Purpose: The purpose of this study was to measure empowerment and to identify factors influencing empowerment. Method: Subjects included 767 clients registered with the customized home visiting health services in Daegu. Data collection was performed from June 3 to July 30, 2011. Descriptive statistics, ${\chi}^2$ test, ANOVA, and stepwise multiple regression were used in this study. Results: The mean score for total empowerment was 3.01(${\pm}0.28$). In subscales of total empowerment, the score for individual empowerment was 2.97(${\pm}0.36$), the score for interpersonal relationship empowerment was 3.09(${\pm}0.34$), and the score for political-social empowerment was 2.96(${\pm}0.48$). Job, education, economic status, living arrangement, and client classification were significant factors related to total empowerment in these clients. Job, education, economic status, types of health insurance, living arrangement, age, and client classification were significant factors related to individual empowerment, interpersonal relationship empowerment and political-social empowerment. 4.4 percent of the variance in total empowerment can be explained by education and living arrangement (Cum $R^2=0.044$, F=13.207, p<.001). Individual empowerment, interpersonal relationship empowerment, and political-social empowerment can be explained by education, job, economic status, and living arrangement. Conclusion: An empowerment intervention that includes general characteristics of clients is essential to improving empowerment of customized home visiting health care services beneficiaries.

The present study was performed to observe the effects of cations on resting membrane potential and pump activity in the unfertilized eggs of ICR strain mice. After an induction of superovulation, the fresh eggs with zona pellucida were collected and the membrane potentials were recorded. Recordings of membrane potential in this study was obtained from the physiological conditions ($37^{\circ}C$ and 4mM Ca in standard solution), differently from the another reports with unphysiological conditions (room temprature and high Ca in standard solution) for a stable and long-lasting observations. Presented data was obtained within 6 hours after collection from the oviduct. The results observed are as follows, 1) Resting potential of the unfertilized eggs was $-25.8{\pm}3.8mV$ $(Mean{\pm}Se,\;n=31)$. 2) As the K ion concentration was increased, resting membrane potential was depolarized but showed hyperpolarization with $K^{+}$ below 25mM. 3) Alteration of the resting membrane potential for the changes of $Na^{+}$ concentration were hardly observed, while resting potential was hyperpolarized as $Ca^{2+}$ concentration was increased. 4) Pump activity as transient or prolonged hyperpolarization was $-2.29{\pm}0.75mV$ $(Mean{\pm}Se,\;n=16)$, the hyperpolarization was increased in both amplitude and duration under the 10mM $Ca^{2+}$ solution. 5) Hyperpolarization due to pump activity was decreased or disappeared by $5{\times}10^{-5}\;M$ ouabain treatment and could not be observed under the both Na-free and Ca-free solutions. 6) Above results are likely to suggest that the resting potential of the mouse unfertilized eggs is affected to mainly by Ca-dependent K conductance and Na-Ca exchange mechanism and that there is pump activity coupling between $K{+}$, $Na^{+}$ and $Ca^{2+}$.

Background: The prevalence of prostate cancer is considered high in many countries, and screening tests are very important in order to detect prostate cancer in its early stages; however false positivity with these screening tests means that a lot of patients undergo unnecessary biopsy, which is an invasive procedure, for the confirmatory test. The purpose of this study was to estimate the frequency of unnecessary biopsy cases in patients referred for prostate biopsy in one of the most important and overload cancer centers in Syria. Materials and Methods: Retrospective data for a period of four years between January 2009 and December 2012 were collected in Al-Bayrouni University Medical hospital in Damascus, Syria. The patients from whom data were collected were referred to our histopathological department because of elevated prostate specific antigen (PSA) serum or an abnormal digital rectal examination (DRE). All patients underwent prostatic TRUS-guided biopsies. Diagnosis of prostate cancer (PCa) or benign prostatic hyperplasia (BPH) was based on histopathological examination and prostate cancers cases were graded and scored according to the Gleason score system. Results: For the 406 patients referred to biopsy, the $mean{\pm}SD$ age was $58.4{\pm}23.3$ years. The $mean{\pm}SD$ PSA level was $49.2{\pm}21.5ng/ml$. Of the total we found 237 patients diagnosed with PCa (58. 4%), 166 patients with BPH (40.9%) and 3 cases were unable to be diagnosed (0.7%) because of biopsy collection errors. Conclusions: Our study shows that a high percentage of patients are undergoing unnecessary biopsy, which suggests that the performed screening tests had a high level of false positive and may need re-evaluation.

Background: This study was conducted as a descriptive-correlational exercise with the aim of determining the effect of student perceptions of social skills on their pro and con perceptions of smoking. Materials and Methods: The study sample comprised 106 students at $6^{th}$, $7^{th}$ and $8^{th}$ grades in three primary schools. The data were collected through socio-demographic data collection form, Social Skill Perception Form and Child Decisional Balance Scale. Data were evaluated by percentage calculation, Student t test and correlation analysis. Results: While the point average of pro perception of smoking of the students with a high point average of social skill perception, was $8.6{\pm}3.1$, in those with a low social skill perception point average it was $10.7{\pm}4.2$, the difference being significant(p=0.012). The respective point averages of con perceptions were $26.8{\pm}3.7$ and $23.5{\pm}3.3$, again significant (p=0.000). While a positive medium level (r=0.410) relationship was determined between the point average of social skill perception and con perception of smoking, a negative low level (r=0.281) relationship was determined with the pro perception of smoking. Conclusions: As the social skill perception point average increases, children's con perceptions of smoking increase and their pro perceptions decrease.

The collection of TSP and $PM_{2.5}$ aerosols has been made at the Gosan Site of Jeju Island during 2008-2011, and their ionic and elemental species were analyzed, in order to examine the seasonal variation and characteristics of aerosol compositions. The anthropogenic components ($NH_4{^+}$, $nss-SO_4{^{2-}}$, $NO_3{^-}$, S, Zn, Pb) and the soil components ($nss-Ca^{2+}$, Al, Fe, Ca) showed high concentrations in spring as the prevailing westerly wind, but the concentrations of the sea-salt components ($Na^+$, $Cl^-$) were high in winter. In TSP, the neutralization by $NH_3$ increased in summer, but the neutralization by $CaCO_3$ increased in spring and fall seasons. The organic acids ($HCOO^-$, $CH_3COO^-$) contributed to the acidification of the aerosols by only 5.0%, so the acidification could be mostly contributed by the inorganic acids ($SO_4{^{2-}}$, $NO_3{^-}$). From the examination of the source origins by factor analysis, the compositions of TSP were influenced by the order of soil > anthropogenic > marine, on the other hand, those of $PM_{2.5}$ were by the order of anthropogenic > marine > soil. The backward trajectory analyses showed that the concentrations of $NH_4{^+}$, $nss-SO_4{^{2-}}$, $NO_3{^-}$ and $nss-Ca^{2+}$ increased highly when the air masses had moved from China continent into Gosan area of Jeju Island.
