본 연구는 턴키 발주공사의 전면적인 재설계 과정에서 원가절감과 사용자 중심의 요구조건을 충족 시킬 수 있는 여러 방법들 중에서 설계 VE(Value Engineering: 가치공학) 프로세스를 적용한 연구이다. 본 연구에서는 설계 VE 프로세스를 사용하여 합리적이고 실용적인 기능분석 프로세스를 단계별로 정립하였다. 설계 VE가 가지고 있는 문제점으로 프로젝트 시행 시기별 적용 프로세스를 계획단계에서 분석할 수 없는 한계점이 있었으며, 또한 대형프로젝트 수행 과정에 초기분석 및 검증을 할 수 없었다. 본 연구에서는 컴퓨터 시뮬레이션 기법을 도입하여 설계 VE가 가지고 있는 문제점을 보완하고, 효율성과 안전성 등을 증명하였다. 기존에 적용해 온 VE기법은 항만시설물 건설에 적용시 시공분야에만 국한하여 적용됨으로써 기능 및 건설비 절감에는 기여하지 못한 것으로 나타났다. 그러나 본 연구에서 제안한 VE 대상선정 방법에 의하여 기능분석 프로세스를 합리적이고 실용적으로 개선함으로써 재설계 VE 수행절차를 효율적으로 개선 할 수 있었다. 본 연구에서 최적화시킨 VE 기법을 항만시설공사에 실제 적용시킨 결과 약 46억 원의 공사비를 절감하는 효과를 거두었다. 따라서 본 연구 결과를 유사프로젝트에 적용 할 경우 VE를 효과적으로 달성 할 수 있을 것으로 사료된다.

This study details the history and characteristics of consumption values, text style analyses, and appeal types expressed in magazine commercials from 1955 to 2008. This study analyzes the level of the social structure of commercial expression for each period. Consumption values based on the categories of consumption values by Sheth (1991) were classified through a total commercials analysis. Analyses on closing types of sentences, types of sentences, and rhetorical figures were executed focusing on headline text and text style. Appealing types were composed of rational, emotional, and ethical appeals. For analysis, the crosstab analysis and chi-square test of SPSS are used. The results are as follow. Seven values were constructed, functional value, social value, emotional value, conditional value, epistemic value, fashionable value, and indistinct value. The ratio of emotional value was the highest and functional value, epistemic value conditional value, fashionable value, social value, and indistinct value followed. The emotional value social value, conditional value, fashionable value, and epistemic value that focused on the emotion of consumers increased, while the functional value decreased. Sentences that use narrative styles, hyperboles, and metaphors that increased the interest of readers were dominantly used in the headline texts. For sentence expression, a declarative sentence in a sentence type, exciting curiosity in the expression method where hyperbole and figures of speech in rhetorical expressions are used most often. Emotional appeal was used almost twice more than the reasonable appeal for appeal types of the total commercial. The lower level of reasonable appeal is information that provides the product function. Interest and expression (such as pleasure and achievement) were used most often for emotional appeal. These results show that the most important issue is the emotional value in consumption in understanding the consumer. Marketing managers should also be aware of the functional value as well as an emotional value.

In urban space, public space is publicly or privately owned space freely accessible by the public. Privately owned public space to the public hosts small-scale rest facilities to serve the public in buildings of certain purposes and sizes for the sake of pleasant urban environment. The Building Act and building ordinances formulate a set of criteria for management and easement of construction standards as well as the area. When creating privately owned public space, one can get incentives through the easement of floor space index and height limit. The purposes of this study were to investigate and analyze privately owned public open space, which is freely accessible by the public, and its adjacent streets and to propose plans to improve the regulations for securing privately owned public space for more rational and practical legal applications. The study then proposed some plans to help to increase the quality of privately owned public space including applying the coefficient to suggest the type of privately owned public space fit for the features of the streets and measure the appropriate utility level differently and distinguishing the mandatory items according to the facility regulations in privately owned public space from the ones qualified for additional points in case of installation. The types of privately owned public open space should be applied differently and the content of facilities intended should be different according to whether it will serve as a resting place or grant more importance on traffic by walking, depending on the features of its adjacent streets. The privately owned public space, the frontage space of building, and the adjacent sidewalks should become a whole and be regarded as one space from the integrated perspective. The results of the study claim further significance in that it investigated privately owned open space and roadside across Seoul. They will serve as useful data to solve the problems with the privately owned public space of the city, which destroys spatial continuity by focusing on the quantitative increase of privately owned open space and creating individual privately owned open spaces and builds high-rise buildings alienated from the existing spaces, and to increase the quality of future privately owned public space.

This study focuses on the factors that make the financial structure of hospitals in Korea different, and on recommended courses of action that could be very helpful to hospitals in maintaining a sound financial structure. Data used in this study were collected from 132 hospitals with complete general data of present conditions as well as financial statements. They were chosen from the 174 hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1996 to 2000 for the purpose of accrediting training hospitals. The dependent variable in this study is financial structure. It consists of liabilities as against total assets (total liabilities to total assets, short-term liabilities to total assets, long-term liabilities to total assets, short-term borrowings to total assets, long-term borrowings to total assets). The independent variables are ownership type, hospital type, location, whether or not a representative is a director of the hospital, the possibility of changing a hospital director, bed size, period of establishment, asset structure, profitability, growth, tax shields, business risk, competition. The factors that appear to have the strongest impact on the liabilities to total assets of all the hospitals sampled are ownership type, hospital type, profitability, tax shields, and business risk. It was found that not-for-profit private hospitals and for-profit private hospitals have more liabilities than public hospitals, and tertiary medical institutions have less liabilities than the secondary general hospitals. Moreover, hospitals earning more at the expense of high business risk have a distinct tendency to lower liabilities. Concerning the current ratio, it was found that factors such as ownership type, hospital type, period of establishment, asset structure, and business risk are the more significant variables. The current ratio of public hospitals is higher than that of both not-for-profit private hospitals and for-profit private hospitals, and the current ratio of tertiary medical institutions is higher than that of general hospitals. As business risk is higher in hospitals compared to other businesses, the current ratio becomes higher; this is because it is assumed that for fear of bankruptcy, hospitals lessen liabilities to total assets. On the other hand, as hospitals become older, the fixed assets to total assets become lower. It is remarkable that in hospitals, the factors affecting liabilities to total assets have an opposite regression coefficient sign against factors affecting current ratio. It brings out the same results borne out by the old financial theories and researches, in which a lot of the liabilities of hospitals are considered as the cause of worsening liquidity. Therefore, it is very important for hospitals to maintain a sound financial structure in order to survive using the rational acquisition and maintenance of capital.

Background: From January 2018, a policy was applied to differentially apply the co-payment for medical expenses of 15,000 won or more from 30% to 10%-30% for each medical fee. This policy lowers the burden on the medical use of the elderly, and it is necessary to analyze the effect of the policy by confirming changes in medical use and supply behavior after 2 years. Methods: The National Health Insurance Service's national medical use database was used. As for the analysis method, first, the medical use and medical supply behavior change over the age of 65 years were confirmed, and second, in order to check the net effect of the policy, the 66-year-old as the experimental group and the 63-year-old as the control group were selected as the control group. The propensity score matching was performed using the variables of age, living alone, income quartile, residence, disability, chronic disease, and co-morbid disease scores, and then it was analyzed using the difference in difference analysis method. Results: The share of the number of treatments under 15,000 won decreased from 37.0% in 2017 to 20.2% in 2018, while the share of the number of treatments under 15,001-20,000 won increased from 8.0% to 22.7%. It was confirmed that the reason for the increase in the cost of treatment per treatment was the result of the increase in the amount of physical therapy and examination. As a result of the policy effect, the burden of co-payment per person was reduced, and as a result, the number of hospital visits per person and the total medical cost per person increased. Conclusion: The self-pay rate differential policy reduced the burden of medical expenses for the elderly and confirmed the increase in medical use. However, the interpretation of the increase in medical use was not able to distinguish whether the unsatisfactory medical care was satisfied or the inducement demand. Efficient allocation of resources is a more important point in the future when the super-aged society is in front. It is necessary to prepare a plan to induce rational medical use within a range that does not impair the medical accessibility of the elderly.

The purpose of this study is to find out problems through looking into the actual condition of management and the extent of application in cooking practice in High School Home Economics Education, and as a practical subject, to present some basic materials to contribute to accomplishing the object of High School Home Economics Education through trying to find a direction to enhance educational value. The contents of this study are these ： to study with a theoretical background character, object, and contents of Home Economics referring to related books and to investigate the actual condition of management, the extent of application to life of cooking practice unit, and standard of recognition of students and teachers about this subject and to find out rational and efficient method of management. 552 girl students and 72 home economics teachers in cities and counties in Kangwon-do were asked to answer the answer-sheet prepared. The result of this study is summerized as follows. 1. Most of the respondent regard the characters and objects of Home Economics as a matter of basic education, education for life, and education for the wholeman, but they neglect the aspect of education for a course of this subject. 2. Among the contents of Home Economics, students are much interested in the Unit of preparing table, especially in cooking. Most of the teachers teach the cooking unit with only explanation without practice because of the lack of material and human resources. 3. Students have desire to do cooking practice, but the extent of application of their real life appears to be low. 4. It appears to be necessary that boy students as well as girl students should learn Home Economics as an education for preparation for managing housework. 5. Home Economics teachers are mostly satisfied with their teaching profession. But teachers who have been teaching for 3 or 5 years appear not to be satisfied with it. 6. Although Home Economics teachers can teach Cooking practice Unit with confidence, they usually do it with theory rater than with practice, and they evaluate it after practicing, but most of them do not add the result to the student’s grade. 7. They use most of the cookers fixed on the standard list of High School Cooking Practice appliances, but they seldom use electric heating cookers.

KOMPSAT-2(KOrean MultiPurpose SATellite-2)위성은 GSD(Ground sample distance) 1m급 전정색(panchromatic) 영상과 GSD 4m급의 다중분광(multispectral)영상을 동시에 제공하는 세계 7번째 고해상도(High-Resolution) 위성으로 지도제작, 국토모니터링, 환경 등 여러 분야에서의 다양한 활용이 기대된다. 그러나, KOMPSAT-2영상은 다중분광센서(MSC : Multi Spectral Camera)의 복잡성과 보안성에 의해 위성궤도 및 자세정보 등 영상 취득 시 기하학적 정보 및 영상이 제한적으로 제공되고 있어 KOMPSAT-2 영상을 이용한 다양한 연구가 미흡한 실정이다. 이에 본 연구에서는 KOMPSAT-2의 스테레오 영상을 이용하여 DEM 및 정사영상 제작실험을 수행하여 KOMPSAT-2 영상을 이용한 지형공간정보 생성 가능성을 타진하고자 하였다. KOMPSAT-2영상을 이용한 DEM(Digital Elevation Model) 및 정사영상을 제작하기 위해서는 먼저 표정해석(orientation)을 수행하여야 한다. DEM을 제작하여 정확도를 분석한 결과, 전반적으로 수치지도에 비해 표고가 높게 추출되었다. 평지부에서는 평균 1.8m, 구릉지에서는 평균 7.2m, 산지에서는 평균 11.9m의 표고오차를 나타냈다. 본 연구를 통해 생성된 정사영상의 수평위치오차 평균은 ${\pm}3.081m$로 1:5,000 수치지도 수평위치오차 허용범위인 ${\pm}3.5m$ 준하는 것으로 나타났다. KOMPSAT-2호 영상을 이용하여 DEM 및 정사영상을 제작한 결과, 1:5,000급의 수치지도제작 및 지형공간정보 생성에 활용할 수 있을 것으로 판단된다.
