  • Physicochemical and sensory characteristics of the green tea dasik varying the added value of oligosaccharide were investigated and the products were surveyed by elementary school students regarding the acceptability. Protein and ash contents were significantly higher and fat contents were significanlty lower in the samples with oligosaccharides compared to those in commercial ones(p<0.05). Commercial samples had significantly higher values in all of the textural characteristics using textural analyzer compared to those of the developed dasik sample groups. In analytical sensory evaluation, varying the amount of oligosaccharide, commercial samples had significantly higher values of sweetness, hardness, and cohesiveness and lower values of savory aroma and falvor compared to those of developed dasik(p<0.05). Savory aroma and flavor were highly negatively correlated with textural hardness, springiness, chewiness, gumminess, and cohesiveness(p<0.01), while sensory sweetness and hardness were significantly positively correlated with textural springiness(p<0.05), chewiness, gumminess, and cohesiveness(p<0.01). When surveying elementary school students regarding the acceptability of green tea dasik and commercial samples, green tea dasik 2 was the most preferred with significance in color. Regarding aroma, green tea dasik 1 received the highest acceptability (p<0.05). In the flavor, both dasik 1 and 2 received higher score than those of the commercial dasik. In overall acceptability, both green tea dasik 1 and 2 were preferred to the commercially sold ones with significance(p<0.05).

  • In order to examine the changes of commercial value during storage conditions and shelf-life of Chungkookjang, response surface methodology of SAS program was applied to monitor orgenoleptic properties and color changes to determine optimum storage conditions. Lightness (L) value of vacuum-packed Chungkookjang showed under the 1% significance probability with high influence in all conditions such as sterilized temperature, storage time and storage temperature. Redness (a) value of vacuum-packed Chungkookjang was increased during highly sterilized and storage temperatures, and was individually influenced. One of the generally packed sample also showed that significance value was influenced under 10%, during high storage temperature. Yellowness (b) value of vacuum-packed Chungkookjang showed the significance probability under 1% during storage time and temperature, and under 5% during sterilized temperature. Also, stational point showed saddle type in both packaging samples. In case of vacuum-packed Chungkookjang, compatibility of odor was influenced by sterilized temperature under 10% significance probability. But generally packed samples have an effect on storage time under 1% significance probability effect on storage time, and sterilized temperature under 5%. In case of vacuum-packed Chungkookjang, compatibility of taste was highly concerned with storage time under 1% significance probability, whereas generally packed samples were concerned with storage temperature under 5% significance probability. Overall palatability of vacuum-packed samples showed maximum value of 5.15 on sterilized temperature ($61.92^{\circ}C$), storage temperature ($6.79^{\circ}C$) and storage time (56.48 days) during storage.

  • The Korea has significant tidal current energy resources, but it is so hard to work underwater for tidal turbine installation. Therefore commercial diving work is very important for tidal current generator. Also, Jangjuk channel is vary famous as proper area to generate tidal current energy. Nevertheless, no one is studied about characteristics of commercial diving works with installation of tidal current generator. The purpose of this study is to introduce commercial diving with work types and investigate critical limits of diving working under the conditions, which are working only to minutes at slack tide during the neap tide. As the results, work types are five as like mooring installation, OMAS(Offshore Maintenance Access System), support structure installation, cable and turbine installation. Here, the original construction period is expected about 4 months, but the construction take 18 months to complete. The cause of extends construction period is insufficiency of researching tidal current conditions at the site and ignorance of slack tide which need to secure diving working time. Total diving working times are 110th during 18 months, the highest percentage of diving times is turbine installation about 43.6 %, and cable, mooring installation and support structure construction are 27.3 %, 15.5 %, 13.6 %, respectively. On the basis of this study, estimation of times of commercial diving is possible with work types of tidal current power, and has a significance as basic data to determining construction period.

  • The Caravanserai, which can be discovered in the Islamic States in the regions of the Northern Africa and the Middle Asia, still maintains its profound influence to the Islamic World as one of significant edifices in the Islamic World. The majority of the Islamic people at the time of the foundation of Islamic State around AD. 7th century was the nomads, and a trade by means of caravan with their neighboring people was their critical activity for obtaining the necessities of life. With its political and social condition of the Islamic State stabilized and economy developed, the scope of commerce began to grow and the scale of trading with foreign countries started to expand. Along with this economic expansion, the caravanserai began to take a shape as a channel through which not only could the commercial commodities be traded but also religious Islamic ideas and important information could be spread into and shared with the people of neighboring countries. The significance of the caravanserai comes from such observation that it did play major roles in consolidating the solidarity of Islamic states and keeping a religious unity among them. The caravanserai, heading far beyond being a mere commercial center, ultimately functioned as a seedbed of life and spirit of the Islam. Starting from the understanding of social and political significance of the caravanserai, I set the first objective of this article to read into the architecture and interior design of the caravanserai and understand the general characteristics of the Islamic architecture and interior design.

  • In China, with the rise of third-party payments such as WeChat Pay and Alipay, the traditional business of banks has been greatly affected. Banks can encourage and expand QR code payments to merchants. Therefore, it is meaningful to analyze and study the QR code work of banks. The purpose of this study is to analyze the effect of the execution of the zero-rate of the comprehensive payment QR code combined with the payment cycle and Funds Transfer Pricing (FTP) on commercial banks in China. Based on the manually collected customer data of Chinese commercial banks, this paper conducts a case analysis combined with the calculation method of financial indicators. As a result of the study, it was found that commercial banks need to continue to implement the policy as the advantages of introducing the integrated QR code fee rate 0 policy are greater than the disadvantages. This paper provides feasible suggestions on how to quickly occupy the offline payment market for commercial banks, which has guiding significance for commercial banks' marketing decisions. Presently, there are few studies on the zero-rate subsidy policy implemented by Chinese commercial banks.
