Purpose: This study aimed to develop and examine the validity and reliability of a self-efficacy scale for preventive health management related to premature labor (PHMSE-PL) for women of childbearing age. Methods: Instrument development and validation were undertaken in three steps: conceptualization through a literature review and in-depth interviews, item generation and evaluation of content validity, and evaluation of construct validity and reliability. The content validity, factorial structure validity, and internal consistency reliability of the PHMSE-PL were evaluated, and cognitive interviewing was undertaken. Data were analyzed using confirmatory factor analyses, Cronbach's α, and 95% confidence intervals (CIs). Results: The content validity was assessed by experts and was strengthened through cognitive interviews with women of childbearing age. The PHMSE-PL comprised 34 items across five factors. The construct validity of the PHMSE-PL was supported. Cronbach's α for the total scale was .97 (95% CI=.96-.97). Conclusion: An evaluation of the psychometric properties of the PHMSE-PL scale found it to be a valid and reliable tool for women of childbearing age. The scale appears to be useful for women of childbearing age to self-assess their preventive health management self-efficacy related to premature labor and for health professionals to evaluate and promote women's preventive health management.

The purpose of this study is to provide total data of real body-type and self-evaluation about it. The subjects were 614 middle-aged women between 35 and 59 years old. Data were collected through measurement and a questionnaire survey on self-evaluation. The results of self-evaluation of body are as follows; 1. As the result of the recognition degree analysis, people consider themselves thicker, shorter or smaller than what they really we, regardless of ages and types. In addition, the women of younger group rather than the women of older group consider themselves bigger/thicker and shorter than what they really are. They think that the items of waist girth, abdominal girth, hip girth, upper arm girth. and thigh girth are thicker than the other items, however, among girth items the size of bust girth is smaller than the other items. The women of the late middle-aged group consider their somatotype thicker/bigger and shorter than the women of the early middle-aged group do. 2. As the result of body cathexis for each part, women in general rum out themselves not to be satisfied with their body parts, regardless of ages and types. Particularly, they are not satisfied with abdominal girth, weight, hip girth. According to the age bracket, the women in the older group are more satisfied than the women of younger group in terms of their body. According to somatotype, women in tall and slim groups are more satisfied with their body. The women of the early middle-aged group turn out not to be satisfied with girth items while the women of the late middle-aged group are not satisfied with length items.

In this paper, we are dealing with the problems of performance evaluation of Differentiated Services(DiffServ) networks. For successful performance evaluation, the ability to accurately represent "real" traffic on the network by suitable traffic models is an essential ingredient. Many research results on the nature of real traffic measurements demonstrated LRD(long-range dependence) property for the Internet traffic including Web, TELNET, and P2P traffic. The LRD can be effectively represented by self-similarity. In this paper, we design and implement self-similar traffic generator using the aggregated On/Off source model, based on the analysis of the On-Off source model, FFT-FGN(Fast Fourier Transform-Fractional Gaussian Noise) model, and RMD(Random Midpoint Displacement) model. We confirmed the self-similarity of our generated traffic by checking the packet inter-arrival time of TCPdump data. Further we applied the implemented traffic generator to the performance evaluation of DiffServ networks and observed the effect of performance to the a value of the On/Off model, and performance of EF/BE class traffic by CBQ.

Purpose - This study investigates whether the effectiveness of self trait-advertisement versus communion-focused advertisement on product evaluations depends on a type of pride felt as ambient emotion. It also explores whether the mediating roles of cognitive and affective response to the effect of the advertisement type on product evaluation are moderated by types of pride such as hubristic pride or authentic pride. Research Design, Data, and Methodology - This research uses a restaurant service as the experimental object and employs a 2 (pride type: hubristic pride vs. authentic pride) × 2 (advertisement type: self trait-focused advertisement versus communion-focused advertisement) between-subjects design, with cognitive response and affective response as within-subject. Each experimental group consisted of 40 undergraduate students assigned to participate in the experiment. One questionnaire from the authentic pride and self-trait focused advertisement group and two questionnaires from the hubristic pride and communion-focused advertisement group were removed due to answer errors, resulting in a participant number of 157. The author conducts a 2 (pride type: hubristic pride vs. authentic pride) × 2 (advertisement type: self trait-focused advertisement versus communion-focused advertisement) ANOVA on advertised product evaluations, and to better understand the interaction effects, also conducts separate analysis of the hubristic and the authentic pride groups. Additionally, the study conducts mediated moderation analysis to check the mediation role difference of the cognitive response and the affective response to each advertisement on the interaction effects on product evaluations between the hubristic and the authentic pride groups. Results - The findings indicate that participants in the hubristic pride group more positively evaluate the product in self-trait focused advertisement, whereas participants in the authentic pride group more positively evaluate the product in communion-focused advertisements. In addition, the mediating role of cognitive response on the positive interaction effect of advertisement type and pride type on product evaluation is partially moderated by the pride type. However, the mediating role of affective response on the positive interaction effect of advertisement type and pride type on the product evaluation is not moderated by the pride type. Conclusions - The results of this study contribute to advertisement theory development by exploring interaction effects of ambient pride type and advertisement type on product evaluation, as well as to the theory of consumer behavior by exploring how pride type moderates the mediating roles of cognitive response on the positive interaction effect of advertisement type and pride type on product evaluation. From the perspective of the current research, advertisers should research what kinds of events consumers have experienced to increase the effectiveness of their advertisements, and use self-trait advertisements when consumers are grouped under ambient hubristic pride, and use communion-focused advertisements when consumers are grouped under ambient authentic pride. However, future research is necessary to discover the reasons why the mediating role of affective response to advertisements in the interaction effects of pride type and advertisement type on product evaluation is not moderated by pride type.

A current standard exist only on the surface tension in the current domestic wetting agent technology standards, so it is difficult to the performance evaluation of the wetting agent through the standard. So this study presents the optimized performance evaluation methods by scale model experimental equipment in order to present techniques for performance evaluation of wetting agents. The purpose of this study is to investigate validity of experimental results of the self-designed scale model experiment equipment by a comparative analysis of experimental results of the NFPA 18 experiment and the experiment using the self-designed scale model experiment equipment. As a result of a comparative analysis of experimental results of the NFPA 18 experiment that evaluate only the permeation performance on the contton and the experiment using the self-designed scale model experiment equipment that evaluate the permeation performance and fire extinguishing performance on wood flour, the discrimination of the permeation performance was confirmed in both the NFPA 18 experiment and the self-designed scale model experiment equipment. And a result of self-designed experiment equipment have clear discriminatory more than NFPA 18 by internal temperature measurement using the thermocouples.

Purpose: The purpose of this research was to evaluate the application of the Problem-Based Learning(PBL) in nursing with regard to the learning process and learning outcomes. Method: PBL modules were provided to the students so that they could identify the nursing problems related to nutrition, regulation, and elimination, and implement appropriate nursing interventions according to the problems. PBL was also used to develop ability to use self-evaluation for nursing intervention outcomes. The modules were developed by the authors for the course, Nursing 1(3 credits) at Y university, and used during one semester, March to June 2003. Evaluation of the learning process and learning outcomes was done by self-report questionnaires and a semi-structured self -report developed by the authors. Result: The PBL evaluation included role of the facilitators, group work process, and self-directed learning attitude. The students evaluated the facilitator's role positively in fostering positive interactions and cooperative study among students and stimulating students to apply various problem-solving strategies. Students evaluated their own group work performances as a good opportunity to improve their group work participation, contribution, cooperation, and leadership through the PBL session. Their responsibility for their own learning and develop self-directed learning attitudes to connect present learning to long-term goals. Conclusion: Critical thinking, problem solving skills, self-directed learning and group work accomplishments in undergraduate student nurses were fostered and improved through the PBL program.

Purpose: The purpose of this study was to examine the factors affecting body image among undergraduate students. Method: The research design for this study was a descriptive survey design using a convenience sampling. Data collection was done using self-report questionnaires with 319 undergraduate students located in 3 cities, Seoul, Gangneung and Seosan. Pearson correlation coefficients and hierarchical multiple regression with the SPSS Win 12.0 Program were used to analyze the data. Results: In the hierarchical multiple regression analysis, gender, height, weight and college major were controlled. Body surveillance and body shame significantly predicted 72.3% of appearance orientation. Sociocultural attitudes toward appearance and self-esteem significantly predicted 33.5% of appearance evaluation. Self-esteem and body surveillance significantly predicted 15.9% of health orientation. Self-esteem significantly predicted 23.3% of health evaluation. Conclusion: Findings from this study provide a comprehensive understanding of body image and related factors in undergraduate students in Korea. However, further study with a larger random sample and more a detailed research design is necessary.

The purpose of this study presents in Relations between cracks in self-leveling material and quality of floor groundwork surface are experimentally examined. As the first stage, the experiment to observe cracks in self-leveling material constructed on floor groundwork made from various kinds of concrete was carried. As a result, following basic findings were obtained. First, observation of cracks should be continued until an increase in width of cracks stop, without constructing any finishing material. Second, degree of cracks may be indicated quantitatively by the product of length and width. Finally, Cracks and separation is not be influenced by specimen size. Based on these findings, the method of predicting cracks by evaluating surface layer quality of floor groundwork will be established.

The intensity of industrial accidents has been increased while the number of industrial accidents has been decreased in theses days. It represents that we need safety guidelines based on personal attributes as well as physical attributes. This study tries to identify major causative factors for industrial accidents and to suggest an evaluation model based on personal attributes. Specifically, relationship between self-efficacy belief associated with industrial safety and other relative personal attributes has been analyzed. First, FGI(Focus Group Interview) was conducted to identify important personal attributes of industrial accidents. The questionnaire was prepared based on the results of FGI and was applied to identifying personal attributes. The relationship between personal attributes identified in this study and self-efficacy belief was assessed using fuzzy logic and fault tree analysis. The results of the assessment showed that self-efficacy belief was closely associated with industrial accidents. Specifically, workers with accident experience had higher level of self-efficacy beliefs than workers without accident experience.
