This study is aimed to interpret the raw material characteristics and manufacturing technology through physical, mineral and geochemical analysis of the brown-glazed stonewares and roof tiles excavated from the Hong Nang Sida temple in Laos, which was built in the 12th century. The glaze of brown-glazed stoneware is a typical lime serial with CaO content of more than 15 % and they were vitrified. The body is the combination of quartz, mullite and cristobalite, but had not vitrified texture, and therefore, which is assumed to have been fired more than 950 ℃. Meanwhile, The roof tiles are unglazed and its outer color is reddish brown, whitish grey and bluish grey. The bluish gray tiles has sandwich structure, which seem to experience imperfect reducing environment. The tile samples with a number of amorphous iron oxide nodule had a very similar chemical composition. In conclusion, it is assumed that the clay source was made from raw material produced from the same bedrock. The firing temperature of roof tiles were divided into less than 900 ℃, 900~950 ℃ and greater than 950 ℃ according to detection of micas, hercynite and mullite.

The purpose of this study was to propose curriculum and teaching sequence for seasonal change by exploring a learning progression. For the purpose, 4 steps of construct modeling approach (specifying construct, item design, outcome space, and measurement model) proposed by Wilson (2005) was applied. In the stage of specifying construct, 'length of shadow according to seasons', 'position of constellation according to seasons', 'seasons of the southern hemisphere and northern hemisphere', 'cause and phenomenon of seasonal change' were selected as the subconstructs of seasonal changes, and constructed a construct map showing the level of development from level 1 to level 4 for each subconstruct based on the results of the previous research. In the item design stage, we developed five assessment items consisting of 3 items in the form of C-E (choose and explain) and two items in the form of CR (constructed response), applied it to 383 elementary, middle and high school students. In the outcome space stage, the students' responses to the assessment items were categorized based on the construct map. The categories were classified into 4 levels according to student ability and scores of 1-4 were given. In the measurement model stage, we applied the partial credit model of the Rasch model and compared whether the learning pathway created from the results of students' response coincides with the construct map. Based on the results of the research, we modified the construct map and finally created hypothetical learning progression on seasonal change. Finally, we proposed an orientation of curriculum amendment and effective teaching sequence for seasonal change.

This study examined the current practices of Research Data Management (RDM) services recently built and implemented at research university libraries in the U.S. by analyzing the components of the services and the contents presented in their web sites. The study then analyzed the content of web pages describing the services provided by 31 Research Universities/Very High research activity determined based on the Carnegie Classification. The analysis was based on 9 components of the services suggested by previous studies, including (1) DMP support; (2) File organization; (3) Data description; (4) Data storage; (5) Data sharing and access; (6) Data preservation; (7) Data citation; (8) Data management training; (9) Intellectual property of data. As a result, the vast majority of the universities offered the service of DMP support. More than half of the universities provided the services for describing and preserving data, as well as data management training. Specifically, RDM services focused on offering the guidance to disciplinary metadata and repositories of relevance, or training via individual consulting services. More research and discussion is necessary to better understand an intra- or inter-institutional collaboration for implementing the services and knowledge and competency of librarians in charge of the services.

세계가 일일 생활권화 됨과 더불어 국제교류가 활발해지므로써 횡문화 간호 연구는 전문직 간호(Professional Nursing)에 있어서 매우 중요한 부분을 차지하고 있음을 많은 문헌을 통해서 알 수 있다(Brink, 1976 : Leininger, 1977 : Roberston & Boyle, 1987). 횡문화 간호연구는 서로 다른 문화적 배경을 가진 사람들을 잘 이해하고 그들의 건강을 돌봄에 있어서 더욱 효과적이고, 안전한 간호를 할 수 있을 뿐만 아니라 간호이론 개발, 간호모형(Model) 개발에 있어서도 매우 중요한 역할을 한다고 믿는다. 본 연구는 1984년에서 1987년 사이에 전문적 간호연구지에 실린 10편의 횡문화 간호연구와 관련된 논문들을 발췌하여 간호지식체의 본질적인 과정인 비판적 문헌고찰을 통해 각 논문들을 비교 분석 한 것으로써, 미래의 간호연구를 위한 간호실무, 간호교육, 간호연구 방법 및 간호 행정면에서 그 적용성을 높여줄 것이다. 비판적 문헌고찰을 위한 기준은 Burns와 Grove(1987)의 방법을 참고하여 아래와 같이 선정하였다. 1. 분석대상 : 목적, 가설 진술, 문헌고찰, 표본조사, 방법론적 논점, 결과 해석 2. 이론적 틀의 유도 흑은 통합 3. 발전적인 간호수행을 위한 중요성, 적용성 및 제언 이상의 내용으로 비교 분석을 해본 결과 1984년에서 1987년 사이에 발표된 횡문화 간호에 관한 논문들의 주제는 주로 여성을 대상으로 한 건강돌봄, 자가간호, 건강신념, 수유, 임신 그리고 간호사와 소수민족 노인과의 의사소통 양상 등으로 나누어 볼 수 있었다. 이론적 틀은 주로 사회학, 정신심리학, 인류학 이론으로부터 도출되었고, 오직 두 편만이 간호 이른에 틀을 둔 것으로 나타났다. 1. 10개의 논문의 가설과 목적의 분석에 있어서 4편의 논문은 목적과 가설이 구체적으로 진술되어 있었고, 나머지 6편은 목적이 전반적으로 진술되어 있었으며 가설도 구체적이지 않았다. 이러한 제한점은 각 논문의 연구자가 문헌고찰을 충분히 하지 못하고 단지 수편의 논문만을 제시 한 데서 비롯되었다고 분석 해 볼 수 있겠다. 2. 문헌고찰 부분에서는 각각의 연구주제를 지지해줄 수 있는 문헌들이 충분히 고찰되지 못하였고, 이론적배경 또한 횡문화 이론과의 관련성이 적었다. 또한 횡 문화 연구에 기초가 되는 연구대상자의 사회 인구학적 특성과 역사적 배경은 잘 나타났으나, 이론적 연구와 경험적 연구 간에 괴리가 있었다. 3. 표본추출방법은 문화에 기반을 둔 대상자를 선정한다는 점에서 한계성 이 있었다. 4. 방법론적 이유로는 대상자와의 면담시간이 구체적으로 기술되지 않았으며, 고유한 언어를 통역하는 과정에서 의미론적 문제에 대한 고려가 부족하였다. 면접과 기록과정에서 보면 자료의 기록과정과 분류 및 분석과정이 명시되어 있지 않았다. 참여관찰과 면접방법을 사용시 이에 대한 자세한 기술이 되어 있지 않았다. 5. 연구결과의 적용 및 이에 대한 논의는 상당히 제한되어 있었는데, 수편의 연구만이 방법론 문제점과 앞으로의 연구분야에 대한 전망을 제시하였으며, 특이한 것은 어 떤 연구자도 이른 개발을 위한 적용 및 임상실무적 차원에서 간호에 대한 제언을 하지 않았다.

The purpose of this study is to present the functional and technical solutions for text learning of web-based textbook in which each letter has its own focal point. The solutions help learners not to lose the main focus when eye moves to the next letter or line. The text screen of the electronic textbook automatically scrolls the text to up and down or left and right directions which are preassigned by learner. It doesn't need the operation of mouse or keyboard. And learner can change scroll speed and types anytime during scrolling. Automatic text scroll function is a solution for controlling data and screen to reflect the personal favor and ability. It contains the content structure of the text(characteristics, categorizations etc.), the appearance of the text(density, size, font etc.), scroll options(scroll, speed etc.), program control type(ram resident program etc.), and the application of the screen design principles(legibility etc.). To resolve these functional problems, technical 8 phases are provided, which are environment setting, scroll option setting, copy, data analysis, scroll coding, centered focus coding, left and right focus coding, implementation. The learner can focus on text without dispersion because the text focal points stay in the fixed area of screen. 1bey read the text following their preferences for fonts, sizes, line spacing and so on.

The study aims to examine the UCC (User Created Contents) Copyright which use the broadcasting contents. UCC are classified by UGC(User Generated Contents), UMC(User Modified Contents), and URC(User Recreated Contents). Especially UMC and URC correspond to a problem of copyright. Following the Copyright Protection Center investigation in 2006, it reported that 83.7% UCC are infringement of copyright. In spite of remarkable the UCC copyright problem, the concrete resolution does not exist. Also it is difficult to apply the offline legal conformity because of online nature of the UCC. The study observes the UCC copyright dispute instances which use the broadcasting contents and investigates a resolution of the UCC copyright. Considering the online media nature, it tries to analyse CCL(Creative Common License) as the ODR(online Dispute Resolution). It is meaningful to search the possibility of UCC copyright problem through the online technical embodiment.

The demand and interest in big data analytics are increasing rapidly. The concepts around big data include not only existing structured data, but also various kinds of unstructured data such as text, images, videos, and logs. Among the various types of unstructured data, text data have gained particular attention because it is the most representative method to describe and deliver information. Text analysis is generally performed in the following order: document collection, parsing and filtering, structuring, frequency analysis, and similarity analysis. The results of the analysis can be displayed through word cloud, word network, topic modeling, document classification, and semantic analysis. Notably, there is an increasing demand to identify trending topics from the rapidly increasing text data generated through various social media. Thus, research on and applications of topic modeling have been actively carried out in various fields since topic modeling is able to extract the core topics from a huge amount of unstructured text documents and provide the document groups for each different topic. In this paper, we review the major techniques and research trends of text analysis. Further, we also introduce some cases of applications that solve the problems in various fields by using topic modeling.

3D video is regarded as the next generation contents in numerous applications. The 2D-to-3D video conversion technologies are strongly required to resolve a lack of 3D videos during the period of transition to the full ripe 3D video era. In 2D-to-3D conversion methods, after the depth image of each scene in 2D video is estimated, stereoscopic video is synthesized using DIBR (Depth Image Based Rendering) technologies. This paper proposes a novel depth fusion algorithm that integrates multiple depth cues contained in 2D video to generate stereoscopic video. For the proper depth fusion, it is checked whether some cues are reliable or not in current scene. Based on the result of the reliability tests, current scene is classified into one of 4 scene types and scene-adaptive depth fusion is applied to combine those reliable depth cues to generate the final depth information. Simulation results show that each depth cue is reasonably utilized according to scene types and final depth is generated by cues which can effectively represent the current scene.
