Purpose: Traditionally, information technology acceptance have been considered one of the most important research issues. However non-acceptance, which was main objective of acceptance theories, have not been included in main research area by communities of information systems. This study is to identify the factors influencing non-acceptance of information technology and suggest a total research model for explaining the phenomena of non-acceptance. Design/methodology/approach: Grounded theory was adopted as a principal research method. which is an inductive technique of interpreting qualitative data about a social phenomenon to build theories about that phenomenon. Data were collected by depth interview and open question on potential non-adopters during 3 months. The collected data were coded by two main coding paradigm in ground theory, open coding and axis coding. Findings: Factors influencing non-acceptance, status quo, imitation, value evaluation, and concerning risk were extracted from open coding. These factors were integrated into system 1 thinking and system 2 thinking, which were from axis coding. More specifically, status quo and imitation are system 1 thinking which are more responsive and emotional thinking and value evaluation and concerning risk are system 2 thinking which are more rational and reasoning thinking.

Objectives Syndrome differentiation and treatment (辨證論治) was one of the core theories in Korean medicine and syndrome differentiation (辨證) constitutes a branch of disease diagnosis in Korean medicine. Yoon Gil-Young, one of the modern outstanding scholar of basic medical science in Korean medicine, wrote on basic theories of Korean medicine such as physiology, pathology, formula science, etc. Hereby we will analyze and discuss his works to understand his recognition of historical changes in the syndrome differentiation. Methods We conducted researches into the two works of Yoon Gil-Young's, which are "The Clinical Formula Science of Eastern Medicine (東醫臨床方劑學)" and "The theory of Four-Constitution Medicine (四象體質醫學論)". From Yoon's academic standpoint which connects the basic medical science with the clinical medicine, we analyzed his opinion about the system in the Theory of 'Syndrome Differentiation'. Results According to Yoon's research work on the Theory of 'Syndrome Differentiation', the system of syndrome differentiation, which had its deep root in the theory of Yin and Yang (陰陽) & the theory of abbreviation of the five circuit phases (五運) and the six atomspheric influences (六氣) of the "Huangdi's Internal Classic (黃帝內經)". Conclusions Yoon Gil-Young's theory of differentiation of syndromes and treatment is widespread so much that he studied on the learning field of Traditional Korean Mediciine and ingenious as well. He explain on the main principles of differentiation of syndromes based on "Huang Di Nei Jing" and the system of differentiation of syndromes is composed of Traditional Korean Medical Physiology.

이 연구는 루만의 체계 이론을 통해, 2013년 12월에 발생한 '안녕들 하십니까?(이하 안녕들)' 현상을 분석했다. 루만에 따르면 커뮤니케이션은 타아에 의해 선택된 정보와 선택된 전달을 자아가 선택적으로 이해함으로써 시작하고 성립된다. 이때 이해는 내용의 수용과는 별개로, 그것은 후속 커뮤니케이션의 쟁점이다. 이처럼 선택을 토대로 한 커뮤니케이션의 설명은 안녕들 현상에 잘 적용되며, 아울러 커뮤니케이션에 대한 해석을 심화시킨다. 특히 안녕들 현상이 가져오는 후속 커뮤니케이션의 파생에 대한 해석을 위해 루만의 커뮤니케이션 이론은 적절하다. 안녕들 현상은 '안녕하지 못한 정치'에 대해 특정한 의미를 발생시키며 후속 커뮤니케이션을 지속적으로 유발하는 자기 생산적 체계다. 아울러 반박 대자보나 심지어 대자보 훼손 행위도 안녕들 현상이 발생시킨 '안녕하지 못한 정치'에 대한 부정을 야기하는데, 이 또한 커뮤니케이션의 중요한 요소다. 따라서 대자보는 안녕들 체계의 '안녕하지 않음'을 상징적으로 일반화한다고 볼 수 있다. 그래서 대자보 훼손은 안녕들 체계와는 근본적으로 구별되는 커뮤니케이션으로 관찰될 수 있다. 안녕들 체계는 대자보를 통해 사회에 더 나아간 커뮤니케이션을 시도하고 후속 커뮤니케이션을 기대한다.

This paper presents the general system theory and its applications to the safety analysis method that is a recent trend over the traditional event-driven model. This new model is known as STAMP(Systems Theory Accident Modeling and Process)proposed by Nancy G. Leveson in MIT. The new model has benefits of systemic approaches concerning the system safety as a whole including the context it is in, its stimulants and outcomes, and its parts as well as the relationships among them in a holistic manner. The method consists of a hierarchical control structure, a process model, and the safety constraints governing the control. This paper demonstrates an example the contrasts the differences between the approaches of STAMP and the traditional safety models.

This paper describes the application of discrete event systems theory to the design of an automated laboratory system. Current automated laboratory systems typically consist of several interacting processes that must be carefully sequenced to avoid any possible process conflicts. Discrete Event Systems (DES) theory and Supervisory Control Theory (SCT) can be applied together as effective methods of modeling the system dynamics and designing supervisory controllers to precisely sequence the many processes that such systems might involve. Classical approaches to supervisory controller design tend to result in complex controller structures that are difficult to implement, maintain, and upgrade. In this paper, a new approach to designing supervisory controllers for automated laboratory systems is introduced. This new approach uses a modular controller structure that is easier to implement, maintain, and upgrade, and deals with "state explosion" issues in a novel and efficient way.

This paper presents a new state feedback control approach for communication networks based control systems in which control input and output observation time-delay natures are generally occurred in practice. We first establish a generic state feedback control framework based on well-known linear system theory. A maximum time-delay value which allows critical stability of whole control system are defined to make a positive definite Lyapunov function which is mathematically composed of controlled system states. We analytically derive its control parameters by using a steepest descent optimization method in order to guarantee a stability condition through Lyapunov theory. Computer simulation is numerically carried out for demonstrating reliability of the proposed NCS algorithm and a comparative study is accomplished to prove its superiority for which the traditional control approach for NCS is made use of under same simulation scenarios.

Most of solution methods in scheduling attempt to generate good solutions by either developing algorithms or heuristic rules. However, scheduling problems in the real world require considering more factors such as multiple objectives, different combinations of heuristic rules due to problem characteristics. In this respect, the traditional mathematical a, pp.oach showed limited performance so that new a, pp.oaches need to be developed. Expert system is one of them. When an expert system is developed for scheduling one of the most difficult processes faced could be knowledge acquisition on scheduling heuristics. In this paper we propose a method for the acquisition of knowledge on the selection of scheduling heuristics using Dempster-Shafer Theory(DST). We also show the examples in the multi-objectives environment.

This paper revisited the key advances on System Dynamics modeling about traditional macro-economic models and economic growth structures, and then tries to elaborate a new model based on the endogenous growth theory that incorporates new growth factors, relevant to knowledge/technology as well as the Environment, into traditional growth models. Accordingly, the new model augments the acceleration and multiplier loops and the balancing ones representing market clearing mechanism with a simple numerical example. The authors thus provides macroeconomic System Dynamics analysts with a milestone to model macro-economic structures reflecting on traditional and cutting-edge theories on sustainable economic growth and general equilibrium modeling.

본 연구에서는 전후 선진국을 중심으로 이루어진 기술혁신정책의 기조변화와 그것을 반영하고 또 선도하는 기술혁신이론의 전환을 살펴보았다. 1980-90년대를 전후해서 등장한 새로운 기술혁신정책의 기조는 사용자 지향성의 강화, 임무지향성에서 경제 사회 지향성으로의 전환, 능력의 향상 등으로 요약될 수 있다. 한편 정책기조의 이와 같은 변화는 혁신체제론을 통해 기술혁신이론에 반영되었다. 상호작용적 학습과 혁신능력을 중심으로 논의를 전개하고 있는 혁신체제론은 이러한 기술혁신정책의 변화를 이론체계 내에 상당부분 수용하였다. 그러나 최근 기술혁신정책에서 강조되고 있는 사회적 측면들은 아직까지 혁신체제론에서 본격적으로 다루어지지 않고 있다. 이 글에서는 향후 혁신체제론의 중요한 연구과제 중의 하나를 '사회'를 이론체계 속에 포괄하는 것으로 파악하고 그러한 작업을 위한 출발점이 될 수 있는 논의를 다루었다.
