설계도면을 중심으로 산출되는 물량정보는 건설 프로젝트 생애주기 동안에 프로젝트 참여주체들에게 비용과 관련한 의사결정에 결정적인 역할을 하는 매우 중요한 정보이다. 이러한 정보를 생성하는 물량산출 업무가 수작업에 많이 의존하다보니 작업자의 실수에 의한 오류가 빈번하게 발생하고, 견적담당자의 노하우에 따라 물량의 차이가 존재하기도 한다. 또한, 설계변경에 의해서 물량산출을 위한 재작업에 들어가게 될 경우 모든 물량산출 프로세스를 다시 거쳐야 하는 문제가 있다. 이러한 제반 문제는 견적자동화를 통해 물량산출의 정확성 확보 및 설계변경 시 요구되는 물량산출의 대응력에 대한 요구를 증대시키고 있으며, 최근 3D CAD Modeler에서 생성된 3D CAD 모델을 기반으로 견적업무프로세스를 자동화하려는 연구가 다양한 관점에서 시도되고 있다. 그러나 기존 연구에서는 특정 3D CAD Modeler를 중심으로 한 견적자동화에 대한 연구로 다양한 3D CAD Modeler에서 생성된 3D CAD 모델로부터 물량정보를 취득하기 위한 공통체계 구축하고 이를 기반으로 BIM기반 견적자동화를 이루는 데 한계를 가지고 있다. 따라서 본 연구에서는 이러한 BIM기반 견적자동화 체계구축을 위한 기반 연구로 다양한 3D CAD Modeler로부터 물량산출을 자동화하기 위해 Modeler가 내부적으로 가지고 있는 Quantity Data Type을 추출하고, 이를 분석 및 검증할 수 있는 체계를 개발하였다.

To look at Korea trade environment, as increasing the quantity of goods transported in North-East Asia and deepening national competitive, information-oriented logistics environment is needed. That means it is automated work process and can provide value-added service. To do this, logistics business can be efficiently handled through "Electronic Means for the Clearance of Ships" and electronically data processing. Also, by increasing the risk of international terrorism, regulation regarding to logistics security has strengthened around the advanced country, such as USA and EU, etc. or international organization, such as IMO, ISO, etc.. Furthermore, because trade and logistics environment is changing and security becomes more important in logistics area, movement or status information of goods within the port or in entry in/out becomes more and more be needed in real time. In case cross-border logistics activities, international cooperation or agreement between countries is very important. However, different opinions much happened on defining the interface. If to follow one format or type using at a specific country or organization, it was occurred to difficulty in respect of interoperability as well as additional costs or time. Therefore, this paper proposes common interface model to exchange information for the efficient global SCM for using by the output of Korea R&D project, "National Logistics Standardization System Development".

Rising healthcare cost is a global phenomenon that justifies governments' introduction of 'incentive regulation' plan for the improvement of hospital efficiency. A number of previous studies tried to evaluate the efficiency of healthcare organization by using Data Envelopment Analysis(DEA), a common efficiency benchmarking method. However, there is a concern that this kind of efficiency evaluation could induce "quantity-quality trade-off". Moreover, as quality aspect is especially important in terms of 'effectiveness' of health care, it should be considered in efficiency evaluation of healthcare organization. A number of different models were tried so far to incorporate quality aspect into DEA, however, none is universally recognized as a standard. Thus, in this study, previous quality-incorporating DEA models were categorized into 6 types according to the way of incorporating quality aspect, and strengths and limitations of each type were reviewed with a set of artificial data as an example. Based on this review, a new quality-incorporating efficiency evaluation model, named Quality-adjusted output DEA(QAO-DEA), was suggested. As an exploratory empirical analysis, technical efficiency of human resource were measured with different quality-incorporating DEA models, using 2004 data from National University Hospitals. In conclusion, Quality-adjusted output DEA(QAO-DEA) model seems to be one of the most desirable alternatives to incorporate quality aspect in efficiency evaluation of hospital, and deserves the consideration as a policy tool to induce simultaneous improvement of both efficiency and quality.

This study investigated the annual frequency and clothing type by extracting puff sleeves designs from overseas fashion collections from S/S and F/W 2017 to S/S and F/W 2019. Specifically, it analyzed production characteristics and pattern methods by the type of puff sleeve design, and found the following: In terms of the percentage of puff sleeves by season, S/S 2019 was the highest. Since Newtro, with a 1990s sensitivity, was the mainstream trend during the S/S 2019, power puff sleeves, a signature of the Newtro style, accounted for the greatest portion of this design feature. In terms of the type of clothes with puff sleeves, 'dress' (54.3%) was the highest, followed by 'shirts/blouse' (27.5%), 'jacket/coat' (12.5%), and 'padded coat/jacket' (5.7%). Specifically, puff sleeve patterns were found mostly in the 'dress' category, more than 47% every season, while the figures were more than 23%, 9.3%, and 2.6% in 'shirts/blouse', 'jacket/coat' and 'padded coat/jacket', respectively. In other words, puff sleeve designs were more common in 'dress' or 'shirts/blouse' than in a 'padded coat/jacket'. In general, the shoulder length is reduced to prevent the shoulders from looking broader because of puffs. In contrast, recent puff-sleeve styles differ from those introduced by modern fashion designers in that they have drop shoulders with puffs attached. Furthermore, as constructive and over-exaggerated sleeve patterns appeared, puffs were applied to diverse sleeve styles including mutton leg and Mameluke styles. The analysis results of this study will contribute to the development of the fashion industry through small quantity batch production pursuing unique styles and serve as the basis for further studies on the configuration methods of puff sleeves. This study will be used in various ways, including as educational material on sleeve patterns. Through the analysis of sleeve patterns, this study tries to provide basic data for planning the design of puff sleeves and helping to diversify the ladies' apparel market in the future.

The purpose of this thesis is to offer basic data for clothing design which is intended to apply appropriate shape and capacity to clothes. The following are the analyzed results of an investigation which was conducted to characterize the upper half of the female body of 193 women whose ages are 18 to 25, taking part in this investigation. According to the results of analyzing young women's bust, I came to find a large individual difference of the wide varying factor numbers at the items of the side feature, the body stance, and the dart quantity. For the analysis of the female's upper body, 11 factors are used. The are as follows: Factor 1. width of the bust Factor 2. height of the bust and length of the arm Factor 3. side thickness of the bust and the upside type Factor 4. length of the bust on the front Factor 5. length of the bust on the back Factor 6. salient ratio of the breast Factor 7. width of the neck. the armhole, and measurement of the droop Factor 8. length of the shoulder Factor 9. flat ratio of the bust Factor 10. inclination of the shoulder factor 11. form of the back The shape of young women's upper bodies can be divided into four groups. The character ization of each group are as follows : Group 1 . 28.5% of the women who take part in this investigation belong to Group 1 These women have the shortest body, with a longer length of the front than the back and more thickness on the front than the back. Group 2. 21.1% of the women who take part in this investigation belong to this group. They show a longer length of the back and more thickness of the back than the front. In addition, this group is bent forward. Group 3. This group is the mast common type, showing the shortest and thickest character. 37.8% of the women who take part in this investigation have this bust character Group 4. 12.4% of the women belong to Group 4. They possess the highest and fattest character, skewing smaller necks, armholes, and waists than the other groups. This group also shows the drooping shoulders.

Breast cancer is the most common cancer among women worldwide. The primary aim of this work was to provide an in-depth evaluation of research publications in the field of diets and breast cancer. The impact of economic outcome on national academic productivity was also investigated. Data were retrieved using Pubmed for English-language publications. The search included all research for which articles included words relating to "diets and breast cancer". Population and national income data were obtained from publicly available databases. Impact factors for journals were obtained from Journal Citation Reports$^{(R)}$ (Thomson Scientific). There were 2,396 publications from 60 countries in 384 journals with an impact factor. Among them, 1,652 (68.94%) publications were Original articles. The United States had the highest quantity (51% of total) and highest of mean impact factor (8.852) for publication. Sweden had the highest productivity of publication when adjusted for number of population (6 publications per million population). Publications from the Asian nation increased from 5.3% in 2006 to 14.6% in 2012. The Original article type was also associated with geography (p<0.001; OR=2.183; 95%CI=1.526-3.123), Asian countries produced more proportion of Original articles (82%) than those of rest of the world (67.6%). Diets and breast cancer-associated research output continues to increase annually worldwide including publications from Asian countries. Although the United States produced the most publications, European nations per capita were higher in publication output.

Purpose: Donor site seroma is the most common complication of extended latissimus dorsi flap for breast reconstruction. One of preventive treatments is to use the fibrin sealant in donor site before closure. Experimentally, it has been used successfully in the prevention of latissimus donor site seroma, but its clinical efficacy and results were very controversial. Thus, the purpose of this study is to evaluate the clinical efficacy and to determine the optimal dose of fibrin sealant. Methods: A retrospective study was done of patients operated under same surgical conditions by one operator with variable doses of fibrin sealant. The study group consisted of 60 consecutive patients who underwent breast reconstruction with extended latissimus flap reconstructions from January 2005 to December 2006. Patients were divided into 4 group by applied fibrin sealant amount(group 1=0 mL, group 2=1 mL, group 3=2 mL, group 4=4 mL). Retrospective data were obtained from total postoperative drainage amount, time from surgery to drain removal, and incidence and quantity of seroma formation in matched patients group. Results: Total drainage amount decreased relative to the amount of fibrin sealant. The seroma formation rate of 30% in the study group 4 was significantly less than group 1 rate of 71%(p<0.05). It was an improvement over the rates of as much as 79% described previously in the literature. Also, time from surgery to drain removal was shortened significantly in group 4 patients(p<0.05). Conclusion: The use of fibrin sealant in the extended latissimus dorsi flap donor site appears effective in preventing seroma. However, important factors to obtain lower seroma formation rates are proper techniques and proper amounts such as the authors suggested amount: $0.01mL/cm^2$ with spray type fibrin sealant.
