G. S. MOON, The kinematic analysis of the ankle joint and EMG analysis of the lower limbs muscle for the different walking speed. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 177-195, 2005. The purpose of this study was to analyze the kinematic variables of ankle joints and EMG signal of the lower limbs muscle activity for the different walking speed. The subjects were 6 males of twenties. It was classified into three different walking speed-0.75m/s, 1.25m/s, 1.75m/s. The walking performances were filmed by high speed video camera and EMG signal was gained by ME3000P8 Measurement Unit. Tibialis anterior(TA), Gastrocnemius medial head(GM), Gastrocnemius lateral head(GL), Ssoleus(SO) were selected for the dorsiflexion and plantarflexion of the ankle joint. The result of this study were as follows: 1. In the gait cycle, The time parameters for the phases were showed significant difference without the terminal stance phase and terminal swing phase for the different walking speed. 2. The angle of ankle joint was no significant difference for each time point and MDF, MPF but increasing walking speed the angle had the increasing pattern slightly. 3. The angular velocity of ankle joint was showed the significant difference for LHC, RTO, RKC, LHU, MPF and MDF point along the walking speed. 4. TA was showed about 2-3 times muscle activity at the 1.75m/s than 1.25m/s in some phases. And it was showed the similar muscle activity between the 0.75m/s and 1.25m/s but, showed a little much muscle activity in the 0.75m/s. GM was showed about 2-3 times muscle activity in the 1.75m/s than 1.25m/s, and even much muscle activity at the 0.75m/s than 1.25m/s in some phases. GL was showed increasing pattern of muscle activity specially in the initial swing phase as the walking speed increased. SO was showed about 3 times muscle activity in the 1.75m/s than 1.25m/s during the plantarflexion of ankle joint. It was showed the similar muscle activity between the 0.75m/s and 1.25m/s but, showed a little much muscle activity in the 1.25m/s.

S. H. SHIN, T. W. KIM, M. S. KWON, S. G. GO, K. J. PARK. Analysis of the angular momentum on the lower extremity by change of starting block angles. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 165-175, 2004. The aim of this study is to show the effect of starting block angle on the starting motion of sprinters using a crouching start. After installing starting blocks on forced platform, and having four highly comparative sprinters use the starting blocks, I analyzed the angular momentum of a crouching start. From the results of the analysis, the following conclusions could be drawn: There were differences of angular momentum both in body's X, Y, and Z axes and in the thighs' X axes, but not in the pelvis and lower legs. As to the general change of block angle, we noticed that an angular momentum for each segments was higher at an angle of 50 to 55 degrees.

Diagnostic peritoneal lavage is a accurate and safe method confirming the intraabdominal injury with head trauma, unstable multiple injuried patients. But the development of imaging technique and the trend in noninvasive diagnostic value is decreasing now. In the emergency room, the emergency physicians are required the rapidity and accuracy in intial assessment and the decisions for the operation or not. So emergency physicians have been investigating the diagnostic method for intraabdomial injury that is more rapid, safe and accurate. Many diagnostic tools are developed and now accepted and used widely, among them the diagnostic peritoneal lavage is still the best method for unsatble or head injuried patients. But the positive diagnostic criterias are variable by many authors and still remain imperfectly. So our study was reviewed by medical record of patients who were undertaken the diagnostic peritoneal lavage for the diagnosis intraabdominal injury and statistical analysis was done compared with many criteria of red blood cell and white blood cell for the more accurate way. A retrospective study of diagnostic peritoneal lavage was done of 90 patients with blunt abdominal trauma during 2 years from January, 1996 to December, 1997 and summerized our experience. The results were as follows; 1) There are 73 males and 17 females in sex. The most common type of injury was the traffic accident. 2) With many variable criteria of RBC and WBC, the accuracy and the false positive and false negative were not different in statistical results. The average accurracy was 80.1%. 3) The operations were done in 30(33.3%) cases, and the most frequent injuried organ was the small bowel, 20 cases(66.7%).

Objectives : It is widely accepted that gonadal steroids are involved in organization and activation of sexual dimorphism in the brain areas related with spatial leaming. This study aimed to test the following hypothesis : 1) spatial memory is affected by sex, 2) this difference is related with brain differentiation by exposure to testosterone in the neonatal period, and/or 3) the sexual difference of spatial memory is the result of the interaction between organization of sexual dimorphism in the brain and the circulating testosterone after growing up. Methods : Testosterone enanthate 100 ㎍, ('androgenized') orvehicle ('control') was randomly administered to 28 female and 25 male rat pups within 24 hour of birth. The escape latencies (EL) in Morris water maze were measured in 15 and 16 week of age with vehicle ('baseline') and with 10 μmol/kg of testosterone ('with testosterone'), respectively. Each session Consis-ted of 10 trials, and means of the last 5 trials were analyzed. Results : The baseline EL of the males were significantly shorter than females regardless ofneonatal exposure to testosterone. With testosterone, EL of the androgenized females were significantly shorter than control females and comparable to those of males. Conclusion : Neonatal exposure to testosterone in female rats may develop a tesosterone-dependent male-like spatial leaming system.

The etiologies of alcohol dependence may be divided into three factors : biological, psychological, and social factors. Among these, many of the current articles deal with the genetic factors, due to rapid developments in methodology and so on. Because of these reasons, it is thought that it would be worthful to review the articles related to the genetic etiologies and other neurobio-logical etiologies of alcohol dependence at this point. Because alcohol dependence is a complicated and heterogenous disease, it is not likely to be associated with a single gene polymorphism. And as it is still early times in identifying its genetic etiology, think it is not easy to make conclusion in this field now. However, I believe that many recent studies using endophenotype and haplotype will give us more promising results. The fact that unlike other substances, alcohol dose not act on only one or two neurotransmitter receptors makes neurobio-logical research to be not easy one. It is interesting that some of the articles reported in this fields recently dose not confined to brain reward system but extended to CRF or molecular biology.

Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.
