Purpose: This study's purpose is to classify and analyze caregivers' recognition of the elderly suicidal intents. Methods: This study uses applied Q-methodology to measure human subjectivity in depth. Concretely, 35 statements are composed in depth interviews and literature investigation. Then, Q-cards and distributive chart of Q-sampling were given to 25 caregivers randomly-selected, who were asked to arrange them on a 7-score based. After coding Q-factor analysis is carried out with the PC-QUANL program. Results: Four types of indicators of the elderly suicidal intents were identified by the caregivers. These are Knowledge-based recognition, Behavioral measure based recognition, Negative comprehension and Sympathy. Conclusion: In this study, four types of recognition were yielded among the caregivers and the characteristics of each type were analyzed. These findings may be useful in assessing suicidal potential and nursing interventions.

The value of housewife occupation is likely to be underestimated because of its invisibility and myth. This study was performed to investigate social meaning of housewife occupation in the modern society using concept of psychological benefit and cost of full-time housewife.

The data were analyzed by the statical methods such as frequency, mean, percentile, Factor Analysis, t-test, ANOVA, Duncan’s multiple range test, Person’s Correlation, and Multiple Regression Analysis through the SAS program package. The major findings of this study are as followers : First, housewives’ usage and management behavior of credit cards was a positive relationship between home management behavior pattern. Second, housewives’ cognition of credit cards showed a significant positive relationship with usage and management behavior of credit card. Third, the most influencial variables on housewives’usage and management behavior of credit cards were their value and home management behavior pattern.

This work was conducted to observe the housewives´ recognition about GMO products and their opinions about the development and production of GMO. Seventy eight percent of the subjects in this study were aware of GMO and GMO product which is best known to them was bean. Only 6.2% of the subjects considered GMO as safe and 42.1% did not know whether it is safe or not. Most of the subjects were unlikely to choose to purchase the GMO because of unproved safety, but many subjects were willing to purchase if the safety was informed with high reliability, even though 25.9% of the subjects were still negative. But when GMO product is offered with low price compared with ordinary products, only 24.6% were willing to purchase, showing that the safety was considered more important than the low price.

This paper proposes the way of improving learning speed in Levenberg-Marquardt algorithm using the principal submatrix of Jacobian matrix. The Levenberg-Marquardt learning uses Jacobian matrix for Hessian matrix to get the second derivative of an error function. To make the Jacobian matrix an invertible matrix. the Levenberg-Marquardt learning must increase or decrease ${\mu}$ and recalculate the inverse matrix of the Jacobian matrix due to these changes of ${\mu}$. Therefore, to have the proper ${\mu}$, we create the principal submatrix of Jacobian matrix and set the ${\mu}$ as the eigenvalues sum of the principal submatrix. which can make learning speed improve without calculating an additional inverse matrix. We also showed that our method was able to improve learning speed in both a generalized XOR problem and a handwritten digit recognition problem.

A food safety survey was conducted to assess the housewives' handling practices and consumption of potentially risky foods in family home. More than $40\%$ of the respondents wash their hands without soap or use their wash towels after contact with potentially risky foods such as meat, poultry, fish, shellfish, raw eggs, meat processed foods, raw fruits and vegetables. Over half of the respondents have consumed undercooked eggs without recognizing the potential health risk of consumption of raw eggs. $34\%$ of the respondents do not wash their hands after breaking raw eggs, indicating high risk of cross contamination while handling raw eggs. More than $60\%$ of the respondents just use running water to wash fresh fruits and vegetables. $78.9\%\;and\;45.2\%$ of the respondents have consumed sushi/sashimi or raw oysters, respectively in the past 12 months. The results of this study indicate the substantial risks of unsafe food-handling practice at the points of cross-contamination, cooling practices, storage time, and consumption of potentially risky foods at home. Considering the housewives' participation in school food service, development of food safety education program for the housewives is needed to promote safe handling practices of potentially risky foods.
