BACKGROUND

In recent years, the rapid development of mobile medical technology has provided multiple ways for the long-term management of chronic diseases, especially diabetes. As a new type of management model, smartphone apps are global, convenient, cheap, and interactive. Although apps were proved to be more effective at glycemic control, compared with traditional computer- and Web-based telemedicine technologies, how to gain a further and sustained improvement is still being explored.

OBJECTIVE

The objective of this study was to investigate the effectiveness of an app-based interactive management model by a professional health care team on glycemic control in Chinese patients with poorly controlled diabetes.

METHODS

This study was a 6-month long, single-center, prospective randomized controlled trial. A total of 276 type 1 or type 2 diabetes patients were enrolled and randomized to the control group (group A), app self-management group (group B), and app interactive management group (group C) in a 1:1:1 ratio. The primary outcome was the change in glycated hemoglobin (HbA1c) level. Missing data were handled by multiple imputation.

RESULTS

At months 3 and 6, all 3 groups showed significant decreases in HbA1c levels (all P<.05). Patients in the app interactive management group had a significantly lower HbA1clevel than those in the app self-management group at 6 months (P=.04). The average HbA1c reduction in the app interactive management group was larger than that in the app self-management and control groups at both months 3 and 6 (all P<.05). However, no differences in HbA1c reduction were observed between the app self-management and control groups at both months 3 and 6 (both P>.05). Multivariate line regression analyses also showed that the app interactive management group was associated with the larger reduction of HbA1c compared with groups A and B at both months 3 and 6 (all P>.05). In addition, the app interactive management group had better control of triglyceride and high-density lipoprotein cholesterol levels at both months 3 and 6 compared with baseline (both P<.05).

CONCLUSIONS

In Chinese patients with poorly controlled diabetes, it was difficult to achieve long-term effective glucose improvement by using app self-management alone, but combining it with interactive management can help achieve rapid and sustained glycemic control.

Authors: Stamatiou Pavlos , Dritsakis Nikolaos
Published: July 2019

This paper investigates the effect of Foreign Direct Investment (FDI) on economic growth in Greece, within a framework that also accounts unemployment rate, using annual data covering the period 1970 to 2017. Several econometric models are applied including the ARDL bound test approach for cointegration as well as ECM-ARDL model for causality. The results of the study confirm the existence of a long run relationship among the examined variables. The Granger causality results indicated a strong unidirectional causality between economic development and foreign direct investments with direction from economic development to foreign direct investments. Finally, the variance decomposition method and the impulse response functions are used to test the strength of causality between the variables. The results of the study offer new perspectives and insight for new policies for sustainable economic development, increasing investments and reducing unemployment.

Published: July 2019

Palm oil is comparable to traditional diesel fuel in terms of calorifi c value, stoichiometric ratio, and cetane number. However, its increased kinematic viscosity and pour point make it diffi cult to use in pure form in diesel engines. (Research purpose) To study specifi c features of burning: diesel fuel with various additives of palm oil (biodiesel fuel); pure 100-percent palm oil; biodiesel fuel with various additives of palm oil and hydrogen peroxide, as well as to develop a method to control its combustion process. (Materials and methods) To determine the ignition time lag, the authors chose a method of kinetic modeling of self-ignition of biodiesel fuel in the air. The self-ignition process was simulated using the Chemical Workbench software package. An adiabatic calorimetric bomb model was used to perform calculations. To describe the process of self-ignition, a universal kinetic mechanism was used, which was verifi ed to calculate self-ignition of diesel and biodiesel fuel surrogates, as well as the formation of toxic substances and soot in the combustion processes. (Results and discussion) It is shown that adding palm oil to diesel fuel increases its ignition time lag, especially at low and medium temperatures of 750-950 kelvin. It was determined that with addition of 10 percent palm oil, the ignition time lag of biodiesel fuel is almost the same as that of diesel fuel no more than 5 percent. Increasing the amount of palm oil additive up to 30 percent and more signifi cantly increases the ignition time lag of the fuel. When using only palm oil as a fuel, the ignition time lag in the temperature range of 800-950 kelvin increases in two times. The study determined the optimal amount of hydrogen peroxide to be used for each composition of biodiesel fuel with various additives of palm oil. (Conclusions) It is shown that additives of hydrogen peroxide can infl uence the reactivity of biodiesel fuel and thereby regulate its ignition time lag.

Published: July 2019

Banda export nutmeg and mace commodities which are rich in essential oils make this plant one of the export commodities on the international market. Banda Neira with the sub-district center located on the island of Neira is one of the Districts in Central Maluku Regency which has the highest amount of nutmeg production, and is a natural spice of the Banda Islands and is known as the nutmeg Banda. This study aims to analyze the nutmeg marketing channel Banda in Banda Neira District, Central Maluku Regency. Sampling uses the random sampling method using a lottery. The data analysis method used is a quantitative analysis approach. The results showed that the in-depth knowledge of farmers about the handling of lean crops coupled with the discovery of aflatoxin which resulted in Banda nutmeg being rejected by international markets, this became a dilemma for exporters whose focus was on small farmers who in their post-harvest processing did not meet international quality standards. This is also triggered by the share received by farmers as the main marketing actor, which is much smaller than other marketing institutions that contribute to the Banda nutmeg marketing chain, so that handling and marketing seems not right, and strategies for more efficient marketing channel analysis are needed that is through the role of marketing institutions involved in developing and marketing nutmeg commodities. There was 70 percent of respondents (42 people) involved in the short marketing channel, through subdistrict traders and 30 percent (18 people) farmers engaged in the long marketing channel through village collectors with different levels of prices charged by each marketing agency.

The purposes of the study was to isolate, to characterize, and to identify rhizobacteria from plant rhizosphere growing in gold and copper mine. The isolation of rhizobacteria used N-free semisolid agar media, TSA, and SLP plus heavy metals (HMs), namely Pb, Cd, and or Cu. Isolated rhizobacteria were subsequently characterized for resistance to higher level of Pb, Cd, Cu in SLP media. Cultural and morphological characterization of rhizobacteria were conducted for cell morphology, motility, Gram staining, and biofilm formation. The rhizobacteria identification used sequence analysis of the 16S RNA gene fragments. The results showed that the majority of rhizobacterial from Cu mine site (66.7% of 21 isolates) were resistant to Cu (72150 ppm) while the majority of rhizobacteria from gold mine site (77.8% of 18 isolates) were sensitive to 72 ppm Cu. Majority of Cu in the soil was insoluble as granules attaching to gravel so that rhizobacteria of Cu mine site have been exposed and adapted to available Cu. This fact, explaining that the rhizobacteria’s MIC value was lower than the total Cu level in the soil. Three HMs-resistant rhizobacter (PbSM 2.1, MGR 334, and CuNFbM 4.1) formed biofilms, which was as one of the resistance mechanism to HMs. This research informed that HM contaminated-soil is better source for obtaining HM resistant rhizobacteria than HM uncontaminated-soil. The use four isolation media produce rhizobacteria which was more diverse than rhizobacteria from each isolation medium. Further characterization needs to be done to obtain HM resistant-rhizobacteria which can be used as biofertilizers and phytoremediation agent.

Decentralization has been regarded as a best way to utilize natural resources for local people benefit and to distribute development results fairly through out of entirely of the country. However, experience has shown that in some cases decentralization in forest management policy was not implemented by local authorities in balancing way of both utilization and conservation. On the other hand, local government complained that even though power transfer to local authority has been implemented since the Indonesian reform politic, central government is still maintaining control over the forest management policy. This article describes decentralization experiences of forest management policy in South Sulawesi. Their impacts followed by some suggestions are also outlined.

CHALLENGES FOR CONSERVATION OF SULAWESI CRESTED BLACK MACAQUE (Macaca nigra)
Authors: Maulany Risma Illa
Published: July 2019

Macaca nigra (kera jambul hitam) adalah salah satu satwa endemik di Pulau Sulawesi yang populasinya di alam semakin berkurang. Menurunnya populasi satwa ini utamanya disebabkan oleh meningkatnya populasi penduduk yang secara tidak langsung mempengaruhi tingkat perburuan satwa ini, yang umumnya dikonsumsi sebagai makanan tradisional masyarakat setempat. Perburuan ini dilakukan semata-mata hanya untuk tujuan komersial. Akses jalan Trans-Sulawesi yang semakin baik juga telah membuka peluang yang lebih besar bagi para pemburu dan pedagang dalam melakukan perdagangan satwa liar. Selain itu, status kawasan, lemahnya penegakan hukum, minimnya sumberdaya manusia pengelola kawasan, dan lemahnya manajemen kawasan serta aktivitas wisata yang tidak bertanggung jawab juga turut berperan dalam menurunnya populasi kera jambul hitam. Tulisan ini mencoba untuk mengetengahkan isu-isu yang mempengaruhi populasi M. nigra di alam dan mengidentifikasi tantangan-tantangan yang harus dihadapi dalam konservasi satwa ini. Rekomendasi untuk mempertahankan populasi dan melestarikan satwa ini juga dibahas dalam tulisan ini.

The intensive use of Eboni has caused a decrease of its natural population which has also contributed to the future loss of genetic potencies. Preservation efforts could only be conducted if the actual potencies of the stand and its environmental conditions were recognized. A study on stand and regeneration potencies as well as its soil characteristics is needed as a basic in management aplication for the increase of genetic potencies. This study used a systematic sampling survey method and laboratory analysis. The study aims to identify tree potencies and regeneration of Eboni Makassar as well as its soil characteristics under the stand. The results are expected to provide a description on Eboni Makassar potencies and its management efforts. It was found from the study that the potency of Eboni was 5.013 m3/ha with minimum and maximum estimated volumes of 3.163 m3/ha and 6.863 m3/ha, respectively. Eboni was naturally regenerated better in >40% slope category.

Sub watershed of Mowewe has been considered as important regions in South East Sulawesi because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which have been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Mowewe sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Universal Soil Loss Equation (USLE) model based on Geographical Information Systems (GIS). The result of the research revealed that the predicting soil erosion is 68,58 ton/ha/year, more than the Tolerable Soil Loss (TSL) value of 21,52 ton/ha/year. Therefore, restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability.

The plant diversity using shanon index and the farmer income level were investigated in this study. This information is very important to contribute some improvement of agroforestry pattern related to the farmer welfare and the ecological productivity in upperstream Minraleng Sub Watershed. Results show that the diversity index of mix public forest was higher than the other patterns, eventhough it has a lower contribution compared to paddyfield. Paddyfield and unirigated-land have a higher contribution to farmer income, but they have lower diversity indexes. In contrast, candlenut monoculture and mix garden have higher diversity indexes and lower contribution to farmer income. A plant diversification under candlenut stands and an economical plant intensification on mix garden were needed to increase the farmer income and the diversity of economic plants.
