Objectives: The purpose of this study is to report the effectiveness of Korean medicine treatment on postoperative state patients with cervical spinal cord injury due to ossification of the posterior longitudinal ligament. Methods: A 55-year-old Korean male patient diagnosed with cervical spinal cord injury due to ossification of the posterior longitudinal ligament was treated in an inpatient setting with Korean medicine treatment consisting of herbal medicine, acupuncture, and others from May 22 to August 21. The outcome was evaluated with the American Spinal Injury Association Impairment Scale (AIS), Spinal Cord Independence Measure-III (SCIM-III), modified Japanese Orthopaedic Association scale (mJOA), Numeric Rating Scale (NRS) before and after, or during the treatment period. Results: After 92 days of treatment, the patient's scores on all scales improved. Conclusion: The results suggest that Korean medicine treatment may be effective for postoperative patients with cervical spinal cord injury due to ossification of the posterior longitudinal ligament. Further studies should be conducted on a larger number of patients.

The application method of GIS for planning of forest road network can be save the efforts and cost by frequently change of forest road and evaluation the forest road route before construction. The purpose of this study is to suggest the proper method for planning an optimal forest road network in mountains forest using geographic information system(GIS) in the national forest of Mt. Kumsan at Namhae-gun, Gyungsangnam-do. In the forest road network planning by the minimum longitudinal gradient, The total length was 20.41km, and road density was 6.92m/ha. In the forest road network planning by mixed with the minimum longitudinal gradient and the maximization of investment effect, The total length was 21.15km, and road density was higher than that of the minimum longitudinal gradient as 7.17m/ha. The road length overlapped by cost path was more short than 3.52m/ha of the minimum longitudinal gradient as 1.73km. So, it appeared that forest road has an high effectiveness in yarding function. Therefore, it considered that the geographic information system could provide an effective and resonable solutions for planning of optimal forest road network.

Unlike previous studies, this study looked at the effect of the ideological tendencies of local government heads on the social welfare budget as a longitudinal study. This study was made possible by the election of the head of a progressive group in Gumi-si, a stronghold of conservatives, after the implementation of the local self-government system. Therefore, in this study, the change process of the political ideological orientation of Gumi-si's heads and the social welfare budget by year were listed and time-series analysis was conducted using actual cases of Gumi-si, Gyeongbuk for more than 12 years. As a result of the analysis, first, as in the cross-sectional analysis, in the longitudinal study, the change in the rate of increase in the social welfare budget according to the political ideological tendencies of the head of the local government showed a meaningful difference. Second, as in the previous cross-sectional analysis, the social welfare budget increased in the year before the election. Third, the same change in the growth rate as in the second did not appear at the end of the third elected term. All studies on the relationship between the political ideological tendencies of local government heads (including local councils) and the social welfare budget have been cross-sectional. However, this study has great implications in terms of the results of the first longitudinal cross-sectional analysis.

Leisure is an important role on happiness and health in midlife. Nevertheless, there has been little research using a longitudinal method in Korea to identify the influence of leisure on happiness and health. Current study examined the effect of leisure satisfaction and time for leisure activities on happiness(SHS) and health-related variables(psychological symptoms, physical symptoms, and quality of sleep) in middle aged adults(40-65 years) by longitudinal data. Two surveys were conducted with 10 months' interval and total 145 respondents(M=49.45) participated in both surveys. Hierarchical regression analysis was employed to investigate that both leisure satisfaction and time for leisure activities in the first time have an effect on happiness and health-related variables in the second time after controlling for each happiness and health variables in the first time as well as demographic variables. We found that leisure satisfaction influenced beneficially on happiness(SHS), psychological symptoms, and quality of sleep after 10-month. Similarly, time for leisure activities had effect on happiness(SHS), psychological symptoms, and physical symptoms after 10-month. The implication for study were discussed.

Objective: This study investigates the impact of multimorbidity on work through a literature review of longitudinal studies. Methods: A systematic review was carried out in the databases Lilacs, SciELO, PAHO, PubMed/Medline, Scopus, Web of Science, and Cochrane. There were no restrictions regarding the year of publication or language to maximize the identification of relevant literature. The quality of studies was assessed by the protocol STrengthening the Reporting of OBservational studies in Epidemiology (STROBE). Results: An initial database search identified 7522 registries, and at the end of the analysis, 7 manuscripts were included in the review. Several studies have demonstrated direct and indirect impacts of multimorbidity on the health of workers. For this, the number of missed days due to health-related issues was evaluated, as well as the reduction in work productivity of the unhealthy worker, vulnerability of the worker with multimorbidity regarding higher indices of dismissal and recruitment difficulties, and incidence of early retirement and/or receipt of benefits due to disabilities. Conclusions: Multimorbidity has a negative impact on work, with damages to quality of life and work productivity, worsening the absenteeism/presenteeism indices, enhancing the chances of temporary or permanent leaves, and lowering employability and admission of individuals with multimorbidity.

The present study developed teaching-learning activities to improve personal intelligences and to investigate their effectiveness. Significant differences were found in both interpersonal and intrapersonal intelligence. Positive effects appeared in cooperative attitudes, capacity to care for and understand others, and in reflective thinking abilities. The results suggest the importance of a balanced educational curriculum in order to enhance human affective aspects, self-esteem, cooperative classroom climate formation and the moral and character development of students. Consistent and systematic investigation is needed on multiple intelligences theory, development of teaching-learning activities, their longitudinal effects, and a fair assessment instrument.

Purpose: The purpose of this study was to examine the effects of physical, psychological, and social factors on the health status of patients undergoing hemodialysis using longitudinal data. Methods: Two surveys were conducted within a period of two-year. A total of 75 patients participated in both surveys. Eight variables including symptoms, treatment belief, hope, meaning-focused coping, family support, friend/peer support, healthcare provider support, and health status were measured. Data were analyzed by paired t-test, Pearson's correlation coefficients, and hierarchical multiple regressions. Results: The mean age of the participants was 47.31 and the average duration of dialysis was 8.27 years. There was no difference in scores on perceived health status between the two year-interval surveys. The two-year follow-up on perceived health status was correlated with baseline perceived health status, friend/peer support, meaning-focused coping, hope, and symptoms. As the result of the regression analysis, friends/peer support (${\beta}=.31$, p=.013) and baseline perceived health status (${\beta}=.30$, p=.020) were found to be significant predictors of subsequent health status which explained 39.0% of the variance. Conclusion: This study suggests the importance of psychosocial resources for positive health outcomes in patients with a chronic illness. Nursing interventions aimed to provide renal peer support need to be developed and tested.

This paper presents a control effectiveness analysis of the hawkmoth Manduca sexta. A multibody dynamic model of the insect that considers the time-varying inertia of two flapping wings is established, based on measurement data from the real hawkmoth. A six-degree-of-freedom (6-DOF) multibody flight dynamics simulation environment is used to analyze the effectiveness of the control variables defined in a wing kinematics function. The aerodynamics from complex wing flapping motions is estimated by a blade element approach, including translational and rotational force coefficients derived from relevant experimental studies. Control characteristics of flight dynamics with respect to the changes of three angular degrees of freedom (stroke positional, feathering, and deviation angle) of the wing kinematics are investigated. Results show that the symmetric (asymmetric) wing kinematics change of each wing only affects the longitudinal (lateral) flight forces and moments, which implies that the longitudinal and lateral flight controls are decoupled. However, there are coupling effects within each plane of motion. In the longitudinal plane, pitch and forward/backward motion controls are coupled; in the lateral plane, roll and side-translation motion controls are coupled.
