In the field conservation treatment, it is important that the method chosen to lift an object out of the ground depends on its surrounding weather, strength, size, composition, and condition. This paper describes a physical support(Urethane bandage, De naturation - polyisoprene resin) created for lifting delicate relics in this field. The advantage of Urethane bandage method is of conveniently portable size, and it's convenient for use, while curing time is very fast.(approx. 5~10minute)Denaturation -polyisoprene resin is able to be soft by the hot water(approx. $60^{\circ}C$ ). so it's good to stick to the relic surface of an indeterminate form. The results of use of these reinforcement methods are of utility value.

Increase of use of mobile devices results in development of mobile application in various sectors and it has significant influence on our daily life since those devices make our life more convenient and provide various kinds of information. This paper suggests a mobile application design to identify a situation by using Android operating system and Near Field Communication(NFC). This system designs a function to verify student identity based on NFC to support various services for increased objects through tags and applies this function to the mobile attendance management system.

A home-based rehabilitation system for patients with uncomfortable hands or arms was developed. By using this system, patients can save time and money of going to the hospital. The system's interface is easy to manipulate. In this paper, we discuss a rehabilitation system using video recognition; the focus is on designing a convenient user interface and rehabilitation training methods. The system consists of two screens: one for recording user's information and the other for training. A first-time user inputs his/her information. The system chooses the training method based on the information and records the training process automatically using video recognition. On the training screen, video clips of the training method and help messages are displayed for the user.

This study was conducted to develop the Apartment Information System. This integrated information system is designed to provide a large number of users with the convenient, economical, and safe life in the apartment complex. The characteristics of this system are as follows; 1) The system was developed by CAD technology using 2D and 3D methods with Web base. 2) This system has 2-Tire structures which are able to embody the geographic information on the Web base without special Spatial Engine. 3) Since the spatial data applied to this system is a vector file format, the speed of electrical transmission is fast and it makes possible to search spatially for the client method. The results of this study may contribute to make use of the information system for apartment complex as follows; 1) This system can be used together by the communities of apartment residence, maintenance company and construction company. 2) Also this system can help residence to communicate sharing information and can support the apartment management with open information and clarity. Expecially, the practical data gathering was made for this study only.

This paper reports on the development of the analysis program of the piston skirt system, PS-LAP. It is essential to verify the stability of the design and to improve the performance of the system. In order to do that efficiently, it is required that integrated and interactive simulation analysis program. PS-LAP is developed in the base of the object-oriented, capsulation, modulization, OLE(objected linking and embedding) and variational design theory. So it contain the expandability and flexibility of the structure. In addition to that, it is programed to make the convenient user interface by using the visualization programming. It can support the modification of the piston skirt shape, lubrication condition and so on. It is expected to reduce the money and effort for design the piston skirt system.

With the proliferation of EC, many customers have been participating into online auction or group-buying market over searching internet shopping-malls to purchase goods. To support the customer's convenient transaction, lots of agent systems are developed to facilitate the customer's product brokering, merchant brokering, and negotiation of transaction. However, many of these systems have focused upon supporting transaction at only one type of marketplace. Since these marketplaces have different transaction settlement mechanism, it is necessary to develop the system that utilizes the customer's transaction including the selection of the type of marketplace to buy. Then we classify the kinds of B2C electronic marketplace according to the protocol by which the market operated. The structure of negotiation message is developed using XML schema and RDFS under the characteristics and message example of each marketplace in this research.

In this paper, we use scratch to design and develop non-formal learning experiences that are linked with contents of secondary science textbook to educational programs. The goal of this paper is to develop a convenient and interesting program for non-formal learning in a learning environment using various smart device. Theoretical approaches to mobile education, such as smartphones, and smart education support policies continue to lead to various research efforts. Although most of the smart education systems developed for students who have difficulty in academic performance are utilized, they are limited to general students. To solve the problem, the learning environment was implanted by combining the scratch, which is an educational programming that can be easily written. The science education program proposed in this paper shows the result of process of programming using ICT device using scratch programming. In the evaluation stage, we were able to display the creations and evaluate each other, so that we could refine them more by sharing the completed ideas.

As well-known, fuzzy control has been recognized to be of great usefulness in many engineering fields. However, the present design methods of fuzzy control systems depend on trial and error the thing that limits its usefulness. Therefore, an effective and convenient support tools for design and evaluation are greatly needed as well as the establishment of the design methods and guidling. From these backgrounds, we have developed a fuzzy control simulator[1, 2] which has various fuzzy control methods such as "direct method", "indirect method" and "fuzzy-PID method". This paper deals especially with the "direct method" function of the simulator. The simulator was developed for personal computers and programed in C language.

The history of animals raised by humans began in prehistoric times, and in modern times they were classified as livestock and pets. As social awareness changes, the term 'companion animal' is used instead of 'pet', and related content has also become more diverse. Recently, digital contents such as virtual pet training, memorial space, and AI health diagnosis using metaverse and AI technology are developing. Developed digital content makes pet care convenient and provide emotional support and economic benefits to users. As technology develops and content becomes more diverse, the relationship between pets and humans will become closer in the future, and related laws and ethical guidelines will need to be established.

Purpose: This study was undertaken to explore sex differences in the risk markers of cardiovascular disease (CVD) and psychosocial factors and the relationships among these variables for the community-residing adults. Methods: A cross-sectional study was conducted with a total of 114 participants consisting of 65 men aged 42.85 years old and 49 women aged 46.86 years old. Participants were selected by a convenient sampling of at community cultural centers and churches. They completed a structured questionnaire including demographic characteristics, physiologic risk markers of CVD; lifestyle factors; and depression, social support, and stress. Results: The male participants showed significantly higher systolic and diastolic blood pressures than their counterparts. Significantly higher percent of women were currently non-smokers, and practiced moderate alcohol intake, physical activity, and low fat diet. Among women, the higher the scores of depression and stress were and the lower that of the social support was, the higher blood pressure, waist circumference and BMI were. Among men, those who were less depressed and with higher scores of social support had more physical activity. Conclusion: The findings suggest further studies to explore sex differences of CVD risk markers and psychosocial factors, and their relationships in a larger sample, and to find the mechanism underlying these differences with a prospective design.
