One noticeable thing about the recently opened 'Starfield Hanam' and 'Hyundai Department Store (Pangyo)' is consumer's interest and positive response to their hosted food brands ranging from restaurants, dessert cafes and coffee shops. Department store and shopping complex, so-called aggregation of lifestyle are making the most out of food brands as a differentiation strategy and consumer's interest on it act as a barometer for current consumption trend. Along with the high interest on food market, changes in lifestyle, such as increasing ratio of two or less households, advent of multiple communication channels as SNS, deluge of information and gradually developing individualism, are creating needs for convenient but high quality eating culture. This need contributed in transforming the product family which was once famous as 'Instant Food' into a 'Home Meal Replacement (HMR)'. Since local food companies are striving to keep pace with the trend and actively penetrating HMR market, regardless of long-term recession, the Korean domestic food market is steadily growing with a bright future.

Objectives : Korea's average life expectancy is getting longer and longer and the pace of change in society has increased every year as people experience stress more easily. Under this situation, chronic sleep disorder is increasing, but there is no specific program for the treatment of sleep disorder in Korean medicine. Therefore, we studied a Korean medical treatment program for sleep disorder to apply to outpatient clinic patients. Methods : For this study, we evaluated the Insomnia Severity Index (ISI), BDI, STAI, FSS on 29 insomnia patients who visited Kyunghee Korean medical hospital from July 2010 to May 2012. Herbal medicine, acupuncture, herbal acupuncture, moxibustion, sleep hygiene, and medical qigong were applied. We compared ISI scores before treatment and after 4 weeks of treatment. Results : ISI score was improved after Korean medical treatment for sleep disorder. Before the treatment ISI score was 18.1, which means clinical insomnia. After the Korean medical treatment, the score was 7.5, which means no clinically significant insomnia. Conclusions : The study showed a significant effect on the Korean medical treatment program for sleep disorder to apply to outpatient clinic patients. ISI score was improved and the patients were satisfied with the treatment, so it would be more helpful to apply in sleep clinics.

Recently, the personal cloud computing service has been being spotlighted as an individual tool of productivity enhancement. However, compared to the rosy forecast, its diffusion rate in the domestic (Korean) market is much slower than expected. In order to find the reason for the slow growth of personal cloud computing service, we attempt to identify influencing factors on user's adoption resistance, while most prior research has focused on the factors affecting its adoption. Based on both the person-technology fit model and the privacy calculus model, we propose technostress and perceived value as key antecedents of adoption resistance. In addition, we identify (1) technical (pace of change and complexity) and personal (self-efficacy) influencing factors on technostress, and (2) beneficial (perceived mobility and perceived availability) and harmful (perceived vulnerability) influencing factors on perceived value. To validate our research model, 133 individual samples were gathered from undergraduate and graduate students who had actual experience of using at least one of personal cloud computing services. The results of the structural equation modeling confirm that both technostress and perceived value have significant effects on adoption resistance, but they have different influencing mechanisms to different types of adoption resistance (indifference, postponement, and rejection). Theoretical and practical contributions are discussed in the conclusion.

In response to insurmountable pressure for a broad distribution of political power between the central government and local governments, the Korean Government pushes for the establishment of the local port authority as the optimum choice to achieve its goal. Starting with the Pusan and Incheon ports, the local port authority system is expected to setout the dramatic change in port management system throughout the Korean ports. However, this paper points out that the port reform choice should take into account the specific features of the society and country and some basic questions should be clearly answered beforehand. The fundamental questions are: whether institutional reform will markedly improve the ports managerial and operational efficiencies? and what will be the benefits and costs, compared to those of not changing? Without rigorous and comprehensive analysis on these issues in the institution transition, haphazard port reform will have the possibility to increase port users costs and disrupt the efficient port services. Experiences around the world clearly show that the indiscriminate copy of port reform found in other countries may be neither feasible nor practical presently in Korea. They also indicate that the port reform should be made on a gradual basis with full control of the pace.

Cloud storage is provided as a service in order to keep pace with the increasing use of digital information. It can be used to store data via networks and various devices and is easy to access. Unlike existing removable storage, many users can use cloud storage because it has no storage capacity limit and does not require a storage medium. Cloud storage reliability has become a topic of importance, as many users employ it for saving great volumes of data. For protection against unethical administrators and attackers, a variety of cryptography systems, such as searchable encryption and proxy re-encryption, are being applied to cloud storage systems. However, the existing searchable encryption technology is inconvenient to use in a cloud storage environment where users upload their data. This is because this data is shared with others, as necessary, and the users with whom the data is shared change frequently. In this paper, we propose a searchable re-encryption scheme in which a user can safely share data with others by generating a searchable encryption index and then re-encrypt it.

Recently, uses of a large, wide screen monitors are general, so people that efficiently use work area of monitor is encreasing. Use pattern of monitor is being changed just using one window to many windows at a time. In this paper, I will explain develop windows placement system for efficient use monitor. It is different from other general utility about windows placement system because users can easily change windows placement to use preview window. The future, a large, wide screen monitors to keep pace with the demand to take advantage of the window to satisfy the needs of the user to manually adjust the window to the inconvenience that will be resolved.

We conducted a three-dimensional numerical simulation by using the FLOW-3D, with RANS as the governing equation, in an effort to track the dam-break wave.immediately after a dam break.in areas surrounding where the dam break took place as well as the bed change caused by the dam-break wave. In particular, we computed the bed change in the movable bed and compared the variation in flood wave induced by the bed change with our analysis results in the fixed bed. The analysis results can be summarized as follows: First, the analysis results on the flood wave in the L-shaped channel and on the flood wave and bed change in the movable-bed channel successfully reproduce the findings of the hydraulic experiment. Second, the concentration of suspended sediment is the highest in the front of the flood wave, and the greatest bed change is observed in the direct downstream of the dam where the water flow changes tremendously. Generated in the upstream of the channel, suspended sediment results in erosion and sedimentation alternately in the downstream region. With the arrival of the flood wave, erosion initially prove predominant in the inner side of the L-shaped bend, but over time, it tends to move gradually toward the outer side of the bend. Third, the flood wave in the L-shaped channel with a movable bed propagates at a slower pace than that in the fixed bed due to the erosion and sedimentation of the bed, leading to a remarkable increase in flood water level.

This study predicted urban green spaces for 2020 based on two scenarios keeping or freeing the green-belt in the Daegu metropolitan city using a hybrid Cellular Automata(CA)-Markov model and analyzed the spatial dynamics of urban green spaces between 2009 and 2020 using a land cover change detection technique and spatial metrics. Markov chain analysis was employed to derive the transition probability for projecting land cover change into the future for 2020 based on two land cover maps in 1998 and 2009 provided by the Ministry of Environment. Multi-criteria evaluation(MCE) was adopted to develop seven suitability maps which were empirically derived in relation to the six restriction factors underlying the land cover change between the years 1998 and 2009. A hybrid CA-Markov model was then implemented to predict the land cover change over an 11 year period to 2020 based on two scenarios keeping or freeing the green-belt. The projected land cover for 2009 was cross-validated with the actual land cover in 2009 using Kappa statistics. Results show that urban green spaces will be remarkably fragmented in the suburban areas such as Dalseong-gun, Seongseo, Ansim and Chilgok in the year 2020 if the Daegu metropolitan city keeps its urbanization at current pace and in case of keeping the green-belt. In case of freeing the green-belt, urban green spaces will be fragmented on the fringes of the green-belt. It is thus required to monitor urban green spaces systematically considering the spatial change patterns identified by this study for sustainably managing them in the Daegu metropolitan city in the near future.

The current formal and memorized design repetition training and practice is wandering in the uniform flat design thinking expression. To change these two-dimensional current issues into a three-dimensional design method, set the direction for each grade level under the integrated convergence educational goal and carry out projects step by step to understand design, the principle of spatial composition, the introduction of traditional design history, and the overall design of craft design. Creative and practical skills such as approach should be cultivated. Designers can only be produced through systematic education and training. In order to lead society and succeed, a designer who has experienced solutions and countermeasures on how to adapt themselves to the demands of various changes in the times must come to the field. Education experts insisted on innovation of the organizational structure and subject of the education system, and emphasized the importance of education in response to the rapid pace of change in the 21st century. This study aims to propose an educational system that combines academic research with a structural approach to tasks by setting a project that reflects the needs of society for convergence practice in which design and adjacent disciplines are linked through understanding and analysis of these issues.

In the past society, it was possible for parents to provide career guidance at home and career education without professional education courses and knowledge about career education at school since the simple job and the slow pace of social change. However, in modern society, the profession itself becomes complicated, and professional functions and knowledge are required in the profession, and the job world is changed and also a lot of jobs will disappear. This change has made it difficult to establish the value of work and then career education has become very important and urgent. In this paper we develop a career education app for elementary school students and then examine the pedagogical effect of career education app on career education. We applied our proposed course to an elementary school in Seoul. In the course, totally eight hours of classes were offered to the 5-6th graders of an elementary class. As a result, students who took part in the class have a better understanding of the job and also the satisfaction level of the course was also very high.
