The purpose of this study is to investigate the differences of personality characteristics using Minnesota Multiphasic Personality Inventory(MMPI) by current-smokers, ex-smokers and non-smokers among male high school students. The subjects for this study were 448 first and second year male students at general and vocational high school in Taegu and Kyung-Buk Province. Data was collected from August 25 to September 15, 1999. The instrument used in this study was the Validity Scale and the Clinical Scale, the Ego Strength Scale and the Personality Disorder Scale of the MMPI. The data was analysed by using the SPSS Program which included frequency, percentage, x^2-test, ANOVA, scheffe test and stepwise discriminant analysis. The results obtained from this study were as follows. (1) There were significant differences by smoking behavior groups in parents who smoke and who did not smoke(p=.044), intimate-friends who smoke and not(p=.000), academic record(p=.000), satisfaction with school life(p=.020), effect of smoking on health(p=.000), drinking experience(p=.000), drug-use experience(p=.007) and experience into No minors district(p=.000). (2) T-scores of subjects in this study were in the range of 40-60. Psychopathic Deviate Scale(Pd), Paranoid Scale(Pa), Psychasthenia Scale(Pt), Schizophrenia Scale(Sc), Histrionic Personality Disorder Scale(HST) and Anti-social Personality Disorder Scale(ANT) showed higher T-scores than other Clinical and Personality Disorder Scale. (3) The results of post-hoc in Validity Scale and Clinical Scale are as follows: T-scores of current-smokers were higher than that of ex-smokers and non-smokers in Hysteria Scale(Hy), Psychopathic Deviate Scale(Pd), Paranoid Scale(Pa), Psychasthenia Scale(Pt), Schizophrenia Scale(Sc) and Hypomania Scale(Ma); T-scores of non-smokers were higher than that of ex-smokers in Depression Scale(D), and T-scores of non-smokers were higher than that of current-smokers and ex-smokers in Social Introversion Scale(Si). (4) In Ego Strength Scale and Personality Disorder Scale, T-scores of ex-smokers were higher than those of current-smokers. In Histrionic Personality Disorder Scale(HST) and Narcissistic Personality Disorder Scale(NAR), T-scores of current smokers and ex-smokers were higher than those of non-smokers. In Borderline Personality Disorder Scale(BDL), Anti-social Personality Disorder Scale(ANT) and Paranoid Personality Disorder Scale(PAR), T-scores of current-smokers were higher than those of ex-smokers and non-smokers. In Schizotypal Personality Disorder Scale(STY), T-scores of current smokers were higher than that of ex-smokers. In Avoidant Personality Disorder Scale(AVD), T-scores of non-smokers were higher than those of current-smokers and ex-smokers. (5) As a result of stepwise discriminant analysis of the MMPI Scale by smoking behavior, a discrimination rate of the F Scale, Hypomania Scale(Ma), Social Introversion Scale(Si) and Psychopathic Deviate Scale(Pd) out of the Validity Scale and Clinical Scale was 51.1%, and that of Anti-social Personality Disorder Scale(ANT) and Avoidant Personality Disorder Scale(AVD) out of the Personality Disorder Scale was 51.6%, both of the rates were statistically significant. The Above results suggested that smoking by high school students is related with personality characteristics as well as external factors like family, school and their social environment. So school health professionals who are in charge of school health, should operate various smoking prevention or prohibition programs, taking into account personality characteristics. It might have an effect on smoking prevention and the reduction of the smoking rate.

DW-166HC (^(166)Holmium (^(166)Ho)-Chitosan complex) is a new radiopharmaceutic anticancer agent with a broad anti-tumorigenic spectrum, especially against human hepatic cancer. DW-166HC was evaluated for the appearance of micronucleus in polychromatic erythrocytes (PCEs) of mouse bone marrow cells after subcutaneous arid intravenous single administration. Bone marrow cells were prepared at 24 hr and 48 hr after DW-166HC-I (^(165)Ho-Chitosan complex : cold compound) administration and at 24 hr, 72 hr and 2 weeks after DW-166HC (^(166)Ho-Chitosan complex : hot compound) administration. The results showed there was no statistically significant increase of the numbers of PCEs with micronucleus in all DW-166HC-I administered groups compared with a negative control group but there was statistically significant increase of the numbers of PCEs with micronucleus at 24 hr arid 72 hr in all DW-166HC administered groups, which was recovered after 2 weeks from the drug administration. The results also showed the ratio of normochromatic erythrocytes (NCEs) to PCEs of all DW-166HC-I administered groups was not significantly different from that of a negative controi group but there was significant difference of this ratio at 24hr and 72 hr in all DW-166HC administered groups compared with that of negative group, which was also recovered after two weeks from the drug administration. These results suggested that DW-166HC-I may not cause any chromosomal damage but DW-166HC has in vivo mutagenic potential because of its radioactivity.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

하천에서 분리한 비소 내성세균의 유전적 특성

정미경,이호자 경희대학교 유전공학연구소 1991 遺傳工學論文集 Vol.3 No.-

Arsenite, arsenate에 대해 내성을 가지는 균들을 분리하여 D-3, D-12, D-14로 명명하였고 생리생화학적 검사를 통해 각각 Serratia Iiquefaciens, Klebsiella oxytoca, Klebsiella Pneumonrae로 동정되었다. 내성기작에 관여하는 유전자의 위치 및 분리된 플라스미드의 전이능을 조사한 결과 내성유전자는 플라스미드에 존재하며 내성기작은 전적으로 플라스미드에 의해 조절됨을 알 수 있었고, 또한 conjugative 플라스미드임이 확인되었다. 이에 Klebsiella oxytoca D-12에 존재하는 67 kilobase의 conjugative 플라스미드를 pMH12로 명명하였다. Mitomycin C처리에의해 arsenite 감수성 균주를 선발한 결과 pMH12가 없음이 확인되었다. 분리균주들의 유전적 특성을 규명하기위한 실험에 사용될 marker를 찾아내기 위하여 몇가지 항생물질과 중금속에 대한 내성을 조사하였는데, 특히 D-12의 경우 고농도의 Cd^(2+), Zn^(2+), Hg^(2+)에 대해 내성을 나타내었다. Several arsenic compound-resistant bacteria were isolated from Jung-Rang stream. The isolates, D-3, D-12, and D-14 were characterized phenotypically and genetically, and identified as Serratia liquefaciens, Klebsiella oxytoca, and Klebsiella pneumoniae, respectively. A plasmid of 67 kb was found in Klebsiellu oxytoca D-12 and designated as pMH12. Transfer of this plasmid from D-12 to E. coli HB101 was occurred, and the resulting transconjugant strains expressed the same level of heavy metal resistance as the donor strain. The physical presence of this plasmid in transconjugant was detected with agarose gel electrophoresis. Arsenite-sensitive derivatives of isolate D-12 were obtained with Mitomycin C treatment which cured pMH12. Antibiotics and heavy metal resistances were also examined to be used as a proper marker for the isolates in gene cloning. Isolate D-12 has resistance to several heavy metal ions such as Cd^(2+), Zn^(2+), and Hg^(2+). Also, all the other arsenite resistant isolates showed resistance to several heavy metal ions and antibiotics.

The bogie frames mainly fabricate 9㎜ thick rolled steels and sometimes fatigue cracks occur in their welded joints due to inadequate fatigue design and poor weld quality. The objective of this study is to present the systematic procedure of the fatigue durability estimation and the remaining life prediction for diesel locomotive bogie frame weldments. In order for prediction of remaining fatigue lifetime, service stresses were measured at critical points, using strain gages, during field tests under several rail-roading conditions. It was found that the systematic procedure presented in this study could be applied practically to the fatigue analysis for the locomotive bogie frame weldments.

Fatigue Crack Growth Behavior in Ultrafine Grained Low Carbon Steel

Ho,Kyung Kim,Myung-Il Choi,Chin-Sung Chung Dong-Hyuk Shin 대한기계학회 2002 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.16 No.10

Ultrafine grained (UFG) low carbon (0.15 wt.% C) steel produced by equal channel angular pressing (ECAP) was tested for investigating the effect of load ratio on the fatigue crack growth rate. Fatigue crack growth resistance and threshold of UFG steel were lower than that of as-received coarse grained steel. It was attributed to the less tortuous crack path. The UFG steel exhibited slightly higher crack growth rates and a lower △K_th with an increase of R ratio. The R ratio effect on crack growth rates and △K_th was basically indistinguishable at lower load ratio (R>0.3), compared to other alloys, which indicates that contribution of the crack closure vanishes. The crack growth rate curve for UFG steel exhibited a longer linear extension to the lower growth rate regime than that for the coarse grained as-received steel.<br/>

Recent trend of the development of adhesive has been changed from mass production typed to diversifies small-quantity production type with the growth of automobile and electronics industry. Accordingly, the main purpose of this study is the development of functional hot melt adhesive using polyurethane to improve the conventional hot melt adhesives which have inherent problems against creep and heat resistance. The physical properties and adhesion strength of ethylene-vinyl acetate, polyamide, and polyurethane were compared. The key factor affecting the final adhesion strength was the toughness of adhesive itself and the surface topography of substrate contributed to the increase of adhesion strength.

Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

The big trees have been keeping the relation to human's living way in various aspects, environment protection, emotion creation and tree worshiping through which they believed to be safe, happy and prosperous, and also giving more recreational opportunity to provincial particularly. This study was carried out to analyse the status of designation and management of big tree in Iri-Iksan province, Chollabuk-Do. The result are summarized as follows. 1. It was appeared that at present Big trees in the investigated area were 78 location (7 families, 9 genera, 11 species) that was identified. Among them the species appearing most frequently were Zelkova serrata(25), Salix glandulosa (20), Gingko biloba(15) and Celtis japonica(8) in that order. The order hand, designation grade of big tree classified into six categories, that is 1 botanic natural monument, 5 Si-Kun tree, 3 Eup-Myon tree, 1 maeul tree, 53 Restraint tree ad 15 Non-Designation tree. 2. In designation of nurse tree, there are key needs that are professionals in field survey. We suggested the futher designation plan stressed the importance of the value of big tree. 3. Government have to increase of the forestry staff who take sole charge of the protection of big tree, and must reach managers the technique for effective management of big tree. 4. We have to make an budget of big tree management, establish a protective facilities, control of insets and disease on time, and treat and operate on the injured big tree. Thus government should be positively concerned, and more research would need to understand the critical factors affecting the big tree.
