본 연구에서는 여가활동에 주기적으로 참여하는 베이비붐세대를 대상으로 여가열정과 자아실현 및 심리적행복감 간의 관계를 살펴보고 이를 바탕으로 베이비붐세대들의 여가스포츠 참여를 위한 기초자료를 제공하는데 그 목적으로 진행되었다. 본 연구는 서울 및 경기 지역에서 여가활동에 참여하고 있는 1995년~1963년 사이에 출생한 베이비붐세대를 연구대상으로 비확률 표본추출법(non-probability sampling) 중 편의표본추출법(convenient sampling method)을 이용하여 설문지를 작성하도록 하였다. 총 310명의 자료처리분석으로 연구의 목적을 달성하고자 SPSS 20.0 프로그램을 통해 빈도분석, 확인적 요인분석, 신뢰도분석, 상관관계분석, 구조방정식 모형분석을 실시하였다. 본 연구결과는 다음과 같다. 첫째, 여가열정은 자아실현에 영향을 미치는 것으로 나타났다. 둘째, 자아실현은 심리적행복감에 영향을 미치고 있다. 셋째, 여가열정은 심리적행복감에 영향을 미치는 것으로 나타났다. 따라서 베이비붐세대의 여가참여에 따른 여가열정과 자아실현, 심리적행복감의 관계에서 모든 경로가 통계적으로 유의한 영향을 미치는 것으로 나타났다. 또한 여가열정은 심리적행복감에 간접효과를 갖는 것으로 나타나 매개효과가 있는 것으로 나타났다.

A new configuration to realize the most general n-th order voltage transfer function is proposed. It employs only one operational transresistance amplifier (OTRA) as the active element. In the synthesis of the transfer function, the RC:-RC decomposition technique is used. To the best of author's knowledge, this is the first topology to be used in the realization of n-th order transfer function employing single OTRA.

In this note the geometric realization of a finite group of homotopy classes of self homotopy equivalences by a finite group of diffeomorphisms is investigated. In order for this to be accomplished an algebraic condition, which guarantees a certain group extension exists, must be satisfied. It is shown for a geometrically interesting class of aspherical manifolds, called injective Seifert fiber spaces over a locally symmetric space, that this necessary algebraic condition is also sufficient for geometric realization.

This paper proposes a new approach of balanced model reduction using matrix pencil. The algorithm presented in this paper is to convert full-rank high-order system into rank-deficient system using perturbation made by matrix pencil method. Then the system can be truncated to a low-order system that we want via balanced realization. We discuss the comparison with other methods and the various observations by simulations.

This paper investigates the theoretical properties of a logic element called the multithreshold threshold element, which is a generalization of the single-threshold threshold element. The primary partition os a systematic method of obtaining the multi-threshold realization of a switching function by the index numbers. The concept of comparable vertices of the same index numbers introduced in this paper is very promising for testing the multi-threshold partition by the initial condition to be defined by the minterms of the same index numbers.

Several model order reduction methods for large RLC circuits have been developed in the last few years. Krylop subspace based methods are extremely effective for generating the low order models of large system but there is no optimal theory for the resulting models. Alternatively, methods based truncated balanced realization have an optimality property but are too computationally expensive to use on complicated problems such as large RLC circuits. In this paper, we present a method for improving time domain response of reduced order RLC circuits. The method used here is based on combing Krylop subspace based method and truncated balanced realization method plus residualization. The metho...

In this paper, we report on a set of new algorithms to realize a nonlinear compressed-domain video/audio editor that overcomes various realization problems. For efficiency, the underlying algorithm, which uses a central data structure in the form of doubled linked lists, performs soft edits of cut and paste (which, in turn, involves soft implementations of frame type conversion) and addresses problems relating to video/audio synchronization and random access, and decoder buffer control.

Hardware realization of a digital 2-D homomorphic filter for real time contrast enhancement of video signal is presented. In homomorphic filter, logarithmic and exponential conversion used the memory lookup table method and because the hardware is implemented by multiplierless TTL devices, it can be designed to specific IC. The contrast gain can be controlled externally and the transfer function of homomorphic filter can be easily varied by the change of lookup table memory data.

This paper studies the realization of irreducible unitary representations of $GL_2(R)$ and $GL_2(C)$ by Bargmann's classification[1]. Since the representations of general matrix groups can be obtained by the extensions of characters of a special linear group, we shall follow to a large extent the pattern of the results in [5], [6], and [8]. This article is divided into two sections. In the first section we describe the realization of principal series and discrete series and complementary series of $GL_2(R)$. The last section is devoted to the derivation of principal series and complementary series of $GL_2(C).

In this paper, we evaluated the technological forecasting based on questionnaires of experts working in internet-banking industry. We prepared questionnaires on the 13 items. We examined specialties of respondents, relative importance of research contents, expected time of realization, likelihood of conviction on the expected time of realization, and their opinions on the levels of domestic's research and development comparing with advanced standards on each item. And we made various analysis based on data collected from Delphi method.
