Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 49-65, 2004. The purpose of this study is development of posture evaluation and Range of Motion(ROM) system by using digital vision analysis method. The results of this study are as follows. First, Scoliosis evaluation through this research measurement system represent 3mm error in 7 cervical point and deepest lumbar point, 0.7mm error in other point. This mean this research measurement system have a reliability for scoliosis evaluation. Second, for spine line evaluation on high fat subject, we need reconstrection spine line after mesurement for fat thickness in 7 cervical point and deepest lumbar point. Third, In pedioscope error test, it present 0.01848cm in X axis and 0.01757cm in Y axis. This results mean pedioscope have a reliability foot evaluation. Forth, Posture evaluation and Range of Motion measurement system by using digital vision analysis method can fast measure in range of motion and foot evaluation and posture. therefore we can expect this system application in young people posture clinic center and hospital and so on.

Some basic propeties of suppository bases containing cetyl alcohol(C), lanoline(L), and propylene glycol(P) were investigated in this study. The results were as follows. 1. Suppository could be molded easily in the higher amount of cetyl alcohol than that of lanoline or propylene glycol. 2. Suppository was molded by 28 kinds of different C:L:P ration could be soften in rectum temperature and the proper ratios of C:L:P to release sodium salicylate from suppository were 5:3:1, 3:1:2, 4:3:1, 5:3:2. 3. The softening times of suppository with these ratios of C:L:P were 9 min to 20 min. 4. Softening temperature and time were not changed after storage for 1, 11, 38, 54 days at 20℃ or 4℃ 5. The most appropriate ratio of this base was 5:3:1 in sodium salicylate suppository.

The monthly mean daily global solar radiation and sunshine duration, have been employed in this study to develop correlation model for Daegwallyeong during 2011. The corresponding monthly value of extraterrestrial solar radiation and possible duration of sunshine are calculated for Daegwallyeong meteorological data. Forecasting performance parameters such as coefficient of determination (R2), mean bias error (MBE) and root mean square error (RMSE) are presented as analyzed for the model. The model with multi-linear regression has the highest R2 value of 0.95 and average MBE and RMSE values of −0.11 MJ/m2day and 1.63 MJ/m2day, respectively. The model exhibited negative MBE which shows that the model resulted in underestimation of the global solar radiation relative to the meteorological measured value. The equation could be employed in the estimation of solar radiation at Daegwallyeong, other locations with similar meteorological characteristics.

J. H. Back, S. H. LEE, Y. J. Moon. The kinematical Evaluation of Natural Team's Butterfly Turn motion. Korean Journal of Sport Biomechanics, Vol. 14, No. 1, pp. 117-131, 2004. The foreign superior players and national team players' turning phase was measured, compared and analyzed to help the representative players improve the skill of turn. The underwater video camera used to analyze and evaluate the representative players' skill of turn in detail and the result is as follows. 1. The record for the phase of turn was similar to the rank of the last record. The improvement of the skill of turn was required because Korean players' record was lower than the foreign players' one. In case of 200m events the 1st turn was the fastest and it took more time as the turn is repeated. 2. It shows that the preparation phase and turning motion cause the difference between the players and within one player. 3. The horizontal movement of center of gravity moves to turning point slowly in the preparation phase, does not move nearly in the turning phase and increase again in the propulsion phase. Good record has short time for turn phase. The result means that the shorten the turning phase is the most important factor. Therefore the preparation for this is required. The vertical movement is maintained or increase a little and then move to from the turning phase. 4. The characteristic of horizontal velocity in center of gravity is that there is any big changes at the preparation phase, the faster velocity is found from the better record and the accelerating time is fast at the propulsion phasen. The wrong motion is made by not using the swimming velocity for turning and waiting and more time is required by this. 5. The angle of knee when the player touch the turning point is 106.22435.56 and the maximum angle of knee during the driving after the touch of tuning point is full extension. The size of maximum angle of knee did not match with the required time of propulsion phase. It seems that the individual difference is big when the players touch the turning point the angle of knee and the research for the individual angle which can reveal the maximum power should be carried out. The national team player's skill for the turn is behind the foreign players' one and a lot of problems were found. It shows that the players could not practice the skill for turn during the training. The 1st reason for it is the various facilities like underwater window or analyzing equipment like underwater camera with which the coaches can teach and correct the players' detailed skill. It is need to evaluate the players' detailed skill exactly and correct it by objective data to complete the good skill in the future. In this regard, the investment for the facility is necessary.
Psyllium Husk의 식이섬유 소재로서의 기능성 탐색
이신영,백진홍 강원대학교 산업기술연구소 2005 産業技術硏究 Vol.25 No.B
Dietary powder from Plantaginis ovatae testa was prepared by mechnical milling/grinding of the outer layer of the seed. The crystalline/surface structures of its power (100 mesh) were examined, and several physical functionalities, including, water capacity, oil holding capacity, emulsion/foam properties and physiological functionality such as in-vitro glucose and bile acid retarding effects were investigated. Water holding capacity(WHC) of psyllium powder was 33.71±0.10g water retained/g solid at room temperature, whileas oil holding capacity(OHC) for soybean or rice bran oil were about 1.80g oil retained/g solid. These values of WHC and OHC were about 5.6 times higher and 2.8 times lower than those of commercial a-cellulose, respectively, Changes of pH showed a small effect on WHC, but WHC increased with temperature. Emulsion capacity of 2%(w/v) psyllium was about 60$ level of 0.5%(w/v) xanthan gum but emulsion stability after incubation of 24 hours showed about 1.4 times improvement of xanthan gum(0.5%, w/v). Also, psylliume(above 2%, w/v) alone had higher foam capacity than that of xanthan(1.1 times) and expecially, 1 or 2% addition of psylluim improved the foam stability of protein solution(1% albumin+0.5% CaCl_(2)) by factor of 3.3 and 6.0 times, respectively. The glucose and bile acid retarding effects of psyllium powder were relatively very excellent suggesting the prevention from diabetes and arteriosclerosis. Especially, psyllium showed the 3.7 and 3.3 times higher effect on in-vitro glucose and bile acid retardation than those of commercial a-cellulose, respectively.

가온 가압법에 의하여 합성된 Li-EaGICs, Li-EGlCs를 자발적으로 분해시켜서 이들의 deintercalation 과정에 대하여 X-선 회절분석, 열분해분석 몇 전기비저항값을 측정하여 이들 결과에 대하여 토론하였다. Intercalation에 대한 X-선 회절분석 결과에 의하면, Li-EaGlCs와 Li-EGlCs는 1 stage가 완전하게 형성되지 않았고, 주로 저차 stage가 형성되었다. 또한 deintercalation 결과에 의하면, 4주 이후에는 deintercalation이 멈추었으며 Li-EGDICs는 Li-EaGDlCs보다 층간 잔유 금속을 많이 가지고 있음을 알 수 있다. 열분해분석 결과에 의하면 두 가지 화합물 모두 강한 발열반응을 수반하였으며, 또한 400℃ 이 상에서는 반응이 수반되지 않는 것으로 보아 intercalants들이 완전히 deintercalation되었음을 알 수 있다. 전기 비저항 측정 결과에 의하면 Li-EGDICs는 상대적으로 낮은 비저항값을 가지고 있었으며, Li-EaGDICs는 이상적인 비저항 곡선을 나타내었다. 이들 결과로부터 Li-EaGlCs가 Li-EGICs보다 2차 전지의 양극재료로서 더 좋은 성질을 가지고 있음을 알 수 있다.

조원표,조병욱,고백진,이용찬 大韓顎顔面成形再建外科學會 1990 Maxillofacial Plastic Reconstructive Surgery Vol.12 No.3
In the treatment of dentofacial deformities, analysis of skeletal pattern, with evaluation of plaster dental case, is essential procedure. This study was based on 20 patients with dentofacial deformity who were admitted to the department of oral and maxillofacial surgery Kngnam sacred heart Hospital during the period of Jan 1989. We studied serial cephalometric radiogarphs of patients (pre-op, postop immediately, postop 6 moth). The obtained results indicates the good resistance of rigid fixation against relapse in orthognathic surgery.
