This paper presents a miniaturized circularly-polarized antenna based on four meandered monopoles. The proposed antenna is a dual-substrate type, where four meandered monopoles printed on the upper substrate are fed by a series feed network on the lower substrate. Two substrates are connected by a metal post enclosed by a teflon cylinder. The antenna miniaturization is realized by highly meandering monopole arms and transmission lines of the feed network with the size reduction of 78%. Short-circuit stubs for impedance matching of meandered monopoles are employed on the lower substrate for structural simplicity. The fabricated antenna has a dimension of 0.11×0.11×0.022 λ0, -1.9dBic gain, 1.4dB axial ratio, and 11.5dB front-to-back ratio at 915MHz.

Most modern people has a mobile phone, a PC and USB memory sticks for academic and business data storages. In the data of USB can not confirm without a PC, People face problems when they have to confirm or move quickly the files. To solve this problem we will develop small board for conjunction with a mobile phone and Windows Mobile Application for viewable USB system on screen and transfer files to another USB. So we're going to build system whenever and wherever you want see or transfer the files.

1979年度 本大學 農科大學에서 들깨의 品種改良 및 育成을 위하여 全國 109個 地域 在來系統 蒐 集種中에서 比較的 優秀한 20個 系統을 選拔하여 1980年度에 계속 사업으로 實施한 本實驗에서 몇가지 結果가 있었기에 이를 報告하는 바이다. 1. 本實驗에서 收量은 大邱種보다 제천-3070-28이 35.9%, 연기-4120-35가 51.5%, 남제주--7010-67이 53.7%, 문경-8090-71이 69.1%, 하동-9220-97이 44.2% 가량의 增收를 하였다. 2. 各 形質間의 相關關係는 收量과 莖直徑, 有效分枝數間에는 正의 相關關係가 認定되었고 1000粒重에 있어서는 花房數 및 油脂含量間에 否의 경향을 나타내었다. 3. 油脂含量에 있어서는 갈색계통인 금능-80 50-69가 49.6%, 제천-3070-28이 47.4%, 성주-8130-72가 47.7%로 높았고 白色系統은 比較的 油脂含量이 낮았다. 4. 多重不飽和 脂肪酸에 있어서도 갈색계통은 53.4%인데 비하여 白色系統은 46% 정도로 낮았다. 5. 들깨 잎에는 칼슘함량에 있어선 연기-2060-17이 284mg/100g으로 가장 높았고 나주-60 80-49가 241.4mg/100g으로 다음 이었다. 그리고 마그네슘은 성주-1830-72가 77.5mg/100g으로 가장 높았고 蛋白質含量은 남해-932 0-102, 금능-8050-69가 5.5g/100g 以上으로 높은 數値를 나타내었다. The experiment was carried out continualy from 1979 for the Perilla, breeding and variety improvement of excellent lines selected from 109 local species, and the results obtained were summarized as fellow: 1. The increasing ratio of yield per 10a were 35.9% in Jecheon-3070-28 lines, 51.5% in Yeongi-8090-71, 53.7% in Namje ju-70l0-67, 69.1% in Mungyeong-8090-71 and 44.2% in Hadong-9220-97 as compared with the yield amount of Daegu. 2. Statistically positive correlation were convinced between yields and plant length, stem diameter, and number of effective valid branches. 3. In percentage of oil composition, Geumnung-8050-69 was 49.6%, Jecheon-3070-28 was 47.4%, Seong ju-8130-72 was 47.7%, and the oil contents of these brown seed coat lines were considered to be comperatively higher than those white seed coat lines. 4. Contents of ploy-unsaturated fatty acid was 53% in brown seed coat lines, on the other hand, that of white seed coat lines was about 43.9%. 5. In calcium contents of perilla leaf, the amounts of 284.7mg in Yanggu-2060-17 was the highest and Na ju-6080-49 (241.4mg) was the next, Seongju-8130-72(77.5mg) was highest in magnesium composition, and the protein content in Namhae-9320-102, and Geumnung-8050-69 were more than 5.5g.

In order to determine the adequate value of the date of seeding bed and day of transplanting under the supremely late seasonal culture of rice. 3??factorial experiment was under taken, and the result obtained were as follows: 1. The highest yields on grain were revealed at the plot of 40days per seedling bed. 2. The heightest yields on grain were also convinced at the plat of earlier date of transplanting. 3. yields of 329kg/10a at the transplanting date on August 4th were obtained under the supremely late seasonal culture of rice. 4. Extermely limited time transplanting date were August 4th in Southren sea-side.
