  • This paper proposes a portable cable fault detection system with automatic fault distinction and distance measurement using time-frequency correlation and reference signal elimination method and automatic fault classification algorithm in order to have more accurate fault determination and location detection than conventional time domain refelectometry (TDR) system despite increased signal attenuation due to the long distance to cable fault location. The performance of the developed system method was validated via an experiment in the test field constructed for the standardized performance test of power cable fault location equipments. The performance evaluation showed that accuracy of the developed system is less than 1.34%. Also, an error of automatic fault type and location by detection of phase and peak value through elimination of the reference signal and normalization of correlation coefficient and automatic fault classification algorithm not occurred.

  • The major purpose of this study was analyzing of farmer's intention in related to organic agriculture by using of the Theory of Planned Behavior (TPB). Farmers of Chungchung Province (n=164) were administered a questionnaire survey that measured TPB constructs. The data and hypotheses were analyzed using multiple regression and confirmatory factor analysis by SPSS 21.0 and AMOS 21.0. Results showed that attitude, subjective norms, and perceived behavior of control were all positively related to farmer's intention of organic agriculture and explained power of the model was relatively high which was 51 percent. Also the results of the analysis showed that the subjective norm was a key dimension of farmer's intention in terms of standardized coefficient. The study demonstrated that the reduced theory of planned behavior was fit for factors of farmer's intention. The meaning of the study and implications for future studies were discussed.

  • Given the prevalence of internet and web 2.0, SNS(Social Network Service) market is growing rapidly. IT providers which focused marketing point on network hub have become to disseminate SNS mainly now. Many users are using the various functions of SNS to communicate each other or share the information. At this point, identifying the influencing factors to WOM(Word-Of-Mouth) of SNS is very important. In this paper, we aim to examine the effects of perceived variables on the WOM of SNS. In order to analyze the antecedents, we selected perceived factors such as perceived usefulness, perceived easiness, perceived enjoyment and perceived crowd. For statistical analysis, we surveyed real users of SNS. As a result, all antecedents of WOM showed significant influence and among the variables the perceived enjoyment has top standardized coefficient. In addition, perceived crowd has significant on perceived easiness, perceived enjoyment but not on perceived usefulness. The result of this research can be useful guidelines to increase SNS Market.

  • Current loads acting on offshore vessels are important for predicting the hydrodynamic and structural responses of the vessels. It is also true for analyzing the behavior of moored systems under the action of ocean current. Unfortunately there are few standardized current load coefficients for offshore vessels and it is extremely difficult to be applied to arbitrary hull shapes, if any. Therefore current load coefficients for three hull shapes are calculated in this study using a CFD code, which is well known in the shipbuilding industry. In order to validate the present approach, a typical VLCC is taken as numerical example and resulting current coefficients are compared with experiment together with the OCIMF data. The comparison shows a good agreement in the qualitative sense. Two additional models considered herein are a shuttle tanker and a FPSO under deepwater condition $(WD/T{\geq}6)$. The present numerical approach may be utilized for practical design of offshore vessels.

  • The fatigue life of support bearings is one of the most critical factors for the performance of a control rod driving mechanism. They are operated at high temperature and high pressure and especially lubricated with dramatically low viscosity water. The support bearing is made of standardized 440C stainless steel, and it supports thrust load including the weight of the driving system and external force. Friction and wear characteristics of this material operating under severe lubrication condition is not well known yet, although it is expected to be changed with respect to temperature and boundary pressure. So the friction characteristics are investigated in sliding conditions using the reciprocating tribometer which can simulate the operating conditions. Highly purified water is used as lubricant, and the water is heated up and pressurized. Friction farce on the reciprocating specimens is monitored by the load cells. The results of the experiments are presented in this paper.

  • Objectives: This study aims to supplement the limitations of the preliminary study and expand the use of the Child-Adolescent Functional Assessment Scale by providing standardized T-scores for measuring function in different areas, as well as guidelines for their interpretation. Methods: The Child-Adolescent Functional Assessment Scale and Korean-Child Behavior Checklist were administered to a total of 623 individuals, including 467 parents of emotionally and behaviorally disturbed elementary school students, 45 parents of emotionally and behaviorally disturbed middle school adolescents and 111 parents of elementary school students with developmental disorders, as well as to a control group consisting of 186 parents of mainstream elementary school children in the Seoul metropolitan area. Results: In contrast to the preliminary study, the emotional domain was disassociated into two factors, negative affect and emotion regulation, and the coefficient of determination for misconduct was increased significantly. Also, the overall reliability and validity of the Child-Adolescent Functional Assessment Scale were similar to those in the preliminary study, and the item structure was consistent. This study provides standardized T-scores of function in different areas based on the revised scale, and provides guidelines for their interpretation. Conclusion: The Child-Adolescent Functional Assessment Scale can assist the Child Global Assessment in Functioning in providing the information necessary for case management and treatment planning by comparing the impairment severity in each area of functioning, and also determining changes in behavior and function after treatment interventions. On the other hand, this scale has yet to clearly distinguish between rebellious behavior and misconduct. Further research is necessary to provide standards for more diverse age groups and for its utilization.
