최근 반도체 회로의 미세화로 인해 디자인 공정이 20 nm 이하로 내려갔다. 그 결과 회로간의 간격이 줄었으며 많은 문제가 발생 한다. 첫 번째 문제는 미세하게 여러 박막 층들을 쌓기 때문에 박막 층이 그전 50 nm 공정에 비해선 쉽게 무너질 수 있다. 따라서 하나의 박막 층은 다른 여러 박막들의 하중을 잘 견뎌야 할 것이다. 결과적으로 회로의 미세화에 따라 박막의 기계적 특성이 좋아야 될 것이다. 또 다른 문제는 너무 좁은 회로의 간격으로 인해 다른 회로에 영향을 미치는 크로스토크라는 전기적 문제이다. 크로스토크가 크다는 것은 회로간의 누설 전류가 크다는 것을 의미하며 그만큼 신호 전달 능력이 감소 한다는 것을 뜻한다. 크로스토크의 문제점을 해결하기 위해 회로 사이에 절연 막을 만들어 누설전류를 막아야 한다. 이러한 문제를 바탕으로 본 연구는 Zirconium nitride (ZrN) 박막이 이러한 문제점을 해결 할 수 있는 지연구해 보았다. 박막 제작 시 변화 요인은 질소유량 과 열처리 온도 이며 질소유량 변화는 2 sccm 과 8 sccm 두 경우로 하였다. 또한 열처리는 As-deposited state, $600^{\circ}C$ 와 $800^{\circ}C$로 열처리 하였다. 박막 증착은 RF magnetron sputtering을 이용하였으며 열처리는 질소 분위기에서 furnace를 이용하였다. 기계적 특성분석 결과 질소유량이 2 sccm 인 박막의 hardness는 as-deposited stste에서 18.8 GPa이고 $600^{\circ}C$에선 18.4 GPa로 거의 비슷하고 $800^{\circ}C$ 열처리한 경우는 15.4 GPa 으로 hardness가 감소하는 것을 알 수 있었다. 질소 유량을 8 sccm 흘려주며 증착한 박막의 경우는 as-deposited state, $600^{\circ}C$, $800^{\circ}C$에서의 hardness가 각각 17.5, 16.4, 21.1 GPa 으로 감소하다가 증가하는 경향을 보였다. 또한 zrN 박막의 전기적 특성인 누설 전류 밀도도 측정하였다. 결과적으로 본 연구는 ZrN 박막의 질소 유량 변화와 열처리에 따른 기계적, 전기적 특성변화를 확인 하였다.

This study aims to investigate the experiences of librarians/staff members who are responsible for facilitating makerspaces in public libraries, including their works and core competencies, their needs and experiences of training, and future plans in makerspaces. To do that, we carried out semi-structured interviews with 11 librarians/staff members and 1 library director from 7 public library makerspaces. Findings show that the participants received financial supports from the government agencies or/and relied on their library budget to run makerspaces. They identified competencies such as technology literacy, domain knowledge, teaching/programming, willingness to learn and curiosity, communication skills, leadership, and design-thinking. They have future plans for expanding spaces, purchasing equipments, program development, and so on. We believe findings could be useful for those who currently manage or plan to implement a public library makerspace by understanding practical issues and training needs in makerspaces.

Socially Intelligent agent is the agent not only having the ability to recognize and to process human affect through learning and adaptation, but also having human-like social intelligence. By making human feel familiar with the computer, the agent is expected to enhance human-computer interaction (HCI) by providing users with the personalized services and interfaces. This paper proposes the framework for socially intelligent agents behaving socially according to the emotions recognized by ID3 algorithm and psychological OCC model. Also, the agent could process with the emotion to make socially intelligent response through three layered affect functioning model. Finally, the proposed agent can be applied for the development and application of socially intelligent agent in wide areas as the agent framework having similar affect and cognitive structure with human being.

Providing reliable and high quality information sources will be one of the basic skills of librarians in the future. Therefore, this study proposed evaluation criteria for health-related information sources based on a survey of public and medical librarians. As a result, a total of 21 items were selected as evaluation items, in three groups. The first, the health information content group, had 13 evaluation items, including accuracy, recency, medical expertise, regular updates, consideration of audience, objectivity, ease of understanding, plain (non-scientific or technical) language, completeness, relevance to the topic, verifiability, citation of information sources, and specification of precautions or warnings. The second group, the health-information sources group, had 5 evaluation items including clarity of health information for achieving its purpose, clarification of the responsibility of health information, compliance to the privacy policy, fairness of health information providers, and ethics of health information providers. The third group was the health-information website design group, and featured 4 evaluation criteria: ease of access, search capabilities, website ease of use, and query-response services.

In 21 century, Game industry became one field of the cultural content industries. Also, It is one of the most important technologies as a Multimedia, 3-D sound, virtual reality field, and character industry and its scale and effect are getting big. But Korea still lags behind America and Japan in developing game. For that, many support business progressed. However, Special importance〔emphasis〕 is attached to the developing of software engines. In the mean time, The game market of children(under 8) is the biggest one, which form over 30% of all the markets in the PC game market of America. The Children's game, which has both entertaining and educating, is a content-concerned industry. So with a short period of the developing time, they make a high value added. In this paper, 1 study the existing computer games and propose for game contents and the game factor's abstraction suited to the character by kid age. It is concluded that 'Asports', 'Asim,' 'U.J RPG', 'S＋RPG' are beneficial to the child growth on each stage, through serveys analysis of protocol, and research of the cjaracters of the growth on the each age.

The number of youth smartphone users has been increasing, and they use smartphone applications to satisfy their various types of information needs. Nevertheless, few researchers have addressed youth information behavior on applications. In this study, the author examined the application use behavior of youth in response to their work- and everyday life- information needs. The author collected 114 completed questionnaires from students enrolled in a middle school and a high school. The survey results show that participants' usage and perception of smartphone applications were high, and they were using information, entertainment, and communication applications to meet their information needs. In particular, their preference for application use differed by the type of information needs. Also, participants were considering cost, easiness, privacy policy, review, information quality, providers, interface design, and recommendation to choose applications. This study confirms the role of smartphone applications as an influential information source, and it also provides useful implications for educators and for application developers.

Meshes are the most appropriate data structures for representing 3D geometries. Surface meshes have been frequently used for representing 3D geometries, which only samples data on the surfaces of the given 3D geometries. Thanks to the improvements of computing powers, it is required to develop more complicated contents which utilize the volumetric information of 3D geometries. In this paper, we introduce a novel volumetric mesh libraries based on the half-face data structure, called OpenVolMesh, and describe its designs and implementations. The OpenVolMesh extends the OpenMesh, which is one of the most famous mesh libraries, by supporting volumetric meshes. The OpenVolMesh provides the generic programming, dynamic allocations of primitive properties, efficient array-based data structures, and source-level compatibility with OpenMesh. We show the usefulness of the OpenVolMesh in the developments of 3D volumetric contents with prototypic implementations such as volumetric mesh smoothing and CW-cell decompositions.
