Green Chemistry, juga dikenal sebagai kimia hijau, adalah suatu pendekatan ilmu kimia yang bertujuan untuk merancang, mengembangkan, dan menerapkan proses kimia dan produk kimia yang ramah lingkungan dan berkelanjutan. Serangkaian prinsip dan aturan yang dikenal sebagai "etika kimia hijau" mengatur bagaimana manusia berperilaku sehari-hari dalam kajian kimia hijau. Kategori ini mencakup topik seperti tanggung jawab sosial, etika pertimbangan, dan bagaimana mereka harus berperilaku saat melakukan segala sesuatu dengan mempertimbangkan prinsip kimia hijau. Kajian kimia hijau ini menjadi salah satu materi kimia di kelas X SMA pada implementasi Kurikulum Merdeka. Kehidupan di asrama atau pondok sering kali melibatkan banyak orang yang tinggal bersama dan berbagi fasilitas. Santri atau siswa menjadi bagian terpenting dalam kehidupan pondok. Sisa makanan santri menjadi hal yang unik untuk dikaji dari sisi etika kimia hijau. Penting untuk digali dan dianalisis etika kimia hijau dari para santri terkait fenomena sisa makanan di kehidupan pondok. Penelitian ini merupakan penelitian deskriptif kualitatif. Partisipan penelitian ini adalah seluruh santri kelas X sebuah MA Mu’allimin Muhammadiyah Yogyakarta yang telah diajarkan materi kimia hijau. Secara acak dari santri kelas X diamati perilakunya dalam hal berkaitan makan siang di asrama. Kajian tentang pandangan santri terhadap nasi dan lauk sisa makan mereka diamati. Dengan bekal pengetahuan akan konsep kimia hijau, sebagian dari santri sudah menerapkan dan sebagian lain masih belum jelas memunculkan perilaku dan sikap dari konsep kimia hijau dalam masalah sisa makanan santri. Beberapa konsep dari kimia hijau merupakan etika untuk memunculkan pembangunan yang berkelanjutan. Santri sudah tahu dan paham akan konsep tersebut, tetapi untuk mengaplikasikannya dalam  kehidupan sehari-hari membutuhkan pembiasaan.

Authors: Rahman Mahmudur , Gao Jifan , Carey Kyle A , Edelson Dana P , Afshar Askar , Garrett John W , Chen Guanhua , Afshar Majid , Churpek Matthew M
Published: October 2024

BACKGROUND

Early detection of clinical deterioration and timely intervention for hospitalized patients can improve patient outcomes. Existing early warning systems rely on variables from structured data, such as vital signs and laboratory values, and do not incorporate other potentially predictive data modalities. Because respiratory failure is a common cause of deterioration, chest radiographs are often acquired in deteriorating patients, which may be informative for predicting their risk of intensive care unit (ICU) transfer.

OBJECTIVE

To compare and validate different computer vision models and data augmentation approaches with chest radiographs for predicting clinical deterioration.

METHODS

This retrospective observational study included adult patients hospitalized at the University of Wisconsin Health System between 2009 and 2020 with an elevated eCART score, a validated clinical deterioration early warning score, on the medical-surgical wards. Patients with a chest radiograph within 48 hours prior to the elevated score were included in this study. Three computer vision model architectures (VGG16, Densenet121, Vision Transformer) and four data augmentation methods (Histogram Normalization, Random Flip, Random Gaussian Noise, and Random Rotate) were compared using the area under the receiver operating characteristic curve (AUROC) and the area under the precision-recall curve (AUPRC) for predicting clinical deterioration (i.e., intensive care unit transfer or ward death in the following 24 hours).

RESULTS

The study included 21,817 patient admissions, of which 1,655 (7.6%) experienced the outcome. Densenet121 model pre-trained on chest radiograph datasets with histogram normalization and random Gaussian noise augmentation had the highest discrimination (AUROC 0.734 and AUPRC 0.414), while vision transformer having 24 transformer blocks with random rotate augmentation had the lowest discrimination (AUROC=0.598).

CONCLUSIONS

The Densenet121 architecture pretrained with chest radiographs performed better than other architectures in most experiments, and the addition of histogram normalization with random Gaussian noise data augmentation may enhance performance for Densenet121 and pre-trained VGG16 architectures.

Objectives The purpose of this study is to explore the experiences of middle-aged women participating in the ‘Line Dance Dance Company’ as a form of serious leisure.
Methods This study aimed to understand the value and significance of line dance group activities in participants' lives. It employed a qualitative case study approach, specifically using a descriptive case study method. Data were collected through in-depth interviews with participants involved in line dance group activities. A total of six cases were analyzed using repetitive comparative analysis methods to identify common themes and insights. The study provides a rich and detailed description of the meanings and values that participants derive from their involvement in these activities.
Results First, the process of participating in line dance group activities was categorized into ‘glimpsing another world,’ ‘challenging: entering another world,’ ‘showing off oneself,’ and ‘re-challenging: entering another world.’ Through this process, the research participants' experiences can be interpreted as engaging in ‘serious leisure.’ Second, the meaning of the line dance group activity experience was derived as ‘discovering another version of oneself with passion and dedication,’ ‘expanding roles: being able to help,’ ‘restoring life subjectivity: living proactively for a wonderful self,’ and ‘happy life with a goal: preparing to be a wonderful grandmother.’
Conclusions Line dance company activities help participants discover their potential, enhance self-love, and maintain a positive perception of aging. In other words, these activities offer meaning and value beyond mere physical exercise, providing a serious and rewarding leisure experience. This study confirms that line dance group activities are valuable as they enable middle-aged women to anticipate their future with life subjectivity and goal setting. Therefore, programs that address various needs through group activities should be developed to serve as central points for middle-aged women's serious leisure activities.
