The value of a structural system is dependent on the performance and the cost. To increase the value of a structural system, we should increase the performance and decrease the cost at the same time. When selecting an adequate alternative among various candidates, we should consider criteria both in performance and cost. In this paper, we propose an Analytic Hierarchy Process based methodology for selecting the optimal bridge alternative among various candidate bridges, which consider multiple evaluation criteria simultaneously. The proposed selection methodology can give the optimal alternative by using not only general qualitative criteria such as sociality, shape and constructibility, but also quantitative criteria such as life cycle cost, structural stability, usability, and environment. However, the proposed methodology is difficult to use manually since it requires much information and complex analysis models. To overcome the lack of practical usability, we also propose a framework for a decision support system which can help the decision maker by using information technology. We expect that the proposed selection method and the decision support system framework can be used as a useful tool for initial planning of structural systems, especially bridges.

Osteochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and the proximal metaphysis of the tibia, however, is occurred rarely in the facial skeleton. Development of the tumor is most frequently seen in the second or third decades of life. Typically, it arises directly from the cortex of the underlying bone, without any intervening zone of abnormal osseous tissue, and is covered by a cap composed of cartilage undergoing calcification. In case of osteochondroma of the mandibular condyle, its clinical features are occulusal change, facial asymmetry, headache, pain and click on temporomandibular joint, mouth opening limitation, and jaw deviation to involved site. This is a case report of a 13-year old woman who had mouth opening limitation and severe temporomandibular joint pain. We obtained successful results with surgical removal of the osteochondroma on the mandibular condyle.

고등어 fillet 제품의 저장 중 항산화의 기능성을 부여하고 고등어 특유의 비린내를 제거하기 위해 식염 외에 녹차, dillweed, 키토산, 올리고당, 생강을 첨가하여 진공포장한 후 5℃, 0℃, -20℃에 80일간 저장하면서 제품 특성을 조사하였다. 5℃에 저장한 고등어 fillet의 휘발성 염기질소 측정 결과는 이들 첨가물을 단독 또는 복합적으로 첨가한 시제품에서 2주 이내에 초기부패에 도달했고, 0℃에서는 4∼7주, -20℃에서는 저장 80일간 모든 시제품에서 신선도를 유지할 수 있었다. 이들 첨가물 가운데서도 키토산과 올리고당을 첨가한 시제품이 가장 신선도가 양호함을 알 수 있었다. 항산화성은 초기 과산화물가가 5.4∼7.8 meq/kg 이었던 것이 5℃ 저장시 35일째 15.7∼20.4 meq.kg, 0℃저장시 49일째 13.9∼18.4 meq/kg, -20℃저장시 80일째 11.6∼20.2 meq/kg으로 저온 일수록 산화속도가 늦었고 각각의 저장온도에서도 녹차, dillweed, 생강, 키토산, 올리고당을 첨가한 시제품에서 가장 산화속도가 늦었다. 친유성 갈색도는 -20℃에서 80일간 저장기간동안 거의 변화가 보이지 않았고 5℃와 0℃에서는 저장기간이 연장됨에 따라 갈색도는 증가하는 경향을 나타내었다. 저장 중 생균수 변화는 5℃와 0℃에서는 저장 80일째까지 생균수 변화는 보이지 않아 신선도 유지가 가능하였다. 관능검사 결과는 5℃저장시 14∼21일, 0℃저장시 28∼49일 점질물이나 산패취가 발생하여 상품적 가치를 상실하였고, -20℃에서는 80일간 저장기간 동안에 이들 변화는 나타나지 않았다. In oredr to endow mackerel fillet with antioxidant effect, functionality and remove fishy smell, chitosan, oligosaccaide, extracts of green tea, dill weed and ginger was used as soaking solution additives. Quality characteristics of soaked mackerel fillet(SMF) was investigated during storage temperature and time after vacuum packing with polyvinyl chloride film. From the results of VBN measurement, initial spoilage was showed within 2 or 3 weeks in SMF soaked with brine including extracts of green tea, herb and ginger at 5℃. In case of adding chitosan and oligosaccarides to the solution mentioned above, initial spoilage was found from 4 to 7 weeks, oxidation was reduced remarkably and SMF stored at -20℃ maintained the freshness during 80 days. Viable cell counts were reached to 108 for 3 weeks storage at 5 and 0℃. But no change of viable cell counts was founded at -20℃. The shelf-lifes of SMF according to 5, 0 and -20℃ storage temperatures were 2 to 3, 4 to 7 weeks and about 3 months, respectively.

Background: Retrograde cardioplegia catheter (RCC) insertion is one of methods for administration of cardioplegics during cardiopulmonary bypass (CPB). However its success rate depends on only surgeon's experience. We thought the transesophageal echocardiography (TEE) can guide the R CC insertion, because TEE is commonly used for monitoring status of heart during cardiac surgery. This study was designed to evaluate the RC C insertion time by TEE guidance versus conventional method without T EE guidance. Methods: Sixty patients who were scheduled to undergo elective coronary artery bypass graft (CABG) surgery under general anesthesia were divided into groups as follows: group T [RCC insertion into coronary sinus (CS) by TEE guidance, n=30] and group C [RCC insertion into CS by conventional method, n=30]. We recorded the time of insertion of RCC in to CS in two groups. RCC insertion was done by TEE guidance in case that time was over two minutes by conventional methods in group C. Results: The overall time of RCC insertion into CS was 63.8 ± 23.6 seconds in the Group T and 102.3 ±55.7 seconds in the Group C, respectively (p=0.001). There were no complications during RCC into CS by T EE guidance. Conclusions: TEE guidance for RCC insertion into CS is shorten the time of insertion.

The natural dye substances appear to have a lot of benefits that enable the dyed materials to exhibit their natural colors. It may have a bit of a harmful influence on the human body itself, in comparison with the synthetic substances. It also causes hardly any environmental pollution because of the natural chemicals and costs much less to disposal. In this study was investigated physicochemical characterization of polygoum tinctoria dye substance and synthetic indigo. Calcium hydroxide was added into polygoum tinctoria leaves to precipitate dye substances and it was freezing dried into powder form. Characterizations of dye substances were investigated by UV/VIS spectrophotometer, TLC, DSC, TGA, HPLC, and MALDI-TOF Mass. Resultantly, polygoum tinctoria was confirmed that is consisted of two ingredients from these results.

This paper describes the application of Yin-Yang & Five Element Theory for the prevention and diagnosis of diseases due to environmental pollution by the scientific interpretation of the basic properties of five elements. The five elements considered are Mok(木,wood), Hwa(火,fire), To(土,soil), Geum(金,metal), SU(水,water). The basic properties of these are explained as warm energy, explosively dispersive heat, agglomerating force, tension or crystallization force, and finally cool & soft energy respectively. Utilizing these basic properties, the constitution classification can be modeled by the shape of face, which is attributed by the relative strength of the major organs, that is, five elements. Further, the vulnerable disease according to the constitution are briefly described together with the therapy method by diet, especially emphasizing the taste of food.

There has been a limited number of data for the long-term concentrations of heavy metals within airborne particulates in Korea. Especially, there exist no such data sets for ambient particulates at the roadside that they should have been produced by using INAA. Therefore, this study focuses on the quantitive analysis of about 30 trace metals including toxic ones for roadside airborne particulates. The study also concentrates on the interpretation of analyzed results for the ambient particulates. From the results of the quantitative analysis for airborne particulates at the roadside by INAA, it is shown that the concentrations of metals such as Al, Ca, Cl, Fe, K, Mg and Na due to crust and marine aerosols are much higher than those of other metals. The concentrations of human carcinogen, arsenic and chromium are 6.71±0.85 ng/m3 and 5.95±0.41 ng/m3, respectively while that of non-carcinogenic toxic metal Mn is 34.08±3.62 ng/m3. During yellow sandy season the concentrations of metals such as Al, Na, Mg, Ca, Fe and K show up to twelve times higher than those in summer. INAA has very low detection limits and needs very small amount of airborne particulate sample for the analysis. However, it is difficult to analyze metals such as Pb, Ni, Cd, and Si, which are very important ones for either risk assessment or receptor modeling. Thus, it is necessary to use other analytical tool like ICP-MS as a complement.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

Grid computing is an emerging technology that promise to unify resources and computing power in many organizations together. It couples a wide variety of geographically distributed computational resources, and presents them as a unified integrated high-end computer. The Globus Resource Allocation and Management(GRAM) service provides for the management and remote execution of jobs defined using a standard Resource Specification Language(RSL) requested by client in grid environment. However, Currently the GRAM has very limited functionality to support for applications that required special execution environment. Here, we provide a proposal for Execution Environment Information interacted with broker to support the GRAM's special execution environment.
