  • This study has as a object to investigate some various meanings of the discourses of postdevelopment of Arturo Escobar with the respect of the social movements of the indigenous and the afro-colombians in the area of the Pacific Coast of Colombia. The ideological lines of Escobar go around the group of critical discourse Modernity/(De)coloniality whose thesis lies on revealing the coloniality as principal elements of the modernity from the XVI century until now culminating in the neoliberal globalization. In another words, they try to seek for the alternative globalization based on the autonomy of the people who has been alienated for long time as 'others' by the eurocentrism of the power and the knowledge and on the equality of the cultural differences o the cosmovisions in Latin America. Escobar concentrates on the fact that the neoliberal regime would turn the nature into the environment considered as the resources for example the traditional knowledges of biodiversity of the indigenous as the capital of the pharmaceutical companies through the patents. However, the indigenous and the afro-colombians have fought fiercely to have them be maintained as a colective right of the possession not only to guard the economic interests but also their proper cultural traditions and the way of life based on the social solidarity of reciprocal care instead of the occidental individualism. This corresponds not only to the social relations but between the nature and the human society. And so, Arturo Escobar interprets these movements not only to defend the places but to express the cosmovisions of Postdevelopment further more the modern paradigm of nation-state.

  • With the advent of the data economy, interest in using big data has increased, but conflicts with protecting personal information have been also steadily raised. In this regard, major countries are accelerating use of big data by exempting de-identified, pseudonymous personal information from protection. However, these policies have been made without the understanding that the economic value of personal information has been actually changing slowly. This paper presents the concept of 'collected information' and defines it as having public interest and therefore, not the exclusive property of the collector of such information. The paper shows the collected information has public interest in terms of personal information protection, connectivity, and universal service and public goods. It also specifies that the 'data governance' cannot be applied to the current data utilization framework that depends upon the holder's consent; rather, it raises the need to improve the practices of information provision consent or provide the beneficiary right of information use to the information holder in order to ensure the proper 'data governance' that will turn market failure into success.

  • With the advent of the 4th industrial revolution, autonomous driving technology is being commercialized in various industries. However, research on autonomous driving so far has focused on platforms with wheel-type platform. Research on a tracked platform is at a relatively inadequate step. Since the tracked platform has a different driving and steering method from the wheel-type platform, the existing research cannot be applied as it is. Therefore, a path-tracking algorithm suitable for a tracked platform is required. In this paper, we studied a path-tracking algorithm for a tracked platform based on a GPS sensor. The existing Pure Pursuit algorithm was applied in consideration of the characteristics of the tracked platform. And to compensate for "Cutting Corner", which is a disadvantage of the existing Pure Pursuit algorithm, an algorithm that changes the LAD according to the curvature of the path was developed. In the existing pure pursuit algorithm that used a tracked platform to drive a path including a right-angle turn, the RMS path error in the straight section was 0.1034 m and the RMS error in the turning section was measured to be 0.2787 m. On the other hand, in the variable LAD algorithm, the RMS path error in the straight section was 0.0987 m, and the RMS path error in the turning section was measured to be 0.1396 m. In the turning section, the RMS path error was reduced by 48.8971%. The validity of the algorithm was verified by measuring the path error by tracking the path using a tracked robot platform.

  • The purpose of this study was to examine the necessity of collaboration between local community and college, and to develop a sport socialization model through the collaboration of local community and college. It's basically meant to create a leisure culture easily accessible to local residents and to suggest some of the right directions for the symbiotic development of local communities and colleges. As for data collection, a data research analysis was implemented by consulting relevant literature and reports, and a content analysis was additionally carried out. The findings of the study were as follows: A sport socialization model was presented to represent the mutual relationship between local community and college by preparing sport socialization programs(a youth sport program and a dementia-preventive exercise program) that were respectively of circulatory relationship type and of reciprocal type. Sport intervention through the collaboration of local community and college(a youth sport program and a dementia-preventive exercise program) serves to accelerate socialization into sport, which leads, in turn, to socialization via sport and then is followed by desocialization from sport.

  • Much has already been learned about what goes on in the minds of second language writers as they compose, yet, oddly enough, until recently little in the L2 research literature has addressed writing and mental imagery together. However, images and imaging (visual thinking) play a crucial role in perception (the basis of mental imagery), in turn, affecting language, thinking, and writing. Many theorists of mental imagery also agree that more than just language accounts for how we think and that imagery is at least as crucial as language. All of these demands, to be sure, are compounded for EFL students, which is why I investigate EFL students' writing process, focusing on the use of mental imagery and its relationship to the writing. First I speculate upon some ways that imagery influences EFL students' composing processes and products. Next, I want to explore how and whether the images in a writer's mind can be shaped effectively into a linear piece of written English in one's writing. I studied two university undergraduate EFL students, L and J. They had fairly advanced levels of English proficiency and exhibited high level of writing ability, as measured by TOEFL iBT Test. Each student wrote two comparison and contrast essays: one written under specified time limitations and the other written without the pressure of time. In order to investigate whether the amount of time in itself causes differences within an individual in imagery ability, the students were placed under strict time constraints for Topic 1. But for Topic 2, they were encouraged to take as much time as necessary to complete this essay. Immediately after completing their essays, I conducted face-to-face retrospective interviews with students to prompt them for information about the role of imagery as they write. Both L and J have spent more time on their second (untimed) essays. Without time constraint, they produced longer texts on untimed essay (149 vs. 170; 186 vs 284 words). However, despite a relatively long period of time spent writing an essay, these students neither described their images nor detailed them in their essays. Although their mental imagery generated an explosion of ideas for their writings, most visual thinking must merely be a means toward an end-pictures that writers spent in purchasing the right words or ideas.

  • This study was conducted to determine the association between weighted needle pinprick sensory threshold(PPT) and sensory nerve conduction studies. The subjects were 53 healthy controls, 31 diabetic patients without peripheral neuropathic symptoms(DM) and 36 diabetic patients with peripheral neuropathic symptoms(DN). PPT was measured on the index and little fingers, bilaterally, as well as under the lateral malleolus, bilaterally. In electrophysiologic assessment the left and right median, ulnar and sural nerves were studied. Mean PPT in DN, DM and controls was high in turn on each sites tested. Age controlled PPT was significantly different among three groups on right little finger(p<0.05) and left malleolus(p<0.05), but on other sites, not statistically significantly different between DN and DM. The results were as follows: Sensory nerve conduction velocity and amplitude on each nerve tested were statistically significantly different among three groups(p<0.05). Correlation of PPT with sensory nerve conduction velocity and amplitude were statistically significant on each site and ranged from -0.4203(left malleolus) to -0.5649(right index finger) and from -0.3897(left index finger) to -0.6200(right index finger), respectively. When electrophysiological study is not feasible, measurement of PPT may be helpful for the assessment of peripheral sensory neurological function.

  • The purpose of this study wa9 to analyse the gait patterns of two female children with hemiplegic cerebral palsy by using the three-dimensional video motion analysis technique. Case 1 has mild spastic hemiplegia on the right side while Case 3 has moderate spastic hemiplegia on the left side. A group of 10, normal female children of the same age(7-8 years old) were selected as the control group for comparison. Time and distance variables as well as the Center of Mass displacement, and the pelvic and joint motions in three anatomical planes were analysed for this purpose. The following observations were made through the analysis : Case 1 revealed an asymmetrical gait pattern in which the step length of the unaffected side was shorter than that of the affected side, which wan a result of the effort to minimize loading on the affected leg by shortening the swing phase of the unaffected leg. Case 1 scored similar phase ratios, cadence and walking velocity to the normal group. A slight posterior tilt of the pelvis was observed throughout the gait cycle. Less hip and knee flexion than the normal group was observed, and demonstrated hyperextension of the knee in the terminal stance phase. The main problem in case 1 originated from the insufficient dorsiflexion of the affected foot during the swing phase. Therefore, Case 1 has difficulty with foot clearance in the swing phase. Usually, this is compensated for by using exessive hip abduction and medial rotation in conjuction with trunk elevation as well as increased vortical displacement of the center of mass. Case 1 revealed a foot-flat initial contact pattern. Case 2 was characterized by a consistent retraction ef the affected aide of the body througout the gait cycle, As a result, an asymmetrical gait pattern with increased stance phase ratios of the unaffected side was observed. In spite of this the step lengths of both sieds were similar. Case 2 scored lower cadence and walking speed than the normal group with lower gait stability. The main problem in Case 2 originated from an excessive plantaflexion of the affected foot which, in turn, rebutted in high hip and knee flexion. Hyperextension of the knee was observed at mid-stance, and execessive anterior tilt of the pelvis throughout the gait cycle was noticed. A gait pattern with high hip abduction and medial circumduction was maintained for the stability in the stance phase and foot clearance in the swing phase. Case 2 revealed a forefoot-contact initial contact pattern.

  • The Highway Capacity Manual(HCM) suggests estimating the average green time for the performance evaluation of the traffic actuated operation and Provides the average green time estimation model. However, the model provides with much room for improvements. This document proposes a new analytical model that overcomes the shortage of the HCM model. The average green times estimated by the HCM model and the proposed model were compared. A computer program using the proposed model was coded for the study, while the ACT348 program was used for the implementation of the HCM model Through the comparison study based on the 1,196 hypothetical simulation data surrogating field data, it was found that the average green times estimated by the proposed model yields much nicer one-to-one linear relationship to the simulation results than the ones from the HCM model in both exclusive-only and shared-permitted cases. The R2 values of the proposed and the HCM models with those cases are 0.90 and 0.56, and 0.86 and 0.57, respectively.

  • Given that the ratio of adolescents among North Korean refugees is increasing, it is the right time to study the present situation of juvenile North Korean defectors. North Korean adolescents tend to find themselves in an uncomfortable situation as they experience unfamiliar lives in South Korea, and act passively in various situations. A proper resolution of such problems in this situation will help them adapt smoothly to South Korean society. This study investigates the relationship between social support, self-esteem, and problem-solving abilities of North Korean adolescent refugees based on a survey on 213 North Korean teens which was performed for 24 days beginning on June 14 2017. The study results show that emotional, material, informational, and evaluative support for North Korean adolescent defectors, which is a type of social support, had a positive effect on their self-esteem, and self-esteem in turn had a positive effect on their problem solving ability. In addition, self-esteem had a mediating effect on the relationship between the four types of social support and problem solving ability of North Korean adolescent defectors. This study suggested a practical plan to improve the problem solving ability of North Korean adolescent defectors for their smooth adaptation to South Korean society, through social support and improved self-esteem of North Korean adolescents, such as program development or self - development training.

  • As it is known, during the Second World War Greece has fought on the side of the allies and the end of the war found the country on the winners' side. However, the struggle for authority right after 1945 was merciless and extremely difficult, as well as dangerous for the course of the country to the future. The political powers were divided between the legal authorities that were represented by the king and formed the exiled government on the one hand and the part of the resistance teams and the rebels of the left that had a soviet friendly direction on the other. Thus, the start of a civil war was just a matter of time. It fin ally started in 1947 and lasted for more than two years. The consequences were disastrous for the country's economy and decisive for the future course of Greece. The national army prevailed with the help of, mostly, the English. Royal parliamentary democracy was established with a clear political turn to the west, as a completion and adaptation of the Agreement of the Great Powers at Yalta. Art had a 'similar' route. Dipolar, contradictory: conservative choices on the one side, and a will for pioneering inspiration and perspective on the other side. The 'dominate' trend was first evident in sculpture and mainly in the public monuments. Their construction aimed mostly at the public propaganda and at the promotion of the sovereign ideology. On the one side we have the public sculptures composed of faces of contemporary heroes or leading figures of the civic war and the national resistance. On the other side we have monumental statues mainly that appeal to a 'public' outside of the country's borders and mostly of the north borders, where there are countries with a communistic regime, like Bulgaria, Serbia and Albania. Their subject is derived from the heroic events of the Balkan Wars (1912-1913) and ancient historical figures like Alexander the Great as the Greek army leader, his father, Philippos II and Aristotle, who was of a north-Greek origin. The political message is twofold: on the one side the 'inner enemy' the communists that were defeated and the promotion of the new liberal social system and on the other side the north neighbours, which not only represent the East Block, but they also conspire the history and the culture of the Greeks. This is the way how the 'Cold War' was resulted in a full and totalitarian expression in art.
