건설 산업의 속성상 프로젝트의 성과를 정량적으로 분석하기 위해서는 다양한 영향인자에 대한 고려가 필수적이다. 프로젝트의 특성과 성과와의 관계를 파악하고, 프로젝트에 가장 적합한 관리기법을 적용시켜서 프로젝트의 성과를 향상시키기 위해서는 성과관련 정보를 축적시켜 관리하기 위한 시스템적인 접근이 요구되고 있다. 그럼에도 불구하고 많은 성과관련 시스템들은 성과결과의 분석에만 치중하여 프로젝트의 특성이나 관리기법 등 성과에 영향을 미치는 인자에 대한 심도 있는 분석방법과 접근방식에 대한 고려 부족으로 인해 성과시스템의 활발한 적용을 기대할수 없었다. 이에 본 연구는 건설 프로젝트의 특성을 고려하여 성과를 사전에 예측하고 성과체계를 정량적으로 모델링할수 있는 성과정보시스템을 개발하는 데 목적을 두었다. 이를 위해 실제 사례프로젝트의 성과관련 정보를 바탕으로 성과결과와 프로젝트 특성, 관리기법 간의 상관관계를 분석함으로써 해당 프로젝트에 가장 적합한 관리기법을 도출할수 있는 방안을 수립하였다. 그 결과, 성과영역별로 다양한 관점에서 프로젝트의 성과비교가 가능할 수 있는 정량화 방안을 정립하였고, 상관관계 분석을 통해 성과예측이 가능한 모델을 제안하였으며, 기존 데이터 분석을 통해 최적 관리기법을 선정할수 있는 시스템을 개발하였다. 웹기반 프로그램으로 구축된 시스템은 향후 데이터베이스의 지속한 관리와 보완을 통해서 성과정보의 양을 확대시킨다면 통계적으로 유의미한 결과를 바탕으로 신뢰성 있는 프로젝트 성과 관리를 도모할수 있을 것으로 사료된다.

Objectives: The purpose of the study is to evaluate the contents analysis of the community dental hygiene practice in the dental hygiene students and suggest the outcome based evaluation index of community dental hygiene practice. This study will provide the basic data for the community nursing and social welfare practice. Methods: A self-reported questionnaire was completed by 82 dental hygiene professors and 254 dental hygienists in community health centers after receiving informed consent based on institutional review board from 5th Dec 2014 to 30th Jul 2015. A total of 49 professors and 134 dental hygienists gave the complete answers. The study instrument was adapted from the literature review. The questionnaire consisted of evaluation, purpose of evaluation, and evaluation format. Data were analyzed using SPSS 20.0 program. The contents analysis was carried out through input, process, output, and outcome. Results: The practice outcome evaluation was conducted in 62.9% of the dental hygiene departments and 32.9% of the community health centers. Most of the dental hygiene professors chose "To know what students learned(27.3%)" and "To ensure student's role and behavior in practice(27.3%)." as the purpose of evaluation. The public dental hygienists chose "To score the practice grade(42.1%)." The evaluation method was done anonymously. Conclusions: The outcome based evaluation in community dental hygiene practice was the best method to evaluate the practice education for the competency of the dental hygiene students.

Purpose : The purpose of this study is to check the current status of accessability to rehabilitation therapy in local areas and to review how to improve the accessability. In fact, first, it is very hard for patients to find out a local medical center with rehabilitation therapy capability. Moreover they needs to wait long time to get a treatment they need, because of lack of nearby rehabilitation centers. The best way to enhance the accessability to the rehabilitation therapy service is to allow therapists to set up rehabilitation centers in local areas on their own, physically independent from medical doctors. Basically, the current law does not prohibit therapists' own sole practice. However, it needs to be amended by inserting an explicit legal basis on the setting-up process. If it is legally permissible for the therapists to set up rehabilitation centers to perform a rehabilitation treatment with referrals from of medical doctors (though physically independent from the doctors), it would result in the increase of profits for the doctors and at the same time raise therapists' freedom of occupation, a constitutional right. Furthermore, with their own places to practice, therapists will have to compete with other therapists, that would raise the quality of their treatments, which will in turn benefit patients ultimately. A proposed bill of amendments to the Act on Medical Technicians and etc. is pending for review at the National Assembly. I look forward to vigorous discussion on the bill based on this article, and resulting in revision of the law for the benefits of patients.

Objectives : The purpose of this study was to examine the oral health awareness and practice of workers. Methods : The subjects in this study were 200 workers in a working place located in Taean-gun, Chung-Nam Province. The data for this study was obtained by means of a self-administered questionnaire. Results : 1. An average of awareness for the oral health of workers was $2.60{\pm}0.44$ points out of 4. They were most aware of the item that toothbrushing should be done after meals($3.06{\pm}0.42$), and the second most widely recognized item was that toothbrushing should be done before bedtime($2.73{\pm}0.60$). 2. An average of practice for the oral health of workers was $2.54{\pm}0.32$ points out of 4. They did the best was brushing their teeth after meals($2.97{\pm}0.33$), followed by cleaning the tongue during toothbrushing($2.91{\pm}0.45$). 3. Awareness of oral health was significantly higher in such groups, including the female, college graduates, unmarried(p<0.05). 4. Practice of oral health was significantly higher in such groups, including the female, college graduates(p<0.05). Conclusions : To reform and improve of the system, incremental oral health care system for workers is needed. and oral health education is needed to increase the motivation of workers to control their basic dental disease.

The aim of this study was to identify the most effective methods with which to revitalize Korean high school culinary education. To achieve this aim, a culinary recognition questionnaire survey of 616 students from 9 culinary high schools was carried out. The 9 surveyed schools represented the following of 7 regions: Chungnam, Busan, Incheon, Daegue, Jeonbuk, Gyeongbuk, and Gwangju. Collected data were subjected to descriptive analysis, $x^2$-test, t-test, and one-way ANOVA using SPSS(version 14.0). The results of this study are as follows. Culinary practice interest and learning demand of most students were high. 6.8% of students indicated that initial theory learning, followed by video education, and finally live demonstration is an effective teaching methodology. They preferred practicing on actual ingredients as the primary teaching and learning method, nominating technician cooking as the most favorite. As for areas needing improvement in culinary practice education, difficulties with material preparation and insufficient learning hours were identified as prominent factors by 66.8% of respondents. There was unanimous agreement that culinary practice education can be enhanced by highly skilled teachers, while interest for the discipline itself can be fostered by initiating and encouraging cooking participation in the home. Freshmen and special high school students suggested that a cooking related website is necessary to expand the current information interface, which is currently limited to colleagues and employers. In relation to culinary education revitalization, consistent promotion of departments, or high schools that have proven student satisfaction rates and effective culinary curriculum are required. Furthermore, teachers can also aid this process by more effective student pastoral care in order to improve school life satisfaction. However, teacher job satisfaction is an important component of this process, and better employment conditions and remuneration packages reflecting extra work must be considered as part of an attractive teacher-incentive employment policy.

Among different regression approaches, nonparametric procedures perform well under different conditions. In practice it is very hard to identify which is the best procedure for the data at hand, thus model combination is of practical importance. In this paper, we focus on one dimensional regression with fixed design. Polynomial regression, local regression, and smoothing spline are considered. The data are split into two parts, one part is used for estimation and the other part is used for prediction. Prediction performances are used to assign weights to different regression procedures. Simulation results show that the combined estimator performs better or similarly compared with the estimator chosen by cross validation. The combined estimator generates a similar risk to the best candidate procedure for the data.

In this study the spatial distribution characters of burnt forest site was first considered by analyzing spatial data and monitoring forest landscape before/after lire to restore the site. Then suitable tree species on each forest site should be selected through the weighted score analysis of GIS analysis methods. Finally. the best forest stand arrangement method could be simulated on the system for the advanced reforestation technology in Korea. For this purpose, the virtual reforestation system was implemented by using the concept of virtual GIS and CBD (Component Based Development) method. By use of this system the change of forest landscape of burnt forest area some years after reforestation practice could be detected and monitored by applying the site index and 3D modeling method.

The first-best pricing rule which achieves economic efficiency is to equate price with marginal cost. Since public transport demand is derived from some other demand, the user cost as well as the producer cost are considered in its pricing. The optimal price is derived from a derivative of the total social cost with respect to demand. In case of the bus, if there is enough capacity for demand increase, the optimal price is determined by the marginal producer cost resulting from bus sped decrease and by the marginal user cost resulting from journey time increase. Both are caused by boarding and fare collecting time of an additional passenger. Because of the budget constraints, the marginal cost pricing cannot be applied in practice. Then price discrimination as the second-best pricing is introduced. The Ramsey pricing, to charge different prices for different demand elasticities, and nonuniform prices such as travelcards can be applied. However, there is practical difficulty in implementing these prices because of great informational requirements, the costs of administration and the ease to users.
