The purpose of this study was to inves-tigate the economic performance of the textile industry for the Korean traditional clothes. The content of this paper had two pars; The first part was for the macroeconomic aspects such as location production employments and the produc-tion facilities of the textile industries. The second part was for the microeconomic aspects such as business type branding method fabric type R&D efforts sourc-ing and the distributional channel The major results were as follows: 1.) Most textile firms for the korean traditional clothes were located in Gongju for man-made fibers and in Jinju for silk fabrics. 2) The size of the textile industry in terms of the number of business produc-tion amount the number of employee de-creased during 1994 and 1995 due to the decreasing demand. 3) Over the half of the textile firms produced raw fabric products while only 20% of them were involved in additional dyeing and /or printing finish which re-sulted in low value added production 4) The R&D effort of the textile indus-try for the Korean traditional clothes was very low due to the market uncertainty lack of technological knowledge and most of all small size of the firms 5) Most raw materials for the textile in -dustry were imported with high(25%) tariff rates resulting in price increase and thus low competitiveness in the market. 6) The textile producers sole about the 70% of their products to the wholesalers while selling the rest to the retailers di-rectly. This showed the dual structure of the distribution channel in the textile products. These results suggested some implica-tions for the firms the policy makers and the researchers. The firms should develop new and improved products to increase and create consumer demand by intensive R&D efforts. The government policy ma-kers should give financial supports the firms with R&D investment and legal help such as lowing tariff rate for the raw ma-terials. The researchers from the academy could help the textile industry with the advanced technological knowledge and up-date information for the consumer fashion demand.

Osteosarcoma is the most common primary bony malignancy and its survivorship has been progressed markedly through refined chemotherapy and surgery. But still there are many non-responders and analysis of prognostic factors may be helpful for them. Two hundred and sixty-six patients were enlisted between Mar, 1985 and Sep. 1994. Among them our inclusion criteria were: 1)primary, nonmetastatic classical osteosarcoma 2)extremity in location 3)no prior treatment at other institute and completed neoadjuvant chemotherapy and surgery according to our protocol. One hundred and eleven cases were eligible. Analyzed factors were:age, sex, location, tumor size, and pathologic response. Statistical methods were log-rank test for univariate and Cox's test for multivariate analysis. Male to female ratio was 69:42 with an average age of 17.2 years. Locations of tumor were distal femur 59, proximal tibia 29, and proximal humerus 8. Tumor size were measured by its maximal diameter and 48 cases were above 10cm and 47 cases were below 10cm. For pathologic response, 57 cases showed more than 90% and 54 cases were less than that. Limb salvage procedure was 101 cases and amputation was 10 cases and their local recurrence rate were 3.6%. Average follow-up period was 24(9-78.2) months and their final status was CDF 86, AWD 8, NED 5, and DOD 12 cases. In univariate study: type of operation(p=0.005), tumor size(p=0.005), and pathologic response(p=0.02) were significant variables. Pathologic response(p=0.03) and type of operation(p=0.01) were meaningful prognostic factors on multivariate analysis. But the latter result was interpreted as a bias, so pathologic response remained as a sole meaningful prognostic factor. More aggressive chemotherapy will be needed to improve the survival.

Objectives : The aim of this study was to describe the details and to assess the clinical evidence of acupuncture and moxibustion for non-specific chronic neck pain. Methods : We searched seven databases including Korean, English, and Chinese databases through July 2016. Studies using acupuncture, moxibustion, pharmacopuncture, electroacupuncture, auricular-acupuncture, acupressure for non-specific chronic neck pain were included. Only controlled clinical trials or randomized clinical trials were assessed. Study design, number of subject, inclusion criteria, intervention, and results were extracted. In addition, details of intervention including needle type, retention time, acupoints were analyzed. Results : Total 64 studies(39 acupuncture, 9 laser, 6 pharmaco-acupuncture, 3 electro-acupuncture, 3 auricular-acupuncture, 3 moxibustion, 1 acupressure) were included. Among 39 acupuncture studies, 35 used acupuncture as sole intervention. Sham treatment was the most common intervention for control group, followed by no intervention. Various outcome including pain, disability, quality of life, range of motion was used as outcome measurement. The effect of acupuncture and moxibustion was different depending on the type of control and outcome measurement. The most commonly used method in acupuncture for neck pain was GB21, SI3, GB20, LI4, BL11 acupoints, 10~30 mm insertion depth, 20~30 retention time, and 1~2 times per week. Conclusions : Analyzing the details of acupuncture and moxibustion treatment could be helpful for researches and clinics.

Penicillium verruculosum을 xylan을 함유한 액체배지에서 26일간 배양하면서 xylan 분해활성도를 비롯한 몇 가지 변화를 관찰하였다. Xylan과 PNPX 분해활성도는 단백질량의 증가와 함께 배양 8일까지 급격히 증가하였으나 배양액 중의 환원당의 변화와는 비례하지 않았다. 배양 12일째의 배양상징 액을 탄소원으로서 cell-obiose octaacetate를 가한 배양상징액과 함께 전기영동하였을때 서로 다른 단백질 분포양상을 보였으며 본 배양상징액에 있어 섬유소 성분들에 대한 분해활성도는 거의 나타나지 않은 반면 xylan에 대해서는 매우 높은 활성도를 나타냈다. 배양 상징 액에 xylan을 가했을 때 반응 생성물로서 xylose와 xylobiose를 비롯하여 소당류들이 생성됨으로서 endo-type의 분해활성도로 추정 되었으며 이 때 xylobiose가 가장 많은 비율을 차지했다. Xylan과 PNPX분해 활성도에 대한 배양 상징액의 최적온도는 각각 50~6$0^{\circ}C$와 60~7$0^{\circ}C$였으며 최적pH는 각각 3.0-4.0과 4.0-5.0이었다.

Buddhist paintings in the late Joseon dynasty are characterized by diversification and subdivision of subject matters. Buddhist paintings rapidly declined since 19th century, being miniaturized and showing complicated composition. Figures that identified the shape of shoes in Buddhist paintings of late Joseon dynasty included sacheonwang that were placed in the left and right bottom of Buddhist paintings, sinjung, gwiwang and pan-gwan of siwangtaeng. Sacheonwang, an Indian folk god, was depicted as a noble person in "ahamgyeong", an early sutra, but was depicted as an armored warrior in Mahayana Buddhism world. The style of shoes sacheonwang in Korea were different depending on the times. The shoes of the sacheonwang sculpture in Seogguram of Shilla dynasty are sandal type. The sacheonwang that was drawn on Jijangbosaldo in Goryeo dynasty wears non-showy armor and red yi(履). The sacheonwang that was expressed on Buddhist paintings in Joseon dynasty wears showy armor and decorated hwa. Comparing the yi of Goryeo Jijangbosaldo sacheonwang with the yi of Bodhisattva on the Dunhuang yeolbanbyeonsangdo, Jijangbosaldo sacheonwang's shoes are Korean style in which the sole is flat and the front part has no decoration, but in the shoes of Bodhisattva on the Dunhuang yeolbanbyeonsangdo the sole is not flat, the front part is lifted. The style of shoes of pan-gwan, who is depicted on Siwangtaeng, is hwa. However, unlike the decorative hwa of sacheonwang, its front is not lifted and it has no decoration. It is assumed that the shoes of sacheonwang or pan-gwan represented obangsaek based on the idea of eumyang-ohaeng. Depiction of shoes shown in Buddhist paintings reflected the phases of the social life. In addition, the sandals of Shilla sacheonwang implies that sourthern culture in addition to Buddhism was introduced. Having expressed the shoes of Goryeo sacheonwang with conventional yi implies that Buddhism governed the inner world of the people, and the shape and material of the shoes reveals aristocracy. It is assumed that that an armored warrior wore yi, not hwa implies that the then society was stable. Also, it is assumed that that the shoes of sacheonwang on Buddhist paintings in Joseon dynasty were hwa implies that the role of tutelary god was stressed in the disordered society.

It is likely that maltose could provide a good substrate for the bacteria in the intestine, when the pathogenic bacteria invade and colonize in human gut. For better understanding of this organism's maltose metabolism, a mutant that was not able to grow with maltose as a sole carbon source was screened from a library of mutants constructed by a random transposon mutagenesis. By a transposon-tagging method, malPQ genes encoding a maltodextrin phosphorylase and a 4-${\alpha}$-glucanotransferase, were identified and cloned from Vibrio vulnificus. The deduced amino acid sequences of malPQ from V. vulnificus were 48 to $91\%$ similar to those of MalP and MalQ reported from other Enterobacteriaceae. Functions of malPQ genes were assessed by the construction of mutants whose malPQ genes were inactivated by allelic exchanges. When maltose was used as the sole carbon source, neither malP nor malQ mutant was able to grow to a substantial level, revealing that the MalP and MalQ are the only enzymes for metabolic utilization of maltose. The malQ mutant exhibited decreased adherence toward intestinal epithelial cells in vitro, but there was no difference in the $LD_{50}s$ of the wild-type and the malQ mutant in mice. Therefore, it appears that MalQ is less important in the pathogenesis of V. vulnificus than would have been predicted by considering maltose as a most common sugar in the intestine, but not completely dispensable for virulence in mice.

화석연료의 무분별한 사용에 따라 이산화탄소 배출 등 환경오염의 문제가 대두되면서, 전 세계적으로 신 재생에너지 및 친환경 에너지에 많은 연구가 이루어지고 있다. 연료전지는 전기에너지를 발생시키며 부산물로써 물만을 생성하는 친환경 에너지 발전 장치이다. 특히, 음이온 교환막을 이용한 알칼리 연료전지(Anion Exchange Membrane Alkaline Fuel Cell, AEMAFC)는 수소이온 교환막을 이용한 연료전지(Proton Exchange Membrane Fuel Cell, PEMFC)에 비해 보다 높은 촉매의 활성으로 인해 저가의 금속 촉매의 사용이 가능하다는 장점이 있다. 이러한 AEMAFC에서 요구되는 AEM의 특성으로는 연료전지가 작동하는 높은 pH 조건에서 높은 이온전도도 뿐만 아니라 화학적 안정성이다. 본 연구에서는 화학적 안정성을 극대화 시키기 위하여 poly(2,6-dimethyl-1,4-phenylene oxide) 고분자에 spacer-type의 전도기를 도입함과 동시에 가교법을 이용하여 높은 이온전도도($80^{\circ}C$, $67.9mScm^{-1}$)와 기계적 성질(영률 : 0.53 GPa) 뿐만 아니라 높은 pH 조건에서 화학적 안정성($80^{\circ}C$, 1000 h, 6.8% loss of IEC)을 갖는 AEMAFC용 고분자 전해질 막으로써의 가능성을 제시하였다.
