Purpose: The objective of this study was to publicly report the hospital-level surgical volume for 7 types of surgery including gastrectomy. Also, to investigate the changes in patient behaviors after the public reporting among patients with gastrectomy. Methods: This study used data from the National Health Insurance Service Cohort. The data comprised of 2,214 patients who were diagnosed with gastric cancer and underwent gastrectomy during 2004-2012. An interrupted time series analysis was performed to investigate the association between patients' choice and public reporting. Results: 79.27% of the patients visited a hospital with high surgical volume. The time trend after introduction of public reporting was positively associated with visiting a high volume hospital (per 1 month, RR: 1.004, p=0.0329). However, after adjusting the health policies by reducing copayment, public reporting on surgical volume was not associated with visiting a high volume hospital. Sub-group analyses had also similar results. Conclusion: Patients were more affected by policies on economic support than on public reporting, and the changes in treatment options may have been affected by the increasing preference for large size hospitals. Thus, public reporting did not significantly improve the options available for patients and their decision making on health care utilization.

We are reporting a case of esophageal hemangioma, which is a very rare disease with only 24 cases having been reported. A 31-year-old male with dysphagia was shown to have a hemangioma of the upper thoracic esophagus and resection of the lesion cured this problem. Once diagnosed in symptomatic patient, treatment should be instituted because of followings; 1. growth potency to large size, 2. possible complications such as hemorrhage and obstruction, and 3. exclusion diagnosis of malignancy. Surgery is the treatment of choice due to its effectiveness and safety, but endoscopic removal may be possible for small tumors and those on a pedicle.

Ankylosis of the temporomandibular joint (TMJ) is a disabling disease resulting from fibrous or bony fusion of the mandibular condyle and the glenoid fossa. Early diagnosis and surgical treatment are essential to prevent facial deformity and other complications. Conventional radiography has limitations in demonstrating the true extent of ankylosis. It is important for surgeons to be aware of the size and degree of bony ankylosis in order to perform complete resection of the ankylotic mass. In addition, a detailed evaluation of the relationship with adjacent vital structures such as the internal maxillary artery, inferior alveolar nerve canal, external auditory canal, and skull base are crucial to avoid iatrogenic injury. Multidetector computed tomography (MDCT) is the current imaging modality of choice for preoperative assessments. Herein, the authors propose a structured CT reporting template for TMJ ankylosis to strengthen the value of the preoperative imaging report and to reduce the rates of intraoperative complications and recurrence.

The Building and Construction Industry Security of Payment Act 1999 (NSW) (the NSW Act) is a unique form of statutory regulation for the building and construction industry, which gives virtually all industry participants a statutory right to, and a means of recovering, payments for work done under a construction contract. The research aim is to examine current trends in adjudication applications and determinations under the NSW Act. The data used for this study was the collected by the NSW Office of Finance & Services as part of a regular reporting regime for the period from 1 July 2013 and ending on 30 June 2014. With just over 817 adjudication applications having been made over the 2013/14 period, the data indicates that adjudication is being frequently utilized by stakeholders in the NSW building and construction industry as a means of progress payment recovery. Adjudication is proving to be a popular choice for those making claims of less than AU$250,000. Claimants were awarded about 36% of the total of claimed amounts and claimants are generally successful at adjudication in terms of the proportion of the claimed amounts determined in their favour. This is particularly so in relation to claims of less than $100,000, which represents about 70% of the total applications made over the reporting period. The data indicates that adjudication fees are generally modest enough to conclude that adjudication provides claimants across all claim ranges with a relatively inexpensive means of having disputed progress payments determined by an independent adjudicator.

본 논문의 목적은 한국과 일본의 제조기업들을 대상으로 경영자의 회계선택이 비대칭적 원가행태에 어떠한 영향을 미치는지를 분석하는 것이다. 해당 내용을 분석하기 위하여 Shust and Weiss(2014)가 제안한 경제적원가 대용치인 현금영업원가(OC)와 감가상각 전 영업비용(OEBD)을 이용하여 기존연구들의 분석대상이었던 판매관리비, 매출원가, 영업비용과의 원가행태 차별성을 분석하였다. 분석결과 첫째, 영업비용과 현금영업원가의 원가행태간에 차별성이 한일 양국 모두 나타났다. 구체적으로는 영업비용에 비하여 현금영업원가의 하방경직성 정도가 더 높게 나타났다. 특히 한국 기업은 유형고정자산집중도가 높을수록 일본 기업에 비하여 하방경직성이 약화되는 것으로 나타났다. 둘째, 감가상각비의 발생은 한일 양국 모두 원가의 하방경직성을 약화시키는 것으로 나타났다. 또한 한국과 일본의 제조 기업은 시차를 두고 상관성을 가지고 있는 것으로 분석되었으며, 향후 양국의 기업을 분석 및 연구하는데 유용한 지침을 제공할 수 있을 것이다. 그리고 일본기업의 경우 부채비율이 높을수록 원가절감을 보다 적극적으로 하는 것으로 나타났다. 저자들은 한일관계가 냉각된 현 시점에 학계차원에서 본 연구를 통하여 양국 간의 관계 개선에 도움이 되길 기대한다.

This paper describes that invasive aspergillosis was found in oral cavity, especially in lower molar periodontium in a immunocompromised 34-year-old woman who had been admitted in hemato-oncology with the diagnosis of acute myeloid leukemia. Antifungal therapy and surgical excision of involved teeth, bone and gingiva were the treatment of choice. After treatment infected area was healed very well. We would like to report our case because we could not find any paper reporting on invasive aspergillosis occurring in lower molar periodontium.

In an attempt to fabricate all inclusive display systems we are presenting a study on several elements that would be used as building blocks for all-on-board integrated applications on stainless steel foils. These systems would include in the same substrate all or many of the components needed to drive a flat panel OLED display. We are reporting results on both digital and analog circuits on stainless steel foils. Shift registers running at speeds greater than 1.0MHz are shown as well as oscillators operating at over 40MHz. Pixel circuits for driving organic light emitting diodes are presented. The device technology of choice is that based on poly-silicon TFT technology as it has the potential of producing circuits with good performance and considerable cost savings over the established processes on quartz or glass substrates (amorphous Silicon a-Si:H or silicon on Insulator SOI).

More donors are formally assessing their multilateral aid disbursement policies as well as the multilateral institutions that they contribute to. Analyzing OECD Creditor Reporting System data from 2011 to 2019 of 23 donors and 34 multilateral organizations, we find evidence of institutional portfolio building of donors to align multilateral and bilateral aid channels. Such tendency is more pronounced for core-funding than multi-bi funding and much stronger at the recipient country level than at the sectoral level. Smaller donors that operate from a limited multilateral budget show greater preferences for geographical similarity. When donors give to institutions with sectoral specialization, they seek sectoral similarity with their bilateral aid.

In the past, there has not been a law with the main purpose of preventing or preventing a risk in advance in order to protect the safety of patients in relation to medical services. It is evaluated that the enactment of the Patient Safety Act has a very important meaning in protecting patient safety as the top priority and further improving the quality of medical care. However, looking at the status of patient safety accidents reported to the Patient Safety Reporting System after the Patient Safety Act was enacted and implemented, various types of risk factors for patient safety still exist in the medical field. Meanwhile, Korea Consumer Agency and Korea Medical Dispute Mediation and Arbitration Agency, the existing domestic ADR specialized agencies, have been operating reasonable damage relief procedures such as recommendation of settlement, mediation, and arbitration according to the purpose of their establishment. Therefore, with the aimof broadening the choice of compensation system for patients, we propose the establishment and revision of ADR-related laws to apply the damage relief procedures of both institutions.
