Japanese Conceptions of Privacy: An Intercultural Perspective

This paper deals with intercultural aspects of privacy, particularly with regard to important differences between Japanese and the Western views. This paper is based on our discussions with Rafael Capurro – a dialogue now represented by two separate but closely interrelated articles. The companion paper is broadly focused on the cultural and historical backgrounds of the concepts of privacy and individualism in “Western” worlds; our main theme focuses on different concepts of privacy in Japan and their sources in related aspects of Japanese culture. The interrelationship between our two papers is apparent in our taking up identical or similar topics in each paper. Reading our two papers in conjunction with each other will bring about deeper and broader insights into the diverse values and worldviews of Japan and Western cultures that underlie concepts of privacy that at a surface level appear to be similar     

Cerebrospinal fluid free sialic acid and aspartate transaminase levels in meningitis

Background  Sialic acid (SA) is a nine carbon sugar derived from mannosamine and pyruvate. High levels of sialic acid and aspartate transaminase (AST) levels in cerebrospinal fluid have been described in pyogenic meningitis (PM) compared to tubercular meningitis (TBM). Objectives  To evaluate the levels of CSF free SA in PM and TBM and to assess the correlation between CSF free SA and CSF glucose or total protein levels. Patients and Methods  A total of 122 subjects were studied and divided into children and adults. Further, these have been subdivided into controls, PM and TBM. CSF free SA was estimated by thiobarbituric acid assay of Warren and AST by Reitmann and Frankel method. Results  CSF free SA and AST levels in children and adults were significantly high in PM (p<0.001) as compared to TBM and controls. Conclusion  A very high CSF free SA and AST were found to be characteristic of PM, making them useful parameters to differentiate PM from TBM.

Enhanced anti-proteases in<Emphasis Type="Italic">Labeo rohita</Emphasis> fed with diet containing herbal ingredients

Aqueous root extract ofAchyranthes aspera was incorporated in the experimental diet ofLabeo rohita (rohu). Control diet was prepared without root extract. Feeding of fishes with experimental diet has significantly (p<0.05) enhanced the serum anti-proteases level than fishes fed with control diet.     

Effect of<Emphasis Type="Italic">Vitex negundo</Emphasis> leaf extract on the free radicals scavengers in complete Freund's adjuvant induced arthritic rats

The effect of the oral administration ofVitex negundo leaf extract on the levels of enzymic and non-enzymic antioxidants were studied in the adjuvant induced arthritic (AIA) rats The levels of antioxidant enzymes such as SOD, CAT, GPx, G6PD, GSH and Vit-C were estimated in various groups of the experimental rats. It was observed that the antioxidant enzyme levels in the AIA were significantly low when compared to normal rats. A significant decrease in enzymic antioxidant—SOD, CAT, GPx, G6PD and non-enzymic antioxidant—GSH, Vit-C were observed in the liver of AIA rats compared to the normal rats. These results suggest that the leaf extract ofVitex negundo possesses antioxidant activity.     

Privacy. An Intercultural Perspective

This paper deals with intercultural aspects of privacy, particularly with regard to differences between Japanese and Western conceptions. It starts with a reconstruction of the genealogy of Western subjectivity and human dignity as the basic assumptions underlying Western views on privacy. An analysis of the Western concept of informational privacy is presented. The Japanese topic of ‘‘denial of self” (Musi) as well as the concepts of Seken, Shakai and Ikai (as analyzed by the authors of the companion piece on privacy in Japan) give rise to intercultural comparisons. The paper addresses the question of privacy in cyberspace and mass media. Finally the question of freedom of speech is related to the Japanese concepts of Ohyake and Watakusi.     

Microscopic haematuria as an occult filarial infection in bhubaneshwar an endemic area for bancroftian filariasis

Sera samples of 7 microscopic haematuria cases collected before and after treatment with Diethylcarbamazine citrate, (DEC), 9 microfilaraemic cases and 19 endemic normal individuals were analysed for filarial antigen and IgG antibody levels. Filarial antigen was detected in 5 of the 7 microscopic haematuria cases, of which 3 turned negative for antigen after treatment with DEC. While none of the 7 haematuria cases were positive for filarial IgG antibodies, before the DEC treatment, all of them turned positive after DEC treatment. The sensitivity and specificity values(to detect mf +ve cases) were 89% and 90% respectively for the detection of filarial antigen and 78% and 95% respectively for the detection of filarial IgG antibodies.     

基于MODIS数据的泰国林地资源提取

遥感技术的发展为我们对世界资源的研究提供了新的手段,克服了世界资源研究过程中数据缺乏的困难。泰国曾经是林地资源丰富的国家,尤其是热带林地资源,但是近几十年来林地面积在不断减少,带来了一系列生态问题。选用MOD09Q1的1、2波段,MOD09A1的第6波段以及MOD11A2数据产品提取了泰国林地分布情况。由于泰国地处热带地区云雾噪音为林地的提取造成了很大的不确定性,为了有效去除云雾噪音影响,结合NDVI、NDSI、LST多参数在林地提取中的优势对泰国林地进行提取。采用泰国2003年统计年鉴提供的分省林地面积以及2003年p131r47和p131r48共2景ETM影像进行了精度验证。结果表明,利用多参数综合分类方法对林地提取精度较高,通过与2003年统计年鉴数据进行回归分析发现二者存在明显的线性关系,决定系数达到0.9264。     

国外四大医学期刊富媒体数字内容开发现状及对国内医学期刊的启示

【目的】 探讨我国医学期刊在富媒体数字内容开发方面的有效路径。【方法】 以《新英格兰医学杂志》《柳叶刀》《美国医学会杂志》《英国医学期刊》四大医学期刊网站富媒体数字内容为主要调研对象,结合国内医学期刊现状以及笔者所在编辑部实践情况,分析探讨我国医学期刊富媒体数字内容开发现状。【结果】 随着数字化出版革命的不断演进,富媒体内容已经成为四大医学期刊数字内容增值服务的重要部分,具有如下特点：均较早地引入专家视频、音频访谈内容;越来越多的文章以富媒体形态出版;对期刊学术资源进行二次加工,推出多种交互式产品;出现视频形态的“文章”;信息图得到广泛应用;部分资源通过付费订阅等方式开辟新的营收途径。国内医学期刊数字化发展还处于初级阶段,富媒体内容开发能力薄弱,应当从加强集约化经营、重视专门人才的引进以及培养、充分发掘自身特色资源等方向入手,增强富媒体内容的开发能力。【结论】 国内医学期刊应当学习借鉴四大医学期刊在富媒体内容开发方面的先进经验,结合实际情况和自身特色,提高富媒体内容开发能力,更好地促进学术影响力的提升,创造更大的社会效益和经济效益。     

Immunoproteomic analysis of secretory proteins ofAspergillus fumigatus with specific IGE immunoreactivity

Allergenic/antigenic proteins are known to induce Type I and Type III hypersensitivity reactions leading to allergic bronchopulmonary aspergillosis (ABPA) in immunocompetent host. The common structural features or intrinsic properties of the allergens/antigens leading to allergenicity in a host are not well understood. In the current report, comparative analysis of proteins on two dimensional gel electrophoresis (2D-3) and specific IgE immunoblots ofA. fumigatus secretory proteins (1^st, 2^nd and 3^rd week culture filtrate proteins) was carried out. We observed a total of 159 proteins in 1^st, 2^nd and 3^rd week culture filtrates ofA. fumigatus. Specific IgE immunoreactivity was observed in 75 proteins with different intensity. Third week culture filtrate showed maximum number of proteins, 142, and specific IgE immunoreactive proteins, 65. MALDI-TOF analysis resulted in putative identification of two allergens as hypothetical protein YBL057c fromSaccharomyces cereviseae and unnamed protein product fromDebaryomyces hansenii (similar to IPF14568 ofCandida albicans). Identification of a repertoire of specific IgE immunoreactive proteins will facilitate the studies on structure-function relationship of these proteins relevant for diagnosis and pathogenesis.
