This study aimed to establish a conceptual scheme of the quality of university and to develop a set of structured indicators for assessing the quality of university based on the result of comparative analysis of major approaches in foreign countries. Reviewing extensive literatures regarding the quality of higher education, a conceptual scheme of the quality of university, in which three representative approaches such as a goal-accomplishment approach, a customer-satisfaction approach, and a value-added approach were emphasized, was proposed and the quality of university was defined as a function of harmonization of input-process-output elements of universities. To develop indicators for assessing the quality of university, four types of approaches including university accreditation system, commercially-producted university ranking system, college student survey, and direct assessment of students' learning outcomes were reviewed. Finally thirteen sets of evaluation indicators out of six countries were comparatively analyzed. The analyses focused on the format, the content, and the primary concept of the quality in each instrument and a draft of the assessment indicators were structured. The draft of the assessment indicators were verified through a panel of professionals. The final indicators assessing the quality of university consist of three dimensions and seven areas. The input dimension comprised institutional goals, human resources, and physical resources. In the process dimension, curriculum and learning process areas were included. And, finally, the output dimension consists of educational outputs and research outputs. Based on the outcomes of the study, the recommendations were suggested for improving and utilizing the assessment indicators of the quality of university.

The private security industry has expanded in proportion to economic developments throughout the world, largely because the existing security services provided by the government do not satisfy demands of various economic entities and people in the society for better security service. Therefore, it would not be unfair to say that security services by private sectors are decided by its quality, price, and customers' needs. A refined management system, however, is essential to assess qualification of security companies and their service quality, given the nature of public goods of security service. Despite the steady growth of private security industry in Korea, however, it has been continuously criticized that its security management system for better qualification of security guards, training, and private security companies have not been fully updated enough to guarantee good quality. This paper aims to gain insights to effective policy formation in the Korean private security industry, through reviewing the licensing system of private security guards and the Approved Contractor Scheme (hereinafter the ACS) in the UK- that has on one hand systematically regulated private security industry, but on other hand has enforced public-private cooperation by laying significant stress on autonomy of private security companies. The distinctive characteristic of the UK policy for the private security is that the Security Industry Authority (hereinafter the SIA), an independent authority, is leading development of the private security industry of the UK through specialized private security regulation and enhanced service quality. In addition, the UK is developing quality of security service with transparent financial management and recruitment of good quality security guards by adopting not only substantially specified regulations and standards, but the voluntary ACS system. Moreover, the SIA analyzes customers' demands for security service specializing the policy for private security through conducting a variety of surveys. With the analysis of the UK private security system, this paper suggests that the Korean government change from a non-specialized private security regulation system by the National Police Agency to an independently specialized private security authority like the SIA and adopt the compulsory licensing and the ACS system of the UK.

There are many weaknesses in sensor networks due to hardware limitation of sensor nodes besides the vulnerabilities of a wireless channel. In order to provide sensor networks with security, we should find out the approaches different from ones in existing wireless networks; the security mechanism in sensor network should be light-weighted and not degrade network performance. Sowe proposed a novel data origin authentication satisfying both of being light-weighted and maintaining network performance by using Unique Random Sequence Code. This scheme uses a challenge-response authentication consisting of a query code and a response code. In this paper, we show how to make a Unique Random Sequence Code and how to use it for data origin authentication.

세계화의 진전으로 사실상 국가간 장벽이 없어짐에 따라, 전문직 자격에 있어서도 각국이 공통으로 적용할 수 있는 국제적 기준이 필요하게 되었고, 이에 따라 UIA는 건축사자격에 대한 국제 기준이랄 수 있는 '건축실무에 있어서의 전문성에 관한 국제기준 권장안(UIA Accord on Recommended International Standards for Professionalism in Architectural Practice, 1999)'을 발표하였다. 때마침 WTO에 의한 전문서비스분야의 시장개방문화와 함께 우리나라의 건축사제도에도 일대 변혁이 불가피하게 된 것이다. 이에 우리 협회에서는 현안에 대한 신속한 대처를 위하여 UIA와의 관계정립이 필요하다는 판단하에 UIA 회원단체로서의 가입을 추진하는 한편, 구체적인 대안마련을 위한 연구를 진행하여 '건축사자격 상호인정에 따른 대응방안(1999.9)'을 발표하였고, '한중일 건축사협의회'를 설립, 3국의 공동대처방안을 모색하는 등 지속적인 노력을 기울여 왔다. 협회 뿐만 아니라 학회를 중심으로 한 건축학교과과정의 모델연구, 건교부와 건축3단체가 참여한 '건축사자격제도 개선방안에 대한 대응방안연구(2002.12)'등을 통하여 이미 5년이상의 건축학 교육과정이 신설되었고, 건축교육인증을 위한 인증원 설립준비가 진행되고 있다. 이러한 변화는 비단 세계화 혹은 무역자유화라는 현안에 대한 대응의 필요성 뿐 아니라 궁극적으로는 우리나라 건축교육의 질을 높이고 국제기준과 동등한 건축사제도를 갖춤으로써 건축사의 자질을 향상시켜 국제경쟁력을 강화하고자 하는데 목적이 있다 하겠다. 나라마다 건축사제도의 성립 과정과 배경이 다르지만, 대부분의 나라에서 건축사제도는 건축사단체에 의하여 운영되고 있다. 우리 협회도 최근에 진행되고 있는 인증원 설립을 위한 연구에 적극적으로 참여하여 주도적 역할을 담당하고 있기에, 관련 내용을 소개하여 회원여러분의 이해를 돕고자 한다.

Crystalline silicon photovoltaic module certification began in 2007. "Renewable Energy Equipment Certification Scheme" was implemented until July 28, 2015. Then, the scheme was changed to "KS Certification Scheme" since July 29, 2015. A total of 2,331 models have been certified by 2016. The proportion of multi crystalline modules in certified products is higher than that of mono crystalline modules, and Korean modules account for 78% of the total certification modules. Chinese solar cells account for the highest percentage of 40% of the total modules and 62.4% of modules certified in 2016 use Chinese solar cells. With the development of technology, module power is continuously increasing, and efficiency is also rising. The average efficiency of mono crystalline module is 0.74% higher than the average of multi crystalline module. As a result of comparing domestic module with Chinese module, the highest efficiency of mono crystalline module and multi crystalline module and the average efficiency of mono crystalline module are higher than those of Chinese module, but the average efficiency of multi crystalline module is similar to that of Chinese module.

The Accreditation Board for Engineering Education in Korea was founded in 1999 and the first engineering education programs were accredited in 2001. The purpose of accreditation was to attract outstanding students to engineering colleges as well as to raise highly qualified engineers who would be recognized internationally. The accreditation of engineering education has expanded as more and more colleges and programs are asking to participate in this accreditation program. This study examines the current position and future direction of Korean engineering education. To develop further, engineering education in Korea requires more support to attract outstanding students to engineering colleges and to provide high quality education. Also, Korea should become a member of Washington Accord to be recognized as international level of engineering education as well as active cooperation from engineering related organizations, institutions, and businesses.
