This study investigated the pollution characteristics of the main pollution zone in the Hwangguji watershed and the influence of the tributary on the main stream. The characteristics of the main pollution zone, including, the water quality index (WQI), stream rating, load duration curve (LDC), delivery load density (DLD), and contribution of the tributary to the mainstream, were evaluated by time-series visual heatmap. The WQI of the mainstream of Hwangguji was lowered to the poor (IV) level from the inflow point of Suwon stream (SW) and the LDC excess rate in the T-P was higher than that of BOD₅, especially for the wet season, suggesting that management of non-point source with T-P is preferred. The contribution (%) of the tributaries in the upstream section of Hwangguji watershed were BOD₅ 14.54%, TOC 15.67%, T-N 5.43%, and T-P 6.97%. In particular, the Suwon sewage treatment plant located in the mainstream showed a high contribution of BOD₅ (64.40%) and T-P (53.54%), respectively, due to the high discharge rate (6.019 m³/sec). Meanwhile, Sammi and Gal stream have a large impact on the mainstream with high DLD and poor WQI. Thus, both streams were considered as pollution hot spots. These results provide useful basic data for preparing more effective water quality improvement and management plans in the watershed.

Nine FTA like Korea-Chile FTA, Korea-Singapore FTA, Korea-EFTA FTA, Korea-ASEAN FTA, Korea-India CEPA, Korea-EU FTA, Korea-U.S.A. FTA, Korea-Peru FTA and Korea-Turkey have been concluded and implemented in 46 countries as of May, 2013. In addition to these nine FTA, Korea has been negotiating FTA or CEPA(Comprehensive Economic Partnership Agreement) with China and Vietnam and Indonesia. Now Korean government is about to conclude FTA agreement with Indonesia which is one of crucial trading partners in Asian countries so the objective of this paper is to suggest how to design ROO schemes properly in such upcoming FTA agreement since more activation of trade and more utilization of FTA can be depend on the details of ROO schemes. As a result, this paper suggests well-design of ROO schemes as follows ; First, self-issuance origin proof system can be considered because authority-issuance origin proof system may reduce the utilization ratio of FTA. Second, combination of indirect and direct verification system in terms of origin verification system will be more preferable because this will be more fitting to Asian countries as considering trading environments and characteristics of Asian market. Third, criteria to determine origin can be based on wholly obtained plus substantial transformation system which contains CTC plus VC along with some percentage of de minimis. In addition to this, the number of products stipulated in PSR should be minimized and applied similar manner to avoid complexity of deciding origin.

The purpose of this study is to qualitatively identify the typologies and characteristics of the big data marketing strategy in major companies that are taking advantage of the big data business in Korea. Big data means piles accumulated from converging platforms such as computing infrastructures, smart devices, social networking and new media, and big data is also an analytic technique itself. Numerous enterprises have grown conscious that big data can be a most significant resource or capability since the issue of big data recently surfaced abruptly in Korea. Companies will be obliged to design their own implementing plans for big data marketing and to customize their own analytic skills in the new era of big data, which will fundamentally transform how businesses operate and how they engage with customers, suppliers, partners and employees. This research employed a Q-study, which is a methodology, model, and theory used in 'subjectivity' research to interpret professional panels' perceptions or opinions through in-depth interviews. This method includes a series of q-sorting analysis processes, proposing 40 stimuli statements (q-sample) compressed out of about 60 (q-population) and explaining the big data marketing model derived from in-depth interviews with 20 marketing managers who belong to major companies(q-sorters). As a result, this study makes fundamental contributions to proposing new findings and insights for small and medium-size enterprises (SMEs) and policy makers that need guidelines or direction for future big data business.

Purpose: Most enterprises adopt six sigma acts to maximize the business performance with raising the executiveness for the project improvements in each parts. But there are little studies about six sigma actual operations in manufacturing whether the six sigma improvements that have injected a lot of budget, efforts, labours and time are run properly. Methods: This study select 31 interviewees who have MBB or BB from 5 large enterprises running six sigma over 10 years and 5 SMEs running six sigma over 5 years to understand and review the operational status of six sigma actions in manufacturing industry and to secure representativeness. This study identify the operational status of six sigma actions and key factors enhancing or impeding execution of six sigma projects through face-to-face interviews and online surveys by e-mail. Results: This study figured out the operational status of six sigma actions and key factors enhancing or impeding execution of six sigma projects. We used SPSS 16.0 for the reliability and the validity of survey data. Conclusion: There can be a lot of different factors that affect six sigma project improvements besides the key factors from this study. More study need to think of the organization characteristics and the basic conditions and to remedy the unreasonable points and defects rather than following foreign companies and enterprises.

Background: In the etiology of cervical cancer not only HPV infection is important, but also other factors such as demographic influences andsexual and reproductive health attitudes, as well as others related to preventive measure usage (or non usage). The aim of this study was to examine factors associated with cervical dysplasia in asymptomatic women who were examined by routine cytology and cervical biopsy for early detection of cervical cancer. Materials and Methods: Socio-demographic and other characteristics were obtained from medical files of 85 examinees with pathologic cytologic findings (Pap test) and histopathologic (HP) findings after biopsy. Results: ccording to the Pap test result, a greater probability for development of cervical dysplasia was noted with examinees having a larger number of sexual partners (OR= 5.01, 95% CI 1.04-24.10), and those who are afraid of the Pap finding. Risk factors for development of cervical dysplasia according to the bioptic finding were early beginning with sexual activities, presence of any STD in personal medical history and fear of the Pap test finding. Conclusions: The only risk factor found to be important for both methods was fear of the Pap testing finding.

North Dakota State University (NDSU) Extension Service's purpose was to create a learning partnership that helped adults and youth enhance their lives and communities. NDSU Extension Service has maintained a strong blend of county, regional and state staff to support their program delivery. Experiment Station and Extension Service were integrated both in their job duties and at the administrative level. While researchers at the campus and center carried out both research and outreach activities with producers, Extension staff both at county and center carried out some research activities as well as outreach activities. The strong county-based Extension network was the main avenue for program delivery. Extension agents also provide programs on a multi-country basis. Program planning includes county advisory councils, multi-county advisory councils, support groups, and commodity groups, such as farmers and business people. Planning was used to shape their long-range plan of work along with adjustments to their annual activities. Funding of the NDSU Extension Service has been a blend of federal, state, and county dollars. In the past few years, grant dollars and agency partnerships have increased. Local input into extension programs, combined with support and funding from state and federal partners, enabled the extension service to truly meet the needs of people.

The collaboration is becoming ever more widespread in scientific research. Unlike collaboration in other areas such as in a company, research collaboration has an unique feature that it is reflected by scholars' characteristics. Based on previous studies on research collaboration, five major factors are identified. We propose five hypotheses from them and examine these by using both in-person questionnaire survey and relational bibliometric analysis. The survey analysis informs individual choice factors and the bibliometric analysis informs collective consequence factors. The results of this study may have implications for science policies and digital collaboration services.

Purpose: The purpose of this study was to grasp the level of effects innovative features and quality of the appliance system on organizational performance and ultimately analyze the willingness of the IT staff to adopt an appliance system. Methods: The survey was conducted on 350 vendors' clients and partners who currently use an appliance system from March to May 2014. A total of 331 effective questionnaires were collected and analyzed using PASW18 and SmartPLS. Results: The results show that relative advantage, facilitating condition and trialability and quality factors all had an effect on organizational performance expectations. Further, when an appliance system is adopted, it was shown that cost and reliability emphasized by a vendor did not produce any significant effects on organizational performance expectations. Conclusion: This study is significant as it is the first to combine such models as Innovation Diffusion Theory, Information Systems Success Model, and Unified Theory of Acceptance and Use of Technology with a new external variable. In addition, it illustrated how variables affect the adoption of an appliance system such as a new innovation system.

The purpose of the paper is to find out the trade patten and characteristics of Korea's fisheries products by figuring out the factors of affecting the volume of the export of Korean frozen fisheries products based on the data of frozen fisheries (HS0303), which make up of the large volume of Korea's fisheries export using gravity model. The paper has performed regression analysis through using 624 panel data and the statistical program, STATA 12.0. In this study, we can get two results as follows: First, the total import volume of fisheries and transportation distance of trade partners have an influence on the Korea's trade of frozen fisheries products. The time and fare of transportation have also an influence on the Korea's trade of frozen fisheries products. Second, Korea's trade of frozen fisheries products is also affected by the exchange rate of currencies and settlement of FTA which could be shown as important factors in the estimation of export function of general products.
