정부는 노후불량주거지에 대한 개선책으로 "도시 및 주거환경정비법"을 통한 주거지정비사업을 시행하고 있다. 하지만, 최근 경제성장 하락을 포함한 다양한 요소가 복합적으로 작용하여 정비사업 추진은 난항을 겪고 있다. 정비사업의 추진실적이 저조함에 따라, 그 원인을 규명하여 사업의 추진성을 향상시키고자 다양한 연구가 진행되어 왔다. 이러한 연구의 동향에서, 본 연구는 부산시를 대상으로 토지 및 건축물특성에 따른 정비사업 추진 분석을 진행하였다. 분석 간 종속변수는 "도시 및 주거환경정비법"에서 명시하는 바와 같이, 추진단계를 종합적 단계적으로 구성하였다. 그리고 정비(예정)구역 지정 시 기준이 되는 토지 및 건축물특성을 독립변수로 설정하였다. 순서형로짓모형을 통해 이를 분석하였으며, 지형적 여건, 조합원 수와 관련된 요인, 분양가에 영향을 미치는 요인, 입지적 여건이 사업 추진에 유의미한 영향을 미치는 것으로 추정되었다. 분석결과를 종합하면, 다수의 요인이 사업의 경제성과 연관되어있음을 알 수 있다. 노후불량주거지에 대한 도시계획사업의 일환으로 진행되는 주거지정비사업은 공공성이 요구되는 사업인 만큼, 단순 사업의 경제성과 연관된 요인에 편중되기보다 해당 정비구역의 주거환경을 고려하여 정비 시급성에 의한 사업추진이 필요해 보인다. 이에 따라, 신속하고 합리적인 사업 추진을 당부하는 바이며, 사업추진 지연에 따른 행정적 경제적 손실 등을 미연에 방지해야 할 것이다.

Service Providers need to monitor the level of consumer's satisfaction on service they provide continuously and they use appropriate method to measure their operating status. They have to make a plan on their resource and infrastructure to provide their service in the right place at the right time whenever they need. Most previous studies on IT service quality are mainly focused on criteria or levels of quality measurement even though those criteria and levels should be set by considering consumer's needs. And considering for consumer's needs with managerial factors was not found on those studies. So, we suggest deducing quality factors for continuous improvement of IT service management system in this paper as identify the relative priority using QFD method which consider consumers' voices and managerial factors when decide quality factors of IT service management system introduced SLA. We also confirm that our suggestion is practicable and applicable for current operation by case study.

Purpose: First, this paper suggests an alternative approach to find optimal portfolio (stocks, bonds and ESG stocks) under the maximizing utility of investors. Second, we include ESG stocks in our optimal portfolio, and compare improvement of welfares in the case with and without ESG stocks in portfolio. Methods: Our main method of analysis follows Brennan et al(2002), designed under the continuous time framework. We assume that the dynamics of stock price follow the Geometric Brownian Motion (GBM) while the short rate have the Vasicek model. For the utility function of investors, we use the Power Utility Function, which commonly used in financial studies. The optimal portfolio and welfares are derived in the partial equilibrium. The parameters are estimated by using Kalman filter and ordinary least square method. Results: During the overall analysis period, the portfolio including ESG, did not show clear welfare improvement. In 2017, it has slightly exceeded this benchmark 1, showing the possibility of improvement, but the ESG stocks we selected have not strongly shown statistically significant welfare improvement results. This paper showed that the factors affecting optimal asset allocation and welfare improvement were different each other. We also found that the proportion of optimal asset allocation was affected by factors such as asset return, volatility, and inverse correlation between stocks and bonds, similar to traditional financial theory. Conclusion: The portfolio with ESG investment did not show significant results in welfare improvement is due to that 1) the KRX ESG Leaders 150 selected in our study is an index based on ESG integrated scores, which are designed to affect stability rather than profitability. And 2) Korea has a short history of ESG investment. During the limited analysis period, the performance of stock-related assets was inferior to bond assets at the time of the interest rate drop.

Purpose: The purpose of this study is to identify key performance evaluation items and factors that are effective and practical for project management of defense standard standard improvement projects, and to develop a quantitative performance evaluation model. Methods: For the development of a performance evaluation model for defense standard improvement projects, we analyzed past major project performance and derived evaluation items and factors. To increase the objectivity and efficiency of project evaluation, we developed an evaluation index that enables relative evaluation of evaluation targets, and calculated the main importance of evaluation items using the Analytic Hierarchy Process (AHP) method based on the main opinions of expert groups. Results: The study resulted in the identification of main performance items for defense standard improvement projects, which were classified into defense standard conformity review performance and defense standard improvement performance items. We also simplified the evaluation model by integrating various evaluation items into similar evaluation factors. Additionally, we developed a quantitative evaluation index that enables relative evaluation of the targets and verified the objectivity and validity of the suggested performance evaluation model by reevaluating it using performance data from past commissioned professional institutions Conclusion: Developing a quantitative evaluation model for defense standard improvement projects is expected to provide a means of measuring the effectiveness of the project, and to be used as a tool to determine the appropriateness and effectiveness of medium and long-term project plans.

Objective : In Modern society, patients with facial nerve paralysis are increasing because of many factors - irregular life, cold, overwork and stress etc. We have troubles in presuming the prognosis, though how to diagnosis and examine facial nerve paralysis are many. Methods : A clinical study was done on 89 patients who were diagnosed and treated as facial nerve paralysis(Bell's palsy) from January 2001 to May 2003 at the Dep. of Acupuncture and Moxibustion, college of Oriental Medicine, Woo-suk University. We classified 89 patients as the Sasang(四象) constitution, contributing factor, season, age and existence of diabetes items and analyzed, as we would research differences of changing point-Period from on set of Bell's palsy to the day which the change begins to be seen at the face- and improvement -Period which Bell's palsy is improved from on set to H-B grade II. Results : 1. Among the Sasang constitution, Soeumin($10.67{\pm}3.77days$) were faster than other constitutions, but Soyangin($16.25{\pm}6.75days$) were slower than other constitutions in changing point. Taeumin($4.12{\pm}1.49weeks$) were shorter than other constitutions, but Soyangin($4.88{\pm}2.11weeks$) were longer than other constitutions in improvement. 2. Among contributing factors, overwork and stress group were slower than other contributing factors in changing point($13.95{\pm}6.52days$), and longer than others in improvement($4.67{\pm}1.87weeks$). 3. Changing point and improvement of season, age, and existence of diabetes had the difference of the average according to an each item, but they were not statistically significant. 4. In 89 patients with Bell's palsy, average changing-point was $13.11{\pm}5.99$(days) and average improvement was $4.47{\pm}1.82$(weeks). Their correlation was 0.687 and statistically significance(P<0.01), therefore we could decide that their relation is highly correlation.

The cafeteria is one of the welfare facilities in the college and crowed with students during lunchtime because of the various menu, saying time and cheap price. In designing the cafeteria, we have to consider the users' needs and the factors which effect on their satisfaction and behavior under the pleasant environment. The purpose of this study is to draw the environmental improvement factors by Post Occupancy Evaluation. A survey about the users' actual condition and environmental satisfaction level and a behavior observation in the field were utilized as the study methode. The 150 copies of questionnaire were completed by students who ate at the cafeteria of W college in Daejeon city. The SPSS 15.0 for Windows was used for a statistical analysis. The results are listed below; two factors were drawn as the improvement elements through the combination of the unsatisfactory items obtained by the descriptive statistics and the influential items by the multi-regression analysis. They are images and approach. In the 'image' category, there us a statistical difference between the present image and prefer image. The users prefer much brighter, warmer, newer, more gorgeous, more cheerful, more clear, more active, more comfortable, and more modern image of cafeteria. In the 'approach', the location of ail existing cafeteria is inaccessible from the classrooms in spite of an important relationship between classrooms and cafeteria. Therefore the complementary plan for convenient approach is demanded for improvement of users' satisfaction.

Although many people initially enroll in health education programs, there are many instances of erratic participation and dropouts. Inconsistent participation in intervention programs minimizes their impact on health promotion. Therefore, a theoretical understanding of factors influencing participation in these programs can potentially enhance the effectiveness of its educational strategy. This study used the Pender's Health Promotion Model to examine specific factors influencing incentives to participate in an elderly nutrition education program. The Elderly Nutrition Counseling and Education Program was conducted with 147 volunteers (76 males, 71 females), aged 60 to 87, at 5 separate community elderly centers, by public health dietitians from February to April 1997. Some participants dropped out during the program. Overall, 61 people(18 males, 43 females) finished all 7 steps over 2 months. Pre-intervention data were collected by trained dietitians. This data included individual cognitive-perceptual factors(perceived benefits of nutrition improvement, importance of health, perceived control over health by multidimensional health locus of control, self esteem, perceived health status, concern about health, depression scale and social health scale), which were known to influence the likelihood of health behavior, and modifying factors(socioeconomic variables, biological characteristics, behavioral factors, such as smoking, alcohol drinking and exercise). Male finalists had a significantly lower chance for health locus of control, and better social health status with their children and grandchildren, compared to males who dropped out. Female finalists had a significantly higher locus of control regarding food behavior, higher self-esteem, better recognized nutritional status, worse self-recognized health status and lower concern about health than those who dropped out. There was no significant difference between the attendees and dropouts in age, BMI$(kg/m^2)$, Nutritional Risk Index, depression scale and daily nutrient intake. These results suggest that elderly nutrition intervention plans should focus on the individual cognitive and perceptual factors, with interpersonal influences, to increase participation in nutrition in nutrition improvement programs.

As interests in the quality of data in database systems are growing recently, analysis and improvement of data quality in databases have been an important issue. However, there has yet to be a clear agreement on how to reasonably calculate the total cost of such project. In this paper, based on real project data and budget statistics, we develop a model to estimate the cost for quality analysis and improvement project of a database. We first conduct statistical analysis to build our basic model. Throughout this analysis, we have identified factors that determine the scale of works required to conduct the project and eventually determine the cost. In addition, we have identified factors that determine the complexity of the project. These factors can adjusts the cost determined by the scale of works. Our model is verified and improved by surveys on experts. We apply our model to newly conducted projects and observe that our model estimates the cost of each project reasonably well.
