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.

Whit trade increasingly taking place on the global stale, packaging becomes even more important However, there is only a fine line between the balance of waste created by damaged goods and waste created by over-packaging. A vast quantity of material is used by the packaging industry for the reason of bringing products safely to the customers. In this research I gathered 87 samples of various kinds of confectionery to analyse the actual conditions of the appropriate packaging. As a result, the rate of the needless space excluding actual contents comes to over 60% which clearly says that the most products are over-packaged. Despite assertions from the packaging industry that all packaging is necessary in reducing product waste, the research shows us the fact that it's over-packaged. What needs to be questioned, here, is the level of materials we use in packaging our products, and how we can continue to decrease that amount and recycle what we do use. In the future where materials and resources become more scarce, and therefore more expensive, and the methods of disposal become more costly and accountable, designers and manufacturers constantly need rethink and improve methods of packaging.

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.

Influence of acetic acid on xylitol production from xylose using Candida parapsilosis KFCC 10875 was investigated at the different concentrations of acetic acid. Acetic acid was totally consumed below 1.0 g/l of its concentration, whereas partially consumed above 3.0 g/l and remained in the medium during xylitol fermentation. Cell growth, xylose consumption, and xylitol production decreased when acetic acid concentration was increased. Specific growth rate of cell and specific consumption rate of xylose also decreased with increasing the concentration of acetic acid. However, the xylitol yield from xylose and specific production rate of xylitol were maximum at 1.0 g/l of acetic acid. The inhibitory effect of acetic acid on xylitol fermentation increased when pH was decreased.

Changes in intrumental and sensory Theological parameters of chewing gum during storage were stuided. Texture changes are influenced to the great extent by moisture content of stored chewing gum and D.E. of cornsyrup, meanwhile content of cornsyrup, process condition and storage temperature had a little effect on texture change. Highly significant correlation was observed between logarithmic instrumental texture parameters of deformation, bending and puncture test and logarithmic moisture content. And also good correlations were observed between each sensory and instrumental texture parameters. The optimum texture values were estimated by regression analysis.

The shelf-life of wrapped chewing gum(7 sticks) under the climate condition of Seoul was predicted by using moisture gain equation to reach safe moisture limits of 3.16% (dry basis). The overall water vapor permeability of multilayer packaging material was about 0.00045g water/pack day mmHg. The water activity of chewing gum at any temperature was predictable using Clausius-Clapeyron equation. The most significant loss of shelf-life was occurred between June and July, and most products reached the end of shelf-life at July and August. The product which were made in October and November had the longest shelf-life as seven months.
