In Korea, confectionery refers to biscuits, snacks, chocolate, candy and gum. The first sweet in Korea is the Yumilkwa (oil-and-honey pastry) in the Goryeo Dynasty which was mentioned in history book, and is seen to be popular in medieval Korea. Korea's confectionery industry began in 1945 with the aid of the U.S. forces, Haitai Confectionery company produced sweets. The first confectionery product is 'Yeon yang gang'. In the 1970s and 1980s, the confectionery industry developed along with economic growth in Korea, and many of the products released at this time are still loved. Now the domestic market is saturated, sales of domestic confectionery companies are decreasing due to low-priced offers made by importers. It is necessary to develop products with high quality and brand power that can lead the market, and I think it is necessary to target the undeveloped market like the Halal market.

It has been studied that the measurement of odor component emission at confectionery manufacture. The objects of this study were to investigate reduction of offensive odor. The survey effects of odorous materials are presented as follows. The countermeasure of operating process is to minimize sludge sediment in each unit facility. Especially, in summer, we have to clean the sludge frequently, because anaerobic decomposing is likely to occur easily. The sludge or scum from sedimentation tank pond, and floating tank should be treated quickly. We should avoid overloading operation. In the case of overloading, dissolved oxygen should be increased, the quality of wastewater input should be decreased. When dried cakes from condense tank or floating tank are left in treatment plant, we should cover, to prevent diffusion of smell with masking materials. The seasonal condition of operating should be fixed and the kind of coagulants should be changed because the wastewater in each season have different loading rates and organic materials. Odorous materials are very sensitive to the seasonal temperature variation. Especially, when the amount of rainfall is small and the high temperature of maintenance in long periods, air diffusion rate is large, so odorous materials can make great effect on surroundings comparision with other periods. To reduce odorous gas, as short term method, we had better take ceramic addition method. Especially, in summer we should take ceramic addition method. Also, as long term method, the size of wastewater treatment facility is the most important in the normal operating of wastewater treatment facility. But wastewater treatment facilities in this factory are too old, treatment process is old fashion, and the size is too small. So, large wastewater quantity to treat in summer. As results, the expansion of wastewater treatment facility and the process of improvement are required. Restriction level of odor was exceed. As it is overloaded in summer, the basis cause of odor is that the size of wastewater treatment facility is small. The prediction of air quality equilibrium density variation show that the odorous materials from working place are Amine materials whose smell strength is about 2.5(a little strong degree). We can suppose that in summer is sensitive to temperature variation, smell strength is larger as to reduce the origin of odor. We must expand wastewater treatment facility and improve the process A.S.A.P.

Mungyung area has contributed to korean industrial development with its abundant natural resources. However, the change of industrial structure caused the decrease of the number of mines in Mungyung and it resulted in the economic depression in that area. Recently. the economic growth of Mungyung is attempted by developing the distribution center of agricultural products and the resort complex using beautiful natural environment such as the film setting of 'Taejo Wang - gun' and hot spring in good quality. In this article I survey the foreigners aware of the principle products of this district and their intention of purchasing the products using local speciality. I also make confectionery experiments on the basis of the survey and develop various confectionery using principle products of Mungyung.

The changes in sensory and mechanical texture of chewing gum during storage at various relative humidity were studied to define the quality index for the prediction of shelf-life. The initial moisture content of chewing gum was 2.57% (dry basis). The BET monolayer value at $a_{w}$ 0.19 was calculated to be 1.57% (dry basis). The sensory scores of chewing gum were closely correlated with moisture content and instrumental texture parameters with 0.1% significant level. Therefore the quality of stored chewing gum was directly related with moisture content above BET monolayer. The products became organoleptically acceptable in the range of moisture content $2.17{\sim}3.16%(dry basis)$. This range of moisture content ie equivalent to the ranges of instrumental parameter, fracture force$0.8{\sim}1.8{\times}10^{7}$, fracture modulus $1.1{\sim}2.4{\times}10^{8}$, puncture force $0.5{\sim}1.1{\times}10^{7}[dyne/cm^{2}]$ and brittleness $0.7{\sim}1.4{\times}10^{8}[dyne/cm^{3}]$, respectively.

Purpose: This study was designed to explore the association of diet with menopausal symptoms in Korean women, Method: For this cross-sectional survey, 276 women aged between 45-55 years visiting two branches of K-university hospital located in Seoul and Ansan of Kyunggi province were recruited from April to July, 2002. A menopause-specific quality-of-life questionnaire and a food frequency questionnaire were used to measure menopause-related symptoms and the intake of 28 types of foods. Result: No differences were found in the levels of bothersome total menopausal symptoms, physical symptoms, psychosocial symptoms, and sexual symptoms according to the intake of each food. Only higher intake of fishes, seaweeds, and vegetable oils were inversely associated with bothersome levels of vasomotor symptoms. Women with higher intake of yellow-green vegetables and lower intake of coffee, confectionery, and processed foods reported lower hot flush rate. Conclusion: The results suggest that higher intake of yellow-green vegetables and lower intake of coffee, confectionery and processed foods may relieve hot flushes. Further study needs to be pursued to study the relationship with nutrients of these foods and hot flushes.
