The purpose of this study was to determine the marginal fit of recasting by used nickel-chromium metal alloys, Hi-Crown, New-Crown and CB-80. Ninety crown prosthetics were divided into eighteen groups according to new to old metal ratios. Each crown was seated on its master die and then the marginal gaps were measured under optical microscope($\times$50). All groups were showed good marginal fit, except group 3 of Hi-Crown(156$\mu$m). The results suggest that the marginal fit of Ni-Cr metal alloy casting bodies were good as without concerned to mixed ratios and metals.

The number of disputes between physicians and patients caused by medical malpractice are showing a sharp increasing over the past several years. The disputes on medical malpractice may be resolved either in court or by direct negotiation between both sides concerned. There are no special acts relating to the civil or penal liability of the physicians in Korea. The medical disputes are decided merely through legal technicalities and without reference to actual medical practice. The current system which does not compensate injured patients adequately or equitably leads to taking a long time consuming for dispute resolution processes. The things make worsed, the problem is due to not being of insurance system or a proper funds for compensation. This research proposes a outline of new and comprehensive alternative for these problems and failure of conventional resolution of medical disputes. So far, we have learned lessons from the excperiencies of resolving medical malpractice disputes of Japan and the United States. The proposal first calls for an administrative arbitration and pretrial screening panels as a condition precedent to trial. The proposal also includes to facilitate with the funds for compensating the injured.

This paper is to show the history and the brief present situation, the further vision and the considerations of Vojta physical therapy. Since Vojta therapy has been introduced into Korea in 1980, the workshop had the total 7 times and has produced 76 Vojta physical therapist during the past 15 year. But Vojta thrapist members have a gradually declining tendency in the present state. The counterplans for the considerations as follows; 1) Physician and Vojta therapist must be concerned about the growth of Vojta diagnosis and therapy. 2) As the medical examination and treatment system's establishment, an early infant's tretment will be performed. 3) The course of workshop in Korea must be admitted to be a regular qualification by the Vojta center of Germany. 4) Cerebral palsy treatment need home care system by Vojta therapist. 5) Vojta therapist has to reside in a public health center.

Through this study we have reviewed the implementation model, certificate criteria and the formation of KOSHA 18001 Safety and Health Management System and have compared and examined with OHSAS 18001 Certificate. In the course of the 1st questionnaires which have been participated by the concerned Safety and Health Staffs(such as Project Mannager, Site Supervisior, Safety Engineers) of the local construction sites, actual condition of application for KOSHA 18001 has been scrutinized and examined. And as a result, we presented the improved model by digging out the problems. The improved model has been applied for about eight months in local construction sites and the effectiveness has been carefully compared and examined before and after the application of the improvement model through the 2nd questionnaires by the relevant staffs (such as Project Manager, Site Supervisor, Safety Engineer and Project Engineers of the Coordinated Sub-Contractors).

In materials science, one of the new concerns in the construction industry, it is well established that mineral dust from rocks (stones) has adverse effects on human health. For instance, it is suspected that some mineral dusts in particular leads to occupational diseases, including lung cancer. The present research concerned the relationship between cancer and those workers who work in Turkish construction industry and quarries and are exposed to silica mineral dust from natural stones. One focus was cancer prevention methods applied in-site. In mining and construction industry where stone dust is widely used, silicosis induced lung cancer is frequently seen. Cancer cases which are seen across the regions mostly affected by silica containing dust in Turkey were identified and a survey was conducted of the methods to protect workers in the construction industry from exposure to silica dust.

The choice of input distribution in quantitative risk assessments modeling is of great importance to get unbiased overall estimates, although it is difficult to characterize them in situations where data available are too sparse or small. The present study is particularly concerned with accommodation of uncertainties commonly encountered in the practice of modeling. The authors applied parametric and non-parametric bootstrap simulation methods which consist of re-sampling with replacement, in together with the classical Student-t statistics based on the normal distribution. The implications of these methods were demonstrated through an empirical analysis of trade volume from the amount of chicken and pork meat imported to Korea during the period of 1998-2005. The results of bootstrap method were comparable to the classical techniques, indicating that bootstrap can be an alternative approach in a specific context of trade volume. We also illustrated on what extent the bias corrected and accelerated non-parametric bootstrap method produces different estimate of interest, as compared by non-parametric bootstrap method.

Community residents are tend to evade waste treatment facilities such as waste landfills, waste incinerators. Therefore, decision-makers of waste management are concerned about the reduction and recycling of food garbage. As a treatment alternative of food garbage which consists of 30% of municipal waste, producing compost and feed stuff from food garbage is environmentally amenable. In considering the characteristics of food garbage are putrid and high moisturized, methods of landfilling and incineration for food garbage are environmentally inadequate. For the institutionalization of food garbage recycling, separate discharge, establishment of collection system, securing of market for compost and feed stuff manufactured from food garbage, and tax and financial incentives for food garbage recycling facilities are necessary.

Titanium(Ti) alloys has been mostly concerned with biocompatibility, corrosion resistance, and biofunctionality. However, very little is known, about the biological effects of titanium on microorganism and in particular on the oral flora. So, the effect of titanium on the in vitro growth of oral microorganism forming dental caries was studied under either aerobic or anaerobic condition. In this study, the mostly bacterial species commonly found in dental plaque or gingival sulcus grew well in an aqueous medium containing $100{\mu}g/ml$ of titanium standard solution.

Hantavirus are rodent-borne RNA virus that belongs to the family Bunyaviridae. Those viruses persistently infect a variety of rodents, and are transmitted by aerosols of their urine, feces and saliva. Antibody titers of sera obtained from normal laboratory rodents against hantaviruses were investigated by indirect immunofluorscence antibody technique (IFA), Seroconversion rates of normal laboratory rodents showed higher in rats than that from hamster and mongolian (M). gerbil. Theses rates of normal laboratory rodents also showed higher in titers against puumala virus (PUUV) than in hantaan (HTNV) and seoul virus (SEOV). We are concerned about infections caused by hantaviruses, especially by PUUV, occurred in laboratory rodents.

This paper aims at investigating the realities of puerperal period of Korean women, chiefly in the city of Seoul, on the basis of their living standard, schooling caree by age groups, to contribute to the improvement in health of mother and child. In this paper in which the writer, aming 492 women in Seoul a subject of this investigation and giving them 34 items of questionnaires, has studied their concern and practices to recover their health during a lying-in period, and drawn a conclusion as follows : Though their place of childbirth and food they take during the period are varied according to their standard of living, their practices and managements after parturition are true to the conventional usage which is far from modern scientific methods. Problems for the better management during puerperal period are : 1. to have expactent and nursing mothers better educated in their antenatal care ; 2. to let the family planners have more understanding about the problems of puerperal period ; 3. to make those who are concerned study on the problems interdependent between puerperal period and pregnancy and child birth.
