  • The quality characteristics and processing of rice cake (Backsulgi) with rice flour containing Lactobacillus plantarum CGKW3 by spray-drying (LP-B) were investigated. The LP-B was applied at ratios of 10, 20, and 30 (w/w), and the moisture contents and pH were 33.39%~36.70% and 5.81~5.46, respectively. The L value of LP-B increased as the rice flour decreased, while the a and b value increased as the LP-B increased. The texture profiles showed that Backsulgi prepared with LP-B mixture had higher hardness, cohesiveness, springiness and chewiness than 100% rice flour. The pH of LP-B Backsulgi (LP-B20 and LP-B30) did not differ during 6 days at room temperature. The total bacteria in Backsulgi prepared LP-B20 and LP-B30 Backsulgi was $10^4CFU/g$ after 2 days of storage at room temperature. The shelf life of Backsulgi prepared with LP-B20 and LP-B30 were extended by about 2 days when compared with the control at room temperature. Sensory evaluation showed that Backsulgi without LP-B20 had higher scores in terms of appearance, color, flavor, taste, texture, hardness and overall acceptability than Backsulgi without 100% rice flour. In conclusion, the results demonstrate that LP-B20 may prove quite useful as a Backsulgi flour with desirable properties.

  • The objectives of this study was to examine the effect of Interactive Video Game on cognitive information processing the elderly. Sixty elderly were attended in this study. Their ages ranged from 65 to 70, with a mean age of 67.60 years. The subjects were randomly assigned to one of three experimental conditions: (1) interactive video game group (n=20), (2) aerobic exercise group (n=20), (3) control group (n=20). The experimental design of this study was analyzed using two-way ANOVAs with repeated measures of groups and time. Cognitive function was assessed by neuroelectrical response, and ERP analysis. The results of the study showed that the interactive video game group and aerobic exercise group showed no significant statistical differences in the response time, response accuracy, amplitude and potential of the performance of the exercise in cognitive function and ERP analysis, but improved the interaction video game group and aerobic exercise (walking) group over the control group. It was concluded that long-term aerobic exercise like interactive video game is associated with attenuation of cognitive decline in the elderly.

  • The restoration of cultural heritage materials is an important research theme. This study improved the existing cultural heritage restoration method and attempted to establish a restoration system for cultural heritage data based on historical documents and visual materials. Recognizing the limitations of existing studies, this paper attempted to restore cultural heritage data through interdisciplinary research. In addition, 3D restoration was carried out after restoration in 2D form based on literature documents rather than existing visual sources. The object of restoration that was selected was "Jeol," which represents the power of the king of Koguryo. Koguryo's Jeol is a type of flag. Jeol appears in the mural in Anak Tomb No. 3. Rather than using only photographic materials of murals, the restoration was carried out through cross-validation of literature data and materials on archaeological art history. This is important in that the restoration carried out in this study is an accurate restoration with a historical understanding based on the literature of the relevant cultural heritage. In this study, a restoration process based on historical records was established. A 3D restoration process was performed by adding and applying visual materials after the object was first shaped based on the literature data. Restoration based on literature and visual materials was carried out based on interdisciplinary research. Therefore, this study aims to build a digital restoration system for cultural heritages and to contribute to spreading the 3D digital restoration research of cultural heritages that can be applied to various platforms.

  • 전라남도 진도군 내에서 사육되는 진돗개에서 발생한 유산의 일부가 Brucell canis 에 의하여 유발된 것임을 확인하였다. 이 연구에서는 먼저 1997년 7월에서 1998년 6월 사이에 발생한 진돗개의 유산을 설문조사로 확인하였던 바 발생률이 18.5%에 달했다. 이어서 설문조사에 포함된 지역에서 사육되는 진돗개를 대상으로 신시한 혈청학적 조사에서는 25%가 양성을 보였으며, 수캐의 양성률은 암캐의 거의 두 배에 달했다. 다음으로 균 분리와 치료시험을 실시하기 위하여 유산 병력을 기치고 있으면서 혈청검사에서 양성을 나타낸 암캐 다섯 마리를 현지에서 구입하였다. 그 중 세 마리는 안락사 시킨 후 부검하여 자궁을 검사하고 균 분리를 시도한 바 세 미리 모두에서 B. canis가 분리되었다. 그러나 육안적 및 조직학적 변화 는 현저하지 않았다. 나머지 두 마리는 minocycline과 streptolmycin으로 치료하였는데, 치료를 끝낸 후 8주에 실시한 혈청검사에서 음성을 보였다. 이 연구의 결과는 개 부루셀라병이 진돗개를 사육하는 농가에 경제적 손실을 초래하고 있음을 나타내준다. 아울러 대부분의 진돗개가 방사되고 있으며, 그렇게 사육된 개들이 전국적으로 팔려나가고 있기 때문에 진돗개가 개 부루셀리병의 전파원으로 작용할 가능성을 지니고 있음을 나타내준다 천연기념물인 진돗개의 보 호와 농가의 소득 그리고 공중위생학적인 면에서 진품개의 부루셀라병에 관한 연구는 지속적으로 수행되어야 할 것으로 사료된다.

  • As yet the use of 3D scanning technology has been limited to documentation, preservation and monitoring in cultural and natural heritage domain. Appropriate visualization of precise geometric information in scan data can support scientific interpretation of the domain experts. We studied the rendering techniques which visualize the required features from scanned models, and proposed a 3D scan data visualization pipeline, rendering methods, and a classification scheme. As a case study, we analyzed the traditional method in the study of dinosaur tracks and performed the visualization of 3D scanned models. A user test based on the result confirmed an effectiveness of the proposed method. This research showed a practical method in which 3D scanned models can be used to effective interpretation of heritage.

  • The purpose of this study is to demonstrate that transmissions of an intangible cultural heritage in Korea may be cut off because it is separated from human and social environment and protected and managed under the national system. In addition, another purpose is to criticize concept and method dichotomy in the current institution from an ecological perspective and consider the problem that the intangible cultural heritages are transmitted mainly by holders having skills and accomplishments by distinguishing them from others. Furthermore, the last purpose is to suggest a direction of policy emphasizing an importance of establishment of environment which allows nurture, change and development of local people, which may ensure continuous transmission in order to solve the problem and a transmission system of the intangible cultural heritage by using a principle in which the system is operated by self-recovery and natural rule of the ecology. The findings of this study show that seven problems can be analyzed by reviewing concept establishment and protection and transmission measure of intangible cultural heritages according to the Cultural Properties Protection Law, based on the ecological perspective. The protection and transmission methods of the intangible cultural heritage through the cultural heritage ecology are suggested by applying ecological theory to it. The intangible cultural heritage ecology defined in this paper means 'a sustainable community consisting of intangible cultural heritage, subject of activity and physical environment.' Since it is operated according to the principle reflecting the rules and features of natural ecology, it can keep system through self-recovery without an external intervention, as the case of natural ecology.

  • Java, a platform independent object-oriented programming language, is widely used, however it should be integrated with JNI to use system services or to reuse legacy systems. Though JNI provides the standard APIs which allow Java to be combined with C/$C^{++}$, it is very hard and cumbersome for developers to use JNI APIs. In order to address this problem, we introduce a translator named C2JNI, which converts the embedded C program into a JNI compatible C program. With C2JNI, developers can Integrate Java and C programs without JNI APIs, and it will reduce the complexity caused by JNI APIs.

  • It is well known non-drug therapy for hypertension patients can reduce blood pressure. These types of therapy include maintaining ones ideal body weight, quitting smoking, consuming large amounts of fruits and vegetables consuming low levels of saturated fat and salt and regular exercise. Fermented milk protein derived biologically active peptides such as isoleucine-proline-proline_(IPP) or valine-proline-proline_(VPP) have been shown to lower blood pressure in hypertensive subjects. This study was conducted to investigate the antihypertensive effects of medical nutritional therapy _(MNT) in accordance with the consumption of fermented milk enriched with IPP and VPP. To accomplish this, we conducted a randomized case-controlled study of 43 subjects who had blood pressure levels greater than 120/80 mmHg. The subjects in the study group were randomly allocated into two groups, an MNT + fermented milk (100mL/day) group (n=21) and an MNT+L. helveticus fermented milk with tripeptides (IPP=2.2mg, VPP=2.6mg/100mL) group (n=22). The MNT included weight management, reduction of sodium, total fat and saturated fat intake, increased intake of fruits and vegetables, and increased intake of low fat dairy products. The treatments were administered for 12 weeks during which time no drug interventions were conducted. The daily intakes of total calories, fats, cholesterol and Na decreased significantly after 12 weeks of MNT in the control and the experimental groups. In addition, the systolic blood pressure de creased significantly in the control and experimental groups; however, the diastolic blood pressure only decreased significantly in the experimental group. Overall, the results of this study indicate that the intake of fermented milk containing IPP and VPP in conjunction with MNT exerted positive effects on the blood pressure of pre- and hypertensive subjects.
