Objectives:Recent studies have raised the possibility that nerve growth factor(NGF) is abnormally regulated in the central nervous system(CNS) of animal models with alcohol dependence. The possible alteration of NGF by prolonged alcohol intake may play an important role in alcohol-induced neurotoxicity. Carbohydrate-deficient transferrin(CDT) is regarded as a reliable biological marker of alcohol dependence. The goal of this study was to estimate the changes of %CDT and serum NGF level according to the duration of alcohol abstinence, and to identify whether %CDT level is associated with the serum NGF level in the patients with alcohol dependence. Methods:The subjects were 24 patients with alcohol dependence. We used the Axis-Shield ASA to measure the %CDT level and the enzyme-linked immunosorbent assay(ELISA) to measure the serum NGF level. %CDT and NGF levels were measured immediately after the admission and at 2 weeks after the admission. Results:Decreased %CDT were observed during the period of 2 weeks after the admission. NGF level was not significantly different after 2 weeks. The NGF levels were not correlated with %CDT. The possibility of %CDT as a predictor of alcohol-induced neurotoxicity was not confirmed. Conclusion:Serum NGF levels is not a reliable indicator of abstinence state in the patients with alcohol dependence. Further studies are needed to evaluate the relation between two indicators in regard to hematological and neurological changes in alcohol dependence.

The importance of LCC analysis has been enlarged. Also, it would be necessary to computerize LCC analysis for accurate and logical analysis of LCC. In other papers, they showed LCC analysis model but the study of database development which could be applied in LCC analysis have been undeveloped. This study showing the development of common database for the LCC analysis computerization inquires into cost breakdown structure by previous researches. Also, it makes cost breakdown structure for deriving LCC cost item. As a result, the standard of LCC analysis computerization by developing LCC DB of cost breakdown structure would be shown.

In currency crisis(IMF relief loan), the construction industry has prepared a foundation for existence by taking such desperate countermeasure as reducing a lot of construction companies and readjusting the their structure. Even though a number of employee of construction industry came to a million in 1996, it reduced to 980 thousand in 1997 and 710 thousand in 1998. After 1998, there was the trend about reducing a number of employee every year. The final goals of this study have inquired into the current situation of manpower supply and demand per region, compared and analyzed the circumstance of manpower supply and demand, and utilized references in decision-making between construction companies and students.

A wearable electrodiagram(ECG) monitoring system is a widely used non-invasive diagnostic tool for ambulatory patients who may be at risk from latent life-threatening cardiac abnormalities. In this paper. we have a portable ECG monitoring system with conductive fiber characterized by the small-size and the low power consumption. The system consists of conductive fibers, one-chip microcontroller, ECG preprocessing circuit, and monitoring software to record and analyze in PC. ECG preprocessing circuit is made of pre-amplifier with gain of 10, band-pass filter with bandwidth of 0.5-120% and 2.5V offset circuit for A/D conversion. ECG signals obtained by sensor are corrupted by noises such as a baseline wandering, 60Hz power noise and interference noise by body movement. For cancellation of noises in signals obtained by conductive fiber, we used the wavelet decomposition of wavelet transforms in MATLAB toolbox.

전국 일반계 고등학교 재학생의 작업치료 인식도에 관한 연구: 2021년 온라인 설문조사에 근거하여

정세희,백소현,전찬민,최정은,이지수,장우혁 대한작업치료학회 2022 대한작업치료학회지 Vol.30 No.3

목적:본 연구는 전국 일반계 고등학교 재학생 1, 2, 3학년들을 대상으로 작업치료 인식도 조사를 실시하여 학년별 작업치료 인식도를 확인하고, 그에 따른 학과 탐색의 시기를 파악하는 데에 목적이 있다. 이를 통해, 작업치료의 인식도를 향상시키도록 하는 효율적인 홍보방안을 제시하고자 한다. 연구방법:전국 17개 지역의 일반계 고등학생들을 대상으로 2021년 11월 22일부터 12월 5일까지 알게 된 경로, 최소한의 교육과정, 국가고시 필수 여부, 대상자의 연령대, 업무 범위, 취업처와 같은 작업치료 인식도와 작업치료(학)과 지원 및 홍보 방법에 대한 질의와 응답으로 구성된 N사의 온라인 설문지 공유를 통해 실시하였다. 수집된 설문지 총 860부 중 부적절한 응답 153부를 제외한 707부를 분석하였다. 수집된 자료 처리 및 분석은 기술통계량을 이용한 빈도분석을 실시하였다. 결과:고등학생의 작업치료 인식의 수준은 48.9%로 나타났다. ‘작업치료 대상자의 연령대’를 학년별로 구분하여 분석한 결과, ‘모르겠다’를 선택한 비율이 1학년 177명(32.2%), 2학년 157명(30.3%), 3학년 84명(23.6%)으로 학년이 높아질수록 낮아지는 것으로 확인되었으며 학년별로 분석한 다른 작업치료 인식도 항목 또한 같은 결과를 보였다. 고등학생이 희망하는 학과 홍보 방법으로는 ‘Social Network Service(SNS)홍보 게시물’이 26.2%로 가장 높게 나타났다. 결론:일반계 고등학생은 학년이 높아질수록 작업치료 인식도가 높아졌다. 이는 고등학생들이 진로를 위한 학과 탐색을 통해 높아지는 것으로 추론할 수 있으며, 충분한 탐색의 시간을 제공하기 위해 고등학생이 희망하는 학과 홍보 방법인‘SNS 홍보 게시물’을 활용하면 작업치료 인식개선 등의 효과적일 것이라 사료된다.
