OBJECTIVES: To investigate the effects of recognition on the restructuring of the psychosocial well-being of the workers. METHODS: 302 employees were recruited by a stratified random sampling method, from a company located in Seoul, which undergoing an administrative evaluation, in 2001. Subjects were asked to fill out questionnaire sheet on their recognition of the restructuring, and were questions on their psychosocial well-being. A one-way ANOVA and a multiple regression analysis were used to analyze the data. RESULTS: For the psychological well-being, the levels of social performance and self-confidence were significantly different relation to age, educational attainment, marital status, insecurity recogni-tion, and competency recognition. According to the result of the multiple regression analysis, the insecurity recognition was found to significantly affect the social performance and self-confidence, depression, sleep disturbance and anx-iety, general well-being and vitality, whereas the competency recognition affected the social perfor-mance and self-confidence, sleep disturbance and anxiety, and overall psychosocial well-being. CONCLUSION: The insecurity and competency recognitions against the restructuring were found to be the major factors affecting the workers psychosocial well-being. It is suggested that a decreased worker's insecurity recognition of the restructuring, and the competency recognition for the workers psychosocial health needs require promoting.

Renal angiography is a highly valuable diagnostic procedure for the detection and exact evaluation of various renal disease, especially differentiation of benign and malignant lesions. During the period of January 1978 to December 1983, 39patients who had been taken renal angiography were analysed and following results were obtained. 1. Male to female ratio of performing renal angiography was approximately 1:1 and peak incidence was fifth decade. 2. Indication of renal angiography was renal mass, abnormal I.V.P. and R.G.P., renal bleeding, kidney donor, hypertension, in order of its frequency. 3. The most frequent diagnosis encountered was renal cell carcinoma (15 cases), diagnostic accuracy of renal angiography was 93.3%. 4. Arterial embolization of renal cell carcinoma was tried in 2 cases preoperatively, and it was found that this was a valuable method in reducing blood loss, in performing operation.

Background: Blepharitis, a chronic inflammatory condition of the eyelid margin, can cause significant discomfort and impair the quality of life. While traditional treatments like eyelid hygiene and medications are often insufficient, non-invasive therapies such as micro-vibration devices are gaining popularity despite minimal empirical validation. This study evaluated the efficacy and safety of a commercially available microvibration device in a rat model of blepharitis. Methods: Blepharitis was induced in rats using complete Freund’s adjuvant injections. The treatment groups included micro-vibration (180 Hz), micro-vibration with thermal enhancement, and pharmacological interventions with cyclosporine or hyaluronic acid. Ocular signs, including tear break-up time (TBUT), fluorescein staining, eyelid swelling, and telangiectasia, were assessed weekly. Immunohistochemical analysis quantified inflammatory cytokines (interleukin [IL]-1β, IL-6, and tumor necrosis factor-α) in ocular tissues. Results: The micro-vibration therapy significantly improved TBUT, reduced eyelid swelling, and lowered inflammatory cytokine levels. Combining thermal therapy with micro-vibration yielded enhanced antiinflammatory effects, though uncontrolled heating caused tissue damage. Pharmacological treatments were effective but less comprehensive compared to micro-vibration therapies. Conclusion Micro-vibration therapy at 180 Hz demonstrated substantial efficacy in alleviating symptoms of blepharitis and reducing inflammation. However, the uncontrolled thermal function of the device posed safety concerns, emphasizing the need for stringent regulation and parameter control in commercially available devices. This study highlights the potential of micro-vibration therapy as a non-invasive treatment for blepharitis while underscoring the importance of device safety.

Dissociated vrtical deviation(DVD) is frequently associated with infantile esotropia. It is hard to find DVD before surgery for esodeviation, and usually found after surgery. We studied the occurrence of DVD in 176 patients who had had horizontal rectus muscle surgery for the correction of infantile esotropia and followed up for 6 months or more. DVD was seen in 78 patients(44.3%), preoperatively in 27 patients(34.6%) and postoperatively in 51 patients(65.4%). Among 51 patients with DVD after surgery, DVD occurred in 24.0% of patients with preoperative angle of esodeviation less than 50 PD and in 44.6% of patients with preoperative angle of esodeviation more than 51 PD(P<0.01). Most of them(25 of 51 patients) developed DVD within 6 months after esodeviation surgery, however, 12 patients were noted to develop even after 2 years. This shows that we need long term follow-up for the detection of DVD. The occurrence of DVD was not influenced by the time of surgery for esodeviation(P>0.05). Inferior oblique overaction(IOOA) was accompanied with DVD in 71.8% and occurred without DVD in 28.6%. This study revealed postoperative DVD developed more in large angle esotropia such as deviation angle greater than 51 PD, and IOOA was frequently accompanied. The result suggests that in large angle infantile esotropia with mild IOOA and DVD or fundus extorsion we may need the preventive correction of DVD and IOOA.

We investigated the expression of the growth-related nuclear proto-oncogenes, c-fos and c-myc, in early preneoplastic regions and tumor nodules of 3'-MeDAB induced rat hepatocarcinoma. To amplify the levels of these transcripts, we gave cycloheximide (100 mg/kg B.W. i.p.) to each group of rats. The elevated levels of the 2.2 kb c-fos and 2.4 kb c-myc transcripts appeared as early as the 2nd week after feeding on the 3'-MeDAB diet and lasted through the 4th; 6th weeks and tumor. Southern blot analysis indicated that gross amplification or rearrangements were not observed in DNA of the preneoplastic livers and hepatoma nodules. We also measured the rate of the incorporation of [3H] thymidine into hepatic DNA in order to monitor the rate of cell proliferation occurring at the early preneoplastic periods. We have found that the rate of [3H] thymidine incorporation corresponds to the elevated levels of c-fos and c-myc transcripts in the precancerous stages. This finding suggests that the elevated expressions of c-fos and c-myc may result from the continuous cell proliferative stimuli generated in the carcinogen altered cells, which is essential to the initiation and promotion of chemical hepatocarcinogenesis.
