European Union unilaterally included the emissions from aviation activities into EU ETS on 19 November 2008 by amending Directive 2003/87/EC. According to the Directive all the emissions(mainly against the CO2) from aviation activities shall be subject to the regulation of EU ETS from 2012. For the period from 1 January 2012 to 31 December 2012, the total quantity of allowances to be allocated to aircraft operators shall be equivalent to 97% of the historical aviation emission s. From 1 January 2013, the allowances will be reduced to 95%. The allocation of allowances which may be applied by each operator with free of charge will be reduced from 85% to 82% from 1 January 2012 to 1 January 2013. Since the Directive will affect every country's airline industry more or less, the nations and international organizations respond variously. The controversial focus is that whether EU has the right to unilaterally include the emissions from international aviation activities into EU ETS. This article firstly analyzes the effect caused by EU ETS to China's airline industry, and then studies the legality of the action of EU subject to current positive international law, and finally draws the conclusion that EU enjoys no such right to unilaterally include the emissions from international aviation activities.

Gait analysis can provide a better understanding of how the alignment of the lower limb and foot can contribute to force observed at the knee. Anatomic and mechanical factors that affect loading in the knee pint can contribute to pathologic change seen at the knee in degenerative pint disease and should be considered in treatment plan. The purpose of this study is to present the gait analysis data and to determine whether there is any relationships between alignment of the lower limb, foot progression angle and knee pint moments in elderly healthy women with 3-dimensional motion analyzer. The results were as follows; 1. Cadence showed 114.8 steps/min, gait speed showed 1.05 m/s, time per a stride showed 1.06 sec, time per a step showed 0.53 sec, single-supporting phase was 0.41 sec, double-supporting phase was 0.24 sec, stride length was 1.04 m, Step length was 0.56 m. 2. According to the parameters of kinematics, the maximal knee flexion angle through swing phase showed left $46.82^{\circ}$, right $40.19^{\circ}$ and the maximal knee extension angle showed left $-1.32^{\circ}$, right $2.01^{\circ}$. knee varus showed left $26.90^{\circ}$, right $30.93^{\circ}$. 3. Moment, one of kinetic parameters of knee pint the maximal flexion moment showed left 0.363. Nm/kg, right 0.464 Nm/kg and maximal extension moment showed left 0.389 Nm/kg, right 0.463 Nm/kg. The maximal. adduction moment showed left 0.332 Nm/kg, right 0.379 Nm/kg and the maximal internal rotatory moment showed left 0.13 Nm/kg, right 0.140 Nm/kg. 4. On sagittal plane, the maximal power of knee joint showed left 0.571 J/kg, right 0.629 J/kg. On coronal plane, the maximal power of knee joint showed left 0.11 J/kg, right 0.12 J/kg. On transverse plane, the maximal power of knee joint showed left 0.058 J/kg, right 0.072 J/kg. 5. The subject who had varus alignment of the lower extremity had statistically higher in knee adduction moment in mid stance phase. 6. The subject who had large foot progression angle had statistically lower in knee adduction moment in late stance phase. A relationship was observed between the alignment of the lower extremity and the adduction moment of the knee joint during stance phase. Hence, we need some research to figure, out the change of adduction moment according to the sort of knee joint osteoarthritis and the normal geriatrics as well. And we also require more effective, specific therapeutic program by making use of those background of researches.

This paper is to inquiry into the conceptual model of religious education in school curriculum focused on 7th revised curriculum, subject matter and teacher training system. We have to consider the related variables for the operation of school curriculum: student, school, teacher. In school curricula of Korea, religious education can be practiced as a elective course of subject, discretion activity and special activity, latent curriculum etc. And also it should be considered student's right of option and autonomy of private school, because at least those are the important variables effect upon the religious education in school curriculum. Now I'd like to abstract results of this paper as followed. First, it should be considered student's right of option for religious education in private school curriculum. But at this case, also under the name of education it should be justified precondition of purpose, content, approach method. If not, it easy to access to pejorative meaning as a religious indoctrination. Second, in case of conflict between student and school, I think that a proper method is to adjust the related variables. Third, if the purpose of religious education in school based on religiosity, it can be cover the understanding of religious culture, affectionate domain of religiosity, behavioral religiosity. Finally, in order to accomplish such an conceptual model of religious education in school, it should be set a condition for teacher training system, subject matter etc.

The purpose of this study was to investigate the contributions of body joints to the kinetic energy of the clubhead in the golf swing. Three dimensional swing analysis was conducted on the seven KPGA golfers. The subjects were asked to swing with 45 inches of driver. The work done by body joints were computed by utilizing the inverse dynamics method. The order of work done by the body joints was lumbar > left hip > right shoulder > left wrist > right wrist > right hip at the first phase. At the second phase, the order of work done by the body joints was trunk > left elbow > right wrist > right shoulder > left wrist > right wrist. At the third phase, the order of work done by body joints was lumbar > right shoulder > left shoulder > left elbow > right wrist > right elbow. The sum of the work done by the body joints was lumbar > shoulder > wrist on the average. The kinetic energy of the club head was 430.11${\pm}$24.35 J and the subject's swing efficiency was shown as 31.82${\pm}$4.86% on the average. The contributions of body joints to the kinetic energy of the clubhead was the order of lumbar > upper right shoulder > left elbow > right wrist during the down swing.

Background and Objectives: The present study aimed to compare thresholds of direct bone-conduction (BC direct) with those of behaviorally measured BC pure-tone audiometry (PTA) and objectively measured BC auditory brainstem response (ABR) to confirm the clinical feasibility of their relationships. Subjects and Methods: Young adults with normal hearing participated in the study to determine the thresholds from three measurements at four testing frequencies. In the BC direct, the vibrator of a bone-anchored hearing aid softband was placed on the right mastoid of each subject. In both PTA and ABR, a B71 bone oscillator was placed on the subject's right mastoid. While the subject's thresholds of BC direct and BC PTA were determined with a clinically routine 5-dB step procedure, BC ABR was conducted to determine the individual's hearing sensitivity by a peak V of the waveform using tone-burst and click stimuli. Results: The BC direct showed a different pattern between low and high frequencies. Precisely, its thresholds were 13.25 and 12.25 dB HL at 0.5 and 1 kHz, respectively, but 19 and 19.75 dB HL at 2 and 4 kHz, respectively. A significant positive correlation existed between BC direct and PTA at 1 kHz, which was also correlated with ABR. Conclusions: Based on the current data, the thresholds of BC direct were similar to BC PTA at low frequencies and BC ABR at high frequencies. The thresholds of BC direct might be predictable at approximately 5 dB higher (or lower) than that in PTA, although a large data set is required for standardization.

Biophotons from three healthy subject's hands were measured every Friday for one year. The correlation coefficients between the left and right palms were found to be 9.0, and a similar value was also obtained between the left and right back of hands. However, the correlations between the palm and back of a hand turned out to be low, on the average only 0.5. These results are consistent with the result of Zhang's $CO_2$ production rate experiments on the acupuncture points. The high correlation between the left and right, and the low correlation between the palm and back are interpreted according to the acupuncture theory of meridians. The palm and the back correspond to the yin and yang meridians, respectively. And their behaviors are rather opposite, thus they show low correlations.

Purpose: At acupoint pressure, the pressing direction of all acupoints is usually vertical. However, it is not clear whether the vertical direction is toward the belly button or the body's center in the BL52. In this study, the effective direction of acupressure was studied by measuring the pressure pain threshold according to the direction of acupressure in 30 subjects. Methods: The distance from the subject's GV4 to the left and right BL52 and the distance from GV4 to the navel were measured, and then using the ellipse where the left and right BL52 of GV4 pass through the navel, the angles of the navel direction and the body's center were calculated in the left and right BL52. The pressure at the time when the subjects felt pain while pressing the BL52 in two directions was used as the acupressure pain threshold. The pain threshold was measured 3 times at 3 minute intervals on the left and right BL52s of the subject. Results: The acupressure pain threshold measured in the left and right BL52 of the subjects was significantly decreased when pressed toward the trunk center (p < .05). In BL52, it was more sensitive to pressure when the direction of pressure is toward the body's center. Conclusions: Acupressure therapy of acupoint is more sensitive to external stimuli than the surrounding. In this study, acupressure directed toward the trunk center is more efficient than toward the belly button in BL52.
