To investigate the effect of dietary mugwort pellet on the growing performance and meat quality barrow (T1) and boar (T2) were alloted into six treatments : 1) commercial feed, 2) T1-1 and T2-1 (commercial feed supplemented with 3.0% mugwort pellet), 3) T1-2 and T2-2 (commercial feed supplemented with 5.0% mugwort pellet). They were fed experimental diets for 60 days before slaughtered. Meat samples were taken in wrap package and stored at 4$\pm$1$^{\circ}C$. Daily gain in both groups (T1 and T2) were higher than those of the control (p<0.05). Feed conversion tended to be lower in barrow group than boar group and tended to be decreased according to supplementation of mugwort pelleted diet in barrow group. In both barrow and boar groups, proximate compositions of pork were not sigificantly different, except for crude fat. Crude fat content was tended to be low in barrow when fed mugwort pelleted diet. Shear force value and sensory properties were siginificantly higher in barrow group than in boar group (p<0.05) and these results were also seemed due to great fed mugwort pelleted aiet(p<0.05). In the barrow group, values of tenderness and flavor were the highest in pigs fed diet supplemented with 3.0% mugwort. The catechin content of pork tended to be higher in boar group than in barrow group and catechin tended to increase with supplementation of mugwort in the diet.

This study was conducted to investigate the effect of different castration ages on meat quality and sensory properties of Korean native black goats over 410 days. For the experiment, 32 heads of goat (eight heads/4 treatment) were subjected to either a control (5 month non-castration), T1 (7 month castration), T2 (5 month castration) or T3 (3 month castration). The total weight gain for Korean native black goats was highest in the T2 group after feeding for 410 days and the weight gain/day tended to be similar to the total weight gain. The total feeding amounts were lowest (410.82 kg) in T3; however, the feed intake ratio was 16.39 in T2, indicating that it had the best feed efficiency among groups. The cooking loss and drip loss of the Korean native black goats was highest in the control, being 35.53% and 2.08%, respectively (p<0.05), while the total cholesterol of the treatments was higher than that of the control (p<0.05). Moreover, the overall sensory evaluation of the treatment groups was low, indicating that there was more meat flavor when compared to the controls in terms of juiciness, tenderness, flavor, texture, black goat off-flavor and overall evaluation (p<0.05). T2 was found to have the best meat flavor upon sensory evaluation. Additionally, the meat color of the control showed the highest $L^*$ value and Hue value, while T3 showed the highest $a^*$ value (3.61) and T2 showed the highest $b^*$ value and Chroma. The composition of fatty acids was 53.76% oleic acid in T2, while the amounts of Mono-unsaturated fatty acid (MUFA) were highest in T1 and T2 (p<0.05). As a result, the MUFA/SFA ratios of T1 and T2 were higher than those of the control (p<0.05). In conclusion, it is most advantageous to castrate Korean native black goats at the age of 5 months for the best performance and meat quality.

This study was conducted to determine the effect of feeding dietary mugwort on the beef quality during 14 month(from 14 month to 27 month) with 32 heads of fattening Hanwoo. Fattening Hanwoos were randomly allotted 4 treatments(8 heads/treatment): C-1[(control(0%) of Hanwoo steers)], C-2[(control(0%) of Hanwoo heifers)], T-1(supplemented with mugwort powder 2.0% of Hanwoo steers), T-2(supplemented with mugwort powder 2.0% of Hanwoo heifers). The shear force value and water holding capacity(WHC) of longissimus muscle were the highest in T-1($3.20kg/0.5inch^2$, 54.32%) and cookingloss was in C-2(22.22%) than the others(p<0.05). However, panel test scores of juiciness, tenderness and flavor of longissimus muscle were the highest for T-1(5.20-5.50 point) between the treatment group. The total catechin and epicatechen in longissimus muscle were higher in treatment group(0.43-046 mg/kg, 0.056-0.065 mg/kg) than control group(0.23-0.25 mg/kg, 0.031-0.032 mg/kg)(p<0.05). The content of total fatty acid in longissimus muscle were oleic acid(48.45-47.56%), palmitic acid(29.67-28.86%), stearic acid(9.92-10.82%), palmitoleic acid and myristic acid(4.68-5.49%, 2.48-3.89%) of range. In conclusion, the effects of feeding dietary mugwort of Hanwoo steer were improved the quality beef with highly panel test scores(juiciness, tenderness, flavor) and physical-chemical characteristics(shear force value, WHC).

Virtualization allows multiple commodity operating systems to share on a single physical machine. Resource allocation among virtual machines is a key to determine virtual machine performance. To satisfy time-sensitive task on a domain, hypervisor needs to observe the resource requirements and allocates proper amount of CPU resources in a timely manner. In this paper, we propose a realtime credit scheduler for latency sensitive application on virtual machines. The key idea is to register a time event in the Xen hypervisor. Experiment result shows that the proposed scheme is superior to Credit scheduler.

Effects of supplemental charcoal powder and vitamin A on physico-chemical properties in 24 Hanwoo steers were investigated. The Hanwoo steers were randomly assigned to one of the three dietary treatments : 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 2% charcoal powder and 0.2% vitamin A) 3) T2 (commercial feed with 2% charcoal powder). Crude fat content of proximate chemical composition in longissimus muscle was increased at control but moisture of control was rather lower than that of treatment groups (p<0.05). The WHC (water holding capacity) in longissimus muscle was tended to increase in control and shear force was higher in T2 (p<0.05). However, effects of diets charcoal power and vitamin A on pH were not found (p>0.05). Tenderness and flavor of sensory evaluation was improved significantly in control with peculiar and savory taste of Hanwoo being more emphasized. But Juiciness were not difference by treatments. When Hanwoo steers were fed with dietary charcoal powder and vitamin A, the palmitoleic acid and linoleic acid contents were higher compared with that of control (p<0.05), but oleic acid was higher in control than others.

쑥 사료를 급여한 거세 한우의 생산성과 냉장 저장 중 육질에 미치는 영향

A total of fifty Hanwoo steers raised from 14 to 29 months were used to investigated the effects of dietary mugwort on the performance and meat quality during refrigerated storage. A feeding trial was tested for 14.7 months and experimental diets included 0 and 2% dried wild mugwort. Total weight gain and average daily gain in this study were significantly higher in mugwort treatment than control treatment. Feed efficiency was improved by mugwort treatment compared with control treatment. Any difference in GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrubic transaminase), and BUN (blood urea nitrogen) was not observed between groups. Carcass weight and longissimus muscle area were higher for mugwort treatment than control. As fattening increased, total cholesterol in blood increased. Total cholesterol in blood tended to be lower in mugwort treatment than control treatment (p<0.05). The heating loss, $L^*$, $a^*$, $b^*$, chroma, and hue unit of all treatments were not affected treatment, but showed a significant decrease in all treatments during refrigerated storage. For fatty acid composition in longissimus muscle, dietary mugwort supplementation increased unsaturated fatty acid than saturated fatty acid (p<0.05). Based on these findings, it is obvious that supplementation of mugwort at 2% level will be useful to decrease cholesterol, increase unsaturated fatty acid, and improve growth performance of Hanwoo steers.

러시아의 대외 군사·안보정책 결정과정 : 대한반도 정책에 미치는 영향 Its Effects on Policy toward Korea

김병기 한국전략문제연구소 1998 전략연구 Vol.5 No.3

When Boris Yeltsin was elected President of the Russian Federation in 1990. the former Soviet republic lacked those crucial political institutions necessary for consolidating his power and authority. These organs-which existed in other republics. which thereby enhanced the political consolidation of former Communist Party members who came into power-constituted the republican Committee on State Security (or the KGB). the Ministry of International Affairs. and even Academy of Sciences and radio/television channels. Lacking the institutional bases for effective rule, Yeltsin on the other hand, inherited Soviet power ministries with whom he had to struggle to "Russianize" it. The Communist Party of the Russian Federation, and the Liberal Democratic Party which inhetrited the balk of the organizational and ideological remanants of the powerful Soviet Communist Party apparatus. moreover, generated major barriers towards institutionalization of Yeltsin's presidency. Such difficult situation, on the whole. helped generate the bloody suppression of the Parliament on October of 1993, the consolidation of the anti-center oriented Siberian Agreement of 1994, and even the Chechen crisis from the same year. Andrei Kozyrev followed a policy of full and complete Westernization in 1992, agreeing on all major issues which NATO and the United States positively thought. including the joining of the military coalition against Irag--a former ally of the Soviet Union. Such policy, however, brought not full economic, political and military integration with the West, but isolation and new ideological division along the shrunken border of the Russian Federation with the Baltic countries, and the CIS. Contrary to expectations, former members of the now defunct Warsaw Pact Organization began to join NATO, while even members of the former Soviet Union begin to seek membership. Kozyrev, all in all, ignored not only Russia's strategic interests vis-a-vis the West, but also, its immediate concerns in the Near Abroad where millions of ethnic Russians resided, who were facing daily economic, social and even political threats to their security. These problems were seriously politicized; the Communists and the Liberal Democrats along with the scattered Russian armed forces began to call for a turn towards "within" and the much ignored "Near Abroad." Between the years 1992 and the beginning of 1996, Kozyrev was forced to follow the lines of the domestic conservatives, thereby weakening the institution of the Presidency, and generating the popular image of a weak-willed administration. At the beginning of 1996 Yeltsin appointed Yevgeny Primakov--then the Director of Counter- Foreign Intelligence Agency--as Foreign Minister. A Middle Eastern expert by training and a long-time bureaucrat in the Propaganda Department of the Central Committee he began to reorient Russian foreign policy away from US/West Europe to the Near Abroad. In the national security concept developed in 1998, for example, the predominant emphasis is placed on domestic dimension, namely, stablized economic transition towards market economy, and parellel social conditions. In the field of external policy, Primakov proved instrumental in preempting a formation of second military coalition against Iraq--with the help of France and China. In fact, Primakov is reportedly supplying Iraq with nuclear technology for energy purposes. Primakov also actively opposed the expansion of NATO, pressuring the Baltic countries not to join the military bloc. Parenthetically, such show of pressure against the West meant that within the Commonwealth of Independent States (CIS) no outside forces can interfere: moreover by exporting missiles to Northern Cyprus, an area controlled by Greece. which has a confrontation with Southern Cyprus. an area controlled by Turkey. Primakov intends to weaken NATO internally. by accelarating tension among the two members. The contraction of the border in the Western frontier. and threat of NATO toward it has forced Russia to seek compensation in the Southern frontier. In the Caucasus. Moscow was successful in forcing Georgia to join the CIS by supporting the Abkhazian seperatists as was also with Azerbaijan whose enemies Armenia and its seperatists in contentious Nargono-Karaback it also supported. Moscow felt threatened by the ethnic-disturbances in the Caucasus and the geopolitical encroachements being made by Turkey. a strong ally of the United States. Primakov is reinforcing Russia's relations with Iran for three reasons: (1) to offset Turkey. China and the US' influence in the Middle East and Central Asia: (2) to deny US rapproachment with Tehran with whom Washington desires closer trade and political relations: and (3) to export, like towards irag. nuclear related technology for energy purposes. In Kosovo. moreover. Primakov has intervened on behalf of the Serbs against the Albanians. whose forces are supported by the Western diplomatic community. These policies have earned Primakov not only the support of the Communists and the Liberal Democrats who form the majority in the Duma, but also, have strengthened Yeltsin's. domestic position through essential conservatization of Russia's foreign policy. It is support for these feats that Yeltsin awarded the highest medal of public service to Primakov as well as personally visiting him at the Foreign Ministry this year. Primakov has also recently engineered the breakthrough in the reestablishment of talks with Tokyo for normalizing its relations. a moved aimed at weakening the US grip on Japan. Moscow knows and appreciates the markedly grown influence of China in both Koreas: it also worries the recent improvement of US-Sino relations. Only by improving its relations with Pyongyang can Moscow redress its imbalnce on the Korean peninsula; but given the five years of freeze in its relationship. Moscow had no means of approaching Pyongyang other than by way of kicking out the South Korean diplomat as a way of showing Pyongyang that it is ready to deal more equally with North Korea. Given the current freeze in North Korean-US. North Korean-Japanese and inter-Korean talks. Seoul must be ready to exercise more independent initiative in its foreign policy.
