A new commercial strain 'Garlmoe' was developed by crossing monokaryons from selected wild strains. The optimal temperature of mycelial growth was $25^{\circ}C$ but it needed to adjust to $16{\sim}18^{\circ}C$ when incubated at the bottle cultivation. The optimal temperatures of fruiting body initiation and development were almost same to others like as $14^{\circ}C$ and $7{\sim}10^{\circ}C$, respectively. The color of 'Garlmoe' was typical to wild winter mushroom, that is, pileus was brown and lower part of stipe was dark brown. The surface on pileus of 'Garlmoe' was sticky 'Garlmoe' was a good commercial strain with high quality and high productivity characterized as quite even budding habit, straight and strong stipes and convex type pilei. The taste of this variety was very excellent because of better chewing feeling than white ones.

General characteristics and life span of silkworm moth were investigated amongst 277 gene resources preserved and maintained in Korea. Silkworm varieties were classified according to the commercial characteristics and the viability of tested varieties. There were significant differences among the eight different commercial characteristics of silkworm such as whole larval period, duration of 5th instar, pupal body weight, single cocoon weight, cocoon shell weight, cocoon shell ratio, cocoon yield and longevity, Tropical race showed the longest life span among the other five geographical races, and followed by Japanese, European, Chinese and Korean race in order. In the longevity of each variety, Daizo(sdi) showed the shortest life span with 4.3days, and J037 was the longest as 16.0 days. Average longevity of female was 11.1 days as showed 3.0 days longer than that of male which was 8.2 days. Total average longevity of the whole varieties was 9.7days. In the correlation between the longevity and commercial characteristics, there was a tendency that the commercial characteristics became better when the life span was longer. According to the result of Complete Linkage Cluster Analysis, the genetic resources of 277 silkworm varieties classified into 5 groups such as “Group I”for short life span with low cocoon yielding “Group II”for middle life span with middle cocoon yielding,“Group III”for the shortest life span with low cocoon yielding, “Group IV”for high pupation rate and the highest cocoon yielding with comparatively long life span, and “Group V”for the longest life span with comparatively high cocoon yielding.

This study was conducted to reduce the phenomenon of the biased cultivation of certain mushroom varieties and to develop a competitive variety of Grifola frondosa. We developed the first Korean white commercial mushroom strain, 'Bakyeon', by crossing monokaryons derived from brown strains. We have collected and tested the characteristics of mushrooms from domestic and international genetic resources since 2018. We bred the unique domestic variety, 'Bakyeon', which has the following characteristics. The optimal temperature for mycelial growth was 25~28℃ and the optimal temperature for fruit body growth was 16~18℃. The new variety was similar to the control variety (Daebak) in terms of the pileus, which formed a pine cone shape, and the number of days of cultivation. The yield was 94.1 g/bottle, which was 23% lower than the 108.5 g/bottle yield of the control variety. When incubating the parent and control varieties, the replacement line was clear. Moreover, polymerase chain reaction analysis of mycelial DNA resulted in different band patterns between the parent and control varieties, confirming the hybrid species.

Although ear mushroom (Auricularia auricula-judae) is cultivated worldwide, there are a limited number of commercial cultivars in Korea. Recent increase in the import of ear mushroom from China threatens the domestic farming. The present study introduces a new thermotolerant cultivar of ear mushroom, designated 'Hyeonyu', developed by mating monokaryons obtained from JBAA11 and CAA1 strains. The optimal growth temperature for Hyeonyu was 26-36?. The periods of primordia formation and fruit-body growth were 27 and 15 days, respectively. The average mushroom yield per bag (1 kg) was 350 g. Random amplification of polymorphic DNA (RAPD) analysis with OPA1 and OPA7 primers identified polymorphic DNA bands between the control, the new variety Hyeonyu, and a Chinese variety.

The purpose of this study is to provide the information about improvement method of the detached housing area for children's outdoor activities. This study was accomplished by two research methods; the evaluation of physical environment of two detached housing areas, and the analyzation of satisfaction & consciousness of 190 residents. Outdoor spaces of detached housing area were divided into 6 areas (play space, education facility, commercial facility, green space, street space, and empty space & parking lot). And then, 6 outdoor spaces were evaluated about the physical characters such as accessibility, network, safety, variety, functional, natural elements. Also, the survey for resident's satisfaction and consciousness was used the Likert scale. According to the result of this study, many parts of the detached housing area were not good for children's outdoor activities, and the resident's satisfaction was low. In the sample detached housing areas, negative factors were car and motorcycle. And many residents pointed out the lack of natural elements, variety, and safety of outdoor space in dwelling area. Finally, this study suggested the several constitution method for the children's activities based on the results of evaluation and survey.

This study was performed to investigate nutritional effect and the utilization possibility of rapeseed oil which could replace the imported edible oils and oil crops. The proximate compositions of a recommendable cultivar(Mokpo Dangyo 19) and a native kind(Asahi) and the characteristics of these rapeseed oils were analyzed. The animal experiment of these rapeseed oils was carried out during 8 weeks of growing periods after weanling. Forty male weanling Sprague-Dawley rats were randomly assigned to 3 diet groups of Dangyo 19 oil, Asahi oil and commercial Soybean oil. Mokpo Dangyo 19 variety contained more lipids than Asahi variety by 8% and there was no difference in physiochemical characteristics between Dangyo 19 oil and Asahi oil except that erucic acid was contained little in Dangyo 19 oil but 50% in Asahi oil. Body weight gain, FER(Feed efficiency ratio) and PER(Protein efficiency ratio) of rats fed Dangyo 19 oil were higher than those of rats fed Asahi oil and organ weights such as liver, kidney and epididymal fat pads weights of rats fed Dangyo 19 oil were significantly higher(P<0.05) thanthose of rats fed Asahi oil. the apparent digistibility of total diet and total lipid were higher in rats fed the diets containing Dangyo 19 oil than Asahi oil. The content of total lipid in heart in heart were not significantly different with dietary oil kinds. The content of total lipid in liver increased with age in all rapeseed oil groups.

The purpose of this research is to valuate the economic value of the arboretum which will be provided in Multifunctional Administrative City by estimating citizens' willingness to pay with double-bounded dichotomous choice contingent valuation method, and to provide the basic information necessary for designing and managing it for the future by identifying the types of the variables affecting the WTP. It was found that respondent's average WTP for arboretum was \23,508, and when this figures applied to all the Seoul citizens aged between 20 and 59, the economic value of it was \157,000,000,000. The variables affecting the amount of WTP were visit intention, variety seeking tendency, level of income and environmental attitude. However, environmental attitude negatively affected the amount of WTP. Average WTP for the entrance fee was \5,090, and both variety seeking tendency and visit intention were influencing factor affecting the amount of WTP. Respondents were taking charging entrance fee for granted because most of arboretums are commercial. It can be expected that much of maintenance cost will be covered from the entrance fee.

As intellectual property rights are perceived as the key element of creating added values and securing competitiveness, the result of intellectual property rights disputes play an important role in the success of companies. As seen from above strong points of an Alternative Dispute Resolution (ADR) system in Chapter III, intellectual property rights disputes increasingly tend to be resolved by ADR rather than litigation. Discussions about and operation of ADR are already being actively carried out in many countries, and major ADR institutions have been acquiring experience in a variety of intellectual property rights disputes. To enhance the use and recognition of ADR as the way of resolving the Intellectual Property Rights disputes in Korea, this study suggested the following three ways. First, domestic ADR institutions, the Korean Commercial Arbitration Board (KCAB) will need to establish cooperative systems with prominent overseas institutions to lead the disputing parties to fair resolutions as well as to instill trust in international arbitration institutions. Second, they will need to contribute to the promotion of arbitration systems throughout society by developing and applying a variety of arbitration systems as well as securing a pool of professionals. Finally, the arbitration rules will need to be continuously improved to deal with disputes promptly and reinforce privacy protection.

In the 21st century, modern society is rapidly changing paradigm of environment with advancement of advanced technology and improving income levels. Such a paradigm reflected in modern design and emerged as a new spatial aspect through various cultural and artistic expressions, thus becoming a crucial role in commercial space. Reflecting on this phenomenon, fashion brands have expanded the concept of a variety of cultural, artistic, and experience cultures with a variety of cultural and artistic sectors in each of the world's major cities. The fashion companies began to focus on fashion programs featuring "Funology" as the fun which creates a sense of curiosity rather than a meaningless space and a fun experience. Therefore, this study analyzes the spatial characteristics of fashion flagship store sites using characteristics of fashion flagship store presented in the expressions of fashion, and analyzes the spatial characteristics of the fashion flagship store based on the spatial characteristics derived from the spatial characteristics of the fashion scene. Based on these results, we confirm the relationship between the Fashion Flagship and the Funology. Design Aspects of the Fashion Flagship Store with Elements of Fun and We expect continuous research as a strategic factor that provides limitless ideas for many design and creative activities.
