This study analyzed some of the discrepancies in quantitative and qualitative data focusing on cognitive and affective achievement in science education. Academic and affective achievement score of 308 high school students were collected as quantitative data, and 33 students were interviewed for qualitative data. We examined the causes and types of discrepancies in terms of testing tools. As a result from quantitative data, there were a large number of students with a big difference between subjects in cognitive achievement, and constructs in affective achievement. More than 20% of the students did not match tendency between achievements in two areas. Through interviews, some examples such as intentional control of science learning for future study and careers, different responses by differences in perception between school science and science, appeared. A comparison of quantitative data by testing tool between qualitative ones and interviews showed conflicting result, where most students evaluated themselves differently from their own quantitative data. That is due to the students' interaction with the testing tools. Two types of discrepancy related to testing tool are found. One is 'the concept difference between the item developer and students,' the other is 'the difference between students' exposed response and their real mindset.' These are related to the ambiguity of the terms used in the tool and response bias due to various causes. Based on this study, an effort is required to elaborate the testing item that matches students' actual perception and to apply students' science learning experience to testing items.

This article is concerned with the values of the BICOF in terms of the urban revitalization. The values of the BICOF cover the economic value, social value, cultural value and city image value. The 13 indicators for measuring the values of the BICOF are developed. The article examined how the related stakeholders identified the BICOF's values on the Bucheon City by using AHP method. In addition, the objectives and programmes of the BICOF are analyzed in the perspective of the urban revitalization. As a result, the recognition of the BICOF's values varied according to the stakeholders. In addition, the result of AHP analysis indicates that the cultural values and image values should have priorities in comparison with the social values and economic values. This recognitions is different from the recent formal statements that BICOF's economic values should be emphasized as a priority. The article concludes that the identity of the BICOF should be established in the base of building the value consensus among the related stakeholders.

The purpose of this study was to extract the evaluation factors and assess the relative importance between the factors. For this purpose, the evaluation factors were extracted through literature review and the process of brainstorming with experts, who are related to port security. The evaluation factors were then classified into four higher factors and twelve sub- factors through the use of the AHP method. A survey on the classified factors was conducted by experts composed of public officials, port authority employees and education institutions officials. We also carried out statistical tests to determine the perception gap of weights between the groups. As a result of a relative importance analysis of strength, the security operating system factor was highest, followed by improvement of hardware facilities and increase of security personnel. There was a difference in perception among the groups in policy support, facility support and personnel resources budget support. The results of the analysis show that the strength operating system through the establishment of an integrated monitoring system is a priority. It is necessary to understand the difference of perception between groups and build a systematic cooperation system. The evaluation factors extracted from this study can be used for the measurement of port security efficiency in further work.

Purpose: This study was conducted to identify factors affecting nurses' organizational commitment of the JCI. Methods: This cross-sectional study was performed using questionnaire. Data were collected from 198 nurses who worked at one hospital from 5 to 14 May 2013. Tools were used general characteristics, perception(Yang & Choi, 2014), job stress(Park, 2005), organizational commitment(Mowday, Porter, & Steers, 1979). Results: The scores of perception, job stress, and organizational commitment of the JCI were 3.21/5, 4.08/5, and 2.65/5 respectively. Organizational commitment was significantly different according to degree. A positive correlation was observed between perception and organizational commitment. Organizational commitment was negatively correlated with job stress. The explained variances for organizational commitment was 26.3% and factors affecting nurses' organizational commitment were degree, perception, and job stress. Conclusion: These results showed the significant factors for nurses' organizational commitment of JCI. These findings can be utilized to development of strategies for reducing job stress, and enhancing perception of JCI.

National Health Insurance Corporation initiated Home and Community Long-term care Agency Quality Assessment(HCLA-QA) program in 2010. This study aims to explore long-term care agencies' perceptions and attitudes toward HCLA-QA program, focused on the home-visit care agencies. Total 473 agencies completed the questionnaires(response rate 13.6%), using the e-mail and fax survey methods with high-capacity web-fax server of NHIC. On the results of this study, we found the agencies' different perceptions and attitudes on HCLA-QA program according to their quality ratings as QA results. Compared to the agencies with low quality ratings, the agencies with high quality ratings tend to have more time for preparation, better understandings about HCLA-QA program, more positive perceptions that quality indicators generally are valid, and more affirmative attitudes that the notifications of QA results are helpful for agencies. Our findings can be very useful for establishing strategies for improving the HCLA-QA program. The policy makers, the insurer, and the agencies need to consider the opinions of the agencies with high quality ratings as well as the ones with low quality ratings.

In this study, we investigate the usefulness of the measures of the 2008 Korean Public Library Operation Assessment as perceived by librarians in practice using a survey. The survey was answered by librarians in large, medium, and small-sized libraries managed by local autonomous bodies and in large-sized libraries that belong to local education authorities. The survey results show that whereas the usefulness of items was higher in planning area and those items that can be easily counted, and usefulness of items in human resources and facilities was lower. There are no significant results in differences by library size and by the characteristics of librarians. Based on the results, we suggest a direction for the improvement of the Korean Public Library Operation Assessment.

This study examined the difference between parents' and teachers' recognition about problem behaviors of children. The findings showed that there was a distinct difference between parents' and teachers' recognition about all problem behaviors of children. Especially, teachers had more recognition about problem behaviors of children than parents. And the reactive interaction and the actual prevention in educational institutions were preferred in the difference between parents' and teachers' recognition about a teaching strategy for children, such that teachers had significantly higher recognition about a teaching strategy for children than parents did, while there was no significant difference in the strategy for social emotion. This means that teachers should originally control and manage various problem behaviors based on the common teaching strategy, which is socio-emotionally recognized, rather than the biased teaching strategy. But the teaching strategy of reactive interaction is preferred in accordance with the type of problem behaviors between teachers and children and the children who show problem behaviors. Especially, teaching strategies of reactive interaction and actual prevention focused on the inhibition and prevention of children's problem behaviors are preferred in light of children's characteristics of many unexpected problem behaviors.

This study examines the perception and trust of Korean society and people among students and adults using the indigenous psychological analysis. A matched sample of 1,107 participants, consisting of 369 students, their mothers and their fathers completed a questionnaire developed by the present researchers. The results indicate that parents more likely than adolescents to hold negative views of Korean society. Adults are more likely than adolescents to view Korean society as showing high ingroup favoritism, to be insecure, to be conservative, to be corrupt, and to have social inequities. Both groups agree that Korean society is not rational nor democratic, but believe that it has the potential for progress. Second, parents are more likely to hold negative views about Korean people. Adults are more likely than adolescents of viewing Korean people as overly conscious about social face, emotional, selfish, exclusionary, and conceited. Both adolescents and their parents agree that Koreans are cooperative, full of jung (deep affection and attachment), and sincere. Third, adults are less likely to trust Korean institutions than adolescents. Adults are less likely than adolescents to trust National Assembly, political parties, and unions. Adolescents are more likely than their parents to trust family members, school friends, teachers, and government employees. These results indicate that adolescents have higher trust of Korean society and people than their parents. Fifth, the overall results indicate that both group perceive Korean society as showing high ingroup favoritism and corruption. In terms of Korean people, respondents had a more balanced view of perceiving them as highly sensitive to social face and being emotional, while also perceiving them as cooperative and full of jung. The trust of Korean institutions were generally low, especially the National Assembly and political parties. However, the trust of family was very high, followed by trust of school friends and teachers. The trust of government employees was low and this was especially the case for politicians.
