In this study, a numerical particle tracking experiment was conducted to assess the distribution characteristics of freshwater exclusion resulting from the discharge of Gahwa Stream into Sacheon, Jinju, and Gangjin bays, located downstream of the Namgang Dam. The number of particles discharged into Noryang Channel, Daebang Channel, and Changseon Strait was compared by releasing 1000 particles through Gahwa Stream under three discharge conditions: no discharge, discharge during rainfall, and discharge during flood. Evidently, the percentage of particles in the Noryang Channel increased, whereas that in the Daebang Channel decreased as the discharge from the Gahwa Stream increased. Approximately 95% of the material located downstream of the Gahwa Stream generally escaped through the Daebang Channel. However, as the discharge from the Namgang Dam increased due to rainfall, the percentage of particles in the Noryang Channel increased, reaching 45.5% during floods.

This study is a novel attempt at a fusion of female-authored Chinese poetry and Daesoon Thought. Notably, this has style of fusion has never been attempted in classical literature studies or in studies on Daesoon Thought. This study will also clarify the the key concept of grievance-resolution (解冤 haewon) in Daesoon Jinrihoe through comparison with classical works. Choi Song-seoldang's poetry that was composed in the early 20th century, contemporaneous the emergence of Daesoon Thought, is analyzed here via the concepts of 'tranquility (平 pyeong)' and 'harmony (和 hwa)' under the framework of grievance-resolution for women. An effort is made to find a point of progression towards familial harmony (家和 gahwa) and Mutual Beneficence (相生 sangsaeng). Resentment (恨 han) from the perspective of a woman was expressed in her works such as Wang So-gun's Resentment (昭君怨 sogunwon), Self-Report (自述 Jasul), and An Original Rhyme of Song Seol-dang (松雪堂原韻 Song Seol-dang Won-un). Works such as Wishes on the First Day of New Year (元朝祝 wonjochuk) and A Spontaneous Poem (偶吟 Ueum) expressed the contents of wishing for familial peace. In the process of trying to resolve the grievances (冤 won) of her family, Song Seol-dang faced limitations, and felt resentment (恨 han) for her inability to become a man. She strived her whole life to embody 'tranquility' and 'harmony' as both are crucial components of achieving familial harmony. This thesis has an important significance in terms of academic expansion via the convergence of literature and ideas. In terms of Daesoon Thought, it is meaningful to examine concepts and literature within a context of fusion because this goes beyond research that focuses only on theory or ideology. It is also meaningful to confirm aspects of Daesoon Thought through the life and culture of the still traditional early modern era and to reveal how it still has the present-day significance that transcends time.

Heavy oil residue upgrading process was being used in conventional refinery process. Recently, as the importance of non conventional energy development is growing up, the commercial projects of heavy oil upgrading are getting more active than before. For having competitive business model in the resource competition, non conventional energy development should be considered as an important business strategy. In developing oil sands, extra heavy oil, and shale gas, canadian oil sands and extra heavy oil have great importance in substitution of conventional oil consumption. In oil sands development, the bitumen, which is extracted from oil sands, has great value after upgrading or refining process. Similar process is being used current conventional refinery process. The bitumen is highly viscous hydrocarbon. This bitumen includes impurities which can not be treated in conventional refinery process. As this reason, specified process is needed in bitumen or extra heavy oil upgrading process. Moreover, there will be additional specified facilities in the process of production, transportation and marketing. In oil sands, there are various kinds of commercial upgrading process. Extraction, dilution, coking and cracking method were being used commercially.

At the center of the Noryang waterway, the Gwangyang bay area (including the Yeosu Strait) is located at the west, and the Jinju bay area (including Gangjin bay and Sacheon bay) is located at the east. Freshwater from several rivers is flowing into the study area. In particula,r the event of flood, great quantities freshwater flow from Seomjingang (Seomjin river) into the Gwangyang bay area and from Gahwacheon (discharge from Namgang Dam) into the Jinju bay. The Gwangyang and Jinju bay are connected to the Noryang waterway. In addition, freshwater from Seomjingang and Gahwacheon also affect through the Noryang waterway. In this study, we elucidated the characteristics of the tidal exchange rate and residence time for dry season and flood season on 50 frequency, considering freshwater from 51 rivers, including Seomjingang and Gahwacheon, using a particle tracking method. We conducted additional experiments to determine the effect of freshwater from Seomjingang and Gahwacheon during flooding. In both the dry season and flood season, the result showed that the particles released from the Gwangyang bay moved to the Jinju bay through the Noryang waterway. However, comparatively small amount of particles moved from the Jinju bay to the Gwangyang bay. Each experimental case, the sea exchange rate was 44.40~67.21% in the Gwangyang bay and 50.37~73.10% in the Jinju bay, and the average residence time was 7.07~15.36days in the Gwangyang bay and 6.45~12.75days in the Jinju bay. Consequently the sea exchange rate increased and the residence time decreased during flooding. A calculation of cross-section water flux over 30 days for 7 internal and 5 external areas, indicated that the main essential flow direction of the water flux was the river outflow water from Seomjingang flow through the Yeosu strait to the outer sea and from Gahwacheon flow through Sacheon bay, Jinju bay and the Daebang waterway to the outer sea.

Owing to their high bioproductivity and unique physical environment, estuarine wetlands are gaining importance in national biodiversity management and habitat conservation. With regard to conservation and management of estuarine wetlands, this study analyzed the ecological characteristics of Gahwacheon Estuarine Wetland, an open estuary with various habitat types. Data from vegetation and biotic surveys have shown that 12 plant communities of five physiognomic vegetation types, including lentic herbaceous vegetation, halophytic herbaceous vegetation, and chasmophytic herbaceous vegetation. Due to the discharge of Namgang Dam and the effect of the tide, vegetation are distributed along the narrow waterside area. In terms of biodiversity, a total of 715 species, including 12 endangered wildlife species, were identified. Species diversity was relatively high in sections I and III where various riverbed structures and microhabitats were distributed. Due to the effect of the brackish water area following the inflow of seawater, endangered wildlife of various functional groups were also found to be distributed, indicating the high conservation value of that area. The collection of ecological information of the Gahwacheon Estuarine Wetland can be used as a framework for establishing the basis for conservation and management of the estuarine ecosystem and support policy establishment.

본 글에서는 건물 및 교량의 면진/제진 기술의 연구개발과 실용화 현황에 대하여 전반적으로 살펴보았다. 현재 면진/제진 기술의 연구는 매우 활발하게 진행 되고 있으며 여기서 그 전체를 서술하기는 어렵다. 고량의 면진/제진 기술은 새로운 내진기술로서 금후 고량의 다경간 연속화, 장경간화, 고교가화, 엄격한 용지조건 에서의 고량건설에 중요해질 것으로 생각된다. 현재 제진구조 시스템은 안전한 거주 셩의 관점으로부터 중소지진 및 강풍 등에 대한 외란대책으로서 실용화 기술이 진행 되고 있다. 실무적인 관점으로부터 주로 구동장치의 개발이 중심이 되고 있으며 이것에 의하여 제진구조 시스템의 성능이 결정된다고 해도 과언이 아니다.
