1950년대 동란을 거쳐 1960년대 초반부터 시작된 경제개발계획에 의해 급격한 경제성장으로 인해 산업 인구의 대도시 집중화에 의하여 전기의 공급력 부족 현상은 지속되었다. 따라서, 이때부터 성장한 경제배전계통은 수적으로도 많고 광범위하게 산재되어 있어 인력에 의해서는 더 이상 효과적인 관리가 어렵게 되었고, 사회가 고도 정보화로 진전되면서 수용가는 한층 더 높은 공급 신뢰도와 고품질의 전력공급을 요구하고 있다. 이러한 변화에 따라 전력공급자는 전력계통에 대한 감시와 제어를 통하여 항시 안정적이고 신뢰성있는 운용을 하여야한다. 이에 따라 배전계통에 설치된 배전설비를 컴퓨터와 통신수단을 이용하여 원격지에서 감시 제어할 수 있는 배전자동화 시스템에 대한 연구가 오래 전부터 이루어져 왔으며 효과적으로 양질의 전력을 공급하고자 배전자동화 시스템(DAS)이 도입되었다. 본 연구에서는 능동적인 감시 및 제어기능을 제공하는 객체지향형 능동데이터베이스 알고리즘을 사용하여 배전계통 제어에 적용하였고 기존의 인터넷 통신망을 통한 감시 및 제어가 가능하게 하였으며 이러한 효과에 의해 배전계통이 여러개의 다른 전력회사로 분할될 경우 각기 존재하는 다른 시스템에 대하여 인터넷을 통한 연계가 가능하도록 하여 통합적인 데이터베이스를 구축하는데 용이하게 하였다.

Blockchain, which is the basis of virtual assets such as cryptocurrency, is receiving great attention as one of the cornerstone technologies of the 4th industrial revolution. Blockchain is a technology that can fundamentally change our lives not only in finance, but also in politics, logistics, and culture. However, it shows lower-than-expected usability because it is complicated to learn and is continuously being developed. In this study, we tried to investigate whether the Technology Acceptance Model(TAM) of virtual assets can be changed through education on the underlying technology, blockchain. A video-based online experiment was conducted with a total of 103 participants and examined how the type of training(positive, negative) and measurement timing(before, after) affect perceived usefulness, perceived ease of use, acceptance, which are TAM variables, and trust and security, which are related to blockchain characteristics. As a result of the experiment, interactions were found in all dependent variables according to the type of education and measurement timing. Specifically, groups that received negative education had no difference in all variables before and after, but it was found that groups that received positive education showed an increase afterwards. Through this, it can be seen that the effect of education based on the anchoring effect is also shown in the intention to use virtual assets using block chain technology, suggesting that the intention to use blockchain related technology can be increased through positive education.

The inspections that are being done on current bridges in our country are made to go through a process of being recorded on the management system and then converted by the computer. This has deteriorated the credibility of manual-analog types of data, inefficient care of information, and produced potential problems of the structures of bridges through subjective evaluations. In order to solve these troubles, this research has aimed at effectiveness, management, and convenience so that the inspector at the actual scene of the bridge structures will be able to achieve the primary purpose of infrastructure safety through precise supervision. To assist this, this study has suggested a state of the art IT intellectual management system that has applied RFID. This system has been designed to decrease the inspecting time on the actual scene, which will provide more time for efficient inspection and by using the converted DB, managing and utilizing high quality data will come naturally and through the objective evaluation, it will be possible to make exact judgments of the structures of the bridge. Also, regardless of the location, it has been found that the work performance was excellent through highly effective management.

Conventional studies on technology acceptance have focused on information technology for utilitarian value and hence based on 'theory of reasoned action'. Correspondingly, the studies depend on perceived usefulness and perceived ease of use as rational decision making elements. However, in ubiquitous society, innovative technologies are applied to non-task area, as well as task-oriented area. Therefore, users are more influenced by affective factors than cognitive factors in causing their usage intention. In line with those discussions, we cannot make sure that the conventional technology acceptance model could fully explain the current u-service acceptance phenomenon. Hence, to overcome the limitations of the prior technology acceptance studies, we propose an amended TAM which includes one hedonic factor and two factors on ubiquitous computing technology : ubiquity and intelligence.

This study is focused on the historical route in which reconciliation between work and family has been operating in the United States whose welfare standards are low, by using analytic narratives, from late 19th century to early 20th century. The first step saw an increase in the social advancement of unmarried women due to the increase in employment in the occupation of white-collar, as well as the increase of women in the Academy and in educational institutions. In the second step, the social advancement of married women was increased by the enforcement of the New Deal, consumption capitalism, and World War II. In the third step, the sphere of highly-educated women was expanded to a professional one through active measures aimed at gender equality, and the women's liberation movement of the 1960s took place. The United States' path model was completed in the fourth step. This study show that the most important factors have a significant influence to complete route of the American's Route were individual efforts of women (capacity building through the academic and the powerful women's movement) and the individual employment relationship in labor market. This study shows that individual efforts of women, especially in building capacity through the academic and the powerful women's movement, and the labor market, whose individual employment relationship is well-developed, have a significant influence on completing the route of the highly educated middle-class women in America.

In modern society, people will obtain the necessary goods and find meaning of himself and his community through jobs. The meaning of job for people with disabilities is identical with people's with non-disabilities and people with disabilities will live as a member of society through jobs. Because people with hearing impairment have a problem about job such as the short longevity and high turnover, vocational aptitude test which evaluates psychological characteristics, aptitudes and interests is necessary for them. In this paper, we design and evaluate the picture vocational interest inventory supporting the Internet as a vocational aptitude test for people with hearing impairment. We use the picture vocational interest inventory of Korean Employment Development Institute as a implementation target. The previous tests for people with hearing impairment have a problem which an examinee, an examiner and a sign language interpreter are involved in the test at the same space and time. Therefore, our picture vocational interest inventory has no limitation of time and space because it processes on the Internet.

This study is to find the key factors of the Internet of Things for development in public sector. In previous studies, it is said that Internet of Things can work digital system without human operation and gives a lot of outputs(information) users. Generally, people are a subject of operating digital system in traditional way, while people are an object on the internet of things. In other words, it is possible to work digital system with only networking from things to things. After all, it is reported that these advantages of the Internet of Things make possible to reduce social costs significantly in public sector. However, despite the strengths of the Internet of Things, there is a specific user acceptance of the technology factor for the Internet of Things rarely. It means that developing of the Internet of Things only focuses on the final purpose. If the focus on development meet this purpose, the user is ignored for the specific reason that using a technique. As a result of this, many users gradually decrease the continuous using of the Internet of Things. Thus, in this study, we need to find what critical factors should reflect to the Internet of Things in public sector. To find this result, there is no choice to use Technology Acceptance Model(TAM). Many researchers have proved that Technology Acceptance Model is valid through the four process in model introduction, confirmation, expansion and refinement from 1986 to 2003. The results of this study showed that the result explanatory power of Internet of Things in public sector is the most important factor affecting only perceived social usefulness and ease of use. Finally, it can be seen that the user has a positive attitude toward use, which has a positive effect on the intention to use continuously. The implications of this study are summarized as follows: When the public Internet of Things service is provided, it means that the user can easily understand the result, and when the person and the object communicate the result to each other, they should be able to communicate with each other. This means that a lot of user effort is needed to understand the outcome of the public Internet of Things being provided.
