Statistical tools for determining sex in the sexually monomorphic black-billed magpie based on morphological characters have been developed based on studies of European and North American populations. However, since no morphological method has been developed for black-billed magpies in Korea, it has been difficult to conduct field studies that require information about the sex of individuals. We present two discriminant equations for determining sex of second-year (SY) and after-second-year (ASY) magpies in north- and midwestern part of South Korea. Based on morphological measurements on 105 SY (56 females, 49 males) and 72 ASY (36 females, 36 males) individuals, we found body mass, wing chord, and head length to be the most useful features for morphological sex determination. The accuracy of our method was 86.5% for SYs and 93.1% for ASYs, which is similar to values reported previously from American and European magpies. Since the equations contain morphological traits which are only minimally susceptible to seasonal variation and measurement errors, our discriminant equations should be both useful and robust for sex determination on black-billed magpies in the northern and mid-western regions of South Korea.

The purpose of this study is to study the Central Asian costumes($1{\sim}7C$) and develop new design items and suggest new brand launching. Korean apparel industry has been suffering from imbalance of supply and demand caused by the sagging economy and too many apparel companies. Due to the several years of recession, clothing consumption decreased and foreign brand's market share got bigger. As a result, managing a company became difficult and it is time for Korean apparel industry to enter the global market. We need a brand with new image and design that has big potential of purchasing power not only in Korea but also in China, and furthermore in global market. But even nearby Chinese market already became very competitive. One way of approaching Chinese fashion market is to find something special, for example, their historical background. Central Asian culture and costumes, a part of China, has both Eastern and Western culture. No other apparel industry had interest in the Central Asian costumes yet. Therefore, through their costume, a fresh design idea can be suggested.

Despite the substantial increase of the elderly population in Korea, welfare policies such as housing programs have not been developed enough to meet the diverse needs of the aging people. Particularly, caring for elderly dementia patients is becoming a serious social problem in Korean society. Families are still primarily responsible for taking care of the elderly dementia patients, and thus are suffering from tremendous caregiving burdens. In many Western countries, group homes, which are small-scale care facilities with home-like atmosphere, have become common housing alternatives for elderly dementia patients. Group homes effectively create a therapeutic environment while helping reduce the elder care burdens for the families. This article proposes to review group homes as a housing option for the elderly with dementia in Korea. The purpose of this article is to make suggestions for housing policies, separately or as a part of more general welfare policies. Based on the questionnaire survey conducted on 912 persons currently residing in Seoul and five different provinces, various possible policies and suggestions to promote establishing group homes and other facilities for elderly dementia patients are discussed in this article.

The purpose of this study was to investigate the operational characteristics of the contract-managed highschool foodservice and to analyze the factors to effect the menu price. The data was collected from 249 highschools in Seoul. The results are as follows; Those surveyed highschools were established as 1 national, 74 public, and 174 private institution. Highschools were classified as 176 academic, 66 vocational, and 7 specific purposed institution. Students were organized as 70 boys', 23 girls', and 41 coeducational highschools. Most highschool started contract-managed highschool foodservice from 1999 and the period of foodservice contract was most 3 years and the operation styles in food distribution were 96 classrooms, 105 dining halls and 17 classrooms combined dining halls. The scale of contract foodservice management companies was 63.1% small and medium and 36.9% large enterprises. The surveyed highschools had the average meal price 2,141 won per meal and they had 1,518 pupils on the register. The participating rate to the foodservice was 68.5%. The facilities investment cost of the contract foodservice management company was 179,204,230 won for private institutions and was 138,119,010 won for national&public institutions. The period of the contract was 3.22 years in private institutions, which was significantly higher than national&public institutions which showed 2.85 years. The commissary foodservice schools had higher facilities investment cost than conventional foodservice schools. Classrooms foodservice had higher participating foodservice rate than Dining halls. The investment cost for facilities showed high in order of girls', boys', and coeducational high schools, and the number on the register and the number participating in the foodservice showed high in order of boys', girls', and coeducational high schools. The number on the register showed the highest in academic and vocational schools, specific purposed institutions in sequence, and the number participating in the foodservice showed high in order of academic schools, specific purposed institutions and vocational. However, the participating foodservice rate showed high in specific purposed institution, academic and vocational schools in order, and the meal price, the investment cost for facilities showed high in specific purposed institution, academic and vocational schools in sequence. Regionally, the district south of Han river had the average meal price 2,266.13 won, which showed higher in the eastern part which had 2,033.33 won. The western part had the average investment cost for facilities of 233,331,060 won, and the central district 126,137,140 won. The number on the register showed 1845.68 in the eastern part and 1308.00 in Dong-Jak area, that had clear differences among areas. When the period of the contract went longer, the investment cost for facilities had a tendency to increase. The significant differences were existed among meal price, the investment cost for facilities, the number on the register, the number participating in the foodservice, and the participating foodservice rate. The investment cost for facilities had increased according to the number participating in the foodservice and the participating foodservice rate. And the large enterprises showed higher participating foodservice rate than the small and medium enterprises.

한반도에서는 처음으로 동해안으로부터 서해안까지 한반도를 횡단하는 측선을 따라 자기지전류 탐사를 수행하였다. 한반도의 주된 지구조 방향인 지나방향$(N30^{\circ}E)$에 수직하게 설정된 240 km 측선을 따라 $3{\sim}8km$의 측점 간격으로 50 측점에서 자료를 획득하였다. MT 임피던스는 지역에 따라 뚜렷이 구분되는 반응이 나타나며 경기육괴, 옥천대, 경상분지 서쪽 지역, 경상분지 동쪽지역에서 각기 다른 경향의 반응을 보인다. 경상분지 서쪽 지역에서는 수백 ohm-m의 전기비저항과 $3{\sim}8km$의 두께를 가지는 퇴적층이 존재하며, 퇴적층 하부에서 $1{\sim}30$ ohm-m의 매우 낮은 전기비저항을 가지는 고전도층이 발견되었다. 옥천대에서의 자료는 위상이 $90^{\circ}$를 초과하는 매우 특이한 반응을 보이고 있으며 이러한 특이성은 매우 강한 이방성 매질의 영향에 기인하는 것으로 추정된다. 경기 육괴와 경상분지 동쪽 지역은 상부지각을 구성하는 매질이 비교적 높은 전기비저항을 가지는 매질로 이루어져있기 때문에 심부 지전기 구조를 들여다 볼 수 있는 창의 역할을 한다. 1차원 모델을 적용하였을 때 경기육괴의 경우 13 km, 경상분지 동쪽지역의 경우 18 km 두께를 가지는 층이 존재하는데 이 층이 상부지각에 해당하는 것으로 생각된다.

The culture includes every possible objective forms created by humans and their shared aspects of ideas, feelings, and behaviors, beliefs and etc. The dress and its ornaments are part of the culture that expresses the relationships in objective ways and in formless immaterial ways. The school uniform represents significant meanings to the students in their school years, and it is the way of expressing their individuality and full filling their needs for self-presentation. Therefore, understanding and analyzing youth culture means understanding students' school uniform along with fast changing twenty first century civilization. Korea and Japan are very close nations to each other. Both Korean and Japanese girls' school uniform style were adopted western clothing style and went through many changes based on cultural differences between two countries. They are affected by different peculiarities between two nations and youth cultures from different cities. Therefore, this research is on analyzing how different visual values of girl's high school uniforms in Seoul and Tokyo and understanding youth cultures through macro-analysis. The youth cultures in Korea and Japan are mostly similar but there is special development on animation in Japan and possibly can find many styles of girl's high school uniform. Both nations are varying to be opened to sexual culture of adolescents but Japan is more uninhibited than Korea. In Japan, sailor-uniform can be found in fetish way in public culture. On one hand, because of most private girl's high schools in Tokyo takes an entrance examination, top-ranking students are very proud of their school uniforms and even students from other public high schools get private high school uniforms to attend school festival. This analysis showed that private girl's high school uniform in Seoul appealed as slim fitted silhouette which is close to modem woman's suit style while in Tokyo appealed as boxy style matched with short pleated skirt or sailor-uniform style. Comparing that to school uniform photos taken on the street, we can find that alikeness or more extreme styles as examples. These are influenced by different youth cultures in Seoul and Tokyo and cultural differences stands for different aesthetic norm being accepted or rejected.

This study attempts to discern the purchasing pattern of urban husbands' clothing in Korea. Studies on this subject in other cultures show that wives play lesser role in purchasing activities of their husbands' clothing in the industrial societies rather than in the pre-industrial ones. It would be interesting to know the way selecting and buying husbands' clothing in urban Korea. Specifically questions to be answered include: Who makes the decision in selecting in kinds of husbands' clothing and who buy them? Data for this study has been collected through structured questionaire survey for 606 married women in the City of Seoul including 192 mothers of elementary school students, 58 elementary school teachers, 210 mothers of middle and high school students, 56 mothers of undergraduate students, and 47 college professors. Since most women of our sample are relatively high in educational level and working for various educational institutions, the findings of this study should not be generalized as a general trend of urban Korea. Major findings of this study include: 1) Purchasing husbands' clothing is not entirely wives' domain. The degree of participation on the part of wives in selecting and buying of their husbands' clothing depends upon the kinds of clothings. If it is for such items as underwear, socks, handkerchief, or umbrella, which are relatively easy to choose in terms of size, outlook, and price, more wives do the job. Other- wise, however, husbands more actively participate in selecting and buying their own clothings such as shoes, overcoats, neck tie, and formal wear. 2) In terms of clothing behavior of husbands, it seems to be a general trend that husbands select their clothings, but wives buy them. 3) Variables related to socio-economic status seem to affect the clothing behavior of husbands. Those who more actively participate in selecting and buying their clothings include: husbands whose wives have a job outside thier family, younger in age, middle school or high school graduates rather than college graduate or husbands with far lesser education, and husbands who live in western style houses rether than in traditional Korean houses.

This study aims to analyze the vertical distribution of Asian dust measured by LIDARs at three weather stations in Baengnyeongdo (BND), Munsan (MS), and Gunsan (GS) during 10~11 May 2010, and thereby investigate their effectiveness. Asian dust passed through from central to south-western part of Korea. Although dust particles were detected over the surface in MS and GS, LIDAR data showed that the Asian dust with non-spherical particles was observed in all of the three regions. It seems that the naked-eye observation could not detect dust over the surface of BND due to the temperature inversion below a height of 0.45 km. During the Asian dust events, the duration time of dust presented 9.5 hr (BND), 19.5 hr (MS), and 24.5 hr (GS), respectively with the longest time in GS, whereas dust altitudes ranged from 0.4 to 1.3 km (BND), 0.1 to 2.8 km and 4.1 to 4.2 km (MS), and 0.2 to 2.0 km (GS), respectively, while showing the highest altitude in MS. Aerosol optical thickness (AOT) retrieved by LIDAR and skyradiometer (SR), located close to the LIDAR sites, was compared. MS (LIDAR) and Seoul (SR) attained the AOT of 0.64 and 0.50, and GS (LIDAR) and Gongju (SR) attained the AOT of 0.38 and 0.54, respectively. As SR-derived angstrom exponents (AE) during the time period determined as Asian dust by LIDAR data were 0.17 in Seoul (near MS) and 0.30 in Gongju (near GS), it can be said that the characteristics of dust particles were appeared. During the study period, depolarization ratio could serve as a useful indicator to determine dust aerosol. But, it still seems essential to conduct further investigation with longer period of data to better describe the discrepancy of AOT between LIDARs and SR.
