  • Malignant pleural mesothelioma (MPM), an aggressive malignant tumor of mesothelial origin associated with asbestos exposure, shows a limited response to conventional chemotherapy and radiotherapy. Therefore, the overall survival of MPM patients remains very poor. Progress in the development of therapeutic strategies for MPM has been limited. We recently reported that the calpain inhibitor, calpeptin exerted inhibitory effects on pulmonary fibrosis by inhibiting the proliferation of lung fibroblasts. In the present study, we examined the preventive effects of calpeptin on the cell growth of MPM, the origin of which is mesenchymal cells, similar to lung fibroblasts. Calpeptin inhibited the proliferation of MPM cells, but not mesothelial cells. It also prevented 1) the expression of angiopoietin (Ang)-1 and Tie-2 mRNA in MPM cells, but not mesothelial cells and 2) the Ang-1-induced proliferation of MPM cells through an NF-kB dependent pathway, which may be the mechanism underlying the preventive effects of calpeptin on the growth of MPM cells. These results suggest potential clinical use of calpeptin for the treatment of MPM.

  • Antimutagens, including diverse compounds of botanical origin, offer some promise of reducing the risk posed by exposure to mutagens. Caution is warranted, however, as there may sometimes be a delicate balance between antimutagenic effects and potentiating effects of the same compounds. We studied effects of the antimutagens spermidine (SPD) and cysteamine (CSM) on the genetic activity of the radiomimetic cancer chemotherapy drug bleomycin (BLM).(omitted)

  • At local, galaxy properties are well known to be clearly different in different environments. However, it is still an open question how this environment-dependent trend has been shaped. In this presentation, we will show the results of our investigation about the evolution of star-formation properties of galaxies over a wide redshift range, from z~2 to z~0.5, focusing its dependence on their stellar mass and environment. In the UKIDSS/UDS region, we estimated photometric redshifts and stellar population properties, such as stellar masses and star-formation rates, using the deep optical and near-infrared data available in this field. Then, we identified galaxy cluster candidates at z~0.5-2. Through the analysis and comparison of star-formation (SF) properties of galaxies in clusters and in field, we found interesting results regarding the evolution of SF properties of galaxies: (1) regardless of redshifts, stellar mass is a key parameter controlling quenching of star formation in galaxies; (2) At z<1, environmental effects become important at quenching star formation regardless of stellar mass of galaxies; and (3) However, the result of the environmental quenching is prominent only for low mass galaxies (M* < $10^{10}M_{\odot}$) since the star formation in most of high mass galaxies are already quenched at z > 1.

  • The purpose of this study was to develop the couple relationship improvement program for college students and to examine the effects of the program based on the family of origin and attachment. Does based on Bowen's theory of differentiation of self, adult attachment, group counseling for this and establishes program goals according to systematic group counseling program development model and composed program. In order to attain like this research objective, six male and female couples attending colleges were divided into the participating group and comparison group; the students were from H University in Daejeon, Korea, and they had the experience of participating in the comprehensive group program. The changes shown by the couples were studied, and the cases were analyzed by examining the minutes and reports, which supplemented the quantitative analysis of the effectiveness of the group counseling program. The analysis of the effectiveness of the program showed the following. The case showed that goals of the individuals and couples, enhancing the understanding of self and partners by understanding the self-differentiation and adult attachment while having a positive impact on understanding, acceptance, disclosure of self partner and couple relationship based on the social support of the cognitive emotion regulation strategies.

  • A least squares regression interval mapping model was derived to detect quantitative trait loci (QTL) with a unique mode of genomic imprinting, polar overdominance (POD), under a breed cross design model in outbred mammals. Tests to differentiate POD QTL from Mendelian, paternal or maternal expression QTL were also developed. To evaluate the power of the POD models and to determine the ability to differentiate POD from non-POD QTL, phenotypic data, marker data and a biallelic QTL were simulated on 512 F2 offspring. When tests for Mendelian versus parent-of-origin expression were performed, most POD QTL were classified as partially imprinted QTL. The application of the series of POD tests showed that more than 90% and 80% of medium and small POD QTL were declared as POD type. However, when breed-origin alleles were segregating in the grand parental breeds, the proportion of declared POD QTL decreased, which was more pronounced in a mating design with a small number of parents ($F_0$ and $F_1$). Non-POD QTL, i.e. with Mendelian or parent-of-origin expression (complete imprinting) inheritance, were well classified (>90%) as non-POD QTL, except for QTL with small effects and paternal or maternal expression in the design with a small number of parents, for which spurious POD QTL were declared.

  • Lactic acid bacteria (LAB) Play an important role in the human diet and are used in the production of edible fermented products such as kimchi and yoghurt. LAB are regarded as safe food additives used to enhance the nutritive value of foods. Plant-origin lactic acid bacteria (PLAB) cultured in vegetal media are now widely used in food industries. PLAB have been found to activate intestinal immunity, modulate the balance of the intestinal bacterial from, and enhance intestinal function. They are known for their strong resistance to acid; this enables them to persist for a longer duration in the human intestine. PLAB can also survive in the intestinal environment under conditions of poor nutrition. They have stronger vitality as compared to LAB of animal origin. Due to the unique characteristics of PLAB, they are being widely used in Japan for processing foods such as yoghurt and beverages. Recently, PLAB has also been used as the culture for processing yoghurt in Korea. We expect further research on the functional effects of PLAB.

  • 샌드파일 공법은 연약지반 개량을 위해 널리 사용되는 방법중의 하나이다. 샌드파일 설치에 의해 얻고자 하는 주된 목적은 압밀촉진에 있으나 이와 더불어 복합지반효과를 지니게 된다. 본 연구에서는 상대적으로 면적 치환비가 작은 연직배수재로서 적용된 샌드파일 설치지반에서의 복합지반효과를 파악하고자 하였다. 이를 위하여 원지반과 샌드파일의 지내력 확인을 위한 평판재하시험을 실시하였으며, 성토체와 지반과의 상호거동을 확인하기 위하여 토압계를 설치하여 계측관리를 실시하였다. 분석결과 면적치환비가 작은 샌드파일 설치지반에서 복합지반을 고려한 지지력은 원지반의 지지력과 비교하여 매우 작은 증가효과를 보였다. 그러나 원지반과 비교한 샌드파일 설치위치에서의 지지력 증가는 약 60% 로 나타났다. 이와 같이 샌드파일의 강성증대에 의한 파일설치 위치에서의 지지력 증대는 재하하중 작용에 의한 압밀진행 과정중 압밀특성 변화의 요인으로 작용하게 될 것이다. 따라서 샌드파일 강성증대에 따른 복합지반효과는 샌드파일 설치지반에서 압밀침하량이 감소하는 요인으로 평가될 수 있는 것으로 판단된다.
