It is very difficult, but important, to induce and maintain voluntary user engagement in content. For example, many Internet contents provide financial rewards for the user's participation and maintenance. However, there are limitations to methods such as stimulating only external motivations, such as monetary rewards, and sophisticated design and management are needed to obtain sustained and voluntary user participation in content. For this purpose, we propose a Gamified CMS that extends the existing Content Management System (CMS) by referring to the example of the Gamified Learning Management System. This will ultimately increase the participation and commitment of users in content.

In this paper, we investigate a market equilibrium in multi-channel sharing cognitive radio networks (CRNs): it is assumed that every subchannel is orthogonally licensed to a single primary user (PU), and can be shared with multiple secondary users (SUs). We model this sharing as a spectrum market where PUs offer SUs their subchannels with limiting the interference from SUs; the SUs purchase the right to transmit over the subchannels while observing the interference limits set by the PUs and their budget constraints. The utility function of SU is defined as least achievable transmission rate, and that of PU is given by the net profit. We define a market equilibrium in the context of extended Fisher model, and show that the equilibrium is yielded by solving an optimization problem, Eisenberg-Gale convex program.

Rewards or penalties become informative only when contingent on an immediately preceding response. Our goal was to determine if the brain responds differently to motivational events depending on whether they provide feedback with the contingencies effective for learning. Event-related fMRI data were obtained from 22 volunteers performing a visuomotor categorical task. In learning-condition trials, participants learned by trial and error to make left or right responses to letter cues (16 consonants). Monetary rewards (+500) or penalties (-500) were given as feedback (learning feedback). In random-condition trials, cues (4 vowels) appeared right or left of the display center, and participants were instructed to respond with the appropriate hand. However, rewards or penalties (random feedback) were given randomly (50/50%) regardless of the correctness of response. Feedback-associated BOLD responses were analyzed with ANOVA [trial type (learning vs. random) x feedback type (reward vs. penalty)] using SPM8 (voxel-wise FWE p < .001). The right caudate nucleus and right cerebellum showed activation, whereas the left parahippocampus and other regions as the default mode network showed deactivation, both greater for learning trials than random trials. Activations associated with reward feedback did not differ between the two trial types for any brain region. For penalty, both learning-penalty and random-penalty enhanced activity in the left insular cortex, but not the right. The left insula, however, as well as the left dorsolateral prefrontal cortex and dorsomedial prefrontal cortex/dorsal anterior cingulate cortex, showed much greater responses for learning-penalty than for random-penalty. These findings suggest that learning-penalty plays a critical role in learning, unlike rewards or random-penalty, probably not only due to its evoking of aversive emotional responses, but also because of error-detection processing, either of which might lead to changes in planning or strategy.

Effects of job stress and drinking motivations on the drinking behavior of Korea's mentally challenged in sheltered employment. The purpose of this article was to investigate job stress, drinking motivations, and factors influencing the drinking behavior of Korea's mentally challenged. The 97 subjects' average job stress level was slightly below average. The subjects were found to experience salary-related stress the most out of the five sub-areas of job stress. The strongest motivations of drinking was the social motivation. In terms of drinking behavior, the most common drinking frequency was 3-4 times a year. The most common drinking amount was two 500cc mugs of beer. The significant predictors to explain the variance of the frequency of drinking was motivations to cope with, age, and salary-related stress. The mentally challenged drink more often when they have coping motivations and salary-related stress, and when they are younger. The significant predictors to explain the variance of the amount of drinking was motivations to emotional uplifting, drinking colleagues, stress from role overload. The mentally challenged drink more when they have motivations to emotionally uplift themselves and less role overload-related stress and as they drink alone.

국내 굴지의 금융 기관들이 해킹에 따른 전산 사고 등으로 홍역을 치르고 있다. 특히 고객 정보가 유출되거나 멸실된 경우는 상당액의 금전적 보상도 따를 것으로 보아 회사의 손해도 만만치 않을 것이다. 더 큰 문제는 고객들의 불신에 따른 기업 이미지 손상이다. 이것은 돈으로 환산할 수 없는 가치로 오랜 기간 악 영향을 끼칠 수밖에 없다. 우리 협회 회원사의 경우 개인 고객의 정보를 직접 취급하는 일이 거의 없어 걱정이 덜되지만 대부분의 기업 정보가 전산으로 처리되고 있는 만큼 그 보안 상태를 점검해 볼 필요가 있다.

This study analyzed the effects of Employee Value Proposition (EVP) and the impotance of a job rotation system on the subjective career success. The total 379 samples were surveyed from employees engaging in domestic hotel enterprises located in Seoul using convenient sampling method. The result of this research is as followings. First, EVP has total 5 factors('career development,' 'affiliation,' 'work environment,' 'work content' and 'pay & reward') and job rotation has total 3 factors('individual capacity improvement,' 'procedural justice,' and 'career development'). Second, the results of hypotheses test using a series of multiple regression analysis indicate that EVP factors including 'career development,' 'affiliation,' 'work environment,' and 'work content' influence subjective career success. However, EVP factor of 'pay & reward' does not influence subjective career success. Similarly, EVP factors excluding 'pay & reward' affect a job rotation system. Lastly, a job rotation system positively affects subjective career success. Based on the analysis results, we could draw the importance of the non-financial reward instead of financial reward in the perception of employees' subjective career success. As a research implication, the importance of the creative organization culture was suggested in the conclusion section.

The primary aim of this study is to examine difference in psychological well-being (PWB) and family support and explore its factors by the types of productive activity: paid labor, voluntary activity, or caregiving for their grandchildren. Three hundred females aged over 60 currently participating in productive activities were interviewed. The main results are as follow. First, PWB of volunteers is higher than any other group. Second, level of support provided by family members is highest for the group of grandchildren caregiving. Third, the variables affecting PWB for paid workers are educational level and material reward. As for the volunteers, PWB is explained by satisfaction with the given activity and instrumental support of their family members on it. PWB of grandchildren caregivers is explained by their marital status, income, material reward, emotional and instrumental support.

We examined the effect of delayed and immediate rewards on short- and long-term memory performance depending on the level of stress. It has been demonstrated that delaying feedback during memory tasks could lead to better retention than presenting it immediately (a.k.a., feedback delay benefit or delay-retention effect). In this study, we manipulated stress level(high-stress or low-stress), reward-timing(delayed or immediate reward), reward-existence(500 or 0 won) and retrieval-timing(delayed or immediate memory test). On the high-stress learning condition, one week later, the number of correct answers with delayed-rewards were significantly more than that of delayed-no-rewards but there was not any difference between immediate-rewards and immediate-no-rewards. On the other hand, in the high-stressful immediate memory test, immediate-rewards only had a positive effect on memory performance. The results indicated that delayed rewards improved long-term memory performance by promoting memory consolidation and the sensitivity to rewards was higher under the high-stress condition.

When any investment dispute arises, the investor has to exhaust the local remedies available in the host state, and according to the agreement between the parties, the investor is filed to the ICSID arbitral tribunal to seek arbitral awards. At this time, if the arbitral tribunal decides that the investment agreement has been violated, it normally demands the host state to provide financial compensations to the investor for economic loss. According to the rules of the investment agreement, the host state is supposed to fulfill the arbitral awards voluntarily. If it is unwilling to provide financial compensations according to the arbitral awards, however, the investor may ask the domestic court of the host state for the recognition and enforcement of arbitral awards. In addition, if the host state is unwilling to fulfill arbitral awards on account of state immunity, the investor may ask his own country (state of nationality) for diplomatic protection and urge it to demand the fulfillment of arbitral awards. Effectiveness for pecuniary damages, a means to solve problems arising in the enforcement of investment arbitral awards, is found to be rather ineffective. For such cases, this study suggests an alternative to demand either a restitution of property or a corrections of violated measures subject to arbitral awards.

The purpose of this study is to identify the relationship between the entrepreneurship of undergraduate students and the entrepreneurial intention focused on the mediating effect of the motivation for participating in the start-up idea contest. The results of the study were as followed; First, it was found that the factors of innovativeness, proactiveness and risk-taking in the entrepreneurship had significant influence on the entrepreneurial intention. Second, the effect of the factors between the innovativeness in the entrepreneurship and the entrepreneurial intention was significant influence by mediating effect of the motivation for participating in the start-up idea contest. Last, the factors of financial reward, career reward of the motivation were not effected by entrepreneurship and entrepreneurial intention. Based on these findings, students with high entrepreneurship have high entrepreneurial intention. And students were intended to feel a sense of achievement through challenging than getting financial rewards and career rewards. Therefore, it was shown that in order to encourage undergraduate's establish of a new business, the environment to develop innovative ideas and inspiring the confidence of participating in the start-up contest are needed to be invigorated.
