With the targeted coffee consumers in Kwangju city, South Korea, this paper investigates a few determinants such as taste, aroma, mouth-feel, and satisfaction to influence coffee price, based upon self-evaluations by those who enjoy specialty coffee. Using both simple regression and standard multiple regression analyses, it turned out that tastes, smell, mouth-feel, and satisfaction of specialty coffee had effects on coffee price. This study implies that when coffee consumers decide coffee price, they consider multiple factors to influence their overall satisfaction in multiple aspects than a single facet like taste, aroma, and mouth-feel. Practical and theoretical discussion and implications are suggested for the following studies.

This paper is concerned with the influence in the job satisfaction by the organization, the job specialty and the self-devotion in the special duty of private security. Today's society is required more intensive security in the diversity, the complexity and the uncertainty, but the public security service could not supply enough for what the society requires. In this circumstance more specialized and special trained security services are demanded from private security industry. With the concerns, this study is based on actual survey. The study is telling us that there is much relationship in job satisfaction between each element. Which means that 1) there is some different from personality, 2) there is much influence in self-devotion by job specialty, 3) there some effectiveness in job satisfaction by job specialty, 4) there is some influence in job satisfaction by self-devotion, and 5) job satisfaction is affected by job specialty and self-devotion.

Microparticle and micropolymer retention and drainage aid systems are powerful tools for paper and board making on a variety of machines. Drawbacks attributed to the current systems sometimes include; apparent high cost, production and quality problems and in some cases a negative effect on formation. The next generation multi-component organic/inorganic systems have demonstrated their ability to decouple the effects of retention and drainage and to improve the formation and print quality for the same retention and in some cases higher retention levels. It is now possible to optimize independently retention, drainage and formation effects with the same high return on investment of current microparticle systems.

본 연구는 대표적인 건설경기지표인 건설수주액의 변화가 전문건설업체의 경영성과지표에 미치는 영향을 분석하고 각 경영성과지표 사이에 관계를 파악하여 건설수주액의 변화에 따른 전문건설업체의 대응전략을 제시하기 위한 목적으로 수행되었다. 토목중심의 전문건설업체는 유동비율이 건설수주액에 큰 영향을 미치는 것으로 나타났으며, 건설수주액이 자기자본비율에 큰 영향을 주고 있어 건설수주액 자체가 기업의 안정성과 직결된다고 판단된다. 특히, 유동비율이 건설수주액에 관계가 있다는 것은 최근 시공능력평가에서 이에 대한 지표의 중요성이 강조되기 때문인 것으로 판단되며, 이에 대한 개선을 통해 수주활동을 개선할 수 있을 것으로 판단된다. 실제로 전문건설업체에서는 충분한 자산과 많은 매출액을 확보한 상태에서 부도가 나는 이른바 흑자부도가 발생하는데, 이는 기업이 단기적으로 채무에 대한 지급능력이 떨어지기 때문이며, 이러한 유동비율은 기업의 존폐가 직결된다 할 수 있다.

본 연구는 공사를 진행하는 경영형태 - 조직적 경영 및 개인적 경영형태에 따른 전문건설업체의 경영성과지표와 건설경기지표간의 상관성 분석을 통해 경영 안정화 전략을 제시하기 위한 목적으로 수행되었다. 이를 위하여 1997년부터 2010년까지의 자산규모 70억 원 이상의 전문건설업체의 건설수주액 및 경영성과지표에 대한 자료를 분석하였다. 전문건설업체조직적 경영중심의 전문건설업체는 건설수주액이 기업의 안정성에 직접적인 영향을 미치고 있어 건설수주액의 감소가 자기자본비율에 악영향을 미칠 수 있다. 그러나 총자본회전율이 자기자본에 영향을 주고 있음을 고려할 때, 건설수주액의 증가로 확보된 자기자본에 대해 매출액을 증가시킬 수 있는 자본운용계획을 수립할 필요가 있다. 개인 경영중심의 전문건설업체 역시 건설수주액의 변화에 대해 안정성 지표인 자기자본비율이 크게 영향을 받으므로 이에 대한 대응전략이 필요하나, 부채비율이 건설수주액에 영향을 미치고 있으므로 부채비율을 감소시킬 수 있는 대응전략이 필요하다.

For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

The effects of culture depth (2-10 cm) and cell density on the growth rate and biomass productivity of Chlorella sp. XQ-200419 were investigated through the use of a self-designed open circular pond photobioreactor-imitation system. With increases in culture depths from 2 to 10 cm, the growth rate decreased significantly from 1.08 /d to 0.39 /d. However, the biomass productivity only increased slightly from 8.41 to 11.22 $g/m^2/d$. The biomass productivity (11.08 $g/m^2/d$) achieved in 4 cm culture with an initial $OD_{540}$ of 0.95 was similar to that achieved in 10 cm culture with an initial $OD_{540}$ of 0.5. In addition, the duration of maximal areal productivity at a 4 cm depth was prolonged from 1 to 4 days, a finding that was also similar to that of the culture at a 10 cm depth. In both cases, the initial areal biomass densities were identical. Based on these results and previous studies, it can be concluded that the influence of culture depth and cell density on areal biomass productivity is actually due to different areal biomass densities. Under suitable conditions, there are a range of optimal biomass densities, and areal biomass productivity reaches its maximum when the biomass density is within these optimal ranges. Otherwise, biomass productivity will decrease. Therefore, a key factor for high biomass productivity is to maintain an optimal biomass density.

Using geographical indication, a type of source identification, can effectively promote local specialty agricultural products of superior quality, by identifying the specific geographic location or origin of the produce. Agricultural products can be registered using the geographical indication by describing the product's relation to its geographical origin including the reputation and quality. However, this indication has no objective standards to qualify goods as agricultural specialty products. The purpose of this study is to suggest basic criteria to define the characteristics and criteria of agricultural specialties based on a quantitative evaluation method. To propose this basic standard, we used the proportion of arable land to denote the major production areas and the location quotient (LQ) index to grasp the extent of the specialty of a product. The results show that the average LQ values of registered agricultural products, particularly apples, pears, and garlic, are 3.26, 8.01, and 2.82, respectively. This indicates that they are more specialized than produce from other areas that have not registered for a geographical indication. Low LQ values were found in some areas with registered rice geographical indications, which are also more focused on their historical reputation as the main rice producing areas. Considering the agricultural specialty of products, the recommendation is that the producing proportion should be over 1% of the national scale and over 10% of the province scale, and the LQ value should be over 2.0. This recommendation is not a requirement, but the criteria can prove to be useful in identifying a higher range of specialized agricultural products.
