Nutrition is important in the management of diabetes mellitus, however, there are few little education materials specifically designed for older adults. The objective of this study was to develop nutrition education materials for prevention and management of diabetes moll for older adults. Materials developed were a booklet and four leaflets. The contents of materials were based on lesson plans. After several revisions of the draft of materials, illustrations and icons appropriate to the contents were designed using illustrator 9.0 and Photoshop 6.0. The booklet was composed of five chapters and 40 pages. The first chapter began with an introduction about diabetes and diabetes management by diet, exercise and medication. The second chapter dealt with ideal body weight, calculation of adequate caloric intake and food exchange list. The third chapter provided information for meal planning and sample menus. The fourth chapter focused on practical tips on nutritional care of diabetes, by providing tips on reducing sugars, fat and salt, and suggestions on eating for special occasions. The fifth chapter dealt with information in case of low blood sugars, exercise and foot care. The topics of the four leaflets were “Diabetes, what is it and care”, “Food exchange list and meal planning”, “Healthy eating for diabetes”, “Special care for diabetes low blood sugars, exercise and foot care” Each leaflet was composed of six sections and was printed in large paper (B4 size) for older adults. The draft of educational materials were re-viewed by four nutrition professionals and finally pilot-tested with ten adults aged 50 and older. The characteristics of the developed materials are as follows, i) messages are delivered using simple, specific information, ⅱ) messages focused on practical applicable tips, ⅲ) various pictures, illustrations and artwork were created and inserted to enhance understanding and interest, ⅳ) sections including risk factor assessment, calculation of ideal body weight and meal planning were designed to induce the user's participation, ⅴ) sample menus and food pictures were inserted in the booklet, vi) characteristics of older adults and transformed characteristics are diversely used to help the user feel familiarity. These materials are self-explanatory and can be used by older adults. These materials also can be used widely in nutrition education at public health centers or senior centers.

Chitin is a natural biopolymer that, with its derivative chitosan, has been represented as a biomaterial with considerable potential in wide ranging medical applications. But there are some limitations in using chitosan as attained, for instance, the problem of water solubility$^1$. In order to use chitosan in various applications (e.g. drug carrier), chemical modifications are often necessary$^2$. (omitted)

We know that humans are able to live comfortably when there is a balance between the living environment that surrounds us and us. Clothing, one of the necessities of life, serves a dual purpose of functioning as protection for the body as well as providing visual satisfaction, and so is the most effective bonding mechanism. A different type of comfort that has been provided through industrialization and advancements in technology has resulted in pollution problems in the environment, and it has reached a point of seriously thinking about its effects. The biggest problems in environmental pollution are air pollution and waste disposal, and something that cannot be ignored is that environmental hormones and harmful heavy metals have been discovered in the synthetic dyes used in the clothing product, and not only are they harmful to the body, but they also have adverse effects on skin allergies such as atopic dermatitis. Its effects on clothing, especially underwear and baby products, can become a serious issue. The use of natural vegetable dye can be considered the basis for the traditional Korean dyeing process, however not all natural dyeing process can be thought of as traditional Korean dyeing. This is because natural dyeing used to be the most common method of dyeing before synthetic dyes came along and became the dye of choice for most clothing. Natural dyes are beneficial to the body, and the nature colors, achieved from the natural materials, relieve eye strains as well as have a healing effect for people who are suffering from psychological instability such as stress. However, the use of mordant in order to increase the fastness and get better color effects can lead to even more damage to the environment, and it cannot be a dyeing method that is good for the body. Traditional natural dyeing is different from regular natural dyeing because it uses colors that the Korean people can identify with and applies specific methods in order to achieve those colors. Even though experimental study with dyestuff and practical use of the dyeing methods for traditional Korean dyeing has been started(Soh, H., 1983) and has been ongoing, it is still not easy for regular people to use the method on their own. At the present time, natural dye materials are getting made and sold more than ever, but there is a lot of confusion among consumers regarding the difference between traditional Korean dyeing and natural dyeing, as companies are using the two terms interchangeably to market their natural dye products. So getting a better understanding of the characteristics of traditional Korean dyeing and traditional colors should be considered first priority at this time. The purpose of this thesis is to study the traditional Korean view of color, which developed the culture of traditional dyeing in Korea, and the characteristics of traditional Korean dyeing, a method that pursued achieving Korea's color through natural dyeing.

Purpose: The study aims to evaluate satisfaction of toothpaste adding natural materials extracted from Zanthoxylum schinifolium and various herbs (Pine, Lemongrass, Spearmint). Methods: We performed the first survey to collect basic data for the development of natural herbal toothpaste. Participants were the general public in Jeonju and Iksan of Jeollabuk-do, and a total of 273 questionnaires were analyzed for the study. By adding anthoxylum schinifolium and herbal extracts (Pine, Lemongrass, Spearmint) to the toothpaste, four kinds of natural herbal toothpaste prototypes were manufactured. The second survey was conducted to assess the satisfaction one week after using the natural herbal toothpaste prototypes. Results: Satisfaction with current toothpaste was 3.52. The most important criterion of toothpaste was the prevention of tooth caries. 55.3% participants obtained toothpaste information through advertising. The survey indicated the most worrisome ingredient of toothpaste was surfactant, showing 55.3%. The overall satisfaction of natural herbal toothpaste was 3.99; among the four natural herbal toothpaste, toothpaste 2 (Zanthoxylum schinifolium, Lemongrass) showed the highest satisfaction as 3.99; and toothpaste 3 (Zanthoxylum schinifolium, Spearmint) showed the lowest satisfaction as 3.56. Conclusion: Four kinds of natural herbal toothpaste showed higher satisfaction as 3.99. In particular, the toothpaste adding Zanthoxylum schinifolium and Lemongrass extracts.

To examine the magnetic shielding effect for carbon-based materials at extremely low frequencies (60 Hz), two types of carbon black (Super-P and Denka Black) and a natural graphite (HC-198) were mixed into organic binder at 10 wt.% to produce a coating solution, and a powder coating with varying thickness was applied on an aluminum disk measuring 88 mm in radius. A device was developed to measure the sheielding effect at extremely low frequencies. A closed circuit was achieved by connecting a transformer and a resistor. The applied voltage was fixed at 65 V, and the magnetic field was measured to being the range of 4.95~5.10 mG. Depending on the thickness of the coating layer, the magnetic field showed a decreasing trend. The maximum decrease in the magnetic field of 38.3% was measured when natural graphite was coated with specimens averaging $455{\mu}m$. This study confirmed that carbon-based materials enable magnetic shielding at extremely low frequencies, and that the magnetic shielding effect can be enhanced by varying the coating thickness.
