The purpose of this study was to analyze walking steps to prevent unnecessary energy consuming and prevention of injury from sliding when someone was walking. The questionnaire, high speed video system, E.M.G. system, and force platform system were used to analyze sliding mechanism in biomechanical perspective. Several results were found as following: 1. According to questionnaire regarding sliding, 93.3% of participants have sliding experiences. People have sliding experiences by greasy floor(48.4%) and obstacle (22.5%). Sliding types were found from different kinds of shoes such as sneakers (48.8%) and boots (34.2%). The results were presented as following 44.6% of participants were fall down front direction and 40.3% of people fell down rear side. 2. According to the high speed video system analyzer, step sliding increased with increasing step speed from distance and acceleration speed experiment with 80 steps/min, 100 steps/min, 120 steps/min. Also, the most sliding were occurred with sneakers, boots, and bare feet as order. 3. According to E.M.G. test results, the vastus lateralis M., the vastus medialis m., and the tibialis anterior m. of electric action potential presented strongly when participants fell front, rear, and right side. The vastus lateralis m. and the tibialis anterior m. of electric action potential presented strongly when someone fell left side, but the vastus medialis m. and the gastrocnemius m. of electirc action potential presented as weaker. 4. According to the force platform test results, the most big change of floor antipower of x-axis presented when someone fell the left side. The most of big change of floor antipower of y-axis presented when someone fell down rear side. The most of big change of floor antipower of z-axis presented similarly when someone fell the front, rear, left, and right side.

Network slicing is a relatively recent paradigmthat has become a subject of intensive research. Most of theexisting approaches follow the ETSI NFV MANO model withsome extensions related to multi-domain slicing, slice selection,etc. The framework is a part of the standalone variant ofthe 5G network standardized by 3GPP. However, the currentimplementation of network slicing in 5G has several limitations,especially regarding management and orchestration: The isolationof slice management is not appropriately addressed, the slicetenant management capabilities are limited, and the managementand orchestration centralization raises serious scalability andreliability issues. Moreover, the slice-level operations are notwell-separated from other processes due to a lack of properseparation of concerns. As a result, the overall network slicingarchitecture has complex interactions with many components ofthe 5G network. In this paper, we describe a new framework thatuses an approach to sustain self-managed and self-orchestratedslices. To that end, we propose a modular architecture in whichslices have embedded (in-slice) management and orchestrationsupport, and multi-domain slices rely on multiple slice-agnosticorchestrators. The framework enables the composition of newslices as a combination of single domain-slices in a relativelyeasy, technology-independent manner.

The purpose of this study was to identify the relationship between children's Inferiority and self-esteem during Taekwondo practice. In order to achieve this purpose, 480 subject were selected among participants of Taekwondo activity programs in the Seoul area by using the stratified cluster random sampling method. Out of the 480 questionnaires responded to. only 414 were used for data analyses because 66 were responded to incompletely or incorrectly. The instrument for data collection was a questionnaire in which Inferiority and self-esteem consisted of items identified by Jun(1999) and Jun(1993), respectively. The statistical methods utilized in the study for analyzing the collected data were reliability analysis, descriptive statistics, one-way ANOVA, standard multiple regression analysis and the following results were obtained: First, both Inferiority and self-esteem differ statistically and significantly according to both sociodemographic variables. Second, both Inferiority and self-esteem differ statistically and significantly according to Taekwondo practice. Third, Inferiority statistically and significantly influences self-esteem.

The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows: 1. According to the accumulative distribution rate of racket material, graphite and wood material show better efficiency in case of brachio radialis muscle of male athletes, but the racket material shows no constant efficiency in brachii radialis muscle of female athletes. In case of flexor carpi radialis muscle, wood material provides better efficiency only for male athletes. In case of triceps brachii muscle, wood material gives better efficiency to males athletes and steel material gives better efficiency to females athletes. Especially in case of biceps brachii muscle, neither male nor female athletes are influenced by racket materials at impact. 2. In the muscle load rate according to racket material, wood has the highest muscle active potential and graphite has the lowest active potential. Therefore, graphite is thoght to be better in the efficiency of muscle load rate.

The proportion of smart phones in the mobile life has become an indispensable presence. Activation of these smart phones, one of the driving force App market is showing steady growth in the different day of the new App is being developed. Depending on the activation of these App Market App development platform and drive his big issues are superior to each manufacturer to support App development platform, but the user perspective, is difficult to determine which platform is superior, for developers it comes to fit a variety of OS App require a development platform that does not include verification of the criteria is Free. In this paper, App development platform for smart phones, software quality assessment for the ISO / IEC 9126 smart phone App Development Using the model performance evaluation was devised.

N-Benzoyl-4(5)-nitroimidazole의 가수분해반응에 대한 속도론적 연구

박국애,정윤주,이종팔 東亞大學校 2000 東亞論叢 Vol.37 No.-

The rate constants for the hydrolysis of N-benzoyl-4(5)-nitroimidazole were determined in water at the 25℃ under pseudo first order conditions by uv/vis spectrophotometer. The pH independent reaction and the hydroxide ion catalyzed reaction were observed from pH 6 to 1 and above pH 6, respectively. The D2O solvent isotope effect couldn't observe in the pH independent reaction, that is, k0 H₂O/k0 D₂O 1.0. Activation parameters in the water catalyzed reaction were calculated to △H‡ =12.3 Kcal and △S‡ = -32.6 e.u. respectively. Thus, the water catalyzed reaction is more important to nucleophilic attack to the carbonyl carbon than the protonation of the leaving group In the transition state. Above pH 6 the hydrolytic reaction showers hydroxide ion catalyzed reaction.

서국웅,강영택 釜山大學校 附設 體育科學硏究所 1996 體育科學硏究所 論文集 Vol.12 No.-

This study was to determine the type of spoken material that can be heard best in a noisy environment There were 6 subjects of graduate school students of P. university. Intelligibility were three different types of tests to measure intelligibility in a noisy environment. We needed a radio and desks. The radio located behind them about 12 inches from the back of their head. 1. The length of the word influnced its Intelligibility by the longer the word, the more readily it is correctly identified. 2. The listener is able to identify a long word by hearing portion of it, particularly familiar, highly probable word, whereas missing one syllable of a short word is more likely to prevent the identification of the entire word. 3. Influencing the Intelligibility of speech in noise is the context in which the words are heard. 4. Situations may arise with a noise level so greut that Certain speech sounds may be confused. 5. We have to make good biomechanical listening environment for Intelligibility in a noisy environment. 6. We can prevent a noisy environment to use earplug and to getrid of noisy material
