The aim of this study is to investigate the influence of graphic calculator in the teaming of function of the underachieved students in the second grade of middle school. Under this purpose of the study, we devised the instruction-plan which incorporates the using of graphic calculator into the traditional paper-and-pencil teaming environments, and executed the function-instruction with the underachieved students according to the devised instruction-plan. During the lesson hours, we observed and analysed the contributions and the carefulness of using graphic calculator in the learning of function of the underachieved students. Furthermore, we carried out the pre-test and the post-test to examine the effects of using graphic calculator in the learning of function of the underachieved students.
Purpose: This study aimed to investigate the factors that increase fall risk in the residential environment and the perceived fall risk among community-dwelling elderly through comparisons between fallers and non-fallers. Methods: The subjects were 95 community-dwelling elderly aged 65 years and over residing in the metropolitan city of Ulsan. A structured questionnaire consisting of items on sociodemographics and health- and fall-related characteristics was used and data were collected from July to August 2015. The data were analyzed with the SPSS/WIN program. Results: Among recent fallers, 38.9% had diagnosed diseases when the fall occurred, 56.87% were fearful of a recurrent fall, and 86.5% stated that they were increasing their carefulness but that had led to a decrease in activity. There were significant differences between elders who had fallen at least once and elders who had no falls in age, health status, depression, the experience of falling, fear of falling, diseases, and medications. Conclusion: The results indicate a need to assess risk factors to identify older adults with a high risk for falling and the need to develop multifactorial intervention programs that consider both environmental and perceived risk factors as well as physical risk factors to reduce and prevent falls among the elderly.
The interior designs and architectures are definitely important to the disabled because it could improve their independence considerably. Although the design is meaningless if for each disabled's symptom is not considering, the research on design to support detail symptom of each disabled is insufficient. This paper studies the bathroom in house for the disabled of hemiplegia after a stroke. The bathrooms is important space that cause many unnecessary activities and accidents without carefulness. Study method makes framework through principle of universal design and feature of hemiplegia after a stroke. We visit three places where the disabled live in and used qualitative analysis. After checking the present condition of the bathroom, a request and necessity of the disabled through observation and semi-structured interview. According to the result of this study, the obstruction factors were increased when the disabled try to use both hands or to reach and pick up objects, to move and to assist the severe disabled in the bathroom. Finally this study suggests design guidelines based on principle of universal design and factors for better bathroom design for the disabled.
After observing the alkali-silica reaction of the mortar that contains glass abrasive sludge, when evaluating it by a mineral or chemical point of view, it contained reactive silica $(59{\sim}67%)$ and $R_20$ elements $(4.3{\sim}9.8%)$. Also, when evaluated by the mortar bar method, an addition of 5 wt% of CRT glass abrasive sludge is judged harmless. However when adding more, there appear severe contractions, thus carefulness is needed while using. Less than 0.10% of expansion was measured when adding up to 30wt% of flat glass abrasive sludge. However, after 30 days of the measurement, more than 0.1% rate of expansion was measured when adding more than 5 wt%. Therefore, more detailed experiments are needed in case of more than 5 wt%.
Recently, the interesting of customers in online auto insurance is rapidly increasing. The one of major reasons is economical benefit. offline auto insurance products as a service formed high price. However, online auto insurance relatively formed low price. Thanks to these characteristics of online auto insurance has gained great popularity. Therefore, in purchasing online auto insurance, consumers carefully buy products of auto insurance. In this study, we classified the $2{\times}2$ matrix (online preference group, economic pursuit group, convenience oriented group, and carefulness approach group) in online auto insurance consumers focusing on the perceived benefits and price acceptance. From an economic point of view of consumers around the perceived benefits and price acceptance, we analyzed the relationships among easy of use, usefulness, attitude, and purchase intention in automobile e-shopping mall. The results of this study will provide the useful implications for the planing CRM(customer relationship management) strategy for improving purchase intention of customers to online insurance companies.
Objective: This study was performed to identify the related factors of exercise injury throughout the actual cases among patients. Method: The subjects of the study consisted of 304 patients(209 male and 95 female) over 20's in seoul and kyonggi area, and data collected by using questionnaires were analyzed with SPSS/WIN 11.0 program. To prove the relative factors of exercise injury from hospital patients Results: 1) It was found that the general degree of exercise injury showed significant difference regarding gender, age and education level. In other words, if it was male, young and high school graduate, the portion of exercise injury for the person was higher than others. On the other hand, the duration of medical treatment for the patient, who is male, old and college graduate took longer than the others. 2) It demonstrated that the lower extremity was most intensively damaged due to the exercise injury, especially, knees and ankles had the most portion of exercise injury and a sprain was the most common form of exercise injury for these body parts. 3) The degree of exercise injury regarding of exercise maintains significant difference with the frequency of exercise. In fact, the more exercise was done by a person such as 3 to 4 days a week, the less duration of medical treatment for the person was taken. 4) It also showed that there was significant difference between the habit of exercise and the degree of exercise injury. In other words, a person had better exercise habit, it took the person less duration of medical treatment. As well, if someone had better warming up, he or she had lower degree of exercise injury after all. Conclusion: Consequently, according to the data, the research suggested that the male needed more carefulness than the female in exercise. Old age people needed to be more careful of getting sprain of knee and ankle in particular. As well, it concluded that people needed not only enough warming up before doing exercise but also positive habit of exercise in order to minimize the exercise injury.

Although Hi-pass have been operated for alleviating traffic congestion and enhancing mobility in expressways since 2000, there is not any standard for safe operation. For that reason, we investigated about tubular markers, which is a typical facility for safety in Hi-pass. Tubular Markers are installed for separating same or opposite traffic flows spatially, supporting the marks at a place which has not only high possibility of accidents but distinguished carefulness of drivers. In this paper, it is noted two considerings; one is prevention of accident from the speed gap of autos and Hi-pass vehicles; the other is guarantee of necessary distance that Hi-pass vehicles could be changes the lanes for off-ramp. Focusing those considerations, it is proposed not only prefer distance of tubular markers, but also fundamental basic subjects. We anticipate that the results of this study would be useful reference in more safe and efficient tollgate operation of Hi-pass.
As mentioned above, Korean restaurant's menu price is to be decided by combining various factors. Korean restaurant is demanded to decide menu price more carefully than other restaurants do, because the number of Korean restaurant is the largest in Korea and Korean food is the most popular among the Korean people. Korean restaurant cannot neglect price competitiveness and is often given complaints from its customers. Because of such management difficulties, the number of Korean restaurant has recently decreased at special class hotels as well as common hotels. Korean restaurant managers are demanded to make efforts to inherit Korean tradition and culture by keeping pride and responsibility. Until now, Korean restaurants are thought to decide the menu prices in short-sighted, non-scientific and haphazard way of thinking. Such price decision factors have established traditions and have been generally accepted to let Korean restaurant managers lose carefulness at the menu price decision. In advanced countries, however, they recognized the importance of the price decision since the 1960's or earlier to research the menu price systematically and scientifically. Before deciding the menu prices, Korean restaurant managers are demanded to investigate various kinds of factors carefully and spend a lot of time to calculate direct costs, that is, one of the most important factors of cost calculations. The managers are demanded to decide the menu prices in reasonable and future-oriented way by keeping not private thinking but correct information and judgment. The sale of each menu has difference, while the menu price increase has been evaluated to be successful from overall point of view. Despite of increased total sale, there was not much difference of net profit because of increased material costs. However, higher level of the customers produced comfortable and cozy atmosphere of the restaurant enough to satisfy customers, and improved service quality much more. Not only customer satisfaction but also improved service quality is thought to play an important role in invitation of future customers.
The 3D game graphic technology has become an important factor in the contents field with the game contents development. In particular, game character technology provides a realistic technique and visual pleasure, as well as an intermediate step in the immersion of the game in which the game might create an optical illusion that enables the player to enjoy heroic adventure in the game. The high expression level of characters in 3D games is a key factor in the development process, with details and carefulness of the character setting work [3]. In this paper, we propose a character representative technique applied to mobile games using mathematical model of radiosity energy, spectral radiance model, and ray tracing model method using 3D unity game engine with sensible AI algorithm for game implementation. As a practical application to the game contents, it was found that the projection of the surface in the rendering process and the game simulation might change according to the lighting condition of the game content environment, so that the high quality of game characters was simulated.
The purpose of this study was to determine how often toddlers and preschoolers in kindergartens have accidents and what factors affect the accident rate. The study population consisted of 150 children who were attending at nursery schools and 150 children who were attending at kindergartens. The data was collected from ten nursery schools and five kindergartens from five districts in Daegu. The questionnaires were distributed to teachers of participating nursery schools and kindergartens to be completed using nursing care records in the institutions and by interviewing children's parents about all of the accidents happened in a previous year. Data were collected during the period of August 1 through 31, 2002. The results of the study are as follow: 1. Among 300 children, 282 had 506 accidental injuries during the study period. 2. The month, the day and the time with the highest accident rate were April. Monday, and between 2 and 4 o'clock in the afternoon, respectively. 3. Locations where the injury took place most included nursery schools or kindergartens, around the homes of the children, and inside the home. 4. Most accidents were occurred due to lack of carefulness of the children, and the most prevalent forms of injury was abrasions. 5. Most frequently injured part of the body was legs of the children. 6. Most injuries were healed within three days and required first aid measures to disinfect the wound. Mostly, these were performed by family members at home. Some children go to the hospital to suture the open wound. Most frequent type of complication was scar formation and the cost of the treatment ranged from 9,000 to 30,000 won. 7. Children's age. sex, birth order. personality. type of family composition. type of residency. father's occupation, father's age, and mother's age were significantly related to the frequency of injury among children. Children who were in nursery schools and kindergartens need their assessment for accident involving condition according to seasons, time. place. This study provided a very useful and important data to prepare accident prevention education program and accident prevention strategies, and to develop Injury Surveillance System.
