According to Mental accounting theory, humans sort money according to their psychological purpose. It plays a major role as a means of self-control. However, humans sometimes make mistakes that violate very simple economic principles. Many consumers experience this mistakes. So consumers use account book to manage their income and expenses. These days, they use mobile account book applications. And because of platform characteristics, there are various user interfaces. This paper examines an efficient user interface design that can reduce errors caused by mental accounting and support rational economic activities. For this, we compared and analyzed households exposed on top of Application store based on advanced research on Mental Accounting. Through this case study, We found some cases of efficient user interface for reasonable consumption. In further studies, We will design optimal account book's UI and do a usability test based on this.

Smart clothing products can experience a decrease in performance and reliability due to various mechanical, biological, and chemical stress factors that occur throughout their life cycle. These issues can hinder consumer acceptance of the products. This study aims to enhance the reliability of smart clothing and facilitate quality control by analyzing and identifying the current status of international standardization for smart clothing and electronic textiles (e-textiles). The focus of this analysis was on the durability test methods in the use environment. Furthermore, similar standards published by different standardization organizations for durability tests were compared in depth. The study showed that a total of 27 international standards have been developed or are currently under development. The current standardization efforts mainly aim to develop functionality and durability test methods for smart clothing and e-textile products. A detailed comparison was made between two international standards (IEC 63023-204-1:2023 and AATCC TM210:2019) specifically in relation to the washing durability test method and the electrical resistance measurement standards (BS EN 16812:2016 vs AATCC EP13-2021), before and after the environmental exposure tests. Based on this comparison, several suggestions have been made and discussed for the future revision of these international standards.

In order to develop the program of oral hygiene education for elementary school senior-students, a questionnaire survey of elementary fourth, fifth and sixth students who are under continual control program of oral hygiene. (1) For tooth brushing time, after dinner is more than before. 73.7% of respondents brushed the teeth twice or more a day. (2) 62.1% of respondents took the cariogenic food twice or more a day. (3) 90.1% of respondents had visited a dental clinic. (4) Concerning fear for dental treatment, only 14.4% had a feeling of fear. (5) Regarding the experience with a preventive treatment, 39.7% had an experience with pit and fissure sealing, and 24.2% had an experience with the application of fluorides. (6) 46.2% of respondents had a preference for the fluoride mouth rinsing program, and 38.4% wanted that program to keep going on. As to the reason to favor the fluoride mouth rinsing program, 38.2% preferred it because of prevention of dental caries, and 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do. (7) Comparing with the research result in 2000, we proved positively the educational effect of brushing frequency, positive understanding and preference to water school fluoridation program, and got the negative data of experience of visiting to oral clinic and preventive treatment.

Objective : We retrospectively evaluated the efficacy of Gamma Knife radiosurgery (GKS) for recurrent nasopharyngeal carcinoma (NPC) in patients who previously underwent radiotherapy, and analyzed the treatment outcomes over 14 years. Methods : Ten patients with recurrent NPC who had previously received radiotherapy underwent stereotactic radiosurgery using a Gamma Knife^® (Elekta Inc, Atlanta, GA, USA) between 2005 and 2018. The median target volume was 8.2 ㎤ (range, 1.7-17.8), and the median radiation dose to the target was 18 Gy (range, 12-30). The median follow-up period was 18 months (range, 6-76 months). Overall and local failure-free survival rates were determined using the Kaplan-Meier method. Results : The NPCs recurred at the primary cancer site in seven patients (70%), as distant brain metastasis in two (20%), and as an extension into brain in one (10%). The recurrent tumors in seven of the 10 patients (70%) were found on the routine follow-up imaging studies. Two patients presented with headache and one with facial pain. Local failure after GKS occurred in five patients (50%) : two of whom died eight and 6 months after GKS, respectively. No adverse radiation effects were noted after GKS. The 1- and 3-year overall survival rates after GKS were 90% and 77%, respectively. The local failure-free survival rates at 6 months, 1 year, and 3 years after GKS were 80%, 48%, and 32%, respectively. The median interval from GKS to local failure was 8 months (range, 6-12). Univariate analysis revealed that using co-registration with positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) was associated with a lower local failure rate of recurrent NPC (p=0.027). Conclusion : GKS is an acceptable salvage treatment option for patients with recurrent NPC who previously received radiation therapy. PET-CT and MRI co-registration for dose planning can help achieve local control of recurrent NPC.

Genetic Algorithms are optimization algorithm that mimics biological evolution to solve optimization problems. Genetic algorithms provide an alternative to traditional optimization techniques by using directed random searches to locate optimal solutions in complex fitness landscapes. Hybrid genetic algorithm that is combined with local search called learning can sustain the balance between exploration and exploitation. The genetic traits that each individual in the population learns through evolution are transferred back to the next generation, and when this learning is combined with genetic algorithm we can expect the improvement of the search speed. This paper proposes a genetic algorithm based Cellular Learning with accelerated learning capability for function optimization. Proposed Cellular Learning strategy is based on periodic and convergent behaviors in cellular automata, and on the theory of transmitting to offspring the knowledge and experience that organisms acquire in their lifetime. We compared the search efficiency of Cellular Learning strategy with those of Lamarckian and Baldwin Effect in hybrid genetic algorithm. We showed that the local improvement by cellular learning could enhance the global performance higher by evaluating their performance through the experiment of various test bed functions and also showed that proposed learning strategy could find out the better global optima than conventional method.

The study was carried out to understand the inhabiting status and biological features of nutria (Myocastor coypus) in the Jeju Island from May, 2013 to August, 2016. Five individuals were captured by traps and two individuals were collected in dead. Of the 7 individuals, those whose bio-information could not be known were excluded to perform autopsy of the rest of them. The results from morphological, cranial and anatomical analyses, it was found that the females achieved sexual maturation but had no breeding experience. An adult male showed similar sizes to those found in the Korean Peninsula. After collecting the 7 individuals in 2013, 1 nutria individual was filmed by the scouting camera in May, 2014 but not captured. The long-term investigation of the research area found no inhibiting individual. It is deemed the nutria was either died of natural death or migrated. In order to establish a proper nutria control, the environmental characteristics of Jeju Island should be considered where indigenous and introduced species coexist in a limited space. Our findings will provide helpful information for understanding biological features of nutria and planning protection program of natural ecosystems of Jeju Island.

Purpose : We evaluated the prevalence and clinical, microbiological features of extrapulmonary tuberculosis (EPT) in pediatric patients. Methods : We retrospectively reviewed medical records of pediatric patients diagnosed with EPT at The Catholic University of Korea, Incheon St. Mary's Hospital between 2000 and 2007. Results : Of 109 patients diagnosed with tuberculosis (TB), 12 patients (11%) were admitted with EPT. At 2006-2007, the proportion of patients with EPT among patients with TB was the highest (20%) comparing with last 6 years. The ratio of male to female patients was 1.4:1 and the mean age was 9.2 years (range, 3 months-15 years). The involved sites were pleura in 5 (41.6%), central nervous system in 3 (25%), miliary TB in 2 (16.7%), gastrointestinal tract in 1 (8.3%) and bone and joint in 1 (8.3%). The most common symptom at admission was fever (91.6%) and mean duration of fever was 15.8 days (range, 0-47 days) in spite of the proper treatment. Confirmed rate for acid fast bacillus stain, culture, and polymerase chain reaction were 33.3%, 41.6% and 41.6%. Of 5 culture proven cases, 4 (80%) were resistant to more than one antituberculosis drugs. Eleven patients recovered without complication and 1 patient died. Conclusion : Total incidence of TB decreased steadily according to the nationwide survey. However, our results suggest that the proportion of diagnosis with EPT among diagnosis with TB in children has increased. Microbiological diagnosis of EPT in children was more difficult than that of pulmonary TB. And drug resistance rate has increased.
