Purpose: The purpose of this study was to propose useful suggestions by analyzing the causal relationship between technology-based self-service for smart airport and intention to use. Methods: The data was collected by using the structured questionnaires. The proposed research model is tested using 231 valid questionnaires by R.3.2.1 plspm package. Results: The results of this study are as follows; the effecting factors of technology based self service for introducing smart airport, it was found that the effects of personal innovativeness and enjoyment and responsiveness, social impact were significant for acceptance and personal innovativeness was not significant on perceived usefulness. This study suggests significant factors on the implementation of smart airports and technology-based self-service. It also introduced new technologies in the future by looking at various characteristic factors that affect the intention of using technology-based self-service to promote smart airports. Conclusion: Airports and aviation industries need to have easy access to the airport's technology-based self-services to build a successful smart airport and create an environment that can be used appropriately at the time the customer wants. Also when customers use technology-based self-service devices, they should consider to maximize the positive emotions (emotional values such as pleasure or fun) that customers feel.

The PERT/CPM are considered as the base procedures for the most successful project scheduling programs. Unfortunately, it is not easy to apply these procedures to real-life projects. This is due to the fact that PERT/CPM assume an infinite number of resources for each activity in project networks. Obviously, the completion time under no constraints is less than when constraints are imposed. One way of approaching this problem is to use heuristic solution techniques. In this paper, we present three heuristics; MRU (Maximum Resource Use) rule, STU (Shortest Time Use) rule, MRUP (Max Resource Use and Period) rule for allocating resources to activities of projects under multiple resource constraints. Comparisons of the project durations show that these heuristic rules are superior to AG3 rule that has been widely used in practice (Elsayed and Boucher, 1994).

An intelligent road transport management system focused on microscopic, real-time traffic signal control is proposed. Referring to the development of those systems in Japan, extensive use of image traffic detectors observing the movement of vehicles inside intersections, and direct data exchange between the signal controllers of neighboring intersections are newly assumed. On site investigation of five intersections in Japan or in Malaysia shows the possibility of effective information provision and simple algorithm for solving heavy congestion, as well as easy installation.

본 연구는 만성질환 환자들의 건강상태나 건강행위에 영향을 미치는 원격진료의 수용행위를 체계적으로 규명하고자 하였다. 이를 위해 2013년 강원도지역에서 원격진료를 받고 있는 210명의 고령층 만성질환자들을 대상으로 설문조사를 실시하고 구조방정식 모델을 통해서 수용성에 미치는 영향요인을 검증하였다. 연구결과 첫째, 원격진료에 대한 지각된 유용성은 지속적인 원격진료 이용의도에 유의미한 영향을 미쳤으며, 지각된 사용용이성 역시 원격진료 이용의도에 유의미한 영향을 미치는 것으로 나타났다. 둘째로 원격진료에 대해 주변사람들의 주관적 인식이 관대하고 긍정적일수록 원격진료에 대한 사용용이성과 유용성에 더 긍정적인 것으로 나타났다. 셋째로 원격진료에 대한 신뢰 역시 정보수용과정에서 정보의 질적 수준이 정보의 활용경험과 유용성에 영향을 미친다는 기존의 연구와 일치하는 결과를 보여주었다. 마지막으로 건강에 대한 외적 통제소재는 지각된 유용성에 긍정적으로 영향을 미치는 것으로 확인되었다. 이 연구는 지역사회 원격진료의 수용을 구조적으로 검증함으로써 모델의 정교화에 기여하고 있다.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

기술 발전에 따른 착용형 단말의 기능들은 더 다양하고 복잡해지고 있다. 복잡한 기능 때문에 일반 사용자들도 기능을 사용하기 힘든 경우가 있다. 본 논문에서는 사용자에게 편리하고 간단한 인터페이스 방식을 제공하자는데 목적을 두고 있다. 음성 인식의 경우 사용자 입장에서 직관적이고 사용하기 편리할 뿐만 아니라 다양한 명령어를 입력할 수 있다. 하지만 음성 인식을 착용형 단말에서 사용할 경우 컴퓨팅 파워라든지 소모전력 등 하드웨어적인 제약이 있다. 또한 착용형 단말은 언제 사용자가 음성으로 명령을 내릴지 그 시점을 알 수가 없다. 따라서 명령을 입력 받기 위해서는 음성 인식이 항상 동작하여야 한다. 하지만 소모전력 문제 때문에 이와 같은 방법을 사용하기에는 무리가 있다. 음성 인식이 가지고 있는 문제점을 보완하기 위해 제스처 인식을 사용한다. 본 논문에서는 음성과 제스처를 혼합한 멀티 모달 인터페이스로 사용자에게 어떻게 편리한 인터페이스를 제공할 것인지에 대해 설명하고 있다.

Numerous solution methods for scheduling problems such as part dispatching problem, operation sequence problem have been suggested as a means to be embedded in hierarchical or centralized shop floor control. Under the preceding control philosophies, however, response to changes in the shop floor status is quite slow and timely decision is sometimes impossible. Moreover, the control software becomes too large and it is almost impossible to modify the control software when the configuration of the shop floor changes. In agile manufacturing which emerged recently to cope with quick response and easy modifiability when unexpected changes occur, a new control policy is needed. CSCW[Computer Supported Cooperative Work] based shop floor control casts a different view on scheduling problems. Decisions are made locally when requested and useful information is scattered among agents for its efficient use. Adaptation is easy because agents are -'plug compatible or portable. In this paper, scheduling problems occurring under CSCW based shop floor control are identified and characterized. Traditional scheduling problems are reviewed from the CSCW viewpoint. All the control entities involved in the shop floor can be found and used to defined agents. With these entities and CSCW concept, possible scheduling problems are identified.

In order to achieve the best performance, the automatic control with advanced technology is made of sheathed steel to withstand a wide range of wave loads. This model shows how to control the vibration of the fiber panel as a solution using the new results from the Lyapunov stability question, a modification of the bat that making it easy to calculate and easy to use. It is used to reduce the storage space required in this system. The results show that the planned worker can compensate effectively for the unplanned delay. The results show that the proposed controller can compensate for delays and errors. Fuzzy control (predictive control) demonstrated the external vibration can be reduced.

The purpose of this study was to confirm multiple retention system of C-PAM, A-PAM and Inorganic micro particles vs. traditional micro particle system and dual polymer system by measuring retention, drainage and formation using RDA HSF and Techpap 2D -F Sensor The benefits of dual polymer system were easy to use, low chemical consumption and good retention property but defect was worse drainage property than inorganic microparticle systems. On the other hand, Inorganic microparticle system had benefit of good drainage effect but defects were difficult to use, high chemical consumption. Therefore, we tried to find optimal morphology of polyacrylamide and applied to multiple retention system of C-PAM, A-PAM and inorganic microparticles to compensate defects of both of retention systems. As a result, we found the performance of branched C-PAM, branched A-PAM and inorganic micro particle triple system was more appropriate than traditional inorganic mircoparticle systems or dual polymer systems by comparing retention, drainage and formation.
