Purpose: The objectives of this study were to assess pain relief according to the time after kyphoplasty and to evaluate the factors affecting pain relief after kyphoplasty in the treatment of a single-level osteoporotic vertebral compression fracture. Methods: A retrospective review of 34 kyphoplasties for single-level osteoporotic vertebral compression fractures was performed. Pain relief was assessed by using the visual analogue scale (VAS) at preoperatively and postoperatively at 6 weeks, 3 months, and 6 months. Associated factors, including age, sex, pain duration, bone mineral density, and cement leakage, were evaluated using the patients' medical records. Statistical analyses were conducted using the paired t-test to assess pain relief and using the independent t-test and Pearson's correlation coefficient to evaluate the relationship between those factors and pain relief. Results: Preoperatively, the mean VAS score was 7.06. Postoperatively, it declined to 3.66 (p=0.001), 2.81 (p=0.001) and 2.24 (p=0.001) at 6 weeks, 3 months and 6 months, respectively. Also, statistically significant pain relief was observed during the periods from 6 weeks to 3 months (p=0.001) and from 3 months to 6 months (p=0.001). However, reduction of the VAS score showed no significant correlation with age, sex, pain duration, bone mineral density, or cement leakage (p>0.05). Conclusion: Our study suggests that a kyphoplasty may be effective in osteoporotic vertebral compression fracture patients with acute pain and that after the kyphoplasty, pain is reduced remarkably for 6 weeks and then continuously for 6 months.

This study provides some basic information on the improvement of diabetics' self-care activities through examining the patients' knowledge on diabetes, self-care activities, and how much they feel those activities are effective and through studying the correlation among the three factors. One hundred and fifty four patients were subjected to this study, who were treated or hospitalized in a hospital in Pusan. Researches were conducted from October 21 to November 9, 2002, and information were gathered by questionnaire and direct conversation with the patients. The data was processed through SPSS WIN 10.0 program. The Date were analyzed by descriptive statistics, ANOVA, t-test, Pearson correlation coefficient and Spearman rank correlation coefficient. The results of this study was the followings; 1) The subjects' knowledge on diabetes ranged from 6 to 23 points with a mean of 17.01 points. 2) The subjects' self-care activities ranged from 21 to 103 points with a mean of 67.72 points. That of the patients with regular treatments appeared to have the highest points (3.51) and the lowest points appeared in the measurement of sugar level in blood (2.60) 3) The subjects' feelings of effectiveness ranged from 21 to 103 points with a mean of 70.01 points. Drug therapy had the highest point (3.94) and diet showed the lowest (3.37) 4) In the general characteristics of the subjects, the more education a subject had, the more knowledge on diabetes he or she appeared to have (F=3.36, p=0.012). The self-care activities were significantly high among non-alcoholic subjects (F=4.301. p=.016). The subjects' feelings of effectiveness were higher in female patients than in male patients(t=2.132 , p=.035), and those in the ages between 51 and 60 felt more effectiveness (F=4.198. p=.003). In addition, married subjects felt more effectiveness than the unmarried (t=2.856, p=0.005), and the more education a patient had. the more effectivess he or she felt (F=2.879, p=.025). 5) In the subjects' pathological characteristic, the subjects who experienced diabetes education showed more knowledge on diabetes, more self-care activity, and more effectiveness than those without the education (t=3.193, p=.002; t=2.299, p=.023; t=2.128, p=.035). 6) As the results of the analyses of correlations among knowledge on diabetes, self-care activity, and effectiveness, the more knowledge on diabetes a patient had, the more self-care activity and the more effectiveness he or she showed (p=0.283. p=0.002; p=0.182, p=0.036). Self-care activity became higher as the feeling of effectiveness appeared higher (r=.550, p=.000). Based on the results above, several suggestions were made; 1) This study was conducted in one hospital, so it is difficult to generalize the results. It is necessary to gather more information from more patients through repeated researches. 2) The study on the other factors which can affect a patient's self-care activity is required. 3) The development of a program which improves a patient's self-care activity, knowledge on diabetes. and effectiveness is needed.

We discuss that the growth inhibition activities against root and shoot of rice plant (Oryza sativa L.) and barnyard grass (Echinochloa crus-galli) by N-phenyl-3,4,5,6-tetrahydrophthalimide (A) and N-phenyl-3,4-dimethylmaleimide (B) derivatives with changing substituents can be explained and predicted using comparative molecular field analyses (CoMPA) method. And the results show that the cross-validation value, $q^2$ at three components and Pearson correlation coefficient, $r^2$ were rice plant: shoot; $r^2=0.987$, $q^2=0.387$ & root; $r^2=0.923$, $q^2=0.307$ and barnyard grass: shoot; $r^2=0.902$, $q^2=0.535$ & root; $r^2=0.900$, $q^2=0.450$, respectively. In addition, The activities of unknown compounds were predicted by CoMFA method. From the contour map of (A) derivatives, the selective factors to remove barnyard grass takes positive charge on the benzylic carbon atom (C27), negative charged carbon atom (C29) of meta position and steric bulky groups on the cyclic imino ring (C7-C8).

Two different QSAR methods, the comparative molecular similarity indices analyses (CoMSIA) and hologram quantitative structure activity relationship (HQSAR) are studied for the fungicidal activities ($pI_{50}$) of 2-N-benzyl-5-phenoxy-3-isothiazolone derivatives against sensitive (SPC: 95CC7105) and resisitive (RPC: 95CC7303) phytophthora blight fungus (Phytaphthora capsici). According to the findings from these QSAR investigation, the cross-validation value, $q^2$ and Pearson correlation coefficient, $r^2$ in the two methods were CoMSIA: RPC; $q^2=0.675,\;r^2=0.942$, SPC; $q^2=0.350,\;r^2=0.876$ and HQSAR: RPC; $q^2=0.519,\;r^2=0.869$, SPC; $q^2=0.483,\;r^2=0.990$, respectively. Therefore, the two models of comparative statistical significance were obtained. From the CoMSIA contour maps, the important factors for selective fungicidal activity against RPC are to be expected that the lower hydrophobic and not bulkiness substituent as hydrogen bonding acceptor have to introduce to meta and para-position (C1-C6) on the phenoxy moiety. And the results of prediction suggest that HQSAR method showed higher fungicidal activity than CoMSIA method.
