The purpose of this study is to propose an open source GIS software business model for the revitalization of Korean open source GIS software industry. In this study, we categorized the types of open source software business models and developed an open source software business strategy suitable for GIS companies in Korea. To propose a business model, we applied the business model canvas which is often used in the area of business studies to analyze new business models. We tried to develop the open source GIS business model through both interviews and case studies with Korean open source GIS software companies. We propose three different types of open source GIS software business models such as distributor model, producer model, and 3rd party service provider model as follows: first, the companies which belong to distributor model can carry out business by providing professional services in the market of open source software. Second, the companies which belong to producer model can sell their products to the global market as well as the domestic market. Lastly, given the growing interest in domestic open source software, the number of third-party service providers is likely to continue to increase in the future. Therefore, it is expected that the companies which belong to the third party service provider model will be able to develop various business models by securing the technology.

In this paper, the proposing a fundamental data for a systematic and effective organizational management by examining the extent of the levels of conflict perceiving among individuals of social welfare workers in the Busan community social welfare center, a social welfare organizations, and investigating the related influencing factors are the purpose of the study, The summary of this study is as follows. At first, it is dysfunctional when the level of conflict is either exceedingly high or low in the interrelational conflict aspect. However, the social welfare workers' working in the community social welfare center, the extent of individual conflict is relatively low as 2.37 out of 5 points. Secondly, the multi-regression analysis is operated for controlling the population sociological factors and measuring the effectiveness of the conflict factors to the level of conflict. The influencing factors affects the result in the order of greater extent are communication factor, leader's flexibility of leadership factor, spontaneity among personality, confidentiality. As a result, Not like the case that in the technological bureaucratic organizations such as the enterprises or industrial organizations, in the human service organizations including social welfare organizations, these technological bureaucratic paradigm does not applying directly since the material of organization is composed of humans who are given moral values. Therefore, this paradigm should be put as a presupposition of the conflict management strategy. And, the communication among colleagues, learning a reasonable problem solution method, or the chances of education or training for establishing a sound human relationship should be prepared in order to lower the level of the conflict among individuals in the community social welfare department. Furthermore, professional education programs are needed for not only supporting an effective supervision and consultation(consultation with superiors and colleagues), but also, working with confidentiality and pride as a professional.

Each country has set low-carbon green growth to a new growth drive for the future while making various efforts. Accordingly, our country also set green growth to our policy task in top priority throughout our country while initiating various policies. Our country has focused on initiating a few policies in green growth. Our country has focused on the development of green industries to secure our national competitiveness while generating added values in green growth. It is necessary to have studies in initiating policies in balance when we consider that green growth should be initiated through the shift over the whole lifestyle. On the other hand, policies led and driven by the central government have been emphasized. Although the planning and establishment of policies might be said to fall under the central government's main areas, green growth policies can be realized regionally in the end. Considering these circumstances, the coordination in a proper way between the central government and each municipality can also be seen as major characteristics only in our country, which can be hardly seen in other countries. This study aims at developing the initiative strategies in our country's green logistics while analyzing the characteristics of green growth and situations of green logistics initiative, studying the government's policies to support green logistics, reviewing the government's policies for supports, and suggesting alternatives for them.

Aromatic compounds are widely used in the chemical, food, polymer, cosmetic, and pharmaceutical industries and are produced by mainly chemical synthesis using benzene, toluene, and xylene or by plant extraction methods. Due to many rising threats, including the depletion of fossil fuels, global warming, the strengthening of international environmental regulations, and the excessive harvesting of plant resources, the microbial production of aromatic compounds using renewable biomass is regarded as a promising alternative. By integrating metabolic engineering with synthetic and systems biology, artificial biosynthetic pathways have been reconstituted from L-tryptophan biosynthetic pathway in relevant microorganisms, such as Escherichia coli and Corynebacterium glutamicum, enabling the production of a variety of value-added aromatic compounds, such as 5-hydroxytryptophan, serotonin, melatonin, 7-chloro-L-tryptophan, 7-bromo-L-tryptophan, indigo, indirubin, indole-3-acetic acid, violacein, and dexoyviolacein. In this review, we summarize the characteristics, usage, and biosynthetic pathways of these aromatic compounds and highlight the latest metabolic engineering strategies for the microbial production of aromatic compounds and suitable solution strategies to overcome problems in increasing production titers. It is expected that strain development based on systems metabolic engineering and the optimization of media and bioprocesses using renewable biomass will enable the development of commercially viable technologies for the microbial production of many aromatic compounds.

In addition to recession, world shipping companies are undergoing restructuring due to excess of "World Container Cargo volume" per "World Containership capacity" (in TEU terms). This excess is attributed to the absence of standard index of calculating the "World Containership capacity" (in TEU terms) for "World Container Cargo volume." The purpose of this study is to develop indices and terms: "World Containership capacity (in TEU terms) Standards Index; WCSI" and "World Containership capacity (in TEU terms) Expected Index; WCEI." The comparison between "WCSI" and "WCEI" made in this study is presented below. WCSI (Average voyage 9.3) > WCEI Excess shipping (in TEU terms) WCSI (Average voyage 9.3) = WCEI Optimum shipping (in TEU terms) WCSI (Average voyage 9.3) < WCEI Short shipping (in TEU terms) WCSI=HRCI $1000{\pm}150$ Value approx. The study shows that it is possible to predict "optimal supply of the world's containership capacity" (in TEU terms), "excess or shortage of shipping" (in TEU terms), "order time of container-ship capacity building" (in TEU terms), "order quantity of containership capacity" (in TEU terms), and "stable of World Shipping Companies" by "WCSI" and "WCEI." The development of "WCSI" and "WCEI" aim to help overcome the crisis of recession by establishing effective business strategies for world shipping companies and their supporting companies.

High-grade limestone applied to various chemical industries is abundant within upper Pungchon formation in Taebaeksan basin, South Korea. Geophysical exploration is one of the most efficient methods to investigate subsurface geological structure in an extensive area. Since the geophysical exploration for the high-grade limestone has rarely been conducted in Korea, its appropriate strategy has not been set up yet. In this study, we focused on to suggest the reasonable strategy and accumulate geophysical databases which are essential for interpreting geophysical images by characterizing laboratory physical properties of in-situ rocks. Hence, rocks were obtained from drilled cores consisting of lower Hwajeol formation, Pungchon formation, and dykes in Jeongseon area, Gangwon province. Geophysical laboratory experiments and petrography of the rocks were conducted. Since susceptibility values of the rocks in Pungchon Formation were obviously lower than those of upper Hwajeol and dykes, it is considered that the lithological boundaries could be distinguished by magnetic survey. In addition, electrical properties of the rocks in middle Pungchon formation were relatively different compared with those of upper/lower Pungchon formations. Thus, induced polarization is shown to be able to detect the high-grade limestone in upper Pungchon formation.

Numerous observations revealed strong evidence of increased middle ultraviolet radiation or UV-B (280 ~ 320 nm) at the earth's surface resulting from stratospheric ozone depletion. UV is the waveband of electromagnetic radiation which is strongly absorbed by nucleic acids and proteins, thus causing damage to living systems. It has been recorded in the East Sea, Korea that solar UV-B impinging on the ocean surface penetrates seawater to significant depths. Recent researches showed that exposure to UV-B for as short as 2h at the ambient level (2.0 Wm$^{-2}$) decreased macroalgal growth and photosynthesis and destroyed photosynthetic pigments. These may suggest that UV-B could be an important environmental factor to determine algal survival and distribution. Some adaptive mechanisms to protect macroalgae from UV-damage have been found, which include photoreactivation and formation of UV-absorbing pigments. Post-illumination of visible light mitigated UV-induced damage in laminarian young sporophytes with blue the most effective waveband. The existence of UV-B absorbing pigments has been recognized in the green alga, Ulva pertusa and the red alga, Pachymeniopsis sp., which is likely to exert protective function for photosynthetic pigments inside the thalli from UV-damage. Further studies are however needed to confirm that these mechanisms are of general occurrence in seaweeds. Macroalgae together with phytoplankton are the primary producers to incorporate about 100 Gt of carbons per year, and provide half of the total biomass on the earth. UV-driven reduction in macroalgal biomass, if any, would therefore cause deleterious effects on marine ecosystem. The ultimate impacts of increasing UV-B flux due to ozone destruction are still unknown, but the impression from UV studies made so far seems to highlight the importance of setting up long-term monitoring system for us to be able to predict and detect the onset of large -scale deterioration in aquatic ecosystem.
