Geochemical Exploration Technics in the Pungchon Limestone Area
문건주,Moon, Kun Joo The Korean Society of Economic and Environmental G 1990 자원환경지질 Vol.23 No.4
우리나라에서 중요한 금속광상인 상동 중석, 연화 연-아연, 거도의 동-철 광상은 모두 태백분지내 함백향사 남익부에 위치하고 있다. 이들 광화작용은 대체로 동서 주향에 25-30도 북향한 경사로 놓여진 캠브리아기의 묘봉층내 석회암 협층과 풍촌 석회암에서 일어났다. 함백향사의 북익부에는 동일한 지질내에 동일형의 광상이 노출되어 있지 않아, 이 지역에서의 잠두광체를 찾기위한 수단으로 알려진 상동광산 지역에서 암석지화학적, 특별히 Si, Ca, Fe 및 탄소 안정동위원소를 이용한 탐사연구를 시도하였다. 광화대와 비광화대의 석회암 사이의 CaO와 $AL_2O_3$ 함량은 큰 차이를 보이고, 탄소동위 원소 분석결과 역시 ${\delta}^{13}C$ 값이 광화대에서 더 낮은 값을 보이는 바 그 내용은 아래와 같다. 비광화대 광화대 CaO 51.3% 43.5% $Al_2O_3$ 0.6% 2.4% ${\delta}^{13}C$ -0.39 permil -0.56 permil $Fe_2O_3$ 0.9% 1.4% $SiO_2$ 3.0% 2.4% 광화대내의 풍촌석회암의 Si 함량이 감소한 것은 앞선 연구(Moon. 1987) 결과와 상치되는 바, 광화대내의 석회암중 Al 함량이 증가한 사실을 확인한 사실을 근거로 생각해 볼때, Si의 감소는 열극, 균열, 또는 소규모의 단층올 따라 주로 발달된 변질물의 증가에 따른 결과로 유추되기도 한다. 따라서 광화대내의 Si 와 Al 함량이 보여주는 현상은 화강암류로부터 전달된 열의 영향으로부터 기인된 것으로 상위 지표부의 석회암에 이로부터 광화활동이 이어진 것으로 여겨진다. 만약 함백향사의 북익부에서 풍촌석회암의 Fe, Al의 함량이 평균 함량치 보다 높을 뿐만 아니라, Ca와 Si는 낮고 Ca 함량과 ${\delta}^{13}C$의 값이 평균치보다 낮은 값을 보이는 경우는 잠두광체 탐사에 이용될 가치가 있다고 본다. Most of significant ore deposits in South Korea such as the Sangdong W - Mo, the Yeonhwa Pb-Zn and the Geodo Cu-Fe skarn ore deposits occur at the southern limb of the Hambaeg syncline in the Taebaeg Basin. The mineralization took place in the interbedded limestone of the Myobong Formation and the Pungchon limestone of the Great Limestone Group of the Cambrian age, generally striking E-W and dipping 25-30 degrees north. There are no outcrops of the skarn-type orebody at the northern limb of the syncline. In order to find a clue of a possible hidden orebody localized at the limestones in the northern limb, a lithogeochemical exploration by using carbon isotope and some elements such as Si, Ca, Fe and Al at the Sangdong Mine area has been attempted as for a modelling study. For this study, 45 samples from the Pungchon limestone which do not show any megascopic indication of mineralization have been taken in both the mineralized zone and the unminerallized zone at the Sangdong Mine area. Analytical data show that there are big differences in the contents of CaO and $Al_2O_3$ between the Pungchon limestone of the mineralized zone and that of the unmineralized zone. Carbon isotope data exhibit that ${\delta}^{13}C$ values of the Pungchon limestone in the mineralized zone are highter than those in the unmineralized zone. The difference in the analytical values of CaO, $Al_2O_3$ and the carbon isotope between the mineralized and the unmineralized zones is as follows ; Unminerallized zone Mineralized zone CaO 51.3% 43.5% $Al_2O_3$ 0.6% 2.4% ${\delta}^{13}C$ -0.39 permil -0.56 permil $Fe_2O_3$ 0.9% 1.4% $SiO_2$ 3.0% 2.4% The decrease in the Si content of the Pungchon limestone in the mineralized zone is contrary to the result of the previous study (Moon, 1987). On the basis of identification of the increase in the Al content of the limestone in the mineralized zone, it could be deduced that the decrease in the Si content of the Pungchon limestone might be due to the result of increase in the alteration products mainly occurred along fracture-system such as joint cracks or minor faults and that the phenomena shown by the Si and Al content in the mineralized zone might be derived from the thermal effect of granite extended mineralizing activity to the overlied limestone on the surface. Higher mean values of Fe and Al as well as lower mean values of carbon content and the ${\delta}^{13}C$ than mean values of those in the Pungchon limestone at the northern limb of the Hambaeg Syncline may be applicable in exploration for blind orebodies.

The electrochemical property in H_(g)-(x)_Cd_(x)Te(x= 0.198) by anodic oxcidation have been studied in the standard aqueous solutions(pH=6, 9, 12) of ethylene glycol(90%) and H₂O-KOH(10%). At range of potential -0.1V ~ + 1.2V, 3 oxcidation peaks appeared. The rich residue Hg of HCT surface was related to oxcidation process of depleting Hg²+ ion in aqueous solution. Most of oxcidation materials were considered TeO₃ HTeO₃ HHgO₂, HTeO₂, TeO₂ and very little of Cd(OH)₂. The higher PH degree, the faster oxcidation process.
Lagrangian Transport Model에 의한 擴散方程式의 數値解析
朴文浩,韓健淵 慶北大學校 1983 論文集 Vol.35 No.-
The mathematical modeling of the dispersion behaviour in the river was studied. The solution approach to the convective-diffusion equation uses a Lagrangian reference frame which greatly simplifies the mathematics of solution procedure and dramatically reduces errors caused by numerical dispersion. The dispersion analysis of the conservative material was made and the accurrcy of the model was also discussed. The model should be calibrated by field data, and expected to be developed for the simulation of the various pollutants such as BOD, DO, nitrogen, phosphorous and of the unsteady flow in the river.

All the actions in urban planning and architecture can exert an influence on townscape by constructing artificial structures(buildings and facilities for example). So a planner tries to predict and to evaluate his plan by simulation the influences of the construction activities on the townscape before the plan is executed. The popular simulation methods are picture composition, model making, bird's eye view drawing, and Computer Aided Design(CAD). CAD can display realistic image by the digital drawing data which are input by digitizer, scanner, or keyboard, and plot output on paper very fast and repeatedly. CAD system is now becoming a feasible reality in many fields technologically and economically. This paper aims to show some application of CAD System in urban planning and urban design on the scope on Visual simulation of townscape, and to find some reliable and objective methods to control the shape, height and size of building. As a case study we explain the Wolpyung Park Region where many high-storied building(like apartments and office building)have been builted and many parts of the Green space of Park are hidden by these buildings.

오문완,김유미,도회근 울산대학교 사회과학연구소 2000 사회과학논집 Vol.10 No.1
우리나라에서 인권 보장의 현실을 생각할 때 우리는 앞으로도 많은 과제를 해결해야 한다. 특허 노동인권의 보장 문제가 되면 더욱 그러하다 그리고 문제를 해결하는 데는 기본적인 시각의 정립이 필요한데, 우선 노동인권의 성격에 대해 제대로 이해하고 있어야 한다. 또한 사회적 기본권의 구체적 권리성을 인정하는 견해에 주목할 필요가 있다. 아울러 노동인권의 보장에 관한 국제적인 움직임을 주시해야 한다. 노동시장의 변화하는 모습 역시 놓쳐서는 안된다. To consider the reality of guaranteeing human rights in Korea, there are many problems to be resolved, especially in the field of labor. Most of all we should settle our position about labor rights and the character of those. And it may be helpful to examine the opinion approving the concrete aspects of the social rights. We should not neglect to pursue the international movement of guaranteeing labor rights and the change of labor market.
