Purpose: We evaluated the results of surgical treatment for metastatic pathologic or impending pathologic fractures. Materials and Methods: From January 2004 to December 2007, 18 patients 19 cases were included. Male were 6 and female were 12. The mean age was 65.1. Mean follow up period was 15.2 months. Pathologic fractures were 14 and impending pathologic fractures were 5. MSTS score, periodic radiologic follow up and postoperative complications were evaluated. Results: The primary malignancies were 6 cases of multiple myeloma, 4 cases of renal cell carcinoma, 2 cases of cholangiocarcinoma, 2 cases of colon cancer, 2 cases of breast cancer and 2 cases of leiomyosarcoma. Metastatic lesions were 10 cases of femur, 4 cases of clavicle, 2 cases of humerus, 2 cases of tibia and 1 case of radius. Surgical options were curettage, cementation, internal fixation and arthroplasty. Mean MSTS score was 15.9. Postoperative complications were 1 case of infection, 1 case of local recurrence and 1 case of implant loosening. Ten patients were alive with disease, 8 patients died of disease. Conclusion: Surgical treatment of metastatic skeletal lesions allowed early ambulation and improving dexterity. It improved pain and emotional acceptance. Surgery is necessary for improving qualities of remaining lives.
Mongolia has 80% livestock of total agriculture industry, 170,000 farms are engaged, 2,500,000 of cows that were beef and dairy cows are raised. Despite of Mongolian has great application with milk, there are not clear differences between cow and dairy cattle, and the production of milk is also low. But the milk suppliers are varied (horse, sheep, goat, etc), so that the total milk production is 500 thousand ton per year. It's really considerable to improve the breed of owing to many problems with big differences among milk qualities. For carrying out for first year project, artificial insemination project was operated with 3rd grade Holstein semen that were imported from S. Korea, and initiation and field training were also carried out through appropriate AI technique we developed for Mongolia environment. Local information research and MOU conclusion were done with professor D. Altangerel in May $10^{th}{\sim}13^{th}$, 2009, and development for AI technique and AI equipments were supplied for Mongolia breeding and natural environment in July $10^{th}{\sim}17^{th}$ in 2009. All cows were treated by synchronization for AI. To do this, $PGF_{2\alpha}$ injection were treated for luteal phase cow, if it wouldn't work, try again after 11 days. After confirmation of estrus, AI and AI training were carried out with sperm injection in the uterus or cervix by rectum-vagina method which is common worldwide, the most effective artificial insemination technique. If cows were return to next estrus cycle, second AI was carried out about approximately 21 days after artificial insemination. After 2 months, all cows not showing return estrus should be taken pregnancy test. Every pregnant cow will be cared thoroughly. Total 48 cows administrated by $PGF_{2\alpha}$ for synchronization and after 48 hours 45 cows (93.8%) showing estrus were detected and then artificial inseminate them within who 8 cows (27.8%) showed return estrus. Therefore, Using $PGF_2{\alpha}$ for synchronization is effective to use for Mongolia breeding conditions. There are possibility of base for food production after all, including increase of livestock production in Mongolia by improvement of breeding cow with AI and embryo transfer project.

This study was conducted in the summer of 2005 in Shindong-myeon, Chuncheon-si, Gangwon-do to assess the quality of drinking water and to evaluate their potential pollutants. Ninety four water samples were collected from three classes of water supplies such as simple piped water, supplied own water and others (Supplied local water). Most residents used simple piped water (72.63%). 31.25% residents thought the water quality was bad and landfill was the main source of pollution that affected water quality. To correspond this perception, water quality was measured according to Drinking Water Quality Standard. The general bacteria, coliforms, and $NO_3-N$ exceeded the standard but the water qualities in these four areas were suitable for Drinking Water Quality Standard. The simple piped water showed low mean concentration of excess rate compared to supplied own piped water except general bacteria. Hardness, pH, and $NO_3-N$ showed significantly higher effects on drinking water quality. To evaluate the effect of effluent from landfill, water quality was measured according to distance and altitude. However, there was no effect of landfill effluent. To find out the effect of rainfall, we compared water quality of the year 2003 with that of 2005. The result showed significant differences in hardness and $NO_3-N$ concentration. This study confirmed that $NO_3-N$, coliforms, and general bacteria are main pollutant of water supply in rural community. Therefore, it is necessary to regularly maintain simple piped water supply, supplement sewer facilities, and educate residents about public health risk associated with drinking water in rural area.
Film festival is a cultural event, which would be held for various purposes. This study was to find out the effects of visitors' demographic characteristics and Jeonju International Film festival images upon their general satisfactions, focusing on the 10th Jeonju International Film Festival. The results are as following. First, 20's(year), Student(job) and Less than 100(income/a month) had a majority in the demographic characteristic. It is needed to develop various programs and events targeting for these groups. Second, it resolved 11 questions in all into 3 factors, which is named as 'Administration', 'Facility', and 'Contents'. Specially We need to develop events and programs for teens. It verified that visitors satisfied far more as they were provided with comfortable theater, various facilities and events, etc. It also proved that the service of giving useful informations met visitors' satisfaction. But as the demographic characteristic showing, visitors dwelling near Jeonju were fewer. It is required for a program to enhance the peculiar qualities of the city, Jeonju and then to promote the participation of local people. It is necessary for the host organization to secure its identity including peculiar subjects differentiated from other film festivals for the purpose of establishing itself as a worldwide event.
The purpose of this study is to examine the influence of the village gut (shamanic ritual) Dangsanje and Nong-ak (agricultural musical ritual) in the Jeong-eup Province on the formation of the ideology of the Jeungsan (甑山), Kang Il-sun (姜一淳 1871~1909), a thinker from Jeong-eup. As a result, this article has reached the following conclusions: first, the ideas of a certain thinker are influenced by the local culture in which they were born and raised. Second, the central area where Kang Jeungsan was born, grew up, and later developed his system of philosophical thought was the Jeong-eup Province. Third, in Jeong-eup, Nong-ak is traditionally accompanied as a necessary requirement. Fourth, the Nong-ak that Kang Jeungsan witnessed in his hometown during his lifetime had those qualities. Fifth, Kang Jeungsan empirically identified the close interrelationship between Village Gut Dangsanje, Nong-ak, and Mudanggut from an early age. Sixth, this aspect of influence is tangibly reflected in the words and actions he left behind. Seventh, Kang Jeungsan's experience of Jeong-eup Nong-ak was recreated in the religious music of Bocheonism, where his ideas were formulated into an organized religion for the first time. Eighth, this process of religionizing Nong-ak in Bocheonism greatly influenced later Jeong-eup Nong-ak and also Honam Nong-ak more generally.

In this study we investigated the effect of a floating photovoltaic (FPV) system in Cheongpung Lake on water quality. The FPV with a tilt angle of 33° covered ca. 0.04% of surface area (97 ㎢) of Chungju Lake. The water qualities of the whole lake before and after installation of FPV were first compared. DO, BOD, TOC, and Chl-a of the whole lake were increased, while conductivity decreased after installation period at the significance level of 0.05. This change was probably due to the increased influx of nutrients by 40% resulting from increased precipitation during the same period. We also measured water quality parameters on May and Nov. 2017 at the FPV center (FPVC) and nearby control sites, and compared water quality. The result showed that the FPVC and nearby sites were not significantly different (p>0.05), demonstrating that the FPV does not cause a decline of water quality. The water temperature, light intensity, and phytoplankton community were also measured. The water temperature was not different between the sites, while the light intensity decreased to 27~50%. Despite reduced light intensity at FPVC, the phytoplankton standing crops and the number of species were not significantly different (p>0.05). However, in the early November samples, standing crops was significantly higher in FPVC than control with periphytic diatoms belonging to Aulacoseira genus being dominant. This may be due to the temporal water body behavior or local retention of current by FPV system. This study may provide a measure of future installation of a FPV system.
''Nokyang', a new high biomass yield and whole crop silage rice (Oriza sativa L.) cultivar, was developed by the rice breeding team of National Institute of Crop Science, RDA, Suwon, Korea, during the period from 1996 to 2006 and released in 2007. It was derived from a cross between Yongmoonbyeo/IR67396-16-3-3-1. This cultivar has about 130 days of growth duration from seeding to heading and is tolerance to lodging with erect pubescent leaves, semidwarf (culm length 78 cm) and thick culm. This cultivar has less tillers per hill and more spikelet numbers per panicle than Dasanbyeo. 'Nokyang' has wide and stay green leaf compared other Tongil-type varieties. This new variety is resistant to grain shattering and to some disease including bacterial leaf blight and stripe virus. This variety has good qualities for whole crop silage with high TDN (Total Digestive Nutrient) yield and low NDF (Neutral Detergent Fiber) and low ADF (Acid Detergent Fiber) and high RFV (Relative Feed Value) compared to common high grain yield varieties. The biomass and TDN yield performance of 'Nokyang' is 1,652 MT/ha, 9.9 MT/ha, individually in local adaptability test for three years. 'Nokyang' is adaptable to central plain area, south-eastern plain area of Korea.

This study was undertaken to investigate whether the local Woori black pigs could replace Duroc as the terminal sire in order to reduce foreign currency outgoings. This study compared the physicochemical properties of pork loins in two cultivars of three-way crossbred pigs: Landrace ${\times}$ Yorkshire ${\times}$ Duroc (LYD) and Landrace ${\times}$ Yorkshire ${\times}$ Woori black pig (LYW). A total of 119 pigs (59 LYD and 60 LYW) aged 180 days were used in the experiment. After 24 hours of cooling, pork loins were assessed for their physicochemical traits, meat color, fatty acid and sensory evaluation. The moisture content and water holding capacity showed no significant difference between the two cultivars. Fat content and cooking loss were significantly higher in LYW than in LYD (p<0.05), whereas shear force and pH were significantly lower in LYW than LYD (p<0.05). Redness ($a^*$), yellowness ($b^*$), and stearic acid (C18: 0) content were also significantly higher in LYW than in LYD (p<0.05). Sensory evaluation revealed significantly higher meat color and flavor in LYW than LYD (p<0.05). Taken together, these results indicate that certain physicochemical qualities are improved in the LYW cultivar, as compared to LYD. Therefore, Woori black pig (W) has the potential to be substituted for Duroc, a breeding pig used currently.
Jeongeup, Jeollabuk-do, is an area that requires attention from those who study the history of Korean thought. In addition, Jeongeup is an area wherein many works were recorded for the first time in literary history. This is the case with Jeongeupsa as a style of Baekje songs and the lyrics of the noble families of the Joseon Dynasty, Sangchungok. Jeongeup is likewise the location where Choi Chi-won (857~?) was selected to serve as a local taesu (viceroy) and where a unique tradition of music and style were passed down. In this paper, the relationship between Choi Chi-won's role in the process of establishing a silent Confucian academy in Jeongeup and the emergence of scholar culture was examined. When Choi Chi-won left after his term in office, a birth shrine called Taesansa Temple was built to repay the selection of the villagers, and it became the source that led to the opening of the Confucian academy Museongseowon in the future. Jeongeup will be shown to be the location where Choi Chi-won realized his aspirations and honed his capabilities. In particular, Choi Chi-won's played a crucial role in the mid-Joseon Dynasty by supporting the construction and securing the name of Museongseowon. That is why Choi Chi-won was able to be revived as a symbolic figure in the region. In addition, it can be seen that the shape of Choi Chi-won was more sedentary- in the form of a Confucian scholar- and Confucian scholars emphasized the transfer of portraits at Museongseowon. Through the poetry written by Choi Chi-won, readers can learn about the worries and perceptions of scholars during those times. Although his value in the field of poetry is diverse, he can especially be recognized as a Confucian intellectual. In a large number of his works, he expresses his anxiety, agony, and critical inner consciousness all of which came from his encounter with the realities of his time. In fact, Choi Chi-won showed his qualities as a prominent literary figure of his time who had extraordinary aspirations and an admirable work ethic. However, he failed to overcome his regional and mental alienation as a poet in neighboring countries. Therefore, he internalized a sort of fierceness in terms of his perception of the world. However, it seems that it was rather a factor that made his work exhibit a strong lyrical style. In addition, Choi Chi-won's collection of writings includes a number of works that strongly criticized various forms of pathological phenomena caused by terminal phenomena of the time. He also highlighted the wrong in society by realistically depicting the lives poor and needy people and their eventual sacrifice via distorted relationships. This can be read encapsulating the agony of intellectuals of that time. The dictionary definition of a 'Confucian scholar' is "a Confucian term referring to a person or class that embodies Confucian ideology," and in its contemporary meaning it suggests " ⋯ an example of a personality, but not an identity, and the conscience of one's time period as a source of human morality inwardly and social order outwardly." In this respect, it could even be said that Choi Chi-won could be considered the originator of scholar culture.
