  • Metadata and ontology can be used to retrieve related information through the inference mure accurately and simply on the Semantic Web. RDF and RDF Schema are general languages for representing metadata and ontology. An enormous number of keywords on the Semantic Web are very important to make practical applications of the Semantic Web because most users prefer to search with keywords. In this paper, we consider a resource as a unit of query results. And we classily queries with keyword conditions into three patterns and propose indexing techniques for keyword-search considering both metadata and ontology. Our index maintains resources that contain keywords indirectly using conceptual relationships between resources as well as resources that contain keywords directly. So, if user wants to search resources that contain a certain keyword, all resources are retrieved using our keyword index. We propose a structure of table for storing RDF Schema information that is labeled using some simple methods.

  • Integrin-linked kinase 1 (ILK1) regulates several protein kinases, including PKB/Akt kinase and glycogen synthase kinase ${\beta}$. ILK1 is also involved distinctively in the cell morphological and structural functions by interacting with the components of the extracellular matrix or integrin. According to the information of serum- and glucocorticoid-induced kinase 1 (SGK1) substrate specificity (R-X-R-X-X(S/T)-${\phi};{\phi}$ indicates a hydrophobic amino acid), two putative phosphorylation sites, $Thr^{181}\;and\;Ser^{246}$, were found in ILK1. We showed that ILK1 fusion protein and two fluorescein-labeled ILK1 peptides, $FITC-^{174}RTRPRNGTLN^{183}$ and $FITC-^{239}CPRLRIFSHP^{248}$, were phosphorylated by SGK1 in vitro. We also identified that 14-3-3 ${\theta}\;{\varepsilon}\;and\;{\xi}$, among several 143-3 isotypes $({\beta},\;{\gamma},\;{\varepsilon},\;{\eta},\;{\sigma},\;{\theta},\;{\tau}\;and\;{\xi})$ formed protein complex with ILK1 in COS-1 cells. Furthermore, the phosphorylation of $Ser^{246}$ by SGK1 induced the binding with 14-3-3. It was also demonstrated that 14-3-3-bound ILK1 has reduced kinase activity. Thus, these data suggest that SGK1 phosphorylates $Thr^{181}\;and\;Ser^{246}$ of ILK1 and the phosphorylation of its $Ser^{246}$ makes ILK1 bind to 14-3-3, resulting in the inhibition of ILK1 kinase activity.

  • The purposes of this studs were 1) to identify web navigation values and classify consumers based on these values and 2) to determine differences between consumer groups and between types of shopping mall in evaluation of website attributes when shopping apparel. The data were collected via a self-administered questionnaire from 204 male and female students who experienced shopping at the website, living in Cheju and analyzed by factor analysis, cluster analysis and t-test. Two factors of navigation value were found and labeled as; information value and entertainment value. Two groups were identified based on navigation value; users of information value (53%) and users of entertainment value (47%). Significant differences between two groups were found in evaluating website attributes selling products of various types regarding apparel products and processes for information search, order and payment. However, for shopping mall website selling only apparel products, differences between two groups were not significant in evaluating most attributes except for two items to evaluate apparel products. Differences between shopping mall types (shopping malls selling products of various types and selling only apparel product) were significant in evaluation of internet users of information value regarding attributes of apparel products while differences between shopping mall types were not significant in evaluation of users of entertainment value regarding all attributes. Internet users of information value showed favor to shopping mall website of department store type chi e internet users of entertainment value showed favor to shopping mall website selling only apparel products.

  • Menswear body types are often labeled on garments (to indicate how the garments are designed to fit) with indicators of a size category such as regular, portly, and stout, athletic, or big and tall. A drop (relationships between the chest and waist girths) is related to the fit of a tailored suit. However, current standards are not designed for various drops or body types. There is not enough information of categorizing men's body shapes for the apparel sizing systems. In this article, a set of men's data from SizeUSA sizing survey was analyzed to investigate men's body shapes and drops. Factor analysis and a cluster analysis method were used to categorize men's body shapes. In the results, twenty-five variables were selected through the factor analysis and found four factors: girth factor, height factor, torso girth factor, and slope degree factor. According to the factor and cluster analysis, various body shapes were found: Slim Shape (SS - tall ectomorphy), Heavy Shape (HS - athletic, big & tall, endomorphy and mesomorphy), Slant Inverted Triangle Shape (SITS - regular, slight ectomorphy and slight mesomorphy weight range from normal to slightly overweight), Short Round Top Shape (SRTS - portly and stout, endomorphy). Body shapes were related to fitting categories. SS and HS were related to big & tall fitting category. SITS was related to regular. SRTS was related to portly and stout. Shape 1 (31%) and Shape 2 (26%) were related to current big & tall category. Shape 3 (34%) were related to regular. Shape 4 (9%) were in portly and stout category. ASTM D 6240 standard was the only available standard that presented a regular fitting category. Various drops were found within a same chest size group; however, this study revealed great variances of drops by body shape.

  • The purpose of this study was to isolate a specific DNA probe for the strain ATTC 25611 of the species Prevotella intermedia by using a new rapid screening mothod. The whole-genomic DNA of P. intermedia ATCC 25611 was isolated and purified. The HindIII-digested genomic DNAs from the strain were cloned by the random cloning method. To screen the strain-specific DNA probe, inverted dot blot hybridization tests were performed. In this assay, 20 ng of recombinant plasmids containing the HindIII-digested genomic DNA fragment were boiled and blotted onto a nylon membrane, and hybridized with digoxigenin-dUTP labeled genomic DNAs in a concentration of 100 ng/ml. Southern blot analysis was performed in order to confirm the results of the inverted dot blot hybridization tests. The data showed that a Pi34 probe (2.1 kbp; 1 out of 32 probes) was specific for P. intermedia strain ATCC 25611 and could be useful for the detection and identification of the strain, particularly in epidemiological studies of periodontal disease.

  • We propose a method of selecting initial training examples for active learning so that it can reach high accuracy faster with fewer further queries. Our method is based on the assumption that an active learner can reach higher performance when given an initial training set consisting of diverse and typical examples rather than similar and special ones. To obtain a good initial training set, we first cluster examples by using k-means clustering algorithm to find groups of similar examples. Then, a representative example, which is the closest example to the cluster's centroid, is selected from each cluster. After these representative examples are labeled by querying to the user for their categories, they can be used as initial training examples. We also suggest a method of using the centroids as initial training examples by labeling them with categories of corresponding representative examples. Experiments with various text data sets have shown that the active learner starting from the initial training set selected by our method reaches higher accuracy faster than that starting from randomly generated initial training set.

  • This study was conducted to investigate the effects of black raspberry wine, administered per os on testosterone levels in rabbits. Black raspberry wine containing 13% alcohol(v/v) was prepared from ripe fruits of Rubus coreanus fermented with Saccharomyces cervisiae. Experimental rats were divided into 2 groups(A and B) with 2 animals group: Group A received black raspberry wine. Group B received 13% concentrated alcohol('Soju') over a period of 6 weeks. all animals were monitored weekly for testosterone levels by radioimmunoassay using $^{125}I$ labeled anti-testosterone monospecific antibody. There was a significant(1.7-2.33 fold) increase in testosterone levels in Group A with a peak at 1 week post administration of black raspberry wine. There was no significant change in testosterone levels of rabbits in Group B. These data point to yet uncharacterized phytotestronegenic mechanisms of black raspberry wine that appear to be independent of ethyl alcohol. Further investigation of the mechanism of action of this fruit is warranted. These observations have potential implications for human reproductive health.

  • Data are limited on the association between dietary patterns and screen time among Korean adolescents. The present study identified dietary patterns of 691 adolescents, aged 13-18 years, who had participated in the Third Korean National Health and Nutrition Examination Survey (KNHANES III) and analyzed their associations with screen time. Screen time was defined as the time spent watching TV, using a computer, or playing video games was calculated as a sum of all these times. Dietary patterns and their factor scores were derived from a food frequency questionnaire using the factor analysis method. To analyze the association between dietary patterns and screen time, we conducted multiple linear regression analysis. We also performed multiple logistic regression analysis to estimate odds ratios (OR) of excessive screen time (2 hours or longer per day) and 95% confidence intervals (CI). We identified 2 dietary patterns labeled "the Korean healthy dietary pattern" and "the Western diet and fast foods pattern". The former included mixed grains, legumes, potatoes, red meat, eggs, fish, dairy products, fruits, vegetables, seaweeds, and mushrooms, whereas the latter included noodles, bread, red meat, poultry, fast foods, snack, and soft drinks. After controlling for potential confounding factors, factor scores for the Korean healthy dietary pattern were inversely associated (P-value for trend < 0.01) and those for the Western diet and fast foods pattern were positively associated with the screen time (P-value for trend < 0.01). Adolescents in the top tertile of the scores for the Korean healthy dietary pattern had a multivariable-adjusted OR [95% CI] of 0.44 (0.25-0.75) for excessive screen time compared with those in the lowest tertile. On the basis of these findings, adolescents who have excessive screen time may need to be encouraged to consume a more healthy diet.

  • Children's drawings are widely used in the diagnosis of children's psychology as a means of expressing inner feelings. This paper proposes a children's drawings-based object detection algorithm applicable to children's psychology analysis. First, the sketch area from the picture was extracted and the data labeling process was also performed. Then, we trained and evaluated a Faster R-CNN based object detection model using the labeled datasets. Based on the detection results, information about the drawing's area, position, or color histogram is calculated to analyze primitive information about the drawings quickly and easily. The results of this paper show that Artificial Intelligence-based object detection algorithms were helpful in terms of psychological analysis using children's drawings.

  • Purpose: The purpose of this study was to develop a wisdom scale among Korean elderly with high validity and reliability. Method: The process of the development of this scale follows: A conceptual framework was identified based on literature a review of the elderly and discussion with experts in physiology and sociology. Total 128 items were developed. Through reliability testing, factor analysis, 60 preliminary items, and 4-points scale were selected. By a means of the internal consistency for 60 items, 33 items were deleted. Finally, 27 items were remained. To verity 27 items, factor analysis, reliability testing, and correlation were done. Data were collected from 480 elderly subjects in Daegu, Kyungpook Province, and Busan, Kyungnam Province from August, 2008 to February, 2009. Results: From the results of the factor analysis for 27 items, 3 factors were extracted. These factors were labeled as 'empathic emotion', 'self-reflection', and 'bitter experience of life'. Cronbach's Alpha for the 27 items was .921 and correlation coefficient of ego-integrity was .69. Conclusion: An exploratory study of the variables related to wisdom among the elderly is needed for criterion validity of this scale. A study on wisdom for different age groups is needed for re-verification.
