The purpose of this study was the development of the parenting stress scale, necessary to understand the details of the difficulties for a working mother having children from infant to preschooler. Relevant works were reviewed to collect 44 items for the questionnaire from the previous researchs, and additional 34 are combined as a set of measure items. The 78 items were analyzed for the fitness of structure based on the chi-square test and Cramer's V coefficients, and 35 were selected as a final set for the questionnaire. Further factor analysis on the 35 items showed that they could be selected 32 items of the 35 item scale and composed of 3 subscales; namely, the first factor(12 items) as‘typical stress due to the parenting’, the second(12 items) as‘pressures pertaining to the parental role and distress’, and the third(8 items) as’guilty to the parenting by others’. This final questionnaire composed of 32 items was also tested for the concurrent validity based on Pearson's correlation with Goldberg's General Health Questionnaire (GHQ), which is a well-known index to represent the socio-psychological stress. The correlation factor is .41(p<.001), which justifies the fitness of the newly designed questionnaire. To find the confidence level, the Cronbach α was evaluated, which results .88 for the overall questionnaire and ranges between .76 and .82 for each subcale. This parenting scale can be also utilized as a measure to exploit proper programs for the parent-child relations, parent education and rehabitilation of the family function.

The purpose of this study was to develope a questionaire measuring clothing behavior of elementary school children. At first, after pretest, the clothing behavior questionaire consisted of 70 items which were devidad. into 7 subscales i.e. Clothing interest. Clothing satisfaction. Clothing management, Clothing sex-role. Clothing comfort. Clothing conformity. and Clothing independence. Each item was rated on a 3-point scale. Samples were 447 boys and girls (4 th, 5 th, 6 th grade) of three elementary schools in Seoul. Korea. The data were analyzed by item analysis and factor analysis. Factor analysis was useful in attempting to establish contruct validity. Item validity was examined based on the correlation coefficients and item discriminating power through the chi-square. Reliability was examined based on the Cronbach's Alpha Reliability Coefficient and test-retest method. With this analysis the subscales were reconstructed to following 6 factors. Clothing conformity items were not clustered by the factor analysis. 52 items of 6 factors selected by the analysis. The factors characteristics were as follows: 1. Clothing interest (10 items) 2. Clothing satisfaction (11 items) 3. Clothing management (8 items) 4. Clothing sex-role (12 items) 5. Clothing comfort (6 items) 6. Clothing independence (5 items)

In the present study I developed the test for earth scientific creativity level and verified means to measure scientific creativity. I developed 22 test items and after being examined by science education specialist, 11 items were finally established, and these were applied to 104 middle students. Each answer paper was graded according to the standard answer that I developed and the results of analysis are as follows. First, to verify the validity of measuring means I figured out content validity. The content validity about test items and adequacy of evaluation goal was examined by 1 science education specialist and 3 middle school science teachers, 6 education graduate students. As a result of validity verification, the content validity was 82.7% and it showed that the test of earth scientific creativity was valid for evaluation goal and sub-factors of creativity. Second, to verify reliability of measuring means, I analyzed internal consistency of the test sheet of earth scientific creativity after finding correlation coefficient and Cronbach's $\alpha$. Cronbach's $\alpha$, the internal reliability coefficient, was 0.848. Therefore, it was verified that this test sheet of earth scientific creativity is reliable to measure the creativity of the middle school students. The correlation between sub-factors of creativity was statistically significant, and for the relation between the variables related to creativity, the originality was the most significant. This shows that in the procedure of scientific creativity and studying science, originality should be the most important factor.

Recently, many laundry home appliances have been released with Internet of Things (IoT) functions, but there are few quality evaluation tests for IoT functions. In particular, since IoT test items are not prepared for laundry home appliances applied with IoT functions, it is difficult to find the cause even if defects occur, and test institutions are limited in selecting test items related to IoT and conducting proper performance tests. In this paper, we design a test item framework that separates IoT test items into commonality and variability to identify product defects and causes for laundry home appliances with IoT features among products in the field of home appliances. Through the proposed research, manufacturers and test institutions can test the proper performance of laundry products with IoT functions, which can improve the completeness of the products and ensure reliability.

In accelerated life testing, a relationship is usually assumed between the stress and a parameter of the lifetime distribution. However, the true relationship is not usually known, and therefore, the experimenter may wish to provide protections against the likely departures from the assumed relationship. This paper considers an accelerated life test in which two stress levels are involved, and the lifetime of each test item at a stress level is assumed to have an independent, identical, exponential distribution. For the case where a first order relationship is assumed while the true one is quadratic, a procedure is developed for allocating test items to stress levels such that the bias and/or the variance of the estimated(log-transformed) mean lifetime at the use condition is minimized.
The purpose of this study was to promote the popularization of hospice services by providing the information about the influences of hospice training on participants. We compared differences of attitudes toward death between those of pre-training and post-training by use of questionnaire. This study involved 137 volunteers participating in the hospice training held by one hospice center located in K-city. The questionnaire was composed of 46 items, 21 items of general information and 25 items of information about attitudes toward death. We applied Park's translated version(1992), originally distributed by Thorson and Powell(1988), in the assessment of participants' changed attitudes toward death. Participants were asked to fill out the questionnaire before and after the hospice training. The data were analged by frequency. ANOVA t-test, paired t-test. The results were as follows, 1.Pre-training items holding a high rank were 'The subject about the future life after death is distressing'(F=5.20), 'No worry about any occurrences around the body after a funeral'(F=4.75), 'Having little interest in being laid in a coffin after death'(F=4.56); items holding a low rank were 'Having little interest in any occurrences around the body after death'(F=2.22), 'Willing to deal with the aftermath of the death in detail'(F=1.94), 'No fear to have an idea to be cancerous'(F=1.72). 2.Post-training items holding a high rank were 'No fear to be dead as a result of sufferings from long-lasting illness'(F=3.18), 'No fear to have an idea to be cancerous'(F=3.16)', Having little interest in the future life after death'(F=3.09); items holding a low rank were 'Unpleasant to be not able to move after death(F=1.74), 'Distressing not to know about the future life after death'(F=1.61), 'The subject about the future life after death is distressing'(F=1.60). 3.There were significant difference in participants' attitudes toward death. Compared with pretraining(F=3.97), more positive were developed in post training(F=2.30). The results of this study indicate that hospice training renders positive regards toward death to the participants. Therefore every human being, who is able to speculate about the meaning of death, has to be exposed to the hospice training. In conclusion, hospice training should be popularized in the near future.
This study identifies influential factors in regards to the purchase of celebrity fashion hot items and compares these factors in the age groups of teens and twenties. This study surveyed male and female consumers aged 10-20 years old for empirical analysis in July 2018. The study surveyed 322 consumers selected through online convenience sampling. Data were analyzed using SPSS for Windows 19.0, descriptive statistics, reliability analysis, ${\chi}^2$ analysis, regression analysis, ANOVA analysis, Duncan test, and t-test.

Background : Quality of professional nursing care is the most essential factor for survival and growth of nursing profession. Then, nursing professionals have responsibility for the evaluation of quality of professional nursing care. The purpose of this study was to develope an evaluation tool of nursing care for patients received gastrointestinal surgery with general anesthesia. This study was a primary work for the developement of a computer program for the evaluation of nursing care. Methods : This study was done through some consecutive steps. They were (1) Developement of items for the tool (2) Developement of an evaluation tool of nursing care quality for the G-I surgery patient (3) Test of reliability and validity of the tool. Two groups of experts and expert pannels who had much experience of the QA and the care of G-I surgery patients participated for developement of the items. 85 nursing records were used for the test of reliability and validity of the developed tool. The evaluation tools were developed with two types of scoring, norm-referenced tool and criterion-referenced tool. Results The system of items for tool was evaluation area evaluation item-indicator. There were 7evaluation areas which contained 32evaluation items which contained 7lindicators. Evaluation areas 1, 2, 3, 4 were for the evaluation of process and 5, 6, 7 were for the evaluation of outcome of nursing care for G-I surgery patient. For the test of interrator reliability, correlation coefficients of each scores of items and intragroup correlation coefficients were calculated. The average correlation coefficients between two rators were 0.65, 0.54 and the intragroup correlation coefficient were 0.99 and 1.00 by the types of scoring. The Cronbach alpha coefficients of the tools were 0.54 and 0.46 by the types of scoring. The average content validity index of the items was 0.95 from 4 pairs of experts. Because there were significant differences between some scores of quality of nursing care of 3 general hospitals regardless of the types of scoring, the tools could be thought to have some construct validity. And also, there were significant correlations between some scores of quality of nursing care and admission days and admission days after surgery regardless of the types of scoring, the tools could be thought to have predictive validity. Conclusion In this study, the evaluation tool of nursing care was developed for the very specified group of patient, G-I surgery patient. And the items were developed and tested by the experts of nursing practice. Because of these reasons, it was supposed that the tool could be used effectively in nursing pratice. And the procedures for the development and the test of the evaluation tool of nursing care in this study were supposed to be used for the developement of other tools.
