Purpose: This study was to examine the food intake and family support of patients with Coronary Artery Disease(CAD). Methods: 90 hospitalized patients who received CAD medical treatment were randomly selected. The food intake frequency and family support instrument were utilized. Collected data was analyzed by SPSS/WIN 14.0: t-test, $x^2$-test and Pearson's correlation coefficient. Results: The mean score of food intake frequency was 5.65(total mean score 97.50) which was relatively healthy food intake based on the CAD treatment guidelines. Undesirable food intake items were fruit, fish, milk etc. The mean score of family support was 2.44(range: 1 - 4). Food intake showed a significant(p < .001) positive correlation with family support. There was significant difference(p < .05) on family support according to exercise. There was significant difference(p < .05) on LDL level, one of the CAD risk factors, between first admission patients and readmission patients. Conclusion: These findings suggest that nursing intervention education programs should be developed to appropriately care for CHD patients for needed changes.

Martensitic stainless steel is commonly used in the medical implant instrument. The alloy has drawbacks in terms of strength and wear properties when applied to instruments with sharp parts. 440C STS alloy, with improved durability, is an alternative to replace 420 J2 STS. In the present study, the carbide precipitation, and mechanical and corrosion properties of STS 440C alloy are studied as a function of different heat treatments. The STS 440C alloy is first austenitized at different temperatures; this is immediately followed by oil quenching and sub-zero treatment. After sub-zero treatment, the alloy is tempered at low temperatures. The microstructures of the heat treated STS 440C alloy consist of martensite and retained austenite and carbides. Using EDX and SADP with a TEM, the precipitated carbides are identified as a Cr23C6 carbide with a size of 1 to 2 ㎛. The hardness of STS 440C alloy is improved by austenitization at 1,100 ℃ with sub-zero treatment and tempering at 200 ℃. The values of Ecorr and Icorr for STS 440C increase with austenitization temperature. Results can be explained by the dissolution of Cr-carbide and the increase in the retained austenite. Sub-zero treatment followed by tempering shows a little difference in the properties of potentiodynamic polarizations.

Objectives : Diabetic peripheral neuropathy(DPN), generally considered to be the most symptomatically distressing complication of diabetes, affects more than 50% of people with diabetes. However, no consistently effective treatment for DPN is available and patients are forced to struggle with medications that provide only partial relief. In this pilot study, we evaluated the clinical effects of Saam acupuncture for the treatment of painful DPN. Methods : A total of 10 patients with painful DPN were included in the study; 6 subjects with Saam acupuncture treatment and 4 subjects without it. Subjects were defined as having painful DPN if they had at least 2 points using total symptom score(TSS). Treatments were delivered three times a week for 4 weeks. Vitamin $B_{12}$ was orally administrated in the all subjects. At initial(0 week) and follow-up after 4 weeks and 8 weeks, all subjects underwent TSS, Michigan Neuropathy Screening Instrument(MNSI), and nerve conduction test. Results : After initial(0 week) and follow-up(8 weeks), TSS and MNSI were not significantly different between the two groups(p=0.400 and p=0.830, respectively). However, in both two groups, according to time, there was a significant difference in TSS as well as MNSI(p=0.001 and p=0.004, respectively). Conclusions : Saam acupuncture may be considered as the effective treatment for the patients of DPN although the changes of the symptoms were of limited significance in this study. Further investigations are required to elucidate the role of Saam acupuncture for the pain control of DPN.
