권찬미, 이동주, 엄성용 서울여자대학교 컴퓨터과학연구소 2017 정보기술논문지 Vol.15 No.-

In this paper, we propose an automatic order system for restaurant customers, which utilizes QR code and provides multilingual menu and currency conversion. The system consists of 2 main parts : application for customers, web and application for restaurant managers/owners. The main functions of the system are described with captured screens in this paper. Customers use the smart phone application and QR code tag attached each table to make orders. The multilingual menu and various currency feature help the foreign customers to make orders easily. The orders made by customers are automatically displayed in the smart phone or tablet installed in the cashier count and kitchen. The orders can be managed using web based system. 본 논문에서는 최근 빠르게 도입되는 무인 주문 서비스를 적용하여 다양한 식당과 국내외 소비자를 대상으로 개발된 QR 코드를 이용한 <다국어 간편 주문 시스템>에 대해 설명한다. 개발된 시스템 ‘QRans Order’는 식당 고객용 스마트폰 어플리케이션과 식당 운영자용 관리자 웹 및 스마트폰 어플리케이션으로 구성되어 있다. 본 논문에서는 개발된 시스템의 주요 기능을 화면 구성과 함께 설명한다. 시스템 구현 결과, 식당 고객용 스마트폰 어플 리케이션은 테이블마다 마련된 QR 코드를 이용하기 때문에 직원을 부르지 않더라도 앉은 자리에서 간편하게 음식을 주문할 수 있다. 또한, 다국어 기능을 통해 외국인 고객들도 간편하게 메뉴를 보며 주문할 수 있으며 선택한 언어에 따라 환산된 가격 정보도 알 수 있다. 식당 운영자용 관리자 웹 및 어플리케이션에서는 주문이 들어올 때마다 즉각적으로 주문 내역을 확인할 수 있으며, 식당 정보 및 메뉴 관리, 매출 관리 등의 업무를 체계적으로 관리할 수 있다.

수계 환경 오염이 어류에 미치는 영향을 조사하기 위해, 여러 종류의 어류(풀망둑 Acanthogobius hasta; 조피볼락, Sebastes schlegeli;동사리, Odontobutis platicephala;송사리, Oryzias latipes)에서 중금속 오염에 민감하게 반응하는 metallothionein(MT) 유전자를 polymerase chain reaction(PCR)을 이용하여 증폭하였고, 이들의 염기서열을 분석하였다. 조사한 대다수의 어류에서 MT 유전자를 특이적으로 증폭할 수 있었지만, 송사리의 경우 비특이적으로 증폭된 band도 있었다. 본 논문에서는 환경오염의 실험동물로 쓰일 수 있는 종을 중심으로 MT유전자를 증폭하였고 모든 어종에서 MT 유전자의 증폭이 이루어지지 않았으나, 다양한 목에서 같은 conserved primer로 MT유전자가 증폭될 수 있음을 보여 주었다. To investigate the effect of heavymetal contamination in aquatic environments, we amplified and sequenced the metallothionein (MT) gene, a sensitive biomarker, in some fishes. In most of the species tested (medaka, Oryzias latipes; javeline goby, Acanthogobius hasta; black rockfish, Sebastes schlegeli), we cloned the MT gene with a single band, but in a few cases (e.g., medaka), it was difficult to get the specific band for the MT gene. The fish MT gene was isolated with emphasis on several fish species that are candidates for environmental toxicology testing, but in a few cases, it was not successful. However, the PCR primers for this fish-specific MT gene worked properly even among fishes of different phylogenetic orders, although it did not always specifically amplify the MT gene.

Objective : Serum uric acid has now been identified as a marker for a number of metabolic and hemodynamic abnormalities. The aim of this study is to evaluate risk factors which influence hyperuricemia in the citizens of Asan. Method : The study design was cross-sectional and research subjects were 1086 citizens of Asan. General characteristics, cigarette smoking, alcohol consumption, and past history were obtained by interview using a structural questionnaire. Also, we measured height, weight and blood pressure, and serum uric acid of the subjects. Results : The mean serum uric acid level was 5.27 ㎎/㎗ in men and 4.01 ㎎/㎗, in women, In the multiple logistic regression analysis, statically significant risk factors of hyperuhcemia were gender, body mass index, blood lead concentration, and serum creatinine. Conclusion : Our results suggest that gender, body mass index, blood lead concentration, and serum creatinine might be the most important risk factors of hyperurcemia. Education program as well as routine check-up for serum uric acid was highly recommended for the effective prevention of hyperuricemia.

The purpose of this study was to investigate effect of aerobic exercise on ability of exercise performance in high school girls. The subjects of this study were 14 students in Y girls' high school(3rd grades). They were divided into two groups: 7 for an experimental group and 7 for a comparative group. The former was assigned to take a jogging for 16 weeks. The results were as follows; HR in the ability of exercise performance showed a significant decrease(F=4.52, P<.01). VO2max showed a significant increase(F=28.68, P<.001). VEmax showed a significant increase(F=3.48, p<.05). AT also showed a significant increase(F=30.57, p<.001). However no significant change was found in VE. From the above result, we can see that continuous jogging of high school girls has a significant effect on the increase in the ability of exercise performance. Jogging has just a little effect on body composition and blood component though significant difference was not found in them.

연구목적 : 최근 기능적 영상진단의 발전은 치매 환자의 진단에 많은 도움을 주고 있으며 이중 단일광자방출전산화단층촬영(SPECT ; single photon emission computed tomography)은 알쯔하이머 병의 특징적인 양측 두정측두엽의 혈류 감소를 보이므로 알쯔하이머 병의 진단에 많이 사용되어지고 있다. 본 연구는 알쯔하이머병의 SPECT 소견을 분석함으로써 알쯔하이머병의 진단에 있어서 SPECT 검사의 유용성 및 알쯔하이머병에서 전형적인 유형에 영향을 미치는 요인이 무엇인지를 규명한다. 방 법 : NINCDS-ADRDA진단 기준에 의거한 probable AD환자 26명을 대상으로 SPECT 검사를 시행하였으며 이중 14명은 전형적인 SPECT 소견을 보였으며 나머지 12명은 비전형적인 SPECT소견을 보였다. 치매의 정도는 Mini-Mental State Examination(MMSE)에 의하여 결정하였고 SPECT소견은 2명의 핵의학과 전문의의 합의에 의하여 정성적으로 판독하여 분석하였다. SPECT의 전형적인 소견과 연관이 있는 요소들을 확인하기 위하여 판별함수분석을 시행하였다. 결 과 : 알쯔하이머 환자에서 SPECT의 민감도는 53.8%이며, 조기 발병군의 경우에는 민감도가 76.9%이었다. 알쯔하이머의 전형적인 형태인 양측성 두정측두엽에 혈류량이 감소한 경우는 조기 발병군에서 유의하게 관찰되었으며, 이외에 이환기간, 교육정도, 성,병의 진행정도, 아포지단백E등은 유의한 연관성이 없었다. 결 론 : SPECT검사의 민감도는 높지 않으나 이를 조기 발병군에서만 적용하였을 경우 그 임상적 유용성이 높을 것으로 생각되며 조기 발병군에서 SPECT검사의 민감도가 만기 발병군에 비하여 유의하게 높은 것으로 보아 알쯔하이머병이 단일하지 않고 이질적인 집단의 증후군일 가능성이 높을 것으로 생각된다. 즉 SPECT검사가 알쯔하이머병의 진단뿐 아니라 병태생리적 기전의 이해에 도움이 될 것으로 생각되며 앞으로 정량화와 많은 중례를 확보하여 이에 대하여 좀더 규명할 필요가 있을 것으로 생각된다. Objectives : During the past few years, the development of functional brain imaging techniques has allowed to describe brain impairment in cognitive disorders. Among them, based on the observation of bilateral parietotemporal hypoperfusion in Alzheimer's disease(AD), single photon emission computed tomography(SPECT) is advocated by some as powerful diagnostic tool in the evaluation of demented patients. The aim of this study is to investigate the usefulness of SPECT in the diagnosis of AD and to clarify the associated factors of parietotemporal hypoperfusion, the typical SPECT pattern of Alzheimer's disease(AD). Methods : We reviewed the SPECT scans of 26 patients fulfilling NINCDS-ADRDA criteria for probable AD, 14 with typical pattern of SPECT and 12 with atypical pattern of SPECT. Dementia severity was assessed by the Mini-Mental State Examination. Inage interpretation was done visually by the consensus opinion of 2 experienced nuclear medicine physicians who were blind to clinical information. To estimate the association of typical pattern of SPECT with other variables of interest, discriminant function analysis was done. Results : Though the overall diagnostic sensitivity of SPECT in AD was 53.8%, it was 76.9%, in early-onset AD patients. Typical pattern of SPECT was more frequent in the patients with early onset on the symptoms. Duration of symptoms, duration of education, se, severity of disease was not associated with this SPECT pattern. Conclusion : These findings may be useful in the clinical setting and point to heterogeneity of AD according to age at onset.

Comparative studies have been carried out to elucidate effects of 3 types of Japanese hardening agents and cement on the compressive and tensil strength of solidified briquette ashes with different ages, when various mixing ratio were applied. 1. The hardening agent, especially type C, were appeared to be better than the cement to obtain higher compressive and tensil strength of the products. 2. The compressive strength when mixing ratio of 1 : 3 applied were : 177.6kg/㎠ for type C; 168.6kg/㎠ for type A; and 155.94kg/㎠ for type B. 3. The tensil strength when mixing ratio of 1 : 3 applied were : 24.63kg/㎠ for type C; 23.14kg/㎠ for type B; and 22.45kg/㎠ for type A. 4. Although the solidified briquette ashes were found to be not as strong as cement mortar, it is considered that they could be used instead of low-strength concrete, and that they could contribute to reduce the amount of terminal city-wastes then to reduce pollutions caused by the wastes.

어류를 이용한 내분비계 장애물질 검출 및 Biomarker로서 Vitellogenin의 이용

윤석주,김일찬,윤용달,이재성 한국육수학회 2003 생태와 환경 Vol.36 No.2

어류 vitellogenin은 난황전구체로 난형성과정동안에 estradiol의 체내 순환에 의해 암컷의 간에서 생산되며 alkylphenol류와 같은 비이온성 계면활성제 등의 내분비계 장애물질에 의해 수컷에서도 생산된다. 물 환경의 주요 생물종인 어류는 내분비계장애물질에 의해 암컷에서는 번식률 저하와 함께 수컷에서는 정소의 축소 및 이에 따른 암컷화가 관찰된다. 특히 수컷에서 내분비계 장애물질에 의해 유도된 vitellogenin의 생성을 이용하여 환경오염에 의해 유도된 생물체의 유전자 발현 변화 뿐만 아니라 이를 토대로 특정지역의 환경오염을 모니터링할 수 있다. 본 논문에서는 어류의 vitellogenin를 이용하여 수환경의 내분비계장애물질의 검출과 환경오염 모니터링을 위한 biomarker로서의 유용성을 검토하였다. Fish vitellogenin produces in female liver during oogenesis through estradiol cycle, and produces even in male liver by endocrine-disrupting chemicals (EDCs) such as alkylphenols. The resulting effects of EDCs lead to the low fecundity of female and the feminization (eg. shrinkage of testis) in male. Especially, the production of vitellogenin in male indicates the environmental contamination of EDCs, resulting in the modulation fo gene expression profiles and the monitoring of environmental contamination at specific area. In this paper, we suggest that fish vitellogenin is useful for biomonitoring for environmental contamination and would be substantially useful as a biomarker for a detection of EDCs in aquatic environment.
