1. After the Chu Dynasty(周代), we can confirm the fish shape mark made of stones as the relics of the Chunkuk dynasty(戰國時代). In the Shu Dynasty(隋代), the system of bamboo and the rabbit shape mark made of silver into the fish shape mark. As it were, made of bamboo or siltier changed into the fish shape mark made of jade, gold, silver or wood. 2. In the Dang Dynasty(唐代), the used the fish shape credit mark made of jade, gold, silver, copper or textile, according to their classes. According to one's posit the man who wore purple, red coat, credit mark made a gold and silver. attached with putting them in fish bags. 3. In the Ryo Dynasty(遼代), there was also a system of attaching marks. The emperor was hanging the fish shape and the officials attached the double fish shape to the common dress. fish shape of jade. gold, amber, agate, silver or copper. without any fish bag. 4. The Song Dynasty(宋代) followed the system of the Dang Dynasty they used only the fish shape bags without marks in them. Hanging the fish shape bags made of gold and silver at the back side of the belt. 5. The Gin Dynasty(金代) carried out the system of made jade, gold or silver like the Dang, Song and Ryo Dynasty. In the Sejong Kingdom a system of paper card was carried out as the credit mark of the eighth and the ninth grade. 6. In the Ming Dynasty(明代), the military official general attached the golden, silver, ivory of jade, wood and copper cards with their positions and names. 7. Following the Dang Dynasty, Japan made of fish shape bags to their clothes. Colors of their fish shape marks were same as their clothes. They made the marks, such as crystal, cow's horn, lead and nickel and plated them with gold or silver. 8. In Korea, Pohai(발해) established the fish shape credit mark differed in material. gold, silver or copper according to their positions. We can confirm the Unified Silla(南國;統一新羅), carried out the system of attaching the fish shape in Chonma Chong(천마총), Golden Crown Chong(金冠塚), the King's 13-17 belt ring unearthed at the north part of Court South threat Chong(황남대총), the fish shape golden or silver, to their purple or red ceremonial coats. In the Koryo Dynasty(高麗), like the Dang, Song and Pohai, they attached the fish shape golden or silver marks, to their purple or red ceremonial coats.

This paper presents the implementation of a control system of pellet boiler using wood pellet as carbon neutral material. The system also has the additional features to provide remote controlling and monitoring based on home networking technology through either public switched telephone networks or mobile communication networks. It consists of three kinds of sub-modules; a main controller provides basic and additional features such as a setting of temperature, a supplying of wood pellet, a controlling of ignition and fire-power, and a removing of soot. The second is temperature controller of individual rooms which is connected to the main controller through RS-485 links. And interface modules with PSTN and mobile networks can support remote controlling and monitoring the functions. The test results under the heating area of $172m^2$ show a thermal efficiency of 93.6%, a heating power of 20,640kcal/hr, and a fuel consumption of 5.54kg/hr. These results are superior to those of the conventional pellet boilers. In order to obtain the such high performance, we newly applied a 3-step ignition flow, a flame detection by $C_dS$ sensor, and a fire-power control by fine controlling of shutter to our pellet boiler.

This study found that La hija del mar (1859) by Rosalía de Castro describes, as the background to the work, the lives of Galicians, along with the movement of the sea, scenes of the coast, storms, and lively plants in Muxía, a small city of Galicia and Cabo de Finisterre. It was shown that the nature of Galicia, as described in the work, is a beautiful site where fishermen and farmers live among the full aroma of plants and flowers, as well as being a subject of fear to the people there. Furthermore, it was also shown through the funeral process, along with a depiction of the natural environment, the unique place of Galicia is part of the traditional heritage that the Galician people have preserved, in which Roman Catholic rituals are mixed with superstitious rites. Moreover, the author shows through a description of the excessive drinking culture of Dionysian rites or Libation rites that Galicia is a land with longstanding and profound folk customs, as well as a special culture. It was proved that the work is a specific representation of the author's perspective. Thus, Rosalía depicts the lives of people and the natural environment, which have not been examined profoundly, although they always existed in Galicia. This provides space where the external reality of Galicia and part of the identity of Galicia can be elucidated.

This thesis investigates wrote by Lee Han Jin who edited "Chung Ku Young Un(靑丘永言)" with supposition that was affected by Lee Han Jin's literary activity and poetic direction, and Wayu(臥遊) was enjoyed by Sajok(士族) in the late Chosun Period. Lee Han Jin kept company with The Yeonam Faction and their friendship was based on Lee Han Jin's blood-relationship. Lee Han Jin's musical sense and poetic direction are verified by records about their poetic activity. In his old age, Lee Han Jin retired in the Yeongpyeong of Gyeonggido and edited "Chung Ku Young Un", Lee Han Jin's poetic direction is also verified by Sijo's theme which was included in "Chung Ku Young Un" and Lee Han Jin's Sijo. Meanwhile, Kyunghwasajok(京華士族) in the late Chosun Period wanted to overcome their situation that they could not leave city by imagination about landscape. That activity was Wayu. They didn't consider whether they see landscape, and they made good use of many genre of literature for effective Wayu. Lee Han Jin and his group's literary activity was formed by that cultural air. Lee Han Jin wrote though his retirement in mountain. It was also for effective imagination about landscape that he didn't see. So unworldly landscape was appeared in compared to other fishermen motif poems. The tension between Situation that he couldn't see real landscape and desire for effective Wayu get solved by form named that have distinct characteristic as a Jipgusi(集句詩).

Hydraulic and numerical models were applied to design the emergency spillway of ImHa multipurpose Dam. For the numerical model, FLOW-3D was used to evaluate the three-dimensional flow in the spillway. The results of hydraulic model were compared with those of the numerical model which were separated into four zones such as approaching zone, weir zone, transition & tunnel chute zone, and dissipator zone. Moreover, for optimum design of the spillway, the hydraulic and numerical models were performed for the basic plan. Solving the problems of the basic plan, the optimized alternative design was proposed. The numerical models for various conditions of the spillway were performed, which is not always feasible in the hydraulic models. Verified by using the hydraulic models, the optimum alternative design was proposed.

여수로는 방류량 월류시 한계류 상태와 고유속의 사류상태가 복합적으로 일어나는 흐름형태를 가지고 있어 여수로의 방류능력에 대한 평가시 수치해석 및 수리모형 실험을 통해 검증하고 있다. 여수로의 방류능력은 여수로 월류부 전면부 바닥고, 월류부 상 하류 경사, 월류웨어고 뿐만 아니라 교대 및 교각의 형상에 의해 영향을 받는다. 또한 월류웨어부를 지나 사류의 흐름양상을 보이는 천이부의 형상 및 후면 교각의 연장에 따라서도 급경사수로부의 흐름이 급변하게 된다. 국내 대부분의 여수로는 전면부의 교각(Pier)형상이 구조적인 안정성을 이유로 직벽형 설계방법을 일반적으로 채택하고 있으며 국내 및 미개척국(USBR)의 설계기준 또한 여수로 교각과 교대부의 평면 형상만을 고려할 수 있도록 제시하고 있어 국내 대부분의 수리 구조물들이 획일적인 구조물 형상을 벗어나지 못하고 있는 실정이다. 본 연구에서는 수치 및 수리모형 실험을 통해 국내 대댐에 설계되어 있는 직벽형태와 본 연구에서 제시하고 있는 켄틸러버형의 교각형상에 따른 여수로의 수리적 흐름양상 및 방류능력을 비교하여 그 효과를 검토하였다. 검토결과 켄틸러버형태의 교각이 설치된 여수로의 경우 직벽형에 비하여 전면부 수위상승 및 흐름교란이 적게 발생하였으며, 방류능력 또한 개선되는 결과를 나타내었고, 후면 교각의 연장이 길고 점차 축소될수록 급경사수로부의 흐름이 안정적인 것으로 나타났다.
