  • While increased use of energy and fossil fuel in the recent years could worsen air quality and climate change, only few studies have been conducted on estimation of greenhouse gas emissions and characterization of emission types by sectors and regions in Korea. In this study, greenhouse gases emissions based on resions(Si, Gun, Gu) and emitted sectors(industry, transport, cemmercial and institutional, residential, waste, agriculture, others) were investigated using GHG-CAPSS(Greenhouse GasClean Air Policy Support System) developed to support to national and regional greenhouse gases reduction strategies. GHG-CAPSS follows IPCC(Intergovernmental Panel on Climate Change) Guideline methodology to categorize the emission sources and estimation of greenhouse gases using bottom-up approach. Estimated total greenhouse gases emissions were 588,011 thousand tons as $CO_2$ equivalent. Industry(50.1%) sector exhibited the highest portion followed by transport(17.6%), commercial and institutional(12.6%), residential(12.6%), waste(2.6%), agriculture(2.5%). Based on regional estimation, Gyeonggi(14.9%) demonstrated the highest emitted greenhouse gases among big cities followed by Jeonnam(12.4%), Gyeongbuk(11.0%), Ulsan(9.2%) and Seoul(8.9%).

  • Climate change lead to environmental pollution caused by the radical economic growth and development of industry. The amount of damage from abnormal climate is increasing rapidly for this reason in Korea. In particular, the cities is a lot of carbon emission quantity from the radical growth. Thus the government present "low carbon green growth" for eco-friendly city planning. As one of the important factors effecting climate change, active researches on land use change is performed. In this study, we knew land use change of each scenarios using land use equilibrium model which is kind of predictive model of land use in Japan. First, we selected study area to Jeju lsland. For this study, indicators for input data were selected and spatial data for input data were established using GIS program. Second, we established future scenarios based in 2040s. There are 2 future scenarios: dispersion scenario, compact scenario. Third, we compared with residential area of current and residential area for future scenarios. Results showed that residential area of the difference between current and dispersion scenario were 1,230 ha and residential area of the difference between current and compact scenario were 1,515 ha. Finally, for comparing carbon dioxide absorption volume between dispersion scenarios and compact scenarios, we calculated carbon dioxide absorption volume according to residential area decreased of each future scenarios. Results showed that carbon dioxide absorption volume in dispersion scenario was 477,878 ton and carbon dioxide absorption volume in compact scenario was 588,606 ton. Therefore, the study showed that land use equilibrium model is expected to put to use for future enhancement in creating data for climate change stabilization. And it is also expected to be utilized for city planning research in Korea.

  • Heat wave is a disaster, which increases morbidity and mortality in temperate regions. Climate model results indicate that both intensity and frequency of heat wave in the future will be increased. This study shows the result about relationship between excess mortality and offensive airmass in 7 metropolitan cities, and an operational Heat-Health Warning System (HHWS) in Korea. Using meteorological observations, the Spatial Synoptic Classification (SSC) has been used to classify each summer day from 1982 to 2007 into specific airmass categories for each city. Through the comparative study analysis of the daily airmass type and the corresponding daily mortality rate, Dry Tropical (DT), and Moist Tropical plus (MT+) were identified as the most offensive airmasses with the highest rates of mortality. Therefore, using the multiple linear regression, forecast algorithm was produced to predict the number of the excess deaths that will occur with each occurrence of the DT and MT+ days. Moreover, each excess death forecast algorithm was implemented for the system warning criteria based on the regional acclimatization differences. HHWS will give warnings to the city's residents under offensive weather situations which can lead to deterioration in public health, under the climate change.

  • Objective: The purpose of this study is to investigate the effects of childcare teachers' teacher efficacy, psychological burnout and the practice of respecting rights for infants. Methods: For this study, questionnaires were distributed to 398 childcare teachers in the cities of I and S. The collected data were analyzed by descriptive statistic, multiple regression and Cronbach's ${\alpha}$ for reliability by SPSS-WIN computer program. Results: The results yielded some interesting results. First, childcare teachers were shown to have higher respecting rights for infants but just average teacher efficacy rates. Secondly, the study showed a positive correlation between the practice of respecting rights for infants and childcare teachers' teacher efficacy. However, there was a negative correlation between the practice of respecting rights for infants and psychological burnout. There was also a negative correlation between the practice of respecting rights for infants and childcare teachers' teacher efficacy. Third, the higher the childcare teachers' teacher efficacy of childcare teachers, the more positive influences existed in the practice of respecting rights for infants. It also showed that the lower the degree of psychological burnout, there was a negative impact on the practice of respecting rights for infants. Conclusion/Implications: The results of this study suggest that a support plan is needed to boost childcare teachers' teacher efficacy, and to lower the psychological burnout of childcare teachers with regards to the practice of respecting rights for infants.

  • Objectives: The aim of this study is to analyze the differences in factors related to the incidence of dental caries between children in fluoridated and non-fluoridated areas and compared the DMFT and DMFS scores to confirm the effect of water fluoridation program (WFP) in Geoje and Changwon. Methods: The oral health examination and questionnaire survey were conducted in fluoridated and non-fluoridated areas. The number of surveyed children aged 8, 10, and 12 years in the fluoridated and non-fluoridated area of two cities was 1,524 and 1,383, respectively. Self-recorded questionnaires included self-perception of their own dental health, daily toothbrushing frequency, intake frequency of cariogenic sweet snacks and beverages, experience of gingival bleeding, experience of unmet dental treatment, and use of oral hygiene device except for toothbrush and toothpaste. The prevalence of caries and fissure-sealant status were surveyed. The logistic regression analysis was used to analyze the difference in children's self-rated oral health status between the fluoridated and non-fluoridated area. The mean number of sealed teeth and surfaces, marginal means of the DMFT and DMFS scores adjusted for the difference in the samples' sex distribution, and region were compared between the fluoridated and non-fluoridated areas. Results: In the fluoridated area, the experience rate of unmet dental treatments was higher among children aged 10 years, intake frequency of cariogenic sweet snacks and beverages were higher among the whole sample, and experience rate of professional fluoride application were lower than in the non-fluoridated area. The DMFT score for permanent dentition adjusted for differences in sex, region, and mean number of fissure-sealed teeth in the fluoridated area was significantly lower among whole samples and 8-, 10-, and 12-year-olds alone than in the non-fluoridated area. Conclusions: WFP can alleviate oral health inequality because it is effective in reducing the incidence of caries among children is disadvantaged demographic, socioeconomic, and cultural contexts.

  • The purpose of this study was to identify vulnerable area of emergency medical care. In the existing method, the emergency medical vulnerable area is set as an area that can not reach the emergency room within 30 minutes. In this study, we set up an area that can not reach within 30 minutes including the accessibility of 119 emergency center. To accomplish this, we obtained information on emergency room and 119 emergency center through Open API and constructed road network using digital map to perform accessibility analysis. As a result, 509 emergency room are located nationwide, 78.0% of them are concentrated in the region, 1,820 emergency center are located, and 61.0% of them are located in rural areas. The average access time from the center of the village to the emergency room was analyzed as 15.3 minutes, and the average access time considering the 119 emergency center was 21.8 minutes, 6.5 minutes more. As a result of considering the accessibility of 119 emergency center, vulnerable areas increased by 2.5 times, vulnerable population increased by 2.0 times, and calculating emergency medical care vulnerable areas, which account for more than 30% of the urban unit population, it was analyzed that it increased from 17 to 34 cities As a further study, it will be necessary to continuously monitor and research the real-time traffic information, medical personnel, medical field, and ambulance information to reflect the reality and to diagnose emergency medical care in the future.

  • The purpose of this study was to investigate the relationships between behavioral inhibition, ambivalence over emotional expressiveness and social anxiety among Korean middle school students. In addition, we examined whether ambivalence over emotional expressiveness mediated the relationship between behavioral inhibition and social anxiety. For this aim, we conducted a survey of 357 first-third grade students from 6 middle schools located in the cities of Wonju, Seoul, Suwon, Suncheon, and Kwangju. Survey data was analyzed through descriptive statistics, correlation analysis, multiple regression analysis, and Sobel test using the SPSS/WIN 19.0 program. Results were as follows: First, there was a positive correlation between behavioral inhibition and social anxiety on ambivalence over emotional expressiveness. Second, ambivalence over emotional expressiveness was found to partially mediate the relationships between behavioral inhibition and interpersonal anxiety as well as performance anxiety. In other words, while behavioral inhibition tends to affect interpersonal anxiety and performance anxiety in a very direct way, it also influences them indirectly by increasing the ambivalence over emotional expressiveness. These results suggest that counseling of middle school students with social anxiety due to innate behavioral inhibition should seek to reduce their social anxiety by decreasing their ambivalence over emotional expressiveness.

  • This study constructed a structural model and examined the fit and significance of the model to identify the influencing factors on the organizational commitment of ROTC cadets. The subjects of this study were 209 male students in grades 3 and 4 ROTC cadets of eight universities located in D, P, and G cities. Data were collected from April 13 to May 29, 2018. The data collected were analyzed by SPSS / WIN 20.0 and AMOS 21.0 programs. A positive correlation was observed between the ROTC instructor's leadership, self-efficacy, job satisfaction, and organizational commitment. Six of the six pathways of the hypothetical structural model were statistically significant. The hypothetical model showed a good fit for the data. The model fit indices were ${\chi}^2/df=1.51$, GFI=.98, AGFI=.90, NFI=0.98, NFI=.97, RMR=.02, RMSEA=.05, and TLI=.98. The ROTC Instructor's leadership and self-efficacy had direct and indirect effects on the organizational commitment. Job satisfaction had the strongest direct influence on organizational commitment. This model explained 73% of the variance in organizational commitment. Therefore, it is necessary to develop an effective education and intervention program that can enhance the ROTC instructor's leadership, self-efficacy, and job satisfaction to increase the organizational commitment of the ROTC cadets.

  • The purposes of this study was to confirm the current issues of workforce policy of dental auxiliary personnel in Korea. The literature review and data collection were conducted in terms of the auxiliary personnel supply, regional distribution, legal works, working environment. Despite the rapid increase in the number of dental hygienists, the number of active dental hygienists is less than half of the total, and the dental clinics still experience the shortage. Considering the dental hygienist's work, the available dental auxiliary personnel for the dental assistance is limited. The proportion of dental hygienists is concentrated in large cities, and the ratio of dental clinics composed of only dental hygienists is high. Thus, it is essential to look for a plan to solve the disparity. The criterion for judging the legality of the works is ambiguous because a large portion of dental hygienist's work is not specified in the Medical Technicians Act. The job life is also shortened, and occupational profession and satisfaction are lowered. Thus, job burnout is accelerating. The difference between the legal works and the practiced works of dental hygienist and the conflict between the personnel might be due to the lack of utilization plans for the dental personnel at the government level. Therefore, the government should establish the roles of dental hygienist in accordance with the demands of the dental health service, institutionalize the necessary policies accordingly, and make efforts to establish plans to improve the relevant laws and utilize the manpower appropriately.
