이윤원,이동경,신용백 대한안전경영과학회 2002 대한안전경영과학회지 Vol.4 No.3

The use of industrial robots has been one of the most important innovations in production technology in recent years. It is true that robotic techniques, as applied to hazardous operation in industry, have reduced the risk of injury and occupational disease among workers. However, new types of occupational safety and health risks, associated with unpredictable motion patterns and erratic idle times and serious injuries and deaths have occurred due to operator misperception of these robot design and performance characteristics. This paper provides an overview of ergonomic and safety issues which are important in the design of robotic workspaces. Particularly, this study uses MORT(Management oversight and risk tree analysis)as the system's safety technique applied to robotics.

大田地域 山火跡地 天然林과 人工林의 植生構造에 關한 硏究(II) : 生長 및 群集構造 Growth and Communities Structure

李允源 中部大學校 農業開發硏究所 1993 農業開發硏究論文集 Vol.2 No.-

本 硏究는 山火跡地의 植生回復 및 效率的 管理를 爲한 基礎資料를 提供하기 爲하여, 大田地域 山火跡地를 中心으로 산불發生後 更新된 天然林과 人工林 主要 樹種의 生長 및 林分發達狀態, 環境要人의 變化와 植生과의 相互作用, 群集 構造 및 安定性, 植生遷移 등을 比較分析한 結果는 다음과 같다. : 1. 土壤이 理化學的 特性은 A層이, 그리고 斜面部位別로는 斜面下部가 가장 좋았다. 調査地別로는 산불發生後 6年이 經過한 닭재地城과 人工林 中에서는 낙엽송林이 土壤條件이 가장 좋았으며, 산불發生後 經過時間이 짧은 산홍·실전 地域과 리기다소나무林·아카시아나무林은 土壞條件이 相對的으로 下良하였다. 칼슘(Ca)은 天然林과 人工林 두 集團間에 가장 顯著한 差異를 보이는 土壤因子였으며, 산불發生後 經過時間과 相關關係가 있었다. 2. 胸高直徑과 樹高는 편백林이 가장 優秀하였고 그 다음으로 胸高直徑은 낙엽송林이, 樹高는 상수리나무林이 優秀하였다. 斜面別 生長差는 天然林이 적었고 리기다소나무林·아카시아나무林은 斜面 上·下部의 生長差가 가장 큰 것으로 나타났으며, 土壤條件과 相關關係가 있었다. 3. Cluster Analysis 分析 結果, 本 山火地域는 상수리나무-신갈나무集團, 떡갈나무-신갈나무集圍, 그리고 人工林集團으로 分類되었다. 4. PCA-COA Ordination 分析 結果, 本 山火跡地의 群集의 Ordination은 낙엽송林, 편백林, 기타 地域으로 配列되었고 樹鍾의 Ordination은 이들 地域의 構造種으로 이루어졌다. 5. Simple Discriminant Analysis 및 Linear Regerssion 分析 結果, 土壞因子 가운데 置換性 陽이온 含量이 Classitication과 Ordination에 의한 群集 및 樹鍾의 分類와 配列에 가장 른 寄與率(percent contribution)을 보인 것으로 나타났다. 6. 植生遷移는 天然林의 경우 喬木上層은 상수리나무·떡갈나무에서 신갈나무로, 喬木下層은 계속 신갈나무와 졸참나무로, 그리고 喬木層은 싸리나무에서 진달래로 遷移가 進行될 것으로 推定되었다. 7. 人工林의 喬木上層-喬木下層-喬木遷移는 낙엽송林에서는 낙엽송-찔레나무·말발도리에서 낙엽송-팽나무-진달래로, 리기다소나무林에서는 리기다소나무-상수리나무-산행도나무·싸리나무에서 리기다소나무-상수리나무·신갈나무-때죽나무로, 편백林에서는 편백-작살나무에서 편백-비목나무·생강나무로, 그리고 아카시나무林에서는 아카시나무·떡갈나무-아카시나무·졸참나무-아카시 나무·졸참나무가 그대로 維持될 것으로 推定되었다. 8. 本 山火跡地 人工林 중 리기다소나무林과 아카시나무林은 이미 참나무類가 喬木下層과 喬木層을 强하게 占하고 있어 群集의 持續이 不安定하고 土壤環境의 改善에도 매우 不利한 것으로 나타났으며, 낙엽송林과 편백林은 群集의 維持도 可能하고 生長도 좋지만 各各 植生 覺亂, 後續林 不在로 因해서 天然林의 維持보다 經濟的으로나 生態學的 不利할 것으로 判斷되었다. This study was to provide the fundamental data for vegetation recovery and efficient management of fire-burned forest area. For the purpose of this study, natural and artifical forests reproduced after fire burning were selected, including 7 sites of natural forests consisted of various fire-burned dates and 4 sites of artificial forests 4 dominant tree species, Larix leptolepis, Pinus rigida, Chamaecyparis oblusa, Robinia pseudoacacia, and were investigated about growth and stand development of major dominant species, fluctuations of environmental factors and its interactions to vegetation, the structure and stability of communities, and successional trends. Obtained results are as follows: 1. Soil chemo-physical properties showed the more higher value soil A-layer and the lower part of slopes. Of all the area, Dakjae area that 6 years has past after the fire and Lariz leptolepis forest among artificial forests had the best soil conditions. But Siljun and Sanheung area that 3-4 years have past after the fire and Pinus rigida forest and Roninia pseudoacasia forest were under the most worst soil conditions. Caiciuln (Ca) showed the most remarkable difference among soil factors between natural and artificial forests. 2. D. B.H. and tree height showed the most high value in chamaecuparis obtusa forest, in turn d.b.h in Latix leplolcpis forest, and tree height in Quercus acutissima forest. Variance of growth with respect to various slopes were little in natural forest, but were high in Pinus rigida forest and Robinia pseudoacasia forest, having a relationships with soil conditions 3. As a result of Cluster Analysis this study area were divided into three groups, Quercus acutissima-Quercus mongolical community, Quercus dentata-Quercus mongolica community, and the artificial forest conlmunity 4. As results of PCA & COA Ordination Analysis, communities of the study area were divided into Larix leplolepis forest, Chamaecyparis obtusa forest, and other forests, and species ordination into species groups consist of those communities 5. As results of Simple Discriminant Analysis and Lincar Regerssion, contents of exchageable cations showed tile most high percent contribution to clustering and ordinating of communities and species by classification and ordination among soil factors 6. The successional trends of natural forests were expected to be progressed from Quercus acutissima·Quercus dentata to Quercus mongolica in canopy layer, and to Quercus mongolica in understory layer, and from Lespedeza bicolor to Rhododendron mucronulatum in shrub layer. 7. The successional trends of each conopy-subtree-shrub layer of artifical forests were expected to be progressed as follows ; From Larix leptolepis-Larix leptolepis- Rosa multiflora·Deulzia parviflora to Larix leptolepis-Cellissinensis-Rhododendron mucronulatum in Larix leptolepis forest, from Pinus rigida-Quercus acutissima-Vaccinium Koreanum·Lespedeza bicolor to Pinus rigida-Quercus acutissima·Quercus mongomaecyparis obtusa-Lindera erythrocarpa·Lindera obtusiloba in Chamaecyparis obtusa forest, and to Robinia pseudoacasia·Quercus dentata-Robinia pseudoacasia·Quercus serrata without vegetational changes for the time being in Robinia pseudoacasia forest 8. For artificial forests, Pinus rigida forest and Robinia pseudoacasia forest showed pool soil conditions and instable community structure due to the strong domination of Quercus spp., and Larix leptolepis forest and Chamaecyparis obtusa forest vegetational disturbance and absence of succeeding forest, repectively, and therefore artificial forests are insuitable for recovery and management of the fire-burned forest area than natural forests, from economic and ecological view.

Current business accounting related rules induding Korea financial accounting standards, commercial law are retaining unique reason for being and own characteristics respectively. Come from by this, There is conflicting from several parts between commercial law and financial accounting standards. Therefore, there are serious confusion and social waste in staff in charge' s position such as companies and competent authorities which must apply this. Purposes of this study to exarnine relation and reason of disharmony between both and involved problem in each rule and to present revision direction and repletion direction of individual accounting related rules, and reasonable and realistic re-thesis alternatives between commercial law and financial accounting standards. This study adopted the methodology of deductive literature research which examine prior research and foreign cases and research contents of related laws. Together, this study aims to new groping in the up- to- date revision tendency after reflected Academic symposium entitled ’Relation lighting among accounting related rules in global world' that Korea Accounting Association, Korea Academic Society of Taxation and Korea Commercial Law Association holds jointly on January, 2005 and amended bill of commercial law which legislation advanced notice in October 2006 via public hearing of July, 2006 on October. Difference between commercial law and financial accounting standards are caused from lacks of the systematic consistency basically. Substantial alternatives to solve these problems may consider as follows: First, Japan style alternative that keeps current commercial law and structure of regulation on external audit of corporations and gropes agreement with financial accounting standards. secondly, alternative that revise the system of calculation regulation in commercial law sharply and delegate business accounting principles in financial accounting standards by commercial law that is not regulation on external audit of corporations. When remodels the system of accounting related rules newly which laying stress on commercial law, There needs to prescribe basic and essential items about business accounting principles to commercial law and to ready detail and technological items which is involved with accounting processing to business accounting standards by private- sector organization. Furthermore, It needs to the legal ground about establishment of private- sector organization to commercial law. And need to erase the legal ground of financial accounting standards of regulation on external audit of corporations and move by commercial law because company account standard doesn’t have logical basis or reason that must be based on external audit of corporations, and there is no justice that financial accounting standards should be applied to company which assets scale is more than seven billion It is difficult to apply to financial accounting standards in small and medium-sized entities which include human company and private merchant, and It equips global convergence in business exactly to general company and small and medium-sized entities in situation that financial accounting standards are globalized and complexed. Therefore, It is necessary to discussion multiple tier of account standard and enactment of medium and small enterprises accounting standards. Hereafter, It must include institutional basic regulation to commercial law in order to enact IFRS, Stratification of GAAP, and separate accounting standards for small and medium-sized entities.

본 연구에서는 중소기업을 대상으로 경영혁신기법이 기업성과에 미치는 영향에 대하여 정보시스템성숙도의 조절효과와 매개효과를 실증적으로 분석하였다. 연구결과에 따르면 정보시스템성숙도는 경영혁신기법의 활용정도와 기업성과의 관계에 대하여 조절효과뿐만 아니라 매개효과를 나타내는 것으로 분석되었다. 정보시스템성숙도의 조절효과는 정보시스템이 경영혁신기법활용정도와의 상호작용을 통하여 기업성과에 차별적인 영향을 미치며, 정보시스템성숙도가 높을 경우에 기업성과는 더욱 크게 나타난다는 것을 의미한다. 정보시스템성숙도의 매개효과는 경영혁신기법의 활용정도가 정보시스템을 통하여 기업성과에 추가적인 정의 영향을 미친다는 것을 나타낸다. 기업의 정보시스템은 경영혁신기법의 주요성공요인으로서 기업의 업무체계와 조직구조의 변화를 반영한다. 따라서 정보시스템성숙도의 조절효과와 매개효과는 경영혁신기법이 기업성과에 미치는 직접적인 영향과 함께 정보시스템을 통한 기업성과의 개선과정을 이해하는 중요한 수단으로 작용한다. This study analyzes empirically the impact of information system capacity(ISC) on the relationship between management innovation technique(MIT) and business performance of small and medium size companies. According to the results of study, ISC gives both moderating and mediating effects on the relationship between MIT usage and performance. The moderating effect of ISC suggests that the interaction of an information system and MIT gives differential influence on the business performance and the performance increases with higher ICS. The mediating effect of ISC shows that MIT usage gives additional positive influence on the business performance through the information system. The information system is a key success factors of MIT and also responds changes of the firm's business and organization structure. Therefore, moderating and mediating effects of ISC become important tools of understanding direct influence of MIT on business performance and also the process of performance improvement through the information system.
