  • The confidence of information from image processing depends on the original image quality. Enhancing the confidence by an algorithm has an essential limitation. Especially, road images are exposed to lots of noisy sources, which makes image processing difficult. We, in this paper, propose a FNN (fuzzy-neural network) capable oi deciding the quality of a road image prior to extracting lane-related information. According to the decision by the FNN, road images are classified into good or bad to extract lane-related information. A CDF (cumulative distribution function), a function of edge histogram, is utilized to construct input parameters of the FNN, it is based on the fact that the shape of the CDF and the image quality has large correlation. Input pattern vector to the FNN consists of ten parameters in which nine parameters are from the CDF and the other one is from intensity distribution of raw image. Correlation analysis shows that each parameter represents the image quality well. According to the experimental results, the proposed FNN system was quite successful. We carried out simulations with real images taken by various lighting and weather conditions and achieved about 99% successful decision-making.

  • Two dogs (case 1:2-year-old intact male German Shepherd-mixed dog and case 2: 4-year-old intact female Jindo miked) with perineal hernia were referred to the Chonbuk Animal Medical Center, Chonbuk National University. In the both cases, there were unilateral perineal swelling involving the right side of the anus. In addition, in case 2, swelling was also present ventral to the anus. Rectal palpation of pelvic diaphragm revealed weakness of the muscles. Both cases were surgically treated using muscle transposition technique for hemiorrhaphy. In case 1, transposition of the superficial gluteal and internal obturator muscles and in case 2, transposition oi semitendinosus muscle was performed for hemiorrhaphy and reconstruction of the pelvic diaphragm. Both dogs became recovered after the surgical correction and no complications were observed during 10-month (casel) and 9-month(case2). Muscle transposition can be a useful technique for the treatment of perineal hernia in the dog.

  • The purpose of this study was to provide basic information about the usage frequency of foods and menu items that may have microbiological hazards in elementary school foodservice operations in order to prepare a sanitation management manual for the foodservice production process. Menus from 200 elementary school foodservice operations from June 2004 were analyzed. An analysis of the foodservice production process of the menu revealed that the following processes were used: heat process(63.9%), non-heating process(28.1%), and after-heating process(8.0%). The cooking methods used for side dishes were: Stir-frying(19.9%), Saenchae(15.6%), Jorim(15,1%), Sukchae(13.1%), Frying(11.3%) and so on. Overall, 85 menu items known to include microbiological hazards were offered a total of 3,537 times; they were Doegi-bulgogi(7.0%), Bibim-bap(5.2%), Oi-saengchae(4.6%), Kongnamul-muchim(4.2%), Ddeok-bokkeum(4.0%), Japchae(3.7%), and so on. To serve safe and hygienic foods, menus including microbiological hazards should be planned very carefully. Furthermore, if a menu is high in microbiological hazards and frequency, the manuals of sanitation management should be applied more thoroughly.

  • The purpose of this study was to investigate the effects of an after-school cooking program on the eating habits and sociality of children. Thirty five children from the 3rd to the 6th grade of G Elementary School participated in this program comprising 12 periods of cooking activities, from May to August 2013. The content of the after-school cooking program included japchae, topokki, jajangmyeon, oi sobagi, cake, snack wrap, vegetable fried rice, sticky noodle, sushi, pizza, rice muffin, and sandwiches. Before and after learning, the participants' eating habits and sociality were investigated. The study analyzed the mean, standard deviation, and Wilcoxon Matched-Pairs Signed-Ranks Test results for a comparison between the pre- and post-test results. On the basis of the research findings and discussions, the study reached the following conclusions. First, the after-school cooking program was analyzed as being helpful and useful in categorizing the eating habits of children as sanitary dietary life, well-mannered dietary life, and healthy dietary life. Further, more girls than boys fostered effective eating habits. Second, the after-school cooking program was analyzed as being helpful and useful in determining sociality and more girls than boys fostered effective sociality. Third, cooking is an appropriate topic for the after-school program of Korean elementary schools, and the cooking program has expanded in G Elementary School after the abovementioned experiment.

  • Gravity waves have been searched for with a new all-sky camera system over Korean Peninsular. The all-sky camera consists of a 37mm/F4.5 Mamiya fisheye lens with a 180 dog field of view, interference filters and a 1024 by 1024 CCD camera. The all-sky camera has been tested near Daejeon city, and moved to Mt. Bohyun where the largest astronomical telescope is operated in Korea. A clear wave pattern was successfully detected in OH filter images over Mt. Bohyun on July 18, 2001, indicating that small scale coherent gravity waves perturbed OH airglow near the mesopause. Other wave features are since then observed with Na 589.8nm and OI 630.0nm filters. Since a Japanese all-sky camera network has already detected traveling ionospheric disturbances (TID) over the northeast-southwest range of Japanese islands, we hope our all-sky camera extends the coverage of the TID's observations to the west direction. We plan to operate our all-sky camera all year around to study seasonal variation of wave activities over the mid-latitude upper atmosphere.

  • Mancozeb (MCZ), a polymeric complex of zinr and manganese salts of ethylene bisthiocarbamate, is widely used in agriculture as fungicidel, insecticides, and herbicides. MCZ can be occupationally and environmentally exposed to human and has been reported to have detrimental effects on the reproductive system, but the toxicity of MCZ on immune responses has not been systematically investigated. We investigated the effects of MCZ exposure on the activities of murine splenocytes through evaluation of splenocytes cellularity and INF-$\gamma$ synthesis. Splenocytes were examned ex vivo from mice orally treated with various doEes of MCZ for 1 day (acute exposure, 2,100, 5,000, 10,000 mg/kg) or ior 5 consecutive days per week for 4 weeks (subacute exposure,250, 1,000, 1,500 mg/kg/day) fellowed by culture for 2 days in the presence of Con A or PHA plus IL-2. Splenocytes Iron naive mice were cultured with various concentration of MCZ (50, 500, 1,000 ng/ml) in the presence of Con A or PHA plus IL-2 for 2 days in vitro. IFN-$\gamma$ production was decreased with the in vitro exposure to all concentration of MCZ. The spleen cellularity and IFN -$\gamma$ production by splenocytes from MCZ -acutely and - subacutely exposured mice were decreased in comparision with that oi control group.

  • A groung Fabry-Perot interferometer has been used to measure atomic oxygen nightglow (OI 630.0nm) from the thermosphere (about 250km) at King Sejong station (KSS, geographic: $62.22^{\circ}$S, $301.25^{\circ}$E; geomagnetic: $50.65^{\circ}$S, $7.51^{\circ}$E), Antarctica. While numerous studies of the thermosphere have been performed on high latitude using ground-based Fabry-Perot interferometers, the thermospheric measurements in the Southern Hemisphere are relatively new and sparse. Therefore, the nightglow measurements at KSS play an important role in extending the thermospheric studies to the Southern Hemisphere. In this study, we investigated the effects of the geomagnetic and solar activities on the thermospheric neutral temperatures that have been observed at KSS in 1989 and 1997. The measured average temperatures are 1400K in 1989 and 800K in 1997, reflecting the influence of the solar activity. The measurements were compared with empirical models, MSIS-86 and semi-empirical model, VSH.
