Dental prosthetic restoration shows a big difference of cost per itemized unit depending on the size of dental labs, facility standard, manpower, and performance. Even the same dental labs have distinctive cost according to manufacturing performance, inflation, and the number of workers. However, in spite of such a change of circumstances, it appears to be quite stable in the relative cost per itemized unit unless the manufacturing trend of particular item changes dramatically. Therefore, if the relative number of cost per itemized unit, which is produced by costing, is indicated, we are able to utilize it effectively as a standard wage estimate. If the wage of dental prosthetic restoration is determined on the basis of cost, it is desirable that the relative value of cost and that of wage are identical. But, by means of comparative analysis, since the relative value of wage reveals mostly lower than that of cost depending on an item, it is considered that the wage is not reflecting the cost appropriately. Due to the subdivision and the profession of medical technology, the new development of wage items for dental prosthetic restoration is required. This means that the need for the establishment of new wage items should be presented as the general concept of dental prosthetic restoration changes and the level of pathologic technology increases. The current wage structure has differences in the degree of difficulty according to unit items and in the cost factors. Nevertheless, the differences are not reflected enough to the wage, so there is a potential to lower the medical quality through the use of low-price materials to avoid the increase of cost and the work process which skips a manufacturing step. The new items of dental prosthetic restoration also increases, but the development of proper numerical value system is not supported. Thus, the right price is set mostly by applying to the wage of a similar item. Since most wages are established by an individual agreement between the dental clinic institute and the dental labs, the propriety of wage level lacks. Therefore, it is urgent to provide and promote the system of a fair work charge by a standard cost which can be applied to all medical institute.

The improvement of a living standard as the result of economy growth along with overpopulation in metropolis has generated various forms of food waste. Restaurants and households are considered the main cause for the problem. The food waste engenders many headaches like the waste of food resource and the conflict of waste processing. The government felt a limitation to the reclamation in this small land, and 40% of food waste out of all the wastes brought out a sediment and nasty smell. therefore, the government announced a policy that calls for no reclamation without managing food waste in advance. In response to this flow of change, Daegu city needs to do as follow : 1. Establish plans to make food waste resourceful. 2. Seek the objectives and ways of accomplishment for the utility of food waste. 3. Recycle food waste systematically. 4. Use food waste as fodder, manure, and byproduct. The problem of food waste can not be solved by government only. Government and academic circles should make an effort to develop technologies for the better use of food waste, and people should help government to work out its policy. No matter how we work hard, we can not reduce food waste completely and make it 100% resourceful. After all, in reclaiming or incinerating the understanding of people and a group of civil organizations is required.

In the postal delivery service, both the standardization of business process and the workload measurement is very important part of saving the cost and improving the efficiency. However, these are not easy to apply to real situation because of the labor-intensive and diversification of delivery environment. In this study, we develop the methodology for the standardization of business process and workload measurement model of the postal delivery service. Firstly, we introduce the work factor analysis on the postal delivery process. Then, we propose the methodology workload measurement model based on diversification of delivery environment.

The study is to find out substantial influences on customer satisfaction with the patients in the five hospitals in Daegu metropolitan city. As for the factors of the influences, the study made an analysis on the environment of hospital facilities, quality of medical treatment, kindness of doctors and staff, and the evaluation of hospital in general. The patients as customers rated the environment of hospital facilities to be satisfactory, but they showed a negative response to the hospital management. The quality of medical service and the kindness of doctors turned out to be relatively satisfactory. However, waiting time for medical procedures or medical examinations took long from 10 minutes to 30 minutes. Outpatients reacted negatively in the kindness of staff by not responding, but accessed positively in the satisfaction of overall medical service. In terms of the services that hospitals offer, the participants rated good in spite of the fact that some did not respond. The kindness of staff needed to improve through education. The factors that affect satisfaction of hospital customers, that is, patients, make forceful management avoid in the recent medical business. Since it is obvious that hospitals win collapse without customer satisfaction, the study regarding effective management needs to be continuous and its result should be reflected in the hospital management. For the improvement of customer satisfaction, first, all the staff's mind and behavior need to change through a regular evaluation from a medical institution. Second, a survey. on customer satisfaction and subsequent education need to follow for the enhancement of medical quality and kindness. Third, motivating for customer management, holding a conference, and prizing for its good result also need to follow. Finally, it is important to remember that it takes a great deal of time and effort as we11 as consistent willingness by chief executive officers of the hospitals.

Meconium is a strong inactivator of pulmonary surfactant. The deficiency of surfactant or surfactant dysfunction may contribute to respiratory failure in a wide group of disorders, including meconium aspiration syndrome (MAS). We reviewed the effect of pulmonary surfactant therapy for severe MAS in ours as well as other countries. In general, surfactant therapy improves pulmonary oxygenation (oxygenation index or arterial/alveolar oxygen tension) and reduces the requirement for ventilation, and oxygen supplementation or hospitalization time. However,its effects on mortality and pulmonary or extrapulmonary complications are variable. In Korean studies, outborn infants are five times more common than inborn infants; therefore, the initial hospital care at delivery including adequate tracheal suctioning is important to improve the outcome of patients with severe MAS. To confirm the effect of surfactant therapy in MAS, additional well-designed,multicenter, randomized, controlled trials are needed. In addition, determining the optimal type of surfactant therapy (bolus, lavage, or combined) and the appropriate dose and duration of therapy is important.
