  • The purpose of this study was to provide a foundation for the methods of stretching in sports activities. The subjects were normal adults, the applied exercise was dynamic and static stretching and the research methods were measuring the jump height and muscle activity during jumping with subsequent data comparison and analysis. Twenty normal adults were randomly divided into 2 groups, and each group performed dynamic or static stretching. Jump height and the vastus lateralis and gastrocnemius muscle activities were measured during jumping, which was performed immediately before and after stretching. Statistical analysis was performed using an analysis of covariance. The results indicated that dynamic stretching was more effective than static stretching with respect to both jump height (p<.05) and muscle activity of the vastus lateralis (p<.05). Consequently, it was believed that dynamic stretching should be applied as a warm-up exercise for athletes who need to build and maintain high muscle strength.

  • As we enter the era Convergence, commercialized convergence contents aimed at the disabled are giving a lot of help to them. This fusion research is aimed at providing necessary basic data and practical measures for these by analyzing the effect of influencing the quality of life for women with disabilities. This research was conducted with 250 disabled women living in Jeon-nam region from Jan,1 through April, 25 in 2015. After screening women aged 20-80 who had symptoms and musculoskeletal disorders and were using convergence contents, convergence projects were implemented with total 125 patients over 16 weeks. The result of the convergence projects showed that most of these experieced the decrease of musculoskeletal pain, the decrease of depressed levels, and the improvement of quality of life. Future studies should be done in terms of a long-term perspective and continuing support, and follow-up studies should also be done to evaluate its effectiveness.

  • The purpose of this study was to identify the relationship between depression and physical health of the elderly and to provide fundamental data for programs which improve the health of this population. The subjects were 168 elderly people(55 years and older) who resided at home in Taegu. They were surveyed by interview using a closed- ended questionnaire. The survey was done from September 16 to October 16 in 2000. The instruments used in this study were general characteristics, Short form Geriatric Depression Scale(SGDS), Barthel Index, Muscular skeletal symptoms scale, Northern Illinois University's Health Self Rating Scale. The data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, multiple regression with SPSS PC 10.0 version for Windows. The findings were as follows: 1. As compared 65-74 years elderly group, 75-84 years group was significantly higher score for depression(F=3.17, p=.026). As compared elderly group who has own spouse, the group who has no own spouse was significantly higher score for depression(t=- 2.44, p=.016). 2. The aged who have more limitation of Activities of Daily Living(ADL)(t=3.93, p=.000), pain of muscular skeletal symptoms(F=5.33, p=.002) and poor perceived health state(F=17.04, p=.000) showed the higher severity of depression than the aged who have not. 3. ADL correlated negatively with depression(r=- .293, p=.000), pain of muscular skeletal symptoms correlated positively(r=.251, p=.001), perceived health status correlated negatively(r=-.522, p=.000). 4. The combination of perceived health status and ADL explained 29.1% of the varience of depression. On the basis of the above findings the following recommendations are made; 1. Developing health programs is needed considering ADL, pain of muscular skeletal symptoms, perceived health status, demographic variables (age, spouse status) which have an significant effects on depression of the elderly. 2. In the following study, the use of the various scale is needed which reflects physical status of the elderly in home.

  • This study was to identify the prevalence rate of the limitation of activity, the reasons for activity limitation, association with activity limitation and general characteristics among older adults in Korea's population. Data were extracted from the $7^{th}$ Korea National Health and Nutrition Examination Survey. The number of participants were 1,578 older adults who aged 65 years over. SPSS program (version 18.0) was used for analyzing on frequency, Chi-square test, and logistic regression analysis of the data. The total prevalence rate of activity limitation among Korea's population was 19.6% in 2016. The prevalence rate of the reasons for activity limitation in Korea was highest for neck and back problems(19.8%), followed by arthritis and rheumatism(17.1%). The prevalence rate of activity limitation was statistically significant associated with age and education level, respectively. In conclusion, Age, educational level, and musculoskeletal diseases such as problems related to back and neck, arthritis and rheumatism could be significant risk factors for activity limitations in older adults who aged 65 years over. These findings could be useful as evidence-based data for relieving the prevalence rate of activity limitation and the prevention and management of activity limitations in Korea population.

  • 근골격계 질환은 다른 질병과는 달리 직업적 특성 때문에 발생하는 질환자수가 많고 집단적으로 발생한다. 질환들의 예방활동은 단순하게 접근하거나 또는 1회 적인 예방활동으로는 원천적인 예방이 어려우므로 품질관리 시스템과 환경경영시스템을 참고하여 지속적인 관리와 더불어 조직적인 관리가 이루어 져야 한다. 이러한 목적을 달성하기 위해 사업장의 인간공학 관리시스템을 12가지 기본요소(방침 및 리더십, 조직, 계획, 책임, 평가 예방과 관리, 교육과 훈련, 의사소통, 규칙 및 절차, 내부 검사와 감사, 사고/질병 조사, 문서와 기록관리, 프로그램 평가)로 세분화하여 시행하였다. 이를 이용하여 pallet 적재방법, key hole 가공작업방법, 기판 수삽입 작업대 등을 개선한 사례를 제시하였다.

  • 최근 들어 근로자의 이동시간 단축을 통한 에너지 절감뿐만 아니라 저출산 고령화에 따른 노인 인구의 경제활동 유도, 출산여성에 대한 경력단축 방지, 장애인에 대한 근로활동 제공 등을 위한 근로 환경의 변화가 요구되고 있다. 이러한 근로환경을 제공하기 위한 스마트워크는 기존 사무실에서 근무하는 환경을 탈피하여 댁내, 스마트워크 센터, 또는 이동 중에도 마치 직장에서 근무하는 것처럼 업무를 효율적으로 수행할 수 있는 환경을 제공한다. 스마트워크는 현재 사용중인 여러 가지의 기술들을 근로환경에 맞게 채택하여 구현할 수 있으며, 특히 근로자의 업무 생산성을 높이기 위한 협업기능이 제공될 필요가 있다. 영상협업 기능은 영상, 음성 및 콘텐츠 공유를 통해 원격지 간에 효과적인 업무를 수행할 수 있도록 제공하는 기능이다. 본 논문은 스마트워크에서 영상협업을 제공하기 위하여 요구되는 상호연동 기능확장을 위한 표준화 이슈에 대하여 기술한다.

  • A safe working environment is an important and crucial factor in the operation of a firm, and is also essential for logistics companies in supply chain management. This study confirmed that the safety climate and safety prevention activities have a positive relationship with safety behavior from the perspective of domestic small and medium-sized logistics companies that continue their business relationships by signing contracts with large logistics companies. In addition, the moderating role of regulatory uncertainty and competition uncertainty in the previous positive relationship was empirically examined.

  • This study aims to examine and analyze the operations and activities of Friends of Libraries groups in foreign countries. Friends of Libraries are groups of people who are voluntarily associated in order to assist libraries in their work. They have been involved with various libraries in many countries for almost a century. They support libraries by raising funds, working as volunteers, performing P.R. activities, operating political campaigns and being involved in the community. Nowadays. Friends groups are considered more important than at any time in their history because they provide such diverse support. Thus, new groups are being established in many countries. This study suggests that the establishment of Friends groups could improve library operations and services in Korea.

  • In this study, we revisit an empirical literature has found that neighborhood income inequality lowers people's likelihood of contributing public goods in terms of volunteering. We contribute to the literature by explicitly addressing the issues of larger and improper neighborhood choice with a census-type data and endogenous neighborhood location with some unique features of 2009 Social Survey Data by Statistics Korea. The results have confirmed that income heterogeneity lowers people's volunteering.

  • 바다는 자원의 보고로서 많은 수산업 활동을 통환 경재활동이 활발히 이루어 지고 있으나 기상 등의 해양환경에 많은 영향을 받고 있다. 이 때문에 자동화된 해양 환경 분석 및 예측 기술에 대한 연구가 활발히 진행 되고 있다. 현재 국내에서 수산업 활동에 영향을 미치는 해양 재해로는 기름 유출에 의한 해양오염의 피해, 적조에 의한 수산업의 피해, 해양환경 이변에 의한 수산업 및 재해 피해 등 이외에 다양한 피해가 있다. 해양 환경 자료의 수집과 수집된 자료를 분석하여서 해양재해를 예측하면 이들의 피해를 최소화하는데 기여할 수 있다. 그러나 국내 해양 환경에 대한 조사 및 분석 연구는 미흡한 편에 있다. 이에 본 논문은 국내의 원해 및 근 해역에서 수집된 해양 환경 자료를 분석하여 해양 재해를 예측할 수 있는 시스템 클라우드 기반의 해양재해 예측 시스템을 연구한다.
