Twelve garlic cultivars collected from Korea and Mongolia were evaluated genetic similarity and diversity by RAPD method using oligo-nucleotide random primers. Genomic DNA isolated from twelve garlic cultivars were amplified by polymerase chain reaction using 143 primers, and 55 primers showed polymorphic DNA bands. Among a total of 187 bands amplified by 55 primers, 128 polymorphic bands were subjected to analysis for genetic relationship of garlic cultivars. Garlic cultivars were classified into three groups, such as group-I corresponded to Euiseong, Seosan, Samchuk and Yecheon-A, Yechun-B, Euiseong-norang, Jeongsun, Namdo, Yookback and Danyang cultivars, and group-II to Mongolia and group-III to Daeseo cultivars. Thirty DNA bands showing unique specificity to the specific cultivars are likely to be useful for identification of garlic local cultivars as DNA markers.

Big data technologies are increasing the need for big data in many areas of the world. Recently, the health care industry has become increasingly aware of the importance of disease and health care services, as it has become increasingly immune to prevention and health care. To do this, we need a Big data system to collect and analyze the personal biometric data. In this paper, we design the biometric big data system using low cost wearable device. We collect basic biometric data, such as heart rate, step count and physical activity from Mi Band, and store the collected biometric data into MongoDB. Based on the results of this study, it is possible to build a big data system that can be used in actual medical environment by using Hadoop etc. and to use it in real medical service in connection with various wearable devices for medical information.

Agricultural tourism is a new kind of industry, which combined agriculture with tourism. It not only has the productive function, but also has the function of improving the quality of ecological environment and supplying people with sightseeing, leisure, vacation. Agricultural tourism is a new kind of industry from the amalgamation of agriculture and tourism: it is based on farm work, characterized by agricultural management, combines agriculture and tourism, and includes the city as a market-place. It satisfies tourist demand with food, lodging, excursions, shopping and entertainment provided by agricultural places and agricultural products. After combining the substance of this study with the primary sources regarding the development of agricultural tourism, I suggest plans for the development of local agricultural tourism on the basis of sustainable tourism theory in case of the Inner Mongolia region. To conduct research, various data such as literature research and surveys are collected and analyzed. According to the result of the research, the Inner Mongolia region has great-wealthy resources for agricultural tourism. However, they have problems as well such as lack of funds, low infrastructure, low business-mind level, low management-mind, the scarcity of mid-supporting organizations for research and education, low awareness, and low service level of the agricultural tourism. In order to solve these problems, have to strengthen publicity, strengthen the county and city communication, educates continuously profession talented person, establish related laws and regulations, increase the integrity of infrastructure. As a developing industry, agricultural tourism is a new field of study which needs more encouraging research. The agricultural tourism of Inner Mongolia Autonomous Region has only just started development resulting in a limited amount of information available for this study. Future planned work entails a continuous in-depth study of Chinese agricultural tourism, considering Inner Mongolia Autonomous Region in particular.

The phylogenetic relationships between Cheju native horses and Tsushima native horses were studied by protein polymorphism analyses in 16 gene loci (Trypsin inhibitor: Ti, Chymotrypsin inhibitor: CTi, Albumin: Al, Esterase: Es, Transferrin: Tf, Hemoglobin: Hb, Catalase: Cat, Esterase D: EsD, Glutamate oxaloacetate transaminase: GOT, Glyoxalase I: GLO I, Acid phosphatase: AcP, Superoxide dismutase: SOD, Lactate dehydrogenase: LDH, Hexokinase: HK, Malate dehydrogenase: MDH, Malic enzyme: ME). All allelic patterns of the protein loci, except 5 loci (SOD, LDH, HK, MDH, ME), were polymorphic in both two populations. Gene frequencies of the polymorphic loci of the population of Cheju native horses were higher than those of Tsushima native horses. Average heterozygosity in Cheju native horses was 0.375, showing higher than that of Tsushima native horses (0.304). The Da distance and gene identity of two populations were 0.108 and 0.868, respectively. The phylogenetic tree constructed by these results and those previously reported in other horse populations, consisted of three clusters. From this phylogenetic tree, it could be suggested that Cheju native horses and Tsushima native horses had diverged from the Mongolian wild horse (Equus prsewolskii).

Harderian glands are the unique organs in several mammals, which human and non-human primates do not have. We report the ultrastructural changes in the postnatal developmental periods of Harderian glands in Mongolian gerbil(Meriones unguiculatus). Male and female Mongolian gerbils were sacrificed on days 3, 10, 30 and 60 after birth and their Harderian glands were observed by transmission electron microscope. The obtained results were summarized as follows; 1. In 3-day-old Mongolian gerbils, Harderian gland was composed of one excretory duct and immature tubules which have two type cells, dark and light cells, identified electron-dense and electron-lucent respectively. 2. In 10-day-old Mongolian gerbils, small lipid vacuoles began to be found in the cytoplasm of the secretory cells of the Harderian gland. Mitochondria, Golgi apparatus, polysomes and slash were more abundant in the cytoplasm of dark cells than those of light cells. The arrangement of tubules in the gland was much more condensed than that of 3-day-old Mongolian gerbils. 3. In 30-day-old Mongolian gerbils, the secretory cells of the tubule were typically columnar in shape and there was one type cell in the tubule. Most of the columnar secretory cells contained various size vacuoles. 4. In 60-day-old Mongolian gerbils, the Harderian gland possessed the typical structural characteristics of adults. The mature glandular structures were more significant than those of 30-day-old animals.

This study focuses on the ideas that Chok-Du-Ri(족두리)ㆍHwa-Gwan(화관) are mentioned a substitute preventing abuses of luxury mood by Gache(가채) as the sharpest social problem at that time. First, the origin of Chok-Du-Ri(족두리) was introduced from Ko-Ko-Gwan(고고관) of Mongo(몽고) in Korea dynasty, then was linked to Chosun. That is, Ko-Ko(고고) started from headgear reflecting spiritual view of the northen people, its size was getting smaller passing through Ming(명) dynasty, its essential decoration changed and it carried out Jeon-Ja(전자) remaining decoration nature by real accessories, then it might be descended to Chosun. Second, Hwa-Gwan(화관) is very different from Nanaec(난액) of Chosun Dynasty Records, rather Jeonia, the original form of Chok-Du-Ri, is more similar to it. Third, its decoration like color, jewel, pattern etc influenced wishes of this life like sex, prosperity, glory, longevity, blessing, wealth and fame. Fourth, Chok-Du-Ri(족두리) was restored a substitute for Gache(가채), it was accessory for preventing luxury life, besides it was modeled from headgear in China, Chosun people had it. It is worthwhile as it was based on Chosun Sinocentrism(조선중화주의) in the latter period of Chosun and made it the fruit of that age. Moreover, in those days Qing(청) society accepted the advanced culture and institutional profit of Qing(청) actually, social mood is that home and overseas policy was corrected in many parts, Chok-Du-RiㆍHwa-Gwan were mentioned a substitute of Gache, symbol of luxury. It shows one part of Practical Thougth that abolishes vanity and affectation and makes useful profits in the latter period of Chosun.

This paper describes a design of an elliptic curve cryptography (ECC) processor that supports five pseudo-random curves and five Koblitz curves over binary field defined by the NIST standard. The ECC processor adopts the Lopez-Dahab projective coordinate system so that scalar multiplication is computed with modular multiplier and XORs. A word-based Montgomery multiplier of $32-b{\times}32-b$ was designed to implement ECCs of various key lengths using fixed-size hardware. The hardware operation of the ECC processor was verified by FPGA implementation. The ECC processor synthesized using a 0.18-um CMOS cell library occupies 10,674 gate equivalents (GEs) and 9 Kbits RAM at 100 MHz, and the estimated maximum clock frequency is 154 MHz.
