  • This paper is a research that investigated the distribution and status of coastal sand dunes spread along the shoreline of Ongjin-gun, Jung-gu in Incheon and evaluated their conservation status. In Incheon, the length of coastline along the West Sea shoreline is 1,053km. thus leading to an assumption that coastal sand dunes are dispersed their as many as other regional local government. However, there are no enough basic data on the distribution, characteristics, and the management status of other areas besides the 5 places on the list by the Ministry of Environment. Considering this fact, this paper additionally drew 21 coastal sand dunes in the shoreline of Incheon, including the 5 places on the list by the Ministry of Environment, through the standard of coastal sandhill selection. The additionally selected aimed to propose how to develop basic materials on the conservation status of coastal sandhills in Incheon through characteristic analysis by sandhill and qualitative evaluation.

  • Objective : The mechanism of acupuncture to increase cerebral blood flow is still uncertain. The purpose of this study was to evaluate the neural basis of acupuncture by comparing the cerebral regions activated by the stimulation of two different methods of acupunctures at the same acupoint which was suggested by oriental medicine to increase rCBF. Materials and Methods : Thirty-nine healthy volunteers(26 males, 13 females, age $31{\pm}11$ years) were studies by rest/acupuncture Tc-99m ECD brain SPECT using a subtraction method. SPECTs using two methods(needle retention and heated needle with 90% alcohol) at two acupoints (right LI. 4 and ST. 36) were peformed at an interval of three days. For the needle retention method, acupuncture needle was inserted to a depth of about 2 cm into each acupoint 8 minutes after the lst acquisition and continued to retain, and the second injection of Tc-99m ECD was done 15 minutes after the insertion of needle. For the heated acupuncture method, heated needle was inserted in a twinkle within several msec 20 second after the second injection of Tc-99m ECD. The differences of between rest and acupuncture activation state were statistically analyzed using a statistical parametric mapping software. Result : Acupunctures of both methods reveal similar patterns of increase in rCBF. Acupuncture at ST.36 increase rGBF in left anterior temporal, right inferior frontal lobes, and left cerebellum. Acupuncture at LI. 4 increase rCBF in the left frontal cortex, right temporal pole, both inferior frontal cortices and right cerebellum. Conclusion : The effects of two different acupunctures to the same acupoints on rCBF were similar. Therefore, this result suggests Chat the mechanism of acupuncture in the increase of cerebral blood flow have a neural basis.

  • Tropical forests play a key role for functioning of the planet and maintenance of life. These forests support more than half of the world's species, serve as regulators of global and regional climate, act as carbon sinks and provide valuable ecosystem services. Forest floor biomass and litterfall dynamics was measured in different sites influenced by fire in a seasonally dry tropical forest of Bhoramdeo wildlife sanctuary of Chhattisgarh, India. The forest floor biomass was collected randomly placed quadrats while the litterfall measured by placing stone-block lined denuded quadrat technique. The seasonal mean total forest floor biomass across the fire regimes varied from $2.00-3.65t\;ha^{-1}$. The total litterfall of the study sites varied from $4.75-7.56t\;ha^{-1}\;yr^{-1}$. Annual turnover of litter varied from 70-74% and the turnover time between 1.35-1.43 years. Monthly pattern of forest floor biomass indicated that partially decayed litter, wood litter and total forest floor were differed significantly. The seasonal variation showed that leaf fall differed significantly in winter season only among the fire regimes while the wood litter was found non significant in all the season. This study shows that significant variation among the site due to the forest fire. Decomposition is one of the ecological processes critical to the functioning of forest ecosystems. The decomposing wood serves as a saving account of nutrients and organic materials in the forest floor. Across the site, high fire zone was facing much of the deleterious effects on forest floor biomass and litter production. Control on such type of wildfire and anthropogenic ignition could allow the natural recovery processes to enhance biological diversity. Chronic disturbances do not provide time for ecosystem recovery; it needs to be reduced for ecosystem health and maintaining of the high floral and faunal biodiversity.

  • This study dealing with the Italian futurist and Russian constructivist costume designs which aimed for new fashion design freed from the conventional meanings of fashion and explore the artistic purpose reflected within the designs expressed differently according to cultural and regional differences in order examine the early 20th century Avant-grade costume designs. The scope of this study is limited to the 1910s to the 1930s when the Italian futurism and the Russian constructivism were originated and were most active. This monograph focused on the works of the Italian futurists, Giacomo Balla who declared the 'Manifesto delle moda minile futurista', Fortunato Depero, and Thayaht who suggested a new direction for the futurist, and on the works of the Russian constructivists Alexander Rodchenko, Varvara Stepanova and Liubov Popova. As an one method of investigated, this paper is used materials of various sources to examine their features. Futurists costume designs expressed a radical conception of progress and their source of aesthetics was dynamism. The concept of 'power' which was the basis of the futurists was incorporated in the costumes while non-symmetrical cut-outs and bright and vivid colors completed the futurist costume designs. Moreover the Russian constructivists brought advances in the field of fabric and textile designs. What was particularly interesting about the Russian constructivist costumes was that the artists worked at the textile mills themselves, directly involved in the designs and manufacturing of fabric, developing an advancement in textile and a new understanding of costume. Furthermore, many Russian artists settled in Paris, actively participating in the fashion industry, and therefore, they have greatly contributed to the development of the early 20th century Avant-garde costume designs.

  • The purpose of this study is to examine the characteristics that appeared in the fashion and colors of exotic tastes used by Renoir with a view to re-evaluating his-attitude towards exotic tastes. The methods used in this study were literature research and analysis of visual data from Renoir's works. The results of the study are as follows. Renoir's exotic tastes originated from the material perspective appearing in the fashions and accessories of Algeria, Orient, Spain, and Japan. Parisienne Odalisque Lise in Harem-style, Jeanne Samari in parisienne fashion holding a Japanese fan, and Gabriel in oriental fashion were portrayed as major muses. The Algerian style consisted of white, yellow or red veils, thobes, loose pants worn in Haik, and burnous. The Oriental-style was composed of harem pants, turbans, hair accessories, ornate zouave jackets, and oriental ornaments. The Spanish-style showed gay ornaments, fitted red or yellow matador costume, red bandannas, black hats, and red dresses, plus Spanish guitars. The Japanese-style consisted of kimonos, accessories such as fans, and backgrounds with interior articles such as vases, wall picture frames, and folding screens. The exotic fashion colors were red, yellow and white. Renoir expressed the works with his delicate skills and sense of craftsmanship, and he even added creative design portrayals sometimes. He selected fashions and accessories of exotic tastes as objects and expressed the objects with materials and colors reflecting regional characteristics as such, he can be regarded as an artist wed to who fashions of exotic tastes.

  • Purpose: The purpose of this study was to compare the clinical and radiologic results of arthrodesis between anterior approach and transfibular approach arthrodesis in ankle arthritis. Materials and Methods: There were 61 cases of ankle arthritis treated by anterior or transfibular ankle arthrodesis in our hospital from April 2008 to March 2012. We investigated 29 cases (27 patients) who underwent ankle arthrodesis with an anterior approach (15 cases) and transfibular approach (14 cases), and were followed for over two years. Clinically, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, pain visual analogue scale (VAS), and subjective satisfaction degrees were evaluated. In addition, ankle coronal and sagittal alignments were evaluated using plain radiographs at 6 and 24 months, postoperatively. Results: Clinically, preoperative mean AOFAS score and VAS was 41.3 and 6.4, and were changed to 58.9 and 3.3 postoperatively in the anterior approach group. In the transfibular approach group, preoperative mean AOFAS score was 36.6 and VAS was 7.1, and they were changed to 54.9 and 3.4 postoperatively. However, no significant differences in the clinical results were observed between the two groups (p=0.297). Duration of attaining union was 8.1 weeks in the anterior approach group and 10.4 weeks in the transfibular approach group. Complications were delayed union in one case, nonunion in three cases, cancellous screw breakage in three cases, and complex regional reflex syndrome in one case. Conclusion: After transfibular ankle arthrodesis as treatment of ankle osteoarthritis, the tendency for valgus angulation of the ankle at the final follow-up was observed and 6.5 mm cancellous screw breakage occurred frequently. Therefore, in order to achieve better stability, it is necessary to use 6.5 mm cannulated screws rather than 6.5 mm cancellous screws for ankle arthrodesis.
