The recent information society is affected by new technologies including EC(Electronic Commerce), CALS(Commerce At Light Speed), EDI(Electronic Data Interchange), telecommuting and teleconferencing. The research goal of this paper is to identify major failure factors to reduce the dysfunction of EC and to suggest possible strategies that overcome those obstacles. The research methodologies of major failure factors are very similar to those of critical success factors which were widely used in MIS research areas. Ideally EC provides the possibility of a win/win situation for vendors and consumers. A survey study was performed using questionnaires. The factor analysis was performed to identify failure factors. Several hypotheses were set up to identify the major failure factors to reduce the dysfunction of EC. The regession analysis was performed to test those hypotheses and to understand the relationships between the major failure factors identified and the performance variables such as satisfaction, usage, and usefulness. Finally, the paper suggests alternatives to activate EC in terms of regulations, social rules, a technological model, etc.

본 연구는 사업타당성이 있다고 평가되었지만 기술사업화가 중지된 사례의 실패원인을 규명하는데 목적이 있다. 이를 위해 여러 경로로 신기술사업화 타당성 평가 보고서 92건을 수집하고, 확실하게 사업화가 실패한 것으로 판단되는 4건에 대하여 추적조사 하였다. 추적조사는 기술사업화 성공과 실패에 관한 여러 이론적 갈래, 즉 기술사업화 성공실패론, 벤처기업 성공실패론 및 기술가치평가론 등의 선행 연구에서 지적된 결과를 중심으로 작성한 분석 틀에 기초하였다. 연구결과 표면적인 신기술사업화 실패원인들은 자금부족과 불가항력적인 요인, 관리력, 대량생산기술 부재 등으로 본 연구의 분석 틀로 제시된 선행연구 결과와 별반 다르지 않다. 하지만, 이면에 숨겨진 핵심 실패 원인은 광의의 기술이해 부족으로 분석되었다. 특히 기술구성 및 기술제품 단계별 소요기술이 존재한다는 점과 기술개발 성공이 기술사업화 성공과 다르다는 것을 이해하지 못한 것이 주요 원인으로 나타났다. 이러한 결과의 배경은 경영자의 전공과 경력이 평가기술과 연관성이 낮거나, 보유경험의 부족으로 분석되었다. 본 연구는 4개의 사례만 조사했다는 점에서 모든 요인을 일반화시키기 어렵지만 다음과 같은 시사점을 도출할 수 있다. 먼저, 표면상의 기술사업화 실패요인들이 선행연구 결과로 설명되었지만, 기술이해 부족이 이면에 숨겨진 핵심 실패요인임을 규명하였다. 둘째, 실패원인들을 분석함으로써 성공적인 기술사업화를 위한 패턴이 제시되었으며, 마지막으로 향후 기술사업화 주체인 경영자와 기업의 역량에 대한 깊은 분석과 기술사업화 평가 모형에 대한 적합성 검토가 필요하다.

To evaluate the quality of a system or its ability to perform a required function, it is necessary to quantify the reliability of that system. The reliability techniques are based on the concept of expected failure rate and average-outage-duration method. For each load point, the expected failure rate, average outage duration and average annual outage time are evaluated. This paper deals with the reliability evaluation for distribution system including the protection relay system. In evaluating the reliability, it suggests a method for the analysis of protective system reliability, that provides a probabilistic measure of the success of the protective apparatus to perform its intended function. The analysis shows the dependency of success on the reliability of many components, and the way this reliability may be enhanced by redundancy.

The purpose of this study is to contribute reference material that provides insight into innovative process management that increases R&D output in commercializing new products. A model of a process from research to commercialization with the cumulative profit and loss curve is put forward and hypotheses related to success and failure are developed at the stages up to product launch. Seventeen large projects that have resulted in successful product launches have been examined from the initial research stage to commercialization. Prefect duration, standardized cumulative R&D expenditures and research resource concentration are analyzed in terms of statistical method and patterns in cumulative profit and loss curves after product sales, as well as the reasons for and other aspects of success/failure are investigated and analyzed. Consequently, valuable information on future management tasks has been obtained such as: (1) project duration differs depending on market sectors, product types and presence/absence of materials research (2) cumulative profit and loss curves can be categorized into four patterns (3) reasons for failure can be divided into technological and market problem categories and (4) these factors have an impact on product sales.

Three years after establishment, companies are said to face a period of risk called the "valley of death." To start a venture company and make it sustainable, the chance of failure must be minimized. According to an in-depth assessment report on special taxation in 2015, the one-year survival rate of Korean companies was about 60 percent and the five-year survival rate about 30%. These rates are low compared to those of major OECD member countries. Worse, such rates in Korea are decreasing year by year. The purpose of this study is to classify the success factors behind venture companies into human capital, social capital and financial capital, and verify through empirical analysis the factors influencing the success of venture companies based on the mediating roles of capability of the startup team and that for innovation. To find the success factors behind venture companies, this study first examined the theories derived from previous studies. SPSS 21 was used as the study method, while descriptive statistics, exploratory factor analysis and CMB test were conducted. In addition, SmartPLS 2 was used for confirmatory factor analysis, hypothesis test, mediation effect. The results of this study can help efforts toward job creation and economic revitalization pursued by the creative economy policy of the incumbent Korean administration. They can also be used as the cornerstone for venture companies in their pursuit of success.

Background Some diabetic feet heal without complication, but others undergo amputation due to progressive wounds. This study investigates the risk factors for amputation of diabetic feet. Methods A total of 55 patients who visited our institution from 2008 to 2012 were included in the study. The patients with abnormal fasting blood sugar levels, lower leg vascularity, and poor nutrition were excluded from the study group, and the wound states were unified. The patients were categorized into a treatment success group (n=47) and a treatment failure group (n=8), and their hemoglobin A1C (HgA1C), C-reactive protein (CRP), white blood cell count (WBC), and serum creatinine levels were analyzed. Results The initial CRP, WBC, and serum creatinine levels in the treatment failure group were significantly higher than that of the treatment success group, and the initial HgA1C level was significantly higher in the treatment success group. The CRP and WBC levels of both groups changed significantly as time passed, but their serum creatinine levels did not. Conclusions The initial CRP, WBC, and serum creatinine levels were considered to be risk factors for amputation. Among them, the serum creatinine level was found to be the most important predictive risk factor. Because serum creatinine represents the renal function, thorough care is needed for the feet of diabetic patients with renal impairment.

The authors have observed 207 cases on the results of pulp healing after pulp capping. The results are as follows: 1) We could have success-rate of 70% in 207 cases at the ages from 14 to 59. 2) The success-rate in male is 72.4% in 87 cases, and female is 67.5% in 120 cases. So we observed that success-rate was slightly higher in male than female. 3) In view of age group, it was observed that success-rate was 79% in 129 cases at 30 ages below, 62.5% in 40 cases at 30-40 ages, 47.3% in 38 cases at 40 ages over. So we found that the failure-rate was increased by aging.

Background: This study aimed to identify the characteristics of the referral and return of patients to clinics in the endocrinology and cardiology departments at the National Health Insurance Service Ilsan Hospital to evaluate the "referral and return of patients to clinics" program and reduce the rate of returning patients. Methods: From May 2018 to December 2020, we identified the number of visits to referral hospitals and hospital usage status at Ilsan Hospital after returning to clinics. We also identified the patients who returned to Ilsan Hospital within 6 months, defined as "failure to transport," among those recommended to be transported to clinics of the Medical Cooperation Center. Additionally, we evaluated the characteristics of the "failure to transport" patients. Results: Among the returning patients, the rate of visiting Ilsan Hospital within 6 months was higher in cardiology than in endocrinology (25.1% vs. 16.7%). Older age, more severe disease, and more number of visits to the department were associated with a high rate of failure to transport. The rate of failure to return was low in cases diagnosed with hyperlipidemia/lipoprotein metabolism disorder. With respect to diabetes, the rate of failure to transport differed according to each type of diagnosis of diabetes. Conclusion: The success rate of the "referral and return of patient to clinics" program differed based on each patient's characteristics, department of visit, and diagnosis. Individualizing according to the visit department and diagnosis is required to ensure successful transfers, and infrastructure expansion and institutional arrangements must be facilitated.
