  • Shoot tips of grape were cultured in uitro and tried to identify optimal culture conditions for regeneration, multiple shoot formation from meristemoid tissue and those subsequent elongation of multi-shoots. Healthy growing shoots were taken in early May, rinsed with running tap water, soaked in a neutral detergent and washed with soft brushing, and washed out with tap water, then sterilized with 10g Ca(ClO)$_2$/140 mL distilled water (Wilson's solution) for 5 min. Survival percentage of the cultures which were sterilized as above procedures was highly increased, compared with the other sterilized method. Propagation of multi-shoots from meristemoid showed a good response in 3/4 strength MS medium enriched with 0.1 mg/L NAA and 3.0 mg/L BA. Shoot elongation from multi-shooting clump well occurred in 3/4 strength MS medium supplemented with 80 mg/L adenine sulfate, 0.1 mg/L NAA and 1.0~2.0 mg/L BA.

  • Air-containing fashion, which can offer diverse functions through the inflow and outflow of air, is highly relevant in today's mobile society, where people are experiencing a wider range of environments. This study attempts to suggest the possibility of air-containing multi-functional fashion that could continuously be utilized by developing a design for an air-containing jacket using modular systems. In this research, the modular systems in architecture and furniture design were referenced through a review of the literature for the purpose of establishing modular systems in fashion. Functions relevant to the mobility of today's society are derived from the results of advanced research and applied to the design of modules of the jacket. The modules are integrated through the modular systems. The folding and unfolding structure in architecture and furniture is applied as a folding system in fashion, the vertical accumulation structure as a layering system, and the horizontal integration structure as a combining system, and in addition, the containing system has emerged in fashion. Each module is designed to fulfill certain functions, such as cushioning, heat insulation, and portability. The folding system is utilized in designing the cushion module to support the neck and back of a wearer by making its hood and hem fold in the back. The application of a layering system was suggested by making the vest, combined with the neck cushion and back cushion via the combining system, layered with its insulation module. By applying the combining system, the hood that includes the neck cushion, the skirt that includes the back cushion, the body that includes the insulation module, and the sleeves can be connected and separated by a zipper. The applicability of this concept was proven by applying a developed design to an actual item.

  • The Korean clothing culture has shown rapid changes along with influences of western cultures, with social changes due to the liberation from Japan, the Korean War, and the economic growth concentrated on export since the westernization of Korea had begun. Also clothing materials, as a phase of such culture, have been changed. Among silk fabrics, "Dan (단: damask of satin texture with Korean traditional patterns are inwoven)", which has been concerned one of the most beautiful and precious fabrics due to its complexity and difficulty of processing. Since the beginning of the Era of Enlightenment(Kae-hwa-gi), Dan fabric materials and weaving methods have changed. It seems that the figured texture using the Jacquard loom began in 1936. when the Jacquard machine began to be imported from Japan into Korea. From that time on, new fabric materials, such as yangdan (양단), and popdan (법단), hobakdan (호박단), silk and rayon mixed Dan(교직양단) began to be produced. Before 1950's there were some restrictions about the Number of wefts, so the production of the one colored dan(단색단) was more common than that of the multi colored dan(다색단). But with the spread of 4$\times$4 shuttle box loom (양사정직기), various kinds of the multi colored dan have been produced after 1960's. Around the end of 1980's, automatic shuttle change loom have been generalized and 7 color dan(칠색단), 9 color gumsadan (구색금사단) have been current in multi colored dan. In terms of materials, synthetic and chemical textiles had been used widely and alter 1980's most fabrics, of which the ground weave is not being woven with satin-weave but being woven with plain or twill-weave, are named Dan in general.

  • This study aims to develop a multi-functional cage for dogs as a house to reduce their anxiety when they go out using cages. This study investigates the types and characteristics of cages and cage preference by surveying men and women in their 20s who use them. The cage product reviews are also analyzed. The research results are as follows: First, domestic dog cages are classified into crate, shoulder, cross (sling bag), backpack, carrier, and stroller types. The crate type is easy to clean and can be used as a house, but it is bulky and therefore inconvenient to carry when using public transportation. The shoulder type is a fabric material with good air permeability but has the disadvantage of being easily soiled. It can be used as a house and is light weight, making it convenient when using public transportation. Second, as a result of consumer research, respondents prefer the shoulder-type fabric over the crate-type plastic material. Third, from the shoulder-type product review, the shape stability, companion dogs' psychological safety, the wearability of companions, and management convenience are derived. Fourth, based on the survey results, a multi-functional cage is developed taking into account the companion dog, companion person, and functional factors.

  • The purpose of this study is to examine how the control of an agent according to a driver's social status affects user experience factors in a multi-user environment of self-driving vehicles. We conducted a user study where participants viewed four scenarios (route changing/parking x accepting/declining a fellow passenger's command) and answered a survey, followed by a post-hoc interview. Results showed that either the routing scenario or accepting a passenger's command scenario had higher usefulness (convenience, effectiveness, efficiency) than their counterparts. Regardless of the car owner's social status, participants rated AI agents more positively when they met their goals effectively. They also stressed that vehicle owners should always be in control of their agents. This study can provide guidelines for designing future autonomous driving scenarios where an agent interacts with a driver, and passengers.

  • Deep Learning is a useful method for classifying and recognizing complex data such as images and text, and the accuracy of the deep learning method is the basis for making artificial intelligence-based services on the Internet useful. However, the vast amount of user da vita used for training in deep learning has led to privacy violation problems, and it is worried that companies that have collected personal and sensitive data of users, such as photographs and voices, own the data indefinitely. Users cannot delete their data and cannot limit the purpose of use. For example, data owners such as medical institutions that want to apply deep learning technology to patients' medical records cannot share patient data because of privacy and confidentiality issues, making it difficult to benefit from deep learning technology. In this paper, we have designed a privacy preservation technique-applied deep learning technique that allows multiple workers to use a neural network model jointly, without sharing input datasets, in multi-party system. We proposed a method that can selectively share small subsets using an optimization algorithm based on modified stochastic gradient descent, confirming that it could facilitate training with increased learning accuracy while protecting private information.

  • Advertising is regarded as one of media's most proficient instruments of reflecting changing society. It represents the channel through which globalization and consumption culture have spread into everyday life. This study explores the significance and representations of multi-culturalism in contemporary television commercials. For the purpose, the social and historical meanings of the term 'multi-culturalism', generated inside and outside Korea, are discussed. A series of text analysis are followed, focusing on the representation of non-Korean models in terms of ethnicity and race. The result shows that the advertising is the instrument utilized in creating the relationship between multi-culturalism and racialism, which is called 'strategic multi-culturalism'. This strategy commonly happens in today's commercial advertising such as information/telecommunication, real estate/branded apartment complex, and bank/finance market. Despite the increasing number of multi-cultural commercials in the past decade, multi-culturalism in Korean society has not yet fully articulated.

  • This study investigates the potential for multi-cultural youths, given their innate bilingual and dual culture, to be trained as the competent ODA professionals. For the purpose of collecting information, we organized two different kinds of FGI in 2015. The first FGI was conducted with a group of 10 expert participants from August 17 to September 25. The second FGI was conducted four times, from October 5 to October 23, with 13 adolescents from multi-cultural families from Russia, Mongolia, Vietnam, India, Indonesia, Japan, and China. The semi-structured interview items were passed through a formal review process of the Institutional Ethics Committee. Furthermore, with the participants' pre-consent to recording, all recorded data were categorized through the transcription process. The results are as follows. While the potential for nourishing bilingual and dual cultural capabilities are high for the adolescent children of multi-cultural families, the expert group also emphasized the negative aspects of these capabilities being suppressed due to the relatively oppressed family environment. The expert group therefore suggests the following: building parent awareness of ODA human resources, developing an educational career transition roadmap, and providing institutional incentives for ODA. In addition, to some extent, the researchers were able to detect some positive self-esteem among the adolescent children of multi-cultural families as a result of the bilingual and dual cultural competencies required to be ODA personnel. In sum, the research provides insight into the need for national social support for the adolescent children of multi-cultural families, so that their strengths are not extinguished, in order that they might grow up as competent ODA personnel.

  • According to the increasing education concerns for students of multi-cultural family, it has been focused about the multi-cultural education's Model and the study of teaching way, something like that. However, the study of computer education is very rare and not continued. But Multi-culture students' information gap is remarkably high as compared with common students. So, the measures for reducing the information gap is needed for their future study and future life. Therefore, this thesis will be suggested computer education as an additional education process for the students of multi-cultural family to be easily accustomed to Korean education currents and reduce the information gap for students of multi-cultural family. To verify the validity, I will conduct the survey for multi-cultural experts. After that, the quality of education in stages will be constructed.
