  • Non-manifold topological representations can provide a single unified representation for mixed dimensional models or cellular models and thus have a great potential to be applied in many application areas. Various boundary representations for non-manifold topology have been proposed in recent years. These representations are mainly interested in describing the sufficient adjacency relationships and too redundant as a result. A model stored in these representations occupies too much storage space and is hard to be manipulated. In this paper, we proposed a compact hierarchical non-manifold boundary representation that is extended from the half-edge data structure for solid models by introducing the partial topological entities to represent some non-manifold conditions around a vertex, edge or face. This representation allows to reduce the redundancy of the existing schemes while full topological adjacencies are still derived without the loss of efficiency. To verify the statement above, the storage size requirement of the representation is compared with other existing representations and present some main procedures for querying and traversing the representation. We have also implemented a set of the generalized Euler operators that satisfy the Euler-Poincare formula for non-manifold geometric models.

  • Vegetation surveys were performed at 45 plots along 10 highways cut slopes in South Korea. Total floral inventory, species richness and exotic plant percentage were obtained within each plot. Life history and life form of each species appeared were analyzed. Community types were classified using hierarchical cluster analysis and detrended correspondence analysis and non-metric multidimensional scaling were conducted from vegetation matrix. 292 species of vascular plants were discovered and the number of natives and exotics were 226 and 66, respectively. There were no significant differences of species richness and exotic plant percentage between cut slopes and rest areas. Hierarchical cluster analysis indicated five clear vegetation associations in cut slopes and rest areas. Detrended correspondence analysis indicated that species composition of total and native plants were similar along the highway cut slopes whereas exotic plants were distributed differentially along the highway cut slopes. in non-metric multidimensional scaling, the studied sites were more separated from each other on the basis of their species composition than the results of detrended correspondence analysis with respect to total, native and exotic plants. The both ordination represented that exotic plants have not been made uniform yet on cut slopes and rest areas by highway corridor in spite of diverse chronosequences after highway construction termination (1 to 22 years). This study showed that the distribution of species composition in exotic plants was different and localized on cut slopes and rest areas of highway in this representative peninsula area of North East Asia and the invasion of exotic plants can retard the process of plant species homogenization.

  • This essay interrogates the category of the 'global' in the emerging domain of 'global intellectual history'. Through a case study of the Indian social-religious reformer Rammohun Roy (1772/4-1833), I argue that notions of global selfhood and rights-consciousness (which have been preoccupying concerns of recent debates in intellectual history) have multiple conceptual and practical points of origin. Thus in early colonial India a person like Rammohun Roy could invoke centuries-old Indic terms of globality (vishva, jagat, sarva, sarvabhuta, etc.), selfhood (atman/brahman), and notions of right (adhikara) to liberation/salvation (mukti/moksha) as well as late precolonial discourses on 'worldly' rights consciousness (to life, property, religious toleration) and models of participatory governance present in an Indo-Islamic society, and hybridize these with Western-origin notions of rights and liberties. Thereby Rammohun could challenge the racial and confessional assumptions of colonial authority and produce a more deterritorialized and non-sectarian idea of selfhood and governance. However, Rammohun's comparativist world-historical notions excluded other models of selfhood and globality, such as those produced by devotional Vaishnava, Shaiva, and Shakta-Tantric discourses under the influence of non-Brahmanical communities and women. Rammohun's puritan condemnation of non-Brahmanical sexual and gender relations created a homogenized and hierarchical model of globality, obscuring alternate subaltern-inflected notions of selfhood. Class, caste, and gender biases rendered Rammohun supportive of British colonial rule and distanced him from popular anti-colonial revolts and social mobility movements in India. This article argues that today's intellectual historians run the risk of repeating Rammohun's biases (or those of Hegel's Weltgeschichte) if they privilege the historicity and value of certain models of global selfhood and rights-consciousness (such as those derived from a constructed notion of the 'West' or from constructed notions of various 'elite' classicized 'cultures'), to the exclusion of models produced by disenfranchised actors across the world. Instead of operating through hierarchical assumptions about local/global polarity, intellectual historians should remain sensitive to and learn from the universalizable models of selfhood, rights, and justice produced by actors in different spatio-temporal locations and intersections.

  • Purpose: This study aims to analyze and prove the effect of logistic capability and Total Quality Management practices on Micro, Small and Medium Enterprises (SME) performance directly or mediated by non-financial performance. Research design, data and methodology: This study tested the hypothesis using Hierarchical multiple regression analysis, the method of data collection in this study was using questionnaire, the sampling technique was purposive sampling technique, with SME that has been established for more than 5 years and manufacturing. The data analyzed were 180 respondents using SPSS 25. Results: The findings showed that logistic capability has direct and indirect effects on SME financial performance and has a positive effect on SME financial performance mediated by non-financial performance. While the total quality management practices have a positive effect on SME financial performance mediated by non-financial performance. Thus, companies can achieve maximum financial performance if they invest in developing employee knowledge and concerning on non-financial actions, such as employee satisfaction, innovation and proactively seeking market opportunities. Conclusions: In conclusion, one of the main factors that companies need to consider to improve financial performance is non-financial performance in mediating the effect of logistic capability and TQM practices on the financial performance of SMEs.

  • Purpose: This study aimed to analyze the factors influencing the well-being of middle-aged non-shift female workers using health-determinant models. Methods: This study analyzed data from the fifth Korean Working Conditions Survey (KWCS), involving 5,449 participants. A hierarchical multiple regression analysis was employed to examine the relationships between various factors and well-being. Results: The analysis identified key factors affecting well-being in middle-aged female non-shift workers, including supervisor support, presenteeism, satisfaction with the working environment, autonomy in working hours, support from coworkers, workplace discrimination, occupation, work-life balance, sleep problems, workplace size, weekly work hours, and sickness absence. This study confirms that the well-being of middle-aged non-shift female workers is influenced by factors at the individual, social, and community levels as well as by conditions related to love. Conclusion: To enhance the well-being of middle-aged female non-shift workers, it is essential to reinforce positive factors such as support from coworkers and superiors. Additionally, addressing and mitigating negatively influencing factors such as workplace discrimination and sleep problems is crucial in promoting well-being. By implementing measures to improve these aspects, organizations and policymakers can contribute to a healthier and more supportive work environment for middle-aged, non-shift female workers.

  • 고해상도 위성영상의 다중분광자료만을 이용하여 토지 피복도를 제작할 경우, 낮은 분광해상도와 단일 토지 피복 내에 존재하는 불균질성으로 인해 분류 결과의 정확도가 저하되는 문제가 발생한다. 특히 식생 클래스의 경우 단일 토지 피복임에도 불구하고 절감 특성에 따라 해당 영역 안에 산림, 초지, 농업지역 등이 함께 분류되는 문제가 두드러진다. 본 연구에서는 이러한 문제를 개선하기 위해 광학 영상 기반의 사전분류를 수행한 후 식생으로 분류된 영역에 대해 고해상도 위성영상의 다중분광정보와 SAR 영상 산란 정보를 통합하고 식생을 세분류하였다. 사전 분류와 식생분류는 최대우도 감독분류를 통해 수행되었으며 식생 세분류 결과와 사전 분류결과 중 비식생 클래스의 융합을 통해 계층적 분류 방법을 제안하였다. 제안 기법은 SAR 영상이나 GLCM 질감 정보를 영상 전체에 걸쳐 단순 통합한 분류결과뿐만 아니라 GLCM 질감 정보를 식생 지역에 적용한 계층적 분류결과에 비해 높은 정확도를 보였으며 특히 식생과 비식생의 분류 정확도가 모두 높게 나타났다.

  • 본 연구는 징병제가 존재하고 한국과 사회적 역사적 유사성이 두드러지지만, 한국과는 달리 위계적 대학문화에 대한 증상이 거의 없는 대만과 대학생문화에 대한 양적 질적 비교를 병행하였다. 이런 비교조사와 분석을 통하여 한국대학의 위계적, 성차별적 군대문화의 현황을 좀 더 명확히 짚어내고 원인을 파악하려 노력하였다. 비교 연구 결과를 보면 대만의 대학문화는 한국보다 위계적이지 않고, 위계문화의 필요성에 대한 지지도가 낮았다. 폭력이나 단체기합등 군대문화적 요소는 주로 한국대학문화에서만 나타났고 남성중심적 술문화와 성매매문화의 지배력도 한국에서 더 강한 것으로 확인되었다. 대만과 한국의 대학문화의 이러한 차이를 낳는 사회 역사적 원인을 살펴보면 대만이 한국보다 위계적 집단주의 문화의 근거이고 원동력이라고 할 수 있는 국가주의적, 군사주의적 국민의 내적 동의나 뿌리가 약하다는 점을 들 수 있다. 대만 대학문화가 상대적으로 덜 위계적인 가장 중요한 직접적 원인은 징병시기에서 찾아볼 수 있다. 한국은 일반적으로 재학중 군대를 다녀오지만 대만은 대학을 마친 후 군대를 다녀오는 것이 일반적이다. 한국의 대학문화에서 군유경험자는 폭력성이나 위계문화 또는 술문화에 큰 영향력을 행사하는 존재로 확인되었다.

  • This study examined the effects of family environmental variables and parent-child communication on the self-esteem of delinquent and non-delinquent juveniles. For this study, a questionnaire was administered to 117 non-delinquent juveniles living with their parents as high school students and 98 delinquent juveniles aged 15~18 who live in detention centers for adolescence. The data was analyzed using t-test, cross-tab, correlation, and hierarchical multiple regression analysis with SPSS /PC window program. Based on these results, the following conclusions were drawn. First, it was found that non-delinquent juveniles show a more open communication style with their parents than delinquent juveniles. Furthermore, a high level of parent-child communication was associated with high self-esteem in adolescents. Second, although physical environment such as family type or economic status influences an adolescents' self-esteem, the degree of positive parent-child communication style has a much greater effect on an adolescents' self-esteem. Finally, in terms of the effects of family environmental variables and parent-child communication style on self-esteem, parent-child communication style has a stronger effect on delinquent juveniles than non-delinquent juveniles. These results shows the importance of communication style between parent and child, especially for families with delinquent juveniles.

  • The purpose of this study was to find out effect of problem solving by mental demand of items and chunking level of problem solver on the item. The principal findings of study were as follows ; 1) According to increase of mental demand of items. students' achievement score appeared to decrease and the more mental demand an item needed. the higher or at least the same hierarchical item was. These results showed that mental demand of item was main factor which decided difficulties of problem solving. 2) Though items have the same mental demand. students' achievement score were different between balance beam task and 2nd law task (achievement score of balance beam task < achievement score of 2nd law task). 3) Achievement score of LM group who used chunked knowledge to solve balance beam task were higher than non LM group who used non chunked knowledge. 4) The level of chunked knowledge was different between two tasks when non LM group solved items of two tasks. On the other hand, LM group used the same level of chunked knowledge to solve items of two tasks. 5) Achievement score of non LM group was the same between items of two tasks after treatment due to chunking effect by treatment. But achievement score of LM group didn't change before and after treatment. The chunking effect by treatment had an effect on non LM group, but it was not on LM group.
