The contents of reef container face a risk of being damaged if the interior temperature and certain maintenance conditions for the shipments cannot be met. Currently, the temperature and other conditions within a reefer container is checked manually and periodically by someone in charge of it. Since it means that there is no real-time checking of the conditions, if something goes wrong, there is no immediate means of correcting the problem. This paper introduces reefer container monitoring system, that checks interior temperature of container on real-time by sensor nodes attaching reefer container using wireless sensor network. It senses the temperature, amount of light, motion and the change in speed of the objects that distributes sensors throughout the desired places and sends the data wirelessly to anyone interested. Because the prosed technique can check the temperature and other conditions within a reefer container on real-time basis, it enables efficient and effective maintenance of temperature and other conditions

This study attempted to research the local food of various regions at a personal level by discovering how food has developed das part of a region's culture base. Discovery of the characteristic story behind the making of a region's characteristic food as local delicacies can inspire self-esteem in the culture, and enhance the real-life image as appropriate to a region, and thereby be made a part of local tourism and thus contributing to the local economy. For this reason, the native foods of the region of Chungcheongnam-do were researched in terms of the cultural sensibilities that inform the unique history of that region. The study was designed so as to aid in understanding food's characteristic value in Chungcheongnam-do and to give a historical representation of Chungcheongnam-do's image by means of storytelling techniques; thus, the local food's character can be presented alongside a story that appeals to the five senses. For this purpose, Chungcheongnam-do's representative native rice table was cast as the 'Hyunchoong rice meal table' - after the figure of admiral Yi Sun Shin of Asan area region, a representative image of Chungcheongnam-do - and 'Choosa rice meal table', after the figure of 'Choosa' Kim Jeong Hee of Yesan region, of which various literary works form a representative image of Chungcheongnam-do. 'Hyunchoong rice meal table' was composed of a health food centered menu which could supply sufficient nutrition as a food ration in times of war or winter shortage, thus providing an image of nutrition and power as appropriate to these situations. Also, to assess the health effectiveness of each rice table, the functionality of the ingredients were investigated as reported in 'Sik-ryo-chan-yo : a dietary treatment' which was published by Soon-Ui Cheon in the Chosun era and by which the foods of the early Chosun era won recognition as being both healthy profitable.

Despite the advancement of knowledge and techniques, architectural design has been developed by similar method and science as the logical tool since the development of Le Corbusier's 'module'. However, in the new millenium emotional design has become a key issue and today is the turning point regarding new method for designing human space. While architecture discipline of the West focused on logic, Japan based its origin in eastern discipline has developed a unique design concept called 'metabolism' and advanced it very effectively. Since its development of the unique concept, Toyo Ito has become one of the most Influential architect in and out of Japan who devoted his design career in developing new space concept. This study is specifically focused on Ito's project by finding characteristics of his projects and analyze emotional design factors by using 5 analytical tool - experiencing the space, five senses, landmark, sequence, and scale. Ito's work between 2000-2004, such as Sendai Mediatheque, showed more visible sign of emotional design characteristics compared to the works done in 1990's. Because of the analytical studies researching those emotional design characteristics and methods, the future advancement in new space design will be possible with great success. The result proves that continuing proper analysis and research in design method will assist in approaching new space design method into more advanced realm in very efficient time period with more definite design elements to accomodate and fulfill human needs in given space.

Patients with dementia or elderly patients who can not move at all by themselves are at a high risk of falls and bedsore due to lack of caregivers. In this paper, to solve this problem, we propose an algorithm to determine the patient's lying postures by discriminating the main body parts such as head, shoulders, and hips based on the pressure intensity sensed at regular intervals. A smart mat with a lattice structure in which a pressure sensor is arranged so that the body part can be discriminated irrespective of the physical characteristics has been implemented. It consists of two modules of $7{\times}7$ array size. Each module consists of 49 FSR-406 sensors and independently senses pressure. For each module, the body part corresponding to the upper body or the lower body is sequentially discriminated by using a pressure distribution such as a cumulative pressure sum using a filter. The proposed algorithm can identify five lying positions by examining the inclusion relationship between body parts belonging to layer-1 such as head, shoulder, and hip area.

Recently, interdisciplinary studies have been receiving attention. Interdisciplinary research, especially in arts and technology, is a very interesting issue. E.A.T. was founded in New York in 1966 by artists and engineers. Based on the E.A.T. case, this study analyzed the period background in which art and technology could be converged, and the characteristics of E.A.T. works. The analysis results of the period background revealed that five factors influenced the organization and development of E.A.T.. Economic factors, artistic factors, technical factors, educational factors, and sponsored cultural factors influenced the convergence of art and technology. E.A.T. works collaborated by artists and engineers generally had three characteristics. Convergence across various fields, multi-sensitivity utilizing different senses, and interaction between the environment and humans appeared in E.A.T. works. This study provides meaningful implications for both artists and engineers who wish to overcome the limitations of artistic expression and develop new technology.

To information on the inheriance of heading date of rice under the short-day condition, the $F_2$ seeds obtained from all possible combinations of the diallel crosses between five leading rice varieties: Nongbaek, Tongil, Palgueng, Mangyeong and Gimmaze were grown under the short-day condition and natural condition. The days to heading were investigated and analysed for genetic components. The results obtained are summarized as follows. 1. Under the natural condition, the durations to heading of all combinations excluding Nong-baek x Palgueng and Nongbaek x Mangyeong were longer than those of their parents. mean. Whereas, under the short-day condition, the duration to heading of Mangyeong x Gimmaze combination was equal to that of their parents mean, and those of all other combinations were significantly shorter than those of their parents mean. 2. Under the natural condition, the non-allelic gene interactions were significant in days to heading, but under the short-day condition, the non-allelic gene interactions were not significant, and inheritance of days to heading revealed partial dominace in which additive effects were greater than dominant effects. 3. Tongil and Gimmaze were located on dominant zone under the natural day-length, and Nongbaek and Mangyeong were under the short-day condition. 4. Under the natual condition, dominant effects were greater than additive effects, and both heritabilities of the broad and the narrow senses were significantly low. Under the short-day condition, additive effects were significantly higher than dominant effects, and both heritabilities of the broad and the narrow senses were high.

This paper is a study of a rain sensor using an open-ended coaxial cavity resonator which senses the amount of rain drops linearly. It shows that it will be used as a sensor to sense the amount of rain dropped on the windshield of an automobile based on the principle of varied resonant frequency and the loss according to the amount and characteristics of an dielectric lied on the open side of a resonator. The input and output ports are built in the both sides of the resonator and the input and output coupling probes are formed like 'ㄱ' shape. The response of rain drops were simulated by the radius of inner conductor of 2 mm, 5 mm, and 10 mm respectively and it showed that the raindrop was sensed most linearly and sensitively when the radius of inner conductor is 5 mm, We have measured that the resonant frequency have varied from 3.55 GHz to 3 GHz and the Q value have varied from 42.38 to 24.3 according to the variation of rain drop amount on the fabricated resonator. Therefore, it shows that the designed resonator can be applied as a rain sensor that measures the amount of rain drops linearly by using the resonant frequency as a measurement parameter.

The concept of food coordination was introduced at the end of the 1990s and has generated a great deal of interest until now. However, no standard for the classification of such studies has been established yet. This study was conducted to examine the trends in food coordination studies published from 2000 to 2008. To accomplish this, approximately 335 food coordination articles were reviewed. Classification based on content analysis and the document review were conducted based on study themes(subjects), study forms, study designs, places of application, survey area and sample types. The most important type of study identified in this review was study themes. The themes of the study were divided into the following 10 subjects: 1) studies on the definition and recognition of food coordination, 2) studies on the environment, 3) studies on colors and package designs, 4) studies on table setting, table manner and etiquette, 5) studies on photography, editorial design, identity design and menu, 6) studies on components of dining atmosphere display and table/glass ware, 7) studies on emotions and sensibility, the five senses and food coordination, 8) studies on human resources, 9) studies on reviews, food & culture and education, 10) studies on purchasing, consumer behavior and marketing. The most common subjects were the components of dining atmosphere display and table/glass ware(23.6%). In addition, 17% of the articles reviewed were conducted to study colors and package designs, 14.6% to evaluate purchasing and consumer behavior and marketing, 13.4% to evaluate the environment, and 9.6% to study food & culture and education. Overall, these five subjects accounted for more than 75% of the articles reviewed.
