Purpose: The purpose of this study is to assess the relationship between the time spent designing custom abutments and repeated learning using dental implant computer aided design (CAD) software. Materials and Methods: The design of customized abutments was performed four stages using the 3DS CAD software and the EXO CAD software, and measured repeatedly three times by each stage. Learning effect by repetition was presented with the learning curve, and the significance of the reduction in the total time and the time at each stage spent on designing was evaluated using the Friedman test and the Wilcoxon signed rank test. The difference in the design time between groups was analyzed using the repeated measure two-way ANOVA. Statistical analysis was performed using the SPSS statistics software (P < 0.05). Results: Repeated learning of the customized abutment design displayed a significant difference according to the number of repetition and the stage (P < 0.001). The difference in the time spent designing was found to be significant (P < 0.001), and that between the CAD software programs was also significant (P = 0.006). Conclusion: Repeated learning of CAD software shortened the time spent designing. While less design time on average was spent with the 3DS CAD than with the EXO CAD, the EXO CAD showed better results in terms of learning rate according to learning effect.

The purpose of this study was to identify the effects of upper and lower limb coordinated exercise for gait ability in stroke patients. Upper and lower limb coordinated exercise method was conducted in two different groups; one is an one leg support group and the other is a non support group. In this study, 14 patients were participated. One leg support group was applied to 7 patients, and non support group was applied to 7 patients. Both group carried out 3 times a week for 30 minutes during 4 weeks. Data were analyzed statistically via Repeated two-way ANOVA, Mann-Whitney U test, and Friedman test. The results of the measurement analysis were summarized as follows: 1. There were significant differences in 10MWT among 2 groups after intervention(p<.05). 2. There were significant differences in F8WT, FSST among 2 groups after intervention(p<.05). According to Bonferroni test, one leg support group had significant increased from pre-intervention to post-4 week. However, there were no significant differences in nonsupport group. In conclusion, improvement of gait ability in chronic stroke patients was effect to upper and lower limb coordinated exercise.

Purpose: This study was conducted to examine the effect of kinesio taping (KT) on vertical jumping performance. Methods: Young women (n=24) performed vertical jumping under three conditions: kinesio taping, placebo taping, and no taping. All tapes were applied to both quadriceps and the gastrocnemius of the subjects. Vertical jump height and power were measured using an OptoGait, and the non-parametric Friedman test was used to identify differences between conditions. Results: No significant differences in maximum jump height or peak jump power between were observed between taping conditions. Conclusion: The results showed that KT did not facilitate muscle performance by generating higher jumping power or yielding a better jumping performance. As the functional performance is related to muscle strength, this finding may be explained by the fact that KT has no effects on muscle strength.

The cost-effective reduction of occupational radiation exposure (ORE) dose at a nuclear power plant could not be achieved without going through an extensive analysis of accumulated ORE dose data of existing plants. It is necessary to identify what are high ORE jobs for ALARA implementation. In this study, the Rank Sum Method (RSM) is used in identifying high ORE jobs. As a case study, the database of ORE-related maintenance and repair jobs for Kori Units 3 and 4 is used for assessment, and top twenty high ORE jobs are identified. The results are also verified and validated using the Friedman test, and RSM is found to be a very efficient way of analyzing the data.

Purpose: This study was conducted to assess needs at each end-of-life care stage and to analyze importance and difficulty of care needs for home care nursing among non-cancer patients. Methods: We used a retrospective design. Total eligible patients were 117 at the ages of 40 and over, who continuously received home care nursing throughout beginning, stable, and near death stages, and finally died at home from January 1, 2006 to December 31, 2006. Descriptive statistics, Cochran's Q test, Friedman's test were used for data analysis. Results: In the area of physical care, the care need for 'assistance for activities in daily life' was significantly highest in the beginning stage. The care need for 'aggravation or adverse changes in physical symptoms' was significantly increased in the near death stage. In the area of psychospiritual care, 'family's psychological burden' was revealed as having the highest rate of care needs in the every stage. Conclusion: Future intervention should consider assessing care needs in end-of-life care for non-cancer patients who are provided with home care nursing.

Purpose: This study was conducted to exam the effects of the Abbreviated Cognitive Behavioral Therapy(ACBT) on chronic insomnia. Methods: Study was one-group interrupted time series study that involved 13 adults(mean age=51.7, aged 25-77 years) with chronic primary insomnia who visited sleep disorder clinic of S Hospital from November 2004 to October 2005. The subjects received 2-session individual ACBT with 2 week-interval($1^{st}$: 1.5- 2hrs, $2^{nd}$: 20-30min). To measure the subjective insomnia severity and sleep patterns, 3 times of insomnia severity index and sleep logs were completed(before ACBT, after ACBT, and 3-month after ACBT). The main outcomes were subjective insomnia severity and sleep patterns(sleep onset latency, waking after sleep onset, and total sleep time, sleep efficiency). The data were analyzed with SPSS 10.0 version program by Friedman test, Wilcoxon signed rank test with Bonferroni correction. Results: There were statistically significant decrease in insomnia severity index, sleep onset latency, and waking after sleep onset, and increase total sleep time and sleep efficiency. Conclusion: ACBT was effective in reducing subjective insomnia severity and improving sleep patterns. Sleep improvement was better sustained over time with ACBT.

Objective: The purpose of this retrospective study was to investigate short-term and long-term skeletodental outcomes of Class III activator treatment. Methods: A Class III activator treatment group (AG) comprised of 22 patients (9 boys, 13 girls) was compared with a Class III control group (CG) comprised of 17 patients (6 boys, 11 girls). The total treatment period was divided into three stages; the initial stage (T1), the post-activator treatment or post-mandibular growth peak stage (T2), and the long-term follow-up stage (T3). Cephalometric changes were evaluated statistically via the Mann-Whitney U-test and the Friedman test. Results: The AG exhibited significant increases in the SNA angle, ANB angle, Wits appraisal, A point-N perpendicular, Convexity of A point, and proclination of the maxillary incisors, from T1 to T2. In the long-term follow-up (T1-T3), the AG exhibited significantly greater increases in the ANB angle, Wits appraisal, and Convexity of A point than the CG. Conclusions: Favorable skeletal outcomes induced during the Class III activator treatment period were generally maintained until the long-term follow-up period of the post-mandibular growth peak stage.

Purpose: 본 연구는 단하지 보조기를 사용하는 뇌졸중환자의 시-거리 보행변수에 대한 청각신호 효과에 대한 알아보고자 하는 것이다. Methods: 9명의 뇌졸중환자가 본 연구에 참여하였으며 대상자는 보조기 착용이 없는 경우, 기존 보조기 착용의 경우 그리고 청각신호 보조기 착용의 경우에 각각 시-거리 보행 변수에 대해 측정하였다. 8대의 동작분석 카메라 시스템(Motion Analysis Corporation, Santa Rosa, USA)을 사용하여 시-거리 보행 변수를 측정하였으며 Wilcoxon rank sum test을 이용하여 양하지의 대칭성을 분석하였고 Friedman test를 사용하여 다른 보조기 사용에 따른 효과를 알아보았다. Results: 청각 신호 보조기의 경우, 손상측과 비손상측의 보행속도, 활보장 그리고 분속수가 대칭적으로 되었다. 손상측의 경우, 단하지 보조기를 착용하였을 때가 착용하지 않았을 때보다 대체적으로 보행 변수들이 증가하였다. 청각 신호 단하지 보조기를 착용하였을 때 손상측 하지의 보행 속도, 활보장, 보장, 양하지 지지 시간이 증가하였고 단하지 지지 시간은 감소하였다. Conclusion: 청각 신호 단하지 보조기 착용 시 보행 속도, 활보장, 보장은 보조기를 착용하지 않았을 때보다는 증가하였으나 청각 신호 단하지 보조기와 기존 단하지 보조기 착용 사이에는 차이가 없었다. 하지만, 본 연구의 결과는 청각 신호 단하지 보조기가 뇌졸중 환자의 시-거리 보행 변수를 개선할 수 있음을 보여주었고 앞으로 다양한 보행 변수들에 대한 연구가 필요하다고 생각한다.

Purpose: The purpose of this study was to develop a suicide prevention nursing competency program for visiting nurses, and to examine the effect of this program on suicide prevention-related knowledge, attitudes, and behaviors. Methods: A total of 66 visiting nurses were recruited from 10 public health centers and divided equally into the experimental and control group. For the experimental group, the suicide prevention nursing competency program was provided twice a week for 120 minutes across 3 weeks. Participants were asked questions related to suicide prevention knowledge, attitudes, and behaviors at pre, post, and 1 month after the intervention. Data were analyzed using descriptive statistics, a t-test, repeated measure ANOVA, and Friedman test. Results: There were significant differences in knowledge and behaviors at the measured time periods, and significant differences in attitudes and behaviors between the two groups. There were also significant interactions between groups and times in attitudes and behaviors. These results suggest that the effects of the program were persistent until the 1-month follow-up. Conclusion: The developed suicide prevention nursing competency program is effective in evidence-based education for visiting nurses to increase suicide prevention-related knowledge, attitudes, and behaviors.
