Along with the social interests and needs for health, the U-Healthcare Service as a new model to control individual dietary life and to prevent chronic diseases is now drawing the public attention. In this study, the characteristics of the requirement of U-Healthcare Service were investigated from subjects aged over 50 years old. As parts of the expectation to the U-Healthcare service, the customized clinical care & control (37.7%) and the systematic understanding of individual health state (21.4%) appeared significantly. And for the application of the U-Healthcare Service to the field of healthcare, the control of dietotherapy (43.9%) appeared higher than anything else and thus the customized service for individual dietotherapy seemed to be needed. Regarding the field of searching for health information, the disease control (35.6%), food materials (28.6%), and recipe for health foods (22.7%) appeared in sequence and revealed that the majority over 50% of subjects were interested in foods. The requirements for the information of dietary formula were also investigated through 5 points scaled questionnaires on respective topics of nutritive components, menus customized for corresponding health states (diseases), and the results obtained from surveys on respective topics all showed the needs for all information by representing each point value exceeded 3.9. Through the results obtained from this study, the provision of customized information enabling the nutritional control in accordance with individual states of health or disease was estimated to be needed for the popularization of U-Healthcare Service providing contents for dietary life of clients especially those of aged over 50 years.

Although social relation factors are confirmed to be closely associated with the depression level of the elderly through the preceding studies, there has been no specific study on subfactors of social relation that influence the trajectory of depression level. Considering such limitation, this study aims to analyze influencing subfactors of social relation on the trajectory of depression of the elderly. The 3rd, 4th, 5th, and 6th-year data of the Korean Longitudinal Survey of Ageing (KLoSA), which were provided by the Korea Employment Information Service (KEIS), were used in this study and 2,484 people aged 65 and over who responded to all the four-session surveys were used as final analysis subjects. In the result of the longitudinal study on depression level of the elderly aged 65 and over, the individual depression level was confirmed become lowered over time, showing a positive change. Also, the conditional model of Latent Growth Modeling (LGM) was applied to identify specific social network factors that influence the longitudinal change of depression level of the elderly. In the result of the analysis, it was found that initial value of depression of the elderly was influenced by whether they have a spouse or not, number of household member, meeting with close people, whether they do economic activity or not, whether they have a religion or not, etc. and the rate of change in depression of the elderly was influenced by number of household member, meeting with close people, expectation about life, etc. Through above results, this study suggests a need for specific programs and supports to continuously lower the depression level of the elderly.

Methods of contrast enhancement have problem such as side effect of over-enhancement with non-gaussian histogram distribution, tradeoff enhancement efficiency against brightness preserving. In order to enhance contrast at various histogram distribution, segmentation to region with gaussian distribution and then enhance contrast each region. First, we segment an image into several regions using GMM(Gaussian Mixture Model)fitting by that k-mean clustering and EM(Expectation-Maximization) in $L^*a^*b^*$ color space. As a result region segmentation, we get the region map and probability map. Then we apply local contrast enhancement algorithm that mean shift to minimum overlapping of each region and preserve brightness histogram equalization. Experiment result show that proposed region based contrast enhancement method compare to the conventional method as AMBE(AbsoluteMean Brightness Error) and AE(Average Entropy), brightness is maintained and represented detail information.

Giving behavior can be defined to be a behavior intended to benefit the society's charity works and public works via sharing one's financial resources. The determinants of giving behavior largely consist of sociodemographic factors, such as the income, age, gender, religion, education level, residential areas, and tax deduction policy, etc. This paper considers the income level, self-esteem, and perceived responsibility toward social welfare, as the major research variables. Statistical results, based on 2014 Korean Welfare Panel data, show that the income level and self-esteem have positive influence on participation intention in charitable giving. However, welfare responsibility has negative impact on participation intention. Second, household income was the only salient, negative factor for giving efforts defined as the amount of donation over income, implying that the higher income brackets are giving less money relative to their income level, than those with lower income level. Contrary to our expectation, self-esteem and welfare responsibility were not statistically significant explanatory variables.

Impaction of maxillary incisor is rare than the third molar and canine, but its rate is higher than the other anterior teeth due to frequent mesiodens, trauma and variation of root formation (root dilaceration etc.). It is often observed in the dental age of about eight years and over. It will be occurred that the space loss, midline deviation and cyst formation due to the impaction of maxillary incisor. So it is important to evaluate the precise location of impacted tooth and to make appropriate treatment plan. Treatment would be surgical extraction or expectation for spontaneous eruption. If the impacted tooth has no pathologic change and development of the root is favorable, orthodontic traction is recommended for recovery of function and esthetics. In these cases, we performed orthodontic traction for the eruption of impacted maxillary incisors, and obtained satisfactory results.

Aesthetics can be affected by the interest and the trend of the time. There are the limits of the equipment and materials required for the times, aesthetic case is also considered necessary to overcome them and will introduce the following case in accordance with the patients demands and circumstances. I hope the further development of CAD/CAM by taking over the things have done in the analogue by utilizing the latest technology that is thought to challenge the current limit itself is important. Digital has the advantages in various perspectives. Especially, I am very interested in as related to "digital communication." In particular, when utilizing the data using intra oral scanner can easily direct converse about prosthesis between the dentist and the dental technician through a software program Now, as the digital communication affects the integrity of the prosthesis directly, I had a expectation of a new era for the prosthetic and aesthetics. In this case report, I would like to introduce direct and real digital communication through the following 2 parts.

Piezoelectric gyroscopes are the devices to measure angular rotational velocity of a system with respect to an inertial frame of reference means of the Coriolis principle. Most of current piezoelectric gyroscopes detect rotational velocity about a single axis of rotation. This paper describes development of a new dual axial gyroscope made out of the piezoelectric ceramic, PZT, which can overcome the limitation of the current single axial type. The validity of the new structure is checked through finite element analysis. Based on the design, an experimental sample of the sensor is fabricated and its performance is discussed in comparison with the theoretical expectation. The resutls show that the present gyroscope is capable of measuring the rotational velocity over two orthogonal axes simultaneously with good enough sensitivity and distinction between the two axial components of the rotation.
