소프트웨어 재사용을 위한 콤포넌트의 식별은 사용자에게 적절한 콤포넌트가 발견되지 않았을 때 예비 콤포넌트에 대한 정보를 제공하는 안내역할을 수행하여야만 한다. 또한, 믿을 수 있는 소프트웨어 컴포넌트의 재사용은 각 새로운 어플리케이션에 대해 같은 컴포넌트를 재설계하거나 재 코딩하는 것보다 훨씬 위험이 적고 효과적이다. 본 논문에서는 먼저 재사용 프로세스에 대하여 알아보고 이어서 재사용 가능한 컴포넌트 구축을 위한 재사용 모형 및 구축방법을 분석 하고자하며, 이를 이용한 재사용 가능한 컴포넌트에 대하여 제안하고자 한다. 이는 향후 효율적인 프로그램을 설계하고 작성하는데 도움이 될 것이다.

This study reviewed photos of women's jackets shown at Milano Collections from 2013 S/S to 2017 F/W to identify the variations and trends in their structural components and design elements with respect to year and season. 576 photos, which consist of 276 S/S jackets and 300 F/W jackets by renowned Italian luxury fashion brands; Giorgio Armani, Gucci, Fendi, Max Mara and Jil Sander, were analyzed. Some of the highlighted findings are as follows; in the structural aspects, the H-line silhouette, below waist to hip line length, natural shoulder line and single button closure were the most frequently appearing components among all the jackets. For the design elements, the largest number of jackets was made of woven fabric in single color, while fur was mostly used in F/W seasons for its warmth, heaviness and bulky appearance. From the results, it was established that variations were made to the jacket components and design elements to the extent that they convey predominant jacket styles with a certain level of practicality and performance. However, the study also found that some of the jackets demonstrated design diversity and innovation by adopting daring styles, bold materials and colors. As the findings of this study identified the variations and trends in women's jacket components in recent years, they can be applied towards developing high end women's jackets to meet the demands and distinctive needs of luxury clothing buyers and distributors.

The various software engineering techniques have been appeared in order to cope with the software crisis since 1980's. Currently, the research against the techniques likes the Design pattern, Component which improve the software's re-use are spread out. Also S/W Development Process are interested intensively which attempts the quality and a increasing productivity of software development with the basic policy. The design pattern is the solution against the problem which occurs repeat in a specific area. Many design pattern are developed and researched, but the method which accommodates the developed design pattern efficiently in the phase of analysis and design software development process is not good enough, so it is the actual applying technique is difficult. In this paper we suggest and the “UML components+” which is a efficient component development process from customizing EJB based the J2EE using the “UML Components” which is a component development methodology. Applying J2EE pattern efficiently with UML components+, there is a possibility of efficiency in the component development based pattern.

Thermal design fur satellite propulsion system has been performed. Overall design requirements and the constitution for propulsion system is described. To meet the thermal design requirements, both a primary and a redundant heater circuit, each with two thermostats placed in series, will protect each hydrazine-wetted components, even if one heater circuit fails to operate. Heater power is turned off if any one of these thermostats is opened at its higher setpoint. Thus, even if one thermostat is failed closed, the second thermostat will turn off the heater. All such components shall be insulated with MLI. Propulsion heater sizing based on the constant worst cold case condition is conducted through thermal analysis. All heaters selected fur propulsion components operate to prevent propellant freezing satisfying the thermal requirements for the propulsion subsystem over the worst case average voltage, i.e. 25 volts.

This study is a theoretical exploration of project-based service-learning and its application in designing pre-dental curricula. As a response to the limitation of community service courses, service-learning has been implemented as pedagogy in higher education practices. Service-learning connects service and learning by engaging students in activities that address community needs with intentionally designed learning opportunities while adding value to and transforming both service and learning. Project-based service-learning is an extended and more active version of service-learning. Whereas service activities are arranged by instructors in the original service-learning, project-based service-learning provides students with opportunities for exploring problems and root causes on site and then devising and implementing solutions of their own using their talents and creativity. This study proposes a theoretical approach to project-based service-learning and suggests six design components, namely, related curriculum, reflection, reciprocity, service and community engagement, evaluation and recognition, and creative problem solving. Based on the components, 20 design strategies are formulated. The exploration is aimed to provide design guides for professionals attempting to implement project-based service-learning in higher education.

Gate poly-silicon critical dimension is a prime characteristic of a metal-oxide-semiconductor field effect transistor. It is important to achieve the uniformity of gate poly-silicon critical dimension in order that a semiconductor device has acceptable electrical test characteristics as well as a semiconductor wafer fabrication process has a competitive net-die-per-wafer yield. However, on gate poly-silicon critical dimension, the complexity associated with a semiconductor wafer fabrication process entails hierarchical variance components according to run-to-run, wafer-to-wafer and even die-to-die production unit changes. Specifically, estimates of the hierarchical variance components are required not only for disclosing dominant sources of the variation but also for testing the wafer-level uniformity. In this paper, two experimental designs, a two-stage nested design and a randomized complete block design are considered in order to estimate the hierarchical variance components. Since gate poly-silicon critical dimensions are collected from fixed die positions within wafers, a factor representing die positions can be regarded as fixed in linear statistical models for the designs. In this context, the two-stage nested design also checks the wafer-level uniformity taking all sampled runs into account. In more detail, using variance estimates derived from randomized complete block designs, Duncan's multiple range test examines the wafer-level uniformity for each run. Consequently, a framework presented in this study could provide guidelines to practitioners on estimating the hierarchical variance components and testing the wafer-level uniformity in parallel for any characteristics concerned in semiconductor wafer fabrication processes. Statistical analysis is illustrated for an experimental dataset from a real pilot semiconductor wafer fabrication process.

모듈러 제품 설계는 유연한 제품 수정, 제품 개발 및 생산 리드타임 감소, 제품의 다양성 증대와 같은 많은 장점들이 있다. 모듈러 제품 설계의 목적은 여러 개의 모듈들로 구성된 제품의 아키텍쳐를 효율적으로 개발하는 것인데, 이들 모듈들은 컴포넌트들 간 물리적, 기능적 상호관계 분석을 토대로 컴포넌트들 간의 유사성을 최대화함으로써 만들어 질 수 있다. 본 연구에서는 모듈러 제품 설계의 핵심 작업인 모듈화를 위하여 3개 단계로 이뤄진 체계적인 절차를 제시하고자 한다. 첫 번째 단계는 컴포넌트들 간 물리적, 기능적 상호관계 분석을 통한 컴포넌트들 간 상관 관계 매트릭스를 구성하는 것이고, 두 번째 단계는 컴포넌트들 간 상관 관계를 최대화하는 컴포넌트들의 군집들을 찾아내기 위하여 네트워크 흐름으로 모델링하는 것이다. 마지막으로 세 번째 단계에서는 선형 계획 모형인 네트워크 흐름 모델을 풀어서 컴포넌트들의 군집들을 찾아내고 이들을 모듈화 하는 것이다. 본 연구에서 제시한 절차의 이해와 실제 적용을 위하여 진공 청소기 모듈화 사례에 적용해 보고 절차의 타당성을 보여준다.
