  • Recently, there are increasing attempts to utilize deep learning methodology in the fashion industry. Accordingly, research dealing with various fashion-related problems have been proposed, and superior performances have been achieved. However, the studies for fashion style classification have not reflected the characteristics of the fashion style that one outfit can include multiple styles simultaneously. Therefore, we aim to solve the multi-label classification problem by utilizing the dependencies between the styles. A multi-label recognition model based on a graph convolution network is applied to detect and explore fashion styles' dependencies. Furthermore, we accelerate model training and improve the model's performance through transfer learning. The proposed model was verified by a dataset collected from social network services and outperformed baselines.

  • Eutrophication and algal blooms can lead to increase of taste and odor compounds and health problems by cyanobacterial toxins. To cope with these eco-social issues, Ministry of Environment in Korea has been reinforcing the effluent standards of wastewater treatment facilities. As a result, various advanced phosphorus removal processes have been adopted in each wastewater treatment plant nation-widely. However, a lot of existing advanced wastewater treatment processes have been facing the problems of expensive cost in operation and excessive sludge production caused by high dosage of coagulant. In this study, the sedimentation and dissolved air flotation (SeDAF) process integrated with sedimentation and flotation has been developed for enhanced phosphorus removal in wastewater treatment facilities. Design and operating parameters of the SeDAF process with the capacity of 100 ㎥/d were determined, and a demonstration plant has been installed and operated at I wastewater treatment facility (located in Gyeonggi-do) for the verification of field applicability. Several empirical evaluations for the SeDAF process were performed at demonstration-plant scale, and the results showed clearly that T-P and turbidity values of treated water were to satisfy the highest effluent standards below 0.2 mg/L and 2.0 NTU stably for all of operation cases.

  • England's green belt policy as it delivered its framework to designating the development restriction zones(DRZ) in Korea is the key to address issues which try to change green belt boundary or/and housing development. Therefore it should necessarily be reviewed on the understanding of how England has been formulating a national policy to deal with the issues focusing on opportunities for housing development and recreation. This study explored the discourse and framework of England's green belt policy as well as driver changes of housing development and recreation. Results show several characteristics of England's green belt policy which are civil society consensus on conservation and management, limited small-scale housing development through management of release rates, a systematic procedure for application and approval, open-recreation space expansion and utilisation under the premise of conservation of natural green areas, and management structure by the involvement of NGO organisations. Therefore, five suggestions can be delivered to developing Korea's DRZ frameworks: first, preceding social consensus on the preservation value of development-restricted zones, second, addressing housing shortages in different alternatives e.g.) environmental-friendly small-scale housing, third, institutionalising the total proportion of release, fourth, establishing an open-recreation space, fifth, introducing expanded public-private partnerships. Ultimately securing the legitimacy of the nation's development-restricted zone system can contribute positively to the environment preservation and human health by promoting public leisure activities in terms of the recent increase in external activities caused by the Covid-19 crisis. Concluding remarks are here that the understanding of England's green belt policy can be delivered to and help formulate domestic policy addressing current issues.

  • In the era of untact, the "Chabak" using cars as accommodation spaces is attracting attention as a new form of travel. Due to the advantages, including low costs, convenience, and safety, as well as the characteristics of the vehicle enabling independent travel, the demand for Chabak is continuously increasing. Despite the rapid growth of the market and related industries, little academic has investigated this trend. To establish itself as a new type of travel culture and to sustain the growth of related industries, it is essential to understand the public perception of Chabak. Therefore, based on the marketing mix theory and big data analysis, this study analyzes the public perception of Chabak. The results showed that Chabak has established itself as a consumer-led travel culture, contributing to the aftermarket growth of the automobile industry. Additionally, consumers were found to be increasingly inclined to enjoy travel economically and wisely, and actively share information through social media. This initial study on the new travel trend of Chabak is significant in that it employs big data analysis on a theoretical basis.

  • In this study, death preparation was used as an independent variable, with ego integrity as successful aging used as a dependent variable while depression and death anxiety were used as mediate variables. The purpose of this study is to investigate the differences of the study variables according to the demographic characteristics of the research subjects, and to create a database for developing and improving current educational programs and welfare services to help the elderly achieve successful aging. Two hundred and eighty three elderly people above the age of sixty in Cheongju city were given standardized questionnaires, and the collected data were analyzed. The results of this study are the following. First, the differences of the study variables according to the level of education, health, economy, and social involvement of the elderly are statistically significant. Second, there exists a positive relationship between mental preparation for death and ego integrity (successful aging) while there is no such relation in case of formal preparation for death and ego integrity. Third, depression and death anxiety of the elderly partially mediate ego integrity, which leads to successful aging.

  • Objectives: The purpose of this study is to critically review the recent discourse on single-person households (SPH) that appeared in Korean newspapers. Specifically, we analyzed articles in five major daily newspapers, which are representative of the media in Korean society, and examined the types of titles, subjects, and contents of articles in which SPH were mentioned. Method: For this purpose, 538 articles on SPH or "living alone" that appeared in the five major Korean newspapers during 2011-2017 were analyzed using content analysis methods. Results: Our analysis revealed eight major topics(living arrangement and household characteristics; financial instruments; food, clothing, and housing culture; policy; welfare; relationships; safety; values and attitudes). The results show that there is a surge of articles portraying neutral images of SPH in Korean newspapers, thereby emphasizing the recent growth in the number of SPH and the information relating to this population group. Although negative images of SPH continue to exist in the discourse, in recent times we found these attitudes to have become less prevalent compared to neutral images or even positive discourse. We also found that the discourse on these topics and arguments can be divided into four themes-the diversity of SPHs, the solo economy for single households, safety issues, and social relationships. Conclusions: Theoretical and policy implications on family studies relating to SPH are discussed.

  • Ahn Jaihong tries to establish a unified nation state with Dasarism through which conflicts of right and left could be sublated. Dasarism has two features; one is nationalism and the other is centrism. His nationalism recognizes national identity and national sovereignty as two faces of one coin and sublates nationalism and globalism. His centrism is thought to be a route to true democracy which can sublate liberalism and communism and a route to nation's sovereignty. However, his dasarism did not make any impact on political reality of that day. Its today's value must reside in its proposals to harmonize nation and world, and to protect the social weak, and to pursue a central route of reunification.
