(Directed by Professor In Hee Chung, M.D.)
The arthrodesis of the hip is the only certain method for eliminating pain and
providing sability in young and middle aged adults. The first used arthrodesis in
old congenital dislocation was reported by Heusmer, Lampugnani, and Alert as early
as 1885 according to Nove-Joesearand.
The various papers published on this operation appear to be concerned mainly with
surgical methods and the frequency of bone healing, rather than with loss of
function and its causes.
The purpose of this study is to evaluate function of the arthrodesed hip
especially the relationship between position of the hip and its daily use.
The author studied arthrodesis of the hip clinically in 89 cases of arthrodesed
patients, admitted to the Orthopedic Department of Severance Hospital during the 14
years from June 1957 until May 1970. The author also studied 40 cases which
confirmed sound bony ankylosis of the hip by X-ray examination. The follow-up
included a careful inquiry into the patients ability to use the fixed hip in
various functions of daily life.
The results are as follows:
1. The average age of the patients at the time of operation was 16.9 years and
tuberculosis of the hip was the most common cause 83(93%) of arthrodesis.
2. The most common type of operation in this series was intraarticular
arthrodesis 67(75.3%), and the fusion rate was relatively good in intra &
extraarticular arthrodesis 20(85.5%).
3. The average length of follow-up was 16.2 years. The average position of the
arthrodesed hip was 37.7 degrees of flexion, 9.1 degrees of abduction and neutral
rotation. Actual shortening of the leg averaged 3.8cm.
4. The gait was poor in the group which had 5cm shortening of the leg and was in
43 degrees of flexion for the arthrodesed hip.
5. The ability to sit and defecate in the ordinary toilet was satisfactory when
there was 39 degrees of flexion or more for the arthrodesed hip.
6. 10 patients(25%) had back pain and 12 patients(30%) had mild scoliosis.
Average Ferguson angle was 34.3 degrees and the Line of Weight Thrust showed over
40 degrees of flexion.
7. The ideal hip position of arthrodiesis in Koreans was assumed to be under 40
degrees of flexion, some degrees of abduction and no rotation.

Chirality in Dendritic Architectures
No full textA review with 38 refs. At first glance the topic of chiral dendrimers seems to be a contradiction in terms. However, recent studies reveal that both the building blocks of the dendrimer and the overall dendritic architecture can be chiral and that chirality can be introduced at various levels. The expression of optical activity in these enantiomerically pure dendrimers as a result of conformational (dis)order has proven to be of special interest. We present the different approaches to introducing chirality in dendritic architectures, organized through their possible impact in fields such as biocompatibility, catalysis, mol. recognition, and surface chem. Also, the relation between mol. chirality of core or building block and the macroscopic chirality of dendritic objects is discusse

No full textHWI Group heeft een websiteframework waar meerdere sites op draaien. Doordat er vele jaren door verschillende personen geschreven is aan de code is het lastig dit framework te onderhouden en verder uit te breiden. Ook is het niet rendabel om een nieuw framework uit het niets te ontwerpen. Daarom moet het huidige systeem geanalyseerd worden en aan de hand van deze analyse moet een nieuwe systeem ontworpen worden. Het feit dat de database vrijwel niet aangepast mag worden, dat het framework meerdere sites moet ondersteunen en dat het parallel met de legacy code gedraaid kan worden vormen restricties voor dit herontwerp. Het eerste onderzoek aan het systeem was een requirements analyse. Gedurende deze fase zijn de requirements van het gehele systeem op een rij gezet. Deze analyse leverde meer dan 300 requirements op. Deze werden teruggebracht tot 16 algemene use cases. Dezelfde abstrahering is ook in het prototype naar voren gekomen, waardoor de code eenvoudiger werd. Vervolgens is de architectuur ontworpen. Deze maakt gebruik van bestaande design patterns, dit om te voorkomen dat het wiel opnieuw uitgevonden wordt. Er zijn twee patterns waar de architectuur zwaar op leunt: dependency injection en het observer pattern. Het voordeel van de eerste is het verminderen van terugkerende code. De tweede pattern houdt in dat objecten zich inschrijven om geactiveerd te worden als een bepaald event plaatsvindt. Dit pattern wordt toegepast wegens de mogelijkheden om het systeem uit te kunnen breiden zonder dat er extra code afhankelijkheden voorkomen. Symfony2 en Doctrine2 vormen een zeer goede basis om een complex systeem, zoals het systeem van HWI Group, te implementeren. Meer over deze basis volgt in de sectie 'Implementatie'. Tijdens het verzamelen van de user requirements was er het vermoeden dat heel veel aspecten van het systeem hetzelfde waren. Gedurende de implementatie bleek dit vermoeden gegrond te zijn. Abstractie speelde een zeer grote rol om de grootte van de codebase naar beneden te trekken. In de meeste gevallen moet een item of een overzicht van items getoond worden. Om hierbij te helpen ontstonden de Item- en OverviewManager. Meer over de abstractie is te vinden in de sectie 'Implementatie'. Het was erg lastig om van tevoren een goede planning te maken. Een nieuw framework brengt namelijk altijd een leercurve met zich mee, en de tijdsduur van het begrijpen van het huidige systeem is ook erg lastig om van tevoren in te schatten. Daarom is er voor besloten om een soort van Agile werkwijze te hanteren. Dit houdt in dat er korte sprints waren en dat het systeem incrementeel werd uitgebreid. Er waren geen dagelijkse bijeenkomsten zoals gebruikelijk is voor een Agile werkwijze. Het voordeel van deze werkwijze is dat ongeacht hoe snel of traag de implementatie zou gaan, het prototype zou altijd werken. We geven HWI Group het advies om zich meer te richten op het documenteren van code. Een mooi moment om documentatie te typen is aan het eind van een sprint, we adviseren dus ook om dit altijd te doen. Verder adviseren we om code review uitgebreid toe te passen. Er moet dus altijd een tweede programmeur zijn die de code van een andere programmeur goedkeurt. In weinig tijd, met een goed team en goede documentatie voor de gebruikte tools is het gelukt om de afspraken aan het bedrijf na te leven. Het prototype biedt meertalige tekst, kan meerdere sites draaien en in parallel met de legacy code werken. Het prototype is dus geslaagd.Software TechnologyElectrical Engineering, Mathematics and Computer Scienc
Cryptochirality and dendrimers
No full textThe synthesis and characterization of the first enantiomerically pure cryptochiral dendrimer is presented. Enantiomerically pure S-solketal (I) was coupled with 3,5-bis(benzyloxy)benzyl bromide (II) and the ketal product was hydrolyzed under acidic conditions. The primary alc. in the product was selectively protected with TBDMSCl and the secondary alc. was etherified with benzyl bromide. Acid catalyzed deprotection of the TBDMS protecting group and Williamson coupling of the product yielded the chiral dendrimer III. The same reaction route from I was used to prep. the R enantiomer by changing the sequence of attachment in the synthesis. Both enantiomeric forms of III do not exhibit any optical activity in the 200-800 nm range and are therefore referred to as cryptochiral dendrimer
Exercise hyperthermia induces greater changes in gastrointestinal permeability than equivalent passive hyperthermia
No full textData availability statement: The data that support the findings of this study are available from the corresponding author upon reasonable request.Copyright © 2021 The Authors. Hyperthermia and exertional heat illness increase gastrointestinal (GI) permeability, although whether the latter is only via hyperthermia is unclear. The aim of this pilot study was to determine whether different changes in GI permeability, characterized by an increased plasma lactulose:rhamnose concentration ratio ([L:R]), occurred in exercise hyperthermia in comparison to equivalent passive hyperthermia. Six healthy adult male participants (age 25 ± 5 years, mass 77.0 ± 6.7 kg, height 181 ± 6 cm, peak oxygen uptake VO2peak [urn:x-wiley:2051817X:media:phy214945:phy214945-math-0001] 48 ± 8 ml.kg−1.min−1) underwent exercise under hot conditions (Ex-Heat) and passive heating during hot water immersion (HWI). Heart rate (HR), rectal temperature (TCORE), rating of perceived exertion (RPE), and whole-body sweat loss (WBSL) were recorded throughout the trials. The L:R ratio, peak HR, change in HR, and change in RPE were higher in Ex-Heat than HWI, despite no differences in trial duration, peak core temperature or WBSL. L:R was strongly correlated (p < 0.05) with HR peak (r = 0.626) and change in HR (r = 0.615) but no other variable. The greater L:R in Ex-Heat, despite equal TCORE responses to HWI, indicates that increased cardiovascular strain occurred during exercise, and exacerbates hyperthermia-induced GI permeability at the same absolute temperature
No effect of repeated post-resistance exercise cold or hot water immersion on in-season body composition and performance responses in academy rugby players: a randomised controlled cross-over design
No full textFollowing resistance exercise, uncertainty exists as to whether the regular application of cold water immersion attenuates lean muscle mass increases in athletes. The effects of repeated post-resistance exercise cold versus hot water immersion on body composition and neuromuscular jump performance responses in athletes were investigated. Male, academy Super Rugby players (n = 18, 19.9 ± 1.5 y, 1.85 ± 0.06 m, 98.3 ± 10.7 kg) participated in a 12-week (4-week × 3-intervention, i.e., control [CON], cold [CWI] or hot [HWI] water immersion) resistance exercise programme, utilising a randomised cross-over pre-post-design. Body composition measures were collected using dual-energy X-ray absorptiometry prior to commencement and every fourth week thereafter. Neuromuscular squat (SJ) and counter-movement jump (CMJ) performance were measured weekly. Linear mixed-effects models were used to analyse main (treatment, time) and interaction effects. There were no changes in lean (p = 0.960) nor fat mass (p = 0.801) between interventions. CON (p = 0.004) and CWI (p = 0.003) increased (g = 0.08-0.19) SJ height, compared to HWI. There were no changes in CMJ height (p = 0.482) between interventions. Repeated post-resistance exercise whole-body CWI or HWI does not attenuate (nor promote) increases in lean muscle mass in athletes. Post-resistance exercise CON or CWI results in trivial increases in SJ height, compared to HWI. During an in-season competition phase, our data support the continued use of post-resistance exercise whole-body CWI by athletes as a recovery strategy which does not attenuate body composition increases in lean muscle mass, while promoting trivial increases in neuromuscular concentric-only squat jump performance.

Frontal dynamics of a buoyancy‐driven coastal current : quantifying buoyancy, wind, and isopycnal tilting influence on the Nova Scotia Current
No full textAuthor Posting. © American Geophysical Union, 2018. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Journal of Geophysical Research: Oceans 123 (2018): 4988-5003, doi:10.1029/2017JC013338.The focus of this study is on the relative roles of winds and buoyancy in driving the Nova Scotia Current (NSC) utilizing detailed hydrographic glider transects along the Halifax Line. We define a Hydrographic Wind Index (HWI) using a simplistic two‐layer model to represent the NSC and its frontal system. The HWI is based on local characteristics of the density front extracted from the glider data (e.g., frontal slope). The impact of wind‐driven isopycnal tilting on the frontal slope is estimated and corrected for to accurately scale the buoyancy‐driven component of the NSC. Observations from independent current profilers deployed across the NSC confirm that the HWI captures the low‐frequency variability of the NSC. The monthly wind‐driven flow is estimated to represent between 1.0% (±0.1%) and 48% (±1%) of the total alongshore currents, with a yearly mean of about 36% (±1%). We demonstrate that using local conditions is more appropriate to the study of buoyancy‐driven currents ranging over distances on the order of urn:x-wiley:jgrc:media:jgrc22972:jgrc22972-math-0001(100 km), compared to the traditional approach based on upstream conditions. Contrary to the traditional approach, the HWI is not affected by the advective time lag associated with the downshelf propagation of the buoyant water coming from the upstream source. However, the HWI approach requires high‐resolution data sets, as errors on the estimates of the buoyancy‐ and wind‐driven flows become large as the sampling resolution decreases. Despite being data intensive, we argue that the HWI is also applicable to multisource currents, where upstream conditions are difficult to define.Ocean Tracking Network (OTN) Grant Number: 375118-08;
