Recently, spread of large amount Smartphones made users to download location-based service applications, which provided by application developers. These location-based service applications are convenient tool for users. Location-based service use technology to find location of user and provide information of user's location. Leakage of information of user's location and expose of privacy life raised new controversy. In this thesis, it will analyze relations of increase of Smartphone market, usage of Location-based service and severity of personal information leakage. Also, it will analyze examples of user's case of damage which caused by leakage personal information and find solutions to reduce damage of personal information leakage. In research, it will find cases of damage that cause by Location-based service. Also it will analyze and research cases of damage and present with graph and chart. In conclusion, to reduce and prevent from damage which caused by leakage personal information, it is important that users and application developers to realize danger of private and personal information leakage. Also, user's personal information must deal with cautiously and application developers have to research and develop the application with powerful security.

This study aims at establishing master plan for efficient establishment of comprehensive drought management information system as non-structural drought counterplan which provides drought damage in advance. Domestic and abroad research related to drought were surveyed and analyzed through many literature and internet for systematic drought management information system. Long-term master plan for comprehensive drought management information system is divided into 3 steps. In first step, drought monitoring system including development of hydrological drought assessment index, drought outlook analysis method and GIS web based drought monitering system is established. In second step, water supply plan and guideline through water shortage danger assessment by areal characteristics is established. In third step, comprehensive management information system through export system linked to KORSIM and establishment of information shared system between each bureau related to drought. Based on this study, master plan for efficient development and application of drought management information system is proposed, it is expected to be applied as guideline for second and third step of drought management information system.

The technology of Computer Graphics (CG) has been in great progress for almost 20 years and has proven to be a valuable tool for a broad variety of fields, including nuclear engineering. To work in any hazardous environment for example radiation field is particularly challenging because the danger is not always visually apparent. In this study as the application of CG to nuclear engineering field, we proposed to develop a radiation risk recognition aided system in which various radiation information; radiation risks, radiation distribution, hazard information and so on, were visualized by CG. The system used the server and client system. In the server there were two parts; one (main-server) was the database part having various data and the other (sub-server) was the visualization part visualizing the human phantom by POV-Ray. In the client there was the input and output part. The outputs from the system were various radiation information represented by coloring, circle graph and line graph intuitionally. The system is useful for a broad range of activities including radiation protection, radiation management, dose minimization, and demonstration to the public.

최근 지구 온난화 등의 이유로 국지성 집중 호우가 빈번히 발생함에 따라 도로의 침수로 인한 피해가 증가하고 있지만, 그에 따른 예방책은 미비한 실정이다. 이에 본 연구에서는 도로 침수로 인해 발생할 수 있는 차량 침수나 교통 체증 등의 피해를 방지하도록 운전자에게 사전에 알려줄 수 있는 침수 위험정보 표출 시스템을 설계하고자 한다. 본 시스템은 C# 기반으로 ArcObject API를 활용하여 사용자가 도로별 침수 위험 정도를 쉽게 파악할 수 있도록 GUI 환경으로 구성되어 있다. 제안된 방법을 활용하면 사용자들이 현재 자신이 있는 지역이 침수에 대해 얼마나 위험한지를 침수위험정보를 통해 알 수 있다.

This study measured the effects of fake news and propaganda on managing information on COVID-19 among the Nigerian citizenry. This study examined sources of information on COVID-19 available to the people, evaluated reasons behind spreading fake news, examined how fake news has affected the spread of COVID-19 pandemic in Nigeria, established the consequences of fake news on managing COVID-19 pandemic and as well identified ways to contain fake news at a time like this in Nigeria.It is a survey with a sample size of 375 participants selected using simple random technique. Instrument of data gathering was questionnaire widely distributed in the six geo-political zones of Nigeria using Survey monkey. Data was analysed using frequencies, counts and percentages, tables and charts. Findings revealed that people rely more on radio, television, and social media for information on COVID-19. Fake news is spread by people mostly for political reasons and intention to cause panic. In Nigeria, fake news has led to disbelief of the existence of the virus thereby leading to violation of precautionary measures among the citizenry and lack of trust in the government. Concerted effort on the part of the government is required to give public enlightenment on the danger of fake news. Also, directorate of anti-fake news should be established to censor and reprimand sources of fake news. People should always check source of information to confirm its credibility and be weary of sharing unconfirmed information especially on the social media.

With the increasing danger of personal information being exposed, a technique to protect personal information by identifying a non-user in case it is exposed. A study to construct a neural network recognizer for developing a economical and effective user protecting system. For this, time variables regarding user typing patterns from a pattern extraction device. With the variations in the standard deviation for the collected time variables, non-user patterns were generated. The recognition performance increased with the increase in the standard deviation and a higher recognition was achieved at 2.5. Also, five types of training data were generated and the recognition performance was examined as a function of the number of non-user patterns. With the increase in non-suer patterns, the recognition error quantified in the root mean square error (RMSE) was reduced. The smallest RMSE was obtained at the type 5 and 90 non-user patterns. In overall, the type 3 model yielded the highest recognition accuracy Particularly, a perfect recognition of 100% was achieved at 45 non-user patterns.

Alexander the Great was a world-class leader with tremendous courage. He paid no heed to the dangers of the battlefield, so he was always in the front lines. However, his excessive courage put his life in danger. Herein, we present an analysis of the information contained in the chronicles about a very severe, life-threatening thoracic trauma that nearly killed the great stratelates. The detailed descriptions made by Arrianus allow us to conclude that Alexander the Great experienced a nearly fatal case of tension pneumothorax. Information on how he was managed is also presented.
