This paper shows the case study of risk analysis in an weapon system research and development project. For risk analysis, an advanced stochastic networking technique-VERT (Venture Evaluation and Review Technique) is used. Assumptions for activities of network diagram and conversion methods from PERT ( Program Evaluation and Review Technique) to VERT are discussed. Also, simulation result is presented and discussed.

This study was aimed to investigate the electrolytes and its relationship with acute stroke patients in each stroke type by case-control study. 217 patients with first-ever acute stroke within 2 weeks as the case group(Cases), 146 people without four major risk factors(hypertension, diabetes mellitus, hyperlipidema and ischemic heart disease) as the healthy control group(Normals), and 160 people as the general control group(Controls) were recruited at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital from july 2005 to march 2007 for this case-control study. We analyzed the odds ratio of electrolytes in binary logistic analysis and evaluated each stroke type and general characteristics such as age, sex etc. The level of sodium(Na+) and potassium(K+) were significantly lower in LAA, SVO type of ischemic stroke and hemorrhagic stroke. But the level of chloride(Cl-) had no significant relation with stroke occurance. In this study we demonstrated that low sodium(Na+) and potassium(K+) have an influence on stoke occurance than chloride(Cl-). And we think that the electrolytes must be considered in risk factors of ischemic stroke in Korean and more prospective studies are needed.

This study is a clinical single case study of the application of Theraplay approach for the treatment of children with eating disorder based on Polyvagal Theory. The first research question is how children with eating disorder change through Theraplay. The second research question is to analyze what the therapeutic factors are for changes in children with eating disorder. To do this, I used a qualitative case study method that explores a small number of cases closely and reveals the case deeply. As a result, the client has a sense of security in Theraplay session, expands the window of tolerance and develops a social engagement system. Through these, client become increasingly adaptable and overcome eating disorder. The results of this study can contribute to neuroscience validation of the counseling effect.

The purpose of this study was to examine some of the most important factors for the development of information systems with today's fast-paced, ever-changing, and exciting information system environment. Especially, it was focused to investigate current information technology related to develop information systems, to find some important problems during the development process, and to suggest solutions for the problems. Case research methodology was used because a natural setting was needed and a focus was on contemporary events for this study. Similarly, research phenomena was not supported by a strong theoretical base. The case was the development of an integrated information systems in a specific university. Multiple-case designs were desirable, but single-case study was used because of limitations of site selection. Multiple data collection methods were employed in this study such as documentation, interviews, and direct observation. Some major problems were found during the system development. First, the schedule to complete a project was delayed over six months. Second, the system did not ensure to align organizational goals and information systems goals based on BPR (Business Process Reengineering). Third, there was a difficulty in evaluating request for proposal (RPR) returns and choosing a vendor. Finally, information technology is changing too fast. So, it was very difficult to get the transparency of new technology The study has suggested a few solutions: top management support, matching If planning with business planning, complete project plan and control, user participation, and training Finally, joint application development (JAD) is strongly recommended, which is a workshop that unites management, IT specialists, and knowledge workers to define and specify the logical requirements and technical alternatives for a proposed system.

The purpose of this case study is to verify the usefulness of three costing models and a minimum profit management model that can support the logistics warehouse companies in the Busan Newport Distri-park. This case study investigated traditional costing, activity-based costing (ABC), and time-driven ABC (TDABC); and suggested that an appropriate minimum profit management model is contribution margin analysis. Accordingly, in order to verify the usefulness of models, this case study surveyed the actual cost management conditions of companies, applied the three costing models to the "K" warehouse company in the Busan Newport Distri-park, and undertook a comparative study of the results. This case study produced two main findings. First, TDABC was verified as the most useful and advanced of the three costing models tested. Second, contribution margin analysis was confirmed to be the most suitable model to manage minimum profits for port warehouse companies in the Busan Newport Distri-park.

Objective : This study was carried out to analyze the trends of ophthalmology related articles that have been published in the Journal of Korean Medical Ophthalmology, Otolaryngology, Dermatology(JKOOD). Method : We studied 72 research papers relevant to Ophthalmology that published in JKOOD from 1988 to 2013. All the paper were classified into three categories; original article, review article and case report. We also analyzed the articles according to the sort of diseases. We sub-classified the original articles into three categories descriptive study, analytic study and experimental study. We analyzed the case report according to various types of treatment. Result : 1. The number of searched journals is 72 papers; 21 review articles, 18 original articles, 33 case reports 2. Classification of 18 original articles into three categories; 12 descriptive studies, 0 analytic study, 6 experimental studies. 3. Distribution of diseases in ophthalmology; the percentage of 'strabismus' ranked the highest(25%) in case report. 4. Method of Evaluation in retina disease ; the percentage of fundus photography ranked the highest(50%) Conclusions : It is needed to develop the methods of study in part of eye disease. The studies using modern medical equipment should be increased in ophthalmology of Korean Medicine. It will be helpful to obtain objectivity and increase quality of studies.
