  • Cured-in-place-pipe(CIPP) is the most adopted trenchless application for sewer rehabilitation to extend the life of the existing sewer without compromising both direct construction and indirect social costs especially applied in the congested urban area. This technology is globally and domestically known to be the most suitable for partial and full deteriorated pipe structure rehabilitation in a sewer system. The typical design of CIPP requires a significant thickness of lining to support loading causing sewage flow interruption and increasing material cost. This paper presents development of a high strength glass fiber composite lining material for the CIPP application and structural test results. The test results exhibit that the new glass fiber composite lining material has 12 times of flexural strength, 6.2 times of flexural modulus, and 0.5 Creep Retention Factor. These test results can reduce lining design thickness 35% at minimum. Even though taking into consideration extra materials such as outer and inner films for actual field applications, the structural capacity of the composite material significantly increases and it reduces 20 percent or more line thickness as compared to the conventional CIPP. We expect that the newly developed CIPP lining material lowers material costs and minimizes flow capacity reduction, and fully replaceable to the conventional CIPP lining materials.

  • This study examines the awareness of the curriculum of the cabin service major students at 2 year colleges through the CIPP (Context, Input, Process, Product) evaluation model and an empirical analysis on how their awareness affects Service Orientation and Service Hospitality. It was proven that the CIPP evaluation model has a positive effect on the satisfaction of their department, and also has a meaningful effect on Service Hospitality and Service Orientation statistically. However, the satisfaction of their department itself is not associated with the increase of Service Orientation and Service Hospitality so it negatively affected them. Moreover, both the Service Management program(Process) and Service Attitude(Product) have a meaningful effect on Service Hospitality, and Service Hospitality also has a meaningful effect on Service Orientation. So it resulted in a casual relationship among them. As a result, it is desperately necessary to promote an educational environment that will increase the satisfaction of the department and help students to become flight attendants. It is also necessary to increase awareness of the Service Management program(Process) and Service Attitude(Product).

  • This study analyzed nineteen best-practices (161 sub-programs) regarding school library media program. The authors conducted content analysis based on The Library Media Specialist's Taxonomy and the CIPP Model. In the analysis of taxonomy showing the degree of involvement of librarian teachers, Level Seven indicating a concerted effort to promote school library program was the most important (37.6%). Among the ten levels of taxonomy, the highest level (levels 6 to 10, high involvement of librarians) accounted for 65.9%. According to the analysis of the CIPP Model, (Context) most of the excellent programs were aimed at reading education (41.5%) and library use education (11.3%), and more than half (53.8%) cases were initiated by learners' needs. (Input) excellence programs employed various teaching materials and were operated at fixed time. (Process) the programs were run in a variety of ways, mainly with reading instruction (30.4%) and cultural activities (17.3%). (Product) As a fruit of programs, students and parents' satisfaction, students' achievement, self-confidence, and self-improvement were reported.

  • The purpose of this study is to evaluate an airline service training program based on the CIPP model. Evaluation areas were divided into context, input, process, and product. We analyzed the factors which influenced program satisfaction and recommendation of the training program. Two hundred and one learners who participated in an airline service training program were selected for a survey. The results of this study are as follows. The factors which positively influenced training satisfaction were educational goals in context evaluation, interaction between learners and instructors, managing programs in process evaluation, and training performance in product evaluation. The factor which negatively influenced training satisfaction was human resources in input evaluation. On the other hand, the factors which positively influenced training recommendation were educational goal, assessing needs in context evaluation, interaction between learners and instructors, supporting programs in process evaluation, and training performance in product evaluation. The factor which negatively influenced training recommendation was assessing needs in context evaluation. The results of this study are expected to make an important contribution to the development of service training programs in airlines.

  • The purpose of this research was to develop evaluation conformity to operate courses based on CIPP evaluation model dedicated to approval of training organizations. In order to achieve the goal, the researchers scrutinized related documents and precedent studies, initiated the draft for evaluation conformity to operate courses and secured validity for evaluation conformity initiated through Delphi Method survey. To secure validity for evaluation conformity, the researchers conducted two Delphi Method surveys of an expert panel of 22 professionals from relevant fields including officials from the Ministry of Land, Infrastructure and Transport, researchers from Korea Transportation Safety Authority, instructors from approved training organizations and officials from industries. Through the surveys, the researchers determined 4 evaluation areas, 13 evaluation items and 52 evaluation indexes as the evaluation conformity to operate courses for aircraft maintenance mechanics. On top of that, the researchers established evaluation system in the courses for aviation professionals (aircraft maintenance mechanics), and suggested a follow-up studies regarding managing the quality of education.

  • This study investigates the factors affecting the educational satisfaction and the transfer of learning of cyber crime prevention education students in order to confirm the effectiveness of the current education. Based on the CIPP model, we confirmed whether the level of social demand and the level of knowledge in the context evaluation, recency of subjects in the input evaluation and interaction in the process evaluation affect the educational satisfaction and the transfer of learning of the students by conducting the survey for the students. As a result of analysis, it was proved that the level of knowledge, recency of subjects and interaction had a significant relationship with the educational satisfaction and recency of subjects, interaction and educational satisfaction significantly affect transfer of learning. Based on the findings, this study provides a few constructive suggestions to improve the effectiveness of the cyber crime prevention education program.
