This study examined the interdependent retirement decision between husbands and wives. Since most of retirees in Korea retired by involuntary reasons such as health problems, it purposes to test whether the involuntary retirement of husbands(wives) influences the retirement decision of wives(husbands). Using data from 4th Korean Longitudinal Study of Ageing Panel, it conducted probit and multivariate probit analysis on 1,038 dual-earner couples aged 51~76 to test interdependence of couples' retirement. The results showed that husbands who have retired wife were more likely to retire. It also proved that involuntary retirement of spouse is a significant predictor of early retirement decision, though the direction of the effect is reversed by gender. Wives were more likely to retire when husband were retired involuntarily, while husbands were more likely to stay in labor market. These findings helped to understand the retirement decision of aged couples in Korea and brought suggestion on labor market and care policies for aged couples.

This study investigates the influential factors for the user's satisfaction in usage of PDA in Korea Postal Services. This is the case of user's acceptance of information technology that organization mandatorily implements for the sake of employee's productivity. The factors examined in this study include system quality, information quality, perceived usefulness, user satisfaction, and compatibility with work. All these factors were found significant for users satisfaction. Especially, we notice the close relationship between compatibility with work, perceived usefulness, and user satisfaction in case of nonvolitional IT usage.

This study examines job transition process and its lahor market performance by reasons of job separation, using the Employment Insurance DB(2000~07). The findings show that involuntary job changers lend to suffer greater loss in job spell and real wage than voluntary job changers, which seems to reflect their characteristics such as lower quality of job matching due to unsystematic job search, negative signaling effect in the labor market and decreasing availability of human capital in previous job. In addition, unemployment benefit eligible for involuntary job changers tends to prolong the period of unemployment, while increasing job spell in the following employment.

Autoignited lifted flames in laminar jets with hydrogen-enriched methane fuels have been investigated experimentally in heated coflow air. The results showed that the autoignited lifted flame of the methane/hydrogen mixture, which had an initial temperature over 920 K, the threshold temperature for autoignition in methane jets, exhibited features typical of either a tribrachial edge or mild combustion depending on fuel mole fraction and the liftoff height increased with jet velocity. The liftoff height in the hydrogen-assisted autoignition regime was dependent on the square of the adiabatic ignition delay time for the addition of small amounts of hydrogen, as was the case for pure methane jets. When the initial temperature was below 920 K, where the methane fuel did not show autoignition behavior, the flame was autoignited by the addition of hydrogen, which is an ignition improver. The liftoff height demonstrated a unique feature in that it decreased nonlinearly as the jet velocity increased. The differential diffusion of hydrogen is expected to play a crucial role in the decrease in the liftoff height with increasing jet velocity.

To describe mathematics learning relying on a priori assumptions about the learners has a risk of assuming the learners as well-prepared subjects. In this study we investigate the epistemological perspective of Gilles Deleuze which is expected to give overcome this risk. Then we analyze the constructivist's epistemology and prior discussions about learning mathematics in the preceding studies accordingly. As a result, a priori assumption on which students are regarded as well-prepared for learning mathematics is reconsidered and we propose a new model of thought to highlight the involuntary aspect of the occurrence of thinking facilitated by the encounter with mathematical signs. This perspective gives a new vision on involuntary aspects of mathematics learning and the learner's confusion or difficulty at the starting point of learning.

Businesses recognize the importance of empathy among members for achieving organizational goals. Accordingly, they have developed and implemented communication programs aimed at enhancing mutual understanding between the MZ generation and the older generation. However, recent communication programs conducted by businesses differ in that they involve compulsory participation driven by the organization. This study sought to empirically examine their effectiveness. Data was collected from 697 participants in communication programs to validate the proposed research model, which was empirically tested through regression analysis. The results of the analysis confirmed the effectiveness of communication programs even in non-voluntary situations and highlighted intergenerational perception differences. The findings of this study emphasize the significant role of communication and empathy within organizations. Consequently, they have impacted the development of communication strategies and culture within organizations, and are expected to provide theoretical and practical insights valuable to researchers and practitioners interested in intergenerational perception differences from a knowledge management perspective.

본 연구는 은퇴 후 신체적 건강이 시간이 지남에 따라 어떤 변화양상을 나타내는지, 은퇴 후 신체적 건강에 영향을 주는 것으로 알려진 은퇴 특성(은퇴시점, 은퇴자발성 여부) 변인이 은퇴 후 신체적 건강의 궤적에 어떠한 영향을 미치는지를 분석하고자 하는 목적으로 실시되었다. 분석 자료는 국민노후보장패널 3차시(2009년), 4차시(2011년), 5차시(2013년) 종단자료이며, 2,857명을 대상으로 잠재성장모형 분석을 실시하였다. 연구결과, 첫째, 중 고령은퇴자의 신체적 건강은 시간의 흐름의 변화를 알아보기 위해 무조건부 모형을 통해 확인한 결과, 중 고령은퇴자들은 시간이 지남에 따라 더 높은 수준의 ADL 값을 갖는 것으로 나타났다. 둘째, 중 고령은퇴자의 신체적 건강변화와 관련이 있는 은퇴특성은 무엇인지 조건부 모형을 통해 알아본 결과, 은퇴 특성 변수로는 조기은퇴자일 때, 은퇴가 비자발적일 때, 건강상 이유로 은퇴했을 때 더 높은 ADL 초기값을 보였다. 또한 변화궤적 영향요인을 살펴본 결과, 은퇴특성에서는 어떤 변수도 유의성을 보이지 않았고, 인구사회학적 변수 중에서는 연령이 높을수록, 소득이 높을수록 ADL의 증가속도가 더욱 가파른 것으로 나타났다.

This research explores the factors affecting infusion of public administrative information systems(IS) and analyzes its impact on work performance. For this purpose, the factors affecting the infusion of IS are classified into voluntary and involuntary motivations based on the self-determination theory that explains individual motivations. As factors for voluntary motivation, performance expectancy, personal innovativeness, and organizational citizenship behavior are proposed, while government influence, competitor influence, and the top-level management influence are proposed as factors for involuntary motivation. The analysis shows the voluntary motivation factors-performance expectancy, personal innovativeness, and organizational citizenship behavior-do affect infusion of IS, whereas the involuntary motivation factors-government influence, competitor influence, and the top-level management influence-have no statistically significant impact on the infusion of IS. The relationship between infusion of IS and work performance is found significant. While individuals are unable to decide on the adoption of IS in an involuntary environment such as in the case of using the public administrative IS, the results show that the factors related to individual autonomy have an important role in extended, active usage of IS beyond the mandatory level.

This exploratory study examined the possibility that the notion, willing suspension of disbelief, can explain the processing of animated spokes-character in advertising. Willing suspension of disbelief has originated from Coleridge's explanation of poetic faith. And the term has been theoretically studied in the response of fiction in creative works, such as cinema, dramas, and advertisements, as well as literature. So far, willing suspension of disbelief has been proposed as a mediator of empathy, cognitive responses and affective responses to fiction. On these theoretical bases, a survey was conducted to 64 people with 3 advertisements to test the validity of the discriminant function. Findings of discriminant function analysis are as follows: First, the variable of willing suspension of disbelief well discriminated between the willing group and the non-willing group. Secondly, the Intensity of willing suspension of disbelief showed statistically significant difference between the willing group and the non-willing group. Thus, according to these results, it is proposed that the effects of the willing suspension of disbelief can be examined as a mediator of the response of fiction in further substantial studios.
