Millimeter wave is expected as the unlimited useful frequency resources for the next generation wireless communication services. In the past, its usage was limited to the military warfare due to lack of millimeter devices. The development of GaAs pHEMT in 1980 and the progress in the processing technologies made the new consumer wireless services possible utilizing millimeter waves. Specially, most of passive components necessary for circuit design can be integrated with GaAs pHEMTs and this removes the difficulty in assembly unavoidable in hybrid design. InP based pHEMTs developed later possess all the properties of GaAs and it shows many advantages in higher frequency applications. In this paper, the status and trends of those devices and MMICs are presented and the future developing trends is also described.

Modular construction is recognized as a construction method with various advantages, such as shortening the construction duration, achieving quality control through factory production, ease of maintenance, and reduced construction costs due to reduced weight of materials. However, despite efforts by the modular industry and government to activate modular construction, it has rarely been established in the domestic market. Currently, there are technical limitations to the modular construction fire resisting technology applied to general buildings. The lack of access to modular construction fire resistance regulation is considered a major factor. In this study, the current status and problems with modular construction fire resistance regulation, a significant hindrance factor, were considered to activate modular construction. This study is intended to present a direction for institutional improvement in modular construction fire resistance and a direction for research and development.

Information Technology (IT) makes a great contribution towards improvement of productivity in construction industry. Because most of researches of construction industry's IT are focused on the whole field of the industry or development of information system, however, these have no regard for conditions in fields. Thus, this study proposes the requirements in order to improve the productivity and efficiency of field execution of construction industry. To achieve this aim, the surveys are conducted of the problems and conditions of IT application on site workers and managers. As a result, the followings are suggested: (1) user training should be exercised continuously, (2) infrastructure of IT constructed, (3) total management system of field execution developed, and (4) the development of IT system focused on fields. Therefore, this study provides meaningful proposal that can be set up basic direction toward IT investment and IT system development.

Although Korea's e-government is at the level of developed countries, it has been pointed out that the introduction of SOA is too slow. It also points out that the government's low SOA level has a negative impact on the UN's e-government rankings. In 2002, Korea introduced the first web service in the domestic public sector. At that time, there were few cases in the world where Web services were introduced in the public sector. However, the advanced e-government advanced countries already have SOA ideology based on e-government. Denmark and so on have SOA ideologies on the basis of e-government, and many countries make and use service repositories. In this environment, we analyze the application status of web service centered on the case of e - government in Japan.

As ubiquitous technology has been developed and has come into everyday life, it has been integrated to tourism information service. However, each regional government develops ubiquitous tourism information service independently without successful example or standard. Therefore, this paper aims to analyze existing cases of domestic ubiquitous tourism information service as a foundation research to establish standard and effective development strategy for accelerating ubiquitous tourism information service in the future. First, ubiquitous technology trend which can be adapted to tourism information service was reviewed by secondary research. Second, representative cases of ubiquitous tourism information service were collected and analyzed in four aspects such as adapted ubiquitous technology, adapted device, service content and type of content. Finally, overall development strategy of ubiquitous tourism information service was discussed based on the analysis result. This paper contributes to get an outline of present conditions and problems of existing ubiquitous tourism information service, suggest overall development direction for ubiquitous tourism information service and point out necessity of the standard and unified plan for nationwide development and management.

This study is conducted to improve the quality of healthcare services responding to COVID-19 by applying the public service quality management framework that is developed from ISO18091:2019 by the Ministry of the Interior and Safety of South Korea. The COVID-19 pandemic has been impacting the world since early 2020, and now in November 2020, it still has not been eliminated. The Korean medical institutions were able to prevent the spread of COVID-19 by agile test and strict cohort isolation. As a result, the so-called K-medical defense has achieved a positive reputation from around the world. In this study, we check and evaluate the current status of the COVID-19 response targeting some Korean hospitals by applying a quality control checklist based on the public service quality management framework. Status of 7 categories are analyzed based on the interview with 3 medical institutions. We also suggest improvements for better medical service quality in case of COVID-19 being prolonged.

Purpose: As the Act on Punishment of Serious Accidents came into effect in January 2022, it is becoming a big social issue in the labor and management circles. The purpose of this law is to analyze problems and suggest improvement plans so that the purpose of protecting lives and bodies by preventing major accidents can be met. Method: The main contents of the relevant law were identified, and the current application status of the currently enforced law and problems by law were analyzed. Result: Currently, more than 50 accidents have occurred and they have been classified as serious accidents, and no punishment has been imposed under the relevant laws. There are four major problems: 1) the issue of equity in the applied workplace, 2) the lack of clarity in some legal provisions, 3) the issue of entrusting the obligation to secure safety and health to private organizations, and 4) the issue of excessive punishment regulations. was analyzed as. Conclusion: As the law is in the early stages of enforcement, there are trials and errors, but revisions are necessary through the efforts of the labor and management circles to meet the establishment and purpose of the law.

Information technology is a useful strategic weapon that can create competitive advantage and new business opportunity by applying it in the organization' value chain. IT convergence can be understood as an attempt of industrial level IT adoption to facilitate the innovation of the industry and the birth of a new industry. This study provides the comprehensive review of the Korean government' three IT assimilation programs, ubiquitous technology diffusion program of the Ministry of Knowledge Economy, u-service program of the Ministry of Public Administration and Security, and u-Defence cooperation program of the Department of Defense. The analysis is done through the interpretation of the existing literature and the logic model. The result proposes inter-agency cooperation and building of new technology road-map in the planning stage, flexible management in the execution phase, and failure tolerant evaluation system. The proposal for developing competencies and institutional foundations for IT convergence also presented.

안전한 정보시스템 사용 환경 구축을 위하여 미국이 TCSEC을 개발한 이래 국가별로 자체 정보보호시스템 평가기준을 제정하여 사용하였다. 유럽에서는 영국, 독일, 프랑스가 중심이 되어 ITSEC을 개발하였으며, 이후 미국, 캐나다 및 유럽 4개국이 공동으로 모든 IT 보안성 평가에 적용할 수 있도록 CC를 개발하였다. 대부분의 국가는 초기에 정부 기관에 의해 평가가 이루어졌으나 평가수요 확대 및 시장성장 등에 따라 민간 평가기관을 지정하여 운영하고 있다. 본 고에서는 국외 민간평가기관에 의한 평가 현황을 분석하여 평가 동향 및 향후 전망을 살펴본다.
