The purpose of the study was to investigate the influences of contract foodservice managers' personal characteristics, foodservice characteristics and organizational characteristics on job satisfaction, including interpersonal relationships, self-actualization and promotion opportunity categories. A survey was administered to four hundred contract foodservice managers of five large companies and five small/medium companies in the Seoul and Kyungin areas. The final response rate was 66% (N = 265), and the data were analyzed using SPSS Windows (ver. 12.0). The respondents were 76.1% female, average age 28.8 years, and 73.0% were regular workers. Contract foodservices have profit and loss contracts (69.1%), single menu types (59.6%) and buffet serving styles (37.7%). There are significant differences of job satisfaction by some personal characteristic variables (gender, martial status, age, education, position, work hours, period of working for the present company, and payroll per year) and foodservice characteristic variables (type of contract and charge of food costs). In three job satisfaction categories, foodservice managers reported the highest interpersonal relationship satisfaction, following self-actualization satisfaction and promotion opportunity satisfaction in both large companies and small/medium companies. However, foodservice managers of large companies tended to be more satisfied regarding their promotion opportunities than foodservice managers of small/medium companies (P < 0.05). Work hours, number of meals served/day, male, workload, communication with the clients, relationship with co-workers, obvious role and autonomy were significant factors to increase the job satisfaction in contract foodservices of large companies. On the other hand, relationships with co-workers and males were significant factors to increase the job satisfaction in contract foodservices of small/medium companies. This research suggests that contract foodservice companies need to understand the characteristics of their managers, foodservices and organizations to enhance the job satisfaction of foodservice managers and to develop specified human resource management strategies that can be applied to each company scale.

PURPOSE: The purpose of this study was to determine factors affecting the burden on employment of occupational health care providers as well as to develop strategies to reduce burden on employment of them in the middle size manufacturing enterprises. METHODS: The target population of this study was 123 managers working in the middle size manufacturing enterprises. The study questionnaires were selected, as theories and literature suggested, for explaining employment burden, general characteristics of participants and occupational health providers, general characteristics of companies, evaluation of occupational health provider's role and burden score. RESULTS: The mean of employment burden score of manager was 2.2. There was a significant difference in the employment burden scores, manager's age and education, and occupational health provider's age, type of work, certification, and employment status. Also there was a negative relationship between employment burden scores and occupational health provider's role scores (need, role, satisfaction, and benefit). In the results of the standard multiple regression analysis, manager's need scores on occupational health providers were significant predictors of the employment burden scores. CONCLUSION: It is necessary to change the manager's perception to promote employment of occupational health providers.

BACKGROUND: An inflammatory mechanism has been suggested to contribute to the progression of diabetic nephropathy. Although retinoid, a known anti-inflammatory agent, has been reported to be beneficial in some experimental renal diseases, it has not been shown whether it prevents disease progression in diabetic nephropathy. Therefore, we investigated whether all-trans retinoic acid inhibits inflammatory changes and improves renal function during the early stages of diabetic nephropathy in streptozotocin-induced diabetic rats. METHODS: We evaluated anti-inflammatory effect of retinoid on streptozotocin-induced diabetic nephropathy. Anti-inflammatory effect was determined by the expression of monocyte chemoattractant peptide-1 (MCP-1). RESULTS: Urinary protein excretion was significantly higher in diabetic rats at four weeks after the induction of diabetes mellitus compared with controls, and proteinuria in the group with retinoic acid treatment was decreased (1.25+/-0.69 vs. 0.78+/-0.72 mg/mg Cr, p=0.056). Urinary excretion of MCP-1 was rapidly increased at two days after induction of diabetes mellitus in diabetic rats, and further increased until four weeks of age compared with control rats. Retinoic acid treatment suppressed to 30% reduction of the urinary level of MCP-1 compared with vehicle treated diabetic rats (119.3+/-74.2 vs. 78.1+/-62.7 pg/mg Cr, p=0.078). Immunohistochemistry revealed a significant increase in staining for MCP-1 protein in the diabetic kidney, and retinoic acid treatment significantly suppressed intrarenal MCP-1 protein synthesis. CONCLUSION: Retinoic acid suppressed proteinuria and inflammatory changes in diabetic rats. These results suggest that retinoic acid may have an anti- inflammatory effect in diabetic nephropathy.

We evaluated the correlations between BMI, fasting glucose, insulin, testosterone level, insulin resistance, and prostate size in non-diabetic benign prostatic hyperplasia (BPH) patients with normal testosterone levels. Data from 212 non-diabetic BPH patients with normal testosterone levels, who underwent transurethral resection of the prostate (TURP) due to medical treatment failure, were evaluated retrospectively. Patients with prostate specific antigen (PSA) levels of > or = 3 ng/mL underwent multicore transrectal prostate biopsy before TURP to rule out prostate cancer. Patients with diabetes mellitus (DM) or serum testosterone levels of < 3.50 ng/mL were excluded from analysis. Correlations between clinical and laboratory parameters were determined. Prostate size correlated positively with age (r = 0.227, P < 0.001), PSA (r = 0.510, P < 0.001), and fasting glucose level (r = 0.186, P = 0.007), but not with BMI, testosterone, insulin level, or insulin resistance (each P > 0.05). Testosterone level inversely correlated with BMI (r = -0.327, P < 0.001), insulin level (r = -0.207, P = 0.003), and insulin resistance (r = -0.221, P = 0.001), but not with age, prostate size, PSA, or fasting glucose level (each P > 0.05). Upon multiple adjusted linear regression analysis, prostate size correlated with elevated PSA (P < 0.001) and increased fasting glucose levels (P = 0.023). In non-DM BPH patients with normal testosterone levels, fasting glucose level is an independent risk factor for prostate hyperplasia.

Telomerase is a ribonucleoprotein enzyme that synthesizes telomeric DNA onto the ends of chromosomes. thereby preventing the replication-dependent shortening of these ends. Telomerase activity is detected in a wide range of cancers of various tissues, and its expression may be a critical step in tumor progression. Our objective was to determine if detection of telomerase activity may be an indicator for diagnosis of breast cancer and any association between telomerase activity and prognostic factors of breast cancer. Using a polymerase chain reaction-based telomerase activity assay, we examined telomerase activity in 30 breast cancer specimens (2 ductal carcinoma in situ, 28 invasive ductal carcinoma), 25 benign lesions (14 fibroadenomas, 11 fibrocystic diseases) and 24 normal breast tissues (13 adjacent to malignancy, 11 adjacent to benign lesion). Among surgically resected samples, telomerase activity was detected in 23 (77%) of 30 breast cancers. While telomerase activity was not detected in any of 11 specimens of fibrocystic disease and 11 adjacent normal tissues to benign lesion, surprisingly low levels of telomerase activity were detected in 5 (36%) of 14 fiboadenomas and 1 (7%) of 13 adjacent normal tissues to malignancy. There was no significant difference in expression of telomerase among prognostic factors of breast cancer. In summary, telomerase activity in breast cancer may be useful in diagnosis of breast cancer. We found no correlation between telomerase activity and stage, tumor size or LN status. Mechanisms of telomerase expression are still under investigation; therefore, the significance of telomerase expression in malignant tumors and their progression remains to be determined.

Vasoplegic syndrome occurs in 8~10% of patients following cardiac surgery, and this happens in part because of inducing the inflammatory response. Nitric oxide and guanylate cyclase play an important role in this response, and this is associated with increased morbidity and mortality. For our case, we administered methylene blue (MB), an inhibitor of guanylate cyclase, early after performing cardiopulmonary bypass in a patient with vasoplegic syndrome. The patient recovered immediately after MB administration and maintained an optimal blood pressure without the aid help of any vasopressors.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) may cause changes in the shape of the thoracic cage by increasing lung volume and hyperinflation. This study investigated changes in thoracic cage dimensions and related factors in patients with COPD. METHODS: We enrolled 85 patients with COPD (76 males, 9 females; mean age, 70.6±7.1 years) and 30 normal controls. Thoracic cage dimensions were measured using chest computed tomography at levels 3, 6, and 9 of the thoracic spine. We measured the maximal transverse diameter, mid-sagittal anteroposterior (AP) diameter, and maximal AP diameter of the right and left hemithorax. RESULTS: The average AP diameter was significantly greater in patients with COPD compared with normal controls (13.1±2.8 cm vs. 12.2±1.13 cm, respectively; p=0.001). The ratio of AP/transverse diameter of the thoracic cage was also significantly greater in patients with COPD compared with normal controls (0.66±0.061 vs. 0.61±0.86; p=0.002). In COPD patients, the AP diameter of the thoracic cage was positively correlated with body mass index (BMI) and 6-minute walk test distance (r=0.395, p<0.001 and r=0.238, p=0.028) and negatively correlated with increasing age (r=−0.231, p=0.034). Multiple regression analysis revealed independent correlation only between BMI and increased ratio of AP/transverse diameter of the thoracic cage (p<0.001). CONCLUSION: Patients with COPD exhibited an increased AP diameter of the thoracic cage compared with normal controls. BMI was associated with increased AP diameter in these patients.

OBJECT: The purpose of this study was to establish the normal values of sternocleidomastoid (SCM) tendon reflex in normal Korean adults. METHOD: The study for SCM tendon reflex was performed in 41 normal adults using electric reflex hammer. The compound muscle action potentials (CMAP) of SCM muscle were obtained by SCM tendon tapping. From 5 repeated trials of each subject, the shortest latency and the largest peak-to-peak amplitude of CMAP were chosen for the representative value. RESULTS: Mean values of latency and amplitude were 2.19+/-0.27 msec and 0.70+/-0.38 mV for SCM tendon reflex. There was no significant difference in the latency and amplitude regardless of side or sex (p>0.05). The age and height showed no signifiant correlation with latency and amplitude of SCM tendon reflex (p>0.05). CONCLUSION: We believe that our results can be used as an evaluation method of upper cervical spinal cord.

Cavernous hemangiomas occur throughout the central nervous system. Although they are most commonly found in the brain, the intraspinal lesion accounts for approximately 5% of all adult intramedullary lesions. Widespread use of MR imaging have led to an increase in the reported cases of intramedullary cavernous hamangiomas. Spinal intramedullary cavernomas are positioned in a particularly precarious location, and are more likely to cause clinically significant findings than cranial cavernomas. It is important to recognize cavernomas as a surgically manageable cause of myelopathy. Generally, surgery cannot cure the chronic myelopathy from cavernoma but can halt it's progression. These facts emphasize the need for early diagnosis. In our two cases, they developed initially low back pain and sensory changes of both legs and subsequently paraplegia. We report two cases of intramedullary cavernous hemangioma with the review of literatures.
