  • Generative Art (also called as the art of the algorithm) creates unexpected results, moving autonomously according to rules or algorithms. The evolution of digital media in art, which tries to seek novelty, increases the possibility of new artistic fields; subsequently, this study establishes the basis for new design approaches by analyzing visual cases of Generative Art that have emerged since the 20th century and characteristics expressed on fashion. For the methodology, the study analyzes fashion designs that have emerged since 2000, based on theoretical research that includes literature and research papers relating to Generative Art. According to the study, expression characteristics shown in fashion, based on visual properties of Generative Art, are as follows. First, abstract randomness is expressed with unexpected coincidental forms using movements of a creator and properties of materials as variables in accordance to rules or algorithms. Second, endlessly repeated pattern imitation expresses an emergent shape by endless repetition created by a modular system using rules or 3D printing using a computer algorithm. Third, the systematic variability expresses constantly changing images with a combination of system and digital media by a wearing method. It is expected that design by algorithm becomes a significant method in producing other creative ideas and expressions in modern fashion.

  • The fundamental dispersion property of Si2N4 and a combination of AlN and Nd2O3 as sintering additives in a variety of organic solvents such as alcohols, hydrocarbons, ketones, and ethers was investigated. The stabilization mechanism and interaction between organic functional groups of the various organic additives were studied to clarify the dispersibility of the ceramic particles in the nonaqueous suspending medium. characterization of the suspensions was based mainly on electrokinetic sonic amplitude(ESA) measurements and the flow curves obtained from the rheological studies as well as estimated Hamaker constants. It was found that the contribution of electrostatic repulsive forces to the Si3N4, AlN and Nd2O3 stabilization in organic media is appreciably greater than anticipated and is dependent on the physicochemical properties of organic solvents.

  • Due to the advancement of technology, there are many attempts trying to extend ways of expressing for using digital media, even in traditional theater. In the performances that were created before '미키쥐의 죽음' directors used videos only for the background, however, in 'A Death of Mickey Rat', trying to avoid the same patterns as the ones from the past creators realized an interactive performance with the balancing combination of videos, performer and sounds. As a result, the theater suggested a possibility of a new progress in creating theater by making a created space called the stage gain more reality and adding the power of interactivity between the media and the performer.

  • To establish in vitro nodal culture conditions of Echinosophora koreensis Nakai, one of rare and endangered species famous for beautiful flowers in the Korean Peninsula, the influence of plant growth regulators (PGRs) on shooting and rooting from in vitro shoots was investigated. In shoot multiplication, addition of 6-benzylaminopurine (BA) to the half-strength Driver and Kuniyuki's media in the range of 2.22 to 8.88 ${\mu}M $induced 2.5 to 2.7 shoots per axillary bud; and addition of 2.27 ${\mu}M $ thidiazuron (TDZ) produced 3.2 shoots, during 4 weeks of culture, while zeatin and isopentenyl adenine (2ip) were not effective on shoot multiplication as observed from several combination treatments of BA with other PGRs. Shoots established were smaller than 2 cm in length, in most of the treatments. while in BA 8.88 ${\mu}M $ treatment more than 30% of shoots were longer than 2 cm and shorter than 4 cm. In rooting, naphthalene acetic acid (NAA) from 5.37 to 21.48 ${\mu}M $ showed the rooting rate from 40.0 to 62.5%. Indole butyric acid (IBA) addition had little effect on rooting (<10%), although some roots in IBA-containing media were longer than those in NAA. Micropropagation from axillary buds of nodular explants was applicable and promising to multiplication and conservation of Echinosophora koreensis Nakai.

  • Wild type Bacilus thuringiensis subsp. israelensis and B. sphaericus toxins have been used separately as active in ingredients for bacterial insecticides to control mosquito larvae due to their comparable toxicity to chemical insecticides. Cry11B, recently cloned from B. thuringiensis subsp. jegathesan, shows higher toxicity against three major species of mosquito larvae than Cry11A, one of the major component of B. thuringiensis subsp. israelensis inclusion body. To determine whether the combination of cry11B and B. sphaericus binary toxins is as toxic as B. thuringiensis subsp. israelensis parental strain, cry11B and B. sphaericus binary toxins genes were co-expressed as an operon using cytlA promoters/STAB-SD hybrid expression system in B. thuringiensis subsp. israelensis acrystalliferous strain 4Q7. However, unexpectedly, B. sphaericus binary toxins were barely produced, whereas relatively large amount of Cry11B was produced. When this strain was grown in four different media, NB+G and Peptonized Milk produced more toxin proteins and spores per unit of media than GYS and G-Tris. Toxicity of this strain against fourth instar Culex quinquefasciatus was ranged from of 8.3 to 45.7 ng/ml, with NB+G culture being the highest, and GYS culture was the lowest.

  • Germination efficiency, such as days to germination and conditions for the hybrid seeds, was tested after hybrid seeds were sown on the medium. Seeds were germinated from 67 to 126 days after seeding in all cross combinations, and germination condition was different among hybrid combinations. There was big difference on days to germination based on the different media, that is, days to germination in the hyponex medium was shorter than that in the Knudson C medium. Mutants such as MMS and NaN$_3$ were used to cause mutation. Germination occurred with 0.1 % NaN$_3$ and MMS. However, even though germination occurred in other treatments (0.01 % and 0.2% of NaN$_3$ and MMS), brownish phenomenon was intense, or did not proceed and got worse after 4-5 months of seeding. In addition, it was performed to choose appropriate medium for the growth of Cymbidium rhizome whose media adaptability is more different than other orchids. Different concentration of NAA and Kinetin was used. As a result, C. goeringii hybrid showed difference for the concentration of NAA and Kinetin combination.

  • A Micrococcus sp. producing catalase was isolated from soil, and a commercial-scathe cultivation and purification of catalase were conducted. The maximum catalase activity was about 103 BU/mL obtained after 46 hr of cultivation in a 30 L fermenter containing 2% glucose, 2% peptone, 4% yeast extract, and 0.5% NaCl. Soybean sauce, CSL (corn steep liquor), and yeast extract were also studied as media substitutes in the media 30 L fermenter. The optimum medium components for the production catalase were found to be 2% glucose, 4% soybean sauce, and 16% CSL. In a 18 kL fermenter, the stationary phase in the cell growth and maximum catalase activity (112 BU/mL) were reached after 46 hr of cultivation, which was the same result as in the 30 L fermenter. The catalase activity was purified with over 17 folds in four steps with a 33.6% yield. From 104,250 mg of protein after cell lysis, 1,966 mg of the purified enzyme with a specific activity of 192.7 kBU/mg was obtained. The residual activity with the addition of 10% NaCl exhibited more than 100%. The use of just NaCl produced a higher residual activity than combination of bencol (benzyldimethyl ammoniumchloride) and PG (propyleneglycol).

  • This test method covers a procedure for measuring particle removal characteristic of equipment fan filter unit(EFFU) installed inside of semiconductor process equipments, FPD manufacturing equipments and so on. Since EFFU is a combination of air filter and the assembly of fan, motor and frame, the integrity of these parts is very important for the performance of EFFU. So a conventional particle removal test method for air filters is not suitable for EFFU particle removal performance. This test method defines an evaluation method for EFFU which is installed inside an enclosed space to remove particles that are generated inside process equipment. The particle removal performance of EFFUs is usually depending on the performance of filter media and air flow rate. To understand a performance of an EFFU, the filter media characteristic, air flow rate and the integrity of EFFU parts should be considered simultaneously. This test method is intended to demonstrate the system performance of an EFFU and successfully evaluated EFFU performance characteristics.

  • In this paper, we proposed a new object tracking algorithm based on sparse representation to handle the drifting problem. In APG-L1(accelerated proximal gradient) tracking, the sparse representation is applied to model the appearance of object using linear combination of target templates and trivial templates with proper coefficients. Also, the particle filter based on affine transformation matrix is applied to find the location of object and APG method is used to minimize the l1-norm of sparse representation. In this paper, we make use of the trivial template coefficients actively to block the drifting problem. We experiment the various videos with diverse challenges and the result shows better performance than others.
