  • The purpose of this study was to verify the construct validity of self-evaluated writing scale for students with disabilities who had difficulties in writing. After interpreting the Here's How I Write scale developed by Goldstand et al. (2013), we administered Delphi survey to 40 special education professionals, calculated the content validity ratio and decided the final scale of 21 questions applicable to Korea. Additionally, we carried out the scale to 350 disabled and normal students for testing construct validity. The main results are as follows: For both students with disabilities and without disabilities, the overall internal consistency of scale are higher than .89 and the internal consistency of factors of scale are higher than .66. The confirmative factor analysis using AMOS 21.0 and SPSS 21.0 to verify construct validity showed fit index at relatively satisfactory level for students with disabilities and without disabilities. Furthermore, while there were relatively strong convergent validity and discriminant validity in the sub-factors of scale for students without disabilities, the level of convergent validity and discriminant validity were relatively lower for students with disabilities.

  • Due to recent demographic changes, employees from diverse generations now work together in organizations. Thus, there is a need for research on intergenerational cooperation. However, the lack of valid and reliable measures to capture intergenerational climate in the workplace is an obstacle to research. Therefore, we translated the Workplace Intergenerational Climate Scale(WICS) into Korean and validated it with a sample of 1,052 Korean full-time employees. Firstly, we conducted an exploratory factor analysis by using sample 1(N = 460) and revealed a five-factor solution. Secondly, the confirmatory factor analysis(sample 2; N = 592) showed a good model fit of the correlated five-factor model. Thirdly, the scale's discriminant and convergent validity was supported by negative correlations with four types of existing ageism scales and by positive correlations with trust, organizational commitment, work engagement, psychological safety, intention to remain, job satisfaction, and communication satisfaction. Moreover, it further demonstrated significant incremental validity in predicting positive outcome variables even when controlling for pre-existing agism scales. Lastly, we confirmed strict measurement invariance of the scale between the age groups(below 40 versus above 40). The findings support the reliability and validity of the Korean version of WICS among Korean employees. The scale will be broadly applied to measure intergenerational climate of organizations and provide practical implications for HR management.

  • Purpose Online Peer-to-peer lending (hereafter P2P lending), is a new method of lending money to unrelated individuals through an online financial intermediary. Usually in the online P2P transaction, individuals who would like to borrow money (hereafter borrowers) and those who would like to lend money (hereafter lenders) have no previous relationship. Based on enormous previous studies, this study develops an integrated model, particularly for the online P2P lending environment in China, to better understand the critical factors that influence lenders' intention to lend money through the online P2P lending platform. Design/methodology/approach In order to verify the hypotheses, we develop a questionnaire with 42 survey items. We measured all the items on a five-point Likert-type scale. We use Sojump.com to collect questionnaire and gather 246 valid responses from registered members of Renrendai.com. We analyzed the main survey data by using SPSS 18.0 and AMOS 20.0. We first estimated the reliability, validity, composite reliability and AVE and then conduct common method bias test. The mediating role of trust in platform and in borrower has been tested. Last we tested the hypotheses through the structural model. Findings The results reveal that service quality, information quality, structural assurance, awareness and reputation significantly impact lenders' trust in the online P2P lending platform. Second, awareness, reputation and perceived risk significantly impact lenders' trust in borrower and lending intention. Third, trust propensity has a positive effect on lenders' trust on borrower. Last, awareness, reputation, perceived risk, platform trust and borrower trust can directly impact lenders' lending intention.

  • A trustworthy counseling relationship is an important variable for an effective counseling progression and counseling goal achieving. This study was designed to examine effects of ambivalence over emotional expressiveness and counselor perception on working alliance. Objects of this study were clients in university counseling centers, counseling centers for adolescents and private counseling institutes. Clients were asked to answer an ambivalence over emotional expressiveness questionnaire, a counselor perception questionnaire and a working alliance questionnaire. Total 97 cases were collected and the data was analysed by multiple regression method. The results were as followed; ambivalence over emotional expressiveness was not significantly related to working alliance. However, counselor perception was significantly related to working alliance. That is, the more positively counselors were perceived, the better working alliance was. Effects of counselor perception's sub-factors on working alliance were also found; attractiveness was significantly related to working alliance but trustworthiness and expertness were not. An interaction of ambivalence over emotional expressiveness and counselor perception on working alliance was also significant. As for those clients who were high at the ambivalence over emotional expressiveness, working alliance was increased in case they had positive counselor perception. In conclusion, it is not personality factors but that counselor perception that makes the difference in working alliance

  • Many adult diseases(cerebral apoplexy, athymiait, etc.) result from hypertension, blood circulation disturbance and increment of HBP. In early diagnosis of these diseases, MRI, X-ray and PET have been used rather aim for treatment than prevention of a disease. Since, cerebral apoplexy and athymiait have been caused to the regular/irregular persons, it is very important to measure HBP which has connection with cerebral blood low state. HBP has more diagnosis elements than that of BP. So, we can diagnose accurate hypertension by measuring of HBP. But, existing sphygmomanometers and automatic BP monitors can not measure HBF, and can not execute complex function(measuring of BP/HBP, blood flow improvement). The purpose of this paper is to develop the system and algorithm which can measure BP/HBP for accurate diagnosis. Also, we extracted diagnosis factors by the correlativity analysis of BP/HBP. The maximum pressure of HBP corresponds to 62% that of BP, the minimum pressure of HBP corresponds to 46% that of BP. Therefore, we developed the multi function automatic blood pressure monitor which can measure BP/HBP and improve cerebral blood flow state.

  • The purpose of this study was to develop the empowerment scale instrument and to investigate the perception and needs regarding to the empowerment as home economics(HE) teacher. Respondents in this study were 234 HE teachers. questionnaires were collected by e-mail in the integrating online computer system. SPSS(Statistical Package for the Social Science) 10.0 package and AMOS 6.0 were used to analyze the data. Factor analysis and reliability analysis were used to develop the empowerment scale instrument. Means and Borich requirement analysis were used to describe the perception and needs regarding to the empowerment as HE teacher. The outcome and conclusion of this study after going through the above process were as follows. When classifying the empowerment in 6 factors of class operation capability, influence, specialization, ethics, belief and self-regulation, the HE teachers recognized the ethics and self-regulation as high in the current empowerment, and had high demand on influence and class operation capability in the future empowerment. In other words, influence was to heighten the status and influence in HE education by participating in various local community activities, and the class operation capability was the capability to manage the class for bring out the interests of students, that these requirements could be considered as the expression of desire to recover the price for HE teachers as the professionals before students without the negative social recognition on the HE education. In the same context, most of the HE teachers recognized the execution of the education process as the situational practitioners, and for practicing better HE education at the actual classroom situation.
