Customary village is small group of people who still survive and consistently preserve the culture and belief of their ancestors. Local cultural values deserve to be promoted to the application of character education in school. The qualitative research understanding the life and local cultural values is carried out in the people of Kampung Adat Cirendeu in West Java. The local culture of the Kampung Adat Cirendeu people holds the principle of ngindung ka waktu and mibapa ka jaman which has the meaning of maintaining identity but still keeping abreast of the times. One of the local cultural values that still preserves until today is the culture of cassava-based food as a substitute for rice. This culture has been going on for a century and become an inspiration for the national food diversification program. One of the preservation efforts is through the example of their ancestors. Promotion and granting food culture values to the character education in schools involve various educational stakeholders (teachers, educators, governments, people, and customary peoples) that should give an example to the students. The most effective method is to form students with character and in the end they will be familiar with local food culture and does not depend on rice. Keywords: Character education, Kampung Adat Cirendeu, Exemplary. PENDIDIKAN KARAKTER NILAI-NILAI BUDAYA LOKAL MAKANAN DI MASYARAKAT KAMPUNG ADAT CIRENDEU JAWA BARAT MELALUI KETELADANANDesa adat adalah sekelompok kecil orang yang masih bertahan dan secara konsisten melestarikan budaya dan kepercayaan nenek moyang mereka.

BACKGROUND

There are previous experiences on the perception of patients with the use of telemedicine (TM). After break down caused by pandemic Covid19 crisis, mental health professionals in Spain should develop their work in a telematics way.

OBJECTIVE

Explore about the perceptions and interests of mental health professionals who have performed TM in the pandemic situation.

METHODS

An Ad-hoc questionary on the perception of the TM, the Work Satisfaction Questionnaire of Font Roja, and questions on patients satisfaction ere used. The data collected included 112 professionals of the Psychiatric Service who began to perform TM massively on March 16, following the alarm status declaration for ten weeks. More than 12.000 medical consultations were carried out on the phone.

RESULTS

High levels of satisfaction was detected among professional TM would function as a complement to the traditional system of face-to-face visits (n-112, f-109, 96.5%), only 9.7% (f-11) believed that the telematic system would completely replace face-toface visits. 60,8% did not consider this a monotonous work. The older the health workers were, the more satisfied they felt on their telephone follow-up consultation. The higher the previous experience the more satisfaction was showed. There are gender differences and women seems to be more adapted.

CONCLUSIONS

TM can be implemented without much effort, although the time, methods and resources used must be managed. Satisfaction among professionals is high, especially among those with more clinical experience. Patient satisfaction must be contrasted.

BACKGROUND

In addition to the obvious physical medical impact of COVID-19, the disease poses evident threats to people’s mental health, psychological safety, and well-being. Provision of support for these challenges is complicated by the high number of people requiring support and the need to maintain physical distancing. Text4Hope, a daily supportive SMS text messaging program, was launched in Canada to mitigate the negative mental health impacts of the pandemic among Canadians.

OBJECTIVE

This paper describes the changes in the stress, anxiety, and depression levels of subscribers to the Text4Hope program after 6 weeks of exposure to daily supportive SMS text messages.

METHODS

We used self-administered, empirically supported web-based questionnaires to assess the demographic and clinical characteristics of Text4Hope subscribers. Perceived stress, anxiety, and depression were measured with the 10-Item Perceived Stress Scale (PSS-10), the Generalized Anxiety Disorder–7 (GAD-7) scale, and the Patient Health Questionnaire–9 (PHQ-9) scale at baseline and sixth week time points. Moderate or high perceived stress, likely generalized anxiety disorder, and likely major depressive disorder were assessed using cutoff scores of ≥14 for the PSS-10, ≥10 for the GAD-7, and ≥10 for the PHQ-9, respectively. At 6 weeks into the program, 766 participants had completed the questionnaires at both time points.

RESULTS

At the 6-week time point, there were statistically significant reductions in mean scores on the PSS-10 and GAD-7 scales but not on the PHQ-9 scale. Effect sizes were small overall. There were statistically significant reductions in the prevalence rates of moderate or high stress and likely generalized anxiety disorder but not likely major depressive disorder for the group that completed both the baseline and 6-week assessments. The largest reductions in mean scores and prevalence rates were for anxiety (18.7% and 13.5%, respectively).

CONCLUSIONS

Text4Hope is a convenient, cost-effective, and accessible means of implementing a population-level psychological intervention. This service demonstrated significant reductions in anxiety and stress levels during the COVID-19 pandemic and could be used as a population-level mental health intervention during natural disasters and other emergencies.

Strategies to Reduce Rehospitalization in Patients with CKD and Kidney Failure
Authors: Doshi Simit , Wish Jay B.
Published: July 2020

Readmissions in patients with nondialysis-dependent CKD and kidney failure are common and are associated with significant morbidity, mortality, and economic consequences. In 2013, the Centers for Medicare and Medicaid Services implemented the Hospital Readmissions Reduction Program in an attempt to reduce high hospitalization-associated costs. Up to 50% of all readmissions are deemed avoidable and present an opportunity for intervention. We describe factors that are specific to the patient, the index hospitalization, and underlying conditions that help identify the “high-risk” patient. Early follow-up care, developing volume management strategies, optimizing nutrition, obtaining palliative care consultations for seriously ill patients during hospitalization and conducting goals-of-care discussions with them, instituting systematic advance care planning during outpatient visits to avoid unwanted hospitalizations and intensive treatment at the end of life, and developing protocols for patients with incident or prevalent cardiovascular conditions may help prevent avoidable readmissions in patients with kidney disease.

В работе представлены результаты проектирования четырех микросхем квадратурных модуляторов и демодуляторов, в которых реализована коррекция динамических параметров цифровым способом, что достигается регулировкой режимов работы отдельных функциональных блоков схемы. Разработаны опытные образцы квадратурных модуляторов и демодуляторов на основе SiGe технологического процесса и приведены результаты измерений. Показано, что при регулировке изменение фазового разбаланса может достигать значений до 5°, амплитудный разбаланс - до 2,8 дБ, а подавление паразитных составляющих может быть больше 50 дБ.

Проанализирована возможность использования кластерного анализа для оценки структурно-функциональной организации биологиче­ского объекта. Для количественного описания клеточных процессов выбрана фильтрующая (трабекулярная) ткань глаза при нестабилизи­рованной первичной открытоугольной глаукоме (ПОУГ) у пациентов, использующих макси­мально возможную гипотензивную терапию. Методом химического микроанализа на базе сканирующего электронного микроскопа (СЭМ) получены данные о распределении химических элементов в ткани. На основе глобального индекса Морана, описывающего степень пространственной группировки серы (IS) и фосфора (IP) на поверхности блока анализи­руемой ткани, предложен характеризующий клеточные процессы индекс потери целевой метаболической активности (IL). Установлена связь между IL и визуально наблюдаемым различием в организации структурных элементов трабекулярной ткани при ПОУГ. Прослежена корреляция между структурно-­функциональным статусом трабекулярной ткани по индексу IL и внутриглазным давлением (ВГД) на максимальной гипотензивной терапии.
ADOPTION OF VOLUNTARY GLOBAL GOVERNANCE INITIATIVES: EQUATOR PRINCIPLES AND BANKS IN NIGERIA
Authors: Oghojafor Ben Emukufia Akpoyomare , Aduloju Sunday Adekunle
Published: July 2020

Due to the growing level of dissatisfaction with the traditional models of governance established by the state, international governance initiatives have attracted more attention. This exploratory study is aimed at finding out the level of awareness and adoption of one such initiative, the Equator Principles (EPs), by banks in Nigeria. These principles were said to represent a good standard where environmental and social risks inherent in development projects can be identified, assessed and managed. The study was anchored on two theories: The club theory and the theory of institutional isomorphism. The survey data were gathered from 124 managers of the leading 10 deposit money banks in Nigeria. Data were analyzed using descriptive statistics presented in frequency tables and percentages. The findings show a high level of awareness of the EPs among the banks in Nigeria, but a low level of adoption. Although the study is limited by a small sample, it offers evidence that difficulties in measurability of benefits of adopting Equator Principles and lack of enforcements of sanctions for noncompliance seriously limit the number of financial institutions adopting the regime in Nigeria.

Abstract : Misuse of adding chemical drugs – BKO – into herbal medicines is often done by irresponsible people. The aim is to increase efficacy instantly, to attract consumer interest. BKO, which are often added to herbal medicine, are antalgin and dexamethasone. Antalgin content analysis was carried out quantitatively using the iodimetry titration method by conducting a preliminary test. The dexamethasone content analysis was carried out with qualitative and quantitative methods. The qualitative method was carried out using TLC. The quantitative method was carried out using the HPLC technique. The results obtained for the analysis of antalgin content of 10 samples were obtained two samples of herbal medicine containing antalgin, respectively 0,0749% and 0,1083%. Analysis of the dexamethasone content from 10 samples obtained 5 herbal samples containing dexamethasone respectively 0.0979%, 0.222%, 0.4521%, 0.5131% and 0.2809%. So based on these results, it is necessary to take action from the relevant institution regarding the discovery of the content of BKO in the herbal medicine on the market in Lombok.Abstrak : Penyalahgunaan penambahan bahan kimia obat (BKO) kedalam jamu sering sekali dilakukan oleh oknum yang tidak bertanggung jawab.
