This experiment was conducted to evaluate agronomic characteristics, forage quality and dry matter (DM) yield of early-maturing hairy vetch 'Cold green', 'Haymaker plus', 'Cappello' and medium-late maturing cultivar 'Cheong pa', 'Challenger', 'Hungvillosa' and 'Latigo' at Seongju in the Kyeongbuk from 2009 to 2011. The experiment was arranged in randomized complete block design with three replications. Hairy vetchs were seeded on Sep. 26 and Oct. 11 in 2009 and 2010. Vetch plants were harvested on 30 Apr. in 2010 and 2011. Cold tolerance for Haymaker plus and Cappello were a little lower than other cultivars. Fifty percent-flowering dates of Cold green had earlier than others and Haymaker plus and Cappello were earlier than Cheong pa, Challenger, Hungvillosa and Latigo. Cheong pa and Challenger were ealirer than Hungvillosa and Latigo. The DM yield of Cold green was the highest (p<0.05) of the cultivar except Haymaker plus. Haymaker plus was higher (p<0.05) than others and Cappello, Cheong pa, Challenger were higher (p<0.05) than Hungvillosa and Latigo in 2010. In 2011, the DM yield of Cold green was the highest (p<0.05) of the cultivar and Haymaker plus was higher (p<0.05) than others. Cappello was higher (p<0.05) than Hungvillosa and Latigo. Cheong pa and Challenger were higher (p<0.05) than Latigo. Vetch cultivar was high in crude protein (CP) and low in Acid detergent fiber (ADF). According to the results obtained from this study, it is suggested that early-maturing cultivar would be recommendable for fall sown vetch for DM production.

Rural area development projects are being carried out in a strategy to create new value in agriculture and farm villages and to change the public perception. This study targeted rural experience participants visiting Cheong-Ho region, where the Rural Village Comprehensive Development Project was carried out. They were surveyed about attributes of visits to farm villages to determine which attributes of the experience could influence their revisits. This study was conducted under an umbrella project conducted as per the Special Act on Life Improvement and Regional Improvement for Farmers and Fishermen. Cheong-Ho region in Buan-gun produces mulberry, organic wheat, and rice grown using environmentally-friendly agricultural practices. This region as held events offering visitors the chance to experience rural villages and mulberry farms. Survey results showed that the natural landscape of villages, village experience, and the services provided by residents had a positive relationship with the probability of revisiting the village. Also, village facilities, harmony of natural landscape, hospitality of village residents, amusement value of rural experience, and the cost for rural experience were significant attributes. Therefore, it is necessary to revitalize the rural experience program targeting rural experience participants in Cheong-Ho region through continuous and monitoring of key visit attributes and revisit factors.

The purpose of this study is to investigate the effect of SoSikCheongWool-Tang on white rats' hepatocyte damages induced by Radix Aconitine. For the study, Radix Aconitine was administered to white rats, damaging their hepatocytes, and then SoSikCheongWool-Tang was given to the rats. As a result, the following histological changes of the hepatocytes were observed through light and electron microscope: 1. Radix Aconitine damaged the congestion, necrosis and hemolysis in the liver. 2. In the six-hour control group, the cisternae of rough and smooth endoplasmic reticula were dilated or disoriented, and the attached ribosomes of rough endoplasmic reticulum were hardly observed. 3. In the three-day control group, the destruction of the nucleus as well as the damage of all the cell-organelles was observed. 4. In all the experiment groups, the rats, after given SoSikCheongWool-Tang, quickly recovered from the cytotoxicity induced by aconitine extracts. From the above results, this study has come to the conclusion that SoSikCheongWool-Tang is efficacious against the cytotoxicity induced by Radix Aconitine.

This study was performed to evaluate economic effect of the water fluoridation program in Cheong-Ju City from 1982 to 2010. To study this economic effect, this study used cost-benefit analysis methodology from eight years old to fourteen years old in Cheong-Ju City. Major findings were as follows; First, total cost of fluoridation program in Cheong-Ju City was 1,384,164,734 korean won and total benefit was 15,057,426,621 Korean won from 1982 to 2010. Second, total cost which was converted by present value 2000 year was 1,687,412,718 won and total benefit which was converted by present value 2000 year was 14,582,548,519 Korean won. Cost-benefit ratio was 8.64. Net present value which happened from 1982 to 2000 was 7,990,710,155 Korean won and cost benefit ratio was 7.47. In conclusion, by the above result, economic impact of the water fluoridation program was very effective for children in some area of Cheong-Ju city.

Patients with lumbar disc herniation are faced with lowered quality of life. For this reason, we investigated the effects of Oriental Intensive Therapy (OIT) including acupuncture, pharmacopuncture, manual therapy and herbal medicine on patients with lumbar disc herniation. Ten patients, diagnosed with lumbar disc herniation by MRI in hospital, were treated with OIT for 12 weeks. Symptoms of the patients were assessed using Verbal Numerical Rating Scale (VNRS) and Oswestry Disability Index (ODI). All patients were investigated every a week. In our results, intensity of pain was reduced after 4 weeks treatment significantly by VNRS, Quality of life has also improved after 4 weeks treatment by ODI. In conclusion, this study suggests that OIT may be effective to treat patients with lumbar disc herniation.

It is generally believed that Seonjeong-jeon and Heejeong-dang respectively served as Pyeonjeon of Chang-deok Palace in the earlier and the later period of Joseon dynasty. However, such belief is based on the concept of Pyeonjeon that emerged after the time of King Soonjo's reign(1800~1834). The concept and functions of Pyeonjeon varied among times ranging from Koryo to late Joseon dynasty. In the earlier Koryo dynasty, the word Pyeonjeon signified both "Pyeonjeon in relation to Jeong-jeon" or "Pyeonjeon as a casual office for the king". The ambiguity of the word was resolved when Bopyung-cheong and Jogye-cheong were established in the earlier Joseon dynasty. These buildings in Chang-deok Palace (and only Bopyung-cheong in Gyeong-bok Palace) held rituals related to events in Jeong-jeon, as well as their exclusive political rituals. Thus, the meaning of the term "Pyeon-jeon" became restricted to its second meaning, namely a casual building for the king's everyday office work and small banquets. However, the ambiguity reemerged from around the time of King Seong-jong's reign(1469~1494). In this period, Pyeonjeon as in relation to Jeong-jeon was often referred to as "Jeong-jeon", or "Beop-jeon" from the mid-16th century. In the 19th century, Pyeonjeon as king's casual office took over the characteristics and functions of Beop-jeon. Thus, the popular notion of "Pyeon-jeon" was newly established and passed onto nowadays.

Introduction : Kim-Young-hun (김영훈), with the pen name of Cheong-Gang (청강), was born in the late 19th century. He led an active life as an eminent Korean traditional medical scholar until the mid-20th century. He opened a Korean traditional medical clinic in the heart of Seoul and kept records of his clinical experiences. Methods : Filing of clinical records: Cheong-Gang's records, at present owned by the College of Oriental Medicine, Kyunghee University (경희대학교 한의과대학), are classified into prescription charts and medical examination charts. In this study, only the medical examination charts were filed. Results : The total number of the medical examination charts from 1915 until 1974 is 393, and the titles are sorted according to date. This paper is the first filing research on the medical examination charts.

In this paper, we describe not only extraction method of moving object by difference image but also automatic target tracking algorithm. Proposed algorithm track the moving target by the calculation of moving target's center. The results show that this algorithm can apply to practical device such as real time target tracker.
