In the event of the emergency patient care, cabin crew must take the charge of the first responder quickly. The basic emergency treatment knowledge of the cabin crew consisted of 80.5%~97.8% when the emergency scene showed up in the passenger and the types of emergency care with that the cabin crew could cope were bleeding control, fever, seizures, myocardial infarction, airway management, and partial airway obstruction management. Considering these cares, the improper emergency types revealed approximately 3.2%~20.0%. In airway obstruction there was followed by loss of consciousness and this led to cardiac arrest. In case of cardiac arrest, the cabin crew must know how to check breathing and to use the automated external defibrillator(AED). The life-threatening cardiac arrest can happen to any passenger in any time, so the cabin crew should meet with the emergency accident and apply the AED to the cardiac arrest victim.
In this paper We describe an algorithm which is devised for 4he partition o# the input space and the generation of fuzzy rules by the fuzzy entropy and tested with the time series prediction problem using Mackey-Glass chaotic time series. This method divides the input space into several fuzzy regions and assigns a degree of each of the generated rules for the partitioned subspaces from the given data using the Shannon function and fuzzy entropy function generating the optimal knowledge base without the irrelevant rules. In this scheme the basic idea of the fuzzy neural network is to realize the fuzzy rules base and the process of reasoning by neural network and to make the corresponding parameters of the fuzzy control rules be adapted by the steepest descent algorithm. The Proposed algorithm has been naturally derived by means of the synergistic combination of the approximative approach and the descriptive approach. Each output of the rule's consequences has expressed with its connection weights in order to minimize the system parameters and reduce its complexities.

Up to this date, numerous methods of analysis of electroplating solutions are published. Some, however, need lots of works before reaching final results, or require high technique and special instruments, and also some are unaccurate due to unclearnes of end point. Like our undevelope countries, technicians of electoplating shops are most high school gradutes or under, and have not much knowledge on chemistry. Furthermore, those technicians have to control their plating solutions by themselves without having enough analytical laboratory equiIJment. Therefore, in this paper the simplest, besides accurate method is investigated after comparing nu.merous methods published. Among the methods of 'copper determinations from acid and alkaline copper plating baths, EDT A titration method are chosen, due to these methods are the simplest and fastest for the evaluation of metal content, without requiring any special instrument. For acid copper solutions, chelate titrations were accurate enough. Since the end point of titration of chelate method is variable according to the kind of .indicators androther metal's coexsistence as well as solution comIJonent, many difficulties were encountered from cyanide' copper, on the contrary of acid copper bath. PAN, PV, and MX indicators were tried, but it is found that MX is the best. In cyanide solution, due to cyanide is the masking reagent, elimination of this component is essential, and finally found that elimination eN- by precipitation with AgN03 solution was the simplest and the most accurate way among others. This method was very accurate for the new plating solutions even coexistence with organic brightners. However used solutions for long months running have to be predetermined the accurate copper value by thiosulfate method from time to time, before chelate titration by means of AgN03 precipitation. Always some constant deviatioJ;ls will be seen according to the solutions nature. Therefore those deviation values have to be compensated each time.
Space is a phenomenon which is formed in the connection between environment and human beings and public space is built by a complex phenomenon of space. Each and every individual is connected to an environment and these individuals are connected to one another. A public commemorative space means souvenir and memorial which is designed for special purpose of remembrance of a specific area. One of the purposes of public commemorative space is memorial and that is the reason of doing public relation and educating citizens over the transom. However, the meaning and value of commemorative subject cannot be delivered or stuffed one-sidely. The target who receives messages from public commemorative space has reinterpreted the messages of his own with his personal experience, knowledge and sensitivity. It results in an unexpected phenomenon of public commemorative space. Therefore, public commemorative space should be considered in a mutual communication structure rather than a purpose of memorial itself. Korean public commemorative space is focused on public relation and education for memorial. In other words, Korean public commemorative space is neglected its important possibility of the productive chapter of mutual communication. The mutual communication structure of public commemorative space which is based on variety and haecceity is ripped up by the message over the transom. It destroys the self-control and creativity of public commemorative space, and derives a negative result. By studying the function and meaning of public commemorative space, we should make the best use of it.
The present study considers a multi-span continuous bridge, isolated by lead rubber bearing (LRB). Dynamic soilstructure interaction (SSI) is modelled with the help of a simplified, sway-rocking model for different types of soil. It is well understood from the literature that SSI influences the structural responses and the isolator performance. However, the abovementioned effect of SSI also depends on the earthquake ground motion properties. It is very important to understand how the interaction between soil and structure varies with the earthquake ground motion characteristics but, as far as the knowledge of the authors go, no study has been carried out to investigate this effect. Therefore, the objectives of the present study are to investigate the influence of earthquake ground motion characteristics on: (a) the responses of a multi span bridge (isolated and non-isolated), (b) the performance of the isolator and, most importantly, (c) the soil-structure interaction. Statistical analyses are conducted by considering 14 earthquakes which are selected in such a way that they can be categorized into three frequency content groups according to their peak ground acceleration to peak ground velocity (PGA/PGV) ratio. Lumped mass model of the bridge is developed and time history analyses are carried out by solving the governing equations of motion in the state space form. The performance of the isolator is studied by comparing the responses of the bridge with those of the corresponding uncontrolled bridge (i.e., non-isolated bridge). On studying the effect of earthquake motions, it is observed that the earthquake ground motion characteristics affect the interaction between soil and structure in such a way that the responses decrease with increase in frequency content of the earthquake for all the types of soil considered. The reverse phenomenon is observed in case of the isolator performance where the control efficiencies increase with frequency content of earthquake.
Various minor discomforts are reported to be complained by the pregnant women. but what were and how much were they complained has not been revealed until recently. So, These lack of knowledge have given nurses difficulties in planning of care to promote the health during the pregnancy. Objectives of this study were to identify the rate of complaints in each minor discomforts and to explore the influencing factor on reduction of complaints of minor discomforts. The subjects were 120 mothers, who delivered their babies in hospital, from September to December 1990 and the reason why the postpartum mothers were selected as the subjects were minor discomforts could develope during the entire period of pregnancy. Data were gathered by the questionnares and analized statistically using SAS and SPSS program. Results were as follows. 1. More than one third of the subjects complained frequent urination, fatigue, increase of the vaginal discharge, morning sickness, the increased urination at night, pain in leg, backache, edema in leg, constipation, dyspnea, varicose vein, flatulence, headache. 2. Minor discomforts complained to be severe in more than one third of the subjects were frequent urination and increased urination at night. 3. The influencing factor to reduce the complaints of minor discomfort was revealed to be the perceived family support (r=0.030431, t=0.0007). We suggest that nurses should emphasize the importance of the family support to the pregnant women and their family, and to explore the relationships among the locus of control, the perceived family support and the complaints of minor discomforts.

Recent findings from The Cancer Genome Atlas project have provided a comprehensive map of genomic alterations that occur in hepatocellular carcinoma (HCC), including unexpected mutations in apolipoprotein B (APOB). We aimed to determine the clinical significance of this non-oncogenetic mutation in HCC. An Apob gene signature was derived from genes that differed between control mice and mice treated with siRNA specific for Apob (1.5-fold difference; P < 0.005). Human gene expression data were collected from four independent HCC cohorts (n = 941). A prediction model was constructed using Bayesian compound covariate prediction, and the robustness of the APOB gene signature was validated in HCC cohorts. The correlation of the APOB signature with previously validated gene signatures was performed, and network analysis was conducted using ingenuity pathway analysis. APOB inactivation was associated with poor prognosis when the APOB gene signature was applied in all human HCC cohorts. Poor prognosis with APOB inactivation was consistently observed through cross-validation with previously reported gene signatures (NCIP A, HS, high-recurrence SNUR, and high RS subtypes). Knowledge-based gene network analysis using genes that differed between low-APOB and high-APOB groups in all four cohorts revealed that low-APOB activity was associated with upregulation of oncogenic and metastatic regulators, such as HGF, MTIF, ERBB2, FOXM1, and CD44, and inhibition of tumor suppressors, such as TP53 and PTEN. In conclusion, APOB inactivation is associated with poor outcome in patients with HCC, and APOB may play a role in regulating multiple genes involved in HCC development.
Construction development and greenhouse gas emissions have globally required a strategic management to take some steps to stain and maintain the environment. Nowadays, recycled aggregates, in particular ceramic waste, have been widely used in concrete structures due to the economic and environmentally friendly solution, requiring the knowledge of recycled concrete. Also, one of the materials used as a substitute for concrete cement is wollastonite mineral to decrease carbon dioxide (CO2) from the cement production process by reducing the concrete consumption in concrete. The purpose of this study is to investigate the effect of wollastonite on the mechanical properties and durability of conventional composite concrete, containing recycled aggregates such as compressive strength, tensile strength (Brazilian test), and durability to acidic environment. On the other hand, in order to determine the strength and durability of the concrete, 5 mixing designs including different wollastonite values and recovered aggregates including constant values have been compared to the water - cement ratio (w/c) constant in all designs. The experimental results have shown that design 5 (containing 40% wollastonite) shows only 6.1% decrease in compressive strength and 4.9% decrease in tensile strength compared to the control plane. Consequently, the use of wollastonite powder to the manufacturing of conventional structural concrete containing recycled ceramic aggregates, in addition to improving some of the properties of concrete are environmentally friendly solutions, providing natural recycling of materials.
AIS is one of the most critical systems in any organization. Data quality plays a critical role in a knowledge-based economy. The objective of this study is to identify the most important factors for accounting information quality and their impact on AIS data quality outcomes. This study includes an extensive literature review to identify a set of CSF for data quality. The study uses empirical data to test the research hypothesis and resluts show that the top three most important factors that affect AIS's data quality are toop management commitmentm the nature of the AIS and input controls. The study further uses regression analysis to test the effect of those factors on AIS data quality, finding that there is a significant positive relationship between the perceived performance of the three factors and AIS data quality putcomes. To be develop to AIS data quality further study for CSF's control methodology is necessary.
Objectives: Cold hypersensitivity has been regarded to be associated with digestive function. This study is aims to evaluate the correlation between digestive function and coldness of hands. Methods: We made a research of 80 women who is in ${\bigcirc}{\bigcirc}$ University. The patients were subjected to thermometer, and those with thermal difference between upper arm and palm were diagnosed with cold hypersensitivity. The patients were divided into two group by cold hypersensitivity group (n=20), and non-cold hypersensitivity group (n=19), and 39 women are mesured by Nepean dyspepsia index-Korean version (NDI-K) to evaluate the severity of functional dyspepsia. Results: There was no difference between two groups on age, height, weight. In functional dyspepsia symptom score, 6 symptoms (Pain in upper abdomen, Burning in upper abdomen, Cramps in upper abdomen, Pressure in upper abdomen, Vomiting, Bad breath) out of 15 were significantly increased in cold hypersensitivity group compared with non-cold hypersensitivity group. And in quality of life score, 3 domains (Tension/sleep, Interference with daily activities, Knowledge/control) out of 5, and total quality of life score were significantly decreased in cold hypersensitivity group compared with non-cold hypersensitivity group. Conclusions: This study shows the correlation between cold hypersensitivity and digestive function.
