For the assessment of changes in the bone architecture of the maxilla and mandible in renal osteodystrophy, 31 chronic renal failure patients who were undergoing hemodialysis therapy were selected. They were evaluated through clinical oral examination, radiographic and biochemical examination. The results were as follows: 1. In 17 cases (54.8%), there were evidences of bony change in jawbone. 2. The most common dental radiographic finding was decreased bone density (14 cases, 45.2%). 3. The second most common dental radiographic finding was total or partial loss of lamina alveolar dura (11 cases, 35.5%). 4. The third most common dental radiographic finding was total or partial loss of inferior canal wall (8 cases, 25.8%). 5 cases showed evidences of bony change only in jawbone, and 5 cases only in hand, and 12 cases in both. 6. Serum creatinine, urea nitrogen and alkaline phosphatase values in hemodialysis group were much higher than in control group. 7. There were statistically significant correlation between bone density and lamina dura, and inferior alveolar canal wall.

Purpose: The purpose of this study was to describe the experiences of job satisfaction in clinical nurses. Methods: Data was collected from three focus groups composed of 17 hospital nurses. Each focus group had an interview for an average of two and a half hours with the guidance of researchers. The main question was 'how do you describe your lived experience of job satisfaction as a clinical nurse?' Qualitative data from the field notes and transcribed notes were analyzed using a grounded theory methodology developed by Strauss and Corbin. Results: The core category of experience of job satisfaction in clinical nurses was identified as 'Finding success.' Supportive interpersonal relationships and environment affected this category. In the process of attaining job satisfaction through finding success, the participants were using four interactional strategies such as giving meaning, finding self-esteem, extending the horizon of life, and strengthening self-capability. The dimensions of job satisfaction in clinical nurses were the sense of achievement, stability, and pride. Conclusion: The results of this study yields very useful information for nursing mangers to design a program which enhances job satisfaction of clinical nurses based on interactional strategies.

Purpose: This study aimed at finding the optimal input variables of the artificial neural network-based predictive model for the optimal controls of the indoor temperature environment. By applying the optimal input variables to the predictive model, the required time for restoring the current indoor temperature during the setback period to the normal setpoint temperature can be more precisely calculated for the cooling season. The precise prediction results will support the advanced operation of the cooling system to condition the indoor temperature comfortably in a more energy-efficient manner. Method: Two major steps employing the numerical computer simulation method were conducted for developing an ANN model and finding the optimal input variables. In the first process, the initial ANN model was intuitively determined to have input neurons that seemed to have a relationship with the output neuron. The second process was conducted for finding the statistical relationship between the initial input variables and output variable. Result: Based on the statistical analysis, the optimal input variables were determined.

Until now, considerable progress has been made in the application of range finding techanique performing direct 3-D measurement from the object. However, ther are few use of the method in the area of the application of material handing. We present a range finding vision system consisting of static and dynamic range finders to automate a reclaimer used for material handling. A static range finder detects range data of the front part of the piles of material, and a height map is obtained from the proposed image processing algorithm. The height map is used to calculate the optimal job path as features for required information for material handling function. A dynamic range finder attached on the side of the arm of the reclaimer detects the change of the local properties of the material with the handling function, which is used for avoiding collision and detecting the ending point for changing direction. the developed vision systm was applied to a 1/20 simulator and the results of test show that it is appropriate to use for automating the material handling.

이 논문에서는 단말기 기반 시스템에서 경로를 탐색할 때 탐색비용을 줄이고, 경로탐색의 질을 높이기 위해 동적 휴리스틱을 제안한다. 동적 휴리스틱이란 고정된 정보가 아닌 서버로부터 지속적으로 전송받는 휴리스틱으로, 교통정보를 계산한 데이터이다. 서버 기반의 경로탐색 서비스는 서버에서 경로를 탐색하여 결과를 클라이언트에 제공하지만, 제안하는 방법은 휴리스틱 정보만을 클라이언트에 전송하고 이를 활용하여 경로탐색을 하게 된다. 이 논문에서는 제안하는 동적 휴리스틱을 적용하기 위해 새로운 알고리즘을 제안한다. 제안하는 동적 휴리스틱은 지도를 그리드로 나누고, 각 그리드는 구역내 간선들의 최저속도 정보를 가진다. 그리드의 최저속도가 기준치에 미달되면 해당 그리드를 제거하고 경로를 탐색한다.

Purpose: To evaluate the histologic effect(LM and EM findings)of nonablative LASER and thermal energy on knee joint capsule of rabbit. Material and Methods: The nonablative LASER and thermal energy was applied to the rabits(average age 36 weeks, weight 5 ㎏). There were divided into 4 groups with 6 rabbits in each. The group I received 6 watts of LASER, group Ⅱ 12 watts of LASER, group Ⅲ 60° of thermal energy, and group Ⅳ 70° of thermal energy. The histologic study included H-E, Massons trichrome stain and electron microscopy at immediate, 3 weeks and 6 weeks after operation. Results: The histologic finding in immediate after operation was shown a fibrous degeneration of collagen on all groups and related to the energy level. The histologic finding after 3 weeks showed fibrosis and this fibrosis related the level of energy. Especially the group IV was shown flattening of capsule and deep fibrosis. The histologic finding after 6 weeks was shown marked recovery of collagen arrangement and capillary proliferation in group Ⅰ,Ⅱ and Ⅲ. But in the group Ⅳ not recovered. Conclusion: The nonablative LASER or thermal energy can cause degeneration, fibrosis and contracture of joint capsular collagen.

We report the seasonal prevalence of the mycoplasmal pneumoniae of swine (MPS) in slaughter pigs from July of 1999 to June of 2000. Gross finding of lung lesion observed and examined by dot-ELISA. In gross finding of lung lesion from 750 pig samples, 465 (62.0%) was MPS, and 129 (17.2%) was single or double infection with actinobacillosis and pasturellosis. However, 156 (20.8%) had no lesion. In seasonal detection, the prevalence was found to be winter (69.5%), autumn (63.5%), summer (60.0%) and spring (54.7%) in orderly frequency. In dot-ELISA, the result was showed the positive reaction (x16>titre) with 58.0% and negative (x4

A deterministic tuberculosis model for theoretically assessing the potential impact of the combined effects of case detection in the presence of treatment is formulated. The qualitative features of its equilibria are analyzed and it is found that the disease-free equilibrium may not be globally asymptotically stable when the reproduction number is less than unity. This disease threshold number is further used to assess the impact of active TB case finding alone and in conjunction with treatment. A critical threshold parameter ${\Theta}$ say for which case detection will have a positive impact is derived. Using the Centre Manifold theory, the model may exhibit the phenomenon of backward bifurcation (coexistence of a locally stable endemic equilibrium with a stable disease-free equilibrium) when the reproduction number is less than unity. It is shown that the possibility of backward bifurcation occurring decreases with increase case detection. Graphical representations suggest that increase in case finding accompanied by treatment of detected TB cases, result in a marked decrease of TB cases (both latent and active TB).
