We examine the self-control problems of U.S households and their effects on households' retirement preparedness based on the Behavioral Life-Cycle Hypothesis. Using the 2010 Survey of Consumer Finances dataset, the level of retirement adequacy was estimated with income replacement ratio (IRR), and only 42% of households were adequately prepared for retirement. Results from logistic regression analysis indicated that households with loan payment and saving self-control problems were less likely to be prepared adequately for retirement compared to those without such problems. Age, education, race/ethnicity, marital status, employment status, retirement plans, expected retirement age and risk tolerance were significantly related to retirement preparedness. This study provides financial educator and researchers with suggestions on how to help household make a better retirement plan.

The self-assembled formation of octadecanethiol (CH3(CH2)17SH) on a gold substrate was studied using a quartz crystal microbalance (QCM) and a scanning tunneling microscope (STM). From the QCM measurements at vario us concentrations of octadecanethiol solutions in hexane and alcohol, the adsorption process of octadecanethiol onto Au was confirmed to consist of two steps as follows: (i) fast but disordered adsorption and (ii) a thermodynamically controlled rearrangement for uniform packing of octadecanethiol. Also, it was revealed that the adsorption rate became faster in ethanol than in hexane since less solubility of octadecanethiol in ethanol could help the formation of the monolayers. At 5 ${\times}$10-7 M solution, the monolayer formation was monitored by STM. The morphology of monolayer region was initially circular (diameter size: 7.26 $\pm$ 2.1 nm) and gradually changed to a stripe type after several minutes. At higher concentration, the self-assembled monolayer was formed immediately after the solution was introduced to a substrate.

Instructional contents are used to demonstrate a technical process to teach and walkthrough certain procedures to carry out a task. This type of informational content is widely used for teaching and lectures in form of tutorial videos and training videos. Since there are questions and uncertainties for what could be the killer application for the novel wearables, we propose a self-instruction training application on a smart glass to utilize already-available instruction videos as well as public open data in creative ways. We design and implement a prototype application to help users train by wearing smart glasses specifically designed for two concrete and hand-constrained use cases where the user's hands need to be free to operate. To increase the efficiency and feasibility of the self-instruction training, we contribute to the development of a wearable killer application by integrating a voice-based user interface using speech recognizer, public open data APIs, and timestamp-based procedural content navigation structure into our proof-of-concept application.

Secondary neurulation (SN) is a critical process to form the neural tube in the posterior region of the body including the tail. SN is distinct from the anteriorly occurring primary neurulation (PN); whereas the PN proceeds by folding an epithelial neural plate, SN precursors arise from a specified epiblast by epithelial-to-mesenchymal transition (EMT), and undergo self-renewal in the tail bud. They finally differentiate into the neural tube through mesenchymal-to-epithelial transition (MET). We here overview recent progresses in the studies of SN with a particular focus on the regulation of cell lineage, self-renewal, and EMT/MET. Cellular mechanisms underlying SN help to understand the functional diversity of the tail in vertebrates.

Purpose: The purpose of this descriptive, cross-sectional study was to examine relationships among emotional labor, self-efficacy, and burnout of employees in public health centers. Factors that influence burnout of workers were also assessed. Methods: One hundred sixty six workers in public health centers completed a pack of self-report questionnaires. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA along with $Scheff{\acute{e}}$ test, and stepwise multiple regression. Results: Employees in public health centers seemed to experience emotional labor to some extent. There were statistically significant differences in burnout depending on the age of workers. Employees' burnout had a positive relationship with emotional labor and a negative relationship with self-efficacy. Factors influencing burnout of employees in public health centers were emotional dissonance, surveillance & monitoring of organization, age, and self-efficacy. Conclusion: Considering the findings from this study, health care providers need to develop effective interventions which increase the level of self-efficacy and decrease certain types of emotional labor for employees in public health centers and to help them effectively manage burnout.

As the society has been capitalized, the importance of money has appeared widely. And there are many problems caused from the lack of money is supposed rather a qualitative problem happened by mismanagement of money than a quantitative. The purposes of this study are to suggest the desirable direction in money management education to adolescents and to provide some basic data to resolve the juvenile delin-quency caused from lack of money. With this purposes this study dealt with the money management behavior of adolescents with reference to self-concept, which was considered one of the influential factors to the money management behavior. Questionnaires composed with the Self-concept test (developed by Dr. chung) and the Money management test (developed by Dr. Troelstrup) were distributed to 300 high school students. 180 of them was taken as data. mean score and F-ratio were applied as statistical methods. As result, significant difference in money management behavior between the groups divided by self-concept scores were found. The higher the self-concept score is, the more desirable the money management behavior is. Here we cannclude as follow; As the money management behavior of adolescents differs with reference to the self-concept, it is possible to help the adolescents 세 develop the money management by inspiring the self-concept. And money management training as a consumer education is needed by all means at home, because it has an important effect upon the identity establishment, the major developmental task in adolescence.

Objectives: The aim of this study was to explore the influence of learning social integration and self-doubt on the suicidal ideation, and to test the mediating effect of self-doubt and the moderating effect of drinking on suicidal ideation. Methods: A cross-sectional survey was administered to a convenience sample of 1,000 freshmen in a university in S city. A total of 803 questionnaires were included in the statistical analysis. To analysed the data, Pearson correlation and structural equation modeling were performed. Results: In this study, self-doubt had a mediating effects in the path way from learning social integration to suicidal ideation. Drinking had a moderating effect between self-doubt and suicidal ideation. Conclusions: The results suggest that the low level of learning social integration increases the level of self-doubt and leads to suicidal ideation. Drinking was a significant moderator of suicidal ideation. Therefore, interventions on various strategies to enhance academic performance and social interaction skill, and to help to stop or not to initiate drinking habit are needed in the early part of the freshman year.
