Since 2016, the VR market has been on the rapid growth. The most critical and arising issue in the VR market is VR contents. That is because it is necessary to develop making techniques and various VR contents to satisfy users' immersion and interaction as much as possible. Therefore, this study focused on VR image contents, conducted domestic and foreign cases of the components of visual and auditory inducement to keep and improve immersion, and thereby tried to find a right direction of visual and auditory inducement. As a result, the visual and auditory components of visual and auditory inducement were found to be photographing, edition, lighting, stitching, graphics, effect, voice actor's narration, dubbing, character voice, background sound, and sound effect; its technical and content components were found to be photographing technique, edition technique, lighting, stitching, graphics and effect, sound and sound effect, and theatric direction based on Mise-en-Scene, lines and narration of characters, and movements of characters and objets. For VR image contents, not only visual and auditory components, but technical and content components are necessary to improve immersion. In the future, it will be necessary to continue to research them.

^x As mentioned above, I consider the change of role that is related with Japanese thought of Natural Environmental Conservation, and I divide each part of periods into forest, farmland, open space, urban planning, environmental conservation etc. To summary the content of each period of Natural Environmental Conservation thought is as follows. 1) Previous period before formation(before 1919) In the previous period of Meiji, it could be said that the consciousness of the Natural Environmental Conservation was coming to existence. In this, so called, Natural Environmental Conservation, the thought of Forest Preservation was the main current and it was the thought of territorial integrity for the security of resource, the forestry conservancy and flood control in the forestry farmland. Since the age of Meiji, the theory of Natural Conservation appears from the theory of Japanese landscaping and systematic management about public parks was enforced, but the regular theory of Natural Environmental Conservation did not attain full growth. 2) The period of formation(1919~ 1954) In the period of formation, the base of Natural Environmental Conservation had been established. Parks and Open spaces were admitted as a public facilities in each city, and legislations which supported it had been continuously enacted and so on. In this period, the afforestation counter plan was emphasized on the side of territorial integrity. In the mountainous district. tree planting was emphasized to recover the forest which had been destroied by war. 3) The period of development(1955~ 1974) In the period of development, varied policies was institutionalized for the Natural Environmental Conservation. However, all sorts of development policy had performed simultaneously, thus development had complicated relation with preservation. But after 1970's the framework of system of Natural Environmental Conservation improvement was constituted to control the many kinds of development, and the spontaneous campaign of nature preservation by private lead was being taken root. This is the more progressive period. 4) The pried of root(after 1975) After the latter of 1970's, the role of Natural Environmental Conservation began to take root not in the direction of control but inducement, and, getting out of development - oriented policy, aimed at relation between human being and natural environment and the side of amenity of human environment. Besides, the current of Natural Environmental Conservation had been seperately progressed in the cities and forests. Since this period, it was the character that cities and forests began to be unified as 'amenity'space of man.

As Korea experienced a Asian foreign exchange crisis in 1997 and a world financial crisis in 2008, the social structure of Korea has undergone many changes. The problem of polarization has become more serious, and the social class has become harder to move between strata. This problem has been accompanied by a growing sense of crisis that the power of social development can be lost along with the problem of population cliffs. Behind the crisis is a reflection of the fact that the growth-oriented economic policies and welfare policies implemented in various European countries can not solve the problem. As an alternative to this, the emergence of social enterprises is attracting attention. Social enterprises have the characteristic of seeking to generate economic profit in order to achieve the purpose of the public interest to provide jobs to the underprivileged. In recent years, the importance of social ventures to expand the scope of new social enterprises in innovative ways has increased. The social venture is a venture business in that it takes risks to develop new areas, not existing business areas, but it also has the character of a social enterprise to achieve the public interest. In other words, an innovative corporate model that provides a creative and challenging solution of social problems in the venture spirit. Although the interest and importance of social enterprises and social ventures are increasing, this academic research is still lacking. The purpose of this study is to introduce and analyze cases of successful social enterprises and social ventures in order to reflect these social interests and their importance and to fill the gap of previous studies. In addition, I hope that this study will stimulate interest and research on the start - up of social venture.

Experiments were conducted to investigate the population fluctuation, developmental periods, fecundity, hatching rate and demage of Citrus red mite (Panonychus citri M.) on Yuzu trees (citrus junos T.) from 1996 to 1997. Citrus red mite occurred from May to November and made two peaks. The first peak was in July to August and the secondary peak was in October. Density of the second peak was higher (9.5 miteslleaf) than that of the first peak. In the constitution rate of each developmental stage of citrus red mite on Yuzu leaves, egg stage occupied 85%. At the four constant temperature (15, 20, 25, 30 + 1$^{\circ}$C, RH 60 + lo%, 14L- IOD) conditions, the developmental period from egg to adult was 41 .l, 15.5, 11.0 and 9.4 days ; Mean longevity of adult was 23.3, 8.3, 6.3, and 6.1 days; Mean number of egg laid per female per day was 1.6, 3.2, 4.5, 4.0 eggs; Mean hatching rate was 66.6, 85.7, 90.7 and 94.7% at above temperature, respectively. When sprayed acaricide at different density of Citrus red mite, the growth of young Yuzu tree were better at low density. Defoliation rate during winter was 13.5, 20.6, 53.1, 72.6% at 4 control density 1 , 3, 6 mites per leaf and uncontrolled (10 ( ). When every time spray acaricide under 3 mites per leaf, defoliation rate during winter suppressed above 50% compare to uncontrol 72.6%.

Barley Yellow Mosaic Virus (BaYMV) caused significant reduction in barley yield and is difficult to control due to alive parasitic soil-borne fungus, Palmyra gamines that transmits the, virus. Previous studies have indicated that a virus-free soil could be infested by using virus-contaminated farming machineneries and implements. For the further confirmation of this finding, different proportions of BaYMV-infested soil were mixed into virus free soil. Three barley varieties (Hordum vulgarae, cv "Olbori", "Baegdong" and "Sacheon 6") were sown in pots treated with different rate of P. graminis-infested soil ranging from 0% to 100% in October 20, 2001. Results showed that BaYMV infection increased as the rate of infested soil increased. Initial symptoms were observed in a pots treated with 10% infested soil in all the 3 varieties of barley. "Olbori" had about 5% infection in 20% infested soil and about 10% infection in 40% or 50% infested soil and about 20% infection in 60% infested soil. In "Baegdong", the trend of BYMV occurrence was similar with "Olbori" but the time of severe infection was earlier than "Olbori". BaYMV infection in "Sacheon 6" was even earlier than "Baegdong" with much more severe symptoms than "Baegdong". The growth rate of barley was affected by about 19-22% when grown in 20% infested soil. As the rate of BaYMV infested soil increased the heading date was delayed but the maturing date was early in "Olbori" and "Sacheon 6". Also, reduction rate of culm length in 3 varieties increased with increase of infested soil content. However, "Olbori" showed the highest reduction. "Sacheon 6", have been characterized with long spike length, however was significantly reduced as the infested soil increased. On the other hand, spike length of "Olbori" was not significantly affected despite of increased of infested soil. The reduction rate of 1000 kernel weight was higher in large kernel size cultivar "Sacheon 6" and "Olbori" than small kernel size "Baegdong" as increase of BaYMV-infested soil content.

The archives and records management 'reform' has spreaded out through the third quarter of 2004. There are many evidences such as the change of the Office of the President's management on the record production, 'the reforming road map for the final draft on the archives and records management.' This method spreads into the Cabinets. So it is improved these rosy conditions was upgraded by the laws and regulations. We also hope that the conditions of the records management to be a higher level than before. However the actual conditions of the records management are not good comparing with the law and regulations. I think this unbalance is a serious problem. The reason of the 'failed history' during past time was caused not by the laws itself but by the indifference and negligence on the laws. The academic field and NGO have continuously required some essential suggestions on that problem; political neutrality and independent of the National Archives, the employment of specialists and the improvement of their skills etc. But these requirements have not accepted yet. This revised records management law also has not applied to the road map wholly. Even though the outward growth during that time is remarkable, we need to learn some instructions by way of the 'failed history'. Therefore our urgent task is to narrow the gap between the new system and the actual conditions based on long and short term projects.

In this paper, I found the leadership core-value of the Sunbai(선배) a man of refined taste. I studied twelve Sunbai considered as a man of refined taste in this research. I focused on the aspect showing common worth among their various abilities and cultural contributions, a point of view of classifying them into one form called Sunbai a man of refined taste. As the core value is the basis of supporting the individual identity, so the leadership core-value is the source and philosophical base of displaying the leadership. Our Sunbai combining character and knowledge show common structure in their personal growth and showing the leadership. It is that they embodied the stage of cultivating themselves(修身, Self), considering the relation with others(齊家, Relation), leading the organization(治國, Team), and making efforts for and having influence on the community(平天下, Community) throughout their own life. I examined how to display the leadership in the four fields on a case by case basis and then constructed the leadership model of the Sunbai a man of refined taste by synthesizing them. As a result, I considered their leadership core-value as the intercommunication and named it 'Leadership of Muaesabang(無碍四方)'. Also, I confirmed that it is still very valuable in these days of aiming at the open society and the harmony of the diverse civilization.

The purpose of this study is to identify trends and potential themes of research on consumption of children and adolescents for 20 years by analyzing keywords. The keywords of 869 studies on consumption of children and adolescents published in journals listed in Korean Citation Index were analyzed using text mining techniques. The most frequent keywords were found in the order of youth, youth consumers, consumer education, conspicuous consumption, consumption behavior, and character. As a result of analyzing the frequency of keywords by dividing into five-year periods, it was confirmed that the frequency of consumer education was significantly higher betwn 2006 and 2010. Research on ethical consumption has been active since 2011, and research has been conducted on various topics instead of without a prominent keyword during the most recent 5-year period. Looking at the keywords based on the TF-IDF, the keywords related to the environment and the Internet were the main keywords between 2001 and 2005. From 2006 to 2010, the TF-IDF values of media use, advertisement education, and Internet items were high. From 2011 to 2015, fair trade, green growth, green consumption, North Korean defector youths, social media, and from 2016 to 2020, text mining, sustainable development education, maker education, and the 2015 revised curriculum appeared as important themes. As a result of topic modeling, eight topics were derived: consumer education, mass media/peer culture, rational consumption, Hallyu/cultural industry, consumer competency, economic education, teaching and learning method, and eco-friendly/ethical consumption. As a result of network analysis, it was found that conspicuous consumption and consumer education are important topics in consumption research of children and adolescents.

Development of soybean cultivars with great nodulation and high nitrogen fixation activity, derived mostly from mutagenesis, may decrease inputs of chemical fertilizer nitrogen into the soil-plant system. Soybean seeds (cv. Jangyupkong, Hwanggeumkong, and Geomjungkong 1) were treated with three different levels of EMS (ethyl methanesulfonate) concentration(30, 50, and 70mM). Increasing the doses of EMS resulted in decreased field emergence rate of seeds, whereas it did not increase M$_2$ mutation frequencies. This indicated that the most efficient concentration of EMS was 30mM for generating mutants. Extensive mutagenesis of Sinpaldalkong 2 with 30mM EMS was undertaken to isolate soybean mutants with greater nodulation. Approximately 8, 200 M$_2$ families were screened for greater nodulation on 5 mM nitrate after inoculation with Bradyrhizobium japonicum strain YCK213-KFCC-10728. Mutant SS-2 nodulated more than the wild type. Comparison of supernodulation between SS-2 and two nts mutants(nts 1007 and nts 1116) revealed that SS-2 showed the supernodulation character at an earlier growth stage than the two nts mutants. Further studies should be needed to characterize the difference in timing of nodulation between SS-2 and nts mutants.

Due to high cost of domestic production structure, steep growth of China's manufacturing business, and increase in oversea's production, building integrated system to support user-centered product design system based on cognitive and affective information is required to restore development of domestic manufacturing business. This paper put purpose on analysing requirements of end users, especially on information equipment business which works as a major industry in manufacturing businesses, and planning system design direction, prior to constructing user-centered product design support system based on cognitive and affective information. Research was conducted to identify current manufacturing process, application data on manufacturing, availability of cognitive and affective information data and its method of use, and necessity of user-centered product design support system based on cognitive and affective information, by carrying out in-depth interview with 6 related manufacturing companies. Need for user's character information was deducted from the interview, especially cognitive and affective information which is demanding for small to medium manufacturing business to research on its own.
