The purpose of this study is to develope an assessment method for parking lot remodeling alternative by adopting the asset management technique. In order to identify the Level of Service(LOS) and the Evaluation Measurement(EM), literatures was implemented which documented the consideration of parking lot plan, needs of the apartments' tenant, and various design standards. In addition, the authors conducted a three-time delphi survey for the identified 5 LOS and 19 EM to evaluate suitability and necessity of them and to collect additional opinion of experts. The LOS of parking lot were categorized into 5 areas such as Environmental effect and Convenience, Accessibility and so on. The 19 EM were determined to estimate the LOS quantitatively. The researchers analyzed the degree of importance of LOS and EM by using the Analytic Hierarchy Process (AHP) method. But construction cost was excepted from the analysis, because it is used as an independent variable in alternative assessment. In conclusion, the authors proposed the estimation criteria for EM, and the method and process for alternative assessment be performed to benefit-cost analysis using the LOS variation and construction cost. The assessment method for parking lot remodeling alternative was demonstrated effective to assess the parking lot remodeling alternative by case-study. This study has a academic significance by adopting the asset management techniques in the area of the parking lot remodeling. And the assessment method is expected to help deciding a reasonable remodeling alternative of parking lot, as it ensures the diversity for remodeling of the parking lot and reflects the needs of the occupant.

Competency means 'the ability to do something', and competency-based education means 'the process of education based on the concept of competency'. Competency-based education is generally implemented in general education. However, competency-based education has not yet been actively conducted in the field of Christian education. In particular, it has not been established academically on what competencies Christian alternative schools provide in common. Most of the previous studies related to competency-based education in Christian education are related to competency-based education conducted by Christian universities. Research related to competency in Christian alternative schools is mainly related to the professionalism of teachers or the ideology of Christian alternative schools. In other words, there are few specific studies on what kind of competency they provide to students attending Christian alternative schools. Therefore, this study aims to understand the reality of competency-based education conducted by Christian alternative schools using Delphi analysis techniques. Through this study, four goals and 20 competency elements of competency education pursued by Christian alternative schools were found. By categorizing the goals and elements of competency education, it can be divided into relationships with God, relationships with oneself, and relationships with others and the world. In conclusion, it was suggested that Christian alternative schools should provide education that pursues the universal purpose of Christian education based on specificity and reflect the goals and elements of competency education in the curriculum.

This study was practiced to compare educational status and recognition of Home Economics curriculum between alternative and general middle school students. The survey was conducted to 130 alternative school students and 241 general school students in Gyeonggi province. In students' satisfaction on their school, there is appeared the highest at 'average'(38.6%) in general schools and 'satisfied'(40.8%) in alternative schools, showing that those in alternative schools have greater satisfaction on their schools(p<0.001). In the degree of recognition on Home Economics curriculum, the perception as an 'important subject' was average of 3.08/5 points in general school and 3.32/5 points in alternative school, indicating that the recognition in alternative schools was higher than general ones(p<0.05). Also, degree of satisfaction on practice and lecture class was higher in alternative than general schools. However, it was found that the use of audiovisual learning material in alternative schools was much smaller than that of general ones, and the former had poor facilities and practice labs. Regarding degrees of interest in Home Economics curriculum, 'average'(36.9%) in general school and 'rather interested in the subject'(38.5%) in alternative schools were most common. About the opinion that they needed to learn Home Economics subject, the answer 'it is needed' was 67.6% in general schools and 79.2% in alternative ones, presenting that the students in alternative schools more felt the need to learn the subject(p<0.05). Regarding the comparison of interest level for each area in Home Economics curriculum according to gender, there was only difference on the area of 'preparation and management for clothing'. On the area, the degree of interest was higher in girls than boys at all the schools(p<0.05). Therefore, in alternative schools, it is suggested that various uses of audiovisual learning materials at teaching and expansion of practice facilities should be provided and created desirable Home Economics class. Also in general schools, it is urgent that countermeasures to increase the practice classes are established in order to improve interest and satisfaction of Home Economics education.

VE is used as a powerful tool to add value to facilities by improving functionality and reducing costs. By identifying the client's requirements in the VE process and reflecting them in the quality model, the developed alternatives meet the client's requirements. However, there is no process to verify how the developed alternatives reflect the needs of the client through functional analysis, idea generation and evaluation. The purpose of this study was to develop, verify, and prove the effectiveness of a methodology for evaluating client satisfaction with alternatives developed during the VE Job Plan. The KANO model, which can identify the satisfaction and dissatisfaction of requirements in product planning, was set as a methodology for alternative verification procedures of VE, and was improved and applied to the purpose of this study. As a result, the alternative evaluation method developed in this study was found to be useful. It is expected that the KANO model will be used to evaluate the satisfaction of VE alternatives in the VE Job Plan analysis.

The purpose of this study was to investigate the alternative models of seasonal changes that preservice secondary teachers presented using the Lakatosian methodology. Participants included 74 undergraduate students who majored in science education within the college of education. Their responses to these questions revealed students' alternative models were inconsistent with scientific models. A great deal of this apparent inconsistency could be explained by assuming that the students used, in a consistent fashion, a alternative core belief on seasonal changes. This study also discussed the core beliefs and the possible sources held by preservice teachers in order to overcome their alternative models. The sources of alternative models may lie in the contents used in textbooks.

This study Presents an guideline of the exclusive bus and/or truck lane on 8 lanes freeways using FREFLO model and INTEGRATiON model. Four alternatives : do nothing, bus exclusive lane, truck exclusive lane, bus and truck exclusive lane, were evaluated using average daily vehicle travel time as measures of effectiveness. It is found that bus and truck exclusive lane is the most effective alternative reducing total travel time by 7% when ADT is below 80,000 vehicle/day. However, when ADT is above 80,000 vehicle/day and bus Proportion is above 12%, bus exclusive lane is the most effective alternative reducing total travel time by more than 5.6%. It is further found that INTEGRATION, the stochastic and microscopic model, is more sensitive than FREFLO, the deterministic and macroscopic model, in evaluating the effectiveness of four alternatives.

Due to the various characteristics of urban river, rehabilitation project for natural river requires distinct alternative approach and selection method for each different types of river. In this study, naturalness of a river was used to establish such alternative for the business and rehabilitation plan for natural river. To assess the naturalness of a river, through AHP, designed to fit the environmental conditions in Korea, was employed. Furthermore, a method that conveniently compares and selects an alternative for rehabilitation plan for natural river by referencing Urban River Basin Enhancement Methods (URBEM) was proposed. After selecting the evaluation items for assessing the naturalness of the river based on the characteristics of the river, multiple alternatives were constructed and the naturalness of river for each of those alternatives were estimated. Comparing the estimated values has made the measurement of the natural recovery effect and the product of river rehabilitation plan for each alternative efficient. In conclusion, selecting the items for evaluating the naturalness of a river with respect to its characteristics was found to be effective for establishing the rehabilitation plan for natural river.

Using a sample from Korea Education Employment Panel(KEEP), this study attempts to ascertain determinants of demand for alternative education in Korea. It found that children's gender and duration of computer use exert a strong effect on demand for alternative education. Also, those parents, who show more interest in government's education policy; are less content with the schools their children are attending; and exhibit the higher likelihood of migration for children's education, appear to have the stronger tendency to seek alternative education for their children. Meanwhile, there was a significant difference between male and female students in the factors that influence demand for alternative education. For male students, duration of computer use and the parents' interest in government's education policy tend to matter. For female students, however, health condition seems to be associated with demand for alternative education. For both male and female students, those parents' who are more discontent with the schools their children are attending and/or have the higher likelihood of migration for children's education seem more likely to send their children to alternative schools.
