Most of all the transfer of undertakings in such a service provision business as labour-intensive operation creates uncertainty of employment, aggravates terms of employment and breaks a trade union. However there are no regulations in Korea to protect employees from these undesirable situations. On the other hand Great Britain has introduced the concept of a transfer of undertakings by service provision change in 2006. It was intended to remove or at least alleviate the uncertainties and difficulties created by the need under TUPE 1981 and EU Directive to establish a transfer of a stable economic identity which retained its identity in the hands of the alleged transferee. In contrast to the words used to define transfer in the 1981 Regulations 'service provision change' is a wholly new statutory concept and distinguished from the economic entity. The new provisions seems to be straightforwards and the circumstances in which service provision change is established are clearly set out in Regulations. In this context there is no need for a judicially prescribed multi-factorial approach, as advanced by European Court of Justice like Spijkers test. The new concept of service provision change apply even though there are some minor difference or differences between the nature of the tasks carried on after service provision change as compared with before it. A commonsense and pragmatic approach is required and It is enough only to ask whether the activities carried on by the alleged transferee are fundamentally or essentially the same as those carried out by the alleged transfer. TUPE 2006 of Great Britain far exceeding the scope of the Acquired Rights Directive is full of suggestions as a model of legislation to secure a stable employment itself and favorable and fair conditions of employment. More active efforts are needed for lawmaking to prohibit a dismissal and vary conditions of employment for the reason of the transfer of undertakings itself.

Recently, users' demands for multimedia service are increasing. But, server systems offer inefficient multimedia data service to users. In this paper, to transport multimedia data in the server system more efficiently, we propose the SRTPIO(Special RTP Input/Output) module that process the RTP(Real-time Transport Protocol) data in the kernel with the SIO(Special Input/Output) Mechanism. The SIO mechanism improve a transfer speed because it reduces overheads associated with data copying and context-switching between the user mode and the kernel mode occured in general server system in the kernel-level. The SRTPIO module, integrating the SIO mechanism and the RTP data processing in the kernel, support efficient multimedia data transfer architecture.

Following the increased economic corporations between the South and North Korea, many companies participate the corporation program. They needs insurance policy as a scheme for the transfer of risk from those individual company to it to an insurer. This paper review the possibility of the North Korea insurance authorities and research the origin, history, structure and context of the North Korea insurance law. The North Korea Insurance law differ from the South Korea and China's. North Korea Insurance authority has not capability of doing insurance business both side of underwriting and indemnity. Partly, it caused the uncertainty, insufficient and vague of the insurance law. The writer conclude that the North Korea insurance law faced to the needs of modernization. Especially, the Gyesung Industrial Complex Insurance Regulation couldn't cover the investor and company's risk because it is not based on the nature and basic principles of insurance.

This study investigated the effect of young children's interaction with a teacher and computer environments on their development of representational competence cf replay, the children's ability to construct and reconstruct actions. A pretest-posttest design with one experimental group and one control group was used; quantitative analyses, including interview assessments and coded observations of children's work in the context of educational interventions were supplemented by qualitative analyses of this work. Thirty-nine children (2-5 years of age) were randomly assigned to either an experimental or control group. The educational intervention provided to the experimental group involved a sequence of twenty sessions incorporating a series of three computer environments. A teaching strategy, based on Vygotsky's Zone of Proximal Development (ZPD) and Sigel's distancing theory, was used to mediate children's interaction with these computer environments. Results indicated that children's representational competence kept developing and reached a higher stage and the educational intervention fostered the development of representational competence, with strong evidence of near transfer but no evidence of far transfer. These results suggest that representational competence is a teachable concept and that a complex mediating structure allows children to reconstruct their previous experiences and apply them to problem situations.

Restricted by finite battery energy, traditional wireless sensor networks (WSNs) can only maintain for a limited period of time, resulting in serious performance bottleneck in long-term deployment of WSN. Fortunately, the advancement in the wireless energy transfer technology provides a potential to free WSNs from limited energy supply and remain perpetual operational. A mobile charger called wireless charging vehicle (WCV) is employed to periodically charge each sensor node and keep its energy level above the minimum threshold. Aiming at maximizing the ratio of the WCV's vocation time over the cycle time as well as guaranteeing the perpetual operation of networks, we propose a feasible and optimal solution to this issue within the context of a real-time large-scale deployed WSN. First, we develop two different types of charging cycles: initialization cycles and renewable cycles and give relevant algorithms to construct these two cycles for each sensor node. We then formulate the optimization problem into an optimal construction algorithm and prove its correctness through theoretical analysis. Finally, we conduct extensive simulations to demonstrate the effectiveness of our proposed algorithms.

Mitochondria, fundamental cellular organelles that govern energy metabolism, hold a pivotal role in cellular vitality. While consuming dioxygen to produce adenosine triphosphate (ATP), the electron transfer process within mitochondria can engender the formation of reactive oxygen species that exert dual roles in endothelial homeostatic signaling and oxidative stress. In the context of the intricate electron transfer process, several metal ions that include copper, iron, zinc, and manganese serve as crucial cofactors in mitochondrial metalloenzymes to mediate the synthesis of ATP and antioxidant defense. In this mini review, we provide a comprehensive understanding of the coordination chemistry of mitochondrial cuproenzymes. In detail, cytochrome c oxidase (CcO) reduces dioxygen to water coupled with proton pumping to generate an electrochemical gradient, while superoxide dismutase 1 (SOD1) functions in detoxifying superoxide into hydrogen peroxide. With an emphasis on the catalytic reactions of the copper metalloenzymes and insights into their ligand environment, we also outline the metalation process of these enzymes throughout the copper trafficking system. The impairment of copper homeostasis can trigger mitochondrial dysfunction, and potentially lead to the development of copper-related disorders. We describe the current knowledge regarding copper-mediated toxicity mechanisms, thereby shedding light on prospective therapeutic strategies for pathologies intertwined with copper dyshomeostasis.

Teachers expect team-based project learning to help students develop collaborative and real-world problem solving skills. In practice, however, students tend to solve problems with simple division of labor, and there is a tendency that learning transfer does not occur in solving problems. The purpose of this study is to develop a collaborative learning model based on the transactive memory system (TMS) and to verify its effectiveness. The collaborative learning model based on the TMS is composed of three stages. The first stage is developing TMS. In this stage, the students learn physics concepts and make knowledge about the expertise of group members through peer instruction. The second stage, activating TMS, is building trust through solving well-defined problems for developing near-transfer. And in the third stage, applying TMS, the students solve an ill-defined problem based on real-world context for practicing far-transfer. Based on this model, a 15-week program including two projects on geometric optics and sound waves was developed and applied to 60 college students. The data for five weeks of one project were collected and analyzed. As a result, the TMS of the experimental group with the TMS-based collaborative learning model improved stepwise. Whereas, the difference between the first week and the last week was statistically significant, while the TMS change of the comparison group using the general project learning model was not significant. Also, the experimental group showed that the learning transfer occurred better in the project than the comparison group. A collaborative learning model based on TMS can be used to learn how students gain synergy through collaboration and how students collaboratively transfer the learned concepts in problem solving.

Recently, it has been observed that as the level of Science and Technology in Korea is improving, the demand for technology transfer from overseas buyers is also increasing. A technical value is an important factor for the technology transfer process and the valuation of technology should be performed reasonably. Specifically, a non-economical value has to be examined thoroughly when conducting the valuation for a technology that depends on public values. Since public technology has public benefit as its purpose when compared to technology from the private sector, its discount rate should be appropriately assessed and reflected in its valuation process. In this context, this study presents the methodology of valuation of public technology particularly relating to the transfer of technology from the national defense industries. To be specific, both an application method of the discount rate according to the characteristics and the purpose of the target technology and a qualitative and quantitative evaluation method to reflect the public values are presented. The proposed method for the valuation of defense technology could be used practically both in strengthening bargaining capability based on the reasonably derived technical values for transfer of national defense technology abroad and in the compilation of budgets for technology development in the future.

Public research institutes in Korea have been criticized for attaching great importance to developing new technologies than actively moving them to the industry. Despite the various effort to enhance the technology transfer and commercialization by Korean government and government-funded research institutes, the gap between R&D outcome and real world application does not seem to be reduced. In this context,this study investigates a successful case of TT by a research institute. The aim of this study is to draw the factors of successful and TT which may be applied to other government funded research institute. The finding suggest marketability of technology, commercialization-oriented attitude, technology complementary assets and technological absorption capacity, matching of goals between the partenars and finally the timely utilization of public support program of commercialization are important factors.

We compare insolation results calculated from two well-known empirical formulas (Socket and Beaudry's SB73 formula and the original Smithsonian (SMS) formula) and a radiative transfer model using input data predicted from meteorological weather-forecast models, and review the accuracy of each method. Comparison of annual mean daily irradiance values for clear-sky conditions between the two formulas shows that, relative to the SMS, the SB73 underestimates spring values by 9 W $m^{-2}$ in the northern Adriatic Sea, although overall there is a good agreement between the annual results calculated with the two formulas. We also elucidate the effect on SMS of changing the 'Sun-Earth distance factor (f)', a parameter which is commonly assumed to be constant in the oceanographic context. Results show that the mean daily solar radiation for clear-sky conditions in the northern Adriatic Sea can be reduced as much as 12 W $m^{-2}$ during summer due to a decrease in the f value. Lastly, surface irradiance values calculated from a simple radiative transfer model (GM02) for clear-sky conditions are compared to those from SB73 and SMS. Comparison with iu situ data in the northern Adriatic Sea shows that the GM02 estimate gives more realistic surface irradiance values than SMS, particularly during summer. Additionally, irradiance values calculated by GM02 using the buoy meteorological fields and ECMWF (The European Centre for Medium Range Weather Forecasts) meteorological data show the suitability of the ECMWF data usage. Through tests of GM02 sensitivity to key regional meteorological factors, we explore the main factors contributing significantly to a reduction in summertime solar irradiance in the Adriatic Sea.
