This study examines the details and characteristics of prizewinning plans of Cho-Sun housing plan competition promoted by Daily Cho-Sun Company during Japanese colonial period. The main features of Cho-Sun housing plan competition were that the competition held with an application of popular newspaper readers and a judging committee was composed of only Korean architects, especially Park, Gil-Ryong as the president of the board of examiners. Cho-Sun housing plan competition put ideological factors for the improvement of living as like advancing to the cultured(modem) life, respecting for family life, respecting for privacy of family members and so on. First of all, the competition suggested the direction of the improvement of dwelling spaces which focused on making harmonious home life. This study found common characteristics of prizewinning plans of Cho-Sun housing plan competition as the result. First, Cho-Sun housing plan competition introduced a centralized house plan as a model of the improvement of small-sized houses. Second, architectural orders of western or Japanese style mingled with ones of korean traditional style in prizewinning plans as entrance hall, western style reception room(parlour), maid's room, bathroom for example. And a manner of seating using chairs was brought into the style of living which would be assumed in the prizewinning plans. Third, traditional way of composing dwelling spaces was maintained, receiving the characteristics of dwelling spaces of japanese style simultaneously, which central corridor was put at the heart of house for improving arrangement of rooms and flow lines. Fourth, lavatory and bathroom were placed inside of the house.

The current study analyzed appropriateness of abandoned rice paddy wetlands as habitats for the Amphibia by assessing functions and value of abandoned rice paddy wetlands within land development districts as a habitat for living creatures and researching into the Amphibia living in the subject districts. For this purpose, the study designated abandoned rice paddy wetlands within Hwaseong A District and Pangyo B District under land development as subject lands. Those wetlands went through succession after abandonment of farming. Detailed study results are as follows. From classification of wetland types and an analysis of their characteristics, it was found that herbaceous plants such as smartweed communities, horsetail communities and reed communities, and woody plants such as pussy willow communities appeared in both districts. These abandoned rice paddy wetlands shows typical characteristics of palustrine wetlands. As a result of a vegetation structure research, it was observed that succession has been progressed for at least over 2~3 years. In assessment of wetland functions by item, it was found that they are developing into fine wetlands in terms of functions because they are ranked over Moderate Class except separate distance from streams. Also from a research into animals living in the abandoned rice paddy wetlands, it was found that main inhabitants are Rana nigromaculata,Rana dybowskii, Hyla japonica, Bufo bufo gargarizans, etc. It can be confirmed that the abandoned rice paddy wetlands are providing appropriate conditions as habitats to the Amphibia in a view that those species have life cycles of inhabitation (shores and wetlands) - egg-laying (rice paddy, puddles and swampy places) - hibernation (rice field banks and swampy places). From this point of view, it was found that abandoned rice paddy wetlands that developed because of abandonment of farming can be used as means to improve structure and functions of habitats.

Considering that few studies had paid attention to the living characteristics and social environment surrounding amblyopes, the present study surveyed the parents of children aged 3 to 12 and diagnosed-with amblyopia to analyse the time when the children were first diagnosed-with amblyopia, the characteristics of their living environment and the socio-environmental factorsand to delve into correlations. For the purpose of this study, 104 parents of patients in 4 hospitals in Seoul, Gyeonggi and Incheon consented to participate in the survey from September 2 to November 23: 2013. As for the time when the children were first diagnosed with amblyopia: the age of 4 accounted for the highest percentage(28.8%). The older the parents were: the later the children were diagnosed with amblyopia (p<.01). The higher the education of parents, the earlier the diagnosis of amblyopia(p<.05). The present findings-will be conducive to decreasing the number of patients who have no choice but to live-with low vision for life by missing some timely visual acuity tests and ophthalmological examination and particularly to developing a social safety net that can realize national medical welfare for the low-income families and the socially disadvantaged class.With the help of information technology.

This study examined the subcategories of the self concept of adolescent consumers, and investigated the influence of this self concept and the demographic characteristics on the evaluation and experience of adolescent entry into harmful places. The adolescent group was divided into 4 subgroups: (group I with negative evaluation and without entry experience, group II with negative evaluation but with experience;, group III with positive evaluation but without experience, and group IV with positive evaluation and with experience). The differences of demographic characteristic and self concept between these. subgroups were inspected. The results of this study were as follows. First, the self concept of the adolescent consumer consists of body self, social self, achievement self, scholarship self and family self. Among these self concepts, scholarship self was the highest, and family self was the lowest. Second, from the result of regression analysis using the demographic element as an independent variable to inspect the factors influencing self concept, sex, school year, living with parents, and economic status were statistically significant. Third, in case of entry evaluation, singing room was evaluated most positively among 10 places with a score of 4.20 and pub/drunkenness was evaluated most negatively. In case of entry experience, singing room was the most frequently experienced place and discotheque was the least. Fourth, with respect to demographic characteristics and influences of self concept, the influencing factors on entry evaluation were sex, school year, social self, and family self, and the influencing factors on entry experience were sex, school year, living with parents, social self, and family self. Finally, examination of the differences of demographic characteristics and self concept according to entry evaluation and experience, revealed the distinctive variables among the 10 harmful places to be sex, school year, living with parents, body self, social self, achievement self, scholarship self, and family self.

This study examined the changes in sleeping and studying patterns of young students and their mothers after moving to foreign countries. This study analyzed the relational characteristics of Geese Family members which are summarized as follows: 1) Sleeping Pattern: At the early stages of settling into foreign countries, students begin to sleep in the same bedroom with their mothers, who had used to sleep in separate bedrooms back in Korea. This change in pattern may slightly vary according to the age and gender of the students, and type of residence. Relationships between young students and mothers become more tightly coupled. However, relationships between students and fathers become less tightened. 2) Studying Pattern: Students tend to study in the public space such as the living room and dining areas, rather than in their own private rooms. This is because mothers want to support and focus upon their children's study by sacrificing normal family activities. These patterns appear stronger as their period of study in the foreign country becomes shorter and the ages of the students become younger. These studying patterns also contribute to the coupling between mothers and young students. 3) Family Relationships: From the period as Geese Families, the relation between mothers and young students become closer both physically and emotionally. The relation between fathers and children become less close. The role of fathers is degraded to that of supporter or negotiator for the time period of the mothers and child students in the foreign country.

In this study, we have carried out test to examine the ignition characteristics, such as a relation of moisture content and combustibility, and ignition temperature using KRS-RG-9000 tester, of significant part of above trees which are representative species of Young Dong Province of Korea. After rainfall, the percentage of moisture content of living leaves and branches was between 52 and 70%. But it was just between 17 and 33% after 144 hours drying at normal temperature. For dead leaves, it was 10% lower than of first. There was a significant difference on ignition characteristics. The hazard of ignition is highest on dead leaves. The ignition temperature of barks and branches is higher so a retard time is long than of living and dead leaves at normal temperature.

Disclosed is a study related to the thermal characteristics of Pinus densiflora and Quercus dentate identifying the presence of any significant difference in the above trees, which are native to Young Dong Province of Korea, according to different regions of the trees such as branches, barks, living leaves and dead leaves. For this purpose, we have carried out a cone calorimeter test focusing on the variables such as mass loss, heat release, ignition time, flame holding time and concentrations of CO and $CO_2$. The results showed that the total mass loss was greatest in tree branches, whereas the ignition time of dead leaves was fastest both in Pinus densiflora and Quercus dantata. The flame holding times of dead leaves and barks were about $640{\sim}1,016s$ and the total heat release of dead leaves was around 60.1 $MJ/m^2$, twice the total heat release of living leaves. In addition, the maximum exhaust concentrations of CO and $CO_2$ in tree branches of Quercus dentata was 2.82 times higher than those of Pinus densiflora, respectively. From the foregoing, it was confirmed that there exist region-specific differential thermal characteristics in Pinus densiflora and Quercus dentata.

Objectives: This study was performed to examine the relationship between health behaviors, living environment, and asthma in adolescents in Korea. Methods: Information on adolescents' characteristics, including demographic factors, health behaviors, and doctor's diagnosis of asthma was obtained from the Korean Youth Risk Behavior Web-based Survey (2015). In total, 68,043 middle and high school students participated. Environmental characteristics, including city park area and outdoor PM₁₀ concentrations in 2015 were obtained from the Korean Statistical Information Service. The adolescents' and environmental characteristics were merged by local information. Multiple logistic regression models were used to investigate the risk factors affecting asthma in adolescents. Results: The prevalence of asthma in adolescents in 2015 was 8.8%. In the multiple logistic regression analysis, adolescents who were male, attended middle school, suffered obesity, experienced tobacco smoking, had physical activity levels of 2 to 4 days, had higher stress levels, and lived in areas with outdoor PM₁₀ concentrations more than 47 ㎍/㎥ were more likely to have asthma, while adolescents who had middle levels of family economic status were less likely to do so. Conclusions: The fact that PM₁₀ concentration can affect asthma is an important point in this study. Risk factors identified in this study could be used as basic data for the prevention and management of asthma in Korea.

Purpose : The aim of this study was to investigate the differences in sociodemographic characteristics, instrumental activities of daily living (IADL), and healthcare needs among disabled persons with and without language disorder. Methods : Using raw data from the National Survey of the Disabled Person (2017), this study compared 6,320 disabled persons without language disorder and 229 disabled person with language disorder among 6,549 persons with disabilities. The dependent variables included sociodemographic characteristics, IADL, and healthcare needs. Results : People with language disorder were younger (p<.001), illiterate (p<.001), and had higher family income (p=.003) than people without language disorder. In addition, people with language disorder had a higher disability grade than people without language disorder (p<.001), and the percentages of brain injury, hearing impairment, and intellectual disability were higher among type of disability (p<.001). People with language disorder showed significantly higher dependence on all items of IADL than people without language disorder (p<.001). As the first-ranked healthcare need, people without language disorder had the highest percentage of "chronic illness management," and people with language disorder had the highest percentage of "disability management" (p<.001). Conclusion : The findings of the current investigation suggest that health care services are needed to improve IADL in people with language disorder and that the development of a disability management program for people with language disorder is required.
