In this study, an empirical analysis of 55 ship finance cases executed by a specific ship finance bank from 2009 to 2016 during the recession period was conducted. The purpose of this study was to find the factors affecting changes in the debt performance of Korean shipping companies. The main factors were the loan nature (investment purpose, loan-to-value (LTV), syndicated loans, loan terms, put-option, balloon, and spread), financial nature (total assets turnover, net profit-to-sales ratio, debt ratio, quick ratio, total borrowing, bonds payable to total assets, interest expenses-to-sales ratio, debt service coverage ratio (DSCR), and total assets), and the company nature (company age, chief executive officer's (CEO's) shares, and listing status). In this study, the factors affecting the debt repayment capability of domestic shipping companies (loan nature, financial nature, and company nature) were verified. The credit rating was used to measure the dependent variable, debt repayment ability. The variables of investment purpose, put-option, balloon, and spread in the loan nature, debt ratio in the financial nature, and the CEO's shares and company age in the company nature were found to be significant.

The offshore plant industry has basically functioned with a rigid teamwork culture and many operations are managed by ship's crew, shifts and affiliates together. The marine sector of offshore plant has much similarity with ship's environment. So a person who had experienced on board will have advantages to work for offshore industry. But in spite of all that, only a few korean seafarers are able to join in the offshore industry due to lack of information about the offshore environment. This study analyze the employee's wage structure, nature of employment contract, requirements of job qualifications. Therefore, this study will assist for seafarers to set up how to get their work and also suggest to develop relevant offshore training courses by researching the gap competency matrix.

Studying on the history of korean ancient poetry, we come in contact with a series of verses which 'Jejisarim's Kangho Shijo'. In the 16th century are the representative works among them. Sarim were involved in the domestic discords so that they brought about severe party strifes after all. 'Jejisarim's Kangho Shijo' profoundly dealt with the various problems concerning nature and human beings. Lee, Hyunbo and Lee, Whang are closely related with the philosophical attitudes of Confucianism. After this, Kyun, Homun and Jang, Kyungse can be largely summarized as the dual theory of reason and spirit. From the standpoint of natural principles, the epistmology of Confucianism. the theory of reason has characterized by ideality and reality. It can be said that the problem of harmonizing and uniting nature with human beings was solved in the unity of space and man. 'Jejisarim's Kangho Shijo' in the 16th century prominently express not only the courses of character cultivation but also the pride and close relationship between nature and human beings. We can say that 'Jejisarim's Kangho Shijo' in the 16th century are divided into both types of the conservative idealism and the reformative realism in the Jejisarim. Kangho Ship. the epistmology of Confucianism nature and human beings. ideality and reality political status and that such ships can be separated into types ideality and reality in the philosophical context.

This paper aims to determination of container ship's economical replacement policy by Fuzzy Annual Equivalent Cost Method Especially, though there was much vagueness to expense for calculation of container ship's economical life, this paper expressed such vague nature with a fuzzy number. And this paper developed the fuzzy expense model with a fuzzy number, and to analyze more practically than an expense model, was decided economical life-age with an application in a containership of various volumes.

When the vessel is running at the very low Froude numbers, the free-surface is difficult to be disturbed, wave-making is negligible, and the double -model velocity potential gives a very good approximation for calculating the velocity distribution just outside the boundary layer. If the speed of incident flow is gradually increased, the most perceptible change is the rise of the flow surface at stem. With further increase in speed, the nature of the flow at the bow changes completely, The flow ahead of the bow becomes more distrubed, the rise at the stem to stagnation height disappear, and the first wave crest, of less than the stagnation height, appears a small distance downstream from the stem. The present study is concerned with a small region of this flow, mainly in the bow region. The present investigation is primarily an experimental study of the flow in the bow region of s ship model, and it is undertaken in order to investigated systematically, the effect of bow geometry on this flow. The long-range objective is to use these results to guide the development of a mathematical model for predicting the flow about a ship's bow.

In Korea's ship finance, due to the nature of pro-cyclical investment, the private sector's ship finance greatly shrinks during the shipping recession, and policy financial institutions take the lead in ship finance. Meanwhile, the government established the 「Strategy for the Realization of Shipping Industry Leader」 (June 29, '2) and set a development goal by 2030 through support such as securing new high-efficiency ships. To promote financial investment. However, investment in the shipping industry is not easy to induce due to risks and uncertain market conditions. Therefore, it is necessary to review tax benefits that can induce joint investment of investors at the government level. Therefore, it is necessary to introduce a Korean version of tax lease scheme for ships in order to resolve the liquidity gap in the domestic ship finance market and successfully implement the five-year plan for reconstruction of shipping industry.

As more than 90% of global trade is carried by sea there is little doubt that the safety of the ports at which the world's trading fleet call is of critical concern. The concept of 'safe port' continues to be an area of critical concern for charterers and ship-owners. In light of increased global security and health risks the recognised principles are under security. This paper examines the nature of safe port, and analyses the precedent trend of safe port and its Implication

The mast, which is the highest structure in warships, as well as merchant ships, is mainly equipped with radars and navigation lights. Especially, due to the nature of the naval vessels that operate many communication equipment, various kinds of antennas such as communication antennas and TACAN for aircraft guiding are installed in the naval mast. In addition to the complex structure of the mast itself, the installed antenna is a factor that greatly increases the RCS. Therefore, the mast technology for reducing the RCS is being developed and applied in the United States and Europe.

Seafarers can confront to evacuate from the ship with many reasons such as collision, grounding and fire accident. It believes that evacuation time from ship is very important element in order to increase survival rate in the contingency circumstance, however narrow and complex structure of ship is one of obstacle element against prompt evacuation. Taking into consideration the unique structure of ship compared to the structure of other facilities, speed of fire propagation on board ship is faster than the same size of other type facilities. Therefore, measures to prompt evacuation are required. But it comes with the behavioral constraints of the crews and passengers of the nature of operating in a complex structure with narrow vessels. Therefore, in this study, we propose a formula to be analyzed by theoretical approach and simulation methods to improve the survival rate for the crew and passenger of the ship through the ship's structural modification. We analyzed the temperature rise and visibility which are the most influential effects on the life safety in the event of fire by using a three-dimensional analysis of sight-only program Fire Dynamic Simulator (FDS) as analytical tools.
