We studied how to achieve successful implementation of massive research and development projects requiring collaboration among industries, universities and government-supported research institute. We have set up an engineering process innovation model to be deemed most adequately for all practical purposes, relying on the theoretical studies on the merits and analysis of the effect of the information system based on Milestone Management, Work Breakdown Structures and Web, which is known to be effective for research project (schedule) management and the objective management, and implemented a real-world web-based project objective management system. After a review of various R & D Project Schedule Management methods, we found that this information system was very compatible with project objective management. This project objective management information system carries out research and development projects effectively and efficiently, getting together in cyber-space and sharing information, and has been equipped with an Early Warning Subsystem to allow for pre-analysis and timely response to potential problems arising from the course of the project. The system also contains an Executive Information System that in real time, automatically provides the management information required by managers with the rate of project progress (achievement, fulfillment and delay). Lastly, actual progress can be cross-checked through both on-line objective management on the web-based information system and design review meeting held on site, to improve the efficiency and validity of the information system. Moreover, overall effect was analyzed through questionnaires on how well the system and generated information meet requirements and on the ultimate impact of the system upon objective management and communication. The questionnaire on the system effect revealed that the information system was useful to objective management and communication, and that the quality of the system was more than acceptable as well.

This study tries to seek the is the realistic improvements and legislative measures about current medical advertising which was in the Court on 12 May 2015 by presenting and discussion the understanding, problems and its alternative direction of pre-deliberation on the existing law which is the decision on the constitutionality of health care advertising regulated health care advertising General commercial advertising has the right which have to be protected as the terms of the protection of know and freedom of expression and advertiser's there are sure to be in a value to be protected. Medical advertising is also a person in addition to the absolute value that includes both Due to the particularity of medical advertising in terms of life and the right to health Until now, this has been the target of strong regulations are changing the policy of gradual deregulation in our country, including the country. Medical advertising on the current medical law had been to be checked by pre-deliberation of the executive power. However, due to unconstitutional, in the circumstances which a false hype is flooding and increasing, it has been realized that the fair competition of medical community, life and health rights of the people are threatened by in reverse. In this regard, the abolition of the pre-deliberation system of medical advertising can be welcomed by abolition of the old system which is the legal and institutional censorship. Since its abolition, the alternative policy direction is insufficient also it is not clear. Therefore we need to study this. Therefore, in this paper, we try to find general theoretical background and problem of pre-deliberation system of medical advertising. Also, as trying to find feasibility or ambiguity of regulation and issues about medical advertising on medical law, we argued the provision of special measures of the medical advertising for introduction of integrated medical advertising deliberation committee which can ensure the independence and autonomy, strengthening of the monitoring on the internet advertising, legal resolving through amendments, strengthening of penalties, and establish special measures of medical advertising for the medical privatization and demand for the foreign medical tourist, etc. Empirical study about practical regulatory measures of medical advertising which converged the various opinions of consumer groups, government and academia, and medical community, and we expect hope to see the more realistic alternative provision.

This review introduces advances in clinical and pre-clinical single photon emission computed tomography (SPECT) and positron emission tomography (PET) providing noninvasive functional images of biological processes. Development of new collimation techniques such as multi-pinhole and slit-slat collimators permits the improvement of system spatial resolution and sensitivity of SPECT. Application specific SPECT systems using smaller and compact solid-state detector have been customized for myocardial perfusion imaging with higher performance. Combined SPECT/CT providing improved diagnostic and functional capabilities has been introduced. Advances in PET and CT instrumentation have been incorporated in the PET/CT design that provide the metabolic information from PET superimposed on the anatomic information from CT. Improvements in the sensitivity of PET have achieved by the fully 3D acquisition with no septa and the extension of axial field-of-view. With the development of faster scintillation crystals and electronics, time-of-flight (TOF) PET is now commercially available allowing the increase in the signal-to-noise ratio by incorporation of TOF information into the PET reconstruction process. Hybrid PET/SPECT/CT systems has become commercially available for molecular imaging in small animal models. The pre-clinical systems have improved spatial resolution using depth-of-interaction measurement and new collimators. The recent works on solid state detector and dual modality nuclear medicine instrumentations incorporating MRI and optical imagers will also be discussed.

Purpose: The purpose of the study is to develop and to evaluate a internet-based social support program for the mothers of congenitally abnormal children. The theoretical basis of the study is the moderating effect model of social support theory (Cobb, 1976). Methods: In first phase, an internet support program was developed according to the practical web development stages proposed by Boling and Frick (2002). In the second phase, the internet support program was provided and evaluated to 18 mothers who reared congenitally abnormal children from March to May 2008. Results: In the first stage, demands of the program were collected from interviews of eighteen mothers of congenitally abnormal children of ages one to three. At the same time, literature review and validity of the contents were also examined. In the second stage, the correspondence of the program contents to the social support needed was also examined. In the third and fourth stages, prototype of the social program was prepared in documents and that of computer program was prepared. In the final stage, an internet-based web site was constructed. The social support provided by the web site were composed of informational support, emotional support and appraisal support including bulletin board system and chatting service. After program development, pre-tests and post-test were performed to investigate the effect of the program on maternal confidence and mood. Data were analyzed using Wilcoxon signed rank test. The analysis showed that maternal confidence of post-test was improved than that of pre-test with statistically meaningful figure (Z=-2.54, p<.05). The positive mood of post-test was also improved than that of pre-test and the result was statistically supported (Z=-2.20, p<.05). Conclusion: It is suggestive that the internet based social support programs is accessible and appropriate service to congenitally abnormal children's mother. It is necessary to develop and use the internet based social support programs in public health system.

Purpose: To develop the dose volume histogram (DVH) management software which guides the evaluation of radiotherapy (RT) plan of a new case according to the biological consequences of the DVHs from the previously treated patients. Materials and Methods: We determined the radiation pneumonitis (RP) as an biological response parameter in order to develop DVH management software. We retrospectively reviewed the medical records of lung cancer patients treated with curative 3-dimensional conformal radiation therapy (3D-CRT). The biological event was defined as RP of the Radiation Therapy Oncology Group (RTOG) grade III or more. Results: The DVH management software consisted of three parts (pre-existing DVH database, graphical tool, and $Pinnacle^3$ script). The pre-existing DVH data were retrieved from 128 patients. RP events were tagged to the specific DVH data through retrospective review of patients' medical records. The graphical tool was developed to present the complication histogram derived from the preexisting database (DVH and RP) and was implemented into the radiation treatment planning (RTP) system, $Pinnacle^3$ v8.0 (Phillips Healthcare). The software was designed for the pre-existing database to be updated easily by tagging the specific DVH data with the new incidence of RP events at the time of patients' follow-up. Conclusion: We developed the DVH management software as an effective tool to incorporate the phenomenological consequences derived from the pre-existing database in the evaluation of a new RT plan. It can be used not only for lung cancer patients but also for the other disease site with different toxicity parameters.

This paper deals with enhancement of the high school equalization assignment system to be executed by the allied entrance examination after the applicants graduated from their middle schools. In prevailing opinion, because educational demander's will has not been considered under the current system, it whose merits have been covered is required to be improved. If the application system of the entrance examination for the high schools will be returned, a situation that it will result in irregularity of the middle school education and in overheating entrance examination seems to appear explicitly. Since the averages of the allied entrance examination score of all the high schools, achieved by the equalization-application nearest assignment system which is named by writers of this paper, are equal, our system is good for maintaining the merits of the current system. More than 50% educational demander's will has been reflected by our system, so that we come to the conclusion that our system is excellent in all the systems verified up to now. Assigning students to the high school to make an average difference between three and five score, we expect that relection rate of the educational demander's will be increased more than 60%.

Truck dispatching is one of the most commonly occurring problems of transprot management. We developed an interactive decision support system named IDSSTD, for the truck dispatching problem where two conflicting objectives are treated and travel speed varies depending on the passing areas and time of day. The IDSSTD aids the decision-making process by allowing the user to interact directly with the database, to direct data to a decision model, and to portray results in a convenient form. The IDSSTD is consisted of two major interactive phases. The pre-scheduling interactive phase is to reduce the complexity of a given problem before applying the BC-saving heuristic algorithm and the post-scheduling interactive phase is to improve practically the algorithmic solution. The IDSSTD has the capabilities of its own manipulation(analysis and recommendation) and diverse graphic features in order to facilitate a user's interaction.

In vitro maturation (IVM) of oocytes is the procedure where the immature oocytes are cultivated in a laboratory until they are mature. Since IVM oocytes generally have low developmental competence as compared to those matured in vivo, development of an optimal IVM culture system by fine-tuning culture conditions is crucial to maintain high quality. In-depth knowledge and a deep understanding of the in vivo physiology of oocyte maturation are pre-requisites to accomplish this. Within ovarian follicles, various signaling pathways that drive oocyte development and maturation regulate interaction between oocytes and surrounding somatic cells. This review discusses the sonic hedgehog (SHH) signaling pathway, which has been demonstrated to be intimately involved in folliculogenesis and oocyte maturation. Advances in elucidating the role of the SHH signaling pathway in oocyte maturation will aid attempts to improve the current inferior in vitro oocyte maturation system.
