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 study uses a large language model (LLM) to identify Aristotle's rhetorical principles (ethos, pathos, and logos) in COVID-19 information on Naver Knowledge-iN, South Korea's leading question-and-answer community. The research analyzed the differences of these rhetorical elements in the most upvoted answers with random answers. A total of 193 answer pairs were randomly selected, with 135 pairs for training and 58 for testing. These answers were then coded in line with the rhetorical principles to refine GPT 3.5-based models. The models achieved F1 scores of .88 (ethos), .81 (pathos), and .69 (logos). Subsequent analysis of 128 new answer pairs revealed that logos, particularly factual information and logical reasoning, was more frequently used in the most upvoted answers than the random answers, whereas there were no differences in ethos and pathos between the answer groups. The results suggest that health information consumers value information including logos while ethos and pathos were not associated with consumers' preference for health information. By utilizing an LLM for the analysis of persuasive content, which has been typically conducted manually with much labor and time, this study not only demonstrates the feasibility of using an LLM for latent content but also contributes to expanding the horizon in the field of AI text extraction.

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.

Research Purpose - The purpose of this study was to investigate marketing stimulation and impulsive buying of Internet shopping mall. Research Question - Despite these unstable factors, the Internet shopping mall market has become more popular than traditional distribution channels such as department stores and discount stores due to the increase in the number of Internet users, a gradual increase in the consumption of high-priced items. Research Method - The data were collected from 301 women living in Seoul, Gyeonggi, Gwangju, Daegu, and Gyeongnam province in Korea on May 2018. Statistical methods used in the study were frequency, F-test, Duncan test, factor analysis, Cronbach's α, correlation coefficient, and multiple regression. Result - All The reliability of these questions is Cronbach's α =. 775. Factor 5, which is 12.367 % explanatory power, is said to consist of three questions: price, discount bag, and no-carrying; thus, the reliability of the question is Cronbachs' α. The ratio of the five factors in body random cases was 66.096 %, and the reliability of the questions was higher than. 770 as a result of the reliability analysis.

Objectives: The purpose of the study is to investigate the musculo-skeletal pain prevalence and severity in the dental hygienists based on PRECEDE model. Methods: A self-reported questionnaire was completed by 483 dental hygienists in Gwangju from September 13 to October 12, 2013. Data were analyzed by frequency analysis, chi-square test, t-test, and multiple logistic regression analysis using SPSS 18.0 program. Musculo-skeletal pain severity was classified from 1 to 5 by PRECEDE model. The questionnaire consisted of six questions of the general characteristics of the subjects, one question of musculo-skeletal pain prevalence, one question of body part musculo-skeletal pain prevalence, one question of subjective health status, three questions of activities of daily living, six questions of working environment, one question of musculoskeletal system diseases knowledge, two questions of social support, two questions of education experience and data use method, and five questions of necessity of health education. Results: The prevalence rate of musculo-skeletal pain within a year was 83.9% and 22.8% of the dental hygienists complained of severe pain. The odds ratio of moderate pain severity was 1.99(95% CI, 1.10-3.60) and the odds ratio of unhealthiness was 3.27 (95% CI, 1.35-7.94). The odds ratio of pain severity in those working for 4-6 years was 0.21(95% CI, 0.08-0.57). The odds ratio of pain severity in those practicing 6-10 scaling cases per day was 0.33(95% CI, 0.17-0.65). The odds ratio of pain severity in wrist turning and bending was 3.56(95% CI, 1.19-10.62). Conclusions: The muscolu-skeletal pain severity in the dental hygienists was closely associated with subjective health condition, work duration, the number of scaling practice activity, and a treatment posture. Regular physical checkup for the dental hygienists will improve the musculo-skeletal pain due to scaling practice.

본 연구의 목적은 대학생의 학습자 생성 질문수준, 질문과정 및 질문저해요인 간 관계를 파악하기 위함이다. 연구 대상자는 2015년 9월 9일부터 10일까지 D시에 소재하는 일개대학의 대학생을 편의추출 하였으며, 174명을 대상으로 하였다. 자료는 SPSS WIN 21.0 프로그램을 이용하여 빈도, 백분율, 평균 및 표준편차, t-test, ANOVA, Correlation analysis를 분석하였다. 대상자는 개인의 다양한 수준들을 통하여 질문을 생성하게 되면서도 인지적 혼란을 통한 질문생성은 실제질문과 관련함을 알 수 있다. 또한 질문저해요인의 내적요인은 실제질문과 음의 상관관계를 보인다. 즉 대학생의 질문이 잘 표출되기 위해서는 학습자의 질문을 주저하는 외적요인 뿐만 아니라 내적요인을 감소하기 위하여 고민이 필요할 것이다. 또한, 인지적 혼란-질문생성-실제질문의 연계성을 인식하여 교수 개인 차원의 효율적인 교과목 운영이 이루어져야 할 것으로 생각된다.
