The advertisement is an informative product in which a company or an organization has made a substantial capital investment in order to achieve their goals based on their carefully thought-out plans. David Ogilvy maintaned that making a headline of an advertisement is worth 80 percent completion of the advertisement. As he insisted, a headline is also the most important element in the printing advertisement. Therefore, the importance of selecting headline's font style is increased because, while creating a headline, it is necessary to consider the emotional aspects of the advertising object that attract the attention of people. Many researchers call 'typography' as 'frozen sound' or 'written sound' because typography not only works as a letter but also provide people with an emotional pleasure. An appropriate selection of headline's font style in the advertisement production makes both the client and the audience for the advertisement satisfied because it reduces the communication risk and makes design results more reasonable. It is difficult to find many decision-making methods for selecting headline's font style. Therefore, the author of this paper investigated the trend of the use of headline's font style in order to help the designer understand headline's font style as one of design factors. As a result of the research, it is possible to conclude that, while selecting the headline's font style, the attributes of a font consist of limited style, and more objective and systematic font selection methods are necessary.

We investigate the Japan's Master Plan of Comprehensive Sewerage System (JMPS) and Lake Biwa basin sewerage and suggest future development direction of the Watershed Sewerage System Maintenance Plan in Korea enforced on February 2, 2013. The JMPS is designed for compliance with the environmental standard for water quality under the Environmental Policy Act. The effluent standards applied in the master plan of Lake Biwa's Sewerage Plan for the Lake Biwa is tougher than the national standards. Therefore the Lake Biwa Baisn Sewerage System was the first in Japan to adopt facilities that perform advanced treatment for nitrogen and phosphorus removal. BOD, SS, T-N and T-P concentrations of discharge water of sewage are 0.9, 0.6, 5.5, 0.06 mg/L, respectively. Especially removal efficiency for BOD is 99.5 percent. It is necessary to study the diversification of the evaluation criteria, cost minimization approach, subsidy system improvement, economic concept of discharge load adjustment system and establishment of basin sewerage concept for the development of the basin sewerage plan in Korea.

In this study, we analyze the community health survey data for 3 years from 2011 to 2013 were analyzed for evaluation. This study attempts to comprehensively evaluate differences between elderly medical aid beneficiaries and elderly health insurance beneficiaries in terms of health-related quality of life, All of elderly medical aid beneficiaries who responded community health survey were included for study and elderly health insurance beneficiaries were randomly selected as a control group by matching gender, age and location. The findings show that the elderly medical aid beneficiaries can not receive sufficient health care services, even though they have pay a low socio-economic status, spouse or fewer households enemies and poorer health behavior and higher morbidity of chronic diseases than the elderly health insurance beneficiaries do. But elderly health insurance beneficiaries also showed that not enough care utilization is high morbidity of chronic diseases. These factors aggravate the medical aid beneficiaries' health-related quality of life This characteristic was analyzed to lower health-related quality of life of the elderly. Therefore, it is necessary to strive for the development of appropriate services and programs taking into account the characteristics of the elderly that may go though a limited resource and promote the quality of life for the elderly more effectively re-evaluation of social services systems and programs related to elderly.

Purpose: In radiation therapy, precise calculation of dose toward malignant tumors or normal tissue would be a critical factor in determining whether the treatment would be successful. The Radiation Treatment Planning (RTP) system is one of most effective methods to make it effective to the correction of dose due to CT number through converting linear attenuation coefficient to density of the inhomogeneous tissue by means of CT based reconstruction. Materials and Methods: In this study, we carried out the measurement of CT number and calculation of mass density by using RTP system and the homemade inhomogeneous tissue Phantom and the values were obtained with reference to water. Moreover, we intended to investigate the effectiveness and accuracy for the correction of inhomogeneous tissue by the CT number through comparing the measured dose (nC) and calculated dose (Percentage Depth Dose, PDD) used CT image during radiation exposure with RTP. Results: The difference in mass density between the calculated tissue equivalent material and the true value was ranged from $0.005g/cm^3\;to\;0.069g/cm^3$. A relative error between PDD of RTP and calculated dose obtained by radiation therapy of machine ranged from -2.8 to +1.06%(effective range within 3%). Conclusion: In conclusion, we confirmed the effectiveness of correction for the inhomogeneous tissues through CT images. These results would be one of good information on the basic outline of Quality Assurance (QA) in RTP system.

This paper aims to understand the conceptual definition and the characteristics of reality shock in new graduate nurses. We analyzed the data using the hybrid model, initially introduced by Schwartz-Barcott and Kim. The data used in this study were collected from six recently graduated nurses who work in S-si and G-si. Another part of the data was obtained from literature review regarding Reality Shock. We categorized Reality Shocks in recently graduated nurses into nine attributes within a three-dimension model. The dimensions include "cognitive", "emotional", and "situational" domains. The cognitive domain is to be aware of the factor that causes Reality Shock. The emotional domain is the negative emotional responses that appear when facing a situation causing Reality Shock. The situational domain is the sort of circumstantial situations that cause Reality Shock. Reality Shock is defined as recently graduated nurses having several negative emotions, such as powerlessness, difficulty in peer relationships, confusion, and pressure due to (i) the differences between reality of nursing and what they have learned in school, (ii) the differences between an ideal situation and the real situation, (iii) the lack of expertise of senior nurses, (iv) a situation without the respect from colleagues, and (v) the overloaded role compare with the expectations. In conclusion, we provide a guideline for establishing a strategy to reduce Reality Shock in recently graduated nurses by identifying the concept of Reality Shock.

It is very challenging to analyze the traffic flow in the city because there are lots of traffic accidents, intersections, and pedestrians etc. Now, even in mid-size cities Bus Information Systems(BIS) have been deployed, which have offered the forecast of arriving times at the stations to passengers. BIS also provides more informations such as the current locations, departure-arrival times of buses. In this paper, we perform the time-series analysis of the traffic flow using the data of the average trvel time and the average speed between stations extracted from the BIS. In the mid size cities, the data from BIS will have a important role on prediction and analysis of the traffic flow. We used the Dynamic Linear Model(DLM) for how to make the time series forecasting model to analyze and predict the average speeds at the given locations, which seem to show the representative of traffics in the city. Especially, we analysis travel times for weekdays and weekends separately. We think this study can help forecast the traffic jams, congestion areas and more accurate arrival times of buses.

A multi-attribute utility analysis was investigated as a tool for the decision support of countermeasures in early phase of a nuclear accident. The utility function of attributes was assumed to be the second order polynomial expressions, and the weighting constant of attributes was determined using a swing weighting method. Because the main objective of this study focuses on the applicability of a multi-attribute utility analysis as a tool for the decision support of countermeasures in early phase of a nuclear accident, less quantifiable attributes were not included due to lack of information. In postulated accidental scenarios for the application of the designed methodology, the variation of the numerical values of total utility for the considered actions, e.g. sheltering, evacuation and no action, was investigated according to the variation of attributes. As a result, it was shown that the numerical values of total utility for the actions are distinctly different depending on the exposure dose and monetary value of dose. As increasing in both attributes, the rank of the numerical values of total utility increased for evacuation, which is more extreme action than for sheltering, while that of no action decreased. As expected probability of high dose is higher, the break-even values for the monetary value of dose, which are the monetary value of dose when the ranking of actions is changed, were lower. In audition, as aversion psychology for dose is higher, the break-even values for dose were lower.

Although rural areas account for more than 80% of the total land area of South Korea, most of them are deteriorated and living environment is inconvenient. In addition, the migration of young generation to urban areas and ageing have reduced the population and caused not only cavitation phenomena of villages but also stagnant communities. As for one of the rural areas, the seat of Myeon Office located in Oesan-myeon, Buyeo-gun, Chungcheongnam-do, this study presented not a plan only for strengthening hub functions but the methodology of the complex development plan in consideration of the regional characteristics in the comprehensive improvement project in seat of Myeon Office. From the perspective of enhancing the function of the seat of Myeon Office, it is inevitable to establish plans based on hardware. However, empowerment of the residents in the targeted areas also works as an important factor. In other words, each project promoted by the plan will be mainly operated by the local residents. Therefore, it is necessary to establish a management system of this. The success or failure of the established plan is based on the accurate survey of the issues of the targeted areas and demand, and this depends on participation and positive response of the residents of the targeted areas. That is, the method as a 'local community network' is required in order to increase the effect of resident participation in the planning area.

Versatile Video Coding (VVC), a next-generation video coding standard that is in the final stage of standardization, has adopted various techniques to achieve more than twice the compression performance of HEVC (High-Efficiency Video Coding). VVC adopted Bi-prediction with CU-level Weight (BCW), which generates the final prediction signal with the weighted combination of bi-predictions with various weights, to enhance the performance of the bi-predictive inter prediction. The syntax element of the BCW index is adaptively coded according to the value of NoBackwardPredFlag which indicates if there is no future picture in the display order among the reference pictures. Such syntax structure for signaling the BCW index could violate the flexibility of video codec and cause the dependency issue at the stage of bitstream parsing. To address these issues, this paper proposes an efficient BCW weight signaling method which enables all weights and parsing without any condition check. The performance of the proposed method was evaluated with various weight searching methods in the encoder. The experimental results show that the proposed method gives negligible BD-rate losses and minor gains for 3 weights searching and 5 weights searching, respectively, while resolving the issues.
