Delirium is a common symptom in patients with terminal cancer. The prevalence increases in the dying phase. Delirium causes negative effects on quality of life for both patients and their families, and is associated with higher mortality. However, some studies reported that it tends to remain unrecognized in palliative care setting. That may be related with difficulties to distinguish the symptom from others with overlapping characteristics such as depression and dementia, and a lack of knowledge regarding assessment and diagnostic tools. We suggest that accurate recognition with validated tools and early diagnosis of the symptom should be highly prioritized in delirium management in palliative care setting. After diagnosing delirium, it is important to identify and address reversible precipitants such as medication, dehydration, and infection. Non-pharmacological interventions including comfortable environment for the patient and family education are also essential in the management strategy. If such interventions prove ineffective or insufficient to control hyperactive symptoms, pharmacologic interventions with antipsychotics and benzodiazepine can be considered. Until now, low levels of haloperidol remains the standard treatment despite a lack of evidence. Atypical antipsychotics such as olanzapine, quetiapine and risperidone reportedly have similar efficacy with a stronger sedating property and less adverse effect compared to haloperidol. Currently, delirium medications that can be used in palliative care setting require more clinical trials, and thus, clinical guidelines are not sufficiently available. We suggest that it is warranted to develop clinical guidelines based on well-designed clinical studies for palliative care patients.

The general tendency of approach to Korean Design History has been focusing its primary interest on the grand story in relation to the problems of modernization in political, economical and social aspects of Korea. In the discourse of modernization, however, there are two sides immanent in the modernization: there is the formal, institutional and authoritative modernization developed inside the capitalistic mode of production and the informal, individual and cultural modernization manifested in the mode of everyday lives. Especially, despite the viewpoint of the latter being embossed as an alternative approach in various areas including the academic world of history since the collapse of socialism, the historical recognition of the phenomena of modern design by the Korean design historians is more like the 'history from the above' that exists at the level of the discourse outside the reality rather than the 'history from the below' that exists within the ordinary life. To grant a sense of balance in such frame of historical understanding, it requires the restructuring the design history of Korea through the cultural perspectives from having the representation of mundane lives realized by the voluntary design activity of the common people as research subjects. One of the methods to acquire an answer to such problem is decoding, in the manner of 'cultural history', the life-long domestic artifact made by Madame Yang, Gap Jo (currently 87 years of age) who is a model of typical Korean mother. Through the historical rumination on the traces of unpretentious lives of the people that has been buried under the grand narrative of the Korean Design History, a new era aimed for the historical prospect of Korean design as cultural history will be possible by excavating the petit yet multi-layered meaning of Korean designs.

In this study, the health insurance application of PET and the change in the pay standard were examined, and the amount of health insurance use over the past 10 years was analyzed. Positron tomography was applied as health insurance in 2006, and after ¹⁸F-FDG was first applied as health insurance, positron tomography tests using various radioactive isotopes have been applied as health insurance. As of 2019, the number of positron emission tomography tests was 198,651 cases, and the treatment amount was about 88.3 billion won, and the number of tests according to general characteristics was higher in men than in women, and by age, the number of tests was the highest in 60s. The number of outpatient examinations was higher than that of inpatient examinations, and the number of examinations in tertiary hospitals(68.2%) was significantly higher than that of general hospitals and hospitals. As for the test site, torso test was the most common at 86.6%, and radioisotope was the most at 93.6% using ¹⁸F-FDG. The change in the use of PET for 10 years increased steadily from 2010 to 2014, but the amount of use decreased sharply afterwards as the recognition of asymptomatic long-term follow-up tests was deleted due to the government's change in health insurance application standards in 2014. As changes in health insurance standards have a great influence on changes in health insurance usage, continuous monitoring will be required in the future.

In this paper, we propose a low-cost and compact motion capture system which enables to play motion games in PS2(Play Station 2). Recently, motion capture systems which are being used as a part in film producing and making games are too expensive and enormous systems. Now days, motion games using common USB camera are slow and have two-dimension recognition. But PSD sensor has a few good points, such as fast and low-cost. In recently year, 3D motion capture systems using 2D PSD (Position Sensitive Detector) optic sensor for motion capturing have been developed. One is Multi-PSD motion capture system applying stereo vision and another is Single-PSD motion capture system applying optical theory ship. But there are some problems to apply them to motion games. The Multi-PSD is high-cost and complicated because of using two more PSD Camera. It is so difficult to make markers having omni-direction equal intensity in Single-PSD. In this research, we propose a new theory that solves aforementioned problems. It can measure 3D coordination if separated two marker's intensity is equal to. We made a system based on this theory and experimented for performance capability. As a result, we were able to develop a motion capture system which is a single, low-cost, fast, compact, wide-angle and an adaptable motion games. The developed system is expected to be useful in animation, movies and games.

The concept of food coordination was introduced at the end of the 1990s and has generated a great deal of interest until now. However, no standard for the classification of such studies has been established yet. This study was conducted to examine the trends in food coordination studies published from 2000 to 2008. To accomplish this, approximately 335 food coordination articles were reviewed. Classification based on content analysis and the document review were conducted based on study themes(subjects), study forms, study designs, places of application, survey area and sample types. The most important type of study identified in this review was study themes. The themes of the study were divided into the following 10 subjects: 1) studies on the definition and recognition of food coordination, 2) studies on the environment, 3) studies on colors and package designs, 4) studies on table setting, table manner and etiquette, 5) studies on photography, editorial design, identity design and menu, 6) studies on components of dining atmosphere display and table/glass ware, 7) studies on emotions and sensibility, the five senses and food coordination, 8) studies on human resources, 9) studies on reviews, food & culture and education, 10) studies on purchasing, consumer behavior and marketing. The most common subjects were the components of dining atmosphere display and table/glass ware(23.6%). In addition, 17% of the articles reviewed were conducted to study colors and package designs, 14.6% to evaluate purchasing and consumer behavior and marketing, 13.4% to evaluate the environment, and 9.6% to study food & culture and education. Overall, these five subjects accounted for more than 75% of the articles reviewed.

It has been reported that plasma membrane activity of the spermatozoa may be susceptible to be influenced by extracellular osmolality and such membranous changes involve infracellular molecular changes, special regard to the structure of membranous lipids, and the accompanying ion-channel of which are closely related with their fluidity of $Ca^{2+}$ and HCO$^{-}_{3}$. It is of common recognition that a certain kind of sterol acceptor player an important to induce lipid fluctuation of the sperm plasma membrane which have been influenced by BSA administration and came in effect to outflow of cholesterol from the spermatozoa and resulted in changes of ionic fluidity to facilitate adenylyl cyclase, and to induce protein tyrosine phosphorylation by increase of cAMP and activation of PKA. Thus it seems likely that an augmentation of the acrosomal reaction is closely related with protein tyrosine phosphorylation. The following experimental results were obtained in the present study; Under the high osmolality conditions, the spermatozoa motility declined significantly and the structural change of the plasma membrane diminished to confirm that the response degrees to the osmolality depended upon the water transfer volume through the plasma membrane and the changes of cellular volume. Those experimental results suggest that a physiological parameter such as low temperature condition played an important role for presentation of spermatozoa and that inducement of spermatozoa activation for reinforcement of protein tyrosine phosphorylation. On the other hand, it seemed likely that the BSA administration as one of sterol accepters might represent a key role also under the high osmolality condition and their result also suggests that osmolality change, special regard to high osmolality condition may play an important role also in the processes of signal transmission.

Construction Management(CM) and Building Information Management(BIM) have a lot in common that they need to establish a cooperation system among different disciplines and promote smooth communication among project stakeholders throughout the project life-cycle. BIM can be an effective information management tool for CM's business and improve their service value. However, BIM uses by Construction Managers(CMr) are very limited. The objective of this study is to analyze the intention of CMrs to adopt BIM and establish effective BIM use strategy in the CMr's point of view. This study utilizes Technology Acceptance Model(TAM) as a research method, and the results show that 1) CMrs think it is more important whether BIM is required to be adopted in their business process at the social or industry level than that BIM can improve their personal competence, recognition, and impressions through their voluntary BIM adoption; 2) that CMrs think it is important to figure out business processes where BIM can be smoothly incorporated; and 3) that CMrs hesitate the use and trial of BIM in their realworld business although they agree that BIM needs to be eventually adopted in their business in the future. Based on these results, directions for establish a strategy for BIM adoption were proposed at the CMr's point of view

The purpose of this study was to examine the influence of type of malocclusion and orthodontic treatment awareness on quality of life among orthodontic patients in the region of Busan as well as to develop an educational program tailored to the type of malocclusion as a way to improve quality of life. A survey was conducted for approximately 6 months from December, 2015, and the answer sheets from 472 respondents were analyzed. The most common painful area was the teeth, and this case was most predominant in the respondents with level 2 malocclusion, who differed from others in that regard (p<0.001). Regarding the relationship between satisfaction with orthodontic treatment and quality of life, respondents who were more satisfied currently and who were neither quite confident nor quite unconfident were ahead of their counterparts in quality of life. Concerning the reason for receiving orthodontic treatment, quality of life was lower among patients who started to receive treatment due to pronunciation problems (p=0.013), chewing difficulty (p<0.001), and temporomandibular joint click sound (p<0.001). With regard to influential factors on oral health-related quality of life, time for starting to receive orthodontic treatment was most influential (p<0.001), followed by current satisfaction (p<0.001), changes in confidence (p=0.003), self-rated teeth status (p=0.008), and type of occlusion (p=0.019). Therefore, accurate analysis of the oral health status of orthodontic patients and customized oral health education are required to improve quality of life even during the period of orthodontic treatment.

Purpose : Febrile seizures occur in childhood associated with a febrile illness not caused by infections of the central nervous system. Provoked seizures are identified with seizures in association with infections that do not usually affect the brain such as gastroenteritis, except criteria for other febrile seizures in this study. We studied seizures provoked by minor extracranial infections, to contrast them with febrile and provoked seizures. Methods : We retrospectively studied one hundred and twenty children with provoked and febrile seizures who visited Chungbuk National University hospital from January, 2000 to December, 2004. Among these children, 36 patients were determined as provoked seizures and 84 patients as febrile seizures. We compared the distribution of minor infections between the patients with provoked seizures and those with febrile seizures, and studied risk factors of subsequent unprovoked seizures after febrile and provoked seizures associated with minor infections. Results : We analyzed the records of 120 children aged from 1 month to 15 years. The common etiologies of minor infections were gastroenteritis and respiratory infections. In the group of febrile seizures, there was a significantly greater proportion of patients with respiratory infections (58.3%) and a lesser proportion of those with gastroenteritis (25.0%). But there was a higher incidence of gastroenteritis (50.0%) in the provoked group. Comparing the distribution of etiologies between the patients with provoked seizures and those with febrile seizures seemed a significant difference. But, there were no difference between the provoked seizures and febrile seizures in the risk for subsequent unprovoked seizures. Conclusion : In conclusion, the leading cause except brain involvement is gastroenteritis in patients with provoked seizures, and respiratory infection in those with febrile seizures. Thus we need prompt recognition of, and medical attention given to, seizures associated with minor infections.

With the continuous expansion of highway network and its traffics, neighboring wildlife habitats are splitted into smaller and more isolated patches. The infrastructures contribute to the wildlife-vehicle collision by creating barriers to animal movement. This kinds of traffic accidents are dangerous factors to the drivers' safety and the facilities on the highway as well as to the wildlife themselves. One of the most common ways to prevent habitat fragmentation are fauna crossings and fences. The cost of the mitigation measures to prevent wildlife-vehicle collision could be monetized. However their economic benefits are difficult to be measured. Using contingent valuation method, this study tries to estimate the economic valuation of wildlife collision prevention projects on the Korean highways. The result shows that 43.88% of Korean household had the positive willingness pay to the projects. Moreover, we found that the recognition of the project or the favourable attitude to the environmental issues could raise the willingness-to-pay. Therefore, active public relation on the project could make the friendly public opinion and increase the number of the household which has the positive willingness-to-pay on the project.
