  • This study was conducted to evaluated the effects of different sowing time(October 22, February 20, March 3, March 13, and March 23) and sowing quantities(150kg/ha, 200kg/ha, 250kg/ha, and 300kg/ha) on growth of naked oat(Avena sativa L.) cultivar(Choyang-Gwiri) at a cultivation area in Iksan, south Korea. Heading times were delayed with later sowing times. In autumn seeding(Oct. 22) the ear was headed at April 30, in spring seeding(Feb. 20, Mar. 3, Mar. 13, and Mar. 23) heading times were respectively May 14, May 14, May 15, and May 19. Heading time of spring seeding was delayed about 3 weeks than autumn seeding. Ripening times were similar trends to the heading times. In autumn seeding ears were ripened at June 7, in spring seeding each times were respectively Jun. 15, Jun. 13, Jun. 20, and Jun. 20. Ripening time of spring seeding was delayed about 2 weeks than autumn seeding. Culm length and ear length were shortened in spring seeding, but number of plants per $m^2$ were increased. Number of grains per a ear were 106 in autumn seeding, but grains per a ear in spring seeding were respectively 88, 83, 83, and 73. Weight of 1,000 grains in spring seeding was heavier than that in autumn seeding, the weights were tend to light as later seeding times. Yield of grains was declined as later seeding times, yield of in autumn seeding was 2,900kg/ha, whereas that in spring seeding was 2,180kg/ha. The highest yield of spring seeding time was in Mar. 13, before this seeding time soil surfaces were severely dried as few rain fall, so germination was poor in those seeding times. As several seeding quantities were seeding, earing and ripening times were not different. but increasing seeding quantity, culm length was lengthened and ear length was shortened, number of plants per $m^2$ were increased and grains per a ear were reduced. Yield of grains were increased more seeding quantities, yield was highest up to 250kg/ha seeding quantity.

  • This study investigated the anti-inflammatory effects of Xanthoceras sorbifolia of seeds oil on RAW264.7 macrophages and TPA (12-O-tetra decanoylphorbol-acetate)-induced ear edema mice. MTT assay method to measure cytotoxicity was formed in RAW264.7 cell. The anti-inflammatory effect was measured by ability to inhibit production nitric oxide (NO) in RAW264.7 cell. Hexane and eight-percent methanol fractions from Xanthoceras sorbifolia seeds oil did not show cytotoxicity. Hexane and eight-percent methanol fractions were showed significantly inhibitory effect on NO production. TPA-induced acute edema was developed in the mouse ears, and Xanthoceras sorbifolia seeds oil dissolved in acetone was applied to inflamed ears. It was found out that Xanthoceras sorbifolia seeds oil could significantly reduce th ear swelling, compared to the control. Overall results indicate that the Xanthoceras sorbifolia seeds oil has anti-inflammatory activity and could be used as a resource of anti-inflammatory materials.

  • 한국해양연구소는 1998년에 이어도 종합해양과학기지의 기본설계를 수행한 바 있으며 심해 설계파에 Morison 식과 Stream function 이론을 적용하여 설계파력을 결정한 바 있다. 본 연구에서는 삼차원 수리모형실험 통하여 이어도 해역에서의 파랑전파를 모의하였으며, 구조물의 파력 및 Air gap를 계측하고 이들을 SACS 프로그램의 계산치와 비교함으로써 기본설계 값들의 타당성을 검토하였다. 그 결과, 시도된 4개의 심해파향 중에서 SSW, S, SE계열의 파향에 대해서는 계측치가 SACS 계산치 보다 작게 나타났다. 그러나, 유일하게 구조물에 미치기 전에 쇄파되는 NNW계열의 파향에서는 전반적으로 SACS 계산치를 상회하였으며, 그방향성 흐름과 파가 복합되어 있는 경우와 매우 유사한 파력변화를 보여주었다. 구조물의 Air gap은 모든 심해파향에 대하여 계측치가 기본설계치보다 작은 것으로 나타났다.

  • Unlike human, with some exceptions, animals do not heal with excessive scar. The lack of suitable animal model has hindered the development of effective scar therapy. We previously reported that partial thickness rabbit ear wound model resembles human wound heal process. This study was designed to prepare a hypertropic scar wound model which can be employed for testing anti-scar therapy. Four wounds were created down to the bare cartilage on the anterior side of each rabbit ear using 8-mm dermal biopsy punch and histology analysis at post operation day (POD) 5, 28 and 48 were performed. As the outcome of scar formation is largely determined by the early inflammatory response to the wounding and the degree and the duration of occlusion, cephalodin(50 mg/kg) was injected daily and medical occlusive dressings were applied. Five micro wound and scar sections were stained with hematoxylin and eosin for quantification of epidermal regeneration and scar hypertrophy. Sections were also stained using Masson's trichrome and Sirius red to evaluate collagen organization and rete ridge formation. Wound closure process was assessed to 7wks post wounding. Complete removal of the epidermis, dermis and perichondrial layer caused delayed epithelialization, which results in hypertropic scarring. The inability of the wounds to contract and the delay in epithelialization in rabbit ear was likely due to cartilage and it created scar elevation. The results suggest that full thickness surgical punch wound model in rabbit ear could be employed as a reliable and reproducible scar wound model for testing anti-scar therapy.

  • The importance of fast and accurate body temperature measurement with a portable thermometer is increasing. In order to reduce the temperature measurement response time of the infrared ear thermometer, it is very important to develop a structure for a thermometer having an efficient heat transfer path. Most of the existing ear thermometers are single structures that do not consider thermal efficiency, which may delay measurement time and reduce measurement accuracy. Therefore, in this study, the upper part of the thermometer in contact with the ear is made of a thermally conductive material, and the lower part of the thermometer is made of a thermal barrier material so that heat can be concentrated on the infrared sensor of the thermometer by blocking the upper part of the heat. For the efficiency of production, it was intended to be manufactured through the double injection process, and for this purpose, in this paper, the optimal process parameters were derived through the double injection process analysis.

  • A 12-year-old castrated male Shih Tzu presented with suspected hearing loss. The patient had no history of head trauma or exposure to ototoxic drugs. The results of neurologic and physical examinations were normal. An otoscopic examination showed that both the tympanic membranes and the external ear canals had a normal appearance. However, the results of brainstem auditory evoked response tests confirmed sensorineural deafness in the right ear and indicated conduction disturbances and brainstem abnormalities in the left ear. Magnetic resonance imaging was performed to confirm the causes of the conduction disturbances and brainstem abnormalities. Inflammatory changes in the left middle ear were highly suspected to be responsible for the findings in the left ear. The results of these examinations confirmed complete hearing loss in the right ear and indicated otitis media in the left ear, which could have been the cause of the conduction disturbances.

  • 폐질환은 대부분 흡연과 대기 오염으로 발병하며 한 번 손상된 폐는 기능 회복이 어려워 생명 연장의 위험 질환이며 현대인의 6대 질병 중 하나로 사회적 관심이 증대되고 있다. 따라서 평소 흡연을 하지 말며 폐 기능 강화를 위한 행위를 행해야 호흡기 질환으로 고통 받는 경우의 수를 줄일 수 있을 것으로 여겨진다. 본 논문에서는 귀의 혈 자리가 인체 장기와 연계되어 있다는 이혈요법을 적용하여 폐와 상응하는 귀의 혈 자리를 자극했을 때 실제 폐 기능 강화에 도움이 되는지를 음성 분석 기술에 의해 규명하는 방법을 제안하고자 한다. 이를 위해 우선 인체가 폐에 미치는 영향을 분석하기 위한 선행 연구로 흡연 전/후의 음성 변화를 고찰하고자 한다. 이를 기반으로 폐와 상응하는 이혈점을 자극하기 전과 후의 음성 특징 차이를 분석하여 폐의 이혈점 자극이 실제 폐 기능 향상에 도움이 되는지를 수치적, 정량적으로 규명해 내고자 한다.
