Tanaman alpukat (Persea americana Mill.) merupakan tanaman dari Amerika Tengah yang masuk ke Indonesia pada abad ke 18. Tanaman alpukat tumbuh subur di daerah tropis seperti Indonesia dan memiliki berbagai jenis alpukat yang berbeda-beda disetiap wilayah. Pertumbuhan tanaman dapat berjalan baik dikarenakan didukung oleh dua faktor yaitu faktor internal dan faktor eksternal. Faktor internal terdiri dari gen, hormon endogen dan umur tanaman. Faktor eksternal terdiri dari intensitas cahaya matahari, suhu udara, kelembaban udara, dan ketersediaan nutrisi. Jenis tanaman alpukat yang berbeda akan mempengaruhi respon pertumbuhan yang berbeda terhadap iklim. Penelitian bertujuan untuk mempelajari pertumbuhan beberapa jenis tanaman alpukat dalam hubungan dengan unsur iklim. Penelitian dilaksanakan pada bulan Juni sampai Oktober 2020 di Kebun alpukat Dukuh Blawu, Desa Permanu, Kecamatan Pakisaji, Kabupaten Malang. Metode penelitian menggunakan metode survei yang bersifat deskriptif. Pengumpulan data dilakukan dengan mengumpulkan data primer (waktu awal kuncup daun (flush) muncul, jumlah flush, diameter batang, jumlah cabang, dan jumlah daun) dan data sekunder (intensitas curah hujan, suhu udara, dan kelembaban udara). Analisis data yang digunakan yaitu analisis deskriptif yang didasarkan dari data primer dan data sekunder yang selanjutnya dilakukan uji korelasi antara unsur iklim dengan parameter yang diamati. Hasil penelitian menunjukkan bahwa tanaman alpukat jenis Miki pada variabel jumlah cabang dan jumlah daun dipengaruhi oleh curah hujan dan kelembaban udara.

Tot mijner gedachtenisse. Een vergelijking van de remonstrantse uitdelingswoorden bij het avondmaal met de gereformeerde
Authors: De Jong Klaas-Willem , Zwemer Sam
Published: October 2022

In 1640, the Remonstrants had liturgical forms for baptism and the Lord's Supper printed for the first time. This article takes a closer look at the words of administration at the Lord's Supper. In order to gain insight into the specific remonstrant position they are compared to the Reformed wording. This shows that the remonstrants placed particular emphasis on the Biblical justification of the wording used and on the connection with the London mother church and the first national synods in the Netherlands.

This work presents an ab initio study of the effect of a small addition of the third element of III and IV groups on the elastic and magnetoelastic properties of Fe75Ga25 alloy. The dependencies of the tetragonal elastic modulus C', magnetoelastic constant -b1, and the tetragonal magnetostrictive constant λ001 on the concentration of the Z-element in the cubic crystal structures A2 and D03 were obtained with the help of the density functional theory and the magnetic torque method in Fe75Ga25-xZx (Z=Al, Ge, Si) alloys (0≤ x≤6 at.%). It is shown that the addition of Al and Si atoms leads to an increase in the tetragonal elastic modulus compared to the Fe75Ga25 binary alloy. A correlation was established in the dependence equilibrium lattice constants a0(x) and λ001(x) in the studied ternary alloys for the A2 structure. Keywords: tetragonal magnetostriction constant, magnetoelastic constant, tetragonal shear modulus, magnetic torque method.

This work is devoted to the Monte Carlo simulation of the kinetics of phase transitions of the order-disorder type in the Fe80.5Ga19.5 alloy using the Blume--Emery--Griffiths Hamiltonian. The study of phase transformations was carried out in two stages: (1) different cooling rates (different number of Monte Carlo steps at a constant value of the binding energy); (2) isothermal annealing (the binding energy depends on the number of Monte Carlo steps at a fixed temperature). In the first case, a high cooling rate leads to one phase transition A2->D03+A2 at 700oC, while slow cooling leads to a transition A2->D03+A2 at 700oC through a mixture of phases A2, D03, B2 and L12 in the temperature range from 850 to 700oC. In the second case, an increase in the volume fraction of the L12 phase is shown with an increase in the duration of annealing at 750oC. Based on the data obtained, a thermokinetic diagram of phase transformations was constructed. Keywords: Monte Carlo method, Fe-Ga, phase transitions.
Study of the FCC-BCC phase transition in an Au-Fe alloy
Authors: Magomedov M. N.
Published: October 2022

The properties of the disordered Au-Fe substitution alloy are studied based on the analytical method, which uses the paired interatomic potential of Mie--Lennard-Jones. The parameters of the interatomic potential for the FCC and BCC structures of Au and Fe are determined. Based on these parameters, the concentration dependences of the properties of the FCC and BCC structures of the Au-Fe alloy are calculated. Under normal conditions (i.e., pressure P=0 and temperature T=300 K), changes in the properties of the Au-Fe alloy at the structural phase transition of FCC-BCC are calculated. Using the RP-model of the nanocrystal, the displacement of the Cf concentration, at which the FCC-BCC phase transition occurs, due to a decrease in the size of the nanoparticle was calculated. It is shown that at an isochoric-isothermal decrease in the number of atoms (N) in an Au-Fe nanoparticle, the Cf value displace towards higher Fe concentrations. For a nanoparticle with a fixed number of atoms and a constant surface shape, the Cf value increases at an isochoric increase in temperature, and the Cf value decreases at an isothermal decrease in density. Calculations have shown that at N<59900 for the Au1-CFeC alloy at P=0, T≤300 K and at any iron concentration, the FCC structure is more stable than the BCC structure. Keywords: gold, iron, substitution alloy, phase transition, state equation, elastic modulus, thermal expansion, nanoparticle, surface energy.

Investigation of transition metals effect on the phase composition, electrical and dielectric properties of diamond-like silicon-carbon films prepared by the plasma-chemical decomposition of polyphenylmethylsiloxane have been carried out. Frequency, temperature and concentration dependences of these properties are obtained. It is shown that an increase in the metal concentration in the film leads to a continuous increase in the electrical conductivity, while the concentration dependences of the dielectric constant and the dielectric loss tangent have a minimum at metal concentrations of 0.5-2 at.%. Possible reasons for this phenomenon are analyzed. Keywords: silicon-carbon films, transition metals, structure, electrical conductivity, dielectric constant, dielectric losses, concentration dependences, polarization.

The kinetics of the induced phase transition in single-crystal relaxor solid solutions PbMg1/3Nb2/3O3-29PbTiO3 and PbZn1/3Nb2/3O3-9PbTiO3 is studied when an electric field is applied along the [001] direction. At temperatures below the temperature of the morphotropic phase transition, the changes in the dielectric constant and optical transmission in electric fields are studied. It is shown that the decrease in optical transmission with time is associated only with a change in the sizes of nanoregions during the phase transition. It was found that the induced phase transition proceeds differently in these crystals. In PMN-29PT crystals, the formation of ferroelectric phases and the rapid establishment of macroscopic polarization are preceded by a certain delay time, while in PZN-9PT crystals, the ferroelectric phase is induced immediately after the application of the field without a delay time. The results obtained are explained by the different structures of the low-temperature phases in these compounds. Keywords: ferroelectricity, relaxors, induced phase transition.

High-frequency electron paramagnetic resonance (EPR) is used to study the unique properties of manganese centers in a GaAs : Mn crystal in strong magnetic fields at low temperatures. At frequencies of 94 and 130 GHz, EPR transitions were recorded in the MnGa2+-SH complex, which is a manganese ion with spin S=5/2, which replaces gallium (MnGa2+) and an ionized acceptor (A-) associated via an isotropic antiferromagnetic exchange interaction with a shallow hole (SH) with angular momentum J=3/2. A complex system of energy levels of this complex in a magnetic field and the possibility of accurately determining exchange interactions from EPR spectra are analyzed. Another complex was investigated, in which an ionized acceptor MnGa2+ interacts with a localized hole center in the form of a diamagnetic ion O2- replacing As. This complex, MnGa2+-OAs2-, is characterized by axial symmetry along the <111> axis of the cubic GaAs crystal and an anisotropic EPR spectrum. Due to the high Boltzmann factor, in our studies, the order of the fine structure spin levels of this complex was determined. The effect of the Boltzmann populations of the energy levels on the high-frequency EPR spectra was also demonstrated for the MnGa2+-SH complex. Keywords: high-frequency EPR, GaAs crystal, Mn acceptor, shallow hole, exchange interaction.

Published: October 2022

Background

Assisted reproductive technologies (ARTs) are considered to be physically and mentally stressful. During their treatment trajectory, couples express high information and communication needs. They appreciate using the internet to obtain fertility-related information. In a previous study, we developed myFertiCare, an eHealth tool providing personalized information and interactive functionalities for infertile couples in order to improve patient-centered care. The app has already been successful in qualitative evaluations of usability.

Objective

The aim of the current study is to quantitatively evaluate the implementation of myFertiCare by using the human, organizational, and technology–fit (HOT-fit) framework and to study the effects of using myFertiCare on couples’ knowledge about infertility, their experience of the burden of infertility, and their experience of patient-centered care. With these results, implementation can be further improved, and patient-centered care can be enhanced.

Methods

A quantitative study was performed based on the HOT-fit framework using validated questionnaires focusing on the human, organizational, and technology domains. Questions were added on the effect of using myFertiCare on couples’ knowledge about infertility and treatment. Questions regarding the burden of infertility, the burden of infertility treatment, and the experience of patient-centeredness were based on the main items of the validated fertility quality of life (FertiQoL) and Patient-Centredness Questionnaire–Infertility questionnaires, respectively. Also, nonusers of the app were included to explore motivations for not using the app and identify opportunities for improvement. Finally, user data were analyzed to provide insight into multiple variables concerning app use.

Results

In the human and technology domains, myFertiCare showed good system usability, high user satisfaction, and high information and interface quality. In the organizational domain, implementation was considered to be sufficient by both patients and staff. Use of the app increased knowledge about the treatment, improved coping with the treatment, and enhanced the experience of patient-centeredness. User data showed that women were the main app users and that use of the app gradually declined during the treatment trajectory.

Conclusions

A multi-faceted online app, myFertiCare, has been successfully evaluated quantitatively for implementation by using the HOT-fit framework. Use of the app increased knowledge about the treatment, improved coping with the treatment, and enhanced the experience of patient-centeredness. App use could be improved by creating more publicity. By providing myFertiCare, professionals in fertility care are supported in guiding patients through their treatment trajectory and in delivering patient-centered care.
Confluent and Reticulated Papillomatosis Resembling Pityriasis Versicolor and Acanthosis Nigricans: Case Report (Preprint)
Authors: David Abhinav , Srivastava Divyanshu
Published: October 2022

UNSTRUCTURED

Confluent and reticulated papillomatosis (CARP) is a rare disorder mostly seen in young adults. It is characterized by persistent dull-brown, centrally confluent, peripherally reticulate macules and papules, which coalesce to form patches and plaques on the upper trunk and neck. It is commonly confused with pityriasis versicolor and acanthosis nigricans (AN). We report the case of a 15-year-old male with multiple pigmented confluent and reticulated patches and plaques on the neck, trunk, and chin for 3 years, which was successfully treated with oral minocycline, resulting in complete resolution of lesions within 2 weeks. The morphology of CARP resembles that of various other dermatological conditions such as AN and pityriasis versicolor, and, as a result, it is frequently misdiagnosed and mistreated, leading to social embarrassment for the patient. Therefore, it is prudent for dermatologists to carry out comprehensive clinical and histopathological assessments to facilitate prompt diagnosis and management of this condition.

Authors: Zheng Miao , Li Teng , Zhong Hongling , Wang Jing , Chen Ji , Zhou Haizhou , Fan Yaojun , Peng Jing , Wang Fang , Wang Lihua
Published: October 2022

BACKGROUND

Increasing access to digital technologies drives market demands and productivity, whereas medical service quality can be improved by the implementation of digital self-scheduling among high-volume outpatient operations has not been verified.

OBJECTIVE

This study aims to investigate the impact of digital self-scheduling on outpatient appointment services (OAS) in hospital settings.

METHODS

Seven databases were searched through keywords and MeSH terms regarding ‘outpatient’, ‘appointments and schedules’, and ‘digital technology’ without restrictions on language or date. The quality assessment was conducted using GRADE criteria according to each study outcome. Meta-analysis was performed if the outcomes combined results from at least two studies. For dichotomous variables, original data were collected to calculate a Mantel-Haenszel odds ratio (OR) with 95% CIs. For continuous variables, an inverse variance probability weighted model was used to pool results to calculate Mean Difference (MD) or Standard Mean Difference (SMD) with 95% CIs. The MOOSE (the Meta-analysis Of Observational Studies in Epidemiology) guideline was applied to develop this study.

RESULTS

A total of 16 observational studies were included, involving 263,251 study participants in global medical hospitals or large health systems. The risk of bias was evaluated as acceptable, and the overall certainty of the evidence was low due to the non-randomized design of included studies. Compared with the traditional queuing method, digital self-scheduling resulted in a lower no-show event rate (OR=0.70, 95% CI: 0.57-0.85), an increased scheduling efficiency (OR=4.94, 95% CI: 4.54-5.38) and improved patient satisfaction (OR=2.83, 95% CI: 2.20-3.64) in OAS, but the waiting time spent from starting scheduling to the occurrence of consultation without significant difference. Younger age (MD -9.07, 95%CI: -14.75 to -3.38) and higher education (OR=0.86, 95% CI: 0.81-0.91) were observed in the digital self-scheduling population, while outpatient’s gender was not a statistically significant factor in their scheduling preference.

CONCLUSIONS

Our findings suggest that the implementation of digital self-scheduling can improve operational efficiency and patient experience of OAS in hospital settings. More rigorous study designs and targeted outcomes on patients and visits are warranted to verify the certainty of the effect estimates in future research.
Evolution of a Project to Improve Inpatient-to-Outpatient Dermatology Care Transitions: Mixed Methods Evaluation (Preprint)

Published: October 2022

BACKGROUND

In-hospital dermatological care has shifted from dedicated dermatology wards to consultation services, and some consulted patients may require postdischarge follow-up in outpatient dermatology. Safe and timely care transitions from inpatient-to-outpatient specialty care are critical for patient health, but communication around these transitions can be disjointed, and workflows can be complex.

OBJECTIVE

In this 3-phase quality improvement effort, we developed and evaluated an intervention that leveraged an electronic health record (EHR) feature, known as SmartPhrase, to enable a new workflow to improve transitions from inpatient care to outpatient dermatology.

METHODS

Phase 1 (February-March 2021) included interviews with patients and process mapping with key stakeholders to identify gaps and inform an intervention: a SmartPhrase table and associated workflow to promote collection of patient information needed for scheduling follow-up and closed-loop communication between dermatology and scheduling teams. In phase 2 (April-May 2021), semistructured interviews—with dermatologists (n=5), dermatology residents (n=5), and schedulers (n=6)—identified pain points and refinements. In phase 3, the intervention was evaluated by triangulating data from these interviews with measured changes in scheduling efficiency, visit completion, and messaging volume preimplementation (January-February 2021) and postimplementation (April-May 2021).

RESULTS

Preintervention pain points included unclear workflow for care transitions, limited patient input in follow-up planning, multiple messaging channels (eg, EHR based, email, and phone messages), and time-inefficient patient tracking. The intervention addressed most pain points; interviewees reported the intervention was easy to adopt and improved scheduling efficiency, workload, and patient involvement. More visits were completed within the desired timeframe of 14 days after discharge during the postimplementation period (21/47, 45%) than the preimplementation period (28/41, 68%; P=.03). The messaging workload also decreased from 88 scheduling-related messages sent for 25 patients before implementation to 30 messages for 8 patients after implementation.

CONCLUSIONS

Inpatient-to-outpatient specialty care transitions are complex and involve multiple stakeholders, thus requiring multifaceted solutions. With deliberate evaluation, broad stakeholder input, and iteration, we designed and implemented a successful solution using a standard EHR feature, SmartPhrase, integrated into a standardized workflow to improve the timeliness of posthospital specialty care and reduce workload.
The continuing concern over medication safety in China: propagating old-fashioned medicine over traditional communication channels (Preprint)
Authors: Lu Qianfeng , Schulz Peter J. , Chang Angela
Published: October 2022

BACKGROUND

Individuals’ perception of medication drug safety affects their adherence to their drug regime and through adherence to their health. China is among the countries with the largest number of medical drug consumers. Chinese citizens are facing a complex drug market that contains a variety of both traditional Chinese (TCM) and western medicine; meanwhile, the continuing safety scandals considerably impaired public confidence in medication drug. However, attention paid to their drug safety perception is few.

OBJECTIVE

Our study aims to answer a series of questions concerning drug safety perceptions in the Chinese context. We examined Chinese citizens' general drug safety perceptions and explored concerns about several frequently used drugs. Questions on how health information exposure and personal healthcare experience affect drug safety perceptions will be answered, and persons’ reliance on information sources in the drug safety crisis will be ascertained.

METHODS

Data from HINTS-China 2017 contains 3090 adults. The dataset was weighted before inferential analysis due to the overrepresentation of female respondents. We applied multiple linear regressions to examine the relations between drug safety perception and media exposure as well as personal healthcare experience. Respondents’ choice of unsafe drugs and information sources to rely on in drug safety crises were displayed in descriptive statistics.

RESULTS

Chinese people generally do not believe the current drug safety situation is satisfying and do not think it has improved in recent years. Their strong concerns are also reflected in their distrust in the safety antibiotics and vaccines. Exposure to Internet health information was negatively associated with drug safety perception (Drug safety quo: β = -.149, p < .001; drug safety amelioration (β = -.065, p= .042). However tradition media exposure was positively correlated (Drug safety quo: β = 121, p < .001; drug safety amelioration β = .107, p < .001). Satisfaction with health care services positively linked to safety perception (Drug safety quo: β = .271, p < .001; drug safety amelioration β = .182, p < .001). Physicians were considered the most reliable group in drug safety incidents.

CONCLUSIONS

Chinese citizens’ concerns about drug safety were accompanied by strong distrust in antibiotics and vaccines. Several determinants of safety perceptions were identified including internet health information exposure, traditional media health information exposure and personal healthcare experiences. New insights into the role of physicians were added to the literature by showing the firmest reliance on health information from physicians in drug safety incidents.
Cognitive Bias Modification Training Targeting Fatigue in Patients With Kidney Disease: Usability Study (Preprint)
Authors: Geerts Jody , Pieterse Marcel , Laverman Goos , Waanders Femke , Oosterom Nicole , Slegten Jacqueline , Salemink Elske , Bode Christina
Published: October 2022

BACKGROUND

Fatigue is an important symptom for many patients, including patients with kidney disease. Cognitive biases, such as attentional bias and self-identity bias, are thought to influence fatigue. Cognitive bias modification (CBM) training is a promising technique to counter fatigue.

OBJECTIVE

We aimed to evaluate a CBM training among patients with kidney disease and health care professionals (HCPs) and assess acceptability and applicability in the clinical setting using an iterative design process to evaluate expectations and experiences with the training.

METHODS

This was a longitudinal, qualitative, and multiple stakeholder–perspective usability study in which we interviewed end users and HCPs during the prototyping phase and after the end of training. We conducted semistructured interviews with 29 patients and 16 HCPs. The interviews were transcribed and analyzed thematically. Next to a general evaluation of the training, the acceptability of the training was evaluated using the Theoretical Framework of Acceptability, and applicability was assessed by evaluating obstacles and solutions for implementation in the kidney care setting.

RESULTS

Generally, participants were positive about the training and its applicability. The biggest negatives were doubts about effectiveness and annoyance about the repetitive character of CBM. Acceptability was judged with a mixed evaluation, with a negative evaluation of perceived effectiveness; mixed results for burden, intervention coherence, and self-efficacy; and positive results for affective attitude, ethicality, and opportunity costs. Barriers for applicability were patients’ varying computer skills, subjectivity of fatigue, and integration with regular treatment (eg, the role of HCPs). Possible solutions included assigning representatives among nurses, offering training on an app, and providing assistance via a help desk. The iterative design process, including repeated waves of testing user expectations and experiences, yielded complementary data.

CONCLUSIONS

To the best of our knowledge, this study is the first to introduce a CBM training targeting fatigue. Furthermore, this study provides one of the first user evaluations of a CBM training, both among patients with kidney disease and their care providers. Overall, the training was evaluated positively, although acceptability showed mixed results. Applicability was positive although barriers were identified. The proposed solutions require further testing, preferably following the same frameworks, as the iteration in this study contributed positively to the quality of the training. Therefore, future research should follow the same frameworks and consider stakeholders and end users in eHealth intervention design.
Development of artificial intelligence model for predicting in-hospital mortality derived from international classification of diseases, triage scales, procedure codes, and other clinical features in trauma patients: A nationwide population-based study (Preprint)
Authors: Lee Seung Seok , Kang Wu Seong , Seo Sang Hyun , Kim Do Wan , Ko Hoon , Kim Joongseok , Lee Seonghwa , Lee Jinseok
Published: October 2022

BACKGROUND

Trauma-related mortality is a heavy burden. Estimating the mortality risk in trauma patients is crucial to enhance treatment efficiency and reduce the burden. The most popular and accurate model is the injury severity score based on the abbreviated injury scale (AIS), which is an anatomical injury severity scoring system. However, the AIS requires specialists to code the injury scale by reviewing a patient's medical record; therefore, applying the model to every hospital is impossible.

OBJECTIVE

We aimed to develop an artificial intelligence (AI) model to predict in-hospital mortality in trauma patients using the international classification of disease (ICD)-10, triage scale, procedure codes, and other clinical features.

METHODS

We used the Korean National Emergency Department Information System (NEDIS) dataset (n=778,111) from over 400 hospitals from 2016 to 2019. To predict in-hospital mortality, we used ICD-10; patient’s age; gender; intentionality; injury mechanism; emergent symptom; AVPU scale; Korean triage and acuity scale (KTAS); and procedure codes as input features. We proposed the ensemble of deep neural networks (EDNN) via five-fold cross-validation, and compared with other state-of-the-art machine learning models, including traditional prediction models. We further investigated the effect of features.

RESULTS

Our proposed EDNN with all features provided the highest AUROC of 0.9507, which outperformed other state-of-the-art models, including traditional prediction models: AdaBoost (AUROC of 0.9433), XGBoost (AUROC of 0.9331), ICD-based injury severity score (AUROC of 0.8699 an inclusive model and AUROC of 0.8224 an exclusive model), and KTAS (AUROC of 0.1841). In addition, using all features provided higher AUROC than any other partial features: EDNN with the features of ICD-10 only (AUROC of 0.8964) and EDNN with the features excluding ICD-10 (AUROC of 0.9383).

CONCLUSIONS

Our proposed EDNN with all features outperforms other state-of-the-art models, including the traditional diagnostic code-based prediction model and triage scale.

Untuk meningkatkan kewaspadaan dini pada penyakit infeksi new-emerging dan re-emerging, khususnya penyakit Mers-CoV dan Ebola, maka diperlukan suatu alat yang dapat membantu Dinas Kesehatan dalam melakukan pemantauan pada dengan perjalanan dari dan keluar negri.Tujuan: Penelitian ini bertujuan untuk melakukan pengembangan terhadap sistem kewaspadaan dini penyakit New-Emerging dan Re-Emerging dengan berfokus pada kasus penyakit Mers-Cov dan Ebola di kantor Kesehatan Pelabuhan Soekarno-Hatta.Metode: Penelitian ini merupakan penelitian kualitatif, data diperoleh melalui tehnik tehnik wawancara, studi literatur dan observasi lapangan. Metode yang digunakan dalam pengembangan sistem ialah System Development Life Cycle (SDLC) Waterfal.Hasil: Data hasil wawancara, observasi, dan analisis dokumen diperoleh sistem informasi yang dimiliki KKP Soekarno-Hatta sudah memadai namun tidak didukung dengan kelengkapan software pencatatan pada setiap computer, petugas KKP juga masih melakukan pencatatan manual, sehingga berdampak pada keterbatasan mengakses data, waktu pengolahan data, dan keterlambatan pada pelaporan data. Sistem kewaspadaan dini didesign menghasilkan laporan airline serta laporan kunjungan pasien secara otomatis. Untuk menjamin keamanan sistem dibatasi 20 menit pada waktu entry, dilengkapi username dan password. Pada proses pengujian system menggunakan Blackbox Testing. Kesimpulan: Prototype sistem kewaspadaan dini penyakit infeksi new-emerging dan re-emerging masih perlu dilakukan sosialisasi terutama terkait penggunaannya.  Kata Kunci: sistem kewaspadaan dini, mers-cov, ebola

Authors: Setiawan Prayudha Benni , Hartono Prof. Dr. DEA, DESS
Published: October 2022

Latar Belakang: Penyakit periodontal adalah kerusakan patologis yang mengenai jaringan pendukung gigi. Patogenesisnya sebagian besar dipengaruhi oleh kondisi sistemik. Selain itu faktor geografis, lingkungan, perilaku kesehatan gigi dan sosiekonomi dapat mempengaruhi individu mengalami penyakit periodontal. Sistem Informasi Geografis (SIG) dapat digunakan untuk menganalisa perbedaan faktor-faktor tersebut, terutama yang berhubungan dengan perbedaan geografis, faktor-faktor demografis, budaya dan lain-lain. Kecamatan Pundong memiliki variasi letak geografis dan sosial ekonomiMetode: Jenis penelitian ini adalah observasional analitik survei dengan disain cross sectional. Subjek penelitian ditetapkan dengan pendekatan Regristry Based Study dimana Puskesmas Pundong sebagai sumber data dasar dalam penelitian ini. Variabel bebas adalah penyakit periodontal, sedangkan variable terikat adalah faktor sosioekonomi, perilaku kesehatan, jarak ke sarana pelayanan kesehatan (geografis) dan pH air (lingkungan). Analisis spasial menggunakan SatScan dan ArcGIS.Hasil: Variabel yang berhubungan secara signifikan dengan keparahan penyakit periodontal yaitu status ekonomi, perilaku menyikat gigi, pH sumber air dan ketinggian tempat (p-value<0,05). Analisis buffer terhadap pelayanan kesehatan, sebagian besar penderita penyakit periodontal bertempat tinggal dekat dengan pelayanan kesehatan. Analisis spasial untuk mengetahui pengelompokan (cluster) kejadian penyakit periodontal, dengan analisis Purely Spatial Poisson Model didapat 1 cluster, terjadi pada 49 penderita dengan radius 2.24 km terdapat di Desa Seloharjo dengan nilai p-value = 1,00. Hal ini dikarenakan pola persebaran penyakit periodontal tidak berdasarkan pada tempat-tempat tertentu. Memiliki annual cases 11.2/100000 penduduk, yang berarti dalam 100000 penduduk memiliki kasus 11.2 orang.Kata Kunci: Penyakit Periodontal, Sosio ekonomi, Perilaku, Geografis, Lingkungan, SIG

Authors: Saputro Niko Tesni
Published: October 2022

Latar Belakang: Disintegrasi data kesehatan masih terjadi tidak hanya di tingkat pusat, melainkan juga di tingkat provinsi hingga kabupaten/kota, termasuk di dinas kesehatan di Daerah Istimewa Yogyakarta. Disintegrasi data bisa berdampak terhadap kualitas kebijakan kesehatan yang dihasilkan, maka perlu dilakukan integrasi data. WHO menyerukan penggunaan data repository untuk integrasi data. DHIS2 hadir sebagai data repository yang dapat memenuhi kebutuhan daerah dan pusat. Belum pernah dilakukan penelitian terkait integrasi data berbasis program kesehatan di dinas kesehatan di Daerah Istimewa Yogyakarta, khususnya menggunakan aplikasi DHIS2.Tujuan: Mengeksplorasi proses integrasi data berbasis program kesehatan di dinas kesehatan tingkat provinsi maupun kabupaten/kota di Daerah Istimewa Yogyakarta.Metode : Jenis penelitian yang digunakan adalah penelitian action research. Penelitian ini dilakukan di Dinas Kesehatan Daerah Istimewa Yogyakarta, juga termasuk dinas kesehatan kabupaten/kota di Daerah Istimewa Yogyakarta. Penelitian ini dilakukan pada bulan Juli 2018 - Februari 2019.Hasil: Rangkaian kegiatan integrasi data menggunakan aplikasi DHIS2 dilaksanakan dengan melibatkan pengelola program kesehatan di masing-masing dinas kesehatan dalam tiga tahapan kegiatan, meliputi: tahapan sosialisasi, pelatihan dan analisis kebutuhan, tahapan pengembangan dan tahapan diseminasi dan evaluasi. Sumber data yang terkumpulkan pada tahapan analisis kebutuhan, sosialisasi dan pelatihan meliputi KIA, Gizi, Surveilans, SDMK, Promkes, Keswa, LB1 dan LB4, Imunisasi, Diare, ISPA dan DBD. Masih ada kendala teknis yang apabila tidak diatasi, maka akan menambah waktu yang diperlukan untuk integrasi data menggunakan aplikasi DHIS2, yakni tata desain formulir pelaporan rutin belum terstandar. Kendala non-teknis yang utama yakni terkait standarisasi dan regulasi tertulis yang mengatur tentang integrasi data.Kesimpulan: Integrasi data berbasis program kesehatan di Dinas Kesehatan Daerah Istimewa Yogyakarta dilaksanakan melalui strategi berupa pelaksanaan pertemuanpertemuan dalam rangkaian kegiatan integrasi data menggunakan aplikasi DHIS2. Terdapat kendala-kendala pada pelaksanaan kegiatan integrasi data menggunakan aplikasi DHIS2 yang dapat dikelompokkan menjadi kendala teknis dan kendala non-teknis. Solusi untuk masing-masing kendala pada pelaksanaan kegiatan integrasi data menggunakan aplikasi DHIS2 perlu dilakukan. Diperlukan peningkatan atau perbaruan strategi integrasi data yang dapat dilakukan pada siklus selanjutnya. Kata Kunci: Integrasi, Program Kesehatan, DHIS2

Authors: Rohman Hendra , Hartono Hartono , Probandari Ari Natalia
Published: October 2022

Latar Belakang: Penderita DM lebih rentan terkena TB. Penderita TB paru dengan dan tanpa DM di Kulon Progo tahun 2014 sebanyak 174 orang. Pengolahan register TB masih terbatas pada analisis tabuler. Pengelolaan penderita TB paru terkait dengan keberlangsungan pengobatan masih terbatas. Analisis TB masih berupa agregasi data di tingkat kelurahan, belum berupa pemetaan penderita.Metode Penelitian: Survei cross-sectional menggunakan sistem informasi geografis, dengan populasi wilayah dan penderita TB Paru 2014, sampel sebanyak 162 orang. Variabel terikat adalah TB paru, dan TB paru dengan riwayat DM (TB-DM). Variabel bebas adalah jarak ke sarana pelayanan kesehatan, pendapatan dan DM. Analisis spasial menggunakan SaTScan, GeoDa, dan ArcGIS.Hasil: Pola spasial distribusi penderita TB paru dengan dan tanpa DM sebagian besar berada di wilayah dengan intensitas curah hujan tinggi, dan terdapat clustering di pedesaan, dengan pendapatan rendah, jauh dari sarana pelayanan kesehatan. Space time permutation model menunjukkan terdapat 5 cluster TB paru, namun tidak signifikan. Hasil spatial error model menunjukkan, secara spasial, pendapatan dan jarak ke sarana pelayanan kesehatan memiliki hubungan dengan kejadian TB paru. Di wilayah prevalensi tinggi DM teridentifikasi jumlah sumber daya medis yang sedikit. TB-DM berada di wilayah prevalensi tinggi DM, dan sebagian besar di pedesaan. Terdapat hubungan yang signifikan antara populasi DM dengan kejadian TB-DM, namun secara spasial tidak. Kejadian TB paru dengan pengobatan ulang, sebagian besar di pedesaan, dan akses sulit, pencarian tempat pengobatan di beberapa sarana pelayanan kesehatan hingga pindah di 4 tempat yang berbeda. Kesimpulan: Kejadian TB paru terjadi seiring dengan musim hujan. Pola clustering kejadian TB paru di pedesaan, dengan pendapatan rendah, dan jauh dari sarana pelayanan kesehatan, spatial error model menunjukkan ketergantungan spasial. Hubungan antara populasi DM dengan kejadian TB-DM signifikan, namun secara spasial tidak.Kata Kunci: diabetes mellitus, distance perception, geographic information system, low income, mycobacterium tuberculosis
Prevalent Genres of Preaching and Its Significance to Young People in this Time of Pandemic
Authors: Udofia Stephen Nwanaokuo
Published: October 2022

Preaching is a scriptural interpretation of human existence which enables a community to recognize God’s active presence, respond to that presence in faith through liturgical word and gesture, and beyond the liturgical assembly, through a life lived in conformity with the Gospel. Through the act of preaching, the preacher ought to reveal people’s hearts to themselves, give them the power to make judgments that liberate them, and imbue in them the confidence to face their fears with faith, hope and love. Given that young people today, (especially in this time of pandemic) are hungry and sometimes desperate for meaning in their lives, there ought to be a shift in preaching from mere scriptural interpretation to a kind of preaching which takes into consideration the concrete, existential and phenomenological realities of young people. This kind of preaching ought to assume a prophetic dimension if it is to effectively cater to young people or assure unwavering hope in this time of the pandemic (new-normal). In what follows, the paper critically examines some prevalent genres of preaching, how these genres of preaching cater to young people, and the most suitable genre of preaching to be adopted for use in the Nigerian Church today.
