  • This research was attempted to investigate the sex bias in nutrition knowledge, food preference and food roles in the family. 152 couples living in Seoul, Cheonan in the 205∼605 were selected for this research as subjects from October 1 to December 20, 1991. The data analysis was made by way of ire quency, percentage, X2-test using SPSS package. The summarized results are as follows. 1. The survey on the sex bias in nutrition knowledge related heart disease on the subjects showed that there were no significant differences between men and women. But women had a relatively good nutrition knowledge than men. Especially women had a good nutrition knowledge that low sodium diet and exercise are efficient on preventing heart disease. 2. On the food preference, the subject showed significant difference between men and women. Men showed a relatively highest preference for protein food just as pork, fish, and tofu. Women showed a relatively highest preference for bread, fruit and vegetable. 3. On the food roles, the subjects showed that gender difference in household labor regarding food preparation still exit. Food-related activities are clearly still the domain of women in most families. Husbands and wives in younger families tended to think the husbands showed increase their efforts in food related activities.

  • Stress coping mechanisms are critical to minimize or overcome damage caused by ever changing environmental conditions. They are designed to promote cell survival. The unfolded protein response (UPR) pathway is mobilized in response to the accumulation of unfolded proteins, ultimately in order to regain endoplasmic reticulum (ER) homeostasis. Various elements of coping responses to ER stress including Perk, Ask1, Bip, Chop, Gadd34, Ire1, Atf4, Atf6, and Xbp1 have been identified and were found to be inducible in oocytes and preimplantation embryos, suggesting that, as a normal part of the cellular adaptive mechanism, these coping responses, including the UPR, play a pivotal role in the development of preimplantation embryos. As such, the UPR-associated molecules and pathways may become useful markers for the potential diagnosis of stress conditions for preimplantation embryos. After implantation, ER stress-induced coping responses become physiologically important for a normal decidual response, placentation, and early organogenesis. Attenuation of ER stress coping responses by tauroursodeoxycholate and salubrinal was effective for prevention of cell death of cultured embryos. Further elucidation of new and relevant ER stress coping responses in periimplantation embryos might contribute to a comprehensive understanding of the regulation of normal development of embryonic development and potentiation of embryonic development in vitro.

  • 제철공정의 더스트류로부터 제조된 비소성펠릿의 고로 조업의 가능성을 파악하기 위해서 다음과 같은 고온특성을 조사하였다. 고로용 CBP는 상온강도 외에 고온특성기준을 추가하여 검토한 결과, 다음과 같은 결과를 얻을 수 있었다. CBP의 염기도는 1.7 전후가 적절한 고온특성을 나타내었으며, 결합제로서 포틀랜드계 보다는 수재 슬래그계 시멘트가 우수한 용융특성에 적절함을 확인하였다. 또한 연화-용융사이의 압손누적량 기준으로 볼 때 염기도 2.6이상의 CBP는 노내에서 통기성 악화 가능성을 나타내었다. 따라서 결합제의 종류보다는 기본적으로 염기도 관리가 중요하며 결합제는 펠릿의 압축강도 및 양생시간등을 고려하여 선택할 필요가 있음을 확인할 수 있었다.

  • Effective thermal conductivities and pressure-drop-related properties of aluminum foam metals have been measured. The effects of porosity and cell size in the aluminum foam metal are investigated in detail. The porosity of the foam metal, considered in the present study, varies from 0.89 to 0.96 and the cell size from 0.65㎜ to 2.5㎜. The effective thermal conductivity is evaluated by comparing the temperature gradient of the foam metal with that of the thermal conductivity-known material. The pressure drop in the foam metal is measured by a highly precise electric manometer while air is flowing through the aluminum foam metal in the channel. The results obtained indicate that the effective thermal conductivities are found to be increased with a decrease in the porosity while the effective thermal conductivities ire little affected by the cell size at a fixed porosity. However, the pressure drop is strongly affected by the cell size as well as the porosity. It is seen that the pressure drop is increased as the cell size becomes smaller, as expected. The minimum pressure drop is obtained in the porosity 0.94 at a fixed cell size. A new correlation of the pressure drop is proposed based on the permeability and Ergun's coefficient for the aluminum foam metal.

  • This paper examines the validity of the newly developed IT consulting SERVQUAL measurement tool. In an attempt to measure Ire IS customers' expectations and perceived quality of the services they received, the researchers developed a diagnostic tool of SERVQUAL based on the solid theoretical background, which can specifically be applied to the IT consulting service sector. This on-going research so far, has been applied to six (6) different organizations that have received IT consulting services over the past years. From the preliminary data collected, the correlation and the factor analyses were conducted to understand the underlying concept and refinement of the measurement tool. Although the correlation analysis showed a little tendency of collinearity among some of the variables, all showed sound relationship of the proposed hypotheses. The exploratory factor analytic approach was chosen because it does not set any priori constraints on the estimation of components or the number of components to be extracted. The number of different factor solutions was extracted and tested to see which solution represents better grouping of the variables. The Crombach's Alpha was computed on different combinations of the factor solutions to ensure validity. The results show 8-dimensional IT consulting SERVQUAL measures which they are, assurance, knowledge & skill, customer relationship, support, empathy, process management, expertise, and education, seem more appropriate than the originally proposed 6 dimensions. The study approach was non-experimental cross-sectional research design. The longitudinal design of follow-up studies to periodically revise and refine current measure is strongly recommended for fine tuning of the tool.

  • AC PDP의 구동파형은 Reset 구간에서 명암비를 높이고 화질향상을 위해서 전압파형을 서서히 증가시키고 또 감소시키는데, 이 전압파형의 기울기와 크기가 온도와 더불어서 PDP의 화질과 관련이 있다. 그래서 본 논문에서는 Reset 구간에서 Y 전극에 인가하는 램프파형의 setup 및 setdown 구간에서의 기울기와 -Vy전압을 온도에 따라서 가변함으로써, 주위의 온도가 상온에서 저온이나 고온으로 변화하여도 PDP의 화질이 영향을 받지 않고 최상으로 유지하게 하는 온도 적응형 RESET 파형 발생회로를 제안하였다.

  • Heungdukwang's(興德王) costume ordinance(834A.D.) is a very important written historical record because it reveals Tongil Shilla's(統-新羅) costume. And among the clothing pieces that appeared in Heungdukwang's(興德王) costume ordinance, from Pyosang(表裳), Naesang(內裳), we know they wore one skirt over another. But skirts appearing in visual records are wort in waist line or breast line, and when they wore skirts in breast line, there were shoulder belts or not. Also among the clothing pieces that appeared in Heungdukwang'a (興德王) costume ordinance, Yo( ) and Ban( ) seems to be connected with skirt. but it is not clear. So this study focuses on the history of wearing skirt in breast line and one skirt over another, shoulder belts of skirt, and relation among yo( ), Ban( ) and skirt. The results are as follows. First, wearing skirt in breast line is already appeared in Ancient Shilla's(新羅) clay figure, and wearing one skirt over another is also appeared in Sunhung tomb's mural painting. so it is not completely under the influence of Tang(唐). Second, the shoulder belts of skirt is for convenience of action, But, at that time, there is no shoulder belts of skirt in Tang(唐). Third, between Yo( ) and Ban( ), If Yo( ) is connected with skirt, it is a shoulder belts of skirt or waist of skirt. And Ban( ) is a ire of skirt.

  • Ferritin is an evolutionarily conserved protein that plays an important role in iron storage and detoxification. In this study, the gene encoding a ferritin H subunit homologue (RbFH) was cloned from rock bream (Oplegnathus fasciatus) and analyzed at the expression. The full-length ferritin H cDNA was 1162 bp long and contained an open reading frame (ORF) of 531 bp that encoded 177 amino acid residues with a predicted molecular mass of 20.8 kDa. The 5' UTR was 297 bp in length, and the 3' UTR 298 bp, and preceded by a 5'-untranslated region that contains a putative Iron Regulatory Element (IRE). The deduced amino acid sequence of RbFH shares extensive sequence identities with the H ferritins of a number of fish species and contains the ferroxidase center that is preserved in ferritin H subunits. Examination of tissue specific expression indicated that RbFH expression was most abundant in PBLs, RBC, liver and muscle.

  • This paper presents the work of Southeast Asian scholar Ramon Guillermo. Using sophisticated computer-aided methods, Guillermo approaches a range of topics in the wide fields of social sciences and the humanities. A creative writer as well as an activist, Guillermo grounds his studies in nationalism and Marxism. Particularly interested in Indonesian and Philippine society and culture, Guillermo engages with the writings of labor leaders Tan Malaka and Lope K. Santos, translations of Marx's Capital into Bahasa and Filipino, and studies as well the discursive and historical connections between the Communist Parties of both countries. The paper aims to introduce the innovations of Guillermo's studies, particularly in the fields of cultural studies and translation studies. The type of cultural studies Guillermo practices is empirical, taking inspiration from innovations done in the digital humanities. Guillermo is most opposed to trendy, fashion-seeking approaches that are not grounded on history. He reserves particular ire for "hip" postcolonialism, and instead praises studies that are founded on politics and materialism. In translation studies, Guillermo goes beyond the mere cataloguing of mistakes. For him, it is the mistakes and "perversities" of a translation that is interesting and illuminating. Guillermo himself is a translator, and the paper ends with a brief discussion of his production in this field.
