Lateral Information Propagation Neural Networks (LIPN) is proposed for on-line interpolation. The proposed neural network technique is the real time computation method through the inter-node diffusion. In the network, a node corresponds to a state in the quantized input space. Through several simulation experiments, real time reconstruction of the nonlinear image information is processed.

공공서비스의 지역적 불균등을 분석하는 것은 사회복리지리학에 가장 큰 주제 가운데 하나이다. 이 연구는 1885년~2005년 동안 광주광역시를 포함한 전라남도 지역을 대상으로 연구지역의 객관적인 사회복리 수준의 지역적 변화를 분석하기 위해, 군집 분석기법을 비롯한 다양한 사회복리 수준 측정 방법을 사용하였다. 분석결과 지난 20년 동안 연구지역의 전반적인 사회복리 수준이 향상되었다는 것을 확인할 수 있었다. 하지만 도서지역의 경우 사회복리수준의 발전이 상대적으로 미약한 것으로 나타났다. 따라서 도서지역의 사회복리 수준을 개선하기 위한 정책적 방안이 수립될 필요가 있다.

Purpose: The purpose of this study is to analyze the cost efficiency of food industry in JeollaNamdo. And this study is focused on the correlation between the economic efficiency of food industry and its cost efficiency, based on the analysis of 372 food companies' data in JeollaNamdo in 2012. Methods: DEA cost minimization is the measurement of the cost efficiency of JeollaNamdo food industry in 2012. In this study, the CCR and BBC models have been employed to analyze the decomposing cost efficiency-technical efficiency, allocative efficiency, and scale efficiency respectively. And the Spearman rank correlation and Wilcoxon signed rank test also have been employed to check the correlation and difference between the ranking orders based on the efficiency scores respectively. Results: For the CCR model, mean cost efficiency was found to be 0.084(0.54 for allocative efficiency and 0.19 for technical efficiency). For the BCC model, mean cost efficiency was found to be 0.252(0.453 for allocative efficiency and 0.564 for technical efficiency). Average scale efficiency was found to be 0.38. In analyzing the results, this study argues that the optimal way to improve cost efficiency is by reducing inputs proportionally and changing their combination. Conclusion: The efficiency scores of the two models show high correlation, whereas, the differences between them are also found to be significant. Hence, it should be cautious to select a suitable model when we do the research.

In this study, we determined the ingredient analysis of harvested garlic bulb and soil analysis of four garlic-cultivated regions in Jeju, being one of the major areas of Namdo garlic production. Soil pH and electric conductivity were 7.02 and 1.03 dS/m, respectively. Soil organic matter was 4.31%. The mineral elements (potassium, calcium, magnesium, sodium, iron, manganese, copper and zinc) of Namdo garlic cultivated soil were analyzed by ICP, and calcium was the most highly contained mineral with $14.67cmol_+/kg$ and in the decreasing order of magnesium ($2.25cmol_+/kg$), potassium ($1.51cmol_+/kg$). Soluble solid and total acidity were 7.60 oBrix and 0.49%, respectively. The mineral contents of garlic bulb were in order of potassium (12,728 ppm) > sulfur (7,778 ppm) > phosphorus (4,916 ppm) > magnesium (691 ppm) > calcium (359 ppm). The content of total phenolic, total flavonoid and reducing sugar were 71.14 mg GAE/100 g, 17.64 mg QE/100 g and 26.53 mg GE/g, respectively. Alliin and allicin were 8.78 mg/g and 2.10 mg/g, respectively. The Pearson's correlation coefficients between mineral contents of soil and garlic bulb are analyzed. Macronutrients of soil is correlated with macronutrients of garlic (positive) and micronutrients of garlic (negative) contents.

We have analyzed operating characteristics of hybrid-type superconducting fault current limiter (SFCL) according to the parallel connection of secondary windings with $YBa_{2}Cu_{3}O_{7}$ (YBCO) films. The turn ratio between the primary and secondary windings of each reactor was 63:21. Hybrid-type SFCL using a transformer with parallel reactors could reduce the unbalanced quench caused by differences of the critical current density between YBCO films. We found that hybrid-type SFCL having parallel connection induced simultaneous quench between the superconducting elements. The quench-starting point at this time was almost same. When the applied voltage was 200V, the limiting current in the hybrid-type SFCL with a serial connection was lowered to 34 percent than that in the SFCL with a parallel connection. In the meantime, when the voltage generated in the superconducting elements was the same, the current value in the parallel connection was 60 percent less than in the serial connection. The voltage generated in the primary winding also showed the similar behavior. In conclusion, we found that the fault current was limited more effectively in the SFCL with the serial connection but the power burden of the superconducting elements was reduced in the parallel connection.

This study was conducted to design and manufacture a final prototype of garlic separator and to evaluate its performance. The performance of garlic separation was compared with manual separation. The final prototype for garlic separation consists of bucked-elevator device for automatic feed of garlic, rotating cone typed device, blower, and power transmission device. The optimal condition of outlet clearance was 19 mm and in this clearance, the proportions of fragment garlic separated in the large quality of Namdo garlic and all quality of Uiseong garlic were above 95% and above 85%, respectively. All proportion of damaged garlic was below 5% for all variety and quality. The garlic separation capacities of this developed machine were 310 kg/h for Namdo garlic and 293.6 kg/h for Uiseong garlic in the large quality. Capacities of final prototype compared with human being were $12.9{\sim}19.6$ times for Namdo and $24.2{\sim}31.7$ times Uiseong garlic, respectively.

Recently, there have been active researches regarding endocrine-disrupting chemicals (EDCs). In this study, fifteen small freshwater streams in Cholla-namdo province, South Korea were investigated with respect to the concentration of the endocrine disruptors - Bisphenol A (BPA), styrene monomer (SM), styrene dimer (SD), and styrene trimer (ST) by gas chromatography-mass spectrometry (GC-MS). Measured concentration of the target compounds in the sampled water ranged from
