Understanding of the maternal transcriptome increased to elucidate the underlying molecular mechanism of normal oocyte maturation, which depends on a precise sequence of changes in maternal genes expression. Previous reports that the translational potential of a maternal mRNA is generally determined by the length of the poly(A) tail, and deadenylation is usually the first sign of mRNA degradation. However, in vitro cultured system has the underlying molecular mechanisms remain unclear. We determined whether the role of molecular basis, four important maternal genes, C-mos, cyclin-B1 (regulatory subunit of MPF), BMP15 and GDF9, were selected for detection of their precise mRNA expression patterns by real-time PCR and for determination of their polyadenylation status by poly(A) tail PCR during oocyte maturation. In the present study. the abnormal expression of maternal mRNAs prior to zygotic genome activation, which results in suppression of the corresponding protein level, may be responsible for, at least in part, a profound defect in further embryonic development. Reasonable expression of maternal gene is crucial for proper oocyte maturation and further embryonic development.

21세기는 여성의 세기가 되어 원시적 모계 사회에서 진화된 현대화된 모계 사회로 변화될 것이다. 수많은 여성 발명가들이 우리사회의 난제를 풀어내고 화폐의 초상 인물로 부상되는 날을 그려본다.

Place names represent a lot of information about the region and the life of the local residents. In particular, old geographical names have more spatial informations than recent place names. This paper tried to analyze the distribution and characteristic of 'Dumo' which is one of the ancient place names and was studied by Nam youngwoo in 1996 for the first time. After considering the etymology and phonological structure of 'Dumo', the name 'Dumo' included the geographic conditions related to a mountain and river in itself. The total number of place names in the line of 'Dumo' which were collected by the author were 417 and they were distributed evenly on the Korean Peninsula. 85% of them were used for the human place names and 73% of the human place names were served as settlement names standing for a village or an administrative district. Thus the author analyzed the location and diffusion of 220 of settlement names in depth. As a result, villages named in the line of 'Dumo' preferred southern or eastern exposure and located in front of a mountain and around a river. After a village name 'Dumo' was set up, it produces other similar names in the line of 'Dumo' near the village so most place names of 'Dumo' were found with several names of 'Dumo' not alone.

This research studies the characteristics of the family systems of traditional societies in Black Africa. For this purpose, this study has chosen three subtopics: the distinctive features of traditional societies, marriage customs (polygamy and polyandry), and the societal features of patriarchal and matriarchal societies. First, we analyze men's and women's roles, ownership and management of the land, dowry, and social values of livestock as the distinctive features that support the family system in traditional Black African societies. These elements play an important role in increasing the number of family members. Next we analyze marriage customs-polygamy and polyandry-which increase the number of family members, on the one hand, and secure the labor force, on the other hand. Most traditional societies in Black Africa prectice polygamy. However, the $Bashil{\acute{e}}l{\acute{e}}$ and Bahima prectice polyandry. Polygamy in traditional societies in Black Africa is based on the traditional social customs that display the authority and dignity of the family head, who has control over all family members in both patrilineal and matrilineal societies. The authority and dignity of the family head are used to keep and increase the number of family members, that is, to secure the community firmly. Finally, most traditional societies are patrilineal. However, matrilineal societies are prevalent in the so-called Matrilineal Belt, which term refers to the savanna regions where Bantu peoples reside, that is, the coastal regions from the Angolan coast, bordering the Atlantic, to the Tanzanian and Mozambique coasts that border the Indian Ocean. These societies trace descent through the maternal bloodline. The traditional family system in Black Africa is based on economic social, and political factors, as well as on the community spirit of the members, which has resulted from the choices made to increase the prosperity and well-being of the people.

This study aims to explore emotional closeness between grandparents and grandchildren in Korean families with a focus on the lineage. The effects of the geographical proximity and the normative aspect as well as intergenerational financial, instrumental, and emotional supports were taken into consideration to accounting for the grandparent-grandchildren affective solidarity. Research questions are addressed using the data of "Survey on Generational Solidarity and Differences in Cultural Experience and Perception in Korea", and a series of multinomial regression model were conducted. Findings indicate that the salient factor to boost grandchildren's affective solidarity with paternal grandparents is financial transfers between grandparents and parents. By contrast, all types of intergenerational supports affected grandchildren's emotional closeness toward maternal grandparents. Geographical proximity was associated with the affective solidarity between grandchildren and maternal grandparents. The effects of normative solidarity were not shown at both lineages.
