Environment of marine transportation market is changing rapidly. Due to globalization of world economy, marine transportation of cargos, especially trade using container boxes, is increasing dramatically. Fierce competition in the global market of container transportation forces the shipping industry to seek the economy of scale to reduce transportation cost, and drives the merge and alliance of liner shipping companies. Mega-sized container ships, having capacity over 10,000 TEU, were introduced, and appeared recently, in order to reduce the unit transportation cost. Korean shipping and shipbuilding companies are competitive, and have considerable market share in the global market. Even though both industries are inter-connected through ships and have many common interests in order to enlarge the global market share, inter-relation between two industries is surprisingly insignificant. In this paper current issues in the process of environmental change of marine cargo transportation are reviewed, and inter-relation of shipping and shipbuilding industries is discussed. Suggestions for inter-related development of Korean shipping and shipbuilding industries are given, and means for mutually beneficial collaboration are suggested.

코로나19 판데믹 상황에서 컨테이너선 운임은 유례없는 큰 폭의 상승세를 보이고 있다. 컨테이너선 운임 상승 요인에 대해서 다양한 분석이 이루어지고 있으나, 비정형 데이터인 텍스트 자료를 활용한 분석은 전무한 상황이다. 따라서 본 연구에서는 관련 기사들을 대상으로 최근의 컨테이너선 운임 상승의 요인들을 텍스트 마이닝 기법중 하나인 네트워크 텍스트 분석과 LDA 토픽 모델링을 통해 파악하였다. 2020년 1월부터 2021년 7월까지 로이즈리스트에 게재된 기사들을 대상으로 텍스트 분석을 하였다. 분석 결과, 중국과 미국의 무역마찰, 글로벌 생산감소를 예측한 글로벌 선사들의 급격한 기항 횟수의 감소와 임시결항의 증가, 터미널 혼잡, 수에즈 운하 봉쇄와 같은 예기치 못한 사고들이 주요 원인으로 분석되었다.

Due to the growth of container traffic and port competition, ports have increasingly been under pressure to improve their efficiency in port operation and port management for competitive edge. The purpose of this study is to compare the technical efficiency among major container terminals in China, Korea and Singapore using Data Envelopment Analysis (DEA). This paper analyses the returns-to-scale using the output orientation of VRS and CRS model. The benefits of this study examining the relative performance of container terminals will enable container terminal operating companies or port policy makers in those countries to identify current slacks and to set up a proper port management and operation plan to improve their productivity.

It has been more recent trends in container trade to make bogger ship from shipowners that many more parties concerned are getting involved. Well, it is natural to swift these situations if we have looked into container trade market in present time, which a lot of trade volumes has increased in world economy. Thus, supply side of shipping service needs to employ more capacity in the shipping market, then newbuilding may be compulsory options, that is deployment of larger ships. To cope with market situations as able shipowner, some alternatives can be also adopted, such as newbuilding, chartering and securing the space by strategic alliance. But whatever he does, shipowner has to keep in mind to prepare for the future. This is much more important factor considered to make investment decision in case of newbuilding and then he can make more efficient decision as well. However, there has been a little problems arisen due to larger ship employed on the trade route, which is linked with seaport, shipping companies and freight rates as well. Although shipowner decides to build new larger vessel as one of corporate strategic decision, there are many questions to be considered in advance. Therefore, in order to take more efficient decision, shipowner has to take into an account various situations surrounded, and then it can lead truly thoughtful decision making process.

A satellite shipping container must afford the satellite a relatively benign thermal, vibration, and particle environment that is oblivious to the extreme temperatures, sand, dust, vibrations, and shock that can accompany the transportation. Korea Aerospace Research Institute has developed a new shipping container system that will be used to transport KOMPSAT-2(Korea Multi-Purpose SATellite) from Tae-jon to launch site. (omitted)

Currently, there are very few papers that have examined the efficiency of Vietnamese ports. Of those that have, some of them take into account only a few container ports in Northern Vietnam. Others focus on comparing all types of ports in Vietnam with regard to the differences in efficiency scores when applying different methods to evaluate efficiency. However, there is no paper that specifically analyzes the efficiency of Vietnamese container ports throughout the country or that compares Vietnamese container ports with those of other countries in terms of efficiency. In order to provide more accurate and interesting information for container port authorities, in this study, 21 major Vietnamese container ports and seven major Korean container ports are selected and examined with regard to their levels of efficiency in 2016 using data envelopment analysis (DEA). This paper applies both constant return to scale (CRS) and variable return to scale (VRS) to explore the differences among overall technical efficiency, pure technical efficiency, and scale efficiency of the selected container ports. This study also indicate slacks and sets projections for inefficient ports.

A Spacecraft container must afford the satellite a relatively benign thermal, vibration, and particle environment that is oblivious to the extreme temperatures, sand, dust, vibrations and shocks that can accompany the transportation. This paper discusses the extensive yet simple vibration test and validation of one such spacecraft container used for KOMPSA T-1 spacecraft, which was transported from KARl Taejon, Korea to Vandenberg Air Force Base(VAFB) on September 30 and launched successfully December 21, 1999. The test results are presented and compared with the design requirement. The dynamic characteristics of shipping container, such as natural frequencies, satisfied the design requirement and showed that shipping container was well. designed and manufactured. This kind of know-how will help to develop the next generation of Korean space program, such as KOMPSAT-2 and Korean tele-communication satellite.

A Satellite shipping container must afford the satellite a relatively benign thermal, vibration, and particle environment that is oblivious to the extreme temperatures, sand, dust, vibrations and shocks that can accompany the transportation. In this study, we have designed a vibration isolation system of a spacecraft container that will be used to transport a satellite called KOMPSAT (KOrea Multi-Purpose SATellite) -2 from KARI (Korea Aerospace Research Institute) Taejon to its launch site. To identify the dynamic characteristics of the system, a 1/3-scaled mockup of the container was developed. A large electro-magnetic shaker (Max. 240 KN) was used to excite the mockup, and vibration signals from 20 points were collected for modal tests. Numerical simulations through CATIA 3D Modeling were performed to identify the behavior of isolation springs. The results showed that a simplified model predicts the behavior in a reasonable accuracy. Moreover, the model guides us how to design a full-scaled satellite-shipping container.

Shipping containers promote rapid development of the transport industry, and generate economic and social value. However, problems often occur due to imbalance in dynamics between exports and imports, container relocation, traffic congestion, and general shipping network designs. So, efficient and cost-effective cargo management has become crucial for the Jeju Island - Mokpo container route (JMCR) in South Korea. Dozens of recent studies reveal that collapsible or foldable containers, may become an innovative solution to problematic issues within the shipping industry. The major purpose of this study is to discuss conditions required for successful commercial application of foldable containers, based on a cost-benefit analysis precisely for the JMCR. Findings reveal usage of foldable containers can be cost-effective, if containers make a "FULL<->EMPTY" route. To the contrary, a "FULL<->FULL" route can drastically increase expenditure. However, economic analysis of actual figures for 2010-2015 indicate that benefits for Mokpo - Jeju direction are significant to cover losses on the Jeju - Mokpo line. Seasonal patterns and mixing percentages of foldable and standard containers on the route, may also produce cost-effective solutions. Sensitivity analysis reveals that benefits from using foldable containers, depend mostly on empty container shares in addition to various extra costs.
