Recent rapidly growth in nanotechnolgies is promised novel benefits through the exploitation of their unique industrial and biomedical applications. In addition, the production amount of these nanomaterials and nanoproducts has increased, and thus their uncontrolled release into the environment is anticipated to grow dramatically in future. Therefore, nanowaste streams must be effectively managed for sustainable nanotechnology. However, the effectiveness and capability of the current systems to handle nanowastes are yet to be established. In this review, we investigated several key topics for new paradigm of nanowaste treatment, (i) global and domestic production of nanomaterials and nanoproducts, (ii) definition and key resources of nanowaste, (iii) current and developing treatment method for nanowaste, and (iv) regulations for nanomaterials and nanoproducts.

The recent trend in tourism souvenirs has shifted from traditional products to modern, practical, and budget oriented products. As a result, tourism souvenirs that meet the changing demands of consumers need to be studied and developed. Aprons are one of the most important accessories worn for housework, and are also an important part of uniforms worn at restaurants and hotels. As a result, aprons typify the characteristics of makgeolli - practical products that meet the needs of modern consumers. Therefore, the development of tourism souvenirs targeting tourists that seek Jeonju Makgeolli is expected to bring substantial social and economic benefits. The purpose of the study is to develop designs for aprons for promotional and tourism souvenirs for the Jeonju Makgeolli Research Center. The research has been conducted with a survey on design preferences of aprons, design proposals, production of actual aprons, and selection of the final design. The study is empirical in nature and realistic in scope since it is anticipated that the trial and manufacture of aprons will be commercialized as tourism souvenirs. It is expected that aprons, which can be produced at low cost, will meet the needs of recent consumers who prefer elegant, modern, and practical goods as compared to simple and bland folk crafts or traditional products. More studies and research on the development of designs of aprons as tourism souvenirs is expected to be conducted based on this study.

Women’s experience of abortion are not only widespread but also significant event in their lives. But this experience has not been a concern for professional care by health care providers, especially nurses. As professional nurses should have holistic approaches to clients, need to understand the lived experience of abortion from women’s perspectives. These Nurses must identify unique means for improving the quality of life of women. This study identified the meaning and structure of the lived experience of abortion. The participants were residents of Seoul and Kwang ju who were recruited through personal recommendation. Colaizzi’s method was used for the phenomenological analysis. The research question was aimed at revealing the covert meaning of abortion. The 14 women who had a spontaneous abortion and /or an artificial abortion and who argeed to participate in the study were informed of the purpose of the study, the possible risks and benefits of participation, the data generation method and they were assured of privacy and confidentiality. The investigator conducted in-depth unstructured interviews which were audiotaped with the permission of the participants. The investigator read the data repeatdly to identify and categorize themes and basic structural elements. Eight themes of abortion as experienced by these participants were : 1) complicated feelings about the anticipated abortion 2) feelings of fear and anxiety about the operation and complications 3) grieving related loss and injury 4) feelings of lonliness in perceiving no supportive person, 5) attributing the cause of the abortion to siginificant others or to self, 6) guilt feelings and resentment, 7) vacillating between regretting and not regretting, 8) struggling to a responsible person. Five basic structures identified were : 1) Complicated feelings 2) Feelings of loss and need for caring 3) Attributings to cause to significant others 4) Paradoxical emotion 5) Struggling to be a responsible being The significes of this study for nursing are : 1) It enables nurses and other health care providers understand more clearly the lived experience of abortion 2) It provides information which can be used in for women who experience abortion.

This study examines work and family life of married women employed in a manufacturing industry. Data were gathered from the use of fact-to-face interview method from a sample of 230 married working women. The major findings of this study can be summarized as follows : (1) With high rates of change of job, most of the respondents remain unstable in their working situation. It was shown that the important factors influencing job satisfaction of married women are women's life cycle, degree of contribution of wife's income toward total family income, and husband's attitude toward wife's empolyment. The degree of job satisfaction is also strongly influenced by labor structural factors such as pay, work environment and fringe benefits. (2) The amount of household labor time was limited by job-related factors rather than by family-related factors, because among these working women employment itself is necessarily for their subsistance. (3) It was shown that wives participated more actively in their marital communications than their husbands. Most of the respondents showed the syncratic type of the decision making patterns, but this results does not necessarily mean wives exercised an equal power with their husbands. The economic factors and the emotional instability of the husband are the ones mostly influencing marital conflicts of the employed women. It was found that the respondents easily revealed marital conflicts related to personal problems of their husbands(such as extramarital affairs, gambling and alchoholism). However, they tried to overcome the structural conflicts related to authoritarian attitudes of their husbands or economic problems without any complaints. (4) Mothers have difficulty in controlling their adolescent children, due to the weakening of parental authority. Although most of the respondents perceived their employment as having negative impacts on their children, they still have high expectations toward their children. Inspite of low degree of father role expectations and facther role performance of their husbands, most of the respondents anticipated expressive roles as well as traditionally instrumental role from their husbands. Finally, these findings would help us determine family welfare policies in Korea. Improvements in paid and household labor structure of married women should be accomplished at the national level. Also, the acting programs for parent education, marital councelling services, and law enforcement for equal employment between men and women should be provided in our society.

Despite of growing concern for developing meteorological satellites, poor investment has been realized to acquire effective and efficient satellite image processing technologies. In this study, not only qualitative exploration on mapping each elementary technology into related industries but quantitative inter-industry analysis induced from Total Cost of Ownership (TCO) of the Korean satellite image processing system were performed. Furthermore, economic assessment has been made by estimating internal rate of return(IRR) for the benefits returned versus TCO of the system. The results showed that agriculture and fisheries industry, tourist and leisure industry, and transportation industry were highly related with the acquisition of the system, and that 9.1 billion won of production-induced effects, 3.3 billion won of value-added-induced effects, and 54 individuals of employment-induced effects were anticipated except for those of directly relevant industries. Even in the pessimistic scenario, 7% of IRR exceeding 5.5% assumed as current public rate was postulated, consequently, the investment was fairly justified.

Over the last few years, marine environment was found to be a source of surplus natural products and microorganisms with new bioactive secondary metabolites of interest which can divulge nutritional and biological impact on the host. This study aims to assess the possible, inherent and functional probiotic properties of a novel probiotic strain Enterococcus durans F3 (E. durans F3) isolated from the gut of fresh water fish Catla catla. Parameters for evaluating and describing the probiotics described in FAD/WHO guidelines were followed. E. durans F3 demonstrated affirmative results including simulated bile, acid and gastric juice tolerance with exhibited significant bactericidal effect against pathogens Staphylococcus aureus, Salmonella Typhi, Escherichia coli and Pseudomonas aeruginosa. This can be due to the enterocin produced by E. durans F3 strain, which was resolute by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) gel with amplification of the anticipated fragment of a structural gene; enterocin A, followed by antibiotic susceptibility assessment. Effective antioxidant potentiality against ${\alpha}$-diphenyl-${\alpha}$-picrylhydrazyl free radicals including lipase, bile salt hydrolase activity with auto-aggregation and cell surface hydrophobicity was similarly observed. Results are proving the potentiality of E. durans F3, which can also be used as probiotic starter culture in dairy industries for manufacturing new products that imparts health benefits to the host. Finding the potent and novel probiotic strains will also satisfy the current developing market demand for probiotics.

Ever since the definition "live microorganisms which when administered in adequate amounts confer a health benefit on the host"and guidelines of probiotics by the Food and Agriculture Organization of the United Nations and the WHO were announced, the research and product development using probiotics has been hugely successful. As a result, probiotics products become an important part of the functional food market. Recently, thanks to rapidly growing microbiome research, more diverse roles and health benefits of probiotics are being elucidated. Based on those results, pharmabiotics using probiotics are anticipated. In addition, in order to be internationally competitive and distributed, efforts should be made for certification such as GRAS/NDI notification through quality control that meets global standards. In this paper, we reviewed several aspects of probiotics concerning recently amended definition of probiotics, the regulation of probiotics, the strain specificity of efficacy, the association with microbiome research, and the market trends.
