Korean is free of omission of sentence elements and modifying scope, so managing it on morphological analyzer is better than parser. In this paper, we propose functional expansion methods of the morphological analyzer to ease the burden of parsing. This method is a longest phrase matching method. When the series of several morpheme have one syntax category by processing of Unknown-words, Compound verbs, Compound nouns, Numbers and Symbols, our method combines them into a syntactic unit. And then, it is to treat by giving them a semantic features as syntax unit. The proposed morphological analysis method removes unnecessary morphological ambiguities and deceases results of morphological analysis, so improves accuracy of tagger and parser. By empirical results, we found that our method deceases 73.4% of Parsing tree and 52.4% of parsing time on average.

To verify the suitability of microwave digestion method for analyzing macro nutrients and metals. K, Ca, Mg, Cu, Zn, and Mn contents in plant and composts were investigated comparing with conventional wet digestion method. Because it takes short time to digest metal samples by using microwave method compared with conventional wet digestion method. Digestion time for metal samples was four to six hours long for wet digestion, while one hour long for microwave digestion. Determinant coefficients of Cu, Mn, Zn, Ca, K, and Mg contents between two analyzing methods were 0.99, 0.99, 0.94. 0.97, 0.98, and 0.91, respectively. In the case of Ca and K, microwave digestion method analyzed their contents relatively low compared with wet digestion method. Meanwhile, microwave digestion method analyzed the contents for Cu, Ma, and Zn relatively high compared with wet digestion method. This study results in that microwave digestion method could be an alternative to replacing conventional wet digestion method.

Gasification and melting method is one of the most potential means for waste treatment process with low emission of fly ash or heavy metal, dioxin and high possibility of using slags as resources. Moisture contents influences directly a gasification characteristics of waste. So it is necessary to investigate the effect of moisture contents in gasification. But it is hard to consider the effect of moisture contents, using samples of powder form of Milligram's order in existing thermogravimetric analyser. Therefore, we made a thermogravimetric analysis device to applicate samples of Gram's order. Gasification characteristics are typically reported with result from thermogravimetric analysis date for wood and RDF samples along with changing moisture contents. It is discussed the way to apply these analysis results to gasification and melting furnace.

Diversity of 30 Korean potato cultivars was evaluated using 14 microsatellite markers. Twelve microsatellite markers representing 12 loci in the potato genome detected 84 polymorphisms among 30 cultivars and revealed alleles with a mean of 7.00 alleles per primer. The polymorphism information content (PIC) value ranged from 0.57 to 0.93 with average of 0.82. Based on polymorphism, cluster analysis was conducted by the unweighted pair-group method with arithmetic average (UPGMA) methods. Thirty potato varieties were distinctly separated into 2 groups and similarity coefficient of cluster ranged from 0.58 to 0.95. Thirty tetraploid cultivars were evaluated for six important agronomic traits. One-way analysis of variance was done to look for the degree of relationships between individual markers and traits. K1 and K2 markers showed a significant association with amylose contents, starch contents, and specific gravity.

Objective : Licorice has been used for treating digestive disorder and also recommended as a detoxification agent. Liquiritigenin, a component of licorice, has been reported to have various biological activities. In this study, we aimed to establish the analytical method for liquiritigenin content in licorice and the processing method for the enhancement of liquiritigenin content in licorice. Methods : Processing was accomplished by roasting licorice at $250^{\circ}C$ for indicated time periods (5-20 min). Analysis of liquiritigrnin from roasted licorice was conducted using UPLC(Ultra Performance Liquid Chromatography). Results : We established UPLC method for the analysis of liquiritigenin using water : acetonitrile gradient as mobile phase. Furthermore, we standardized the processing condition of licorice to enhance liquiritigenin content using UPLC method. Processing of licorice was accomplished by roasting at $250^{\circ}C$ for indicated time periods (5-20 min) and by pretreating with 50% of acetic acid or 30% ethanol for 24 h. By roasting licorice, the liquiritigenin contents in the licorice were increased. The best roasting time of licorice was 6 min, while roasting for the time above 8 min resulted in diminishing liquiritigenin contents. Moreover, pretreatment with 50% of acetic acid or 30% ethanol picked up liquiritigenin contents in roasted licorice. Conclusion : The adequate processing condition of licorice for the enhancement of liquiritigenin contents was obtained by pretreating licorice with 50% of acetic acid or 30% ethanol for 24 h and then by roasting at $250^{\circ}C$ for 6 min.

This study was carried out to develop the method of alkaloids analysis and investigate the kinds and contents of alkaloids in flue-cured, burley and oriental tobacco leaves using developed analytical method. The developed analytical method of alkaloids was as followed : Tobacco sample was treated with acid(pH 2∼3) and extracted with chloroform to remove chemical components except alkaloids. Sample solution was treated with alkali(pH 12∼ 13) and was extracted with chloroform to obtain alkaloids from sample solution. After extraction of alkaloids from tobacco leaves, alkaloids were separated and identified by GC, GC/MS using SE-54 fused silica capillary column. Nicotine, nornicotine, myosmine, 9-nicotyline, anabasine, anatabine, 2, 3-bipyridyl, cotinine, formyl nornicotine, acetyl nornicotine and formal anatabine were isolated and identified from the extracts of tobacco leaves. The contents of alkaloids were burley > flue-cured > oriental tobacco leaves, but oriental tobacco leaves were higher nornicotine, cotinine, formyl nornicotine and acetyl nornicotine contents than those of flue-cured tobacco leaves. The burley tobacco harvested in Korea was higher nornicotine contents by 2-6 times in the portions of cutter, leaf and tips position than that of burley tobacco(B3F) harvested in V. S. A.

Musculoskeletal disorders show symptoms of pain and dysfunction caused by accumulation of minute damage on nerves and blood vessels which are related to specific body parts. This is more likely to occur in the elderly. In Korea, 40.3% of the agricultural population is over 65 years old. In these cases, the portion of musculoskeletal disorders is more than 80% in acute/chronic diseases related to agricultural work. Therefore, measures for physical health care and safety prevention of elderly farmers are needed. In this study, we intend to propose a method to measure musculoskeletal health condition through the motion recognition device and VR contents. For this, we analyze the agricultural work causing musculoskeletal disorders of farmers, and suggest a motion analysis algorithm that can measure the health condition of the musculoskeletal system. In addition, we are going to propose a training method customized for farmers on the basis of VR contents in order to prevent musculoskeletal disorders.

The thing that is the most important at time to produce the culture contents is developing source story and storytelling which is work to process in the contents of various media. However, the study of the methodology for the interest element design of storytelling which is necessary to produce the culture contents is insufficient. Therefore, this article is going to show a design method, when I plan the culture contents of the OSMU base, which is analysis the pleasure element of storytelling to make an interesting story and visual storytelling to visualize the pleasure elements.
