Monochromatic x-ray CT has several advantages over conventional CT, which utilizes bremsstrahlung white x-rays from an x-ray tube. There are several methods to produce such monochromatic x-rays. The most popular one is crystal diffraction monochromatization, which has been commonly used because of the fact that the energy spread is very narrow and the energy can be changed continuously. The alternative method is the use of fluorescent x-ray, which has several advantages such as large beam size and fast energy change. We have developed a parallel-beam and a fan-beam monochromatic x-ray CT, and compared some characteristics such as accuracy of CT numbers between those systems. The fan beam monochromatic x-rays were generated by irradiating target materials by incident white x-rays from a bending magnet beam line NE5 in 6.5 GeV Accumulation Ring at Tukuba. The parallel beam monochromatic x-rays were generated by using a silicon double crystal monochromator at the bending magnet beam line BL-20BM in Spring-8. A Cadmium telluride (CdTe) 256 channel array detector with 512mm sensitive width capable of operating at room temperature was used in the photon counting mode. A cylindrical phantom containing eight concentrations of gadolinium was used for the fan beam monochromatic x-ray CT system, while a phantom containing acetone, ethanol, acrylic and water was used for the parallel monochromatic x-ray CT system. The linear attenuation coefficients obtained from CT numbers of those monochromatic x-ray CT images were compared with theoretical values. They showed a good agreement within 3%. It was found that the quantitative measurement can be possible by using the fan beam monochromatic x-ray CT system as well as a parallel beam monochromatic X-ray CT system.

The hospice activities in Korea have still stood in the premature stage, although the contemporary hospice program, which professionally accommodates terminally ill patients, appeared in the history 35 years ago. Especially, the availability of the facility hospice is not only poor in number, but also lack of a guideline for the conduct of the facility. Saemmul Hospice has keenly felt the necessity of more facility hospices and has interchanged experiences and informations with people interested in hospice. However, the number of facilities has fallen short of one's expectations, and many problems have been revealed in order to maintain the operation. This paper was written in order to improve these atmospheres and to help more terminally ill cancer patients properly. This paper clarifies in detail the principle of management, the method of practice in each departments of Saemmul Hospice, expected effects and supplemental items. We try to provide concrete and practical informations and to help extensively for all peoples who are to begin or currently working. 1.Facility: It secures, maintain, and manage the hospice environment for all around care of patients effectively. 2.Education and Volunteer: It trains and manages hospice volunteers devoted to hospice. 3.Financial: It manages donation by healthy soul with an effective method. 4.Administration and Organization: It executes the administration efficiently and constitutes the organization to operate. 5.Medical and Nursing: It offers the maximum professional supports to a hospital. 6.Medicine and alternative medicine: It improves the quality of life of patients by medical and pharmaceutical approach and by other possible methods available. 7.Nutrition: It helps patients to have diets in accord with the order of the creation. 8.Belief: It offers spiritual care which allows the profound relationship with God. 9. Funeral ceremonies: Funeral ceremonies may heal grieves of families faced with their deaths. 10. Bereaved families: It supports the families after the deaths of patients. 11.Reception and consultation: It seeks to help the patients who meet the purposes for which Saemmul Hospice is established. 12.Publication: It allows publicity activities for Saemmul Hospice. Facility hospice programs are able to overcome the disadvantages that the other type of the hospice possess, like as the economic burdens of the families, and the patients' losses of comforts of home after being transferred to a hospital. Facility hospice can provide home atmosphere with professional manpower and facilities like hospital to the patients. Therefore, it can also improve patients' qualities of life and make them comfortable death. We anticipate that the hospice program in Korea would be more active to let more people be indebted to maintain the nobel human dignity and to cross beautifully in the most painful process of dying in the journey of their lives.

Genetic polymorphisms of uridine diphosphate-glucuronosyltransferases 1A6 (UGT1A6) and 1A7 (UGT1A7) may lead to genetic instability and colorectal cancer carcinogenesis. Our objective was to measure the interaction between polymorphisms of these repair genes and tobacco smoking in colorectal cancer (CRC). A total of 68 individuals with CRC and 112 non-cancer controls were divided into non-smoker and smoker groups according to pack-years of smoking. Genetic polymorphisms of UGT1A6 and UGT1A7 were examined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). We found a weak association of UGT1A6 polymorphisms with CRC risk (crude odds ratio [OR], 1.65;95% confidence interval [95% CI], 0.9-3.1, P=0.107; adjusted OR 1.95%, 95% CI 1.0-3.8, P=0.051). The ORs for the UGT1A7 polymorphisms were statistically significant (crude OR: 26.40, 95% CI: 3.5-198.4, P=0.001; adjusted OR: 21.52, 95% CI: 2.8-164.1, P=0.003). The joint effect of tobacco exposure and UGTIA6 polymorphisms was significantly associated with colorectal cancer risk in non-smokers (crude OR, 2.11; 95% CI, 0.9-5.0, P=0.092; adjusted OR 2.63, 95% CI, 1.0-6.7, P=0.042). In conclusion, our findings suggest that UGT1A6 and UGT1A7 gene polymorphisms are associated with CRC risk in the Japanese population. In particualr, UGT1A6 polymorphisms may strongly increase CRC risk through the formation of carcinogens not associated with smoking.

A general concept of Geun includes the soft organizations such as a muscle, a myofascia, a tendon and a ligament, cartilages and nerves that surround it. The main function of it is a movement of the body such as a flextion and a extension, a connection of the joints, and a construction of the body shape. Lately, we consider Geun important little by little, develop a variety of the therapeutic measures which make use of it, and apply it to the treatment in the oriental medicine, And the therapeutic measures which utilize Geun will be developed from now on. Therefore, this study reviewed and analyzed the direction of the research referred to Geun in the oriental medicine and the tendency to the experiment to grow the study referred to Geun in oriental medicine continuously and developed the new direction. This study collected 44's theses reported in the oriental medical journal and analyzed in accordance with the journal, time, form and topics. The following results were obtained in this study; 1. In the theses referred to Geun, the journal of Korean acupuncture & moxibustion society and of Korean oriental medicine have the most of them(11's theses) and at the next the journal of oriental rehabilitation medicine has 9's theses. 2. By analyzing the form of the theses, these were classified into the theoretical, experimental and clinical studies. The theoretical these occupied 39%, the experimental theses 54%, and the clinical theses 7%. 3. By analyzing the theses referred to Geun, these were classified into the muscular abnormality - such as a powerlessness, a injury, a atrophy, a disorder, and a pain - the theory of muscles along the regular meridians, the muscular organization, the therapeutic measures, the manipulation and so on. 4. The theses of the muscular abnormality occupied 30% of them referred to Geun and the theory of muscles along the regular meridians 20%, the muscular organization 12%, the therapeutic measures 12%, and the manipulation 8%. According to the above results, the study of the new field referred to Geun and the clinical report are indispensable since the field is limited and the tendency is theoretical and experimental.

This study identified the relationships between the hospital’s organizational pattern for nursing, the organizational characteristics perceived by nurses and their job satisfaction. The study subjects were a convenience sample of 383 staff nurses working at 10 general hospitals with more than 300 beds in Seoul. Hospitals included in the study were classified Into five organizational patterns, where nursing was organized as an independent but lower level, attached to the medical department, attached to a department supporting medicine, and various other organizational pattern. The data were collected from July 10 to August 15, 1992. The organizational characteristics as perceived by the staff nurses were measured by Park & Yoon’s Scale (1986) and job satisfaction was measured by Slavitt’s Scale (1978). The data were analyzed by percentage distribution, Pearson’s correlation, x$^2$-test, t-test, ANOVA, and ANCOVA The summarized results are as follows : 1. The proportion of independent and attached nursing organizational patterns was 35.1％ and 54.9％ respectively. 2. There were differences between four general characteristics of the nurses, age, experience, position and education level, and the five structural types of nursing organization(p〈.05). 3. 1) There were no relationship between the perceived organizational characteristics and general characteristics of the nurses but there was a differ once in job satisfaction according to education level of nurses in hopitals where nursing was an independent department(T=-2.24, p〈.05). 2) There were differences in the perceived organizational characteristics according to age group and experience of nurses (F=3.26, 5.41, p〈 , 05)and in job satisfaction according to the position of nurses in the independent but lower level organizational pattern (T=2.26, p〈.05). 3) There was a difference in the perceived organizational characteristics according to age group (F=3.19, p〈 .05) and in job satisfaction according to the experience of nurses where nursing was attached to the medical department (F=3.49, p〈.05). 4) There was a difference in the perceived organizational characteristics according to nursing unit (F=3.19, p〈 .05), but none between job satis-faction and general characteristics of nurses where nursing was attached to a departiment supporting medicine. 5) There were no relationships between the perceived organizational characteristics and job sat isfaction and general characteristics of nurses in the various other organizational patterns. 4. Nurses in hospitals where nursing is organizationed as an independent department perceived their organizatianal pattern more positively and had higher job satisfaction than nurses working in hospitals where nursing is part of another department. 5. There were differences between perceived organizational characteristics and job satisfaction according to the organizational patterns for nursing (F=13.52, 8.76, p=.0000). 6. There were correlations between the perceived organizational characteristics and job satisfaction of nurses working in two independent nursing departments (r=0.2180, 2351, p〈.05). In conclusion, the relationship between perceived organizational characteristics and job satisfaction was significantly correlated in the hospitals where the nursing department is independent. Perceived organizational characteristics and job satisfaction depended on whether the nursing department is independent from or attached to other departments in the hospital. For nurses job satisfaction the nursing department should be independent from other departments and at the highest level of organization in the hospital.

The purpose of this study is to promote the efficiency of the management of the controls organization in the university hospitals and general hospitals by evaluating the factors underlying organizational conflict. The subject population included 351 hospital workers randomly selected from two general hospitals of less than 200 beds and two university hospitals over 500 beds in Seoul area. Data were collected through a survey questionnaire. To define related factors for the level of conflict among departments in each hospitals multivariate regression analysis was conducted. Independent factors were characteristics of subjects, conflicting factors between the departments. The results are as follows: 1. Those in high job position group demonstrated significantly higher level of conflict between departments. Those working in the general hospitals, who were older and had long-term tenure at current working hospital had higher level of conflict between the departments. 2. Concerning the involvement of conflicting factors and the level of conflict in the employees' there was statistically significant positive correlation between reliability and job-related and intradepartmental level of conflict in university hospitals. There was a significant positive correlation between interdepartmental conflicting factors of mutual dependence, difference in goal/orientation and interdepartmental level of conflict. 3. In the university hospitals, among the interdepartmental factors, mutual dependence and difference in goal/orientation had statistically significant influence and showed a positive relationship with interdepartmental level of conflict. In the general hospitals, job position was a significant factor which showed that those in high position such as section chief or above, compared to those in general position had higher level of conflict. Among the interdepartmental characteristics, factors of mutual dependence and goal/orientation had statistically significant influence and showed a positive relationship with interdepartmental level of conflict. In the general hospitals setting efforts to reduce conflict in areas among workers with high position, old age, and long tenure and those in medical care department should be made and prudent management and planning for improved manpower and increased budget or efficient allocation and clear definition of job description are necessary to adequately assess. In the university hospitals setting efforts to reexaminitation of the organizational structure and efficiency conveyance of information and efforts to resolve conflict among young workers with lower level of education is need. This study has its own merit in comparing empirically the conflict among hospital workers in the university hospitals and general hospitals. Future study are needed with respect to the relationship between interdepartmental level of conflict and the effectiveness of the hospital organization for improved resolution of conflict in the organization and hospital management.

As becoming an aging society, there is a rising interest on dementia. But Dementia prevention program, executed at the national level, is in insufficient state. In this study, to design and diffuse Dementia prevention program, this study conduct Cognition improvement program and evaluate cognitive function in aspects of Discrimination, Organization, Thinking, Memorizing, and Concentration capacity. So that this study try to investigate how this Cognition improvement program will affect in detail to cognitive function in senior people. This study designed Silver Cognition program for 5 aspects of cognitive function; Discrimination, Organization, Thinking, and Concentration capacity. And this studyrecruited experimental group with control group, and conducted the program to them for 3 months. At the start and the end of the program, this study evaluated their MMSE-DS score, Geriatric depression scale, Quality of life score, and cognitive function test score by survey. Finally, this study compared and analyzed these first and second score to find the effects of this program to cognitive function. As the results compared between first and second score of MMSE-DS test, Geriatric depression scale, Quality of life scale, and cognitive function test, Silver Cognition program has a significant effects to improve cognitive function, MMSE-DS score and Geriatric depression scale. As the results of the test on cognitive function in 5 aspects, cognitive function is more improved in the order of Memorizing, Thinking, Concentration, Discrimination, and Organization capacity. After the Silver Cognition program, Memorizing and Thinking capacity have most improvement. But aging of brain function is faster in these two capacity, so if more concentrated education is conducted for these two capacity, then it will bring better effects for prevention of dementia.

This research is an attempt to establish a basic material in discovering the subjective types of the dental coordinators occupational consciousness, utilizing the Q-Method Theory, which is capable of measuring the subjective nature of human being by scientific and systematic method. The characteristics of each type were analyzed so as to have the dental coordinator to possess the desirable understanding of the occupational view together for them to have self-confidence as a lifetime specialty occupation. Upon completion of the study, it was found that there are three types of subjective views pertaining to the occupational consciousness on the dental coordinator. The result on the analysis of the characteristics is as follows : Type 1 is the Taking Serious View on the Patient Service, which priority is placed on kindness and looking after any difficulties of the patient, namely, it is the type that puts the importance on the high level medical examination and treatment based on good service. Because of the kind service to the patient, those under this category considered their job satisfaction have been improved. It goes without saying that they were developing the services, which satisfy themselves, and it was confirmed that they thought that they should make things smooth for any development of problems that may arise between the patient and the dentist. Type 2 is the Taking Serious View on Career and Organizational Strength. This is a type that aims on the systematic nature of the internal job, namely, organizational strength itself viewed from the stand point thai either self-confident or work merit is proportional to experience. This type is to actively treat the problem and endeavor to solve the issue when dissatisfaction is held by the dental hospital system, which is either followed according to the work responsibility or by an organization having an appropriate system on remuneration, Type 3 is the Placing of Importance on the Overall Circumstances. This is the type that places importance on the overall now of the dental hospital, and it is the type, that most greatly recognizes the importance of the role of the dental coordinator. The dental coordinator should provide the sense of reliability to both the dentist and to the staff of the medical examination and treatment and should be able to adjust smoothly the overall now of the medical treatment. The dental coordinator is expected to be a medical service specialist, who is capable to solve the problems of the staff of the medical treatment intuitively and to adjust the relation between the employees. With the above result, it was found that although there was no mutual exclusiveness between the respective types, there are particular characteristics among each type. Therefore, this research has discovered and analyzed the subjective view types relative to the occupational consciousness of the dental coordinator for the proper understanding on the characteristics of each type to enable the dental sanitary students and the graduates of the Dental Sanitary Department, who are aspiring to become dental coordinator, as the basic guide material to be actively utilized.
