The newly-found thiol peroxidases (TPx) with a conserved cysteine as the primary site of catalysis are capable of catalyzing the thiol-dependent reduction of peroxides. However, the cellular distributions of the isoforms remain poorly understood. As a first step in understanding the physiological functions of the TPx isoforms, we examined the cellular and tissue distribution of the isoenzymes in various bovine tissues. The tissue distributions of TPx isoenzymes indicate that two types of TPx are widely distributed throughout all of the tested tissues. These two forms are the predominant proteins, with levels of the proteins being quite different from each other. The level of predominant TPx proteins, named type II (TPx II) and type V (TPx V), appeared to be very different with respect to tissue type. The cellular distribution and level of TPx isoenzymes also varied with the types of cells. Immunoblot analysis of the mitochondrial and cytosol fractions from various tissues indicates that TPx III is a unique mitochondrial form. Based on the different tissue and cellular distribution of TPx isoenzymes, we discuss the physiological function of TPx isoenzymes, especially the ubiquitous TPx II.

This study was designed to investigate the nature and magnitude of disability among non-institutionalized elderly in urban area(Seoul city). From November 1987, through December 1987, 1,054 individuals aged over 65 years from the sampled of clustered random sampling method were interviewed in person. The physical disability findings support the well known relationship between physical disability and age. The magnitude of disability, however, is not as great as conventional wisdom might suggest. And this paper reports results on the prevalence of social disability : housekeeping transportation, food prepatation, grocery shopping, social interaction, intellectual activity, and social role. The magnitude of social disability increase with advancing age. Women, in general, report a higher degree of social disability than man. These findings are compared with other investigations of physical and social disability among the elderly.

Though the kitchens of traditional residence architecture are recognized as having significant importance to houses themselves, to women who are supposed to do most of the housekeeping work, they are generally thought to be irrational space. This study tries to show through a demonstrative way that the kitchen space of traditional houses is the sensible and rational living space for the health's sake of all family members in the relations among humans, space and environment. Through this study, we were able to see that the architectural work of our ancestors in designing space had different views from those of the West in that our ancestors had sought the outcome taking the interrelations among environment-humans-space seriously in order to shape the physical organization for human beings.

This analysis of the portrayal of characters in 74 picture books used in kindergarten focused on the gender types and roles of girls and boys, adult females, adult males, and feminist perspectives or sexism. Results showed that girls were rewarded according to their abilities and accomplishments, and they were considered to have equal rights; boys were depicted as dominant, positive, logical, courageous and having initiative; adult females, especially mothers at home, were responsible exclusively for housekeeping and child rearing; adult males, including fathers, were depicted as dominant characters in a variety of professional occupations and social activities, nonetheless, in many books, children were depicted as androgynous personalities having human rights. Though these results show changes in gender stereotypes from the 1970s and 1980s, subtle biases of gender still remain in children's books.

In the post genome project era, it is well established that the human genome contains a smaller number of genes than expected. The complexity found in higher organisms can be explained if proteins are multifunctional. Indeed, recent studies are continuing to reveal proteins that are capable of a broad repertoire of functions. A good paradigm for multifunctionality can be found in the amino-acyl tRNA synthetases (aaRSs), an ancient conserved family of proteins. This unique family, which is comprised of 20 different enzymes, is well known for its participation in protein synthesis. Several studies have described numerous examples of these "housekeeping" proteins taking part in extensive critical cellular activities. In this review, we focus on a member of that family, lysyl-tRNA synthetase (LysRS), which has been shown to have a dual functionality. In addition to its contribution to the translation process, LysRS also takes part in the regulation of MITF and USF2 target genes. This phenomenon was first described in mast cells.

The purpose of this study was to examine preschool children's participation tendency and use of play materials in imaginative play. The subjects for the study included 22 boys and girls in nursery school. These children were observed for 110-3-minutes of play behavior during free play at nursery school, especially in block area and housekeeping area. The results obtained from the study were as follows. 1. There was a significant association between paricipation tendency in imaginative play and age or sex, Boys engaged in more social imaginative play than girls, and four-year-olds engaged in more social imaginative play than three-year-olds. 2. There was sex difference in the content of imaginative play and use of play materials. That is, boys usually chose masculine kinds of toys such as block, cars, trucks, and manipulative materials. And the boys' common fantasies were about car, robert and fighting. Girls usually chose play dough, kitchen sets, and blocks and there were maines stories of family life and cooking. 3. Children preferred to use more realistic toys in imaginative plays and there were few cases of imaginative plays with no materials.

The objective of this study was to perform genetic diversity analysis of 13 strains isolated from South Korean foods by multilocus sequence typing (MLST). For typing, seven housekeeping loci (atpA, dnaA, dnaK, gyrB, pheS, pyrG, and rpoA) were selected, amplified and analyzed. Fifty-one polymorphic sites varying from 1 to 22 in each species were identified. Thirteen sequence types were generated with allele numbers ranged from 2 to 10. The overall relationship between strains was assessed by unweighted pair group method with arithmetic mean dendrogram and minimum spanning tree. In addition, combined spits tree analysis revealed intragenic recombination. No clear relationship was observed between the isolation sources and strains. The developed MLST scheme enhanced our knowledge of the population diversity of Leu. citreum strains and will be used further for the selection of industrially important strain.

Noting the changes within the Singapore construction industry, fuelled by the government's 'green' initiatives in tandem with the prolonged effect of the 1997-2005 recession, this paper investigates Singapore contractors' attitudes towards environmental sustainability. Data were collected from 34 interviews with senior management of large and medium-sized general building contractors and the firms' archival records. The results show that the majority of the contractors embrace positive attitudes towards environmental sustainability. The respective contractors explicitly express their environmental drives by incorporating keywords such as 'quality', 'sustainability' and 'environmental and social benefits' into their firms' mission statements. The results also show that three environmental-related measures implemented by all contractors are: (i) stricter housekeeping procedures in construction sites; (ii) stricter wastage rates for construction materials; and (iii) greater focus on Just-In-Time delivery to minimise materials deterioration due to inappropriate site storage.

산업화 이후 여성, 특히 기혼여성의 경제활동 참가율이 급격히 증가하고 있다. 따라서 본 연구에서는 기혼여성의 고용지위 결정 시에 고려되어야할 변수들에 대해서 분석할 필요가 있을 것으로 판단된다. 이에 기혼여성의 고용지위를 결정하는 변수들을 개인관련변수, 자녀관련 변수, 가구관련변수, 취업관련변수 등으로 구분하여 연구모형을 설정하였다. 이를 근거로 기혼여성의 고용지위를 결정하는 변수들에 대해서 다항로짓회귀분석을 실시하여 다음과 같은 결과를 도출하였다. 첫째, 개인특성변수에 대한 분석결과, 기혼여성은 도심에 거주할수록 그리고 학력이 높을수록 임금근로의 고용지위를 갖는 것으로 나타났다. 둘째, 자녀관련 변수에 대한 분석결과, 자녀의 수가 많으며, 6세 미만의 자녀가 존재하지 않을 경우 임금근로의 고용지위를 갖는 것으로 나타났다. 셋째, 가구관련특성 변수에 대한 분석결과, 가족이 핵가족일수록 그리고 가족 구성원 중 소득원 수가 적을수록 비임금근로의 형태를 갖는 것으로 나타났다. 마지막으로 취업관련 변수에 대한 분석결과에서는 여성이 혼전에 취업을 하였을 경우와 남편이 취업을 하지 않은 경우, 그리고 남편의 직종이 비전문직일 경우에 임금근로의 고용지위를 갖는 것으로 나타났다. 이상의 결과 분석을 통해 기혼여성의 고용지위 결정에 영향을 미치는 요인이 차이를 보임으로써 기혼여성의 고용지위 향상을 위해서는 다음과 같은 방안을 제시하고자 한다. 첫째, 기혼여성의 경우 어린 자녀가 있을 경우 고용지위가 낮게 나타나 기본적으로 결혼 및 출산으로 인한 가사 및 자녀양육 부담이 기혼여성의 지속적인 취업을 방해하는 요인으로 작용할 수 있어 이에 대한 문제해결 방안이 요구된다. 이를 위해서는 선진국의 경우에서와 같이 가사 및 자녀양육과 경제활동을 병행할 수 있는 탄력적인 근무시간제도 활성화가 필요하겠다. 그러나 이러한 탄력근무제도 활성화는 관련된 보호법 제정 등 제도적인 보호가 따라야만 실효를 거둘 수 있을 것이다. 둘째, 가사와 경제활동을 조화롭게 병행할 수 있는 제도로 가장 대표적으로 논의 되는 제도가 육아휴직제도이다. 현재 육아휴직제도가 법제화되어 있기는 하지만 그 활용도가 매우 저조한 실정이다.
