Malfunction by electrical surges is a serious problem on earth leakage current breakers(ELBs) used in a low voltage AC power system. In this paper, we tested ELBs according to IEC 61009-1 and KS C 4613 to analyze surge influence on ELB's malfunction. The test by application of surge voltage is specified both standards, but the test by application of surge current is specified only in IEC 61009-1. The experimental results showed that the ELBs used in this test are robust to surge voltage application, but the malfunction occurred to surge current application. Surge current is more frequent than surge voltage in actual situation. Therefore, ELBs should be tested by the surge current, and the domestic standard, KS C 4613, should includes a test procedure by the surge current application.

The optical sensors of Electro-Optical Camera (EOC) and Ocean Scanning Multi-spectral Imager (OSMI) aboard the KOrea Multi-Purpose SATellite (KOMPSAT) will be placed in a sun synchronous orbit in late 1999. The EOC and OSMI sensors are expected to produce the land mapping imagery of Korean territory and the ocean color imagery of world oceans, respectively. Utilization of the EOC and OSMI data would encompass the various fields of science and technology such as land mapping, land use and development, flood monitoring, biological oceanography, fishery, and environmental monitoring. Readiness of data support for user community is thus essential to the success of the KOMPSAT program. As a part of testing such readiness prior to the KOMPSAT launch, we have performed the preliminary acceptance test for the KOMPSAT data processing system using the simulated EOC and OSMI data sets. The purpose of this paper is to demonstrate the readiness of the KOMPSAT data processing system, and to help data users understand how the KOMPSAT EOC and OSMI data are processed, archived, and provided. Test results demonstrate that all requirements described in the data processing specification have been met, and that the image integrity is maintained for all products. It is however noted that since the product accuracy is limited by the simulated sensor data, any quantitative assessment of image products can not be made until actual KOMPSAT images will be acquired.

Using the intent of the Android application, an application can execute other application's components. However, if interaction between these components are not processed normally, such problems as incorrect component execution and unhandled system broadcast may be occurred. In this paper, to generate test scenarios for inter application interaction, a testing approach is proposed using a merged intent list and a single merged diagram. The proposed method can effectively be carried out to check the abnormal interaction among the applications which was not considered in existing testing approaches.

Background: To compare pain perception during palatal injection administration in children aged 7-9 years while using pre-cooling of the injection site versus application of topical anesthesia as a pre-injection anesthetic during the six months. Method: A prospective randomized split-mouth crossover trial was conducted among 30 children aged 7-9 years, who received topical application of either a pencil of ice (test group) or 5% lignocaine gel (control group) for 2 min before injection. The primary and secondary outcome measures were pain perception and child satisfaction, measured by the composite pain score and the faces rating scale, respectively. Unpaired t-test was performed to determine significant differences between groups. Results: The test group had significantly lower pain scores for self-report and behavioral measures (P < 0.0001). The changes in physiological parameters at the baseline (P = 0.74) during (P = 0.37) and after (P = 0.88) the injection prick were not statistically significant. Children felt better by the pre-cooling method (P < 0.0001). Conclusion: Ice application using a pencil of ice for 2 min reduced pain perception significantly compared to the use of a topical anesthetic. Moreover, ice application was preferred by children.

Watertight 25.8 kV/600 A/12.5 kA fault current limiters (FCLs) have successfully installed in five areas (Incheon, Seoul, Gyeong-gi, Daejeon, Suwon) on KEPCO power distribution line for the purpose of commercial demonstrations. The fault current limiting operation of this FCL, which includes functions of sensing, commutation, and reduction of fault currents, is perfectly completed within 1 cycle immediately after fault occurs. The performance of FCL was verified by short circuit test, impedance test, insulation test, temperature-rise test, and control test, etc at PT&T in LS industrial systems, which is the official certification institute in Korea. In 2013, and also the FCL field test was performed in order to test the protection coordination between conventional relays and FCL, on the 1.5 kA and 5.0 kA faults, which were made by connecting the Artificial Fault Generator (AFG) to the distribution line in test grid at KEPCO Power Testing Center. The next step of this project is to check the FCL conditions caused by real external environment, and acquire the various data from five regions installed with FCL. In this paper, we intend to explain the FCL specifications and performance characteristics, and check the expected effect by application of FCL to power distribution line based on the power system analysis of an application site.

Purpose: The purpose of this study was to investigate the effects of a profanity intervention application on interpersonal relationship ability, aggression, and empathic ability among female middle school students. Method: The subjects of the present study were freshmen students at a girls' middle school in Gyeonggi-do. The profanity intervention application was implemented from November 20th to 27th, 2017. The pre- and post-tests were conducted one week before and two weeks after the intervention, respectively. The study was designed as a randomized controlled study and the collected data were analyzed using SPSS/WIN 23.0 (Chicago, IL). A homogeneity test between the two groups was performed using $x^2$ test, Fisher's exact test, independent t-test, and ANCOVA. Results: The two groups were found to be homogeneous in the pre-test. After the implementation of the profanity intervention application, aggression significantly decreased (F=20.17, p<.001) and interpersonal reactivity (F=5.92, p=.023) and empathy (F=11.10, p=.003) significantly increased in the experimental group compared to the control group. Among the factors related with aggression, verbal aggression, anger, and hostility significantly decreased in the experimental group. Meanwhile, among the factors of interpersonal reactivity, empathic concern and perspective-taking significantly increased and, among the factors of empathy, cognitive empathy significantly increased in the experimental group compared to the control group. Conclusion: Based on the findings of the present study, various intervention programs that can consistently improve the moral and ethical sensitivity of students should be presented starting from elementary school to prevent verbal violence in adolescents.
