Rapid and reckless economical development is causing nationwide deforestation; more and more forest is being developed to be used as a base for economic advancement. While benefiting the national economy, this destruction of forest is creating a serious problem in the National Land Plan. To solve this problem, it is imperative to understand the current condition of damaged forest and make an environment-friendly plan. This paper explains the principles of spatial plan and sets the criteria for the plan, such as patch size, connectivity, and edge of the Landscape Ecology. The paper assesses the conservational value of area that are currently being developed or planned to be developed to figure out the current environmental situation. This conservational value was verified by the field survey. The result of assessment appears that the patch size of the major mountains in site is over 1,000ha and edge is located widely beside roads. The area of the high connectivity is located agriculture area in valley or narrow roads. The research shows that the patch size is related to biodiversity the larger the patch size, the more populated the species are. The research also reveals the conservational value indicated by degree of connection to forest, difference in the structure of vegetation between core area and edge area, and effects of surrounding environment. In further study, we will assess other criteria of conservation value, such as patch shape and fragmentation to the Landscape Ecology, and apply those criteria in biological aspects of the spatial plan.

This article proposes a logic model for assessing the performance of the outcome of public research as a technology valuation method. It consists of two parts and eight steps. The first part is a scoring system and the second part is a validation process of the performance index derived from scoring by valuation method. The scoring in the first part generally requires a focus group method to find out the value drivers and make an evaluation table. The reason why we call it the technology valuation method is that the first part is derived from the simple evaluation of technology value using checklists for value drive. The second part is the regular technology valuation process. The model is designed for the measurement of unquantifiable outcome. Is knowledge or scientific outcome comparable to the measured outcome? If possible, how big is the unquantifiable outcome? This model is based on financial valuation techniques with clear or acceptable market data. Therefore, it cannot work solely for unquantifiable outcomes without comparable measurable outcomes, unlike economic valuation.

With the globalization of economy, industries are facing increasingly greater challenges. Business integration, both internally and externally, is undoubtedly an important topic. However, how does an enterprise create its own value will be the key to an enterprise's success in the future. Therefore, this study bases on the evaluation of company value to assess the key factors and competitive strategies of an enterprise. Yet, only with stable enterprise performance can the company value be correctly evaluated. This will be an important issue for enterprise performance and business strategy. Subject of this study are mainly small and medium-sized (enterprises (SMEs). Model construction for SME value assessment is established through the system dynamics approach. Scholars' opinions on literature validation and application of Delphi Method are explored through literature review on local and foreign studies, in order to compile the relevant perspectives and indices for enterprise value creation. Hence model construction of the value creation system is established, and the correlation between the perspectives and related factors is explored to understand the overall dynamics model of SMEs' value creation system. Consequently, a research method based on the system dynamics perspective is provided for the study of enterprise value creation is provided, as policy reference for improvement of decision-making and value creation.

The current study was conducted to make pre-post comparisons of education done for 119 emergency medical technicians (EMT) on the patient assessment performance. The data are expected to offer applicable training methods and educational resources for emergency medical services. Twenty six EMT from four cities and provinces participated in the study, which was carried out from 14 to 17 December, 2015. The technicians performed a patient assessment and marked reports on simulated patients. In the course of the assessment, a pre-post evaluation of education was done using a checklist regarding the respective symptoms, such as headache, chest pain, and dyspnea. The median value (quartile value) was used as the descriptive analysis. While patient assessment scores marked 66 points (54.00-80.25) out of 100 (p<0.01) before education, there was a significant increase in the after-education scores, which reached 88.5 points (80.00-93.00). The patient assessment performances revealed a significant increase (p<.0.01) in 5 chest pain, 7 headache, and 9 dyspnea items after education. Similarly, there was an increase in wanting to meet the EMT again scale in regards to categories involved in developing positive relations with patients. Moreover, the adequacy in the patient condition reports all marked a significant increase (p<0.01) in assessment categories. The present study shows that education based on simulation practices are necessary for improvements in patient assessment performance of 119 EMT. Therefore, practical and systematic patient assessment educations may serve as a prerequisite. Further opportunities should be provided for the EMT consistently.

Yield-per-recruit (YPR) analysis is used to provide management guidance for the efficient use of a fish cohort. However, the individual fish price per unit weight of small yellow croaker (Larimichthys polyactis) or hairtail (Trichiurus lepturus) increases dramatically by size in Korea. Therefore, age-based production value-per-recruit (PPR) analysis has recently been developed (Zhang et al., 2014). Since age determination requires a substantial amount of money and time and it is even impossible for some fish species, it is difficult to obtain age information to apply the age-based PPR model. Thus, we attempted to develop an alternative method, which uses length data rather than age information, called the length-based PPR analysis. The results revealed that length-based PPR analysis was much more conservative for stock management than the YPR analysis. Furthermore, the PPR analysis was more economically beneficial than the YPR analysis, which can prevent the fish stock from the economic overfishing. In conclusion, the length-based PPR analysis could be a proper approach for stock assessment in the case that the individual fish price per unit weight increases dramatically by size, and this analysis is useful to obtain vital management parameters under data-deficient situation when traditional stock assessment methods are not applicable.

Since the government of Korea (Ministry of Environment, MOE) introduced the policy applying 'Biotope-Area-Ratio-Indicator (BARI)' to huge residential land developments which Environmental Impact Assessment (EIA) should be performed, MOE has come to have the necessity to apply the indicator concretely at the stage of Prior Environment Review System (PERS) and EIA in various types of large scale land development projects. This study was conducted with the aim of supporting the application of BARI and related decision making in various other types of EIA projects as well as residential development projects through remodeling the system to apply the indicator of the past. Through the analysis of the problems in applying the past BARI and experimental appraisals to 11 types of EIA projects, the results and implications as follows were drawn. First, it's possible to extend the range of applications of BARI, which has been applied to only residential land development project, to all kinds of projects with area-typed land use pattern out of environmental impact assessment target projects. Second, it's also possible to set a target value into which regional characteristics and differences among locational properties are reflected. In addition, it's come to be able to differentially apply the target value of BARI according to the condition of the existing site. Third, it's improved to be able to suggest a macroscopic target value at the stage of PERS and to set detailed target values in each detailed land use at the stage of EIA. The key point underlies inducing methodology to determine target values to secure more permeable land coverage ratio for detailed land use patterns at the stage of EIA by making it possible to calculate BARI of the present land cover condition of the EIA target projects.

In spite of the ecological value of the DMZ, there have not been established guidelines for sustainable conservation and use on the DMZ and adjacent area. In this study we suggested a method about zoning the conservation and utilization area considering environmental data and the characteristic of the DMZ region, and we make the guideline for conservation of the DMZ region based on the zone. Using 10 legal protection areas, the Environmental Conservation Value Assessment Map (ECVAM) and the boundaries of the DMZ region, we evaluated this region into conservation areas, management areas, and utilization areas. The results showed that as much as 91.8% of the DMZ region was evaluated as conservation areas, 6.9% as management areas, and 1.3% as utilization areas. After consultation with experts we suggested management principles, the direction, and the guideline based on the planning process considering the evaluation map. The study suggests principles and guidelines for management, and the guidelines could be a effective tool for the sustainable conservation and management strategy of DMZ region.

Background: After the Fukushima accident, the importance of hazard analysis for extreme external events was raised. Methods: To analyze typhoon-induced hazards, which are one of the significant disasters of East Asian countries, a statistical analysis using the extreme value theory, which is a method for estimating the annual exceedance frequency of a rare event, was conducted for an estimation of the occurrence intervals or hazard levels. For the four meteorological variables, maximum wind speed, instantaneous wind speed, hourly precipitation, and daily precipitation, the parameters of the predictive extreme value theory models were estimated. Results: The 100-year return levels for each variable were predicted using the developed models and compared with previously reported values. It was also found that there exist significant long-term climate changes of wind speed and precipitation. Conclusion: A fragility analysis should be conducted to ensure the safety levels of a nuclear power plant for high levels of wind speed and precipitation, which exceed the results of a previous analysis.

Under circumstances with increasing uncertainty, strategic flexibility has become an essential point on which my R&D management system should be based. Unfortunately the present R&D management system for government sponsored R&D programs cannot be said to be so flexible to adapt appropriately to various threatens such as technological failure, a severe change in competition environment, and so on. In this paper a new scheme for R&D planning and economic assessment with strategic flexibility is suggested and applied to a real R&D program. In the newly suggested R&D management system, economic valuation based on real option theory is performed for various alternative scenarios which have different strategic scheme for R&D process each and the result of the assessment is fed back to R&D planning to choose more superior strategic scheme. Introducing strategic flexibility into R&D planning and economic assessment, the value of R&D project could be remarkably enhanced.
