The significant role of transportation system for economic development process has been recognized, but the argument that transportation improvements stimulate economic development has brought sometimes no resonance in lacking of a plausible theory on the conditions and process of economic development by transportation investment. This paper reviews the theory on regional differentiation of transportation system and shows why and how the installation of a new transportation system or the improvements of the old transportation quality differentiate the spatial order of economic activities. It presents the interaction between the change of transportation quality with introducing of definition "transportation value" as tool of its determination and economic activities following the regional differentiation process, which result means regional defferentiation of niveau of economic development.

본 논문은 BPM 시스템에 의해서 관리되는 비즈니스 프로세스의 효율성을 증대시키는 새로운 방법으로 TOC(Theory Of Constraint)이론에서 사용되는 DBR(Drum, Buffer, Rope) 개념을 적용한다. TOC이론은 주로 생산공정의 효율증대를 위한 방법론으로 인식되어 왔지만 비즈니스 프로세스에서도 적용이 되도록 BP-DBR (Business Process - DBR) 방법론을 개발한다. 또한 이를 통해 실제 금융권에서 사용되는 프로세스 효율성이 증대되는 것을 시뮬레이션 실험을 통해 보인다.

Purpose: The purpose of this study was to understand the coping process that family caregivers experience during the process of care, to grasp coping behaviors used to solve problems and, finally, to develop a substantive theory by analyzing the coping process. Method: The methodology of collecting and analyzing data used in this study followed the ground theory of Strauss and Corbin(1998). Data were collected through in-depth interviews with open-ended and descriptive questions about the subjects' coping experiences, which were audio-taped and transcribed. The survey was conducted between February 2000 and February 2001. The subjects of this study were 17 women. Result: The result of the study is as follows. The coping process of family caregivers while taking care of the demented elderly was found to have six stages: problem recognition: undertaking care: struggling: mental control: burden mediation; and acceptance. These stages proceed with reciprocal action and in cycle. Conclusion: The result of this study is helpful for developing effective and individual nursing strategies suitable for each coping stage. It is necessary to develop an assessment tool that can judge caregivers' coping stage based on the result of this study. Moreover, we need continuous study to practice nursing mediation and to analyze the change about nursing effect and family members' adaptation.

The integrated core network architecture and various mobile subscriber behavior can result in a significant increase of signaling load inside the evolved packet core network proposed by 3GPP in Release 8. Consequently, an authentication signaling analysis can provide insights into reducing the authentication signaling loads and latency, satisfying the quality-of-experience. In this paper, we evaluate the signaling loads in the EPS architecture via analytical modeling based on the renewal process theory. The renewal process theory works well, irrespective of a specific random process (i.e. Poisson). This paper considers various subscribers patterns in terms of call arrival rate, mobility, subscriber's preference and operational policy. Numerical results are illustrated to show the interactions between the parameters and the performance metrics. The sensitivity of vertical handover performance and the effects of heavy-tail process are also discussed.

Purpose: The purpose of this study was to discover the recovery process of those having had myocardial infarction. Methods: 15 participants with myocardial infarction were recruited by theoretical sampling methods. The data were retrieved through in depth interview, participant observation, and medical records of the patients. Collected data were analyzed through grounded theory approach of Strauss and Corbin(1998). Results: 63 concepts, 27 subcategories, and 11 categories were deduced from the open coding process. The recovery process of myocardial infarction showed to be a process of 'Controling healthy track', and chronological recovery process was a four-step process of recognizing disruption of healthy track, making efforts for controlling the disrupted healthy track, reconstructing the new healthy track, and adapting to the new healthy track phase. 'Controling healthy track' had three types of self-initiation, contention of reality, and fateful acceptance. Conclusion: The results provided basic information for nursing intervention strategies depending on 'Controling healthy track' process by each phase and different types.

Science and technology are regarded as public goods and knowledge in traditional innovation theory. Also, linear innovation model and technological determinism are derived from its theory. This is changed, however, in new innovation theory. Social shaping of technology is emphasized and interaction, network, system characters of innovation process are involved in its theory.

The escape theory is the theory of problem behavior such as suicide. The purpose of this study is to investigate the causes of gaming disorder, which has been attracting attention as a typical youth problem, through escape theory. Suicide theory is a process in which the problem triggered by the negative external environment flows into internal attribution and self-criticism, and this leads to a process leading to problematic behavior with disgust self-awareness. This process was applied to the environment, psychology, and behavior of adolescents. As a result, the lack of affection and consistency of the parents resulted in negative external environment, which affected the self-esteem of children by creating a negative external environment. And low self-esteem caused negative emotions, lowered self control, and confirmed to induce game addiction. The results of this analysis show that game addiction has a structure similar to obsessive behaviors such as binge eating and shopping addiction explained through the escape theory model and it is necessary to concentrate more on the environmental psychological factors for game addiction research.

The purpose of this study was to discover a conceptual framework and evaluation process of apparel quality by means-end chain theory. The theoretical study was conducted to find out a conceptual framework and build a hypothetical evaluation process model of apparel quality. Apparel quality was perceived associative network called a means-end chain and was evaluated in several stages. A conceptual framework of apparel quality evaluation was organized into hierarchical relationships among four different dimensions: physical attribute, physical function, instrumental performance, and expressive performance. The means-end structure linked tangible physical attributes and function to more abstract instrumental and expressive performance. A hypothetical evaluation process model linked dimensions of apparel quality to the selected means-end relationship. Different consumers had different means-end chains for the same apparel. Therefore different subjects are likely to have different evaluation paths. From this study we can suggest an evaluation process model of apparel quality.

In this paper, we proposed the intelligent navigation agent model for successive electronic commerce system management. Fuzzy theory is very useful method where keywords have vague conditions and system must process that conditions. So, using fuzzy theory, we proposed the model that can process the vague keywords effectively. Through the this, we verified that we can get the more appropriate navigation result than any other crisp retrieval keywords condition.

The study aims to explore the nature, drivers of BAE. In particular, how and why consumers engage with branded mobile apps. Since consumer engagement is a multi-dimensional and complex phenomenon, the authors took an interpretivist paradigm and used a grounded theory approach by interviewing 24 participants. The findings reveal that branded app engagement (BAE) is triggered by mainly three aspects, i.e., media characteristics (Privacy and security, customization, and convenience), brand-related aspects (brand image and product/service quality), and benefits sought (inherent and derived). More importantly, we uncover the underlying mechanism for each factor. Furthermore, the study explains the BAE process in its entirety from an app-centric perspective rather the brand powering the app. Thus, the study offers a fresh perspective and novel insights into the BAE process.
