Software product line development is a development paradigm that efficiently develops a product family by avoiding redundant development based on separation of the common part and the variable part of the product family. In software product line development, the source code that is used to produce a product family is called a product line code base, and when the product line code base is changed and the products of the product family are affected by the change, the activity of testing the affected products is called a product line regression testing. For product line regression testing, instead of conducting regression testing individually on each product of the product family, a more efficient regression testing would be possible if unnecessary testing that are irrelevant to the change can be avoided. This paper introduces SRTS, which is an automated method to efficiently perform software product line regression testing. SRTS divides the product line code base and test cases based on commonality and variability. Then SRTS identifies and selects the test cases affected by the change. Finally, it reduces unnecessary testing by rerunning only the selected test cases.

The results was as follows. First, education expenditures for on-line education are 64,900won and the English and the Mathematics as main reasons using on-line education were that it is available for 24 hours and cheaper than off-line education. The parents got information for on-line education by internet, mass media and their next-door neighbors.

The purpose of this study was to investigate the changes of family relations following the Internet use of housewives. The survey was performed on-line and off-line. 582 housewives who used the Internet at home gave valid responses to the questionnaire. The findings of tills study were as follows. First, after having started using the Internet, housewives felt that intimacy among family members has increased while the level of equality between couples unchanged. Second, the change in intimacy among family members has significant differences according to family adaptability and family cohesion. Whether or not other family members used the Internet also affected the intimacy among family members. Third, the change in equality between couples depended on their ability to use the Internet. This suggested that the ability to use the Internet was the core element to an equality. The results of this research suggested several implications for the public policy.

This study intends to provide foundational data for enhancing the welfare of customers purchasing digital products through analyzing the notes from written on-line reviews. The data used for the analysis are 6,342 on-line reviews for cell phones and digital cameras released from November, 2007 until April, 2008, which was posted on Naver Knowledge Shopping from November, 2007 until June, 2008. Through the on-line reviews, this article analyzed the evaluations on the digital products' hardware, software, design, service, price, and other criteria and the customers' emotional experience in the process of purchase, use, and possession. According to the results of the analysis, negative evaluation and emotional experience were originated from the company's information provision methods and purchase process. In addition, insufficient information searches in the process of online purchases, consumers' low right consciousness, and impolite on-line reviews were also problematic. Customers' evaluations and emotional experiences on digital products were conducted in a complex way. Based on that, this research makes suggestions in the company's marketing, customer education, and theoretical aspect.

It is widely agreed that customers' purchase are strongly influenced by their emotions. despite the obvious importance of eliciting positive emotional responses from customers, we find no record that family restaurants have ever measured or used customers' emotions as a management tool. This study aimed to verify the importance of the customers' emotion in the relational performance of family restaurant business. In order to achieve the object of the study, the effect of emotional factors on service satisfaction, revisit, word-of-mouth were analysed. The data were collected from 450 customers who had visited five family restaurants in Seoul more than once during the last three months from September 20 to October 5, 2002. Emotional variables in service experience process were grouped as three factors; in the middle of having food, in entering and leaving restaurant and in the waiting line. It is proved that customers had different emotions in each process of family restaurant service experience. Multiple regression analysis was employed to explore the influence of three emotional factors on relational performances such as satisfaction, revisit and word-of-mouth. It was found that customers were influenced by emotional factors in entering and leaving restaurant, secondly influenced in the waiting line and least influenced in the middle of having food. Finally, the findings indicated that customers' emotional factors in whole service experience process from entering to leaving the restaurant should be successfully cared by service staff. Future research is recommended to find out which specific emotional factors affected on relational performance of family restaurant.

In a software product line approach, developers first develop common software architecture and components by analyzing the characteristics of all software members, and then produce each application by integrating components. The approach is considered very effective means for developing and maintaining in parallel a software product family. Main disadvantage of this approach is that it requires a big up-front investment in preparing product line. Therefore, it takes time to deliver the first version. In this paper, we present an incremental method to develop software families, which requires small additional cost for initial versions and allows an organization to move smoothly to full-scale product line. We present our method by explaining how to record and upgrade the results of variations analysis, and show the application of our method by developing a family of YBS. Our method is a low-risk approach that can be effectively applied to an organization that starts developing software systems but has to deliver the first versions quickly to the market.

Natural increase rate in population is reached to 1.7% in 1975 fron 2.5% in 1966 because of the effect of Govermental Family Planning Program. The average number of present children and ideal children is just the same, 2.4 people, in this investigation. So, I assume that the number of present and ideal children is approaching each other. The rate of unmarried female workers who don't know even one thing about the know ledge of contraception was 23.9%, and especially that of rural women was 31.5% and 41.3% of them has never experienced contraception. 'Boy-preference' presented 60.1% of unmarried female workers and 79.1% of married women. 'Connection of a family line' related to 'Transfer to next generation of a family line' presented 38.0% and 'Trustworthiness' related to 'Leadership of a family' presented 26.0% (total 64.0%). As this point, Ive can find that this rate reveals the traditional sense of patriarchal system in society and family. The rate of women of experienced artificial abortion has been 52.1% and that of women using it as birth control caused by 'Many children' and 'Short brith-interval' 46.6% of women of experienced pregnancy. So, we can see that artificial abortion is a main cause of Maternal Health destruction.
