Purpose : The purpose of this study was to investigate functional disability for the elderly in rural Korea and to identify influencing factors of functional disability. Methods : The data were collected for 76 community-dwelling elderly in rural area and above 65 years. We assessed cognitive function, functional disability, depression using LACLS, WHODAS 2.0, SGDS-K. Data were analyzed using descriptive statistics for general characteristics of subjects, Spearman’s correlation among LACLS, SGDS-K, WHODAS 2.0, age, educational levels. And multiple regression was used to find influencing factors of functional disability. Results : As a result of this study, we identified that WHODAS 2.0 total score was 50.59, summary score was 9.94 and functional disability of the elderly in rural area is in the 70th percentile. The highest level of disability occurred in areas related to ‘life activities (household)’, ‘participation in society’ and the lowest level of disability occured in areas of ‘self-care’, ‘getting along with people’. Functional disability was significantly correlated with age (r=.398), cognitive function (r=-.547), depression (r=-.563) but not educational levels (r=-.215). Finally, we confirmed that depression (β=.371), cognitive function (β=-.263), widowed status (β=.303), age (β=.272), non-participation of community program (β=.165) was significantly influencing factors of functional disability and the explanatory power of these factors was 52.80 %. Conclusion : This study revealed important factors of functional disability. Therefore, we need to consider these factors when we developed program related to health for the elderly (aged > 65 years) in rural Korea. Further, we need to standardize WHODAS 2.0 in order to enhance its applicability in clinical practices.

We investigated characteristics of an active micromixer using DC-biased AC Electroosmosis by varying parameters like DC biasing voltage, AC frequency, AC voltage and etc. When applying 25V<SUB>pp</SUB>, 2.0 V<SUB>DC</SUB>, 100㎑ sine signal to amixer with a single electrode pair, we found that a mixing index became 80%. The mixing index slight increases with decreasing AC frequency. In contrast, the mixing index significantly increased with increasing AC voltage or DC-biased voltage. Also, we confirmed that the mixing index decreases as the flow rate increases in the microchannel. Finally, wewere able to increase the mixing index up to 90% by introducing alternating vortices in direction with three electrode pairs.

목적 : 혈관 조영 시술시 표준선량과 저선량 프로토콜의 확대율 변화에 따른 화질과 선량을 비교하여 임상적 지표 활용을 목적으로 한다. 재료 및 방법 : 본원의 SIEMENS 장비와 NEMA팬텀, Unfors Xi meter를 사용하였다. 표준선량과 저선량 프로토콜을 사용하였을 때 영상 확대 변화를 주어 30초간 총 5번의 누적선량을 측정후 평균값을 비교하였다. 또한, 두 프로토콜 간 평균 선량 차이에 대한 통계적 유의성을 검증하기 위해 독립표본 t-검정(SPSS t-test)을 하였다. 확대율에 따른 화질 비교를 위하여 공간분해능, 저 대조도 분해능, 와이어분해능을 측정하였다. 결과 : 확대율 변화에 따른 표준선량과 저선량의 누적선량을 비교한 결과, 저선량이 표준선량에 비해 48cm 27.88%, 42cm 39.92%, 32cm 29.68%, 28cm 38.72%, 16cm 11.71%, 11cm 0.83%의 선량 감소율을 보였다. p-value값은 11cm를 제외한 48cm, 42cm, 32cm, 22cm, 16ccm에서 p<0.001로 통계적으로 유의성이 높았다. 화질 변화는 48cm에서의 화질 차이는 없었다. 42cm, 32cm, 22cm에서는 공간 분해능만 저하되었다. 16cm와 11cm의 화질 차이는 없었다. 결론 : 저선량은 표준선량 프로토콜에 비해 48cm, 42cm, 32cm, 22cm에서 평균 34.05±6.14%의 선량 감소율을 나타내는 것에 비해서 16cm는 11.71%로 낮게 나타났고, 11cm에서는 0.83% 감소로 거의 비슷하게 나타났다. 하지만 선량 감소율에 비해 NEMA Phantom을 이용한 화질 비교에서는 42cm, 32cm, 22cm에서만 공간분해능 저하가 나타나고 다른 확대율에서는 화질 변화가 없었다. 결과적으로 20cm 두께의 NEMA Phantom에서의 저선량 프로토콜은 선량 감소율에 비해서 화질의 차이는 표준선량과 크지 않다고 볼 수 있다. Purpose : This study aims to compare the image quality and dose in accordance with the changes of magnification power of standard dose and low dose protocol in angiography to utilize it as clinical index. Matrials and method : This study used SIEMENS equipment, NEMA phantom, Unfors Xi meter. The study conducted comparison on average value after examining accumulated dose during 30 seconds for 5 times by giving variation to magnification power of image when using standard and low dose protocol. An independent sample t-test was performed to verify the statistical significance of the mean dose difference between the two protocols. To compare the image quality in accordance with magnification power, the study measured spatial resolution, low contrast resolution, wire resolution. Result : As the result of comparing accumulated amount of dose, the low dose had decrease rate of dose compared to standard dose(48cm 27.88%, 42cm 39.92%, 32cm 29.68%, 28cm 38.72%, 16cm 11.71%, 11cm 0.83%). Excluding 11cm, all variables were statistically very significant as p<0.001. As for the image quality, there was no image quality difference in 48cm. spatial resolution showed decrease in 42cm, 32cm and 22cm. There was no image quality difference in 16cm and 11cm. Conclusion : When low dose showed average decrease rate of dose about 34.05±6.14% in 48cm, 42cm, 32cm, 22cm compared to standard dose protocol, 16cm had decrease rate as low as 11.71% and 11cm had decrease rate of 0.83% which was similar. However, compared to decrease rate of dose, in image quality comparison using NEMA Phantom, only 42cm, 32cm and 22cm had spatial resolution, and other magnification power did not show difference in image quality. In conclusion, the low dose protocol in NEMA Phantom with 20cm thickness did not have significant difference in image quality with standard dose compared to decrease rate of dose.

일반논문 : 대한제국 시기 한인의 일본육사 입교와 졸업 후 동향

박단비 ( Dan Bi Park ) 단국사학회 2015 史學志 Vol.50 No.-

대한제국은 1898년 陸軍武官學校를 설립하여 군대의 근대화와 함께군사 간부를 양성하였다. 한인청년들은 무관학교 설립 이전에도 군사 훈련을 받았다. 이들은 日本陸軍士官學校에 입학하여 교육을 받게 되었다. 당시 일본육사는 일본의 근대사를 움직여온 인물들을 양성해 낸 주요 교육기관이었다. 한인 청년들은 일본유학과 대한제국 군대해산의 영향으로 일본육사에 입교하게 되었다. 특히 대한제국 군대가 해산이 된 결과 대한제국 육군 무관학교에 재학 중이던 생도들은 일본군에 위탁이 되었다. 이후 선발시험을 거쳐 무관학교 생도 42명이 일본으로 파견되었고, 이들 중 14명이 일본육사로 진학하였다. 한인 청년들은 임관이 된 이후 귀국하여 대한제국의 교육기관에 진출하였다. 대다수 일본육사 출신자들은 일본에 협력하며 군직을 이어갔다. 이들은 1907년 대한제국 군대해산을 주도하고 의병을 진압하기도 하였다. 대부분의 일본육사 출신자들이 일본의 회유책을 따랐으나, 일부는 이를 거부하고 군직을 떠나 독립운동의 길을 나섰다. 일본육사 출신들의 영향력은 대한제국 시기 뿐만이 아니라 해방 이후에도 계속되었다. This paper aims to study the trends after Korean young men graduated the Imperial Japanese Army Academy in the age of the Korean Empire. In 1898, the Korean Empire founded a military officer school(陸軍武官學校) to modernize the army and train military leaders. Korean young men received military training even before the military officer school was founded. They entered the Imperial Japanese Army Academy(日本陸軍士官學校) and received training. In those days, the Imperial Japanese Army Academy was a major educational institution to train figures who led Japanese modern history. The admission of Korean young men into the Imperial Japanese Army Academy was influenced by studying in Japan and the army disbandment of the Korean Empire. After that, a lot of Korean young men received education in Japan through the intercession of intellectuals from the enlightenment party. Each of them entered educational institutions such as Gyeongeungeuisook University(Keio University), Hosan School, gyododan(Military Training School) and Donginsa. In early days, they duplicated military education completion in Imperial Japanese Army Academy, Gyododan and Hosan School. Another motive for the admission into the Imperial Japanese Army Academy was the army disbandment of the Korean Empire. Japan set to work to reduce its troops first to disperse the army of the Korean Empire by reason of unnecessary waste of armaments. The army disbandment plan was carried out under the title of Armament Reduction Project. Emperor Sunjong was coerced by Japan into declaring an ordinance to disband the army and entrust military officer training. As the result, the cadets in military schools of the Korean Empire were entrusted to the Japanese army. After that, 42 cadets who passed the selection examination, were sent to Japan and 14 of them entered the Imperial Japanese Army Academy. There was a process for the entrance of Korean young men to the Imperial Japanese Army Academy. This process varied depending on the period. In early days, they learned language and common studies in Gyeongeungeuisook University and then received basic military training in Seongseong School. However after Gyeongeungeuisook University disappeared, they got straight into Seongseong School. The institution for providing basic military training also gradually changed into Japanese Central Army School for Children from Seongseong School. Imperial Japanese Army Academy’s education system was modeled on the Western system. In the beginning, it was based on the French system, but increasingly changed into the German-style system. Korean young men first entered the school as 8th trainees when its education system changed into the German style. Educational contents that they learned in the school, were not highly different from those taught in the preliminary educational institution. They received specific education about military science, foreign languages. The training period was nearly a year to two years. The trainees could be commissioned as officers, after completing probational officer duties for a certain period of time along with military training. After commission, Korean young men returned to Korea and worked in educational institutions of the Korean Empire. This was implemented at the suggestion of Min, Young-hwan to Emperor Gojong. After being assigned to military schools as instructors, they were promoted to principals. The graduates from the Imperial Japanese Army Academy were even placed in Yeonseong School and Yoonyeon School that were newly established, according to the military system reformed later on. As all the three major military training institutions were occupied by them, Japanese education began to be introduced. Korean young men started their first duties in military training institutions of the Korean Empire, after graduating from the Imperial Japanese Army Academy. A majority of the graduates from the Imperial Japanese Army Academy continued the military profession, cooperating with the Japanese government. In 1907, they took the lead in dispersing the troops of the Korean Empire and repressed the army raised in the cause of justice. Most graduates from the Imperial Japanese Army Academy followed the conciliatory policy of Japan, but some of them refused this and left the military profession. Korean young men received equal education in the Imperial Japanese Army Academy. Although they showed conflicting aspects right after graduation, their influence lasted not only during the era of Korean Empire but also after liberation.
