As the market for life friendly ICT (Information and Communication Technologies) services has grown up, high tech elevator with IoT (Internet of Things), a key area of the fourth industry, have become an indispensable part of life. Existing elevators are composed of up and down buttons to conveniently climb up and down high rise buildings, but there is a small inconvenience that everyone experiences depending on the characteristics of the user's composition, types of use, frequency, etc. Existing elevators are automatically closed if there are no people within the range of sensors, but they are inconvenient for the passengers with disabilities to carry luggage or to use. In this paper, the smart button, a hardware firmware device, was designed to relieve user inconvenience by opening the elevator for a certain period of time considering the boarding time of the passengers.

We, in this study, tried to examine the influence of business environment, organization structure and information technology characteristics used on the performance of the information systems in Information and Communications Industries. The result shows that frequency of system usage and users' satisfaction are positively affected by the factors of business environment, organizational structure and information-technology. The user satisfaction of the system is affected by the frequency of system usage. Both financial performance and non-financial performance are affected by the frequency of the systems usage and user satisfaction of the system. With path analysis, we verified the overall model goodness-of-fit verified for the research model. The result shows that organization structureand technological factors are positively related to the frequency of usage and user satisfaction of the system, while the environmental factors are not. The frequency of system usage is not linked to both financial and non-financial performance. The user satisfaction of the system does not affected to the financial performance. In conclusion, the usage frequency and user satisfaction of the system are the moderating variables affecting business performances. These two variables are affected by the environment, organization structure and information technology. The Path analysis also supports the relationships among these variables.

Images have been substantially searched and used due to not only the advanced internet and digital technologies but the characteristics of a younger generation. The purpose of this study aims to discuss the ways on expanding the access points to images by analyzing the needs of users in context of everyday life. In order to achieve the purpose of this study, 105 questions of image seeking in NAVER, which is one of social Q&A services in Korea, were analyzed. For the analysis, a two-dimensional framework with image uses and image attributes were utilized. The findings of this study demonstrate that considerable use purposes on data oriented pole, such as information processing, information dissemination and learning are identified. On the other hand, image attributes from the needs of image show that non-visual aspects including contextual attributes are recognized substantially in addition to the traditional semantic attributes.

인터넷은 한국사회 전반에 많은 변화를 초래하였다. 인터넷이 빠르게 확산되어 2004년 말에 인터넷 이용자 3,000만 명 시대를 열었고 이동전화, 초고속 인터넷 등 새로운 정보기술이 보편적으로 활용되는 단계에 이르렀다. 그에 따라 개인 홈페이지가 커뮤니케이션의 새로운 수단으로 자리 잡았고, 이에 따른 새로운 네티즌 문화를 탄생시켰다. 사회문화적 측면에서 그동안 정보화가 창출한 가장 큰 변화는 조직사회의 변화, 교육환경의 변화, 문화생활의 변화를 들 수 있다. 인터넷이 조직사회에 미친 영향은 전통적인 연공서열식 피라미드형 조직구조가 새로운 네트워크형 조직으로 발전하였으며, 노동시장도 장소에 구애받지 않고 이동원격근무(mobile Office)로 발전하는 추세이다. 그리고 교육환경은 가상공간을 통한 다양한 교육정보 접근기회를 확대하고 있으며, 사람들의 사고방식, 생활양식, 가치관의 변화도 수반하고 있다. 반면에 인터넷 사회는 한국사회 전반의 변화와 함께 정보화의 역기능 현상도 다양하고 광범위하게 확산되고 있다. 인터넷이라는 온라인상에서 다양한 주제로 서로 만나고 정보를 교환하는 사이버 공동체(Cyber Community)는 온라인 공간에 한정되는 것이 아니라 현실공간으로 확장되어 나타나고 있으며, 인터넷 중독문제는 개인뿐만 아니라 가정과 사회에도 부정적 영향을 끼치고 있을 뿐만 아니라 안티사이트도 진정한 대안문화로 자리 잡지 못하고 인터넷의 익명성을 이용해 무차별적인 비방과 욕설이 난무한 과도기적 현상을 보이고 있다. 이제 인터넷은 한국사회의 모든 것과 깊은 관련을 맺는 매우 중요한 일부분이 된 것이다. 인터넷은 20세기 공학기술이 성취한 위대한 업적 중의 하나이다. 인터넷은 단순히 정보화 사회를 실현하는 것이 아니라 인간의 삶의 가치, 생활의 편익 등을 증대한다는 믿음 때문이다. 한편 현실은 여러 가지 역기능이 함께 나타나고 있다. '네티즌 윤리강령'까지 선포했지만, 진정한 네티즌 윤리는 강령을 선포했다고 저절로 확립되는 것이 아니다. 네티즌 각자의 실천의지가 있어야 한다. 인류가 새로운 이상향이라고 추구하는 가상사회는 윤리적인 사고와 행동으로 질서를 유지하지 못하면 인류의 밝은 미래는 보장할 길이 없다. 21세기 정보화 사회, 인터넷 사회를 맞이한 우리는 이 세상을 참으로 살기 좋은 세상으로 만들어야 할 고귀한 책무를 안고 있다. 아무리 험한 길, 어려운 과제라 할지라도 그 목표를 잃어서는 안 되며, 그 해답을 얻는 노력을 결코 게을리 해서는 안 된다.

It is anticipated that the introduction of ICT to street-level welfare administration will smoothen communication processes between frontline officials and recipients by intensifying welfare information sharing and distribution. However, through a case study of ICT-mediated street-level welfare administration in South Korea, this article claims that ICT can deteriorate frontline official-recipient relationship into more distrustful and disempowered directions. This study demonstrates that ICT tends to replace face-to-face rapport building between officials and recipients with mechanical checking and complaining processes. ICT-based welfare administration can also disempower the autonomous interactions of street-level actors by surveiling every working step of frontline officials and the daily lives of recipients. Through an investigation into street-level bureaucracy in an information society, this study criticizes the dehumanization tendency of ICT-mediated human services and raises a question in the roseate vision on social welfare informatization.

For urban parks' rational and efficient management, research on creating green spaces in living area through citizen participation is continuously being conducted. However, in existing studies, citizens are recognized as a homogeneous group, and research on the intention to participate in park management according to user characteristics has not been conducted. A few studies have attempted to show differences through conceptual variables, such as user satisfaction and attachment to parks, but studies on sociodemographic factors, such as the users' age, have not been conducted. This study was conducted to ascertain the differences in preferred parks and park management participation methods by age, targeting various parks located in ten districts of Incheon Metropolitan City. Regression analysis was performed after collecting 1,226 questionnaires, applying a population-proportional allocation in the ten districts. As a result of the study, it was found that the difference according to the age of users has the most influence on the willingness to manage the park rather than the satisfaction or other factors. Also, a chi-square analysis was conducted to find the differences in preferred urban parks and management methods by age. The results showed that the choice to manage parks was statistically higher for those in their 50s or older, and the differences in preferred park types and desired park greening methods suggested implications for park management plans by age.
