In modern society, we are living indoor at 80 - 90 % or more of the day, therefore most people are exposed to unconscious indoor air pollutants by various causes. When mother and infant, whose level of immunity are weak, are exposed to polluted indoor air, respiratory diseases and atopy can occur by the growth of bacteria. Therefore, appropriate indoor air quality management is important especially at nursery, elementary school and postpartum clinic etc. In this study, we compared the characteristics of the indoor air qualities of primary school facilities and infant facilities. In this study, seasonal effects were investigated. Also the effects of individual activity area were studied for indoor air quality. During summer season(May-August), the air qualities of each 16 elementary school and nursery school were investigated. During winter season(October-december), the air qualities of each 10 elementary school and nursery school were investigated. As a result, during winter season in 10 of 16 nursery school, $CO_2$ concentration exceeded regulation level of 1000 ppm. This resulted from the operation of heating system and poor ventilation. Also the air quality of all parameters during winter season were worse than during summer, maybe due to poor ventilation. Except HCHO, the concentrations of other parameters were higher in nursery school. This seems to result from relatively low individual activity area of nursery school than elementary school. From this research, more strong regulation for ventilation and installation of air purifier should be implemented.

Purpose: The purpose of this study was to examine the relationship between sleep quality and mental health among adolescents and identify the factors relating to mental health. Methods: The subjects consisted of 285 middle school students. The data were collected from May $2^{nd}$ to $27^{th}$, 2016. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficient and multiple linear regression with SPSS ver. 21. Results: The mean score for quality of sleep in adolescents was $4.20{\pm}2.64$, and the mean score for mental health was $13.67{\pm}12.93$. Poor sleepers showed higher scores for mental health than good sleepers. Mental health was found to have a positive correlation with both stress and quality of sleep. Stress and sleep quality were found to be significant factors influencing mental health and explained 59% of the variance in mental health. Conclusion: These findings indicate that effective intervention programs enhancing sleep quality should be provided for adolescents in order to prevent poor mental health.

This paper explores the possibility of segmentation of consumers based on their quality expectations toward the automotive telematics service. Hypotheses on utilizing consumers' expectations toward the automotive telematics service for the market segmentation and linking the segments with optimal product designs are formulated. Samples are segmented based on their perceived service quality to the service attributes from various configurations of automotive telematics service. Then, a regression analysis on the segmented groups of users is performed to check whether they have qualitatively differing evaluation on the service quality. The result indicates that the proposed segmentation is operational and differing product attributes configuration is desirable according to the characteristics of the consumer segment. Hence, according to the characteristics of each consumer segment formed based on their expectation toward the telematics service, a product differentiation strategy of the automotive telematics system can be designed and be proposed to the product line designer.

Many organizations have developed their own traditional quality information systems. But, they think of it as one of the functional information systems not as a company-wide decision support information systems. A study on traditional quality information systems(QIS) has been conducted and a new conceptual framework of quality information system is proposed in this paper. In order to support enterprise wide total quality management aggressively, a new conceptual framework, named quality management support information system(QMSIS) is developed and proposed. This framework is based upon Malcolm Baldrige National Quality Award(MBNQA) model integrates management information system approach and traditional quality information system concept. In this model, organizational performance and process performance can be monitored to support managers , decision making about organizational quality management activities.

Objectives: The purpose of the study is to investigate the influence of self-control on stress management and oral health related quality of life in high school students. Methods: A self-reported questionnaire was completed by 422 high school students in Ulsan from December 1, 2014 to February 20, 2015. The study instrument consisted of stress and self-control. The stress instrument included 17 items modified by Kim and Lee. The self-control instrument was modified by Kim and had 20 items. Pearson's correlation analysis was conducted to analyze the relationship between stress, self-control and oral health related quality of life. Regression analysis was used to analyze the effect of the stress on oral heal related quality of life. Hierarchical regression analysis was done to analyze the control effect of self-control in the relationship between the stress and oral health related quality of life. Results: The higher stress level resulted in the lower oral heal related quality of life. The higher self-control maintained the higher oral health related quality of life. The higher long term pursuit of satisfaction led to higher oral health related quality of life. The immediate suppression of satisfaction had a positive influence on the higher oral health related quality of life. Conclusions: There were significant correlations in self-control on stress management and oral health related quality of life.

Purpose: This study aimed to construct and test a hypothetical model of the quality of life of school-age children with asthma based on the health-related quality of life model by Wilson and Cleary. Methods: Data were collected from 205 pairs of pediatric outpatients diagnosed with asthma and their parents in Seoul and Gyeonggi-do from July 2016 to April 2017. The exogenous variables were asthma knowledge, number of accompanying allergic diseases, and social support. The endogenous variables were asthma self-efficacy, asthma symptom control, perceived health status, parental quality of life, and children's quality of life. For data analysis, descriptive statistics, factor analysis, and structural equation modeling were performed. Results: Eighteen of the twenty-four hypotheses selected for the hypothetical model were attentive and supported statistically. Quality of life was explained by asthma self-efficacy, asthma symptom control, perceived health, parental quality of life, and asthma knowledge with 83.5%. Conclusion: Strategies for promoting self-efficacy and enforcing asthma knowledge will be helpful for the improvement of health-related quality of life with school-aged asthmatic children.

This study investigates the impacts of carbon neutrality and air quality control policies on near-term climate change in East Asia, by examining three Shared Socioeconomic Pathways (SSPs) scenarios from five climate models. Specifically, low carbon and strong air quality control scenario (SSP1-1.9), high carbon and weak air quality control scenario (SSP3-7.0), and high carbon and strong air quality control scenario (SSP3-7.0-lowNTCF) are compared. For these scenarios, the near-term climate (2045-2054 average) changes are evaluated for surface air temperature (SAT), hot temperature extreme intensity (TXx), and hot temperature extreme frequency (TX90p). In all three scenarios, SAT, TXx, and TX90p are projected to increase in East Asia, while carbon neutrality reduces the increasing rate of SAT and hot temperature extremes. Air quality control strengthens the warming rate. These opposed mitigation effects are robustly forced in all model simulations. Nonetheless, the impact of carbon neutrality overcomes the impact of air quality control. These results suggest that fast carbon neutrality, more effective than an air quality control policy, is necessary to slowdown future warming trend in East Asia.

최근 자기주도적 학습, 평생교육이 강조되면서 교육과정에서 학교도서관의 중요성이 부각됨에 따라 학교도서관의 구조적, 제도적, 운영적 관점에서의 연구들이 주로 이루어지고 있다. 그러나 학교도서관이 자율성 기반의 자기주도적 교육 운영에 핵심적인 역할을 수행한다는 점을 고려하면 학교도서관 이용자의 자율적 내적동기와 같은 미시적인 주제에 대한 고찰이 필요하다. 이에 본 연구는 자기결정성 이론을 기반으로 학교도서관 이용 동기에는 어떠한 유형이 더 중요한지, 학교도서관 이용 동기가 서비스 품질에 미치는 영향은 어떠한지에 대해 고찰하였다. 또한 학교도서관 이용 동기와 서비스 품질 인식이 도서관 이용자의 학년에 따라 어떻게 달라지는가에 대해서도 알아보았다. 포커스 그룹 인터뷰를 통한 예비 연구를 기반으로 서울에 소재한 4개의 고등학교와 2개의 중학교 학생 588명을 대상으로 학교도서관 이용 동기가 도서관 서비스 품질 인식에 미치는 영향에 대해 설문조사를 실시하였다. 서비스 품질, 그리고 서비스 품질 요소 중 서비스 감성, 정보제어, 도서관 장소를 종속 변수로 각각 설정하였을 때, 네 가지 경우 모두 내재적 동기요인이 외재적 동기요인보다 더 많은 영향을 미치는 것으로 분석되었다. 또한 중학생과 고등학생 집단을 각각 별도의 대상으로 설정하였을 때에도 두 집단 모두 내재적 동기가 높을수록 서비스 품질을 더 높게 인식하는 것으로 나타났다. 본 연구는 자기결정성 이론을 학교도서관 서비스에 적용하였다는 점, 이론을 토대로 구분한 동기 유형의 영향력을 측정하였다는 점, 그리고 학교도서관 서비스 향상을 위해 미시적 요인에 초점을 맞추었다는 점에서 의의를 가진다.
