Changing concepts of health care, are stimulating the demand for health care, thereby orienting society to health care rights to such an extent that they are deemed as fundamental ones inalienable to man. Concomitantly, qualitative as well as quantative improvement is being sought in the nursing service field. Today, efforts are being made in various areas, especially to qualitatively improve nursing services. A second issue concerns proper staffing. It is important to study staffing, in as much as it continues to be the most persistent and critical problem facing hospital nursing administrators today. It involves quantity, quality, and utilization of nursing personnel. A great deal of attention has been focused on this problem since mid 1930's when nursing services began to be felt as an important segment of hospital operation representing the largest single item of hospital budgets. Traditionally, the determination and allocation of nursing personnel resources has relied heavily on gloval approaches which make use of fixed staff-to-patient ratios. It has long been recognized that these ratios are insensitive to variations between institutions and among individual patients. Therefore, the aim of this thesis is to point to the urgent need for the development of methodology and criteria suited to the reality of Korea. The present research selected one place, the W Christian Hospital, and was conducted over a period 10 days from January, and nurses who were them on duty in their unit. The total num-her of patients surveyed was 1,426 and that of 354. The research represents many variables affecting the direct patient care time using the result from the direct observation method, then using a calculation method to estimate the relationship between the patients care time and selected variables in the hospital setting. The amount of direct patient care time varies with many factors, such 89 the patients age. diagnosis and time in hospital. Differences are also found from hospital, clinic to clinic, ward to ward, and even shift to shift. In this research, the calculation method of estimating the required member of nursing staff is obtained by dividing the time of productive patient care activity(with the time of patient care observed), by the sum of the productive time that each the staff can supply, i.e., 360 minutes, which is obtained by deducting the time for personal activities. The results indicate a substantial difference between the time of productive patient care observed directing and the time of the productive patient care estimated using calculating method. If we know accurately the time of the direct patient care on a shift, there required number of staff members calculated if the proper method can be determinded should be able the time of the direct patient care be estimated by the patient classification system, but this research has shown this system to be in accurate in Korea. There are differences in the recommended time of productive patient care and the required number of nursing staff depending upon which method is used. The calculated result is not very accurate, so more research is needed on the patient classification system.

Glioma is one of the common types of brain tumors starting in the brain's glial cell. These tumors are classified into low-grade or high-grade tumors. Physicians analyze the stages of brain tumors and suggest treatment to the patient. The status of the tumor has an importance in the treatment. Nowadays, computerized systems are used to analyze and classify brain tumors. The accurate grading of the tumor makes sense in the treatment of brain tumors. This paper aims to develop a classification of low-grade glioma and high-grade glioma using a deep learning algorithm. This system utilizes four transfer learning algorithms, i.e., AlexNet, GoogLeNet, ResNet18, and ResNet50, for classification purposes. Among these algorithms, ResNet18 shows the highest classification accuracy of 97.19%.

본 논문에서는 은닉 마코프 모델을 이용하여 정상인과 정신분열증 환자의 뇌파에 대한 새로운 자동 판별 방법을 제안하였다. 특징 파라미터로는 통계적 정상구간에 대한 분산과 알파파, 베타파, 세타파의 전력비를 이용하였다. 실험 결과, 정상인의 경우에는 90.9％, 정신분열증 환자의 경우에는 90.5％의 높은 판별 정확성을 보였으며 이는 제안한 시스템이 복잡한 신호처리과정을 이용하는 시스템보다 효과적임을 알 수 있다. 따라서, 은닉 마코프 모델이 뇌파와 같은 복잡한 생체신호의 분석과 판별에 사용될 수 있으며 제안한 방법이 임상적인 전단에 상당한 도움이 될 것으로 기대된다.

The present study was conducted to examine the degree of variation in length-of-stay (LOS) among health care institutions participating in 17 diagnosis-related groups (DRGs) payment system and to find out hospital characteristics affecting the variation. Electronic medical claims data for treatments of severity classification '0' of 17 DRGs provided for two $years(2003{\sim}2004)$ were collected. For each DRG, the degree of variation in average LOS among health care institutions were analyzed using the random effect model. For DRGs showing significant differences in LOS, multiple regression analyses were performed to find out factors associated with LOS. Significant variations in LOS were observed 9 DRGs including unilateral/bilateral lens procedures, adult/child tonsilectomy, other anal procedures, bilateral adult/child herniorraphy, unilateral child herniorraphy, and hysterectomy, and hysterectomy using laparoscopic procedure. Among the 9 DRGs, five DRGs were selected to investigate the factors explaining for the variation. It was observed that the location of institution was significant predictors for all five DRGs. Within the same DRGs, LOS was significantly shorter among the institutions located in Seoul than those in other areas. As compared to clinics, hospitals and general hospitals/tertiary care institutions showed significantly longer LOS for DRGs of lens procedures, tonsilectomy, and other anal procedures. It is recommended that the institutions located in other than Seoul area benchmark the strategies of the institution in Seoul in efficiently managing LOS. Also, significant variation within the same severity classification such as other anal procedures implies the imminent need for improvement of patient classification system.

Atrophic alveolar ridge of maxillary anterior area is commonly observed after the extraction of teeth in patients with severely compromised periodontal disease, causing difficulties with implant placement. Successful esthetics and functional implant rehabilitation rely on sufficient bone volume, adequate bone contours, and ideal implant positioning and angulation. The present case report categorized the ridge augmentation techniques using guided bone regeneration (GBR) on the maxillary anterior site by Seibert classification. Case I patient presented for implant placement in the position of tooth #11. The alveolar ridge was considered a Seibert classification I ridge defect. Simultaneous implant placement and GBR were performed. Eight months after implantation, clinical and radiological examinations were performed. Case III patient presented with discomfort due to mobility of the upper maxillary anterior site. Due to severe destruction of alveolar bone, teeth #11 and #12 were extracted. After three months, the alveolar ridge was considered a Seibert classification III ridge defect. A GBR procedure was performed; implantation was performed 6 months later. Approximately 1-year after implantation, clinical and radiological examinations were performed. During the whole treatment period, healing was uneventful without membrane exposure, severe swelling, or infection in all cases. Radiographic and clinical examinations revealed that atrophic hard tissues and buccal bone contour were restored to the acceptable levels for implant placement and esthetic restoration. In conclusion, severely resorbed alveolar ridge of the maxillary anterior area can be reconstructed with ridge augmentation using the GBR procedure so that dental implants could be successfully placed.
