  • The input emergy of an advanced treatment plant for reducing the 1 kg of TN and TP was estimated 4.14E+14 sej/kg, 5.02E+15 sej/kg, respectively. In addition, the input emergy of constructed wetland for reduction of the 1 kg of TN and TP reduction was estimated to be 2.48E+14 sej/kg, 3.38E+15 sej/kg, respectively. The cost reducing 1 kg of TN and TP for an advanced treatment plant was estimated 197,466 won and 2,388,739 won respectively and constructed wetland was estimated 117,976 won and 1,609,213 won respectively. As a result, All of the emergy source of constructed wetland for reducing non-point source is renewable resource. If we use the constructed wetland, it results in enhancing economic value by reducing of non-point pollution, controlling a flood and providing the habitat of animals or plants. Improving water quality program in the Nakdong River Basin should be changed into an ecological treatment facilities from expansion of the sewage treatment facilities and advanced treatment plant using high cost and non-renewable energies.

  • Despite the enforcement of SSM control laws such as 'the Law of Developing the Distribution Industry (LDDI)' and 'the Law of Promoting Mutual Cooperation between Large and Small/medium Enterprises (LPMC)' stipulating the business adjustment system, the number of super-supermarkets (SSMs) has ever been expanding in Korea. In France, however, Super Centers are being regulated most strongly and directly in the whole Europe viewing that there is not a single SSM in Paris, which is emphasized to be the outcome from French government's regulation exerted on the opening of large scale retail stores. In France, the authority to approve store opening is deeply centralized and the store opening regulation is a socio-economic regulation driven by economic laws whereas EU strongly regulates the distribution industry. To control the French distribution industry, such seven laws and regulations as Commission départementale d'urbanisme commercial guidelines (CDLIC) (1969), the Royer Law (1973), the Doubin Law (1990), the Sapin Law (1993), the Raffarin Law (1996), solidarite et renouvellement urbains (SRU) (2000), and Loi de modernisation de l'économie (LME) (2009) have been promulgated one by one since the amendment of the Fontanet guidelines, through which commercial adjustment laws and regulations have been complemented and reinforced while regulatory measures have been taken. Even in the course of forming such strong regulatory laws, InterMarche, the largest supermarket chain in France, has been in existence as a global enterprise specialized in retail distribution with over 4,000 stores in Europe. InterMarche's business can be divided largely into two segments of food and non-food. As a supermarket chain, InterMarche's food segment has 2,300 stores in Europe and as a hard-discounter store chain in France, Netto has 420 stores. Restaumarch is a chain of traditional family restaurants and the steak house restaurant chain of Poivre Rouge has 4 restaurants currently. In addition, there are others like Ecomarche which is a supermarket chain for small and medium cities. In the non-food segment, the DIY and gardening chain of Bricomarche has a total of 620 stores in Europe. And the car-related chain of Roady has a total of 158 stores in Europe. There is the clothing chain of Veti as well. In view of InterMarche's management strategies, since its distribution strategy is to sell goods at cheap prices, buying goods cheap only is not enough. In other words, in order to sell goods cheap, it is all important to buy goods cheap, manage them cheap, systemize them cheap, and transport them cheap. In quality assurance, InterMarche has guaranteed the purchase safety for consumers by providing its own private brand products. InterMarche has 90 private brands of its own, thus being the retailer with the largest number of distributor brands in France. In view of its IT service strategy, InterMarche is utilizing a high performance IT system so as to obtainas much of the market information as possible and also to find out the best locations for opening stores. In its global expansion strategy of international alliance, InterMarche has established the ALDIS group together with the distribution enterprises of both Spain and Germany in order to expand its food purchase, whereas in the non-food segment, it has established the ARENA group in alliance with 11 international distribution enterprises. Such strategies of InterMarche have been intended to find out the consumer needs for both price and quality of goods and to secure the purchase and supply networks which are closely localized. It is necessary to cope promptly with the constantly changing circumstances through being unified with relevant regions and by providing diversified customer services as well. In view of the InterMarche's positive policy for promoting local partnerships as well as the assistance for enhancing the local economic structure, implications are existing for those retail distributors of our country.

  • Background: Due to the rapid progress of industrialization, the expansion of the nuclear family, and an increase in women's social activities, the burden of care of cancer patients has increased, so that all family members are now involved in care. We compared the health-related quality of life (HRQOL) between members of families of cancer patients (hereafter, cancer families) and members of cancer-free families (non-cancer families). Materials and Methods: The data were from the Community Health Survey (2012). The study population included respondents at least 30 years of age. Data were adjusted for the following covariates: sex, age, education, marital status, household income, economic activity, household type, chronic disease, and perceived health status. Frequency analysis, analyses of variance, and multiple linear regression analysis were performed. Results: Among 163,495 respondents, 3,406 (2.1%) were part of a cancer family and 160,089 (97.9%) were part of a non-cancer family. Cancer families had lower EQ-5D scores than non-cancer families. However, by subgroup, the scores had significant association between cancer and non-cancer families only for females and for those who worked. Conclusions: There was a significant relationship between HRQOL scores and being a family member of a cancer patient. This indicates that the responsibility for care has been extended to the entire family, not only the primary caregiver.

  • Purpose: This study was conducted to compare self-rated health, health status, and health promotion behaviors between non-low income and low income elderly women in the urban setting. Method: The subjects of this study consisted of 668 Korean elderly women over 65years. The data was analyzed by the SAS(ver.8.02) computer program, and it included descriptive statistics, ${\chi}^2-test$, analysis of covariance, pearson correlation coefficient and multivariate logistic regression. Results: 1) The non-low income elderly women had significantly higher scores(self-rated health, health status, and health promotion behavior) than the low income elderly women. 2) In low income elderly women, age, number of children were the main effect factors of health status, and level of education, burden of medical expense were the main effect factors of health promotion behaviors. In non-low income elderly women, number of children was the main effect factors of health status, and level of education, level of pocket money were the main effect factors of health promotion behaviors. Conclusion: This study showed that the establishment of a health care system for elderly according to their social-economic level is very important for providing productive care apposite to the situation of elderly.

  • Dispersion, migration and enrichment of environmental toxic elements from the Samkwang Au-Ag mine area were investigated based upon major, minor and rare earth element geochemistry. The Samkwang mine area composed mainly of Precambrian granitic gneiss. The mine had been mined for gold and silver, but closed in 1996. According to the X-ray powder diffraction, mineral composition of stream sediments and soils were partly variable mineralogy, which are composed of quartz, orthoclase, plagioclase, amphibole, muscovite, biotite and chlorite, respectively. Major element variations of the host granitic gneiss, stream sediments and soils of mining and non-mining drainage, indicate that those compositions are decrese $Al_2O_3$, $Fe_2O_3$, MgO, $TiO_2$, $P_2O_5$ and LOI with increasing $SiO_2$ respectively. Average compositional ranges (ppm) of minor and/or environmental toxic elements within those samples are revealed as As=<2-4500, Cd=<1-24, Cu=6-117, Sb=1-29, Pb=17-1377 and Zn=32-938, which are extremely high concentrations of sediments from the mining drainage (As=2006, Cd=l1, Cu=71, Pb=587 and Zn=481 ppm, respectively) than concentrations of the other samples and host granitic gneiss. Major elements (average enrichment index=6.53) in all samples are mostly enriched, excepting $SiO_2$, $Na_2O$ and $K_2O$, normalized by composition of host granitic gneiss. Rare earth element (average enrichment index=2.34) are enriched with the sediments from the mining drainage. Minor and/or environmental toxic elements within all samples on the basis of host rock were strongly enriched of all elements (especially As, Br, Cu, Pb and Zn), excepting Ba, Cr, Rb and Sr. Average enrichment index of trace elements in all samples is 15.55 (sediments of mining drainage=37.33). Potentially toxic elements (As, Cd, Cr, Cu, Ni, Pb, and Zn) of the samples revealed that average enrichment index is 46.10 (sediments of mining drainage=80.20, sediments of nonmining drainage=5.35, sediments of confluent drainage=20.22, subsurface soils of mining drainage=7.97 and subsurface soils of non-mining drainage=4.15). Sediments and soils of highly concentrated toxic elements are contained some pyrite, arsenopyrite, sphalerite, galena and goethite.

  • Due to the recent mid- to long-term slump and falling growth rates in the global economy, interest in organizational structures that create new products or services as a new alternative to survive and develop in an opaque environment both internally and externally, and enhance organizational sustainability through changes in production methods and business innovation is increasing day by day. In this atmosphere, we agree that the growth of small and medium-sized venture companies has a significant impact on the national economy, and various efforts are being made to enhance the technological innovation capabilities of the members so that these small and medium-sized venture companies can enhance and sustain their performance. The purpose of this study is also to investigate how the technological innovation capabilities of small and medium-sized venture companies correlate with the performance of knowledge management and to analyze the role of network capabilities to organize the strategic activities of enterprise to obtain the resources and organizational capabilities to be used for value creation from external networks. In other words, research was conducted on the impact of technological innovation capabilities of small and medium venture companies on knowledge management performance by using network capabilities as parameters. Therefore, in this study, we would like to verify the hypothesis that innovation capabilities will have a positive impact on knowledge management performance by using network capabilities of small and medium venture companies. Economic activities based on technological innovation capabilities should respond quickly to new changes in an environment where uncertainty has increased, and lead to macro-economic growth and development as well as overcoming long-term economic downturns so that they can become the nation's new growth engine as well as sustainable growth and survival of the organization. In addition, this study was conducted by setting the most important knowledge management performance within the organization as a dependent variable. As a result, R&D and learning capabilities among technological innovation capabilities have no impact on financial performance. In contrast, it was shown that corporate innovation activities have a positive impact on both financial and non-financial performance. The fact that non-financial factors such as quality and productivity improvement are identified in the management of small and medium-sized venture companies utilizing their technological innovation capabilities is contrary to a number of studies by those corporate innovation activities affect financial performance during prior research. The reason for this result is that research companies have been out of start-up companies for more than seven years, but sales are less than 10 billion won, and unlike start-up companies, R&D and learning capabilities have more positive effects on intangible non-financial performance than financial performance. Corporate innovation activities have been shown to have a positive (+) impact on both financial and non-financial performance, while R&D and learning capabilities have a positive (+) impact on financial performance by parameters of network capability. Corporate innovation activities have been shown to have no impact on both financial and non-financial performance, and R&D and learning capabilities have no impact on non-financial performance. It could be seen that the parameter effects of network competency are limited to when R&D and learning competencies are derived from quantitative financial performance. It could be seen that the parameter effects of network competency are limited to when R&D and learning competencies are derived from quantitative financial performance.

  • In geological $CO_2$ sequestration, the behavior of $CO_2$ within a reservoir can be characterized as two-phase flow in a porous media. For two phase flow, these processes include drainage, when a wetting fluid is displaced by a non-wetting fluid and imbibition, when a non-wetting fluid is displaced by a wetting fluid. In $CO_2$ sequestration, an understanding of drainage and imbibition processes and the resulting NW phase residual trapping are of critical importance to evaluate the impacts and efficiencies of these displacement process. This study aimed to observe migration and residual trapping of immiscible fluids in porous media via cyclic injection of drainage-imbibition. For this purpose, cyclic injection experiments by applying n-hexane and deionized water used as proxy fluid of $scCO_2$ and pore water were conducted in the two dimensional micromodel. The images from experiment were used to estimate the saturation and observed distribution of n-hexane and deionized water over the course drainage-imbibition cycles. Experimental results showed that n-hexane and deionized water are trapped by wettability, capillarity, dead end zone, entrapment and bypassing during $1^{st}$ drainage-imbibition cycle. Also, as cyclic injection proceeds, the flow path is simplified around the main flow path in the micromodel, and the saturation of injection fluid converges to remain constant. Experimental observation results can be used to predict the migration and distribution of $CO_2$ and pore water by reservoir environmental conditions and drainage-imbibition cycles.

  • This study analyzes the trend of the gender wage gap and its sources in the Korean labor market for the years 1985-2004. Following Oaxaca and Ransom (1994), the gender wage gap is composed of the productivity-related gap and non-productivity-related gap (unobserved productivity gap and discrimination). Empirical findings indicate that both the productivity-related gap and non-productivity-related gap have dwindled, while the decline of the former far excelled that of the latter. The non-productivity-related gender wage gap is much larger for married women than for single women, possibly implying a lower unobserved productivity of married women because of their childcare responsibilities. The non-productivity-related gap is also very substantial in the male-dominated occupations as compared to the female=dominated occupations, supporting the existence of network externalities in employment.

  • Since 2012, Prime Minister Shinzo Abe'sadministration began to promote women's participation and advancement in the workplace and established the Act on the Promotion of Female Participation and Career Advancement in the Workplace (the Act) in 2015. Some criticize this Act as a way to utilize women for economic development and to deal with the shrinking working population. In contrast, others point out that it is a law that can be beneficial for women. As such, this Act serves as an interesting case of a women's policy promoted by a conservative government. This paper's objective is to shed light on if and how women are substantively represented in the Diet members' statements made during the legislative debate of the bill on the Promotion of Female Participation and Career Advancement in the Workplace between 2014 and 2015. This paper asks two research questions. First, based on the mixed evaluation of the Act made in the studies about the Abe administration's women's policies, this research asks if the Diet members speak of women as resources to use for other economic and social goals or if women are substantively represented. Second, drawing insights from the literature on women's substantive representation, this research asks how Diet members speak for women. Particularly, based on the studies on conservatism and substantive representation of women, this question seeks to determine if Diet members engage in the conservative representation of women, taking women's roles as mothers and wives who provide care for children, husbands, and elders at home for granted. The results of the analysis demonstrate that the number of statements that explicitly claimed to use women was small. Second, while some Diet members of conservative political parties engaged in the conservative representation of women, there were more instances of non-conservative representation, in which a variety of types of women were represented. These findings reveal that even when the conservative government's intention to submit the bill was to utilize women rather than acting for women, Diet members could speak for various types of women and engage in the non-conservative representation of women. The findings also imply the importance of paying attention to formal and informal legislative deliberation rules to figure out how women's substantive representation can occur under a conservative government and in a legislature dominated by conservative parties.

  • A tentative hydrogeologic and hydrodispersive study was carried out to evaluate the groundwater pollution potential at a selected site by utilizing empirical assessment methodologies in an advanced stage of quantitative computer aided assessment. The upper most aquifer is defind as saturated overburden and weathered zone including the upper part of highly fractured rock. Representative hydraulic conductivity and storativity of the uppermost aquifer are estimated at 2.88 E-6 m/s and 0.09, respectively. Also calculated Darcian and average linear velocity of groundwater along the major pathway are 0.011 m/d and 0.12 m/d with average hydraulic gradient of 4.6% in the site. The results of empirical assessment methodologies indicate that 1) DRASTIC depicts that the site is situated on non-sensitive and non-vulnerable area. 2) Legrand numerical rating system shows that the probability of contamination and degree of acceptability are classed to "Maybe-Improbable, and Probable Acceptable and Marginally Unacceptable" with situation grade of "B". 3)Waste soil-site interaction matrix assessment categorizes that the study site is located on "Class-8 Site".
