Geomorphological development and distribution at the macro scale provide a clue to the geotectonic characteristics that have affected the geomorphological system. This is because the developmental characteristics and distribution of the landform at the macro scale remain spatial characteristics due to tectonic processes, such as fault activity. From the perspective of tectonic geomorphology, this study identified the developmental characteristics and distribution of the Quaternary landforms in central-southern Yangsan fault and discussed its relevance to fault activity. In this paper, we presented examples and results of morphotectonic analysis of the Yangsan fault, and will present the results of age dating, stratigraphic relationship of the Quaternary landforms, and calculation of cumulative slip rate in the next paper.

Purpose: From the holistic environmental perspective, individual and environmental influences on low-income children's questionable development were identified and examined as to differences in the influences according to the child's developmental stage of infancy (age 0-35 months) or early childhood (age 36-71 months). Methods: This study was a cross-sectional comparative design using negative binominal regression analysis to identify predictors of questionable development separately for each developmental stage. The sample was comprised of 952 children (357 in infancy and 495 in early childhood) from low-income families in South Korea. Predictors included individual factors: child's age and gender; proximal environmental influences: family factors (family health conditions, primary caregiver, child-caregiver relationship, depression in primary caregiver) and institution factors (daycare enrollment, days per week in daycare); and distal environmental influences: income/resources factors (family income, personal resources and social resources); and community factors (perceived child-rearing environment). The outcome variable was questionable development. Results: Significant contributors to questionable development in the infancy group were age, family health conditions, and personal resources; in the early childhood group, significant contributors were gender, family health conditions, grandparent as a primary caregiver, child-caregiver relationships, daycare enrollment, and personal resources. Conclusion: Factors influencing children's questionable development may vary by developmental stage. It is important to consider differences in individual and environmental influences when developing targeted interventions to ensure that children attain their optimal developmental goals at each developmental stage. Understanding this may lead nursing professionals to design more effective preventive interventions for low-income children.

The present study explored a relationship between mathematical understandings of teachers and ways in which their knowledge transferred in designing lessons for hypothetical students from Gess-Newsome (1999)'s transformative perspective of pedagogical content knowledge. To this end, we conducted clinical interviews with four secondary mathematics teachers of their solving and teaching of equation writing. After analyzing the teacher participants' attention to Key Developmental Understandings (Simon, 2007) in solving equation writing, we sought to understand the relationship between their mathematical knowledge of the problems and mathematical knowledge in teaching the problems to hypothetical students. Two of the four teachers who attended the key developmental understandings solved the problems more successfully than those who did not. The other two teachers had trouble representing and explaining the problems, which involved reasoning with improper fractions or reciprocal relationships between quantities. The key developmental understandings of all four teachers were reflected in their pedagogical actions for teaching the equation writing problems. The findings contribute to teacher education by providing empirical data on the relationship between teachers' mathematical knowledge and their knowledge for teaching particular mathematics.

Social epidemiology is a sub-discipline of epidemiology explicitly investigating social determinants of population distributions of health, disease, and well-being. Persistent pattern of social inequalities in health in spite of the broad improvement in the physical environment over the last centuries necessitated the development of this field as an approach to understand disease etiology that incorporates social experiences as more direct determinant of health. Social epidemiology incorporates theories, measurement tools, and techniques from a wide variety of other social sciences. A population perspective, the social context of behavior, contextual multilevel analysis, a developmental and life-course perspective, and general susceptibility to disease are the most important guiding concepts in social epidemiology.

The concept of pedagogical content knowledge (PCK) has been developed and expanded to identify essential components of mathematical knowledge for teaching (MKT) by Ball and her colleagues (2008). This study proposes an alternative perspective to view MKT focusing on key developmental understandings (KDUs) that carry through an instructional sequence, that are foundational for learning other ideas. In this study we provide constructive components of KDUs in fraction multiplication by focusing on the constructs of 'three-level-of-units structure' and 'recursive partitioning operation'. Expecially, our participating preservice elementary teacher, Jane, demonstrated that recursive partitioning operations with her length model played a significant role as a KDU in fraction multiplication.

It is needed to connect the curriculum of leisure use with community resources in order to allow students with developmental disability in a transition period to recover composure themselves through the curriculum of leisure use, improve their skills to enjoy, and apply their independent ability to utilize the actual leisure resources in a community through community programs. To realize this, it is necessary to secure recognition of leisure use from teachers instructing leisure use as a curriculum and examine points to be improved and importance mentioned about community-based leisure activity participation. The latest research on lifelong planning extends leisure activity from existing elements and implies the necessity of preparation in holistic aspects. As the crucial resources of leisure activity for students with developmental disability, this author focuses on the importance of leisure activities in schools and in communities and provides supportive measures to elevate accessibility to leisure activity.

Bring this analysis down to people-centered development perspective and looking through democratization in the Philippines, Thailand and Indonesia, we find similarities and differences among them related with the intensity of conflicts between development and human rights in the process of democratization in line with global transformation. Civil society in the Philippines criticized the developmental path in the Philippines which failed to implement land reform and eradication of poverty under the transition from 'patrimonial oligarchy' to democracy. In Thailand the coalition of military and the royalists had consolidated its power since Sarit military regime, which later paved the way 'hybrid oligarchy' era. Most Thai civil society organizations has regarded their developmental experience rather as 'maldevelopment' which disregarded economic and social rights. It has been especially believed by Thai localists that the stimulation of local markets and the building of autonomic community society will form the alternative economy without going against the conservative banner of nation, religion and king. Thaksin as a populist successfully took advantage of Thai localist ethos in favour of taking the seat of power. He projected himself as a modernizer focused on economic growth and cleaner politics. However Thaksin's procedural legitimacy was overthrown by counterattacking from military-royalist alliance, pretexting that Thaksin caused internal conflicts and lacked morality. Soeharto's New Order regime which can be called 'administrative oligarchy' had an antipathy towards notions of economic and social rights as well as civil and political rights. In spite of the fact that the fall of Soeharto opened the political space for democratic civil society organizations which had long struggled with development aggression and human rights abuses, there have been continuously a strong political and military reaction against human rights activists, NGOs and ethnic minorities such as Aceh and Papua. Nevertheless, Indonesian democracy is more promising than Philippine's and Thai democracy in terms of comparatively less pre-modern legacies.

Based on the premise that perspectives or the frame of cognition may affect the ways that family practitioners support or intervene in families, this study aimed to investigate the perspectives of Certified Healthy Family Specialists (CHFS) on family practice in the Healthy Family Support Centers. A total of 9 CHFSs gave information about their beliefs and perspectives on family practice in in-depth interview. Additionally, 5 CHFS participated in focus group interview and gave information about their values, beliefs, and perspectives on family practice. Through qualitative analyses, four perspectives were found to be explicitly or implicitly carried by CHFSs: System theory perspective, Strengths perspective, Family cognition perspective, and Public intervention perspective. These four perspectives are currently leading themes of family research and are prospected to prevail in family support and intervention practices in the Healthy Family Support Centers in South Korea. Based on the results of qualitative analyses, directions and range of influence in perspectives on family practice perceived by CFHSs were discussed. In this study, the subject of Healthy Family Project, the CHFSs' aims, and emphasis on family practice were dealt with, and developmental direction establishment related to the Healthy Family Support Centers and CFHSs in the dimension of practice and policy in the future were implied.

Remarriage has been prevalent in Korea since the mid-1990s. Remarried families have reported that they face many challenges and difficulties. Life for those who remarry can worsen when the children from a previous marriage live together with new family members. It is interesting that some remarried families adjust well while others do not. This study focuses on developing a practice model for strengthening the resilience of remarried families with children based on a literature review. To understand and support remarried families, the resilience perspective was chosen, focusing on a strengths perspective with developmental, ecological, and preventative perspectives. In terms of resilience, the proposed practice model was developed on the basis of three concepts: belief systems, organizational patterns, and communication. The model can be used to help remarried families accomplish adequate integration by growing as a new family and can prevent another divorce. Moreover, it can assist practitioners and policy-makers develop programs and policies with a strengths perspective rather than a deficit or problem-oriented perspective. Based on the model, various programs need to be developed to strengthen the resilience of remarried families. The development of supportive programs is suggested. These can include remarriage preparation programs, remarriage life education programs, interactive web-based programs, and family camps. For a long time, remarried families have been labeled as abnormal and atypical owing to the normal family myth. This negative perception of remarried families must be altered so that they are accepted with a positive outlook in a society. For further studies, the development of diverse supportive adaptation programs for various types of remarried families and active research on them are recommended. The practice model can assist with the adaptation and growth of remarried families by strengthening their resilience.
