Tetrodotoxin is a neurotoxin produced by about 90 species of puffer fish and causes paralysis of central nervous system and peripheral nerves by blocking the movement of all monovalent cation. Ingestion of tetrodotoxin produces clinical manifestations such as paresthesias(within 10-45 min), vomiting, lightheadedness, salivation, muscle twitching, dysphagia, difficulty in speaking, convulsion and death that expressed by cardiopulmonary arrest with loss of brain stem reflex sometimes. Tetrodotoxin prevents or delays ischemia induced neuronal death by way of following 3 mechanisms. Firstly, it reduces the energy demand of the brain tissues. Secondly, it delays or even prevents anoxic depolarization. Finally, it deminishes ischemia induced cell swelling and cerebral edema. We report a case of puffer fish poisoning which presented with cardiopulmonary arrest and loss of brain stem reflex, but completely recovered by aggressive cardiopulmonary resuscitation.

In this paper, heat transfer characteristics of a self-oscillating heat pipe were experimentally investigated for the effect of inclination angle and heat loads. This type of heat pipe consists of a heating section, a cooling section and an adiabatic section. The heat pipe used has a 0.002m internal diameter, a 0.34m length in one turn and consists of 19 turns. Each of the heating and cooling section has a length of 70mm. Experiments were performed to measure the temperature distributions and the pressure variation of the heat pipe according to inclination angle. Based on the experimental results, the heat transfer ability of the self-oscillating heat pipe seems to improved with the increase of the inclination angle.

The purpose of this study is twofold. The first is to propose some remedies for the basic problems which might be induced from the present states of marketing of agricultural and marine products in Kwangju/Chonnam area. The second purpose is to justify the vitalization of conventional market system by comparing the domestic or intermediate-technology approach to the improvement of food marketing in this country with the high-technology approach originating in industrial nations. To pursue this purpose, the literary research on the above two approaches to the improvement or modernization in agricultural and marine goods marketing was followed by the empirical research on the attitude of consumer group as well as seller group about conventional markets in comparison with other markets. It leaves no room for doubt that the degree of consumer satisfaction should be included into the evaluation of marketing performance. And, consumers in sample generally perceive that they prefer conventional markets to the other types of market especially in such respects of spatial convenience, price, product quality, product variety or assortment breadth, and the ease of one stop shopping. But this is not to say that modern types of marketing institution such as supermarket can make no contribution, for this is not the case. As the result of the present study, it is suggested that high efficiency in agricultural and marine products marketing can be achieved through adopting the domestic intermediate-technology and improving the operations and business skills of conventional markets. It should be noted that since the high technology solution of the vertically integrated chain stores is one of dubious value for the problems that are latent in food marketing, alternative procedures must be sought.

This study applied a theory in cognitive psychology that human decision making should work through environmental data processing and studied the inauguration speech of Park Geun-hye as the 18th President of the Republic of Korea to explore the national administration direction by analyzing Park's cognitive system. The results of this study can be summarized as follows. First, as for national administration, President Park has established four sectoral cognition systems at large and integrated them to make a holistic system based on national development as a policy variable. Second, major policy variables recognized by President include national development, creative economy, economic prosperity, national competitiveness, economic democratization, personal capacity, cultural prosperity, and national happiness. Third, policy variables of President's cognition system form mutually dynamic circulatory relations, resulting in one policy variable. This reasonably forecasts policy consistency to a significant extent. The results of this study work as empirical evidence to clarify theories in policy psychology, enhancing further academic development.
