  • The purpose of this study was to develop a standardized scale to measure consumers' motivation to purchase based on a self-determination theory. A preliminary 27-item scale was developed through literature review, diary analysis, and FGI. A questionnaire survey was conducted among 1,000consumers on internet using the preliminary scale. Then a series of tests, such as test-retest, item analysis, item-to-total correlation, Cronbach's reliability coefficient, and factor analysis, were conducted using the survey data. The final scale with21 items was constructed in the end. The Purchase Motivation Scale for Consumers consisted of five factors: (1) external motivation, (2) introjected motivation, (3) identified motivation I: self-respect, (4) identified motivation II: pursuit of harmony, and (5) internal motivation.

  • The purpose of this study was to develop a standardized scale to measure consume's impulse purchasing in internet shopping mall. As internet shopping is expanding rapidly, the consumer's impulse purchasing in the internet shopping is also increased. A preliminary 26-item scale was developed through a literature review. 1230 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying the academic data on the consumer's impulse purchasing but also understanding the consume's basic behavior patterns in internet shopping mall. Then A series of tests, such as test-retest, item-to-total correlation, Cronbach's reliability coefficient and factor analysis, were conducted using the survey data. The final scale with 20-items was constructed in the end. The consume's impulse purchasing in internet shopping mall Scale for Consumers consisted of 4 factors.

  • The purpose of this study was to develop a standardized scale to measure consumption self-regulation. A preliminary 38-item scale was developed through a literature review. One thousand-twelve consumers responded to an online survey using the preliminary scale. A series of tests, such as test-retest, item-to-total correlation, Cronbach's reliability coefficient and factor analysis, were conducted using the survey data and a final scale comprising 30 items was then constructed. The consumption self-regulation scale consisted of four factors: (1) impulse control, (2) gratification delay, (3)self-reliance, and (4) self-management.

  • This paper has derived some problems relating to the use of letters of intent which are common occurrence in the international contracts after considering its nature and legal issues. As reviewed before, some problems may occur when a party has documented a stage in the negotiations by letters of intent. Such documents may well explicitly spell out if, and to what extent, the parties should be bound by what they have already agreed or to carry on negotiations in order to reach the final contract. But if the documents are silent, some problems would arise. Contracting parties are therefore well advised to spell out if, and to what extent, they should be bound by such preliminary agreements. Here again, it might be prudent to explicitly set forth that the parties should not be bound until there is a final written contract signed by authorized representatives of the parties but that they shall abstain from such measures which may defeat their stated objective to reach final agreement, for example, by diminishing the value of performance under the contemplated contract.

  • The purpose of this study was to develop a standardized scale to diagnostic life planning in late adolescence. A preliminary 32 item scale was developed through a literature review & a survey. 896 people responded to an online survey using the preliminary scale. A series of test, such as test-retest, item-to-total correlation, factor analysis and Cronbach' ${\alpha}$ reliability were conducted using the survey data and a scale comprising 31 items was constructed finally. The diagnostic scale for life planning in late Adolescence consisted of seven factors : (1) complete growth minds (2) life- plan (3) variety experiences (4) close relationships (5) management of healthy body (6) practical finance-plans (7) active preparation of future job. The scale is useful as a guideline for managing life of the late Adolescence. And it is helpful to them to make plan for the better life.

  • The purpose of this study was to develop safety competences, a set of behavioral indicators of each competence and measuring methods of behavioral indicators for preventing human error of nuclear power plants(NPPs). The safety competences and behavioral indicators were derived from the five steps consisted of derivation of preliminary competence items through literature review, content analysis, interview(FGI, BEI), examination of content validity and decision making of final indicators. The results showed that 13 core safety competences and 35 behavior indicators were derived finally. In addition, the methods of measuring safety competences or behavioral indicators such as Behaviorally Anchored Rating Scale (BARS), Behavior Observation Scale (BOS) were developed and suggested.

  • Appropriate management of the finish works in construction project is one of most important activities that must be conducted considering the total duration of the project. Masonry work is a fundamental process that is performed in the preliminary steps of finish works. However, it has been investigated that the analysis of delay factors affecting masonry work has been neglected in the domestic construction site. Therefore, this study deducts delay factors affecting masonry work by literature review and survey on site engineers and labors. This study has been conducted as a preliminary step of developing a construction project interference management system which is expected to suggest objective information for the decision making in construction sites.

  • Construction robotics is rapidly forming a market in conjunction with the development of sensing and artificial intelligence technologies. The layout work for accurately constructing the shape and dimensions of the building frame requires high accuracy and precision, and is one of the high demands for productivity and quality improvement through construction automation. Thus, as a preliminary study, we derived the elemental factors and performance requirements for developing an automated layout robot. In addition, alternatives on driving and marking units were investigated based on literature review and practioner's interview. The result of this study will be used as a basic data for the layout robot design.

  • Objectives: The aim of this study is to investigate the core emotion assessment instrument based on the Chiljeong. Methods: We searched for a literature review of oriental medicine and established the operational definition. Based on the existing psychological scale measurement, we selected the items and analyzed the reliability through a two-step preliminary study. Results: 1) Through the analysis of reliability after the two-step preliminary study (first: 170 items, n=63, second: 152 items, n=42), we had excellent internal consistency (Cronbach's alpha > 0.70) as well as good test-retest reliability (>0.70). Thus, we demonstrated that this scale had reliability. 2) Analyzing the correlation of each emotion, we had a comparatively strong positive-correlation (>0.6), except for Hui, and found a particularly high correlation of Sa, U and Bi. Conclusions: We developed the final 141 items of the core emotion assessment instrument through the two-time preliminary study. In the future, the main study on the clinical and non clinical groups of various ages should be continued.
