The critical role played by manufacturing performance measurement systems in achieving competitive success is increasingly recognized. Developing an integrated performance measurement model is significant for strategic management. This study consist of se

The research proposes seven elimination rules of redundant gates and blocks in Fault Tree Analysis (FTA) and Reliability Block Diagram (RBD). The computational complexity of cut sets and path sets is NP-hard. In order to reduce the complexity of Minimal Cut Set (MCS) and Minimal Path Set (MPS), the paper classifies generation algorithms. Moreover, the study develops six implementation steps which reflect structural importance (SI) and reliability importance (RI) from Reliability Centered Maintenance (RCM) that a priority of using the functional logic among components is to reduce (improve) the system unavailability (or availability). The proposed steps include efficient generation of state structure function by Rare Event Enumeration (REA). Effective use of importance measures, such as SI and ill measures, is presented based on the number and the size of MCS and MPS which is generated from the reference[5] of this paper. In addition, numerical examples are presented for practitioners to obtain the comprehensive understanding of six steps that is proposed in this research.

Christensen(1997)은 혁신자의 딜레마(innovator`s dilemma)에서 디스크드라이브(disk drive) 시장을 사례분석한 뒤, 성공기업들이 후발자들에게 추월당하는 이유를 와해성 기술(disruptive technology) 때문이라고 주장하였다. 그러나 기술에 초점을 맞췄던 그의 초기 이론은 시간이 지남에 따라 모든 종류의 혁신들을 설명하는데 적용되었으며, 이 과정에서 그는 기술(technology)과 비즈니스 모델(business model)을 개념적으로 구분하지 않고 초기 와해성 이론을 광범위하게 적용하였다(Markides, 2006). 또한 그의 이론은 시장과 산업의 변화를 체계적으로 설명하기 위한 이론적 모형으로서 설명력이 떨어지며, 이론적 모형으로서의 명료함을 높일 수 있는 추가 작업들이 필요하다는 지적이 있었다(Danneels, 2004). 본 연구에서는 C.M. Christensen에 대한 기존 연구들의 지적들을 바탕으로 와해성 이론의 설명력을 높이기 위해서는 와해성 혁신을 하나의 프로세스로 이해하는 것이 필요하며, 이 프로세스를 보다 명료히 이해하기 위해 기술의 혁신과정(phase of technology innovation)과 비즈니스 모델의 혁신과정(phase of business model innovation)으로 나누어 구분하고자 한다. 또한 이 과정에서 기술과 비즈니스 모델을 연결하는 개념으로서 보완기술(enabling technology)의 역할을 강조하고자 한다. 본 연구가 제안하는 개념적 틀의 타당성을 인터넷 쇼핑몰의 성장과정에 적용하여 검증하고자 한다. 그 결과 첫째, Christensen이 와해성 혁신이라고 주장한 인터넷 관련 비즈니스 모델은 성장과정에 있어 기술적 성장과 비즈니스 모델의 성장으로 구분이 가능한 과정이었다. 둘째, 와해성 혁신 단계에 도달하기 위해서는 핵심 기술(core technology)과 비즈니스 모델 사이에 보완기술이 존재하며 보완 기술의 성숙 정도에 따라 비즈니스 모델의 완성도가 결정되어, 혁신의 시장성과가 결정됨을 확인하였다. 따라서, Christensen이 언급한 와해성 혁신은 기술의 혁신과 비즈니스 모델의 혁신으로 구분할 때 보다 명료한 이해가 가능하며, 보완기술이 존재할 경우 비즈니스 모델의 시장성과는 핵심 기술이 와해성 기술로 인정받은 직후보다는 보완기술들이 성숙된 이후에 더욱 확연히 드러남을 증명하였다.

The purposes of this study were to identify the evaluation categories, areas, attributes of the hospital food service and to define the relative importance of the evaluation categories, areas, attributes of the hospital food service using analytic hierarchy process. A survey was conducted from January 8th to 25th in 2007. Questionnaires were mailed to the 310 directors of dietetic departments of hospitals that included 160 primary hospitals, 107 secondary hospitals, and 43 tertiary hospitals. The result of the analytic hierarchy process indicated that relative importance of evaluation category was 0.5259 for food service management and 0.3407 for nutrition care. The food service management consisted of four subcategories, which are equipment standard, sanitation, production, and delivery service. Sanitation(relative importance: 0.2652) was the most important area among the subcategories and it was followed by equipment standard(0.2067), delivery service(0.1864) and production(0.1848). The nutrition care has two subcategories, menu management and meal management. The relative importance of menu management(0.4174) was higher than that of meal management(0.3555). The quality of food service and nutrition care to inpatients can be improved by the evaluation system based on appropriate applications of the developed evaluation indicators for hospital food service systems.

R&D innovation is based on the premises of gaining competitive advantage. Innovation is achieved not only through the development of technology for producing newer and better products, but also gaining and sharing information about consumer demands, changes in the market, and a competitors actions. Investment in R&D can not adequately be fulfilled solely through market functions because of R&D activities imply high-risk, uncertainty, and because R&D has a public-good characteristic. Most past researches have concentrated on managerial methodologies through research of performance, thus the results are related to studies of innovation performance. This research looks into the effect given on R&D innovation by IT factors and provides a model, and further analysis on how IT factors are applied through this model. By developing a model through the process of re-structuring the model with variables based on the convergent and discriminant validity, and in turn confirming and concentrating on major IT factors through analysis, it will be possible to double the R&D Innovation Performance.

The principal objective of this study was to evaluate the perceived management performance and importance level of nutrition teachers by school administrators in the Chonbuk area. Self-administered questionnaires were collected from 142 school administrators. Statistical data analysis was completed using SPSS v. 12.0. Approximately 74.6% of the subjects were men. About 37% of subjects were principals, 33% were vice principals, and 35% were administrative directors, with over 60% aged 40-50 years(p<0.05). Among the 142 schools evaluated, 82.7% were located in urban areas and 17.3% were in ml areas. About 98% of the schools served meals in the dining room(pd0.05). Approximately 68% of the schools employed nutrition teachers and 33.4% had school dietitians(p<0.001). The result indicated that the overall importance level(4.24) was higher than the performance leve1(3.97)(p<0.001). In a survey of the degree of task performance by nutrition teachers, administrators regarded sanitation management was evaluated as the most important performance parameter(4.49), other management attributes as very important parameters(4.41), with nutrition counseling being much less important(2.76) and meal service being least important(3.29; except for classroom teachers). According to the tide of the subjects, evaluations of administrative directors were lower than evaluations of principals and the vice principals. The results indicate that nutrition teachers should not only have meal service management as their main duty, but should also be involved in constructing a life-long health management system for students and teachers by conducting nutrition education and counseling, and should be active in the development of nutrition education programs and in the duties of sanitation management of school meals.

The purpose of this study was to analyze consumer recognition, perceived importance, and satisfaction to create a new apple processed product and to promote its consumption. Data were collected from 527 men and women living throughout Korea through a self-administrated questionnaire. Frequencies, one-way analysis of variance, and Duncan's multiple range were conducted using SPSS v. 17.0 software. Recognition of juice and drinks, milk and dairy products, apple jam, and seasoning was high, while that of the other products was low. Consumer perceived importance of products was higher than consumer satisfaction of products. Quality preservation attributes were sanitation, taste, flavor, place of origin, and convenience of purchase. Attributes for improved consumer post-purchase satisfaction after purchasing were content of apple, quality of apple, price, and certificate of quality. The attributes of content of apple and certificate of quality were statistically different by consumer age.

구조 시스템을 구성하는 구조부재들의 상대적인 중요도를 판별하는 것은 성능기반 지진공학에서 매우 중요한 과정이다. 확률기법의 하나인 First-Order Second Moment 방법을 이용하여, 각 구조부재들의 불확실한 성능 때문에 발생하는 구조 시스템의 요구 성능의 불확실성을 예측할 수 있고, 이런 과정을 통해서 구조부재의 중요도를 판별할 수 있다. 특정한 구조부재의 불확실한 성능에 대한 구조 시스템의 요구성능이 민감할수록 그 구조부재의 중요도는 높아진다는 점을 이용하여 중요부재를 판별한다. 따라서 요구성능의 민감도가 상대적으로 큰 구조부재는 그렇지 않은 부재보다 더 중요하다고 할 수 있다. 개발된 중요부재 판별법은 연성 철근콘크리트 프레임의 중요부재를 판별하는 과정에 적용함으로써 방법을 검증하였고, 적용 가능성을 보여주었다.
