A STUDY ON USERS’ AWARENESS OF MOVING-PICTURE ADS IN MOVINF-PICTURE CONTENTS WITH DIFFERENT ONLINE MEDIA CHARATERISTICS

Internet plays an important role in our lives and the number of internet users keeps increasing. As internet users are exposed to ads from online media while not knowing, advertising market’s interest in moving-picture ads increases. Thus, this study comparatively measured effects of moving-picture ads inserted in news-related moving-picture contents of media companies and those of moving-picture ads inserted in moving-picture contents of professional moving-picture UCC. Advertising effects were compared between media characteristics (news and UCC) and keyword relatedness (related or unrelated keyword) and interactions of the two factors were measured. As a result, there was a significant difference in media characteristics and keyword relatedness. As for media characteristics, advertising effects of news-related moving pictures were higher than those of professional moving-picture UCC in all items. As for keyword relatedness, executing ads of keyword related to moving-picture contents was verified to have higher advertising effects than executing ads of unrelated keywords. There was no significant difference in interactions between these two factors. As interest in the moving picture advertising market increases, the necessity to introduce a method to analyze effects of moving-picture ads is raised. As for evaluation of advertising effects of moving pictures of media companies, the theme to be dealt in this paper, it is still difficult to state that moving-picture ads are facilitated in the overall market of moving picture services. So under such circumstances that verification is hard to achieve, the attempt of this study is considered to be meaningful. Keyword: media companies, UCC, moving-picture contents, moving-picture ads, advertising effects, media, new

Crack-Resistance Behavior of an Encapsulated, Healing Agent Embedded Buffer Layer on Self-Healing Thermal Barrier Coatings

In this work, a novel thermal barrier coating (TBC) system is proposed that embeds silicon particles in coating as a crack-healing agent. The healing agent is encapsulated to avoid unintended reactions and premature oxidation. Thermal durability of the developed TBCs is evaluated through cyclic thermal fatigue and jet engine thermal shock tests. Moreover, artificial cracks are introduced into the buffer layer’s cross section using a microhardness indentation method. Then, the indented TBC specimens are subject to heat treatment to investigate their crack-resisting behavior in detail. The TBC specimens with the embedded healing agents exhibit a relatively better thermal fatigue resistance than the conventional TBCs. The encapsulated healing agent protects rapid large crack openings under thermal shock conditions. Different crack-resisting behaviors and mechanisms are proposed depending on the embedding healing agents

Crack-Growth Behavior in Thermal Barrier Coatings with Cyclic Thermal Exposure

Crack-growth behavior in yttria-stabilized zirconia-based thermal barrier coatings (TBCs) is investigated through a cyclic thermal fatigue (CTF) test to understand TBCs’ failure mechanisms. Initial cracks were introduced on the coatings’ top surface and cross section using the micro-indentation technique. The results show that crack length in the surface-cracked TBCs grew parabolically with the number of cycles in the CTF test. Failure in the surface-cracked TBC was dependent on the initial crack length formed with different loading levels, suggesting the existence of a threshold surface crack length. For the cross section, the horizontal crack length increased in a similar manner as observed in the surface. By contrast, in the vertical direction, the crack did not grow very much with CTF testing. An analytical model is proposed to explain the experimentally-observed crack-growth behavior

The Utilization of Traditional Herbal Medicine for Treatment in Traditional Korean Medicine Clinics

A cross-sectional study has been conducted to detect the facts about the use of traditional herbal medicines (THMs) in South Korea. The questionnaire has been adopted from the 2017 National Survey for the usage of traditional Korean medicine (TKM) and consumption of THMs. A total number of 1346 participants have been involved in this study. Results showed that the non-decoction types of herbal medicines, which are mostly used for therapeutic purposes (89.0%), and the decoction types of herbal medicines were not only used for the purpose of treatment of diseases (62.5%) but also health improvement purposes (21.9%). Results presented that decoction types of THMs are used for musculoskeletal diseases (56.0%), digestive diseases (21.3%), and respiratory diseases (6.3%), whereas the non-decoction types of THMs are commonly used in musculoskeletal diseases (55.6%), respiratory diseases (20.5%), and digestive diseases (18.1%). Future studies are highly recommended to detect more details about the medical use of THMs in South Korea

The limited immunomodulatory effects of escharectomy on the kinetics of endotoxin, cytokines, and adhesion molecules in major burns.

Escharectomy has been shown to improve the survival rates and the outcomes in burns. This observational study was conducted to assess the role of escharectomy on the inflammatory mediators in major burns. Seventeen ASA physical status II or status III adult surviving major burn patients were recruited. When the escharectomy was scheduled, a series of blood samples was obtained at -3 and -1 days preoperation, and +1 and +3 postoperation. The changing levels of endotoxin, cytokines, and adhesion molecules were measured with a quantitative sandwich immunoassay. Extensive escharectomy did not appear to have any significant impact on the levels of tumor necrosis factor alpha, interleukin-10, soluble intracellular adhesion molecule-1 and soluble vascular adhesion molecule-1. Meanwhile, endotoxin and E-selectin were significantly decreased after escharectomy. Escharectomy appeared to have a limited immunomodulatory effect on the inflammatory mediators in systemic inflammatory responses induced by major burns. This is probably related to the timing and extent of surgery, and the complex nature of burn-related inflammation

Case of seropositive allergic bronchopulmonary aspergillosis in a 10-year-old girl without previously documented asthma

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity lung disease due to bronchial colonization of Aspergillus fumigatus that occurs in susceptible patients with asthma or cystic fibrosis. A 10-year-old girl was referred to the Department of Pediatric Pulmonology for persistent consolidations on chest radiography. Pulmonary consolidations were observed in the right upper and left lower lobes and were not resolved with a 4-week prescription of broad-spectrum antibiotics. The patient had a history of atopic dermatitis and allergic rhinitis but no history of asthma. She had no fever but produced thick and greenish sputum. Her breathing sounds were clear. On laboratory testing, her total blood eosinophil count was 1,412/mm3 and total serum IgE level was 2,200 kU/L. Aspergillus was isolated in the sputum culture. The A. fumigatus-specific IgE level was 15.4 kU/L, and the Aspergillus antibody test was also positive. A chest computed tomography scan demonstrated bronchial wall thickening and consolidation without bronchiectasis. An antifungal agent was added but resulted in no improvement of pulmonary consolidations after 3 weeks. Pulmonary function test was normal. Methacholine provocation test was performed, revealing bronchial hyperreactivity (PC20=5.31 mg/mL). Although the patient had no history of asthma or bronchiectasis, ABPA-seropositivity was suspected. Oral prednisolone (1 mg/kg/day) combined with antifungal therapy was started. Pulmonary consolidations began decreasing after 1 week of treatment and completely resolved after 1 month. This is the first observed and treated case of seropositive ABPA in Korean children without previously documented asthma
