Published: June 2018

The aims of present study was to test the theoritical linking model of authentic leadership with personal identification, social identification, trust to leader, and organizational commitment in higher education institution. The quantitative methodology used in this study incorporates cross-sectional survey method. Analysis was conducted on the sample of 150 academic and administrative staff from one of private business school in Yogyakarta special region. The direct effect between variables analyzed using path analysis and mediating mechanism using procedure from Baron and Kenny (1986) and Sobel test. Results reveal positive and significant direct effect of authentic leadership to personal identification, social identification, trust to leader and organizational commitment. Folower’s personal identification mediate the effect of authentic leadership to follower’s trust and commitment. Follower’s trust to leader mediate the relationship between authentic leadership and follower’s commitment. Meanwhile, social identification does not mediate the effect of authentic leadership to follower’s commitment and trust to leader. Implication for management theory and practice are discussed.
Gender disparities in screening for congenital hypothyroidism using thyroxine as a primary screen
Authors: DeMartino Lenore , McMahon Rebecca , Caggana Michele , Tavakoli Norma P 
Published: June 2018

Objective
Newborn screening for congenital hypothyroidism (CH) is based on testing for the markers thyroxine (T4) and/or thyroid-stimulating hormone (TSH). Diagnosis of CH is complicated because many factors affect the levels of these hormones including infant birth weight, prematurity and age at specimen collection. We investigated whether the sex of the newborn affected the levels of T4 and TSH and consequently the outcome of newborn screening.

Design
In New York State, the Newborn Screening program initially tests all infants for T4 and any baby with a result in the lowest 10% is triaged for TSH screening. We analyzed data from 2008 to 2016 to determine mean and median T4 and TSH values and how these results correlate with the sex of infants who are reported as borderline, referred and confirmed with CH.

Methods
T4 and TSH concentrations in dried blood spots were measured using commercially available fluoroimmunoassays.

Results
From 2008 to 2016, of the 2.4 million specimens tested for thyroxine, 51.5% were from male and 48.5% were from female infants. Male infants constituted 60% of specimens triaged for TSH testing, 64.9% of repeat requests and 59.6% of referrals, but only 49% of confirmed CH cases. The mean and median T4 values were lower (a difference of approximately 0.8–1.1 μg/dL each year) and the median TSH values were higher in male compared to female infants.

Conclusions
Natural differences in thyroid hormone levels in male and female infants leads to male infants being disproportionately represented in the false-positive category.

Published: June 2018

AbstractCanine neuroaxonal dystrophy (NAD) is a recessive, degenerative neurological disease of young adult Rottweiler dogs (Canis lupus familiaris) characterized pathologically by axonal spheroids primarily targeting sensory axon terminals. A genome-wide association study of seven Rottweilers affected with NAD and 42 controls revealed a significantly associated region on canine chromosome 5 (CFA 5). Homozygosity within the associated region narrowed the critical interval to a 4.46 Mb haplotype (CFA5:11.28 Mb – 15.75 Mb; CanFam3.1) that associated with the phenotype. Whole-genome sequencing of two histopathologically confirmed canine NAD cases and 98 dogs unaffected with NAD revealed a homozygous missense mutation within the Vacuolar Protein Sorting 11 (VPS11) gene (g.14777774T &gt; C; p.H835R) that was associated with the phenotype. These findings present the opportunity for an antemortem test for confirming NAD in Rottweilers where the allele frequency was estimated at 2.3%. VPS11 mutations have been associated with a degenerative leukoencephalopathy in humans, and VSP11 should additionally be included as a candidate gene for unexplained cases of human NAD.
Tubular Excretory Canal Structure Depends on Intermediate Filaments EXC-2 and IFA-4 in Caenorhabditis elegans
Authors: Al-Hashimi Hikmat , Hall David H , Ackley Brian D , Lundquist Erik A , Buechner Matthew 
Published: June 2018

Abstract
The excretory canals of Caenorhabditis elegans are a model for understanding the maintenance of apical morphology in narrow single-celled tubes. Light and electron microscopy shows that mutants in exc-2 start to form canals normally, but these swell to develop large fluid-filled cysts that lack a complete terminal web at the apical surface, and accumulate filamentous material in the canal lumen. Here, whole-genome sequencing and gene rescue show that exc-2 encodes intermediate filament protein IFC-2. EXC-2/IFC-2 protein, fluorescently tagged via clustered regularly interspaced short palindromic repeats/Cas9, is located at the apical surface of the canals independently of other intermediate filament proteins. EXC-2 is also located in several other tissues, though the tagged isoforms are not seen in the larger intestinal tube. Tagged EXC-2 binds via pulldown to intermediate filament protein IFA-4, which is also shown to line the canal apical surface. Overexpression of either protein results in narrow but shortened canals. These results are consistent with a model whereby three intermediate filaments in the canals—EXC-2, IFA-4, and IFB-1—restrain swelling of narrow tubules in concert with actin filaments that guide the extension and direction of tubule outgrowth, while allowing the tube to bend as the animal moves.

Published: June 2018

BACKGROUND AND OBJECTIVES:
Children born extremely preterm are at risk for cognitive difficulties and disability. The relative prognostic value of neonatal brain MRI and cranial ultrasound (CUS) for school-age outcomes remains unclear. Our objectives were to relate near-term conventional brain MRI and early and late CUS to cognitive impairment and disability at 6 to 7 years among children born extremely preterm and assess prognostic value.

METHODS:
A prospective study of adverse early and late CUS and near-term conventional MRI findings to predict outcomes at 6 to 7 years including a full-scale IQ (FSIQ) &lt;70 and disability (FSIQ &lt;70, moderate-to-severe cerebral palsy, or severe vision or hearing impairment) in a subgroup of Surfactant Positive Airway Pressure and Pulse Oximetry Randomized Trial enrollees. Stepwise logistic regression evaluated associations of neuroimaging with outcomes, adjusting for perinatal-neonatal factors.

RESULTS:
A total of 386 children had follow-up. In unadjusted analyses, severity of white matter abnormality and cerebellar lesions on MRI and adverse CUS findings were associated with outcomes. In full regression models, both adverse late CUS findings (odds ratio [OR] 27.9; 95% confidence interval [CI] 6.0–129) and significant cerebellar lesions on MRI (OR 2.71; 95% CI 1.1–6.7) remained associated with disability, but only adverse late CUS findings (OR 20.1; 95% CI 3.6–111) were associated with FSIQ &lt;70. Predictive accuracy of stepwise models was not substantially improved with the addition of neuroimaging.

CONCLUSIONS:
Severe but rare adverse late CUS findings were most strongly associated with cognitive impairment and disability at school age, and significant cerebellar lesions on MRI were associated with disability. Near-term conventional MRI did not substantively enhance prediction of severe early school-age outcomes.

Published: June 2018

Background
Chronic alcohol ingestion-induced kidney structure and function alterations are very well known, but the precise underlying molecular mediators involved in ethanol-induced kidney abnormalities remain elusive. The aim of this study was to investigate the effect of chronic ethanol exposure on matrix metalloproteinase 2, 9 (MMP), glomerular filtration barrier proteins (nephrin and podocin), as well as vascular endothelial growth factor receptor 1, 2 (VEGFRs) isoforms gene expression in the kidney of rats.

Methods
Sixteen male Wistar rats with an initial body weight of 220 ± 10 g were divided into the following two groups: (1) control and (2) ethanol (4.5 g/kg BW).

Results
After 6 weeks of treatment, the results revealed a significant increase in isoforms VEGFR1 and VEGFR2 of VEGFR gene expression, significant increases of MMP2 and MMP9 activities, as well as significant decrease of nephrin and podocin gene expressions in the ethanol group, compared with that in the control group.

Conclusion
These findings indicate that ethanol-induced kidney abnormalities may be in part associated with alteration in expressions of VEGFRs, nephrin, and podocin and in increasing activities of MMP2 and MMP9 as key molecular mediators in the kidney function.

TN-82 — a relational database management system
Authors: Tho Do Xuan , Thanh Dinh Thi Ngoc 
Published: June 2018

Using the relational approach of database systems, the TN-82 has been developed and implemented on a minicomputer. The system consists of four subsystems which have relatively independent functions. These subsystems can be modified and extended, if it is necessary to obtain a new one, which adapts another practical problem with few costs. The system TN-82 is a structured system and controlled by hierarchical principles. The method based on module programming has been used. Data independence, data consistency, some problems of data security and integrity are guaranteed. Many blocks of information stored in the system can be unified. The system has been constructed in such a way that the redundant information is eliminated as much as possible. With a simple but powerful Vietnamese query manguage, a user is able to easily formulate his non-procedural queries. The query processing is based on implementing in the system of almost operations of relational algebra (such as selection, projection, join, union, difference, intersection). Some problems of query optimizing are resolved and applied in this system, such as analyzing and choosing the orders of executed operations, selecting access paths,… The system TN-82 can be easily realized on the other more powerful computers.

Some computational problems related to normal forms
Authors: Thi Vũ Đức 
Published: June 2018

In the relational database theory the most desirable normal form is the Boyce-Codd normal form (BCNF). This paper investigates some computational problems concerning BCNF relation scheme and BCNF relations. We give an effective algorithm finding a BCNF relation r such that r represents a given BCNF relation scheme s (i.e., Kr=Ks, where Kr and Ks are sets of all minimal keys of r and s). This paper also gives an effective algorithm which from a given BCNF relation finds a BCNF relation scheme such that Kr=Ks. Based on these algorithms we prove that the time complexity of the problem that finds a BCNF relation r representing a given BCNF relation scheme s is exponential in the size of s and conversely, the complexity of finding a BCNF relation scheme s from a given BCNF relation r such that r represents s also is exponential in the number of attributes. We give a new characterization of the relations and the relation scheme that are uniquely determined by their minimal keys. It is known that these relations and the relation schemes are in the BCNF class. From this characterization we give a polynomial time algorithm deciding whether an arbitrary relation is uniquely determined by its set of all minimal keys. In the rest if this paper some new bounds of the size of minimal Armstrong relations for BCNF relation scheme are given. We show that given a Sperner system K and BCNF relation scheme s a set of minimal keys of which is K, the number of antikeys (maximal nonkeys) of K is polynomial in the number of attributes iff so is the size of minimal Armstrong relation of s.

From a convergence to a reasoning with internal-valued probability
Authors: Diệu Phan Đình , Quế Trần Đình 
Published: June 2018

Combining a deduction in a knowledge base of external uncertainty whose semantics has been proposed by N.J.Nilsson with a deduction coming from a convergence of a sequence of operators in a knowledge base of internal uncertainty, we propose a method of reasoning in a knowledge base of the both types of uncertainty. Let B an S be such a knowledge base and a goal sentence, respectively. The interval of truth probabilities of S derived from B can be found by the proposed method.

Published: June 2018

As pointed out in [1], Multivalued dependencies (MVD) depend on the context in which they are defined and thus are very hard to visualize. In this paper, continuing the study in [1], we give some results which may provide some more insight regarding the existence of possible MVDs in the relation schemes provided all their FDs are known in advance. Throughout this paper, we assume that the reader is familiar with the basic concepts of the relational database [2,3]. Tóm tắt. Như đã chi rõ trong [1], các phụ thuộc đa trị (MVD) phụ thuộc vào ngữ cảnh trong đó chúng đươc xác đinh và do đó rất khó phát hiện.

Authors: Ban Doan Van , Hung Dang Van 
Published: June 2018

It is well know in [2, 3] that in general processes in Petri Nets are not recoverable from firing sequences. However, firing sequences in Petri Nets say something about concurrency. The paper presents a way to define concurrency form firing sequences of nets. It turns out that the information of concurrency in a firing sequence characterise all its processes.
