본 논문에서는 스테레오 카메라를 이용하여 텍스처가 없는(Non-texture) 물체를 인식 할 수 있는 기법을 제안하였다. 텍스처가 없는 물체란 표면에 무늬가 거의 없는 물체를 의미한다. 이러한 물체의 경우에는 텍스처로 부터 물체 인식에 필요한 특징들을 추출하는 기존의 기법들을 적용하기 어렵다. 본 논문에서는 이러한 문제점을 극복하기 위해 물체의 색, 크기, 모양 정보를 바탕으로 물체를 인식할 수 있는 방법을 제안하였다. 영상이 입력되면 먼저 미리 학습된 컬러 특징을 이용하여 물체의 후보영역을 설정한다. 그 후 검출된 모든 후보 영역들의 모양 정보와 스테레오 매칭을 통해 계산된 크기 정보를 종합하여 최종 인식 결과를 도출하게 된다. 제안한 방법은 단 하나의 학습 샘플만을 이용하여 필요한 정보들을 학습하며, 실시간으로 텍스처가 없는 물체를 인식 할 수 있게 해준다. 또한 인식된 대상 물체의 3차원 좌표 정보 역시 제공해 준다. In this paper, we propose the method for non-texture object recognition using stereo camera. Non-texture objects mean textureless objects in its surface. Most of existing object recognition techniques are difficult to use to recognize textureless objects because they extract needed features from the texture of the target object surface. To deal with this problem, the proposed method recognizes the non-texture object by using color, size and shape information. First the candidate regions are detected through pretrained color features in the input image. And, for each candidate region, the shape and the size information which is calculated through stereo matching are evaluated to output final recognition results. The proposed method trains features from only one training sample and it can recognize non-texture objects in real time. This method also provides three dimensional location of the recognized object.

This study was performed to figure out the effects of I-razin in overweight children without any exercise or specific diet. Methods Twenty-eight children those who were diagnosed overweight have been recruited. They were randomly assigned treatment or control group under block randomization. Treatment group were treated with I-razin for 8 weeks, and control group were treated with placebo medication under same conditions. Anthropometry, fat computed tomography and blood test have been done before and after the treatment. Results Eleven subjects in treatment group and seventeen in control group were evaluated. BMI, waist circumference, glucose, total cholesterol, and triglyceride were decreased in the treatment group. And reduction of BMI, glucose, and triglyceride in the treatment group were greater than control group. But there was no statistically significance. No side effects have been notice during the study period and no adverse effect on liver has been observed. Conclusion This study could not demonstrate effect of I-razin compared with control group. However, treatment group has a tendency of weight loss without side effect. Additional studies with large population are thought to be necessary to clarify the effect of I-razin.

Acid α-glucosidase (GAA) was produced in transgenic rice cell suspension cultures. In order to solve the problems using RAmy3D promoter for the efficient expression of GAA under sugar starvation condition, sorbitol was used as an alternative carbon source. Cell viability could be prolonged up to 27 days when sorbitol was present. Protein expression could also be enhanced. In addition, N-acetyl glucosamine, a hexokinase inhibitor, was used as a regulator for the RAmy3D promoter to shorten the incubation time with improved GAA expression. When sorbitol and N-acetyl glucosamine were used together, production of GAA was higher than that with sorbitol only. In order to optimize the combination condition, various experimental sets were designed and 60% increased protein could be obtained. In conclusion, optimized utilization of sorbitol as an alternative carbon source with N-acetyl glucosamine in transgenic rice cell suspension cultures was found to be the best condition for the enhanced expression of GAA using RAmy3D promoter.

Objectives: This study was performed to figure out the effects of herbal mesotherapy on abdominal fat in obese women. Methods: Forty obese women those who were diagnosed abdominal obesity had been recruited during February, 2008. They were randomly assigned experimental or control group under block-randomization. Experimental group were treated with Sobi-eum(Xiaofei-yin) injection during 6 weeks (2 times a week) and placebo group were treated with normal saline injection under same procedures. Anthropometry, body impedance analysis, fat computed tomography, blood test, and questionnaires had been administered before and after the treatment. Results: Four subjects were dropped out (voluntary give up), so 18 in experimental group and 18 in placebo group were evaluated. There were significant changes after treatments in both groups. Although no significant differences have been found in the result of anthropometry, body impedance analysis and fat computed tomography between two groups, in the experimental group, the changes of total fat area had a highly significant relationship with all part of abdominal fat. While the placebo group had highly significant relationships with subcutaneous fat area, superficial and deep subcutaneous fat area but not with visceral fat area. Conclusions: Compaired with saline group, herbal mesotheraphy Sobi-eum(Xiaofei-yin) is effective in reduction of visceral fat after adjusting TFA.

The purpose of this study was to investigate the effects of aerobic exercise with unstable supporting surface on cardio-pulmonary function and balance ability. Methods : This study was performed on 20 subjects. The subjects were divided into two groups; stable supporting surface group(Group Ⅰ, n=10), unstable supporting surface group(Group Ⅱ, n=10). The groups performed the aerobic exercise, which is jump rope exercise, 2 times a week for 4 weeks. Results : The results were as follows. There was statistically significant difference of cardiovascular endurance in Group Ⅰ(p<0.05), and there were statistically significant difference of cardiovascular endurancedynamic, OSI and dynamic APSI in Group Ⅱ (p<0.05). However, there were no statistically significant difference in pulmonary functions which were FVC and FEV1 in Group Ⅰand Group Ⅱ. Conclusion : As a result of this study, aerobic exercise with unstable supporting surface have a potential to induce positive responses in cardiovascular endurance and dynamic balance ability of healthy adults.

To shorten processing time for variety of medical affairs of the patient at the outpatient clinic of a big hospital is very important to qualify medical care of the patient. Therefore, patient's waiting time for medical examination is often utilized as a strong tool to evaluate patient satisfaction with a medical care provided. We performed this study to investigate factors delaying related with waiting time for medical examination. The data were collected from June 2 to 14. A total of 242 cases were used as final data for our analysis, selected from the patients waited more than 30 minutes who visited outpatient clinics of a general hospital in county areas of Jeonbuk province. The data were analyzed using frequency, t-test, ANOVA by SPSS 12.0 for windows program. As a result, the mean patient's waiting time was 45.79±18.443 minutes. Patient's waiting time was statistically significant difference in medical departments, day of the week, and factors delaying. The result show that, besides the starting time of medical examination, consultation hours and patients arriving time, may influence the patient's subjective evaluation of waiting time. In oder to improve patient satisfaction related with waiting time, it will be effective to change of reservation system (as revision of reservation interval) for medical examination rather than to shorten the real processing time within the consultation room.
