The purpose of this study is to analyze the internal meanings of dolls and dolls' images expressed in modern fashion show. Dolls are used as sacred object, decoration object, playing object, personified object or cherished object. The expression types of doll image in modern fashion are as following; substitutes of multi-ego, object of sexual desire, objectified creature, and medium of transcending fantasy. First, dolls image as substitutes of multi-ego had been expressed in magical expression, disgusting mask, transparent mannequin, expressionless, horror, conflict, loss of identity, exaggeration or escapism. Second, as object of sexual desire, dolls image are expressed as naked baby, ambiguous expression, naked body, voluminous body, emphasized specific bodypart, heavy makeup or wax doll of sexy actresses. Third, as objectified creature, dolls are human body in passive form. Human bodies are disassembled and reassembled as dolls. Such dolls reflect serious reality. They wrap up human like product and objectify it. Fourth, dolls image expressed as medium of transcending fantasy recollects youth age or expresses imagination on ambiguous virtual reality. Like this, dolls have value as creatures in various fields of modern fashion. Dolls contribute a lot in creating important inspiration. Dolls also expose internal mentality and represent ego. Externally, dolls express human shape becoming more and more materialized and objectified by advancing scientific technology in digital capitalistic society.

We propose the separation algorithm to simultaneously measure two-dimensional refractive index distribution and thickness profile of transparent samples using three wavelengths. The optical system was based on the Mach-zehnder interferometer with LD (Laser Diode)-based multi-wavelength sources. A LCR (Liquid Crystal Retarder) was used to obtain interference images at four phase states and then the optical phase of the object is calculated by four-bucket algorithm. Experimental results with a glass rod are provided at the different wavelengths of 635nm, 660nm and 675nm. The refractive indices of the sample are distributed with accuracy of less than 0.0005 and the thickness profile of sample was cylindrical type. This result demonstrates that it is possible to separate refractive index distribution and thickness profile of samples in two dimensions using the proposed algorithm.

According to the increasing demand of application software that must be applied to the distributed computing environment, the various tools are proposed to write distributed softwares. But, if using these tools, programmers have to know the usage of each tool requisite for writing distributed softwares. If programmers can write distributed software without additional knowledge, they can get better concentration of the functions of software itself to develop, because it reduces burden for distributed programming. In this paper. we introduce new distributed programming tool, named TORB(Transparent Object Request Broker). With TORB, thanks to programming transparency that is supported by TORB, we can write the distributed software with java more easily. After postprocessing, this software can run in the distributed processing environment that is supported by TORB.

In this paper we present a Distributed Object oriented Virtual computing Environment, called DOVE which consists of autonomous distributed objects interacting with one another via method invocations based on a distributed object model. DOVE appears to a user logically as a single virtual computer for a set of heterogeneous hosts connected by a network as if objects in remote site reside in one virtual computer. By supporting efficient parallelism, heterogeneity, group communication, single global name service and fault-tolerance, it provides a transparent and easy-to-use programming environment for parallel applications. Efficient parallelism is supported by diverse remote method invocation, multiple method invocation for object group, multi-threaded architecture and synchronization schemes. Heterogeneity is achieved by automatic data arshalling and unmarshalling, and an easy-to-use and transparent programming environment is provided by stub and skeleton objects generated by DOVE IDL compiler, object life control and naming service of object manager. Autonomy of distributed objects, multi-layered architecture and decentralized approaches in hierarchical naming service and object management make DOVE more extensible and scalable. Also,fault tolerance is provided by fault detection in object using a timeout mechanism, and fault notification using asynchronous exception handling methods

These days, in order to satisfy the complex and various demands of the customers, the telecommunication networks must provide rapid and flexible services, with the support of efficient service and network management systems. To satisfy these requirements, many objects for management have been released to manage network services and elements. But there are no efficient ways to manage these newly managed objects in object-oriented software. Therefore, we study several problems, when a subsystem using object-oriented technique is implemented. The first problem is that interface works between realized application programs using its technique. The second problem is that reusability of internal managed objects is difficult. In this paper, we will point out some problems and to solve these problems, we have proposed the Object Management System (OMS) architecture, which supports a transparent interface between object-oriented applications and the distributed data repositories. Also in order to manage efficient business objects stored in the different repositories, we suggest a method for integrating dynamic information resources in heterogeneous and distributed network environments. Finally, we applied OMS to TINA(Telecommunication Information Network Architecture) domain, implemented OMS, and verified it with SMV(Symbolic Model Verifier) which is model checking technology.

Since java thread is an object which is treated as independent process within one execution space in the multiprocessing environment, we can use it for independent process of parallel processing. Using thread and synchronization mechanism of java enables us to write parallel application program easily. Therefore, a lot of results are exist which is apply the feature of java that support parallel processing to the distributed computing environment. In this paper, we introduce a system of environment that support parallel execution of thread which is included in legacy java program. The system named TORB(Transparent Object Request Broker) enables us parallel execution of legacy java program after simple converting process, since it support the feature of programming transparency. TORB is extended version of distributed programming tool that is published by our research team. And it had only typical distributed processing feature that is execute a specified function at the specified computer.

This study attempted to make a comparative analysis of dress and architecture to investigate the spatial effect of transparency expressed in fashion. As a result, the following findings were obtained: First, the openness of the space. It means that the human body or the dress inside it can be seen through or the inside space is opened. The volume, form and color of the undergarment seen through this transparent outer garment brings about any change to design. Also, it can be found that the role of the space is further extended as the inside space is seen through outwardly due to the outer garment. Second, interpenetration of the internal and external space. That the human body and the undergarment are seen through due to transparent dress brings about the linkage between spaces and opens the inside outwardly. Third, the briskness of the space. The trait of transparency that exposes the object behind outwardly as it is causes its form and space to be activated and conveys its spatial briskness.

The Non-Contact Optical Sensor using the Hologram Laser for CD Pickup was developed to measure a shape of transparent objects and shown a good performance. Therefore the problems caused by the contact sensor are solved by using the Non-Contact Sensor. The Non-Contact Sensor has to move toward the objects and obtain the Focus Error Signal to measure a position of transparent objects. However, if the distance between the sensor and the object is shorter than the working distance of the objective lens, the sensor will be collided against the objects. In this paper we proposed a new algorithm to estimate the start position of the Focus Error Signal to solve the problems of collision between the sensor and the objects. In addition, we verified that the algorithm is free from the collision in the real time measurement.

The noncontact optical sensor using the hologram laser and automatic power controller is developed to measure a thickness of transparent objects and achieve excellent performance. Due to the contact between the tip of the sensor and the surface of objects, the tip is abraded. In addition the casting glass under high temperature results in extending the size of sensor body. The accuracy of the sensor is degraded due to these reasons. In this paper, to overcome these problems, we proposed a low cost non-contact optical sensor that is composed of a hologram laser unit used for optical pickup of CD player and a plastic lens. Therefore the problems caused by the contact sensor are solved by using the noncontact sensor. The noncontact sensor has to move toward the objects and obtain the focus error signal to measure a position of transparent objects. While the internal temperature of the sensor is controlled under ${\pm}0.1^{\circ}$, many trials shows ${\pm}2{\mu}m$ measurement error as excellent performance.
