Iron supplements such as ferrous sulfate tablets are usually used to treat iron-deficiency anemia in some elderly patients with primary neurologic disorders or decreased gag reflexes due to stroke, senile dementia, or parkinsonism. While the aspiration of ferrous sulfate is rarely reported, it is a potentially life-threatening condition that can lead to airway necrosis and bronchial stenosis. A detailed history and high suspicion of aspiration are required to avoid delays in diagnosis and treatment. The diagnosis can be confirmed by bronchoscopic examination and a tissue biopsy. Early removal of the aspirated tablet prevents acute complications, such as bronchial necrosis, hemoptysis, and lobar consolidation. Tablet removal is also necessary to prevent late bronchial stenosis. We presented the first case in Korea of a ferrous sulfate tablet aspiration that induced severe endobronchial inflammation.

Freshwater fish intake is a critical parameter for deriving water quality criteria and water quality standards for protection of human health based on human health risk assessment. Although the freshwater fish intake parameter should be accurate and representative of Korean fish consumption for the water quality criteria to be reliable, data are limited in Korea and have low reliability. In this study, Korean National Health and Nutrition Examination Survey data from 2008-2010 were analyzed to reevaluate freshwater fish consumption. Based on these results, an average consumption rate of 3.0 g/day per person, a $90^{th}$ percentile consumption rate of 0.0 g/day per person, an average consumption rate of 65.7 g/day per fish consumer, and a $90^{th}$ percentile consumption rate of 153.4 g/day per fish consumer were proposed for derivation of water quality criteria using a conservative approach and various exposure scenarios.

UCP 600 Article 14(b), providing rules for the period of the examination of documents, is a radical reorganization of UCP Article 13(b). The provision changes the period of time to a maximum of five banking days instead of reasonable time. One of the critical problems giving rise to the difficulty in interpretation and application is the question of fact that there may be two possible conflicting options in determining the time of checking documents presented. The one doctrine is fixed time(safe harbor) standard, and the other is hidden reasonableness standard. This study analyzes which option should be adopted for the optimal application standard by welfare effect methodology using consumer surplus approach and suggests that safe harbor standard should be optimal solution to the determination of period of examination of documents presented in letter of credit regime.

Biopsy is a critical method for disease diagnosis and treatment planning. It can be applied from simple inflammatory lesions to malignant tumors. But many general dental practitioners are unfamiliar with the basic knowledge and skills required for biopsy. Moreover, biopsy indications and contraindications for certain diseases may differ depending on the type of dental practice environment and the specialty of the dentist. Biopsy education can increase the choices a dentist has during disease diagnosis. Here we will discuss details on biopsy needed to the general dentist.

High temperature and high pressure heavy water flows through the pipes in atomic power plants. The curved parts of pipes are critical parts in that they change the direction of steam flow, and these parts are especially affected by severe wear. Therefore, most pipes in atomic power plants are tested by non-destructive examination by workers who use ultrasonic sensors to measure the wall thickness of pipes. But not only are these pipes located in a very dangerous environment, but the space is also very limited. For the safety of workers, it is necessary to design a device that uses a mobile robot that can inspect curved pipes. This paper presents the design and construction of a small device that can generate the necessary contact forces between ultrasonic sensors and pipe walls in a limited space. And a mobile robot is used in place ortho worker for successful non-destructive examination.

Fever of unknown origin (FUO) has been a convenient term used to classify patients who warrant a particular systemic approach to diagnostic evaluation and management. The greatest clinical concern in evaluating FUO is identifying patients whose fever has a serious or life-threatening cause when a delay in diagnosis could jeopardize successful intervention. Thorough history and complete physical examination are critical to uncover the etiologic diagnosis. Most cases of FUO in children are caused by atypical presentations of common diseases rather than by typical manifestations of rare disorders. Selection of diagnostic tests and speed of investigation should be guided by a knowledge of the disease severity, patient age, epidemiologic and geographic information, and any positive findings from a detailed history and physical examination. The three most common causes of FUO in children are infectious diseases, connective tissue diseases, and malignancy. In general, the prognosis of FUO in children is better than that of adults. Although the outcome is dependent on the primary disease process, fever abates spontaneously in most cases in whom the cause of fever remains unclear.

Male pseudohermaphrodites is one of abnormalities of phenotypic sex and have an XY chromosome constitution and testes, but the internal or external genitalia are to some degree those of a female. We surveyed one case which were referred in Veterinary Medical Teaching Hospital of Seoul National University. When patient was purchased, its phenotype was entirely female that have female external genitalia. However, from the age of 6 months, clitoris was gradually increased to Os clitoris, and patients showed male behavior. Critical clinical sign was trauma of protruded Os clitoris. In radiographic and ultrasonographic examination, he had normal vagina and urinary bladder. In chromosome examination, he had an XY chromosome constitution. This case was performed removal of Os clitoris and ovariohysterectomy.

Objectives The aim of this study is to investigate the possibility of making Korean Medicine-Western Medicine collaboration Critical Pathway for Acute Postoperative Pain after Back Surgery. Methods This preliminary Critical Pathway (CP) was composed of 9 Index of vertical axis (assesment, treatment, patient movements, consultation, diet, other, administration, examination, education) and 5 hospitalization periods of horizontal axis through a review of the literature and reference data of medical records. This preliminary CP's Content Validity Index (CVI) survey was carried out by 20 personnel of two different medical institutions from 06, June, 2016 to 15, June, 2016. All data were double-cross checked and analyzed. Results Of those questioned, there were 13 males and 7 females in age, 6 professors, 7 medical residents, 7 nurses in position of 20 personnel. According to the survey, among the 62 contents, 32 contents are above 80 percent agreements, 12 contents were between 70 to 80 percent and 18 contents below 70 percent agreements. Especially, Most contents in treatment index were below fixed validity. Overall Contents Validity in Index, Treatments (72.7%), Diet (100.0%), Other (100.0%), Administration (75.0%) and Examination (100.0%) were in high validity. On the other hands, Assessments (29.4%), Patient movements (0.0%), Consultation (30.0%) and Education (33.3%) were in low position. Conclusions This survey results can be evidence of possibility to develop New Korean Medicine-Western Medicine Collaboration Critical Pathway for Acute Postoperative Pain after Back Surgery.

본 연구는 임상실습 전 동료멘토링 학습을 적용한 OSCE프로그램(객관적 구조화 임상시험)을 실시하여 간호학생의 핵심기본간호술 자신감 및 비판적 사고성향에 미치는 효과를 파악하고자 수행하였다. 연구설계는 비동등성 대조군 전후실험설계의 실험연구로 연구대상은 J도 소재 일개 4년제 대학 간호학과 2학년 학생 68명이었으며 연구기간은 2016년 2월부터 2017년 2월까지였다. 연구결과 임상실습 전 동료 멘토링 학습을 적용한 OSCE프로그램(객관적 구조화 임상시험)이 핵심 기본간호술 수행자신감과 비판적 사고성향을 대조군에 비해 실험군이 유의하게 증가시켰고, 중재 후 핵심기본간호술 자신감과 비판적 사고성향 간에 긍정적 상관관계가 있는 것으로 나타났다. 따라서 임상실습 전 동료멘토링 학습을 적용한 OSCE프로그램이 간호학생의 핵심기본간호술 자신감과 비판적 사고성향을 향상시키는데 효과적이었으므로 이를 토대로 동료멘토링 학습을 적용한 OSCE프로그램의 효과를 비교분석하는 연구를 제언한다.
