Norovirus (NoV) causes major acute non-bacterial gastroenteritis in humans. NoV genus is a member of the family Caliciviridae, which is transmitted by contaminated food and water or from human to human. Many genotypes of genogroups I and II have been reported because of their high genetic diversity. To obtain molecular epidemiological information on gastroenteritis sporadic cases in Busan, Korea, we analyzed the nucleotide sequences of NoV strains detected during 2008~2010. We performed one step RT-PCR amplifying the open reading frame (ORF) 2 (capsid region) followed by semi-nested PCR. Fecal samples were collected from 4,071 acute gastroenteritis, and genotypes of the 421 positive samples were determined by sequence analysis. Based on partial sequence of capsid region, 7 NoV were categorized into genogroup I and 13 into genogroup II. Prevalent genotypes among gastroenteritis patients within Busan were GII.4, GI.6, GII.5 in 2008~2010. The results of this study will contribute to the currently available epidemiological data and improve public health and hygiene via development of diagnostic methods and sustainable surveillance.

The purpose of this study is to propose ways of promoting medical tourism in Busan. For the purpose, this researcher made a questionnaire survey of Japanese tourists who used in Busan International Ferry Terminal between January and April 30, 2008. Findings of the study can be summarized as follows. 86.3% of all respondents had never experienced any medical service in Korea. 57.3% said that the most important thing is the level of medical technology. Most of respondents preferred massage treatment using spa and sea water, followed by Oriental medical services. To make medical conditions(price competitiveness, high-level medical technology, high-quality medical facilities) of Busan properly informed to the outside, it is required to make the city itself more internationally recognized through public relations and strengthening individual medical services provided in the city. It is also required to build up a non-stop service system that helps foreign tourists not only easily use medical institutions, but also better cope with a variety of problems that they might face during stay in the city. To be more trustable to foreign patients, medical services of Busan should be certified by JCI. Furthermore, it is very much needed to develop products which connect medicine with tourism, for example, such programs that combine medical services, tourism, recreation and leisure.

This study explores ways to improve the actual conditions of ocean environment by conducting a comparative study on the current sea-water quality of Busan Metropolitan City and Incheon Metropolitan City that are representative sea port cities in Korea. The indices used to evaluate the sea-water quality include water temperature, salt content, PH, DO, COD, DIN, T-N, DIP, T-P, Sio2-Si, floating materials, and Chi-a. The findings of the analysis can be summarized as follows: First, ocean environmental states of Busan Metropolitan City and Incheon Metropolitan City are getting increasingly worse between the year of 2000 and 2003. Second, T-N, DIP and T-P have been main contributors in worsening ocean environmental states of Busan Metropolitan City and Incheon Metropolitan City.

Port Authority System has been regarded as one of the most efficient ways of port administration. The Korean government is now planning to setup PA system in Busan. Busan New Port is located in Kadok Island the ownership of which Busan City and Kyongnam Province have partly of jointly. So The new PA system is expected to have many complicated problems between Busan City and Kyongnam Province in many aspects. The purpose of this paper is to provide an empirical methodology about the best approach to these problems using AHP(Analytic Hierarchy Process).

This study intends to demonstrate that the population decrease in the City of Busan has been resulted from the move of the city's population towards suburbs as well as the out-migration towards the Seoul metropolitan area. To grasp the pattern in the spatial shift of the Busan's population, I analyze the change of population and households within the city and the migration at the inter-regional and intra-metropolitan scales. The major findings of the study are as follows: First, Busan has experienced population decline since 1995, as other large cities, such as Seoul and Daegu have done. Second, despite the population decrease, the number of households has been increased in Busan. Third, the residents of Busan have mostly moved not only to the Seoul metropolitan area but also to the suburban region of Busan. This finding may well contradict the long-standing belief that the continued decrease in the Busan population could be the result of the out-migration toward the Seoul metropolitan area. Fourth, the residential suburbanization in Busan can be interpreted as the extensive intra-metropolitan dispersion, which means the growth of the Busan metropolitan area.

As can be seen in many earthquakes, liquefaction causes differential settlement, which sometimes produces serious damages such as building destruction and ground subsidence. There are many possible active faults near the Busan city and the Yangsan, Dongrae, and Ilgwang faults among them pass through the city. The Busan city is also located within the influence of recent earthquakes, which occurred in the Gyeongju, Pohang, and Kumamoto (Japan). Along the wide fault valleys in the city, the Quaternary unconsolidated alluvial sediments are thickly accumulated, and the reclaimed lands with beach sediments are widely distributed in the coastal area. A large earthquake near or in the Busan city is thus expected to cause major damage due to liquefaction in urban areas. This study conducted an assessment of the liquefaction hazard according to seismic recurrence intervals across the Busan city. As a result, although there are slight differences in degree depending on seismic recurrence intervals, it is predicted that the liquefaction potential is very high in the areas of the Nakdonggang Estuary, Busan Bay, Suyeong Bay, and Songjeong Station. In addition, it is shown that the shorter the seismic recurrence interval, the greater difference the liquefaction potential depending on site periods.

Adenovirus (ADV) and human bocavirus (hBoV) cause acute respiratory tract infections, and are often associated with increased rates of hospitalization and death, particularly in infants and young children. The aim of this study was to analyze the clinical features and molecular phylogeny of ADV and hBoV isolated in Busan, from January 2011 to November 2013. In total, 3,230 specimens (throat swabs) were collected from patients with influenza-like illnesses and acute respiratory tract infections. Multiplex real-time RT-PCR was performed to detect eight respiratory viru [rhinovirus, adenovirus, respiratory syncytial virus, human coronavirus, human metapneumovirus, human bocavirus, parainfluenza virus and influenza virus] and detected 1,485(46.0%) cases. Among 1,485 positive specimens, 257(8.0%) cases were ADV and 68(2.1%) cases of hBoV. A significant clinical feature of ADV is fever and headache whereas hBoV is wheezing. Serotypic distributions of isolated ADV and hBoV were analyzed by sequencing of hexon and VP1/VP2 gene, respectively. ADV was identified seven different serotypes(1~6, 8), revealing a high similarity among the isolates (>97%). The predominant types of ADV were type 1 in 2011, type 3 and 4 in 2012, type 3 in 2013, respectively. ADV type 3 was major causative type during outbreaks in 2013. All of the hBoV was identified as hBoV type 1.
