Various oxide films are commonly used as a sacrificial layer or etch mask in the fabrication of microelectromechanical systems (MEMS). Large residual strain of these oxide films cause the wafer to bow, which can have detrimental effects on photolithography and other ensuing processes. This paper investigates the residual strain of tetraethoxysilane (TEOS), low temperature oxide (LTO), 7wt% and lOwt% phosphosilicate glass (PSG). Euler beams and a bent-beam strain sensor are used to measure residual strain. A polysilicon layer is used as a sacrificial layer, which is selectively etched away by XeF_(2). First, the residual strain of as-deposited films is measured, which is quite large. These films are annealed at 500℃, 600℃, 700℃ and 800℃ for 1 hour and residual strain is measured. Then, the residual strain after annealing at the conditions for depositing a 2μm thick polysilicon at 585℃ and 625℃ are also measured. Our results show that the 7wt% PSG is best suited as the sacrificial layer for 2μm thick polysilicon processes.

딸기 ‘설향’ 품종에 대해 삽목 육묘의 조건을 확립하고자 삽수 채취용 모주 선택, 삽수의 적정 엽수 및 삽목 시기를 구명하였다. 삽수 채취는 육묘장 모주와 과실 수확 후 재배 식물체에서 채취하였고, 삽수의 엽수는 0, 1, 2장 그리고 삽목 시기는 6 월 4일부터 7월 9일까지 1주일 간격으로 하였다. 육묘장 삽수와 재배 식물체 삽수의 최종 생존율은 각각 99.5%, 98.7%로높았으며, 유의적인 차이는 없었다. 근수는 육묘장 삽수에서3.1개 많았고, 관부와 잎의 생육은 차이가 없었다. 과실 수량은 육묘장 삽수와 재배 식물체 삽수에서 각각 419.2g, 428.4g 이었지만 유의적인 차이는 없었다. 삽수의 엽수별 생존율은엽수 1, 2장에서 각각 98.1%, 98.3%로 높았고, 0장은 25.3% 로 현저히 낮았다. 근수는 엽수 1, 2장에서 각각 26.0개, 26.3 개로 엽수 0장의 23.5개에 비해 많았다. 관부와 엽의 생육에서는 엽수에 따른 유의적인 차이가 없었다. 과실 수량은 엽수 1, 2장에서 각각 424.4g, 421.5g으로, 0장 396.7g 보다 많았다. 삽목 시기에 따른 삽목 후 생존율은 97.2% 이상으로 높았으며, 처리 간의 유의적인 차이는 없었다. 묘의 지하부와 지상부그리고 관부의 생육은 6월 4일과 11일 삽목에서 가장 좋았다. 과실 수량은 6월 4일, 6월 11일 삽목에서 각각 433.3g, 426.4g 으로 가장 많았으며, 삽목 시기가 가장 늦었던 7월 9일 삽목에서는 384.5g으로 적었다. 딸기 삽목용 삽수 재료는 육묘장 삽수와 과실 수확을 마친 재배 식물체 삽수 모두 가능하였고, 삽수의 적정 엽수는 최소 1장 이상 그리고 경남 지역의 삽목 시기는 6월 4일-11일이 적합하였다. This study was conducted to investigate optimal conditions for cutting propagation of the strawberry cultivar “Sulhyang” through the collection methods of cuttings (runners tips), leaf number of cuttings, and cutting time. Cuttings were collected from the mother plant in the nursery bed (MP) and plants after fruit harvest (HP); the leaf number of cuttings was 0, 1, and 2, and the cutting time was at one-week intervals from June 4 to July 9. The survival rates for MP and HP cuttings were notably high, reaching 99.5% and 98.7%, respectively, but no significant difference was found. The number of roots were higher in MP cuttings, and there was no significant difference in crown and leaf growth. The fruit yields were 419.2 and 428.4 g, for MP and HP cuttings, respectively. The survival rates according to leaf number of cuttings were 98.1% and 98.3% for 1 and 2 remaining leaves, respectively, and remarkably lower at 25.3% for no remaining leaves. The root numbers were 26.0 and 26.3 for 1 and 2 remaining leaves, respectively, compared with 23.5 for no remaining leaves, with no significant differences in crown and leaf growth. The fruit yields were 424.4 and 421.5 g for 1 and 2 remaining leaves, respectively, and 396.7 g for no remaining leaves. The survival rates according to cutting time was over 97.2% in all cutting time without any difference in each treatment. The root, shoot, and crown of the nursery plant before planting showed the best growth in the cuttings on June 4 and 11, resulting in the highest fruit yields of 433.3 and 426.4 g, respectively, with the lowest yields at 384.5 g for cutting time on July 9. Both MP and HP materials proved suitable for strawberry cuttings. The optimal leaf number for cuttings was at least 1, and the optimal cutting time in Gyeongnam area was evaluated as around June 4-11.

4개의 Post 형태 기생소자를 추가한 광대역 슬리브 모노폴 안테나 설계

이상우,김갑기,Lee, Sang-Woo,Kim, Kab-Ki 한국정보통신학회 2007 한국정보통신학회논문지 Vol.11 No.1

본 논문은 Top-loading한 슬리브 모노폴에 4개의 Post 형태 기생소자를 추가함으로써, 기존의 상용 이동통신 시스템의 주파수를 하나로 통합 할 수 있는 소형이면서, 광대역 특성을 갖는 모노폴 안테나를 설계 및 제작하였다. 각 소자의 Parameter 변화에 따른 반사손실 특성을 관찰하였고, 제안된 안테나의 광대역 특성을 확인하기 위하여 PCS, W-CDMA, WiBro, W-LAN, S-DMB 대역에서의 복사 특성을 살펴보았다. 제안된 안테나는 수평면내 무지향성, 수직면내 8자형의 지향성을 가지며 $1.67{\sim}3.55\;GHz$ 주파수 대역($B/W{\fallingdotsep}72%$) 에서 Return loss$Return\;loss{\leq}-10\;dB$의 양호한 반사손실과 $1.14{\sim}3.66\;dBi$의 이득을 얻을 수 있었다. In this paper, we have designed and fabricated a small size wide-band monopole antenna which can integrate the frequency of previous business mobile communication system by adding 4 PCS of post type parasitic element on top-loaded sleeve monopole antenna. We have observed the properties of return loss upon a parameter change of element, and we also examined radiation properties in the band of PCS, W-CDMA, WiBro, W-LAN and S-DMB in order to make sure the suggested antenna's wide-band properties. We have found that the proposed antenna has omni-direction in horizontal plane and figure eight-direction in vertical plane, and we could have good return loss($Return\;loss{\leq}-10\;dB$) and $1.14{\sim}3.66\;dBi$ gain in $1.67{\sim}3.55\;GHz$ of frequency range($B/W{\fallingdotsep}72%$).

카지노산업의 마케팅전략에 관한 연구

이상우 한국관광정보학회 2001 觀光情報硏究 Vol.- No.9

While the tourism industry is being fostered as one of the national strategic industries and being regarded as more important, the casinos in Korea, due to their negative image of gambling resulting from too closed type of doing businesses, still remain at the early stage of development compared with those in other countries. But, in the case of the advanced countries in tourism industry, casinos are encouraged to influence and develop the tourism industry to get high added value or to provide recreational activities for the tired modern people, because they are known to contribute to increasing employment, income and tax revenue, enlivening local economy as well as improving the balance of international payment. Lately, the Korean government tries to bolster up casinos through the revision of relevant laws and regulations, keeping up with this trend of supporting casino industry. Nevertheless, these environmental changes from outside could become a big factor to press down business conditions against almost all of casinos that are small-scale except for some large-sized ones when the market in reality is flooded with a lot of small casinos to open and compete. Therefore, taking the reality into consideration, the author have attempted tp give some theoretical marketing strategy for casino industry to encourage the casino businesses. The study, starting with 'Chapter Ⅰ: the Introuction', takes a look at the conception of casino and its marketing along with the business environment in Chapter Ⅱ for theoretical perspective, and then, in Chapter Ⅲ, progress some criteria to choose target marketing for marketing strategy planning and market subdivision. Chapter Ⅳshows the direction for marketing strategy based on the traditional mix of 4P's, and finally there are the conclusions in Chapter Ⅴ. As a lot of changes are expected in casino industry in the offing, staffs engaged in casino industry will have to take more efforts and research to cope with the current circumstances.
