Thirty one species of weeds were surveyed on the first year pastures. Two species of them were unedible and noxious. Dominance were in order of Dactylis glomerata > Trifolium repens > Centella > actaica Digitaria Sanguinalis > Festica arundinacea. 2. Thirty two species of weeds were surveyed on the second year pastures. Four species of them were unedible and noxious. Dominance were in order of Dactylis glomerara 〉Trifolium repens 〉Centella asiatica 〉Zoysia japonica 〉Imperata cylindrica. 3. Thirty five species of weeds were sorveyed on the third year pastures. Seven species of them were unedidle and four species noxious. Dominance were in order of Imperata cylindrica 〉Trifolium repens 〉Zoysia japonica 〉Centella asiatica 〉Festuca arundinacea. 4.

Hitherto several time of biological expedition to the jeju Island were carried out by Japenese and Korean scientists, however, none of scale insects were included in their reports. The anthors mainly in 1977 collected the scale insects in the Island, The results obtained revealed that the scale insects of the Island were consisted of 8 families, 29 genera.and 36 species of which the following 11 species are new to Korea. 1. Crisicoccus matsumotoi (SHIRAIWA,1935) 2. Pulvinaria torreyae (TAKAHASHI,1956) 3. Lecanodiaspis takagii (HOWELL et KOSZTARAB,1972) 4. Abgrallaspis degenerata (LEONARDI,1896) 5. Aondiella taxus (LEONARDI,1895) 6. Aspidiella Phragmitis (TAKAHASHI,1931) 7. Aulacaspis distylii (TAKAHASHI.1955) 8. Chrysomphalus bifasciculatus (FERRIS,1938) 9. Kuwanaspis Psudoleucaspis (KUWANA,1902) 10. Metaspidiotus stauntoniae (TAKAHASHI,1933) 11. Asterococcus muratae (KUWANA,1907) Thorough investigations will undoubtedly increase the number of species existing in the Island.

A new method is proposed to estimate the ultimate bearing capacity of the eccentrically loaded strip footing by the upper bound of limit analysis in this paper. The failure mechanism used in the upper bound is obtained by the model test using the carbon rods. The propriety of proposed method is verified by the results of model test, Meyerhof and Saran methods. And the influences of the parameters-footing width, eccentricity, surcharge and so on0on the bearing capacity are also studied in this paper.

The study was conducted to investigate the resistance to storage disease of mandarin fruits during its preservation. Samples were collected from citrus orchards located in various parts of Che-ju island. A total of 360 fruits were stored for 18 weeks (from 22nd December 1979 to 2nd April 1980). The results obtained are summarized as follows: 1. Fruit rot percentages during preservation were higher in the early and final stages of storage. blue mold (Penicillum italicum WEHMER) and green mold (Penicilium digatatum SACCARDO) were observed in the early stages, and gray mold (Botrytis cinerea PERSOON) and black rot (Alternaria citri PIERCE et ELLIS) were found in the later stages of preservation. 2. A total of six pathogenic molds were observed to develop during storage, in the following order: gray mold (Botrytis cinrea PERSOON) black rot (Alternaria citri PIERCE et ELLIS), blue mold (Penicilium italicum WEHMER), green mold (Penicilium digitatum SACCARDO), phoma rot (Phoma citricarpa McALP) and stem-end rot (Diaporthe citri WOLF). 3. The sugar content of the fruit decreased slightly during storage, this decrease did not result from the length of storage or location of origin. The acid content of fruit decreased in storage, but this decrease was not related to place of origin. A negative correlation existed between acid content and rate of fruit rot.

As recognizing the numerous advantages of interlocking block pavement for driveways, the use of block pavement for a wide range of applications has rapidly been increased in world wide. Each country presents the national standard for design considering circumstance, traffic volume and soil condition. The national specification for interlocking block pavement in this country is presented only for sidewalks and light roadways. Consequently, as increasing the use of block pavement, the national specification for heavy vehicle is also necessary. The structural pavement designs based on the national standards presented by Australia, German, Japan, USA and Great Britain, were examined in this study. Through the comparision study, an appropriate specification of interlocking block pavement for heavy vehicle roadways is proposed.

1) This was a comparative experiment on the efficacy of Sufanicotine and phosvel in orange orchards. Injury done insects to fruit trees occurs more frequently in Summer and Autumn sprigs, and these chemicals are more powerful repellents than usual insecticides. Chemicals Therefore, were sprayed continually at intervals of 7 days from Spring to Autumn and efficacy of Chemicals were compared by the number of injured leaves on Summer sprigs. 2) Efficacy of phosvel was more excellent than that of Sulfanicotine.

The purpose of this paper is to study the behavior of vertical anchor plate in cohesive soils. The model tests for the Kaolinite were conducted to define the ultimate holding capacity and the load-displacement relationship of a vertical anchor plate. In general, the ultimate holding capacity is expressed in terms of a non-dimensional breakout factor (Fc=Pu/(Cu·A)). As the results of this study, the followings can be determined. The breakout factor increases with an embedment depth ration(H/h) up to a maximum value and then remains a constant. The maximum value is called the critical embedment depth ratio which can be distinguished into the type of a vertical anchor plate. From these experiments, the ratio of about 7∼8 was determined. The holding capacity and the breakout factor from the model tests were also compared to the results of the theoretical methods. For a shallow anchor plate, the results of tests are shown a good agreement with those of the theoretical methods. For an anchor plate located at deeper than the critical embedment depth ratio, the values determined from this tests are shown smaller than those of the theoretical methods. It can be concluded that the results of theoretical methods overestimate the experimental those. A nondimensional load-displacement relationship is presented in the forms of a hyperbola and compared with the result of Das & Seeley method. And the new hyperbola constants is proposed.

The experiment was conducted to study the control of one of the major pests, the citrus red mite, Panonycbus citri with new acaricides. Although selection of effective acricides is the key to the control of citrus red mite, repeated application with the same chemical should be avoided because of the problem of chemical resistance. Among the chemical used "Torque" and "Prictran" gave the most effective control. Slight phytotoxic symptoms were observed on the young leaves with "Prictran" application.

The results of investigation, analysis and repair methods of the rainstorm induced landslides in the Seongeo Campus, Keimyung University on April 1997, is represented in this paper. Sedimentary rocks in Taegu area have a nonhomogeneous and anisotropic characteristics. Their physical and mechanical properties are very different to the angles of bedding planes. And if shale and mudstone are slightly weathered, the phenomenon of slaking and swelling is very remarkably appeared. The shear strength parameters are determined from the back analysis, the field investigation and the experimental tests, In order to increase the factor of safety, stabilizing pile method, rock anchor method, shoctcrete, and rock bolt are recommended. After application of those reinforcement methods under saturated condition in numerical analysis, the factor o9f safety is increased from 0.89∼1.45 to 1.26∼2.20.
