The purpose of this study is to identify which width of the base of support(BOS) is safer and more effective in lifting by comparing muscle activations and body sways when lifting objects under the width variation of the BOS. A total of fifteen healthy adults participated in this study. For the width variation of the BOS, the participants changed the width between their feet into three different types(10cm, 32cm, 45cm) and lifted a 10kg four times in each type after going up on a force plate. In order to measure body sways according to the width variation of the BOS, a motion analysis system was used. In addition, in order to measure the muscle activations of lower extremities, including the erector spinae, gluteus maximus, rectus femoris, and tibialis anterior, an electromyogram(EMG) analysis was employed. In addition, the Borg's scale was drawn by quantifying the subjective discomfort levels felt from each width of the BOS. In conclusion, no statistically significant differences according to the width variation of the BOS were observed(p=.295, .308)(p>.05). However, a statistically significant difference was exhibited between the Borg's scale, which indicates the discomfort levels from lifting performances, and the width variation of the BOS (p=.000*).

Oral folk tale, which are organized stories that have been handed down to each district, includes a lot of mention about local specialties related to food. In folk tales consisting of linguistic signs, food plays a role in expressing not only instinct and desire but also order, exclusion and communication of human beings. Understanding the matters of concern or consciousness that community members of the time have put an emphasis on through food included in folk tales can be useful for better understanding the culture of the time and the food in folk tales can be a symbolic code. In this study, food mentioned in folk tales were classified into six groups, medicine, love, god, livelihood, provision and power focused on both inland and coastal regions that are referred to in most of the sixteen volumes of Korean Oral Folk Tales. In addition, the symbolic meanings of these groups were examined. This study can contribute to establishing the foundation of the globalization of the Korean food by determining the way Korea food can become a world class food. This study aims to reinterpret and combine culture and art with the food of Korea based on six symbolic meanings of food expressed in Korean Oral Folk Tales.

Bitter melon (Momordica charantia L.) is a tropical and subtropical vine of the family Cucurbitaceae, widely grown for edible fruit, which is among the most bitter of all vegetables. Bitter melon contains an array of biologically active plant chemicals including triterpenes, proteins, and steroids. The fruit is useful in gout, rheumatism and subacute cases of the spleen and liver diseases. It is supposed to purify blood and dissipate melancholia. It has also been shown to have hypoglycaemic properties (anti-diabetic) in animal as well as human studies. Raw materials of used in pharmaceuticals, health food, cosmetics, food, perfumery and other industries. However, bitter melon is not popular in Korea. For research, development and commercialization of bitter melon in Korea, we collected 13 varieties of bitter melon from domestic andabroad. We study biological and chemical characteristics of bitter melon. In general frui tsize and weight of Philippines and Japanese varieties was larger than that of Chinese and Korean. We are studying chemical analysis of useful compound (diosgenin and GABA) from bitter melon.
