본 연구의 목적은 금융기관 종사자의 Big5 성격요인에 따른 창업의도를 밝히는데 있다. 또한 디지털미디어 활용 역량이라는 매개 변수가 창업의도에 어떠한 영향을 끼치는지 알아보고자 한다. 금융기관 중 제1 금융권에 재직중인 은행원으로 대상을 세분화하여 살펴볼 예정이다. 은행원의 창업의도에 관한 선행 연구가 적을 뿐만 아니라, 그 내용도 직장 내에서의 직무 만족이나 고용불안정에 따른 이직과 창업의도, 그리고 은퇴 후의 삶에 대한 논문이 다수이다. IT와 핀테크의 발달로 인해 은행의 구조조정은 꾸준히 진행되어 왔으며 앞으로도 지속적으로 실행되어질 것이다. 대상자의 확대로 정년과 상관없이 30대 이후의 모든 연령층에서 희망퇴직이 이루어지고 있는데, 30~40대의 희망퇴직자는 상당수 이직이나 창업에 뜻을 두고 있다. 은행원의 성격 특성을 분리하고 창업의 성장에 중요한 역할을 하고 있는 디지털미디어 활용역량을 분석하여 창업의도와 어떠한 관계가 있는지 살펴볼 예정이다. 은행원의 특성에 맞는 창업교육프로그램이 이루어진다면 창업의 성공적인 결과를 이루어내는데 기여할 것으로 예상된다.

최근 기후변동성으로 유발되는 불안정한 기상상태를 효과적으로 관측하고자 기상레이더가 도입되고 있다. 기상레이더는 경험식으로 산정된 Z-R 관계식을 통하여 레이더 강수량을 제시하게 된다. 이 과정에서 레이더 강수량은 필연적으로 실제 지상에 도달하는 강수량과는 정량적으로 오차가 발생하게 된다. 레이더 강수량에 포함된 오차는 다양한 원인으로 발생하게 되므로 레이더 강수량의 오차 성분을 규명하는 것은 레이더 강수량 활용을 위하여 필수적으로 선행되어야 한다. 본 연구는 지상강수량과 레이더 강수량의 편의를 보정하기 위한 확률통계학적 방법론을 개발하였다. 레이더 강수량의 편의오차를 보정하기 위하여 수문통계학에서 널리 활용되고 있는 계층적 Bayesian 구조를 기반으로 하였으며 자료통합(data pooling) 기법을 이용하여 편의보정 매개변수 추정과정의 불확실성 추정 효율성을 증대시켰다. 본 연구를 통하여 개발된 레이더 강수량 편의보정기법은 계층적 Bayesian 구조를 도입함으로써 편의보정 매개계수의 불확실성을 정량적으로 제시하였으며 유역 단위의 강수상관성을 현실적으로 복원하는 것을 확인하였다. 따라서 본 연구에서 제안하는 편의보정기법은 편의보정 과정에서 발생할 수 있는 매개변수의 불확실성 및 레이더 강수량의 오차구조를 정량적으로 규명하여 고해상도의 강수정보를 생산함으로써 고도화된 수문해석을 가능케 할 것으로 판단된다.

This study has investigated how attachment anxiety boosts the attitude on charity appeals. Drawing on the attachment theory, we tested the hypothesis that increasing attachment anxiety (both dispositionally and temporarily primed) would have favorable attitudes towards charity appeals relates to social identification. Participants in high attachment anxiety showed more favorable attitudes towards charity appeals which can fulfill their social needs. Needs for belongness mediated the relationship between charity appeals and attachment anxiety. While past research has focused on the attachment security as motivation for helping, The current study has focused on egoistic motivation for helping and examined that attachment insecurities leads more favorable attitudes towards charity appeals that fulfill their social needs. The current study demonstrates that social needs can motivate consumers' prosocial behavior. Implications for the theory of non-profit marketing are discussed.

The purpose of this study is to investigate the relationship between always being on call and the conflict factors between work and life balance among employees' in the IT relative industry. The results are as follows: always being on call factor perceived by employees' in the IT relative industry influences to conflict factor between work and life balance. Moreover, always being on call factor negatively effects on all factors of job insecurity which are impotent feeling and possibility of job loss. From the analysis of relation between job insecurity and conflict between life and work balance showed that the factor of impotent feeling influence on conflict between life and work balance while the factor of job loss does not. In addition, job insecurity(impotent feeling and possibility of job loss) partially mediated between always being on call and the conflict factors between work and life balance among employees' in the IT relative industry.

This study was conducted to investigate whether ego - resilience plays a mediating role in the relationship between adult attachment and job stress of fire officers, and to derive implications for job stress reduction of fire officers. A questionnaire survey was conducted for 480 fire officers working in Seoul and Gyeonggi - do, and correlation analysis and regression analysis were conducted using SPSS 21.0. The results showed that there was a negative correlation between instability attachment and job stress in adult attachment, negative correlation between instability attachment and ego - resilience in adult attachment, and negative correlation between ego - resilience and job stress. Adult attachment and ego - The results showed that there was a statistically significant effect on stress. Ego - resilience was found to full mediate the effect of anxiety of adult attachment on job stress and to partial mediate the effect of avoidance on job stress. This study suggests the need to develop a program that can improve ego - resilience considering the importance of ego - resilience and the occupational characteristics of fire officer. This means that the psychological and psychological factors of the individual should also be considered in order to reduce the level of job stress of the fire service personnel.

Recently, weather radar system has been widely used for effectively monitoring near real-time weather conditions. The radar rainfall estimates are generally relies on the Z-R equation that is an indirect approximation of the empirical relationship. In this regards, the bias in the radar rainfall estimates can be affected by spatial-temporal variations in the radar profile. This study evaluates the uncertainty of the Z-R relationship while considering the rainfall types in the process of estimating the parameters of the Z-R equation in the context of stochastic approach. The radar rainfall estimates based on the Bayesian inference technique appears to be effective in terms of reduction in bias for a given season. The derived Z-R equation using Bayesian model enables us to better represent the hydrological process in the rainfall-runoff model and provide a more reliable forecast.

In the current study, in order to understand the dynamic response characteristics of the system according to the external acoustic forcing, a numerical approach was developed by adding an sign-sweep forcing function to the existing network model. Through this model, the sensitivity of frequency and pressure amplitude changes according to system parameters such as the physical dimensions and boundary conditions of the target combustor was analyzed in a wide frequency range. Analysis results of dynamic response characteristics of the target combustor are shown that the frequency regime with high dynamic pressure response was similar to the instability frequency range measured in the same combustor, and in particular, the response of the system depends greatly on the location of the acoustic forcing source term.

This study illuminates the mechanism of life course on labor status of old age complementing the limits of labor status hypothesis of old age and model of statues attainment and combining them. The main results from this analysis are summarized in four points. Firstly, older men mostly engaged in agriculture, forestry and fishing industry or low-class occupations. A very small portion held high level or professional occupations. Regular full-time employees or employers were only 4.4% while, about 70% of older employees were temporal employees or self-employed. This shows that the elderly affluence hypothesis which alleges that most older men maintain high level occupations, applies to only a few. The second finding is that wealth differentials are sizable: about 20% of older workers own less than 50 million won, while 9.3% possess more than 600 million won. Therefore, it is not safe to claim that most people have accumulated enough wealth for old age according to the elderly affluence hypothesis. This gap being mainly reflected by education level, suggests that the model of status attainment is appropriate as wealth accumulation hypothesis. Thirdly, educational level determined not only lifetime careers, but also labor status of old age. Fourthly, using path analysis, the last finding is that education had effect on labor status of old age through lifetime career and wealth. That is, old men who have low education level had unstable lifetime career and own less wealth. They work in low income job, low social occupations and unstable occupation type in old age. This shows that life inequality continues until old age. Therefore, the inequality of education opportunity, spread of part-time work and small scale self employees should be discouraged. Furthermore, related policy should be provided in order to prevent being caught in unstable work.

This article presents the dynamic instability response of sigmoid functionally graded material plates on elastic foundation using the higher-order shear deformation theory. The higher-order shear deformation theory has ability to capture the quadratic variation of shear strain and consequently shear stress through the plate thickness. The governing equations are then written in the form of Mathieu-Hill equations and then Bolotin's method is employed to determine the instability regions. The boundaries of the instability regions are represented in the dynamic load and excitation frequency plane. The results of dynamic instability analysis of sigmoid functionally graded material plate are presented using the Navier's procedure to illustrate the effect of elastic foundation parameter on dynamic response. The relations between Winkler and Pasternak elastic foundation parameter are discussed by numerical results. Also, the effects of static load factor, power-law index and side-to-thickness ratio on dynamic instability analysis are investigated and discussed. In order to validate the present solutions, the reference solutions are used and discussed. The theoretical development as well as numerical solutions presented herein should serve as reference for the dynamic instability study of S-FGM plates.
