The study aimed to identify leaf sheath through the investigation a characteristic of leaf by planting depth and leaf sheath function through the investigation of effect of leaf sheath removals on growth and flowering in forcing of Lilium cultivars. The number of leaf sheath of 'Jolanda', 'Dream Land', 'Casablanca' were 6, 5, 11 in 0㎝ planting depth and 6, 5, 14 in 6㎝ planting depth. The number of leaf sheath in 'Jolanda' and 'Dream Land' were little different in according to planting depth. The other hand, the number of leaf sheath in 'Casablanca' were increased 3 when it were planted in 6㎝ planting depth. As leaf sheath were removed, plant height and stem root growth were decreased in 'Le Reve' and 'Casablanca'. Whereas the growth of basal root and flower number varied among of Lillium and stem diameter, the days of flowering and flower size were little different.

목적 : 국내 병원에서의 정주 ciprofloxacin 사용의 적정성을 평가하고자 하였다. 재료 및 방법 : 2003년 9월 25일부터 8개의 대학병원에서 정주 ciprofloxacin을 받았던 290명의 연속적으로 모집한 성인환자를 대상으로 약제사용 평가(DUE)를 전향적으로 수행하였다. 이 연구에 사용된 DUE 기준은 미국병원약사회의 기준을 국내 실정에 맡게 수정하여 사용하였으며 1) 사용의 정당성에 관한 항목, 2) 사용 시 준수되거나 시행되어야 할 사항에 대한 항목, 3) 부작용에 대한 항목, 4) 치료 효과에 대한 항목으로 나누어 조사하였다. 결과 : 환자의 평균 나이는 54세였다. 33예(26.9%)에서만 약제 사용의 적정성 측면에서 기준을 만족하였고 91예(73.1%)에서는 사용이 적절하지 않았다. 정주 cipro-floxacin의 부적절한 사용의 흔한 원인은 수술 전후의 예방약 사용, 비뇨기계 처치 전의 예방적 사용, 열성 질환에 대한 경험적 사용 등의 순이었다. 사용 시 준수사항 의 측면에서는 사용 전 배양검사(73.8%)와 사용 중 배양검사(68.6%)가 낮은 수행 정도를 보였으나 그 외는 비교적 높은 적정성(82.4-100%)을 보여주었다. 정주 ciprofloxacin사용의 합병증은 드물었다. 치료 효과의 면에서 치료반응은 93.3%였다. 결론 : 약제 사용의 정당성 기준에 따른 정주 cipro-floxacin의 부적절한 사용은 연구에 포함된 대학병원에서 매우 흔하였다(73.1%). 그러므로 적절한 항생제 사용에 대한 교육과 제도적 장치가 매우 필요한 것으로 판단되었다. Background : To evaluate the appropriateness of intravenous (IV) ciprofloxacin usage in university hospitals in Korea. Materials and Methods : We prospectively evaluated the appropriateness of drug usage in 290 consecutive adult patients who received IV ciprofloxacin in eight teaching hospitals during the period from September 25, 2003 to November 15, 2003. Drug use evaluation (DUE) in this study was based on the modified standard by the American Society of Hospital Pharmacy with regard to the justification of drug use, critical and process indications, complications, and outcome measures. Results : Average age of the patients was 54 years. The use of IV ciprofloxacin was appropriate only in 33 cases (26.9%). Common reasons for inappropriate use of IV ciprofloxacin include perioperative uses or prophylactic injection before urologic procedures, and empirical therapy for febrile episodes. Most of the "critical indications" and "process indications" showed high rate of appropriateness (82.4-100%). However, the rate of taking culture and sensitivity test before (73.8%) and during ciprofloxacin use (68.6%) were low. Complications with ciprofloxacin use were rare. In 93.3% of cases, ciprofloxacin treatment was clinically effective. Conclusion : Use of intravenous ciprofloxacin is frequently inappropriate in tertiary care hospitals in Korea. Implementation of education program and antibiotic control system is critical in improving the appropriateness of antimicrobial use.

장영근(Young-Gun Jang),김현수(Hyun-Soo Kim),최훈상(Hoon-Sang Choi),오대곤(Dae-Kon Oh),최인훈(In-Hoon Choi) 한국진공학회(ASCT) 1999 Applied Science and Convergence Technology Vol.8 No.3(1)

In/PCl₃/H₂ chloride VPE법을 이용하여 높은 순도를 가지는 undoped InP 에피층을 성장하였다. InP 에피층은 630℃의 성장온도와 1.2×10^(-2)의 PCl₃/H₂ 몰비에서 최적화되었으며, photoluminescence(PL) 측정을 통하여 성장된 undoped InP 에피층의 이동자 농도는 10¹⁴㎝-³ 이하인 것을 확인하였다. 또한, 1.55 ㎛ buried-heterostructure laser diode(BH LD)의 구현을 위하여 반응성 이온시각(RIE: reactive ion-etched)에 의한 mesa 구조 위에 높은 비저항을 가지는 undoped InP을 선택적으로 재성장하였다. 재성장 온도는 620℃에서 640℃까지 변화시켰으며, 재성장 온도가 증가함에 따라 평탄한 표면을 가진 에피층이 성장되었다. 이것은 성장온도가 높을수록 {111}B 면에서 반응물질의 표면 확산계수가 증가함을 나타낸다. Undoped InP epilayers with high purity were grown by using In/PCl₃/H₂ chloride vapor phase epitaxy. It was found that the growth of InP homoepitaxial layer is optimized at the growth temperature of 630℃ and at the PCl₃ molar fraction of 1.2×10^(-2). The carrier concentration of InP epilayer was less than 10¹⁴㎝-³ from the low temperature (11K) photoluminescence measurement. Growth behavior of undoped InP current blocking layer on reactive ion-etched (RIE) mesas has been investigated for the realization of 1.55 ㎛ buried-heterostructure laser diode (BH LD), using chloride vapor phase epitaxy. On the base of InP homoepitaxy, InP current blocking layers were grown at the growth temperatures ranging from 620℃ to 640℃. Almost planar grown surfaces without edge overgrowth were achieved as the growth temperature increased. It implied that higher temperature enhanced the surface diffusion of the growth species on the {111}B planes and suppressed edge overgrowth.

목적 : 선천성 고혈압 흰쥐(SHR)와 정상 혈압 흰쥐(WKY)의 혈관 평활근 세포를 배양하여, 그 성장 특성을 조사하였다. 대상 및 방법 : SHR 및 WKY를 pentobarbital(50㎎/㎏)로 마취하여 적출한 흉부대동맥으로부터 혈관평활근세포를 얻었으며 이 세포를 이차배양하여 일정한 시간간격으로 trypsin을 처리하여 세포를 떼어낸후 혈구계(hemocytometer)로 세포수를 헤아렸다. 결과 : SHR과 WKY에서 얻은 혈관평활근세포에서 형태학적 차이는 없었고, SHR이 WKY보다 밀생상태에 더 빨리 도달하며 밀생상태에 도달했을때 SHR이 WKY보다 세포밀도가 더 높게 나타났다. 결론: SHR이 WKY보다 증식속도와 증식밀도가 더 높게 나타나는 것으로 보아 SHR에 성장 억제 조절 기전의 장애가 있음을 시사한다. To study the generation and processes of hypertension, characteristics of vascular smooth muscle cell were observed in cultured aortic smooth mescle cell from spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY). The degree of cell proliferation increased with escalating concentrations of fetal bovine serum(FBS) in cells of both SHR and WKY control rats. These results have shown that 10% FBS, which was the usual concentration in culture medium, was better concentration of medium in cell proliferation than 5% FBS, 10% calf serum, 10% horse serum, or 1% bovine serum albumin. There were no detectable differences in the morphology of cells obtained from SHR and WKY. Comparative studies have shown that cultured vascular smooth muscle cells from SHR proliferated to a higher cell number, grew to a greater density, and have greater specific growth rate than those of the WKY. These results provide possibility of a disturbances on inhibitory conrol to vascular smooth muscle cell growth in SHR.

The current studies investigated the therapeutic effects of Ephedra sinica Stapf (ES) herb-acupuncture on the inflammatory responses of rat arthritic joint, which was induced by the intradermal injection of heat-killed Mycobacterium tuberculosis emulsified in squalene to the base of the tail. The measurements of body weight and articular index were exploited as the assessment methods addressing arthritic symptoms, and the expression profiles of cytokines such as TNF-α, IL-1β and IL-6 in the, rat joint were analyzed using RT-PCR. The articular indexes of arthritic rats were significantly restored after the treatment with ES herb-acupuncture. Although the clinical symptoms of arthritic rats were apparently alleviated by the ES treatments, their body weights were not recovered. It maybe due to the weight-loss and energy enhancement effects of ES extracts. The expression of TNF-α, IL-1β and IL-6 enes, which were highly stimulated in the knee joints of arthritic rats, were restored to the levels of normal rats after the ES treatment. The therapeutic effect of ES herb-acupuncture was not observed in ES-treated, non-acupoint arthritic group as a sham control. The ES herb-acupuncture into an acupoint ST36 was found to be effective in alleviating the arthritic symptoms in adjuvant-induced arthritis rats as regards the body weight, joint appearance and the expression profiles of inflammatory cytokines.

Intermittent aeration processes have been much of interest as an excellent alternative for nutrients removal for upgrading secondary wastewater treatment plants, with minimum modification. Also, operational flexibility of those proposes a good opportunity for newly planed plants. Here, a pilot study was conducted to evaluate the performance of a continuous flow intermittent aeration process (KSDeN^TM process). The influent was collected at the effluent channel of the grit chamber of a large sewage treatment plant. The influent characteristics with standard deviation were 243.2±170.9mg/L for TCOD_cr, 47.5 13.9mg/L for T-N, 8.4±8.3mg/L for T-P and 5.2±1.8 for C/N ratio. Effluent of 1^st sedimentation tank was 208.2±87.6mg/L for TCOD_cr, 35.0±10.3mg/L for T-N, 4.8±1.9mg/L for T-P and 6.1±2.3 for C/N ratio. The average removal efficiencies of TCOD_cr, T-N and T-P were 93.6, 77.0 and 86.4% and effluent TCOD_cr, T-N and T-P concentrations were 12.5, 9.2 and 0.7mg/L respectively, satisfying regulatory limits. Alkalinity deficiency was not observed during the oxic periods, which is one of the special features of an intermittent aeration process. The results showed higher COD, T-N and T-P removal efficiencies and stability with varying influent conditions, compared to other conventional fixed phase nutrients removal processes.
