This paper uses input-output techniques to analyze the impacts of the coastal and inland water transportation (CIWT) upon the Korean economy between 1990 and 2000. The impacts were identified by means of backward and forward linkages effects, production inducing and import-inducing effects, and commodity prices repercussion effects of the coastal and inland water transportation. The data of this study come from The Bank of Korea databases for Input-Output Structure of the Korean economy. The major findings in this study can, among others, be summarized: that the power of dispersion(=backward linkage effect) and the degree of sensitivity (=forward linkage effect) of CIWT are higher than those of the deep sea transportation sector and that it has higher production-inducing effect than the average of total industries, while it has lower import-inducing effect than the average of total industries.

Ciliates are a speciose protozoan group and their diversity is still not well investigated in Korea. From our field surveys, 18 unrecorded ciliate species were collected from a total of nine localities in Korea. The field surveys were conducted in 2018 and 2019, and the unrecorded ciliates were found from terrestrial (moss and soil samples) and inland water (river and lagoon samples) habitats. The morphology of these ciliates was studied using the observation of living and silver impregnated (protargol) specimens. The present species belong to five classes as follows: 1) class Spirotrichea - Gonostomum kuehnelti, Quadristicha setigera, Lamtostyla decorata, L. islandica, L. longa, Anteholosticha brachysticha, Pseudobirojimia muscorum; 2) class Litostomatea - Apocoriplites lajacola, Epispathidium amphoriforme, Protospathidium muscicola, Phialinides australis, Paraenchelys wenzeli, Rimaleptus similis; 3) class Nassophorea - Drepanomonas revoluta; 4) class Colpodea - Bryometopus triquetrus; and 5) class Oligohymenophorea - Cyclidium glaucoma, Epistylis pygmaeum, Pseudovorticella vestita. The globular macronuclear nodules of P. vestita were observed for the first time in the Korean population.

We have examined the influence of local wind on occurrence of fog at two inland areas, Chuncheon and Andong, in Korea. The surrounding topography of two inland areas shows significant difference: Chuncheon is located in the basin surrounded by ridges with north-south axis while Andong is located in the valley between the ridges with east-west axis. Occurrence of fog shows maximum in October at both sites but high occurrence of fog at Chuncheon is also noted in the winter. Occurrence of fog at Andong in October is much larger than that at Chuncheon. High occurrence of fog in October is due to favorable synoptic condition for fog formation such as weak wind, clear day and small depression of the dew-point. Fog occurrence at Chuncheon is closely related to very weak wind condition where wind speed is less than $0.5m\;s^{-1}$. The weak wind at Chuncheon in winter is due that pressure driven channeling wind (southerly) cancels out partly downslope northerly flow during nighttime. On the other hand, fog at Andong occurs well when wind is southeasterly which is thermally forced flow during nighttime. Southeasterly provides cold, moist air from the narrow valley to Andong during nighttime, leading to favorable condition for formation of fog.

As of late, people who enjoy fishing as a pastime in Korea has dramatically increased on the back of the increased national income and 5-day working system being in place. In the past, people used to fish in inland waters, but fishing on the sea has also shown a steady increase. The expanded fishing community along with increasing types of fishing, however, led to destruction of ecosystem by littering the waters of both inland and sea with wastes and reckless exploitation of fish resources. Fishing activities are usually taking place in inland waters, or on the sea, which is, by definition, a common property, and side effects such as free riding and diseconomy are frequently observed occurring. In other words, everyone can use the property free of charge(except paying fishing lot), and littering the waters with pollutants and wastes stemming from fishing activities is currently rampant. In this context, this paper studies the necessity of introducing fishing license system and its feasibility in Korea from a perspective to improve the national welfare through policy measures based on 'polluter pays principle' to prevent further environmental pollution in the fishing lot and preserve fishery resources. Study shows that introduction of Recreational fishing license system is urgently needed, but it is concluded that it should take more time to implement the system so as to accomodate the differing interests of all parties involved including recreational fishing industry, while strengthening public relation activities to solicit for the people's understanding of the system to be introduced.

In order to foster the minor enterprises effectively we will have to take a proper step to control and adjust the excessive competitions of large-enterprises and minor as well as among minor enterprises, We should promote the relationship serialized between minor - and large - enterprises and establish mediation and control organizations and governmental policies to create re-subcontract among small and medium enterprises. To help the development of medium md small enterprises in Jeon-Buk area, therefore, Kunsan city should be designated as a Growth Position City. The reason is as follows. 1) Because Kunsan is located in Middle Western Seaside geographycally, and in the central place of our country as a key point of sea-transportation, we can cultivate the national land widely. 2) As an ocean gateway city of Kum River basin, Kunsan is a good place that can reform Hoh-nam inland of Kwang-iu, Jeon-ju, I-ri, and like places as well as central inland area of Dae-jeon, Chong-ju, etc.. 3) Kunsan is an advanced-base for constituting an industrial region of Weatern roast that has a spacious coastral industrial region and is connected with inland industrial park of Jeon-ju and I-ri and Jang-hang, Bi-in, etc.. From the above reason. Kunsan should be designated as a growth position city that can induce and promote the development of center of Western coast.

컨테이너 화물의 물동량이 증가함에 따라 공컨테이너의 처리 요구량도 함께 증가하여 왔으며 이에 따른 공컨테이너의 재배치 문제에 관한 연구가 꾸준히 이루어져 왔다. 하지만 컨테이너화물의 처리가 공컨테이너의 처리와 함께 이루어지지는 않는다. 더욱이 우리나라 같이 ICD(Inland Container Depot)와 ODCY(Off-Dock Container Yard) 와 같은 내륙 거점이 많은 환경에서는 그 거점에서 필요로 하는 공컨테이너의 수요에 따른 재배치 연구가 필요하나 이와 같은 연구는 많이 이루어지지는 않았다. 이 논문에서는 컨테이너 터미널과 ICD, ODCY와 같은 거점에서 필요로 하는 공컨테이너의 수요량에 따른 합리적인 재배치 모형을 수립하고 분석하도록 한다. 또한 과거와 동일하게 시행되고 있는 현재의 재배치 방식을 개선하여 비용 절감 효과를 높이는데 도움이 되도록 한다.

Off the 1,572 km long coastline of Namibia lies known as the Benguela upwelling system, a very rich source of marine life supporting traditional and modern forms of fishery. Commercial fishing and fish processing is one of the fastest-growing sectors of the Namibian economy in terms of employment, export earnings, and contribution to GDP. The fishing industry has grown to the extent that it is currently Namibia's second biggest export earner of foreign currency after mining (90% of national output is marketed for export). In 2005, Namibia harvested about 552,164 tonnes of fish. The final value of processed products (export value) that year was around US$ 376.0 million. Besides the marine captured fisheries, Namibia also has a small but vibrant aquaculture sector. Inland captured fisheries exist in the north-east and north-west of Namibia where as commercial freshwater aquaculture of tilapia and catfish is also undertaken. The inland fisheries are mainly subsistence based and typically labour intensive, with low catch per unit effort. However the subsistence fisheries from these regions play a significant role in the lives of rural community. The domestic market for marine fish products is extremely limited due to the small size of the population (2 million). The fishing industry is a source of considerable employment for many Namibians. Huge potential to increase production exists in Namibia, unpolluted high quality marine waters, high natural primary productivity of the seawater, availability of inexpensive fish by-products from established fish processing sector for inclusion in wet aqua-feeds and well-established processing, packaging and marketing systems due to the marine capture fisheries that can be adopted for aquaculture purpose.

It can be important framework data to monitor the change of land-use pattern of river boundary in design and management of river. This study analyzed the change of land-use pattern of Gab and Yudeung River using time-series aerial images. To do this, we carried out radiation and geometric correction of image, and estimated land-use changes in inland and floodplain. As the analysis of inland, the ratio of residential, commercial, industrial, educational and public area, that is urbanized element, increases, but that of agricultural area shows a decline on the basis of 1990. Also, Minimum Distance Method, which is a kind of supervised classification method, is applied to extract water-body and sand bar layer in floodplain. As the analysis of land-use, the ratio of level-upped riverside land and water-body increases, but that of sand bar decreases. These time-series land use information can be important decision making data to evaluate the urbanization of river boundary, and especially it gives us goodness in river development project such as the composition of ecological habitat.

This study is change of the street space of the port city of Yokohama and the transformation process of the canal. modern port city Yokohama is a region that was responsible for the development of East-West maritime transport routes in Japan in the 17th century and the inland transportation through fishing villages and ports. it has also grown rapidly as a regional port and new port. In particular, through the revitalization of trade between foreign settlements and Japanese residents in the port area, the existing fishing area became a modern port city space. Yokohama went through the following process and grew into a modern port city. The construction of the port harbor and the maintenance of existing logistics functions, the formation of the central horizontal axis through maintenance of the fishing village, the construction of the logistics movement route to the inland area through the construction of the canal, the expansion of the horizon for fire prevention and fire restoration, The formation of a new settlement space according to the movement, the transformation of the existing religious axis by the combination of the elaboration and the introduction of modern transportation, and the spatial connection between the inland cities.
