With the recent rise in nuclear families and single-member families, there is a need for the kind of home management unaffected by neither space nor time. Moreover, electronic devices in and around the home need to be managed efficiently and prevented from overheating, and there is an increasing risk of fire, theft, and leak of personal data with these devices, which is leading to an increase in the economic costs. Accordingly, there is a growing need for an efficient and secure smart home management system. This paper proposes a home management system that uses smart devices. This system has addressed the shortcomings of a conventional Internet-based home network. Furthermore, it communicates with IoT-enabled devices and features intelligent information home appliances that are isolated from personally identifiable information and which are secure against advanced persistent threats, a type of cyber-attack.

This studies were carried out to investigate the physiological characteristics of lactic acid bacteria related to kimchi fermentation. 157 strains of lactic acid bacteria were isolated from home-made kimchi of Taegu district. 144 strains of isolated lactic bacteria showed resistance to artifical gastric juice and bile. Among isolated strains, fifteen strains were selected according to the growth characteristics. The selected strains survived for 24 hours in artifical bile after incubation for 3 hours in artificial gastric jucie (pH 2.5). Especially, three strains such as B-10, K-2, and F-3, showed little viable cell change for 3 hrs incubation in artifical gastric juice. The selected strains showed low viability in artificial gastric juice but high in artifical bile. The selected strains also showed significantly antimicrobial activities to pathogens such as Listeria monocytogenes, Escherichia coli, Bacillus subtili, Staphylococcus aureus and Vibrio parahaemolyticus. The fifteen selected strains were identified as Lactobacillus plantarum, Lactobacillus sake and Leuconostoc mesenteroides.

Viscosity development pattern, in aqueous sodium hydroxide, of rice starches isolated from various hydration groups of milled rice was investigated. The maximum viscosity and viscosity development rate of Japonica rice starches at a given alkali concentration were loswer than those of J/Indica counterparts. The difference in the viscosity development rate of starches by increment of 0.1N (0.02 meq/g) was greater in J/Indica rice starches in comparison with Japonica ones. Viscosity of rice starch was not correlated to that of rice flour and to hydration rate of milled rice.

Unknown bacterium isolated from garlic was characterized using phenotypic methods, phylogenetic analysis, DNA-DNA hybridization, and cultural methods. The strain was identified as typical leuconostoc; Gram-positive, non-sporeforming, heterofermentative, catalase-negative and spherical. Although its 16S rRNA gene sequence showed high homology to Leuconostoc argentinum DSM $8581^T$(99.8%), DNA-DNA hybridization experiments indicated it represents novel genomic species in the genus Leuconostoc. The garlic-specific leuconostoc was more resistant to antimicrobial activity of garlic compared to other common laboratory lactic acid bacteria, and was even stimulated by low concentrations (1-2%) of garlic extract supplemented in trypticase soy broth. Growth stimulation was concentration-dependent when tested with residual aqueous layer after solvent extraction of fresh whole garlic extract.

Structural studies of membrane proteins, importantly involving interpretation of genomics information, many signaling pathway and major drug target for drug discovery, are having difficulty in characterizing the function using conventional solution nmr spectroscopy and x-ray crystallography because phospholipid bilayers hindered fast tumbling and crystallization. Here, we studied the structure of the pf1 coat protein in oriented phospholipid bilayers by home-built solid-state NMR probe. Bacteriophage pf1 was purified from Paeudomonas Aeruginosa and coat protein of bacteriophage pf1 was isolated from DNA and other proteins.

The purpose of this study is to examine the effect of two kinds of Master and Chief Engineer's communication style on group conflicts and members' attitude including job satisfaction and organizational commitment, and to analyze the moderating effect of the isolation from home and community on the relation between the both of communication styles and the several behavioral variables in ship organization. This empirical result demonstrates the fact that Master and Chief Engineer's direct communication with crew has lower conflict and higher job satisfaction and organizational commitment than their indirect one through Chief Officer and First Engineer. In addition, it illustrates the isolation from home only effects moderately on the relation between the communication style and group conflict, and also the direct communication style reduces more the conflict in the group to show less isolation from home. To conclude, this study reveals that job satisfaction and organization commitment could be heightened by proper communication style of Master and Chief Engineer and it would utilize the job performance of ship organization in the long-term.

In order to evaluate the safety of greenhouse horticultures, a large number sample sources were collected, and the fungi of Aspergillus sp. and Penicillium sp. were isolated from them. Indirect competitive ELISA method and high performance liquid chromatography (HPLC) were applied to confirm the ochratoxin A producing abilities of isolated strains. One hundred ninety two sample sources including soil, pepper, strawberry and water mellon were collected for fungi isolation from western Gyeongnam, Andong and Gyeongbok. One hundred forty two strains of Aspergillus sp. and one hundred fifty three strains of Penicillium sp. were isolated respectively from them. The isolated fungi were tested for the production of ochratoxin A by ELISA. After culture of them on the modified sucrose low salt medium at $28^{\circ}C$ for 15 days, we found that five strains of Penicillium sp. produced ochratoxin A at the levels of $0.084{\sim}2.128\;{\mu}g/mL$. Among them, #129-2 strain isolated from water melon, showed the highest level of ochratoxin A as $2.128\;{\mu}g/mL$ broth. However, all of isolated Aspergillus sp. didn't produce ochratoxin A. When we compared the results of ELISA method with HPLC method, ochratoxin A production of each isolated strains showed very similar levels.
