PURPOSE: The purpose of this study was to examine types of parenting among fathers. The characteristics of parenting each type in early childhood were identified by systematically analyzing and classifying father's perceptions of parenting using the Q-methodology, which places importance on the perspective of the performer. METHODS: The Q-method, which is effective for measuring individual subjectivity was used. The subjects in this study were 50 fathers with young children (2~36 months). RESULTS: Four parenting types were identified analyzing the subjective perceptions of fathers with young children about parenting. One type was centered on character development. Another was centered on social development. A third was centered on physical health and development. The fourth was centered on building values. CONCLUSION: Parenting education programs should be developed based on type-specific characteristics and further research should investigate the effects of father's parenting type.

OBJECTIVES: This study examined the effect of 2% chlorhexidine on the microTBS of a direct composite restoration using one-step self-etch adhesives on human dentin. MATERIALS AND METHODS: Twenty-four extracted permanent molars were used. The teeth were assigned randomly to six groups (n = 10), according to the adhesive system and application of chlorhexidine. With or without the application of chlorhexidine, each adhesive system was applied to the dentin surface. After the bonding procedure, light-cure composite resin buildups were produced. The restored teeth were stored in distilled water at room temperature for 24 hours, and then cut and glued to the jig of the microtensile testing machine. A tensile load was applied until the specimen failed. The failure mode was examined using an operating microscope. The data was analyzed statistically using one-way ANOVA, Student's t-test (p < 0.05) and Scheffe's test. RESULTS: Regardless of the application of chlorhexidine, the Clearfil S3 Bond showed the highest microTBS, followed by G-Bond and Xeno V. Adhesive failure was the main failure mode of the dentin bonding agents tested with some samples showing cohesive failure. CONCLUSIONS: The application of 2% chlorhexidine did not affect the microTBS of the resin composite to the dentin using a one-step self-etch adhesive.

The purpose of this study was to evaluate the effect of additional etching procedure prior to Maxcem resin cement application in indirect restoration cementation using push-out bonding strength. One hundred and two extracted human molars were used to make indirect resin restorations of gold inlay and Synfony. These restorations were cemented using Maxcem and Variolink II. Additional etching procedures were done for one group with Maxcem. Three groups have 17 specimens in both restoration types. Push-out bond strength was measured using multi-purpose tester and calculated for bonding strength per sqaure-millimeter area. The mean bonding strength values were compared using SPSS 12.0K program for one-way ANOVA and Scheffe's Test with 95% significance. Under the condition of this study, the additional etching procedure prior to usage of Maxcem resulted in reduced bond strength for both of restoration types.

BACKGROUND: Cystic neoplasms of the pancreas are being recognized with increased frequency. In 1993, a report on 123 cases of cystic neoplasms of the pancreas diagnosed over a period of 32 years was published in Korea. Many changes on the concept of cystic neoplasms of the pancreas have been made, including classification and diagnostic criteria. The present study was conducted wherein a new survey on cystic neoplasms of the pancreas in Korea. METHODS: Cystic neoplasms of the pancreas diagnosed over a period of 12 years, from 1993 to 2004 in 25 university hospitals throughout Korea were collected. They were classified according to the World Health Organization classification of cystic neoplasms of the pancreas. RESULTS: A total of 1264 cases of cystic neoplasms of the pancreas were diagnosed. The diagnoses and frequencies are as follows: intraductal papillary mucinous neoplasm, 499 (39.5%); mucinous cystic neoplasm, 318 (25.2%); serous cystic neoplasm, 232 (18.4%); solid pseudopapillary neoplasm, 192 (15.2%); cystic endocrine neoplasm, 11 (0.8%); lymphoepithelial cyst, 8 (0.6%); acinar cell neoplasm, 3 (0.2%); mature teratoma, 1 (0.1%). Increase in the annual number of diagnoses was evident. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, a significant increase in mean age was seen in patients with malignant neoplasms. CONCLUSIONS: Cystic neoplasms of the pancreas are diagnosed with increasing frequency in Korea, the most common being intraductal papillary mucinous neoplasm of the pancreas. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, the grade of dysplasia increased with mean age, suggesting an adenoma-carcinoma sequence.

OBJECTIVE: The aim of this study is to evaluate the acceleration of the center of mass (COM) of the body in stroke patients. METHOD: Seventeen stroke patients and 9 normal subjects were participated. Three dimensional gait analysis was used to classify gait phases for the reference. The accelerometer held over the COM were used to record vertical and medio- lateral accelerations of the COM of the body. Modified Ashworth scale and Brunnstrom stage were used to evaluate the clinical status of stroke patients. RESULTS: In normal subjects, the acceleration showed symmetric pattern. The maximum peak of vertical acceleration occurred in loading response. In stroke patients, the acceleration wave was characterized by asymmetry and polyphasicity. Maximum peak in affected side was higher than that in unaffected side (p<0.05). There were significant correlations between several elements of hemiplegic gait and the correspondent acceleration values; interval of successive peak I in vertical acceleration vs. step time, walking velocity and swing symmetry ratio vs. mean peak I, swing symmetry ratio vs. affected side peak I, step length symmetry ratio vs. peak I symmetry ratio. CONCLUSION: The accelerometer can be an easy and useful way to evaluate gait characteristics in stroke patients.

BACKGROUND: Bronchial asthma is characterized by a reversible airway obstruction, airway hyperresponsiveness, and eosinophilic airway inflammation. The bronchodilator response(BDR) after short acting beta agonist inhalation and PC20 with methacholine inhalation are frequently used for diagnosing bronchial asthma, However, the relationship between the presence of a bronchodilator response and the degree of airway hyperresponsiveness is uncertain. Therefore, the availability of a eosinophil cationic protein(ECP) and a correlation ECP with a bronchodilator response and airway hyperresposiveness was investigated. METHOD: A total 71 patients with a moderate to severe degree of bronchial asthma were enrolled and divided into two groups. 31 patients with a positive bronchodilator response and 38 patients with a negative bronchodilator response were evaluated. In both groups, the serum ECP, peripheral blood eosinophil counts, and total IgE level were measured and the methacholine bronchial provocation test was examined. RESULTS: There were no differences observed in age, sex, atopy, and baseline spirometry in both groups. The peripheral eosinophil counts showed no difference in both groups, but the ECP level in group 1 (bronchodilator responder group) was higher than in group 2(non-bronchodilator responder group) (22.4±20.7 vs 14.2±10.4, mean±SD). The PC20 in group 1 was significantly lower than in group 2 (1.14±1.68 vs 66±2.98). There was a significant positive correlation between the BDR and ECP, and a negative correlation between the bronchial hyperresponsiveness and ECP. CONCLUSION: The bronchodilator response significantly correlated with the bronchial hyperresponsiveness and serum ECP in the moderate to severe asthma patients. Hence, the positive bronchodilator response is probably related with active bronchial inflammation and may be used as a valuable index in treatment, course and prognosis of bronchial asthma.

To determine whether the tumor cell contamination of peripheral blood stem cells influences clinical impacts on high-dose chemotherapy in patients with metastatic breast cancer, we analyzed carcinoembryonic antigen (CEA) mRNA in the apheresis products by nested RT-PCR (reverse transcriptase-polymerase chain reaction). A total of 38 metastatic breast cancer patients and ten normal healthy subjects as a negative control were included. Twenty out of 38 (51.3%) apheresis products from patients with metastatic breast cancer were positive for CEA mRNA. CEA mRNA was noted in 54.8% (17/31) of patients mobilized with chemotherapy plus G-CSF and 42.8% (3/7) of patients with G-CSF alone. There was no significant difference in age, estrogen receptor, menopausal status, mobilization method, disease free interval, or number of metastasis sites (1 vs >/=2) between positive and negative groups. The presence of CEA mRNA in apheresis products did not influence the time to progression and overall survival in both groups. However, both the univariate and the multivariate analysis disclosed that the number of metastasis was associated with survival significantly. We suggest that the tumor cell contamination does not predict poor treatment outcome in patients with metastatic breast cancer.

Recently we have experienced one case of pulmonary lymphangioleiomymatosis(LAM). A 49 year-old woman visited the outpatient department complaining of longstanding dyspnea, which was aggravated by exercise. Although the chest PA film showed nothing more than a slight increase in interstitial marking, a lung HRCT revealed multiple cystic lesions of a similar size that were scattered through out the whole field in both lungs. An abdominal CT detected an angiomyolipoma located in the midbody of the left kidney. Video-assisted thoracic surgery(VATS) was performed for the pathologic diagnosis. On gross examination of the biopsy lung, a pulmonary LAM was confirmed by a finding of smooth muscle proliferation in the interstitum of the lung. After the final diagnosis, oral medroxyprogesterone was prescribed and she is presently in a stable condition.

Anticonvulsant hypersensitivity syndrome(AHS) is an uncommon, but potentially fatal, multi-systemic disorder that occurs after exposure to phenytoin, carbamazepine, phenobarbital. Clinical features and laboratory data are diverse and variable. The multi-systemic reaction presents as fever, skin eruptions, lymphadenopathy, hematologic abnormality, and hepatitis. It is postulated that this mechanism can cause deficient enzymatic reduction by epoxide hydrolase. The diagnosis of AHS is made by reviewing the history of drug exposure and clinical course. It is important to discontinue use of the offending drug suspected for AHS and to closely observe patients with anticonvulsant therapy. We experienced a case of anticonvulsant hypersensitivity syndrome developed by carbama-zepine, presented with pseudolymphoma in lymph node biopsy and improved by discontinuing the drug and implementing steroid treatment. We report this case with pathologic findings and a brief review.

OBJECTIVE: Cardiopulmonary exercise test is a useful tool to evaluate the operative risk and to plan exercise treatment for the patients with chronic obstructive pulmonary disease(COPD). In cardiopulmonary exercise test, most of the measured parameters are recorded at the time of peak exercise, which are hard to attain in COPD patients. So we evaluated the usefulness of the parameter, breathing reserve index(BRI=minute ventilation [VE]/maximal voluntary ventilation[MVV]) at the time of anaerobic threshold(BRIAT) for the differentiation of COPD patients with normal controls. METHODS: Thirty-six COPD patients and forty-two healthy subjects underwent progressive, incremental exercise test with bicycle ergometer upto possible maximal exercise. All the parameters was measured by breath by breath method. RESULTS: The maximal oxygen uptake in COPD patients (mean+/-SE) was 1061.2+/-65.6ml/min which was significantly lower than 2137.6+/-1.4ml/min of normal subjects(p<0.01). Percent predicted maximal oxygen uptake was 54.3% in COPD patients and 86.0% in normal subjects(p<0.01). Maximal exercise(respiratory quotient; VCO2/VO2 > or =1.09) was accomplished in 7 of 36 COPD patients(19.4%) and in 18 of 42 normal subjects(42.9%). The BRIAT of COPD patients was higher(0.50+/-0.03) than that of control subject(0.28+/-0.02, p<0.01), reflecting early hyperventilation in COPD patient during exercise. The correlation between BRIAT and BRI at maximal exercise in COPD patients was good(r=0.9687, p<0.01). CONCLUSION: The BRIAT could be a useful parameter for the differentiation of COPD patients with normal controls in the submaximal cardiopulmonary exercise test.
