  • The effect of arc like streamer discharge is investigated on the hydrogen generation using the multineedle-plate electrode geometry plasma realtor(MPER) and the needle-plate electrode geometry plasma reactor(NPER). In order to restrict waves at the water surface when the high voltage applied, two kinds of the insulator such as the rectangular mesh or the hole mesh type are installed under the water surface. The discharge assistant of the two type(the saw type and the $TiO_2$ pellet type) was placed under the water surface to investigate the effect of the water surface conditions. The experimental results are compared in case of the reactor with and without the discharge assistant on the water surface.

  • This study has been performed to review critical issues affecting continuous residence in profit(self-paid) assistant living facilities for the elderly in the United States. There are three factors influencing continuous residence of frail elderly in the facilities as long as they want without involuntary discharge : Financial ability, behavioral aspects, and facility management situation. Regarding financial ability, income, purchase of insurance policy, cashable assets, willingfulness to pay, and health status were found to be crucial determinants of continuous residence. Overall, 40-50% of those aged 65+ are financially able to stay in the assistant facilities as long as they want, without involuntary discharge. As for behavioral aspects, extroversions, congeniality, culture & life style, conscientiousness, preference for person, and physiological habits were found to be crucial determinants of continuous residence. As for the management situation, it is essential that facilities reach nature level of self-governing rights of the older residents and good local images, and conflicts among the residents and managing parties be resolved on the agreeable standards of inspectors. finally in this study, it is proposed that in Korea, national pension authority offer a liability package for assistant residence, for the case of individual bankruptcy.

  • A method is presented which enables easily the computation of the suspended sediment discharge as the mean sediment concentration and mean flow velocity. This method has significant advantages over the traditional method, which principally depend on a set of measured concentration data. The method is based on both a new sediment concentration and mean sediment concentration equations which have been derived from the entropy concept used in statistical mechanics and information theory: (1) The sediment concentration distribution equations derived, are capable of describing the variation of the concentration in the vertical direction. (2) The mean concentration equation derived, is capable of calculating easily the mean concentration by using only one measured concentration in open channel. The present study mainly addresses the following two subjects : (1) new sediment concentration and mean sediment concentration equations are derived from the entropy concept : (2) An efficient and useful method of suspended sediment-discharge measurements is developed which can facilitate the estimation of suspended sediment-discharge in open channel. Flume and laboratory data are used to carry out the research task outlined above. An efficient method for determining the suspended sediment-discharge in the open channel has been developed. The method presented also is efficient and applicable in estimating the sediment transport in rivers and the sediment deposit in the reservoirs, and can drastically reduce the time and cost of sediment measurements.

  • To estimate the peak discharge from the small rural watersheds, 53 storm events of seven small watersheds from 1972 to 1989 were selected and were analyzed by the multiple regression technique. The peak values by the new prediction method developed in this study were also compared to the real data of Banwol Basins and the estimated peaks of the several watersheds which were analyzed by the Korean engineering companies. These values were also compared to the results from the other method, i.e. the Rational Method, the Kajiyama Method, the Nakayasu Unit Hydrograph companies. Through Method, the Area Routing Method, etc., which are favored by the Korean engineering companies. Through these comparisons, it is proved that the proposed method may be used for day-to-day use without any problem. However, there should be some modifications and improvements as more data are available in the future.

  • Objectives : DAMA cases were analyzed to examine what the main casual factors of DAMA were and how to deal with these cases effectively in hospital with the DAMA interdisciplinary team including medical social worker whose role is to perform psycho-social assessment, family counsel, to evaluate family's DAMA need. Patients and Methods : The content analysis of medical record and social work record were reviewed in 37 cases referred by medical doctor to DAMA team. These cases were reported by patients' self discharge request or family's request for discharge from September 1998 to February 2000. The DAMA team consists of Assistant Director of Hospital as team leader, medical staff in-charge, social worker, QI nurse, other staff members who are not involved in direct treatment for patient, and administrative clerk. Results : The results of content analysis are as follows : 1) The most causal factors of DAMA consist of combination of more than 2 factors. 2) The major decision-maker is revealed to be son and daughter of patient. 3) In 59.4% of cases, family was not informed of patients' prognosis, alternatives, the consequence of DAMA at all. 4) In cases of DAMA report, the rapid intervention of social worker is carried out. Conclusion : In this study, we propose the interdisciplinary team approach to make decision legitimately and ethically for DAMA. The suggestions from this study are as follows : 1) To deal with DAMA case properly, the interdisciplinary team approach should be considered. 2) The criteria for DAMA case should be formed carefully. For the explicit selection of DAMA case, preliminary system for high-risk patient screening is recommended. 3) The medical social worker is available for the psycho-social problems of the patient once family members. For the effective family counselling, discharge planning and nursing home placement, the participation of medical social worker should be mandatory.

  • This study is aimed at understanding the factors affecting rehospitalization of a tuberculosis patient. In a public hospital with a tuberculosis ward in Seoul, the data of 360 patients who discharged the hospital from July 1, 2012 to December 31, 2012. Data was selected from 'nursing information survey' or 'discharge analysis DB' of the department of medical records. The possibility of rehospitalization was higher in the group with those who has no job, those with medical care assistant than with health insurance, drinks about 10 times a month, personally came to the hospital, main guardian is the patient's spouse, have discharged from hospital against the doctor's advise, and principle diagnosis is not a pulmonary tuberculosis but the other respiratory disease. Therefore, it is expected that the possibility of rehospitalization would be effectively reduced if an intensive intervention is taken on the first hospitalized patients who have the features described above.

  • According to the regulation of IMO, oil discharge from ships is allowed under 15ppm only and an oil filtering equipment is essential. However, for large ships using heavy fuel oil of over S.G 0.98 and viscosity 380cSt and system oil, it has been in difficulty to process with existing filtering type of oily water separator. A parallel plate type oily water separator which is one of gravity type separators can be used as an assistant equipment for the oil filtering system to meet the present IMO standard of 15 ppm, because it is an efficient method in dealing with a large amount of rich oil with high specific gravity. This work is focused on the fundamental investigation of the performance of the plate type oily water separator by visualization method and PIV(Particle Image Velocimetry) measurement to acquire multi-point velocity data simultaneously. The experimental results showed that the space of the plates acts a significant role in separating process and it was found that an important point to minimize a vortex flow is to flow a large amount of fluid in space of the plates in order to promote the efficiency of separation.
