Technological Capabilities and Samsung's International Production Strategies in East Asia

Between the late 1980s and the early 1990s, the international competitiveness of the Korean electronics end-product industry declined markedly. This occurred during a period of transition when there was a shift from export to international production. Major Korean electronics firms, newly established as MNCs, were under challenge. The new MNCs had to build technological capability to compete with established MNCs. New MNCs were under challenge in both domestic and global markets and they were confronted by increasing globalisation of production and research and development activities. No new Korean MNC felt the challenge more keenly than Samsung Electronics. This study uses a case study approach to pose questions about which strategies were relevant to success in the international operations of new MN Cs. Of particular interest is the way in which the subsidiaries of Samsung Electronics in the ASEAN region and China maintained their international competitive advantage, and whether their competitiveness can be sustained in the long run. A longitudinal case study approach is used to assess the strategic management, organisational and technology acqusition questions that arise in the establishment and expansion of international operations of new MNC in the electronics industry. The first part of the study provides description of the relationship between the learning and development of Samsung's technological capabilities and the nature of its foreign direct investment and competitive advantage during the 1970s, 80s and 90s. During the 1970s and 80s, Samsung mostly emphasised the development of 'easy-to-imitate capabilities' such as mass production capability, rather than 'difficult-to-imitate capabilities' such as design and product development and international management. Its mass production capability was the main motivation for foreign direct investment, but this is a temporary ownership advantage. The second part of the analysis assesses how Samsung's subsidiaries in the ASEAN region and China established their competitiveness and it can be maintained. The capability to mass produce standardised components, achieving economies of scale, was the source of Samsung's early competitive edge. It had weaknesses in the field of product change, strategic marketing and international management.
NUSAP1 and KIAA0101 downregulation by neo-adjuvant therapy is associated with better outcome and survival in breast cancer.

Background: Studies of molecular changes occurring before and after neo-adjuvant chemotherapy (NCT) for breast cancer may unveil genetic biomarkers to predict therapy response. This study aimed at identifying genomic changes in breast primary tumors of patients under NCT. Gene expression changes were correlated with pathological response and survival.Methods: Gene expression profiles in tissue samples from pre and post NCT were obtained by a non-supervised classification analysis. Thirty-nine patients were classified according to their response to the chemotherapy as pathologic complete responders or non-responders (pCR and no-pCR, respectively). Overall survival was assessed by comparing gene expression values before NCT using the Log-rank (Mantel-Cox) test. Results: A signature constituted by 43 genes was obtained to stratify pCR and no-pCR patients after NCT (FC = + 3, FDR p -value < 0.0298). These genes were involved in regulation of the mitotic nuclear division and the anaphase-promoting complex-dependent catabolic process. Remarkably, over-expression of NUSAP1 and KIAA0101 were associated to poor overall survival. Conclusions: A new expression signature evaluating response for the neo-adjuvant chemotherapy stratified pathological response. The expression levels of NUSAP1 and KIAA0101 before and after the neo-adjuvant therapy may be useful to predict overall survival.
Identification of key positive psychosocial constructs in pediatric and adolescent/young adult patients with cancer: a scoping review.

Introduction. Children and adolescents/young adults (AYAs) with cancer are a vulnerable population susceptible to numerous late effects, such as fatigue and depression, that may diminish their long-term psychosocial, physical, spiritual, and emotional health. A well-rounded understanding of how positive psychosocial constructs affect the quality of care and treatment outcomes is therefore warranted.Methods. We conducted a scoping review of 15 positive psychosocial constructs in children and AYAs with cancer. The primary research questions were 1) what is known about positive psychosocial constructs in children and AYAs with cancer; 2) what value is ascribed to these constructs by patients? Results. 276 articles were included after database search and screening. These studies were mostly observational or qualitative and conducted in North America. Constructs were often poorly defined, and measurement tools used to gather data were wide-ranging. Numerous factors were correlated with increased or decreased expression of certain constructs, but overall themes were difficult to identify. Similarly, patients often spoke of what increased or decreased expression of a construct, with less emphasis on what they implicitly value.Discussion. This scoping review found ample evidence for what increases or decreases expression of positive psychosocial constructs, but this evidence was observational and often conflicting. In the future, we recommend the development of a core set of psychosocial outcomes, with definitions and corresponding measurement tools. We further recommend an emphasis on randomized trials to more rigorously study how expression of constructs can be improved and what effect this has on quality of life.
Speed management

7 SPEED MANAGEMENT – ISBN 92-821-0377-3 © ECMT, 2006 ABSTRACT ITRD* NUMBER E130442 Speeding which encompasses excessive speed (i.e. driving above the speed limits) or inappropriate speed (driving too fast for the prevailing conditions, but within the limits) is dangerous. As well as being a causation factor in around one third of fatal accidents, speed is an aggravating factor in the severity of all accidents. It has also serious consequences on the environment and energy consumption. Speed management can be defined as a set of measures to limit the negative effects of excessive and inappropriate speeds. This report is the output of an expert Working Group which worked over a period of 2 years and conducted an in-depth survey on speed management practices in OECD/ECMT countries. It analyses the effects of speed on safety but also on the environment and the quality of life and assesses the extent of speeding in OECD/ECMT countries. It reviews speed management measures including: infrastructure, signs and signing, vehicle technologies, education and training, enforcement and new technologies, such as intelligent speed adaptation. Finally, it describes how individual measures can be combined in the framework of a speed management policy and highlights the specific needs of developing countries in terms of speed management.

Instrumented gait analysis of stroke patients after FES-cycling therapy.

Background: Functional electrical stimulation (FES) is a modality of motor rehabilitation that consists of the programmed application of bursts of electrical current to the a ected neuromuscular region that aims to improve muscle strength, increase the range of motion, facilitate movement control and decrease spasticity. The present study aimed to measure the changes in gait biomechanics of people with Stroke after a FES-cycling rehabilitation program for the lower extremities. Methods: 39 subjects with chronic stroke received 24 sessions of multi-channel FES synchronized with a cycle-ergometer for the lower extremities. The gait of all subjects was evaluated before and after the intervention by an instrumented gait analysis. Results: Signifcant changes were found in the spatio-temporal parameters of gait, mainly in the speed and stride length when considering the general sample. Additionally, in people under 60 years of age, there are signi cant changes in joint kinematics after FES. Conclusions: The rehabilitation using a multi-channel FES-cycling system for lower extremities improve gait biomechanics in people with Stroke. Trial registration: This study was registered as Instrumental Gait Analysis on People With Stroke After Rehabilitation With a Synchronized FES and Cycle-Ergometer System on July 16, 2020 in Clinical Trials with the identier No NCT04473391 (available at https://clinicaltrials.gov/ct2/show/NCT04473391).

Distribution planning for distributed generation

Distributed generation (DG) is attracting much interest as a means to more economically achieve additional capacity. Traditional distribution planning methods are often inadequate for determining if and when it is economical to consider DG options instead of the more familiar substation and feeder upgrades. New planning methods and computer tools are needed to help the planner better understand the true economic impact of each alternative. This paper describes a methodology for performing distribution planning that also permits the incorporation of such diverse means of improving the capacity and reliability of the system as DG, distribution automation (DA), and demand-side management (DSM).
The Genesis and Development of Mobile Learning in Europe

In the past two decades, European researchers have conducted many significant mobile learning projects. The chapter explores how these projects have arisen and what each one has contributed, so as to show the driving forces and outcomes of European innovation in mobile learning. The authors identify context as a central construct in European researchers’ conceptualizations of mobile learning and examine theories of learning for the mobile world, based on physical, technological, conceptual, social and temporal mobility. The authors also examine the impacts of mobile learning research on educational practices and the implications for policy. Finally, they suggest future challenges for researchers, developers and policy makers in shaping the future of mobile learning.
Propulsion of a microsubmarine using a thermally oscillatory approach

In this paper, motivated by the driving mechanism of a putt-putt toy boat, we explore the feasibility to propel a microsubmarine using a thermally oscillatory approach, which only requires a simple design and does not involve any complicated propulsive systems. We investigate the design, fabrication, actuation and horizontal motions of the corresponding microsubmarines. Based on the understanding gained through preliminary tests on two manually fabricated putt-putt boats, we designed and fabricated the prototype of a microsubmarine. Similar to a putt-putt boat, the prototype also uses a thermally oscillatory process for propulsion. In a cyclic period of this process, due to the expansion and shrinkage of a vapor bubble inside the reservoir of the submarine, liquid is first ejected outside and then sucked into the reservoir. Due to the difference in liquid flow directions between ejection and suction stages, a thrust is produced to propel the submarine. At an applied voltage of 16 V and pulse frequency of 100 Hz, the submarine was found to have the highest speed of 1.8 mm s−1 and longest travel distance of 12.6 mm. The corresponding thrust was estimated to be 67.6 nN.
Thermal Oxidation Stability of Diesel Fuels

Abstract : Injector fouling bench tests(IFBT) and modified Jet Fuel Thermal Oxidation Test(JFTOT, ASTMD 3241) have been used to develop methodology for evaluating the thermal stability of diesel fuels. A new method for measuring the thickness of lacquer-type fuel deposits formed on test surfaces at elevated temperatures has been developed and applied to a variety of fuels, both with and without MIL-S-53021(additive stabilizer package). The utility of this technique greatly expands the capability for exploring and defining diesel fuel thermal stability with respect to both material and kinetic studies. Correlation of IFBT and JFTOT types tests including definitions of temperature, flow, test surface metallurgy and fuel additive effects can now be performed to better understand diesel thermal stability and provide test methodology/test limit information for fuel specification consideration.
Double Chaining Approach for Indirect Monitoring of FMS under Cyclic Scheduling

Abstract The occurrence of failure in Flexible Manufacturing System can deeply modify its performances and its availability. In this context, the monitoring of FMS becomes an important issue, improving production time and minimizing unplanned costly breakdowns. We propose to develop an indirect monitoring by the analysis of product flows at the output of an FMS subjected to a 1-cyclic control. In order to determine the operating system failure that causes the decrease of process performance and the delay observed at the output of a system part, we propose a resolution mechanism based on fault tree analysis.
PERFORMANCE TEST OF LAB SCALE BATCH FOR ROUGH RICE DRYING USING HUSK OF RICE FUEL

The increase in fuel prices and electricity, husk of rice can be used by farmers as alternative energy for rough rice drying. Mechanical drying such as by using batch dryer can be used to overcome the advantage of sun drying especially in rainning season. This research aim to examine the performance of batch dryer lab scale (capacity of 15 kg - 25 kg of grain) with husk of rice fuel. This research was conducted at three variations of thickness which were 15,3 cm, 20,3 cm, and 25,5 cm. The results showed that the average of drying temperature and moisture content for the treatments were respectivelly, 34,78 °C and 13,97%; 34,20°C and 13,77%; 37,92 °C and 13,67%. The higher temperature used the shorter the drying time and the less thick of rough rice the shorter the drying process. The number of rice husk fuel used for the three different thicknesses were 12 kg, 14 kg and 16 kg, respectivelly. Further, the drying durations for each treatments were 10 hours, 11,3 hours, and 12 hours, respectivelly and the drying efficiencies were 3,05%, 3,41%, and 3.63%, respectivelly. One kg of rice husk could be used to dry about 1,35 kg of wet rough rice. Keywords: Rough rice, Batch dryer, Drying, Fuel, Husk of rice.
Security assurance of web services through digital security certification

Service Oriented Computing (SOC) has facilitated a paradigm shift in software provisioning models: software is offered as a service – providing enormous benefits to both service providers and consumers. However, a major barrier for a wider adoption of the new service provisioning model in businessand security-critical domains is the lack of security assurance over such service offerings. Security certification, a well established approach in traditional software provisioning models to gain security assurance, can be applied to service environments to provide service consumers with the required assurance. However, current certification schemes are tailored for traditional software provisioning models where a consumer operates the certified product, static (evaluated at a point in time), and the resulting certificates are represented in natural language. On the other hand, service environments are dynamic with consumers having no control over the service nor its operational environment, and designed to facilitate machine to machine communication. Hence, current security schemes do not scale to service environments, nor can they cater to service specific scenarios such as discovery and composition which rely on automated reasoning. This thesis proposes the concept of a digital security certificate which is realized by a language to enable security certificate representation in a structured, machine-processable manner. In addition, the thesis presents a framework for the maintenance of the digital security certificates that can cope with the dynamic requirements of service environments. The contributions of this thesis will facilitate the adoption of security certification schemes to service environments.
Analysis of dynamic behaviour of rotor-bearing system

This paper deals with a non-linear mathematical model for simulation and analysis of a dynamic behaviour of a rotor-bearing system. The model is used for the simulation of plane motion of a centre of rotor’s cross-section which makes the model convenient for the analysis of vibrations generated in a rolling bearing as well as for the analysis of accuracy of the revolution of rotor supported on a rolling bearing. The model takes into account the following quantities: internal radial clearance, external radial load and unbalanced load. Differential equations of a motion are derived using Lagrange’s equations. The contacts between the balls and the rings are considered to be non-linear with a stiffness derived by the Hertzian theory of an elastic contact. The proposed model enables direct determination of local contact deformations which significantly reduces needed computations and CPU time. The results obtained by the model are used to reconstruct phase-space trajectories and Poincaré maps and to calculate the largest Lyapunov exponent in order to establish the stability of rotor-bearing system motion. A computer program is developed based on the mathematical model for the simulation and analysis of a dynamic behaviour of a rotor-bearing system.
CMOS multiple-valued logic design. II. Function realization

For pt. I see ibid vol. 40, no. 8 p 503-14 (1993). The performance of the set of operators proposed in pt. I is compared with existing sets of operators for the realization of multiple-valued logic (MVL) functions. In pt. I, a set of operators was proposed consisting of literal, cycle, complement of literal, complement of cycle, min, and tsum operators (Set 1). This set of operators is compared to two existing sets of operators consisting of literal, complement of literal, min, and tsum operators (Set 2) and literal, min, and tsum operators (Set 3). For 3-valued 2-variable MVL functions, it is shown that the maximum number of product terms (PTs) required to realize all functions can be reduced to three PTs (using the Set 1 operators) from five PTs (using the Set 2 operators) and six PTs (using the Set 3 operators). In addition, it is shown that the average number of PTs required to realize all the functions reduces to 2.61 (using the Set 1 operators) from 3.19 (using the Set 2 operators) and 3.61 (using the Set 3 operators). It is anticipated that similar improvements are possible for higher valued logic. Realizations of a 4-valued 2-variable function based on different sets of operators are included to support such a claim. >
Computer simulation for pulse compression performance analysis

Pulse compression is a widely used method to maintain the range resolution of radar while increasing the average power per pulse that can be placed on a target. New software was developed which simulates the effects of Doppler shift, additive noise, intrapulse amplitude and phase instability on the compressed radar pulses. In this paper the simulation software tools are described giving some illustrations from the results.
PWM control scheme of resonant DC/DC converter with Class DE inverter and Class E rectifier

A new control method of resonant DC/DC converter with Class DE inverter and Class E rectifier is proposed, which can easily regulate the output voltage for both wide load and line variations while the operating frequency is fixed. It is a pulse-width modulation (PWM) control, i.e., varying the dead time duty ratio of Class DE inverter at a fixed operating frequency. The measured efficiency was over 80% with 2.26 W output power at an operating frequency of 1.00 MHz.
STAR: Situating the Work Experience through Storytelling and Multimedia Techniques

When teaching subtle information such as aviation regulations, there are advantages to providing students with many vantage points to the same body of information. The System for Training of Aviation Regulations (STAR) incorporates multimedia-rich presentations and storytelling techniques within several different learning environments to provide multiple vantage points to the training on aviation regulations. In this paper a description of how these approaches have been incorporated in each of the learning environments, and a summary of an evaluation of the STAR program conducted in November 1995 is presented.
Mechanism of Capacitance Aging under DC Electric Fields in Multilayer Ceramic Capacitors with X7R Characteristics

Capacitance aging under DC electric fields has been studied on multilayer ceramic capacitors (MLCCs) with X7R characteristics. The capacitance change with time was divided into two consecutive stages. The first stage was due to the nonlinear permittivity of dielectrics and it should not be involved in the aging phenomenon. The second stage depended on the MnO content, grain size and firing conditions of the dielectrics. The aging was markedly depressed above the Curie temperature. From the behavior of the second stage, it was concluded that the capacitance aging is caused by the 90° domain switching in BaTiO3 in the core. An equation that represents the aging behavior in the second stage was presented and the mechanism that explains the capacitance aging was proposed. The first stage was due to the nonlinear permittivity and the second stage was due to the domain switching, but the domain switching was also included in the first stage if the domain walls were moved by the first application of a DC field. The change in the aging behavior with the intensity of the DC field could be explained by separating capacitance change into that due to the nonlinear permittivity and that due to the domain switching according to the mechanism proposed in this study. Finally, a methodology for handling the capacitance aging under DC fields was proposed.
System Dynamics and Serious Games

This paper deals with the relationship between serious games and system dynamics. Games have been used in SD since the beginning. However, the field of serious gaming also has its own development. The purpose of this contribution is to provide a broad overview of the combination of serious gaming and SD and discuss the state of the art and promise. We first define serious game, simulation and case study and then point out how SD overlaps with them. Then we move on to define the basic components of a game and continue with an outline of important decisions and challenges of game design. After reviewing different possible purposes of SD-based simulation games, we discuss various approaches to game design with specific attention paid to learning effects. We also review the evolution of the interest for serious gaming in SD over the past 40 years. Our conclusion is that interest has oscillated between rising and declining, but that serious gaming is being recognized as an important component not only in educational settings, but also in policy design. We finish by offering important research questions for the future.
