  • The purpose of this study was to define whether NSILQ is useful for the nursing student in supporting women labor room(Nursing Support in Labor Questionnaire). The retrospective study was conducted to identify the helpfulness of nursing student support behaviors as perceived by women in Labor. This sample of 152 women completed two data collection instruments : a demographic & obstetric questionnaire(12) and NSILQ(20). The data were analyzed by Cronbach alpha, descriptive statistics, t-test, ANOVA with SAS program. The result of this study are as follows. 1. All of NSILQ nursing behaviors were perceived as helpful in this study. The total mean of perceived score was $3.4{\pm}0.90$. 2. According to the type of nursing support, the mean of Affect(AT) care was $3.48{\pm}0.79$, the mean of Aid(AD) care was $3.37{\pm}0.82$, the mean of Affirmation(AM) care was $3.35{\pm}0.90$. Among the type of care, the AD care was 52.2%, and the most helpful one. 3. The significant characters of nursing support are antenatal care numbers and husband with or not in labor process. In the group of score of nursing support, the number of antenatal care was low(F=3.90, P=0.02). The score of the group husbands in labor process was higher.(T=4.55, P=0.001). 4. The significant characters of influencing on nursing support required are the person who helped and whether women has job or not. 5. The highest numbers of wanting nursing support are Aid cares(74.3%). The care the women wanted mostly was Aid cares (74.3%; pain control in labor(56.6%), physical comfort(6.6%), coach in labor(3.9%), explain of dilatation(1.3%) in rank.

  • This study examines the relationship between financial behavior, financial literacy, self-efficacy, and self-coping among emerging adults. The study population is 790 respondents from 11 Credit Counselling and Debt Management (CCDM). Statistical Package for Social Science (SPSS) was used to analyze Pearson Correlation and Multiple regression. It was used to determine the relationships and recognize determinants of emerging adults' financial behavior respectively. In this study, financial literacy, self-efficacy, self-coping, and financial behavior variables were entered into the regression. A total of 790 respondents aged 40 and below were selected. An independent sample t-test was administered to compare the financial behavior scores for females and males. The results reveal that there was significant difference in the mean of financial behavior scores for females (M = 87.20, SD = 18.00) and males (M = 89.70, SD = 16.80; t (765) = 2.010, p = 0.045, two-tailed). The multiple regression results indicate that the model explained 13.4% of the variance in financial behavior, which is predicted significantly by the model (F = 38.361, p = 0.000). This study will be beneficial to policymakers to improve living conditions and to promote good financial behavior, financial literacy, self-efficacy as well as self-coping especially for emerging adults in Malaysia.

  • Obesity in children is a major concern of public health. This study was performed to illuminate its effect on weight control program and the associated factors of obesity-related habits and obesity index in primary school obese children. Weight control program consisted of behavioral modification, nutrition education and exercise during 17 weeks. The sample consisted of treatment group(n=42) and control group(n=41). There was no statistical difference between the two groups in obesity index, socioeconomic status and grade. To assess the effects of weight control program, the subjects were given pre-test and post-test such as the measurement of anthropometric values and self-reporting questionnaire. This result of this study were as follows; 1. After weight control program was applied, there was a significant decrease in obesity index among the treatment group. Obesity-related habits score of the treatment group increased significantly, While there was not much difference between the pre-test and the post-test among the control group. But exercise habit didn't increase significantly in the both groups. 2. Correlation between obesity-related habits and obesity index were not evident. 3. After application of weight control program, the factors associated with change of eating habit were children's past experience of weight control, motivational change toward weight control program and friends' support for treatment group. The factors associated with change of exercise habit were post-test motivation score and friends' support. Motivational change toward weight control and pre-test self-efficacy of exercise behavior were counter-related to exercise habit. For change of other obesity-related habits, initial obesity index, motivational change, post-test self-efficacy score of exercise behavior and paternal educational status were closely associated. But post-test self-efficacy score of eating behavior was unrelated. 4. Only the factor of experience of weight control was associated with change of obesity index. 5. For the both groups, the factors associated with change of eating habits were post-test self-efficacy of eating behavior and family's support. The factors associated with change of exercise behavior were self-efficacy changes of exercise behavior and friends' support. The factors associated with change of other obesity-related habits were self-efficacy change of eating behavior. Initial obesity index was associated with change of obesity index. 6. The rate of dropouts from weight control program was 28.6% (12/42) in treatment group. Initial obesity index, other obesity-related habits except eating exercise habits, friend's support were associated with dropout. In conclusion, these results indicated that weight control program in primary school settings was effective. Direct exercise regimen and practice was demanded. In addition to the program itself, much of the success is dependent on the degree of motivation of the children involved and support provided by their parents and friends. Further study need to be performed under the condition that the weight control progrom is applied for a longer period.

  • Statement of problem. Unreasonable distal cantilevered implant-supported prosthesis can mask functional problems of reconstruction temporarily, but it can cause serious strain and stress around its supported implant and surrounding alveolar bone. Purpose. The purpose of this study was to evaluate strain of implants supporting distal cantilevered fixed prosthesis with two different cantilevered length under distal cantilevered static load. Material and methods. A partially edentulous mandibular test model was fabricated with auto-polymerizing resin (POLYUROCK; Metalor technologies, Stuttgart, Swiss) and artificial denture teeth (Endura; Shofu inc., Kyoto, Japan). Two implants-supported 5-unit screw-retained cantilevered fixed prosthesis was made using standard methods with Type III gold alloy (Harmony C&B55; Ivoclar-vivadent, Liechtenstein, Germany) for superstructure and reinforced hard resin (Tescera; Ivoclar-vivadent, Liechtenstein, Germany) for occlusal material. Two strain gauges (KFG-1-120-C1-11L1M2R; KYOWA electronic instruments, Tokyo, Japan) were then attached to the mesial and the distal surface of each standard abutment with adhesive (M-bond 200; Tokuyama, Tokyo, Japan). Total four strain gauges were attached to test model and connected to dynamic signal conditioning strain amplifier (CTA1000; Curiotech inc., Paju, Korea). The stepped $20{\sim}100$ N in 25 N increments, cantilevered static load 8mm apart (Group I) or 16mm apart (Group II), were applied using digital push-pull gauge (Push-Pull Scale & Digital Force Gauge, Axis inc., Seoul, Korea). Each step was performed ten times and every strain signal was monitored and recorded. Results. In case of Group I, the strain values were surveyed by $80.7{\sim}353.8{\mu}m$ in Ch1, $7.5{\sim}47.9{\mu}m/m$ in Ch2, $45.7{\sim}278.6{\mu}m/m$ in Ch3 and $-212.2{\sim}718.7{\mu}m/m$ in Ch4 depending on increasing cantilevered static load. On the other hand, the strain values of Group II were surveyed by $149.9{\sim}612.8{\mu}m/m$ in Ch1, $26.0{\sim}168.5{\mu}m/m$ in Ch2, $114.3{\sim}632.3{\mu}m/m$ in Ch3, and $-323.2{\sim}-894.7{\mu}m/m$ in Ch4. Conclusion. A comparative statistical analysis using paired sample t-test about Group I Vs Group II under distal cantilevered load shows that there are statistical significant differences for all 4 channels (P<0.05).

  • Recent research indicates that the new mothers want to learn about childrearing, and have burden in care of infants. Also it indicates that the new mothers say the lack of confidence and knowledge about infant care. This study was a prospective longitudinal reseach developing parent role education program and evaluating the effectiveness of this program for mother-infant interaction, childrearing environment and infant development. Longitudinal quasi-experimental design was used. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their mothers. The sample consisted of 19 mother-infant dyads for intervention group and 18 dyads for control group. Data were collected from March 15th to December 14th in 1999. For the intervention group received programmed education that was consisted of discharge education, telephone counselling, and home visiting for maternal education. The data were analyzed using chi-square test and t-test to test the equivalence of two groups, and the effectiveness of intervention program. This study was focused on the results of six months time point. The results were as follows: 1. There was significant difference in the mean score of mother-infant interaction(NCAST) between two groups. Intervention group showed higher scores in the subscales of sensitivity to cues, cognitive growth fostering, and caregiver total. 2. There was no significant difference in the mean score of child rearing environment (HOME) between two groups of six-month-infants. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of opportunities for variety in daily stimulation, maternal involvement with child, and emotional, verbal response. 3. Six-month-infants of the intervention group showed significantly higher GQ in the Griffiths mental development scale. In conclusion, the maternal education program was effective in promoting the mother-infant interaction, organizing the childrearing environment, and fostering the infant development. These results were very meaningful that we found parent role education necessary for normal infants' mothers, and nurses can make a great contribution in promoting health of infants and mothers.
