      • 망이산성 출토유물의 성격

        권상열,윤종균,성재현 한국고고미술연구소 2005 고고학지 Vol.14 No.-

        충북 음성군 망이산성(望伊山城) 출토유물은 2001년 12월 국립청주박물관에 신고된 발견매장문화재이다. 국립청주박물관에서는 출토지에 대한 현지조사를 실시하였으나, 신고지는 이미 약수터의 휴식공간으로 정지되어 있어 유구 및 출토상황을 전혀 확인할 수 없었다. 출토유물들은 산성 내 봉수대의 남쪽 경사면 아래에서 발견되었으며, 철제갑옷을 비롯하여 철부(鐵釜), 주조철부(鑄造鐵釜), 토기편 등이 함께 출토되었다. 이 가운데 철제갑옷은 그 동안 백제지역에서 출토예가 매우 드물었던 무구류의 하나로서, 더구나 보존상태가 양호하여 거의 원형을 유지하고 있다는 점에서 학술적 가치가 대단히 높은 것으로 생각되며 나머지 유물 역시 유적의 성격이나 지역 역사를 이해하는데 있어 고고학적으로 중요한 자료라 생각된다. Artifacts were discovered from the Mangyi mountain fortress (Yangdeok-ri, Eumseong county, North Chungcheong province) during construction of a resting place near a mountain-hiking trail. The retrieved artifacts include iron armor, iron pot, iron axe, clamps, and potsherds. The Mangyi mountain fortress is located in the central inland region of the Korean peninsula, which is considered the central place in transportation. The fortress also commands a fine view over a large area and sits on a location that had been strategically important since the Three-Kingdoms period until the Chosun period. Excavations at the location have revealed Baekje pottery, as well as artifacts dated to the Unified Silla period and the Goryeo period. Remains of the Baekje earthen fortress also deserve recognition. The artifacts being introduced in this paper, along with those already reported, provide important archaeological information that not only sheds light on the Mangyi mountain fortress itself, but also on the regional history. Although contextual information of the artifacts and the associated archaeological features have not been reported well due to the construction project at the site, we conclude that these artifacts are dated from the fourth to the fifth century AD. based on stylistic features. In addition, it should be emphasized that the discovery of iron armor is almost unprecedented in the Baekje region. The iron armor found at the site is very important in studying ancient weapons and their development over time. The cast-iron axe, clamps, and potsherds are stylistically similar to those found in the neighboring regions. Through these artifacts, we will be able to study the political situation of the region during the Three-Kingdoms period. The primary importance of the artifacts discovered from the Mangyi mountain fortress lies in their contribution to the studies of regional history.

        Effect of Partial Replacement of Green Grass by Urea Treated Rice Straw in Winter on Milk Production of Crossbred Lactating Cows

        Sanh, M.V.,Wiktorsson, H.,Ly, L.V. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.4

        Fresh elephant grass was replaced by urea treated rice straw (UTRS) to evaluate the effects on milk production of crossed lactating cows. A total of 16 crossbred F1 cows (Holstein Friesian ${\times}$ Vietnamese Local Yellow), with a body weight of about 400 kg and lactation number from three to five, were used in the experiment. The experimental cows were blocked according to the milk yield of the previous eight weeks and divided into 4 homogenous groups. The experiment was conducted with a Latin Square design with 4 treatments and 4 periods. Each period was 4 weeks, with 2 weeks of feed adaptation and 2 weeks for data collection. The ratio of concentrate to roughage in the ration was 50:50. All cows were given constant amounts of elephant grass dry matter (DM), with ratios of 100% grass without UTRS (control treatment 100G), and 75% grass (75G), 50% grass (50G) and 25% grass (25G) with ad libitum UTRS. Daily total DM intake on 100G, 75G, 50G and 25G was 12.04, 12.31, 12.32 and 11.85 kg, and the daily ME intake was 121.6, 121.5, 119.4 and 114.3 MJ, respectively. The daily CP intake was similar for all treatments (1.85-1.91 kg). There was a difference (p<0.05) in daily milk yield between the 25G and the 100G and 75G (11.7 vs. 12.6 and 12.5 kg, respectively). Milk protein concentration was similar for all treatments, while a tendency to increased milk fat concentration following the increase of UTRS ratio was observed. The cows gained 4-5 kg body weight per month and showed first oestrus 3-4 months after calving. The overall feed conversion for milk production was not affected by ratio of UTRS in the ration. It is concluded that replacement of green grass by UTRS with a ratio of 50:50 for crossbred lactating cows is as good as feeding 100% green grass in terms of milk yield, body weight gain and feed conversion. UTRS can preferably replace green grass in daily rations for crossbred dairy cows in winter to cope with the shortage of green grass, with the ratio 1:1.

        Effects of Natural Grass Forage to Concentrate Ratios and Feeding Principles on Milk Production and Performance of Crossbred Lactating Cows

        Sanh, M.V.,Wiktorsson, H.,Ly, L.V. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.5

        Two experiments were conducted to evaluate the effects of forage:concentrate ratios and feeding principles on milk yield, milk composition, body weight change, postpartum oestrus and feed cost. A total of 36 crossbred F1 cows (Holstein Friesian${\times}$Local Yellow) in the 8th week of lactation were used. In each experiment, animals were divided into three groups using a randomized block design according to the milk yield of the previous eight weeks. Cows were fed 30, 50 and 70% concentrate in the diet based on DM. In experiment 1 (Fc), cows were given the same amount of DM with constant ratios of forage and concentrate within treatments. In experiment 2 (Fa), cows were given the same constant amounts of concentrate as in experiment 1 and ad libitum forage. The forage consisted of a natural grass mixture based on 5 species of grasses with high nutritive values. There was no difference in total DM intake between treatments within experiments. However, cows fed forage ad libitum had higher DM intakes compared to cows fed constant forage (1.6, 4.5 and 9.5% for cows fed 70, 50 and 30% forage, respectively). Daily milk yield of cows fed forage ad libitum was higher than that of cows fed constant forage:concentrate ratio. Within experiment, milk yield was highest for cows fed 30% DM forage, followed by cows fed 50% and then cows fed 70% forage (11.17, 10.98 and 10.71 for the 30Fc, 50Fc and 70Fc cows; 11.73, 11.16 and 10.81 kg for the 30Fa, 50Fa and 70Fa cows, respectively). Decreased forage ratio in the diets resulted in decreased milk fat content and tended to increase milk protein. Increased concentrate ratio in the diet and feeding forage ad libitum increased body weight gain. The effect of forage:concentrate ratio on postpartum oestrus was not significant. The feed cost per kg milk produced was lowest for the cows fed 70% forage. It is concluded that increased ratio of concentrate resulted in increased body weight gain, milk yield, milk protein, and decreased milk fat. Feeding forage ad libitum increased feed intake, milk yield and body weight gain. The ratio of 50% forage is more suitable for milk production and animal condition, but in terms of feed cost and under the conditions of small dairy farmers, the 70% ad libitum forage feeding is recommended.

      • 도시재생 수단으로서 스포츠공간 활용에 관한 연구

        신상현 ( Shin Sanh-hyun ),맹이섭 ( Maeng Lee-seob ) 인천대학교 스포츠과학연구소 2016 스포츠科學硏究誌 Vol.29 No.0

        본 연구에서는 이러한 도시재생의 수단들 중에서 스포츠가 지니는 도시재생 기여정도를 설명하고 그 다음 성공적인 도시재생을 이룬 해외사례들을 통해서 한국의 도시재생에 있어서 그 적용 가능성을 제안해 보고자 한다. 도시재생 수단으로서 스포츠의 기여에 대한 해외사례를 정리해 보면 크게 올림픽 등 메이저 국제스포츠 이벤트의 유치와 이를 위한 시설물 개발 및 관련시설 투자 유형, 도시의 중심시가지가 그 중심성을 상실하는 공동화현상에 대응하여 중심시가지의 구심성을 재확보 하는 유형, 주요 국제 관광지로서 기득권을 확보하고 있는 도시들이 메이저 국제 스포츠이벤트를 유치하여 도시 브랜드를 높인 유형의 3가지로 구분해 볼 수 있다. 한국에서도 스포츠를 활용하여 지역개발과 도시 활력을 제공한 사례들이 많은데, 고양, 수원, 평창, 남해, 영주 등이 대표적이다. 그러나 이러한 도시들은 도시의 빈민지역 개발, 도시공동화 해소 등 다양한 도시문제를 해결하기 위한 방안인 도시재생 차원에서 이루어졌다고 보기는 어렵다. 이러한 차원에서 본 연구는 한국의 사례로 든 지역에 대하여 도시재생 차원에서의 선진사례를 적용하여 사례지역의 도시문제 정의, 도시문제 해결 방안으로서 스포츠의 기여, 다양한 도시문제 해결을 위한 맞춤형 스포츠수단 투입 등을 벤치마킹할 필요가 있다. This study is to explain contribution of urban regeneration which sports nave among these means of urban regeneration, and then to see the application possibility of urban regeneration in Korea through international examples in successful urban regeneration. To sum up the international cases of contribution of sport as a means of urban regeneration, facilities development and a type of facilities investment for Olympic and a major international sport event, in response to urban doughnut phenomena with loss of the centrality in the center of the city, resecuring the centrality of the center of the city, as a major international tourist destination, cities with a vested interest which hold a major international sport event can be divided into three types to see it raised city brand. There are many cases in Korea utilizing sports in local development and urban vitality where Goyang, Suwon, Pyeongchang, Namhae, and Yeongju are the typical example. But, these cities cannot be seen to solve various problems in city, such as slum area development and resolution of urban doughnut phenomena for the urban regeneration dimension. In this aspect, this study needs benchmarking that an international case can be used to define city problems in the case area as a case of korea, contribution of Korea as an urban problem solution, input a customized sport means for solving a variety of urban problems.

        Effects of Supplementation of Mixed Cassava (Manihot esculenta) and Legume (Phaseolus calcaratus) Fodder on the Rumen Degradability and Performance of Growing Cattle

        Thang, C.M.,Sanh, M.V.,Wiktorsson, H. Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.1

        Two experiments were conducted to assess the effect of replacing a conventional concentrate with mixed cassava (Manihot esculenta) foliage and legume (Phaseolus calcaratus) foliage. In Exp. 1, three rumen fistulated crossbred cows were used for in sacco rumen degradability studies. In vitro gas production was also studied. In Exp. 2, 11 crossbred F2 heifers (Red Sindhi$\times$Holstein Friesian), with initial live weight of $129{\pm}6kg$ and aged six months, were allocated in a Completely Randomized Design (CRD) to evaluate a mixture (ratio 3:1) of cassava and legume foliage (CA-LE feed) as a protein source compared to a traditional concentrate feed (Control) in diets based on fresh elephant grass (Pennisetum purpureum) and urea treated rice straw ad libitum. The Control feed was replaced by the CA-LE feed at levels of 0% (Control), 40% (CA-LE40), and 60% (CA-LE60) based on dry matter (DM). The in sacco degradation of CA-LE feed was higher than Control feed (p<0.05). After 48 h incubation the degradation of CA-LE feed and Control feed was 73% vs. 58% of DM and 83% vs. 65% of CP, respectively. The gas production of CA-LE feed was also significantly higher than of Control feed during the first 12 h of incubation. The results of the performance study (Exp. 2) showed that the level of CA-LE feed in the concentrate had no effect on total dry matter intake (p>0.05), but live weight gains (LWG) in CA-LE40 and CA-LE60 were significantly higher (551 and 609 g/d, respectively) than in the Control group (281 g/d). The intake of CP was higher (p<0.05) for the treatments CA-LE40 and CA-LE60 (556 and 590 g/d, respectively) compared to that of Control (458 g/d), while there was no significant difference in ME intake. The feed conversion ratio was 16.8, 9.0 and 7.9 kg DM/kg LWG in Control, CA-LE40 and CA-LE60, respectively. The feed cost of CA-LE40 and CA-LE60 corresponded to 43% and 35%, respectively, of the feed cost of Control feed. The best results were found when CA-LE feed replaced 60% of DM in Control feed and considerably decreased feed cost. It is concluded that feeding cassava foliage in combination with Phaseolus calcaratus legume as a protein supplement could be a potentially valuable strategy which leads to reduced feed costs and a more sustainable system in smallholder dairy production in Vietnam.
