Tujuan dari penelitian ini adalah untuk menganalisis pengaruh variasi jenis tanaman barier terhadap dinamika populasi serangga hama pada tanaman padi dan produktivitas tanaman padi. Penelitian ini dilakukan di Kebun Percobaan Fakultas Pertanian UGM Banguntapan Bantul. Variabel bebas dari penelitian ini adalah perlakuan variasi tanaman barier yaitu kontrol (tanpa barier), gulma alami, bunga matahari, dan bunga kenikir. Variabel terikatnya adalah dinamika populasi serangga hama dan produktivitas tanaman padi. Pengamatan serangga hama dan musuh alaminya dilakukan terbatas pada pagi hari antara pukul 08.00-11.00 dengan metode scan sampling yang dilakukan pada 3 minggu sekali. Data produktivitas tanaman padi yang diambil meliputi berat kering gabah hasil panen per plot perlakuan. Untuk melihat pengaruh perlakuan variasi jenis tanaman barier terhadap populasi serangga hama tanaman padi dan produktivitas tanaman padi dilakukan uji ANOVA. Hasil penelitian menunjukkan tidak terdapat perbedaan yang signifikan dari pengaruh variasi jenis tanaman barier terhadap perbedaan dinamika populasi serangga hama maupun terhadap produktivitas tanaman padi, tetapi perlu diadakan penelitian lanjutan yang dikaitkan dengan variabel lain yang mempengaruhi produktivitas tanaman padi.THE EFFECT OF BARRIER PLANT VARIATION AS NATURAL PEST CONTROL ON PEST POPULATION AND RICE PRODUCTIONThis study was aimed at analyzing the effect of the barrier plant variation to the population dynamic of rice pest insect and on rice crop productivity. The study was conducted in the experimental Garden of Faculty of Agriculture of Gadjah Mada University in Banguntapan Bantul. The independent variable was the treatment of barrier plant variation, i.e. control (without barrier), natural weed, sunflower and kenikir flower plants, while the dependent variables were population dynamic of pest insect and rice crop productivity. Pest insects and their natural enemies observation was carried out in between 08.00-11.00 am by scan sampling every 3 weeks. The retrieval of crop productivity data was done when the harvest per treatment plot. The data obtained was then tested with ANOVA, to find out the effect of the treatments on population dynamic of rice crop pest, as well as rice crop productivity. The results show that there was no significant difference in the effect of barrier plant variation to the differences in population dynamic of pest insects; as well as in the productivity of rice crop, but it is necessary to conduct advanced research that is associated with other variables that affect rice crop productivity.

In this paper we showed that illumination of both front and back sides of heterojunction solar cells contribute efficiency. The obtained spectral dispersion of quantum efficiency confirms that contribution depends on conversion of short-wave photonts. The average difference between quantum efficiency of both sides is ∼ 11%. Under standard solar illumination in the 400−1100 nm wavelength range the short-current density for front side is 36.3 mA/cm² and 32.7 mA/cm² for back side with reduction about 10%.

La competitividad en el campo mexicano se asocia a productores con una estructura organizacional formal y conscientes de ser parte medular dentro de la cadena de valor agrícola. En el estado de Guanajuato, México, los mercados para los pequeños productores son principalmente locales y continuamente sobreviven gracias a los apoyos gubernamentales. Para mejorar la competitividad, las organizaciones han usado tecnologías de la información y la comunicación (TIC). Por lo tanto, el objetivo de la presente investigación fue el de comprobar que la asimilación de TIC en los pequeños productores de agricultura protegida es una estrategia que influye en la mejora de la competitividad de sus unidades de producción (UP). Para alcanzar el objetivo, se adecuó la Matriz de Análisis de Políticas (MAP) para calcular los niveles de competitividad, así como el Modelo de Aceptación Tecnológica (TAM), a partir de la teoría de la acción razonada (TRA) para determinar las actitudes que influyen en la conducta y poder calcular los niveles de asimilación de TIC. Se obtuvo como resultado principal una relación altamente significativa entre la competitividad y la asimilación de TIC. Con lo anterior, se concluyó que el nivel de competitividad en los pequeños productores de agricultura protegida está altamente asociado al nivel de asimilación de las TIC. Se recomienda ampliamente a los productores esforzarse para incorporarlas en su toma de decisiones y administración de sus UP.

Background

Web-based interventions for depression have been widely tested for usability and functioning. However, the few studies that have addressed the therapeutic quality of these interventions have mainly focused on general aspects without consideration of specific quality factors related to particular treatment components. Clinicians and scientists are calling for standardized assessment criteria for web-based interventions to enable effective and trustworthy patient care. Therefore, an extensive evaluation of web-based interventions at the level of individual treatment components based on therapeutic guidelines and manuals is needed.

Objective

The objective of this study was to evaluate the quality of unguided web-based interventions for depression at the level of individual treatment components based on their adherence to current gold-standard treatment guidelines and manuals.

Methods

A comprehensive online search of popular app stores and search engines in January 2018 revealed 11 desktop programs and 17 smartphone apps that met the inclusion criteria. Programs and apps were included if they were available for German users, interactive, unguided, and targeted toward depression. All programs and apps were tested by three independent researchers following a standardized procedure with a predefined symptom trajectory. During the testing, all web-based interventions were rated with a standardized list of criteria based on treatment guidelines and manuals for depression.

Results

Overall interrater reliability for all raters was substantial with an intraclass correlation coefficient of 0.73 and Gwet AC1 value of 0.80. The main features of web-based interventions included mood tracking (24/28, 86%), psychoeducation (21/28, 75%), cognitive restructuring (21/28, 75%), crisis management (20/28, 71%), behavioral activation (19/29, 68%), and relaxation training (18/28, 64%). Overall, therapeutic meaningfulness was rated higher for desktop programs (mean 4.13, SD 1.17) than for smartphone apps (mean 2.92, SD 1.46).

Conclusions

Although many exercises from manuals are included in web-based interventions, the necessary therapeutic depth of the interventions is often not reached, and risk management is frequently lacking. There is a need for further research targeting general principles for the development and evaluation of therapeutically sound web-based interventions for depression.

Published: July 2020

Background

Many mobile health (mHealth) technologies exist for patients with heart failure (HF). However, HF mhealth lacks evidence of efficacy, caregiver involvement, and clinically useful real-time data.

Objective

We aim to capture health care providers’ perceived value of HF mHealth, particularly for pairing patient–caregiver-generated data with clinical intervention to inform the design of future HF mHealth.

Methods

This study is a subanalysis of a larger qualitative study based on interviewing patients with HF, their caregivers, and health care providers. This analysis included interviews with health care providers (N=20), focusing on their perceived usefulness of HF mHealth tools and interventions.

Results

A total of 5 themes emerged: (1) bio-psychosocial-spiritual monitoring, (2) use of sensors, (3) interoperability, (4) data sharing, and (5) usefulness of patient-reported outcomes in practice. Providers remain interested in mHealth technologies for HF patients and their caregivers. However, providers report being unconvinced of the clinical usefulness of robust real-time patient-reported outcomes.

Conclusions

The use of assessments, sensors, and real-time data collection could provide value in patient care. Future research must continually explore how to maximize the utility of mHealth for HF patients, their caregivers, and health care providers.

BACKGROUND

The global shortage of mental health workers has prompted the utilization of technological advancements, such as chatbots, to meet the needs of people with mental health conditions. Chatbots are systems that are able to converse and interact with human users using spoken, written, and visual language. While numerous studies have assessed the effectiveness and safety of using chatbots in mental health, no reviews have pooled the results of those studies.

OBJECTIVE

This study aimed to assess the effectiveness and safety of using chatbots to improve mental health through summarizing and pooling the results of previous studies.

METHODS

A systematic review was carried out to achieve this objective. The search sources were 7 bibliographic databases (eg, MEDLINE, EMBASE, PsycINFO), the search engine “Google Scholar,” and backward and forward reference list checking of the included studies and relevant reviews. Two reviewers independently selected the studies, extracted data from the included studies, and assessed the risk of bias. Data extracted from studies were synthesized using narrative and statistical methods, as appropriate.

RESULTS

Of 1048 citations retrieved, we identified 12 studies examining the effect of using chatbots on 8 outcomes. Weak evidence demonstrated that chatbots were effective in improving depression, distress, stress, and acrophobia. In contrast, according to similar evidence, there was no statistically significant effect of using chatbots on subjective psychological wellbeing. Results were conflicting regarding the effect of chatbots on the severity of anxiety and positive and negative affect. Only two studies assessed the safety of chatbots and concluded that they are safe in mental health, as no adverse events or harms were reported.

CONCLUSIONS

Chatbots have the potential to improve mental health. However, the evidence in this review was not sufficient to definitely conclude this due to lack of evidence that their effect is clinically important, a lack of studies assessing each outcome, high risk of bias in those studies, and conflicting results for some outcomes. Further studies are required to draw solid conclusions about the effectiveness and safety of chatbots.
