The purpose of this study was to verify the effectiveness of sociodrama on adolescents who are maladjusted in school. For this study, nine adolescents were selected from a middle school located in Seoul. The Inventory of School adjustment by Bae Sook-Jin, Buss-Durkee Hostility Inventory(BDHI) and Impulsivity Test by Eysenck were administered. The experiment group acted out a sociodrama twelve times. The first follow-up test was conducted twelve weeks after the pre-test. The second follow-up test was conducted six weeks after first follow-up test. Each time the adolescents acted out a sociodrama their behavior was recorded by a video- camera and then documented by research assistants. Also in order to discover any changes in daily life after sociodrama, an interview survey were done with the adolescents' teachers. The findings were as follows. First, in the initial follow-up test degree of school-maladjustment was less than in the pre-test. Further decreases in the level of maladjustment were noted in the subsequent follow-ups. Therefore, it can be concluded that the performance of sociodramas can reduce school-maladjustment among adolescents and that this reduced level is maintained. Second, the level of hostility discovered in the first follow-up test was less than that in the pre-test, and this level continued to decrease in the following follow-ups. Therefore, we may conclude that sociodrama that reduces adolescent hostility and the reduced levels continue. Finally, the degree of impulse detected in the first follow-up was, once again, less than that of the pre-test, And, as in the other cases, there was a continued decrease in this level. We may therefore conclude that sociodrama does reduce the impulse of adolescents and that this reduction is maintained. This study indicates that sociodrama is an effective method to improve the psychological characters of adolescents who are maladjusted in school. Given the above, a follow up study is suggested.

By measuring changes in blood lactate and plasma enzyme (CPK, GOT, GPT) with electrical stimulation applied at two duty cycles, this study is intended to look into which type of duty cycle may have more effects on blood lactate and plasma enzyme constituents through animal experiment so as to determine any duty cycle appropriate for electrical treatment. In this study, electrical stimulation was applied to total 20 Korean house rabbits (weight: 3~3.5 kg) by means of an electrical therapeutic apparatus called TS6000 (made in Netherlands) at duty cycle of 50% and 20% respectively for 30 minutes. Here, 5 cc of blood was collected from their carotid artery before stimulation and in 30 minutes after stimulation respectively to carry out biochemical experiment and analysis. As determined through the above experiment, blood lactate rate was increased to 333.07% at 50% duty cycle after experiment and 185.71% at 20% duty cycle after experiment respectively. In both cases, blood lactate rate was significantly increased to higher level after electrical stimulation than before. Moreover, the rate of change in the average of blood lactate rate at both duty cycles also showed significant differences. CPK rate was boosted to 301.82% at 50% duty cycle after experiment and 321.35% at 20% duty cycle after experiment respectively. In both cases, CPK rate was remarkably boosted to higher level after stimulation than before (p<.05). However, there was not any significant difference in the rate of change in average CPK at both duty cycles (p<.05). GOT rate was significantly boosted up to 38.97% at 50% duty cycle after experiment (p<.05), while it was slightly increased to 1.68% at 20% duty cycle after experiment without any significant difference. Rather, GPT rate dropped slightly at both duty cycles after experiment, but there was not any significant difference. Although blood lactate and GOT were relatively less generated at 20% duty cycle after electrical stimulation than at 50% duty cycle, the change of duty cycle didn't have any significant influence on CPK rate. In this regard, this study failed to come any consistent conclusion about the association between change of duty cycle and muscle fatigue. Therefore, it is advisable that follow-up studies seek various ways to a little more effectively apply electrical stimulation to laboratory animals by avoiding their muscle fatigue.

Objective: Physical therapy techniques are required for patients with temporomandibular joint disorder (TMD), but the effects of treatment have not been compared. Therefore, effects of transcutaneous electrical nerve stimulation (TENS) and low level laser (LLL), which are most commonly used interventions, were compared. Design: Randomized controlled trial. Methods: Thirty-six participants with pain in the temporomandibular joint were enrolled, and 12 participants were randomly assigned to either the TENS group, LLL group, or placebo group. Each intervention was performed for a total of 6 sessions for 2 weeks. For the evaluation of the participants, the mouth opening (MO), pressure pain threshold (PPT), and stress were measured at three time periods: baseline, post-test, and follow-up at 2 weeks. Results: Significant interaction between groups according to each evaluation point was found only in PPT-masseter (p<0.05). The evaluation time point at which a significant difference appeared was at the post-test and follow-up at 2 weeks time periods. As a result of the post-test, the LLL group showed a significant improvement compared to the TENS group (p<0.05), and at 2 weeks follow-up, the TENS group showed a significant improvement compared to the placebo group (p<0.05). Conclusions: In this study, an experiment was conducted to compare the treatment effects when TENS, LLL, and placebo were given to patients with TMD. In addition, by quantitatively presenting the effect size of each treatment, this study suggests clinical use of TENS and LLL treatment for TMD.

Oral medication is the most frequent treatment measure for follow up treatment, which is leading by childrens' parents for them. In medication for preoperational children, they tend to concentrate the result rather than the motivation or cause. So, they frequently refuse medication which has bitter taste. So this study was attempted to develop token economy program which promote children's medication and help their parents, and to evaluate its' effect to construct the experimental ground. This study was a quasi experimental study under the nonequivalent control group posttest only design. The subjects of this study were 36 children who were aged 3-6 years and admitted pediatric ward because of their respiratory disease. Token economy program was consisted of cartoon record paper with stickers which expresses the better medication is taken the more germs die, and gift was given for back up reinforcer. To evaluate this program, time for oral medication was measured to both experimental group and control group. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with t-test. The results of this study were as follows: 1. Between experimental group and control group, there was no significant difference (t=-1.2411, P=0.2374). Therefore, the hypothesis of this study was rejected. In conclusion, the token economy program for follow up care didn't change the children's behavior of oral medication. But it was found that the cartoon on recording paper gave a pleasure to participated children. Parents who were in experimental group expressed their appreciation for token economy program. So it can be said that the token economy program for follow up care was effective in inducing the children's pleasure and parents' satisfaction even though it wasn't successful in experiment. If the measuring tools for token economy program was made with well planned design and high reliability, it can be improved the effectiveness of that To develope the theoretical bases of nursing care, the well planned programs and measuring tools for them should be developed.

With increasing recognition on conservation of endangered species in Taiwan, one of the major conservation projects is the habitat restoration of Formosan Landlocked Salmon which is major threatened by check dams in the channel for their blockading pathway to upstream and causing the problems of population isolation and close-blood mating. By creating an opening in the central dam body appropriately, partial removal dams can provide pathway for the fish for the better upstream channel habitat. Four check dams at Gau-Shan Creek were remodeled between April of 1999 and September of 2002 with information supported from model experiments under certain hydraulic condition of field environment. Based on the follow-up investigation, the channel morphology of observation sections is in stable condition and the total number of Formosan Landlocked Salmon in this creek increased promptly at the reach containing partial-removed dams.
