This study analyzes the process of establishing BSC based strategic performance evaluation system of KOMSCO. This case could be a reference to other public institutes for BSC introduction and efficient BSC usage. Internal control system of KOMSCO has been improved by EVA system in 1999, BSC introduction and Job analysis in 2001 through 2002, and BSC performance evaluation system in 2004. KOMSCO tries to reflect BSC concept by inducing employees to cooperate selection process of CSF and KPI and by considering the organizational characteristics of KOMSCO in constructing it's performance indices. It is suggested that these processes are very important and should be followed by other institutes in their BSC introduction. By applying BSC, KOMSCO provides improvement in employees' understanding of strategy, performance management, and performance evaluation. KOMSCO' information system based on ERP and efficiently connected to EIS, KMS, and BSC seems to play an important role of BSC application. BSC system of KOMSCO is now in the early stage of application and needs to be evaluated by the efficiency of usage in terms of overall performance evaluation system, deduction system of evaluation point for excess accomplishment over target, and connection to budget system.

Traffic Matrix estimation has always caught attention from researchers for better network management and future planning. With the advent of high traffic loads due to Cloud Computing platforms and Software Defined Networking based tunable routing and traffic management algorithms on the Internet, it is more necessary as ever to be able to predict current and future traffic volumes on the network. For large networks such origin-destination traffic prediction problem takes the form of a large under- constrained and under-determined system of equations with a dynamic measurement matrix. Previously, the researchers had relied on the assumption that the measurement (routing) matrix is stationary due to which the schemes are not suitable for modern software defined networks. In this work, we present our Compressed Sensing with Dynamic Model Estimation (CS-DME) architecture suitable for modern software defined networks. Our main contributions are: (1) we formulate an approach in which measurement matrix in the compressed sensing scheme can be accurately and dynamically estimated through a reformulation of the problem based on traffic demands. (2) We show that the problem formulation using a dynamic measurement matrix based on instantaneous traffic demands may be used instead of a stationary binary routing matrix which is more suitable to modern Software Defined Networks that are constantly evolving in terms of routing by inspection of its Eigen Spectrum using two real world datasets. (3) We also show that linking this compressed measurement matrix dynamically with the measured parameters can lead to acceptable estimation of Origin Destination (OD) Traffic flows with marginally poor results with other state-of-art schemes relying on fixed measurement matrices. (4) Furthermore, using this compressed reformulated problem, a new strategy for selection of vantage points for most efficient traffic matrix estimation is also presented through a secondary compression technique based on subset of link measurements. Experimental evaluation of proposed technique using real world datasets Abilene and GEANT shows that the technique is practical to be used in modern software defined networks. Further, the performance of the scheme is compared with recent state of the art techniques proposed in research literature.

Positioning technique which has been widely used for making marketing strategy by analyzing customer's image also has been used for public and test-taker's image analysis about public facilities, entrepreneurs, universities. This study analyze image of library and Information science students who trying to find a job in library fields about diverse types of library and information centers by Positioning technique. As a result of Similarity cognition analysis by multidimensional Scaling and K-means clustering, it was found that students recognize that public, national, university, school library are similar, on the other hand, portal company and special library are different from those types. In the jobs, user service jobs and technical service jobs are recognized as separated clusters, and cultural program job is also recognized dissimilarly from those clusters. By the way, images about work satisfaction and stability of employment shows high in national library; high wage shows high in portal company; employee's growth potential shows high in special library; job importance shows high in reference service jobs; difficulty shows high in content's job. Anyway, in the workplace selection, almost students regard stability of employment as top priorities, accordingly they prefers public library at most. Such a preference concentration tendency is strongly appeared in local university students than in metropolitan area students as a result of Pearson's chi-square test.
Winterkill can be defined as any injury including freeze stress kill, winter desiccation, and low temperature disease to turfgrass plants that occurs during the winter period. The major damages from winterkill were low temperature kill, crown hydration, and winter desiccation. Low temperature kill is caused by air and soil temperature. Soil temperature affect more severe to turfgrass than air temperature because low soil temperature cause fetal damage to turfgrass crown. Crown hydration is a form of winter injury in which intercellular water within the plant freezes and causes physical injury to the cell membrane and wall. This is eventually resulted in dehydration of cell. Winter desiccation is the death of leaves or whole plants due to drought during the winter period. To reduce winterkill damage, cultivar selection is very important. If changing cultivar is not allowed, cold temperature hardiness needs to be increased by providing nutrients especially phosphorus and potassium in the late fall. Turf cover is effective way to reduce winterkill damage. Remaining snow is positive process to reduce winterkill damage by insulating soil temperature. The previous researches reported many materials as turf cover such as straw, polypropylene, polyester, and wood mat. Aeration and topdressing is one of the process against winterkill. Both methods are mainly conducted to reduce thickness of thatch layer. In recent, relatively new materials called black or winter topdressing sand are used to protect soil temperature from low air temperature and thaw ice crystal that may remain in soil.

This study employed inter-simple-sequence repeat (ISSR) to assess genetic variation among 189 individuals representing 10 populations (nine in Korea and one in Japan) of Millettia japonica, which has recently been lifted from the endangered species of Korea. The calculated Shannon's information index value (I = 0.2689) of the species was appreciable and was higher than other endangered leguminous woody taxa. Gochang (I = 0.2968), Namhae (I = 0.2951), and Mt. Toham (I = 0.2823) populations showed relatively high genetic diversity, whereas the Kyushu (in Japan) population (I = 0.2487) exhibited the lowest. The results of an analysis of molecular variance indicated that 86.49% of the diversity was attributed to within populations, and 13.51% to differences among populations, suggesting that M. japonica populations do not have significant geographic differentiation and that the gene flow between populations exists to some extent (Nm = 1.8446). Continuous habitat monitoring should be conducted to conserve genetic diversity of M. japonica, particularly for those populations with relatively high genetic diversity. Selection of many individuals from the populations in Gochang, Namhae, and Mt. Toham is thought to be an appropriate strategy for ex situ conservation of M. japonica in Korea.
Remarkable scientific and technological achievements are mainly shown in the 'super-convergence' or 'convergence of convergence' among cross- disciplinary fields, and advanced countries are promoting the 'high-risk, high-return research' ecosystem. Google LLC is carrying out numerous new challenges in terms of a non-failure perspective. Innovative research by the US Defense Advanced Research Projects Agency (DARPA) has produced such breakthroughs as the Internet, GPS, semiconductors, the computer mouse, autonomous vehicles, and drones. China is pioneering a 'Moon Village' and planning the world's largest nuclear fusion energy and ultra-large particle accelerator project. Japan has also launched 'the moonshot technology development research system' to promote disruptive innovation. In Korea, the government is preparing a new research program to tackle the global scientific challenges. Therefore, it is necessary to determine the reasonable geoscientific challenges to be addressed and to conduct a preliminary study on these topics. For this purpose, it is necessary to conduct long-term creative research projects centered on young researchers, select outstanding principal investigators, extract innovative topics without prior research or reference, simplify research proposal procedures, innovate the selection solely based on key ideas, and evaluate results by collective intelligence in the form of conferences.
As the environment of Logistics is changing rapidly, the environment of port is also changing. Accordingly, rapid change within port environment appears as the increase of the volume for world wide cargo, liner ship owners' strategy shift, globalization of terminals, heavy competitions to become a hub of Logistics, development of ship engineering. Therefore, the people who are responsible for the operations and managements of ports foresee such changes and accordingly react to ensure competitiveness. As the competition among ports generally goes international, a port needs to be sure that they become superior to any other port regardless of whether it's outside their country or not. Especially Korea is located in the most heavily competitive area which is Far-East. So if we fail to get competitiveness against the other ports, it goes without saying that our ports will be defeated by them. In brief, this paper will discuss the history of study regarding the factors by which a port is selected and also suggest some of elements which can be applied to small ports in the future of it.

An objective of VMS(Variable Message Signs) is to make transportation system effective specifically for driver's path selection. The traffic solutions including a VMS problem can be modeled through Game Theory, however, the majority of the studies can not model various driver's response according to VMS information in game theory. So, this paper tries to analyze a driver's response according to VMS traffic informations through evolutionary game theory. We apply a behavior characteristics of driver to evolutionary game theory, then finds drivers are only accepting in case of the biggest pay-off, and if a traffic flow finds a balance over time, ratio of accepting information is converged as an evolutionary stable state gradually. Consequently, the strategy of the other drivers such as traffic problems can not be predicted accurately. In case, drivers repeat between groups and reasonable judgment by the experience, we expect that VMS can provide strategic information through evolutionary game theory.
A lot of Pond Wetland (Palustrine Wetland) are distributed in agricultural landscapes, Korea. These wetlands are evaluated as important resources for conservation of biodiversity. However, the study of Pond Wetland is rarely conducted except type classification in Korea. In this study, the function of pond wetland as ecosystem services is studied for conservation and utilization of wetland. Research was conducted in three steps; functionality analysis, functionality derivation, and importance analysis. A total of 22 features were derived by analyzing the previous studies. As a result of expert survey, 4 features were selected by each in the field of biological, environmental, and socio-culture among the 22 features. Importance was calculated by conducting a cross-functional features using Analytic Hierarchy Process (AHP). Finally, 10 ecosystem service functions of pond wetland were derived through expert survey; (1) Water Storage & Irrigation, (2) Vegetation Diversity, (3) Amphibian & Reptile Habitat, (4) Water Purification, (5) Aquatic Insect Habitat, (6) Nutriments Control was derived, (7) Groundwater Recharge, (8) Fishery Habitat, (9) Eco-Experience & Education, and (10) Aesthetic landscape. It is expected that this study is able to utilize in evaluation of pond wetlands ecosystem services by further study on analysis of functional importance and economic value index.
