Seawater circulations between a bay and the open sea play an important role to make the ecosystem healthy, providing nutrient and oxygen to the benthic environments and cleaning up pollutions. The health of the benthic environment in a bay is closely related to the flushing characteristics of seawater. In this study, to estimate the seawater distribution and circulation characteristics of benthic environment in the Geunso bay, we calculated the hydraulic turn-over time by a hydro-hypsographic analysis. Digital elevation model (DEM) which was generated using waterline method based upon remotely sensed data and water depth of the subtidal zone estimated by echo-sounding survey was applied to the hydro-hypsograhic analysis through a geographic information system (GIS) spatial analysis. The results showed that 95% of the total area of the bay was tidal flat and the hydraulic turn-over time was 1.03 tidal cycle, which indicated that the flushing characteristics of the Geunso bay was very good. Geunso bay was revealed to occupy relatively wide area of benthic environment and to have relatively big tidal range over other domestic and foreign coastal environment, therefore it could have a better seawater circulation characteristics. This result can be effectively applied as fundamental information to establish the system for a quantitative estimate of health of coastal environment in the west coast of Korea and manage the ecosystem in benthic environments.

"zhenjiusunanyaozhi(鍼灸素難要旨)" is composed of three volumes and published in 1529 by Gao Wu(高武). Gao Wu(高武) is skillful in astronomy, the art of war and the law as well as a medical practitioner in Ming Dynasty. The books he wrote "zhenjiujuying(鍼灸聚英)", "zhizhi(直指)", "douzhenzhengzong(痘疹正宗)", "shexuezhinan(射學指南)", "zhenjiujieyao(鍼灸節要)". "zhenjiusunanyaozhi鍼灸素難要旨" is written by classifying the origin of acupuncture and moxibustion. In other words, it is edited by classifying the contents related to acupuncture and moxibustion out of the ancient Chinese medical book "yellow emperor's canon of medicine and yellow emperor eighty-one difficult" in which are composed of 3 volumes as follows, Volume 1 says the main diseases on "the nine acupuncture needles figure" (九針圖), "the reinforcing and reducing the meridian" (補瀉), "the needle depth" (針刺深淺), "the five shu points - metal, wood, water, fire, earth" (正,滎,輸,經,合) based on 18 chapters in terms of acupuncture in "yellow emperor eighty-one Difficult "難經"", in which it quotes the annotation of "the difficulty by the original meaning "難經本義"" written by Hua Shou(滑壽) in Yuan Dynasty. Volume 2 is composed of 2 parts. Part 1 says the method of treatment on 36 Chapters, the method of acupuncture use in the Linshu "靈樞" and the Suwen "素問" such as "the rule of acupuncture use" (用針方宜), "the nine-pin method" (九針式) and "the nine-pin to only use the time appropriate to consider nature of Heaven, Earth and person" (九針應天地人時以起用) etc., Part 2 says "the five difficult acupuncture(五亂刺)", "the rise and fall of energy and blood(氣血盛衰)". "the pain tolerance(耐痛)" and ect., in which are in terms of method of treatment collected the original texts of 59 chapters on acupuncture to each disease and of 8 chapters on moxibustion in the Linshu "靈樞" and the Suwen "素問". Volume 3 includes 10 chapters in which consist of "the stabbing to disease in 12 meridians (十二經病刺)", "the eight extra meridian disease (寄經八脈病)", "the twelve meridians(十二經脈)", "the fifteen collaterals (十五絡脈), the twelve meridian muscles (十二經筋)", "the acupoint (孔穴)" and etc. This is the book edited comprehensively by classifying the contents on the theory of acupuncture and moxibustion and the circulations of meridians in "yellow emperor's canon of medicine and yellow emperor eighty-one difficult" and there is no case story in particular except his comments in person. This study is for the purpose of helping researching and developing acupuncture and moxibustion and applying their clinical training.

Land-Ocean Interactions in the Coastal Zone (LOICZ) models for nutrient budgets were used to estimate the seasonal capacity of the Youngsan Estuary and Youngam-Geumho Estuary to sink and/or supply nutrients such as dissolved inorganic phosphorus (DIP) and nitrogen (DIN) to provide an understanding of the behavior of the coupled biogeochemical cycles of phosphorus and nitrogen in the estuaries (Youngsan Estuary, Youngam-Geumho Estuary) near Mokpo Harbor. During non-stratified periods (May, September, and November, 2008), simple three-box models were applied in each sub-region of the system, while a two-layer box model was applied during on-site observation of stratification development (July, 2008). The resulting mass-balance calculation indicated that even after large discharges from artificial lakes (in May and July), DIP influxes due to a mixing exchange ($V_{X-3}$, or $V_{deep}$) were more than terrigenous loads, indicating the backward transportation of nutrients from a marine source. The model results also indicated that for nutrient loads (DIP and DIN fluxes) in September, an extreme congestion of nutrients occurred around the mouths (sub-region III of the model) of the estuaries, possibly due to an imbalance in physical circulations between the estuaries and offshore locations. In November, the Youngam-Geumho Estuary, into which freshwater was discharged from artificial lakes (Youngam and Geumho Lake), showed nutrient enrichment in the water column, but the Youngsan Estuary showed nutrient depletion. In conclusion, to efficiently control water quality in the estuaries near Mokpo Harbor, integrated environmental management programs should be implemented. I.e., the reduction of nutrient loads from land basins as well as the deposit of nutrient loads into adjacent coastal lines.
