Using response surface methodology to assess the effects of iron and spent mushroom substrate on arsenic phytotoxicity in lettuce (Lactuca sativa L.)

Koo, N.,Jo, H.J.,Lee, S.H.,Kim, J.G. Elsevier Scientific Pub. Co 2011 Journal of hazardous materials Vol.192 No.1

The effects of iron (Fe) and spent mushroom substrate (SMS) arsenic (As) phytotoxicity towards lettuce in artificial soils were investigated to separate the adverse soil parameters relating to As toxicity using a response surface methodology. SMS induced the root elongation of lettuce in both control and As-treated soils. However, in phytotoxicity test using a median effective concentration (EC<SUB>50</SUB>) of As, Fe and the interaction between both parameters (Fe*SMS) significantly affected EC<SUB>50</SUB>, which explained 71% and 23% of the response, respectively. The refined model was as follows: EC<SUB>50</SUB> of As (mgkg<SUP>-1</SUP>)=10.99+60.03xFe-10.50xFe*SMS. The results confirmed that the soil parameters relating to the As mobility in soils were important factors affecting its toxicity. In conclusion, Fe significantly reduced the As phytotoxicity. However, although SMS enhanced the root elongation, SMS in As-treated soils decreased EC<SUB>50</SUB> of As on the root growth via its interaction with Fe. Despite the limitations of the artificial soils and range of parameters studied, the application of this statistical tool can be considered a powerful and efficient technique for interpretation and prediction of the complicated results caused by the interactions between many factors within the soil environments.

PPM에 의한 組織戰略計劃

咸根培 한국항공대학교 1982 論文集 Vol.20 No.-

最高經營者의 主要課業의 하나는 企業의 Portfolio plan을 立案하는 것이다. 企業은 어느 時點에 있어서나 部課, 製品系列, 製品, 商標와 같이 Portfolio로 形成되어 있다. 이것은 營利的인 社會뿐 아니라 非營利的인 組織도 마찬가지이다. 과거의 最高成長 時期에는 대부분의 조직이 每年 誇大한 豫算을 割當함으로써 그들의 事業單位의 成長을 꾀하였던 것이다. 그리하여 賣出額의 增大로 利益目標를 達成하는 것이었다. 그러나 賣出額은 深刻한 減少現象을 가져오고, 在庫積滯라는 두통꺼리 제품마저 생기게 되었다. 最近에 이르러 運營資金의 壓迫과 販賣機會의 蹉跌로 企業組織은 더욱 選擇的으로 움직이지 않으면 안되게 되었다. 그리하여 最高經營者의 任務는 어느 事業을 일으키고 維持하며, 어느 事業을 減産하고 閉鎖하느냐를 意思決定하는 것이다. 그리하여 會社의 主要目標는 貧弱한 事業은 갈아치우고, 展望이 좋고 將來가 約束되는 새로운 事業을 追加하므로서 會社의 Portfolio를 계속 新鮮한 것으로 간직하는 것이다. 이러한 目標를 達成하기 위해 經營管理者는 우선 會社의 戰略事業單位(SUB)를 가려내서 識別해야 한다. 戰略事業單位는 기업이 놓여진 환경 여하에 달려 있지만 會社 部課의 하나나 그 이상이 될 수도 있고, 府署내內의 製品系列이 될 수도 있고, 때로는 單一制品이 될 수도 있다. 다음 段階는 經營管理者가 資源配定에 있어 最大의 效用價値가 示顯되도록 모든 戰略事業單位를 分類해야 한다. 分類方法에 있어서 널리 알려진 것으로서 Boston Consulting Group와 General Electric 方法이 있다. Portfolio 企劃을 立案하는 데 있어 會社의 Marketing 擔當管理者는 新製品開發을 위한 Idea의 제시와 會社의 Portfolio에서 除去되는 代替事業의 案出이라는 무거운 짐을 두 어깨에 짊어지게 된다. 健全하고 새로운 Idea를 착상하고 成功的인 代替事業을 開發하기 위해서는 戰略的인 新製品開發節次라는 完全無缺한 뒷받침이 있어야 한다. 따라서 本稿는 PPM이라는 新製品開發管理理論이다. One of the major task of top management is the shaping of a business protfolio plan. At any point in time, a company consists of a portfolio of businesses(divisions, product line, products, brands). This is true for nonprofit organizations as well as industrial companies. In the past, most organizations encouraged all their business units to grow by giving all of them a larger budget each year. All were held to increased sales and profit goals. The exceptions were seriously decling or troubled products. In recent years, organizations have moved to more selectivity because cash is scare and opportunities differ greatly. Organizations now view themselves as managing a portfolio of businesses, and top management's job is to decide which businesses to build, maintain, phase down, and phase out. This a major company objective is to keep refreshing the company's portfolio of business by flushing out poor ones and adding promising new ones. to carry out this objectives, management first has to identfy the strategic business units(SBUs) marking up the company. An SBU can, depending of the circumstances, be one or more company divisions, a product line within a division, or sometimes a single product. The next step calls for management to classify all of th SBUs in a way that would feveal their resouce-allocation merit. The two best-known classification schemes are those of the Boston Consulting Croup and General Electric. The other implification of portfolio planning is that company markders bear the main burden for coming up with new ideas for products and businesses to replace those that are being eliminated from the company's portfolio. Finding sound new ideal and developing them successfully calls for a well-worked-out theory of the strategic product planning process.

Jonathan Swift 小考 : 그의 厭世思想

李君喆 연세대학교 인문과학연구소 1963 人文科學 Vol.10 No.-

The eighteenth century in England was an age of light and sweet reason. Politically, economically and socially, England expected a bright future. Affirmation of life and a sanguine sense of progress that prevailed in contemporary minds seemed to be an unlikely setting for a "heretic" of Swift's hubris. More so when society favored writers as at no other time. Swift seems to have been a born rebel-his being an orphan apart-who grew up into a satirist with a glummy outlook, tilting not only at society but at the whole scheme of things.

본 硏究는 韓 ? 경 ? 의 제2의 도약을 위하여, 必要한 生産性이란 問題를 賃金과의 관계하에서 硏究한 것으로서, 국民경 ? 적인 巨 ? 的涎元보다는 企業單位의 微 ? 的 立場에서 生産性과 賃金을 결부시킨 연구이다. 理論的 展開에서, 生産性中心賃金은, 賃金의 決定基準관점에서 볼 때, 限界生産力에 그 기준이 있는 석으로 把握, 이를 中心으로 제반관련문헌연구를 했으며, 賃金과의 觀察에서는, 生産性指標로는 物的生産보다는 附加價値生産性指標가 보다 合理的임을 數理的으로 밝혔다. 끝으로 모델의 開發은 絶 ?的인 制度보다는 各 企業 및 産業의 水準에 맞는 相 ?的 制度가 보다 요구되므로, 이를 위한 알고리즘 및 各 段階에서의 이의 解決을 위한 著 方法들을 기술하였다. This paper aims at the research of connection of wage with productivity which is the major factor for the 2nd Korea's economic take-off, based not on the macro dimension of national economy but on the micro dimension of corporation. In the main subject, because the wage system based on the productivity is focused on the conception of the Marginal Productivity Theory(M. P. T. ), literature research is done with the concentration of M. P. T. . In addition to this, it is proved mathematically that the productivity of added value is of much use than that of product-volume, for the reasonable wage system. Conclusively, this paper described the algorithism of approach for the development of wage system based on the productivity, and the various methods for each stage in algorithism.

This study aims at investigating the difference upon RER caused by external load. The results are as follows. 1. RER(Male) 1) During treadmill exercise, All weights has droppped little by little for 3.50 minutes, but they increase little by little after 3.50 minutes. 2) In the excess of RER "1.0", BW records at 10 minutes, and the HW (11.50 min), NW(12.50 min), and LW(13.50min). 3) The R² of Regression line (above 49.689) is comparatively rational and very valid is significance level (p<0.05) as well. 4) In normal distribution of Residuals scatterplot, MNW nd MLW are normal but MHW and MBW are almost normal. However, in independent variable, MHW and MLW are normal but the other weights are almost normal or subnormal. 2. RER(Female) 1) During treadmill exercise, All weights has little by little dropped for 4 minutes, but after 4 minutes, they are on the increase little by little. 2) In the excess of RER "1.0", BW is the fasted by the time of 8.50 minutes and then HW(10min), LW(10min), NW(12min). 3) The R² of Regression line (below 43.438) is low but valid in significance level (p<0.05) as well. 4) In normal distribution of Residuals scatterplot, FNW and FBW are normal but FHW and FLW are almost normal. However, in independent variable, FBW is normal but the other weights are almost normal.
