이 연구는 시간압박의 개념을 중심으로 남녀에 따라 지각하는 시간압박수준이 어떻게 차이가 나고, 시간압박에 영향을 미치는 관련요인들에서의 성차가 무엇인지 살펴보고자 하였다. 자료는 2004년 생활시간자료를 활용하였다. 일하는 연령에 해당하는 25-54세의 기혼의 대상자들만을 선별하여 살펴본 분석결과, 첫째, 평균적으로 남성이 여성보다 시간압박을 더 많이 지각하는 것으로 나타났다. 취업여부와 성의 조합형태로 살펴본 교차분석 결과에서는 취업남녀가 유사한 시간압박 수준을 나타내는 가운데 비취업여성, 비취업남성 순으로 시간압박을 지각하는 것을 관찰할 수 있었다. 둘째, 시간압박을 종속으로 하는 순서화 로짓분석결과, 시간압박과 관련 있게 나타난 특성의 구성에서 남녀에 따른 차이점과 공통점이 함께 발견되었다. 남성의 경우 사회인구학적 특성과 직업특성과 관련된 특성 및 시간활용이 그들의 시간압박과 관련이 있는 것으로 나타났다. 여성의 경우에는 시간압박과의 관련요인들이 남성의 경우와 비교해 볼 때 더 다양하였다. 교육수준, 소득, 직종, 근무형태, 요일, 자녀연령을 비롯하여, 임금노동시간, 이동시간, 여가시간을 비롯하여, 돌봄노동시간, 가사노동시간 그리고 전화통화시간까지도 시간부족과 관련이 있는 것으로 나타났다.

2012년 구미 불화수소 누출사고 이후 화학 물질 사고에 대한 사회적 불안감이 증폭되었고, 이러한 불안감 해소를 위해 2015년부터 장외영향평가제도가 도입되었다. 장외영향평가제도는 대부분의 화학물질을 대상으로 하며, 반도체, 디스플레이, 태양광 산업 등 첨단산업 분야에서 주로 사용되는 대부분의 고압 독성가스가 이에 포함된다. 우리나라 기업들이 첨단산업 분야에서 높은 경쟁력을 보유한 만큼, 국내에서 고압 독성가스 사용량은 지속적으로 증가하고 있으며 이에 따라 사고발생 가능성도 높아질 것으로 예상된다. 이러한 상황에 따라 본 연구에서는 국내에서 사용되는 고압 독성가스 중 제조량 및 사용량이 높은 물질을 대상으로 미국 환경보호청과 미국 해양대기국이 공동 개발한 ALOHA 프로그램을 활용하여 사고영향범위를 평가하였으며, 알진의 사고영향범위가 4,700 m로 가장 넓은 것으로 나타났다. 사고영향범위 결과는 고압 독성가스 누출 시 효과적인 안전거리 결정에 활용할 수 있을 것으로 기대한다.

The purpose of this study was to explore the relationship between childrearing belief and parental efficacy of women before and after childbirth. For this purpose 253 pregnant women and 256 mothers with infants under one year of age were contacted and asked to fill in a packet of survey questionnaire at their visits to obstetrician, gynecologist and pediatrician. The questionnaire includes questions about what mothers value in childrearing, their expectations for their children and parental efficacy. Data collected were analyzed using SAS PC program. It was reported that comparing to mothers, pregnant women view childrearing in more ideal lights and expect their children to be more exceptional. Also working mothers reported comparatively lower parental efficacy than full-time mothers suggesting that social support system to minimize pressure coming from work for working mothers with young children should be provided and the parental education methods to enhance the parental efficacy should be sought.

Children have become the target of intense and specialized food advertising efforts. This study examines the content of TV food advertising and discussed possible concerns from the perspective of children. A total of 102 ads were collected from two cable networks aimed at children. Most of the food ads used emotional appeals and did not provide information clues such as nutrition values. Ads with high sales pressure and celebrity endorsements appeared frequently and the ads for snack foods and high-carbohydrate bakery products were dominant. Understanding food ads can be a significant indicator to establish the orientation of consumer ad education and build educational programs appropriate for children. The issue that appears conspicuous in child targeted advertising and marketing is the childhood obesity and food advertising relation; subsequently, there is a need to evolve advertising that targets children into a positive educational information source.

Traditional Internet pricing schemes are coming under continual pressure to adapt to, and encourage, a changing mix of Internet applications and consumer usage patterns. Much research effort over the last decade has been focused on developing more efficient and attractive charging schemes. However, none of the proposed models has been widely deployed. This raises questions regarding the inhibiting factors and missing pieces that make pricing the Internet such a challenge. In this paper, we discuss the problems with current Internet pricing schemes, review the history of Internet pricing research over the last ten years, and summarize the key features and motivations of the most significant models. We develop a novel visual approach to comparing and evaluating such schemes using a three-dimensional (3D) metric encompassing technical efficiency, economic efficiency, and social impact. We address and discuss the important factors that have inhibited the deployment of the reviewed models and suggest productive areas of focus for future Internet pricing research.

The vibration of slab causes a sudden change of air pressure in the interface between slab and air to create structure home sound. Floor impact noise induced from the vibration of slab became one of the hottest social issues in these day, and it took the biggest parts of the cause of damage in environmental dispute. Because the structure borne sound of slab is different from the dynamic characteristic of slab, it is required more precise vibroacaustic analysis. In this study, we was trying to understand by what mechanism the slab noise is induced from the slab vibration and the relationship between the dynamic propety of slab and the noise is shown by the numerical simulation.

Purpose: This study was done to review Taegyo types, the practice of Taegyo, factors of Taegyo, and the effect of Taegyo programs in Korea. Method: This study reviewed the preceding research related to Taegyo through websites, articles, and books. Result: As a result of a review of Taegyo types, the practice of Taegyo, factors of Taegyo, and the effect of Taegyo programs through websites, articles, and books, it was summarized that pregnant women were independent people able to practice Taegyo from pre-pregnancy to childbirth for baby's health. If she practiced encouraging behaviors of Taegyo with her husband's physical, emotional, and economical support, she and her husband would easily transition to parenthood and form strong attachments with their baby. In addition, the rate of mother's postpartum depression was decreased. However, some pregnant women felt a psychological, social, and economical pressure to practice Taegyo. Conclusion: Activating organized and accessible to support systems and community networks, such as community health centers, nurses can help pregnant couples to increase self-care through the performance of Taegyo.

Recently social demands of fuel economy and environmental regulation require the development of light materials and new manufacturing technologies. In this point, aluminum tube hydroforming, which is satisfied with good strength-to-weight ratio and recyclability, is new innovative concept. but, up to now the level of that is relatively low. In this paper, we studied formability of different aluminum tubes in different heat treatments under internal pressure and axial feeding, and mechanical properties of aluminum tubes before and after hydroforming.

In Internet age, traditional transaction concepts are being examined in new perspectives. Electronic commerce, as a new transaction paradigm, is being paid attention to reexamine traditional marketing theories. In this study, equity is adapted to electronic commerce. We add Navigational Equity to existing equity concept: Payment and Service (Huppertz et al 1978). The research model of this study consisted of three major constructs such as equity, normative comparison of equity and consumer satisfaction in electronic commerce. Additionally, the environments of Internet navigation, which include system quality, easy for use, social pressure, playful aspects, and security check, etc. were analyzed. The propositions were drawn from the research model of this study. These propositions will be used to generate hypotheses constructing simultaneous equation model. More empirical study of future is expected.

This study investigates how cognitive and affective conflict affect performance and social outcomes in the new product situation. We examine the corporate, project, and personal characteristics that determine the level of inter-functional conflict between marketing and R&D. From a survey of Korean high-tech companies, we found : (1) time pressure was positively related to cognitive and affective conflict, (2) joint reward systems, interdepartmental connectedness, and years of education were negatively associated to cognitive conflict, (3) while cognitive conflict was positively related to new product creativity and NPD performance, affective conflict was negatively associated to marketing-R&D integration and perceived effectiveness of the relationship, as well as new product creativity and NPD performance.
