Let B be the open unit ball in the complex space $\mathbb{C}^n$. A holomorphic function $f:B{\rightarrow}C$ which satisfies sup{(1- ${\parallel}\;{\nabla}_zf\;{\parallel}\;{\mid}z{\in}B$} < $+{\infty}$ is called Bloch type function. In this paper, we will find some integral representation of Bloch type functions.

Sufficient conditions are given under which a generalized class of kernel-type estimators allows asymptotic approximation on the modulus of continuity. This generalized class includes sample distribution function, kernel-type estimator of density function, and an estimator that may apply to the censored case. In addition, an application is given to asymptotic normality of recursive density estimators of density function at an unknown point.

분석심리학에서 심리학적 유형론은 의식의 자아의 기능과 태도를 구분하려는데 사용할 뿐만이 아니라 개성화과정을 위한 청사진으로서 활용될 수 있다. 우리는 개성화 과정을 추구하기 위하여 주기능과 이차기능, 삼차기능 그리고 열등기능 배열에 대한 인식과 그것을 의식화하기 위하여 발달시키는 과정이 매우 중요하다. 이 연구는 심리학적 유형의 기능의 발달과 배열에 대하여 상세하게 인식하는 데에 도움을 줄 수 있는 도구에 대한 것이다. 브리그스 마이어스 유형 검사와 그레이 휠라이트 융 유형검사는 양극성 가설을 배경으로 하여 강제적인 질문지 선택 문항의 방식으로 질문지가 구성되어 있다. 그러나 싱어 루미스 심리유형검사는 리커트 스케일을 사용한다. 싱어루미스 심리 유형검사는 주기능, 이차기능, 삼차기능 그리고 열등기능의 배열을 확연하게 보여줄 수 있다. 또한 이 검사는 개인의 심리학적 유형의 발달과 변화를 확인하기 위하여 일정 기간에 걸쳐서 반복 측정하여 비교하는 것이 용이하다. 이러한 측면에서 싱어 루미스 검사는 타 심리유형 검사에 비교하여 우월하다고 볼 수 있다. 본 연구자는 한국판 싱어 루미스 유형 검사 제작을 위한 예비 연구로서 한국판 싱어 루미스 검사의 신뢰도 연구를 하였다. 유형문항 간의 차이 검증과 신뢰도 계수 α를 분석하여 검사의 문항의 내적 일관성을 산출하였고, 각 유형에 따라서 문항 분석을 하고 그 결과에 의하여 수정이 필요한 문항들의 수정본을 제시하였다

The purpose of this study was to identify the types of social networks of urban housewives according to different network composition patterns and to analyze the structural and functional characteristics of identified types. The data used in this study were collected from 589 full-time housewives residing in Taejeon city. The major findings are as follows: 1) The social networks of housewives in urban nuclear families were classified into eight types: the kin network, the non-kin network, the kin-centered network, the friend-centered network, the neighbor-centered network, the associate-centered network, the parallel network, and the decentralized network. 2) The structual characteristics (size, density, homogeneity, duration, proximity, frequency, closeness, direction) varied according to the type. The kin network type and the non-kin network type showed extreme degrees in network characteristics. The parallel network type and the decentralized network type showed an average level of network characteristics. The kin-, friend-, neighbor-, and the associate-centered types showed network characteristics of an intermediate level between the single-category types and the decentralized type. 3) The average levels of function of social network types were different in only two(service support, interference) of the six function areas(emotional support, service support, material support, information support, social companionship support, interference). The average level of service support by the non-kin network type was higher than other types. The average level of interference by the kin-centered network type was higher than other types, and that of the neighbor-centered network type was lower than other types. On the other hand, the total amount of function performance of social network types was different in all function areas. The total amount of social support given by the decentralized network type was greater than the other types. The total amount of interference given by the non-kin network type was smaller than the other types.

In this article, we discuss classes of generalized functions for certain modified integral operator of Bessel-type involving Fox's H-function kernel. We employ a known differentiation formula of Fox's H-function to obtain the definition and properties of the distributional modified Bessel-type integral. Further, we derive a smoothness theorem for its kernel in a complete countably multi-normed space. On the other hand, using an appropriate class of convolution products, we derive axioms and establish spaces of modified Boehmians which are generalized distributions. On the defined spaces, we introduce addition, convolution, differentiation and scalar multiplication and further properties of the extended integral.

The main aim of this paper is to establish a new class of integrals involving the generalized Galu$Galu{\grave{e}}$-type Struve function with the different type of polynomials such as Jacobi, Legendre, and Hermite. Also, we derive the integral formula involving Legendre, Wright generalized Bessel and generalized Hypergeometric functions. The results obtained here are general in nature and can deduce many known and new integral formulas involving the various type of polynomials.

현재 우리나라의 설계속도는 도로의 기능, 지역특성, 지형에 의해 결정하도록 규정하고 있다. 그러나 도로의 기능을 구분하는 뚜렷한 기준이 없어 적정 설계속도 결정에 설계자의 주관이 개입될 여지가 많으며, 기능분류가 단순하여 설계에 반영되지 못하는 도로기능이 존재하고, 지역분류기준 또한 모호하여 주변지역의 토지이용 특성을 제대로 반영하지 못하였다. 한편 도로가 통과하는 지역의 지형적 특성을 충분히 고려치 않고 단순히 교통소통 만을 강조하여 지나치게 높은 설계속도로 설계하여 도로의 건설비가 증가하고 있다. 따라서 본 연구에서는 지방부 도로 기능분류 및 설계속도 결정에 계획교통량 규모를 반영토록 하여 설계자의 주관적 판단소지를 줄이고 경제적 효율성을 기하였으며, 도시부 기능을 세분화하여 기능분류의 단순함과 설계에 반영되지 못하는 도로의 기능이 존재하는 문제를 해결하였다. 또한 GIS의 지형고도 데이터를 이용하여 지형을 구분하는 구체적 기준을 제시하였다. 즉 기능, 지역, 지형요소를 보다 세분하여 고려하고, 보완기준으로 계획교통량을 추가한 새로운 기능분류와 설계속도 결정기준을 제시하였다.

Software reliability in the software development process is an important issue. Software process improvement helps in finishing with reliable software product. Infinite failure NHPP software reliability models presented in the literature exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, proposes the reliability model with log type mean value function (Musa-Okumoto and log power model), which made out efficiency application for software reliability. Algorithm to estimate the parameters used to maximum likelihood estimator and bisection method, model selection based on mean square error (MSE) and coefficient of determination($R^2$), for the sake of efficient model, was employed. Analysis of failure using real data set for the sake of proposing log type mean value function was employed. This analysis of failure data compared with log type mean value function. In order to insurance for the reliability of data, Laplace trend test was employed. In this study, the log type model is also efficient in terms of reliability because it (the coefficient of determination is 70% or more) in the field of the conventional model can be used as an alternative could be confirmed. From this paper, software developers have to consider the growth model by prior knowledge of the software to identify failure modes which can be able to help.

This paper introduces the method to develop two main types of the fuzzy OEE (Overall Equipment Effectiveness) models via triangular membership function for measuring uncertainty. The fuzzy OEE includes model type 1 and model type 2. The model type 1 is used when the theoretical machine speed only reflects the time loss whereas model type 2 is used when the actual machine speed reflects both time and speed loss. Model type 2 has shown to perform a lower availability rate and a higher performance rate compared to model type 1. In addition, the fuzzy UPH (Unit Per Hour) which is derived from using the fuzzy OEE is presented to satisfy demand uncertainty. The fuzzy UPH can easily measure the fuzzy tact time and cycle time by reciprocating itself. Finally, this study demonstrates the fuzzy OEE models using IVIFS (Interval-Valued Intuitionistic Fuzzy Set) based on the characterization via membership function, non-membership function and hesitant function. For the purpose of analyzing the fuzzy system OEE, the OEE for each machine of plant structure is considered triangular interval-valued intuitionistic fuzzy number. Regardless of plant structure, the validity degree of fuzzy membership function of system OEE decreases when the number of machine with worst value of the validity degree increases. Corresponding examples are presented in this paper for practitioner to understand the applicability and practicability of the proposed fuzzy OEE methods.
