The purpose of this study was to analyze the job of Head hospital coordinators based on the DACUM(Developing A Curriculum) method. The contents of this study were to extract the duties, tasks and performance standards consisting of the job of a Head hospital coordinator and to investigate levels of importance, difficulties, frequency and entry level on each task, and to make out a job model of Head hospital coordinators. A DACUM committee(seven members) was composed to analyze the job of Head hospital coordinators and the committee members were totally nine : a facilitator, seven Head hospital coordinators and a recorder. This study was conducted in Seoul and Gyeonggi Province from August to December, 2015. The major findings of this study were as follows; first, a Head hospital coordinator is defined to be an expert to create values and culture of a hospital, plan and manage hospital's efficient management methods to maximize customer satisfaction and improve the management of a hospital. Second, the job of Head hospital coordinators was categorized into total nine duties and sixty eight tasks. Third, duties in the job of Head hospital coordinators were classified into organization of medical management planning, medical management analysis, medical service quality management, hospital marketing, hospital customer management, hospital human resource management, hospital organization management, hospital financial management and self development.

Due to increased interest in safety in sports, leisure, industries, and daily life; the demand for products that protect the head is increasing. As a preparatory study for the development of head protection for head injury prevention, this study analyzed patents and utility models related to head protection products such as industrial safety helmets, vehicle helmets, and sports protection gear. For this study, 368 patents and utility models for head protection products searched through WipsOn were selected and analyzed by application year, function, application, protection area, main material, and subject. From the analytic results of this study, the quantitative and qualitative flow and characteristics of developing technology related to head protection products were identified. Through the trend of current technology, it provided data to seek the development direction in the future. The significance of this study is to secure objective data to establish a road map for creating new Intellectual Property for head protection products.

Head and neck cancer is the sixth most common type of human cancer worldwide. Squamous cell carcinoma is the most common cancer of the head and neck. Since $^{18}F-FDG$ PET is very sensitive to detecting squamous cell carcinoma, it has been widely used in patients with head and neck cancers for initial staging, management of recurrent cancers, and therapeutic monitoring. According to clinical research data, $^{18}F-FDG$ PET is expected to be a very helpful diagnostic tool in the management of head and neck cancer.

Benign lymphoepithelial cysts of parotid gland were first described by Miculicz in 1888, have been presented for a long time, uncommonly. But, recently it has been reported with increasing frequency since the onset of human immunodeficiency virus (HIV) infection. Benign lymphoepithelial cysts can be diagnosed by the fine needle aspiration in conjunction with the history and physical examination. The therapeutic options of benign lymphoepithelial cysts have been limited to aspiration, surgical resection, medical therapy, radiotherapy and sclerotherapy. Recently, we experienced a case of benign lymphoepithelial cyst of right parotid gland, so we report this case with review of the literatures.

This study analyzed the changes in carbon monoxide, carbon dioxide, oxygen and visual distance by presence of sprinkler heads and their types in the event of a fire in an indoor gymnasium. Based on carbon monoxide and visual distance that affects human bodies enormously, first, if there is no sprinkler head, carbon monoxide will reach 0.4% within five seconds and visual distance rapidly shrank within five seconds. Seconds, in the event of standard sprinkler heads, carbon monoxide gradually increased from 30 seconds onwards and visual distance rapidly shrank after five seconds. Second, Third, if there are special sprinkler heads, carbon monoxide fluctuated after opening the head and visual distance became 5m or below from 15 seconds. Finally, in the event of early response sprinkler heads, carbon monoxide fluctuated up and down at 3 seconds due to falling water drops. Visual distance shrank up to 5m or below at 6 seconds. In the future, time for operation of each sprinkler head shall be analyzed.

Background and Objectives: Globally, the human immunodeficiency virus (HIV) is responsible for one of the most serious pandemics to date. The vulnerability of the vestibular system in individuals with HIV has been confirmed, and central vestibular impairments have been frequently reported. However, there are disagreements on the impact of HIV on peripheral vestibular function. Thus, the current study aimed to determine the prevalence of peripheral vestibular impairment, specifically related to the semi-circular canals (SCCs), in HIV-positive individuals receiving antiretroviral (ARV) treatment. Subjects and Methods: A total of 92 adults between the ages of 18 and 50 years (divided into two groups) participated in the study. The first group comprised HIV-positive individuals receiving ARV treatment (n₁=60), and the second group comprised HIV-negative participants (n₂=32). The video head impulse test was used to conduct the head impulse paradigm (HIMP). Results: Bilateral normal HIMP results were obtained in 95% of the HIV-positive participants and all HIV-negative participants. The gain of the left posterior SCCs was significantly lower in the HIV-positive group, while the gains of all other canals between the two groups were comparable. Conclusions: The prevalence of peripheral vestibular impairment in the HIV-positive group was not significantly different from that of the HIV-negative group. The reduced prevalence in the current study may be attributed to participant characteristics, the test battery employed, and the central compensation of the vestibular dysfunctions at the later stages of infection.

This paper propose a framework for human body parts in RGB-D image. We conduct tasks of obtaining person area, finding candidate areas and local detection in order to detect hand, foot and head which have features of long accumulative geodesic distance. A person area is obtained with background subtraction and noise removal by using depth image which is robust to illumination change. Finding candidate areas performs construction of graph model which allows us to measure accumulative geodesic distance for the candidates. Instead of raw depth map, our approach constructs graph model with segmented regions by quadtree structure to improve searching time for the candidates. Local detection uses HOG based SVM for each parts, and head is detected for the first time. To minimize false detections for hand and foot parts, the candidates are classified with upper or lower body using the head position and properties of geodesic distance. Then, detect hand and foot with the local detectors. We evaluate our algorithm with datasets collected Kinect v2 sensor, and our approach shows good performance for head, hand and foot detection.
