  • Background: The use of X-ray phase-contrast microtomography for the investigation of Chinese medicinal materials is advantageous for its nondestructive, in situ, and three-dimensional quantitative imaging properties. Methods: The X-ray phase-contrast microtomography quantitative imaging method was used to investigate the microstructure of ginseng, and the phase-retrieval method is also employed to process the experimental data. Four different ginseng samples were collected and investigated; these were classified according to their species, production area, and sample growth pattern. Results: The quantitative internal characteristic microstructures of ginseng were extracted successfully. The size and position distributions of the calcium oxalate cluster crystals (COCCs), important secondary metabolites that accumulate in ginseng, are revealed by the three-dimensional quantitative imaging method. The volume and amount of the COCCs in different species of the ginseng are obtained by a quantitative analysis of the three-dimensional microstructures, which shows obvious difference among the four species of ginseng. Conclusion: This study is the first to provide evidence of the distribution characteristics of COCCs to identify four types of ginseng, with regard to species authentication and age identification, by X-ray phase-contrast microtomography quantitative imaging. This method is also expected to reveal important relationships between COCCs and the occurrence of the effective medicinal components of ginseng.

  • We studied the seroprevalence of four respiratory pathogens in Korean swine farms located in Chungnam, Chungbuk, Gyeongnam and Gyeongbuk provinces during the period of spring of 2007 to winter of 2008. Serological tests were performed using commercial ELISA kits. A total of 530 serum samples were tested for the antibodies against porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), Mycoplasma hyopneumoniae (M. hyo) and Actinobacillus pleuropneumoniae (APP). Seroprevalence for four respiratory pathogens were estimated by ELISA-positive rates of the submitted samples. The overall seropositive rates of PRRSV, APP, M. hyo and PCV2 were 32.6%, 10.6%, 38.4% and 88.5%, respectively. By production stage, the seropositive rate for PRRSV was highest in nursery pig populations (46.2%). In contrast, the highest seropositive rates of APP and M. hyo were observed in sow and growing pigs. However, the seroprevalence of PCV2 was ranged from 85.7% to 89.6%, showing no significant difference among the production stages. In the seroprevalence by season, PRRSV, APP and M. hyo infections revealed typical seasonal patterns that the peaks of the seropositive rates were observed between early winter and late spring. In case of PCV2, no particular seasonal patterns were noticed. The pig herds in Gyeongbuk province where PMWS was endemic during the period of survey showed the highest seropositive rates for PRRSV (44.6%), M. hyo (47.5%), and PCV2 (92.7%). Seropositive rates for APP of four provinces were approximately 10%. These results might be valuable for control and prevention of the respiratory diseases and helpful to define strategies related to vaccine applications.

  • Objective The Constitutional Seong-Jeong therapy is one of the important ways to prevent Sasang constitutional symptomatology. But, there are various interpretations and unclear aspects of the content and meaning, so there are many difficulties in applying it concretely in actual clinical practice. The purpose of this study is to clarify the physiology, pathology, treatment mechanism and its specific meaning. Method The pathology associated with constitutional symptomatology is known as Deepening-Seong and Exploding-Jeong. Therefore, related pathologies and corresponding treatment and prevention mechanisms were reviewed, focusing on the related contents of Donguisusebowon, and their specific meanings were considered. Results and Conclusions 1. Constitutional Seong-Jeong therapy is a regimen to prevent and manage Deepening-Seong and Exploding-Jeong. 2. Deepening-Seong and Exploding-Jeong are the inappropriate occurrences of Seong and Jeong in the poor area of the Heavenly-frame recognition and in the vulnerable area of Humanly-activity practice, and the antecedent cause is covetous desire. 3. Deepening-Seong and Exploding-Jeong cause the weakening in the power of ears-eyes-nose-mouth to perceive Heavenly frame and the power of lung-spleen-liver-kidney to practice Humanly activity in the four constitution's weak system, which lead to the Interruption in processing of four Qi in each weak system. 4. The four constitutions must be careful about the occurrence of covetous desire in the process of recognizing Heavenly frame and doing Humanly activity so that intellectual and behavioral abilities can be exerted to overcome the poor area of the recognition of Heavenly frame and the formation of Humanly activity to prevent deepening-Seong and exploding-Jeong from occurring.

  • Objectives : Ten heavenly stems(10天干) and Twelve earthly branches(12地支) are symbols exposing change order in heaven and earth, and are a very important sign in studying oriental philosophy and oriental medicine. Especially, 10 heavenly stems(10天干) and 12 earthly branches(12地支) are indispensable for the study of Five Circuits And Six Qi(오운육기), and a deep study is needed. Methods : I have examined Yin Yang combination(음양배합), Five elements combination(오행배합), Six Qi 3Yin 3Yang combination(육기삼음삼양배합), viscera combination(장부배합), Mutual collision(상충), Six combination(육합), Three combination(삼합), etc. of 12 earthly branches(12지지) by referring to books such as "Yellow Emperor Internal Classic" ("黃帝內經") and "Principle of universe change" ("우주변화의 원리"). Results & Conclusions : Zi Yin Chen Wu Shen Xu(子 寅 辰 午 申 戌) become Yang(陽), Chou Mao Si Wei You Hai(丑 卯 巳 未 酉 亥) become Yin(陰), Zi Si Yin Mao Chen Si(子 丑 寅 卯 辰 巳) become Yang, and Wu Wei Shen You Xu Hai(午 未 申 酉 戌 亥) become Yin. Twelve earthly branches can be divided into five movements by its original meaning, where YinMao(인묘) is tree, SiWu(사오) is a fire, ShenYou(신유) is a gold, HaiZi(해자) is water, and ChenXuChouWei(진술축미) mediate in the middle of four movements So they become soil(土). SiHai(巳亥) is JueYin Wind Tree(궐음 풍목), ZiWu(子午) is ShaoYin Monarch Fire(소음 군화), ChouWei(丑未) is TaiYin Humid Soil(태음 습토), YinShen(寅申) is ShaoYang Ministerial Fire(소양 상화), MaoYou(卯酉) is YangMing Dry Gold(양명 조금), and ChenXu(辰戌) is TaiYang Cold Water(태양 한수). Viscera combination(장부배합) combines Zi(子) and Bile(膽), Chou(丑) and Liver(肝), Yin(寅) and Lung(肺), Mao(卯) and Large intestine(大腸), Chen(辰) and Stomach(胃), Si(巳) and Spleen(脾), Wu(午) and Heart(心), Wei(未) and Small intestine(小腸), Shen(申) and Bladder(膀胱), You(酉) and Kidney(腎), Xu(戌) and Pericardium(心包), Hai(亥) and Tri-energizer(三焦), Which means that the function of the viscera and channels is the most active at that time. Twelve earthly branches mutual collisions collide with Zi(子) and Wu(午), Chou(丑) and Wei(未), Yin(寅) and Shen(申), Mao(卯) and You(酉), Chen(辰) and Xu(戌), and Si(巳) and Hai(亥). The two colliding earthly branches are on opposite sides, facing each other and restricting each other by the relation of Yin-Yin and Yang-Yang it rejects each other so a collision occurs. Six Correspondences(六合) coincide with Zi(子) and Chou(丑), Yin(寅) and Hai (亥), Mao(卯) and Xu(戌), Chen(辰) and You(酉) and Si(巳) and Shen(申) Wu(午) and Wei(未). Three combination(三合) is composed of ShenZiChen(申子辰), SiYouChou(巳酉丑), YinWuXu(寅午戌), and HaiMaoWei(亥卯未). Three combination(三合) is composed of ShenZiChen(申子辰), SiYouChou(巳酉丑), YinWuXu(寅午戌), and HaiMaoWei(亥卯未). This is because the time Six Qi(六氣) shifts in these three years are the same.

  • Purpose: The purpose of this study was to explore the structure and characteristics of male college nursing students' personality-based career attitudes. Method: The Q-methodology was used to identify factors in male nursing students' personality-based career attitudes. A Q sample was collected from literature reviews (Kim & Kim, 2005). The subjects consisted of 30 male nursing students. Result: The results of the study show that male nursing students can be categorized into four types. The five factors extracted all had eigen values greater than 1.0 and explained approximately 50.84% of the variation in responses (32.62, 7.59, 5.70 and 4.93% respectively). The categories were labeled 'Repair intention style', 'Belief intention style', 'Stability intention style', and 'Self-regulation intention style'. Conclusion: Through a process that analyzes subjective structure, male nursing students' personality based career attitudes create occupational consciousness, professional accomplishment and professional ethics as a nursing profession. Content of curriculum and development of a reasonable and realistic course consultation program should be done.

  • Purpose: This study was designed to analyze recent trends in adolescent suicide intervention research in Korea and to suggest future research directions in this area. Methods: Studies Thirty-four studies selected from http://www.riss4u.net over the for last 20 years were analyzed by field and design of the study, study participants, and the outcome variables used in intervention studies. Results: Nineteen (55.9%) of the 34 studies were conducted in the fields of welfare (9), psychology (5) and nursing science (5). Ordinary adolescents were the most frequently studied participants. A nonequivalent control group pretest-posttest design was used in twenty one (61.7%) of the 34 studies. The most frequently measured outcome variables were depression, suicidal ideation and self-esteem. Conclusion: These results suggest that research on adolescent suicide intervention programs is expanding with a focus on ordinary adolescents as and subjects. In order to prevent suicide, research on family, teachers, and friends, who all are important parts of a teenager's support system, is needed. It is also necessary to develop a post-management intervention program to prevent recurrence in high-risk teenagers who have attempted suicide.

  • Multi-camera systems which integrate two or more low-cost digital cameras are adopted to reach higher ground coverage and improve the base-height ratio in low altitude remote sensing. To guarantee accurate multi-camera integration, the geometric relationship among cameras must be determined through platform calibration techniques. This paper proposed a combined two-step platform calibration method. In the first step, the static platform calibration was conducted based on the stable relative orientation constraint and convergent conditions among cameras in static environments. In the second step, a dynamic platform self-calibration approach was proposed based on not only tie points but also straight lines in order to correct the small change of the relative relationship among cameras during dynamic flight. Experiments based on the proposed two-step platform calibration method were carried out with terrestrial and aerial images from a multi-camera system combined with four consumer-grade digital cameras onboard an unmanned aerial vehicle. The experimental results have shown that the proposed platform calibration approach is able to compensate the varied relative relationship during flight, acquiring the mosaicing accuracy of virtual images smaller than 0.5pixel. The proposed approach can be extended for calibrating other low-cost multi-camera system without rigorously mechanical structure.

  • Measuring the similarity of given samples is a key problem of recognition, clustering, retrieval and related applications. A number of works, e.g. kernel method and metric learning, have been contributed to this problem. The challenge of similarity learning is to find a similarity robust to intra-class variance and simultaneously selective to inter-class characteristic. We observed that, the similarity measure can be improved if the data distribution and hidden semantic information are exploited in a more sophisticated way. In this paper, we propose a similarity learning approach for retrieval and recognition. The approach, termed as LDA-FEK, derives free energy kernel (FEK) from Latent Dirichlet Allocation (LDA). First, it trains LDA and constructs kernel using the parameters and variables of the trained model. Then, the unknown kernel parameters are learned by a discriminative learning approach. The main contributions of the proposed method are twofold: (1) the method is computationally efficient and scalable since the parameters in kernel are determined in a staged way; (2) the method exploits data distribution and semantic level hidden information by means of LDA. To evaluate the performance of LDA-FEK, we apply it for image retrieval over two data sets and for text categorization on four popular data sets. The results show the competitive performance of our method.

  • Tibetans are one of the ethnic Chinese minorities, and this research examined the characteristics and features of their traditional costumes by investigating their historical, geographical and cultural background. This research also examined the cultural elements according to their characteristics based on Tibet's nature, religion, arts culture such as the Jang-po, Chin-sam, Kam-kjun and belts, which are used to fix the costumes. Based on such studies the traditional Tibetan costumes were set as a motif and were expressed appropriately into a contemporary style. By studying the composition of its costumes and its costume culture, the characteristics of the Tibetan costumes could be classified into four features. First, the 'variability of form' expresses a new type depending on how it is worn. Second, the 'color contrast' shows a strong visual contrast. Third, the 'difference of materials' combines different materials into one. Fourth, the 'symbolic meaning' grants meaning to the wearer. As a result of this study, by using the characteristics of the Tibetan nature culture, religion culture and art culture as a basis, two suits of clothes for each characteristics and six suits of clothes were produced as a fashion design product.

  • Objective : This study was conducted to find the relationship between syndrome-differentiation and Sasang-constitution in chronic fatigue patients. Methods : The subjects were 72 adults with chronic fatigue who visited Dunsan Oriental Hospital of Daejeon University between March 2007 and April 2007. Their main complaint was fatigue for longer than 6 months and they did not have any physical or mental problems. We measured their fatigue degree by using Chalder fatigue scale and health habits. To evaluate relationship between syndrome-differentiation with sasang-constitution, The patients were divided into four syndrome-differentiations, such as liver and kidney asthenia of Yin, spleen and kidney deficiency of Yang, deficiency of lung and spleen qi, and deficiency of heart and spleen blood. We also diagnosed Sasang-constitution by using Questionnaire for Sasang Constitution Classification II (QSCCII). Results : Among the 72 patients, 41.4%, 34.5% and 24.1% of belonged in Soyangin, Soeumin and Taeumin respectively. Interestingly, we found a meaningful correlation between syndrome-differentiation and physiological function by Sasang-constitution. Conclusion : The result may help Oriental medicine understanding and treatment of chronic fatigue-related diseases and patients.
