The Reverse k Nearest Neighbor (RkNN) query is valuable for finding objects influenced by a specific object and is widely used in both scientific and commercial systems. However, the influence level of each object is unknown, information that is critical for some applications (e.g. target marketing). In this paper, we propose a new query type, Ordered Reverse k Nearest Neighbor (ORkNN), and make efforts to adapt it in an on-demand scenario. An Order-k Voronoi diagram based approach is used to answer ORkNN queries. In particular, for different values of k, we pre-construct only one Voronoi diagram. Algorithms on both the server and the clients are presented. We also present experimental results that suggest our proposed algorithms may have practical applications.

The post-processing modules are parts of an integrated system for reinforced concrete structures. This modules are composed of two modules: member design module and calculation report module. The purpose of this paper is to develope modules that increase efficiency and usefulness of an integrated system used reinforced concrete structures design. The development of post-processing modules is necessary for user to design reinforced concrete structures conveniently and quickly. This modules are connected with central database for the benefit of storing amount of input/output data and being used system with little effort. Post-processing modules used Object-Oriented concepts and techniques include identity, classification, polymorphism, and inheritance. Member design module automatically converts no good members into satisfied members by changing section size or reinforcement bar arrangement. This module can be operated both independent member design modules with user input and a part of integrated system with database input. If user operates member design module, calculation report module is created automatically.

In building a shell-based FMS, which is known as one of the top-down approaches in the field of factory automation, we may take a hybrid simulation into consideration. The modeling of a hybrid simulation consists of real physical entities, virtual simulation, and central clock algorithm, etc. to carry out the whole system operation. In this paper, we sow a way to construct a hybrid simulation software system in manufacturing environments. We bring in the object-oriented methodology in system design and it can contribute in dealing with a wide variety of production types and configurations. Some classes such as project, product, process, order, schedule, stage are defined. These are used and tested by implementing a specific LSI circuit assembly line process.

The object of this study was to investigate the effect of food material supply system on productivity in institutional foodservice. This study was examined by food service companies were enlisted under the influence of domestic enterprises, which used central supply system for the central kitchen operation and efficiency food material circulation system. The main result of this study was as follow: According to the analysis of these data, enlargement of efficiency in food utilization was placed at rising of utilization Processing food materials. And resulted in good expectations such as competitive strengthening, quality capacity strengthening and improvement in sanitary conditions from a productivity point of view.

The development of Reinforced Concrete member design modules is necessary for user to design structures easily. The purpose of this paper is to be available for a integrated system used structure design. This module is linked with central database for the benefit of minimizing time of design and user's efforts. In order to minimize memory space, all of data is stored in central database. Member design modules applied Object-Oriented concepts are possible to be reusible, flexible for member functions in classes. This modules can be operated both independent member design modules and a part of integrated system. Sooner or later, this modules will be related to member grouping modules by data.

This paper presents an edutainment robot for young children. The edutainment robot called 'Mon-e' has developed by the Central R&D Laboratory at KT. The main services of the Mon-E robot are autonomous moving service, object card and story book telling service and videophone service. The RFID technology was introduced for easy interface to young children. The face of Mon-E robot is mounted with an RFID reader. The RFID tag is pasted on story book and object card. If you approach a book or an object card to the face of Mon-E, the Mon-E robot recognizes the identified code and plays its service. In autonomous moving, if the Mon-E robot meets obstacles, it moves back and turns left or right or half rotation. In videophone service, if young children approach an RFID card to the Mon-E, the Mon-E can make a call to the specific number, which is contained in the RFID card. The developed Mon-E robot has tested in real world environment and is evaluated young children and their parents. In the result of evaluation, the feeling of satisfaction was high to main services of Mon-E robot.

Although deep learning-based visual image recognition technology has evolved rapidly, most of the commonly used methods focus solely on recognition accuracy. However, the demand for low latency and low power consuming image recognition with an acceptable accuracy is rising for practical applications in edge devices. For example, most Internet of Things (IoT) devices have a low computing power requiring more pragmatic use of these technologies; in addition, drones or smartphones have limited battery capacity again requiring practical applications that take this into consideration. Furthermore, some people do not prefer that central servers process their private images, as is required by high performance serverbased recognition technologies. To address these demands, the object and scene recognition technologies for mobile/embedded devices that enable optimized neural networks to operate in mobile and embedded environments are gaining attention. In this report, we briefly summarize the recent trends and issues of object and scene recognition technologies for mobile and embedded devices.

The object of this study was to evaluate the acute toxicity of lyophilized water extract of Radix Araliae Cordatae (RA) in male and female mice. The extract was administered to female and male ICR mice as an oral dose of 2000 mg/kg (body wt.) according to the recommendation of KFDA Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy, organ weight and histopathology of 12 principle organs were examined. As results, we could not find any mortality, clinical signs, changes in the body weight and gross findings except for increases of hypertrophy of lymph nodes in male RA extracts-dosing group. In addition, no RA extracts-treatment related abnormal changes in the organ weight and histopathology of principle organs except for some sporadic accidental findings. The results obtained in this study suggest that the RA extracts does not cause any toxicological signs. The LD$_{50}$ and approximate LD of RA extracts in both female and male mice were considered as over 2000 mg/kg.

Muscle vibration measurement has long been an unique scientific study, in general, and the direct reaction of animals to feel pain (algesia), either from vascular or muscle contraction, is a complex perceptual experience. Thus this paper proposes a way to measure animal algesia quantitatively, by measuring the changes in muscle vibration due to a pinprick on the surface of the skin of a Spodoptera litura larva. Using the laser optical triangulation measurement principle, along with a CMOS image sensor, linear laser, software analysis, and other tools, we quantify the subtle object point displacement, with a precision of up to $10{\mu}m$, for our chosen Spodoptera litura larva animal model, in which it is not easy to identify the tiny changes in muscle contraction dynamics with the naked eye. We inject different concentrations of formalin reagent (empty needle, 12% formalin, and 37% formalin) to obtain a variety of different muscle vibration frequencies as the experimental results. Because of the high concentrations of reagent applied, we see a high frequency shift of muscle vibration, which can be presented as pain indices, so that the algesia can be quantified.
