PURPOSE. The aim of the study was to evaluate the effect of annealing on the nanostructure and hardness of Co-Cr metal ceramic samples that were fabricated with a direct metal laser sintering (DMLS) technique. MATERIALS AND METHODS. Five groups of Co-Cr dental alloy samples were manufactured in a rectangular form measuring $4{\times}2{\times}2$ mm. Samples fabricated by a conventional casting technique (Group I) and prefabricated milling blanks (Group II) were examined as conventional technique groups. The DMLS samples were randomly divided into three groups as not annealed (Group III), annealed in argon atmosphere (Group IV), or annealed in oxygen atmosphere (Group V). The nanostructure was examined with the small-angle X-ray scattering method. The Rockwell hardness test was used to measure the hardness changes in each group, and the means and standard deviations were statistically analyzed by one-way ANOVA for comparison of continuous variables and Tukey's HSD test was used for post hoc analysis. P values of <.05 were accepted as statistically significant. RESULTS. The general nanostructures of the samples were composed of small spherical entities stacked atop one another in dendritic form. All groups also displayed different hardness values depending on the manufacturing technique. The annealing procedure and environment directly affected both the nanostructure and hardness of the Co-Cr alloy. Group III exhibited a non-homogeneous structure and increased hardness ($48.16{\pm}3.02$ HRC) because the annealing process was incomplete and the inner stress was not relieved. Annealing in argon atmosphere of Group IV not only relieved the inner stresses but also decreased the hardness ($27.40{\pm}3.98$ HRC). The results of fitting function presented that Group IV was the most homogeneous product as the minimum bilayer thickness was measured (7.11 ${\AA}$). CONCLUSION. After the manufacturing with DMLS technique, annealing in argon atmosphere is an essential process for Co-Cr metal ceramic substructures. The dentists should be familiar with the materials that are used in clinic for prosthodontics treatments.

Purpose: This exploratory study was undertaken to analyze the information needs of family members of terminal cancer patients, collected through the telephone counselling service by National Cancer Information Center. Methods: The study included 113 family members of terminal cancer patients who had enrolled at the National Cancer Information Center for the period from June, 2007 through March, 2008 and had agreed to the survey. Results: The subjects (n=113) consisted of grown-up children (n=82) and spouses (n=8) of patients'. Those in their 40's (n=40) and 30's (n=36) accounted for the majority of the sample. The questions raised most were about the information on treatment methods (n=117), management of terminal cancer patients (n=46), terminal cancer patients' life (n=27), deathbed and prediction of remaining life (n=18), hospitalization (n=16), and financial support (n=15). Most of the subjects were satisfied with the telephone counseling services, and 69% of the subjects had come to know about the telephone counseling service via Internet, and 10.6% of them stated that the PR for the service was poor. Conclusion: It is deemed essential for the government to use the mass media for PR of the hospice services, since family members of terminal cancer patients' are less aware of the hospice conducive to enhancement of patients' remaining quality of life, being involued too deeply in their treatment.

Approaching to aging society with increasing transportation vulnerable, most developed countries has positively promote low-floor bus. Such circumstance in Korea has plan to introduce low-floor bus to intra-city bus system which accounted for 30 percent of total number of buses however there is no specific operating plan for this matter. According to the revealed preference study on bus service, the study shows that the efficiency of low-floor is relatively low than that of other buses, therefore, it is necessary to establish feasible plan for bus route selection. Thus, this study is to conduct research on analyzing trip characteristics of transportation vulnerable and establish bus route selection measures for low-floor bus. The result from the survey in Jeollabuk-do Province reveals that the trip purpose of transportation vulnerable is mainly for welfare and medical service, which was made less than 6 times a week. Futhermore, 37.6 percent of transportation vulnerable use buses, thus, it is essential to improve its service quality for enhancing user's convenience and safety. In that transportation vulnerable O-D needs to be established and forecasts future demand for selecting optimal bus route. According to the estimation, route passing through densely populated areas with transportation vulnerable should take the first priority, city circular and other route would be next. Moreover, it is economically efficient that areas populated more than 200,000 with fixed route and less than 200,000 with limited route responsive to demands would be feasible plans. This study will have greater an impact on transportation planning and further research on transportation vulnerable.

As cities become overcrowded and concentrated, the demand for public services continues to increase due to the improvement of the living standards of urban residents. Among them, fire service can be seen as one of the important public services by reducing damage caused by accidents in emergency situations and affecting the improvement of access to medical services for urban residents. Rapid movement of patients and medical institutions within golden time and proper first aid are essential elements in emergency situations, and Seoul is a super-large city with a large population of about 10 million people and has a large number of emergency medical patients. Therefore, this study used spatial regression analysis to examine the factors affecting the delay factors of emergency dispatch in Seoul to secure golden time, and derived management priorities, and suggested implications for the management of emergency vehicle dispatch delay factors. As a result of the main analysis, land-use characteristics were the most influential factor in emergency vehicle dispatch time, and land-use mixing, commercial area density, average patient age, and average road length were found to affect emergency vehicle dispatch time in order. This study can be used as important basic data for an accurate understanding of the delay factors for emergency dispatch and preparing countermeasures according to priorities.

Along with the development of scientific technologies, health care has been growing remarkably, and as the social life quality improves with increasing interest in health, the demand for medical service is rapidly increasing. However, medical accident and medical dispute also are rapidly increasing due to various factors such as, increasing sense of people's right, lack of understanding in the nature of medical practice, over expectation on medical technique, commercialize medical supply system, moral degeneracy and unawareness of medical jurisprudence by doctors, widespread trend of mutual distrust, and lack of systematized device for solution of medical dispute. This study analysed 30 cases of civil suit in the year between 1994 to 2004, which were selected among the medical dispute cases in dental field with the judgement collected from organizations related to dentistry and department of oral medicine, Yonsei university dental hospital. The following results were drawn from the analyses: 1. The distribution of year showed rapid increase of medical dispute after the year 2000. 2. In the types of medical dispute, suit associated with tooth extraction took 36.7% of all. 3. As for the cause of medical dispute, uncomfortable feeling and dissatisfaction with the treatment showed 36.7%, death and permanent damage showed 16.7% each. 4. Winning the suit, compulsory mediation and recommendation for settlement took 60.0% of judgement result for the plaintiff. 5. For the type of medical organization in relation to medical dispute, 60.0% was found to be the private dental clinics, and 30.0% was university dental hospitals. 6. For the level of trial, dispute that progressed above 2 or 3 trials was of 30.0%. 7. For the amount of claim for damage, the claim amounting between 50 million to 100 million won was of 36.7%, and that of more than 100 million won was 13.3%, and in case of the judgement amount, the amount ranging from 10 million to 30 million won was of 40.0%, and that of more than 100 million won was of 6.7%. 8. For the number of dentist involved in the suit, 26.7% was of 2 or more dentists. 9. For the amount of time spent until the judgement, 46.7% took 11 to 20 months, and 36.7% took 21 to 30 months. 10. For medical malpractice, 46.7% was judged to be guilty, and 70% of the cases had undergone medical judgement or verification of the case by specialists during the process of the suit. 11. In the lost cases of doctors(18 cases), 72.2% was due to violence of carefulness in practice and 16.7% was due to missing of explanation to patient. Medical disputes occurring in the field of dentistry are usually of relatively less risky cases. Hence, the importance of explanation to patient is emphasized, and since the levels of patient satisfaction are subjective, improvement of the relationship between the patient and the dentist and recovery of autonomy within the group dentist are essential in addition to the reduction of technical malpractice. Moreover, management measure against the medical dispute should be set up through complement of the current doctors and hospitals medical malpractice insurance which is being conducted irrationally, and establishment of system in which education as well as consultation for medical disputes lead by the group of dental clinicians and academic scholars are accessible.

In this county, the gap between the urban 'haves' and the rural 'have-nots' continues to be an increasing problem. WHO and UNICEF see primary health care(PHC) as the key to achieving an acceptable level of health throughout the world as a community development. PHC is essential health care made accessible to individuals and families in the community by means acceptable to them. It is the first level of contact of individual, the family, and community with the national health system. It includes at least education on health system. It includes at least education on health problems, promotion of food supply, MCH including family planning, immunization against infectious diseases, control of endemic diseases, treatment of common diseases and injuries, promotion of mental health, and provision of essential drugs. However, of the aboves, education concerning of mental health problems and the methods to identify, prevent, and control them is the principal step of establishment. In Korea, the category of PHC worker includes the physician as public doctor and nurse as primary health care practitioner and community health leader as village health worker. PHC workers of the aboves will thus function best if they are appropriately trained to respond to the health needs of the community. However in this country, since the national PHC service project launched in 1980, the government has not developed and performed appropriate and enough education and training activities. In light of above reasons, several categories of health education activities had been planned and performed being aimed at above specific target groups and the main focus was on the village health workers for about one year from July 1991 to July 1992 in Yeoju Kun of Kyonki Province. At the end of the period, evaluation of education input was carried out to measure the improvement of healthful life of people in terms of awareness, attitude, and practice. At the end of the period, evaluation of education input was carried out to measure the improvement of healthful life of people in terms of awareness, attitude, and practice. The totals of 80 village health workers, 13 public health practitioners and 9 public docters took in the course of health education for a few hours at every month and the evaluation works of educational effect were taken. The results the study were as follows. 1) Number of persons who realized the maxim "health care of the people is a duty of the government" increased after the education course, On the other hand, the rate of satisfaction on the effort of government for health promotion of the people decreased. 2) Public doctors and primary health care practitioners(nurses) liked and enjoyed the education schedule as a meeting of peer group. It provided chances of communication with staffs of Korea University Hospital. It was said that lectures covered great deal of knowledge and technic they urgently needed in the field. 3) After finishing the education course, more of village health workers(VHW) thought they adapted themselves to their roles and functions showing increased number of home visit and contact with primary health care practitioners by month. 4) In case of patient refer, VHW preferred primary health care practitioners to public doctors. 5) Capability of VHWs in most of their functions increased dramatically after when the education course finished except tuberculosis control.

Background: Inadequate samples make laboratory tests delay cause errors, which will deteriorate the quality of the tests. Therefore, adequate samples are essential for reliable test result. To reduce the inadequate samples, they should to analyze problems and seek a way of improvement through CQI (Continuous Quality Improvement) activity. This will minimize errors during the test and produce a fast and accurate result. Eventrally, the qualily of entire test may be improved, and as a result, a good quality of medical care service may be provided. Methods: At first, inappropriate testing items were collected. Then, generating fctors and problems were investigated and analyzed in each case, In addition, the category with higher frequency wes primarily supervised. In consegalnce, a reduction of are dustion of improper testing sample was oxpected through continuous education and CQI activity. Conclusion : At the beginning of CQI activitv, the number of inadequate testing sample was of 8,591 total samples, which gives the frequency of 0.72%. As CQI activity was carried out the number of improper testing sample reduced to 58 out of 11,415 cases, which yields the frequency of 0,51%. One may notice the difference 0.2%. Among the inadequate sample(blood), there was a high frequency of hemolysis; thus, more of CQI activity is required for this specific matter. Because the occurrence of inadequate testing affects the clinical outcomes, it is extremely important that one manages each step of the procedure in collecting samples and mamtaines the quality of entire tests.

The purpose of this study was to identify the relationship between organizational culture based on the competing values approach, human resource management practices and organizational performance at a hospital. Participants were 138 employee in a general hospital. Data were collected during May, 2003 using four structured instruments. The data were analyzed using Chi-square test, One-way ANOVA, $scheff{\acute{e}}$ test and Cluster analysis. Three clusters were derived from cluster analysis. The first cluster consisted of cultures which were mixed developmental, consensual, hierarchial and rational culture equivalently. The second cluster consisted of the weak cultures, which was lower score than other clusters. The third cluster consisted of strong comprehensive cultures, which had higher score than other clusters. In the three clusters, hierarchial and rational culture were superior. The difference between human resource management practices and organizational commitment in organizational performance according to organizational culture clusters was found to be statistically significant. The cluster which had strong comprehensive cultures, in contrast to other clusters, more significantly affects on human resource management practices and organizational commitment. However, the strength of organizational culture does not have a significant effect on customer oriented service performance in organizational performance. These results showed that types of organizational culture were significantly related to human resource management practices and organizational commitment, and understanding the existing culture is essential to develop the organization of hospitals.

Since the national health insurance was introduced in 1978, the increased utilization of hospitals and the growing importance of pharmaceutical services to hospital patients have made the administration of these services a very complex and specialized responsibility. The pharmaceutical services has always been an essential component of comtemporary hospital care. In the hospital, the pharmaceutical services is the professional department which concerns itself with the evaluation, selection, control and utilization of drugs. The director of this service must be a versatile professional person who can work effectively in a heterogenous society of educated persons. However, graduate education in hospital pharmacy has not been introduced yet in Korea. The necessity of graduate education hospital pharmacy has been discussed in this research. Graduate education in hospital pharmacy emphasizes preparation for assumption of responsibility as the senior hospital pharmacist or the director of pharmaceutical services. Graduates should also be prepared as administrators of a department that must operate with great efficiency. They should be prepared serve as a consultant on drugs for the medical and allied health professional staff, organizing and disseminating a large and dynamic body of information in their interest and to establish professional roles that emphasize procurement, storage, manufacturing, packaging, distribution, control and evaluation of drugs. Senior hospital pharmacist is a teacher charged with responsibility fer formal and informal instruction of other hospital personnel in pharmaceutical sciences. In addition, the graduates have the opportunity to be a researcher dealing with aspect of hospital care and are intensively educated in the professional aspects of hospital pharmacy practices. The curriculum of graduate education in hospital pharmacy should be established detailly and carefully to fit the educational objective.
