  • Starting from a t-norm T, it is possible to construct a class of new t-norms, so-called T-generalized t-norm. The purpose of this paper is to describe some properties of this class of generalized t-norms. An algebraic structure as well as a binary relation among t-norms are also investigated. Some open problems are discussed as well.

  • 본 연구는 사회적자본이 사회적경제 인식에 영향을 미치는 요인을 검증하고 살펴보고자 하였다. 연구의 결과를 요약하자면 다음과 같다. 사회적자본이 사회적경제 인식에 미치는 영향을 분석한 결과 규범(t=3.228, p<.01), 참여(t=3.057, p<.01)가 사회적경제 인식에 유의미한 영향을 미쳤다. 즉, 규범을 잘 준수할수록, 참여가 높을수록 사회적경제 인식에 영향을 주는 것으로 나타났다. 이러한 결과를 바탕으로 다음과 같은 시사점을 도출하였다. 첫째, '규범'이란 사회 내에서 공동체 구성원들이 지켜야 할 규칙이나 기준을 의미하는데 이러한 규범은 개인들의 행동을 조절하고, 사회적 협력을 촉진하는 역할을 한다. 이를 통해 강력한 규범 체계가 있으면 사회적경제 활동에 참여하거나 협력하는 방식에 큰 영향을 줄 수 있을 것으로 여겨진다. 둘째, '참여'는 개인이나 집단이 사회적 활동에 얼마나 적극적으로 참가하는지를 나타내는 지표이다. 사회적자본을 통해 참여도가 높은 사람들은 사회적경제 인식에 대해 높은 이해력을 가지며, 효과적으로 행동할 수 있을 것이다. 이러한 결과는 선행연구에서는 규범을 잘 준수할수록, 신뢰와 네트워크가 강화로 될수록 사회적경제 인식이 높아졌다. 이와는 달리 본연구에서는 규범과 신뢰는 영향을 주는 것으로 나타났지만 네트워크는 영향을 주지 않는 결과로 선행연구 결과와는 차이가 있는 것으로 나타나 추후 반복적인 연구가 필요할 것으로 생각된다. 이상의 결과를 살펴볼 때 규범과 참여라는 사회적자본의 요소를 강화하고 발전시키면 전반적인 사회경제 인식 및 발전에 긍정적인 영향으로 미칠 수 있을 것이다.

  • Purpose: Influenza immunization among health personnel is of particular importance given their elevated risk of influenza infection, role in transmission and influence on patients' immunization status. The purpose of this study is to identify factors associated with the influenza vaccination intention among health personnel based on the theory of planned behavior. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 131 health personnel in five general hospitals in two cities in South Korea. The data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with the SPSS 26.0 program. Results: There were statistically significant differences in influenza vaccination intention according to the high-risk group in the family, occupation, length of employment, and influenza vaccination status within a year. The influenza vaccination intention of these health personnel showed significant positive correlations with attitude, subjective norms, and perceived behavioral control towards influenza vaccination. Multiple regression analysis for influenza vaccination intention revealed that the significant predictors were attitude, subjective norms, influenza vaccination within a year and physician in occupation. These factors explained 41.4% of the variance. Conclusion: The results suggest a need to strengthen attitude and subjective norms. The findings also suggest that their characteristics through influenza vaccination status within a year and occupation should be considered for tailored interventions related to the intention. Furthermore, it is necessary to develop programs strengthening attitude and subjective norms to enhance influenza vaccination intention among health personnel.

  • The purpose of this study was to investigate the weight control attempts and related factors among 220 female college students in Seoul. Factors examined included body image, body satisfaction, interest in weight control, beliefs related to weight control, social norms, social expectations regarding subjects' body size and weight change. Data were analyzed using t-test and chi-square test(at $\alpha$=0.05). The average height and weight of subjects were 160.7cm, 52.2kg respectively. BMI and body fat(%) were 20.2 and 25.2%, respectively. One hundred seventy two students(78.2%) had attempted to control their weight, mainly to lose weight, and were categorized as the weight control attempt group. Subjects used diet modification as well as unhealthy method to control weight. 48.2% in the attempt group were underweight or normal weight(by BMI), suggesting that their weight control attempts were was unnecessary. Students in the attempt group described their own size as heavier than those in the no-attempt group(p<0.01) or other girls of their age(p<0.05) ; more dissatisfied with their body size(p<0.01), and showed more interest in weight control(p<0.01). Several differences in beliefs were also noted(p<0.001). The attempt group believed less strongly in the harmful effects or difficulties in weight control and believed more strongly in the advantages of weight control. With respect to social factors, the attempt group perceived that their family and friends wanted them to be smaller than they were(p<0.001), perceived that significant others felt that they should lose weight(p<0.05). These results suggest that educational programs for college female students should start focusing on the harmful effects of excessive dieting and information about desirable weight control methods. Students should be helped to have a correct body image. In addition, educational programs should incorporate strategies to change beliefs regarding weight control, as well as modifying social expectations from significant others.

  • Purpose: The purpose of this study was to examine the awareness of alcohol use during pregnancy and factors influencing the intention to abstain from alcohol during pregnancy by drinking levels. Methods: Utilizing a comparative descriptive design, a total of 359 female college students were recruited. Measurements were Theory of Planned Behavior (TPB) variables related awareness of alcohol use during pregnancy, Korean Version of the Alcohol Use Disorders Identification Test, knowledge about alcohol use during pregnancy, and socio-demographic factors. Main variables were compared by drinking levels. The factors influencing the intention to abstain from alcohol during pregnancy were identified using hierarchical regression analysis. Results: Non-problematic alcohol behavior group (n=185) had higher the intention to abstain from alcohol during pregnancy than problematic alcohol behavior group (n=174) (t=3.13, p=.002). The significant TPB variables influencing the intention to abstain from alcohol during pregnancy were that attitudes (β =-.44, p<.001), subjective norms (β =.14, p=.026), and perceived behavior control (β =.19, p=.002) in non-problematic alcohol behavior group, whereas the corresponding variables in the problematic alcohol behavior group were attitudes (β =-.51, p<.001) and subjective norms (β =.21, p=.006). Conclusion: It is necessary to increase the intention to abstain from alcohol during pregnancy for the female college students having problematic alcohol behavior. The following strategies are recommended for them; decreasing acceptable attitudes toward alcohol use during pregnancy and reinforcing the influence of social pressure toward to abstain from alcohol during pregnancy.

  • This paper presents cross-national perspectives on challenges in implementing current mathematics education reform ideals. This paper includes detailed qualitative descriptions of mathematics instruction from unevenly successful second-grade classrooms both in Koran and in the U. S with regared to reform recommendations. Despits dramatic differences in mathematics achivement between Korean and the U.S student. problems in both countries with regard to mathematics education are perceived to be very similar. The shared problems have a common origin in teacher-centered instruction. Educational leaders in both countries have persistently attempted to change the teacher-centered pedagogy to a student-centered approach. Many teachers report familiarity with and adherence to reform ideas, but their actual classroom teaching practices do not reflect the full implications of the reform ideals. Given the challenges in implementing reform, this study explored the breakdown that may occur between teachers adoption of reform objectives and their successful incorporation of reform ideals by comparing and contrasting two reform-oriented classrooms in both countries. This comparison and contrast provided a unique opportunity to reflect on possible subtle but crucial issues with regard to reform implementation. Thus, this study departed from past international comparisons in which the common objective has been to compare general social norma of typical mathematics classes across countries. This study was and exploratory, qualitative, comparative case study using grounded theory methodology based on constant comparative analysis for which the primary data sources were classroom video recordings and transcripts. The Korean portion of this study was conducted by the team of four researchers, including the author. The U.S portion of this study and a brief joint analysis were conducted by the author. This study compared and contrasted the classroom general social norms and sociomathematical norms of two Korean and two U.S second-grade teachers who aspired to implement reform. The two classrooms in each country were chosen because of their unequal success in activating the reform recommendation. Four mathematics lessons were videotaped from Korean classes, whereas fourteen lessons were videotaped from the U.S. classes. Intensive interviews were conducted with each teacher. The two classes within each country established similar participation patterns but very different sociomathematical norms. In both classes open-ended questioning, collaborative group work, and students own problem solving constituted the primary modes of classroom participation. However in one class mathematical significance was constituted as using standard algorithm with accuracy, whereas the other established a focus on providing reasonable and convincing arguments. Given these different mathematical foci, the students in the latter class had more opportunities to develop conceptual understanding than their counterparts. The similarities and differences to between the two teaching practices within each country clearly show that students learning opportunities do not arise social norms of a classroom community. Instead, they are closely related to its sociomathematical norms. Thus this study suggests that reform efforts highlight the importance of sociomathematical norms that established in the classroom microculture. This study also provides a more caution for the Korean reform movement than for its U.S. counterpart.
