This study deals with the problem of enlarging the kinds of courses of academic high schools by installing the ‘core’ school with particularized curriculum such as arts or physical education course tracks as well as academic tracks. For last 60 years Korean general high school have operated two tracks, humanities and social science track, and natural science track. Two traditional tracks did not meet the needs of students and society. Survey were administered to secondary school students and teachers, asking about the curricular needs of new tracks. Based on the results of questionnaires the simulation of allocating students and teachers, and installing facilities according to the curricular tracks was finished. About 30% of middle school graduates want to go to core high schools with particular track rather than traditional tracks.

This experiment was carried out to investigated the effects of levels of mineral nitrogen under various cutting systems on the nutritive value and nutrient yields of orchardgrass (Dactylis glomerata L.) during harvested years in 1993-1995. The contents of crude protein (CP), total digestible nutrients (TDN), relative feed value (RFV) and annual nutrient yields in relatively wet year (1993) were significantly higher than those in the other harvested years, but the tendency of contents of acid detergent fiber (ADF) and neutral detergent fiber (NDF) were against. The contents of CP, TDN, RFV of all cutting frequencies were highest at the last cut, but lowest at the 2nd cut. The annual nutrient yields were highest at the 1 st cut in 3 cuttings, and at the 2nd cut in 4 and 5 cuttings, respectively. Significantly higher contents of CP in all cutting frequencies appeared in according to increase the levels of mineral nitrogen, but the contents of ADF were lower with nitrogen fertilization of 60 kg ha^(-1) cut^(-1) in 4 and 5 cuttings than those in non-fertilized plots. Higher efficiencies of dry matter production (kg DMY kg^(-1) N), crude protein production (kg CPY kg^(-1) N) and total digestible nutrients production (kg TDNY kg^(-1) N) in response to mineral nitrogen fertilization were recorded as 12.9, 1.4 and 7.6 kg at level of 360 kg ha^(-1) in 3 cuttings, 27.3. 2.7 and 16.0 kg at level of 120 kg ha^(-1) in 4 cuttings, 20.5, 2.0 and 12.7 kg at level of 360 k, ha^(-1) in 5 cuttings, respectively. In all treatments, negative correlation between CP and ADF or NDF appeared (P<0.001). Positive correlations were recorded between CP and TDN or RFV. and among TDN and nutrient yields (P<0.01).

The aim of this experiment was to investigate the effects of applying times and dilution rates of cattle slurry on dry matter yields of orchard grass. Cattle slurry was applied at the rates of average mineral nitrogen fertilizer equivalent to 150 ㎏/ha/year in 3 cutting frequency. Significantly higher dry matter yields than that of no fertilization (3.04 ton DM/㏊) were recorded in the application of diluted cattle slurry (5.59∼6.37 ton DM/㏊) (p<0.05). Especially, this tendency was shown with higher annual dry matter yields at the partitioned dressing times, such as at the applications for 1st growth, 1st and 3rd growth, respectively. The yields of annual dry matter both at fertilizing with phosphorus and potassium, and phosphorus, potassium and nitrogen were higher than no fertilization as 5.40 tons and 8.60 tons per ㏊, respectively. However, with application of diluted cattle slurry, dry matter yield per year (5.92 ton DM/㏊) was higher than those of fertilizing with phosphorus and potassium. The efficiencies of dry matter production with mineral and cattle slurry nitrogen application (㎏ DM/㎏ N) were 21.3 and 14.7∼18.3 ㎏ DM/㎏ N, respectively. Especially, these tendencies were higher in diluted application plots than in no-diluted application plots of cattle slurry.

안익수,노환주,김길준 聖潔大學校 情報産業技術硏究所 1997 情報産業技術論叢 Vol.2 No.-

Statecharts is usually used as the specification model for dynamic model and reactive system, Statecharts is a superior computation model, but aspect of data is expressed by global variables and side effects to them, so the readability is lower when we describe larger systems in Statecharts. Moreover state structure in Statecharts is less relevancy to structure of object model. In this paper we propose the specification model OMT++. In OMT++, dynamic model is described with the structure of object model, which have more relevancy to structure of object model and more locality caused by making each object have state transition diagram and data. We show the prosperity of OMT++ through examples, and compare with Statecharts, and give operational semantics of OMT++.

This study was carried out to find the effects of the mixtures of earthworm cast and coffee lees as a vegetable plant growth medium on the growth of hale seedlings. The mixed ratios of earthworm cast and coffee lees were 100:0, 75:25, 50:50 25: 75 and 0:100%. The results of the study are as follows: 1. The hydrogen ion concentration(pH) was recorded 7.54 in nursery soil with 100% of earthworm cast treatment, but the lower mixed ratios of earthworm cast in nursery soil were, the more it fell down. Thus, pH in 100% of coffee lees treatment and commercial plant growth medium as control treatment was showed 5.68 and 5.80, respectively. 2. The nursery sorb with 100% of earthworm cast was generally higher than treatment of the others in shoot dry weight per plant. The shoot dry weight per plant was also high in the control treatment except 3rd week, but there was no significant between the control treatment and the treatment including 75% of earthworm cast and of 25% of coffee lees. 3. As growth stages were developed, the plant iength(cm), number of leaves and diameter of stem of kale seedling were increased in all treatments. Especially, it was clear in 100% of earthworm cast treatment. In the meanwhile, the plant Iength(cm), number of leaves and the diameter of stem in the control treatment were higher than those of in treaments consisting both of 75:25 and 50:50(%) of mixing ratios with earthworm cast to coffee lees in the early growth, but in the latter growth in the mixture of 75% of earthworm cast and of 25% of coffee lees was showed a similar tendency to the control treatment.

본 실험에서는 우분과 볏짚의 혼합수준을 달리하여 지렁이 먹이로 이용하였을 때, 지렁이 생육과 증식에 미치는 영향과 분립의 생산량 및 화학적 조성을 조사하여 우분의 효율적인 Vermicomposting의 기초자료로 이용하고자 실시하였다. 그 결과를 요약하면 다음과 같다. 먹이의 C/N율은 20.4∼28.2로 볏짚 수준이 증가함에 따라 C/N율도 높아졌으며 실험기간 동안 지렁이의 생존율은 98.4∼99.2%로 나타났다. 산자수는 볏짚을 30과 40% 혼합한 구에서 각각 868와 906 마리로 우분 100%구의 769 마리보다는 유의하게 높게 나타났다 (P<0.05). 산자중은 8∼11.8g으로 볏짚 혼합 수준이 높을수록 유의하게 높아져 볏짚 40% 혼합구가 가장 높았다 (P<0.05). 분립생산은 볏짚 혼합 수준이 높을수록 낮게 나타났으며 소화량은 이와는 반대로 볏짚 혼합 수준이 높을수록 유의있게 높게 나타났다. This study was conducted to develop efficient vermicomposting using of different mixture ratio of the rice straw and cow manure by feeding these to earthworms and then by studying the growth and reproductive efficiency of earthworms, and the chemical composition of worm cast and its production. The results are summarized as follows. C/N ratio of feed was 20.4∼28.2 and it increased according to the higher proportion of rice straw and survival of earthworm was 98.4∼99.2%. Number of young worms were significantly higher in 30 and 40% addition of rice straw (number of 868 and 906) than number of 769 of real cow manure treatment (P<0.05). Fresh weight of young worms was 8∼11.8g and it was significantly higher in 40% addition of rice straw than other treatments (P<0.05). The cast production of earthworm was in the tendency of becoming higher according to higher ratio of rice straw but digested matter were significantly higher in 10∼40% addition of rice straw than real cow manure treatment (P<0.05).
