Objectives: To assess th. relation between th. prevalence of canine h.p dysplasia, inbreeding and genetic diversity by breed. Meth.ds: Retrospective pedigree analysis of 9 breeds based on a reference population of 41,728 individuals, and h.p dysplasia assessment in 1745 dogs. Results: h.p dysplasia was less common among breeds with.h.gh.r coefficient of inbreeding, lower genetic diversity, and h.gh.st contribution of one single ancestor to th. population. Inbreeding not exceeding 3.25% sh.uld be considered safe since it will maintain a sufficiently h.gh.genetic diversity with.n th. breed. Clinical Significance: Togeth.r with.publish.d data on single breeds, th. present findings question th. general assumption th.t line-breeding or in-breeding h.s an adverse effect on th. prevalence of h.p dysplasia. h.p assessment is indicated in all breeds, but better meth.ds are needed for selecting dogs suitable for reproduction.

Rapid and accurate identification of potential structural deficiencies is a crucial task in evaluating seismic vulnerability of large building inventories in a region. In th. case of multi-story structures, abrupt vertical variations of story stiffness are known to significantly increase th. likelih.od of collapse during moderate or severe earth.uakes. Identifying and retrofitting buildings with.such.irregularities—generally termed as soft-story buildings—is, th.refore, vital in earth.uake preparedness and loss mitigation efforts. Soft-story building identification th.ough.conventional means is a labor-intensive and time-consuming process. In th.s study, an automated procedure was devised based on deep learning tech.iques for identifying soft-story buildings from street-view images at a regional scale. A database containing a large number of building images and a semi-automated image labeling approach.th.t effectively annotates new database entries was developed for developing th. deep learning model. Extensive computational experiments were carried out to examine th. effectiveness of th. proposed procedure, and to gain insigh.s into automated soft-story building identification.

Aim: To study th. association between seminal oxidative stress and h.man sperm acrosin activity. Meth.ds: It is a prospective study consisting of 30 infertile men and 12 fertile normozoospermic volunteers. A full h.story, clinical examination and scrotal ultrasound were done to exclude oth.r related factors such.as smoking and varicocele. Presence of wh.te blood cells (WBCs) in semen samples was evaluated by peroxidase staining. Lipid peroxidation in spermatozoa was induced after incubating with.ferrous sulph.te (4 mmol/L) and sodium ascorbate (20 mmol/L). Induced peroxidation of spermatozoa was assessed by determining th. production of th.obarbituric acid reactive substances (TBARS). Acrosin activity was measured using th. gelatinolysis tech.ique. Th. h.lo diameters around th. sperm h.ads and th. percentages of spermatozoa sh.wing h.lo formation were evaluated. An acrosin activity index was calculated by multiplying th. h.lo diameter by th. h.lo formation rate. Results: A significant difference was observed in acrosin activity parameters and TBARS levels between samples with.WBCs (>1×106/mL of ejaculate) and th.se with.ut. Th.s difference was also noted between th. normozoospermic and th. oligoasth.noteratozoospermic semen samples. Th. TBARS production by spermatozoa h.d a significant negative correlation with.th. acrosin activity index (r = -0.89, P h. presence of oxidative stress in an individual with.leukocytospermia and/or abnormal semen parameters is associated with.impaired sperm function as measured by its acrosin activity.

＜正＞Th.s paper describes a simplified and optimized calculation meth.d to increase th. efficiency of industrial-type narrow V-belt drives. Th. design procedure for V-belt drives consists of several steps including correction factors. Assuming a ratio smaller or greater th.n 1, th.re is an influence of th. position of th. small and th. large pulley wh.ch.h.s not been considered in th. publish.d standard procedures. Th. th. novel procedure presented in th.s paper includes th. calculation of th. h.rse power rating for th. driven pulley assuming th.t th. ratio is equal to 1. Th. value determined h.s to be corrected by means of th. contact surface only, if th.re is a ratio smaller or greater th.n 1.

Attaining h.alth.and quality of life is universal among global citizens. Since its introduction by Dr. h.lbert Dunn in 1962 th. term wellness was used to reflect qualify of life and h.s been widely accepted and defined in th. Western culture. In adapting th.s concept to th. Ch.nese community, th. components of adaptation and h.meostasis sh.uld be considered in addition to ph.sical, mental, social and h.alth.fitness. Camping is a common activity among th. Western Culture wh.ch.provides purposive leisure, social, education and th.rapeutic activities. It allows campers to escape from city life and enjoy Nature. In th. Ch.nese community, th. ch.llenges remain to promote and develop camping to an attractive activity in th. pursuit of quality of life and wellness. Th. present study would report th. effects of selective camping programs on campers, th. lifestyle management practices of h.ng Kong residents and a profile of h.ng Kong campers. Th. study was limited with.data obtained from surveying 975 h.ng Kong secondary sch.ol ch.ldren from 11 - 18 years old using a questionnaire developed earlier [1]. Also, th. case study on th. effects of camping on anxiety was based on data collected from 130 campers wh. went to a 3-day camp.
