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.

This study sought to verify and examine the factors that influence social capital on social economy awareness. To summarize the results of the study, the results are as follows. As a result of analyzing the impact of social capital on social economy awareness, norms (t=3.228, p<.01) and participation (t=3.057, p<.01) had a significant impact on social economy awareness. In other words, the better the norms are observed and the higher the participation, the more influence it has on social economy awareness. Based on these results, the following implications were drawn. First, 'norms' refer to rules or standards that community members must adhere to within society, and these norms play a role in regulating the behavior of individuals and promoting social cooperation. Through this, it is believed that a strong normative system can have a significant impact on the way people participate or cooperate in social economy activities. Second, 'participation' is an indicator of how actively an individual or group participates in social activities. People with high levels of participation through social capital will have a high level of understanding of social economy awareness and will be able to act effectively. These results show that in previous studies, the better the norms were observed and the more trust and networks were strengthened, the higher the awareness of social economy. In contrast, in this study, norms and trust were found to have an effect, but the network did not, showing a difference from the results of previous studies, so repeated research is expected to be necessary in the future. Considering the results above, strengthening and developing the elements of social capital such as norms and participation can have a positive impact on overall socioeconomic awareness and development.

The purpose of present study was to develop the Korean Version of Luria-Nebraska Neuropsychological Battery for Children(LNNB-C), to examine the reliability of it, and to establish the norms for determining the probability of brain damage. The normative group used to standardize the Korean version of LNNB-C was composed of 147 children between the age of 8 and 12(body 74, girl 73). The clinical group consisted of 19 brain damaged, 16 ADHD, and 16 psychiatric controls. The inter-scorer reliability was 96.3%, indicating that the stability of the scoring system for the Korean version of LNNB-C is good. The reliability coefficients(Cronbach's ${\alpha}$) of LNNB-C scales were ranged .51 to .91, which are similar to those of original LNNB-C. To establish the norms for detecting brain damage, the means and standard deviations for normative group were used to calculate T-scores for each scale. To determine a critical level that could successfully predict a normal child's average score at a given age, first the average score of normative group was calculated, and this score was then entered a regression equation with age to predict the average(baseline) acore. Finally, some issues on constructing the Korean version of LNNB-C and the cultural differences between Korean and American children in performing LNNB-C were discussed.

Purpose: The purpose of this study was to investigate the predictors of tuberculosis (TB) drugs in health care workers diagnosed with latent tuberculosis Infection (LTBI). Methods: This study was a descriptive correlation study. Data were collected by using a self-report questionnaire. The collected data were analyzed by -test, t-test, and logistic regression analysis. Results: There were involved 160 participants, 35 (21.9%) who took the TB drugs, and 125 (73.8%) who did not take the TB drugs. The predictors on taking TB drugs in health care workers with LTBI were subjective norms (OR=3.33, p<.001), perceived sensitivity (OR=2.67, p=.026), perceived barrier (OR=0.14, p=.014), and unmarried (OR=4.69, p=.006) than married, health care worker category 2 group (OR=5.84, p=.015) and 1 group (OR=4.25, p=.022) than 3, 4 group, sleep over 7 hours (OR=4.11, p=.022) than less 7 hours sleep. Conclusion: In order to promote the use of TB drugs in health care workers with LTBI, it is necessary that take intervention strategies to increase the subjective norms and perceived sensitivity and to decrease the perceived barriers.

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.

The purpose of this study was that HPV prevention education based on the planned behavioral theory was designed to provide college students with HPV vaccine knowledge, cervical cancer knowledge, attitude toward HPV vaccination, subjective norms for HPV vaccination, perceived behavioral control for HPV vaccination, and HPV vaccination. This is an experimental study to confirm the effect on the intention to vaccinate and the behavior of HPV vaccination. The subjects were arbitrarily expressed as 32 subjects in the experimental group and 34 subjects in the control group. The collected data were analyzed by descriptive statistics, t-test, χ²-test, Fisher's exact test and repeated Measures ANOVA. As a result, the experimental group participating in HPV prevention education was compared to the control group who did not participate in HPV vaccine knowledge (t=5.66, p<.001), cervical cancer knowledge (t=4.13, p<.001), attitude (t=2.24, p=) .032 ), subjective norm (t=2.83, p=.008), perceived behavioral control (t=2.65, p=.013), and intention (t=3.91, p<.001) were significantly different. After 4 weeks of HPV prevention education intervention, there was a significant difference in the interaction between group and time course of HPV vaccination intention (F=6.95, p=.002). Therefore, it was confirmed that HPV prevention education is an educational program that can be applied to college students.
