There exists a major impediment to learning electricity which may illuminate why direct presentation of scientists' ideas is too aggressive a strategy. This impediment lies in thinking that electricity is used up and in envisaging the light bulb as a consumer. This view is based on a powerful idea which summarises much of our experience; it declares that 'things get used up', 'you cannot get something for nothing', and 'intuitive thinking'. To replace this view with scientific view, we made the analogy model. It is suggested that the analogy model is more effective in teaching electricity circuits than conventional teaching method.

남궁기,조현상,김병천,현명호,안혜리,이희상,유계준 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.5

목적 및 방법 : 본 연구에서는 알코올 의존으로 진단된 남자 환자 75명을 대상으로 MMPI 점수를 이용하여 군집 분석으로 아형 분류를 시도한 후, 사회인구학적 특성과 음주와 관련된 변인으로 그 분류가 판별 타당성이 있는지를 알아보았다. 결 과 : 군집 분석 결과 전체 대상은 6(Pa)-7(Pt)-8(Sc) 프로파일의 정신병적 아형(21.4%), 2(D)-3(Hy)-1(Hs) 프로파일의 신경증적 아형(49.3%), 그리고 정상 프로파일 아형(29.3%)의 세 아형으로 분류되었다. 이 세 아형간의 연령, 학력, 결혼 상태, 음주로 인한 입원 경력, 주당 평균 음주 일수, 음주시 평균 음주량, 음주 시작 연령, 직계가족상의 알코올리즘의 가족력 유무의 차이를 비교한 결과 통계적으로 유의한 차이는 없었다. 결 론 : 본 연구의 결과는 통계학적으로 유의한 세 아형으로 분류되었으나 이 아형 분류가 판별 타당성을 갖추지 못했음을 시사한다. Obects & Methods : The authors tried to classify 75 male patients with alcohol dependence by using cluster analysis of their MMPI data, to identify the characteristics of each subtype classified through that process and to evaluate the discriminant validity of the classification. Results : The subjects were divided into 3 subtypes by K-means cluster analysis of MMPI scores : a psychotic subtype of 6(Pa)-7(Pt)-8(Sc) profile(21.4%), a neurotic subtype of 2(D)-3(Hy)-1(Hs) profile(49.3%), a normal subtype(29.3%). But, there were no statistically significant differences of age, educational level, marital status, admission history due to alcoholic problems, number of drinking day per week, average amount of ethanol consumed per drinking occasion, age at onset of drinking and family history of alcoholism among these three subtypes. Conclusion : It seems that the subjects with alcohol dependence could be classified into three subtypes with statistical significance, but this statistical classification does not constitute any evidence of discriminant validity.

유제복,장희정,김남초 성인간호학회 2003 성인간호학회지 Vol.15 No.4

Purpose: This study was designed to investigate the survey of analyzing nursing interventions and nursing outcomes of the patients with liver transplantation. Method: The subjects of this study consisted of 83 patients and fifteen nurses who took care of them. The methods of this study were retrospective and descriptive survey. Result: The mean age of patients was 42.7 years and the subjects were 62.7% males. 56.7% of these patients were diagnosed with liver cirrhosis of B type. The mean duration of hospitalization was 48.6 days. Ninety-five nursing interventions were performed at least daily. The most frequent used interventions were "environmental management: comfort", "medication administration: parenteral", "cough enhancement", and " oxygen therapy". Even though SGOT level to identify nursing outcomes was decreased, SGOT was not within normal limits. Therefore, even after discharge of patients. There is a need to take care of them carefully. Conclusion: These findings revealed the significance and need of nurse practitioners who performed professional nursing intervention for the patients with liver transplantation. Especially, it is necessary needs to develop the nursing intervention programs for comfort.

禾穀類 種子 發芽時 호분층과 ??組織의 細胞壁에 多量 含有되어 있는 (1-3, 1-4)-β-glucan을 分解하여 種子의 發芽에 必要한 加水分解酵素의 分泌 및 擴散 浸透를 돕는다. 本 硏究에서는 國內 麥酒麥의 (1-3, 1-4)-β-glucanase 遺傳子의 構造 및 發現 에 대한 基礎 情報를 얻기 위하여 生化學的 및 分子生物學的 方法을 利用하여 發芽種子 및 어린 잎에서의 酵素活性과 遺傳子의 發芽樣狀 그리고 遺傳子의 構造 等을 調査하였다. 麥酒麥 發芽種子中 (1-3, 1-4)-β-glucanase 活性은 發芽 7日째에 제일 높았다. (1-3, 1-4)-β-glucanase의 活性測定에 使用한 (1-3, 1-4)-β-glucan이 (1-4)-β-glucanase에 의해 分解될 可能性이 있으므로 (1-4)-β-glucanase의 活性도 測定하였는데 (1-4)-β-glucanase의 活性이 매우 낮게 나타나서(1-4)-β-glucanase가 (1-3, 1-4)-β-glucanase을 分解하여 (1-3, 1-4)-β-glucanse의 活性에 影響을 미쳤을 可能性이 매우 낮았다. 麥酒麥의 (1-3, 1-4)-β-glucanase 遺傳子 構造를 PCR을 利用하여 調査하였던바 國內 麥酒麥의 (1-3, 1-4)-β-glucanase 遺傳子 構造는 外國의 다른 品種들이나 귀리의 遺傳子 構造와 대단히 類似하였다. 酵素活性 測定과 귀리의 (1-3, 1-4)-β-glucanase cDNA clone을 ?識子로 利用한 보리의 mRNA 分析에 의해서 發芽傳子 및 어린 잎에서 (1-3, 1-4)-β-glucanase가 種子發芽 以外에도 生育中인 組織細胞의 伸張과 發育 및 β-glucan 再利用에 泌要한 β-glucan 代謝에 關與하고 있음을 示唆하는 結果라 생각된다. (1-3, 1-4)-β-glucans hydrolysis of cell wall (1-3, 1-4)-β-glucanas accompanies degradation of endosperm cell walls during cereal seed germination. To investigate (1-3, 1-4)-β-glucanase expression pattern in Korean malting barley, (1-3, 1-4)-β-glucanase activity, gene structure and mRNA expression patterns werre examined. (1-3, 1-4)-β-glucanase activity increased as germination proceeded and the highest enzyme activity was detected in seeds germinated for 7 days. Because (1-4)-β-glucanase have a potential to degrade (1-3, 1-4)-β-glucans, (1-4)-β-glucanase activity was also determined. (1-4)-β-glucanase activity, however, was very low minimizing possibility of (1-4)-β-glucanase action on (1-3, 1-4)-β-glucan substrate. PCR technique was employed to investigate (1-3, 1-4)-β-glucanase gene structure. The amplification product of the expected size from the targeted sites of Dusan #29 indicated that (1-3, 1-4)-β-glucanase systems were conserved in different barley varieties and even in oats. (1-3, 1-4)-β-glucanase activity and mRNAs were detected in young leaves as well as in germinating seeds. This may suggest that (1-3, 1-4)-β-glucanase are also involved in β-glucan metabolism required for cell elongation and β-glucan reutilization during leaf growth and developmetn.

강남미,유경희,김성재,조남옥,최희정 서울대학교 간호대학 간호과학연구소 1996 간호학 논문집 Vol.10 No.1

This study was conducted by critical review analyzing literatures of theories focused on changes of health behaviors. 5 theories-TRA, HBM, Self-Efficacy, Social Support, and Locus of Control-were selected among many theories of health behaviors. Theories were summarized, and models and concepts of theories were described. The results of this study were follows : 1. health behaviors could be classified into preventive behaviors and curative behaviors. 2. Most conceran of previous studies in this field was on health behavior execution itself or on its outcome. 3. the focus of previous studies was on initiation, maintenance, facilitation, and change of preventive and curative behaviors. 4. Factors affecting on health behaviors were demographic factors as exogenous variables and intrapsychic and extrapsychic factors as endogenous variables. 5. Previous studies tested predictability and explicability of these theories onhealth behaviors and identified factors affecting health behaviors most. 6. concepts of TRA, SELF-Efficacy, and Social support had higher explicability on health behaviors than concepts of HBM and Locus of control. From results of this study, we suggested the direction and considerations for futher nursing studies related with these theories. And we derived testable propositions from relationship between concepts and each others.

뉴질랜드의 종자품질관리체계와 향후 우리나라의 품질관리 개선 방향

김진기,유남희,나의식 한국국제농업개발학회 2001 韓國國際農業開發學會誌 Vol.13 No.4

뉴질랜드의 종자산업은 종자개량, 품종보호, 종자생산, 종자검사, 종자보증 및 종자교역 등 여러분야의 연구와 실무를 통하여 종자품질관리에 선구적 입장을 유지하여 왔으며 신품종의 개발과 합리적인 증식 및 관리체계를 통하여 양질의 종자공급능력을 발전시켜 왔다. 1970 년대 이전까지는 품종개량 및 종자품질관리는 정부주도로 이루어졌으나 현재는 정부가 직접적인 관여에서 점차 간접적인 위임형태로 바꾸어 종자품질관리 관련 업무 일부만 남기고 모두 민영화가 추진되었다. 위임받은 업무에 대한 책임은 위임받은 조직이 지며 정부는 품질관리 체계를 정기적으로 감독하고 감시하는 자세로 전환하였다. 이와 같은 변화에 따라 종자품질관리체계의 하부조직은 대부분 독립적인 예산체계를 구축하였고 업무도 좀 더 독립성을 갖게 되는 효과를 보았다. 그러나 계속적인 정부 지원의 절감과 새로운 조직의 지나친 상업적 운영은 전문인력이 점차적인 감소와 연구개발활동의 축소라는 부작용도 있다. 우리나라의 종자산업발전을 위하여 공공기관이나 민간종묘회사 어느 쪽이든 품종개량과 종자품질관리활동이 활발하게 이루어져야 할 것임은 말할 것도 없다. 그러나 앞으로 국내 종자시장의 변화나 재정적인 이유로 품종개량과 종자품질관리체계에 어떤 개선이 요구된다면 뉴질랜드가 재정적인 동기에서 도출하였던 공공기관의 기능과 역할의 분담조정, 인력의 조직화와 민간종묘회사의 참여방식 및 종자의 상품화 체계구축 등 선험적 체계가 다소라도 참고가 되지 않을까 생각된다. New Zealand has developed a very efficient seed quality control scheme. In New Zealand, cultivars are now developed under contract to the CDMU(Cultivar Development and Maintenance Unit) of AgResearch(NZ Pastoral Agriculture Research Institute Limited). MAF (Ministry of Agriculture and Forestry) is empowered to provide seed certification services, and the scheme is administered by MAF Quality Management using procedures that are in accordance with OECD standards. New Zealand has no seed laws and participation in the seed production industry is entirely voluntary. although participants must adhere strictly to the rules and procedures involved. National Seed Laboratory (NSL) has played a central role in prividing seed quality assessment. Recently all sectors of the seed industry in New Zealand have been reformed and become more commercialized with users-pay policy. The services have been affected by moves to reduce government involvement in its affair and to eliminate government subsidies. However, this has led to reduction of research activities and personnel in seed technology. The future directions of seed quality control system in Korea could refer to New Zealand scheme.

This study was conducted to investigate the seasonal changes of inhibitors during after-ripening of the ginseng seeds. The bioassays of lettuce seed germination rate to the water and chlorogorm soluble fraction extracted from ginseng seeds during stratification were applied. The obtained results were summarized as follows: 1. Three kinds of germination inhibitors were detected in the water soluble fraction of the after-ripening seeds, and the activity of inhibitors was more increased at the Rf 0.1 zone than that of the Rf 0.4-0.5 and 0.8-1.0 zone. 2. Chroloform soluble fraction showed the similar tendency to the water soluble fraction, and promoter was recognized at the Rf 0.1-0.2 zone in the seeds of 90th day after stratification. The inhibitor of the Rf 0.1-0.2 zone increased in accordance with stratification, and that of the Rf 0.9-1.0 zone decreased slightly. 3. On the whole, the physiological activities of three kinds of germination inhibitors from the water soluble fraction showed more increase than those of the chloroform soluble fraction. 4. The water and chloroform soluble 'faction from the embryos of ginseng seeds during stratification showed two kinds of germination ingibitors at the Rf 0.4-0.5 and 0.9-1.0 zones, and water soluble fraction from the endosperms of ginseng seeds showed three kinds of inhibitors at the Rf 0.1-0.2. 0.4-0.5 and 0.7-1.0 zones.

Precipitation was formed during the preparation of decoction from mixure of Scutellariae Radix and Coptidis Rhizoma or Phellodendri Cortex according to the prescription of Hwang-ryean-hae-dog-tang. Baicalin and berberine, the active ingredients of the two herbal medicine were identified in coprecipitated product. Pills were prepared using the coprecipitated product and various binders. The dissolution rate of baicalin and berberine from pills was increased in at pH1.2 when acacia or tragacanth was used. The absorption rate of baicalin from the coprecipitated product was raster than the from Scutellaria extract, but the absorption of berberine from CPP was slower in stomach, duodenum and jejunum of rats compared with Coptis expract. The time equired for the maximum serum concentration (Cmax) of baicalin and berberine from CPP in mice were 150 and 200 min after oral administration. respectively. The maximum serum concentration of baicalin from CPP in mice was higher than Scutellaria extract, but the concentration of berberine was lower compared with Coptis extract. The minimum inhibitory concentration of CPP was below 50 ug/ml against gram positive bacteria, and was higher than that against gram negative bacteria. The antibacterial activity of CPP was lower than the of berberine.but was more potent than Scutellaria extract. It was found that the ingibition rates of growth by CPP against S. cpidermidis, K. pneumoniae, B cereus and S. aureus were 60.1, 5.11, 45.4, and 39.9%. respectively.

서영숙,김유미,남문희,강성홍,임지혜 한국의료QA학회 2009 한국의료질향상학회지 Vol.15 No.1

Background : The principal diagnosis has been used in many different fields such as hospital statistics, medical research, insurance claim, national health statistics and so on. Some principal diagnoses have a relatively low level of reliability in the medium-sized hospitals. The purpose of this study is to identify the reliability level of principal diagnoses and to suggest ways to improve reliability of the principal diagnosis. Method : Data were collected from a medium-sized hospital located in Pusan. The discharge summaries on 323 patients who were discharged in January, 2008 and the outpatient summaries on 251 patients who visited the hospital on March 28, 2008 were collected, and descriptive analysis was performed using SPSS version 12.0K. Result : The findings are the followings: (1) the diagnostic consistency rate between medical records and doctors’ was 92.0%; (2) the diagnostic consistency rate between medical records and insurance claims was 86.1%; (3) the diagnostic consistency rate between doctors’ diagnoses and insurance claims was 80.2%. The evidence seems to indicate that some principal diagnoses have reliability problems in the medium-sized hospitals. Conclusion : The results of this study suggest the followings: (1) employees should be trained and supervision of hospital activities are needed; (2) network systems should be constructed for each department; (3) professions need to be fostered (4) doctors’ awareness of medical records should be changed.
