        Estrogen receptor 2 (ESR2) is involved in oestrogen-related apoptosis in cell cycle spermatogenesis but their effects have not yet confirmed in pig. Therefore, this study was performed to investigatetheir association with semen motility and kinematic characteristics. DNA samples from 126 Duroc pigs with records of sperm motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity(VCL), Straight-line velocity(VSL), the ratio between VSL and VCL(LIN), Amplitude of Lateral Head displacement(ALH)] were used in present study. A single nucleotide polymorphism (g.35547A>G) was associated with MOT, VCL, VAP and ALH in Duroc population (p < 0.05). Therefore, we suggest that the porcine ESR2 may be used as a molecular marker for Duroc boar semen quality, although its functional effect was not clear yet. These results will improve the understanding of the functions of the ESR2 in spermatogenesis within the reproductive tracts, and will shed light on ESR2 as a candidate gene in the selection of good sperm quality boars.

        The present study aimed to investigate the effects of kinematic taping therapy on menstrual distress, pain, and prostaglandinF2α. The experimental subject was a 24 years old woman with the pain of over 5 points on the dysmenorrhea measurement test and no unusual reactions on the taping test. The menstrual distress was measured by the Menstrual Distress Questionnaire (MDQ), and the dysmenorrhea was measured by the Visual Analogue Scale (VAS) before and after the intervention. The prostaglandin F2α(PGF2α) was measured on the first day of menstruation before the intervention and 24 hours after the taping therapy by the blood test. The intervention of kinematic taping was conducted by the instructor of the International Kinematic Taping Academy, and the taping was applied to the lower abdomen and the waist. According to the difference of menstrual distress before and after the intervention, the menstrual distress turned out to be decreased to 96 points after the intervention from the 115 points before the intervention. The dysmenorrhea also reduced 3 points on the VAS from 7 points to 4 points before and after the intervention. The PGF2α decreased from 26pg/㎖ to 20pg/㎖ before and after the intervention. Besides, the PGF2α decreased from 26pg/㎖ to 20pg/㎖ before and after the intervention. Results suggest that kinematic taping therapy could be useful to reduce the menstrual distress, pain, and PGF2α.

        The purpose of this study was to identify the immediate effects of Maitland joint mobilization with kinematic taping in subacromial impingement syndrome patients. The Maitland joint mobilization was applied glenohumeral joint. The mobilization was performed at the end of rage to Grade IV. After that, kinematic tape was attached to shoulder joint (supraspinatis, infraspinatis, and trapezius muscles). The intervention period was four days. The measurement was done five times. The shoulder pain, range of motion (flexion, abduction, and rotation of the shoulder joint), muscle tone and stiffness (upper trapezius and deltoid muscle) were measured. The shoulder pain decreased. The range of motion (ROM) was increased all flexion, abduction, and rotation of the shoulder joint. Muscle tone and stiffness were decreased, especially upper trapezius of those was greatly decreased. The findings of present study suggest that Maitland joint mobilization with kinematic taping is effective in decreasing pain, muscle tone and stiffness, and in increasing shoulder ROM in patients with subacromial impingement syndrome.

        본 논문에서는 곤충 모방 날갯짓 초소형 비행체에 적용될 끈을 이용한 날갯짓 구동 장치의 구동 원리와 그 최적화 과정이 소개된다. 이 날갯짓 구동 장치는 끈을 이용하여 구조의 경량화와 관성력 감소로 인한 에너지 효율 상승을 목적으로 설계되 었다. 먼저 장력만 전달할 수 있는 끈의 특성을 고려하여 운동학적인 수식이 정립되었으며, 이를 통해 구동 장치의 거동 특 성을 파악할 수 있었다. 이 수식들은 수정된 패턴 검색 최적화 과정에 포함되어 메커니즘의 운동학적 최적화를 가능하게 만 들었다. 최적화된 형상으로 제작된 시제품은 설계의 구동 원리에 맞게 운동하였으며, 그 날갯짓 폭은 목표한 날갯짓 폭을 만 족시켰다. 수치적 시뮬레이션과 실험 결과는 잘 일치하여 제시된 구동 장치가 실제로 활용될 수 있음을 보였다.

        The purpose of this study was to examine the effect of kinematic taping on respiratory muscle strength in smokers. Twenty - five university students who smoke were involved in the study. All participants were applied to kinematic taping to breathe deeply again. Subjects sit on their backs straight up and place their hands on their thighs. Tape 1 is applied from the lower prominent neck vertebrae(seven cervical vertebra) inward and downward, past shoulder blade, around ribs to the lower tip of sternum. Tape 2 extends to the lower, outer edge of shoulder blade, around ribs to the lower tip of sternum. Respiratory muscle strength was measured with Micro Mouth Pressure Measurement before and after taping. The application of kinematic taping significantly improved the inspiratory and expiratory muscle strength (p<.05). These findings suggest that kinematic taping effective in improving respiratory muscle strength and deep breathing.

        For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Phospholipase C zeta (PLCz) is important enzyme in spermatogenesis, but their effect has not been confirmed in pigs yet. Therefore, this study was aimed to analyze their association with sperm motility and kinematic characteristics. DNA samples from 124 Duroc pigs with records of sperm motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity (VCL), Straight-line velocity (VSL), the ratio between VSL and VCL (LIN), Amplitude of Lateral Head displacement (ALH)] were subjected. A SNP in non-coding region of PLCz g.158 A > C was associated with MOT (p < 0.05), VCL (p < 0.01), LIN (p < 0.01) and ALH (p < 0.05) in Duroc population. Therefore, we suggest that the intron region of the porcine PLCz gene may be used as a molecular marker for Duroc boar semen quality, although its functional effect was not defined yet. Whether the association is due to the candidate gene or not require further verification. Thus, it will be of interest to continue association studies in the regions surrounding those genes.

These results might shed new light on the roles of ESR2 in spermatogenesis as candidate gene for boar fertility, but still the lack of association across populations should be considered.

        Cluster-of-differentiation antigen 9 (CD9) gene expressed in the male germ line stem cells is crucial for sperm–egg fusion, and was therefore selected as candidate gene for boar semen motility and kinematic characteristics. This study was performed to investigatetheir association with semen motility and kinematic characteristics. DNA samples from 96 Duroc pigs with records of sperm motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity(VCL), Straight-line velocity(VSL), the ratio between VSL and VCL(LIN), Amplitude of Lateral Head displacement(ALH)] were used in present study. A single nucleotide polymorphism (g.358A>T) in intron 6 was associated with MOT, VCL, VAP and ALH in Duroc population (p < 0.05). Therefore, we suggest that the porcine CD9 may be used as a molecular marker for Duroc boar semen quality, although its functional effect was not clear yet. These results will improve the understanding of the functions of the CD9 in spermatogenesis within the reproductive tracts, and will shed light on CD9 as a candidate gene in the selection of good sperm quality boars.
