This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of row-rise housing as an alternative housing type on hilly sites. Several generic solutions are proposed by considering the density of dwelling, parking plans, exterior space and access patterns, making full use of geographical features of hilly site and existing facilities. In order to promote development feasibility of proposed plans, the efficiency of the proposed techniques are verified in terms of development density, enhancement of community space, habitability of housing.

The purpose of this study is to investigate the housing affordability of multi-family dwelling in Seoul and to systemize the housing expenditure patterns and housing affordability according to household and housing characteristics. Housing expenditures are basically composed of the payments of four major items. including utilities. home alteration and interior furnishing. home mortgage debt. and monthly rent. Housing affordability index as operationally defined in this study is Housing Expenditure-to-Income Ratio (HEIR). The ratios were computed for each of the four housing expenditure items. Data for 465 multi-family dwellers were gathered from the structured questionnaire. The results showed the differences between household and housing characteristics on housing expenditure levels and HEIR. In addition. this differences had influence on future housing choice behavior. The analysis on the variables of housing choice behavior showed the result that user cost considering capital gains were less important. comparing those of early 1990's.

The purpose of this research is to determine the point of fixation of the driver during the process of driving. Based on the results of this research, the driving instructor can make a judgement on what the trainee stare on the most. Traffic accidents have become a serious concern in modern society. Especially, the traffic accidents among unskilled and elderly drivers are at issue. A driver should put attention on the vehicles around, traffic signs, passersby, passengers, road situation and its dashboard. An eye-tracking-based application was developed to analyze the driver's gaze behavior. It is a prototype for real-time eye tracking for monitoring the point of interest of drivers in driving practice. In this study, the driver's attention was measured by capturing the movement of the eyes in real road driving conditions using these tools. As a result, dwelling duration time, entry time and the average of fixation of the eye gaze are leading parameters that could help us prove the idea of this study.

Purpose: The purpose of this study was to compare depression, somatoform disorders, and quality of life among older adults. Methods: Samples of 280 community-dwelling Korean older adults were included. The age range of the participants was 60 to 90 years (average $72.6{\pm}6.4$). The participants were assigned to one of two groups based on reported scores on the Pittsburgh Sleep Quality Index from September 2006 to March 2007. The two groups were designated as "poor sleepers"and "good sleepers". A T-test was used to compare depression, somatoform disorders and quality of life between the two groups. Results: Forty-six percent of participants reported scores that indicated they were poor sleepers. Poor sleepers reported significantly higher depression scores (p<.001), higher somatoform disorders scores (p<.001), lower for each SF-36 quality of life dimension, and lower mental and physical health summary scores (p<.001) than the reported scores of those participants who were classified as good sleepers. Conclusion: Older adults with poor sleep patterns are more likely to report higher depression, more somatoform disorders and a lower quality of life. Additional research is needed to identify the appropriate nursing interventions aimed at improving sleep quality, depression symptoms, somatoform disorders and the quality of life.

The purpose of this study was to typology the integrated care needs of communitydwelling elderly, explore the socio-demographic characteristics of each type, and determine their effects on depression. The secondary data analyses using the 2017 National Survey of the elderly were conducted. The research results are as follows: First, as a result of typology patterns of care needs of the elderly based on the number of chronic diseases, ADL/IADL, dwelling satisfaction, social activities, and social support networks, three clusters were derived; 'low care needs group (LCN), 'high social needs group (HSN)' and 'complex care needs group (CCN)'. Second, compared to HSN, CCN was characterized by older, women, low educational level and urban residence. Third, the level of depression in LCN was lower than that of the HSN, and the depression level of CCN was higher. The practical and policy implications of the results were discussed.

The purpose of this study is to provide a basic data for energy efficient apartment designs by analyzing electricity and gas usage according to horizontal locations of dwelling units in apartment buildings. The data for this research are collected from J-apartment complex, located at 'Wolbae' district in Daegu City. The data are sorted into several groups according to inner and outer locations, East-West locations, and the size of units. By the performance efficiency analysis, the study derives the result as follows: 1) generally inner units are more efficient than outer units. 2) West units are more efficient than East units. 3) The group that is most efficient in overall energy consumption is West-inner units (Group-D) and the least efficient group is East-outer units (Group-A1). 4) However, as units are getting bigger, inner units consumes more energy than outer units because of the gas usage patterns. The study also established cost analysis that shows the cost differences of usages for 30, 40, 50 years between each group. The result says Inner-outer location with East-West location affects a significant amount of the management costs. In terms of economic and social life of an apartment building, energy design standards need to be tuned and make the least efficient units perform as efficient as the most efficient units to optimize the social life of an apartment building.

This study explores the daily life patterns and housing adjustment behaviors of low-income Korean elderly immigrants residing in affordable housing in the Chicago metropolitan area. Utilizing an intercultural perspective, the study focuses on identifying the immigrants' their cultural attributes of daily living and coping responses to residential misfits. These housing adjustment behaviors are classified into five modes consisting of residential mobility, structural adaptation, residential alteration, normative adaptation, and behavioral adaptation. Two-hour in-depth interviews with open-ended questions were conducted with 138 participants from 15 affordable housing complexes. Collected information includes demographic data, immigration experiences and cultural identity, daily life patterns, as well as housing evaluation and housing adjustment behaviors. The study results indicate that many research participants maintained their cultural attributes of daily living accumulated from past experiences (i.e. mostly based upon Korean cultural contexts), but also made adjustments as they complied with their aging body and new living conditions. This also reflects that immigrants' cultural needs are not limited to the use of language and ethnic goods, but are also embedded deeply in their daily life patterns to influence one's uses of the dwellings in a broader sense. All five modes of housing adjustment behaviors were observed with research participants within their residential settings. More importantly, normative and behavioral adaptations along with residential alterations occurred more simultaneously rather than sequentially when the respondents perceived discrepancy between oneself (i.e. including one's attributes, needs, and preferences) and his/her dwelling.

This study reviewed the diagnosis accuracy and evaluation criteria of the fall risk assessment questionnaire that proved validity through factor analysis in previous studies. The purpose of this study was to diagnose high-risk groups and propose personal fall risk profiles for the Korean community-dwelling elderly. The participants of this study were 439 elderly people living in S, U, B, and Y cities Korea (mean age 75.0 ± 5.7 years). Receiver operating characteristic analysis was conducted to review the accuracy of the fall risk assessment and evaluation criteria of the FRA. The results showed that the four sub-factors of the FRA: 'Potential for fall', 'Disease and physical symptoms', 'Environment' and 'Physical function', can effectively diagnose the fall risk of the community-dwelling elderly. The evaluation criteria was presented based on the sensitivity and specificity results. In addition, as a result of analyzing the patterns by the sub factors of the fall risk, the high-risk group accounted for 80% of the elderly who had problems with two or more factors. Therefore, the four sub-factors of FRA can effectively diagnose the fall risk level, and could be present individual fall risk profiles based on the evaluation criteria.

It is usual to prioritize the blocks to rearrange residential environment by the responsible officer's intuition or a few specialist's experienced knowledge. The aim of this research was to evaluate rebuilding priority in the context of spatially weighted framework integrating resident's view. The spatial weighting for the variables related to evaluation of dwelling environment was derived from AHP (Analytic Hierarchy Process) approach through the analysis of resident's view. An empirical study for a case study site has been conducted to confirm the validity for the spatial weighting. The spatial weighting has frequently influenced in changing the rebuilding priority and was identified as the important predictor for the improvement sites of dwelling environment. The spatially weighted analysis made it possible to identify area-wide patterns of rebuilding priority area subject to many different type of thematic variables, which cannot be acquired by traditional field sampling. The spatially weighting derived by integrating various formats of spatial data into a comprehensive GIS database in particular, was ideally suited to displaying the objective distribution patterns for rebuilding priority. The result of this study would play a crucial role in dealing with public complaints for rebuilding priority since it could provide objective evidences in accordance with spatial weighting.

For several years, we have conducted a series of studies on the patterns of ancient parasitism prevailing in the soil of rural and urban areas of past Kingdom of Korea. Actually, during our survey of paleoparasitology in archaeological sites of Korean peninsula, numerous ancient parasite eggs were discovered in the samples from the city districts of Hansung (Joseon) and Buyeo (Baikje), the palace moat at Gyeongju (Silla), shell-midden site at Bonghwang-dong (Silla to Joseon), and the reservoir found in Hwawangsansung fortress (Silla). By the paleoparasitological studies, with respect to parasitism in the high-density populations of ancient towns and cities, we have managed to catch glimpses of the patterns prevalent therein: a serious parasitic contamination of the soil in ancient urban areas, but not in rural areas of the past. Our historical research also proposed the plausible mechanism of parasite infection very serious indeed among urban populations in Korean history. Although city dwelling doubtless has accrued significant benefits for people and populations with agriculture, it can be equally supposed that living in such highly populated areas might have facilitated the spread of parasite infection.
