We classified Abell clusters using the magnitude differences between two or three bright member galaxies and investigated how such classification was correlated with the properties of brightest cluster galaxies (BCGs). S-type BCGs being clearly brighter than the rest of the member galaxies were likely to be red, luminous, and evolved as early type galaxies. On the other hand, T-type BCGs being not dominant at all were less luminous than early type galaxies. A small fraction of BCGs was currently forming stars, and all of the star-forming BCGs were T-type BCGs. Active galactic nuclei were most frequent for S-type BCGs. Through these quantitative analyses of the BCG properties, we discussed the possible scenario of BCG formation and the differences between S-type and T-type of BCGs.

As we review the mechanism regarding digital font generation and birth of TrueType font, we realizes that the process is composed of sequential steps such as contour fonts from glyph table. This fact implies that we propose classification of TrueType font in terms of segment width and the number of occurrence from the glyph data.

Endobronchial tuberculosis is a serious disease which is frequently complicated with bronchial stenosis, and it may simulate a bronchial asthma or bronchogenic carcinoma. We have analyzed the clinical characteristics of endobronchial tuberculosis in 166 patients, and we introduce new classification of endobronchial tuberculosis. Endobronchial tuberculosis is classified into seven subtypes as stenotic type with fibrosis, stenotic type without fibrosis, actively caseating type, tumorous type, ulcerative type, granular type and nonspecific bronchitic type, according to the bronchoscopic findings. Actively caseaing type, stenotic type without fibrosis, nonspecific bronchitic type and stenotic type with fibrosis are predominant in the order of frequency, but ulcerative type and granular type are relatively rare. Stenotic type with or without fibrosis, actively caseating type and tumorous type of endobronchial tuberculosis are closely related to bronchial stenoses. We believe that our new classification of endobronchial tuberculosis, which is based on bronchoscopic features, is helpful to understand the pathogenesis of disease and to make a therapeutic plan for preventing or minimizing bronchial stenosis.

Remote sensing techniques using satellites or the scanning weather radars depend mostly on the presence of clouds or precipitation, and leave the extensive regions of clear air unobserved. But wind profilers provide the most direct measurements of mesoscale vertical air motion in the troposphere, even in the context of heavy precipitation. In this paper, the precipitation events during the Changma period was classified into 4 precipitation types - stratiform, mixed stratiform/ convective, deep convective, and shallow convective. The parameters for the classification of analysis are the vertical structure of reflectivity, Doppler velocity, and spectral width measured with the wind profiler at Haenam for a three-year period (2003-2005). In addition, the synoptic fields and total amount of precipitation were analyzed using the Global Final Analyses (FNL) data and the Global Precipitation Climatology Project (GPCP) data. During the Changma period, the results show that the stratiform type was dominant under the moist-neutral atmosphere in 2003, whereas the deep convective type was under the moist unstable condition in 2004. The stratiform type was no less popular than the deep convective type among four seasons because the moist neutral layer was formed by the convergence between the upper-level jet and the low-level jet, and by the moisture transport along the western rim of the North Pacific subtropical anticyclone.

사서교사가 독서교육을 성공적으로 수행하기 위해서는 독서에 관한 학생들의 특성을 파악하고 있어야 한다. 그러나 현재 학생들의 독서 관련 특성을 파악하기 위한 도구가 미흡한 실정이다. 이에 본 연구에서는 구조방정식 모형을 이용하여 독서 플로우 유형을 분류하고 독서 플로우 유형을 측정할 수 있는 검사도구를 제안하였다. 독서 플로우의 유형을 분류하기 위해서 4개의 연구모형(워너, 던과 던, MBTI, flow 구성모형)을 설정하고 각 모형을 AMOS 구조방정식 모형에 대입하여 적합성을 검증하였다. 그 결과 4개의 연구모형 중 flow 구성 모형이 가장 적합한 모형임을 확인하였다. flow 구성 모형을 바탕으로 독서 플로우 유형을 분류하고 독서 플로우 유형 검사를 위한 도구를 제안하였다. 제안한 독서 플로우 유형은 4 차원 16 가지의 세부 유형으로 구성되고 있고 검사도구는 4개 영역, 28개 문항으로 설정하였다. 본 연구에서 사용한 데이터는 본 연구자의 선행연구를 위해 수집한 1,836개의 데이터를 재사용하였다.

The purpose of this study was to provide basic information for obese boy's clothing construction that can reflect the characteristics of their bodies. The subjects for anthropometric measurements which were performed directly were obese boys of 9 to 11 year-old. To classify the somatotype and to analyze the characteristics of each somatotype 310 obese boys were examined. Data were analyzed by using multivariate method, By means of Ward the subjects were classified into 4 clusters according to the factor scores which were obtained from 6 factors providing the information of 54 items. 4 clusters were identified. 1) Type I was characterized by tall and obese type 2) Type II was characterized by short and small type 3) Type III was characterized by long and obese type of lower body. 4) Type IV was characterized by short and obese type.

This research examines classifying and characterizing breast form's classification on elderly women, 242 subjects from 55 to 75 years of age participated. 27 direct anthropometric measurement were applied to classify the breast typesl. We analyzed measurement data using factor analysis, cluster analysis, analysis of variance. The results of the study were as follows. 1) 55-64 aged group was taller and higher than 65-79 aged group. Typical breast form in 55-64 aged group was more obese than breast form in 65-79 aged group. 2) We extracted 5 factors(obesity of breast, height of breast, height of breast items, location & size of breast, width of upper chest & shouldet length, height of breast & lower length of nipples) from total items through factor analysis. 3) Through cluster analysis, we categorized 3 clusters. Namely, type 1; characterized the best slender type, type 2; characterized middle sized type, type 3: characterized obesity type. Type 2 is the typical type on elderly women.

The purpose of this study was to classify the somatotype of elderly women and to extract discriminant factors of the classification. The subjects were 218 elderly women aged 60-85 years old. Data were collected from 46 anthropometric and photographic measurements of each subject and analyzed by frequencies, crosstabs, analysis of variance and discriminant analysis. The somatotype was classified into 5 types according to the lateral view. The normal type was defined as the type which the plumb line passes through the cervicale and the lateral malleolus. The lean-back type positioned the plumb line more posteriorly than normal type. The swayback type positioned the plumb line at about the same line as the lean-back type, but curvature of lateral view was prominent. The lean-forward type I and II positioned the plumb line more anteriorly than normal, but the spinal curvature of the type II disappeared. As the result of discriminant analysis, significant discriminant factors of anthropometric measurement were cervicale height, anterior waist height, neck point to posterior waist length, anterior waist length. Photographic measurement were C valve, D value, ∠${\alpha}$ and ∠${\beta}$.

Observed spectra of supernovae allow the empirical classification of supernovae into two basic categories, Type I with little or no evidence of hydrogen, and Type II with obvious evidence for hydrogen. The broad class of Type I can be subdivided depending on whether helium or silicon and other intermediate mass elements is observed. Understanding the physical processes that underlie these classifications---the progenitor evolution. the explosion mechanism, and end products---requires calculation of radiative transfer and model spectra. While most Type II occur in evolved massive stars that undergo core collapse. some may span the dividing line between degenerate and non-degenerate carbon burning and involve both core collapse and thermonuclear explosion. Type Ia are still most plausibly explained as thermonuclear explosions in carbon/oxygen white dwarfs in binary systems. Type Ib reveal helium atmospheres and are probably the result of core collapse in the helium core of a massive star that has lost its hydrogen envelope to a binary companion or to a wind. Type Ic supernovae are probably related to Type Ib but have also lost their helium envelope to reveal a mantle rich in oxygen.
