A total of 75 subjects were examined using Hahn's color vision test and Hahn's Double 15-Hue test. Among the 75 subjects, 62 subjects detected by screening test among 2700 high school students had defective color vision but good visual acuity and no retinal diseases. The other 13 subjects were detected in out-patient ophthalmic clinic. Results of examination in classifying the types and estimating the extent of color defects were obtained. 1. In the total 75 persons examined, extent of the color defects were as follows; mild ............ 6 cases, moderate.........31 cases, strong...........38 cases. 2. The classification of types of congenital color defects were as follows; Protan .........2 cases, Deutan ........25 cases, Unclassified...48 cases. Lack of advanced study on color discrimination for congenital color deficiency resulted in existing job discrimination against a color defective person by restricting his/her job opportunity. Therefore this kind of research has very important meanings and should be continued.

OBJECTIVE: To investigate employment status after spinal cord injury (SCI) and identify personal, family, and injury characteristics those affect their employment in South Korea. METHODS: Participants were 334 community-dwelling persons 20-64 years of age who had sustained SCI for more than one year. Investigators visited each participant's home to carry out the survey. Bivariate and binary logistic regression analyses were performed to identify personal, family, and injury characteristics that influenced employment after SCI. RESULTS: Employment rate decreased significantly from 82.5% to 27.5% after SCI. Logistic regression showed that the probability of employment was higher in men than women, and in individuals older than 45 years at the time of injury than those aged 31-45 years of age. Moreover, employment was higher in individuals injured for longer than 20 years than those injured for 1-5 years and in individuals with incomplete tetraplegia than those with complete paraplegia. Employment was lower in individuals with SCI caused by industrial accidents than those injured in non-industrial accidents. CONCLUSION: Injury characteristics are the most important predictors of employment in persons with SCI. For persons with lower employment rate, individualized vocational rehabilitation and employment-support systems are required.

PURPOSE: This study aimed to identify the influence of job stress, compassion satisfaction, and resilience on depression of nurses.METHODS: One hundred seventy six nurses working at one tertiary hospital in one metropolitan city were included. The data collection was conducted from September 1st to October 1st, 2018, using a structured, self-reported questionnaire. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression.RESULTS: The M±SD age of 170 subjects was 29.62±5.59. Depression had significant negative correlations with compassion satisfaction (r=−.50, p < .001) and resilience (r=−.56, p < .001), and a positive correlation with job stress (r=.42, p < .001). In the multiple regression analysis, marital status (β=−.15, p=.015), job stress (β=−.00, p < .001) and resilience (β=−5.47, p < .001) had a significant effect on depression. The explanatory power of the subject's marital status, leisure life, job stress, compassion satisfaction, and resilience on depression was 44.1% (F=27.62, p < .001).CONCLUSION: The study results showed that single status, low job stress, high resilience may decrease depression of nurses. Reducing job stress and improving resilience of nurses will virtually contribute to reduce their depression that can influence on not only nurses' health status but also their performance and qualitative caring for patients.

PURPOSE: The purpose of our study was to evaluate the cause of acquired third, fourth, and sixth nerve palsy while also establishing recovery rates and important factors for recovery. METHODS: A retrospective chart review was performed for 92 patients who visited the ophthalmologic department of Konyang University Hospital with acquired third, fourth, and sixth nerve palsy from March 2015 to February 2016. Recovery rates and factors for recovery were evaluated in only 66 patients who received first ocular exam within 2 weeks of onset and who were followed up for at least 6 months. Complete recovery was defined as both complete recovery of the angle of deviation and the restoration of eye movement in all directions. For the degree of ocular motor restriction, −4 was defined as not crossing the midline and −2 was defined as 50% eye movement. The degree of ocular motor restriction was analyzed from −1/2 to 4. RESULTS: The fourth nerve was affected most frequently (n = 37, 40.2%), followed by the sixth cranial nerve (n = 33, 35.9%), the third cranial nerve (n = 18, 19.6%), and a combination of 2 or more cranial nerves (n = 4, 4.3%). Vasculopathy (n = 44, 47.8%) was the most common etiology, followed by trauma (n = 14, 15.2%), idiopathic (n = 13, 14.1%), inflammation(n = 10, 10.9%), neoplasm (n = 9, 9.8%), and aneurysm (n = 2, 2.2%). Complete recovery rate occurred for 66.7% (n = 44) of patients, and the overall recovery rate (i.e., at least partial recovery) was 86.3% (n = 57). Significant factors for complete recovery were the initial deviation angle and the limitation of extraocular movement (p < 0.001, p = 0.005, respectively, according to univariate analysis). CONCLUSIONS: In this study, paralytic strabismus due to vasculopathy was the most common etiology, and a lower degree of initial deviation resulted in an improved complete recovery rate. In addition, a high overall recovery rate was possible through quick diagnosis and early treatment of cranial nerve palsy.

Cortical metastasis usually occurs in the diaphysis of the long bones with the appearance of a cookie-bite pattern; this is associated with cortical destruction extending into the soft tissue as well as into the medullary cavity, or there can be a periosteal reaction. We report here on a 66-year-old woman who was diagnosed with intracortical metastasis in the proximal metaphysis of the right femur as an initial metastatic focus from primary lung cancer. CT detected an intracortical osteolytic lesion without cortical destruction or thickening. The MR images showed extensive peritumoral edema in the surrounding soft tissue and adjacent bone marrow edema, and this all mimicked osteoid osteoma.

PURPOSE: Respiratory syncytial virus(RSV) bronchiolitis is believed to be associated with later development of asthma and wheezing. This study was conducted to determine the relationship between the age of the first RSV bronchiolitis episode, the development of later wheezing and asthma, and the related other factors. METHODS: We studied 255 infants admitted with their first episode of RSV bronchiolitis. Epidemiological and clinical data were collected retrospectively from medical records and through telephone interviews. The patients were divided into < or =3 months, 4 to 12 months, and 13 to 24 months. RESULTS: Eighty-one infants were < or =3 months, 115 were 4 to 12 months, and 59 were 13 to 24 months old. The gender ratios (Male:Female) were 1:1, 1.6:1, and 3.2:1. Familial and personal history of allergic diseases and disease severity did not significantly differ according to the age of the first RSV bronchiolitis episode. The occurrence of wheezing was associated with the presence of a familial and personal history of allergic diseases, but not with gender (male) or disease severity. The risk for asthma increased when the infants had their first RSV bronchiolitis episode at an older age. A personal history of allergic diseases was associated with an increased risk for asthma. CONCLUSION: Asthma was more frequently diagnosed in older infants. The most important risk factors for recurrent wheezing and asthma were a familial and personal history of allergic diseases. Therefore, it was thought that RSV bronchiolitis is not the cause of recurrent wheezing and asthma, but that infants with a genetic predisposition to asthma have an increased risk for RSV bronchiolitis.

Although ultrasonography is the most commonly used first-line imaging modality of the female pelvis because of diagnostic accuracy, low cost and safety, MRI is the best imaging modality of choice for the evaluation of the female pelvis. The indication of female pelvis MRI is diverse and includes the evaluation of Mullerian duct anomaly, differential diagnosis and characterization of uterine and ovarian tumors, and staging of malignant uterine and ovarian tumors. Understanding of MR protocols according to the specific gynecologic pathology allows accurate diagnosis and proper patient management.
