The purpose of this study was to revalidate the 'Hospital Violence Attitude Scale-18 (HVAS-18) in clinical nurses'. 150 clinical nurses from three general hospitals in two cities participated in this study. Data were collected from March to April in 2017. The collected data were analyzed using factor analysis, Pearson correlation coefficients, and Cronbach's alpha. The final HVAS-14 consisted of fourteen items and four factors emerged, which explained 74.1% of the total variance. These four factors were labeled: Factor 1 (3 items) 'awareness' which explained 20.3%; Factor 2 (4 items) 'response' which explained 20.2%; Factor 3 (3 items) 'reaction' which explained 15.5%; and Factor 4 (4 items) 'result' which explained 15.4%. The internal consistency and intraclass correlation coefficient (ICC), as measured by Cronbach's alpha, were both .87, and the reliability of the subscales ranged from .78 to .86. The results of this study indicate that HVAS-14 is a useful, reliable and valid instrument to measure the hospital violence attitude of clinical nurses.

The purpose of this study was to examine the relationship of the critical thinking disposition of paramedic students to their satisfaction with hospital clinical practice and intention of recommendation. As for data analysis, the statistical packages SPSS WIN 20.0 and AMOS 20.0 were employed, and frequency analysis, factor analysis, multiple regression analysis and structural equation modeling were utilized. Besides, Cronbach alpha coefficients were calculated to check item internal consistency. The level of significance was all set at .05. A survey was conducted to collect data from May 12 to August 25, 2012, and the answer sheets from 305 respondents were gathered and analyzed. The critical thinking disposition of the paramedic students was found to have a significant impact on their satisfaction with clinical practice, and the hypothesis about that was accepted. Their critical thinking disposition was found to exert a significant influence on their intention of recommendation as well, and the hypothesis about that was accepted. Finally, their satisfaction with clinical practice was found to affect their intention of recommendation in a significant way, and the hypothesis about that was accepted. The findings of the study suggested that in order to nurture professional and competent paramedics, the content of clinical practice should systematically be managed on a regular basis, and prolonged research efforts should be directed into program development.

The purpose of this study is to develop the measurement of security needs satisfaction from users of electronic security system, to verify its validity and reliability, and by applying them, to examine the effects between the communities using this system. In 2008, the users of electronic security system in big cities in Seoul(Yong-San, Jong-Lo) and Gyung-Gi Do(Su-Won) for their convenience stores, jewelry shops, communication services, banks, government and public offices, etc. were arranged for a population and 262 of them were used for the final analysis by purposive sampling. This study yields following results. First, the validity of security need satisfaction from users of electronic security system is very high, which means the explanatory adequacy of environmental security need is the highest. Second, the reliability of security need satisfaction from users of electronic security system is very high, in which the reliability value(Cronbach's $\alpha$) of internal consistency is over .765. Third, the security need of electronic security system has the most effects on the group of bank workers. That is, through a close cooperative system between the bank and the service of electronic security system, the more keeping satisfied the environmental, bodily, physical security needs are, the less the in security of this group has. Informational security need has the most effects on convenient store group. It means the service companies of electronic security system offer more services at dawn time and make or supply all sorts of visual information system, which reduces insecurity of the convenient store group.

Objectives : To develop a physical functioning instrument for older adults living in the community. Methods : A representative sample of 979 people aged 65 years or over were interviewed in-person. Of these, 199 people also completed a detailed in-hospital examination. The scale items were selected based on the frequency of endorsement, along with the item-total and inter-item correlations. The associations of the scale with their physical performance and clinical examination were analyzed to evaluate the criterion-related validity. Construct validity was assessed using factor analysis, and internal consistency through Cronbach's alpha and item-total correlations. Test-retest reliability was measured by agreement between the household survey and the repeat survey at the in-hospital examination. Results : Initially, 23 items on the level of difficulty, ranging from no difficulty to an inability to complete a task, with the specific mobility and self-care tasks were included. Those with a high frequency of endorsement and a low inter-item or item-total correlations were excluded, resulting in a 10-item Physical Functioning (PT) scale. Equal weights were given to each item and a summated score was calculated. Significant associations were found between the PF scores and the physical performance, surrey and clinical data. The scale revealed a 2-factor (mobility and self-care) structure. Cronbach's alpha was 0.92 and the item-total correlations were in the 0.63 to 0.78 range. Pearson's correlations for the test-retest ranged between 0.56 and 0.61. Conclusions : The newly developed Physical Functioning (PF) scale showed good psychometric properties in older people. Further work, however, is needed to improve its sensitivity to discriminate higher levels of functioning, in addition to assessing its predictive value in detecting changes in health.

Background & Objectives : The Speech Handicap Index (SHI) is used to assess speech problem of head and neck cancer patients. The aim of this preliminary study was to evaluate the reliability and validity the Korean version SHI. Materials and Methods : Sixteen patients with oral cavity cancer and 26 normal control were participated in the study. Test-retest reliability of the Korean version of SHI was completed by 20 out of 42 subjects after 2weeks. Mann-Whitney U test was used to compare the Korean version of SHI scores between normal population and patients group. The relationship between the Korean version of SHI and diadochokinesis (DDK) was investigated using Spearman correlation coefficients. Results : The Korean version of SHI provided a high internal consistency (${\alpha}$=0.99) and test-retest reliability (Spearman rho 0.98). The mean SHI scores [total (T), speech (S), and psychosocial (P)] in normal population were 0.8 (T), 0.2 (S) and 0.4 (P), whereas those in patients group were 58.1 (T), 27.9 (S) and 27.0 (P) respectively. There were significant differences in total SHI score as well as in all of the sub-SHI scores between two groups. Moreover, significant correlation between the Korean version of SHI parameters (T, S, P) and sequential motion rate (SMR) were yielded in patients group. Conclusion : The Korean version of SHIwas reliable and valid. It can be useful as a supplementary clinical tool for diagnosing and measuring treatment efficacy of speech problems related to oral cavity cancer.

The purpose of this study was to describe the job retainment factors and the level of job satisfaction, and to identify the relationship between job retainment and the level of job satisfaction among the registered nurses working in hospitals. Four hundred eight registered nurses currently employed at 8 hospitals in Seoul were surveyed for the study. The 39 item, 5 point likert scale questionnare was developed by the researcher. The internal consistency of job satisfaction was. 86 and that of job retainment was. 90 in Cronbach's alpha test. The data sas collected from July 15 to July 30, 1993. The SPSS/PC+statistical program was used for data analysis. The descriptive analysis of the characteristics of the subjects, the level of job satisfaction and the job retainment factors was done. The relationship between the job satisfaction level and the job retainment factors was tested with. the Pearson Correlation Coefficient analysis, and thd differences of job retainment scores among the sample was tested with t-test and ANDVA. The results of the study were summarized. 1. The mean age of the subjects was 29.7 years, 41.7% of them were married. 71.1% of them were 3 years course graduates, 71.8% of them were staff nurses, and the mean duration of experience was 6 years. 2. The factors related to professionalism(3.43), society(3.31), and interpersonal relationship(3.29) were significant in job retainment. The maximum score was 5.0 Two other factors, personal(3.05) and organization(2.83) factors, also showed relatively high scores. 3. The factors to the job satisfaction showed similar pattern as job retainment: professionalism (3.47), society (3.33), finance(3.31), interpersonal relationship(3.02), and organization(2.72). 4. Society related factors(r=.7420, p<.00l) and professionalism(r=.7249, p<.00l) had high correlation with job retainment. Personal(r=.6372, p<.001) and organizational(r=.3597, p<.001) factors had moderate relationship to job retainment. Finance(r=.3597, p<.00l) had significant but weak relationship to job retainment. 5. Age, marital status, job position, departmental involvement, experience, and continuity of employment of the sample showed significant differences in job retainment. However, the period of job retainment, number of children, educational level, type of hospital, previous employment experience were not significant. 6. lndiviuals older than 40 years of age, who were married, who held the position of charge or head nurse position, who worked in central supply or nursing administration showed significantly high job retainment score. This research indicates that the professionalism is the most significant factor in job retainment. In order to retain more experienced nurses, it is important to improve the profesionalism among nurses.

Purpose - The objective of this study is to verify whether there are differences between Korean and Chinese consumers in the importance of the attributes such as shopping value and loyalty in social commerce. With the purpose of finding out these differences, the following questions are set up as research questions. First, will there be a difference between Korea and China in the importance of attributes of social commerce? Second, will there be a difference between Korean and Chinese consumers in shopping value? Third, will there be a difference between Korean and Chinese consumers in their loyalty? Research design, data, and methodology - The researchers collected data through self-administered questionnaires from Korean and Chinese consumers who had used social commerce within the past six months before answering the questionnaire. First, for social commerce users in Korea, comprising male and female university students in Chungcheong, a questionnaire was circulated. For social commerce users in China, university students within Beijing were surveyed. Responses to 336 questionnaires were used, excluding those with no answers or unreliable answers. Data coding and data cleaning were used. SPSS 18.0 was used. First, exploratory factor analysis is done to verify the validity of testing tools, and Cronbach's α coefficient is used to verify credibility. For factor analysis, the Varimax method is used. To verify the internal consistency reliability of each factor, the Cronbach's α coefficient is used to verify the credibility. Second, a T-test is done to verify differences between Korean and Chinese consumers for the importance of attributes. Third, ANOVA (Analysis of variance) is done to verify differences between Korean and Chinese consumers in shopping value and loyalty. Results - When Korean and Chinese consumers use social commerce, first, the importance of the attributes of social commerce is affected by four factors; playfulness and economic factors are more important to Korean consumers than Chinese consumers. As for informativeness factors, including product information and quality, and buyer comments, there was no confirmed difference between Korean and Chinese consumers. The convenience factor is more important to Chinese consumers than Korean consumers. Second, the factors affecting shopping value for Korean and Chinese consumers were hedonic shopping value and rational shopping value. To see the difference between Korean and Chinese consumers in shopping value factors, a t-test is conducted. As a result, in the rational shopping value factors of social commerce, Korean consumers scored higher than did Chinese consumers. These results were verified to be meaningful through statistics. In the hedonic shopping value factor of social commerce, Korean consumers scored higher than Chinese consumers. These results showed a significant difference. Third, loyalty in social commerce is higher for Chinese consumers than for Korean consumers. However, there is no difference in loyalty depending on sex. Conclusions - These results will hopefully be valuable and used in the future by Korean companies that wish to enter the Chinese social commerce market.

In this study the levels and influencing characteristics of maternal identity and self confidence for caring the baby were identified during the immediate postpartum period. 114 primiparous women who delivered vaginally normal baby participated in the survey from August 1 to October 31, 1996. SD scale was to measure maternal identity which consisted of 11 items for mother and 6 items for baby. Likert scale was to measure self confidence for caring the baby (38 items). Cronbach's alphas for evaluating internal consistency as follows : .86 for maternal identity and .96 for self confidence scale for caring the baby. The study showed these results : 1. Mean score of maternal identity(82.03 : 52.65 for mother, 29.38 for baby) was considered relatively low. 2. Mean score of self confidence for caring the baby(113.91) was considered relatively low. 3. There were significant influencing characteristics of primiparous to maternal identity : age(total ; F=3.53, p=.0329, for mother ; F=2.60, p=.0719, for baby ; F=3.12, p=.0481), prenatal infant care preparation(total ; t=2.31, p=.0306, for mother ; F=2.62, p=.0160), knowledge about infant care during the hospitalization(for baby ; F=3.94, p=.02222), colostrum feeding(total ; t=1.95, p=.0541, for baby ; t=2.71, p=.0080), frequency of breast feeding during the hospitalization(for baby ; F=3.91, p=.0228)and feeding type after discharge(for baby ; F=3.18, p=.0456). 4. There were significant influencing characteristics of primiparous to self confidence for caring the baby : routine husband support(F=6.09, p=.0031), prenatal infant care preparation(t=2.04, p=.0574), knowledge about infant care during the hospitalization(F=3.15, p=.0467), education of breast feeding during the hospitalization(t=-1.79, p=.0850). 5. Correlation between maternal identity and self confidence for caring the baby was r=.37608(p=.0001). This study implies that special education programs for primipara are needed. For the future, this study suggest that maternal role variables need to be monitored through the home visiting follow up. Also intervention programs related to prenatal care, discharge education, home visiting follow up need to be developed and then evaluated their effectiveness.

This study was carried out to develop a Korean language version of Zung's self-rating depression scale (SDS). The subjects consisted of 173 males and 161 females drawn from various groups of the general population by a cluster of sampling methods. In order to analyze the data on depression scores, Pearson's product moment correlation coefficient method was carried out, as well as reliability and factor analysis, by the SPSS/PC+ program. The results obtained were as follows: The mean average of the total depression scores were $40.60{\pm}8.66$ for the subjects. Thirty-seven subjects (11.1%) showed high depression scores of 50 or over. Test-retest reliability(coefficient r=0.82, p <0.001), internal consistency(coefficient r=0.84, p <0.001) were satisfactory. Factor analysis using oblique technique rotation yielded five factors. The items of confusion, indecisiveness, decreased libido, diurnal variation, and psychomotor retardation were scored higher by the subjects. The items of suicidal rumination, psychomotor agitation, constipation, irritability, and weight loss were scored lower.
