EasySoft(이하:ES)는 컴퓨터를 처음 배우는 초급자에서부터 프로그래밍 가능자에 이르기까지 다양한 범위의 학습자에게 통합 교과적인 지식을 토대로 알고리즘 교육을 제공하여, 창의성과 논리성 계발의 효과를 거둘 수 있도록 만들어진 학습기자재이다. ES는 EasyLab, EasyC, Visual Basic과 같이 ActiveX를 지원하는 툴과 연동하여 사용한 수 있는 ActiveX 제어도구(EasyOCX)로 구성되어 있다. 학습자는 ES를 통하여 자신의 생각을 구성, 알고리즘화 시켜 프로그래밍하고 코드를 로봇으로 전송하여, 로봇의 움직임과 자신의 의도를 비교, 연구, 반복하는 작업으로 학습하게 된다. ES는 학습기자재가 부족한 교실현장에서 직접 활용할 수 있도록 구성된 것으로, 흥미적 요소와 교육적 요소를 적절하게 조화 시킨 소프트웨어이다. EasyLab은 컴퓨터를 모르는 학습자도 알기쉬운 GUI식 흐름도 기반 S/W를 표방하므로 초등학교에서, EasyOCX나 EasyC의 경우는 EasyLab과 유사한 방식을 추구하되 직접 프로그래밍 하게 되어있어 한 단계 높은 중 고등학교의 교수장면에서 직접 활용이 가능하다.

Unilateral labyrinthectorny (ULX) causes autonomic symptoms, ocular and postural asymmetries, which disappear over tune in the process of equilibrium recovery known as vestibular compensation. In the present study in order to elucidate mechanisms responsible for the effects of electrical stimulation on vestibular compensation and investigate the relationship between vestibular compensation and c-Fos expression in the medial vestibular nuclei following ULX, we measured spontaneous nystagmus, eye movement induced by sinusoidal rotation and c-Fos expression or to 72 hs after ULX in Sprague-Dawley rats. Experimental animals were divided into two groups: ULX group with ULX only, and electrical stimulation (ES) group with electrical stimulation of $-2{\sim}-5V$, 1.0ms, 100 Hz to the lesioned vestibular system for 4 hs/day. Spontaneous nystagmus following ULX disappeared by 72 hs in ULX group and 36 hs in ES group. In eye movement induced by sinusoidal rotation, normal pattern of eye movement by rotation toward the lesioned side was recovered 24 hs after ULX at rotation of 0.1 Hz and 6 hs after at 0.2 Hz, 0.5 Hz in ULX group. In ES group, the eye movement recovered after 12 hs at 0.1 Hz, 6 hs at 0.2 Hz, and 4 hs at 0.5 Hz. Directional Preponderance which represents the symmetry of bilateral vestibular functions showed significantly early recovery in ES group compared with that of ULX group. Expression or c-Fos immunoreactive cells in the bilateral medial vestibular nuclei was severely asymmetrical till 36 hs in ULX group, and then it became a symmetry and disappeared after 72 hs. However, ES group showed the symmetry of c-Fos expression after 6 hs, which was significantly early recovery in 25 group. All these findings suggest that electrical stimulation ameliorates recovery of vestibuloocular reflex following ULX by the restoration of the balance of the resting activity between bilateral medial vestibular nuclei. In addition, c-Fos expression in the medial vestibular nuclei could be used as a marker of vestibular compensation since c-Fos expression is closely related to the course of recovery following ULX.

휴대용 임베디드 기기에서의 삼차원 엔진은 크게 바이트 코드를 실시간으로 해석하며 실행하는 자바 기반의 JSR184와 C언어 기반의 OpenGL/ES가 있다. 이들 두 표준에서 자바 객체를 지원하는 JSR184는 OpenGL/ES에 비하여 상대적으로 많은 프로세서의 자원을 사용하여 제한된 연산능력을 보유하고 있는 임베디드 기기에 적용할 경우 제약이 따를 수 밖에 없다. 반면에 기존 개인용 컴퓨팅 환경에서 사용되는 삼차원 컨텐츠는 자바의 장점을 이용하여 제작되었기 때문에 유럽에서 많은 사용자 층을 확보하고 있고, 또한 그 컨텐츠의 품질이 우수하여 상용 통신망인 GSM 망에서 많이 서비스 되고 있다. 따라서 GSM 망에서 사용되는 휴대용 임베디드 기기에 기존의 자바 기반 삼차원 컨텐츠를 별도의 변환 과정 없이 지원할 수 있는 JSR184의 지원이 필요하지만, 현재 개발되어 사용되는 자바 기반 삼차원 엔진은 휴대용 기기가 보유한 연산능력에 비하여 상대적으로 많은 연산량을 필요로 하기 때문에 상용제품에 적용하기에 많은 어려움이 따른다. 본 논문에서는 휴대용 임베디드 기기가 가지고 있는 충분하지 않은 연산능력을 바탕으로 자바 객체의 장점을 수용하면서 삼차원 컨텐츠의 처리속도를 향상 시킬 수 있는 바인딩 기법을 제안하였다. 제안된 바인딩 기법은 자바를 이용한 삼차원 컨텐츠를 지원하기 위하여, JSR184의 표준 인터페이스를 상위 계층에서 지원하고, OpenGL/ES와 JSR184를 서로 연결하기 위하여 이기종 코드 변환 언어인 KNI(Kilo Native Interface)를 중간 계층에서 사용하였고, 하위 계층에서 OpenGL/ES의 표준을 구현하였다. 제안하는 바인딩 기법은 모의실험을 통하여 기능을 검증하였고, ARM을 장착한 FPGA를 사용하여 그 성능을 평가하였다.

A small body size of Brown Tsaiya laying duck is desirable to reduce maintenance requirements, so the body weight at 40 weeks of age (BW40) has to be maintained at its current level. Egg weight has to be maintained at around 65 g to meet market requirements. Eggshell strength at 40 weeks of age (ES40) must to be increased in order to maintain a low incidence of broken eggs. Thus, number of eggs laid up to 52 weeks of age (EN52) has to be increased without negative correlated response on ES40. A new linear genetic selection index was used: $I_g=a_0{\times}GEW40\;(g)+a_1{\times}GBW40\;(g)+a_2{\times}GES40\;(kg/cm^2)+a_3{\times}GEN52\;(eggs)$ where GEW40, GBW40, GES40 and GEN52 were the multitrait best linear unbiased prediction (MT-BLUP) animal model predictors of the breeding values respectively of egg weight and body weight at 40 weeks of age (EW40, BW40), ES40 and EN52. The coefficients $a_0$, $a_1$, $a_2$ and $a_3$ were calculated with constraints of 0.0 g, 0.0 g and $0.013kg/cm^2$ for expected genetic gains in EW40, BW40 and ES40 respectively and maximum gain in EN52. Since 1997, the drakes and the ducks were selected according to their own indexes, with this new genetic selection index. From G0 to G4, the average per generation predicted genetic responses in female duck were +0.05 g for EW40, +0.92 g for BW40, $+0.035kg/cm^2$ for ES40 and +2.13 eggs for EN52. Which represented respectively 0.07%, 0.06%, 0.67% and 1.0% of the means of the EW40, BW40, ES40 and EN52. For ES40 and EN52, it represented also respectively 16.1% and 21.6% of the additive genetic standard deviation of these traits. Thevse results indicated that selection of laying Brown Tsaiya by a restricted genetic selection index and with MT-BLUP animal model could be an efficient tool for improving the efficiency of egg production, increasing egg shell strength and egg number while holding egg weight and body weight constants.

An enantioselective lipase gene (esf) for the kinetic resolution of optically active (S)-flurbiprofen was cloned from the new strain Serratia marcescens ES-2. The esf gene was composed of a 1,845-bp open reading frame encoding 614 amino acid residues with a calculated molecular mass of 64,978 Da. The lipase expressed in E. coli was purified by a three-step procedure, and it showed preferential substrate specificity toward the medium-chain-length fatty acids. The esf gene encoding the enantioselective lipase was reintroduced into the parent strain S. marcescens ES-2 for secretory overexpression. The transformant S. marcescens BESF secreted up to 217kU/ml of the enantioselective lipase, about 54-fold more than the parent strain, after supplementing 3.0% Triton X-207. The kinetic resolution of (S)-flurbiprofen was carried out even at an extremely high (R,S)-flurbiprofen ethyl ester [(R,S)-FEE] concentration of 500 mM, 130 kU of the S. marcescens ES-2 lipase per mmol of (R,S)-FEE, and 1,000 mM of succinyl ${\beta}-cyclodextrin$ as the dispenser at $37^{\circ}C$ for 12h, achieving the high enantiomeric excess and conversion yield of 98% and 48%, respectively.

The purpose of this study was to determine whether vitamin {TEX}$B_{6}${/TEX} deficiency and age affect the blood cho-lesterol profile in exercising rats. Fifty four rats were fed either a viramin {TEX}$B_{6}${/TEX} deficient dief(-{TEX}$B_{6}${/TEX}) of a control diet(+{TEX}$B_{6}${/TEX}) for 6 weeks, then subdivided into 3 groups:non-exercise group(NE), exercise and sacrifice group(ES), exercise and recuperation group(ER). ES group was exercised in treadmill({TEX}$10^{o}${/TEX}, 0.5~0.8km/h) for 2 hours and sacrifice. ER group was recuperated three days with respective diet after exercise. At week 3 and 6, and level of plasma total cholesterol(TC), high density lipoprotein cholesterol(HDL_C) and low density lipoprotein cholesterol(LDL_C) were compared. In NE group, there was no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats. The plasma levels of TC and LDL_C of 6 weeks were higher than those of 3 weeks and on difference in HDL_V between 3 weeks rats and 6 weeks rats. In ES group, there was also no difference in the levels of TC, HDL_C and LDL_C between +{TEX}$B_{6}${/TEX} rats and -{TEX}$B_{6}${/TEX} rats and there was no difference in TC, LDL-cholesterol between 3 weeks rats and 6 weeks rats. The level of HDL_C pf 6 weeks was lower than that of 3 weeks rats. In ER group, there was no difference in the levels of TC and LDL_C not only between +{TEX}$B_{6}${/TEX} rats and-{TEX}$B_{6}${/TEX} rats but also between 3 weeks rats and 6 weeks rats. The level of HDL_C was lower in -{TEX}$B_{6}${/TEX} rats than in +{TEX}$B_{6}${/TEX} rats and higher in 6 weeks rats than in 3 weeks rats. These results suggest that vitamin {TEX}$B_{6}${/TEX} deficiency may affect the HDL_C during exercise and after recuperation. The desirable effect of exercise on plasma Cholesterol profile is strengthened in adult age than young age.

Background: The bridge exercise targets the gluteus maximus (Gmax) and gluteus medius (Gmed). However, there is also a risk of dominant hamstring (HAM) and erector spinae (ES) muscles. Objects: To analyze the muscle activity the of Gmax, Gmed, HAM and ES during the bridge exercise with and without hip external rotation in different degrees of knee flexion. Methods: Twenty-three subjects were participated. The electormyography (EMG) activity of the Gmax, Gmed, HAM and ES muscles was recorded during the exercise. The subjects performed the bridge exercise under four different conditions: (a) with $90^{\circ}$ knee flexion, without hip external rotation (b) with $90^{\circ}$ knee flexion, with hip external rotation (c) with $135^{\circ}$ knee flexion, without hip external rotation (d) with $135^{\circ}$ knee flexion, with hip external rotation. Results: There was no significant interaction effect between the degree of knee flexion and hip external rotation. There was a significant main effect for degree of knee flexion in Gmax, HAM muscles activity. Gmax muscle activity was significantly greater in the $135^{\circ}$ knee flexion position than in the $90^{\circ}$ knee flexion position (p<.001). While HAM muscle activity was significantly less in $135^{\circ}$ knee flexion position than in the $90^{\circ}$ knee flexion position (p<.001). ES muscle activity was significantly less in the $135^{\circ}$ knee flexion position than in the $90^{\circ}$ knee flexion position (p=.002). The activity of both the Gmax and Gmed muscles was significantly greater with hip external rotation (p<.001 and p=.005, respectively). Conclusion: For patients performing the bridge exercise, positioning the knee in $135^{\circ}$ of flexion with hip external rotation is effective for improving Gmax and Gmed muscle activity while decreasing HAM, and ES muscle activity.

Objective : Ephedra sinica (ES) has has been used as remedy of allergic diseases for a long time in Korea. In the present study, we investigated the anti-allergic effects of ES on experimental allergic asthma mouse model using ovalbumin (OVA). Methods : BALB/c mice were sensitized and challenged with 100 ug of OVA and 1 mg of aluminum potassium sulfate of 0.2 ml phosphate-buffered saline(PBS) intraperitoneally on day 1 and 15. mice were challenged on 3 consecutive days with 5% OVA and AHR was assessed 24 h after the last challenge. we examined the lung histology, airway hyper sensitivity, total inflammatory cell count in bronchoaveloar lavage fluid(BALF), Th2-associated cytokines production and IgE production. Results : ES potently inhibited the lung damage and the development of Penh. ES also reduced the number of BAL cells during OVA-induced allergic asthma. Furthermore, ES inhibited cytokines production such as IL-4, IL-13 productions, and IgE level of serum. Conclusion : These results suggest that ES may inhibit the production of IL-4, IL-13, IgE and infiltration of inflammatory cell and be beneficial oriental medicine for allergic asthma.
