The visualization materials in science textbooks are very important in students' learning. Recent visualizations are increasingly emphasizing the importance of infographic visualizations. The purpose of this study is to analyze the visualization materials in $5^{th}$ and $6^{th}$ elementary science textbook focusing on infographics. Visualization materials were classified into infographic and simple illustration. Infographics were classified into 8 sub-types. Findings are as follows. First, infographics were 19.0%, and simple illustrations were 81.0% among elementary textbooks' visualization materials. The portion of infographic varied by content areas. In Biology and Earth Science area, the portions of infographic were high. Second, several types of infographics were used in elementary science textbooks. Timeline infographic were the most frequent, and emphasis infographic, concept mapping infographic, comparison infographic were used frequently. The most frequent types of infographic were different by content area. Third, infographics used more than simple illustrations in the role of concept explanation. Educational implications on science textbook's infographics were discussed.

In this paper, firstly examined various proofs types that cover informal empirical justifications by Balacheff, Miyazaki, and Harel ＆ Sowder and Tall. Using these theoretical frameworks, justification activities by 5th graders were analyzed and several conclusions were drawn as follow: 1) Children in 5th grade could justify using various proofs types and method ranged from external proofs schemes by Harel & Sowder to thought experiment by Balacheff This implies that children in elementary school can justify various mathematical statements of ideas for themselves. To improve children's proving abilities, rich experience for justifying should be provided. 2) Activities that make conjectures from cases then justify should be given to students in order to develop a sense of necessity of formal proof. 3) Children have to understand the meaning and usage of mathematical symbol to advance to formal deductive proofs. 4) New theoretical framework is needed to be established to provide a framework for research on elementary school children's justification activities. Research on proof mainly focused on the type of proof in terms of reasoning and activities involved. But proof types are also influenced by the tasks given. In elementary school, tasks that require physical activities or examples are provided. To develop students'various proof types, tasks that require various justification methods should be provided. 5) Children's justification type were influenced not only by development level but also by the concept they had. 6) Justification activities provide useful situation that assess students'mathematical understanding. 7) Teachers understanding toward role of proof(verification, explanation, communication, discovery, systematization) should be the starting point of proof activities.

동굴 관광자원은 동굴을 방문하는 관광객의 성격 등이 매우 다양한 구성원으로 되어 있으며, 동굴내부의 지형지물에 대한 명칭이나 설명문을 포함한 안내문은 동굴을 찾는 관광객에게 중요한 정보를 전달하는 매체로서의 역할을 하고 있다. 그러나 실제로 동굴지형지물에 대한 명칭 및 안내문에는 많은 오류를 비롯하여 관람객에게 혼동을 주거나 올바르지 않은 정보를 제공하는 결과를 초래하고 있다. 이러한 정보전달의 매체로서의 중요성을 인식하고 그 문제점을 파악하였다. 문제점은 다음과 같다. 1) 대부분 동굴 지형의 학술적 명칭보다는 지형지물의 형태에 따른 추상적인 명칭이 부여되고 있다. 2) 대부분의 지형지물에 대한 명칭만이 부여되어 학술적 설명문이 미약하여 정보 매체로서의 역할이 부족하다. 3) 설명문의 경우, 잘못된 표현이나 오류가 보이며, 학술적으로 논란이 있는 부분을 객관적이지 못한 설명이 되어있다.

This study is to categorize five types of conflict handling styles that employees can take when conflict occurs. The five types are integrating, avoiding, dominating, obliging, and compromising. I found these factors that explain conflicts handling styles divided them into organizational structure, task group functioning and need styles and how certain factors explain different kinds of conflict handling styles without other factors. To measure conflict handling styles, this study used the scale of conflict style devised Rahim. Data were collected by the survey method from employees engaged in the service industry located Seoul, the Province of Gyeonggi, and the Province of Gangwon. In addition, in order to prove my hypothesis, I used hierarchical regression analysis method to find the pure explanation that each factors have without multicollinearity. According to the study's result, in a person's type of needs, if the need for achievement is high, they prefer integrating style. In contrast, if the need for achievement is low, they prefer avoiding style. Also, if the need for affiliation is high, the employees prefer compromising style. But if the need for affiliation is low and the need for dominance is high, the employees favor dominating style. However, in task group functioning, group homogeneity, group cohesiveness, and group goal clarity are high, or the confidence in peers and management is high, the employees prefer obliging style to other conflicts handling styles. As well as if group homogeneity, group cohesiveness, and group goal clarity are high, it was found that they prefer compromising style. Also, if the role conflict that is related to organizational structure is serious, employees prefer obliging style, but they have weakenss in explanation. To sum up these results, if the employees have obliging style that shows lack of concerns over themselves and at the same time, have high concerns to others, is affected by task group or organization. And we can infer that the other conflicts handling styles are effected by personal characteristic.

This study investigated whether and how semantic nature of intransitive verbs can be related to the L2 overpassivization errors. A total of 126 Korean high school students participated in a grammaticality judgment test on English sentences in which seven semantically different types of intransitive verbs were passivized. The results showed that there was an effect of semantic type on the students' judgment on overpassivization errors. Overall, it was shown that the students experienced the lowest degree of difficulty with the Controlled Process-Motional type verbs while experiencing the high degree of difficulty with the Change of State, Existence of State, Continuation of Pre-existing State, and Uncontrolled Process types. Two interlanguage patterns were also identified: the students at higher proficiency level and those at lower-proficiency level showed distinctive patterns on the task. It was argued that the simple dichotomy of unaccusative-unergative distinction does not suffice for the explanation of the complex phenomenon of L2 overpassivization.

In this paper, influence of geometric configurations of multi-story bracing on shear lag behaviour of braced tube structures is investigated. The shear lag of 24-, 36- and 72-story braced tube structures are assessed considering all possible configurations of overall X and Chevron bracing types. Based on the analytical results, empirical equations, useful for the preliminary design phase, are proposed to provide the optimum number of stories that braced, in order to exert minimum shear lag on structures. Studying the interaction behaviour of a tube and different bracing types along with paying attention to the shear lag behaviour, a better explanation about the reasons behind the efficiency of a specific bracing module in decreasing the shear lag is developed. The analytical results show that there are distinct differences between the anatomy of braced tube structures with X and Chevron bracing regarding the shear lag behaviour.
