최근 컴퓨터 게임에 등장하는 NPC(Non-player Character)에 각종 인공지능 기법을 적용하는 연구들이 이루어지고 있다. 하지만 대부분의 연구가 플레이어를 상대하는 적대적 입장의NPC들의 움직임 조절에 초점을 맞추고 있고 아직까지 게임 상에서 등장하는 모든 NPC는 항상 같은 말과 비슷한 행동을 되풀이하는 모습만을 보여주고 있다. 이는 플레이어가 게임을 비현실적으로 느끼게 만들고 결과적으로 게임의 재미를 저하시키는 요소로 작용한다. 플레이어에게 보다 현실적인 게임 환경을 제공하기 위해서는NPC가 단순히 게임의 배경을 구성하는 오브젝트가 아니라 다양한 대화를 통해 플레이어에게 많은 영향을 주게 하여 게임의 기여도를 높여주어야 한다. 본 논문에서는 이를 위해 게임 속에서 주어지는 퀘스트를 구성하는 NPC, 몬스터, 보상 등의 속성 정보를 온톨로지화 하고, 인터넷에 존재하는 게임 커뮤니티에서 퀘스트 질의/응답 게시판의 글을 추출하여, 플레이어의 관련 질의에 응답하는 NPC를 구현하고자 한다. 이를 위해 온톨로지 정보를 이용한 검색 알고리즘을 구현하였고,시뮬레이션을 통해 NPC가 커뮤니티 게시글 정보를 이용하여 유저에게 고정되지 않은 다양한 메시지를 전달하면서 동시에 유저의 게임 진행을 도와주는 모습을 확인하였다.

The aim of this study was to investigate the synergistic anti-inflammatory and anti-dermatitis effects of grape branch extract (GBE) and Pleurotus eryngii (PEE) combinations on the active immune cells and atopic dermatitis-like skin lesions in mice. The results showed that the combination of GBE ($12.5{\mu}g/mL$) and PEE ($500{\mu}g/mL$) led to much stronger inhibitory effects on the production of inflammatory mediators, such as NO and $PGE_2$ than that exhibited by GBE ($25{\mu}g/mL$) and PEE ($1000{\mu}g/mL$) alone, even at higher concentrations, in LPS-stimulated RAW 264.7 macrophages. The combination of GBE and PEE synergistically inhibited the production of TNF- and IL-6 in LPS-stimulated RAW 264.7 macrophages and PMA plus A23187-activated HMC-1 cells. Furthermore, combined GBE and PEE had a stronger ameliorative effect than GBE and PEE alone by inhibiting the clinical sores, IgE, and IL-4 on atopic dermatitis-like skin lesions in mice. Collectively, these results suggested that the combination of GBE and PEE produced a synergistic anti-inflammatory and anti-atopic dermatitis effect on immune cells and atopic dermatitis-like skin lesions in mice.

This paper aims to design and implement a robot that will help teach children living habits and English conversation education in dual-income families using the open platform robot Q.bo one based on raspberry pi3 of a single board computer. The first function of life habit formation is to help children to wash their hands, to brush their teeth, homework and sleep regularly. The child is then photographed listening to the notification and acting so that the parent can identify and provide feedback. The second basic conversation education feature uses Google's DialogFlow to help children learn English naturally through simple English conversation through the robot. The two-functioning robot allows children from working families to feel secure by printing their parents' voices even when they are not at home. At the same time, it allows them to get into basic lifestyle, to have basic English conversation with robots, and to be interested in English early.

The country with a relative abundance of human capital conducts relatively more R&D in the steady state than its partner. This country acquires the know-how to produce a relatively wider range of innovative goods. High technology comprises a large share of the national economy in the human-capital rich country and real output growth is faster. This prediction would seem to accord weakly with empirical observation of Korean economy.

Shield method is the tunnel boring method that propels a steel cylinder in the ground and excavates tunnels at once. After Marc Isambard Brunel started using the method for the Thames Riverbed Tunnel excavation in London, many kinds of TBM (Tunnel Boring Machine) developed and applied for the construction of road, railway, electricity channel, pipeline, etc. In comparison with NATM concept that allows to observe ground condition and copes with difficulty. The machine selected before starting construction is not able to be changed during construction in shield TBM. Therefore the machine should be designed based on the ground survey result and experiment, so that the tunnel might be excavated effectively by controlling penetration speed, excavation depth and cutter head speed according to the ground condition change. This research was conducted to estimate penetration depth, excavate speed, wear of disc cutter on Boondang Railway of the Han Riverbed Tunnel ground condition by TBM performance prediction models such as NTNU, $Q_{TBM}$, Total Hardness, KICT-SNU and compare the estimated value with the field data. The estimation method is also used to analyze the reason of poor excavation efficiency at south bound tunnel.

Tourism is being used as a tool to regenerate declining spaces. Therefore, the government is carrying out various projects to create tourist attractions to revitalize the traditional marketplace, which is declining nationwide. Because of these government-led projects, traditional marketplaces have been transformed into tourist attractions, and some markets have received enough positive feedback that they have been successfully revitalized economically. However, as marketplaces have become tourist destinations, negative views about government support projects are also increasing. This also leads to conflicts due to differences in perception and interests of stakeholders. This paper examines the process of the marketplace becoming a tourist destination focused on the Tongin Market, in Seoul which has been regenerated as a tourist attraction through a government support project. The purpose of this study is, first, to examine the background of tourist markets becoming tourist attractions and the issues surrounding them. The second was to explore in depth the types of conflict perceptions of visitors, residents and tourists, and the perception of their responses. As a research method, the process of the revitalization of traditional markets through news and existing literature, issues and the difference of perceptions about tourist-centric traditional marketplaces were examined. In addition, the Q methodology was used, which is a qualitative research methodology that can measure the difference of viewpoints and perceptions of specific events in order to analyze the difference of perception among visitors in traditional marketplaces. The results of the study show that there are three main perspectives of difference among visitors' perceptions about government support projects in traditional marketplaces and the marketplace becoming a tourist attraction. The 'policy dependent perspective' emphasizes the necessity of government regulations, a 'critical perspective' criticizes the government's traditional marketplace support policy, and the 'neutral perspective' acknowledges the need for government-led projects and accentuating the internal competitiveness of the marketplace. The study provided the environment for academic discussion about traditional marketplaces, which are becoming tourist attractions nationwide. In addition, this paper can contribute to providing implications for future government projects by analyzing the perception of marketplace visitors.
