The crop rotation of rice and ginseng in paddy field has very important meaning because up-land field suitable for ginseng cultivation is now being insufficient day by day in main ginseng production area. This studies were conducted to define basic problems related to ginseng cultivation and replanting in paddy field. In Keumsan district, the most serious problem on ginseng cultivation in paddy field was excess of mineral salts left behind in the soil of rice cultivation. The amounts of organic matters, CEC and the mineral elements including potassium were higher in the soil of paddy ginseng field compared to those of upland. Plant growth of 3 and 4 year old ginseng and root yield of four year old ginseng cultivated in paddy field of 1st and replanting were not decreased compared to those of 1st - planting of up-land field, but those were significantly decreased in replanted compared to those of first planted upland field. Crop rotation with ginseng and rice in paddy field seemed to be a good way to avoid hazards of continuous cropping of ginseng with it's outyield of root and less infection of diseases. Amounts of crude saponin and ginsenosides of ginseng cultivated in paddy field were not differ from those of upland field.

Purpose - Increasing sales of PB rice products can hinder the growth of domestic brands of rice, notwithstanding that the government is promoting domestic brands of rice. This analysis evaluated the influencing relationship among the variables of PB image, product credibility, and purchase intention of consumers who have never bought PB rice, to know the factors influencing consumers' decisions to purchase PB products. Research design, data, and methodology - PB products' brand image was analyzed as the factor that has a direct effect on purchase intention. The mediation effect of credibility on PB products is also analyzed, in terms of influencing the relationship between PB products' brand image and purchase intention. The analysis is performed on consumers that have not purchased a PB product and consumers who have purchased PB products from major distributors. Data is collected through questionnaires, from 389 of responders, and the AMOS 19.0 statistics package is used as a statistical tool. Results - It is proven that brand image has direct effects on the credibility of the product, and the credibility of product has a direct effect on purchase intention. However, it is revealed that brand image does not directly affect purchase intention, but that brand image indirectly affects it through the credibility of the product. Although the customers' recognition about PB image is low, the result shows that PB products' external attributes have effects on customers' purchase intention relating to the PB product. Therefore, it is important to establish the credibility of the PB product more than other products in terms of marketing. Conclusions - The following are the implications of the study. First, in a rice brand promotion, the credibility of the product should be ensured by a uniform brand image. To ensure the credibility of a product, the RPC brand and other brands should be unified, and the unified brand image should be applied to every product. Second, the package must possess a design as well as contents that could build consumers' perception of product credibility. Products' external attributes contribute to their credibility, which leads the consumers to purchase the products, including those consumers who have never bought PB rice products. Therefore, the products' credibility and sales can be reinforced by applying information about consumers' considerations when buying the PB rice product in different colors, font sizes, and packaging designs. This study is meaningful in two ways. First, it seeks to identify an NB revitalization strategy by exploring the purchasing behavior of customers who have no experience in buying PB rice products. Second, the results of previous studies about general brands are considered and applied in this study in order to investigate the influencing relationship among different factors of PB products. However, this study is a consumer awareness investigation; therefore, its results only have limited meaning to the relationship between brand image and purchase intention.

Considering the advent of the Fourth Industrial Revolution, this study examines the changes and influences of intelligent information technology and the role of consumer education in the context of consumption life. The purpose of this study is to provide a theoretical foundation to effectively respond to the future consumption society as an independent consumer by enhancing the understanding of the Fourth Industrial Revolution in terms of consumption life. First, in terms of changes in the consumption paradigm in the Fourth Industrial Revolution, production and consumption are converged by being shared through a comprehensive connection platform in real time. Regarding the meaning of consumption, mental experience is being emphasized; moreover, usage and sharing, rather than ownership, are being highlighted. In terms of major changes in consumption life, the emergence of a more convenient smart consumption life and the possibility of personalized consumption optimized for individual demand are anticipated. Moreover, sustainable eco-friendly consumption is expected to increase further, and rapidly changing consumption trends will experience accelerated progress in consumer-centered changes. Next, the predicted problems in consumption life in the Fourth Industrial Revolution include unequal consumption due to intelligent information technology power center and the use and management of personal information data. Furthermore, ethical concerns related to the introduction of new technologies will become prominent, eventually resulting in issues concerning consumption satisfaction. To effectively respond to these new paradigm changes, consumer education should be value-centered. Ethical aspects of consumption should be considered, and consumption life should include trust and mutual cooperation. Furthermore, consumer education should facilitate creative convergence.

This paper considers how Koreans found their positions in the complex, overlapping, disjunctive, and interconnected "Oriental" repertoires in the early Cold War years. When we use the term, Oriental, it should require careful translation from context to context because it may be subject to very different sets of contextual circumstances. Klein views Cold War Orientalism in the complex of various regions including East Asian and Southeast Asian countries; however, when Koreans are contextualized at the center of the discussion the Orientalism produces another discursive meaning. Even though many great researches have been done on Korean immigrations, Korean American literatures, and US-Korea economic, political, and foreign relations, not many discussions about Korean American popular cultures have been discussed in the basis of the Oriental discourse in the United States.For this argument, this paper investigates the performative trajectory of a girl group "Kim Sisters" who began to sing at the US military show stages in South Korea in 1952 during the Korean War. They moved to Las Vegas show stages in 1959 and later appeared in Ed Sullivan Show more than thirty times during the 1960s and 70s. Meanwhile, they not only returned to South Korea often times to perform at the stages for Korean audiences in South Korea but also played at the shows for Korean immigrants in the United States. Korean American immigration to the United States has followed a different route from the majority of Asian American population such as Chinese or Japanese Americans, which means that efforts to compare this particular group to the others may be unnecessary. Rather doing comparative studies, this paper, therefore, focuses on the formation of the intersecting and multiple identities of Korean female entertainers who were forced or forced themselves to be incorporated into the American popular "Oriental" imagination, which I would call "embedded" identities. This embeddedness has been continuously maintained in the configuration of Korean characters in the United States. This will help not only to observe the discursive aspect of Asian American identity politics but also to claim a space for comparatively invisible Korean characters in the United States which has been often times neglected and not brought into a major Asian American or Oriental historical discourse. This paper starts with American scenes at the beginning of the twentieth century to trace Americans Oriental imagination which was observable in the various American cultural landscape and popular music soundscape. It will help us more clearly understand the production and consumption of the Korean "Oriental" performances during the early Cold War period and especially the Korean performance in the American venue, silently overshadowed into the political, social, and cultural framework.

This paper examines how 'house' is meaningful in Chi Li's novel. Chi Li focuses on the house as a symbol of status, and the house as a place of gender performance. First, as a sign that symbolizes an individual's identity, 'house' is divided into intellectual and petit bourgeois, and constitutes binarism into civilization/non-civilization, knowledge/non-knowledge, spirit/anti-spirit and superior/inferior. In recognizing the irrationality and unfairness behind house symbolizing intellectual and petit bourgeois, Chi Li shatters the boundaries of the binaralized house as a sign of identity. Second, it dismantles the house as a place where gender is (re)produced. This is accomplished through two aspects. One is to re-define a private area house as a public area in which economic activity occurs. The house, as a public area in which economic activity occurs, becomes a place where women are reborn as economic entities. Passive, dependent femininity is reconstructed as independent and subjective. The other dismantles the definition of the house which is identified with masculinity. The house identified with masculinity is a place that symbolizes the socio-economic capacity of men. According to the socio-economic ability of males, the house is a place symbolizing the realization of masculinity, and it becomes a place to fix the gender order while reproducing masculinity. It may become a place to experience the weakening or defamation of masculinity. At that moment, the house becomes a place where the gender order of masculinity and femininity is overturned. Through this, Chi Li reconstructed, and in a sense revolutionized the definition of the house as a place where traditional gender is (re) produced by dismantling the definition of fixed femininity or masculinity.

The purpose of this study was to explore the characteristics of defining concrete and abstract nouns for the elderly. A total of 382 elderly participated in this study and they were classified into four age groups (i.e., over 55 to under 64, over 65 to under 74, over 75 to under 84, and over 85 year-old group). They performed the word definition task, composed of five concrete and five abstract nouns. The total scores and numbers and ratio of core/supplementary meanings were compared among four elderly groups. The frequency and ratio of error types were also examined. The results showed that all four groups had statistically significant differences in total scores, numbers and ratio of core and supplementary meaning of concrete noun definition task. In addition, abstract noun definition performances revealed group differences except the two groups (over 75 to under 84 and over 85-year-old group). The oldest group showed a sharp increase in error production. The highest ratio of error types were personal experience in over 55 to under 64-year-old group, and over 65 to under 74 year-old groups; and for the target word repetition in over 75 to under 84 year-old group; and no response in over 85 year-old group. In conclusion, both concrete and abstract word defining abilities had age-related deterioration. This decline results from impairment in spreading semantic knowledge within semantic network, which is vulnerable to aging. Characteristics of word definition for elderly can provide basic information to understand various neurolinguistic disorders associated with age.

In school facilities, space is the basic framework. The structure and arrangement of space will provide the form and feel of school facilities. In order to become a high-quality school facility, it is necessary to focus on the educational, human and ecological aspects of the instructor and learner until the space is conceived, designed and completed. However, even when public education was introduced in the past, it did not become a school space considering this aspect. The school space, which focuses on efficiency and labor production, is a school space that reflects the characteristics of a factory-type school, which has been occupied by a large number until recently. Although efforts to improve the quality of school facilities have been attempted in recent years, there is also a need to pursue more active changes. Future-oriented and progressive school spaces include flexibility, connectivity, individualization, diversity(creativity). In other words, space should be flexible so that it can be used faithfully according to the educational situation, not the fixed and limited school space as in the past. In the future, the school space should be open and securely linked to the place where it is essential to complete community relations with the community. In addition, space should be flexible so that the school can meet the needs of each student as much as possible. And the school space should be transformed from the space design of the past fixed pattern to reflect the close relationship between spatial, psychological, physiological, and behavioral areas. When school space needs to shift away from the past and change in a new future-oriented direction, the remaining tasks should be presented with specific characteristics and content of the direction. And the function of the consignment should be handled by related research. Although the text of this study reveals the characteristics of future-oriented school space, more concrete and empirical research results should be presented by subsequent research at home and abroad. It is necessary to reduce trial and error in creating a future-oriented school space where both professors and learners can be satisfied by analyzing the common points and differences between the results of the study. In order to do this, it is necessary to make efforts to approach such research based on the participation of the subjects who teach and learn directly at the school site.

In this study, we have developed 3D8 scFv transgenic pig (TG) by microinjection of fertilized one-cell pig zygotes (2.17%). The effect of 3D8 scFv TG on porcine reproductive and respiratory syndrome virus (PRRSV) resistance were evaluated through PRRSV VR2332 (1×103 TCID50/mL) challenge and transmission experiments. As a result, the average daily weight gain (ADWG) of TG increased compared to the wild type pigs (WT) in PRRSV challenge groups and the serum viremia levels of the TG was significantly lower than of WT on the 7 day and 21 day after infection, meaning that the viral shedding was suppressed by 3D8 scFv expression. These results suggest that the expression of 3D8 scFv in pig could suppress spreading of infected virus to pigs sharing a room.

With the advent of the fourth industrial revolution, the interest in the internet of things (IoT) in manufacturing is growing, even at foundries. There are several types of process data that can be automatically collected at a foundry, but considerable amounts of process data are still managed based on handwriting for reasons such as the limited functions of outdated production facilities and process design based on operator know-how. In particular, despite recognizing the importance of converting process data into big data, many companies have difficulty adopting these steps willingly due to the burden of system construction costs. In this study, the field applicability of IoT-based devices was examined by manufacturing devices and applying them directly to the site of a centrifugal foundry. For the centrifugal casting process, the temperature and humidity of the working site, the molten metal temperature, and mold rotation speed were selected as process parameters to be collected. The sensors were selected in consideration of the detailed product specifications and cost required for each process parameter, and the circuit was configured using a NodeMCU board capable of wireless communication for IoT-based devices. After designing the circuit, PCB boards were prepared for each parameter, and each device was installed on site considering the working environment. After the on-site installation process, it was confirmed that the level of satisfaction with the safety of the workers and the efficiency of process management increased. Also, it is expected that it will be possible to link process data and quality data in the future, if process parameters are continuously collected. The IoT-based device designed in this study has adequate reliability at a low cast, meaning that the application of this technique can be considered as a cornerstone of data collecting at foundries.

Metaverse combines the real and virtual worlds to create a world where all experiences and activities in the real world are possible even in the virtual world without time and space constraints. Currently, metaverse technology is expanding and converging into the realms of society, economy, and culture. In particular, the MZ generation, the main user base, is engaged in various cultural activities such as games, contents, culture, exhibitions, and performances in the metaverse world. Archives, one of the cultural institutions, should provide a new type of service by fusion of Archival information services with metaverse technology so that the MZ generation can know the value and meaning of archives. This will arouse the interest of the MZ generation, which will naturally increase the awareness of the archives, increase visits and use, and will serve as an opportunity to expand the user base. Therefore, in this study, the concept, type, and characteristics of each service were examined, and the representative metaverse platform for each service was selected and a platform utilization plan suitable for Archival information services such as exhibition, experience, and publicity was proposed. In addition, by using 'Spatial', a blockchain-based social metaverse platform, to directly produce exhibition contents, we want to check the considerations suggested, the production process, and the advantages of the metaverse exhibition.
