Coronary artery anomalies are found incidentally in approximately 1% of all patients undergoing routine coronary angiography. Of these, an isolated single coronary artery anomaly is the rarest one. Patients with an isolated single coronary anomaly may present with symptoms such as angina pectoris, myocardial infarction, arrhythmias, syncope, sudden death, and congestive heart failure. We report a case of single coronary artery anomaly with the left anterior descending and left circumflex coronary artery originating from the right coronary artery.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

The purpose of this study is to suggest the digitalizing model of visual relationship information. For this study, the psychological demands of people are analysed based on the premise that the formation of various space is made by mental needs rather than functional needs. The Digitalized visual model consisted of such structuring factors, the positions of visual points and objects, the distance between visual points and objects, and the visual quantities between visual points and objects are proposed. As a result, the suggested digitalizing model will be considered as an efficient tool for the objective analysis of visual relationship between space. In addition, the model will contribute to the expansion of terminology in the field of digital space design.

최근에 개발된 나노 충전제를 microhybrid 복합레진에 첨가할 때, 나노 충전제 함량이 중합에 미치는 영향을 조사하기 위해, 실험적으로 나노 충전제의 함량을 다르게 제작한 복합레진에서 광중합 후 미세경도를 측정, 분석하여 다음과 같은 결론을 얻었다. 1. 나노 충전제의 함량이 2%, 3%인 군은 0%, 1%인 군에 비해 중합된 면의 미세경도가 유의하게 높았으나(p<0.01), 그 차이는 크지 않았다. 2. 나노 충전제의 함량이 높을수록 레진 시편의 하면에서의 미세경도는 증가하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). 3. 레진 시편의 상면과 하면의 미세 경도 차이는 나노 충전제 함량이 높을수록 감소하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). The objective of this study was to evaluate the effects of nanofiller content on the microhardness and polymerization of experimental microhybrid composites. The nanofiller contents in the experimental composites were varied (0%, 1%, 2%, 3%), while the total filler content remained constant as 76 %wt. We obtained the following results: 1. The microhardness of the top surface for the 2%, 3% nanofilled microhybrid composites were significantly higher than those for the 0%, 1% nanofilled composites (p<0.05), but the difference was not great. 2. The microhardness of the bottom surfaces significantly increased with an increase in the nanofiller level (p<0.05), except between the 2% and 3% nanofilled groups (p>0.05). 3. As the nanofiller level increased, the difference beween microhardness of top and bottom surfaces significantly decreased (p<0.05), except between 2% and 3% nanofilled groups (p>0.05).

Our communities have been exposed to polluted air. Polluted air could cause the serious injury such as respirational impediment, disease and so on, and the air pollution could be most serious problem in our life. Unfortunately, we didn't have consider these problems seriously, and we had make no solutions for these problems. Although the concentration of indoor and outdoor didn't show the high values, VOCs existed in indoor and outdoor environment. The indoor concentration was more higher concentration than the outdoor concentration, that indicated the indoor environment was more polluted. This study showed that the investigation of a continuous environment polluted were needed.

These studies were conducted to control of apple cankers caused by Valsa ceratosperma strains by treatment of chemical compounds, antibiotics, extracts of herbal plants and compounds produced from mutant of Streptomyces melanosporofaciens. Effects of chemical control for apple canker were evaluated by grwoth inhibition of Valsa ceratosperma on the PDA media and the most effective chemical was found to be berberine followed by neoasogin, branchi Q, in general. Inhibitory concentration of Valsa ceratosperma was 500mg/ℓ in berberine, and l0,000mg/ℓ in neoasogin. The antifungal antibiotic, cycloheximide, was effective for growth inhibition of Valsa ceratosperma; all strains were inhibited on the media with l00㎍/㎖ of cycloheximide and M26 strain was inhibited by lower concentration of 10㎍/㎖. Effects of extract of herbal plants for growth inhibition of Valsa ceratosperma were excellent with Phellodendron amurense and Coptis japonica, and especially in Coptis japonica, low concentration of l,000mg/ℓ was effective. Compounds produced from mutant of S. melanosporofaciens for growth inhibition of Valsa ceratosperma were more effective than other compounds, i.e., chemical compounds, antibiotics and extracts of herbal plants. Minimum inhibitory concentration of compound C-1 for IF03025 and M1099 was 31.25㎍/㎖.

A series of experiment was carried out to contribute in establishing a model of pruning through investigating in relation to the tree form, tree vigour, yield and fruit quality in 4-examplary orchards practising unique pruning methods. The major results can be summarized as follows. 1. Sizes for height of trees were in the order of steady, thinning-out only("T" pruning)<steady, short, heading-back only("H" pruning)< steady, long heading-back with thinning-out only("H+T" pruning)=three years short heading-back only then thinning-out only("3HT" pruning). 2. The number of flower buds per 10a of branch was in the of three years short, heading-back only then thinning-out only> steady, thinning-out only> steady, short, heading-back only> steady, long heading-back with thinning-out only. Also, the size of flower bud for 6-year old 'Fuji' apple tree was in the order of steady, thinning-out only> three years short, heading-back only then thinning-out then thinning-out only> steady, short, heading-back only = steady, long heading-back with thinning-out only. 3. The carbohydrate/nitrogen(C/N) ratio in bark of one-year-old shoot was high in steady, thinning-out only and was low on the other three pruning treatments. 4. In accumulated yield for 8 years of cropping, the fruit number per 10a was in the order of steady, thinning-out only=steady, short, heading-back only>three years' short, heading-back only then thinning-out only. Also the yield per 10a was in the order of steady, thinning-out only > steady, short, heading-back > steady, long heading-back with thinning-out only = three years' short, heading-back 5. The percentage of incident light intensity, relative to the outer canopy, into the innermost part of the canopy belonging 1.0m-1.5m abvoe the ground and within the radius of 0.5m around the main stem, was in the order of steady, thinning-out only > three years' short, heading-back only then thinning-out only > steady, short, heading-back only = steady, long heading-back with thinning-out only. 6. The distribution percentages of fruits coloured with 60% and over were in the order of steady, thinning-out only > three years' short, heading-back only then thinning-out then only = steady, long heading-back with thinning-out only > steady, short, heading-back only. While the distribution percentages of fruits weighting over 300g each were in the order of steady, long heading-back with thinning-out only = steady, thinning-out only;> three years' short, heading-back only then thinning-out only = steady, long heading-back with thinning-out only. 7. The content of chlorophyll b in fruit skin from steady, thinning-out only pruning treatment was less while the content of anthocyanin in fruit skin from steady, thinning-out only pruning treatment was compared with the other three pruning teatment, respectively. 8. The soluble solid contents of fruits were in the order of steady, thinning-out only > three years' short, heading-back only then thinning-out only> steady, long heading-back with thinning-out only. While the titratable acidity content was higher in steady, thinning-out pruning then the other three pruning treatments.
