Co-residence is a type of intergenerational private transfers of resources: money, time and space. Adult daughters and their elderly parents decide to co-reside, depending on their utility levels before and after co-residence that mainly depend on the health status of the elderly. Therefore, co-residence implies positive net benefits to both parties in the sense that, when they co-reside, elderly parents share childcare and adult daughter provide elderly care. In other words, formal (paid) care can be substituted with informal (unpaid) one. Both marriage and giving births are considered as the major obstacles to labor market attachment of women who bear burdens of home production and childcare. Co-residence can be a solution for married women to avoid career interruption by sharing burdens with their elderly parents. However, most previous studies using the U.S. data on intergenerational private transfers focused on elderly care and have concluded that they reduce government expenditures associated with public subsidies to the elderly. This study focuses on adult daughters and it examines effects of co-residence on labor supply of married women in Korea, who face limited formal childcare programs in terms of both quantity and quality. It applies the Tobit model of married women's labor supply to the data from the Second Wave of the Korean Labor and Income Panel Survey( 1999), in order to investigate effects of co-residence and the work and health status of the co-residing elderly as well as their own health status. Four specifications of the empirical model are tested that each includes co-residence with elderly parents, their gender, or their work and health status. Estimation results show that co-residence, co-residence with female elderly, and co-residence with not-working female elderly have significant positive effects on labor supply of married women while poor health status of co-residing female elderly does not bring about any negative effects. However, co-residence with male elderly, regardless of their work and health status, has no significant effect The results indicate that co-residence is closely related to sharing of home production among female elderly and adult daughters who are married and, through intergenerational private transfers of resources in terms of time, it helps women avoid career interruption.

Focusing on the factors related to the amount of contact between young married women and their noncoresident parents and their noncoresident parents-in-law, the study hypothesized two scenarios. (1) filial piety scenario which predicts that the contact with one set of parents is not affected by accessibility of other set of parents, and (2) competition scenario which predicts that ease of contact with one set of parents inhibits contact with other set of parents. These scenarios were tested against the data from National Fertility and Family Health Survey in 1994. The regression analysis of intergenerational visits appeared to support the competition scenario : The parents-in-law and the parents seem to bs in competition for visits by young married women - distance from the parents from one side has a parallel relationship to more frequent visits with the other set of parents. This is a much more equal footing for both sides of the family than attention to filial piety would predict. although the level of support from the young generation may keep declining.

디지털 경제시대에는 시장의 힘이 고객으로 급속하게 이동하고 있다. 이러한 디지털 경제 시대의 지배 논리가 비즈니스 모델의 핵심인 분야가 전자상거래 분야이며, 기업은 성공을 위해서 고객관계관리를 통한 고객의 로열티 확보에 주력하여야 한다. 기존의 연구는 주로 단일 사업자가 모든 서비스를 제공하는 포탈 사이트형 비즈니스 모델에 초점이 맞추어져 왔다. 그러나 포탈형에서 허브형 비즈니스 모델로 바뀌고 있는 현재의 e-business 추세를 반영한 연구는 아직 이루어지고 있지 않다. 본 연구에서는 단일 사업자를 위한 것이 아닌 허브 사이트형과 같은 차세대 비즈니스 모델에서 사업자들간에 유기적인 정보의 공유와 제공을 통한 고객관계관리에 대해서 살펴보고, 이를 뒷받침하는 정보시스템을 개발하였다. 시스템의 개발과정에서는 다음과 같은 접근방법을 취하였다. 첫째, 고객정보를 공유해 활용할 수 있는 기반을 마련하기 위해 통합 고객데이터베이스를 구축하였다. 둘째, 통합 고객데이터베이스에 분석방법을 적용해 기본적인 고객분류를 하였다. 셋째, 통합 고객데이터베이스가 각 회원사의 백 오피스 시스템 즉 MIS와 통합되고, 통합된 고객정보와 기본적인 고객성향 분석을 토대로 각 회원사마다 독특한 방식으로 고객에 대한 전략적 세분화를 하도록 하였다.

The purpose of this research is to discover the value of experiencing the humanistic spirit of sharing, consideration, sympathy, and communication through the mentoring program between different generations through the . The provides collective mentoring to menti to involuntarily participating mentees, prioritizing traits such as truthfulness, flexibility, and consideration for others. The sharing within the is the sharing of human traits, and displays the characteristics of volunteering. For better mutual connection and interdependence between the mentor and mentee, concentration, sympathy, understanding, and assurance is also needed. Also, sympathy is key trait that both mentors and mentees should possess, along with communication, the lacking of which causes the contradictions within our society and amplification of generational conflicts. Thus, the show the potential to become a unique mentoring program that uses culture and art to experience the humanistic spirit. Also, this program is valuable in that it provides the opportunity for the matured generation to contribute to the local community.

The definition of mobile phone was a device that can make and receive telephone calls or messages for communication but it has rapidly developed from communication tool into multi-function device. Especially since release of smart phone, Korea is one of the highest country in the world and the statistics can be interpreted into people positively accept new technology. Therefore it's time to study on usage behavior according to different generation of mobile phone. Based on media richness theory and elaboration likelihood model, we analyzed factors affecting usage behavior of mobile phone. Case study methodology were constructed a survey to female university students from 20-24 years of age.

Studies were conducted to investigate hosts, life cycle, population dynamics and natural enemies of mulberry scale, Pseudaulacaspis pentagona Ta. & Tozz., from 1987 to 1988 in southern region of Korea. The host plants were 22 families and 74 species. Host plants belonged to genus Prunus in general were severely damaged due to mulberry scale. Mulberry scale was most likely to have three generations a year with first occurrence of larval stage from mid-May to late June, second occurrence from mid-July to mid-August and third occurrence from early September to late October including 3 peaks in early and mid-June, late July and mid-September. In case of each stage occurrence, eggs were peaked on 10th day, larvae on 25th day and adults on 7th day from beginning of occurrence, respectively. Natural enemies were observed as parasitoids of 3 species such as Aphytis diaspidis, Archenomus orientalis and Apterencyrtus mocrophagus and as predators of 3 species such as Chilocorus Kuwanae, Chilocorus rubidus and Hormonia axyridis. Shoot growth was affected by mulberry scale and Lepra to dwindle as much as half of normal growth.

The experiment was conducted to obtain estimates of heterosis, selective index, genetic advance and selective efficiency in cross among silkworm varieties. Seven parents, 21 F$_1$ hybrids, and 21 F$_2$ populaltions from diallel crosses among them were evaluated. The results obtained are summarized as follows: In male and female of F$_1$ generation, the negative heterosis was shown in two characters of fifth instar period and boiling on ratio, and the positive heterosis with the value of 20.90-37.60% in the other characters. In those of F$_2$, the nagative heterosis was shown in two characters of cocoon layer ratio and boiling off ratio, and the positive heterosis in the other characters. The selection weight of cocoon weight for bave weight was the highest of those of all the characters, and that of the combination of the fifth instar period and cocoon weight for it was the highest of those of all the combination. The genetic advance of cocoon weight toward bave weight was the highest of all the characters. The highest genetic advance and selective efficiency were shown in the combination of all the characters.
