Due to the poor evaluation indexes such as detection accuracy and recall rate when Yolov3 network detects aircraft in remote sensing images, in this paper, we propose a remote sensing image aircraft detection method based on machine vision. In order to improve the target detection effect, the Inception module was introduced into the Yolov3 network structure, and then the data set was cluster analyzed using the k-means algorithm. In order to obtain the best aircraft detection model, on the basis of our proposed method, we adjusted the network parameters in the pre-training model and improved the resolution of the input image. Finally, our method adopted multi-scale training model. In this paper, we used remote sensing aircraft dataset of RSOD-Dataset to do experiments, and finally proved that our method improved some evaluation indicators. The experiment of this paper proves that our method also has good detection and recognition ability in other ground objects.

Managers, supervisors, executives and others whose office is to get work done by staff in organizations would desire a motivated workforce. Despite the advances in technology, any system has tot have motivated people to achieve its goals and at some time or other, no one in charge of a unit has failed to wonder, 'How best do I get individuals and groups motivated'? What is motivation, how can employees be motivated to direct their energies towards execution of the job and how is this achieved on a sustained on-going basis? Is a highly motivated employee necessarily an ace performer? These are the issues which the author would address in the present paper. The authors has conducted an empirical study by administering motivational test and collected data from 100 corporate of Bhopal region.

During a survey of fungal diversity in Korea, two fungal strains, KNU17-1 and KNU17-199, were isolated from paddy field soil in Yangpyeong and Sancheong, respectively, in Korea. These fungal isolates were analyzed based on their morphological characteristics and the molecular phylogenetic analysis of the internal transcribed spacer (ITS) rDNA sequences. On the basis of their morphology and phylogeny, KNU17-1 and KNU17-199 isolates were identified as Albifimbria verrucaria and Deconica coprophila, respectively. To the best of our knowledge, A. verrucaria and D. coprophila have not yet been reported in Korea. Thus, this is the first report of these species in Korea.

Due to change in management environment and paradigms, companies need to the open management system that provides information for real-time costing, customer satisfaction, decision making support, responsibility management etc. We are not ready to implement this system yet. But we must introduce a new management system, i.e., ABMS(Activity- Based Management System) on the basis of the ARC(Activity-Based Costing) by development of production/information technique. This paper realizes foundational concepts of Activity and ABC, reestablishes the concept of ABC correctly and expands ABC for ABMS. Thus this paper is useful for ABMS modeling, leading competitors, total productivity improvement and strategic management for the best quality and service.

Cybersecurity has been vital for decades and will remain vital with upcoming ages with new technological developments. Every new day brings advancement in technology, which leads to new horizons, and at the same time, it brings new security challenges. Numerous researchers around the globe are continuously striving hard to provide better solutions for the daily basis of new arising security issues. However, the challenges are always there. These challenges become new norms during the current Covid pandemic, where most industries, small industrial enterprises, education, finance, public sectors, etc. were under several attacks and threats globally. The hacker has more opportunities during the pandemic period by shifting most of the operations live. This research enlightened the several cybersecurity attacks and threats during this pandemic time globally. It provided the best possible recommendations to avoid them using the cyber awareness and with appropriately linked training. This research can provide a guideline to the above stated sector by identifying the related attacks.

This article is concentrated on the organization for labor exchange in producing hemp cloth at Geumso-ri, Imha-myoun, Andong city. The organization is called "Sam-dool-ge", and it is different from the organization for labor exchange in producing rice because it is managed by women mostly. ln harvesting hemp, same amount of labor and expenses are invested. Especially, labor is supplied in equal condition. In spinning hemp cloth, the work is shared on the basis of same tech level. In threading the warp and fastening hemp cloth. the work conducted collaborately under the best engineer's direction. "Sam-dool-ge", a gil-sam labor exchange, also presents cultural creativity which produces and inherits the folkloric tradition, and also has the quality as a rite of passage. Nowadays, producing hem cloth is for pursuiting of profits than for making clothes as it used to be. This tradition will be lasted at least for a while because some young generations are beginning to participate in and old generation is teaching them good.

This paper presents an optimum hybrid SVPWM technique for three-level voltage source inverters (VSIs). The proposed hybrid SVPWM technique aims to minimize total harmonic distortion (THD). A new parameter is introduced to incorporate the heterogeneous nature of switching sequences of SVPWM technique. The proposed hybrid SVPWM technique is implemented on a low-cost PIC microcontroller (PIC18F452) and verified experimentally with a 2 KVA three-phase three-level insulated gate bipolar transistor-based VSI. Optimum switching sequence results in the three-level inverter configuration are demonstrated. The proposed hybrid SVPWM technique improves the THD performance by 17.3% compared with the best available three-level SVPWM technique.

The Cu/Cu2O/CuO photoelectrode has been successfully fabricated by Rapid Thermal Annealing technique. The structural characterization of fabricated photoelectrode was performed using X-Ray diffraction, while elemental composition of the prepared material has been checked with X-Ray Photoelectron Spectroscopy. The synthesis parameters are optimized on the basis of photoelectrochemical performance. The best photoelectrochemical performance has been observed for the Cu/Cu2O/CuO photoelectrode fabricated at 550 ℃ oxidation temperature and oxidation time of 50 seconds with highest photocurrent density of -3 mA/㎠ at -0.13 V vs. RHE.

Although it has been confirmed that excessive body fat increases health risks and all-cause mortality, several epidemiological studies have reported that overweight or obesity in patients with chronic diseases and in older adults is advantageous with respect to mortality. Several mechanisms have been proposed to explain the biological basis of this obesity paradox. The marked heterogeneity of findings observed across studies and the possibility of systematic errors in these studies have cast doubt on the actual existence of the obesity paradox. However, the obesity paradox questioned the validity of body mass index as the best indicator for obesity in terms of predicting its comorbidities and urges clinicians to focus more on changes in body composition and related metabolic derangements, rather than body weight per se.

Ten compounds, consisting of neoflavonoids (1-5), isoflavonoids (6 and 7), flavanone (8), and chalcones (9 and 10) were isolated from the ethyl acetate and n-butanol-soluble fractions of the heartwood of Dalbergia melanoxylon. The chemical structures were identified on the basis of spectroscopic evidence and compared to previously reported spectra. Compounds 1-10 were evaluated for cytotoxicity against HCT116 human colorectal cancer, MDA-MB-231 human metastatic breast cancer, and A2058 human melanoma cell lines. Among them, compounds 3 and 10 showed the strongest cytotoxic activity with IC₅₀ values of 11.92±1.07 μM, 10.83±1.02 μM, and 14.37±1.02 μM, 13.62±1.09 μM against HCT116 and MDA-MB-231 cell lines, respectively. Compounds 9 and 10 also had cytotoxic activity with IC₅₀ values of 13.49±1.18 μM and 9.82±0.91 μM against A2058 cell lines, respectively. To the best our knowledge, compounds 2 and 5-10 were isolated from this source for the first time.
