The goal of mathematics education in the 7-th national curriculum is focused on maximizing learning effectiveness through teaching mathematics, considering learning contents and levels appropriate to various levels of students' abilities. Thus, reduction of contents, learner-centered way of teaching, and multi-step differentiated learning are centered around the curriculum. However, in reality one of the most difficult problems mentioned by many inservice teachers is that students are not interested in school mathematics because some of them tended to learn mathematics in advance in private institutes and others felt difficult from school mathematics. Thus, alternative solutions are strongly required. When students are more interested in mathematics classes and instructional materials, as a more effective way of teaching, are appropriately used, problems mentioned above are expected to be solved. In order to solve problems, additionally, this study investigated the amount of time assigned to each area of mathematics textbooks from level 1-A to level 6-B, which are currently used in elementary school. This study also examined inservice teachers' views about how instructional materials should be used. This will be helpful on using and developing instructional materials, and it will lead to more exciting classes of mathematics. However, these teaching materials need to be carefully used regarding their relationships with pedagogical transfer, metacognitive movement, and localization.

The category killer that has been rapidly growing mainly in advanced countries since early 1990's, is a mew distribution model which aims for obtaining market controlling power by surpassing competing businesses in a specific area of products. The domestic situation of category killers is very different from that of advanced ones abroad since it has just been introduced into the Korean market. At the moment, there are only 10 or so companies operating in the market : Geopyung's , Taeheng's , Midopa's , of Sinsegye Department store, adn of Yerim International. The purpose of this study is to examine problems of domestic companies in the present market by analysing the operation status of category killers in domestic markets as well as foreign ones, and to suggest a counter-strategy of category killers for the distribution environment of the 21st century to improve the competitiveness of Korean distribution industry. The competitiveness of category killers lies above all in products lines. Category killers are equipped with the greatest number of products lines among those of competing businesses due to maximized product selections in an limited range. Another source of competitiveness may be found in balanced strategy positioning. That is to say, category killers are in a position where they can adjust policies towards any of the three purposes while aiming at them altogether : prices of discount stores, products range of specialty stores, and customer service level of department stores. It is also necessary for efficient store operation to use information technology such as electronic data interchange (EDI), electronic pose system(EPOS) and electronic funds transfer (EFTPOS). As for the cost structure, category killers can gain an advantage over other business since operating cost of various sections can be saved. There are, however, certain risks that category killers with strong competitiveness may influence on other businesses a great deal and even facilitate their decline. Yet it seems that the growth of category killers will be more viciously restrained by continuous challenges from other businesses. The distribution industry is supposed to develop through such competition and restraint.

The concept and discussion of copyright should reflect changes in using environments of digital properties and developments of technology. Further discussions are required about protection, transfer and usage of copyright for user created contents or digital activities. Digital archives should clarify the ranges of permitted usage or guides to quotation. One should not be biased toward regulating digital copying, but consider the value of diverse transformation of digital properties. This will trigger tension between private and public usage, or sharing of digital fabrications, which leads to the necessity of discussions on policy level. The interpretation of copyright is limited to protecting the copyright owner's right, but it should be suggested to widen the range to permitting fair use. The extended fair use of digital contents and by clarifying specific rules will activate creation and distribution of digital contents and contribute to more productive usage of innovation.

With the aim of promoting the use of metropolitan railways, the present research developed a mode choice model for evaluating its competitiveness against passenger cars. A case study was carried out with Gyeongeui and Joongang line, and the area of interest was the direct operating railway between Ilsan and Guri station where the two lines intersect. The mode choice model was a disaggregate behavior model which used Stated Preference (SP) survey data, and the plot of competition was between private passenger cars and express trains. As a result, the mode choice model was established, and this model was used to analyze characteristics of passengers' time value and elasticity. It was shown that reducing travel time is more efficient than reducing travel cost when it comes to operating express trains in metropolitan railways. Therefore, policies designed for activating the use of metropolitan railways should expand direct operating service of individual lines and run more express trains in order to minimize transfer and in-vehicle time.

The purpose of this study is to analyze the influences on resource transfers between middle-aged parents and their married children. This study used 2009 data from the National Research Foundation of Korea regarding inter-generational resource transfers and preparation for later life (kfr-2009-c00010). A sample of 1208 households of middle-aged parents with married children was used. The study found that parents provided financial resource transfers to their married children in the following circumstances: where parents received financial resource transfers from their married children, where the household income of parents was high, where the children were younger, and where the children were male. Parents provided instrumental resource transfers to their married children in the following circumstances: where parents received instrumental resource transfers from their married children, where the gender of children was female, where the children were employed, where married children had their own children who were either younger than a preschooler, and where household incomes of married children were high. Parents received financial resource transfers from their married children in these circumstances: where their emotional ties with their children was high, where the household income of the parents was low, where the household income of the married children was high, and where married children had preschoolers. The circumstances in which parents received instrumental resource transfers from their married children were where parents provided instrumental resource transfers and the household incomes of married children were high.

The purpose of this study is to investigate the economic deprivation of male-headed or female-headed households. Household having children under the age of 18 are categorized into three types according to the gender of household head: male-headed household, female-headed household, and dual-parents household. The findings from data, for this study came from the Korean Labor Panel Study in 2003. The analysis shows that the household's age, education, residence types, etc are key explanatory variables in determining whether to be in poverty. While the public income transfer is most effective in reducing poverty in female-headed households, the private income source is relatively more useful among male-headed families. Since single-household families are particularly at risk, public policy makers should pay special attentions to developing and expanding welfare-to-work programs which provides work incentives to overcome relative poverty and community networks on child care.

TMN(Telecommunication Management Network) provides underlying structure to transfer, store and processing management information which are necessary for Telecommunication network and service management. The application of TMN is widely applicable to Analogue telecommunication network Public and private network switching system, Transmission system, Telecommunication related software and logical telecommunication network resource management and others. This paper consider TMN as one System Under Test(SW), and propose a new TMN test architecture, besides existing simulation based test method, which is able to test, on the basis of standardized testing procedure and testing method, directly with test system. There are several fields in protocol testing and one of them is protocol conformance testing which is defined in ISO/IEC 9646 series and it has twin document as ITU X.290 series. To apply this standardized procedure on TMN testing it is prerequisite to devise a new TMN testing architecture and set up testing procedures according to the new architecture.
