  • This study aims to analyze the usefulness of the survey procedures developed for telephone surveys using a random sampling method. We conducted a telephone survey of residents in a local area from October 26 to November18,2009. We applied random sampling procedures with five call-backs. Particular attention was given to the conversion of refusals. Out of 2,454 phone numbers, we succeeded in getting responses from 637 numbers. The absence of residents was the primary cause of non-response. We received responses from 45.7% of those with whom we successfully made contact. One finding of this study is that, contrary to our initial expectations, call-backs do not significantly increase the percentage of responses from young people. Also we cannot find any significant differences in responses to various questions between the responses received from the first round of calls and later responses. However, these results are not conclusive; another survey may produce different results. Therefore, further research is needed.

  • The purpose of this study was to systematically review music intervention studies for patients with schizophrenia. The researcher searched nine electronic databases for clinical trials published since 2000, using combinations of keyword related to schizophrenia and music interventions. The initial search identified 272 studies, and fifteen studies were selected by reviewing the titles, abstracts and full articles, In addition, three articles were added by examining other review articles. Thus, a total of 18 articles were analyzed in terms of their general and intervention characteristics, and the PEDro scale was used to evaluate the methodological quality of the included studies. The results demonstrated that, due to the lack of randomization and blinding, the methodological qualities of the studies with high quality music interventions were often rated low. Eight Music interventions conducted by qualified music therapists included active music-making, therapeutic relationship, and supervision systems for improving intervention quality. In conclusion, the randomization, blinding, and the therapeutic rationale of intervention are recommended in future clinical trials for patients with schizophrenia.

  • In this study, We developed VR (Virtual Reality) geological resources based on the Geo Big Data of the Big Data platform that provided by the Korea Institute of Geoscience and Mineral Material (KIGAM). So students selected the theme of lessons by using these resources and we operated Remote classes using the materials that developed as to Virtual Reality. Therefore, the geological theme maps provided by the Geo Big Data Open Platform were reconstructed and produced materials were created for Study about Real Korean geological outcrops grounded in Virtual Reality. And Topographic information data was used to produce class materials for Remote classes. Twenty students were selected by Random sampling, and data were collected by conducting a survey including interviews to confirm the change in students' perception of remote classes in virtual reality geological data development and the effect of the classes, so data were analyzed through inductive categorization. The results of this study are as follows. First, students showed positive responses in terms of interest, utilization, and knowledge utilization as taking remote classes for developing geological data in virtual reality geological data. This is the result of showing the adaptability of diverse and flexible learning getting away from a fixed framework by motivating and encouraging students and inducing cooperation for communication. Second, students recognized distance education in the development of Virtual Reality geological data as 'Realistic hands-on learning process', 'Immersive learning process by motivation', and 'Learning process of acquiring knowledge in the field of earth science'.

  • As is the case with South Korea, if the authority for decision making on curricula is concentrated on the state level, the perspective of the understanding on the curricula could be said to be essential. And, such an understanding on the curricula can be important not only to the theorist of curricula but also the teachers in educational institutions. Also, there have been a number of studies to examine the awareness of the teachers on education reform. However, the studies on the resistance factor was mainly focused on the relationships with traits of individuals, covering factors such as their habits, maturity, character, and age, etc. But, it was difficult to find consistency in the results of these studies. Therefore, in this study, the researcher selected the teachers as the key factor of the execution of the curricula and examined the awareness of the teachers on education resistance and the negative views thereupon in the relationship between the knowledge, attitude, skills, and education execution, with a view to find another meaning. The subjects of this study were selected among the teachers in middle or high schools located in Gangnam, Songpa, and Joonggu districts of Seoul. The survey was conducted online with 15 institutions over three weeks from April 13 to 30, 2018. The data gathered were analyzed using SPSS 20.0 and AMOS 20.0, in order to validate the hypotheses through frequency analysis, confidence analysis, factor analysis, structural equation model, and sobel-test. The result of the analyses showed that the factors that affected execution of curricula were the skill system, knowledge system, and attitude of the teachers, in that order, with a positively significant influence. And, significant differences were identified between the factors depending on high or low resistance among teachers.

  • This paper examined the electoral polling methodologies such as sampling method, sampling frame and the classification of the don't-know responses. Quota sampling method seemed to be one of the major factors for the declining trust in the poll results. We suggested that new procedures for random sampling as well as the bad number screening procedures for RDD selection of phone numbers need to be developed. Also we reviewed how the KBS used the polls in defining voters' agenda and in communicating the public agenda to the candidates. In Korea, rates for the polls were based mainly on the number of interviews completed. It seemed to keep the polling companies from tim new and more time-demanding polling methods. Also various utilization of the polls are limited by the tendency to keep the questionnaire short.

  • This thesis is a content analysis on whether the proportion of structural element and theme association of television news imagery is different, depending on the historical background, and on what it means, which can be the index of scene-based and realistic report. Most researches of television news are horizontal studies of the same period, making light of vertical studies reflecting the change of age. Therefore, This study analyzed 729 items composed of 11,945 shots extracted from MBC Newsdesk from 1987, to 2007, the samples of which were extracted by systematic random sampling with five years' interval. This content analysis found out that there was high proportion of scene-based and realistic report such as 'sound-bite', 'event footage', 'direct matching' in the year 1987, 2007, and high proportion of 'corroboration shot', 'file footage', 'indirect reference', 'literal matching only' in the year 1997, which revealed the fact that reality-based report had not been faithfully accomplished in 1997.
