Recently, with various developments made to smart-phones and other digital devices in the IoT environment, modern people tend to pursue comfort in their own lifestyles. These environment has helped us to obtain any information or data in despite of location and time. But it has caused them to be overly reliant on digital devices in doing any kind of daily work, trusting the digital devices more than oneself. As a result of this over reliance, modern people's memorizing and calculating ability have deteriorated critically. This symptom is known as the Digital Dementia. In this paper, we study the phenomenon of digital dementia caused by smart-phones, and we suggest a method of developing "memorize the phone number" game applications in IoT environment to the problem of digital dementia. Test results show that, through the use of application, not only the users were able to have fun memorizing the numbers, but also, to show improvement in their memorizing ability. Thus, we expect that the application suggested above will help in preventing digital dementia and maintain brain health.

User requirements for access and authentication increase daily because of the diversification of the Internet of Things (IoT) and social structures. The increase in authentication needs requires the generation of new passwords. Users want to utilize the same passwords for memorization convenience. However, system administrators request each user to use different passwords, as well as passwords that include special symbols. Differnet passwords and including special symbols passwords seem to exceed the tolerance range within your memorization skills. It fetches a very negative consequences in terms of password management. This paper proposes a preference symbol password system that does not require memorization by users. First, a survey is conducted to prove statistical safety, and based on this, an evolution-type password system that uses preference symbols is designed. Preference symbol passwords show superiority with respect to installation cost and convenience, compared with conventional non-memorizing password systems such as biometrics, keystrokes, and mouse patterns.

Many games for English vocabulary learning, such as hangman, cross puzzle, matching, etc, have been developed which are of board-type or computer game-type. Most of these computer games are adapting strategy-style game plays so that there is a limit on giving the fun, a nature of games, to learners who do not like games of this style. In this paper, a system for memorizing new English words is proposed which is based on a single-player car racing game targeting youths and adults. In the game, the core of our system, a learner drives a car and obtains game points by colliding with English word texts like game items appearing on the track. The learner keeps on viewing English words being exposed on the track while driving, resulting in memorizing those words according to a learning principle stating viewing is memorization. To our experiment, the effect of memorizing English words by our car racing game is good, and the degree of satisfaction with our system as a English vocabulary learning tool is reasonably high. Also, previous word games are suitable for the memory enforcement of English words but our game can be used for the memorization of new words.

Foreign language learners want to remember newly learned vocabularies for as long as possible. As demand for learning English as a second language grows, effective ways of memorizing English vocabularies also attract much interest so that various methods and apparatus are developed in order to support effective memorization. In this research, we introduce a new way of memorizing English vocabularies and evaluate the performance compared to an existing qualified method. Our study result shows that learners who memorize English words using our suggested method maintained a higher retention rate than those who studied using the existing method. From this research, we expect to gain new insights of effective way in learning English vocabularies.

This paper is aimed at finding whether foreign students' Korean speaking skills can be increased or not through memorizing whole Korean sentences and pair works. First, the advance studies on the effects of this teaching method were surveyed. Second, the activity of this study was mainly pair works with foreign students, so how to do this activity was described. This activity was intended to help each other with keeping study and correcting errors while drilling in class. Thanks to this convergence teaching approach the students' frequency of target language, the Korean language was dramatically increased, and their motivation and energy were brought from this activity. They have to do communications with each other because each pair was made of one Chinese and one Vietnamese. They have no choice but to use Korean in communication. Finally, the questionnaire and interviews also showed that almost all of the students were satisfied with this convergence teaching approach.

Many studies adopting brain functions to the engineering systems have been made for recent years as the brain Science has developed. If we investigate the parts which take part in memorizing and emotional process, we can know that Hippocampus of memorizing center and Amygdala of Emotional center closely cooperate each other. Actually Knowledge effects on Emotion and Emotion effects on Knowledge. During the human decision making, emotional factor has much important effects on Decision making process. For implementing more delicate intelligent system, the knowledge base coupled to emotional factor should be designed. Accordingly in this paper starting from the idea of cooperating system between Hippocampus and Amygdala,, we design Knowledge Emotion Binding System and propose Emotional changing mechanism by Memory retrieval and knowledge reasoning process.

As becoming an aging society, there is a rising interest on dementia. But Dementia prevention program, executed at the national level, is in insufficient state. In this study, to design and diffuse Dementia prevention program, this study conduct Cognition improvement program and evaluate cognitive function in aspects of Discrimination, Organization, Thinking, Memorizing, and Concentration capacity. So that this study try to investigate how this Cognition improvement program will affect in detail to cognitive function in senior people. This study designed Silver Cognition program for 5 aspects of cognitive function; Discrimination, Organization, Thinking, and Concentration capacity. And this studyrecruited experimental group with control group, and conducted the program to them for 3 months. At the start and the end of the program, this study evaluated their MMSE-DS score, Geriatric depression scale, Quality of life score, and cognitive function test score by survey. Finally, this study compared and analyzed these first and second score to find the effects of this program to cognitive function. As the results compared between first and second score of MMSE-DS test, Geriatric depression scale, Quality of life scale, and cognitive function test, Silver Cognition program has a significant effects to improve cognitive function, MMSE-DS score and Geriatric depression scale. As the results of the test on cognitive function in 5 aspects, cognitive function is more improved in the order of Memorizing, Thinking, Concentration, Discrimination, and Organization capacity. After the Silver Cognition program, Memorizing and Thinking capacity have most improvement. But aging of brain function is faster in these two capacity, so if more concentrated education is conducted for these two capacity, then it will bring better effects for prevention of dementia.

Since scientific management techniques are introduced into Korea about 1958, the backwardness of Korea companies and the ignorant owners of the companies had been main obstacles in aboriginality of those techniques. With the activation of industry in 1970s, however, the adaptation of IE is also activated. This paper, although it may be slipshod, describes the present situation as well as the adaptation history of IE techniques. This is for the expected necessity of memorizing the introduction of IE in the future.
