Korea’s R&D investment has significantly increased in recent years and the quantitative outputs such as number of papers and patents have also increased with the investment. However, the quality of R&D outputs has not been fully addressed. In particular, quality of technical performance, such as the quality of patents, has attracted little attention. In this paper, a Data Envelopment Analysis (DEA) method was used to construct models for efficiency analysis of R&D investment, focused on quality of technical performance. Indices were proposed to analyze the quantitative and qualitative efficiencies of R&D investment. In order to effectively analyze R&D efficiencies, the measurement units of the input and output variables were standardized. Based on cases of livestock quarantine R&D projects of Korea, the quantitative and qualitative efficiencies of national R&D projects were analyzed and factors that would influence R&D efficiencies were identified. This paper suggests that both quantitative and qualitative efficiencies should be considered when measuring R&D efficiency. Also, it is recommended to carefully consider the characteristics of R&D projects during project selection stage.

고분자물질의 사용으로 인한 건축 재료의 다변화에 따라 화재 시 발생되는 연소가스 또한 다양해지고 있다. 그중 HBr은 NES 713과 BS 6853, FTP Code Part 2에서 연소 가스의 독성 평가 시 측정되는 독성가스이다. 특히 산업안전물질보건자료(MSDS)에서는 HBr가스를 흡입할 경우 화상을 일으키며 호흡부전, 두통 등을 유발시킬 수 있고 50ppm의 HBr가스에 노출된 사람은 생명과 건강에 즉시 영향을 받을 수 있는 매우 유독한 연소가스이다. 본 논문에서는 HBr 표준가스에 노출된 동물의 운동성 측정실험인 가스유해성 시험 및 HBr가스에 노출된 마우스의 생물학적 검사 결과를 비교 분석하여 HBr의 연소 독성에 관한 연구를 수행하였다.

In this paper, quantitative and systematic procedures for establishing Key Performance Indicators (KPI’s) of R&D departments are presented. The proposed methodology is composed of 4 steps : 1) identification of critical success factors, 2) identification of potential KPI’s, 3) determination of KPI’s and 4) monitoring and execution. A Strategy Map has been presented to better align KPI’s with a company’s competitive strategies. Also, Analytical Hierarchy Planning (AHP) is used to determine weights of KPI’s and Data Envelopment Analysis (DEA) is used to analyze the effectiveness of R&D departments. To demonstrate its validity of the proposed method, it has been applied to the R&D divisions of a semiconductor company.

우리나라에서 건축물 내장재의 화재안전성능은 국토해양부 고시 제2011-39호에 의한 평가방법에 의해 불연성시험(KS F ISO 1182), 열방출률시험(KS F ISO 5660) 및 가스유해성시험(KSF 2271)을 실시하여 그 결과로서 분류하도록 되어 있다. 그 중 연기 및 연소독성가스에 대한 시험인 가스 유해성 시험은, 건축재료 및 내장재의 연소시 발생하는 가스의 유해성을 마우스의 평균 행동정지시간으로 측정하는 방법으로 사용하여 왔다. 이 중 연소 독성가스 4종(HCl, HF, HCN, SO2) 흡입독성시험방법의 확립을 위하여 ICR계 mouse와 전신흡입노출장치를 이용하여, 독성가스 노출 및 병리검사를 수행하였다. 그 결과 호흡기관지와 가까운 폐포에서 대식세포(Macrophage)의 침윤을 유발하는 것으로 나타났고, 4종의 물질에 대한 조직의 병리검사로 전체적으로 충혈과 울혈은 확인되었다. 조직 중 폐와 신장에서 조직손상이 심하였고, 물질로는 HCN이 가장 많은 병리소견을 보였다.

This study was carried out to observe the impacts of a mouse's inhalation of toxic gas SO2 generated from combustion on its organs by different concentrations. As for research methods: First, after concentrations of SO2 generation from combustion had been set to three: low (10.4 ppm), middle (24.9 ppm) and high (122 ppm) through Gas Toxicity Testing Method (KS F 2271) and SO2 combustion gas was exposed to eight mice in each concentration. Five mice that were able to move based on LD50, a criterion, which sets the down time of a mouse's average behaviors to over 9 minutes, were randomly selected in each concentration, and they were set up as the subjects of the study on toxicity bio-markers. Second, tissues were taken from heart, liver, lungs, spleen and the thymus gland of the mice selected in each concentration and a pathological examination of them was carried out. As a result, microvascular congestion appeared in the heart, and cell necrosis, cortex congestion and tubule medulla congestion, etc. in each concentration were observed in addition to vascular congestion in liver, lungs, spleen and the thymus gland. Also, it was found that the higher the concentrations of SO2 exposure is, the greater, the changes in the organs get. Through this study, SO2 of various toxic gases generated from fire turned out to affect the tissues of each organ of a mouse, it is expected that the toxic gases may greatly affect human body in case of actual fire, and this study is evaluated as having a significance as a basic data on inhalation toxicity assessment of toxic substances generated in combustion.

It is analysed the efficiency of the Korean IT industry using CCR and BCC models of the DEA(Data Envelopment Analysis) method in this study. In this study, the Korean IT industry is classified into 7 groups which are Displays, Digital Contents, Wireless Communication Devices, Telecommunication Services, Semi-Conducts, Broadcasting Services and Computer Services that the efficiency of each groups is analysed contrastively. And it is considered to find a way to improve the efficiency of inefficient companies using the slack variable analysis. Also the Super DEA is used to find the relative rank among companies that their efficiency is 100% and the change of the Korean IT efficiency is measured by the Time Series Analysis from 2005 to 2007 for 3years as well.

As today's business environment becomes more globalized and distributed, the importance of collaboration is rapidly increasing. This paper presents a systematic approach to collaboration strategy planning. The framework suggests a Collaborative Process Map need to be identified. Then, Collaboration Maturity of each area is evaluated. Based on the Collaborative Process Map and Collaboration Maturity Evaluation, Collaboration Execution Plans are established. A case study of semiconductor industry is also provided.

This study proposes a new approach which combines Data Envelopment Analysis (DEA) and the Analytic Hierarchy Process (AHP) techniques to effectively evaluate Decision Making Units (DMUs). While DEA evaluates a quantitative data set, employs linear programming to obtain input and output weights and ranks the performance of DMUs, AHP evaluates the qualitative data retrieved from expert opinions and other managerial information in specifying weights. The objective of this research is to design a decision support process for managers to incorporate positive aspects of DEA's absolute numerical evaluations and AHP's human preference structure values. It is believed that a pragmatic manager will be more receptive to the results that include subjective opinions incorporated into the evaluation of the efficiency of each DMU efficiency when the AHP and DEA are combined simultaneously. The WPDEA method provides better discrimination than the DEA method by reducing the number of efficient units.

In order to utilize waste wood chip for pavement, a polyurethane resin that is both eco-friendly and suitable for bindingwood chip was developed as the binder, and workability was examined through laboratory experiment for characteristicsof waste wood chip mixture using the polyurethane resin and through test pavement on the field. The new resin was aVOC reduction type free from plasticizer and solvent classified as endocrine-disrupting chemicals and environmentalhazardous substances, and NCO equivalents were set at 8, 9, 10 and 11% by modifying the polyisocyanate-polyol ratio.Laboratory experiment showed that polyurethane resin with NCO equivalent of 9% and 10% had excellent characteristicsas binder for waste wood chip. In the field experiment applying waste wood chip and polyurethane resin in the massratio of 1:0.8, tensile strength of the pavement system was about 30% higher than that using polyurethane resin currentlybeing sold, and permeability coefficient and elasticity thereof were the same as that using the resin currently being sold.Also, examination of compaction methods for waste wood chip pavement system showed that non-heating hand rollerand compactor had the problem of the “waste wood chip - resin mixture” sticking to the roller during the compaction but that heating hand roller had excellent workability and could achieve good planation surface relatively easily.

목재칩과 우레탄 수지를 결합한 혼합물을 보도포장의 표층재료로서 사용하였을 때, 기상조건에 따른 물성 변화를 알아보기 위한 실험을 실시하였다. 시험체는 다짐기구의 종류에 따라 다짐횟수 및 가압시간을 변화시켜 폭 410mm, 길이 670mm, 두께 40mm의 크기로 제작하였으며, 7일 양생 후 단위용적질량을 측정한 다음 폭 30mm의 크기로 절단하여 인장강도 시험을 실시하였다. 기상조건에 따른 물성 변화를 알아보기 위한 실험은 강우 환경과 해수 환경에서의 실험, 동결융해실험 및 내후성 실험으로 구분하여 실시하였다. 목재칩과 우레탄 수지를 결합한 혼합물에 대한 실험결과, 인장강도는 강우 환경에서 상당한 감소를 나타냈으나 이러한 강도 저하는 해수 환경 및 동결융해 시에 더욱 심화되지는 않는 것으로 나타났다. 또한 제논 아크에 노출시킨 경우 시험체의 인장강도가 변화하였는데 이는 목재칩과 우레탄 수지의 혼합물이 햇빛에 의해 다소 열화될 수 있음을 나타낸 결과로 판단된다.
