Towards a holistic and intrinsic motivational concept of excellence in sport

( Athanasios Papaioannou ) 한국체육학회 2016 국제스포츠과학 학술대회 Vol.2016 No.1

In the birthplace of Olympic Games, ancient Greece, physical education and sport aimed at the development of excellence of any kind (arete). In Homer and other ancient Greek texts excellence of any kind in sport is defined as the best fit of all excellent qualities of a person (physical, mental, moral, social, spiritual). Aristotle particularly emphasized the intrinsic motivational concept of excellence and its connection with human flourishing. Modern research aligned with Aristotle’s perspective is found in Self-Determination Theory (SDT) and Nicholls’ Achievement Goals Theory (AGT). In line with Aristotle, (1) both theories adopt a teleological perspective emphasizing the intrinsic value of human action, (2) both theories connect human motivation with well-being and meaning in life, (3) both theories connect human flourishing with appropriate education; SDT emphasizes the process of internalization of external values and norms, while AGT emphasizes the cultivation of personal growth goals, (4) both theories connect motivation in achievement settings with moral behavior and human good. Two models stemming from these theories, Vallerand’s (1997) multidimensional model of motivation and Papaioannou’s (2007) multidimensional model of goal orientations, can be useful to test some of Aristotle’s assumptions. Examples of applications of Papaioannou’s (2007) model to cultivate personal growth goals in physical education are presented. Future research in motivation in sport should focus on the promotion of human good, which is the true spirit of Olympism. Suggestions for new lines of research in sport are made aiming at the development of a comprehensive model of excellence of any kind, in which the holistic and intrinsic motivational concept of excellence are perfectly connected with the promotion of human good.

Proclamation and Discipleship: Two Sides to Evangelistic Outreach (Matt 24:14 and 28:19-20)

As the Adventist church faces the 21st century with its manifold challenges, it also faces the seemingly impossible task of bringing the gospel to the whole world. Matt 24:14 and 28:19-20 have long served as beacons of insights and as the guiding texts on how to reach the world with the gospel. What is exactly envisaged in these two texts? This study analyses the key components of Matt 24:14 and Matt 28:19-20 and concludes that they represent not parallel texts but complementary. Together they offer a pathway to successful ministry in our challenging world.

Late Onset Disassembly of a Modular Neck-stem Component after Cementless Hip Replacement without Dislocation: A Case Report and Review of Literatures

( Ioannis Papaioannou ),( Thomas Repantis ),( Andreas Baikousis ),( Panagiotis Korovessis ) 대한고관절학회 2018 Hip and Pelvis Vol.30 No.3

Modular femoral prostheses are characterized by a second neck-stem junction. This modularity provides many clinical benefits including hip offset restoration, intraoperative leg length and anteversion adjustment. Although, this extra junction in modular femoral prostheses can contribute to catastrophic consequences like fracture, cold welding, corrosion and fretting of the modularity. However, only few complications related to the modularity itself have been reported in the literature. We report a unique case of neck-stem component dissociation without dislocation of the R-120PCTM Modular Stem (DJO Surgical). Our 71-year-old obese female patient underwent cementless hip replacement 5 years ago. Following radiographic confirmation of neck-stem dissociation open reduction was performed and wiring fixation was applied to secure the neck to the stem. After reduction and fixation, hip joint was stable, and our patient returned to her daily routine 2.5 months postoperatively. The last follow up was at 12 months after surgery with excellent radiographic and clinical evaluation.

Niobium (Nb) is present in Ni-based alloys and stainless steels used in nuclear reactors as structural materials. Nb-93 is a naturally occurring and stable isotope of niobium and Nb-94 (half-life = 20,000 years) is produced by neutron activation of Nb-93. Nb-94 can be present in waste streams from dismantling of nuclear power plants and treatment of the primary coolant circuit. Hence, the radioactive wastes containing active Nb-94 are disposed of in the repositories for low- and intermediate-level waste (LILW). Nb predominantly exhibits a pentavalent oxidation state (i.e., +V) within the stability field of water. Cementitious materials (concrete, mortar, and grout) are extensively utilized in LILW disposal systems as structural components and chemical agents for the stabilization of waste. Solubility defines the source term (i.e., upper concentration limit) in the repository system. However, the solubility behavior of Nb in cementitious systems at high pH remains ill-defined, and information available on the Nb solid phases controlling the solubility is scarce and often ambiguous. Sorption on cementbased materials is one of the main mechanisms controlling the retention of niobium(V) in a LILW repository, and distribution coefficients (Rd) are necessary to evaluate the retention capacity by sorption in the safety assessment of disposal systems. Available sorption data of Nb(V) on cement showed a large discrepancy in Rd, moreover, no sorption data is available for Nb(V) under conditions characterizing the first degradation stage of cement (young cement condition) at pH 13 – 13.5. In this context, the solubility of Nb was extensively investigated in porewater conditions representative of the cement degradation stage I, as well as in CaCl2-Ca(OH)2 systems. Special focus was given to the accurate characterization of the solubility-controlling solid niobium phases. We also studied the sorption of Nb(V) by hardened cement pastes (HCP) and calcium silicate hydrates (CSH, major hydrate of HCP). This work provides the results on Rd, sorption isotherm and sorption mechanisms of Nb(V). Besides, the impact of ISA (polyhydroxycarboxylic acid generated by the degradation of cellulose) on Nb(V) sorption and the dissolution of cement materials was investigated.

Purpose: Preclinical data increasingly support an impact of low-intensity extracorporeal shockwave therapy (Li-ESWT) on the bladder. We investigated the molecular effects of Li-ESWT on the bladder of a streptozotocin-induced diabetic rat model. Methods: Fifteen 8-week-old male Wistar rats were randomized into 3 groups: a control group (n=5), a group of diabetic rats without treatment (diabetes mellitus [DM], n=5) and a group of diabetic rats treated with Li-ESWT (DM-ESWT, n=5). A single intraperitoneal dose of streptozotocin (60 mg/kg) was used to induce diabetes. Twenty days after diabetes induction, each rat in the DM-ESWT group received 300 shockwaves with an energy flux density of 0.09 mJ/mm2. Sessions were repeated 3 times/week for 2 weeks, followed by a 2-week washout period. Total RNA from bladder tissue was extracted, cDNA was synthesized, and quantitative real-time polymerase chain reaction was performed to analyze the expression pattern of transient receptor potential vanilloid 1 (Trpv1), interleukin-1β (Il1b), and the muscarinic receptors M1, M2, and M3 (Chrm1, Chrm2, and Chrm3). Results: The expression of Trpv1, Il1b, and Chrm2 genes was significantly different between the 3 groups (P=0.002, P<0.0001, and P=0.011, respectively; 1-way analysis of variance). In the DM group, the expression of all genes was higher than in the control group, but statistical significance was observed only for Trpv1 and Il1b (P=0.002 and P<0.0001, respectively). Li-ESWT significantly reduced the expression of Il1b and Chrm2 (P=0.001 and P=0.011, respectively), whereas a nonsignificant tendency for reduced expression was noted for Trpv1 (P=0.069). Conclusions: The induction of diabetes was associated with increased expression of genes related to mechanosensation, inflammation/ ischemia, and contraction in the rat bladder. Li-ESWT reduced the expression of IL1b, Chrm2, and to a lesser extent Trpv1 toward the control levels, suggesting the therapeutic potential of this treatment modality for diabetic cystopathy.

A typical bile duct branching patterns represent one of the major causes of bile duct injury (BDI) during laparoscopic cholecystectomy (LC). The most common classified variations of bile duct branching, involve the right posterior sectoral duct (RPSD) and its joining with the right anterior or left hepatic duct. Variant bile duct anatomy can rarely be extremely complex and unclassified. This report describes an extremely rare case of an isolated injury to an aberrant right hepatic duct formed by the joining of ducts from segments V, VII, and VIII draining into the cystic duct (cysticohepatic duct) during LC, associated with an inferior RPSD opening to left hepatic duct. Detailed evaluation of both endoscopic and magnetic cholangiograms established the diagnosis. Bile duct injury was subsequently managed surgically by a demanding Roux-en-Y hepaticojejunostomy. This extremely rare case aims to serve as a useful reminder of the consistent inconsistency of biliary anatomy, alerting surgeons to beware of variant bile duct branching patterns during open or LC that constitute a dreadful pitfall for severe and life-threatening bile duct injuries.

Our objective was to evaluate the effectiveness of skin-stretching devices for closing defects on the extremities of dogs. Antebrachial skindefects were created on the limbs of 24 dogs randomly divided into three groups. Skin stretchers included staples and sutures passing throughthem (group A), sutures and hypodermic needles (group B), and Pavletic device (group C). Wounds on the left were further undermined inall groups. Tension and blood perfusion were assessed. After removing the stretchers on day 3, the defects were sutured and wound healingwas clinically scored. Histological variables evaluated were cellular infiltration, edema, collagen orientation, and thickness of epidermis. Significant differences in tension were found among groups (p < 0.0005) and between measurement times for undermined (p = 0.001) ornon-undermined (p < 0.0005) wounds. In contrast, blood perfusion values did not differ significantly. Clinical scores for group B seemedto be better than those for groups A and C, but differences were not significant. Primary wound closure using the Pavletic device was notfeasible. Νo significant differences in histological variables were found between groups. Skin stretching with staples or hypodermic needlesresulted in successful wound management with minor side effects on skin histology and circulation.

Characterization of a Neutron Beam Following Reconfiguration of the Neutron Radiography Reactor (NRAD) Core and Addition of New Fuel Elements

Craft, Aaron E.,Hilton, Bruce A.,Papaioannou, Glen C. Korean Nuclear Society 2016 Nuclear Engineering and Technology Vol.48 No.1

The neutron radiography reactor (NRAD) is a 250 kW Mark-II Training, Research, Isotopes, General Atomics (TRIGA) reactor at Idaho National Laboratory, Idaho Falls, ID, USA. The East Radiography Station (ERS) is one of two neutron beams at the NRAD used for neutron radiography, which sits beneath a large hot cell and is primarily used for neutron radiography of highly radioactive objects. Additional fuel elements were added to the NRAD core in 2013 to increase the excess reactivity of the reactor, and may have changed some characteristics of the neutron beamline. This report discusses characterization of the neutron beamline following the addition of fuel to the NRAD. This work includes determination of the facility category according to the American Society for Testing and Materials (ASTM) standards, and also uses an array of gold foils to determine the neutron beam flux and evaluate the neutron beam profile. The NRAD ERS neutron beam is a Category I neutron radiography facility, the highest possible quality level according to the ASTM. Gold foil activation experiments show that the average neutron flux with length-to-diameter ratio (L/D) = 125 is $5.96{\times}10^6n/cm^2/s$ with a $2{\sigma}$ standard error of $2.90{\times}10^5n/cm^2/s$. The neutron beam profile can be considered flat for qualitative neutron radiographic evaluation purposes. However, the neutron beam profile should be taken into account for quantitative evaluation.

Right and left common carotid arteries arising from the branchiocephalic, a rare variation of the aortic arch

Eleni Panagouli,Gregory Tsoucalas,Theodoros Papaioannou,Aliki Fiska,Dionysios Venieratos,Panagiotis Skandalakis 대한해부학회 2018 Anatomy & Cell Biology Vol.51 No.3

The aortic arch may present a plethora of anatomical variations, which my cause a cluster of complications in interventional procedures in surgery and angiography. We present a rare case of a common origin of both the common carotids arteries from the brachiocephalic trunk (anonymous artery), with the left common carotid artery emerging from the initial portion of it, forming a small common trunk. The great importance towards an excellent knowledge of the topographical aortic arch anatomy is stressed out.

Epistaxis in dental and maxillofacial practice: a comprehensive review

George Psillas,Grigorios Georgios Dimas,Despoina Papaioannou,Christos Savopoulos,Jiannis Constantinidis 대한구강악안면외과학회 2022 대한구강악안면외과학회지 Vol.48 No.1

The lifetime incidence of epistaxis in dental and maxillofacial practice has been reported to be as high as 60% and can be caused by dental implant placement, Le Fort I osteotomy, intranasal supernumerary tooth, odontogenic tumors, blood disorders and maxillofacial trauma. Most epistaxis cases are minor and easily managed with direct compression on the nares for 10 minutes. For more significant or recurrent epistaxis, other techniques might include electrocautery, anterior or posterior nasal packing, or Foley catheter balloon. For patients with refractory epistaxis, cauterization of the sphe-nopalatine artery under endonasal endoscopy or embolization of the internal maxillary artery should be performed. Epistaxis control is required in pa-tients diagnosed with inherited or acquired bleeding disorders or with drug-induced coagulopathies during dental procedures. In these cases, hemostatic system adjustment and hemostasis achieved by local and adjunctive methods are required. Dentists and maxillofacial surgeons must be aware that the nasal cavity is a potential source of perioperative hemorrhage. Depending on the invasiveness of the dental intervention, preoperative involvement of the hematologist and cardiologist is usually necessary to reverse anticoagulation or to cease anticoagulant therapy.
