본 논문에서는 무제약 필기체 숫자 인식에 있어서 향상된 RBF(Radial Basis Function) 신경망을 이용한 새로운 접근 방법을 제시하였다. RBF 신경망은 인식률과 인식 속도를 향상시키기 위해 기저 함수로서 Raised Cosine RBF를 사용하였다. Raised Cosine RBF 신경망 분류기의 성능 평가를 위하여 캐나다 몬트리올 Concordia 대학의 무제약 필기체 숫자 데이터베이스를 사용하였고, 실험 결과 98.05%의 인식률을 보였다. In this paper, we presented a new approach to the recognition of unconstrained handwritten numerals using an improved RBF(Radial Basis Function) Neural Networks. The RBF Neural Networks used Raised Cosine as a basis function to improve discrimination and reduce processing time. The performance of Raised Cosine RBF Neural Networks classifier was evaluated using totally unconstrained handwritten numeral database of Concordia University, Montreal, Canada, and the experimental results showed the recognition rate of 98.05%.

In this paper, a fracture mechanics evaluation system which can be used to assess the leak-before-break (LBB) of nuclear piping is developed. Existing solutions for calculating the fracture mechanics parameters (J-integral and crack opening displacement) required for LBB evaluation were firstly presented. Then a module for calculating J-integral and COD was developed, with an additional module for predicting the critical load based on the crack driving force diagram to finally develop a fracture mechanics evaluation system. To confirm the validity of the proposed evaluation system, finite element (FE) analysis was performed, and the FE J-integral and COD results were compared with prediction results using the J-integral and COD estimations program. Furthermore, the critical load assessment module was verified by comparing the actual pipe test results (Battelle test data) with prediction results using the proposed program.

Agricultural Parity Ratio Its effects upon-Grain supplyAccording to economic theory, favorable or unfavorable agricultural prices usually can induce a marked influedce upon the rate at which new technology is adopted, and , in return, upon the rate of change in agricultural supply. In order to apply this theoretical hypothesis to grain production in Korea, various agricultural parity ratios were made up and used as explanatory variables in both production and yield response functions of grain croup. Other variables such as weather and new variety fo high-yielding rice were also included in this analysis. Both price elasticities of supply and yield were calculated from estimated econometric models. Three kinds of model were employed on oredr to estimate and analyze the different responses to different parity conditions over time, The reuslts show that favorable parity conditions have impacts upon the agricultural supply positively. Elasticities of supply range from 0.15 to 0.35 according to the three models estimated in this study. They show that if a favorable parity ratio is maintained over a longer period, the more elastic is the supply response. The same results were obtained in yield analysis. Therefore, it is argued that favorable agricultural parity ration should be created and maintained in order to improve agricultural productivity and thereby increase total grain production.

全羅南道의 쌀 需給現況과 그 展望

Even though agricultural production increased steadily for more than two decades, Korea(ROK) is still unable to meet her rising domestic demand, and food grain imports have continued to rise throughout the 1960s and 1970s. Consequently, the expenditure of food grain imports in 1981 was about 2.1 billion Dollars, which is more than 42 times greater than it had been in 1965. The rate of self-sufficiency in food grains in 1981 was 43.2 percent and the prospect of self-sufficiency in the near future does not appear to be very good at all. Among food grains, rice dominates Korean agriculture. Over 1.2 million hectares were devoted to the cultivation of rice in 1981. However, Korea only produced about 66.2 percent of domestic demand for rice in 1981, and this situation may get worse due to the rapid increase in demand for rice. Per capita consumption of rice decreased from 136.4kg in 1970 to 131.5kg in 1981, but the consumption ratio of rice to the entire food grains rather went up from 62.2 percent to 67.1 percent in the same period, which exemplifies the relative importance of rice crop in Korean agriculture. Chollar Namdo produces rice most among other provinces in Korea. In the past two decades, about one-fifth of total rice produced in Korea has been attributed to Chollar Namdo annually, where rice production has been increased with an annual growth rate of 5.33 percent. About 58.1 percent of total acreage used for food grain production in Chollar Namdo was devoted to the cultivation of rice in 1981. This includes almost all of the available arable land for rice production, the remainder being very expensive to develop inasmuch as most of it is extremely rugged. An Acreage Response Function for rice production was estimated by employing the Ordinary Least Squares technique. The elasticity of acreage with respect to the expected net profit hectare was shown to be very inelastic, which reinforces the assumption that almost all of the arable land has been already utilized. Yield of rice per hectare in Chollar Namdo increased more than twice in the last two decades, from 2,036kg in 1960 to 4,254kg in 1981. It has been increased with an annual growth rate of 6.59 percent. The principal factors in higher rice yields have been the use of improved seed variety of higher-yields, fertilizers, pesticides, and improved farm management. It is expected that rice yields will increase gradually with new variety of higheryields in the future. Also, the elasticity of yield with respect to the expected net profit per hectare was quite inelastic. Total rice production in Chollar Namdo can be obtained when acreage is multiplied by yield per hectare. By using several different assumptions upon rice yields and acreage in the future, future rice production was projected up to 1986. According to this projection, betweeen one and one-half million metric tons of rice will be produced in 1985. The elasticity of production with respect to the expected net profit per hectare was obtained by adding up the elasticities of acreage and yield. Per capita rice consumption in Chollar Namdo increased in general during the last two decades from 122.1kg to 131.5kg The annual growth rate of per capita rice consumption in the farming sector is higher than that of the non-farming sector. However, since the 1960s, the demography of farming sector has changed greatly, largely as a result of the rapid growth of industrial sector during the period. As off-farm employment opportunities became more available with the expansion of nonagricultural industries, many people left their farms to seek their farms to seek their fortune in the cities. It is expected that the farm population will continue to decrease, albeit slowly. Consequently, rice consumption in the farming sector is expected to decrease, whereas that in the nonfarming sector increases. Overall, the total rice consumption in Chollar Namdo will increase up to about 525,000 metric tons in 1986 and it is expected to be stabilized at that level. By the year of 1986, therefore, it is projected that Chollar Namdo could afford to have an excess supply of, at least, 520,000 metric tons of rice, which accounts for 48 percent of the total production projected in the same year. And the quantity of excess supply is expected to be increasing in the coming years beyond 1986.
