Recently, river maintenance is change due to concern for the environment increases. Thus, the river restoration and river environment is best part of river maintenance. In case of Korea, existing river is improvement straightly for flood control and transportation. When the stream channel is straightly, maintain stability is important. Thus, construction of levees along the river. The various river structures for the purpose of flood control and transportation are inhibit factors of longitudinal and lateral connectivity. Connectivity is defined as the maintenance of lateral, longitudinal, and vertical pathways for biological, hydrological, and physical processes. Long-term point of view, increased connectivity is very important for a healthy ecosystem composition. As the first step of river restoration, this study described theory and concept of river continuum and the numerical model was applied to a real topography to simulate the flow analysis with or without segregated and blocked space in the Mankyung river. The results of this study can be utilized to develop the watershed connectivity assessments methods in order to the river restoration.

The main goal of this study was to investigate the factors influencing the life satisfaction of elderly individuals living alone. We analyzed the data obtained in 2016 through "Survey on Residents'Quality of Life in Gyeonggi Province", performing stepwise multiple regression on 824 cases. The results were as follows: First, age, income, and education had a significant impact on life satisfaction, while sex, marital status, and employment had no influence on life satisfaction. Second, as individual-level factors, self-rated health, exercise, and participation in religious activities and social associations had a significant and positive impact on life satisfaction. Third, the results showed that both helping others in neighborhood and trusting people in the neighborhood, between-person factors, positively influenced their subjective quality of life, but receiving help from the neighborhood did not significantly affect life satisfaction. Fourth, satisfaction with cultural facilities, one of the physical environmental factors, was associated with life satisfaction. These results suggest that multi-level factors influencing life satisfaction should be considered to enhance the quality of life of elderly individuals. In particular, they suggest that when planning measures, it is necessary to consider built-environments for the elderly.

Ginsenf Radix (Panax ginseng C. A. Meyer) has been traditionally used as a herbal medicine for many therapeutic or prophylactic purposes in the oriental countries such as Korea, Japan and China for at least two thousand years and also extensively studied in the modern scientific field of chemistry, biochemistry and pharmacology. The herb is now also indicated for use as tonic or a prophylactic and restorative agent for enhancement of mental and physical capacities, in case of weahess exhaustion tiredness loss of concentration, impotence, cold limbs, during illiness anuor convalescence. Ginseng is commonly used in the form of detections, extract and powderl and ginseng products, in the form of capsules tablets and drinks. And also ginseng radix has been widely traditionally prescribed as an important comuonents of manny Chinese prescriptions or alone in various diseases and for health with its different dosages. Nowadays since rinsenf can be generally classified into food or medicine in many nations, it is very difficult to give any exact desnition on the dosage, which may be of particular importance in clinical applications. In addition, the establishment of the reasonable dosage is currently of great significance to meet the demand for such wide applications. Accordingly in this review paper we summarized the dosage of ginseng on the basis of oriental medical books oriental and western pharmacopeias and modern scientific clinical data. The recent survey demonstrated that the averare dosare of finsenf is considered to be three to four grams per day unless prescribed apart, while one to two grams per day in western countries from the western viewpoint of classification of ginseng as a medicine, surrorted by the dosage of not more than one gram per day in most clinical studies. For that reason, it seems likely that the dosage in western countries is ascribed to the safety of ginseng considering side or unwanted effects. Consequently whether the differences of dosage between oriental and western countries depend on dietary habits and races should be closely investigated. Besides, further studies on the pharmacokinetics and bioavailability of ginseng components in clinical trials need to be done to decide optimum dosage of ginseng.

The purpose of this study was to compare cardiopulmonary function, RPE(Rating of perceived exertion), and blood lactate when examining the GXT(Graded exercise testing) of wheelchair treadmill and arm ergometer. Participants were 11 wheelchair basketball players with non disability. While examining the GXT of wheelchair treadmill and arm ergometer, cardiorespiratory functional capacity was measured by using $Quarkb^2$ and Polar and RPE was measured through Borg Scale. The lactate analyser, YSI-2000 was used to measure blood lactate level when resting, right after exercise, two minutes, four minutes, six minutes, and ten minutes of recovery. Data was analyzed by paired t-test using SPSS 18.0 program and significance for all statistical analysis was fixed at .05 confidence level(p<0.05). The conclusion of this study is below. First, maximal oxygen uptake which is a factor of cardiopulmonary function showed the highest with arm ergometer, the rate of respiratory exchange showed the highest with wheelchair treadmill, and maximal heart rate showed the highest with wheelchair treadmill. Second, subjective exercise intensity showed the highest with arm ergometer at the end point. Third, blood lactate level showed the highest with arm ergometer right after exercise.

Objective : The purpose of study is to validate the clinical utility and usability of the Korean version of the Life Space Assessment(K-LSA) which is an assessment tool of community mobility of older adults. Methods : Surveys on the clinical utility and usability of the K-LSA are carried out with a total of aoaa60 occupational and physical therapists. The surveys included the multiple choice questions on the clinical utility and open questions on the usability. Responses to multiple questions are post processed by frequency analysis and technical statistics, and responses to the open questions are categorized by common factors in each questions. Results : Average value of clinical utility ranges from 3.6 to 4.0 with positive responses of 'fair (3 point)', 'agree (4 point)' and 'strongly agree (5 point)' being 95~100%. Average value for clinical usability ranges from 3.6 to 4 with positive answers of 'fair (3 point)', 'easy (4 point)' and 'very easy (5 point)' being 88.3~100%. Additionally out of open-type questions of clinical usability, it was pointed out that the concept of 'neighborhood' for the life space level 3 and 4 is unclear. Conclusion : The current study and research outcomes showed that the K-LSA is a validated tool in Korean health care system for the clinical utility and usability in measuring community mobility, and that it is straightforward in practical use. It will help clinicians and therapists promote the social participation of older adults, and set an intervention goal for enhancing community mobility. It will further help clinicians and researchers in education and research for medical intervention and goal-setting.

The purpose of this study was to suggest the effective squat exercise position to strengthening vastus medialis oblique, and vastus lateralis in quadriceps. Subjects were twenty patients with patellofemoral pain syndrome (PFPS) volunteered to participate in this study. All subjects were applied to static squat convergence exercise with knee flexed $45^{\circ}$, $60^{\circ}$, and $90^{\circ}$ for 30 seconds total 5 times. Measurement variables were maximal voluntary isometric contraction (MVIC) of the quadriceps, Q angle and length of thigh. Those were measured before and after the squat exercise on knee joint angle, change rate of which were used for statistical analysis. As a result, squat exercise with knee flexed $90^{\circ}$ increase significantly among knee joint angle in the MVIC change rates of quadriceps (p<.05), however the rates of Q-angle and length change of thigh showed no significant difference. Therefore, this findings suggest that squat exercise with knee flexed $90^{\circ}$ strengthen quadriceps effectively in patients with PFPS.

The objective of this study was to improve the sensory qualities of soymilk. For this purpose, soymilk was prepared by adding different types of rice grain, including cooked, puffed, and saccharified rice. Acceptable products could be obtained by addition of saccharified rice. The addition of saccharified rice had a positive influence on sensory qualities, especially mouth feel. Further, soymilk with saccharified rice was comparable in terms of physicochemical characteristics (pH, soluble solids, and viscosity) with commercial whole-bean soymilk. This result suggests that there are opportunities to develop a new market for soy-milk that incorporates health benefits and traditional beverages.
