Statement of problem. Glass fiber post is one of recent developments to accommodate esthetic restoration for endodontically treated teeth. This has many advantages over conventional post system in physical properties, esthetic factor, risk of root and restoration fracture, adhesion to core, radiopacity, removal and retrievabilty, biocompatibility and chemical stability. Purpose. This in vitro study was to evaluate the most suitable type of resin core for the glass fiber post through surveying the fracture modes and the maximum load that fractures the tooth. Material and methods. 50 sound maxillary premolars restored with glass fiber posts($ParaPost^{(R)}$ Fiber White) and different types of resin cores(ParaCore, $Z100^{TM}$, $Rebilda^{(R)}$ and $Admira^{(R)}$) were prepared and loaded to faiure in a universal test machine. The maximum fracture load and fracture mode were investigated in the specimens that were restored with resin and those of metal cast and core. With the data, Wilcoxon rank sum test was used to validate the significance between the test groups, and Tukey' s studentized range test was used to check if there is any significant statistical difference between each test group. Every analysis was approved with 95% reliance. Results. On measuring the maximum fracture load of teeth specimens, there was a significant difference between the maximum fracture loads of the tooth specimens. ParaCore showed the highest mean maximum fracture load followed by $Z100^{TM}$. And, the distribution of fracture mode of tooth specimens showed generally Type D, the three parted fracture of the core around the post was mostly seen(62.5%), and specifically, ParaCore showed 90% and $Z100^{TM}$ showed 100% Type D fracture. Conclusion. Referring to the values of maximum fracture load and mean compressive fracture load, ParaCore and $Z100^{TM}$ had high values and are recommended as tooth colored resin core material for glass fiber post. CLINICAL IMPLICATIONS. This study was carried out intending to be of aid in selecting the appropriate resin core for the glass fiber post. The dual cure type composite resin ParaCore and light cure type composite resin $Z100^{TM}$ have good properties and are recommended as tooth colored resin core material for glass fiber post.

This research examines the characteristic of regulation on Japanese clinical research in recent years. First, Japan has had a severe punishment policy on research misconduct like Korea, but, in recent days, Japan has changed the direction of research ethics policy from restriction to research publicness securement by educational training, in addition, Act of Clinical Research, effected April 2018, has recruited excellent researchers, and then integrated clinical research and medicine clinical trial through raising transparency of funding and integrating ethics screening by mandating announcement on funding information of clinical research. Second, Japan has integrated and organized ethics guideline from dual system that consists of ethics guideline on dynamic research(here after, referred to as 「dynamic guideline」) and ethics guideline on clinical research(here after, referred to as 「clinical guideline」) to ethics guideline on medical research aimed at human(here after, referred to as 「integrated guideline」), thus, it complements repetition and deficit of ethics guideline needed in clinical research and dynamic research, and it has risk evaluation system for protecting human subjects, and also it clarifies the concept of 「invasiveness」, a preliminary consideration of evaluation. 「Evaluation issue of risk and profit」, common contents of international regulation related clinical research, is the method to check whether the research is designed appropriately or not, this is the method for Institutional Review Board to decide whether the risk on human subjects could be justified, and also this is the important standard for future human subjects to participate in clinical trial. Therefore, it is meaningful to define 「invasiveness」 concept, a preliminary consideration of risk evaluation for human subjects. This research examines Japanese clinical trial focusing on change of awareness on prevention of research misconduct, efficiency improvement of research through research screening and integration of human subjects, and clarification and extension of range of 「invasiveness」 concept, a preliminary of risk evaluation to protect human subjects.

As the concern about health is increased, the importance of preventive medicine that prevent disease in advance to overcome boundary of disease remedy gets emphasized in the whole world. The fundamental thoughts of oriental medicine are the harmony between the human body and nature, the unified idea regarding mind in the same light with body, and the symmetry of the cosmo dual forces. And oriental medicine is a kind of study that has developed on the ground of prevention thought. from old days, it has been developed the preventive medicine at is called 'Yangseng(養生; recuperation)' etc. with the clinical medicine. The preventive medicine of oriental medicine was taking a serious of the first preventive medicine of an incurable disease thought and the prevention thought that belongs to the second and third preventive medicine is described through the whole oriental medicine. Also the clinical and preventive medicine to apply to the clinics have an in- separable relation. Therefore I inspected the part of the preventive medicine described in some oriental medicine books and studied the characteristics of preventive medicine of oriental medicine as follows; First, the preventive medicine of oriental medicine has the characteristics that is emphasized generally in the first preventive medicine and wholly it is composed in the system of the first, second and third preventive medicine. It has the presentative theory such as 'Jungkijonae sabulkaghan(正氣存內 邪不可干; If good energy is in body, a disease. dosen't occur)', 'Husajukpung Phijeyushi(虛邪賊風 避之有時; When e infectious disease like plague break out, they must avoid the place occurring the disease)', 'Chuninsangeung(天人相應; The harmony of nature and human)' etc.. This is intimately related to the incurable disease thought of the inside diameter and oriental medicine has pursued that. Second, due to the most prerequisite theory of disease production, the balanced condition of environment, the cause of a disease and host is called the health. As oriental medicine has the system of aetiology like that, we can see the host and environments are importance most of all. Namely we can think of the relation of host >> environment > the cause a disease Up to date Jungkijonae Sabulkaghan(正氣存內 邪不可干) that the most oriental medicine doctors have had a knowledge is not whole theory but a pan of oriental medicine science and it is included in oriental medicine theory to avoid infectious disease such as Husajukpung Phijeyushi(虛邪賊風 避之有時). Third, according to the natural result of the first and second contents, we can know that its characteristics stress the remedy without drugs. Because Jungkijonae Sabulkaghan(正氣存內 邪不可干), Husasukpung Phijeyushi(虛邪賊風 避之有時), and Chuninsangeung(天人相應) mean that they prevent disease in condition of freedom from ailment, We can prevent the disease production through the positive preventive methods such as exercise, spirit, food and innate prevention etc.. fourth, the preventive medicine of oriental medicine has developed with therapeutics and it contains all oriental medical methods such as host, environment, exercise, acupuncture and moxibustion, innate or postnatal methods. Also it is the general preventive medicine that has fundamental philosophy of oriental medicine; for examples, the unified idea, the harmony of nature and human, and the unity of mind and body. fifth, to develope the above scientific merit and special features, the preventive medicine of Oriental medicine must be objectified and reemergent stud? gets more and more essential from now on. Especially we need to have the scientific concern of Oriental medicine about the cause of a disease, environmental hygiene, industrial sanitation, and personal hygiene etc..

Occupational health services in Korea have been operated as dual types : one is operated by occupational health care manager and the other is health care agency without their own personnel. The performance of occupational health service should be different due to the variety of characteristics of health care manager and workplace, qualification of health care manager. This study is to analyze performance of occupational health care services with a particular consideration of job performance shape and efficiency, based on comparing those two types of health care management to show on the basic data for the settlement of more qualitative health care management system at workplace. For this study, total 391 places in Seoul and Inchon city area ; 154 places (39.4%) managed by designated health care manager and 237 places (60.6%) by the agency with their commission are selected as research samples. Tools for data collection are questionnares that have been investigated during the period of 20 September 1993-20 December 1993. Those data are compared with percentiles, mean, standard deviation and B/C ratio using SPSS PC program. Conclusions observed from the tests and each comparison could be summerized as follows : 1. Occupational health care have been accomplished at workplaces with designated people than with agencies people, and coverage rate of the occupational health care services has differences, due to management types. The reason of these results is due to visit only one or two times monthly by the agencies, while their own health care manager obsess, at the workplaces all the times. 2. Most of the expense for environmental control of all health care services expenditures shows that there is almost no fundamental improvement because more expenses are needed for procuring personal protective equipment and measuring work environment instead of environmental improvement. 3. It is investigated how much the cost of occupational health care services needs per worker, and calculated how much the cost needs per service hour per worker. The results from this show that the cost of occupational health services at workplaces with their own managers used less than the cost of health care agencies, eventually the former gives better services with less cost than the latter. 4. Benefit/Cost ratio is also produced by total benefit/total cost. The result from the above way reads 4.57 as a whole, while their own manager having workplaces reads 4.82 and the agencies do l.56. Even if their own manager performing workplaces spent more cost, this system produces more benefit than the agencies management. 5. The B/C ratio for medical organization such as local clinic, health care center and pharmacy shows more than or equal to at the workplaces controlled by the agencies. It is inferred that benefit would be much less than the cost used, with so being inefficient. 6. It is assumed that the efficiency ratio of health education is equal to reduction rate of workers medical organization visit. Estimated reduction rate 5%, 10%, 15%, show that the efficiency ratio of health education have an effect on producing benefits. It is estimated that more benefit can be produced if more qualitative education will be provided for enhancing health care efficiency. 7. Results of this study cannot be generalized because there are large scale of deviation in case of workplaces with less than 300 full time workers, but B/C ratio reads 2.69 as a whole and 3.25 at workplaces with their own health care manager are higher than 1.63 at the workplaces manged by the agencies. Finally, all the benefit concerning health care services could not be quantified, measured and shown on the value of money. This is a reason that a considerable part of benefits are so underestimated. This is also thought that measurement tools should be developed for measuring benefits of health care services with a comprehensive quantification. in the future. It is also expected that efficiency of occupational health care services should be investigated using cost-effectiveness analysis.

In this study, we aim to design the architecture of the kV imaging system for tumor tracking in the dual-head gantry system and analyze its accuracy by simulations. We established mathematical formulas and algorithms to track the tumor position with the two-pair kV imaging systems when they are in the non-orthogonal positions. The algorithms have been designed in the homogeneous coordinate framework and the position of the source and the detector coordinates are used to estimate the tumor position. 4D XCAT (4D extended cardiac-torso) software was used in the simulation to identify the influence of the angle between the two-pair kV imaging systems and the resolution of the detectors to the accuracy in the position estimation. A metal marker fiducial has been inserted in a numerical human phantom of XCAT and the kV projections were acquired at various angles and resolutions using CT projection software of the XCAT. As a result, a positional accuracy of less than about 1mm was achieved when the resolution of the detector is higher than 1.5 mm/pixel and the angle between the kV imaging systems is approximately between $90^{\circ}$ and $50^{\circ}$. When the resolution is lower than 1.5 mm/pixel, the positional errors were higher than 1mm and the error fluctuation by the angles was greater. The resolution of the detector was critical in the positional accuracy for the tumor tracking and determines the range for the acceptable angle range between the kV imaging systems. Also, we found that the positional accuracy analysis method using XCAT developed in this study is highly useful and will be a invaluable tool for further refined design of the kV imaging systems for tumor tracking systems.

Purpose : To investigate the signal enhancement ratio by NOE effect on in vivo $^{31}P$ MRS in human heart muscle and liver. we also evaluated the enhancement ratios of different phosphorus metabolites, which are important in 31P MRS for each organ. Materials and Methods : Ten normal subjects (M:F = 8:2, age range = 24-32 yrs) were included for in vivo $^{31}P$ MRS measurements on a 1.5 T whole-body MRI/MRS system using $^1H-^{31}P$ dual tuned surface coil. Two-dimensional Chemical Shift Imaging (2D CSI) pulse sequence for $^{31}P$ MRS was employed in all $^{31}P$ MRS measurements. First, $^{31}P$ MRS performed without NOE effect and then the same 2D CSI data acquisitions were repeated with NOE effect. After postprocessing the MRS raw data in the time domain, the signal enhancements in percent were estimated from the major metabolites. Results : The calculated NOE enhancement for liver $^{31}P$ MRS were $\alpha-ATP\;(7\%),\;\beta-ATP\;(9\%),\;\gamma-ATP\;(17\%),\;Pi\;(1\%),\;PDE\;(19\%)$ and $PME\;(31\%)$. Because there is no creatine kinase activity in liver, PCr signal is absent. For cardiac $^{31}P$ MRS, whole body coil gave better scout images and thus better localization than surface coil. In $^{31}P$cardiac multi-voxel spectra, DPG signal increased from left to right according to the amount of blood included. The calculated enhancement for cardiac $^{31}P$ MRS were : $\alpha-ATP\;(12\%),\;\beta-ATP\;(19\%),\;\gamma-ATP\;(30\%),\;PCr\;(34\%),\;Pi\;(20\%),\;(PDE)\;(51\%),\;and\;DPG\;(72\%)$. Conclusion : Our results revealed that the NOE effect was more pronounced in heart muscle than in liver with different coupling to 1H spin system and thus different heteronuclear cross-relaxation.
