Older people, because of the psychological and physiological changes related to the aging process are more vulnerable to experiencing powerlessness than any other age group. This self destructive cycle of depression in older people related to the experience of continued and long term powerlessness can lead even to death. The purpose of this study was to measure powerlessness and resources to increase power in older people, and to measure the effectiveness of a psychological rehabilitation program for reducing powerlessness. The research methodology used was a two step process. In the first step, a survey was done of perceived powerlessness and power resources comparing four groups of elderly people ; those living at home, those in hospital, those living in nursing homes and those attending educational programs for the elderly. The total sample size was 236. In the second step, a psychological rehabilitation program was carried out, pre and post measurements were taken related to this program. The sample consisted of 29 residents in a nursing home. The results of the study are as follows : 1. Powerlessness was classified as cognitive, emotional, activity and learning. The lowest score for powerlessness was in the area of activity, that is the people in the sample felt more power concerning their activities. The highest score was in the area of cognition where they felt they had less power. 2. When the different groups of elderly were compared, it was found that the residents of the nursing home had the highest score on perceived powerlessness and the group who were living at home had the lowest score. 3. Among the general characteristics, the factors influencing the powerlessness score were age, sex, level of education, financial resources and health status. In the interaction effects among these factors, it was found that level of education and health status were factors influencing perceived powerlessness. The elderly with lower education and poorer health status had the higher scores for perceived powerlessness. 4. The power resources could be classified into the following areas : physical strength, emotional strength, positive self-image, energy, knowledge, motivation and belief system. Belief system was given the highest score among the power resources and energy, knowledge and motivation were given low scores. 5. The group participating in an educational program for the elderly had the highest score for power resources while the group made up of residents of a nursing home had the lowest score as well as the highest score for perceived powerlessness. 6. The factors influencing the power resource scores were sex, level of education, financial resources and health status. In the analysis of the interaction effect among the factors, it was found that sex, level of education and financial resources were the factors that influenced the power resource score, that is, women, those with a low level of education and those with poor financial resources reported a lower level of power resources. 7. There was a negative correlation between perceived powerlessness and power resources in the elderly in this study. Since power resources explainded 49% of the variance for powerlessness, it can be concluded that the power resources can be used to reduce powerlessness. 8. The psychological rehabilitation program was carried out with the nursing home residents over a period of five weeks. No statistically significant difference was found in the scores on powerlessness between the pre and post tests, but there was a slight decrease in the raw scores on the post test for emotional, activity and learning powerlessness. There was a statistically significant increase in the power resource scores for emotional strength, positive self-image, energy, knowledge and motivation in the post test as compared to the pre test. In conclusion, the study indicates that a psychological rehabilitation program for the elderly could be effective in increasing power resources and this in turn could lead to a decrease in perceived powerlessness.

Motivation: Protein-protein interaction plays a critical role in the biological processes. The identification of interacting proteins by bioinformatical methods can provide new lead In the functional studies of uncharacterized proteins without performing extensive experiments. Results: Protein-protein interactions are predicted by a computational algorithm based on the weighted scoring system for domain interactions between interacting protein pairs. Here we propose potential interaction domain (PID) pairs can be extracted from a data set of experimentally identified interacting protein pairs. where one protein contains a domain and its interacting protein contains the other. Every combinations of PID are summarized in a matrix table termed the PID matrix, and this matrix has proposed to be used for prediction of interactions. The database of interacting proteins (DIP) has used as a source of interacting protein pairs and InterPro, an integrated database of protein families, domains and functional sites, has used for defining domains in interacting pairs. A statistical scoring system. named "PID matrix score" has designed and applied as a measure of interaction probability between domains. Cross-validation has been performed with subsets of DIP data to evaluate the prediction accuracy of PID matrix. The prediction system gives about 50% of sensitivity and 98% of specificity, Based on the PID matrix, we develop a system providing several interaction information-finding services in the Internet. The system, named PreDIN (Prediction-oriented Database of Interaction Network) provides interacting domain finding services and interacting protein finding services. It is demonstrated that mapping of the genome-wide interaction network can be achieved by using the PreDIN system. This system can be also used as a new tool for functional prediction of unknown proteins.

Many construction projects involve a plethora of safety-related problems that can cause loss of productivity, diminished revenue, time overruns, and legal challenges. Incorporating data collection and analytics methods can help overcome the root causes of many such problems. However, in a dynamic construction workplace collecting data from a large number of resources is not a trivial task and can be costly, while many contractors lack the motivation to incorporate technology in their activities. In this research, an Android-based mobile application, Preemptive Construction Site Safety (PCS2) is developed and tested for real-time location tracking, trajectory prediction, and prevention of potential collisions between workers and site hazards. PCS2 uses ubiquitous mobile technology (smartphones) for positional data collection, and a robust trajectory prediction technique that couples hidden Markov model (HMM) with risk-taking behavior modeling. The effectiveness of PCS2 is evaluated in field experiments where impending collisions are predicted and safety alerts are generated with enough lead time for the user. With further improvement in interface design and underlying mathematical models, PCS2 will have practical benefits in large scale multi-agent construction worksites by significantly reducing the likelihood of proximity-related accidents between workers and equipment.

최근 인터넷상에서는 원격교육이나 온라인 교육에서 다양한 교육용 디지털 컨텐츠가 제공되고 있다. 특히 에듀테인먼트분야가 활성화되면서 흥미위주의 교육 컨텐츠가 많이 개발되고 있다. 하지만 컨텐츠가 적정기간($1{\sim}2$년) 동안 학습자가 흥미를 잃지 않고 스스로 학습하도록 유도하는가 라는 질적인 면에서 고려해 볼 때 부족한 면이 많다. 그러므로 학습자로부터 자발적이면서 적극적인 학습을 촉진시키기 위해서 학습자의 학습동기를 강화시키는 시스템이 필요하다. 본 논문은 후견인과 학습자가 제시한 목표의 성취도에 따라 보상을 제공하는 학습보상시스템 (LRS)을 설계 및 구현한다. LRS는 기존의 에듀테인먼트 컨텐츠를 활용하여 동시에 흥미와 보상을 함께 제공함으로써 교육효과증진을 목적으로 한다.

The purpose of this study was to examine the state of smoking among some college students, the smoking motivation of smoker students, what made them quit smoking and how they got ready for giving up smoking, as smoking had a huge impact on national health and there was a desperate necessity for preventive antismoking education programs to let students keep away from smoking. After a survey was conducted with self-administered questionnaires from October 1 through November 1, 2006, the responses from 400 students were gathered, and 384 answer sheets were analyzed except 16 incomplete ones. The findings of the study were as follows: 1. By gender, 62.4% of the male students and 28.6% of the female students were smokers, and the state of smoking was statistically significantly different according to their gender(p<0.05). 2. The largest number of the male students, which accounted 44.1%, started smoking in their high school days, and 39.5% of the females did that in middle school. As for a daily mean amount of smoking, 41.8% of the male students, the greatest percentage, smoked 10 to 19 cigarettes a day, and one to nine cigarettes were most common among the females, which represented 57.9 %. But the gap between the two was insignificant(p>0.05). As many as 83.6% of the males and 86.8% of the females had ever attempted to quit it. 3. Concerning awareness of antismoking policies, they felt that a raise in cigarette price would lead to less smoking, and that antismoking advertisement or posters through television or newspaper would deliver the same results as well. There was a statistically significant difference among their awareness(p<0.05). 4. Regarding preparation stage for quitting smoking, 31.3% of the male smokers had no intention to give it up, and 23.2% considered it. 36.7%, the largest percentage, got ready to refrain from it. Among the female smokers, 34.2% had no plans to abstain from smoking, and 36.8% took it into consideration. 23.7% got ready to do that. The females who got ready for that were outnumbered the males who did. 5. As to connections between the state of smoking and relevant knowledge, the students didn't have a good knowledge on that, and a statistically significant difference existed between the smokers and nonsmokers in smoking knowledge. 6. As for knowledge about oral diseases, they were highly cognizant of the relationship of smoking to tooth discoloration, nicotine stomatitis and bad breath, but they didn't know well about its relationship to delayed recovery from dental treatment, implant failure and ozena. Their smoking condition made a statistically significant difference to their knowledge(p<0.05). In the future, sustained research efforts should be channeled into determining how much smoking affects health and concerns oral diseases, and antismoking counseling programs should be prepared to bolster people's awareness of oral health.

Purpose - The purpose of this study is to investigate the relationship among narcissism, usage motives, usage behaviors, satisfaction with and continuance intention to use fashion social media. Research design, data, methodology - A questionnaire survey was used to collect data after conducting a pilot test. Based on the reliability test of the preliminary questionnaire used for the pilot test, the questionnaire was revised. The final questionnaires were administered to 238 fashion social media users and 216 were used for the data analysis. To assess the validity of these measures, exploratory factor analysis and the confirmatory factor analysis were performed. Structural equation modeling analysis were employed for data analysis. Results - Five factors of the usage motivation of fashion social media were extracted: information-seeking, relationship-seeking, practicality-seeking, enjoyment-seeking and self-expression motives. The statistical analysis confirmed the influence of the narcissism tendency on all of the usage motives of fashion social media, three of the fashion social media usage motives influencing information diffusion behavior, and the influence of the information diffusion behavior on users' satisfaction and continuance intention to use fashion social media. Narcissism exerted the highest influences on self-expression motive followed by information-seeking, enjoyment-seeking, relationship-seeking and practicality-seeking motives in order. Factors affecting fashion information diffusion behaviors are practicality-seeking motive, self-expression motive, and relationship-seeking motive. The greater the diffusion of information, the higher the satisfaction with using fashion social media. The consumers with higher satisfaction intended to use fashion social media and share information more frequently. Conclusions - The results indicate that narcissism is an important factor in fashion social media usage motivation. The main motives for narcissistic people to spread information is for the practical purpose at the most, and then to express their personality and style, and to build relationship with others. The satisfaction through active information sharing behaviors seems to play a key role to lead high continuance intention of fashion social media. These implies that marketing strategies to satisfy consumers' narcissism and motives to use social media, and to stimulate the information diffusion behaviors can be used to meet their needs for higher satisfaction with fashion social media.
