Pilots have used checklist as a valuable tool to improve aviation safety and to reduce human error. A checklist however is too complex for a student pilot to use with less flight experience or time than a commercial pilot. It is agreed upon such complex checklist be a factor to threaten aviation safety for student pilots. This paper has focused on a checklist by dividing it into a couple of basic three flight procedures. Making exploratory case study of student pilots, researchers could analyze the correlation between checklist factors and those of human errors. First of all, it was necessary for student pilots to be educated professional knowledge regarding aircraft structures and engines to perform preflight inspection reducing human errors. Moreover it was recommended student pilots as well as maintenance crew confirm checklist together to enhance aviation safety.

In this paper, PLC which can be installed easily and is stable to transfer datum, is tested for approving its application in a real ship. Internet access service, CCTV monitoring, light control and huge sensor communications are needed for enhancing the convenience and safety of passengers and crew in ships. In order to apply PLC in ships, we surveyed some noises interrupting PLC in ships and investigated the PLC characteristics. The Hannara, a training ship of Korea Maritime University, was used for the test. We measured and analyzed blocking noises using by NI's SCXI-1001. When noises of specific frequency band occurred near the PLC frequency band, PLC transfer capacity was low for mass datum. We developed and verified some methods to apply PLC in a ship under lots of noises.

Maritime University cadets must be on board ship's after thoroughly completing a Basic Safety Training Course. During their spare semester they must complete basic principle of the course and then, attend to both Advanced Safety Training Course and Tankers Training Course before they graduate. However, all cadets are exposed to risks during their onboard training. It means that most of commercial ships have to train them before boarding and perform duties according to all sorts of check lists based on the ISM. Accordingly, this research will deal with the treatment for toxic chemicals which is not fully covered by shipping firms, vessels and even a Maritime University for cadets. The lack of pre-knowledge about it is considerably hazardous to the cadets who have no onboard experience. As stated above, the majority of the onboard cadets board their ships without previous training on treatment and knowledge for toxic chemicals. As a result, there are some cases that cadets are injured due to the lack of knowledge to treat toxic chemicals and due to carelessness. Furthermore, they end up leaving a ship prematurely. To prevent these incidents from occurring, this paper recommends thorough training before going onboard provided by Maritime University, the systematic database on the safety of the toxic chemicals and the development of the online contents for safety education of toxic chemicals fitted on each ship's types are necessary to avoid risks and accidents onboard. Furthermore, it is suggested that shipping companies should manage the ship according to the safety check list on toxic chemicals and the crew in charge with qualification for the treatment of toxic chemicals should provide a safety education and supervision.

Urinalyses have been conducted for 28 seamen in K University's training ship and Creatine and Uric acid turned out to be higher in all ages, which can be inferred that on-deck environment has caused negative impact on kidney and/or malfunction. In addition, TC arid HDL-C, LDL-C has decreased, however, TG has increased after the navigation. All different positions including oater, crew, decker, engineer and radio part showed the similar pattern. TC and HDL-C has decreased in 30s, 40s and TG has increased in 30s. A few of the 30's show extremely high TG rates so Hyperlipidemia is suspected. 7 members fumed out positive for UBG test and 5 positive for PRO test. Especially there was only one UBG positive before the navigation but, 7 members has become positive, which means the one-month ocean navigation has definite impact on the liver cell function.

This study examined the current status of the number of ships and marine officers in the coastal shipping in order to successfully solve the problem of the shortage of manpower. Then it forecast the number of costal ships by ship size and the demand of coastal marine officers by applying the crew quota of the Ship Personnel Act. In addition, The supply of manpower was predicted using the Markov model, reflecting the number of turnover and retirements by year, as well as the number of new entrants and incomer from ocean-going shipping. As a result of forecasts, the demand for coastal marine officers is forecast to increase from 6,057 in 2023 to 7,079 in 2030, and the supply is forecast to decrease from 5,771 in 2023 to 5,130 in 2030, showing that the manpower of shortage is worsening. This study analyzed the problem of the shortage of lower-level licensed coastal marine officers and objectively forecast the demand and supply of manpower through quantitative analysis. In order to resolve the manpower shortage, it was proposed to expand the training and supply of 5th and 6th grade low-level licensed coastal marine officers. This study will be able to provide useful data to solve the problem of shortage of manpower for coastal shipping.

Loss of Control in Flight(LOC-I) due to aircraft upset attitude has the highest air accident rate, and International Aviation Institute such as ICAO and FAA recommended flight crew to operate aircraft safely through UPRT(Upset Prevention & Recovery Training) program. ICAO has selected Loss of Control(LOC) as key safety indicator, and recommended to respond using TEM(Threat and Error Management). However there are not much specific treats and errors classified for UPRT programs using real TEM based on evidences. This study intends to consider the importance of UPRT through the introduction of UPRT and accident analysis using TEM. Typical upset accidents were classified to common threats as IFR, inadequate training, Automation surprise, and inexperienced copilots. The common errors were cross-check, speed and altitude deviation, callouts, communication, thrust and stall action fail. The undesired aircraft states were inadequate automation mode, Deviation of speed and vertical, stall, and crash. These suggest areas to improve UPRT.

Advanced Life Support Systems (ALSS) are being studied to support human life during long-duration space missions. ALSS can be categorized into four subsystems: Crew, Biomass Production, Food Processing and Nutrition, Waste Processing and Resource Recovery. The System Studies and Modeling (SSM) team of New Jersey-NASA Specialized Center of Research and Training (NJ-NSCORT) has facilitated and conducted analyses of ALSS to address systems level issues. The underlying concept of the SSM work is to enable the effective utilization of information to aid in planning, analysis, design, management, and operation of ALSS and their components. Analytical tools and computer models for ALSS analyses have been developed and implemented for value-added information processing. The results of analyses have been delivered through the Internet for effective communication within the advanced life support (ALS) community. Several modeling paradigms have been explored by developing tools for use in systems analysis. They include object-oriented approach for top-level models, procedural approach for process-level models, and application of commercially available modeling tools such as MATLAB$\^$(R)//Simulink$\^$(R)/. Every paradigm has its particular applicability for the purpose of modeling work. An overview is presented of the systems studies and modeling work conducted by the NJ-NSCORT SSM team in its efforts to provide systems analysis capabilities to the ALS community. The experience gained and the analytical tools developed from this work can be extended to solving problems encountered in general agriculture.
