In this study, we divide greenspace in Suwon city into three parts, that is, the conservation part, the maintenance part and the creation part by considering the quantitative aspect of greenspace and the present targets. To do it, two steps are taken. Firstly, assuming that the target year is 2007, the final target of greenspace area is established by combining targets presented in present state survey, the evaluation of resident perception and the future population estimates. The target of greenspace area in present state survey is 7,887,062$m^2$+$\alpha$ and that of greenspace area demanded in the evaluation of resident perception is 8,242,419$m^2$. Demand of greenspace area based on population estimates is 4,227,513$m^2$. When the greenspace needed in the city is added, the target may be more than 8,242,419$m^2$ which is demanded in the evaluation of resident perception. Outcome of the present state survey, 7,887,062$m^2$ + $\alpha$, is considered to be enough to accomodate the greenspace area demanded in the evaluation of resident perception and the population estimates. Therefore, targets of greenspace in Suwon City was established based on the area of greenspace analyzed in the present state survey. Secondly, the target of greenspace is divided into three parts, that is, the conservation part, the maintenance part and creation part. And the methods to attain the target are presented. In order to set desirable targets of urban greenspace, it is necessary to combine the outcome of present state survey, the resident perception, the population estimates and the various urban conditions. If the results of this study are applied to the urban planning or other related planning, the urban ecosystem will be protected and the biotope will be created.

As a main body of a curriculum, a set of sentences stating mathematical contents plays an important role in teaching and learning mathematics. The contents sentences in the $7^{th}$ version, the 2007 version, and the 2009 version of elementary mathematics curricula were analysed. The elementary mathematics curriculum consists of about 200 contents sentences. The final endings of those sentences are the type of ability such as "to be able to ~". The elementary mathematics curriculum would be managed systematically by disassembling and restructuring those contents sentences. We should state students' activities more concretely by varying the final endings in the curriculum.

Recently, various and effective contrast based salient object detection models to focus on a single target have been proposed. However, there is a lack of research on detection of multiple objects, and also it is a more challenging task than single target process. In the multiple target problem, we are confronted by new difficulties caused by distinct difference between properties of objects. The characteristic of existing models depending on the global maximum distribution of data point would become a drawback for detection of multiple objects. In this paper, by analyzing limitations of the existing methods, we have devised three main processes to detect multiple salient objects. In the first stage, regional features are extracted from over-segmented regions. In the second stage, the regional features are categorized into homogeneous cluster using the mean-shift algorithm with the kernel function having various sizes. In the final stage, we compute saliency scores of the categorized regions using only spatial features without the contrast features, and then all scores are integrated for the final salient regions. In the experimental results, the scheme achieved superior detection accuracy for the SED2 and MSRA-ASD benchmarks with both a higher precision and better recall than state-of-the-art approaches. Especially, given multiple objects having different properties, our model significantly outperforms all existing models.

This study was intended to contribute to allowing athletes to raise a technical understanding of two motions of high difficulty such as the Swallow motion and the Nakayama motion and enhance their competitive power by analysing the kinematical factors required to link those two motions on the competitive scene on the rings for current national athletes. For this purpose, the game of the ring event was videotaped for male heavy gymnasts participating in the final elimination match of the 2004 Athens Olympic Games. This study attempted to select the performing motions of the final 1st-and 2nd-place athletes performing the linking motions from the Swallow motion and the Nakayama motion using the DLT(direct linear transformation) method. As a result, it arrived at the following conclusion : A1 properly performed the flexing and extending movements using the angular velocity of the segment and joint as the switching motion using the body at the time of linking the motion from the Swallow skill to the Nakayama skill. A2 was evaluated to perform the skill taking the form of depending on the force at the static state. Therefore, it is thought that A1 should take care of shaking at the time of using the elasticity of the body. It is thought that in case of A2 the proper use of the elasticity of the body take care of shaking at the switching motion while taking advantage of the force will contribute to his competitive power.

Prosthetic-driven implant placement is a concept considering the dental implant restoration first based on the final form of that prosthesis to be restored. The latest development of the imaging technology and digital dentistry was able to be obtained the high quality images of CBCT with low radiation exposure and it has also enabled the process to reconstruct the intraoral state in three dimensions due to the development of the intraoral, model and impression scanner. Computer-guided implant placement simulations and template production was able to be more widely used in this context. In this narrative review, the features and the types of implant surgical guides will be introduced. It will also be described the diagnosis and treatment plan using computerguided implant software to reduce the number of visit and to increase the accuracy of the implant surgery through the top-down approach based on the shape and location of the final prosthesis.

This paper presents a short-term scheduling algorithm for the operation of steelmaking processes. The scope of the problem covers refining of the hot iron transferred form a blast furnace, ladle treatment, continuous casting, hot-rolling, and coiling for the final products that should satisfy the given demand. The processing time at each unit depends on how much the batch amount is treated, and te dedicated intermediate storage with finite capacity between the units is considered. Resource constraints and initial amount of each state are incorporated into the presented scheduling model for the algorithm of on-line scheduling. We propose amixed integer linear programming (MILP) model with two objectives for the scheduling. The first is to maximize the total profit while atisfying the due date constraint for each product. And the second is to minimize the total processing time, makespan, while satisfying the demand for each product. Especially, we observe the effect of penalizing the intermediate storage and the inventory level of the final product on the scheduling results.

For an increased level of productivity, it is important that the end-point of a robot manipulator moves from an initial location to final position in the minimum time subject to the available maximum actuator's torque (or force) at each joints. The main issue is to develop an algorithm to compute the actuators in real-time. In this paper, a digital state feedback control algorithm has bean developed to obtain the near-minimum-time trajectory for the end-effector of a robot manipulator. In this algorithm, the poles of the linearized closed loop system are judiciously placed in the Z-plane to permit minimum-time response without violating the constraints on the actuator torques. The validity of this algorithm have been established using numerical simulations. A three-link manipulator in chosen for this purpose and results are discussed for three different combinations of initial and final station.
