This experiment was performed to compare the techniques of the metabolizable energy determination and to, examine the problems associated with metabolizable energy determination of poultry feedingstuffs. The feedingstuffs evaluated herein, were corn, sorghum, barley. fish meal and soybean meal The results obtained were as followings : 1. When comparing AME and AMEn values of five feedingstuffs(measured) by Total Collection ana Index Methods there was no significant difference (P＞.05) between two methods except fish meal. 2. The AME$_{F}$ values of feedingstuffs were not different (P＞.05) from AME values. which implied that bioassay of AME$_{F}$ be applicable to rapid measure AME value of feedingstuffs for poultry and the problems connecting to AME$_{F}$ determination were discussed. 3. The AME$_{FC}$ and TME values of corn, sorghum and barley were significantly higher (P＜.05) than AME and AME$_{F}$ values but those of fish meal and soybean meal were similar or lower than AME and AME$_{F}$ values. This fact was indicative that the techniques measuring AME$_{FC}$ and TME has some depressing factors when fish meal and soybean meal were determined. 4. Comparing of TME, AME$_{FC}$ and T-AME values tile TME values of corn sorghum and barley were significantly higher(P＜.05) than AME$_{FC}$ and T- AME values. But that of fish meal and soybean meal was much lower(P＜ .05)comparing with AME$_{FC}$ and T-AME values. According]y, it night be concluded that the relationship among the values of TME. AME$_{FC}$ and T-AME was shown great variation according to the feedingstuffs, especially in the protein diets.

A parametric empirical Bayes procedure is proposed and studied to compare treatments simultaneously with the best. Minimum Bayes risk lower bounds are derived for an additive loss function, and their relationship with Bayesian simultaneous confidence lower bounds is given. For the proposed empirical Bayes procedure, the nominal confidence level both in Bayesian sense and in frequentist's sense is shown to be controlled asymptotically. For practical implementation, a measure of significance similar to f-value is suggested with an illustrative example.

In this note we find the upper bound for ${\rho}(u^n,M)=\int_{0}^{T}\int_{0}^{{\mid}u(t){\mid}^n}p(s)dsdt$ and show that $F(y)=y^n$ is $m_{\phi}^M$-Bochner integrable on $C(\mathcal{O} _M)$ for $0{\leq}t{\leq}T$ when $\int_{\mathcal{O}_M}{\parallel}u_0{\parallel}_M^nd{\phi}(u_0)$ is finite.

본 논문에서는 이 문서 클러스터링 방법 중 계층적 방법인 Kmeans 클러스터링 알고리즘을 이용하여 문서를 클러스터링 하고자 한다. 기존의 Kmeans 클러스터링 알고리즘은 문서의 수가 많을 경우 하나의 클러스터링에 너무 많은 문서들이 할당되는 문제점이 있다. 이 치우침을 완화하고자 각 클러스터링에 할당된 문서 수에 따라서 문서에 가중치를 부여한 후 다시 클러스터링을 하는 방법을 제안하였다. 실험 결과는 정확률, 재현율을 결합한 조화 평균(F-measure)을 사용하여 평가하였으며 기존 알고리즘보다 9％이상의 성능 향상을 나타냈다.

This study was performed at Sa-Sang Industrial area in Pusan City. To measure the total suspended particulates(T.S.P) and $SO_3$ following places was selected industrial area, down town, residentail area. T.S.P was collected on glass filters by High-Volume Air Sampler, $SO_3$ was measured by PbO2 Candle method. The collected T.S.P was analyzed for various anlon(for example, $NO_3$, $SO_4$, $PO_4$, F, Cl) by ion Chromatography, and Pb by Inductively Coupled Plasma.

본 논문은 인터넷의 대표적인 문제점중의 하나인 Adult Image 분류 연구에 대해 기술한다. 특히 우리는 이러한 Adult Image를 분류하기 위한 Data Set을 5가지 타입으로 구성한다. 이러한 각 Image에 대해 Color, Gradient, Edge Direction 특성의 Feature들을 추출하고 이를 Histogram으로 구성한다. 이렇게 구성된 Histogram을 Support Vector Machine에 적용하여 Adult Image를 분류한다. 그 결과, 우리는 8250개의 Test Set에 대하여 Recall(96.53%), Precision(97.33%), False Positive(2.96%), F-Measure(96.93%)의 성능 결과를 보여준다.

A sequence {$X_n,\;n{\geq}1$} of independent and identically distributed random variables with absolutely continuous (with respect to Lebesque measure) cumulative distribution function F(x) is considered. We obtain two characterizations of a family of continuous probability distribution by independence property of record values.

In this note, we discuss measure theoretic characterizations for weighted composition operators in some operator classes on $L^2(\cal{F})$ such as, p-quasihyponormal, p-paranormal, p-hyponormal and weakly hyponormal. Some examples are then presented to illustrate that weighted composition operators lie between these classes.

In this paper we consider an age dependent branching process whose particles move according to a Markov process with continuous state space. The Markov process is assumed to the stationary with independent increments and positive recurrent. We find some sufficient conditions for he Markov motion process such that the empirical distribution of the positions converges to the limiting distribution of the motion process.

An extension of $H\"{o}lder's$ inequality whose discrete form is described as follows is given. Let $\nu$ be a positive measure on a space Y, $\nu(Y)\;\neq\;0$, and let $f_{j}$(j = 1,2,...,n) be positive ν-integrable functions on Y. If ${\alpha}_j$ > 0(j = 1,2,...,n) and ${\beta}_j$(j = 1,2,...,k < n) are related to be (equation omitted) then (equation omitted).
