The purpose of this study is to investigate the causality between life satisfaction and domain satisfactions. For this study, data were collected from 207 respondents. They completed World Health Organization Quality of Life Assessment Instrument - Brief (WHOQOL-BREF) which is self-report questionnaire asking about life satisfaction and domain satisfactions. For data analysis, the verification procedure by autoregressive crosslagged modeling of structural equation was used. The analysis results of measures showed the causal relation between the two variables, that is, domain satisfactions acted as cause of life satisfaction. There were discussions on the issues about the analysis method of the autoregressive crosslagged modeling, the implications of the results, and the limits of the research. This study ascertained the intervention direction between life satisfaction and domain satisfactions to promote life satisfaction.

In the process of presenting the additional criteria, ISST, developed to evaluate teachers' capacity of applying information, suggests the criteria without considering teacher's own task. Information Ethics and Security Model is made up of two parts. In one part, it deals with four areas concerning with Information Ethics evaluation to measure the sensibility of Information Ethics of Information Teacher In another part, it is divided Information Security Evaluation into three areas which estimate technical method to secure the information system tying in the environment of information-oriented education.

Computers are played an important tole of knowledge-information society in 21C. Computer education have made successful progresses since the 7th curricula have one class of ICT per week. However, public schools have instructed computer literacy education teaching only how to use application software. To give useful knowledges students could use for several decades, we need to have them to concentrate on education to information logical thinking power rather than simple manipulation of application softwares. However, teachers don't understand well about the "Understanding of Information Processing". In this paper, we carried out a survey that how much teachers understand about the information processing comprehension among the information and communication technology guide. We also state problems and propose improvement plan.

To restore image degraded by out-of-focus blur and additive noise, an iterative restoration is used. Acceleration parameter is usually applied equally to all over the image without considering the local characteristics of degraded images. As a result, the conventional methods are not effective in restoring severely degraded edge region and shows slow convergence rate. To solve this problem we propose an adaptive iterative restoration according to local degradation, in which the acceleration parameter has low value in flat region that is less degraded and high value in edge region that is more degraded. Through experiments, we verified that the proposed method showed better results with fast convergence rate, showed Visually better image in edge region and lower MSE than the conventional methods.

The purpose of this study is to analyze academic research trends of the library management in Korea. Especially, this study focused on research trend analysis according to the sub categories of library management. For this purpose, this study analyzed a total of 359 papers of library and information science from 2004 to 2013 at the four academic journals of the National Research Foundation of Korea. As a result, it was found that the sub field which showed the highest performance was 'general management' and following sub fields were 'measurement and evaluation', 'human resource management', 'building and facility', 'policy and system.' However, there has been relatively less performance in the sub fields like 'marketing', 'organization management', 'budget management'.

An optical fiber displacement sensor has the advantages of relatively simplicity, cheap, small probe size and immunity against environmental perturbation. The working principle of the sensor is based on the intensity modulation that is detection light intensity reflecting from the surface being measured. This paper presents the mathematical model of displacement measurement mechanism of this sensor type. The theoretical and experimental data are compared to verify the model in describing the realistic approach to sensor design. Finally, the analysis results show that displacement response characteristics such as sensitivity, measuring range are easily modified by principal design parameters such as magnitude of optical Power, diameter of optical fiber core and distance between transmitting fiber and receiving fiber.

We investigated visible light radiated from Plasma Focus device by time-integrated analyzed method. Plasma focus is a device that translated from electric energy into visible light by electric discharge. Spectral analysis is using Monochromator(focal length = 0.5 m). Time-integrated spectrum is analyzed with densitometer the film which developed a constant range of wavelength. The condition of visible emission was that the discharging voltage was 13 kV and the working gas were Argon and Helium.

In this study, educational service programs of archives have been reviewed through articles and case studies. As a result, five main educational services of archives were found. First, educational services are provided to K-12 students and teachers. Secondly, most educational services have focused on application of primary resources connected to current educational courses. Thirdly, cooperations among teachers, education experts, and archivists have been proceeded. Fourth, besides the direct instructions, printed materials and web based educational contents were also provided for students. Fifthly, utilization of primary resources were applied not only to history area, but also many subject areas such as social science, arts and humanities.

Schottky Emitter (SE)는 미국 FEI의 L. W. Swanson 그룹이 개발하여 상용화시킨 전자원이며, 고분해능 전자현미경용 전자원 시장에서 가장 큰 점유율을 차지하고 있다. 상온에서 작동하는 cold field emitter (CFE)에 비해 휘도(brightness)가 10~100배 정도 낮으나, 10-10 Torr 영역의 초고진공에서도 수시간 미만의 방출전류 안정성을 가진 CFE에 비해 수개월이상 안정된 방출전류를 전자현미경에 제공하므로, 반도체 측정, 검사 등과 같이 고분해능과 안정성이 동시에 요구되는 분야에서는 SE전자원은 필수 요소가 되어있다. 현재 SE 전자원은 일본, 미국, 영국의 4개사가 과점하고 있는 상태이다. SE 전자원이 안정되게 작동하기 위해서는 10~10 Torr 영역의 초고진공 환경이 요구된다. 한국 전자현미경 업체는 국책과제 등을 통해 SE 전자총을 개발해 왔으나, 진공기술과 광학계 설계기술이 부족하여 안정된 SE 전자총의 개발에 성공하지 못하였다. 본 발표에서는 10~10 Torr 영역에서 200 microA 이상의 전류를 안정되게 방출하는 SE 전자총의 전자빔 방출 및 진공특성을 보고한다. 시뮬레이션을 통해 구한 전차총의 전자원 위치 변화, 건렌즈 초점거리, 수차 등의 광학특성을 보여준다. 전자총을 전자현미경 경통에 탑재하고 제어하기 위해서는 전자총뿐만 아니라 전자현미경 전체의 광학특성을 이해할 필요가 있다. 전자총을 현미경에 통합 제어하기 위한 기술과제에 대해서도 간략히 보고한다.

최근에는 거의 모든 분야에서 ICT와 같은 기술기반 산업과의 융합을 통한 창업현상이 두드러지고 있어, 이들을 대상으로 한 연구는 개인 수준뿐만 아니라 팀 수준의 특성을 함께 살펴보는 것이 더 현실적인 상황을 반영하고 실무적인 시사점을 제공해 줄 것으로 판단된다. 팀창업일 경우 기업의 성과는 개인-팀 역량의 혼합 결과로 볼 수 있기 때문이다. 기존 선행연구에서는 창업기업의 성공과 실패를 가름하는 다양한 요인들을 제시해왔으나, 이러한 요인은 창업자의 개인적 특성, 보유하고 있는 자원 등에서 찾는 선행연구가 대부분이다. 관련 연구들을 종합하면 창업기업의 성장은 창업가 특성, 자원, 전략, 산업, 그리고 조직 구조 및 시스템의 함수로 정리된다. 그러나 창업팀에 대한 연구는 제한적이다. 이에 본 연구는 초기 창업기업의 성과에 영향을 미치는 핵심 요인으로 창업가의 특성인 창업역량(entrepreneurial competency)에 초점을 두고, 창업팀의 역량에 따라 어떠한 영향을 미치는 살펴본다. 개인의 특성에 집중해온 기존 연구에서 더 나아가 창업역량의 영향력을 창업가 개인 수준 및 팀 수준으로 구분하여 함께 살펴보고자 한다. 본 연구 결과를 통해 예비 창업가 및 초기 창업기업이 안정적인 사업화를 위해 팀구성을 어떻게 해야하는지 가이드라인을 제시할 수 있을 것으로 기대된다. 또한, 정부 지자체 민간 등에서 창업지원사업 운영 시 팀구성이 잘 된 창업기업을 선발하는 기준을 수립하기 위한 참고자료로 활용될 수 있을 것으로 기대된다.
