The purpose of this study was the investigation of theoretical and empirical relationships between Piagetian and psychometric assessments of intelligence. Specifically, the factor structure of Piagetian-type scales, the relationship between Piagetian scales and psychometric intelligence tests, and differences in the factor structure of Piagetian and psychometric assessments of intelligence were studied. The subjects of this stuby were 70 children (35 boys and 35 girls) in the 1st grade of an elementary school in Seoul The Piagetian-type scales and the K-WISC were administered individually, and the General Intelligence Test was administered to groups of children. Statistical analysis of the obtained data consisted of the SPSS Computer program including factor analysis and Pearson's product moment correlation coefficient. The Piagetian-type scales were found to consist of three factors, which accounted for 55 percent of the total common-factor variance. Factor-I was a factor indicating "conservation". Factor-II was a factor indicating "moral judgements". Factor-III was a factor indicating "classification and identity". Correlations between subtests of psychometric tests and Piagetian scales were relatively low or moderate. Relations between IQs assessed by the psychometric tests and Piagetian scales were also relativeyly low or moderate. Eight factors were extracted from the joint factor analysis of psychometric intelligence tests and Piagetian scales, and they accounted for 67 percent of the total common-factor variance. Factors-I, II, III, and V consisted of subtests of psychometric assessments, and Factors-IV, VI, VII and VIII were composed of Piagetian scales. Factor-I was a factor for "reasoning ability based upon language". Factor-II was a factor for "performance ability". Factor-III was a factor for "grouping ability". Factor-IV was a factor for "conservation". Factor-V was a factor indicating "symbol and language usage ability". Factor- VI was a factor indicating "moral judgments". Factor-VII was a factor indicating "length consevation". Factor-VIII was a factor indicating "classification and identity".

A programming education has favorable influence on creative / logical thinking and problem solving ability of students. However, students typically have to spend too much effort in learning basic grammar and the usage model of programming languages, which negatively affect their eagerness in learning. In this respect, we proposed to apply the 'Scratch' using the Creative Problem Solving(CPS) Teaching Model; Scratch is an easy-to-learn and intuitive Educational Programming Language(EPL) that helps improving the problem solving ability of the class. Then we verified the effect of Scratch EPL through the design of both pretest and posttest for a subject group. In summary, the CPS based Scratch EPL was shown to significantly improve the problem solving ability and also help them develop favorable attitude in programming.

The purpose of this study was to investigation the variables that affected the generational transmission of household work form mothers to their married daughter. The subjects were 415 married daughters and their mothers living in Seoul and metropolitan areas. Statistical techniques used for this study included descriptive statistics and multiple regression analysis. The results of this study were as follows : First, married daughters; value of household work was significantly affected by total periods of marriage of daughters, daughter's perceived similarity to their mothers' household work. Second, married daughters' preference for household work was significantly affected by mother's occupation (managerialㆍprofessional), mother's perceived similarity, daughter's experience of living with mother-in-law, daughter's sex-role attitude, and daughter's perceived similarity. Third, married daughters' ability to do household work was significantly affected by total periods of marriage for mothers, mother's perceived similarity, and daughter's perceived similarity. Fourth, married daughters' standard of household work was significantly affected by mother's perceived similarity, daughter's occupation (techniciansㆍclerk), daughter's monthly income, and daughter's perceived similarity. Fifth, married daughters' usage level of home equipments was significantly affected by mother's birth order, mother's education, mother's occupation (managerialㆍprofessional), daughter's birth order, daughter's education, and daughter's monthly income. Sixth, Mother related variables had greater power than daughter related ones in explaining daughters' values and preference for household work value and preferences and usage of home equipments. In conclusion, married daughter's consciousness and performance of household work were significantly influenced by their mothers. It was especially so in daughter's usage level of hoe equipments. Accordingly, the results of this study support the existence of generational transmission of household work from mothers to their married daughters with regard to its consciousness and performance. Findings of this study have implications for counsellors, practitioners and educators.

This study examined the awareness, satisfaction, and usage patterns of 257 elementary school teachers for food labeling in Busan. The survey was conducted from April 15 to June 20, 2020, by questionnaires. The perception degree of food labeling was higher in female teachers than in male teachers and did not differ significantly among age groups. The score of the understanding degree was highest in their 20s and lowest in their 30s. The degree demand in their 50s was higher than in their 30s and 40s. The reliability degree in their 20s was higher than that of those in their 40s and 50s. The verification degree and satisfaction degree did not differ significantly with age or gender. The primary reason to check food labeling was 'to confirm harmful additives (31.9%)'. Among those in their 20s and 30s, the major reason for reviewing nutrition labeling was 'nutrient', while it was 'health improvement' was most important in those in their 40s and 50s. Of the subjects, 31.1% reported that the reason for the difficulty in understanding the label was 'various forms and the small letters'. The demand for the content was highest in trans fats. Apporximately 32.3% of the teachers were educated for food labeling; 42.4% of them taught food labeling, and 62.7% of them recognized the necessity of food labeling teaching. A correlation was observed between the demand for food labeling and understanding (r=0.586). Therefore, preparing education programs for teachers according to gender and age group and developing food additives-related programs will be necessary for strengthening the teachers' ability to manage their dietary life and educate students.

Purpose: To investigate whether the long-term use of a cane induces pain in the unaffected lower limb of stroke patients. Methods: A total of 107 stroke patients with chronic hemiparesis were recruited in this study and classified into two groups; a cane-use group (n=49) and non-cane-use group (n=58). The existence of pain in the unaffected lower limb was assessed on a visual analog scale in the hip, knee, and ankle joint, and the University of Alabama pain behaviors scale (UAB pain behavior scale) used to measure the intensity of pain. In addition, the Motricity Index (MI) was tested in the upper and lower extremities. Results: The proportion of pain in each joint of the lower limb was significantly higher in the cane-use group, compared to the non-cane-use group (p<0.05). In addition, significant differences were observed on the UAB pain behavior scale between the two groups. The lower MI score was significantly lower in the cane-use group, compared with the control group. However, no difference was observed in MI scores of the upper limb between the two groups. Conclusion: These findings reveal that long-term cane usage can induce pain in the unaffected lower limb of stroke patients. We suggest careful consideration when prescribing a cane, depending on functional ability in hemiparetic patients, and recommend continuous evaluation for pain in the affected lower limb.

By using the raw data of the 2015 Agriculture, Forestry and Fishery Consensus that surveyed the farmers engaged in agriculture, forestry and fishery in 2015, this study investigated the effects of the characteristics of the farms in Gangwon-do on the utilization of the digital devices, which was classified into computers usage only, smartphones usage only, both computers and smartphones usage, and no digital device usage. This study used the Multinomial Logit Model for the above purpose. Moreover, the IIA(Independence of Irrelevant Alternatives) method of the Multinomial Logit Model was analyzed to be suitable. Upon the result of the analysis, when all the other variables were constant in the average, the probability of choosing both computers and smartphones increased by 0.02% as the family member living together with the farm owner increased by 1 person. In addition, the farms with agricultural machineries have 0.03% increased probability of using smartphones to sell their agricultural products, when compared with the farms without agricultural machinery. Moreover, for the farms with high sales profit of the agricultural products, the probability of using computers and the probability of using smartphones increased by 0.04% and 0.01%, respectively, and the probability of using both computers and smartphones increased by 0.02%. On the other hand, for the farms affiliated with the agricultural organization, the probability of using both computers and smartphones increased by 0.17%, and the probability of using only smartphones and the probability of using only computers increased by 0.16% and 0.15%, respectively. In case of selling to the National Agricultural Cooperative Federation(NACF), the probability of using smartphones increased by 0.11% if all other variables were to be constant in the average. In particular, the farms participating in the agriculture-related industries have 1.09% increased probability of using computers, have 0.92% increased probability of using smartphones, and 0.85% increased probability of using both computers and smartphones. Therefore, the implications suggested based on the results of the analysis are as follows. First, the farms' choices of the digital devices are made independently. Hence, the future agricultural industry business platform establishment should necessarily consider the types of farms' choices of the digital devices in the future. Second, since the usage of digital devices has a generally positive influence on the farm household income, digital education to improve farmers' ability to use the digital devices should be urgently provided in order to improve the farm household income in the farms in Gangwon-do. Third, because the digital devices used to sell agricultural products differ depending on the age of the farm owner, it would be desirable to target the younger generation of the farm owners rather than establishing the agricultural industry business platform for the farms in the aged farm villages. Fourth, it would be advisable for the future agricultural business platform to consider the characteristics of agricultural products sales source.
