The phenomenon of residual stress in optical lens injection molding affects the quality of optical devices, with the refractive errors that are caused by geometric errors being the most serious, followed by the reduced accuracy and function of optical components; it is very important to ensure that the lens geometry remains intact and that the refractive index is reduced. This paper uses a photoelastic stress compensation method for measurement verification along with fuzzy theory to reorganize a set of processes that can be used to evaluate the residual stress of a product, whereby the use of corresponding theoretical formulas can effectively quantify and measure the residual stress of the product. A mold flow simulation is used to analyze the molded optical components and determine the feasibility of evaluating the quality of the lens. Through the measurement of the refractive stress value of the optical components, the molding quality of the lens can be improved, and its force distribution effects can be investigated. Geometric analysis and shear stress affect the performance of optical components, and these errors may also cause irreparable problems during secondary processing. Therefore, it is crucial to reduce the residual stress of optical components. When the stress distribution is uniform and the internal melting pressure is reasonably configured, the product’s shrinkage rate can be controlled; the method for determining the residual stress is the core theme of this research.

Purpose Craniofacial anomalies (CFA) often result in growth abnormalities of the facial skeleton adversely affecting function and appearance. The functional problems caused by the structural anomalies include upper airway obstruction, speech abnormalities, feeding difficulty, hearing deficits, dental/occlusal defects, and cognitive and psychosocial impairment. Managing disorders of the craniofacial skeleton has been improved by the technique known as distraction osteogenesis (DO). In DO, new bone growth is stimulated allowing bones to be lengthened without need for bone graft. The purpose of this clinical focus article is to describe the technique and clinical applications and outcomes of DO in CFA. Conclusion Distraction can be applied to various regions of the craniofacial skeleton to correct structure and function. The benefits of this procedure include improved airway, feeding, occlusion, speech, and appearance, resulting in a better quality of life for patients with CFA.

Lung cancer is one of the most commonly diagnosed cancers across Northern America and Europe. Treatment options offered are dependent on the type of cancer, the location of the tumor, the staging, and the overall health of the person. When surgery for lung cancer is offered, difficulty swallowing is a potential complication that can have several influencing factors. Surgical interaction with the recurrent laryngeal nerve (RLN) can lead to unilateral vocal cord palsy, altering swallow function and safety. Understanding whether the RLN has been preserved, damaged, or sacrificed is integral to understanding the effect on the swallow and the subsequent treatment options available. There is also the risk of post-surgical reduction of physiological reserve, which can reduce the strength and function of the swallow in addition to any surgery specific complications. As lung cancer has a limited prognosis, the clinician must also factor in the palliative phase, as this can further increase the burden of an already compromised swallow. By understanding the surgery and the implications this may have for the swallow, there is the potential to reduce the impact of post-surgical complications and so improve quality of life (QOL) for people with lung cancer.

Abstract In Poland, the last 15 years have been marked by various, numerous regeneration projects of historic cities that were supposed to improve the citizens quality of life and their security, as well as to create an attractive tourist offer. Those programs were often focused on the renewal, reshape and modernization of public squares. Such changes never go unnoticed. On contrary, these are frequently associated with criticism, debate and disagreements. The research has been focused on the analysis of regeneration projects from selected Market Squares in historic cities and town centres in Lower Silesia. The main aim was to exhibit the medieval origin of those squares and recently introduced contemporary layout. Moreover it was to present diverse opinions regarding square’s form and function, that can be crucial in understanding the architects, planners and citizens’ points of view and their ‘feelings’ towards the space.

Abstrak Inovasi merupakan suatu hal penting yang harus dimiliki oleh sebuah organisasi pemberi layanan sektor publik. Instansi pemerintah sebagai pemberi layanan dituntut memiliki inovasi untuk meningkatkan kualitas pelayanan kepada masyarakat. Penelitian ini bertujuan untuk membandingkan inovasi pelayanan sektor publik di RSUD Prof. Margono dan Lembaga Permasyarakatan Nusakambangan Cilacap. Metode penelitian yang digunakan adalah metode deskriptif kualitatif. Teknik pengumpulan data melalui wawancara, observasi, dan dokumentasi. Temuan dalam penelitian ini adalah: 1). Kurangnya personil pegawai yang sesuai dengan tugas dan fungsinya; 2). Kuangnya kesejahteraan pegawai sehingga kinerja pegawai rendah dan tidak berkualitas; 3). Pegawai berpendidikan rendah sehingga tidak sesuai dengan beban tugas dan fungsinya. Rekomendasi untuk kedua Lembaga sector public tersebut dalam penelitian ini adalah: 1). Penambahan personel pegawai sesuai dengan tugas dan fungsinya sehingga cakupan kewenangannya luas; 2) Lebih memperhatikan kesejahteraan pegawai sehingga pegawai termotivasi untuk bekerja dengan baik dan berkualitas; 3) Memberikan Kemudahan kepada pegawai yang ingin melanjutkan pendidikannya kejenjang yang lebih tinggi sehingga kualitas Pendidikan personel lebih seimbang dengan beban kerja. Kata Kunci: Inovasi, Pelayanan, SektorPublik   Abstract Innovation is an important thing that must be owned by an organization that provides public sector services. Government agencies as service providers are required to have innovations to improve the quality of services to the community. This study aims to compare public sector service innovations in hospitals. Prof. Margono and the Nusa kambangan Penitentiary. The research method used is descriptive qualitative method. Data collection techniques through interviews, observation, and documentation. The findings in this study are: 1). Lack of employee personnel in accordance with their duties and functions; 2). The lack of employee welfare so that employee performance is low and not qualified; 3). Employees have low education so that it is not suitable with their work load and function. The recommendations for the two public sector institutions in this study are: 1). The addition of employee personnel in accordance with their duties and functions so that the scope of their authority is broad; 2) Pay more attention to employee welfare so that employees are motivated to work well and quality; 3) Providing convenience to employees who want to continue their education to a higher level so that the quality of personnel education is more balanced with the workload. Keywords: Innovation, Service, Public Sector
