  • Since the solution vector for input-output forecasting models is not directly obtainable, several iterative procedures have been proposed and utilized. As is often the case in numerical analysis, the question of the consistency between the original system and the converged system of the proposed iteration has been ignored, and no one has tried to express the converged solution explicitly. This paper examines this question and points out the inconsistencies between various well-known iterative procedures used to solve input-output models and the original input-output system.

  • In this paper, we investigate the impact of channel estimation error on the D2D power control algorithm. In the previous work, D2D power control algorithm has been proposed under the assumption that the channel between the transmitter and the corresponding receiver is perfectly estimated. In reality, the channel estimation error is more often the case. The first question is that the power control algorithm designed for perfect channel estimation is still valid under the channel estimation error environment ? The second question is, if it is not valid, what could be the possible remedy for the channel estimation error ? In this paper, to answer the first question, we investigate the impact of the channel estimation error on the power control algorithm. We first review the D2D power control algorithm designed for perfect channel estimation. Then, we model the channel estimation error. Finally, we summarize the main results observed from the analysis of the simulation.

  • Korean wh-questions and yes-no questions have morphologically the same structure. In speech, however, two types of questions are distinguished by prosodic difference. In this study, we examined if Korean native speakers can distinguish wh-question and yes-no questions produced by Chinese Korean leaners based on the prosodic information contained in the sentences. For this purpose, we performed perception analysis, and 15 Korean native speakers participated in the perception test. The results show that two types of interrogative sentences produced by Chinese Korean leaners were not distinguished by constant pitch contours. These results reveal that Chinese Korean leaners cannot match prosodic meaning and prosodic form. The most saliant prosodic feature used perceptually by native speakers to discriminate two types of interrogative sentences is pitch difference between the F0 pick of wh-word and boundary tone.

  • Purpose: The purpose of this study was to identify the relationship of resiliency and symptom experience and depression. Subjects (N=152) were patients with chronic obstructive pulmonary disease (COPD).admitted to D University Medical Center in B City. Methods: Data collection was conducted from July 20 to August 25, 2013. The levels of symptom, resilience, and depression were measured using a seven question symptom experience measuring instrument, a 25-question resilience instrument, and a 15-question Short Geriatric Depression Scale (SGDS). The collected data were analyzed by descriptive analysis, Pearson's correlation coefficients, and path analysis using SPSS/Win 19.0 and AMOS 5.0. Results: There was a significant negative correlation between symptom and resilience, a significant positive correlation between symptom and depression, and a significant negative correlation between resilience and depression. Symptom showed a direct effect on depression and an indirect effect on depression scores through resilience as a mediating variable. Conclusion: It is necessary to develop nursing intervention programs to relieve symptom in COPD patients, and to develop appropriate resilience enhancement programs to reduce their depression.

  • This paper was made for the purpose of examining middle school student's conception about force and motion. Using questionaire method. this research was executed to 180 students at a middle school in Seoul. Questions were as following; 3 questions about relation of the direction of force and that of motion in case of throwing a ball up, 2 questions about parabolic motion. 1 question about inertia. and 1 question about action and reaction. The way of answering was both selecting and explaining the students' thought about questions. Network analysis was used for analyzing students' various responses. Through the analysis. some types of students' thought were revealed. As a result the representation of their response was motion implies force which had been discovered by earlier researchers. Even though students had learned about force and motion in the classroom. their ideas were unchanged or even reinforced wrongly in some case.

  • Lately Construction industry depressed by hard construction market condition. So Construction company, especial at this time, make more rationalize the management of inside Company and Construction field. So in this study we are to present the method of calculation reasonable duration at Reinforced Concrete Work. For the study first make up a question at field workers, then sampling the Form workers based the question. Second, We are using Work Analysis Method analysing the worker's work-method and Time. And then using the result of analysis, measure the Productivity of Form work. The productivity of Form work is used the basic data of duration at Reinforced Concrete Work

  • The basic purpose of this research is to analyse a relationship between the integration level of AMT(ILAMT) and manufacturing performance (cost, quality, flexibility, delivery) and to identify the moderating effects of organizational structure in the relationship. First research question(hypothesis 1) was to examine the relationship between ILAMT and manufacturing performance. We tested this question using simple regression analysis. All of the correlation were positive and significant at the level of 1%(two-tail test). Therefore, hypothesis 1 was supported by the results. It means that firms that have high ILAMT are to exhibit high level of all manufacturing performance(cost, flexibility, quality, delivery). Namely, It is that the integration of AMT can solve the trade-off among manufacturing performance. Second research question (hypothesis 2) was to identify the moderating effects of organizational structure on the relationship between ILAMT and manufacturing performance. we tested this question using moderated regression analysis. According to the results, hypothesis 2 was partially supported. In other words, formalization and decentralization were accepted, but complexity was rejected. It means that firms with high ILAMT and an organic organizational structure are more likely to exhibit high level of manufacturing performance. To the practitioners, this research provided the answer to what they ought to do make AMT work in their organizations. To increase the effectiveness of AMT, first of all, they should take notice of the importance of integrated use of AMT, and the implementation of AMT should take into consideration the characteristics of organizational structure manufacturing strategy so that the effect of AMT may be multiplied by using AMT.
