Important Elements and Features of Neighborhood Landscape for Aging in Place: A Study in Hong Kong.

With rapid growth in the aging population around the world, the promotion of aging in place has become more significant in recent years. Many neighborhood landscape elements and features have been revealed by accumulating research findings to be critical to aging in place. However, they are usually studied separately or in small groups. Little has been done to examine the relative importance of these elements and features when brought together, from the older adult's point of view. In this context, the current study investigated the perceived importance for older adults of 22 selected neighborhood landscape elements and features. A questionnaire survey was conducted in 17 public rental housing estates in Hong Kong with proportions of older residents (aged 65 or above) between 20 and 40%. According to the 426 collected samples, older adults considered as highly important landscape elements and features that contribute to comfort and help them avoid hazards, such as good ventilation, protection from severe sunshine/rain, body support, and good hygiene, while elements were thought to potentially bring hazards while not being necessities for older adults' outdoor experience were considered least important, including portable chairs, outdoor tables, plants that can be touched, closeness to children's playgrounds, small spaces for solitude, water features, and fitness equipment. After integrally interpreting the findings regarding perceived importance with other collected data, some landscape design suggestions are generated to supplement existing guidelines and recommendations concerning older adults' well-being and quality of life. These findings can inspire future research and landscape design that prioritize promoting aging in place.

Prevalence of Dental Caries and Oral Hygiene Status among Juvenile Prisoners in the Kingdom of Saudi Arabia.

The aim of the study was to determine the prevalence of dental caries and oral hygiene status among juvenile prisoners in Riyadh, Kingdom of Saudi Arabia. A total of 105 prisoners aged between 12 and 17 years of age from the Juvenile Detention Center were included in the study. Any prisoner with systemic illness and being noncooperative were excluded from the study. Clinical examinations were performed under an artificial light source using a disposable mouth mirror and explorer while seated on a portable chair. The dental caries experience was measured as the number of decayed, missing, or filled permanent teeth (DMFT) using DMFT score. The oral hygiene index (OHI) was assessed by the Greene and Vermillion method. The data collected were analyzed using Statistical Package for the Social Sciences version 16. The mean age of the sample was 16.33 years, with 74.3% of the prisoners in the 16 to 17-year-old group. The dental caries index measured by calculating the mean DMFT of the juvenile prisoners increased with age. The DMFT scores of 9.09 (4.388) for 78 juvenile prisoners aged 16 to 17 years followed by 9.00 (2.925) for 19 prisoners aged 14 to 15 years and 7.13 (1.808) for 8 prisoners aged 12 to 13 years were observed. The oral hygiene status of the prisoners showed that more than half of the juvenile prisoners included in the study had poor (53.3%) oral hygiene and less than half had fair (45.7%) oral hygiene and only one participant demonstrated good oral hygiene. The juvenile prisoners had high prevalence of dental caries and fair-to-bad oral hygiene, indicating poor oral health status. Furthermore, the study emphasizes the need for special attention from the concerned health authorities, voluntary organizations, and surrounding dental colleges in meeting the oral health needs of this group. The study provides an important database for decision makers to take on the challenge of reducing dental caries among juvenile prisoners.

Prevalence and severity of periodontal disease among Iraqi twin population

The aims of this study were to determine the prevalence of periodontal disease for two clinical parameters: probing pocket depth (PPD) and attachment loss (AL) among twins, and to compare between mono zygote (MZ) and dizygote (DZ) twins, in addition to the evaluation of the degree to which MZ and DZ twins are concordant for four clinical parameters. The sample consisted of 75 pairs of twins reared together, with an age range of 16-45 years. They were selected from different cities of Iraq. The examination was carried out using a graduated Williams’s periodontal probe, on a portable chair, using artificial light. The clinical examination included recording of PPD and AL. Results of the present study have shown significant difference in periodontal pocket depth between MZ and DZ group; which was higher in MZ were higher than in DZ twins. No significance difference was found between MZ and DZ twins in attachment loss. Results from this study have demonstrated that the degrees of concordance for MZ were higher than in DZ twins for PPD and AL and there were significant differences between MZ and DZ twins. These findings provide evidence that genetic factors play an important role in the etiology of periodontal disease. Key words: Periodontal disease, probing pocket depth, attachment loss among mono zygote, dizygote.

J. Chasteen (Rugby, Pistol), Bruce Roach (Sir Hugh Evans), Dan Hillaker (Nym), Kate Needham (Robin), and others. Since The Merry Wives of Windsor is one of the less frequently performed of Shakespeare’s comedies, it came as something of a surprise that both major outdoor summer Shakespeare festivals in Missouri chose to perform the play during the 2009 season. Both festivals are set up along the lines established many years ago by the free Shakespeare in Central Park program originally devised by Joseph Papp. Both festivals advertise free admission, though in Kansas City a minimal donation of $5 seems all but obligatory, with two festival workers standing ready to accept it at the festival’s lone entrance gate; and in St. Louis a “bills for Will” monetary [End Page 150] donation is encouraged at the conclusion of the performance. Both festivals situate their performances in the midst of “green world” park land that seems ideally suited for Shakespearean comedy. The St. Louis festival is located in the middle of Forest Park, an impressive expanse of green space that originally served as the grounds for the 1904 St. Louis World’s Fair. The Kansas City festival operates within Southmoreland Park, a rather small, narrow stretch of greenery wedged in between the city’s largest art museum and a small residential neighborhood that adjoins the well-known and heavily visited Country Club Plaza. Both festivals invite theatregoers to bring blankets or lawn chairs, with designated areas assigned for those choosing each alternative (with those choosing the blanket option granted a closer proximity to the stage so that their view will not be blocked by those using portable chairs). And both festivals offer an assigned close-up seating section for those willing to pay $10 (in St. Louis) or $20 (in Kansas City). The fact that both festivals are able to take advantage of hillsides that slope gently down to their stages makes this series of options viable, while ensuring decent sight lines for just about all spectators. In St. Louis, I opted for a $10 reserved seat, while in Kansas City I was able to secure a spot for my lawn chair that provided an excellent stage-center vantage point. Both productions took some short cuts in order to arrive at nearly identical running times of two hours, thirty minutes, including a fifteen-minute intermission. In St. Louis, the most obvious omission involved the character of the Welsh parson, Sir Hugh Evans, whose role was completely eliminated. As a result, the Host of the Garter Inn served as primary peacemaker in the play’s opening confrontation between Falstaff and his minions and Justice Shallow, and Slender took over Evans’s part in the mock-duel sequence with Doctor...

Does chair type influence outcome in the timed “Up and Go” test in older persons?

Objective To test the effects of the use of a collapsible, portable chair (chair B), as opposed to a ‘standard’ chair (chair A), on the outcome of the timed “Up and Go” (TUG) test. Design Cross-sectional. Setting Multipurpose senior centres. Participants Mobile older persons (N=118, mean age 77 years (range 62–99 years)). Outcome measures Time to complete the timed “Up and Go” test using chair A and chair B, and inter-rater agreement in the time scores. Results Time taken to complete the TUG test did not differ by chair type [median (interquartile range, IQR) = 12.3 (9.53–15.9) and 12.6 (9.7–16.6)] seconds for Chair A and B respectively, p-value=0.87. In multiple regression analyses, factors that impacted on time difference in test performance for the two chairs were use of a walking aid during the test [Odds ratio (OR) = 3.7 95%CI 1.1–11.9, p=0.031], observed difficulty with mobility (OR= 27.7 95%CI 2.6–290, p=0.006), and a history of arthritis in the knees (OR= 2.9 95%CI 1.0–8.7, P=0.05). In an inter-rater agreement analysis, no significant difference was found between time scores recorded by the two raters; median (IQR) = 12.4 (10.9–15.9) and 12.3 (7.2–59.1) seconds for the occupation therapist and for the research assistant, respectively (Wilcoxon matched pairs test, p=0.124, Spearman correlation coefficient = 0.99, p Conclusion The use of a portable canvas chair with standardised specifications offers an acceptable alternative to the use of a ‘standard’ chair in assessments of fall risk using the TUG test in field settings where field workers are reliant on public transport.

Are portable folding chairs useful to combat orthostatic hypotension?

The effect of sitting on a derby chair (height, 48 cm), fishing chair (38 cm), and footstool (20 cm) on the improvement of postural hypotension was studied serially in 8 patients with autonomic failure. The increment in blood pressure during sitting was higher by using a lower portable chair. This was related to an increasing cardiac output at lower sitting heights. The fishing chair was, according to our patients' experience, most useful.

Association of Muscle Strength with Functional Status of Elderly People

We have studied the association of muscle strength (quadriceps, biceps, handgrip), measured by a portable chair technique, with functional status (Barthel Index, manual dexterity, Mental Test Score, history of falls, fracture, prescribed drugs), in a sample of 92 elderly subjects attending a Local Authority Day Centre and Day Hospital. Anthropometric measurements and hand-grip strength were also measured in 30 young controls. Muscle area, mass and strength were significantly greater in young controls. Elderly men had significantly greater muscle area, mass and strength than elderly women. Muscle strength correlated with several measures of functional status. Using stepwise multiple regression, an independent association of muscle strength with manual dexterity, Barthel Index and receipt of domiciliary services is demonstrated.

Portable dental chair

SummaryTo many people, dental care is solely for the relief of pain or infection; to others i To is a luxury that cannot be afforded because of monetary or geographic barrierS. Although the handicapped may be unable to travel to receive dental care services, they should be the recipients of definitive care including the prevention of disease.The dentist and his staff are more able to leave the confines of a fixed operatory and travel with portable equipment to urban and rural areas. The goal is to provide more than just emergency treatment, with'the type and quality of care partly dependent on the capabilities of transportable equipment.system is completed, using handtightened knobs and thumbscrews to secure the attachments. The system is easy to clean and maintain, being of simple design and composed of durable, corrosion‐resistant materialS. Repairs require a few common tools and, because of compactness and lightweight, assembled modules or subsystems can be containerized for shipment if replacements are required.The concept of a portable dental clinic is not new but its function as a total care unit has been directly proportional to bulk, as might be seen in the mobile van concept. With modem technology, miniaturized devices are as effective as or are highly improved over larger couterpartS. By using smaller, light‐weight components in a dental treatment unit, the system can be more easily transported, even to the point of being hand carried.The design criteria established for the portable chair system are based on the concept of miniaturization. The components are commercially available and, with a few modifications, all assemblies can be attached to the dental chair. Assembly and disassembly of theOne problem encountered with portable dental systems is the number of containers needed for large modular components and chair. The total system is packaged into one durable weatherproof container weighing 150 Ib. Two men can easily carry the container over short distances or it can be transported in a small motorized vehicle, or in a trailer drawn by an animal.Because of its compact size, a dental operatory can be set up in a limited space and design features permit use even when based on soft ground. If electricity and compressed air are not available, they can be supplied by a small generator and a compact quiet air compressor.There is a growing need to develop equipment and methods for portable dental treatment. The portable chair design has removed much of the unnecessary bulk and weight yet has retained the function of comprehensive dental care.

Portable Chair Type Whole-Body Counter

A portable chair type whole-body counter has been studied which is for internal contamination monitoring of the subjects working in nuclear facilities. A 3″φx3” Nal(Tl) crystal housed in a lead collimator is used. Findings from the study are as follows: the crystal size does not influence the screening level of internal contamination defined as a three standard deviation above the mean level of distributed counts obtained for the uncontaminated subjects. Reasonable shieldings of both detector and chair may be more than 3.8 cm of lead. A three-channel pulse height analyzer set in the γ energy region above 0.2 MeV will be suitable for the monitoring. The detection sensitivities for stomach, lung, kidney and small intestine to a 137Cs source are not lower than in the case of the homogeneous distribution in the whole body revealed by phantom study.

Dos obras de Welton Becket (EE. UU.)

Nassau Veterans Memorial Coliseum . It is oval in shape and can house sports competitions and gymnastic events, musical productions, circuses and it can be used to show films as well as for expositions, meetings and conventions. From the plaza, entrance is achieved through a mirrored gallery circumscribing the building and that communicates with the interior corridor that sorrounds the court. It holds more than 11,000 people and there are telescopic platforms that unfold at court-level and portable chairs that increase this capacity to a total of 16,500. The building is covered by a steel frame, limited on the outside by a wide metallic cantilever. The whole system is supported by 32 large concrete columns, in U shape, that show on the exterior facade. The Coliseum has theatrical lighting and sound installations which adapt it to each of the different types of events the building can be used for. Under the adjacent plaza a large underground exhibition hall has been set up to serve the Coliseum. More than 5,000 m 2 in area, this space can be subdivided by folding panels as needed. Bullock’s Shopping Center in Northridge . The main feature of this large department store is that it has been treated entirely as a stage for the various goods that are on display there. Moreover, its design has broken with the traditional box shape typical of this type of building, replacing it with a polyhedral volume for a more dynamic effect. Great importance has been given in this building to architectonic spaces as well as the lighting system and the decor. Thus, the different areas are given more or less importance by means of the various lighting effects, while the decoration and architectonic forms differentiate and limit the various display areas. A system of ornaments and mobile partitions gives the unit great flexibility thus permitting modifications as per the needs of each particular moment.

Assembly Hall de la Universidad de Illinois, USA

The Assembly Hall of Illinois University has been constructed with an original reinforced and prestressed concrete structure. It has a seating capacity for 15,565 spectators, in addition to space for press, radio and TV. staff, for the performers, and for invalid spectators who use wheeled chairs. The seating capacity can be further extended by providing 1,500 portable chairs. This hall can be adapted to many uses, and has suitable equipment and installations for assemblies, theatrical and musical performances, ice skating, sports competitions and circus shows. The provision of this magnificent hall has made it possible to organise at the University of Illinois many activities that were not practicable before.

Dental Caries and Periodontal Diseases among Ethiopian Civilians

THE Interdepartmental Committee on Nutrition for National Defense (1) conducted a nutiition surv-ey in Ethiopia during the fall of 1958. A team of American and Ethiopianl nutritionists, food technologists, biochemists, plhysicians, and a dentist visited widely withiin the country. Inl each area visited an attempt was made to assess certain physical characteristics in a selected sample of men, womeni, and clhildren. Blood and urine samples were taken for biochemical analysis. Data concerning food productioni and availability and dietary patter ns were also obtained. I)ental examinations, included as a part of the physical appraisals, were completed on 1,085 civilian males and females aged from 5 tlhrough 84 years. This sample included residents of 8 of ii geographic regions visited by the team (fig. 1), and it had representation from the major ethnic groups. The survey presented an opportunity to study oral diseases in a population for which little information has been available. All dental observations were made by the one dentist, usin.g a portable chair and standard dental mirrors and explorers, under natural light. Findings for dental caries, fluorosis, molar attrition, periodontal diseases, dental calcu1lus, and debris are discussed below.

Acoustics of the Rochester (New York) War Memorial Auditorium

This arena-type auditorium with a stage at one end has a volume of 3.24 million cubic feet, seats 5774 persons in stationary chairs and a total of nearly 10 000 with additional, portable chairs. Both the stationary and the portable chairs have upholstered seats. The acoustical hazard of concave rear wall and opposite wall containing the proscenium opening was ameliorated by special treatment. A combination structural-acoustical ceiling was used. The design objective of a reverberation time of about 2.5 seconds in the unoccupied room at 500 cps was attained without adjustment. The results of reverberation-time measurements are shown and discussed. The public-address system is described and the subjective assessment of the auditorium is mentioned.
