  • This paper aims to compare the effects of two teaching methods, the discovery-observational(DO) and the expository-observational(EO) instructions, on students learning interest in the life cycle of fruit fly. The subjects, 463 third-graders from two elementary schools in Changwon City, were divided into two groups, the DO group and the EO group. After the instruction on the life of the flies in two different teaching ways, a questionnaire with 13 items was devised regarding the students' interest, and the subjects were asked to respond to it. The results reveal that the general mean score of the DO group is higher than that of the EO group. Also, the DO group obtains the higher mean score in each item, except two items about knowledge learning. The differences of the mean scores of the two types, general as well as item-individual, between the two groups are statistically significant. This suggests that the class about the life cycle of living creatures easily getatable and observable, such as fruit flies, should be student-centered investigatory one, where students themselves collect them and observe the process of their growth and whole cycle.

  • Background: The postoperative pain in children and adolescents is most commonly managed by intramuscular injections of NSAIDs or opioids. This approach may result in fluctuating plasma drug levels and cycles of pain, comfort, and sedation. Patient-controlled analgesia(PCA) is a method of analgesia administration that consists of a computer-driven pump with a button that the patient may press to administer a small dose of analgesic drug. Materials & Methods: Forty ASA physical status 1 or 2 children and adolescents were divided into two groups. In the PRN group, patients received intramuscularly diclofenac(Valentac$^{(R)}$) on a p.r.n. basis. The PCA group patients received a mixture of nalbuphine and ketorolac by WalkMed$^{(R)}$PCA infusor. Analgesic efficacy was evaluated with NRS(numerical rating scale) and Faces Pain Rating Scale. The side effects were evaluated. Results: The patients of PCA group had less pain than those of PRN group. Complications were similar in both group. Conclusions: PCA with nalbuphine and ketorolac is a safe and effective methods of pain relief in children and adolescents after surgery, and is better accepted than intramuscular injections.

  • Purpose: This study was performed to identify effects of pneumoperitoneum on hemodynamic changes of hypertensive patients undergoing laparoscopic colectomy under general anesthesia. Methods: Data collection was done from January 2 to June 10, 2008. Seventy-six patients, including 38 hypertensive patients, who had taken antihypertensive drugs more than 1 month and 38 normotensive patients undergoing laparoscopic colectomy were enrolled in this study. The hemodynamic parameters were heart rate (HR), mean arterial pressure (MAP) and cardiac output (CO) which were measured 7 times from before induction of anesthesia to 5 min after deflation of the pneumoperitoneum. Collected data were analyzed using Repeated Measures ANOVA and Bonferroni comparison method. Results: HR in the hypertensive group was significantly decreased at deflation of the pneumoperitoneum and 5 min after deflation of the pneumoperitoneum (p=.012). MAP in the hypertensive group was not different from the normotensive group (p=.756). CO in hypertensive group was significantly lower than normotensive group (p<.001) from immediately after pneumoperitoneum to 5 min after deflation of the pneumoperitoneum. Conclusion: The results indicate that pneumoperitoneum during laparoscopic surgery does not lead to clinically negative hemodynamic changes in heart rate, mean arterial pressure or cardiac output of hypertensive patients, who have taken antihypertensive drugs for more than 1 month.

  • We reviewed 30 patients with tetralogy of Fallot who had underwent transannular patch reconstruction of the right ventricular outflow tract from January 1990 to May 1993. The patients were divided into two groups according to the approaching pattern for the corrective surgery: 12 patients[aged 11 months to 4 years; mean age, 2.3 years] in transatrial group who were repaired by transatrial-transpulmonary approach; 18 patients[aged 13 months to 6 years; mean age, 3.2 years] in transventricular group who were repaired by transventricular approach. The incidence of postoperative right bundle branch block was not statistically different between two groups. With follow up from 3 months to 32 months after operation, none in transatrial group revealed a remnant RVOT stenosis over 50mmHg or tricuspid regurgitation more than grade II with 2D-echocardiography, but two cases[7.7%] in transventricular group revealed these complications. Early postoperative death was 4 cases[13.3%] which all belonged to transventricular group. In conclusion successful repair of tetralogy of Fallot can be accomplished in most patients by transatrial-transpulmonary approach and we can anticipate better results by this approach in terms of postoperative right ventricular function and arrhythmia than conventional transventricular approach.

  • PURPOSE. The aim of this study was to evaluate whether there is any typical deformation pattern existing in complete denture when it was dried by using the 3D scanner and surface matching program. MATERIALS AND METHODS. A total of 28 denture bases were fabricated with heat curing acrylic resin (each 14 upper and lower denture bases), and 14 denture bases (each 7 upper and lower denture bases) were stored in the water bottle (water stored), and another 14 denture bases were stored in the air (dry stored). Each specimen was scanned at $1^{st}$ day after deflasking, $14^{th}$ day after deflasking, and $28^{th}$ day after deflasking, and digitalized. Three dimensional deformation patterns were acquired by comparison of the data within storage group using surface matching program. For evaluating differences between groups, these data were compared statisticallyusing Kruskal Wallis and Mann Whitney-U test (${\alpha}$=.05). RESULTS. When evaluating 3D deformation of denture base, obvious deformations were not found in maxillary and mandibular water storage group. However, in dry stored group, typical deformation pattern was detected as storage time passes. It occurred mostly in first two weeks. Major deformations were found in the bilateral posterior area in both maxillary and mandibular group. In maxillary dry stored group, a statistical significance was found. CONCLUSION. It was proved that in both upper and lower denture bases, dry storage caused more dimensional deformation than water storage with typical pattern.

  • The purposes of the study, based on the social comparison theory, were 1) to examine the body image and the body distortion of the late adolescent through the attitudinal and perceptual measurement of the body image and to examine the self-esteem, 2) to examine the difference of the clothing behaviors depending on the level of the body image, the body distortion and the self-esteem, 3) to examine the difference in the clothing behavior, the body image and the self-esteem according to sex. The sampling method was a convenient sampling and the subjects were 137 undergraduate students in Chungnam national University. The results of this study were as follows : The results of analysing the factors to the response of attitudinal body image emerged three factors (appearance interest, weight concern, and body satisfaction). The results of analysing the response of the clothing behavior showed four factors (fashion interest, psychological dependence of clothing, conformity to clothing, and exhibitionism of clothing). The positive group to the body image showed more interest in the fashion and had the tendency of depending on the clothing psychologically, and also showed that the group revealed much exhibitive attitude by using the clothing. The group of perceiving the face rather correctly tends to do the conformity behaviors, but the group distorting the shoulder width wider than tends to reveal more conformity behaviors. The group with the higher self-esteem had little interested in the fashion and also did the conformity behaviors slightly.

  • Background: Primary hyperhidrosis is a disorder of excessive sweating, which shares several features with anxiety disorders and has a negative impact on a patient's quality of life. Oral glycopyrrolate is one of the treatments available. There are a few published studies on the use of glycopyrrolate given orally in the treatment of hyperhidrosis. Methods: Thies is study was a review of case notes in a series of 36 patients with primary hyperhidrosis. We made a comparison between the Keller's scale score of a pre-glycopyrrolate medication group and the Keller's scale score f a post-glycopyrrolate medication group. The Milanez de Campos score, Short Form_36 (SF-36) score, Beck Depression Inventory (BDI) score, Beck Anxiety Inventory (BAI) score, and autonomic nervous system (ANS) scale score were also compared between the two groups. Results: In the post-glycopyrrolate medication group, there were declines in Keller's scale, and Milanez de Campos scale score and BAI score (P < 0.001). In addition, there were increases in SF_36 score in the post-glycopyrrolate medication group (P = 0.03) However, no changes were seen in, BDI score and ANS score in the post-glycopyrrolate medication group (P < 0.001). Conclusions: Glycopyrrolate is an effective initial method of treating primary hyperhidrosis that, reduces anxiety and improve patients' quality of life.

  • Objectives : This study was conducted for objective verification of effects of spiral taping therapy for the patients with motor disturbance. Methods : To verify whether spiral taping therapy is effective for treating motor disturbance from cervical sprain, 28 patients were randomly allocated into the control and experiment groups. Then 23 subjects who fulfilled the experiment requirements were measured for lateral rotation angle using the goniometer. Changes in rotation were observed and compared. Control group received acupuncture and herbal acupuncture treatment, whileas the experiment group received spiral taping therapy in addition. Results : Differences in age and the degree of motor disturbance were disregarded in comparison of the groups prior to rendering treatments. For the control group, significant changes were observed after the second treatment until the termination of treatment. For the experiment group, significant changes were observed after the first treatment until the termination of treatment. Difference between the groups was insignificant but experiment group with spiral taping therapy showed better results. Conclusion : Spiral taping therapy can be an effective complementary treatment method for treating neck motor disturbance. Further studies in the subject should be conducted to yield more concrete verification.
