Sn-3.5Ag 솔더를 이용한 플립칩의 열 성능 분석

이택영,박덕용 한밭대학교 2003 한밭대학교 논문집 Vol.20 No.-

Thermal performance of flip chip bonding with Sn-3.5Ag solder ball was studied. The temperature distribution was measured with IR(InfraRed) camera of 25 um resolution. The measurement shows that most of the samples had much higher maximum temperature than average temperature. With central heater and 2.5(W), the difference between maximum and average temperature is over 80℃. The distribution was influenced by the location of heater, the distance from heater to flip chip bonding, and the passivation opening of solder bumps. To reduce the maximum temperature, the bigger passivation opening, the smaller chip size, and the closer location of heater to flip chip bumps are preferrable.

Activities of daily living (ADL) and instrumental activities of daily living (I-ADL) are tasks of self-care, functional mobility, functional communication, home management, and community living that enable an individual to achieve personal independence. The purpose of this study were to investigate the effect of factors on ADL in stroke patients and to identify the relationship between the function of upper extremities and ability of ADL. Thirty-one stroke patients participated in this study. The results of this study were as follows: 1) There were significant functional gains between admission and discharge on the MFT score, dexterity, and the motor FIM(p<0.01). 2) There were moderate correlation between MFT score of the non-affected side and motor FIM score at discharge(r=0.499, p<0.01) and high negative correlation between dexterity of non-affected hand and motor FIM score at discharge(r=-0.704, p<0.01). 3) There was a significant difference on motor FIM score among academic background groups (p<0.01). 4) There was no significant difference on motor FIM score among caregiver groups (p<0.01). 5) Four factors were found. one factor comprised dexterity of non-affected hand at admission and discharge and duration of treatment. Two factor comprised MFT of non-affected side at admission and discharge and academic background. Three factor comprised MFT of affected side at admission and discharge and caregiver. Four factor comprised sex and affected side.

The first national occupational therapy licensing examination was administered by the National Institute of Health in 1965. In 1998, National Health Personnel Licensing Examination Board assumed responsibilities for the development, administration, and implementation of the licensing process based on current and valid standards for occupational therapy practice. The purpose of awarding license is to identify for the public those persons who have demonstrated both the knowledge and the skills necessary to provide occupational therapy service. As an effort to develop, maintain, and defend the content validity of practice-based occupational therapy licensing examination, National Health Personnel Licensing Examination Board sponsored and authorized the occupational therapy practice analysis study in 2000. Based on the occupational therapy practice analysis study, Minimum Standards for the Education of Occupational Therapists By World Federation of Occupational Therapists, and The National Occupational Therapy Practice Analysis in the USA, this article points out several problems concerning the existing national occupational therapy licensing examination and suggests the alternatives that reflect current professional practice.

본 연구는 현재 제기되고 있는 작업치료사 인력의 과잉공급과 이에 따른 문제점을 지적하고 향후 발전적인 해결방안을 제시하고자 한다. 현 작업치료 교육기관과 임상현장에서의 문제점은 작업치료사 인력의 과잉공급과 작업치료 전공 교수요원의 부족, 작업치료의 의료보험수가 청구의 문제 등을 지적할 수 있다. 문제들을 해소하기 위한 개선 방안으로는 작업치료(학)과의 신설 및 증원에 있어 설치 기준안에 의한 승인, 작업치료실 개설 및 작업치료사의 고용 의무화, 작업치료사의 다양한 활로 개척, 작업치료 전공 교수의 체계적인 육성, 작업치료 의료수가 처방 권한의 확대와 다양한 치료수가 개발이 절실히 필요하다. 앞에서 제시된 문제를 해결하기 위해서는 임상의 작업치료사와 학생, 교수 모두가 노력해야 하며 작업치료에 대한 적극적인 홍보와 작업치료에 대한 만족도, 기여도, 요구도 등의 기초 자료를 위한 연구가 활발히 진행되어 통계적인 자료를 제시하여야 한다. This article aims to point out the controversial issue of deteriorating quality of occupational therapy service due to oversupply of manpower and to emphasize the importance of training the qualified future-oriented occupational therapists to deal with the rapidly changing healthcare delivery system. The majority of the Korean occupational therapy society is currently concerned about oversupply of manpower, shortage of qualified faculty, and underestimated occupational therapy service fee. In order to cope with this challenging situations, first, accreditation process for occupational therapy education program should be established, second, the obligatory law for setting up occupational therapy clinics and employing occupational therapists should be enforced, third, various areas should be explored, fourth, establishment of master and doctoral programs in the field of occupational therapy, fifth, prescription for occupational therapy should be open to all physicians, sixth, occupational therapy areas that can be reimbursed should be extended. As an effort to make these happen, clinicians, students, and faculty members should be more proactive in promoting occupational therapy and should be focusing on research that investigates the effects of occupational therapy. Through these efforts, the profession of occupational therapy in Korea will be strengthened by contributing to the unity of the professions in an activity directed at improving professional preparation and professional practice.

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.

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.

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.

이택영,오재근,김혜영,이규성,김문희 대한작업치료학회 1999 대한작업치료학회지 Vol.7 No.1

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.
