Purpose: This study was done to explore the relationship between perceived patient safety culture and patient safety management activities among health personnel. Methods: This study was a cross-sectional survey. Participants were 342 health personnel working in two tertiary hospitals. Self-administered questionnaires were used to collect data from a convenience sample of 254 nurses and 88 doctors. Results: Scores on participants' perceived patient safety culture and patient safety management activities were just over the mean. There were significant differences in patient safety management activities by type of occupation, nurses' position, length of service, and work week. Doctors scored perceived patient safety culture and patient safety management activities significantly lower than nurses. In addition, perceived patient safety culture was significantly related to patient safety management activities. Factors which influence participants' patient safety management activities were communication, type of occupation, overall evaluation of patient safety, supervisor/manager, frequency with which events were reported, and nurse's position. Conclusion: Findings provide significant evidence that patient safety management activities are associated with perceived patient safety culture. Therefore, to build a positive safety culture, health personnel, especially doctors and general nurses need to visibly commit to patient safety management activities and be role models to ensure patient safety.

Objective: Falls are defined as contact of the body with the floor after losing balance during activities of daily living. Falls commonly occur among the elderly, and stroke patients in particular are at a high risk of falling. The purpose of this study was to investigate the changes of temporal and spatial gait parameters and gait symmetry according to experience falls in post-stroke patients. Design: Cross-sectional study. Methods: Fifty three patients with stroke were recruited on a voluntary basis from the rehabilitation unit, who currently undergoing physical therapy. All participants were asked to answer questions regarding the frequency of falls in the past 1 year. Fifty-three patients with stroke were allocated 2 groups according to experienced falls: stroke with falls (n=26) during past 1 year and stroke without falls (n=27). The spatial and temporal gait parameters and gait symmetry ratio were measured using GAITRite system. Results: The spatial gait parameters and the temporal gait parameters were significantly different between the stroke with falls group and the stroke without falls group (p<0.05). Furthermore, step length was the only significantly different among symmetry ratio (p<0.05). Conclusions: Experience of falls can lead to impairment of gait ability in stroke patients. This result is expected to be used as a basic data for rehabilitation program development to prevent a fall of post-stroke patients.

This study was conducted to evaluate the effectiveness of team system at university hospitals in Korea. Data were collected from administrative and medical support workers at 4 university hospitals through the self-administered questionnaires and analyzed using frequency analysis, t-test, and oneway ANOVA. The results of this study are as follows. First, teams with higher team management characteristics show higher level of quality of work life and performance effectiveness. Second, teams which consist of members with variety background and skills show higher level of quality of work life and performance effectiveness. Third, team which have the higher autonomy, technology variety, job significance, and feedback show higher team effectiveness. Fourth, team which have team leaders with higher leadership score show higher level of quality of work life and performance effectiveness. Fifth, there are differences in team effectiveness in terms of sicio- demographic variables such as average age, position, and tenure of team members, length of team system, and team size. Sixth, the job autonomy of team members and the leadership of team managers have significant effects on the quality of work life variables. Seventh, the leadership of team leaders, job autonomy of members, and individual contact between team managers and members have significant effects on the team performance variables. In conclusion, in order to increase the effectiveness of team system in university hospitals, it is required to consider the characteristics of team management, diversity of team members, the autonomy of team members, the leadership of team manager, and the socio-demographic factors of team members.

In SIR filter, fringing capacitances and discontinuities yield a distorted frequency response from those expected by design formulas, especially in higher frequencies. In this paper, a procedure is presented in order to compensate for fringing capacitances and step impedance discontinuities by EM simulation for a 5th order SIR filter. This method propose the procedure of tuning the coupling and the length of individual resonator by EM simulation. For the filter composed by the tuned resonators, no further tuning is required. The procedure is experimentally justified by comparing the measured data of the fabricated filter with the simulation results.

The purpose of this study is to examine the effects of job-related characteristics on alcohol consumption among female workers. The Data was collected from a sample of 1,000 female workers by a stratified proportional quota sampling method derived from those who were working in Seoul. Drinking behavior pattern includes total amount of pure alcohol consumed during the last month (AC) measured by graduated quantity-frequency. Job-related characteristics (JRC) were measured by job-related stress, work characteristics, and organizational structure including length of working hours, number of times dining out together with workers per year, number of staff to supervise, employment status, occupational category, and proportion of female workers to male counterpart. Confounding variables include sociodemogrphic and socio-cultural attitudes toward alcohol expectancy, subjective norm of drinking, and gender-role attitude. Hierarchical multiple regression models show that the variability of AC was accounted for by some JRC including number of times dining together and employment status, with confounding variables held constant. However, the relationship between AC and JRC varied across occupational categories. Some implications were discussed in terms of health policy for female workers and further study for female drinking behavior.

The purpose of this study is to investigate the relations between Wives' marital satisfaction and Divorce attitude as a basis building in marital stability . A measurement tools used for this study are marital satisfaction scale, which was adapted and reproducted from Dyadic Adjustment Scale(DAS) developed by Spanier and Divorce attitude Scale, which was developed by researcher refer to preceding study connected with a cause of divorce. The subjects were 354 married women dwelling in Seoul. Statistical methods such as frequency, percentile. mean , standard deviation, one way ANOVA, and Pearson Correlation were used for data analysis. The results of this study are as follows; 1) there is the tendency to high marital satisfaction group rather more than low marital satisfaction group and to permissional attitude group rather more than negative attitude group about divorce attitude. 2) There was difference in marital satisfaction by number of children, wives's educational level, parents marriage happiness. While, there was no difference in marital satisfaction by length of marriage, family income, wives employments status, marriage pattern. 3) There was partially difference in wives' attitude toward divorce by wives educational level, family income. Both there was no difference in wives attitude toward divorce by the other factors. 4) wives' attitude toward divorce correlates with marital satisfaction. The correlation coefficients is 283 significantly of .001 level. The more satisfaction wife feels about her own matrimony. the more negative a attitude she has toward divorce. This menas that attitude toward divorce depends upon their matrimony. 5) The four type of marital stability are as follows; high marital stability type, high subjective unstability type, high objective unstability type, high marital unstability type.

In previous modeling of Helmholtz-type pulse combustion water heater, muffler and the motion of the flapper valve were omitted. In present work, these have been included in modeling for providing more accurate information regarding the thermal and dynamic behavior of the water heater. In addition, a computer simulation based on the modeling was developed. The comparison of computer predictions with available experimental data shows that the simulation is satisfactory in predicting the nature of operating behavior, amplitudes of the pressure oscillations, and the magnitude of the frequency. But the predicted time-averaged axial temperature of the flue gas along the flue tube length is somewhat below the previous experimental results. The temperature pulsation of the combustion chamber and the velocity pulsation of the flue gas were predicted which have never been measured in previous studies. In particular, the latter is of importance for a valid determination of the heat transfer enhancement due to the gas flow pulsation. Heat transfer results in flue tube were presented and discussed. Also the effects on the installation of the muffler were investigated.

The purpose of this study was to investigate the effects of the hair style, and perceiver's generation on the perception of a high schoolgirl's image. A quasi-experimental method by questionnaire was used. The subjects were 253 high schoolgirls and their mothers living in Jinju. The data were analyzed by using frequency, factor analysis, Cronbach's alpha-reliability coefficient, three-way ANOVA, and Duncan's multiple ranges test. The high schoolgirl's image was derived in five dimensions by factor analysis: schoolgirl look, prettiness, individuality, activeness, and cuteness. In the image based on the hair length, it was assessed that the short cut and the bobbed hair styles looked more like school girls. And the short cut and long hair styles were considered as showing individuality. On the other hand, the bobbed hair style was assessed as cuter than styles of other lengths. For the bangs, the short bangs were found to more school-girl look and cuter than the long bangs. The mother group, whose ages were older than that of the other group, evaluated that the stimulative pictures had more school-girl look, individuality, prettiness, activeness and cuteness, compared to how the school girl group evaluated. It was shown that the generation gap produced different opinions about the stimulative pictures. Therefore hair style, bangs style, and difference in generations were found to be the variables affecting perception of high school girl image.

In this paper, we applied mode matching and generalized scattering matrix methods to three plane mode matching method for analyzing T-junctions. We calculated all scattering matrix elements by only three times and considered several incident modes. By proposed analysis method, we could analyze various waveguide discontinuity structures more conveniently and accurately. Using the stepped T-junction, we would be able to reduce the reflection coefficient at an input port and use it over wider band. Simulated and HFSS data of T-junctions are compared, showing good agreement for scattering matrix elements. Considering step numbers, height, length and position, we extracted for optimum dimensions and equivalent circuit parameters.

To determine the frequencies of the genotypes of estrogen metabolising enzyme (CYP17, CYP1A1, CYP1B1, and COMT) and to identify the high-risk genotypes of these metabolic enzymes to breast cancer in Korean, the author has analysed 115 breast cancer patients and corresponding age and sex matched heathy controls using polymerase chain reaction-restiction fragment length polymorphism (PCR-RFLP). A2/A2 genotype in CYP17 polymorphism, m2/m2 genotype in CYP1A1 polymorphism, and Val/Val genotype in CYP1B1 had 0.95, 1.40 and 0.76 relive risks to breast cancer comparing with reference genotypes of each polymorphism, respectively. Among the genotypes of COMT enzyme polymorphism, L/H and L/L genotypes had 0.97 and 1.54 relative risks to breast cancer, respectively. According to the number of high risk genotype, the patients with one or two putative high risk genotypes had 0.95 and 1.94 relative risks to breast cancer, respectively. This study have demonstrated the unique frequency of genotypes of estrogen metabolizing enzyme in Korean healthy women, which will provide the basic data and insights to study the estrogen related conditions in Korean women including breast and endometrial cancers. And it also indicates that the well-known high risk genotypes of estrogen metabolizing enzymes are not significantly associated with the development of breast cancer in Korean women.
