The purpose of this study was to examine the relationships among dementia knowledge, empathy, attitudes toward to dementia in caregivers of older adults with dementia. Data were collected 147 caregivers who worked in long term care centers. The self-report questionnaire was used for data analysis. SPSS Win. 21.0 was used to analyze data via descriptive statistics, Pearson correlation coefficient, and multiple regression. The mean score of dementia knowledge was $20.18{\pm}3.58$ out of 30, and the means of empathy was $82.12{\pm}9.68$ out of 105 and the means of dementia attitudes was $96.45{\pm}13.72$ out of 140. Attitudes toward dementia in caregivers differed significantly depending on their age, motivation of job. Attitudes also had a positive correlation with dementia knowledge and empathy. The most significant preditors of attitudes were empathy, job of motivation and age. These factors explained 33.0% of the variance for attitudes toward dementia. Above results suggest that dementia education programs depending on age, job of motivation, and empathy level is needed.

This paper presents analog secure communication system about safe speech transmission using chaotic signals. We applied various conditions that happen in actuality communication environment modifying chaotic synchronization and chaotic communication schemes and analyzed restoration performance of speech signal to computer simulation. In transmitter, we made the chaotic masking signal which is added voice signal to chaotic signal using PC(Pecora ＆ Carroll) and SFB(self-feedback) control techniques and transmitted encryption signal to noisy communication channel And in order to calculate the degree of restoration performance, we proposed the definition of analog average power of recovered error signals in receiver chaotic system. The simulation results show that feedback control techniques can certify that restoration performance is superior to quantitative data than PC method about masking degree, susceptibility of parameters and channel noise. We experimentally computed the table of relation of parameter fluxion to restoration error rate which is applied the encryption key values to the chaotic secure communication.

This paper deals with the estimation method on the initial pole position of a z-axis permanent magnet linear synchronous motor(PMLSM) without magnetic pole sensors such as Hall sensors. The proposed method takes account of the gravitational force at z-axis and also the load conditions. The algorithm consists of two steps. The first step is to approximately estimate the initial q-axis by monitoring the movements due to the test current at predefined different test q-axes. The second step is to estimate the real q-axis as accurately as possible by using the outputs corresponding to torques due to the test current at three different test q-axes in order to avoid the effect of load mass variations. Experimental results on the z-axis PMLSM show good estimation characteristics of the proposed method irrespective of load mass conditions.

This article explores the characteristics of care and care labor which is core keyword of the welfare state and the way of institutionalization of care labor, focusing specially on differences among women. Caring is defined by the expression of morality and labor accompanied by concrete action. But, care labor in the welfare state is defined by "activities involved in caring for the ill, elderly, handicapped and dependent", and I think, that definition is more useful than the narrow one for policy institutionalization. But the latter definition intentionally separates the domestic work from care work. Care labor is considered to be different from the market labor in terms of motivations, but there are some limits in standardization and commercialization of the traits of emotional and moral engagement. Thus, requiring of emotional motivation as one of the job descriptions is not realistic. Welfare state is institutionalizing women's unpaid care work in family through de-familization, and its policy tools are cash benefits and services for care-related, which influence to the female wage worker and fulltime housewife, care receiver and care giver, and polarization of women's class in a very different way. Cash benefits enhances the division of gender labor, polarizes the care laborer and weakens of expansion the care as decent job. The movement of feminist welfare state have a vision of universal service expansion and need the policy list for de-gendering of care labor.

Obviating user churn is a prominent strategy to capitalize on online games, eluding the initial investments required for the development of another. Extant literature has examined factors that may induce user churn, mainly from perspectives of motives to play and game as a virtual society. However, such works largely dismiss the service aspects of online games. Dissatisfaction of user needs constitutes a crucial aspect for user churn, especially with online services where users expect a continuous improvement in service quality via software updates. Hence, we examine the relationship between a game's quality management and its user base. With text mining and survival analysis, we identify complaint factors that act as key predictors of user churn. Additionally, we find that enjoyment-related factors are greater threats to user base than usability-related ones. Furthermore, subsequent quasi-experiment shows that improvements in the complaint factors (i.e., via game patches) curb churn and foster user retention. Our results shed light on the responsive role of developers in retaining the user base of online games. Moreover, we provide practical insights for game operators, i.e., to identify and prioritize more perilous complaint factors in planning successive game patches.
