Developing rice endosperm cells display two morphologically distinct rough endoplasmic reticulum (ER) membranes, the cisternae ER (C-ER) and theprotein body ER (PB-ER), the latter delimiting the prolamine protein bodies. We (Li et al., 1993) have recently shown that the storage protein mRNAs are not randomly distributed on these ER types; the C-ER is enriched for glutelin mRNAs, whereas the PB-ER harbors predominantly prolamine transcripts. To address whether these ER types have differnet capacities to translate these mRNAs and translocate their proteins into the lumen, a microsomal fraction enriched in C-ER vesicles was prepared from devleoping rice seeds. When present in an in vitro translatin system, the microsomes were able to proteolytically remove the signal peptide and internalize both preproglutelin and preprolamine within the microsomal vesicles. Of the two species, preprolamine was more effectively translocated and processed. These results suggest that the C-ER has the capacity to recognize and bind both storage protein mRNAs during protein synthesis. Moreover, efficient translocation and processing of glutelin requires additional factors that are deficient or absent in the in vitro system.

This paper presents a method which can recognized the Handwritten Korean characters by using a Context-Free Grammar. The input characters are thinned in order to dwindle the mount of data, the thinned characters are converted into one-dimension strings according to six-forms. when the point of contact among phonemes is found, two phonemes are seperated respectively by marking the index mark (\) at the points. The Context-Free Grammar to input characters is classified into group grammars concerning the similarity of phonemes, input characters are parsed by making use of the Pushdown automata method. As the bent parts in the Handwritten characters are found frequently, We try to correct the bent parts by using the parsing distance measure, which recognize characters according to minium value caused by measuring the weight distance between two sentences. In this experiment, the recognition rate shows 93.8% to 275 Handwritten Korean characters.

This paper proposes an efficient method for recognizing the fingerprint using the extracted features by adaptive principal component analysis(PCA). The adaptive PCA is implemented by a single-layer neural network for extracting the linear features of fingerprint data. And, the extracted data are transformed into binary data for reducing storage space and transmission time. The proposed method has been applied to recognize the 100 fingerprint data. The simulation results show that the recognitions are all successful and capable of about ${\pm}8^{\circ}$ rotated data.

Technology for emotion recognition is an essential part of human personality analysis. To define human personality characteristics, the existing method used the survey method. However, there are many cases where communication cannot make without considering emotions. Hence, emotional recognition technology is an essential element for communication but has also been adopted in many other fields. A person's emotions are revealed in various ways, typically including facial, speech, and biometric responses. Therefore, various methods can recognize emotions, e.g., images, voice signals, and physiological signals. Physiological signals are measured with biological sensors and analyzed to identify emotions. This study employed two sensor types. First, the existing method, the binary arousal-valence method, was subdivided into four levels to classify emotions in more detail. Then, based on the current techniques classified as High/Low, the model was further subdivided into multi-levels. Finally, signal characteristics were extracted using a 1-D Convolution Neural Network (CNN) and classified sixteen feelings. Although CNN was used to learn images in 2D, sensor data in 1D was used as the input in this paper. Finally, the proposed emotional recognition system was evaluated by measuring actual sensors.

This study aimed to determine whether there is a significant difference in play properties in the case of media conversion through the combination of analog three-dimensional puzzles and immersive media in children's experience. Based on Roger Caillois' play theory and the contents of previous research, an experience was conducted on an experimental group and control group, and a questionnaire was prepared. The results of the correlation and paired t-test analysis showed that the play properties were higher and more evenly distributed in the media conversion immersive experience. This implies that an increase in children's fun during the immersive experience further increases their immersion, suggesting that the use of immersive media may have a positive effect on children who achieve holistic development through play and experience. We hope that this study will help recognize the difference in effectiveness through conversion into immersive media and will be referenced in various media studies that consider double-play properties.

This study is aimed to identify the expression and the sense of time in contemporary architectural space. And to classify the system and elements of Zeitlichkeit in the contemporary architectural design. The concept of time can be divided into two meaningful perceptions. Those are the concept of realistic time and the concept of subjective time. These tendencies of theories of architectural space has borrowed from innovations in the sciences, and the whole idea of space-time within art and architecture. Those notions developed through the researches of Bauhaus, Postmodernism, Landscape architecture, Digital Architecture and so forth. The result of this study is that the concepts of time are one of the most important strategies of architectural design and have the various languages which there was not in the past. At the point of the transformation in contemporary architecture, the The concepts of space-time are classified into those from the orders of form and space, from dynamic of the image in the dissolution of architectural form, from traces and steps of movement in dynamic form, and from the systems of commands in the digital softwares. As such, Zeitlichkeit in contemporary architecture means that the architecture moves from the construction of the sensual design elements into Art of life through events and contents which human can experience and recognize. These theories and researches reveal that contemporary architectural movements insert the meaningful stories into architectural space through programs and diagrams.

The purpose of this study is to grasp the nature of health behavior to pactice in order to keep and improve the optimal health in the current status of the cancer patients. The subjects were 21 cancer patients, who knew about their disease for themselves, could communicate without mental disease history, and could understand the purpose of this study and cooperate, in a university hospital in Seoul. The data were collected by direct interview from July 15 to Oct. 17, 1994. The interview took about 1~2hours per one time for each paitent by unstructural and open questions. And they were classified into some similar contents on the basis of the phenomenological analysis and categorized. The analyzed results are as follows: 1) In the daily life before and after diagnosis as cancer patients, they were categorized into 6 areas-the state of movement, sleeping, nutrition and diet, society and economy, drinking and somking, and recognition of their health. 2) In the experience of health behavior of cancer patents, they were categorized into 7 areas-the state of movement, sleeping, nutrition and diet, society and economy, drinking and smoking, recognition of their health, and psychology etc. According to the analyzed results of daily life before diagnosis as cancer patients, it turned out that they didn't recognize the problems for their health habit and made their disease state bad by irresolute characteristics which hesitated to practice rightly, renunciation, and irresponsibility and so on, even if they had much interests in their health and were motivated. Therefore, it is necessary to recognize and have an individual-centric interests in order to change the pattern of life for optimal health state to some extent. In the health behavior of cancer patients, it turned out that they had interests in the state of nutrition and diet the most. Even though they experienced the change of serious nutritive state due to the bad gastroenteric trouble by anticancer treatment, they were trying to have a regular eating habit refraining from irritant food and use folk remedies or healthy food temperating the taste food thoroughly, they also showed the sensitive response for nutrition. In addition, they appeared to use the traditional medical treatment or the folk remedies very seriously without abuse. In consideration of it, it is desirable to use them together with the modern medical treatment intercomplementarily and necessary to look into the types for cancer patients and their benefits.

The purposes of this study were to arrange and analyze the Oriental Mode in 20th century fashion and to clarify that Oriental dress and its ornaments appearing as the main subject of Occident fashion gradually The results were as follows : First, Oriental Mode in 1900-1950s was prescribed as the 'Orientalism' to be expressed Occidental imperialistic viewpoint. Therefore, the Orient was used as the simple recording mark of the imperialism product or commercial motive and it was reflected in fashion. Second, it was explained in 1960-1970s as the 'Folklore Orientalism' that focus was moved into the folklore costume of Orient. Third, in 1980s, 'Ethnic' was conspicuous that reflected the traditional costume in the area of non-christianity. Especially, it was the decade that the Middle East attracted attention. Fourth, Oriental Mode in 1990s appeared as the 'Fusion' that Oriental and Occidental elements were mixed and compromised on equal terms. Fifth, it was expressed as a word 'Zen' that had natural fiber, moderate color and silhouette to be most basic and concise about human body at the end of 1990s. This study could confirm that the center of fashion was being converted into the Orient gradually. This may be understood as the pluralistic culture phenomenon. Namely, eclectic principle to recognize mutual style and individualistic nature and to utilize and mix was made, and this brought the conversion into Oriental sense of value.

In order to recognize thermal efficiency and power improvement in case that diesel cycle is turned into diesel-atkinson cycle, the fuel-air diesel-atkinson cycle considered gas exchange process is analyzed non-dimensionally and thermodynamically. As a result, in case of diesel-atkinson cycle, as expansion ratio is increased, thermal efficiency and mean effective pressure is increased and it has maximum value at Rec=1. When diesel cycle is turned into diesel-atkinson cycle by late intake valve closing timing, thermal efficiency and power is decreased because of the decline of effective compression ratio and intake airflow, but it could be compensated by increase of compression ratio or super-charged. In case compression ratio is compensated, Rec appears 1 around 100$^{\circ}$ ABDC, and it is expected that thermal efficiency is enhanced by 14.3% compared with conventional diesel cycle. In case compression ratio and intake airflow are compensated simultaneously, super-charged pressure is demanded 2.06bar at Rec=1 and it is more efficient when only compression ratio is compensated in the view point of thermal efficiency.

This paper presents a sensing system for smart home which can detect an location transition events such as entrance/exit of a member and identify the user in a group at the same time. The proposed system is compose of two sub-systems; a wireless sensor network system and a database server system. The wireless sensing system is designed as a star network where each of sensing modules with ultrasonic sensors and a Bluetooth RF module connect to a central receiver called Bluetooth access point. We propose a method to discriminate a user by measuring the height of the user. The differences in the height of users is a key feature for discrimination. At the same time, the each sensing module can recognize whether the user goes into or out a room by using two ultrasonic sensors. The server subsystem is a sort of data logging system which read the detected event from the access point and then write it into a database system. The database system could provide the location transition information to wide range of context-aware applications for smart home easily and conveniently. We evaluate the developed method with experiments for three subjects in a family with the installation of the developed system into a real house.
