At present, defogging technologies can be roughly divided into two categories: the first category is the method of defogging based on image enhancement non-physical model. This method does not start from the essence of optical imaging, but only improves the visual effect of the image by improving the contrast and color of the image, so as to achieve the purpose of defogging. The commonly used methods include histogram equalization, contrast enhancement and automatic color levels, Retinex theory and wavelet transform, etc. The second type is based on atmospheric scattering physical model. This method analyzes the degradation mechanism in the process of imaging, establishes the degradation model of foggy image, and restores the real scene without fog by using the prior knowledge in the degradation process. This method needs to obtain prior conditions as model parameters, but the prior conditions are often difficult to obtain. In this paper, an adaptive power image defogging algorithm based on multi-scale Retinex and modified dark channel is proposed. Sobel operator is used to detect the edges of luminance components and multi-scale Retinex algorithm is used to eliminate luminance components. A priori theory of dark channel optimization by guided filtering is used to obtain rough estimated transmittance. The global atmospheric light value is selected by quadtree subspace search method. In order to eliminate the phenomenon that the restored image is dark as a whole and cannot display details, the brightness value is corrected by two-dimensional gamma function, and finally the restored defogging image is obtained. The experimental results show that the proposed algorithm can effectively restore the details of foggy images, completely remove foggy images, have good color brightness, and the images are clear and natural.

The application of building extraction involves a wide range of fields, including urban planning, land use analysis and change detection. It is difficult to determine whether each pixel is a building or not because of the large difference within the building category. Therefore, automatic building extraction from aerial images is still a challenging research topic. Although deep convolutional networks have many advantages, the networks used for image-level classification cannot be directly used for pixel-level building extraction tasks. This is caused by successive steps larger than one in the pooling or convolution layer. These operations will reduce the spatial resolution of feature maps. Therefore, the spatial resolution of the output feature map is no longer consistent with that of the input, which cannot meet the task requirements of pixel- level building extraction. In this paper, we propose a encoder-decoder structure based on conditional random field for building extraction in remote sensing images. The problem of boundary information lost by unitary potential energy in traditional conditional random field is solved through multi-scale building information. It also preserves the local structure information. The network consists of two parts: encoder sub-network and decoder sub-network. The encoder sub-network compresses the spatial resolution of the input image to complete the feature extraction. The decoder sub-network improves the spatial resolution from features and completes building extraction. Experimental results show that the proposed framework is superior to other comparison methods in terms of the accuracy on open data sets, and can extract building information in complex scenes well.

INTRODUCTION: Image forgery detection is a very challenging task now a day. Latest tools and applications make it easy. Artefact change our thought and perceptions.

OBJECTIVES: A forgery detection system is a need of time to detect image forgery.

METHODS: We proposed a blind image forgery detection technique. Optimal threshold-based Enhanced Local Ternary Pattern (OELTP) technique implemented on smoothed image. Features are extracted in the form of frequency to implement Discrete Wavelet Transform (DWT) on the chrominance component of the image. Support Vector Machine is used for classification.

RESULTS: The accuracy of the forgery detection on the proposed technique is better than some of the previous states of work.

CONCLUSION: Image forgery detection system performance has been improved by better localization of the forgery. Performance of the global threshold improved by using the latest technique, and reducing the operational complexity.

Introduction: Telehealth usage increased especially in the coronavirus pandemic.

Objective: To determine whether oral and maxillofacial surgeons (OMS) believe that telehealth is an adequate substitute for in-person consultations.

Methods: OMS were interviewed. These were transcribed and themes and subthemes coded. Quotes were selected to create narratives about themes and subthemes and a frequency table generated.

Results: 20 OMS were interviewed. There were 200 positive, 215 negative, 9 neutral and 256 unstated comments. Major themes were diagnosis, accessibility, patient-centred care, technology and finances. 34 sub-themes were identified. OMS were most satisfied with accessibility and most dissatisfied with diagnosis.

Conclusion: OMS had mixed opinions regarding telehealth. While it can improve access, the technology, interventional capacity and diagnostic ability are limited. Face-to-face was preferred. Further studies are required to improve telehealth.

This study aims to answer the problem of why Java experienced such a long pause from a series of warfare until 1757. At the same time, there was prosperity in Java, which was marked by the rapid increase in agricultural production in the colonial era by the Dutch Company. The subject matter was the keris Pangeran Jimat from the era of the Demak kingdom in 1626, as well as Keris Mintaraga and Keris Rapalan. This keris was made to accompany the manufacture of the giant cannon called Ki Jimat which was used to attack the Portuguese occupation in Malacca. The historical method is used to solve this problem, especially in the prohibition of importing iron into Java. Meanwhile iron is the main ingredient in keris making. This import ban sparked the awareness of Susuhunan Pakubuwana III to stop the war that had killed so many Moslems. The stopping of the war by Company and the Mataram kingdom was based on the fact that all soldiers were warriors whose lives were very valuable. In 1757 the war ceased for a long period of time and Java achieved temporary prosperity.

This study examined Cembengan as an implementation of the Nebu sauyun concept in the tradition of giling tebu (milling sugarcane) at the Tasikmadu Sugar Factory (PG), Karanganyar, Central Java. The concept of Nebu sauyun can be found in Cembengan. This concept is the result of the thought of Prince Sambernyawa (Mangkunegara I). His thought is based on the principle of harmony as his efforts to uphold the existence of Pura Mangkunegaran. On the other hand, Mangkunegara IV as the successor to power also applies the principle of harmony, one of which is through the economic development field in the context of realizing the people welfare. The problem found was how the principles of harmony can be implemented internally and externally through Cembengan. This problem was examined through literature study using a cultural studies approach. The data obtained were processed through historical analysis. The results of this study found that Cembengan is a form of assimilation of the grave pilgrimage culture between Chinese and Javanese. In its development, this tradition extends to the preservation of temanten tebu rituals and traditional arts.

This study will reveal the symbolic meaning of Morga Siwe wedding, Kayu Agung, South Sumatra. This study is very interesting to do because the traditional ritual has many stages. Every stage that appears is laden with noble values of Kayu Agung people. In addition, this study is interesting because the researcher has not found any writings discussing about Morga Siwe wedding. The purpose of this study is to find and describe the noble values represented in every stage of Morga Siwe marriage. This study is an explanation that discusses Morga Siwe wedding ceremony, both the meaning of words, language, and the meaning of symbols, and thus comes to an interpretation of the meaning in the proceedings. The results of the interpretation are related to the lifestyle, habits, and culture of Kayu Agung people so that it gives an educational effect, especially moral education based on the noble values of Kayu Agung people. The method used in this study is the mythological theory of Roland Barthes. Data about Morga Siwe is obtained by using literature and observation methods.

This study aims to describe the implementation of Multiliteracies Pedagogy-based instructional on teaching Public Speaking to enhance The Students’ Higher Order Thinking Skills (HOTS). It is descriptive qualitative research with observation and questionnaire data collection techniques. The research instruments are field notes and the questions of the questionnaire sheet. There are ten questions about the instructional process in it. The subjects of the research are the lecturer of Public Speaking and the twenty students of the English Language Education of Nahdlatul Ulama University of Sidoarjo (UNUSIDA) in the third semester. Then, at the end of the activities, the students write his opinion about the learning process in the questionnaire. The observation shows that the lecturer has applied the four syntaxes of the multiliteracies pedagogy completely in the classroom. The lecturer, automatically, has enhanced the students’ thinking skills by following the syntax of the multiliteracy pedagogy model. The students’ opinion about the teaching-learning process is good with an average of 96,5% of their responses to the questionnaire stated positively. It is suggestive to the next researchers may do any experimental research about the effectiveness of the model for enhancing the students’ higher order thinking skills in Elementary or High Schools.

Narratives, fairy tales, and other forms of storytelling have been long used as one of the means to educate children about good and bad values accepted in the society. Javanese society was no exception. However, the big question is how these values are presented and taught to children. This study aims to explore various virtues and values, good and bad, taught through narrative story telling for children in Java. The stories are collected from the weekly magazine Djaka Lodang, and only stories with human as the actors and with human interaction are chosen. Data collected are in the forms of lexicon, that have meaning as good or bad virtues, such as jujur ‘honest’, rukun ‘harmonious’, andhap asor ‘humble’, bekti ‘devoted’, ngajeni ‘appreciate (others)’, ugungan ‘selfish’, tukaran ‘dispute (with other)’ by regarding the sentence’s context so the function of introducing these virtues could be seen clearly. A virtue can have positive meaning if there is another virtue as a comparison in its polarity, for example ‘honest’ is a good virtue, because its opposite ‘lie’ exists as the bad virtue. Introducing virtues of both polarities are done with the same goal, that is to avoid conflict with other people within the society. This actually corresponds with the main concept of socializing in Javanese society, achieving a harmonious society.

Literary works have been present on this earth since time immemorial. This is the same for the Buginese people in South Sulawesi. Literary works in South Sulawesi are not only in the form of prose but are also found in the form of poetry. Poetry in Bugis society is called Elong. Elong as a reflection of Bugis society, of course, is full of and in line with the existing culture of the Bugis community. Thus, Elong is inseparable from traditions, conventions, beliefs, mindsets and even ideology. Therefore, literary works are of course full of values and meanings. One of the old poetry forms in Bugis society is elong. Etymogically, elong is defined as singing. Because elong is found in the Bugis community or in the Bugis to ugi, it is then shortened to elong ugi or elompugi. One of the elompugi that was found was elompugi assimellereng, namely elong which tells about the relationship between human beings. The research design used was descriptive qualitative. Data collection was carried out through field research and archival research, especially from the lontara manuscript archives. The research results obtained found that elong assimillereng is a poem that talks about the expression of affection for the opposite sex. This expression can mean feelings of love, anger and annoyance. Regardless the expression of feelings of love and anger because of rejection, there are actually educational values behind it.
