Meanwhile, the SRI model needs to be developed to see the business sustainability through implementation knowledge management system in the organization. The data collection method was carried out, starting with building a research instrument based on knowledge management theory and continued with observation and distributing questionnaires to respondents who were involved in the business process of managing SRI. The data analysis method was used to process the data from the questionnaire, factor analysis method was used and the method to build the model used was the regression analysis method. The results obtained from this study are the discovery of 4 (four) factors with a number of indicators that are grouped on each formed factor, which can then be made and built a readiness model that reflects current conditions, so that it can be used to build predictions in the future related to readiness. implementation of knowledge management system development in order to support increased understanding of the service recovery index in the organization.","PeriodicalId":278114,"journal":{"name":"Proceedings of the 2021 9th International Conference on Information Technology: IoT and Smart City","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129042030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The different values of different communities are expressed by the difference of trust thresholds inside and outside communities. The simulation results show that information cocoon exist and have deep and shallow levels; Increasing the tolerance of communication with heterogeneous communities has a positive effect on restraining cocoon; To establish a mechanism to increase the connection between heterogeneous communities is helpful to inhibit the occurrence of cocoon phenomenon; The opinion tends to be close to the mainstream opinion in the final state, and targeted “cocoon-breaking” measures have been proposed.","PeriodicalId":278114,"journal":{"name":"Proceedings of the 2021 9th International Conference on Information Technology: IoT and Smart City","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117260267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A large number of tumor patients need to receive radiotherapy every year. However, radiation not only kills tumor cells but also causes damage to normal tissues during the treatment. To control the additional damage and ensure the treatment effect, it is necessary to verify and calibrate the absorbed dose of the patient. This paper proposes a new 3D dose reconstruction method based on EPID data, which can verify the radiation dose more accurately and quickly.Our method uses the idea of projection reconstruction and directly deduces the corresponding dose distribution from EPID data and CT images of the phantom. Experiments show that the method in this paper has short calculation time, good reconstruction accuracy, and high practicability.","PeriodicalId":278114,"journal":{"name":"Proceedings of the 2021 9th International Conference on Information Technology: IoT and Smart City","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132481614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system takes a sensor node as input device and a 2D dentition as output interface. Specifically, the sensor node can be attached onto the handle of a toothbrush to get the 3D Euler angles, which are used as the features for training Random Forester Classifier (RFC) Model. Moreover, the predicted brushing region will be displayed on the dentition interface in real-time. All teeth are divided into 16 regions to evaluate the detection accuracy. User-dependent offline experiment shows that the RFC-based automatic threshold definition method achieves 97.6% validation accuracy, which is about 35% higher than the manual threshold definition method.

The LSTM is applied as the decoder to generate the fluent fine-grained descriptions for human actions. To focus on the most relevant part of actions and capture the correlation between actions and descriptions, an attention mechanism is applied in the proposed method.

From the perspective of drivers, the use intention of drivers when the shared parking cost changes is obtained through RP and SP surveys, a multiple logit model is constructed to predict the probability of drivers choosing the shared parking scheme under different parking cost levels, and calculate the times and change rate of drivers using shared parking under each parking cost level. The research shows that the decrease of parking cost has a positive impact on the use times of shared parking, while the increase of parking cost has a negative impact on the use times of shared parking. High parking cost will inhibit the development of shared parking; At the same time, the sensitivity of shared parking use times to the increase and decrease of parking cost is different. When the parking cost increases by 80%, the use times is only 3.499 times / month, and the utilization rate decreases by 76.21%; When the parking fee was reduced by 80%, the number of times of use was 19.83 times / month, and the utilization rate increased by 34.85%.

However, teaching and learning methods could be changed for developing Information and Communication Technology (ICT). It's time to adapt students with interactive learning system so that they can improve their learning, catching, and memorizing capabilities. We developed an educational resource material (animated film in Tahderiyyah Literacy App) for students of pre-school level using different Muslim practices content. The objective of this paper is to examine the impact of student's abilities to acquire new knowledge or skills through educational resource materials and blended learning that is integration of material with teacher's instructions. We visited a primary school in Manila City, Philippines for this study and conducted evaluation in different sessions with the same groups of students (i) the first session was with only educational resource material and assessment was done with 10 questionnaires, (ii) the second session was with the animated film combined with teacher's instructions and assessed with the same questionnaires. This integration of animated film with verbal instructions is a blended approach of learning. The approach greatly promoted student's ability of acquisition of knowledge and skills. Students response and perception were very positive towards the blended technique than the other methods. This resource may be appropriate method to be part of blending leaning system especially for school children.","PeriodicalId":278114,"journal":{"name":"Proceedings of the 2021 9th International Conference on Information Technology: IoT and Smart City","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122470672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
