In order to reduce environmental pollution by pear slurry from pear juice processing and further, develop new valuable sauces, pear pastes was prepared using pear slurry and its quality characteristics was investigated with physiological functionality. Pear paste contained 29.1% of carbohydrate, 1.0% of crude protein and 0.25% of crude fat, and also fructose content and edible fiber content were 16.42mg/100ml and 0.5g/100ml, respectively. Anti-obesity α-glucosidase inhibitory activity of the pear pastes was 20.0% and antihypertensive angiotensin I-converting enzyme inhibitory was increased to 17.9% from 4.0% during storage at 20℃ for 2 weeks.

19 adult ALL patients were treated with follwing regimens; VP regimen to 5 patients, VPA regimen to 4 patients, multi-drug combined intensive therapy of Hoelzer regimen to 10 patients. The results of therapy are as follows: 1. Complete remission occured in 3 patients on VP regimen(60%), 4 patients on VPA regimen (100%), 8 patients on Hoelzer regimen (80%), respectively, and overall complete remission rate was 78.9%. 2. Mean survival time of total patients was 13.8 months, and in complete remission group, it was 16.2 month, but in non-complete remission group, it was 1.8 month. 3. Factors favorable for complete remission were absence of organomegaly(P<0.05) and initial leukocyte count under 30,000/㎟(P<0.01), factors favorable for the survival duration were initial leukocyte count under 30,000/㎟(P<0.05) and remission within 4 weeks of treatment.(P<0.01). 4. Recurrence rate were 40% in VP regimen, 50% in VPA regimen, and 20% in Hoelzer regimen. 5. During the remission induction period, common side effects of chemotherapy were alopecia, nausea, vomiting, mucositis, and general weakness and it was severe in VPA regimen and Hoelzer reimen than in VP regimen. But no significant difference was noted between VPA regimen and Hoelzer regimen. From the above results, we could confirm the importance of multiple drug combined intensive chemotherapy of remission regimen and periodic reinduction chemotherapy.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

Metallothionein (MT), a small protein molecule which can bind of release metal tons, is involved in the regulation of cellular metal homeostasis This study was investigated the accumulation of cadmium in blood, tissue (liver, kidney and brain), and the effect of cadmium on several key genes (MT-Ⅰ, MT-Ⅱ, ZnT-1) in zinc metabolism m the mouse Mouses weighing 20-25g were randomly assigned to control and cadmium treated group (Cd group) Cd group was intraperitoneally injected with cadmium 2, 4, 8 mg/kg and control group was administerd with saline Mouses of each group were sacrificed by decapitation 4 hours after the administration of cadmium Cadmium contents in blood, fiver, kidney and brain were increased by a dose-dependent manner Accumulation of cadmium was mainly occurred in liver and kidney Induction of MT-I and MT-11 protein was increased, but ZnT-1 expression was decreased to a dose-dependent manner by the treatment of 2~8mg/kg cadmium These results suggested that cadmium can be transported to brain and alter the expression of several key genes in zinc homeostasis.

As method in control CO₂ exhaust, CO₂ recovery is used. In this study, it is investigated about CO₂ recovery by absorbtion. We used packing tower(D=50mm, H=1.40m) for experimental apparatus on the chemical absorbtion being used extensively as recovery technique of CO₂. As a result of study on factor influencing absorption efficiency, it is used the absorbent MEA and AMP and it is proved that MEA have higher overall mass transfer coefficient than AMP in same concentration and condition. In the absorption break test, the concentration increase of absorbent in 150 [ℓ/hr] of gas load, 20 [I /hr] of liquid load and 15% of inlet CO₂ concentration was, when MEA was 1.64, 3.27, 4.91 M breakpoint was 120, 210, 345 minute respectively, when inlet CO₂ concentration was 10, 20, 30% breakpoint was 280, 215, 180 minute, when gas flow increase to 100, 150, 200 [ℓ/ hr], breakpoint was 230, 180, 140 minute, at result, the increase of absorbent concentration, inlet CO₂ concentration and gas load give rise to fast breakpoint.
