Forest resources is universally useful, it is especially important in promoting the national economy, conservation and social welfare. But, in Korea, due to under trained cutting in the past forest resources brought great problems in meeting the demand for timber and fuelwood supply, and in protection of natural environment against public nuisance because of industrialization. Forest land in Korea, as of the end of 1973 is 6.641,000㏊ or 67% of the total territory, but total growing stock volume as of the end of the same year is 74,466,000㎥ and the average stock per ha is no more than 11.2㎥ which accounts for really poor figure compared with the international standard. On the other hand due to the successful result of the economic development plan the trend is toward the rapid increase of timber demand with the high growth of national economy. But useable volume is estimated at only 6,000,000㎥ and such scanty forest resources would be rapidly decimated to meet an annual demand of 7,000,000㎥. Therefore, to. increase forest growing stock and sustain wood supply, we must restrict tree felling and economize in wood consumption through better utilization, importing to meet the supply deficit. Accordingly, to increase forest resoures and future wood supply policy should be as follows. Reforestation of the devastated forest land is urgently needed in order to improve productivity and increase resources to the economic benefit of the people. The broken small-scale forest land ownership which is the obstacle to improve the productivity should be renovated in private forests, and to attain the above objectives adoption of rationalized forest management plan, improvement of forestry technique and enocouragement of private investment by forest owners should be executed. The general reforestation work is essential in the long program of wood supply, but reforestation does not affect the relation of wood demand and supply directly, because a seedling needs a long time to grow to maturity. In national forest it is necessary to complete reforestation on open land and regenerate the slow growing hardwood stands with conifers to increase productivity per unit area. At the same time in non-national forest the self-supported reforestation should be encouraged by the establishment of a long-term loan system, and expedited investment to make the resource of revenue for public organization. In order to achieve the above objects we must secure superior seeds from seed-tree forest establishment well managed, produce vigorous seeds, and keep the principle of right tree on right site. In wood demand and supply limitation of domestically produced timber supply to specialized emergency use within the permissible felling limit should be kept, and improvement of wood utilization, the use of wood substitutes and wood import to supply deficit should be encouraged and we must try hard the development of use method for hard wood species. Especially for import of wood supply deficit the authorities should endeavor to develop forests and sustain wood supply demanded in Korea. To minimize the various forest damages by artificial nuisance, insects, diseases and forest fires we must develop the national movement and strengthen the forest protective organization. Technical improvement of silviculture, forest management, protection and utilization are demanded for better forest income and increase of forest productivity, therefore we must enforce the forest research work to improve technique and disseminate it through extension work by the field guidance of the forest officials, at the same time national movement for the protection of nature and enforcement of the countermeasures for minimizing of public nuisance should be demanded.

기획Ⅱ : 북한의 농,어업실태와 남북한 협력방안 ; 북한의 어업실태와 남북어업협력 추진 방안에 관한 고찰

이광남 평화문제연구소 2001 統一問題硏究 Vol.13 No.1

남?북어업협력사업은 크게 어선어업과 양식업으로 대별할 수 있으며, 이중 어선어업의 경우는 서해안 어업인들의 반발 등으로 인하여 사업승인이 불허되었고, 동해안의 경우는 조업수역에 대한 어장성 정보 부족, 동해안 지역 어업인들의 반발, 대표성 문제 등으로 사업의 추진이 어려운 실정이다. 또한, 양식업의 경우도 합작 추진되고 있으나, 남측이 희망하는 투자지역이 북한측 사정으로 변경됨에 따라 투자금액이 축소되는 등 사업이 답보상태로, 아직까지 가시적인 성과는 없는 것으로 알려져 있다. 이러한 문제점을 해결하기 위해서는 최소한 협력 초기단계에서 대다수 어업인의 참여와 이익을 위하여 이해당사자인 어업인 및 단체의 의견수렴 과정과 민간차원의 생산자 단체인 수협중앙회가 주축이 되어 사업 추진하는 방안이 강구될 필요가 있다. 북한의 어업실정은 장비의 현대화가 필요하며, 양식업에서도 어려움을 겪고 있어, 이에 대한 지원을 요청하고 있는 실정이다. 어업협력의 활성화를 위하여 남북협력기금이나 수산발전기금을 초기 협력단계에 지원해 주는 방안이 강구되어야 하고, 정부의 정책적 배려가 필요하다고 판단된다. 제도적인 문제로는, 수산관련 법규 정비가 요구되며, 남측의 어업인 단체와 북측의 책임있는 기관간에 어업공동위원회를 구성하여 운영하는 제도적인 장치가 필요하다. 마지막으로 어업분야 협력은 생산기간이 짧아 사업추진이 용이하며, 상호 실익을 도모할 수 이을 것으로 기대되는 것은 사실이다. 북한은 전반적으로 경제기반(인프라)이 열악하기 때문에, 경제적 이익측면 보다는 동족애 차원에서 협력을 추진하는 등 거시적인 시각 및 접근방법이 절실히 요구된다.

In the recent WTO/DDA negotiations, discussions are progressing to forbid fishery subsidies which have negative effect on the natural environment and the fishery resources and to lower or to eliminate the tariff/non-tariff barriers that distort trade liberalization. As a result, linking to the weak structural environment of Korea’s fishing villages; such a scheme has jeopardized the livelihood of fishermen who settle down in local fishing harbors. Against this backdrop, the government is attempting to positively respond to changes in the fishing environment in a number of different ways: promotion of fishing tourism,fishing harbor reinforcement in function, developing fishing villages, and harbors. With respect to investment by priority in fishing harbor development, it is very important to appropriately select investment targets based on objective criteria. A small number of harbors are chosen and investment plans by harbor are systematically devised, economic feasibility and the effects of investment are analyzed and reviewed in relation to each target harbor. This paper is designed to review and assess objective evaluation methods and the degree of importance for the designation of target harbors, dealing with local harbors in Chung Nam Do as a model. Each local government has tried to reorganize existing harbors and develop new harbors,considering a fall in the number of fishing vessels and the expansion of maritime leisure activities. In order to overcome the limit of existing harbors in function, to raise the income of fishermen, and to activate tourism, they have shifted their focus from simple functions such as vessel evacuation and anchoring to harbor beautification, which can work as a basis for fishing tourism. This paper points out that the AHP analysis method for prioritizing local harbors in Chung Nam Do should help to be chosen target harbors in other cities and provinces. Each local government has attempted to reorganize existing harbors and to develop new harbors, taking into consideration the decline in the number of fishing vessels and the expansion of maritime leisure activities. In order to overcome the limited number of functional harbors, to raise the income of fishermen, and to boost tourism, they have shifted their focus from simple functions,such as vessel evacuation and anchoring, to harbor beautification, which can work as a basis for fishing tourism. This paper shows that the AHP analysis method for prioritizing local harbors in Chungcheongnamdo could aid in the effective selection of target harbors in other cities and provinces.

모사 이동층 반응-분리기의 해석에 관한 연구 : Ⅰ. 선형 등온식 영역에서의 고찰 Ⅰ.The Study on the Linear lsotherm Region

이광남 안성산업대학교 1999 論文集 Vol.31 No.-

The esterification was performed by using a Three Section Simulated Moving Bed Reactor(SMBR) which consists of purge, pre- and post -feed section. The performance was compared with the batch reactor through the numerical simulation. The plug flow model with the reaction term was presented to estimate the concentration profiles of SMER. The numerical values could be calculated by orthogonal collocation method which can simulate the bed shift by rearranging the concentrations corresponding to the collocation points backward, by one bed, at the end of a switch time. To get the desired concentration profiles in the linear isotherm region, the criteria of proper flow condition suggested in this work should be satisfied. Under the proper flow conditions, the esterification conversion was increased to 96.2% beyond the equilibrium conversion of 63%.
