Reselling, an activity of purchasing high-scarcity products and selling them back at high prices, has gained popularity among those in their 20s and 30s in recent years. This study examines the resell activity process of the MZ generation using the online second-hand platform and its inherent meaning. Interviews with 15 participants in their 20s and 30s showed that respondents have four purchase stages: being influenced by social media, collecting and comparing information using various social media, purchasing efforts, and post-purchase behavior. The research derived three inherent meanings of resell activities: (1) means of self-presentation and differentiation, (2) confirmation of investment skills and aptitude to lead fashion trends, and (3) pleasure of consumption. Respondents indicated meeting self-satisfaction through public selfies on social media. In addition, they emphasized the empirical pleasure during the buying journey by collecting product information, comparing prices, and negotiating with buyers. Our findings confirm the spread of resell activities from minority groups to enthusiastic youth. This study is significant for focusing on fashion products that attract attention in the resell market and examining the respondents' consumption experiences from various perspectives.

Objectives: This study was conducted to identify the correlation between belief in hand hygiene, activities and related hand hygiene performance rates among dental staff. Methods: This study was based on the evaluation of 329 dental practitioners, including dental hygienists who work at dental clinics, dental hospitals, general and university dental hospitals in Seoul, Gyeonggi-do Province, and Incheon. The questionnaire consisted of a total of 46 questions, including 7 questions on general characteristics, and 25 questions on hand hygiene beliefs, and 5 questions on hand hygiene activities, and 9 questions on hand hygiene practices. This study used 291 subjects for the final analysis, excluding subjects who had provided incomplete or inappropriate responses to the questionnaire. The collected data were analyzed using an independent t-test, ANOVA, $x^2$ test, correlation analysis, and multiple linear regression analysis, where p-values of <0.05 were considered statistically significant. Results: Longer clinical career was associated with a significant increase in behavior and norm beliefs, but no sequential difference in control beliefs. The hand hygiene performance was higher in staff at larger hospitals after contact with pollutants and contaminated environments. Higher age was associated with a significant increase in hand hygiene performance rates, but profession was not statistically significant in the performance rate of hand hygiene. The hand hygiene performance rate was ranked higher among those with average work hours per week of greater than 8 hours followed by those who worked fewer than 8 hours. Fewer work hours per week, a stronger belief in hand hygiene, less frequent exposure to contaminated environments, and a greater number of hand hygiene performance had a positive effect on higher hand hygiene performance rates. Conclusions: In order to increase the hand hygiene performance rate of dental practitioners, it is considered that required time for hand washing should be ensured sufficiently. Proper usage of hand sanitizers should also be promoted efficiently.

Purpose: In order to examine difference in the activity of potential of spinal neurons and cortical neurons according to muscle contraction type in post stroke hemiplegic subjects and healthy subjects, the present study conducted an experiment as follows. Methods: The subjects in the experimental group were 17 left-side hemiplegic subjects (9 female, 8 male; mean age, 63.41$\pm$9.86 years) with the right hand as the dominant hand selected among post stroke hemiplegic subjects, and 17 age matched healthy control subjects (10 female, 7 male; mean age, 64.12$\pm$12.07 years). Movement-related cortical potentials (MRCPs) were measured using surface electromyography and electroencephalography while concentric and eccentric movements were made alternately. Results: As to the pattern of the activity of MRCP, which indicates the activity of motor cortical neurons, we found that the amplitude is high (p<0.01), the length of excitement is short (p<0.01) and the ascending gradient of amplitude to the peak increases (p<0.05) in post stroke hemiplegic subjects' lesion sites different from healthy subjects. Conclusion: The activity of cortical neurons was no difference in activity according to contraction type was observed in post stroke hemiplegic subjects' lesion sites. This suggests that there is no distinction in the activity of cortical neurons between concentric contraction and eccentric contraction. Accordingly, if post stroke hemiplegic subjects' activity of motor cortex is analyzed by measuring MRCPs, it is considered useful in research on neural plasticity or as a ground of clinical effects in the area of physical therapy for the central nervous system.

군수품 품질보증을 위한 정부품보활동계획 수립의 기반이 되는 위험식별(Risk Identification)은 품질보증활동의 근간이 되는 업무로서, 위험을 구체적으로 파악하여 반영하는 활동이다. 그러나, 현재의 위험도평가 방법은 규격서 등에 명시된 제품에 대한 기능요구조건을 위주로 작성함에 따라 제조프로세스 측면에서의 위험식별 및 반영이 부족할 우려가 있으며, 또한 품보원의 개인적인 판단 즉 과거 경험, 노하우 등 정성적인 판단으로 결정할 우려가 있기 때문에 위험식별의 객관성과 전문성의 보완을 위해 정량적인 자료에 의한 판단 기준이 필요하게 되었다. 이러한 문제점에 대한 해결방안으로 FMEA 결과를 위험식별의 결과로 활용하는 방안을 강구하였다. FMEA는 현 제조공정을 기준으로 잠재적 고장형태를 분석하고 고장에 대한 영향 분석을 수행하므로 FMEA의 분석결과를 반영하여 위험식별을 하게 되면, 더욱 공정하고 객관적으로 정부품보활동 계획이 도출될 것으로 예상되었다. 본 논문에서는 양산단계 위험식별 업무를 강화시킬 수 있는 방안으로 세열수류탄에 대한 FMEA 수행내용과 이를 토대로 군수품 품보활동계획수립에 대한 적용방안을 모색하는데 그 작성 목적이 있다.
