Purpose: The purpose of this study was to draw practical implications applicable to the field by analyzing a double-mediator model of social participation and depression in relation to the utilization of Information Communication Technology (ICT) and cognitive function. Methods: The data from the Fifth Living Profiles of Older People Survey in Korea was used, and the sample included 3,925 people, 75 years of age or older. Descriptive statistics, correlation analysis, and the PROCESS macro test were used for verification of the double mediator model. Results: The results were as follows: First, ICT utilization was rated at an average of 1.4 out of 10, social participation at an average of 1.1 out of 7, depression at an average of 3.72 out of 15, and cognitive function at an average of 22.42 out of 30. Second, ICT utilization has a significant effect on cognitive function. Third, the mediating effects of social participation between ICT utilization and cognitive function were significant. Fourth, the mediating effects of depression between ICT utilization and cognitive function were not significant. Fifth, the serial double mediator effects leading to ICT utilization, social participation, depression, and cognitive function were significant. Conclusion: The study discussed the implications of maintaining and protecting cognitive function in the vulnerable elderly through the utilization of ICT.

본 연구는 영남지역 H사 전속보험설계사를 대상으로 MBTI 성격유형에 따른 직무만족의 차이와 직무만족이 고객지향성과 이직의도에 미치는 영향, 그리고 고객지향성과 이직의도에 미치는 직무만족의 영향이 MBTI 성격유형에 의해 조절되는지를 살펴보았다. 자료수집은 2014년 3월 20일부터 4월 20일까지 약 4주간에 걸쳐서 실시되었다. 총 120명의 영남지역 H보험설계사들을 대상으로 MBTI 테스트를 실시하였고, 본 논문의 가설관련 문항들이 포함된 120부의 설문지를 배포하여 일관성 및 성실성이 떨어진다고 판단되는 14부를 제외한 106부가 가설검증에 이용되었다. 연구결과는 다음과 같다. 첫째, MBTI 성격유형(심리적 기능과 태도지표)에 따른 직무만족은 유의한 차이가 없는 것으로 나타났다. 둘째, 직무만족은 고객지향성에 긍정적인 영향을 미치는 것으로 나타났으며, 이직 의도에는 부정적인 영향을 미치는 것으로 나타났다. 셋째, MBTI 성격유형의 조절효과 분석결과는 심리적 기능과 태도지표로 구분하여 정리할 수 있다. 먼저 심리적 기능의 조절효과는 직무만족과 고객지향성 간의 관계에서만 유의한 것으로 나타났고 직무만족과 이직의도 간의 관계에서는 유의하지 않은 것으로 나타났다. 다음으로 태도지표의 조절효과는 직무만족과 고객지향성, 직무만족과 이직의도 간의 관계 모두에서 유의한 것으로 나타났다. 본 연구는 MBTI 성격유형에 따른 직무만족과 고객지향성, 직무만족과 이직의도간의 관계에 존재하는 MBTI 성격유형의 조절효과를 검증함으로써 학문적 실무적 시사점을 제시하였으며, 직무만족을 통한 고객지향성 향상과 이직의도 감소노력에 있어 MBTI 성격유형을 고려한 맞춤전략을 수행할 수 있게 될 것으로 기대된다.

This study is aimed at interpreting into changes and characters of function applied into quantative analysis in ubiquitous house. Digital technology being introduced into architectural fields, It applied expansively from design and construction to user's convenience. The application of digital technology is presented to various change like effectiveness and exactness in design and function of space, which is overlayed digital space to physical space beyond the extent of receiving human needs in physical space. In ubiquitous house, digital technologies are supplied to function coordinated with life, appreciating into positional informations of human and materials, spatial informations. Ubiquitous house is comparably effective into funtional expansion, user's convenience, safty, which, for the future, is going to using on housing of high performance encouraging the application of advanced technology. Therefore this study is classified into human behaviors, functions, performances and characters of digital system in ubiquitous house, which being established into the relation of elements, is interpreted numerically into functional changes and charats being applied to ARM.

Generating functions play an important role in the investigation of various useful properties of the sequences which they generate. Exton [13] presented a very general double generating relation involving products of two Laguerre polynomials. Motivated essentially by Exton's derivation [13], the authors aim to show how one can obtain nineteen new generating relations associated with products of two Laguerre polynomials in the form of a single result. We also consider some interesting and potentially useful special cases of our main findings.

Structure-borne noise is the interior noise that results from the low frequency vibrational energy transmitted through those body and joint parts. The relation between the excitation of powertrain and resultant interior sound must be analyzed in order to identify and predict the structure borne noise. The method of acoustic source excitation is preferred than the method of mechanical force excitation to measure the NTF(noise transfer function). Because acoustical method is more convenient and reliable. In this paper, to analysis and identify vehicle interior noise by powertrain is performed, and the vibro-acoustic transfer function is extracted from experimental measurement. These are important step of TPA(transfer path analysis) to identify effect of interior noise resulted from powertrain running excitation.

An important problem to be carried into a plan on the occasion for introduction of TQC is to establish the clear-cut policy and workable system on QC. In connection with escalation the product liability in recent days, especially, a point to he considered in relation the real state of enterprise, it seems likely to be difficult an effective performance without distribution of the definite duality function to each departments in the company, and to define the quality function, it should be educed and coordinated under agreement organization wide participation and conciliation. In this paper, we have tried to have a more effective graft the European style QC on the oriental enterprise, by means of presenting a model that manages synthetically a way of deployment the fundamental factors affecting quality, and establishing the control subject in each function unit.

Up to now, the existing crack growth modelling has used a mathematical approximation but an assumed function have a great influence on this method. Especially, crack growth behavior that shows very strong nonlinearity needed complicated function which has difficulty in setting parameter of it. The main characteristics of neural network modelling to engineering field are simple calculations and absence of assumed function. In this paper, after discussing learning and generalization of neural networks, we performed crack growth modelling on the basis of above learning algorithms. J'-da/dt relation predicted by neural networks shows that test condition with unlearned data is simulated well within estimated mean error(5%).

The purpose of this study was to verify fitness of a new raglan sleeve pattern according to the result of appearance and function evaluation. Also, it was to search the relation between the construction factor and the function on the selected 3 types of the existent raglan sleeve patterns and the new sleeve pattern. Three female university students having different shoulder shapes were selected as subjects, wore 4 different types of the raglan steeve was evaluated by professional panel. The functions of the evaluated sleeve patterns evaluated was made by the wearer themselves. According to the comparison of the new raglan sleeve pattern with the existent raglan sleeve pattern, the new raglan sleeve pattern acquired the higher evaluation scores both on the appearance test and the function evaluation. It was known that the appearance and function of the raglan sleeve pattern were effected by construction factors of the sleeve pattern.

In this paper, a modified RBF(Radial Basis Function) network structure is suggested for the prediction of a time-series with non-linear, non-stationary characteristics. Coventional RBF network predicting time series by using past outputs sense the trajectory of the time series and react when there exists strong relation between input and hidden activation function's RBF center. But this response is highly sensitive to level and trend of time serieses. In order to overcome such dependencies, hidden activation functions are modified to react to the increments of input variable and multiplied by increment(or dectement) for prediction. When the suggested structure is applied to prediction of Macyey-Glass chaotic time series, Lorenz equation, and Rossler equation, improved performances are obtained.
