The Korea-Canada FTA and the EVTA have adopted cross-cumulation clauses in their rules of origin, aiming at the enhancement of the value chains among the FTA parties. In fact, intricate rules of origin are often considered as the major cause that discourages the utilization of the agreement for the exporting firms. From this perspective, the correct understanding of cross-cumulation clauses in FTAs is an urgent mission for the Korean exporters as well, and the EVTA, which has recently introduced the cross-cumulation method in a linkage with the Korea-EU FTA provides the timely motivation. This paper first analyzes the Korea-Canada FTA of 2015 as for the case study, because this is a unique trade agreement for Korea that has already adopted the cross-cumulation clauses. It is concluded that the clause is rather vague, particularly in certifying the origins of the intermediate goods from the territory of an authorized third party. From this perspective, the recently-ratified EVTA is particularly important and meaningful with its clearer explanations for the utilization of the privileged rules of origin. The paper finalizes the study by making policy suggestions to the stakeholders, expecting more future FTAs to come equipped with similar cumulative rules of origin, and implies the possibility of the modification of the current clauses in the FTA with Canada.

This study analyzed the types of scientific humors made by scientifically-gifted elementary school students and their perceptions of making scientific humor. For this, 77 students from $4^{th}$ to $6^{th}$ graders of gifted science education center in Seoul National University of Education were selected. Scientific humors made by the students were analyzed according to the number and types. Their perceptions of making scientific humor were also analyzed through a questionnaire and group interviews. The analysis of the results revealed that most of scientifically-gifted students made more than 2 scientific humors, and the number of scientific humor for each students varied from 0 to 11. The most types they made were the descriptive type and the pun using pronunciation type, but they made various types without any special type to be biased. And They made more the dialogue type than the narrative type, especially the riddle type. They used scientific knowledge that preceded the knowledge of science curriculum in their grade level over two or more years. The scientific knowledge of chemistry was used more than physics, biology, earth science and combination field. The name utilization type was more than the characteristic utilization type and the principle utilization type. Scientific humors in the everyday situation were more than humors in artificial situation. The students had various positive perceptions in making scientific humor such as increase of scientific knowledge, increase of various thinking abilities, deep understanding of science concept and principle, increase of interest and motivation about science and science learning, and increase on sense of humor. They had also some negative perceptions related to difficulties in the process of making scientific humor, lack of fun, and lack of time in the class.

This study develops and validates an objective scale to measure newspaper use at home by elementary school students and parents. We developed a preliminary scale of 59 items through the review of literature on newspaper use and mediation as well as the examination of content validity by education experts. Collected data were analyzed using SPSS 21.0 and AMOS 21.0 programs. A total of 42 items were supported by 703 parents with students in grades 1-6 using exploratory factor analysis. The model included 3 categories and 9 sub-factors: instruction (modeling, restriction, and text instruction), activities (play activity, conversation, online mediation, and scrap activity), and belief (academic achievement and information acquisition). Confirmatory factor analysis confirmed and validated the model fit; in addition, convergent validity, and discriminant validity, and cross validity was confirmed through correlation analysis by gender comparison and grade comparison. We also verified the validity of this scale through correlation analysis based on Yu and Jung (2012)'s newspaper mediation variables and scale in regards to children's motivation for using newspapers. Finally, internal consistency reliability and half reliability were also confirmed. In conclusion, the suitability and stability of home newspaper utilization scale for elementary students (HNUS-E) were confirmed. This scale provides parents and educators with ideas for the development of the children's literacy, cognitive, and affective domains that can be effectively used in research on newspaper use for school-aged children.

The study investigated computer literacy skills as a determinant of electronic reference sources utilization among selected secondary school students in Ado-Odo Ota Local Government, Ogun State, Nigeria. Four specific objectives with conforming research questions guided the study. Descriptive survey research design was adopted for the study. The population of the study comprises of SSS3 students of the three selected Community Secondary Schools in Ado Odo Ota. A sample size of 150 was used for the study. The instrument for data collection was a self-developed structured questionnaire. Data collected was analyzed using frequency and percentages. Findings of the study revealed that majority of secondary school students were not aware of the availability of electronic reference sources. It also revealed that the level of their computer literacy skills was below average. Majority of them have never used computer before and the few of them that have used computer before used it in their homes, their friend's homes or in the cyber café. It was found that lack of formal training on the use of electronic reference sources, lack of access to computer, lack of awareness of availability of electronic reference sources, lack of funds for internet subscriptions, over dependency on printed reference sources and lack of motivation to use electronic reference sources were the major hindrances to the use of electronic reference sources among secondary school students. It was recommended that the school librarians and teachers should play a role in creating awareness among secondary school students about the availability of online/ electronic reference sources among others.

As the e-marketplace becomes the core of management activities, researches on motivation, transaction type, strategy, satisfaction, risk management, performance evaluation, etc. have been actively studied, but the factors influencing actual utilization have not been fully. Especially, the factors that affect the intention of the users are limited without consideration of internal environment, external environment, e-marketplace characteristics such as operating rules, characteristics of the company to be used. In order to derive the determinants of B2B e-marketplace use, this study was conducted to examine the relationship between internal environment, external environment, e-marketplace characteristics as independent variables, intention of use as dependent variable, participation qualification, The results were as follows. First, the previous study limited the determinants of intention to use to either internal or external, but this study presented an integrated model that considers both factors. Second, the characteristics of companies participating in e-marketplace were identified by using participation qualification and activity scope as control variables.

The constructivism is an important stream of the recent trends of mathematics education. In order for students to construct their knowledge for themselves, above all, it should be a prerequisite that they participate in actively, Using games helps students to participate in learning mathematics actively. I think, up to now, mathematics teachers use games mainly for motivation and it does not connect to true learning mathematics through using games. So, the purposes of this study are developing the mathematical games connecting to mathematical contents closely, designing the teaching models to connect game activities to learning mathematics, and developing several teaching plans using games to mathematics class. In this study, I propose what conditions 'good' game should have, classify games as practice game, concept learning game, and strategy game, and develop 43 games from 1 to 6 grade. And I design the teaching models depending on the game types and develop the teaching plans.

The application of Wireless Sensor Networks requires a wise utilization of limited energy resources. Therefore, a wide range of routing protocols with a motivation to prolong the lifetime of a network has been proposed in recent years. Hierarchical clustering based protocols have become an object of a large number of studies that aim to efficiently utilize the limited energy of network components. In this paper, the effect of mismatch in parameter estimation is discussed to evaluate the robustness of a distanced based algorithm called distributed clustering protocol in homogeneous and heterogeneous environment. For quantitative analysis, performance simulations for this protocol are carried out in terms of the network lifetime which is the main criteria of efficiency for the energy limited system.
