In this paper, we describe research results of developing hardware rasterizer that is applicable to mobile 3D graphics system, designed in SIMD architecture and verified in FPGA. Tile-based scan conversion unit is designed like SIMD architecture running four tiles simultaneously and each tile traverses pixels hierarchical in 3-level so that visiting counts is minimized. As experimental results, $8{\times}8$ is the most efficient size of tile and the last step of tile traversing is performed on $2{\times}2$ sized subtile. The rasterizer supports flat shading and gouraud shading and texture mapper supports affine mapping and perspective corrected mapping. Also, texture mapper supports point sampling mode and bilinear interpolating sampling mode and two types of wrapping modes and various blending modes. The rasterzer operates as 120Mhz on xilinx vertex4 $l{\times}100$ device. To easy verification, texture memory and frame buffer are generated as block rom and block ram.

The vitality of the city's commercial district, which in the base of city life and provides vitality and diversity of life, has a great impact on the vitality of the entire city and the revitalization of the local economy. The revitalization of the commercial street is related to the activation of walking, and walking is closely related to the quality of life because it involves a wide range of interactions with the surrounding environment beyond simple movement. This quality of life leads to 'Livability'. In order to revitalize pedestrians on the commercial street, the liberty factor was derived and the importance of what was the most important and effective for the activation of the commercial street was analyzed. As a result, it was found that the items representing the atmosphere and purpose, which are detailed indicators of placeness, had a high priority, and it was found that the detailed indicators belonging to accessibility came out with a lower priority. In order to increase the livability of the commercial street, the priority is to increase the spatiality of the space, and if pedestrians are activated as the number of visits and stay time of visitors increases, it can be extended to the vitality of the entire area.

Related institutions that use radiation are diverse in Korea, such as research, medical care, and education. Recently, the number of examinations and visits to medical institutions is increasing. As a result, the number of radiological examinations in medical institutions is increasing. Radiation safety management is necessary as well as exposure of radiation workers. For safety management, first of all, it is necessary to wear the personal exposure dosimeter correctly and measure it accurately after wearing it. This study tries to evaluate and verify the measurement straightness of PLD devices by radiation of a diagnostic generator. Radiation division irradiation time interval was measured after irradiating 10 times at 10, 30, and 60 sec and irradiating the irradiation distance from 30 to 100 cm at 10 cm intervals to measure the change in absorbed dose depending on the distance. As a result, there was no difference in absorbed dose by time interval. This is considered to be helpful in various studies by using a diagnostic generator for the study of high absorbed dose.

Unlike previous studies, which mainly analyzed factors affecting tourism motivation and tourism satisfaction, this study analyzes the political, economic and cultural factors affecting the number of Chinese tourists visiting Korea. Empirical results show that political factors such as the Chinese regime, the number of meetings and talks between Korea and China, the number of phone calls between the two countries, and the Korea-China FTA (also as a economic factor) have a significant impact on the number of Chinese tourists visiting Korea. In particular, political friendly variables related to economy (ex. Korea-China FTA) has been analyzed to have a more significant positive effect on the number of Chinese tourists to Korea than the factors that create friendly atmosphere only in the political field. In addition to political factors, economic factors such as the Korea-China FTA, and cultural factors such as Korean Wave represented by Korean cosmetics also have a significant impact on the number of Chinese tourists visiting Korea.

During the industrialization and urbanization of the country, urban rivers have been covered over and developed without forethought and thus became estranged from spaces utilized by area residents in everyday life. Recently, an influx of people and uses have increased largely because accessibility improved through restoration projects which have transformed these river areas into pleasant environments. It thus appears that these projects have an impact on community consciousness for area residents who live near the restored rivers to some extent. The purpose of this study was to determine via questionnaire the effects and influences of urban river restoration on area residents targeting visitors to Seongnaecheon(stream), Songpa-gu, Seoul, which has been restored recently. Factors in the questionnaire analysis included such items as the use status of Seongnaecheon, community consciousness(feeling of belonging, solidarity, feeling settled), and a before and after comparison of the restoration(change of consciousness, regional effects), etc. According to the results of analysis, visitors who have utilized the stream more than 1~2 times per week after the restoration project accounted for the greatest portion. The main purposes of these visits were to 'rest' and 'exercise' while the ratio of using it as a 'meeting space with neighbors and strangers' was low. Community consciousness of area residents using Seongnaecheon was generally high. As a result of an analysis of consciousness differences between groups after dividing visitors into 3 groups according to the frequency of visits, there were significant differences in the consciousness level between groups with high community consciousness levels in visitors who visited frequently. In consideration of these results, the provision of programs along with proper facilities that can be used is deemed important for area residents so as to inspire community consciousness of the area by means of activating both community activities and the progressive use of the restored river.

This study was conducted to identify the diabetes self-care (DSM) knowledge, DSM competence, DSM behavior, and quality of life according to HbA1c control in diabetic elderly. The participants were 205 diabetes elderly who visited the citizen health promotion center located in D city, Korea. Data were collected from April, 4 to August 31 2015, and were analyzed by the t-test and chi-squared test using IBM SPSS 23.0. The mean scores of DSM knowledge, DSM competence, DSM behavior and quality of life were $50.61{\pm}16.39$, $71.27{\pm}10.21$, $62.78{\pm}1.29$ and $0.86{\pm}0.11$, respectively. Additionally, DSM behavior (t=2.17, p=0.031), education level (t=11.80, p=0.0019) l, BMI (t=0.001, p=0.012), and number of visits to citizen health center (t=16.497, p=0.001) differed significantly between the controlled HbA1c group and uncontrolled HbA1C group. However, ANCOVA revealed that the level of HbA1c did not affect the DSM behaviors. Therefore, it is necessary to develop and apply a DSM education program that reflects the characteristics knowledge level of the elderly. In addition, healthcare institutions with high accessibility in terms of distance and cost to guide and manage desirable diabetic self-care behaviors should be provided everywhere.
