Background : 6.1% of red blood cells and whole blood issued to the operating room was not transfused to the patients and discarded in Seoul National University Hospital in 1994. Objectives : We planned to set up an effective management program of blood in the operating room and we investigated whether this program could reduce the disposal rate of blood. Methods : We made a guideline of blood management in the operating room through a workshop. The guideline was revised after a preliminary application. The revised guideline was applied for 5 months from May to September in 1996. The disposal rate was compared before and after the installation of the new program. Results : 5,336 units of blood were issued to the operating room for 5 months. Disposal rate of red blood cells and whole blood was markedly reduced from 6.2% in May to 2.1% in September(p<0.05). The average disposal rate was 3.7% during the five months. Conclusion : We were able to reduce the disposal of unused blood in the operating room through the development and the application of a new blood management program.

서울지하철 1~4호선을 운용중인 서울메트로의 2012년도 수송인원 및 운수수입 실적을 2011년도와 대비하여 분석한 결과 수송인원 0.3%, 운수수입 13.4%가 증가하였다. 수송인원 증가 요인은 승객의 유입, 강설 등이 있었고, 운수수입은 2012.02 운임인상에 따른 결과이다. 호선별 수송인원은 1,4호선이 0.9~1.6% 감소한 반면, 2,3호선은 0.4~0.8%가 증가한 것으로 나타났다. 한편, 서울메트로는 1974.8 개통 이래 38년 동안 총 인원 383억명을 수송하였다. 이는 1~4호선 차량을 전세계 인구 70억명이 1인당 6회 정도 이용한 것이다. When We were analyzing transportation personnel and fare income result of seoulmetro line 1 to 4 in 2012, transportation personnel have increased 0.3% and fare income have increased 13.4% over a year ago. The reasons for the inceased transportion personnel are passengers growth and snowfall, and the increase of income is due to fare impression. Transportion personnel are decreased 0.9~1.6% in line 1, 4, but are increased 0.4~0.8% in line 2, 4. Meanwhile, Seoulmetro carried a total number of 383 billion passengers over 38 years since 1974. 8. This number means that 70 billion whole world populations used six times per one person.

본 실험은 딸기의 고설수경재배에 이용 가능한 적정한 배지를 조사하기 위하여 수행하였다. 코코피트 배지에서 엽수가 가장 많았으며, 원예용 상토배지에서 엽장과 엽폭이 가장 우수했다. 과중은 통계적인 유의성은 없었지만 원예용 상토배지에서 25.8g로 가장 높게 나타났고 과장, 과경, 당도 등도 처리 간에 유의한 차이는 없었지만 원예용 상토배지에서 가장 좋은 결과를 나타내었다. 주당 수확과수는 원예용 상토와 코코피트 배지 모두 왕겨 혼합배지보다 유의하게 높은 수치를 나타내었다. 주당 수량은 원예용 상토배지가 545.9g으로 가장 많았으며, 그 다음으로 코코피트 배지에서 높았으며 왕겨 혼합배지에서 가장 낮았다. 본 연구에서는 딸기의 수경재배에 적합한 고형배지로서 생산자가 구입과 작업이 편리하고 물리성이 좋은 원예용 상토의 우수성을 입증하여, 딸기 재배농가에게 유용한 정보로 활용될 수 있을 것으로 기대되며 타 작물의 고형배지 재배에서도 유용하게 이용될 것으로 생각된다. The experiment has investigated the effects of growth, yield, and fruit quality of strawberries by three different kinds of substrates. Commonly used media cocopeat, cocopeat mixed with rice hulls and compound nursery media were used to select a proper medium by comparing growth status, yield and fruit quality. Number of leaves was most in cocopeat substrate, and leaf length and leaf width were highest in compound nursery media. Fruit weight was heaviest in compound nursery media, but there were no significant statistical differences in fruit length, fruit width and soluble solids of fruit. Number of fruits per plant was much in compound nursery media and cocopeat than cocopeat mixed with rice hulls. The most yield per plant was in compound nursery media and the least it was in cocopeat mixed with rice hulls. The results of this experiment will be utilized in the new substrate application for strawberry hydroponics.

Urinary retention is a common complication after abdominal surgery. Urinary retention causes infection and damage to the urinary system, prolonging hospital stays and increasing health care costs in the end. Because medical personnel tend to regard urinary retention as not being a serious problem, it is hard to find any method which decrease the postoperative urinary retention. There are few papers reporting the incidence and the factors which influence the postoperative urinary retention. The purpose of this study is to evaluate the incidence of postoperative urinary retention and to identify the factors which affect the postoperative urinary retention. We retrospectively reviewed 296 patients out of 338, who had been undergone laparotomy under spinal or general endotracheal anesthesia during a three-month period from January to March 1998. We reviewed nursing, anesthetic and operative records. Among the 296 patients, male were 189(63.9%) and female were 107(36.1%). Postoperative urinary retention occurred in 71 patients(24%). The incidence rate was higher in female patients than in male (M : F=18% : 35%). Factors that influence the incidence of postoperative urinary retention were sex, duration of operation, the amount of fluid given the patient, preoperative history of dysuria, and preoperative insertion of a urinary catheter. Among those factors, preoperative urinary catheter insertion is the most effective preventive measure in lowering the incidence of postoperative urinary retention (Spearman correlation coefficient, r=-.462). Shortening the operation time and sparing the fluid which is infused during operation are important in preventing postoperative urinary retention. Preoperative urinary catheter insertion may be helpful in lowering urinary retention in those patients who have a possibility of postoperative urinary retention.

임승화,조문수,최경숙 성인간호학회 1997 성인간호학회지 Vol.9 No.1

Although there are many peri-operative measures to reduce core temperature loss during operation, rapid drop has been experienced in the first sixty minutes following induction of general anesthesia. Recently, preoperative warming has been emphasised to prevent inadvertant hypothermia during operation. The purpose of this study is to find the effect of preoperative warming on reducing rectal temperature drop in surgical patients. With informed consent, 46 female adult patients scheduled for total abdominal hysterectomy or salpin-go-oophorectomy in the Seoul National University Hospital from September 3, 1996 to September 19, 1996 were divided into two groups. The variables of age and body surface were matched between the two groups as possible. Among them, 24 patients were preoperatevely covered up to the shoulders with a forced-air warming blanket(WARM TOUCH™). set between 36-40℃ for prewarming, and the other 22 patients(control group) were not before the induction of anesthesia. Rectal temperature was measured by mercury thermometer for rectum after admission to the operating room and by rectal probe which was inserted in the rectum just before the induction during the operation. The rectal temperature was monitored and recorded at every fifteen minutes for the first sixty minutes after the induction and each step during the surgery(intubation, surgical draping, peritoneum opening, one hour and the end of the operation) Collected data were analyzed by means of t-test, Repeated Measures Analysis of Variance with PC-SAS. The results of this study are as followings. ① There was no significant differece between the two groups in age, weight, height room temperature, basal rectal temperature, opration time. ② Temperature gradient of the rectal temperature in the warming group was less steeper than that in the control group during the first sixty minutes after general anesthesia. ③ The rectal temperature measured at every fifteen minutes for the first sixty minutes and the end of surgery after the general anesthesia showed the difference between the two groups during surgery. ④ There was no rectal temperature difference during the intubation, however there was significant temperature difference between the two groups from draping to the end of surgery. In conclusion, prewarming of the surgical patient before induction resulted in increased the skin temperature and heat content, which relieved the dangerous core temperature drop which is potential to be provoked within one hour after induction of the surgical patients and kept the rectal temperature higher than that of the control group during surgery. The suggestions from this study are shown below:First, further study is needed to find the preventive effect of the core temperature drop in the first sixty minutes after anesthetic induction by preoperative warming for gastrorectal, thoracic surgery patients who may have the core temperature drop during the operation. Second, in other to keep patient normothermia during the surgery, it needs to study whether using pre-and peri-operative warming can prevent hypothermia or not. Finally, the study of the preoperative warnimg effect on surgical patients' relaxation and thermal discomfort before the operation is needed because most patients in the case group said to have felt thermal comfort :'comfortable' and 'good'.
