  • Cryopreservation by vitrification of Hanwoo blastocysts derived from nuclear transfer with Hanwoo adult ear cell was compared with that of in vitro fertilized blastocysts. For vitrification, day 7 or day 8 blastocysts were serially exposed in glycerol (G) or/and ethylene glycol (EG) mixtures (10% G for 5 min, 10% G plus 20% EG for 5 min, and 25% G plus 25% EG for 30 sec) which was diluted in 10% FBS added D-PBS. Thawing of straw was carried out in air for 10 sec and then in water bath of $25^{\circ}C$ for 20 sec. The contents of the straw (0.2 ml) was expelled into a culture dish contained with 0.5M sucrose and 10% FBS(S-DPBS) by cutting the cotton plug and then the recovered embryos were put into fresh 0.25M and 0.125M S-DPBS for 30 sec, respectively, The embryos were transferred into D-PBS with 10% FBS for 5 min. and were cultured in a 10u1 droplet of co-culture environment (cumulus cell monolayer + 10% added CRl medium) for 24 h. In the result, survival rates were 88.9% and 85.4% for nuclear transfer embryos and in vitro fertilized embryos, respectively. After transfer of vitrified-thawed blastocysts produced from nuclear transfer, 4 of 5 total recipients did not return to the subsequent estrus cycle at 30 days. It is concluded that the Hanwoo blastocysts derived from nuclear transfer can be successfully cryopreserved using simple and efficient vitrification method.

  • Purpose: This paper studies the influence of the case-management program on the change of blood sugar, lifestyle, and knowledge level of diabetes mellitus (DM) for medium-sized-enterprise employees suffering from DM. Method: Subjects, divided into experimental and control groups, are 59 workers with FBS higher than 126mg/$d{\ell}$ or under DM medication treatment in the medium-sized enterprises, being managed by two distinct university hospital group occupational health management service teams. The case management program for DM patients consists of 6 different processes in which each subject is treated. Result: FBS decreased in the experimental group after the program, while that of the control group increased significantly. In the experimental group, the amount of smoking, the frequency of drinking and the amount of drinking per week decreased. Also, the knowledge level for DM and the change of nutrition management showed significant increase. In the control group, the amount of smoking increased and the frequency of drinking, the amount of drinking and nutrition level did not change significantly. And the knowledge level for DM decreased. Conclusion: We expect that taking this case management program for DM management may significantly improve diabetic patients' overall health.

  • Microbial infection provokes one of the most serious complications to the patients with indwelling catheters. Ciprofloxacin (CFX) was added into the catheter materials (polyurethane or silicone) during the manufacturing process to avoid the microbial infection. Efficacy of the catheters containing CFX was investigated by using the in vitro zone of growth inhibition test method. The catheters made of polyurethane or silicone exhibited a strong antimicrobial activity against the major catheter-related microorganisms (S. aureus, S. epidermidis, P. aeruginosa and E. coli), when CFX was incorporated into the catheters. Fetal bovine serum (FBS) did not affected antimicrobial activities of the polyurethane catheters with CFX loading of 0.5 and 1.0% (W/W) against S. aureus and S. epidermidis. However, the polyurethane catheters with 1.0% (W/W) of CFX loading showed a significantly (P<0.05) reduced antimicrobial activity against E. coli when the catheters were exposed to FBS. Silicone catheters with 1.0 and 1.5% (W/W) of CFX loading demonstrated effective antimicrobial activity against S. epidermidis for at least 2 weeks. These results suggest that the use of catheters containing ciprofloxacin could be effective in preventing catheter-related infections.

  • The aim of this study was to examine the effect of telephone follow-up on glycemic control, lipid profiles. and treatment method in diabetic patients with depressive symptoms over one year follow-up period. Twenty-two diabetic patients attended the structured diabetes education program between March 2004 and February 2005 and completed a questionnaire using the Beck Depression Inventory(BDI) to measure depressive symptoms. The patients showed depressive symptoms with the criterion being a BDI score at least 16. The intervention was applied to the telephone follow-up for one year. Data were analyzed using Wilcoxon signed rank test and McNemar test. The patients decreased their mean glycosylated hemoglobin(HbAlc) levels by 1.9%(p=0.001). There was a significant mean change in the fasting blood sugar(FBS) level, with a mean change of -61mg/$d{\ell}$(p=0.008). These findings indicated that the telephone follow-up may be effective in the HbAlc and FBS control.

  • Purpose: To investigate the level of depression and self management behavior in patients with diabetes. Method: From May to August 2004, 124 diabetic patients 18 years or older were surveyed using the Korean version of the BDI, the self-management scale by Toobert(2000) and hospital lab data for HbAl, FBS and Blood Sugar-2hr. Results: 1. Mean score on the BDI for the patients was 10.85 points. The score on the BDI was significantly higher in hyperglycemic patients than in normoglycemic patients. 2. The level of self management for the past week showed care on an average of 4.2 days. According to level of depression, patients in the normal group and patients in the mild group had significantly higher levels of self management than those in the moderate group. 3. According to level of depression, patients in the normal group had significantly lower levels of blood glucose than those in the moderate group, and for HbAlc and FBS those in the mild group had lower levels compared to those in the moderate group. 4. The factors significantly associated with level of self management were depression (25.66%) and duration of illness. Conclusion: Programs should be developed to combat depression in patients with diabetes in order to increase compliance through self care management and thus increase of blood glucose levels.

  • Researches on the FRF-based substructuring method have been mainly focused on vibratory response analysis. Present study Is concerned about the application of the method to the dynamic stress analysis of a air-conditioner compressor mounting bracket in a passenger car. This is performed by using reaction forces that can be obtained by the FRF-based substructuring method. The air-conditioner system, composed of a compressor and bracket, Is analyzed by using the FRF-based substructuring method. The experimental and numerical FRFs are combined to calculate the system responses and reaction forces at the connection point. The dynamic reaction forces plugged into the bracket FE model to compute the stresses of the bracket Dynamic strains by the present method are compared with those from strain-gage test for bracket system on shaker. The comparison shows possibility of practical usage of the method for the real problem

  • The present study including two experiments was designed to determine the effect of media containing different rare earth elements (REE) on proliferation and fatty acids accumulation in 3T3-L1 cell cultures. In Experiment 1, 3T3-L1 preadipocytes in 96-well plates ($1.5{\times}10^4cells/ml$) were cultured with Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal bovine serum (FBS) for 24 h. Then the media were changed to the following 10 different media for 48 h: DMEM containing 10% FBS for the control; the above media containing $5{\mu}M$, $10{\mu}M$ or $15{\mu}M$ of $LaCl_3$, $CeCl_3$ or the mixture of these REE chlorides. The proliferation rate of the cells was measured and compared by a non-isotope method-XTT method. In Experiment 2 the cells in 24-well plates ($1.5{\times}10^4cells/ml$) were cultured in DMEM containing 10% FBS for 7 days until confluent and then were changed to above DMEM containing dexamethasone, methyl-isobutylxanthine and insulin (DMI) for two days. Afterwards the media were changed to the 10 different media with REE supplements as in Experiment 1 and cultured for 6 days. The cells were then harvested for fatty acids analysis by gas chromatography. It was found that supplementation of La (5, 10 and $15{\mu}M$), Ce ($5{\mu}M$ and $15{\mu}M$) and the mixture REE (5, 10 and $15{\mu}M$) stimulated (p<0.05) the proliferation of 3T3-L1 preadipocytes (Experiment 1). In the differentiating 3T3-L1 cells supplementation of La ($5{\mu}M$ and $10{\mu}M$), Ce ($5{\mu}M$) and the mixture REE ($5{\mu}M$ and $15{\mu}M$) decreased (p<0.05) the concentration of monounsaturated fatty acids (MUFA) per $10^5cells$, while the supplementation of La ($5{\mu}M$), Ce ($5{\mu}M$) and the mixture REE ($15{\mu}M$) increased (p<0.05) the ratio of saturated fatty acids (SFA) to MUFA. These results indicate that the supplementation of REE to the media may affect proliferation, differentiation and lipogenesis rates of 3T3-L1 cells. However, the effect may depend upon the level or type of REE applied.

  • In this paper, the identification of connections for a vibration system has been presented using FRF-based substructural sensitivity analysis. The substructural design sensitivity formula is derived and plugged into a commercial optimization program, MATLAB, to identify connection stiffness of an air-conditioner system of passenger car. The air-conditioner system, composed of a compressor and a bracket is analyzed by using FRF-based substructural(FBS) method. To obtain the FRFs, FE model is built for the bracket, and the impact hammer test is performed for the compressor. Obtained FRFs are combined to calculate the reaction force at the connection point and the system response. Connection element properties are determined by minimizing the difference between a target FRF and calculated one. It is shown that the proposed identification method is effective even for a real problem.
