The purposes of establishing accreditation standards for the occupational therapy program are to assure the quality of the program and to assist in the development of the program. Accreditation serves the public as accredited programs modify their requirements to reflect changes in knowledge and practice generally accepted in the field. To students, accreditation provides an assurance that the educational activities of an accredited program have been found to be satisfactory, and therefore meet the needs of students. Also it assists in the transfer of credits between institutions, or in the admission of students to advanced degrees through the general acceptance of credits among accredited institutions when the performance of the students has been satisfactory and the credits to be transferred are appropriate to the receiving institution. The occupational therapy programs benefit from accreditation through the stimulus provided for self-evaluation and self-directed program improvement and strengthening of program self-evaluation by the review and counsel provided through the accrediting agency. At the same time, this process enhances the reputation of an accredited program because of public regard for accreditation. Lastly, the profession of occupational therapy can be strengthened by contributing to the unity of the professions in an activity directed at improving professional preparation and professional practice.

이택영,김택훈,최흥식 대한작업치료학회 2003 대한작업치료학회지 Vol.11 No.1

Objectives : This study evaluated norms for fine motor dexterity skills on kindergarten and elementary school children. Method : Participants were recruited from five kindergartens and two elementary schools in Seosan area. The sample consisted of 160 healthy students ranging in age from five to eight years. The Grooved Pegboard Test (GPT) was utilized to investigate fine motor dexterity. Results : The GPT showed statistically significant differences in hand dominance based on the findings that the scores of nondominant hands were substantially lower than those of dominant hands (p<0.05). The GPT showed significant age group differences in which 8 year old group demonstrated substantially higher scores than those of all other younger age groups (p<0.05). The results indicated a positive relationship between age and GPT scores. Conclusion : The results of this study support the results of previous studies that compared hand function between healthy children and abnormal children. These data will provide standard value of GPT for occupational therapists.

The purpose of this study is to first to evaluate the function of the involved upper extremity of adult hemiplegia in relation to the hand dexterity with the uninvolved hand by using Manual Function Test(MFT) to measure the function of the involved upper extremity and Grooved Peg Board Test to assessment the hand dexterity with the uninvolved hand. Second to evaluate the hand dexterity with the uninvolved hand of adult hemiplegia in relation to activities of daily living(ADL) by using Functional Independence Measure(FIM) to measure the ADL. The subjects in this study were 21 stroke patients who were admitted for intensive treatment at Department of Rehabilitation in Asan Medical Center from September to November, 1998. Data were analyze for wilcoxon signed ranks test and Spearman correlation coefficients using SPSS/PC+ program. The results of this study are : 1) Statistically MFT score at admission showed significant correlation with MFT score at discharge (p < 0.01). 2) Statistically the hand dexterity with the uninvolved hand at admission showed si-gnificant correlation with the hand dexterity with the uninvolved hand at discharge(p< 0.01). 3) The function of the involved upper extremity and the hand dexterity with the un-involved hand are poorly related variables in stroke patients(p < 0.01). 4) The function of the involved upper extremity and independence in ADL are poorly related variables in stroke patients(p < 0.01). 5) The hand dexterity with the uninvolved hand and independence in ADL are poorly related variables in stroke patients(p < 0.01). 6) In the relationships between FIM score at admission and FIM score at discharge; there were no significant differences(p < 0.01). It was difficult to compare the measured hand dexterity with the uninvolved hand in stroke patients as well as to assess the hand dexterity with the same side hand in normal, for it is in the variation between the current data used for this study and the standard data obtained from Lafayatte Instrument Company. The activities of daily liv-ing of the hemiplegic patient are largely dependent on their uninvolved hand which is thought to be vital for the rehabilitation of the hemiplegic patients. Therefore, occupa- tional therapy program in stroke patients should include improving skills of uninvolved hand.

이택영,정민예,정보인,유은영,장세진,남은우 대한작업치료학회 2009 대한작업치료학회지 Vol.17 No.1

목적 : 연구의 목적은 우리나라 노인들의 문화와 정서에 적합한 활동척도를 개발하여 남녀 노인의 활동 수준과 의미 있는 활동을 비교하고, 노인의 삶의 질에 영향을 미치는 요인들의 관련성을 규명하였다. 연구방법 : 연구의 대상은 60세 이상 남자 노인 199명, 여자 노인 258명으로 총 457명이 참여하였으며, 노인생활만족척도를 사용하여 노인의 삶의 질을 평가하였다. 또한 노인의 활동수준은 평가를 위해 한국판 활동척도를 개발하여 연구에 이용하였다. 결과 : 노인의 수행 활동을 성별로 비교하여 볼 때 여자 노인은 수단적 일상생활을 남자 노인은 고강도 신체활동을 더 많이 하였으며, 노인의 활동과 삶의 질과의 상관관계를 통하여 남, 여, 전체 노인에서 수단적 일상생활, 저강도 신체활동, 고강도 신체활동, 사회활동에 많이 참여할수록 삶의 질은 높았다. 최종적으로 위계적 다중선형회귀분석을 통하여 노인의 삶의 질에 영향을 주는 요인으로는 전체 노인의 경우 연령, 건강상태, 생활수준, 노후설계 준비기간, 사회활동이, 남자 노인의 경우 건강상태, 배우자 유무, 생활수준, 노후설계 준비기간이 삶의 질을 예측할 수 있는 요인으로 작용하였으며, 여자 노인의 경우 연령, 건강상태, 생활수준, 노후 설계 준비기간, 사회활동이 삶의 질을 예측할 수 있는 요인으로 작용하였다. 결론 : 연구 결과를 토대로 남녀 노인에 적합한 성별에 따른 차별화된 활동을 개발하고 1차, 2차, 3차 예방 사업에 사회활동 요소를 포함하여야 할 것이다. 향후 전국 조사를 통하여 우리나라 노인들을 대상으로 활동 수준과 삶의 질과의 관련성을 규명할 수 있는 다양한 연구들이 수행되어야 할 것이며, 작업치료적 관점에서 장애 노인을 대상으로한 활동의 변화와 삶의 질에 대한 연구가 진행되어야 할 것을 제언한다. Objective : The purposes of this study were as follows: (1) to investigate the activities that Korean elderly people usually participate in, (2) to compare the features of activities between male and female elderly per-sons, and (3) to clarify the factors that influence the quality of life in the elderly based on the Model of Human Occupation(MOHO). Methods : The participants were 199 male and 258 female elderly subjects aged 60 and over. Their quality of life was measured using the Older Adult Life Satisfaction Scale devised by Sung-Jae Choi, and their level of activities was measured using the Activity Check List, which was adapted for Korean culture and environment. Results : In general, the quality of life was higher in male elderly subjects than in female elderly ones, and it was also affected by age, presence of spouse, health status, level of education, present companion, financial status, and preparation period of retirement. The main activities were IADL in female elderly subjects and high-demand physical activities in male elderly subjects. As the elderly participate in more activities such as IADL, low and high-demanding physical activities, and social activities, the quality of life was higher in both groups according to the correlations between the quality of life and each activity. The factors that could pre-dict the quality of life based on hierarchical multiple linear regression analyses were as follows: (1) age, health status, economic status, preparation period for retirement, and social activities in both groups; (2) health status, presence of spouse, economic status, and preparation period for retirement in male elderly subjects; and (3) age, health status, economic status, preparation period for retirement, and social activities in female elderly subjects. Conclusion : The significance of this study could be placed on the facts that activity levels of Korean elderly persons were investigated and that their quality of life was evaluated according to the activities. In the fu-ture, various studies investigating the relationships between activity levels and quality of life are expected for the Korean elderly nation-wide using a larger number of participants.

소아에서 발생한 전신성 모세혈관 누출 증후군(Systemic Capillary Leak Syndrome) 1례

이택영,정유미,강희경,하일수,정해일,최용,Lee, Taeg Young,Chung, Yoo Mi,Kang, Hee Gyung,Ha, Il Soo,Cheong, Hae Il,Choi, Yong 대한소아청소년과학회 2002 Clinical and Experimental Pediatrics (CEP) Vol.45 No.10

Systemic capillary leak syndrome(SCLS) is a rare disorder of unknown etiology, which is characterized by recurrent attacks of hypotension, hemoconcentration, and hypoalbuminemia. Urinary or enteric loss of protein is not demonstrated. It is often associated with monoclonal gammopathy, but does not manifest multiple myeloma. Since Clarkson et al. described the first case in a 34-year-old woman, about 50 cases have been reported in the literature. However, most of the cases were of adult age, and the mean age of onset in the reported cases was 42.6 years. In literature review, we could refer only one pediatric case of SCLC by Foeldvari et al. in 1995. We report another pediatric case of SCLS.

With the aim of promoting the use of metropolitan railways, the present research developed a mode choice model for evaluating its competitiveness against passenger cars. A case study was carried out with Gyeongeui and Joongang line, and the area of interest was the direct operating railway between Ilsan and Guri station where the two lines intersect. The mode choice model was a disaggregate behavior model which used Stated Preference (SP) survey data, and the plot of competition was between private passenger cars and express trains. As a result, the mode choice model was established, and this model was used to analyze characteristics of passengers' time value and elasticity. It was shown that reducing travel time is more efficient than reducing travel cost when it comes to operating express trains in metropolitan railways. Therefore, policies designed for activating the use of metropolitan railways should expand direct operating service of individual lines and run more express trains in order to minimize transfer and in-vehicle time.

리튬이온전지 부극용 GIC의 전도성에 미치는 SnCl₂ 영향

이택영,이철태,김현중,송연호,엄의흠 한국공업화학회 2001 한국공업화학회 연구논문 초록집 Vol.2001 No.-

리튬이온전지의 부극활물질로서 탄소전극을 사용할 때에 리튬금속에 비해 단점으로 지적되는 탄소 전극의 에너지밀도를 높이며 또한 충ㆍ방전시의 리툼의 삽입ㆍ탈삽입이 용이하도록 하기 위한 연구들이 시도되고 있다. 탄소재료의 경우 이론적인 최대 방전용량은 372mAh/g이 되며 결정성 탄소 재료인 흑연의 경우에도 이와 같은 방전용량을 가진다. 그러나 실제 충ㆍ방전이 반복됨에 따라 용량감소가 생 기게 되는데 이러한 현상은 리튬이 흑연 내부로 삽입될때에 층간거리(d₀₀₂)가 3.35Å에서 3.70Å으로 팽창하고 탈삽입시에 다시 3.35Å으로 수축되는 현상의 반복으로 충ㆍ방전 반응이 계속 진행됨에 따라 흑연의 층상구조가 무너지게 되어 용량이 감소하고 수명이 저하되는 원인이 된다. 이처럼 리튬이 삽입ㆍ탈삽입되는 과정은 흑연이 가지는 층간거리와 깊은 관계를 가지게 되므로 본 연구에서는 흑연의 층간에 Sn원자를 삽입시켜 층간 거리를 일정하게 유지함으로서 리튬의 삽입ㆍ탈삽입 거동에 있어서 발생되는 확산저항을 감소시키며 보다 많은 리튬의 저장공간을 안정하게 확보하여 전지의 용량 및 수명을 향상시키고자 하였다. 따라서 본 연구에서는 천연 흑연을 열처리 한 후 다양한 농도의 SnCl₂용액과 교반 시키고 이것을 진공반응기에서 다양한 온도로 반응시켜 Sn원자를 흑연의 층상구조에 삽입시켜 전도성을 가진 Sn-GIC를 합성하였다. 그리고 그 물질을 리튬이온전지의 부극활물질로 적용하고 정극으로 리튬금속을 사용하여 cell을 제작하였으며 이의 전기 화학적 거동을 조사하여 Sn-GIC가 리튬이온전지의 부극으로 사용될때의 특성을 조사하고 리튬이온전지용 부극활물질로의 사용 가능성을 확인 하고자 하였다.
