Recently, due to the global economic crisis and prolongation of slow growth period, many countries have proposed creative economy as an important policy for economic growth. Korea has also progressed important policies such as development of creative industries, start-up activation and employment creation through creative economy as a key policy. However, each country has a different definition of creative economy and detailed field to promote, and there is a lack of research on creative economy of industrial complexes and activation plans of creative industries. This study derived the priority order and importance of development plans to develop into creative clusters through AHP analysis base on Gumi National Industrial Complex that have had a significant role in the national economy since the 1970s. As a result, the creativity enhancing factor was the highest priority, followed by creative infrastructure and network. These results mean that it is necessary to promote creativity in order national industrial complexes to continuously lead national economy and for this purpose it needs to prioritize the development of creative human resources and to extend the creative R&D. This study can be provided to government and local policy makers and innovation agencies as basis data and practical policy guide to establish a successful creative cluster by deriving the priority order in reflection of both hardware and software policies such as infrastructure to develop national industrial complex into creative cluster.

The early history of foreign Protestant missionaries in Korea has begun in the late 19th century, when they came to work as professionals such as teachers, medical doctors, etc. as the nation opened its door to western culture with the fall of national isolationism. Their records are considered crucial resources that enable us to shed new light on modern Korean history, politics, economy and society beyond mere religious value. Despite the recognition of such historic value of early missionary resources, however, there has been serious lacking of a systematic attempt to develop policies and plans for making it easy to collect, preserve and access the resources. Up to date, the records of early Protestant missionaries, in diverse forms of mission reports, books, periodicals, personal diaries, letters and photos, are scattered around various places, including their home country churches, governments, libraries, museums, research institutes and homes. Therefore, this research aims at providing basic resources on the archival status of early Protestant missionaries in Korea, needed for developing a sustainable and systematic digital archive system, through the investigation of early foreign missionaries' resources and in-depth interviews of experts. The study covers the period of 1800s to 1910, that is from the beginning of Protestant missionaries entering into Korea until the start of the Japanese annexation in 1910.

This study seeks to identify the effects of light pollution and environmental factors on Great Tits(Parus major) bird's chirping at dawn. For this research, the campus of Sanji University, Wonju, South Korea was selected as the area with light pollution and the western forest of the Chiaksan National Park was chosen as the natural area herein. The Recording period was between March 26th and May 30th, 2014. As a result of analyzing the chirping time according to light pollution, it was found that the light pollution area clearly showed earlier chirping time than the natural area (p<0.05). Great Tits(P. major) normally start their first chirping before sunrise and in most of the days under investigation of this research, those in Sanji University started to chirp earlier. This faster chirping time seems to improve the chance for the female birds to mate with immature males thus, baby birds hatch earlier than the appropriate breeding season and results in the lack of feed resources. The correlation between Great Tits'(P. major) dawn chirping and environmental factors were investigated herein including the time of sunrise, civil twilight, navigation twilight, astronomical twilight, average temperature, highest temperature, lowest temperature, time of moonrise and cloudiness. The first chirping time of wild birds in the day was found to have correlations with all of the environmental factors excluding the time of moonrise and cloudiness. Great Tits(P. major) started their first chirping before sunrise when the day started to break around civil twilight. Along with the earlier sunrise and higher air temperature, their dawn chirping time was also quickened. The time of moonrise and cloudiness did not show a correlation and further follow-up studies will be necessary in this regard.

The field scale experiment was performed to examine the effect of plant coverage on the constructed wetland performance and recommend the optimum development and management of macrophyte communities. Four sets (each set of 0.88 ha) of wetland (0.8 ha) and pond (0.08 ha) systems were used. Water flowing into the Seokmoon estuarine reservoir from the Dangjin stream was pumped into wetland system. Water depth was maintained at 0.3 ${\sim}$ 0.5 m and hydraulic retention time was managed to about 2 ${\sim}$ 5 days; emergent plants were allowed to grow in the wetlands. After three growing seasons of the construction of wetlands, plant coverage was about 90%, even with no plantation, from bare soil surfaces at the initial stage. During the start up period of constructed wetlands, lower water levels should be maintained to avoid flooding newly plants, if wetland plants are to be started from germinating seeds. Effluent T-N concentration in low plant coverage wetland was higher in winter than high plant coverage wetland, whereas no T-P effluent concentration and removal efficiency difference was observed within 15% plant coverage. Dead vegetation affected nitrogen removal during winter because it is a source of organic carbon which is an essential parameter in denitrification. Biomass harvesting is not a realistic management option for most constructed wetland systems because it could only slightly increase the removal rate and provide a minor nitrogen removal pathway due to lack of organic carbon.

This study was conducted to improve the insufficiency of fruit vegetable grafting system developed by National Institute of Agricultural Sciences, Rural Development Administration. When the rotary blade cut the stem of scions and rootstocks, the grafting failure at curved cutting surfaces happened. The cutting depth of a tomato seedling by a rotated cutter was calculated 0.11 mm even when the cutting arm length and the maximum stem diameter were 50 mm and 5 mm, respectively. Mathematical analysis and high-speed photography showed that there was no problem by cutting in straight the stem of scions and rootstocks. The compression test of seedling stems to design the optimal shape of gripper showed that stems were not completely restored when they were compressed above 0.8 mm and 0.6 mm in case of rootstocks and scion, respectively. This study found that the bending angle of stem of tomato seedlings at the grafting period was 10 degree on average. The optimal gripper finger was the edge finger type which could be precisely set center point by adjusting the distance between fingers. In addition, it was found that most of seedling could be grasped without damage when the finger-to-finger distances is set to 2.5 mm for scion and 3.0 mm for rootstocks and finger are coated by 1 mm-thick flexible material.

The biodegradability in water of the artificial baits for blue crab pots which were made of intestines of mackerel, tuna and grinded krill were studied. The biodegradability of artificial bait was evaluated with the effective capacity of 10L water tank which was made of acryl pipe at the velocity of 1m/d and hydraulic retention time of 12 hours. For the 23 days operation time, all artificial baits were degraded fast at the early stage of operation time and stabilized within 5 days after start up. The rates of biodegradation were different depending on the raw materials of artificial baits. In terms of degradation rate of organic matter which can be expressed as COD, artificial bait made of tunas intestine showed the fastest degradation rate. On the other hand, in terms of degradation rate of nitrogenous matter which can be expressed as ammonia nitrogen, artificial bait made of mackerels intestine showed the fastest degradation rate. In order to evaluate the effect of artificial bait on marine ecosystem, seawater qualities including SS, COD, DO, nitrogen, phosphorus were determined depending on depth and location during 2 days test operation period. It is apparent that the effect of artificial bait on seawater quality was negligible when comparing seawater quality of test operation area with control area.

The chemical components of four muskmelons (Thankyou, Beauty, Picnic, and Symphony), according to the cultivars, were investigated during storage at $7^{\circ}C$ for 28 days. After the storage period, the Picnic cultivar indicated a weight decrease of up to 4.70% whereas the Symphony cultivar showed the best weight maintenance during storage (1.02%). The Thankyou and Symphony cultivars had higher sugar content and acidity levels than the Beauty and Picnic cultivars during storage. While the Symphony and Beauty cultivars showed high hardness at the start of their storage, their hardness decreased much during storage while the Thankyou and Picnic cultivars showed little change in hardness during storage. Further, the Thankyou cultivar not only maintained its unique muskmelon yellow color but also showed lower microorganism growth than the other cultivars. The stem water loss seen in this cultivar, however, tends to be the first thing seen by the consumers and may thus determine its merchantable quality. In addition, as the Thankyou cultivar showed the least quality change during storage, it will be useful for the development of a technology for minimizing the moisture content of a muskmelon's stem.

To insure nuclear reactor safety, the reactivity of control rods should be calculated by measuring the criticality of reactor core and it is regularly performed during the annual physics test period. Also, the core criticality should be monitored during the start-up operation to avoid reactivity induced accidents. Many research works on control rod reactivity measurement and subcriticality measurement have been accomplished throughout the world for decades and recently a new method named "Modified Neutron Source Multiplication Method (MNSM)" was proposed in Japan which is known to be improved overcoming limitations of traditional Neutron Source Multiplication Method (NSM). In this study, MNSM was tested in calculation of subcriticalities and in evaluation of application validity using the educational reactor in Kyung Hee University, AGN-201. For this study, a revised nuclear data library and a neutron transport code system TRANSX - PARTISN were established. Correction factors for various control rod positions were produced using the k-effective values and the corresponding flux distributions and adjoint flux distributions. Experimental values of the core criticality were obtained using the neutron count rates of the BF3 proportional counters. The results showed that the expected reactivity worth of control rods by MNSM agreed well with the theoretical values and the correction factors contributed much for this purpose.

This is the study on the 'Theater State' in the Daehan Empire of the Emperor Gochung in the late 1900 with the theatrical concepts of cultural performance theory which has been useful for investigating historical, social, and cultural collective memories and their transformation mechanism in the society. The performance theory is based in the notion, '$Performativit{\ddot{a}}t$', by which the performance can contain vary performance forms. $Performativit{\ddot{a}}t$ is the notion which points up the certain process that can cause the perceptional emotion communication to the performers and audiences in the performance. The spectacle of a society is also understood and presupposed by the $Performativit{\ddot{a}}t$. Generally speaking, the spectacle has been used of explaining the visual cultural experiences in society. Fundamentally, spectacle had resulted from the latin 'spectaculum', which was used to designate theatrical representation in France. In the case of movie, spectacle was the grand show with showy technological attractions. The spectacle have been to show the political and socio-historical relationships in a society. But in my study, I want to start the premise that the cultural performance planed by the Emperor Gochung in the Daehan Empire has the attribute of 'theater state', which can awaken the certain collective emotion to connect the Emperor and his people in the Daehan Empire period of the Emperor Gochung of the late 1900. In addition to it, I search for the historical collective memories of the Daehan Empire. The government of the Daehan Empire was continuing with its efforts to enforce and recollect the imperial images and authority of the Emperor and his Empire to get the approval of the people and international society. The effect of spectacle consisting of theater state was the concrete effort to establish the collective memories of the Daehan Empire by remodelling and rebuilding the Seoul, the capital of the Empire and performing the national ceremony such as the korean pagent(Gae-Dung거둥) and parade to set the portrait of the Emperor(A-Jin어진), the geo-body of the Empire.

This study attempted an empirical analysis study on the Meal Kit Product, whose interest and demand continued to increase according to the eating out trend in the Untact era. In addition, this study attempted to investigate the relationship between the factors of Home Meal Replacement Meal Kit Product Selection Attributes, Consumers Satisfaction, and Other Recommendation Intention. Convenience sampling was used for consumers with experience in using Meal Kit Products released by food service companies and start-up companies. The investigation period was conducted for about one month from July 01, 2020, and the final 285 copies were used for analysis. The SPSS 21.0 statistical package program was used to verify the hypothesis. As a result of the analysis, the price (β=.241), convenience (β=.317), and diversity (β=.191) of Hypothesis 1 had a significant effect on Consumers Satisfaction. Price (β=.482), convenience (β=.133), and diversity (β=.342) were found to have a significant effect on the intention to recommend others. It was analyzed that Hypothesis 3's Consumers Satisfaction (β=.443) had a significant effect on Other Recommendation Intention. Finally, through this study, we expect to be provided as basic research data related to Meal Kit Product. It is intended to be presented as a theoretical basis for the use of marketing and direction for the development of milk kit products for catering companies and restaurants.
