Gastric cancer has been consistently decreasing worldwide, whereas cardia gastric cancer is on the rise. This indicates that the exposure rates to epidemiological causes are changing. In this study, we aim to review the risk factors for gastric cancer with respect to cardia and non-cardia types. One of the most significant risk factors for gastric cancer is Helicobacter pylori infection. H. pylori infection is known as a risk factor for non-cardia gastric cancer, and there have been results indicating that H. pylori infection is not associated with cardia gastric cancer. However, in the East Asian region, there is epidemiological evidence suggesting that H. pylori infection might be a risk factor for cardia gastric cancer. Smoking and alcohol consumption are known risk factors for gastric cancer, regardless of anatomical location. Obesity is considered a factor in the development of cardia gastric cancer. However, further research is needed to understand the specific relationship with non-cardia gastric cancer. The consumption of high-salt and processed meat is more distinctly associated with noncardia gastric cancer than in cardia gastric cancer. In addition to these factors, exposure to chemicals and radiation are considered risk factors for gastric cancer. Primary prevention of gastric cancer involves eliminating or avoiding risk factors such as H. pylori eradication and adopting a healthy lifestyle, including quitting smoking, reducing alcohol consumption, maintaining a healthy weight, and having a low-salt diet.

There are certain guidelines on the channel design such as domestic guidelines（Korean and japanese, etc.）and international guideline known as PIANC Rules（Permanent International Association of Navigation Congresses Rules）, in the world These rules have considered many factors such as natural conditions, ship maneuverability and geographical features etc. But it is contented toot the area of these rules toot are meant to facilitate the ease of ship-handling is insufficient. To satisfy this point in design process, it is necessary to take into account the difficulties encountered in ship-handling within these inland waterways. Because many vessels are navigating at the same time within these waterways, the specific navigable traffic volume should be considered with regard to the standard process of route designing. It must also be considered with regard to the volume of navigable traffic bemuse of ship-handling difficulty toot arises within the same waterway with varying amounts of traffic volume because toot ship-handling/manueverability is directly influenced by these factors. This paper aims to propose a new approach to the design of standard inland water route considering the traffic volume and the shape of waterway. Also consider the relationship among these factors may affect to the ship-handling difficulties.

When firms are confronted with IT investment decision-makings, technical or financial factors are widely considered. However, based on sociotechnical systems theory, it is argued that in addition to the traditional factors, social issues must be considered in the IT investment decision-makings. Even though the strategic criteria of social issues within organization are important for IT investment decision-makings, the social or organizational issues are hardly considered in IT implementation and adoption(Ryan and Harrison, 2000). The objective of this study is to empirically verify how the comprehensive consideration of both of technical and organizational issues related with IT investment affects firm performance through its impact on IT technical capability and IT personnel skills. Senior managers of 153 Korean firms were surveyed, and the collected data were analyzed with PLS technique. The results of the PLS path analysis show that the comprehensive consideration of the technical and social issues affected indirectly firm performance through IT technical capability and IT personnel skills. It is found that the comprehensive consideration had a significant impact on IT technical capability and IT personnel skills, and that IT technical capability and IT personnel skills affected firm performance. IT personnel was also found to affect IT technical capability. Finally, this study found that the consideration of social factors had greater impacts on firm performance than that of technical factors.

The objective of this research is significant because it derives the core competency factors that members of education communities must have in order to form warm education communities through investigating the perception of special education teachers. To achieve this, 352 special education teachers and teachers working at special education institutes were asked to record three of the most important factors out of a total of 18 factors that members of an educational community considered to be required in order to form warm educational communities. IBM SPSS Statistics 23 was used to analyze the collected data. First, in oder to examine the demographic characteristics of the educators surveyed, frequency analysis was conducted. Second, frequency analysis on the factors that special education teachers considered to be most important to form a warm education communities was conducted by teacher experience and type of education institute they worked for. When analyzing the research results of main factors that special education teachers considered to be important by teacher experience and type of education institute they worked for, responsibility was confirmed to be the most important factor. The second most important factor was communication and the third most important factor was responsibility and trust. In summary, the research confirmed that if mutual trust between the members of an education community can be established and if problems can be solved through cooperation and through open communication, and if each member of the community serves their role responsibly, a warm education community can be formed.

This study is aimed at considering the relationship between the influential factor in Smartphone purchase and consumer awareness. For this purpose, this study set up the influential factors in Smartphone purchase as advertising effect, brand effect and usability effect and corporate image effect, and considered the relationship between these influential factors and consumer awareness empirically. The research results can be summarized as following 3 parts: First, the four factors suggested as the influential factor in Smartphone purchase were verified to have a significant influence on customer satisfaction and customer loyalty, and thus, it is thought that the bigger the influence of these factors, the more customer satisfaction and customer loyalty will increase. Second, among the factors suggested as influential factors in Smartphone purchase, the biggest factor in influencing customer satisfaction was found to be 'Usability Effect' while the biggest factor in influencing customer loyalty was revealed to be 'Brand Effect.' As a result, this study could learn that it's necessary that 'Usability Effect' should be considered more preferentially than other factors in order to enhance customer satisfaction while 'Brand Effect' should be preferentially considered in orderto raise customer loyalty. Third, it can be judged that in the relationship between customer satisfaction and customer loyalty, the bigger the customer satisfaction, the higher the customer loyalty. It is hoped that such research results could be applied as useful materials in time of establishing the marketing strategy. Nevertheless, this paper makes it clear that due to the constraints in the number of sample areas and samples, there is a limit in objectifying the research results into all areas.
