The rotifers collected from various terrestrial habitats such as mosses, lichens and mushrooms on tree trunks at four different locations in Korea were investigated. Five species and one subspecies belonging to four genera in three families of monogonont and bdelloid rotifers were identified: Adineta cuneata Milne, 1916, Macrotrachela insolita De Koning, 1947, Macrotrachela musculosa Milne, 1886, Macrotrachela nana nana (Bryce, 1912), Mniobia bredensis De Koning, 1947 and Bryceella stylata (Milne, 1886). All these rotifers are new to Korea, and A. cuneata, M. bredensis and B. stylata are new to Asia as well. Here diagnostic characteristics and illustrations are provided for each Korean new record.

This research was conducted to compare and analyze the effect of the space allowance on the productivity, behavior, and blood properties of Hanwoo in order to achieve the status of advanced country for the animal husbandry in accordance with global trends, and with the target of animal welfare production through the practice of environmentally friendly animal husbandry. Fattening cows (352kg) of an average of 43 months in age and with growing steers (225kg) aged six months were tested with two replications upon categorizing the animals into control group (8m2/heads) and treatment group (4m2/heads). Feeding was executed according to the prescription in the Hanwoo feeding management. The growth performances (BW, ADG, and FCR) were significantly improved in cow fattening as space allowance was narrower. Similar results were obtained from the growing steers. The behavioral characteristics of lying and walking were significantly higher in the control group (p<0.05), while standing was found significantly higher (p<0.01) in the treatment group. The lying duration did not show significant difference in the fattening cows. Meanwhile, walking time was significantly longer (p<0.01) in the control group among fattening cows whereas standing duration was significantly higher (p<0.05) in the treatment group. As for properties of blood component, the cortisol value was significantly higher (p<0.05) in the treatment group for the fattened cows. The experiment results imply that the space of 8 m2 / head would be adequate in the production of fattening cows and growing steers based on growth performances, behavioral characteristics, and blood component, and considering the space allowance per head in the pen. The results could be utilized as basic data for environmentally friendly and welfare type Hanwoo production system in the future.

Benzene was oxidized by binary oxidants composed of nitric acid and hydrogen peroxide at 80℃. The product obtained was analyzed with gas chromatograph-mass spectrometer.

This study will analyze the content of these laws on cooperativesand the characteristics of cultural content industry by examining why the cooperativesystem should be introduced. It will also analyze certain functions that cultural contentcooperatives perform and by doing so, will show that the industry can flourish when cooperatives in cultural content sectors are fostered and through this, a stable and sustainable business infrastructure can be created.

In modern society, the financial system has grown in importance. The financial system interchanges according globalization. China financial market is popular because it is great potential and has a large of customer. And Korea’s bank gets through china. It has trouble with going to china because of china’s regulation. But after joining WTO, china relaxes regulation. However, Korea banks have different thing some unique due to Korea bank’s customer has only business. So they emphasize service. Service includes not only kindness and high-quality job performance but also differentiation of space. Thereby, space is composed of simple moving line and easy business handling. This research studies about Architectural Planning Characteristics of Korean bank in China. In future this research would be basic material in architecture.

Oral exposure of humans by excess amounts of arsenic may cause disturbances of the reproductive system. In the present study, such exposure was modelled in rats, with the support of sperm principal parameters and histopa-thological observations. Male Sprague–Dawley rats were randomly divided into three groups where the group I was served as a normal control, group II was received sodium meta-arsenite as arsenic (10 mg/kg b.w/day) and a combi-nation of sodium meta- arsenite and sodium selenite (3 mg/kg b.w/day) in group III. After 6 weeks, there was no significant change in testis weight and in total motility of all the three experimental groups, whereas, rapid moving spermatozoa, moderately moving spermatozoa and slow moving spermatozoa were significantly decreased in arsenic treated rats as compared to control rats. The other sperm principal parameters like progressiveness, average path velocity, straightness linear velocity (VSL), curvilinear velocity (VCL), straightness, linearity sperm head elongation ratio, area, linearity amplitude of lateral head department (ALH) and beat cross frequency (BCF) were found to be reduced in arsenic intoxicated rats. These results are not correlated with the histological studies. On oral admini-stration of selenium ameliorated the adverse effects of arsenic as compared to arsenic alone treated rats. Our findings clearly demonstrate that administration of selenium could prevent some of the deleterious effects of arsenic in the testis.

Today all nations in the world focus on remaining competitive advantage by adding high values to their fashion businesses. The most typical example of such added value is fashion collection. In case of London Fashion Week, which is among the world’s top 4 most famous fashion collections where more than 5,000 journalists and buyers from 25 nations can be expected every season, it has great contribution to the economic wealth of London. It induces consumption of 20 million GBP and economic production effects of one hundred million GBP. According to Joo (2009), one of the main purposes of fashion collections can be defined as the invigoration of international marketing and the creation of consumption demand. Fashion collections lead to increased direct sales and consumption demand by developing new products based on leading fashion trends that are presented in the collection. The so-called Big four collections in Paris, Milan, New York and London have their own Country of Origin (COO) image, which represents each country, cities, brands, products and services. For example, Paris collection has been established as luxury image with hand-made and Haute Couture. Not only fashion collection but also fashion brands have applied specific country characteristics to their fashion brand’s image. This serves as a critical factor of competitiveness that communicates an integrated image of brands to the customers. Also, within the purchase decision-making process, consumers consider COO as an important element. Therefore, organizer of fashion collections as well as brands that engage in such should consider COO as a key factor. Most of the previous studies about fashion collections focused on content analyses. For example, Joo (2009) compared characteristics and current situations between four major overseas cities’ collections and Seoul collection. Additionally, there are studies about fashion style, trend, design and textile. Characteristics of color change in 1990s fashion collection (Kim & Kim, 2007) and an analysis of design of hats and fashion images in collections (Jeong & Jeong, 2008) have been conducted as well. Previous studies related to COO mainly focused on the product (Bilkey & Nes, 1982) and how the image of the producing country affects product evaluation. Thus, the purposes of this study are 1) to examine of fashion collection’s COO and fashion brand image effects on brand evaluation and purchase intention, 2) to analyze differentiation factors of COO image, brand evaluation, purchasing intention on Seoul, New York and Paris collection. We surveyed Korean, American and French who have experience in their own country’s fashion collection and used SPSS 21 for data analysis. Fashion collection’s COO and brand image has a great effect on brand evaluation and purchase intention. Moreover, it seems to increase the purchase intention by affecting brand evaluation. Therefore, the results of the study are as follows. First, we can confirm that the better the fashion collection’s COO and fashion brand image, the higher brand evaluation and purchase intention is. Second, when assessing fashion collection’s COO image and fashion brand image, brand evaluation and purchase intention differ according to Korea, US and French national stereotypes. This study goes beyond the general product-centric COO studies and introduces the fashion collection’s COO that can be valuable research in terms of contribution not only to academia, but also to the industrial field.

Although the role of Guanxi in the Chinese business to business (B2B) market as a form of relationship marketing has received increasing attention in recent years, few empirical studies have explicitly distinguished between Guanxi and relationship marketing. Westerners typically consider Guanxi as unethical, but foreign-invested enterprises (FIEs) may have some difficulty in fully practicing relationship marketing in China without considering the influence of Chinese culture. In this regard, this study is guided by the following research question: “In China, should foreign-invested enterprises (FIEs) adopt Guanxi instead of relationship marketing in the B2B market?” In this study, we first provide an overview of previous research on Guanxi, focusing on the fundamental differences between Guanxi and relationship marketing. We then provide an empirical analysis of the differential effects of Guanxi and relationship marketing on firm performance by investigating 295 FIEs in the Chinese B2B market. The results suggest that Guanxi and relationship marketing are not trade-off options in today’s Chinese market. Guanxi and relationship marketing have synergetic effects on firm performance, that is, they have differential effects based on the mode of market entry and the type of competitor. Guanxi is more likely to influence firm performance for collaboration based entry firms rather than entry without collaboration firms, whereas relationship marketing is more likely to influence firm performance when FIEs’ main competitors are foreign firms than when they are local firms.

This study is to propose the paradox management process to analysis and solve the public education’s dilemma between the standardized education and the personalized education. The process is based on combining the TOC(Theory Of Constraints) and TRIZ(Russian Theory of Inventive Problem Solving), which is a creative way of thinking to draw the synergic effect by pursuing simultaneously the conflicting elements. Through this research, a new concept of learning method can be suggested on a public course.

Beta-catenin (CTNNB1, catenin (cadherin-associated protein), beta 1) is involved in various biological processes, including embryogenesis, tumorigenesis, angiogenesis and progression of metastasis. CTNNB1, as a multifunctional and oncogenic protein, has important roles in adhesion between Sertoli cells through an N-cadherin-dependent manner and in various cancer types through its over-activation. In addition, CTNNB1 can interact with estrogen/estrogen receptor alpha complex, which regulates the transcription of WNT (wingless-type MMTV integration site family)/CT-NNB1 target genes. Recently, we investigated the functional roles and expression pattern of CTNNB1 during the morphological changes of embryonic gonads of chickens and the estrogen-dependent regulation of CTNNB1 in oviduct development and potential functions as a biomarker of CTNNB1 in human epithelial ovarian cancer using the chicken as a biological research model. Therefore, in this review, we provide a new insight of potential role of CTNNB1 in the development of the female reproductive tract during early embryogenesis and ovarian carcinogenesis of laying hen models.

The majority of early embryonic mortality in pregnancy occurs during the peri-implantation stage, suggesting that this period is important for conceptus viability and the establishment of pregnancy. Successful establishment of preg-nancy in all mammalian species depends on the orchestrated molecular events that transpire at the conceptus- uterine interface during the peri-implantation period. This maternal-conceptus interaction is especially crucial in pigs because in them non-invasive epitheliochorial placentation occurs, in which the pre-implantation phase is prolonged. During the pre-implantation period, conceptus survival and the establishment of pregnancy are known to depend on the developing conceptus receiving an adequate supply of histotroph, which contains a wide range of nutrients and grow-th factors. Evidence links growth factors including epidermal growth factor (EGF), insulin-like growth factor-I (IGF-I), vascular endothelial growth factor (VEGF), and colony-stimulating factor 2 (CSF2) to embryogenesis or implantation in various mammalian species; however, in the case of pig, little is known about such functions of these growth factors, especially their regulatory mechanisms at the maternal-conceptus interface. Our research group has presented evidence for promising growth factors affecting cellular activities of primary porcine trophectoderm (pTr) cells, and we have identified potential intracellular signaling pathways responsible for the activities induced by these factors. Therefore, this review focuses on promising growth factors at the maternal-conceptus interface regulating the develop-ment of the porcine conceptus and playing pivotal roles in implantation events during early pregnancy in pigs.

Proteinaceous insecticidal proteins, Cry proteins, from Bacillus thuringiensis (Bt) are insecticidal proteins that are highly active against several species of Lepidoptera. Thus, cry genes encoding these Cry proteins have been widely applied for construction of transgenic crops resistant to pest insects. In this study, through the 3D structure prediction and accompanying mutagenesis study for the Mod-Cry1Ac, 7 and 16 amino acid residues from domain I and II, respectively, responsible for its insecticidal activity against larvae of Spodoptera exigua and Ostrinia furnacalis were identified. We used site-directed mutagenesis to improve the insecticidal activity of Mod-Cry1Ac, resulted 31 mutant cry genes. These mutant cry genes encodes potent insecticidal proteins in the form of crystalline protoxins of 95 kDa. SDS-PAGE analysis of the recombinant polyhedra revealed that expressed Cry proteins was occluded into polyhedra and activated stably to 65 kDa by trypsin. When the insecticidal activities of these mutant Cry proteins against to larvae of P. xylostella, S. exigua and O. furnacalis were assayed, they showed higher or similar insecticidal activity compared to those of Cry1Ac and Cry1C. Especially, Mutant-N16 is considered to have the potential for the efficacious biological insecticide since it showed the highest insecticidal activity.

An in vitro study was conducted to determine the effects of defaunation (removal of protozoa) and forage sources (rice straw, ryegrass and tall fescue) on ruminal fermentation characteristics, methane (CH4) production and degradation by rumen microbes. Sodium lauryl sulfate, as a defaunation reagent, was added into the mixed culture solution to remove ruminal protozoa at a concentration of 0.375 mg/ml. Pure cellulose (0.64 g, Sigma, C8002) and three forage sources were incubated in the bottle of culture solution of mixed rumen microbes (faunation) or defaunation for up to 24 h. The concentration of ammonia-N was high under condition of defaunation compared to that from faunation in all incubations (p<0.001). Total VFA concentration was increased at 3, 6 and 12 h (p<0.05~p<0.01) but was decreased at 24 h incubation (p<0.001) under condition of defaunation. Defaunation decreased acetate (p<0.001) and butyrate (p<0.001) proportions at 6, 12 and 24 h incubation times, but increased propionate (p<0.001) proportion at all incubation times for forages. Effective degradability of dry matter was decreased by defaunation (p<0.001). Defaunation not only decreased total gas (p<0.001) and CO2 (p<0.01~0.001) production at 12 and 24 h incubations, but reduced CH4 production (p<0.001) at all incubation times for all forages. The CH4 production, regardless of defaunation, in order of forage sources were rice straw > tall fescue > ryegrass > cellulose (p<0.001) up to 24 h incubation.

The effects of environmental and nutritional requirement such as temperature, pH, different media, carbon, nitrogen, and carbon-to-nitrogen ratio on the mycelial growth of Cordyceps militaris strain ‘Yedang 3’ were studied. The optimum temperature and pH for the growth of mycelium were 20-25oC and pH 6-7, respectively. Out of ten media tested, mushroom complete media (MCM) was the best medium for fast mycelial growth, and Sabouraud’s dextrose agar yeast extract (SDAY), malt extract yeast extract agar (YMA) also were favored. The color and shape of colonies varied in different media. The best carbon sources for mycelial growth were fructose, mannitol, and sucrose, whereas the best nitrogen sources were tryptone and peptone. However, mycelia grew slowly in inorganic nitrogen compounds such as NH4Cl, (NH4)2SO4, NH4NO3, and NaNO3. The optimum C:N ratio observed on the culture media was 30-40 range. These results provided basic information on cultural characteristics of vegetative growth and might be useful for spawn production in Cordyceps militaris.

The purpose of this study is observing the process of learning Chinese character of preschool children and clarifying their language ability and the level and range of vocabulary. This paper sees the process of Korean children acquiring vocabulary in two ways: The first one is researching the vocabularies used in children's stories that preschool children often read or hear. The other one is researching the vocabularies that children hear or speak in the conversation with surroundings. To this end, two methodologies have been adopted: literature analysis and observation analysis. Literature analysis is investigating the fairy tales that children likes and analyzing the Chinese characters and vocabularies used. Observation analysis is recording the conversations between a child and his surroundings, and then transcribing and analyzing it. Almost every child reads fairy tales that helps to the formation of children's language ability. Therefore, the language of children's stories is the expectancy which Korean society expects children to understand the accomplished living environment and culture to. Therefore, children contact the basic cultural vocabulary in Korean society, contacting fairy tales. Children develop their intelligence and language through engaging in the daily conversations with their parents and acquaintances. Although they are influenced by communications with their peers of the same age group, the contents and range of the language used in the context of their surroundings affect a lot more. Thus, the process of children's language acquisition is developed through the conversations with parents and acquaintances. It is very possible that the language ability of a child in a family is transferred by parents rather than the intelligence and the ability of the child. Consequently, studying children’s Chinese character vocabulary through the two processes, you can see how level of the Chinese character vocabulary that children contact and use is, what characteristics it has and how much the range of use is.
