The Korean society was forcefully merged with the invasion of Japan in 20th century, and traditional culture of Korea was damaged severely by colonization from Japan. After liberation, Korean society experienced drastic social change with Korean War, and industrial economy and democratic system developed as modernization and democratization occurred. However, Korean traditional culture dissolved more severely as Korean society developed industrial economy and democracy. As criticism of existing Western center of society and the emphasis of cultural identity of non-western regions and third-world, world society preferred exchange of culture of diverse nations and people with each other in advent of postmodernism thoughts in mid-late 20th century. If the cultural identity of Korea was dissolving meanwhile, it was needed to be recovered again. Despite the research in Korean history, language, art, architecture was performed to recover cultural identity of Korea, it did not go in-depth with Korean mythology, for Korean mythology is considered as superstition or savage. Mythology shows subconscious group psychology of people who live in certain specific region. Studying Korean mythology is one of the ways to rediscover cultural identity of Korea. In order for Korean mythology to be known to many people, its stories should be told by media. There were movies, plays, drama, and novels produced based on existing Korean mythology as introduction, then these mythical stories are appear in subculture contents such as recent comics, animation, webtoon, games, and light novels. Then population of game players and webtoon readers increased as dissemination of PC and smart phones, and increasing market scale of subculture contents increased a population of consumers of comics, animation, and light novel. Consumers of sub-culture contents were interested as many of these contents were created, base on Korean mythology. Therefore, this paper is written as research on Korean mythology and its signification in sub-cultural contents which were produced base on Korean mythology.

Today, in Korean modern fine arts, 'cartoon images' are utilized for their roles of the 'personas' of the artists, and as the 'texts' for the artistic discourses, while they play a role as a bridgehead between the public and art. In this study, we made a study, focusing on 'Atomouse' of Lee Dong-gi, in order to examine how the borrowing of the 'cartoon images' was made in the Korean modern fine arts, and what its period context is. 'Atomouse' of Lee Dong-gi is the first cartoon character that appeared in Korean modern fine arts, and it has acquired a symbolism of a subculture being acknowledged as art. In this study, we tried to find out what period contexts the changes of 'Atomouse' have, focusing on the private exhibitions of Lee Dong-gi, such as 'Smoking' Exhibition (2006), 'Bubble' Exhibition (2008), 'Double Vision' Exhibition (2008), 'The Garden of Uncertainty' Exhibition (2012) and 'Do Not Look Back with Angry Face' Exhibition (2013). Atomouse was born in the era of 'lack of pop' a change was attempted of it in the era of 'excess of pop' and its proceeding ended along with the 'settlement of the neo-pop'. From Atomouse started from the unconsciousness of the artist, we can find the 'identity' of the Republic of Korea, which was being influenced by the 'American and Japanese' culture, as well as the symbolism of a subculture being acknowledged as art, while it emerged as an icon to represent the Korean pop art of the time. Then, as the agony and self-examination of the artist was contained in it, its use was changed into the role as a persona and it was utilized as a tool to connect the and figurative worlds. In the end, the artist put an end to the proceeding of the 'Atomouse' at the boundaries of a persona and an alter ego, removing the creation with his own hands. In the process in which Lee Dong-gi created and changed 'Atomouse', the start-up and growth of the pop art are included in the history of the Korean modern fine arts, apart from a study of an artist. 'Atomouse' was not only painted on the walls of the subway stations in the form of public art, but it tried to closely communicate with the public through the collaboration with diverse media. It made the best use of the 'marketability' which a 'cartoon character' had at first, so that pure art was made a step closer to the public. So 'Atomouse' of Lee Dong-gi not only raised a subculture into the realm of high art, but lowered the door sill to high art. Through the study we could confirm what position 'Atomouse' of Lee Dong-gi, which started absurdly between parody and Hommage, takes in Korean modern art of today.

Long-term subcultured rose embryogenic calluses, which had been maintained for more than 5 to 6 years since the first embryogenesis from calluses induced from in vitro roots of rose, were identified as potential material for the development of transgenic plants. The first embryogenic calluses from 'Sweet Yellow' and two breeding lines (KR056002 and KR056006) were obtained in 2007 and 2009, respectively. Subsequently, we found that plants regenerated from long-term embryogenic calluses (LEC). Whereas the LEC from 'Sweet Yellow' takes 3 to 4 months to regenerate plants, those of the two breeding lines take 4 to 5 months. This period of time is the same as that taken for plants to regenerate from the first embryogenic callus. New embryogenesis was observed from atypical bodies (ABs) that appeared during the process of long-term subculture. We found that it is possible to use the AB as a material for new embryogenesis.

The purposes of this study were firstly to identify the microbial species on gutta-percha (GP) cones exposed at outpatient clinics using polymerase chain reaction, and secondly to evaluate the rapid sterilization effect of two chemical disinfectants at chair side. It also evaluated the alteration of surface texture of GP cones after 5-min soaking into two chemical disinfectants. A total of 100 GP cones from two endodontic departments were randomly selected for microbial detection using PCR assay with universal primer. After inoculation on the sterilized GP cones with the same microorganism identified by PCR assay, they were soaked in two chemical disinfectants: 5% NaOCl and 2% chlorhexidine for 1, 3, 5, and 10 minutes. The sterilization effect was evaluated by turbidity and subculture. The change of surface textures using a scanning electron microscope was also examined after 5 min-soaking in two chemical disinfectants. Results showed that four bacterial species were detected in 17 GP cones, and all the species belonged to the genus Staphylococcus. Two chemical disinfectants were effective in sterilization with just 1 minute soaking. On the SEM picture of NaOCl-soaked GP cone, a cluster of cuboidal crystals was seen on the cone surface. Present data demonstrate that two chemical disinfectants are useful for rapid sterilization of GP cone just before obturation at chair side, while CHX-soaked GP cone has cleaner surface without crystal precipitation than that of NaOCl-treated cone.

People are most commonly divided by their nationality, but that does not mean they share the same culture. Even for people from one cultural background, subcultures play an important role for diversity and identity, and popular music is one way to express them. This study analyzed 6 songs of the Hip Hop genre from the US, Germany and South Korea, with one song each from the time of first emergence of the term 'Hip Hop' and one song each from 2016, selected on the basis of popularity indicated by music record sales and specialist literature on the history of Hip Hop. Through semiotic analysis of early and recent Hip Hop in each country, the changes in popular Hip Hop over time were examined. The results of this study show that through standardization, Hip Hop in the three countries has superficially become more similar and more focused on the individual, but on a detailed level shows significant differences: while U.S. Hip Hop refers to the American Dream, German Hip Hop displays an extreme image of masculinity, and Korean Hip Hop deals with private thoughts. Although popular Hip Hop nowadays does not explicitly exercise social criticism it is still ascribed the symbolic significance of a rebellious and revolutionary cultural practice that can be used to criticize and change culture as well as society.

The genetic variations and the rate of mycelial growth in the dikaryon and the monokaryon stages of Pleurotus spp. were surveyed during their subcultures. The highest growth rate was observed on both the 3rd and the 4th subcultures. The remarkably rapid growth rate was detected in P. ostreatus dikaryon. Genetic similarities in the dikaryon and the monokaryon of P. ostreatus were more than 57.5% and 85.7%, respectively, and those of P. eryngii were more than 85.2% and 84.8%, respectively. The genetic similarities of monokaryotic P. ostreatus were higher than those of dikaryotic. The topology of phylogenetic trees showed that the divergence and the clustering patterns of branch did not correlated with the number of subcultures. This suggests that genetic variations occur very randomly on mycelial cultures. These results suggest that the monokaryotic mycelia is genetically more stable than the dikaryotic in subcultures, and that it is very useful to stock monokaryotic mycelia for making spawns and breeding of Pleurotus spp.

As a result of advenced research, Penicillium growth inhibition effect in media of cauliflower mushroom by different LED lighting color inhibited all treated groups, but blue wavelength treatment group was unfitted for culture of cauliflower mushroom due to lots of spore of penicillium. So, to investigated characteristics of mycelial growth of cauliflower mushroom according to different LED wavelength and LED wavelength color. As a results, all red wavelength treatment groups found highest mycelial growth tendency. Thus, mycelial growth investigated different quantity of red lighting wavelength conditions. The quantity of lighting wavelength was low intention, 1.41 ${\mu}mol/m^2S$ treatment group found highest mycelial growth. Effects of mycelial growth by subculture found difference of statistical in one time to carry out a subculture treatment group. Mycelial growth by different quantity of LED lighting in different media composition of wood chip media indicated highest trend in the Korean pine treatment groups. To cultured treatment group for 84th days found difference of statistical, when a quantity of LED lighting red wavelength 2.11 ${\mu}mol/m^2S$ treated in wood chip of the Korean pine media. In conclusion, good culture condition of cauliflower mushroom estimated quantity of red lighting wavelength 2.11 ${\mu}mol/m^2S$ in wood chip media of the Korean pine for 84th days.

Nursing organization culture is common patterns of believing, thinking and behaving resulted from a variety of experiences and interaction nurses in the same setting. This study was performed based on the assumption of existence of different subcultures within meta-culture, to identify the differences of subculture among 5 nursing units and to analyze the relationship between nursing organization culture and organizational commitment In this study, two kinds of instruments were used. One was the instrument of nursing organization culture developed by researcher through literature review and interview with nurses. The other one was Mowday's Organizational Commitment Questionnaire to measure organizational commitment of nurses. Both of them were structured with 5 scale. The answers were analyzed using SPSS program. The results were as follows : The meta-culture of the nursing organization culture was the people stable culture. There were significant differences in people development culture and people stable culture among 5 nursing units and all 5 units had different culture score. Especially, emergency room had strong development culture, and stable culture was dominant in operating room. Other units except emergency room and operating room had high scores in people stable culture than other culture types, but revealed different distribution. There were significant differences of the nursing organizational culture types -people development, task development, people stable, task stable-among 5 units. Four types of nursing organizational culture consisted of competing values in one organization. Nurses's organizational commitments were sign ificantly different among the units. The score per ceived by nurses who work in emergency room, operating room and leu was higher commitment score than that of medical/surgical nursing units Nurse's commitment to nursing organization was also related to total work period as nurse in any setting and work period in this hospital. Organizational commitment was significantly different among the nursing culture types, indicating that the scores of developmental culture were higher than stable culture. In conclusion, there were many different subcultures in nursing organization. In subculture, the organizational commitment was different. Therefore, the change of nursing organization culture or nursing unit culture needs to be considered to hire, give orientation, teach. and reallocate nurses efficiently. Research on nursing organization culture using both qualitative and quantitative method needs to be further considered. Furthermore, the strategy in nursing organization culture for nursing administrator to manage human resources efficiently and to change nursing unit effectively, needs to be developed.

The lack of characteristical understanding of the Home Economics Education will have difficulty in achieving the goal of the Home Economics Education. To allow the Home Economics Education class in school contribute toward the enhancement of the quality of life, it is inevitable to reinforce the recognition of the importance and necessity of the Home Economics Education and to newly propose a directional guidance forward the coming 21st century. The purpose of this study was to provide basic data for planners of the future Home Economics Education by surveying research administrators in charge of programming the overall school curriculum. This study was conducted under the following procedure to have the outcome as follows ; 1. Answers from respondents of age over 50 or careers over 16 years tended to grasp the goal of Home Economics Education in relation to the enhancement of quality of life rather than to the accumulation of knowledge, skill or capacity. 2. Of all the surveyed, 9.64% regarded Home Economics Education as an essential part of school education and the positive ratio was higher with younger respondents. 3. To the question asking if the high school Home Economics Education could have influence on one's capacity, 97.2% of the answerers said yes. The respondents with career under 15 year showed 100% of positive agreement in this matter and of age under 40 marked much higher ratio of 98.84% than the elders. 4. The overall recognition of the necessity for separate sections in Home Economics Education programmed in accordance with the 6th Revision of High School Curriculum displayed a considerably high ratio, with a little differences among age and job groups. The purpose of this study is to analyze and understand adolescents'culture, thereby to provide fundamental information for Preventive Education for Adolescents'Problems in Home Economic Education. 745 articles collected in computer communication service were used for the analysis. The data were analyzed by frequency and percentage using the SPSS/PC+computer program. The most important results of this study were as follows ; 1) Concerning 'Adolescent's Problems's, problems such as violence, homicide and robbery were treated with the greatest frequency. It was also analyzed that the older generations are highly inclined to understand adolescents'culture as a negative one, for example, 'delinquency'or 'immaturity'. 2) Although the area of 'Adolescents'Education'was treated most frequently reflecting the high educational concern in our society, the significant part of those articles were on wrongful educational administration. As much as 70.6% of the articles analyzed were on 'Education'and 'Problems'. Thereby it may be concluded that the other areas such as health, activities, worries, values and harmful environments ere treated respectively as only a 'subculture'or'fragmentary culture'. The articles containing correlations and interactions among them and certain alternative proposals were very rare. 3) The areas such as 'Worries and Counselling'and 'Health'were occupying only a small portion of the articles. The articles which were treating the practical worries and their resolutions were even rarer. 4) 'Values'of the adolescents tended to be viewed by the older generations very negatively. It was also found that the older generations gave the tendency to see the 'consumption culture'of the adolescents as a kind of 'counter culture'or'subculture'.
