With an ageing society comes the increased prevalence of gait disorders. The restriction of mobility leads to a considerable reduction in the quality of life, because associated falls increase morbidity and mortality. Consideration of gait analysis data often alters surgical recommendations. For that reason, the early and systematic diagnostic treatment of gait disorders can spare a lot of suffering. As modern gait analysis systems are, in most cases, still very costly, many patients are not privileged enough to have access to comparable therapies. Low-cost systems such as inertial measurement units (IMUs) still pose major challenges, but offer possibilities for automatic real-time motion analysis. In this paper, we present a new approach to reliably detect human gait phases, using IMUs and machine learning methods. This approach should form the foundation of a new medical device to be used for gait analysis. A model is presented combining deep 2D-convolutional and LSTM networks to perform a classification task; it predicts the current gait phase with an accuracy of over 92% on an unseen subject, differentiating between five different phases. In the course of the paper, different approaches to optimize the performance of the model are presented and evaluated.

This study aims at describing the process of word-formation used on messaging applications found in the Play Store. This is descriptive qualitative research. The data are messaging applications written in English and in the form of words. To collect the data, the researchers use observation. The analysis data consists of three steps namely data reduction, data display, and verification. There are 56 data found. There are 6 types of word formations; Affixation (4 data), compounding (15 data), blending (4 data), coinage (8 data), clipping (4 data), reduplication (1 data). However, there are 20 messaging applications that cannot be classified into the type of word formation such as Path, Line, Lemon, etc. They are simple words that have already existed in English and have been used in everyday communication. Meanwhile, nowadays they are used as a name of messaging applications and have different meanings as the real meaning. The suffixes used in the affixation process are –er, -ous, -ster. There are 6 formations of compounding used in the messaging application such as N+N, V+V, N+V, V+N, Adv. + Prep. There are 3 ways of blending process such as taking the whole part of the first word and taking the first syllable of the second, taking the first syllable of the first word and taking the whole part of the second word, taking two syllables from the front part of the first word and taking the last syllable of the second word. Coinage consists of the name of the company and the name of the product. There are two types of clipping found namely fore-clipping and back-clipping. Reduplication happens when there is a copying of the partial part of the word. Apparently, there are morphological processes used in life such as word formation to name the messaging application.

ABSTRAKTujuan penelitian ini adalah untuk mengetahui dan mendeskripsikan: 1) Modelpembinaan anak jalanan di Pondok Pesantren, 2) Kendala-kendala yang terjadi dalam pembinaan anak jalanan, 3) Mengatasi kendala yang ada. Penelitian ini menggunakan pendekatan penelitian kualitatif dengan jenis penelitian deskriptif. Teknik pengumpulan data meliputi: observasi, wawancara, dan dokumentasi. Adapun metode analisis datanya melalui: pengumpulan data, reduksi data, penyajian data, dan penarikan kesimpulan. Hasil dari penelitian menjelaskan bahwa: 1) Pembinaan yang dilakukan di Pondok Pesantren Salafiyah Sabilul Hikmah ini adalah pendekatan secara personal sosial dimana pengurus pondok pesantren harus berinteraksi sosial secara anak per anak agar tahu apa yang sebenarnya diinginkan oleh masing-masing anak serta pembinaan dengan pendekatan secara agama (religius), 2) Kendala yang paling menonjol adalah sulitnya masa peralihan anak-anak yang semula hidup bebas dijalanan dan kemudian hidup di lingkungan pondok pesantren serta kurangnya dana operasional untuk mencukupi kebutuhan sehari-hari para santri, 3) Mengatasi anak yang susah diatur adalah dengan membuat anak - anak tersebeut merasa nyaman maka itulah guna dari pembinaan melalui pendekatan personal sosial,sedangkan kendala dari keuangan adalah bagaimana pendiri Pondok Pesantren menggunakan uang pribadi dalam mencukupi kebutuhan sehari-hari para santri.Kata Kunci : Model Pembinaan, Anak Jalanan, Personal sosial dan religi.ABSTRACTThe research objective is to understand and describe: 1) The mentoring model for street children at Islamic Boarding School, 2) The problems in mentoring for street children, and 3) The solution for solving the problems. This research applied the descriptive qualitative research. The techniques for data collection were observation, interview, and documentation. The analysis data started from data collection, data reduction, result of research and conclusion. The result of this research showed that: 1) The mentoring which was done by Salafiyah Sabilul Hikmah Islamic Boarding School was a personal and social approach where Islamic boarding school staffs should make an social interaction to eachof street children so they could understand their real needs, 2) the most problem which faced by street children was the difficulties on their adaptation from the life street to Islamic boarding school which did not have a good financial to support all their daily needs, and 3) To mentor the street childern who could not be taught easily was by making them feelmore comfortable so it aligned with the goal of a personal and social approach, and to cover the lack of financial on the student’s daily needs was by using the staff’s personal money.Keywords: Mentoring Model, Street Children, Personal and social approach, and religion.

Backward walking (BW) is being increasingly used in neurologic and orthopedic rehabilitation as well as in sports to promote balance control as it provides a unique challenge to the sensorimotor control system. The identification of initial foot contact (IC) and terminal foot contact (TC) events is crucial for gait analysis. Data of optical motion capture (OMC) kinematics and inertial motion units (IMUs) are commonly used to detect gait events during forward walking (FW). However, the agreement between such methods during BW has not been investigated. In this study, the OMC kinematics and inertial data of 10 healthy young adults were recorded during BW and FW on a treadmill at different speeds. Gait events were measured using both kinematics and inertial data and then evaluated for agreement. Excellent reliability (Interclass Correlation > 0.9) was achieved for the identification of both IC and TC. The absolute differences between methods during BW were 18.5 ± 18.3 and 20.4 ± 15.2 ms for IC and TC, respectively, compared to 9.1 ± 9.6 and 10.0 ± 14.9 for IC and TC, respectively, during FW. The high levels of agreement between methods indicate that both may be used for some applications of BW gait analysis.

This study aims to describe ethnomatematics of buying and selling transactions conducted by traders in the traditional market of Kaimana district. It is descriptive researches method with a qualitative approach that emphasizes process analysis. The research subject was one person. The research instrument was in the form of guidelines for observation, interviews, and field notes, which were used to find out how the subjects performed mental calculations. The techniques of analysis data are data reduction, data presentation, and conclusion. Based on the results of the study, it can be concluded that there ethnomatematics activity are show by counting activities in buying and selling transactions. For example, calculate the amount of goods purchased by the buyer, determine the amount of change from the buyer, and calculate the profit of the selling price of each item purchased
