  • The purpose of this study was to investigate the kinematic and kinetic changes that may occur in the pelvic and spine regions during cross-legged sitting postures. Experiments were performed on sixteen healthy subjects. Data were collected while the subject sat in 4 different sitting postures for 5 seconds: uncrossed sitting with both feet on the floor (Posture A), sitting while placing his right knee on the left knee (Posture B), sitting by placing right ankle on left knee (Posture C), and sitting by placing right ankle over the left ankle (Posture D). The order of the sitting posture was random. The sagittal plane angles (pelvic tilt, lumbar A-P curve, thoracic A-P curve) and the frontal plane angles (pelvic obliquity, lumber lateral curves, thoracic lateral curves) were obtained using VICON system with 6 cameras and analyzed with Nexus software. The pressure on each buttock was measured using Tekscan. Repeated one-way analysis of variance (ANOVA) was used to compare the angle and pressure across the four postures. The Bonferroni's post hoc test was used to determine the differences between upright trunk sitting and cross-legged postures. In sagittal plane, cross-legged sitting postures showed significantly greater kyphotic curves in lumbar and thoracic spine when compared uncrossed sitting posture. Also, pelvic posterior tilting was greater in cross-legged postures. In frontal plane, only height of the right pelvic was significantly higher in Posture B than in Posture A. Finally, in Posture B, the pressure on the right buttock area was greater than Posture A and, in Posture C, the pressure on the left buttock area was greater than Posture A. However, all dependent variables in both planes did not demonstrate any significant difference among the three cross-legged postures (p>.05). The findings suggest that asymmetric changes in the pelvic and spine region secondary to the prolonged cross-legged sitting postures may cause lower back pain and deformities in the spine structures.

  • Changes of component(amino acid, free sugar, fatty acid and mineral) and antioxidant effect by pickling of soybeans we.e investigated. Soybean cultivars, Daewon, Pungsannamul, Hwaeum(yellow bean), Ilpum Black and Zynuni(black bean) were soaked in persimmon vinegar for 10 days at $20^{\circ}C$. The major amino acids of raw soybeans were glutamic acid, aspartic acid, lysine and leucine. The content of total amino acid decreased by pickling. The major free sugar of raw soybeans were glucose, fructose and sucrose. Sucrose decreased and glucose and fructose increased by pickling. Maltose was found only in pickled Daewon and Ilpum Black. Linoleic and linolenic acid content of raw soybeans were $49.3%{\sim}57.1%\;and\;7.8{\sim}8.9%$, and the fatty acid contents did not change by pickling. The major mineral elements were K, P and Mg, and their compositions except for Na did not change by pickling. Total phenolic compound, vitamin $B_1$ and C content increased during pickling. The antioxidant effects, electron donating abilities, nitrite-scavenging abilities increased by pickling.

  • The aim the this paper is to explore the processes of three Korean consumer electronics chaebols'entries into, and exits from tile EU in the context of European integration and enlargement and at the global, regional(EU), national and local level. Korean FDI in the EU has increased sharply since the late 1980s, while interacting with the processes of European integration and enlargement. In particular, the chaebols'FDI was caused by reactions against the intensification of Euro-trade regulations. As a result, these defensive entries have led such chaebols to create a strategy of ‘defensive Europeanisation’through the formation of forward and backward linkages between chaebols’affiliates and Korean suppliers within the EU. Nonetheless, defensive FDI has given rise to exits through active relocation within and outside the EU, since the ‘late 1980s’due in the main to (1) sensitive reactions against changing EU trade regulations and (2) failures to maintain cost-competitiveness in particular host regions. Along with these trends, chaebols’entries and exits are placed in contingent and paradoxical structures of the global -regional - national-local nexus, which has resulted from the mismatch of different EU policies such as trade, inward investment and regional policies.

  • The wetlands are facing environmental changes such as desiccation that occurs with the passage of time and reduced ecosystem services from wetlands in the city. In order to maintain the ecosystem services provided by wetlands in urban areas, a system thinking about the trade-off phenomenon of ecosystem services occurring as the wetlands undergo environmental changes is needed. Therefore, the purpose of this study is to develop strategies for wetland design using system thinking approach to enhance the resilience of ecosystem services degraded by the desiccation of wetlands and other disturbances. The objectives of this study include the system boundary and variables. Second, analyzing the dynamics of wetland design strategy. Third, it analyzes the trade-off phenomenon of ecosystem services in terms of the hydrology, hydric soil, and plants strategies to mitigate these effects. Fourth, wetland basic design to improve the resilience of ecosystem services. A wetland in Abuk-Mountain Neighborhood Park, Miryang-si, Gyeongsangnam-do, has been selected as a case study. Causal loop diagrams(CLDs) are used to analyze feedback in the wetland regime. In summary, hydrology, hydric soil, and plants is suggested as system boundaries to design plan. Design strategies for the wetland focused on robustness, redundancy, rapidity, and resourcefulness as a result of CLD analysis are first proposed in order to effectively maintain the wetland regime over the long term. Secondly, in a section related to hydrology, the CLD results show the trade-offs between provisioning-cultural services and regulating services. In order to control these services, a "water cycling system" has been implemented due to its strength in terms of robustness. The CLDs for hydric soil showed the trade-offs between regulating services and supporting services. An "installation of storm drainage for maintaining water levels" was selected due to the strength offered in terms of redundancy and rapidity. The CLDs for plants showed the trade-offs between provisioning - cultural services and regulating services. In order to control the strategic points, the "planting of indigenous vegetation" was suggested given the strength in terms of redundancy. In this study, a wetland design method is proposed that can improve the resilience of wetland ecosystem services by analyzing the dynamics overtime. The results of this research can theoretically be applied to help restore ecosystem services in wetlands using ecological landscape design. In addition, this study will contribute to reducing maintenance costs by improving wetland resilience.

  • A traditional garden in Korea has diverse cultural, historical values, such as the then phases of the times, life phase, culture and art, etc. because it was developed on the basis of the harmony between nature and artificial structures. However, in reality, it's urgent to do efficient, continuous maintenance of traditional gardens which are being damaged and lost due to the problems like an owner's aging, inheritance, and lack of management, etc., especially in case of private property which was designated as a cultural property among such traditional gardens under the Cultural Properties Protection Law. Accordingly, this study conducted this research in a bid to use these research results as basic evidentiary materials for suggesting directivity in introduction of park planning of traditional gardens in folk houses in the near future by implementing the case investigation of transformation into public parks from traditional private gardens in Japan, which is putting the newly introduced park planning to efficient use, together with its systematic management, and the survey on domestic traditional gardens in folk houses status, as well as the hearing-based survey on a traditional gardens in folk houses owner's level of willingness to accept the introduction of parking planning. As a result, this study could confirm that in case of traditional gardens in Japan, they are mobilizing the revenue from admission fees for traditional gardens maintenance by incorporating the main entity of possession, and Japan is promoting transformation of traditional gardens into parks on the basis of use and preservation through the connection with local governments and research institutes. In addition, as a result of surveying domestic traditional gardens in folk houses, it was found that most of the garden owners had hardships in its management, and they were positive about systematic maintenance of gardens through park planning.

  • The meaning and application of 'lesion corporelle' in the context of a variety of mental or psychic injuries is less clear, while there is very little disagreement about its literal translation. U.S. Court decisions since Floyd allow recovery for a range of claims involving emotional injury under Article 17; in some cases there is no recovery, while in others there is full recovery, depending on the allegations and the nexus between the alleged injury and any related or accompanying physical injury. Courts are in agreement that pure emotional injury is not compensable under the Convention. Most courts agree that emotional injury is not compensable in those cases where it has resulted only in physical manifestations such as weight loss or sleeplessness. At the same time, most courts generally agree that emotional injury is compensable if it proximately flows from a physical injury. The issue as to whether the courts would associate PTSD with bodily injury as envisioned in the present Warsaw structure or even the new regime reflected in the Convention proposed by ICAO would largely depend on the extent to which courts would be ready to embrace the compelling scientific findings with regard to mental distress and its application within the term 'bodily injury'. Taken together, these points when the current under Article 17 of the Warsaw Convention, 'physical injury' notion of 'mental injury' is to be extended. Of course, the current terms of the Warsaw Convention have been maintaining a precedent for many countries appear to have a statue of the original purpose of the treaty does not contribute to the diffusion. Therefore, in future treaties 'bodily injury', the term 'injury', the term 'personal injury' or 'health undermined' the term should be replaced or revised.

  • This paper reviews the evolution process of global production network(GPN) discourse, from its origin to the recent theorization, namely GPN 2.0. In so doing, the discursive formation of global production networks is introduced in comparison with a competing discourse global commodity/value chains, with particular attention to conceptual and analytical lacunae in the latter. This article also outlines how the global production network perspective has become a useful discursive and practical tool that allows the examination of the nexus of global economy, transnational corporations, and regional development. Subsequently, a theoretical dearth in the approach is discussed in reference to key critiques, and in this context Yeung and Coe's recent theorization GPN 2.0, which is centered on casual mechanisms and network configurations is reviewed. This paper suggests that the theory adequately addresses the problem of casuality lacking in its precedented conceptual framework, and that it helps exploring the formation and evolution processes of varied production networks(including intrafirm coordination, interfirm control, strategic partnership, and extrafirm bargaining) in connection with competitive dynamics and risky environments. As a result of the theorization, the difference between GPN and the chain approaches has become more apparent, and the idea of extrafirm bargaining is particularly important in the differentiation. Extrafirm bargaining is seen to be a comprehensive networking form inclusive of such GPN 1.0 analytical concepts as value, embeddeness, and power, and research attentive to, and engaging with, the extrafirm networks is expected to help transcending the chain governance approaches' analytical excess of interfirm linkages and industry-centeredness.

  • The Korean real estate market currently is experiencing a slowdown due to the global economic crisis which has resulted from subprime mortgage lending practices. In response, the Korean government has enforced various policies, based on intend to deregulate real estate speculation, such as increasing the Loan to value ratio (LTV) in order to stimulate housing supply, demand and accompanying housing transactions. However, these policies have appeared to result in deep confusion in the Korean housing market. Furthermore, analyses for housing market forecasting particularly those which examine the impact of the international financial crisis on the Korean real estate market have been partial and fragmentary. Therefore, a comprehensive and systematical approach is required to analyze the real estate financial market and the causal nexus between market determining factors. Thus, with an integrated perspective and applying a system dynamics methodology, this paper proposes Korean Real Estate and Mortgage Market dynamics models based on the fundamental principles of housing markets, which are determined by supply and demand. As well, the potential effects of the Korean government's deregulation policies are considered by focusing on the main factor of these policies: the mortgage loan.

  • The digital economy has created a new platform-based business model and raised the issue of the international taxation system in line with rapid economic development. Voices of fair taxation have also grown due to tax breaks to countries with low tax rates, problems caused by the gap between traditional and digital companies, and problems of business-oriented taxation systems. As a result, the international movement to lay the foundation for the international taxation system based on the business model suitable for the digital economy has become active. The stances of foreign organizations and countries are different, and the necessity of domestic policy introduction is increasing when cooperation at the international level is needed. This study was conducted to analyze the policy network and to help decision making. The results of the study showed that there were differences among domestic stakeholders depending on the actors. The EU suggested SDP in the long term, Digital Service Tax in the short term, and OECD suggested SEP in the long term. It was found that a careful approach to decision making and an in-depth study of the policy process are necessary.

  • There has been discussions and investigation on the nexus between religion and citizen's supports for suicide attacks and terrorist groups conducting such acts. In terms of the relationship, there were two potent hypotheses attempting to explain the process and mechanism of the relationship: religious belief hypothesis and coalitional commitment hypothesis. previous studies examined these hypotheses have been carried out across different cultural, religious, and political contexts. Until today, however, there are still lack of concrete evidence, which is generated from empirical studies, supportive evidence for any of these hypotheses. Therefor this study aims to investigate the association between religion and popular support for suicide attacks by using a survey data collected from three middle east countries, Egypt, Morocco, and Pakistan. In analysis, a step-wised regression analysis conducted with a set of variety of variables considered to be related with the association. This study found that variables reflecting religious belief hypothesis, such as prayer to God, religious devotion were unrelated to support for suicide attacks. Yet, prayer time predicted reduced supports for suicide attacks. Further, attendance at religious services, thought to enhance coalitional commitment, predicted support for suicide attacks. Yet, it showed negative association with support for suicide attacks. These findings suggest that regular attendance at religious services and regular prayer have combined effects reducing on the willing to support for suicide martyrdom. However, this study findings affirmatively support for neigher religious belief hypothesis nor coalitional commitment hypothesis. Instead, it suggests the needs for further research examination on the relationship as well as corrections of these hypotheses. Finally, Implications for the research findings for preventing suicide attacks are discussed.
