Purpose: The study aimed to design and develop an automated personalized self-care (APSC) program for patients with type 2 diabetes mellitus. The secondary aim was to present a clinical protocol as a mixed-method research to test the program effects. Methods: The APSC program was developed in the order of analysis, design, implementation, and evaluation according to the software development life cycle, and was guided by the self-regulatory theory. The content validity, heuristics, and usability of the program were verified by experts and patients with type 2 diabetes mellitus. Results: The APSC program was developed based on goal setting, education, monitoring, and feedback components corresponding to the phases of forethought, performance/volitional control, and self-reflection of self-regulatory theory. Using the mobile application, the participants are able to learn from educational materials, monitor their health behaviors, receive weekly-automated personalized goals and feedback messages, and use an automated conversation system to solve the problems related to self-care. The ongoing two-year study utilizes a mixed method design, with 180 patients having type 2 diabetes mellitus randomized to receive either the intervention or usual care. The participants will be reviewed for self-care self-efficacy, health behaviors, and health outcomes at 6, 12, 18, and 24 months. Participants in the intervention group will be interviewed about their experiences. Conclusion: The APSC program can serve as an effective tool for facilitating diabetes health behaviors by improving patients' self-care self-efficacy and self-regulation for self-care. However, the clinical effectiveness of this program requires further investigation.

The purposes of this study were to suggest 1) a future direction for Korea's machine tool industry and 2) how to secure the safety and reliability of emerging intelligent or automated machine tooling. The study concludes that, overseas, the machine tool industry is growing again while promoting innovation by converging with ICT. Accordingly, Korea also promotes ICT innovation to advance the machine tool industry, which is at the core of the national economy. As a result, unlike in the past, the frequency of serious injuries like entrapment accidents has recently decreased, while the proportion of collision accidents has increased. In addition, a new type of accident has become possible. Since ICT is network-based, the distinction between work and rest can become ambiguous; there is a risk of hacking, working hours and places are flexible and there are risk factors for diseases like chronic fatigue due to overload of specific personnel. As robots and automation are introduced, there is also a high probability of problems caused by physical and psychological burdens on system operators and resulting fatigue.

This paper presents a Petri net approach for the control and monitoring of discrete event system. The proposed model is fuzzy Petri nets based on the fuzzy logic with Petri nets and the hierarchy concept. Fuzzy Petri nets have been used to model the imprecise situations which can arise within automated manufacturing system, and also the hierarchy concept allow to handle the refinement of places and transition in Petri nets model. These will form the foundation of a simulator-tool with manipulation interface for application of fuzzy Petri nets.

국내에서도 정보시스템 보안관리가 체계화되면서 보안컨설팅 분야가 중요한 분야로 대두되고 있다. 보안관리에서 핵심부문인 위험분석에 대한 연구는 진행되어 왔으나 국내환경에 적용하기 어려운 점이 많았다. 특히 정보시스템에 대한 분석기준과 정량화가 전무한 국내에서 외국산 위험분석 도구 등을 이용한 분석결과가 객관성을 갖기가 매우 어렵다. 따라서 위험분석 자동화 분석도구의 개발과 적용을 통하여 이러한 문제점을 고찰하고 국내 환경에서 위험분석을 실시할 수 있는 환경을 위하여 필요한 해결방안을 살펴보았다.

In the industrial field nowadays the information that needs to be handled arc increasing and requires faster speed in contrast with PLC(Programmable Logic Controller) or DCS(Distributed Control System) based control systems these days. The work environment these days are mostly based on PC, so the control systems are wanted in PC. At Fieldbus used automated systems performing distributed process control by PC performs and combines into one system in order to maximize the increase of productivity, lower the expense, planning constructing and maintaining the reliance of automation. These latest automation systems unites process, makes distributed control process able, and can control and supervise at remote PC.

This study considers flowshop scheduling problem related to flexible maufacturing cell in which consists of two machining centers, robots for loading/unloading, and an automated guided vehicle(AGV) for material handling between two machining centers. Because no machinng center has buffer storage for work in process, a machining center can not release a finished job until the empty AGV is available at that machining center. While the AGV cannot tranfer an unfinished job to a machining center until the machining center empty. In this paper, an new heuristic algorithm is given to find the sequence that minimize their makespan.

Optokinetic nystagmus(OKN) testing is an useful tool for assessment of human visual function. Specially, this method has been used for assessing visual function in infants and malingering patients. OKN drum and OKN tape are the common devices currently used for clinical cases. In this paper, we present newly the automated and computerized method for the quantitative and objective assessment of visual acuity in OKN testing.

In this paper, we developed an automated program for the modeling and manufacturing of three-dimensional roller gear cams. A computer program employing the theory of gearing and coordinate transformation is developed for synthesizing and animating cam mechanisms. A method using wire frame modeling and shading by triangular element is presented, and effectively used for modeling of example with reduced computation time. Then a module for generation NC program a five-axis CNC machine to manufacture roller gear cam is established.

Today, manufacturing market is highly competitive due to more complex and variable products, shorter delivery lead times, intensified product development rate, customers's increasing concern about quality, durability, maintainability, safety and environmental performance. To survive this environment, development of the automated design system is needed using AutoCAD. This paper represents a computer aided design system for watergate by using AutoCAD R2000 system and its Visual LISP computer language. The developed system ultimately generates the design for water gate through AutoCAD.

It is a time-consuming work to develop a control software for AGVS considering different physical arrangements and transport requirements in automated manufacturing systems. An integrated software environment is suggested to support the development of the control software by utilizing a simulation software which imitates changes in the target shop floor. First, the basic functions of the controller are defined and interactions between modules(function) are identified to enhance the modularity of the controller. Prototype software is developed for the simulation station and the control station, respectively, which are connected with each other by a communication link to transmit predefined messages.
