Magnetic Resonance Imaging(MRI) is one of the most expensive and sophisticated diagnostic tool and has been hailed as the most exciting event in medical imaging "since the introduction of X-rays", but a major disadvantage, high cost, is coming into focus especially in our country. To determine the status of distribution of MR imagers in Korea and to serve as a basic material for an efficient utilization of this Imaging machine, a retrospective survey of nationwide and regional(3 hospitals in Pusan) installations was performed. The results were as follows : 1. As of April 30, 1991, a total of 33 MRI units(24 for superconducting, 6 for permanent and 3 for resistive units) were set up and operated. 91% of the units were distributed in big cities with no one installation in 7 provinces among 12 provinces in our country. 85% of the units were imported. 2. Although 42.4% of the units were operated in Seoul, Taejeon had the best condition for the distribution of this imaging machine per population, hospital, and bed in Korea. 3. In Pusan : a) 5 units were operated with all superconducting magnet and medium magnetic field in type of machine. b) 80.1 % of the examinations were central nervous system(CNS). c) MRI examination occupied 1.4% of all radiographic examinations and the patients referred from other hospitals were composed of 23.4%% of all patients. 4. The average days under operating of MRI unit a week in Puasn were higher(5.5) than that of Seoul(4.5), but the average number of examinations and hours a week and a day, respectively(33, 8.4), was less than that of Seoul(57, 12.9). 5. The patients with positive MRI findings in a hospital(B) in Pusan was 74.5% on an average.

A systematic review of the literatures was conducted to evaluate the effect of clinical practice guideline. The 77 studies were identified from a computerized search of published research on MEDLINE, Science-Direct and Blackwell synergy from January, 1997 to October, 2007. The main search terms were "clinical practice guideline" and "effectiveness", "clinical practice guideline" and "impact", "clinical practice guideline" and "evaluation". These studies were assessed the Quality twice by one Qualified expert and converted into weighted scale. The 63 studies were eligible inclusion criteria and subdivided into type of effect. Final indicator using for policy effect of clinical practice guidelines were classified as 4 categories; "improvement of outcomes" in 81 studies, "betterment in practice patterns" in 68 studies, "rationalization in resource utilization" in 84 studies and "cost containment" in 31 studies. The vote-counting method, one of meta-analysis method, was applied to summarized the effect of clinical practice guidelines and test statistically. From results of meta analysis, all indices were statistically significant. In conclusion, this meta-analysis showed that introduction of clinical practice guidelines were resulted positive outcomes in health policy.

Ethylene oxide ($C_2H_4O$, EtO) is used as a raw material for the production of ethylene glycol and other industrially important material such as ethanolamines and also used as a disinfecting agent. It is applied for gas-phase sterilization of thermally sensitive medical equipment, and for processing of storage facilities as a mixture with fluorinated hydrocarbon. In this perspective, accurate determination of the mole fractions of components in the liquefied gas mixture is required for the quality control and safety of production and use. Each component of the liquefied gas mixture has different chemical and physical properties such as vapor pressure and boiling point. Therefore, we can suppose that analytical results can be different according to the introduction method for the gas phase of upper layer, or for the liquid phase of lower layer in gas cylinder. In this study, we designed a new on-line sample injection device for the liquefied gas mixture in liquid or gas state, and applied to the analysis of liquefied gas mixture of ethylene oxide and fluorinated hydrocarbons by GC/AED (gas chromatograph-atomic emission detector). We studied performance of AED, and effect of sample introduction and selected wavelength to the accuracy and repeatability of analytical results.

After the introduction of National Medical Insurance in 1989, the medical demand has rapidly increased. The impact of increased medical demand was followed by an increase in the number of claims in need of review. We studied a new, fair method for reducing the number of claims reviewed. We analysed 90,583 outpatient claims submitted between September and October; claims were made for services given August of 1994. We finally suggested a screening system for claims review using a statistical method of discriminant analysis of the medical costs. The results were as follows. 1. In the cut-off group, age, days of medication, number of hospital or clinic visits, and total charge were significantly high. The cut-off rates according to the hospital-type and existence of accompanied disease were significantly different 2. According to ICD, the cut-off rate was highest in peripheral enthesopathies and allied syndromes(20.76%), lowest in acute sinusitis(0.93%). The mean charges were significantly different according to ICD and existence of cut-off. 3. We build discriminant functions by ICD with such discriminant variables as patient age, sex, existence of accompanied disease, number of hospital or clinic visits, and 9 detailed hospital or clinic charges included in claim. 4. We applied the discriminant function for screening those claims that were expected to be cut-off. The sensitivities comprised from 40% to 70%, and specificities from 70% to 95% by ICD. Acute rhinitis had highest sensitivity(100.00%) and other local infections of skin and subcutaneous tissue had highest specificity(98.45%). The expected number of cut-off was 17,762(19.61%). The total sensitivity was 49.62%, the total specificity was 82.57% and the error rate was 19.66%. We lacked economic analysis such as cost-benefit analysis. But, if the new method of screening claims using discriminant analysis were applied, the number of claims in need of review will reduce considerably.

Since radon is an inert gas and is a monoatomic molecule, the size of one particle represents the size of an atom, which means that it has a radius of approximately 1 to 100 nm. Therefore, if the mask has a radius smaller than the size of general fine dust and ultra fine dust, but it is possible to block the inhalation of radon more than a certain amount, it is considered that the exposure through the inhalation of radon can be reduced through normal indoor wear. Accordingly, we would like to find out the radon blocking effect of a mask worn in everyday life. Looking at the reduction rate of radon for each mask, cotton masks decreased by 33.45%, medical masks by 33.50%, KF 80 masks by 35.12%, and KF 94 masks by 37.72%. It was found that the radon blocking effect of the cotton and medical masks was somewhat inferior to that of the KF mask, but the difference was not so great that the introduction of radon into the air could be blocked to a certain level by wearing a mask.

This study examined Cheon SunEui(全循義)'s lineage, life, ChimGuTaekllPeonJip(鍼灸擇日編集) and SikRyoChanYo(食療纂要)'s subjectmedical history. Cheon SunEui(全循義)'s position underestimated that it's associated with the reality of politics in the early years of the Joseon dynasty medical history. Accordingly, Cheon SunEui(全循義)'s the healing art and studies remain poorly characterized. To understand the role of Cheon SunEui(全循義)'s studies, we examined that his lineage and life. We made a complete translation Cheon SunEui(全循義)'s ChimGuTaekllPeonJip(鍼灸擇日編集) introduction and confirmed importance alternative choice in the practice of acupuncture and moxibustion. We also identified that SikRyoChanYo(食療纂要) introduced hothouse methods using Korean paper and ondol, food store and fish store methods. is not too much to say that this book is one of the diet of our time. These results demonstrated that Cheon SunEui(全循義)'s life and literary work feel keenly the necessity of study in korea medical history. Because of the actual politics place estimate, Cheon SunEui(全循義)'s life and science underestimate. However, his books excavated. Old values cut red tape, following studied realized about his medical art and medical ideas.

Pyropheophorbide and pheophorbide-photosensitizers as chlorin analogues are promising new compounds for PDT because the chlorin analogues are activated with much longer red light at > 670nm and produce less long-term normal tissue phototoxicity than Photofrin. The various chlorin derivatives can be obtained by moditying peripheral substituted group among which meso-H, vinyl group and exocyclic ring are the most active positions. These characteristics prompted us to introduce various groups for constructing modified pyropheophorbide and pheophorbide a compounds. A stereospecific introduction of various double bonds at 3-position was performed to methylpheophorbide a to give a long hydrophobic moiety and cyclic derivatives. Chlorin-C$_{60}$ dyad and chlorin- $C_{60}$-porphyrin triad also were easily prepared by the reaction of terminal aldehyde of methyl pyropheophorbide a. For the reaction on meso $\delta$-position bromination and Vismeier formylation can occur. N,N-dimethylaminoacrolein also reacted on $\delta$-position and was cyclized to isobacteriochlorin, but other modification has not been succeeded. Exocyclic keto function was also modified to give purpurin derivatives, bicyclic and spiro compounds. In this presentation we report a series of modified pyropheophorbide and pheophorbide a derivatives.s.

Purpose: The purpose of this study was to remind the importance of research ethics in research and publication, and to suggest the direction of research ethics by taking examples of research ethics recently implemented by KJFHC. Research design, data and methodology: With reference to the research of existing researchers, why research ethics is important, what are the violations of research ethics, and the efforts of the editorial committee of KJFHC to strengthen research ethics are presented as an example. Results: It is a reality that the concept of research ethics is becoming more complex and important with the introduction of various new academic fields. At this point in time, researchers need to pay more attention to the easily overlooked concept of research ethics. In research ethics, the most important thing is not punishment through monitoring and supervision, but prevention activities of research ethics that can prevent research misconduct before it occurs. As a preventive activity for research ethics, it can be said that the most important is the establishment of a systematic education system and active educational activities of universities and related institutions. Conclusions: This study avoids the general status and solutions for research ethics, and explains the case of the actual academic journal KJFHC and suggests alternatives.
