This study analyzes the effects of department store loyalty programs on consumer relationship quality and the effects of consumer relationship quality on relationship continuity intention in department stores. The survey was conducted on women consumer patrons of department stores in October 2009; 381 responses were used in the data analysis. The statistical analysis methods were frequency analysis, factor analysis, reliability analysis, and multiple regression analysis. As a result, the loyalty programs of department stores were classified by the conformity, shared values, benefit of use, psychological availability, and convenience. The relationship quality of consumers was classified by trust and satisfaction, and the relationship continuity intention of consumers was classified by the continual use intention and word of mouth intention in department stores. The conformity, psychological availability, and convenience of loyalty program influenced the trust of consumers; in addition, the psychological availability influenced the satisfaction of consumers in department stores. The trust and satisfaction of consumers influenced the continual use intention and the satisfaction of consumers influenced the word of mouth intention in department stores.

In construction projects, it is common to exchange documents using email because of convenience. In this study, a method extracting and organizing block information automatically based on email was developed. This method is composed of document exchange and archiving processes, which are difficult to manage and vulnerable to loss. Therefore, this study aims to develop a solution that can automatically link email and block information. The block data components are designed to derive from email exchange and user-additional input information. Also, automatically generating blocks process including extraction and conversion of information was proposed. This solution can lead to promote the convenience of project document management in terms of identifying the document flow and preventing loss of information.

Until today, success in germline cells and tissue cryopreservation is limited mainly due to the poor understanding of the complex physiological processes can lead to cell damage during cryopreservation. Germline cells, from both male and female, have unique ability to differentiate into one or more cell lines and thus it becomes a crucial point to store them in subzero temperature with the minimal damage of their functional properties and maximum recovery of unchanged and viable cells when thawed. In the past three decades, a vast research has been performed using various different animal models which in fact have led to development of new methodologies and optimization of older one. However, successful use of animal model has provided the opportunity in research with human germline cells and tissues preservation, but not in all the cases. Therefore, the use of new cryo-protective chemicals and modified protocols have been often found in different groups of researchers based on the types, physical structures, utility and animal species of the specimens to be cryopreserved. This review discusses about the basics of different types of cryopreservation methodologies and commonly used optimized protocols and cryoprotectants for germline cells and tissues preservation.

Many researchers have employed cryopreserved amniotic membrane (CAM) in the treatment of a severely damaged cornea, using corneal epithelial cells cultured on an amniotic membrane (AM). In this study, two Teflon rings were made for culturing the cells on the LAM and CAM, and were then used to support the AM, which is referred to in this paper as an Ahn's AM supporter. The primary corneal epithelial cells were obtained from the limbus, using an ex-plantation method. The corneal epithelium could be reconstructed by culturing the third­passage corneal epithelial cells on the AM. A lyophilized amniotic membrane (LAM) has a higher rate of graft take, a longer shelf life, is easier to store, and safer, due to gamma irradiation, than a (AM. The corneal epithelium reconstructed on the LAM and (AM, supported by the two­Teflon rings, was similar to normal corneal epithelium. However, the advantages of the LAM over that of the (AM make the former more useful. The reconstruction model of the corneal epithelium, using AM, is considered as a good in vitro model for transplantation of cornel epithelium into patients with a severely damaged cornea.

The purpose of this study was to investigate the perception and utilization of salted seafood in Korean women. We also asked them about their opinions on how to increase the production range of popular salted seafood. Data were collected from 1,137 women and were analyzed with SAS 9.1 program. Women aged between 40 and 59 had higher positive perception of salted seafood than women aged between 20 and 39. The older age group (i.e. 40 to 59) believed that the production of salted seafood, such as like as Kimchi and soy sauce, should be globalized because of their taste and nutritional value. However, the younger age group (i.e. 20 to 39) had negative perceptions of salted seafood because of their unhygienic production and excess amount of salt. Women aged 50 and over used salted seafood frequently as a side dish or seasoning to make Kimchi, stew, or soup. The younger age group preferred to purchase a small package (200g or less) of salted seafoods from the grocery store instead of preparing it themselves. When purchasing salted seafood, they considered the taste, manufacturer, and expiration date. Finally, all interviewees agreed on the importance of salted seafood as part of traditional Korean cuisine, and wanted to see further local development. However, manufacturing and packaging processes need to be standardized, and hygiene and nutritional contents should be improved in order to achieve good quality local production. To succeed and develop high quality salted seafood, younger consumers need to be enticed with better nutritional value, taste, and hygienic production. Furthermore, the production range of popular salted seafood needs to be expanded beyond Kimchi and Soy Sauce. Hence new recipes are needed.

In this study, we analyzed the blood cadmium concentration in general population of Korea, and followed the analyses the relations with epidemiologic factors, life-style and body iron store. The geometric mean concentration of blood cadmium was 1.20 ${\mu}g/L$ in study subject, the level of blood cadmium was higher in female (1.27 ${\mu}g/L$) than in male (1.11 ${\mu}g/L$). The mean concentration of blood cadmium was the highest in coastal area (1.80 ${\mu}g/L$) and followed in urban (1.01 ${\mu}g/L$) and rural area (0.90 ${\mu}g/L$). The cadmium concentration in whole blood was increased with age-dependent pattern, such as 0.64 ${\mu}g/L$ in the below 30 years, 0.95 ${\mu}g/L$ in the 30~44 years, 1.28 ${\mu}g/L$ in the 45~59 years and 1.31 ${\mu}g/L$ in the over 60 years. The level of blood cadmium was higher in smokers than in non-smokers, but was not significant by alcoholic habit. The blood cadmium level was different from occupations, which was the highest in the fishers as 1.87 ${\mu}g/L$. The inversed relation was observed between blood cadmium and serum Fe, while was correlated positively with the ferritin level. In summary, the environmental exposure to cadmium in Korean is not so much compared to other countries, and the blood cadmium is influenced by genetic factors (age and sex), life-styles (dietary habit, occupation and smoking habit) and nutrition such as serum iron.
