Recent advances in healthcare technologies along with improved medical care have led to a steady increase in life expectancy over the past few decades. As a result, the world population is aging rapidly. Various researches have been carried out to provide information and communication technologies based solutions that enhance the well-being of elderly people and provide them with a well margin of independency in their daily life. Ambient assisted living can be defined as the use of information and communication technologies in a person's daily living and working environment to enable them to stay active longer, remain socially connected and live independently into old age. Since the information transmitted in ambient assisted living systems is very sensitive, the security and privacy of such data are becoming important issues that must be dealt with. In this paper, we propose a novel lightweight authentication protocol for the ambient assisted living systems. The proposed authentication protocol not only supports several important security requirements needed by the ambient assisted living systems, but can also withstand various types of attacks. In addition, the security analysis results show that the proposed authentication protocol is more efficient and secure than the existing authentication protocols.

The purpose of this study were to identify the dietary practices of vulnerable older adults and to assess the foodservice and food provision service programs perceived by the health and welfare service providers in the community. A survey was conducted on health and welfare service providers working in outreach community centers and community health centers in Seoul. A total of 260 nurses and social workers participated in the survey and 224 responses were used for data analysis after excluding significant missing data. The respondents consisted of nurses (58.5%) and social workers (41.5%). In terms of the dietary life of the vulnerable older adults, they perceived that the food cost was burdensome to the older adults and poor dental conditions prohibited them from eating various foods. The health and welfare service providers rated highly for 'home-delivered meal and side dish services are effective for checking older adults' conditions' but rated low for availability of menu choices. In targeting vulnerable older adults for food and nutrition service programs, the home-delivered meal service was found to be suitable for older adults living alone, those over age of 80 years, those with mobility difficulties, and those with economic difficulties. The food provision service was appropriate for older adults living with their spouse or other family members. Vulnerable older adults are a heterogeneous population with diverse needs related to food and nutrition. Home-delivered meal/side dish service and food provision services will achieve their goals when they reach the correct targets with a customized service.

Malaria remains one of the leading health burdens in the developing world, especially in several sub-Saharan Africa countries; and Uganda has some of the highest recorded measures of malaria transmission intensity in the world. It is evident that the prevalence of malaria infection, the incidence of disease, and mortality from severe malaria remain very high in Uganda. Although the recent stable political and economic situation in the last few decades in Uganda supported for a fairly good appreciation of malaria control, the declines in infection, morbidity, and mortality are not sufficient to interrupt transmission and this country is among the top 4 countries with cases of malaria, especially among children under 5 years of age. In fact, Uganda, which is endemic in over 95% of the country, is a representative of challenges facing malaria control in Africa. In this study, we evaluated an active case detection program in 6 randomly selected villages, Uganda. This program covered a potential target population of 5,017 individuals. Our team screened 12,257 samples of malaria by active case detection, every 4 months, from February 2015 to January 2017 in the 6 villages (a total of 6 times). This study assessed the perceptions and practices on malaria control in Kiyuni Parish of Kyankwanzi district, Uganda. Our study presents that the incidence of malaria is sustained high despite efforts to scale-up and improve the use of LLINs and access to ACDs, based on the average incidence confirmed by RDTs.

Korea is currently an aging society with a population of about 15 percent over the age of 65. Accordingly, the government is currently working on a number of measures. However, the problem that is rapidly increasing rather than decreasing is the traffic accident of the elderly. It has increased so much that we can check it out in multiple media right away. An average of 110 elderly people die or are injured in traffic accidents a day, or about 40,000 a year. The National Police Agency reported a 25 percent increase in elderly traffic accidents from five years ago. This paper analyzes traffic accidents of senior citizens through the Big Data analysis and R programming language to present the main causes of traffic accidents of senior citizens and areas where measures are needed to prevent them.

The purpose of this study is to promote the efficiency of the management of the controls organization in the university hospitals and general hospitals by evaluating the factors underlying organizational conflict. The subject population included 351 hospital workers randomly selected from two general hospitals of less than 200 beds and two university hospitals over 500 beds in Seoul area. Data were collected through a survey questionnaire. To define related factors for the level of conflict among departments in each hospitals multivariate regression analysis was conducted. Independent factors were characteristics of subjects, conflicting factors between the departments. The results are as follows: 1. Those in high job position group demonstrated significantly higher level of conflict between departments. Those working in the general hospitals, who were older and had long-term tenure at current working hospital had higher level of conflict between the departments. 2. Concerning the involvement of conflicting factors and the level of conflict in the employees' there was statistically significant positive correlation between reliability and job-related and intradepartmental level of conflict in university hospitals. There was a significant positive correlation between interdepartmental conflicting factors of mutual dependence, difference in goal/orientation and interdepartmental level of conflict. 3. In the university hospitals, among the interdepartmental factors, mutual dependence and difference in goal/orientation had statistically significant influence and showed a positive relationship with interdepartmental level of conflict. In the general hospitals, job position was a significant factor which showed that those in high position such as section chief or above, compared to those in general position had higher level of conflict. Among the interdepartmental characteristics, factors of mutual dependence and goal/orientation had statistically significant influence and showed a positive relationship with interdepartmental level of conflict. In the general hospitals setting efforts to reduce conflict in areas among workers with high position, old age, and long tenure and those in medical care department should be made and prudent management and planning for improved manpower and increased budget or efficient allocation and clear definition of job description are necessary to adequately assess. In the university hospitals setting efforts to reexaminitation of the organizational structure and efficiency conveyance of information and efforts to resolve conflict among young workers with lower level of education is need. This study has its own merit in comparing empirically the conflict among hospital workers in the university hospitals and general hospitals. Future study are needed with respect to the relationship between interdepartmental level of conflict and the effectiveness of the hospital organization for improved resolution of conflict in the organization and hospital management.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. Methods: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. Results: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). Conclusions: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

Objectives : Our objective was to examine and evaluate the psychological health of the residents of Taean during the cleanup of the Hebei Spirit(HS) oil spill and to review some factors associated with the results. Methods : A community survey of 71 men and women was conducted 8 weeks after the HS oil spill. Questionnaires used were the PWI(Psychological Well-being Index) scale for psychosocial distress, the CES-D(Center for Epidemiologic Studies-Depression) scale for depressive symptoms, and a questionnaire created to assess suicidal impulses. Results : The overall prevalence of high-risk psychosocial distress among the study group was 64.2%. The percentages of respondents with scores on the CES-D Scale above 16 and above 21 were 77.6% and 62.7%, respectively. The percentage of respondents categorized as having suicidal impulses was 18.3%. When compared with unexposed groups in the general population taken from various sources, the residents of Taean were 6.5 times as likely to have high stress and 9.4-9.7 times as likely to be depressed. No significant difference in the rate of suicidal impulse was found between the residents of Taean and the general population. Factors associated with high stress, depression, and suicidal impulses were age, a change in income, educational level, number of days working on the cleanup, and positive responses to questions about "affected daily activity" and "hospital visit due to work on cleanup". Conclusions : The results suggest that the HS oil spill had a significant impact on the psychological health of residents of Taean, but the comparability of the unexposed groups is a limitation of the study.

This study aims to solve the entangled loop between demographic transition (DT) and economic growth by analyzing cross-country data. We undertake a national-level group analysis to verify the compressed transition of demographic variables over time. Assuming that the LA (latecomer advantage) on DT over time exists, we verify that the DT of the latecomer is compressed by providing a formal proof of LA on DT over income. As a DT has the double-kinked functions of income, we check them in multiple aspects: early maturation, leftward threshold, and steeper descent under a contour map and econometric methods. We find that the developing countries (the latecomer) have speedy DT (CDT, compressed DT) as well as speedy income such that DT of the latecomers starts at lower levels of income, lasts for a shorter period, and finishes at the earlier stage of economic development compared to that of developed countries (the early mover). To check the balance of DT, we classify countries into four groups of DT---balanced, slow, unilateral, and rapid transition countries. We identify that the main causes of rapid transition are due to the strong family planning programs of the government. Finally, we check the effect of latecomer's CDT on economic growth inversely: we undertake the simulation of the CDT effect on economic growth and the aging process for the latecomer. A worrying result is that the CDT of the latecomer shows a sharp upturn of the working-age population, followed by a sharp downturn in a short period. Compared to early-mover countries, the latecomer countries cannot buy more time to accommodate the workable population for the period of demographic bonus and prepare their aging societies for demographic onus. Thus, we conclude that CDT is not necessarily advantageous to developing countries. These outcomes of the latecomer's CDT can be re-interpreted as follows. Developing countries need power sources to pump up economic development, such as the following production factors: labor, physical and financial capital, and economic systems. As for labor, the properties of early maturation and leftward thresholds on DTs of the latecomer mean that demographic movement occurs at an unusually early stage of economic development; this is similar to a plane that leaks fuel before or just before take-off, with the result that it no longer flies higher or farther. What is worse, the property of steeper descent represents the falling speed of a plane so that it cannot be sustained at higher levels, and then plummets to all-time lows.

This study was conducted to collect the basic data to provide for the purpose of the development of dental field. This research is to find the relationship between the level of recognized empowerment of hygienists working in dental clinics and the factors influencing on work achievement in the system of dental clinics. The population of the research is some randomely chosen dental clinics located in Seoul City during the period from March 22 to April 30, 2010, and the sample of 256 female dental hygienists working in the field were recruited as the analysis object group. The data on general characteristics and empowerment were collected by a questionnaire survey. The collected data were analyzed with the SPSS WIN 12.0 program. The following shows the results of this study. 1. The empowerment level of the analysis subject group was 3.63. It is significant statistically that the longer working career or higher annual salary, the higher empowerment level (p<0.05). 2. It shows the high level of empowerment in the group of hygienists who are in education counsel (p<0.01), and who have a permanent job (p<0.05) than others. 3. There is a significant correlation among capability, age, career, annual salary (p<0.01). 4. There is a significant correlation among self determination, age(p<0.05), career (p<0.01), annual salary (p<0.05). 5. In regression analysis, career is proved as one of the significant factors that is related to the empowerment in dental hygienists (p<0.05). This finding shows high level of empowerment in dental hygienists who hold high level of career, annual salary, education counsel jobs, or permanent jobs. Therefore, I suggest with the result of the study that the organization of dental clinic needs to improve its capability and efficiency with the efficient manpower management. Particularly, there need to be various kinds of leadership-trainning and education-program development to enhance empowerment in hygienists as professionals through independent self-decision making experiences and role do experiences.
