Bayesian inference for a record value statistics(RVS) model of nonhomogeneous Poisson process is considered. We seal with Bayesian inference for double exponential, Gamma, Rayleigh, Gumble RVS models using Gibbs sampling and Metropolis algorithm and also explore Bayesian computation and model selection.

이 연구는 현재 우리나라 정부기관에서 시행되고 있는 단위과제 기반 기록물 평가의 문제점을 조사 분석하고 개선방안을 제시하기 위한 것이다. 이를 위해 중앙행정기관의 기록관리전문가 6명을 대상으로 집단 면담 및 개별 면담을 실시하고, 해당 기관 홈페이지에 고시된 기록관리기준표 조사를 병행함으로써 단위과제 기반의 평가방식이 기록의 보존기간 책정에 어떻게 적용되고 어떤 문제가 있으며, 문제 유형별 원인은 무엇인지를 분석하였다. 또한 문제 유형별 개선방안과 함께 단위과제 기반 평가의 제약을 극복하기 위한 새로운 다중 평가모형을 제안하였다.

문화재는 문화적 가치가 있다고 인정되는 선조의 문화 활동의 소산으로 역사상 또는 예술상 가치가 큰 것을 말한다. 이러한 민족의 자산인 문화재는 일단 훼손되면 다시 돌이킬 수 없는 것이기 때문에 그 보존과 전승은 매우 중요하다고 하겠다. 특히 무형문화재는 '일정한 형태가 없는 문화재'이기 때문에 그 특성에 맞는 적절한 보존과 활용이 이루어져야 한다. 이를 위해 본 연구에서는 16개 시 도지정무형문화재 기록화 현황을 살펴보고 바람직한 보존과 전승을 위한 효율적인 기록화 방안을 제시하였다.

Let { $X_{n}$ , n $\geq$ 1} be a sequence of independent and identically distributed random variables with a common continuous distribution function F(x) and probability density function f(x). Let $Y_{n}$ = max{ $X_1$, $X_2$, …, $X_{n}$ } for n $\geq$ 1. We say $X_{j}$ is an upper record value of { $X_{n}$ , n$\geq$1} if $Y_{j}$ > $Y_{j-1}$, j > 1. The indices at which the upper record values occur are given by the record times {u(n)}, n$\geq$1, where u(n) = min{j｜j>u(n-1), $X_{j}$ > $X_{u}$ (n-1), n$\geq$2} and u(1) = 1. We call the random variable X $\in$ Beta (1, c) if the corresponding probability cumulative function F(x) of x is of the form F(x) = 1-(1-x)$^{c}$ , c>0, 0$\leq$x$\leq$1. In this paper, we will give a characterization of the beta distribution of the first kind by considering conditional expectations of record values.s.

In this paper we establish some recurrence relations satisfied by quotient moments of upper record values from the exponential distribution. Let $\{X_n,\;n{\geq}1\}$ be a sequence of independent and identically distributed random variables with a common continuous distribution function F(x) and probability density function(pdf) f(x). Let $Y_n=max\{X_1,\;X_2,\;{\cdots},\;X_n\}$ for $n{\geq}1$. We say $X_j$ is an upper record value of $\{X_n,\;n{\geq}1\}$, if $Y_j>Y_{j-1}$, j > 1. The indices at which the upper record values occur are given by the record times {u(n)}, $n{\geq}1$, where u(n)=min\{j{\mid}j>u(n-1),\;X_j>X_{u(n-1)},\;n{\geq}2\} and u(1) = 1. Suppose $X{\in}Exp(1)$. Then $\Large{E\;\left.{\frac{X^r_{u(m)}}{X^{s+1}_{u(n)}}}\right)=\frac{1}{s}E\;\left.{\frac{X^r_{u(m)}}{X^s_{u(n-1)}}}\right)-\frac{1}{s}E\;\left.{\frac{X^r_{u(m)}}{X^s_{u(n)}}}\right)}$ and $\Large{E\;\left.{\frac{X^{r+1}_{u(m)}}{X^s_{u(n)}}}\right)=\frac{1}{(r+2)}E\;\left.{\frac{X^{r+2}_{u(m)}}{X^s_{u(n-1)}}}\right)-\frac{1}{(r+2)}E\;\left.{\frac{X^{r+2}_{u(m-1)}}{X^s_{u(n-1)}}}\right)}$.

This paper presents characterizations on the independence of the exponential and Pareto distributions by record values. Let ${X_{n},\;n {\ge1}$ be a sequence of independent and identically distributed(i.i.d) random variables with a continuous cumulative distribution function(cdf) F(x) and probability density function(pdf) f(x). $Let{\;}Y_{n} = max{X_1, X_2, \ldots, X_n}$ for n \ge 1. We say $X_{j}$ is an upper record value of ${X_{n},{\;}n\ge 1}, if Y_{j} > Y_{j-1}, j > 1$. The indices at which the upper record values occur are given by the record times {u(n)}, n \ge 1, where u(n) = $min{j|j > u(n-1), X_{j} > X_{u(n-1)}, n \ge 2}$ and u(l) = 1. Then F(x) = $1 - e^{-\frac{x}{a}}$, x > 0, ${\sigma} > 0$ if and only if $\frac {X_u(_n)}{X_u(_{n+1})} and X_u(_{n+1}), n \ge 1$, are independent. Also F(x) = $1 - x^{-\theta}, x > 1, {\theta} > 0$ if and only if $\frac {X_u(_{n+1})}{X_u(_n)}{\;}and{\;} X_{u(n)},{\;} n {\ge} 1$, are independent.

Primary function of health record is that as tool of communication between the health processionals with the mutual goal, the promotion of health care standard. Studies have been carried out world over oil tile subject, among those, Weed's Problem-Oriented Health Record is considered a paramount achievement. This study was designed to assess tile possibility of implementing tile problem-oriented health record system through ail experiment in order to provide data for nurse administrators infiltrating reformation of recording system and format. Record of 29 patients admitted at Korea University Hospital, Seoul, from March through June, 1976 for 4 to 14 days were sampled. Nursing notes were recorded by research assistants; senior nursing student trailed extensively by the researcher oil Problem-Oriented Records, oil Problem Oriented Nursing Record format (experimental group) and analysis were carried out comparative, with that of traditional nursing records noted by other nursing personnel (control group) on the same patient. Attitude towards Problem Oriented Nursing Record system and format were attained through questionaries responded by the 51 research assistants. Results are as fellows: Comparative analysis revealed that: 1. Assessment of patients' health problems recorded significantly more in traditional records. 2. Focus of health Problem differed; traditional records slowed significantly higher frequency in medical and procedure as focus while problem oriented records on nursing focus problems. 3. Problem- Oriented records were better organized, Mean value scores of attitude towards Problem- Oriented Records revealed that: Positive value scores on all 4 categories: 1) Assessment of nursing needs, 2) Nursing care planning 3) Patient progress assessment and 4) Tool of teaching and learning revealed that the Problem-Oriented Nursing Record is positively accepted by tile respondents. Recommendation Further experiments on implementation of Problem- Oriented Health Record are recommended: experiment involving all health professionals, in larger scope and longitudinal.

Generalized Pareto distributions play an important role in re-liability, extreme value theory, and other branches of applied probability and statistics. This family of distribution includes exponential distribution, Pareto distribution, and Power distribution. In this paper we establish some recurrences relations satisfied by the quotient moments of the upper record values from the generalized Pareto distribution. Further a char-acterization of this distribution based on recurrence relations of quotient moments of record values is presented.
