본 실험은 항생제 $BMD^(R)$ premix(Bacitracin methylene disalicylate), 유기산 복합제인 $Lactacid^(R)$((주) 은진인터내셔날) 그리고 essential oil 제품인 $Immunocin^(R)$((주) 은진인터내셔날) 이 육계에 미치는 영향을 비교 평가하기 위하여 생산성, 영양소 이용율, 혈액 성상, ND titer, IgG, 그리고 장내 미생물 균총 등을 조사하기 위해 실시하였다. 사양 시험은 육계 ($Ross^(R)$종) 1,000수 (암 수 각각 500수)를 공시하여 4처리 5반복, 반복당 암 수 동수로 50수씩을 floor pen(가로: 2.0m, 세로: 2.4m) 에 완전임의 배치하였다. 사양시험 기간은 35일, 시험 기간 동안 물과 사료를 자유 채식시켰고 24시간 점등하였다. 시험구는 대조구, $BMD^(R)$ premix(Bacitracin methylene disalicylate 2.5%) 0.1 % 첨가구, $Lactacid^(R)$ 0.5% 첨가구, 그리고 $Immunocin^(R)$ 0.1% 첨가구등 4첨가구를 두었다. 생산성에서 essential oil 복합제 $Immunocin^(R)$ 0.1% 첨가구가 $BMD^(R)$ 25ppm 첨가한 항생제구와 동일한 수준의 생산성 개선 효과를 보였는데 (P<0.05) 특히 사료 요구율이 유의하게 향상되었다(P<0.05). 그러나 유기산 복합제인 $Lactacid^(R)$ 0.5% 첨가구는 항생제구보다 생산성 개선 효과가 없었다. IgG 농도는 $Immunocin^(R)$구가 첨가구들 중에서 가장 높았으며(P<0.05) 혈액의 leukocytes 와 stress index는 $Immunocin^(R)$ 첨가구가 낮은 경향을 나타냈다. 장내 미생물의 Cl. perfringens 수는 첨가구간에는 유의차가 없었으며 E. coli 수는 항생제구와 $Immunocin^(R)$ 구가 가장 적었다(P<0.05). 영양소 이용 율에 있어서 조단백질은 $Lactacid^(R)$ 구와 $Immunocin^(R)$ 구 높았다(P< 0.05). NFE 이용율은 생산성 개선 효과는 없었으나 $Lactacid^(R)$ 구가 가장 높았다(P<0.05). 결론적으로 essential oil 제제인 $Immunocin^(R)$을 육계 사료의 첨가제로 사용시 항생제와 같은 수준의 생산성 개선 효과를 보였으나 유기산제제인 $Lactacid^(R)$는 대조구와 차이가 없었다.

Quality management has become an pervasive philosophy in most sectors of business. Specific movements such as statistical quality control, quality circle, total quality management, and quality management system have become embedded in business organizations. Only the companies with competitive edge can survive in the competition in global market. KSA(Korean Standards Association) established in 1962 has launched all kinds of quality education, quality standard certification service for business, and KNQA(Korean National Quality Award) system. This article considers quality competitiveness excellent company award among KNQA. We performed a statistical analysis of audit data for quality competitiveness excellent company for three years, from 2015 to 2017. By using ANOVA and two sample t-tests, the average scores of 13 evaluation fields were significantly different depending on company size and type. We proposed ways to improve the current hall of fame system. We discovered that the average scores of 13 evaluation fields in the audit data according to years and hall of fame status were not significantly different. We also showed linear relationships among 13 evaluation fields by correlation analysis and obtained an estimated linear regression equation : Business Performance, which is a comprehensive index, as a dependent variable was significantly related to Customer Focus and Product Liability as regressor variables among 13 evaluation fields by regression analysis.

본 연구는 수돗물과 SWRO 생산수의 수질 특성을 분석하여 SWRO 생산수가 지닌 강한 부식성을 확인하였으며, 이를 근거로 해수담수화 시설의 유지관리 및 부식제어를 목표로 진행되었다. 연구 초기 과정에서는 철 시편(mild steel coupon)에 대한 회분식 실험(Batch test)과 전기화학 실험을 통해 수돗물과 SWRO 생산수의 부식성을 비교하였다. SWRO 생산수의 부식성 제어를 위한 수단으로써 액상소석회(liquid lime, $Ca(OH)_2$)와 이산화탄소(Carbon Dioxide, $CO_2$)를 주입하는 방법과 액상소석회와 인산염계 부식억제제(Phosphate Corrosion Inhibitor, $P_2O_5$)의 조합에 이산화탄소를 주입하는 두 가지 방법을 비교하였다. 실험을 통한 각 수질의 평가는 부식성 평가 지수인 LSI(Langelier Saturation Index)를 통해 비교하였고 그 결과를 통해 액상소석회와 인산염계 부식억제제의 최적 주입량을 선정하여 모의배관 실험(Loop system test)에 적용하였다. 모의배관 운전 평가 후 장착된 금속배관(steel pipe)은 내부의 스케일에 대한 기기분석(SEM, EDX, XRD) 평가를 수행하여 형성물의 주성분과 산화상 및 원소 함류량을 비교 할 수 있었다. 실험 결과, SWRO 생산수에 부식제어기술을 적용하지 않은 대조군과 비교하여 적정량의 단일 액상소석회를 주입한 경우 평균 97.4%의 높은 부식억제 효과를 나타내었고, 액상소석회 와 부식억제제 조합이 주입된 경우 평균 90.9%의 부식억제 효과를 나타냈다. 모의배관 실험 과정 중 금속배관 내부에 형성된 스케일은 대조군의 경우 주로 철 산화물인 반면, 실험군의 경우 탄산칼슘($CaCO_3$) 피막이 형성되어 부식방지에 효과적임을 확인하였다.

기존의 연구논문들에서는 1975년부터 1992년 사이의 OECD 국가들에서 집권정부별 국민들이 느끼는 행복감을 알아보기 위한 분석들이 주로 이루어졌다. 이러한 행복감을 알아보는 데에는 특히 인플레이션율과 실업률이 주요 변수로 활용되고 있다. 각국별로 살펴볼 때, 진보정부의 경우에 있어서는 실업률에 더 주안점을 두는 반면에 보수정부 는 인플레이션율에 더 민감하게 대처함을 알 수 있었다. 이러한 점들을 살펴보면, OECD 국가들에서 빈곤층은 진보정부를 선호하고 상대적으로 소득수준에서 상위계층 은 보수정부를 선호할 것으로 추정된다. 이 논문에서는 한국의 경우 시계열 관계상 진 보정부와 보수정부로 나누지 않고 행복감에 대하여 소비자심리지수를 대용변수로 사 용하였을 경우 경기회복에 따른 산업생산 증가와 이를 위한 정부지출이 중요한 변수 임을 알 수 있었다.

This paper examines short-run and long-run dynamic relationships between selected macroeconomic variables and stock prices in the Korea Stock Exchange. The data is restricted to the period for which monthly data are available from January 1986 to October 2016 (370 observations) retrieved from the Economic Statistics System database sponsored by the Bank of Korea. The study employs unit root test, cointegration test, vector error correction estimates, impulse response test, and structural break test. The results of the Johansen cointegration test indicate at least three cointegrating equations exist at the 0.05 level in the model, confirming that there is a long-run equilibrium relationship between stock prices and macroeconomic variables in Korea. The results of vector error correction model (VECM) estimates indicate that money supply and short-term interest rate are not related to stock prices in the short-run. However, exchange rate is positively related to stock prices while the industrial production index and inflation are negatively related to stock prices in the short-run. Furthermore, the VECM estimates indicate that the external shock, such as regional and global financial crisis shocks, neither affects changes in the endogenous variables nor causes instability in the cointegrating vector. This study finds that the endogenous variables are determined by their own dynamics in the model.

1. The purpose of this study is to provide a series of statistical "bench marks" from which one can begin to think systematically about the required development of the Korean food and fertilizer needs over the next quarter-century. 2. The Korean population has been estimated by the characteristics of the population and its social and political situations today. Because fertility and mortality rates are relatively stable and are under control of politics concerned, the estimation rates were established with 1.6% over 1975-1980, 1.3% over 1981-1990, and 1.0% over 1991-2000. 3. Annual per capita absorption of milled rice has fluctuated rather closely around 140kg, since 1968, with no evidence of declining trend. Per capita absorption of barley and wheat around 120 kg, and legumes around 10.6kg, However because the case of wheat and corn productions are rather difficult the self-sufficiency in the future, the rice is considered to be accelerate its yield growth surplus the level of self-sufficiency to export. 4. The fertilizer demand in each element has been calculated by mechanical multiplication of "the recommend index of fetilizer application" to yield a unit production over the need of national food supply by crop year. 5. As a results refer to Table (8), the estimated quantities of total fertilizer demand to meet the national food supply of the years of 1974, 1980, 1985, 1.990, 1995, and 2000 are reached around 871500, 1138150, 1375480, 1515030, 1652090 and 1799850 metric tons in each year.

A management planning is an index to accomplish the goal of business enterprise and a managing guide of the top manager. It is a top manager's authority with he gives directions at the beginning of the budget year and has something to do with a responsible accounting. If we correlate this management planning with an area of accounting, we can subdivide it into followings; production and marketing schedule, demand-supply program of raw material, demand-supply program of the personnel and lobor cost program, facility investment program, balance fund program, profit and loss, and financial position program. I think, in the field of accounting for the sake of the management planning, there are motivation accounting, responsible accounting, divisional system accounting, evaluating accounting and so on. A management planning should be accomplishe and as it is accomplished, a business is going to be grown up and developed. Especially, it must be set up on the ground of the long-term strategies. When the accomplishment through the management planning, which is a social responibility that all the business enterprise are seeking after, is attained, it makes the development of business possible and we cannot dent that it is closely connected with the national economic development.

In this paper, an environmental assessment was carried out on the whole process of industrial business activities to establish a basic plan for climate change mitigation and energy independency. The whole process was divided into each discharge process in terms of water, air, solid waste, green house gases and refractory organic compounds. The flowcharts and basic unit of process were analysed for three years (2008-2010), being utilized as basic information for the life cycle assessment. It was found that the unit loading for the whole process significantly depends on changes in the operation rate change and highly concentrated wastewater inflow. About 35% of solid waste production was reduced by improving the incineration method with co-combustion in coal boiler, generating about 57% of electricity used for the whole process, and consequently reducing the energy costs. As the eco-efficiency index was found to be more than 1, compared to the previous years, it can be said that improvement in general has taken place.
