Gastric cancer (GC) is the fifth most common cancer in the world, with a wide variation in incidence rates across different geographical areas. In Iran GC is the most common cancer in males and it is reported to be the third most prevalent after breast and colorectal in females. A geographical information system (GIS) allows investigation of the geographical distribution of diseases. The purpose of the present study was to explore the relationship between gastric cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. Of all cases, 672 (73.8%) were in males with a sex ratio of 3 to1. The highest incidence by cities was seen in Namin with 137.5 per 100,000. The results of this study showed that the distribution of GC around the Sabalan volcanic mountain was significantly higher than other places in the same province. These results can be considered as a window to future comprehensive research on gastric cancer.

Phylogenetic relationship and DNA polymorphism among local populations of the Asparagus cochinchinensis have been investigated based on nuclear ribosomal DNA ITS sequences and RAPD analysis in Korea. In result, two genetically distinct groups of local populations except Geoje were recognized by the phylogenetic tree both in rDNA-ITS and RAPD. One was called 'western coast group' that includes the Buan 1, 2 and Taean and the other was 'southern coast group' that includes Haenam, Yeosu and Namhae. Thus, the geographical relationship of Asparagus cochinchinensis was two well-typified clades. These results suggest that the geographical genetic variation of Asparagus cochinchinensis is closely connected with the slow and long period of propagation via the coast in Korean Peninsula.

Radio navigation aids are very important elements to provide information necessary for safe navigation using radio waves. Recently, the number of radio equipment using radio waves is increasing, and the air frequency interference by adjacent channels is very high. In addition, the use of irregular jamming that threatening radio navigation aids and satellite navigation system frequency is rapidly increasing. Therefore, it is urgent to ensure the safety of air waves. In this paper, we investigated the characteristics and frequency of the domestic navigation system. And we were analyzed the geographical separation standard for implementation of analysis program. Also, we implemented a program for the geographical separation distance analysis that applying international standards and recommended practices.

Human life has been inextricably linked with healing. Recently, as the demands of healing are higher, it is more necessary to study spaces, places and mobilities related to healing in geographical studies. This paper draws on a case study of urban peoples walks along Seoul City Wall to explore what healing factors affect the people walking along historical landscapes in urban center and understand geographical implications of the healing process. Based on the concept and analytical lens of 'therapeutic mobilities' introduced by Gatrell, this research analyzes texts written on 181 blogs. The results show the main factors that affect their healing are 'weather climate', 'walk stroll', and 'nightscape'. Futhermore, the blogs' narratives focusing on these main factors imply healing place-making, time as limiting factor, and the social body within nightscape in the healing process.

The aged population in Korea, especially in rural areas, has been growing rapidly. The welfare for the rural elderly has become a major concern, however we don't have enough information about that population; we don't even have detailed demographics of it. The present research is aimed at; 1) investigating the tendency and changing geographical distributions of the rural elderly, and 2) introducing GIS(Geographic Information Systems) as a useful tool in analyzing geographical distributions of the aged. The General Census Data from 1960 to 2000 was used to carry out this study. The major findings are; 1) There has been a gradual decrease in the rural population over the past 40 years, but this tendency has slowed down more recently; 2) It was observed that the 'oldest-old' group aged 85 years old and over has actuality increased in rural areas faster than any other age group; 3) The changing patterns of the elderly population were different in metropolitan areas and rural areas. In brief, there are far more aged people, especially of the 'oldest-old' group and females in rural areas than those in urban areas. These population, the 'oldest-old' or females, are the most vulnerable and have the greatest need for social welfare and social services of different kinds.

The study seeks to identify factors affecting the choice of a university by first-year Business Administration students in Vietnam. Probability sampling is using Stratified sampling of 500 students from five private universities in Ho Chi Minh City surveyed by convenience sampling. This paper employs mixed research methods - measuring Cronbach's Alpha, EFA, Regression and using PATH model - to test the hypotheses of the research model. The results of the study identify five factors: Prestige, Geographical location, Facilities, Attractiveness of the field and Media. All these factors have a positive influence on the standing of the university brand. It means that the higher the Prestige, Geographical location, Facilities, Attractiveness of the field and Media, the higher the university brand. The results indicate that Geographical location is the most influential factor to enhance the private university's brand. Bringing Geographical location is, thus, advisable to enhance a university standing. The brand plays a determining role in students' trust when selecting a university. Media is still the top concern of new students when they choose to study at a university. Media still remains an important consideration for new students when choosing a university. So, this factor should be utilized by universities to enhance their attractiveness.

In general, GIS provides a user with geographical information according to his requirements after a computer stores digitized spatial data from real scenes. Geographical information from digitized spatial data lacks of reality due to the exclusion of real scenes. However, Augmented Reality(AR) allows a user to see the real world with virtual objects superimposed upon or composited with the real world. Therefore it enhances a user's perception of the real world. In this paper, we present the development on 3D geographical information guide system using augmented reality that displays the real world with virtual objects such as building name, road name, etc., in real time.
