Purpose: The pathology of peri-implantitis is still not fully understood and there have been recent challenges to the consensus on its aetiology and pathology, especially in comparison with periodontitis. The assessment of biomarkers allows a comparison of the pathology of these diseases. The aim of this systematic review was to answer the research question: "Is there a difference in the biomarkers associated with peri-implantitis compared with periodontitis in adult humans?" Methods: Electronic databases were searched and screened, and a manual search was also undertaken. The inclusion criteria were adults with peri-implantitis who had been compared to adults with periodontitis with the outcome of biomarkers assessed via biopsies or crevicular fluid samples in primary or secondary care settings, as recorded in case-control, case series and retrospective, prospective and cross-sectional observational studies. Two reviewers independently screened titles and abstracts and assessed full text articles for eligibility and inclusion. Both reviewers independently extracted data and assessed risk of bias. Differences in biomarker levels were the primary outcome and a narrative review was undertaken due to the heterogeneity of studies. Results: In total, 2,374 articles were identified in the search, of which 111 full-text articles were assessed for eligibility and 13 were included in the qualitative synthesis. Five of the 13 included studies were deemed to be at high risk of bias, with the others having moderate risk. All studies were cross-sectional and performed at university hospitals. Nine of the 13 included studies found significant differences in the levels of biomarkers or their ratios between periimplantitis and periodontitis. Four of the studies found no significant differences. Conclusions: Within the limitations of the included studies, it appears that there may be a difference in biomarker levels and ratios between peri-implantitis and periodontitis, suggesting that these disease processes are somewhat distinct.

This study was conducted to identify the problems related to operation of the committee system in university hospitals and to propose the direction for reforming it. Data were collected by surveying 138 working-level administration managers of committees from 12 university hospitals in Seoul in October, 1995. The results were as follows: 1. The purposes of the committee were to promote the reasonable dicision making in the hospitals, to satisfy the requirement of Hospital Accreditation Program and, to execute the administrational instructions in due order. The sort of job which was charged of chairmen and the majority of committee member was doctor. 2. The committees which were to be held the meeting frequently in a year were general management committees(8.25 times/year). But in case of operation rate, medical care-related committees showed the most frequent meeting(90.15%). Most of committees made the regulations and reported the results of their meeting to the CEO of their hospitals by written documents. 3. Most doctors thought the medical care-related committees useful. Medical technicians regarded education and research-related committees as useful, while administrators favored the general management committees. 4. The factors related to the perceived performance of the committee were the kind of job, the class of job and the kind of committee. Also, the perceived performance of the committee was positively related to the usefulness in efficient management of work, and negatively to uncertainties in responsibility and a nominal role of the committee. 5. Most of the respondnts thought that the concern of the top manager about the committee was the most important factor for the improvement of committee system at hospitals. They also regarded that formalization of the objectives and regulation rule and composition of committees with members which work in various fields as essential. Further studies on the organizational and operational cjharacteristics which include general hospitals in various areas are required.

This paper is to investigate a more detailed method for the diagnosis of anterior wall of the stomach by making a comparative study with several hospitals. It has been true that there have been hospitals, that have not examined anterior wall of the stomach. However, it is very important for us to examine anterior wall of the stomach for an carly detection of gastric carcinoma. The results of th study are as follows : 1. Frequency of occurrence of the early gastric carcinoma for the anterior wall were 50 cases and 34 cases for the posterior wall out of 84 cases. 2. Only a hospitals have examined the anterior wall of stomach. 3. In case of operation, only a hospitals have used two techniques at for same time single and double contrast studies. 4. Only cue hospital used a compression pad and three hospitals hod only filing state images taloen. 5. In general, 1 chest of film was used and the number of exposures rouged from 1 to 2 times. Lesions on the anterior wall of the stomach can be shown by the combination of prone single com-pression and supine double contrast radiographs. Therefore, the conclusion came to the result that the prone single compression and supine double contract technique of the anterior wall are Indispensable methods to the routine check of the stomach.

Importance of Today's diffusion of integrated hospital information systems is that various and huge amount of data is being accumulated in their database systems. Many researchers have studied utilizing such hospital data. While most researches were conducted mainly for medical diagnosis, there have been insufficient studies to develop medical care cost prediction model, especially using machine learning techniques. In this research, therefore, we built a medical care cost prediction model for cancer patients using CBR (Case-Based Reasoning), one of the machine learning techniques. Its performance was compared with those of Neural Networks and Decision Tree models. As a result of the experiment, the CBR prediction model was shown to be the best in general with respect to error rate and linearity between real values and predicted values. It is believed that the medical care cost prediction model can be utilized for the effective management of limited resources in hospitals.

Purpose: Clinical laboratory of hospital has been demanded to extension or relocation regarding with the test number increase and analyzer development. Space area criteria per test numbers, lab functions, hospital bed and lab staffs are needed for draft space programing. So, the purpose of this study is to provide the space area guideline of clinical laboratory for space calculation in planning and design the spatial environment. Methods: Literature review has been used in checking the standards and guidelines. And questionnaire surveys to laboratory supervisors in hospitals have been conducted for the data collection. 60 answers have been analysed statistically by MS Excel program. Results: The result of this study can be summarized into three way calculations. The first one shows that the basic standard workspace and distance is applied in lab design. The second one shows that average space area criteria resulted from case studies is applied by 19㎡ per one staff, 0.9~1.0㎡ per one bed, and lastly linear length calculation of workbenches and analyzers on the bench top and floor mount, is multiplying it by the sum of the counter depth plus aisle width. Implications: In updating the space area calculation guidelines, it is necessary to cooperate with medical staffs and designers.

Purpose: It seems obvious that the hospital structures become more large-sized and tall-risen in Korea today. Nothing is more influential than the vertical core plan on the movements of various people in such large-tall hospitals. The present paper, therefore, aims to study on the efficient hospital core space paying first attention to patients by analysing the data on relations between/among department layouts of vertical and horizontal movements. Methods: This study sampled representative 14 hospitals and drew their degrees of data importance on the basis of precedented relative studies. This study also analysed their placements on the blueprint and made confirmations of their arrangements through their homepage on line. Actual visits were made to make sure of the spacial connections between/among departments in the hospitals as well. Results: Even in emergency case in need for vertical movements, the central main core spaces are usually used, which is because special vertical transportation systems are not provided. In these cases, the main core spaces are very important for those who have to move vertically and/or horizontally according to the locations and types of main cores. While special lifts or dumbwaiters are prepared to install for the important articles, such as samples of pathology department, most patients should share with regular visitors the elevators not separated visually and spatially from them. Implications: Vertical core plans are greatly dependent on the ward types and hospital styles. This study is hopefully expected to contribute itself to the standard setting-up of comfortable and quick vertical core system operations for patients.

The aim of this study is to analyze the variations among hospitals and hospital groups in resource use and procedures of diagnostic and therapeutic process, such as laboratory tests, radiologic examinations, tissue diagnosis, timing of surgery after admission, the time required for operation. The study was performed for five procedures including cesarean section (C/S), appendectomy, cholecystectomy, cataract extraction, and pediatric pneumonia. The 2,316 subjects were selected from medical insurance claims list, and from this list 413 cases were sampled for medical record review. The patterns of resource utilization and process of treatment were described according to hospitals and characteristics of hospital groups. The major results were as follows : 1. The numbers of laboratory and radiologic tests showed significant difference among hospitals and hospital groups. In case of hospital groups, we could find tendencies of more tests with increasing hospital bed size. 2. In general, the proportion of operative cases evaluated by tissue diagnosis postoperatively among all operations ranged from 28.3% to 100%. The proportion varied among hospital groups, of which general hospital A group(more than 15 specialty) showed the highest proportion. 3. Post-admission delay until operation and the time required for operative procedure were not invariable among hospitals and hospital groups. The duration of operation in tertiary hospitals was slightly shorter than general hospitals, with varying statistical significance. We could find that probably there were differences of quality among hospitals in some components of procedures, which suggested that the implementation of quality assurance activities would be mandatory. In this study, we simply described the patterns of resource utilization and some features of clinical process, with institution of the need for advanced studies with in-depth analyses for each component of diagnosis and treatment procedures.
