Purpose: The aim of this study was to examine the differences in critical thinking and professionalism between Korean and Chinese nursing students. Critical thinking and professionalism were a part of five domains to evaluate nursing education: critical thinking, professionalism, leadership, communication, and nursing practice from the Korean Accreditation Board of Nursing. Methods: Data were collected from 207 college nursing students: 104 students from the 4-year degree program in Korea and 103 from the 5-year degree program in China from September 2006 to September 2007. The instruments for Chinese students were translated in Chinese and re-translated to check accuracy. The data were analyzed by using the SPSS/PC+ Win 12.0 Version. The $x^2$-test to compare general characteristics and the t-test to examine the differences of the study variables were conducted. Results: Korean nursing students reported significantly higher scores of critical thinking than did Chinese students while Chinese students reported significantly higher scores of professionalism. Students took previous courses associated with critical thinking reported significantly higher scores than did those without previous courses taken. There was no significant difference in scores of professionalism whether students had previous experience of related courses or not. Rather than, students with clinical practice reported higher scores of professionalism than did those without clinical practice. Conclusion: Levels of critical thinking were influenced by course focusing on critical thinking while professionalism was improved by combination of associated courses and clinical practice. For follow-up study, there is needed to examine nursing curriculum between Korea and China.

This paper begins with the thesis that the so-called 'Be Slow' Movement has not only affected the contemporary life style but also the current fashion trend in the West as well as in Korea. The influence of the 'Be Slow' Movement on the everyday life of Western and Korean society can be documented by recent books, news reports, and many articles from various kinds of mass media and fashion magazines since the year 2000. The results of this study can be summarized as follows. First. the 'Be Slow' Movement is a new cultural phenomenon and very different from that of the past century. It has emerged very recently and it could affect the life style o( its followers for a long period of time. Second, the influence of 'Be Slow' Movement on everyday life can be witnessed in many behavioral choices. such as the preference of organic food and natural cooking for food and the preference of rural life and a green patch of land for housing. Some aspects of the way of rearing the children and long-term planning of one's life are also under the influence of 'Be Slow' Movement. In a way. the life style Proposed by the 'Be Slow' Movement is somewhat similar to that of 'Bobos'. Third, the influence of 'Be Slow' Movement on the current fashion trend can be observed in the appreciation of time-consuming labour and increased usage of D.I.Y. clothing. The higher value of fashion goods with handcrafted part or scarce luxury item are good examples of the influence by the 'Be Slow' Movement. One can say that the 'Be Slow' Movement is not retrogression, but a re-creation of time and space to be grateful for one's life. Thus, it is not anti-technology but a commercialism with technology in order to enhance the quality of life and to place people in the center of production and consumption. Consequently, one may say that the 'Be Slow' Movement is a appropriate and affluent way of living.

Although the effects of adenosine on the heart, including the clinical suppression of cardiac arrhythmias, have been recognized for more than half a century, it is only in the last decade that the therapeutic potential of adenosine has been recognized. The objective of this study was to determine if augmentation of myocardial adenosine levels during global ischemia improves functional recovery after reperfusion. We used to modified Langendonf system to evaluate myocardial protective effect. Isolated rat hearts were subjected to 90 minutes of deep hypothermic arrest(15$^{\circ}C$) with modified St. Thomas'Hospital cardioplegic solution used to provide myocardial protection. Myocardial adenosine levels were augmented during ischemia by providing exogenous adenosine in the cardioplegic solution. Two groups of hearts w re studied: (1) control group(n=10) cardioplegia alone; (2) adenosine group(n=10) adenosine(0.75mg/kg/min) added to the cardioplegic solution. Significantly better percent recovery(p<0.01) in hemodynamics(except heart rate) at 60 minutes after reperfusion was evident compared to baseline values in the adenosine group. (systolic no란ic pressure : 78.5$\pm$3.6% vs 66.6$\pm$5.9%, airtic overflow volume : 61.7$\pm$ 11.6% vs 37.2$\pm$ 15.4%, coronary flow volume 77.1$\pm$7.5% vs 57.2$\pm$ 11.1%, and cardiac output : 65.6$\pm$ 11.5% vs 44.2$\pm$ 12.4%). Heart rate was similar in two groups(94.4$\pm$4.8% vs 95.3 $\pm$ 6.8%). Adenosine groups resulted in significantly rapid recovery time of heart beat after reperEusion(p<0.01) (24.5$\pm$7.6 sec. vs 179.0$\pm$ 131.1sec.). In biochemical study, CPK levels(0.1 $\pm$0.3U/L vs 1.4$\pm$0.8U/L) and lactic acid levels(0.08$\pm$0.Immol/L vs 0.34$\pm$0.2 mmol/L) were significantly low in adenosine groups(p<0.01). We concluded that adenosine included cardioplegia have better recovery effects after r perfusion in myocardial ischemia compared to adenosine free cardioplegia.

The purpose of this study was to investigate the anthropometric variables, dietary behaviors, nutrient intakes and distribution of serum lipid levels for Muan-gun inhabitants. The subjects was consisted of 212 men and 317 women. There were significant differences in the height, weight, BMI and fat mass with ages. In the onion intake status. 90.6(79.9)% of men(women) liked. 56.8(46.4)% of men(women) intakes 3 times per day, 29.6(40.8)% of men(women) 50g per one time and 83.1(87.5)% of men (women) after cooking. The mean energy intake of the subjects were 2,043㎉ for men and 2,105㎉ for women. Men (women) consumed 88(90)g protein. 34(38)g lipid, 340(355)g carbohydrate, 10.5(11.7)g fiber, 655(757)mg calcium. 1,396(1,421) mg phosphorous. 14.7(15.9)mg iron. 7.061(7,244)mg sodium, 3.597(3,704)mg potassium, 1.983(1,369)RE retinol, 1.4(1.5)mg thiamin. 1.1(1.4)mg riboflavin. 19.4(20.4)NE niacin. 172(160)mg ascorbic acid and 232(239) mg cholesterol. respectively. The level of triglyceride(TG) was 136.0(114.2)mg/dl, total cholesterol(TC) was 179.1(174.9)mg/dl HDL-C was 43.3(43.3)mg/dl, LDL-C was 109.6(107.9)mg/dl. VLDL-C was 26.8(22.8)mg/dl and AI was 3.2(3.0) And 68.1(79.0)% of men(women) were assessed as Normocholesteroiemia(NC) and 66.2(69.9)% of men(women) as Normotriglyceridemia (NTG). Most of the subjects in Muan-gun preferred and ate onions routinely and had normal range of serum cholesterol and triglyceride level. Therefore it is suggested that intake of onions is effective for decreasing the serum cholesterol and TG levels.

Purpose: This study is designed to analyse etiology and bone pattern at the first visit using cone-beam computed tomography (CBCT) and to evaluate the treatment outcome of conservative treatment in temporomandibular disorder (TMD) patients with rheumatoid arthritis (RA). Methods: One hundred condyles in 50 subjects with RA were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Dental Hospital, diagnosed as TMD. Condylar bone changes were classified by normal, erosive bony change, proliferative bony change and combined group (erosive bony change+proliferative bony change). They were treated conservatively with physical therapy, medication, behavioral therapy and/or occlusal stabilizing splint therapy. After 3 months on average, patients were re-evaluated with regards to subjective symptoms and the clinical findings were investigated. Results: TMD patients with RA have behavioral contributing factors such as parafunctional habit. The results that analyse bone pattern at the first visit using CBCT proliferative bony changes group (32.6%) were more common than erosive bony changes group (15.2%). In comparison between unilateral and bilateral bony change in temporomandibular joint, the ratio showed no significant differences. After 3 months of conservative treatments, pain, noise, limitation of motion (LOM) were markedly improved regardless of occlusal splint therapy. However only LOM was significantly improved through occlusal splint therapy during 3 months. Conclusions: TMD patients with RA had similar behavioral contributing factors and characteristics of CBCT images shown in general TMD patients and also similar response to conservative treatment so it is difficult to differentiate. Therefore when TMD patients show symptoms corresponding to clinical diagnostic criteria of RA at the first visit, serological testing should be conducted and through this, early diagnosis and treatment of RA should be initiated.

The strictly freshwater red algal order Batrachospermales has undergone numerous taxonomic rearrangements in the recent past to rectify the paraphyly of its largest genus Batrachospermum. These systematic investigations have led to the description of new genera and species as well as re-circumscription of some taxa. Specimens collected from two locations in the southeastern USA were initially identified as being allied to Batrachospermum sensu lato, but could not be assigned to any recognized species. Representative rbcL (plastid) and COI-5P (mitochondrion) sequences showed these specimens to be similar to each other and not closely matching the previously published sequence data for other Batrachospermum taxa. Comparison of sequence variation and morphology with a broader range of batrachospermalean taxa resulted in the proposal of a new monotypic genus Lympha mucosa gen. et sp. nov. to accommodate these specimens. Lympha mucosa is sister to members of a newly described genus Volatus, but the two genera are easily distinguished based on straight versus curved, twisted or spirally coiled carpogonial branch, respectively. This new taxon has morphological similarities to Batrachospermum sections Turfosa and Virescentia, but can be differentiated based on genetic divergence in rbcL and COI-5P as well as a combination of morphological characters: dense, compressed whorls, axial carposporophytes with a single type of gonimoblast filament; cortication of the main axis closely appressed; and short, straight carpogonial branch arising from the pericentral cell and carpogonia with unstalked, lanceolate trichogynes. This new taxon adds to the freshwater red algal diversity of the southeastern USA, a region already known for biodiversity and high endemism of the aquatic flora and fauna. It is also a relevant new addition to the taxonomic knowledge of the freshwater red algal Batrachospermales.

In this study, we evaluated the reusable leuco malachite green (LMG) micelle gel properties dependent on various components of chemical concentration and compared with leuco crystal violet (LCV). The gels were delivered to 10, 20, 30, 40 and 50 Gy at 6 MV photon beam from linear accelerator and analyzed using spectrophotometry. We confirmed that the reusable LMG and LVC absorbance wavelength peak were made up at 630 nm and 600 nm respectively. The transparency of reusable LMG decreased with higher amount of trichloroacetic acid (TCAA) and lower reusable LMG dyes. 1 mM reusable LMG was the lowest transparency. The sensitivity was increased depending on lower trichloroacetic acid (TCAA) concentrations and the amount of suitable surfactant (Triton X-100), which was found to be 7 mM. However, we were not able to investigate sensitivity effects factor from reusable LMG dyes. The gel dosimeter containing 16 mM TCAA, 7 mM Triton X-100 gel dosimeter showed the highest sensitivity at $0.0021{\pm}0.0001cm^{-1}.Gy^{-1}$. The sensitivity of LCV was found to be higher than reusable LMG at $0.0037{\pm}0.0005cm^{-1}.Gy^{-1}$. The reusable LMG and LCV dose responses were shown to be $R^2=0.997$, $R^2=0.999$ respectively, as stable measurement results. Future research is necessary to improve dose sensitivity, dose rate dependency and gel fading with extensive chemical formulations.

Adenylate kinase (AK) enzyme which acts as the catalyst of reversible high energy phosphorylation reaction between ATP and AMP which associate with energetic metabolism and nucleic acid synthesis and signal transmission. This enzyme has three distinct domains: Core, AMP binding domain (AMPbd) and Lid domain (LID). The primary role of AMPbd and LID is associated with conformational changes due to flexibility of two domains. Three dimensional structure of human AK1 has not been confirmed and various mutation experiments have been done to determine the active sites. In this study, AK1R138A which is changed arginine[138] of LID domain with alanine[138] was made and conducted with NMR experiments, backbone dynamics analysis and mo-lecular docking dynamic simulation to find the cause of structural change and substrate binding site. Synthetic human muscle type adenylate kinase 1 (hAK1) and its mutant (AK1R138A) were re-combinded with E. coli and expressed in M9 cell. Expressed proteins were purified and finally gained at 0.520 mM hAK1 and 0.252 mM AK1R138A. Multinuclear multidimensional NMR experiments including HNCA, HN(CO)CA, were conducted for amino acid sequence analysis and signal assignments of $^1H-^{15}N$ HSQC spectrum. Our chemical shift perturbation data is shown LID domain residues and around alanine[138] and per-turbation value(0.22ppm) of valine[179] is consid-ered as inter-communication effect with LID domain and the structural change between hAK1 and AK1R138A.

To investigate the genetic relationship among 12 species belonging to the Fusarium section Martiella, Dlaminia, Gibbosum, Arthrosporiella, Liseola and Elegans, the internal transcribed spacer(ITS) regions of ribosomal DNA (rDNA) were amplified with primer pITS1 and pITS4 using the polymerase chain reaction(PCR). After the amplified products were digested with 7 restriction enzymes, restriction fragment length polymorphism (RFLP) patterns were analyzed. The partial nucleotide sequences of the ITS region were determined and compared. Little variation was observed in the size of the amplified product having sizes of 550bp or 570bp. Based on the RFLP analysis, the 12 species studied were divided into 5 RFLP types. In particular, strains belonging to the section Martiella were separated into three RFLP types. Interestingly, the RFLP type of F. solani f. sp. piperis was identical with that of isolates belonging to the section Elegans. In the dendrogram derived from RFLP analysis of the ITS region, the Fusarium spp. examined were divided into two major groups. In general, section Martiella excluding F. solani f. sp. piperis showed relatively low similarity with the other section. The dendrogram based on the sequencing analysis of the ITS2 region also gave the same results as that of the RFLP analysis. As expected, 5.8S, a coding region, was highly conserved, whereas the ITS2 region was more variable and informative. The difference in the ITS2 region between the length of F. solani and its formae speciales excluding F. solani f. sp. piperis and that of other species was caused by the insertion/deletion of nucleotides in positions 143-148 and 179-192.

Acute spinal cord injury can produce neurologic injury with many physical, psychological and social ramifications. It has been shown that two separate components combine to produce neurologic damage in acute spinal cord injury : the primary and secondary injuries. The primary mediators of spinal cord injury include the actual mechanical tissue disruption which is a passive process that occurs immediately following the trauma. A secondary injury cascade follows which appears mediated by cellular and molecular processes working through complex mechanisms. Both the primary and secondary injury cascades produce cell death both in neuronal and supporting cell tissues. Recovery from central nervous system(CNS) disorders is hindered by the limited ability of the vertebrate CNS to regenerate injured cells, replace damaged myelin sheath, and re-establish functional neuronal connections. Of many CNS disorders including multiple sclerosis, stroke, and other trauma, spinal cord injury is one of the important diseases because of the direct association with the functional loss of the body. Previous studies suggest that substantial recovery of function might be achieved through regeneration of lost neuronal cells and remyelination of intact axon in spinal cord injury which is occurred frequently. As a therapeutic approach in spinal cord injury, recently, cell transplantation provides a potential solution for the treatment of spinal cord injury. This review describes the characteristics of spinal cord injury and presents some evidence supporting functional recovery after cell transplantation following spinal cord injury.
