PURPOSE: The purpose of this study was to investigate psychological capital, sense of community and stress in relation to school adjustment and to identify factors influencing school adjustment in middle school students. METHODS: This study population consisted of 150 middle school students. Data were analyzed using t-test, analysis of variance, Pearson correlation coefficient, and multiple regression analysis. RESULTS: The mean score for school adjustment in middle school students was 3.68 out of 5 points. School adjustment explained 34% of the variance in sense of community (β=.39, p < .001), positive psychological capital (β=.35, p < .001), academic performance (β=.26, p < .001), and stress (β=−.21, p < .001). CONCLUSION: The results of our research suggest that sense of community is an important variable influencing school adjustment in middle school students. Therefore, to promote school adjustment in middle school students, it is necessary to develop and implement active educational strategies promoting sense of community, positive psychological capital, academic perfomance, and controlling stress.

Oral microorganisms, including pathogens together with commensals, interact with oral epithelial cells, which can lead to the activation and expression of a variety of inflammatory mediators in epithelial cells. Fusobacterium nucleatum is a filamentous human pathogen that is strongly associated with periodontal diseases. Our previous data suggest that Weissella cibaria, an oral commensal, inhibits the proliferation of periodontopathic bacteria including F. nucleatum. The aim of this study was to examine the effects of W. cibaria on the inflammatory mediators, interleukin (IL)-6 and IL-8, in KB cells stimulated by F. nucleatum. In a reverse transcription-polymerase chain reaction and an enzyme-linked immunosorbent assay, live F. nucleatum alone induced high levels of gene expression and protein release of IL-6 and IL-8, whereas W. cibaria alone did not induce IL-6 and IL-8 responses in KB cells. W. cibaria dose-dependently inhibited the increases of the IL-6 and IL-8 gene expression as well as IL-6 protein level in KB cells which was induced by F. nucleatum. Bacterial viability and its coaggregation with F. nucleatum are not essential in the inhibitory effect of W. cibaria. Visible effects of W. cibaria on the attachment and invasion of KB cells by F. nucleatum were observed. In conclusion, W. cibaria may exert immunomodulatory effects on the IL-6 and IL-8 responses to F. nucleatum-activated KB cells.

PURPOSE: This study is aimed at identifying the effects of telephone counseling as nursing support on distress, anxiety, depression, and adverse events in cancer patients undergoing their first chemotherapy. METHODS: This was a randomized controlled trial (pretest-posttest design). A total of 70 patients who showed 4 or higher distress scores were selected from the screening process. Four patients dropped out; therefore, 66 patients participated in this research. Thirty-two and 34 patients were randomly assigned to the experimental and the control group, respectively. After a preliminary survey, telephone counseling support was given to the experimental group at three time points. The post survey was done before the second cycle of chemotherapy. RESULTS: Regarding distress, both groups showed a statistically significant decrease in the scores: 3.4 for the experimental group and 1.8 for the control group (p=.002). Furthermore, the experimental group demonstrated a statistically significant decrease relative to the control group. Anxiety and depression showed no statistically significant difference between the two groups. CONCLUSION: This study concludes that nursing support through phone counseling is effective in decreasing distress in patients undergoing chemotherapy for the first time.

The purpose of this study was to develop a nutrition education website for children, especially those around the 4th-6th grade levels. Among the already existing websites providing nutritional information for children, 7 websites with comparable amounts of information were evaluated in terms of their topics, credibility, content, ease of use, and aesthetics. In addition, a survey was conducted to assess the need for nutrition information among 305 elementary students. The food pyramid was the topic offered most often on those websites. Information on nutrients, digestion, food safety, nutrition labeling, and healthy eating habits were available on the websites. Some of those websites also provided games or quizzes to attract the children's interest. However, seine of the websites did not give any information on the person responsible for providing the information, which is most important in determining the credibility of the website. Other problems were that some information was too difficult for children, and some of the websites did not provide a way to search for information. According to the survey results, the topics that children wanted to know about were 'desirable weight', 'cooking', 'correct food choice', 'weight control method', 'calories consumed during exercise' but, they did not have a high interest in 'asking questions', 'books with nutrition messages', 'under weight', 'negative effect of weight control' and 'helping hungry children'. Based on these results, we developed a new nutrition education web-site, ifood' (http://ifood.or.kr). We focused on helping children develop healthy eating habits by providing information which is easy and practical for children. However, we neither included the program to assess their dietary intake, nor provided entertaining background sounds, which children like. Also, the game section is composed mainly of quizzes. Therefore, we need to further develop exciting games to teach nutrition to children. In the near future, the newly developed website should be evaluated by children regarding understandability and coverage of the contents as well as usability and design, and then revised to improve the educational effect.

PURPOSE: Selective inhibition of multiple molecular targets may improve the antitumor activity of radiation. Two specific inhibitors of selective cyclooxygenase-2 (COX-2) and epidermal growth factor receptor (EGFR) were combined with radiation on the HeLa cell line. To investigate cooperative mechanism with selective COX-2 inhibitor and EGFR blocker, in vitro experiments were done. MATERIASL AND METHODS: Antitumor effect was obtained by growth inhibition and apoptosis analysis by annexin V-Flous method. Radiation modulation effects were determined by the clonogenic cell survival assay. Surviving fractions at 2 Gy (SF2) and dose enhancement ratio at a surviving fraction of 0.25 were evaluated. To investigate the mechanism of the modulation of radiosensitivity, the cell cycle analyses were done by flow cytometry. The bcl-2 and bax expressions were analyzed by western blot. RESULTS: A cooperative effect were observed on the apoptosis of the HeLa cell line when combination of the two drugs, AG 1478 and NS 398 with radiation at the lowest doses, apoptosis of 22.70% compare with combination of the one drug with radiation, apoptosis of 8.49 %. In cell cycle analysis, accumulation of cell on G0/G1 phase and decrement of S phase fraction was observed from 24 hours to 72 hours after treatment with radiation, AG 1478 and NS 398. The combination of NS 398 and AG 1478 enhanced radiosensitivity in a concentration-dependent manner in HeLa cells with dose enhancement ratios of 3.00 and SF2 of 0.12 but the combination of one drug with radiation was not enhanced radiosensitivity with dose enhancement ratios of 1.12 and SF2 of 0.68 (p=0.005). The expression levels of bcl-2 and bax were reduced when combined with AG 1478 and NS 398. CONCLUSION: Our results indicate that the selective COX-2 inhibitor and EGFR blocker combined with radiation have potential additive or cooperative effects on radiation treatment and may act through various mechanisms including direct inhibition of tumor cell proliferation, suppression of tumor cell cycle progression and inhibition of anti-apoptotic proteins.

Isolated ACTH deficiency is a rare cause of secondary adrenocortical insufficiency. The clinical presentation can be similar to that of primary adrenal insufficiency, but most of them may be nonspecific. A female patient of 25 months of age, complainig short stature, showed hypocortisolemia without ACTH & cortisol stimulation by insulin-induced hypoglycemia test. All the other hormone state was normal. Left hand AP view revealed delayed bone age(3 month) compared with chronological age. No radiologic abnormality was found in sella MRI and adrenal CT. Here we report a case of isolated ACTH deficiency presented by short stature.

BACKGROUND: Maternal serum prenatal quadruple screening includes testing for alpha-fetoprotein (AFP), human chorionic gonadotrophin (hCG), unconjugated estriol (uE3), and dimeric inhibin A (DIA). We evaluated quadruple screening using an automated platform and looked for any ethnic differences in the median values of each marker. METHODS: We measured the concentrations of each quadruple test analyte using the UniCel DxI 800 system (Beckman Coulter, USA) in 788 Korean mid-trimester maternal serum samples and calculated their median values using Benetech software (Benetech, Canada). We also compared the results with those obtained using the Immulite 2000 assay (Siemens Healthcare Diagnostics, USA) or ELISA (DSL, USA) in 442 samples. RESULTS: We obtained mid-trimester median values for each marker. The following are the comparative results for each test using the Immulite 2000 assay or ELISA (x) and the UniCel DxI 800 immunoassay (y): AFP, y=1.10x+0.01, r=0.925; uE3, y=0.28x+0.24, r=0.885; hCG, y=1.22x-3047.8, r=0.944; and DIA, y=0.86x+15.31, r=0.833. Assay results for each of the four markers showed good correlations. However, significant biases necessitated new median calculations of prenatal risk estimates in all four tests. CONCLUSIONS: We established gestational age-specific second-trimester median values for four markers in Korean samples using the UniCel DxI 800 immunoassay system. Despite significant bias, there were good correlations between the results obtained using the UniCel DxI 800 immunoassay and those obtained using the Immulite 2000 assay.

The efficacy of hydrocolloid occlusive dressing technique was compared with that of the conventional wet-to-dry gauze dressing technique in decubitus ulcer of stage I and II. Forty-four patients were randomly divided into two treatment groups and each received treatment according to the two different protocols. As a result, 80.8% of the hydrocolloid occlusive dressing group (group 1) and 77.8% of the conventional wet-to-dry gauze dressing group (group 2) healed completely with no statistically significant difference between the two groups. However, the time required for complete healing was shorter in group 1 with 18.9 days compared to 24.3 days in group 2. Ulcer healing speed was also slightly faster in group 1 with 9.1 mm2/day compared to 7.9 mm2/day for group 2. Average treatment time spent by a medical staff member was significantly shorter in group 1 with 20.4 minutes/day compared to 2017 minutes/day in group 2. The hospital cost of the ulcer treatment was higher in group 2 compared to group 1 even without taking into consideration the medical personnel's labor cost. These results indicate that the hydrocolloid occlusive dressing technique offers less time consuming and less expensive method of treatment compared to the conventional technique in stage I andII decubitus ulcers.
