Statistical analyses used in clinical articles published on the Journal of Korean Neurosurgical Society were identified and appropriateness of statistical aspects in reporting results was assessed. Forty seven clinical articles were selected in this study, which were published from February, 2005 to February, 2006 on the journal. The frequency of statistical analysis was as follows : descriptive statistics only 24 [51.1%]. one type of statistical method 10 [21.3%], two or more methods 13 [27.6%]. An assessment of statistical aspects was performed in 24 clinical articles reporting inferential statistics. Ten articles [41.7%] did not adequately describe or reference all statistical methods used. There were six articles [25.0%] not reporting the confidence level used as the critical criteria of the statistical significance. In thirteen articles [54.2%] it seems more appropriate to implement multivariate analyses in addition to univariate analyses. We recommend that the journal readers should concentrate on improving their knowledge of basic statistics and statistical review for manuscripts submitted should be sought from professionals in the fields of biostatistics and epidemiology.

Dok island comprises Pliocene volcanic products such as a series of volcanoclastic rocks and lavas ranging in composition from alkali basalts, and trachyandesites to trachytes. Compositional variation of the basaltic rocks can be attributed to fractional crystallization of olivine, clinopyroxene, plagioclase, and magnetite. Chemical variations among the trachyandesites are caused by fractionation of clinopyroxene, plagioclase, and magnetite with minor amphibole, while trachytes are controlled mainly by feldspar fractionation. Incompatible element abundance ratios and chondrite normalized LREE/HREE ratios (e.g., (La/Yb)c: 24.8 to 32.8 for basalts, 15.6 to 31.2 for trachyandesites) suggest that the origins of the basalts and trachyandesites involve both different degrees of partial melting and subsequent fractional crystallization processes. Trace element ratios of the basalts from Dok island are characterized by high Ba/Nb, La/Nb, Ba/Th and Th/U and isotopic ratios (Tasumoto and Nakamura, 1991) that are similar to the EM 1 type of oceanic island basalts such as Gough and Tristan da Cunha basalts.

The constructions of LLS System is proceeded in cooperation with Korean Meteorological Administration & Korea Electrotechnology Research Institute in Korea. The system is composed of 1 position Analyzer & 10 Direction Finders, and can covers the full area of Korea. We show the configuration of this network and display of data. Finally, we refer to the future research in related with this system in Korea.

A preliminary survey of Sarcocystis species in the slaughtered cattle in Seoul was undertaken during October through December 1987, using digestion diagnostic technique for the heart muscle specimens digested in 0.5% trypsin solution. Results indicated that 41.5% of 159 bovine hearts were infected with Sarcocystis proliferative forms. High frequencies in the exotic dairy cattle(42.2%) and the Korean native cattle(41.7%) were noticed in comparison with low frequency in the cross breed(25.0%). No differences were indicated between the sexes of the host animals, although an age difference was noticed as 48.9% in cattle older than four years in comparison with 39.0% and 37.1% in younger than two years and in two to four years, respectively.

본 논문에서는 블록 이산 코사인 변환 (block discrete cosine transformation, BDCT) 부호화 영상에서 발생하는 구획화 결함 (blocking artifact)과 링잉 결함 (ringing artifact)을 제거하기 위하여 양방향 필터 (bilateral filter)를 이용한 새로운 후처리 방법을 제안하였다. 양방향 필터에서 파라미터 선택은 필터링 결과에 큰 영향을 주는 중요한 문제로 본 논문에서는 양방향 필터의 파라미터를 효과적으로 선택하는 방법을 제시하였다. 실험 결과는 제안된 방법이 부호화 결함을 효과적으로 개선함을 PSNR, MSDS, SSIM의 수치로 보였다.

The aim of this study is to classify the life styles of urban housewives, to see their correlation with demographic and socioeconomic variables, and finally to provide some useful for their ideal home management. This study has been based on a questionnaire on the demographic characteristics of housewives, and their life styles. The selected samples were 650 and 514 of them were analyzed. The data wee analyzed by factor analysis, cluster analysis, ANOVA, Duncan test and X2-test. As a result of factor and cluster analyses of 64 items th life styles of urban housewives were classified into 5 types; 'conservative stagnant type', 'sound and thrifty type', 'passive stagnant type', realistic and stable type', modern and evolutional type', The life styles of the respondents showed significant differences by the variables of age , family life cycles, the number of family members, the number of children, family type, education, occupation, income, the type of housing, and religion.

In this paper I argue that the subject in a Korean kes-cleft construction denotes the discourse referent that stands for the entity that satisfies the description of the cleft clause. This denotation thereby can be understood as a meta-linguistic referent which refers to the linguistic expression for a presupposed entity. In support of this claim, it is shown an anaphoric expression kekes also can be analyzed as a meta-linguistic referent. This analysis can explain why the subject and the predicate of a kes-cleft in Korean allow animacy crash.

This paper categorizes currently available theories of focus into two major types a 'discourse structure approach'(DSA) and a 'sentence structure approach'(SSA) The former DSA is intended to refer to a type of approach that analyzes focus only in terms of the discourse structure in which a focused sentence occurs. The alternative semantics approach which is the most widely available theory of focus belongs to this The latter SSA is meant to refer to a type of theory that analyzes focus in terms of sentence-internal structure, This study supports the SSA be revealing some empirical problems of the DSA that arise is analyzing two different kinds of focus, the A-accented focus and the B-accented focus (contrastive topic), and provides a brief sketch of a comprehensive analysis of focus and contrastive topic.
