In the past, purchasing limited products was nothing more than purchasing expensive luxury goods. However, the current 'Limited product purchase' is not just pay to ability, but the information to purchase the product are important factors. Therefore, this study aims to find out 1) the motivation to purchase limited edition products and 2) the effect of the motivation on the consumer's experience(price, intention to purchase). As a result, five major purchase motives(Conformity, Interest, Scarcity, Finance technology, Desire to concede) were found. Among them 'Interest' had a positive effect on the product purchase price, and 'Conformity' had a negative effect on the product price. Next, 'Interest' and 'Scarcity' had a positively significant effect on intention to purchase. Through this study, we were able to reveal in depth the actual purchase motives of consumers who are currently emerging as the main age group of the new consumption culture, and expect these purchase motives to be actively used in the new market such as resell markets.

According to the lack of specific research on small business, this study analyzed the effects of a limited edition marketing strategy in a small business, whereas many previous studies focused only on large businesses. The test was performed by releasing and selling a limited edition (LE) product of a small brand with annual sales of about $10,000, for a limited time (one week), alongside social network advertising on Instagram. As this strategy resulted in a 10 times increase in sales from the previous year, the author concluded that a limited edition marketing campaign can significantly improve brand awareness and increase sales in a small independent business as well as larger businesses.

This study looked into the scarcity effect based on the consumers' self-regulatory modes and determined the effect that such a regulatory mode and that quantity-scarcity messages would have on evaluations of fashion products. To that end, the study used a 2 (regulatory mode: assessment mode/locomotion mode)${\times}2$ (message type: quantity-scarcity message/non-scarcity message) between-subjects factorial design in which buying impulsiveness was presented as a mediator variable that showed differences in product evaluations depending on the message type and on the presence of a self-regulatory mode. The results of this study showed that locomotion-oriented consumers evaluated products more positively compared to assessment-oriented consumers when the quantity-scarcity message was presented. When a non-scarcity message was presented, no significant difference was observed in product evaluations based on the consumers' self-regulatory modes. In addition, buying impulsiveness in consumers served a mediator role in the evaluations of fashion products. The results of this study imply that a clear understanding of consumers is a prerequisite for maximizing the scarcity effect and that companies need to differentiate in terms of the way they use scarcity messages based on consumers' self-regulatory modes.

This study is aimed at developing a supply-demand model of wood products, and outlook for mid-term and long-term supply and demand for each products. The main wood products include sawnwood, plywood, particle board, fiberboard (MDF), and pulp. The partial equilibrium model is composed of supply function, import demand function, demand function, price relation function. With given parameters the outlook for year 2050 says that sawnwood, plywood, and fiberboard for domestic productions and imports are decreased. This may result from the increase of log prices from the inside and outside of the country because of the propensity for environment protection and the resource nationalism. On the other hand the supply of particle board and pulp will increase because they are made from wasted wood and chips.

This study aims to update the supply-demand model of wood products(FOSMO-2013) and to forecast mid and long run supply and demand for each products. The subjects of the study include sawnwood, plywood, particle board, fiberboard(MDF), and pulp. The updated partial equilibrium model is composed of supply function, import demand function, demand function, price relation function. The long run outlooks of world prices of wood and wood products are imported from the results of Buongiorno(2012). This study also adopt Buongiorno's scenarios, which includes three scenarios of IPCC(A1B, A2, B2) and the other one with assumption of increasing fuelwood consumption of A1B scenario. The result says that the domestic productions of wood products are expecting to decrease while the imports of them increase even there are some differences among the products as well as scenarios.

최근 자동차에 사용되는 조명은 LED가 주를 이루고 있다. 자동차 실내조명, 계기판 등에 사용되는 내부 조명의 경우 대부분 LED를 적용한 제품이며, 헤드램프, 후방 램프 및 방향 지시등과 같은 외부 조명의 경우도 LED로 교체되고 있다. 특히 LED 기반 헤드램프의 경우 과거 3500cc 이상 승용차 등에 한정되었으나 현재는 그 이하 레벨의 승용차 및 SUV 차량으로 범위가 빠르게 확산되고 있다. 고효율, 긴 수명 및 빠른 응답 속도가 장점인 LED를 차량용 조명 광원으로 사용함으로써 기존 할로겐램프나 HID 광원의 대체재로서의 전환이 활발히 이루어지고 있다. 할로겐램프의 경우 청색보다 적색 파장의 광량이 많은 관계로 황색에 가까운 백색을 보이며, HID 램프의 경우 할로겐램프보다는 백색 계열에 더 가깝다. 하지만 LED 램프는 파장의 순도가 높아 보다 완벽한 백색 구현이 가능하다. 또한 단순한 기능을 지닌 헤드램프에서 지능형 헤드램프로의 발전이 빠르게 이루어지고 있다. 이에 따른 LED의 수요 또한 증가할 것으로 예상된다. 향후 고효율 LED 소자의 개발과 함께 자동차용 LED 조명에 대한 적용은 급속도로 진행될 것으로 예상되며, 앞으로 자동차 조명 분야에서는 'LED 헤드램프/후미등 기술+IT 기술(센서+통신)'이 융합된 형태로 발전할 것이다. 본고에서는 LED 자동차 융합 기술 동향 및 전망에 대해 자세히 기술하였다.
