  • 근대적 기상관측이 시작된 1905년 이후 우리나라의 연평균 강수량은 증가하고 있으나 강수량 변동폭 또한 커지면서 최갈수 기간의 영향을 받는 댐 등 대규모 수공구조물의 용수공급능력은 감소되고 있다. 또한 지역별 강수량과 인구 편차로 공간적으로 이용 가능한 수자원의 불균형이 발생하고 있어 지역적인 물 공급의 안정성과 형평성은 여전히 취약한 상황이다. 하지만 사회적 공감대 형성이 쉽지 않은 대규모 수자원개발 추진은 어려운 여건이며 국민들의 안전하고 맑은 물에 대한 수요 또한 지속적으로 증대되고 있어 이를 해소하기 위한 다각적인 대책 마련이 필요한 상황이다. 본 연구에서는 기 확보된 수자원의 효율적이고 공평한 활용을 위해 국내 용수공급의 중추적인 역할을 담당하고 있는 댐을 대상으로 댐간 연결을 통한 용수공급 방안을 제시하였다. 이를 위하여 소양강댐, 충주댐 등 다목적댐 16개 및 광동댐, 영천댐 등 용수댐 12개 총 28개댐의 용수공급능력 평가와 장래 용수수요량 조사를 실시하였으며 장래 용수부족 지역 해소를 위한 상시공급과 극한가뭄 등 재난 대처를 위한 비상시공급 방안을 검토하였다. 상시공급은 댐 용수공급능력 평가를 통하여 기본계획공급량 대비 여유수량을 갖는 댐에서 장래 용수수요 증가, 용수공급능력 감소 등으로 공급 용수가 부족한 인근 댐으로 공급하는 방식이며 용수 공급량은 저수지 모의운영을 통하여 양댐의 이수안전도(분석 기간중 1회에 한하여 물 부족 허용)를 충족시키는 수량을 산정하였다. 비상시공급은 타수계 및 근거리간 연결, 가뭄 예상지역을 기준으로 대상 댐을 검토하였으며 용수 공급량은 공급댐의 유지용수와 관개용수를 이용하여 공급받는 댐의 생 공용수 20% 공급가능시 공급량으로 산정하였다. 검토 결과 상시공급은 소양강댐에서 횡성댐으로 86천$m^3$/일, 장흥댐에서 주암본댐으로 127천$m^3$/일, 남강댐에서 수어댐으로 $140m^3$/일, 비상시 공급은 충주댐과 대청댐, 충주댐과 안동댐간 각각 500천$m^3$/일 공급을 통하여 장래 용수부족 지역의 물 부족 해소와 극한가뭄 등 비상상황의 대처가 가능한 것으로 분석되었다. 본 연구는 기후변화와 사회가치적으로 변화하고 있는 수자원 환경에 능동적으로 대처하기 위한 대책의 일환으로 고안된 것이며, 향후 유역간 물 이동에 따른 현행 수리권제도 및 어류, 수질변화에 따른 환경영향 등에 대하여 추가적인 연구가 필요할 것으로 판단된다.

  • This study is aimed at researching Gyobang Dance performed by gisaeng of Gyobang in the banquet of Tonshinsa in Yeongnam Jwa-do Province. For this study, Hae-haeng-chong-che, a collection of 28 travel essays written by Joseon Tonshinsa after visiting Japan, and a collection of literary works were analyzed. Joseon Tonshinsa used Yeongnam Jwa-do Province as a route to Japan in obedience to a royal command, and Yeongnam U-do Province as a way back to Hanyang after completing their missions. The country gave a huge banquet to relieve Tonshinsa's anxiety about the voyage and to pray for a safe trip. The banquets were concentrated in Yeongnam Jwa-do Province, the way down to Busan departing from Hanyang. Looking into Tonshinsa's records, it can be seen that Tonshinsa banquets took place in Andong, Yeongcheon, Gyeongju, Milyang, and Busan. Gyobang Dance performed at Tonshinsa banquets includes Geommu, Hwangchangmu, Cheoyongmu, Cheondo, Mudong, Ipchum, and Jungchum. Through Tonshinsa envoy, 'Jeseon Tonshinsa-gil' was formed in Yeongnam Jwa-do Province, and through Tonshinsa banquets, the artistry of Gyobang Dance was compiled. Nevertheless, present Yeongnam Jwa-do Province has remarkably less Gyobang Dance passed down in comparison to Yeongnam U-do Province. For this reason, there is a need to look into Gyobang Dance of Yeongnam Jwa-do Province. The purpose of this study is to closely examine the cultural and artistic characteristics of Gyobang Dance performed at Tonshinsa banquets in Yeongnam Jwa-do Province formed through Joseon Tonshinsa-gil.

  • White jelly fungus (Tremella fuciformis Berk; TF) has been used as a traditional medicine in Asia; it is known to prevent hypertension, aging, cancer, and arteriosclerosis. This study aimed to investigate the anti-diabetic effects of fermented Tremella fuciformis Berk (FTF) ethanol extracts fermented with L. rhamnosus BHN-LAB 76. We show that FTF increases the ${\alpha}$-glucosidase inhibitory activity and suppress the adipogenesis of 3T3-L1 adipocytes. These inhibitory effects of FTF are accompanied by the regulation of the phosphorylation of AMPK, JNK, and Akt. These data demonstrate that FTF not only inhibits adipogenesis by affecting the adipogenic signaling, but also increases the anti-diabetic effects by regulating the insulin signaling pathway. Therefore, we suggest that the FTF can be used for developing functional food and cosmetics materials.

  • Seochon('West Village') is located in the west side of Gyeongbokgung(Gyeongbok Royal Palace) inside the old city wall of Seoul. Seochon has beautiful scenic view surrounding Mt. Inwang and has been known as the representative historical and cultural landscape region in Korea that historical and cultural resources are rich. But when the figure of Seochon which has repeated the changes with the ones of the times is considered, values of beauty of natural landscape that Seochon had and its own placeness have not been gradually recognized as it has been swept away in logic of the development on the strength of economics. This study tries to examine the original form of landscape on Seochon which can be the standard of landscape change, the causes and process of its change and possibility to conserve and restore it to recognize potential value about historical culture of Seochon landscape and conserve and protect it. For this, this study compared and analyzed literature including poems and Yusangi, paintings and names of the scenery of the seasons as the landscape texts with the current status. The study result has found that Pilwundae should rehabilitate cultural assets to secure the prospect right and protect neighboring bedrock, Suseong-dong should expand the restoration areas focusing on the projects to make parks which are now being restored, Cheonghwigak and Cheongpunggye areas should restore waterways including historicity which is connected to figures and Seshimdae and Baekun-dong green zone should set the protective area for conservation.

  • In order to improve the mechanical reliability of next-generation electronic devices including flexible, wearable devices, a high level of mechanical reliability is required at various flexible joints. Organic adhesive materials such as epoxy for bonding existing polymer substrates inevitably have an increase in the thickness of the joint and involve problems of thermodynamic damage due to repeated deformation and high temperature hardening. Therefore, it is required to develop a low-temperature bonding process to minimize the thickness of the joint and prevent thermal damage for flexible bonding. This study developed flexible laser transmission welding (f-LTW) that allows bonding of flexible substrates with flexibility, robustness, and low thermal damage. Carbon nanotube (CNT) is thin-film coated on a flexible substrate to reduce the thickness of the joint, and a local melt bonding process on the surface of a polymer substrate by heating a CNT dispersion beam laser has been developed. The laser process conditions were constructed to minimize the thermal damage of the substrate and the mechanism of forming a CNT junction with the polymer substrate. In addition, lap shear adhesion test, peel test, and repeated bending experiment were conducted to evaluate the strength and flexibility of the flexible bonding joint.

  • This study was designed to analyze the social and institutional problems that may arise in the early 2000s of the United States and in the scholarship program for university student-athletes by analyzing Dialogues in the Film [The Blind Side] and to derive the meaning of this to Korean society and education field. In summary, the first is that there is a need for fundamental change in the thinking about gender discrimination and racist expressions expressed in everyday life including a Sport field not only in the United states but also in Korean society. Second, the Korea University Sports Federation(KUSF), like NCAA, is working on the right to study and human rights of university athletes, but in the commercialism of modern sports related to the capitalism, these systems and regulations could be a bigger obstacle to the process of growing young players. And finally, like the case of "Flower-loving Ferdinand" who having a lot in common with the main character, Michael in the Film, I hope that there will be a "Sports Ferdinand" that likes the sport itself, which is fully satisfied with its life and lives happily even if it is not a sports star.

  • The purpose of this study is to analyze the narrative structure and types of films that has attracted more than 10 million viewers ('10 million films') among films released in Korea, and deal with the implications of the current Korean film industry. To this end, this study investigated the relationship between films and their narrative as a product of the film industry. To approach this, We dealt with the features of structuralist analysis and archetype or mythological narrative analysis. For a detailed analysis, a total of 27 films of "10 million films" were categorized using Northrop Frye's original narrative analysis method. As a result of the study, 13 comedy structures, 7 romance structures, 4 tragic structures, and 3 irony and satire structures. It was confirmed that the "comedy" and "romance" structures had a high percentage of all 10 million films, and occupied the top ranks in the box office rankings. In conclusion, this study confirmed the narrative rules and customs of films hitting Korean box offices, and through this, it was possible to examine a rough topography of the film consumption of the public in the Korean film industry. This can be said to provide a clue as to how the narrative of the film should be constructed when producing a film from an industrial perspective.

  • At present, many countries around the world are legalizing cannabis and its products, and research on various treatments using cannabis is being actively conducted. However, the cannabis plant contains other compounds whose biological effects have not yet been established. We investigated the effect of cannabidiol (CBD) on hair growth in human dermal papilla cells (HDPCs). 2,2'-Azino-bis (3-ethylbenzothiazolin-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays were performed to determine the antioxidant activity of CBD. The HDPCs viability of CBD was examined via water-soluble tetrazolium salt (WST-1) assay. The expression of hair-loss-related markers in HDPCs by CBD treatment was analyzed by real-time PCR and western blotting. The DPPH, ABTS radical scavenging activity assay showed that CBD had superior antioxidant activities. In HDPCs, CBD increased cellular proliferation at concentrations without cytotoxicity. It also increased the expressions of fibroblast growth factor 1 (FGF1), fibroblast growth factor 7 (FGF7), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF). These results correlated with a decrease in the expression of inhibition-related factors, such as androgen receptor (AR) and transforming growth factor beta 1 (TGF-B1). Moreover, CBD resulted in a significant increase in the phosphorylation of AKT and extracellular signal-regulated kinase (ERK). Therefore, it is suggested that CBD may be a potential remedy for the treatment of alopecia.

  • The results of study on the meaning landscape and environmental design techniques of the Byulup, Yoohoedang garden(Hageowon) based on the story in the collection of Kwon Yi-jin (Yoohoedangjip, 有懷堂集), are as below. First, Yoohoedang Kwon Yi-jin (有懷堂 權以鎭 : 1668~1734) constructed a Byulup garden consisting of ancestor grave, Byulup, garden, and a school, through 3 steps for 20 years in the back hill area of Moosoo-dong village, south of Mountain Bomun in Daejeon. In other words, he built the Byulup(別業, Yoohoedang) by placing his father's grave in the back hill of the village, and then constructed Yoegeongam(餘慶菴) and Geoupjae(居業齋) for protection of the pond(Napoji, 納汚池), garden(Banhwanwon, 盤桓園), and ancestor graves, and descendants' studying in the middle stage. He built an extension in Yoohoedang and finally completed the large-size garden (Hageowon) by extending the east area. Second, in terms of geomancy sense, Yoohoedang Byulup located in Moosoo-dong village area is the representative example including all space elements such as main living house (the head family house of Andong Kwon family), Byulup (Yoohoedang), ancestor graves, Hagoewon (garden) and Yoegeongam (cemetery management and school) which byulup type Byulseo should be equipped with. Thirdly, there are various meaning landscape elements combining the value system of Confucianism, Buddhism and Taoism value, including; (1) remembering parents, (2) harmonious family, (3) integrity, (4) virtue, (5) noble personality, (6) good luck, (7) hermit life, (8) family prosperity and learning development, (9) grace from ancestors, (10) fairyland, (11) guarding ancestor graves, and (12) living ever-young. Fourth, after he arranged ancestor graveyard in the back of the village, he used surrounding natural landscapes to construct Hagoewon garden with water garden consisting of 4 mountain streams and 3 ponds for 13 years, and finally completed a beautiful fairyland with 5 platforms, 3 bamboo forests, as well as the Seokgasan(石假山, artificial hill). Fifth, he adopted landscape plantation (28 kinds; pine, maple, royal azalea, azalea, persimmon tree, bamboo, willow, pomegranate tree, rose, chinensis, chaenomeles speciosa, Japanese azalea, peach tree, lotus, chrysanthemum, peony, and Paeonia suffruticosa, etc.) to apply romance from poetic affection, symbol and ideal from personification, as well as plantation plan considering seasonal landscapes. Landscape rocks were used by intact use of natural rocks, connecting with water elements, garden ornament method using Seokyeonji and flower steps, and mountain Seokga method showing the essence of landscape meanings. In addition, waterscape are characterized by active use of water considering natural streams and physio-graphic condition (eastern valley), ecological corridor role that rhythmically connects each space of the garden and waterways following routes, landscape meaning introduction connecting 'gaining knowledge by the study of things' values including Hwalsoodam(活水潭, pond), Mongjeong(蒙井, spring), Hosoo(濠水, stream), and Boksoo(?水, stream), and sensuous experience space construction with auditory and visualization using properties of landscape matters.

  • Yams (Dioscorea spp.) have been used as medicinal and edible resources worldwide. In the present study, methanol extracts were prepared from various kinds of yam, including D. batatas (Gyeongbuk No. 1 and No. 4), D. alata L. (Gyeongbuk No. 5 and No. 6), and D. bulbifera and D. nipponica, and the antioxidant, antithrombin, and antimicrobial activities of these extracts were evaluated. The water content of the various yams was 54.7~83.2% (D. batatas> D. alata L.>D. nipponica>D. bulbifera) and the methanol extracts contained 0.59-1.59% (w/v) solid matter (D. alata L.>D. batatas >D. nipponica>D. bulbifera). The mean concentrations of total polyphenols, total flavonoids, and total sugars in the different types of yam were 49.82 mg/g, 9.79 mg/g, and 173.81 mg/g, respectively. Analysis of DPPH radical-scavenging activity showed that D. alata L. Gyeongbuk No. 6 had a strong antioxidant capacity (IC50=$142.30{\mu}g/mL$), whereas the other yams showed reduced levels of activity (IC50=371-$486{\mu}g/mL$). D. alata L. Gyeongbuk No. 6 showed a strong antithrombin activity against human thrombin. Upon treatment with a D. alata methanol extract (1.5 mg/mL), thrombin time was increased 7.35-fold compared with that when methanol alone was used. In an antimicrobial activity assay, the D. nipponica extract showed moderate antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Proteus vulgaris, and Salmonella typhimurium. Our results indicate that different varieties of Dioscorea spp., including D. batatas, have useful biochemical attributes, including antioxidant, antithrombin, and antibacterial activities.
