  • In this study, we introduce the background and model for the Test of Practical Competency in ICT(TOPCIT), which is designed to diagnose and assess the competency of ICT industry related workers and software(SW) developers, and also attempt to derive meaningful policy implications for developing a global level of ICT SW competency evaluation system across the different cases in domestic and foreign countries with regard to the application and dissemination of the TOPCIT. First, we analyze the test results from surveys conducted a preliminary test (or a pilot test) for the process of global dissemination of the TOPCIT in 2015. Then, we attempt to compare the results with the domestic test results. The findings show that the average score between domestic and foreign test takers was similar, but in the highest score group, the number of domestic test takers was relatively higher than the number of foreign test takers. Moreover, the average score can be varied by the language ability, especially fluent in English, of test takers. Therefore, the findings suggest that the localization is one of the key components for building upon the global TOPCIT system.

  • The role of fly ash in concrete become impotent with finding the characteristics of fly ash in which it is used as cement replacement material. In this paper, corrosion test results obtained by two test methods such as the long-term exposure corrosion test and the accelerated corrosion test method, were compared to investigated the corrosion resistance between fly ash concrete and normal concrete. Corrosion initiation time was measured in two types of concrete, i.e., one mixed with fly ash(FA) and the other without admixture(OPC). The accelerated corrosion test was carried out by four case, i.e., two samples is a cyclic drying-wetting method combined without carbonation(case 1) and combined with carbonation(case 2), and the other two samples is a artificial seawater ponding test method combined without carbonation(case 3) and combined with carbonation(case 4). Whether corrosion occurs, it was measures using half-cell potential method. The ponding test combined without carbonation was most effective in accelerating corrosion time of steel bars. The results indicated that the corrosion of rebar embedded in concrete occurred according to the order of OPC, FA. The delay relative ratio of corrosion obtained by corrosion initiation time between FA and OPC is 1.04 to 1.27. Consequently, fly ash concrete as the age increases its corrosion resistance was improved compared with OPC concrete.

  • Many existing test case generation researchers extract test cases from models. However, research on generating test cases from natural language requirements is required in practice. For this purpose, the combination of natural language analysis and requirements engineering is very necessary. However, Requirements analysis written in Korean is difficult due to the diverse meaning of sentence expressions. We research test case generation through natural language requirement definition analysis, C3Tree model, cause-effect graph, and decision table steps as one of the test case generation methods from Korean natural requirements. As an intermediate step, this paper generates test cases from C3Tree model-based decision tables using meta-modeling. This method has the advantage of being able to easily maintain the model-to-model and model-to-text transformation processes by modifying only the transformation rules. If an existing model is modified or a new model is added, only the model transformation rules can be maintained without changing the program algorithm. As a result of the evaluation, all combinations for the decision table were automatically generated as test cases.

  • The purpose of this study is to derive the need to improve the test and evaluation(T&E) performance system of the weapon systems to which advanced science and technology is applied, evaluate priorities, and present development plans. T&E of Al-based weapon systems through a literature research and case analysis on changes in the T&E environment for weapon system, 11 detailed evaluation items were derived from the in terms of the T&E system, structure, and technology. Al-based weapon system test evaluation should be performed in parallel with data-based performance evaluation and actual T&E, and performance measurement using a separate T&E data set is required for AI models performance evaluation. As a result of analyzing the importance of T&E through AHP analysis, the order of T&E system-technology-structure was evaluated, and the priority of detailed evaluation items was evaluated in the order of T&E result judgment-T&E organization and expert training-scientific T&E. For evaluation items with high priority, measures to improve the T&E performance system were presented.

  • Interfacial evaluation, damage sensing and cure monitoring of single carbon fiber/thermo setting composite with different curing processes were investigated using electro-micromechanical test. After curing, the residual stress was monitored by measurement of electrical resistance and then compared to various curing processes. In thermal curing case, matrix tensile strength, modulus and interfacial shear strength were higher than those of ultraviolet curing case. The shrinkage measured during thermal curing occurred significantly by matrix shrinkage and residual stress due to the difference in thermal expansion coefficient. The apparent modulus measured in the thermal curing indicated that mechanical and interfacial properties were highly improved. The reaching time to the same stress of thermal curing was faster than that of UV curing case.

  • Objective : To explore the effectiveness of sensory integration program of home-based outcomes in child with sensory modulation disorder. Methods : This study used the simple case study. The subjects were three children diagnosed as developmentally delayed who 14 month and 26 month males and a 15 month female. After initial evaluation, parents were educated on sensory diet and Wilbarger protocol method for 30 minutes twice for home-based treatment and asked to make out daily treatment planning. To measure improvement of children, we used for the Denver Developmental Screening Test II(DDST II), Wee Functional Independence Measure(WeeFIM), hand function, functional ability, oral motor function, Sensory Profile(Dunn, 1999). Results : After the home-based program, the scored of the Denver Developmental Screening Test II(DDST II), Wee Functional Independence Measure(WeeFIM), hand function, functional ability, oral motor function, Sensory Profile(Dunn, 1999) were higher rather than initial evaluation after the home-based program. Conclusion : The home-based program is effective for children with sensory modulation disorder but parents had to be educated by therapist specific evaluation and treatment in sensory integration.

  • In this study, the reinforced concrete rahmen bridge damaged by the chloride attack was investigated. According to the investigation, the degraded concretes on cantilever kerb and end part were intensively observed. Thus, the chloride content test and half-cell method were performed to evaluate the degraded parts. As a result, the contents of chloride on degraded parts were C and D grade. On the other hand, the half-cell potential values of rebar in degraded concrete were measured with the minor corrosion. This rebar corrosion is expected to progressing. Chloride content D grade is due to expansion pressure by corrosion of rebar and freeze-thaw by permeate water, could see progresses rapidly degradation. In order to prevent chloride attack to concrete deck caused by deicing salts, corresponding to the chloride critical concentration must maintain grade b or at least grade c. Chloride condition evaluation standard apply to evaluation of marine structure chloride attack with chloride attack by deicing salts.

  • Objectives: The Purpose of this study is to report three cases on tension-type headache treated by Chuna manipulative therapy. Methods: Three patients diagnosed tension-type headache were treated with Chuna manipulative therapy only. To evaluate effect of treatment, visual analogue scale(VAS) and headache impact test(HIT) were used. We checked VAS and HIT score three times(pretreatment, post-treatment, follow-up). An interval among each evaluation time is 4 weeks. Results: At post-treatment evaluation, VAS and HIT score declined significantly compared with pre-treatment. At follow-up evaluation, the pain did not increased. Conclusions: These results suggests that Chuna manipulative therapy may be effective for tension-type headache.
