  • Powdery mildew diseases previously unrecorded in Korea were noticed on four species of ornamental trees. Field observations on each disease were described and the causal fungi were identified. Powdery mildew of Symplocos chinensis for. pilosa was found to occur mildly, especially on plants growing in shade. The causal fungus was identified as Microsphaera nomurae U. Braun. Cornus florida was found to be infected with Microsphaera pulchra Cooke & Peck and supposed to be epidemic in nursery. Powdery mildew of Malus baccata occurred on young leaves and herbaceous stems in nursery. The causal fungus was classified as Podosphaera leucotricha (Ellis & Everh.) Salmon. Powdery mildew of Ulmus macrocarpa was found to occur in autumn and severe on young shoots. Uncinula kenjiana Homma was identified as the causal fungus.

  • The design of a ground anchor wall calculating the design anchor force and anchored walls depends primarily on the earth pressure acting on anchored w deflection of the wall, the wall stiffness, distribution exists for anchored walls. In the apparent earth pressure envelope design of anchored walls. In this study, full scale anchored w pressure distribution was obtained from function. Earth pressures obtained from pressure and with the apparent earth pre the anchored wall in sand. It is conclude is appropriate for the anchored wall design.

  • Through a floral study and resource investigation of Korean mushrooms during the year 1993, five species of Agaricales, Pseudoclitocybe cyathiformis (Bull.: Fr.) Sing.; Pholiota brunnescens A.H. Smith & K. Hesler; Coprinus angulatus Peck; Rhodophyllus bisporus Hongo; Suillus viscidipes Hongo and one form of Gasteromycetes, Lysurus mokusin (L.: Pers.) Fr.f. sinensis (Lloyd) Kobayashi, were found and described new to Korean flora. Pseudoclitocybe is described as an unrecorded genus to Korea. The color names cited are from Kornerup & Wanscher's Methuen Handbook of Colour (1984). All the specimens are deposited in the RDAGB's and ASIK's herbarium.

  • To investigate the fungal diversity in Mt. Paekwoon, higher fungi were collected in July, 1991 from the two locations of Seoul National University Forests in Kwangyang-gun, Chonnam Province. A total of 137 fungal species were collected and classified. Following six species were identified as new species unrecorded in Korea. Their morphological and taxonomic features including microscopic characteristics of spores and cystidia were also reported in this paper. Marasmius pulcherripes Peck ; Agaricus purpurellus(Moller) Moller ; Coprinus echinosporus Buller ; Xerocomus nigromaculatus Hongo ; Boletellus shichianus(Teng & Ling) Teng ; Russula kansaiensis Hongo.

  • The tejocote (Crataegus spp.) is a tree considered to be native to Mexico. The aim of this study was to identify the causal agent of tejocote rust in the State of Puebla. Tejocote fruits were sampled in 2012 and 2013. The fungus was studied morphologically using light and scanning electron microscopy and molecularly using phylogenetic analysis of 18S and 28S rDNA genes. The fungus was identified as Gymnosporangium clavipes on tejocote fruits. To our knowledge, this is the first confirmed report of Gymnosporangium clavipes Cooke & Peck affecting Crataegus mexicana var. Chapeado and C. gracilior in Puebla Mexico.

  • Several higher fungi were collected at Andong during the summer and fall of 1976. About 100 higher fungi were collected at Mt: Sobaek and Youngju during the same period in 1978. These higher fungi were identified. As the results, Macrocystidia proved to be new genus in Korea. And the following are also newly-found species in Korea: Hygrocybe turunda (Fr.) Karst., Hygrophorus lucorum Kalchbr., Macrocystidia cucumis (Fr.) Heim var. latifolia (Lange) Imazeki et Hongo, Agaricus subrufescens Peck, Psathyrella hydrophila (Bull. ex Fr.) A.H. Smith, Stropharia rugosannulata Farlow f. lutea Hongo, Inocybe bresadolae Mass., Inocybe multicoronata A.H. Smith, Russula farinihes Romell and Lactarius sakamotoi Imai.

  • The governing design point of shallow foundation is not its bearing capacity but its settlemen and N-value by the SPT is one of the key parameters for settlement estimation. However, if the N-value is more than 50/30, such as 50/10 or 50/20, the N-vlaues are not blow count of 30cm depth penetration. In these cases, the estimated settlements have big difference with the measured values because the applied maximum N value for the settlement estimation is 50. Therefore, in this study, the modified method for N-value estimation is suggested. The settlements by four methods, which are based on Elastic Theory with application of modified N-value, are compared with the Origina Plate Load Test data. The same comparision was carried out with another seven Empirical Methods. The result of this study showed that the error range of settlement is decreased from 260.4~2136.5% to 20.3~272.7%. Among four methods which are based on Elastic Theory, the original method by Elastic Theory is the most accurate with the application of modified N-value. Among Empirical Methods, Terzaghi-Peck's(1948, 1967) modified method 1 is the most accurate with the application of modified N-value. The differences between the original method by Elastic Theory and Terzaghi-Peck's(1948, 1967) modified method 1 are neglectable.

  • In this paper as a univesal Banach space of the separable Banach spaces we investigate the complemented Banach subspaces of $_wL_{\hat {I}}$. Also, using Peck's theorem and the properties of the envelope norm of $_wL_{\hat {I}}$ we will find a canonical basis of $l_1^n, l_\infty^n$ for each n.

  • In this paper, comparison of the observed and the predicted ground deformations due to the construction of road embankment with peck drain near the construction site was made. Measurement of the ground deformation at the gasoline stand due to the construction of road embankment was made and it was compared with the predicted deformation results of Finite Element Method analysis made with Elasto-plastic and Elastic visco-plastic models. A well agreement was obtained between the measured and predicted ground deformations.
