Low back pain, pain that is felt in the affected anatomical area with a variety of long occurrence of pain. This pain feels lumbar or lumbo-sacral. Workers of tofu home industry are at risk of low back pain due to their activities such as the position of bending, lifting and carrying heavy loads. This research aim to factors that risk against the incident of low back pain. Total sample of 132 respondents: 66 cases and 66 controls were selected randomly from workers of tofu home industry. Data analysis using Chi Square and logistic regression to know the most dominant factor. There was relationship of employment, back posture, heavy weights with low back pain (P <0.05). There was not relationship age, sex, smoking, body mass index and physical activity with low back pain (p>0.05). Multivariate analysis using logistic regression showed the most dominant working period affecting low back pain. The study found that low back pain was a relevant health problem among workers of tofu home industry. The policy of arranging breaks and lifting techniques is required to prevent low back pain.

Abstract Bisimulation and bisimilarity are fundamental notions in comparing state-based systems. Their extensions to a variety of systems have been actively pursued in recent years, a notable direction being quantitative extensions. In this paper we enhance a categorical framework for such extended (bi)simulation notions. We use coalgebras as system models and fibrations for organizing predicates—following the seminal work by Hermida and Jacobs. Endofunctor liftings are crucial predicate-forming ingredients; the first contribution of this work is to extend several extant lifting techniques from particular fibrations to $\textbf {CLat}_\wedge $-fibrations over $\textbf {Set}$. The second contribution of this work is to introduce endolifting morphisms as a mechanism for comparing predicates between fibrations. We apply these techniques by deriving some known properties of the Hausdorff pseudometric and approximate bisimulation in control theory.

AbstractPurse string sutures in superficial musculoaponeurotic system (SMAS) plication facelifts may cause technique-related problems, such as soft tissue deformities, dimpling, and bulkiness inside and between the independent sutures. Therefore, the authors have developed a new approach named the multiple rhomboid vector (MRV) suture. A total of 103 patients (89 female, 14 male patients; median age: 57 years) received a primary rhytidectomy with the MRV SMAS plication suture in our clinic (2015–2017). Intraoperative time to perform the suture per side was recorded. Postoperative complications and dimpling and bulkiness of subcutaneous tissues were judged by three independent surgeons from 1 (= none) to 4 (= extreme) after 1 week, 1, 3, 6, and 12 months. A standardized survey, the FACE-Q questionnaire, was performed to evaluate postoperative patient satisfaction. Mean time to perform the suture was 5:14 minutes per side (minimum: 3:20 minutes, maximum: 5:53 minutes; standard deviation: 0:51 minutes). During the follow-up period, four complications were detected (two cases of temporary neurapraxia of the marginal branch of the mandibular nerve {n = 2 [1.9%]} and two cases of retroauricular hematoma {n = 2 [1.9%]}). Postoperative dimpling or bulkiness of subcutaneous tissues was judged as absent. Overall patient satisfaction rate, after the surgery was performed, was measured as “very high.” The MRV suture offers a combined horizontal and vertical suspension approach, which effectively addresses the different vectors of age-related facial soft tissue descent with complication rates equal to other surgical lifting techniques. Apart from that, it may help reduce the possibility of contour irregularities, whereby it must be noted that a thorough preoperative assessment together with the patient and surgical planning is crucial to ensure realistic expectations of the surgical outcome.

Abstract Embedding thread lift rhytidectomy, also known as “thread lifting” in China, with the natures of simple operation, less trauma and quick recovery, is progressively used in clinical practice as a new technology of face lifting. Herewith, a brief introduction of the previous advances of thread lifting techniques and materials in the facial beauty industry, combined with the discussion on various types of sutures, common complications, and the site of actions were provided. The main limitations of present thread lifting material include: (1) the use of non-absorbable sutures is liable to cause allergies and a series of complications; (2) the absorbable sutures are easily degradation, and people need to reshape in a relatively short period. Therefore, the high biocompatible spider silk was proposed as a novel material of thread lifting suture and related devices, the advantages and preliminary achievements on spider silk were also addressed.

Abstract Although wearable robotic systems are designed to reduce the risk of low-back injury, it is unclear how effective assistance is, compared to improvements in lifting technique. We use a two-factor block study design to simulate how effective exoskeleton assistance and technical improvements are at reducing the risk of low-back injury when compared to a typical adult lifting a box. The effects of assistance are examined by simulating two different models: a model of just the human participant, and a model of the human participant wearing the SPEXOR exoskeleton. The effects of lifting technique are investigated by formulating two different types of optimal control problems: a least-squares problem which tracks the human participant’s lifting technique, and a minimization problem where the model is free to use a different movement. Different lifting techniques are considered using three different cost functions related to risk factors for low-back injury: cumulative low-back load (CLBL), peak low-back load (PLBL), and a combination of both CLBL and PLBL (HYB). The results of our simulations indicate that an exoskeleton alone can make modest reductions in both CLBL and PLBL. In contrast, technical improvements alone are effective at reducing CLBL, but not PLBL. The largest reductions in both CLBL and PLBL occur when both an exoskeleton and technical improvements are used. While all three of the lifting technique cost functions reduce both CLBL and PLBL, the HYB cost function offers the most balanced reduction in both CLBL and PLBL.

The submental-cervical angle is an important anatomical landmark in neck beauty. Considered attractive and a sign of youthful when between 105° and 120°, greater values are considered a “heavy” neck or double chin and are related to the aging process and/or weight gain. The submandibular gland can also contribute to the alteration of the submental-cervical angle, increasing the area’s bulging. Neck-lifting techniques have the potential to produce important changes in the lateral view of the face, making it look more youthful, and that is more noticeable in the frontal aspect. This review focuses on the treatment of the neck, including all modifications that occur during the aging process, and postoperative procedures used to decrease the risk of complications.

BACKGROUND: Development and introduction of minimally invasive lifting techniques is considered a demanding and relevant objective of contemporary dermatocosmetology as these techniques result in nonsurgical lifting with minimal disruption of facial harmony due to the activation of a maximal number of key anatomic landmarks following the simultaneous insertion of lifting threads and hyaluronic acid fillers. AIMS: To study the clinical efficacy and safety of minimally invasive lifting technique and filling up of the tissue volume deficiency with the combination of thread lifting from the temporal approach and hyaluronic acid filler augmentation. MATERIALS AND METHODS: The study group included 193 female patients (mean age 41.3 8.5 years) with gravitational ptosis of the 1st, 2nd, and 3rd degrees. Group 1 (main) comprised 42 (21.8%) patients who underwent lifting by the method of implantation of 12 threads with shaped polydioxanone spikes DG-Lift and injection of 2 ml of hyaluronic acid biphasic filler. Group 2 (comparison) comprised 64 (33.2%) female patients who underwent lifting using only 1220 polydioxanone DG-Lift threads. Group 3 (comparison) comprised 87 (45%) female patients who received tissue volumization with 48 ml of biphasic hyaluronic acid filler in each case. RESULTS: A total of 82%, 59%, and 48% of patients in groups 1, 2, and 3, respectively, noted the optimal cosmetic result and full satisfaction with the result according to the Global Aesthetic Improvement Scale. The incidence of complications in group 1 (6.4%) was lower than that in group 2 (9.1%) and group 3 (17.7%). This is due to low invasive nature and lower tissue traumatization with the use of fewer fillers and threads to obtain optimal cosmetic effect. CONCLUSION: The proposed technique of thread lifting with biodegradable threads DG-Lift from the temporal approach combined with tissue volumization with hyaluronic acid fillers is safe and significantly effective for patients with gravitational ptosis of the 1st, 2nd, and 3rd degrees.
