  • The Salvia plebeia R. which is the biennial plant belonging to the labiatae department, grows widely in Korea. This study was performed to evaluate the antioxidant activities and anti-allergic effects of Salvia plebeia R. leaves (SPLE) or roots (SPRE). Using ethanol extracts, both leaves and roots induced significant radical scavenging activity against DPPH and ABTS radicals in a dose dependent manner (p<0.05). Superoxide dismutase (SOD)-like activity of SPLE was significantly higher than that of SPRE at all concentrations. Treatment of the RBL-2H3 cells with SPLE and SPRE in vitro decreased ${\beta}$-Hexosaminidase release and significantly inhibited IgE-antigen complex-mediated IL-4 and TNF-${\alpha}$ mRNA expression in RBL-2H3 cells. These findings suggest that Salvia plebeia R. can protect or reduce allergic asthma through high antioxidant and anti-allergic reactions.

  • Aroma compounds in sun-dried salt according to saltern material and packaging box were extracted by the headspace and were isolated by using GC-MS. These compounds were identified including ketones, heterocyclic compounds and six other compounds. Major aroma compounds in salts were identified as 4-methyl-2-pentanone, 5-methyl-3-hexanone, 4-methyl-3-penten-2-one, 2-hexanol, benzothiazole, 2,4-bis(1,1-dimethylethyl)-phenol, and 1,3,5-tri-tert-butyl benzene. However, we found no significant differences according to the saltern materials in three salts. Salts stored in Chamaceyparis obtusa (Sieb. et Zucc.) had more diverse aroma profiling than those in Pinus densiflora and Paulownia coreana. We consider that it need to research the development of high value added products for new aromatic salt.

  • The defense system development process is a process of developing various systems that perform functions in various functional areas such as battlefield awareness, command control, force application, and logistical support. In other words, the defense system development process is a process of developing many systems simultaneously in various functional areas. Various systems developed through this process should be interoperable so that they can be integrated and operated in a joint warfighting environment. To successfully implement this, the US Department of Defense uses the Joint Capability Integrated Development System(JCIDS) for the defense system development, and within this JCIDS processes the Capability Based Assessment(CBA) methodology as its core technology. This CBA methodology transforms the mission activity requirements to functional capability requirements logically and transforms the functional capability requirements to system requirements logically also. Smart City is a city that improves the convenience and quality of life of the citizen by integrates various systems that perform various functions of the city and smarties various functional systems with smart services by using IT technology. In other words, defense system development and smart city development have a common feature of the process of developing many systems simultaneously in various functional areas. In order to address the problem of having to develop many systems simultaneously in each functional area, it is important to logically transform the various mission scenarios into functions and logically transform the functions into systems. Therefore, a joint capability integrated development system and its core methodology, Capability Based Assessment(CBA), can be applied to smart city development. This paper proposes a method for performing a smart city concept design method using the capability based evaluation (CBA) method.

  • Recently demand for safer and healthier food has augmented with advancements in health conditions. Food ingredients with yet to be known safety and functionality, are being investigated for their safety or detrimental effects. The Ministry of Food and Drug Safety has introduced "health functional food" by the "Health Functional Food Act" to evaluate bio-functional and safety properties of raw materials using standard methods including in-vitro and in-vivo testing before human consumption. Despite recent growth in net worth of domestic functional food market, most of the raw materials are not from local Korean industries with own research and development, and mostly terrestrial not marine resources. Geographically, Korea has access to diverse marine bio-resources that need to be managed and utilized sustainably. Recently, diverse novel physiologically active substances have been reported from marine organisms. Hence, the development of functional foods from marine bio-resources is considered as an inevitably important task.

  • In the present report, the effects of blanching, steaming, and high temperature/high pressure processing (HTHP) on the amino acid contents of commonly consumed Korean root vegetables, leaf vegetables, and pulses were evaluated using an Automatic Amino Acid Analyzer. The total amino acid content of the samples tested was between 3.38 g/100 g dry weight (DW) and 21.32 g/100 g DW in raw vegetables and between 29.36 g/100 g DW and 30.55 g/100 g DW in raw pulses. With HTHP, we observed significant decreases in the lysine and arginine contents of vegetables and the lysine, arginine, and cysteine contents of pulses. Moreover, the amino acid contents of blanched vegetables and steamed pulses were more similar than the amino acid contents of the HTHP vegetables and HTHP pulses. Interestingly, lysine, arginine, and cysteine were more sensitive to HTHP than the other amino acids. Partial Least Squares-Discriminate Analyses were also performed to discriminate the clusters and patterns of amino acids.

  • The objectives of this present study were to compare the contents and determine optimum extraction conditions for the rosmarinic acid (RA) and caffeic acid (CA) from leaves of Korean Perilla frutescens varieties. RA and CA from leaves of cv. Bora, a breeding line of P. frutescens were isolated and elucidated using various spectroscopic data. On the basis of 2 phenolic acids, optimum extraction conditions were obtained by employing 50% EtOH for 60 min at $25^{\circ}C$. We reported for the first time on the contents of RA and CA from leaves of 32 Korean varieties. Among them, leaves of P. frutescens Brit. var. acuta Kudo I exhibited the highest RA content ($8.53{\pm}0.57$ mg/g) and CA content ($2.33{\pm}0.11$ mg/g) showed the highest in the P. frutescens Brit. var. viridis Makino. Interestingly, average RA content ($2.66{\pm}0.17$ mg/g) showed a markedly higher than that of CA ($1.98{\pm}0.16$ mg/g) in Korean varieties. These results suggest that concentrations of the RA and CA in P. frutescens leaves could be a key factor in the selection process of a high quality species.

  • This study was conducted to verify the potential of Allium hookeri to control blood glucose metabolism in diabetes model. We fed the experimental diets(ALE, ARE) supplemented with the extract of Allium hookeri leaf or root at 1% of diet to the diabetic mice (C57BLKS/J, db/db) for 8 weeks. Hetero and control mice were fed the control diet without any extract of Allium hookeri leaf or root. At 8th week of feeding the diets, we measured body weight, blood glucose, HbA1c, and plasma insulin levels and conducted an oral glucose tolerance test (OGTT) and staining insulin immunoreactive cells in islets of pancreas. ARE group treated with the root of A. hookeri showed significantly lower blood glucose levels than the Cont group at 120 min in the OGTT. However, HbA1c level was significantly reduced in both ALE and ARE groups, and higher serum insulin levels and increased density of insulin immunoreactive cells compared with the Cont group were found in these 2 groups. Based on these results, A. hookeri is considered to be effective in improving glucose tolerance by partially affecting insulin secretion and it may be used to prevent and treat diabetic disease.

  • The development of functional foods started booming from several years ago in the world. The size of functional materials are in the range of micrometer level. This size can be much smaller into nanometer level to be more effective. We face some problems from the materials, such as flavor, taste, color, viscosity, etc. in functional materials. The problems can be solved by micro / nanoencapsulation technique. This paper showed some results of the research related on the technique for functional milks and dairy products. The nono / microcapsules are the form of liquid instead of solid. Coating materials used were fatty acid esters, and core materials were lactase, iron, ascorbic acid. isoflavone, and chitooligosaccharide. The ranges of capsules are from 100 nm to 200 ${\mu}$m. The sample milks added nano/microcapsules were homogeneous and prevented the defects of core materials. It was observed that nano / microcapsules in milk and dairy products were effective as functional material without defaults. It was indicated that targeted functional foods can be developed further in various foods by nanotechnology.

  • A non-functional requirement is a property or quality that the proposed systems have to support the functional requirements. A non-functional requirement is reflected by quality attribute These non-functional requirements playa crucial role during system development, serving as selection criteria for choosing among decisions. It should be continuously considered through the software development process. In spite of the importance of the non-functional requirements, it received little attention because of ambiguousness and invisibility of non-functional requirements. Therefore non-functional model which is a process to analyze the non-functional requirement is proposed for improving the management efficiency of non-functional requirements. Also, this paper presents the trace among the UML diagrams to the conceptual model. According to the non-functional requirement development process, this paper achieved performance-based case study. After then, non-functional requirement should be traced using the UML diagrams.
