This study was conducted to evaluate the effects of microbial inoculation on sewage sludge composting. The number and species of microorganisms in sewage sludge sampled on February were higher than those sampled on August. The composting of sewage sludge is inhibited by the polyacrylamide cation, which was used as a coagulant and known to repress the growth of microorganisms. The growth of all microorganisms was inhibited by the addition of the polyacrylamide cation at a concentration of more than 0.8%. The species and viable counts of microorganisms were observed to increase during composting sewage sludge by inoculation of the effective microorganisms and addition of the pine tree sawdust as a bulking agent, compared with those without inoculation. A variety of organisms in compost(sewage sludge plus sawdust) were observed after composting for 30 days, such as Fragilaria sp., Proales sp., Vorticella sp., Schizothrix sp., Anabaena sp., Zoothaminium sp., Epstylis sp., Arcella sp., Balantidium sp., Actinophrys sp., Synedra sp., Euglypha sp., Ulothrix sp., Anacystis sp., and Clostium sp.

본 연구는 정보교육 프로그램이 갑상샘암 수술 환자의 심리 및 신체적 불편감 감소에 미치는 효과를 검정하기 위해 실시된 비동등성 대조군 전,후 시차 설계의 유사 실험연구이다. 자료수집 기간은 2006년 6월 17일 부터 9월 19일 까지 3개월간 이었으며, 연구 대상자는 일개 종합병원에 갑상샘암 수술을 받기위해 입원한 환자 가운데 6월 17일 부터 8월 3일 까지 입원환자 29명을 대조군으로 하였고, 8월 5일 부터 9월 19일 까지 입원환자 30명을 실험군으로 하였다. 연구도구는 심리적 불편감을 측정하기 위해 Derogatis 등(14)이 개발한 ‘자기보고식 다차원 증상목록(Multidimensional Symptom Inven- tory)검사를 사용하였고, 신체적 불편감 측정은 McCorkle & Young(16)이 개발한 도구를 사용하였다. 본 연구의 결과는 다음과 같다; 1) 정보교육 프로그램을 받은 실험군은 정보교육 프로그램을 받지 않은 대조군에 비해 심리적 불편감 정도의 차이는 통계적으로 유의한 차이를 보이지 않았다(p= .135). 다만 ‘근심 걱정’요인에서 유의한 불편감 감소효과를 보였다(p= 0.49) . 2) 정보교육 프로그램을 받은 실험군과 정보교육 프로그램을 받지 않은 대조군은 두군 모두 신체적 불편감 정도가 사후 유의한 수준으로 증가함을 보였다(p= 0.90). 결론적으로 본 연구를 위해 만들어진 정보교육 프로그램은 갑상샘암 수술 환자의 신체적 불편감 감소에는 효과적이지 못하였으나 심리적 불편감의 근심걱정 요인을 감소시키는데는 효과가 있음을 알게 되었다. Objectives: This study was designed as a non-equivalent control group pre and post-test quasi-experimental study to examine the effects of education program using information on the psychological and physical discomfort of patients undergoing operation for cancerous thyroid glands. Methods: The study covered for three months from June 17, 2006 to September 19, 2006. The subjects of this study were selected from those patients who were admitted in one of the general hospitals in order to receive the operation for cancerous thyroid glands. They include 29 control group patients who were hospitalized during the period of Jun 17th to August 3rd 2006, and 31 experimental group patients who were hospitalized during the period of August 5th to September 19th, 2006, respectively. The instruments utilized for conducting this study includes the Multidimensional Self-Report Symptom Inventory test originally developed by Derogatis & et al. (1983) for measuring psychological discomfort. And for measuring physical discomfort, the tools developed by McCorkle & Young (1978) was utilized. Results: 1) Hypothesis 1 “The level of psychological discomfort of the experimental group who completed the information education program would be decreased comparing with that of the control group who didn't complete the program” was partly supported (Worry & Anxiety factor: p= .049). 2) Hypothesis 2 “The level of physical discomfort of the experimental group who completed the information education program would be reduced comparing with that of the control group who didn't complete the program” was not supported (p= -.90). Conclusion: The information program provided for this study was proved to be not effective for decrease physical discomfort of the patients undergoing operations for cancerous thyroid glands but proved to be effective for decrease the anxiety factor of psychological discomfort.

Objectives: This study is a descriptive research designed to provide basic materials for developing clinical nurses' ability to make more active observation and correct report of cancer patients' pain for advanced pain palliation by examining their knowledge of cancer patient's pain and pain-palliation. Method: Data were collected from 247 clinical nurses serving for the Veterans general hospital in Gwangju and Daegu City from Sep. 1 to 15, 2005. Results: 1. Average rate of correct answer on pain was 79.88% and that of knowledge on pain-palliation was 56.80%. 2. Difference in knowledge of pain-palliation by general characteristics showed statistically significant difference in clinical nursing experience of cancer patients (t=1.978, p=.049) and type of degree (F=5.380, p=.005) 3. As a result of comparing knowledge of pain depending on presence and absence of experiences of pain-palliation education, scores of group without having pain education (t=-3.130, P=.002) were higher and statistically significant. 4. As a result of comparing knowledge of pain-palliation depending on presence and absence of experience of pain-palliation education, scores of group having pain education (t=2.049, p=.042) were higher and statistically significant, Conclusion: Accordingly, this study finds out that educational contents of cancer patients' pain showed no difference in knowledge level between the groups with and without education and thus a new program which has new content and new approach for education on pain and pain- palliation knowledge in cancer patients is needed.

Objectives: This study examines the degree of concern experienced during plasma-donation among university students who visited the blood-donation house located in two universities in Gwang-ju City to donate blood-plasma by grasping the variables affecting concern in order to provide basic data establish needed nursing intervention for donator of blood plasma. Method: The subjects of this study were 184 university students and the data were collected by self-reported Questionnaire given 10 minutes after the donation of blood plasma. Period of data collection was from Jul. 1st to Aug. 30th 2003. Results: Total concern mean was 2.29 and for the Question 'When nurse seemed lacking blood collection skill' showed the highest point and the mean as 3.11 and 'Would there be problem in health condition after blood-donation because the amount of donated blood is too much' showed the lowest mean as 1.86. Female students showed higher concern score as 38.74±8.47 than male students as 31.94±9.14 and there was significant difference(t=-5.08, p=.00). The degree of concern showed significant difference in frequency of blood donation(f=5.31, p=.00) and as Scheffes post-test, there were significant differences in '1-5times donated group'(37.32±9.49). For the Question of 'what the most inconvenient matter in plasma-donation', the group answered 'no' for 'it took long time comparing with previous whole blood-donation' was 35.58±9.51, and it was higher than 'yes' group(mean 32.68±9.20) and there was significant difference(t=-2.07, p=.04). Among concern characteristics according to the symptoms blood-plasma-donation, 'sleepy, tired' answered group's mean was 36.61±9.32 and it was higher than that of group answered 'no' for the question 33.36±9.40 and there was significant differencdt=2.19, p=.03) Answered 'got bruise' was 38.36±8.69 and it was also higher than that of group answered 'no' as 33.45±9.43 and there was significant difference(t=2.96, p=.01) The group answered 'no abnormality after blood-plasma-donation' was 36.03±9.33 and it was higher than that of group answered 'yes' for the same question as 32.34±9.30 and there was significant difference(t=-2.67, p=.01). The level of concern according to the nurses' kindness, after Scheffes post-test, there were significant differences between 'kind' group(36.24±8.l4) and 'very kind' group(29.73±10.35), and between 'moderate' group(38.28±9.29) and 'very kind' group(29.73±10.35) (f=7.90, p=.00). Conclusion: The concern level during plasma-donation in university students was showed the most high 'when nurse seemed lacking blood collection skill'. So in order to decrease the level of plasma donator's concern, the nurses must try to increase collecting skill of blood and try to show kindness to the plasma donators also.

정신분열병과 N-Methyl-D-Aspartate 수용체 유전자와 연관된 VNTR 표지자인 D9S158 다형성의 연합

김종원,채영규,정은기,김길숙,박강규,이영호,최인근,양병환,한진희 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.5

정신분열병과 NMDA 수용체와 연관된 D9S158 유전적 표지자와의 연관성을 알아보기 위해 75명의 정신분열병 환자군과 87명의 정상대조군을 대상으로 중합효소연쇄반응을 이용하여 연합연구를 시행하여 다음과 같은 결론을 얻었다. D9S158 유전좌위에는 모두 8개의 대립유전자가 있었고, 각 대립유전자는 cytosine-adenine염기가 반복되는 217염기쌍에서 233염기쌍의 형태였다. 먼저 정신분열병 환자와 정상대조군의 대립유전자의 빈도를 비교해 본 결과 통계적으로 유의한 차이를 보이지 않았다(p〉.05). 환자군을 좀 더 동질적으로 만들기 위해 정신분열병의 가족력 유무, 음성 및 양성증상, 연성신경학적 징후, DSM-IV 임상아형에 따라 환자군을 나누어 대립유전자의 빈도를 비교해 본 결과, 특정 임상양상과 관련이 있는 대립유전자를 발견하지 못하였다. 결론적으로 본 연구에서는 D9S158 유전좌위와 정신분열병의 연관성을 입증하지 못하였으나 NMDA 수용체 유전자주위의 다른 표지자나 좀 더 유전적으로 동질한 환자군을 대상으로 한 추후연구가 필요할 것으로 생각된다. An association study with Korean schizophrenic patients(N=75) and normal controls(N=87) was performed to find the relationship between D9S158 polymorphism and schizophrenia using polymerase chain reaction. Eight different alleles of a dinucleotide polymorphism on D9S158 locus were observed in both group. When we compared the frequencies of alleles between schizophrenics and normal controls, there was no significant difference between two groups. To increase homogeneity of schizophrenic group, we divided schizophrenic group by clinical phenotypes such as family history, negative and positive symptoms(PANSS), soft neurologic signs(NES-K) and DSM-IV diagnostic subtypes. Then we compared the frequencies of alleles among subgroups of clinical phenotypes, and there were no significant differences between subgroups(p〉.05). Although our findings fail to provide an evidence of association between schizophrenia and D9S158 locus, further investigation of other loci that are linked to NMDA receptor gene may be needed in genetically homogeneous subgroups of schizophrenia.
