Background : Isoniazid (INH) is one of the most effective anti-tuberculosis (TB) drugs. In Korea, the dose of INH normally used in patients over 50 kg is 400 mg/day, which differs from the dose recommended by other countries. Indeed, the metabolism of INH shows ethnic variations, and Koreans are predominantly rapid acetylators. However, two reports suggested 300 mg of INH might be sufficient to reach an ideal peak level in Korean patients over 50 kg. Therefore, the aim of this study was to compare the effectiveness and adverse reactions between INH 300 mg and 400 mg in Korean TB patients. Method : Patients who were culture-positive, susceptible to all 1st-line drugs, initially on HREZ, and weighed over 50 kg were selected from patients with pulmonary TB between April 2003 and March 2005. The treatment results and adverse reactions in the INH 300 mg and 400 mg group were compared. Since April 2004, most TB patients at Asan Medical Center were administered INH 300 mg irrespective of the body weight. Results : The study included 123 patients in the 300 mg INH group and 128 in the 400 mg INH group. There were no significant differences between the groups in terms of age, gender, weight, history of TB treatment, initial smear strength, and frequency of cavitary lesions. There was no difference in the treatment duration between the groups. One hundred eleven (90%) patients in the INH 300 mg group and 102 (80%) in the INH 400 mg group completed treatment (p>0.05). There were no differences in the frequency of modification of the initial regimen between groups due to any adverse reactions (300 mg : 9.0%, 400 mg : 13.7%) and hepatotoxicity (300 mg : 2.7% ; 400 mg : 7.8%). Conclusion : Considering treatment results and adverse reactions of two groups, 300mg of INH may be sufficient for treating Korean TB patients. Further studies comparing the frequency of relapse will be needed.

Purpose: Glycogen storage disease type Ia (GSD Ia) is an autosomal recessive disorder of glycogen metabolism caused by glucose-6-phosphatase (G6Pase) deficiency. The clinical manifestations of G6Pase deficiency include growth retardation, hepatomegaly, hypoglycemia, lactic acidemia, hyperlipidemia and hyperuricemia. Many mutations of this gene have been found worldwide in various ethnic groups, establishing the molecular basis of GSD Ia. To elucidate a spectrum of the G6Pase gene mutations in Korean, we analyzed mutations in Korean patients with GSD Ia. Methods: Both alleles of 9 unrelated GSD 1a patients were studied by PCR and direct DNA sequencing methods. In all patients, GSD 1a was diagnosed by the enzyme assay for the liver biopsy specimen. Results: In Korean, the most prevalent mutation was g727t substitution in exon 5, which has been reported to cause abnormal mRNA splicing: Sixteen out of 18 alleles were found to have this mutation. In addition, we identified one novel mutation, a c611g, converting a proline to an alanine at codon 178. Conclusion: Our findings suggest that a screening for the g727t mutation by noninvasive molecular method can detect most cases of GSD Ia in Korean patients.

Background: Host genetic polymorphisms in the HIV-1 co-receptor CCR5 and CCR2b and SDF-1, ligand for co-receptor CXCR4, have been known to be associated with the resistance of HIV infection and/or the delayed disease progression in HIV-infected patients. Methods: We examined the frequencies of SDF1-3'A and CCR2b-64I alleles of 354 Koreans including 100 HIV-uninfected persons, 13 discordant spouses of HIV-infected persons, and 241 HIV-infected persons. The genotyping assays of SDF1 and CCR2b genes were carried out by polymerase chain reaction-restriction fragment length polymorphism. Results: The frequencies of CCR2b-64I and SDF1-3'A alleles in Koreans were very high compared with Caucasians and blacks. Observed frequencies of CCR2b-64I and SDF1-3'A allelic variants were 25.1% and 28.7%, respectively. The frequency of the CCR2b-64I allele in Koreans was 2~4 times higher than those of other ethnic groups with the exception of Asian. The frequencies of CCR2b-64I and SDF1-3'A genotypes did not show the significant difference between HIV-infected and uninfected Koreans. However, the prevalence of CCR2b-64I genotype of the LTNP group was about two times higher than that of the remainder group (P< 0.05). Four (45%) out of 9 LTNPs (long-term nonprogressors) showed having the SDF1-3'A allele and 7 (78%) out of 9 LTNPs carried the CCR2b-64I allele. 3 (33%) out of 9 LTNPs had both SDF1-3'A and CCR2b-64I alleles. But none of 5 RPs (rapid progressors) appeared to have both SDF1-3'A and CCR2b-64I alleles. Conclusion: The different genetic backgrounds in study populations may affect the disease progression and the AIDS epidemic in each country. Further studies need to define whether high frequencies of CCR2b-64I and SDF1-3'A allelic variants may affect the HIV disease progression.

Background: It is known that obesity is one of the risk factors for breast cancer although the association may differ between ethnic groups and with the menopausal status. Recently obesity-related risk factors including serum adiponectin and insulin levels have been analyzed together with BMI in association with breast cancer risk. Materials and Methods: We measured serum high molecular weight (HMW) adiponectin and insulin levels in a hospital based case-control study, including 66 sets of Japanese female breast cancer cases and age and menopausal status matched controls. Serum levels of HMW adiponectin, insulin levels and body mass index (BMI) were examined in association with breast cancer risk with adjustment for the various known risk factors by menopausal status. Results: Women in the highest HMW adiponectin levels showed significant reduced risk of breast cancer in both pre and postmenopausal women (odds ratio (OR), 0.01; 95% confidence interval (CI), 0.00-0.26 and 0.13; 0.03-0.57, respectively). Lower BMI showed decreased breast cancer risk in both pre and postmenopausal women (OR, 0.04; 95% CI, 0.00-0.69, OR, 0.28; 95% CI, 0.07-1.11, respectively). Conclusions: These results indicated that higher serum HMW adiponectin levels and lower BMI are associated with a decreased breast cancer risk in both pre and postmenopausal women in Japan, adding evidence for the obesity link.

In this paper, through the mutual interpretation and verification of the ancient Korean history books with different origin that have been suspected as false documents, it proves that they could be logically real records and reveal that the substance of the legendary 'medicine for anti-aging and longevity', which also had been mentioned in Chinese old books, is Korean ginseng. Furthermore, with reference to the modern Y chromosomal map of the migratory routes of mankind corresponding to these routes recorded in 「Budoji」, the core history book, the formation of the four ethnic constitution groups (Sasang Constitution) based on the life style of each human group has been estimated. And the cause of Korean ginseng with fever problem for Southeast Asians is their pharmacogenomic constitution problem by protopanaxatriol (PPT) type ginsenosides in ginseng. It was resolved with over production of protopanaxdiol (PPD) type ginsenosides against PPT type in Korean red ginseng as historical or scientific point of view. In addition, by explaining that the processing method to Korean red ginseng could increase red ginseng acidic polysaccharides (RGAP), the RGAP, PPD type ginsenosides, and arginine which is originally abundant in Korean ginseng could increase the expression of the 'heat shock proteins' as a kind of chaperone in the body, this paper presents the theory allowing the scientific interpretation of the efficacy of Korean red ginseng as an 'adaptogen' or 'medicine for anti-aging and longevity'. Lastly, through the consideration of the growing environment of American ginseng and Korean ginseng, the differences are presented.

Many ethnic groups have different cultural backgrounds and each culture has developed with its own traditions. The interaction between different cultures is getting more active through acculturation and cultural contact. The purpose of this study was to provide basic data about the domestic living of Australians in order to compare with Korean immigrants in the form of a Cross-Cultural study. For this, usage of domestic space and seating style of 53 Australian households in Melbourne were analyzed. Ethnographic research with questionnaire was used. The results of the research were as follows. 1. The open plan type combining the kitchen, dining and tying areas was the most popular one for Australians and they are very satisfied with that type. 2. The laundry room has been planned traditionally and Australians demand to be able to dry their laundry and do ironing in there additionally. Most of Australians were satisfied with separated toilet and bathroom. h drain hole on the floor of the bathroom was not essential for most Australians. 3. Australians were doing various activities in the living areas and they also enjoy gelling together in the kitchen and dining areas. 4. The seating style of Australians was generally the chair-seating style. However, they sometimes made a bed for guests on the floor and watched TV and treated guests with both chair seating style and floor seating style. 5. Australians were satisfied with using carpet presumably for its warmth.6. Many Australians took off their shoes inside of the house for hygienic reason. Most people organized the shoes in the cabinet of the bedroom. 7. The most popular heating system was ducted heating for Australians and they were very satisfied with it because it was suitable for the weather in Melbourne. 8. The living room was the most important one for Australian families and they thought that it should be decorated well for entertaining guests. It was also considered that brightness of the light was enough for most Australians.

The purpose of this study was to approach to the internal meanings included in the Happening and the culture of hippies, by analysing the basic mental conditions in the process of the Happening. And this study was composed of the concept and the development of Happening, the characteristics of the hippies that related in the midst of the happening's background, and the formativeness between these factors and hippies'fashion. Since the happening a genre of fine arts expression attended the New School for social research in New York in 1954, Allan Kaprow direct-influenced by John Cage used the word 'Hapening'first, practicing '18 Happenings in 6 parts'at the Rueben gallery in 1959. Kaprow's 18 Happenings was one of the earliest opportunities for a wider public to attend the live events that several artists had performed more privately for various friends. Despite the very different sensibilities and structures of artist's works, artists were all thrown together by the press under the general heading of 'Happening', following Kaprow's 18 Happenings. Being considered as the root of the Happening 'Expression of Sound'of John Cage was the discovery of the exisiting thing- the Happening. Most artists were to be deeply influenced by Cage's theories and attitudes-that is, his sympathy for Zen Buddihism and oriental philosophy-and by reports of the Black Mountain events. These events would directly reflect contemporary painting and stemmed from the Futurists, Dadaists and Surrealists. And Happening's development background was based on the culture of hippies. Swinging London had been under the sway of psychedelic drugs and utopian visions of 'hippie'wave sweeping in from Califonia. This wave, which affected solid middle-class youth first and formost, began in Haight Ashbury in San Francisco. Without dwelling on the hippie movement here, it is worth nothing that it resulted from the convergence of several undercurrents : consciousness-expending drugs, the anti-Vietnam war developments, the impact of English pop groups on American music and the rise of protest songs, and finally the beatnik tradition of non-conformism. Hippie culture and its pursuit of love, peace and psychedelia was the antitheses of 1960s main street fashion. The media gave everyone with long hair the label of 'hippie', but it was always a very loose collage of attitudes and styles. The rejection of sexual taboos was conveyed by the hippie's refusal to wear. Although the bold exposure of body raised controversies because it went against the existing moral values, it has a significant implications. Psychedelics brought mind-expansion and the possibillity that modern technology (light show, synthesized electronic sounds), new fabrics or colors, and LSD could be utilized to provide an escape route from the dreariness of modern life. During the 1960s, traditional costumes, many of which had never been seen outside their native regions, became sought after and adopted in the West, initially by the young, who wanted to demonstrate their solidarity with cultures uncontaminated by mass industry. The most ardent proponents of such folk costumes were the hippies. Hippies dress was sometimes decribed as 'anti-fashion', produced by a patchwork of ragged cast-offs and flamboyant accessories, of outmoded Western dress and time-honored ethnic garments all combined, modified and permutated into variety of personal statements. 'Flower Power'became a reality. From the results of this study, we can see the expanding trend of the influence and the concept of the sew art genre 'Happening'in the formativeness as well as the fine arts field.

The Wiener Werkstatte created the most avangarde textile designs in Europe at the end of the 19th and the beginning of the 20th century. This study is to examine the distinctive characteristics of the textile design of the Wiener Werkstatte. The purpose of this study is to analyze the textile designs of the various designers who had contributed to shape the characteristics of the Wiener Werkstatte at various stages, and to catagorize the designs according to the subject matter, the design sources, the layout, the design principles, and the usages. The textiles of the first half of the Wiener Werkstatte are wovens for the homefurnishings. They were used as upolsteries. Wall coverings, and curtains in the commissioned buildings and houses which Hoffman designed and built in conjunction with the Wiener Werkstatte. The designs of this period have the simple and bold characteristics using less then three colors in a design. The subject matters used in the designs are firstly, stylized animals and plant forms; secondly, the purely geometric forms derived from the architural buildings. The textiles of the latter half of the Wiener Werkstatte put more emphasis on the printed textiles for the women's apparels. The textile designs of this period are categorized into four groups : firstly, the designs that stylized plant forms ; secondly, reinterpretational designs; thirdly, ethnic designs : and fourthly, the geometric art deco designs. The number of colors used in a design range up to 7 colors and all over, stripe, and ogee layouts are used.

The 1900s in New Orleans, the harbor city, was indeed an era of confusion because there were various ethnic groups and races. Songs that had been sung by slaves taken from Africa, Black spiritual music, blues, British folk songs, French folk music, ballet music, Spanish dance music, and the march of military bands were mixed with Rag Time to achieve diversity. This developed the beginning of jazz. While swing jazz was most popular and loved by the public during the 20th century, the bebop preferred the small scale organization of musical instruments and developed as a form of jazz featuring the impromptu musical performances. Later, cool jazz, a new style involving the fast and complicated code progress, emerged with free jazz, which features the fundamental rupture from the tradition of the jazz. Miles Davis, who introduced the rock beat in jazz, started fusion jazz. Although jazz has been named differently depending on the era, the main attraction of jazz lies on improvisation. In other words, despite a small changes in code progress and rhythm, the most important thing the player considers is improvisation. Some famous players who lived in the same era followed the whole atmosphere but each had their own style. So, even when they did play the same song, they revealed their style in solo parts despite the same head.

Methylenetetrahydrofolate reductase (MTHFR) is an essential enzyme involved in folate metabolism; a single nucleotide polymorphism (SNP) C677T has been reported to be linked with altered incidences of several diseases. We here conducted a meta-analysis of 15 published epidemiological studies with a total of 7306 cases and 8062 controls to evaluate its association with prostate cancer risk with overall and subgroup analyses. No statistical relationship was found overall with any genetic model (TT vs. CC: OR = 0.80, 95%CI = [0.62, 1.04], P = 0.094; CT vs. CC: OR = 0.97, 95%CI = [0.84; 1.12], P = 0.667; Dominant: OR = 0.94, 95%CI = [0.82; 1.07], P = 0.343; Recessive: OR = 0.81, 95%CI = [0.64; 1.04], P = 0.104), but after the exclusion of several studies, we could observe the homozygote TT to confer less susceptibility to prostate cancer in carriers; moreover, different effects of the polymorphism on prostate cancer risk was detected from subgroup analysis stratified by participants' residential region: significant reduced prostate cancer risk was found to be associated with the polymorphism from Asian studies (TT vs. CC: OR = 0.47, 95%CI = [0.33; 0.67], P < 0.001; CT vs. CC: OR = 0.73, 95%CI = [0.60; 0.90], P = 0.002; Dominant: OR = 0.67, 95%CI = [0.56; 0.82], P < 0.001; Recessive: OR = 0.55, 95%CI = [0.40; 0.76], P < 0.001) while studies from Europe indicated a slight increased risk under dominant model with marginal significance (OR = 1.14, 95%CI = [0.99; 1.30], P = 0.064). Moreover, the protective effect of the polymorphism against prostate cancer was also shown by studies performed in yellow Asians (TT vs. CC: OR = 0.48, 95%CI = [0.31; 0.75], P = 0.001; CT vs. CC: OR = 0.68, 95%CI = [0.51; 0.90], P = 0.006; Dominant: OR = 0.63, 95%CI = [0.48; 0.82], P < 0.001; Recessive: OR = 0.57, 95%CI = [0.39; 0.84], P = 0.004). We propose that these phenomena should be viewed with the consideration of folate metabolism profile and different gene background as well as living habits of different populations, and more relevant studies should be conducted to confirm our hypothesis and provide a comprehensive and clear picture concerning this topic.
