  • 본 논문에서는 몇가지 규칙에 의해 ESOP(Exclusive-OR Sum-Of-Products) 함수를 간단화 하는 알고리즘을 제시하였다. 알고리즘은 두 개의 함수에 대한 곱항 변형 연산을 각 항의 상태에 따라 선택적으로 반복수행하여 간단화를 행하였다. 다치 입력 2치 다출력 함수를 최소화함으로써 입력 디코더를 이용하여 EXOR PLA를 입력의 최적화를 하였다. 4치 연산회로 함수에 본 알고리즘을 적용하여 EXOR형 논리회로를 설계하였고, 2bit 입력 디코더를 EXOR-PLA의 설계에 적용하였다. 컴퓨터 시뮬레이션(IBM PC 486 상에서 실행)을 통해 제시된 알고리즘을 여러가지 연산 회로에 적용한 결과, 함수의 입력 변수의 수와 관계없이 최소화가 가능하였고, 출력함수의 곱항수를 줄일 수 있음을 알 수 있었다.

  • The purpose of this study was to elucidate to what extent the goals of the leadership training program implemented in a medical college were achieved. Study subjects consisted of 74 first-year premedical students at the College of Medicine of The Catholic University of Korea. All participants completed two questionnaires: an 18-item self-leadership questionnaire asking self-expectation, rehearsal, goal setting, self-rewards, self-judgment and constructive thinking, and a 28-item self-efficacy questionnaire asking preference toward difficult work, efficacy of self-control, and confidence before and after the leadership training program. Students also competed a program satisfaction survey after the program. The collected data were analyzed with a paired t-test, descriptive statistics by IBM SPSS ver. 20.0 (IBM Co., Armonk, NY, USA). Students' overall satisfaction with the program scored 4.06 out of 5. The scores of self-leadership and self-efficacy increased after the leadership training program except for 'confidence' in self-efficacy. The results indicate that an intensive leadership program in a short period of time could help to enhance social competencies such as communication skills, empathy, self-reflection, and teamwork of premedical students.

  • Objectives: The purpose of this study was to determine the differences in quality of life between groups that promote oral health and those that treat oral diseases using data from the National Health and Nutrition Examination Survey. Methods: Data analysis was performed using IBM SPSS ver. 21.0 (IBM Co., Armonk, NY, USA). A total of 3,338 subjects were selected as subjects for the study before applying oral health promotion (OHP; 1,132 persons) and oral disease treatment (ODT; 2,206 persons). Complex sample logistic regression analysis was performed to determine the effects of OHP and ODT on health-related quality of life. Results: As a result of confirming the effect of OHP and ODT on the quality of life, which are indicators of the quality of life, HINT-8 had a significant effect even in Model 2, adjusted for demographic characteristics, with a significant difference (p<0.01). Conclusions: The above results confirmed that persons who promote oral health have a significant effect on HINT-8, a quality of life scale developed for Koreans. Therefore, continuous oral care is required to improve quality of life.

  • Background: This study was conducted to investigate factors related to unmet medical needs of medical care in adult diabetes patients and to suggest factors related to unmet medical in Korea. Methods: This study used data from the Korea National Health and Nutrition Examination Survey (KNHNES) 2014-2017. The subjects of the study were conducted on patients with unmet medical needs experience among the patients and analyzed using the IBM SPSS ver. 25.0 program (IBM Corp., Armonk, NY, USA). Results: Overall, 10.9% of patients had unmet medical needs. Being female, less educated, and lower medical aid were related to unmet medical needs. And subjects with poor subjective health and higher stress level were more likely to report unmet medical needs. Conclusion: Although comprehensive health insurance coverage, 10.9% of people with diabetes experienced unmet healthcare needs. The results of this study suggest that socioeconomic factors such as low education and medical aid were associated with unmet medical needs.

  • Purpose: The study aimed to collect data from patients who were rejected by emergency requests for transfer to a tertiary hospital through 119 EMT and to analyze the data in the hospital to improve the plan. Methods: We analyzed 4,702 cases of emergency requests made by patients who were rejected by 119 emergency assistance out of the 22,568 patients who visited the emergency medical center in the C area of G metropolitan city from January 2018 through December 2020. The collected data were analyzed using IBM SPSS Statistics Version XX (IBM Corp., Armonk, N.Y., USA). Results: The major medical department with the largest number of such cases was the department of emergency medicine, with 2,519 cases (53.6%). Simple bruises were the most common diagnosis, with 2,819 cases (61.2%). KTAS classification was the highest with 3,562 patients (75.8%) in grade 4. As for the results, 4,084 patients (86.9%) were discharged from the hospital. Conclusion: Most of the patients who were rejected by emergency requests were non-emergency patients and were discharged from the hospital. emergency requests must be rejected at public relations and sites. In addition, the law should be amended to specifically present the reasons for refusal of emergency requests.

  • Background: Iron is an essential element for women of reproductive age, especially in the period before and during the pregnancy. This study investigates the consumption of iron to prevent iron deficiency anemia among pregnant women visiting Neyshabur healthcare centers based on the theory of planned behavior. Methods: In this experimental study, data were collected through a questionnaire survey. It included 160 pregnant women who were receiving maternity services at twelve healthcare centers in the city of Neyshabur in Iran between 2015 and 2017. The participants' demographic and anthropometric characteristics, Using the theory of planned behavior, and blood lab examination results, including ferritin levels were measured and the data were analyzed using IBM SPSS ver. 22.0 (IBM Corp., Armonk, NY, USA). Results: The average scores of knowledge, attitude, perceived behavioral control, subjective norms, and intention categories for the intervention group were meaningfully increased after the participants received education on iron supplementation (P<0.05). However, these changes were not found to be significant in the control group (P>0.05). No statistically significant difference was obtained in the subjective norms category between the two groups after the education intervention (P=0.92). Conclusion: Based on the experimental effects of education encouraging iron supplementation in pregnant women, it is suggested that workshops promoting iron supplementation should be conducted in health centers with the aim of preventing widespread iron deficiency anemia.

  • Purpose: This study aimed to investigate disaster preparedness competence and disaster response competence of paramedics working in emergency medical centers operating a disaster medical assistance teams. Methods: Data of 174 emergency medical technician(EMT)-paramedics were collected from July 15 to August 14, 2018 at regional and local emergency medical centers that operate disaster medical assistant team. Analysis of the data was carried out with IBM SPSS statistics 24.0 software (IBM, Armonk, NY, USA). Results: The mean disaster preparedness competence score was $3.57{\pm}0.63$ (out of five). Participants' disaster preparedness competence significantly differed according to type of emergency medical center (p<.000), disaster education experience (p<.000), and education frequency (p=.001). The mean disaster response competence score was $4.09{\pm}0.57$ (out of five). Participants' disaster response competence significantly differed according to disaster education experience (p<.000) and medical assistance experience (p=.045). Conclusion: Emergency medical technician-paramedics without disaster training should first be provided with this training. Further, it is important for EMT-paramedics to know their disaster preparedness and response capacities and strengthen their shortcomings. It is also important to develop education and training programs that properly equip EMT-paramedics with practical competencies.
