Background: The management of cleft lip and palate aims at improving the patient's aesthetic and functional outcomes. Delaying primary repair can disrupt the patient's functional status. Long-term follow-up is essential to evaluate the need for secondary repair or revision surgery. This article presents the epidemiology of cleft lip and palate, including comprehensive patient characteristics, the extent of delay, and secondary repair at our institutional center, the Bandung Cleft Lip and Palate Center, Faculty of Medicine, Universitas Padjadjaran, Bandung, Indonesia. Methods: This retrospective study aimed to determine the epidemiology and recurrence rates of cleft lip and palate at the Bandung Cleft Lip and Palate Center, Indonesia, from January 2007 to December 2021. The inclusion criteria were patients diagnosed with cleft lip and/or palate. Procedures such as labioplasty, palatoplasty, secondary lip and nasal repair, and alveolar bone grafting were performed, and data on recurrence were available. Results: In total, there were 3,618 patients with cleft lip and palate, with an age range of 12 months to 67 years. The mean age was 4.33 years, and the median age was 1.35 years. Males predominated over females in all cleft types (60.4%), and the cleft lip was on the left side in 1,677 patients (46.4%). Most cases were unilateral (2,531; 70.0%) and complete (2,349; 64.9%), and involved a diagnosis of cleft lip and palate (1,981; 54.8%). Conclusion: Delayed primary labioplasty can affect daily functioning. Primary repair for patients with cleft lip and palate may be postponed due to limited awareness, socioeconomic factors, inadequate facilities, and varying adherence to treatment guidelines. Despite variations in the timing of primary cleft lip repair (not adhering to the recommended protocol), only 10% of these patients undergo reoperation. Healthcare providers should prioritize the importance of the ideal timing for primary repair in order to optimize physiological function without compromising the aesthetic results.

A thyroid cartilage fracture is a rare entity and can be overlooked easily. Such cases are difficult to diagnose, and assessment and treatment guidelines are difficult to determine. CT of the neck region may be useful when acute airway intervention is not required or when more information regarding the neck's anatomy is required for management decisions. We describe a case of a thyroid cartilage fracture with displacement. In the emergency department (ED), neck CT and fiberoptic nasopharyngoscopy were used to assess the status of the patient's (a male) vocal chords immediately. He remained unable to phonate continuously. After an immediate assessment, we decided to use steroid and conservative therapy. The patient had a good recovery and was without symptoms one month after injury. There is no question that early surgical repair of neck injuries affords the best results for airway and voice patency in most cases however, we suspect that surgical repair is not needed in all cases. Early recognition and an accurate therapy plan for a thyroid fracture with displacement are essential. Therefore, the emergency physician's immediate and careful decision based on endoscopy and neck CT is important for the patient's long-term recovery.

The report of the Korean Board of Audit and Inspection(BAI) on May 2007 indicates the problems of Life Cycle Cost (LCC) analysis and evaluation in the Design-Build(Turn-Key) and alternative bidding system. The point which the report indicates is that the cost estimation system for LCC analysis has nothing in common each other and there's no consistency among the repair cycle and ratio per facilities parts. For solving these problems, BAI demands the establishment of the guidelines for LCC analysis and evaluation from the competent authority Korean Ministry of Construction And Transportation(MOCT). The objective of this study is to develop the improvement directions for LCC analysis and evaluation which are suitable to the public construction projects especially for the Design-Build and alternative bidding system in Korea. For this study, the LCC related raws and regulations, LCC analysis guidelines of public cooperations, actual condition of LCC analysis and evaluation which include, the elements of LCC, the estimation rules of the initial cost and the maintenance cost, the analysis standards of time value of money, etc. are investigated to provide the improvement directions for LCC analysis and evaluation.

This study proposes a BIM-based space model generation framework for managing maintenance history in apartments. While BIM adoption in design and construction phases is increasing, its use in operation and maintenance remains limited, particularly in the continuous utilization of as-built BIM models. To address this, the study introduces a methodology for automated space model generation using DYNAMO, analyzing 1,875 maintenance records and long-term repair plans from two apartment projects over two years. The framework was applied to case projects, achieving a 100% space model creation rate for dedicated spaces and 108.91% for public spaces, proving its applicability. This suggests that the automated space model generation process proposed in this study is applicable. The significance of this study is that it presents a model transition framework for the operation and maintenance phase of the as-built BIM model. In addition, it is of research value that a simplified BIM space model is proposed to overcome the limitation of not being able to manage the history of each part in the current maintenance phase. This study can be utilized as a basis for future BIM guidelines applicable to operation and maintenance phases and delivery guidelines for as-built BIM models.

A pilot study was performed to examine the feasibility of UV disinfection system and the reactivation of indicator microorganisms (TC, FC, E. coli) after UV irradiation for agricultural reuse of reclaimed water. Photoreactivation and dark repair enable UV-inactivated microorganisms to recover and may reduce the efficacy of UV inactivation, which might be drawbacks of the UV disinfection method. The effluent of biofilter for 16-unit apartment house was used as input to the UV disinfection system, and average SS and BOD concentration were 3.8 and 5.7 mg/L, respectively, and the mean level of total coliform was in the range of $1.0\times10^4$ MPN/100mL. UV disinfection was found to be effective and it reduced mean concentration of indicator microorganisms (total coliform, fecal coliform, and E. coli) to less than 100 MPN/100mL within 60s exposure using 17, 25, and 40W lamps. Two UV doses of 6 and 16 mW$\cdot$s/$\textrm{km}^2$ were applied and microorganisms reactivation was monitored under the dark, photoreactivating light, and solar irradiation. Microorganisms reactivation was observed in the UV dose of 6 mW$\cdot$s/$\textrm{km}^2$, and numbers increased up to 5% at the photoreactivating light and 1% at the dark. However, microorganisms were inactivated rather than reactivated at the solar radiation and numbers decreased to non-detectible level about below 2 MPN/100mL in 4 hours. In the case of 16 mW$\cdot$s/$\textrm{km}^2$, microorganism reactivation was not observed indicating that UV dose might affect the reactivation process such as photoreactivation and dark repair. Therefore, concerns associated with microorganism reactivation could be controlled by sufficient UV dose application. Agricultural reuse of reclaimed water might be even less concerned due to exposure to the solar irradiation that could further inactivate microorganisms. The pilot study result is encouraging, however, sanitary concern in water reuse is so critical that more comprehensive investigation is recommended.

Public rental housing in Korea has been initially provided for residential stability of low-income household focusing on solving quantitative insufficiency since 1980s. In the process of early stage of designing and planning public rental housing, qualitative aspects of considering children were not primary concern. This study aims to analyze the priority of environmental improvement of outdoor spaces for children's safety in public rental housing. First, literature review was performed in the reference of local residential safety guidelines, Universal Design, and CPTED guidelines. In each guidelines, common safety planning factors for children were extracted within different types of outdoor spaces. Second, based on literature analysis, residents evaluated importance and satisfaction level by different safety types, outdoor space type, and environmental planning factors. In results, residents evaluated high importance and showed low satisfaction for crime and traffic safety. Through IPA, facilities and parking space was evaluated where improvement is needed for the first priority, and planning factors were mostly concerned with surveillance and safety management system. Result shows general concern of public rental housing residents, about weak facility management and security system, and about socially isolated environment which heightened the fear of crime safety. Overall, poor maintenance of the complex environment and decrepit facilities are constantly raising risk of safety accidents especially for children. Considering residents' concern, environmental improvement should be considered in perspective of not only physical repair, but also facility management and security system.

The purpose of this study is to improve the repair and reinforcement of cultural construction assets made of wood and develop seismic countermeasures. The existing regulations for the earthquake proofing of cultural assets are termed 'Regulations concerning earthquake disasters affecting cultural assets' of the cultural heritage administration, which only specifies the reporting of damage to cultural assets after the occurrence of an earthquake. Since 2013, Korea has been studying the introduction of a seismic evaluation system consisting of experts by referring to the 'Guideline for the diagnosis and reinforcement of important cultural properties in Japan. The earthquake proofing of wooden cultural assets in Japan is assessed by experts using a scoring system similar to the one in Korea, but the system in Japan is managed in three steps, viz. before, during and after the occurrence of the earthquake. In order to extend the existing management system by focusing on the repair of the damage after the occurrence of an earthquake, it is necessary for Korea to cultivate experts for the regular management of cultural assets, establish seismic criteria for them, and introduce a regular management system through a civil organization related to construction. By examining the current status of wooden cultural assets, it is necessary to develop various seismic diagnosis techniques and produce guidelines for the repair and reinforcement of individual wooden cultural construction assets following their identification.

Germline mutations in cancer causing genes result in high risk of developing cancer throughout life. These cancer predisposition syndromes (CPS) are especially prevalent in childhood brain tumors and impact both the patient's and other family members' survival. Knowledge of specific CPS may alter the management of the cancer, offer novel targeted therapies which may improve survival for these patients, and enables early detection of other malignancies. This review focuses on the role of CPS in pediatric high grade gliomas (PHGG), the deadliest group of childhood brain tumors. Genetic aspects and clinical features are depicted, allowing clinicians to identify and diagnose these syndromes. Challenges in the management of PHGG in the context of each CPS and the promise of innovative options of treatment and surveillance guidelines are discussed with the hope of improving outcome for individuals with these devastating syndromes.

The use of VPI impregnated mica tape as high voltage insulation for large rotating electric machines requires a careful balance of processes and materials to obtain the desired electrical, mechanical and thermal characteristics. The stator insulation systems such as epoxy bonded high voltage mica tape have been produced for many years. One such system employing an epoxy and anhydride impregnating resin developed by Hyundai Heavy Industries, Co. (hereafter, HHI), to satisfy customer requests for an epoxy bonded insulation system. HHI applies the following electrical and thermal evaluations such as dielectric breakdown, voltage endurance, dissipation factor vs. temperature, isothermal weight loss, and so on. A detailed laboratory evaluation can describe specific physical limitations for an insulation system and permit development of long-term operation guidelines that permit full utilization of the proposed system. HHI has found these evaluations very helpful in qualifying insulation system for the repair of both large motors and generators.
