The primary purpose of this study was to investigate how sixth grade elementary school students react to the types of letters use, what levels of understanding letters students are in and what difficulties are in understanding letters, and to raise issues about instructional methods of algebra. A descriptive study through pencil-and- paper tests was conducted. The test instruments consisted of 18 questions with 6 types of letters use. According to the results of testing, students' types of letter use and the levels of understanding letters were classified. The conclusions from the results of this study were as follows: First, the higher the types of letters use, the more sixth grade elementary school students had low scores on the types. Therefore, teaching methodologies of letters and expressions in the classroom need to encourage for students to improve their ability of using and understanding letter. Second, approximately 40% of students were categorized in level 3. Accordingly it is necessary to have a program of teaching and learning to improve their understanding levels of letters. Third, approximately 15% of students were categorized in level 0. In order to develop understanding of letters, it is important that students use letter evaluated and letter used as an object. Fourth, students had the difficulties in understanding letters. It is informative for teachers to understand these students' difficulties and thinking processes. Finally, we must treat the different uses of letters and introduce them successively according to the student's understanding levels of letters.

Deferred payment letter of credit is the L/C that makes the issuing bank to pay a beneficiary at maturity stipulated in the credit. In this deferred payment letter of credit transaction, is it possible that a confirming or nominating bank payor negotiate before maturity? and the confirming or nominating bank have legal protection when paid or negotiated before maturity? These problems are raised in argument. By the way, Korea, Switzerland, Germany, and Italy are positive on the above question, but France, United Kingdom, and Singapore are negative. Therefore, when using deferred payment letter of credit, it is required to keep in mind that the understanding of maturity stipulated in the credit is different among countries, legal principles of each nations, and researchers. And other problems are raised also as follows; the application of Fraud Rule and principle of independence and abstraction as nature of credit, when to pay credit amount to beneficiary, and refusal of payment due to poor quality. Finally, it is required to use deferred payment letter of credit, after full understanding of deferred payment letter of credit pointed out in this paper.

Effectiveness of information conveyance in reading is affected by several factors such as line length, letter size, line spacing arrangement as well as typeface itself. This study examined relative importance of these factors by asking people to read the texts that was constituted with non-square form letter and rank the preference of texts through conjoint analysis. In the case of reading time, justification was the most important factor, followed by leading, line spacing, letter width, line length, font size, font type in their order of importance. And in the case of preference decision, letter width was the most important factor, followed by font size, justification, line spacing, leading, line length, font type. The result will be useful in understanding how to consider human preference in the hangul typography.

This thesis intends to grasp the degree of utilization of visual images by understanding the relational properties between picture and letter and considering the children as users, through the analysis of currently published books of English vocabulary for children. Accordingly, the types of picture used in the books of English vocabulary for children, the degree of utilization of picture, combination types of picture and letter, and semantic consistency of picture and letter are reviewed. As a result of analysis, the degree of utilization of picture is high in general, in order of illustration, cartoon, and the mix of illustration and cartoon. In the combination form of picture and letter, the degree of utilization appears in order of picture plus vocabulary, letters without illustration, and pictorial symbol. In particular, the higher semantic consistency of picture and letter, it is effective in learning, however, semantic consistency is low, generally. Pictorial symbol type shows the frequency of the highest combination type in the five groups of higher semantic consistency. In conclusion, the presented types of picture and letter, shown in the currently published books of English vocabulary for children, are similar types by the publishing companies, thus, effective design research should be required based on diverse levels of children.

Studying the definition and building a foundation about variables during elementary school is a crucial factor before students study the variable in depth in middle school. So, forming a basis for understanding variable in this period should be treated with importance, because it is the first step in forming a clear understanding of the concept of variables. According to analysis of the types of letters used in current textbooks, we can see that too much emphasis was placed on type 1(letter evaluated), type 3(letter used as an Object). By not utilizing the various types of letter usage we reduce the situation to one which is removed from the context and an automatous style of learning. Therefore, the purpose of this study was the development about early algebra learning materials which use diverse types of letters. We have analyzed the types of letters used from the 4-ga to 6-na mathematics textbooks and the 4-ga to the 6-na workbooks. To make learning materials for well-balanced letter use, we developed learning materials focused on early algebra with the 6-ga and the 6-na textbooks.

This study examined relative importance of these factors by asking people to read the texts that was constituted with square and non-squre form letter and rank the preference of texts through conjoint analysis. In the case of reading time, font type was the most important factor, followed by leading , line width, font size, line length, justification, letter width in their order of impotance. And in the case of preference decision, font size was the most important factor, followed by font type, leading, line width, letter width, justification, line length. The result will be useful in understanding how to consider human preference in the Hangul typography.

This paper intends to study some problems in the application of UCP 600 in the international trade transactions with China. Generally speaking, China complies with UCP 600 well. Nevertheless, there are some problems in the application of UCP 600 in China owing to the difference in law and practices. There are some problems in the application of UCP 600 in China owing to the difference of practices under Bills of Exchange Act and The Provisions of the Supreme People's Court on Some Issues Concerning the Trial of Cases of Disputes over Letter of Credit. The Act insists on the formal requirements, the consistency between a letter amount and a figure amount, the unconditional payment character of bills of exchange. The Provisions include the recognition of revocable credits, the difference of standard in examining documents, the difference in the treatment of issuing banks in relation to discrepant documents. These aforesaid matters of the Act and the Provisions are inconsistent with the practices under the UCP 600. There are two main problems in the operation of letters of credit in China. One is the lack of concerned parties' practice knowledge in relation to letters of credit in China. The other is the inactive stance of nominated banks in China. There are two main problems in relation to judiciary institutions in China. First, judges in China tend to abuse the injunctions owing to the lack of understanding in relation to letters of credit. Secondly, there are inconsistency in the court ruling in China.

Recent research suggests that the brain has capable of remarkable plasticity and physical activity can enhance it. In this editorial letter, we summarize the role of hippocampal plasticity in brain functions. Furthermore, we briefly sketched the factors and mechanisms of motion that influence brain plasticity. We conclude that physical activity can be an encouraging intervention for brain restoration through neuronal plasticity. At the same time, we suggest that a mechanistic understanding of the beneficial effects of exercise should be accompanied in future studies.

This project examined 2, 3, and 4-year-old children (N = 34) in a university campus child care setting to assess their understanding of the graphic features they use in their emergent writing (to distinguish it from a drawing of the same referent). The graphic features present in samples of the children's work were examined and compared to the graphic features children could identify through verbal and nonverbal communication. We examined the frequencies of graphic feature identification, as well as significant differences between graphic feature usage and graphic feature identification. The most frequently used graphic features were linearity, unidirectionality, and small size of units. The most frequently identified graphic feature was conventional letter. Overall, children used significantly more graphic features than they were able to identify. Significant relationships comparing the 2-year-old group and 4-year-old group's usage and identification were also found. The findings are discussed in terms of their application to early childhood classrooms. Teachers can apply these findings when engaging children in conversations about their emergent writing; these discussions are explored as a beneficial teaching tool.
