Sporulation in the fission yeast Schizosaccharomyces pombe has been regarded as an important model of cellular development and differentiation. S. pombe cells proliferate by mitosis and binary fission on growth medium. Deprivation of nutrients especially nitrogen sources, causes the cessation of mitosis and initiates sexual reproduction by matting between two sexually compatible cell types. Meiosis is then followed in a diploid cell in the absence of nitrogen source. DNA fragment complemented with the mutations of sporulation gene was isolated from the S. pombe gene library constructed in the vector, pDB 248' and designated as pDB(spo5)1. We futher analyzed six recombinant plasmids, pDB(spo5)2, pDB(spo5)3, pDB(spo5)4, pDB(spo5)5, pDB (spo5)6, pDB(spo5)7 and found each of these plasmids is able to rescue the spo5-2, spo5-3, spo5-4, spo5-5, spo5-6, spo5-7 mutations, respectively. Mapping of the integrated plasmid into the homologous site of the S. pombe chromosomes demonstrated that pDB(spo5)1, and pDB(spu5)Rl contained the spo5 gene. Transcripts of spo5 gene were analyzed by Northern hybridization. Two transcripts of 3.2 kb and 2.5kb were detected with 5kb Hind Ⅲ fragment containing a part of the spo5 gene as a probe. The small mRNA(2.5kb) appeared only when a wild-type strain was cultured in the absence of nitrogen source in which condition the large mRNA (3.2kb) was produced constitutively. Appearance of a 2.5kb spo5-mRNA depends upon the function of the meil, mei2 and mei3 genes.

The purpose of this study is to examine the characteristics or significances of anger in children by understanding the common factors observed in children's anger and the psychological process of children's anger, applying the experiential analysis method. In order to conduct the study, 8 elementary students in 5th grade participated in the experiential study as joint researchers. This study was conducted during 6 sessions. Joint researchers learned about the experiential analysis method and recorded what they had experienced at the stage of anger on their analysis sheets. 34 experiential analysis sheets were used for this study. The following provides a summary of the study results. Children were observed to perceive the factors representing desires more intensely than the factors indicating a mood or senses. Secondly, when they felt urge to express an extreme anger, they were just explored without the cognitive process of judgment. Thirdly, the processes that children feel and treat anger are "the stage of awareness of the situation," "the stage of initial cognitive evaluation," "the stage of induction of anger," "the stage of secondary cognitive evaluation or the stage of intensive drive of anger," and "the stage of anger management".

Typography in visual communication design is 'potential form' hidden within a space. Showing rhythm in typography is making 'aesthetic sense' in a graphic which has formative characteristics, the way of expression is very important. When the rhythm is recognized through visual stream, Rhythmic Sense is formed. The research will present a new form of the Visual Rhythmic Sense by analyzing typography works out positively. First of all, I researched works done by Fillippo Marinetti, Robert Massin, Wolfgang Weingart, and David Carson for their vigorous experimentalism in typography in forming visual rhythm. I used S.D. Scale method to analyze characteristics of visual image and VARIMAX for factor analysis reaching types of visual rhythm, which could be classified as following. (1) Synesthesia Rhythmic Sense (R-synesthesia) means that the senses are conveyed through 'visualization of auditory sense' and 'visualization of touch' (2) Simultaneous Rhythmic Sense (R-simultaneity) means that the time and space co-exist in one plane. (3) Connective Rhythmic Sense(R-connection) means that different factors (Within one plane) co-exist interacting with one another and creating a unified impression through such a process. (4) Artist Oriented Rhythmic Sense ($-artist) means that the artist interprets the content subjectively and expresses his/her impression, thereby, attracting a gaze of audience systematically and arbitrarily. (5) Reader Oriented Rhythmic Sense(R-reader) avoids the existing legibility formed through aggressive engagement of the reader.

The purpose of this study is to clarify how modern formative art reflects surrealism and propose a Art Make-up expressed based on the trend. The study also aims at demonstrating the part that the Make-up based on surrealism is also an artistic being keeping pace with the trend of art. For the purpose, the study reviewed related theoretical backgrounds and works as manufactured. Based on these theoretical backgrounds, the author anufactured works of his own, realizing the combination between theoretical and practical aspects. Those works were motivated from existing surrealistic paintings or otherwise made surrealistically through creation by the author for himself. The works included , (Work 2-MAGRITTE's Expression>, , , and . Results of the study, which were obtained through manufacturing the works, can be described as follows. First, senses of modern formation and line were emerged by applying the materials and images frequently shown in surrealistic paintings to human bodies. Second, characteristics of the Art Make-up for artistic image were revealed, not limited to colors, expressions, subjects, techniques and materials. Third, an unlimited, interesting expression of the Make-up using a variety of materials became possible by applying extremely subjective, surrealistic paintings and images in various ways. This paper proposed that the Make-up should be a artistic image itself, not as a secondary means for an obvious expression of personal beauty which has been maintained since the ancient times. The researcher tried to put the Art Make-up into our daily life by making creative works which viewed and psychologically enjoyed by people and by proposing the works as sort of image theme to the spectators.

In this paper, we propose the NAVER, a general framework for multipurpose virtual environments, and introduce the case study of evaluating car prototypes using cave-like systems. As a framework to implement variant applications in virtual environment, NAVER is extensible, reconfigurable and scalable. NAVER consists of several external modules (Render Server, Control Server and Device Server), which communicate each other to share states and user-provided data and to perform their own functions. NAVER supports its own scripting language based on XML which allows a user to define variant interactions between objects in virtual environments as well as describe the scenario of an application. We used NAVER to implement the system for evaluating car prototyes in a CAVE-like virtual environment system. The CAVE-like virtual environment system at KIST consists three side screens and a floor screen (each of them is a square with side of 2.2m), four CRT projectors displays stereoscopic images to the screens, a haptic armmaster, and a 5.1 channel sound system. The system can provide a sense of reality by displaying auditory and tactile senses as well as visual images at the same time. We evaluate car prototypes in a CAVE-like system in which a user can observe, touch and manipulate the virtual installation of car interior.

It was common that the classification of itching was classified into four categories according to the neurophysiological mechanisms of pruritoceptive itching, neuropathic itching, neurogenic itching and psychogenic itching. Recently it was classified by clinical criteria. The neurotransmission pathway of itch is divided into histamine-dependent pathway and histamine-independent pathway. Different receptors and neuropeptides act on each itch mediator. Itch mediators such as histamine, BAM8-22, and chloroquine are transmitted through the histamine-dependent pathway. Cowhage spicule, protease, and TSLP (Thymic stromal lymphopoietin) have been reported to be related to the histamine-independent pathway. These itch mediators, receptors, and neuropeptides are the targets of treatment for itching. Although itching and pain are typical noxious stimuli, and in the past, it was argued that two senses were transmitted through one noxious stimulus receptor. It has recently been shown that itching and pain have an independent neurotransmitter system and both neuronal systems inhibit each other. In addition, the mutual antagonism between itching and pain is explained by various mechanisms. Recently, many new mediators and receptors are being studied. The studies on histamine 4 receptor (H4 receptor) have been actively conducted. And the H4 receptors are expressed in immune cells such as T cells. The therapeutic agent for blocking the H4 receptor can inhibit the inflammatory reaction itself, which is important for the itching and chronicization. Understanding the underlying mechanisms of itching and studying new itch mediators will lead to the development of effective therapies, and this is what I think the itching study will go on.

As a basic study on both engineering applications and representation methods of synesthesia, this paper aims at building basic system which converts a muscular sense into both visual and auditory elements. As for the building method, data of the muscular sense can be acquired through roll and pitch signals which are calculated from both three-axis acceleration sensor and the two-axis gyro sensor. The roll and pitch signals are then converted into both visual and auditory information as outputs. The roll signals are converted into both intensity elements of the HSI color model and octaves as one of auditory elements. In addition, the pitch signals are converted into both hue elements of the HSI color model and scales as another one of auditory elements. Each of the extracted elements of the HSI color model is converted into each of the three elements of the RGB color model respectively, so that the real-time output color signals can be obtained. Octaves and scales are also converted and synthesized into MIDI signals, so that the real-time sound signals can be obtained as anther one of output signals. In experiments, the results revealed that normal color and sound output signals were successfully obtained from roll and pitch values that represent muscular senses or physical movements, depending on the conversion relationship based on the similarity between color and sound.

This study investigated many factors which had to be considered importantly in space planning for the cultural contents exhibition hall on the basis of establishment cases at this time that cultural contents were considered very importantly in the national economy. It must be a priority to set up the concept of the exhibition space which can encompass exhibition spaces, exhibits, the approach to experience exhibitions and others for the effective planning for exhibition spaces showing cultural contents. Visitors' moving lines should be planned based on that concept setting. It is necessary to reflect human attributes that people detect environmental information and perceive the environment through their sensory organs and plan moving lines considering visitors' cognitive, emotional and psychological factors which they can feel according to the temporal order. In addition, this study led visitors to respond exhibits through their five senses and increased the effects that visitors appreciated exhibition spaces, actively getting out of the way that visitors experienced exhibitions, which might be limited to sight. This study will be able to provide specific space planning methods related to the establishment of cultural industry-based professional exhibition halls which have been increased day by day at this time that culture-based industries are considered to be important. Moreover, it will be helpful in reducing the trial and effort factor in the exhibition hall establishment project.

This study is to analyze the contents related to 'state of water', 'state change of water', and 'conditions of state change' in K-12 science textbooks. For this, we analyzed textbooks based on the 5th kindergarten curriculum, the 6th elementary school science curriculum and the 6th middle school science curriculum. Findings show that some of the contents are designed well by topical sequencing or by spiral sequencing. But others have some problems based on topical sequencing and spiral sequencing. Generally, the contents are represented in the order of Perception of phenomena with senses level, Macroscopic understanding level, Understanding of scientific term level, Microscopic understanding level by grade. But the state change contents related to solidification and melting, and conditions of state change contents related to heat, temperature, wind, and humidity are not represented in the level of Microscopic understanding. The contents of state change and conditions related to heat and wind are not represented in the level of scientific term also.

This study suggests a new platform in which VI can communicate with their guardians who serve as a system administrator optimizing personal characteristics. In terms of interaction between platform components, this study can contribute to enhancing stability of walking by giving substantial information to VI through server processing and setups of guardians with real-time interaction to VI through server processing and setups of guardians with real-time interaction. Therefore, developing smart phone applications can facilitate both portability and cost effectiveness, by the users' downloading the application and registration. In terms of guardians' cost, this system is cost-effective because they can access to the administration system through personal computers or smart phones, not through specialized system devices. This system is web-based, which automatically communicates with the surroundings of, such as provides the guardians with the necessary information or approaches to the danger through IoT devices, which results in enhancing safety. Moreover, it is possible for guardians to utilize the personalized platform since the system not only senses personal characteristics but also sends a number of information to VI. a new platform makes it possible for guardians to provide electronic support and interaction with the application with the application users, which contributes to systematic and safe walk for VI.
