The purpose of this study was carried out an epidemiological survey on the prevalence rate of the canine heartworms in Seoul City and the districts of Pa-Ju, Seong-Nam and Po-Chon in Kyonggi province of Korea from September 1994 to the end of September 1995. The blood samples from 292 male and 193 female dogs (pet, 363 ; fighting dogs, 60 ; working dogs, 62) were examined for the adult heartworms cuticle antibodies using the enzyme-linked immunosorbent assay (ELSA) kits. The test was designed to detect the antibodies of the host against the specific cuticle antigens produced with the adult heartworms.

오이 連作土壤의 오이生育과 微生物相에 미치는 珪酸의 影響 : 제2보 : 微生物相에 미치는 珪酸의 影響 Ⅱ. Effects of the Silicate on the Microflora

成基英,金廣植 全南大學校 農漁村開發硏究所 1988 農業科學技術硏究 Vol.23 No.-

오이 連作土壤의 微生物相에 미치는 珪酸의 影響을 檢討하기 위해 連作土壤에 湛水處理와 珪酸을 施用하여 土壤의 化學的 變化 및 微生物相의 變化 등을 調査分析한 結果를 要約하면 다음과 같다. 1. 供試土壤의 化學性을 보면 모든 土壤이 pH6.3∼6.8로서 오이 生育에 적당한 土壤反應을 보였으며 2年 連作土壤의 EC가 0.88mmho/cm로 監類集積에 의한 障害가 예상된다. 2年 連作土壤에 有效燐酸과 有效珪酸의 含量 및 一般性分의 含量이 많았다. 2. 오이 栽培한 連作土壤의 化學性의 變化는 珪酸施用區가 pH7.0정도였으며 2年 連作土壤의 湛水處理와 珪酸施用區에서는 EC가 0.1∼0.18mmho/cm로 減少했다. 2年 連作土壤의 珪酸400kg/10a施用區에서는 播種後 35日에 有效燐酸이 142ppm 이 되었다. 또한 2年 連作土壤의 珪酸 40kg/10a 施用區에서는 Ca/Mg 2.9 Ca/K5.2 Mg/K 1.7로서 기준치와 유사한 경향이었다. 湛水處理區에서는 Ca/Mg 1.8∼1.6, Ca/K 2∼8, Mg/K 1.5∼1.6으로서 監基의 均衡維持가 요망되며 一般性分이 낮은 경향이므로 施肥面에서 유의해야 할 것 같다. 有效珪酸은 珪酸施用區에서 500ppm以上으로 增加했으며 播種後 60日에 감소하는 경향을 보였다. 3. 放射狀菌은 湛水處理와 珪酸 施用區에서 10??에서 10??으로 增加했으며 Fusarum 屬菌은 10??으로 增加경향이 보이지 않았다. 絲狀菌은 非 連作土壤보다 連作土壤에서 그 數가 10??으로 많고 珪酸 400kg/10a 施用區에서는 增加 경향이 없었다. 한편 細菌은 珪酸施用區에서 10??으로 增加하였다. 4. 非連作土壤의 栽培前의 B/F直은 50이었는데 栽培後 35日에 43.8, 60日에는 42로 낮아지는 경향이며 2年 連作土壤의 珪酸 施用區에서는 26.8에서 35日에는 80으로 60日에는 187로 增加했다. 또 3年 連作土壤의 對照區는 播種後 점차 감소되었다. 亞窒酸化菌은 10??으로 湛水處理에 의해 增加했으며 珪酸 200kg/10a 施用區에서 또한 增加했다. 암모니아 酸化는 10³∼ 10⁴이고 處理間에 뚜렷한 變化가 없었으며 脫窒菌은 10³∼ 10??였으며 播種後 10⁴∼ 10?? 으로 增加했다. An attempt has been made to establish an effective way of eliminating the harmful effects due to continuous cropping of cucumber(cucurbitaceae) in the same soil. Cucumber plants were cultured in pots with silicate fertilizer added in pots water logged before planted. The change of soil chemical properties and the transient change of the number of microflora were determined. From these experiments some of the results obtained are summarized as follows. The harmful effect of nutritional accumulation in soil of vinyl houses can be prevented by water logging because in water logging accumulated chemical components in the soil are leached. As for the changes in the chemical properties of sample soil in silicate treated soil compared to silicate non treated soil available silicate(500-750ppm) and available P₂O??,(140-2 10ppm) increased. In silicate treated soil in 3 year continuous cropping soil the pH is between 6-7 and the EC is lowered and this is suitable for cucumber planting. The number of fungi, actinomycetes and bacteria show a tendency to increase with the elapse of growing days(from 10⁴ to 10?? : 10??-10??, 10??-10??) respectively. In the silicate added soil the number of fusarium and fungi notably decrease . In the 3 year continuous cropping soil the value of B/F (21.2-7.8-21.8) compared to that of 1 year cropping soil (26.8-53.0-26.0)decreased but in the silicate added soil of 2 year continuous cropping soil the value of. B /F( 200kg/10a: 26.8-45.0-88.0, 400kg /l0a: 26.8-80.0-187.0) increased.

In this paper, we propose an encoding algorithm for micro-operations which minimizes output transactions of control store. The transition rates between two micro-operations are computed based on the instruction usage frequency and the symbolic micro-codes of each instruction. Then, codes are assigned to micro-operations such that the Hamming distance of codes between micro-operations with higher transition rates is smaller. Experimental results on a x86 real mode symbolic micro-code set show that the proposed algorithm reduces the switching activity by 32% with only 6% area increase compared to the results of NOVA input encoding.

This paper deals with designing the linear power amplifier using MESFET and Schottky diode. The power amplifier is designed to be ensure 3-W linear output using MESFET, and made up of 3-stage class-AB amplifiers in cascade. By choosing the final stage as the balanced structure, the output linearity is enhanced. The balanced structure of amplifier is composed of the Wilkinson power divider and combiner. In the designed 3-stage amplifier, when the input power is lower than -5dBm, power gain is 38dB. And it rapidly decreases as the input power increases larger than -5dBm. Therefore, to compensate for decreasing the gain, pre-distorter circuit is inserted in front of 3-stage amplifier. The pre-distorter is implemented using parallel Schottky diode. The optimized linear power amplifier is composed of these pre-distorter and 3-stage power amplifier. As a result, when the maximum input power is 9dBm, the 1-dB gain compression point of linear power amplifier, P1dB, is 37.61dBm

The existing daylight analysis systems using computers are system independent, which means each system constructs own data for the daylight analysis in a separate way, and the data and information exchange between systems is not possible. If a single case of daylight analysis is compared, analyzed and evaluated in different systems, each system will repeat unnecessary process of producing, constructing and analyzing the same data. This causes a waste of resources and expenses in these works, and interferes with accurate, clear comparison and evaluation of the results owing to the possible errors and mistakes in the process of producing and constructing the data needed in each systems. Accordingly, this study aimed 1) to develop "Common Data Model & Analysis Module" for Daylight Analysis in order to share, exchange, analyze data between various systems that are operated independently, Also 2) aimed to consider the future extensibility of those applications on the web. And 3) aimed to propose this "Common Data Model & Analysis Module" as a prototype & protocol standard for daylight analysis system.

Recently, a wide variety of maladaptation, such as school refusal or mental disorder, has remarkably increased in high school students in Korea and Japan. The increase of stressful events which students experience in their school life is regarded as one of the causes of this phenomenon. The previous study which attempted to clarify the school stress process(Shimada et al., 1993, 1995, 1996) developed the school stress(Emotional Response, Psychological Response, School Maladjustment, Irrational Beliefs Scale) scales for high school students to assess both the frequency and the averseness of events which students encounter in their daily school life. 659 Korean and 211 Japanese high school students completed the stress process scale. The main results were as follows. (a) Korean students evaluated the Emotional Response Scale at a higher level than Japanese did. (b) Korean students evaluated all the Psychological Response Scales at a higher level than Japanese did. (c) Japanese student evaluated School Maladjustment scales (study evaluation, club activities evaluation) at a higher than Koreans did. But at the school evaluation scale is the response diametrically opposed. (d) Korean students evaluated all the Irrational Beliefs Scales than Japanese did. In summary, Korean students felt the events in high school were more stressful than Japanese did.

This study was designed to research the clinical efficacy and tolerance of Diclofenac sodium, a potent inhibitor of prosta-glandin synthetase. Total 53 cases of painful condition in orthopaedic field were treated with Diclofenac sodium, available for intramuscular injection, in department of orthopaedic surgery of Chungnam National University Hospital from Nov. , 1986 to Jan. , 1987. Among 53 cases of painful condition, The most common condition was rheumatoid arthritis and osteoarthritis (33cases; 60. 3%), followed by sprain and strain(llcases; 20. 8%), postoperative state(7cases; 13.2%), and others(3cases 5.7%). There was no predilection in age and sex distribution. At thirty minutes after the injection, 46/53patients treated with Diclofenac sodium had complete 31(58.5%) or partial 15(28..3%) relief of pain. Side effects were mild and transient. It is concluded that intramuscular injection of Diclofenac sodium is effective in treatment of pain due to operative intervention & various disease in orthopaedic field.
