Objective: This study was carried out to evaluate the distribution and clinical features of patients with degenerative change of the mandibular condyle. Methods: Six thousand and seventy patients with TMD (temporomandibular cisorder) were selected for this study, who had complete initial clinical records and radiographs. Panorama and TMJ panorama radiographs were used to screen the degenerative change in the condyle, and the patients were divided into DJD (degenerative joint disease) and non-DJD groups. Results: The distribution. and clinical features of the two groups were compared. Out of the total number of patients, 31.7% were in the DJD group, and 68.3% were in the non-DJD group. The portion of females was larger in the DJD group (80.8%) than in the non-DJD group (67.5%), and the DJD group had high prevalence in the second and third decades. Lack of incisal contact, retrusive chin, facial asymmetry, and mouth opening limitation were the chief complaints of the patients who had positive relation to DJD. Conclusion: Patients with an orthodontic treatment history, CO-CR discrepancy and crepitation were at possible risk of having DJD.

In normal auditory systems, the difference between the bone conduction thresholds obtained with the test ear opened and occluded in low frequency signals below 1, 000Hz is about 10~25 dB. But no difference in these thresholds suggests the presence of a lesion in the conductive mechanism. Sullivan added the differences in these thresholds at 250Hz, 500Hz and 1,000Hz and called "Occlusion Index". In oder to study the audiological significance, we have measured the occlusion index in 40 ears of normal persons, 20 ears of chronic otitis media patients and 20 ears of sensori-neural hearing impairment patients. We also measured the static compliance in 40 normal ears and observed the correlation with the occlusion index. The results are as follows: 1. Occlusion index was 33. $10\pm10.63dB$ in normal group, $3.10\pm3.03dB$ in chronic otitis media; group, $28.10\pm15.17dB$ in sensori-neural group. 2. Static compliance in normal group was $0.61\pm0.31cc$ (0.22~1.75cc) 3. Occlusion index showed inverse proportion to static compliance.

Objective : The purpose of this study is to investigate the effect of intensive one-day training on Movement Assessment Battery for Children-2 screening developmental coordination disorder. Methods : We provided intensive one-day training which combined lecture and practice on MABC-2 assessment tools for 33 trainees. Interrater reliability was calculated by using Intraclass correlation coefficient (ICC) with the raw score of results scored simultaneously by experts and trainees of MABC-2. Results : The 33 female trainees with an average of five years and three months of experience and less experience using motor skill assessment tools scored raw score while watching the performance scenes of normal children. The results of the ICC between experts and training participants in MABC-2 obtained a high confidence 0.95 and above (p<.001). Conclusion : Clinicians who participated in one-day training seems to use MABC-2 effectively. Through this, one-day training seems to be effective in acquiring new motor skill assessment tools.

The purpose of this study was to explore the predictors of turnover intention among nurses working in general hospitals. The subjects were 181 nurses who worked in two general hospitals in Gyeonggi-do, Korea. Data were collected from June to November 2018, and analyzed by descriptive statistics, Independent t-test, One-way ANOVA, Pearson's correlation coefficients, and Stepwise multiple regression analysis, using SPSS/WIN 21.0. The main findings of this were as follows. The mean scores for the nursing work environment, professional self-concept, job satisfaction and turnover intention were $2.43{\pm}0.38$, $2.60{\pm}0.25$, $2.59{\pm}0.29$ and $3.43{\pm}0.72$ points. Turnover intention is negatively correlated with the nursing work environment (r=-.43, p<.001) and job satisfaction (r=-.46, p<.001). Factors influencing turnover intention were job satisfaction(${\beta}=-.47$, p<.001), nursing work environment(${\beta}=.32$, p<.001), professional self-concept(${\beta}=.20$, p<.001), and total length of a clinical career(${\beta}=-.15$, p<.05) showing an explanatory power of 38%. Since various variables influence the turnover intention of nurses, it is necessary to improve the nursing environment in the medical field rather than the strategy to increase the number of simple nurses. In the university, education for establishing through introductory nursing specialty is needed.

South Korea has been free from endemic malaria by P. vivax since the mid-1980s, but malaria infections, including military outbreak in 1995, have been increasing steadily in the soldiers serving near the western part of Demilitarized Zone(DMZ) since its first resurgence in 1993. We experinced 8 cases of delayed onset P. vivax malaria in young men who had never been abroad and had no history of blood transfusion or parenteral use of drug. All the patients had served near the western part of DMZ during their military life. They were admitted to Yeungnam University hospital due to cyclic fever with chills and the clinical symptoms were developed 2 months to 11months after discharge from military service. Peripheral blood smears showed typical ring forms and trophozoites of P. vivax in red blood cell. Patients were treated with hydroxychloroquine and primaquine showing rapid clinical and hematologic responses in all cases, but 2 cases were relapsed later. We presumed that theses cases were delayed onset of P. vivax infection resulted from the recent outbreak in the western part of DMZ, in 1995. Therefore, we reported theses cases to emphasize the need of active surveillance and prevention.

The purpose of this study is to identify the differences of student satisfaction depending on tutor's content expertise and experience in PBL of nursing. Nursing department, the subject of this study, is operating Hybrid PBL Curriculum that integrates the courses in nursing for all grades. Tutor's expertise was categorized based on their final dissertations and the clinical fields for which they worked. Tutor's experience in PBL is less than one year for beginners and more than 10 years for experts. After the PBL class for 6 weeks, the 3rd grade students were surveyed. The results showed that there was a statistically significant difference in the student satisfaction according to the content expertise, however, the student satisfaction depending on tutor's experience and the interaction effect between tutor's content expertise and experience were not significant. This study has raised the importance of the role of tutor as content expert in PBL. It is suggested that future studies be repeated for more tutors with diverse subject areas and majors to examine the differences between diverse variables other than student satisfaction.

Restrictive dermopathy is a rare autosomal recessive disorder in which rigidity or tautness of the skin from the second trimester causes a fetal akinesia deformation sequence (FADS) and early death. Characteristic features include taut skin with prominent subcutaneous vessels, widely open fontanelles and cranial sutures, distinctive facies, flexion contractures, pulmonary hypoplasia, sparse eyelashes and and eyebrows, thin dysplastic clavicles. The histologic abnormalities of the skin are located in a thin dermis, consisting of compactly arranged collagen fibers, scanty elastic fiber. The dermoepidermal junction is flat, and epidermal appendages are absent, miniaturized or immature. The presence of adipose tissue may be increased. We report on the first Korean case of restrictive dermopathy with typical clinical features and histological findings.

The purpose of this study was to examine knowledge, attitude, and altruism on blood donation and influential factors in regard to its experience. Data were collected through questionnaires with a convenience sample of 311 healthcare providers. Subjects with blood donation experience accounted for 63.3%. In both nurses and laboratory technologist, the rate of blood donation in male group has higher than that of female group. There were differences in the knowledge of blood donation dependent upon the type of occupation of healthcare providers and the higher age and the longer period of career experience proved to be the significant factor for the level of altruism. The study suggests that more practical, concrete strategies should be identified to participate in blood donation. The further relevant variables need to be investigated since the most determinant motivator for blood donation among healthcare providers was the responsibility to help others.
