연구목적: 이 다기관 공동임상연구는 사용 중인 항정신병약물을 ’직접 교체 방법’또는 ’시작-감량 교체 방법’중 한 가지 방법으로 올란자핀으로 교체한 후, 안정성 측면에서 두 교체 방법 간의 비교와 교체후의 변화를 관찰하기 위한 것이다. 방법: 국내 13개 병원의 입원 및 외래에 내원한 환자들 중 ICD-10 지단기준으로 정신분열병에 해당되며, 임상적으로 항정신병약물 교체가 필요한 환자를 대상으로 하였다. 두 가지 교체 방법 중 한 가지를 무작위로 피험자에 적용하였으며, ’직접 교체 방법’에 배정된 경우에는 사용중인 항정신병약물을 일시에 중단하고 10㎎의 올란자핀을 바로 투여하였고, ’시작-감량 교체 방법’에 배정된 경우는 10㎎의 올란자핀 투여하고 2주에 걸쳐서 기존 약물을 감량하여 중단하였다. 올란자핀 사용기간은 총 6주이며, 용량은 5∼20㎎ 범위로 제한하였다. 한정성 평가를 위해서 체중, 생명징후, 자발적인 이상반응 복, 실험실 검사 그리고 Simpson-Angus Scale(SAS), Barnes akathisia rating scale(BARS), Abnormal involuntary movement scale(AIMS). Liverpool University neuroleptic side effect rating scale(LUNSERS)등을 이용하였다. 결과: 총 103명의 정신분열병 환자를 대상으로 하였다. 사용한 올란자핀의 용량, 벤조디아제핀의 병용률, 탈락률과 탈락 사유, 자발적인 이상반응 보고, 생명징후, 실험실 검사 그리고 대부분의 부작용 척도 상에서 임상적으로 의미 있는 차이를 두 교체 방법간에 발견하지 못하였다. 다만 AIMS의 감소는 ’직접 교체 방법’군에서 보다 적었고, 항콜린제의 병용률은 ’시작-감량 교체 방법’군에서 보다 많았다. 기저 상태에서 전체 피험자의 SAS와 BARS 점수는 각각 3.5점과 1.8점이었으며 70% 이상의 피험자가 고프로락틴 혈증을 보였다. 올란자핀으로 교체한 후, SAS, BARS, AIMS 점수의 유의한 감소가 있었으며 고프로락틴 혈증을 보인 피험자 분율도 약 30%이하로 감소하였다. 그러나 교체 방법과 상관없이 올란자핀 교체 후 유의한 체중 증가가 있었다. 결론: 이 연구를 통해 교체 방법에 관계없이 비교적 안전하고 용이하게 올란자핀으로 교체 할 수 있음을 알 수 있었다. 그리고 기존 항정신병약물을 올란자핀으로 교체함으로써 일부 부작용들을 줄일 수 있음을 간접적으로 관찰할 수 있었다. 하지만 이 연구는 여러 제한점과 문제점을 지니고 있기 때문에 보다 체계적인 연구를 통해 검정이 필요하리라 생각된다. Objectives: This multicenter clinical trial involving 13 hospital sites compared the safely of switching to olanzapine between ’direct switching method’ and ’start-tapering switching method’. Method: This study included both inpatients and outpatients who fulfilled the criteria for schizophrenia as defined in the ICD-10, and were in need to be appropriate for switching antipsychotics. Subjects were randomly assigned to one of the two switching methods. For ’direct switching method’group, previous antipsychotics were abruptly discontinued and 10㎎ of olanzapine was administered, and previous antipsychotics was gradually tapered for 2 weeks. Olanzapine was used for 6 weeks and the dose was adjusted within the range of 5-20㎎. The safety of switching to olanzapine was measured with vital sings including body weight, adverse events reported spontaneously, laboratory tests, and various scales such as Simpson-Angus Scale(SAS), Barnes Akathisia Rating Scale(BARS). Abnormal Involuntary Movement Scale(AIMS), and Liverpool University Neuroleptic Side Effect Rating Scale(LUNSERS). Results: 103 patients were switched to olanzapine in this study. The comparison between two switching methods did not show any significant difference in the dosage of olanzapine used, the concomitant use of benzodiazepine, the rate and reasons of drop-out, the adverse events, vital signs, laboratory tests, and most scales for measuring side-effects. However, the decrease in AIMS scores was significantly lower in ’direct switching method’ group, and the concomitant use of anticholinergics was comparatively greater in ’start-tapering switching method’ group. At baseline, SAS and BARS scores were 3.5 and 1.8 points respectively, and more than 70% of the subjects showed hyperprolactinemia. After switching to olanzapine, SAS, BARS, and AIMS scores were significantly decreased and the proportion of the patients with hyperprolactinemia was also decreased to less than 30%. However significant weight gain after the treatment of olanzapine was observed regardless of switching method. Conclusion: This study may suggest that switching to olanzapine can be done with relatively high safety regardless of switching methods and olanzapine can significantly decrease some side-effects induced by other antipsychotics.

This paper presents flux-to-dose-rate conversion factors for neutrons and gamma rays based-on the Americaan National Standard Institute(ANSI) N666. These data are used to calculated the dose rate distribution of neutron and gamma ray in radiation fileds. Neutron flux-to-dose-rate conversion factors for energies from ?? to 20 MeV are presented; the corresponding energy range for gamma rays is 0.01 to 15Mev. Flux-to-dose-rate conversion factors were calculated, under the assumption that radiation energy distribution has nonlinearity in the phantom, have different meaning from those values obtained by monoenergetic radiation. Especially, these values were determined with the cross section library. The flux-to-tose-rate conversion factors obtained in this work were in a good aggreement to the values presented by ANSI. Those data will be a useful for the radiation shielding analysis and the radiation dosimetry in the case of continuous energy distribution.

葡萄 Campbell Early 의 無核果 生成 및 成熟促進을 위하여 GA₃ 濃度別 그리고 몇 가지 覆袋處理를 한 實驗結果는 다음과 같다. 1. 果房重과 果粒數는 滿開 8日前 處理가 適期로서 果房重은 無處理에 비해 76.4%, 果粒數는 80.6%였다. 2. 1果房當 無核粒率(92%)과 100粒中 種子數(12個)는 滿開 18日前, Gibberellin 處理+cellophane紙 覆袋區가 가장 良好하였다. 3. 果粒數와 種子數(r=0.826) 또한 種子數와 果重間에는 정의 相關關係(r=0.841)를 나타내었다. 4. 糖度는 無處理區보다 cellophane紙 覆袋區가 9.34% 로서 높았다. 含水量과 灰分은 無處理와 新聞紙 覆袋區가 높았고 cellophane 紙 覆袋區가 낮았다. 5. vitamin C 含量은 Gibberellin 處理時期가 빠르고 無核率이 높을수록 낮은 傾向이엇다. 處理間에 있어서는 無處理와 parchment紙 袋覆區 많았고 cellopnane紙 袋覆區가 含量이 적었다. 6. Gibberellin 處理時期를 앞당기고 cellophan紙 袋覆를 하면 無核率이 높은 反面 果粒數 果重이 減少되고, Gibberellin 處理時期를 늦추고 新聞紙 覆袋를 하면 果粒數 果重은 增加하지만 無核率이 낮아졌다. The results obtained by the Gibberellin and bagging treatment on the Campbellearly grape are as follows: 1. The suitable period of treatment for cluster weight and number of berry are to be before 8 days of full bloom. The cluster weight was 76.4% and number of berries were 80.6% compared with control. 2. The ratio seedless berries of 92% per cluster, and number of 12 seedss in 100 beries were showed the best on before 18 full bloom at the bagging plots of Gibberellin treatment+cellophane paper. 3. Number of berry and number of seed (r=0.826) also were showed mutual relation of plus between the number of seed and fruit weight. 4. Soluble solid was showed higher of 9.3% at the cellophane paper bagging plot and 9.34% at the parchment paper bagging plot than the control. Juice content and ash were showed high at the conthol and newspaper bagging plot, and low at the cellophane paper bagging plot. 5. The content of vitamin C was showed low tendency at the higher of the seedless ratio with the quick Gibberellin treatment period. At the betweentreatment, the control and parchment paper bagging plot were showed much, and showed less content at cellophane paper bagging plot. 6. In advance the period of Gibberellin treatment and had cellophane paper bagging then the ratio of seedless would be high, but on the contrary, the number of berry and fruit weight decreased, and had delay the period of Gibberellin treatment and had the newspaper bagging, the number of berry and fruit weight would be increased but the ratio of seedless was low.

The purpose of this study was undertaken to determine the effects of orthognathic surgery on speech. The hyposis stated herein is that functional behaviors of the dentofacial complex, such as speech production, may be adversely affected by deviations of a structural nature(especially, Class III malocclusion) . Twenty adults with Class III malocclusion(13 female and 7 male) were studied preoperative, immediate postoperative and either 6 or 12 months postoperative lateral cephalograms. They had mandibular prognathism and had undergone mandible setback operation. The position of tongue, soft palate(Uvula), hyoid bone, respiratory track width, and pharyngeal depth were assessed on lateral cephalograms with 23 cephalometric variables, ANOVA, Paired t-tests and Pearson's product-moment correlation coefficient tests were used to evalute the operative changes in all cephalometric parameters. A experienced speech and language pathologists performed narrow phonetic transcriptions of tape-recorded words and sentences produced by each of the ninth patients and the recording tapes were analyzed by phonetic computer program(Computerized Speech Lab(CSL) Model 4300BI(U.S.A.)) These judges also recorded their ratings of each patient's overall consonants, hypernasality, hyponasality, and articulation proficiency. The results obtained are as follows ; 1.There were significant changes in distance of posterior pharyngeal wall to tongue (TI-TW2, TS-TW3) after the surgery at 6 months postoperatively(each p<0.01 p<0.05) 2.The posterior tongue point(TI, TS, PPT) moved posteriorly after surgery and remained to its changed position at 6 months postoperatively(p<0.05) . The displacement of tongue was correlated with the movement of mandibular setback amount(p<0.05). The hyoid bone moved posteriorly superiorly after immediate postoperative period. There was significant changes in hyoid bone movement after immediated post-operative period(p<0.05), but returned to its original position during the follow-up period(p>0.05) 3.The soft palate was displaced posteriorly superiorly after immediated operative period and remained to its changed position at 6 months postoperatively(p<0.05) ANS-PNS-SPT angle increasing, PPU-PPPo distance narrowing was showed after surgery, and remained its appearance 6 months postoperactively (p<0.05) 4.There were significant changes in formant value and squre diagram of vowel sound after the orthognathic surgery and the follow-up period. There were significant changes in /ㅅ/sound and posterior tongue sound. 5.The posterior movement of tongue and the posteriosuperior movement of soft palate was correlated with mandibular setback amount after orthognathic surgery. On the vowel squre diagram, the author found that the place of articulation after operation moved downward, backward, upward. 6.In assessing speech abnormalities, dental occlusion should be considered as a contributing factor. The vast majority of subjects with preoperactive misarticulations eliminated or reduced their errors following orthognathic surgery. There was significant difference in speech impovement between pre- and post-operation.
