The purpose of this paper is to analyze the competitiveness between Busan New Port and Shanghai's New Yangshan Port, on an island 20 miles off the Chinese mainland coast. For this aim, the paper examines backgrounds of Yangshan Port construction and its related projects, namely, Donghai Bridge and Luchao Logistics Park including operation strategies of Yangshan New Deepwater Port. The main results of this paper are as follows: Busan New Port has competitive advantage over Yangshan Port in terms of ideal location, especially in Asia-North America route, and connection between terminal and hinterland logistics park. Because Busan New Port is operated by fully on-dock system. Nevertheless, Yangshan Port has more strength in its centrality, port tariff and port productivity, which are represented by crane productivity, quay productivity and area productivity. Therefore, Korean ports are recommended by transformation from cargo attraction-type to cargo generation-type port through early activation of port logistics center along with Free Economic Zone.

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).

Spontaneous hemothorax is rare, with limited data available on its etiology and treatment. We report a case of massive spontaneous hemothorax with a ruptured variceal phrenic vein during pregnancy, likely a complication of the Kasai procedure. Despite closed thoracostomy, the patient's symptoms and imaging findings did not improve. Emergent open thoracotomy and bleeding control were performed.

Objectives: Mobile phones have become one of the most essential accessories in daily life. However, they may act as reservoir of infectious pathogens if they are used without hygienic practices in their handling. Therefore, this study aimed to isolate food-borne pathogens from mobile phones and investigate the characteristics of toxin genes and antibiotic susceptibility patterns. Methods: A total of 146 mobile phones were collected from 83 middle- and 63 high-school students in Busan. The surfaces of the mobile phones were aseptically swabbed. Results: Among the food-borne pathogens, Staphylococcus aureus, Bacillus cereus and Escherichia coli were detected in 26 (17.8%), 20 (13.7%) and four (2.7%) samples, respectively. There were no statistically significant differences according to school level, gender or phone type. None of four E. coli strains had pathogenic toxic genes. All of the B. cereus strains carried at least three different toxin genes among the nine enterotoxin and emetic toxin genes. Three out of 20 B. cereus strains (15%) possessed emetic toxin genes, which are rarely detected in food-poisoning cases in Korea. Among the 26 strains of S. aureus, the detection rate of staphylococcal enterotoxin genes, toxic shock syndrome toxin (tsst) and factors essential for methicillin resistance (femA) were 84.6%, 7.7% and 100%, respectively. In the antibiotic susceptibility test, there was no methicillin-resistant S. aureus (MRSA) or vancomycin-resistant S. aureus (VRSA). Conclusion: The results show that students' mobile phones in Busan were contaminated by food-borne pathogens which carried various toxic genes. Therefore, regular phone disinfection and hand hygiene is important in order to reduce cross-contamination.

The objectives of the present study were to assess the oxidative stability of South Korean n-3 (omega-3 fatty acid) supplements carried out from 2018 to 2019 and evaluate the influence of product characteristics on oxidative safety. A total of 76 n-3 supplements were analysed for oxidation safety by four markers, including acid value (AV), primary oxidation (peroxide value, PV), secondary oxidation (p-anisidine value, pAV) and total oxidation value (TOTOX). Among the supplements tested, 5.3 %, 55.3 %, 28.9 % and 46.1 % exceeded the international voluntary recommended levels for AV, PV, pAV and TOTOX, respectively. Purity (%) of products, remainder of expiration date (suggested shelf life), package in press through package (PTP) and products with additives had statistically significant differences oxidation assessment levels (p < 0.05). In addition, n-3 group found in Algae oil had significantly lower AV levels than the group that did not, and product with Alaska pollack oil, had significantly higher pAV levels than without group (p < 0.05). The high oxidation status of South Korean n-3 products in the present study could not be considered a public health problem right now. However, the levels of oxidation may affect a lot the efficacy and safety of using n-3 supplements. Thus, current oxidation safety limits should be reestablished by regulatory bodies to ensure the safety and efficacy of n-3 supplements, so that the standards could be applied to the products available to consumers.

This study suggests a strategic direction for developing the Port of Busan based on evaluating and prioritizing the relative importance of competitiveness factors for ports using SWOT analysis and the analytic hierarchy process (AHP) method. The Port of Busan is the world's sixth largest container port and the largest port in South Korea. The Port of Busan constitutes a key industrial infrastructure for an exporting country. Despite the economic and industrial importance of the Port of Busan, little research has examined its strategic development. This study derives a SWOT matrix for evaluating the competitiveness of factors from previous studies and expert reviews, and it constructs a hierarchical analysis structure model based on the SWOT matrix. To deduce a strategic direction for developing the Port of Busan, a questionnaire based on SWOT·AHP was distributed to industrial and academic associations to prioritize competitive factors. This study presents four strategic tactics based on strengths (S), weaknesses (W), opportunities (O), and threats (T) (S/O, S/T, W/O, and W/T) as strategic directions for developing the Port of Busan. This study will contribute objectively to the overall effort by the government to improve the operation of the Port of Busan and establish development strategies.

Objectives : With the observation of factors influencing depression, self-reported happiness, self-reported stress and suicidal attempt, this study compared and evaluated the mental health of adolescents from multicultural families and monocultural families in Korea. Methods : This study compared the characteristics of adolescents from multicultural and monocultural families based on the analysis of data of The Tenth Korea Youth Risk Behavior Web-based Survey and analyzed the factors influencing adolescent depression, self-reported happiness, self-reported stress and suicidal attempt. Results : There was no significant difference in the levels of depression, self-reported happiness, and self-reported stress between adolescents from multicultural and monocultural families. However, suicidal ideation and suicidal attempt were significantly higher in adolescents from multicultural families. Conclusion : There was no significant difference between the mental health of adolescents from multicultural and monocultural families. Because depression is the greatest factor for suicidal attempt, and violence has stronger relationship with depression of adolescents from multicultural families, further study is needed to prevent this trend.
