본 연구의 목적은 첫째, 프로세스 기획 역량이 신제품 개발 성과에 미치는 영향을 검증하고자 한다. 특히, 프로세스 기획 역량이 개별적인 프로젝트의 성과가 아닌 제품군 전체의 성과에 미치는 영향력을 검증하였다. 둘째, 개발 역량 간 상호작용이 신제품 개발 성과에 미치는 영향을 살펴보았다. 본 연구는 국내 103개 제조기업으로부터 수집한 설문응답 분석에 기초하였다. 제품군 개발은 크게 두 가지 유형의 프로젝트 (플랫폼 및 파생제품 개발)으로 구분된다. 본 연구에서는 두 가지 프로젝트 유형 중, 제품군 성공의 중심적인 역할을 수행하는 플랫폼 제품을 중심으로 분석하였다. 본 연구결과 제품군의 기술적 성과 및 상업적 성과 향상을 위해 우수한 프로세스 기획 역량이 필요함을 보여준다. 또한 기술개발 역량은 기술적 성과에 직접적으로 유효한 영향을 미치지는 않지만, 프로세스 기획 역량과 상호작용을 통해 기술적 성과 향상에 영향을 미치는 것을 확인하였다.

Purpose : This study compared before and after emergency patient evaluation education of the 1st graders at the department emergency medical technology(EMT) students, and analyzed its effects on patient evaluation ability after education. The aims of this study was to develop effective educational program and to provide basic materials for its educational method. Methods : This study was carried out by 66 first graders attending the department of emergency medical technology(EMT) at a college in G province and data were collected from Apr. 1 to 2, 2009. The questionnaire consisted of knowledge of emergent patient evaluation, academic self-efficacy, and technical performance after emergent patient evaluation education. We analyzed the influence of knowledge and academic self-efficacy on accurate technical performance with SPSS 14.0 version. Results : 1. In knowledge score, it was 9.27 before education and increased to 35.19 after education and that there was statistically significant difference. In academic self-efficacy, task difficulty preference scored 2.73 before education and 3.97 after education, self-control efficacy scored 2.84 before education and 4.05 after education, self-confidence scored 2.45 before education and 4.21 after education. There were statistically significant increases after education. Technical performance scored 0.00 before education, but it scored 18.78 after education and there was statistically significant increase after education. 2. In sex as one of general characteristics, self-confidence which was sub-factor of academic self-efficacy scored higher in male students(4.28) than in female students(4.10). There was statistically significant difference(p < 0.05). 3. Knowledge had positive correlation with self-control efficacy which was the sub-factor of academic self-efficacy(r = 0.249, p < 0.05) and self-confidence which is the sub-factor of academic self-efficacy had the positive correlation with technical performance(r = 0.258, p < 0.05). 4. Self-confidence which was the sub-factor of academic self-efficacy(B = 0.372, p < 0.05) had statistically significant influence on technical performance. ability of self-confidence to explain technical performance(R2) was 11.10%. Conclusion : From the results of this study, it is necessary that EMT students should learn professional first aid, accurate patient evaluation through self-efficacy development.

In the bidding stage of turn-key based plant construction contracts, owners provide design and performance basis for contractors instead of giving design drawing. To win the bid for a plant construction, the contractors should be obliged to satisfy and ensure owners'requirements such as design and performance basis in a plant construction project, In other words, owners imposes technical risk of the design to the contractors by specifying responsibility for the analysis and verification of the plant construction. Thus, it is very important that contracters make accurate and realistic basic design plan in a short period of time. To deal with such a situation, we propose a systems engineering approach for the analysis and management of the technical risk. Specifically, we first: 1) Analyzes technical risk related with the plant design information for the bidders, followed by 2) Developing stakeholder requirements for the basic engineering design, and 3) System requirements for dealing with technical risk. Also, in this paper, we proposed converting method from MOE(Measure of Effectiveness) to MOP(Measure of Performance) in the risk analysis. To show the effectiveness of the proposed method, we carried out a case study.

This paper presents a structural performance assessment of a historical masonry clock tower both using numerical and experimental process. The numerical assessment includes developing of finite element model with considering different types of soil-structure interaction systems, identifying the numerical dynamic characteristics, finite element model updating procedure, nonlinear time-history analysis and evaluation of seismic performance level. The experimental study involves determining experimental dynamic characteristics using operational modal analysis test method. Through the numerical and experimental processes, the current structural behavior of the masonry clock tower was evaluated. The first five experimental natural frequencies were obtained within 1.479-9.991 Hz. Maximum difference between numerical and experimental natural frequencies, obtained as 20.26%, was reduced to 4.90% by means of the use of updating procedure. According to the results of the nonlinear time-history analysis, maximum displacement was calculated as 0.213 m. The maximum and minimum principal stresses were calculated as 0.20 MPa and 1.40 MPa. In terms of displacement control, the clock tower showed only controlled damage level during the applied earthquake record.

The military services have sought to improve the overall quality, management, and delivery of military technical information in all of its aspects. The efforts concentrated on developing IETM(Interactive Electronic Technical Manual) by using the application of computer technology for the storage, control, and presentation of maintenance, system-operation, training, and other forms of logistic-support technical information. In this paper, the methodologies are presented to evaluate the operational effectiveness of IETM which consists of confirmity and performance. Confirmity is evaluated by the check-sheet based on the standard of CALS, and performance by the comparison of the technician performance between IETM and paper-TM.

The present study analyzed empirically the structural relationship among characters, market orientation and performance of CEO's in small and medium-sized companies. The analysis showed that market orientation is affected by CEO's characters in the industry. It was also revealed from the analysis that the business performance and technical renovation of small and medium-sized companies rely fairly on their market orientation. These findings are believed to have great significance in the process of creating market orientation by the industry. That is, CEO's will may play a very important role in pursuit of market orientation and, at the same time, may act as a vital factor for small and medium-sized companies to achieve business performance and to realize technical renovation.

This paper reviewed the relationship between innovation(organization innovation, personnel innovation, product innovation, process innovation) and firm performance in small business. Based on the responses from 218 firms, the results of multiple regression analysis showed that personnel innovation, product innovation, and process innovation effect positively on all firm performance(sales, profit, market share, customer satisfaction), and organization innovation effects positively only on market share and customer satisfaction. The results of hierarchical regression analysis showed that technical innovation(product innovation, process innovation) effects more positively on sales, profit and customer satisfaction than administrative innovation(organization innovation, personnel innovation).
