  • Prenatally diagnosed neuroblastomas have been reported in increasing numbers over the past several years. The vast majority are in favorable stages of the disease (stage I, II, IV-S). The authors experienced one case of stage IV-S neuroblastoma of the adrenal gland with liver metastasis, which regressed spontaneously after removal by adrenalectomy. This patient was noticed to have an abdominal mass at prenatal ultrasonography performed at 36weeks of gestation. This tumor was a neuroblastoma of the left adrenal gland with multiple liver metastases. Left adrenalectomy and liver biopsy were performed at 3 months of age. Thirty-eight months after surgery, an MRI demonstrated that the hepatic metastatic lesions had completely regressed without chemotherapy or radiation.

  • This study aims to investigate the interplay between education and local roads on Foreign Direct Investment (FDI) in the Philippines, using economic growth as an instrument. The study used the quantitative research design applying both descriptive and inferential statistics. A combination of Two Stage Least Square Regression Model and three approaches in Panel Regression Model such as Pooled Least Square, Fixed Effect Model, and Random Effect Model were utilized in order to study the effects of education and local roads on foreign direct investment of the Philippines. Based on Fixed Effect regression results, higher education graduates and local road investments, as conditioned by economic growth, were significant factors in order to increase the foreign direct investment in the Philippines. Accordingly, a unit increase in higher education graduates, as conditioned by economic growth, leads to 8.758 unit increases in the foreign direct investment. While, a unit increased in local road investments, as conditioned by economic growth, leads to a 0.002 decrease in foreign direct investment. The regression results of the study suggest that the Foreign Direct Investment in the regions such as CAR, I, II, IV-B, V, VIII, IX, X, XI, XII, XIII, and ARMM are higher compared to Region IV-A.

  • The study investigates the factors affecting the profitability of listed commercial banks in Vietnam. Survey data for this research were collected from 10 Vietnamese listed commercial banks for the period from 2008 to 2018. In the study, we have built a model of econometric regression with the dependent variable being listed commercial banks' profitability results measured through ROA. The research methods used include descriptive statistics, IV regression and OLS regression analysis, and the authors carried out the model verification with Stata 14 software. The results showed that operating efficiency, loans size, retail loans ratio, state ownership, inflation rate, and GDP growth are factors that have a positive impact on profitability On the other hand, variables such as capital size, credit risk, liquidity risk, bank size, and revenue diversification are statistically insignificant; hence, these variables are not statistically adequate to indicate the influence of those independent variables to banks' profitability. The findings of this study suggest that the quality of assets should be considered in the context that bad debt risks come from lending heavily to the real estate sector. Meeting Basel II's capital compliance requirements is relatively difficult for small listed commercial banks compared to bigger listed commercial banks in Vietnam.

  • Weight and elongation changes of IV and HIV insulations were measured simultaneously at several given temperature of $80^{\circ}C$, $90^{\circ}C$ and $100^{\circ}C$. And the lifetime was predicted using the Arrhenius model. Based on the initial weight values, a 50% elongation reduction was seen at 6.96% for the IV insulation and 10.29% for the HIV insulation. The activation energy from the slope of the lifetime regression equation was calculated as 92.895 kJ/mol(0.9632 eV) for the IV insulation and 95.213 kJ/mol(0.9873 eV) for the HIV insulation. Also, the expected lifetime at the operating temperature of $30^{\circ}C$ to $90^{\circ}C$ is 2.02 to 94.32 years, and longer lifetime was predicted on HIV insulated wires than on IV insulated wires. As a result, it was found that the thermal characteristics of the HIV insulated wires were about 12.44% better than those of IV insulated wires under the same conditions of use.

  • Objectives: This study aimed to investigate the effect of clinical clerkship-associated achievements, such as performance of procedures at the student clinic, observation, and attitude towards a clerkship, on the objective structured clinical examination (OSCE) scores of dental students graduating in restorative dentistry. Materials and Methods: The OSCEs consisted of two stations designed to assess students' clinical skills regarding cavity preparation for a class II gold inlay and a class IV composite restoration. The clerkship achievements, consisting of the number of student clinical procedures performed, observation-related OSCE, and scores of their attitudes towards a conservative dentistry clerkship, were assessed. Correlation and multiple regression analyses were conducted. Results: The correlation coefficient between the OSCE scores for cavity preparation for a class II gold restoration and clerkship attitude scores was 0.241 (p < 0.05). Regarding a class IV composite restoration, OSCE scores showed statistically significant correlations with the observation (r = 0.344, p < 0.01) and attitude (r = 0.303, p < 0.01) scores. In a multiple regression analysis, attitudes towards a clerkship (p = 0.033) was associated with the cavity preparation for a class II gold inlay OSCE scores, while the number of procedure observations (p = 0.002) was associated with the class IV composite restoration OSCE scores. Conclusions: The number of clinical procedures performed by students, which is an important requirement for graduation, showed no correlation with either of the OSCEs scores.

  • Purpose: This study was conducted to examine the clinical factors which affected the amount and the duration of infusion of intravenous (IV) heparin on ischemic stroke. Method: A cross-sectional descriptive study was designed to examine the factors. A total of 101 patients with ischemic stroke from a University hospital in G-city, Korea from January to December, 2006 were participated in this study. Data were analyzed by t- and ANOVA test, correlation coefficient, and stepwise multiple linear regression analysis. Result: This study showed that the patients who have been temporarily stopped to infuse iv heparin for more than one hour, had cardioembolic stroke, and had the lower count of initial red blood cell (RBC) had significantly lower amount of iv heparin infusion per body surface. In addition, this study founded that the patients with lower count of initial RBC and the lower level of initial blood sugar were significantly less likely to have the lower length of iv heparin infusion. Conclusion: Continuous monitoring and controlling the count of RBC and the level of blood sugar are needed to increase the efficacy of iv heparin therapy on ischemic stroke. Further empirical studies should be conducted to support the results of this study.

  • Purpose: The aim of this study was to identify the effect of an observation window (OW) at peripheral intravenous (IV) catheter sites on early detection of IV infiltration among hospitalized children. Methods: This was a retrospective observational study with history control group design. Participants were children who had IV infiltration after peripheral catheterization when hospitalized from January to May, 2014 and January to May, 2015 at a children's hospital located in Yangsan city, Korea. The 193 patients, who were hospitalized from January to May, 2014 formed the control group and did not have OW, and the 167 patients, who were hospitalized from January to May, 2015 formed the window group and had OW. Data were analyzed using ${\chi}^2$-test, independent samples t-test and multiple logistic regression. Results: First stage IV infiltration was 39.5% for the window group and 25.9% for the control group, which was significantly different (p=.007). The likelihood of $2^{nd}$ stage and above IV infiltration decreased by 44% in the window group, which was significantly different (p=.014). Conclusion: OW at the peripheral IV catheter site was found to be an effective measure in early recognition of IV infiltration. Considering the effect of OW, we recommend that nurses should make an OW with transparent dressing during stabilization of the IV catheter site in hospitalized children in clinical settings.

  • Purpose: The purpose of this study was to identify factors that influence medication adherence in colorectal cancer patients receiving oral chemotherapy. Methods: One hundred and nine colorectal cancer patients receiving oral chemotherapy were recruited in the cross-sectional survey design. A survey including medication adherence, knowledge about chemotherapy, self-efficacy, depression and symptom experience were completed. Results: The level of medication adherence was $7.38{\pm}.80$. Medication adherence showed significant differences according to perceived health status and combination of IV chemotherapy. Medication adherence was significant correlated with self-efficacy, depression and symptom experience. On stepwise regression analysis, the most important factors related to the medication adherence were symptom experience, perceived health status and combination of IV chemotherapy. These variables explained 17% of medication adherence. Conclusion: The level of medication adherence in colorectal cancer patients receiving oral chemotherapy was relatively high. It is important to develop nursing intervention for medication adherence in colorectal cancer patients that focus on symptom experience and to consider about perceived health status and combination of IV chemotherapy.

  • Background: In this study, we analyze the performance of the Acute Physiology and Chronic Health Evaluation (APACHE) II, APACHE IV, Simplified Acute Physiology Score (SAPS) 3, and Mortality Probability Model $(MPM)_0$ III in order to determine which system best implements data related to the severity of medical intensive care unit (ICU) patients. Methods: The present study was a retrospective investigation analyzing the discrimination and calibration of APACHE II, APACHE IV, SAPS 3, and $MPM_0$ III when used to evaluate medical ICU patients. Data were collected for 788 patients admitted to the ICU from January 1, 2015 to December 31, 2015. All patients were aged 18 years or older with ICU stays of at least 24 hours. The discrimination abilities of the three systems were evaluated using c-statistics, while calibration was evaluated by the Hosmer-Lemeshow test. A severity correction model was created using logistics regression analysis. Results: For the APACHE IV, SAPS 3, $MPM_0$ III, and APACHE II systems, the area under the receiver operating characteristic curves was 0.745 for APACHE IV, resulting in the highest discrimination among all four scoring systems. The value was 0.729 for APACHE II, 0.700 for SAP 3, and 0.670 for $MPM_0$ III. All severity scoring systems showed good calibrations: APACHE II (chi-square, 12.540; P=0.129), APACHE IV (chi-square, 6.959; P=0.541), SAPS 3 (chi-square, 9.290; P=0.318), and $MPM_0$ III (chi-square, 11.128; P=0.133). Conclusions: APACHE IV provided the best discrimination and calibration abilities and was useful for quality assessment and predicting mortality in medical ICU patients.

  • Objectives: This study aims to identify the factors associated with colorectal cancer screening behaviors. Methods: The nation-wide representative samples of 2,928 adults aged ${\geq}50$ years for colorectal cancer screening were derived from the fourth Korea National Health and Nutrition Examination Survey (KNHANES IV). This study investigated socio-demographic, health behavioral and contextual factors associated with colorectal cancer screening using descriptive statistics and multivariate logistic regression analysis. Results: In terms of socio-demographic factors, gender, age, marital status, occupation, monthly income, and resident region were significantly different between screening group and non-screening group. Among health behavioral and contextual factors, regular physical checkup, weight control, physical activity, smoking, drinking and having other cancers were significantly different. From the multivariate logistic regression analysis, marital status, education level, regular physical checkup and weight control were associated with colorectal cancer screening behavior. Conclusions: It is necessary to understand the importance of early detection and cancer screening. Appropriate health education and active promotion about the cancer screening should be developed based on the study findings in order to motivate people to have cancer screening. Also, these findings should be reflected in the health policy.
