Adzuki bean is sensitive to waterlogging stress. The overall study on the waterlogging stress is limited comparing to the study on the drought and any environmental stress. Therefore, the present study was conducted to investigate the changes in growth characteristics and the expression patterns of proteins at the 5-leaf stage periods of adzuki bean. The domestic cultivar, Arari (Miryang No. 8) was used to test the waterlogging stress. In the waterlogging treatment for 3 days, the plant height showed slightly decrease in the treatment at 3 days of waterlogging, but root fresh weight showed significantly changes at 3 days of the waterlogging treatment. Chlorophyll contents showed also significantly different at 3 days of waterlogging treatment compared to control the plants. The waterlogging stress gradually influenced the growth differences between the control and the treatment respectively. More than 350 pro- tein spots were identified on 2-D gels using an image analysis. Moreover, a total of 28 proteins were analyzed using LTQ-FT-ICR MS. Among these 28 proteins, a total of 18 proteins were up-regulated, and 10 proteins were down-regulated under waterlogging treatment. According to biological process, the most of the proteins were found to be involved in carbohydrate metabolism. Regarding the subcellular local- ization, most of the proteins were localized into chloroplasts in 5-leaf stage.

A new configuration for white light interferometric sensor is implemented. This sensor employs a fiber Michelson interferometer(MI) for path-matching and an Fabry-Perot (FP) interferometer for sensing physical parameters. The interference condition can be met by varying the OPD of MI using PZT actuators. With an FP interferometer of 0.85㎝ cavity length and a 1550㎚ ASE source, the resolution of the system was measured to be 0.017℃/scale. A proposed algorithm is used to locate the position of the central fringe with 49.8㎚/√Hz random walk.

To evaluate the prevalence of cumulative trauma disorders in relation to ergonomic evaluation of their work, 260 female directory assistance operators employed in three branch facilities of the nation-wide telecommunication company. Ergonomic evaluation of the work status was done by two industrial hygienists through inspection. Workers were surveyed with standardized self-administered questionnaire and examined by family physicians and an orthopaedician for cumulative trauma disorders. Laboratory examination of serum aspartate aminotransferase(AST), creatinine phosphokinase(CPK), aldolase and rheumatoid factor was done and X-ray of cervical spine and both shoulders was taken from all subjects and nerve conduction velocity test was done on 57 subjects with suspected nerve entrapment cases. Cumulative trauma disorders were categorized into 3 category according to work-relatedness of the disorders. On ergonomic evaluation of the working posture and work environment, improvement of work posture revealed inappropriate postures and devices. Mean age of the subjects were 39 years old and more than 80% graduated high school or above. Ninety-eight percent of the workers employed in the company for more than 15 years and 74.6% of the workers worked at the VDT job for more than 4 years. Mean daily work hours was 8.0 hours per day and mean break hours was 90.5 minutes per day with mean extra work hours of 10.7 hours per month. Mean daily calls were 1128.6 calls in maximum and 864-8 calls in minimum. On laboratory examination, 13.(5.0%) workers had abnormal AST, 53(20.4%) had abnormal CPK, and 1(0.4%) had abnormal aldolase level. On x-ray examination of cervical spine, 111(42.7%) had loss of or reversed normal cervical lordosis, 10(3.8%) had narrowing of intervertebral space. Nerve conduction velocity test was abnormal in 11(19.2%) among 57 workers. Among disorders categorized as work-related, 131(50.4%) were diagnosed to have fatigue myalgia of levator scapulae, 108(41.5%) had cervical strain or sprain, 47(18.1%) had fatigue arthralgia of phalangeal joints, and 47(18.1%) had probable carpal tunnel syndrome, in 10(3.8%) of those diagnosis was confirmed electrophysiologically. Age, seniority, work duration at present job, workload nor location of facilities were associated with the prevalence of symptoms nor specific diagnoses on simple statistical analysis and multiple logistic regression, which seems to be due to highly selected and homogeneous characteristics of the study subjects. Above results shows that cumulative trauma disorders are very prevalent among directory assistance operators and elaborate effort is needed to reduce the cumulative trauma disorders among the operators.

Authors report a first Korean case of polyneuropathy in an acrylamide producing factory together with an environmental and epidemiologic survey for the ten workers of the same workplace and 46 workers in the production and manufacturing acrylamide in Ulsan, Korea. The case is 30 years old man who worked in the production of the acrylamide for two years. In August, 1997, he had a weakness of the lower extremity with loss of body weight of 15 Kg which progressed to paresthesia of the limbs, the loss of vibration sense, difficulty in walking, speech disturbance, dysuria, constipation, difficulty in erection and swallowing difficulty. Neurologic examination showed a complete loss of vibration and position sense, and loss of deep tendon reflex in all the limbs. There was a contact dermatitis-like skin lesion on the feet. Electrodiagnostic test showed a generalized polyneuropathy of moderate degree involving motor and sensory component of peripheral and cranial nerves. After 8 months' cessation from exposure and supportive care, his symptoms were completely resolved, but abnormality in electrodiagnostic test and vibrotactile perception threshold still persisted, although much improved than before. There were 11 workers in the same workplace of the case, producing acrylamide by microorganism as a catalyst. Environmental monitoring of the workplace revealed air borne concentration of the acrylamide to be from 0.05 to 0.23 mg/m3 by personal sampling and from 7.65 to 11.65 mg/m3 by area sampling during filter exchanging process, which far exceeds TLV-TWA of 0.03 mg/m3. However, acrylamide was not detected from the plasma of the workers. Symptom questionnaire showed a markedly higher complain of neurologic symptoms, compared to the workers of the other acrylamide producing companies. Electrodiagnostic test showed a several workers are in the lower normal range without definite abnormality. Vibrotactile perception threshold by Vibratron Ⅱ showed a significantly increased threshold in the workers of the same workplace compared to the other acrylamide workers and significantly decreased test score of color vision compared to normal controls. After improvement of the production process and strict wearing of the protective device, most workers reported the improvement of clinical symptoms, but vibrotactile perception threshold was not improved. These result suggests the need for the effective environmental monitoring together with a periodic biological monitoring. Development of effective screening test is urgently needed to control and assess the skin absorption of acrylamide.

Objective: This study was designed to estimate the frequency and risk factor for edenomyosis Methods: The clinical records of 623 women undergoing hysterectomy were retrieved in the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital, during 5 years, from Jan. 1995 to Dec. 1999. Results: The following result were obtained. 1. Adenomyosis was found in 247 of 623 patients(39.6%) 2. The highest incidence was 40-49 years of age group, an incidence of 46.6% and mean age was 44.7 years. 3. Adenomyosis was more frequently observed in parous women than non-parous women, such as 93.1% and 6.9%, respectively. 4. Dysmenorrhea, metrorrhagia, pelvic pain and vaginal bleeding were common symptom of adenomyosis, an incidence of 28.7%, 19.0%, 18.2% and 16.2%, respectively. 5. Myoma was the most combined disease in adenomyosis, showing the incidence of 54.7%. 6. Grossly, the size of uterus was enlarged more than 10 weeks gestational size in adenomyosis, an incidence of 61.9%. 7. Preoperative diagnostic accuracy of adenomyosis was 6.9%. Conclusion: The results show that deeply understanding of the common symptoms and epidemiology of adenomyosis improve the preoperative diagnostic accuracy.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.
