This study investigated the differences in smart speaker users' loneliness, social disconnection, and attachment, frequency of daily speaker usage, and anthropomorphic behavior depending on the level of smart speaker anthropomorphism. A total of 320 users participated in an online survey. Results showed significant differences between the high anthropomorphism group and the low anthropomorphism group in their level of loneliness, social disconnection, anxiety attachment, frequency of daily speaker usage, and anthropomorphic behaviors. However, no significant difference in avoidance attachment between the two groups was found. The findings imply that interaction design can possibly enhance positive social interaction with smart speakers.

본 연구에서는 2016년도 말 현재 사학연금의 연금부채 규모를 추정하고 이를 기반으로 연금기금의 적립수준을 평가한다. 연금부채 산정방식으로는 보편적으로 적용되고 있는 예측단위적립방식과 더불어 가입연령방식을 적용하였다. 예측단위적립방식은 발생주의 회계원칙에 가장 적합한 재정방식인 반면, 가입연령방식은 연금제도의 지속을 전제로 하는 공적연금제도의 특성을 가장 잘 반영할 뿐만 아니라 안정적 제도운영을 위한 비용 수준 역시 확인할 수 있도록 해주는 장점이 있기 때문이다. 예측단위적립방식과 가입연령방식의 적용 시 연금부채는 각각 114.4조원과 115.1조원으로 나타났으며, 연금부채 대비 적립기금 비율인 적립률은 각각 14.3%와 14.2%로 산출되었다. 또한 가입연령방식의 연금부채평가를 위해 산출한 가입연령별 수지상등 표준부담률은 현재 사학연금제도에서 적용하고 있는 부담률을 크게 상회하는 것으로 파악된다. 이러한 분석 결과는 연금재정의 지속가능성 측면에서 그 미래가 낙관적이지 못하며 이를 개선하기 위한 방안이 강구되어야 함을 시사한다. 다만 연금부채를 통한 재정진단 시에는 공적연금제도로서 사학연금이 지니는 특수성을 고려해야 한다. 우리나라의 공적연금은 제도의 도입목적에 따라 가입자의 부담수준에 비해 후한 급여체계로부터 시작되었기 때문이다. 따라서 민간 부문에서와 유사한 수준의 기금적립은 기대하기 어려울 수밖에 없다. 이를 감안하지 않을 경우 상기의 분석결과는 노후소득보장이라는 본연의 목적보다 재정안정화 수단만을 위한 근거로 이용될 수 있음에 유의해야 한다.

The aim of this study is verifying the effects of chatbot's error types and structures of error message on attitude, behavior intention towards the chatbot and perceived usability of the chatbot. The error types of chatbot are divided into 'experience' error and 'agency' error, which set different expectancy level, according to mind perception theory. The structures of error message were either unstructured condition composed of error specification only or structured condition composed of apology, explanation and willingness of improvement. It was found that score of perceived usability was higher in experience error condition than agency error condition. Also, all three scores of dependent variables were higher in structured error message condition than unstructured error message condition. Furthermore, expectation gap of experience didn't predict the dependent variables but expectation gap of agency predicted all three dependent variables. Finally, the tendency of interaction effect between the error type and the structure of the error message on expectation gap of agency was observed. This study confirmed the mitigating effect of structured error messages and the possibility that these effects may vary by the type of error. The result is expected to be applicable to design of error coping strategies that enhance user experience.

This paper compares two indicators, economic development and social condition, to find a better way to measure the level of social welfare development. The results show that social condition is more adequate indicator than economic development. The social condition has high correlation with the development of social welfare in all the 78 countries as well as in five groups of countries when the economic development is controlled. The comparison of two indicators reveals important findings. Among other things, the higher the level of social condition compared with economic development, the larger the social welfare expenditure. This tendency is particularly strong among the western European countries and former socialist countries. This result implies that the macro-level policy of social redistribution is also important for the development of social welfare in addition to micro-level policy of income redistribution. As we expected, the results show that the level of Korean social welfare development is very low. Considering our levels of economic development and social condition, predicted social welfare expenditure from regression model is at least 17% of GDP, but we are spending only 30% of this predicted expenditure. Another serious problem in Korean social welfare is unbalanced expenditure between social insurance and public assistance. On the basis of these results, this paper suggests three implications for social policy to improve Korean social welfare: First of all, the gap between predicted and actual expenditures should be closed to improve the minimum level of social welfare. Secondly, the level of social condition itself should be improved to increase the public awareness of social welfare. Finally, the wide difference in expenditure between universal and selective social welfare programs should also be removed to decrease the relative deprivation of the poor.

The purpose of this paper is to study whether there are differences in the relationship between IT utilization level and organizational performance among large, medium and small-sized enterprises. This study first assessed the immediate influence of IT utilization level on organizational performance, and then further examined the moderating effects of the organizational size and the environmental dynamism that had influences on the relationship between IT utilization level and organizational performance. The empirical test revealed that IT utilization level had significant impact on organizational performance in case of all sized enterprises. But, the sub-group analysis revealed that IT utilization level had no statistically significant impact on organizational performance in case of large enterprises despite of higher IT utilization level than small and medium-sized enterprises. The relationship between IT utilization level and organizational performance was not moderated significantly by environmental dynamism in case of all sized enterprises. But, the sub-group analysis revealed that environmental dynamism had significant moderating effect on the relationship between IT utilization level and organizational performance in case of large and small-sized enterprises when there was a high level of environmental dynamism.

This study examined the possibility of clustering using 5-year-old children's basic learning ability and mothers' achievement expectation anxiety, and compared the impact of the children's self-regulation ability and mothers' learning involvement for each cluster. The subjects were 239 children (120 boys & 119 girls) aged 5 and attending 9 kindergartens in Seoul, Gyeonggi and Incheon, and also their mothers. The collected data were analyzed using non-hierarchical (K-means) cluster analysis and multivariate logistic regression analysis. The findings of this study were as follows. First, the mother-child pairs were classified into four clusters of 'high learning ability-high expectation anxiety', 'high learning ability-low expectation anxiety', 'low learning ability-low expectation anxiety', or 'low learning ability-high expectation anxiety'group. Second, the level of child's self-monitoring, self-control, and mother's respect and love were significantly higher in the 'high learning ability-low expectations anxiety' group than the 'low learning ability-high expectation anxiety' group. Also, pressure for academic achievement was higher in the 'high learning ability-high expectation anxiety' group than the 'low learning ability-low expectations anxiety' group. Third, child's self-monitoring, mother's pressure for academic achievement, home learning activities, and respect/love for child predicted the clustering using children's basic learning ability and mothers' achievement expectation anxiety.

This study aims to explore the level-specific characteristics of arithmetical thinking based on the arithmetical thinking factors and develop an arithmetical thinking level test that can identify students' arithmetical thinking levels by specifying the levels of arithmetical thinking based on the factors. In order to solve the research problems, we categorized the arithmetical thinking factors into 1~4 levels based on the literature review and constructed items of the arithmetical thinking level test considering both content and process based on the arithmetical thinking factors and the level-specific characteristics of the arithmetical thinking which conformed to the Guttman scale. To investigate the adequacy of the analysis of the arithmetical thinking levels, we reanalyzed the level-specific characteristics of the arithmetical thinking by checking that it matched the factors classified to the test developed by the Guttman scale. From the results of this research, the following conclusions were drawn. First, the arithmetical thinking factors are categorized into four levels which have different characteristics. Second, the arithmetical thinking level test of this study was developed satisfying the Guttman scale and it reflects the level-specific characteristics of the arithmetical thinking levels from 1 to 4. It is possible to determine the students' arithmetical thinking level using this test. Third, according to the results of the final application of the arithmetical thinking level test for 5th and 6th graders, teachers should provide more abundant learning experiences related to the relation level (the level 3) and the application level (the level 4) to increase students' arithmetical thinking level.

The study aims to identify the degree and types of spatial recessions in Si/Gun and Eup/Myun units within Chungcheong region in South Korea to contribute to the efforts being made to diagnose the rural recession and the potentials. To this end, we analyzed 27 Sis and Guns to identify the degree of recession and potentials of rural areas in Chungcheong region. We also carried out the diagnosis and K-Means Clustering on 274 Eups and Myuns, smaller administrative units, to figure out the types and characteristics of the rural recessions. In case of the analysis targeting the Sis and Guns, a relatively high degree of rural recession was found in Cheongyang, Seocheon and Taean for Chungcheongnam-do, and in Danyang and Goisan, as well as in Boeun, Okcheon and Youngdong - which are collectively called as 'Southern 3 Areas in Chungcheongbuk-do' as they are conventionally known by their high degree of rural recession. According to the results of the clustering analysis carried out on the 166 Eups and Myuns, there were five outstanding clusters. They were; areas with housing deterioration (29), areas with poor economic foundation (16), areas with poor accessibility to central areas (42), areas with poor residential environment (51) and areas with aged population (28). The findings and results of the present study are likely to serve as a basis for the design and enforcement of forthcoming rural area activation policies. Also, it would be highly recommended that a more comprehensive diagnosis is taken from a community-level perspective and policy suggestions and strategies tailored for rural communities are further discussed.
