We live now in information society. High-tech communication technique of information came up to our daily life thoroughly. Then, what will happen to change the field of architecture in information society\ulcorner This study realized architecture in virtual reality by choosing technique in virtual reality that was able to alternate architecture in reality. The result of this study: 1. We promoted some shopping malls by making use of 'an active world' that is one of the virtual reality programs. As a result, we could know that we were able to find out goods faster than reality economically and purchase them in virtual reality. 2. There are many fields that we can adapt the architecture in virtual reality beside the shopping malls. For example, they can be a museum, an art gallery, and educational facility, a movie theater, a government and public office, and a recreation facility. 3. The architecture in virtual reality will cause to change our lifestyles and environments and to coexist architecture in reality.

The photonic quantum ring (PQR) laser is a three dimensional whispering gallery (WG) mode laser and has anomalous quantum wire properties, such as microampere to nanoampere range threshold currents and ${\sqrt{T}}$-dependent thermal red shifts. We observed uniform bottom emissions from a 1-kb smart pixel chip of a $32{\times}32$ InGaAs PQR laser array flip-chip bonded to a 0.35 ${\mu}m$ CMOS-based PQR laser driver. The PQR-CMOS smart pixel array, now operating at 30 MHz, will be improved to the GHz frequency range through device and circuit optimization.

Clay-dispersed nanocomposites have been prepared by simple melt-mixing of three components, i.e. poly (styrene co-acrylonitrile) copolymer (SAN), poly ($\xi$-caprolactone ) (PCL), and an organophilic clay(Cloisite(R) 30A). In the present study, poly($\xi$-caprolactone) was added in the mixtures in order to facilitate the intercalation of SAN into the gallery of silicate layers, and the molecular weight effects of PCL on the dispersion of silicate layers were compared by changing the amount of added PCL. The degree of dispersion of 10-$\AA$-thick silicate layers of clay in the nanocomposites was investigated by using an X-ray diffractometer and a transmission electron microscope. It was found that PCL added in the mixture facilitate the intercalation of SAN copolymers into the galleries of silicate layers modified with an organic intercalant, resulting in the better dispersion of clay. It was, also, observed that the processing temperature influences the degree of clay dispersion.

The form and function of modern museum present more a variety of aspects in need of transition of the mature civil society and culture than the past. Considering that an art museum is the space where a multitude of unspecified visitors inspect simultaneously, exhibitions and adequate construction make visitors lead to successively visual contact. Consequently a goal of this study is to analyze that there is correlation between exhibit space and exhibitions and to suggest an alternative plan at exhibition through relationship among exhibitions, exhibit space and spectators' behavior. Two Art galleries (one is a large-sized gallery and the other is a small-sized one) located in Pyung-Chang dong were selected to analyze the correlation and suggest the better display for the exhibition. The finding of the study is following. The exhibit space which spectators recognize is assumed diverse forms by an unique characteristics of exhibits and space and an arrangement of exhibitions and the path of flow of spectator who walking ahead have an huge effect on a spectators' behavior. In other words, spectators' watching patterns are affected by display of exhibitions and the path of flow. That is to say, the spectators' behavior and the concentration to watch exhibitions is decided by the exhibit form in the museum, and the quality of watching experience is depended on the spectators' relevant knowledge prior to exhibitions.

Photonic band gap structures have a high potential for nearly zero-threshold lasers. This paper describes new-types of low-threshold photonic crystal lasers fabricated in InGaAsP slab waveguides free-standing in air. Two-types of photonic crystal lasers are studied. One is a single-cell nano-cavity laser formed in a square array of air holes. This photonic band gap laser operates in the smallest possible whispering gallery mode with a theoretical Q >30000 and exhibits low threshold pump power of 0.8 mW at room temperature. The nther laser does not have any cavity structure and the lasing operation originates from the enhanced optical density of states near photonic band edges. A very low threshold of 35 $\mu$W (incident pump power) is achieved from this laser at 80 K, one of the lowest values ever reported. This low threshold is benefited from low optical losses as well as enhanced material gain at low temperature.

Interaction between sedentary and nomadic cultural traditions has played an important role in the centuries-old history of applied arts in Uzbekistan. By the late 19th and early 20th century, driven by urbanization in the region and the gradual transition of nomadic and semi-nomadic peoples to sedentary lifestyles, many industries and traditional cultural forms of formerly nomadic ethnic groups disappeared. Nevertheless, their role in shaping the national cultural identity of the Uzbek people is great. This is true in relation to one of the largest ethnic groups in Uzbekistan, the Kungrats, whose applied art represents a unique, viable, and yet little-studied phenomenon in the national culture of Uzbekistan. The article reviews carpet weaving, one of their surviving crafts, exemplified by qiz-gilam, a unique type of rug made using a combined technique. This study helps to show the nature of historical and cultural interrelations in the carpet weaving of Central Asian peoples and their cultural contacts with the carpet art of neighboring regions more widely and objectively. An important theoretical result of this study is the creation of criteria and tools for identifying qiz-gilam carpets. This allows us to bring clarity to the yet undeveloped system of their identification in museum and gallery practice.

An aspect of organophilic modification for the delamination is described for the layered rare-earth hydroxides in this paper. The interlayer property of $RE_2(OH)_5NO_3{\cdot}nH_2O$, where RE=Eu (LEuH) and Tb (LTbH), was modified by the exchange reaction of nitrate ion with oleate anion that is one of the representative dispersion agents in nonpolar solvents. The bilayer arrangement of long oleate anions in the gallery of $RE_2(OH)_5NO_3{\cdot}nH_2O$ could effectively weaken the stacking of the hydroxide layers. Highly organophilic environment of the interlayer space promoted the introduction of toluene to delaminate the layered structure into their individual sheets. When irradiated with 365 nm UV, the resulting transparent colloidal solutions of toluene containing LEuH and LTbH nanosheets yielded typical red and green emissions, respectively, which are visible to the naked eye.
