This study was performed to examine the factors influenced on the decomposition of nondegradable organic pollutants( Tricholoroethylene,Benzene ) in aqueous by ultrasonic irradiation. The TCE( Tricholoroethylene ) and Benzene are major hazard compounds causing environmental Pollution and not decomposable substances by conventional treatment. The results shows that the oxidation and reduction reaction of ultrasonic Irradiation was formed the H$_{2}$O$_{2}$ , H$^{+}$ and OH$^{-}$ radical, and then theses was decomposed pollutants of TCE and Benzene in aqueous. We were conformed that the ultrasonic irradiation was excellent in removal efficiency of the nondegradable organic substances any other than processes and utilized the treatment of organic compounds in the industrial wastewater. Conclusively, these results suggest that ultrasonic irradiation may be extremely useful for the treatment of wastewater contaminated organic pollutants, which is difficult to treat economically by conventional treatment.

This study was performed to examine factors affecting the decompostion of nondegradable polluants(trichloroethylene(TCE), phenol) using ultrasonic irradiation. The TCE and phenol, which are major hazard compounds causing environmental pollution, were not decomposable pollutants by conventional treatment. The results show that the oxidation and reduction reaction of ultrasound produced $H_2O_2$, $H^+$ and $OH^-$ radical, which decomposed pollutants of TCE and phenol in water. It was confirmed that the ultrasonic irradiation showed an excellent removal efficiency for the nondegradable pollutants than any other processes, utilized in the treatment of organic compounds in the industrial wastewater. Conclusively, these results suggest that ultrasonic irradiation may be highly useful for the treatment of wastewaters contaminated organic pollutants, which is difficult to treat economically by conventional process.

Phenol is the most common and abundant pollutants in the refractory substances and this is difficult to be degradable by conventional methods. Therefore, a considerable interest has been devoted to developing new process where phenol can be easily decomposed. In this study, the series of ultrasonic irradiation for removal of phenol has been selected as a model reaction in the batch reactor system in order to obtain the basic data investigate the influence of various experimental parameters such as concentration, pH, reaction temperature, acoustic intensity. The products obtained from the ultrasonic irradiation were analysed by GC/MS and UV spectroscopy. The formation of H₂O₂, a well-known the strong oxidant was found proportionally to increase with irradiation time. The intermediates of ultrasonic irradiation of phenol were identified as H₂, CO₂, Catechol, Hydroquinone, and p-Benzoquinone. As the decomposition of phenol proceeds by the ultrasonic irradiation, the pH of phenol containing aqueous solution increases slowly. The decomposition of phenol was found to be occured fast in the basic medium. In general, the rate of reaction is proportional to the reaction temperature obeying the Arrhenius' law. However, in the ultrasonic irradiation, this suggests as the reaction temperature increase the decomposition rate of the reactant decreases. This result meant that the increase of reaction temperature due to the increase of vapor pressure of water accelerated the decrease of acoustic intensity which was can be proportional to the decomposition rate of these compounds. It was found that more than 80% of phenol solution was removed within 2 hours in all reaction conditions. The reaction order in the degradation of the phenol confounds was verified as the pseudo-first order. From the fore-mentioned results, it can be concluded that the refractory organic compounds as phenol could be removed by the ultrasonic irradiation with radicals, such as H· and OH·radical causing the high increase of pressure and temperature. Finally, it appeared that the technology using ultrasonic irradiation can be applied to the treatment of refractory substances which are difficult to be decomposed by the conventional methods.

골프 산업의 전망과 과제

Because of the increase of public needs for golf, the golf becomes more and more popular sport in korea. In spite of the public needs, it is difficult to find governmental supports and counterpropsals for the golf industry. In order to make an overall development of golf industry, intensive considerations are needed. First, it is requested that a elastic taxation system must be laid to each golf course. Second, Government makes the active support system for domestic golf equipments industy to raise its competitive price and market power. Third, so as to improve its competition power, it is important to establish a cultivate system produce a large number of capable instructors. Lastly, the professional sports management agents are crucial to induce recent sports marketing techniques in golf.

The purpose of this paper is to investigate the generation rate, treatment and the problems of medical wastes based on the papers, government published magazines and concerned with books and papers. The results were as follows : 1. The generation rate of infectious waste in 1993 was 5,201ton/year and then the syringe and gauze was 4,990ton/year(94%). the tissues of patients was 311ton/year(6%). And the figure has been increased about 19.5% in a year in comparison with about 3.9% in U.S.A. This result was about 5times as high as that of a foreign country. 2. The range of infectious waste was accurately determined on the medical wastes and then the separating collection of this wastes had been conducted in regular. It was important that the sources of infectious waste was detailedly investigated. 3. The treatment methods of medical wastes were mainly incineration and the other those were recycling and landfill. The medical waste generated in hospitals (about 60%) was treated in the offsite incineration under contract by private companies and the rest of those (about 40%) was treated in the own incineration of hospitals. But this facilities were unsuitable on the teatment of infectious waste in aspect of air pollution protection. 4. In the point of problems in medical for the protection of infection from the medical wastes, the separated basket for infectious waste should be prepared, the BHS and double package should be used in hospital. 5. Above all, it was important was that the management and control system of medical wastes should be improved in hospital management. For example, the manifest system for the management of medical wastes was reguired.

The purpose of this study is to analyze organizational climate and job satisfaction of physical education teachers in secondary schools. This study will look at correlation factors and the relationship between organizational climate and job satisfaction. The major findings of the study are as follows. First, Physical education teachers compared to Korean, English and math teachers are more positive and progressive in the personal interaction of members in the organization and enthusiastical in reaching the goal of the organization. And they are also sensitive to their works. Second, Physical education teachers are more satisfied when the school director is able to guide and lead the organization and its members. School directors who are able to create and maintain high office morale are also favoured.
