In this article we consider the modern trends of global warming, GHG pollutions and discussions of the obligations of developed and developing countries before the UN Global Climate Summit in Paris. The article considers decarbonization as a national strategy, including complex tools for the improvement of energy efficiency, reduction of CO₂ and development of emissions trading systems. The author underlines that the Central Asian countries such as Kazakhstan and Turkmenistan, have the largest GHG potential in the region, and for this reason they should be within the framework of the UNFCCC and join the international process on development of the national decarbonization strategies.Thesemeasuresallowthese countries to join the global carbon trade marketing, international financial recourses, and significantly reduce CO₂ pollutions in the region.

The construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

Librarians, who work for University libraries in Korea experience a lot of confusion and difficulties because of rapidly-changing technological conditions and under-developed understanding of the University Libraries' full potential on the part of the users. I present the concept of 'Subject Services' as an approach which librarians could use to overcome these difficulties in their own way. The 'Subject Services' refers to the 'subjectized' collection development and reference services, which can more specifically address the users' needs. To make this idea more concrete, I selected Pusan National University Library as the case of my qualitative research. And I made use of various research techniques such as 'participant observation' and 'ethnographic interview'. After looking into the case library in depth, I found that the concept of 'Subject Specialist'. a person who has double master's degrees including that of library and information science, is more suitable to the University Libraries in Korea at the present developmental stage. At the end of this article, propose that the development of Core Collections, the improvement of subject-oriented reference services and the continuing education of librarians should be emphasized.

Suppose the kernel function $\kappa$ belongs to $S(R^2)$ and is symmetric such that $ < \otimes x, \kappa >\geq 0$ for all $x \in S'(R)$. Let A be the class of functions f such that the function f is measurable on $S'(R)$ with $\int_{S'(R)}$\mid$f((I + tK)^{\frac{1}{2}}x$\mid$^2d\mu(x) < M$ for some $M > 0$ and for all t > 0, where K is the integral operator with kernel function $\kappa$. We show that the \lambda$-potential $G_Kf$ of f is a weak solution of $(\lambda I - \frac{1}{2} \tilde{\Xi}_{0,2}(\kappa))_u = f$.

Ultra-fine fibers are spun by expensive fiber spinning technology using special spinnerets. Ultra-fine fibrous materials have attracted considerable attentions because of their potential applications as high performance wiping cloths, water absorbent sound proofing materials and moisture transfer sporting good. However, production expense of ultra-fine fibers is 5 to 7 times higher than general textile materials. The objective of this research is to develop cost-effective recycling process to produce multi-functional ultra-fine fibrous material in terms of the development of garnetting and carding machines for ultra-fine fibrous material waste and scrap. The efficiency of sound absorption for the recycled polyester nonwoven increased with decreasing length and thickness of component fibers, which was attributed to the reduction of air permeability. It is expected that high value and cost-effective textile products are developed using ultra-fine fibrous wastes and that sound proofing material and oil absorbent f

Background: This study used Surveillance, Epidemiology and End Results (SEER) pancreatic cancer data to identify predictive models and potential socio-economic disparities in pancreatic cancer outcome. Materials and Methods: For risk modeling, Kaplan Meier method was used for cause specific survival analysis. The Kolmogorov-Smirnov's test was used to compare survival curves. The Cox proportional hazard method was applied for multivariate analysis. The area under the ROC curve was computed for predictors of absolute risk of death, optimized to improve efficiency. Results: This study included 58,747 patients. The mean follow up time (S.D.) was 7.6 (10.6) months. SEER stage and grade were strongly predictive univariates. Sex, race, and three socio-economic factors (county level family income, rural-urban residence status, and county level education attainment) were independent multivariate predictors. Racial and socio-economic factors were associated with about 2% difference in absolute cause specific survival. Conclusions: This study s found significant effects of socio-economic factors on pancreas cancer outcome. These data may generate hypotheses for trials to eliminate these outcome disparities.

This study compared mother-toddler physical interaction by play type (traditional play, free play, block play), and child's sex and age. Subjects were 10 boys and 10 girls ranging in age from 25- to 36-months and their mothers. An observer videotaped the children and their mothers at play in their homes. Results showed that (1) mothers' physical interaction was not distinguished by play type or by child's sex or age. (2) Mothers expressed more positive emotion in traditional than in block play. (3) Younger children's play interactions were more nonverbal. (4) Children expressed more positive emotions in traditional play. This study provides groundwork for mother-toddler traditional play programs with potential for improving positive expression of emotion and attachment.

Altruistic virtuous caring, possibly originated from religion and/or spirituality, is indispensable for holistic health through channeling vital energy with diet, exercise and meditation. This is a participant-observed medical anthropological research of a first generation Korean elderly immigrant health professional woman living in a four generational family. She had hypertension and was concerned about possible attack of stroke. Multi-religious, spiritual, and cosmological vital energy based on holistic Nature-oriented health beliefs and practices influenced by psychosocial, cultural and economic background, education, self- discipline and self-cultivation of individual, and group or family may create health. Self-care beliefs based on confidence in self-control of one's life style for oneself and others influence individual and group health practice. The holistic alternative health beliefs and practices were proved to be efficacious and beneficial by her self-evaluation, evaluation of significant others, biomedical professionals, and laboratory tests. That may have potential application for global health.

This study was to examine the level of cognition, emotion, and social context of young children's injury risk behavior according to age and gender. The participants were 150 children of 3 to 5 years old(boys were 75 and girls were 75). The data were analyzed using descriptive statistics and two-way ANOVA. The results were as follows; 1) 5 year old children knew potential injury risk better than 3 or 4 year old children. 2) Boys felt less afraid than girls on risk situation. 3) As age increased, the score of social context was higher. The score of social context of boys was higher than that of girls.

Pitch is an attractive raw material for carbon fiber precursors due to its low cost stemming from its availability as a residue of coking and petroleum processes. Ford Motor Company reported a carbon fiber target price of $11.0/kg by using a fast cycle-time manufacturing method with carbon fiber in an inexpensive format, allowing for an average retail price of gasoline of $3.58/gallon. They also recommended the use of carbon fiber with strength of 1700 MPa, modulus of 170 GPa, and 1.5% elongation. This study introduced a ca. $5.5{\mu}m$ carbon fiber with 2000 MPa tensile strength obtained from a precursor through simple distillation of petroleum residue. Petroleum pitch based carbon nanofibers prepared via electrospinning were characterized and potential applications were introduced on the basis of their large specific surface area and relatively high electrical conductivity.
