In this paper, I have developed an automatic distress notification system (ADNS) working with an external VHF device in small ship. The proposed system is as part of a small ship disaster analysis system which can detect and quickly respond to the small ship disaster. The automatic notification system receives the location information signal from the disaster analysis system, and the signal will be converted into voice signal to broadcast of the accident position through external VHF device. It will be sending a distress message as form of voice information through VHF device until sinking under the water. Through this research, I expect we'll be make a quick response and prevent a terrible loss of human life.

This study investigates the interactive effects of guilt appeal level and empathic disposition (personal distress/empathic concern) on responses over the international relief messages. Guilt appeal level refers to the high or low degree of a message eliciting guilty feeling from the recipient. Empathic disposition is defined as personal tendency to assimilate and concern about the experience of others and we used two sub-dimensions, empathic concern and personal distress. The experiment was composed of two steps. At the first step, the participants rated the personal disposition measures and at the second step, they were shown one of the relief messages with different guilt level. Thus, the whole experiment was guilt appeal level ${\times}$ personal traits factorial design on guilty feeling, attitudes and behavioral intention. The results showed that guilt appeal level interacted with the personal distress disposition on the responses. The interaction was induced mainly from the differences of personal distress in the condition of high guilt appeal. High empathic concern individuals showed more favorable attitudes and behavioral intention regardless of the appeal conditions compared to low empathic concern individuals.

This study is implementation of transmitter signal processing of MF/HF DSC Controller, obliligation system of GMDSS, focused on the technique of processing to encode the distress and general signal of the DSC message. We analyzed recommendation which prescribed frequencies, operational procedures and technical sequence of the DSC and suggested the basic circuit to be materialize the function of a distress alert and general calf of the DSC equipment using Microprocessor, constructed the algorithm of processing a message, programmed it using C language.

A way to increase effectiveness of charitable donation ads is to activate or magnify emotional experiences (e.g., sympathy, empathy, psychological distress) among target audience. Past studies suggest that mental imagery and attention, which activate or magnify emotional experiences, can be influenced by verbal message attributes (i.e., message concreteness and valence) of charitable donation advertisements. Based on the previous research, the study built a conceptual framework for processing of charitable donation advertising: message concreteness and valence ${\rightarrow}$ mental imagery and attention ${\rightarrow}$ emotional experiences ${\rightarrow}$ donation intention. To verify the framework, the study investigated on the influence of message concreteness and valence on mental imagery and attention through assessing ERP responses. It also examined how message concreteness and valence have an effect on the intent to donate through measuring the amount of donation. The study revealed that concrete message activated mental imagery more than abstract message whereas negative message enhanced attentional level more than positive message. Compared to the other conditions, when the message was concrete and negative, the amount of donation was significantly large.

The fact that the gigantic and luxurious cruise, Titanic, sank into the cold winter sea causing 1,490 casualties in 1912 resulted in discussing safety of life at sea international and Korea has adopted and operated the GMDSS to keep up with those international endeavors to decrease the number of tragic accidents at sea, However, all GMDSS equipment is making a monotonous beep sound when receiving a distress, emergency, safety and even general message so that it might contribute to lowering ship operators' cognitive abilities as well as being dull of safety precautions. So, I'd like to render great services for saving even one person by considering developing an automatic audio alarm device which allows people to respond in a prompt manner as soon as they hear an audion alarm such as a shipwreck.

The international COSPAS-SARSAT program is a satellite-based search and rescue distress alert detection and information distribution system and best known as the system that detects and locates emergency beacons activated by aircraft, ships and so on. However, the current message format of the system is not encrypted so that, if the rescue signal can be intercepted by the unintended receivers, the subsequent rescue activities can be handled in a hostile environment. So, this article concerns how to deal with the rescue signals in a secure way and proposes some adequate encryption methods and the corresponding key management.

In the reality that the fishing population is decreasing and the single-man fishing vessels is increasing, mandatory equipment for navigation and radio equipments for the safety of fishing boats has continued to be added. Therefore, many equipment such as navigation, communication and fishing are installed in the narrow steering room, so it is very confusing and a number of monitors are placed in the front, which is a factor that degrades the function of maritime observation. To solve this problem, we studied an interface that integrates and operates to major radio facilities such as very high frequency-digital selective calling equipment (VHF-DSC), automatic identification system (AIS) and fishing boat location transmission device (V-pass) into one multi function display (MFD) based on LAN. In addition, IEC61162-450 UDP packets and IEC61162 sentence were applied to exchange data through link between MFD and radio equipments, and additional messages needed for each equipment and function were defined. The integrated MFD monitor is easily operated by the menu method, and the performance of the interface was evaluated by checking the distress and emergency communication functions related to maritime safety and the message transmission status by equipment.
