The convex function is one of the topics in mathematics that is closely related to the theory of inequality. Furthermore, the definition of convex function has an extension which is the first and second kind of s convex function, for fixed s elemen 0,1 . Convex function has a relation to the Hermite Hadamard Fejerinequality, which is an integral inequality involving a convex function. Further development of these inequalities involves the s convex function and also through the concept of fractional integral. In this study, we discuss theHermite Hadamard Fej r type inequality that applies to the second kind of s convex function via the Riemann Liouville fractional integral. From these results, the relationship between these inequalities with the same type of inequality for convex function, are obtained."

ABSTRACTBackground: Chronic hyperglycemia in patients with type 1 diabetes mellitus (T1DM) is associated with long term functional impairment and damage of several parts of the body, such as eyes, kidneys, nerves, heart, and capillary blood vessels. Among all systems, disorder of pulmonary function due to hyperglycemia is often neglected by physicians. Pulmonary function test could determine whether the lung impairment is obstructive, restrictive, or mixed. Pulmonary function test using spirometry could not be applied to children below 7 or 8 years old because they are not capable to do the test. Until now, research about the effect of T1DM to pulmonary function has never been done in Indonesia.Objective: To obtain pulmonary function test profile in type 1 diabetes mellitus patients aged 8 to 18 years old.Methods: This cross sectional study took place at Endocrinology and Respirology Outpatient Department of Cipto Mangunkusumo Hospital (RSCM) and Prodia Laboratory Service in Salemba in January 2015.

"Maen pukulan merupakan budaya Betawi yang mengandung unsur olah raga, budaya, spiritual, dan bela diri. Ia merupakan warisan yang hidup pada masyarakat Betawi serta Jakarta dan sekitarnya. Satu aliran maen pukulan yang relatif lama, eksis, dan populer pada masa kini ialah Beksi Tradisional H. Hasbullah. Tujuan penelitian ini ialah mengkaji penggunaan memori kolektif pada perguruan maen pukulan Beksi Tradisional H. Hasbullah sebagai bagian dari budaya masyarakat Betawi dilihat dari sistem pewarisan dan pengelolaan perguruan pada masa kini. Pada perguruan tersebut, memori yang terpelihara terbagi menjadi memori individu yang teraplikasi pada guru maen pukul dan memori kolektif yang terdapat pada komunitas. Menggunakan tiga teori mengenai memori kolektif oleh Rubin, Bernecker, dan Halbwachs ditemukan bahwa maen pukulan Beksi Tradisional H. Hasbullah berkembang menggunakan memori kolektif para guru, murid, serta masyarakat yang menanggap pertunjukan Beksi. Ditemukan pula memori individu guru membentuk pola pewarisan yang ia pilih bagi muridnya serta tipe pengelolaan yang digunakan dalam kepengurusan perguruan. Memori kolektif berperan pada pertunjukan yang mengandung Beksi di dalamnya. Memori menjadi panduan ketika terjadi perbedaan walau di sisi lain, memori yang tereduksi menyebabkan terjadinya pengerucutan pakem pertunjukan. Penelitian ini menunjukkan pentingnya peran memori kolektif untuk eksistensi dan perkembangan maen pukulan di masa depan.

Maen pukulan is a part of Betawinese tradition that contains sport, cultural, spiritual, and martial arts elements. It is a living heritage among Betawinese community and is found in Jakarta and its surrounding areas. A relatively old school of maen pukulan which still exists and popular today is the H. Hasbullah’s Traditional Beksi. This research aims to investigate the use of collective memory in the current Maen Pukulan Beksi Traditional H.Hasbullah schools as a part of Betawinese culture related to its cultural inheritance pattern and management. At the maen pukulan schools, there are two types of preserved memory. The first is individual memory which is applied by the maen pukulan gurus and the second is collective memory which is found among the community. Using three theories about collective memory by Rubin, Bernecker, and Halbwachs, it is found that the traditional maen pukulan Beksi of H. Hasbullah has developed through the collective memory of the gurus, students, and the publics who perceive the Beksi performance. It is also found that individual memory of the gurus forms an inheritance pattern which they choose for their students and the type of management use at the maen pukulan school organisation. Collective memory has its role in the performance that contains Beksi in it. The memory, on the one hand, becomes their guide when there is a dispute about Beksi. On the other hand, reduced memory has caused some changes and reduction, along with the continuity in the maen pukulan Beksi performance. This research shows the important role of collective memory in maintaining the existence and development of maen pukulan in the future."

Background: Premature ventricular complexes (PVC) was associated with a risk of decreased ventricular function and heart failure, and increased long-term mortality. Low circadian variation is one of the predictors of PVC-induced cardiomyopathy. Independent-type-PVC (I-PVC) is a form of PVC with a low distribution of circadian variation. However, not all I-PVC show low circadian variation. No studies have been performed to examine differences in intrinsic systolic function of left ventricle (LV) using global longitudinal strain (GLS) in independent versus non-independent idiopathic PVC.

Objective: To determine the relationship between I-PVC and intrinsic systolic function of LV using speckle tracking echocardiography in patients without structural heart disease.

Methods: A cross-sectional study was conducted using data from patients with idiopathic ventricular arrhythmias collected at RSPJD Harapan Kita Jakarta in February 2021-May 2021. Evaluation of idiopathic PVC was carried out using a 12-lead ECG, 24-hour Holter monitoring. Basic echocardiography was performed then LV intrinsic systolic function was assessed using speckle tracking echocardiography with global longitudinal study (GLS).

Results: Of the 67 patients with idiopathic PVC included in the study, 27 (40.2%) patients included in independent PVC group and 40 (59.8%) patients in non-independent PVC group. A total of 31 (46.3%) patients had LV systolic dysfunction on GLS examination (less than -18). Independent-type-PVC (OR 5.3; 95% CI 1.10-33.29; p = 0.038), PVC burden of 9% (OR 16; 95% CI 1.58-163.61; p = 0.019), male gender (OR 6.58; 95% CI 0.80-0.99; p = 0.029), and non-sustained VT episodes (OR 13.88; 95% CI 1.77-108.53; p = 0.012) was significantly associated with a decrease in LV intrinsic systolic function.

Conclusion: Independent-type-PVC was associated with decreased in LV intrinsic systolic function assessed by speckle tracking echocardiography. Evaluation of the type of idiopathic PVC needs to be considered since it is related with patient's prognosis in clinical practice."
