The purpose of this study was to test psychometric properties Health-Related Hardiness Scale(HRHS) for Korean elderly. HRHS has been developed by Pollock to measure the effect of hardiness in individuals with actual health problems. Items were generated to measure dimensions based on theoretical definitions of health-related control, commitment, and challenge. In 1990, Pollcok and Duffy revised HRHS to be 34 items. In this study, 34-item HRHS(Pollock & Duffy, 1990) was translated into Korean and administered to 193 elderly involving in 95 hospitalized patients and 98 outpatients or healthy people. The subjects were 80 women and 112 men with an age range of 65 to 95 years(M=71 years) in whom 82.6% classified themselves as moderate or pretty active. Most subjects(80.2%) had education of elementary school or less. The 34-item HRHS consists of three subscales: control, commitment, and challenge, and was measured with 1(strongly disagree) to 6(strongly agree) Likert scale. The higher the score is, the higher people's hardiness. Factor analysis was performed to confirm whether the scale represents three sub-areas as suggested in the literature. Two factors were isolated, using principle components analysis. Two factor solution was accepted for the study since Pollock described the possibility of classifying sub-areas into two divisions. These two factors, commitment/challenge and control accounted for 31.9% of variance of the scale. Factor loadings were string, ranging from .41 to .77. The moderate correlation with task self-efficacy scale also supported the validity(r=.35, p<.05). The scale was found to be internally consistent, showing Cronbanch;s alpha of .90 for the total items with the range of .82 and .90 for three subscales. The findings revealed the potential applicability of HRHS to nursing intervention studies for elderly.

BACKGROUND: Malpositioning of the endotracheal tube within airway after intubation may results in serious complications, such as accidental extubation and inadvertent endobronchial intubation. Therefore, early detection of malposioning of the endotracheal tube is very impotant for deciding patient's prognosis. METHODS: We assessed the distance from the tip of the endotracheal tube to the carina according to the patient's age, sex, and the time, the location, and the route of intubation. The chest x-ray was taken for 333 patients (men, 226: women, 107) who were admitted to the intensive care unit of Wonju Christian Hospital from march 1, 1995 to February 28, 1996. Chest x-ray was obtained after intubation to verify endotracheal tube position. Appropriate endotracheal tube position on chest x-ray was defined as between 2 and 6 cm above the carina. RESULTS: Of the 333 intubations, 106 (31.8%) endotracheal tubes were inappropriately placed according to the chest x-ray. The percentage of malpositioned endotracheal tubes (<2 cm) was higher in women than in men (11.2% vs. 5.3%, p<0.05), with higher in night (7 PM to 7 AM) than in day (7 AM to 7 PM) (42% vs. 24%, p<0.05). Distance from the carina to the tip of endotracheal tube is 4.34 +/- 1.77cm in women and 5.23 +/- 1.64cm in men. Thus, position of the endotracheal tube in women is deeper than men (p<0.001). CONCLUSIONS: We conclude that the chest x-ray for confirmation of endotracheal tube position after endotracheal intubation may remain the standard of practice. And endotracheal tube position should be carefully assessed immediately after tracheal intubation, particularly in women and at night.

The ABO blood type was discovered by Karl Landsteiner in 1901. The frequency of occurrence of the ABO blood type in Korea was reported in the journal of the Joseon Medical Association in 1922. The status of 54 transfusions at one medical clinic in 1924 was reported at a medical congress in 1925. Many direct transfusion cases in Korea were identified by a literature search for articles published during the 1920s.

The purpose of this study was to evaluate the influence of accessibility to dental cervices of maxillary molars upon plaque control level of these areas. Fifthy-seven dental students with healthy gingiae participated in this study. Maxillary dental casts were fabricated for each participants. Using the casts, cervical accessibility was measured at the mid-palatal point of maxillary first and second molars. Cervical accessibility was defined as the perpendicular distance from the entrance of gingival sulcus to the imaginary line between the most protruded points of palatal gingiva and tooth surface, and classified into degree I(< or =0.5mm), II(>0.5mm, < or =1.0mm), III(>1.0mm, < or =1.5mm), and IV(>1.5mm). Plaque score was recorded as the distance from crest of gingival margin to the most coronal extent of plaque. Measurements of plaque score were repeated 3 times at 1-week intervals. After the baseline measurements, the participants began to use unitufted brushes on randomly assigned right or left side. Two weeks later, a session of plaque score records identical to the baseline measurements was started. The maxillary second molars showed higher cervical accessibility than the first molars(p<0.01), but the plaque scores of maxillary second molars were also higher than those of first molars(p<0.01). For the maxillary first molars, correlation between accessibility and plaque score was statistically significant, but such correlation was not found for the second molars. Use of unitufted brushes decreased the plaque score(p<0.01). Correlation between accessibility and the degree of plaque score improvement was not found. These findings suggest that cervical accessibility may influence the amount of plaque, and use of adjunctive oral hygiene devices may be helpful in maintaining optimal oral hygiene level at the areas of low cervical accessibility.

Primary aldosteronism is typically characterized by hypertension, hypokalemia, elevated plasma aldosterone concentration, and suppressed plasma renin activity. Surgieal excision of the tumor mostly cures hypertension as well as electrolyte and hormonal abnormalities in patient with aldosterone-producing adenoma. We have experienced the anesthetic management of unilateral adrenalectomy in a 32 years old male, who was diagnosed as aldosterone-producing adenoma, under the general anesthesia with careful monitoring. Postoperative recovery was uncomplicated.
