The purpose of this study was to identify a couple's parental efficacy combination and, then, analyze parental role-sharing and parenting stress according to this combination type. The subjects were 307 couples who have a child in 1st or 2nd grade. The main results were as follows: First, fathers and mothers, as a group, did not differ in terms of parental efficacy. Secondly, some demographic variables related to parental efficacy. Thirdly, there are more couples who have similar levels of parental efficacy than those who have different levels of parental efficacy. Fourth, no significant difference in parental role-sharing was found among the 4 types of couple's parental efficacy. Fifth, mothers had low parental stress when both of the couple had high levels of parental efficacy while fathers perceived low parental stress if only he, himself, had a high level of parental efficacy.

Gremlin-1 (GREM1) has been defined as an antagonist of bone morphogenetic proteins (BMPs), particularly during embryonic development and tissue differentiation. However, recent studies have shown that GREM1 has BMPs-dependent or -independent functions in diverse human diseases. GREM1 plays a key role in the process of organ fibrosis, including lungs, kidneys, and so on. The GREM1-induced fibrosis typically promotes the development of other diseases, such as pulmonary hypertension, renal inflammation, and diabetic nephropathy. More recently, considerable evidence has been reported showing that GREM1 is involved in the promotion and/or progression of tumors in vitro and in vivo. It also performs an oncogenic role in the maintenance of cancer stem cells. Although GREM1 is known to function in a variety of diseases, here we focus on the role of GREM1 in cancer, and suggest GREM1 as a potential therapeutic target in certain types of cancer.

Cancer is the leading cause of mortality worldwide. In cancer progression, sex hormones and their receptors are thought to be major factors. Many studies have reported the effects of estrogen and estrogen receptors (ERs) in cancer development and progression. Among them, G protein-coupled estrogen receptor (GPER), a G protein-coupled receptor, has been identified as an estrogen membrane receptor unrelated to nuclear ER. The mechanism of GPER, including its biological action, function, and role, has been studied in various cancer types. In this review, we discuss the relation between GPER and estrogen or estrogen agonists/antagonists and cancer progression.

본 연구는 연구논문의 논리적 의미 구조 메타데이터 항목에 해당하는 데이터에 담겨 있는 문장의 구성에 따라 시스템에서 적절한 항목으로 자동 식별 처리될 수 있도록 하는, 문장의미론(Sentence Semantics)적 분석 방법을 제안하고자 하는 목적으로 수행되었으며, 의미 구조 메타데이터 항목 중 'Research Objectives'와 'Research Outcomes'에 해당하는 연구 논문 문장의 구조를 어절 수, 접속어 종류, 다수 출현한 단어들의 문장 내 역할, 문장에서 다수 출현한 어미 형태 등을 기준으로 분석해 정리하였다. 연구 결과, 문장들의 어절 수는 'Research Objectives'는 평균 38개, 'Research Outcomes'는 평균 212개로 나타났으며, 접속어의 경우 'Research Objectives'는 인과-순접-대등-환언/요약 관계를 나타내는 접속어 순으로, 'Research Outcomes'는 인과-대등-순접-환언/요약 관계를 나타내는 접속어 순으로 많이 출현한 것으로 파악되었다. 출현빈도가 높은 분석 대상 단어들은 각각 문장 내에서 주어, 목적어, 서술어 역할 등으로 사용되고 있었으며, '역할'이나 '요인', '관계'는 목적이나 결과 부분 모두에서 비슷한 역할을 담당하고 있었지만 '연구'는 같은 단어라도 연구의 목적 부분과 결과 부분에서 사용되는 역할에 차이를 보였다. 마지막으로 문장 내 동사의 어미는 'Research Objectives'에서 '~고자'와 '~였다', 'Research Outcomes'에서 '~었다', '~있다', '~였다'가 많이 출현하였다. 본 연구는 연구자의 학술적 이해형성을 지원하기 위해 연구논문이 담고 있는 공통된 논리적 의미를 반영한 메타데이터 요소의 자동 식별과 입력 방안을 제시하는 데 활용할 수 있는 기초 연구로서 의의가 있다.

Apparel companies define their target customers to integrate consumers' needs into their product development processes. The sizing standards play a significant role in ready-to-wear garment business. Consumers' body build and sizes are different according to gender, age, and body type. The consumers' morphological feature of the one geographical area has changed with immigration, aging, and lifestyle change. In this study the way of defining body types in the standard garment sizing systems published in USA., UK, Germany, Japan, and Korea were compared. The results of this study show that most of the systems classified the body types by the index value. The chest-waist drop value was used for men's body type classification. Women's body types were defined by hip proportion. The hip-bust drop value was used for it. German and European garment sizing systems provide a wide range of men's body types. US men's garment sizes are developed for very conservative body type. US women's garment sizing system has had clearly defined women's body types. The Misses body types projected in the US garment sizing system had changed as women's waist girth got bigger compared to the past. In 2011 the US Misses sizes were divided into Curvy Misses size and Straight Misses size by the hip-waist drop value. The Curvy Misses sizes have smaller waist girth and larger hip girth than the Straight Misses sizes.

The nonlinearity of a cable-stayed bridge results in the large displacement of main girder due to a long span, the large axial forces reduce the catenary action of cables and the flexural stiffness. Therefore, the static and dynamic behavior of pylon for a cable-stayed bridge plays an important role in determining its safety. This study was performed to find the behavior of pylon of cable-stayed bridge for the first-order analysis considering of axial load only and for the second-order analysis considering of lateral deflection due to axial load. The axial force and moment values of pylon were different from the results of the first-order analysis and second-order analysis according to pylon shape and cross beam stiffness when the pylon was subjected to earthquake and wind loads. In the second-order analysis, comparing the numerical values of the member forces for the dynamic analysis, types 3 and 4 (A type) were relatively more advantageons types than types 1 and 2 (H type). Considering the stability for pylon of cable-stayed bridge (whole structural system), types 3 and 4 (A type) with pre-buckling of girder were proper types than types 1 and 2 (H type) with buckling of pylon.

The purpose of this study was to explore the typology of child care, investigate the characteristics of child care types, and analyze the differences in time deficit as well as time satisfaction by the types of child care for dual-earner couples with preschool children. The data source for this research was the 2009 Time Use Survey conducted by the Korea National Statistical Office. Dual-earners aged 20 to 59 years completed 1,568 time diaries, which were analyzed using chi-square, cluster analysis, and ANOVA analysis. Child care time was classified into three types in the three categories of child care, household work sharing and leisure sharing for both males and females respectively. Three types for husbands were named "vulnerable", "household work child care predominant" and "leisure predominant". The three types for wives were named "vulnerable", "household work child care oriented" and "household work child care". The characteristics of each type depended on age, education, weekly working hours, gender role of husbands and age, weekly working hours of wives. The vulnerable type of wives showed the highest level of time deficit. Based on the results, implications for Public policy on child care and various types of education as well as programs were suggested.

The primary purpose of this study was to develop an educational tool that can be used in teaching young children about different types of sex roles. The secondary purpose was to observe and analyze the effects of watching different sex role video programs on preschool children's sex role stereotypes and to determine the lasting effects. The subjects of this study were 89 six year-old kindergarten children, forty five were girls and forty-four boys. Each child was interviewed individually and tested at three different points in time: 1 week before the treatment, immediately after the treatment, and 4 weeks after the treatment. Three different statistical procedures were used in analyzing the data: ANOVAs for sex differences in sex role stereotypes. ANCOVAs for the different effects of traditional sex role programs and reversed sex-typed sex role programs, and ANCOVAs and Lindquist type III ANOVAs for the lasting effects of the treatment. The findings of the study indicated that (1) the children showed sex differences in the scores of sex role stereotypes of own, opposite sex and child activity; (2) there were differences in the scores of sex role stereotypes in terms of own and opposite sex. That is, viewing the reversed sex-typed programs caused a decrease in children's sex role stereotypes; and (3) the traditional and reversed sex-typed sex role programs tested four weeks after treatment showed significant lasting effects of sex role stereotypes in terms of opposite, composite and adult activity. In conclusion, the results of this study suggest that the sex stereotypes of kindergarten children can be changed through sex role VTR programs.
