환자의 입 냄새로 질병을 구분했다는 기록은 고대 동서양의 역사에서 많이 찾아볼 수 있다. 최근 훈련된 개가 냄새로 암환자와 정상인을 구분했다는 뉴스가 보도 되었다. 호흡가스의 분석을 이용한 질병 검진은 병원에서 진행되고 있는 기존의 고가의 장비나 혈액 채취를 이용한 방법과 비교할 때 검진자와 피검진자가 손쉽게 저가로 진행될 수 있다는 장점이 있다. 최근 인체 호흡가스 분석법에 대한 연구개발이 미국과 유럽 국가를 중심으로 활발하게 진행되고 있다. 현재는 폐암, 폐결핵, 천식 등 주로 호흡기 관련 질병에 대한 분석법이 주를 이루고 있지만, 질병과 호흡가스 성분의 연관성이 밝혀짐에 따라 호흡가스 분석에 근거한 질병 진단은 미래의 다양한 질병 진단법으로 등장할 것으로 예상된다. 본고는 최근 호흡가스 분석법으로 응용되고 있는 질량 분석법과 가스 센서 어레이 기술의 현황 및 이들의 질병 진단 응용에 대해 전망하였다.

Objectives: In this study a pattern questionnaire for damum patterns was developed by means of literature review and statistical analysis. The individual approach of korean medicine is based on the concept of pattern identification, the objectivity and validity issues of which hold important meaning in the pratice and research. Methods: Review of literatures led to the selection of 22 items describing Dam or Um pattern. A preliminary questinnaire consisted of these items that may be scored with positive score at zero to seven. Results: Damum is all over the body syndromes. That is abnormal body conditions. Damun arouse body pain, breath disorder, digestion disorder, nerves disorder, excretion disorder. Conclusions: Review of literatures led to selection of 29 items describing Damun. A questionnaire is in preparation.

Abdominal circumference changes due to breathing by the respiratory muscle activity such as diaphragm, which would partially represent the lung volume variation. The present study introduced conductive rubber molded in a cord shape incorporated with a patient's pants. The conductive rubber cord operated as a displacement transducer to measure the lung or abdominal volume changes. Signal extraction circuitry was developed to obtain the volume and its derivative(or the flow) signals followed by wireless transmission based on the Zigbee communication protocol in a size of $65mm{\times}105mm$ easily put in pocket. Breathing frequency was accurately evaluated and breath pattern analysis seemed feasible, since respiratory behaviours such as maximal inspiration and cough were well identified. Remote wireless receiver module also enabled to monitor both volume and flow signals during resting breathing on a PC terminal.

Optimizing the performance of a composite sensor array is necessary when the number of sensors to choose from is large. In this paper, we present a chemical sensors array optimization method using Wilks Lamda algorithm applicable a device to detect low concentration of alcohol from driver's exhale breath for interlocking engine ignition preventing drink-driving. More than 20 chemical sensors fabricated different synthetic stuffs and heater temperatures by collaborators were nominated, 5 sensors were selected for optimal sensors array using the method, and alcohol samples were well discriminated from the interference gases inside the vehicle. It has been confirmed by Principal Component Analysis (PCA).

This study examined the characteristics of the relationship of home environment variables and preschool children's intelligence, learning readiness and socio-emotional developments. The subjects of this study were 63 children at age five and their mothers. Instruments included the children's intelligence test, preschool inventory for learning readiness, the socio-emtional rating scale and the inventory of HOME. The data of the present study were analyzed by the statistical methods of Pearson's product-moment correlation coefficient and step-wise multiple regression analysis. The kinds of HOME variables that significantly predict children's intelligence were "need gratification and avoidance of restriction" "quality of language environment" "play materials" "aspects of physical environment" "organization of stable and predictable environment". The variables that significantly predict children's socio-emotional developments were "breath of experience" "fostering maturity and independence" "developmental stimulation". All of the HOME variables were not significantly predict children's learning readiness. The kinds of HOME factors that significantly predict children's intelligence were factor II and factor III. Factor I predicted children's socio-emotional developments significantly. All of the HOME factors were not significantly predicted children's learning readiness.

본 논문에서는 호흡에 의하여 변화하는 기도 내부 영역의 형태학적인 정보를 반영할 수 있는 EBCT를 이용한 영상 획득 기법과 이 기법을 이용하여 획득한 단층 영상으로부터 기도 내벽의 윤곽선을 자동적으로 검출하는 방법을 제안하였다. 기도의 각 준위에 대한 영상데이터들을 적용한 컴퓨터 시뮬레이션 결과들을 통하여 제안한 방법이 효과적으로 기도의 윤곽선을 검출함을 확인하였으며 시간적 변화에 따른 기도 내벽의 단면적인 변화를 볼 수 있었다. 따라서, 제안한 방법이 임상에서의 정량적 평가에 활용할 수 있을 것으로 판단된다.

To enhance web site's usability, it has been suggested that the depth of tree structured menus should be minimized. In this research, experimental results are reported to quantitatively compare the methods currently used for reducing the depth of menus in web sites. 25 popular web sites were selected and their menu types were categorized into four types: top menu, drop-down menu, boolean menu, and table of contents. The four types of menu were then sub-categorized into 15 different types according to their sub-menu type, existence of menu colors, and the event occurring after mouse activation. Performance tests and subjective evaluation were carried out. The results showed that there were no significant differences in terms of response time among the 15 menu types, while table of contents and drop-down in which the first and second level of menus were visible induced the least number of errors. In the subjective test, the top-menu structure with colors and presentation of its sub-menu without clicking mouse were preferred.

Melissa parviflora Benth. is an aromatic perennial herb of Lamiaceae family. It is one of the most influencial plant and used from centuries in Unani system of medicine for the treatment of various malady such as Epilepsy (mirgi), hemiplegia (falij), migraine (shaqeeqa), insomnia (sehar), indigestion (sue hazm) and palpitation (khafqaan) etc. The Persian physician Avicenna endorsed it for heart problems. It has antitubercular, antipyretic, analgesic and stomachic properties, also used to remove bad breath from mouth, strengthen the gums but its main action is as a tranquillizer and nervine relaxant, it is greatly esteemed for its calming properties. Preliminary performed phytochemical analysis revealed that tannin, flavonoid and saponins are the major components of the plant extract. The plants containing saponins or flavonoids exhibit anticonvulsant activity whereas the flavonoids show various biological activities including antioxidant, anti-inflammatory and cytotoxic-antitumor etc. Keeping in view the tremendous medicinal importance of the plant Badranjboya in Unani Medicine, this review provides updated information on its phytochemistry, therapeutic uses and pharmacological properties.

Gastric cancer is the fifth most common malignancy in the world and still remains the third and fifth leading cause of cancer death in male and female, respectively. In terms of the cancer survival, the survival of gastric cancer is low in the West with showed 5-year survival rates of 10-30%, whereas the survival rates in Asia is more than 50%. The reason of the higher survival rate from gastric cancer in Asia partially related with the availability of gastric cancer screening programs, however, the population-based screening for gastric cancer has been conducted just in Korea and Japan. Therefore, more effective method for detecting the gastric cancer is needed for countries without a population-based gastric cancer screening. Endoscopy is the most effective method for diagnosis of gastric cancer however, it requires a large infrastructure including a large number of endoscopic equipment and well-trained endoscopists. To overcome these problems, several noninvasive methods (such as serologic markers, biomarkers, cancer autoantibodies, and exhaled breath analysis) for diagnosis of gastric cancer screening are suggested. This review addresses the conventional methods and the emerging methods for gastric cancer screening.

The 181,000 DWT Bulk Carrier has a different deck house type, which is not typical for previous bulk carriers, to meet the new international rules for bulk carriers. This new deck house has much smaller transverse breadth than the hull's transverse breath, resulting in large levels of the transverse response of the deck house. In addition, the longitudinal response of the funnel showed rather a large magnitude of vibration, which are excited by the ship's main excitations such as the main engine H-moment and the propeller surface forte when the ship operates at the NCR and the MCR speeds In the ballast condition. To solve these issues, the global forced vibration analysis has been performed for the ship and the ship structure has been modified to reduce the vibration level by increasing the girder depth and adjusting the engine room tank arrangement.
