Many Korean construction companies have fallen on hard times because the construction business continues to stagnate. Therefore it is necessary to measure the management efficiency for efficient operation and strengthening competitiveness of them in order to survive a difficult situation. This paper proposes a combined ANP and DEA model to analyze the efficiency of the listed construction firms. In order to determine the input and output variables of DEA, the ANP model is applied to evaluate the importance of input and output variables. The benchmarking companies and efficiency value for the construction firms with inefficiency are also provided to improve the their efficiency. The 57 listed construction companies consisted of 36 listed on KOSPI and 21 listed on KOSDAQ are analyzed in this study. The analysis results show that 11 companies whose values of CCR are 1, and 14 firms whose values of BCC efficiency are 1. In additions, the 19 firms have the scalability efficiency. Finally, we test the correlation between efficiency and the stock price.

In action games such as shooting games or platform games, dodging enemy objects is crucial since the player character dies or loses energy when it collides with any enemy object. In this paper, we investigates how the difficulty of these games changes according to the existence of salient objects. Since salient objects attract the player's attention, other non-salient objects may be unattended by the player, resulting in failing to dodge them. We experimented on the influence of salient objects on the difficulty of a game, and found out that the subjects who played the game without salient objects performed better than the subjects who played the game with salient objects. This paper investigates a human perceptual issue that could affect the game difficulty and suggest a potential guideline for game design and planning.

The display industry plays an important role in the entire Korean economy. Few empirical research has analyzed the efficiency of display companies although it is necessary to measure the management efficiency for more efficient operation and more strengthening competitiveness of them. The purpose of this paper is to measure and analyze their efficiency of the Korean listed display companies using a hybrid ANP and DEA model. In this paper, we analyzed the 44 listed companies consisted of 7 listed on KOSPI and 37 listed on KOSDAQ at the end of 2010. In order to determine the input and output variables of DEA, the ANP model was applied to evaluate the importance of input and output variables. The benchmarking companies and efficiency value for the display firms with inefficiency were also provided to improve the their efficiency.

The purpose of this study was to examine the trend of men's gymnastics on floor exercise final(8 gymnasts) in the 2018 Asian Games through digital video materials. Video recordings of floor exercise final were collected from the 2018 Asian Games. The cross-check with three international gymnastics judges on floor exercise final was analyzed. To fulfil the D-score, 8 gymnasts were the most performed backward saltos elements group(36 elements), forward salto with 1/1 turn(8 gymnasts), backward salto with 5/2 turn(8 gymnasts) and backward salto with 3/1 turn(8 gymnasts). The scores showd average the D score 6.0, E score 7.9, and connection values 0.25. To get a good results on floor exercise, gymnasts need to get a average the D score over 6.0, E score over 8.5, and connection values over 0.3.

Recently, several researches on the development of new economical anchor systems have been performed to support floating structures. This study focused on the group suction piles, which connect mid-sized suction piles instead of a single suction pile with large-diameter. The group suction pile shows the complex bearing behavior with translation and rotation, so it is difficult to apply conventional design methods. Therefore, the numerical modeling technique was developed to evaluate the horizontal bearing capacity of the group suction piles in clay. The technique models suction piles as beam elements and soil reaction as non-linear springs. To analyze the applicability of the modeling, the horizontal load-movement curves of the proposed modeling were compared with those of three-dimensional finite element analyses. The comparison showed that the modeling underestimates the capacity and overestimate the displacement corresponding to the maximum capacity. Therefore, the correction factors for the horizontal soil resistance was proposed to match the bearing capacity from the three-dimensional finite element analyses.

Objective : The aim of this study is to verify the effects of group sensory integrative intervention for sensory motor ability, behaviors in children with developmental delay. Method : The subjects were five children with developmental delays aged between 3 and 5. All Children participated in 26 sessions of group sensory integrative intervention. Children' behavior during testing was observed to assess the sensory motor ability, behaviors, the clinical observation. One group pretest- posttest design was used to verify the effect of group sensory integrative intervention. The observed children' behavior during testing were tested by the Wilcoxon matched-pair signed rank test. Results : There is no significant difference in the clinical observation between pre and post intervention. However, subjects showed the significant difference in Social interaction(Z=-2.121, p=.034), Attention(Z=-2.032, p=.042), total score in Behavior during testing(Z=-2.032, p=.042). Conclusions : The result in this study suggested that the sensory integrative intervention is effective in facilitating the social skills and improving the attention and behaviors. On the other hand, there is no effect in sensory motor ability. It is difficult to generalize the conclusion because the number of the subject was limited and the environmental confounding factors has not been controlled. Therefore, it is needed to supplement these limitations in the future study.

Software industry has put more emphasis on maintenance and enhancement work than on the new development. The existing effort estimation models can still be applied to maintenance projects, though modifications are needed. This paper suggests a way to estimate the size of a maintenance project from the regression analysis of ISBSG's benchmarking data. First of all, among the 3 elements(addition, modification and deletion of the program) which influences the software cost, we selected and classified 4 groups from a total of 8 which shows actual maintenance cost from ISBSG's data. Moreover, we developed statistical model and a model which uses RBF(Radial Basis Function) Network and after evaluating each functions we concluded that the RBF Network is superior to the statistical model.

This study evaluated the efficacy of soluble canine small intestinal submucosa gel in comparison to bovine thrombin in activating rabbit platelet rich plasma (PRP) by detecting growth factors. PRP from rabbits was activated by using soluble canine SIS gel, bovine thrombin, or both. The surface morphology of each group of samples was examined by scanning electron microscopy. The release of transforming growth factor (TGF)-${\beta}1$ from each set of samples was measured over 7 days using enzyme-linked immunosorbent assay. The PRP-canine SIS gel group exhibited the highest total amount of released TGF-${\beta}1$. However, there were no significant differences between any groups. The use of soluble type of canine SIS gel could be an effective alternative to bovine thrombin.

A shared-based tree established by the Core Based Tree multicast routing protocol (CBT), the Protocol Independent Multicast Sparse-Mode(PIM-SM), or the Core-Manager based Multicast Routing(CMMR) is rooted at a center node called core or Rendezvous Point(RP). The routes from the core (or RP) to the members of the multicast group are shortest paths. The costs of the trees constructed based on the core and the packet delays are dependent on the location of the core. The location of the core may affect the cost and performance of the shared-based tree. In this paper, we propose three methods for selecting the set of candidate cores. The three proposed methods, namely, k-minimum average cost, k-maximum degree, k-maximum weight are compared with a method which select the candidate cores randomly. Three performance measures, namely, tree cost, mean packet delay, and maximum packet delay are considered. Our simulation results show that the three proposed methods produce lower tree cost, significantly lower mean packet delay and maximum packet delay than the method which selects the candidate cores randomly.
