While maritime arbitration industry has not been prevalent in Korea, Korea ranked fifth in terms of export volume and its shipbuilding industry ranked top globally in shipbuilding order volume in 2020. The discrepancy between the maritime industry's productivity and relative lack of maritime arbitration has had a negative impact on Korea's economic development. To address these problems, this paper i) reviews preceding research, ii) examines the Korean maritime arbitration system's status and analyzes the KCAB's maritime arbitration statistics from 2005-2020, iii) examines major foreign maritime arbitration institutions' status and strategies including LMAA, SMA, SCMA, and HKMAG, and lastly iv) suggests practical ways to promote maritime arbitration in Korea. The Suggestions for promoting maritime arbitration are 1) to prepare and promote various maritime standardized forms for the Korean shipping industry, 2) to insert an arbitration clause in medium and large-size Korean shipping firms' B/L clause, 3) to expand professional maritime manpower training and other infrastructure, and 4) to enhance the predictability of the result of arbitration through maritime arbitral awards or by examining the feasibility of the appeal system against the arbitral award only on a point of law in the future. In conclusion, the success or failure of promoting maritime arbitration in Korea depends on the will, passion, cooperation and practice of the most important key players in maritime arbitration, such as the Asia Pacific Maritime Arbitration Center (APMAC), the Korean Commercial Arbitration Board (KCAB) and the Seoul Maritime Arbitrators Association (SMAA).

In this paper an inter-layer protocol, referred to as a Multi-Network Selector (MNS) is proposed for multiband maritime networks. A MNS is located between the data-link layer and the network layer and performs vertical handover when a ship moves another radio network. In order to provide seamless data transfer to different radio networks, the MNS uses received signal strength (RSS) and ship's location information as decision parameters for vertical handover, which can avoid ping-pong effect and reduces handover latency. In addition, we present related issues in order to implement the MNS for a multiband maritime network.

Yaw-checking and course-keeping ability in IMO's ship manoeuvrability standards are reviewed from the viewpoint of safe navigation. Three kinds of virtual series-ships, which have different course instability, are taken as test models. The numerical simulation on Z-test is carried out in order to examine the correlation between known manoeuvrability in spiral characteristics and various kinds of overshoot angle. Then simulator experiments are executed with series-ships in a curved, narrow waterway by six operators(five active pilots and one ex-captain) in order to examine the correlation between known manoeuvrability and degree of manoeuvring difficulty. IMC criteria for yaw-checking and course-keeping ability are discussed and revised criteria are proposed.

In order to control a LTI(Linear Time Invariant) system subjected to system noise and measurement noise, first of all, it is necessary to estimate the state of system with reliability. Kalman filtering technique has been widely used to estimate the state of the stochastic LTI system with stationary noise characteristics because of its estimation ability versus algorithm simplicity. However, it often fails to estimate the state of the LTI system of which system parameter uncertainty exists partly and/or input uncertainty exists. In this paper, a new estimation technique based on Kalman filter is suggested for stochastic LTI system under parameter uncertainty and/or input uncertainty. A fuzzy estimation algorithm against uncertainties is introduced so as to compensate the state estimate filtered by Kalman filter. In order to verify the state estimation performance of the suggested technique, several simulations are accomplished.

In order to construct an Anechoic Chamber satisfying international standards for EMI testing, it has been recognized that the absorption characteristics of the EM wave absorber must be higher than 20 dB over the frequency band from 30 MHz to 18 GHz. In this paper, an EM wave absorber with super wide-band frequency characteristics was proposed and designed in order to satisfy the above requirements by using the Equivalent Material Constant Method(EMCM) and Finite Difference Time Domain(FDTD). The proposed absorber is to attach a pyramidal absorber onto a hemisphere-type absorber on a cutting cone-shaped ferrite. As a result, the proposed absorber has absorption characteristics higher than 20 dB over the frequency band from 30 MHz to more than 20 GHz.

세월호 사고 이후 내항선 분야의 해사안전관리를 강화하기 위하여 해사안전감독관 제도가 도입되었다. 이들은 선박에 대한 정기 및 수시 지도·감독 중 선박의 시설 분야에서 중대한 결함사항이 발견되면 시정이 완료될 때 까지 선박의 항행을 정지하는 행정처분을 하고 있다. 항행정지명령은 내항선박에 대하여 해사안전감독관이 행사하는 강장 강력한 규제행위의 일종이다. 선박의 안전과 해양환경보호를 위한 해사안전감독관에 의한 내항선박의 지도·감독의 중요성은 아무리 강조해도 지나치지 않을 것이다. 그러나 각 지방해양수산청의 선박에 대한 규제의 정도는 이를 집행하는 사람에 따라 다소의 개인차가 있을 수 있으며, 집행과정에서 개인의 고의 또는 과실이 발생할 수가 있다. 지방해양수산청에 의한 선박의 억류는 선박운항 상의 지체를 가져오기 쉽고, 용선계약의 정지에 의하여 선박의 소유자는 많은 경제적 손실을 입을 수 있다. 그럼에도 불구하고 해사안전법에서는 해사안전감독관에 의한 항행정지명령의 행정처분에 대하여 이의신청과 같은 불복절차를 규정하지 않고 있다. 따라서 이러한 문제점을 극복하기 위하여 지도·감독의 근거가 되는 해사안전법 상에 개인의 고의 또는 과실에 의한 부당한 항행정지 행정처분에 대하여 이의신청을 통한 권리의 구제가 가능하도록 제도를 개선해야 한다.

Competitive and reliable maritime transport services benefit the economy as a whole, and are key efficiency factors for the production of both goods and services. Although maritime transport sector is very liberalized compared to many other service sectors, certain obstacles must be overcome before full liberalization of the maritime transport can be realized. Particularly, maritime transport services in Northeast Asia are regulated by a complicated and outdated system. To remove these barkers two approaches can be used: a regional trading arrangement approach and a multilateral approach via WTO. However, multilateral efforts are not likely to be successful in achieving any concrete progress towards maritime transport liberalization in the short- to medium-term in Northeast Asia. Consequently, it may be the best to take the following two progressive approaches and to make them work towards liberalization of the maritime transport market: a bilateral approach and a trilateral approach. A gradual process of liberalization would expand the market, help operators achieve economies of scale, promote the international division of labor and specialization, enhance the effective management of shipping services, and promote the long-term interests and welfare of the user by improving service quality and diversifying services. A liberalized and integrated maritime transport market in Northeast Asia should achieve both of these long-run policy objectives by benefiting both the transport service users and the transport service providers. In order to move the maritime transport liberalization programs as quickly as possible, it is desirable to establish a "Regional Maritime Transport Liberalization Committee." We suggest it to be a Tripartite (China, Japan and Korea) Committee initially, which can later expand its membership to include other Northeast Asian countries.

Accidents and incidents caused by poor performance in the maritime industry suggest the need to find ways to improve performance in order to operate effectively and improve safety. The data for this study was collected from maritime students and involves the performance and levels of intrinsic and extrinsic motivation. Various motivational factors were identified and the ways in which these factors relate to performance was analyzed. The importance of considering motivation when recruiting new trainees and workers, and continually looking for ways to increase intrinsic motivation, is stressed throughout this paper. The results suggest that high levels of good quality motivation correlate positively with better performance.
