Ventricular septal defect is most common congenital cardiac anomaly in Korea and worldwide. And its clinical spectrum is well known. The anatomic classification had been undertaken by several authors, but recently Dr. Soto and Anderson's classification is widely used instead of Dr. Kirklin's it. From April. 1984 to December 1986, 99 cases of ventricular septal defects had been taken surgical repair under direct vision using conventional cardiopulmonary bypass technique at Yeungnam university hospital. The clinical spectrum was similar to other hospital, and the postoperative mortality was 2%, The most common associated anomaly was patent foramen ovale, and the most common postoperative complication was incomplete or complete right bundle branch block. The rank of defects was as followings: 45 perimembranous inlet type, 21 doubly commited subarterial type, 17, perimembranous trabecular type, and 16 perimembranous outlet type. There was no muscular and mixed type.

Purpose: In this study, we analyzed refractive power of school children in low income family. Methods: We have done a comparative analysis with 112 subjects of low-income of 17 elementary schools in the Yeongcheon area and low-income children less than -6 D of refractive errors from the Korean National Health and Nutrition Examination Survey Report 2010. Results: Spherical equivalent (SE) with low-income group of nation was -1.99 D for right eye and -1.81 D for left eye, while high income group of nation showed -1.26 D and -1.21 D for right eye and left eye respectively. The SE with low income group in Yeongcheon area was -1.85 D for right eye and -1.81 D for left eye. The SE with orphan was -2.75 D and -2.42 D. Single parent family was -2.10 D and -1.96 D, and two parent family was -1.75 D and -1.73. Conclusions: The lack of attention to children eye care may be one of cause for myopia, so the role of the parents and teacher is very important. However, limited role of parents to children due to low income, it is necessary to provide an institutional strategy and social interest to prevent children vision' in low income family.

In the era of the fourth industrial revolution, drones are being used in various civil engineering fields. Currently, the construction and maintenance of slopes are generally managed by manpower. This method has a risk of safety accidents, and it is difficult to accurately evaluate the slope because it is difficult to secure the vision. In this paper, the effects of RTK and GCP on the 3D model of the slope were studied by using digital images taken by the drone. GNSS coordinates were measured for nine points to compare the quality of the slope 3D model, three points of which were used as the check points and the remaining points were used as GCPs. When making the 3D model of the slope using high-accuracy geotagging images using RTK, it was found that the error at the check point decreases as the number of GCP increases. Even if GNSS was used, it was found that the error at the check points of the 3D slope model was not significant when the GCPs were applied. However, it was found that even if high-accuracy geotagging images are used using the RTK module, a significant error occur when the 3D slope model is created without applying GCPs. Therefore, it can be stated that GCP must be applied to create the 3D slope model in which information about the height as well as plane information is important.

This study was carried out to find out the possibility for developing methodologies on the index for forest sustainability and to assess sustainability indices of metropolitan and provincial districts based on conditions of their forest health and management programmes in Korea. To find out some indicators to be utilized in developing the forest sustainability indices, total 84 possible indicators were selected and combined from 69 major programmes contained in the 4th Forest Development Plan and the Forest Vision for 21st Century and other 15 indicators selected separately from other forest policies. Those candidate indicators were reviewed throughly under evaluation processes and 33 indicators were finally chosen in developing the forest sustainability indices. Those indicators were classified into 3 categories, namely indicators for pressure, state, and response. Forest health could be represented by pressure and state indicators, while forest management programmes could be assessed by response indicators. Scores of importance for each indicator were assigned through Delphi survey and analyzed to project the extra weight value by summing rankings given to each index an applied to the standardized value of each index. Forest sustainability indices of metropolitan and provincial districts were analyzed and compared, based on relevant data of the year 2002. This study was kind a preliminary one in forest sustainability index and the names of metropolitan and provincial districts were not identified in this study. The indices could be very valuable in assessing quantitatively the level of forest health and intensity of forest management programmes in each districts and comparisons could be made among them, if all self-governing districts agree unanimously on the indices of forest sustainability and relevant indicators chosen in the study.

Purpose: This study is intended to look into the difference in surgery effects through the analysis of risk factors on how the common adult diseases among Korean adults diseases (glaucoma, hypertension and diabetes) are affecting cataract. Methods: Cataract surgery patients' daily records at hospitals in Jeonnam were used as analysis data. Factors - which can affect the results of medical treatment before and after an operation - were classified into the input, process and outcome of medical treatment. The medical treatment and patient characteristics were reflected as the input of medical treatment, and clinical results, functional status and general status as the process of medical treatment. Results: There was a close relationship between adult diseases of glaucoma, diabetes and hypertension, and cataract. Visual acuity of adult diseases patients was 10% lower than of non-adult diseases patients. And for post-surgery it was around 16% difference in refractive error and visual acuity between two groups. Conclusions: According to a study result, the cataract has been confirmed that there is a close relationship of Adult disease patients's glaucoma, diabetes and hypertension. Depending on the type about these adult diseases, before and after cataract surgery, vision and refractive power was found to indicate a significant difference when compared with conventional low normal adult control.

This is a single group pre-post study conducted to confirm the effectiveness of HIV/AIDS education for nursing students, imparted via video-learning methods. Study participants enrolled were 93 students in the 4th grade of the Department of Nursing at J-City V University. Data were collected from May 26 to June 16, 2020, and were analyzed using descriptive statistics, paired t-test, independent t-test, ANOVA, and Pearson's correlation coefficient using the SPSS WIN 23.0 program. Results of this study confirm improvements in HIV/AIDS knowledge and attitude after attending video-learning modules. However, when assessing the details of attitude, insufficient data was obtained for difference in attitude toward social stigma recognition. Therefore, numerous attempts are required for imparting educational contents and methods that will positively alter social stigma recognition. The results of this study prove that video lectures are a useful teaching and learning method to transform the knowledge and attitude of nursing students towards HIV/AIDS. We believe that results obtained are meaningful, and provide a basis for imparting education by utilizing different media, such as a video-learning module.

The purpose of this study was to provide basic data on hand washing of physical therapists by examining their awareness and practice of hand washing according to proper clinical practice. A total of 536 questionnaires were collected from physical therapy students in Gwangju metropolitan city. The general characteristics of the subjects were calculated by frequency analysis, and the awareness and practice of hand washing with and without clinical practice were analyzed by independent t-tests. As a result of analyzing hand washing awareness according to the clinical practice, there was a significant difference in hand washing up to the wrist (p<0.05), and a significant difference in 6 stages of proper hand washing (p<0.01). As a result of analyzing hand washing practice according to clinical practice, there was a significant difference in hand washing before eating and starting clinical practice (p<0.05), a significant difference in washing hands after contacting clinical practice equipment and washing your fingers from your thumb down (p<0.01). As a result of analyzing the correlation between awareness and practice, most showed positive correlation. This means it is important to raise the awareness of proper washing hands. Therefore, it is believed that the training school should repeatedly conduct its own hand washing training within the school and in clinical practice to increase awareness and improve handwashing in clinical practice.
