K.G.P.A.A. Mangkunagoro I Forest Park is the one and only forest park in Central Java. As area of protection, life support system, and biodiversity preservation, K.G.P.A.A. Mangkunagoro I Forest Park plays an important role for life, especially for people around the forest area. To ensure this function, the sustainability of forest functions is determined by the presence of vegetation in the forest area. The purpose of this study was to determine the diversity of species, biomass and carbon stock of bamboo in K.G.P.A.A. Mangkunagoro I Forest Park. The diversity of bamboo species was observed by exploration method with an inventory. Then, based on the inventory data obtained, one species of bamboo was selected based on its number of clumps to determine the biomass and carbon storage. In the present study, there were 20 species bamboo at K.G.P.A.A. Mangkunagoro I Forest Park namely Bambusa balcoa, B. balcoa var. Capensis, B. bambos, B. blumeana, B. multiplex-green hedge, B. multiplex-alphanse karr, B. oldhami, B. tuldoides, B. vulgaris vulgaris, B. vulgaris vitata, B. vulgaris wamin budha, Dendrocalmus asper, D. asper thai, D. asper black, D. hamiltoni, Guadua amplexifolia, G. agustifolia, Oxytenanthera abysinica, Phyllostacys aurea, dan P. nigra. Furthermore, D. asper (petung bamboo) was the most dominated bamboo species. The number of D. asper were 758 clumps/ha and 3,213 reeds/ha. The average D. asper biomass was 6.02 kg/reed. Thus, the estimated biomass per ha was 19.5 tonnes/ha. In addition, D. asper has the ability to store carbon of 9.1 tonnes/ha.

In the context of the adoption at the 16th Conference of the Parties in 2010 on the REDD+ mitigation mechanism, it is important to obtain reliable data on the spatiotemporal variation of forest carbon stocks and changes (called Emission Factor, EF). A re-occurring debate in estimating EF for REDD+ is the use of existing field measurement data. We provide an assessment of the use of commercial logging inventory data and ecological data to estimate a conservative EF (REDD+ phase 2) or to report on EF following IPCC Guidance and Guidelines (REDD+ phase 3). The data presented originate from five logging companies dispersed over Gabon, totalling 2,240 plots of 0.3 hectares.We distinguish three Forest Types (FTs) in the dataset based on floristic conditions. Estimated mean aboveground biomass (AGB) in the FTs ranges from 312 to 333 Mg ha−1. A 5% accuracy is reached with the number of plots put in place for the FTs and a low sampling uncertainty obtained (± 10 to 13 Mg ha−1). The data could be used to estimate a conservative EF in REDD+ phase 2 and only partially to report on EF following tier 2 requirements for a phase 3.

Protection forest becomes a forest area with the main function as protection of life support systems. The health condition of protected forests has a great influence on the environment of the ecosystem. It is important to assess the health of protected forests in view of their main function. Thus to determine the health condition of the forest, one indicator that can be used is tree biodiversity. Biodiversity is the richness of life found on earth. Assessment of biodiversity indicators is very necessary to do because it is sensitive to changes, ecological system indicators, spatial heterogeneity, temporal, and and the order in the food chain. This study aims to determine the diversity of tree species in protected forest areas managed by HKm Beringin Jaya as an indicator of forest health assessment. The study was conducted using the Forest Health Monitoring (FHM) method. The results showed that the final value of forest health status with indicators of biodiversity (tree species diversity) in the protected forest area managed by HKm Beringin Jaya was in the good category of 50% in cluster plots (2, 5 and 6) and bad by 50% on cluster plots (1, 3 and 4), thus showing that the protected forest area managed by HKm Beringin Jaya has a fairly healthy (stable) condition with a moderate category.

Oceans are the life support system for our planet and are vital to human health. It is said that half of the oxygen we breathe is generated by our oceans. However, ocean space is becoming more globalized over time. Hence, it is essential for countries to take up a more holistic approach to ending ocean exploitation on the one hand, and also to ensuring a healthy ocean future on the other. Today, maritime cooperation is key to the management of the global commons, and ocean governance is important in establishing maritime connectivity. This article is a qualitative analysis of how the Association of Southeast Asian Nations (ASEAN) will undertake such an initiative to promote diverse and collaborative ocean governance in Asia. The article will analyze whether ASEAN countries are ready to take up the great power game challenge, and simultaneously motivate each other to promote sustainable development of common ocean governance structures and principles in the region. Last but not the least, we will see how ASEAN (Way) will connect with global trends in order to realize its a vision of building a community conscious of its historical ties and cultural heritage to improve the overall ocean health in Southeast Asia.

Background. The current basic life support guidelines recommend two-minute shifts for providing chest compressions when two rescuers are performing cardiopulmonary resuscitation. However, various studies have found that rescuer fatigue can occur within one minute, coupled with a decay in the quality of chest compressions. Our aim was to compare chest compression quality metrics and rescuer fatigue between alternating rescuers in performing one- and two-minute chest compressions. Methods. This prospective randomized cross-over study was conducted at Songklanagarind Hospital, Hat Yai, Songkhla, Thailand. We enrolled sixth-year medical students and residents and randomly grouped them into pairs to perform 8 minutes of chest compression, utilizing both the one-minute and two-minute scenarios on a manikin. The primary end points were chest compression depth and rate. The secondary end points included rescuers’ fatigue, respiratory rate, and heart rate. Results. One hundred four participants were recruited. Compared with participants in the two-minute group, participants in the one-minute group had significantly higher mean (standard deviation, SD) compression depth (mm) (45.8 (7.2) vs. 44.5 (7.1), P=0.01) but there was no difference in the mean (SD) rate (compressions per min) (116.1 (12.5) vs. 117.8 (12.4), P=0.08), respectively. The rescuers in the one-minute group had significantly less fatigue (P<0.001) and change in respiratory rate (P<0.001), but there was no difference in the change of heart rate (P=0.59) between the two groups. Conclusion. There were a significantly higher compression depth and lower rescuer fatigue in the 1-minute chest compression group compared with the 2-minute group. This trial is registered with TCTR20170823001.

AbstractObjective:To evaluate three prototype versions of semi-quantitative end-tidal CO2 monitors with different alarm features during prehospital or inter-facility use.Methods:Subjects were 43 adult, non-pregnant patients requiring intubation, or who already were intubated and required transport. Teams at one AirEvac and seven Advanced Life Support (ALS) paramedic stations were trained in the use of the monitors. Team members at each station evaluated each model for eight days. Participants completed questionnaires following each use.Results:The monitors performed properly in all cases, but in one case, vomit in the airway adapter tube prevented obtaining a readout. The monitors aided management in 40 of 43 cases (93%); in one, the monitor reading was reported as variable (between 20 and 30 mmHg) although the teams knew the monitors were semi-quantitative; in another, the monitor was not required, but performed properly; and the third was the one in which vomit in the tube prevented a reading. In 26 of 43 cases (60.4%), the monitor was used to confirm endotracheal tube placement (there were no instances of incorrect placement). In all cases, the devices were used to monitor respiration and oxygen saturation. Alarms were audible in the environment, but only preferred in the AirEvac situation. The “breath beep” feature was useful, particularly in patients in whom chest movements during respiration were difficult to observe.Conclusions:“Breath beeps” were clearly audible and were a useful feature in all prehospital and transport environments, while audible alarms were desired only in the AirEvac situation. Semi-quantitative CO2 detection is valuable in the ALS/AirEvac environment, even for teams with high intubation success rates.

The Karimunjawa National Park as the only one marine protected area in Central Java, managed by zonation system has decreased natural resources in the form of decreasing mangrove forest area, coral cover, sea biota population such as clams and sea cucumbers. Conservation has been done by Karimunjawa National Park Authority through protection of life support system activities in order to protect the area from degradation. The objective of the research is to know the implementation of protection and security activities of Karimunjawa National Park Authority for the period of 2012 - 2016. The research was conducted by qualitative method, processing secondary data from Karimunjawa National Park Authority and interview with key informants. The results showed that protection and security activities in The Karimunjawa National Park were held with three activities: pre-emptive activities, preventive activities and repressive activities. Implementation of conservation policy through protection of life support system is influenced by factors of policy characteristic, resource factor and environmental policy factor. Implementation of conservation policy need support from various parties, not only Karimunjawa National Park Authority as the manager of the area, but also need participation of Jepara Regency, Central Java Provinces, communities, NGOs, researchers, developers and tourism actors to maintain and preserve existing biodiversity. Improving the quality of implementors through education and training activities, the availability of the state budget annually and the support of stakeholders is essential for conservation.

According to the forest resources inventory data for different periods and the latest estimation parameters of forest carbon reserves in China, the carbon reserves and carbon density of forest biomass in the Tibet Autonomous Region from 1999 to 2019 were estimated using the IPCC international carbon reserves estimation model. The results showed that, during the past 20 years, the forest area, forest stock, and biomass carbon storage in Tibet have been steadily increasing, with an average annual increase of 1.85×104 hm2, 0.033×107 m3, and 0.22×107 t, respectively. Influenced by geographical conditions and the natural environment, the forest area and biomass carbon storage gradually increased from the northwest to the southeast, particularly in Linzhi and Changdu, where there are many primitive forests, which serve as important carbon sinks in Tibet. In terms of the composition of tree species, coniferous forests are dominant in Tibet, particularly those containing Abies fabri, Picea asperata, and Pinus densata, which comprise approximately 45% of the total forest area in Tibet. The ecological location of Tibet has resulted in the area being dominated by shelter forest, comprising 68.76% of the total area, 64.72% of the total forest stock, and 66.34% of the total biomass carbon reserves. The biomass carbon storage was observed to first increase and then decrease with increasing forest age, which is primarily caused by tree growth characteristics. In over-mature forests, trees’ photosynthesis decreases along with their accumulation of organic matter, and the trees can die. In addition, this study also observed that the proportion of mature and over-mature forest in Tibet is excessively large, which is not conducive to the sustainable development of forestry in the region. This problem should be addressed in future management and utilization activities.

An overview of modern foreign capital studies is presented. Human, social, psychological capitals as independent areas of research are singled out and described. For the first time, the concept of the capital of individuality, complementing other types of capital, is being introduced and developed. The basic features of capital are revealed through the concepts of resources and potentials. Individual properties taken together are shown as distributed resources and potentials, on the one hand, the combined resources and potentials of the individuality taken together by its properties on the other. The perspective of a systematic study of the capital of individuality may be the appeal to the theory of integral individuality of V.S. Merlin and the concept of system integration of human individuality by B.A. Vyatkin and L.Y. Dorfman. An approach to empirical study of the capital of individuality is planned, taking into account the multi-level properties of integral individuality as resources and potentials that enable a person to achieve high results in various areas of life. The concept of the capital of individuality is introduced in order to complement the existing notions of individual differences with a view of them from the point of view of revealing the strengths of human possibilities for existence, life support, individual success.

The global landscape for higher education internationalization is changing dramatically. What one might call “the era of higher education internationalization” might either be finished or, at least, be on life support. In addition to nationalist-populist factors, issues of academic freedom, ethics, the role of English, shifting patterns in student mobility, and concerns about transnational education, are challenging the future of internationalization. The current criticism about the unlimited growth of teaching in English, recruitment of international students and development of branch campuses, is coming from two completely opposite sources. On the one hand, there is the nationalist–populist argument of anti-international and anti-immigration. More relevant is the concern about quality, academic freedom, and ethics in the higher education community itself.

Intergrated Forest for Conservation Education of Wan Abdul Rachman (IFCE WAR) Great Forest Park is a conservation forest zone which has natural area and cultivated area.  The natural area in Wan Abdul Rachman Great Forest Park consists of secondary forest, whereas the cultivated area consists of agroforestry with cacao plants and agroforestry with coffee plants. The different land use in both areas caused the difference in carbon sink specifically in litter and soil. The research was aimed to study the difference of litter and soil carbon stock in natural and cultivated area in IFCE WAR Great Forest Park.  The observation plots included in the current study was determined using purposive sampling method. The research was conducted in June until August 2015. Data was analyzed using analysis of variance and continued with honestly significant difference test. The results showed that there was no difference of litter carbon stock in cultivated area and natural area in IFCE WAR Great Forest Park, whereas the soil carbon stock in natural area was higher than that in cultivated area.
