This study was performed to evaluate the tensile bond strength and modulus of elasticity of three permanent soft denture liners (Molloplast B , Ufi Gel C , Tokuyama ) before and after thermocycling. And their water sorption were also evaluated. Each soft denture liner was bonded to PMMA denture base resin blocks and the tensile bond strength and modulus of elasticity were measured by using universal testing machine. For the water sorption, weight measured after immersion of soft denture liners in 37+/-1degrees C water bath for 4 weeks. The results were as follows : 1. Molloplast B had the highest tensile bond strength, while Tokuyama had the lowest tensile bond strength, There was no significant difference between Tokuyama and Molloplast B in the both nonthermocycling and thermocycling. There was significant difference in tensile strength of Tokuyama before and after thermocycling(p<0.05). 2. For the modulus of elasticity, there was no significant difference between Ufi Gel C and Tokuyama in the both nonthermocycling and thermocycling. There was significant difference in modulus of elasticity of Tokuyama before and after thermocycling(p<0.05). 3. The failure modes of Molloplast B and Ufi Gel C were nainley adhesive type and that of Tokuyama was mainly mixed type in case of nonthermocycling and cohesive type after thermocycling. 4. The water sorption of each soft liners was within+/-2% in times (p<0.05) but, there was no significant difference among the soft liners in times.

Unstable microsatellite repeat sequences or DNA replication errors(RER) due to defective mismatch repair genes have been reported in a subset of sporadic colorectal tumors and in most tumors of patients of hereditary nonpolyposis colorectal carcinoma(HNPCC). To elucidate the clinicopathological correlation of these RER-positive cancers, we examined 16 cases of colorectal carcinoma of different histologic subtypes(6 cases of carcinoma with no gland formation, 5 cases of mucinous carcinoma and 5 cases of gland forming carcinoma). We detected RER in five cases. The patients with RER-positive cancers had a marked preponderance of carcinoma with no gland formations out of 6 carcinomas with no gland formation were RER-positive cancers) and of cancers proximal to splenic flexure(all of the RER-positive cases were proximal colon carcinomas). We conclude that RER-positive cancers have wiique pathologic features that may be useful for the screening and counselling of patients with hereditary colon cancers.

This study examined burdens of primary family carcgivcrs of paticnto with cerebrovascular accidents (CVA) along with related factors. In addition, their needs for support group intervention were assessed to develop a support group to reduce the burdens of caregiving. Eighty-one primary family caregivers of patients with CVAs at a general hospital in Seoul participated in this study . The patients with CVAs aged from 26 to 83 years with mean age of 63 years. About 90% of the patients had some paralysis and 56.6% suffered speech problems. Fifty-eight percent of the primary family caregivers were spouses of the patients and 80.2% were women. Primary family caregivers' burdens were assessed by the Burden Scale originally devel oped by Zarit (1980) and Novak & Geust(1989) and modified by Jang (1995) for use in Korea. The instrument consists of six subscales time-dependent burden, developmental burden, physical burden, emotional burden, social burden, and financiaI burden. The results were as follows : 1. The average of burden score was 91.7, indicating moderate to severe level of burden. The time-dependent burden was scored highest followed by physical, developmental, social, financial, and emotional burdens. 2. of the characteristics of patients, age, gender, and severity of the disease were found to be associated with the level of burden. Of the characteristics of primary family caregivers, age and educational level were significantly related to the level of burden. Time of care since the CVA and the quality of relationship between a patient and a caregiver prior to the stroke were significant situational factors affecting the level of burden. 3. The need for support group intervention for the caregivero was very high (95.1%). The earcgivcrs of patients who had a CVA for the first time showed higher levels of need compared to those of patients who had a CVA more than once. The caregivers indicated a support group held once a month near home or hospital would be welcomed. In addition, they replied that a group composed of 9 to 10 caregivers and guided by health care professionals (e.g., physicians and nurses) would be most desirable. More than 85% of the earegivers identified the areas that they wanted intervention in as follows : knowledge, skills, and resources to care for a patient with a CVA. the counsel of health care professionals, share of their experiences with those who have similar situations, stress management skills, and methods to overcome emotional isolation due to the great responsibility for a patient. Given the results, support group is expected to be an effective way to reduce the burdens of primary family caregivers of patients with CVAs. As a follow up It is necessary to examine the effect of support group intervention on the patient's recovery and rehabilitation.

Purpose: This study evaluated the effects of the Spinning Babies program applied during labor on birth outcomes and satisfaction among pregnant women. Methods: This non-equivalent control group, non-synchronized post-test only design study included 42 participants (22 in the experimental group and 20 in the control group). The Spinning Babies program was conducted four times in the experimental group during the first and second stages of delivery for 50 min per session. The program comprised performing pelvic circles on a birth ball, followed by wide squatting and adopting of open knee-chest and side-lying positions. Results: Compared with those in the control group, pregnant women in the experimental group had a significantly shorter labor time (t = - 6.64, p < .001), a higher success rate for normal vaginal delivery (χ2 = 4.86, p = .043), improved Apgar scores of newborns (z2 = - 2.18, p = .029), differences in neonatal oxygen therapy use (χ2 = 4.86, p = .043), and improved birth satisfaction (t = 11.99, p < .001). Conclusion The Spinning Babies program improves the birth environment by increasing the normal vaginal delivery success rate, as well as pregnant women’s birth satisfaction, and promotes neonatal health.

Henoch-Schonlein purpura(HSP) is a systemic small vessel vasculitis characterized by cutaneous purpura, arthritis, abdominal pain and nephritis. The characteristic rash of HSP consists of palpable purpura on the buttocks and lower extremities. Bullous lesions often appear in adults with HSP, whereas they are very rare in children with HSP. In this case report, the patient presented with arthralgia and abdominal pain and had hemorrhagic bullae as a prominent manifestation of the disease. The skin biopsy of the patient revealed typical leukocytoclastic vasculitis of dermal vessels and prominent IgA and fibrinogen deposits on capillary walls by direct immunofluorescence. We confirmed the diagnosis of HSP and observed improvement of clinical symptoms and signs within a few days after corticosteroid treatment. We therefore report a case with a review of the literature.

PURPOSE: The purpose of this study was to determine the most appropriate shelf life for sterilized products according to their packaging material. METHODS: Samples were prepared to target six nursing units in one general hospital in Seoul. After steam and E.O gas sterilization, sterilized product, samples were supplied to wards. Data collection was conducted for 3 months, after the expiration date of 3 months had passed for samples packaged with crepe paper and nonwoven wraps. For samples packaged with paper-plastic pouches, data collection conducted for 3 months when the expiration date of 9 months had passed. The sterilized products were collected and tested for microbial contamination. Identification of the storage environment was done as samples were collected. RESULTS: This study confirmed that the storage environment met international standards such as CDC, except for temperature. For steam sterilized crepe paper packaging samples and steam and E.O gas sterilized for nonwoven packaging samples no contamination in all products was found for 3 months past the expiration date. However, in the E.O gas sterilized paper-plastic pouch packaging sterile samples, Gram-positive bacilli were detected in one sample from a surgical intensive care unit at 45 weeks and another sample from an operating room at 47 weeks. Furthermore, the results did not show any microorganisms for up to 52 weeks in all products. CONCLUSION According to the results of this study, sterilized product packaging made with crepe paper and nonwoven wraps is better able an extended shelf life from 3 months to 6 months, reducing unnecessary costs.
