Wood dust is created when machines are used to cut or shape wood materials. Industries of high risk of wood dust exposure are sawmills, dimension mills, furniture industries, and carpenters, etc. Health effects associated with wood dust exposure includes dermatitis, allergic respiratory effects and cancer. Health effects of wood dus t are mainly depend on the concentration, dust size and exposure time. This study were carried out to evaluate the concentration and particle size distribution of wood dust during working processes. The subjects of this study were 53 workers exposed to wood dust in 7 furniture factories and 5 musical instruments, and 5 sawmill factories. The average total wood dust concentrations measured by personal cascade impactor were $1.82{\pm}2.31mg/m^3$ in primary manufacture, $3.59{\pm}1.72mg/m^3$ in s econdary manufacture, $5.09{\pm}1.46mg/m^3$ in sanding operation. Mass median diameters of hardwoods dust were $3.36{\mu}m$ in primary manufacture, $4.25{\mu}m$ in secondary manufacture, $4.21{\mu}m$ in sanding operation. softwoods dust were $3.39{\mu}m$ in primary manufacture, $4.34{\mu}m$ in secondary manufacture. Particle size distributions showed a nearly the same pattern in each working processes. The sample concentration of all hardwood dust exceeded the Threshold Limit Value(TLV) and 20.8% of the softwood dust exceeded the Threshold Limit Value. The range of size distribution were $0.5-10{\mu}m$ in the soft and hardwood dust. The respirable dust of soft and hardwood took up 59% and above. Therefore new threshold limit value for wood dust should be needed in Korea. Also, it should be done for various studies on health effects related to occupational exposure of wood dust.

In this study, we develop a novel high-throughput micronanopatterning system that can implement continuous mechanical pattern inscribing on flexible substrates using a rigid grating mold edge. We perform a conceptual design of the process principle, specific modeling, and buildup of a real system prototype. This research also carefully addresses several important issues related to processing and controlling, including precision motion, alignment, heating, and sensing to enable a successful micronanopatterning in a continuous and high-speed fashion. Various micronanopatterns with the desired profiles can be created by tuning the mold shape, temperature, force, and substrate material toward many potential applications involving electronics, photonics, displays, light sources, and sensors, which typically require a large-area and flexible configurations.

The purpose of this study is to investigate decoration techniques applied to the Korean traditional costume of modern style which are shown in special monthly magazines relevant to the traditional magazine. Findings of the study can be summarized as follows. The types of decoration techniques applied to the Korean traditional costume are largely classified into single and composite types. In the traditional costume of the former type, a quite many of gold and silver foils and embroideries are found. While, in that of the latter type, a combination of two different decorations, embroideries and seonchigi or multi-colored stripes and seonchigi is often used. These decoration techniques are usually applied to some parts of the costume like git, kkeutdong or cuffs, somae or sleeves, seop, goreum or coat strings, jacket or jeogori, the lower hem of the skirt and between joined parts in the skirt. Used together with the techniques, patterns are usually applied onto embroideries and gold or silver foils. Most of the patterns are flower in shape. The main material of the Korean traditional costume is fabrics that have no pattern on the surface and are commercially available irrespective of season. Git used for jeogori is largely classified into dangko git and donggrae git in type. Its color is in most cases same as the main color of jeogori. Keutdong for jeogori is usually 4 to 5.5 cm in breadth, classified as type II. Its color is in most cases white. Goreum for jeogori is usually large in length. Its color is most cases same as that of jegori or reddish purple or blackish red purple.

The Wenbing tiaobian(온병조변) is the first systematic disease monograph on warm factor disease(온병), written by Wu Jutong(오국통). It was most influenced by the Linzheng zhinan yian(임증지남의안), which was a book of gathering medical case records of Ye tianshi(엽천사). Therefore, there are plenty of quotations from this book in the Wenbing tiaobian. This study investigates the quotations from Linzheng zhinan yian, especially focusing on the way of transformation and correction of the original medical case records on the warm factor disease. The results are as follows: About 104 of 265 provisions in the Wenbing tiaobian were directly quoted from the Linzheng zhinan yian. The provisions quoted from Ye's case records were rearranged according to the categories of the triple burners pattern differentiation(삼초변증) and the causes of warm factor disease. And eve case record was transformed into more general descriptive form in order to put it into the book. For example, the specific figures, and some patients' peculiar symptoms, causes, sex and disease names were omitted. On the other hand, the tongue moss, pulse shape and some symptoms, which were necessary for differentiating patterns, were added. In the case of the formula, some formulas originated from Ye's case records were named newly. And the dose of each herb consisting a formula was determined, and therapeutic principle, taking method and detailed explanation was added to every formula.

In this paper, an augmented video generation method to evaluate the performance of lane departure warning system is proposed. In our system, the input is a video which have road scene with general clean lane, and the content of output video is the same but the lane is synthesized with contamination image. In order to synthesize the contamination lane image, two approaches were used. One is example-based image synthesis, and the other is background-based image synthesis. Example-based image synthesis is generated in the assumption of the situation that contamination is applied to the lane, and background-based image synthesis is for the situation that the lane is erased due to aging. In this paper, a new contamination pattern generation method using Gaussian function is also proposed in order to produce contamination with various shape and size. The contamination lane video can be generated by shifting synthesized image as lane movement amount obtained empirically. Our experiment showed that the similarity between the generated contamination lane image and real lane image is over 90 %. Futhermore, we can verify the reliability of the video generated from the proposed method through the analysis of the change of lane recognition rate. In other words, the recognition rate based on the video generated from the proposed method is very similar to that of the real contamination lane video.

The purpose of this study is to design an official costume of Joseon Ginyeo in the scholar’s banquet in 16th century, thereby making correct historical animation, drama costumes, and various costume contents. Every Ginyeo in and wore a long yellow coat with short front edge. 'Dan-ei', Ginyeo’s court costume, had very similar shape except color and collar, therefore the size of Dan-ei was adapted to design a yellow coat for drama actress. Ginyeo’s Jogori in these paintings was wide and long enough to cover undervelly under the edge of yellow coat, but It was designed more slim and long for better appearence and comfortable movement in my work. A skirt of Ginyeo was designed with circumference of about 360cm and length of about 105cm according as a skirt style of Joseon ladies in 16th century. Ginyeo's Jam(hairpin) was consist of a vase, a plum blossom, and a lotus pattern. And, a wide underpants with a single suspender, portable pouch, Un-hae(women’s shoes) with low heel are needed for drama actress in the role of Ginyeo. In this design, it is very important to save an estimate and time, select suitable mordern fabrics, reform discomportable points, express a charater’s role, and make a trendy appearence.
