Twitter, Facebook, and KakaoStory are the major SNS in Korea. Social knowledge production is being produced by those services from numerous collaboration and co-participation in those SNS. Wikipedia or Naver JishikIN service was regarded as the representative product of collective knowledge production during the wired internet era. However now at the wireless internet era centered with smart phones, various forms of collective knowledge production would be achieved by connecting to SNS in real-time. In this thesis, the survey data of collective knowledge production for users of three SNS have been compared and analyzed. The difference of the collective knowledge production mechanism among Twitter, Facebook and KakaoStory has been studied and compared through three variables: the motivation of collective knowledge production, the preference of collective knowledge production model, and collective knowledge production cultural perception. As a result of the analysis of the discriminant factors for three SNS user groups, it turns out that the diversity-toward usage motivation, personal contribution motivation, and collective knowledge production tendency perception are the most influential variables. This thesis is of significance in that it unites the value of social science such as social capital and collective knowledge production from the viewpoint of computer science and opens the new chapter of collective knowledge production with the real-time SNS of wireless internet from the wired internet.

With a rapid growing of information networks and development achievements in mobile technology the spatial information is one of the most important resources for modern daily life. But the speed of spatial information technology trends are far from the real service demands as compared to the other relevant fields, and it would be natural that this unbalanced gap between the supply and demand of spatial information technology is being resulted from the absence of appropriate modeling concepts at some extents. In this paper there would be shown a new approaching model for the spatial information system based on agent concepts, which is able to perform some spatial tasks if properly implemented afterward. And to give resonable background of the new modeling framework here also some known critics for the commonly used modeling approaches when they applied to spatial information modeling followed by several alternative requirements for a good spatial modeling framework. And also there would be some considerations for applying this approach to the marine geographic information communities.

The purpose of this study is to develop a measurement tool for the quality of information commons. Information commons is a physical, technological, social, and intellectual place where library users can experience various educational, research, and cultural activities. It is recently gaining popularity and several libraries have implemented it to help users share knowledge and interact with each other. It also intends to provide a place for collaboration, learning, and rest. Despite its benefits and usefulness, there is no measurement tool explicitly designed for the quality of information commons. This study used in-depth personal interview, compared prior studies, and conducted a pilot study to elicit library users' perceptions on information commons and factors influencing on the perceived quality of information commons. Groups of initial items were emerged through classifying and clustering key concepts in the data. Then, the validity of the items were verified through a pilot study. The findings of this study will be useful for developing more reliable and valid survey measurement tool.

It is an undeniable fact that the modern people's interest in knowledge and information and their roles are some of the core factors used to define the modern society. Besides, as phenomena indicating and leading the modern society, we have fusion, hybrid and convergence, etc. that combine several different elements into a new one. Such changes in social, cultural and technological circumstances require a paradigm shift for the composition of knowledge and information facilities and space. However, more diversified and advanced recently, interfaces for the delivery of knowledge and information cause users to show new behaviors and even change the spatial concept with space composition elements hybridized. Especially for the space of libraries, it is necessary to access and utilize any forms of knowledge and information data (digital + analog) regardless of time and space limitations and approach with an integrated spatial concept likely to change flexibly depending on social demands. In this light, this study aims to make a basic proposal for sustainable integrated-type hybrid space for the space of a public library in this era of knowledge and information. Particularly, this study intends to seek a way to establish a hybrid space model that can effectively converge the most important factors of the space of libraries (human-space(network)-information). With 18 different cases, this study analyzed knowledge and information composition systems, knowledge and information delivery systems and users' space systems. As a result, this study extracted 3 kinds of models, an information-based model, a culture-based model and an education-based model, with the integrated hybrid space model of knowledge and information facilities

In this study, deals with selection of monitoring objects to handle emergency cases of multi-modal transfer stations and information required for emergency surveillance, recognition, verification, propagation, processing and situation closing. Furthermore, this article suggests integrated management scheme for the above information and methods which offer appropriate information required for situation handling decisions at each stage of situation changes. The transfer station which consists of facilities, passengers, and transportations has limitations in required monitoring information. So, for the situation recognition and handling strategy, case-based reasoning of the expert system was used to apply experience, knowledge, and past cases of situation handling experts. The article also suggests methods to control facilities which are operated at transfer stations and these methods can minimize spatial confusions and damages at the emergency situation. The real time situation information will be shared by proper facility controls to support services from external institutions.

Q-Learning, a representative algorithm of reinforcement learning, experiences repeatedly until estimation values about all state-action pairs of state space converge and achieve optimal policies. When the state space is high dimensional or continuous, complex reinforcement learning tasks involve very large state space and suffer from storing all individual state values in a single table. We introduce Q-Map that is new function approximation method to get classified policies. As an agent learns on-line, Q-Map groups states of similar situations and adapts to new experiences repeatedly. State-action pairs necessary for fine control are treated in the form of rule. As a result of experiment in maze environment and mountain car problem, we can achieve classified knowledge and extract easily rules from Q-Map

강수량은 수문 순환의 결정적인 연결 고리이며 공간적, 시간적 변화는 매우 크며, 또한 전 세계적인 범위의 강수량 자료는 지구상의 수문 순환에 대한 이해와 날씨 및 기후 예측을 위해 필요하다. 그리고 지역적 강수량에 대한 지식은 사회 복지에 필수적이다. 지상에 있는 강우관소에서 관측된 강우는 본질적으로 강우의 공간적 불균일성을 반영하기 어려우며, 관측 주기가 하루 이상으로 긴 경우에는 홍수와 연계한 생태-수문학 연구에 적용하는데 한계가 있다. 또한, 지상계측 방법은 해양, 극지방 및 산악지역의 강수량을 관찰하는데 어려움이 있다. 이에 반하여 원격탐사 기술은 지구 강수를 관찰하는데 많은 도움을 주는 기술로 인식되고 있다. 위성자료를 이용한 강우 추정은 지상 강우관측소 및 기상레이더와 비교하여 광역적 공간범위를 대상으로 하며, 지속적이고 균일한 강우를 생산한다는 장점을 갖고 있다(Hong et al. 2016). 위성강우 자료는 일반적으로 전 세계 강수량에 대한 지식과 글로벌 수문순환에 대한 연구를 촉진하고 있으며, 특히, 동아시아, 동남아시아, 아프리카 등지에는 수문학적 미계측 지역이 많기 때문에 위성강우 자료를 이용한 강수량 평가에 대한 연구가 다수 진행되고 있다(Hoscilo et al., 2015; Dembélé et al., 2016; Dandridge et al., 2019; Kim et al., 2019; Yuan et al., 2019). 본 연구는 위성으로부터 유도된 강수자료 중 NASA의 IMERG, NOAA의 CMORPH, 그리고 일본 JAXA의 GSMaP의 위성강우자료와 국내의 ASOS 시간강우자료의 비교를 통해 위성강우의 정확도를 평가하는 것을 목적으로 하고 있다. 분석 결과 총강우에 대한 편이는 그림 1에서 보는바와 같이 CMORPH가 가장 작고 가장 최근에 제공되기 시작한 IMERG 강수자료가 가장 큰 것으로 분석되었다. 지상계측강우와의 상관계수는 1시간 및 3시간의 시간해상도에서 2019년 18호 태풍 미탁(Mitak)의 경우 IMERG 및 GSMaP 각각 0.63 및 0.60와 0.73 및 0.70으로 분석되었다.

Marshall Mcluhan, a media scholar, created the word Gutenberg Gaaxy meaning the new environment formulated by printing technic and he insisted that it changed human life entirely. In the history of human, the media evolved into printing technic through oral and transcription. This evolution of media and the environment created by the media are the most important point of Mcluhan's theory. He sees the world as the result of media evolution. In mcluhan's sight, Gutenberg Galaxy is the first environment composed by the media. Based on the mcluhan's theory, this study focused on the environment created by the media and applied it into the western music history. The link of the Gutenberg Galaxy and the western music, especially in romantic era, will be the main subject of the study. The Book is the most representative media of the printing technic. In the era of oral and transcription, the communication was limited by the spatial restriction. However, the book was free to spatial condition and this character of the book made the knowledge free. The knowledges delivered by the oral and transcription were mostly the matter of mundane world because they are so close to the human life, even though they are narrating about the God's world. The book, free to expanding the knowledge beyond the world, made the knowledge transcendent and expanded the sight of the humans into the transcendent world. The modern western world is the product of the expanded knowledge by the book and so does the music. In the time of printing technic, the music begun to gain the population by the printed sheet music. As delivering the music through the printed sheet, the music received transcendence and mystery as meeting the spirit of the times. This link formed by the time of Gutenberg Galaxy will be the main focus of the study and it will prove the link between the media and the western music.
