PURPOSE: The purpose of this study was to compare smoking prevalence and risk factors of smoking between Korean and Korean-Chinese middle school students. METHODS: Data was collected from seventh and eighth grade students from 12 schools in Korea and 6 schools in China. Descriptive statistics, Chi-square test, and t test were performed. RESULTS: For data analysis 10,002 usable surveys were utilized. The smoking prevalence was higher in Korean-Chinese students than in Korean students. Risk factors, such as father smoking, friends smoking, gender, grade, academic achievement, alcohol use, and family income were associated with current smoking, and the differences in the two samples were significant. Korean-Chinese students were more likely than Korean students to have friends who smoked and a father who smoked. Smokers had a significantly higher rate of friends smoking, father smoking, and alcohol use. Korean-Chinese male students smoking prevalence was more than three times higher than Korean students. Korean students could sense a more anti-tobacco atmosphere in their environment. Korean-Chinese students were more likely than Korean students to perceive that it was easy to buy cigarettes and to smoke cigarettes in a public computer room. CONCLUSION: These results highlight the differences of smoking prevalence and risk factors between Korean-Chinese students and Korean students. The findings may help health educators and researchers to better understand adolescent smoking and risk factors cross culturally and aid in the development of more effective education programs, which could lead to preventing tobacco use among these populations.

The purpose of this project is to implement "Homecare Nursing Network System" using wireless network which was able to manage homecare service efficiently. Therefore, by completing the project of "Homecare Nursing Network System", the research team connected the headquarter and the local homecare service offices over the Internet, and built the database and application programs to operate the offices. Homecare nurses are using the PDA(personal digital assistant) in order to provide homecare nursing service, to record the patients' data, and to send and receive the data in real time. It results in improving the quality of the homecare service through the computerized knowledge-based assess and intervention algorithms. The team also has implemented the homepage to introduce the homecare office and to provide the homecare service information. "Homecare Nursing Network System" allows us to manage homecare nursing service under the computerized environment, to keep track of the homecare nursing document efficiently, to improve the quality of homecare nursing, and to expand its business territory.

OBJECTIVE: To determine the relationship between preoperative hypoalbuminemia and the development of complications after gynecological cancer surgery, as well as postoperative bowel function and hospital stay. METHODS: The medical records of 533 patients with gynecological cancer surgery at Konkuk University Hospital between 2005 and 2013 were reviewed. Serum albumin level <3.5 g/dL was defined as hypoalbuminemia. All perioperative complications within 30-days after surgery, time to resumption of normal diet and length of postoperative hospital stay, were analyzed. Regression models were used to assess predictors of postoperative morbidity. RESULTS: The median age was 49 years (range, 13 to 85 years). Eighty patients (15%) had hypoalbuminemia. Hypoalbuminemic patients had significantly higher consumption of alcohol >2 standard drinks per day, lower American Society of Anesthesiologist score, higher frequency of ascites, and more advanced stage compared with non-hypoalbuminemic patients. Overall complication rate within 30-days after surgery was 20.3% (108 out of 533). Hypoalbuminemic patients were more likely to develop postoperative complications compared to non-hypoalbuminemic patients (34.3% vs. 17.8%, P=0.022), and had significantly longer median time to resumption of normal diet (3.3 [1-6] vs. 2.8 [0-15] days, P=0.005) and length of postoperative hospital stay (0 [7-50] vs. 9 [1-97] days, P=0.014). In multivariate analysis, age >50 (odds ratio [OR], 2.478; 95% confidence interval [CI], 1.310 to 4.686; P=0.005), operation time (OR, 1.006; 95% CI, 1.002 to 1.009; P=0.006), and hypoalbuminemia (OR, 2.367; 95% CI, 1.021 to 5.487; P=0.044) were the significant risk factor for postoperative complications. CONCLUSION: Preoperative hypoalbuminemia in patients with elective surgery for gynecologic malignancy is an independent predictor of 30-days postoperative complications. Identification of this subset and preoperative optimization of nutritional status may improve surgical outcomes.

Purpose: To determine an appropriate surgical technique, it is important to predict pathological results for patientswith clinically localized prostate cancer (PCa) eligible for nerve-sparing radical prostatectomy (NSRP). Severalstudies have highlighted that serum testosterone level was associated with aggressive features of PCa. Therefore,we analyzed factors, including serum testosterone, to predict upstaging and upgrading after surgery for patientswith clinically localized PCa eligible for NSRP. Materials and Methods: We retrospectively evaluated patients who underwent radical prostatectomy (RP) betweenJanuary 2015 and May 2018 at our institution. Patients with Gleason grade group 1 or 2 on biopsy,prostate-specific antigen<10, and ≤clinical/radiologic stage T2 were included in this study. Upstaging andupgrading were defined as pathological stage≥T3a and Gleason grade group≥3, respectively. We evaluatedthe patients’ demographics and outcomes according to upstaging and upgrading after surgery. Predictive factorsfor upstaging and upgrading were analyzed using a multivariate logistic regression model. Results: Of 108 patients included in the study, upstaging and upgrading after surgery were observed in 24 (22.2%)and 36 (33.3%), respectively. Low serum testosterone level, small prostate size, and positive core number≥3on biopsy were identified as predictive factors for upstaging in multivariate analysis. Although serum testosteronewas associated with upgrading in univariate analysis, only clinical/radiologic stage and biopsy Gleason grade groupwere observed as predictive factors for upgrading in multivariate analysis. Conclusions Serum testosterone level was identified as a predictive factor for upstaging after RP for clinicallylocalized PCa eligible for NSRP.
