  • The purpose of this study was to analyze the terms of astronomy area used in six convergence science textbooks by 2009 curriculum revision. The results of this study were following; the first, the contents about astronomy occupied about 18.6% account of science contents. There were the terms which all textbooks used, but some terms were not used other text book, and the others were used in only one textbook. And the second, there were some terms of having certain concept which had described differently. It was suggested that it was necessary to the effort to prevent to descript same meaning terms differently and to make guideline for the depth and width of the terms.

  • Data from repeated measurements are accomplished through repeatedly processing the same subject under different conditions and different points of view. The power of testing enhances the choice of pertinent analysis methods that agrees with the characteristics of data concerned and the situation involved. Along with the clinical example, this paper compares the analysis of the variance on ex-post tests, gain score analysis, analysis by mixed design and analysis of covariance employable for repeating measure. Comparing the analysis of variance on ex post test, and gain score analysis on correlations, leads to the fact that the latter enhances the power of the test and diminishes the variance of error terms. The concluded probability, identified that the gain score analysis and the mixed design on interaction between "between subjects factor" and "within subjects factor", are identical. The analysis of covariance, demonstrated better power of the test and smaller error terms than the gain score analysis. Research on four analysis method found that the analysis of covariance is the most appropriate in clinical data than two repeated test with high correlation and ex ante affects ex post.

  • The strength design actually carries an inconsistency where the structural analysis is being viewed in terms of elastic while the design is being drawn up in terms of plastic. In this study, in order to extend the applicability of the strength design, MRFEA(Moment Redistribution Finite Element Analysis) is developed. After carrying out the application example, it is found the use of materials was reduced compared to the elastic analysis.

  • The maun purpose of this study os review and analyze the differences, among clothing terms, between the biblical definitions of the underwear terms and those used by the public in day-to-day life. According, the biblical definitions of the underwear terms which are widely used by the various literature are summarized. Also, the degree of recognition of the underwear terms by the public is studied by analyzing the results of the questionnaires which are distributed to 217 female college students, as the objects of data, who reside in Seoul metropolitan areas. As a result of this study, we find the following conclusions : First, there are considerable differences in definitions of the underwear terms between those used by the various literature and those used by the public. The personal definitions of the underwear terms, or alternatively those used by the public, are very reduced and limited and even misunderstood in some cases. Second, the definitions of the underwear terms which are actually used by the public are recognized mostly by the wearing goals, the wearing spaces, the wearing times, the wearers, the forms and the materials and, among others, the wearing goals are the most dominating factor for the recognition of the underwear terms. Finally, the comparison among the similar underwears reveals that underwears are recognized by the wearing goals, the wearing spaces, the wearers, the forms and the materials. But, the objects of data recognize the underwear terms in very limited and simple fashion instead of having definite recognition of the differences among similar items.

  • Terms of trade is an important indicator of the welfare gains from international trade to the exporting country. Terms of trade of oil-exporting countries are hypothesized to depend primarily on oil prices. The study assesses the relation between oil prices and the terms of trade of Saudi Arabia. The study uses the Autoregressive Distributed Lag method to determine the cointegration between the country's terms of trade and oil prices for the period 2000-2018. The data for net barter terms of trade is taken from World Development Indicators and oil price is taken from Saudi Arabian Monetary Agency. The results show that oil prices and terms of trade are cointegrated and any disequilibrium between the two variables is corrected by 35% in a year. The study also reports a positive relationship between the two items, both in the short run and long run. Diagnostic tests indicate the model to be fit. The results suggest that, for a primarily oil-producing country like Saudi Arabia, the terms of trade depend on oil prices. The study fills the gap in the literature on the study of terms of trade for Saudi Arabia for the last few years, where there has been a high volatility in oil prices.

  • This paper is devoted to the development of the equations which describe the elastic response of a curved laminate subjected to in-plane loads and bending moments. Similar to the classic $6{\times}6$ ABD matrix constitutive relation of a flat laminate, a new $6{\times}6$ matrix constitutive relation between force resultants, moment resultants, mid-plane strains and deformed curvatures for a curved laminate is formulated. This curved lamination theory will provide the fundamental basis for the analyses of curved laminated structures. The stress predictions by the present curved lamination theory are compared to those by the curved laminate analysis that neglected the nonlinear terms in the derivation of the constitutive relation. The results show that the curved laminate analysis that neglected the nonlinear terms cannot reflect the effect of curvature and can no longer predict the stresses accurately as the curvature becomes noticeable. In this paper, a curved lamination theory that retains the nonlinear terms and, therefore, accounts for the effect of the non-flat geometry of the structure will be developed.

  • Purpose - The purpose of this paper is to study how flexibility and mutuality in determining trade terms impact logistics efficiency in the context of relational theory. Additionally, the effect of relational contracts on logistical efficiency relative to the value of the goods being traded is investigated. Design/methodology - According to the relational contract theory, we developed 17 factors utilizing a 7-point Likert scale to measure variables related to flexibility, mutuality, logistics efficiency, and the added value of goods. The survey occurred over four months, and was distributed directly, and via email, phone, and online Google surveys. A total of 403 surveys were collected out of 1,800 distributed, and 380 were analyzed. The principal respondents were import/export companies and members of the Korea International Trade Association and the Korea Small and Medium Business Export-Import Association. The collected data were analyzed using frequency analysis, exploratory factor analysis, and correlation analysis using SPSS ver. 26.0 statistical software, and hypothesis test results were derived using Process Macro ver. 3.5. Findings - This study provides evidence that negotiation flexibility for trade terms affects the efficiency of the logistics process, and the mutuality of such arrangements is shown to be associated with the flexibility and efficiency of logistics processes. Additionally, it has been established that companies whose trade goods possess a low degree of added value may experience increased efficiency in logistics operations if they agree to trade terms that are both flexible and mutually beneficial with their counterparts. Originality/value - This study suggests that in an environment of rapidly shifting global logistics and unpredictable related costs, trade companies may be able to improve logistics efficiency by establishing flexible, mutually beneficial trade terms when entering into contracts. Furthermore, it is suggested that companies dealing in low-value-added products may improve the logistical performance of approaching trade from a perspective of relational contracts.

  • 기술용어 트렌드는 특정 연구 분야의 세부적인 주제가 시간의 흐름에 따라 변화하는 양상을 표현한다. 그런데 학술 문헌이나 특허의 경우에는 그 데이터가 방대하여 인적 자원을 활용하여 트렌드를 분석하는 것이 용이하지 않다. 본 논문은 용어의 활용주기를 모델링하고, 이를 통해 학술 논문에 나타나는 기술용어 트렌드를 탐지하고 분석할 수 있는 방법을 제안한다. 제안된 기법은 다음과 같은 과정으로 구성된다. 먼저 논문 데이터에서 추출된 기술용어를 대상으로 일정 주기별 용어지배값을 측정한다. 용어지배값 획득되면 이를 기반으로 용어 활용주기를 모델링한다. 이 모델링 과정에서 활용주기의 시계열 패턴이 유사한 기술용어들은 동일 트렌드 범주로 분류한다. 본 논문의 기술용어 트렌드 분석 실험을 위해 한국과학기술정보연구원이 운영 중인 국가과학기술정보센터(NDSL) 학술 논문 데이터를 활용하였다.
