In recent years continuously increasing number of tuberculosis (TB) cases due to the emergence of strains with multidrug resistance and AIDS is a significant global health problem. Therefore, more rapid and reliable diagnosis of TB may be one of the most urgent needs in efforts to eradicate the disease. The present study was designed to compare and assess the diagnostic values and efficiencies between the conventional methods (X-ray, AFB stain and culture) and PCR for pulmonary TB on 171 cases. Chest X-ray finding and clinical features revealed that 39 (22.8%) of 171 sputum specimens were pulmonary TB cases. The statistical data were taken on the basis of the definitive diagnosis: In X-ray, overall sensitivity, specificity, efficiency and false positive and false negative incidence was respectively 69.2%, 87.1％, 83.0%, 12.9%, and 30.8％； 79.5%, 95.5%, 91.8%,4.6％ and 20.5％ in AFB-stain; 56.4%, 99.2%,89.5%, 0.8% and 43.6% in culture; 82.1%, 96.2%, 93.0%, 3.8% and 17.9% in PCR. PCR got a highest sensitivity and efficiency as well as a lowest false negative incidence. Culture had a highest specificity with a lowest false positive incidence. These results imply that PCR assay is fast, sensitive and efficient method for diagnosis of pulmonary TB. However, combined use of the conventional methods with thorough quality control may offer more opportunities for detecting Mycobacterium tuberculosis and diagnosting TB although they have some limits.

The pattern cases for Korean traditional socks are named "beoseonbongip" which means a pouch to keep patterns for making "beoseon". "Beoseon" is Korean traditional socks. This study is to identify characteristics of the pattern cases and to develop cultural products based on the unique characteristics of the pattern cases. One hundred fifty one photos of "beosonbongip" were collected and quantitatively and qualitatively analyzed. Seventy percent of them were made between Joseon Dynasty and 1960s. As a result, most of the collected pattern cases are rectangular and square shapes, red color, and silk fabrics, and sizes of them are from 9cm to 15cm. A few pattern cases with different sizes and colors were also observed. Most pattern cases were made by fixing two among four triangle pieces which made by folding four tips of a rectangular or square cloth and then puting a not or a loop on the remaining triangle pieces in order to open and close the pattern cases. In a small number of the pattern cases, three of the four pieces were fixed and a button, a bead, a broach, or two nots or two loops were put on the other piece for opening and closing. Products such as apparels, bags, pouches, frames, and key holders were made using "beoseonbongip" form and construction method. This shows that "beoseonbongip" is a useful motive for creative product development.

This study examines the types and forms of underwear worn during the Joseon Dynasty period, and the purpose of this study is to apply the Joseon underwear design elements into designs of modern clothes, and make clothes that have practical use. In addition, it examines natural dyeing in the production of works, using a dye that contains tannin to increase color fastness. This study, first, looked into the types of female underwear during the late-Joseon Dynasty period through literature research and literature study. Second, the study chose artificial silk material (rayon), which was applied with dye containing tannin, and then with indigo (Jjok) and a different dye. Also, the study tested color fastness by washing the material, and rubbing fastness was tested if the material was either dyed with indigo. if it was dyed first with dye stuff containing tannin, and then with indigo dyeing color. Third, using the underwear types in the Joseon Dynasty period, the study developed and produced a dress, a skirt and pants that could be worn in modern life on a daily basis by applying Mujigi-chima (underwearskirt), Dan-sokgot (slip), Salchang-gojaengi (loosedrawers) and Sok-baji (bloomers) forms. Dresses applying underwear skirt using naturally-dyed artificial silk, dresses applying Salchang-gojaengi, dresses applying Dan-sokgot, skirt without a crotch designed in the form of pant swith an open crotch, and pant skirt with a crotch-applying pants with an open crotch were produced. In the future, hopefully, various studies of collaborations of Korean traditional clothing, and natural dyeing will continue to kee) the tradition alive.

Purpose : To determine the incidence and prognostic effect of p53 expression in patients with advanced supralottic cancer. Materials : Twenty-one cases of total 48 advanced supraglottic cancer patients who received postoperative adjuvant radiation therapy were evaluated by immunohistochemical staining employing p53 monoclonal antibody. Result : Three out of six stage III patients and four out of fifteen stage IV patients showed p53 expression without statistically significant difference (p=0.608). Five year survival rates are $93\%$ in p53 negative, $80\%$ in p53 positive patients and there was no significant difference(p=0.776). p53 expression does not show statistically significant correlation with primary tumor status(p=0.877), lymph node status(p=0.874) and age(p=0.64). Conclusion : There was no statistically significant correlation between traditionally known risk factors and p53 expression.

The purpose of this study was to investigate the probiotic properties of lactic acid bacteria (LAB) isolated from a Korean traditional food kimchi. Gram staining was performed by Macrogen (Macrogen, Inc.) for identification of the LAB. Five strains of LAB were identified, including DKGF9 (Lactobacillus plantarum), DKGF1 (L. paracasei ), DKGF8 (L. casei ), DK207 (L. casei ), and DK211 (L. casei ). The biological activities of the isolated strains were assessed. The results showed that heat resistance of the strains was similar to or higher than the commercial strain L. acidophilus LA-5. Indirect testing of the ability of the strains to attach to the mucin layer revealed that DKGF9, DKGF1, and DKGF8 have high binding affinities for the mucous layer. All strains showed antimicrobial activity similar to or higher than the commercial strain LA-5. In proteolysis experiments, the diameters of proteolysis zones of the five strains increased in the period of 24-72 h, with DKGF1 exhibiting the largest zone diameter. Three strains were selected based on their antioxidant activities. Among the five isolated strains, L. paracasei DKGF1 showed potential probiotic activity, and thus, it may be useful for the development of health-promoting products.

'Fleeting fragrance: the history, preservation and display of perfumed clothes' Fragrance - like style - is one of the intangible aspects of costume history that we often wish had been preserved. Garments were perfumed both to impart a pleasurable impression and to mask disagreeable odors from use or from production processes such as tanning and dyeing. Expensive gloves were traditionally perfumed, as well as lace collars, silk stockings and shawls. Both historical and modern attempts have been made to create scents that please the wearer and attract the oppoiste sex, while (preferable) also repelling osquitoes and moths! Unintentional perfuming also occurred, which we sometimes may be lucky to find in our museum collections. How do we describe and identify the transient odors of museum objects, and at what cost can they be preserved and presented for the public? This lecture includes samples of reconstructed historical scents presented in costume exhibitions at the Royal Danish Collections.

To develop the traditional tea culture into tourism product, we will review the characteristics of traditional tea culture. Since our ancestor introduced tea, our tea culture has expressed the culture and spirit of ancestors' life and practiced the body and mind. Based on this facts, we want to build the program for applying.the tea culture into the characteristics of tourism products. The program for tea culture is following; reception; visiting the Korean Tea Museum consisting of reception room, tea-related document room, tea pottery room and korean traditional dress room; experiencing tea ceremony, tea traditional foods, natural dyeing, tea pottery making and tea etiquette; seeing visitors out. However, we didn't evaluate the satisfaction of tourists from Japan, China, America and Europe who participated in this program through the objective data. But they understood the excellency and creativity of Korean traditional culture through experiencing Korean invisible-visible culture. Therefore this study intends to develop the program for the attractive and differentiated culture tourism and build the competitive model of Korean culture tourism product.

자원식물은 인간의 천연물에 대한 관심 고조와 미래 생물자원으로서의 경제적 가치가 재인식되어 미국을 비롯한 선진국은 오래전부터 유용한 식물자원 보존과 이를 이용한 산업화에 정부가 앞장서 추진하고 있다. 더욱이 우리나라는 국토면적에 비해 많은 식물종이 분포하고 뚜렷한 4계절과 다양한 토양특성으로 우수한 기능성식물자원이 많으며 이들 식물자원의 이용과 효능에 대한 풍부한 지식이 전통적으로 이어져 왔다. 그럼에도 불구하고 우수한 자원식물에 대한 보존과 이용이 과학화 체계화되지 못하여 세계적인 품종이나 제품개발은 미흡한 실정이다. 그동안 우리나라는 토종자원에 대한 관심과 꾸준한 연구개발로 농촌진흥청 보존 농업유전자원은 세계 6위 수준('10년말 291천점) 이며, 멀티기능 유용물질 함유 작물 개발 및 실용화 기술수준도 기술력 지수 세계7위로 높게 평가되고 있다. 그러나 이들 자원식물로부터 유용물질을 이용하여 세계시장을 선도하는 천연물신약, 건강기능성식품, 한방화장품, 천연 색소 및 향료 등의 제품개발은 미흡하여 앞으로 유망 자원식물을 이용한 체계적이고 과학적인 고부가 산업 육성을 위한 집중적인 투자가 필요한 시점이다. 자원식물을 이용한 천연물 신약개발은 고부가가치 제품과 산업재산권 확보가 가능하므로 수입 대체와 기술 및 제품수출이 충분히 이루어질 수 있다고 보여 현재 연구개발 중인 신약후보 도출 및 임상개발 과제의 수요를 반영한 후 단계별 대규모 신약개발 노력이 필요하다 하겠다. 건강기능 식품 개발은 고령사회 진입과 노령인구 증가로 노화억제 및 고령자 건강유지용 식품비중이 지속적으로 높아질 것으로 추정되어 약용식물을 소재로 개인 맞춤형 나노바이오 건강기능성 식품 개발을 통한 다양한 제품개발이 요구된다. 또한 우리나라 화장품분야의 전반적인 기술수준은 세계최고 기술의 62% 수준이나 화장품 소재의 자원식물 발굴과 나노기술 접목을 통한 효능의 극대화는 소비자의 웰빙 트랜드와 외국화장품과의 차별화 전략에 맞물려 국내 한방화장품의 세계화가 가능한 품목 중 하나이다. 식용 및 염색용 색소도 자원식물이 풍부하고 천연색소 시장이 크게 확장되고 있어 자원식물 중 경제성과 기술적 개발 가능성을 고려하여 단계적인 개발이 요구된다. 특히, 우리의 식물자원, 전통지식, 과학기술이 통합되어 효능을 현저하게 상승시키는 천연물신약, 건강보조식품, 화장품 등이 개발된다면 세계시장을 선도할 날도 멀지 않을 것으로 기대한다.
