  • 80 년대 이후 국내 뮤지엄은 양적으로 많은 성장을 이루었고, 현재 전국에는 200 여 개의 뮤지엄이 개관 중이다. 이 중 많은 뮤지엄들이 기존의 역사나 자연사를 주제로 한 뮤지엄과는 다른, 다양한 주제와 내용을 다루는 '테마 뮤지엄' 을 표방하고 있지만 여러 면에서 외국의 선진 테마 뮤지엄에 비해 열악한 것이 사실이다. 이에 본 연구에서는 완성도 있는 테마뮤지엄을 위해서 테마뮤지엄의 구조를 내러티브 특성에 따른 고찰을 통해 구조적으로 이해하고자 하였다. 이에 본 연구에서는 테마뮤지엄의 속성을 규명한 후, 완성도 있는 테마뮤지엄의 실현을 위해서는 뮤지엄 내 내러티브성의 확립이 필수적이라는 가설을 검증하고자 하였다. 또한 이를 통해 테마뮤지엄의 기본 속성이 내러티브 구조에 있음을 논증하고 이러한 내러티브 구조가 명확히 드러나는 테마뮤지엄을 실현하기 위한 디자인 방법론적 접근으로써 테마뮤지엄의 내러티브구조 확립을 위한 방법틀을 제안하였다. 이 방법틀은 테마뮤지엄의 내러티브 구조, 내러티브 유형별 포지셔닝맵, 내러티브 체험과 재방문력 창출의 상관 정도를 제공함으로써 테마뮤지엄 디자이너의 내러티브 구조에 따른 디자인 개선책 도출을 도울 수 있을 것으로 사료된다. 또한 제안한 방법틀의 디자이너와 사용자 간 수용도를 알아보기 위해 사례연구를 실시하였는데, 그 대상으로 국내 뮤지엄 가운데 8 곳을 선정하였다. 이를 통해 내러티브 구조에 따른 디자인 계획이 관람객의 만족도에 큰 영향을 미침을 입증할 수 있었다. 이상의 연구는 국내 중소규모 테마뮤지엄의 질적 성장에 기여할 것이며, '테마'라는 특성을 가진 환경에 확대하여 적용할 수 있을 것으로 사료된다.

  • Background: A ureteropelvic junction (UPJ) obstruction is a congenital anomaly commonly afflicting the pediatric population. However, it occurs more frequently in adults than is generally appreciated. To assess their characteristics, we have here compared and analyzed the clinical manifestations, causes, and outcomes of UPJ obstruction found in children and adults. Materials and Methods: 102 patients (118 renal units) out of 182 patients (218 renal units), with diagnosed UPJ obstruction, were available for follow up. The follow-ups were retrospectively reviewed to determine the presenting symptoms, treatments, and clinical outcomes. Patients who were younger than 18 years of age were assigned to the pediatric group (44 patients), others the adult group (58 patents). Results: The majority of the patients presented with flank pain (pediatric group: 68%, adult group: 76%). The majority of patients underwent a pyeloplasty (pediatric group: 50.9%, adult group: 62.3%). And the major cause of the UPJ obstruction was an intrinsic stenosis (pediatric group: 53%, adult group: 56%). Conclusion: The prevalence of bilateral UPJ obstruction in adults is evidently less prevalent than in pediatrics, and despite the late diagnosis, the surgical outcome is similar. A further investigation of UPJ obstruction will lead us to a more comprehensive understanding of the disease.

  • Trees enhance slope stability against down slope mass movement through the removal of soil water by transpiration and by the mechanical reinforcement of their roots. To assess the magnitude of this reinforcement on natural slope stability, direct shear tests were made on dry sand reinforced with different array types of roots. Pinus koraiensis was used as root specimens. The peak shear resistance at each normal stress level was measured on the rooted and unrooted soil specimens. Increased soil resistance(${\Delta}S$) by roots was calculated using parameters like internal friction angle and cohesion of tested soil and also evaluated the effects of root array in tested soil. As results, we find that shear resistance increased in tested soil shear box as diameters and arrayed numbers of root specimen increased and cross root array in tested soil had a much greater reinforcing effect than other root arrays. Comparison of traditional root-soil model with experiments showed that simulated reinforce strength by the model was different with those obtained by the experiment due to its linearity.

  • For teaching-learning to geological region of earth science part in science education, middle school, the practical uses of natural science museum are very effective. So, the appropriate uses of the natural science museum are necessary for the teaching and learning of Science Education. This study aims to consider the presentation characteristics of the natural science museum and to examine how is effective it to geological region in middle school science curricula on those uses. From the results, the natural science museum is low in multi-sided and open-endedness presentation characteristics but high in ones of accessible characteristic. And its presentations are good in multimodal characteristics using supported materials but relatively low in relevant and multimedia ones. In the museum, diorama and self-performing presentation types are not but internet ones are most. The presentations of the natural science museum are mainly assigned to knowledge region linked to basic science concepts but relatively insufficient in STS aspects, on the basis of connection the presentations with middle school science curricula. It is respected that these insufficiencies might be diminished by variable arrangements of and explanations to the presentations for understanding improvements. And, applies to the presentations in STS may be encountered, if multi-sided observations to them is available.

  • This study was performed to analyze test results on drying shrinkage for concrete specimens mixed with various constituents in concrete mixes. Test variables are coarse aggregate types(Limestone, Sandstone, Granite, Andesite, Gneiss), fine aggregate types(natural sand, crushed sand) and cement amounts(normal strength, high strength). Epoxy coating of(U&V-H(A,B)) was applied onto the specimen surface to simulate diverse volume surface ratios(22.2, 40, 85.7, 150, 200, 300) with different specimen sizes. The experiments had been executed during 1,014 days at a condition of $20^{\circ}C$ and relative humidity of 60% in environmental chambers. Test results showed that shrinkage strain from the specimen equivalent to real pavement decreased to 39% compared to the standard specimen recommended by KS. Test results also showed that shrinkage strain of the specimen mixed with Limestone was 56~76% of that with Sandstone, thus Limestone mix seems to be suitable to the concrete pavement.

  • The root of Vitis labrusca, is used as a source of health promoting drug in Korean traditional medicine. It has been reported that root of Vitis labrusca has antioxidant, anti lipid peroxidation and anti-reactive nitrogen species (RNS) activities. The aim of this study was to elucidate the molecular changes of apoptotic signaling pathways in phorbol 12-myristate 13 acetate (PMA)-induced human hepatocellular carcinoma cell line (Hep G2). The root of Vitis labrusca, ethanol extract (RVLEE) was tested for cell viability on Hep G2 cell using the MTT assay. RVLEE exhibited weak cytotoxic activity. However, treatment of Hep G2 cells with RVLEE suppressed PMA-induced cell proliferation. Also, dramatic changes of cell death signals in cellular molecules such as Chk2/Cds1, CIDE-B, CLIMP-63, Bax, Bcl-xL, C-myc, Bcl-2, Bric-5, NIP-3, TRAF2 and BAR but not CIDE-B and DR4. Futhermore, our results showed that the treatment of Hep G2 cells with 25 and $50\; {\mu}g/ml$ of RVLEE suppressed PMA-induced COX-2 gene activity. These data suggest that RVLEE have inhibitory effect of cell proliferation, induction of apoptosis and, thus, may offer therapeutic potential in Hep G2.

  • Taxidermied specimen is the art of preparing, stuffing, and mounting the skins of animals (all vertebrate species of animals including mammals, birds, reptiles, and fishes) for display or for other sources of study. But, as these studies are weighted toward ecologic study, related studies on management and conservation environment are short. Also, the analysis of poisonous gas has not yet been studied. Therefore, this study will be suggested proper preservation methods through the analysis of deterioration on taxidermied specimen by poisonous gas. As a result, 4 types of major chemicals were detected in UV deterioration test, 7 types in RH and formaldehyde deterioration test. As a result of SPME, Naphthalene to be used as antiseptic were detected in all of the test conditions. Acetic acid that is VOCs were detected for factor. Moreover as the higher humidity it was, the concentration of chemicals were decreased.

  • Objectives : The pathophysiology of acute spinal cord injury(SCI) may be divided into primary and secondary mechanisms of injury. The secondary mechanism involves free radical formation, excitotoxicity, inflammation and apoptotic cell death, and sets in minutes after injury and lasts for weeks or months. During this phase the spinal tissue damages are aggravated. Therefore, secondary mechanisms of injury serve as a target for the development of neuroprotective drug against SCI. The present study investigated the effect of tetramethylpyrazine(TMP), an active ingredient purified from the rhizome of Ligusticum wallichii(川芎, chuanxiong), on neuronal apoptosis in spinal cord compression injury in rats. Methods : SCI was subjected to rats by a static compression method(35 g weight, 5 mins) and TMP was treated 3 times(30 mg/kg, i.p.) during 48 hours after the SCI. Results : TMP ameliorated the tissue damage in peri-lesion of SCI and reduced TUNEL-labeled cells both in gray matter and in white matter significantly. TMP also attenuated Bax-expressed motor neurons in the ventral horn and preserved Bcl-2-expressed motor neurons. Conclusions : These results indicate that TMP plays a protective role in apoptotic cell death of neurons and oligodendrocytes in spinal cord injury. Moreover, it is suggested that TMP and TMP-containing chuanxiong may potentially delay or protect the secondary spinal injury.

  • This research validates the correlation between usability and functional attributes whilst comparing the degree of satisfaction of information framework used in museum mobile apps via usability evaluation in pre-visit setting. In cases of Bilbao Guggenheim and American Natural History Museum apps, the degree of satisfaction measured for information service, functional attributes, motivation for actual museum visit and during-visit usability of the apps were all highly evaluated. Such evaluation data indicates the increased usability of apps when mobile applications take user-friendly design that intuitively reflect users' interests and needs. After thorough analysis of correlation between usability and fictional attributes, data pointed to more meaning relationships existed in non-intrusiveness and personalization than other functional attributes. In conclusion, we were able to acknowledge the usability of museum mobile apps depends upon the interaction between content and functional attributes rather than entertainment factor and technology.

  • The purposes of natural science museums are to educate the general public on the principles and application of science, and help them understand various aspects of science technology. Data should be analyzed by considering these educational aspects of exhibition, and the methods of presenting exhibits should be decided. Accordingly, the composition of exhibition contents with various exhibition elements has an important role at natural science museums. The relation and structure of exhibition themes are significant factors in helping visitors understand the principles of science and a system of viewing circulation can be used as an important tool for understanding the flow of exhibition. In other words, at the planning stage for the composition of exhibition contents, the relation of exhibition themes as well as the circulation patterns of viewers can induce active viewing behaviors. Therefore, centering on the patterns of viewing circulation as well as on the connectivity of exhibition themes at natural science museums, the purposes of this research are: 1) to conceptualize the composition of exhibition contents; and 2) to find elements that can induce active viewing behaviors by analyzing visitors' viewing behaviors. This research was establishing an analytical indicator of contact for viewing behaviors observed from the composition of exhibition scenarios, the active viewing patterns of engagement, first contact, and repeated contact were analyzed. First, a composition pattern with a high participation rate, in contact with exhibits, was found to induce an overall-viewing circulation and have a big ring of the composition of exhibition themes. Second, by inducing a partial-viewing circulation pattern, a high rate of first contacts was observed from a ring pattern of theme connection. Even for the structure with theme connection with depth, a high frequency of contacts with various exhibits was found when exhibition themes have a ring pattern. Third, the repeated contacts were mostly found in the form of scenarios, which has a successive structure of ring and cross patterns.
