In this paper, we propose a system that collects data from sensors that detect the sleeping environment and adjusts the sleeping environment optimally based on the environment to help you get a good night's sleep. The sleep environment analysis is based on the determination of the sleep stage by detection of twisting through the load cell. In addition, based on data such as temperature, humidity, and illuminance, heat devices, humidifiers, blinds, etc. are controlled to create an environment in which to have a good sleep. The sleep environment control according to the sleep state can reduce fatigue when waking up by inducing a sleep state that is easy to wake up.

Fuzzy extractor is a biometric encryption that generates keys from biometric data where input values are not always the same due to the noisy data, and performs authentication securely without exposing biometric information. However, if a user registers biometric data on multiple servers, various attacks on helper data which is a public information used to extract keys during the authentication process of the fuzzy extractor can expose the keys. Therefore many studies have been conducted on reusable fuzzy extractors that are secure to register biometric data of the same person on multiple servers. But as the key length increases, the studies presented so far have gradually increased the number of key recovery processes, making it inefficient and difficult to utilize in security systems. In this paper, we design an efficient and reusable fuzzy extractor based on LWE with the same or similar number of times of the authentication process even if the key length is increased, and show that the proposed algorithm is reusably-secure defined by Apon et al.[5].

This study was to investigate the effects of interpersonal relationships on job satisfaction of home-visiting care helpers and the category of interpersonal relationships was subdivided into elderly clients, guardians, colleagues and directors considering the person-to-person nature of home-visiting care helper's job characteristics. A group of 336 care helpers who engaged in home-visiting care service providing facilities in Daejeon City was selected as a research subject, and the data were analyzed with SPSS 22.0 program using reliability, frequency, correlation and hierarchical multiple regression. The results for the final analysis revealed that the effect of socio-demographic features was not significant while, among characteristics of job performances, work priority, turnover experience, and career choice reasons turned out to have significant impacts on job satisfaction. In particular, interpersonal relationships except the one with guardians were found to be the most influential variables and the effects of those relationships on job satisfaction were significant. The influencing power was stronger in relationships with director, elderly clients, and colleagues in order, and the job satisfaction level was higher as they were in better relationships with director, elderly clients, and colleagues. The results of this research shows that it is necessary to set an atmosphere where harmonious interpersonal relationships can be formed inside and outside of facilities in order to improve job satisfaction of home-visiting care helpers.

Resveratrol is a naturally occurring stilbene which is safe and well-described compound with a potent anti-inflammatory activity. Recent studies suggested that resveratrol suppressed various inflammation mediated diseases such as asthma, chronic colitis, rheumatoid arthritis, and type 1 diabetes. These studies indicated that resveratrol might directly modulate $CD4^+$ helper T cells (Th cells)-mediated immune responses. However, it is not fully elucidated whether resveratrol directly regulates $CD4^+$ Th cell activation and differentiation. In the present study, $CD4^+$ Th cells were purified from C57BL/6 and treated with various concentrations of resveratrol. We found that resveratrol directly suppressed $CD4^+$ Th cells activation, leading to a defect in T cell proliferation. When $CD4^+$ Th cells were treated with resveratrol, cytokine production was also significantly reduced in a dose dependent manner. In accordance with these results, resveratrol even inhibited $CD4^+$ Th cells differentiation into Th1, Th2 or Th17, which produces IFN-${\gamma}$, IL-4 or IL-17 respectively. We also found that resveratrol could induce apoptosis of $CD4^+$ T cells at a high concentration. Our data demonstrated that resveratrol inhibited directly $CD4^+$ Th cells activation and differentiation. It suggests that resveratrol could be an efficient therapeutic strategy for autoimmune diseases in which $CD4^+$ Th cells play a critical role.

The purpose of this study is to investigate the relations between housewife's self esteem and attitude toward household work its satisfaction and to find out how independent variables(housewife's age, education level, employment, household work helper, type of family) have effect on the two dependent variables. The measurement of self-esteem was based on the self-concept test standarized by Jung Won Sick, reformed the Fitts measurement for Korean Society. In order to measure of attitude toward household work and its satisfaction, based on the previous research, researcher made the measurement . the research was conducted on 234 housewives in Seoul in September 1984. Data was analyzed by percentage, mean, frequence analysis of variances, Pearson's correlation coefficient. The result can be summarized as following. 1)Over on half of housewives have high self-esteem comparatively. 2) Age and education level were variables to have influence n the attitude toward household work. 3)The attitude toward household work and its satisfaction comparatively were high. 4)Education level and type of family were variables to have influence on the attitude toward household work. Education level, employment and household work helper were variables to have influence on the satisfaction of house hold work. 5) Level of Self-esteem has influence on the attitude toward household work and its satisfaction. The higher level of self-esteem was, the higher becomes the score of the attitude toward house hold work and its satisfaction. Following suggestions can be extracted form the results of above study. 1) research of housewife's self-esteem didn't established a setted theory yet. I think, therefore, it requires deeper study about housewife's household work look upon as her occupation and relation between the household work as her occupation and her self-esteem in this area. 2) Population and sociological variables, used in this study, hardly influenced on self-esteem, the attitude toward household work and its satisfaction. Also the result didn't correspond with one another. So I think it requires need of further study how psychological and family function variables will have influence on housewife's self-esteem, the attitude toward household work and its satisfaction. 3) To recognized the value of household work objectively, many researchers tried to investigate of economical value of household work, But if housewife can realize her self-actualization through household work, it requires the study that try to objectively not only estimate the economic value of household work, but also the contribution of the aspect of family psychology.

Atopic dermatitis (AD) is an immune disorder that is becoming increasingly prevalent throughout the world. The exact etiology of AD remains unknown, and a cure for AD is not currently available. The hypothesis that appropriate early microbial stimulation contributes to the establishment of a balanced immune system in terms of T helper type Th1, Th2, and regulatory T cell (Treg) responses has led to the use of probiotics for the prevention and treatment of AD in light of various human clinical studies and animal experiments. Meta-analysis data suggests that probiotics can alleviate the symptoms of AD in infants. The effects of balancing Th1/Th2 immunity and enhancing Treg activity via the interaction of probiotics with dendritic cells have been described in vitro and in animal models, although such an effect has not been demonstrated in human studies. In this review, we present some highlights of the immunomodulatory effects of probiotics in humans and animal studies with regard to their effects on the prevention of AD.
