Conditions related to body composition and aging, such as osteopenic obesity, sarcopenia/ sarcopenic obesity, and the newly termed osteosarcopenic obesity(triad of bone, muscle and adipose tissue impairment), are beginning to gain recognition. Currently, it has begun to attract the attention of scholars from all over the world, however, for this disease, it still needs a more clear understanding and perception. Therefore, this article considered the osteoporosis, muscle depression, and obesity, these diseases as a gate to study the relationship among muscle, bone, and fat. In addition, in the aging process, the formation of IGF-cortisol, testosterone, and estrogen is sensitive. These hormones can not only absorb muscle protein metabolism, but also affect alienation. The decrease in IGF-cortisol in the elderly resulted in increased visceral fat, decreased muscle mass and bone mineral density, and then affected decreased skeletal muscle atrophy and decreased quality. The reduction of skeletal muscle quality and strength and increase body fat affected the adipose tissue to produce inflammatory cytokines, thereby reduced skeletal muscle, promoted cardiovascular disease, metabolic syndrome and insulin resistance in chronic diseases. Almost all chronic inflammatory diseases were associated with bone, muscle and fat. These mechanisms were complex and interrelated. Inflammation reduces bone formation, increases fat and reduces muscle mass. And thus not only had a significant impact on the motor system, but also made the incidence increase of fracture, osteoporosis, fragile syndrome, fall, osteomalacia and other bone disease. This article aimed to start from the interaction between the muscles and bones of the elderly, extended to obesity, muscle deficiency, osteoporosis and other diseases, finally, from a nutritional point of view, to discuss how to treat osteoporosis obesity.

Fracture toughness of five different reactor pressure vessel steels was characterized in the transition temperature region by the ASTM E1921-97 standard method using Charpy-sized small specimens. T he predominant fracture mode of the tested steels was transgranular cleavage in the test conditions. A statistical analysis based on the Weibull distribution was applied to the interpretation of the scattered fracture toughness data. The size-dependence of the measured fracture toughness values was also well predicted by means of the Weibull probabilistic analysis. The measured fracture toughness transition curves followed the temperature-dependence of the ASTM master curve within the expected scatter bands. Therefore, the fracture toughness characteristics in the transition region could be described by a single parameter, so-called the reference temperature (T。), for a given steel. The determined reference temperatures of the tested materials could not be correlated with the conventional index temperatures from Charpy impact tests.

There are many pilot programs and projects to implement the water quality trading (WQT) policy. But actual trading is relatively rare. The main reason of the scarce applications of WQT policy is the difficulty in determining the equalities between the trading sites. The uncertainty of the impacts of the nonpoint sources pollutant discharges between up and downstream urban development areas also makes the implementation of the policy harder. The simulated results from the watershed modeling program will be used to calculate the point and nonpoint sources pollutants of the future urban development scenarios. The amount of suspended sediments resulting from the urban developments and rainfall intensities will be used to indicate the environmental impacts of the water body between upstream and downstream. The water quality impacts after development scenarios to the outlet of the watershed were transferred to the trading units between two sites. The recommended trading units can be used as a decision support system for policy makers and stakeholders to carry out better WQT practices.

It is obvious that the sales of smart phones are increasing every year whereas the growth rate is decreasing year by year from 2010 through the investigation of the current situation of the smartphone market. Therefore, the GUI design of smartphones has gradually become the major design difference and selling point. In this research background, the purpose of this paper is to investigate and analyze the relationship between GUI design and user experience which takes the 20 generation smartphone users in China as the research objects, so as to understand the impact of GUI design on user experience. In this paper, five visual elements of GUI design are derived from prior study, and five essential factors of user experience are educed by using online review text analysis and KJ. Finally, this thesis makes a questionnaire survey on the 20 generation smartphone users in China, and analyzes the influence of GUI design on the user experience. Meanwhile, we put forward some suggestions for improving the user experience on the basis of the survey results.

We studied in order to find out suitable amounts of board by visual effects to establish indoor boards and human psychological effects by several board designs. Thirty students of C university were tested in constant temperature/humidity room and interviewed after tests. The experimental visual images were projected from 54' TV. As a result, the board length that showed high preference and satisfaction was the 90cm both horizontal and vertical direction. We found that vertical board gave an impression of a linear and narrow shape and the horizontal board gave wide space and cool feeling from psychological analytical study. The factors affecting satisfaction in horizontal direction were refreshing, intimacy, beauty, area, splendor and those in vertical direction were a sense of security, beauty, texture, intimacy, continuity, extensity, natural feeling. We got 5 factors from the result of factor analysis in order to get psychological factor axis. Those were pleasantness, artificiality, openness, dynamics, refinement. By multiple regression analysis, the factor pleasantness had the highest impact on visual satisfaction on scenary. The study on psychological factor difference by analysis of variance showed that psychologically feeling amount about pleasantness, artificiality, dynamics, refinement, and openness had statistically meaningful difference despite of board direction. We found that the 90cm had a tendency as a changing point leading image change by the investigative analysis of board direction based on factor points.

New molecular markers of cancer had emerged with novel applications in cancer prevention and therapeutics, including for breast cancer of unknown causes, which has a high impact on the health of women worldwide. The purpose of this research was to detemine protein and mRNA expression of synaptic vesicle 2 (SV2) isoforms A, B and C in breast cancer cell lines. Cultured cell lines MDA-MB-231, SKBR3, T47D were lysed and their protein and mRNA expression analyzed by real-time PCR and western blot technique, respectively. SV2A, B proteins were identified in non-tumor (MCF-10A) and tumor cell lines (MDA-MB-231 and T47D) while SV2C only was found in the T47D cell line. Furthermore, the genomic expression was consistent with protein expression for a such cell line, but in MDA-MB-231 there was no SV2B genomic expression, and the SV2C mRNA and protein were not found in the non tumoral cell line. These findings suggest a possible cellular transdifferentiation to neural character in breast cancer, of possible relevance to cancer development, and point to possible use of SV2 as molecular marker and a vehicle for cancer treatment with botulinum toxin.

Because effect of value elevation is great as it is fast that construction VE is enforcement, VE at the design phase is more and more important more than construction process phase. But, is exerting negative impact for construction process phase by various problem that happen at design phase, and is causing discord to between project partners. Therefore, quality security in design phase is important first of all. Hereupon, this study emphasized that need VE at the design phase of extension plan forward more and more because achieved process that derive conceptional estimation by quantitative value calculating value index (V) through provision of design function point (F) and LCC expense (C) by comparison method of construction and chooses optimum method of construction through VE/LCC analysis example in improvement of soft soil ground method choice process of design phase.

The aim of this study is to suggest design requirements on the military barriers which are installed to reduce critical damage on protective facilities against sudden pin-point attacks caused by North Korean artilleries. For this purpose, site investigation and review of design drawings associated with barriers built in the contact areas are conducted. With identified data concerning barriers, the geometric modeling, which is used in the structural analysis, is performed. And then, the possible threat of North Korea is determined based on intelligence preparation of battlefields. Once the structural modeling and threat analysis are completed, structural damage on barriers and protective facilities are assessed in terms of impact, penetration, scabbing, and blast pressure effects. According to the analysis results, the thickness of barriers should be 450mm at least and current established barriers need to be structurally reinforced via sectional enlargement.

Recently, the social issues such as low birth rate, an aging population has brought about decreasing labor productivity and productive population. To relieve these problems, the government has planned to set up smart working infrastructure and will raise the number of smart worker to around 30 percent of the total working population by 2015. This study scrutinizes to the meaning of smart working with the concepts of new work pattern and open innovation. The empirical analysis result shows 56.9% of SMBs thought a need for such system and 60.1% of them answered to adopt it. And the market related to smart working of SMBs will increase to 17.5% every year to the point that by 2014. It will be worth 1.54 trillion won and create up to 38,000 job positions. While prior researches on SMB suggested key drivers and guideline for innovation, this study gives some implications of impact and ripple effect of smart working as an innovation factor based on empirical analysis.
