The Goals of Intelligent Network(IN) provide the methods that create, test and apply the various hinds of services to satisfy the user's need. In this environments, we can create new IN service by description of GSL(Global Service Logic) using that SCE(Service Creation Environment). In the ITU-T CS-2, the various SIBs(Service Independent Building-blocks) are defined to develop the services. There are limitations to develop the various services using the SIBs defined in recommendation. So, in this paper, we define the new SIBs and implement the SCE. The new SIBs are defined in this paper are Connect SIB and BCSM Event SIB. The Connect Call SIB provides the connectivity between SLPI(Service Logic processing Program Instance) and call after connecting the calling party to called party. The BCSMEvent SIB provides the functions that request SSF to report the call processing event and receive it. In this paper, we design and implement the SCE that supports the SIBs defined by recommendation and this paper, provides GUI environment to specify GSI, and generates the code used by SCP.

Effective alerts will drastically mitigate the disaster impacts. One way to enhance the effectiveness is to prepare multiple alert distribution channels. In this paper, we propose a new emergency alert distribution system that will solve the weaknesses of the current distribution systems, such as Cell Broadcasting System and T-DMB Automatic Emergency Alert Service. The weaknesses are: the limitation of message length, small portions of terminals that can receive and display the alert signal, and one-way communication service. To solve these problems, we propose an emergency alert distribution system over the Internet with RSS (Rich Site Summary) format. The system also has the capability of adaptive alert filtering according to the receiver characteristics. We analyzed the characteristics of RSS as an alerting format, and draw functional requirements satisfying use case scenarios. We designed the system only with major requirements and verified it on our test bed. Sending richer message contents through various receiving terminals, the system will achieve more effective emergency alert service.

This is an underlying study for expanding child growth and developmental screening program, which had been implemented as a part of maternal child health service in a certain public health center located in P City. This study attempted to develop system model to discover, consult and follow-up developmental disabilities in children in early stage. For the purpose of providing groundwork for further development of screening program, the system model was analyzed and evaluated. One of the focuses of this study was developing practical tool that can aid small number staffs of public health center to handle large number of patients. 9 types of developmental checklist by key month was developed to support understaffed public health center. These checklists were also supplied to other public health centers, greatly improving qualitative and quantitative development of screening project. Also, the 4-step program of operating and managing child growth and developmental screening was proved to be quite effective. Total 632 children were evaluated and 21 of them were suspected to have developmental problem. Among these children, 8 children were determined to receive regular supervision of public health center. Other 13 children were recommended to visit professional institution, but only 7 of them actually visited institution. Four of these children who visited professional institution are currently receiving treatment, while the other 3 children were determined to require close observation. Five times of screening education were provided to the staffs in public health center and personnel in charge of children in every district public center in P City. The purpose of this training was to improve individuals' capability to implement project and to establish basis for expanding child growth and developmental screening program. The participants were guided to have continuous attention for the project, and their knowledge, skill and recognition were greatly improved through educational training. Also, professional child consulting and education, including lecture for baby food and baby food menu exhibition, were given to parents. Through this opportunity, parents acquired higher understanding about baby food while the local residents' recognition for maternal child health service was greatly improved.

Lookism is spread largely because many people think beautiful people are treated better and receive more favors. This trend has been influenced by mass media and impacted by commercial marketing strategy. The expectation for the beauty have risen higher than ever. People expect beautiful body and beautiful face which are more difficult to meet the standard of beauty. People desire tall and skinny body. The purpuse of this study was to find out body image from college females in the age which they are very sensitive to appearance. This research focused to find out how they perceived their own body shape and their perception of the most ideal body shape. Measuring tool for the research was 9 pictures of body silhouette from very skinny to very fat. To analyse the respondents' objective body image, Body Mass Index were employed. The result of this research indicated that there were distinct differences between their subjective body images and ideal body images. This result indicated that they were not satisfied with their own body shape and hence they were not confident towards their body images. Even though their objective bodies were normal or under weight, they still felt they were over weight. This meant their body images were misrepresented. They preferred thinner bodies even though their bodies were perfectly normal and healthy. But these misrepresented body images could be unhealthy physically, psychologically, or socially. These results showed that college females were overly obsessive with superficial appearance rather than improving ones capability to be more competitive in the society. From this research, I tried to find out perception of body image and it's distortion which was debated a lot in our society. I also want to provide basic reference material for establishing the body image study.

Radar remote sensing is appropriate for rice monitoring because the areas where this crop is cultivated are often cloudy and rainy. Especially, Synthetic Aperture Radar (SAR) can acquire remote sensing information with a high temporal resolution in tropical and subtropical regions due to its all-weather capability. This paper analyzes the relationships between backscattering coefficients of rice measured by RADARSAT-2 SAR and growth parameters during a rice growth period. And we applied the relationships to crop monitoring of paddy rice in North Korea. As a result, plant height and Leaf Area Index (LAI) increased until Day Of Year (DOY) 234 and then decreased, while fresh weight and dry weight increased until DOY 253. Correlation coefficients revealed that Horizontal transmit and Horizontal receive polarization (HH)-polarization backscattering coefficients were correlated highly with plant height (r=0.95), fresh weight (r=0.92), vegetation water content (r=0.91), LAI (r=0.90), and dry weight (r=0.89). Based on the observed relationships between backscattering coefficients and variables of cultivation, prediction equations were developed using the HH-polarization backscattering coefficients. Concerning the evaluation for the applicability of the LAI distribution from RADARSAT-2, the LAI statistic was evaluated in comparison with LAI distribution from RapidEye image. And LAI distributions in Pyongyang were presented to show spatial variability for unaccessible areas.

The important issues of facility database management in GIS are to collect up-to-date information and to update information in accordance with new-establishment, repair and replacement of the facilities. Therefore, it is necessary to develop a system which has capability of monitoring facilities as well as managing database efficiently. The purpose of this study is to propose possibility of implementation of mobile GIS solution for the facility management. In order to achieve the goal, to process existing digital maps and to receive on-site information through the wireless communication service are required. In addition, the system is required to process spatial information obtained by GPS and digital photogrammetric technique with real-time updating database in server. The system increases efficiency both in work flow and monitoring for facility management by providing optimal routing information to the sites and real-time two-way communication using VoIP(Voice over Internet Protocol). The system is expected to perform real-time database management effectively. In consequence, the system could appropriately response on-site situations in various practical applications. The proposed technology could contribute to improve nation's leading-edge technology.

Purpose - This paper aims to articulate relationship about factors influencing FTA utilization by dividing them into company's external and internal factors and performing investigation on the relationship between FTA utilization and export performance. Design/methodology - This study verified factors influencing FTA utilization by dividing them into company's external and internal factors and performing investigation on the relationship between FTA utilization and export performance. Empirical analysis was performed by setting internal and external factors required for FTA utilization as variables. To achieve this, research model was established based on previous study, hypothesis was deduced, and statistical program were used to test the hypothesis. This study performed empirical analysis using statistical program of SPSS 18.0 and AMOS 18.0 for the research model. Findings - Empirical analysis was performed regarding the effect of the FTA utilization on export performance and previous study defined export performance as the company's increased economy benefits through export and increase in new transactions. Analysis was also performed for factors affecting the FTA utilization by the company and through management and response of external factors and internal factors it was confirmed that the FTA utilization by the company led to increase in the company's export performance as a result. This study proposes a method to achieve export performance based on this. Originality/value - Companies seeking to utilize the FTA sign the Contract for the International Sale of goods and there are many conditions to meet in order to receive trade preferences during the transaction process. Existing trade order and order in the FTA have to be followed. Country of origin can be seen as key in the FTA. The Rule of Origin becomes the most important evaluation standard in applying preferential tariff in the FTA. Such regulations can be seen as external factors which cannot be controlled by the company. Internal factors are capabilities owned before that can be controlled by the company. The study sought to test the variables regarding factors centered on such capability. This study verified factors influencing FTA utilization by dividing them into company's external and internal factors and performing investigation on the relationship between FTA utilization and export performance.

Background: The Life-Sustaining Treatment Decision-Making Act has allowed anyone aged 19 or older to sign an Advance Directive not to receive life-sustaining treatment when they are in the 'death process'. Recently, the Korean Pharmaceutical Association announced to raise awareness of the Advance Directive to the general public through community pharmacies across the country. This study aimed to investigate the public's willingness to accept pharmacist's consultation regarding the Advance Directive and to present future directions to pharmacists Methods: This cross-sectional questionnaire study using 16-items was conducted in adults, Study subjects were recruited by convenience sampling method during August 5-15, 2020. Results: Of 460 respondents, 51.7% were younger than 30-year-old and 58.7% were not in the healthcare field in terms of job or major. 60.2% knew about the Advance Directive and 81.7% agreed the necessity to sign when healthy. 50.0% had the willingness to consult with pharmacists on the Advance Directive for well-dying and 80.4% preferred verbal explanation together with written information. Simple linear regression analysis results showed a significant relationship between trust in pharmacists or satisfaction with pharmacist's communication and willingness to use pharmacist' consultation on the Advance Directive (1-point increases in values measured on a five-point scale are associated with 0.464 and 0.486 increases, respectively.) Conclusion: This study suggests that pharmacists need to improve the public's trust and communication capability to satisfy with public's demands on well-dying service.
