  • The purpose of this study was to development of the 'convergence motive' scale for interdisciplinary knowledge fusion. Based on results from literature review, this study clarifies a theoretical ground for 'convergence motive'. Initial items to measure this concept were verified by content analysis and then finalized. After a pilot test done with 568 college students, gathered data were analyzed by item selection and exploratory factor analysis to verify their validity. Next, the main test implemented with 1,211 college students was analyzed with exploratory factor analysis using the method for rotation based on maximum likelihood analysis and direct oblimin for validating the final items to measure 'convergence motive'. As a result, the scale for 'convergence motive' consists of 43 items to measure the following four factors: collaboration to identifying and solving problems, challenge of a new perspective, communication for convergence, cohesion for convergence. Construct validity and criterion-related validity were performed at last to check this scale's theoretical construct. In conclusion, this study concluded that the scales for convergence motive could be generalized and applicable to other samples.

  • This paper presents a weight adjusted association rule mining algorithm (WARM). Assigning weights to each strategic factor and normalizing raw scores within each strategic factor are the key ideas of the presented algorithm. It is an extension of the earlier algorithm TSAA (transitive support association Apriori) and strategic importance is reflected by considering factors such as profit, marketing value, and customer satisfaction of each item. Performance analysis based on a real world database has been made and comparison of the mining outcomes obtained from three association rule mining algorithms (Apriori, TSAA, and WARM) is provided. The result indicates that each algorithm gives distinct and characteristic behavior in association rule mining.

  • The purpose of this study was to develop an instrument for measuring elementary school students' environmental literacy. The process of instrument development was four phases. The first two phases involved defining the domain of the construct, writing an initial pool of 55 items, and reviewing the items for revision and deletion. These steps were taken to provide the evidence of content-related validity, and to reduce a number of items. The third phase was, through item analysis, to determine the most appropriate items for the environmental literacy for the elementary school students. For the forth phases, the fifth and sixth students in elementary school participated in this survey. To examine the reliability and validity of environmental literacy for the elementary school students, internal consistency estimate, and factor analysis were used. The results of this study were summarized as follows; Firstly, thorough factor analysis, we developed Environmental Literacy Instrument for the elementary school students, consisted of total 41 items (knowledge 8 items, emotion 11 items, skill 10 items, and behavior 13 items); Secondly, Cronbach's alpha was .783 for knowledge, .832 for emotion, .866 for skill and 8.61 for behavior.

  • The purpose of this study was to develop a scale for evaluation of premarital preparation. The subjects were 412 married couples(196 males and 216 females) who had been married for 1-37ears. They were selected from Seoul, Incheon, Daejeon, Gwangju, Pusan, and DaeGu. The questionnaire was composed of 82 items. The data was analyzed by frequencies, percentages, factor analysis, Pearson's r, and Cronbach'$\alpha$. The major findings were as followings; 1. The 54 items of 82 items scale were selected through item discriminant method. The discriminant coefficients of the items(Cromer's V ranged from .33 to .68. 2. The 7 factors that were extracted from the factor analysis explained 42% of premarital preparation. The subscales were labelled as rearing child$.$financial management role division, maturity, understanding each other$.$love$.$sex, views about marriage, understanding his/her family and friends, capacity of communication and conflict resolution, and independence from parents. The criterion validity of this scale was assessed by the correlation between this premarital preparation scale and marital stability. All coefficients were significant(ranged from r=.10 to .44, p<.01, p<.001). 3. The internal consistency of this scale was acceptable(Cronbach's $\alpha$=.91).

  • The purposes of this study were to develop a job stress measurement tool and to identify the job stress according to the characteristics of worker and work condition at the small and medium-sized plants. Data were collected through face-to-face survey for April-May, 1997. Subjects were 180 workers at 36 small and medium-sized plants located near Seoul. Data were analyzed by item analysis, factor analysis, and ANOVA. The results were as follow : 1, Number of items of job stress measurement were 33 and Cronbach's $\alpha$ was .9262 except 13 items with low values of Cronbach's coefficient. Factor analysis was done in order for construct validity and 8 factors were extracted and cumulative percent of variance was 65.6%. 2. The job stress scores of male, the younger, 2-shift workers, and over-time workers were significantly higher than those of female, the older, 1-shift workers, and 48 hour workers per week. 3. There were no significant difference between job stress scores and the groups by number of worker, and the types of manufacturing. The stress measurement tool is valid and very reliable to measure worker's stress. Furthermore, the job stress managent program for health promotion of the workers at the vulnerable work condition is needed more and more.

  • Recently, most of countries in the world are investing huge amount of capital for the infrastructure of logistics and trying to gain dominating position in logistics. To play the role of important hub in logistics, an efficient, flexible, and fault-tolerant transportation process should be developed. Minimization of transportation cost and timely deliveries in the unpredictable environment are a few of the important issues in logistics. This study suggests a way of transporting goods to destinations at the minimal cost and with the minimal delay by optimally allocating transporting resources. Various attributes in transportation such as due date, priority etc. are also considered. Appropriate transporting resources for each work item is selected by calculating the weighted sum of the cost factor and the delay factor assuming that initial sequences of work items are given. A policy to reallocate transporting resources is also suggested when work items or transporting resources are added or deleted because of accidents or disturbances. This policy provides adaptability to the allocation methodology which enables the system to cope with changing environment by controlling various attributes in transportation. Genetic algorithm is used for this approach.

  • Spirituality has been found as a factor that may influence an individual's health and response to illness and dying. The purpose of this study was to assess the reliability and validity of the Korean version of the Howden's Spiritual Assessment Scale(SAS). The SAS was developed based on the attributes of spirituality and constructed with 28 items, 4 subscales. The translation involved four steps : translation into Korean, checking agreement, back translation into English, and arriving at a consensus. Psychometric evaluation was done on 222 nurses from five hospitals. All responses were voluntary and anonymous. The Cronbach's alpa coefficient for internal consistency was .928 for the total 28 items and .700${\sim}$.805 for subdimensions. Item- total correlations ranged from .36${\sim}$.68. Principal Component Factor Analysis with Varimax Rotation yielded four factors with four or more items each loading at .40 or higher. These factors explained 51.3% of the total variance. The items clustered in this study were almost identical with initial scale. There was positive correlation(r=.648, p=.0001) between SAS and Ellison & Paloutzian's Spiritual Wellbeing Scale and negative correlation(r=-.418, p=.000) with Pines' Burnout Scale which indicate convergent and discriminant validity. In conclusion, this tool can be effectively utilized for assessing spirituality in Korea.
