We describe the case of a 79-year-old man who presented with progressive aggravation of severe axial neck pain and fever 3 days after transurethral resection of the prostate (TURP), despite maintaining neutral neck posture during surgery. Laboratory examination revealed markedly elevated C-reactive protein levels and erythrocyte sedimentation rates. Computed tomography revealed crown-like calcifications surrounding the odontoid process. We diagnosed crowned dens syndrome (CDS) as the cause of acute-onset neck pain after TURP. The patient was treated with nonsteroidal anti-inflammatory drugs for 5 days, and his symptoms resolved completely. CDS is a rare disease characterized by calcific deposits around the odontoid process with acute onset of severe neck pain and restricted motion. Evidence of inflammation on serological testing and fever are typical of CDS. However, the prevalence and pathophysiology of CDS remain unclear. We hypothesized that systemic inflammation after prostate surgery may have induced a local inflammatory response involving calcification around the odontoid process.

The purpose of this study is to think about the educational effect of school space innovation project through user participation, to investigate and analyze the actual situation of user participation school space innovation project of elementary, middle and high schools of Incheon Metropolitan Office of Education, The educational effect was analyzed. After the students and teachers participated in the improvement of the school space, the students' skills were improved. Overall, emotional abilities were most cultivated, and elementary school students were most physically cultivated. The intimacy created by participation and activities and play-oriented projects may have helped to develop students' abilities. In addition, the school became fun after user participation, and there was a positive effect of increasing a sense of apathy and belonging. The expansion of user participation has resulted in not only the satisfaction of space but also the friendship and emotional part of students. As a result of this study, the school space constructed through the user participation process brought about significant educational changes in school life and individual quality of life in the learning activities and school life of teachers and students, the main users of the school space.

This thesis attempts to provide a foundation for effective preventative education of middle school students regarding school violence after identifying the level of perception of school violence as well as analyzing perception of preventive education among students. The study compiled data on 474 middle school students from middle schools in Jeollanamdo. The findings of the study are as follows. First, most of the students were aware of the necessity for preventive education regarding school violence. By gender, girls and those of lower grades showed great class participation and satisfaction. Second, research on the preventive education found differences in the seriousness of school violence according to school location. Fourth, preventive education conducted once or twice a month was the most desirable condition for middle school students. As a result, schools should consider gender differences and grade level when, developing an education program in order to prevent school violence.

Purpose: Nasal bone fractures are often classified as minor injury. However, the incidence of posttraumatic nasal deformity remains alarmingly high. It is because of unnoticed septal fracture. This study was conducted to determine the necessity of septoplasty for patients with nasal bone fracture accompanying grade I septal fractures. Methods: Among 105 patients with nasal bone fractures, 52 who had grade I septal fracture were diagnosed based on physical examination and computed tomography. Patients' age ranged from 14 to 65 years (mean 29.25 years), and 35 were male and 17 female. Patients were divided into 2 groups according to surgical treatment methods: patients who underwent closed reduction only (group 1, n=28) and those who underwent simultaneous closed reduction and septoplasty (group 2, n=24). The treatment outcomes were evaluated by comparing changes in nasal airway volume measured by acoustic rhinometry before the surgery, 3 months and 6 months after the surgery according to the timing of surgical repair and surgical treatment methods. Results: Nasal airway volume increased after the surgery by 17.8% in 3 months after the surgery, 25.2% in 6 months in group 1 and by 22.7% in 3 months, 35.8% in 6 months in group 2. The increase in airway volume after the surgery by 26.3% in 3 months after the surgery, 34.2% in 6 months after the surgery in operation within 1 week after trauma and by 12.1% in 3 months, 22.2% in 6 months after the operation later 1 week after trauma. The difference was statistically significant. Three patients in group 1 complained of intermittent nasal obstruction, two of whom showed a decrease in nasal airway volume by acoustic rhinometry. Conclusion: Most patients with nasal bone fractures accompanying grade I septal fractures have been treated with closed reduction in clinical settings. However, the results of this study suggest that septoplasty be performed after a correct diagnosis of septal fracture is made through comprehensive physical examination and computed tomography. Septoplasty is important to obtain more favorable outcomes and reduce complication.

Several chemotherapeutic agents are known to develop pulmonary toxicities in cancer patients, although the frequency of incidence varies. Cyclophosphamide is a commonly encountered agent that is toxic to the lung. Additionally, granulocyte colony-stimulating factor (G-CSF) being used for the recovery from neutropenia can exacerbate lung injury. However, most of the patients reported previously that the drug-induced interstitial pneumonitis were developed after three to four cycles of chemotherapy. Hereby, we report a case of peripheral T cell lymphoma which rapidly developed a fatal interstitial pneumonitis after the first cycle of combined chemotherapy with cyclophosphamide, adriamycin, vincristine, prednisolone, and etoposide and the patient had also treated with G-CSF during neutropenic period.

Background Orthognathic surgery is required in 25% to 35% of patients with a cleft lip and palate, for whom functional recovery and aesthetic improvement after surgery are important. The aim of this study was to examine maxillary and mandibular changes, along with concomitant soft tissue changes, in cleft patients who underwent LeFort I osteotomy and sagittal split ramus osteotomy (two-jaw surgery). Methods Twenty-eight cleft patients who underwent two-jaw surgery between August 2008 and November 2013 were included. Cephalometric analysis was conducted before and after surgery. Preoperative and postoperative measurements of the bone and soft tissue were compared. Results The mean horizontal advancement of the maxilla (point A) was 6.12 mm, while that of the mandible (point B) was -5.19 mm. The mean point A-nasion-point B angle was $-4.1^{\circ}$ before surgery, and increased to $2.5^{\circ}$ after surgery. The mean nasolabial angle was $72.7^{\circ}$ before surgery, and increased to $88.7^{\circ}$ after surgery. The mean minimal distance between Rickett's E-line and the upper lip was 6.52 mm before surgery and 1.81 mm after surgery. The ratio of soft tissue change to bone change was 0.55 between point A and point A' and 0.93 between point B and point B'. Conclusions Patients with cleft lip and palate who underwent two-jaw surgery showed optimal soft tissue changes. The position of the soft tissue (point A') was shifted by a distance equal to 55% of the change in the maxillary bone. Therefore, bone surgery without soft tissue correction can achieve good aesthetic results.

Purpose: This study is based on an experimental research program designed to evaluate the before and after states of a control group that undertook a series of smoking prevention education sessions. Methods: The research was undertaken between June 2 and July 22, 2008. Students from two public elementary schools in Uiwang City took part in the study. 76 students from one of the schools (School 'W') were designated as the experimental group and 89 students from the other school (School 'O') were allotted to the control group. During the research period, the experimental group held 10, 40 minute discussions on the subject of smoking prevention. The control group had no such sessions and no information was given. The data was collected in 3 stages, firstly after initial study preparation, secondly after five sessions and thirdly after ten sessions. The data was analysed using the SPSS/WIN 12.0 program. Results: First, there was a presumption that the experiment group would have a greater knowledge about the effects of smoking than the control group. This was supported by the data analysis results (F=41.79, p =.000). Second it was presumed that the experiment group would have a more informed attitude to smoking than the control group. This was supported by the data analysis results (F=6.917, p =.009). Third, there was the presumption that the experiment group would have a greater knowledge of the effects of smoking after ten sessions than they would five sessions. This was supported by the data analysis results (F=56.911, p =.000, Scheffe=3rd> 2nd>1st). Fourth, the presumption held that the experimental group would have a more informed attitude to the effects of smoking after ten sessions than they did five. This was supported by the data analysis results (F=14.607, p =000, Scheffe=3rd>2nd>1st). Conclusion: The results appear to show that the elementary school students who participated in the smoking prevention sessions had an increased knowledge of the risks and had also formed a more negative attitude towards smoking. On the basis of the findings of this study, I would suggest that there are benefits in developing learner-centered smoking prevention programs and other related media. Also, smoking prevention discussions should be included in the regular curricula relating to health education.

This study confirmed the life career branching points, and studied qualitatively the career strategy and career identity at that time. The participants in this study were three students from third graders of middle school, three ones from third graders of high school, and three before and after college graduation, which correspond to the vertical transition stage of school education. Three participants were selected before and after 30 years of age, three before and after 40 years of age, and three before and after 60 years of age. Subject analysis of the contents of the 18 interviews, showed that the life career branching point appeared in middle school grade 3, high school grade 3, until employment after graduation, within 3 years after entering their first job, early 40 years, 60 years old, and 80 years old. Second, external situations were due to the influence of important others, or external stimuli, environment, and career events. Third, negative emotions were repeated for each life career branching point. Fourth, as a result of the interview, the career identity confusion was repeated in every life career branching point. Fifth, the career strategy at the life career branching point was categorized as an approach strategy and avoidance strategy.
