1.Comparison of Human Attributes for School and Hospital Dietitians : by Importance and Frequency Scale.
Korean Journal of Community Nutrition 1998;3(2):281-291
Job analysis was done by the method of interview and survey to find out the human attributes needed for dietitans' job performance. The knowledge, skills, abilities and other characteristics including personality were major items in the questionnaire. The questionnaire was distributed to 340 schools and hospital dietitians. Among these, 201 were compeletely filled out, returned and statistically analyzed according to the frequency scale and importance scale respectively. The results were as follows : 1) The age, education, job experience and monthly pay of hospital dietitians were higher than those of school dietitians. This was partly due to the reflection of short chronicle of school foodservice. 2) The most important human attributes for rwo groups were commonly shown as sincere and faithful personality, good human relationship and responsibility for business outcome. 3) Computer skill and menuplanning ability were human attributes of the most frequently used by school dietitians, whereas knowledge of diet therapy, clinical nutrition, and pathology of disease were frequently used by hospital dietitians. 4) The correlation coefficients between two groups were as follows : Spearman's rho value of personality, skills and abilities, and knowledge were 0.806, -0.432,-0.203 respectively, according to the importance scale. 5) An overall view from t test between two groups, various human attributes, especially knowledge were more frequently used by hospital dietitians.

PURPOSE: This study was performed to describe the ultrastructure of stromal nerve fibers in central, mid-peripheral, and peripheral parts of the human cornea by flat serial corneal section. METHODS: Seven samples from fresh normal cornea, derived from eyes with retinoblastoma and eyes from eye bank, were processed for transmission electron microscopic examinations. Flat serial sections reaching from mid-epithelium to the anterior stroma were observed. RESULTS: The myelinated and unmyelinated nerve fibers are alternately arranged and run parallel to the stromal collagen fibers at the periphery of the cornea. The main difference between the limbal and the central cornea is the presence of myelinated nerve fibers in the anterior peripheral stroma. The diameter of the unmyelinated nerve fiber measures between 0.25 and 0.63 micrometer in size. The corneal nerve fibers contain vesicles, mitochondria, and glycogen particles. The peripheral nerve fibers contain both clear and dense vesicles. The nerve fiber is separated by an interval of 0.3 micrometer from the cytoplasmic wall of keratocyte at the center of the cornea. CONCLUSIONS: The majority of the corneal nerve fibers can be classified as C-fibers due to their size. The presence of both clear and dense vesicles within the cytoplasm of the periphery of the cornea suggest that a small portion in the peripheral corneal nerve may be originated from the sympathetic nervous system. A close vicinity between the nerve fibers and keratocyte supports that nerve fibers might modulate the release of growth factors in the regulation of stromal and epithelial metabolism.

3.Job Analysis of School and Hospital Dietitians : Factor Analysis of Human Attributes.
Korean Journal of Community Nutrition 1999;4(3):431-440
This study was mainly done by factors analyzing to find out the structure and the dimension of the results of a previous study; analyzing the school and hospital dietitians' human attributes needed for successful job performance(Song 1998). The results were as follows: 1) Through factor analysis, the 12 knowledge items were categorized into 4 groups ; 'basic knowledge of food and nutrition', 'knowledge of clinical nutrition and diet therapy', 'knowledge of medial science', and 'knowledge from experience and common sense'. These 4 knowledge factors were more frequently used and importantly recognized by hospital dietians compared with school dietitians. 2) The 38 skill and ability items were categorized into 7 groups ; 'ability of program development and research', 'ability of counseling and nutrition education', 'ability of production control and facility management', 'ability to use computer', 'ability to cooperate with others', 'ability to manage consignment marketing', and 'ability of managing situations and informations'. Different skills and abilities were required for each group. 3) The 11 personality items were categorized as 3 groups ; 'respoinsibility and sincerity', 'positive personality', and 'affirmative and inquisitive personality'.

PURPOSE: The purpose of the study was to investigate the effect of work engagement (WE) on organizational citizenship behaviors (OCB) and ability to control career commitment (CC) in the relationship between work engagement and OCB. METHODS: Data were collected using structured self-report questionnaires from 205 nurses currently working at three national hospitals. Data were analyzed using descriptive statistics, ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis using the SPSS 21.0 program. RESULTS: Mean scores for each variable were: WE 3.77 (on a 7-point scale), OCB 3.41 (on a 5-point scale), and CC 3.05 (on a 5-point scale). As a result, comparison showed that all research variables were higher with age, OCB was higher with total clinical career, and CC was higher with higher education level. Total clinical career, WE and CC had a significant effect on OCB, and CC had a moderate effect on work engagement and OCB. These variables had a total explanatory power of 38% for OCB. CONCLUSION: The nurses' WE had a positive effect on OCB, and the CC showed a moderating effect on the relationship between WE and OCB. Therefore, we suggest that CC is an important factor in improving nurses' OCB.

Henoch-Schonlein purpura is a condition of unknown origin probably related to an autoimmune phenomenon involving an IgA immune complex disorder. Henoch-Schonlein purpura is a rare cause of intramural hematoma of the duodenum. We herein report a case of intramural hematoma of the duodenum and duodenal obstruction associated with Henoch-Schonlein purpura in a 14-yearold boy. On admission, the patient presented with hematemesis due to duodenal ulcer bleeding. Three days later, he developed both forearm and calf purpurae, fever and severe bile juice vomiting. An endoscopy revealed a luminal obstructing erythematous mass with bulging nature at the third portion of the duodenum. Abdominal CT scan and hypotonic duodenography showed intramural hematoma in the third portion of the duodenum and luminal obstruction. Hematoma removal was performed for the correction of intestinal obstruction. Increased awareness of the gastrointestinal manifestations of Henoch-Schonlein purpura should aid in the recognition of this disorder.

PURPOSE: To determine the characteristics of benign breast calcifications on mammogram. MATERIALS AND METHODS: Benign breast calcifications on mammograms of 25 patients, which were confirmed by needle localization and excisional biopsy(15 cases), cytology(1 case), or follow-up study(9 cases), were retrospectively analysed according to size, shape, number, distribution, and density. RESULTS: The size of benign breast calcifications was uniform in 4 cases (16%), and variable in 21 cases (84%). The shape of calcifications was round or oval in 18 cases(72%), linear or branching pattern in 6 cases (24%), and irregular in 1 case(4%). The number of calcifications was 2-5 in 7 cases(28%), and over 6 in 12 cases(48%). The distribution of calcifications was focal in 13 cases(52%) and diffuse in 12 cases(48%). The density of calcification was homogenous in all 25 cases(100%). CONCLUSION: Analysis of number, shape, size, and distribution is helpful for the diagnosis of benign breast calcifications. However the homogenous density of the calcification is suggested to be the most helpful criterion for the diagnosis of benign breast calcifications.

Journal of Korean Academy of Nursing 2016;46(5):619-629
PURPOSE: This study was a systematic review to evaluate the effects of aromatherapy on menopausal symptoms, perceived stress and depression in middle aged-women. METHODS: Eight databases were searched from their inception September 8, 2015. Two reviewers independently performed the selection of the studies, data abstraction and validations. The risk of bias was assessed using Cochrane criteria. For analysis of the data, a meta-analysis of the studies was performed. RESULTS: From the electronic databases, 73 articles were selected, and 19 removed due to duplication. After two reviewers read the abstracts of 54 studies, 34 studies were selected. Complete papers for 34 original articles were read and, 12 studies which met selection criteria were reviewed and the effects of aromatherapy on menopausal symptoms, stress and depression analyzed using meta-analysis with RevMan. In the 2 studies which included Randomized Controlled Trials testing of aromatherapy on menopausal symptoms and comparison of control and placebo groups were done. Aromatherapy massage was favorably effective in reducing the menopausal symptoms compared to the control group (n=118, MD=-6.33; 95% CI -11.51 to -1.15), and compared to the placebo group (n=117, MD=-4.14; 95% CI -7.63 to -0.64). Also aromatherapy was effective in reducing stress (n=72, SMD=-0.64; 95% CI -1.12 to -0.17) and depression (n=158, MD=-5.63; 95% CI -10.04 to -1.22). CONCLUSION: There is limited evidence suggesting that aromatherapy for middle-aged women may be effective in controlling menopausal symptoms, perceived stress and depression.

Journal of Rheumatic Diseases 2011;18(3):168-174
OBJECTIVE: In patients with interstitial lung disease (ILD) associated with connective tissue disease (CTD), chronic ILD related symptoms may often dominate the clinical picture or precede systemic findings and thus often be seen by a non-rheumatologist. The purpose of this study was to evaluate the importance of rheumatologic consultation during ILD work up. METHODS: We retrospectively reviewed 64 patients with ILD from a single tertiary center for their clinical and laboratory characteristics, rheumatologic consultation status, and result of the consultation. American College of Rheumatology criteria for classification of each connective tissue disease were utilized. Undifferentiated connective tissue disease (UCTD) was classified by pre-specified criteria. RESULTS: A total of 23 (36%) of the ILD patients had associated CTD. Five (8%) patients had underlying CTD before the diagnosis of ILD, whereas 18 (28%) patients were diagnosed with CTD after the rheumatologic consultation. ILD patients with CTD were predominantly female, had significantly more frequent radiographic diagnoses of nonspecific interstitial pneumonia, increased frequencies of high titer antinuclear antibody positivity, and rheumatoid factor positivity. Rheumatologic consultation was referred in 36 (56%) patients. In 18 (50%) of the referred patients, CTD was diagnosed. In 61% of the patients diagnosed with CTD as a result of rheumatologic consultation, changes in therapy occurred. CONCLUSION: A substantial proportion of patients with ILD are found to have an underlying CTD upon evaluation by a rheumatologist. Since ILD associated with CTD mimics idiopathic interstitial pneumonia, rheumatologic consultation may have a significant impact on the clinical care of ILD.

For many years, interest in cardiac function has primarily centered around the systolic pump performance of the left ventricle. it is now recognized, however, that diastolic abnormalities may be just as important in the pathophysiology of certain cardiac disease states. To examine the left ventricular abnormalities (especially diastolic events) in hypertension, diastolic and systolic time intervals were measured from simultaneous high-speed recordings of a phonocardiogram, ECGs, apexcardiogram, echocardiogram and external carotid pulse in 35 hypertensive patients and were compared with those in 15 normal subjects. The hypertensive patients showed significantly prolonged preejection period (PEP) and shortened ejection time (ET), compared to those in normal control subjects (p<0.005, p<0.05 respectively). The PEP/ET ratio too was different from the control subjects in hypertensive patients (0.335+/-0.050 vs 0.422+/-0.666; p<0.005). The isovolumic relaxation time (IVRT) was increased to 81.3+/-15.0 msec, which was significantly longer (p<0.005) than in normal subjects (56.7+/-10.7 msec), in patients with hypertension. The active filling period (AFP) was also prolonged. In patients with hypertension there was no significant difference in rapid filling period and slow filling period compared with those in normal subjects. It is likely that in hypertensive patients the alterations of diastolic time intervals, reflecting disorders in elasticity and compliance, may occur in conjunction with abnormal systolic events.

PURPOSE: This study was conducted to identify emotional labor, nursing work environment, self-efficacy and happiness index and address factors associated with happiness index to provide basic resources for national psychiatric hospital nurses' happiness at work. METHODS: Participants were 249 nurses working in 5 national psychiatric hospitals. They participated in the survey and data were collected from May 16 to July 30, 2016. Data were analysed using SPSS/WIN 22.0. RESULTS: Mean scores were nurses' emotional labor, 3.89, nursing work environment, 2.77, self-efficacy, 3.77, and happiness index, 3.52. There were significant differences on the happiness index for: department, type of work, career length, position and payment. Happiness index was influenced by self-efficacy, work environment and emotional labor. Explanatory power of these variables was 36.9%. CONCLUSION: These results show that self-efficacy and work environment are important factors related to the happiness of the national psychiatric hospital nurses. Additionally, developing an effective program to facilitate self-efficacy of nurses and research studies to identify effects of such a program are required.
