This Thesis analyzes the two forms of Confucian Golden Rule(Shu恕) that were proposed by Zhu Xi朱熹 and Dai Zhen戴震 each other, and researches their ethical significances. Zhu Xi don't regards Shu as universal ethics by itself, while Dai Zhen identify Shu as the ground of universal ethics, According to this thesis, Zhu Xi thought that Shu has a danger of immoral misusage in some situation because Shu is so simplistic form of identification. Because this, Zhu Xi, for the purpose of blocking arbitrary misusage of Shu and holding universality of ethics, suggests that moral sincerity(Zhong忠) of subject is necessary to practice of Shu. Dai Zhen, however, criticizes Zhu Xi's Ethical Structure. In Dai Zhen's view, Zhu xi's idea that the subject has to establish his own morality through Zhong before practice Shu cannot make him escape from subjectivity necessarily. In this point, Dai Zhen revive Shu. His Shu concept means the reciprocity of human desires to each other. But Dai Zhen's idea, as Zhu Xi worried, has a danger of immoral misusage in some situation. On this problem, this thesis elucidates that Dai Zhen' desire concept is not individual various desires but is common basic desires of existence, thereby attests that Dai Zhen's Shu is safe from immoral misusage. This thesis claim that even if Zhu Xi's and Dai Zhen's position is so different, the ethical aims of two scholars is same. They both attempted to overcome the evil of subjectivism and to procure universality of ethics, furthermore to accomplish social fairness. Consequently, this thesis claims that two scholars both walked in same way because both wanted to establish the universality of Shu and to pursue realization of social fairness.

In this paper, we propose a social-based collaboration systems for business process management in the mobile cloud. This XMDR-DAI is to provide services for data sharing and exchange between local systems that operate independently in a cloud environment, take charge of a social-based collaborative business process management. Social-based collaborative business processes are handled in a collision among a structure such as unit conversion, meaning conflict, and the schema mapping data resulting from the inner query. The conflict was resolved by mapping process which takes in each XMDR-DAI.

Objective: To assess the prevalence of malocclusion and its relationship with dental caries among school children in southern India. Methods: This cross-sectional study included 1,800 students aged 11 - 15 years whose Dental Aesthetic Index (DAI) and dentition status were recorded and analyzed. The chi-square test, ANOVA, and Spearman's correlation tests were carried out. Results: The mean DAI score ${\pm}$ the standard deviation was $18.61{\pm}6.1$. Approximately 85% of the students (83.0% males, 86.8% females) had DAI scores of < 26 and were classified as not requiring orthodontic treatment. One tenth of the sample had mean DAI scores between 26 - 30 (indicating definite malocclusion and elective treatment), while about 3% had mean scores between 31 - 35 (indicating severe malocclusion and treatment desirability). Only 29 children (1.6%; 16 boys, 13 girls) had a DAI score of > 35, which suggested very severe or handicapping malocclusion requiring mandatory treatment. The mean decayed, missing, filled teeth (DMFT) was $2.28{\pm}1.47$. A DMFT of > 0 was observed in 91.8% of the study subjects. Children with a DAI score of > 35 were found to have significantly (p < 0.001) higher caries experience as compared to other children. Moreover, the DAI scores showed a significant correlation with the mean DMFT scores (r = 0.368, p < 0.05). Conclusions: A positive correlation was found between the severity of malocclusion and dental caries.

Ubiquitous Sensor Network (USN) environments, sensors and sensor nodes, and coming from heterogeneous sensor networks consist of one another, the characteristics of each component are also very diverse. Thus the sensor and the sensor nodes to interoperability between metadata for a single definition, management is very important. For this, the standard language for modeling sensor SensorML (Sensor Model Language) has. In this paper, sensor devices, sensor nodes and sensor networks for information technology in the application stage XMDR-DAI -based metadata to define the USN. The proposed XMDR-DAI USN based store and retrieve metadata for a method for effectively agent technology. Metadata of the proposed sensor is based SensorML USN environment by maintaining interoperability 50-200 USN middleware or a metadata management system for managing metadata in applications can be utilized directly.

Multiple features of occlusion have been combined by epidemiologists in attempts to objectively to determine malocclusion severity and treatment priority. Jenny et al were developed DAI(Dental Aesthetic Index), which is an orthodontic index based on socially defined aesthetic standards. This study aimed to evaluate association between 10 occlusal components of DAI and individual measures of skeletal morphology by use of univariate and multivariate analysis. In addition the relationship between a Dental Aesthetic Index score and skeletal morphology was evaluated. The data for this study were obtained from cephalometric radiographs and dental casts of 182 Korean patients(79 men, 103 women) with permanent dentition who had been accepted for the orthodontic treatment at Department of Orthodontics, Chonbuk National University. The results are as follows: 1. Several occlusal components of DAI(missing, crowding and spacing in the incisal segment, diastema, largest anterior irregularity on upper and lower arch) were not associated with individual measures of craniofacial morphology. 2. Sagittal occlusal components of DAI were associated with anteroposterior skeletal measures. 3. The relation between vertical occlusal components of DAI and vertical skeletal measures was low magnitude. 4. A Dental Aesthetic Index, which is based on several aspects of occlusion, did not identify craniofacial morphology. We can conclude that combination of certain occlusal components of the DAI may be related with specific skeletal morphology; but, this concept could not be accepted generally.

We examined and referred to some literatures on the meaning, Dai meridian and Meridian points of joining with circulation of Dai meridian through literatures of every generation. And then we came to get a few conclusions as follows. 1. Dai meridian starts below the hypochondriac region. Running obliquely downward, it runs transversely around the waist like a belt. Its function is to bind up all the meridians to circulate in a proper way. 2. The coalescent points of dai meridian are $D\grave{a}im\grave{a}i$(帶脈), $W\check{u}sh\bar{u}$(五樞) and $W\acute{e}id\grave{a}o$(維道). 3. Location of $D\grave{a}im\grave{a}i$(帶脈) is on the lateral side of the abdomen, 1.8 cun below $Zh\bar{a}ngm\grave{e}n$(章門), at the crossing point of vertical line through the free end of the 11th rib and a horizontal line through the umbilicus. Location of $W\check{u}sh\bar{u}$(五樞) is on the lateral side of the abdomen, anterior to the anterosuperior iliac spine, 3 cun below the level of the umbilicus. Location of $W\acute{e}id\grave{a}o$(維道) is on the lateral side of the abdomen, anterior and inferior to the anterosuperior iliac spine, 0.5 cun anterior and inferior to $W\check{u}sh\bar{u}$(五樞). 4. Indication of $D\grave{a}im\grave{a}i$(帶脈) is irregular menstruation, leukorrhea with reddish discharge, hernia, pain in the lumbar and hypochondriac region. Indication of $W\check{u}sh\bar{u}$(五樞) is prolapse of the uterus, leukorrhea with reddish discharge, irregular menstruation, hernia, pain in the lower abdomen, constipation and lumbosacral pain. Indication of $W\acute{e}id\grave{a}o$(維道) is edema, pain in the side of the lower abdomen, prolapse of the uterus, hernia and morbid leukorrhea. 5. The Dai meridian binds all meridians, produces pregnancy, grasps lumbar and abdomen region and controls leukorrhea. 6. Diseases of the Dai meridian manifested as distention and fullness in the lumbar region and abdomen, leukorrhea with reddish discharge, pain the navel, lumbar and spinal regions, flaccidity and hypoactivity of the lower limbs, etc.

Companies have made an investment of cost and time to optimize processing of a new business model in a cloud environment, applying collaboration technology utilizing business processes in a social network. The collaborative processing method changed from traditional BPM to the cloud and a mobile cloud environment. We proposed a collaborative system for operating processes in social networks using MOXMDR-DAI+ (eXtended Metadata Registry-Data Access & Integration based multimedia ontology). The system operating cloud-based collaborative processes in application of MOXMDR-DAI+, which was suitable for data interoperation. MOXMDR-DAI+ applied to this system was an agent effectively supporting access and integration between multimedia content metadata schema and instance, which were necessary for data interoperation, of individual local system in the cloud environment, operating collaborative processes in the social network. In operating the social network-based collaborative processes, there occurred heterogeneousness such as schema structure and semantic collision due to queries in the processes and unit conversion between instances. It aimed to solve the occurrence of heterogeneousness in the process of metadata mapping using MOXMDR-DAI+ in the system. The system proposed in this study can visualize business processes. And it makes it easier to operate the collaboration process through mobile support. Real-time status monitoring of the operation process is possible through the dashboard, and it is possible to perform a collaborative process through expert search using a community in a social network environment.
