Representative cDNA libraries were constructed from various tissue sources of Hemibarbus mylodon, an endangered freshwater fish species in Korea, for the mining of expressed sequence tags (ESTs). Randomized and non-normalized EST analysis was performed with 7 unidirectional cDNA libraries generated from brain, intestine, kidney, liver, muscle, ovary or testis. Of 3,383 ESTs in total, the number of singleton was 2,029, and 333 contigs containing 1,354 ESTs were assembled (percent of unigene = 70.0%). Abundantly expressed gene transcripts and broad clustering of putative gene function were tissue-specific in general, and the redundancy was also variable among those libraries. Over half of H. mylodon ESTs were matched with orthologues from other teleosts among which zebrafish gene sequences were the most frequent in those matches. This initial setting of EST libraries achieved in the present study would be a fundamental basis for the banking of gene resources from this endangered fish species.

The present study utilized a shuttle mechanism of wet chemical absorption using MEA. In addition, industrial by-products containing a large amount of inorganic alkali substances were utilized for wet carbonization process. Chemical pretreatment of industrial by-products extracted calcium ions. ICP result of calcium ion was obtained up to 17,900 ppm(17.9%) by acidic substance. And also, In this work, 94% of recovery rate was obtained using wet MEA absorption process from $CO_2$ flow at the ambient condition. Through the liquid carbonation process, a sludge was fixed with rate of 0.175 mg of $CO_2$ per mg of sludge. It was found from XRD results that the structure of final product was composed of a calcite structure which is general structure of $CaCO_3$.

This study attempts to capture the low level carbon dioxide from indoor spaces using a granular activated carbon (WSC-470) which was modified with primary monoethanolamine. Adsorption capacity of the prepared adsorbents was evaluated for pure $CO_2$ flow and 3000 ppm as a function of MEA concentration and solvents such as distilled water, ethanol and methanol. The AC based adsorbents then were characterized in terms of pore structure by BET and chemical functionalities by XPS. While high concentration of MEA reduced specific surface area, porosity and micro pores, nitrogen content which can enhance the surface basicity was increased. The maximum adsorption capacity decreased comparing to the initial AC pellets, whilst the potential of selective adsorption amount at low level $CO_2$ was increased at 45% (0.73 mmol/g).

The steel-concrete composite column (i.e., the SC composite column) supports large-gravity loads and simplifies the installation and removal of the work in pouring the concrete. The column takes advantage of the in-plant prefabrication of steel, the speed of erection of a steel structure, and the fire resistance of steel. This paper presents the results of a parametric study using heat transfer analysis and a P-M interaction curve, and compares these results with the experimental results to check the accuracy of the proposed parametric studies. The parametric studies, such as the study of the concrete ratio of an area and the fire protection thickness, provide information on the fire resistance of SC composite columns.

This work deals with the chemical characterization of glycine aqueous solution in $CO_2$ absorption. Three alkali elements were impregnated into the glycine in order to facilitate the formation of amino functionalities. The analysis by IR revealed the transformation of ammonium ions to the amino group. In addition, the NMR analysis showed that the substitution of metal cations to the chemical shift of hydrogen and carbon atoms in glycine; in order of lithium glycinate, sodium glycinate and potassium glycinate depending on the electro negativity. Meanwhile, the $CO_2$ absorption at room temperature was the highest in primary amine solution, but at the increasing temperature sodium glycinate could capture more $CO_2$ than that of the pure amine solution.

Purpose: In this study the effects of Self-Development program on self-esteem and communication in middle school students were examined. Method: Forty-three middle school students in D City participated in a survey, which was carried out from October to November, 2007. To test the effects of the Self-Development Program, the students were divided into two groups, an experimental group (23) and a control group (20). The research design used in this study was a nonequivalent control group pre-posttest quasi-experimental research design. The research tools included a self-esteem scale and a communication scale. Chi-square test, paired t-test, and t-test were used to analyze the data with the SPSS/WIN 12.0 program. Result: Significant differences were found in self-esteem scores between the experimental group and the control group. But there were no significant differences between the two groups on communication scores. Conclusion: The results suggest that the Self-Development program is a useful nursing intervention for improving the self-esteem of middle school students.

Frozen shoulder is known to be a self-limited disease, and it is associated with chronic pain and limitation of joint movement. Although its etiology is still unknown, frozen shoulder is associated with several diseases. The diagnosis is made based on the medical history, the clinical and radiological examinations and exclusion of other shoulder pathologies. The skeleton is one of the most common sites of metastasis in patients with lung cancer. It has been reported that the incidence of bone metastases in lung cancer patients is approximately 30-40%, and the median survival time of patients with such metastases is 6-7 months. We experienced a case of a 77-year-old female patient who complained of right shoulder pain and limited joint mobility, and these symptoms were due to metastatic lung cancer in the shoulder.

In this work, nano-sized M-ferrites (M=Co, Ni, Cu, Zn) for the decomposition of carbon dioxide were synthesized by the chemical co-precipitation. From the thermogravimetric analysis, it was clear that the maximum weight loss of each sample took place below $350^{\circ}C$. High temperature calcination resulted in more systematic crystallines, smaller specific surface area and larger particle size. An analysis by FTIR in the range of $375{\sim}406cm^{-1}$ revealed the presence of chelates at the octahedral site, which implies the formation of spinel structure in the ferrites. The current work showed that a $500^{\circ}C$ is the optimum heat treatment temperature of metal ferrites for $CO_2$ decomposition reaction.

The present study attempted to impregnate alkali metals to amino acid in order to improve $CO_2$ absorption capacity. A used amino acid was glycine, of which pH increased up to about 11 with the addition of alkalies. $CO_2$ absorption capacity of amino acid salts was evaluated in a batch and a continuous process. The absorption capacity appeared in turns as; Sodium Glycinate ${\geq}$ Lithium Glycinate > Potassium Glycinate. Amino acid salts showed lower absolute capacity of $CO_2$ absorption than primary amine (Monoethanolamine) at $20^{\circ}C$. In a continuous absorption with 10% $CO_2$ flow, the increasing the reaction temperature, the increasing rate of absorption for amino and was higher that of than amino absorbent.

Background: Complex regional pain syndrome (CRPS) is a painful and disabling disease, yet the diagnosis of this can be difficult to confirm by purely objective measures. Therefore, we performed three-phasic bone scans and thermography as a work up in order to determine their predictive value and usefulness for making the diagnosis of CRPS. Methods: 44 patients who had been diagnosed with CRPS type-1, according to the modified criteria, were evaluated. All the patients were examined by performing a three-phasic bone scan and thermography as part of a work-up for diagnostic confirmation. The diffuse increased tracer uptake in the delayed image (phase III) was estimated by the positive findings. The findings were considered positive for CRPS if the thermographic findings showed temperature asymmetries between the affected and non- affected extremities of more than $1.00^{\circ}C$ Results: A review of the three-phasic bone scan for 44 patients indicated that 16 patients (36.4%) had diffusely positive scans, and thermographic abnormalities were noted in 35 of 44 patients (79.5%). Conclusions: The use of thermography in clinical settings can play an important role in the diagnosis of CRPS. However, a three-phasic bone scan alone cannot provide a completely accurate diagnosis, so it is imperative that the three-phasic bone scan data be integrated with the clinical evaluation and the other relevant tests.
