Magic realism, which originated in the culture of Central and South America, creates a fantastic fictional word by linking unrelated incidents using magical. The purpose of this study was to analyze Tarsem Singh's design characteristics that are based on magic realism in his movies, "The Cell" and "The Fall", and to highlight the artistic values appearing in the films. The research was conducted by observing the characteristics and concept of magic realism based on literature and preceding research, and discovering how Singh expressed these creatively and experimentally within the costumes in his films. The results of the study were as follows: Firstly, magical, legendary and symbolic characteristics appear within the fantasy of magical realism, and common techniques within film costuming include repetition of similar objects, solid silhouettes within scenes, and various decorative materials used for fantastic expression. Secondly, regarding ideality, the destruction of previous ideas and recreation of the present were found with materials and details used in film costuming to destroy previous ideas. Expressions of character through external decoration and depiction of living things as not living were also found. Thirdly, reiteration showed the coexistence of history and legend, reality and fantastic elements, and arrangement of opposing elements.

The energy efficiency of a self-powered wireless sensing system for pressure monitoring in injection molding is analyzed using Bond graph models. The sensing system, located within the mold cavity, consists of an energy converter, an energy modulator, and a ultrasonic signal transmitter. Pressure variation in the mold cavity is extracted by the energy converter and transmitted through the mold steel to a signal receiver located outside of the mold, in the form of ultrasound pulse trains. Through Bond graph models, the energy efficiency of the sensing system is characterized as a function of the configuration of a piezoceramic stack within the energy converter, the pulsing cycle of the energy modulator, and the thicknesses of the various layers that make up the ultrasonic signal transmitter. The obtained energy models are subsequently utilized to identify the minimum level of signal intensity required to ensure successful detection of the ultrasound pulse trains by the signal receiver. The Bond graph models established have shown to be useful in optimizing the design of the various constituent components within the sensing system to achieve high energy conversion efficiency under a compact size, which are critical to successful embedment within the mold structure.

Instrumental observation of earth quakes in KIGAM was first attempted in the earty 1980`s by using 6 portable seismographs in the vicinity of Yang-San Faults. Now twenty-four permanent stations, which are equipped with short-period or broad-band seismometer, are included in seismic research network in KIGAM, including KSRS array station in Wonju which is consisted of 26 bore-hole stations. The seismic network of KIGAM is also linked to that of KEPRI(Korea Electric Power Research Institute)which is consisted of eight stations installed within and around the nuclear power plants. Owing to real-time data acquisition by telemetry, it became feasible to automatically locate hypocenters of the local events within fifteen minutes by computer data processing system, named KEMS(Korea Earthquake Monitoring System). Results of the hypocenter determination, together with observational data, are compiled and stored in the data base system. And they are published via web site whose URL is http://quake.kigam.re.kr KIGAM is also running t재 permanent geomagnetic stations installed in Daejun and Kyungju. The observed geomagnetic data are transmitted to Earthquake Research Centre in KIGAM by seismic network and compiled for the purpose of earthquake prediction research and other basic geophysical research.

The amount of information increases rapidly when working in a distributed environment where multiple collaborative partners work together on a complex product. Today's PDM (product data management) systems provide good capabilities regarding the management of product data within a single company. However, taking into account the variety of systems used at partner sites in an engineering environment one can easily imagine problems regarding the interoperability and the data consistency. This paper presents a concept to improve the workflow management using the parameters network. It shows a parameter driven engineering workflow that is able to manage engineering task across company boarders. We introduce a mechanism of workflow management based on the engineering parameters and an architecture of the distributed workspace to apply it within a PDM system. For a parameter mapping between CAD and PDM system we developed an XML-based CATIA data interface module using CAA.

A mathematical model is presented to predict the frost properties and heat and mass transfer within the frost layer formed on a cold plate. The model consists of the laminar flow equations for air-side and the empirical correlation of local frost density. The correlation of local frost density used in this study is obtained from various experimental conditions by considering frosting parameters. The numerical results are compared with experimental data to validate the model, and agree well with experimental data within a maximum error of 9%.

MANET has various types of attacks. In particular, routing attacks using characteristics of movement of nodes and wireless communication is the most threatening because all nodes which configure network perform a function of router which forwards packets. Therefore, mechanisms that detect routing attacks and defense must be applied. In this paper, we proposed hierarchical structure attack detection techniques in order to improve the detection ability against routing attacks. Black hole detection is performed using PIT for monitoring about control packets within cluster and packet information management on the cluster head. Flooding attack prevention is performed using cooperation-based distributed detection technique by member nodes. For this, member node uses NTT for information management of neighbor nodes and threshold whether attack or not receives from cluster head. The performance of attack detection could be further improved by calculating at regular intervals threshold considering the total traffic within cluster in the cluster head.

As technology innovation has become a competitive weapon in the globalized era, firms are engaged in the development of new products to gain competitiveness in the marketplace. One of the main phenomena in a firm's effort to enhance technology development activities is the formation of technology strategy, i.e. the formalization of technology development activities within the firm. This paper explores the practice and management of technology innovation in the Korean manufacturing sector. Based on a survey of over 100 manufacturing firms in Korea, it identifies the contemporary practice of technology planning, and also characterizes the types of relationships that exist among participating interest groups for technology strategy formulation within a firm.

It is interesting to locate homogeneous segments within a DNA sequence. Suppose that the DNA sequence has segments within which the observations follow the same residue frequency distribution, and between which observations have different distributions. In this setting, change points correspond to the end points of these segments. This article explores the use of a binary segmentation procedure in detecting the change points in the DNA sequence. The change points are determined using a sequence of nested hypothesis tests of whether a change point exists. At each test, we compare no change-point model with a single change-point model by using the Bayesian information criterion. Thus, the method circumvents the computational complexity one would normally face in problems with an unknown number of change points. We illustrate the procedure by analyzing the genome of the bacteriophage lambda.

Breast cancer is the most frequently diagnosed cancer primarily affecting women and negatively impacting the individuals, families, and the health care system. Despite the well-known benefits of exercise for breast cancer survivors, rate of physical activity declines during adjuvant therapy and may not return to pre-diagnosis levels. In addition, low levels of adherence to exercise have been observed in this cohort. The challenge is to identify strategies that are effective in promoting exercise adherence. Several of the studies use social cognitive theory as a theoretical framework to design exercise interventions that encourage adherence. Within and without this framework, they have implemented interventions within the home and gym-based environments. Strategies used to encourage adherence to exercise programs and which are readily implemented in most situations have included distribution of print materials and pedometers, as well as recommendation from the oncologist. Other strategies that may be less feasible have included provision of trainers, gym memberships, regular phone-calls, and psychologist-lead stress management sessions.
