  • The purpose of this study is to investigate some Influencing factors related to the wealth perception and property increase of 519 women in Seoul. The research was conducted from the end of February 15 to the beginning of January 20, 2009. The figures obtained were analyzed by frequency, percentage, mean, x-test, t-test, F-test, chi-square, and Duncan's F-test with SPSS pc+ The major findings of who study are summarized as follows: l.There were significant differences between the wealth recognition (economic plan affirmative and negative perception of wealth) for women according to social and psychological variables; economic plans have a higher value for married women, older women, those who have followed a postgraduate university course, those with higher income and expenditure, higher life satisfaction, and high and middle satisfaction with their economic life. In particular, economic plans varied significantly according to expectation of wealth in old age, and future economic prospects in the middle group. 2. Increased wealth and economic according to social and psychological variables (marital status, age, education, income, expenditure, life satisfaction, satisfaction with economic life, expectation of wealth in old age, future economic prospects) were shown to be associated with the following methods of increasing property: use of savings banks (p<.001) showed a rate of deposit of 20%-40% (p<.001) saving and thrift was a practice (p<001) that was related to the cost of living; and education expenditure (p<.001) as a property preparation period was exhibited in women aged 25-30 (p<.001). 3. There were significant differences in the recognition of wealth according to strategies for increasing wealth. There were no significant differences between mean of property acquisition and point of expenditure or the property preparation period in the perception of wealth. The related variables in rate of deposits were under 20% according to economic plan and negative wealth perception. In contrast, in the middle and high group, the economic plan and negative wealth perception were 20%-40% in relation to the rate of deposits. Variables related to the action of saving and thrift and property acquisition were practiced in the low and middle group of affirmative wealth recognition and the high group of negative wealth perception. The high group for wealthrecognition and the low group for wealthnegation exhibited little savings, thrift, and property accumulation. Those variables which point an expenditure the cost of living were education expenditure in all groups of negative wealth perception. The women in the study practiced more soundness economic planning according to their increased wealth and economic strategy. This study suggests that women should have positive wealth perception in their lives.

  • This study comprehensively analyzed domestic and foreign literature related to the value and impact of libraries on education, social behavior and economic conditions, developed a survey to investigate the librarians' perception of the libraries' value and impact, and accordingly investigated the perception of librarians according to the types of libraries in which they worked, public versus university. The results showed that the impact is greatest on education and literacy with a mean score of 3.98, followed by their social impact with 3.67 and their economic impact with 3.46. When subordinate items were analyzed it was found that the librarians perceived that the role that libraries are playing in the education area is expanding and their impact on reading and literacy is becoming greater and greater. Libraries were viewed as essential elements for education and the education system. When the difference in perception related to the impact of libraries was compared by types of libraries, the librarians in public libraries tended to rate their facilities higher than the librarians working in universities on most of the items.

  • This study examined the impact of sonority profiles, positional differences and L2 proficiency on Korean EFL learners' perception of English biconsonantal clusters, using nonce words. The overall results showed that major predictions of the sonority-based typological markedness on consonant clusters were supported, as obstruent plus sonorant and sonorant plus obstruent sequences were better perceived than obstruent only or sonorant only sequences. Yet, some consonant clusters did not show a preference for sonority profiles. Positional effects were also confirmed, as word-initial biconsonantal clusters were better perceived than wordfinal ones across all the participant groups. Participants' English proficiency turned out to be also important in the perception of consonant clusters, since university students' mean rate of accuracy was highest, followed by that of high school students, which in turn followed by that of middle school students. Further, the effects of other factors like frequency and stimuli on speech perception were also addressed, along with some implications for future research.

  • Objectives: To assess the nurses' hand hygiene (HH) knowledge, perception, attitude, and self-reported performance in small- and medium-sized hospitals after Middle East Respiratory Syndrome outbreak. Methods: The structured questionnaire was adapted from the World Health Organization's survey. Data were collected between June 26 and July 14, 2017. Results: Nurses showed scores on knowledge ($17.6{\pm}2.5$), perception ($69.3{\pm}0.8$), self-reported HH performance of non-self ($86.0{\pm}11.0$), self-reported performance of self ($88.2{\pm}11.0$), and attitude ($50.5{\pm}5.5$). HH performance rate of non-self was $Y_1=36.678+0.555X_1$ (HH performance rate of self) (adjusted $R^2=0.280$, p<0.001). The regression model for performance was $Y_4=18.302+0.247X_{41}(peception)+0.232X_{42}(attitude)+0.875X_{42}(role model)$; coefficients were significant statistically except attitude, and this model significant statistically (adjusted $R^2=0.191$, p<0.001). Conclusions: Advanced HH education program would be developed and operated continuously. Perception, attitude, role model was found to be a significant predictors of HH performance of self. So these findings could be used in future HH promotion strategies for nurses.

  • For the user-centered interior space design, a designer needs to carefully focus on the details from which the user must keenly observe or concentrate on the space and how to deliberately check the image of the space. Following this view, for the user-centered interior space design this study analyzes the way which the space is represented from the perspective of the image assessment. The results obtained from this study are summarized as follows: First, this study analyzed the characteristic of space image change in the form of cross-comparison between one space and a rotated space. With analyzing of an eye fixation by showing the space, the space images of "concentration-dispersion" and "strengthening-weaken "have an important role in the analysis of the perception of space. it confirmed that the method of space perception was changed by rotated the space. Second, With changing quantities of image and extraction of deviation from adjective in survey, it quantitatively graps that respondents of feel in space perception by changing the space and "concentration" and 'dispersion" for process of space choice. The results of the research can provide important basis to judge the changing of space perception by visual perception. Third, through the analysis of image change rate and deviation rate, the characteristics of image change with space change can be analyzed. The results derived from the study provide the evidence to support the image change by space rotating.

  • Objectives : The purpose of this study is to compare the ability of facial affect perception among schizophrenia patients, their first degree relatives, and normal control subjects. Methods : Thirty five patients with schizophrenia, 22 first degree relatives, and 34 normal control subjects were recruited in this study. All three groups were matched for age and education levels. The facial affect identification test(FAIT), and neurocognitive test were applied. In the FAIT, the correct response rate, perceived intensity, and sensitivity for 6 kinds of affects were compared among three groups. Results : We found that correct response rate of sadness and anger were decreased in the schizophrenia patients compared with the normal control group. Also the schizophrenia patients showed reduced sensitivity for all six affects compared with the normal control group. The ability of facial affect perception in first degree relatives of schizophrenia patients was decreased but there were not any significant differences compared with normal control group. Conclusion : This study confirmed significantly reduced ability of facial affect perception in schizophrenia patients compared with normal control. Decreased ability of facial affect perception in first degree relatives suggests that affective sensitivity can be influenced by genetic predisposition.

  • The purpose of the study was to evaluate the perception of importance about prerequisite program(PRP) of dietitians. A questionnaire was developed to achieve research objectives and sent to random samples of 450 dietitians by a mail from July to August in 2000 ; 242(54%) responses were analyzed. The respondents used three-point-scale to rate their perception of importance about PRP from 1-"will be necessary" to 3-"very important". All statistical analyses were conducted using SAS package(version 8.12) in order to have means, standard deviations, One-way analysis of variance, Duncan’s multiple range test and t-test. The study results were summarized as follows. The rates of perception of importance about PRP were significantly different from 21 of the 37 contents among business and industry, health care and school foodservice and were significantly different from 16 of the 37 contents among direct and contract management(p<.05 or p<.01 or p<.001). Dietitians in business and industry had lowest perception of importance about PRP of other respondents. Generally, the item related to ‘‘employee hygiene practice’ had the highest perception level score among PRP in foodservice facilities. Results indicate that there is a need for increased education of dietitians about PRP and appropriate practices.

  • The purpose of this study was to investigate elementary school students' perception of food waste as well as to identify factors affecting the plate waste rate of school foodservice in the Gyeongnam area. Questionnaires were distributed to 280 students from June 20 to July 5, 2011 and a total of 279 were analyzed. The results of this study were as follows. First, the main reason of plate waste was 'big portion size', which suggests that portion size should be adjusted. Second, the attitude for food waste reduction was 3.67 based on a 5-point Likert scale (1: strongly disagree, 5: strongly agree). Third, the average plate waste rate of school foodservice was 18.65%. Fourth, there were four factors affecting plate waste rate; balanced/unbalanced diet, satisfaction of school foodservice, need for nutrition education related to food waste, and attitude towards food waste reduction. The plate waste rates of the students who ate a balanced diet were significantly lower than those of the students who ate an unbalanced diet (P<0.001). The plate waste rates of the students who were satisfied with school foodservice were significantly lower than those of the students who were unsatisfied (P<0.001). The plate waste rates of the students who recognized the need for nutrition education were significantly lower that those of the students who did not recognize this (P<0.01). Finally, the students' attitudes towards food waste reduction were significantly negatively correlated with plate waste rate (P<0.01). In conclusion, in order to successfully reduce plate waste in school foodservice, nutrition education should be provided on proper portion size, balanced diet, and food waste. Further, introduction of partial self-service by school foodservice should be reviewed, and strategies for the improvement of school foodservice satisfaction should be applied.

  • This study investigates the facility use status of smart farming farmers to improve facility use rate of farmers. To this end, a survey was conducted on smart farming farmers in Jeonnam province, and the main survey contents are as follows: facility use rate, the reasons for low facility use, the perception of the introduction and use of smart farming etc. As a result of the survey, many farmers have introduced smart farming facilities even though they do not have enough use capacity. Thus it is necessary to improve the use capacity of farmers. Second, the average facility use rate of farmers was 65.1%, and 37.5% of respondents did not use even 50% of smart farming facilities. To improve the use rate, education on how to use facilities and continuous consulting support for farmers are needed. And the largest number of farmers perceived the risk like crop damage or facility failure due to poor use of facilities. This means that risk management due to the smart farming facilities is important. Third, farmers answered that rapid and continuous repair service were the most important when using facilities. Thus it is important to foster rear industries such as maintenance companies to stably operate smart farming facilities.
