Background/Aims: Inflammatory diseasas of the pancreas are not uncommon. The advanced age is one of the significant factors in assessing the severity of acute pancreatitis. It has been shown that the biliary tract disease is a more frequent cause of acute pancreatitis in the elderly than in the young. With the increased life span, the elderly are comprising a large proportion of the population. As a result, physicians are more often being faced with acute pancreatitis in the elderly. The purpose af this study was to evaluate clinical features of acute panereatitis in the elderly. Methods: A total of 188 patients with acute pancreatitis were reviewed. We investigated the differences of clinical characteristics between the elderly patients aged over 60 and the young patients aged under 60. Results: The sex distribution showed male preponderance in the young patients (M:F=2.4:1), but was nearly equal in the elderly patients (M:F=1.1:1). The most common cause of acute pancreatitis in the elderly was biliary tract disease (52.5%), while alcohol abuse was the most common cause in the young patients (38.8%), Local complications of acute pancreatitis, such as psuedocyst, necrosis, abscesses were not differently shown between the elderly (16.9%) and the young (20.2%) patients. Systemic complications including acute puhnonary failure occurred more frequently in the elderly patients than the young patients. The mortality rate of the elderly patients (5.1%) was not significantly different from that of the young patients (3.1%). Conclusions: To detect correctable underlying bihary tract diseases the elderly patients with acute pancreatitis should be completely investigated using endoscopic retrograde cholangiopancreatography (ERCP). In addition, the patient should be closely monitored for the development of the systemic complications during the disease process.

This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

Midazolam의 경비투여와 경구투여 시 진정효과에 대한 비교연구

박헌동,이창섭,이상호,이난영 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.3

Midazolam은 현재 치과에서 널리 사용되고 있는 의식하 진정용 약물이다. 그러나 주로 경비투여로 사용될 뿐 경구투여 특히 소아에서 경구투여에 대한지침이 없어 본 연구를 통해 midazolam의 경구투여 시 진정효과에 대해 알아보고자 하였다. 전신상태가 양호하며 2회 이상의 치료가 필요한 남아 15명, 여아 13명, 총 28명의 환아를 대상으로 midazolam (Dormicum??, Roche)을 경비투여(0.2mg/kg)와 경구투여 (0.5mg/kg)하여 치과치료를 시행한 후 치료과정을 6단계로 구분하여 각 단계별로 수면지수와 울음지수, 움직임지수, 전반적인 행동지수를 측정, 비교하여 다음과 같은 결과를 얻었다. 1. 전체 치료과정동안 수면지수와 울음지수, 움직임지수, 전반적인 행동지수 비교 시 Ⅰ군 (경비투여)과 Ⅱ군(경구투여) 사이에 유의한 차이가 없었다(p>0.05). 2. 보호자 설문조사 결과 Ⅰ군에서는 67.8%의 보호자가 투여 시 아이가 고통스러워한다고 답하였으며 Ⅱ군에서는 17.8%의 보호자가 투여에 어려움이 있다고 답하였다. 3. 귀가 후 행동양상에 대한 질문에서 '평상시와 비슷하다'가 Ⅰ군에서는 78.6%, Ⅱ군에서는 57.1%로 경비투여 시 더 빠른 회복을 보이는 것으로 나타났다. 위와 같은 결과를 종합하여 볼 때 midazolam의 경구투여는 경비투여와 유사한 적절한 진정효과를 가지면서 환자에게 더 잘 받아들여지는 투여방법으로 생각된다. The purpose of present study was to compare the sedative effect of intranasal and oral midazolam treatment. The study was conducted on twenty eight child patients who required at least two visits. All the patients showed a good physical status (ASA-I). The patient was randomly assigned to receive midazolam either intranasal (Group Ⅰ, 0.25 mg/kg) or oral (Group Ⅱ, 0.5mg/kg) route at each visit. Treatment procedure was divided into six stages. In each stage, sleep score, crying score, movement score and overall behavior score were evaluated. The overall results can be summarized as follows: 1. Through all treatment procedures, no significant difference was observed between Group Ⅰ and Group Ⅱ in terms of sleep, crying, movement and overall behavior index. 2. In a questionnaire to the parents, 67.8% of parents answered that the child suffered at intranasal administration, while only 17.7% of parents responded the same way at oral administration. 3. In a questionnaire regarding patients' behavior at home after midazolam treatment, 'Similar to normal behavior was 78.6% in Group Ⅰ and 57.1% in Group Ⅱ, indicating that intranasal treatment of midazolam may be more effective for the recovery.

<P><B>Abstract</B></P> <P>Aluminum oxide (Al<SUB>2</SUB>O<SUB>3</SUB>) has excellent properties in terms of hardness, abrasion resistance, refractive index, electrical insulation and chemical stability; therefore, it has been used in various optical applications such as for resistance random access memory active layers and nano-micro polishing. In this study, a functional Al<SUB>2</SUB>O<SUB>3</SUB> nanoparticle resin with refractive index control was developed and various nano-micro structures were formed using UV-nanoimprint lithography. It is also possible to adjust and measure the desired optical properties by controlling the specifications of the formed Al<SUB>2</SUB>O<SUB>3</SUB> structures. It was confirmed that imprinting is possible not only on traditional rigid substrates but also on flexible ones. Furthermore, scanning electron microscopy showed that the various Al<SUB>2</SUB>O<SUB>3</SUB> nano-micro structures were well formed. The effect of annealing temperature on the phase change and crystallinity was investigated by X-ray diffraction. The hardness and Young's modulus were also measured by using a nanoindenter. The refractive index of Al<SUB>2</SUB>O<SUB>3</SUB> dispersion resin composition was examined using an ellipsometer. Moreover, the optical characteristics of each Al<SUB>2</SUB>O<SUB>3</SUB> nano-micro structure were measured by UV–visible spectroscopy.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Manufacture of Al<SUB>2</SUB>O<SUB>3</SUB> dispersion solution with adjustable refractive index </LI> <LI> Fabrication of nano-micro structures using Al<SUB>2</SUB>O<SUB>3</SUB> dispersion resin </LI> <LI> Characterization of Al<SUB>2</SUB>O<SUB>3</SUB> dispersion resin and Al<SUB>2</SUB>O<SUB>3</SUB> nano-micro structure </LI> </UL> </P>

오차수정모형을 이용한 산업별 수출ㆍ입방정식 추정에 관한 연구

박헌영 연세대학교 경제연구소 2001 延世經濟硏究 Vol.8 No.1

본 연구의 목적은 오차수정모형을 이용하여 시장평균환율제도에 이어 1997년 12월부터 완전변동환율제도가 채택되어 외환시장에서 확되되고 있는 환율변동의 산업별 수출ㆍ입에 미치는 영향을 분석하는 데 있다. 1990년대 월별 자료를 이용하여 대미 실질환율과 대일 실질환율로 구성된 실질실효환율과 GARCH(1,1)을 이용하여 추정한 실질실효환율변동성, 미ㆍ일 실효생산성 또는 한국의 생산성지수를 추정 변수들로 사용하였다. 분석결과는 월별 자료이기 때문에 일부 산업의 수출방정식에서 공적분 관계가 성립하지 않는 것으로 나타났으나 장기 실질실효환율수준이 유의적으로 영향을 주는 것으로 단기에는 차분된 실질실효완율보다는 환율변동성이 더 크게 영향을 주는 것으로 각각 나타났다. 이것은 1990년대 환율변동이 발생할 때, 우리경제는 수출수량보다는 수출단가를 또는 수출보다는 수입수량이나 수입단가를 조정하는 소규모 개방경제의 특징을 보여 준 것으로 해석된다.

朴 憲,劉永三 건국대학교 자연과학연구소 1999 建國自然科學硏究誌 Vol.10 No.2

This study was conducted in order to measure formaldehyde emission with the passing of one year from particleboard(two kinds of raw material's shape - sliver and strand) bonded with Urea resin which was made of different F/U molar ratio. The Urea resin was manufactured six kinds of Formaldehyde/Urea molar ratio 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0. Formaldehyde emission values were compared at 1, 3, 7, 15, 30, 90, 150, 250, and 365 days after board manufactured. The results were as follows : 1. I year after board manufactured, both Sliver and Strand Particleboard satisfied the emission limit (E₂: 5㎎/ℓ - F3140 classification) of KS standard with 1.0, 1.2, 1.4 and 1.6. 2. The Partidcleboards with F/U molar ratio 1.4 and 1.6 satisfied E2 limit only in 150 days and 365 days respectively. 3. Formaldehyde emission amount of Sliver Particleboard was similar to Strand Particleboard depended on each F/U molar ratio. However, the formaldehyde emission pattern was influenced with the shape of raw materials(particle shape).
