This study has an objective to analyze the causal relationship between the business resource of the members in the Airport Special Guard's firms and its effect on their business attitude and turnover intention. To carry out the study, I established a population of Airport Special Guard's working at the Airport firms in In-cheon, Kim-po, Cheong-ju and Dae-gu. Then a total of 300 questionnaires were sent out for the survey using the random sampling method of clusters. The study was carried out over about four months, from July, 2016 to october, 2016. A total of 260 questionnaires were used for the final data. 40 questionnaires were excluded either because they were not returned or contained extreme value. In this study, a statistical package of SPSS WIN 18.0 were used in the data analysis and the causal relationship was verified using the multiple regression analysis. The analysis showed the business resource to have a positive effect on the business attitude but a negative effect statistical level of p<.01 on the turnover intention at the statistical level of p<.001 and the hypothesis was adopted. The hypothesis regarding the business attitude was also adopted because business attitude was found to have a negative effect on the turnover intention at the statistical level of p<.01. In addition, business attitude was found to have a negative effect on the relationship between the business resource and turnover intention at the statistical level of p<.05. As a result, the hypothesis about the business attitude would function as the parameter was only partially adopted. Through these research result, it was investigated that the relation between business resource, business attitude and turnover intention is significantly effective variable in airport special guard's. Additionally, business resource is the most important.

This study is a follow-up study of vulnerable areas according to the vulnerability assessment of groundwater resource management in Korea. In this study, an optimal operation plan for groundwater resource management was proposed for areas vulnerable to groundwater resource management in Korea derived from previous studies. Prior to presenting the optimal operation plan for groundwater resource management, this study grasped the current status of changes in groundwater level and seawater penetration area for vulnerable areas using MODFLOW, a groundwater flow analysis program. As a result of the analysis using basic data for 10 years from 2009 to 2018, the groundwater level fell and the sea infiltration area increased. The final purpose of this study, the optimal operation plan for groundwater resource management, was selected as a total of four alternatives that can be expected to have positive effects to increase groundwater level and reduce seawater penetration. As a result of analyzing the amount of change in groundwater level and seawater penetration by applying the selected optimal operation plan, positive effects were found in all methods. It is expected that the optimal operation plan for groundwater resource management proposed in this study will be applied not only to vulnerable areas of groundwater resources in Korea but also to areas requiring development to establish efficient groundwater resource management measures.

The aim of this study was to evaluate the potential of fermented red ginseng extract (FRGE) as feed additive in broilers and laying hens. In broilers, 480 Arbor Acre male broilers were randomly allotted to 4 treatments with 6 replications per treatment and 20 chicks per pen. The experiment lasted 5 weeks and dietary treatments were as follows: i) CON, basal diet; ii) FRGE1, basal diet+1 g/kg fermented red ginseng extract; iii) FRGE2, basal diet+2 g/kg fermented red ginseng extract and iv) FRGE3 basal diet+4 g/kg fermented red ginseng extract. Throughout the experiment, no effects were observed (p>0.05) in performance in response to FRGE. At the end of the experiment, FRGE administration improved (p<0.05) the lymphocyte level compared with CON. The relative weight of bursa of fabricius and spleen were increased (p<0.05) by the inclusion of FRGE3. Besides, redness ($a^*$) value for the breast meat was higher (p<0.05) in FRGE1 and FRGE3 treatments than that in CON. In laying hens, 240 ISA brown layers at 35 weeks of age were used in this 8-week trial. Dietary treatments were the same as in the broilers trial with 10 replicates per treatment and 6 layers per replicate. During the entire experiment, there were no significant differences (p>0.05) in performance or egg quality among all the treatments. However, the layers fed diets supplemented with FRGE had higher lymphocyte level (p<0.05) compared with those fed CON. In conclusion, the dietary supplementation with FRGE did not influence performance but improved the lymphocyte level in both broilers and laying hens.

We conducted this 10-wk experiment to evaluate the effects of dietary phytoncide, Korean pine extract as phytogenic feed additive (PFA), on growth performance, blood characteristics, and meat quality in finishing pigs. A total of 160 pigs ([Landrace${\times}$Yorkshire]${\times}$Duroc, body weight (BW) = $58.2{\pm}1.0kg$) were randomly allocated into 1 of 4 treatments according to their BW and sex, 10 replicate pens per treatment with 4 pigs per pen were used (2 barrows and 2 gilts). Dietary treatments were: CON, control diet; PT2, CON+0.02% PFA; PT4, CON+0.04% PFA; PT6, CON+0.06% PFA. Overall, average daily gain (ADG) was higher in PT4 (p<0.05) than in PT6, average daily feed intake (ADFI) was lower in PT6 than in CON (p<0.05). Besides ADFI decreased linearly (p<0.05) with the increased level of phytoncide and gain:feed ratio in PT4 treatment was higher (p<0.05) than CON treatment. During 5 to 10 weeks and overall, quadratic (p<0.05) effect was observed in ADG among the treatments. At the end of this experiment, pigs fed with PT4 diet had a greater (p<0.05) red blood cell concentration compared to the pigs fed CON diet. Water holding capacity increased linearly (p<0.05) with the increased level of phytoncide supplementation. Moreover, firmness, redness, yellowness, and drip loss at day 3 decreased linearly (p<0.05) with the increase in the level of phytoncide supplementation. In conclusion, inclusion of phytoncide could enhance growth performance without any adverse effects on meat quality in finishing pigs.

This paper proposes a low power resource allocation and scheduling algorithm that minimized power consumption such as DSP circuit in high-level synthesis process. In this paper, we have used list-scheduling method for low power design in scheduling step. Also, it increase possibility to reuse input through resource sharing when assign resource. After scheduling, the resources allocation uses the power function in consideration of the result of calculating average hamming distances and switching activity between two input. First, it obtain switching activity about input value after calculate average hamming distances between two operator and find power value make use of bit pattern of the input value. Resource allocation process assign operator to minimize average hamming distance and power dissipation on all occasions which is allocated at each control step according to increase control step. As comparing the existed method, the execution time becomes fast according to number of operator and be most numberous control step. And in case of power that consume, there is decrease effect from 6% to 8% to be small.

The purpose of this study is to resolve the factors that affect happiness levels and leisure life satisfaction of middle-class and to find way to incorporate them into policy. In this study, a status analysis on leisure life and One-Way ANOVA conduct a study on leisure resource and income levels that affect the happiness level and leisure life satisfaction. To recap briefly, to reduce the social and cultural polarization caused by economic disparity and to promote leisure life satisfaction and happiness level is possible quantitative-qualitative growth and maturation of middle class. The most important thing here is increasing in leisure time and leisure costs that consumed in real leisure life. In other words, leisure life satisfaction and happiness levels in the middle class has seen a significant difference in depending on whether and how much to spend on leisure time and cost, rather than differences of the monthly average household income. More particularly, analysis results seem to hoping of the extra leisure costs about 50,000 won per person and increasing the leisure time on weekdays and long weekend holiday. Above all, It is important to redefine the middle class that meets the recognition of the people and it should reflect government policy. Ultimately, The state of the socio-economic-welfare policies will be further expanded in the direction for the middle class, thinking of themselves as middle class and leading national consciousness.

Using materials recovered from the waste stream instead of virgin resources as a raw material in manufacturing has great environmental and economic benefits. However, there is lack of public interest in needs for integrated waste management and its relevant facilities, because of NIMBY syndrome, This article has proposed a system dynamics model for the study of the potential and systemic consequences of resource circulation management system(RCMS) policy for a Sudokwon landfill site in Korea. The results of the study indicate that the effects of RCMS are seen continuously to increase in term with both the community welfare level and the resource and energy level. Moreover the effects of RCMS appear sharply in the first half of the simulation period.

This paper proposed resource allocation algorithm for the minimum switching activity of functional unit in high level synthesis process as like DSP which is circuit to give many functional unit. The resource allocation method after scheduling use the power function calculating average hamming distance and switching activity of the between two input. First of all, the switching activity is calculated by the input value after calculating the average hamming distance between operation. In this paper, the proposed method though high If level simulation find switching activity in circuit each functional unit exchange for binary sequence length and value bit are logic one value. To use the switching activity find the allocation with minimal power consumption, the proposed method visits all control steps one by one and determines the allocation with minimal power consumption at each control step. As the existing method, the execution time can be fast according to use the number of operator and max control step. And it is the reduction effect from 6% to 8%.

This paper proposes a novel traffic and resource management scheme based on Service Level Agreement (SLA) which allows to guarantee the quality of experience (QoE) for various high-quality mobile multimedia service users to a certain level. For this purpose, QoE-SLA coupling structure is considered and a novel scheme is suggested to suppress the processing delay of the mobile terminal and to decrease the transfer delay in the transmission network. According to simulation results, our proposed scheme can increase the total throughput and decrease the average delay by adjusting SLA.
