This study aims to provide a real-time information to the driver by effectively operating the advanced safety device attached to the freight vehicle, thereby minimizing insecure behavior of the driver such as speeding, rapid acceleration, sudden braking, And improve driving habits to prevent accidents and save energy. Advanced safety equipment is a device that warns the driver that the vehicle leaves the driving lane regardless of the intention of the driver and reduces the risk of traffic accidents by mitigating or avoiding collision by detecting a frontal collision during driving.The main contents of this report are as follows: In case of installing a warning device on a lane departing vehicle (excluding a light vehicle) and a lorry or special vehicle with a total weight exceeding 3.5 tonnes, the driver must continue to operate unless the driver releases the function.In addition, when the automatic emergency braking system is installed, the structure should be such that the braking device is operated automatically after warning the driver when the risk of collision with the running or stopped vehicle in the same direction is detected in front of the driving lane.

Homozygous familial hypercholesterolemia (HoFH) is a rare inherited disorder that presents as abnormally elevated levels of low-density lipoprotein cholesterol and premature heart disease, requiring frequent intervention through lipid apheresis for management. The risk of perioperative cardiac events is higher in patients with HoFH because of its pathophysiological manifestations in the vascular system. Careful cardiac precautions and anesthetic assessments are necessary to ensure patient safety. In the following case report, we discuss the clinical course and anesthetic considerations for a 14-year-old girl with HoFH undergoing sedation for dental extractions and mandibular molar uprighting in an outpatient oral surgery clinic. Considerations included the use of heparin in the patient's weekly plasma lipid apheresis treatment. In order to reduce the risks of peri- and postoperative bleeding and perioperative cardiac events, the operation was scheduled for 4 days after apheresis. This allowed for adequate heparin clearance, while also reducing the likelihood of possible cardiac events. A literature review revealed no results for the outpatient management of patients with HoFH undergoing sedation for noncardiac procedures. Our reported case serves as a clinical example for physicians to be utilized in the future.

Indian Construction industry is large, volatile, and requires tremendous capital outlays. Typically, the work offers low rates of return in relation to the amount of risk involved. A unique element of risk in the industry is the manner in which disputes and claims are woven through the fibre of the construction process. Delay is generally acknowledged as the most common, costly, complex and risky problem encountered in construction projects. Because of the overriding importance of time for both the Owner and the Contractor, it is the source of frequent disputes and claims leading to lawsuits. The growing rate of delays is adversely affecting the timely delivery of construction projects. Presently construction industries are facing a lot of problems, considering that a paper assess construction stakeholder's perception to the causes of delays and its effects on project delivery. And also one case study is considered in this paper to elicit responses from construction stakeholders. The primary aim of this paper is to identify the perceptions of the different parties regarding causes of delays, the allocation of responsibilities and the types of delays, and method of minimizing the construction delays.

Recently, social technologies have been created to solve problems from businesses for the establishment of generational solidarity ecosystem in terms of employment, residential space, network and social capital, age, cognitive and environmental aspects. This is senior-friendly healthcare business system aimed at meeting the senior needs for health life to enjoy active consumption culture life even after retirement, becoming a catalyst for minimizing generational conflicts, preventing the cognitive and physical deterioration of seniority in the areas of life healthcare, fitness and well-aging, and expanding into systems necessary for seniority self-reliance. We would like to draw up the development and requirements of the concept of the service platform for the study of collective characteristics for generation solidarity with senior class and the establishment of a customized senior health life system for generation solidarity. This system is characterized by a platform that can prevent the decline of seniors' cognitive and physical functions and enhance emotional stability. It is significant in providing feedback on the risk perception index, fall index, and prevention training index information to the child through the analysis and extraction of the senior health index for risk perception, fall probability, and fall prevention.

When utilizing a Tunnel Boring Machine (TBM) for tunnelling work, unexpected ground conditions can be encountered that are not predicted in the design stage. These include fractured zones or mixed ground conditions that are likely to reduce the stability of TBM excavation, and result in considerable economic losses such as construction delays or increases in costs. Minimizing these potential risks during tunnel construction is therefore a crucial issue in any mechanized tunneling project. This paper proposed the potential risk events that may occur due to risky ground conditions. A resistivity survey is utilized to predict the risky ground conditions ahead of the tunnel face during construction. The potential risk events are then evaluated based on their occurrence probability and impact. A TBM risk management system that can suggest proper solution methods (measures) for potential risk events is also developed. Multi-Criterion Decision Making (MCDM) is utilized to determine the optimal solution method (optimal measure) to handle risk events. Lastly, an actual construction site, at which there was a risk event during Earth Pressure-Balance (EPB) Shield TBM construction, is analyzed to verify the efficacy of the proposed system.

M&As are continuing to grow globally and are expected to increase in the future. With the fourth industrial revolution and the strengthening of neo-protection trade between countries, technology is cited as the core of national competitiveness, and the trend of M&A's increase, which is aimed at securing technology, is expected to continue. However, the risk of technology leakage, which is difficult to determine clearly illegally in the process of M&A, is still growing, and there is not enough prevention or response to this problem. the purpose of this paper was to divide the M&A process into seven stages and to ensure that important information of the enterprises during M&A between the countries and the domestic companies was not leaked unfairly, and each step analyzed the risk factors and causes of the leakage of important information in the M&A process and presented a risk-specific management plan for minimizing the leakage of important information based on the importance of the risk factors. Companies that pursue M&A in the future will reflect the M&A step-by-step risk and risk management measures derived based on case analysis and expert surveys. I hope to use risk management measures to help minimize unintentional leakage of important corporate information into the outside.

Background : Stomal recurrence that occasionally follows total laryngectomy is associated with very poor prognosis regardless of treatment modality, so it is very important to identify high risk patients to prevent stomal recurrence. Objectives : We attempted to select an optimal management method to prevent stomal recurrence by analyzing risk factors in each patient who was found to have stomal recurrence following total laryngectomy. Materials and Methods : Risk factors in each of eleven patients who had stomal recurrence out of 159 patients who underwent total laryngectomy in the last ten years were analyzed retrospectively. Data were gathered on risk factors such as the presence of subglottic extension, extralaryngeal extension, thyroid gland invasion, lymph node metastasis, timing of tracheotomy, tumor stage, postoperative radiotherapy, and inclusion of the stoma in the radiotherapy field. Results : There were eight cases of subglottic extension, six cases of extralaryngeal invasion, one case of pharyngocutaneous fistula that occurred as a postoperative complication, and one case who was taken completion laryngectomy following conservation surgery. With the exception of one case who was taken tracheotomy prior to total laryngectomy, all tracheotomies were performed intra-operatively after endotracheal intubation. There was no evidence of paratracheal lymph node or prelaryngeal lymph node metastasis on preoperative neck CT scan. There were six cases of T4 tumors, four cases of T3 tumors, and one case of T2 tumor. Salvage surgery was performed following radiotherapy in three cases, and aside from one case who was not taken post-operative radiotherapy, postoperative radiotherapy including the stoma was performed in the remaining seven cases within one month after surgery. Conclusion : Total laryngectomy with wide paratracheal lymph node dissection, thyroidectomy, and tracheotomy should be performed for patients who have high risk factors such as subglottic extension and advanced stage. We believe that tracheotomy should be precede endotracheal intubation. Efforts should be made to prevent stomal recurrence by utilizing postoperative radiotherapy and by minimizing postoperative complications such as infection and fistula.

Admixtures for concrete placed underwater have been developed to the stage that they are now widely used. The use of this type of product allows concrete to be placed underwater with far less risk than was previously possible. One of the problems facing users of underwater concreting admixtures is how does one test such products in order to access their performance initially while minimizing the expense of carrying out site trials. This paper will introduce three categories of laboratory test for underwater concrete listed next : fluidity test, non-segregation test, strength test. Trial underwater concretes were ordinary Portland cement. Strength and workability development and segregation resistance properties of the concrete under the coexistence of some kinds of superplasticizer were studied for this laboratory tests.

The clinical, investigative, and surgical experiences were reviewed in four patients with congenitally corrected transposition of the great arteries who presented to the National Medical Center between August 1983 and August 1985. This condition is very rare congenital anomaly defined as the combination of atrioventricular discordance and transposition of the great arteries. Examples of primitive [single] ventricle inverted [that is, left sided in situs solitus] with outflow chamber were excluded in this paper. According to the sequential arrangement of the hearts there were two cases of [S,L,L] and two cases of [I,D,D]. The surgical approach should be focused on minimizing the risk of heart block and increasing the degree of relief of pulmonary outflow tract obstruction [POTO]. We experienced complete heart block in two cases of [S,L,L] and significant residual POTO in one case of [S,L,L] and one case of [I,D,D] postoperatively. There were one hospital mortality caused by complete heart block and residual POTO and two delayed mortalities caused by congestive heart failure and sepsis respectively.
