The objective of this study was to investigate the polyphenolic compounds found in different parts of red and black adzuki beans and to determine the contribution of polyphenolic compounds to the antioxidant properties of adzuki beans. Total polyphenolic and proanthocyanidin contents were studied and their antioxidant activities were determined by ferric reducing antioxidant power, 1,1-diphenyl-2-picrylhydrazyl (DPPH), and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt assay. The highest total polyphenolic content was found in seed coats (26.1~33.9 mg/g), followed by whole beans (6.9~8.0 mg/g) and dehulled beans (3.3~3.4 mg/g). The highest total proanthocyanidin content was also found in seed coat with 26.5~30.7 mg/g. Moreover, seed coats exhibited the highest antioxidant activity regardless of analytical methods. Antioxidant activity was positively and significantly correlated with total polyphenolic content with the exception of dehulled beans, in which there was no correlation with total polyphenolic content. In particular, the highest correlation was found between DPPH and total polyphenolic content (r=0.945, P<0.01) in whole beans.

Organic waste, which is defined as wastes derived from various biological organisms that contain more than 40% of organic materials, is generated about 100 million tons per year in Korea. These organic wastes are now controlled by several governmental entities, under different rules and regulations, leading to the improper management and inefficient treatment. Therefore, integrated management system is primarily needed for the efficient recycling of organic waste. In this study, six kinds of organic wastes, which are food waste, sludges(sewage, waste water, night soil), animal excreta, animals and plants residues, and three kinds of recycling by-products(compost, feed, anaerobic digestion by-products) made of organic wastes, were analyzed for their physical and chemical characteristics. On the basis of this result, a possibility for the efficient recycling of organic waste was investigated.

While the legislation on the protection of personal information in public institutions was enacted and amended, the guidelines and laws on information security were focused, contracted and realized with focus on specific institutions. Mutual laws and guidelines have been applied and realized for the dual purpose of securing both the asset of macroscopic information and the asset of personally identification information, which are mutually different media information. However, in a bid to present the definition and direction of the fourth industrial revolution in 2017, a variety of products and solutions for security designed to ensure the best safety line of the 21st century, and the third technology with the comprehensive coverage for all these fields, a number of solutions and technologies, including IOT(: Internet of Things), ICT Internet of Things(: ICT), ICT Cloud, and AI (: Artificial Intelligence) are pouring into the security market as if plastic doll toys were manufactured in massive scale into the market. With the rising need for guaranteeing the interrelation for securities with dualistic physical, administrative, logical and psychological differences, that is, information security and personal information security that are classified into two main categories and for the enhanced security for integrated management and technical application, the study aims to acquire the optimal security by analyzing the interrelationship between the two cases and applying it to the study results.

Illustrations in advertisement uses various social and cultural codes to stimulate the desire to buy in consumers in the first place, since this is an economic phenomenon orchestrated to sell a product. Hence, factors outside the product per se, such as tradition, social issues and class consciousness are introduced. Especially, in modern advertisement a strategy is adopted to differentiate standard products produced by mass production. In order to do so, such factors as mentioned above become as important as physical characteristics of the product per se and its usage value. As a result, phrases or images used for advertisement can have independent influences on the society irrespective of the sales effects on the product. In this respect, it is fair to state that advertisement reflects the phases and consciousness of a given period as a cultural phenomenon. Therefore, based on the premise of characteristics and roles attributed to the advertisement, this thesis proposes to make a comparative study on the images of women in commercial advertisement in Korea during Japanese Imperialism and China during Cultural Colonial period dating from 1900 to 1945. The starting point of this research will cover the period of foreign trade and Japanese Imperialism in Korea and interference of Western Power in China. It will also investigate on the birth of Korean advertisement by Japanese Imperialists and Chinese modern advertisement along with the modernization of Shanghai. Then, I propose to present the illustrations of women in advertisements based on comparative study of their characteristics and expressions as observed in several case studies both in Korea and China. Connotative meanings in such advertisement will be investigated in the context of political, economic and cultural dominance.

The main purpose of this study is to figure out the spending tendency of elderly consumers for their grandchildren. To this end, a detailed survey was carried out for two months from October 1 to November 30, 2011. The respondents consist of 461 elderly consumers over 60s who have grandchildren in elementary grades. Among the gathered data, relevant information was sorted out, coded, and then turned into statistical figures through SPSS 18.0 program. The outcome of this research is explained in the following three respects. First of all, based upon factor and cluster analysis, the role of grandparents has been divided into three categories, which are a babysitter, a friend and a visitor. Depending on their role, the surveyed elderly have been split into three groups-'Friend Group', 'Formal Visitor Group', 'Attached Group'. Second, to give you an overview of the consumption trend of the three groups, this study has reviewed the expenditure items, spending amount and consumption patterns, and made a list of products and services they purchased for the past one year for their grandchildren. Third, given the probability of wealth transfer to the next generation, there is a compelling need to figure out the purchase pattern of financial products. The elderly have been categorized into those with bank deposits only and those with a mixture of bank deposits and other financial products (insurance, fund, stocks, gold, dollar etc.).

The paper presents results of qualitative analysis of non-regulated organic pollutants in municipal wastewater and treated municipal wastewater with flocculation, ozone and UV process using GC-MS. The majority of the pollutants in the influent of the municipal wastewater treatment facility were either food related or due to the diffuse discharge from products used both in households and in industry. In the case of biological treatment process removed some organic pollutants effectively. But some organic pollutants were not removed with biological treatment. Thus, additional steps to improve the quality of effluent municipal wastewater will require a more rigorous control of consumer products used in household and municipal wastewater process using advanced treatment processs. The obtained data contributed to the evaluation of pollutants discharges to the ecosystem as well as to the characterization of pollution sources in the basin.

In accordance with the amendment of the Industrial Safety and Health Act of 2007, Korea completely prohibited the import, distribution and manufacture of asbestos like Europe and Japan. Accordingly, the current problem of asbestos is the safe maintenance and disposal of asbestos construction material, the disposal of asbestos, and the final disposal of asbestos building materials. If the asbestos building material is made harmless, it may be classified as general waste or as recyclable waste. Therefore, this study evaluated the physical and chemical characterization of detoxified asbestos powder and the applicability of secondary products. In this study, it was found that applying the appropriate temperature and pressure for catalysis during asbestos desalination through low temperature chemical treatment was the most important factor.

In an effort to characterize the physicochemical properties and microbial risks associated with the soy sauce jangachi (Korean traditional pickle), 15 different home-made products, which were prepared from medicinal plants and wild edible vegetables, from head-families of Andong, Kyungsangbuk-do Province in Korea, and 6 different commercial products sold at supermarket, were investigated. The average pH of the mature soaking solutions and plants soaked in the 21 jangachi were $3.99{\pm}0.38$ and $3.51{\pm}0.41$, and the average acidity of the mature soaking solutions and soaked plants were $1.59{\pm}0.54$ and $1.65{\pm}0.76$, respectively. The average brix of the mature soaking solutions and plants soaked were $27.67{\pm}8.38$ and $25.61{\pm}6.60$, respectively. In salinity, which is a major factor in jangachi industry production, the average salinity of the mature soaking solutions and soaked plants were $7.55{\pm}3.26$ and $5.75{\pm}2.23$, respectively. In particular, the hot-peppers, eusuri, du-rup, kaet-ip, kuji-ppong, myeng-i and sancho jangachi were amongst the home-made products, and the salinity was above 8.8%, which was 2 folds-higher than that of the commercial sterilized products, and 1/3-lower than commercial non-sterilized products. The color difference and turbidity of jangachi were dependent on the plant parts used. In microbial risk assessment, the microorganisms related with food-borne disease, such as Escherichia coli, Salmonella sp, and Shigella sp., were not detected. After some time, total cell count analysis revealed that the commercial products sold at supermarkets were more vulnerable than the home-made products.

This study investigated the microbial contamination levels of raw meats used for short-ripened salami and changes in the microbial and physico-chemical properties of the product during storage at 10 and $25^{\circ}C$ for up to 120 days. The microbial counts of raw meats ranged between 2 and 4 Log CFU/g. Frozen-thawed sow meat showed higher total aerobe and Enterobacteriaceae counts than fresh chilled pork and pork back fat. Staphylococcus aureus was found in all raw materials except fresh chilled pork samples, and Clostridium perfringens was detected in a sample stored for 21 days at $25^{\circ}C$. The counts of total aerobes, lactic acid bacteria and Staphylococcus spp. decreased more rapidly at $25^{\circ}C$ than at $10^{\circ}C$ when the storage time was extended. The growth of Enterobacteriaceae, Pseudomonas spp., Clostridium spp., yeast, and mold were restricted to levels below 2 Log CFU/g during storage. The contents of salt, water, crude protein, crude fat, and ash of salami samples were 3.4, 33.4, 30.8, 32.7, and 4.3%, respectively, which were not affected by storage time or temperature. The pH value of the salami was initially 4.79 and increased to 5.02 and 5.26 after 120 days of storage at 10 and $25^{\circ}C$, respectively, whereas the water activity values decreased from an initial value of 0.91 to 0.90 and 0.88 after 120 days at 10 and $25^{\circ}C$, respectively. The TBA and VBN values increased slowly during storage. The redness value of the salami samples stored at $25^{\circ}C$ decreased more significantly than the samples stored at $10^{\circ}C$. With increased storage time, the values for the rheological characteristics of the salami in terms of hardness, brittleness, elasticity, cohesiveness, gumminess, and adhesiveness tended to decrease more remarkably at $25^{\circ}C$ than at $10^{\circ}C$. Based on sensory evaluation scores, it appears that short-ripened salami is no longer acceptable after 90 days at $10^{\circ}C$ and 30 days at $25^{\circ}C$.

Tidal flats have been regarded to carry out transformation and removal of land-derived organic matter, and this purifying capability of organic matter by tidal flats is one of very important reasons for their conservation. However, integral biogeochemical studies on production and decomposition of organic matter by benthic microbes in tidal flats have been absent in Korea, although the information is indispensable to quantification of the purifying capability. Our major goals in this multidisciplinary research were to understand major biogeochemical processes and rates mediated by diverse groups of microbes dominating material cycles in the tidal flats, and to assess the contribution of benthic microbes to removal of organic matter and nutrients in the tidal flats. Our study sites were Ganghwa and Incheon north-port tidal flats that had been regarded as naturally well reserved and organically polluted, respectively. Our research group measured over 3 years primary production, biomass and community structure of primary producers, abundance and production of bacteria, enzyme activities, distribution of protozoa and protozoan grazing rates, rates of denitrification and sulfate reduction, early sediment diagenesis, primary production and respiration based on oxygen microelectrode. We analyzed major features of each biogeochemical process and their interactions. The results are compiled in the following articles in this special issue: An (2005), Hwang and Cho (2005), Mok et at. (2005), Na and Lee (2005), Yang et at. (2005), and Yoo and Choi (2005).
