The button mushroom (Agaricus bisporus) is one of the most widely cultivated important edible mushroom species. In the breeding of new button mushroom, ‘Seolgang’ was developed by crossing two monokaryons ‘CM020913-27’ and ‘SSU423-31’. Because of the secondarily homothallism, only a small percentage of the basidia produce 3 or 4 spores, which are mostly haploid (n) and do not fruit. Single spore cultures derived from these types of spores produce a vegetative mycelium that also contain a variable number of genetically identical nuclei per cell called monokaryon. The lack of clamp connections between monokaryon and dikaryon required a series of mycelial culture and fruiting test. After crossing, hybrids were cultivated on a small scale and on a commercial scale at a farm. For this, the spawn was made by a commercial spawn producer and the spawned compost by a commercial compost producer. Mycelial growth of ‘Seolgang’ on CDA was better at 20℃ and 25℃ when it was compared with that of ‘505 Ho’. The mature cap shape of new strain ‘Seolgang’ is oblate spheroid and the immature cap shape is round to oblate spheroid. The cap diameter was 41.2 mm on average. In comparison with white strain ‘505 Ho’, the strain had a yield that was 9% higher. It produced fruiting bodies which had a higher weight on average per fruiting body and were 19% firmer with a good shelf life. Days of fruiting body were 3-4 days later than those of ‘505 Ho’. The physical characteristics such as elasticity, chewiness, adhesiveness were better than that of ‘505 Ho’. Genetic analysis of the new strain ‘Seolgang’ showed different profiles compared to ‘505 Ho’, CM02913-27, SSU413-31, when RAPD primers A02 and O04 were used.

역위 매복된 상악 중절치의 외과적 재위치 후 치근 발육 정지

송제선,최병재,최형준,김성오,손흥규,이제호 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.1

상악 중절치의 매복은 소아 환자의 심미적 사회적 기능적 문제를 일으킬 수 있어 적절한 치료를 통해 바로잡아 주어야 한다. 상악 중절치 매복의 치료로 외과적 노출 후 교정적 견인이 어려울 경우 발치하기에 앞서 외과적 재위치(surgical repositioning) 혹은 치조 내 자가치아이식(intra-alveolar autotransplantation)을 고려해 볼 수 있다. 본 증례는 5세 9개월 된 남아의 역위 매복된 상악 우측 중절치를 치근 발육 초기인 Nolla's stage 6.5에 부분 맹출된 위치로 외과적 재위치를 시행하여 자발적 맹출을 기대하였으나 21개월 간의 추적 검사 결과 치관 발육 및 맹출이 정지된 증례이다. 그 원인으로서 수술 시 치배를 발거하고 치조와를 적합하는 과정에서 Hertwig's epithelial root sheath(HERS)가 손상 받았기 때문으로 생각된다. 매복 치아의 외과적 재위치 시에는 본 증례와 같이 합병증 발생 가능성이 있으므로 신중한 적응증의 선택, 치근 발달 정도를 고려한 적절한 치료 시기의 결정, 최소한의 손상을 주는 외과적 술식 등의 노력이 필요할 것이다. Impaction of the maxillary central incisor may cause social, esthetic, and functional problems in children. There are various means of treatment for the inverted maxillary central incisor, such as extraction, surgical opening followed by orthodontic traction, surgical repositioning or intra-alveolar autotransplantation prior to extraction. In this case, we surgically repositioned the inverted maxillary central incisor to normal semi-erupted position in a 5-year-old boy. The developmental stage of the inverted tooth was Nolla’ s 6.5, which indicates formation of less than one third of the root. After surgical reposition, we did follow-up for 21 months, expecting spontaneous growth. Unfortunately, poor prognosis was noted : further root was not observed. Such failure seems to originate from possible injury on Hertwig’ s epithelial root sheath by surgical trauma. We performed surgical repositioning to retain the tooth instead of extraction. However, arrest of root development occurred, which is one of the critical complications. In order to increase the success rate of the surgical reposition procedure, minimal surgical trauma is required as well as selection of adequate indication and decision of proper time of treatment considering the stage of root development.

송병섭,노철균,김명남,조진호 한국센서학회 2002 센서학회지 Vol.11 No.3

이식형 인공중이에 사용되는 일반적인 전자기 방식의 진동 트랜스듀서에 비하여 두 개의 소형 영구자석을 같은 극끼리 접착한 후 코일내부에 위치시킨 차동 전자 트랜스듀서는 효율이 높고 코일-영구자석간의 공극조정이 필요 없으며 외부의 자기장에 대하여 영향을 받지 않는 특성을 가진다. 본 논문에서는 이러한 차동 전자 트랜스듀서를 이식형 인공중이 시스템에 사용하기 위하여 입력전류에 대하여 진동력의 크기를 최대화시킬 수 있는 효율적인 구조를 제안 해석하였다. 유한요소 해석을 통하여 가장 효율적인 코일과 자석의 길이 비를 도출하였고 소리신호 전달을 위한 트랜스듀서의 필요 진동력을 산출한 후 트랜스듀서 발생 진동력을 해석하였다. 그리고 실제 이소골에 이식할 수 있는 크기의 트랜스듀서를 제작하기 위한 설계상수를 추출하였다. 계산된 설계상수를 이용하여 이식 가능한 크기로 트랜스듀서를 구현한 후 무부하 실험과 사체 부하 실험을 실시하여 제작된 트랜스듀서가 실제 중등이상 고도난청자를 위한 이식형 인공중이 시스템에 사용될 수 있음을 증명하였다. The differential electromagnetic transducer for IME(implantable middle ear) system, which have two small permanent magnets glued with the same pole facing each other in the coil, has high vibration efficiency and does not influenced by external magnetic field. In this paper, using finite element method, highly efficient structure of the transducer was proposed and vibration force of the transducer was calculated by electromagnetic theory. And the necessary vibration force of transducer to transmit the sound signal to inner ear when the transducer is attached at stapes was calculated and the design parameters of the transducer were investigated. Using the parameters, the differential electromagnetic transducer was manufactured in small size to implant in confined human middle ear. And it was examined by unloaded and loaded vibration experiment using temporal bone sampled from cadaver.

송병철,김범준,정주영,염충호,이대호,김진석 제주대학교 생명과학연구소 2003 제주생명과학연구 Vol.6 No.1

Background/Aims: The genotype of HBV has been suggested to correlate with the clinical outcome of HBV infection. We analyzed the distribution of HBV genotype according to the clinical outcome of HBV infection in Jeju island. Methods: A total of 145 HBsAg-positive samples were enrolled. To identify specific patterns of HBV genotypes, we performed restriction fragment length polymorphism (RFLP). If typical restriction pattern of RFLP was not determined, phylogenetic analysis was performed. Results: RFLP analysis was possible in 65 patients. Clinical diagnoses of the 65 patients with chronic liver disease were as follows: HBeAg-positive healthy carrier (HBeAg+, anti-HBe-, HBV DNA+, transaminase normal: n=20): HBeAg seroconversion (n=12): chronic hepatitis B (n=14): liver cirrhosis (n=9): hepatocellular carcinoma (n = I0). Sixty-two patients showed typical restriction pattern by HinfI. However, 3 patients showed unique restriction pattern by HinfI, which were not reported in literature. When phylogenetic analysis was performed to classify the genotype of these 3 patients, they were also genotype C. Whereas, all patients showed typical restriction patterns by Tsp509l, which were reported in genotype C. Conclusion: All chronic HBV infection are genotype C in Jeju island regardless of clinical outcome.

宋又準,金丙鎬 진주농과대학 1968 진주농과대학 연구논문집 Vol.- No.7

산딸기 主産地 住民들이 蜜蜂의 有害說을 主張하여 蜜蜂의 轉飼를 배척하고 蜜蜂의 訪花는 싸락딸기가 되게 한다는 여러 가지 有害說을 해소시켜 주기 爲하여 산딸기에 蜜蜂의 花粉媒介 效果試驗을 實施하였던바 다음과 같은 結果를 얻었다. 1) 산딸기는 蜜蜂의 訪花가 없으면 0.059%의 結實에 不可하였고 無蜂區 100으로한 指數比는 有蜂區가 1963으로 산딸기 結實에 蜜蜂의 訪花는 必要한 要因이며, 多收?에 큰 功獻을 한다. 2) 果實重量은 有蜂區는 最少 1g에서 最大 3g으로 平均 1.76 ±0.081g 無蜂區는 最少 0.03g에서 最大 0.1g으로 平均 0.05 ±0.003g로서 현저한 差異가 있었으며, 이로서 蜜蜂의 訪花는 果實의 正當化와 重量을 增加하고 品質을 良好케하여 주어 單位面積當 增收를 圖媒하고 있다. 3) 1果當 果粒數는 有蜂區가 最少 37에서 最多 126 平均 71.61 ±3.63個 無蜂區는 最少 1에서 最多 5個 平均 2.29 ±0.19個로서 蜜蜂의 訪花가 없으며, 싸락딸기가 全部되고 따라서 商品價値가 전혀없어 졌으며, 生産의 經濟性을 完全히 상실하였다. 4) 산딸기는 蜜蜂이나 基他 有用昆蟲에 依한 他花授精을 위주로 結實되는 蜜源植物로 考察되어졌다. 5) 産蜜成績이 優秀하여 蜜源價値가 優秀하고 또 산딸기는 蜜源植物로서 보급의 장래성이 기대된다. The dwellers cultivating wild berry in its chief producing districts keep bee-keepers from moving their beehives to the districts because they belive that the wild berry visited by honey-bee becomes the Salak wild berry. Therefore this experiment was conducted to remove the misunderstanding that honey-bee is harmful to the wild berry. The experimental results obtained were as follows; 1. When wild berry was not visited by honey-bee, it bore only 0.059% fruit. Comparing rate of an exponent the wild berry visited by honey-bee was 1693 against the wild berry not visited by honey-bee 100. The wild berry had good yield because it was visited by honey-bee. 2. In weight of wild berry fruit the wild berry visited by honey-bee averaged 1.76 ±0.081g from the minimum 1 g to the Maximum 3 g and the wild berry not visited by honey-bee averaged 0.05 ±0.003 g from the minimum 0.03 g to the maximum 0.1 g. Therefore wild berry-viewing of honey-bee was the cause of the wild berry normalcy, gained weight and good quality. 3. In numbers of granules the wild berry visited by honey-bee averaged 71.61 ±3.63 from the minimum 37 to the maximum 126 and the wild berry not visited by honey-bee avereged 2.29 ±0.19 from the minimum 1 to the maximum 5. Therefore as the wild berry was not visited by honey-bee, it all became Salak wild berry and lost the economic value of its production. 4. It was considered that the wild berry was the honey plant chiefly cross-fertilized by the honey-bee and other insects. 5. As the wild berry yielded much honey and was an important honey plant, it was expected to become popular as an economic honey plant.

송병호 국립특수교육원 2003 특수교육연구 Vol.10 No.1

이 연구의 목적은 탄성밴드를 이용한 체간 등속성 근력강화 운동이 뇌성마비 아동들의 앉는 자세에 미치는 효과를 알아보려는 것이다. 이를 위해 16명(남자 7명, 여자 9명) 나이 5세에서 16세의 뇌성마비 아동들을 대상으로 12주 동안 주 5회 매회 1시간 운동치료를 실시하였다. 탄성밴드를 이용하여 체간 근력 강화를 위해 등속성 운동을 실행한 후 뇌성마비 아동들의 앉은 자세의 기울기를 앞뒤로 그리고 좌우로 측정하여 비교했다. t-검정 결과를 요약하면 다음과 같다. 첫째, 적용 후 앉은 자세에서 앞뒤로의 평균 기울기(anterior-posterior sitting postural sway)가 적용 전 평균 기울기보다 발전하였으며, 그 차이는 통계적으로 유의한 것으로 나타났다. 둘째, 적용 후 앉은 자세에서 좌우로의 평균 기울기(medial-lateral sitting postural sway )가 적용 전 평균 기울기보다 발전하였으며, 그 차이는 통계적으로 유의한 것으로 나타났다. 이러한 결과로 미루어 탄성 밴드를 이용한 체간 근력 강화 운동 치료에 참여한 뇌성마비 아동들의 앉은 자세가 치료 후 평균 기울기가 치료 전의 평균 기울기보다 발전하였음을 보여줘 탄성 밴드 체간 근력 강화 운동이 앉는 자세의 변화에 효과가 있음을 알 수 있다. Cerebral palsy children show abnormal performance on standard tests of static sitting balance. This study investigated the effect of an exercise using elastic Thera-Band strengthening trunk muscles on the sitting posture of children with CP. 16 cerebral palsy children(male: 7, female: 9) age between 5 year-old to 16 year-old were received the one hour treatment 5 times a week for 12 weeks. The measurements had been taken before the treatment started and after the treatment completed. The results were as follows; 1.There was the significant difference in anterior-posterior sitting postural sway after the 12 weeks' treatments had been completed. 2.There was the significant difference in medial-lateral sitting postural sway after the 12 weeks' treatments had been completed. Therefore, from this results the elastic band exercises are effective to help to correct and prevent the static sitting postural sway for the children with cerebral palsy.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

Catalystic steam gasification of char has been carried out in a thermobalance with a mixture of potassium sulfate and nickel nitrate as catalyst. The catalytic activity of the salt mixture is found to be fairly good, but does not reach the activity of potassium carbonate. Steam gasification of coal has been performed in a 0.15 m i.d. × 2.0 m height internally circulating fluidized bed with coal feed rate of 2.3 ㎏/h. The composition of product gases from both the annulus and draft tube region have been measured. At reaction temperature of 800℃, the calorific value of gas evolved from the annulus is found to be relatively high as 7.5MJ/㎥. Some modification of the reactor configuration will help to reduce the entrainment of fine particles.

Lifht is an important consideration in environmental design. It constantly changes, and changes in light indicate, among others, the presence or absence of shadow, changes in depth, and a number of cues that subconsciously affect how built-environment user moves through and uses space. Color is another vital factor. The interaction of light and color can provide information on depth, distance, emotional tone of the space, practical use of the space, and even the appropriate rate of movement. Simply put, these two elements provide an abundance of information, including the critical, to the environment user. This study examines these elements in planning mainly the interior space for the elderly whose problems include a reduction in the ability to differentiate color, as well as a diminished ability to perceive contrast and to interpret depth cues.
