In order to obtain and maintain competitive advantage, under rapidly changing maritime environment, liners should make efforts to reinforce their logistics service capabilities. Most of all, for this, shipping lines should accurately recognize and evaluate their logistics service attributes. In the present research, various logistics service attributes for ocean carriers were selected from previous studies and the observed data for 6 main service attributes were collected through a questionnaire survey to 31 maritime experts. Moreover, shipping lines' relative logistics service capabilities were measured by an additional survey process. The comparative gravity between core evaluation factors were measured by AHP technique and the relative capability levels of 2 Korean liners and 5 foreign shipping companies were assessed by utilizing a fuzzy model. The empirical result presents that Korean liners are superior at customer service capability but inferior at freight rate competitiveness. This research shows that Korean liners are ranked at high position for overall logistics service capabilities and focusing on the differentiation strategy but not on the cost related strategy.

Perception level and social position of radiological technologist influence satisfaction level of their job. This study aims to use foundational data to improve perception level and social position of radiological technologists. We conducted interviews and a fill-out survey with 233 students who have been majoring in health-related fields at five universities and colleges located in Busan and who finished internship programs. The study analyzed 233 answer sheets excluding 17 inadequate answer sheets using T-test, ANOVA and multiple regression analysis with SAS9.1. The mean score of perception level was $3.33{\pm}0.56$. The personal image of radiological technologist showed the best score($3.43{\pm}0.56$) whereas the social image showed the worst($3.12{\pm}0.58$). According to the classification of the subject, the answer, "radiological technologist is specialized job", showed the best score($3.99{\pm}0.79$). The answer "radiological technologist suffered from less stress and workload than others when they work usually" showed the worst score($2.88{\pm}0.98$). According to the classification of each health-related major, the mean score of students who are a major in the department of the radiological technologist was the best($3.46{\pm}0.46$) and the students who are major in department of the physical therapy was the worst($3.24{\pm}0.40$).

2008년부터 시작된 세계경제 위축은 전 세계 해상물동량 감소로 이어져 컨테이너선업계의 불황이 더욱 심화되고 있다. 선사들은 불황을 극복하기 위하여 여러 가지 전략들을 구사하고 있다. 대부분의 선사들은 잉여 선박의 추가투입으로 감속운항을 통해 선박 운영비용을 절감하고 있는데, 이와 같은 시도는 선사입장에서는 비용절감이 되지만 감속운항이 화물의 정시성을 저해하는 요소로 작용하고 있기 때문에 화주입장에서는 불만요인이 될 수 있다. 이러한 상황에서 'M'선사는 "On Time Delivery"를 보증하기 위해서 아시아-유럽항로에서 새로운 서비스인 Daily Maersk Service를 2011년 10월부터 적용하고 있다. 본 서비스는 아시아발 북유럽행 특정 기간 포트구간 수송에서 100% "On Time Delivery"를 보증하고, 또한 매일 화물수탁을 가능하게 한 신서비스이다. 본 연구에서는 업계 1위를 달리고 있는 'M'선사가 감속운항을 하면서도 화물의 정시성을 높이기 위해 실시하고 있는 Daily Maersk Service를 통하여 가격 경쟁과 더불어 서비스 경쟁에서도 우위를 확보하려는 전략이 효과를 나타내고 있는 지에 대하여 사례연구를 통하여 확인하였다.

The purpose of this study is to Analyze the problems that container shipping companies exist through the commercialization of container shipping for Non-Arctic countries and the opportunity factors for the transport of the Arctic shipping to improve cooperation cross-border relation Arctic policy and the use of transport. In order to design a hierarchy analysis method study model, four high and 17 low factors were extracted by designing a hierarchy analysis method study model based on results by prior study and in-depth interview. The first of the higher factors is the internal strength of assessing the value of the Arctic, the will and capabilities of the shipping companies in creating new markets with the vision and goals of the shipping companies. Second, the internal constraints associated with the shipping companies advance to the NSR mean the negative factors for the entry into the NSR and the internal weaknesses that cause the shipping companies capacity limitations. Third, the economic benefits from the use of NSR are external factor for shipping companies in cooperation with the future economic value of the Arctic and with respect to Arctic sea and Arctic advance and development from Arctic coastal countries. Finally, external pre-emptive tasks means to respond to use NSR by external restrictions on transport to prepare the possibility of severe weather conditions, the customs policy change of coastal countries.

In this paper, we estimate the difference of port preference and attributed importance by diving subjects of the survey into internal and external shipping companies considered as the main customers of port. From the results of conjoint analysis, it is found that there are differences in preference between domestic shipping companies and foreign ones. The difference in port preference shows; foreign shipping companies mark Shanghai port in the first place in the preference of transshipment port, while domestic shipping companies prefer Busan port. Similar results are applied to preference of rolling port. The result of the survey means it is necessary to group shipping company, when port is analyzed, because the port preference is subject to wether internal or external shipping companies. Also, it implies target marketing strategies should continuously be needed in order to maintain Busan port's preference gaining advantage over other ports and major target would be shipping companies.

발주잔량의 감소와 세계경기 회복기조 등을 감안할 때, 수급여건은 저점에 근접해 있다. 그러나, 해상물동량 증가율의 둔화, 대형선박 위주로 되살아난 발주 등을 감안할 때, 운임지수 등 시황회복은 상대적으로 느리게 진행될 전망이다. 2012년부터 상위선사의 뚜렷한 실적차별화가 나타나고 있으며, 국내선사는 상대적으로 취약한 선종다각화와 자본력, 계열 및 정부의 저조한 지원 등으로 금융위기 이후 재무구조가 가장 큰 폭으로 악화되었다. 상위선사의 실적우위는 일시적 차이가 아닌 선박의 대형화와 높은 연료효율성, 우수한 글로벌 네트워크 등 구조적 원가경쟁력의 차이에 기인하고 있다. 상위 3개 선사는 초대형선박의 추가인수와 P3 Network 구축으로 원가경쟁력이 더욱 향상될 전망이며, 재무여력을 갖춘 경쟁선사들도 선박가격이 낮은 상황에서 고효율의 대형선박을 발주, 원가경쟁력을 제고하고 있다. 반면에 호황기 고가에 선박을 확보한 국내선사는 과중한 재무부담으로 인해 선박대형화와 글로벌 네트워크 구축에 동침하지 못하고 있어 원가경쟁력의 차이는 더욱 심화될 전망이다. 더딘 시황회복과 상위선사의 단위당 운송비(Unit Cost) 하락 등을 감안할 때, 빠른 시일 내에 운임상승을 통한 큰 폭의 성과개선을 기대하기 어렵고, 과중한 재무부담은 투자여력의 위축으로 이어지고 있다. 여기에 중국 유럽선사가 정부로부터 대규모의 직접적 지원(대출, 지급보증)을 제공받고 있는데 반하여, 우리 정부는 장기적 관점의 지원이나 대책을 유보한 채, 제한된 유동성 지원만을 하고 있다. 재무부담에 따른 악순환을 깨고 원가경쟁력을 확보하기 위해선, 비핵심자산 매각, 자본유치 등 구조조정을 통한 재무구조 개선, 투자여력 확보를 통한 글로벌 경쟁력 회복, 정부차원의 지원과 조정 등 가능한 모든 방안을 총 동원하여 재무구조를 개선하고 투지에 나서는 것이 시급하다. 하지만, 불황으로 체력이 소진된 해운사의 자체적인 노력만으로는 한계가 있다. 기간산업의 국가경쟁력 차원에서 국내 선사의 자체노력은 물론, 정부 또는 금융기관 등 유관기관들의 확실한 지원이나 의사결정이 필요한 시점이다. 그렇지 않을 경우 국내 해운산업은 어두운 터널의 끝을 벗어나지 못하고 글로벌 경쟁사와의 격차는 더욱 벌어지게 될 것이다. 다음은 한국신용평가에서 발표한 "풍전등화 국내 해운업계, 본원적 대책 마련 시급"의 주요 내용을 요약 정리한 것이다.

Corporate social responsibility (CSR) is gaining significance in various industries and academic research. However, shipping companies have a relatively less interest in CSR. Considering the International Maritime Organisation's (IMO) 2020 model and its focus on sustainability, it is time for shipping companies to consider the active use of CSR initiatives. This study aims to examine the leading factors influencing CSR implementation and job satisfaction. The analysis was conducted using partial least squares and statistical package for social sciences 18.0 to achieve the research objectives. The results showed that the internal and external factors of shipping companies play a positive role in CSR implementation, which was found to play a positive role in enhancing job satisfaction. The implications of this study are to identify factors that drive shipping companies to improve their CSR performance.

This study analyzed the changes in the operational productivity of fourteen Korean container lines from 2019 to 2021 using MP I(Malmquist Productivity Index). The results indicated that the operational productivity of the shipping companies has increased by 38.4% annually, representing the TCI (Technical Change Index) increasing by 58.3% and the TECI (Technical Efficiency Change Index) decreasing by 12.6%. The increase in the operational productivity of the container shipping lines was mainly attributed to the high rise in ocean freight rates rather than an increase in fleet size or ship technical efficiency. However, the deep-sea shipping lines (i.e. HMM and SM lines) experienced increases in both the TCI and TECI, which was not the case for other shipping lines(i.e. Intra-Asian short-sea shipping lines). The intra-Asian short-sea shipping lines enhance their productivity due to the TCI but failed to appreciate the cost savings of the increased fleet effects due to the low SECI(Scale Efficiency Change Index) values.
