This study investigated the purchase intention of green fashion products based on Rogers' Diffusion of Innovation theory and compared the differences between Korean and British consumers. In order to identify the impact of personal characteristics, this study also examined the effects of fashion innovativeness and LOHAS tendency on perceived attributes of innovation and intention to purchase. With a convenience sampling method, a survey questionnaire was distributed at popular fashion streets in each country. A total of 426 data were obtained, 203 from the UK and 223 from Korea. About 52% were females, and 69% were in their twenties. A factor analysis generated two LOHAS factors (health concerns and eco concerns) and four attributes of green fashion products (image improvement, symbolic superiority, observability, and compatibility). Two types of green fashion products (organic cotton t-shirts and organic cotton t-shirts with an environmental message) were provided to measure the purchase intention, respectively. The findings were as follows. British consumers were more likely to show LOHAS tendency and to perceive positive advantages of green products compared to Koreans; in addition, British consumers presented higher mean scores on the purchase intentions of organic cotton products. Fashion innovativeness was significant to predict image improvement and symbolic superiority, while eco concerns were significant in compatibility for both nations. Compatibility was important for both countries in order to explain the intention to adopt two types of organic products. In addition, image improvement was another predictor for purchase intention of organic t-shirts with an environmental message. Managerial implications were provided.

To identify the cause of the error and maintain the health of system, an administrator usually analyzes event log data since it contains useful information to infer the cause of the error. However, because today's systems are huge and complex, it is almost impossible for administrators to manually analyze event log files to identify the cause of an error. In particular, as OpenStack, which is being widely used as cloud management system, operates with various service modules being linked to multiple servers, it is hard to access each node and analyze event log messages for each service module in the case of an error. For this, in this paper, we propose a novel message-based log analysis method that enables the administrator to find the cause of an error quickly. Specifically, the proposed method 1) consolidates event log data generated from system level and application service level, 2) clusters the consolidated data based on messages, and 3) analyzes interrelations among message groups in order to promptly identify the cause of a system error. This study has great significance in the following three aspects. First, the root cause of the error can be identified by collecting event logs of both system level and application service level and analyzing interrelations among the logs. Second, administrators do not need to classify messages for training since unsupervised learning of event log messages is applied. Third, using Dynamic Time Warping, an algorithm for measuring similarity of dynamic patterns over time increases accuracy of analysis on patterns generated from distributed system in which time synchronization is not exactly consistent.

In the process of vaccine delivery and vaccination, temperature is mostly controlled by an insulated containers containing ice. Moreover, amount of wasted vaccine is significant because the temperature of the vaccine is not properly controlled. A core challenge of vaccination is temperature data monitoring, since it is critical for managing and operating strategical vaccination by health organizations. In this research, a real-time monitoring vaccine carrier system was developed. Temperature, location, and power consumption data of the vaccine carrier were monitored and working performances of the vaccine carrier were tested in both Korea and Tanzania (Arusha and Kilimanjaro regions). For both places, Short Message Service (SMS) communication method was used to send information of the carrier's status. As a result, the monitoring system was able to transmit and receive real-time data of the vaccine carrier status while the vaccine carrier was tested. The vaccine status data can be accessed from any location through the cloud server and web-based user interface.

The purpose of this study is to provide basic data for school health computerization by investigating the nurse teacher's attitudes toward school health computerization. For this study, the questionnaires were given to 559 nurse teachers from 3. March to 17. March, 1995. Among them, 338 were returned and included for the analysis. The results of the study were as follows : 1. In general characteristics, the results showed average of 38.6 years in age ; and average of 11.1 years in education experience. In distribution of school, the result showed 47.0% in elementary school, 30.5% in middle school and 22.5% in high school ; 75.4% national and public school vs 26.4% private school. 2. In attitudes of computerization, the score was varied from 19 to 76 point. The attitudes was generally positive with the average of 60.23±7.63(SD) score. The respondents are willing to participate in computer education(the highest score, 3.69), they worry about electromagnetic waves by computer (the lowest score : 2.30). 3. 92.6％ of the respondents want to participate in computer education. The major reason the respondents have not yet learned computer is that they had little chance to learn. While 58.0% of them answered that they had an experience of computer use in school health works, few schools had computer in dispensary. In computer use, nurse teachers in public school have more experience than ones in private school. Word processing was the major function that the most respondents can do(62.7%). They answered that they have little knowledge of computer (84.0%). 4. Computer can be utilized in school health works as follows in order : message from school to home, reports, annual plan and statistics. 65.4% of them answered that computer can be used in 10 items of 13 items. 5. The attitudes of computerization showed differences in the following variables career, age, existence of computer in school health clinic, experience of computer use, intention to participate in computer education, computer knowledge, frequent computer use, ability of computer use, school health computerization areas, experience of computer education. Among there variables, age, existence of computer in school health clinic, intention to participate in computer education, ability of computer use, school health computerization areas showed significant explanation(28.3%) for the attitudes of computerization in multiple regression analysis The younger. the higher degree of intention, the more functions they can perform, the more school health computerization areas, and the more computers in school health clinic, the more positive attitude on school health computerization. In conclusion, to achieve the successful computerization of school health works, the positive attitudes of nurse teachers should be encourged for school health computerization. For this purpose, the chance of computer education should be given as many times as possible. And administerial as well as financial support are essential for enlarging the knowledge and ability of computer.

The sensor network is a key component of the ubiquitous computing system which is expected to be widely utilized in logistics control, environment/disaster control, medical/health-care services, digital home and other applications. Nodes in the sensor network are small-sized and exposed to adverse environments. They are demanded to perform their missions with very limited power supply only. Also the sensor network is composed of much more nodes than the wireless ad hoc networks are. In case that some nodes consume up their power capacity, the network topology should change, and rerouting/retransmission is necessitated. Communication protocols studied for conventional wireless networks or ad hoc networks are not suited for the sensor network resultantly. Schemes should be devised to control the efficient usage of node power in the sensor network. This paper proposes a medium access protocol to enhance the efficiency of energy consumption in the sensor network node. Its performance is analyzed by simulation.

As smart phone became popular, its excessive uses cause adverse effects called smart-phone syndrome such as Turtle-neck syndrome in physical side and smart-phone addiction in mental aspects. Turtle-neck syndrome incurred by incorrect posture when you watch smart-phone, which causes a serious health problems. However, these syndromes can be detected by gyro-sensor and timer, and prevented by correcting the posture and halting the function with smart-phone application (App). Thus, this paper proposes App that helps user to realize bad posture and addiction to smart-phone, and to acquire the correct habit by inducing user to stretch neck or to stop operation with warning message. If we tried to adjust bad posture and addiction in using smart-phone through this application, the social losses from smart-phone syndrome would be minimized as a result.
