  • Background and Objectives : Quality of life(QOL) is a construct representing physical, mental and social well-being. QOL has been used as a device for measuring the severity of health-related condition and treatment outcomes. As the social welfare system develops, the attention to QOL increases as well. The aims of this study was to examine whether the patients with voice disorder perceived significantly more the effects of voice disorder on QOL than nonpatient group did and if any, identify the sociodemographic risk factors influencing QOL of patients. Materials and Methods : This study asked 113 adults with voice disorders who were enrolled in Voice Clinic in the Department of Otolaryngology, Kangbuk Samsung Hospital between lune 1998 and January 1999 and 111 nonpatients to complete a questionnaire designed to elicit information about the effete of voice disorders on quality of lift. The questionnaire included items concerning sociodemographic areas, voice symptoms, job, effects of voice disorders on QOL domains(work, social, psychological, physical, and communication areas), potential risk factors to exposures, familial and medical history of voice disorders. Results : The sociodemographic characteristics of the patient group are as follows : (1) 75.2% of total patient group were female and the rest were male. (2) Age of total patient group ranged from 20 to 65 years. Hoarseness was the most commonly reported complaints, followed by complaints of high note difficulties during singing and voice fatigue. The patient group perceived effects of voice disorders on the areas of work, social, psychological, physical and communication more adversely than the comparison group did (p<0.05). QOL impairments were evaluated as a function of age, gender, education, and income, controlling other independent effects. The results were that (1) age was significantly associated with work problems and (2) gender and income were significantly associated with psychological problems. Conclusions : The findings indicated that the patients with voice disorders would perceive markedly adverse effect on all QOL domains, that is, work, social, psychological, physical, communicational areas. Therefore, the results of study suggest that lurker investigations about the nature of voice disorders, the prevention, treatment, and coping strategies are needed in the future.

  • Most of the recently developed robots are human friendly robots which imitate an animal or human such as entertainment robot, biomimetic robot and humanoid robot. Interest in these robots is increased because the social trend is focused on health, welfare, and graying. By these social backgrounds, robots become more human friendly and suitable or home or personal environment. The more biomimetic robots resemble living creature, the more human feels familiarity. Human feels close friendship not only when feeding a pet, but also when watching a pet having the food. Most of entertainment robots and pet robots use internal-type batteries and have a self-recharging function. Entertainment robots and pet robots with internal-type batteries are not able to operate during charging the battery. So far there have been a few robots that do not depend on an internal battery. However, they need a bulky energy conversion unit and a slug or foods as an energy source, which is not suitable for home or personal application. In this paper, we introduce a new biomimetic entertainment robot with autonomous eating functionality, called EPRO-1(Eating Pet RObot version 1). The EPRO-1 is able to eat a food (a small battery), by itself and evacuate. We describe the design concept of the autonomous eating mechanism of the EPRO-1, characteristics of sub-parts of the manufactured mechanism and its control system.

  • The purpose of this study was to analyze big data to identify the sub-dimensions of ethical consumption, as well as the consumption value associated with ethical consumption that changes over time. For this study, data were collected from Naver and Daum using the keyword 'ethical consumption' and frequency and matrix data were extracted through Textom, for the period January 1, 2016, to December 31, 2018. In addition, a two-way mode network analysis was conducted using the UCINET 6.0 program and visualized using the NetDraw function. The results of text mining show increasing keyword frequency year-on-year, indicating that interest in ethical consumption has grown. The sub-dimensions derived for 2014 and 2015 are fair trade, ethical consumption, eco-friendly products, and cooperatives and for 2016 are fair trade, ethical consumption, eco-friendly products and animal welfare. The results of deriving consumption value keywords were classified as emotional value, social value, functional value and conditional value. The influence of functional value was found to be growing over time. Through network analysis, the relationship between the sub-dimensions of ethical consumption and consumption values derived each year from 2014 to 2018 showed a significantly strong correlation between eco-friendly product consumption and emotional value, social value, functional value and conditional value.

  • Purpose : To evaluate the effect of comprehensive art therapy on physical function and activities of daily living in children with cerebral palsy (CP). Methods : Ten ambulant children with diplegic (n=8) or hemiplegic (n=2) CP participated in this study. All were randomly assigned to either the art therapy group (n=5) or the control group (n=5). Both groups received physical therapy based on neurodevelopmental techniques for 20 minutes a day, 1 day a week, for a period of 12 weeks. Children in the art therapy group received additional comprehensive art therapy for 70 minutes once a week for 3 months. Tests for various measurements-Motricity Index (MI) for strength, Trunk Control Test (TCT) for trunk ability, Gross Motor Function Measure (GMFM) and Gross Motor Function Classification System (GMFCS) for gross motor function, Denver Developmental Screening Test-II (DDST-II) for developmental milestones, Functional Independence Measure of Children (WeeFIM) for abilities to complete daily activities, Leg and Hand Ability Test (LHAT) for limb function-were performed before and after treatments. Results : The upper extremity and whole extremity strengths of MI, self-care and total scores of WeeFIM, and leg and arm functions of LHAT improved significantly only for individuals in the art therapy group after the art therapy (p<.05). The value of MI after treatment was at the upper extremity and whole extremity strengths the leg function of LHAT was also significantly improved compared to the control group (p<.05). Conclusion : This study revealed that comprehensive art therapy along with physiotherapy was effective in increasing upper extremity strength and leg ability in children with CP. This suggests that comprehensive art therapy may be a useful adjunctive therapy for children with CP.

  • Objectives: Previous studies have found that the oral health of seniors can affect their physical nutrition and quality of life (QoL). Additionally, poor oral health can lead to the development of dementia, which is associated with decreased cognitive function. This study aimed to examine the impact of geriatric oral health (GOH) on the QoL of Korean seniors and the mediating effects of cognitive function. Methods: We used data from the seventh Korean Longitudinal Study of Aging conducted in 2018. In total, 4049 seniors were included in our study. We analyzed the impact of GOH on QoL according to 5 mediating domains of cognitive function and control variables. To examine each path of mediating effects, bootstrapping with 5000 iterations was performed with 95% confidence intervals. Results: Our findings revealed that good GOH had a positive effect on the QoL of seniors. Also, better GOH corresponded to a higher degree of cognitive function within all 5 domains: orientation, memory registration, attention/calculation, memory recall, and language and visuospatial ability. In addition, 3 domains of the 5 domains (attention/calculation, memory recall, and language and visuospatial ability) had significant mediating effects on the relationship between GOH and QoL. Conclusions: This study suggests that adequate management of GOH is crucial for promoting a better QoL and a high degree of cognitive function among seniors. To prevent cognitive impairment, such as dementia, future studies should take a more targeted approach by examining data according to each cognitive domain and various socio-demographic factors.

  • 한 사회/국가의 적정인구는 '그 사회/국가의 기술, 자본, 노동 등 생산요소의 선택 가능한 경로위에서 현재와 장래의 세대에 걸쳐 사회후생수준을 극대화하는 인구경로'로 정의할 수 있다. 따라서 인구의 적정규모 또는 적정증가율은 (i)사회후생함수와 (ii)생산함수가 주어진다고 할 때 (iii)한편으로는 국민소득의 처분과정이 출산력, 교육수준, 사망력 등 인구요인과 갖는 관계, 다른 한편으로는 소득의 처분과정에 따라 달라진 인구요인이 생산함수와 연계되는 과정, 즉 인구-경제 연관관계에 따라 다르게 된다. 이 정의에 의하면 적정인구경로는 주어진 생산함수와 인구-경제 연관관계하에서 사회후생함수를 극대화하는 동태적 최적화과정으로 도출할 수 있게 된다. 이 경우 적정인구경로는 사회후생함수, 생산함순 인구-경제연관관계를 나타내는 여러 파라메타들의 함수로 나타나게 되며 이들 파라메타에 대하여 우리나라의 향후 전망치를 대입하면 우리나라의 적정인구경로가 도출될 수 있는 것이다. 본 연구는 지금까지 경제학계의 논의를 이론적 배경으로 하여 사회후생함수, 생산함수, 인구-경제연관관계를 설정하고 각 파라메타에 대한 우리나라의 실증적 전망치를 대입하여 우리나라의 적정인구경로를 추정하였다. 그 결과 우리나라의 적정인구경로는 TFR=1.81 수준인 것으로 나타났는데 편탄력도외 크기로 보았을 때 적정수준에서 TFR의 변화에 가장 민감하게 영향을 주는 변수는 육아비, 자본소득배분율, 소비율, 시간선호(할인)율, 효용의 인구탄력도의 순으로 나타났다. 그리고 적정인구에 대한 인식이 사회경제계층별로 차이가 있을 수 있는데 본 연구를 위하여 시행된 설문조사에 의하면 육아비, 시간선호(할인)율, 효용의 인구탄력도가 계층별로 큰 차이가 있음이 나타났고 이러한 차이는 우리나라의 경우 기성세대보다는 신세대, 고학력자보다는 저 학력자의 적정인구경로가 낮을 것임을 시사하고 있다.타나는 메스꺼움이 문제로 지적되었으며 저 혈당현상은 큰 문제가 되지 않는 것으로 나타났다. 이 약은 인슐린 대용약물이 될 수 없으며 당뇨병성 케토산증의 치료에 사용할 수 없다. 또한 이 약물은 심한 신부전이 있거나 말기신장질환 환자에게 사용해서는 안 된다.u}M$ 농도에서도 비교적 안전한 화합물로 확인되었으며, 작용기전은 MITF 단백질을 조절함으로 활성을 나타내는 것으로 확인되었다.이 바람직할 것으로 생각된다. 얻었으며 두 군 사이에 임상적 결과의 차이는 없었다.건측 보다 10도의 굴곡 제한이 있었다. 결론: 자가 슬괵 건을 이용한 전방 십자 재건술 시, 경골 부의 고정 시 슬관절의 굴곡 각도 따른 슬관절의 전방 안정성에 차이는 없었으나, 신전 위에서 고정하는 것이 과도한 이식 건의 장력으로 인한 슬관절 굴곡 구축을 예방하는데 도움이 될 것으로 사료된다.라 증가할 것으로 추정되었으며 이에 대한 연근 추출물 경구 투여가 간 조직을 보호할 수 있는지를 확인하기 위해 분리한 혈청으로부터 ALT 함량을 측정한 결과 대조군에 비하여 유의한 감소를 나타내었다. 또한 연근 추출물이 혈청 내 지질 과산화물의 생성을 억제할 수 있다면 질병의 예방과 치료에 효과적일 것으로 추정할 수 있으므로 그 생성량을 측정하여 보았으나 대조군과의 차이가 나타나지 않았다. 이상의 결과들을 종합하여 보면 스트레스가 부하된 5일 동안 연근(蓮根) 추출물을 함께 투여한 결과 혈청 corticosterone 함량을 유의하게 감소시켰고 뇌 조직내 noradrenaline 함량을 증가시키는 경향을 나타내어 스트레스 해소에 도움이 될 수 있음을 시사하였다. 또한 혈청 내 ALT 함량을 유의하게 감소시켜 스트레스로 인해 발생하는 간 기능의 손상도 어느 정도 억제시키는 것을 확인할 수 있었는데 앞으로 연근(蓮根)의 이러한 작용에 대한 보다 자세한 연구들이 필요한 것으로 생각된다

  • This paper is to examine the effect of the receiver pays principle (RPP) on the calling price, social welfare and interconnection charge. A significant trouble with introducing this system in telecommunications pricing is the possibility that the receiving party may refuse to receive a call if the charge he has to bear is very high. We find the condition for no calls to be refused and show that the profit maximizing prices charged to the calling party and the receiving party must satisfy this condition. We demonstrate that the calling price under RPP must be lower than the price under the caller pays principle (CPP), that the profit of a firm will be increased under RPP, but that the consumer surplus will not necessarily be increased under RPP despite the lowered calling price. Also, we show that, if the demand function is linear, the reciprocal interconnection charge under RPP is higher than that under CPP.
