The following research of the road network of Jeju-Eupseong during Daehan Empire period has a twofold purpose: to study some characteristics of the road network at that time; and, to restore it to the original form of that period before a newly constructed road, called Shinjakro, has been established. As an attempt to trace the old shape of Jeju-Eupseong, this study analyzed some historical factors based on the first land cadastral map which was made in 1914, including outskirts of Jeju-Eupseong; such as castle itself, castle gate, road, bridge, lots of land, etc. Then this study also tried to restore the old road network of Jeju-Eupseong, through finding the original land-lot shape in the land cadastral map. There was five Shinjakro made between 1914 and 1917. The road network before then was composed of the double east-west axes and the single north-south axis. These axes was connected to some important place of the inside of Jeju-Eupseong; such as castle gates, fountains, Gaek-sa, etc. There were many branch lines between these main axes at about 80-120m intervals. Also there was an outer road along the outer wall of castle, connected with each castle gates. Especially, the north-west axis was the baseline which divided into two large parts, a government office area and non-government area (housing and commercial street for the people). Finally, this paper examines that the road network of Jeju-Eupseong was the true result for the efficient function of the city, especially considering natural geographical conditions and environment of living of that time.

This writing is to understand some trends and its meaning of Regionalism Architecture in Jeju Island since 1950's.This thesis began with an interestin the identity crisis implicitin the simultaneous striving formodernism and the so-called regionalvalues in Jeju Island.Regionalism is a response in architecturalterms to re-establish continuity in a given place between pastand presentforms,and also a uniqueresultrelated to particularplaces,culturesand climatesin region.Thisisone wayoflookingattheissuesofregionalidentity. Thestudy began by observing thegeneralcharacteristicsofcontemporary ideason Regionalism inJejuarchitecture.Thismeansthattracingthehistoryofdevelopmentof Regionalism architecture in research area is notthe focus ofthis thesis.The thesis demonstratesthatRegionalism architecturesin Jeju showssometrendsrelated to the local cultural elements (or ideas) such like traditionalarchitectural forms,natural environment,local construction-materials,etc.In summation,in the perspective of Regionalism architecture,mostofbuildingsin Jeju bring outthem only asvernacular architectureasitwasonceproduced,by thesimplecombination andimitation without anycreativeinteractionoftheregionalculture. Istressthe pointin thispaperthat,in overthelastfifty years,therehavebeen very narrowed attemptstodesign theregionalvaluesin themain,and alsopointout thatthereareproblemsinthemannerinwhichlocalarchitectshavegoneabouttrying to define the regional themes.So,a grate depth is required to understand the phenomenonthatJejuareaiswithitsvariousnuancesoftraditions,art,culture,climate and lightand then to reinterpretitinto the modern building type with allthe high sense.In addition to that,someconclusionsarereached on futuredirectionsand the significanceofthestudy.

This thesis is a historical research about the Foreign Settlement at Mokpo as the fourth among the Open Ports which express the historical characters of Korean Modern, as a city which did not exist before the Korean Modern. So I analyzed positively the process of establishment and the process of urban form during the period which contained the characters of Concession, from 1897 to 1910. Even though the urban basic form of the Foreign Settlement at Mokpo was planned by Korean Goverment, it's townscape was changed to Japanese style by Japanese since Mokpo port was opened. Because it had settled by Japanese residents which had majority. But I found that the urban form was not composed by the Modern urban planning theory or method, but by the existing conditions such as topography and roads. The center in the settlement had shifted from the front region of Japan Consulate to the East region which was in the vicinty of Korean village. And also former internal oriented urban form had changed to the relevant composition with Korean village. All the changes in the Foreign Settlement at Mokpo was made by the Japanese which had majority, and it is a good example which expresses Korean Modern history.

This study was conducted to determine the effects of organic fertilization rates on the nutrient accumulation and recovery in radish (Raphanus sativus L.) as well as growth and yield of radish in Jeju island. An understanding the relationships between organic fertilization rate, crop nutrient recovery and crop yield can assist in making organic fertilizer recommendation which balances crop value and environmental risk in organic cultivation. Nitrogen (T-N), phosphate (P2O5) and potassium (K2O) were applied at 0, 115-35-40, 230-70-80 (standard application rate), 460-140-160, 230-200-100 (recommended application rate) and 158-53-35 kg/ha (customary application rate), respectively as the broadcast application of mixed organic fertilizer (N 4.5% - P2O5 1.5% - K2O 1%) in combination with langbeinite (K2O 22%), 100% at sowing period. The organic fertilizer was made of organic materials like oil cakes. Total yield of radish, as fresh weight of roots, increased with increasing organic fertilizer doses to a maximum at rate of standard or soil-testing application. Nitrogen, phosphate and potassium accumulations of radish increased curvilinearly with increasing organic fertilization rate to a maximum at rate of N 460 - P2O5 140 - K2O 160 kg/ha. However, nitrogen, phosphate and potassium use efficiency of applied organic fertilizer decreased curvilinearly or linearly with increasing organic fertilization rate. Application of organic fertilizer in combination with langbeinite (as a potassium source) had significant effect on the yield of radish. Organic fertilization on a basis of standard or soil-testingapplication rate is recommended for maximun radish yield in organic cultivation.

The conditions of cold stroage of Citrus unshiu Marc. var. okitsu produced in Cheju were investigated. The changes of peel moisture contents soluble solids, total sugar, vitamin C and density were slightly occured, and decay ratio was below 20% on keeping freshness relatively till late of March during cold storage. After thats decayed citrus fruits were increased gradually mainly from cold injury with lower temperature and high humidity. The loss of fruit weight, decrease of fruit hardness, and decrease of acid content were occured gradually during cold stroage. Because of the difficulty of long term storage for Citrus unshiu, the conditions and periods of cold storage would be determined after considering the physicochemical properties of fruits every year.
