  • Purpose - Port is vital for international trade accounting for approximately 80% of world cargo transportation in the global trade sector. Air pollutants emitted owing to the related industry interfaces developed around the port spread throughout the dense population region can have harmful effects on the nearby residents. This study aims to analyze high-concentration diffusion pattern by air pollutants, considering the main management periods by air pollutants. Design/methodology - Employing the concentration criteria per main air pollutant, the analyses of concentration change patterns per air pollutant, wind characteristics that directly affected the air pollutant diffusion, distribution types per air pollutant, and high-concentration diffusion patterns by season according to time changes were conducted. Findings - The substances that caused harmful levels of air pollution in the hinterland living zone of the Busan New Port were PM_10, PM_2.5, and NO_2. Furthermore, the intensive management periods were as follows: For PM_10, 24-h (spring), 12:00-16:00 (summer), 12:00-16:00 (summer), 20:00-12:00 (fall), and 24:00-20:00 (winter), and for PM_2.5, 24-h (all four seasons), and for NO_2, 23:00-04:00 (spring), 23:00-08:00 (summer), and 20:00-08:00 (fall), and 23:00-04:00 (winter). Originality/value - Research finding indicates that regular monitoring and countermeasures to reduce air pollution for each air pollutant makes it possible to achieve effective air quality control in the port and hinterland living zones.

  • Maritime transportation is one of the most complicated and hazardous business fileds. Maritime accidents still occur despite several precautions since maritime is exposed to natural factors more than any other industries. In this harsh environment as a part of their job, marine pilots often embark/disembark to/ from vessels and confront life-endangering personal accidents. In the maritime field, several risk assessments are applied. However, all of them could not evaluate occupational accident risk for maritime pilot specifically. This paper performs specific risk analysis using the bow-tie method based on past accident records. This paper aims to qualify root causes and quantify root causes by importance level according to occurrence probability. As a result of analysis, occupational accident occurrence probability is found to be 14%, indicating that accident occurrence rate is significantly high. Hence, the probability of root causes triggering accidents and accident occurrence probability can be ascertained so that preventive measurements can be implemented. Besides theoretical achievement, this paper provides safety awareness to marine pilots, Marine Pilot Organizations, and ship crew who play a key role during marine pilots' transfer.

  • 평택항은 2001년 ‘평택항 종합개발 기간계획 정비용역’ 에서 선박의 내항 이용 방법이 갑문식에서 감조식으로 변경됨에 따라 기 건설된 서해대교 입구의 남측호안을 철거하여 선박이 상시 내항을 이용할 수 있도록 계획중이다. 이에 이 연구에서는 남측호안이 철거된 후 평택항을 고려하여 서해대교 하부를 통항하여 내항에 안전하게 입출항이 가능한지를 이론적 고찰 및 풀미션시뮬레이터를 이용하여 평가하고 문제점 발생시 대안을 제시한다.

  • 항만간 허브항 경쟁이 극심해 지고 있는 오늘날, 컨테이너 선사는 M&A 및 전략적 제휴로 컨테이너터미널 운영사와의 가격 협상력의 우월적 지위를 갖게 되어 컨테이너터미널 운영사간에 선사 및 화물유치를 위한 경쟁을 더욱 부추기고 있다. 그러나 수요측면에서 컨테이너물동량 증가율 둔화로 컨테이너터미널에서 처리해야 할 물동량은 한정되어 있는 반면, 공급 측면에서 항만터미널의 지속적인 건설은 항만간 또는 터미널간 물량 유치경쟁을 과열시키고 있다. 특히 부산항은 신항 개장이후 북항과 신항간 물동량 유치경쟁으로 인하여 항만하역시장의 교란을 가져오고 있다. 본 연구에서는 부산항 컨테이너 항만하역시장의 구조적 특성분석과 설문조사 방법론을 통하여 향후 부산항 항만 하역시장의 안정화 방안을 제시하고자 한다. 하역시장 안정화 방안으로 항만하역 요율결정체계 개선, 요금신고제도의 개선 및 공정경쟁규약의 제정 등과 같은 법 제도적 개선방안과 컨테이너터미널 운영사별 처리물량 상한제를 도입을 전제로한 항만풀링제도 및 물량연동 임대료제도의 도입방안을 제안한다.

  • From the viewpoint of coastal hydrodynamics, one of the most important effects of global warming is a sea-level rise in coastal areas. In the present study, impacts on port facilities against sea-level rise were investigated. The sea-level rise causes the increase of the water depth, and it generates variations on the wave height, buoyancy, tidal system and nearshore current system and so on. The increase of water depth gives rise to the decrease of crown height of the structure and it causes increase of wave overtopping quantity. It may flood the port zone and its facilities, and may decrease harbor tranquility. It also leads to difficulties on navigation, mooring and loading/unloading at the port. Increase in water depth also causes increase of wave height in surf zone. This high wave makes structures unstable and may cause them to collapse during storm. In addition, increase in buoyant force due to sea-level rise also makes the gravity type structures unstable. Consequently, theses variations due to sea-level rise will cause functional deterioration of port facilities. In order to protect port facilities from the functional deterioration, reinforcement plan is required such as raising the crown height and increase in block weight and so on. Hence proper estimation method for the protection cost is necessary in order to protect port facilities efficiently. Moreover response strategies and integrated coastal zone management plan is required to maintain the function of port facilities. A simple estimation of cost for breakwaters in Korea was performed in the present study.

  • For a nearly decade Busan has been the pre-dominant force in Northeast Asian port community, but during the last couple of years, several competitors have looked to directly challenge Busan's regional dominance, most notably, northern Chinese ports. Faced with this challenging and formidable trend, Busan has had to respond appropriately to ensure that Busan remains a regional hub well into the 21st century. The aim of this paper is to make some considerations for a regional hub container port in Northeast Asia in response to changes in the shipping industry with particular reference to Korea.
