This experiment was conducted to clarify the effects of 1-methylcyclopropene (1-MCP) on vase life of cut 'Blue Magic' iris. Pretreatment for 4 h with concentrations of 500 nL and 1000 nL 1-MCP, an inhibitor of ethylene action, inhibited the wilting and inrolling response of cut iris. The vase life of iris flowers of 500 nL or 1000 nL 1-MCP treatment was prolonged to 0.5 day compared to those held in distilled water (control). Vase life of iris showed no significant difference between $3{\mu}L{\cdot}L^{-1}$ ethylene exposure after 1-MCP treatment and control. 1-MCP treatment inhibited inrolling and increased fresh weight, water uptake, and water balance. The increase of fresh weight was high in 500 nL 1-MCP treatment and water uptake was increased by 1000 nL 1-MCP. Especially, iris flower without 1-MCP treatment dramatically decreased the water uptake as compared to the control for four or five days. Water balance of iris flowers held in water was changed to minus value faster than those with pretreatment of 1-MCP.

Ion-molecule reactions of acetylene and mixed acetylene-ammonia cluster ions are studied using an electron impact time-of-flight mass spectrometer. The present results clearly demonstrate that $(C_2H_2)_n^+$ cluster ion distribution represents a distinct magic number of n=3. The mass spectroscopic evidence for the enhanced structural stabilities of $[C_6H_4{\cdot}(NH_3)_m]^+$ (m=0-8) ions is also found along with the detection of mixed cluster $[(C_2H_2)_n{\cdot}(NH_3)_m]^+$ ions, which gives insight into the feasible structure of solvated ions. This is rationalized on the basis of the structural stability for acetylene clusters and the dissociation dynamics of the complex ion under the presence of solvent molecules.

A communication-aid circuit to detect eye-gazed patterns is proposed in this paper. The circuit is an analog-digital mixed system. By determining the direction of eye-gazed pattern, the circuit detects an eye-gazed pattern from 2-dimensional arrayed patterns on a syllabary. Different from conventional systems, the syllabary is moved to overlap the eye-gazed pattern with the center coordinate of screen. Thus, the proposed circuit can avoid a complex calculation of the distance between the eye-gazed point and the center coordinate. Furthermore: an economical size of hardware can be provided since no full-adders are required by employing floating-gate MOSFBT's. The validity of the cricuit design is confirmed by computer simulations. Furthermore, to implement onto an IC chip, the layout design is performed by using a CAD tool, MAGIC.

This treatise begins with finding a meaning of Paul Klee's . It is pretty simpleto choose the square of Klee. The most important formative language for twenty century is abstraction. The element of speaking for abstraction issquare. The artists are trying to contain the nature and universe in the square. The role of magic square consisting with small squares of Klee is crystallized. The other side, the test of this study is a method analysis. The method analysis is changing while concept and style have been changing according to a period. The existing method analysis is an iconology used many times in Art history. This treatise introduces France symbolists, Bernard Cocula and Claude Peyroutet's analysis of a meaning of image(Semantique do l'image) who were applied to Modern Art. based on Iconography. It also applies to analysis of artwork of Klee. Cocula's is developed from one phase to five phase step by step. The first phase deals with an appearance of artwork. Subsequently, the second phase is directly adjacent to personal feeling and impression. This is an adequate method for image study in the analysis of modern arts. This phase makes it a rule to enjoy talking with artworks above all. The third phase begins with this question 'What do you see? (que voyons-nous?).' The applies exhaustively and strictly to complicated image artworks which need an elaborate analysis. It is very hard but audiences must try to maintain neutrality in front of artwork because cord formation and interpretation should be formed objectively. The meaning analysis and interpretation of the forth phase begins with this question 'what is the image rouse'(qu'evoque cote image?).' This phase is the most important in a process of symbolic analysis. The audience investigates personal elements and common elements. The fifth is synthetic analysis and interpretation phase. The synthesis is last phase and it reaches a valuation and a conclusion. Namely, the synthesis phase makes up synthesis conclusion, summarizes image character, and completes value adjudication. Sometimes it completes no conclusions in a silence. This study found a new possible analysis example from Paul Klee's work. The study emphasizes square analysis and interpretation and uses . The analysis of artwork by Cocula's is an example of the most important work of Klee's three artworks. The first analysis of artwork is and the second one is . The third one is . In these analyses, Klee usedmagic square 'to make natural pictorial element and to explain organic living things.'

Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50％ shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22％ was found in the rain shelter as compared to the that of 19∼83％ in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.

This research was aimed to extend the vase life, improve the cut flower quality and promote flowering rate of bulbous cut Iris 'Blue Magic'. Three different concentrations of 1-MCP ranging from 250 to $750nL{\cdot}L^{-1}$ were treated on cut Iris flowers for the vase life elongation. Several effects of 1-MCP treatment has shown such as early flowering as one day but vase life showed no significant differences comparing to the untreated control. Flowering rate was 75% or more in the treated ones as compare to 64.2% in untreated control. Especially, in a treatment with $250nL{\cdot}L^{-1}$ 1-MCP for 12 hours it showed all flowering. In many post-harvest experiments of cut flowers, ethylene production from flower organ has considered as most critical factor on vase life. Ethylene production from flower organ was measured by gas chromatography (GC) and it showed that there is no direct relation between flower longevity and emission of the ethylene gas in cut Iris. In comparison with the untreated control, ethylene generation rather seems to be increased as 1-MCP treatment increased. There was a synergy effect when 1-MCP and BA applied simultaneously in which flowering and vase life were fastened and also extended, respectively. Therefore, treatment of 1-MCP for cut Iris at flower early harvest is able to improve the flower quality both by diminishing non-flowering rate and by extended flower longevity.

Image making for a person is a way to improve various factors that can express oneself, such as appearance, impression, and confidence. In general, people use mirror or camera as a traditional method to make their own image or perform presentation exercises. Recently, as smart mirrors are widely used in various fields, attempts to use smart mirrors as image making tools instead of mirrors have been frequently made. Smart Mirror is considered as a suitable tool to provide image making service because it can attach various devices such as a camera and a microphone in addition to the main advantage of a mirror that it is easily accessible. In this paper, we present BuddyMirror - a smart mirror software that provides image-making service to users, and a dedicated mobile app for flexibly running the mirror software. BuddyMirror provides functions for presentation, mock interview, and styling service at the request of users, interworking with the dedicated mobile app. We also describe the techniques developed for implementing and activating each of the new services as a module of MagicMirror, a widely used smart mirror development platform. The developed mobile app enables users to deliver presentations to BuddyMirror or to download the recorded video for image-making services.

To minimize the variance in the quantification of solid-state phases in powder samples, gently placing polycrystalline samples one next to another directly in a sample holder is better than trying to mix them homogeneously prior to transferring to a sample holder. However, the solid-state cross polarization-magic angle spinning (CP-MAS) nuclear magnetic resonance (NMR) spectroscopy results demonstrated that it is essential in this sampling method to place all the samples in the location of consistent signal sensitivity. The same sampling method may be employed in other spectroscopic quantification techniques of solid-state phases if the method to limit the sample to the location with uniform signal sensitivity in the sample holder is adapted to each technique.
