The purpose of this study is to analyze art museum websites and derive implications for future operation of art museum websites. To this end, this research collected basic information about art museums according to '2018 National General Report of Cultural Infrastructure' and investigate the websites of 30 art museums through multi-step sampling process. This study analyzed the structure and menu of the art museum websites as well as the current state of various contents provided by the websites and the search service for the collections offered by the websites. Following sentences are the results. First of all, the art museum websites offer 5.6 top menus on average. Secondly, contents related to art museum, exhibitions, news, education, general forum, and SNS are the basic contents that should be provided on the art museum websites. Third, for contents related to news, education, and events have problems with hierarchical structure and need to be adjusted. Fourth, in the content type, specialized information contents are relatively insufficient and thus need to be improved. Fifth, the art museum websites should give sufficient information about the collection and offer directory searching hat includes keyword searching as well as detail searching service. It is also required to reorganize the directory along with the download function for searched results and the sorting service.

Melatonin is a hormone produced by the pineal gland in dark conditions. It plays a major role in the regulation of the sleep-wake cycle. Melatonin synthesis is known to be suppressed by environmental light. Cortisol is a steroid hormone that is a major indicator of physiological alterations due to stressful stimuli. It also displays a circadian rhythm, like melatonin. The highest levels are encountered during early morning and the lowest levels are observed at around midnight. In the present study, the effects of milking time on the melatonin and cortisol concentrations of raw milk and milk powder at the summer and winter solstices were examined. The melatonin concentration in milk increased significantly if cows were milked in the dark at night (p<0.05). The melatonin concentration in milk powder showed the same pattern with respect to the milking time (p<0.05). However, no significant difference in the cortisol concentration was observed between day- and night-time milk. Although the time of day did not affect the level of milk cortisol, seasonal factors affected the release of cortisol in milk (p<0.05). In conclusion, night-time milk is rich in endogenous melatonin. In this respect, it has potential applications for the development of melatonin rich-dairy products, which serve as natural sources of melatonin.

This study aims to generate digital elevation model from digital satellite imagery. Digital elevation model is being increasingly used for geo-spatial information system database development and for digital map production. Image matching technique was applied to acquire conjugate image coordinates and the algorithm for digital elevation model generation is presented in this study The exterior orientation parameters of the satellite imagery is determined by bundle adjustment and standard correlation was applied for image matching conjugate of image points. The window as well as the searching area have to be defined in image matching. Different sizes of searching area were tested to study the appropriate size of the searching area. Various coordinate transformation methods were applied to improve the computation speed as well as the geometric accuracy. The results were then statistically analysed after which the searching area is determined with the safety factor. To evaluate the accuracy of digital elevation model, 3-D coordinates were extracted from 1/5000 scale topographic map and this was compared to the digital elevation model generated from satellite imagery. The algorithm for generation of digital elevation model generated from satellite imagery is presented in this study which will prove effective in the database development of geo-spatial information system and in digital elevation modelling of large areas.

The current Development Impact Fee (DIF) Zoning Law allows Korean localities to designate the DIF Zone for the areas where there have been up-zoning in land-uses due to any minute additions and/or amendments in the existing clauses or provisions in the National Territory Planning Law as well as all other laws related to urban and regional planning. In reality, however, it is almost impossible to trace the sporadic and infinitesimal changes that might occur in every corner of the statutory clauses of a great number of planning related laws. This study, in an effort to overcome such practical difficulties, tries to chase the time-series zoning alterations in especially the consecutive land-use information layers of the Korea Land Information System (KLIS) as comparable analogues of the outcomes of the amendments in various planning laws. A study locality is chosen among the entire localities in the Capital Region based on the selection criteria dictated by the DIF Zoning Law such as the population- and building permit increase rate. It has been verified that the methodology suggested herein is practically applicable and successfully capable of extracting a number of DIF zones with considerable areal sizes, which could not have otherwise been possible. The consequences of this study, in this context, are expected to contribute to prevent the uncontrolled developments as the DIF Zoning Law itself was originally intended to achieve.

Cultural assets restoration is being considered highly as a practical way to extend the lifespan of damaged cultural assets and re-highlight their value. However, restoration process has been mostly dependent on the manual work involving the experience and skill of a person performing restoration, thereby requiring much time and effort. In recent, it became possible to apply a method allowing restoration to be performed more accurately and easily according to the material characteristics and shape of cultural assets. Namely, it is to use a method of printing out the 3D shape data computed in computer as real object by using 3D printer for the restoration that has been performed manually. The missing part of a cultural asset is computed into computer data first and is printed out by using 3D printer to undergo a simple shaping process. The result of 3D printer application showed that repetitive output and shape and figure revision of digital data were possible, and it was possible to improve the degree of completedness of restoration through test output using various types of restoration materials using various materials. For the purpose of verifying the possibility of applying 3D printer to restore missing part of earthenware, two pieces of modern reproductions, namely, the Seven Treasure Incense Burner and Earthenware with Wagon Wheel Decoration, were artificially damaged. The restoration result showed that compared to manual work, it showed better effectiveness in curtailing work time and reproducing accurate shape. On the other hand, secondary manual work was slightly needed for detailed binding and to vividly express surface texture.

In my paper, the discussion focuses on the fact that sijo is distinguished from free verse as a separate Identity in that it has its own formal beauty, and the works that deviate from this poetic rule are guarded against. In the past ancient sijo, in terms of both music and literature, was a major genre in harmony with chang(songs) ; and in modern times, sijo been created irrelevantly with chug. But my point is that it will not futile if sijo is accompanied with chang, and, therefore, the latter should be adjusted to a modern taste and go together with the former ; and that, to attain this goal, Korean musicans should cooperate with sijo writers. With English-version sijo works, there are some that are put in accordance with the formality of Engish poetry. This paper indicates that, in this case, foreign readers can't feel the nuances the source text of sijo works could produce, so it is not proper to translate sijo works in accordance with the formality of English poetry. But there are other translations where the 3-jang(statements)-6-gu(phrases) form of the original sijo text is reproduced within the limits of English expressions, with each of the two gu(phrases) in a ing(statement) having an almost equal number of syllables, so that each phrase could be recited within the same length of time. The conclusion is that the Korean-English translations of sijo works should begin with the reproduction of its original formal beauty; but, to do this, sijo writers should create works in accordance with it original formality first. Therefore for good translations of sijo works there should be a mutual efforts between sijo scholars and English poetry scholars.

In order to substitute FRP bar for steel bar in new structures, it is necessary to establish a reliable design code. But relatively little research has been conducted on the material in Korea. So, a total of 22 beam specimens (18 GFRP reinforced concrete and 4 conventional steel reinforced concrete) were constructed and tested. In the first phase of the experiment, it was carried out to observe flexural behavior, and collect deflection and crack data. In order to eliminate of the uncertainty by the shear reinforcements and induce flexural failure mode, any stirrup were not used and only shear span-depth ratio were adjusted. However, almost beams were broken by shear and the ACI 440.1R, CSA S806, which were used to design test beams, showed considerable deviation between prediction and test results of shear strengths. Therefore in the second phase of the study, shear failure modes and behavior were observed. A standard specimen had dimensions of 3,300 mm long ${\times}$ 800 mm wide ${\times}$ 200 mm effective depth. Clear span and shear span were 2,800 mm, 1,200 mm respectively. Control shear span-depth ratio was 6.0. Four-point bending test over simple support was conducted. Variables of the specimens were concrete compressive strength, type and elastic modulus of reinforcement, shear span-depth ratio, effective reinforcement ratio, the effect of bundle placing method and cover thickness.

In Western Europo and the US, there has been a general trend over 30 years of reducing the amount of force by the police, through a paradigm shift from 'Escalated Force Model' towards 'Negotiated Management Model'. In tune with this trend, for example, the Swedish Police have implemented the uniformed 'Dialogue Police' system, in order to establish communication contact with demonstrators, before, during, and after their events, The Negotiated Management Model involves a greater respect for the rights of protesters, a more tolerant approach to community, and improved intelligence, communication, and flexibility, in order to facilitate lawful protests and to reduce the possibility of an escalation of major public disorder. The Korean National Police (KNP) appears to be operated within this negotiated management framework, since in preparation for the G20 Seoul Summit, they have also emphasized good communication between the police and protest groups, by newly creating the concept of 'Protest Policing Through Facilitation of Lawful Protests'. In this context, this study first attempts to analyze not only the negotiated management model, but also the Swedish dialogue police. Secondly, the study conducts a comparative study between the KNP's Protest Policing Through Facilitation of Lawful Protest and the Swedish dialogue police system, particularly, in conjunction with the negotiated management. Although Korean and western police have different system and history, protest policing model is now approaching with each other through a link between conflict resolution techniques, such as dialogue, negotiation, mediation and facilitation. Finally, the study is to prove if the KNP's protest policing model corresponds with the negotiated management model, and further to suggest new 'Facilitation of Conflict Resolution Model' as a desirable future of the KNP's protest policing.

Tax assistance system in Korea is a one that is designed by the central government to achieve specific policy objectives through the tax relief for economic activities or specific industries, leading to the development of the industries, Thus, the purpose of this study is to see if the government's direct tax assistance system for small and medium manufacturing firms is effective and then to contribute to establishing necessary policies for an effective tax assistance system based on the identification of a direct assistance system that is substantially useful to those firms. T- test was performed to see if there was a difference in tax burden between small and medium manufacturing firms and small and medium non-manufacturing firms and also to see whether the direct assistance system was effective. The results obtained from the statistical analyses are as follows: (1) The tax reduction rule applied to small and medium firms was turned out to be effective based on the fact that the effective tax rates of the small and medium firms to which the rule was applied were, on the average, significantly lower than those of the Listing large corporation which did not receive the tax benefit and also on the fact that the tax savings rates of the small and medium firms which could apply the rule were, on the average, significantly higher than those of the Listing large corporation to which the rule was not applied. (2) The tax credit rule applied to small and medium manufacturing firms was also turned out effective based on the same fact as described in the case of the application of the tax reduction rule.

To prevent over supplying of workforce with radiologic technologist license, effort to create new jobs related to radioactive from medical field and radiation-related academia should be put first. For this, investigating present condition is required by close analysis of working force supply related to radiation. Therefore in this research, basic data useful for developing future radiation-related policy and plan is provided from analysis of present supplying condition of radiologic technologists in Korea. Results are as following. First, number of people qualified as radiologic technologists consistently increased; 15,639 more people took the license in 2014 compared with 2004, showing growth rate of 75.6%. Second, about 65.7%, most of workforce related to radiation engaged in medical area. Third, estimating supply and demand of radiologic technologists by time period of 5 years from 2015 to 2040, about 6,000 number of surplus work force was predicted around 2020. Fourth, satisfaction of graduates who majored in radiology was quite low for their first occupation. These results implicate necessity of systemic supplementation which can expand medical areas where radiologic technologists can work.
