Because of the governments policy to promise the cultural homesickness of citizens, national and public culture centers are under construction all over the country. The interest of watching plays are increasing. But the existing culture center's facilities operating in the construction of emphasized. It's made up of public officials in technical service, are having a hard time breaking their limits. In consequence, to solve these problems it will be done with people who have qualifications of stage art professional in the center. Productions raise a support system of the city and venues subject to theatre arts professionals as a way of solving these problems. These are the efficient ways to develop performance cultures of issues presented and the Busan area performing arts Activation Plan is proposed.

This study aimed to examine whether needs for scaling are associated with health behaviors in a representative sample of middle-aged Korean people. We examined 5120 individuals aged 40 to 64 years who participated in the Seventh Korea National Health and Nutrition Examination Survey. Multivariate logistic regression analysis was performed with adjustments for demographic variables and health status. This analysis revealed significant associations between needs for scaling and the following: current smoking, no visits to dental clinics, current drinking, non-oral checkups, and non-use of oral care products. As a result of a subgroup analysis, significant factors differed according to gender. As a result of this study, needs for scaling were associated with identified health behaviors and findings about health behaviors that are effective for maintaining and promoting periodontal health in middle-aged people were confirmed.

Although coal-fired power generation has played a role as base load unit, it has incurred various social costs in the process of generating and providing electricity. It is necessary to extend the proportion of low-carbon power generations, and reduce the ratio of coal-fired power generation to cope with global climate changes. This study, therefore, attempts to estimate the public's willingness-to-pay (WTP) for substitution of supplied electricity from hydro-electricity generation, a representative renewable energy, for coal-fired power generation. To this end, we apply the contingent valuation (CV) method, widely used technique when valuing non-market goods, to elicit the public's WTP. In addition, a spike model is employed to consider zero WTPs. After the empirical analysis with 1,000 households CV survey data, the results show that mean household's WTP for replacing supplied electricity from hydro-electricity generation with coal-fired power generation is estimated to be about 54 KRW per kWh. The results of this study are expected to contribute to determining energy-mix and provide benefit information of hydro-electricity generation.

The aim of this study was to evaluate the correlation between senile eye diseases such as age-related macular degeneration (AMD), glaucoma and oral health behaviors. Data from the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-2) were used to analyze oral health behaviors according to the presence of AMD and glaucoma. Demographics and oral behaviors were analyzed using the complex chi-square test and complex logistic regression to compare participants with AMD and glaucoma with those without AMD and glaucoma. According to the presence or absence of AMD and glaucoma, there were statistically significant differences in age, education level, oral care product use, and difficulty in speaking variables. The results of this study provide evidence of a significant association in some variables between oral behaviors and senile eye diseases.

With the recent rapid development of deep learning technology, the demand for analyzing huge text documents in the national R&D field from various perspectives is rapidly increasing. In particular, interest in the application of a BERT(Bidirectional Encoder Representations from Transformers) language model that has pre-trained a large corpus is growing. However, the terminology used frequently in highly specialized fields such as national R&D are often not sufficiently learned in basic BERT. This is pointed out as a limitation of understanding documents in specialized fields through BERT. Therefore, this study proposes a method to build an R&D KoBERT language model that transfers national R&D field knowledge to basic BERT using further pre-training. In addition, in order to evaluate the performance of the proposed model, we performed classification analysis on about 116,000 R&D reports in the health care and information and communication fields. Experimental results showed that our proposed model showed higher performance in terms of accuracy compared to the pure KoBERT model.

Smartphone have become commonplace because they have the advantage of facilitating communication with others and making life easier. The smartphone's system log stores various data related to the user actions. Since 2015, Huawei has been growing rapidly, with its sales volume increasing and it was ranked second in the world in three years. The use of Huawei smartphones by many users means that Huawei smartphones are likely to be used to detect traces of criminal investigations, so we need to study system logs of Huawei smartphones. Therefore, in this paper, we analyze system log which is forensically meaningful for Huawei smartphone. We also propose how to use logs in forensic investigation.

A total of 5,597 Korean subjects aged 20-64 years were analyzed using the KNHANES 2013-2015. Among the subjects, 41.1% of males and 5.5% of females were smokers, and risk of developing metabolic syndrome in smokers was significantly increased in men with age, alcohol, physical activity, obesity, and sleep(aOR 1.785, 95% CI 1.004-3.174), whereas it was not significantly higher in women. As a result of analyzing the difference of average nutrient intake according to smoking and metabolic syndrome, the energy, retinol and vitamin C intake were significant when age and gender were corrected in the smoker and metabolic syndrome group. In this study, we found that smoking behavior and metabolic syndrome were related to nutrient intake which requires a national level of lifestyle intervention for the prevention and management of metabolic syndrome.

Traditionally, the definition of a republic in the constitutional sciences has remained passive, identifying whether or not a king exists. However, this is not an accurate understanding. Reinterpreting the meaning of the Republic at this point is expected to play a role in easing the side effects of neo-liberalism. It is more important than anything to establish a concrete picture of what a republic is in reinterpretating its meaning. Therefore, the main content of this paper is to clarify it by presenting requirements for the Republic.

The objective of this study was to assess the association of changes in behaviors and depressed mood during the COVID-19 pandemic in Korea. A cross-sectional internet-based survey was conducted, using proportional samples of Korean adults and a logistic regression model was used to assess the association. As a result, negative changes of daily sitting or lying down time, daily walking time, smoking, and alcohol consumption were associated with being more depressed during the COVID-19 pandemic [odds ratios (ORs): 2.23 (95% CI=1.77-2.81), 2.04 (95% CI=1.63-2.56), 2.84 (95% CI=1.51-5.36), and 1.82 (95% CI=1.26-2.63), respectively]. This indicates that strategies to promote positive health behaviors change (increased activities and decreased consumption of smoking and alcohol) could help address psychological distress during the COVID-19 pandemic.

The purpose of this study is to identify the factors influencing the depression in workers with diabetes mellitus. Using data from the Korean National Health and Nutrition Examination Survey (KNHANES). 685 workers with diabetes mellitus who were ≥30 years of age were enrolled. Depression was evaluated on the basis of PHQ-9 levels. Data were analyzed by complex sample linear regression using SPSS/WIN 23.0. The factors influencing depression included gender, age, household type, household income level, education level, type of employment (p>.05). The additional factors included stress perception level, weekly walking days (p>.05). Therefore, it is necessary to prepare systematic programs for depression and a support system for health promotion plan for diabetes mellitus in work places and throughout society. In addition, research on depression management program development is needed.
