An antivirus is a widely used solution for detecting malicious softwares in client devices. The performance of antivirus solutions in the mobile client environment is critical due to its resource constrains. Many solutions light-weighting client's overhead in the mobile client environment have been developed. However, most solutions require platform modifications or software installations and it decreases their realizations in practice. In this paper, we propose a solution detecting malwares on networks using the Software Defined Network (SDN). Our main goal is designing a solution detecting malwares of mobile client without involving the client into the work. We contribute to provide a solution that does not require client-side installations or modifications and so is easily applicable in practice.

Purpose: While most psychiatrists diagnose Hwa-Byung as a chronic psychogenic disorder associated with familial, financial and personality, the purpose of study was to shed light on the nature of Hwa-Byung through pragmatics. Hwa-Byung is characterized as ‘Hwa’ which means fire ‘Byung’ which means disease. This condition cannot be empirically experienced, rather it is represented by suffering internally (in the mind). It also could find an aspect of somatization, and self-diagnosing. Method: As patients themselves diagnose Hwa-Byung, pragmatical approach was taken to analyze the context of the learning through their communication with others. The case examples resulted from in-depth telephone counseling with a client who is housewife with Hwa-Byung over a period of time at the Women's Hot Line. Result: The study showed that the client experienced continuous improper attacks by her husband. She expressed improperness by applying her personal emotions to social-justice reasoning. Conclusion: ‘Hwa’ means lack of mutual intimacy in this research. By expressing this ‘Hwa’, the client would like to recover mutual intimacy with her husband.

Network-based intelligent robot is connected with network system, provides interactions with humans, and carries out its own roles on ubiquitous computing environments. URC (Ubiquitous Robot Companion) robot has been proposed to develop network-based robot by applying distributed computing techniques. On URC robot, it is possible to save the computing power of robot client by environments, has been proposed to develop robot software using service-oriented architecture on server-client computing environments. The SOMAR client robot consists of two layers - device service layer and robot service layer. The device service controls physical devices, and the robot service abstracts robot's services, which are newly defined and generated by combining many device services. RSEL (Robot Service Executing Language) is defined in this paper to represent relations and connections between device services and robot services. A RESL document, including robot services by combining several device services, is translated to a programming language for robot client system using RSEL translator, then the translated source program is compiled and uploaded to robot client system with RPC (Remote Procedure Call) command. A SOMAR client system is easy to be applied to embedded systems of host/target architecture. Moreover it is possible to produce a light-weight URC client robot by reducing workload of RSEL processing engine.

The system implemented in this paper partitions and stores specimen data captured by a light microscope on distributed or parallel systems. Users ran observe images on computers as we use a physical microscope. Based on the client-server computing model, the system consists of client, coordinator, and data manager. Three components communicate messages. For retrieving images, we implemented the client program with necessary functions for educational applications such at image mark and text annotation, and defined the communication protocol. We performed the experiment for introducing a tape storage which stores a large volume of data. The experiment results showed performance improvement by data partitioning and indexing technique.

In early Highlighting the client's personality especially, home design demands very careful consideration. It's not an easy task to understand the characteristics of each family member, to take into account their requirements, and strike proper harmony among them. For this Sampung Apartment Project, I decided to create a cozy homelike atmosphere by using overall modern and antique furniture, props, and lighting. I tried a different sense of space by choosing wood as the main material, installing furniture that looked antique, and applying painting with touch instead of pictures or wallpaper By the use of the light bulb color overall, lighting was yellow and added more comfort. Local lighting was used in certain places to add more fun along with the props. After choosing white as the main color, point colors were determined according to the client's inclination toward green and blue. The color choice also matched the client's paintings that were in soft green and blue. Each room was planned and color coordinated according to their own characteristics. The children's rooms were planned with such point colors as pink, green, and blue. The master bedroom and the family room were produced around gold and grey color, respectively.

Horticultural therapy is a complementary therapy by trained professionals utilizing plant and horticultural activities as media to pursue the positive change of clients, which resulting from stimuli of plant nature, activities, and interaction with other people. Outdoor horticultural activities provide clients with the opportunities of the contact to nature such as fresh air and sunlight as well as plants. But the importance of plant nature to client's health has not been fully acknowledged compared to that of therapist's role and activities in horticultural therapy in Korea. In horticultural therapy it is possible for client to participate on the various levels from passive viewing to active gardening according to the client's ability. Therefore it is necessary for horticultural therapists to consider the therapeutic factors of plant nature to maximize the therapeutic effect of horticultural therapy. The purpose of the research is to clarify the therapeutic factors in the contact of client with plant nature and to emphasize those importance in horticultural therapy. From the review of the experimental researches five therapeutic factors were revealed: Natural light, plant natural view, natural sound, aroma(volatile oils of plants), and plant itself. This paper raises the importance of outdoor activities in horticultural therapy and the necessity for severely handicapped clients to the contact with plant nature, though passively.

Cloud-based streaming game service has numerous merits, but it may suffer from presentation latency in a thin-client. It is an important issue especially for game service which needs instantaneous response to user inputs. This research proposes the methods for reducing the presentation latency between the server unit and the thin-client unit. The approaches proposed to be employed with server unit include the source/sync video format equalization, encoding format configuration according to the media type, and the S/W implementation for transmitting clock periodically. The methods for the thin-client unit include the decreasing the number of instructions, use of light encryption algorithm, and improvement on H/W decoding. The proposed schemes are tested with a commercialized streaming service platform, which reveals the reduction of presentation latency as large as a few hundred milliseconds and reaches the acceptable level (about 100 milliseconds).

The computer generated hologram (CGH) method is the technology which can generate a hologram by using only a personal computer (PC) commonly used. However, the CGH method requires a huge amount of calculational time for the 3D object with a super multi-light source or a high-definition hologram. Hence, some solutions are obviously necessary for reducing the computational complexity of a CGH algorithm or increasing the computing performance of hardware. In this paper, we propose a method which can generate a digital hologram of the 3D object with a super multi-light source using parallel distributed computing. The traditional methods has the limitation of improving CGH performance by using a single PC. However, the proposed method where a server PC efficiently uses the computing power of client PCs can quickly calculate the CGH method for 3D object with super multi-light source. In the experimental result, we verified that the proposed method can generate the digital hologram with 1,5361,536 resolution size of 3D object with 157,771 light source in 121 ms. In addition, in the proposed method, we verify that the proposed method can reduce generation time of a digital hologram in proportion to the number of client PCs.

The growth of mobile devices in Internet of Things (IoT) leads to a number of remote and controlling system related IoT applications. For instance, home automation controlling system uses client system such web apps on smartphone or web service to access the home server by sending control commands. The home server receives the command, then controls for instance the light system. The web service gateway responsible for handling clients' requests attests an internet latency when an increasing number of end users requests submit toward it. Therefore, this web service gateway fails to detect several commands, slows down predefined actions which should be performed without human intervention. In this paper, we investigate the performance of a web server-side platgorm based event-driven, non-blocking approach called Node.js against traditional thread-based server side approach to handle a large number of client requests simultaneously for remote and controlling system in IoT remote monitoring applications. The Node.JS is 40% faster than the traditional web server side features thread-based approach. The use of Node.js server-side handles a large number of clients' requests, then therefore, reduces delay in performing predefined actions automatically in IoT environment.
