In this paper, muscular activity and muscle fatigue of FDI(first dorsal interosseous muscle) and thenar muscle of hand was analyzed with surface EMG signal based on four kinds of attitudes(grip, tip, key and palmar) to measure grip strength and pinch strength after hand operation and rehabilitation treatment. The normative data are needed to interpret evaluation data to assess a patient's ability to return to labor environment. The preceding researchers proposed the standard data only by studying on maximum grip strength and the maximum pinch strength followed by each attitude of subjects' hands. But in this study, the muscle activity and muscle fatigue were considered under the various attitude to propose normative data. As a results, the muscle fatigue may be used only for presentation of normative data in labor environment.

Objectives: The purpose of this study was to evaluate depression of mothers with children in early childhood and to identify predictors by income level. Methods: The research was conducted with 1,761 data from the 3rd wave of the Panel Study of Korean Children(PSKC) data. Independent variables were socio-demographic data, self-esteem, normative life-events, non-normative life events, parenting stress, marital conflict, social support. Data were analyzed by t-test, ANOVA, hierarchical multiple regression analysis were conducted. Results: Significant factors of depression of female in low-income were non-normative life events, parenting stress, marital conflict. In middle class, significant factors were education, birth order of children, self-esteem, normative and non-normative life events, parenting stress, marital conflict, sociable support. At last, we found that marital conflict was the biggest factor for depression of female in low-income and parenting stress was the most powerful predictor in middle class. Conclusions: Mother's depression has a enormous impacts on development of children in early childhood. Therefore It is required to prevent depression in mothers and it is important to intervene at the early stage of depression. Results of this study showed a different pattern of predictors by income level. Therefore, Intervention and services for a mother's depression should change the direction depending on the level of income.

In the modern digitized data society, there is a growing emphasis on securing trustworthiness and fairness in data utilization, along with data openness. By defining the concept of data democracy from various perspectives and presenting elements of normative values, this study aims to provide a basic conceptual framework to identify and evaluate the data governance system and levels of data democracy. As a foundation for the discussion of data democracy, based on Kneuer's (2016) conceptualization of e-democracy, free and equitable access, e-participation, and e-government were introduced as core dimensions of e-democracy. To improve the quality of data governance and foster a better understanding and practical application of the concept of data democracy, this study takes a normative approach from the perspective of democracy. Inclusiveness, equity, participation, and democratic sovereignty are provided as core dimensions of data democracy. This study highlights the significance of data literacy in promoting data democracy. It proposes the creation and assessment of a curriculum rooted in the normative principles of data democracy within the field of library and information science for future investigation.

Objective: Understanding the orofacial characteristics and growth patterns in children is essential for both orthodontics and research on children with orofacial abnormalities. However, a concise resource of normative data on the size and relative position of these structures in different populations is not available. Our objective was to aggregate normative data to assess the growth of the orofacial skeletal structures in children with a well-balanced face and normal occlusion. Methods: The MEDLINE, Embase, and Scopus databases were searched. Inclusion criteria included longitudinal and cross-sectional studies on cephalometric measurement of skeletal tissues and a study population ≤ 18 years with a well-balanced face and normal occlusion. Key study parameters were extracted, and knowledge was synthesized. A quality appraisal was performed using a 10-point scale. Results: The final selection comprised of 12 longitudinal and 33 cross-sectional studies, the quality of which ranged from good to excellent. Our results showed that from childhood to adulthood, the length of the cranial base increased significantly while the cranial base angle remained constant; both the maxilla and mandible moved forward and downward. The profile becomes straighter with age. Conclusions: Growth patterns in children with a well-balanced face and normal occlusion follow accepted theories of growth.

Purpose: The purpose of this study was to propose useful standards evaluation method using standards networks by analyzing the relationship between normative references citation information list. Methods: The collected data through the survey were analyzed using social network analysis. The measurement tools used for this study were divided into three dimensions such as certificate standard, normative reference and degree centrality. Results: The results of this study are as follows; regarding the influence of standard information, It is meaningful that the research using normative reference item among the bibliography information that the standard itself possesses. The analysis of social network analysis data of population standard, normative reference and the correlation analysis with sales, a variable representing actual utilization performance, suggested the importance of the standard and how to evaluate it. Conclusion: In prioritizing standard maintenance, more efficient management will be possible if centrality figures of standard network information are analyzed and used for standard maintenance.

The purpose of the present study was to investigate relation.;hip between normative influence on clothing conformity and authoritarian personality, fashion interest, and clothing importance. The sample of this study consisted of 756 subjects assigned to eight groups according to sex, age and residence. In this study normative influence on clothing conformity, fashion interest, and clothing importance were measured by 20 Likert type questions adopted from previous research or developed for this study. Authoritarian personality was measured by Min's 35 Likert type questions. The data were analyzed by ANOVA, multiple regression and correlation. The results showed that 1) authoritarian personality, fashion interest, and clothing importance was positively related to normative influence on clothing conformity. Among these, fashion interest was the most significant varible. 2) Normative influence on clothing conformity varied by sex and age: that is, females conformed more than males, and younger sample conformed more than older sample.

The purpose of the study is to investigate the types of apparel usage situations percieved by female consumers. Data (N=132) were collected via a questionnaire developed on the focused stoup interviews and previous studies. By multidimensional scaling (MDS) analysis, two dimensions of perceptual criteria on apparel usage situations are identified: formality, and normative aspects of apparel style. Results indicate that apparel usage situations perceived by female consumers can be classified into four major types: (1) Formal-Normative Situations, (2) Informal-Normative Situations, (3) Informal-Normless Situations, and (4) Formal-Normless Situations.

The purpose of this study was to examine that marital conflict, maternal parenting behavior, and a child's friendship quality varied as a function of bully/victim groups. A sample of 227 elementary school children and their mothers participated in the study. Children answered questionnaires regarding maternal parenting behavior, friendship quality, and bullying/victimization and mothers rated their marital conflict. The data were analyzed by frequencies, factor analysis, one-way ANOVAs, and Duncan's post-hoc analyses. The bully/victim distribution was 8.4% bullies, 7.9% victims, 4.4% bully-victims, and 79.3% normative contrasts when reported by children themselves and 9.3% bullies, 4.8% victims, 5.3% bully-victims, and 80.6% normative contrasts when reported by peers. Bullies and bully-victims experienced higher marital conflict than normative contrasts. Bully-victims perceived higher maternal warmth than bullies and both bullies and victims perceived higher maternal rejection/punishment than normative contrasts. Victims perceived their mothers to be more permissive/neglected than normative contrasts, and bully-victims perceived them to be more overprotective than both bullies and normative contrasts. Both bullies and bully-victims showed higher negative function of friendship quality than victims.

Objectives : The K-ARS (Korean ADHD Rating Scale) is one of the most important assessment tool of attention-deficit hyperactivity disorder (ADHD) in Korea. in this study, we presented detailed normative data on the K-ARS for school-aged children in Seoul metropolitan area to put it to practical use. Methods : The subjects were 2,397 students(1,223 boys and 1,174 girls, aged 6-12) from 4 elementary schools in Seoul, and one caretaker of each child completed the K-ARS for parents. Children who showed high scores of the K-ARS for parents were screened, and 2 child psychiatrists interviewed them to make a clinical diagnosis. We compared the mean scores of the K-ARS for parents between ADHD and normal group, and examined the percentage of correct classification. Results : There were some differences in score of the K-ARS for parents according to sex and age, so we presented continuous normative data with T score and subdivided cut-off points for ADHD screening. Interviews with child psychiatrists using DSM-IV criteria were performed to test diagnostic validity, and the difference in every the K-ARS for parents index between ADHD and normal group was significant(p<.001). Using 3 different cut-of points(80th, 90th, 93rd percentage), the accuracies of ADHD correct classification were 67.9, 72.2, 71.1% and all 3 canonical discriminants were significant (p<.05) between ADHD and normal group. Conclusion : The normative data and cut-off points on the K-ARS for parents are useful in screening ADHD children in Seoul metropolitan area.

The purpose of this paper is to examine bedroom-need norms and the relationship between normative deficits for bedroom sharing and housing space satisfaction of adolescent. Three cases were mainly considered to apply for adolescents to share a bedroom: maximum age and number limits of a child sharing a parents'bedroom, maximum age of an old child sharing a bedroom with its siblings of the opposite sex, and maximum age of an old child sharing a bedroom with its siblings of the same sex. The data were collected 400 eighth grade students in the three different size of regions, June-July, 1999 and 379 cases were finally analyzed. The result showed that the normative deficits for bedroom sharing was a statistically signiticant factor to explain housing space satisfaction of adolescents even though the condition of bedroom sharing was the most influencial variable. This reset supports the family housing adjustment behavior model of Morris and Winter.
