The purpose of this study is to assess construct validity and verify the concept of the Happiness-enhancing Activities and Positive Practices Inventory(HAPPI) developed by Henricksen & Stephens(2013), for Korean old adults who participating physical activities with measuring happiness-related propensity. In this study, the research model was confirmed by evidenced based on the content validity, EFA, construct validity of the latent structure analysis with CFA, reliability as internal consistency. Using self-reported questionnaire conducted among 370 participants who physical activities. Total of 344 data were selected. As a result, internal consistency α was acceptable. Evidence-based on convergent and discriminant of the CFA as GFI=.925, CFI .962, TLI .953, and RMSEA .062 appeared significantly. Model goodness-of-fit, C.R. ratio(Critical ratio: estimates/SE) and Squared Multiple Correlations(SMC), and average variance extracted(AVE) was verified with the hypothesis of the model. Therefore, HAPPI validity evidence for the model fit was confirmed. In conclusion, the HAPPI 4 factors and 16 items(Other-focused, Personal recreation and interests, Achievement, Self-Concordant Work, Spiritual and thought-related) has reliable evidence to apply for Korean old adults and applicable assessment of happiness.

The purpose of this study was to evaluate the importance and satisfaction level foreigners place on human and physical evidence service in Korean restaurants based on nationality such as American/European, Japanese, Chinese, and Southeast Asian. The research was performed by using questionnaires conducted from August to September on 365 foreigners living in Busan. Total mean scores for the importance (3.96/5.00) and satisfaction (3.33/5.00) of Korean restaurant human and physical evidence service were significantly different (p<0.01), as the gap was -0.63. The mean scores of the gap were -1.03 for cleanliness of dining area, -1.01 for cleanliness of tableware, and -0.95 for easily understandable menu board. The mean scores of satisfaction for Southeast Asian individuals (3.77) were significantly (p<0.01) higher than those of American/European (3.40), Chinese (3.37), and Japanese (2.81). The importance and satisfaction grid showed that an easily understandable menu board and a brief description of the food or menu scored high for the importance and low for the satisfaction in American/European, Chinese, and Japanese individuals. Cleanliness of the dining area, cleanliness of tableware, cleanliness of staff appearance, kindness of employees, rapid resolution of complaints, and prompt and quick service scored high for importance and low for satisfaction in Japanese. However, Southeast Asians were satisfied with human and physical evidence service of Korean restaurants.

Objectives : This study aimed to investigate the present status of physical therapies provided in the Korean medicine clinics, and to find out the priorities among and the estimated fees of physical therapies for the National Health Insurance plan. Methods : We administered nationwide survey to Korean medicine doctors using the on-line survey system. 16 physical therapies were listed in the Web-based questionnaires, and responders were asked to mark the therapies they used for their patients, and, for each therapy they marked, to fill in the form including the frequencies of service, service fees, target diseases, and priorities for health insurance coverage, etc. Results : Of 488 respondents, 93.7% provide more than one physical therapy for their patients, and each responder uses 5.9 physical therapies on average. 60-90% of physical therapies are being given to patients for free because they are not covered by the National Health Insurance. There is little evidence that the specialties of Korean medicine doctors are related with the use of physical therapies, but, in some therapies, the doctors with longer career years use the physical therapy more frequently. Most physical therapies are applied to the patients with musculoskeletal diseases, cardiovascular diseases, and nervous diseases, etc. Conclusions : Physical therapies are widely used among Korean medicine doctors without proper compensation. This could be the one of the main factors distorting the profit structure of Korean medicine clinics, and it encourages the National Health Insurance to cover physical therapies provided in the Korean medicine clinics.

Objectives: After many national physical activity guidelines have established, recent changes are deep and rapid. So the major features and implication to reverse worsening Korean physical activity indicator is desprate but related knowledge and informations are few. So review of recent features and implications of new physical activity guidelines have made. Methods: National physical activity guidelines of advanced countries were searched through snowballing methods. Major features were described according to the nation. Implication were drew through discussion for Korean realitiy. Results: New Australian physical activity and sedentary behaviour guideline explicitly included sedentary behaviour. The age in the guideline expanded to early years. Canada also presented 24-hour movement guidelines to early years. The second generation of the physical activity guidelines reflects the extensive amount of new knowledge. New aspects include discussions of additional health benefits related to brain health, additional cancer sites, and fall-related injuries; immediate and longer term benefits for how people feel, function, and sleep; further benefits among older adults and people with additional chronic conditions; risks of sedentary behavior and their relationship with physical activity; elimination of the requirement for physical activity benefits to occur in bouts of at least 10 minutes; and tested strategies that can be used to get the population more active. Conclusions: The most important message from the new guidelines is that the greatest health benefits accrue by moving from no, to even small amounts of, physical activity. Multiple studies demonstrate that the steepest reduction in disease risk occurs at the lowest levels of physical activity. People need to understand that even small amounts of physical activity are beneficial and that reductions in the risk of disease and disability occur by simply getting moving. So various evidence based proven strstegies are needed in Korea including workforce training.

Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. The central nervous system deals with stabilization of the spine by contraction of the abdominal and multifidus muscles in anticipations of reactive forces produced by limb movement. Recent evidence indicates that the lumbar multifidus muscle and transversus abdominis muscle may be involved in controlling spinal stability. Stabilization training in neutral spine is an integrated approach of education in proper posture and body mechanics along with exercise to improve strength, flexibility, muscular and cardiovascular endurance, and coordination of movement.

This article reveals the relationship between the body characteristics of the elder people and the size of park facilities during utilization of parks by scientific investigation. The experiment involves 540 elder people, and offer concrete evidence for park design in ageing society. These evidences mainly consists of the following aspects: First, the relation between physical situation of elder people and their using parks. Secondly, the relation between the hearing status and exchange circle diameter in elders. The last is the relation between the distance visual acuity and designing the scene. Finally we get the most suitable step length range, stairs height, road slope, communication space diameter and general formulas about the best vision distance for elder people.

The physical models are useful to understand the soil behaviour. Hence, these tools allow validating analytical theories and numerical data. This paper addresses the design, construction and implementation of a physical model able to simulate the soil liquefaction under different cyclic actions. The model was instrumented with a piezoelectric actuator and a set of transducers to measure the porewater pressures, displacements and accelerations of the system. The soil liquefaction was assessed in three different grain size particles of a natural sand by applying a sinusoidal signal, which incorporated three amplitudes and the fundamental frequencies of three different earthquakes occurred in Colombia. In addition, such frequencies were scaled in a micro shaking table device for 1, 50 and 80 g. Tests allowed identifying the liquefaction susceptibility at various frequency and displacement amplitude combinations. Experimental evidence validated that the liquefaction susceptibility is higher in the fine-grained sands than coarse-grained sands, and showed that the acceleration of the actuator controls the phenomena trigging in the model instead of the displacement amplitude.

We present NIR spectroscopic data of young radio quasars obtained from Flamingos-2 (F2) at Gemini-South. The targets are originally selected from Wide-Field Infrared Survey Explorer survey in combination with radio survey data, such as FIRST and NVSS. Our goal is to find observational evidence of jet-driven outflows, which is expected to be present in young luminous quasars from the theoretical studies. While 16 targets were observed with F2, narrow emission lines ([O III] or Hα) were detected in 7 targets. FWHM of the emission lines (up to 2500 km/s) were remarkably broad compared to ordinary quasars, revealing the presence of strong outflows. The black hole mass estimated from Eddington limit ranges from ~108 to 109 solar mass, indicating that the target quasars are likely to be progenitors of massive galaxies. Finally, we present the comparisons between the outflow velocity and the physical properties of radio jets derived from the VLA radio imaging data, in order to investigate the physical connection between the ionized outflows and radio jets.

Objective: This study aimed to assess the effectiveness of a balance training program in improving balance and functional independence to reduce fall risks among community-dwelling elders. Design: A multi-center randomized controlled trial Methods: A total of 66participants were randomly assigned to a balance training group or a control group. The balance training program, conducted three times a week for 32 weeks, included warm-up exercises, main balance training exercises, and cooldown stretch exercises. Outcome measures included the Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), and Modified Barthel Index (MBI). Results: The balance training group demonstrated significant improvements in all outcome measures, indicating enhanced balance, improved functional mobility, and increased independence in activities of daily living. In contrast, the control group showed only slight improvements in BBS, TUGT and MBI scores. Conclusions: These findings provide evidence supporting the effectiveness of balance training programs in reducing fall risk and promoting health and wellbeing among community-dwelling elders. Future research should aim to refine the design of these programs and assess the sustainability of the observed improvements.

Copper doped Zinc Oxide nanofilms were prepared using a simple and low cost wet chemical method. The microstructures, phase structure, Raman shift and optical absorption spectrum as well as magnetization were investigated for the nanofilms. Room temperature ferromagnetism has been observed for the nanofilms. Structural analyses indicated that the films possess wurtzite structure and there are no segregated clusters of impurity phase appreciating. The results show that the ferromagnetism in Copper doped Zinc Oxide nanofilms is driven either by a carrier or defect-mediated mechanism. The present work provides an evidence for the origin of ferromagnetism on Copper doped Zinc Oxide nanofilms.
