Purpose: This study was done to develop an applicable training program for high school girls on sexual assertiveness. Method: The design combined methodological study and non-synchronized quasi experimental study designs. The participants were 174 high school girls from two schools. Two questionnaires were used, one consisted of 23 questions on self efficacy and the other, of 22 items on sexual assertiveness. The SPSS 10.0 program was used for data analysis. Experimental group 1(3 hour program) and experimental group 2(6 hour program) were received on sexual assertiveness. The sexual assertiveness program was carried out by members of the research team. There were no differences in demographic characteristics between control group, experimental group 1, and experimental group 2. Result: There was no significant increase in self efficacy scores in experimental group lover the control group, but there was a significant increase in sexual assertiveness scores in the experimental group lover the control group. There was an increase in self efficacy scores in experimental group 2 over the control group, but it was not significant. There was a significant increase in sexual assertiveness scores in experimental group 2 over the control group. There was no significant increase in self efficacy scores in the experimental group 2 over the experimental group 1, and there was no significant increase in sexual assertiveness scores in experimental group 2 over the experimental group I. Conclusion: The results show that a 3 hour program was as effective as a 6 hour program for sexual assertiveness. Therefore, it is advisable to use a hour program for clinical convenience. But further study is needed to determine the lasting effect on sexual assertiveness.

The purpose of this study was to evaluate the effect of the lateral displacement on the mandibular condylar growth in the rabbit. The experimental animals were twenty White NewZealand rabbits of 4-week old. Ten of them was used as control group, and experimental animal was composed of remaining ten. Laterodeviation appliance was made of cast base metal and appliance was cemented with resin in permanent fashion. Experimental group were sacrificed at 1, 2, 4, 6, 8 weeks form beginning of the experiment. Both of temporomandibular joint were prepared for histologic study. The conclusions are: 1. In control group, there was slight increase of proliferative zone and hypertrophic zone at 2-week control animal and slight reduction at 4-week. 6-week and 8-week control animal were similiar to 1-week control animal. 2. In right mandibular condyle of experimental group, 2-week experimental animal showed marked increase of proliferative zone and hypertrophic zone at posterior surface of condylar head. In 8-week experimental animal marked increase at anterior surface of anticular surface is observed. 3. In left mandibular condyle of experimental group, proliferative zone and hypertrophic zone were reduced at 1-week experimental animal and slight increase at 2-week. Proliferative zone and hypertrophic zone were reduced at 4-week experimental animal and were slightly increased at 6 week. 4. After 8 weeks, right and left condyle were not different in experimental group. The condylar cartilage was stabilized 8 weeks after the experiment. No marked traumatic change was seen, but minute focal bleeding was seen at articular cavity in 1-week, 2-week and 4-week experimental animal. 6-week and 8-week experimental animal did not show bleeding tendency in articular cavity.

The genetic variabilities of second chromosomes concealed Sasang natural and experimental populations of Drosophila melanogaster have been analyzed. The experimental population was composed of D. melanognter which had the lethal-free second chromosome collected from Sasang natural population in 1982. The results were as follow; The mean frequencies of deleterious genes were estimated % be 33.33% in Sasang natural population and 31.72% in experimental population. The allelism rates in lethal genes isolated from the natural and experimental populations were calculated to be about 0.95% and 12.28%, respectively. The allelism rates between lethal genes isolated from the natural population and those of the experimental population were calculated to be about 0.01%. The mean values of elimination by frequencies of deleterious genes and allelism rates were 0.0011 in the natural population and 0.0124 in the experimental population. The frequencies of phenotypic sterility of males in the natural and experimental populations were estimated to be 1.49% and 1.36%, respectively. The frequencies of genotypic sterility of females and males were estimated to be 0.90% and 1.80% in the natural population, and that of males was 2.38% in the experimental population.

It is very rare to conduct an experimental design with a single objective in mind. since we have uncertainties in model and its assumptions. Basically we have three approaches in literature to handle this problem, the mini-max, compound, constrained experimental design. Since Cook and Wong (1994) announced the equivalence between the compound and the constrained design, many constrained experimental design approaches have adopted the approximate design algorithm of compound experimental design. In this paper we attempt to modify the row-exchange algorithm under exact experimental design setting, not approximate experimental design one. This attempt will provide more realistic design setting for the field experiment. In this process we proposed another criterion on how to set the constrained experimental design. A graph to show the general issue of infeasibility, which occurs quite often in constrained experimental design, is suggested.

This study was investigated of the bone healing capacity by autologous fibrin glue in experimental bone defect dogs. The autologous fibrin glue manufactured just before the experiment was mixed with the concentrated fibrinogen from whole blood of the experimental dog and bovine thrombin. The experimental group was constituted with seven dogs. The experimental osteotomy was performed 5 mm length in bilateral region of proximal diaphyseal fibulae. The defected regions of experimental group were filled with the autologous fibrin glue by duploject. The experimental regions had been radiographed biweekly for 16 weeks to observe new bone formation and union. Bone alkaline phophatase (BALP) in all groups was evaluated biweekly till the end of the experiment to determine osteoblast activities. New bone formation had been observed in five regions of three dogs at four weeks after the experimental treatment and in two regions of one dog at ten weeks. The other seven regions of the experimental group and control group were not observed new bone formation until the end of the experiment. BALP value in four dogs observed new bone formation was increased to 97.10 IU/L (453.96%) at two weeks after the experimental treatment. The results of this experiment were suggested that the autologous fibrin glue was moderately effective in new bone formation in dogs.

PURPOSE: This study examined whether ankle joint stabilizing taping and muscle control taping influenced the ankle range of motion (ROM), muscle tone, and balance ability in chronic stroke patients. METHODS: Ten stroke patients were assigned randomly to experimental group 1 (joint stabilization taping n = 5) and experimental group 2 (Muscle control taping n = 5). After general physical therapy in both groups, ankle stabilization taping was applied to experimental group 1, and muscle control taping was applied to experimental group 2 three times a week for a total of six weeks (18 times). RESULTS: The muscle tone and stiffness of the gastrocnemius (GCM) showed significant differences between the experimental 1 and experimental 2 groups (p < .05). The Berg Balance Scale (BBS) and ROM also showed significant differences within the experimental 1 and experimental 2 groups (p < .05). The BBS and ROM also showed no significant differences between the experimental 1 and experimental 2 groups (p > .05). CONCLUSION: This study examined the muscle tone, balance, and ROM on the paraplegic side of stroke patients using kinesio taping, and the effect of the taping application method was confirmed from the preceding study. Therefore, it can decrease the paralysis side muscle tone and improve the ROM and balance ability.

The purpose of this study was to analyze the effects of storytelling and discussion types on the language development of young children. 32 treatment sessions were applied to the two experimental groups and the control group(N=151) during 16 weeks. One experimental group children discussed among themselves while the other experimental group children did with teacher. The control group children listened to storytelling by their teacher. Findings are as followings. Children of two experimental groups discussing on storytelling gained higher scores in vocabulary test and reading test than those of control group. The first experimental group discussing about storytelling with teacher gained higher scores in comprehension test than the second experimental group debating among themselves. But, there was no statistically significant difference on vocabulary and reading tests between two experimental groups. It was statistically significant difference on meaning test between two experimental groups.

Up to now. vibration analysis and vibration engineering have been developed, encompassing the aspects of both experimental and analytical techniques. Using experimental modal analysis or modal testing, the mode shapes and frequencies of practical structure can be measured accurately. Curve-Fitting Method is realized through experimental modal identification. In the experimental modal parameter estimation, the estimation of modal damping factor is difficult for complicated and large structure. Also numbers of Selected mode are determined before the procedure. This paper describes the vibration shape of the super-structure model of ship through experimental modal analysis.
