This study attempted to segment food festival market based on delineated motivation and find factors and find the difference attendants' characteristics among segment market. The study also explored the influence of motivation factors on satisfaction. The results shows that The results are followings : (1) Derived factors of food festival attendance motivation were 'food', 'escape', 'familey togetherness', 'entertainment'. (2) A cluster analysis identified three segments for four motivation factors. Three segments were found to be different according to age, income, the number of company, and information source. (3) Four motivation factors had significant influence on satisfaction. food factor's influence was the highest. and 'family togetherness', 'escape', 'entertainment' are ranked accordingly.

Saseol Sijo which reflects on people's life often showns us relationships between love and economy of those periods' people in Chosun dynasty. Meaning of a word 'housewife' is a woman who supporting and organizing family with her husband. Materialistic problems and economic problems appeared in Saseol Sijo emphasize entertaining and merrymaking rather than struggling to the society enforcing poverty. Therefore, it is often said that Saseol Sijo stimulates overconsumption of goods and money. We can regard sexual discussions appeared in those periods' Saseol Sijo as reflections of desire which are the way of releasing repressed sexual appetite of women or substitutions of satisfying their sexual appetite. Features of housewives appeared in Poong-ryu-bang and Saseol Sijo which are succeeded as productions of merrymaking in Latter half period of Chosun dynasty, can spotlight because of its meanings. It told us not only housewives' roles are started to change but also vivid sexual discussions similar to nowadays things are begun in latter half Period of Chosun dynasty. Main subject pecuniary mediated sexual discussion of housewives appeared in Saseol Sijo teaches a lot of things to twenty first century's contemporary people experiencing collapsed family relationship, pariakapitalismus and wide spread sexual industries.

This study was designed to examine the influence of social-environment factors on high risk alcohol consumption. The study analyzed 229 local areas throughout Korea. Main variables included high risk alcohol consumption and environment factors such as population structure, liquor stores. For exploring the problem drinking, geographically weighted regression(GWR) using the geographic information system(GIS) was utilized to analysis. Major findings are rate of perceived stress, number of restaurants and bars. Especially problem drinking were influenced restaurants and bars, and the form or aim of restaurants and bars had differentiability to the problem drinking. These results have implication about the regulation policy of alcohol availability for prevention of alcohol related problems.

In this research, we estimated the number of hits per song and its sampling error from 11 (areas including Gangnam) based on log data compiling the number of hits collected from offline karaoke players in March 2011. Then, we calculated the monetary equivalent of the sampling error under the current system that distribute royalties from the karaoke players to copyright holders(song writers and arrangers) according to the estimated hits. Because of the small sample size, the estimated number of hits had a very large sampling error. This research proposes a more reasonable sample design to estimate the usage of copyrighted music works for a fair distribution of royalties by reducing sampling error.

Locally optimum detectors are useful for detection of signals with small strength, but it is often difficult to implement the exact form of the locally optimum nonlinearity. In this paper, a suboptimum quantizer detection system in which the locally optimum nonlinearity is replaced by a uniform quantizer and a coder is proposed. The proposed system does not require iteration to obtain the quantizer parameters and is easily implementable.
