The purpose of this study was to examine the use of different sorts of Korean traditional liquor among male and female adults in Seoul and Gyeonggi province, their awareness of them and their preference in an effort to discuss what problems Korean traditional liquors were faced with and how they could gain popularity among people in general. First, It is investigated of drinking frequency by gender, 51.3 percent of the male adults drunk once or twice a week, and 33.2 percent of the female adults drunk once or twice a month. Thus, the men drunk more often than the women. By age, the adults who were in their 20s and 30s were far different from those who were in their 50s above in drinking frequency. Second, regarding what kind of liquor they enjoyed, the men enjoyed Soju the most, followed by beer and traditional liquors. The women enjoyed beer the most, followed by Soju and wine. The favorite liquor of the men was Soju, followed by beer and traditional liquor, and the women most liked for beer, followed by wine and Soju. The female adults preferred low-proof liquor more than the male adults. Third, concerning their awareness of traditional liquor, Andong-soju was most widely viewed as traditional liquor, which were followed by Munbaeju, Gyeongju-gyodongbeopju, Gyeongju-beopju, Gukhwaju, Ssal- makgeolri, and Geumsan-insamju. Overall, they were rarely aware what traditional liquor was. Fourth, as to purchase experience, the men and the older people had more experience to buy traditional drinks than the women and the younger ones. Fifth, as for anju (dishes for traditional drinks), they believed that panfried food and Kimchi should be served with coarse liquor. Panfried and streamed dishes were considered to be good complements to Takju (rice wine) and Cheongju (clear strained rice wine), and pot stew and soup were looked upon as good complements to distilled liquor. The above-mentioned findings illustrated that in order to step up the development of the traditional liquor industry, perpetual research efforts should be put into adding new tastes to unique traditional liquor drinks. And it's required to commercialize those drinks, and multiple P.R. and marketing strategies should be prepared to promote their sales.

The main purposes of the study were to identify factors affecting health-related quality of life of elderly stroke survivors, and to suggest social work interventions for improving their quality of life. The participants were 328 elderly stroke survivors over 55 years old recruited from 18 long-term care hospitals and 13 nursing care facilities in Chung-Nam Province, Korea. The data was collected through a direct survey method from Dec. 16, 2008 to Jan. 17, 2009. Statistical analysis revealed that the overall health-related quality of life among participants was relatively low, especially in the social relationships domain. As a result of hierarchical multiple regression analysis, depression emerged as the most significant predictor of elderly stroke survivors' health-related quality of life, followed by financial burden in future, activities of daily living, acceptance of disability, comorbidity, and major financial supporter(spouse). Health-related quality of life of elderly stroke survivors in long-term care facilities was affected by a variety of variables from disease-related factors to environmental ones. Particularly psychosocial variables were the most powerful factors to predict HRQOL of elderly stroke survivors. Based on the results, social work implications were discussed in the context of developing clinical strategies to alleviate elderly stroke survivors' health-related quality of life in long-term care facilities. Living with chronic illness and disability is a great challenge to the elderly. Most of all long-term residence in care facilities can cause deterioration of quality of life in old age. From now on, studies on health-related quality of life of elderly with chronic illness and disability should be activated in social work field.

The present study examined the impact of work stress and job satisfaction on intention to leave among staff including social workers, nurses, and care workers. The study subject included 235 staff in a welfare organization that provides long-term care services. Data was analyzed using multiple linear regression. The findings of the study show that work stress and job satisfaction affect intention to leave in the context of welfare organizations. Demographic variables were not the main focus of this study and thus these results are incidental. Staff with higher levels of work stress were more likely to think about leaving, while those with grater job satisfaction were less likely. There were several limitations in this study. Generalizability of the findings are limited to staff working in the province of Jeonnam. The results have important implications for the development of strategies to minimize turnover intention in long-term care. Reducing the intent to leave is desirable for issues of both cost reduction and quality of care. Managers could perhaps start to consider decreasing work overload assigned to staff. This study also provides some insight into the work status of new staff. Clearly this finding needs to be explored in further research studies. A more comprehensive model is likely required to adequately explain intention to leave the job.

Purpose The purpose of this study was to examine the relationship between physical activities, sleep disturbance, and health related quality of life (HRQOL) in patients with chronic obstructive pulmonary disease (COPD). Methods A descriptive survey design used pretest dataset of COPD symptom management intervention study (N=245). Measures included the international physical activity questionnaire, the COPD and asthma sleep impact scale, and the St. George's respiratory questionnaire of HRQOL. The data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficients, and simultaneous multiple regression by the SPSS WIN 18.0 program. Results The mean scores (SD) of HRQOL and sleep disturbance were 36.04 (19.43) and 14.33 (6.20), respectively. About 32% of participants were physically inactive. The multivariate approach showed the patients who have more sleep disturbance (β=.27), lower levels of FEV1 % predicted (β=-.23), lower physical activities (β=-.19), lower household income (β=-.16), and diagnosed longer than 5 years (β=.14) reported lower HRQOL (R²=.34). Conclusion The findings of this study suggest that improving the quality of sleep and physical activities can be efficient strategies for HRQOL in patients with COPD. Future research in enhancing HRQOL through improving sleep quality and physical activities is needed.

Global discussions are actively underway regarding the introduction of urban air mobility (UAM) to revolutionize the paradigm in the innovative mobility industry. While research related to airspace, vertiports, navigation, and communication pertinent to Korean UAM is actively pursued by relevant research institutions, there is a significant dearth in studies focusing on establishing concepts for operational management by UAM operators and formulating control procedures. The commercialization of UAM necessitates the establishment of standardized operational management concepts, pivotal as benchmarks for the individual system development among multiple UAM operators. This paper analyzes UAM exceptional law, operational readiness, existing regulations pertaining to commercial and rotary-wing aircraft, and proposes suitable approaches to formulate domestic low-density operational management and control procedures. By presenting strategies for conceptualizing operational management and control procedures in the initial low-density environment for UAM, this paper aspires to contribute to future trail operations and the wider adoption of UAM.

Sepsis is a systemic inflammatory response, with manifestations in multiple organs by pathogenic infection. Currently, there are no promising therapeutic strategies. Signal transducer and activator of transcription 3 (STAT3) is a cell signaling transcription factor. Niclosamide is an anti-helminthic drug approved by the Food and Drug Administration (FDA) as a potential STAT3 inhibitor. C57BL/6 mice were treated with an intraperitoneal injection of lipopolysaccharide (LPS). Niclosamide was administered orally 2 hours after the LPS injection. This study found that Niclosamide improved the survival and lung injury of LPS-induced mice. Niclosamide decreased the levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in serum. The effects of Niclosamide on phosphoinositide 3-kinase (PI3K), AKT, nuclear factor-κB (NF-κB), and STAT3 signaling pathways were determined in the lung tissue by immunoblot analysis. Niclosamide reduced phosphorylation of PI3K, AKT, NF-κB, and STAT3 significantly. Furthermore, it reduced the phosphorylation of STAT3 by LPS stimulation in RAW 264.7 macrophages. Niclosamide also reduced the LPS-stimulated expression of proinflammatory mediators, including IL-6, TNF-α, and IL-1β. Niclosamide provides a new therapeutic strategy for murine sepsis models by suppressing the inflammatory response through STAT3 inhibition.

The monitoring of environmental information (e.g. noise, dust, vibration, temperature, humidity) is crucial to the safe and sustainable operation of a construction site. However, commercial sensors exhibit certain drawbacks when applied on-site. First, the installation cost is prohibitively high. Second, these sensors have been engineered without considering the rugged and harsh conditions of a construction site, resulting in error-prone sensing. Third, construction sites are compelled to allocate additional resources in terms of manpower, expenses, and physical spaces to accommodate individual sensors. This research developed an integrated sensing module to measure the environmental information in construction site. The sensing module slashes the installation cost to 3.3%, is robust enough to harsh and outdoor sites, and consolidates multiple sensors into a single unit. The sensing module also supports GPS, LTE, and real-time sensing. The evaluation showed remarkable results including 97.5% accuracy and 99.9% precision in noise measurement, an 89.7% accuracy in dust measurement, and a 93.5% reliability in data transmission. This research empowers the collection of substantial volumes and high-quality environmental data from construction sites, providing invaluable support to decision-making process. These encompass objective regulatory compliance checking, simulations of environmental data dispersion, and the development of environmental mitigation strategies.

This study aims to analyze low-performing high school students' difficulties in constructed response (CR) mathematics assessments and explore ways to use writing activities to support student learning. The participants took CR assessments, engaged in guided writing activities across 15 lessons, and provided responses to our interviews. The study identified 20 types of student difficulties, which were sorted into two main categories: "mathematical difficulties" and "CR difficulties." The difficult nature of mathematics as a school subject included a lack of understanding of mathematical concepts, students' difficulty with mathematical symbols and notations, and struggles with word problems. Challenges specific to CR assessments included students' difficulties arising from the testing conditions unlike those of multiple-choice items, and included issues related to constructing appropriate responses and psychological barriers. To address these challenges in CR assessments, the study conducted guided writing activities as an intervention, through which six themes were identified: (1) internalization of mathematical concepts, (2) mathematical thinking through relational understanding, (3) diverse problem-solving methods, (4) use of mathematical symbols, (5) reflective thinking, and (6) strategies to overcome psychological barriers.
