Objectives The aim of this study is to evaluate radiation exposure resulting from the comprehensive health examinations of selected university hospital programs and to present basic data for research and management strategies on the health effects of medical radiation exposure. Methods Radiation-based diagnostic studies of the comprehensive health examination programs of ten university hospitals in Seoul, Korea, as introduced in their websites, were analyzed. The medical radiation studies of the programs were reviewed by radiologists. Only the effective doses of the basic studies were included in the analysis. The optional studies of the programs were excluded. Results Among the 190 comprehensive health examination programs, 132 programs (69.5%) included computed tomography studies, with an average of 1.4 scans. The average effective dose of radiation by program was 3.62 mSv for an intensive program for specific diseases; 11.12 mSv for an intensive program for cancer; 18.14 mSv for a premium program; and 24.08 mSv for an overnight program. A higher cost of a programs was linked to a higher effective dose (r=0.812). The effective doses of the examination programs for the same purposes differed by as much as 2.1 times by hospital. Inclusion of positron emission tomography-computed tomography was the most critical factor in determining the level of effective dose. Conclusions It was found that radiation exposure dose from comprehensive health exam programs targeted for an asymptomatic, healthy public reached between 3.6 and 24 times the annual dose limit for the general public. Relevant management policies at the national level should be provided to minimize medical radiation exposure.

Characteristics and advantages of the thermal desorption-comprehensive two dimensional gas chromatography-time of flight mass spectrometry (TD-GCxGC-TOFMS) were discussed and the organic compound's analysis result was shown for the ambient $PM_{2.5}$ sample collected in Seoul, Korea. Over 10,000 individual organic compounds were separated from about $70{\mu}g$ of aerosols in a single procedure with no sample pre-treatment. Among them, around 300 compounds were identified and classified based on the mass fragmentation patterns and GCxGC retention times. Several aliphatic compounds groups such as alkanes, alkenes, cycloalkanes, alkanoic acids, and alkan-2-ones were identified as well as 72 PAH compounds including alkyl substituted compounds and 8 hopanes. In Seoul aerosol, numerous oxidized aromatic compounds including major components of secondary organic aerosols were observed. The inventory of organic compounds in $PM_{2.5}$ of Seoul, Korea suggested that organic aerosol were constituted by the compounds of primary source emission as well as the formation of secondary organic aerosols.

본 연구는 미국 텍사스 주 오스틴 시의 환경정책 형성과정에 대한 역사적 고찰을 통해, 환경운동과 환경정책과의 관계를 파악하고 그 역사적 경험에 대한 이해를 목적으로 한다. 특히 가장 최근의 도시 환경정책으로서 "스마트 성장 정책(Smart Growth Initiative)"에 대한 정책분석을 시도한다. 오스틴은 과거 35년 동안 급속한 인구와 경제발전을 경험하였고, 이러한 과도한 발전에 대한 경험은 오스틴 시민들에게 환경적 인식을 키우는 계기가 되었다. 오스틴 시 정부는 "도시기본계획(Comprehensive Plans)", "분수계 보호 조례(Watershed Protection Ordinance)", 그리고 가장 최근의 "스마트 성장정책(Smart Growth Initiative)"에 이르기까지 다양한 환경정책 등을 통해 이러한 환경적 문제들에 대처하려고 노력하여 왔다. 본 연구의 결론은 다음과 같다. "환경적 이슈 등이 최근 30년간 오스틴 시의 정책적 우선순위가 되어 왔음에도 불구하고 환경정책 노력들이 시의 제도적인 부분으로 완전히 흡수되는 데에는 실패했다" 이러한 결론은 환경운동과 환경정치적 행위자들의 노력이 환경정책 형성에 있어 중요한 동기를 제공함에도 불구하고 진보적인 도시 환경체제(Progressive Environmental Regime)를 유지하는 데에는 충분하지 않음을 보여준다.

Purpose: This study was conducted to evaluate effects of a comprehensive lifestyle improvement program for middle-aged women with cardio-cerebrovascular disease (CVD)-related risk factors. Methods: The research adopted a non-equivalent control group pretest-posttest design. The number of participants was 18 in the experimental group and 16 in the control group sampled among middle-aged women who had CVD-related risk factors residing in a community. The experimental group participated in a four-session comprehensive lifestyle promotion program, which consisted of lectures, demonstrations, small-group meetings and telephone-counseling. The effects of the program were evaluated by measuring knowledge, attitude, health behavior, and self-efficacy for CVD prevention. Results: The experimental group showed a significant increase in self-efficacy for CVD prevention compared to the control group. There was no significant increase in knowledge, attitude, and health behavior. Conclusion: The results suggest that the comprehensive lifestyle improvement program was effective in improving self-efficacy for CVD prevention. There is a need to develop more effective lifestyle improvement programs designed to improve knowledge, attitude, and health behavior for CVD prevention. In further research, a follow-up evaluation is also needed to investigate any delayed effects on targeted variables among which no significant differences emerged immediately after the completion of the program.

On September 26, 2017, South Korean government has established the Particulate Matter Comprehensive Plan to improve Korean air quality by 2022, which aims to reduce annual mean surface $PM_{2.5}$ concentration to $18{\mu}g/m^3$. This study demonstrates quantitative assessment of predicted $PM_{2.5}$ concentrations over 17 South Korean regions with the enforcement of the comprehensive plan. We utilize the Community Multi-scale Air Quality (CMAQ) modeling system with CAPSS 2013 and CREATE 2015 emissions inventories. Simulations are conducted for 2015 with the base emissions and the planned emissions, and impacts from model biases are minimized using the RRF (Relative Response Factor). With effective emission reduction scenario suggested by the comprehensive plan, the model demonstrates that the surface $PM_{2.5}$ concentration may decrease by $6{\mu}g/m^3$ ($23{\mu}g/m^3{\rightarrow}17{\mu}g/m^3$) and $7{\mu}g/m^3$ ($25{\mu}g/m^3{\rightarrow}18{\mu}g/m^3$) for Seoul and South Korea, respectively. The number of high $PM_{2.5}$ days(daily mean>$25{\mu}g/m^3$) also decreases from 21 days to 4 days.

Malignant gliomas are the most common type of primary brain tumor and are in great need of novel therapeutic approaches. Advances in treatment have been very modest, significant improvement in survival has been lacking for many decades, and prognosis remains dismal. Despite "gross total" surgical resections and currently available radio-chemotherapy, malignant gliomas inevitably recur due to reservoirs of notoriously invasive tumor cells that infiltrate adjacent and non-adjacent areas of normal brain parenchyma. In principle, the immune system is uniquely qualified to recognize and target these infiltrative pockets of tumors cells, which have generally eluded conventional treatment approaches, In the span of the last 10 years, our understanding of the cancer-immune system relationship has increased exponentially; and yet we are only beginning to tease apart the intricacies of the central nervous system and immune cell interactions. This article reviews the complex associations of the immune system with brain tumors. We provide an overview of currently available treatment options for malignant gliomas, existing gaps in our knowledge of brain tumor immunology, and strategies that might be exploited for improved design of "custom immunotherapeutics." We will also examine major new immunotherapy approaches that are being actively investigated to treat patients with malignant glioma, and identify some current and future research priorities in this area.

The purpose of this study was to identify the health promotion behavior and its related factors of persons who wanted a comprehensive health check-up in order to provide a basis for health education to promote health enhancing behavior. Study variables were induced from Pender's Health Promotion Model. The subjects were 160 persons who had a check-up at the health promotion center in a university hospital in Tae-Gu, between September 8 and 22, 1998. The following instruments were used in the study : Lee Tae Wha's Health Promoting Life-style Profile, Park Chai soon's Self-efficacy Instrument and Moon Jeong Soon's Perceived Benefit and Barrier Instrument. Data was collected by self-reporting questionnaire. Analysis of the data was done by SAS program, t-test, ANOVA and Pearson-Correlation Coefficient. The results of this study were as follows. 1. The average score for the health-promotion behavior was 104.64. In the subcategories, self-actualization showed the highest degree of performance and physical exercise showed the lowest degree of performance. 2. In the relation of general characteristics of subjects to the level of health-promoting behavior, the male, the married, the group with several symptoms showed a high level of health-promoting behavior. 3. The relationship between the degree of performance in health-promotion behavior and its correlates were as follows: Self-efficacy was positively correlated to health promotion behavior, while the perceived barrier was correlated negatively. But the perceived benefit did not show a significant correlation with health promotion behavior. Results suggest that the development of programs with strategies to strengthen doing physical exercise and concerning health, increase self-efficacy and exclude the barriers to health promotion is recommended to individuals seeking a comprehensive health check-up.
