  • Purpose: This study was done to develop a pregnancy nutrition knowledge scale and to examine the relationships between pregnancy nutrition knowledge and eating habits in pregnant women. Methods: With convenient sampling, 189 pregnant women who used community health centers for their ante-natal care were recruited. Data were collected using a self administered questionnaire including items on pregnancy nutrition knowledge (18 items) developed by researcher and items on eating habits (14 items). Cronbach's alpha and exploratory factor analysis were examined to test reliability and construct validity of the scale. Pearson's correlation coefficients were used to identify the relationship between pregnancy nutrition knowledge and eating habits. Results: Cronbach's alpha of 18 items was .80. In factor analysis using principal components, 6 factors explained 65% of the total variance. The level of pregnancy nutrition knowledge was not sufficient but correlations between pregnancy nutrition knowledge and some of eating habits were significant. Specifically, pregnancy nutrition knowledge was positively correlated with good eating habits and negatively with bad eating habits. Conclusion: The pregnancy nutrition knowledge scale developed in this study is acceptable for nutrition education led by nurses. Pregnancy nutrition knowledge and eating habits are considered as major variables for ante-natal nutrition education. In future studies, explorations are needed on dietary intake and physiological indices in pregnant women, comparison of women at risk with those not at risk, and development of nutritional education programs for pregnant women.

  • The study attempted to explore the dimensionality of mother's psychological well-being. The major purpose of the study was aimed at establishing the construct validity regarding the instrument of assessing mother's psychological well-being. Instrument for assessing psychological well-being was developed with 9 variables(sense of control, sense of achievement, sense of confidence, sense of acceptance, sense of intimacy, sense of assistance, sense of immersion, sense of hope, and sense of satisfacion) in 3 dimensions(sense of competency, sense of relation, and sense of improvement) with 4 rating scales of 102 items. After the scale development, the estimates of reliability for the 9-variable scales were Cronbach's ${\alpha}=.71{\sim}.90.$ The correlation between the two scales, Psychological Well-Being Index(Franklin, 1996) and Psychological Well-Being(Ryff & Keyes, 1995) was .21~25. The subjects were divided two groups by the score of the Mother's sense of Psychological Well-Being. And the group has hiher score in Mother's sense of Psychological Well-Being showed the higer score of Perceptions of Parental Role Responsibilities Scale(t=3.24, p=.002).

  • A slightly modified version of the Quality-of-Life after Myocardial Infarction (QLMI) questionnaire developed by Oldridge and colleagues was applied in a self-administered mode to patients with suspected acute myocardial infarction (AMI) in a randomized controlled trial of secondary prevention. Acceptability of the questionnaire was good, with 93% of responders answering all items. Factor analysis suggested three quality-of-life (QL) dimensions which we called 'emotional', 'physical' and 'social'. These differed somewhat from the dimensions proposed by Oldtidge and colleagues. However, a sensitivity analysis showed relative invariance of results to weighting schemes. Scores on our three dimensions were responsive to differences between the treatment groups, and demonstrated construct validity based on associations between the measured QL and variables expected to affect QL. We conclude that the QLMI questionnaire has good potential as an instrument for assessing QL in post-AMI patients and that it can be successfully self-administered.

  • Objectives: This study was to develop a reliable and valid instrument measuring the reproductive health promoting behavior of undergraduates. Methods: The initial questionnaires were made of 106 items from four domains through literature review. All questionnaire items were revised by an expert group and a pilot test. Data were collected using the revised initial questionnaire of men's 58 items and female's 64 items from 634 male and 685 female undergraduate students. The collected questionnaires were analyzed by factor analysis using varimax rotation to evaluate the construct validity. Results: According to the gender, two measurement were invented and analysed separately. Four common factors consisting of 'safe sex', 'sexual responsibility', 'genital health management' and 'STD prevention' were discovered in both groups. The 'genital hygiene' factor was added as a female factor. Male students' scale was made up 4 factors 16 items and female students' scale was made up 5 factors 18 items. Cronbach's alpha for male scale was estimated to be .892 and female scale to be .882. Conclusions: This scale will make it possible to measure the level of reproductive health among Korean university students. This scale may be useful for developing effective methods of education as well as policy programs for improving the reproductive health of Korean university students.

  • The purpose of this study was to investigate beginning elementary teachers' beliefs about the nature of science. Defining teachers' beliefs as a broad construct, we tried to examine the teachers' understandings about the nature of science. The methodology of this study was a qualitative approach through semi-structured interviews. In an urban area of Korea, five beginning elementary teachers were chosen. The cross-case and grounded theory study design were adopted for the data analysis. The results of data analysis were checked by teachers for internal validity. This study identified the teachers' beliefs about the nature of science suggested by many researchers. The results of this study showed that: 1) beginning elementary teachers did not well understand and were unfamiliar with the meanings of various terms about the nature of science; 2) their beliefs abut the nature of science were broad and various; 3) they understood some parts of the nature of science; 4) there were differences within their understandings about subconcepts of the nature of science.

  • All human spatial behavior and psychological stress are affected by the 'Privacy'of each space. This Paper deals with the theoretical review of 'privacy'concept and establishment of 'Privacy Model' that can be a useful design tool. 'Privacy Index(Pl)' model of 10 point scale, which is based on 'Hierarchic system of Privacy' in urban spaces by Chermeyeff and Alexander(1963), was established as a hypothetical model in this study. And'Activity Suitability', based on each hierarchy of primacy level, was investigated at each site to construct the validity of 'Privacy Model'. Total 67 sites were investigated by on.-site questionnaire in 3 types of outdoor spaces, (Park), (Campus), and (Garden) respectively. The major results are as follows; 1. The P7rivacy level of earth spaces, distributed from to in and . and (Groun Private> spaces are dominant In , spaces are dondnant 2, Privacy level, based on , showed higher privacy level than that of . This means the criteria of each privacy level should be modified for more specific space. The . could be derived from the (Activity Suitability) of each space. 3.The cognition of privacy level. by user group, showed no significant difference in dach group by sex, age, education, and job, respectively.

  • With the development of the American Customer satisfaction index (ACSI), research on customer satisfaction measurement or evaluation methods have become significant in the last decade. Most of international customer satisfaction barometers or indices are evolved based on the cause and effect relationship model of ACSI. Of critical importance to validity of customer satisfaction indices is how to construct a measurement attribute or indicator model and provide an effective implementation method effectively. Quality Function Deployment (QFD) is a very useful tool for translating the customer voice into product design through quality engineering. In fact, this is a methodology for measuring and analyzing evaluation indicators by their relationship matrix. In this paper, we will make an effort to integrate the framework of QFD into the measurement problem of customer satisfaction, and also develop a new multi-phase QFD model for evaluation of Customer Satisfaction Index (CSI). From the houses of quality in this model, the evaluation indicators impacting on customer's global satisfaction are identified by means of their relationship matrix. Then the evaluation indicator hierarchy and its measurement method for the customer satisfaction index are presented graphically. Furthermore, survey data from the Chinese automobile maintenance sector and a relevant case study are utilized to show the implementation method of the QFD model used to measure and analyze of customer satisfaction.

  • Compared with the research on consumer engagement in brand community, the research on consumer engagement in brand public has been relatively less. This research aimed at exploring how brand public characteristics such as information variety, various communications and no limitation in expressing self affect the brand public engagement. 274 questionnaires answered by Chinese consumers are used to conduct analysis. Principal component analysis is used to test the reliability and validity of each construct, and structural equation model is used to test hypotheses. The study finds the positive effects of information variety on information benefits, those of various communications on social benefits, and also positive roles of no limitation in expressing self to brand-related self-expression motivation. And each of the information benefits, social benefits and brand-related self-expression motivation is proved to positively affect brand public engagement. The study implies that marketers should give attention to characteristics of brand public, and provide the ways by which members of brand public engage the brand. Additionally, marketers should pay more attention to both direct and indirect engagement activities of consumers toward brand public in social media to better understand their target consumers.

  • A fluid-structure-isolator interaction program was developed in this study. The behavior of liquid regions are simulated by the boundary element method, and then the technique of analyzing the free surface motion in time domain is developed by using the nonlinear free surface boundary condition(NFBC) and the condition of interface between the structure and the fluid. Structure regions are modeled by the finite element method. In order to construct the governing equation of the fluid structure interaction(FSI)problem in time domain, the finite elements for a structure and boundary elements for liquid are coupled using the equilibrium condition, the compatibility condition and NFBC. The isolator is simulated by equation proposedin 3D Basis Me. In order to verify the validity and the applicability of the developed fluid- structure -Isolator interaction program, The horizontal forced vibration analysis was performed. The applicability of the developed method is verified through the artificial seismic analysis of real size liquid storage tank.
