New social risks is likely to emerge from instability of family structure, flexible of labor market, movement of globalization which is related with the post-industrial society and so on. Especially, a lot of women are exposure to not only old social risks but also new social risks. A breakdown of traditional family structure, flexible of labor market which is be followed by globalization, women's poverty and limited approaches at social security services are the representation risk which is confront to women. In this study, therefore, the social risk is recognized by breakdown of traditional family structure risk which comes from the social change, aging of population, the decrease of labor population and New Right ideology. The purpose of the study is to arrange the new welfare state at gender equality level by anglicizing about women's new social risks.

For the simultaneous measurement of strain and damage signal a fiber Bragg grating sensor system with a dual demodulator was proposed. The dual demodulator is composed of a demodulator using a tunable Fabry-Perot filter measuring the low-frequency signal with large magnitude such as strain and the other using a passive Mach-Zehnder interferometer detecting the high-frequency signal with small amplitude such as impact or damage signal. Using the proposed fiber Bragg grating sensor system, both the strain and damage signals of a cross-ply laminated composite beam under tensile loading were simultaneously measured. The strain and damage signals detected by single fiber Bragg grating sensor showed that sudden strain shifts were accompanied with vibration at a maximum frequency of several hundreds of kilohertz at the instant of matrix crack propagation in the 90 degree layer in composite beam.

For the simultaneous measurement of strain and damage signal, a fiber Bragg grating sensor system with a dual demodulator was proposed. One demodulator using a tunable Fabry-Perot filter can measure low-frequency signal such as strain and the other demodulator using a passive Mach-Zehnder interferometer can detect high-frequency signal such as damage signal or impact signal. Using a proposed fiber Bragg grating sensor system, both the strain and damage signal of a cross-ply laminated composite beam under tensile loading were simultaneously measured. Analysis of the strain and damage signals detected by single fiber Bragg grating sensor showed that sudden strain shifts were induced due to transverse crack propagation in the 90 degree layer of composite beam and vibration with a maximum frequency of several hundreds of kilohertz was generated.

Objective : This study aimed to examine the association Self-Rated Health(hereafter SRH) and Activities of Daily Living(hereafter ADL), Independent Activities of Daily Living(hereafter IADL) among Korean elderly. Methods : Using nationally representative cross sectional studies called 2014 Survey of living conditions and welfare needs of Korean elder persons. We used SRH as an independent variable, disabilities of ADL and IADL as dependent variables. Logistic regression was implemented and potential confounders such as socio-economic status, demographic characteristics and others were adjusted. Results : It was revealed that people who were female(than male) and 75 or more years old(than less than 75 years old) were shown to have poor SRH and disabilities of both ADL and IADL. In logistic regression model, poor SRH was associated with ADL and IADL disabilities. Especially, their association was more remarkable among male than among female. It can be understood that socio-economic contexts affect quality of life among elderly and SRH can be differently perceived by gender. Conclusions : Our notable findings showed that gender perspective is needed to understand SRH and daily living among elderly.

Background: Catastrophic health expenditure (CHE) occurs when medical expenditure of a household passes over a certain ratio of household income. This research studied the effect of gender on CHE based on Korea Health Panel data. Methods: This study implemented binary logistic regression model to figure out whether gender affects CHE and how different gender groups show pattern of CHE process. With gender, age, marital status, income level, economic activity, membership of private insurance, existence of chronic disease, and self-rated health were included in the model. Results: Results showed that females faced CHE 1.5 times more than males (odds ratio, 1.241). Also, main determinants of CHE in female groups were marital status, while age and economic activity status were significant in male groups. Subgroup analysis displayed that married female under 35 years old are located in intersectionality of CHE including pregnancy and delivery, multiple health risk behaviors, mental stress, and relatively vulnerable social status due to lower income. Meanwhile, both gender above 50 years old faced remarkably high chance of CHE, which seems to be caused by complex health risk behaviors and chronic diseases. Conclusion: Such results implied not only that gender is an important determinant of CHE, but also other determinants of CHE differ according to gender, which suggests a necessity of gender-based CHE support and rescue policy.

This study analyzed the Internet consumption behavior concerning pet care through in-depth interviews with 11 people who take care of pets. In this study, along with owners of domestic companion animals, stray cat caregivers were included as pet consumers, which have not yet been included in this category in existing research. Internet consumption was found to differ between people with dogs and people with cats. In the case of dog owners, they bought a lot of bath products, clothes harnesses, and strollers that were not appropriate for cats. Although the pet-poor phenomenon is known to occur a lot among young consumers, who care for pets behavior at the cost of money spent on themselves, even stray cat caregivers, mostly middle-aged women, are wary of becoming pet-poor. It cannot be said that there are gender differences in online shopping of pet consumers. In general, women, who did mainly Internet shopping, and if they are not used to using the Internet, their husbands made purchases online instead.

The study examines the research trends of doctoral dissertations in Library Science and Information Science published in the U.S. for the last 5 years. Data collected from PQDT Global includes 1,016 doctoral dissertations containing "Library Science" or "Information Science" as subject headings, and keywords extracted from those dissertations were used for a network analysis, which helps identifying the intellectual structure of the dissertations. Also, the analysis using 103 subject heading keywords resulted in various centrality measures, including triangle betweenness centrality and nearest neighbor centrality, as well as 26 clusters of associated subject headings. The most frequently studied subjects include computer-related subjects, education-related subjects, and communication-related subjects, and a cluster with information science as the most central subject contains most of the computer-related keywords, while a cluster with library science as the most central subject contains many of the education-related keywords. Other related subjects include various user groups for user studies, and subjects related to information systems such as management, economics, geography, and biomedical engineering.

Electro-optical sigma-delta modulators are the core module of digital receiver to digitize wideband radio-frequency signals directly at an antenna. Electro-optical sigma-delta modulators use a pulsed laser to oversample an input radio-frequency signals at two Mach-Zehnder Interferometer(MZI) and shape the quantization noise using a fiber-lattice accumulator. Decimation filtering is applied to the quantizer output to construct the input signal with high resolution. The jitter affects greatly on reconstructing the original input signal of modulator. This paper analyzes the performance of first order single bit electro-optical sigma-delta modulator in the time domain and the frequency domain. The performance of modulator is analyzed by using asynchronous spectral averaging of the reconstructed signal's spectrum in the frequency domain. The reference value of time jitter is presented by analyzing the performance of jitter effects. This kind of jitter value can be used as a reference value on the design of modulators.

The purpose of this study was to analyze representations of fatherhood of childcare entertainment reality programs. For this purpose, two episodes of of MBC were analyzed by semiotic analytic methods, especially, signs, images, combined level of significations, etc. The results indicated that fathers of the programs reflected modern ideal images of feminist fatherhood in which fathers cooperated to care children with mothers, and played the role of intimate friend-daddies, daddies as friends. A post-modern male ideology was inherent in those fatherhood changes. Those fathers in this program intermittently exposed narratives of inexperienced fathers while dedicating themselves to cooperative childcare adequate to the purpose of the program, suggesting that it would reproduce the mother-childcare ideology as a result. Furthermore, although such reflected changes towards fatherhood enthusiastically involving in childcare represented the modern ideal fatherhood, it is still identified that gender stereotypes, gender-based discrimination and patriarchal male ideologies were inherent in the ways of their guiding children. In short, such trend of friend-daddies did not imply an revolutional change from male-centered patriarchal family structures to male-female cooperated family structures.

Manga develops by reflecting a change of society, reader's needs, and their thoughts and changes of tastes, sensitively. Shojo manga and Jyosei manga also do. We can find several kinds of meaningful changes in Japanese Jyosei manga in the 2010s. The works which represent preciousness of daily life, women's narrative and self-realization are gradually increasing. In addition, the works that deal with very touchy issues such as sex discrimination at work, sexual harassment begin to emerge. It has never been found in the manga of the former era. While this paper analyzes the social and cultural causes of these changes of the works that exclude romance and treat gender issues focusing on recent works, it examines changes of Japanese Jyosei manga in the 2010s and their meanings. I investigate the current trends of Japanese Jyosei manga in the 2010s through Umimachi Diary that represents a precious everyday life with woman-centered narrative, Metamorphose no engawa that deals with women's story from a new perspective, Good-bye My Miniskirt that tackles gender issues. Furthermore I intensively analyze how Nagi's Long Vacation and Darucyan, which win popularity from women in their 20s~30, represent lives and troubles of contemporary Japanese women. Nagi's Long Vacation represents the heroine's quest for a self throwing everything out. While Darucyan deals with self-realization, it forms of a bond of sympathy of readers by representing the heroine who suffers sexual harassment and inequal conditions very realistically. Nagi's Long Vacation and Darucyan have something in common with portraying troubles and self-realization of the working women in their 20s based on a indigenous reality to Japanese society very realistically. However they are unusual in that it is different from the manga of the former era in dealing with heroine's troubles and their solutions. The most distinctive changes of Jyosei manga since 2010 are that real issues surfaced with social changes. In addition, these social contradictions result from irrational discriminations and old customs of Japanese society for a long time. Manga reflects subtly the portraits of the times, their images of women, and their values. These changes of Jyosei manga also show the concerns of readers at that time, and it means that women began to be aware of the issues.
