Akabane disease is transmitted through mosquitoes in cattle, sheep and goats. It shows congenital abnormalities including encephalomyetitis, hydranencephaly, neurogenic arthrogryposis, and deformed neonatal calves. Akabane viruses, 93FMX and K-9 strain, were isolated from fetal matrix of aborted cow and blood of healthy cow, respectively. S gene sequences of 93FMX and K-9 showed 100% homology with that of OBE-1 strain isolated in Japan. Based upon our sequencing data, we synthesized specific primers for PCR diagnosis. Using these primers, we were able to amplify the S gene of Akabane virus not only from the culture fluid of Vero cells but also from the brain tissue of suckling mouse inoculated with, Akabane virus. These PCR products were confirmed by Southern blot hybridization. Not only the sensitivity of PCR test was high enough to detect the viruses of $10^{1.0}TCID_{50}/ml$, but also the time for diagnosis was significantly shorter than that of the virus isolation by tissue culture method. This method was also effective for the detection of Akabane virus in the cerebrum of fetus. RT-PCR method may be used for a useful diagnostic test of the clinical cases of Akabane disease.
Wii-Fit Plus를 이용한 복합운동프로그램이 65세 이상 노인의 낙상관련 체력요인에 미치는 영향
조재진(Cho, Jae-Jin),엄기매(Um, Ki-Mai),임종민(Lim, Jong-Min) 한국체육과학회 2016 한국체육과학회지 Vol.25 No.4
The purpose of this study is to investigate effects of complex exercise with Wii-Fit Plus including muscle strength, endurance, flexibility for fall-related physical factors in the over 65 elderly. Twenty participants who had no any physical, psychological problems were randomly divided into two groups; Virtual Complex Exercise (VCE) group (77.3 ± 5.62 year) and Virtual Balance Exercise (VBE) group (80.8 ± 5 .14 year). VCE group p articipated in 5 w eeks of v irtual complex e xercise program, c onsisted o f balance, strength, endurance and flexibility for fall-related with Wii-Fit Plus. VBE group participated in 5 weeks of virtual balance exercise program, consisted of balance for fall-related with Wii-Fit Plus. Low extremity Senior Fitness Test was used for evaluation of fall-related physical factors in this study. Gait and balance function was evaluated by Performance-Oriented Mobility Assessment(POMA) scale at preand post-intervention. After 5 weeks, VCE group showed significant improvement on 30-second chair stand test, 2-minute step test, POMA scale. VBE group showed significant improvement on 30-second chair stand test, POMA scale. No significant differences were observed in chair sit and reach test at before and after intervention in between two groups. But significant difference was observed in 2-minute step test at before and after intervention in between two groups. We found that virtual complex exercise program improved fall-related physical factors excluded flexibility. Also virtual balance exercise program has positive effects on low extremity strength, gait and balance functions. On basis of these results, we concluded that Virtual Complex Exercise is effective on strength, especially endurance, gait and balance functions for fall-related physical factors in the over 65 elderly people.

The purpose of this study is to investigate effects of isokinetic exercise on shoulder external and internal rotator strength and shoulder function in patients with shoulder impingement syndrome. Twelve patients who were diagnosed shoulder impingement syndrome were randomly divided into two groups; a isokinetic exercise (IE) group (55.3 ±18.16yr) and a Home exercise (HE) group (52.83±26.27 yr). IE group participated in 5 weeks of isokinetic exercise, consisted of strengthening program on shoulder external/internal rotator with maximal isokinetic contraction. Both groups were educated and conducted home based exercise for 5 weeks. HE group participated in only home based exercise. The shoulder ortator cuff strength was measured by isokinetic strength evaluation machine and shoulder function was evaluated by the University of California at Los Angeles scale(UCLA scale), Shoulder Pain and Disability Index(SPADI) score at pre- and post- intervention. After 5 weeks, IE group showed significant improvement on external rotation peak torque(p<.05), external/internal rotation total work(p<.05). But HE group showed no significant improvement on rotator cuff strength (p>.05). Also IE group showed significant improvement on Shoulder function(p<.05). IE group showed significant improvement on UCLA score (p<.05), SPADI score (p<.05) but HE group only showed significant improvement on UCLA score (p<.05). No significant differences were observed in shoulder rotator cuff strength and shoulder function at before and after intervention in between two groups (p>. 05). We found that isokinetic exercise improved shoulder rotator cuff strength for relatively short period. Also home based exercise has positive effects on shoulder functions. On basis of these results, we concluded that isokinetic exercise is effective on shoulder rotator cuff strength, and shoulder functions in patients with shoulder impingement syndrome. Finally, Home based exercise included rotator cuff strength exercise and scapular stabilization exercise, shoulder stretching exercise would be necessary for treatment of shoulder impingement syndrome.
정지영상에서의 Rolling Shutter 왜곡 현상 보정
조재진(Cho Jae-jin),박능수(Park Neungsoo),이성원(Lee Seong-Won) 한국방송·미디어공학회 2010 한국방송공학회 학술발표대회 논문집 Vol.2010 No.7
최근 휴대기기들의 CMOS 영상 센서의 사용으로 Rolling shutter에 의한 왜곡현상이 발생하고 있다. 이러한 왜곡현상을 보정하기 위한 기존의 방법은 동영상에서의 움직임 정보만을 주로 이용하고 있다. 따라서 본 논문은 움직임 정보를 이용한 보정의 성능을 더욱 좋게 하기위하여 정지영상에서 Rolling Shutter 왜곡현상에 대한 추가적인 움직임 정보를 찾아내고 보정하는 알고리즘을 제안하고 있다.
자동차 Gateway를 위한 Auto Code 생성 Tool 개발
조재진(Jae-Jin Cho),김태현(Tae-Hyun Kim),채창훈(Chang-Hoon Chae) 대한전자공학회 2015 대한전자공학회 학술대회 Vol.2015 No.11
Recently, the number of the ECU is installed in a car. Messages need to increase the communication to the ECU is increasing. Increasing message will increase the gateway development time and the probability errors. In this paper, we introduce the development of a Generation Tool to improve the development efficiency and quality of the Gateway.

Herman Melville is said to have been enamored of "cosmic generalities," but that does not necessarily mean he was unconcerned with political issues. The interpretation of Melville's "Benito Cereno" enters a new phase when it is recognized that the work was based on a real historical incident. But still the meaning of the work is not completely clear. Joyce Adler says "Benito" does not express its meaning openly but hides it in the shadows which are thrown over everything. One of the most helpful symbols added to the original is the heraldic dark satyr which holds its foot on the prostrate neck of a writhing figure. The dark satyr symbolizes the Negro leader Babo, but the roles of Negro and white become interchangeable in the following actions. As Babo chalked the words "follow your leader" below the figure-head, the mate cried the same words when he boarded to recapture the ship. The second most valuable clue in interpreting the work is the changing of the name of the slave ship "Tryal" to "San Dominick." It serves to remind the reader that one of the most terrible black rebellions took place in Santo Domingo in the 1790s. Dominican Friars were notorious for the Inquisition in which more than 2000 Albigenses were killed as heretics in 15th century Spain. Thus the "imputation of malign evil" is shared by all, black and white, and it determines their basic equality and interchangeability. Melville was neither an emancipationist nor a supporter of slavery. Melville said that emancipation has ridded the country of the reproach but not wholly of the calamity. He believed the coexistence of the two races in the South was a grave evil. It is the "deeper shadow" of the future of the U. S. and what Benito means when he says what he most fears is "the negro." We can also see this fear in every ideological or racial conflict in the world today.
