Background: An increasing number of elderly are referred for open heart surgeries(OHS). These patients are assumed to have significantly increased morbidity and mortality because of compromised functional reserves in their vital organs. We reviewed the results of OHS patients who were 70 years old or older. Material and Method: Thirty six consecutive septuagenarians underwent OHS from 1995 to 1997. Operations were coronary artery bypass grafting(CABG) in 26 including 3 left main surgical angioplasty, valve replacement in 7, MVR+CABG in 2, and ASD closure+TAP in 1. Statistical tests were carried out to compare survivor group with nonsurvivor group in respect to risk factors including NYHA functional class, LVEF, emergent operation, IABP support, CPB/ACC time, ventilator time cardiac index, ICU stay and hospital stay for operative mortality. Result: Operative mortality rate and postoperative complication were 16%(6/36) and 50%(18/36). One-year and 3-year actuarial survival rates were 76%. Nine patients(25%) had major complications including third-degree A-V block(2), respiratory failure(1), stroke(3), renal failure requiring dialysis(3) and postoperative hemorrhage(2). The causes of death were pneumonia(1), bleeding(1), acute renal failure(1), low cardiac output(1), third-degree A-V block(1), and ventricular tachycardia(1). The univariate analysis of mortality shows that NYHA class IV, LVEF<40%, lesser values for C.I, and longer time for ventilatory support were associated with the risk factors(p value=0.03, 0.001, 0.007, and 0.014). The emergent operation, CPB/ACC time, IABP support, ICU stay and hospital stay were not significant. Conclusion: We conclude that cardiac operation can be performed in septuagenarians with acceptable outcomes when done in patients with normal to moderately depressed left ventricular function and adequate functional reserves in their vital organs.

Objective : The study investigates the extent of brain shift and its effect on the accuracy of the stereotaxic procedure. Methods : Thirty-five patients underwent 40stereotactic procedures between June 2002 and March 2004. There were 26 males, mean age 59years old. There were 34procedures for Parkinson's disease, 2 for essential tremor, 3 for cerebral palsy, 1 for dystonia. Patients were divided in four groups based on postoperative pneumocephalus : under 5cc [9 procedures], between $5{\sim}10cc$ [13procedures], between $10{\sim}15cc$ [11 procedures] and more than 15cc [7procedures]. The coordinates of the anterior commissure[AC], posterior commissure[PC], and target were defined in pre-and intraoperative magnetic resonance image scans and the amount of air volume was measured with @Target (BrainLab, Heimstetten, Germany]. Results : The mean AC-PC was 26.5mm for patients with less than 5cc, 26.9mm for $5{\sim}10cc$, 25.8mm for $10{\sim}15cc$ and 26.2mm for more than 15cc. The length of AC-PC line and coordinates of AC, PC was also not statistically different, Euclidean distance as well as ${\Delta}x$, ${\Delta}y$, ${\Delta}z$ of AC, PC, and target were also not statistically different among the groups [p>,1]. There was a variance in target of $0.7{\sim}7.6mm$, Euclidean distance of 2.5mm, related to electrophysiology but not to brain-shift. Conclusion : The amount of air accumulated in the intracranial space and compressing the cortical surface has no effect on the localization of subcortical stereotactic target and landmarks.

The main purposes of this study were to segment Chinese consumers who purchase fashion products through internet commerce according to internet shopping values, to compare their online word-of-mouth acceptance and dissemination behavior, and to examine the demographic characteristics and purchase behavior of the segments. 715 questionnaires were collected through internet survey from January $19^{th}$ to March $16^{th}$, 2015 and a total of 488 were used for the final data analysis. The respondents were twenty to thirty nine years old men and women living in all over China. Hedonic and utilitarian shopping values were identified through factor analysis and based on the shopping values, the respondents were categorized into four groups-ambivalent shopping value group, hedonic shopping value group, utilitarian shopping value group and indifferent group. Among these groups, there were significant differences in terms of online word-of-mouth acceptance as well as dissemination level and motivation. In overall, ambivalent shopping value group showed high online word-of-mouth acceptance as well as dissemination motivation. The groups also showed significant differences in clothing selection criteria, frequently purchased internet shopping sites, online clothing shopping frequency and information sources. The groups also differed in terms of age, residential area, education level, occupation and income. However, there were no significant differences in gender and marital status among the groups.

Purpose : High interleukin-1 beta(IL-$1{\beta}$) expression in the skin biopsy specimens of patients with Henoch-$Sch\ddot{o}nlein$ Purpura(HSP) has been observed. We examined IL-$1{\beta}$ gene polymorphism in patients with HSP. The purpose of this study is to examine the relationship between IL-$1{\beta}$ gene polymorphism and renal involvement in HSP. Methods : Patients from mideast Korea with HSP were studied. All patients had at least 6 months of follow up. Patients and ethnically matched controls were genotyped for IL-$1{\beta}$ gene polymorphism by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results : Thirty-four patients(all younger than 15 years old) who had been diagnosed with HSP and 27 controls were examined. No allele or genotype differences between the HSP and control groups were observed. No significant association between the carriage of IL-$1{\beta}$(-511) T allele and renal involvement(P=0.525, OR:1.417, CI:0.545-3.686) was found. Conclusion : In unselected patients with HSP, carriage of IL-$1{\beta}$(-511) T allele does not appear to influence renal involvement.

Purpose: The effect of two different levels of illumination and the effect of three letter chart types on subjective refraction findings were investigated. Methods: This study involved thirty Malay university students aged between 19 to 23 years old (7 males, 23 females), with their spherical refractive error ranged between plano to -7.75D astigmatism ranged from plano to -1.75D, anisometropia less than 1D and with no history of ocular injury and pathology. Monocular subjective refraction was measured under two levels of illumination (with and without room light) and with three different letter charts (Snellen letter chart, wall mounted letter chart and projected letter chart). Subjective refraction finding was calculated in spherical equivalent in unit diopter (D). Results: There was no significant effect in the subjective refraction findings with Snellen letter chart (t-test=0.15, p-value=0.88), projected letter chart (t-test=-0.19, p-value=0.85) as well as wall mounted letter chart (t-test=0.12, p-value=0.94). One Way ANOVA also revealed when the subjective refractive measures were compared under two different level of room illumination (with and without room light), no significant effect of letter chart types on subjective refraction readings with room light ($F_{2.185}$=0.11, p-value=0.89) and without room light ($F_{2.185}$=0.02, p-value=0.98). Conclusions: Subjective refraction findings were not affected whether the room light was on or off. They were also not affected by the types of letter chart used.

Objective : Atypical meningioma is rare tumor and there is no accurate guide line for optimal treatment. This retrospective study analyzed the prognostic factors, the effect of different methods of treatments and the behavior of atypical meningioma. Methods : Thirty six patients were diagnosed as atypical meningioma, among 273 patients who were given a diagnosis of meningioma in the period of 2002 to 2015. Age, gender, tumor location, Ki 67, Simpson grade and treatment received were analyzed. We studied the correlation between these factors with recurrence, overall survival rate and progression free survival. Results : Median overall survival time and progression free survival time are 60 and 53 (months). Better survival rate was observed for patients less than 50 years old but with no statistical significance (p=0.322). And patients with total resection compared with subtotal resection also showed better survival rate but no statistical significance (p=0.744). Patients with a tumor located in skull base compared with patients with a tumor located in brain convexity and parasagittal showed better progression free survival (p=0.048). Total resection is associated with longer progression-free survival than incomplete resection (p=0.018). Conclusion : We confirmed that Simpson grade was significant factor for statistically affect to progression free survival in univariate analysis. In case of skull base atypical tumor, it is analyzed that it has more recurrence than tumor located elsewhere. Overall survival was not affected statistically by patient age, gender, tumor location, Ki 67, Simpson grade and treatment received in this study.

The purpose of this study is to evaluate the effects of Qigong gymnastics exercise program on the physiopsychological parameter in essential hypertension. The design of the research was a one group pretest-posttest design. A total of 20 pateints with hypertension who were from forty to sixty-five years old participated in the study. The Qigong gymnastics program was carried out twice a week for thirty minutes or forty minutes for six weeks from 22, Sep. to 31, Oct. in 1997. In order to evaluate the effect of the Qigong gymnastics program physiological parameter (blood pressure, pulse rate, FVC, FEV1, Epinephrine, Norepinephrine, Cortisol) and psychological parameter(self-efficacy, Life satisfaction) were measured before and after the exercise program. Collected data was analyzed by the paired t-test with SAS package. The result are as follows : 1) There were significant decrease in systolic blood pressure and diastolic blood pressure, but there was no significant change in pulse rate. 2) There were no significant difference in FVC and FEV1 3) There were significant decrease in epinephrine, norepinephrine and cortisol. 4) There were significant improved in general self-efficacy and life satisfaction. 5) The effect of Qigong gymnastics program by measurement time on blood pressure and pulse rate were as follows : In a systolic blood pressure was gradually significant decreased from 1 week to 6 weeks and diastolic blood pressure was significantly decreased after 4weeks. But there was no significant change in pulse rate. This results suggest that Qigong gymnastics are an appropriate nursing intervention for clients with hypertension. For further research is necessary to reevaluate the effect with a letter experimental design and longer period than 8 weeks for the Qigong gymnastics program.

The purpose of this study was to verify the effectiveness of a life review-narrative group therapy program aimed at increasing ego-integrity in the elderly. The life review-narrative group therapy program was organized according to the tfe course from childhood to old age. The objectives of the program were for the elderly to enhance their self-worth, become aware of their individual self existence, accept aging and death, accept the past and present life, and to make the most of their experiences of overcoming difficulties. The counseling techniques used in the program were mainly reminiscence and re-authoring of the narrative therapy. Thirty-two elderly people aged 60 years and over (16 in each of experimental and control groups) were selected randomly from the Daegu Metropolitan City General Welfare Center for the research. The two groups were identified as equivalent for the study in a pre-test. The program of the experimental group was implemented twice a week for 90 minutes per session over a 6-week period (Sep. 8th - Oct. 14th. 2005). The pre (Sep. 8th 2005), the post (Oct. 14th. 2005) and follow-up (Nov. 14th. 2005) tests were implemented in ordo, to verify the effectiveness of the program. The instruments used in the study were the Ego-Integrity Scale. The data were analyzed using t-test, and Ore-Factor Repeated Measures ANOVA. The findings of the study were as follows. The experimental group evidenced significant effects on enhancing ego-integrity. The result of the post hoc multiple comparisons showed that the effects of the life review-narrative group therapy Program were maintained for one months. Meanwhile the control group did not show any significant change in ego-integrity. Based on these findings, the limitations of the study were discussed, and further research was suggested.
