Axiomatic Design is the one of many useful methods for making a good design. In this method, the independency of Functional Requirements (FRs) is an important property to determine whether the design is good or not. Until now so many designers have decided the independency between FRs by their own decisions. The way depending on inspiration is simple and fast, but it can not be considered as a precise conclusion. Also there are not exact rule that evaluate the quantitative independence between FRs. This paper will show the way to evaluate the quantitative independence of FRs from the comparison between FRs of lower levels, and develop more efficient and objective tool in Axiomatic Design.

This study examined mothers' ratings of everyday rules for their young children. Participants were 294 mothers of 2- to 5-year-old children attending kindergartens and nursery schools in Korea. Data were collected by questionnaire and were analyzed by $x^2$. Results indicated that the majority of mothers' rules for their children pertained to safety, interpersonal issues, and as children got older, social conventions. Mothers endorsed prudential justifications for safety and self-care, moral justifications for interpersonal rules, practical and moral justifications for safeguarding property, and conventional justifications for obedience/order and food/mealtime routines. Analyses of mothers' judgments of rule independence indicated that rules on interpersonal and safety issues were to be kept without exception.

This thesis is a study on the properties of new religious ritual dress in Korea to help understand new religions more completely. A new religion means 'Newly born religions'and it is an opposite conception of the existing religion. The new religions in Korea have been established, changed and become extinct beginning with 'Dong-Hak'movement by Choi Jea Woo in 1860. Sometimes they've caused social problems with their number increasing after the rapid industrialization in 1970's. There are about 350 new religions and 2,000,000 christians in Korea now. Some of theme are pseudo religions wearing the mask of religion and also there are great new religions that will contribute to our spiritual history. The latter shows the thoughtful properties of the union of religion, postnatal creation, nation's independence, and human's centralization. There are properties of pluralism, nation's independence, symbolism, and thoughts in a new religious ritul dress.

The sampling plan CSP-1 for continuous production was first proposed by Dodge in 1943. Continuous production refers to products which are flowing past the inspection station such as products moving on a conveyor belt. One important measure of the effectiveness of a CSP is the average outgoing quality(AOQ). A concept for a short run of production length time, denoted by AOQ(t), is provided. The assumption of a s-independence in CSP-1 is unrealistic. It is possible to relax the assumption of a s-independence. The need for Markov model in a continuous production process can be discussed in this paper. The Markov and renewal theory are used to describe the property of AOQ in CSP-1.

In this paper, our central focus is upon gamma and beta q-distributions from a probabilistic viewpoint. The gamma and the beta q-distributions are characterized by investing the nature of the joint q-probability density function through the q-independence property and the q-Laplace transform.

In this paper a new type of filter, called the $H_2/H_{\infty}$ FIR filter, is proposed for discrete-time state space signal models. The proposed filter requires linearity, unbiased property, FIR structure, and independence of the initial state information in addition to the performance criteria in both $H_2$ and $H_{infty}$ sense. It is shown that $H_2,\;H_{\infty}$, and $H_2/H_{\infty}$ FIR filter design problems can be converted into convex programming problems via linear matrix inequalities (LMIs) with a linear equality constraint. Simulation studies illustrate that the proposed FIR filter is more robust against temporary uncertainties and has faster convergence than the conventional IIR filters.

결측치가 존재하는 비 단조형 데이터에 대한 패턴 분석과 비 내포형 종속 회귀 모형 분석에 격자 조건부 독립 모델이 최근 도입되고 있다. 이러한 접근 방법은 데이터 패턴 분석에 성공적으로 적용되고 있지만 격자 조건부 독립 모델을 찾는 계산적 부담이 따른다. 본 논문에서는 이러한 단점을 극복하기 위하여 에센셜 그래프를 바탕으로 격자 조건부 독립 모델(LCIM)을 찾는 새로운 방법을 제안한다. 또한, LCIM 클래스가 특정한 비 순환 방향 그래프 모델과 마르코프 동등한 모든 추이적 비 순환 방향 그래프의 모델 클래스와 일치함을 밝혔다.

본 연구는 경기도를 주요 분석대상으로 하여 공유재산 보유현황, 관리체제와 운영성과, 운영의 한계점 등을 분석하였다. 또한 경기도와 서울특별시, 인천광역시 등의 타 광역단체들의 공유재산 관리체제를 비교·분석하여 시사점을 얻고자 하였다. 동시에 경기도 전체 공유재산 실무담당자를 대상으로 공유재산 운영과 관련된 설문조사를 실시하였다. 분석결과, 경기도는 재정자립도가 완전하지 않기 때문에 재원확충이 중요인데도 불구하고 공유재산의 세외수입 실적이 보유규모에 비해 미미한 수준이다. 그 원인으로는 무엇보다도 공유재산 관리전담부서가 별도로 신설되어 있지 않고 기존의 업무를 담당하는 주무부서도 행정력이 부족하다는 점이 주요 원인이라 판단된다. 따라서 본 연구에서는 공유재산의 운영 성과와 기타 재산 가치를 증대시키기 위해서는 공유재산 전담부서를 신설할 것을 제안하고자 한다. 설문조사에서도 공유재산 운영 성과를 개선시키려면 현재의 관리체제를 개편해야 하며 그 개편방향은 전담부서의 신설이어야 한다는 인식이 형성되어 있음을 확인할 수 있었다.

Let {$X_i$, $1{\leq}i{\leq}n$} be a sequence of i.i.d. sequence of positive random variables with common absolutely continuous cumulative distribution function F(x) and probability density function f(x) and $E(X^2)$ < ${\infty}$. The random variables X + Y and $\frac{(X-Y)^2}{(X+Y)^2}$ are independent if and only if X and Y have gamma distributions. In addition, the random variables $S_n$ and $\frac{\sum_{i=1}^{m}(X_i)^2}{(S_n)^2}$ with $S_n=\sum_{i=1}^{n}X_i$ are independent for $1{\leq}m$ < n if and only if $X_i$ has gamma distribution for $i=1,{\cdots},n$.

In this paper, finite impulse response (FIR) smoothers are proposed for discrete-time systems. The proposed FIR smoother is designed under the constraints of linearity, unbiasedness, FIR structure, and independence of the initial state information. It is also obtained by directly minimizing the performance criterion with unbiased constraints. The approach to the MVF smoother proposed in this paper is logical and systematic, while existing results have heuristic assumption, such as infinite covariance of the initial state. Additionally, the proposed MVF smoother is based on the general system model that may have the singular system matrix and has both system and measurement noises. Thorough simulation studies, it is shown that the proposed MVF smoother is more robust against modeling uncertainties numerical errors than fixed-lag Kalman smoother which is infinite impulse response (IIR) type estimator.
