PURPOSE: The purpose of this study is to identify factors that affect coping with fatigue in middle-aged men according to Q-methodology and to provide basic strategies for health promotion. METHOD: 25 subjects in Seoul, Incheon, Chung-buk classified 24 selected Q-statements in to 9 points standard. The collected data were analyzed by using a QUNAL pc program. RESULT: Principal component analysis identified 3 types of coping with fatigue among middle-aged Korean men. 1st Type: Coping with fatigue through various kinds of game, using alcohol, smoking cigarette other than rest and sleep. 2nd Type : Coping with fatigue through rest and sleep, taking medicine or food which helps relieving fatigue. 3rd Type : Coping with fatigue through acitivities such as sports or trip other than sleep. CONCLUSION: We have found how Korean middle-aged men cope against fatigue through this research. To setup and apply different nursing intervention on each type based on this result is needed.

We report a case of pneumomediastinum, subcutaneous emphysema, and mild pneumothorax that occurred after endotracheal intubation with a metallic endotracheal tube for the laser operation. Fortunately, pneumomediastinum and subcutaneous emphysema were self-limited. But potentially life-threatening events such as upper airway obstruction, tension pneumothorax, pneumopericardium, mediastinitis might be possible. These complications may result from mucosal perforation of upper airway. The use of a tube with rigid and relatively narrower internal diameter than polyvinylchloride endotracheal tube, tough endotracheal intubation technique, high peak inspiratory pressure, suction technique and negative pressure are included as complication factors.

This study was performed to verify the possibility of MTA and calcium sulfate as a pulp capping agent through comparing the dental pulp response in dogs after capping with MTA, calcium sulfate, and calcium hydroxide. 24 teeth of 2 dogs, 8 month old, were used in this study. Under general anesthesia, cervical cavities were prepared and pulp was exposed with sterilized #2 round bur in a high speed handpiece. MTA, calcium hydroxide, and calcium sulfate were applied on the exposed pulp. Then the coronal openings were sealed with IRM and light-cured composite. Two months after treatment, the animals were sacrificed. The extracted teeth were fixed in 10% neutral-buffered formalin solution and were decalcified in formic acid-sodium citrate. They were prepared for histological examination in the usual manner. The sections were stained with haematoxylin and eosin. In MTA group, a hard tissue bridges formation and newly formed odontoblasts layer was observed. There was no sign of pulp inflammatory reaction in pulp tissue. In calcium hydroxide group, there was no odontoblast layer below the dentin bridge. In pulpal tissue, chronic inflammatory reaction with variable intensity and extension occurred in all samples. In calcium sulfate group, newly formed odontoblast layer was observed below the bridge. Mild chronic inflammation with a few neutrophil infiltrations was observed on pulp tissue. These results suggest that MTA is more biocompatible on pulp tissue than calcium hydroxide or calcium sulfate.

Behcet disease (BD) is rare in childhood. We report a 9-year-old boy with neuro-Behcet disease who presented diplopia and weakness on the left side after a cerebral concussion. Brain magnetic resonance imaging (MRI) revealed hyperintensity of the right mesodiencephalic junction on T2-weighted and fluid attenuated inversion recovery images. Prednisolone administration resulted in complete remission and normalization of abnormal MRI finding. Brain MRI is a useful diagnostic tool when the neurological sign is the first symptom of subclinical BD.

PURPOSE: We developed an objective structured oral examination (OSOE) case to assess the medical ethics of students. The aim of this study was to assess the reliability of OSOE with generalizability theory. METHODS: One 10-minute OSOE that contained key questions was developed. The evaluation sheet consisted of 4 domains: moral sensitivity, moral reasoning, decision making, and attitude. The total number of items was 13. The numbers of checklist items and global rating items were 11 and 2, respectively. Items and key questions were validated by 6 professionals. Standardization of the raters and the pilot study was performed before the OSOE. Fifty-four third-year medical students participated in the OSOE. The OSOE was duplicated, and 2 professors assessed 1 student independently. Each station lasted 8 minutes and was followed by a 2-minute interval,during which raters completed the checklist forms. We analyzed the reliability of the OSOE with the GENOVA program. RESULTS: The reliability (generalizability coefficient) was 0.945, and the interrater agreement was 0.867. The type of item, checklist or global rating, was the largest variance component. The reliability of the checklist alone was 0.668 and that of the global rating alone was 0.363. CONCLUSION: The OSOE is reliable and can be used to assess ethics. More research should focus on achieving validity.

Background:
Research is continuously being conducted on the relationship between the airway and malocclusion. The nose, asthe upper part of the respiratory pathway, plays a critical role. While various international studies employ the Nasal Index classification for nasal morphology, domestic research remains scarce. This research investigates the proportions of nasal morphology in malocclusion patients utilizing a 3D software.
Methods:
The study evaluated 100 malocclusion patients in their 20s (40 Class I, 34 Class II, 26 Class III). Cone-beam computedtomography was used with the Mimics (ver. 22; Materialise) 3D program to model the skull and soft tissues of the patients in three views: coronal, sagittal, and frontal.
Results:
The results showed that in Class I, there were 5 leptorrhine (long and narrow) cases, 30 mesorrhine (moderate shape)cases, and 5 platyrrhine (broad and short) cases. In Class II, there were 3 leptorrhine, 25 mesorrhine, and 6 platyrrhine cases.In Class III, there were 2 leptorrhine, 21 mesorrhine, and 3 platyrrhine cases.
Conclusion
The findings of this study indicate that there is no significant correlation between the size of the nose and malocclusionin patients. Additionally, additional research related to this study is expected to be necessary.

This study was performed to assess the radiopacity of a variety of root canal sealers according to the specification concerning root canal sealers. Ten materials including Tubli-Seal(TM), Kerr Pulp Canal Sealer(TM), AH 26(R), AH plus(R), AH plus jet(TM), Ad sea l(TM), Sealapex(TM), NOGENOL(TM), ZOB seal(TM), Epiphany(TM) and dentin were evaluated in this study. In the first part, densitometric reading of an each step of aluminum step wedge on occlusal film was performed at different voltage and exposure time. In the second part, ten specimens were radiographed simultaneously with an aluminum step wedges on the occlusal films under decided condition. The mean radiographic den sity values of the materials were transformed into radiopacity expressed equivalent thickness of aluminum (mm Al). The following results were obtained. 1. Among the various conditions, the appropriate voltage and exposure time that meet the requirement density was 60 kVp at 0.2 s. 2. All of the materials had greater radiopacity than 3 mm Al requirement of ANSI/ADA specification No. 57 (2000) and ISO No. 6876 (2001) standards. 3. The radiopacity of materials increased as thickness of materials increased. 4. The mm Al value of each specimen at 1mm in thickness has a significant difference in the statistics. It suggests that root canal sealers have a sufficient radiopacity that meet the requirement.
