This paper presents several case studies of asian colleges's co-op program for successful operation of KOREATECH IPP(Industry Professional Practice) program. The IPP program is a new educational model that combines academic study and industrial work through university-industry cooperation. The IPP experience will lead the university graduates to improve their employment competencies and will be a key to solve the problems of the labor mismatch between university and industry. We will discuss and analyze the strengths and the weaknesses of the Co-op programs of the Kyoto sangyo university, the Hong Kong polytechnic university and the suranaree university in thailand. Based on these case studies, we summarized several benchmarking points for the successful operation of IPP program.

Koreatech has recently adopted a long-term co-op program called IPP (Industry Professional Practice) to address problems in engineering education of Korea, but it is anticipated to face many difficulties in implementing the program due to lack of relevant experiences in Korea. In this regard, a performance evaluation scheme is required to improve the operational efficiency and judge the effectiveness of the IPP program at the same time. This study aims to develop a comprehensive performance evaluation model for the Koreatech co-op program on the basis of Kirkpatrick's four stage performance evaluation model for training programs. For this purpose, thorough review on the program evaluation literature and in-depth analyses of overseas cases of co-op performance evaluation were also conducted. The study is expected to help enhance the effectiveness of the IPP program and promote buy-in of a range of stakeholders for the first long-term co-op program in Korea.

For use as recyclable power cable insulations without dielectric oil, technology trends of IPP based thermoplastic polyolefin elastomer(TPO) nanocomposites were reviewed. In 2010 research results of IPP nanocomposite dielectrics for power capacitors showed promising high voltage properties except dielectric loss. Research of IPP based TPO nanocomposites for automotive exterior parts revealed considerable improvements of mechanical properties including impact strength, especially minimization of compatibilizer content, the origin of dielectric loss. A study on electrical properties of IPP based TPO nanocomposites containing a few weight percent of nanofillers for power cable insulations is suggested.

This paper is aimed to introduce the practical case about the operation system consisted of academic curriculum and portal system for the IPP implementation. After benchmarking the preceding universities system, the academic program is renewed for our student's participation without difficulty with semi-quater semester system. The portal system is designed to focus on the studentindustry matching and the adaptation to disparate databases of the university. The IPP operation system have been constructed to fulfill the 1st-year-plan as a participating university in 4th period support of Korean government. The first year project performance with constructed system indicated that in many categories of the survey conducted by the IPP management institution, the satisfaction level in that system exceeded the average value of the IPP participating universities nationwide. The improvement direction was set after analyzing the results of the survey.

The purpose of this study was to investigate the factors affecting the satisfaction of the program for the quality improvement of the long-term on-site training operated by the university. The survey questionnaire data of 393 students who participated in the IPP program of K university were used to analyze the data and the results were as follows: First, factors affecting the satisfaction of long-term on-site training were corporation factors and university factors. Specifically, job contents, coaching, job scope, center support were found to have a significant effect in that order. Second, the factors affecting the satisfaction of long-term on-site training were different according to group characteristics(IPP participation types, major types, corporation types). It is necessary to intensively manage the common and important corporation factors, and it is necessary to closely examine each factor derived from group characteristics, and to support and strive at university level according to group characteristics in student counseling and matching.

This study empirical analysed how student's major satisfaction affected job-seeking stress. It also analysed the mean differences of major satisfaction and job-seeking stress between two groups(IPP experienced, non-experienced groups). 200 data were collected from the field survey questionnaires administered to a quota sample of university students who had IPP experience or non-experience. For hypothesis testing, the IBM SPSS Statistics 24.0 was used. As a result of empirical research analysis, first, it was found that major satisfaction had a negative effect on job-seeking stress. Among major satisfaction sub categories, subject satisfaction had negative effects on cognitive and physical stress, and relationship satisfaction also had negative effects on cognitive and physical stress. On the other hand, general satisfaction had a negative effect only on emotional stress. Second, there was a significant difference between major satisfaction and job-seeking stress. Major satisfaction of IPP experience group was high, and the job-seeking stress was low. Third, in the group of students who practiced IPP, subject satisfaction had a negative effect on emotional and physical stress, whereas subject satisfaction in the group of students who did not practice IPP had no significant effect on job-seekingt stress. In the case of relationship satisfaction, only non-practice groups had a negative effect on cognitive stress and physical stress. In the case of general satisfaction, only the IPP group showed negative effects on emotional stress. The results of this study supported the preceding studies that major satisfaction had an effect on job-seeking stress, and the study was meaningful in that it confirmed that there were differences between the IPP experienced, non-experienced groups. Based on this results, academic and practical implications were suggested.

Paclitaxel is one of the best anticancer agents that has been isolated from plants, but its major disadvantage is its dose-limiting toxicity. In this study, we obtained evidence that the active mutant IPP5 ($8-60hIPP5^m$), the latest member of the inhibitory molecules for protein phosphatase 1, sensitizes human cervix carcinoma cells HeLa more efficiently to the therapeutic effects of paclitaxel. The combination of $8-60hIPP5^m$ with paclitaxel augmented anticancer effects as compared to paclitaxel alone as evidenced by reduced DNA synthesis and increased cytotoxicity in HeLa cells. Furthermore, our results revealed that $8-60hIPP5^m$ enhances paclitaxel-induced G2/M arrest and apoptosis, and augments paclitaxel-induced activation of caspases and release of cytochrome C. Evaluation of signaling pathways indicated that this synergism was in part related to downregulation of NF-${\kappa}B$ activation and serine/threonine kinase Akt pathways. We noted that $8-60hIPP5^m$ downregulated the paclitaxel-induced NF-${\kappa}B$ activation, $I{\kappa}B{\alpha}$ degradation, PI3-K activity and phosphorylation of the serine/threonine kinase Akt, a survival signal which in many instances is regulated by NF-${\kappa}B$. Together, our observations indicate that paclitaxel in combination with $8-60hIPP5^m$ may provide a therapeutic advantage for the treatment of human cervical carcinoma.

The purpose of this study is to suggest implications for maximizing the effectiveness and efficiency of IPP work-learning by studying the effects of the personal characteristics of trainees and firm's field teacher on trainees' employability. The following conclusions were drawn by verifying the causal relationship between factors based on a questionnaire (157 copies) distributed to 200 trainees (learning workers) of 9 universities participating in IPP work-learning training. First, in order to increase the employability of IPP trainees, it is necessary to select trainees with strong core competencies and failure tolerance by verifying individual characteristics of trainees. Secondly, companies should appoint senior staff with strong leadership and teaching capacity as corporate field teachers, and corporate field teacher training institutions should reinforce the training to improve their leadership. Third, work-learning companies should be selected as those with high social integration and absorption capacity, and those companies should try to build an organizational culture of acquiring and learning new technologies. The results of this study are expected to contribute to enhancing the effectiveness of work-learning training by establishing a training system that can systematically select trainees and participating companies and enhance the training capacity of companies and field teachers.
