The purpose of this study was to investigate effect of psychotic patient after applying anger management video and tea gathering program to psychotic patient. This study was an experimental research and used nonequivalent control-group pretest-posttest design. Study subjects were 16 patients for an experimental group and 16 for a control group-32 in total- who were psychotic patients hospitalized in a closed ward in H mental hospital. The measurement variable is an aggressiveness scale, and the effect of the program was measured once after the video program and once after eight tea gathering. Data Analysis methods were real number and percentage, average and standard deviation, χ² test, t-test, paired t-test, and Repeated measure ANOVA. The aggression of an experiment group was significantly lower than the control group(F=14.38, p< .001). Aggressive sub-item, hostility (F=8.53, p< .001), anger (F=6.10, p=.004), verbal aggression(F=7.58, p< .001), physical aggression(F=13.92, p< .001) all of tte experiment group was significantly lower than control group. Based on these results, anger management programs can be used as basic data for anger control in psychotic patient or in various groups.

The purpose of this study was to identify the effect of structured patient education on knowledge of Hepatitis B type and behavior about self care in chronic hepatitis B patients, and to fine the strategy to promote their self care behavior. The research design was quasi-experiment research. The study method had been done by investigating the experimental group and control group through the questionnaire on 50 patients who had been out patient medicine department in U university hospital in Ulsan from september 1st 1997 to the end of October, 1997. The analysis of the collected material had been done for the homogeneity test in which general characterics of experimental group and control group had been tested by $x^2-test$ and the homogeneity test of the knowledge of hepatitis B type and self care behavior before by t-test. To test the hypothesis the t-test had been given for the difference of the knowledge of hepatitis B type and self care behavior between the two groups and the correlation between knowledge of hepatitis B type and self care behavior performance had been tested by Pearson's correlation coefficient. The results as follows : 1. The 1st hypothesis 'The experimental group which received the structured education should be higher in the knowledge of hepatitis B type than the control group' was supported(t=-6.25, P=.000). 2. The 2nd hypothesis 'The experimental group which received the structured education whould be higher in the self care behavior performance than the control group' was supported(t=-5.15, P=.000). 3. The 3rd hypothesis 'The higher the knowledge of hepatitis B type in the patient the higher the self care behavior performance degree' was supported(r=.492, P=.001). In conclusion, the patients who received the structured education showed the increase in the degree of knowledge of hepatitis B type and self care behavior performance. so the structured education had been judged the nursing intervention had been prerequisite in increasing knowledge of hepatitis B type and self care behavior performance of the chronic hepatitis B patients.

This study quantitatively evaluated size selectivity for three netting shapes (T0; regular, T45, T90) and hanging ratio (35%, 70%) of T0 netting used for trawl codend. The size selectivity experiment was performed in a tank using a cube experimental model with a length of 50 cm on one side and 389 experimental individuals, jack mackerel (Trachurus japonicus). In the selectivity analysis, a selectivity curve was created based on the selection ratio using a logistic function, and the 25%, 50%, and 70% selection length and selection range (SR) were obtained. The T0 netting was 19.54 cm when the 50% selective length, which is a selectivity evaluation index, had a hanging ratio of 35%, a selection range of 0.51 cm, and 22.70 cm and 3.08 cm for the hanging ratio of 70%. The T45 netting was 24.34 cm and 2.13 cm, and the T90 netting was 23.51 cm and 2.84 cm. The results of the T45 netting and the T90 netting are similar, and the 50% selection length and selection range were relatively larger than the T0 netting. There was a significant difference in the correlation between the circumference of the inner circle of the mesh by the shape of the netting and the body girth of the experimental individual (Pearson test, r = 0.86, p < 0.05). There was no significant difference in the correlation between the selection ratio by the T0 netting, T45 netting, and T90 netting with a 70% hanging ratio (one-way ANOVA, p > 0.05). The results of this study showed that selectivity such as T45 netting and T90 netting appeared when the hanging ratio, which maximizes the area of T0 netting, was maintained at 70%.

This study was carried out to investigate what kinds of statistical techniques have been used to analyze data from oriental medicine research, For study, 551 original articles which used statistical techniques in their data analysis were selected form the articles published in The journal of Korean Acupuncture & Moxibustion Society(JKAMS) between 1984 to 2002. among them, 122 articles used descriptive statistics while 429 articles used inferential statistics for data analysis. For that 429 articles, t-test (189 articles), analysis fo variance (111 articles), chi-square test (14 articles), correlation (10 articles), regression analysis (4 articles), factor analysis(5 articles), or nonparametric test (23 articles) were chose to analyze the data. Nonparametric approach has substantial power in case data do not meet the assumption of normality. This method is not only easy to use ut also provides measures of the statistical variation of nominal and ordinal scale. This study shows that more and more recent papers use nonparametric test compared to the old articles. nine different statistical software or packages (SAS, SPSS, Statview, Minitab, Sigma plot, ISP, Graphpad prism, Excel, Access) have been used in the articles published JKMAS. High level statistical techniques such as SAS, SPSS, and Statview are user friendly and used most for acupuncture and Moxibustion research. Including tables and plots in an article facilitates understanding family process data from a descriptive standpoint, minimized erroneous statistical conclusions, and clarifies theoretically important relationships among variables. Table and plots have been used 500 and 233 articles, respectively. A computer procedure is proposed and illustrated with statistical packages using SAS, SPSS, Statview and ISP.

PURPOSE. The purpose of this study was to compare the performance of Accura to that of the T-scan for indicating occlusal contacts. MATERIALS AND METHODS. Twenty-four subjects were selected. Their maxillary dental casts were scanned with a model scanner. The Stereolithography files of the casts were positioned to align with the occlusal plane. Occlusal surfaces of every tooth were divided into three to six anatomic regions. T-scan and Accura recordings were made during two masticatory cycles. The T-scan and Accura images were captured at the maximum bite force and overlapped to the cast. Photographs of interocclusal records were used as the reference during overlap. The occlusal contacts were counted to compare the T-scan and Accura. McNemar's test was used for statistical significance and the corresponding P-values were calculated from a chi-square distribution with one degree of freedom. The accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of Accura were calculated relative to the T-scan values as a control. RESULTS. No statistical differences (P>.05) were found between the T-scan and Accura methods. The accuracy of Accura was 75.8%, sensitivity was 82.1%, specificity was 60.1%, PPV was 82.9%, and NPV was 60.1%. CONCLUSION. Accura could be another possible option as a computerized occlusal analysis system for indicating occlusal contacts at maximum intercuspation.

Purpose: This study purposed to examine the effect on health educational curriculum by grasping knowledge, attitude, and the extent of practicing it after giving a health education curriculum for 17 hours. Methods: This study was a non-equivalent control group pretest-posttest conducted with the first-graders enrolled in a middle school students in Gyeonggi Province. A total of 191 completed questionnaires from the test group and the control group each were used for the final analysis. The survey period was from March 5 to March 13, 2009 before the education was given from July 20 to July 25, 2009 after the education. A total of 38 questions were used to measure knowledge and a total of 39 questions were used to measure attitude and practice. This study used $x^2$ test, ANOVA, and t-test, Paired t-test. Results: After the health education curriculum was given, the test group s knowledge of health education was found higher than that of the control group. There was a difference between two groups, but considering the perfect score of 38, the knowledge scores of both groups were not high. With regard to each group s attitude and practice of health education, the study compared the scores obtained before and after the education and found that the test group had higher scores than the control group, showing a significant difference. Conclusion: In order for a health education curriculum to successfully have favorable influence on the health of teenagers, the curriculum should be offered for a more extended period of time than 17 hours and as a compulsory course, not a selective one, so that all the students can develop their health management capabilities.

Purpose: The purpose of this study was to prove the effects of the PNF patterns combined with whole-body vibration (PWBV) training on muscle strength, balance, walking speed, and endurance in stroke patients. Methods: Sixteen subjects were randomly assigned to the PWBV group (n=8) and the whole-body vibration (WBV) group (n=8). The PWBV group performed PNF pattern exercises using sprinter combined with WBV, while the WBV group performed using squatting for 30 minutes. Both groups performed therapeutic interventions five days per week over a period of four weeks. The manual muscle test, timed up and go test (TUG), 10-meter walk test (10MWT), and six-minute walk test (6MWT) were used to assess the muscle strength, balance, and gait of the participants. The SPSS Ver. 19.0 statistical program was used for data processing. Statistical analysis included a pared t-test to compare the pre- and post-intervention, and an independent t-test was used to compare groups. The significance level was set as 0.05. Results: The PWBV group and WBV group showed significant improvements in the TUG, 10MWT, and 6MWT (P<0.05). Significant differences between the PWBV and WBV groups were found (P<0.05). Conclusion: The PWBV improved muscle strength, balance, gait speed, and endurance in stroke patients. Thus, PWBV may be suggested as a therapeutic intervention in patients with stroke hemiplegia.

Purpose: A cost effective tool for the clinical measurement of trunk reposition sense is clearly needed. This study was to analyze intrarater and interrater Reliability of trunk repositioning error (TRE) test which assesses trunk position sense using a portable digital inclinometer. Methods: Twenty four normal healthy subjects were recruited. TRE was measured using a portable digital inclinometer. A digital inclinometer (Acumar-ACU360; Lafayetter Instrument) with precision to $1^{\circ}$ was placed on skin over the spinous process from first to second thoracic vertebra (T1-T2) and secured with double-sided tape. TRE test during sitting forward and lateral flexion movement was assessed. When they reached a point approximately 50% of full trunk flexion range, the examiner instructed the subjects to stop and told them. This was the target position that they should try to reproduce exactly. Each subject performed six trials. Results: ICC (2,1) for intrarater reliability (with-day and between-day) of TRE test in sagittal and frontal plane of movement was 0.75 and 0.78 (excellent reliability). Interrater reliability was 0.66 in sagittal and 0.64, frontal plane (fair to good reliability). However, there were poor correlations between an average of TRE test in sagittal and frontal plane. Conclusion: TRE test using a portable digital inclinometer demonstrated good to excellent reliability. The device may be a cost effective clinical measurement for trunk reposition sense measurement.
