Purpose: The purpose of this study is to provide basic evidence on the need to approach osteoarthritis patients through a psychological factors-considering rehabilitation program by understanding how activity restrictions in osteoarthritis affect health-related quality of life and depression. Methods: This study assessed 3,761 osteoarthritis patients from the Korea National Health and Nutrition Examination Survey. The subjects were divided into two categories: with and without activity restriction. Results: The prevalence of osteoarthritis in women was higher than that of men (men: 19.7%; women: 80.3%), and high BMI increased the prevalence of osteoarthritis. The EQ-5D index of subjects with activity restriction was 0.84±0.18 (points), while in those without activity restriction was 0.93±0.12, and the diagnosis of depression was 15.8%, 8.2%. There was a statistically significant difference in the odds ratio for each item in the EQ-5D. Moreover, the odds ratio for depression with activity restriction was 2.098 compared with no activity restriction. Conclusion: Activity restriction of osteoarthritis patients significantly decreases the health-related quality of life and increase the probability of depression. Therefore, early diagnosis of depression symptoms to prevent deterioration of symptoms in patients with osteoarthritis and to increase compliance with rehabilitation treatment, and to provide arbitration, including treatment that can alleviate depression.

Bridges are exposed to very severe environment and experience, as service life increased, elevated traffic load and traffic flow, in addition to natural disasters. In comparing to other road structures, bridges may cause more significant damage, such as human-involved accidents, to the society in the event of collapse. A certain level of service shall be necessarily secured to assure the minimum safety of users. The cost for manage and preserve bridges will increase gradually and more restrictions will be loaded to efficiently distribute the limited resources, such as monetary budget and human resource etc. In order to enhance performance and serviceability of bridges with the limited resource, asset management technique has been applied into the bridge management system, which capitalizes the road infrastructures including bridges and assess them in accordance with the government finance report. In the application of asset management, there must be a tool for assess the performance of bridges and this study introduces the basic information on the definition and role of performance measures for asset management for bridges. This research suggests future development direction of performance measure for asset management for bridges in Korea.

The number of fires in the Korean distribution warehouse increased by about 350 from 1,070 in 2014 to 1,416 in 2020. In addition, the fire load increases with the scale of the distribution warehouse, and even if the automatic sprinkler operates, there is a limit to the direct intrusion of the water source into the ignition source, and the detector is often installed on a high ceiling. The sensing time is often delayed. In order to improve the fire safety of such distribution warehouses, the US NFPA stipulates in detail the contents related to the facility, such as sprinkler water discharge standards, rack-type warehouse installation height restrictions, and regulations on collection and equipment. However, in Japan, the goods loaded inside the distribution warehouse are not classified in detail, and it is considered that the fire safety for the distribution warehouse is low due to the relaxation regulations of the fire prevention section. Therefore, in this study, common problems are classified into material, spatial, and safety management characteristics through the cases of distribution warehouse fires that occurred in Korea and abroad, and the problems related to distribution warehouses in Korea and abroad are compared and analyzed. And present basic materials for improving the life safety standards of future distribution warehouse facilities.

The purpose of this study is to survey middle school students’s awareness of sexuality and relationships with the opposite sex. The students need to have at their disposal basic resources on sexuality education and an established and systematic curriculum. To achieve this result, questionaires were distributed to 640 students who were chosen randomly in three middle schools in Seung-ju Goon and Goo-rye Goon in Chonnam area, 573 questionaries were used for the final analysis. The results were as follows： In the area of awareness of sexuality, male students regarded sex more positively than female students. It also showed that 19.9% or male students and 17.6% of female students were not aware of their virginity. Male students said they felt sexual impulses most when they saw naked women, and secondly, by sex magazines. This indicates students are motivated mostly by outside influences. There is a considerable gap in the degree of sexual knowledge between male and female according to their school year and father’s family education level. However, little difference is seen according to student’s family circumstance, father’s education level. However, little difference is seen according to student’s family circumstance, father’s job, and student’s religion and vise versa. School restrictions were so severs that 48.2% of boys and 47.1% of girls said that schools paid little attention to their needs. The school restricted rather than permitted relationships with opposite sex. Most of the students revealed a dissatisfaction with the school sexuality education program. Because of confucianism, Korean society has a negative attitude towards sexual activity including sexual education in the schools. 56.8% of male students and 81.4% of females students wanted female teachers to be their sexuality education teachers or advisors rather than male teachers, and 44.8% of male students and 51.2% of females students wanted to receive sexuality education in their Home Economics classes. Materials for sexuality education were considered most effective through videos and audio-visuals. As a result, this survey showed that there appeared to be a great need for a sound, effective, and sensitive sexuality education curriculum in the middle schools for teenagers. It should be conducted in such a way that the teenagers will learn about their sexual needs, their gender differences, and understand and know how to conduct themselves in today’s society sexually.

To give satisfaction with the fit to a wearer, the wearer's body size and body types should be considered first, this study conducted the descriptive statistical analysis on the upper body measurements of women in their 20s because their body shape has reached the completion stage of adult female's physical development. Also, the analysis classified their upper body types into groups to secure basic data for (maximum satisfaction with the fit of ready-to-wear clothing. The factor analysis was conducted using 49 items of measurement. The main factor analysis was used as a factor extraction method. After extracting the factors with Eigenevalues over 1, the factor loadings were drawn using the Varimax rotation. As a result, 6 factors were extracted. To secure internal consistency, factors that could lower the reliability of the experiment were taken out, so only 36 of the 49 items were used for the analysis. After selecting the items to recognize the main features of each body type, they were used for the final factor analysis. The entire R square of the 6 factors was 84.06%. To classify the upper body types of women in their 20s and to recognize the main features of each body shape type, the researcher conducted the cluster analysis with the items generated from the factor analysis. Through the cluster analysis, the upper body type of women in their 20s were classified into 3 body types. Also, since there are some restrictions on this research objects in terms of local and numbers of measured objects, the results of the this research should only be used as basic data.

한국전자통신연구원에서 개발한 NanoQplus는 센서 네트워크 운용을 위한 임베디드 운영체제로, 프로그래머에게 친숙한 다중 쓰레드 프로그래밍 환경을 제공하지만 잘 알려진 TinyOS와 같은 운영체제와 비교해볼 때 네트워크 프로토콜 스택이 빈약하다는 단점이 있다. 본 논문에서는 Internet Engineering Task Force (IETF)에서 표준화 중인 Dynamic MANET On-demand (DYMO) 라우팅 프로토콜을 NanoQplus에 적용해본다. DYMO 프로토콜은 본래 이동 애드혹 네트워크에 적합하도록 제안된 라우팅 프로토콜이며, 이동 애드혹 네트워크는 무선 센서 네트워크에 비해 자원의 제약에서 자유로우므로, 기본 DYMO 프로토콜을 아무런 수정 없이 무선 센서 네트워크에 적용하기는 힘들다. 게다가 매체 접근 제어 계층과 네트워크 계층 사이에 존재하는 중복되는 데이터를 줄이기 위해 두 계층 프로토콜간의 결합도도 고려할 필요가 있다. 따라서 우리는 DYMO 기본 명세를 수정하여 NanoQplus에 적합토록 수정하였다. 실제 센서 노드에서의 실험 결과를 통해 NanoQplus에 기반을 둔 DYMO 프로토콜이 무선센서 네트워크 시나리오에서 효율적으로 동작함을 알 수 있었다.

Lack of knowledge and digital skills is a threat to the information security of the state and society, so the formation and development of organizational culture of information security is extremely important to manage this threat. The purpose of the article is to assess the state of information security of the state and society. The research methodology is based on a quantitative statistical analysis of the information security culture according to the EU-27 2019. The theoretical basis of the study is the theory of defense motivation (PMT), which involves predicting the individual negative consequences of certain events and the desire to minimize them, which determines the motive for protection. The results show the passive behavior of EU citizens in ensuring information security, which is confirmed by the low level of participation in trainings for the development of digital skills and mastery of basic or above basic overall digital skills 56% of the EU population with a deviation of 16%. High risks to information security in the context of damage to information assets, including software and databases, have been identified. Passive behavior of the population also involves the use of standard identification procedures when using the Internet (login, password, SMS). At the same time, 69% of EU citizens are aware of methods of tracking Internet activity and access control capabilities (denial of permission to use personal data, access to geographical location, profile or content on social networking sites or shared online storage, site security checks). Phishing and illegal acquisition of personal data are the biggest threats to EU citizens. It have been identified problems related to information security: restrictions on the purchase of products, Internet banking, provision of personal information, communication, etc. The practical value of this research is the possibility of applying the results in the development of programs of education, training and public awareness of security issues.

The relevance of the research involves outlining the need for modern professionals to acquire new competencies. In the conditions of rapid civilizational progress, in order to meet the requirements of the labor market in the knowledge society, there is a readiness for continuous training as an indicator of professional success. The purpose of the research is to identify the impact of various forms of application of information technologies for lifelong learning in order to provide the continuous self-development of each person without cultural or age restrictions and on the basis of rapid digital progress. A high level (96%) of need of the adult population in continuing education with the use of digital technologies has been established. The most effective ways to implement the concept of "lifelong learning" have been identified (educational camps, lifelong learning, mass open online courses, Makerspace activities, portfolio use, use of emoji, casual game, scientific research with iVR game, implementation of digital games, work in scientific cafes). 2 basic objectives of continuing professional education for adults have been outlined (continuous improvement of qualifications and obtaining new qualifications). The features of ICT application in adult education have been investigated by using the following methods, namely: flexibility in terms of easy access to ideas, solving various problems, orientation approach, functional learning, group or individual learning, integration of leisure, personal and professional activities, gamification. The advantages of application of information technologies for continuous education (economic, time, and adaptive) have been revealed. The concept of continuous adult learning in the context of digitalization has been concluded. The research provides a description of the structural principles of the concept of additional education; a system of information requests of the applicant, as well as basic technologies for lifelong learning. The research indicates the lack of comprehensive research in the relevant field. The practical significance of the research results lies in the possibility of using the obtained results for a wider acquaintance of the adult population with the importance of the application of lifelong learning for professional activities and the introduction of methods for its implementation in the educational policy of the state.
