Information systems quality engineering is one of the most problematic areas in practice and research, and needs cooperative efforts between practice and theory [Glass, 1996]. A model for evaluating the quality of system development process and ensuing success is proposed based on information processing theory of project unit design. A nomological net among a set of quality variables is identified from prior research in the areas of organization science, software engineering, and management information systems. More specifically, system development success was modelled as a function of project complexity, system development modelling environment, user participation, project unit structure, resource availability, and the level of iterative nature of development methodology. Based on the model developed from the information processing theory of project unit design in organization science. appropriate quality metrics for each variable in the proposed model are matched. In this way, a framework of relevant systems development and success quality metrics for controlling systems development processes and ensuing success is proposed. The causal relationships among the constructs in the proposed model are proposed as future empirical research for academicians and as managerial tools for quality managers. The framework and propositions help quality manager to select more parsimonious quality metrics for controlling information systems development processes and project success in an integrated way. Also this model can be utilized for evaluating software quality assurance programmes, which are developed and marketed by many vendors.

To estimate fuel consumption of a vehicle, a car can be tested on chassis dynamometer. In this case, test causes a lot of time and money. To predict the fuel efficiency of vehicles in the design stage or early stage of development, the development of computer simulation model is necessary. Using simulation to predict the fuel consumption, the driving model which consists of time-velocity profile and time-grade profile is necessary In this study, vehicle model is developed in MatLab/simulink to estimate real driving fuel consumption rate with time-velocity profile, time-shift gear profile and time-grade profile. Vehicle model consists of driver model, engine model, power train model, and so on. On-road vehicle tests to verify the vehicle model are carried out for analyzing the result of simulation and comparing with those of the experiments.

This study postulates a partial mediation model(study model I) and a whole mediation model(study model II) to examine the effect on endogenous rural development of local innovation capability strengthening in the local industry promotion project, the establishment of promotion system, and the revitalization of local economy. To accomplish study purposes, 169 response samples from 85 project groups which drive the local industry promotion project were verified using SPSS 12.0 and AMOS 5.0. The results showed that in the partial mediation model, the local innovation capability strengthening had a significantly positive effect on the establishment of promotion system, the establishment of promotion system had a significant effect on the revitalization of local economy, and the revitalization of local economy had a significant effect on the endogenous rural development, while the establishment of promotion system and local innovation capability strengthening didn't have effect on the endogenous rural development. In the whole mediation model, the local innovation capability strengthening had a significant effect on the revitalization of local economy, the establishment of promotion system on the revitalization of local economy, and the revitalization of local economy on the endogenous rural development. According to the verifications of study model I and II, the endogenous rural development is achieved after the revitalization of local economy through the establishment of promotion system and the local innovation capability strengthening. From these results, this study presents suggestions, limits of study and directions in the future study.

객체지향 개발 방법론을 적용하는 소프트웨어 개발 프로젝트에서 개발 노력 추정 기법으로 사용사례점수(UCP, Use Case Point)에 대한 연구가 계속되고 있다. 기존의 연구는 기술적 요인과 환경적 요인을 적용한 AUCP(Adjusted Use Case Point)에 상수를 곱하여 개발 노력을 계산하는 선형모델을 제시하고 있으나, AUCP와 UUCP(Unadjusted Use Case Point)를 이용하여 개발노력을 추정하는 통계적인 모델은 제시되지 않고 있다. 소프트웨어 규모가 증가함에 따라 개발 기간이 기하급수적으로 증가하는 선형 회귀모델이 부적합하다는 사실과 UCP 계산과정에서 TCF(Technical Complexity Factor)와 EF(Environmental Factor)를 적용에 따른 FP(Function Point) 오차 발생 문제점을 확인하였다. 이 논문은 사용사례점수를 기반으로 하여 기존 연구의 문제점인 TCF와 EF를 고려하지 않고 직접 UUCP로부터 개발 노력을 추정한 수 있는 선형, 로그형, 다항식, 거듭제곱 및 지수함수 회귀모델의 성능을 평가한 결과, 가장 적합한 모델로 지수형태의 비선형 회귀모델을 도출하였다.

The purpose of this study is to develop the growth prediction model that can predict growth and development information influencing on the production of citrus fruits. The growth model was developed to predict the floral leaf ratio, number of fruit sets, fruit width, and overweight fruits depending on the main period of growth and development by considering the weather factors because the fruit production is influenced by weather depending on the growth and development period. To predict the outdoor-grown citrus fruit production, the investigation result for the standard farms is used as the basic data; in this study, we also understood that the influence of weather factors on the citrus fruit production based on the data from 2004 to 2013 of the outdoor-grown citrus fruit observation report in which the standard farms were targeted by the Agricultural Research Service and suggested the growth and development information prediction model with the weather information as an independent variable to build the observation model. The growth and development model for outdoor-grown citrus fruits was assumed by using the Ordinary Least Square method (OLS), and the developed growth prediction model can make a prediction in advance with the weather factors prior to the observation investigation for the citrus fruit production. To predict the growth and development information of the production of citrus fruits having a great ripple effect as a representative crop in Jeju agriculture, the prediction result regarding the production applying the weather factors depending on growth and development period could be applied usefully.

This study investigated applicability of the fast running model for damage assessment of underground structures by ground shock. For this reason, the fast running model that consists of two main models such as the ground shock generation and propagation model and the underground structural damage assessment model was developed. The ground shock generation and propagation model was programed using theoretical formula and empirical formula introduced in TM5-855-1(US army manual). The single degree of freedom model of structural components was utilized to predict structural dynamic displacements which are used as index to assess damage level of components. In order to confirm the feasibility of the developed fast running model, underground structural dynamic displacements estimated from the fast running model were compared to displacements obtained from the finite element analysis.

While there are many successful cases where application of the TQM model has reaped substantial benefits (Corcoran, 1996; Hayday, 1996 and Massey, 1996), there is little attempt to further develop the TQM model to meet organisations' development needs. The purpose of this paper is introduce the process of development of a fit-for-purpose management system model to meet the development needs of the MTR Corporation Limited, a metro company of Hong Kong. The new management system model is formulated based on the previous research results, on TQM but comprises a new approach to bridging their pitfalls. The formulation of the TMS elements is based on the common factors of four National Quality Awards (Japan, USA, Europe and Australia) and the critical factors developed by seven studies. These studies include those of Saraph et al. (1989), Flynn et al. (1994), Anderson et al. (1995), Powell (1995), Handfield and Ghosh (1995), Black and Porter (1996), and Ahire et al. (1996).
