The subject of this research is the small-scale trade between South Korea and China (this trade is a so-called shuttle trade.) This research attempts to find the background to the emergence of the Sino-South Korean (cross-border) small-scale trade and the role of travel routes between the two countries. This research also aims to identify the development process of the bilateral small-scale trade by studying the scale of the small-scale trade and the organization of small-scale traders. Moreover, this research tries to discover the spatial characteristics of the interregional small-scale trade by reviewing the characteristics of traded goods; process of export and import and nodes of small-scale trade. To accomplish aforementioned purposes, the author discussed the relations between small-scale traders and maritime companies. The author also studied the internal change in the small-scale trade by focusing on the reinforcement of the regulation against the small-scale trade. Lastly, the author cited the case of the Soviet Union and middle-eastern Europe, which tremendously expanded the small-scale trades in the 1980s, in order to explain the growth of the Sino-South Korean small-scale trade.

The purpose of this study was to develop the first social work values scale in Korea. Its development would be expected to increase empirical studies on social work values. Based upon the literature review of social work values, the examination of codes of ethics as well as existing scales, and the comments from professionals in this field, 62 preliminary items were developed. Preliminary items were evaluated with a total of 521 social workers who were working in various fields of social work in Seoul and surrounding areas. A series of exploratory factor analyses were conducted to find out the optimal structure of the scale. After deleting 29 items with low factor loadings or being cross-loaded, the scale is composed of three factors with each factor having 11 items. Confirmatory factor analysis confirmed the factor structure of the scale obtained by exploratory factor analysis. The first factor was named autonomy, the second factor was named equality, and third factor was named paternalistic intervention. Each component of the social work values scale is found to be reliable and valid.

A large-scale IS development project takes a long time, thus its project manager needs to be more careful on risk management. In particular, appropriate cutover decision making is critical in large-scale IS development projects because the opening of the large-scale IS significantly impacts the organization. Regardless of its importance, cutover decision making in conventional IS development projects has been done in a quite simple way. Conventional cutover decisions have been made by considering just whether the new IS operates or not from the system, application, and data implementation perspectives. However, this approach may lead to unsatisfactory performance or system failure in complex large-scale IS development. Under this background, we propose a new framework for cutover decision making on large-scale IS projects. To validate the applicability, we applied the framework to a core banking system development case. The case study shows that our framework is effective in proper cutover decision making.

Purpose: This study was conducted to evaluate the effectiveness of the maternal role education program for primiparas in mother-infant interaction, childrearing environment, and infant development. Method: A Non-equivalent control group time-series design was used. For the intervention group, programmed parenting education focusing on mother-infant interaction, home environment for infant development, and parent counseling and support was provided via home visits or telephone for twelve months. Result: Significant differences were found in the mother-infant interaction feeding scale at one and three months, but no differences were found in the teaching scale at six and twelve months between the intervention and control groups. Also, the difference in childrearing environment (HOME) between the two groups was significant at three, six, twelve months. In addition, the intervention group showed higher GQ in the Griffiths mental development scale at three and six months. In multiple regression analysis, 22.6% to 43.6% of infant development was explained by HOME, mother-infant interaction, and previous development. Conclusion: The maternal role education program proved to be effective in promoting mother-infant interaction, organizing the childrearing environment, and fostering infant development.

This study was aimed at developing a scale to evaluate Korean home environments for infants and toddlers for the purpose of being used by teachers caring for infants and toddlers. The subjects of this study were 250 mothers of 0- to 2-year-olds. Mean, SD, $x^2$, Cramer's V, factor analysis, Pearson correlations, Cronbach's ${\alpha}$ were calculated in order to analyze the outcomes of this study. As a result, 38 items of the scale were found to be satisfactory in terms of item distribution and item discrimination. Four factors with 21 items were extracted from the factor analysis : 'developmental stimulus', 'responsivity', 'encouragement of verbal interaction', and 'arrangement of daily routines'. Our analysis of the correlation of this scale with SES, HOME, and children's developmental outcomes showed acceptable concurrent validity. Internal consistency of this scale was high. These results identify this scale as a valid and reliable measure of the Korean home environment for infants and toddlers.

Purpose: The purpose of this study was to develop and evaluate psychometric properties of the instrument, Resuscitation Self-Efficacy Scale for nurses. Methods: This was a methodological study for instrument development and psychometric testing. The initial item pool derived from literature review and experts resulted in 30 items linked to resuscitation self-efficacy. A convenience sample of 509 Korean nurses from eleven academic teaching hospitals participated in a survey to examine psychometric properties of the scale. To examine construct validity, exploratory factor analysis and known-group comparison were used. Cronbach's coefficient alpha was used to determine the scale's internal consistency reliability. Results: The final scale included 17 items with four-component structure termed 'Recognition', 'Debriefing and recording', 'Responding and rescuing', and 'Reporting'. These four factors accounted for 57.5% of the variance. Each subscale and the total scale demonstrated satisfactory internal consistency: .82; .88; .87; .83; and .91 respectively. Experienced nurses reported significantly higher self-efficacy mean scores in both total and subscales compared to new graduate nurses. Conclusion: The Resuscitation Self-Efficacy Scale for nurses yields reliable and valid results in appraising the level of resuscitation self-efficacy for Korean nurses. Further study is needed to test and refine the scale.

Purpose : The objective of this study was the development and validation of a scale to measure the self-care of patients with chronic obstructive pulmonary disease(COPD) in Korea. Method: Self-care scale was developed based on the self-care activities patients had to carry out in order to manage their COPD. The original scale contained 34 items rated along a five-point Likert scale and was reviewed by 18 professional nurses and 10 Korean patients with COPD for content validity. Subsequently, patients with COPD were asked to complete this 23-item scale and further tests were done with the 125 useable responses. Result: Factor analysis identified eight factors-'maintaining a clean air way', 'taking medication', 'support from family', 'preventing infection', 'managing symptoms', 'breathing exercising', and 'taking in nutrition'. The internal consistency of the total scale was Cronbach's α=0.7226. These eight factors explained 60.8% of total variance. There was correlation among Korean Self-Care Scale score, administration level, and knowledge level but there was no correlation to patients' satisfaction with medical services. Conclusion: The 23 item questionnaire positively identified 8 areas defined important for COPD patients. Further studies are required to see how these can be integrated into patient education.

Purpose: The purpose of this study was to develop a scale to measure professionalism of clinical nurses and evaluate the reliability and validity of the scale. Methods: DeVellis's scale-development eight steps were applied. The initial items were developed through a literature review and discussion with investigators, and the content validity was verified by seven experts. The data were collected from 250 hospital nurses for exploratory factor analysis and 217 hospital nurses for confirmatory factor analysis. Exploratory and confirmatory factor analyses were utilized to assess the construct validity. Cronbach's ⍺ was used to test the internal consistency reliability. Results: The results of the exploratory and confirmatory factor analyses showed that the scale comprised four factors: professional skill(eight items), sense of ethics (five items), knowledge-seeking activities (four items), and autonomy(three items). The four-factor structure was validated (x 2 =600.85 p<.001, GFI=.88, CFI=.84, RMSEA=.07), and Cronbach's ⍺ for the total scale was .84. Conclusion: The study results showed satisfactory reliability and validity of the professionalism measurement scale for clinical nurses. This scale has potential as an appropriate instrument for measuring clinical nurse professionalism.

Life safety awareness level diagnosis is necessary for customized safety education and continuous safety awareness. As the starting stage of safety education for each life cycle, a scale that has verified the reliability and validity of high school students' life safety awareness has not yet been developed. In this context, the purpose of this study is to develop and validate the life safety awareness scale of high school students and to analyze interindividual differences. Questionnaire data was collected from April to June 2022 from 834 students in the first, second, and third grades of high schools in △△ city in Jeollabuk-do. A final 25-item scale was developed using the preliminary survey, preliminary test, the main test, descriptive statistical analysis, and exploratory and confirmatory factor analysis. This scale consists of four sub-factors: 'safety prevention', 'safety knowledge', 'safety preparation', and 'safety protection'. Good reliability and validity were verified by analysis of content validity and construct validity. The generalizability of the scale was verified by crossover validation between the search group and the crossover group. Based on the interindividual differences analysis, although there was a difference between genders in life safety awareness, there was no difference by grade level and academic achievement. This study is significant in developing the first valid scale that can measure high school students' life safety awareness and providing the necessity and rationale for life safety education by life cycle considering individual gender differences.
