  • A pulsed Nd:YAG laser is used widely for materials processing and medical instrument. It's very important to control the laser energy density in those fields using a pulsed Nd:YAG laser. A pulse repetition rate and a pulse width are regarded as the most dominant factors to control the energy density of laser beam. In this paper, the alternating charge and discharge system was designed to adjust a pulse repetition rate This system is controlled by microprocessor and allows to replace an expensive condenser for high frequency to cheap one for low frequency. In addition, The microcontroller monitors the flow of cooling water, short circuit. and miss firing and so on. We designed Nd:YAG laser firmware with smart microcontroller, and want to explain general matters about the firmware from now.

  • Background: Depression is common in breast cancer patients. The aim of this paper was to make a systematic review of its prevalence and associated factors oin breast cancer survivors. Materials and Methods: An extensive systematic electronic review (PUBMED, CINAHL, PsyINFO and Ovid) and handsearch were carried out to retrieve published articles up to November 2012, using Depression OR Dysthymia AND (Cancer OR Tumor OR Neoplasms as the keywords. Information about the design of the studies, measuring scale, characteristics of the participants, prevalence of depression and its associated factors from the included studies were extracted and summarized. Results: We identified 32 eligible studies that recruited 10,826 breast cancer survivors. Most were cross-sectional or prospective designed. The most frequent instrument used to screen depression was the Center for Epidemiological Studies for Depression (CES-D, n=11 studies) followed by the Beck Depression Inventory (BDI, n=6 studies) and the Hospital Anxiety and Depression Scale (HADS, n=6 studies). CES-D returned about similar prevalence of depression (median=22%, range=13-56%) with BDI (median=22%, range=17-48%) but higher than HADS (median=10%, range=1-22%). Depression was associated with several socio-demographic variables, cancer-related factors, treatment-related factors, subject psychological factors, lifestyle factors, social support and quality of life. Conclusions: Breast cancer survivors are at risk for depression so that detection of associated factors is important in clinical practice.

  • This study was conducted using a descriptive correlational survey design to identify how patients with chronic low-back pain perceived family function and to examine the relationship between family function and depression. The participants of the study were 116 patients with chronic low-back pain patient who were having follow-up treatment in a local pain clinic, located in Daegu. A structured questionnaire was filled out participants themselves and the structured interview was given during January and February, 2000. The data collection instrument were FACE II-Korean version and Beck's Depression Inventory(1983). The data collected were analysed using mean, standard deviation(SD), t-test, F-test, Duncan test and Pearson correlation coefficient, done with SAS. The results are as follows; 1. The mean of the respondents' perceived family function was 3.47, with emotional bonding at 3.61, acceptability and sharing at 3.61, participation at 3.23, negotiation and satisfaction at 3.24 and responsibility and expectation at 3.76. 2. The mean of the respondents' perceived depression was $17.53{\pm}8.76$. 3. There was significantly negative correlation between family function and depression(r=-0.4817, p=.0001). 4. Research variables included demographic characteristics and showed that subjects who were aged 65 years or older showed significantly lower scores in patient's perceived family function than those who were aged 45 years or below(p=.0502). Perceived family function of females respondents were significantly lower than males(p=.0026). The illiterate showed significantly lower scores than other groups(p=.0001). Respondents with spouse and extended family tended to show significantly higher scores than those who were living with spouse only or by themselves alone(p=.0091). Those who had higher income showed significantly higher scores than in the lower income group(p=.0001). 5. For family function regarding pain characteristics, those who reported severe pain-related daily activity impediments showed significantly lower scores in family function than others with less pain(p=.0357).

  • Background: The Work Ability Index (WAI) is an instrument that measures work ability. The wide dispersion of the WAI internationally has led to its adaptation for use in different countries. This study aimed to evaluate the psychometric properties of the Spanish version of the WAI. Methods: A methodological design was used over an opportunistic sample of 233 workers in the aeronautical industry in Spain. Reliability was evaluated through internal consistency. Factorial validity, known groups, and convergent validity were tested. Results: The Cronbach's alpha and item-total correlation indicated an adequate internal consistency. The confirmatory factor analysis, performed to evaluate the factorial validity, found adequate fit indices for a two-factor solution with a high correlation between the factors. Factor 1, "Subjectively estimated work ability and resources", was composed of 3 subscales and factor 2, "Ill-health-related", of 2 subscales. Subscales 4 and 6 had loading in both factors. Workers under 45 years of age obtained higher significant scores than older ones. Convergent validity was also evidenced since WAI was highly correlated with self-assessment of health status. Conclusions: The Spanish version of the WAI has shown evidence of reliability and validity in this study, supporting its use in individual and collective health surveillance by occupational health professionals. The factorial solution that was found has previously been reported in another international context. However, further research is needed to resolve the discrepancies detected in the role of some subscales between other national and international studies.

  • Purpose : This study set out to compare the educational effects of a video self-instruction program for child CPR education on childcare teachers by applying the 2006 KACPR Guideline. By adopting the nonequivalent control group posttest quasi-experimental design, the study examined the educational effects on a group that did not receive instructions from the instructor, another group that received his instructions, and the other group that received an extra three-minute practice training session in addition to instructions. Methods : Data were gathered from August 6 to 18, 2008. As for research tools, the Knowledge Instrument of CPR by Connolly (2006) was used along with the National Practice Test Protocol for C1ass 1 Emergency Medical Technicians (2007) and Common Protocol for CPR (2006) to examine the performance of child CPR. By shooting the guide screen of $Resusci^{(R)}$ Junior CPR Manikin of Leardal with a video camera and using the Skill Guide Checklist of the Common Protocol for CPR (2006), the subjects' technical accuracy of chi1d CPR was evaluated. There were three subject groups: 29 childcare teachers randomly assigned to received the video self-instruction program training for chi1d CPR and no instructions from the instructor made up the control group; 22 childcare teachers randomly assigned to received the program training and instructions from the instructor made up experiment group I; 23 childcare teachers randomly assigned to received an extra three-minute practice training session in addition to the program training and the instructions made up experiment group II. The gathered data were analyzed with SPSS/PC+ (Version 14.0) in frequency, percentage, $X^2$-test, ANOVA, Scheffe test. Results : 1) There were no statistically significant differences (F=1.030, p=.362) among the groups in terms of knowledge scores after the child CPR education. 2) There were statistically significant differences (F=13.625, p=.000) among the groups in terms of performance abilities after the child CPR education. 3) There were no statistically significant differences (F=1.610, p=.207) among the groups in terms of technical accuracy of mouth-to-mouth resuscitation after the child CPR education 4) There were no statistically significant differences (F=1.484, p=.234) among the groups in terms of technical accuracy of chest compression after the child CPR education. Conclusion : The results indicate that childcare teachers can improve their performance abilities in child CPR when the instructors are active with their instructions and extra practice hours are secured through a VSI program. It's also needed to provide education with increasing concentration ratio about the items of lower knowledge points in order to help the teachers learn the accurate theory of child CPR. And there should be VSI programs of diverse conditions to increase the effects of child CPR training among childcare teachers.

One quaxi-experimental, nonequvalent control group post-test design was used to evaluate prevention of phlebitis between a control group and an experimental group. The data for the control group were collected from 100 hospitalized patients from July 1 to November 30, 1999. The data for the experimental group were collected from 100 hospitalized patients from December 1, 1999 to March 5, 2000. The control group used paper tape on the IV site and the experimental group used a sterile gauze dressing which was changed every 24 hours. Two sets of instruments were used for this study. First, instrument developed Weinstein(1993) and modified by the researcher was used for judging phlebitis. The second, instrument developed Park(1996) was used for assessment records concerning the phlebitis which developed. Catheter sites were inspected on a daily basis by unit nurses and development of phlebitis was grade and documented. Data were analyzed using $x^2-test$ and stepwise regression The results are summarized as follows : 1. The incidence of phlebitis according to the duration of catheter insertion decreased in the experimental group($x^2=3.56$, p<.05). 2. The incidence of phlebitis according to the duration of catheter insertion decreased in the experimental group($x^2=28.79$, P<.0001). 3. No significant difference was found between the experimental and control groups in the severity of phlebitis. 4. A statistically significant difference between the two groups was found in the incidence of phlebitis according to the location of the insertion site. 5. No statistically significant difference between two groups was found in the incidence of phlebitis by age 6. A statistically significant difference between two groups was found in the incidence of phlebitis by sex($x^2=3.88$, p<.05) 7. Further study revealed that the duration of catheter and sex were predictors of occurrence of the phlebitis, explaining 38.2%, 14.2% of the total variance respectively. In conclusion, the aseptic dressing method is recommended to be prevent infusion phlebitis.
