바야흐로 국내 인터넷 이용 인구 3,000만명 시대를 눈앞에 두고 있다. 정보통신부의 2003년 하반기 정보화 실태조사에 따르면 국내 인터넷 이용인구는 2002년 12월 기준으로 2,922만명에 달한다. 특히 10대와 20대의 인터넷 이용률은 각각 94.8%와 94.5%에 이른다. 중 장년층의 인터넷 이용률도 꾸준히 증가하고 있다. 인터넷의 이용 용도는 주로 자료 및 정보 검색, 게임, 전자우편등이다. 오프라인 상에서도 존재했던 일상 생활의 일부가 온라인으로 변형돼 옮겨진 셈이다. 이처럼 개인 대 개인은 물론 개인 대 단체, 단체 대 단체간에 이뤄지는 전자우편, 메일링리스트, 메신저, 게시판등 온라인 상에서 발생하는 모든 형태의 의사소통을 가리켜 컴퓨터 매개 커뮤니케이션이라고 한다.

Purpose: To evaluate clinical features and surgical results for rotator cuff tear secondary to shoulder dislocation in middle-aged and elderly patients. Materials and Methods: We reviewed 19 patients over 50 years of age who had rotator cuff tears combined with shoulder dislocation between October 2004 and October 2008. There were 7 males and 12 females with a mean age 64.7 years (range, 50 to 78 years). The average follow-up duration was 22 months (range, 8 to 56 months). We investigated the number of dislocations, the size of the cuff tear, the presence of Bankart lesions and the time interval from dislocation to surgery. We also investigated the ASES score, UCLA score, SST score, and shoulder range of motion before and after surgery. We analyzed clinical outcomes and contributing factors. Results: ASES scores improved from 30.2 preoperatively to 72.3 postoperatively; UCLA scores improved from 12.9 to 26.5; SST scores improved from 2.4 to 7.3. Range of motion improved significantly: forward flexion, abduction, external rotation and internal rotation were, respectively, $110.8({\pm}39.3)^{\circ}$, $107.7({\pm}40)^{\circ}$, $22.5({\pm}17.6)^{\circ}$ and L5 level preoperatively; postoperatively they were $153.6({\pm}20.6)^{\circ}$, $152.1({\pm}20.8)^{\circ}$, $36.4({\pm}22.7)^{\circ}$ and L1 level. Age, the presence of Bankart lesions and the number of dislocations were not correlated with clinical outcomes. But the size of the cuff tear was correlated with clinical results. Also, the duration from dislocation to surgery was correlated with postoperative UCLA and SST scores (p=0.039, p=0.038). Conclusion: For shoulder dislocation, it is important to achieve early diagnoses of rotator cuff tears in middle-aged and elderly patients. If these injuries are both present, early rotator cuff repair should be performed for better clinical results.

To study the ametropia and the sort of glasses, especially progressive multifocal lens, for near purpose on Middle aged & Manhood. 500 adults were tested by the object and subject methods. Among the 500 adults, myopia is 22.4%, hyperopia is 61.4%, and emmetropia is 16.2%, respectively. In test of astigmatism, the amount of astigmatism for the age of forty one to under forty five with-the rule is 28%, the amount of astigmatism against-the rule is 43% and the amount of astigmatism with oblique is 11%, respectively. Whereas, the amount of astigmatism for the age of fifty six to under sixty with-the rule is 10%, the amount of astigmatism against-the rule is 71% and the amount of astigmatism with oblique is 19%, respectively. With-the-rule decreased with increasing age while against-the-rule increased with increasing age. The oblique astigmatism relationship to age could not be determined. The ratio of the progressive multifocal lens was 67.3% for male and 35% for female.

In the era of the 4th industrial revolution, the age of artificial intelligence, the development of ICT technology is having various effects on the online and offline educational environment. The universal access of online education changes the educational paradigm and converts it to a learner-centered service. At the time when a new educational environment is required to change, interest in flip learning is increasing. Even adult learner's online learning needs is also shown very high. The purpose of this study was to investigate how repetitive learning activities through flip learning for middle-aged online learners of K-Cyber University has a relationship and structural relationship between the effects of learning immersion and learning interest on learning satisfaction. Through this study, there is significance in research to suggest direction for learning satisfaction based on flip learning. For further studies, if a model of analysis of various factors that can be measured is specified and applied, it can be used as a research background that can maximize learning satisfaction based on flip learning.

This study was conducted to analyze the difference between positive psychology and citizenship according to the characteristics of urban forest use among middle-aged living in Seoul. In order to achieve the purpose of the study, 156 middle-aged were convenience sampled, and the collected data were subjected to descriptive statistics, variance analysis, and Schéffe post-test using the SPSS 25.0 program. The main research results are as follows. First, gender differences in resilience, optimism, and citizenship were significant, but differences by age were not significant. Second, there were differences in positive psychology and citizenship according to the characteristics of urban forest use. As the average life expectancy increases, social and policy support for the middle-aged population is needed, so it is necessary to actively seek out the diversity of opportunities and methods of urban forest experience to improve the psych-social health of citizens.

The purpose of this study was to promote an understanding of suicidal ideation and identify the factors that influence suicide ideation according to the life cycle of Korean adults. This study was a secondary analysis study using the Korea Health Panel 2016 data. Among adults over 19 years of age, 14,538 people with no missing values in suicidal ideation and influencing factors were classified into young adults (19-39 years old), middle-aged adults (40-64 years old), and the elderly (65 years or over). The data were analyzed by multiple logistic regression. The results showed that 2.9% (108 people) of young adults, 3.2% (181 people) of middle-aged adults, and 3.7% (80 people) of the elderly had suicide ideation over the past year. Factors influencing suicidal ideation by life cycle were anxiety, depression, drug use and quality of life for young adults, subjective health status, stress, anxiety, depression, drug use and quality of life for middle-aged adults. The factors affecting the elderly were body mass index, stress, anxiety, depression, and quality of life. Therefore, factors influencing suicidal ideation should be considered as a major factor for screening risk groups according to the life cycle, and differentiated intervention programs should be developed and provided to prevent and manage suicide in risk groups.
