Purpose: This study was conducted to identify changes in limb circumferences among patients admitted to the intensive care unit (ICU) and related factors. Methods: We conducted a prospective observational study with 27 patients from 3 ICUs at a university hospital located in B city of Korea, from September 1 to October 30, 2015. The circumferences of the left and right upper arms, thighs, and lower legs were measured on the first, third, fifth, and seventh days of ICU admission. Information on the related factors was collected from the medical records. The data were analyzed using a linear mixed model method. Results: The limbs circumferences significantly reduced from day 3, and the changes continued till day 7. These changes were related to the gender of the subjects, restraints application, use of steroids, and continuous renal replacement therapy. Conclusions: Based on the above results, it can be concluded that ICU-acquired weakness begins before the third day of admission. Thus, early mobilization protocols for ICU patients need to be developed and implemented in order to improve long-term outcomes.

Cancer is a major health problem in the Arab region including Iraq. An adequate database is essential for effective cancer control strategies. Such a database may be provided through cancer registration but supportive household surveys may be useful. This article reports selected results on the feasibility of household surveys to support and validate cancer registration in Basrah governorate - southern Iraq. A large scale multi-stage cluster sample household survey was carried out in Basrah during 2013. It covered 6,999 households and involved gathering data on demographic characteristics and both incident cancer cases and cancer-related deaths among members of these households during a three-year recall period (2010-2012). The data obtained yielded an average annual incidence rate of 91 per 100,000 population (age-standardized incidence rate of 148.8 /100,000) and cancer specific mortality rate of 68 per 100,000 population (age-standardized mortality rate of 126.3/100,000). The results showed an overall pattern of cancer similar to that reported according to cancer registration but the household survey results were consistently higher than those of the cancer registration by a margin of approximately 20- 30% with respect to incident cancer and about 70 % with respect to cancer-specific mortality. Household surveys on cancer, while costly and time consuming, are a very useful additional source of information on cancer at the population level. They can be performed for specific purposes with effective resource mobilization.

Social media is being increasingly utilized in disaster relief work to identify safety issues, locate displaced-victims, and seek or provide support for those who need help. The presence of social media in disaster management has changed significantly in recent years, as it was not prevalent in the 2008 Wenchuan earthquake, but had become a powerful force in the 2013 Ya'an earthquake. This paper discusses the development of social media in disaster management via making a comparison between how it functioned in the two earthquakes. It examines the following aspects: who are the stakeholders that use social media in the earthquake management; how do they adopt this means in response to the earthquakes; and what are the outcomes of adopting social media with regards to public engagement and collaboration in an emergency event. As Sina Weibo acts as the equivalent of China's Twitter, the methodology relies on an analysis of posts in Weibo. The outcomes primarily show that: (1) authorities, celebrities and the public actively adopted social media for the purpose of information dissemination and resource mobilization; and (2) social media users are both content consumers and content generators in the times of earthquakes. The study concludes that social media as a backchannel communication tool is helpful for government institutions, corporations, and nonprofit organizations to build relationships with their stakeholders in the disaster management cycle. The result will interest academics and emergency management practitioners who are concerned with improving disaster communication.

This article assesses factors that affect the ability of local fire branch heads in Taiwan to mobilize volunteer organizations in local emergency responses. Data from a survey of local fire branch heads in Taiwan is analyzed by using an OLS model to test three hypotheses regarding the relationship between the dependent variable, perceived ability to mobilize volunteer organizations in emergency response, and three explanatory variables: organizational capacity, quality of communication, and the quality of citizen engagement ex-ante to emergency response. The model indicates a positive relationship between the ability to mobilize volunteer organizations in emergency response, the quality of communications, and the quality of citizen engagement in preparedness. The research suggests that local fire branch heads and volunteer organizations should begin the process of emergency response mobilization in the preparedness stage. The quality of the citizen engagement in preparedness stages should increase the ability of local fire branch managers to mobilize external resources in emergency response.

Purpose: This study is not a fragmentary study on characteristics of respiratory synergist when breathing, however it was intended to determine the effect of currently available respiratory exercise and to provide basic clinical information through investigation of oxygen demand and respiratory synergist that mobilizes for respiration during application of respiratory exercise. Methods: Experimental group I was selected from second grade of severity classification of GOLD, which has the highest percentage among patients with COPD, and experimental group II was selected from third grade of severity classification as a clinical sampling. After respiration pursing up lips and diaphragm respiration exercise were mediated together for six weeks, activity of respiratory muscles and oxygen saturation were measured and analyzed. Results: In comparison of change of respiratory synergist and oxygen saturation, activity of respiratory synergist in sternocleidomastoid muscle and scalene muscle showed a meaningful decrease in experimental group I. And, in comparison of change of respiratory synergist and oxygen saturation, activity of respiratory synergist in rectus abdominis muscle showed a meaningful increase in experimental group II. In comparison of change of respiratory synergist and oxygen saturation, activity of respiratory synergist in sternocleidomastoid muscle, scalene muscle, and rectus abdominis muscle showed a meaningful difference between experimental groups. Conclusion: Respiratory synergists work mainly as agonist of chest and upper limbs. Therefore it is very important to lower mobilization of respiratory synergist when breathing. It is considered that a multilateral approach and continued clinical research for improvement of respiratory function for patients with COPD will be needed in the future.

G-protein coupled receptors (GPCRs) constitute an important class of drug targets and are involved in every aspect of human physiology including sleep regulation, blood pressure, mood, food intake, perception of pain, control of cancer growth, and immune response. Radiometric assays have been the classic method used during the search for potential therapeutics acting at various GPCRs for most GPCR-based drug discovery research programs. An increasing number of diverse small molecules, together with novel GPCR targets identified from genomics efforts, necessitates the use of high-throughput assays with a good sensitivity and specificity. Currently, a wide array of high-throughput tools for research on GPCRs is available and can be used to study receptor-ligand interaction, receptor driven functional response, receptor-receptor interaction,and receptor internalization. Many of the assay technologies are based on luminescence or fluorescence and can be easily applied in cell based models to reduce gaps between in vitro and in vivo studies for drug discovery processes. Especially, cell based models for GPCR can be efficiently employed to deconvolute the integrated information concerning the ligand-receptor-function axis obtained from label-free detection technology. This review covers various platform technologies used for the research of GPCRs, concentrating on the principal, non-radiometric homogeneous assay technologies. As current technology is rapidly advancing, the combination of probe chemistry, optical instruments, and GPCR biology will provide us with many new technologies to apply in the future.

Weirs are conventional structures that control water level and velocity in streams to facilitate water resource management. Despite many weirs built in streams, there is little information how weirs change hydrology regime and how that translates to sediment and phosphorus (P) responses. This study evaluated the influence of weirs on P retention and mobilization in an urban tributary of the Han River in Korea. Total P concentrations in sediments upstream of weirs were higher than the downstream site, mainly due to the increase of potentially available fractions (labile P and aluminum- and iron-bound P) (p < 0.05). Equilibrium phosphorus concentrations ($EPC_o$) were lower than soluble reactive phosphorus (SRP) concentrations of stream waters, but there was an increasing trend of sediment $EPC_o$ upstream of weirs compared to the downstream site (p < 0.001) indicating a greater potential for P release upstream of weirs. Sediment core incubation showed that SRP release rates upstream of weirs were higher than the downstream site under anoxic conditions of the water column (p < 0.01), but not under oxic conditions. SRP release rates under anoxic conditions were greater than that measured under oxic conditions. Un-neutral pH and increased temperature could also enhance SRP release rates upstream of weirs. We conclude that weirs can increase P retention within stream sediments and potentially promote significant P releases into waters, which in turn cause eutrophication.

이 연구는 북한의 저널리즘 이론이 강조하는 국제정세선전과 당 대외정책간의 관계를 중심으로 북한신문의 국제뉴스가 지닌 보도형식과 내용, 그리고 정세선전의 특성을 고찰하였다. 이를 위해 북한의 대표적 일간지 ${\ulcorner}$로동신문${\lrcorner}$과 ${\ulcorner}$민주조선${\lrcorner}$의 국제정세선전 기사를 내용분석하였다. 분석결과에 따르면, 북한신문의 국제뉴스는 김정일 체제가 지향하는 최근의 대외정책 변화를 충실하게 반영하여 당 중앙이 의도하는 대로 국제관계를 분석하고 정세추이를 선전 선동함으로써 주민을 통제하고 동원하는 이데올로기 도구로 활용되고 있음을 알 수 있었다. 그러나 보도의 형식과 내용면에서 두 신문 간의 의미 있는 차이는 발견되지 않았다. 북한의 정치권력과 언론보도의 조응관계를 국제 커뮤니케이션의 관점에서 논의하였다.
