One of the major trends of automotive networking architecture is the introduction of automotive Ethernet. Ethernet is already used in single automotive applications (e.g. to connect high-data-rate sources as video cameras), it is expected that the ongoing standardization at IEEE (IEEE802.3bw - 100BASE-T1, respectively IEEE P802.3bp - 1000BASE-T1) will lead to a much broader adoption in future. Those applications will not be limited to simple point-to-point connections, but may affect Electric/Electronic(EE) Architectures as a whole. It is agreed that IP based traffic via Ethernet could be secured by application of well-established IP security protocols (e.g., IPSec, TLS) combined with additional components like, e.g., automotive firewall or IDS. In the case of safety and real-time related applications on resource constraint devices, the IP based communication is not the favorite option to be used with complicated and performance demanding TLS or IPSec. Those applications will be foreseeable incorporate Layer-2 based communication protocols as, e.g., currently standardized at IEEE[13]. The present paper reflects the state-of-the-art communication concepts with respect to security and identifies architectural challenges and potential solutions for future Ethernet Switch-based EE-Architectures. It also gives an overview and provide insights into the ongoing security relevant standardization activities concerning automotive Ethernet. Furthermore, the properties of non-automotive Ethernet security mechanisms as, e.g., IEEE 802.1AE aka. MACsec or 802.1X Port-based Network Access Control, will be evaluated and the applicability for automotive applications will be assessed.

Korean traditional culture has a long history and it is rooted in the deep down our national culture. It is like bread and pride for Korean people. The tale of Cheyong is a precious cultural heritage, which has existed in the public awareness of the Korean people since the period of unified Silla. Based on its mysterious and beautiful story, the value of traditional culture can be revealed through development of digital contents. With such precious cultural resource we can digitalize the fun contents which the general public can enjoy. Ways of digitalize of cultural archetype has been suggested by analyzing the content elements of the tale of Cheyong. Also, by making scientific approach to the development process of digitalization, the possibility of digitalization has been found through 3D animation restoration process for Cheyong Dance and the process of making the tale of Cheyong into animation. Through analyzing the contents development process of cultural archetype of the tale of Chetyong, a cultural archetype sourcehas been developed which has a great value as a contents product that can be developed and used as various cultural content art works. With studies on the theory of development method for digitalization of traditional culture, scientific studies and investigation have to be continuously carried out so the digitalization of Korean cultural heritage, which will shine in the world, can be continued as well.

The purpose of this study was to investigate teachers' responses to curriculum evaluation of gifted curriculum in visual arts. Especially, this study examined whether there are differences of the responses among three types of institutions for gifted education (institution for gifted education, community based gifted classroom, and school based gifted classroom). Teachers from these three types of institutions for gifted education were interviewed. The results are as follows. First, teachers viewed that consideration is needed for 3 criteria. Teachers from different institutions showed different responses to 'professionalism of working personnel' and 'utilization of advisory committee'. Second, teachers viewed that 13 criteria need consideration. Teachers from different institutions showed different responses to 'support personnel for gifted education' and 'educational equipment and resource supply'. Third, teachers viewed that consideration is needed for 2 criteria. Teachers from different institutions showed different responses to 'efforts for professional development of instructors'. Fourth, teachers viewed 4 criteria need consideration. Teachers from different institutions showed different responses to 'budget planning for next year'. Based on the findings, implications for developing and implementing the evaluation criteria for the gifted curriculum in visual arts were discussed.

This study evaluated the antioxidant and anti-inflammatory activity of ethanol extracts using three parts of the chives plant: the bulb, the leaf, and the flower. As a result of DPPH and ABTS radical scavenging ability, the scavenging activity of the flower extract was higher than that of the bulb and leaf. In addition, as a result of FRAP analysis, antioxidant activity increased in all extracts depending on the extract concentration. The total polyphenol content was high in the following order: flower (11.29±0.37 mgGAE/g) > leaf (6.61±0.14 mgGAE/g) > bulb (5.7±0.67 mgGAE/g) extract. The cytotoxicity of the three extracts against rat macrophage RAW264.7 cells and HaCaT cells, both of which are human cutaneous keratinocyte cell lines, was minimal. NO by LPS was generated as a result of examining the anti-inflammatory activity of each extract through the NO colorimetric analysis method and ELISA. TNF-α secretion was decreased to a significant level in the flower ethanol extract. Therefore, these results indicate that there is a high possibility that the ethanol extract of chives, a natural plant resource, can be used as a cosmetic raw material.

This study was conducted to investigate the changes of major components and bioactivities of tea produce. The tea produce were made by various methods, with different degree of fermentation during manufacturing process. Except green tea, degrees of fermentation in Wizo Tea, Ilsoae Tea, and Hwang Tea were $5{\sim}10%,\;50{\sim}60%$ and $70{\sim}80%$ respectively. The result are as follows : The general component(moisture, crude ash, crude lipid, and crude protein) and the content of total polyphenol in tea products were not shown significant difference during the fermentation process. The content of caffeine in tea extracts decreased sharply as degree of fermentation of tea. In comparison of hunter values in tea extract, lightness was decreased as fermentation redness (a) was all (-), and yellowness(b) was increased sharpy with degree of fermentation. Radical scavenging activity using DPPH of tow kinds of tea was potent and decreased generally with degree of feimentation. Inhibitory effects of tea extracts against angiotensin I converting enzyme were also potent.

The present study investigates the realization of tourism culture welfare by using Confucian heritage. From June 13 to November 7, 2014, site surveys and interviews were conducted for hyanggo (hyanggo: Confucian temple and school to teach students in Joseon Dynasty period), seowon (seowon: a memorial hall for Confucianist services to honor distinguished scholars and statesmen) and nujung (nujung: outdoor pavilion or gazebo) located in Youngwol -gun. Questionnaire pertaining to site survey and in-depth interviews for the building owners and managers was used to collect necessary data and scientific investigation was performed for analysis. As a result, the historical background was found to be culturally valuable asset for both region's tourism and culture welfare. Secondly, hyanggyo and seowon were found to exhibit traditional Confucius cultural form, while nujung exhibited a rare architectural trait. Hence it seems necessary to develop a different social tourism resource specialized for nujung. Thirdly, the rendering of Confucius heritages to tourism culture welfare resources thus far seems to be insufficient; hence, development and operation of marketing programs will be necessary. The implications of the present study require succession and modern reinterpretation of Confucian heritages for further development into digital tourism that will encompass Confucian culture and today's culture. Furthermore, studies of the tourism culture welfare policies that will promote the co-existence with the region will be needed.

The most serious problem company facing in today's business environment is the failure of new product development outcomes. Statistically, almost half of the new products released each year failed. Despite the innovative technological advances, consumers' expectation level become much higher and global competition is intensifying. In addition, the new product life cycle is becoming shorter and shorter. It is difficult for a company to survive without developing long-lived products. The most important issue in a company's success and failure is the successful development and introduction of new products. Previous research has presented many determinants to achieve a successful new product development. This study focuses on dynamic competence as an important determinant, and identifies the constituting elements. Enterprises need to acquire, absorb, integrate and reconfigure their resources to survive and develop continuously. It is necessary to hold a dynamic ability switching resource bases in order to adapt to changing environments. The results of this study are as follows: First, the effect of learning, reconfiguration, and alliance capabilities on the new product development of small and medium-sized manufacturing enterprises seems to be positive. Second, the integrative and reconfiguration capabilities positively affect a new product development under high environmental turbulence.

This study is about the historical records of anchovy which has fluent nutritions as well as the representative side dish in Korean food culture and life. The formal first record about anchovy is in the Uhaeieobo written by Damjeung in 1803. Another important historical record about anchovy are Hyeonsaneobo(Jasaneobo) written by Jeong Yak-jeon in 1814, and Eomyeonggo(Fish name list) of Nanhoeomogji written by Seo Yu-gu in 1820. The anchovies were used for food in Korea even before the Chosun Dynasty, but they were not noticed by people. Because at that time, fishing tools and instruments such as nets were not developed enough to raise enough catches and food processing technology were not developed. Since then, in the Japanese colonial era, it has been actively developing agricultural fertilizers using anchovies. In addition, the processing technology that can be used as an edible food using anchovy has been rapidly developed. Now, the anchovy industry has very important position in Korea's fisheries industry. Among them, 'Jukbangryum anchovy' catching bamboo weir tool which has been existed for over five hundred years in Namhae province, not only creates great high economic value, but also has cultural value. Therefore, the historical literature study on anchovy can be used as an invaluable resource not only for the study of fishery from an industrial point of view, but also for the registration of world cultural heritage and GIAHS (Globally Important Agricultural Heritage System) of 'Jukbangryum' which is traditional fishery catching instrument in Korea.

In the modern urban landscape design, historical and cultural factors are drawing more and more attention in addition to the factor of beauty. To evaluate an urban landscape design, it's quite important to explore the history and culture background of the city. Color of a city reflects the city characteristics and shows the city image. Color planning has become an important part of city landscape design nowadays. A harmonious landscape cannot be without a unified color planning. The color planning should take not only the integrity but also the regionality into consideration. Color planning has a profound impact on public life. This paper studies on streetscape color of two famous places which are Seoul Insa-dong and Shanghai Xintiandi. According to the empirical and comparative study, this paper will give on-site assessment and comprehensive evaluation. Furthermore, this paper will indicate the differences and similarities of the traditional Streetscape of South Korea and China, using the color theories of Korea Image Resource Institute. This survey results will be helpful to the urban landscape color planning.
