This study aims to propose requirements for developing an integrated classification system for disaster and safety information by analyzing classifications currently used in disaster and safety-related organizations in Korea. To do that, this study first analyzed existing disaster category classifications. Then, it collected classifications currently used in disaster and safety-related organizations, and through interviews with practitioners, analyzed considerations to manage disaster and safety information comprehensively. The analysis shows that to develop a disaster category classification, consistency, exhaustivity, systemicity, and disasters frequently occurring in Korea should be considered. In addition, this study suggests a facet classification system for disaster and safety information given the intricacy of disaster and safety management and the occurrence of compound disasters.

Purpose: The classification of impacted maxillary third molars(IMTMs) facilitates interdisciplinary communication and helps estimate the degree of surgical difficulty. Thus, this study aimed to develop a 3-dimensional classification of the position and depth of impaction of IMTMs and to estimate their prevalence with respect to gender and age. Materials and Methods: This cross-sectional retrospective study analyzed images in sagittal and coronal cone-beam computed tomography (CBCT) sections of 300 maxillary third molars. The proposed classification was based on 3 criteria: buccolingual position (buccal, lingual, or central), mesial-distal position (mesioangular, vertical, or distoangular), and depth of impaction (low, medium, or high). CBCT images of IMTMs were classified, and the associations of the classifications with gender and age were examined using analysis of variance with the Scheffe post-hoc test. To determine the associations among the 3 classifications, the chi-square test was used (P<.05). Results: No significant association of the classifications with gender was observed. Age showed a significant relationship with depth of impaction (P=.0001) and mesial-distal position (P=.005). The most common positions were buccal(n=222), vertical(n=184), and low (n=124). Significant associations among the 3 tested classifications were observed. Conclusion: CBCT enabled the evaluation of IMTMs in a 3-dimensional format, and we developed a proposal for a new classification of the position and depth of impaction of IMTMs.

This study clarified the classifications of Vietnamese traditional patterns and analyzed the symbolic meanings that reflect the emotional and cultural background of the Vietnamese. The type and symbolism of Vietnamese traditional patterns were analyzed through research on the history of Vietnamese costumes, the history of Vietnamese arts, the history of Vietnamese traditional culture, and a Vietnamese museum survey. The results of this study were as follows: 1. Animal patterns are diverse and include dragons, unicorns, tortoises, phoenixes, cranes, lions, bats, tigers, and buffalo patterns. 2. Dragon patterns are the most utilized pattern for practical purposes. They are often used in royal costumes, Vietnamese traditional dresses, mandarin boots, bamboo fans, silk, satin, ceramics, and other detailed decorations. 3. The patterns symbolized fortune that meant good luck and longevity so people can live long and happy. Then the symbolic meanings of patterns were followed by prosperity, nobleness, apotropism, prolificacy, and wealth. 4. Since the most of animal patterns have symbolic meanings of fortune and longevity, animal patterns can be utilized as the source of traditional patterns of design inspiration for the development of Vietnamese modern patterns and the application on Vietnamese fashion products.

Principal component analysis (PCA) was used to improve image classification by the unsupervised classification techniques, the K-means. To do this, I selected a Landsat TM scene of Jeju Island, Korea and proposed two methods for PCA： unstandardized PCA (UPCA) and standardized PCA (SPCA). The estimated accuracy of the image classification of Jeju area was computed by error matrix. The error matrix was derived from three unsupervised classification methods. Error matrices indicated that classifications done on the first three principal components for UPCA and SPCA of the scene were more accurate than those done on the seven bands of TM data and that also the results of UPCA and SPCA were better than those of the raw Landsat TM data. The classification of TM data by the K-means algorithm was particularly poor at distinguishing different land covers on the island. From the classification results, we also found that the principal component based classifications had characteristics independent of the unsupervised techniques (numerical algorithms) while the TM data based classifications were very dependent upon the techniques. This means that PCA data has uniform characteristics for image classification that are less affected by choice of classification scheme. In the results, we also found that UPCA results are better than SPCA since UPCA has wider range of digital number of an image.

Morphological and molecular classifications were attempted in an effort to establish species-specific classifications of three species of the genus Pholis in Korea; these species were subjected to morphological and molecular methodologies using body measurements, RFLP, RAPD, and phylogenetic trees using the nucleotide sequences of mitochondrial 16S and 12S ribosomal DNAs, cytochrome c oxidase I, and cytochrome b. The data demonstrated that the three species of genus Pholis are distinct from each other, both morphologically and genetically.

Allergic diseases, including allergic rhinitis, asthma, and atopic dermatitis, are common heterogeneous diseases that encompass diverse phenotypes and different pathogeneses. Phenotype studies of allergic diseases can facilitate the identification of risk factors and their underlying pathophysiology, resulting in the application of more effective treatment, selection of better treatment responses, and prediction of prognosis for each phenotype. In the early phase of phenotype studies in allergic diseases, artificial classifications were usually performed based on clinical features, such as triggering factors or the presence of atopy, which can result in the biased classification of phenotypes and limit the characterization of heterogeneous allergic diseases. Subsequent phenotype studies have suggested more diverse phenotypes for each allergic disease using relatively unbiased statistical methods, such as cluster analysis or latent class analysis. The classifications of phenotypes in allergic diseases may overlap or be unstable over time due to their complex interactions with genetic and encountered environmental factors during the illness, which may affect the disease course and pathophysiology. In this review, diverse phenotype classifications of allergic diseases, including atopic dermatitis, asthma, and wheezing in children, allergic rhinitis, and atopy, are described. The review also discusses the applications of the results obtained from phenotype studies performed in other countries to Korean children. Consideration of changes in the characteristics of each phenotype over time in an individual's lifespan is needed in future studies.

The intention of this article is to check for the believers in Daesoonjinrihoe how to perceive the gods who they believe in. For that intention, I explained how the perception of gods in Daesoonjinrihoe is different from the perception of gods in other religions. To make a long story short, because of its polytheism the idea of god in Daesoonjinrihoe is different from monotheism such as Christianity, Islam. In addition, in spite of its polytheism it is different from other polytheism such as the religion in ancient India, especially rig-vedicreligion. In this article it is said that the believers in Daesoonjinrihoe have understood the distinction between Shin(神) and Shinmyung(神明). Nowadays Shin that has been used in Korea, China, Japan, is the word that was translated from English god. Therefore we need to reappraise the meaning of the word Shin. Anyway Shin that is being used in general means Shinmyung in Daesoonjinrihoe. Instead when they say the name of functional gods and the name to which the meaning of its origin affixed, the word Shin is used. Meanwhile, it has the advantage of classifying the ideas of god, but we can't explain all of them through the use of those classifications. I checked some classifications in this article and tried to apply the idea of gods in Daesoonjinrihoe. As a result, each classification has some critical points. There fore in this article I explained the distinguishing ideas of god in Daesoonjinrihoe from that in other religions, instead of the explaining fitted those classifications.

The objective of this study is to understand disordered parent-child relationships of Reactive Attachment Disorder(RAD) systematically through the mother’ internal working model of child. In this study, RAD mothers’internal representations of the child were compared with mothers’of control group and association between mothers’ representation classifications and children’ attachment classifications was examined. Also individual differences in mother-child interaction by mothers’representation classifications was observed. The subjects of this study were 40 2-5 year-old children and their mothers, 20 attachment disordered dyads and 20 normal dyads of control group. Mothers were interviewed using the Working Model of the Child(Zeanah, Benoit & Barton 1986) to classify internal representations of child. Children’ attachment patterns were assessed by the Strange Situation Procedure. For observation of motherchild interaction, Each dyad was seen in DPICS devised by Eyberg and Robinson(1983). The results of the study were as follows：1) Among RAD group, 55% of mothers were classified as disengaged and 45% classified as distorted, while all mothers of control group were classified as balanced. In rating scales, there were significant differences in all 3 representation classifications in Intensity of involvement and Coherence. In Intensity of involvement disengaged representations had the lowest score and distorted representations had the lowest score in Coherence. 2) Mothers’representation classifications were related to children’ attachment classifications. All mothers of control group whose children were classified as secure were classified as balanced. Among RAD’ mothers, by contrast, 82% of mothers classified as disengaged had children classified as anxious-avoidant, 56% of mothers classified as distorted had children classified as disorganized / disoriented and 33% of mothers classified as distorted had children classified as anxious-resistant. 3) There were individual differences in mother-child interactions by mothers’representation classifications. In the child-centered play, mothers classified as disengaged used discriptive statement, reflective statement and discriptive-reflective question less than balanced mothers. Mothers classified as distorted used direct command and indirect command more than balanced mothers. In the clean-up task, mothers classified as disengaged and distorted used direct command and indirect command more than balanced mothers. The results of this study suggest that parents’working model of the child is an important factor to understand parent-child attachment relationships and their interactions. The understanding of parents’ working model of the child is thought to enrich our understanding of disordered parent-child relationships and to provide useful informations for specific and successful treatments.

This paper describes the design of a high-performance unified SVM classifier circuit. The proposed circuit supports both linear and non-linear SVM classifications. In order to ensure efficient classification, a 48x96 or 64x64 sliding window with 20 window strides is used. We reduced the circuit size by sharing most of the resources required for both types of classification. We described the proposed unified SVM classifier circuit using the Verilog HDL and synthesized the gate-level circuit using 65nm standard cell library. The synthesized circuit consists of 661,261 gates, operates at the maximum operating frequency of 152 MHz and processes up to 33.8 640x480 image frames per second.
