Our society is changing into the society of knowledge and information since the advent of 21st century. This may require that schooling need to have a new paradigm. Korea has already entered into the aging society with the help of various population control policies such as birth control from 1960s, and is expecting to go into the so called ultra- aging society. Elementary and middle schools have been facing the rapid decrease in the number of students since the mid-1980s, which high schools are now confronting with. The present study investigates how to effectively utilize extra classrooms at schools. The present study offers eight basic directions that may help establish the utilization planning of extra classrooms. One direction is offering an appropriate space utilization environment, another is to present a plan for having special classrooms. Others are having multi-purpose classrooms, management on the unified rooms for library and audio-visual teaching, securing facilities rooms for the school staff. And others are the planning of the diversion of living space for improving sanitation and the provision of meals, the necessity of the extension or rebuilding of school buildings for other uses according to school development schemes, the utilization planning for community residents to which each school belong.

The objectives of the present study were to investigate whether or not dietary lysine addition could improve N balance of female Japanese Saanen goats at 15 to 32 months of age, weighing 31 to 40 kg, fed on a wheat bran-hay cube diet supplemented with methionine, and whether or not ruminally protected lysine supplementation could give as good an N balance performance as lysine in the presence of ruminally protected methionine when given orally to the goats. It was considered from changes in N balance and N utilization that the first-and second-limiting amino acids in the diet were methionine and lysine respectively, under the present experimental conditions. The ruminally protected lysine in addition to the ruminally protected methionine gave no improvement in N balance and N utilization compared with the ruminally protected methionine alone, suggesting that the ruminally protected lysine used in the present study was not effectively utilized by the goats.

Only 22.7% of total land area is arable land in Korea, it is anticipated that the increased land utilization of present arable land and enlargement of arable land through the reclamation of hillside and tidal land will be of great importance for the support of increased population in the future. Followings are the prediction of increased land utilization ratios, increased arable land through the reclamation of hillside and tidal land, and the increase] in fertilizer demand up to the year of 2000. 1. On the assumption that irrigation facilities, farm mechanization, and cropping systems would be improved remarkably by the year of 2000, the land utilization ratios of paddy land and upland are estimated to be 179% and 193% respectively. 2. Increments of fertilizer demand due to increased land utilization ratios, are estimated to be 2, 290 M/T in 1980, 70, 611 M/T in 1990, and 153, 619 M/T in 2000, when the amounts of fertilizers per unit area are fixed at present lrevels. 3. Increments of fertilizer demand due to the expansion of arable land through the reclamation of 516,330 ha of hillside land and 160,568 ha of tidal land, which are the present estimation of the reclaimable areas, are estimated as 32,960 M/T in 1980, 136,320 M/T in 1990, and 366,861 M/T in 2000. 4. Total increments of fertilizer demand due to the increased land utilization of arable land and the expansion of arable land through the reclamation of hillside and tidal lands in 2000's are estimated as 196,285 M/T for N, 147,351 M/T for $P_2O_5$, and 176,844 M/T for $K_2O$.

To survey the present qualities of the molded and to present the base line of qualities in manufacture, the charcoal collected at 27 makers through the nation were examined. The molded charcoal examined in this paper, which is made by carbonization and molding of sawdusts from wood industries, is widely used to kindle holed-coal-briquette. The holed-coal-briquette is utilized in cooking and heating as primary energy source of ordinary households in this country. The average qualities of molded charcoal was as follows; ash content 13.95$\%$, weight 184.6g, density 0.47, time of kindling holed-coal-briquette 65.4 min., calorie 5,790 kcal/kg. The ten makers produced inferior qualities, that was 37 per cent of the 27 makers examined. The base line of qualities of molded charcoal was defined as follows; ash content below 17$\%$, weight above 175 g, falling strength above 300 mm, calorie above 5,500 kcal/kg.

In inner harbour of Inchon Port, there are two lock gates (50KT, 10KT) which have two gates per lock gate in inner/outer sides except a gate in inner harbour side 7f 10KT. Due to the lack of the fore-mentioned gate, the use of 10KT lock gate Is suspended in every 3 years for regular maintenance. Now an additional gate is under construction in order to improve the efficiency of the 10KT lock gate. This paper will be aimed to evaluate the operational utilization levels of lock gates in present and future. The present operational utilization levels of lock gates are 0.2119 in 10KT lock gate, 0.2051 in 50KT lock gate which were considered the 46.5 closed days every 3 years for 10KT regular maintenance. The levels are estimated to 0.2246(10KT), 0.2539(50KT) in 2006 and 0.2241(10KT), 0.2560(50KT) in 2011. The levels of 50KT lock gate are evaluated to be more rapidly increased up to 24.5% in 2011.
