  • 게임이 산업화된 1970년대 이후 게임의 정의를 통하여 그 속성을 연구하려는 노력이 계속되어 왔으며, 본 연구는 Katie Salen과 Eric Zimmerman이 통합적으로 정리한 규칙, 목표, 갈등, 활동, 의사결정, 자발성, 예술성 등 7개의 게임속성에 대하여 AHP 이론에 근거하여 그 중요도를 분석하였다, 이를 위하여 게임업계 전문가를 통한 게임 속성에 대한 쌍대비교 설문을 실시한 후 데이터를 분석하였으며, 게임이용자 등을 대상으로 하는 2차 설문을 통하여 그 결과가 분석모델과 일치함을 확인하였다. 게임속성의 중요도를 분석한 결과, 위에서 언급한 7개의 요인 중 목표(24%)의 중요도가 가장 큰 것으로 나타났으며, 예술성(16%), 자발성(15%), 규칙(13%) 등이 그 뒤를 잇고 있다. 이는 게임개발에 있어서 게임 이용자가 수행해야할 목표를 분명히 제시하는 것과 아울러 이펙트 등의 영상효과를 크게 고려해야 함을 암시하는 것으로, 본 연구는 게임 개발에 있어서 우선적으로 고려할 속성이 무엇이며 그 중요도는 얼마나 되는가를 체계적으로 규명하였다.

  • Regular monitoring on experimental animal management found the fluctuation of ART outcome, which showed a necessity to explore whether superovulation treatment is responsible for such unexpected outcome. This study was subsequently conducted to examine whether superovulation treatment can preserve ultrastructural integrity and developmental competence of oocytes following oocyte activation and embryo culture. A randomized study using mouse model was designed and in vitro development (experiment 1), ultrastructural morphology (experiment 2) and functional integrity of the oocytes (experiment 3) retrieved after PMSG/hCG injection (superovulation group) or not (natural ovulation; control group) were evaluated. In experiment 1, more oocytes were retrieved following superovulation than following natural ovulation, but natural ovulation yielded higher (p < 0.0563) maturation rate than superovulation. The capacity of mature oocytes to form pronucleus and to develop into blastocysts in vitro was similar. In experiment 2, a notable (p < 0.0186) increase in mitochondrial deformity, characterized by the formation of vacuolated mitochondria, was detected in the superovulation group. Multivesicular body formation was also increased, whereas early endosome formation was significantly decreased. No obvious changes in other microorganelles, however, were detected, which included the formation and distribution of mitochondria, cortical granules, microvilli, and smooth and rough endoplasmic reticulum. In experiment 3, significant decreases in mitochondrial activity, ATP production and dextran uptake were detected in the superovulation group. In conclusion, superovulation treatment may change both maturational status and functional and ultrastuctural integrity of oocytes. Superovulation effect on preimplantation development can be discussed.

  • Background: This paper describes a simple-to-use and reliable screening tool called Critical Task Exposure Screening (CTES), developed by a chemical company. The tool assesses if the exposure to a chemical for a task is likely to be within acceptable levels. Methods: CTES is a Microsoft Excel tool, where the inhalation risk score is calculated by relating the exposure estimate to the corresponding occupational exposure limit (OEL) or occupational exposure band (OEB). The inhalation exposure is estimated for tasks by preassigned ART1.5 activity classes and modifying factors. Results: CTES requires few inputs. The toxicological data, including OELs, OEBs, and vapor pressure are read from a database. Once the substance is selected, the user specifies its concentration and then chooses the task description and its duration. CTES has three outputs that may trigger follow-up: (1) inhalation risk score; (2) identification of the skin hazard with the skin warnings for local and systemic adverse effects; and (3) status for carcinogenic, mutagenic, or reprotoxic effects. Conclusion: The tool provides an effective way to rapidly screen low-concern tasks, and quickly identifies certain tasks involving substances that will need further review with, nevertheless, the appropriate conservatism. This tool shows that the higher-tier ART1.5 inhalation exposure assessment model can be included effectively in a screening tool. After 2 years of worldwide extensive use within the company, CTES is well perceived by the users, including the shop floor management, and it fulfills its target of screening tool.

  • Following a joint OECD/NEA-IAEA-sponsored meeting to define the current role and future perspectives of the application of Computational Fluid Dynamics (CFD) to nuclear reactor safety problems, three Writing Groups were created, under the auspices of the NEA working group WGAMA, to produce state-of-the-art reports on different aspects of the subject. The work of the second group, WG2, was to document the existing assessment databases for CFD simulation in the context of Nuclear Reactor Safety (NRS) analysis, to gain a measure of the degree of quality and trust in CFD as a numerical analysis tool, and to take initiatives to extend the existing databases. The group worked over the period of 2003-2007 and produced a final state-of-the-art report. The present paper summarises the material gathered during the study, illustrating the points with a few highlights. A total of 22 safety issues were identified for which the application of CFD was considered to potentially bring real benefits in terms of better understanding and increased safety. A list of the existing databases was drawn up and synthesised, both from the nuclear area and from other parallel, non-nuclear, industrial activities. The gaps in the technology base were also identified and discussed. In order to initiate new ways of bringing experimentalists and numerical analysts together, an international workshop -- CFD4NRS (the first in a series) -- was organised, a new blind benchmark activity was set up based on turbulent mixing in T-junctions, and a Wiki-type web portal was created to offer online access to the material put together by the group giving the reader the opportunity to update and extend the contents to keep the information source topical and dynamic.

  • As interest in skin care increases, this study aims to contribute to the development of the beauty self-care market by providing basic data through the measurement of the oil and moisture skin condition of women in their 20s and 30s. The study was conducted from November 27, 2020 to January 31, 2021, with 20 women in their 20s and 30s divided into 4 groups, A~D, by age, 5 per group. Skin measurements were taken four times at 4 hour intervals at 0H, 4H, 8H, and 12H based on the first measurement that was taken within 30 minutes after waking up, and the oil and moisture indices were observed over time. As a result, both T and U zones showed significant differences in moisture levels over time, with no difference between groups for both T and U zones. Moisture decreased the most between 0H to 4H, and moisture changed the least between 4H to 8H. Changes in moisture increased the similar at 0H and 12H. The oil condition changed more irregularly compared to moisture over time, but all groups showed lower oil content in the U-zone compared to the T-zone. Overall, the facial oil and moisture conditions of women in their 20s and 30s changed over time, indicating that the skin changes in real time. The fact that the skin data, which was measured in the primary activity living environment, can be used as basic research data in the beauty self-care market is meaningful.

  • The history of modern design begins with the arts and crafts movement(1860). The importance of the movement which decorated the outset gave birth to all the trends of thought which would occur under the circumstances within it, and is deemed that the ideas of the figures who played an active part in the movement might be ceaselessly continued through the works and ideas of their outstanding juniors or purpils as a doctrine of the philosophy of design. Therefore, it might be a prerequisite that the significance and spirit of the movement, and its developing process should be addressed in detail in the first place, but for the limited space of this paper, it was intended to desvribe only the part which can be interpreted in duplicate, linked with post-impressionism. The subject of this thesis is about a theory of art in which both ideas of the movement(1860) and the post-impressionism(1910) are comparatively reviewed. The genre, strictly speaking, is classified into the history of painting, and there is a gap fo about an half century between the issues which are comparatively discussed here. Both the movements began in a same environmental place of England, specially the movement at Milieu in England, and since there is a common point that the representative runners of each movement, William Morries(1834-1896) and Roger Fry(1866-1934), belong to a same race of Engol-Saxon, their ideas coincide with an aesthetic scholar, H. Tanie's aesthetic interpretation method and the more important is, as being elucidated in the comment and aesthetic theory for which Roger Fry gave effort and activity in his later life, that when he read intensively Ruskin's books, $\ulcorner$Modern Painters$\lrcorner$and$\ulcorner$Stones of Venice$\lrcorner$he had solidified his idea of post-impressionism while giving approval and criticism on them. After all, as in a co-painter, Windyham Lewis's reference of 'Roger Fry's Too Late Morris Movement', he, inspired by the actual activities of Morris, played activities similar to that of Morris in which exhibiting and selling some of his decorative art works signed by him and the works of post-impressionism through (1913-1920). Herein, that is wished to add a remark by this author is a point that the author of$\ulcorner$Vision and Design$\lrcorner$, Roger Fry, has not be made a subject of discussion specially in the Korean world of design. So, with this case of a thesis, it's wished that many latent awakened, design persons in korea give efforts to researching into Roger Fry so that their findings could be officially announced in the would. By the way, what is tried to describe in this paper from now on is to analyse and review the origin of post-impressionism which idea was first coined in the art world through the 1st and 2nd exhibitions of 'Manet and Post-impressionism' which were opened each at the Grafton Gallery in 1910 and 1913 by him. And also, it is intended to review it through the art journals and some references by critics of the day in which favorable criticism or severe criticism were ready to comment through the opinions and influences of the coworkers of Roger Fry, say, Clive Bell, Desmond Maccarthy, etc. and of himself as a main axis, on the art ideas of Gauguin, Gogh, Matisse, and Cezanne whose works were the typical ones participated and exhibited in those 1st and 2nd exhibitions.
