Relationship Marketing has been dealt with as an effective strategy to sustain customer loyalty in many previous researches. For relationship development, a customer's efforts are necessary as well as an organization's efforts. However, the role of customers for the development of the relationship with an organization has been dealt in few previous researches so far. Furthermore, whereas researchers understand the importance of consumers' motivation in the relationship, few researchers had paid attention. This research is based on the Self-Determination Theory (SDT) to explain the role of customer motivation in the process of relationship development and performance. We started by using SDT to confirm the psychological side of relationship development in customer aspects. Then, this paper verified the relationships among environmental factors(informative communication, perceived personalization), relationship motivation(identified motivation, internal motivation) and relational factors(affective commitment, relationship strength). It suggested that customer's roles in psychological parts be inevitable in developing the relationship and it acquired by such stimulations from service providers. In conclusion, this paper has several marketing implications on customer acquisition and retention. For service providers, they should recognize the fact that a customer's perception of self-determination factors can generate tangible and intangible performance in relationship development.

Concentrations of selected heavy metals (Al, Fe, Mn, Cr, Cu, Ni, Zn, Pb, As and Cd) in surface sediments from 96 sites in Masan and Jinhae Bay were studied in order to understand metal contamination. Results show that the surface sediments were mainly enriched by Cu (18-294 ppm), Zn (67-568 ppm), Pb (10-120 ppm) and Cd (0.2-3.5 ppm). The coastal zone of Masan Bay was significantly more contaminated than the non-coastal zone, and spatial distribution pattern suggested additional sources of heavy metal input in the coastal area. The enrichment ratio and geoaccumulation index ($I_{geo}$) have been calculated and the relative contamination levels assessed in the study area. The enrichment ratios of Cu, Zn, Pb and Cd in Masan Bay have been observed to be relatively high. $I_{geo}$ results reveal that the study area is not contaminated with respect to Fe, Mn, Cr and Ni; moderately to strongly contaminated with Cu, Zn and Pb; and strongly to strong contaminated with Cd. The high contents of Cu, Zn, Pb and Cd in the study area result from anthropogenic activities in the catchment area. Based on the eight different sediment quality guideline values from USA (ERL, ERM), Canada (TEL, PEL), Australia/New Zealand (ISQG-high, ISQG-low) and Hong Kong (ISQV-low, ISQV-high), sediment quality of Masan and Jinhae Bay was also assessed and characterized.

Spatio-temporal patterns in the zooplankton communities, physicochemical environmental factors, and dominant species were examined in Camak Bay from April, July, September, and November, 2003. A total of 40 taxa were sampled with a mean abundance of total zooplankton ranging from $270{\sim}1,803inds/m^3$. The most abundant species was Acartia erythraea, followed by Eurytemora pacifica, Podon polyphemoides, A. omorii, and Paracalanus parvus s. 1 during the study period. Multivariate analysis revealed significant differences in community structure among three regions: the middle part of the sampling area (B), sites 1, 2 (A) and other sites (C). The number of species and diversity (H') varied significantly among the three regions (p<0.05), but no differences in the mean abundances were observed (p>0.05). In order to investigate factors affecting the correlations between the abundance of dominant species, all zooplankton and environmental factors ware calculated using a correlation analysis. Of these, the abundance of dominant taxon showed positive correlation with seawater temperature, salinity and dissolved oxygen (p<0.05). In statistical analysis showed that the environmental factors influencing the variation of the communities ere predominantly temperature, salinity, and dissolved oxygen.

With the rapid growth of Chinese economy, environmental issues also became a serious problem that public and private sector have to take under consideration. For the sustainable growth of Chinese economy scholars and policy makers agree to the stronger regulation for protection of natural environment, but at the same time worry about its negative effect on economic growth. This paper primarily focus on the relationship between the factors that have the effect on green product purchasing intention and purchasing behavior. Purchasing intention was considered as mediating variable in our model and state-action orientation - as moderating variable. We set 8 hypotheses and tested with structural equation modeling. The result shows that governmental regulation and subsidy, social environment related with green product purchase, and consumer perception on the benefit of green product have positive relationship with purchasing intention, but environmental concern does not show relationship with it. We also proved that state-action orientation has moderating effect between purchasing intention and purchasing behavior. Purchasing intention with action orientation show positive and statistically significant effect on purchasing behavior. This result supports the hypothesis that the attitude of customers has the effect on ones purchasing behavior.

Fish community was investigated in eutrophic Jeondae agricultural reservoir from April to November 2012. The food web structure of major fish species of Jeondae reservoir showed that due to serious organic pollution, the hyper-eutrophic condition with high chemical oxygen demand (COD), chlorophyll-a (Chl-a), total nitrogen (TN) and total phosphorus (TP), as estimated by stable isotope analysis. Total of 679 individuals were collected from the reservoir, and 9 species were identified. Interestingly, Lepomis macrochirus and Hemiculter eigenmanni known as less sensitive to pollution and water quality deterioration, dominated the reservoir, and their relative abundances were 38% and 27%, respectively. Further, the analysis of the stomach contents revealed that main food source of dominant L. macrochirus was high amount of zooplankton, which includes copepoda and cladocera, while Cyprinidae species mainly consumed organic particles with zooplankton preys. Stable isotope analysis also suggested that L. macrochirus, Carassiusauratus, Pseudorasboraparva, and H. eigenmanni are major zooplantivorous group in the Jeondae Reservoir.

The Okbang amphibolites occurring as sill-shaped bodies within the Precambrian Wonnam Group have been studied in terms of geochemical characteristics for their tectonomagmatic environments. The amphibolites fall in the ortho-amphibolite fields in Ni and Cr versus Cu diagrams. They belong to subalkaline and tholeiitic series in total alkali versus silica and ternary AFM diagrams, respectively. They show the compositional variation corresponding to the differentiation trend of tholeiitic suites. In discrimination diagrams using high-field-strength elements such as Ti, Zr, Nb and Y, the amphibolites show geochemical affinities to both of volcanic-arc tholeiites and normal (depleted) mid-oceanic ridge tholeiites. The REE patterns of the amphibolites are nearly flat and extremely similar to those of back-arc tholeiites. $(La/Yb)_{CN}$ ratios vary from 0.89 to 2.02 with an average value of 1.23. Such low light-REE abundances in the amphibolites suggest that they were derived from the upper mantle source depleted in these elements. In view of geochemical characteristics showing strong enrichments of incompatible elements such as K and Rb, distinctive negative Nb anomalies, depletions of light-REE observed also in normal (depleted) mid-oceanic ridge tholeiites, and unfractionated immobile elements such as Y and Yb, the tholeiitic magmas, from which the parent rocks of the amphibolites were formed, would be generated from a depleted upper mantle source and contaminated by continental crustal materials en route to surface. Tectonomagmatic environment for the amphibolites can be assumed to be continental back-arc basin.

The purpose of this study is to understand the effect of physical environment of family restaurant upon customers' emotions, satisfaction and revisit intent. Based on total 438 samples obtained from the empirical research, this study reviewed the reliability and fitness of the research model using Amos program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model (SEM). The proposed model provided an adequate fit to the data, $x^2$ 592.898(p<0.001), df=239, CMIN/DF 2.481, RMR 0.103, GFI 0.900, NFI 0.952, CFI 0.970, RMSEA 0.058. SEM resulted that the physical environment showed a significant effect on customers' positive emotions($\beta$=0.388, p<0.001) and negative emotions($\beta$=-0.148, p<0.001). Also, customers' positive emotion($\beta$=0.828, p<0.001) bad a positive significant effect on customer satisfaction, and customer satisfaction($\beta$=0.771, p<0.001) bad a positive significant effect on revisit intent. Limitations and future research directions are also discussed.

We investigates geochemical and tectonic characteristics for the Triassic Bojangsan trachyte in the southern margin of the Imjingang belt. The geochemical signatures of the thracyte are characterized by enrichments of REE and HFS, and show no Nb trough, suggesting that would not experience arc magmatic processes involving continental crustal materials. The trachyte reveals within-plate setting in tectonic discrimination diagrams using immobile HFS Nb and Y elements. And the trachyte shows typical signatures of A-type volcanic rocks with high Ga abundance and is classified as A1-type volcanic rocks rich in Nb. The geochemical signatures suggest that the trachyte was produced by the differentiation of mantle-derived magmatism at the continental rift in extensional setting subsequent to a major collision during the Permo-Triassic Songrim orogeny. The results provide robust evodence to consider the Imjingang belt as an extension of the the Qinling-Dabie-Sulu belt between the North and South China blocks.

This study intended to examine the effects of each factor on teacher efficacy. A questionnaire survey was administered on 225 home economics teachers in middle school in Gyeonggi-do, and a total of 194 copies of the questionnaire excluding poorly filled-out 31 copies were used for the final analysis. A questionnaire in a self-administering design was used to collect data on individual characteristics, teacher efficacy, self-esteem, development of expertise, and educational environment of school perceived by the middle school home economics teachers. The findings of this study are summarized as follows; First, there were significant differences in teacher efficacy according to age, education and service years. Second, significant differences were found in teacher efficacy according to self-esteem, development of expertise and educational environment of school. That is, the more positive self-esteem, development of expertise, participation of parents, characteristics of students and other teachers, and teachers' perception about teaching-learning aids were, the higher home economics teachers' efficacy became. Third, the study revealed that teacher efficacy was influenced by development of expertise, educational environment of school and self-esteem. Considering these results, positive self-esteem of teachers, practical teacher training, expansion of self-development training opportunity, aids from educational authorities in terms of money and time are needed to improve teacher efficacy of home economics teachers. Efforts should be made to help teachers have positive attitudes toward parents, students, and other teachers.
