This study analyzes the athleisure wear purchase status, wearing conditions, and design preferences of men in their 20s and 30s and provides basic data for the development of men's athleisure wear that reflects consumer preferences. An online survey was conducted on 200 men from August 23 to August 27, 2023. The questionnaire consisted of a total of 48 questions, including 8 questions about the respondent's general information, 19 questions about the purchase status of athleisure wear, 6 questions about the status of wearing athleisure wear, and 15 questions about athleisure wear design preferences. The survey results are as follows. The most common motive for exercise participation was 'maintaining health.' 'Nike' was the most preferred and purchased brand among athleisure wear brands, and the main place of purchase of athleisure wear was 'Internet and mobile shopping malls', reflecting the recent purchasing trend of the MZ generation. When purchasing athleisure wear, the most common selection criterion was 'design', followed by 'fitting comfort', 'possibility to use as daily wear', and 'price'. The most common route to obtain purchase information was 'Internet search', and the 'overall satisfaction' with athleisure wear was found to be satisfactory with an average of 3.83. The most common reason for wearing athleisure wear was 'because it is comfortable to do activities', followed by 'because it can be used as everyday wear'. Lastly, 'black', 'short-sleeved t-shirt', 'short length' sleeve, 'round neckline', 'waist length', and 'relaxed loose fit' were preferred for the top design, and 'black', 'shorts', 'full elastic type' waistband, 'regular fit that fits the body well' were preferred for the bottom design.

The purpose of this study was to evaluate the general characteristics, complications and level of social adaptation of spinal cord injured patients. The subjects were one hundred forty five members who were inpatients or outpatients from October 1, 2004 to April 30, 2005 in general hospitals and municipal welfare centers for the handicapped located in the metropolitan city of Gwangju. The following results were obtained using Modified Barthel Index (MBI). 1) Gender distribution was 77.9% male and 22.1% female. The mean age at the time of injury was 35.4 and the mean age during the study was 44.2. 2) The degree of paralysis among the subjects was as follows: 49.0% had complete paralysis and 51.0% suffered incomplete paralysis. The most frequently injured lesion among the subjects was cervical (49.0%), followed by thoracic (35.9%), and lumbar (15.2%). 3) The mean MBI score was 63.5. There was statistically significant difference in the MBI score in the relation between complete and incomplete paralysis, the relation between cervical, thoracic, and lumbar injury, and the relation between a recovery period of less than three years and more than three years according to the characteristics of injury (p<.05). 4) There was statistically significant difference in the MBI score of subjects who had complications concerning spasticity, deformity, urinary tract infection, and sexual dysfunction (p<.05). 5) The most serious emotional pain after spinal cord injury resulted from economic issues, which affected 35.2% of the subjects. The group having a shorter recovery period after spinal cord injury complained of psychological matters, the group having a longer recovery period complained about the surrounding environment (lack of convenient facilities), suggesting statistically significant difference (p<.05). 6) The most common activities of the group with injuries more than ten years old included meeting schoolmates and working, while most common activities of the group with injuries less than three years old included attending religious functions and miscellaneous others (watching TV, spending time with family), suggesting statistically significant difference (p<.05).

The purpose of this study was to examine the value of children in South and North Korea and to identify the similarities and differences in value orientations related to children and curriculum in child-care and education. The secondary data including 2013 research report on the South Korean consciousness and values, the Familial Law Act and the Child Welfare Act of South Korea, the Familial Law Act and the Law of Nursing and Upbringing of Children in North Korea, and a series of Choson-yeosung magazines in North Korea were analyzed. Results showed that first, it was common that both of social and psychological values of children were found, but the psychological values were more prevalent in the South and the social values were more dominant in the North. Second, parents in both cultures publically agreed that parenting should promote the development of the whole child. However, parents in the South were inclined to support happiness and personal achievement of children, whilst parents in the North were likely to reinforce ideology education producing a pillar for socialism. Third, it was common that both parents of the South and the North were primarily responsible for child-rearing, but the role of government in child-rearing was more emphasized in the North. Lastly, supporting daily routine activities, communication skills, and art activities were included in child-care and education programs in both cultures. However, communication skills and social relationship were emphasized in programs of the South, whilst ideology education was the most important components in program of the North. The strategies for understanding differences in the value of children between the South and the North after unification were discussed.

The purpose of this study is to investigate household Items and storage of kitchen and to suggest basic data for the desirable storage space. For the study, the samples were taken from 30 families living in 3-bedroom apartment. The personal interview and physical trace method were used to analyze the types and quantities of household Items and the storage conditions in kitchen furniture. The result was as follows : first, a total of 210 types of household Items were found in the kitchen, and the items ranged widely in purpose, from cooking and dining tools, hygiene products, and general household goods, which indicate that a variety activities in addition to cooking and eating are performed in the kitchen. Second, regarding the quantities of household Items, the majority of them were used for cooking and dining. Also the types and quantities of household Items varied according to the age of the child. Third, regarding storage of household Items in the kitchen by furniture type, the majority of the items were stored in the wall cabinets, base cabinets, and countertops and, as a storage method, simple 'placement' was most common. This suggests there is lack of three-dimensional storage in the kitchen. The findings show activities and storage in the kitchen space vary according to the age of the child, and household Items are stored by using several common methods.

Currently many companies are interested in reduction of the carbon emissions associated with their supply chain activities such as transportation and operations. Operational decisions, such as modifications in order quantities could an effective way in reducing carbon emissions in the supply chain. Cap-and-trade regulation, sometimes called emissions trading, is a market-based tool to limit greenhouse gas emissions. Under cap-and-trade regulation, emission credits are allocated to the firms and the firms trades emissions under cap-and-trade schemes. In this paper, we propose a single-manufacturer single-buyer two-echelon supply chain problem under the cap-and-trade mechanism incorporating the carbon emissions caused by transportation and warehousing activities where a single manufacturer produces a family of items in order to deliver a family of items to a single buyer at a fixed interval of time for effective implementation of Just-In-Time (JIT) Purchasing. An integrated multi-product lot-splitting model of facilitating multiple shipments in small lots between buyer and manufacturer is developed in a JIT Purchasing environment. Also, an iterative heuristic algorithm is developed to derive the common order interval, the number of intervals for each product and the number of shipments between the buyer and the manufacturer during the common interval. A numerical example is given to illustrate the savings in reduction of total cost and carbon emissions by the inventory model incorporating cap-and-trade mechanism compared to the classical inventory model. The proposed inventory model could be useful for the practical solution of two-echelon supply chain inventory problem under cap-and-trade mechanism.

Objectives: Most drug interactions are attributed to the inhibition or induction of the activity of cytochrome P450s (CYP450). Although the regulation of CYP450s by drugs has been widely reported, there have been few studies on influence of traditional herbal formulas on the drug-metabolizing enzymes. Because herbal formulas have been used traditionally to treat various diseases and because herb-drug interactions are crucial factors determining therapeutic efficacies, a systematic evaluation of the effects of herbal formulas is important. Methods: The effects of Galgeun-tang (GGT, gegen tang), Gumiganghwal-tang (GMGHT, jiuweiqianghuo tang), Insampaedok-san (ISPDS, renshenbaidu powder), Samsoeum (SSE, shensu drink), Socheongryong-tang (SCRT, xiaoqinglong-tang) and Sosiho-tang (SSHT, xiaochaihu tang) that are traditional herbal formulas used to treat common cold, on drug-metabolizing enzymes were evaluated through an in vitro CYP3A4, CYP2D6, CYP2C19 and CYP2E1 inhibition assay to assess its interaction potential with synthetic drugs. The inhibitory effects of herbal formulas were characterized with $IC_{50}$ values. Results: These six herbal formulas inhibited the activities of CYP3A4, 2C19, 2D6 and 2E1, in a concentration-dependent manner. Among the six herbal formulas, GGT critically inhibited CYP2C19, CYP2D6 and CYP2E1. GMGHT also inhibited CYP2D6 and CYP2E1 to a greater extent than the other CYP450 isozymes. Additionally, SSE and SSHT may change the effects of medicines that depend primarily on the CYP2C19 and CYP2E1 pathways. On the other hand, ISPDS and SCRT were not inhibited CYP3A4, CYP2C19, CYP2D6 and CYP2E1-mediated metabolism. Conclusions: These findings provide useful information regarding the safety and effectiveness of herbal formulas.

이 연구에서는 영재교육종합 데이터베이스(GED)에서 제공하는 초등 과학영재교육 프로그램 수상작을 과학적 창의성 관점에서 분석하였다. 이를 위해 해당 분석 기준을 개발한 뒤 우수 프로그램 55개에 포함된 840개의 탐구활동을 분석하였다. 연구 결과, 과학적 창의성 요소 5가지 중, '과학적 탐구기능', '과학 지식 내용', '창의적 사고'가 많이 포함되었다. 하지만 '문제해결력'과 '공통 요소'는 비교적 적게 포함되어 있었다. 통합의 측면에서는 2가지 요소의 통합과 3가지 요소의 통합이 자주 나타났으며, 통합이 없는 유형도 자주 나타났다. 4가지 요소의 통합이나 5가지 요소의 통합은 적게 나타났다. '과학 지식내용', '과학적 탐구기능', '창의적 사고' 등이 다른 요소들과 함께 통합되는 빈도가 높았다. 그러나 '공통 요소' 또는 '문제해결력'이 다른 요소와 통합되는 경우는 적게 나타났다. 이에 대한 교육적 시사점을 논하였다.
