솔껍질깍지벌레는 우리나라 곰솔림의 주요한 해충의 하나이다. 본 연구는 우리나라에서 솔껍질깍지벌레의 분포를 알아보기 위하여 7개도 3개 광역시, 91개 시군구, 686 읍면동의 해송림에서 2010년 밀도를 조사하였다. 5개도 2개 광역시에서 솔껍질깍지벌레가 서식하고 있었는데 시군구별로는 조사대상의 64.8%인 59개 시군구에서 서식이 확인되었다. 솔껍질깍지벌레의 분포는 남해안 전역과 동해안의 포항, 서해안의 충남 보령지역까지 분포하였다. 충북과 대전광역시 및 제주도에서는 솔껍질깍지벌레의 분포가 확인되지 않았다. 부산지역은 16곳의 모든 구에서 솔껍질깍지벌레가 분포하였고, 시군 단위에서는 전남 해남군의 솔껍질깍지벌레 평균밀도가 1.713마리/0.785 $cm^2$로 가장 높았으며 읍면동 단위에서는 해남군 송지면이 6.36마리/0.785 $cm^2$로 가장 높았다. 곰솔 가지 내의 솔껍질깍지벌레 밀도와 솔껍질깍지벌레가 서식하고 있는 빈도와는 높은 상관관계가 있었다(상관계수=0.89). The black pine bast scale, $Masucoccus$ $thunbergianae$ (Hemiptera: Margarodidae), is a serious pest of the Japanese black pine, $Pinus$ $thunbergii$, in Korea. The distribution of the black pine bast scale was examined, looking overall at 686 towns (eup), townships (myeon) or neighborhoods (dong). There were Japanese black pine ($Pinus$ $thunbergii$) forests in 91 cities, counties (gun) and borough (gu), in seven provinces and three metropolitan cities during 2010. Black pine bast scale were found in 64.8% of cities or counties or borough (59) in 7 provinces and 3 metropolitan cities, and were distributed in all South Costal regions, Pohang in East Costal region and Boryeong in West Costal region. Chungcheongbukdo, Daejeon and Jeju did not have black pine bast scale. All the gu regions in Busan had black pine bast scale, of which the area with the highest prevalence was Haenam in Jeollanamdo (1.713 crawlers/0.785 $cm^2$). Songji-myeon had the highest occurrence rate (6.36 crawlers/0.785 $cm^2$) from the towns, township and dong. The density of black pine bast scale in twigs was highly correlated with percentage of the sample with scale (Correlation coefficacy=0.89).

Quantitative determination of diarylheptanoids (oregonin and hirsutanonol), which were characteristic components of Alnus spp. has been conducted by High Performance Liquid Chromatography. The HPLC analysis was carried out using an YMC J'sphere ODS-H80 column [150×4.6mm, S-4μm. 80A(particle)] and a combination of acetonitrile and H2O was used as mobile phase in gradient solvent system. The results showed differnce in the species (Alnus japonica, A hirsuta and A. hirsuta var. sibirica)

To inrestigate the biochemical characteristics of continuous cropping soil Planted tomato plant, chemical properties, the types of humus, microorganisms'phases, and enzymes activities are examined and the results are summarized as fellows. 1) The chemical properties of the sample soil did not correspond with the continueuse cropping years. Maybe the sample soil is not suited for vegetables because the chemical properties of the soil were not good. 2) The content of humus did net have regular changes, either, But the content of humic acid was decreased with continuous cropping rearm. Fulvic acid was relatively increased with them. 3) Precipitation ratio (PQ) and FA/TC were increased with continuous cropping years, but HA/TC and the content of total carbon were decreased with them. 4) The number of bacteria, fungi, phytophthora, and prthium was increased with cropping years except actinomycetes and fusarium. 5) B/F ratio was decreased with cropping years, and it seemed that the sample soil was changed gradually into the fungi-type. 6) The activities of β-glucosidase, protease, and polygalacturonase were not shown the regular changes with cropping years.

The proper resource allocation is a very important topic in power system problems, especially in operation and planning. One of such problems is optimal maintenance in operation and planning. The least cost should be the subject to be pursued in this study. A simulation model of a probablistic operation which is called cumulant method, is applied to the problem of optimal maintenance scheduling. A new technique called time axis shift method is developed. This method is similar to dynamic programming successive approximation.

The deposition amounts of Ferric that are naturally originated elements from earth crust. The rate was 14,993㎎/㎡ day at the rang yellow sand season, which was 20 times higher than at the ordinary times. Artifical earth crust element Cr were lower than the amount yellow sand an increase. Naturally originated elements origination, movment channel and mutual be close the correlations of elements each other and were lower than in artificially originated elements. Deposition amount of chang were higher before yellow sand, lower before yellow sand of origination, time were inverse proportion. The average concentration of liquefactive metals high, compare heavy matal and numerous of deposition amount. A1so gain liquefactive matal were rescattering numerous on account of little mass deduction.

This paper describes on the results of 1:400 geometrical laboratory modeling of wind-induced point pressure on the membrane roof structure of Stadium with variable roof slopes. The wind flow for flat ground surface was simulated in a boundary wind tunnel at Kumoh National Institute of Technology. The roof slope of membrane structure changed into 5 types. The locations of wind pressures taps are distributed on the same upper and lower part of membrane roof. The resultant wind pressure for each measurement points are analysed on 2 categories. One is acting on upper direction, the other is lower direction. The results showed that in the case of upper direction the changes of wind pressures on the membrane roof are not dominant in regard to changing roof slope, but in lower direction wind pressures are increased at the rear part of roof with changing roof slopes.

This paper shows the characteristics of sparkover discharge in flowing air ranging from 0[m/s] to 30[m/s] under the non-uniform fields gap. The quantities of ozone generation are measured for various electrodes forms (needle-needle electrode, needle-rod electrode, rod-rod electrode) on the constant Reynolds Number(Re). Some principal results of this study are as follows. The discharge pattern can be controlled by adjusting the Reynolds number. The quantities of ozone generation at each corona forms are described as follows glow corona(g.c)<brush corona(b.c)<streamer corona(s.c). The quantities of ozone generation rapidly increases to 2[cm] and decreased over 2.5[cm] in case of various electrode gaps 1, 1.5, 2 and 2.5[cm] with constant Re.

Recently, Phase Transfer Catalyzed Organic Synthesis is studied intensely. The Reactions of benzyl chloride with various alcohols (Et, n-Pr, iso-Pr, n-Bu, iso-Bu, sec-Bu, tet-Bu, Ph, Bz-OH) were investigated under Phase Trasfer Catalysis in this research. Benzyltrietylammonium chloride(B.T.E.A.C), dodecyltrietylammonium bromide(L.T.E.A.B) and tetrabutylammonium chloride(T.B.A.C) were used as Phase Transfer Catalyst. The Optimum Conditions between benzyl chloride and varios alcohols were studied in the presence of T.B.A.C which proved to be most effective among catalysts tested. Optimized conditions were as following. The molar ratio between benzyl chloride and tertiary butanol was 1:3. The amount of catalyst was 1.08mmol. And the amount of 50% NaOH aqueous solution was 7g. Under optimized conditions, it has been observed that benzyltet-alkyl ether, benzylphenyl ether and dibenzyl ether can be obtained in good yield over 80%, benzyliso-alkyl ether in about 50%, benzyln-alkyl ether only in less than 20%. The tendency of yield in various alcohols was increased Et<Pr<Bu<Bz<Ph-OH. And the tendency of yield in isomeric alcohols was increased primary<secondary<tertiary alcohol.
