  • 최근 홍수기 유량측정방법은 기존 봉부자를 이용한 접촉식 측정방법에서 영상촬영, 레이더 등 첨단기술을 이용한 비접촉식 표면유속 측정방법으로 변화하고 있다. 비접촉식 측정방법은 각 기술마다 표면유속 측정방법의 차이가 있으나 평균유속환산계수를 적용하여 평균유속을 산정하는 공통적인 과정을 수행한다. 평균유속환산계수는 하천의 각 횡측선 수심-유속분포를 일반적인 분포로 가정하고 표면유속에 0.85를 곱하여 평균유속을 산정한다(Rantz, 1982). 그러나 하천의 측정위치 및 흐름특성에 따라 유속분포가 변화하기 때문에 국내외 많은 연구에서 환산계수의 범위를 0.72에서 1.72까지 제시한 바 있다. 따라서 환산계수 0.85의 일률적인 적용은 실제 유량과 측정 유량의 차이가 발생할 수 있어 측정조건의 적절한 환산계수 산정이 필요하다. 본 연구에서는 20년, 21년 금강의 지류인 봉황천에 위치한 금산군(황풍교) 관측소에서 전자파표면유속계를 이용해 측정한 표면유속과 ADCP를 이용하여 동시 측정한 평균유속의 비교를 통해 환산계수를 산정하였다. 또한 금강 본류의 금산군(제원대교) 관측소에서 저중수위에서 ADCP를 이용하여 측정한 평균유속 분포와 고수위에서 전자파표면유속계로 측정한 표면유속과의 경향성 검토를 통해 평균유속환산계수를 산정하였다. 본 연구에서는 지점의 평균유속환산계수를 단일 값으로 산정하였지만, 추후 하천 흐름특성의 변화를 고려한 평균유속환산계수 산정 기법 개발을 통해 보다 정확한 홍수량을 산정할 수 있을 것으로 판단된다.

  • By studying the classic poetry and prose with a theme of Plantain, I would like to study why Plantain has been planted in our traditional garden for a long time. Also, through this study, I want to find when Plantain was introduced to in our country. We use description study method for studying the classic poetry and prose with a theme of Plantain. As a result, we found a few things like below. First, the introduction of Plantain to our country traces back to unified Silla in the poetry of Choe Chi Won. Also, Plantain was planted and loved generally as a general garden plant in the middle of Goryeo through poetry and paintings. Second, the meaning of Plantain is like this. 1) It means development and enjoyment of arts of summer because the leaves of Plantain were used for drinking alcohol and writing and poetry instead of papers. 2) In Buddhism, Plantain was thought to awaken 'gong(空)', 'mua(無我)', and 'brevity' of lesson of Buddha by the special shape and the image of falling rain to the leaves. Also, it was used widely in Buddhist temples because of the story of 'Hye ga dan bi(慧可斷臂)'. 3) In Confucianism, it is the emblem of lesson 'a wise man tries to be strong and tries not to stop following to God'(自强不息). 4) The large leaf of Plantain is called 'bongmi(鳳尾)' thanks to the image of likeness with tails of Bongwhang(鳳凰). Third, design use of Plantain is like this. 1) The large leaf of Plantain was used for giving an image of freshness and brightness in the garden in summer. 2) Our ancestor thought 'the sound of falling rain to Plantain'(芭蕉雨聲) as a picturesque sound in summer. Also, Plantain was highly utilized because our ancestor thought Plantain is the best plant for implementing 'soundscape'. Thus, the most characteristic use of several design uses is 'acoustic use'. 3) Plantain was also planted in a indoor pot for viewing. 4) Plantain was used for making food and medicine in the palace and private house as a practical use. The limit of this study is that I mainly use the text translated into Korean of database of overall Korean classics. We hope the new things related to this study would be added up to this study by translating original texts into Korean more.

  • This study was conducted to investigate the effect of ecological factors affecting Pinus densiflora forest distribution associated with climate change in the future. Ecological niche is used as a method to quantify the position occupied in biological communities, space, influence and all ecological factors. Ecological niche breadth was analyzed on meteorological and growth factors of P. densiflora. Nine sites (i.e., Gangneung, Jeongseon, Pyeongchang, Hamyang, Bonghwa, Yeongyang, Uljin, Uiseong and Boseong) were selected to set $20m{\times}20m$ quadrat from September to October 2010. The height, DBH, clearlength, crown width and basal area were measured at each quadrat and used as growth factors. In addition, the measured values from the closest weather stations of each survey area of the maximum, mean and minimum temperature, humidity and precipitation were used as meteorological factors. The ecological niche breadth of the five meteorological factors except humidity was low. It is considered that precipitation could effect on the distribution of P. densiflora forest. In particular, maximum temperature showed low ecological niche breadth less than 0.4 in most of the survey areas. However, the ecological niche breadth of the five growth factors was high in all survey areas.

  • In the 7th century, Prince Shoudoku built the Horyu temple at Nara, when Buddhist culture in Japan had highly prospered after Buddhism were transmitted to Japan from Korea. At the same time, the three ancient country of Silla, Koguryo, and Baekjae had generally effected on Japanese culture and life as well as Buddhist events, religious services and sacrificial offerings in form. And even now there are kept above one thousand of tablewares which was used at the age and was made of wood and alloy manufactures from Han peninsular in Seisoin at Nara. Through these historical backgrounds, it could be presumed that the religious services and the sacrificial offerings for Prince Shodoku for above 1300 years help us to study and estimate the ancient dietary culture of Korean and Japanese. There are several points of similarities which are remained and maintained in Han Peninsular. 1. They used high filling method of the secrificial offerings and high receptacles in the religious service. 2. The cakes were mainly made of nonglutinous rice tharr glutinous rice 3. They decorated the pheonix instead of flowers and the other kinds of birds in Korea. 4. Kakiage of fried confectionary was founded in many kinds of them at present.

  • The objective of this study is to identify the reason behind the expansion of exhaust holes and inhalational holes through high-definition filming and measurement of The Gilt-bronze Incense Burner of Baekje. In the proposed experiment, based on the original data obtained after a precise three-dimensional (3D) scan of the said incense burner, the precision replica and the commercial replica of the incense burner were subjected to a 3D scan. The overall shape and detailed patterns were subsequently compared with the original data. Furthermore, the incense-burning experiment was conducted according to the sizes and opened or unopened states of the exhaust and inhalational holes by employing the precision replica of the actual real relic for examining the internal structure of the lid and for studying the sizes and locations of the smoke holes. The results indicate that depending on the sizes of the exhaust and inhalational holes, the lower-line air intake holes can cause incomplete combustion in the incense burner. Depending on the opened or unopened states of the exhaust and inhalational holes, the phoenix air exhaust holes and upper-line air exhaust holes play a primary role in releasing the smoke, whereas the lower-line air intake holes play a primary role in smoke inhalation.

  • This study compared the influence of water quality according to the data sources of spatial information. Firstly, land cover map was constructed through image classification of Daecheong-dam basin and the accuracy of image classification from satellite image showed high as 88.76% in comparison with the large-scaled land cover map in Ministry of Environment, to calculate Event Mean Concentration (EMC) by land cover that impact on the evaluation of nonpoint source pollutant loads. Also curve number and direct runoff were calculated by spatial overlay with soil map and land cover map from image classification. And Seokcheon and Daecheong-Dam basin showed high in the analysis of curve number and direct runoff. Samgacheon-Joint and Sokcheon-Downstream basin showed high in the nonpoint source pollutant loads of BOD from direct runoff and EMC. And Samgacheon-Joint and Bonghwangcheon- Downstream basin showed high in the nonpoint source pollutant loads of TN and TP. Nonpoint source pollutant loads from image classification were compared with those by the land cover map from Ministry of Environment to present the effectivity of nonpoint source pollutant loads from satellite image. And Daecheong-Dam Upstream basin showed high as 10.64%, 11.70% and 20.00% respectively in the errors of nonpoint source pollutant loads of BOD, TN, and TP. Therefore, it is desirable that spatial information including with paddy and dry field is applied to the evaluation of nonpoint source pollutant loads in order to simulate water quality of basin effectively.

  • Feeding habits of Liobagrus andersoni were investigated in a tributary of the Namhan river from October 2005 to October 2006. L. andersoni was considered as an entirely bottom-feeding carnivore based on it's stomach contents. Because, the diet of L. andersoni was mainly aquatic insect such as Ephemeroptera, Trichoptera, Diptera. The most important prey was Ephemeroptera species. Small sized individuals (<50 mm SL) fed mainly on small prey organisms such as Baetis. However, larger Ephemeroptera and Trichoptera were heavily selected with increasing fish size. The relative proportion of food items was changed with season. The prey materials were more various at summer and autumn than winter. L. andersoni eaten Ephemeroptera intensively in spring and summer but eaten Trichoptera and Chironomidae in winter. Feeding activity of L. andersoni was started after sunset and was most active at midnight, but the activity was reduced after sunrise and during day period. So it was considered that L. andersoni was a nocturnal stalkers.

  • This study investigated the problem of the existing rural development plan where the opinions of local residents are excluded due to the lack of expert knowledge and limited participation and sought the village development plan driven by the voluntary participation of local residents by applying a rural forum targeting rural villages to solve the problem. As a result of the study, (1) the problem of the current village development plan should be made based on the participation of local residents, and (2) this problem has remained as an important challenge. Therefore, the village improvement activities that have reflected the opinions of local residents can be said to be (3) the process that seeks the change into the rural planning process led by local residents, and this study derived the ways to ensure the voluntary behavior of local residents, strengthen local residents' capacity to create on-going villages, and expand local residents' participation opportunities in the entire process of rural planning through the application of the rural forum. (4) Although it is generally difficult for local residents to propose opinions directly and exert influence in the rural planning and design process and it is not easy to reduce the difference in the perspective between the professionals and local residents, significance lies in the fact that local residents voluntarily determine the future of their region and derive the plan. Therefore, the experience of decision-making and consensus process through the rural forum can promote the sustainability of the village creation participated by local residents and the increase of local residents' role. This study took one village as an example to reflect the results applied to the rural forum, and it is difficult to determine that it has been fully verified with the method of residents' participation. Therefore, future studies to verify the effectiveness of village creation and seek the empirical utilization measures are needed more, and the operation of education programs and various support plans suitable to the capacity and level of local residents should be promoted rather than the traditional lecture-style stereotyped education in the future for sustainable rural development.

  • The combination of animals has been developed in each of the cultural spheres as a method of metaphor and symbolism of the cultural code. However, its symbolism is not a fixed constant, but a variable and relative constant. This work focused on its features in comparison with East Asian cultural spheres comedic stories and proverbs. Consequently, several features were identified. First, the combinations of animals in similar comedic stories and proverbs among Korea, Japan and China show a difference in point of view. Korean focuses on the difference of the two animals, but Chinese and Japanese focus on the differences in value and level. Second, the method of anthropomorphization is relatively more developed in China and Japan than Korea. The combinations of animals of Chinese comedic stories and proverbs particularly in the field of anthropomorphization, are most focused on age and sex of the animal. The animal's age or sex remains mostly undetermined in Korean animal's proverbs, unlike Chinese proverbs. On the other hand, two animals in Japanese comedic stories and proverbs are usually of the male and female gender from. Third, the combinations of animals of Chinese and Japanese focus on the animal's body and its characteristics of action. Chinese and Japanese combine the characteristics of the two animal's bodies and actions. This feature apparently caused the resultant combinations of the animal's body parts, for example, the Dragon. Understanding of the combinations of two animals is a good portal into the features of East Asian culture sphere.

  • Mt. Hee-yang is located in Mungyeong-si, Gyeongsangbuk-do, South Korea. Through the analysis and interpretations of twenty-two different ancient writings which covers Mt. Hee-yang, and three times of field studies, I tried to analyze the cognition of our ancestors in those days regarding Mt. Hee-yang. Since Mt. Hee-yang goes very deep in the mountain range, Mt. Hee-yang was recognized as appropriate place for seclusion or operating Byeolseo. From the era of Silla, in terms of Fengshui, Mt. Hee-yang was also interpreted as an image of either a phoenix flying into the sky(鳳凰登天) or a valley of a phoenix and dragon(鳳巖龍谷). This cognition comes from its formations of topographical features, and continued to the era of Joseon Dynasty. The purposes of excursion were to retrace the course of predecessors, to attain one's long-cherished desire to visit, or to enjoy holidays. From the analysis of Mt. Hee-yang's visitors, the average social status of them is lowered a lot around the end of Joseon Dynasty, compared with the early period of Joseon Dynasty. Studying the visitor's route of Mt. Hee-yang, I could see the places that are highly-recognized were the top of Mt. Hee-yang, Seonyudong(仙遊洞), Bakundae(白雲臺), Yayuam(夜遊岩). Mt. Hee-yang was recognized as Sun-kyung(仙境) where Sin-seon(a taoist hermit with miraculous powers; the sage of old) lives, and mostly it was main destination of visit while Bakundae(白雲臺) was perceived diversely on each visitor because of its strange scenery.
