This paper analyzes quality management of aviation safety services in Korea and proposes practical implications for improvement. We look into how quality management is conducted in the Korean aviation industry and confirm aviation authority's efforts for a quality management system. We also compare and analyze international standard ISO 9001 and aviation safety oversight system quality management cases of International Civil Aviation Organization (ICAO) and U.S. Federal Aviation Administration (FAA) with a Korean case. Results find the difference in defining the scope of ISO 9001 management between ICAO/FAA and the Korean authority which causes unnecessary misunderstanding in oversight perception. The Korean aviation authority strives to provide a high level of safety oversight services by educating aviation safety inspectors as well as establishing a quality management system. We believe that our proposals can help Korean aviation safety oversight system secure objective credibility and seek a safe growth and development of the aviation industry.

Purpose: Thisstudy aimsto analyze the distribution of audit committee, independent board of commissioners, and institutional ownership on earnings quality with strengthening earnings growth. Research Design data and Methodology: This quantitative research uses a comparative causal approach. The research population consists of manufacturing companies in the basic and chemical industry sector listed on the Indonesia Stock Exchange in 2016-2022. Samples were obtained as many as 112 using purposive sampling method. The analysis technique to test the hypothesis uses multiple linear regression tests and moderation tests with an absolute difference approach. Results: The results showed that the audit committee and board of commissioners provide a significant positive distribution on earnings quality, while institutional ownership provides a significant negative distribution on earnings quality. Earnings growth strengthens the distribution of the audit committee and independent board of commissioners on earnings quality. However, earnings growth does not strengthen the distribution of institutional ownership on earnings quality. Conclusions: Audit oversight from audit committee and management performance oversight from the independent board of commissioners improves the credibility of earnings quality. Management oversight from institutional ownership reduces earnings quality. The interaction of earnings growth with maximum supervision can improve earnings quality, except for supervision from institutional ownership.

This study aims at finding issues and ideas of waterfront planning through analysing planning concepts and characteristics of New York City Waterfront Comprehensive Plan(NYC WCP). The first NYC WCP in 1992 divided waterfront area as 4 functional areas which are natural, public, working and redeveloping waterfront. The characteristics of WCP in 1992 are zonning, height, setback, public access, visual corridor, floor area and so forth. After then NYC WCP revision in 2011 intergrated and developed the former plan through the eight visions which are expanding public access, enlivening the waterfront, improving water quality, restoring the natural waterfront, enhancing the Blue Network, improving government oversight and increasing climate resillience. In conclusion, NYC WCP successfully achieved both sufficient capacity of planning concepts and design guidelines for each region.

With the escalating prevalence of modular construction projects, there is a concurrent surge in scholarly and industrial intrigue in this domain, leading to a broadened spectrum of its applications. Modular construction, inherently facilitated by controlled factory settings, boasts the capability to consistently deliver edifices of superior quality. To optimize this advantage, the judicious integration of quality assurance methodologies during the site-specific phases of lifting and assembly is non-negotiable. This research embarked on a survey directed at project stakeholders, aiming to gauge the perceived significance and efficaciousness of prevailing quality preservation and oversight protocols during the aforementioned site stages, subsequently employing the Importance-Performance Analysis(IPA) for data interpretation. The findings elucidated that, while a majority of quality assurance procedures were adeptly executed, perceptual disparities existed among stakeholders regarding certain aspects, prompting recommendations for enhancement. This investigative endeavor lays a foundation, aiding future studies in amplifying the quality assurance cognizance among professionals during modular construction's site-assembly phase.

Credit rating agencies(CRAs) are accused of failing to provide accurate and fair credit ratings and hence being responsible for the crisis. This paper tries to add on to the literature on credit rating reform through examining the CRAs in a model where rating quality is unobservable. We show that unobservability of rating effort results in the sub-optimal level of quality. Then the paper extends the model to incorporate ancillary services, competition and reputation. We show that ancillary services worsen the conflict of interests of the CRAs and that competition and reputation may not be strong enough to discipline the CRAs. Hence regulatory oversight and imposition of liability may be necessary in order to increase the accuracy of ratings.

Purpose - This article accentuates that there is pervasive corruption in the supply chain and procurement of goods and services in the South African public sector, particularly in the local sphere of government. Consequently, the poor and the indigents who are supposed to receive quality services are affected. Therefore, the article emphasizes the need to strengthen compliance in the supply chain and procurement processes in order to combat corruption. Research design, data, and methodology - This article extensively utilized qualitative literature review approach to address and solve the problem of endemic corruption in the supply chain and procurement being perpetrated by local government officials. Results - The synthesis shows that by strengthening compliance of supply chain and procurement strategies, measures and frameworks, the likelihood of corruption will be drastically reduced if not totally eradicated. It demonstrates that the poor and the indigents who are supposed to receive quality services are being denied due to corruption. It also shows that failure to comply should result to enforcement of punitive sanctions against perpetrators. Conclusions - This study indicates that effective and efficient implementation of supply chain and procurement strategies, measures and frameworks are panacea for curbing corruption in South Africa public sector especially at the local sphere of government.

PCAOB conducts the direct supervision for the PCAOB registered accounting firm. Therefore, if an accounting firm is registered with the PCAOB, it will thoroughly manage for their quality management systems. The registered auditor can be expected to have better quality of the audit. This study carried out the analysis using the audit fee which proxies for audit quality. The results of analysis are as follows. After controlling for foreign accounting firms affiliated status, company size, risky assets, leverage, ROA, and market-related variables, PCAOB is a significant explanatory variable for the audit fees. The results of this study support the hypothesis that PCAOB-registered auditors will provide a good audit quality.

Variation in construction means modification of design, changes in quality, quantity of work including the alteration of standard of materials or goods to be used in the work and the removal from site any kind of material not in accordance in the contract. In Ghana, Variation order has become major issue in the construction industry. This had resulted in cost overruns, delay and in some contracts dispute, between parties. The aim of this paper was to identify the root causes of variation; effects of variations on projects in Ghana and the means of reducing the impact of variation order. The method of the study involved literature review, primary data collection, interview and closed - ended- questionnaires. Mean Scores Method was used to rank the identified factors causing variation. Analysis Of Variance Test was use to test for the significant difference between means among the professional groups. The study revealed that most causes of variation were change of design by client and inadequate working details. Establishment of oversight project management committee and flow of information were identified as means of controlling variations during project administration.

We use a novel, forced censoring technique that closer fits the lower tails of strenth distributions to better estimate extremly smaller percentiles for measuring progress in continuous improvement initiatives. These percentiles are of greater interest for companies, government oversight organizations, and consumers concerned with safely and preventing accidents for many products in general, but specifically for medium density fiberboard (MDF). The international industrial standard for MDF for measuring highest quality is internal bond (IB, also called tensile strengh) and its smaller percentiles are crucial, especially the first percentile and lower ones. We induce censoring at a value just above the median to weight lower observations more. Using this approach, we have better fits in the lower tails of the distribution, where these samller percentiles are impacted most. Finally, bootstrap estimates of the small percentiles are used to demonstrate improved intervals by our forced censoring approach and the fitted model. There was evidence from the study to suggest that MDF has potentially different failure modes for early failures. Overall, our approach is parsimonious and is suitable for real time manufacturing settings. The approach works for either strengths distributions or lifetime distributions.

The adjustment in guidelines for quality certification of recycled aggregate permitted the Quality Control Manager of a company specializing in recycled aggregate quality certification to concurrently assume the role of Environmental Management Manager. Analysis of the outcomes from the 2023 recycled aggregate quality certification follow-up management audit conducted by the certification agency revealed that in 95 out of 242 cases, constituting approximately 39% of the total cases, individuals held concurrent positions. Following the regulatory revision, there has been a notable proliferation of concurrent roles across various enterprises. Concerns arose regarding the potential neglect of quality control for certified recycled aggregates in comparison to scenarios where individuals are solely responsible for specific duties related to quality and environmental management. Audit results encompassing six aspects, including waste management, were evaluated on a scale of 6 points. A comparative analysis was conducted between the outcomes of 147 cases managed by dedicated personnel, as previously practiced, and 95 cases managed by individuals with concurrent roles. Although the average score of the latter group was marginally lower, no statistically significant disparity was observed between the two groups. Consequently, apprehensions regarding the oversight of quality control stemming from the allowance of concurrent roles appear unfounded. Within the context of recent regulatory revisions, permitting concurrent roles in managerial capacities is deemed an appropriate relaxation of regulations.
