In this study, the characteristics of the white charcoal from charcoal kilns made for both charcoal production and thermotherapy and from the traditional charcoal kiln were compared and examined. A charcoal kiln for thermotherapy as a secondary purpose was made to minimize environmental problems such as fine dust and harmful gas generated from sealed charcoal kiln in consideration of comfort and safety. White Charcoal produced from the charcoal kiln for both charcoal production and thermotherapy had higher ash and volatile matter and lower fixed carbon than that from the traditional charcoal kiln. The density of the white charcoal produced from the charcoal kiln for both charcoal production and thermotherapy was slightly higher than that of the traditional one, but the equilibrium moisture content and pH were not significantly different. The calorific value, refinement degree, hardness and anatomical structure were not different between the two. It was concluded that the white charcoal produced from the advanced charcoal kiln for thermotherapy as a secondary purpose meets the quality certification standards of Korea Forest Research Institute.

This study was to investigate the housewives' purchase behaviors on the environment-friendly agricultural products (EFAP) by survey in Daejeon area housewives. 390 questionnaires were used and analysed. Most of the subjects were female (92.6%) distributed evenly in their 40's (55.4%), and graduated from high school (43.6%) or college (36.4%). Subjects' occupation was most housewives (64.1%) and 77.4% of the subjects had monthly family income of 2 million won or more. 76.9% of the subjects had purchased EFAP already. The reason of purchasing EFAP was mainly "good for health" (80.3%), and reason for non-purchasing was "high prices" (28%) or "not so trustworthy" (25.6%). The most purchasing frequency was "once a week" (29%). 46.7% of the subjects spent 20% of their agricultural product cost for EFAP and 38.7% of them spent less than 30,000 won per month for EFAP. On checking of EFAP labeling, the housewives scored 3.59 for the validate date, 3.25 for the place of origin, 2.8 for the quality certification mark by 4-point Likert scale. 65.1% of the subject had intention to increase purchasing of EFAP in future. To promote the consumption of EFAP, the improvement factors were price-cutting (47.9%), trust on producers (18.2%) and quality betterment (17.7%). Accordingly, the consumers prefer EFAP for wellbeing health of families; however, they hesitate to buy due to their high price and the low reliability on producers of EFAP. Thus the producers and the related organization of EFAP should contrive proper countermeasures to increase consumer's satisfaction level on their credibility and price of EFAP.

The objective of this paper is to elicit some policy implications to promote agroforestry in South Korea from the consumers' perspective. We conducted internet survey to 640 urban households about the recognition of forest farming products. Consumers purchased forest farming products for their nutrition, medical function, and safety and regarded them as higher quality than crops cultivated from agricultural land. Consumers preferred forest farming products but revealed no difference in recognition of naturally-grown products. Consumers buying forest products prioritize the quality and medical function among attributes. Among consumers as their income increases, they regard naturally grown products more important than price and freshness. Therefore, to promote agroforestry in South Korea, certification for naturally-grown products to win the consumers' trust and the $6^{th}$ industrialization by combining experience and green tourism program must be considered.

Objectives: Republic of Korea has entered an aged society, recently. As chronic diseases increase, elderly inpatients has been increasing and they have used caregivers for convenience. Accordingly, this study aims to investigate the oral health knowledge and attitude of caregivers on oral health management of elderly inpatients, which would affect the general health and quality of life. Methods: A survey questionnaire was distributed to the caregiver(n=165), at a neurosurgery or orthopedic hospital inpatient ward in Seoul, Gyeonggi-do from April 1 to 14, 2017. We analyzed the data with descriptive statistics analysis, chi-squared analysis and logistic regression analysis by using SPSS 23.0. Results: The response rate to the questionnaire was 92%. Oral health management provided by caregivers to inpatients in the elderly was prevention of oral diseases(92.8%), tooth brushing (89.5%), use of oral care products(68.4%), denture cleaning(90.8%) and oral cleaning(90.8%). Frequency analysis of oral health management in accordance with the educational needs of caregivers was all confirmed statistically significant(p<0.05). In the logistics regression model, oral health knowledge was significantly associated with low oral cleaning(OR=1.58) and oral health attitude was significantly associated with high denture cleaning(OR=1.29) and oral cleaning(OR=1.28) after adjustment for other covariates including gender, age, certification, education level, ward, working years. Conclusions: It is necessary to expand the scope and improve the quality of education that can change the attitudes and behaviors of the caregivers on the oral health management of the elderly on the basis of the current oral health education.
