Most residential buildings in Korea are preferred to have maximum interior spaces, rather than consider its original design, overall building performance, and any other aspects since early 1990's. Especially in high-rise apartment buildings, balcony has been merged to living room to get more interior spaces and this renovation trends have been producing deep and narrow shapes of living rooms that was not initially intended by architects. On the other hand, the same gross area of each unit does not necessarily mean same width and depth ratio of each residential unit. Generally, we can categorize it to the deep or wide unit based on its width and depth ratio. Under these circumstances, this study analyzes the room usage pattern changes based on the space width and depth ratio and the effect of expansion of room space to the balcony. This study also includes about 180 apartments plan case studies to find out the relationships among w/d ratio changes, furniture arrangement types, and room configurations. In this research, general apartment room w/d ratios are 0.97 ∼ 1.23; 0.7(south facing sitting room), 1.23(south facing bed room), and 0.95(north facing bedroom). But, after expanding room space to balcony w/d ratio increased as follows; sitting room become 1.31, general south facing bedroom become 1.23, and north facing bedroom become 1.45. In addition to user preference of w/d ratio, many people prefer rectangular room shape a little(w/d ratio is 0.9 or 1.2) than square style (w/d ratio is 1.0) or very deep room style (w/d ratio Is more over 1.5). Accordingly, expanding the room space to balcony may make unsatisfactory room w/d ratio. Expanding room space to balcony should be considered by existing room w/d ratio.

The purpose of this study were to find out the difference of needs of caring between care-givers and non care-givers, and to suggest the way of lessening vigorous task of care-givers for the elderly with dementia. Data were collected from 130 nationwide respondents intentionally divided into two groups; care-givers and non care-givers in the middle aged with middle and upper income. Collected data were analyzed by frequency, percentage, t-test using SPSS package. Since the result of survey, unexpectedly, showed no difference between two groups, it could be explained as that these two groups commonly had same needs of caring for the elderly with dementia. Major findings were as follow; 1) Most Koreans stiff thought family should be the main care-giver for the elderly with dementia prior to nation or society. 2) Responsibility of caring for the elderly with dementia would be better to be shared with children instead of focusing to a child. 3) They thought ideal residential facilities for the elderly with dementia were small-scale professional dementia facility(group home) rather than home or general elderly housing. 4) Professional dementia care hospital was one of the most needed facilities for the elderly with dementia, followed by short-stay and dar-care center. 5) It was revealed care-giving task was vigorous showing that most care-givers spent 1-5 hours a day for caring, while 13% of respondents spent 11-24 hours a duty. 6) 90% of care-givers took the responsibility of main care-giver because of duty of offsprings or spouses, and wanted to be free from their current circumstances. From the result of this survey researchers would like to suggest the establishment of diverse facilities for professional dementia care to lessen the caring burden for the elderly with dementia: group home, chronic hospital, short-stay, day-care center. Financial support from the government for the housing renovation of the caring families should be considered seriously afterward. It is needed to give the opportunity to select proper paid dementia care facilities according to their income and situation of household.

Background: Several potential risk factors have been identified for diffuse large B-cell lymphoma (DLBCL); however, epidemiological studies investigating the association between these risk factors and DLBCL have yielded inconsistent results. Objectives: To investigate potential medical, lifestyle, and environmental risk factors of DLBCL in Shanghai, China through a hospital-based case-control study. Method: One-hundred-and-forty-seven newly diagnosed DLBCL patients and 294 sex- and age-matched controls were recruited from 11 hospitals in Shanghai between 2003 and 2007. A standardized structured questionnaire was used to obtain patient data on demographics, medical history, family history, lifestyle, and environmental exposures. Conditional logistic regression models were used to estimate odds ratios (ORs), with 95% confidence intervals (CIs), for risk associated with each data category. Results: History of tuberculosis (TB) infection and "living on a farm" were positively associated with DLBCL (TB: OR=3.05, 95% CI: 1.19-7.80; farm: OR=1.82, 95% CI: 1.21-2.73). In contrast, taking traditional Chinese medicine was negatively associated with DLBCL (OR=0.36, 95% CI: 0.14-0.89). No significant correlation with DLBCL risk was found for any of the other potential risk factors (p>0.05), including but not limited to hair dyes, alcohol drinking, smoking, and home/workplace renovation within one year. Conclusions: Consistent with results from previous studies in other DLBCL case populations, traditional Chinese medicine appeared to have a direct or indirect protective effect against DLBCL. However, this study also identified a possible predisposition for DLBCL in TB sufferers and farmers.

This study found the possibility of using cemeteries within the locality as field trip destination. A comparison between Korea and the United States of America's active progress has derived the difference and the implications. Therefore, this article found that the cemetery has sufficient resources based on experience-learning place within the community. Therefore, when the active educational program was developed; it gained more abundant resources for education, as well as provided more different educational opportunities for the students than now. As the result of comparison, the reason why the educational program is actively progressing in the American cemeteries is that a beautiful and fresh environment has been built up such as a park or garden in a cemetery and has been preserved as a healthy forest ecosystem. Furthermore, it is because they actively used the cemetery within a community as the subject. If our cemetery can be renovated and the funeral culture can be changed to break down the image of an avoidable unpleasant facility, it would play a role as a field for learning experience.

Space extension and the increase of the number of households are helpful to raise business value of the remodeling through the renovation of apartment houses that is required by residents of new cities and large-scaled apartment. However, in the case of accepting this demand, it could have a bad influence on the landscape of a complex in terms of the structure of apartment houses and the safety of construction and urban planning, and a problem occurs in the aspect of fairness for reconstruction. For the study, the current status related to the remodeling system through laws, related articles since 2000 and research data was analyzed. In addition, the individual quantitative analysis was conducted in the four aspects to judge whether households expansion for remodeling is plausible:1) Statistical data to comprehend the changes of population and social structure 2) Survey data of floor space index and the building-to-land ratio of new cities at the intial stage for the review of the effect of architectural planning and urban environment 3) Surveys of experts on structural safety in order to judge whether the demand of expansion is accepted or not. 4) Quantitative analysis of each item to compare fairness with reconstruction. Therefore, this study is intended to understand problems of the remodeling system that is currently operated. Moreover, it will be further reviewed that the expansion of households is feasible through the permission of expansion and it will be discussed that the revitalization of the apartment remodeling has a positive impact on the residential environment.

Water quality in the public water course has been polluted more seriously than ever before due to the increase of the number and aremount of pollution sources such as domestic and industrial wastewater. For water quality conservation, the Korean government has been trying to construct sewage treatment facilities continually, of which treatment capacity reached to 11,452,400m$^{3}$/day in 1996. Night soil treatment facilites of m nationwide have the treatment capacity of 24,038m$^{3}$/day. But water quality has not been improved because the sewer systems were insufficient and the treatment efficiencies of sewage were not high, enough. For renovation of water quality, miscellaneous domestic wastewater must be treated because 27g BOD/day out of total 40g BOD/person-day come from miscellaneous wastewater, comparing to 13g BOD/day from night soil. However, sole treatment purifier treat only night soil from the flushing toilet. Therefore, it may be desirable to treat the miscellaneous domestic wastewater and the night soil from flushing toilet together by joint treatment purifier system as on-site domestic wastewater treatment technology. In Korea, the joint treatment purifier system, introduced in 1997, have the benefit as follows; i) good water poiluion control effect, ii ) good effect on river water flow, iii) water pollution control with sewage treatment facility, and iv) rapid pollution control effect, etc. In order to achieve a good effect as stated before, i ) strengthening effluent guideline including BOD, nitrogen and phosphorus, ii ) specializing operation to maintain high performance, and iii) supporting its construction and maintenance costs by the governmental level may be necessary: In addition, automation system of joint treatment purifier, technology for its package and compactness, and a new bio-media bio-filter with higher capacity should be further developed in agreement with a more stringent effluent guideline.

Purpose: G-SEED's evaluation of existing buildings in Korea is an important point because the energy consumption and CO2 emissions of existing buildings are continuously increasing due to the aging of buildings over time. In 2016, the government has set up a 'Green Remodeling Certification Standard' in G-SEED in order to revitalize the green remodeling business of existing buildings. As a result, G-SEED is distinguished between buildings with green remodeling and buildings with general remodeling. Therefore, this study analyzed the system of the certification of the green remodeling building which is aimed at improving the performance of the building. Method: First, we analyze characteristics of the existing building certification standards of G-SEED(Korea), LEED(USA), and BREEAM(UK). Second, the evaluation criteria are based on the G-SEED Green Remodeling Certification, 2016, LEED for BD + C: New construction and major renovation v.4, BREEAM UK Non-Domestic Refurbishment and Fit-out 2014. Based on the analysis results, we propose the improvement direction of G-SEED Green Remodeling Certification Standard. Result: Existing buildings should be classified into 'existing building certification' for re-certification and 'green remodeling certification' accompanied by building performance improvement. In addition, building green buildings through performance improvement should include not only energy performance, but also creating a pleasant indoor environment and minimizing environmental impact. Finally, existing buildings have accumulated information on energy and resource use, and a performance improvement plan should be established based on this information.

In the field of architecture, the sustainable architectural concept, "green buildings," has been suggested as an alternative to solve the environmental problems; however, the concept has not yet been converted to awareness and development of related technology. The leading role of public sector has been socially and economically influential in the nation, hence green public buildings are significant to stimulate the spread of green buildings in the nation. This study is to draw an appropriate method of implementing the green building concept to the two main government office buildings of Jeju Special Self-Governing Province based on the plan to improve the work environment; it is also to provide long-term directions of implementing policies and reference for the public and private sector to utilize the green building concept. Its research methodology was the survey method. A total of 142 questionnaires were returned by government employees of the two buildings. It accounts for 20% of the total number of 711 workers of the buildings. According to the analysis of the returned questionnaire, the majority of the surveyed have a positive evaluurned toward the introduction of green buildings due to their expecturned for the possible i the buildingstheir work environment. In addition, they showed more interest in space planning with natural ventilation than automatic systems regarding applied methods for green buildings.
