The main purpose of his paper is three-fold: First, we summarize the arguments that by-phrase in English passives is an adjunct, not an optional complement and analyse the passive constructions on the basis of hypotheses of Bouma, Malouf & Sag(1998). That is, the prepositional phrase, by-phrase, has been treated as an adjunct in previous studies so far: Kiparsky(1987), Grimshaw(1990),Wechsler(1995) and Jo & Chung(2000). Second, we point out that the dative particle -ey/eykey shows that it is a postposition rether than a morphological case-marker. We use the various tests to see if -ey/eykey is a case or a postposition. Third, on the basis of Urushibara(1991), O'Grady(1991) and Chung(1995), we argue the -ey/eykey in Korean passives should not be a complement but an adjunt. Empirically, we have also demostrated that our argument enable us to analyse further Korean passive types in Korean.(Chosun University)

It is generally recognized that the income of farm households, most of them are of small scale in case of LDCs, will be able to increase if the industrial sector develops so as to take economic advantage of farm land. This paper aims to suggest some policy implications to increase employment and income of farm factories located in agricultural area. Thus are analyzed how the sector can contribute to the increase of those farm households of small scale, what obstacles against them are, and what policies we can use to remove them out of the area. A sample was selected from four economic areas-Non-san, Naju, Sungju and Miryang. In each economic area sectors were divided into two; one which lies adjacent to the factories in farm and the other does not. From each sector two villages were sampled and from each village were sampled and from each village were selected 18 farm households. Thus the total number of them amounted 289. According to the analysis: ⅰ) the ratio of employment was higher in the sector adjacent to farm land factories, than the other sector. ⅱ) the distribution of all the employed was concentrated on the small scale farm household. ⅲ) most of the employed were younger people-teenagers and 20ths. ⅳ) the household income of the employed was increased. So, it is proved that the farm-factories contribute to increasing farm household income and the increase of the increase of the opportunities of employment of the idle people in agricultural area, especially of small-scale farm household members. Besides these results, some problems were discovered from this analysis; ⅰ) these factories pushed out polution, ⅱ) the wage in this was increased because of the increasing employment in the factories. ⅲ) the production of agricultural products, particularly rise, was declined because of poor mechanization. ⅳ) the scale of the factories was too small to make a sufficient profit to the employers. ⅴ) the skills of the peasants was not so high that the employers are willing to employ them in their factories. From these results, I suggest some following policies. Firstly, the conditions of location of the farm land factories must be improved in order to employ more peasants. Secondly, the vocational education of farm laborers must be strengthened. Thirdly, those men and women should be promised to be employed by the factories who have finished the course of technical education.

Joint monitoring of yellow sand (YS) phenomena occurred from 1997 to 2000 was carried out. It was found that the YS in source regions occurred in any time during the year, while the severe dust storms occurred frequently from March to May after the spring thaw. Wind erosion occurred usually with wind greater than about 8 ms^-1 in the source region in any seasons. However, severe YS phenomenon found to occur with wind greater than 15 ms^-1 at least for 3 hours or more. In source regions, YS occurred over 60∼120 days per year. In Korea, YS was found to occur 8∼12 cases per year with 12-22 YS days. It was recorded that maximum concentrations of TSP were 989∼1396 ㎍ m^-3 with PM10 values of 861∼996 ㎍ m^-3 and with the lowest visibility of 1.4∼1.6km. In Mongolia, however, it was observed that the number of dusty days decreased due to the increase in rainy days.

The effect of temperature on transmembrane potential and contractile tension of the papillary muscle was investigated in the rabbits perfusing with bicarbonate buffered solution. Lowering of temperature from 36℃ to 24℃ decreased resting membrane potential from -88.5±1.1 to 71.0±3.4mV, increased overshoot potential from 16.1±0.5 to 23.2±0.7mV. Therefore, the action potential decreased slightly from 104.6±1.5 to 94.2±4.0mV. And duration of action potential increased from 123±1.0m sec at 36℃ to 345±5.1m sec at 24℃. Contractile tension increased consistently as temperature of bicarbonate-buffered solution lowered. The increment was due to prolongation of active state, not due to increase in dT/dt, resulting in prolongation of duration of contraction. The activation energies obtained from action potential duration and duration of contraction were 19.200 and 23.700 cal/m/degree.

The effects of drainage system on evapotranspiration and drainage flows are studied. Data from drainage field experiment at Castalia in North Central Branch, Ohio Agricultural Research and Development Center were used in this study. A water table management model, ADAPT(Agricultural Drainage and Pesticide Transport), which was developed by combining the GLEAMS and the subsurface drainage part of the DRAINMOD model with several modifications, was used to predict hydrologic components. The ET is very much affected by the presence of subsurface drainage system but not significantly affected by the surface drainage system. The combined surface and subsurface drainage system gives the largest total outflow values while the surface drainage system gives the smallest. Comparisons of model predicted and measured drainage values are in satisfactory agreements. The model predicted values are within the range of the variations of the observed replications in general. Based on this study, the ADAPT model can be used in designing water table management systems.

콘택트렌즈 보존 용기 유래 가시아메바 KA/L5주의 세포질 내에 존재하는 bacterial endosymbiont(내공생세균)를 투과전자현미경으로 관찰하여 확인하였다. 숙주인 가시아메바 KA/L5주는 형태학적으로 제2군에 속하였고, rDNA PCR-RFLP 결과 A. lugdunensis로 동정되었다. 미토콘드리아 DNA RFLP와 동위효소 분석상 이 충주는 국내 콘택트렌즈 보존용기에서 가장흔히 분리되는 type인 KA/Ll주, 국내 임상 분리주 중 하나인 KA/E2주, 내공생세균을 가지는 것으로 보고된 병원 냉각수 유래 KA/W4주 및 L3a주와 동일하거나 매우 유사한 성적을 보였다. 내공생세균은 약 1.38× 0.507㎛의 크기였고, 아메바 세포질 내에 불규칙하게 분포하고 있었으며. 그 표면에 아메바의 ribosome이 부착되어 있었다. 내공생세균을 둘러싼 lacunae나 막과 같은 구조는 관찰되지 않았다. Legionella 특이 primer를 이용한 효소중합반응(PCR)에서 내공생세균의 염색체 DNA는 증폭되지 않았다. A. lugdunensis의 우리말 이름을 담수가시아메바로 제안한다. Transmission electron microscopy of an Acanthamieba isolate (KA/L5) from a contact lens case revealed bacterial endosymbionts within cytoplasm of the amoebae, The Acanthamoeba isolate belonged to the morphological group II. Based on the polymerase chain reaction (PCR) - restriction fragment length Polymorphism (RFLP) of 18S ribosomal RNA coding DNA (rDNA), the Isolate was identified as A. lugdunensis. Strain typing by isoenzyme analysis using isoelectric focusing (IEF) and mitochondrial (Mt) DNA RFLP revealed that the isolate was closely related with KA/Ll , the most predominant type of isolates from contact lens storage cases, KA/E2, a clinical isolate, KA/W4, preciously reported to host endosymbionts, and L3a strains of A. lugdunensis. The endosymbionts were similar to those of KA/W4 In aspects that they were randomly distributed in both trophozoites and cysts, and were rod-shaped bacteria measuring approximately 1.38x 0.50㎛. But the number of endosymbionts per amoeba was significantly lower than that of KA/W4. They were neither limited by phagosomal membranes nor included In lacunae- like structure.

본 논문에서는 2.45GHz ISM 대역의 전력 제어시 추정 오차를 줄이기 위하여 콘덴서를 이용한 직접 결함 전력 검출기와 방향성 결합기에 의한 전력 검출기를 설계하여 전압 감도, 대역폭, 기판 크기 등의 특성을 비교. 분석하였다. 측정한 결과, 전압 감도는 입력 전력이 -50dBm 에서 -25dBm까지는 전압 감도가 거의 비슷하지만 -25dBm에서 -10dBm까지는 방향성 결합기에 의한 전력 검출기의 전압 감도가 최대 3.5㎶/㎼ 정도 우수하며, 대역폭은 방향성 결합기에 의한 전력 검출기가 콘덴서를 이용한 직접 결합 전력 검출기보다 63MHz 더 넓었다. 그러므로 전력 제어를 위한 검출기 선정시에 송신기의 출력 레벨이 -20dBm 이하인 경우는 특성이 비슷하므로 기판 크기를 줄이기 위해서는 콘덴서를 이용한 전력 검출기를 선정하는 것이 좋고, -20dBm 이상 또는 광대역의 경우는 전압 감도를 고려하여 방향성 결합기에 의한 전력 검출기를 선정하는 것이 추정 오차를 줄일 수 있다. In this paper, we designed the power detector with the capacitor to decrease the estimation error and directional coupler which are used in 2.45GHz ISM band, also compared and analyzed the characteristics of the power sensitivity to estimate the performance of detector, the bandwidth and the printed circuit board size. As the results, their voltage sensitivity is constant from -50dBm to -25dBm which is the input power, but the detector composed by the directional coupler is superior about 3㎶/㎼ than that by the single diode from -25dBm to -10dBm and its bandwidth is wider about 63MHz than the directional coupling power detector with the capacitor. Therefore when the output level of transmiter is below -20dBm, the power detector with the capacitor had better be selected as the detector for the power control to reduce the area because of the similar characteristics, and above -20dBm or in the wide band system, the estimation error can be eliminated by the selection of directional coupler considered the voltage sensitivity for the power detector.

From Jan. 1979 to June 1981 authors studied on the characteristics of fourty five newborn infants with non-hemolytic jaundice admitted in pediatric ward of Chung-Nam National University Hospital following phototherapy. The results were summarized as follow; 1. Incidence was male predominant with male to female ratio being 2. 5 to 1. 2. Wide variations of birth weights and gestational age were noted ranging of 1800 to 4350gm and 34 weeks with average of 2902.4gm and 39.96 weeks. 3. The level of total bilirubin in serum at admission was the most frequently encountered in 15.0 to 20.0 mg% and 30.1% in 20.1mg% and more group. 4. 35.6% of cases had jaundice less than 3 days while 64.4% more than 4 days before hospitalization. 5. The smaller the birth weight was, the higher the billirubin level and the number of cases noted. 6. The younger the gestational age was, the higher the bilirubin level and prematurity rate observed. 7. Decreasing tendency of the total bilirubin level by weight with phototherapy was remarkably high for the first 24 hour and diminished with time and the smaller the birth weight was, the more the decreasing rate of it demonstrate in all groups. 8. Decreasing tendency of the total bilirubin level by its severity with phototherapy was significantly high for the first 24 hours and with increasing bilirubin level and diminished with time in all groups.
