In Korea there are Passenger ships on 106 routes running out of 10 port cities. These cities, such as Mokpo, Masan, Incheon, are the main transportation hubs the island residents today. But most passenger ship companies in Korea are limited in income and mostly small in size. These small companies have many challenges to overcome and are slow to improve services. Frequent service cancellations, aging sailors and a decline in service are contributing factors.

This study focuses on the iconography of Hindu deities in Bagan period. As a country in Southeast Asia, Myanmar received her culture from Indianized culture. As aforesaid, sailors, traders, and settlers brought with them Brahmanism and Buddhism into Myanmar. A possibility is that local chiefs or the rulers invited Brahmans to conduct coronations, weddings, and burials in Brahmanical rites as they will much impressed by the Brahmanical thoughts and beliefs. Accordingly, Brahmanic icons as objects of worship are found quite in number of places, especially in Thaton, Bago, Vesali, Sriksetra, Bagan and Kawgoon. Apart from Buddhist iconography, the Brahmanic icons of various sects can be found in Bagan. Brahmanic deities are illustrated with Buddhist painting, which is a characteristic of Baganreligious iconography. Most of the scenes on Hinduism are to be found in NatlaungKyaung, Nanpaya and Shwesandaw Pagoda. Myanmar people, however, knowingly or unknowingly ignore some features of Indian deitiesand eventually the iconsare found in various places in Bagan.

Seafarers are often placed in circumstances that require emergency evacuations due to various causes, including ship collisions, sinking, stranding, and fires. Achieving shorter evacuation time is an important factor in increasing the survival rate during these circumstances, but the narrow and complicated structure of ships is an obstacle when it comes to executing a quick evacuation. Also, unpredictable restrictions may be imposed by bad sea or weather. In this study, various experiments were conducted with sailors currently on board ships in order to examine factors that increase evacuation time. The data was then and analyzed. Evacuation time was measured by dividing crews into groups: sailors that were given an explanation of the ship's structure and those that were not. Furthermore, the visibility range was divided into 0 m, 3 m, and 5 m. The results indicated that, having an explanation of the ship structure did not have much of an effect on evacuation time but visibility conditions led to an increase in evacuation time with a maximum of 2.5 to 2.6 times longer when the visible distance was 5 m, 0 m and 3 m. Therefore, ensuring a visible distance of over 5 m was determined to be the most important factor for reducing evacuation time. In the future, effort should be made to ensure a greater visible distance to improve the survival rate of seafarers and passengers on board ships that encounter incidents.

This research examines the use of Cross Bearing in the Republic of Korea Navy. Specifically, this study focuses on the degrees of errors caused by the order of measuring targets and suggests a new method to determine Advice Course. It then reviews the appropriateness of the contents of Location Report that is regularly to the duty officer during a voyage in a narrow channel. Whenever a naval vessel passes through a narrow channel, many number of sailors are assigned to diverse positions in order to enhance navigational safety. Even though it is possible to easily recognize the location of a ship with helps of various kinds of navigational equipments using state-of-the-art technology, there are still several situations where sailors' efforts are indispensible for calculating the position of their ship : when the ship is damaged during an engagement with enemies and when the enemies interfere (GPS) signals. In addition, the particularity of naval vessels in which many number of crew members can be assigned to various positions supports for the suitability of the use of Cross Bearing in the Navy. This study will contribute to navigational safety of the ROK Navy and fostering junior naval officers' seamanship.

Objectives: This study was conducted to investigate the relationships among job stress, job satisfaction, and mental health in marine officers. Methods: The researchers gathered data on marine officers working at a harbor in Chungcheong Province, South Korea, using a self-reported questionnaire. Mental health was measured by the Symptom Checklist-90-Revision (SCL-90-R), and general characteristics including socioeconomic factors, job stress, and job satisfaction were measured by structured questionnaires. Multiple regression analysis was performed to investigate the relationships among job stress, job satisfaction, and mental health status according to the symptom dimensions of the SCL-90-R. Results: Among the marine officers, obsessive-compulsive behavior, depression, and somatization were the most problematic symptoms. Those who reported poor health, low job satisfaction, and high job stress had a higher prevalence of psychoticism, somatization, depression, anxiety, and phobic anxiety. Conclusions: An occupational health system should be introduced that would regularly check the mental health of marine officers in charge of ships and sailors, in order to help reduce their stress levels, enhance their job satisfaction, and thereby improve their mental health.

It is difficult to expect the service improvements such as increased number of sailing and making new ship due to financial difficulty this is caused by deterioration of island dwellers. In addition, the safety of ship operation is also a problem with the supply of good sailors difficult problem of low wages and lack of safety working environment. T It is necessary to ensure the introduction of public operating system in coastal passenger shipping business to secure the public and safety. There are many practical constraints but if we obtain public sea ways, it will be possible to improve the operating system through the implementation from a subsidized line and taking off business licenses of an insolvent enterprise by enhancing safety control.

Purpose: Maritime sector is fundamental to international trade; there is no doubt that seafarers have played an essential role in maritime shipping and distribution science industry. Thus, this study uses Grey models to predict the number of seafarers in Vietnam expecting to provide a range of future seafarers. Research design, data and methodology: Statistics data are adopted for numbers of seafarers by Vietnam Maritime Administration categorizing into three types: Officers at Management level, Officers at Operational level and Navigation - Engine officer cadet. Results: The results have showed that a lack of qualified seafarers in the distribution industry, which has become a global issue and Vietnam is facing challenges of providing enough supply of seafarers in the next few years. Since there has been a concern of the unbalance between demand and supply of seafarers, researches in maritime sector needs a high accuracy in forecasting the number of available qualified seafarers in Vietnam. Conclusion: This method can be applied to predict numbers of other human resources in transportation, distribution and/or logistics industries when the information is poor and insufficient. The next few years are predicted to witness a downtrend in sailors - oilers which leads to the fact that the total number of available seafarers is decreased.

The digitization of ship environments has increased the risk of cyberattacks on ships. The smartization and automation of ships are also likely to result in cyber threats. The International Maritime Organization (IMO) has discussed the establishment of regulations at the autonomous level and has revised existing agreements by dividing autonomous ships into four stages, where stages 1 and 2 are for sailors who are boarding ships while stages 3 and 4 are for those not boarding ships. In this study, the level of a smart ship was classified into LEVELs (LVs) 1 to 3 based on the autonomous levels specified by the IMO. Furthermore, a risk assessment for smart ships at various LVs in different risk scenarios was conducted The cyber threats and vulnerabilities of smart ships were analyzed by dividing them into administrative, physical, and technical security; and mitigation measures for each security area were derived. A total of 22 cyber threats were identified for the cyber asset (target system). We inferred that the higher the level of a smart ship, the greater the hyper connectivity and the remote access to operational technology systems; consequently, the greater the attack surface. Therefore, it is necessary to apply mitigation measures using technical security controls in environments with high-level smart ships.

This study investigates the conditions of Korean naval duty and combat uniforms to develop a new design. Survey participants consisted of, 723 Sailors ($25.3{\pm}6.9yr$ in age, $43{\pm}53$ months in work experience, $174{\pm}6cm$ in height, $71{\pm}9kg$ in body mass) serving in the Korean Navy for over 12 months. The questionnaire consisted of 72 questions about anthropometric characteristics, preferred design, textiles, wear mobility, and subjective perceptions. The results showed that the preferred colors for future naval duty uniforms were blue in summer (69%) and black in winter (62%). Digital camouflage pattern (60%) and darker colors on the inside of shirt collar (87%) and the edge of sleeves (84%) were preferred. They favored more than one pocket on the upper arm and chest of the shirts (58%), narrower width around pant legs and hems than the current clothing (63%), self-controlled elastic waist (55%) and no cargo type pocket on the pants (45%). There were requirements to alleviate excessive heat stress in summer and to protect from the cold and wind in winter. Wrinkle-free (85%), anti-bacterial (78%), water-proof (75%), oil-proof (90%), and elastic (67%) textiles were preferred for Korean navy uniforms. These results will be applied to develop the next generation Korean navy uniforms.
