, structural equation modeling analysis was utilized. and the present study found a partial mediation effect of self-absorption in the relationship between anxious attachment and depression. This result suggests that anxious attachment influences attentional process and as a result, the maladoptive self-focused attention can precipitate depression. Current findings can contribute to the field by providing knowledge about risk factors and cognitive mediators affecting mental health of college students who are in "transitional period" in their life. Future studies can investigate interactions among risk, protective, and mediating factors affecting the relationship between anxious attachment and depression among college students.

  • This study examined the effects of negative parenting attitudes on adolescents' academic helplessness through the mediating effects of social withdrawal and smartphone dependency. Data from the panel study of Korean Children and Youth Panel Survey 2018 (KCYPS 2018) collected by the National Youth Policy Institute (NYPI) was used to examine the research model. The subjects of the study consisted of 2,541 first grade middle school students (1,375 boys and 1,166 girls). Confirmatory factor analysis [CFA], structural equation modeling [SEM], and bootstrapping analysis were conducted by means of SPSS 25.0, AMOS 25.0, and Hayes's PROCESS programs to examine the serial multiple mediating effects. The study results were as follows. First, negative parenting attitude had a direct effect on adolescents' academic helplessness. This implies that adolescents who perceive their parents' attitudes to be high in coercive, rejective, and chaotic levels indicate that they can easily get exhausted in academic settings. Second, negative parenting attitudes had an indirect effect on adolescents' academic helplessness through social withdrawal and smartphone dependency. The results suggest that a high level of negative parenting attitude leads to higher social withdrawal and smartphone dependency that influences adolescents' academic helplessness.

  • This case study aims to describe the principles and methods of records management applied to the systematic management of records in the KDI School of Public Policy and Management, and the process of its practical implementation. It provides more extensive coverage than most existing studies on records management, dealing with all procedures from the theoretical modeling to the records management system building. The School has built the Records Center that can integratively manage its administrative records and archives that have been erratic and unsystematic over the years. As a result, the introduction of records management has become a basis for succeeding the achievements of the KDI School and its history as well as supporting administrative and knowledge resources. As well, it is intended to be a guide for other schools or institutions when building the records management system.
