The growth of food industry has not increased the demand for domestically produced agricultural products as raw materials. This is because the prices of domestic agricultural products are expensive relative to the imported ones and domestic products are hard to be supplied consistently. Thus the connection between domestic agriculture and food industry must begin with the investigation of appropriate items that have potentials to be used as raw materials for food industry. There have been many policies that support regional agriculture such as the policy that fosters regional cluster for agriculture. These policies can contribute to instigate the connection between agriculture and food industry. The infra prepared by the supporting policies and the facilities that food companies are operating can be used together for both agriculture and food industry. The complementary utilizations of the infra and facilities may encourage the connection between agriculture and food industry.

To estimate marine primary production, satellite data are essential for providing much better spatial and temporal resolutions. However, primary production estimation for turbid coastal water such as the Yellow Sea still needs much improvement. Here we evaluate currently available methods of primary production estimation in the Yellow Sea. We focus on comparison of eight combinations from four chlorophyll-a algorithms and two primary production algorithms of the Yellow Sea. Estimated primary production by the eight combinations ranged from 96.5 to $610.2\;gC\;m^{-2}\;yr^{-1}$ in the central region of the Yellow Sea. The new chlorophyll algorithms (presently under development by Korea, China, and Japan scientists) are expected to improve the retrieval of chlorophyll-a in turbid regions compared to the standard algorithm but there are certain unresolved problems. The new algorithm for primary production (which uses adjusted physiological parameters with in-situ data) also needs further improvement.

The effect of bisphenol S (BPS) on the viability and production of reactive oxygen species (ROS) was studied in boar sperm and ovarian granulosa cells. Boar semen was incubated in Beltsville thawing solution with either 0 or $5{\mu}M$ BPS for 3 and 6 h. The viability of sperm was analyzed by SYBR14/PI doubling staining, and production of ROS was detected. Ovarian granulosa cells were also treated with BPS for 24, 48, and 72 h. Then, cell viability (0, 5, 10, and $20{\mu}M$) and ROS production (only 0 and $5{\mu}M$ BPS) were assessed. The results showed that, BPS decreased sperm viability at 3 and 6 h, and that BPS increased ROS production (p<0.05). Also, BPS reduced the viability of ovarian granulosa cells (p<0.05), and stimulated ROS production (p<0.05). These results suggest that BPS damages sperm activation and ovarian granulosa cells in the reproductive system.

This study was conducted to evaluate the acceptability of cured cooked boneless chicken drumettes as a raw material for Chuncheon Dakgalbi and to observe its effect on pH, lipid oxidation, volatile basic nitrogen (VBN) content and total viable count (TVC) during refrigerated storage under vacuum. Boneless chicken drumettes were dry cured with a mixed curing agent (0.20% w/w) consisting of sodium chloride (93.1%), sodium nitrite (5.9%) and sodium bicarbonate (1.0%) for 24 h at $2{\pm}2^{\circ}C$. Cured samples were cooked using an oven at $150^{\circ}C$ for 20 min and stored at $5.5{\pm}0.5^{\circ}C$ for 60 days under vacuum. Non-cured cooked sample was used as a control. Sensory evaluation was performed on day 2 of storage using 22 untrained panelists and samples were mixed with Dakgalbi sauce and reheated using a microwave for 2 min. There were no significant differences between control and treatment group on appearance, flavor, texture, juiciness and overall acceptability. Cured cooked boneless chicken drumettes had significantly (p<0.05) higher pH, lower lipid oxidation, VBN and TVC consistently during storage in comparison with control. These results suggest that dry curing could be applied to boneless chicken drumettes as raw material for Chuncheon Dakgalbi and could extend its shelf life during refrigerated storage under vacuum.

The purpose of this study is to investigate the perception of buildings suspended from construction and to analyze the problems that are inherent and effective in the management of public officials and residents in the area where construction is suspended. There are 63 buildings in the Gangwon area, 16% of which are occupied by the whole area. 31% of the apartment houses are occupied the most, and 10 years or more is suspended. 241 of them accounted for 62%. In order to efficiently manage buildings that are suspended from construction, protection measures should be taken to ensure safety and prevent crime through periodic and continuous management of facility grade management that conforms to the special act on safety and maintenance of facilities. Effective support for budget and personnel is required for efficient management of construction suspended.

This study aims to examine the difference in the rurality of rural villages near a metropolitan city. It investigated the general status and economic activities of the two villages near Ulsan Metropolitan City to find out what the differences are and to diagnose the reasons for such differences and their impact on future changes in the villages. Through this survey analysis, it found that the two villages have been continuously experiencing a decrease in population over the last 10 years, despite being near large cities. In addition, it also identified the characteristics of the agricultural and livestock industries taking center stage in economic activities. In other words, although the cases are rural villages near a big city, it was shown that the village near a provincial city is basically based on agricultural characteristics. Regarding future prospects, on the one hand, in the case of Dagae-ri, the villagers expect that the current livestock industry-oriented activities may continue to develop. On the other hand, in the case of Shinhwa-ri, the residents think that the rural characteristics may be rapidly lost and urbanized. Based on these findings, this study suggests that rural policies for villages near large cities also need to be applied in a discriminatory manner, taking into account the basis on which economic activities in the villages are developed.

Foot-and-mouth disease (FMD) is a infection that can easily spread when it occurs and causes serious economic damage because of the existence of multiple serotypes of the virus and extreme contagiousness. The most effective method in preventing the transmission of FMD virus (FMDV) is the culling of livestock and additional vaccination in the other areas depending on the spreading rate and situation. Diagnostic methods are utilized not only for the definite diagnosis of FMD but also for identification of serotype, and confirmation of antibody production after vaccination. Although many methods have been developed to diagnose, they are not still enough to detect accurately the disease in a short time. Therefore, it has been needed new diagnostic methods improved from existing methods. Previous methods were based on the enzyme-linked immunosorbent assay (ELISA) as a serological diagnostic method, or polymerase chain reaction (PCR), which is a molecular genetic method. The recent technology has been performing about the combination of both methods and how to make it faster, less costly, more sensitive and accurate way.

The Purpose of this study is to understand phases and paradigms related to voluntary services offered by undergraduates and the processes in which voluntary services are implemented. For this, interviews for 23(men: 10, women: 13) undergraduates were conducted from Aug., 2008 to Apr., 2009 were conducted and the data collected from those interviews were analyzed on the basis of the Grounded Theory. Main analysis procedure is known as codings(open coding, axial coding, selective coding). This analyses produced 119 concepts, 41 subcategories, and 16 categories in open coding. Then, axial coding was conducted to organize the basic framework of generic relationships among psychological motivation, social context, personal perception, practical action, psychological response, and psychological consequence. Core essence is "Volunteer types are categorized simple practice type, self-serving type, and community type." Finally, undergraduate volunteers were explained in 3 types(simple practice, self-serving, and community) on the basis of paradigms. These results were discussed in terms of further research and limitation.
