The purpose of this study was to investigate the changes of hardness and microstructure of Dongchimi cooked with various source of water(distilled water, purified water, Cho Jung Carbonated Natureal water). This study was conducted to observe the change of pH, total acidity, salt content, turbidity, texture and microstructure. Dongchimi cooked with source of water of water was fermented at 10℃ for 46 days. The changes of pH on Dongchimi cooked with various source of water decreased in all samples during fermentation period, and then showed a slowly decrease after 12 days of fermentation. The total acidity of Dongchimi cooked with Cho Jung Carbonated Natural water was arrived slowly at best tasting condition 0.3~0.4 point compared with other conditions. So Dongchimi cooked with Cho Jung Carbonated Natural water was continued to the best tasting condition for end of fermentation. At early stage of fermentation, the changes of turbidity of Dongchimi used Cho Jung Carbonated Natural water showed highly as compared with other test condition for 12th days of fermentation. The maximum cutting force of chinese radish of Dongchimi showed the highest value among all at the 25th day of ripening and then decreased gradually. The maximum cutting force of chinese radish of Dongchimi used Cho Jung Carbonated Natural water was the highest compared with other conditions at 25th day of fermentation. The calcium content of Dongchimi juice used Cho Jung Carbonated Natural water was observed high at the early stage of fermentation and showed the highest value at 25th day of ripening. The calcium content of chinese radish and Dongchimi juice of Dongchimi cooked with water purifier was lower than that of Dongchimi cooked with Cho Jung Carbonated Natural water, and was higher than that of Dongchimi cooked with Distilled water at the early stage of fermentation. The magnesium content in all samples increased gradually from the early stage of fermentation. The microstructure showed disintegration appearance of middle lamella and cell wall during fermentation period.

金在植,金京善,金重明,金榮泰,蔣卓仙,李鉉基 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

著者들은 家兎와 人體로부터 採取한 血淸과 諸臟器組織을 使用하여 ALPI 電氣泳動像을 觀察하고 生化學的 定量法을 利用하여 ALP의 活性度를 測定試圖하였으며 臟器特異性 沮害因子에 對한 影響을 觀察하였다. 家兎 血淸 및 諸臟器組織 ALPI電氣泳動에서 血淸은 ±의 活性度를 가진 α2와 α2/β分劃을 나타내었으며 肝組纖은 血淸보다 빠른 移動度를 가진 ??의 α_1과 α_2分劃을 나타내었다. 그리고 肝, 骨, 腎 淋巴腺, 脾臟 및 腸組織에서는 顯著하게 높은 活性度를 나타내는 各各 서로 相異한 分劃을 볼 수 있었으며 人體諸 臟器와大體로 類似하였으나 家兎 血淸의 ALP는 사람에서 와는 다르게 肝組織의 分劃과 一致하지 않고 오히려 骨組織과 더 잘 一致되는 것 같았다. ALPI 活性度에 있어서 家兎의 諸臟器는 生化學的 定量法으로 腎 ALP의 活性度가 49.5B.L. units로 다른 臟器組織에 비하여 顯著하게 높았으며, 그 다음은 脾臟, 脊椎骨, 肝, 肺淋巴腺 및 脾 順으로 높은 活性度를 나타내었으며 人體에 있어서는 胎盤, 骨, 小賜, 脾臟, 肝 및 腎臟의 順으로 높았다. 臟器 特異性 沮害因子에 對한 影響에 있어서 胎盤分劃은 特有하게 耐熱性을 나타내었고 보다 urea低抗性이며 肝分劃은 neuraminidase에 對하여 移動度의 遲延을 招來하였다. The studies upon cellulose acetate microzone electrophoretic patterns, quantitative estimation and effects of organspecific inhibitor on ALP isoenzyme of rabbit and human sera and various organ tissues were performed. On electrophoretic pattern the tissue ALP from the liver bone kidney lymph node spleen and intestine showed the characteristic fraction of high activities. The electrophoretic mobility of rabbit serum ALP was not correspond to the liver ALP as observed in human serum and it appeared to be rather corresponded to the bone ALP, which seemed to be the origin of ALP in serum of rabbit. In the quantitative measurement of tissue ALP activity the kidney ALP showed the highest level and the activity of the skeletal muscle ALP was the lowest(1.5 B. L. units), while higher activities were observable in placenta, bone, intestine, spleen, liver and kidney in order. On the effect of organ specific physico chemical agents the placental ALPI was highly stable to the heat and relatively resistant to urea while other organ ALPI were on the contrary. The neuraminidase seemed to effect to the motility of liver fraction.

김미자,국기용,김태원,박유환,김완중,허경,정춘해,홍순표 朝鮮大學校 附設 醫學硏究所 1993 The Medical Journal of Chosun University Vol.18 No.1

Inspite of possible effects for emesis following chemotherapy including cisplatin, nausea and vomiting are the most unpleasant side effects of cancer chemotherapy. None of the currently available antiemetic agents is entirely effective preventing emesis. Ondansetron, a 5-HT(5-hydroxytryptamine)_(3) receptor antagonist, has been shown to be effective antiemetic agent in the control of cisplatin induced emesis. Twenty solid tumor patients who are scheduled to receive cisplatin containing combination chemotherapy participated in a prospectively randomized study to compare the antiemetic efficacy and safety of ondansetron and metoclopramide. Ondansetron was given in dose of 8mg intravenous 30min before cisplatin and then 4hours and 8hours after cisplatin on day 1, and Ⅰ.Ⅴ. every 8hours from day 2 to 5. In the metoclopramide group, metoclopramide was given in dose of 2 ㎎/㎏ intravenous every 8hours from day 1 to 5. The control of emesis was graded in the following way : complete response, no vomiting : major response, 1-2 emetic episodes : minor response, 3-5 emetic episodes : failure, above 5 emetic episodes. Complete or major response of emesis was achieved 10 of 12(83.2%) patients receiving ondansetron and in 5 of 8(62.5%) patients receiving metoclopramide, but effectiveness was not significantly different. Ondansetron was at least as effective as metoclopramide therapy in controlling cisplatin induced emesis. Side effects in ondansetron was less than in Metoclopramide.

김정기 大韓神經精神醫學會 1982 신경정신의학 Vol.21 No.3

1981년 3월 19일부터 동년 11월 15일까지 고려병원 신경정신과에서 실시한 집단정신치료중 입원환자 집단에서 외래환자 집단으로 전환되는 시기인 6회에서 14회까지 9 sessions을 고찰한 결과, 다음과 같은 결론을 얻었다. 1. 입원환자와 외래환자 사이에는 아래와 같은 차이점이 있었다. ① 탈락율에 있어서 입원환자가 외래 환자에 비해 3배 이상 높게 나타났고(80%:25%), 이야기한 빈도는 1:1.58정도로 적게 나타났다. ② 좌석 위치는 입원환자는 입원환자끼리, 외래는 또 그들끼리 무리를 지어 앉는 경우가 많았다. ③ 소집단은 외래나 입원환자 끼리의 소집단이 5번으로(전체 7번)71%를 차지 했으며, 이런 소집단이 치료적인 면에서 이득보다는 파괴적 영향을 더많이 나타내었다. ④ 역동적 지도자의 출현은 한번을 제외하고는 전부 외래환자중에 나타났으며, 또한 특정 환자가 동일한 형태의 지도자 역활을 한 것으로 나타났다. ⑤ 내용 분석 외래환자는 정서적 분야에서 우울반응, 불안, 따뜻함을 그리고 내용 분야에서는 저항, 의존성, 치료적 조언등을 훨씬 많이 표현한 것으로 나타났고, 반면에 입원환자는 내용분야에서 추상적이고 비논리적 사고에서 높은 빈도를 보였다. 그러나 공격성을 비슷한 빈도를 보였다. 2. 침묵 집단침묵은 매회 평균 3번, 1회 13초로 아주 적었던 것으로 나타났다. 또한 침묵을 깬 사람은 치료자가 28번중 15번으로 절반 이상을 차지했다. 3. 상태의 변화에 대한 적응 입원환자가 퇴원후 처음 외래환자로 참석했을 때 심히 위축되어 집단에서 역활을 거의 하지 못했으나 2번째 참석부터는 외래환자로서의 역활을 잘했다. 4. 집단치료 시작전 먼저온 환자들이 집단에 미치는 영향 집단치료가 시작되기전 먼저온 환자들의 분위기가 그룹진행에 영향을 미치는 것을 관찰할 수 있었다. 결론적으로, 본 연구의 대상이 되었던 전환기의 9 sessions를 집단치료의 과정과 역동적인 면을 관찰해 볼때 외래환자 집단의 중간형태의 특징을 가진 것으로 나타났고, 또한 이 기간중 잦은 환자들의 교체로 집단자체의 안정성이 떨어졌으며 치료의 진행에 지장을 초래하였다. 그러나 이렇게 입원환자 집단을 외래환자 집단으로 전환시킴으로서 이 시기에 겪게되는 환자들의 현실적 어려움을 흡수하고, 정서적 동요를 막아주는 역활을 해 치료적인 면에서 도움이 되었다. On conduction group psychotherapy, it is common practice to form group separately, such as in-patients group or out-patients group. Accordingly, when in-patient transfers to out-patient group, difficulties arise not only because of lack of continuity in treatment, but also because they have to adjust their role in the new group. It would be ideal, if they participate in the same group even after discharge. So we formed a mixed group for this purpose. This article summarized some findings after we conducted this king group therapy in this transitional situation. From March to November 1981, group psychotherapy was conducted at the Department of Neuropsychiatry, Korea General Hospital. Nine sessions(from 6th through the 14th), which was the transitional period from the in-patient group stage to the out-patient group stage were evaluated clinically, The results of this evaluation were as follows 1. The differences between the in-patient members and out-patient members in this group were: a. Drop-out rate of the in-patients was three times more than the out-patient (80:25 percent) b. verbal products, however, were not much different(ratio 1:1.58). c. During sessions, there was a tendency that both in-patients and out-patients sit close with other members of their same group. d. Subgroups were formed seven times, however, from a therapeutic view point, they produced more adverse effects than favorable results. e. With one exception, leaders always emerged from the out-patient group, and it was found that a particular type patient would assume the same type of leadership role. f. Content analysis: In the emotional area, out-patients demonstrated more of depression, anxiety and warmth; in the content area, they demonstrated resistance and dependency as well as an ability to express therapeutic comments. On the other hand, the in-patients demonstrated a higher frequency of abstractive and illogical thinking, however, they showed a similar frequency in aggression. 2. Silencd: silence during group session occurred rather infrequently-three times on the average, each lasting 13 seconds. Silence was broken by the therapist on 15 out of 28 occasions. 3. Adaptation to changed status: When, an in-patient attened the group session as out-patient for the first time, he showed severe withdrawal and was unable to play a role in the group. From the second session on, however, he functioned well as out-patient. 4. Influence of earlier enrolled members on the group: They exerted a certain amount of influence on the atmosphere of the coming group process. It is concluded that this type of transitional intermediate group was therapeutically benefical for patients in lessening difficulties in resocialization and for prevention of emotional disturbance.

張志根,張鎬廷,金敏寧,嚴于鎔 단국대학교 1995 論文集 Vol.29 No.-

Pyroelectric (Pb, La) TiO_3 (PLT) thin films have been prepared on Pt coated MgO(100) substrate by RF magnetron sputtering method in an atmosphere of mixed gas of Ar and O_2. PLT file deposited at 580℃ showed perovskite single phase with prominent C-axis orientation perpendicular to the substrate surface. The full width at half maximum (FWHM) of the PLT film was 0.45 degree indicating good crystallinity. From the RHEED observation, the PLT film showed spotty pattern, indication a single crystal phase with rough film surface. The relative dielectric constant(ε_r) and dielectric loss(tanδ) of the perovskite PLT film deposited at 580℃ were 75 and 0.006 at 1kHz, respectively. From the hysterisis loop analysis using sawyer-tower circuit, the remanent polarization(P_r) and coercive field(E_c) were about 10μC/㎠ and 160kV/㎝, respectively.
