총의치 환자에 있어 Permanent record base를 이용한 악간관계 기록

허윤석,신상완 大韓齒科補綴學會 1995 대한치과보철학회지 Vol.33 No.2

When the complete denture is made, the record base for jaw relation is divided into temporary record base and permanent record base. However, The temporary record base include some disadvantages such as, the lackness of intimate contact between model and base, the lackness of retention during the jaw relation registration, When we obtained jaw relation the permanent record bases made from heat curing resin were utilized. We could get several advantages as follows : 1. The permanent record base provided intimate contact between the model and record base. 2. In fabricating occlusal rim on record base, the dimensional change of record base was little because the permanent record base was lesser influenced to thermal change of occlusal rim than the temporary record base. 3. At the stage of jaw relation, the retention of final denture could be early checked. 4. It could be able to get more accurate registration of jaw relation because all procedure were done on the same base during the jaw relation, artificial teeth arrangement, try-in, and final denture construction. 5. Although there was an inconvenience due to double curing procedure, the shrinkage rate in resin polimerization was relatively reduced so that more dimensional stability could be taken

광역시 소재 꽃집 10곳과 서울 소재 꽃전문 온라인 쇼핑몰 3곳의 매출실태를 조사하였다. 꽃집의 매출액은 절화상품(65.0%), 관엽식물(19.3%), 난(14.8%), 기타(0.9%)순으로 많았으며, 품목별로는 경조화환(32.5%), 꽃바구니(23.4%), 관엽식물(19.3%), 난(14.8) 순으로 많았다. 온라인 쇼핑몰의 매출액은 절화상품(87.6%), 난(5.8%), 관엽식물(3.4%), 기타(3.2%)순이었으며, 품목별로는 꽃바구니(37.0%), 박스플라워(23.5%), 꽃다발(20.1%), 난(5.8%) 순으로 많았다. 판매건수는 꽃집의 경우 꽃바구니(28.1%), 꽃다발(20.8%), 관엽식물(15.0%)의 비율이 높았으며, 꽃 전문 온라인쇼핑몰은 꽃바구니(34.44%), 박스플라워(27.2%), 꽃다발(23.2%)의 비율이 높았다. 판매단가는 품목에 관계없이 꽃 전문 온라인 쇼핑몰이 꽃집 보다 비싸게 조사되었다. 꽃집에서 꽃 판매 형태는 가정용 절화는 100% 꽃다발은 77%가 직접 방문에 의해 판매되었고, 꽃바구니, 꽃다발, 박스플라워는 80%이상이 전화주문에 의해 구매된 것으로 나타났다. This survey was conducted to investigate the actual condition of flower sale in shopping mall for flower and flower shop, which is located in some metropoltan cities. In the case of flower shop. rate of selling amount is 65% for cut flower, 19.3% for foliage plant, 14.8% for orchid and 0.9% for others. Among the cut flowers, wreath for celebration or condolence account for 32.5%, flower basket 23.4%. foliage plant 19.3% and orchid 14.8%. In the case of online shopping mall, rate of selling amount is 87.6% for cut flower, 5.8% for orchid and 3.4% foliage plant. Number of sale, in flower shop, was very high orderly at flower basket(28.1%), bouquet(20.8%) and foliage plant(15%). However, shopping mall showed that number of sale was high at flower basket(34.4%), box flower(27.2%) orderly. Sale price was higher in online shopping mall than in flower shop independent on items. Form of flower sale, in flower shop, was appeared that 100% for home and 77% for bouquet were soled by visiting, above 80% of flower basket, bouquet and box flower were soled by telephone.

소양호 유역에서 비점오염원의 홍수유출과 오염수괴의 호수내 이동

허우명,김범철,김윤희,최광순 江原大學校 附設 環境硏究所 1998 環境硏究 Vol.15 No.-

In Korea most of nutrient tending into lakes is concentrated in stormy seasons. Phosphorus lording and transport of turbid storm runoff water was investigated in a reservoir, Lake Soyang, Korea. Concentration of phosphorus was measured at ten meter intervals on the monthly babe in dry seasons and biweekly in stormy seasons. The loading from drainage basin was determined by measuring total phosphorus (TP)concentration in the main in flowing stream, the Soyang River. Because total phosphorus concentration and flow rate of the Soyang River was high in flood period, most of annual phosphorus tending was concentrated in several sporadic storm runoff. In July of 181)8 phosphorus input was 418 tP/month. It was much higher than that in June, 6.0 tP/month. 10% of annual total phosphorus input was discharged through outlet during the period from ,lune to October. Turbidity was much higher(2~ 78 NTU) in stormy seasons than in dry seasons (1 ~ 9 NTU). Cold storm runoff laden with high turbidity and phosphorus flowed into metalimnion along the layer of same densify. Total phosphours concentration of intermediate turbid water ranged from 20 to 230 ?gp/m³. After stormy seasons high nutrient concentration was con-sistently observed at intermediate layer until autumn turnover. In autumn descending mixing depth caused increase of phosphorus concentration in the epilimnion.

허북구,박윤점,이일병,윤재길 한국화훼연구회 2002 화훼연구 Vol.10 No.2

원예치료용으로도 다수 이용되고 있는 허브식물의 특성 파악과 정확한 구분, 교육 및 연구에 효율적으로 이용할 수 있는 기초자료 수립측면에서 허브식물 97종의 속명 어원을 조사하였다. 허브식물의 속명 유래를 조사한 결과 성분 및 용도(27.8%), 언어명(23.7%), 형태(13.4%), 신화(7.2%), 향기(6.2%), 생육습성(6.2%), 색깔(5.2%), 인명(4.1%), 기타(00%)에서 유래된 것 순이었다. 성분 및 용도에서 유래된 것은 주로 약리 작용에서 유래된 비율이 높았다. 언어명에서 유래된 것은 주로 고대 그리스 및 로마시대의 식물명이었다. 형태에서 유래된 것은 허브식물의 잎과 줄기, 꽃 및 뿌리가 속명의 유래원이었다. 신화에서 유래된 것은 주로 기쁨이나 약효와 관련된 것이었다. 향기에서 유래된 것은 식물의 전체 혹은 종자에서 냄새가 나는 것에서 유래되었다. 생육습성은 자생지역이나 개화습성, 덩굴성 등의 특성이 반영되어 있었다. 기타 식물의 꽃, 잎, 뿌리의 색깔과 왕의 이름, 맛 지명, 벌, 꽃이 아름다운데서 유래된 것이 있었다. The derivation of genera names in 97 herb plants were investigated to obtain the basis information useful for understanding the characteristics of herbs, classifying correctly, teaching and researching about them. Most genera names were derived from constituent and utilization(27.8%), and followed by language(23.7%), morphological characters(13.4%), myth(7.2%), odor(6.2%), color(5.2%) and human's name(4.1%) orderly. Genera names derived from constituent and utilization were originated mostly from medicinal effect, and those from language name were mostly originated from the plant names of Greek and Rome. Genera names derived from myth were mostly originated from delight and medicinal effect, and those from oder were originated from order of whole plant or seed. Genera names derived from growth habit indicate the character of flowering habit, native location and vine. The others of genera names were originated from the color of flower, leaf and root, king's name, taste, place name and flower beauty.

WLL 기지국용 다운 컨버터 설계

김윤영,문성익,허광삼,양두영 제주대학교 산업기술연구소 2000 尖端技術硏究所論文集 Vol.11 No.1

In this paper, A down converter to convert RF signal into IF signal is designed at the WLL base-station. It consists of low noise amplifier module and down mixer module. The low noise amplifier module is composed of three-stage and a feedback circuit is added in the first-stage low noise amplifier in order to obtain unconditional stability and good flatness. The configuration of the down mixer module is a single-ended type gate mixer. For the good isolation characteristic of each port, a bandpass filter and a lowpass filter are inserted in the input and output port. To design the down converter without the IF power amplifier, it is important to maximize conversion gain. So the down converter of this paper is designed for the purpose of obtaining a high conversion gain. From the results, the IF output power is -12.68dBm when the LO and the RF power level are 7dBm and -80dBm, respectively. Also when the LO power level is 7dBm, P1dB is -0.19dBm, and the RF input power range shows 70dB on wide operating range.

박윤점,허북구,서춘순,송채은,정주연 韓國植物ㆍ人間ㆍ環境學會 1999 인간식물환경학회지 Vol.2 No.1

This survey was carried out to investigate kinds and origins of flower languages of common flowering plants and standardize them. A flowering plant has about 5 kinds of flower languages. Differnt literatures have different flower languages for the same flowering plant. So differnt flower languages need to have standard flower languages. Flower languages originate from shape(8.0%) > color(7.5%) > characteristics(4.4%) > mythology and legend(4.9%) > scientific name(2.3%) > flowering time(1.8%) > perfume(0.9%) > and others(1.7%). The origin of 68.5% of flower languages was found to be obscure.

The purpose of this study was to investigate the effect of mental practice on shooting performance. The subjects were 20 male students who were belonging to the department of Physical Education in I city. They were randomly devided into two groups (control and experimental group). The subjects in experimental group were trained by Skinks rifle video tape for 8 weeks and the subjects in control group were not trained for 8 weeks. Before and after 8 weeks training, All subjects performed 10 M rifle shooting and the records were analyzed by t-test. The results were summarized as follows; 1. After 8 weeks training, the performance of control group in shooting was increased but it was not shown a significant level. 2. After 8 weeks training, the performance of experimental group in shooting was significantly increased.(p< .001) 3. After 8 weeks training, the performance of experimental group in shooting was significantly higher than that of control group. (p< .01)
