본 논문의 목적은 한국 석유화학산업의 글로벌가치사슬 내 위치 변화와 한국 석유화학산업의 특성의 관계를 살펴보는 것이다. 한국 석유화학산업은 1960년대 정부의 정책적 지원 하 빠르게 성장하였고, 1980년대 수출주도형 산업으로서 한국 국가경제발전의 핵심 기간산업이 되었다. 1980년 말부터 한국 석유화학산업은 민간 주도의 대규모 생산설비 확충을 바탕으로, 한국은 글로벌 석유화학산업의 주요 국가로 자리매김하였다. 국내 석유화학산업의 공간적 분포는 울산광역시, 여수시, 서산시를 중심으로 상당한 공간적 집중이 나타난다. 그러나 석유화학산업 내 부문별로 지역별 공간적 집중 정도는 차별적으로 나타난다. 국내 석유화학산업은 지역마다 경쟁력 강화를 위해 차별적인 전략을 취함으로써, 구조고도화 및 고부가가치 제품 생산으로 전환하고자 한다. 국가 수준의 석유화학산업 내 구조 변화는 한국 석유화학산업의 GVC 참여 구조 변화를 유발하였지만, 주요 경쟁국에 비해 국내 부가가치는 낮은 수준이다.

Timber is an eco-friendly material that is suitable for low carbon and green growth, and recently, studies on utilization and manufacture of timber are increasing. Thus, we need a stable supply of wood working materials for the formative element and widespread function of timber. It is necessary to develop the use of timber because it enhances the added value of this material by making the most of it. In this way, skin-timber is an appropriate material for life articles because skin-timber has a variety of functions including the ability for storage use, the beauty of structure, the ability to maintain heat and insulation, and the capability to control humidity. In this study, I developed household items using skin-timbers that are made up of circular columns and square columns of pine, larch, and yellow popular. The circular and square columns have an inner hole that is approximately 90% of the external structure's width. I intended for the concept of these designs to display creativity considering functionality and productivity. These items are life articles and furniture for modern people. They are eco-friendly products that are varnished with traditional lacquer and natural oil. According to the result of this study, skin-timbers are made of domestic pine, larch, and yellow popular and are resource of furniture, household items, and woodcraft. I believe skin-timber is not only a useful material for processability and design applicability, but it also has the capability to be a multifunctional and high value-added material. Also, if the standards, such as cortex thickness, outside diameter, and length, of skin-timber are producted diversely, I believe skin-timber can be have more the possibility of industrial products' development.

There are need to develop of merchandise of value added fresh ginseng because of high consciousness level of consumer and enlarge of markets for high quality products. The fresh ginseng after harvest was distributed to farmer partually but in general, it was to market by consigner or wholsaler directly after harvest. There were a high difference on storage period of fresh ginseng in different harvesting seasons. The reduction of value of commodities of fresh ginseng for storage period was caused by decomposition and tender of tissue. The storage temperature was under the freezing point and the packing method was sealing tightly by plastic film. As the quality of fresh ginseng was defined by naked eye, it was difficult to sort the quality of ginseng directly harvest.

Fast-grown wood generally contains a high proportion of juvenile wood that results in inferior dimensional stability and durability against biological deteriorations. In the present research, the Acacia mangium wood from plantation forests in Vietnam was treated with high temperature in air. The effects of heat treatment on physical properties of Acacia mangium wood, including mass loss (ML), water absorption (WA), water-repellent effectiveness (WRE) and anti-swelling efficiency (ASE) were examined. The results showed that the dimensional stability and the water-repellent effectiveness are increased by about 15-46% and 8-18%, respectively. However, the mass and dimension of wood are decreased. The results also indicated that both treatment temperature and treatment duration significantly affect the wood properties of Acacia mangium. It is thus concluded that heat treatment demonstrates an interesting potential to improve the wood quality of Acacia mangium for solid timber products. This technology provides an environmentally safe method of protecting sustainable common woods to give a new generation of value-added biomaterials with increased stability without the use of toxic chemicals.

Limestone is an important commodity in Philippines. Limestone has numerous uses that range from agricultural applications to building materials to medicines. Many limestone products require rock with specific physical and chemical characteristics. Most limestone is biochemical in origin meaning the calcium carbonate in the stone originated from shelled oceanic creatures. In this paper, we reported the natural sources of limestone, geological formation of limestone and the oyster shell waste in Cebu, Bantayan, Philippines were reported. Due to the mining or quarrying in Cebu, Bantayan, in a limestone area poses the threat of groundwater pollution (since limestone is a porous geologic formation with a high transmissivity). The other environmental issue is oyster shell waste. The oyster shell waste is the major source of limestone. We developed and applied appropriate technologies for the extraction of limestone from oyster shell waste and utilizes as high value added material.

삶의 질이 높아지고 상품의 미적가치가 강조되면서 상품을 디자인하는데 있어 소비자의 감성을 고려하는 경향이 커지고 있다. 상품의 구매요인이 제품의 기능 중심에서 감성 중심으로 이동함에 따라 스토리텔링의 중요성이 과거보다 더욱 부각되고 있다. 이에 본 논문에서는 스토리텔링을 적용한 감성마케팅 공예디자인 개발에 목적을 두고 스토리텔링 개념의 이해와 스토리텔링을 적용한 공예디자인 사례 분석을 하고 이를 바탕으로 도자접시에 설화인 별주부전의 이야기를 과거와 현재가 융합되어 위트 있게 변형되어진 내용으로 재구성하여 스토리가 담긴 공예품을 만들고자 하였다. 공예는 상품으로의 가치나 미적 가치에 용이한 분야로 디자인의 다양성과 독창성이 추구될 수 있는 무한한 잠재력을 지니고 있다. 이제 표현적 가치뿐 아니라 의미적 가치의 부여와 함께 소비자의 감성과 욕구 충족을 시켜주는 공예디자인 개발이 필요하며 본 연구가 공예산업이 좀 더 고부가가치 산업으로 자리매김 할 수 있는 토대에 활용 되었으면 한다.
