The purpose of this study is to discuss the new ways to help understand the terminology based on the abilities and value of martial art that are reviving current day. Coming out of the limited traditional theory of Japanese Budo, Chinese Wushu, and Korean Muyae's and combining the oriental martial art and universal value, we have to build the an organization that unites the all the theories that can spread world wide. In order to accomplish this, we need to understand and recognize the general ideas of martial art which are the purposes and values that people followed through cultural act called martial art, or the function of cultural field of martial art in the human society. Also, we need the demands of criticism and new paradigm on approach on the field of study. In the direction of flowing the theories of martial art depending on western physical education's science, it causes various of important compressed meaning and problems philosophically and realistically. As shown, there should be mord studies on historical, mental, and cultural no the concepts of Wushu, Muyea and Budo, but comparing such as the superiorities or appropriateness with them by personal opinion should be sublated. Rather then wasting time on terminology of the concepts appropriateness, we should put our efforts on studying something that are productive and developable such as historical contrast cultural study, demand on newly changing world and etc. in order to fill in the empty space of martial art(Wushu, Muyea, Budo)'s identity.

Both pattern of water use and pollutant load were investigated in the apartment area for the middle class of a new town. Especially the analysis of the effect of saving water under public information of saving water was used to search possible quantities of saving water. The results of this survey showed that each household had 3.84 persons with water use rate of 262 L/capitaㆍd on an average. The average domestic loading for COD, BOD, SS, T-N and T-P were 107.5, 49.5, 50.1, 7.7 and 1.6 g/capitaㆍd, respectively. Water used by residential households consists of water for washing clothes, toilets, bath, showers, kitchen, washing up and sweeping. Among above sources toilet water (26%) occupied the largest component of residential water use. Also the reduction of total water use was 12.3% by public information of saving water.

The prognosis of oral malignant melanoma is poor compared with cutaneous melanoma. It may be related to the difficulty of wide enough resection, the early hematogenous matastases, higher stage at initial diagnosis, tendency to growth vertically. In the view of histological differences between oral mucosa and skin, it is impossible use Clark’s and Breslow’s classifications for prognosis. The great problem is that there is still no consensus on the treatment due to rarity. Because data collection from case reports is considered to be the best source of information and should be pooled to anlalyze key determinants of outcome, We reported on 6 cases of primary malignant melanoma of the oral cavity which were diagnosed and treated in Pusan National University Hospital recently and reviewed the literature. Immunohistochemical study on S100 Protein, GP 100 (HMB-45) with biopsy was usable to confirm the melanoma. Neck dissection including wide excision is recommended if lymph node involvement is suspected. Additionally, adjuvant chemotherapy could be supporting therapy.

chitosan은 D-glucosamine이 β-(1→4) 결합으로 중합된 homopolymer로 chitin을 탈아세틸화(deacetylation)하여 제조된다. chitin은 갑각류의 껍질이나 곤충의 외피, 사상균체의 세포벽을 구성하고 있다. chitin, chitosan 또는 그 분해산물이나 유도체들의 산업적 효율성이 밝혀지면서, 이에 대한 연구가 활발히 이루어지고 있다. 그 중의 한 분야가 효소 분해법을 이용한 chitosan oligomer(chitosanoligosaccharides)의 생산이다. 본 연구에서는 chitosan을 분해하는 미동정 세균의 배양액으로부터 chitosan 가수분해효소(chitosanase)를 분리·정제하여, 주요 특성을 조사하였다. 세균의 무세포 배양액을 한외여과기(NMWL, 1K)로 여과하여 저분자량의 화합물을 제거한 다음 황산암모늄을 가하여 90% 포화시키고, 침전된 단백질을 회수하여 gel permeation chromatography(sephadex G-10과 G-100)로 chitosanase를 정제하였다. 정제전 효소의 비활성은 5.8U/mg 이었으나 정제과정을 통하여 9.7U/mg으로 증대되었다. 정제 전후를 통하여 SDS-PAGE 법에 의한 단백질의 분석과 효소활성 염색으로 한 종류의 chitosanase가 확인되었으며, 그 분자량은 약 30,000dalton 이었고, subunit는 한 종류인 것으로 추정되었다. chitosanase에 의한 기질의 분해산물을 한외여과와 TLC로 분석한 결과, 이 효소는 이량체에서 육량체까지의 chitosanoligosaccharides를 생산하였으며, 단량체를 생산하지 않는 특징이 있었다. 효소반응 최적온도는 40℃이었고, 50℃ 이상에서는 효소의 활성이 급격히 저하되어, 비교적 열안전성이 낮았다. 또한, 이 효소는 pH 5.0∼9.0 범위에서 1시간 방치해도 활성변화가 미미하여, 비교적 광범위한 중성영역에서 안정하였다. Chitosan is a polymer of D-glucosamine linked by β-(1→4) covalent bonds. It is obtained through deacetylation of chitin that occurs mainly in the shells of crustaceans and the exoskeletons of insects. It is also found in fungal cell walls. Having relatively rich natural resources, chitin and their derivatives are widely utilized in industries. Among those are chitosanoligosaccharides that are reported to have several biological functions. The production of chitosanoligosaccharides requires hydrolysis of chitosan by an acid or an enzyme. A chitosanase, the chitosan-depolymerizing enzyme, was purified from unidentified bacterial culture and its characteristics were determined. Cell-free culture of the unidentified bacterium was filtered with ultramembrane(NMWL, 1K) to remove low molecular weight compounds. Ammonium sulfate was added to the filtrate at the level of 90% saturation to induce precipitation of proteins. The precipitated proteins were desalted with sephadex G-10 column and fractionated through sephadex G-100 gel permeation chromatography. Specific activity of the enzyme before purification was 5.8 units/mg and was increased up to 9.7 units/mg through purification procedures. SDS-PAGE analysis of proteins and enzyme activity staining revealed only one kind of chitosanase in the bacterial culture. Its molecular weight was about 30,000 dalton with one kind of subunit. The catalytic unit could highly be a monomeric protein. TLC-analysis of enzymatic hydrolysis products of chitosan showed that the enzyme generated dimeric through hexameric oligomers of D-glucosamine without producing monomeric D-glucosamine. Its optimum temperature for catalytic activity was 40℃ and the catalytic activity dropped rapidly at the temperatures higher than 50℃, which reflected its low heat stability. The enzyme was stable for at least one hour at neutral pH ranges from 5.0∼9.0.

This study investigates the effect of compressive strength and longitudinal steel ratio of concrete on the behavior of reinforced concrete columns and conducts the experiment of the behavior of reinforced concrete columns with normal and high strength by giving a slenderness ratio(λ=50) the columns with square section (100×100 mm) to analyze the relations to bending moment, bending displacement and ultimate strength and by having the variables of concrete compression strength (180kgf/㎠, 819kgf/㎠) and longitudinal steel ratio (0.5%, 1%, 4%, 5.7%, 10.3%). As a result, the strain of compressed steel shows considerably increased trend more than tensile steel strain and on the form of fracture in the case of low strength, as the longitudinal steel ratio is increased more, the number of crack in considerably increased and on the form of fracture in the case of high strength, there in little crack in early loading, but when it reaches the ultimate loading, it causes instantaneous breaking. Especially, when column of 0.5% and 1% of longitudinal steel ratio reaches its ultimate loading, it is broken with the phenomena that the both sides of central part are divided, and the cases of 5.7% and 10.3% of longitudinal steel ratio, the ultimate loading value is not greatly increased.

Background : More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patients with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). Methods : A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. Results : Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). Conclusion : The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.
