        이 논문의 목적은 몽골 농업의 연구 현황과 과제를 파악하 는 것이다. 몽골의 농업 분야는 몽골 농촌에서는 문화 그 자체이며 농촌 가구 고용의 핵심 동력이다. 하지만, 몽골 농업 분야는 1990년대에 몽골이 자유시장 경제로 체제전환을 하면서 오히려 성장 동력을 잃고 있다. 특히 몽골 농업 연구에 관한 투자가 매우 낮은 수준에 머물러 있는 동안 농업 분야 종사자와 연구진 사의 간극은 더 커지고 있으며 농업 분야의 연구 투자가 이러한 격차를 좁히는데 기여할 뿐 아니라, 몽골 농업의 성장 동력을 다시 회복하는 데 기여할 것이다.

        Microtextural and surface chemical heterogeneities of activated carbons (AC) have been studied to see their distinctive role for the adsorption of CO2, CO and N2 at 25 °C and up to 850 Torr. Not only the microtextural properties influence the adsorption of the gases, particularly CO2, but the chemical surface heterogeneity also plays a significant role for CO2 adsorption. The volume of ultramicropores < 7 Å is of predominantly importance in high CO2 adsorption at pressures above 30 Torr. However, the average size of micropores and their size distribution, and the chemical surface heterogeneity are much more critical at the Henry’s law region (< 30 Torr). The latter could be well characterized by the amount and Henry constant of CO2 adsorption at the low pressures, the Toth model parameters, the change in CO2/ CO and CO2/ N2 selectivities with respect to pressure, the amount of CO from the thermal decomposition, and the direct probing of very strong basicity sites using a technique that is the temperature-programmed desorption of CO2 adsorbed. All of them are consistent with the difference in the energetic nonuniformity between ACs studied, except for the last measure whose results could be reasonably explained when combining with the microtextural heterogeneity.

        Although the white-spotted flower chafers beetle, Protaetia brevitarsis, receive attention to explore useful active ingredient for the preventive effect of liver-related diseases, little is known about cosmetic effect. Here we report that the larva extract of the white-spotted flower chafers has functional cosmetic effect using the B16F10 melanoma cell and HaCaT keratinocyte cell. The ethanol extract of hot-air dried P. brevitarsis larvae showed the inhibitory activity of tyrosinase (an enzyme that regulates the melanin production) and remarkably inhibit melanin biosynthesis in the B16F10 melanoma cell. Further, the ethanol extract induced the expression of hyaluronic acid synthetase (HAS2/HAS3), which produce hyaluronan related to epidermal structure, and indeed increased hyalurona in HaCaT keratinocyte cell. Consequently, P. brevitarsis could be new functional cosmetic material for whitening and moisturizing effect.

        The structural diversity and localization of cell surface glycosphingolipids (GSLs), including gangliosides, in glycolipid-enriched microdomains (GEMs) render them ideally suited to play important roles in mediating cell recognition, adhesion, interactions, receptor function, and signaling. Gangliosides, sialic acid-containing GSLs, are most abundant in the nerve tissues. The quantity and expression pattern of gangliosides in brain change drastically throughout development and these changes are mainly regulated through stage-specific expression of glycosyltransferase genes. However, roles of gangliosides in neuronal differentiation of mesenchymal stem cells (MSCs) is unclear. We previously demonstrated for the first time that the glycosyltransferase genes during mouse embryogenesis. So, we investigated the effects of ganglioside gene in differentiation of adipose-derived MSCs (AD-MSCs). GM2 and GD3 ganglioside synthease were increased during neuronal differentiation of AD-MSCs. This study showed that the differentiation of neuronal marker was decreased on the first step of ganglioside synthase UDP-glucose ceramide glucosyltransferase(UGCG) and knock downed GM2 sythase (B4GALNT1). The result of suggested that GM2 and GD3 might be important roles in the neural differentiation of mini-pig AD-MSCs. This work was carried out with the funding of the cooperative research Program for Agriculture Science & Technology Development[Project No. PJ00999901], the Rural Development Adiministration, the KRIBB Research Initiative Program[KGM4251622].

        Diversity and distribution of entomopathogenic nematodes were surveyed in Korea from 2010 to 2014. Soil samples were examined for the presence of steinernematid and heterorhabditid nematodes by baiting method with Galleria mellonella larvae. Out of the 189 soil samples, 47(24.9%) were positive for entomopathogenic nematodes, with the share of 7(3.7%) for Heterorhabditis and 40(21.2%) for Steinernema isolates. Morphological and molecular studies were also utilized to characterize isolates. The Heterorhabditis isolates were identified as H. megidis and Steinernema isolates as S. carpocapsae, S. monticolum and S. kraussei, respectively. H. megidis was the most common species of Heterorhabditis, which was isolated from 7 sites across the five different provinces and Steinernema monticolum was the most common species of Steinernema, which was isolated from 34 sites, respectively. S. carpocapsae was isolated from only two sites, Namwon, Jeongnam province and Iksan, Jeonbuk province, respectively. S. kraussei was the first recorded entomopathogenic nematode in Korea. Those entomopathogenic nematodes were recorded from coniferous and deciduous forests.

        Various insect pest damage agricultural crops and forest. Several control strategies have been tried against these pests. Using chemical pesticides is one of the major control strategies. However, in recent years, eco-friendly control measures have received a big attention. Entomogenous nematodes are best known as potential biocontrol agent which are promising alternatives of chemical pesticides. During the survey of insect-parasitic nematodes as well as their parasitism in Korea, three new species, Parasitylenchus cyrtogenii n. sp., Parasitylenchus oscavus n. sp., Bathymermis sancheongensis n. sp. and seven other new records for the Korean nematode and nematomorpha fauna were identified, which are: Howardula phyllotretae, Parasitaphelenchus uncinatus, Hexamermis albicans, Hexamermis sp., Heterorhabditidoides chongmingensis, Pristionchus pacificus, and Spinochordodea tellini, respectively. Parasitism of nematodes ranged from 0.7 to 87.5%. The highest parasitism was recorded in P. cyrtogenii n. sp isolated from Cyrtogenius brevior as 87.5%, however the lowest parasitism found in Hexamermis sp. isolated from Oxya chinensis as 0.7%.

        Parasitism of horsehair worm in mantids were investigated for two years, from 2012 and 2013. The mantids were collected from forty-nine sites from August to November. Twenty-one sites (42.9%) of the collected mantids were parasitized by horsehair worms. C. japonensis was recorded from T. angustipennis, T. aridifolia and C. fukuii. The C. japonensis parasitism of T. angustipennis and T. aridifolia were 27.0% and 10.7%, respectively. The infested number of C. japonensis was 1-9 per host. The body length of C. japonensis showed tendency to decrease with number of parasites, but not significantly different. Horsehair worms did not affect body, abdomen length and digestive system of host. However, egg possession of host was different, unparasitized T. angustipennis and T. aridifolia had more eggs (63.7%) than parasitized ones (2.6%). C. japonensis was parasitized as immature stage in late Aug. immature and adult stage in early Sept. and only adult in late Oct. Parasitism was the highest in late Sept.

        The information technology has affected many aspects of retail world as in other areas of human life. This makes understanding consumers’ acceptance and usage of such technological innovations a critical task for both retail businesses and scholars alike. The technology acceptance model (TAM; Davis 1989) is one of the most widely adopted theoretical frameworks for explaining and predicting consumers’ acceptance of technology. Implementing the meta-analysis method, this study aimed at testing the validity of TAM for understanding consumers’ attitudes and behaviors toward the various technologies adopted in fashion retail stores and online commerce sites. Specifically, the effect sizes of two TAM antecedents of perceived usefulness (PU) and ease of use (PEOU) were estimated and compared. Moderating factors that affect the effect sizes of PU and PEOU on attitudes and behaviors were also explored. A meta-analytical SEM methodology was expected to deliver more thorough and valid test of the model than single sample studies, because accumulation of multiple samples through meta-analysis would bolster the test's statistical power (Hom et al., 1992). A sample of studies on consumers’ acceptance of retail technology in fashion retail context that adopted the TAM model were collected through a systematic search through the databases such as EBSCO, Google Scholars, and Dissertation Abstracts. Efforts were made to include unpublished studies to avoid publication bias. A total of 31 published and unpublished research reports that allowed the calculation of effect sizes of the key paths in the model were included in the final analysis. The effect sizes were calculated out of the identified samples, and the homogeneities of the effect sizes were tested using comprehensive meta-analysis software. The types of technology, product type (apparel vs. general merchandise), subject characteristics (gender; country; student vs. general), and study setting (actual experience vs. simulated situation) were considered as moderators to explain for the variances in correlations among variables. Finally, a meta-SEM model was tested on the aggregated data using AMOS.

        Backed by the rapidly-growing economy, China sends the most tourists to Korea. Accordingly, growing consumption of Chinese tourists is strongly drawing attention of the Korean retail industry. Academia has conducted more relevant researches, such as effective branding of Korean Wave, and services to attract tourists. Despite a series of efforts, including specialized tour products and language services, there have been an increasing number of Chinese visitors complaining about their experience in Korea and Chinese tourists are urgently demanding improvements. Hence, comprehending sophisticated consumption behavior of Chinese tourists is becoming more important than ever before. Also, it needs to explore how shopping experiential value that they experience while purchasing fashion goods in Korea affects their satisfaction of the store and product. Previous literature has shown that perceived shopping value has a positive effect on customer satisfaction and behavioral intention (Mathwick et al., 2001). Previous domestic studies that targeted Chinese tourists have focused on investigating the shopping motivation and satisfaction (Ko, 2011) and market segmentation of Chinese tourist shoppers (Oh, 2014). Previous studies have approached this problem mainly from its cognitive aspect and few studies have focused on the emotional aspect during shopping. This study suggests that emotional behavior mediates the relationship between shopping experiential value and consumer attitude toward products and stores. According to the Korea Tourism Organization, the ratio of male to female Chinese tourists visiting Korea changed from 69:31 in 1995 to 59:41 in 2005. In 2013, female Chinese tourists outnumbered males at a ratio of 41:59. The number of Chinese female tourists continues to increase. Females are known to be more involved in fashion consumption. Hence, this study is conducted on 550 Chinese female tourists who have shopping experiences during their visit to Korea. The ages of the respondents range from 20 to over 50 years old, with a mean age of 33.5 years. Their shopping experiential value is measured by visual appeal, crowding, economic benefits, and service excellence, and is expected to trigger emotions of entertainment and escapism. Variables including entertainment and escapism are measured using the Experiential Value Scale developed by Mathwick et al. (2001). This study finds that three experiential values (visual appeal, crowding, and service excellence) have positive influences on entertainment. For example, customers feel greater entertainment when visual appeal, service excellence and/or the number of customers in the store is greater. The emotion of entertainment turns out to have positive impacts on both store satisfaction and product satisfaction. According to the examination of how shopping experiential values affect escapism, crowding and economic benefits have a positive impact, whereas visual appeal and service excellence have a negative impact on escapism. Previous studies define escapism as an emotion of which customers are absorbed by entertaining activities and satisfied with shopping. This study assumes that all the shopping experiential values may have a positive impact on escapism. Escapism is a status where customers are deeply occupied with shopping without thinking of anything as if they were in another world, and a much stronger emotion of entertainment than usual pleasure from shopping. This study finds that the higher visual appeal and service excellence tends to generate the lower the escapism. This may be attributable to the fact that the survey was examined only on Chinese tourists. The respondents were asked to recall the most memorable item among the fashion products that they purchased during their visit to Korea. Their shopping experiences varied widely from well-organized malls, like department stores and duty free shops, to crowded environments, like Dongdaemun, traditional markets and subway stores. As a result, different experiential values have different impacts on escapism. Economic benefits and crowding which are experienced during shopping help to absorb in shopping, and these are likely to have positive impacts on escapism. On the other hand, visual appeal and service excellence may have different influences on escapism according to the shopping environment that Chinese consumers experienced. For example, Dongdaemun or subway stores are less visually appealing than department stores or duty free shops, but trigger stronger sense of escapism. Because survey questions to measure service excellence include Chinese (language) proficiency of sales staff, it is expected that higher language proficiency level of sales staff tends to generate lower degree of escapism, the sense of feeling that one is indeed in foreign country like Korea, for customers. Escapism has negative impacts on both product and store attitudes. Escapism is a status of absorption in which customers are emotionally occupied with pleasant feelings, and purchases along with a high escapism are likely to be less rational and more impulsive. In particular, this study examines tourist shoppers, and the respondents evaluate products they purchased in another country after they return home, and this may have caused the negative attitude toward products and shops. In fact, some previous studies found that overly positive emotions have negative impacts on purchase behavior (Liljander &Standvik, 1997; Andrade, 2005). This study confirms that the shopping experiential values perceived by Chinese tourists affect their product and store attitudes through the emotions of entertainment and escapism. It is particularly notable that this study verifies diverse roles of different emotions such as entertainment and escapism in the context of tourist shopping. This study employs empirical analysis on tourists, and provides practical implications including the importance of shopping experiential values for developing retail strategies.

        The influence of tourists on the retail market continues to grow and China is destined to become the largest outbound-spending nation in the world; subsequently, the interest on Chinese tourists has increasingly grown. The advancement in information technology and increased usage of SNS allows Chinese tourists share a variety of information online before or after they embark on to others. Data from the Korea Tourism Organization indicates that, “shopping” is the most searched keyword for Korean tours in 2014. The main shopping item of Chinese tourists is fashion or beauty products and we need a better understanding of the consumption behavior of Chinese tourists in relation to Korean fashion. We should consider shared content by Chinese consumers to promptly respond to needs and concerns. This study researches actual attitude of Chinese consumers toward Korean fashion items and shopping tourism using content analysis based on Chinese SNS. We investigate the representative portal search site Baidu (百度) and Weibo (微博) SNS primarily used by Chinese. Our investigation is limited to posts or comments one month before and after China’s National Day. Our analysis used translations of Chinese into Korean. A total of 70 words were selected based on the mentioned frequency by R Program forthe final analysis. Words were divided into groups based on content analysis similarity and word connectivity was researched using the Net Miner program. A total of 70 words used for the analysis were divided into three groups: shopping item, shopping behavior, and shopping place. The relevance of content to shopping item accounted for 39% and most of the shared information was about where to find cheaper items, various styles, or the latest fashion products. Shopping behavior accounted for 17% and the shared information was about how to compare products before purchase, how to communicate with salespersons, and how to obtain refunds after purchase. Shopping places area dominant group with 43% and half of the words about retail trade. Significant information was available on the main characteristics of retail trade areas such as Dongdaemoon market or Myeongdong. More information was shared on underground shopping centers or general road shops than on traditional shopping places, department stores, or duty free shops. The trends are particularly notable and help in understanding how Chinese tourists are more interested in shopping places where they can have new experiences. This study confirms the shopping behavior of Chinese tourists in Korea using content analysis of Chinese SNS. The shopping trend changes; the average Chinese tourist age drops and the Chinese tourist pattern shifts from large group tours to individualized small group tours. Appropriate responses to Chinese tourists must be based on understanding of their changing shopping needs. This study is useful to understand the actual attitudes and needs of Chinese consumers toward Korean fashion based on shared online content.

        With the sweeping popularity of Korean Wave across Asia, the number of Chinese tourists to Korea has rapidly been increasing over the last decade. Korea Tourism Organization estimates that the number of Chinese visitors exceeded 6 million in 2014, and Korea Institute for Industrial Economics and Trade estimates that their spending in Korea surpassed KRW 7.67 trillion in 2013 alone. In particular, Chinese tourists spend most of their money in Korea on shopping. Since Chinese have become the major customers of the Korean market, it is critical to understand their consumption patterns and behavior. Previous studies looked into tourist destinations and shops that Chinese people frequently visited, and also researched on product selection criteria regarding their preference on fashion products. However, this study focuses on how Chinese tourists feel while they are shopping in Korea and how such emotions affect their evaluation on the purchased products. Planned purchase refers to the situation where the buying intention of a consumer has already been formed prior to entering the store based on the perception of purchase necessity. An unplanned purchase is not anticipated or planned before the customer enters the store, and products are bought without planning similar to impulsive buying. Oliver (1980) suggested that emotions are an important factor when consumers evaluate a product. Therefore, this study focuses mainly on the emotion created during the shopping. We conceptualized product attitudes based on the expected consumer satisfaction paradigms of Oliver and Desarbo (1988). This study also explores the product usage satisfaction of tourists as a post-purchase attitude. According to statistics, majority of Chinese tourists who buy fashion products are women. The survey is conducted on 550 women in the age group between 20 and 60 years who have visited Seoul before, using an online panel of respondents sampled by an international survey firm. 530 questionnaires are analyzed, with the remaining responses determined to be incomplete. For the demographic characteristics of the sample group, the average age is 33.5 years old, with 201 in their 20s (37.9%), 190 in their 30s (35.8%), 107 in their 40s (20.2%), and 32 in or over their 50s (6.0%). As for the average household income, RMB 10,000 to 20,000 is the most frequent (210 or 39.6%). For residential areas, Hua Dong (East China) is the most frequent (207 or 39.1%). Data are analyzed using structural equation modeling by AMOS 20.0. Respondents were asked to recall most impressive fashion product that they bought in Korea during their visit, and to answer whether it was planned or unplanned purchase.This study also attempts to measure the emotions they had during the purchase in order to understand differences in attitude toward the purchased products. Although emotions cannot persist over time, previous studies have measured emotions during consumption to evaluate the situation. The study categorizes respondents according to their purchasing power into heavy and light buyers to determine the moderating effects of purchase amount. In the literature, purchasing power is described in terms of the number of purchase and purchase amount. Based on previous studies on purchasing power, consumers can be categorized as heavy or light buyers. This study focuses on purchase amount in the context of tourism shopping. The results find that planned purchases tend to deliver positive emotions, which in turn enhances product satisfaction. Unplanned purchases, positive shopping emotions have positive impact on their attitude toward purchased products. Interestingly, unplanned purchases have negative direct impact on the product attitude without the mediating role of positive shopping emotions, showing the importance of positive emotions that consumers feel while shopping When it comes to the impact of purchasing power, the effect of unplanned purchases of light buyers on shopping emotions or product attitude was not significant. Only planned purchases trigger positive emotions, many of which induced positive impact on product satisfaction. For heavy buyers, on the other hand, even unplanned purchases have positive impact on their product satisfaction when positive shopping emotions are developed. This study is differentiated from previous studies in that it deals with how purchase types (planned vs. unplanned) affect shopping emotions and post-purchase product attitude of Chinese tourists who account for the significant share of the Korean tour industry. It is also notable that this study groups tourists by their purchasing power and identifies the impact of their purchasing power, considering the fact that tourists are increasingly influencing the domestic consumption market. The Korean government and companies may tap into the results of this study to provide better environments to trigger positive shopping emotions to tourists. However, it should be considered that the subject of this study is limited to Chinese female tourists, which should be complemented by future studies.

        Horsehair worm parasitism of mantids was investigated for two years, 2012 and 2013. The mantids were collected from forty-nine sites from August to November. Mantids collected from twenty-one sites (42.9%) including Amur silver grass plantation at Samjang-myeon in Sancheong, Gyeongnam province were parasitized by horsehair worms. C. japonensis was recorded from T. angustipennis and T. aridifolia and C. fukuii, a newly recorded species in Korea, was isolated from T. aridifolia. C. japonensis was found from T. angustipennis and T. aridifolia collected from Gyeongnam province (Jinju, Sancheong, Sacheon, Uiryeong, Hapcheon, and Goseong) and Sangju, Gyeongsbuk province. C. fukuii was isolated from T. aridifolia collected from Gunwi, Gyeongbuk province and Yangpyeong, Gyeonggi province. The C. japonensis parasitism of T. angustipennis and T. aridifolia was 27.0% and 10.7%, respectively. The number of C. japonensis in a host was from one to nine, but most was one from a host. The body length of C. japonensis showed tendency to decrease with number of parasites, but not significantly different. Horsehair worms did not affect body and abdomen length and digestive system of host. However, egg possession of host was different, that is, unparasitized T. angustipennis and T. aridifolia. had more eggs (63.7%) than parasitized ones (2.6%).

        Amur silver grass, Miscanthus sacchariflorus is one of the promising biofuel crops. A damage of noctuid pest, Leucapamea askoldis was firstly observed from Amur silver grass in Hwasun silver grass plantation during the survey of insect pests of Amur silver grass in Iksan, Hwasun, and Sancheong plantation areas in Korea. The host of L. askoldis was not known yet in Korea. Thus, M. sacchariflorus was the first known host in Korea. The L. askoldis damage was observed as larval feeding on newly grown shoots of M. sacchariflorus close to soil surface from early April to early May in 2013. Investigated larval density was 1.6 ± 1.1 per m2 on April 4 and damage rate of shoots was 0.8% ± 0.4 per hundred plants on May 4, 2013. The larvae bore into shoots of M. sacchariflorus and then feed inside of plant. The damaged shoots are easily pulled out and distinguished by the boring hole on the shoots.

        Pine wood nematode (PWN), Bursaphelenchus xylophilus is associated with the pine wilt disease and transmitted by pine sawyer, Monochamus alternatus. Because pine sawyer has one-year life cycle, one natural infection of PWN is occurred a year. Therefore, artificial propagation method of PWN is needed to improve experiment associated with PWN. In this study, effect of diameter, paraffin sealing of twig and dosage on pine wood nematode reproduction in Japanese black pine, Pinus thunbergii. PWN reproduction was compared in twigs of P. thunbergii and P. densiflora. Numbers of reproduced PWN were higher with decreasing diameter of twig. Distance (5 and 10 cm) from inoculation site of PWN did not influence reproduction of PWN. Reproduced numbers of PWN were higher in the paraffin-sealing twig than non-sealing twig. Dosage of PWN influenced reproduction of PWN. Reproduction rate was the highest at the rate of 10 IJs (13.7 and 61.1-fold increasing in P. densiflora and P. thunbergii, respectively 30 days later) whereas lowest at the rate of 1000 Ijs (1.1 and 0.7-fold increasing in P. densiflora and P. thunbergii, respectively 30 days later). Numbers of reproduced PWN were more in P. thunbergii than P. densiflora.

        동해 표기를 둘러싼 갈등의 문제를 동해 수역이 갖는 지정학적 의미로부터 살펴보고 그 해결책을 찾아보는 것이 이 논문의 목적이다. 태평양의 연해로서 공산주의와 자본주의 세력이 대립한 최전방으로서의 입지적 특성, 환동해 지역경제권의 등장, 동해를 둘러싼 네 개 국가의 정치적 이해와 대립 등의 요인들이 이 지역에 지정학적인 영향력을 끼쳐 왔고, 이것은 영유권, 경제수역의 경계 획정, 그리고 표기 문제의 갈등으로까지 진전되어 왔다. 여기에 지명 표기가 갖는 독특한 정치적 의미가 더해져 동해 표기 문제는 여전히 해결되지 않는 문제로 남아 있다. 현재 동해/일본해 표기에 관한 양측의 주장을 고려할 때 세 가지의 해결방법이 가능하다. 새로운 제3의 이름에 합의하는 것, 두 개의 이름을 동시에 사용하는 것, 바다를 분리하여 분리된 바다에 각각의 이름을 부여하는 것이 그것이다. 그러나 어떤 해결이라도 각국의 정치적 결단이 없이는 불가능하다는 점을 고려해야 한다.

        Dipterans are excellent insects to serve as forensic indicators to determine the postmortem interval of a human corpse. Therefore, we undertook a study to identify the major dipterans that are attracted to and develop in vertebrate carcasses. To determine what dipterans occur in Korea, chicken carcasses were placed in various habitats including the forest, open field, stream bank, greenhouse, rooftop, rice paddy, Chinese cabbage field, vacant hut, and pond at different times of the year. The dipterans were collected at various time intervals after placement in each habitat until the end of decomposition and identified. Our results showed that 49 identified and unidentified dipteran species from 36 genera in 19 families were collected from the carcasses. Habitat placement influenced the number of species isolated from the carcasses. For example, 39 species were collected from the forest habitat, 28 species from the open field, stream bank, or greenhouse each, 16 species from a vacant home, and 12 species from the pond. The dipteran species that were collected from all habitats were Phaenicia sericata, Lucilia illustris, and Lucilia sp. in the family Calliphoridae and Boettcherisca peregrine in the family Sarcophagidae. Other dipteran species that were isolated depended on carcass placement that is, fewer dipteran species were observed from carcasses in the backpack and much more species were recorded from unburied carcasses than buried carcasses.
