Purpose: This study aims to present practical data available for the effective health management and improvement for the dental technicians by exploring the interrelationships between general characteristics of dental technicians and seven health related habits like drinking, smoking, breakfast, and snacks among the others(alameda 7). Methods: Out of the random selection of the registered dental offices of Dental Technicians Association of Korea, 2,000 working dental technicians were asked to fill out the questionnaire from January 19 to April 30, 2009. We collected the 1,502 sheets of the questionnaire and took frequency analysis, crosstabulation, t-test, and analysis of variance using SPSS Win 12.0 program. Results: Among the seven health related habits, 54.9% of the subject answered 'never do exercise' in the question of exercise habits, which is the most problematic of all. Hours of sleep and BMI were found to be quite low. Of the general characteristics, sex proved statistically significant to all the seven habits(p<.001). Marital status, job title, and health check-up showed statistical significance in six items among the seven habits. Age, monthly income, job position showed statistical meanings in five items among the seven habits. The frequency of break showed statistical significance in four items among the seven habits. Working environment showed statistical significance only in the item of hours of sleep among the seven habits(p<.05). Conclusion: This study proved that it is vital to educate the dental technicians to learn the right habits for enhancing their health and quality of life and motivate them to practice those habits.

This study investigated the background of the intellectual ability that consists of family environment, intellectual priority, career aims, intellectual extracurricular activities of the students who were selected for the Science Gifted Education Center. We performed a survey and analysis of the students at the Science Gifted Education Center in order to explore their learning attitudes and intellectual ability, as well as the elements that represent their attitudes. As a result of the study, I found that the students in the Science Gifted Education Center generally had good economic and family backgrounds that showed no significant hardship in supporting the students. The families were also highly educated intellectually. In case the talented students in Science desired to be pure scientists, they liked the Science subjects and enjoyed reading science books. It was mostly the male students that took part. As for the attitude toward intellectual ability, they expected to improve their abilities as they gained knowledge and increased their intelligence through learning, although they didn't confide with us on their intelligence quotients. There were four factors for these attitudes. They include the high expectation of them by others; confidence and ease of mind regarding the assignment; the expectation for improvement in intelligence and ability through learning; and, confidence in intelligence and positive attitude in the participation situatio

Ubiquitous is a Latin-derived word meaning "to exist at any time and place" like water or air. In computing, the word "ubiquitous" indicates an environment in which users have access to networks without any limitation regarding computer networks or places. Important issues in building Ubiquitous Korea (U-Korea) are the social problems appearing with a rapid increase in the old age population. Nowadays, with the rise of the nuclear family, the increase in the number of elderly people living alone, and the change in the status of women, both wives and husbands are employed outside the home, and the relatives who would be responsible for supporting the elderly sometimes are on long or short business trips, and it happens that old people can't be looked after. Therefore the government developed a wireless paging system for the sick, disabled, old and weak so that when an emergency happens, by just simply dialing 119, an emergency aid center could take prompt action. However, the present wireless paging systems composing the under-layer of the emergency aid information system have some problems, such as, a lack of reliability, problems among terminals, mobile transmitters and receiving terminals, the users' refusal to admit the need for the system and poor operational skills, administrators' perfunctory management and checks, etc. On account of these problems, the system efficiency has degraded and therefore a system upgrade is necessary. In this paper, we attempt to evaluate the newly implemented SAFE119 system, a new wireless paging system seeking to correct the problems of the current system.

Samples of Badwater greenstones from the Crystal Falls terrane in northeastern Wisconsin have been analyzed for major, trace and rare earth elements. Geochemical characteristics of the rocks provide clues to the petrologic character and paleotectonic environment of basaltic magma generation. They have chemical composition typical of continental tholeiites. The low Mg values and abundances of Ni and Cr indicate that the lavas were extensively fractionated prior to extrusion. The variations of incompatible elements suggest that the rocks were affected by interaction with crustal rocks. The samples least affected by contamination have trace element compositions similar to those of T-type mid-ocean ridge basalts. The parent was modified by crustal contamination process and this process shifted the rock compositions to that of continental tholeiites as the rock evolved. Interpretations of the chemical characteristics of the rocks, based on modem analogs, favor their emplacement in an extensional tectonic regime.

Purpose: Child Health nurse practitioners (CHNPs) in Korea have important roles in disease management and health promotion for children and adolescents. Yet, practices of CHNPs licensed and employed in hospitals have not been adequately identified. Thus, in this study the scope of practice by CHNPs and job satisfaction and stress were investigated and compared according to the CHNPs' position in the working place. Methods: A descriptive cross-sectional survey design was used. All 53 licensed CHNPs participated in the mail survey which included a 71-item questionnaire on job performance and job satisfaction and a job contents questionnaire. Descriptive statistics, ${\chi}^2$ test, independent t-test and Mann-Whitney U test were used to compare CHNPs employed as nurse practitioner (NP) and CHNPs employed as staff nurses. Results: Compared to CHNPs employed as staff nurses, CHNPs employed as NPs more frequently provided education, environment management, coordination and research in their practice areas. No significant difference was found in job satisfaction between the two groups except for the administration and income subdomains. Only the physical exertion subdomain in job stress was stressful to CHNP employed as staff nurse. Conclusions: Job performance of CHNPs in Korea needs to be revised to include more practical practice in education, coordination, and research related areas.

Recent observations by Hinode show weakly-attenuated coronal loop oscillations in the presence of background flow (Ofman & Wang 2008, A&A, 482, L9). We study the vertical kink oscillations in solar coronal loops, considering field aligned flows inside the loops as well as surrounding the loops environment. The two dimensional numerical model of straight slab is used to explore the excitation and attenuation of the impulsively triggered fast magnetosonic standing kink waves. A full set of time dependent ideal magnetohydrodynamics equations is solved numerically taking into account the value of flow of the order of observed flows detected by SOT/Hinode. We find that relaxing the assumption of the limited flows within the loops enhances the damping rate of the fundamental mode of the standing kink waves by 2 - 3 % as compared to flow pattern which is basically localized within the loops. We further notice that extending the flow pattern beyond the loop thickness also enhances the strength of the shock associated with slow magnetoacoustic waves, recognized as an addition feature detected in the numerical simulation. The wider out-flow pattern destroys the oscillation patterns early as compared to narrower flow pattern, in other words we can say that it affects the durability of the oscillation. However, for the typical coronal loops parameters we find that the observed durability periods of the SOT/Hinode observation can be achieved with an out-flow Gaussian patterns for which half-width is not greater than factor 2.0 of the loop-half-width. explain a possible relation between electric current structure and sigmoid observed in a preflare phase.

Objectives: The purpose of this study was to investigate nail hygiene behaviors and to identify the relationship between hand hygiene beliefs and nail hygiene behaviors among dental hygienists, dental's aide and dental coordinator in South Korea. Methods: The subjects were 291 dental workers including dental hygienists, dental assistant and dental coordinator working full-time at dental clinics, dental hospitals, general dental hospitals and dental university hospitals in Seoul, Incheon, and Gyeonggi-do. The questionnaire consisted of a total 35 items, including 4 items on general characteristics, 25 items on hand hygiene, 2 items on "nail art" experience, and 4 items on nail hygiene behaviors. The collected data were analyzed using an independent t-test, one-way ANOVA, chi-square test, correlation analysis, and multiple linear regression analysis, where ${\alpha}<0.05$ was considered statistically significant. Results: The scores of behavioral beliefs, normative beliefs, control beliefs and nail hygiene behaviors were $5.15{\pm}0.58$, $5.26{\pm}0.81$, $3.69{\pm}0.96$ and $5.03{\pm}0.98$, respectively. Statistically significant relationships were detected in terms of participants' clinical experiences with respect to behavioral and normative beliefs (p<0.05 for all three belief categories). Participants working in general dental hospitals and dental university hospitals demonstrated the highest scores for behavioral, normative and control beliefs (p<0.05). Participants working in dental clinics reported the highest "nail art" experience rates in the last two years (45.5%) and at the time of the survey (15.7%; p<0.05). Nail hygiene behaviors were more likely to be observed in individuals with stronger behavioral and stronger normative beliefs (p<0.05). Conclusions: More specific infection control guidelines for "nail art" among dental workers should be established and promoted, so that both patients and dental workers can interact in a safe environment.

This research paper delved into the availability and utilization of library portal services for research in university libraries in Nigeria. Two research questions and two null hypotheses were formulated to guide the study. A structured questionnaire was used for data collection. The study was carried out in Nnamdi Azikiwe Library, University of Nigeria Nsukka (UNN) and Felix Aghagbo Nwako Library, Nnamdi Azikiwe University Library (UNIZIK), Awka. A total of 70 professionals (librarians and system analysts) in these libraries supplied data for the study. Data collected was analyzed using mean and standard deviation. These were used to answer the research questions while the null hypotheses were tested using t-test statistic at 0.05 level of significance and 68 degree of freedom. Major findings showed that portal services available in the library showed that the areas of availability of library portal services in Nnamdi Azikiwe Library, U.N.N. includes Agriculture, Health Sciences, Engineering, Environmental Sciences and information about institution, Social Sciences, Arts and Humanities, Natural Sciences. In Festus Aghagbo Nwako Library, Awka, the areas of Portal Library Services include Career Development, Federal Government Programs, Environmental Sciences, Biological Sciences, Social Sciences, Arts and Humanities, Engineering, and Health Sciences. Findings on extent of utilization of portal services available in the libraries indicated that portal services are utilized to a low extent in the university libraries. Furthermore, librarians did not significantly differ in their opinions on the availability of library portal services and on the extent of utilization of library portal services in the libraries under study. It is therefore recommended that provisions should be made by the universities and library management to provide and update required portal services in addition to creating enabling environment for enhanced access and utilization of these services. The governments must make an effort to provide funds for policy implementation, necessary technology training for librarians and users, and develop general information infrastructure.

This exploratory study evaluated various factors influencing the level of nursing self-confidence in the performance of core nursing skills among nursing students. This study surveyed 131 senior nursing students in U city with a structured self-report questionnaire analyzed by SPSS 23.0 software. The average perception scores for importance, problem-solving process, and self-confidence in the performance of core nursing skills were 4.73, 3.57, and 3.90, respectively. The most significant factors affecting self-confidence in the performance of core nursing skills included problem-solving process (β=.33, p=.001) and nursing satisfaction (β=.27, p=.019). These variables explained 15% of the total variance in self-confidence in the performance of core nursing skills. Based on the results of this study, it is necessary to perform research in order to improve the self-confidence of performing core basic nursing skills among nursing students, and the department of nursing defines students' problems by suggesting changes in the practice environment and various nursing situations to improve interpersonal skills. Therefore, it is necessary to develop a curriculum that can be solved and a program to increase nursing satisfaction.

In northern Gohung granitic gneiss, porphyroblastic gneiss and migmatitic gneiss are widely distributed. Gneisses were plotted in granodiorite domain on an lUGS silica-alkali diagram. The amounts of trace elements (Li, Zn, Sc, Sr, Ni, V Y etc.) vs. $SiO_2$, somewhat decreased. Plagioclase showed a wide compositional range ($An_{32-48}$). $X_{alm}$ and $X_{sps}$ were higher in garnet rim and $X_{pyp}$ in garnet core. The rocks in the study area were formed from S and I-type magmas which generated from syn-collision and the late to post-orogenic tectonic environment. Metamorphic P-T conditions u·ere low to medium pressure, high temperature (803-913$^{\circ}C$, 6.1-7.3 kb) and overprinted by retrograde metamorphism (570-726$^{\circ}C$, 2.2-5.1 kb) and chloritization.
