  • In this paper, a new test criterion for binary decision problems is proposed. The integrated power flunction over a parameter interval is first itroduced as an extension of the power function. The concept of the most integrated powerful (MIP) test based on the integrated power function is then introduced. The MIP criterion is to masimize the value of the integrated power function in any paricular parameter interval. As an applicationof the MIP test, the known signal detection problem is considered. The test statistic of the MIP detector for known signals is obtained and an approximation to the MIP test statistic is also considered.

  • This present study proposed a newly developed test method to evaluate the dexterity and mobility of a firefighter's protective gloves. The first step evaluated the mobility and dexterity of the current type of fire protective gloves and three new types of protective gloves using Don-doff test, ASTM dexterity, Minnesota dexterity, Bennett hand tool test, and ASTM torque test. Three firefighters ($47.3{\pm}5.0yr$ in age, $178.6{\pm}2.9cm$ in height) participated in a series of experiments. The second step was to design and suggest an integrated test method based on the results of the first experiment. As a result of the first experiment, we concluded that 1) the mobility and dexterity tests for firefighting gloves should include both wet and dry tests, 2) The three kinds of dexterity tests could be integrated into one test, and 3) The don-doff test and the torque test should be independent from the newly developed integrated test. In summary, we suggested a simplified test method that combined ASTM dexterity, Minnesota dexterity, and Bennett hand tool test. The integrated system can reduce total time spent on dexterity tests and improve the validity of the test in terms of firefighters' manual work.

  • The role of the integrated development environment is very important in software development of a development project. After many developers develop different modules, software product is completed through compile, debugging, integration, testing, and distribution. However, bugs and various issues in the development process cause problems such as quality deterioration of software product and dissatisfaction with requirements. So the need for automated testing to avoid these problems and improve quality has increased. In this study, we propose test automation modules of four perspectives to improve quality throughout the test automation in an integrated development environment. Each automation module operates through the tool chain of an integrated build framework implemented on the devops.

  • This study investigated the effectiveness of traffic safety education by integrated activities on children's traffic safety knowledge. Subjects were 55 kindergarten children aged 5 years old. The subjects were divided into experimental and control groups. Traffic safety education by integrated activities were applied in the experimental group for 6 weeks. The traffic safety knowledge test was administered to the experimental and control groups for pre-test and post-test analyses. ANCOVA was carried out for both groups to verify the hypothesis of this study. There were statistically significant differences of the children's traffic safety knowledge score including walking, bike, and automobile between the experimental and control groups. To conclude, traffic safety education by integrated activities was very effective to increase children's traffic safety knowledge.

  • The purpose of this study is to identify the effects of a group integrated intervention program that simultaneously conducts cognitive activities, physical activities, emotional activities and social interactions by integrating animal-assisted therapy (AAT) and integrated elderly play therapy based on the cognitive functions and depression of the elderly who live alone. This study follows a pre-test post-test design with a nonequivalent control group, to verify the effectiveness of a group integrated intervention. It applies a group integrated intervention program to 20 elderly people who live alone, aged 65 and above (10 in the experimental group, 10 in the control group), once a week for 90 minutes across eight weeks. The study went through MMSE-K, TMT-A and GDSSF-A to assess cognitive functions and the level of depression. The group integrated intervention increased the cognitive functions of the experimental group and decreased levels of depression. Therefore, this study verified that a group integrated intervention program of AAT and integrated play therapy of the elderly, is an effective for increasing cognitive functions and decreasing depression levels of the elderly who live alone. Based on these findings, the study suggests that there is a need to continuously expand group integrated intervention programs and provide relevant political support.

  • This paper is to present linkage parameter to integrate statistical models and physical models for accelerated life test. Statistical models represent the relationship of probability distribution and life. Physical models show the relationship of life and stress. Moreover, this study proposes the four steps for construction of integrated models for accelerated life test using linkage parameter. Finally, this paper develops new integrated models such as extreme value distribution-general Eyring, linearly increasing failure rate function-general Eyring, etc., and estimates various reliability measures.

  • Purpose: The purpose of this study was to develop an integrated suicide violence prevention program for adolescents. Another purpose was to evaluate the effects of the integrated suicide violence prevention program on self-esteem, parent-child communication, aggression, and suicidal ideation in adolescents. Methods: The study employed a quasi -experimental design. Participants for the study were high school students, 24 in the experimental group and 25 in the control group. Data was analyzed by using the SPSS/WIN. 11.5 program with $X^2$ test, t-test, and 2-way ANOVA. Results: Participants in the integrated suicide violence prevention program reported increased self-esteem scores, which was significantly different from those in the control group. Participants in the integrated suicide violence prevention program reported decreased aggression and suicidal ideation scores, which was significantly different from those in the control group. Conclusion: The integrated suicide violence prevention program was effective in improving self-esteem and decreasing aggression and suicidal ideation for adolescents. Therefore, this approach is recommended as the integrated suicide violence prevention strategy for adolescents.

  • This study introduces an environmental noise evaluation procedure and results for a wind turbine (W/T) system. Test and evaluation are required by the international standard IEC 61400-11 in the aspect of environmental effect. Test and evaluation are performed on U-50 WT model which is first developed by the domestic W/T manufacturer. W/T test model is under operation in Daekwanryung wind test site. An integrated monitoring system in the test site is utilized for the evaluation. With the noise signal, meteorological data and W/T operational data are monitored in real time by the integrated monitoring system using LabVIEW. From the measured noise data, acoustic power level are estimated and compared with those of other similar size WT under the wind speeds required by international standard.

  • Purpose: This study examined the effects of an integrated activity program on the self-efficacy and depression of underprivileged elderly women living alone. Methods: The participants recruited were fifty underprivileged elderly women living alone in D city. Data were collected from September 1 to October 1, 2015. To test the effects of the integrated activity program, the participants were divided into two matched groups, an experimental group (N=25) and control group (N=25). The data were analyzed with a ${\chi}^2-test$, Fisher's exact probability test, and t-test using the SPSS/WIN 12.0 program. Results: After attending the integrated activity program, significant differences between the experimental group and control group were found for self-efficacy (t=9.19, p<.001) and depression (t=-18.31, p<.001). Conclusion: The results indicate that the integrated activity program enhances self-efficacy and reduces depression in underprivileged elderly women living alone. Therefore, this program is a good strategy that community mental health nurses can use to improve the mental health of underprivileged elderly women living alone.
