한국산 2조 및 6조 겉보리 10품종들의 품종적 변이가 ${\beta}-glucan$의 함량과 맥아제조시 맥아의 품질 특성에 미치는 영향을 조사하였다. 2조 보리는 용적중, 천립중 및 풍만도에 있어서 6조 보리에 비해 월등히 높았으며 이는 맥아 추출물의 함량을 높이는 인자가 되었다. ${\beta}-Glucan$의 함량은 6조 보리가 2조 보리에 비해 높았다. 보리 품종들은 맥아의 품질 특성 및 맥아의 변형정도(degree of malt modification)에 있어서 차이를 보였으며 특히 6조 보리는 제맥과정중 ${\beta}-glucan$의 함량 감소가 2조 보리에 비해 낮았다. 보리의 최초 ${\beta}-glucan$ 함량은 맥즙의 점도에 영향을 미칠 수 있고 제맥후의 맥아 ${\beta}-glucan$ 함량이 맥즙의 점도와 직접적인 상관관계를 보여주었다. 전반적으로 2조 보리가 6조 보리보다 맥아 품질이 우수한 것으로 나타나 6조 보리의 맥주용으로서의 이용이 어려울 것으로 생각되나 제맥조건을 조절함으로써 일부 6조 보리의 맥아제조 적성을 재 검토할 필요가 있다고 사료되었다.

This study was performed to observe the quality characteristics of Eunhakong dasik and Small Black Soybean dasik prepared with different addition rates of chlorella powder. For the Hunter's color values, the $L^*,\;a^*,\;and\;b^*$ values of both dasiks decreased with the addition of chlorella powder. The cohesiveness and gumminess of both dasiks were not dependant on the chlorella powder additions. However, the hardness of the Eunhakong dasik with 8% chlorella powder increased. The springiness and brittleness of the Eunhakong dasik had a tendency to decrease as the addition rate of the chlorella powder increased. In terms of sensory quality, both the dasiks were improved by the addition of 4% chlorella powder. Therefore, in subsequent examinations, the chemical characteristics of both dasiks were determined for the 4% addition of chlorella powder. The moisture and crude lipid contents of both dasiks were not influenced by the addition of chlorella powder. Carbohydrate content was highest in the Eunhakong dasik with 0% chlorella powder, and in the Small Black Soybean dasik with 4% chlorella powder. Conversely, crude protein content was highest in the Eunhakong dasik with 4% chlorella powder, and in the Small Black Soybean dasik with 0% chlorella powder. The crude lipid content of the Small Black Soybean dasik with 4% chlorella powder was lower than that of the control without chlorella powder. For mineral content, the K content of both dasiks was not influenced by the addition of chlorella powder. The Ca, Mg, and P contents of both dasiks with 4% chlorella powder, respectively, were lower than those of the dasik with 0% chlorella powder. Finally, the total amino acid content of the Eunhakong dasik tended to decrease, while that of the Small Black Soybean dasik incrased, with the 4% addition of chlorella powder.

Content centric networking (CCN) is regarded as promising internet architecture because it can provide network efficiency in terms of bandwidth consumption by separating contents from a specific network location and decrease network congestion events. However, the application of a CCN does not widely consider the side effects of mobile devices, particularly mobile content sources. For content source mobility, a full routing update is required. Therefore, in this study, a route optimization scheme is proposed for mobile content sources in a CCN environment to provide low communication overhead, short download time, and low resource consumption. The proposed scheme establishes a direct path between content requesters and a mobile content source for the exchange of interest and data packets using interest-piggybacked data packets. Based on the inherent CCN naming characteristics, the content source does not know the name prefix of the content consumer, and thus the proposed optimized CCN scheme utilizes the content router in the home domain of the content source.

Objectives : This study aimed to investigate value differences among Gastrodiae Rhizoma samples(GM, GC, G1, G2 and G3) in various characteristics as well as to provide basic guideline for various processes such as steaming and drying of Gastrodiae Rhizoma. Methods : Gastrodiae Rhizoma were steamed and dried at different temperature and times. They were divided into samples (GM; cultivated, steamed and dried in Muju, GC; cultivated and dried in China, G1; steamed and dried at $55^{\circ}C$ for 60 hours, G2; steamed and dried at $55^{\circ}C$ for 120 hours, G3; steamed and dried at $70^{\circ}C$ for 120 hours) for experiment. They were extracted using water, freeze dried and powdered to analyze gastrodin content, antioxidant activity and sensory evaluation. Results : Proximate composition and the amount of free sugars of Gastrodiae Rhizoma had a little bit differences. Phenolic and flavonoid content of samples were increased by increasing drying temperature and times. Gastrodin content had different values by drying method and G3 was the highest in comparison with others. Increasing drying times led to a increasing in radical and nitrate scavenging activity in samples. Regarding to sensory evaluation, G3 was selected as the best sample according to its highest hedonic score mean (6.11/7) among all samples for appearance, color, flavor, overall acceptability. Conclusions : The results indicated that G3 sample was effective in views of antioxidant activity, gastrodin content and sensory characteristics. Moreover, Gastrodiae Rhizoma cultivated in Korea were investigated with higher antioxidant activity, gastrodin content and sensory characteristics than those cultivated in China.

The goal of this research was to an optimum conditions for the brown rice conditioning from data of milling characteristics after conditioning of the brown rice. The range of the initial moisture content of the sample was 13%, 14%, and 15%, the range of the increment of the moisture content was 0.4% and 0.8% with respect to the initial moisture content, and a ripe time after conditioning was eight hours. The results obtained from this research can be summarized as fellows. 1 The crack ratio after conditioning the brown rice with the initial moisture content was increased as the initial moisture content decreased and increment of the moisture content increased. The crack ratio of the milled rice was increased than that of the non-conditioned brown rice and decreased with the conditioned brown rice with the increment of the moisture content of 0.4% and 0.5%. 2. The broken rice ratio after conditioning the brown rice with the initial moisture content was a little higher than that of the non-conditioned brawn rice. The broken ratio of the conditioned brown rice with the increment of the moisture content of 0.4% was increased around 0.2∼0.4% with respect to the non-conditioned brown riced and the broken ratio of the brown rice was high with increased amount of water sprayed during conditioning process. 3. The moisture content of the milled rice after conditioning the brown rice with the initial moisture content increased around 0.3∼0.8% with respect to the non-conditioned milled rice. 4. The electric energy consumption on milling process with the conditioned brown rice by the initial moisture content was decreased 3.4∼39.1% with respect to the non-conditioned brown rice.

Meat comes from the skeletal muscles of farm animals, such as pigs, chickens, and cows. Skeletal muscles are composed of many muscle fibers. Muscle fibers are categorized into three types, fiber type I, IIA, and IIB, based on their contractile speed and metabolic properties. Different muscle fiber types have different biochemical, physiological, and biophysical characteristics. Especially, the characteristics of muscle fiber type I and IIB are opposite to each other. Muscle fiber type I has a relatively strong oxidative metabolic trait and a higher content of lipids. In contrast to fiber type I, muscle fiber type IIB has a strong glycolytic metabolic trait and a relatively lower content of lipids and a higher content of glycogen. Muscle fiber type IIA has intermediate properties between fiber type I and IIB. Thus, muscles with different fiber type compositions exhibit different ante- and post-mortem muscle characteristics. In particular, the different metabolic traits of muscles due to the different compositions of the fiber types strongly affect the biochemical and physiological processes during the conversion of muscle to meat and subsequently influence the quality of the meat. Therefore, understating muscle metabolism and muscle fiber characteristics is very important when discussing the traits of meat quality. This review is an overview on basic muscle metabolism, muscle fiber characteristics, and their influence on meat quality and finally provides a comprehensive understanding about the fundamental traits of muscles and meat quality.

In November 2018, virtual pop band K/DA, with the use of holograms and actual K-pop girl group members, performed its debut album titled "POP/STARS" at the opening ceremony of the League of Legends S8 final, hosted by Riot Games. The fan culture that exists for real singers adapts itself to virtual bands, and K/DA, consisting of virtual characters, encouraging the production of user created content (UCC). However, this form of UCC is different from the most common one, meaning that this type of band generates another way of consuming content. Therefore, this study examines how K/DA's digital characters are transformed and reproduced by UCC and how the original producers' content differs from them. Firstly, the development of this study considers the open characteristics of UCC, such as user type, created motivation, created process, content type and sharing method. In the second part, the virtual idol Hatsune Miku and virtual band Pentakill will be analysed to understand UCC. Thirdly, K/DA will be analyzed as a case study based on three factors: created motivation, content type and sharing method. In this manner, this study aims to explain how UCC for virtual bands reproduce and consume original content and expand their commercial value.
