  • This study attempted to explore the realization and research direction of a successful metaverse environment in the future by analyzing international research trends of the metaverse using topic modeling. A total of 208 papers among WoS and ScienceDirect papers using metaverse as keywords were selected, and quantitative frequency analysis and topic modeling were performed. As a result, it was confirmed that research has rapidly increased after 2022. The main keywords of the research topics were 'second', 'life', 'learning', 'reality', 'metaverse', 'virtual', 'blockchain', 'nft', 'medical', 'avatar', etc. The topic keywords 'Second life & Education' and 'Virtual Reality & Medical' accounted for a large proportion of 57%, followed by 'Blockchain & Cryptocurrency', 'Avatar & Interaction', and 'Sensing and Device'. As a result of semantic analysis, current metaverse research is focused on application and utilization, and research on underlying technologies and devices is also active. Therefore, it is necessary to identify the commonalities and differences between domestic and foreign studies, and to study the application method considering the domestic environment. In addition, new jurisprudence research is more necessary along with predicting new problems. It is expected that the results of study will provide the right research direction for domestic researchers in the era of digital transformation and contribute to the realization of a digital society.

  • 국내산과 중국산 능이에 대한 다량미네랄, 미량미네랄 및 유해중금속 함량을 비교하여 원산지 판별 가능성을 분석하고자 하였다. 능이의 미네랄 함량은 원자흡광광도계(Atomic absorption spectrophotometer, AAS) 및 유도결합플라즈마 질량분석기(Inductively coupled plasma mass spectrometer, ICP-MS)를 사용하여 분석하였다. 국내산 능이의 Na, Mg, K 및 Ca 함량은 각각 170.3±44.0 mg/kg, 81.3±20.8 mg/kg, 1,123.8±274.3 mg/kg 및 12.1± 4.1 mg/kg으로 분석되었으며, 중국산 능이는 각각 112.2±40.8 mg/kg, 297.8±20.9 mg/kg, 10,938.4±2,914.1 mg/kg 및 52.5±27.7 mg/kg으로 분석되어 유의적 차이가 있는 것으로 나타났다. 미량미네랄 및 유해중금속 함량은 유의적 차이가 나타나지 않았다. 따라서 능이의 원산지 판별 지표 확립을 위하여 향후 다수의 국내산 및 중국산 능이를 사용한 Na, Mg, K 및 Ca 함량 비교분석이 필요한 것으로 판단되었다.

  • Objectives: This study was conducted to examine the current status of traditional Korean medicine studies on chronic prostatitis in Korea, identify deficiencies, and suggest future medicine research methods to lay the foundation for traditional Korean medicine treatment. Methods: All domestic clinical research papers on the traditional Korean treatment of chronic prostatitis were selected from the literature published until October 2023 in three domestic databases. A total of 13 selected research data were classified into clinical research papers. Results: In clinical research papers, the basis for the diagnosis of cases was clinical symptoms through medical history listening and diagnosis through past visits to hospitals. The average treatment period was 7 weeks, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. Conclusions: This study included all domestic clinical research papers on chronic prostatitis to identify research trends in the Korean oriental medicine community. Based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

  • This thesis provided basic data of the domestic leggings industry. For the purpose of comparative analysis, the sales status and consumer preference status of domestic leggings brands were selected, and the three companies, X*xymix, A*dar, and M*laware, which occupy the top positions by domestic leggings brand rankings Therefore, from 2018 to 2020, the market size of leggings items is identified with reference to the sales status and consumer preference status data, and the status of consumer preference is analyzed. As a result of the survey analysis, X*xymix, A*dar, and M*laware, which rank high in consumer preference, operate a separate men's leggings line from leggings targeting young women who mainly focus on yoga, pilates, and fitness exercises. As the age increased, the demand for leggings expanded to the middle-aged. Therefore, it is believed that the segmentation of leggings is made according to the diversifying types of exercise, and as the age group in demand for leggings is expanded, continuous research on market segmentation for aqua leggings necessary for aqua exercise that can exercise without straining the body.

  • In the 1960s, rapid urbanization and industrialization created the social atmosphere of individualism in Korea. Individualism has weakened social ties, led to the breakdown of communities, and caused various social problems. So, the paradigm is shifting to a shared society and there are moves to seek ways to solve social problems through community. As part of the initiative, the value and importance of common space in multi-unit dwelling, the typical Korean housing type, is increasing. Thus, the purpose of this study is to identify the trends of domestic research about common space, to assess the current state of domestic academic world and explore the future plans of the common space. The content analysis method was mainly used and statistics were additionally used to analyze 172 preceding research. As a result, research on common spaces showed a steady increase to the current time. And research was being diversified in the field of publishing journals, research contents, research methods and facilities. Until now, most studies have focused on improvement of plan and the quality of common space by identifying the attitude survey, space planning, and the actual situation. Thus many more studies about proper way to operate and manage common space need to be conducted. it is considered that the common space will develop more efficiently. The study is expected to be used as groundwork for the development of the common space and serve as concrete data to show future development directions.

  • The purpose of this study is to find method to meet the greater retailer's supplier assessment requirement So, this study analyze the greater retailer's requirement for supplier assesment and research global standard which is used instead of supplier assessment requirement that is recognized by global retailers initiative. Next, this study analyze domestic aquaculture certification requirement and compare the global standard with the domestic requirement by using The Most Similar Systems Design. As a result, this comparing has founded all of two domestic certifications are similar to global standard's Good Aquaculture Practice module but those are a little bit different from System Element module. Therefore, this study suggest tree alternative. First, make up for the weak points in the current domestic aquaculture certification system. Second, the introduction of global aquaculture management system certification as supporting by government. Third, development of new standard in accordance with global food standard. This study has major implications for research into development of domestic aquaculture standard.
