Despite the importance of the management of food and beverage, most managers in hotel and restaurant have taken little interests in the menu planning and management processing. Recently, people are more interested in what they eat and drink and thus related industries are in harsh competition. These are resulted from the newly introduced 5-work-day system and growing concerns of people on the quality of life. From these concern, the menu composition must be the critical matter. I examine the significance of the menu composition by regression analysis on two factors, i.e. satisfaction level of employees and effectiveness of work. The outcome proved the positive effect of menu composition on them. Therefore, more studies on menu composition are required.

This thesis aims to analyze the visual perceptual effects drawn by 'axial composition and divergence' and to interpret the architecture of Kahn in respect of 'axial composition and divergence'. Axial composition of the form, the location of the entrance and divergence of internal movement were checked up about 53 works by extracting parti which is basic element of spatial composition. The 3D modeling simulation was performed for the selected 10 works in order to analyze the visual perceptual effect due to divergence of the internal movement. The reaction of the observer's actions and visual perception by 'axial composition and divergence' is presented in the following steps. 1. Divergence of the entrance/a panorama of expanding planes. 2. Divergence of internal movement/The process of perception of visual rotation and central spatial form. 'Perceptive form' created by 'divergence' is the result of diverse and flexible series of processes which must be experienced in person in order to reach the space as a room with a definite domain and center.

Purpose: This study investigated the changes in body composition and serum lipid composition in obese women that were caused by a 12-week circuit exercise regime including both field and aquatic activities. Methods: Subjects comprised a total of 36 women who had a BMI of more than $25kg/m^2$. The simple obesity group (n=17) had no current or past record of medical complications, whereas the group with complications (n=19) also suffered from hypertension and/or diabetes. The circuit exercise program consisted of 12 weeks of 60%HRmax exercise sessions, five days a week. Results: While changes in every variable of body composition were significant, there was no statistically significant difference in the changes in serum lipid composition variables. With the exception of BMI, the correlation between the simple/complicated groups and exercising was statistically insignificant. Conclusion: These findings suggest that while a complex circuit weight exercise program that includes aquatic exercises significantly and positively alters obese patients' body composition it does not create statistically significant changes in their serum lipid composition. It can still be concluded, however, that increasing the duration of the exercise program would be effective to influence this. Moreover, personalized exercise programs that fit the needs of the individual participants seem necessary, given that the effect of exercise on body composition and serum lipid composition was greater in patients with simple obesity than in those with complications.

The effect of temperature and ethanol concentration on lipids yield and free fatty acids were investigated during 1-5 times of 8 hours extraction. The crude lipids recovered was generally increased as the ethanol concentration increased while it was decreased at higher extraction temperature. Fatty acids composition in free fatty acids showed linoleum and plasmatic acids to be the major fatty acids, accounting 60% of 16 fatty acids identified. Fatty acids pattern was little affected by the changes in ethanol concentration while increase in temperature resulted significant changes in fatty acids composition.

지방산 조성은 고기의 풍미에 영향력 있는 중요한 경제 형질 중 하나이며, 다양한 유전자들의 효과가 알려져 있다. 본 연구는 한국 재래닭의 지방산 조성에 유의적인 영향을 미치는 것으로 조사된 6개의 후보 유전자들(DEGS1, ELOVL6, FABP3, FABP4, FASN, SCD)의 51개 SNP 조합에 대한 추가적인 분석결과로, 선행연구를 통하여 확인된 SNP 조합들이 가지는 상위성 효과에 대하여 조사하였다. 본 연구를 통하여 매우 다양한 유형의 SNP 조합들이 한국 재래닭의 지방산 조성에 영향을 미치는 것으로 확인되었으며, 추후에 지방산 조성과 같은 다유전자성 형질들을 실제 육종 프로그램에 활용하기 위해서는 이러한 분석이 이루어져야 될 것으로 생각된다. 본 연구 결과는 한국 재래닭의 육질, 특히 지방산 조성의 개선을 위한 유전학적인 정보를 제공할 수 있을 것으로 생각된다.

$CO_2$ is a well-known green house gas, which is the major source of global warming. Many researchers have studied to reduce $CO_2$ emission in combustion processes. Among the method for reducing $CO_2$ emission, oxygen-enriched combustion has been proposed. But the adiabatic flame temperature is too high. So existing facilities must be changed, or the adiabatic flame temperature in the combustion zone should be reduced. The combustion characteristics, composition in the flame zone, temperature profile and emission gases were studied experimentally for the various oxygen-enriched mtios(OER) by addition of $CO_2$ under coustant $O_2$ flowrate. Results showed that the reaction zone was quenched, broadened, as addition of $CO_2$ was increased. Temperature has a large effect on the NOx emission. The emission of NOx in flue gas decreased due to the decreased temperature of reaction zone. It was also shown that the reaction was delayed by the cooling effect. As the addition of $CO_2$ was increased, the composition of CO in the flame zone increased due to the increase of reaction rate by increasing mixing effect of oxidant/fuel at OER=0, but the composition of CO decreased by quenching effect at OER=50 and 100%.

There is limited information of the genetic effect for fatty acid composition in chicken meat. This study assessed the association of FABP3 and FABP4 genes affecting fatty acid composition in broilers. Two single nucleotide polymorphisms (SNPs) were detected in FABP3 gene and five SNPs were identified in FABP4 gene. The SNPs located in intron 1 and exon 1 of FABP3 and FABP4, respectively, were used for genotyping using PCR-RFLP method. The SNPg.285C >T in FABP4 showed suggestive association with high arachidonic acid (C20 : 4) in CT genotypes (P = 0.068). However, the SNP g.508C > T in FABP3 showed no significant associations with fatty acid composition. These results are the first report to investigate the SNPs in FABP3 and FABP4 genes and their associations with fatty acid composition, although we only found the possible association of FABP4 SNP with fatty acid composition. These results should provide valuable information for further investigation of the genes affecting fatty acid composition in chicken.

1. Dry matter intake was significantly increased above the 30% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and dry matter intake, and was a significant negative correlation (p<0.05) between the content of NDF and dry matter intake. 2. Dry matter digestibility was significantly increased with the increase of red clover plant composition as compared with 100% orchardgrass plant composition (p<0.05). Digestible dry matter intake was significantly increased above the 20% red clover plant composition (p<0.05) as compared with 100% orchardgrass plant composition. However, there was a significant positive correlation (p<0.05) between the content of CP and digestible dry matter intake, and was a significant negative correlation (p<0.01) between the content of NDF and digestible dry matter intake. 3. Preference of herbage samples tended to markedly increased with the increase of red clover plant composition.
