Given the limitations of UI benefit and self-insurance through precautionary savings, this paper suggests a new scheme of income support for the unemployed, which offers unemployed workers not only UI benefit but also borrowings from their future pension incomes. Allowing individuals to have effective self-insurance through pension- borrowing, this scheme provides them with consumption-smoothing and reduction in risk burden while maintaining search incentives of the unemployed. Simulation study based upon household panel data in Korea suggests that a heavy reliance should be set upon self-insurance through pension-borrowings rather than upon UI benefit, even for the low-income individuals who are subsidized under UI system. This result provides us with insightful implications for a social safety net in (fast-growing) developing countries, where people cannot afford a good amount of UI benefit or of precautionary savings against unemployment although they expect their incomes to be much higher in the future. Indeed, it is consumption-smoothing effect of self-insurance through pension- borrowings, as well as its incentive-maintaining effect, that makes it a promising alternative of social safety net in developing countries.

Purpose: The purpose of this study is to identify the mediating effects of self-esteem between social comparison orientation and social network service (SNS) addiction in university students. Methods: Descriptive cross-sectional survey design was employed. The data were statistically analyzed by using the descriptive and inferential statistics. Sobel test and Bootstrap method, and Kappa squared mediation effect size measure were used to identify the mediator's significance. A convenience sample of 195 subjects was recruited from two universities in Korea. Results: The mean age of the subjects was $22.58{\pm}1.81$. The subjects showed relatively high levels of SNS addiction with a mean score of $14.33{\pm}4.80$. The overall model significantly explained 37.0% of variances in the subjects' SNS addiction after controlling gender, age, grade, major, period of SNS using, time spent on SNS per day, and times accessed SNS per day. Of the predictors, time spent on SNS per day, social comparison orientation, and self-esteem were significantly associated with SNS addiction. Self-esteem was the mediator between social comparison orientation and SNS addiction. Conclusion: When developing strategies for preventing SNS addiction, interventions for reducing time spent on SNS per day, not having upward social comparison orientation, and improving the self-esteem should be considered. These findings might provide a theoretical basis for developing effective strategies for preventing SNS addiction in university students.

The multi-layered and compartmented hydrogel was designed to examine the self-transforming for developing a 4D mask pack. The hydrogel consisting of two layers with different expansion ratios were fabricated to have specific curvature by self-folding assembly. In addition, the hydrogel compartmented with three different geometries was designed by varying of expansion ratios. The compartmented hydrogel with 0.03, 0. $0,03mm^{-1}$ of curvatures at room temperature was self-transformed with 1.33, 0, $1.33mm^{-1}$of curvatures at $37^{\circ}C$, enhancing the facial adhesion. Overall, this new strategy to prepare the multi-layered and compartmented hydrogel would be actively used in developing the 4D mask pack to self-transform by each facial curvature.

Purpose: The purpose of this study was to investigate the effects of self-directed learning ability and creativity on college adjustment in nursing students. Method: Data were collected by questionnaires from 148 nursing students in October, 2010. Collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficient and stepwise multiple regression. Results: A positive correlation was found for college adjustment with self-directed learning ability and creativity. Self-directed learning ability and major satisfaction were significant predictors of college adjustment. The model explained 44.1% of the valuables. Conclusion: The results of this study suggest that self-directed learning be considered when developing strategies to increase college adjustment in nursing students.

A novel self-reference sense amplifier with parallel reading during writing operation is proposed. Read access time is improved compared to conventional self-reference scheme with fast operation speed by reducing operation steps to 1 for read operation cycle using parallel reading scheme, while large sense margin competitive to conventional destructive scheme is obtained by using self-reference scheme. The simulation was performed using standard $0.18{\mu}m$ CMOS process. The proposed self-reference sense amplifier improved not only the operation speed of less than 20 ns which is comparable to non-destructive sense amplifier, but also sense margin over 150 mV which is larger than conventional sensing schemes. The proposed scheme is expected to be very helpful for engineers for developing MRAM technology.

This study aimed to explore the effect of college students' self-leadership and entrepreneurship on employment competency and identify the moderating effect of nationality. To this end, the validity of data collected from 450 college students attending a four-year university in Seoul was tested using structural equation modeling and AMOS statistical software. The study showed the following results. First, self-leadership was found to have a significant effect on entrepreneurship. Second, entrepreneurship was found to have a significantly positive effect on employment competency. Third, it was found that nationality exerted a partial effect on the relationship of self-leadership and entrepreneurship to employment competency. Based on these findings, this study indicated that developing college student's employment competency through self-leadership and entrepreneurship training according to their nationality can help resolve the severe employment crisis in the age of the fourth industry.

Sub-optimal participation is a major problem with cervical cancer screening in developing countries which have no organized national screening program. There are various notable factors such as 'embarrassment', 'discomfort' and 'no time' cited by women as they are often also the bread winners for the family. Implementation of self-sampling methods may increase their participation. The aim of this article was to provide a survey of various types of self-sampling tools which are commonly used in collection of cervical cells. We reviewed currently available self-sampling devices and collated the advantages and disadvantages of each in terms of its acceptance and its accuracy in giving desired results. In general, regardless of which device is used, self-sampling for cervical scrapings is highly acceptable to women in most of the studies cited.

Turbulent boundary layer noise is already a significant contributor to sonar self noise. For developing acoustic window of sonar system to reduce self noise, a parametric study of design factors of acoustic window is presented. Distance of sensor array from acoustic window, material and damping layer are studied as design factors to influence in the characteristics of the transfer function of self noise. As the result these design factors make change the characteristics of transfer function slightly. Among design factors the location of sensor array is most important parameter in the self noise reduction.

The aims of this study were to investigate the effects of self-efficacy on adolescents' school adjustments and to identify mediating effects of depression and aggression. To this end, we conducted descriptive analysis, correlation analysis, and path analysis, using data from the 2008 Korean Youth Panel Survey undertaken by the National Youth Policy Institute. Our analysis shows that self-efficacy has positive effects on adolescents' school adjustments, while both depression and aggression have negative effects on adolescents' school adjustments. Moreover, both depression and aggression have a mediating effect when it comes to self-efficacy and school adjustments. These results imply that schools should consider developing a service delivery system by providing students with professional services that enhance self-efficacy. Moreover, such services will be more effective when they are combined with a program that reduces students' depression and aggression.
