The purpose of this study is to provide for the basic data useful to the knitwear size standards for the effective production. For this purpose, knit promotions that product knitwear for 20 age $\sim$ 30 middle age women were sampled to survey their condition of the size designation and basic product size of knitwear, and their directors were surveyed through direct interviews. Data is processed by a computer(SPSS) and analyzed by using frequency, percentage, mean and mode. The results of this study are as follows. 1. Size designation and bodysize of knitwear are not standardized. 2. Knit promotions that don't mark bodysize on the size designation label are not a few. 3. Cardigan's sizes except for a few part are equal to round/pola T-shirt's sizes or are large more than those.

Defect size distribution is a probability density function for the defects that occur on wafers or glasses during semiconductor/LCD fabrication. It is one of the most important information to estimate manufacturing yield using well-known statistical estimation methods. The defects are detected by automatic optical inspection (AOI) facilities. However, the data that is provided from AOI is not accurate due to resolution of AOI and its defect detection mechanism. It causes distortion of defect size distribution and results in wrong estimation of the manufacturing yield. In this paper, I suggest a size conversion method and a maximum likelihood estimator to overcome the vague defect size information of AOI. The methods are verified by the Monte Carlo simulation that is constructed as similar as real situation.

This study investigates the effect of group size on group performance, here the quality of group decision, Four effects are proposed and tested in a field experimental setting : (1) the relationship between the group size and the distribution of individual's problem-solving ability ; (2) the change of the group decision quality as group size increases ; (3) the relationship between the group decision quality and the quality of the best/worst member as group size increases ; (4) the relationship between the group decision quality and the average quality of individuals in the group as group size increases. Data showed that contrary to the exiting results, group decision quality was not improved with the group size. Rather, it showed a little tendency that group decision quality was worsened with the group size. Data also showed that consensus-oriented group decision making process produced the compromised output. Thus, group decision quality was not better than the average group members'. The opinion of the best member was not accepted. The implications of the findings are discussed for the development of a Korean GSS.

The purpose of this study was to provide basic information requisite in the new sizing system for gloves. KS glove standards' size dimensions, size designation and labeling systems were analyzed. Also, KS glove standards' control sizes were compared to the anthropometric data of 824 Korean adults taken in the previous study. As well, the ISO hand size system was also compared to the anthropometric data of the previous study according to frequency tables of hand length and hand circumference. The size dimensions showed differences among KS standards and there was no size designation and labeling systems existed in KS standards. Among KS glove size systems, protective rubber gloves for radioactive contamination and surgical rubber gloves' size which followed ISO system were accurately indicate the hand size of the person a glove is intended to fit. ISO glove sizing system comprised the control dimensions of hand length and hand circumference. The coverage of ISO size A was 84.8% which was highest among ISO size A. B, C. And in hand circumference 178, 191, 203, 216mm showed the frequencies above 3% and in hand length 167, 175. 183, 191, 199mm showed the frequencies above 3%.

Over the last few decades, corporate frauds have highlighted the significance of corporate governance in deriving firm performance. By using different sample data, extensive research has examined how corporate governance structure influences firm's profitability, but limited research was undertaken on the banking sector of Pakistan. This research adds to the literature by testing how board structure derives bank's performance by using sample data of 19 banks for the period from 2010 to 2017. In addition, the study analyzes the controlling part of size on the link between board governance and bank performance. Findings reveal that banks having small board size, fewer non-executive directors and minimum activity level perform better. Analysis related to bank size illustrates that board size has value in increasing benefits in large size banks in contrast to small size one, while higher participation by board members enhances performance of small size banks more. The correlation results and findings showed that there existed no multicollinearity issue between independent variables. Board size showed positive correlation with the market variable, while board activity tended to correlated negatively with the market performance. Inverse correlation between board size and independent directors indicated that Pakistani banks with greater board size had fewer independent directors.

본 논문에서는 이전 연구에서 능동형 RFID 시스템의 태그 수집 성능 향상을 위해 제안된 인식 슬롯 스캔 기반 태그 수집 알고리즘의 단점을 개선하는 수정된 태그 수집 알고리즘을 제안한다. 기 제안된 인식 슬롯 스캔 기반 태그 수집 알고리즘은 태그 수집 과정에서 모든 태그들로부터 정해진 크기의 데이터를 수집하는 상황에 최적화 되어 있기 때문에 태그들이 다양한 크기의 데이터를 가지는 환경에 적용할 경우 제대로 된 성능 향상을 가져오지 못한다. 본 논문에서 새롭게 제안하는 개선된 태그 수집 알고리즘은 먼저 인식 슬롯 스캔 단계에서 각 태그로부터 자신이 가진 데이터를 전송하는데 필요한 슬롯 크기 정보를 획득하고 이를 활용하여 태그 수집 단계를 수행함으로써, 기 제안된 알고리즘의 문제점을 해결하고 모든 환경에서 능동형 RFID 태그 수집의 성능을 효율적으로 향상시키도록 설계되었다. 성능 평가를 위해 수행한 시뮬레이션 결과는 제안하는 개선된 태그 수집 알고리즘이 태그들이 동일한 데이터 크기를 가지는 환경에서는 기 제안된 알고리즘과 거의 동일한 성능을 보이고, 태그들이 다양한 데이터 크기를 가지는 환경에서는 기 제안된 알고리즘과 달리 ISO/IEC 18000-7 표준의 태그 수집 성능을 크게 향상시킴을 보여주었다.

We take genomic sequences of high-dimensional low sample size (HDLSS) without ordering of response categories into account. When constructing an appropriate test statistics in this model, the classical multivariate analysis of variance (MANOVA) approach might not be useful owing to very large number of parameters and very small sample size. For these reasons, we present a pseudo marginal model based upon the Gini-Simpson index estimated via Bayesian approach. In view of small sample size, we consider the permutation distribution by every possible n! (equally likely) permutation of the joined sample observations across G groups of (sizes $n_1,{\ldots}n_G$). We simulate data and apply false discovery rate (FDR) and positive false discovery rate (pFDR) with associated proposed test statistics to the data. And we also analyze real SARS data and compute FDR and pFDR. FDR and pFDR procedure along with the associated test statistics for each gene control the FDR and pFDR respectively at any level ${\alpha}$ for the set of p-values by using the exact conditional permutation theory.
