열전달에는 많은 개념과 방법론이 포함되므로 그 범위에 있어서, 적어도 다른 어떤 열과학보다도 광범위하다. 이 제목의 첫 과목을 가르치는데 있어, 교수는 토픽의 내용, 수학의 정도, 컴퓨터 사용 및 실험 등에 있어 많은 선택에 직면하게 된다. 이 선택은 학생개발목표는 물론 기자재 및 시간제한 등에 기반을 두어 이루어져야 한다. 열전달 첫 과목의 주된 목적은 학생이 열시스템 설계와 성능에 관계되는 문제를 합리적으로 취급할 수 있도록 준비시키는 것이어야 한다. 따 라서 전달, 대류 및 복사의 기본원리와 열시스템 해석의 방법론에 중점을 두어야 한다.

The upcoming 'creativity society' beyond the knowledge information era requires 'knowledge producers' being capable of expressing their own ideas creatively, rather than 'knowledge consumers'. These days, in the computing environment, physical computing tools which support learners' productive activities beyond their simple function of operating computers are emerging. Among them, Raspberry Pi is exemplary. The computing PC worthy $35 is economic and supports implementation of interactive physical system through the H/W and programming control to detect and respond to the analog world. As a fundamental study of educational application of Raspberry Pi at elementary school and Raspberry Pi, this work was to look into characteristics, advantages and disadvantages, and application examples of the computing tool. Also this researcher conducted a survey with teachers in field to investigate the suitability of Raspberry Pi as a tool in the category of 'understanding of information devices and to explore their awareness of Raspberry Pi. As a result, it was analyzed that Raspberry Pi was a learning tool to support about 74% of educational contents and that teachers showed positive replies in all categories of the survey of their awareness.

본 연구는 사용자 특성 중 조직에서 통제 가능한 요인의 사용자의 태도 및 교육· 훈련이 정보시스템이 실행 성과에 미치는 영향을 검증하기 위한 것이다. 이를 위해 본 연구 에서는 최근 신정보시스템으로 전환한 D사의 사용자를 대상으로 설문조사를 실시하여 다음 과 같은 결과를 얻었다. 첫째, 사용자 태도와 교육·훈련은 각각 독립적으로 정보시스템의 실행 성과에 영향을 미치는 것으로 나타났다. 둘째, 사용자 태도와 교육·훈련이 결합한 상 호작용 효과는 시스템 사용도에는 유의적인 효과를 미쳤지만, 사용자 만족도에는 유의적인 효과를 미쳤지만, 사용자 만족도에는 유의적인 효과를 미치지 못한 것으로 나타났다. 이러 한 연구 결과에 비추어 볼 때, 조직에서 정보시스템의 실행 성과를 높이기 위해서는 사용자 태도를 호의적으로 변화시키고, 사용자에 대한 교육·훈련을 많이 시켜야 하며, 특히 사용자 에 대한 교육·훈련은 차별화하여 실시하여야 한다는 것이다.

This study was conducted to derive a model of the legal system that is the basis for realizing the service economy, political administration, and social education system. Based on the experience of mankind's legal system operation in the historical era for the past 5,000 years, a legal system model that will make the future human society sustainable has been established. The problems of the current legal system were analyzed at the fundamental level. The root cause of injustice and unfairness was analyzed and a new legal system was designed. Through the legal systems of various national societies that have been attempted in the history of mankind, the structure of the legal system that is desirable for the modern society was designed. Human society, which has experienced how much good legal system has been and is being abused by human irrationality and nonsense, needs to make an effort to change the legal system paradigm itself by learning lessons from failure. This study derives the basis for a legal system that can realize justice and a fair society in the long term. It proposed a model for improving the legal system that allows human society to be happy for a long time. To this end, the fundamental role of the legal system was analyzed at the ideological level and the problems of the current legal system were presented. In addition, the problem of fundamental assumptions about human nature was analyzed and improved assumptions were presented. The structural system of the current legal system was analyzed and a new structure was proposed. In addition, a plan for the operation of a new legal system based on a new structure was suggested. The new legal system was named servicism system. This is because it is a model centered on thorough checks and balances between all opponents, not a simple linear one-dimensional legal system, but a multidimensional legal system, and because it is a viewpoint that clearly recognizes both human reason and desire. The new system is a model that reflects the confrontation between the rule of law and the non-law rule and the confrontation between the power people and the general public. A follow-up study is needed on a concrete plan for transitioning from the current legal system to a new legal system.

This paper is conducted for automatically recommending and providing information services desired by users on websites of local governments and public institutions with vast amounts of information, In this system, we defined a method of collecting data based on the SiiRU CMS system that collects and preprocesses data, and a study that provides curation services (contents and menus) to users through a collaborative filtering algorithm based on machine learning. Also, the data used in the paper is conducted based on about 1 million data collected in 2019. The analyzed data can provide important information that cannot be easily accessed by providing a cloud tag service or recommended menu for users to conveniently view, and the environment configuration that can realize this service to local governments and public institutions is also provided.

Along with developments of information and communication technologies, internet has spread not only all over the society, but also our everyday life deeply. Recently, requirements for e-learning using internet in the educational aspect have a great influence on the changes of school educations. Cyber Home Learning System, in particular, has been implemented throughout the nation for the purpose of reducing private expenditure for education and promoting substantial improvements in quality of public education. However, there have been exposed many problems with respect to quality of operations and managements of the system comparing to its quantitative growth, and so, at this point in time, researcher conducted analysis of actuality of perceptions of both elementary and middle school teachers with a focus on the case of S System in K province. To test this, total 278 participants were sampled from the elementary schools (139 teachers) and the middle schools (139 teachers) located in K province and were asked to complete a survey and the results therefrom were analyzed accordingly. Results from the analyses revealed that elementary school teachers responded more positively than other respondents in the most areas, including supply of a variety of learning contents of S System, quality of contents, and providing for helps insomuch as to complement school works, etcetera. In addition, researcher has found out that, to make the system become all the more efficient, it shall be required to establish a strategy in order to induce students' interest in the system, as well as to construct infrastructure for facilitating the use of computer. And that there are also needs for continuous supports from both the school and the education authority concerned, and for method of flexible operation of curriculum.

In this paper, we present a simple ground receiving station as an educational method for a satellite system. Our system is produced similarly to the existing fixed ground station in terms of function by using satellite communication technology and related software commonly used in the amateur radio field. In addition, we conducted operation test to receive signals from operating satellites and confirmed the possibility of using them as a way to educate satellite systems, such as understanding ground station systems through satellite reception experience and satellite state information acquisition, and further designing satellite systems.
