Purpose: This study aimed to investigate effective cueing methods for selective muscle activation of the serratus anterior. Methods: Based on the inclusion criteria, 26 healthy adults, both males and females, were recruited for the measurement of muscle activation of the upper trapezius and serratus anterior muscles while performing basic movements in knee push-up plus (KPP) and dynamic hug (DH) positions using five different cueing methods. An electromyogram was used to measure muscle activation, and both muscle activation and muscle ratio (serratus anterior/upper trapezius) were compared during the basic movements and different cueing methods. The cueing methods were trapezius verbal cueing, trapezius verbal cueing + trapezius tactile cueing, emphasis verbal cueing, serratus anterior tactile cueing, and trapezius verbal cueing + trapezius tactile cueing + serratus anterior tactile cueing. Results: The results of the study showed that there was a significant difference in the muscles for the two exercises (p < 0.05). There was also a significant difference between the cueing methods (p < 0.05). The correlative effect between the muscles and cueing methods was also significant (p < 0.05). The muscle ratio in trapezius verbal cueing + trapezius tactile cueing + serratus anterior tactile cueing during KPP and DH was higher than in basic movements and other cueing methods. This confirms that trapezius verbal cueing + trapezius tactile cueing + serratus anterior tactile cueing is an effective cueing method for selective activation of the serratus anterior during KPP and DH. This study also demonstrated that cueing by a therapist may both increase and decrease selective muscle activation. Conclusion: Through this study, an effective cueing method to selectively activate the serratus anterior may be suggested, and the results of this study may provide basic information regarding future studies and clinical practice.

This study was conducted to investigate the quality characteristics of Kimchi during fermentation and storage according to containers with native plant extract. The containers used in the experiment were antimicrobial polypropylene containers(KAPP) developed with the addition of native plant extracts, and it was tested by comparing the microbial changes and sensory characteristics of the existing commercial containers, such as polypropylene containers(KPP), stainless steel containers(KST), and porcelain containers(KPC). Change in total microbial cell were similar for each container. Coliform maintained the lowest level from 15 days after storage to 50 days. Leuconostoc spp. and Lactobacillus spp. showed a rapid increase in all four storage containers until the 15th day of storage and then decreased. The KAPP container maintained its highest level. The sensory evaluation was carried out on Kimchi optimal condition(storage 40 days). The sensory scores of KAPP were generally higher than those of other experimental samples in characteristics of appearance, odor, taste and overall preference. As a result, KAPP container has an excellent antibacterial effect as compared with the three commercially available storage containers, is effective for fermentation of lactic acid.

Technical Measures includes Measures of Effectiveness(MOEs), Key Performance Parameters(KPPs), Measures of Performance(MOPs) and/or Technical Performance Measures(TPMs). Technical measurement is the set of measurement activities used to provide supplier and/ or acquirer insight into progress in the definition and development of the technical solution, ongoing assessment of the associated risks and issues. This paper describes how technical measures can be applied, using the measurement process described in the previous study and shows the relationship between the various types of technical measures.

Real-time performance is to return the exact result value to the correct cycle, or to perform the specified work at a certain cycle. Windows does not support real-time performance, so it supports real-time performance using expensive third parties such as RTX and INtime. This paper aims to support real-time performance of Windows through RTiK, a real-time kernel that operates in the form of a device driver in Windows. In Windows 7, RTiK used a timer using local APIC supported by x86 hardware. However, due to the Kernel Patch Protection (KPP) on Windows 10, it became impossible to use a local APIC timer. Therefore, a timer is implemented to inform the determined cycle using Local APIC IPI, and performance measurement is performed to confirm that the cycle operates normally within the error range. This enables real-time performance on Windows 10.

In this report, a specialization plan for wearable robots by mission profile was investigated and analyzed to derive an application plan. The final goal of this study was to derive the operating requirements of wearable robots according to specialized plans, and to conduct a specialized study on wearable robots by mission profile through investigation/analysis of specialized plans for each mission profile. In the study, 1) Research on technology trends related to military wearable robots such as patents and papers, 2) Research/analysis of mission profiles to characterize wearable robots, 3) Analysis of wearable robot specialization plans according to mission profiles, and 4) Requirements for wearable robot operation were derived. In the first time of the study, a survey on technology trends related to wearable robots for soldiers such as patents and papers was completed, and a military consultative body was conducted to derive measures to characterize wearable robots. In addition, a survey was conducted on mission profiles, and the second time study derived Key Performance Parameters (KPP) for operational performance, core performance, and system performance based on scenarios by mission profile. However, it is revealed that the KPP derived from the research results was not covered in this paper because it was judged that more in-depth research was needed prior to disclosure. In order to prepare for future battlefield situations and increase the usability of wearable robots, this study was conducted to characterize wearable robots by considering the characteristics of soldiers' equipment according to mission profiles and to characterize wearable robots by mission profile.

The well-established Universal Powder Press UPP, designed by the Swiss press manufacturer Osterwalder AG in Lyss, went through a major improvement process. The result is a high efficient production machine with state-of-the-art technology. It will be shown the technical design, some process engineering as well as the influence of PRP - =Part-Related-Programming, first published in 1994 - on the set-up time. This development has enabled Osterwalder to round off their range of presses, the mechanical-hydraulic KPP as well as the hydraulic CA-NC II and UPP, to an attractive offer ranging from 120 kN up to 10'000 kN.

The logistics cost in Korea is very higher than that of the other countries. Thus, we propose to the way to reduce company's logistics cost in the paper industry. Each company in the paper industry is having its particular sized pallets and using them to manufactured products, store, deliver, retrieve empty pallet and so on. In this reason, the logistics cost is still increasing. As the common introduction of Pallet Pool System to "Paper Industry", the logistics cost could be reduced up to 24% and 1.8 billion won saved approximately, and it possibly attributes to the increase of company profit and the strength of the company competitiveness.itiveness.
