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.

Objectives: The purpose of this study was to evaluate the effects of oral care interventions on stroke patients in the intensive care unit (ICU). Oral hygiene levels, periodontal health, and presence of Candida were evaluated in patients who received an oral care intervention and control patients who did not receive the intervention. Methods: In this study, 22 stroke patients who were admitted to the ICU between June 2011 and August 2012 underwent oral examinations and were provided with an oral care intervention that included tooth brushing with an interdental brush and the use of a chlorhexidine mouthwash (oral care group), while 21 patients who were admitted to the ICU during the same period did not receive the oral care intervention but underwent oral examination and served as controls (non-oral care group). In the oral care group, oral care was performed once a day for 1-5 weeks according to the general health of the patient. The patients in the oral care group underwent oral examination before and after the oral care intervention. Plaque index, gingival index, clinical attachment loss (CAL), and presence of Candida were evaluated in both the groups. Results: The plaque index and gingival index of the oral care group were significantly lower than those of the non-oral care group; however, no significant difference in CAL was observed. The levels of Candida in the pra; care group were ;ower than those om the non-oral care group. However, no significant intergroup difference was observed in the levels of Candida. Conclusions: Oral care interventions improved oral health, including oral hygiene and periodontal health, of stroke patients in the ICU. Therefore, this study showed that oral care interventions can be effectively used to improve the oral health of stroke patients in the ICU.

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.

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.

Objectives: To examine the difference in oral health status of Korean adults according to geographic location. Methods: Using raw data of National Oral Health Survey 2000, the 112 administrative districts were categorized into metropolis(gu: ward of large city), urban(si: city except metropolis), and rural(gun: county) areas. The averages of decayed surfaces/teeth (DS/DT), missing surfaces/teeth (MS/MT), filled surfaces/teeth (FS/FT), DMFS/T, and Community Periodontal Index (CPI), and the proportion of prosthetic treatment need were calculated in each administrative district. Mean age, the number of population in 2000, the proportion of elderly people, the number of privately owned cars, per capita production from manufacturing industry, and the number of medical facilities per 1,000 were obtained as contextual factors. Regression analysis was done to test the regional difference of oral health status including geographic location, mean age, per capita production from manufacturing industries, and the numbert of medical facilities per 1000. Results: The crude averages of oral health indices (DMFS/T, CPI) reflecting the experience of dental caries and periodontal health was significantly higher in urban and rural area than those in metropolis region. The proportion of prosthetic treatment need in urban and rural area was also higher than that in metropolis. In the final regression model adjusted after socio-environmental factors, DS, DT, CPI, and the proportion of prosthetic treatment need in rural region were higher than in metropolis (p<0.05). FS and FT of rural area were lower than those of metropolis. Conclusions: Regional difference in oral health status existed in Korea. This regional difference may be attributable to dissimilar age distribution of each district but socio-environmental factors are still prone to affect this disparity.

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.
