Many of the patients with extensive abrasion need comprehensive restorative treatment. The abrasion is usually caused by attrition, besides of it, there are many reasons for it. The plan of treatment should be started on assessment of the type of attrition and the etiologic analysis. Patient with well-developed masticatory muscle, alveolar process, and high occlusal force and also with little muscle length difference between the stable and the contracted state should be carefully assessed for the vertical dimensional loss and the restoration should be carefully designed. Decrease of tooth length can be compensated by the growth of the alveolar bone height; therefore, consistency of the occlusal vertical dimension is maintained. Accordingly, a careless increase of the vertical dimension can produce muscle fatigue, depressed tooth and pain, and fracture of the restoration. In this case, the patient with multiple tooth abrasion and clenching habit, the edentulous maxillary area is restored with amalgam inserted RPD, and the dentulous area of the maxilla and mandible are treated with fixed restoration accompanying with the increase of vertical dimension. Consequently, we are going to report about the satisfying result in both functional and esthetic aspects.

'Luckyone 2ho' is a new orchardgrass (Dactylis glomerata L.) cultivar developed by the National Institue of Animal Science (NIAS) in 2017. To develope the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. The agronomic growth characteristics and forage productivity of 'Luckyone 2ho' were examined at Cheonan from 2012 to 2014, and regional trials were conducted in Cheonan, Pheonchang, Jinju and Jeju from 2015 to 2017, respectively. 'Luckyone 2ho' showed medium type growth habit in fall, and medium in length of flag leaf and very long upper internode. Plant height of 'Luckyone 2ho' was 3 cm less than that of standard cultivar, 'Potomac' and heading date was 1 days later than 5th May compared to standard cultivar, 'Potomac'. Characteristics such as waterlogging and disease resistance of 'Luckyone 2ho' were stronger or better than those of standard cultivar, 'Potomac', Especially, dry matter yield of 'Luckyone 2ho'(15,980 kg/ha) increased 9 % compared to that of standard cultivar, 'Potomac'(14,702 kg/ha). Nutritive values were appeared to be similar in both varieties except in Vitro dry matter digestibility(IVDMD) and crude protein and total digestible nutrients (TDN).

The purpose of this study is to reveal the process of enactment and revision, the contents of the police uniform system by the Government-General of Joseon, and to examine the relationship between the uniform system and the ruling policies of Imperialist Japan. The research methodology involved document research of official gazettes that published legislation on the police uniform system. Political background was referenced from various preceding studies. The research results are as follows. The Japanese invasion of Korea, in regards to the police, appeared as infiltrations through the three routes of consular police, temporary military police, and inside the Korean police. Each organization had different uniform systems, and after the installation of the Japanese police in 1907, the uniform system of high level officers of the Korea police was changed to the Japanese-style. After the installation of the Government-General of Joseon in 1910, a police uniform system was not enacted until 1918, with the exception being made for police officers due to the military police system. The 'Police Officer Uniform System of the Government-General of Joseon' enacted in 1918 stood out for its golden insignia on solidly colored fabric, which effectively indicated rank, as well as the Japanese flag pattern and the cherry blossom pattern, which symbolized imperialist Japan, on the cap badge and insignia. The 1918 uniform system had many differences from the Japanese system of the time in terms of design, perhaps due to the political autonomy of the governor-general. The 1918 uniform system was completely revised in 1932. This uniform system was modified in various ways. The system was almost identical to the Japanese system at that time. This is the result of Japan's intent to dominate Korea, which involved assimilating Korea into Japan with the purpose of conducting a full-fledged invasion of the continent after the Manchurian Incident.

Under the flag of creative economy, Korea government is now releasing public data in order to develop or provide a range of services. In this paper, we develop a customized trip navigation system to recommend a trip itinerary based on integration of open government data and personal tourist data. The system uses case-based reasoning (CBR) to provide a personalized trip navigation service. The main difference between existing trip information systems and ours is that our system can offers a user-oriented information service. In addition, our system supports Turn-key style contents provision to maximize convenience. Our system can be a good example of the way in which open government data can be used to design a new service.

Through the Broadcasting Act, Republic of Korea regulates the broadcasting system to remain neutral regarding particular party or candidate. However, as MBC and JTBC reports the issue of President Park's impeachment in bisected way - conservative and progressive - the controversy aroused. This research paper comparatively analyzed each broadcasting company's evening news by focusing on quantity aspect, reporting tendency regarding trend of public opinion and mass rally and the news frame. Our research showed that both JTBC and MBC had partially reported; JTBC on pro-impeachment rally's side which was called candlelight rally, and MBC on anti-impeachment rally's side, called Korean National Flag rally. Regarding the way how they reported the impeachment, JTBC reported much more in depth than MBC, and MBC reported the process emotionally, standing for President Park.

The objective of this study is to consider the uniform as visual communication, and analyze the expression of symbol shown on the uniform design by the pattern by applying the visual symbol in the communication and operation of the meaning. Also, it is to construct the systematic modeling method of the expression of design symbol by the pattern of uniform in th e various fields. This study is to analyze the symbolic expression method of the uniform design by the pattern by suggesting the symbolic expression method as a frame through the visual symbolic approach of the uniform design and the analysis of semantic symbol according to that. As a result, there arose simplification and emphasis and a method of symbolic expression with the national flag, a conceptual factor characteristically in the sports uniform design. The characteristics of symbolic expression of uniform design were mainly used in the symbolic expression with the customary code and symbol. Also, the uniform in the enterprises were widely used in the expression of uniform with the suggestion and code by the color. As for the characteristics of symbolic expression shown on the event uniform design, the method of symbolic expression by the pattern of uniform was grasped differently asa result of symbolic expression through the image. The method of symbolic expression suggested on this study could be used on a basis of uniform design in the future. Accordingly, this study has a meaning of suggesting the methodology of uniform design that would be a parameter.

The Passenger Service Equipment(PSE) provide various train operation data such as flag station data. When PSE incur service failures or errors, passengers who use the train feel great inconvenience. In this paper, I have chosen PSE that were important to passengers and have applied Reliability Centered Maintenance(RCM), deviating from the existing perspective that operators have taken to perform RCM. FMEA/FMECA was performed for reliability analysis of the PSE. The highly critical device among the PSE is defined as the Passenger Information Control System(PICS), which is used to control the automatic announcement and signaling board. Through Weibull distribution of the PICS, failure analysis was performed. Based on the analyzed results, I have proposed a solution that will minimize service failure of PICS.
