Recent healthcare environments have characteristics of expanding the scope of healthcare-impacting healthcare, complexity resulting from diversification of components, and accelerating the pace of change. Drugs are used for the prevention, mitigation, and treatment of diseases, so they can inevitably cause harm, while they have efficacy and effectiveness, which are key elements of health recovery. Therefore, many countries regulate permits for safe and effective medicines, and also designate essential drugs directly related to life as pay targets and guarantee health insurance. Especially Pharmacist relying on manpower for composition medicine is liable for mal-manufacture due to combination of toxic medical substances or other chemical usage. In this paper, we focus on using Kiosk and Optical Character Recognition (OCR) for automated pharmacy to level up medical service and create labor friendly environment for pharmacist themselves through maintenance of prescription data and automated manufacturing solution. Presentation of drug substances and precautions will lead to efficient drug prescription and prevent misuse of information while auto manufacturing system efficiently maintain labor force and raise patient satisfaction level by reduction of waiting time.

This study attempted to confirm the factors that the meaning of work perceived by organization members and job embeddedness affects creative behavior. In addition, we tried to confirm the relationship between the meaning of work and job embeddedness. On the other hand, we tried to verify the mediating effect of job embeddedness between the meaning of work and creative behavior. Accordingly, the following results and implications were derived through the hypotheses set for the members of small and medium-sized enterprises. First, the meaning of work showed a positive effect on job embeddedness and creative behavior, and it was empirically analyzed that job embeddedness was improved on creative behavior. In order to improve the creative behavior of organizational members, the need for advancement of the management and training system to systematically improve and strengthen the meaning of work and job embeddedness has emerged. Second, job embeddedness showed a mediating effect between the meaning of work and creative behavior. In other words, the employee's job embeddedness acted as a direct or indirect factor according to the improvement of the meaning of work and creative behavior. Accordingly, as one of the major factors in human resource management and strategic human resource development for the advancement of the sustainable management system, the need for institutional establishment and implementation was required as it became more efficient and effective.

We have studied the speed regulation of the permanent magnet synchronous motor (PMSM) servo system in this paper. To optimize the PMSM servo system's speed-control performance with disturbances, a non-linear speed-control technique using a back-propagation neural network (BP-NN) algorithm for the controller design of the PMSM speed loop is introduced. To solve the slow convergence speed and easy to fall into the local minimum problem of BP-NN, we develope an improved BP-NN control algorithm by limiting the range of neural network outputs of the proportional coefficient Kp, integral coefficient Ki of the controller, and add adaptive gain factor β, that is the internal gain correction ratio. Compared with the conventional PI control method, our improved BP-NN control algorithm makes the settling time faster without static error, overshoot or oscillation. Simulation comparisons have been made for our improved BP-NN control method and the conventional PI control method to verify the proposed method's effectiveness.

Today people adopt various contents from their mobile devices which lead to numerous platforms. As technology of 5G, IOT, and smart phone develops, the number of people who create, edit, collect, and share their own videos, photos, and articles continues to increase. As more contents are shared online, the numbers of data being stolen continue to increase too. To prevent these cases, an authentication method is needed to encrypt the content and prove it as its own content. In the report, we propose a few methods to secure various misused content with secondary security. A unique private key is designed when people create new contents through sending photos or videos to platforms. The primary security is to encrypt the “Private Key” with a public key algorithm, making its data-specific “Timeset” that doesn’t allow third-party users to enter. For the secondary security, we propose to use Message Authentication Codes(MACs) to certify that we have produced the content.

The purpose of this study is to analyze the relationship among selection attributes, consumption value brand attitude, fun, brand loyalty and quality of life. The subjects of the empirical study were selected by the Korea Fashion Industry Research Institute using the convention sampling method and the quota sampling method for 241 consumers who have purchased brands classified as "athleisure" within the past year For each variable constructed to verify reliability and validity of the measurement model, reliability tests using Cronbach' alpha were performed using IBM SPSS Win Ver. 23.0. To verify the unidimensionality of the measurements, we conducted a confirmatory factor analysis using AMOS 22.0 and a structural equation model to determine the structural relationship between variables. As a result of the study, First, both intrinsic and extrinsic attributes, which are sub-factors of selection attributes, have been shown to have a significant effect on consumption value. Second, consumption value has been shown to have a significant impact on brand attitude and fun. Third, brand attitudes have been shown to have a significant impact on brand loyalty. Finally, fun has been shown to have a significant impact on quality of life.

This paper proposes a low power radio frequency receiver front-end where, in a single stage, singlebalanced mixer and voltage-controlled oscillator are stacked on top of low noise amplifier and re-use the dc current to reduce the power consumption. In the proposed topology, the voltage-controlled oscillator itself plays the dual role of oscillator and mixer by exploiting a series inductor-capacitor network. Using a 65 nm complementary metal oxide semiconductor technology, the proposed radio frequency front-end is designed and simulated. Oscillating at around 2.4 GHz frequency band, the voltage-controlled oscillator of the proposed radio frequency front-end achieves the phase noise of ‒72 dBc/Hz, ‒93 dBc/Hz, and ‒113 dBc/Hz at 10KHz, 100KHz, and 1 MHz offset frequency, respectively. The simulated voltage conversion gain is about 25 dB. The double-side band noise figure is ‒14.2 dB, ‒8.8 dB, and ‒7.3 dB at 100 KHz, 1 MHz and 10 MHz offset. The radio frequency front-end consumes only 96 μW dc power from a 1-V supply.

We compare Over-the-Tops (OTTs), Netflix and Amazon Prime Video (APV) with five success factors of innovation. Firstly, Netflix offers better personalized service than APV, because APV has collaborative filtering algorithms to recommend safe bets, not the customers really want. Secondly, APV’ user interface is undercooked to lock the members in, even if it has more content and better price offer than Netflix retaining its loyal customers despite the price increase. Thirdly, Netflix has simple subscription model with three tiering, but APV has complicated pricing model having annual and monthly, APV and Prime Video (AV) app, Amazon subscription and extra payment of Amazon Prime Channels (APCs). Fourthly, Amazon has fewer partnership than Netflix especially when it comes to local TV series. Instead, Amazon has live TV channel collaboration including sports content. Lastly, both have strategic and operational agility in their organization well.
我们将ott (Over-the-Tops, ott)、Netflix和亚马逊Prime Video (Amazon Prime Video, APV)与五大创新成功因素进行了比较。首先，Netflix提供了比APV更好的个性化服务，因为APV有协同过滤算法来推荐安全的投注，而不是客户真正想要的投注。其次，APV的用户界面不够成熟，无法锁定用户，即使它拥有比Netflix更多的内容和更优惠的价格，但在价格上涨的情况下仍能留住忠实用户。第三，Netflix有简单的三层订阅模式，而APV有复杂的定价模式，包括年和月、APV和Prime Video (AV)应用、亚马逊订阅和亚马逊Prime Channels (apc)的额外付费。第四，亚马逊的合作伙伴比Netflix少，尤其是在本地电视剧方面。相反，亚马逊有包括体育内容在内的电视直播频道合作。最后，两者在其组织中都具有良好的战略和操作敏捷性。

The operation of a wastewater treatment plant (WWTP) is a complex task which requires to consider several aspects: adapting to always changing influent composition and volume, ensuring treated effluents quality complies with local regulations, ensuring dissolved oxygen levels in biological reaction tanks are sufficient to avoid anoxic conditions etc. all of it while minimizing usage of chemicals and power consumption. The traditional way of managing WWTPs consists in having employees on the field measure various parameters and make decisions based on their judgment and experience which holds various concerns such as the low frequency of data, errors in measurement and difficulty to analyze historical data to propose optimal solutions. In the case of activated sludge WWTPs, parts of the treatment process can be automated and controlled in order to satisfy various control objectives. The models developed by the International Water Association (IWA) have been extensively used worldwide in order to design and assess the performance of various control strategies. In this work, we propose to review most recent WWTP automation initiatives around the world and identify most currently used control parameters and control architectures. We then suggest a framework to select WWTP model, control parameters and control scheme in order to develop and benchmark control strategies for WWTP automation.
