Objectives : To identify the factors related to awareness, treatment, and control of hypertension in a Gwacheen population. Methods : This study surveyed 1,176 Gwacheon residents older than 40 years, and measured blood pressure using a standardized guideline in 1999. The study subjects were 473 adults (175 males, 295 females) with hypertension defined as a systolic blood pressure $\geq$140 mmHg, diastolic blood pressure $\geq$90 mmHg or reported treatment with antihypertensive medication. Information on awareness, treatment, and control of hypertension, and sociodemographic and health-related factors .was collected through person-to-person interviews with a structured questionnaire. Results : Overall, 252 (53.3%) of hypertensive subjects were aware of their condition, of whom as many as 193 (76.6%) were being treated, and 81 (42.0%) had their blood pressure controlled at the recommended level (<140/90 mmHg). However, of the 473 subjects found to have hypertension, only 40.8% were being treated, and 17.1% were under control. There were no significant differences in the proportions of awareness, treatment, and control of hypertension. In multiple logistic regression models, awareness of hypertension was positively associated with age and family history of hypertension in females. Control of hypertension was also positively associated with haying a partner and marital status in females.. Conclusion : These findings demonstrate that much greater efforts on improving awareness, treatment, and control of hypertension are needed, even in urban community settings, considering related factors such as a9e, family history, and marital status. However, these factors should be further investigated for their causal relationship.

As of 2018, the proportion of permanent rental and national rental for low-income households accounted for 53% of the total rental housing inventory. Residents of small rental apartments can be categorized as energy poverty, mostly as elderly or handicapped people. They are lived in a low indoor temperature and high condensation possibility. However, there is no study on the indoor thermal environment of permanent rental apartment for low-income households. Especially, indoor temperature distribution and moisture generation and resulted condensation behaviors of aged permanent rental apartment is reported. The aims of this study is to investigate the actual condition of the condensation problem in old apartment buildings for low-income households by long-term measurement. The room temperature and humidity were measured by long-term measurements for the 17 households(7 households are newly constructed and 10 households are old building). Also, the airtightness and window insulation performance were measured. Finally, the generation of water vapor and the occurrence of condensation were analysed based on the measurement results. As a result, the level of water vapor generation for the aged permanent rental apartment showed a large variation according to the lifestyle of each household. Mostly the analyzed households showed significantly lower humidity level compared to the conventional level defined by the IEA Annex. The moisture generation rates of the analyzed low-income households were divided into three levels: 5.05kg/day(max.), 1.88kg/day(mean), 0.32kg/day(min.). The condensation occurrence frequency was 0.3~79% and showed a large deviation. The households with high condensation rates were old building.

Dental caries has been widely prevalent with presence of cavitation cm teeth. For the last several decades, the prevalence of dental caries in developed countries has rapidly decreased so there has been needed a new and detailed diagnostic guideline to differentiate the severity of dental caries, especially for early status of caries. The cariology specifically requires the development of an integrated definition of dental caries and uniform systems for measuring the caries process in the fields of clinical diagnosis and treatment, epidemiological researches, and dental education and so forth. The international Caries Detection and Assessment System (ICDAS) optically measures the enamel surface changes and potential histological depth of carious lesions by relying on surface characteristics of teeth. ICDAS is a visual classification system that was developed to diagnose the subtle changes of enamel surface, predict the progress direction of early caries, allow standardized data collection in relation to caries in different settings, and to enable better comparison of oral health between countries worldwide and research studies.

There has been much studies about the use of the ERVs(energy recovery ventilation system) in different climate zones. Also, lot of ERVs have been installed in multi-residential buildings in Korea to minimize the energy demand for ventilation. In these days, some manufactures of ERVs insist that ERVs should be used in winter for preventing condensation in residential building in Korea. The basic premise of their argument is that the humidity of outdoor air is always low than indoors in winter, and the operation of ERVs can be maintained indoor humidity in low. However, the results of our study showed the different results of their arguments. The indoor humidity was increased with the operation of the ERVs in winter season in Korea when the outdoor weather was snowing. Also in this study, we found the problem on humidity control not only for the high outdoor humidity but also indoor indoor humidity level due to excessive humidifying. In this paper, the control strategies of ERVs for preventing condensation in multi-residential buildings in cold and humid conditions will be addressed. The measurement results will be reported and discussed.

Ventilation is the most effective approach to providing acceptable indoor air quality and increasing the work performance. Under a specific circumstance, outdoor air is clean. However, if the outdoor PM concentration is high, indoor PM concentration can be increased with the operation of a ventilation system. Thus, additional control strategy of the ventilation system is necessary when outdoor PM concentration is high. In this paper, the control strategy to secure indoor air quality and energy saving in residential building ventilation is discussed. The ventilation system with an air filtering mode is suggested and the effects of the control strategy of air cleaning mode are analyzed by simulation on indoor air quality and energy efficiency. It is available to meet CO₂ concentration and PM concentration below the standard with the operation of the ventilation system applied suggested control strategy (Case 4). Also the heating energy consumption of Case 4 was reduced 49% compared to Case 1 which operates the ventilation system all time with a constant flow rate (0.5 ACH). Because the suggested control strategy (Case 4) operates at a lower ventilation fan flow rate when outdoor PM concentration is high, it can lead to lower operation frequency of the air-cleaning mode.

This study aimed to introduce what Korea national oral health surveys are and examine recent oral health status in Korean children. Korea Government has implemented national oral health-related surveys during the past two decades. The surveys with oral health examination are Korean Children’s National Oral Health Survey (KCNOHS) since 2000 in 5-year-old and 12-year-old children and Korea National Hhealth and Nutrition Examination Survey (KNHANES) since 2007 aged 1 year and more. KCNOHS provides the information about the distribution of prevalence of dental caries, gingival health , behavioral factors, and dental clinic demands etc. KNHANES has huge amount of health data for representative Korean population including oral health and general conditions. Based on KCNOHS, the prevalence of dental caries and its experience has decreased steadily, and the status of oral hygiene and preventive treatment called sealents has been also improved after the year of 2000. However, there is still a gap to reach to those of Western developed countries. Therefore, more effective oral health policy plans and strategies for Korean children and adolescents are needed to prevent and manage for dental caries in private and clinical field of dentistry with public sector.

건강검진이란 건강상태 확인과 질병의 예방 및 조기발견을 목적으로 건강검진기본법8)을 시행하여 국가건강검진기관평가 실시 근거가 법적9)으로 마련되어 있으며, 구강보건법10)은 정부차원의 체계적인 구강건강사업의 기획과 시행 평가를 할 수 있는 최소한의 법적 근거와 체계를 보장하고 있다. 구강보건법은 국가 및 지방자치단체가 국민의 구강건강증진을 위하여 필요한 계획을 수립·시행하고, 구강보건사업과 관련된 자료의 조사·연구, 인력의 양성 등 그 사업시행에 필요한 기술적·재정적 지원을 하도록 규정하고 있다. 민간차원에서 산발적으로 이루어지던 구강검사가 구강보건법의 제정과 함께 국가차원에서 이루어질 수 있게 되었다. 국가 단위의 구강검사를 통하여 국민의 구강건강상태에 대해 국제적, 시기적으로 비교를 하여 구강건강을 증진시키기 위한 중요성과 시급성을 파악할 수 있으며, 국민의 구강건강을 증진시키기위해 필요한 구강보건사업의 우선순위를 설정하기 위한 기초자료를 이용할 수 있다. 그러므로 국가단위의 구강검사는 국민의 구강건강상태를 측정하는 대표적인 검사이자, 국가구강보건목표의 달성여부를 판단하게 하는 중요자료이므로, 타당하고 신뢰성이 높은 자료를 획득하기 위하여 질관리가 중요하다. 따라서 구강검사의 수행과 관련하여 구강검사 인력에 대한 교육훈련을 시행하여 검진기준을 일치시키고, 현장지도를 통한 조사의 신뢰도를 확보하여야 하겠다. 뿐만 아니라 교육훈련 결과 평가에 근거한 향후 질관리 근거 자료 및 교육훈련 개선방안을 제시하여야 한다. 우리나라 국가구강검진체계는 미국의 국건영을 벤치마킹하여 상당부분 유사한 특징을 갖지만, 중앙정부나 국가조사 관련 기관이나 연구소에 구강보건을 전담하는 부서 등이 없어서 정부차원의 독자적 In Korea, two kinds of National oral health surveys have been conducted to develop various oral health indices during the past decade. The system still needs to be improved further in terms of quality control for the examination system, data management, personnel empowerment, etc. Therefore, this study compares the National Oral Health Survey system of the United States (US) with that of South Korea. The US national surveys related to oral health were set from the 1970s, whereas Korea`s national surveys have been initiated only recently; consequently, the US system is well organized and systematically managed by the professional personnel in governmental institutes, such as the Division of Oral Health in Centers for Disease Control. Furthermore, this study examines the scope of the examiner training program, and the methods for developing and implementing a standardized examination environment, data quality control, a data input system with automatic error checking, and data back up in the US. Considering the various factors involved in conducting nationwide epidemiological surveys as mentioned above, the structure and implementation methods of oral surveys in Korea clearly need to be improved.
