Paclitaxel과 cephalosporines(제 1세대인 ceftezole sodium과 cephradine, 제2세대인 cefamandole sodium과 cefmetazole sodium, 제3세대인 cefoperazone sodium과 cefotaxime sodium 그러고 제4세대인 cefepime hydrochloride)을 $5\%$포도당주사액 그리고 $0.9\%$ 염화나트륨주사액과 함께 Y-Site 장치를 써서 환자에게 주입할 때 paclitaxel의 안정성에 관하여 연구하였다. Paclitaxel 0.3 mg/ml 및 1.2 mg/ml과 cephalosporines 20 mg/m을 각각 1 : 1로 혼합한 후 0, 1, 2, 4, 12시간 시점에서 paclitaxel의 농도를 HPLC로 분석하였다. 방해물질에 의한 분석오차를 줄이기 위해 분석법을 여러 상태에서 확인하였으며, 각 농도에서 3차례씩 실험하였고 각 샘플은 2차례 반복하여 HPLC로 분석하였다. 분석전에 각 시료의 투명도, 색의 변화, 침전상태 및 pH를 검사하였다. Paclitaxel 0.3 mg/ml 및 1.2 mg/ml와 cephalosporines 20 mg/ml를 각각 혼합하였을 때 12시간 동안 안정하였으며, 주사액의 혼탁이나 색의 변화 및 침전은 나타나지 않았으며 pH도 변하지 않았다.

세계 제 2 차대전이 끝난 이후로부터 40여년간, 현대 관측천문학을 이끌어 온 Palomar 산의 500cm 반사망원경은 드디어 차세대망원경에게 leadership을 넘겨주게 되었다. 자금염출이 여의치 않아 그동안 부진했던 초대형망원경 건설이 드디어 boom을 일으키게 된 것이다. 가주공과대학의 10m 반사망원경이 제작 중에 있고, Ohio주립대학도 10m 쌍통반사망원경 건립을 추진 중에 있고, 일본도 7.5m 반사망원경 건립을 검토 중이다. 한국은 1.5m~2m 반사망원경 제작이 구체화되어가고 있으니, 1970년, 불과 40cm 반사경 1대만 갖고 고군분투하던 그때를 초기하면 실로 감계무량하다 아니할 수가 없다. 그러나 NASA는 또 한편, 차세대망원경으로서 Space Shuttle을 이용하여 위성망원경을 발사할 계획을 1965년에서부터 구상하여 수차에 걸친 발의·부결을 거듭한 끝에, 드디어 1977년, 미국회의 건조인준을 얻었다.

The study was to investigate the bionomics, host plants, and oviposition preference of Hishimonus sellatus Uhler. It has 5 generations under natural conditions and the peak of the 3rd generation was observed about mid and late August. Its average developmental durations were 80 days in spring, 69 days in summer, and 77.8 days in autumn. The lengths of each stage were 0.8mm in eggs, 0.9mm in 1st instar, 1.4mm in 2nd instar, 2.1mm in 3rd instar, 2.5mm in 4th instar, 3.2mm in 5th instar, 4.1mm in female, and 3.8mm in male. Hishimonus sellatus overwintered as egg in Morus alba, Humulus japonicus, and Zizyphus jujuba begining mid October, and attacked the shoot of M. alba and H. japonicus about mid and late May, migrated to the Zizyphus jujuba from late June to early July. Female oviposites 32~62 eggs into epidermis of shoot, vagina and vein during their life. The preferred host plants of H. sellatus were Humulus japonicus, Morus alba, Zizyphus jujuba, and ligustrum obtusifolium. Highly preferable oviposition site was H. japonicus, M. albal, Z. jujuba, and L. obtusifolium, etc. On audlt longevity, the host plants as H. japonicus, M. alba, and Z. jujuba were 43$\pm$2 days and A. brevipedenculata, C. mimosoides, L. obtusifolium, V. rosa, A. sinicus and, A. graveolens were more than 25 days, and other host plants were less than 20 days.

For the purpose of finding out the effect of heat treatment on biological response and mutation rate, rice seeds were heat treated before and after gamma irradiation. 1. At a dose of 20 KR, pre-irradiation heat treatment showed reduced biological damage and increased mutation rate as compared with non-heat treatment. 2. Mutation frequency was increased in post-treatment of heat shock than in pre-irradiation heat treatment and non-heat treatment. 3. Pre-irradiation heat treatment at 6$0^{\circ}C$ for 30 minutes markedly reduced the biological damage and increased the mutation rate. 4. Mutation spectrum in heat treatment was different from non-treatment.

Purpose: Detection of TSH-binding inhibitor immunoglobulin (TBII) in patients with hyperthyroidism is an important result of Graves' disease (GD) and hyperthyroidism treatment. This has been made out an inspection by commercial radio-receptor assays. To increase the sensitivity and the specificity of the assay, many results of the assay were reported. In this study we evaluated the clinical usetulness of TBII assays by the Comparative method. Material and Methods: We were measured by using healthy control group (n=30, male=20, female=10) of Seoul National University Hospital Healthcare System Gangnam Center from January to March in 2009. Similarly, We were measured by using hyperthyroid (TSH<$0.05\;{\mu}IU/mL$, FT4>1.80 ng/dL) experimental group (n=58, male=14, female=44) of division of endocrinology and metabolism department of internal medicine Seoul National University Hospital from January to March in 2009. We made a comparative study of each two assays from the first generation to the third generation. We were used of TSAb assay as a measurement of GD diagnostic technique. Results: The specificity of healthy control group was 100% according to the generation. (Specificity=100%, n=30) The sensitivity of hyperthyroid experimental group were the first generation RSR<%> (79.3%, n=58), RSR (51.7%, n=58), the second generation RSR-CT (93.1%, n=58), BRAHMSCT (98.3%, n=58), the third generation ELISA (94.6%, n=56), ECLIA (97.7%, n=58) and TS-Ab<%> (93.5%, n=46). Conclusion: We were used of TSAb assay as a measurement of GD diagnostic technique, The result of data showed a high correlation between the third generation TBII assay and the second generation TBII assay ($R^2$=0.923). Instead of the first generation assay, the second generation assay can be more useful in clincal diagnosis.

6-DOF flight simulation program is most generally used M&S tool in domestic missile development procedure. The 6-DOF M&S method, however, cannot validate the performance of a imaging seeker-adopted missile in various conditions. A M&S tool for the analysis of the integrated-flight simulation is required since the tracking performance of the imaging seeker is highly dependent on the missile maneuvering, which introduces the displacement and rotation of the target in the seeker imagery. Through the development of the $3^{rd}$ generation anti-tank missile, Raybolt, the integrated-flight M&S tool was developed and applied to the missile configuration design. It integrates synthetic image generation S/W, imaging tracker, and flight simulation program and computes the main system performance criteria, hit probability by Monte-Carlo Simulation. In this paper, the issues in the $3^{rd}$ generation anti-tank missile configuration and the integrated-flight M&S method and results are described.

The purpose of this study is to divide the generations into Generation M and Generation Z and analyze the similarities and differences in the experiences, values, and fun through dance. To this end, the characteristics of the MZ generation were confirmed in detail, and the relationship between perceived value and fun factors was verified through various experience elements to suggest implications for the growth of dance. The subjects of the study were those who had experience with dance or had participated in dance classes. The survey was conducted from May 1 to May 30, 2024. Exploratory factor analysis, reliability analysis, multiple regression analysis, and difference analysis were conducted to verify the hypothesis. The research results are as follows. First, it was confirmed that for the MZ generation, educational and esthetic experiences of dance influenced the value. Second, it was confirmed that for the MZ generation, educational and esthetic experiences of dance had an impact on enjoyment. Third, in the experience factor, the differences of the MZ generation were shown in entertainment, educational, aesthetic, and esthetic experiences. Fourth, in the value factor, the differences of the MZ generation were shown in artistic values. Fifth, in the fun factor, the differences of the MZ generation were shown in a sense of accomplishment. finally, the commonalities of the MZ generation were shown in the value factor as physical, emotional, and sociocultural values. In the fun factor, they were shown as physical and mental fun and social cultivation. Through this study on generational differences in dance, it was confirmed that dance is an important means of providing social and cultural values beyond a simple art form, and the possibility of growth through differentiated competitiveness was presented.
