A 10-month-old intact male Labrador Retriever dog was referred with the primary complaint of exercise intolerance, especially after vigorous exercise. Physical examination revealed split S1 and grade III/VI diastolic regurgitant murmur at the left apex and base, respectively. ECG finding was normal sinus rhythm at rest, but supraventricular tachycardia with bundle branch blocks after exercise. Thoracic radiography revealed dilated ascending aorta with normal range of cardiac silhouette (VHS 10.2). Echocardiography revealed abnormal valvular structures just above the aortic valvular cusps causing aortic regurgitation with a reduction of left ventricular ejection fraction (LVEF). Based on those findings, the case was diagnosed as congenital aortic regurgitation caused by abnormal valvular structures. The dog was managed with diltiazem and exercise restriction. This is a rare case of aortic deformity in dogs.

The objectives of this study were to examine the production processes and methods of "Forest Type Map Actualization Production (Database (DB) Construction Work Manual)" (Work Manual) identify issues associated with the production processes and methods, and suggest solutions for them by applying evaluation items to a 1:5k digital forest type map. The evaluation items applied to a forest type map were divided into zoning and attributes, and the issues associated with the production processes and methods of Work Manual were derived through analyzing the characteristics of the stand structure and fragmentation by administrative districts. Korea is divided into five divisions, where one is set as the area changed naturally and the other four areas set as the area changed artificially. The area changed naturally has been updated every five years, and those changed artificially have been updated annually. The fragmentation of South Korea was analyzed in order to examine the consistency of the DB established for each region. The results showed that, in South Korea, the number of patches increased and the mean patch size decreased. As a result, the degree of fragmentation and the complexity of shapes increased. The degree of fragmentation and the complexity of shapes decreased in four regions out of 17 regions (metropolitan cities and provinces). The results indicated that there were spatial variations. The "Forest Classification" defines the minimum area of a zoning as 0.1ha. This study examined the criteria for the minimum area of a zoning by estimating the divided object (polygon unit) in a forest type map. The results of this study revealed that approximately 26% of objects were smaller than the minimum area of a zoning. The results implied that it would be necessary to establish the definition and the regeneration interval of "Areas Changed Artificially and Areas Changed Naturally", and improve the standard for the minimum area of a zoning. Among the attributes of Work Manual, "Species Change" item classifies terrain features into 52 types, and 43 types of them belong to stocking land. This study examined distribution ratios by extracting species information from the forest type map. It was found that each of 23 species, approximately 53% of species, occupied less than 0.1% of Forested land. The top three species were pine and other species. Although undergrowth on unstocked forest land are classified in the terrain feature system, their definition and classification criteria are not established in the "Forest Classification" item. Therefore, it will be needed to reestablish the terrain feature system and set the definitions of undergrowth.

This paper is the first paper among two papers which constitute the paper about the structural design of a dental implant. This paper surveyed types and characteristics of dental implants. Merits and shortcomings of clinically used dental implants were analysed through this survey. A new structural model of dental implant was proposed on the basis of survey results. Especially, a comparative structural analysis of the new dental implant and the well known dental implants has been performed using the finite element analysis method. The analysis results confirm that the newly proposed dental implant has a good structural performance. The well known dental implants used for the comparative structural analysis are 3i implant and Sargon implant. These implants are imported dental implants and we could know that most implants clinically used are endosteal implants and these two implants(3i implant and Sargon implant) are also endosteal implants.

This study is a methodological research study that tests the validity and reliability of the NCRC (Nurse Clinical Reasoning Competence scale), an instrument developed by Liou and his colleagues as the basic data for enhancing the clinical reasoning competence of nurses, by translating it into Korean and checking the similarity of the sentence structure and meaning (between the two versions?). This study verified its validity and reliability by examining 166 nurses working in four tertiary hospitals located in Seoul and Busan. An analysis of the content validity by experts showed that all of the items have a content validity higher than CVI 0.8. From the exploratory and confirmatory factor analysis, it was found that the instrument includes a total of 15 items consisting of one factor. In addition, the correlation with the Korean version of the Nurse Clinical Reasoning Competence scale is confirmed to test the concurrent validity, by using a measurement tool of nurses' critical thinking dispositions and clinical decision-making abilities (correlation coefficient =.55-.64(p<.001) and Cronbach's ${\alpha}=.93$). Thus, the Korean version of the NCRC may be a useful instrument for evaluating the clinical reasoning competence of Korean nurses and providing the basic data for assessing their clinical reasoning competence and developing their promotion strategies.

Purpose. The purpose of this study was to investigate effects of preclinical OSCE(Objective Structured Clinical Evaluation) on knowledge, confidence in their Core fundamental nursing skills and self-efficacy in nursing students. Method. The research design was a one group pretest-posttest design and it was done to assess changes in knowledge, confidence in core fundamental nursing skills and self-efficacy from pre to the post-test which was given after the OSCE. Data were collected from March 5 to April 7, 2016 from 37 nursing students who were taking the 15-hours using OSCE learning module at one Gyeongbuk-do, P-city. This practicum was composed of 4 core fundamental nursing skills and 5 other fundamental nursing skills. The knowledge consisted of a 10-item by researchers and the confidence of core fundamental nursing skills consisted of an 9-item NRS and the self-efficacy consisted of a 17-item 5-point scale and measured in both the pretest and posttest. The collected data were analyzed with SPSS IBM 20.0 program for the frequency, percentage, x2-test, and paired t-test. Rusult. The results showed that although scores of knowledge of OSCE learning module were significanlty increased from 5.22 to 7.03(t=5.30, p<.001). There were significantly increased in scores of confidence in core fundamental nursing skills from 5.13 to 7.27(t=10.01, p<.001), In the sub-scales of each core fundamental nursing skills was scored the highest. otherwise, there was no significant difference in self-efficacy(t=1.42, p=.161). Conclusions. Based on the results, this study suggests that OSCE module development activities for nursing students in nursing education-learning in order to improve nursing skills.

Gross examination techniques (GETs) of specimens collected from cancer surgery or endoscopy comprise the act of recording visual information about cancer for accurate histopathological diagnosis and collecting sections of the lesion to create microscopic specimens. GETs must include concise and accurate expressions, appropriate structuring, sufficient resections, error-free standardization of important information, and photo-diagramming of complex specimens. To increase the satisfaction of pathological interpretation, it is a task that must be performed accurately and carefully to gain confidence on a theoretical and practical basis with a sufficient understanding of gross examination. Based on the experience of clinical pathologists in the field of GETs, additional specimen types should be identified as viable candidates. Also, their needs and concerns regarding treatment should be carefully considered. In addition, departments at each institution should review the national focus on clinical partnerships, continuous professional training, diagnostic errors, and value-based healthcare provision.

The purpose of this study is to discover unique personality traits which the children of 5 social status types using 10 clinical scales of Korea Children's personality test (KCPI-S) in order to define the characteristics of 5 social status types developed as the Korean type. For this purpose, two hypotheses were set and tested. The subjects of this study were 502 children who were 4, 5th and 6th grade elementary school boys and girls in A city. 5 social status types and gender of children were set as the independent variables each, and 10 clinical scales of Korea Children's personality test as the dependent variables. The research hypotheses were analyzed in turn by the multivariate analysis (MANOVA) and t-test. The results are as follows: First, the results of analyzing differences in 10 clinical scales in accordance with 5 social status types how the significant differences in all 9 clinical scales except for language development scale, and ${\eta}^2$ representing the explanatory power of the independent variables to dependent variables was found to be in the range of the lowest at 2% up to 10% for each scale. Second, the results of analysis of the gender difference show that in the case of the children with controversial and neglected children, the significant difference was appeared between boys and girls in 8-9 scales among the 10 clinical scales, but in the case of rest 3 social status types (average, popular, rejected children) the difference was appeared between boys and girls only in 2-3 scales. Depending on these results it seems that each of 5 social status types of the children has its own unique personality structure. It is necessary to attend to the fact that in the case of the children with controversial and neglected children, the average value of boys are significantly higher than that of the girls. There is a big possibility that the boys have more psychological problems that the girls. It is judged that in case of these two types the personal traits applying gender should be interpreted. Therefore, the follow-up study should conduct the exploratory research on the structure of the relationship between children's language development and sociality measure. Further, it is necessary to conduct the psychological comparison between genders in the children with controversial and neglected children, and to study the structure of their relationship with rest social status types by genders.

In this study, the sterilization ability of S. aureus and P. aeruginosa was evaluated using a plasma generator with a flexible electrode structure. Both strains were prepared at a concentration of 1.5×106 CFU/mL and inoculated and spread evenly on two medium plates. The medium were kept at a distance of 3 cm and 9 cm from the plasma generator and were plasma discharged from 30 sec to 10 minutes. The growth of colonies on the media, were subsequently compared with the control group. The mean colonies of S. aureus formed at a 3 cm distance were 9.2×102 (log value 2.96) CFU/mL for the 5 min discharge period and 8.0×10 (1.90) CFU/mL for the 10 min discharge period. When the medium was exposed for 5 min and 10 min at a 9 cm distance, the mean colonies of S. aureus formed were 2.16×103 (3.33) and 2.4×102 (2.38) CFU/mL, respectively. The medium containing P. aeruginosa kept at a 3 cm distance and exposed to 3, 5, 10-minute discharge, did not form any colonies. When kept at a 9 cm distance for 3 minutes, 6.0×102 (2.78) CFU/mL mean colonies were formed but no colonies were formed at exposure periods of 5 and 10 minutes. This enhanced sterilization effect was confirmed in experiments of S. aureus and P. aeruginosa using TiO2.

A bioterrorism attack(BT) attack is the deliberate release of viruses, bacteria, fungi, and toxins used to cause illness or death in people, animal, and plants. Therefore, the healthcare workers are those who will take the main role in BT outbreak situations. The purpose of this study is to investigate current status of education for BT preparedness and response in health-related colleges. It is important to provide the BT preparedness and response to the health-allied students in case of unexpected BT outbreak. The questionnaires were collected from March 10 to June 10 in 2007 via mai l. Approximately 97.6% of the health-related professors answered that they had no experience of bioterrorism education. The contents of the bioterrorism curricula should contain the followings : definition and characteristics of the emergency and disaster, definition of bioterrorism, history of bioterrorism, general characteristics of bioterrorism, etiological agents of bioterrorism, bioterrorism response, systematic response, and medical response. Through these data, we will develop the disaster and bioterrorism preparedness curricula.

Objectives : The purpose of this study is to evaluate the role of structural and functional changes of the brain in the pathophysiology of schizophrenia. Methods : The authors measured the regions of interest on the magnetic resonance imaging of the brain in 20 patients with paranoid schizophrenia(15 men and 5 women) and 23 control subjects(15 men and 8 women). We also assessed the neurocognitive functions with the Wisconsin Card Sorting Test, the Benton Neuropsychological Assessment, and the Weschler IQ test-Korean version, soft neurologic signs, and psychiatric symptoms in the patient group. Results : In the patient group, all ventricles and basal ganglia including caudate nucleus and globus pallidus were significantly enlarged. Although there were no significant differences between the two groups in the values of right frontal lobe and left temporal lobe, there was a tendency of decrease in the values of right frontal lobe and left temporal lobe. There were significant positive correlations between the values of ventricles and the frequency of previous hospitalization. However, there were no significant correlations between other values of regions of interest and clinical data. The value of the right frontal lobe was significantly correlated with the score of soft neurologic signs, which is suggestive of the neurodevelopmental abnormalities. There were significant correlations between the value of frontal lobe and the scores of the various subscales of Benton Neuropsychiatric Inventory. In contrast, the value of left amygdala and putamen showed significant correlation with the score of verbal IQ on the Weschler IQ test. Structural changes of the temporal lobe areas were related with the positive and general symptom scores on PANSS, while those of the basal ganglia were related with the negative symptom scores. Conclusions : These results suggest that the structural changes of the brain in the patients with schizophrenia show the dual process, which is suggestive that the enlarged ventricle show the neurodegenerative process, while enlarged basal ganglia, and shrinked right frontal and left temporal lobe show the neurodevelopmental abnormalities. Among these changes, structural changes of the frontal lobe related with various neuropsychological deficits, while those of left temporal lobe related with language abnormality. Relative to the relation between structural changes and psychiatric symptoms, structural changes of the temporal lobe areas were related with the positive and general symptoms, while those of the basal ganglia were related with the negative symptoms.
