본 연구에서는 Living Concrete의 품질특성 평가결과 유동성은 황토 혼합율 증가에 따라 테이블 플로우가 감소하는 경향이 나타났으며, 압축강도는 황토 혼합율 증가에 따라 감소하는 것으로 나타났다. 경량화를 위하여 밀도 특성 평가를 실시하였으며, 비교군으로 시멘트를 사용한 패널과 비교한 결과 시멘트 패널의 밀도에 비해 약 20 % 낮은 밀도가 측정되어 하중에 영향을 적게 받아 구조물에 설치가 가능할 것으로 판단된다. 패널온도 저감성을 평가한 결과 시간에 따른 온도 저감의 차이가 나타났으며, 이끼가 착근된 패널이 이끼가 착근되지 않은 패널보다 온도의 저감이 나타나 수직형 녹화시스템에 활용이 가능할 것으로 판단된다.

본 연구에서는 리빙 콘크리트 패널 설계시, 재료적 측면에서 모재료의 품질을 제어하기 위하여 마그네시아 복합체의 마그네시아 및 인산칼륨 비율에 따른 품질특성을 평가하였다. 품질특성은 W/B는 7수준(30, 35, 40, 45, 50, 55 및 60%), P:M 4수준(1:0.5, 1:1.0, 1:2.0 및 1:3.0 vol. %)에 따라 제조하여 평가하였다. 마그네시아 복합체의 플로우 평가결과, W/B가 증가할수록 플로우가 증가하는 경향이 나타났으며, P:M 증가에 따라 플로우가 감소하는 경향이 나타났다. 마그네시아 복합체의 압축강도 평가결과, P:M이 증가함에 따라 강도가 감소하는 경향이 나타났으나 최적의 배합비율이 존재함을 확인할 수 있었다.

The purpose of this study are to evaluate the dwelling quality of rural houses constructed with industrialized wall structures(ALC; Autoclaved Light weight Concrete, SRC; Steel Fiber Reinforced Concrete, ST'L; Steel Framed Insulating Panel), and to establish a method of dwelling quality evaluation. The questionnaire survey by mail was done, for investigating the residents' responses to indoor environment, durability, and economic aspect. The respondents are 118 residents living in rural houses constructed with industrialized wall structures. Physical elements of indoor environment(temperature, humidity, air quality, and noise level) were measured in three sample houses, which were selected considering of architectural characteristics. The findings are as follows; 1) As a result of questionnaire survey, residents' responses to dwelling quality are generally positive. 2) As a result of measurement, indoor environments of sample houses are in relatively comfortable condition. 3) As a summary of research, ALC and ST'L are evaluated as recommendable structures for a rural house.

Small apartment housings in Korea are dissatisfied due to the growing areas and changing lifestyle of the residents. Many of them currently confronted with slum areas and kinds of housing stock accumulated much more in Korean contexts. An extention of the existing small houses could be an adaptation model to the increasing requirement standards of the house residents. The new model could support diverse identification of the dwelling model in a settlement and many residents could be satisfied with the settlement. This paper deals with the unification typology of two dwelling units to one in order to remodel existing small apartment houses on the 15-pyung areas (N type) constructed by Korea National Housing Corporation in Naju. The proposed type of the merging of the dwellings remove concrete panel walls, make a path through balcony and attach a living areas to the front of the houses in order to make a circulation between the dwellings. A stair hall can be located in-between or inside the merged houses. It can also enhance privacy against conflictive activities in a house and possibly provide space appropriate for three-generation living. It can be devided for the multi-family use. Finally, the merging types of two dwelling units into one can be used as a device to get rid of the monotonous characteristics and gain diversity in the declining stock housing.

This study aims to enhance the life satisfaction of the elderly population in South Korea by exploring their satisfaction levels and identifying influencing factors. Utilizing data from the 17th Korean Welfare Panel, which includes 6,260 individuals aged 65 and older, this study employs independent sample t-tests, one-way ANOVA, and hierarchical regression analysis. The results showed that, in general, the life satisfaction of the elderly population was somewhat lower than that of the general adult population in all areas, except for job satisfaction and satisfaction with housing. Key factors influencing life satisfaction among the elderly population include demographic characteristics (gender, age, economic activity, residence, education level), subjective health status factors, financial factors (disposable income, monthly living expenses), and psychological factors (depression, self-esteem). Notably, psychological factors, particularly self-esteem and depression, profoundly affect all life satisfaction domains. Enhancing life satisfaction necessitates fostering positive self-perception and capabilities in the elderly population, suggesting the need for programs focused on positive emotional experiences. Moreover, depression significantly reduces life satisfaction, underscoring the importance of policy interventions to address negative emotions in this demographic. This study is expected to provide basic data for establishing concrete and effective policies for improving the quality of life for the elderly population. Additionally, by highlighting the importance of positive psychological factors, it is anticipated that the study will offer a new direction for improving the life satisfaction of the elderly population.

Objectives: The purpose of the study was to evaluate the effect of community intervention on reducing salt intake among college students on their knowledge, attitude and practice of low-salt diet. Methods: A community intervention planned to increase college students' knowledge, attitude and practice of low-salt diet. The intervention comprised of 1 lecture on salt and health, 4 campaigns on low-salt diet, and 2 taste testing was carried out from March 24 to May 19, 2015. All the intervention was open to entire university while data was collected from a panel of convenient sample. We used the baseline data of 251 students, 226 students completed post-test. Post-test data on knowledge, attitude, and practice, blood pressure measurement, and urine salt test were collected on May 25 and 26 by trained nursing students and graduates. Baseline data were collected on March 17 and 18. Data were analyzed using IBM-SPSS 21.0 for t-test and ANCOVA. Results: Regarding a general characteristic and health behavior, there was statistically significant difference in living arrangement(p<0.001), amount of monthly allowance(p=0.005) and frequency of eating-out(p<0.001) between the two regions in this study. However, there was no statistically significant difference in gender, major, smoking, drinking and frequency of breakfast. Regarding a characteristic related to low-salt diet, there was statistically significant difference in diastolic blood pressure level(p=0.002), urine test(p=0.001). But there was no statistically significant difference in knowledge, attitude, practice of low-salt diet and systolic blood pressure. There was no statistically significant difference in their knowledge of low-salt diet(F=1.588, p=0.209), attitude(F=2.182, p=0.141), practice(F=3.507, p=0.062) and systolic blood pressure(F=1.723, p=0.191), diastolic blood pressure(F=1.552, p=0.214), urine test after a community intervention. Conclusions: Community intervention that does not have concrete target group doesn't seem to be effective on increasing knowledge, attitude and practice of the entire community, not even in university-a somewhat closed community. It is suggested to apply a target specific intervention in order to have efficient and effective outcome from a intervention.
