  • Broadly speaking, in order to analyze the water quality improvement effects of the implementation of the Total Water Pollutant Management System in the Sapgy-Lake waterways, a reference was made to the [Plans for implementation of the Total Maximum Daily Load(TMDL)] in 3 cities (Cheonan, Asan, Dangjin). The results of the investigation into the plans to reduce the pollutant load show in that region show that there are plans to reduce pollution for a total of 16 reduction facilities. As for the result of the computation of the reduction in the load, these measurements were computed at the Gokgyo-stream basin and Namwon-stream basin, with BOD and T-P at the Gokgyo-stream basin reduced by 13.9 % and 13.3 %, respectively, while BOD and T-P at the Namwon-stream were reduced by 3.7 % and 3.3 %, respectively. In this way, thus using the results of the water quality forecast of Sapgyo-Lake in measures for the improvement of water quality (in accordance with the implementation of the TMDL), and using the QUAL-MEV model and EFDC model, it is noted that BOD will be improved by 26.4 % from 6.1 mg/L to 4.5 mg/L 0.0 %, T-P by 36.7 % from 0.168 mg/L to 0.107 mg/L and TOC by 26.4 % from 7.7 mg/L to 5.6 mg/L. However, it is forecasted that the targeted standards for the medium influence area will not be achieved. Evidently, Gokgyo-stream and Namwon-stream have been implementing the Total Water Pollutant Management System for the BOD items since January 1, 2019, but the Sapgyo-stream and Muhan-stream were excluded from being designated as subject regions. As such, it is noted now that it is necessary to implement the TMDL for the entire Sapgyo-Lake water systems including Sapgyo-stream and Muhan-stream in order to improve the water quality of Sapgyo-Lake, and likewise the T-P should be designated as the substance subjected to management in addition to BOD.

  • 수출산업으로 인하여 경제성장을 이루한 우리나라의 경우에는 외항운송업의 경제적 중요성이 매우 크다. 이는 정부가 주도적으로 외항운송 산업을 육성하였으며, 그 결과 세계 상위 10대 외항운송국가로 발전하게 되었다. 그러나 최근 들어 중·소 외항운송업의 부실경영과 국가 간 무역 분쟁으로 인해 외항운송업은 장기적인 침제기를 맞이하게 되었다. 따라서 이들 업체가 다시 회복하기 위해서는 무엇보다 운영상의 비효율성을 재정비하여 효율적인 생산 활동을 실시하여야 할 것이다. 이에 본 연구에서는 DEA 분석을 통해 비상장 국내 외항운송업 상위 10% 기업을 대상으로 경영효율성을 분석하며 비효율적인 기업의 투사값을 제시하며 벤치마킹의 대상이 될 수 있는 기업들의 참조집합을 확인하고자 한다. 이를 위해 총 10개 외항운송업을 대상으로 CCR와 BCC모형의 효율성과 규모수익성(RTS)을 분석하였다. 분석결과 BCC 효율성이 1인 기업은 총 6개 기업, CCR 효율성이 1인 기업은 총 5개 기업으로 나타났다. 그리고 BCC, CCR 효율성이 모두 1인 기업은 총 5개 기업이었다.

  • Objectives: The objective of this study is to understand the factors having effects on the view of marriage of female university students, and also to present the reference data for establishing the measures for having the positive view of marriage of female university students. Methods: An online survey was conducted targeting total 254 female university students of two universities in Gyeonggi region, from October 1 st to November 13th 2020. The results of this study are as follows. Results: First, to the question related to the intent to marry, total 70% of them responded that they had intent to marry. In the time of marriage, they said they would marry when getting financially stable. The 30% of subjects said that they would choose non-marriage because they wanted to continuously enjoy free life and they did not want to bear burden related to childbirth and child-rearing. Second, in the results of analyzing differences in the view of marriage according to the general characteristics, the students with intent to marry showed the higher romantic view of marriage, instrumental view of marriage, and exclusive view of marriage than the students without intent to marry, which showed significant differences. Third, the view of marriage were the factors having the greatest effects on the intent to marry of female university students. Conclusion: Based on such results of this study, it would be necessary to focus on the policies that could positively change the view of marriage of female university students. It would be needed to establish the social·institutional support measures for work-life balance by reducing women's burden of childbirth and child-rearing. To the question about the time of marriage, the most subjects responded that they would do so when the economic ability and stable job were equipped. Thus, there should be the systematic youth employment support system that could help the students to quickly and stably enter society and to become financially independent after graduation. Also, for the formation of positive family relation, it would be necessary to develop·operate the educational programs for forming positive family relation and desirable communication methods for each subject(spouse, parents, children, siblings, and etc.).

  • How to study Southeast Asia (SEA)? The need to explore and identify methodologies for studying SEA are inherent in its multifaceted subject matter. At a minimum, the region's rich cultural diversity inhibits both the articulation of decisive defining characteristics and the training of scholars who can write with confidence beyond their specialisms. Consequently, the challenges of understanding the region remain and a consensus regarding the most effective approaches to studying its history, identity and future seem quite unlikely. Furthermore, "Area Studies" more generally, has proved to be a less attractive frame of reference for burgeoning scholarly trends. This paper will propose a new tool to help address these challenges. Even though the science of artificial intelligence (AI) is in its infancy, it has already yielded new approaches to many commercial, scientific and humanistic questions. At this point, AI has been used to produce news, generate better smart phones, deliver more entertainment choices, analyze earthquakes and write fiction. The time has come to explore the possibility that AI can be put at the service of the study of SEA. The paper intends to lay out what would be required to develop SEABOT. This instrument might exist as a robot on the web which might be called upon to make the study of SEA both broader and more comprehensive. The discussion will explore the financial resources, ownership and timeline needed to make SEABOT go from an idea to a reality. SEABOT would draw upon artificial neural networks (ANNs) to mine the region's "Big Data", while synthesizing the information to form new and useful perspectives on SEA. Overcoming significant language issues, applying multidisciplinary methods and drawing upon new yields of information should produce new questions and ways to conceptualize SEA. SEABOT could lead to findings which might not otherwise be achieved. SEABOT's work might well produce outcomes which could open up solutions to immediate regional problems, provide ASEAN planners with new resources and make it possible to eventually define and capitalize on SEA's "soft power". That is, new findings should provide the basis for ASEAN diplomats and policy-makers to develop new modalities of cultural diplomacy and improved governance. Last, SEABOT might also open up avenues to tell the SEA story in new distinctive ways. SEABOT is seen as a heuristic device to explore the results which this instrument might yield. More important the discussion will also raise the possibility that an AI-driven perspective on SEA may prove to be even more problematic than it is beneficial.

  • Aging rate of rural area in our country is relatively high compared to that of the urban area. Thus, the introduction of meal service for the elderly residing in the rural area is necessary for their better living quality. Food habit, health and the nutritive intake conditions during the busy farming season were surveyed and comparative analysis of dietary intake for the introduction of meal service in pavilion of the elderly living in Chungnam, Kangwon, Jeonnam and Kyungbuk was performed for basic reference data of meal service introduction to the pavilion of the elderly in rural area. In general subject, the male elderly had a significant difference in marital state and showed that 79.4% was married and 20% was separated by death(P<0.05). In allowance, there were no significant difference but most of them lived with less then three hundred thousand won and especially, female lived with less then one hundred thousand won. In health state, the female elderly showed significant difference on difficulty with every day activity but with small trouble although they had to prepare their own meal(P<0.05). The condition dental health conditions of the female elderly had a significant difference showing bad conditions in following order; Kangwon(48%)>Chungnam(38.1%)>Kyungbuk(22.9%)>Jeonnam(22.5%)(p<0.05). The female elderly showed a significant difference in usage of denture and number of the female elderly without using the denture were very high(p<0.05). In nutrition intake condition, amount of sodium was very high but intakes of fiber and calcium were relatively 1ow(P<0.05). Meal service introduction in the pavilion of the elderly is suggested for the improvement of the life quality of the elderly in rural area. When developing the menu for them, conditions such as shortage of the fiber and calcium in diets, the dental conditions should be considered.

  • During recent decades, the number of mixed attribute products (henceforth mixed products), which have both utilitarian and hedonic benefits, has increased dramatically. Despite these products' growing popularity, academic research has paid little attention to them, and there remains a gap between theory and the real world. Hence, our study was undertaken to understand consumers' perceptions about and behaviors toward mixed products, as well as factors affecting the evaluation and choice of these products. We divided mixed attribute products into two categories: mixed utilitarian products (utilitarian products adding hedonic attributes) and mixed hedonic products (hedonic products adding utilitarian attributes). We then showed how adding different attributes affects consumers' perception, willingness to pay (WTP), and the choice of mixed attribute products compared to pure utilitarian or pure hedonic products. We conducted an experiment using a within-subject design. A total of 160 office workers and college students participated in the study. The pure utilitarian product used in the study was orange juice, and the mixed utilitarian product was carbonated orange juice. The pure hedonic product was chocolate, and the mixed hedonic product was polyphenol enriched chocolate. Results showed that consumers perceived a mixed utilitarian product to be less utilitarian, less pleasurable and more guilty than a pure utilitarian product. On the other hand, a mixed hedonic product was perceived to be more utilitarian, less pleasurable and less guilty than a pure hedonic product. Also, WTP for a mixed hedonic product was higher than WTP for a pure hedonic product, but WTP was lower for a mixed utilitarian product than for a pure utilitarian product. Furthermore, mixed hedonic products were likely to be evaluated more favorably when they were presented together with pure hedonic products, more so than when they were presented alone. Finally, when compared to low self-control participants, high self-control participants chose mixed hedonic products more frequently. The present study contributes to the existing literature on utilitarian and hedonic consumption by adding to the sparse literature on the consumption of products that have both utilitarian and hedonic purposes. Also, our research findings provide several useful implications for practitioners in related fields. First, the current study provides marketers with a useful guide for understanding consumers' perceptions of these types of products, and helps to predict how adding different attributes influences these products. Second, this study has examined the conditions that may moderate the evaluation and choice of hedonic base products and this finding will serve as a good reference for marketers of mixed hedonic products in marketing communication strategy, in-store marketing and targeting. Specifically, comparative advertising with a pure hedonic product will be beneficial for a mixed hedonic product. Also, displaying mixed hedonic products near pure hedonic products may enhance the effectiveness of in-store marketing of mixed hedonic products.
