A wind tunnel study has been carried out to determine the influence of spacing between buildings on wind characteristics above rural and suburban type of terrain. Experiments were performed for two types of buildings, three-floor family houses and five-floor apartment buildings. The atmospheric boundary layer (ABL) models were generated by means of the Counihan method using a castellated barrier wall, vortex generators and a fetch of roughness elements. A hot wire anemometry system was applied for measurement of mean velocity and velocity fluctuations. The mean velocity profiles are in good agreement with the power law for exponent values from ${\alpha}=0.15$ to ${\alpha}=0.24$, which is acceptable for the representation of the rural and suburban ABL, respectively. Effects of the spacing density among buildings on wind characteristics range from the ground up to $0.6{\delta}$. As the spacing becomes smaller, the mean flow is slowed down, whilst, simultaneously, the turbulence intensity and absolute values of the Reynolds stress increase due to the increased friction between the surface and the air flow. This results in a higher ventilation efficiency as the increased retardation of horizontal flow simultaneously accompanies an intensified vertical transfer of momentum.

The urban modernity that became an irresistible model for elites in Asia in the decades before and after 1900 was far from being gender-neutral. It represented an exceptional peak of patriarchy in its exclusion of respectable middle class women from the work force, from ownership and control of property and from politics. Marriage was indissoluble and the wife's role in the male-headed nuclear family was to care for and educate the abundant children she produced. Puritan religious values underlined the perils for women of falling outside this pattern of dependence on the male. Though upheld as modern and civilized, this ideal was in particularly striking contrast with the pre-colonial Southeast Asian pattern of economic autonomy and balance between women and men, and the relative ease of female-initiated divorce. Although attractive to many western-educated Southeast Asian men, including religious reformers determined to 'save' and domesticate women, urban respectability of this type was a poor fit for women accustomed to dominant roles in commerce and marketing, and at least equal ones in production. Southeast Asian relative failure in the high colonial era to adapt to the modern market economy may also have a gendered explanation. We should not be surprised that patriarchy and puritanism became more important in Southeast Asia as it urbanized in the late 20th Century, since this was echoing the European experience a century earlier. The question remains how far Southeast Asia could retain its relatively balanced gender pattern in face of its eventual rapid urbanization and commercial development.

The purpose of this study was to identify the effects of parent-child relationship perceived by university students on value of marriage and partner selection criteria. Questionnaires were distributed to 467 university students with questions covering topics including general personal information and characteristics, parent-child relationship, value of marriage and partner selection criteria. To analysis the data, t-test, ANOVA, and two step cluster analysis was used. The female group A with passive parent-child relationship had high level of negative value of marriage, male group D with active parent-child relationship had high level of romantic and instrumental value of marriage. The male and female passive group considered external condition as a partner selection criteria more than male and female active group does. As a partner selection criteria, passive male group recognized internal condition more than passive and active female group does. and active female group recognized situational condition more than passive male group does. This study reveals that university students' parent-child relationship does have an effect on their value of marriage and partner selection criteria. It is therefore proposed that diversify objectives and education content of family life education should relate not only to individuals' value of marriage but also to their parent-child relationship.

The purpose of this study was to investigate types of well-being oriented consumption values that lead to well-being food consumption behaviors, as well as to identify the variables influence well-being food consumption. A survey of 579 women aged 20 or more was conducted through azoomma.com, an online portal site. The findings of the study were as follows: The level of well-being food consumption was above the mid-value for all categories, with the exception of food with added ingredients. In addttion, multiple regression analysis indicated that approximately 22.7% of the environmentally friendly foods consumed were chosen based on emotional value, degree of price perception and educational level. Conversely, 20.8% of the confectionaeries consumed were chosen based on emotional value, age, degree of price perception, average monthly income, and functional value. When food with added ingredients were considered 16.6% of those were chosen based on emotional value, social value, and degree of price perception. Finally, 29.3% of cereals and fish consumed were chosen based on emotional value, degree of family's health, and social value.

biotic indices scoring with the benthic macroinvertebrates were assessed as pollution monitoring tools in the north branch of the Han River system, Korea. We investigated the temporal variability of water quality at unpolluted, moderately polluted and heavily polluted sites using several biotic indices and assessed appropriate biological monitoring indices for lotic systems in Korea. The following biotic and chemical indices were employed in order to compare their applicability to the lotic systems : Trent Biotic Index (TBI), Chandler's Biotic Index-Average Score per Taxon (CBI-ASPT), Modified Biological Monitoring Working Party Score System-Average Score per Taxon (BMWP-ASPT), Hilsenhoff's biotic Index (BI) and Family-level Biotic Index (FBI) models for biotic analyses and National Sanitation foundation's Water Quality Index (NSFWQI) and comprehensive Chemical Pollution Index (Pb/n) for chemical analyses of water quality. Index and score values were compared with each other and with 24 water chemistry parameters. All biotic indices were significantly auto-correlated (p<0.001) and BI and FBI/ROK among them were highly correlated (r=0.84). BI and BMWP-ASPT models were also highly correlated with NSFWQI, while TBI values showed high correlation with the Pb/n. The BI and BMWP-ASPT were highly correlated with the most water chemistry parameters. We conclude that the BI model, which includes indicator species and abundance of taxa, is best suited for the bioassessment of lotic systems in Korea. For rapid field-based assessments, FBI/ROK and BMWP-ASPT models are also appropriate.

The purpose of this study was to examine whether childbirth encouragement policy is actually helping those childbirth, and also discuss the possible directions of this policy to unfold in the future, should take. For this, We have surveyed 412 married and 437 unmarried men and women in order to investigate the individual values that influence childbirth, From these respondents and we interviewed and surveyed recipients of grants (244people), administrative officers in charge (41people), and experts (34people) to investigate their social view on the Korean government's impact. The results of this study are as follows: Firstly, most of the people (unmarried 70.3%, married 69.1%) surveyed said that important life objectives for them. Secondly, most of the people(male 44.4%, female 73.8%) surveyed said that once married shied away from having babies, (a) due to the finance and childcare burden is heavy of running a family while both parents are fulltime employed (b) because it is difficult to get pregnant due to health problems, and (c) foremost because having several children exacerbates their financial burden. Thirdly, grant recipients(75.4%), administrative officers in charge(65.9%), and experts(53.0%) all said that childbirth encouragement policy currently being implemented has little impact on their childbirth. Finally, it was established that the incentives to encourage childbirth is best suited for individuals that favor having many children.

Collaborative consumption (CC) occurs in organized systems or networks in which participants conduct sharing activities in the form of renting, lending, trading, bartering, and swapping of goods, services, transportation solutions, space, or money. Information and communications technologies (ICTs) that have emerged with CC. CC is expected to alleviate social problems such as hyper-consumption, pollution, and poverty by lowering the cost of economic coordination. In this study, we investigate the influence of educational experience and expected benefits of CC participation (intended to using and providing CC) of Adolescent Consumers. The subjects for the study were 418 high school students. Data was analyzed through frequency analysis, mean, standard deviation, t-test, ANOVA, Pearson's correlation, and hierarchical multiple regression analysis using SPSS Win 21.0. The results of this study are as follows. First, the significant positive relationship found between CC participants (intent to use and provide CC), educational experience (home education, school education, and mass media) and expected benefits (social benefit, economic benefit, enjoyment, community effect, and reputation). Second, enjoyment, mass media, reputation, social benefit, home education and school education values were variables that influenced the using participation intention for CC. Third, the major variables influencing the providing participation intention CC were home education, enjoyment, gender, community effect, and mass media values.

The recent global economic crisis has resulted in increased discussion and attention on the sharing economy, a form of economic activity where individuals share currently available products. This study investigates consumer sharing economy usage attitudes and usage intentions by applying rational choice theory. For this study, an investigation that had 400 adult consumers from across Korea answer a structured questionnaire was conducted. A statistical approach using SPSS ver. 22.0 was used to analyze the data. The study found that the consumer's sharing economy value and participation levels were higher than usual. Higher than usual consumption patterns were seen for the construct of rational behavior theory. An analysis of the relative influence of variables regarding sharing economy usage intention also found that usage intention was higher for those who had experienced using a sharing economy services rather than those who did not have experience. In addition, the sharing economy usage intention also increased along with the values for subjective norms, sharing economy usage attitudes, sharing economy participation, sharing economy emotional benefits, and increased values. This study found that fundamental materials for consumer education should be made to eliminate difficulties that consumers have when they use sharing economy services. It is also expected that economic policy will develop to stimulate the sharing economy in a stable manner, that sharing economy-related information will be provided to consumers, and that consumer policies will be prepared to prevent consumer problems before they occur.

This paper deals with multiresolution analysis of wavelet transform for partial discharge(PD), composite discharge(corona + surlace discharge). Multiresolution analysis was used for performing discrete wavelet transform PD signals was decomposed into "approximation" and "detail" cOmpJnents until 4 levels by using discrete wavelet analysis. In this paper, daubechies family is adopted for the research of the characteristics of PD signals. 1be results show that in corona discharge the segment 7, 8, 9, 10, 1] values of defined variable is increased with discharge process, so phase distribution is characterized by 210~330 ranges. In case surface discharge in expoxy insulator inserted, defined variable values is fairly symmetric chscharge pattern because coupled both corona and dielectric oounded discharges. We can confimJly discriminate the type of PD source.

The purpose of this study was to examine the diverse situations and housing related consciousness affecting baby boom generation's housing and to propose new possible housing alternatives for Korean baby boom generation for their old ages. Surveys were used to conduct 1:1 interviews with the baby boom generation. This study analysed the baby boom generation's housing related consciousness regarding living in old age with/apart from their children, sense of responsibility to their children and parents, expectations of support from their children in old age, current preparedness for old age, reasons for difficulties in realizing plans for housing in old age, and housing values in old age in order to examine this generation's diverse view in relation to preparations for housing in old age. Based on the results of the analysis of variables of housing consciousness in relation to old age by each characteristic of the baby boom generation conducted in investigations of the present study thus explained, housing alternatives in old age were 1)family exchange-type housing in old age 2) multihabitation-type housing in old age 3) housing in old-age with workplaces.
