The purpose of this study was to develop hand creams among the types of cosmetics based on domestic pumpkins grown in Yangju. Pumpkins are mostly used for cooking, but because they contain a large amount of vitamin A, they can also be used as raw materials for cosmetics to prevent skin aging. The final design was researched and developed through a graphic expression of pumpkin characteristics, a design process, and a survey on preference for differentiated packaging design. The survey targets women in their 20s and 30s who directly purchase cosmetics, and an analysis of consumers' preference for brand product decisions showed that simple and modern designs suitable for cosmetics images topped the list. In addition, it showed a positive image of cosmetics development using local agricultural products and high brand value. We present the possibility that domestic pumpkin raw materials can be applied to cosmetics and aim to develop excellent cosmetics brands through consumer preference surveys.

In this paper, we propose a watershed algorithm that applies a high-frequency enhancement filter to emphasize the boundary and a local adaptive threshold to search for minimum points. The previous method causes the problem of over-segmentation, and over- segmentation appears around the boundary of the object, creating an inaccurate boundary of the region. The proposed method applies a high-frequency enhancement filter that emphasizes the high-frequency region while preserving the low-frequency region, and performs a minimum point search to consider local characteristics. When merging regions, a fixed threshold is applied. As a result of the experiment, the proposed method reduced the number of segmented regions by about 58% while preserving the boundaries of the regions compared to when high frequency emphasis filters were not used.

As the importance of Culture Technology (music, publication, mobile, film, video, cartoon, animation, character, game, broadcasting etc) is increased, the field of character industry recently has been recognized as an independent brand value beyond the existing view point of simple designing; it also has been given much attention as a main axis leading the cultural industry of the 21 st century. The character of a local government plays roles such as a symbolic part of a region, parts of tourism and public relations, and a profit-making function, which results into generation of regional image and activation of regional economy. However, the present application strategy of the character is only limited to an early stage of regional advertisements. In this context, this study is aimed to investigate and analyze the character development of local governments, especially 31 cities and goons of Gyeonggi Province, comparing with those of local governments of Japan. In the long run, this will provide some suggestions for strategy of character applications. Then, this research is expected to be used as basic reference materials for character development of other local governments and government agencies.

This study is to identify the effects of hypertension management program at a community health center on the disease-related knowledge, self-efficacy, anthropometric measurements and blood pressure of a hypertensive patient in local community. This study is a quasi-experimental study using nonequivalence control group no-synchronized design in order to verify the effects of the hypertension management program at a community health center on the hypertension-related knowledge, self-efficacy, anthropometric measurements and blood pressure of a hypertensive patient in local community. The result indicated a significant difference between the experimental group and control group in the scores of hypertension-related knowledge (t=-4.25, p<.001), self-efficacy (t=-4.20, p<.001), systolic blood pressure (t=7.70, p<.001) and diastolic blood(t=5.91, p<.001), body weight(t=2.32, p=.026) and abdominal circumference(t=2.17, p=.036). The hypertensive patients' knowledge and self-efficacy were improved, and their weight and abdominal circumference as well as systolic blood pressure and diastolic blood pressure were reduced. Therefore, it was confirmed that multilateral approaches in terms of physical and psychosocial aspects only targeting hypertensive patients were required for managing hypertensive patients in local community.

The local storage method for home cameras, which relies on inserting an SD card into the device to store data, offers a convenient and cost-effective solution, as there are no recurring expenses after purchasing the SD card. However, we recognize that this method comes with significant security challenges. In particular, the ease with which third parties can access the SD card makes it vulnerable to both physical and software tampering. As the acceptance rate of home camera footage as evidence in courts has increased, we have become increasingly aware of the critical nature of these security issues. Digital data from home cameras, unlike other types of physical evidence, can be more easily tampered with and altered. To ensure that such data is recognized as valid legal evidence, we must prove its integrity and demonstrate that it has not been tampered with. In response to these challenges, we are committed to strengthening the security measures for both the home camera device and its local storage. By doing so, we aim to ensure the integrity and reliability of the data, thereby enhancing the overall security and trustworthiness of home camera systems.

Recently, users using social network service(SNS) with smart phone as well as users using smart phone are so rapidly increasing. In this paper, Android based local SNS system is proposed and developed. The main feature and contribution are as follows. First, the proposed SNS system is developed based on smart phone Android for supporting both the search of neighbor users and the addition of friends to start SNS with Web/DB. Second, the system is designed with the unchanged basic UI of Android and user oriented approach. The performance evaluation is performed by using OPTIMUS-Q/ANDROID 2.1. The results of performance evaluation show that the proposed SNS system can efficiently support the neighbor search services by using android based bluetooth neighbor search. Currently, we are still ongoing working on bluetooth autofaring in android to improve the performance of the proposed system.

Wireless Sensor Network is an event-driven system that a large number of micro sensor nodes are collected, giving and Wing information. Congestion can take place easily since a great number of sensor nodes are sensing data and transferring them to sink nodes when an event occurs, comparing to the existing wired network. Current internet transport protocol is TCP/UDP, however, this is not proper for wireless sensor network event-driven ESRT, STCP and CODA are being studied for reliable data transport in the wireless sensor network. Congestion are being detected local buffer and channel loading with these techniques. Broadcasting is mainly used and can avoid congestion when one happens. The way that combining local buffer and channel loading information and detecting congestion is being studied in this paper. When congestion occurs, buffering state is divided into three in order to lessen the broadcasting sending the message on congestion control to the node having frequent channel loading. Thus they have advantage of decreasing network's loading.

Proxy Mobile IPv6 (PMIPv6) has received considerable attention between telecommunications and the Internet communities and does not require active participation of the Mobile Node (MN) by way of network-based mobility management. The PMIPv6 domain is studying establishment in progress to support extensively a number of MN by using a low handover latency. In this research, we are propose a novel 3S scheme for building Scalable and Secure and Seamless PMIPv6 domains. In the proposed scheme, all of Mobility Access Gateway (MAG) are acting as the Local Mobility Anchor (LMA) and composing a virtual ring with another MAG. General hashing is used in the efficient distribution-mapping between each MN and the MN's LMA of all MAGs. And, MAG and MN are authenticated using the symmetric key. Through mathematical analysis, we verifies the safety, scalability, and seamless service for 3S. Also, we're propose a handover procedure of 3S and show better than the existing schemes in terms of handover latency.
