Recently, youth unemployment is not a mere economic problem in Korea. It could be developed into a serious social problem. It has been long since youth unemployment rate was more than double in total unemployment rate, which stood at 3.5 percent in 2005 and then the inactivity among the younger job-seekers is appearing to be chronic. Hence, this paper examines the status and causes of the youth unemployment problem and studies the possibility to apply the Demand-Supply Chain Management to the problem.

Gangform is used as exterior wall forms in the most of apartments. Existing system forms developed for high-rise building, RCS and ACS, are too heavy and over-designed to be applied to general apartments, leading to higher costs. A more simplified rail Gangform(R/GF) is also used, but it depends entirely on T/C for the lift like Gangform. The T/C's legal inactivity time for moving Gangform and materials has increased, and the higher allowances have to be paid for overtime work, thus causing to the cost increase and time delay. Therefore, this study aims to develop an automated Gangform climbing system that can be used universally and economically in apartment houses. The use of the development system is expected to improve the safety of Gangform operations and reduce the workload on T/C.

Sarcopenia is a condition in which muscle mass and strength are decreased and muscle function is impaired. It is an indicator of frailty and loss of independence in older adults. It is also associated with increased physical disability, which increases the risk of falls. As a multifactorial disease, sarcopenia is caused by a combination of factors including aging, hormonal changes, nutritional deficiencies, and physical inactivity. Understanding the underlying pathophysiology of sarcopenia and identifying its different causes is critical to developing effective prevention and treatment strategies. This review summarizes the pathophysiology, consequences, diagnostic methods, and multidisciplinary approaches to sarcopenia.

Physical inactivity may an important outcome in the prognosis of breast cancer. Physical activity levels decrease significantly for breast cancer patients following the treatment and remain low after oncology treatment is completed. The aim of this study was to determine physical activity levels and to examine associations among physical activity, comorbidity, functional capacity, peripheral muscle strength, and psychosocial status in breast cancer patients. Forty breast cancer survivors were included in this study. Demographic and clinical characteristics were recorded. Physical activity was assessed with a short form of the International Physical Activity Questionnaire (IPAQ). We defined comorbid diseases according to the Charlson Comorbidity Index (CCI). Functional capacity was evaluated with a six-minute walk test (6MWT). Peripheral muscle strength was measured for quadriceps femoris muscle with a hand-held dynamometer. Psychosocial status was measured with the Hospital Anxiety Depression Scale (HADS). Forty percent of patients were inactive. The IPAQ total score was significantly related with quadriceps muscle strength (r=0.492; p<0.001) and HADS depression score (r=0.341; p<0.05). Marked correlations were also observed between IPAQ walking score and quadriceps muscle strength (r=0.449; p<0.001), HADS depression score (r=0.341; p<0.05), and CCI (r=-0.433; p<0.001). The CCI score was also markedly associated with quadriceps muscle strength (r=-0.413; p<0.001). 6MWT distance was not significantly correlated with any of the parameters. Regression analyses revealed that psychosocial status and peripheral muscle strength were significant predictors of physical activity estimated with the IPAQ short form and when combined, they explained 35% of the variance. Comorbidities, peripheral muscle strength and psychosocial status partially explain the variability of physical activity level in breast cancer survivors. These results suggest that physical inactivity contributes to worsening health in breast cancer survivors.

In this study, we set an optimum blanching condition as a pretreatment condition to freeze welsh onion (Allium fistulosum L.) for the purpose of preserving the cooking material for long-term usage. With higher blanching temperature and longer processing time, the Hunter color values and the hardness of welsh onion tended to decrease, which confirmed softening of the tissue. Compared to before blanching, total bacterial counts decreased to near 2 log scale, whereas coliforms were not detected or decreased to a 1-2 log scale. Blanching by heating at 100$^{\circ}C$ for 5 min decreased peroxidase inactivity to more than 94%, whereas only 47% of the inactivity was achieved at 80$^{\circ}C$ for 1 min. The sensory evaluation for the blanched and defrosted welsh onion showed that the group blanched at 80$^{\circ}C$ for 1 min was preferred significantly (p<0.05).

This research examines the recognition of nature as identified by Zhuangzi through the man of truth. Zhuangzi defines inactivity as an act of nature and personifies it as the man of truth, a holy man who achieves salvation. It is the stage that is united with nature by breaking out of secular restriction and achieving the absolute liberal spirit. The man of truth is the origin enabling all the acts of nature. And since the existence of all living things is connected, the change of life and death complies with the operation of nature. It is an irresistible destiny for all human beings. Therefore, the duty of nature recognizes the life and death of all creation into a single perspective. In this sense, the feelings of joy and sorrow that human beings feel are unnecessary. When following the duty of nature and destiny, which is to break out of secular desire and empty the mind, it is possible to go to the stage of futility and enjoy a silent and comfortable life. Zhuangzi explains it as living free from worldly cares, which is the stage of 'Soyoyoo(逍遙遊)'. In this thesis, the principles of courtesy and the virtue of Confucianism are stated and are contrary to the concept of futility asserted by Zhuangzi. But, a different approach could be attempted which recognizes a superman who is even more evolved from the man of truth. The philosophical ideology of Zhuangzi could be a necessary factor for modern people and his oriental natural spirit should be highly appreciated.

Objectives: This study explored the prevalence and predictors of alcohol and cannabis co-use among 9263 Filipino adolescents, using data from the 2019 Global School-based Student Health Survey (GSHS). Methods: We conducted a cross-sectional secondary analysis of the GSHS, targeting adolescents aged 13-17 years and excluding cases with incomplete data on alcohol and cannabis use. Our analysis employed the bivariate chi-square test of independence and multivariable logistic regression using Stata version 18 to identify significant predictors of co-use, with a p-value threshold set at 0.05. Results: The weighted prevalence of co-users was 4.2% (95% confidence interval [CI], 3.4 to 5.3). Significant predictors included male sex (adjusted odds ratio [aOR], 4.50; 95% CI, 3.31 to 6.10; p<0.001) and being in a lower academic year, specifically grade 7 (aOR, 4.08; 95% CI, 2.39 to 6.99; p<0.001) and grade 8 (aOR, 2.20; 95% CI, 1.30 to 3.72; p=0.003). Poor sleep quality was also a significant predictor (aOR, 1.77; 95% CI, 1.29 to 2.44; p<0.001), as was a history of attempted suicide (aOR, 5.31; 95% CI, 4.00 to 7.06; p<0.001). Physical inactivity was associated with lower odds of co-use (aOR, 0.45; 95% CI, 0.33 to 0.62; p<0.001). Additionally, non-attendance of physical education classes (aOR, 1.48; 95% CI, 1.06 to 2.05; p=0.021), infrequent unapproved parental checks (aOR, 1.37; 95% CI, 1.04 to 1.80; p=0.024), and lower parental awareness of free-time activities (aOR, 0.63; 95% CI, 0.45 to 0.87; p=0.005) were associated with higher odds of co-use. Factors not significantly linked to co-use included age group, being in grade 9, always feeling lonely, having no close friends, being bullied outside school, and whether a parent or guardian understood the adolescent's worries. Conclusions: The findings highlight the critical need for comprehensive interventions in the Philippines, addressing not only physical inactivity and parental monitoring but also focusing on sex, academic grade, participation in physical education classes, sleep quality, and suicide attempt history, to effectively reduce alcohol and cannabis co-use among adolescents.

The present study focused on the color of clothing for elderly Korean women, from the viewpoint of helping elderly people live more interesting lives with regard to their clothing, considering that the Korean society will become elderly-oriented in the near future. We took photographs of the elderly served as the models, displayed them on a computer screen, and produced 75 colors of the clothing in the elderly using computer graphics. The 75 colors were evaluated by 2 groups, one of elderly Korean woman group and a group of female students. We compared the ideal colors for and the colors actually worn by elderly people. The evaluation of the clothing colors for elderly women differed between the elderly woman group and the female student group. Analysis of images of the clothing colors selected by the elderly women showed that they attach importance to elegance when selecting clothing colors and have a strong desire to become active. The images held by female students concerning ideal clothing colors for elderly women closely pertained to commonness and inactivity.

A discontinuous reception (DRX) operation is included in the Long Term Evolution (LTE) system to achieve power saving and prolonged battery life of the user equipment. An improvement in DRX power saving usually leads to a potential increase in the packet delay. An optimum DRX configuration depends on the current traffic, which is not easy to estimate accurately, particularly for non-real-time applications. In this paper, we propose a novel way to vary the DRX cycle length, avoiding a continuous estimation of the data traffic when only non-real-time applications are running with no active real-time applications. Because a small delay in non-real-time traffic does not essentially impact the user's experience adversely, we deliberately allow a limited amount of delay in our proposal to attain a significant improvement in power saving. Our proposal also improves the delay in service resumption after a long period of inactivity. We use a stochastic analysis assuming an M/G/1 queue to validate this improvement.
