  • Scale scores for cognitive domains have been used as an important indicator for both academic achievement and clinical diagnosis. For example, in education, Cognitive Abilities Test (CogAT) has been used to measure student's capability in academic learning. In a clinical setting, Cognitive Impairment Screening Test utilizes items measuring cognitive ability as a dementia screening test. We demonstrated a procedure of generating cognitive ability test items similar as in CogAT but the theory associated with the generation is totally different. When creating cognitive test items, we applied automatic item generation (AIG) that reduces errors in predictions of cognitive ability but attains higher reliability. We selected two cognitive ability test items, categorized as a time estimation item for measuring quantitative reasoning and a paper-folding item for measuring visualization. As CogAT has widely used as a cognitive measurement test, developing an AIG-based cognitive test items will greatly contribute to education field. Since CLASS is the only LMS including AIG technology, we used it for the AIG software to construct item models. The purpose of this study is to demonstrate the item generation process using AIG implemented within CLASS, along with proving quantitative and qualitative strengths of AIG. In result, we confirmed that more than 10,000 items could be made by a single item model in the quantitative aspect and the validity of items could be assured by the procedure based on ECD and AE in the qualitative aspect. This reliable item generation process based on item models would be the key of developing accurate cognitive measurement tests.

  • This study's aim was to analyze the effect of a project activity based on role play on 5-year-olds' mathematical ability. The participants of this study were 56 5-year-olds from two educational institutions for young children located in two metropolitan cities in Korea. The experimental group (n=28) participated in a project activity based on role play, while the comparative group (n=28) did not. The "Mart Play" project activity based on role play was developed emergently by the children and teachers of the experimental group. The children's mathematical ability was measured before and after the experiment. The data were analyzed using t-test and ANCOVA. As a result, the project activity based on role play had an effect on the improvement of 5-year-olds' mathematical ability generally, but not on their measurement ability.

  • At present, the overall water resources monitoring ability in China is weak since there is an absence of a sound monitoring system and comprehensive monitoring information. In addition to the problem of weak management ability in monitoring, measurement and information, it can hardly meet the need of implementing the strictest management system of water resource and also restricts the practice of the system to some extent. The production states the necessity of further development of water resources monitoring ability and points out the concept of "One Country, One Account" for constructing water resources information. There is an analysis on the demand on further development of water resources monitoring ability and profound discussion about the strategies for supporting "three red-line" management.

  • The purposes of this study were to investigate whether the program of health promotion and follow up feedback by periods could improve physical fitness related to work ability of the middle-aged and aged workers. Subjects were composed of two groups; workers aged below forty five and forty five and over who had measured their health-related physical fitness twice for 2 years (2006 & 2007) through the program of health promotion operated by Korea Occupational Safety & Health Agency. Paired t-test was used to evaluate the difference between the first measurement and re-measurement of health-related fitness which was operated after six to twelve months from the first one. We used 0.05 level for statistical significance. The results of this study were as follows. All measurement items including body fat ratio(%), $VO_2max$, grip strength, sit-up, and trunk flexion were significantly improved in both groups. The improvement(%) of $VO_2max$, grip strength of workers of forty five and above was lower than those of workers of below forty five. Servicing the program of health promotion and follow up feedback by periods may help workers' improvement of health-related physical fitness related to work ability.

  • Purpose : This study attempts to assist stroke patients lead independent daily life movements by providing basic data for stroke patients' successful rehabilitation program and understanding the relationship between health beliefs of stroke patients and their guardians, and patients' rehabilitation performance level and daily life movement fulfillment ability. Methods : 23 stroke patients receiving treatments at rehabilitation specializing hospital after getting diagnosed with a stroke, along with 23 guardians were selected as research subjects, and health belief was measured by modifying supplementing Byun Young-Hee(2002)'s health belief measurement tool for leg movement disorder patients. Research findings revealed the following relationship between health beliefs of stroke patients and their guardians, and patients' rehabilitation performance and daily life movement fulfillment ability. Results : The patients group's initial MBI score was $33.13{\pm}3.46$, and measurement after four weeks was $38.43{\pm}3.47$. As health beliefs got stronger, MBI score increased significantly(p<.05). Correlation analyses of factors that affect rehabilitation attendance rate showed that perceived susceptibility, seriousness and usefulness were statistically significant, and perceived disability was not statistically significant(p<.05). Guardians' health belief index(susceptibility, seriousness, usefulness, disability) had no correlation with rehabilitation attendance rate. Conclusion : In order to increase daily life movement fulfillment ability of patients who are being treated with stroke, health beliefs must be raised to increase changes in daily life movement fulfillment ability. Therefore, it is believed that managing programs that can increase health beliefs of stroke patients can allow patients obtain positive health beliefs, further increase rehabilitation performance rate of stroke patients as well as independent daily life ability.

  • The presence of imprecise measurement may seriously affect the efficiency of process control and production cost. A cost model is derived to determine the design parameters of the economic asymmetric $\bar{X}$ and S control charts including measurement errors. The effects of imprecise measurement on the performance of the economic asymmetric $\bar{X}$ and S control charts and production cost are examined for the case where the process mean and process standard deviation may change. Application of the proposed control charts is demonstrated through an example. Numerical examples illustrate the effects of imprecise measurement on the design parameters of the proposed control charts. It shows that the imprecision measurement may seriously affrct the ability of the proposed control charts to detect process disturbances quickly, change the sampling frequency, and increase the production cost compared to the control charts excluding measurement errors.
