With the development of national economy and increase of income, consumers’ demand for quality and safe agricultural products have increased and perception on environmental-friendly Farming products has been sharply changing. In other words, consumers increasingly show the tendency to prefer environmental-friendly farming products for considering health and environment protection, despite higher price. The environmental-friendly farming products in Jeonnam Province is still at its early stage, accounting for 1% or so of the total products. Considerable part of environment-friendly farming products, nevertheless, difficult problem to find consumers, thus sold at relatively high prices. To the questionnaire asking their most severe difficulty is about 30.5% for sale. This suggests that strategies for consumption expansion of environment-friendly farming products, including of consumers’ confidence, publicity of consumers, should be established to increase the income of environmental-friendly farmers in Jeonnam Province.
대학수학에서의 Fibonacci 수열과 Pell 수열 : A way to enhance the students' interest in Mathematics
김병무 忠州大學校 2004 한국교통대학교 논문집 Vol.39 No.2
In this paper, we introduce the ways to solve the general term of the Fibonacci sequence(FS) and Pell sequence(PS) by using generating function and another methods, and show that the PS has many interesting properties, some of which are analogous to the properties of the FS. In addition, we point out the close connection between the PS and Pell's equation and show that each pair of consecutive terms of the PS generates a primitive Pythagorian triple of a special type. Furthermore, we discuss some properties of the PS that involve ratios and sums. We introduced all these properties and implications of the FS and PS, because we think the FS and PS are very helpful topics for the development of the students' interest in Mathematics and for their appreciation of the elegant world of Mathematics.

This study was made on persons applying for treatment at Korea veterans Hospital Dental Clinic at Seoul, Pusan. 1,758 dental patients were screened from January 1985 to October 1985. The presence or abscence, of tori, largely detected by visual examination were recorded for each patents and the following results were obtained. 1. The prevalence of tori showed that plate and mandibular tori occurred in 25.09%, 10.13%, of each total group. The ratio of tori in palate and mandible was about 2.5:1 and coexisting tori of the palate and mandible occured in 1.31%, of total group 2. palatine tori occured more frequently in female(27.47%) than in male(23.31%) 3. After the 2nd decade of life group, palatine tori revealed significant difference in percentage of occurrence (the 1st decade 11.38%, the 2nd decade 26.4%), with subsequent decade showing no significant difference 4. Slight type palatine tori(73.92%) collectively occurred most frequently compared to moderate(20.86%) and marked(55.22%) type. 5. Mandibular tori occured more frequently in male(11.60%) than in female(8.13%) 6. After the 3rd decade of life group, mandibular tori revealed significant difference in percentage of occurrence(the 2nd decade 4.15%, the 3rd decade 12.6%), with subsequent decade showing no significant difference. 7. Simple bilateral mandibular tori(6.43%) occurred most frequently, and bilateral mandibular tori(87%) collectively occurred more frequently than unilateral tori(13%) 8. Mandibular tori including canine and premolar teeth area(42.93%) collectively occurred most frequently compared to premolar teeth area(32.07%) and canine tooth area(13.04).
