  • Evaluation methods are employed in environmental impact assessment to choose between different project site, to determine the required measures to compensate impact and to decide whether the environmental impacts are more important than the social or economic effects of a project. The main obstacles that restrict use of quantitative evaluation method are a Lack of knowledge about the environmental effects (e.g. if impacts on wildlife or landscape amenities are predicted) and the relative importance of economic and social issues compared with nature conservation stability of ecosystem or landscape beauty. In Germany, the most common method for site planning is the "ecological risk analysis". It is a kind of multi-criteria-decision-method based on quantitative and qualitative description and ordinal ranking. The various kinds of "ecological balancing methods" that are more recently developed (within the last decade) to quantify the required amount for compensatory measures instead often use cardinal figures to express the value of ecosystems, the intensity of impacts, the need for additional measures to compensate for long recuperative periods when restoring ecosystems and so on. There are still only a view attempts to quantify decisions between environmental and socio-economic issues. Multicriteria-analysis as well as cost-benifit-analysis was used. Some new approaches which are still in a preliminary status are based on contingent valuation and on calculations for compensatory payments (instead of compensatory measures).

  • Feeding is an important aspect of insect nutrition which in turn supports growth, development, reproduction and survival. The impact of quantitative feeding on nutritional parameters of fifth instar Antheraea mylitta larvae was studied by providing fresh leaves of Terminalia tomentosa for 1 to 4 times a day. All the parameters improved upon providing fresh diets more times over the single diet (1FD). The absolute body weight increased with increase in number of feeds/day significantly (P<0.001). While the maximum weight recorded was 29.61 g in 1FD, the respective weights for two feeds/day (2FD), three feeds/day (3FD) and four feeds/day (4FD) were 39.41 g, 40.63 g and 42.66 g respectively. Feeding period and instar duration were declined (P<0.001) and survival increased significantly (P<0.001) upon increase in the number of diets. Nutritional indices like ingestion, digestion, relative consumption rate (RCR), relative growth rate (RGR) and gain in body weight increased significantly with the increase in number of feeds/day, but approximate digestibility (AD) and efficiency of conversion of ingested food (ECI) declined, while efficiency of conversion of digested food (ECD) did not change.

  • This study tries to give an insight for fisheries policy makers to prepare policy proposals for Early Voluntary Sectoral Liberalization(EVSL) in the fisheries sector of APEC. To do so, the paper assesses the impact of EVSL on the fisheries sector, especially, Korean Deep-See Fisheries in quantitative way using the partial equilibrium analysis of Feenstra(1995). For the use of simple analysis, the paper focuses on the impact on trade flows and welfare of the elimination of tariffs on Korean Deep-See Fisheries among several measures of EVSL. The results from the quantitative analysis of the impact of EVSL on the Korean Deep-Sea Fisheries indicate that the increase of export is moderately higher than that of import and the total welfare effect is positive, even though a certain Deep-Sea Fisheries confronts a reduction of domestic supply basis.

  • This paper studies the impact of the maintenance time of anti-ship missile Harpoon on operational availability with real field data. The Harpoon maintenance simulation model is developed as a testbed for identifying the optimal inventory levels on operational availability. Using multiple linear regression analysis and integer programming, the optimal inventory levels of essential assemblies are suggested. Finally, the result of sensitivity analysis shows the quantitative impact of maintenance time on operational availability and inventory costs. The authors believe that this quantitative analysis can support policy decisions to decrease maintenance time of missiles.

  • The purpose of this paper was to analyze the content of impact prediction in EISS, in order to find the degree of the acuracy of impact prediction . 30 EISS were selected as analysis objects through variance miximization strategy. Content analysis of the selected EISS was performed by 5 analysis items, such as quantification of measurement, range of impact area, time frame of impact, likelihood of impact, and explict characterization of impact significance. The results showed that the accuracy investigated by the 5 items was very low. In conclusion, 5 suggestions were proposed in order to improve the credibility of EIS as a scientific report. The 5 suggestions were : 1) impact prediction should be described by quantitative measurement; 2) In establishing the time frame of the impact and the referent populatioin influenced by the impact, the characteristics of the proposed action should be carefully considerd; 3) the significance of the predicted impact should be quantitatively described; 4) specific description should also be used in the likelihood or the probability of the predicted impact in a real world; 5) equal emphasis should be put on the three environment, including natural and social as well as living environment.

  • 본 연구는 글로벌 제약 및 바이오 기업을 대상으로 내부특허, 산학특허, 매입특허의 양적 수준이 경영성과에 미치는 영향을 분석함으로써 내부특허 중심으로만 이루어진 기존연구들의 단점을 보완하고자하였다. 기존의 연구방식으로는 산학협력 및 매입을 통해 특허를 확보하고 있는 글로벌 대기업들의 경영성과를 설명하는데 어려움이 있었다. 특히 제약 및 바이오 기업의 경우 M&A를 통한 특허의 매입이 빈번히 일어나고 있어 매입 특허의 분석이 매우 중요함에도 불구하고 하나하나의 특허 명세서를 추적해 권리관계의 변동을 조사해야하는 어려움 때문에 연구가 진행되지 못했었다. 또한 연구방법 측면에서도 기존 성장모형에 특허가 경영성과에 영향을 주는데 걸리는 시간을 감안해 t-3년까지의 유한 시차를 고려한 확장모형을 제시했다. 분석결과 양적 특허수준은 매출에 미치는 영향은 적었고 시장가치에 상대적으로 큰 영향을 미쳤으며 수익에는 중간 정도의 영향력을 미쳤다. 3가지 특허중 기업의 시장가치에는 내부특허가 가장 큰 영향력을 미쳤고 매출과 수익에는 매입특허가 가장 큰 영향력을 나타내었다. 제약 바이오 기업에 있어서 매입특허가 경영성과에 중요한 영향을 미치는 것으로 나오는 이유는 제약 및 바이오 기업의 연구개발이 오랜 시간과 비용이 소요되며, 여러 가지 기술의 융복합이 필요한 연구이기 때문에 빠른 시간 안에 기술을 확보하는 것이 중요하고 이를 위해 기업들이 특허를 매입하거나 M&A를 함으로써 문제를 해결하고 있기 때문으로 판단되어진다. 본 연구는 글로벌 제약 및 바이오 기업들이 최적 특허 포트폴리오 구성을 할 수 있도록 도움을 줄 수 있을 것으로 기대한다.

  • This study developed and tested the impact of hallyu 4.0, social media, and consumer ethnocentrism on the decision to purchase Korean products of Generation C in Vietnam. Both qualitative and quantitative methodologies were utilized in this study. Qualitative research was first carried out with in-depth interview, conducted to derive measurement items for the interested constructs. Quantitative research used cross-sectional field design by pilot study and official study. The model was tested and developed using data collected by questionnaires, from a sample of 575 respondents, by both electronic and paper surveys with non-probability and convenience sampling techniques. SPSS 20 and AMOS 20 software were employed to analyze the data. The results of structural equation modeling showed that hallyu 4.0, social media, and consumer ethnocentrism influenced the intermediates variables: subject norms, trust, attitude and behavioral intention and influenced purchase decision. The hallyu 4.0, social media, and consumer ethnocentrism are independent variables. They impact purchase decision through mediating variables such as trust, subjective norms, attitude and behavioral intention. Social media influences not only to trust but also to subjective norms. Subjective norms influence on purchase decision. This study also discovers an interesting fact that trust and attitude variables have an impact on behavioral intention and purchase decision.
