In order to investigate the appropriate processing season of ark shell(Scapharca subcrenata) cultured at the south coast of Korea, the edible portions were determined for coefficient of fatness and yield of edible portion using specimens collected bimonthly from December 1994 to December 1995. The relationship between shell length(X) and total weight(Y) of S. subcrenata is shown as follows; Y=0.001608X2.5199. The relationship between total weight(X) and meat weight(Y) of S. subcrenata is shown as follows; Y= 0.3594X 0.5566(r=0.99). The relationship between total weight(X) and meat weight(Y) of S. subcrenata is shown as follows; Y=67.1647X＋20.6370(r=0.99). The coefficient of fatness and yield of edible portion showed a marked bimonthly variation with a maximum in December and a minimum in August. The appropriate processing season of S. subcrenata would be in winter and spring, and not in summer and autumn season, the spawning season of the S. subcrenata.

The results of this numerical model is usable to analysis for the phenomena of precipitation during the periods of a rainy season in the Northeastern Asia. Case l(start of rainy season) dominates over precipitation by the processing of convection from the equator region through the East China region, and then the most of water vapor is transported by the processing of advection from the India-monsoon region to this study region. Case 2(heavy rainy season) faints precipitation by the processing of convection in the Korean peninsula, but dominates precipitation by the processing of microphysics. the water vapor originates from the India-monsoon region.

In order to determined the appropriate processing season of Pacific oyster (Crassostrea gigas), 30 individuals cultured in Kamak Bay on the southern coast of Korea were taken bimonthly 7 times a year, and seasonal variation of edible portion weight, edible portion yield and coefficient of fatness were investigated. There were close relationships between edible portion weight (X) and total weight (Y) and between coefficient of fatness (X) and edible portion yield (Y), which were expressed in regression lines, i.e. Y=0.2709X-1.9094 (r=0.9254) and Y=44.0596X+ 15.1127 (r=0.8485), respectively. From the results of seasonal variation of edible portion weight, yield and coefficient of fatness, the appropriate processing season of raw Pacific oyster was between winter and spring, that is, between December and following April the next year.

In order to investigate the appropriate processing season and the production of high value-added products in ark shell(Scapharca subcrenata) cultured at the south coast of Korea, the foot muscle, mantle, and adductor muscle were analyzed for moisture, protein, fat, ash, and glycogen using specimens collected bimonthly from December 1994 to December 1995. The contents of moisture in foot muscle and mantle increased in spring season, however their proteins decreased in same season. Glycogen and fat in foot muscle, mantle, and adductor muscle were most abundant in June, just before the spawning season, but all the cmponsnts dwindled during spawning season. The other hand, the contents of ash in tissues were almost the same level through the year. Thus, the contents of moisture, protein, fat, and glycogen were almost the same level through the year. Thus, the contents of moisture, protein, aft, and glycogen were fluctuated by season. Especially, they showed a marked seasonal variation at before and after sparning season. So, a major cause of seasonal variation in S. subcrenata would be connected with a period of reproduction and spawning season.

The levels of aflatoxin (AFT) and ochratoxin (OCT) were assessed at different seasons in raw materials, different feed manufacture processing stages, and animal feeds in feed mills in Korea implementing the hazard analysis and critical control point (HACCP) system. Two hundred samples were collected in all four seasons from five feed mills implementing the HACCP system and examined for AFT and OCT contents. The AFT and OCT levels were analysed by using HPLC method to provide information on raw material and product stage. The AFT content of raw ingredients in the spring season was highest in corn gluten (3.84 ppb) and lowest in corn (1.82 ppb) The AFT content of corn was highest in the winter season (2.17 ppb). The content of OCT in wheat was highest in the winter season. The amounts of AFT and OCT at processing stages were higher than in the raw materials or feed. In particular, AFT content was higher in the transfer stage (3.88 ppb) than in the mixing (2.86 ppb) or filling stages (3.45 ppb) in the summer season. The means of AFT and OCT level in laying hen feed was 3.41 ppb and 1.14 ppb for broiler feed, respectively. The means of AFT and OCT level in and broiler feeds was 3.44 ppb and 1.17 ppb for broiler feed, respectively.

Fabrics created unique features through the change in various ways depending on the elements including fabric structure, threads, thickness, weaving, patterns and processing. This study examined the difference between texture and image depending on components of fabrics. In order to understand the trend of components of fabrics, the actual components of fabrics was analyzed by year, using the women's apparel trend books, Nelly Rodi Fabrics and Promostyl Fabrics. This study analyzed Spring/Summer season and Fall/Winter season from 2002 to 2012. Frequency analysis, cross-tabulation analysis, multiple response cross tabulation analysis were implemented using SPSS 18.0. The followings are the analysis results. For fabric composition, Spring/Summer season used cotton fabric the most. Cotton fabric accounted for relatively high usage in 2005, 2007 and 2008. Fall/Winter season used wool the most in 2002, 2003, 2004 and 2005. In case of fiber blend by fabric composition, cotton was blended with other fibers in Spring/Summer season except wool. The fiber blending ratio of wool was the highest in Fall/Winter season. Wool was blended in most fabrics. More than two patterns were mixed for fabric patterns. The fabric patterns were applied the most in 2012. For fabric processing, the fabrics by sensitivity-functional processing were continuously used every year and the surface finish showed relatively high usage in 2002 and 2011. In conclusion, this study will build the systematic data for 11 years including fabric trends in the past. It can improve specialization, systematization and efficiency in fabric planning.

This research was to evaluate microbial contamination levels in meat samples at hazard analysis critical control point (HACCP)-implemented processing plants that produce beef, pork, and chicken. During a period of about a year, a total of 178 samples (76 from beef, 89 from pork, and 13 from chicken) were obtained from raw materials (21.3%) and final products (78.7%). All samples were determined for each 25 g homogenized one. Samples were analyzed to determine the total aerobic plate count (APC), coliform count (CC), and E. coli count (ECC). By month, APC levels were the highest in September and the lowest in February (p<0.001). In comparison among season, APC levels in meat samples were the highest in the summer and the lowest in winter (p<0.001). By month, the highest CC prevalence was found in August, followed by October and then July (p<0.001). By season, the highest CC was obtained in summer, followed by autumn and then spring (p<0.001). All samples were negative for ECC. There was a direct correlation between the product form and coliform presence (p<0.001). In addition, there was a positive correlation between the APC and CC (r=0.261). The APCs in analyzed samples ranged from below <$10^1CFU/g$ to <$10^7CFU/g$. In conclusion, the month and season had significant effects on microbial contamination levels at HACCP implemented processing plants. Interrelationships between (i) the product form and coliform, (ii) the APC and CC were revealed.

The Pythagorean theorem for baseball based on the number of runs they scored and allowed has been noted that in many baseball leagues a good predictor of a team's end of season won-loss percentage. We study the convergence characteristics of the Pythagorean expectation formula during the baseball game season. The three way ANOVA based on main effects for year, rank, and baseball processing rate is conducted on the basis of using the historical data of Korean professional baseball clubs from season 2005 to 2014. We perform a regression analysis in order to predict the difference in winning percentage between teams. In conclusion, a difference in winning percentage is mainly associated with the ranking of teams and baseball processing rate.

This study was performed to develope the method of wildgrass to process as hydroseeding material which is a most popular revegetation method for Slope areas through the control of soil eroison and stability by seeding grasses. The wildgrass material for the processing were harvested at Suwon, Kyungki-do and Wonju, Kangwon-do in 1994. The investigations were established in laboratory for pot and field experiment with seven treatments by harvesting date and place in 1995. Results indicated that wildgrass harvested field in open space or road side was able to be used as hydroseeding material by proper processing. It was possible to substitute wildgrass seed to conrrnercial turfgrass seed, and plant tissue to mulching fiber by drying and crushing process. Germination of wildgrass seed was relatively slower than control (20g /$m^2$ turfgrass seed) in early stage of 20 days, but surface revegetation rate was higher in 50 days at wildgrass plot than control applied by normal hydroseeding method. Mixture of 5g /$m^2$ of cool season turfgrass seed to wildgrass material increased the rate of early stage of germination and surface revegetation. The application of wildgrass as hydroseeding material showed more naturalistic scenery than rutine hydroseeding with imported cool season turfgrass seed. Key words: Rydroseeding, Turfgrass, Wildgrass, Revegetation.

With improvements in living conditions, an increasing number of people are choosing to spend their time traveling. Comfortable tour routes are affected by the season, time, and other local factors. In this paper, the influencing factors and principles of scenic spots are analyzed, a model used to find the available routes is built, and a multi-route choice model based on a game theory utilizing a path recommendation weight is developed. A Monte Carlo analysis of a tourist route subjected to fixed access point conditions is applied to account for uncertainties such as the season, start time, end time, stay time, number of scenic spots, destination, and start point. We use the Dijkstra method to obtain multiple path plans and calculate the path evaluation score using the Monte Carlo method. Finally, according to the user preference in the input path, game theory generates path ordering for user choice. The proposed approach achieves a state-of-the-art performance at the pseudo-imperial palace. Compared with other methods, the proposed method can avoid congestion and reduce the time cost.
