  • This study was an exploratory study for the development of a competency-based social welfare curriculum. This study was conducted through a literature review focused on guidelines for social welfare published by the KCSWE (Korean Council for Social Welfare Education). The purpose of this study was to explore social welfare professional competencies, subject goals, teaching methods, and the participatory learning environment for the development of a competency-based social welfare curriculum. The findings are as follows. First, each university had been researching professional competencies individually. Second, the social welfare subjects tended to include all elements of knowledge, skills, and attitudes, and these goals were matched with professional competencies set by each university. Third, the guidelines for social welfare subjects provided various teaching methods to achieve the goals of the subject as well as a participatory learning environment based on discussion. However, it was difficult to determine whether the various teaching methods were effective in achieving core and professional competencies. Therefore, it is necessary for KCSWE to set up a standardized competency-based curriculum and research professional competencies based on social welfare, a curriculum and subjects according to their competencies, effective teaching methods, and a method for evaluating educational outcomes.

  • The nineteenth century was a watershed - the extreme point of difference in the style of fashion dress and in the roles men and women played in society. This conviction has its roots in the socioeconomic changes of the 19th century and the industrial revolution, and the new working bourgeoisie' value, fashion and taste were on the rise. The bourgeois, who was not considered as having infallible taste, was looking for its own style, while on the other hand it was competing with the nobility. Therefore bourgeois' own etiquette and taste were appeared. There was ideals which the middle classes were hungry for, and it became the basis of judging an individual. The bourgeois tried to get social approval and used fashion was the mean of it. Bourgeois women fashion has a funtion as a complete symbol of the status, wealth and leisure in a patriachal society. Not only the Bourgeois tried to control themselves and to achieve the virtue of moderation, chastity and obedience by the restrictive costume, but also extravagant and cumbersome dresses has a kind of compensative funtion against a sober and simple men's dress. There was a reformative movement to break out of the legal, economic and social restrictions within the confines of respectable Victorian Society. The process of reform was long and slow for not only did laws be changed but the barriers of prejudice in a society convinced of man s mental and physical superiority had to be overcome. But even though there were many difficulties, a small number of progressive women challenged the social recognition and role of women and decisively refused the restrictive and ostentative fashion. Victorian costume was also criticized in the medical and aesthetic aspect for their impracticality. As a result, more funtional and practical women's clothes has appeared, but it have resulted in a peculiar hybrid of traditional female attire in combination with the more uncomfortable aspects of men's clothes. However it was becoming an essential look for new women who were the equals of men and wanted to be treated as such.

  • With the advent of the 4th industrial revolution, autonomous driving technology is being commercialized in various industries. However, research on autonomous driving so far has focused on platforms with wheel-type platform. Research on a tracked platform is at a relatively inadequate step. Since the tracked platform has a different driving and steering method from the wheel-type platform, the existing research cannot be applied as it is. Therefore, a path-tracking algorithm suitable for a tracked platform is required. In this paper, we studied a path-tracking algorithm for a tracked platform based on a GPS sensor. The existing Pure Pursuit algorithm was applied in consideration of the characteristics of the tracked platform. And to compensate for "Cutting Corner", which is a disadvantage of the existing Pure Pursuit algorithm, an algorithm that changes the LAD according to the curvature of the path was developed. In the existing pure pursuit algorithm that used a tracked platform to drive a path including a right-angle turn, the RMS path error in the straight section was 0.1034 m and the RMS error in the turning section was measured to be 0.2787 m. On the other hand, in the variable LAD algorithm, the RMS path error in the straight section was 0.0987 m, and the RMS path error in the turning section was measured to be 0.1396 m. In the turning section, the RMS path error was reduced by 48.8971%. The validity of the algorithm was verified by measuring the path error by tracking the path using a tracked robot platform.

  • With the technology of the 4th Industrial Revolution integrated into the industry as a whole, digital transformation (DT) is becoming an innovative and essential element of corporate survival in the fashion industry, and it is expected that the paradigm shift in shopping will become an unavoidable reality, especially based on the AR. Therefore, in this study, the characteristics of augmented reality were presented separately as perceived realism, interaction, pleasure, and usability, and the influence of augmented reality by immersion parameters on the user's satisfaction and intended to reveal the relationship between satisfaction and usage through the characteristics of augmented reality. For the purpose of this study, a structured questionnaire was conducted, and the available 209 responses were collected and used for empirical analysis. The results of the empirical analysis are as follows. First, while immersion has the greatest effect on satisfaction, the effect on use intention has a stronger effect on satisfaction than immersion. This indicates that purchase occurs when the user's immersion leads to satisfaction, and when the satisfaction falls, the intention to use is also lowered. Second, interactivity, enjoyment, and ease of use among the various characteristics of fashion applications have a positive effect on immersion. Among them, ease of use had a strong effect on immersion. In light of this, it can be seen that ease of use should be considered first when creating an application based on augmented reality in the future fashion industry. However, the perceived reality is low in the degree of immersion, and the effect on satisfaction is also lowered, so it is difficult to be connected to intention. Considering that this study was conducted through indirect experience through video viewing, this study expects the development of research through a more practical research model in the future, as the impact is considered to be a relatively low measurement.

  • The article aims to making a comparison between traditional Korean and Western furniture metal handles to give the detail information of the handle terms by analyzing the related literature including internet and interviews. In terms of that, the Korean and Western metal handles are compared in the types, components, materials, methods, and terms affecting the development made by the craftsmen before the Industrial Revolution about the mid or late 18th century. As a result, first, ring and drop pull handles were mostly and wooden knobs were a little used to open the furniture doors and drawers. The Korean drop pulls, Deulswae, came out after the ring pulls, Gori, while the Western drops called loop or bail handles as well, came out before the ring pulls. Second, the components were composed by ring, Gori, loop or bail, Deulswae, Post, Baemok, washer, Baemokbatchim, and backplate, Deulswaebatchim. Most of the Western handles were fastened by the bolt and nut, while the post of two strips, Baemok, fastened the Korean metal handles. Third, the metal handles were created of brass and iron mostly, gilded gold and silver. Forth, the method were largely used by casting, engraving, forging, plating, and hammering in the Korean handles, and by casting, molding, engraving, and stamped in the Western handles. Finally, the terms such as "knobs, pulls, drops, ring and drop pulls, loop or bail handles, posts, washers, backplate, casting, molding, engraving, forging, plating, and stamped" were clarified by the two comparison in Korean and English.

  • Facing the 4th Industrial Revolution era, researches on artificial intelligence have become active and attempts have been made to apply machine learning in various fields. In the field of finance, Robo Advisor service, which analyze the market, make investment decisions and allocate assets instead of people, are rapidly expanding. The stock price prediction using the machine learning that has been carried out to date is mainly based on the prediction of the market index such as KOSPI, and utilizes technical data that is fundamental index or price derivative index using financial statement. However, most researches have proceeded without any explicit verification of the prediction rate of the learning data. In this study, we conducted an experiment to determine the degree of market prediction ability of basic indicators, technical indicators, and system risk indicators (AR) used in stock price prediction. First, we set the core parameters for each financial indicator and define the objective function reflecting the return and volatility. Then, an experiment was performed to extract the sample from the distribution of each parameter by the Markov chain Monte Carlo (MCMC) method and to find the optimum value to maximize the objective function. Since Robo Advisor is a commodity that trades financial instruments such as stocks and funds, it can not be utilized only by forecasting the market index. The sample for this experiment is data of 17 years of 1,500 stocks that have been listed in Korea for more than 5 years after listing. As a result of the experiment, it was possible to establish a meaningful trading strategy that exceeds the market return. This study can be utilized as a basis for the development of Robo Advisor products in that it includes a large proportion of listed stocks in Korea, rather than an experiment on a single index, and verifies market predictability of various financial indicators.

  • The purpose of this study is to construct a regional-sector-fishery-offshore and inshore fishery competitiveness index, examine the types and changes of competitiveness, and derive implications by processing data of the Survey on the Current Status of Offshore and Inshore Fishery from 2013 to 2020 for this study. The main results of this study can be summarized as follows. First, considering the competitiveness of offshore and inshore fishery by region and year, Jeonnam, Jeju, and Incheon were relatively competitive. Second, considering the competitiveness of inshore fishery by region and year, we found that Jeonnam, Chungnam, Jeonbuk, and Jeju were relatively competitive. Third, looking at the types of competitiveness based on the competitiveness index in the management sector of offshore and inshore fisheries by region and year, Ulsan, Jeonnam, and Gyeongbuk were relatively competitive between 2014 and 2020. Fourth, Jeonnam and Jeju were relatively competitive between 2014 and 2020 based on the competitiveness index in the fishing sector of offshore and inshore fisheries by region and year. Fifth, we found that Jeonnam, Jeju, and Chungnam were relatively strong in the competitiveness of offshore and inshore fishery, combining the offshore and inshore fishery indexes by region and year. The results of this study have some limitation on outlier treatment, grade assignment, and weight for aggregation, so research considering these needs to be done in the future. In conclusion, the results of this study which were derived objectively and scientifically in the era of the 4th industrial revolution, when evidence-based decision-making was becoming critical, are expected to help the central or local governments determine the priority of support projects or investments.

  • Since the recent COVID-19 pandemic, countries have been strengthening trade protection for their security, and the importance of securing strategic materials, such as food, is drawing attention. In addition to the cultural aspects, the global preference for food produced in Korea is increasing because of the Korean Wave. Thus, the Korean food industry can be developed into a high-value-added export food industry. Currently, Korea has a low self-sufficiency rate for foodstuffs apart from rice. Korea also suffers from problems arising from population decline, aging, rapid climate change, and various animal and plant diseases. It is necessary to develop technologies that can overcome the production structures highly dependent on the outside world of food and foster them into export-type system industries. The global agricultural industry-related technologies are actively being modified via data accumulation, e.g., environmental data, production information, and distribution and consumption information in climate and production facilities, and by actively expanding the introduction of the latest information and communication technologies such as big data and artificial intelligence. However, long-term research and investment should precede the field of living organisms. Compared to other industries, it is necessary to overcome poor production and labor environment investment efficiency in the food industry with respect to the production cost, equipment postmanagement, development tailored to the eye level of field workers, and service models suitable for production facilities of various sizes. This paper discusses the flow of domestic and international technologies that form the core issues of the site centered on the 4th Industrial Revolution in the field of agriculture, livestock, and fisheries. It also explains the environmental awareness production technologies centered on sustainable intelligence platforms that link climate change responses, optimization of energy costs, and mass production for unmanned production, distribution, and consumption using the unstructured data obtained based on detection and growth measurement data.
