Unusually severe rice blast epidemic sweeped over the rice growing area in Gyeongnam Province and elsewhere in 1993. Leaf blast infection was reached to 33,133 ha, which is about 24.5% of total paddy area and neck blast infection was apparent throughout 4,421 ha. Major factors affecting such an unusual epidemic appeared to be as follow: Firstly, low temperature, frequent rainfall and coincidentally insufficient duration of sunshine through July and August; Secondly, most cultivars possessing low levels of field resistance were cultivated in wide areas: Thirdly, blast fungus population was enough for successive infection under optimum weather condition and most races distributed in field were able to infect most cultivars.

Purpose: In this study, we try to figure out the appropriate size of commercial districts in the original downtown area through empirical studies targeting the Jinju Central Commercial Area in Gyeongnam and Cheonan Station in Chungnam, which are trying to regenerate a specific space that has been lost through government projects. Research design, data and methodology: The current status and characteristics of the shopping district were examined through on-site surveys of the central business district of Jinju, Gyeongnam Province, and Cheonan Station, Chungnam Province, and the size of the empty stores was determined. In addition, the standard median income was used as the survey data along with the survey of the mobile population in the commercial area. Result: The analysis result shows that 883 stores should be maintained considering the overall expenditure and gross sales profit within Cheonan Station in South Chungcheong Province. Currently, considering spending and margins in the Commercial Area, Jinju Central Commercial Area is a place where 222 stores can be sold excessively, and a proper commercial supply plan is needed. Conclusions: In this study, we conducted a demand prediction study in the commercial sector of the most basic sector to regenerate the commercial sector through major regional commercial districts.

This survey was conducted to obtain basic data about organic matter such as BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), DOC (Dissolved Organic Carbon) and TOC (Total Organic Carbon) in agricultural water in Gyeongnam province. BOD and COD are currently used for water quality indices, but adoption of TOC is being suggested. The surface water samples were collected at 39 locations in Gyeongnam province in April, July and October. Average concentrations of BOD, COD, DOC and TOC were 1.6, 3.3, 5.3 and $5.7mg\;L^{-1}$, respectively. In July, average concentrations of BOD and COD were 2.4 and $3.9mg\;L^{-1}$, respectively, showing these values were higher than other months. Average concentrations of TOC in April, July and October were 4.8, 7.4 and $4.8mg\;L^{-1}$, respectively. This suggested that the highest value of TOC was in July. Average decomposition efficiencies for BOD-C/TOC and COD-C/TOC were 11.4 and 23.9%, respectively. Correlation coefficient of TOC and DOC was higher by 0.995, whereas that of TOC and COD was lower by 0.763. Especially, TOC and DOC were highly related than others.

Pressed ham was manufactured to investigate the effects of grape seed oil on the quality characteristics of pressed ham. Five treatments were divided based on differences in the amount of grape seed oil added into the pressed ham. For control, 10% of back fat was only added without grape seed oil. For the first treatment, 10% of grape seed oil among the lard component added into the pressed ham was replaced. For the 2nd, 3rd and 4rd treatments, 20%, 30% and 40% of grape seed oil was respectively replaced. Pressed ham manufactured using grape seed oil was vacuum packaged and then stored for 1, 7, 14, 21 and 28 days at 4℃. Samples were analyzed for shear force value, sensory properties, TBARS and fatty acid composition. In the 1, 21 and 28 days of storage, shear force value of grape seed oil treatment (T4) was significantly lower than that of control (P<0.05). No remarkable differences were found in sensory properties among control and grape seed oil treatment groups. The TBARS value was significantly higher in control than in grape seed oil treatment group(T4) at 28 days of storage (P<0.05). The TBARS of control and grape seed oil treatment groups increased significantly as the storage period increased(P<0.05). The linoleic acid(C18:2) content of grape seed oil treatment groups was significantly higher than that of control(P<0.05). But the contents of C10:0～C20:4 were decreased significantly by grape seed oil additive (P<0.05). Saturated and monounsaturated fatty acid content of control was significantly higher than that of grape seed oil treatment groups(P<0.05). Whereas the increase level of grape seed oil additive resulted in the significantly higher polyunsaturated fatty acid content(P<0.05). Based on these findings, we conclude that the sensory properties and lipid oxidation(TBARS) of manufactured pressed ham were not affected by grape seed oil addition. Also, our results indicate that high-quality pressed ham can be manufactured with strengthen of polyunsaturated fatty acid content.

The effects of olive oil on the quality characteristics of pressed ham were investigated. Five different treatments were carried out varying the amount of olive oil added to pressed ham. for the control, 10% back fat among the total ham components was added without any olive oil. For the first treatment, 5% olive oil within the lard component was added into the pressed ham. The 2nd, 3rd and 4th treatments included 10%, 15% and 20% olive oil, respectively. Manufactured pressed hams containing olive oil were vacuum packaged and then stored for 28 days at $4^{\circ}C$. The crude protein and crude fat were not significantly different between the control and olive oil treated hams. The moisture and crude ash contents of olive oil treated hams was significantly lower than that of the control(p<0.05). There was no significant difference in pH between the control and olive oil treated hams. The pH increased during the first 7 days of storage and then decreased somewhat for the remainder of the 28 day storage period for all treatments. The meat color $b^*$ value of olive oil treated hams was higher than that of the control, whereas the meat color $a^*$ value decreased with the inclusion of olive oil. Neither value changed during the period of storage. There was no significant difference in texture between the control and olive oil treated hams throughout the storage period. In summary, pressed ham manufactured with added olive oil showed no change in physico-chemical properties and texture characteristics. Thus, it may be assumed that high quality pressed ham can be manufactured with increased monounsaturated fatty acid content.

Conjugated linoleic acid (CLA) was chemically synthesized using the alkaline isomerization method of com oil. CLA-TG was synthesized by reaction with sodium methoxide. Five different treatments were devised based on differences in the amount of CLA-TG added into the pressed han. for controls, 10% of pork back fat among the total component was only added without any CLA-TG. For the first treatment, 5% of CLA-TG among the lard component added into the press ham was replaced. For the 2nd, 3rd and 4th treatments, 10%, 15% and 20% of CLA-TG was respectively replaced. Pressed ham manufactured using CLA-TG was vacuum packaged and then stored for 1, 7, 14, 21 and 28 days at $4^{\circ}C$. Samples were analyzed for chemical composition, physico-chemical properties (pH, color), and texture characteristics. Typical chemical composition characteristics (moisture, crude protein, crude fat) were not significantly different between controls and CLA-TG treatment groups. Crude fat content of CLA-TG treatment groups was significantly lower than that of controls (p<0.05). pH values of controls was higher than that of CLA-TG treatment groups. The pH of control and CLA-TG treatment groups increased significantly as the storage period increased (p<0.05). Meat color (CIE $L^*,\;b^*$) of CLA-TG treatment groups was higher than that of controls. $a^*$ values were decreased by replacement of CLA-TG, but appeared to be unaffected by storage length. There was no significant difference in texture between controls and CLA-TG treatment groups. Based on these findings, we conclude that the physico-chemical properties and texture characteristics of manufactured pressed ham were not affected by CLA-TG addition. Also, our results indicate that high-quality pressed ham can be manufactured with CLA accumulation.
