Recently, in accordance with the development of IT technology, it is prevalent for power quality monitors to be connected to each other via networks and share their data because such networks provide system-wide insights to customers concerning power quality. Those systems can alarm and display power quality events for the convenience of customers. However, if a power quality event occurs, it is difficult for customers to determine its cause and solution because the systems do not provide appropriate power quality diagnosis functions. The power quality management system presented in this paper has been developed to provide customers with various power quality diagnosis functions so that they can cope well with power quality problems with the right measure in the right place. This paper presents the structure and functions of the developed power quality management system and shows some results of the power diagnosis functions.

IZO transistors with $Al_2O_3$ as gate dielectrics have been investigated. To improve permittivity in an ambient dielectric layer, we grew $Al_2O_3$ by atomic layer deposition directly onto the substrates. Then, we prepared IZO semiconductor solutions with 0.1 M indium nitrate hydrate [$In(NO_3)_3{\cdot}xH_2O$] and 0.1 M zinc acetate dehydrate [$Zn(CH_3COO)_2{\cdot}2H_2O$] as precursor solutions; the IZO solution made with a molar ratio of 7:3 was then prepared. It has been found that these oxide transistors exhibit low operating voltage, good turn-on voltage, and an average field-effect mobility of $0.90cm^2/Vs$ in ambient conditions. Studies of low-voltage driving of IZO transistors with atomic layer-deposited high-k $Al_2O_3$ as gate dielectric provide data of relevance for the potential use of these materials and this technology in transparent display devices and displays.

The purpose of this study was to investigate the effects of sociocultural attitudes toward appearance on male consumers' apparel buying behavior and appearance management behavior. The subjects were 353 males aged from 40 to 59 years old. The research method was a survey and the questionnaire consisted of sociocultural attitude toward appearance items, apparel buying behaviors items, appearance management behaviors items, and subjects' demographic characteristics items. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, multiple response analysis, ${\chi}2$ test, ANOVA and Duncan's multiple range test. The results were as follows. Three dimensions (appearance importance awareness, slimness importance awareness, internalization) were emerged on sociocultural attitude toward appearance, and subjects were divided into 4 groups(receptive, unreceptive, awareness, and internalized group) by this variable. The 4 groups by sociocultural attitude toward appearance showed many differences on apparel buying behaviors and appearance management behaviors. Receptive and internalized group more importantly regarded fashion trend and store display as apparel buying motives, design and trend as selection criteria, and did shopping to buy clothes more often than awareness and unreceptive group. Receptive and internalized group recognized higher the need for various appearance management behaviors and spent more expense to enhance their appearance than other groups.

In this paper, linear octree is used to reconstruct and to modify the 3-dimensional image from 2-dimensional cross sections provided by computed tomography. Linear octree introduces a considerable data saving of the memory storage required by small computer system. This structure allows the hidden surface removal utilizing the spatial presortedness of hierarchical octree structure and implementation of graphical operations that include viewing transform and shading. An actual human organ is used to illustrate this technique and its implications for theraphy and surgical planning.

While aromatic polyimides and polyamides have found widespread use as high performance polymers, the present work addressed the need for organosoluble materials through the use of a hyperbranching scheme. The $AB_2$ monomers were prepared. The $AB_2$ monomers were then polymerized via aromatic fluoride-displacement and Yamazaki reactions to afford the corresponding hydroxyl-terminated hyperbranched polyimides (HT-PAEKI) and amine-terminated hyperbranched polyamides, respectively. HT-FAEKI was then functionalized with allyl and propargyl bromides as well as epichlorohydrin to afford allyl-terminated AT-PAEKI, propargyl-terminated PT-PAEKI, and epoxy (glycidyl)-terminated ET-PAEKI, in that order. All hyperbranched poly(ether-ketone-imide)s were soluble in common organic solvents. AT-PAEKI was blended with a bisphenol-A-based bismaleimide (BFA-BMI) in various weight ratios. Thermal, rheological, and mechanical properties of these blend systems were evaluated. Two characteristic hyperbranched polyamides, which the one has para-electron donating groups to the surface amine groups and the other has para-electron withdrawing groups to the surface amine groups, were selected to compare BMI curing behaviors. The electron rich polymer displayed ordinary Michael addition type exothermic reaction, while electron deficient polymer did display unusual curing behaviors. Based on analytical data, the later system provided the strong evidences to support room temperature curing of BMI by reactive intermediates instead of reactive primary amine groups on the macromolecule surface.

The purpose of this study is to figure out the actual situation of possession and use of traditional living appliances in the rural area, so as to provide plans for preservation and succession of traditional living appliances. The data were collected from 200 households in 8 rural areas classified by geographical zone. Traditional living appliances were divided into clothing.food.housing living appliances, play tools, and the others. As a result, the degree of using the traditional living appliances is 46.5%(in respect of "often use"). The need for preserving and using the traditional living appliances in modern society was 68.5%(in respect of "a little need"). The level of preservation and use of the traditional living appliances was relatively low except for food living appliances. In conclusion, the suggested directions for developing traditional goods to preserve and succeed traditional living appliances are as follows; ${\circled1}$ Developing traditional living goods peculiar to a certain locality ${\circled2}$ Developing goods with various uses; display, ornament, living appliances, memorial, etc. ${\circled3}$ Developing goods on the process and technique of making traditional living appliances. ${\circled4}$ Providing information and education on excellance of traditional living appliances.

The exploration of genes which expressions are changed by exposure to ecotoxicants or pollutants can provide the important information about the reaction mechanisms in the body as well as adaptation to exterior stimulus or environmental changes. Also they can be developed as biomarkers for the detection of environmental pollution. Differential display polymerase chain reaction (DD-PCR) technique has been usefully used to hunt the clones which expressions are up-regulated or down-regulated by exterior changes and this study aimed to search for those clones in diesel oil-exposed rockfish (Sebastes schlegeli) using DD-PCR. The RNA isolated from liver of 20 ppb diesel oil-exposed rockfish was used for screening of the differentially displayed genes and total 44 differentially expressed genes (DEG) are detected then their nucleotide sequences were analyzed. The present data provided the general information about the effect of diesel oil contamination on marine organism and further more the primary step in development of new biomarkers for marine environmental pollution or ecotoxicological stresses.

Using differential display techniques, a new acidic pathogenesis-related (PR) protein-1 cDNA (GMPRla) gene was isolated from a cDNA library of soybean (Glycinemax L.Merr, cultivar Jangyup) hypocotyls infected by Phytophthora sojae f. sp. glycines. The 741 bp of fulllength GMPRla clone contains an open reading frame of 525 nucleotides encoding 174 amino acid residues (pI 4.23) with a putative signal peptide of 27 amino acids in the N-terminus. Predicted molecular weight of the protein is 18,767 Da. The deduced amino acid sequence of GMPRla has a high level of identity with PR-1 proteins from Brassica napus, Nicotiana tabacum, and Sambucus nigra. The GMPRla mRNA was more strongly expressed in the incompatible than the compatible interaction. The transcript accumulation was induced in the soybbean hypocotyls by treatment with ethephon or DL-$\beta$-amino-n-butyric acid, but not by wounding. In situ hybridization data showed that GMPRIa mRNAs were usually localized in the vascular bundle of hypocotyl tissues, especially phloem tissue. Differences between compatible and incompatible interactions in the timing of GMPRla mRNA accumulation were remarkable, but the spatial distribution of GMPRla mRNA was similar in both interactions. However, more GMPRla mRNA was accumulated in soybean hypocotyls at 6 and 24 h after inoculation.

The purpose of this study is to (1) investigate on the impulse purchase tendency of women who buy women's character clothing brands and (2) to clarify the relationship between the women's impulse purchase tendency and the marketing factors, and the brand image. The subjects were 203 women in their twenties and thirties who had purchased the women's character clothing brands in last six months living in Seoul. The data were collected by self-administered questionnaire and were analyzed by frequency, percentage, t-test, clustering analysis and MDS(Multi-Dimensional Scale). The results of the study were as follows: (1)66.0% of the women were categorized as the group of high-degree of impulse purchase tendency and 34.0% of the women were identified as the group of low-degree of impulse purchase tendency. (2) In identifying the relationship between the marketing factors and the impulse purchase tendency, the group of the high-degree of impulse purchase tendency was affected by the marketing factors such as new and fashionable products, status of display, advertising and discout selling. (3) Brand image was not statistically significant according to the impulse purchase tendency. As a whole, 'Obzee' was recognized as unique-style and sexy brand, 'Time' and 'Mine' were thought as the reasonable-prince and basic-style brands, 'Deco' were clarified as the intellectual-image brand, and 'Ego' and 'Telegraph' were revealed as high-price-image brands.
