Mother's view and mediating behavior of paternal grandparents-grandchildren is explored by using data of 159 mothers who have children at teens. The analysis indicates as below. 1. Mothers highly except the roles of grandparents such as teaching values and family historians, role models for good life, influencing on the developing of self-identity of grandchildren. However mothers want grandparents keep distance from the lives of grandchildren. This may be double message to grandparents that they may find it uneasy to accomodate. 2. Grandchildren's role is expected very positively by mothers. 3. Mothers' mediating level of paternal grandparents-grandchildren relations is neutral and a little bit positive on the whole. Mothers' mediating behavior between grandfathers-grandchildren is associated with mothers' view on the importance of grandfathers in the lives of grandchildren and residence pattern. Mothers' mediating behavior between grandmothers-grandchildren is associated with mothers' view on the importance of grandmothers in the lives of grandchildren, grandchildren's role, the intimacy between mothers and grandmothers and residence pattern.

This study examines pre-college study abroad (PSA, Chogi yuhak), which is one of the fastest growing phenomena among the various efforts for Koreans to learn English. The discussion includes the reasons why PSA has become so popular in the last decade under the name of globalization, the problems it has caused, and its new impact that this phenomenon has on Korean mothers. This study argues that PSA boom provides Korean mothers with an opportunity to pursue their own self-realization by studying abroad with their school aged children. These "new wild geese" mothers, who make double investments in their own education as well as in their children's in the U.S. represent important aspects of the contemporary Korean society regarding education, gender and neoliberal social atmosphere.

Continuously renewing the proteome, translation is exquisitely controlled by a number of dedicated factors that interact with the ribosome. The RNA helicase DDX3 belonging to the DEAD box family has emerged as one of the critical regulators of translation, the failure of which is frequently observed in a wide range of proliferative, degenerative, and infectious diseases in humans. DDX3 unwinds double-stranded RNA molecules with coupled ATP hydrolysis and thereby remodels complex RNA structures present in various protein-coding and noncoding RNAs. By interacting with specific features on messenger RNAs (mRNAs) and 18S ribosomal RNA (rRNA), DDX3 facilitates translation, while repressing it under certain conditions. We review recent findings underlying these properties of DDX3 in diverse modes of translation, such as cap-dependent and cap-independent translation initiation, usage of upstream open reading frames, and stress-induced ribonucleoprotein granule formation. We further discuss how disease-associated DDX3 variants alter the translation landscape in the cell.

Architectural researches on the traditional houses of Korea have been studied mainly based on the data collected in the field survey. From explosively incresed real mesurements and drawings in the field, plenty of data have been collected. Those have been the basic data for verifing and developing the theories on the traditional house. But after Korean war the researchers in South-Korea were not able to approach to the field in North Korea, so the new data of North Korea were not added any more. The poverty of real data have caused regional unbalance in the researches. This paper aims at collecting new data of traditional house in North Korea. But still being prohibited for the researchers of South Korea to approach to the field, I had to depend on the memories and experiences of the immigrants from North Korea who are now living in Kyon-Nam and Pusan Province. Through the questionnaire and drawings, they described vivid memory of their old houses. I was able to collect the data of 71 cases, which are significant and valuable as much as those of the real field are. The data include the address and site condition, family structure, economic condition, construction period of each house, The drawings by themselves show the building forms and plans, the plans of each building, and the included spaces. Although the quantity of those data is not enough for statistical analysis, it shows general tendency for analizing regional charateristics, the differnces among economical classes, and the periodical change. It opens the way for verfying the existing theory. Analizing the data, I have some conclusions as followings: a. Most of researchers have classified the dominant housing type of Hamkyong-Do as 'the double fold' type. In this study, all cases of Hamkyongbuk-do also show 'the double fold plan with Chongju-kan'. But in Hamkyongnam-do some cases show 'the double fold plan without Chongju-kan, or projecting the stable into the yard, which seem to be different type from 'the double fold plan with Chongju-kan' b. Existing theories classified the dominant housing type of Pyongahn-do as 'two buildings with pararell arrangement'. This classification is verified with the plentiful cases in this study. Futhermore, I found new tendency, that is, getting higher econnomic condition, they construct annex buildings between the main buildings. Finally their houses show 'scattered ㅁ shape'. The houses included in this two types has narrow and closed inner yard, which is different from the houses of the same shape in the south region of Korea. c. Existing theories classified the dominant housing type of Hwanghae-do as 'ㅁ sape with Daechong' type. I found many cases of 'ㅁ shape', but only two cases show 'Daechong'. 'The doble fold' type was also founded. Unfortunately very few cases were sent from Hwanghae-do, it is not enough for finding general tendency.

The purpose of this study was to examine the comparison of growth development, bone mineral density and nutrient intakes between double income families' preschool children(DIFPC) and full-time housewives' preschool children(FHPC). Subjects were 111 preschool children. Anthropometric characteristics and bone mineral density in right forearm were measured. The questionnaire was composed of health status, life style, dietary behaviors, and dietary intakes and was completed by the children's mothers. The average age of the DIFPC(n=60) was 53.02 months and that of the FHPC(n=51) was 54.80 months. The birth height and weight of the subjects were 50.47㎝ and 3.27㎏ for DIFPC and 50.85㎝ and 3.36㎏ for FHPC, respectively. The average height, weight, % body fat, and obesity index were 108.50㎝, 18.35㎏, 15.35%, 96.71% in DIFPC and 111.46㎝, 19.64㎏, 16.80%, 97.31% in FHPC, respectively. The bone mineral density in forearm of two groups were 0.24g/㎠ in all. The infant feeding method was significantly different between DIFPC and FHPC; 58.9% of DIFPC was fed formula, while 44.4% of FHPC was fed breast milk(p<0.05). Proportions of children for their regular meal were 59.4%, 89.6%, and 61.0% for breakfast, lunch, and dinner, respectively. The major reasons for irregular meal were lack of time and poor appetite for breakfast and snacks for lunch and dinner. Most of the children answered they have snack over once a day, and 60.0% have unbalanced diet. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B1, niacin, and vitamin C did not meet the Korean RDAs. The intakes of K and vitamin A for DIFPC were significantly higher than those of FHPC(p<0.05, p<0.05). In conclusion, double income families' preschool children more have a low frequency of breast feeding and low intakes of micro nutrients, such as K and vitamin A than full-time housewives' ones.

Tbr2는 T-box family 전사인자의 하나로써 뇌의 발달, 전구세포의 증식, 그리고 CD8+ T 세포와 자연살상세포의 분화와 기능에 중요한 역할을 하는 것으로 알려져 있다. 본 연구는 마우스에서 pilocarpine을 이용하여 경련중첩증을 유도한 후 나타나는 병리기전에 Tbr2의 연관성을 확인하였다. 경련중첩증은 해마의 CA3, hilus 그리고 조롱박피질 등에서 뚜렷한 신경세포의 손상을 유발하였다. 흥미롭게도 Tbr2를 이용한 조직 염색에서 경련중첩증 2일 후에 CA3와 조롱박피질에서 면역반응성이 뚜렷하게 증가하는 것을 관찰하였다. 또한 CA3와 조롱박피질에서 Tbr2를 발현하는 세포는 미세아교세포와 단핵구, CD8+ T세포 또는 자연살상세포 등 백혈구의 표지물질인 CD11b 와 이중염색되는 것을 발견하였다. Tbr2와 CD11b에 동시에 염색된 세포는 아메바 모양의 형태를 갖추고 있는 것을 발견하였다. 게다가 혈관 내피세포에서 발혈되는 platelet endothelial cell adhesion molecule-1(PECAM-1)과 이중 염색한 결과 Tbr2를 발현하는 세포가 CA3 지역의 혈관내에 다량 존재하는 것을 확인하였다. 이상의 결과를 종합할 때 Tbr2를 발현하는 세포는 뇌 조직으로 이주하는 백혈구일 가능성이 높음을 보여준다. 이러한 결과는 경련중첩증에 따른 신경병리기전에 Tbr2가 관여할 가능성이 높음을 처음으로 제시하였다.

The DNA sequence of the chitosanase gene (choK) from $\beta$-Proteobacterium KNU3 showed an 1,158-bp open reading frame that encodes a protein of 386 amino acids with a novel 74 signal peptide. The degenerated primers based on the partial deduced amino acid sequences from MALDI- TOF MS analyses yielded the 820 bp of the PCR product. Based on this information, double inverse PCR cloning experiments, which use the two specific sets of PCR primers rather than single set primers, identified the unknown 1.2 kb of the choK gene. Subsequently, a 1.8 kb of full choK gene was cloned from another PCR cloning experiment and it was then subcloned into pGEM T-easy and pUC18 vectors. The recombinant E. coli clone harboring recombinant pUC18 vector produced a clear halo around the colony in the glycol chitosan plates. The recombinant ChoK protein was secreted into medium in a mature form while the intracellular ChoK was produced without signal peptide cleavage. The activity staining of PAGE showed that the recombinant ChoK protein was identical to the chitosanase of wild-type. The comparison of deduced amino acid sequences of choK revealed that there is 92% identity with that of Sphingobacterium multivorum chitosanase. Judging from the conserved module in other bacterial chitosanases, chitosanase of KNU3 strain (ChoK) belongs to the family 80 of glycoside hydrolases.
