  • To date the engineering community has seen facade systems as non-structural elements with high aesthetic value and a barrier between the outdoor and indoor environments. The role of facades in energy use in a building has also been recognized and the industry is also witnessing the emergence of many energy efficient facade systems. This paper will focus on using exterior skin of the double skin facade system as a dissipative movable element during earthquake excitation. The main aim of this study is to investigate the potential of the facade system to act as a damper system to reduce earthquake-induced vibration of the primary structure. Unlike traditional mass dampers, which are usually placed at the top level of structures, the movable/smart double skin facade systems are distributed throughout the entire height of building structures. The outer skin is moveable and can act as a multi tuned mass dampers (MTMDs) that move and dissipate energy during strong earthquake motions. In this paper, using a three dimensional 10-storey building structure as the example, it is shown that with optimal choice of materials for stiffness and damping of brackets connecting the two skins, a substantial portion of earthquake induced vibration energy can be dissipated which leads to avoiding expensive ductile seismic designs. It is shown that the engineering demand parameters (EDPs) for a low-rise building structures subjected to moderate to severe earthquakes can be substantially reduced by introduction of a smart designed double skin system.

  • The purpose of this paper is to be studied the Devil's types and the special effect makeup's techniques expressed on horror movies. As the theoretical background, the researcher inquired the origin of Satan, Demon and Devil, and the shapes and meanings portrayed in the religion, philosophy art and literature. Also classified the Devil's types of the movies, and examined the factors, techniques and aesthetic characteristics of special effect makeup for each of them. The results are as follows. 1. The Devil's types are the Werewolf, the Zombie and the Vampire. The Werewolf is a kind of Devil that changes into a wolf when the full moon rises. It requires animatronics, rubber body suits, furs and fangs for special makeup effects. The Zombie is a dead body that the exorcist restored with a narcotic drug, and it nibbles on human's brain and flesh. So it needs decayed or pale skins, scars, bald heads, non-focus eyes and false teeth for making this character. The Vampire is a bloodsucking ghost. Therefore, it uses fangs, evil eyes, rubber body suits and dropping blood for special effect makeup. 2. They expresses Sadism, Masquerade and Cruelty as the aesthetic characteristics of the Devil's special effect makeup.

  • Formerly, it was called a tent and now, it is called membrane structure. If saying a tent, it imagines the tent of Bedouin, Mongolia and North American Indian. It became clear from the excavated wall painting that have been covered with the retractable roof of the canvas on the auditorium at the amphitheater in Pompeii and became a topic. These tents were made of the animal skins or fabric woven with the flax plants, and these tents are still used. However, if saying membrane material at present, it says the one to have applied a coating resin to the textile. Because the base fabric of membrane material is a woven fabric, the relation between the stress and the strain is different to the direction of the weaving thread. Moreover, the tensile force must always occur in the membrane surface. From these reasons, because the membrane structure corresponds to the particular building material and the construction method about the Building Standard Law, it must be examined specially that the membrane structural building have the same or any more safety as the provisions which was set to the Building Standard Law. Therefore, the technical standards about the membrane structural building became indispensable. In the paper, the kinds of the membrane materials, which are used for the membrane structural buildings, and technical standards process of the creating for the membrane structure buildings are introduced. Lastly, some of the soccer stadiums for 2002 FIFA World Cup KOREA/JAPAN which be covered with the roof of the membrane structures are presented.

  • Two 1-year old calves of Korean Native cattle (Hanwoo) presented cutaneous papillomas on the face and neck. Type 2 bovine papillomavirus (BPV-2) was identified in the cutaneous papillomas based on BPV-specific PCR and subsequent DNA sequencing analysis results. Using DNA samples extracted from two affected calves and unaffected animals reared in the same stable, BPV-2 was not only detected in the cutaneous papillomas of affected animals based on BPV-specific PCR analysis, but also detected in normal skins, hairs, and their environments based on nested PCR analysis. BPV-2 was also detected in DNA samples isolated from animals and environments of that distinct stable with affected calves. However, no BPV-2 was detected in the drinking water of both stables (infected and unaffected). These findings concluded that BPV-2 was transmitted by direct or indirect contact, not by drinking water. This is the first report to show molecular evidence of BPV-2 infection. Rapid and precise molecular identification can be used to screen BPV-2 in cattle farms to understand the biological roles of BPV in animal diseases.

  • A healthy 30-yr-old woman carrying an insect that had been caught in her living room visited the International Clinic at Severance Hospital, Seoul, in December 2007. The insect she brought was identified to be a nymph of a bedbug, Cimex lectularius, and her skin rashes looked typical bedbug's bites. Her apartment was investigated, and a dead body of a bedbug, cast skins, and hatched eggs were found in her rooms and neighbors' rooms in the same building. She was living in that apartment in Seoul for 9 months since she had moved from New Jersey, USA. We assume that the bedbugs were introduced from abroad, since there had been no report on bedbugs in Seoul for more than 2 decades at least. This is a report of a reemergence of the common bedbug, C. lectularius in Seoul, Korea.

  • The present study is designed to trace the successful reform steps taken within the vocational training system in the UK and to extract a set of instructive implications for Korea's future reform path towards an efficient vocational training system conducive to youth employment. To this end, this study focuses on three major aspects of the youth vocational training system: the government's role and partnerships between training and industry, the vocational training system, and the employment support system. Implications drawn from the comparative analysis are as follows. Vocational training reform should be made within the broad paradigm of youth employment promotion. All aspects of the youth vocational training system, such as the training program structure, program content, provider, management, so on, should be reformed, step by step, within a long-term plan. In addition to the vocational training reforms. employment support programs should be enlarged, and the service delivery system should be well structured in order to enhance the effects of the training reforms. For these reforms, it is essential to make fundamental changes in the following areas: integration of youth employment policy making and its administrative structures, reinforcement of partnerships between training and industry, nation-wide standardization of job skins, and the introduction of standardized job certificate classification on a national level.
