  • The introduction of educational programming language has changed programming learning environment to learn programming through various learning activities. We need to analyze how effective these learning activities could be in programming learning. We performed a meta analysis of the programming learning effects according to 8 types of learning activities. The 44 studies were collected from 1993 to 2015 for the meta analysis. The study data of 77 were extracted among 44 studies through several steps. The major results were as follows. The effect size of cognitive domain was shown to be mid-level with .595 and the effect size of affective domain was shown to be mid-level with .594. We analysed according to learning activities. The effect size were no significant difference between learning activities in the cognitive domain. But simulation, animation and mathematical activities was shown to be more consistent results and mid-level effect size. Although the effect size were no significant difference, the homogeneity was shown to be high in the affective domain. The implications were suggested from research findings. First, it is desirable that learners learn programming according to various learning activity themes. Second, instructors should pay attention to simulation, animation and mathmatics activities. Third, researchers need research to find another factors for effective learning.

  • In case of observing only wave height and period in the field, various wave characteristics are mainly calculated by wave by wave analysis method. In this paper, an wave by wave analysis program using MATLAB language is developed. It is possible to perform a function such as 1) correction for mean water level, 2) calculation for zero crossing time, 3) calculation for individual wave height, 4) time interval by using zero upcrossing and downcrossing method. The applicability of the developed program to the data of 0.2 second interval observed by using the WaveGuide Radar installed on HeMOSU-1 was examined. Tidal level variation removal and zero crossing time estimation were determined by linear or quadratic interpolation. It was judged that the Goda method was appropriate for calculating individual wave height, and the method proposed in this study seems to be improved through subsequent research. Due to the fineness of the sample, it can be seen that characteristics of representative waves are different from the results calculated by zero upcrossing and downcrossing method.

  • In Korea, the major of international trade and business introduced in the 1960s to supply trade expert to trading companies, and the heyday of the trade major was in the 1980s. However the trade major fell into decay from the middle of 1990s. The purpose of trade education in university is to supply high qualified employees to societies and companies. The problem is that companies have difficuties for recruiting of trade expert, on the other hand university graduates have few job oppertunies. It has some discrepancies between education and field. The object of this paper is to propose a direction of modification of the trade and international business curriculum for global trade expert. We research international trade and business departments' curriculums of GTEP universities. GTEP stands for global trade expert incubating program started from 2006 which have charge of MOCIE and KITA. First, in the title of department, a lot of former researchers have taken up the position to return "Trade" or "International Trade". We think more important fact is not the title of department but the curriculum, so we insist on a harmony between the department title and curriculums. The focus of modification of curriculum is to educate global trade expert, so we need to know about global business environment and companies' needs also. Second, We propose the directions for modification of curriculum are "convergence" and "specialty". Trade major is a mixed study in nature and trade major try to treat lots of subjects such as trade, business adminstration, economics, international law, international commerce, logistics and marketing etc to catch up changing global business circumstanses and companies' needs. So convergence of adjacent field is very important in study and training. Specialty means selection and concentration strategy for global trade expert. It is difficult to learn every knowledge and skills for employer's needs in 4 years and 140 credits. A students who has studied basic subject in trade, management, economics can choose 1 or 2 specailty subject such as trade and e-commerce, global marketing, logistics and transportation, commerce and policy, servive trade, foreign language and cross culture etc. In concusion, the concept of convergence and specialty is not separation but harmony each other, so we propose to promote two concept together for modification of the trade and international business curriculum for training of global trade expert.

  • The purpose of this study was to analyze high schools' general and special subject required to successfully complete same stream curriculum which is identical to their major from agricultural high school, and to offer basic data on strategies of organizing agricultural high schools' curriculum for improving universities' major basic competencies. Using purposeful sampling technique, the professors of 116 universities professors in 8 agricultural university were analyzed through the survey research. The result was as follows. first, it appeared that for successful completion of major subjects of the same stream university, the basic science subject such as biology and chemistry has high relation with major basic ability, however math and physics are related highly in agricultural machine and agricultural civil engineering department, economics and math are in agricultural produce distribution department. Second, the basic ability such as linguistic competence and foreign language ability are essential to complete major subject. Third, if we look into relation of agriculture and life science industry stream specialized subject with major basic competencies, we can find considerable similarity between major field of university and subject name of specialized high school. Fourth, the main opinion is that basic concept and principle, laws of nature are should be main contents which is able to be practical, however experiment and practice is in food processing department, and academic theory is in biotechnology department.

  • The landscape of the education market is changing. As part of efforts to deal with the decrease of a school-age population in Korea, Korean universities and colleges are endeavoring to attract foreign students. Chinese students, the largest share of foreign university students in Korea, are becoming an important element at Korean universities and colleges. Chinese students face various kinds of difficulties while trying to cope with new environments in the country. This study aims to analyze the impact of academic factors and psychological factors of Chinese students on the level of adaptation to university life and their satisfaction with it. Data on 128 Chinese students attending D University located in Busan were collected and a path analysis was conducted using partial least squares (PLS) regression. Research results are as follows. First, professors as an academic factor and the level of interest of university staff have significant impact on the level of adaptation to university life while Korean language proficiency does not have significant impact on the level of adaptation to university life. Second, homesickness as a psychological factor is correlated to the level of adaptation to university life with significance while acculturative stress is not correlated to it. Third, the level of adaptation to university life is correlated to the level of satisfaction with university life. Based on these findings, the significance, limitations and future directions of this study are discussed.

  • The purpose of this study is to explore the internal foundation of lifelong education for the disabled. The composition system of the meaning of contents for this purpose is divided into three elements: 'of' which means subject based on lifelong education for the disabled, 'for' which means purpose, and 'from' which means practical main base. The research method was to discuss the academic basis, practical application model and plan, or to analyze the literature through the previous studies that were actualized in order to form the internal foundation of the support system for lifelong education for the disabled. Second, the expert meeting was conducted to improve the specificity of the research contents based on the basis of the literature analysis. The contents of this study are presented in two main ways: the foundation of developmental disabilities and the foundation of schools by synthesizing the main bases of subjects, purposes, and practical base required to form the internal foundation of lifelong education for the disabled. The above two factors first establish the internal universality of the support system for lifelong education for the disabled, and in connection with the types of sensory disabilities and the general lifelong education. As a result, the long-term stability of the overall support system for lifelong education for the disabled was analyzed.

  • In this study, trends in ICT education were investigated by analyzing the frequency of appearance of keywords related to machine learning and using conversion of iteration correction(CONCOR) techniques. A total of 304 papers from 2018 to the present published in registered sites were searched on Google Scalar using "ICT education" as the keyword, and 60 papers pertaining to ICT education were selected based on a systematic literature review. Subsequently, keywords were extracted based on the title and summary of the paper. For word frequency and indicator data, 49 keywords with high appearance frequency were extracted by analyzing frequency, via the term frequency-inverse document frequency technique in natural language processing, and words with simultaneous appearance frequency. The relationship degree was verified by analyzing the connection structure and centrality of the connection degree between words, and a cluster composed of words with similarity was derived via CONCOR analysis. First, "education," "research," "result," "utilization," and "analysis" were analyzed as main keywords. Second, by analyzing an N-GRAM network graph with "education" as the keyword, "curriculum" and "utilization" were shown to exhibit the highest correlation level. Third, by conducting a cluster analysis with "education" as the keyword, five groups were formed: "curriculum," "programming," "student," "improvement," and "information." These results indicate that practical research necessary for ICT education can be conducted by analyzing ICT education trends and identifying trends.

  • The purpose of this study is to discover unique personality traits which the children of 5 social status types using 10 clinical scales of Korea Children's personality test (KCPI-S) in order to define the characteristics of 5 social status types developed as the Korean type. For this purpose, two hypotheses were set and tested. The subjects of this study were 502 children who were 4, 5th and 6th grade elementary school boys and girls in A city. 5 social status types and gender of children were set as the independent variables each, and 10 clinical scales of Korea Children's personality test as the dependent variables. The research hypotheses were analyzed in turn by the multivariate analysis (MANOVA) and t-test. The results are as follows: First, the results of analyzing differences in 10 clinical scales in accordance with 5 social status types how the significant differences in all 9 clinical scales except for language development scale, and ${\eta}^2$ representing the explanatory power of the independent variables to dependent variables was found to be in the range of the lowest at 2% up to 10% for each scale. Second, the results of analysis of the gender difference show that in the case of the children with controversial and neglected children, the significant difference was appeared between boys and girls in 8-9 scales among the 10 clinical scales, but in the case of rest 3 social status types (average, popular, rejected children) the difference was appeared between boys and girls only in 2-3 scales. Depending on these results it seems that each of 5 social status types of the children has its own unique personality structure. It is necessary to attend to the fact that in the case of the children with controversial and neglected children, the average value of boys are significantly higher than that of the girls. There is a big possibility that the boys have more psychological problems that the girls. It is judged that in case of these two types the personal traits applying gender should be interpreted. Therefore, the follow-up study should conduct the exploratory research on the structure of the relationship between children's language development and sociality measure. Further, it is necessary to conduct the psychological comparison between genders in the children with controversial and neglected children, and to study the structure of their relationship with rest social status types by genders.

  • I. Research Objectives: Most of the previous studies on diffusion have concentrated on efficacy of WOM communication with the use of variables at individual level (Iacobucci 1996; Midgley et al. 1992). However, there is a paucity of studies which investigated network's structural properties as antecedents of WOM from the perspective of consumers' sociocultural propensities. Against this research backbone, this study attempted to link the network's structural properties and consumer' WOM behavior on cross-national basis. The major research objective of this study was to examine the relationship between network properties and WOM by comparing Korean and Chinese consumers. Specific objectives of this research are threefold; firstly, it sought to examine whether network properties (i.e., tie strength, centrality, range) affect WOM (WOM intention and quality of WOM). Secondly, it aimed to explore the moderating effects of cutural orientation (uncertainty avoidance and individuality) on the relationship between network properties and WOM. Thirdly, it substantiates the role of innovativeness as antecedents to both network properties and WOM. II. Research Hypotheses: Based on the above research objectives, the study put forth the following research hypotheses to validate. ${\cdot}$ H 1-1 : The Strength of tie between two counterparts within network will positively influence WOM effectivenes ${\cdot}$ H 1-2 : The network centrality will positively influence the WOM effectiveness ${\cdot}$ H 1-3 : The network range will positively influence the WOM effectiveness ${\cdot}$ H 2-1 : The consumer's uncertainty avoidance tendency will moderate the relationship between network properties and WOM effectiveness ${\cdot}$ H 2-2 : The consumer's individualism tendency will moderate the relationship between network properties and WOM effectiveness ${\cdot}$ H 3-1 : The consumer's innovativeness will positively influence the social network properties ${\cdot}$ H 3-2 : The consumer's innovativeness will positively influence WOM effectiveness III. Methodology: Through a pilot study and back-translation, two versions of questionnaire were prepared, one in Korean and the other in Chinese. The chinese data were collected from the chinese students enrolled in language schools in Suwon city in Korea, while Korean data were collected from students taking classes in a major university in Seoul. A total of 277 questionnaire were used for analysis of Korean data and 212 for Chinese data. The reason why Chinese students living in Korea rather than in China were selected was based on two factors: one was to neutralize the differences (ie, retail channel availability) that may arise from living in separate countries and the second was to minimize the difference in communication venues such as internet accessibility and cell phone usability. SPSS 12.0 and AMOS 7.0 were used for analysis. IV. Results: Prior to hypothesis verification, mean differences between the two countries in terms of major constructs were performed with the following result; As for network properties (tie strength, centrality and range), Koreans showed higher scores in all three constructs. For cultural orientation traits, Koreans scored higher only on uncertainty avoidance trait than Chinese. As a result of verifying the first research objective, confirming the relationship between network properties and WOM effectiveness, on Korean side, tie strength(Beta=.116; t=1.785) and centrality (Beta=.499; t=6.776) significantly influenced on WOM intention, and similar finding was obtained for Chinese side, with tie strength (Beta=.246; t=3.544) and centrality (Beta=.247; t=3.538) being significant. However, with regard to WOM argument quality, Korean data yielded only centrality (Beta=.82; t=7.600) having a significant impact on WOM, whereas China showed both tie strength(Beat=.142; t=2.052) and centrality(Beta=.348; t=5.031) being influential. To answer for the second research objective addressing the moderating role of cultural orientation, moderated regression anaylsis was performed and the result showed that uncertainty avoidance moderated between network range and WOM intention for both Korea and China, But for Korea, the uncertainty avoidance moderated between tie strength and WOM quality, while for China it moderated between network range and WOM intention. And innovativeness moderated between tie strength and WOM intention for Korea but it moderated between network range and WOM intention for China. As a result of analysing for third research objective, we found that for Korea, innovativeness positively influenced centrality only (Beta=.546; t=10.808), while for China it influenced both tie strength (Beta=.203; t=2.998) and centrality(Beta=.518; t=8.782). But for both countries alike, the innovativeness influenced positively on WOM (WOM intention and WOM quality). V. Implications: The study yields the two practical implications. Firstly, the result suggests that companies targeting multinational customers need to identify segments which are susceptible to the positive WOM and WOM information based on individual traits such as uncertainty avoidance and individualism and based on that, develop marketing communication strategy. Secondly, the companies need to divide the market on Roger's five innovation stages and based on this information, enforce marketing strategy which utilizes social networking tools such as public media and WOM. For instance, innovator and early adopters, if provided with new product information, will be able to capitalize upon the network advantages and thus add informational value to network operations using SNS or corporate blog.
