This study was performed to evaluate the actual temperature rise on the surface of Buchanan plugger using thermocouple. The heat carrier system 'System B Heatsource'(Model 1005, Analytic Technologies, Redmond, WA, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ on digital display and the power level on it was set to 10. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 mm increments from the tip to the 4 mm length of shank. The heat control spring was touched for 5 seconds, and temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01 using Data Logger. The data were statistically analyzed by one-way ANOVA. The results were as follows. 1. The position at which the temperature peaked was approximately at 1~2 mm far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F plugger and followed by, in descending order, FM plugger, M plugger. ML plugger showed the lowest peak temperature (p<0.01). 3. The temperature on the pluggers was decreased with the increase of touching time. This results suggest that the actual temperature on the surface of the pluggers dose not correlate well with the temperature set on digital display. Heat concentrates around the up. The larger plugger reveals lower temperature rise relatively.

The flaws detected at the steam generator tube of the Nuclear Power Plant are the wear indications by anti-vibration bars and circumferential cracks at the top of the tubesheet. It is easy to detect and size wear indications. Also the wear indications are commonly found at the steam generator tubes. However, the steam generator tube which includes crack indication is plugged because it is very difficult to predict the growth rate and the sizing error is high. The motorized rotating pancake coil has been used for the detection of circumferential crack since it is not possible to detect using the conventional bobbin probe. This paper describes the characteristics for the circumferential crack at the steam generator tubes of the Korean Standard Nuclear Power Plants.

This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource' (Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200 which Dr. Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 ㎜ increments from the tip to the 4 ㎜ length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2㎜ far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by, in descending order, FM type, M type. ML type showed the lowest peak temperature (p<0.01). This results suggest that the actual temperature on the surface of the pluggers does not correlate well with the temperature set on digital display. Heat concentrates around the tip. The larger plugger reveals lower temperature rise relatively.

In this study, using the extinctive composting apparatus, it took a day for the degradation of waste food with high temperature and aerobic condition. It was confirmed by the change of organic ratio, condensed water, and weight. Final production included rare organic ratio so that it was easy to degrade microorganism but it was not enough pH and salt for using compost. During reaction, condensed water was produced about 20 ℓ/day, the eighty percent of waste food was degraded by compositing reaction on the basis of weight, therefore, this means that it is go effective on the volume reduction.

김찬우,이동건,강승훈,조지현,이수진,조동환,김정기 대한생물치료정신의학회 2003 생물치료정신의학 Vol.9 No.2

Objectives : Risperidone and olanzapine, which are atypical antipsychotics. are widely used in the treatment of schizophrenia as the 1st line drug, proving their effectiveness for both positive and negative symptoms. They also have many advantages even from the side effects. However, they show differences with the chemical structure and pharmacokinetics and they work differently to receptors. Researchers have studied the effect and side effect during the acute phase of schizophrenia as an open prospective study. Methods : Forty subjects with DSM-IV schizophrenia or schizoaffective patients including 1) 1st onset schizophrenia patient, 2) patient who has been treated by the prior antipsychotics and not improved or even worse to be admitted again, were assigned to receive risperidone or olanzapine for 6 weeks. Psychopathology, adverse effect. weight change, fasting serum glucose, and drug cost were compared within and across groups. Results : After 6 weeks later both treatment groups showed the significant decrease in PANSS positive, general psychopathology and total score while they did not show any significant difference between two groups. Risperidone group, however. showed the significant decrease in PANS negative score, which olanzapine group did not. In terms of adverse effect risperidone group showed more extrapyramidal symptom than olanzapine group. Body weight rised significantly after Gweeks, but no significant difference between two treatment groups. There were no significant indrease of fasting serum glucose level. Conclusions : Risperidone and olanzapine are effective drugs which can be used during the acute phase of schizophrenia. Risperidone is expected to shorten the admission day and remission of the symptom of acute phase, mile olarizapine is more advantage in a neurologic side effect than rispendone.

벼, 콩, 상치, 당근, 호박의 가식부위에 대하여 몇가지 토양에 있어서 토양-작물체간 Mn-54, Co-60, Zn-65, Cs-137의 전이계수를 포트 재배에 의한 방사성 추적자 흡수실험을 통하여 조사하였다. 핵종간 전이계수는 거의 모든 경우 Zn-65>Mn-54>Cs-137>Co-60의 순이었다. 콩이 벼보다 전반적으로 한 자리 정도 높은 값을 보였고 채소류의 경우에는 대체로 상치에서 가장 높고 호박에서 가장 낮은 값을 보였다. 강산성 토양에서는 약산성 토양에서보다 전이계수가 훨씬 높았다. 본 조사결과에 입각하여 한국인의 섭식경로 피폭선량 평가에 이용하기 위한 각 핵종의 전이계수치가 작물별로 제안되었다. Soil-to plant transfer coefficients of Mn-54, Co-60, Zn-65 and Cs-137 were estimated for the edible parts of the rice, soybean, lettuce, carrot, and squash grown in different soils by radiotracer uptake experiments using pot cultures. The transfer coefficients of radionuclides were n the order of Zn-65>Mn-54>Cs-137>Co-60 in most of the cases studied. The coefficients for soybean were roughly and order of magnitude higher than those for rice. Among vegetables, lettuce mostly showed the highest value and squash, the lowest. In the strongly acidic soils. From the data obtained, crop-specific transfer coefficients of the four nuclides were proposed for the use in Korean food-radiation dose assessment.

Tetrodotoxin is a neurotoxin produced by about 90 species of puffer fish and causes paralysis of central nervous system and peripheral nerves by blocking the movement of all monovalent cation. Ingestion of tetrodotoxin produces clinical manifestations such as paresthesias(within 10-45 min), vomiting, lightheadedness, salivation, muscle twitching, dysphagia, difficulty in speaking, convulsion and death that expressed by cardiopulmonary arrest with loss of brain stem reflex sometimes. Tetrodotoxin prevents or delays ischemia induced neuronal death by way of following 3 mechanisms. Firstly, it reduces the energy demand of the brain tissues. Secondly, it delays or even prevents anoxic depolarization. Finally, it deminishes ischemia induced cell swelling and cerebral edema. We report a case of puffer fish poisoning which presented with cardiopulmonary arrest and loss of brain stem reflex, but completely recovered by aggressive cardiopulmonary resuscitation.
