  • This study was undertaken to determine the degree of quality of life, and factors influencing osteoarthritis in hypertensive elderly 65 years or older patients, using data from the 7th National Health and Nutrition Survey 2018. Totally, 843 subjects were included from a national sample. The SPSS WIN 26.0 program was used to analyze complex samples by applying the Rao-Scott chi-square test, t-test, and multiple regression analysis. Results indicate that quality of life of the hypertensive group with osteoarthritis is significantly lower than the group with only hypertension (t=5.07, p<0.001). Factors affecting the decrease in quality of life of the hypertensive group were age, subjective health status, and activity restrictions, and the explanatory power was 46.1% (F=12.33, p<0.001). In the hypertensive group with osteoarthritis, the effective factors included gender, cohabitation status, economic activity, subjective health status, activity restriction, body mass index, sleep time, stress perception, and depression, and the explanatory power was 44.6% (F=99.82, p<0.001). Subsequent studies showed that in order to improve the quality of life of hypertensive seniors, intervention programs are required to actively accommodate health conditions and minimize activity restrictions. In addition, for the elderly with osteoarthritis and hypertension, it is necessary to include exercise and nutrition education for body mass index management, and the development and intervention of multidisciplinary participation programs to strengthen mental health.

  • This study conducted a secondary analysis by using original data of performed by Korea Institute for Health and Social Affairs to determine factors affecting health-related quality of life in the elderly. The results were as follows. For medical health condition, it became longer in endocrine diseases and cardiovascular diseases. In the case of functional health condition, subjects with musculoskeletal diseases showed higher functional health condition. Subjective health condition, while it became worse in digestive diseases and musculoskeletal diseases in the order, it recorded the best score when subjects did not have any musculoskeletal disease. Quality of life, while it became lower in endocrine diseases in the order, it was the highest when subjects did not have any musculoskeletal disease. Thus, increase of subjective health status for the elderly is important in the future.

  • In this paper, we propose the basic data for cancer patient management by secondary analysis of data from the National Health and Nutrition Survey(KNHANES) to identify factors related to suicidal thinking of cancer patients over 19 years of age in Korean adults lapse of time. The data were analyzed using the IBM SPSS WIN 22.0 program in order to analyze the demographic, health, and mental characteristics of the subjects in 2009 and 2017. It was analyzed using logistic regression analysis. As a result of the study, the factors related to suicidal thinking in cancer patients were activity restriction and experience of depression in 2009(Negelkerke R2=.384), and age, marital status, activity restriction, and experience of depression in 2017(Negelkerke R2=.525). This study is meaningful in that the factors related to suicidal thoughts in cancer patients were identified according to the lapse of time, and the changes in the related factors were confirmed. Development and application of an intervention program to prevent suicide in cancer patients are necessary.

  • Gifford(1992, 1993, 1997, 1998)는 제한적 주의력(limited attention)의 관점에서 벤처경영자, R&D 관리자, 혁신자, 벤처 캐피탈의 의사결정을 연구하였다. 창업경영자 (entrepreneurs)는 기술 개발, 제품디자인 개발, 원자재 확보, 제품 생산, 유통채널 확보, 가격정책 결정, 판매촉진 및 마케팅정책 결정 등의 다양한 경영활동을 수행하고 끊임없이 창업기회(entrepreneurial opportunities)를 추구하는 사람이다. Gifford 는 벤처 경영자를 창업기회와 다양한 경영활동의 포트폴리오(portfolio)를 수행하고 관리하는 대리인으로 간주한 '마술사 모형(Juggler model)' 을 제시하고 이익극대화의 관점에서 대리인의 의사결정을 분석하였다. 그녀는 모형을 통하여 특정시점을 지난 기존 메뉴를 포기 하고 새로운 창업기회를 평가하는 '포기정책(discard policy)' 과 아울러 기존 메뉴를 관리한 이후 새로운 창업기회를 평가하는 '연령검사(age inspection)' 를 동시에 사용한다는 결과를 도출하였다. 본 논문은 Gifford의 마술사 모형(Juggler model)을 수정, 발전시켜 창업경영자의 의사결정을 분석하였다. Gifford의 모형은 성장하지 않는 창업기회의 포트폴리오 결정에 대한 모형이기 때문에 창업기회의 성장성이 벤처경영자의 의사결정에 어떤 영향을 미치는가에 대한 논의가 전혀 없었다. 본 논문에서는 창업경영자를 기업가적 활동을 수행하는 사람으로 정의하고 벤처경영자의 의사결정을 분석하였다. 성장률이 큰 기업에서 기업가적 활동을 수행할 때 창업경영자가 창출하는 기업의 현재가치는 크게 증가하게 되는 반면 성장률이 떨어지는 기업에서 기업가적 활동을 수행할때 창업경영자가 창출하는 기업의 현재가치는 크게 감소하게 된다. 또, 창업경영자는 성장률이 큰기업을 선택하면 관리횟수가 줄어들게 되고 이익의 감소 없이 빠르게 수확할 수가 있다. 국가의 정책과 제도가 창업경영자를 보다 성 장률이 높은 기업에서 기업가활동을 하게 한다면 국가경제의 성장속도는 빨라지게 될 것이다.

  • In order to investigate the effects of a decreased activity on skinfold thickness, circumference and muscle strength of the extremities during the recovery period following heart surgery, skinfold thickness, circumference and muscle strength of the extremities were measured on days 0, 3, 6, and 9 following the surgery, and compared with those on the arrival day of intensive care unit. Skinfold thickness was measured using a skinfold caliper(Saehan Cor., Korea), circumference of the limbs were measured with a tape measure, upper extremity strength was determined using the Takei grip dynamometer and lower extremity strength was measured by pressing the flatfoot on an electronic digital health meter while tying on a bed. Results from this study were thus : 1. Skinfold thickness of triceps, quadriceps and gastrocnemius muscle on days 3, 6, 9 following the heart surgery was not significantly different from that of on the day of operation. 2. Circumference of midupperarm and midthigh on days 3, 6, 9 following the heart surgery was not significantly different from that of on the day of operation. Circumference of midcalf on days 3, 6 following the heart surgery was not significantly different from that of on the day of operation, while that of midcalf on day 9 following the surgery decreased significantly compared with that of on the day of operation. 3. Muscle strength of the upper extremity was not significantly different from that of on the day of operation, while that of the lower extremity on day 9 following the surgery decreased significantly compared with that of on the day of operation. From these results, it may be concluded that circumference and muscle strength of lower extremity can be decreased due to the postoperative inactivity following heart surgery in congenital heart disease children.

  • This study recognizes it as a social problem that can be prevented by basic research on safety security design for the elderly, and aims to clearly analyze risk factors for injury. For this study, raw data from the 6th Korean National Health and Nutrition Survey were employed and analyzed. Their social characteristics were classified with standards including gender, education, EuroQoL(human locomotion, normal activity and pain uncomfortableness), the quality of life(PHQ-(1)(2)(4)), recognition on stress, activity restriction status and associated causes(bone fracture and joint injury). Their epidemiological traits were chronic diseases, 'diabetes and hip-joint pain', and health-behavioral traits were 'smoking, breakfast frequency and high-level physical activity status.' In conclusion, it can be found that damage risk of elderly rose in case of female, lower education, inconvenience or limitation, pain or discomfort in locomotion and daily activities, higher recognition of stress, lower interest in work, feeling of depression, despair, and weariness, restriction in activity caused by bone fracture and joint injury, having diabetes and hip-joint pain, smoking, low frequency in having breakfast and high-level physical activities. Based on this study, we envision that an effective solution for injury risk factors caused by the organic relation can be reached in the near future.

  • Based on data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted by Korea Centers for Disease Control & Prevention (KCDC), this study analyzed the relationship between existence of the spouse, number of family members, and disease afflictions of the Korean elderly, and factors affecting their quality of life. The collected data were analyzed by Chi-square test, t-test and One-way Anova, using the SPSS / WIN 25. Our comparative analysis on the health status and quality of life revealed that individuals in the singles group had significantly more diseases than the married group. The singles group considered their health was subjectively poor, whereas the quality of life of the married group was higher. Analyzing the characteristics of chronic disease and activity restriction showed significantly higher prevalence of several diseases in the singles group. Besides, the singles group revealed significantly higher limitations of activity. Taken together, our results reveal a difference in the health status, quality of life, and the presence of chronic diseases in accordance to existence of the spouse, indicating that having a spouse increases the level of health and quality of life of the elderly.
