Due to the large amount of beef imported from the USA to Korea, Korean consumers have become increasingly interested in the country of origin since it can affect market prices. Previously, Bos indicus and Bos taurus-specific markers were developed for the purpose of cattle breed identification, specifically discrimination of Australian beef. In this study, six SNP markers derived from Illumina 50K bovine SNP chip data were used for the discrimination between Korean cattle (Hanwoo) and imported beef from USA. PCR-RFLP genotyping methods were also developed, which indicates that these markers can be applied relatively easily compared to other markers. Taking into account a discrimination rate of 55% based on MC1R marker between Hanwoo and imported beef from USA, two additional markers, SNPs 23803 and 34776, were ideal and resulted in probability of identification of 0.942 and probability of misjudgment of 0.03. Therefore, the markers developed in this study can greatly contribute to the correct discrimination between beef from USA and Hanwoo beef.

This study was conducted to determine recognition of Chikhanwoo, promote its market competitiveness, and vitalize its uses in Korea. This research was carried out on 465 people, including 264 of the general public and 191 livestock farmers. For awareness of Chikhanwoo, 53.6% of the general public and 86.9% of livestock farmers recognized Chikhanwoo (P<0.001) through TV, Internet, news, magazines, and others. For consumption behaviors of Chikhanwoo meat, 4.3% of the general public and 1.9% of livestock farmers have purchased Chikhanwoo meat in the past. Most of them hinted at their intention to repurchase and highly intimated their wish to purchase on whether Chikhanwoo tastes better, is more nutritious and is safer than Hanwoo. In addition, they thought country of origin and price were the most important factors for purchasing (P<0.001). For recognition of the Hanwoo grading system, they preferred $1^{{+}{+}}$ and $1^+$, significantly (P<0.001). For need for quality certification, most respondents thought that the government should introduce a quality certification system for Chikhanwoo. For importance factor of prevalence of Chikhanwoo meat, marketability value had the highest degree of importance, followed by taste, quality, tradition and cooking methods (P<0.001). Results of this study show that domestic consumption of Chikhanwoo can be boosted by supplying Chikhanwoo meat with a differentiated taste and a safety assurance to the general public. There is also need to enhance genetic resources and improve brand value of Chikhanwoo. Continuous research and efforts should be made for the development of the livestock market.

I referred to documents to study the origin and the progressing process of textiles. Cotton seeds were first imported from China by Mun, Ik Jem at the end of the era of Koryeo, and cotton had several different names such as mok-myen, cho-myen, gil-pae, baek-chep-za, tap-po, ban-ki-wha, dong-yep-po and so on. Since the era of the Three Kingdoms, people had heard of cloth of superior quality but it was not certain whether it was imported from China or made in our country. It seems that cotton was not made during that period, white silk, hemp cloth, and ramie fabric were produced. At that time, linen was called cotton by mistake. After importing cotton seeds from China, all the people began to plant them and made their clothes from them. At the beginning of the Yi Dynasty, the weaving technique was dependent on China. However, the government persuaded farmers to plant them. At that time cotton was used as a means of purchasing instead of money. Silkworms raising started during the era of the Three Kingdoms and it was widely spread at the beginning of the Yi Dynasty. In order to encourage sericulture' spinning and weaving instruments were installed in the royal palace and the queen with sher court maids demonstrated how to spin and weave. The activity was named "chin-jam-ye." Linen was the representative of all textiles and it was also very popular. The technique of weaving had already been highly developed at the era of Silla. During the era of the Three Kingdoms people used "bang-chu-cha" as a weaving instrument. They discovered several new hand machines in the period of the Yi Dynasty: they were instrument of removing seeds, spinning wheel, hemp cloth loom and so on, and we find the remains of them these days.

An exotic parasitic wasp Anisopteromalus apiovorus of Pteromalidae was newly recorded in Korea. Specimens of this species have been collected in Gimhae of Korea since 2012. External morphology of this species was described in detail and diagnostic differences of this species from the related species and the host insect were also given. The funicle segments of female antennae are 1.2 to 1.5 times longer than those of Anisopteromalus calandrae, an sister species. Body color is gold-glossy black and with dense creamy-white hairs on the surface. This exotic species has been originated from the African continent including Democratic Republic of Congo and Cote d'Ivoire, and then intruded into other countries, for instance, Korea. This is the first distribution record of this species except the country of origin after original description as a new species. Although little is known about the life history or ecology of this species, we found that a new host of this small parasitic wasp is Lasioderma serricorne of coleoptera through present study. And this species possibly be a new agent of biological control for economic pests. It was presumed that the invasion of Anisopteromalus apiovorus into Korea was prior to November of 2012.

The Purpose of the study was to compare clothing shopping motives, fashion information sources, evaluation criteria of apparel products, store selection criteria, apparel buying places, and purchasing experience and country of origin place on imported clothing. The total of 371 consumers, college female students in Korea and Japan were sampled in both countries. ANOVA, factor analysis, Duncan's multiple range test, t-test, frequency, and percentage as analysis methods were used. The results of the study were as follows. According to the comparative analysis of clothing purchasing behavior by factors, the result showed that both of them had more personal motives than social ones, regarding clothing purchasing motives. The clothing purchasing motives of students in Korea was higher than it of students in Japan. In the use of information sources, the students of both countries considered the information by consumer very importantly. Next to it, they highly regarded the information by marketer. The students in Korea used all informations more than the students in Japan. In the clothing selection, both of them considered criteria esthetics very importantly. The students in Korea considered 'brand name', 'versatility', and 'pleasing to others' as important, but the students in Japan considered 'price' and 'prestige' very importantly. For store selection criteria, Korean students considered 'duality guaranteed', 'service', and 'their and other's experience' as important but Japanese students regarded 'price' and 'variety of products' as important. A department store was the most highly preferred among clothing purchasing stores. After it, for Korean students, fashion mall, renowned brand stores, discount store were considered in order of preference, for Japan, speciality stores, fashion mall, renowned brand stores are preferred. Regarding imported clothing, Korean students, in order of preference, preferred the goods of America, Italy, France, England, etc. Japan students preferred the goods of America, Italy, China, France, etc.

Recent trends of global food production, processing, distribution and preparation under free trade circumstance are creating an increase in common' concerns about food safety. It is important that farmers improve agricultural products/food safety for satisfying consumer needs and health. Cognizant to the situation, this study was conducted to analyze how the Producers gather information, and determine their awareness about agricultural Products safety using a safety Questionnaire. The Questionnaire was given to 500 farmers who cultivate rice, fruit trees, vegetables, and other crops from September through October 2005. More than half of the producers felt concerns about the agricultural products/foods safety. Uneasiness of the producers was higher amongst those who were younger and earned a higher income. Pesticides and zoonosis (BSE AI, etc.) emerged as the main risk factors causing concerns among the greatest number of producers. Producers had a positive opinion of the effects and perception of food safety, but no opinion of the activity of government. The producers showed a high level of understanding of the Country of Origin Labeling System (88.2%), the quality certification system of agricultural and livestock products (71.9%), and the raising system of environment-friendly agriculture (72.7%). However, their level of understanding of the GAP (59.3%) and the Traceability System (22.8%) was still low. To effectively implement these policies, awareness of producers who are the beneficiaries of the above policies has to be enhanced. Therefore, the safety information should be provided at a more appropriate time and should be easier to understand.

Invasive alien plants were identified and recorded in Ulsan city based on field surveys and related literatures. These plants consisted of 147 taxa in total, belonging to 30 families, 93 genera, 144 species, 2 subspecies and 1 variant. The family of Asteraceae was predominant with 42 taxa, followed by Gramineae with 27 taxa and Leguminosae with 15 taxa. According to the result of life-form based distribution analysis revealed that 62 taxa (42.2%) were annual plants, 48 taxa (33.6%) were perennial plants, 34 taxa (23.1%) were biennial plants, and 3 taxa (2%) were woody perennials. Compare to other administrative districts in Korea, prevalence of invasive alien plants in a certain city of Ulsan showed the seventh highest species number followed after Jeju, Gyeonggi, Jeonnam, Incheon, Seoul and Gangwon. On the basis of the results from the country origin analysis, two dominating taxa were introduced from Europe and America, 55 taxa and 51 taxa respectively. The spreading grade of alien plants was elucidated in order of 1 grade (PS) 67 grade (21.1%)>2 grade (MS) 31 taxa (21.1%)>5 grade (WS) 18 taxa (11.6%)>3 grade (CS) 17 taxa (11.6%)>4 grade (SS) 14 taxa (9.5%). Ulsan city is one of a pivotal conduit for the introduction of invasive alien plants. Thereby, reliable management plans are required to monitor these species.

This study aimed to monitor the distribution of Cobitidae in Korea by the identification of species using genetic analysis. Based on the genetic analysis, Cobitidae species in four of five domestic fish farms consisted of only Chinese muddy loach Misgurnus mizolepis, but muddy loach Misgurnus anguillicaudatus was also present it in one fish farm. In the case of imported Cobitidae species, in addition to Chinese muddy loach and muddy loach, the harmful species Paramisgurnus dabryanus, was also present. Chinese muddy loach accounted for 20%, 67%, and 60% of the S6, S7, and S8 samples, respectively. An analysis of the total length, body length, and weight showed that domestic Chinese muddy loach showed higher values than imported muddy loach, and imported Chinese muddy loach showed similar values to P. dabryanus. There were no significant differences in the country of origin of the three species. Thus, the mitochondrial cytochrome c oxidase subunit I gene sequence was analyzed and compared the verification of species identification. The three species of Cobitidae were genetically divided into three groups and determined to have genetic differences. These results indicate that it is necessary to reduce the heterogeneous mixing rate through discriminating species by genetic analysis.

Objectives : This study aims to investigate the current situation of domestic patents in Korea on natural products and to provide directions for developing and applying herbal medicinal products by in-depth analyses. Methods : Combinations of words, such as "A61K" or "A61P", "herb" or "Korean medicinal herb" or "Korean medicine" or "traditional" or "natural" or "$botanic^*$" or "China", and "medicine" or "treatment" or "prevention" or "improvement", were used to search patents in the World Intellectual Property Service (WIPS) database. Three methods were applied to analyze natural products patents. First, the number of patent registrations was sorted by year. Second, the assignees were analyzed by count and country of origin. Finally, cluster map analysis was conducted to explore frequently emerging words in natural products and the relationship amongst those words to treat corresponding diseases/technologies. Results : Results showed that, first, the total number of patents had been increasing. Among the patents, 76.4% were registered by domestic institutes/companies, and 23.6% by foreign institutes/companies. Second, USA, Japan, and China possess a considerable number of Korean patents and, therefore, domestic institutes/companies can seek joint technological development opportunities with their counterparts from those countries in the future. Finally, a total of four clusters were identified by cluster map analysis. Each of the clusters includes natural products related to diseases involving skin, aging, and blood sugar, as well as adult diseases. Conclusions : In this study, natural products patents registered in the Korean Intellectual Property Office were analyzed. The analyses results showed the kinds of natural products that had been employed for the treatment of certain diseases. However, natural products included in existing patents were minimal given that 4,174 species of indigenous plants are found in Korea. Thus, Korean institutes/companies should utilize unexplored plants to develop more value-added drugs.
