This study was conducted to identify the subjective damage caused by COVID-19 and its related factors. The study subjects were members of the Korean Dental Association (KDA). We investigated the damage to dental clinics and hospitals caused by COVID-19 between January and April 2020. After analyzing the final 3,189 responses, the rate of decrease in patients was the highest at 34.9% in March, and the rate of decrease in income was the highest at 34.0% in April. As a result of the multilevel analysis, the damage caused by COVID-19 was greater in regions with more confirmed patients, more careers, and fewer dental staff. The government should establish a compensation plan for hospitals and clinics to prevent the collapse of the medical system due to the prolonged COVID-19. In addition, support for dentistry should be provided to maintain the oral health care system in the future.

Objectives: The aim of the present study is to elucidate the relationship of community capacity to health in a metropolitan area in Korea. To do so, a multi-level model to verify the contextual effects of community capacity is presented. Methods: The study materials are the "The 4th Seoul Citizens Health Indicators Surveys" on 404 dong in Seoul. The community capacity indicators were developed in two strata: individual-level indicators with community identity domain; and community-level indicators with participation in community organizations, number of non-profit organizations, degree of organizing of community-based organizations, and volunteer activities. Results: Higher unhealthy probability occurs among those with lower community capacity at the community level, lower individual income, and lower community satisfaction at the individual level. It contributed to explaining self-rated health status and showed that there were contextual effects of the community going beyond the compositional effects of the individual. Conclusions: In the process of building community capacity, a community autonomously finds pending issues and solves related problems, and in so doing, raises the social quality and establishes the conditions for health promotion. Thus, the significance of neighborhood needs to be discovered and created in a new way through the development of community capacity.

The reliability analysis for nonnormal distributions using the three level DOE(design of experiments) method was developed by Seo and Kwak in 2002. Although this method estimates only up to the first four moments(mean, standard deviation, skewness, and kurtosis) of the system response function, the result and the type of probability distribution determined by using the Pearson system are shown very good. However the accuracy is low in case of nonlinear performance function and sometimes, the level calculated is outside of the region in which the random variable is defined. In this article we suggest a modified three level DOE method to overcome these weaknesses and to obtain optimum choice for 3 levels and weights to handle nonnormal distributions. Furthermore we extend it to finding the optimum choice for 5 levels and weights to increase the accuracy in case of nonlinear performance function. A systematic procedure for reliability analysis is then proposed by using the Pearson system.

Purpose: This study was conducted to examine the individual and community level factors associated with physical activity and to identify its relative effects using a multilevel analysis among Korean adults in certain counties. Methods: A cross-sectional data of 39,547 adults (age range of 19~64 years) living in 82 counties from the 2013 Korean Community Health Survey (KCHS) was analyzed. Individual and social correlates from KCHS and physical environmental data from the Korean Statistical Information Service were collected. A multilevel logistic regression was performed using Stata 10.0 IC. Results: Multilevel analyses showed that the effect of social and physical environmental on engaging in moderate or vigorous physical activity (MVPA) was significant in comparison to the influence of individual correlates. The individual factors that were associated with participating in MVPA included gender, marital status, education, job, and household income. In the community level, social environmental factors associated with engagement in MVPA were higher satisfaction with healthcare service (OR=3.410, 95% CI=1.109~11.269), a high level of social support (OR=5.920, 95% CI=1.459~22.657) and social network (OR=1.025, 95% CI= 1.017~1.032). Conclusion: To promote moderate or vigorous physical activity in Korean adults in some counties, social environmental factors should be considered along with individual correlates.

The purpose of this study was to compare the risk-adjusted in-hospital mortality for craniotomies between logistic regression and multilevel analysis. By using patient sample data from the Health Insurance Review & Assessment Service, in-patients with a craniotomy were selected as the survey target. The sample data were collected from a total number of 2,335 patients from 90 hospitals. The sample data were analyzed with SAS 9.3. From the results of the existing logistic regression analysis and multilevel analysis, the values from the multilevel analysis represented a better model than that of logistic regression. The intra-class correlation (ICC) was 18.0%. It was found that risk-adjusted in-hospital mortality for craniotomies may vary in every hospital. The agreement by kappa coefficient between the two methods was good for the risk-adjusted in-hospital mortality for craniotomies, but the factors influencing the outcome for that were different.

Purpose: This study was carried out to investigate the effects of improvement in self-rated health, self-efficacy, perceived benefit and health promotion behavior by running a health promotion program through the coalition of industries, universities and districts. Methods: This study was designed as non-equivalent control group research. Data were collected from 62 participants in a health promotion program who were enrolled in a community center (experimental group: 29, control group: 33). The program was applied from October to November, 2008. The health promotion program was composed of value, competence, action, and policy based on a multi-level health promotion model. Collected data were analyzed through $x^2$ test, t-test, and Wilcoxon test. Results: After participating in the health promotion program, the experiment group showed statistically significant increases in self-efficacy, perceived benefit and health promotion behavior but not in self-rated health. Conclusion: It was proven that the health promotion program enhanced the health promotion level in the community.

Multi-level (macro-level, meso-level, and micro-level) mechanism of prefinitely strained concrete materials os studied The multi-level analysis explains the additional quasibrittle concrete material ductility that comes from lateral confinement and their multi-level interaction mechanisms. The so-called "upgraded tube-squash test" is used to achieve 50% axial strain and over 70 degree of deviatoric strain of quasibrittle concrete materials under extremely high pressure without producing visible cracks. In the micro-level analysis, the variations of hydration rte, micropores, and hydrate phased are analyzed. In the meso-level analysis, mesocracks (the initial invisible cracks) at the interfaces between aggregates and cement paste matrices are studied. The high confining effect in the specimen on the meso-level cracks is also studied. In the macro-level analysis, the physical behavior of prefinitely strained concrete materials is studied. The co-relationships of the results from the three distinct levels of analyses based in various prestraining (0%, 15%, 35%, and 50%) are studied. For the extremely deformed or strained concrete problems, multi-level analysis will be used to explain the unclear and unstudied mechanism of concrete materials, The multi-level analysis can provide us with valuable insights that can explain the additional ductility and confining effect in concrete. concrete.
