The goal of this study was to find out the effective diet prescription for the exercises. To accomplish this purpose, we investigated the effect of free-fatty acid diet (FFAD) on two groups of the K technical high school soccer players; one group with 7 members for normal diet (NORD) and another group with 7 members for high-fat diet (HFD). HFD group was fed far three days before the game. Results were as follows: i) Blood glucose level was increased with statistical significance in HFD group (P<.01) compared to the NORD group. After plying game, the glucose level was increased in the both groups ii) The contents of free-fatty acid (FFA) was significantly increased in HFD group (P<.0001) compared to the NORD group. After playing game, the FFA level was also increased in both groups iii) The levels of T-C, HDL-C and LDL-C were slightly increased in both NORD and HFD groups after playing game, while the TG level was slightly decreased. However, the differences were not significant. These results imply that HFD may not affect the level of seam lipids. Overall, the level of glucose and FFA were increased, but other types of lpids were not changed. From these studies, we observed the increase in the level of glucose and FFA but not other sew lipid. These results indicate that HFD may induce the body energy-utilizing system during long-lasting exercise such as playing soccer game.

This study is aimed at investigating optimum level of payments in the direct payment program for aquaculture extruded pellets both theoretically and practically by analyzing the effects on production and income in accordance with Green Box conditions of WTO Agreement on Agriculture. In particular, by analyzing both effects on production and income, it evaluates and compares payments affecting to the level of production and income, respectively. Analysis results indicate that the optimum level of payments in the direct payment program for aquaculture extruded pellets is determined by the growth rate of farmed fish, farming period, price and volume of extruded pellets, and additional amount of cost increase and decrease. Suppose that growth rates of farmed fish by extruded pellets(EP) and raw fish - based moist pellets(MP) are the same, it reveals the optimum level of payment should be lowered from the current level of payment. However, when the growth rate of farmed fish by EP is lower than that by MP, the optimum level of payment should be raised from the current level and total amount of payments by area should be increased as well.

A fuel tank contains water at the bottom under the fuel. The water comes from humidity by temperature change of inside and outside of tank. So it is necessary to measure both level to check precise amount of oil. But measuring instrument for level of water and fuel is not available yet. Since the fuel is inflammable, the sensor system must not include any electric circuits in the fuel tank. Optical cable sensor can satisfy this non-explosive condition. The displacement of a float changing by water level makes bending curvature of optical cable different. As the float rise up, the optical cable is bent more and the light signal in the cable decreases. The reduction of light signal is detected and it is converted into the change of water level. The output signal from a photo diode shows the proportional relation of water level. The increase of sensor voltage as a unit of ㎷ follows the level position of the float that is located between water and gasoline in the tank.

In defense domain, mission level and engagement level simulation tools exist. In order to experiment a simulation scenario for obtaining results of both mission level and engagement level simulations, we should write a same simulation scenario in a mission level simulation tool as well as an engagement level simulation tool, and we have to operate these tools for analysis of each purpose. Moreover, we could not guarantee that these scenarios are completely same since each scenario is composed of different fidelities of simulation models, although the scenarios are written by a same experimenter and with same simulation purpose. To deal with the difficulties, I propose an approach to analysis of both mission level and engagement level simulations from one simulation result. For this, I have built Composite Combat Mission Planning Simulation Environment (CCMPSE). In this paper, the HLA/RTI based simulation composition technology and my experiences for the designed Composite Combat Mission Planning Simulation Control System (CCMPSCS) are explained. Moreover, This paper also conducts a case study with EADSIM, SADM, and the CCMPSCS. Finally, this paper provides lesson learned from the case study.

The purpose of this study is to analyze the relationship of logical thinking skills and integrated process skills, and to investigate the differences in general tendency of subskills by grade level and gender between Korean middle school students and Japanese one. The performance level of skills was measured using GALT and TIPS II. The results are compared with those of Japan (Mattheis et al., 1992). Summary of the results are as follow. 1. Percentages of formal and transitional stage of males are more than females in developmental level. It has been found out that the males attained significantly higher scores of logical thinking skills than the females in middle school stage. The significant differences in scores by gender show a good correlation with those for Japanese middle school students. Developmental level of Korean middle school students shows a remarkable improvement as they move up from 8th grade to 9 one. The significant differences in developmental level by grade also show a good correlation with those for Japanese middle school students. Total scores of GALT for Japanese middle school students are higher than Korean one, but it has been found nearly same scores for 9th grade in both countries. Scores of subskills of logical thinking skills, except correlational reasoning, for Korean students show lower than those for Japanese students. It could be noted that the combinatorial reasoning is considered to be easiest and the correlational reasoning to be most difficult in both countries. 2. It also has been found out similar pattern for integrated process skills in both countries because the males and females did not examplify significant differences, although males gain somewhat higher scores than females in Korea. Scores of subskills of integrated process skills for Japanese middle school students show higher them Korean one. It could be noted that the identifying variables is considered to be easiest and stating hypothesis to be most difficult in both countries. 3. There was a significant relationship (r= .65) between logical thinking skills and integrated process skills, and there were statistically significant differences of the integrated process skills for developmental level. In integrated process skills, the students who belong to the higher grade levels acquired better score than who belong to the lower grade level. It has been also found remarkable improvement between 8th and 9th grade, and there are significant differences for grade level in both countries.

In an attempt to simultaneously produce two human proteins, hGH and hG-CSF, in the milk of transgenic mice, we constructed goat $\beta$-casein-directed hGH and hG-CSF expression cassettes individually and generated transgenic mice by co-injecting them into mouse zygotes. Out of 33 transgenic mice, 29 were identified as double transgenic harboring both transgenes on their genome. All analyzed double transgenic females secreted both hGH and hG-CSF in their milks. Concentrations ranged from 2.1 to $12.4\;mg/m{\ell}$ for hGH and from 0.04 to $0.13\;mg/m{\ell}$ for hG-CSF. hG-CSF level was much lower than hGH level but very similar to that of single hG-CSF mice, which were introduced with hG-CSF cassette alone. In order to address the causes of concentration difference between hGH and hG-CSF in milk, we examined mRNA level of hGH and hG-CSF in the mammary glands of double transgenic mice and tissue specificity of hG-CSF mRNA expression in both double and single transgenic mice. Likewise protein levels in milk, hGH mRNA level was much higher than hG-CSF mRNA, and hG-CSF mRNA expression was definitely specific to the mammary glands of both double and single transgenic mice. These results demonstrated that two transgenes have distinct transcriptional potentials without interaction each other in double transgenic mice although two transgenes co-integrated into same genomic sites and their expressions were directed by the same goat $\beta$-casein promoter. Therefore goat $\beta$-casein promoter is very useful for the multiple production of human proteins in the milk of transgenic animals.

Purpose: This study was to compare job stress and job satisfaction between ward nurses and outpatient nurses, and to identify the correlation between job stress and job satisfaction. Methods: The subjects of this study were 200 ward nurses and 85 outpatient nurses in G and I University Hospital in Incheon. The data were collected in March 2010 and analyzed with t-test and Pearson correlation coefficient. Results: There was no significant difference in overall job stress between two groups, but slightly higher stress level for ward nurses. In sub-area of job stress, 'nursing duty' was primary for both groups. And in 'nursing duty' (t=2.05, p=.041), 'conflict with patients' (t=2.73, p= .007), and 'working environment' (t=3.37, p<.001) ward nurses showed significant higher level of stress than outpatient nurses. For job satisfaction, outpatient nurses showed higher level significantly (t=-2.98, p=.003). And both groups of nurses' job satisfaction was negatively correlated with job stress significantly (r=-.31, p<.001). Conclusion: It will be possible to reduce job stress and promote job satisfaction level for both groups of nurses by adding staffs, and specifically for ward nurses by improving facilities for relax and appropriate supply, and for outpatient nurses by managing interpersonal stress and reducing side tasks.

The purposes of this study were to compare the reliability and validity of an 88-item version of the Gross Motor Function Measure (GMFM-88) and a 66-item version of GMFM (GMFM-66) in children with cerebral palsy (CP). The GMFM was completed in 154 children with CP (age range = 6~12). The internal consistency of the GMFM was calculated by Cronbach's ${\alpha}$ for judging reliability. The reliability of GMFM-88 and GMFM-66 were both above .99. The validity of measurement obtained by the GMFM was assessed by examining the unidimensionality of items and by comparing Gross Motor Function Classification System (GMFCS) levels with tests of the GMFM. Both the GMFM-88 and GMFM-66 were satisfied with unidimensionality. Discriminant validity was demonstrated on significant decreases in scores with increasing GMFCS levels in both measurements. However, GMFM-66 was a more sensitive discriminant in GMFCS level 1 and level 2 and in level 2 and level 4. This study reported a comparison of the reliability and validity of GMFM-88 and GMFM-66. The results of this study have implications for the information on the psychometric properties of two versions of GMFCS. This information will be useful for the selection of tools in clinics.

The present study aims to investigate neural activations according to the level of code switching in English proficient bilinguals and to find the relationship between the performance of language switching and proficiency level using ERPs (event-related potentials). First, when comparing high-proficient (HP) with low-proficient (LP) bilingual performance in a native language environment, the activation level of N2 was observed to be higher in the HP group than in the LP group, but only under two conditions: 1) the language switching (between-language) condition known as indexing attention of code switching and 2) the inhibition of current language for L1. Another effect of N400 can be shown in both groups only in the language non-switching (within-language) condition. This effect suggests that both groups completed the semantic acceptability task well in their native language environment without the burden of language switching, irrespective of high or low performance. The latencies of N400 are only about 100ms earlier in the HP group than in the LP group. This difference can be interpreted as facilitation of the given task. These results suggest that HP showed the differential activation in inhibitory system for L1 in switching condition of L1-to-L2 to be contrary to inactivation of inhibitory system for the LP group. Despite the absence of an N400 effect at the given task in both groups, differential latencies between the peaks were attributed to the differences of efficiency in semantic processing.
