        The fruit of Kochia scoparia Scharder is traditionally used as a medicinal ingredient to treat allergic skin diseases and inflammatory diseases in China, Japan and Korea. Recently, several studies reported that K. scoparia had potential for the cytotoxicity of human cancer cells. To investigate the anti-cancer effect of K. scoparia on oral cancer and to determine the specific type of cell death induced by MEKS treatment. We investigated the anti-cancer effects of K. scoparia, methanol extract (MEKS) in HSC4 human oral cancer cells. We examined the effects of MEKS on the proliferation rate, cell cycle arrest, 7-AAD-ANNEXIN V double stain, reactive oxygen species (ROS) generation and activation of apoptosis and necroptosis-associated proteins in HSC4 cells. MTT assay results demonstrated that MEKS decreased the proliferation rates of HSC4 cells in a dose-dependent manner with an IC50 value of 45.3 μg/ml. MEKS at 50 μg/ml significantly increased the sub-G1 DNA contents of HSC4 cells to 84.8%, versus untreated cells. However, the activation of apoptosis-associated proteins such as cleaved caspase 3, cleaved caspase 8, cleaved caspase 9 and cleaved Poly (ADP-ribose) polymerase (PARP) did not detect. The level of Bax protein markedly increased in MEKS-treated HSC4 cells. In addition, the cell viability of the DPQ pre-treated HSC4 cells with MEKS treatment was significantly greater than that of MEKS treated-cells. These results suggest that MEKS inhibits cell proliferation and induces necroptosis in oral cancer cells and that MEKS may have potential chemotherapeutic value for the treatment of human oral cancer.

        The elderly population in Korea is growing rapidly and their nutritional status is not acceptable. Data were collected from the self-administered questionnaire of 495 free living elderly, over 65years old, in Korea to asses the intake and consumption pattern of milk and dairy products. The questionnaire contains demographics, health related characteristics, and perception on milk, and consumption behaviors of milk and dairy products. Most of the elderly subjects understood that milk is good foods in terms of nutritive value and health. And 67% of the subjects satisfied with the sanitation status of milk on the markets. The kind of milk that majority of the subjects consumed was whole milk, and only 5.1% of them consumed low fat milk. Less than 20% of the subjects consumed milk everyday, living alone group consumed milk less frequently than living with others. It was found that the majority of the elderly subjects did not meet current recommendation for milk. Liquid and curd type yogurt were the major dairy products used among elderly, and the reasons were good taste and digestion. They believed that these kinds of dairy products help constipation and digestion problems. The price of milk was ranked for the first factor needed to be considered for milk and dairy products consumption in elderly korean.

        The purpose of this study is to provide basic materials for food service consumption culture by proving the problem with food service purchase and its improvements. For this purpose, it was attempted to grasp university students' food service purchase behavior and level of satisfaction with it and to investigate the factors influencing their level of satisfaction with food service purchase. The questionnaire research was conducted for university students living in Seoul and Chungcheong provinces. 453 questionnaires obtained from them were used for final analysis. As a results, the following finding were obtained: 1. In case of university students, their level of consumer satisfaction with food service purchase was shown to be the score of 37.99(63.06/on the basis of 100 points). They showed the highest level of satisfaction with quality, followed by facility and atmosphere, service, price and the like. 2. The factor having the greatest influence on university students' level of satisfaction with food service purchase was shown to be gender(female), followed by food service place(Korean food restaurant, Chinese food restaurant, Western food restaurant, flour-based meals restaurant), consumer attitude, average monthly food service cost.
