Purpose: The purpose of this study was to determine reliability and validity of the Postural Assessment Scale for Stroke Patients (PASS) in chronic stroke patients. Methods: A total of 43 stroke patients, who had a stroke more than 6 months previously, participated in the study. Reliability was determined by the intra-class correlation coefficient (ICC$_{3,1}$), Bland and Altman method and Cronbach's alpha by internal consistency. Validity was examined by correlation the PASS scores to the Berg Balance Scale (BBS), Trunk Control Test (TCT), and Fugl-Meyer Balance (FM-B) score. Results: The intra-rater reliability and the Absolute reliability of the PASS was good ICC$_{3,1}$=0.97 (95%CI 0.95$\sim$0.99) and excellent SEM=1.01 respectively. Cronbach's alpha value for PASS was found to be 0.94. There were significant correlations between the PASS and BBS, TCT, FM-B (r=0.65－0.96, p<0.01). Conclusion: The PASS provide reliable and valid instrument of the postural control assessment for chronic stroke patients.

Noise regulation of heavy construction machinery is getting stricter： 3 dB per every 4 year in European community. To meet this requirement many engineers have adopted the enclosing structures with thick absorbing materials and small opening, This increases internal temperature of the enclosure which have engine systems such as electric equipment that are vulnerable to heat, and engine block and muffler that can be regarded as heat sources. So noise control engineers have to consider a coupling problem: combining heat balance and noise reduction. This paper describes this approach by introducing simple heat transfer theory and SEA. The enclosing system of the loader whose enclosing structure consists of two rooms is investigated to show the validity of this method. The results represent that the simple heat transfer theory can be useful to estimate cooling performance when it is linked together by the back pressure theory in duct system. and the radiated noise can also be estimated by the SEA. Therefore a designer can use these approaches to define the opening ratio of an enclosure and the mass flow rate of air considering radiating noise.

The transition of turbulent kinetic energy(TKE) balance along the centerline of the flow unit, which is composed of straight-duct, contraction and free-jet, has been investigated by the hot-wire anemometry. It is found that the mean turbulent kinetic energy is balanced by the dissipation in the internal flow region ; by the production and the dissipation, through contraction ; and by the dissipation, in initial region(X〈8D) of free-jet. But in the developing region (8D〈X〈20D) it is balanced by all of the three(ie, diffusion, production and dissipation). Finally, in the downstream of free-jet, the mean TKE is balanced again by dissipation like as the beginning. The decay-laws along the centerline are checked in the region of free jet as well as in the straightduct. After the developing region of free-jet also exist the decay-laws, the exponent of the axial turbulence being bigger than of the radial.

The paper examines the determinants of employee engagement in the not-for-profit organization (NFPO) sector. A structured questionnaire survey of 205 NFPO employees in Vietnam was employed, preceded by in-depth interviews with NFPO associates and managers. After a multiple regression analysis to study the impact of five independent variables on one dependent variable, the study reveals that Work design and Work-life balance are positively and significantly associated with employee engagement. Of which, Work design is measured by the level of job fit, job autonomy, job challenge, and job meaningfulness. On the other hand, Work-life balance involves measurement aspects consisting of how reasonable the workload is and organizational support. Meanwhile, different from the business world, Leadership, Learning and Development, and Recognition do not show statistically positive impacts on employee engagement in NFPOs. Still, they are crucial back-supporting factors to ensure employee experience at work. Further, the study finds that personal growth contributes a great part to keep employees in the sector motivated. This paper brings the area of study to the forefront in an effort to benefit the practice of human resources management in NFPOs as well as support employees in the sector with a higher quality working experience.

On the basis of the paper described herein, rotor blade failure in the compressor, gas generator turbine, and power turbine and the resulting internal damage is contained within the peripheral hardware and engine casings. For the safety reason, the blade containment was regulated by aviation authority. For reducing the weight of the case, a heaviest single component of a jet engine, the blade containment capability was analyzed by engine manufacturer. The procedure established for containment design involves an energy balance method based on the comparison of the kinetic energy of released blade and the strain energy of the containment zone. The LS-DYNA simulation can also be introduced to predict behavior of released blade and case. All of the analytic and numerical result are described ${\ldots}$.

Purpose: This study analyzes the relationship between work-life conflict and turnover intention among hospital nurses. Furthermore, it seeks to determine whether the relationship between the two varies depending on the shift work condition of the nurses. Methods: A total of 435 nurses working at five tertiary hospitals were included in the study. The questionnaire included items on turnover intentions, work-life conflicts, sociodemographic factors, working conditions, and internal and external resources. Results: The level of work-life conflict among shift work nurses was higher than that of non-shift work nurses. The turnover intention was also higher for shift work nurses than for non-shift work nurses. Results from the multivariate logistic regression analysis revealed that the work-life conflict of nurses had a positive relationship with turnover intention. The effect of work-life conflict on turnover intention was greater for shift work nurses than for non-shift work nurses. Conclusion: Work-life conflict had a greater impact on the turnover intention of hospital nurses working under shift work conditions. Based on this study's findings, it can be suggested that, in order to reduce high turnover intention, it will be necessary to make specific efforts to balance work-life conflict and improve working conditions.

This study suggests that Korea - Russia economic cooperation, which has been sluggish in the meantime, should be revitalized as a small, medium sized business that can be practiced at the local level of both countries. Some large scales of national projects were difficult to realize due to some internal and external factors. Therefore, if Russia's Far East region of the complementary economic structure with the Korea's Gyeonggi Province of Korea could form the basis of cooperation by centering on SMEs, it further can be positive for promoting cooperation among South Korea, North Korea and Russia. The trilateral cooperation among two Koreas and Russia is necessary for the balance of political and economic powers in the East Asia. China's retaliation case regarding THAAD (Terminal High Altitude Area Defense) clearly showed that the greater the economic dependence on a particular country, the more threatening it could be. Therefore, it is important for the political and economic security to keep the balance by diversifying economic cooperation counterparts. As China's influence in the global economy grows, building value chains for mutual prosperity with various neighboring countries is gaining great importance. To this end, this paper examined Russia's Eurasian Strategy, New East Policy, and Far East Development Policy which were designed to seek the way to establish Russia's independent economic zone not absorbed by Europe and China.

The aim of this study is to compare measurements of abdominal muscle thickness using ultrasonography imaging (USI) to those using a special transducer head device, during five different trunk stabilization exercises, ultimately to determine which exercise led to the greatest muscle thickness. Thirty eight healthy subjects participated in this cross-sectional study. The five types of trunk stabilization - i.e., a sit-up on the supine, an upper and lower extremity raise with quadruped on the prone, a leg raise in sitting on the ball, trunk rolling on the ball, and balance using sling on the prone position - were each performed with an abdominal draw. The thickness of the abdominal muscle - including the transverse abdominal (TrA), internal oblique (IO), and external oblique (EO) - was measured by USI with a special transducer head device, at rest and then at contraction in each position. Data were analyzed using one-way repeated ANOVA with the level of significance set at ${\alpha}$=.05. The results were as follows: 1) the TrA thickness was statistically significant (p<.05), whereas the IO and EO thicknesses were not (p>.05); 2) among the five types of trunk stabilization, TrA thickness significantly increased with the balance using a sling in the prone position, (p<.05), whereas no significant difference was noted for the four types of trunk stabilization (p>.05); 3) reliability data showed that there was a high degree of consistency among the measurements taken using the special transducer head device (ICC=.92). In conclusion, the balance using a sling in the prone position was more effective than any of the four other types of trunk stabilization in increasing TrA thickness in healthy subjects.

Humane entrepreneurship is defined as "the pursuit of entrepreneurial growth and humane development for opportunity realization and sustainable organization." In this study, we evaluate and compare 19 countries by the degree to which 'humane entrepreneurship' is realized or emphasized. This study compares two factors of humane entrepreneurship, enterprise cycle and humane cycle, between different countries and examines a balance between the two. To make country-by-country comparison along humane entrepreneurship, we adopted Sethia and von Glinow's (1985) organizational culture model, which originated from Blake and Mouton's (1964) managerial grid model. Here, enterprise cycle and humane cycle of humane entrepreneurship correspond to concern for performance and concern for people. We suggest that keeping balance between humane cycle and enterprise cycle is important, because humane entrepreneurship is an internal condition for firm growth.

Objectives : This study is performed to understand the interrelation between 'Foot soyang muscle of the Gall bladder channel' and 'muscular system' on the basis of the link between meridian muscle theory and myofascial pain syndrome. Methods : We have researched some of oriental medical books about meridian muscle theory and western medical books about anatomical muscular system. Results & Conclusion : 1. Myofascial pain syndrome is the medical treatment which finds the start point of the pain in fascia and then treats it on the basis of object and concrete anatomical theory, so its application is needed for objectification of the oriental medicine. 2. There is a wide difference between myofascial pain syndrome and meridian muscle theory in that the former explains each muscle individually, while the latter classifies muscles systematically in the view of organism. 3. Foot soyang muscle contains Dorsal interosseous m, Extensor digitorum longus m, Musculus peroneus brevis, longus and, tertius, lliotibial tract, Vastus lateralis m, Gluteus m, Aximus m, Piriformis m, Tensor fasciae latae m, Gluteus minimus m, Obliquus internus & externus abdominis m, External & Internal intercostal m, Serratus anterior m, Pectoralis major m, Sternocleidomastoid m, Auricularis posterior m, Temporalis m, Masseter m, Orbicularis oculi m etc. on the basis of function and the nature of a disease reflected in muscle. 4. Foot soyang muscle keeps the balance of left md right of the body on the outside, while the Gall bladder keeps the balance of the JangBuKiHyeul(臟腑氣血) on the inside.
