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.

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.

We experienced a case of cerebral hypoperfusion due to cyclosporine neurotoxocity confirmed only by Tc-99m ECD brain SPECT. A 53-year-old female had received allogenic peripheral blood stem cell transplantation due to refractory plasmacytoid lymphoma. Cyclosporine and steroid had been administrated to prevent graft versus host disease. Twenty days after transplantation, she became delirious and suffered from generalized tonic-clonic seizure. Immediately, brain MRI and MR angiography were performed and these studies did not show any abnormal findings. However, Tc-99m ECD brain SPECT showed diffuse hypoperfusion in the left cerebral hemisphere and blood cyclosporine level was 962.6 ng/ml. Cyclosporine administration was stopped and discontinuation of cyclosporine resulted in disappearance of all neurological symptoms. The same neurological symptoms recurred with cyclosporine re-administration for management of exacerbated graft versus host disease. In this case, Tc-99m ECD brain SPECT proved very helpful in the diagnosis of cycloporine neurotoxicity. (Korean J Nucl Med 2000;34:360-5)

As the seriousness of traffic noise pollution and psychological discomfort of people living within increase, the pursuit for better living environmental quality and the necessity of research for the appropriate responses based on analysis of impact by sound pollution has been emphasized ever before. This research was aimed to understand the noise characteristics by high-speed train through references and experimental data and to assess the noise level around the railroad track. Hopefully, this will be used as a tool for setting the direction of improvement, understanding the unavoidable noise impact by opening high-speed railroads, and preparing the noise prevention measures for exterior and interior space around stations.

As the economic growth and cultural need becomes increasing, construction of auditoriums which have better acoustical environment such as concert hall have been increased. In this paper, the analysis method of acoustical planning, basic theory of reverberation time are considered through literature. In addition, warmth and brilliance of acoustic is used as analysis point careful decomposition. K hall is selected as the objects of study to verify the validness of reverberation time and warmth and brilliance of acoustic, and measured reverberation time of auditorium is analyzed.

In this paper, the author has compared the psysiques, pitches and records of the rowing crew of 6 Japanese teams who participated in the 61st Japanese Rowing Championship and of 8 teams who participated in the 23rd Oxford Rowing Championship, for the race improvement of rowing. As a result, the followings have been obtained: (1) The teams in the Japanese Rowing Championship are superior to those of Oxford Rowing Championship in terms of heights and weights. The Average weight of a Korean team(Dankook University) is higher than those of other teams by 3kg, whilst these shows little difference in height. Therefore, it is suggested that the steady state of weights should be maintained. (2) The record of Juodaikaku team who won the Japanese Rowing Championship is 6’15”30 and that of Dankook University team who won the Oxford Championship 6’29”42, thus showing the difference by 4”12. The former maintained the steady lap time in each quarter, whilst the latter maintained the stagnant record in the last 500 quarter. (3) It is desirable that the pitches should be adjusted in consideration of the race management of the rival team and the race ability.
