This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

The purpose of this study is to increase Academic learning Time -Physical Education(ALT-PE) by analyzing the relationship between the teaching behavior and the learning behavior in middle school physical education classes. The result of this study by recording the 10 randomly sellected teacher'physical education classes with VTR in Phyong tak city area abstracted as fallows. first, in teaching behaviors, teachers allocated class time in the order of monitoring, Management, Lecturing or Orienticipation, Corrective Skill feedback. In a correlation with Academic Learning Time - Physical(ALT-PE), hustle, Positive skill Feedback, Teacher Participation variable have positive correlation. However, Lecturing or Orientation, Naglect, Questioning show negative Correlation. Second, Academic Learning Time - Physical Education(ALT-PE) at middle school pyoung t다 city turn out to be a low 22.62 percent by analying student'behavior phenomenon. This figure is much lower than that of Seoul, Kyunggi, Chungbuk area(37.89) percent by Kim Tae-hyung) and Chungnam area(29.44 percent by Choi jong sun). It means that decreasing the time of Monitoring, Management and lecturing or Orientation makes the time of corrective skill feedback which showered positive correlation with Academic Learning Time - Physical Education(ALT-RE) Increase. In conclusion, teachers should utilize More effcient physical education teaching methods by developing various future-oriented teaching patterns to over come routine monotonous classes. To achieve this goal, teachers should analyze their own classes, use teaching aid materials, implement adequate teaching skill ; methods of drawing more student'attention effciency in class management and roll-calling, rapidness in arranging implements, simple and clear directions. In addition to, we have many problem to solve: insufficients, too many students in class with wating, moveing and non-activity time to be reduce, and so on. Naturally, to increase Academic Learning Time - Physical Education(ALT-PE), it is neccessary that problem above mentioned Will be solved.

Greenhouse industry has been growing in many countries due to both the advantage of stable year-round crop production and increased demand for fresh vegetables. In greenhouse cultivation, $CO_2$ concentration plays an essential role in the photosynthesis process of crops. Continuous and accurate monitoring of $CO_2$ level in the greenhouse would improve profitability and reduce environmental impact, through optimum control of greenhouse $CO_2$ enrichment and efficient crop production, as compared with the conventional management practices without monitoring and control of $CO_2$ level. In this study, a mathematical model was developed to estimate the $CO_2$ emission from soil as affected by environmental factors in greenhouses. Among various model types evaluated, a linear regression model provided the best coefficient of determination. Selected predictor variables were solar radiation and relative humidity and exponential transformation of both. As a response variable in the model, the difference between $CO_2$ concentrations at the soil surface and 5-cm depth showed are latively strong relationship with the predictor variables. Segmented regression analysis showed that better models were obtained when the entire daily dataset was divided into segments of shorter time ranges, and best models were obtained for segmented data where more variability in solar radiation and humidity were present (i.e., after sun-rise, before sun-set) than other segments. To consider time delay in the response of $CO_2$ concentration, concept of time lag was implemented in the regression analysis. As a result, there was an improvement in the performance of the models as the coefficients of determination were 0.93 and 0.87 with segmented time frames for sun-rise and sun-set periods, respectively. Validation tests of the models to predict $CO_2$ emission from soil showed that the developed empirical model would be applicable to real-time monitoring and diagnosis of significant factors for $CO_2$ enrichment in a soil-based greenhouse.

This study was performed to evaluate the mechanical properties of four commercially available veneering resin composites for crown (Dentacolor: DC, Artglass: AG, Esternia: ET and Targis: TG). According to the manufacturer's instructions, disc specimens were fabricated in a teflon mold giving 12mm in diameter and 1 mm in thickness. All specimens were immersed in distilled water at 37℃ for 30 days. An indentation test of 68-degree trigonal diamond pyramid was made under 98.06 mN load for 15 seconds. Hardness numbers, charateristic indentation depths, flow and permanent deformation were measured and compared statistically by ANOVA and Tukey's multiple range test. The results obtained were summarized as follows; 1.The highest hardness value of 87.4 was observed in the ET group and the lowest value of 11.8 was observed in the DC group. Hadness values showed no sinificant difference between the AG group and TG group, but others showed the significant difference beween groups (p<0.5). 2.Flow value of the ET group was significantly lower than those of the AG and TG groups of hybrid composite for crowns. 3.Percent strain during the indentation was the lowest in the DC group and the highest in the AG group, but there was no significant difference in each experimental group (p>0.05). 4.The relationship between the hardness number and flow during the indentation was a negative linear on a logarithmic scale.

The number of workers with noise induced hearing loss which comprise 56.9% in the total number of workers with work-related diseases in Korea of 1994, are becoming in position of the most serious problem. Periodic health examination system which was introduced for health care of workers on hazardous workplace has played important role in health care and the prevention of work-related diseases. The goal of periodic health examination may be obtained when we not only discover occupational disease, but also control them effectively. To study the post-examination health status of workers with noise induced hearing loss diagnosed from 1991 to 1994 in the periodic health examination, all 154 workers in 102 manufacturing factories in Banwol and Siwha industrial complex were reviewed. 1. Among 154 workers, 87 workers(56.5%) were changed to different department, 67 workers(43.5%) remained in the same department. 2. Among 102 workplaces, only 23 workplaces(22.9%) had changed their working environment while 79 workplaces(77.1%) did not. 3. In this study, post-examination health care of the workers diagnosed as noise induced hearing loss had significant correlated with the presence of health care manager, Industrial Health and Safety Committee in workplace and size of industry. The improvement of working environment is also closely related with the presence of health care manager in workplace. 4. Among 154 respondents, 3 workers(1.9%) had received compensation while 151 workers(98.1%) did not. 5. The reasons for not requesting the compensation were that 117 workers(77.5%) were ignorant of the administrative procedure for compensation, 30 workers(19.9%) were not sure of receiving compensation, 4 workers(2.6%) were busy. Considering the result of this study, we must establish the guide of management or contents of post management for noise induced hearing loss. To prevent the noise induced hearing loss, and protect the workers with noise induced hearing loss, education about post management is much required for employer and employee.

조혈모세포이식 환자에서 침습성 진균 감염에 대한 이트라코나졸 액과 플루코나졸 시럽의 예방 효과 : 전향적, 무작위, 비교 임상시험

최수미,이동건,최정현,박선희,엄기성,김유진,김희제,민창기,유진홍,김동욱,이종욱,민우성,신완식,김춘추 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

목적 : 조혈모세포이식 환자에서 호중구 감소 기간 동안 이트라코나졸 액(ITZS)과 플루코나졸 시럽(FCZS)의 진균 감염에 대한 예방 효과를 전향적으로 비교해 보고자 하였다. 재료 및 방법 : 2001년 8월부터 2002년 6월까지 가톨릭 조혈모세포이식센터에 입원하여 동종 조혈모세포이식을 받은 만 18세 이상의 환자들을 각각 ITZS와 FCZS군으로 무작위 배정하여 침습성 진균 감염 발생과 약제 관련 부작용을 전향적으로 조사하였다. 결과 : ITZS군에 40명, FCZS군에 38명이 배정되었고, FCZS군 환자의 평균 나이가 더 많았다. 시험 약제 평균투여기간은 ITZS군 16.4일, FCZS군 21.9일로 ITZS군이 더 짧았다. 이는 ITZS군에서 소화기 부작용으로 인한 약제 중단이 더 많았기 때문으로 보인다. 시험 약제 투여 후 총 빌리루빈 수치의 유의한 증가가 관찰되었으나, 약제 관련 부작용은 모든 환자에서 가역적이었다. 호중구감소 기간동안 표재성 진균 감염은 두 군에서 모두 발생하지 않았고, 침습성 진균 감염은 ITZS군 5명(12.5%), FCZS군 8명(21.1%)으로 FCZS군에서 많았으나, 통계학적으로 유의하지 않았고, 사망률에도 유의한 차이는 없었다. 결론 : 침습성 진균 감염에 대한 이트라코나졸 액과플루코라졸 시럽의 예방 효과에 유의한 차이는 없었으나, 앞으로 더 많은 환자를 대상으로 잘 짝지어진 대조군 연구가 필요할 것으로 보인다. 부작용 중 간독성과 관련하여 이식시 투여되는 여러 약제들과의 상호작용에 대한 연구도 필요할 것이다. Background : Though fluconazole is widely used for antifungal prophylaxis, it is ineffective against mould infections including Aspergillus species. Itraconazole has a broader spectrum than fluconazole but the capsule form shows erratic bioavailability in neutropenic patients. In this study, we compared itraconazole oral solution (ITZS) with fluconazole syrup (FCZS) for the prevention of invasive fungal infection (IFI) in allogeneic hematopoietic stem cell transplant recipients. Materials and Methods : Adults receiving allogeneic hematopoietic stem cell transplantation (HSCT) from september 2001 to June 2002, were randomly allocated to either the ITZS group or the FCZS group. We prospectively evaluated the safety and efficacy of each drug. Results : Out of 78 patients (40 patients in the ITZS group and 38 patients in the FCZS group) who were eligible for this study, 37 patients completed the course of prophylaxis without any evidence of IFI. The mean duration of prophylaxis was 16.4 days for the ITZS group and 21.9 days for the FCZS group (P<0.006). Drug-related adverse events occurred in 28 patients (70.0%) and 19 patients (50.0%) in the ITZS group and the FCZS group, respectively. Common adverse events of ITZS were nausea, vomiting, and diarrhea. Drug-related reversible hepatotoxicity occurred in 4 patients in the ITZS group. There was a significant elevation of total bilirubin level in the ITZS group. The incidence of suspected IFI occurred in 5 patients (12.5%) who received ITZS, compared with 8 (21.1%) who received FCZS (P=0.372). There were no proven IFIs or superficial (oral/vaginal) fungal infections in both groups. Overall mortality was not different between the two groups (2.5% in the ITZS group versus 5.3% in the FCZS group, P=0.610). Conclusion : ITZS and FCZS showed similar protection against IFI during pre-engraftment period. Poor tolerability due to gastrointestinal troubles of ITZS might limit its success as prophylactic therapy. Well matched controlled study with large number of patients will be required in the future.

Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.
