Since its introduction in Korea, design VE has widely been used as a means to enhance values in the construction industry. However, a greater emphasis is still placed on cost reduction in approach attitudes and performance evaluations on the implementation of design VE. In this regard, this study presented a performance evaluation method for cost, function, and value of VE proposals. Numerical criteria on the increase and decrease of cost and function that can classify the value enhancement type of VE proposals were proposed based on the performance evaluation method. It is expected that the use of numerical criteria for the type classification of VE proposal, and cost and performance evaluation method proposed in this study will make it possible to conduct a clear and more intuitive evaluation of VE proposal. However, it is appropriate to use the numerical criteria as a guideline to apply the new performance evaluation method for VE proposals. Therefore, it is necessary to conduct a statistical analysis with a wider range of users after the repeated application of the findings of this study, and thus to carry out research for presenting the numerical criteria for various types of users.

The capacity of Jeju International Airport has reached its limit due to a surge in air traffic demand such as passengers and cargo and the continuous expansion of Low Cost Carriers (LCC). Despite COVID-19 that has began in November 2019, Jeju International Airport still has continuous demand in terms of passenger and cargo transportation. As a result, it is undeniable that the delay rate also unexpectedly increased as the air traffic volume at Jeju International Airport continued to increase. In this study, the correlation between Turnaround Time and delay rates of national airlines is analyzed based on past flight data at Jeju International Airport, and the cumulative delay time trend for sampled airlines is compared with Turnaround Time. Through this study, it is expected to contribute to securing aircraft operation efficiency and on-time by analyzing delays related to Turnaround Time at Jeju International Airport.

Dressmaking is a high value-added sector of the fashion industry in which the individuality and skills of designers play a prominent role. The appropriate use of the draping and the flat pattern techniques in the dressmaking process also play an important part in perfecting the finished product. The purpose of this study was to improve the understanding of dress design and identify a pattern production technique to enhence efficiency in each of the three elements of the dress manufactureing process. For this purpose, analysis of the design of 1,389 wedding dress photographs published in Wedding 21, Korea's leading wedding magazine, during 2019 and 2020 was conducted. This analysis identified 15 bodice designs and 11 sleeve designs based on neckline and eight skirts based on silhouette which were ranked by frequency distribution. Patterns for the design of samples were then developed according to the highest combined frequency distribution of these three elements. Eight samples were finally produced to test the the efficiency of the patternmaking techniques empolyed and the selected designs. The findings from this study have practical applications, notably in improving the efficiency of pattern production techniques that will facilitate further growth in the dressmaking industry.

Endophytic fungi are present in host plants and contribute to resistance to biotic and abiotic stress. Aquatic plants are living in aquatic environment such as saltwater or freshwater and exposed more water stress than other land plants. In this study, we investigated 4 wetlands in Jeju and collected 11 aquatic plants. Exogenous microbes were removed by preprocessing of plants and endophytic fungal strains were isolated from the plants. We isolated 126 fungal strains from Namsaengi-pond, 22 fungal strains from Sujangdong-marsh, 44 fungal strains from Yongsu-reservoir and 32 fungal strains from Gangjeongcheon. The fungal strains were identified using internal transcribed spacer (ITS) region and analyzed the phylogeny and diversity. Endophytic fungi isolated from plants of Namsaengi-pond were classified to 30 genera, 19 families, 12 orders, 7 classes and 4 phyla. Endophytic fungi of Sujangdong-marsh were classified to 11 genera, 11 families, 6 orders, 5 classes and 4 phyla. Endophytic fungi of Yongsu-reservoir were classified to 13 genera, 12 families, 7 orders, 5 classes and 4 phyla. Endophytic fungi isolated from Gangjeongcheon were classified to 9 genera, 7 families, 5 orders, 2 classes and 1 phyla. Overall, they were divided 40 genera and Alternaria, Colletotrichum and Fusarium were isolated from 4 sites in common. By investigating the endophytic fungi in aquatic plants, it is for baseline data that determination of diversity and the ecological distribution of endophytic fungi.

JeJu Island is famous for beautiful scenery but relatively little attention was paid to social cultural attractions. My aim is to provide an alternative attraction for JeJu destination. Two main goals of this paper are to apply to the Pine and Gilmore Experience Economy Theory framework on performance arts experiences and identify causal relations among experience factor, experience satisfaction and performance loyalty. To accomplish the study object, theoretical review and empirical analysis were jointly carried out. Using samples of 280 participations in nonverbal comic performance 'Nanta' who were required to rate performance experiences, experiences satisfaction, and performance loyalty. Results of SEM(Structured Equation Model) was showed that only Entertainment factor of 4 experiences factors(aesthetics, entertainment, education, escapist) affected experiences satisfaction. While experiences satisfaction affected performance loyalty. These results support the concept of experiential Economy framework suggested by Pine and Gilmore on culture-arts products consumption.
