Authors: Agostinelli Angela , Marcantoni Ilaria , Moretti Elisa , Sbrollini Agnese , Fioretti Sandro , Di Nardo Francesco , Burattini Laura 
Published: April 2017

Background:
Indirect fetal electrocardiography is preferable to direct fetal electrocardiography because of being noninvasive and is applicable also during the end of pregnancy, besides labor. Still, the former is strongly affected by noise so that even R-peak detection (which is essential for fetal heart-rate evaluations and subsequent processing procedures) is challenging. Some fetal studies have applied the Pan-Tompkins’ algorithm that, however, was originally designed for adult applications. Thus, this work evaluated the Pan-Tompkins’ algorithm suitability for fetal applications, and proposed fetal adjustments and optimizations to improve it.

Method:
Both Pan-Tompkins’ algorithm and its improved version were applied to the “Abdominal and Direct Fetal Electrocardiogram Database” and to the “Noninvasive Fetal Electrocardiography Database” of Physionet. R-peak detection accuracy was quantified by computation of positive-predictive value, sensitivity and F1 score.

Results:
When applied to “Abdominal and Direct Fetal Electrocardiogram Database”, the accuracy of the improved fetal Pan-Tompkins’ algorithm was significantly higher than the standard (positive-predictive value: 0.94 vs. 0.79; sensitivity: 0.95 vs. 0.80; F1 score: 0.94 vs. 0.79; P<0.05 in all cases) on indirect fetal electrocardiograms, whereas both methods performed similarly on direct fetal electrocardiograms (positive-predictive value, sensitivity and F1 score all close to 1). Improved fetal Pan-Tompkins’ algorithm was found to be superior to the standard also when applied to “Noninvasive Fetal Electrocardiography Database” (positive-predictive value: 0.68 vs. 0.55, P<0.05; sensitivity: 0.56 vs. 0.46, P=0.23; F1 score: 0.60 vs. 0.47, P=0.11).

Conclusion:
In indirect fetal electrocardiographic applications, improved fetal Pan-Tompkins’ algorithm is to be preferred over the standard, since it provides higher R-peak detection accuracy for heart-rate evaluations and subsequent processing.
Study on Wellbore Stability of Shallow Sediments in Deepwater Drilling
Authors: Zhang Jun , Ai Chi , Zeng Bo , Li Yuwei , Zeng Jia 
Published: April 2017

Background:
The deepwater shallow formation has low fracture pressure and narrow safe window of mud density, which results in a high risk of wellbore instability in this kind of formation.

Objective:
Without considering the plastic state of shallow formation around the borehole or the influence of in-situ stress difference on wellbore stability, the prediction accuracy of the traditional wellbore stability analysis models are relatively low. This paper can provide a reliable method to accurately predict the safe window of drilling fluid density.

Method:
In this paper, the shallow formation around the borehole is divided into plastic zone and elastic zone considering it under non-uniform in-situ stress. The collapse pressure formula of shallow formation is derived by taking the shrinkage rate of the borehole as the instability criterion. The fracturing pressure calculation model of shallow sediment under non-uniform in-situ stress is derived by combining the theory of excess pore pressure and hydraulic fracturing.

Conclusion:
The calculated results indicate that the horizontal in-situ stress difference has a significant effect on the shape of the plastic zone, the shrinkage rate of borehole, collapse pressure and fracturing pressure. The calculated results are in good agreement with the field test results, and the prediction accuracy of this model is higher than that of other traditional models.

Published: April 2017

In view of the increasing number of hip joint replacement volume there remains the key issue of improving prosthesis survivorship which directly depends on the friction couple. Material and methods. The authors have analyzed five year outcomes of two bearing types (head and insert) used in hip replacement: ceramic-on-ceramic (CoC) in 324 patients and ceramic-on-polyethylene (CoP) in 300 patients. Totally 550 patients were operated in the period starting 2010 till 2014, including 74 patients underwent bilateral hip replacement. The authors divided patients based on gender and also into three age groups: 20-40, 41-60 and 61-80 years old. The largest group comprised 156 women aged 41-60 years (28.4%). Additional grouping of patients was made based on gender, age and bearing diameter.36 mm diameter bearing was characterized of the most frequent use. Functional outcomes were assessed by Harris Hip Score. Statistical analysis was made with Statistica 10 software. Statistical significant was observed at p0.05.Results.28 mm diameter bearing were rarely (19.5%) applied and mainly in women which is related to need for use of smaller acetabulum components and inability to implant a larger insert.36 mm diameter bearing were used most frequently, CoC articulation of36 mm was used in men in 34% of cases and in women – in 18.12% of cases.40 mm articulations were implanted in women two times less than in men which is related to a smaller diameter of acetabulum in women. Generally, CoC bearings were implanted more often in men which can be explained by a bigger social demand as well as a higher anti-luxation stability of large diameter bearings. Dislocations of implants occurred in 5 (0.91%) patients: in 4 patients with CoP bearingand in one patient with CoC articulation. Four revision procedures (0.64%) were made due to deep periprosthetic infection: two surgeries in each group. Harris Hip Score evaluation in CoC group demonstrated excellent and good outcomes in 99.2% of cases, and in CoP group – in 97.5% of cases.Conclusion. The authors observed no ceramic fractures or acoustic effects during 60 months follow up. It’s reasonable to increase CoC bearing diameter to achieve a better anti-luxation effect. CoC bearing selection should depend on patient’s activity and social demands but not only on the age. Based on study observations the authors forecast a higher survivorship of CoC couple within 15-20 years and expect to prove this conclusion in further studies.
Le « corps érotique » chez Michel Henry : le « trans-paraître » de la vie dans le vivant
Authors: Alvarado Cabellos Angel 
Published: April 2017

Cet article offre une discussion sur le statut du « corps érotique » chez Michel Henry dans le cadre d’une problématique d’ordre architectonique, en tant que celle-ci présente un « tournant » dans l’ensemble de sa pensée. D’une part, ce tournant nous conduit à la question du rapport entre la vie et le vivant, à partir d’une « duplicité de l’apparaître ». D’autre part, notre approche cherche à le comprendre à la lumière d’une problématique qui s’interroge sur la possibilité pour l’apparaître de la vie d’apparaître dans celui du monde, c’est-à-dire, pour emprunter un concept de G. Jean, de « trans-paraître ». L’architectonique henrienne — dont le phénomène de l’angoisse joue un rôle charnière — le comprend pourtant non pas comme le transparaître de la vie dans le monde, mais comme celui de la différence entre la vie et le monde dans le monde lui-même. Cette caractérisation « négative » doit être confrontée à la notion du « corps érotique », lequel semble nous fournir un accès « positif » au même concept.
BMI and All-Cause Mortality in Normoglycemia, Impaired Fasting Glucose, Newly Diagnosed Diabetes, and Prevalent Diabetes: A Cohort Study
Authors: Lee Eun Young , Lee Yong-ho , Yi Sang-Wook , Shin Soon-Ae , Yi Jee-Jeon 
Published: April 2017

OBJECTIVE
This study examined associations between BMI and mortality in individuals with normoglycemia, impaired fasting glucose (IFG), newly diagnosed diabetes, and prevalent diabetes and identified BMI ranges associated with the lowest mortality in each group.

RESEARCH DESIGN AND METHODS
A total of 12,815,006 adults were prospectively monitored until 2013. Diabetes status was defined as follows: normoglycemia (fasting glucose &lt;100 mg/dL), IFG (100–125 mg/dL), newly diagnosed diabetes (≥126 mg/dL), and prevalent diabetes (self-reported). BMI (kg/m2) was measured. Cox proportional hazards model hazard ratios were calculated after adjusting for confounders.

RESULTS
During a mean follow-up period of 10.5 years, 454,546 men and 239,877 women died. U-shaped associations were observed regardless of diabetes status, sex, age, and smoking history. Optimal BMI (kg/m2) for the lowest mortality by group was 23.5–27.9 (normoglycemia), 25–27.9 (IFG), 25–29.4 (newly diagnosed diabetes), and 26.5–29.4 (prevalent diabetes). Higher optimal BMI by worsening diabetes status was more prominent in younger ages, especially in women. The relationship between worsening diabetes status and higher mortality was stronger with lower BMI, especially at younger ages. Given the same BMI, people with prevalent diabetes had higher mortality compared with those with newly diagnosed diabetes, and this was more striking in women than men.

CONCLUSIONS
U-curve relationships existed regardless of diabetes status. Optimal BMI for lowest mortality became gradually higher with worsening diabetes for each sex and each age-group.
Microhardness and Roughness of Infiltrated White Spot Lesions Submitted to Different Challenges
Authors: Neres ÉY , Moda MD , Chiba EK , Briso ALF , Pessan JP , Fagundes TC 
Published: April 2017

SUMMARY
A white spot lesion is the first clinical sign of a caries lesion and represents mineral loss from the enamel subsurface. The purpose of this study was to evaluate the microhardness and surface roughness of white spot lesions after application of a resin infiltrant and subjection to different challenges. Caries-like lesions were induced in bovine enamel discs (n=50), and the specimens were randomly divided into five study groups (n=10): demineralized enamel (negative control, G1), infiltrated enamel (G2), infiltrated enamel submitted to brushing (G3), infiltrated enamel submitted to pH cycling (G4), and infiltrated enamel submitted to artificial aging (G5). Half of each enamel surface was used as its own positive control. Roughness data were analyzed using the Kruskal-Wallis test followed by the Dunn test. Results from microhardness were analyzed by two-way analysis of variance, followed by the Tukey test for multiple comparisons. The level of significance was set at 5%. Microhardness and roughness values obtained from the test side of the specimens were significantly lower compared with the sound enamel for all groups. Microhardness values obtained for G2, G3, and G5 were not significantly different. Values found for G1 were significantly lower compared with those for G2, G3, and G5. The lowest microhardness values were observed for G4, which was significantly different from the other groups. Surface roughness was not significantly different between G2 and G3. The resin infiltrant presented superiority over the unprotected white spot lesions, as they were more resistant to mechanical and aging challenges. However, resin infiltration was not able to reestablish the properties of sound enamel and was not resistant to a new cariogenic challenge.
Characterization of a Diamond Ground Y-TZP and Reversion of the Tetragonal to Monoclinic Transformation
Authors: Candido LM , Fais LMG , Ferreira EB , Antonio SG , Pinelli LAP 
Published: April 2017

SUMMARY

Purpose:
To characterize the surface of an yttria-stabilized zirconia (Y-TZP) ceramic after diamond grinding in terms of its crystalline phase, morphology, mean roughness (Ra), and wettability as well as to determine a thermal treatment to reverse the resulting tetragonal to monoclinic (t-m) transformation.

Methods and Materials:
Y-TZP specimens were distributed into different groups according to the actions (or no action) of grinding and irrigation. Grinding was accomplished using a diamond stone at a low speed. The samples were characterized by x-ray diffraction (XRD), scanning electron microscopy, goniometry, and profilometry. In situ high-temperature XRD was used to determine an annealing temperature to reverse the t-m transformation. Ra was submitted to the Kruskal-Wallis test, followed by the Dunn test (α=0.05). The volume fraction of the monoclinic phase and contact angle were submitted to one-way analysis of variance, followed by the Tukey test (α=0.05).

Results:
Monoclinic zirconia was observed on the surface of samples after dry and wet grinding with a diamond stone. The volume fraction of the monoclinic phase was smaller on the dry ground samples (3.6%±0.3%) than on the wet ground samples (5.6%±0.3%). High-temperature XRD showed reversion of the t-m phase transformation, which started at 700°C and completed at 800°C in a conventional oven.

Conclusions:
Grinding with a diamond stone partially transformed the crystalline phase on the surface of a Y-TZP ceramic from tetragonal to monoclinic zirconia while simultaneously increasing the surface roughness and wettability. The t-m transformation could be reversed by heat treatment at 800°C or 900°C for 60 minutes or 1000°C for 30 minutes.
Sudden Death Due to Asphyxia by Primary Tracheal Small Cell Carcinoma
Authors: Maskovyak Amanda , Felo Joseph 
Published: April 2017

Sudden natural asphyxial death in adults due to airway obstruction is an unusual cause of death. A variety of etiologies can cause airway obstruction, including benign or malignant tumors and soft tissue swelling from asthma, infections, or anaphylaxis. Malignant tracheal neoplasms are exceedingly rare with a reported incidence of approximately 2/1 000 000 and the small cell carcinoma subtype accounts for <10% of these tumors. We present a case of a 55-year-old female smoker who was found dead at home. At autopsy an obstructing lesion of the proximal trachea was identified that showed the characteristic cytomorphology of small cell carcinoma. No primary pulmonary lesions were identified. The cause of death was determined to be obstruction of the trachea by small cell carcinoma and the manner, natural.
Morbid Obesity is Not a Risk Factor for the Development of Clinically Significant Coronary Artery Atherosclerosis
Authors: Snyder Vivian S. , Curry Chelsea R. , Lew Emma O. , Matshes Evan W. 
Published: April 2017

Morbid obesity represents a significant health problem to a large and growing segment of the industrialized world. The cardiovascular complications are numerous and include systemic and pulmonary hypertension, obesity cardiomyopathy, heart failure, left ventricular dilatation and hypertrophy, arrhythmias, and sudden cardiac death. Morbidly obese (MO) individuals who die suddenly and unexpectedly may not have significant coronary artery atherosclerosis or acutely lethal natural diseases at autopsy. In this way, forensic pathologists may be challenged to understand the mechanism of sudden death when the major anatomic finding is often limited to cardiomegaly with or without chamber dilatation and wall thickening. The death investigation files for a large metropolitan medical examiner department were the source of data in this case-control retrospective study. A total of 3863 cases met inclusion criteria. The following data were obtained: sex, age, cause of death, manner of death, weight in pounds, height in inches, body mass index, heart weight in grams, and coronary artery atherosclerosis (CAA) severity. A population of MO decedents (N = 1290) was identified, and sex- and age-matched case controls of non-obese decedents (N = 2573) were selected. The degree of CAA was recorded for all major vascular territories in both MO decedents and control cases, and there was no statistically significant difference in CAA between decedents in the MO group and the control group. These data illustrate that obesity is not a significant independent risk factor for CAA.

Tulisan ini bertujuan memaparkan korelasi antara produksi seni sastra, seni teate, dan film serta menjelaskan keterkaitan yang erat antara urbanisasi, industrialisasi, dan urbanisme dengan perkembangan iptek dan seni, termasuk seni sastra, seni drama/teater, dan seni film/sinetron. Seirama dengan dinamika proses globalisasi di segala bidang, termasuk budaya dan seni, fenomena tersebut akan berdampak pada proses akulturasi lintas/silang budaya, perge- seran dan atau perubahan tata nilai dan identitas budaya bangsa. Akankah muncul identitas bu- daya ’baru’ (sebut yang khas ’urban’) dengan cara mengesampingkan atau membuang jauh-jauh identitas budaya ’lama’ (sebut tradisional) yang dianggap sudah ketinggalan zaman? Bagaimana sepantasnya ’masyarakat sastra, teater, dan film’ menyikapi fenomena-fenomena tersebut secara kritis, realistis, dinamis, dan arif? Serial Sinetron Film “Intan” dalam makalah ini diambil seba- gai studi kasus karena rating-nya yang relatif konstan tertinggi jika dibandingkan dengan serial sinetron film lainnya di media yang sama dalam kurun waktu yang sama.

Abstract:
This paper is aimed to describe correlation between literary, theater, and film art production and explain the strong interrelatedness between urbanization, industrialization, and urbanism by the development of science technology and art, including literary art, drama/theater art, and film/sinetron art. Along with the dynamic of globalization process in all aspects, including culture and art (literary, theater, and film art in this case), the phenomena will have influences to cross/inter-cultural acculturation process, shift and/or change in a nation’s cultural identity and values. Will a ‘new’ (call it urban) cultural identity emerge by putting aside or getting rid of the ‘old’ cultural identity (call it traditional) which is regarded as old fashion? How should a ‘literary, theater, and film community’ behave critically, realistically, and dynamically, and wisely to the phenomena?

Konstruksi Politik Tubuh dalam Teks Sastra Poskolonial
Authors: Taufiq Akhmad 
Published: April 2017

Tulisan ini mendiskusikan fenomena konstruksi politik tubuh dalam teks sastra poskolonial. Tubuh dalam perspektif poskolonial adalah domain yang dikonstruksi sedemikian rupa untuk menghasilkan efek ideologi, politik, ekonomi, bahkan kultural. Sehubungan dengan konteks tersebut, tubuh bukanlah domain yang kosong. Tubuh tersebut memiliki beberapa kemungkinan untuk diinterpretasikan dalam berbagai perspektif; dalam perspektif politik tubuh, tubuh itu sendiri sering dipolitisasi, dikomodifikasi, dan menerima ambiguitas psikologis sebagai subjek; dan sebagai tubuh yang terkolonisasi itu sangat menderita. Teks sastra poskolonial dalam perkembangan sastra Indonesia dalam hal ini, salah satu kajiannya sering mendeskripsikan realitas politik tubuh.

Abstract:
This writing discusses about the fenomenon of the construction of body in postcolonial literary text. Body in the postcolonial literature perspective is a constructed domain with goals to get ideologic, politics, economic, and cultural effect. Relates to the context, body is not only an empty domain. The body is very possible to be interpreted in some perspectives; politics of body, the body it self is often politicized, comodified, and got psycological ambiguity as a subject and colonized body that also very suffering. The postcolonial literature text in the Indonesian literature development often describes the reality of the politics of body.

Introducing Helaehili, an Oral Poetry From Sentani, Papua
Authors: Modouw Wigati Yektiningtyas 
Published: April 2017

This paper is partially taken from my research on a Sentani oral poetry, helaehili that is sung in mourning occasions or funerals. It is also usually known as a song of lamentation. The research was conducted in Sentani, Papua, for almost four years (2004-2008). The data were taken directly from the field through recording. The data were then transcribed, translated into English and analyzed. Through the research, it is found that helaehili is rarely heard. Not many people, especially those who live near Jayapura city and young generation, know the song. It is predicted that helaehili will extinct in some years. The research finds the composition, formula, theme, and notation of helaehili.

Abstrak:
Tulisan ini merupakan sebagian dari penelitian saya tentang lantunan lisan Sentani, helaehili yang biasanya dilantunkan ketika ada kedukaan atau penguburan jenazah. Lantunan ini juga disebut sebagai ratapan. Penelitian dilakukan di wilayah Sentani, Papua selama hampir empat tahun, pada 2004-2008. Data diambil melalui rekaman langsung dari para pelantun di lapangan, kemudian ditranskripsi, diterjemahkan ke dalam bahasa Indonesia, dan dianalisis. Mela- lui penelitian ini ditemukan bahwa helaehili sudah jarang dilantunkan. Tidak banyak orang, terutama yang tinggal dekat kota Jayapura dan para generasi muda yang mengenalinya. Dengan demikian, diprediksi bahwa lantunan ini akan hilang pada beberapa tahun ke depan. Penelitan ini menemukan komposisi, formula, tema, dan notasi mayor helaehili.
