To diagnose acute myocardial infarction(MI), many cardiac markers have been used in hematologic and biochemical analysis, and many studies have been published for hema-tologic and biochemical analysis associated with human acute MI. However, after occurrence of acute MI, the serial investigation for values in hematologic and bioche-mical analysis including chronic MI has rarely been performed. To observe the change of the serial values in hematologic and biochemical analysis, we induced artificial MI. The left main descending artery(LMDA) of the left coronary artery was ligated during the progression(day 1, 3, 5, 7, 14 and 30) of MI. Total 66 Sprague-Dawley rats were divided into the sham group(n=24, thoracotomy without LMDA ligation) and the experimental(MI) group(n=42, with LMDA ligation). And all individual in each group was sacrified at day 1, 3, 5, 7, 14 and 30 for the hematologic and biochemical analysis. In comparison of hematologic analysis between the sham and MI groups, the mean values of red blood cell(RBCs), hemoglobin and hematocrit(HCT) showed a steady increase. In biochemical analysis, the mean values of glucose, choles-terol, total creatine kinase(CK) and isoenzyme MB, and lactate dehydrogenase(LDH) were increased in all MI groups compared with the sham groups. The results of this study suggest that early hematologic and biochemical mean values occurred after acute MI are similar to those of human acute MI. In conclusion, we could observe the alterations and serial values in hematologic and biochemical analysis to the extent of chronic status after acute MI.

High-quality meat is of great economic importance to the pig industry. The 1-acylglycerol-3- phosphate-O-acyltransferase 5 (AGPAT5) enzyme converts lysophosphatidic acid to phosphatidic acid in the mitochondrial membrane. In this study, we found that the porcine AGPAT5 gene was highly expressed in muscle tissue, influencing meat characteristics, and we also identified a non-synonymous single-nucleotide polymorphism (nsSNP) (rs196952262, c.673 A>G) in the gene, associated with a change of isoleucine 225 to valine. The presence of this nsSNP was significantly associated with meat color (lightness), lower cooking loss, and lower carcass temperatures 1, 4, and 12 h after slaughter (items T1, T4, and T12 on the recognized quality scale, respectively), and tended to increase backfat thickness and the waterholding capacity. These results suggest that nsSNP (c.673A>G) of the AGPAT5 gene is a potential genetic marker of high meat quality in pigs.

Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.

The rates of solvolysis of trans-[Co(en)_2CL_2]^+ and trans- [Co(1,3-pn)_2CL_2]^+, in which en and 1,3-pn are ethylenediamine and 1,3-propylenediamine resepectively, have been investigated using conductometric and spectrophotometric methods at various pressures up to 2,000 bar in aceton-water mixture. The activation volumes obtained from the pressure effect on rate constants were small and positive values in both complexes of trans- [Co(en)_2Cl_2]^+ and trans- [Co(1,3-pn)_2CL_2]^+. These results are discussed in terms of dissociative mechanism (S_NI) for the solvolysis of both complexes. The importance of solvent composition on the reaction is further confirmed by application of a free energy cycle. It is concluded from the free energy cycle that the effect of solvation of transition state in the solvolysis of both complexes is more dominant than that of initial state. In addition to that, it is shown that the character of S_NI is further increased with increasing the content of acetone.

Background: Retrograde cardioplegia catheter (RCC) insertion is one of methods for administration of cardioplegics during cardiopulmonary bypass (CPB). However its success rate depends on only surgeon's experience. We thought the transesophageal echocardiography (TEE) can guide the R CC insertion, because TEE is commonly used for monitoring status of heart during cardiac surgery. This study was designed to evaluate the RC C insertion time by TEE guidance versus conventional method without T EE guidance. Methods: Sixty patients who were scheduled to undergo elective coronary artery bypass graft (CABG) surgery under general anesthesia were divided into groups as follows: group T [RCC insertion into coronary sinus (CS) by TEE guidance, n=30] and group C [RCC insertion into CS by conventional method, n=30]. We recorded the time of insertion of RCC in to CS in two groups. RCC insertion was done by TEE guidance in case that time was over two minutes by conventional methods in group C. Results: The overall time of RCC insertion into CS was 63.8 ± 23.6 seconds in the Group T and 102.3 ±55.7 seconds in the Group C, respectively (p=0.001). There were no complications during RCC into CS by T EE guidance. Conclusions: TEE guidance for RCC insertion into CS is shorten the time of insertion.

The rates of solvolysis of the complex ion, trans-Co(N-Eten)_2Cl_2+, in water-acetone mixture have been investigated using spectrophotometric method at various pressures and temperatures. The rate constants in aqueous acetone solutions are analyzed with the solvent compositions which gave been characterized in terms of Y parameter representing solvent ionizing power. The logarithms of rate constants are non-linearly correlated with parameter, Y. It suggested that the effects of solvent compositions on the reaction mechanism are important. The activation parameters are determined using transition state theory. The pressure effects on the rate of solvolysis of the complex have also been studied in water-acetone mixture, yielding +0.3~+1.5ml/M of activation volumes at 1~2,000bar and 25℃. The activation volumes are dependent on the solvent compositions and pressures. The established solvent composition of isoactivation volume are about 7%(v/v) acetone in this mixture.

This research is aimed to know how educating mass media to children has impacted on child-development by analyzing some data studied through. We suggested some questions for this conducting. First, what is the point issued by early media use to children? Second, How much has the study about children's computer use been done? We have drawn these conclusions. About the first question, early educators had pro and con to the media use and they had focused on popularity and use of new media. And then they have changed their focus to some effects or impacts of new media on child-development. For the second question, in our country as well as other countries, there have been some meaningful effects, a few negative sides and none effects to child-development. On the ground of education, the computer use has been adapted and applied to child-development with proper softwares fitted good topic or intention. Besides, many teachers have tried to have good interactions with their young students. But we are insisting one thing that more chances to make use of computer be given to young students at home and there be more connections between two educational fields- home and school.
