As the society has become maturer, stress has emerged as a hot social issue. In this paper, we proposed the design and implementation of a customized contents service system for relieving users' stress. In the proposed system, we compute the stress index from a user's biometics and psychology, and recommend a combination of video, sound, aroma, and lighting based on the index and user's data such as preferences, and provide the recommended contents service. We first classify symptoms of stress and then define a tool for self assessment. We classify video, sound, aroma, and lighting contents as well according to the defined symptoms. We propose 3-phase customized recommender and service model for customized contents service. We design and implement a customized contents service system for relieving users' stress. Different from existing systems, this proposed system has an individually-customized system and provides a diverse combination of different content's types.

Purpose: The purpose of this study was to develop the adapted standard items of situation, background, assessment, recommendations (SBAR) processing for handover between nursing units in Korean hospitals and evaluate the validity and relevance of the standard items. Methods: A delphi method with 33 experts was used to evaluate content validity of the standard items. Then, 1,175 nurses working in general hospitals of more than 500 beds were recruited to evaluate the validity and relevance of the standard items for clinical implication. Results: Content validity was higher than 0.8. The highest scores for relevance among items in handover standards were state of consciousness in the assessment domain for a ward to a ward transfer ($3.82{\pm}0.40$), for a ward to an ICU ($3.85{\pm}0.38$), an ICU to a ward ($3.81{\pm}0.39$) and an ER to a ward ($3.85{\pm}0.37$). Congenital malformation was the highest relevance score for handover from a delivery room to a neonatal unit ($3.91{\pm}0.30$). Conclusion: This study evaluated validity and relevance of the essential contents for handover standards between units to improve communication quality among nurses. The findings of this study should also be applied in clinical nursing areas and the quality of information and effectiveness of usage of the standard should be evaluated.

The purpose of this study was to examine the reaction in variable light environments on shade tolerant species, Chloranthus glaber. We raised Chloranthus glaber seedlings under four light conditions: PPFD 400, 250, $100\;{\mu}mol\;m^{-2}s^{-1}$ and full sunlight (PPFD $1600\;{\mu}mol\;m^{-2}s^{-1}$). Using 2 years old seedlings, chlorophyll content, photosynthetic rate, stomata conductance and intercellular $CO_2$ concentration were investigated. Shaded seedlings had higher chlorophyll content, photosynthetic rates, and stomatal conductance, but not higher intercellular $CO_2$ concentration than those in the full sun treatment. This result suggested that growth and physiology of Chloranthus glaber adapted to low light intensity.

Wireless multicast service can be used for video streaming service to save the network resources by sending the same popular multimedia contents to a group of users at once. For better multimedia streaming multicast service, we propose a quality-aware rate adaptation (QARA) scheme for scalable video multicast in rate adaptive wireless networks. In QARA, transmission rate is determined depending on the content's type and users' channel conditions. First, the base layer is transmitted by a low rate for high reliability. That means we provide basic service quality to all users. On the contrary, the transmission rate for enhancement layer is adapted by using channel condition feedback from a randomly selected node. So, the enhancement layer frames in a multimedia content is sent with various transmission rates. Therefore, each node can be provided with differentiated quality services. Consequently, QARA is capable of serving heterogeneous population of mobile nodes. Moreover, it can utilize network resources more efficiently. Our simulation results show that QARA outperforms utilization of the available transmission rate and reduces the data transmission time.

This study aims to development and validation a tool to measure physical education teaching anxiety(PETA) among preservice special teacher. In order to achieve this study purpose, first, the preliminary items for measurement scale were collected through open-ended questions and were developed by inductive content analysis from the 100 preservice special teacher. Second, investigation for construct validity was conducted on exploratory factor analysis from the 100 preservice special teacher. Third, in the final process, verify exernal validity was conducted by confirmatory factor analysis and t-test from the 300 presevice special teacher. As a result, the measurement scale of physical education teaching anxiety(PETA) among preservice special teacher consists of 4 main factors with 14 items: pedagogical content knowledge(n=4), understanding students(n=4), class environment(n=3), class management(n=3) factors and this scale has enough suitability.

The paper aims to improve the quality and validity of community plan using the content analysis on gyeongju-si. To achieve it, the relevant literatures reviewed, and established the basic framework and three criteria of community plan, then adapted these criteria to the gyeongju-si community plan. Findings are like: Firstly, the measurement criteria of validity are clarified into three; vertical consistency on the whole plan's hierarchical structure, horizontal relevancy between the section plans, clearness of statement. Secondly, generally, gyeongju si plan didn't satisfy the criteria of validity. Based on these results, it specifically offers a impoverishment strategy including the guidelines' upgrading.

The validity of the hypothesis that between-breed differences of carcass composition in cattle can be reduced when compared at the same degree of maturity was assessed using carcass data of various breeds obtained from slaughter experiments in Denmark, Japan and Malaysia. All cattle were kept in intensive feeding conditions in this study. With respect to temperate data (Danish and Japanese data), although large between-breed differences were found in carcass composition in the comparison at the same slaughter weight, the differences were reduced when compared at the same degree of maturity. This result supported the above hypothesis. Kedah-Kelantan and their crosses in Malaysian data, however, had more muscle and bone contents but less fat content than temperate breeds, even if compared at the same degree of maturity. This could be attributed to the history that native Kedah-Kelantan breed has adapted itself in the direction of decreasing fat deposition which requires much energy and prevents heat evaporation, in order to survive under high temperature and high humiodity conditions in Malaysia. In spite of the same tropical breed, carcass composition of Sahiwal-Friesian was similar to that of other temperate breeds at the same degree of maturity.

Internet-based distribution of digital contents provides great opportunities for producers, distributors and consumers, but it may seriously threaten users' privacy. The Digital Rights Management (DRM) systems which one of the major issues, concern the protection of the ownership/copyright of digital content. However, the most recent DRM systems do not support the protection of the user's personal information. This paper examines the lack of privacy in DRM systems. We describe a privacy policy and user's privacy preferences model that protect each user's personal information from privacy violation by DRM systems. We allow DRM privacy agent to automatically negotiate between the DRM system policy and user's privacy preferences to be disclosed on behalf of the user. We propose an effective negotiation algorithm for the DRM system. Privacy rules are created following the negotiation process to control access of the user's personal information in the DRM system. The proposed privacy negotiation algorithm can be adapted appropriately to the existing DRM systems to solve the privacy problem effectively.

The trend of making film from the comic source, which is a prototype of so-called media mix, is indeed a different phenomenon from the traditional ones from novel or play sources. Historically comics are recently adapted to film although they have narratives and continuity of images. It is due to the lack of social conception of comics genre and extension of imagination that is a characteristics of the comics. However, it is conspicuous that comics has been a source of film along with the development of technology of visual image reproduction and the trend of enlarging reproduction of popular media image. Since comics can provide narratives and he visual sense for film making, these trend will be continued and more vivid.

Recently, the Social Internet of Things (IoT), the follow-up of the IoT, has been studied to expand the existing IoT services, by integrating devices into the social network of people. In the Social IoT environment, humans, devices and digital contents are connected with social relationships, to guarantee the network navigability and establish levels of trustworthiness. However, this environment handles massive data, including social data of humans (e.g., profile, interest and relationship), profiles of IoT devices, and digital contents. Hence, users and service providers in the Social IoT are exposed to arbitrary data when searching for specific information. A study about the recommender system for the Social IoT environment is therefore needed, to provide the required information only. In this paper, we propose the Social correlation group based Recommender System (SRS). The SRS generates a target group, depending on the social correlation of the service requirement. To generate the target group, we have designed an architecture, and proposed a procedure of the SRS based on features of social interest similarity and principles of the Collaborative Filtering and the Content-based Recommender System. With simulation results of the target scenario, we present the possibility of the SRS to be adapted to various Social IoT services.
