Purpose: Hyperdontia is a developmental disorder of the oral cavity. Mesiodens refers to the hyperdontia located between the maxillary central incisors. During the surgical procedure, the anesthetic method for pain control should be considered along with factors related to the surgery itself. The purpose of this study was to evaluate the effect of the impacted position of the mesiodens on the selection of sedation method and to suggest incisive foramen as a brief reference. Materials and Methods: This study included 126 patients who were scheduled for extraction of mesiodens. The selection criteria included patients with one palatally impacted inverted mesiodens accessible from the palatal gingival margin, and those with good cooperation potential in order to control for clinical information. Using cone beam computed tomography, vertical, horizontal, and palatal positional factors were measured, and the anesthetic method was determined by two examiners. The patients were grouped into vertical and horizontal groups based on the position of the incisive foramen. Data were statistically analyzed using the Mann-Whitney test, the chi-square test, and logistic regression analysis. Result: All positional factors differed between the outpatient and inpatient anesthetic groups. The vertical minimum distance from the alveolar ridge to the mesiodens (Va) and the minimum distance from the palatal surface to the crown tip of the mesiodens (Tc) were factors affecting the choice of anesthetic method. The distribution of the vertical and horizontal positional groups differed between the outpatient and inpatient anesthetic groups. Conclusion: The incisive foramen can be used as a brief reference to determine the appropriate anesthetic method. Referral for inpatient anesthesia may be a priority if they are in the V₂H₂ group with Va ≥5 mm, and Tc ≥6 mm, and outpatient sedation may be considered if they are in the V₁H₁ group with Va ≤1.5 mm, and Tc ≤2.5 mm.

The efficacy of the autotransfusion system is a reducing the need of intraoperative and postoperative transfusion in cardiovascular surgery. Between January 1990 and December 1991, we experienced 23 cases of autotransfusion using Haemonetic Cell Saver in cardiovascular surgery [Experimental group]. Another 13 cases which were taken similiar operations without Cell Saver during same period [Control group]. The amounts of blood transfused are 4.23 1.84 units in Control group, 2.82 1.84 units in Experimental group. Postoperatively, both groups showed decreased platelet counts, mild prolongation of prothrombin and partial thromboplastin time compred to preoperative value [P<0.001], but there were no significant differences between two group [P=NS]. Plasma hemoglobin was markedly increased in Experimental group compared with Control group [p<0.05]. In Experimental group, amount of average processed blood by Cell Saver was 700ml of which composition was hemoglobin 17mg/dl, hematocrit 50.0%, RBC 5,590,000/ml, WBC 7500/ml, and platelet 40,000/ml. The culture of the processed blood revealed no growth of the organisms. Conclusively, Cell Saver autotransfusion system is a simple, safe, and cost effective method especially in the cases associated with massive bleeding. However, it requires familiarity with system, gentle manipulation of suction tip, and careful selection of candidates to obtain maximal benefits .

Purpose: This study was conducted to verify the effects of an education program of restraints use on nurses' knowledge, attitude and nursing performance related to restraints use. Method: A quasi experimental study with a pre and post non-equivalent design was used. The subjects were nurses who met the selection criteria and worked in intensive care units of two university hospitals located at K-city, Gyeongbuk. Twenty nurses in A hospital were designated as the experimental group and 20 nurses in B hospital as the control group. Result: The first hypothesis which assumed that the experimental group would have higher scores of knowledge than the control group was supported(F=62.66, p=0.000). The second hypothesis which assumed that the experimental group would have lower scores of attitude toward using restraints than the control group was supported(F=23.77, p=0.000). The third hypothesis which assumed that the experimental group would have higher scores of nursing performance than the control group was supported(F=3.28, p=0.032). Conclusion: An education program for nurses' on the use of restraints needs to be introduced to decrease inappropriate use of restraints.

The purpose of this study was to assess the pain-relieving effect of iontophoretically applied prednisolone on the patients with temporomandibular joint (TMJ) pain. 30 TMJ pain patients participated in this study. Inclusion criteria for subject selection were 1) tenderness of TMJ on palpation and 2) visual analog scales (VAS) of above 20 mm. The patients with polyarthralgia, rheumatic arthralgia, and systemic diseases were excluded for this experiment. The patients were randomly assigned to one of three groups; (1) Group 1 for administration of 2% prednisolone, (2) Group 2 for administration of 1% prednisolone, and (3) Group 3 for administration of saline. Phoresor PM600(Motion Control Utah, U.S.A) was used for administration of drugs by iontophoresis. Baseline and post-medication pain levels were recorded by VAS, pressure pain threshold (PPT), and palpation index (PI). Post-medication data were compared with baseline data for each group. The results were as follows : 1. All the groups showed significant decrease of VAS scores after treatment. 2. PPT was significantly increase only in Group 1 and 2 not in Group 3. 3. PI was significantly decreased only in Group 1 and 2 not in group 3.

Purpose: The study was aimed to investigate the effects of warm fluid used during surgery on the patients' hypothermia prophylaxis and recovery after surgery. Methods: This data were collected from Jul. 13 to Nov. 31. 2009 at S hospital in M City. 60 patients who met the selection criteria were recruited in the study and divided into two groups. The warmed fluids were used for 30 patients in the experimental group, and the fluids in room air temperature were used for the others in the control group. Collected data were statistically analyzed using SPSS/win 18.0. Results: The body temperatures of the control group were significantly lower during surgery than those of the experimental group (p<.001). Shivering was significantly less occurred in the experimental group than the control group (p=.018). The experimental group used warmed fluids recovered faster than the control group. Conclusion: Warming fluid for the patients with general anesthesia was revealed to be effective in decreasing hypothermia during surgery, reducing shivering, helping recovery from the anesthesia. Further research is warranted to refine and apply this evidence in nursing practice.

It is very useful and important to see the status and change of necessary parts in a short period through selecting and observing the bioindicator continually to forecast and prepare the future. Especially, living things are so closely related to the environment that the indicator between the environment and living things shows close interrelationship. Also, the indicator related to environment provides information about representative or decisive environmental phenomenon and is used to simplify complicated facts. Considering wide range of background and application including various indicators such as the change-, destruction-, pollution-, and restoration of habitats, climate change, and species diversity, the closest category includes "environmental indicator," "ecological indicator," and "biodiversity indicator." The selection and use of bioindicator is complicated and difficult. The necessary conditions for the indicator selection are flexible and greatly depend on the goals of investigation such as the indicator for biological diversity investigation of specific area, the indicator for habitat destruction, the indicator for climate change, and the indicator for polluted area. It should meet many various conditions to select a good indicator. In this study, eleven selection standards are established based on domestic and overseas studies on bioindicator selection: species with clear classification and ecology, species distributed in geographically widespread area, species that show clear habitat characteristics, species that can provide early warning for a change, species that are easy and economically benefited for the investigation, species that have many independent individual groups and that is not greatly affected by the size of individual groups, species that is thought to represent the response of other species, species that represent the ecology change caused by the pressure of human influence, species for which researches on climate change have been done, species that is easy to observe, appears for a long time and forms a group with many individuals, and species that are important socially, economically, and culturally.
