  • In the preoperative evaluation before coronary artery bypass surgery, review of the coronary arteriogram is the most important step. Expected "normal" lumen diameter at a given coronary anatomic location is a basis for quantative estimation of coronary disease severity that could be more useful than the traditional "percent stenosis". The distribution and number of major coronary artery branches are determinants of number of bypass grafts needed. We reviewed the coronary artery anatomy in 174 adult patients who revealed no coronary pathology in angiographic studies done from September 1994 to June 1996. Quantative analysis was done in all cases by a single person using a Computerized System (Arripro 35ⓡ). The results were follows; 1) The mean diametre of left main coronary artery was 4.45 mm(range 2.74~6.72). The pattern of branching was bifurcation in 67.24%, trifurcation in 28.74% and quadrifurcation in 4.02% of the patients. 2) The mean diametre of left anterior descending artery was 3.17 mm(range 2.10~5.85), 2.79 (range 1.55~5.59) and 2.17 mm(range 1.37~3.81) in the proximal, mid, and the distal portions, respectively. The number of diagonal branches of left anterior artery was from one to four(mode=2). 3) The mean diametre of proximal and distal left circumflex artery were 3.17mm(range 1.74~4.89) and 2.19 mm(range 1.21~4.46). The number of obtuse marginal branches of left circumflex artery is from one to six(mode 2). 4) The mean diametre of proximal and distal right coronary artery, the posterior descending artery and the largest posterolateral branch were mean 3.51 mm(range 2.07~5.67), 2.09 mm (range 1.42~3.60), 2.09 mm(range 1.02~3.60) and 2.30 mm(range 1.39~4.39). 5) The right coronary artery dominant was 163 cases(93.68%) of the total 174 cases. 6) The large significant acute marginal artery was visualized in more than half of the people. half of the people.

  • This study aims to explore the issues of residential care services for children and youth with disabilities using mixed methods research. In Korea, welfare policies for people with disabilities tend to focus on adults with disabilities. As a result, children and youth with disabilities often receive less attention in welfare policies, which is especially true of children and youth with disabilities at residential facilities, who have confronted more serious situations than children and youth with disabilities living together with their families. Thus, the goal of this study explores the issues of residential care services for children and youth with disabilities, and suggests alternatives grounded in the research results. This study used a mixed methodology; in particular the embedded design that is designed by Creswell and Clark(2007). In qualitative research, representative professionals who work at residential facilities were selected using the recommendations of professional groups, and were interviewed using focus group interview methods. In quantitative research, this study investigated the thoughts of professionals on the issues of residential care services for children and youth with disabilities, using questions that were developed through qualitative research results. This study is significant in that it explored the issues of residential care services for children and youth with disabilities, focusing on field experiences, for the first time in Korea, and suggested political alternatives for the future.

  • Telomeres consist of TTAGGG tandem repeated DNA sequences with specific proteins and locate at chromosome ends. Telomeres are essential for chromosome stability and are related with cell senescence, apoptosis and cancer. Telomerase is a ribonucleoprotein which has a template for the synthesis of telomeric DNA. This study was carried out to analyze the amount of telomeric DNA and telomerase activity in cattle cells. Analysis of the quantity of telomere in lymphocytes was done at different ages, sex and among Korean cattle and Holstein breeds. The telomerase activity was also analyzed in liver, brain, heart, kidney, and testis tissues of fetal calf and of 18 month old cattle. The amount of telomeres in lymphocytes and other tissue cells was analyzed by Quantitative-Fluorescence in situ Hybridization (Q-FISH) technique using a telomeric DNA probe. Telomerase activity was analyzed by Telomeric Repeat Amplification Protocol assay (TRAP). The amount of telomeric DNA on the lymphocytes during the whole life span was decreased along with age. Quantity of telomeres in Korean cattle was significantly higher than that in Holstein breed. The amount of telomeric DNA in males was significantly higher than that in females. Telomerase activity was up-regulated in most bovine tissues during fetal stage, but was down-regulated in most tissues at mature 18 month age except the testis cells. This study indicates that the amount of telomeres and telomerase activity of cells can be used as an age marker or/and a physiological marker of cattle.

  • The purpose of this study is to improve interaction with the construction subject by analyzing the contents and contents of users' involvement in landscaping works. For this purpose, this study selected the Gwanggyo Residential Land Development District Public Landscape Project in Suwon, Gyeonggi Province. For four years before and after the completion, the opinions of tenants were used as research data. Both qualitative and quantitative analyses of 412 complaints received by the project implementation office and local government were conducted. As a result, first, the main purpose of suggesting opinions was 'demanding and expressing complaints', and there were many 'parks' and 'rivers'. In terms of content, "quality" was the most pointed out, but many kinds of trees, such as tree planting, ecological river construction, and pavement construction were also mentioned. Second, the extraction of key words from content analysis was the most common method. Followed by 'additional foodstuff' and 'moving to the toilet and management building'. Much of the point of view about dead wood has continued to be conspicuous in the process of waiting to be dealt with at the time of transplanting. Third, the validity of the contents of the complaints was evaluated as a five - point scale. Therefore, the opinions raised were unreasonable, but overall, there were more complaints with certain objectivity.

  • The court-mandated spouse abusers with drinking problems not only resist and complain about taking the court-mandate but also have the low motivation to change their problem drinking and violent behaviors. Therefore, in this study the program is developed to decrease violent behaviors of spouse abusers with drinking problems. Also, the usefulness of this program is examined by quantitative and qualitative methods. The results are as follows: The experimental group's pre-to-post variation is decreased by significant level statistically more than the comparison group's variation in drinking problems. Regarding violent behaviors among groups, the experimental group's pre-to-post and pre-to-followup variation are decreased significantly. It is assumed that Motivation Enhancement Therapy(MET) influences the differences of motivation to change violent behaviors in both groups. The reason is that MET is considered to have influences on the group's dynamics and interaction. Also, it is helpful to change the negative emotions to the positive emotions and to stimulate the group interaction and the participation. This study will be contributed to promote the speciality on providing services for family in a domestic violence in Korea. Through this study, I suggested future implications in research, practice, and political side on spouse abusers with drinking problems.

  • The purpose of this study is to contribute to the study of the prevention of diseases and promotion of health of ocean going vessel crew members, through the medical diagnosis and disease classification efforts of this study. From the second half of 2016 to 2017, the diagnosis and health characteristics of 195 crew members were collected through counseling, treatment, and emergency care for about 1 year and 2 months. As a result, it is noted that the incidence of diseases was in the order of urticaria (5.6%), lumbar sprain (4.1%), acute gastroenteritis (3.1%) and anxiety (3.1%). In categorical review, the incidence of musculo-skeletal disease was the most common (25.1%) which was followed by skin disease (17.9%) and digestive disease (11.3%). In addition, the disease that was noted as was the most common in the under 30 years old category, and the incidence of the disease was high in the crew group. Finally, there was a difference between the pathogenesis (trauma vs disease, etc.) (p <.001) and the type of vessel (merchant ship and fishing vessel) (p <.005) as noted in this case.

  • Since late 2016, protectionism has been a major trend in world trade with the Great Britain exiting the European Union and the United States electing Donald Trump as the 45th president. Consequently, there has been a huge public outcry regarding the negative prospects of heavy industry firms in Korea, which are highly dependent upon international trade with Western countries including the United States. In light of such trend and concerns, we have tried to predict business performance of heavy industry firms in Korea with data regarding trade policy of the United States. United States International Trade Commission (USITC) levies countervailing duties and anti-dumping duties to firms that violate its fair-trade regulations. In this study, we have performed data analysis with past records of countervailing duties and anti-dumping duties. With results from clustering analysis, it could be concluded that trade policy trends of the Unites States significantly affects the business performance of heavy industry firms in Korea. Furthermore, we have attempted to quantify such effects by employing long short-term memory (LSTM), a popular neural networks model that is well-suited to deal with sequential data. Our major contribution is that we have succeeded in empirically validating the intuitive argument and also predicting the future trend with rigorous data mining techniques. With some improvements, our results are expected to be highly relevant to designing regulations regarding heavy industry in Korea.

  • The financial industry in South Korea has witnessed a paradigm shift from selling traditional loan/deposit products to diversified consumption channels and financial products. Consequently, personification of financial services has accelerated and the value of finance-related personal information has risen rapidly. As seen in the 2014 card company information leakage incident, most of major finance-related information leakage incidents are caused by personnel with authorized access to certain data. Therefore, it is strongly required to confirm whether there are problems in the existing access control policy for personnel who can access a great deal of data, and to complement access control policy by considering risk factors of information security. In this paper, based on information of IT personnel with access to sensitive finance-related data such as job, position, sensitivity of accessible data and on a survey result, we will analyze influence factors for personnel risk measurement and apply data access control policy reflecting the analysis result to an actual case so as to introduce measures to minimize IT personnel risk in financial companies.

  • The purpose of this study is to identify the psychological characteristics of the elderly and to investigate the variables that affect the life satisfaction of the elderly. To achieve this purpose, psychological characteristics such as self-esteem, alienation, loss, and depression were selected. A survey was conducted on the elderly living in Gwangju Metropolitan City. A total of 218 copies were collected and 203 copies were analyzed, excluding poor responses. To draw the results of the research, quantitative analysis was conducted through questionnaires, and SPSSWIN 21.0 statistical program was used as an analysis tool. The analysis methods were frequency and ratio analysis, technical statistical analysis, bivariate correlation analysis, and linear regression analysis. The results of the analysis are as follows: First, the relationship between the psychological characteristics of the elderly showed significant correlations among the self-esteem, alienation, loss, depression, and life satisfaction of the elderly. Second, for the elderly, alienation and depression had a negative effect on life satisfaction, and self-esteem had a positive effect on life satisfaction. However, loss did not have a significant effect on life satisfaction. In conclusion, it suggests that it is necessary to develop and operate policies and programs to improve self-esteem and reduce alienation and depression in order to improve the quality of life of the elderly.
