This study explores the life quality(LQ) of Korean married women compared to Korean married men's LQ, examines personal factors' and home environmental factors' influences to Korean married women's LQ via psychological factors such as social belongingness, positive emotion, self-esteem, and sense of intemal control in causal model, and explores Korean married women's perceived important factors and perceived enhancement required factors in life. The questionnaire was administered to 941 Korean married women and their husbands who have one or more children in Pusan. The results indicated that: 1. The overal and most sub dimensional LQ of Korean married women mark medium level and were lower than that of Korean married men's. Korean married women who is highly educated, keeps efficient communication with their husband, self-esteem, sense of internal control, social belongingness, and positive emotion, and possess high SES and much available resources shows higher LQ than those who doesn't. 2. The efficient communication with husband and available resources have direct and indirect influences on Korean married women's LQ. The psychological mediatory factors of these two variables' influences on women's LQ are such as social belongingness, positive emotion, self-esteem and sense of intemal control. SES has direct influence only and the educational level has indirect influence via social belongingness only on Korean married women's LQ. All these factors explain 58% of Korean married women's LQ variance. 3. Korean married women rank family health, family reconciliation, husband's success, and children's achievement as the very important factors in life. They also rank husbands success, economic abundant, family reconciliation, family health, and their self-actualization as the very required factors for enhancing the given LQ.

The purposes of this study were to prolong the storage period and maintain quality of kimchi made from spring napa cabbage, which is used less frequently than winter napa cabbage. The results show that the firmness of kimchi from early July, the latest harvest period, was significantly higher than that of kimchi from mid-June. However, as maturation proceeded, no significant difference was observed following the harvest period when kimchi was stored for 8 weeks. Regarding pH and acidity, which are highly related to maturation of kimchi, pH generally decreased from the initial storage period while acidity increased. In the sensory evaluation, appearance was best in kimchi manufactured in late June according to manufacturing and maturation periods (p<0.05). After 4 and 8 weeks of storage, kimchi manufactured in early July had the highest scores with no significant difference. Texture and overall acceptability also showed no significant difference in each processing period.

In this study, the antibacterial activities of essential oil from Zanthoxylum schinifolium against four Gram-positive bacteria and six Gram-negative bacteria were investigated. The antibacterial activity of the oils was determined using the agar-well diffusion assay, MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration). In particular, essential oil from Z. schinifolium showed higher antibacterial activity against Gram-positive bacteria than against Gram-negative bacteria. Essential oil from Z. schinifolium displayed large inhibition zones especially against Bacillus cereus (31 mm). At concentrations between 0 and $20\;{\mu}g/mL$ the oils showed an antibacterial effect against both Gram-negative and Gram-positive bacteria. The minimum inhibitory concentration (MIC) values against nine bacteria ranged from 1.25 to $5\;{\mu}g/mL$. The minimum bactericidal concentration (MBC) values against eight bacterial ranged from 2.5 to $20\;{\mu}g/mL$, except Shigella sonnei. Furthermore, our finding on the antibacterial activities of essential oils from Zanthoxylum schinifolium validated the use of this plant for medical purposes.

As part of a larger study with the aim to discover indigenous prokaryotic species in Korea, nine bacterial strains were isolated and assigned to the phylum Proteobacteria in 2016. High 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clades with known species indicated that each strain belongs to an independent and predefined bacterial species. This is the first report of these nine species in Korea: two strains of the Methylobacterium, two strains of the Microvirga, one strain of the Pantoea, and four strains of the Psychrobacter, all within the Proteobacteria. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

The objectives of this study were: a) to classify rural women's roles according to apicultural activity, and b) to find out the needs for education system related to women's roles in agricultural technology and the participation in decision making of farming activities, and c) to put forward the programs in agricultural educational system for supporting rural women according to their role types. This study was based on a literature review, empirical analysis including women in rural Korea. Based on the empirical findings, the following suggestions could be of offered for helping the rural women according to the types of their roles. 1) Family cultural reform, farming helper system, relief of housework allotment, supporting educational expenses, equal opportunity and easier places for participations should be strengthened in education programs of women farmers in Korea. 2) Government should provide diverse incentive programs, appropriate information and educational supports for women farmers' agricultural education including equipment and facilities for easy farm management. 3) Automation and mechanization of farm works, computer education, eco-friendly agricultural production skills, family consciousness and group action, importance and the future prospects of agriculture and farming, leadership role should be strengthened in agricultural education programs for rural women.

This study attempted to establish the optimal conditions for storage of spring kimchi cabbage to stably control supply and demand. To this end, this study stored kimchi cabbages in various manners for different periods and compared the quality characteristics of kimchi using these cabbages. According to the results, pre-drying with photocatalytic and pre-cooling treatments showed average selectivity loss rates of 18.83 and 21.37%, respectively, which were lower than those of other treatments. Spring kimchi cabbages were stored for 15 weeks under various conditions, and the kimchi was stored for 4 weeks at $4^{\circ}C$. After ripening, each kimchi was analyzed for their soluble solid content, pH, acidity, and salinity. The average pH of kimchi was 4.60 and tended to rise, whereas average acidity was 0.38% and fell by 0.24 to 0.31% as the storage period was extended. Extension of the storage period caused decreases in soluble solid content and salinity, and the number of lactic acid bacteria decreased due to increased pH and reduced acidity (p<0.05). Sensory evaluation showed that all experts and non-professionals preferred kimchi treated by precooling compared to any other treatment.

The objective of this study was to determine the minimum enrichment time for different types of food matrix (pork, beef, and fresh-cut lettuce) in an effort to improve Escherichia coli detection efficiency. Fresh pork (20 g), beef (20 g), and fresh-cut lettuce (20 g) were inoculated at 1, 2, and 3 Log CFU/g of Escherichia coli. Samples were enriched in filter bags for 3 or 5 h at $44.5^{\circ}C$, depending on sample type. E. coli cell counts in the samples were enriched in E. coli (EC) broth at 3 or 5 h. One milliliter of the enriched culture medium was used for DNA extraction, and PCR assays were performed using primers specific for uidA gene. To detect E. coli (uidA) in the samples, a 3-4 Log CFU/mL cell concentration was required. However, E. coli was detected at 1 Log CFU/g in fresh pork, beef, and fresh-cut lettuce after 5, 5, and 3-h enrichment, respectively. In conclusion, 5-h enrichment for fresh meats and 3-h enrichment for fresh-cut lettuce in EC broth at $44.5^{\circ}C$, and PCR analysis using uidA gene-specific primers were appropriate to detect E. coli rapidly in food samples.
