In Korean traditional architecture, the Gong-po style is divided into the Jusimpo, Dapo and Ikgong. Jusimpo and Chulmok-Ikong, where only Gong-po is placed on the column, differ in form of Gong-po depending on the viewpoint. Since 'Chulmok-Ikgong' has been generally regarded as 'One Chulmok-Two Ikgong', the precedent researches have been conducted mainly on 'One Chulmok-Two Ikgong' in the Gong-po style classification. However, when it comes to 'One Chulmok', the style of Ikgong can be organized from the one to three steps and this study is particularly for examining the occurrence and transformation of 'One Chulmok-One Ikgong'. One of the case study sites, Bonghwa Cheongamjeong was originally built in the 16th century, and is believed to have been repaired from 'Non Chulmok-One Ikgong' to 'One Chulmok-One Ikgong'. Since the beam linked directly to the upper part of a capital, it does not connect the eave trave(architrave) in between. Also, Soro which supports Jangyeo(the architrave strip) has been placed and linked in comparatively lower position. It is confirmed by the signigicant difference in the hierarchy of Gong-po forms in one architecture. The Jeonju-Hyanggyo Daeseongjeon, which was built in the 17th century among the subjects, was similar with 'One Chulmok-One Ikgong', but it was found to be the type of Jusimpo form because the bottom of the beam and the top of the Ikong are apart. And Gongan is confirmed at Cheomcha. In the 17th century, it can be seen that Heot-Cheomcha disappeared and Ikgong was started to use as a constant figure. The end of the 18th century, it can be seen that it was changed into a ornament added on Haeng-gong, being seen in the case of Hwaseong Dongjangdae. In conclusion, it can be seen that 'One Chulmok-One Ikgong' were developed in both the Jusimpo and Ikong style. The transformation into 'One Chulmok-One Ikgong' was inevitable consequence related with an elevation difference between the eave trave and the column trave.

This study was to investigate the preference tendency by detail and material preference of summer one-piece dresses for the children, and evaluation standard of children's wear in purchasing one-piece dresses as an object of mothers who have girls as buying representatives of children's wear in order to supply real information of design about the one-piece dresses for the girls in accordance with the consumers' demands. The results of this study revealed that the one-piece dress was favorite one to them in purchasing their summer wear. This study showed tendency that the more the mother's fashion interest was, the more the mother's preference on the one-piece dress was. As to the material preference of one-piece dress, it preferred the natural fiber to the synthetic fiber much, and the preferred customer order in purchasing one-piece dresses for their children was analyzed as activity, material, design collar, and pattern. As to the preference by form factor of one-piece dress, it preferred A-line silhouette in the silhouette, natural waist in the waist position, 5~7cm from the knee in the length of one-piece dress, and flared skirt in shape of skirt. The preference on the collar type was soutien collar, and the preference on the neckline type was round neckline. In addition, the preference on sleeve form was shirtsleeve, and the preference on trimming was lace trimming.

Objectives: The aim of this study was to investigate the effect of glide path preparation with PathFile and ProGlider nickel-titanium (NiTi) files on the cyclic fatigue resistance of WaveOne NiTi files. Materials and Methods: Forty-four WaveOne Primary files were used and divided into four groups (n = 11). In the first group (0 WaveOne), the WaveOne Primary files served as a control group and were not used on acrylic blocks. In the 1 WaveOne Group, acrylic blocks were prepared using only WaveOne Primary files, and in the PF+WaveOne group and PG+WaveOne groups, acrylic blocks were first prepared with PathFile or ProGlider NiTi files, respectively, followed by the use of WaveOne Primary files. All the WaveOne Primary files were then subjected to cyclic fatigue testing. The number of cycles to failure was calculated and the data were statistically analyzed using one-way analysis of variance (ANOVA) and the Tukey honest significant difference multiple-comparison test at a 5% significance level. Results: The highest number of cycles to failure was found in the control group, and the lowest numbers were found in the 1 WaveOne group and the PF+WaveOne group. Significant differences were found among the 1 WaveOne, PF+WaveOne, and control groups (p < 0.05). No statistically significant differences were found between the PG+WaveOne group and the other three groups (p > 0.05). Conclusion: Glide path preparation with NiTi rotary files did not affect the cyclic fatigue resistance of WaveOne Primary files used on acrylic blocks.

We have performed eight, single transplantations of right lung in dogs from September, 1988 to March 1989 at the Thoracic & Cardiovascular Surgical department, Yonsei University, College of Medicine, Seoul, Korea. We wrapped bronchial anastomosis site with great omentum and used cyclosporin in preoperative and postoperative periods in seven cases except one. The one without wrapping the bronchial anastomotic site with omentum and using cyclosporin died due to bronchial anastomotic site rupture in postoperative fourth day. If there is no reason to choose one side over the other, we would generally choose to do left-sided transplant as this is technically somewhat easier because of the long length of recipient bronchus and the ease of clamping the left atrium proximal to the pulmonary veins. The right atrium limits the amount of left atrium that can have incorporated into the clamp proximal to the pulmonary veins on the right side. But we had chosen to do right-sided transplant of lung because we must take variable technical experiences on right sided lung transplant in dogs. We have to anastomose one of pulmonary vein and left atrial wall on right-sided transplant easily only with double ligation of one pulmonary vein because right atrium limited the clamp of left atrium proximal to pulmonary veins with decreased venous return and cardiac output in some dogs. All seven dogs with right-sided lung transplant had survived more than one day with good condition except one. The one dog have to be sacrificed to evaluate the difference between the gas analysis in pulmonary venous and arterial blood in post-operative eight hours. We found hemorrhagic pulmonary edematous changes of contralateral left lung in this dog. And also all dogs have to be sacrificed for the evaluation of surgical problems, anytime in post-operative periods without any cardiopulmonary resuscitative efforts when the general condition would be worse progressively. We found no any surgical technical errors in seven dogs except one with thrombi in suture site of left atrium. There were hemorrhagic pulmonary edematous changes of transplanted right lung in one, of contralateral left lung in one, of contralateral left lung with double ligation of its pulmonary artery in one, thrombi around left atrial sutures sites in one, multiple air leakage in one bronchial rupture in one due to rejection or infection. There were accidental extubation and delayed intubation in one and unknown cause of death in one.

Korea has successfully achieved a lowered fertility level owing to the strong population control policy and effective family planning program. Along with fertility decline and decreased number of children in family, average number of household members has decreased and nontraditional households such as one person household and households composed of unrelated individuals have prolifirated, even though the absolute number of them are found minimal in Korea. However in recent years several data and survey results suggest that one person households are gradually in the increasing trend. The study aimed at investigating the real state of one person households in Korea and next analyzing the proportional distribution of one person households by a few socioeconomic characteristics, thus providing basic for eatablishing far-singhted population and social welfare policy in the future. Korea has experienced high growth rate of economy through government-led development plans starting from the 1960s. During the past three decades, Korea has shifted from the agricultural state to the industrialized one. In compliance with the economic growth, urbanization and industrialization have brought about rural-to-urban migration and a great bulk of young population migrated to urban areas, who are seeking for educational and job opportunities. Korean society has also been under drastic change in every aspect of life involving norms, tradition, and attitude, etc. Therefore, in spite of the prejudice on 'living alone' still remaining, young people gradually leave parents and home, and further form nontraditional households in urban areas. Current increase in the number of one person households is partly attributable to the increase in high female educational attainment and female participation in economic activities. As the industrial structure in Korea changes from primary into secondary and tertiary industries, job opportunities for service/sales and manufacturing are opened to young female labor force in the process of industrialization. Contrary to the formation of one person households by young people, the aged single households are composed when children in family leave one by one because of marriage, education, employment. In particular, a higher proportion of aged female single households occur in rural areas due to the mortality difference by sex. Based on the data released form the 1990 Population and Housing Census and National Fertility and Family Health Survey in 1985 and 1991, the study tried to examine the state of one person households in Korea. According to Census data, the number of one person households increased to 1, 021, 000 in 1990, comprising 9.0 percent of total households. And the survey reveal that among total 11, 540 households, 8.0 percent, 923 households, are composed of one person households. Generally, the proportion of female single households is greater than that of male ones, and a big proportion of one person households is concentrated in the 25-34 age bracket in urban areas and 65 years and more in rural areas. It is shown than one person householders in urban areas have higher educational attainment with 59.2 percent high schooling and over in 1991, Job seeking proved to be the main reason for leaving home and forming one person households. The number of young female single households with higher education and economic self-reliance are found nil and the study did not allow to analyze the causal realtionship between female education and employment and one person household formation. However more research and deep analysis on the causal facors on one person household formation using statistical method are believed to be necessary.

중국의 신(新)실크로드 구상인 일대일로(一帶一路) 전략은 중국 내륙지역을 중심으로 한 육상 실크로드와 연해지역을 중심으로 한 해상 실크로드로 나뉜다. 육상 실크로드는 대외교류 확대를 위해 주변 인접국가와의 인프라 연결 및 무역원활화 추진에 더욱 역점을 두고 있다. 해상 실크로드는 해상 인프라 구축과 해양 협력 강화를 일대일로 전략의 핵심으로 제시하고 있다. 본 연구에서는 일대일로의 오통 중에 경제협력과 가장 관련이 깊은 인프라, 자금, 무역 부문의 일대일로 진행상황에 대해 데이터를 기반으로 평가를 개괄하고, 아시아 국가와 특히 중국의 경제에 의존도가 심화되고 있는 북한의 일대일로 전략의 진행상황을 분석하였다. 중국은 일대일로 전략을 아시아 국가들과 인프라 연결을 위한 협력 체계 및 계획을 수립하고 협력 프로젝트를 추진해왔다. 그러나 아직까지 관련 프로젝트의 실행은 초기 단계에 머물러 있는 것으로 파악된다. 자금융통은 그 수준이 높지 않으며 지역별, 국가별, 항목별 격차가 크고 앞으로도 빠른 발전은 어려워 보인다. 무역창통 수준은 인프라 연결이나 자금융통보다 활발하게 무역교류와 투자협력이 이루어지고 있음을 보여주고 있다. 최근 글로벌 경기 침체에 따라 중국의 전체 무역량은 감소하였지만 일대일로 아시아 국가들과 무역규모는 크게 증가하였으며, 투자협력도 직접투자규모가 크게 증대되고 있음을 파악하였다. 아울러 일대일로 추진에 있어서 중국의 ICT 기업의 활약이 두드러지면서 중국의 디지털 일대일로가 아시아국가로 빠르게 확산되고 있다. 중국의 ICT기업은 일대일로의 인접국가인 동남아를 공략하면서 기술 수출과 콘텐츠 수출 등의 방식을 통해 현지에 서비스와 기술 지원을 제공하고, 문화 융합을 추진하는 등 디지털 트랜스포메이션을 주도하고 있다.

This study explored contemporary furniture theory and practice in Postmodernism mentioned as one of a kind furniture based on ideas from the tradition since Modernism. Qualitative conceptual analysis as the principal methodology was used to explore the postmodern furniture adopting or reflecting ornament from the tradition presented as postmodern furniture designers' point of view differently and variously. Thus, the examples about one of a kind or one-off furniture were dealt with Postmodern ideas appeared in the doubt over Modernism, Post-Modern furniture ideas from the traditional and Modern architecture, ornamental ism, Postmodern theorists, Postmodern furniture and the criteria. As a result, although one of a kind furniture design appealed newly from and based on the ornament of the tradition has been identified as new design like one of a kind furniture which shows lack of function, the piece with the meaningful ornament makes people happier in their daily life. Hence, one of a kind furniture, a work of art, has been required as striking a balance both function or comfort and aesthetics or beauty which makes the people more enjoyable.

Wide-spread practitioner literature exists for the one-to-one marketing effect from a firm's perspective; however, limited research discusses the psychological effect of one-to-one marketing from a consumer's perspective. The authors test a model that integrates the level of consumer-perceived one-to-one marketing effort (OTO-E), instrumental (i.e., perceived usefulness) and affective benefits (Le., pleasure and arousal), and attitude toward the e-store (ATE). The analysis of an online survey (conducted with 195 U.S. undergraduates) confirms the positive effect of level of OTO-E on the benefits that influence ATE. In addition, it reveals the positive effect of the affective benefits on the instrumental benefit. The results expand the current research on the value of one-to-one marketing by presenting a consumer-oriented approach. As the study was conducted in the U.S. market with intense consumer demands for individuation of service, the results should provide useful managerial/ theoretical implications to Korean apparel e-tailers, concerning their future implementation of one-to-one marketing.

Recently, one-person households have surpassed nuclear families. One-person households are expected to have many problems with health due to an irregular life style and a tendency to be more isolated from society. In addition, we need to divide the generations and survey each generation due to differences in one-person household factors and characteristics as well as the unique physical conditions of each generation. Therefore, based on the sixth Korea National Health and Nutrition Examination Survey, this survey examined health behavior differences between one-person households and non-one-person households according to generation (respectively) as well as studied how one-person households and health behavior influence subjective health conditions. The major result of this survey is as follows. First, one-person households reveal a higher rate in the negative health behavior than non-one-person households. Second, the physical activity of all households reveals a high rate of non-activity. Third, health scores of one-person households are lower than that of non-one-person households; consequently, the analysis of health scores for one-person households and non-one-person households indicated that the middle age health scores for one-person households have been lowest in generations. Fourth, the factors that influence subjective health conditions indicated that one-person household and health behavior has meaningful influence; in addition, the subjective health condition of one-person households are lower than non-one-person households under controlled health behavior.
