The electrical and the optical properties of organic light-emitting devices (OLEDs), with and without various kinds of multiple heterostructures were investigated. The efficiency in green OLEDs were significantly enhanced by the structure of the multiple heterostructures acting as a hole transport layer (HTL) rather than by the number of periods. These results indicate that highly efficient green OLEDs utilizing multiple heterostructures acting as a HTL can be fabricated.

Recently, automobile industry expands from mechatronics area through intelligent information area, and the telematics technology is one of the greatest developing points. The telematics is utilizing the on-board-unit of vehicle's communication system, and it provides necessary information and value-added service to vehicles as well as drivers. Most of the telematics offers the solution of searching a route or generates an optimal path. This paper investigates telematics with the logistics point of view, such as freight location tracking, vehicle emergency information, etc. The telematics is a core technology of automobile industry, and it becomes new business paradigm of IP(information provider). Especially, ETA(estimated arrival time) of freight and distribution tracing information are critical issues in the logistics industry. The successful integration with telematics is introduced in the paper.

This paper proposes a finger crease pattern identification algorithm utilizing a clustering method. The algorithms has been developed for the use of biometric person identification system. Since the finger crease pattern may be well-imaged utilizing low cost imaging devices such as low-end CCD camera with LED lighting, the feasibility of commercialization of the algorithm and the system utilizing the algorithm may be well justified if the finger crease pattern is a reasonable choice for the biometric feature. In this paper, we exploit this possibility and show the potential of using the finger crease pattern as a feature for biometric person identification.

본 연구는 2015 개정 수학과 교육과정에서 강조하는 수학 교과 역량 중 하나인 정보 처리 능력의 하위요소별로, 현행 2009 개정교육과정에 따른 수학교과서와 익힘책의 통계 내용을 분석하였다. 그 결과 '자료와 정보 정리 및 분석'에 해당하는 내용이 '자료와 정보 수집', '정보 해석 및 활용', '공학적 도구 및 교구 활용'에 비해 월등히 많았다. 자료와 정보 수집은 자료 수집의 범위가 좁은 저학년에 많이 제시되어 있었고 자료 수집 방법에 대한 탐구가 부족하였다. 정보 해석 및 활용 또한 자료로부터 해석하기를 토대로 정보 활용이 이루어지지 않은 부분이 있었으며, 공학적 도구 및 교구의 활용은 지도서에 안내하는 정도로 교과서에 거의 제시되지 못했다. 이러한 연구 결과를 바탕으로 정보 처리 능력을 함양하는데 도움이 될 수 있도록 자료와 가능성 영역 초등 수학교과서 개발에 대한 시사점을 제공하고자 한다.

The current companion animal registration system is based on implanting microchip into animal body. Thus, the maintenance cost is high, and it may cause dangerous effect on the animal health. Moreover, it is very inconvenient in utilizing the information. This paper presents a pet registration and information providing system based on QR code for low cost and convenience in field application. The owner can simply register pet information on the web server, print the QR code and attach it to the pet. Any person can scan the QR code by smart phone, identify the information, and call the owner directly.

In a situation that building energy consumption is increasing worldwide, the research utilizing BIM technology to analyze building energy has been actively conducted. On the other hand, data input method of the building energy analysis has been still manually entered. This paper proposed a improved input method of required information for building energy analysis using the ECO2-OD program. As a result, although some required information of BIM based design software could be almost entered when it comes to general information and architectural sector, it has a problem to be handled in HVAC sector. Therefore, in the both of general and architectural sectors, the BIM information from the BIM-based design software could be directly used to automatically and systematically input the information. Future research should be studied the algorism and method in connection with data exchange to utilize input method of ECO2-OD from BIM data.

Procedures play a key role in ensuring safe operation at nuclear power plants (NPPs). Development and maintenance of a large number of procedures reflecting the best knowledge available in all relevant areas is a complex job. This paper introduces a newly developed methodology and the implemented software, called iExtractor, for the extraction of syntactic and semantic information from NPP procedures utilizing natural language processing (NLP)-based technologies. The steps of the iExtractor integrated with sets of rules and an ontology for NPPs are described in detail with examples. Case study results of the iExtractor applied to selected procedures of a U.S. commercial NPP are also introduced. It is shown that the iExtractor can provide overall comprehension of the analyzed procedures and indicate parts of procedures that need improvement. The rich information extracted from procedures could be further utilized as a basis for their enhanced management.

This study is based on education reforms related to strengthening information education in curriculums. This study develops and presents ' General Economics'Model Utilizing ICT(Information Communication & Technology) in Home Economics'which could be used as a concrete guidance and direction in teaching and learning Economics education in schools. To do so, this study reviews the necessity of adopting ICT in Home Economics instructional activities and it also reviews and analyzes previous studies of how ICT contribute to instructional activities. Such analysis was used as a theoretical basis for the Instructional Model. The Tool of ICT is a useful instructional strategy because it allows the learners'self-lead learning and Performance Assessment. Therefore the 'General Instructional Model Utilizing ICT'interprets the role of ICT tools to adequate class activities in each step of instruction which includes the conventional steps of introduction. development review and evaluation. It also develops and presents Lesson Plan that can be adopted in school education and thereby shows the possibility of practical application of the theory. This study has limits in that the Instructional Model and Lesson Plan are theoretical in nature. Therefore, in future studies it is desirable to critically review the Instructional Model an Lesson Plan and prove their applicability in real classes and the real learning effects.

Objectives: The aim of this survey was to investigate utilization, intended use, problems with and demand for medical devices by surveying members of the traditional Korean medical society. Methods: We distributed questionnaires to 13,957 traditional Korean medical doctors via e-mail, and received replies from 1,225. The questionnaire consisted of 4 multiple-choice questions for survey respondent information, 8 multiple-choice questions about the status of medical devices utilizing, and a short answer question about the demand for medical devices. Results: Use of medical devices in traditional Korean medical clinics is common. Diagnostic medical devices are mainly used to assess the patient's condition and to establish a close rapport with clients. In case of therapeutic medical devices, they are usually used for secondary treatment. Issues with traditional Korean medical devices currently in use were ineligibility for national health insurance, low reliability, uncertain validity, and high price. In development of traditional Korean medical equipment, the need for diagnostic medical devices was greater than for therapeutic, and the need for the recording and analysis of medical image data and visualization of medical information was great. Conclusions: There is growing demand for facilitating the development and commercialization of traditional Korean medical devices. To satisfy this demand, research on evaluation indicators that reflect functional and structural clinical information and how to clinically assess the indicators should proceed.
