  • Although various publicly reserved funds have recently come to the fore of academic and policy-making attention in Korea, researchers rarely take up the issue of the reserve fund retained from annual profits by the central bank (i.e., the Bank of Korea). Starting with the general public choice premise that bureaucrats seek to maximize their discretionary budget, this paper first provides a theoretical reasoning why central bank's bureaucrats would prefer retaining annual profits to turning them to the Treasury. The major tenet to be emphasized is that retained profits as a reserve fund can give the central bankers discretionary power in their disposition. In particular, we focus on the close relationship between the reserve fund and the discount windows. The latter, as a monetary instrument, has traditionally been demonstrated to cause secrecy, arbitrariness, and other bureaucratic amenities in the previous literature. Subsequently, this paper, based on 61 countries data, empirically verifies that the central bank's reserve fund is at least partially used to additionally increase the discount windows. Since an excessive use of discount windows results in inflationary bias, we conclude the paper with some policy suggestions to have such bureaucratic power of discretion in check. This paper, if in its experimental nature yet, is expected to shed a critical implication for establishing the meaningful independence of the central bank to a host of countries.

  • Based on the guiding ideology of "Close-to-nature forestry", the soil chemical properties of Korean pine (Pinus koraiensis) plantation forest which was early done by canopy gap control were analyzed of Liangshui nature reserve in northeastern China. The results indicated that the nurture of forestry crevice diaphanous tended to improve the soil nutrient contents and significant differences of soil nutrients existed among different levels of soil for the same forest type of Korean pine. At 0< $H{\leq}20$ cm layer, the content of available nitrogen, available phosphorus, available potassium, total nitrogen and total phosphorus in artificial pure Korean pine forest are 640.28 $mg{\cdot}kg^{-1}$, 7.54 $mg{\cdot}kg^{-1}$, 275.91 $mg{\cdot}kg^{-1}$, 1.114% and 0.075%, they all higher than the other kinds of forests and for average 1.1 times, 1.4 times, 1.3 times, 1.6 times and 1.2 times. From the layer of $0<H{\leq}20$ cm to 20 cm < $H{\leq}40$ cm, soil nutrient indicators showed various degrees of decreasing in which organic matter had the greatest decline, decreasing by 170.64% while PH had the lowest decline, decreasing by 4.66%.

  • Study of population density and biomass of soil microarthropods in soil, herbaceous leaf litter and wood leaf litter was conducted at 4 sites with different flora in Mt. Jumbong, a nature reserve area, in Korea from Aug. 1994 to May 1996. Total 47, 849 individuals of soil microarthropods in soil were collected and identified into 6 different classes, and 16 orders. The composition, densities, and dominant group of soil microarthropods were different among 4 sampling sites. Collembola was the most abundant group with 50.7% at South-facing slope and 50.6% at the North-facing slope. But Acari was the most abundant group with 49.8% at Altitude 900m site and 47.7% at Altitude 1100m site. Two group ranged 87-95% of total individuals. A/C ratio was less than 1.0 at 4 sampling sites during the all sampling seasons. As a result of biomass evaluation, rato of Acari was decreased but ratio of Diplopoda, coleoptera, Araneae, Diptera and Chilopoda was increased. About 70% of total orders and densities were found in less than 5cm soil depth. The composition, densities, and dominant group of soil microarthropods were different among soil, herbaceous litter and wood litter. Collembola was the most abundant group in herbaceous and wood litter. A/C ratio was less than 1.0 in litter during the sampling seasons. As a result of biomass evaluation in litter, ration of Araneae and Collembola was very high, but ratio of Acari was low.

  • Purpose of the electric power system planning and operation is to supply the electric energy to customers continuously and economically. With the mutual exclusive laws of nature between reliability and economic, finding the meeting point is very important but not easy. Commonly the probabilistic reliability indices of the electric power systems are represented with negatively. And the effectiveness of FACTS on the probabilistic reliability could not be reflected with common methods. In this paper, a method to evaluate the probabilistic arrival power at each load point is presented. With this new proposed method, probabilistic reserve margin at load points can be calculated and which can be used with positive reliability index also. Using the P-V analysis, the voltage stability is considered in reliability evaluation. It is expected that the proposed method will be useful expecially in reliability evaluation of electric power system which has voltage restriction.

  • Asiatic black Bear(Ursus thibetanus ussuricus) cubs aged one or two were introduced from Russia(Primosky krai) and North Korea for reinforcement of the bear population and they were released to grow wild in Jirisan National Park. We did research on the characteristics of the denning sites of the Asiatic black cubs, which were released before, from Oct. 2004 to Apr. 2006, and the results were as follows: The released bears hibernated in three types of dens,; tree hollows, rock hollows or ground nests. The hibernating sites were dominated by a community of oak trees and its location was at an average of $923{\pm}221m$ height above the sea level ; the average slope incline was $25.9{\pm}7.9^{\circ}$, and the average denning duration was $98{\pm}9$ days. It was analyzed that the cubs' denning site was $2.8{\pm}2.8km$, on an average, far from the release point; $2.0{\pm}0.9km$ far from villages; $1.9{\pm}1.7km$ far from park inspection trails, and $1.9{\pm}1.0km$ on the average far from a driveway. It is assumed that environmental attributes of the denning sites were closely correlated to those of the release points.

  • These studies are carried out to improve silk availability for anticrease by useing methacrylate monomer polymerization method with in silk fiber. For this purpose, degree of anticrease, stiffness and shrinkage of various silk fabrics, included finish or not, after repeat of washings and polyster fabric was compared as standard. The adopted samples are ; 1. Polyester, Georgette, Woven density…90cm-85g/m 2. Silk, Twill, Degumed, Light, Woven density…90cm-90g/m 3. Silk, Twill, Degumed, Heavy, Woven density…90cm-200g/m 4. Silk, Stain, Degumed, Light, Woven density…90cm-90g/m The reached results are as followings. 1. The results of improving on anticrease by the finished method were about ten per cent increase against their original samples. 2. The light density silks showed satisfactory improve for anticrease, but the heavy one remained as rather poor condition. 3. The results for degree of textile stiffness were investigated to make sure reserve their textile feeling and observed to be good condition upon the finish work. 4. Textile shrinkage after the repeat of soap wash was investigated on indivisual test sample and silk fabrics showed more shrinkage than polyester which it seemed to be tentering shrinkage druning their general finishing processes. 5. The investigation showed that anticrease, stiffness and shrinkage of the sample textile were more or less deteriorated regardless silk or polyester by the repeat of washings. These matters are considered that such results were obtained because of the fiber fatigue nature. 6. The report reached that silk textiles should be used by dry cleaning methed after finish of any resin finish to reserve their improved anticrease nature.

  • The Hmong people are one of the largest ethnic groups in Vietnam. They traditionally practice shifting cultivation for their daily subsistence. This group has a traditional governance system as well as strong clan and kinship relationships that occupy an important role in maintaining Hmong culture and livelihoods. The state's approval of the legitimate and statutory law for the Nature Reserve largely excluded local rights of access to and the use of natural resources. This study focusses on Hmong responses to the state interventions of the establishment of the Nature Reserve as well as forest land allocation. Based on Scott's contribution of Moral Economy (1976), the authors argue that local responses function as a 'risk-averter' against state intervention. Meanwhile, the intra and inter-ethnic relationships based on the 'subsistence ethic' help locals successfully mitigate state intervention. These findings help the state rethink their interventions, which have been constructed with very little respect for local differences or the desires of ethnic peoples. Furthermore, the main findings, which reveal that not only the intra-ethnic relationship but also the inter-ethnic relationship among ethnic minorities can play an important role in maintaining the Moral Economy, are expected to deepen the previous understanding on the Moral Economy, which has previously constrained its scope to the intra-ethnic relationship.
