Conceptually, the emergency is classified as an urgency and an emergency. The Urgency is not immediately life threatening, but could become so if not resolved promptly. So, it requires prompt patient care same as in the emergency situation. However, the emergency is immediately life threatening and requires immediate action, such as calling 119 and basic life support. Most medical emergencies in the dental clinic cases are urgencies. The incidence of true emergencies is approximately 1/1,000,000. Adequate managing medical urgencies are important because the chance of encountering medical emergencies in the dental clinic is high and higher these days especially because of rapidly aging Korean society. Many dentists indicate that many dentists feel difficulties to recognize and treat medical problems. This paper reviews the concept of medical emergencies and how to cope with commonly occurring urgencies in the dental clinic such as loss of consciousness, hypoglycemia, hyperventilation syndrome. The best treatment for medical urgencies and emergencies in the dental clinic is prevention. Also, it is required to make preparation for emergency situations such as CPR education for dentists and being well-acquainted with equipment and drugs for the emergency care as well as to systemic medical evaluation, patient monitoring, and sedations for controlling patient's anxiety and pain. In this paper, simple algorithms based on guidelines for common urgencies in the dental clinic are suggested. In conclusion, every dentist has competencies to do the urgency care adequately and basic life support. Also, advanced cardiac life support is strongly recommended when sedation is performed in the clinic.

The present situation of Korea already shone various symptoms of the aged society, and many kinds of data reported by the National Statistical Office demonstrate those facts. However, to my regret, sufficient efforts for aged workers are not taken in the area of industrial safety. In this research, work arrangement and industrial accidents of middle-aged and aged workers over last 5 years were analyzed. According to research results, proportion of industrial accidents involved middle-aged and aged workers was as high as 40%, and that of aged workers alone was so high as 25%. In addition, proportion of accidents were higher than that of worker population f3r aged wetters. Considering ages, it was demonstrated that as workers get older, mean number of accidents shows the tendency of going higher, and that as years go by, mean lost work-days are increasing regardless of age group. Main accident types were Fall followed by Slip, and Work-Related Disease, furthermore proportion of Slip was highest than any other types for aged workers. Based upon these results, it was emphasized thai careful attention should be paid to functional characteristics of aged workers, and that modification of accident prevention policy would be necessary.

In addition to the instability of energy import costs caused by the depletion of petroleum resources, which is a representative energy resource, and the strengthening of various regulations such as the convention on climate change, the plant for bio energy production, which is being watched as the next generation energy, and became subject of various complaints. In order to solve this problem, the bio-plant is underground and the ground is parked, making the convenience and accessibility of citizens more and more accessible. In this situation, the development of bioenergy production technology also increases the risk factor in bioenergy production process. Accordingly this paper explains method about apply the wide angle camera based AOA algorithm to the bio plant to prevent the accidents from spreading due to the lack of facilities and safety devices and the aging of the facilities and suggests a technique that can quickly identify the location and direction when it occurs.

The Korean fisheries industry is a traditional business, the majority of which are small and medium-sized enterprises (SMEs). It has played an important role in the South Korean economies in the past several decades, but it currently faces the limitations of growth potential and profitability due to declining workforce, aging populations, deteriorating fishery environments, climate changes, and rapid changes in the global industrial ecosystem. Many studies have suggested solutions for the fisheries industry in macro perspective, but there are rarely any studies taking the strategic approaches for the problem. If it is possible for governments to support the companies that are likely to increase their value-added selectively, it will break through the current situation more effectively. This paper introduces a study on the selection method utilizing data envelopment analysis (DEA) to find SMEs with potentials to increase profits and growth. We suggest selecting SMEs with high management efficiency and ability to utilize intangible assets as the target companies. We also suggest policy objectives for SMEs in the domestic fisheries industry based on the results of DEA analysis and propose a data-based method for the policy decisions.

Many electrical socket-outlet fire accidents take place not only in homes but in the offices each year. The causes are mostly faulty constructions, managerial problems and carelessness. Construction and managerial flaws can be resolved by regular or special inspections, but carelessness is not solvable through inspections. Such carelessness can be related to the consumption capacity of electrical socket-outlets presently, the rated current of electrical socket-outlets is based on 16A. However, even at 16A, the heat generated in the insulator of an electrical socket-outlet varies due to such factors as part damage and environmental conditions of use. To explore this situation, the study conducted an experiment to analyze thermal relationship by applying 10A, 20A, and 30A currents. To secure reliability, the study employed thermal analysis simulation and compared the thermal relationship in the same current value. The experimental and simulation values were found to be similar and therefore, diverse current values were replaced with the simulation. At 30A, the temperature was found to rise to at least $169.9^{\circ}C$ which had worked as a sufficient amount of energy to bring the insulation aging of insulator.

It is our imminent project that we should train young and able manpower to strengthen the international competitiveness under the free trade of agricultural products, to solve the problem of decrease in farm population and of aging people in agriculture. The objective of this research is to suggest an alternative policy plan through the survey and analysis on the controversial issues in loans for starting agricultural business based on the survey of graduates of Korea National Agricultural College from 2002 to 2005. According to the survey, in case of graduates who are not available sufficient fanning capital such as land and agricultural facilities on it, they are not able to get loans from banks in that situation. The survey, as a result, points out that those who are legally required to do farming should be given several special aids by the government such as the improvement of Credit Guarantee Fund System for Farmers and Fishermen and the farming loans conditions for initial farm business, a long term lease of public land, giving a priority in lease-farmland project of farmland bank and allowing loan for working capital for farm management.
