The general composition like moisture content, and the physical and sensory characteristics of the steamed rice cake added with powder of roots of balloonflowers were as follows. The moisture content in the roots was 4.13±0.01%, crude protein 9.24±0.11%, crude fat 3.07±0.04%, crude fiber 33.82±0.01%, and crude ash 8.16±0.02%. The moisture content of the cake was decreased with increase of the root’s powder added. In physical characteristic, the hardness of the cake was increased with increase of the powder. The control cake was the highest in the cohesiveness. The springiness tended to be increased with increase of the powder. The gumminess was higher with increase of the powder, being 530.33% in the control and 284.44% in the sample with 12.0% powder added. The adhesiveness was decreased with increase of the powder. The color change was significantly decreased with increase of the powder. With increase of the powder, the value a was decreased, while the value b showed to be increased. In a sensory test, the favorite degree to color, flavor, bitter taste, moistness, soft-ness and overall acceptability was measured to get the follow result. To color, the lot with 6% of the balloonflower powder added showed the highest accept-ability with the same highest result also to flavor and bitter taste. The moistness and the softness were revealed as the highest at the control, and the chewiness was also highest at the lot with 3% of the powder added. The overall acceptability was highest as 5.75 at the lot with 6% of the powder added, coming out to be higher in order of the 3% added-lot, the control, the 9%-lot and the 12%-lot.

Atrial natriuretic peptide (ANP), a circulating peptide hormone with 28 amino acids secreted from cardiac atria, plays an important role in the maintenance of fluid and electrolytes homeostasis. The actions of ANP appear to be mediated by specific receptors on target cells. However, the specific antagonist for ANP receptors is not yet to be defined. The present study was undertaken to evaluate the antagonistic effects of water extract obtained from the gardenia (Gardenia jasminoides Ellis) on the natriuretic peptide receptor system in the kidney. In the kidney of Sprague Dawley rats, specific 125I-ANP binding sites were localized in glomerulus, inner medulla, intrarenal artery, and vasa recta bundle by using quantitative in vitro receptor autoradiography. These specific bindings were competitively displaced in a dose dependent manner by water extract obtained from the gardenia. Moreover, productions of 3',5'-cyclic guanosine monophosphate (cGMP) via activation of particulate guanylyl cyclase (GC) by ANP were increased in receptor proteins from the glomerulus and inner medulla of rat kidney. These cGMP productions were inhibited in a dose dependent manner by water extract obtained from the gardenia. The inhibitory effect of water extract obtained from the gardenia on activation of GC was quantitatively more potent rather than on 125I-ANP bindings to these renal structures. From affinity cross-linking study on the specific receptor proteins, the water extract obtained from the gardenia inhibited the 125I-ANP labeling of GC-coupled natriuretic peptide receptor from renal glomerulus of rat. Intravenous infusion of ANP elicits the potent diuresis, increment of urine osmolariry, and excretions of urinary chloride, creatinine and PAH in New Zealand White rabbit. These renal effects of ANP were inhibited by the intravenous pre-treatment of water extract obtained from the gardenia without changes in systemic hemodynamics including mean arterial blood pressure and heart rate. These results indicate that the water extract obtained from the gardenia may could be block the GC-coupled natriuretic peptide receptor, and suggest that the extract may contain a natural antagonistic molecule regulating the renal natriuretic peptide system.

Iridology, developed more than 100 years ago, is the diagnosis of medical conditions through noting irregularities of the pigmentation in the iris The purpose of this study is to compare interrelation between CVA, hypertension family history and cardio-renal connective tissue in Iris Constitution through iris constitution examination. The subjects consist of 114 patients who were examined in Iris Constitution at Chonju Oriental Medicine Hospital attached to Wonkwang Univ. from September. 1st. 2000 to August. 31th. 2002. 1.

These studies were undertaken to evaluate morphological normality and development competence in vitro of hyman oocytes following vitrificatioin using ethylene glycol and electron microscopic grid. Human immature oocytes retrieved from natural and stimulated cycles was vitrified at 0 or 48 h and 0, 8 to 15 or 24 to 28 h after maturation culture, respectively. In oocytes retrieved from unstimulated cycle, no signifciant differences were found in morphological normality (56 to 63%) and fertilization (31 to 37%) rates between the times of vitrification. In stimulated patients, however, more oocytes were morphologically normal when vitrified at 24 to 28 h than when vitrified at 0 or 8 to 15 h after maturation culture. Regardlesss of the hormonal stimulation, high cleavage rates(83 to 100%) were obtained in all treatment groups but did not differ significantly. Twenty to 43% of cleaved oocytes developed to the blastocyst stage at 6 days after IVF. These results suggest that vitrified oocytes from unstimulated and stimulated cycles could develop to the blastocyst stage, regardless of the stages of vitrification.

This experiment was undertaken to investigate the effect of administration of Agyoju or Mokhyang on the maintenance of pregnancy, delivery and sex ratio in the mice in different gestation periods. Adult female mice were administered orally at three different periods, from ovulation to implantation (Exp.1), from post-implantation to organogenesis (Exp.2), and from fetal growth to parturition (Exp.3). In Experiment 1, number of fetus implanted and mean body weight were not significantly different. However, the delivery of male offspring was significantly increased in Agyoju and Mokhyang administrated groups than control group. In Experiment 2, the number of fetuses implanted, live offsprins and their body weight at delivery were significantly increased in the Agyoju administered group than Mokhyang and control groups. In Experiment 3, the number of live offspring and sex ratio were not different in both treatments and control group. However, mean body weight at delivery was significantly increased in both treatment groups than that of control group. These results suggest that 1) Agyoju and Mokhyang have beneficial effects in maintenance of pregnacy, and that 2) The action of unknown component(s) in Agyoju may be related to selection of male spermatozoa for fertilization in vivo, and that 3) the administration of Agyju of Mojhyang during mid-and late-pregnance periods were shown the increment of body weight of live offspring without decrease of litter size.

This paper proposes combination of a cognitive agent architecture named Soar (State, operator, and result) and ROS (Robot Operating System), which can be a basic framework for a robot agent to interact and cope with its environment more intelligently and appropriately. The proposed Soar-ROS human-robot interaction (HRI) agent understands a set of human’s commands by voice recognition and chooses to properly react to the command according to the symbol detected by image recognition, implemented on a humanoid robot. The robotic agent is allowed to refuse to follow an inappropriate command like “go” after it has seen the symbol ‘X’ which represents that an abnormal or immoral situation has occurred. This simple but meaningful HRI task is successfully experimented on the proposed Soar-ROS platform with a small humanoid robot, which implies that extending the present hybrid platform to artificial moral agent is possible.

This paper describes the effect of a robot cognitive rehabilitation program on cognitive functions for the elderly with mild cognitive impairment, and compares it with traditional cognitive therapy programs. Three experiment groups including cognition therapy group, robot cognitive rehabilitation group, and hybrid group have been sampled and one comparative group has been organized for this research. 32 old people whose ages are between 61 and 88 with mild cognitive impairment participated in the programs with an admission of W care hospital. According to the program results, the cognitive therapy program alone had shown a positive effect on the attention function, and the robot cognitive rehabilitation program alone had a positive effect on the total intelligence and memory function. However, a simultaneous operation with both programs had shown a positive effect on the three intelligence areas such as total, basic, and management quotients as well as attention and memory functions as subsidiary factors. This paper has verified that the proposed robot cognitive rehabilitation program makes a positive effect on a cognitive function and plays a complementary role with traditional cognitive therapy programs.

철도교량의 구조적 안전성 및 사용성을 지속적으로 확보를 위해서는 상시적인 계측을 통하여 교량의 구조적 성능을 감시할 수 있는 시스템의 적용이 필요하다. 현재까지 개발된 기법은 대부분 경제성 및 적용성이 뛰어난 가속도계 측정값을 이용하여 추출한 고유진동수, 모드형상 등의 모달응답을 기반으로 하고 있으나, 이러한 추출과정은 동적응답의 수치해석적 후처리과정을 포함하고 있어 구조적 성능평가 결과에 오류를 발생시키는 주요 원인이 되어 왔다. 이 연구에서는 교량에서 추출한 시간영역 회전각을 이용하여 산정한 변형에너지의 변화에 기반한 손상 평가 기법을 제안하였다. 이 연구에서 제안한 방법은 시간영역에서 측정된 가속도값을 이용하여 산정한 구조물의 회전각에 기반하고 있어 모달응답 추출과 같은 별도의 후처리 과정이 없으며 실제 구조물에 적용이 용이하다. 제안된 이론의 적용성을 검증하기 위하여 수치해석을 이용한 검토를 수행하였으며, 검토 결과 제안된 이론은 충분한 사용성을 가지는 것으로 나타났다.

By using the accelerometer, there are two techniques of measuring the response from structures: forced vibration and ambient vibration method. Recently, ambient vibration technique is successfully being used for bridges, buildings, dams, and mechanical structures. In this study, we briefly introduce and describe a health monitoring system which measures and predicts the structural integrity of the entire structure through the measurement of ambient vibration characteristics and tilt of the structure by using the domestic-made high precision accelerometer. The high precision servo accelerometer is applied in inertial navigation system of the various weapon systems such as missiles, tanks, and armored vehicles.
