This study was intended to develop a multi-purpose, multi-functional design for safety vest to enhance the safety and user's availability. With a limited scope to LED-applied safety vest, this study contemplates on the problems of safety vest on the market and directions for design development with a view to develop its prototype. This is a significant study because it has been conducted concerning a prototype, a cut above the study method of constructing a basic theory. For study method, theoretic considerations on LED and safety vest are followed by case study for LED-applied safety vest currently on the market to draw out problems. Then, solutions for problems with LED safety vest will be found, while planning for a design direction in consideration of safety, functionality and beauty. Scope of study was limited to cases of LED safety vests currently on sale online and offline, excluding cases of common-form luminosity such as HB luminous vest without LED. Accordingly, results of study will help develop the prototype for LED safety vest with an increase of the wearer's safety, and be used as a basic data for developing high-value-added fashion prodcts to meet his aesthetic sense and functionality. This study has limitations. Restricted scope for LED-applied safety vest should be extended to an outdoor wear in follow-up research for the foundation of higher value added.

The effects of defatted soy flour on the physicochemical characteristics of dough and bread-making properties were studied with sodium stearyl lactylate(SSL) as an emulsifier. Defatted soy flour was added to the wheat flour at the level of 0$\sim$12%. The emulsifier was added to the wheat flour-defatted soy flour blends at the level of 0.5 and 2%. Set-back and consistency in amylogram were significantly decreased as the level of soy flour was increased. On comparison with control, the bread made from defatted soy flour especially had less specific loaf volume. The specific loaf volume of wheat flour-defatted soy flour bread prepared with 0.5$\sim$2% SSL was better than that without SSL. Decrease of L value (lightness) of crust color and decrease of L value of crumb color were shown with the increase of defatted soy flour. From the result of sensory evaluation, wheat flour-defatted soy flour bread containing up to 6% defatted soy flour with 1.0% SSL were rated as high quality. Most of texture parameters of bread increased with the increase of defatted soy flour and decreased with increase of SSL. Considering the volume and sensory characteristics of bread, bread prepared with 6% defatted soy flour and 1% SSL was regarded as highly acceptable.

This paper intends to improve caddies' vocational efficiency, to increase the quality of caddies' services for customers, and further, to widen the application of smart clothes by proposing prototypes of smart uniforms in which caddies' vocational characteristics are reflected. The smart uniforms proposed by this study were restricted to those for spring and fall seasons and three types for a jacket, a turtle neck shirt, pants, and a jumper were proposed. Each design was developed to contain functionality and aesthetic, and also to be transformed subject to weather or other conditions. In addition, the uniforms were designed to carry not only a two-way radio and a remote controller for a cart that caddies necessarily carry, but also i-Pod, a distance meter, and other digital tools by use of solar cells. That is, this paper proposed the designs that can meet with caddies' vocational characteristics and different conditions. This paper is regarded meaningful in that smart clothes, which are forecasted as a future high value-added business, are applied to the uniforms of various job types so they can expand me existing functions of uniforms and further, think about the ways of being used for higher value-added products through the fusion with technologies.

We have investigated microwave dielectric properties of TiO$_{2}$ added (Pb$_{1-x}$Ca$_{x}$)ZrO$_{3}$ Ceramics with x=0.33, 0.35, and 0.37 sintered at 1400$^{\circ}C$ for 2 h. For additions of up to 3wt% of TiO$_{2}$ in (Pb$_{0.63}$ Ca$_{0.37}$)ZrO$_{3}$ (x=0.37), TiO$_{2}$ was completely soluble in (Pb, Ca)ZrO3 phase and did not affect the grain size of ceramics. Dielectric constant and temperature coefficient of resonant frequency increased due to the formation of solid solution, whereas Q value decreased linearly as TiO$_{2}$ increased up to 1 wt%. However, the dielectric loss was very high as TiO$_{2}$ exceeded 2 wt%. It was also shown that as Ca ion content in 0.5 wt% TiO$_{2}$ added (Pb$_{1-x}$,Ca$_{x}$)ZrO$_{3}$ decreased from x=0.37 to x=0.33, dielectric constant increased and Q value decreased.

Masan Port, which is a main entrance to Korea, has undergone the tough time these days. Many problems are mainly due to the deterioration of harbor facilities, the shortage of waterfront area and the decrease of the trading volumes. Especially the trading volumes are seriously affected by the Busan New Port, which was not only very close to the Masan Port but constructed in a large scale. For the Masan Port to develop continuously, therefore, it is vital to modernize harbor facilities, redevelop the old harbor, expand its waterfront, construct green port and develop harbor for sightseeing. At the same time, Masan port should be ready to develop a higher value added port. To vitalize Masan port's economy, we have to push forward a differentiation strategy that makes Masan port specialized harbor for distributing goods like hard and heavy cargo.

The principal objective of this study was to evaluate the quality of Yukwa prepared with mulberry leaf (Morus alba Linne) powder. The moisture, crude protein, crude lipid, crude ash, dietary fiber, and rutin contents of used mulberry leaf powder were 6.65%, 19.50%, 3.26%, 18.24, 38.91 and 0.54%, respectively. The tested concentrations of mulberry leaf powder were 0, 3, 5, and 7%. The Yukwa were stored at $45^{\circ}C$ for 40 days. Yukwa dough prepared with mulberry leaf powder had a lower pH compared to the control group. As more mulberry leaf powder was added, the spread ratio, moisture content, and volume increased. As more mulberry leaf powder was added, L-value decreased while a and b values increased with increasing mulberry leaf powder content. The hardness of Yukwa made with 7% mulberry leaf powder was the highest among the samples. In the sensory tests, Yukwa with 5% mulberry leaf powder received the highest scores. The acid value and peroxide values were lower in Yukwa prepared with mulberry leaf powder than control. Yukwa prepared with mulberry leaf powder strongly inhibited oxidation of lipids. The thiobarbituric values were lower in Yukwa prepared with 5% mulberry leaf powder than in Yukwa prepared with 3% and 7% mulberry leaf powders and control Yukwa. These results suggest that mulberry leaf powder can be applied to Yukwa to achieve high quality and functionality.

Ironically, marine bioresource production in Chungnam Province is the second-largest in the country. The province's marine bioresource production puts its lack of a marine bioindustry in the spotlight despite the region's favorable conditions to produce representative value-added and (ultra) high value-added products such as neutraceutical and/or pharmaceutical function. This juxtaposition is to be expected, as there are no institutions for training professionals in the field of marine biology or in the fisheries industry in the West Sea area. The unique features of the region require individuals with specialized training who have been educated in accordance with regional development and the specificity of the region. Recently, however, a plan has been initiated at the national level to foster the growth of the marine biology industry in the Chungnam Province on Korea's west coast. This plan includes increasing funds to the marine biology market to 1.2 trillion by 2030. If the Chungnam region wants to successfully revitalize the marine biology industry and put the increased funds to efficient use, it must first establish various research and (business) development (R&(B)D) plans regarding local marine biology infrastructures and marine biology programs at local universities. It must also focus on training specialists to protect, maintain, and develop the region's marine bio-resources to increase the growth of the region's bioindustry.

Recycled aggregate is a valuable resource in Korea in lack of natural aggregate. Government recognizes the importance and suggests various policies enhancing its use for higher value-added application. Most of recycled aggregate produced currently in Korea, however, is applied for low value-added uses such as embankment, reclamation, etc. Its higher valued application such as for structural concrete is very limited. Although domestic manufacturing technology of recycled aggregate is at the world level, recycled aggregate is not applied for structural concrete. Primary reasons for the limited use of the recycled aggregate include bonded mortar and cracks occurred during crushing and hence it is very difficult to predict and control the quality of recycled aggregate concrete. This research intended to grasp combined characteristics of recycled aggregate, high early strength cement, maximum temperature and time duration of steam curing and then, analyze the effects of factors. Also, it suggested the method to improve field applicability of recycled aggregate concrete.

Synthetic fiber materials were developed due the desire of consumers for high-quality, high-performance and comfort. A high functionality of synthetic fiber can be obtained through surface treatment that can improve hydrophilic properties, color depth after dyeing and adhesion properties. These advantages create added-value. Hydrophobic properties are an important feature to create added-value (such as hydrophilic properties). One side processing is a method of imparting to contrary function on the front and rear side. In this study, fluorine-coated Nylon/PU blended fabric was treated on only one side with a low-temperature plasma treatment; subsequently, the contact angles decreased by increasing the time and intensity of the plasma treatment. The contact angle of the untreated surface and the treated surface was different. It a showed a difference in the properties of both surfaces. Tensile strength and stiffness decreased by increasing the time and intensity of the plasma treatment. However, plasma treatment did not significantly change the tensile strength and stiffness on both surfaces of the fabric. SEM photographs showed the surface of fluorine-coated fabric and the etching surface by using plasma treatment on the fabric. Plasma treatment was confirmed not to affect the physical properties of the fabric.
