The purpose of this study was to compare kinematic data between experts and novices, and identify difference kinematic parameters changing direction to kick in penalty kick of soccer play. Novice subjects were 5 high school students Who has never been experienced a soccer player, and expert subjects were 5 competitive high school soccer players. The 3-d angle was calculated by Euler's Angle by inertial axis and local axis with three-dimensional cinematography. Kinematic parameters in this study consisted of angles of knee joints, hip joints, lower trunk and upper trunk when the support foot was contacted on ground and kicking foot impacted the ball. The difference of angle of knee joints in the flexion/extension was insignificantly showed below $4{\sim}9^{\circ}$ in groups and directions of ball at the time of support and impact. But the difference of angle of hip joint was significant in groups and directions of ball at the time of support and impact. Specially the right hip joint of experts were more flexed about $12^{\circ}$($43.99{\pm}6.17^{\circ}$ at left side, $31.87{\pm}4.49^{\circ}$ at right side), less abducted about $10^{\circ}$ ($-31.27{\pm}4.49^{\circ}$ at left side, $-41.97{\pm}6.67^{\circ}$ at right side) at impact when they kicked a ball to the left side of goalpost. The difference of amplitude angle in the trunk was significantly shown at upper trunk not lower trunk. The upper trunk was external rotated about $30^{\circ}$ (novice' angle was $-16.3{\pm}17.08^{\circ}$, expert's angle was $-43.73{\pm}12.79^{\circ}$) at impact. Therefore the significant difference of kinematic characteristics could be found at the right hip joint and the upper trunk at penalty kick depending on the direction of kicking.

Support vector regression (SVR) is devised to solve the regression problem by utilizing the excellent predictive power of Support Vector Machine. In particular, the ⲉ-insensitive loss function, which is a loss function often used in SVR, is a function thatdoes not generate penalties if the difference between the actual value and the estimated regression curve is within ⲉ. In most studies, the ⲉ-insensitive loss function is used symmetrically, and it is of interest to determine the value of ⲉ. In SVQR (Support Vector Quantile Regression), the asymmetry of the width of ⲉ and the slope of the penalty was controlled using the parameter p. However, the slope of the penalty is fixed according to the p value that determines the asymmetry of ⲉ. In this study, a new ε-insensitive loss function with p1 and p2 parameters was proposed. A new asymmetric SVR called GSVQR (Generalized Support Vector Quantile Regression) based on the new ε-insensitive loss function can control the asymmetry of the width of ⲉ and the slope of the penalty using the parameters p1 and p2, respectively. Moreover, the figures show that the asymmetry of the width of ⲉ and the slope of the penalty is controlled. Finally, through an experiment on a function, the accuracy of the existing symmetric Soft Margin, asymmetric SVQR, and asymmetric GSVQR was examined, and the characteristics of each were shown through figures.

A fine is defined to the criminal penalty which is slighter than imprisonment on a system of criminal penalty, but put practically a seat to imprisonment and similar strong discipline contrivance to commission agent in capitalism societies be doing. Also, did heavy commission, but the corporation time, a fine to consider the respect which cannot impose other criminal penalty, and cannot but impose fine penalty only to this corporation carries out art as important criminal penalty than the commission which a person does. But fine drawing of our country cannot carry out art scaring to criminal penalty to rich body as aggregate fine drawing, and a lot of, but do abatement duration of a fine so as same, and be most in spite of adjudication criminal sentence occupying at criminal case adjudication, and difference cannot do to an amount of a fine that is carrying well out the art. Therefore, and have to change to the daily fine systemdm which gained because of total fine system in order to carry out value as modern criminal penalty, and a few fines shall exchange to penalty payment system according to complement department canon of Penal Code, and social accusation protects individual information of low commission agent if so, can normally do art accomplishment of criminal penalty. The system that the maximum can guarantee right of defence of accused has to have to be introduced in procedural a few aspect to pronounce this and a fine. Specially, let explain necessary fact to be related to, and informal procedures understand, and introduction of drawing to be able to get from accord of accused is necessary for accused before charging to informal decree in order cannot be guaranteed right of defence this of accused while consisting in writing of whether accusation and adjudication are procedural at informal procedures, and to supplement respect.

The present study aims to analyze kickers' strategic actions for finishing in penalty shoot-outs among youth soccer players ultimately to increase success rates of shoot-outs and to score a victory. Subjects were experienced 271 soccer players attending high schools located around the capital area. To determine any difference in strategic actions for finishing in penalty shoot-outs among the subjects, frequency analysis or chi-square was used for the analysis. The analysis found the following points: First, the success or failure rates of kickers in penalty shoot-outs were found to depend on subjects' experiences as soccer players. Second, in terms of kickers' shooting qualities, they were found to shoot on goal regardless of shooting positions. Third, an important factor to enhance the shoot-outs probability was found to be a strategic action through the eyes. Fourth, in view of the strategic actions prior to kickers' shooting, goalies were found to check out kickers' positions first and estimate the directions and qualities of shooting via kickers' body actions and eye lines.

The impact of optical receiver configuration on in-band crosstalk-induced penalty has been investigated in both theoretical and experimental analyses, for differential phase-shift keying (DPSK) and differential quadrature phase-shift keying (DQPSK) signals. Previously it has been shown that DPSK signals are ~6 dB more tolerant to in-band crosstalk than on-off keying (OOK) signals. However, we find that the tolerance difference between the two signals is reduced to ~3 dB when the decision threshold of the receiver is optimized to minimize the bit-error rate for each signal. Then we derive simple equations for the in-band crosstalk-induced penalty in DPSK and DQPSK signals with two different optical receiver configurations: balanced and single-ended direct-detection receivers. We confirm that the penalties obtained from our simple equations agree well with the measured results.

A large amount of food waste in known to bring about many problems including environmental pollution. This study was carried out to investigate effective methods for reducing leftovers in the food service business & industry. The reasons for producing leftovers in food service restaurants, customers perferences of foods, cooking methods the degree of saltiness, and serving size were surveyed using questionnaire and the menu was improved based on the customers perferences. Excessively large serving sizes and the unfavorable cooking methods is food service were the main reason for the leftovers of side dish and one=dish foods. Because the largest amount of leftover came from soups & stews, an effective way of reducing leftovers in food service would be to reduce the serving size of soups & stews. Total leftovers was reduced to about 60% after improving menu (p<0.01) and the each leftover or rice, soup&stew, and side dishes was also reduced significantly after improving the menu(p<0.001) The environmental campaign to reduced food waste by bulletin intra-net using personal computers slogans& posters, and new letters was conducted for one week each and then leftovers were measured 9 times for following three weeks regularly. The total amount of leftovers decreased slightly due to the environmental campaign, but the difference was not significant . When we adopted penalty or prize system leftovers were decreased by about 35%(p<0.001) and the penalty system was more effective than the prize system in reducing leftover (p<0.001) When we compared the leftovers under the three services, a tray service was more effective in reducing leftover than complete self-service of partial self-service(p<0.001).

The mission of the doctors is to take care of human life, body and health through the medical behaviors such as diagnosis and treatment. Under this job propensity, the doctors have care duty to take the best actions required to prevent the risk according to the patients' specific disease status. Such care duty of the doctor may be evaluated based on the medical behavior level at the medical institution and clinical medical study field. Such medical level should be understood in the normative level, considering the treatment environment, condition and specialty of the behavior, because it means the medical common sense known and acknowledged to the normal doctors. While the criminal suit requires the evidence for no doubt conviction, the civil suit requires more eased different standard. The results between the criminal and civil sentence may be different, because the confirmed former case may lead to long-term imprisonment and even death penalty, while the latter case puts only monetary penalty on the defeated party.

Recently, the Korean government promoted the construction of metropolitan express subway to connect major transportation hub in the metropolitan area within 30 minutes. Most stations of the metropolitan express subway are connected to existing subway stations, so the importance of transfer increased. Although many studies have been conducted on the effect of transfer penalty on route choice, there are few studies on the transfer behavior of the metropolitan express subway. Therefore, in this study, a transfer behavior analysis was conducted on the Shinbundang Line, a representative metropolitan express subway. To analyze the transfer behavior according to the degree of traffic congestion and the presence of fare payment, route choice models were made using transport card data divided according to week, time, and user characteristics. As a result of the analysis, users of the metropolitan express subway had greater disutility to the transfer waiting time compared to the transfer moving time. Furthermore, especially during the peak time, EIVM(Equivalent in-vehicle minutes) of the transfer waiting time was 3.51. In this study, EIVM for metropolitan express subway users were analyzed to be 2.6 minutes, which is significantly lower than the results of previous studies on subways. This suggests that there is a difference in the transfer penalty between subways and metropolitan express subway, and that it is necessary to apply the transfer penalty between subways and express subway differently when forecasting subway traffic demand.

On 2013 the English court delivered a decision that the payment obligation under time charter party is a condition. According to this judgement, The Astra, a breach of the obligation to pay hire on time entitles the owner both to withdraw the ship and sue the charterers for damages for the difference between the contract and market rate for the remainder of the contracted period. On 2015, however, the English court stood at the other side. In Spar Shipping, the court confirmed that the obligation to pay hire is not a condition of the contract but an "innominate term" - from the charterers' breach ship owners can exercise their contractual right to withdraw, but owners' right to sue for damages depends on whether the charterers have deprived the owners of the substantial benefit of the contract, or shown an intention to do so. This article aims to compare both decisions over the points that (1) the importance of on-time payment under a time charter party, (2) as a critical and main question in this article, whether the mattered payment clause is a condition or innominate term, (3) whether the on-time payment clause is merely a penalty or a reasonable liquidated damage. Based on various reasons, I am on a position that the payment of hire is not a condition but an innominate term. Default in punctual payment by a charterer, in the absent of clear contractual agreement, needs to be decided further whether that breach removes the substantial benefit of the contract from the owners.
