A poor achievement of basic competency leads to obstacles of the same subject and other subjects from a series of accumulative losses and social life. The Grade 3 National Diagnostic Assessment of Basic Competency (NDAHC) dated from 2002, Teaching Plan Responsible to Basic Competency and compensational education materials for students of the below-basic level has marked a line in the chain of policy to realize educational welfare. The goal of NDABC is to collect information of the reason with regard to learning deficiency and individual student's information, and ultimately teach them on the basis of those informations. This study analyzed the characteristics of below-basic students in the basic mathematics with data from NDABC from 2003 to 2007. Students of the below-basic level were affected in achievement by numerical distinction, regrouping, arrangement and descriptive form of item, information-providing way, typical example, familiarity, frequency in use in daily life etc. This study provides a basic important information with regard to teaching below-basic students and suggestions with compensational education materials for them.

New spiro-type host materials, 5'-phenylnaphthyl-spiro[fluorene-7,9'-benzofluorene](BH-lPN) and 5',6-bis(phenylnaphthyl)-spiro[fluorene-7,9'-benzofluorene](BH-6PN) were designed and successfully prepared by the Suzki reaction. The EL characteristics of BH-1PN as blue host material doped with blue dopant materials, BD-1 were evaluated and compared with the existing host MADN:dopant BD-1 system. The structure of the device is ITO/DNTPD/NPB/Host:5% dopant/Alq3/Al-LiF. The device obtained from BH-lPN doped with BD-1 showed a good color purity and efficiency, on the other hand luminance and current-density characteristics are worse than that of MADN doped with BD-1.

This study focused on the development of creative materials by applying tapestry to produce original and high-grade dresses with consideration the modems' tendency to place high value on personal taste and style. The development remained sensitive to current trends and attempted to expand into high value-added dresses. Materials in modem fashion design, as a basis of the fashion industry, can lead to a current of new fashion and produce novel and creative ideas by stimulating the designers' creativity. Designers can diversely express a form according to their intention, since tapestry allows the expression of various feelings of texture and forms according to the combination mode of technique, structure and materials on a basic plane. Moreover, tapestry encrourages the development of varied designs because it can effectively display the texture and color of a textile surface through the careful selection of materials even under the same technique. Tapestry can apply forms similar to a textile's basic structure to fashion design and can create high added value with the merit of being 'handmade'.

[ $HfO_2$ ] and $HfO_xN_y$ films were deposited by plasma-enhanced chemical vapor deposition using $Hf[OC(CH_3)_3]_4$ as the precursor in the absence of $O_2$. The crystallization temperature of the $HfO_xN_y$ films is higher than that of the $HfO_2$ film. Nitrogen incorporation in $HfO_xN_y$ was confirmed by auger electron spectroscopy analysis. After post deposition annealing (PDA) at 800$\Box$, the EOT increased from 1.34 to 1.6 nm in the $HfO_2$ thin films, whereas the increase of EOT was suppressed to less than 0.02 nm in the $HfO_xN_y$. The leakage current density decreased from 0.18 to 0.012 $A/cm^2$ with increasing PDA temperature in the $HfO_2$ films. But the leakage current density of $HfO_xN_y$ does not vary with increasing PDA temperature because an amorphous $HfO_xN_y$ films suppresses the diffusion of oxygen through the gate dielectric.

Following the PART I, which explored the concept of ＇Fashion Goods＇ and ＇Basic Goods＇ in terms of design elements and operational differences, this study, PART II, examined the differences in merchandising process of the two different types of goods. Merchandising process was divided into three stages; planning, production, and presentation. The study adopted a qualitative approach by use of eighteen in-depth interviews with merchandisers and designers with a minimum of six years and a maximum of 15 years of career experience in apparel industry. According to the type of goods, different merchandising practices were found. Especially material and production order/reorder practices were noteworthy. Fashion goods had high possibility of using high-quality materials sourced abroad and few of them were reordered. In other words, reorder practices were established for basic goods only; replenishment was actively implemented for higher inventory turn of basic goods; usually materials and production for basic goods were sourced domestically. In conclusion, based on the differences, more refined merchandising strategies of apparel companies and consistent theory building in this field are required for fashion and basic goods respectively.

In these days, as building structures are getting taller, larger, and more diversified, structural systems with more economy and more efficiency are being required and so are more efficient building materials, this study conducted a basic experiment to conclude an adequate selection of materials and to calculate an optimal mixing proportion of those materials to produce High-strength concrete in a 100MPa of specified concrete strength. And also we conducted an experiment to find out basic properties of this concrete such as slump-flow, strength.
