The purpose of the study was to explore whether the Cyber Motion sickness used VR causes a change in the dynamic balance and fall. For 39 people who voluntarily participated in this study, this study measured the motion sickness questionnaires, the heart rate and stability of limit test in BioRescue. The study used Samsung Gear VR and applied the games to the To the homeland. The game proceeded 20minutes. Although the value of the stability after a VR application is slightly reduced, it did not reach statistical significance. The motion sickness questionnaires increased, and it had a statistical significant impact. Also Heart rate increased and it had a statistically significant impact. A virtual reality game affect for getting motion sickness but it did not affect the dynamic balance. So, cyber motion sickness caused by virtual reality wear does not result in decreased balance and falls.

Cancer patients have been suffered from the instability of mind/body and unbalanced homeostasis because of cancer progression and medical treatment such as chemotherapy, It is very important that appropriated actions can be promptly taken by monitoring cancer patients' mental conditions. For this reason, it is crucial to develop a monitoring method which is convenient and not harmful to their body. Brain-computer-interface(BCI) system is introduced for the purpose in this paper. Prefrontal brain waves of cancer patients and control groups have been measured by a portable neurofeedback(NF) system based on self-regulation of the human electroencephalogram(EEG). The NF system consists of the portable EEG amplifier and a headband with dry electrodes placed on Fp1 and Fp2 sites. Patterns of the prefrontal brain waves taken by computer are correlated to brain quotients by EEG-analysis program. Basic rhythm quotient, attention quotient, emotional quotient, anti-stress quotient and correlation quotient of control group have shown high significant level compared with the cancer patients group. On the other hand, the EEG patterns analysis is shown its possibility to be an important methodology of monitoring cancer patients' condition.

This study aimed for in-depth observation of the status quo of the youth generation's happiness utilizing the Better Life Index and the World Value Survey. To serve this purpose, the study selected 11 of the Organization for Economic Cooperation and Development(OECD) member countries (Australia, Estonia, Germany, Japan, Korea, Mexico, New Zealand, Poland, Sweden, Turkey, United States) that overlapped with the subject countries of the World Value Survey. The results of the observation first revealed that among the work-life balance levels of youth generations from across the 11 studied countries, the level for Korean youth was in a very poor state. Second, the happiness level of Korean youth also sat among the bottom ranks, with the aspects of politics, friendship, and career casting a heavy influence on importance to life; specifically, the youth generations of Turkey and Germany showed high levels of life purpose, while Korean youth displayed outstanding results in the challenge aspect. The third finding of this study reported that family, religion, power, benevolence, and challenge were commonly related to the happiness level of youth generations in countries with a higher work-life balance. The results of this study are expected to contribute to the much needed attention and support for improving the happiness level of the Korean youth generation, who will eventually play the leading role in our future society.

Developing middle and high students' information literacy and creative problem-solving skills in this information-oriented society is very important and for this reason, the subject of informatics has been established. However, little research on creative problem solving literacy of informatics textbooks has been conducted. Therefore, the purpose of this paper is to quantitatively analyze whether 'problem-solving methods and procedures' parts in informatics textbooks in middle schools present creative problem solving literacy or not and in what degree. Data were quantitatively analyzed using the Gil-Su Choi method. The result of data analysis indicated that all the textbooks turned out to be correct range in the category of the "composition of various learning activities," but got out of range in some categories such as "problem-solving process reflection" and "problem-solving strategy proposal". Also a few textbooks haven't satisfied in important indexes and activities. So, we suggest that more 'problem-solving process reflection' and 'problem-solving strategy proposal' parts should be included in the informatics textbook and more various forms of learning activities be utilized well as the ratio of activities needed primary and high mental processes be kept the balance.

The purpose of this study was to analyze the regional distribution of the number of social welfare facilities per 100,000 population by using the concentration index(CI) and to evaluate the relationship with the local welfare environment. The results of the analysis are as follows. First, the distribution of social welfare facilities between urban and rural area were distributed in rural areas. And concentration of rural area was gradually decreasing. Second, the concentration index of the social welfare institution was calculated as the negative index. Therefore, social welfare facilities are concentrated in rural areas. However, the absolute value of concentration index decreased. Finally, there are many social welfare facilities in areas with poor economic conditions, low incomes, low welfare budget input, and poor social demolition indicators. In the future, the relationship between inequality of regional distribution of welfare resources and the relationship between local welfare environment should be continuously monitored.

Purpose: We examined the effects of the 8-week moderate-intensity Pilates exercise program on body composition, balance ability, metabolic parameters, arterial condition, and eating habits among overweight and obese women. Methods: From the general sample of overweight or obese Korean women (body mass index ≥ 23 kg/m² ), those who had not been diagnosed with any chronic degenerative diseases were enrolled in the study (n = 39). After 8 weeks of the Pilates exercise program, the participants were subdivided into adherence and non-adherence groups. Among the study participants, 24 women were matched for age and menopausal status to reduce the bias, and then finally included for the comparison (Pilates-adherence, n = 12; Pilates-non-adherence, n = 12). Results: The body balance measured by the Y-balance test, body mass index, and subcutaneous fat areas were significantly improved in both groups. However, the Pilate-sadherence group showed more positive changes in body balance and had significant improvement in body composition parameters such as waist size, visceral fat area, systolic blood pressure, arterial aging index, fasting blood glucose, and glycated hemoglobin than the Pilates-non-adherence group. In addition, the nutrition quotient for Korean adults (balance, moderation, and behavior except diversity) were significantly improved in both groups after dietary education. However, the participants did not show dramatic improvement in the metabolic parameters, because all the study subjects were in relatively good health and did not have any diagnosed diseases. Conclusion: This study demonstrated that higher adherence to the Pilates exercise program together with a modification of eating habits may effectively improve body balance, body composition, and obesity-related parameters among overweight and obese women.
