  • Using a qualitative method, this paper described briefly the well-being-oriented consumers consciousness toward sustainability concept. The paper identified the major obstacles facing well-being society as evidenced by consumers own experiences for consuming products which are meet the necessity for environmental preservation. Over seventy percent of respondents who had a experience consuming the sustainable products said that they consumed it for themselves and their family's health of all things. Beside their interests about health, they made mention of the safety of sustainable products, high quality of sustainable products, to preserve our environment, confidence in sustainable products, encouragement from others, and curiosity for sustainable products. The respondents who did not consume the sustainable products argued that high price of sustainable products, genuineness of sustainable products, lack of information about sustainable products, unconcern about sustainable products, and difficulty to access to sustainable products were not allowed them from consuming the sustainable products.

  • The quality of guava (Psidium guajava L.) leaves processed using different methods, such as fermentation, steaming, and roasting were investigated. The total phenolics content was highest in the roasted guava leaves. While tyrosinase inhibition and electron donating abilities were highest in steamed guava leaves. The overall palatability showed higher scores in both fermented and steamed guava leaves compared to roasted ones. Upon blanching and steaming of guava leaves, the total phenolics content, tyrosinase inhibition ability, and electron donating ability decreased as the treatment time increased. The overall quality properties were significantly higher in steamed than the blanched samples. The sensory scores, however, were low mainly due to the astringent taste of guava leaves. Thus, it was found that the removal or masking of the astringent taste of guava leaves is of primary concern for their further use.

  • We sought to optimize parboiled rice preparations with respect to nutritional composition and to compare the physicochemical properties of polished, glutinous rices and Olbyossal (parboiled rice). Crude lipid contents (all w/w) were: brown glutinous rice (1.92%) > Olbyossal (1.13%) > glutinous rice (1.08%) > polished rice (0.32%). The crude ash content of Olbyossal was greater than that of polished rice. There was no significant difference in crude protein level between Olbyossal and polished rice. Total dietary fiber content (all figures are w/w) was higher in Olbyossal (3.79%) than in polished rice (1.67%). With respect to mineral content, P (249.16 mg%), K (144.67 mg%), Na (35.41 mg%), and Mg (30.24 mg%) levels were higher in Olbyossal than in polished rice. There was no significant difference in fatty acid or amino acid content between polished rice and Olbyossal. The L value (lightness) of Olbyossal was lower than that of polished rice but the hardness of Olbyossal was greater.

  • To improve the levels of ${\gamma}$-aminobutyric acid (GABA) in germinated brown rice, chitosan and glutamic acid were treated during the brown rice germination. The GABA contents in germinated brown rices were 425.7 nmole/g and 637.0 nmole/g at germination temperature of $25^{\circ}C$ and germination time of 72 hrs. Response surface methodology(RSM) was used to monitor characteristics of germination from brown rices. As glutamic acid and chitosan concentration were increased, the GABA content was also increased. The ranges of optimum conditions were $105{\sim}160\;ppm$ in chitosan concentration and $200{\sim}290\;ppm$ in glutamic acid concentration. Predicted values at the optimized conditions were acceptable in comparison with experimental values.

  • The aim of the present contribution is to consider and underline the essential interactions among the historical knowledge, the seismic vulnerability assessment, the investigation experimental tools, the preservation of the architectural quality and the strengthening design in regard to architectural heritage conservation. These topics are argued in relation to Palazzo Murena in Perugia, designed in the eighteenth century by the famous Architect Luigi Vanvitelli, and currently headquarters of the city's University. Based on the surveys and the visual inspections, a preliminary a priori global analysis has been performed by means of the FME method. The obtained results permitted to plan an experimental tests campaign inclusive of structural health monitoring. The new achieved "knowledge" of the building allowed to refine the seismic safety assessment. In particular it was highlighted that the "mezzanine floor" can be a vulnerable element of the building with the collapse of its masonry walls. Preserving the architectural characteristics, a local reinforcement intervention is proposed for the above-mentioned level; this consists of the application of plaster with FRCM, assuring an adequate strength, without burden the masonry structure with additional weight, and therefore a decreasing of the seismic vulnerability. The necessity to consider, in this ongoing research, other local mechanisms is highlighted in the unfolding of the last part of work.

  • In order to develop of health-oriented convenience foods for rice consumption, functional Misutkaru drink was made by adding several medicinal herbs extracts to fundamental Misutkaru based cereal powder(rice, barley and soybean). Fundamental Misutkaru drink was prepared with the ratio of cereal mixed rice(5g), barley(5g) and soybean(5g) on water (100 mL) and several medicinal herbs extracts. Liriopis Tuber(50%), Omija(15%), Ginseng(10%) and Jujube(25%) were mixed to fundamental Misutkaru as functional Misutkaru. And then it was extracted to added water of 10times during 36hrs at 75$^{\circ}C$. For instant Misutkaru drink of health-oriented convenience foods, mixture of them was made with fundamental Misutkaru drink(80%), extract of several medicinal herbs(20%), and it's sensory score was high. Autoclaved functional Misutkaru drink for long storage period was changed rheological type badly. Overall acceptability and storage period of nonautoclaved functional Misutkaru drink to added extract of several medicinal herbs was higher than fundamental Misutkaru drink.

  • Although most lemons are imported into Korea, their consumption is increasing. Development of domestic varieties of Jeramon and Minimon is currently underway in an effort to meet the increasing demand for fresh lemons. In this study, an analysis of the physicochemical characteristics of Jeramon and Minimon, including their flavor components and antioxidant properties, was conducted. The results revealed that these new varieties of Korean lemon can be regarded as good sources of antioxidants and phytochemicals. Compared to Sunkist, the most consumed lemon variety in Korea, Minimon contained more than twice as much β-cryptoxanthin, and the content of L-ascorbic acid was more than three-four-fold higher in both Minimon and Jeramon. In addition, results from measurement of DPPH and ABTS radical scavenging activities indicated that Jeramon extract exhibited the highest antioxidant activity. In the volatile profile analysis, the profiles of volatile components showed high similarity among the three lemon samples, and the composition ratio was largely dominated by terpenoids. A markedly higher ratio of d-limonene and thymol was detected in the Minimon variety compared with that in the other two varieties. Collectively, the findings from this study on Korean lemon varieties provide a basis as well as valuable guidance for breeding domestic lemon varieties.

  • Terrestrial Laser Scanning(TLS) was developed at the mid-to-late 1990s. This technique enables to perform reconnaissance surveying of regions or structures hard to access. Besides, TLS has been extended its application gradually such as preservation of historical remains, underground surveys, slopes, glaciers monitoring and so on. However, though the technique has a lot of advantages, an application for structural health and safety monitoring is a beginning stage and it need much research. Therefore in this study, as a groundwork, the estimation model on stress of structures using TLS and Finite Element Method(FEM) applied by the Digital Elevation Model(DEM) technique of geoinformatics is proposed. For the verification of this model, experiments were performed with a continuous steel beam subjected to point loads and outputs were compared with those of electrical strain sensors.
