Recently, the robustness against daily impact is important according to portablization and downsizing of mobile electronics. Especially, almost parts of cellular phone should undergo drop test when they fall 1.5 m above ground. This test simulates the case when cellular phone slips through user's fingers while he is talking on the phone. This paper studies a drop test of auto focusing (AF) actuator for camera module in cellular phone. This component is composed of voice coil motor (VCM) as an actuator and leaf spring as a guide and suspension. The leaf spring's deformation is essential for the test because its permanent distortion disables the focusing, and then, a high quality photograph cannot be obtained. Up to now the drop test has been carried out after fabricating real AF actuator. We propose a dropt test model which simulates the drop test based on finite element analysis. This model makes us enable investigate the stress acting on the clamping and curved parts of leaf spring. Stress over Von Mises criterion lets the spring deformed permanently, and then AF actuator malfunctioned, It helps us to design and modify AF actuator without manufacturing the real product. And also, it saves the time and cost for the development of new products.

Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.

In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

Conventional paternity index and probability of paternity can not be calculated when probe that hybridize to multiple VNTR loci because alleles are not ascertained to specific loci. Therefore, an alternate method based upon the chance of band-sharing used to get paternity index and probability of paternity in this study using multi-locus pV47-2 probe. From 57 parentage cases of Korean pedigree we found 12.08, 11.86, and 12.31 of average DNA fingerprints present in mother, father and child., respectively. Among 614 DNA bands present in 57 children, 7 bands are not assignable to neither number of bands shared between nother and father is 1.71, with mean band-sharing coefficiency of 0.1798. All bands present in the child's pattern but absent in the mother's are 5.14 on average as obligator paternal band, but a child are transmitted 5, 47 from mother. In 10 non-parentage cases, however, a child shared bands of 1.20 on average with a putative father, whereas shared bands of 5.60 with a biological mother. In the paternity test of a child having 3 bands of obligatory paternal origin, paternity index(PI) and probability of paternity(PP) are calculated with the band0sharing coefficiency of 0.18 as 21.4, and 95.4%, respectively. These results suggest that RFLP analysis using multi-locus pV47-2 probe could identify with virtual certainty one particular man as the biological father of a child.

이종석,오혜원 한국화훼연구회 2002 화훼연구 Vol.10 No.2

실내조경시 우리나라 자생식물의 이용현황을 파악하기 위하여 호텔과 백화점, 고급식당, 오피스빌딩, 공항건물, 골프클럽하우스, 대학의 건물, 고속도로의 화장실, 종합병원 등 총 82개소에 식재된 자생식물의 종류와 이용빈도, 식재유형 등을 2001년과 2002년에 걸쳐 조사한 결과는 다음과 같다. 이용된 자생식물의 종류는 상록교목류로서 동백나무, 후피향나무, 굴거리, 호랑가시나무, 후박나무, 측백나무, 향나무, 까마귀쪽나무 등과 상록관목류로서는 팔손이, 백량금, 산호수, 자금우, 식나무, 돈나무 등이었다. 초본류는 문주란, 털머위, 맥문동, 소엽맥문동, 맥문아재비, 석창포, 꿩의 비름, 양치류는 봉의꼬리와 도깨비고비, 만경류는 마삭줄과 송악, 그리고 내나무류로는 조릿대 등 모두 19과 27종이었으며 거의 모두가 상록성 식물이었다. 자생식물의 이용빈도는 자금우가 가장 높았으며 그 다음이 백량금이었고 산호수와 동백나무, 팔손이, 소엽맥문동, 맥문아재비 등이었다. 실내조경공간별로는 오피스빌딩과 공항건물에서 자생식물의 이용도가 높았고 호텔과 백화점에서는 낮았다. 실내조경의 유형은 공항과 오피스빌딩에서는 정원형으로서 적극적으로 도입된 형태이었고 백화점, 병원, 글프클럽하우스, 식당 등은 화분과 걸이형으로서 소극적으로 도입된 형태이었다. The present situation of native plants using for interior landscape in Korea were discussed with special reference to plant species, frequency rate and utilization type. The results were surveyed from 2001 to 2002 at 82 interior landscaping sites divided to 9 landscaping patterns, which are big and higher level of hotel, department store, restaurant, office building, airport building, golf club house, university building, herbaceous perennials, ferns and bamboo, were used for interior landscape plant materials. Evergreen trees were Camellia japonica, Ternstroemia, Daphniphyllum macropodum, Ilex cornuta, Machilus thunbergii, Thuja orientalis, Juniperus chinenesis and Litsea japonica. Evergreen shrubs were Fatsia japonica, Ardisia crenata, Ardisia japonica, Ardisia pusilla, Aucuba japonica, and Pittosporum tobira. Evergreen climbers were Trachelospermum asiaticum var. intermedium and Hedera rhombea. Evergreen perennials were Crinum asiaticum var. japonicum, Farfuguim japonicum, Liriope platyphlla, Ophiopogon jaburan, Ophiopogon japonicus and Acorus gramineus. Ferns were Pteris multifida and Cryptomium fortienei. And bamboo was Sasa borealis. Ardisia japonica, A crenata, and A. pusilla were the most high rate using plant and O. japonicus were observed widely used plants for interior landscpe. In using trend of Korean native plants, high frequency rate was observed in office and airport building; however rare in hotel and department store. Interior landscapes were established positively in airport and office building as garden style, but decorated negatively in depqrtment store, hospital, golf club house and restaurant used as container or hanging plant in general.

Statistical analysis of the 172 congenital heart disease patients who had diagnosed by cardia catheterization and angiography in the Department of Pediatrics, Chungnam National University College of Medicine from Sept. 1982 to Nov. 1985 was performed. The annual numbers of cardiac catheterization is increased. The overall congenital heart disease is most common in less than 3 year age group (27.3%) and then, 4-6 year age group (22.1%), 7-9 year age group (22.1%), 10-12 year age group (17.4%) and 13-15 year age group (11.1%) in this order. The most, common congenital cardiac anomaly is VSD(40.3%), and the next are PDA(28.8%) ASD(11.0%) and TOF(10.7%). VSD is the most common disease in the below 3 year age group, and above 7 year age group and PDA is in the 4-6 year age group.

비장티푸스 살모넬라증에 의한 장열과 장천공은 매우 드물다 저자들은 방어기전의 손상이 없는 건강한 성인에서 비장티푸스성 D군 살모넬라 장열에 동반된 장천공이 발생한 예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. The case of enteric fever and bowel perforation caused by nontyphoidal Salmonella spp. is extremely rare. We report a case of a 28-year-old man who suffered from enteric fever with complicated a small bowel perforation, which is a known complication of S. typhi and S. paratyphi infections. The culprit later proved to be nontyphoidal group D Salmonella spp. in our case.
