  • 유수의 침식과 퇴적작용은 지형의 변화를 일으키며, 이런 지형변화는 하천 흐름, 지하수 흐름 등의 변화를 가져오며 이는 다시 지형변화의 원인이 된다. 이런 일련의 과정이 되풀이되는 것을 지형발달이라 하며, 이는 수문 현상에도 지대한 영향을 미친다. 지형발달의 주요 인자에는 강우와 지반 융기 등이 있으며 각 주요 인자들은 복합적으로 지형발달에 영향을 준다. 하지만 지형발달 탐구 시 실제 지형을 대상으로 탐구하기에는 한계가 분명히 있다. 그래서 본 연구에서는 컴퓨터를 이용해 수식을 계산하여 수치적으로 지형발달을 모의하는 모형을 이용하여, 지형발달에 영향을 주는 강우와 지반 융기를 중점적으로 탐구하였다. 지형발달모형을 이용하면 더욱 다양한 관점에서 지형발달과정의 역동성을 파악하는 새로운 시도들이 가능하다. 특히 특정 환경 조건에서의 논리적인 지형의 반응을 통한 해석이 가능해져, 환경 변화로 어떠한 지형변화 또는 지표물질 수지 변화가 있을지를 예측할 수 있다(변종민, 2011). 또한, 지형발달 일련의 과정들을 살펴볼 수 있기 때문에 시 공간적 제약에서 벗어날 수 있다. 그러므로 지형발달모형은 강우와 융기 조건에 따른 지형발달을 모의하기에 적합하다. 본 연구는 LEGS을 이용하여 강우와 융기 조건에 따른 지형발달 모의를 진행하였다. LEGS는 지표수의 흐름을 탐색하는 방법으로 GD8을 이용한 물리 기반의 수치적 지형발달모형이다(Paik, 2012). 본 연구에서는 강우의 변동과 융기 조건의 변화가 지형발달에 상당한 영향을 미치는 것을 발견하였다. 특히, 유역의 표고차이 등과 같은 정량적인 지표의 변화에 주목하여 각종 분석을 하고, 물리적 원인을 고찰하였다.

  • This paper explores the historical process that created a specific understanding of and responses to atopic dermatitis(AD) in Korea. AD hardly has a status of an environmental disease in other societies but it is a representative environmental disease in South Korea in connection with various environmental pollutants, most notably with endocrine disrupting chemicals. This understanding of AD as an environmental disease led to an unprecedented legislation of the Environmental Health Act of 2008, a broad environmental health law with the precautionary principle and the focus on human aspect of environmental problems. In line with the growing body of works that articulate the roles of the public and culture in regulatory process, this paper argues that both the understanding of and the regulatory responses to AD owe greatly to the knowledge and political practice of the public, especially that of the 'Atopy moms'. Their knowledge practice that creatively appropriated scientific uncertainty regarding AD brought unexpected epistemological and political alliances, respectively with alternative medicine and with organic coop movement and an emergent political party and generated enough dynamics for the legislation of the EHA.

  • This thesis compares and analyzes the dynamics between policy, knowledge and power of Myanmar's higher education development. The papers begins by exploring the dynamics during the Socialist Military Regime(1962~1988), the Collapse of Higher Education Era(1988~2010), Thein Sein's Reform Era(2010~2015) and the current Aung San Suu Kyi's Civilian Era(2015~Now). By highlighting recent dramatic policy changes, the article argues that the policy discourse on the subject of internationalization of higher education and the technocratization of education development policy by the current Civilian Government in its new policy discourse, that resulted in the active participation as well as the contributions of international donors has directly impacted on the policy dynamics around the Comprehensive Education Sector Review and the introduction of the National Education Strategic Plan 2016~2020. Further, by examining complex interaction between the current domestic education stakeholders and international donors in education sector in Myanmar, this thesis argues that the new analytical framework on the understanding of policy dynamics in developing countries goes beyond the national level. The paper argues that there needs to be broadening of the analytical framework towards the multidimensional analysis perspective that includes global, national as well as local level policy, knowledge and power dynamics in Myanmar's dynamically changing higher education sector.

  • Family is a primary unit of the major socialization processing for children. Parents among the family members are one of the most important figures from whom the child and adolescent acquire a wide variety of behavior patterns, attitudes, values and norms. An organization of family members product family structural functioning. Abnormal family structure is one of the most important reference models in the learning of antisocial patterns of behavior. Therefore incest and child sexual abuse including spouse abuse, elderly abuse, and neglect occurs in the abnormal family structural setting. In particular, incest, a specific form of sexual abuse, was once thought to be a phenomenon of great rarity, but our clinical experiences, especially over the past decade, have made us aware that incest and child sexual abuse is not rare case and on the increasing trend. Therefore, the aim of this study was to determine the family problem and dynamics of incest family, and character pattern of post-incest adolescent victim in Korea. A total of 1,838 adolescents from middle and high school(1,237) and juvenile correctional institute(601) were studied, sampled from Korean student population and adolescent delinquent population confined in juvenile correctional institutes, using proportional stratified random sampling method. The subjects' ages ranged from 12 to 21 years. Data were collected through questionnaire survey. Data analysis was done by IBM PC of Behavior Science Center at the Korea university, using SAS program. Statistical methods employed were Chi-square, principal component analysis and t-test etc. The results of this study were as follows ; 1) Of 1,071 subjects, 40(3.7%) reported incest experiences(sibling incest : 1.6% ; another type of incest : 2.1%) in their family setting. 2) The character pattern of post-incest adolescent victim was more socially maladjusted, immature, impulsive, rigid, anxious and dependent than non-incest adolescent. Also they showed some problem in academic performance and their assertiveness. 3) The other family members of incest family revealed more psychological and behavioral problem such as depression, alcoholism, psychotic disorder and criminal act than the non-incest family, even though there is no evidence of the context between them. 4) The family dynamics of incest family tended to be dysfunctional trend, as compared with non-incest family. It showed that the psychological instability of family member, parental rejection toward their children, coldness and indifference among family member and marital discordance between the parents had significant correlation with incest.

  • Mobile ad hoc networks (MANETs) are infrastructure-less and stand-alone wireless networks with dynamic topologies. To support user's safety in MANETs, fundamental and various security services should be supported. Especially in mobile commercial market, one of the major concerns regarding security is user privacy. Recently, researches about security system to protect user privacy in cluster-based MANETs have been introduced. This paper propose a cluster reconfiguration protocol under anonymous cluster-based MANETs to enhance the network stability. The improved anonymous cluster-based MANETs can recover the network structure against abnormal states of clutserheads.

  • 본 논문의 목적은 Cabri II 를 이용하여 형식적이고 연역적인 증명수업 방법의 대안을 찾는 데 있다. 형식적인 증명을 하기 전에 탐구와 추측을 통한 발견과 그 결과에 대한 비형식적인 증명 활동을 강조한다. 역동적인 기하소프트웨어인 Cabri II 는 작도가 편리하고 다양한 예를 제공하여 추측과 탐구 그리고 그 결과의 확인을 위한 풍부한 환경을 제공할 수 있으며, 끌기 기능을 이용한 삼각형의 변화과정에서 관찰할 수 있는 불변의 성질이 형식적인 증명에 중요한 역할을 한다. 또한 도형에 기호를 붙이는 활동은 형식적인 증명을 어렵게 만드는 요인 중의 하나인 명제나 정리의 기호적 표현을 보다 자연스럽게 할 수 있게 해 준다. 그러나, 학생들이 증명은 더 이상 필요 없으며, 실험을 통한 확인만으로도 추측의 정당성을 보장받을 수 있다는 그릇된 ·인식을 심어줄 수도 있다. 따라서 모든 경우에 성립하는 지를 실험과 실측으로 확인할 수는 없다는 점을 강조하여 학생들에게 형식적인 증명의 중요성과 필요성을 인식시킬 필요가 있다. 본 연구에 대한 다음과 같은 후속연구가 필요하다. 첫째, Cabri II 를 이용한 증명 수업이 학생들의 증명 수행 능력 또는 증명에 대한 이해에 어떤 영향을 끼치는지 특히, van Hiele의 기하학습 수준이론에 어떻게 작용하는 지를 연구할 필요가 있다. 둘째, 본 연구에서 제시한 Cabri II 를 이용한 증명 교수학습 방법에 대한 구체적인 사례연구가 요구되며, 특히 탐구, 추측을 통한 비형식적인 중명에서 형식적 증명으로의 전이 과정에서 나타날 수 있는 학생들의 반응에 대한 조사연구가 필요하다.

  • Human responses, such as construction of levees, are a spatial representation of the place vulnerability which is induced by a geomorphic hazard like flooding. Human responses include all forms of human activities to reduce the place vulnerability and they seem to be related with reducing vulnerability rather than reducing geomorphic hazards. Diverse human responses to the perceived environment bring about changes in the place vulnerability. People respond spatially to their vulnerability of the place in diverse ways from their experience and perceived risk. Human responses have quantitative possibilities in predicting and modeling the place vulnerability. Building the model of a dynamic place vulnerability to the diverse geomorphic hazards requires basic maps of geomorphic processes and human responses in the region.

  • Organizations must seek change in order to adapt to environmental changes and achieve better performance. However, despite this obvious statement, empirical analysis has been almost non-existent due to the difficulty of manipulating organizational performance or change. In this study, we overcame these limitations and analyzed the causes and effects of organizational change by assuming a professional sports team as a venture company, which is relatively easy to objectively measure and evaluate organizational change or performance. We systematically collected and preprocessed traditional and advanced metrics of National Basketball Association (NBA) statistics along with preprocessed trade data from eight years of regular seasons (2014~2015-2021~2022) to analyze our research model. Assessment of process macro model 7 derives the following empirical result. The results of the empirical analysis depict that NBA teams with low organizational performance in the previous season are more likely to make organizational changes through player trades to improve performance. Into the bargain player trades mediate the static relationship between the winning percentage in the previous season and the winning percentage in the current season. However, the indirect effect of a team's previous season's performance on player trades appears to vary depending on the current situations and context of each NBA team. Teams that made the playoffs in the previous season tend to make fewer trades than teams that did not and the previous season's performance is highly correlated with the current season's performance. On the other hand, teams that did not make the playoffs in the previous season tend to make a relatively larger amount of player trades in total, and the mediating effect of trades vanishes in this case. In other words, teams that did not make the playoffs in the previous season experience a larger change in performance due to trades than teams that made the playoffs, even if they achieved the same winning percentage. This empirical analysis of the inverse relationship between organizational change and the performance of professional sports teams has both theoretical and practical implications in the field of sports industry and management by analyzing the fundamentals of organizational change and the performance of professional sports teams.

  • The need and rationale for public participation in science and technology is widely acknowledged in academic communities and policy circles. In addition to institutionalized forms of participation, some STS researchers have paid attention to spontaneous forms of public participation, particularly with regard to social movement. This paper aims to explore a new form of public participation, which had been relatively neglected in STS studies. For this purpose, in this paper we examine environmental health issues and cumulative trauma disorders (CTDs) debates as examples of doing "undone science" in Korea. Our focus will be specifically on how environmental organizations and trade unions have both succeeded in making those issues as research and policy agenda for both scientific community and policy makers. In a concluding section, a couple of suggestions for further research are proposed.
