  • This study reveals the absence of standard design guidelines by region through investigation and analysis centered on public design cases by region in Jeollabuk-do and design elements that can reflect the integration, identity, and diversity of public design in each region by five regions. Through this, the following conclusions could be obtained. First, to improve the quality of street facilities in Jeollabuk-do, the design elements (design motif, color, pattern) applicable to the standard design were analyzed by dividing them into five regions. As a design motif, it was possible to extract patterns containing straight lines, sophistication, dignity, and smartness. In the Northeast region, it is comfortable with the motif of the mountain ridge reflecting geographical characteristics, and it can be extracted elements that contain warm and natural colors. In the southeastern region, patterns that reflect design elements were extracted by applying safe, lively, and peaceful colors with the design motif of curves that blend nature and agriculture. In the southwestern region, design pattern elements that highlight nature, history, and culture were extracted with various cultural assets and natural greenery as motifs. Lastly, in the Saemangeum region, the ocean flow and greenery could be used as a design motif to reflect a positive, clear, future-oriented image in the design spot zones by region. Second, based on the standard design elements (design motive, color, pattern) by region extracted for the standard design development of street facilities in each region in Jeollabuk-do, an integrated zone(Form, structure, material, color, functional element) to which regional design guidelines can be applied. Third, an integrated zone (form, structure, material, color, functional elements) was composed. In addition, design spot zones (patterns and colors in city and county units) that can contain the diversity and identity of each region were designated. By designating design spot zones (patterns and colors in city and county units) that can contain the diversity and identity of each region, standard design development plans (integrated pillars, jaywalking prevention fences, roundabouts (urban type, rural type), street trees) Eight standard designs, including protective covers, street planters, flat benches, light benches, visual media for user guidance, and parking zones for personal mobile devices) were presented.

  • 2007년부터 2009년까지 3년동안 진주시 정촌면 예하리 강주연못 주위 꽃길 전시포에 재배되고 있는 둥글레 잎에서 갈색점무늬 증상이 심하게 발생하였다. 병징은 붉은색의 작은 점무늬 병반이 생기고 진전될 경우 담갈색 또는 검은 갈색의 2~8 mm 정도 크기의 타원형 또는 부정형의 병반을 형성하고 심하게 발생할 경우 잎이 시들고 말라 죽었다. 병반부위나 PDA배지 표면에 검은색의 작은 분생포자각이 형성되었다. 균사생육 적온은 $20\sim25^{\circ}C$이었다. 병포자의 모양은 구형 또는 아구형으로 무색이며 크기는 $10\sim18{\times}5\sim12{\mu}m$이었고 부속사가 부착되어 있으며, 크기는 $4\sim15{\mu}m$이었다. 분생포자각의 모양은 구형으로 검은색이며 크기는 $60\sim162{\times}70\sim174{\mu}m$이었다. 지금까지 둥글레에 발생한 병징과 병원균의 균학적 특징 및 병원성을 검정한 결과, 이 병을 phyllostieta crurnta (Kunze:Fries) Kickx에 의한 풍굴레 갈색점무늬병으로 명명 하고자 제안한다.

  • Sclerotinia homoeocarpa F.T. Bennett에 의한 동전마름병은 북미에서 가장 흔하며 경제적으로 중요한 잔디병이다. 동전마름병을 관리하기 위해서는 봄부터 가을까지 잦은 약제처리를 요구한다. 본 연구에서는 동전마름병에 대한 농약의 단용 혹은 다른 약제와의 혼용 처리를 통해 약제의 효과를 평가하고, Rhizoctonia solani에 의한 브라운 패치(brown patch)와 Pythium aphanidermatum에 의한 피시움마름병에 대한 이차 방제효과(secondary effect)도 조사하였다. 평가기간동안 동전마름병은 유리한 기상조건으로 인하여 평가하기에 적당한 병 발생을 보였다. 처리한 살균제 중 Rhapsody 단용처리를 제외한 모든 살균제의 단용 혹은 혼용처리에서 동전마름병에 대한 유의성 있는 방제효과가 인정되었다. 또한 동일한 처리구에서 브라운 패치에 대한 병 방제효과도 인정되었다. 모든 살균제에서 약해는 관찰되지 않았다.

  • The spot welds of Transformation Induced Plasticity (TRIP) steels are prone to interfacial failure and narrow welding current range. Hard microstructures in weld metal and heat affected zone arenormally considered as one of the main reason to accelerate the interfacial failure mode. There fore, detailed observation of weld microstructure for TRIP steels should be made to ensure better weld quality. However, it is difficult to characterize the microstructure, which has similar color, size, and shape using the optical or electron microscopy. The atomic force microscope (AFM) can help to analyze microstructure by using different energy levels for different surface roughness. In this study, the microstructures of resistance spot welds for AHSS are analyzed by using AFM with measuring the differences in average surface roughness. It has been possible to identify the different phases and their topographic characteristics and to study their morphology using atomic force microscopy in resistance spot weld TRIP steels. The systematic topographic study for each region of weldments confirmed the presence of different microstructures with height of 350nm for martensite, 250nm for bainite, and 150nm for ferrite, respectively.

  • 칼라 CTR(cathode ray tube) 모니터의 빔 전류와 화면위치를 변화시키면서 misconvergence, 스폿 크기, 디스플레이 휘도, 색도 좌표를 측정하였다. 일차원 CCD(charge coupled device)를 사용하여 misconvergence를 측정하였으며, 시감효과를 고려하는 SQRI(square-root integrals)를 도입하여 분해능을 나타내었다. 모니터의 miscovergence는 빔 전류에 영향을 받지 않고 화면의 위치에 따라 변하였으며, 화면 주변부에서의 misconvergence는 분해능을 저하시켰다.

  • We report the first occurrence of Ophichthus erabo (Jordan and Snyder, 1901) collected in the waters around Jeju Island. The morphologic characteristics of this species include rich brown semicircular spots distributed on the head, the back, and the dorsal fins. Ophichthus erabo has a similar body color to Ophichthus polyophthalmus but can be clearly distinguished from the latter by the number of vertebrae (152-155 in O. erabo vs. 147-149 in O. polyophthalmus) and the existence of a white spot at the center of a semicircle (i.e., no white spot in O. erabo vs. a white spot in O. polyophthalmus). We suggest a new Korean name for O. erabo to be "Mul-bang-ul-ba-da-baem-gang-eo".

  • The effects of LET (linear energy transfer) of radiation on the induction of somatic chromosome mutations or gene mutations of Drosophila melanogaster were studied. For detecting somatic chromosome mutations and gene mutations, Drosophila wing spot system and eye-color spot system were used, respectively. The frequencies of somatic chromosome mutations or gene mutations induced after third instar larval treatment with 23 MeV neutrons, thermal neutrons, X-rays were examined. From these data, the RBE(relative biological effectiveness) values of 23 MeV neutrons relative to X-rays for induction of somatic chromosome mutations or gene mutations were calculated. The present results suggest that high LET radiations are efficient than X-ray in producing not only somatic chromosome mutations but also gene mutations.

  • In 1991, the leaf brown spot of ivy-aureus (Scindapsus aureus) was found in Taejon and Seoul, Korea. The symptoms were appeared as dark-brown spots. The lesions were often surrounded by yellowish halos. These spots were enlarged to circular or elliptical in shape and dark-brown to black in color with slightly elevated in margin and sunken in center. The pathogenic bacteria were isolated from the diseased leaf of ivy-aureus were identified as Erwinia chrysanthemi on the basis of bacterial characteristics therefore, we would like to propose to the name of ivy-aureus disease caused by E. chrysanthemi as“bacterial brown rot of ivy-aureus”hereafter.

  • This paper proposes an efficient method to locate the automated guided vehicle (AGV) into a specific parking position using artificial visual landmark and vision-based algorithm. The landmark has comer features and a HSI color arrangement for robustness against illuminant variation. The landmark is attached to left of a parking spot under a crane. For parking, an AGV detects the landmark with CCD camera fixed to the AGV using Harris comer detector and matching descriptors of the comer features. After detecting the landmark, the AGV tracks the landmark using pyramidal Lucas-Kanade feature tracker and a refinement process. Then, the AGV decreases its speed and aligns its longitudinal position with the center of the landmark. The experiments showed the AGV parked accurately at the parking spot with small standard deviation of error under bright illumination and dark illumination.

  • Undesired reflection removal from an image captured through glass window is widely needed with the prevalence of camera. In this paper, we present and implement a reflection removal algorithm, which is specially designed for smart devices. Our implementation requires smart phone application to take two input pictures of the same target, one with flash light on and another with flash light off. Then, we find a flash spot in the picture, match the features to align the input pictures, transform the color space, and finally combine the pictures. As the result, we get a resulting image with removed reflection, achieving the visually pleasant.
