Currently, Korea is entering an aging society, causing the issues of older adults in a wide range of fields. This study focuses on the health and safety issues of the older adults. As a theoretical background, Maslow's hierarchy of needs theory was applied, and a new theory was established in connection with the physiological needs and safety needs of the 5 stages of desire in relation to the health and safety issues of the older adults. Health issues applying to physiological needs for the older adults are examined in detail in the body, perception and psychology areas, and safety accidents occurring indoors and outdoors are examined in relation to safety needs. Naver DataLab, a big data portal, shows that the number of bugs regarding health and safety of the older adults is steadily increasing. And through Google Trends, we can understand the interest setting up related search keyword about the older adults. According to the related search keywords, social part related to health in health issues is ranked high and kewords related to accident type in safety issues is ranked high. These findings will be an important basis data for research and solution to the issues of older adults.

This study aims to understand the concept of 'ruralism' in Korea by comparing with 'rurality' which were dealt with in various fields related to rural areas in Korea. This study conducted a systematic literature review as a methodology. The process is defining key questions, searching for documents, classifying documents, extracting data, and presenting results. The key questions were set to 'How has the term 'ruralism' been used in various studies?' and 'How can the concept of rurality in Korea be organized?' according to the purpose of the study. The study retrieved literature by searching on Korean academic database, RISS and DBpia, using the five keywords '농촌성', '농촌다움', '농촌다운', 'Rurality,' and 'Ruralism.' The search yielded 1,014 documents which were thereafter screened by systematic literature review process. After sifting, only 31 publications were found suitable for inclusion in the final analysis. This study organized them into four categories: rural concept, rural landscape, rural tourism, and rural development. The literature divided into four types. Type I is a study that deals only with economy·society among studies related to rurality, Type II is a study that deals with both the economic·social and physical environment, Type III is a study that deals with the physical environment of a rural area and presents the rural planning principle as maintenance and preservation. Finally, Type IV is a study that presents ruralism as a new rural planning principle for a future rural area. In the end, the study discussed some implications on defining ruralism in Korea.

With the change of the undergraduate medical education system, many medical schools have recently run or developed a medical education curriculum. The premedical curriculum should be designed according to the sequencing and level of the medical curriculum, but there were no discussions on the standards or evidence for the basic science-related subjects. Therefore, this study examines Physics I, Physics II, Life sciences I, Life sciences II, Chemistry I, and Chemistry II, which are the subjects of need assessment exploration. The need assessment used mean, mean difference, and Borich demand, The locus for focus of memory degree and importance, and the result was converted into 76 keywords. The results of this study are expected to be used as basic data for the development of subjects related to basic science in premedical curriculum.

Purpose: The purpose of this article is to clearly describe research trends on health life expectancy using oral health indicators that have been published from 2010 to 2020 then suggest the direction of future research. Methods: Online academic databases in English (PubMed, Web of Science and Embase) were used to find those articles by applying a variety of keywords, including terms (adjusted life year, adjusted life expectancy, dental and oral). We identified relevant articles based on the following classification method of Mathers: (1) health gaps, (2) health expectancies. Results: Among 1,728 articles from the online databases, the final 13 studies satisfied the inclusion criteria and were selected for analysis. Health life expectancy studies indicate that research growth was recently achieved overseas. Among the literature collected in this study, 10 studies using health gap indicators yielded seven Disability-Adjusted Life Year (DALY), and three calculated Quality-Adjusted Life Year (QALY), which differed in the nature of the survey data used in the study measuring DALY and QALY. There are only three health expectancies and the number of papers were smaller than the health gap study. Conclusion: Establishing a foundation to calculate health life expectancy indicators through the development and improvement of oral health level are needed. More studies in the area of health life expectancy estimation research is based on actual prevalence and oral health-related quality of life are also needed.

A new type of malware that extracts personal and account data over an extended period of time and that apparently is resistant to detection by vaccines has been identified. Generally, a malware is installed on a computer through network-to-network connections by utilizing Web vulnerabilities that contain injection, XSS, broken authentication and session management, or insecure direct-object references, among others. After the malware executes registration of an arbitrary service and an arbitrary process on a computer, it then periodically communicates the collected confidential information to a hacker. This paper is a systematic approach to analyzing a new type of malware called "winweng," a kind of worm that frequently made appearances during the first half of 2011. The research describes how the malware came to be in circulation, how it infects computers, how its operations expose its existence and suggests improvements in responses and countermeasures. Keywords: Malware, Worm, Winweng, SNORT.

Objectives To assess the effectiveness of chuna manual therapy for patients with total knee arthroplasty. Methods We searched 9 electronic databases(KISS, NDSL, RISS, OASIS, KMBASE, Cochrane Library, PubMed, CNKI, Wangfang data) using the keywords 'total knee arthroplasty OR total knee replacement' and 'tuina OR chuna' to identify RCTs that investigated the effectiveness of Chuna manual therapy after total knee arthroplasty. Results 23 RCTs were selected based on inclusion criteria. The systematic review showed positive effect of using chuna manual therapy after total knee arthroplasty. Conclusions 23 studies reported that chuna manual therapy had significant effects on total knee arthroplasty. However, many studies were exposed to probable high risk of bias. Also, all of the studies were published in one overseas country. Therefore, further research is required using well-designed RCTs to support the effectiveness of chuna manual therapy.

Objectives : The purpose of this study is to review the acupuncture treatment for cold hypersensitivity of hands and feet. Methods : We searched articles in 7 search engines with keywords related to 'Cold hypersensitivity of hands and feet' and 'Raynaud disease' in March 2021. Clinical studies that used acupuncture for cold hypersensitivity of hands or feet were included. Animal studies and nonclinical data were excluded. Data on acupuncture treatment such as methods, site, duration, frequency, and period were analyzed. Also, network analysis between acupoints was conducted. Results : Of 41 selected articles, there were 32 case reports, 7 randomized controlled trials, and 2 uncontrolled clinical studies. Studies were conducted using manual acupuncture, electroacupuncture, warm needling, pharmacopuncture, fire needling, and auricular acupuncture. Most studies used more than one acupoint (n=40), and there were 111 acupoints selected for acupuncture treatment for cold hypersensitivity of hands and feet. The most commonly used acupoint was LI11 (n=27). In terms of the correlation of acupoints, LI11 had the highest value of degree centrality at 0.6989. The mean treatment time, number of treatments, and duration were 26.8±8.87 minutes, 15.51±15.75 times, and 77.69±132.80 days. Conclusions : The results of this study could be useful in establishing the evidence for performing standardized acupuncture treatment for cold hypersensitivity of hands and feet.
