  • Inference on the present data will be more reliable when the data arising from previous similar studies are available. The data arising from previous studies are referred as historical data. The power prior is defined by the likelihood function based on the historical data to the power $a_0$, where $0\;{\le}\;a_0\;{\le}\;1$. The power prior is a useful informative prior for Bayesian inference such as model selection and model comparison. We utilize the historical data to perform multiple comparison in the one-way ANOVA model. We demonstrate our results with some simulated datasets under a simple order restriction between the treatments.

  • The purpose of this study was to analyze group differences of Commitment to career choice and Career stress coping strategy by the Career decision and Career preparation behavior for College Students. Through the results of this study we wanted to look for discriminatory implications for the counseling intervention. The data of 720 college students were collected for the study. The distinction of four types was revealed by the results from Crosstabs and One-way ANOVA. The frequency of upper grades indicated ideal type. But the immature type was fourth grade. There were significant differences in accordance with the two-dimensional typology of Commitment to career choice and Career stress coping strategy by One-way ANOVA. Discussion focused on effective intervention strategies in career counseling based on group differences by the Career decision and Career Preparation Behavior.

  • 국내 온라인 게임은 1996년 바람의 나라를 시작과 1998년 리니지의 성공으로 2020년 오늘날에 이르러 온라인 게임은 국내 게임산업의 중추 플랫폼으로 발전해 왔다. 1999년말부터 2000년대 초반에는 온라인 게임의 태동 시기로 온라인 게임의 수요보다 공급이 부족하였지만 20년이 지난 오늘날에는 많은 수의 온라인 게임들이 시장에 나오고 있어 광고, 이벤트 등 마케팅 활동이 중요한 시기가 되었다. 이에 게임 출시 시기에 따라 이벤트의 중요성이 게임의 성공 여부에 커다란 영향을 미칠 것으로 예상하고, 본 연구에서는 출시 시기에 따라 세 개의 게임을 선정하여 One-way ANOVA을 실시하여 세 게임간의 이벤트의 평균의 차이를 연구하였다.

  • The purpose of this study was to analyze a change of maximal grip forces and EMG of agonists in upper extremity of 8 professional Ssirum players according to Satbar-grip patterns, to elucidate prime agonist muscles, contribution rate of each muscle, and a difference on EMG in upper extremity. one-way ANOVA(RM) performed for average and maximal values of each player after standardization and statistical significance was set as p<.05. The result includes the following: the highest grip force was A type with a statistic significance using one-way ANOVA and Duncan's comparison between A and C type. In summary the highest grip force was exerted on extension in the wrist than flexion in all grip types. Average and maximal values of biceps brachii and brachioradialis muscles were statistically significant and ones of flexor carpi ulnaris and extensor capi ulnaris were not.

  • Purpose: This study provided the basic data for selecting the zirconia blocks by comparing the mechanical properties of the all ceramic crown between the domestic, import, translucent and shade blocks that were used in clinically. Methods: Currently, the most commercial block of five types(one import and two domestic block which is the translucent and shade) were used. It were elucidated by means of three point bending test, hardness test, FE-SEM observations and EDX analysis. The results were analyzed using a one-way ANOVA and Scheffe post hoc test for significant findings. Results: For flexural strength, LT specimen was the highest as 733.1 MPa, followed by JT specimen(712.0 MPa), ZT specimen(646.0 MPa), LS specimen(553.1 MPa), JS specimen(429.0 MPa). One-way ANOVA showed statistically significant difference between groups for flexural strength(p<0.05). For hardness, ZT specimen was the highest as 1556.5 Hv, followed by JT specimen(1540.3 Hv), LT specimen(1512.3 Hv), JS specimen(1472.0 Hv), LS specimen(1353.3 Hv). One-way ANOVA showed statistically significant difference between groups for hardness(p<0.05). Conclusion: Domestic block was higher than import block for flexural strength, and translucent block was higher than shade block for flexural strength. However, all blocks showed clinically acceptable range. There was no significant difference in hardness between domestic and import blocks. And significant difference was observed in translucent and shade blocks.

  • The purpose of this study was to investigate the nursing behavior and delegation status of nursing hospital nurses and to provide basic data for improving the quality of medical services. The subjects of this study were data collected from July 26 to December 23, 2013, for 140 nurses with more than 3 years of experience in nursing hospitals. Collected data were analyzed by frequency analysis, mean and standard deviation, independent t-test and One way ANOVA of SPSS 20.0 statistical program. Collected data were analyzed by frequency analysis, mean and standard deviation, independent t-test and one way ANOVA of SPSS 20.0 statistical program.. As a result of this study, the case of delegation of nursing behavior was higher in case of no protocol of nursing delegation procedure than in case of having protocol. This study suggests that nursing practice of nursing hospital nurses can be a major factor in declining the quality of medical services in the absence of specified standards or procedures for delegation. Procedures, methods and guidelines are required.

  • The government is trying to secure reliability by raising the accuracy, objectivity, and transparency of the official price by promoting the reliability improvement plan of the official price and increasing the realization rate, but the Realization rate of Publicly Notified Individual Land Price is showing a big difference because the current market price is not fully reflected in the official price. Therefore, this study collected the actual transaction price reported to the RTMS in Wansan-gu, Jeonju, Jeollabuk-do and the individual official price of the KRAS and calculated the realization rate of publicly notified individual Land Price. SPSS 25.0 program was used for the empirical analysis of this study. The Dependent Variable was the realization rate of publicly notified individual Land Price, and Independent Variables, was six land characteristics items were selected, one-way ANOVA was conducted and post-test was conducted by Scheffe method. As a result of the analysis, average difference in realization rate of publicly notified individual Land Price was found in Residential areas, Commercial areas, and Farmland, Public land and Residential and commercia, Residential and Forest. Especially, it was found that the price of commercial area is higher than that of residential area and green area, and the price is less reflected in individual official land price.
