PURPOSE: This study was conducted to examine the relationships between the recurrence of pneumothorax with demographic and health-related risk factors. METHODS: Demographic factors (age and gender) and health-related risk factors (Body Mass Index, smoking, exercise, stress, fatigue, and morbidity from colds) were measured from 60 patients admitted to two acute care institutions due to pneumothorax. RESULTS: The study results showed significant differences in factors such as height and minutes of performing exercise per week, between the first occurrence and recurrence groups. However, other risk factors did not show significant differences between the two groups. CONCLUSION: Prevention of recurrences is important for the treatment and management of pneumothorax. More studies are required to accumulate empirical evidence for health-related risk factors and pneumothorax recurrence, as the relationship between all factors and recurrence were not obtained by the study results.

PURPOSE: The purposes of this study were to assess the oral health knowledge of nursing staff in long-term care institutions and to identify predictors of oral health knowledge. METHOD: For this descriptive correlation study, a self-administered and structured questionnaire was used. Respondents were 111 nursing staff in two long-term care facilities and two long-term care hospitals located in G metropolitan area and C province in the Southern part of Korea. Descriptive statistics, t-test or ANOVA, and stepwise multiple regression analysis were used to analyze the data. RESULTS: Participants in this study did not have many opportunities to learn about oral health care for elders in long-term care institutions. The percentage of correct answer for oral health knowledge questionnaire was 64.5%. Predictors of oral health knowledge among nursing staffs were education on oral health in long-term care institutions, type of institution, and length of time working with elders. These three variables accounted for 24.2% of variance in oral health knowledge. CONCLUSIONS: Nursing staffs should make an effort to improve their knowledge of oral health. Moreover, oral health educational program for nursing staffs working with elders in long-term care institution is need to be developed and the effectiveness of this education needs to be evaluated.

PURPOSE: The aim of this study was to determine the role of the CT scan in blunt hepatic injury and the significance of CT degree of hepatic injury in the decision making of treatment plan. MATERIALS AND METHODS: We retrospectively analysed the CT findings of 22 patients with hepatic injury. We graded hepatic injury on CT scan into five according to the severity. Clinical records, type of management and clinical outcome of the patients were also reviewed. RESULTS: Of the 22 patients, 17 had conservative treatment and five had surgery. The numbers of patients treated conservatively were 0, 4, 11, 2 and 0 in the grade 1, 2, 3, 4 and 5, respectively and the numbers of surgically treated cases were 0, 0, 3, 2 and 0 respectively. There was no significant statistical difference between surgically and conservatively treated groups(p-value > 0.05). All patients with conservatively treated group were hemodynamically stable and had no complication during hospitalization. Hemoperitoneum was observed in 11 of 22 patients. CONCLUSION: In blunt hepatic injury, CT plays an important role in the demonstration of location and extent of the hepatic injury, size of hemoperitoneum and the post operative course. However, we believe that physiologic status of the patients may be more important than the extent of CT based hepatic injury for determining a mode of treatment.

PURPOSE: To identify current status of university health care program. METHODS: Data and information from homepages of 309 colleges or universities in South Korea were collected. The data was analyzed by frequencies, t-test, chi2 test with SPSS Ver. 18.0. RESULTS: 117(37.9%) universities had organization of health care. Whether university had health care program or not had shown significantly depended on number of students, types of school (university or college), region, and existence of medical and nursing course. Medical course was shown as a strong predictor for facilitating university health care program limitedly focusing on diseases treatment. Health promotion programs have been operated in 15 universities, vaccination programs in 10 universities, and health screening in 20 universities. CONCLUSION: It is strongly recommended to revise the School Health Law for constructing a comprehensive university health care program consolidating health counseling and physical training.

The aim of this study is to compare the adaptability of thermoplasticized injectable gutta-percha technique to the canal walls in ribbon-shaped canals. Thirty resin models simulated ribbon-shape canals were instrumented to #40 using .06 taper Profile systems. Three groups of each 10 resin models were obturated by the lateral condensation technique(LC) and the two thermoplasticized injectable gutta-percha technique; Ultrafil Endoset+Obtura II(EO) and Ultrafil Firmset(UF), respectively. After resin model were kept at room temperature for 4 days, they were resected horizontally with microtome at 1, 2, 3, 4 and 5mm levels from apex. At each levels, image of resected surface were taken using CCD camera under a stereomicroscope at x40 magnification and stored. Ratio of the area of gutta-percha was obtained by calculating area of gutta-percha cone to the total area of canal using digitized image-analyzing program. The data were collected then analyzed statistically using One-way ANOVA. The results were as follows. 1. At 1mm levels, there was no statistically significant difference in the mean ratio of gutta-percha among the groups. 2. At 2mm level, EO showed the highest mean ratio of gutta-percha (p<0.05) and there was no significant difference between LC and UF. 3. At 3, 4, 5mm levels, EO and UF had significantly greater mean ratio of gutta-percha than LC(p<0.05) and there was no significant difference between EO and UF. In conclusion, the thermoplasticized injectable gutta-percha techniques demonstrated relatively favorable adaptability to canal walls than lateral condensation technique in ribbon-shaped canals except for 1mm level.

more efficient tooth movement. The purpose of this study was to evaluate the effect of different static magnetic fields of ND-Fe-B magnet on MC3T3-E1 cells by measuring the alkaline phosphatase activity and observing the amount of stained alkaline phosphatase. For measuring of alkaline phosphatase activity, MC3T3-E1 cells were seeded in first and third row of 12 well culture plate. And Nd-Fe-B magnets were positioned under the first column of first and third row to apply different static magnetic fields(first column:100mT ; second column:4.6mT ; third column:0.5mT ; forth column:0.0mT) to the cells for 7, 13, 19, and 25 days. For staining of alkaline phosphatase, MC3T3-E1 cells were seeded in 100mm culture plates. And Nd-Fe-B magnets were positioned under the corner of plates to apply different static magnetic fields(magnet side:100mT ; the opposite side:0.5mT) to the cells for 7, 13, 19 and 25 days. The results were as follows : 1. ALP activity was increased until day 19 in biochemical determination as well as in histochemical staining. 2. The application of higher magnetic field(100mT) suppressed ALP activity at day 13, 19, 25. On the contrary, the application of the lower magnetic field(4.6mT, 0.5mT) significantly enhanced the ALP activity. 3. Consistent with enzyme assay, histochemical staining of ALP also demonstrated that higher magnetic field(100mT) suppressed ALP activity, lower one(0.5mT) enhanced.

Purpose of the present study was to find the optimal ovulation induction medicine for the maturation and development of immature oocytes and culture media for 2-cell embryos in the mouse model. ICR female mouse aged 6 to 8 weeks, were stimulated with 5 IU PMSG injection. At 47 to 50 hour post-PMSG injection, ovaries were dissected out and oocytes-cumulus complexes were punctured. The oocyte-cumulus complexes were cultured in media containing various ovulation induction medicine, CC, HMG and Metrodin for 18 hours. Female ICR mice were stimulated with 5 IU PMSG and 48 hours later were injected 5 IU of hCG, then female and male mice were mated. At 48 hour post-hCG injection, oviducts were dissected out and 2-cell embryos were flushed. The 2-cell embryos were cultured in various media, Ham's F-10 media of milli-Q water (3degrees), Ham's F-10 media of HPLC (high performance liquid chromatography, Baxter) water, Medicult media, HTF (human tubal fluid) media for 96hours. The results were as follows. 1. When the oocytes-cumulus complexes were cultured in 10(-9)microgram/ml~ 10(-8)microgram/ml of CC, those were suppressed in meiotic maturation (28.2~ 33.7%). Whereas the oocytes-cumulus complexes were cultured in 10(-7)microgram/ml~10(-4)microgram/ml, these were not effected in meiotic maturation (54.5~72.7%). 2. When the oocytes-cumulus complexes were cultured in 10(-4)microgram/ml~ 10(-1)microgram/ml of Metrodin, those were suppressed in meiotic maturation (35.7~ 41.5%). Meanwhile the oocytes-cumulus complexes were cultured in 10(-7)microgram/ml~10(-5)microgram/ml, those were not effected in meiotic maturation (54.2~ 70.3%). 3. When the oocytes-cumulus complexes were cultured in 10(-5)microgram/ml~ 10(-4)microgram/ml of HMG, those were suppressed in meiotic maturation (48.2~ 50.4%). As being cultured in 10(-7)microgram/ml~10(-6)microgram/ml, increased in meiotic maturation (75.8~80.7%). 4. When the 2-cell embryos were cultured in Ham's F-10 media of milli-Q wats. ( 3degrees), Ham's F-10 media of HPLC (high performance liquid chromatograpy, Banter) water, Medicult media, HTF (human tubal fluid) media, developmental rates to blastocyst and hatching for 96 hour were 50.0%, 45.2%, 71.5% and 95.6%, respectively.

PURPOSE: This study was conducted to compare the recovery state of 6 month between s-ICH and s-SAH patients. The patients' recovery state was measured with 2 dimensions: functional and cognitive. METHODS: Non-experimental prospective design was adopted by including 108 hemorrhagic stroke patients(s-ICH: 52 vs s-SAH: 56) admitted to Intensive Care Unit of one university hospital. RESULTS: The study results showed that overall functional recovery state of s-SAH patients was better than that of s-ICH patients, and s-SAH patients also showed better recovery states in all of the sub-dimensions of functional recovery, such as feeding, grooming, and toileting, than those of s-ICH in 6 month. On the contrary, the study results showed that overall cognitive recovery states of 6 month between two groups were not significantly different. However, according to the results comparing the sub-dimensions of cognitive recovery, s-SAH patients' recovery states on attention, communication and memory were significantly better than those of s-ICH patients, while recovery states on problem solving, safety behavior, and social behavior between 2 groups were not significantly different. CONCLUSION: From the study results, it was noted that s-SAH patients showed better recovery states in cognitive dimension as well as in functional dimension compared with s-ICH patients.
