기능성 게임은 현재 치료, 의학 관련 검사, 인지발달, 특수훈련 및 교육콘텐츠로서 많은 분야에 적용되고 있 다. 아동을 위해서도 주의, 작업기억, 공간인지 및 협응 능력 등 다양한 인지 및 인지 신경검사와 이런 인지 기능들의 증진을 위해 개발되고 있다. 하지만 놀이의 중요한 기능 중 정서적인 부분이 차지하는 것에 비해 기능성 게임이 보여준 역할은 매우 부족하며 아직 기초적 연구 단계에 머물러 있다. 컴퓨터 게임을 통한 정 서적 상호작용의 학습에 대한 연구와 도전이 시급하다. 본 연구에서는 아동의 정서 지능 측정을 위한 기능성 게임 개발을 목표에 두고 정서지능의 요소 중 하나인 타인의 정서 인식능력을 측정하는 게임을 개발하고자 하였다. 정서적 지능의 기초 요소인 정서인식이 기능성 게임으로 측정되고 나아가 향상될 수 있다면 아동의 정서지능을 위한 기능성 게임에 대한 새로운 가능성들을 여는 계기가 될 것이다. 실험 결과 개발된 정서지능 측정용 기능성 게임의 점수는 정서지능의 하위 요소인 정서인식, 감정이입, 정서활용과 통계적으로 유의미한 정적 상관관계를 나타내었으며, 인지적 처리와 비교적 관련이 많은 사고촉진과 정서통제 요인과는 상관을 보 이지 않았다. 이는 얼굴의 표정을 이용하여 긍정적인 자극에 대한 초등학생들의 정서적 반응을 이끌어내고 이를 게임의 점수로 환산하는 것으로서의 가능성을 잘 보여준다고 볼 수 있다.

Stress can provoke various symptoms in human. It can affect our thoughts, emotion, and behavior. In general, it is necessary but dangerous if we do not control the level. This study tried to develop a game to measure stress level of game-player and verify whether the score measured by the game correlates with stress level measured by self-reported surveys. A simple prototype of game to measure player’s stress level was developed based on Odd-one out experimental paradigm that allow to measure attentional engagement and disengagement in stress people. 50 students and 50 office-workers played the game to measure stress level and the data was analyzed with correlation analysis between stress score measured by the game and that measured by surveys (type-D and perceived stress scale). The results showed that there is significant correlation between two stress scores measured by computer game and the perceived stress scale but no correlation between the stress score measured by computer game and that measured by type-D. This indicate that the game developed based on attentional movement can measure in general stress level related to current concerns but not long-term temperature related to stress. Some limits and precautions of stress measurement with computer game such as reaction time or statistical assumption were discussed.

성인보다 주의 집중력이 낮은 아동의 인지력을 측정하는 것은 매우 어려운 일이다. 기능성 게임은 아동의 동기와 주의집중을 높이는 효과적인 방법으로 아동의 인지력 측정을 위한 좋은 대안이 될 수 있다. 본 연구는 주의력 측정을 위해 사용되는 TMT(Trail Making Test)를 기능성 게임으 로 제작하여 아동의 주의력을 측정하고 그 결과를 검증하고자 하고자 하였다. 이를 위해 기능성 게임으로 제작된 TMT는 주의 속도와 선택적 주의를 측정하는 유형A와 주의 전환을 측정하는 유형B로 설계되었으며, 검사결과를 아동의 학업성취도와 연결하여 검사의 타당도를 검증하고자 하였다. 284명의 아동을 기능성 게임을 통해 주의력을 검사한 결과, 유형A의 반응속도(Reaction Time) 그리고 유형B의 정오율과 학업성취도간 상관이 나타났다. 이러한 결과는 본 기능성 게임이 주의력의 여러 목표한 측정 요소를 잘 반영하고 있음을 시사한다. 기존의 단순한 결과만을 산출 하는 지필검사와는 다르게 본 기능성게임은 주의와 관련된 여러 가지 행동 데이터를 제공해주고, 재미와 집중을 높여 아동에게 보다 긍정적이고 생태학적인 측면이 강화된 인지측정 도구를 제공해 줄 수 있을 것으로 기대한다.

Growth hormone (GH) is obligatory for growth and development. But, there is controversy on the GH effect about reproductive processes of sexual differentiation, pubertal maturation, gonadal steroidogenesis, gametogenesis and ovulation. This study was conducted to investigate the effect of GH on estrus, ovulation and embryo implantation. The results obtained were as follows. GH stimulated to increase estrus rate (p<0.05), pregnancy rate (p<0.05), and total fetus number in mice treated for superovulation. Also, the correlation between GH and steroids, E2 and P4, at peri-estrus stage/ peri-ovulation stage/ peri-implantation stage of the superovulation-induced mice was examined. Consequently, GH co-injected with PMSG especially increased P4 level (p<0.05) at peri-estrus stage of superovulationinduced mice. In conclusion, GH co-treatment in superovulation system boosted the rate of estrus, pregnancy and total fetus by increasing progesterone level at peri-estrus stage of superovulation-induced mice.

To find an alternative for synthetic pesticides, methanol extract from plant samples were tested for their insecticidal activity against insect. The extract of Asiasarum sieboldii had strongly insecticidal activity against Plutella xylostella. Roots of A. sieboldii were extracted with methanol, and the concentrated extract was partitioned with n-hexane, ethylacetate, n-buthanol and H2O. The highest activity was shown in the hexane fraction. Activity-guided fractionation led to the isolation of two amides from hexane fration through the repeated silica gel column chromatographic separations. From the interpretation of spectropic data including NMR, MS, IR, the chemical structures of compounds were determined as dodeca-2E,4E,8Z,10Z-tetraenoic acid isobutylamide and dodeca-2E,4E,8Z, 10E-tetraenoic acid isobutylamide. These compounds showed insecticidal activity on P. xylostella by 96.7% at 100ppm. The liquid formulation controlled on cabbage effectively. The extract and compounds from A. sieboldii showed insecticidal activity against Nilaparvata lugens. As a naturally occurring pesticide, A. sieboldii could be useful as a new botanic insecticide.

Significant advances in mechanical testing for hard materials are discussed in this paper. There are three specific areas that are covered. In the measurement of fracture toughness factors such as the control of slow crack growth to produce strating cracks, and evaluating reproducibility and repeatability of tests have been recently examined. The miniaturization of tests reduces the amount of material that is used in testing, improves the throughput of tests, and also improves cost effectiveness. New techniques such as stepwise testing and micro scratch testing have contributed to significant additions to the knowledge of the wear mechanisms that operate in these materials.

Tumors of the lacrimal gland are uncommon, and most are of epithelial origin. Primary non-Hodgkin’s lymphoma (NHL) of the lacrimal gland is extremely rare. A 45- year-old male was admitted with a complaint of a painless swelling of the right eye superiolateral lesion. We confirmed primary diffuse large B cell lymphoma of the lacrimal gland, and the patient was classified as stage IE. The patient was treated with chemotherapy, followed by radiotherapy. He achieved complete remis-sion, and, after 26 months of follow-up, the patient remained free of disease.
