Purpose - This paper explains why free trade agreements (FTAs) are more popular than customs unions (CUs) in respect of tariff coordination. Design/methodology - This paper employs an equilibrium theory of trade agreements with tariff coordination. I set up three-country partial equilibrium model with competing exporters. Domestic and exporting firms decide their optimal production under given tariffs and each country levies its tariff under the trade agreements. I found stability of implicit tariff coordination and preference of each country between an FTA and a CU. Findings - I demonstrate that two FTA members can keep their external tariffs higher than separately decided external tariffs by keeping the status-quo. This implicit tariff coordination can benefit each member through trade diversion. In a CU, each member country must have a common optimal external tariff and it must incur costs because each country may seek different external tariffs for their own national welfare. The benefit of implicit coordination in an FTA and the cost of explicit coordination in a CU account for the popularity of the FTA. Originality/value - This paper uses the idea of implicit tariff coordination in trade agreements. In a CU, tariff coordination is explicit and mandatory. All member countries must have a single common external tariff for each good. On the other hand, in an FTA, each country establishes its external tariff with the goal of maximizing its own welfare. However, each country can also coordinate "implicitly" by keeping the status-quo after establishing an FTA.

본 논문은 Holland 6각형 모형에서 내 외재적 직업가치를 가늠하는 축이 탐구형 진취형(IE)임을 검증하기 위해 직업카드분류150 검사에 참여한 19명 연구대상자의 Holland 6각형 모형과 내 외재적 직업가치를 분석하여 검증하였다. 분석 결과 첫째, 탐구형 진취형(IE) 축을 중심으로 Holland 6각형 모형이 예술형(A), 사회형(S) 쪽으로 치우쳐 있는 연구 집단은 내재적 직업가치를 나타내어 가설을 지지하였다. 둘째, 탐구형 진취형(IE) 축을 중심으로 6각형 모형이 현실형(R), 관습형(C) 쪽으로 치우쳐 있는 집단은 외재적 직업가치를 추구할 것이라고 한 가설은 기각되었다. 이는 유교문화권에서 정신문화적 가치를 추구하는 한국 특유의 문화적 맥락이 작용한 결과이며, Holland 6각형 모형이 정확하게 탐구형 진취형(IE) 축의 왼쪽에 분포되지 않은 면도 있다. 셋째, 양가적 직업가치의 집단은 탐구형 진취형(IE)축을 기준으로 Holland 6각형이 예술형(A), 사회형(S), 현실형(R), 관습형(C) 등에 걸쳐 나타낸다는 일부 가설을 지지하였다. 본 논문은 일부 가설이 기각되었음에도 불구하고 Holland 6각형 모형 중 탐구형 진취형(IE) 축이 가치를 구별하는 잣대라는 것을 처음 제시한 연구로서 Holland 6각형 모형이 직업선택 뿐만 아니라 직업가치를 예언할 수 있음을 제시하여 Holland 이론의 저변 확대를 꾀하였고, 직업학의 기초자료를 제공하는데 그 의의가 있다.

비즈니스 모델 혁신이란 비즈니스 모델을 구성하는 여러 가지 요소를 다각도에서 변형시켜 차별화되는 가치를 창출해내는 것으로 기업의 외부 환경이나 내부 환경 중 어느 한 쪽에 집중하기 보다는 내부의 자원과 역량, 그리고 외부 환경이 만나는 곳에서 최적의 선택을 하는 것이다. 그러나 비즈니스 모델 혁신에 대한 명확한 정의가 없고, 핵심 비즈니스 모델을 잘 활용하지 못하는 관계로 기업이 비즈니스 모델 혁신을 통해 성장한다는 것은 매우 어려운 일이다. 본 논문에서는 비즈니스 모델 혁신에 대한 정의를 체계적으로 정리하고, 비즈니스 모델 혁신이 필요한 시기가 언제인지, 어떠한 유형의 비즈니스 모델 혁신이 있는지를 몇 가지 사례를 통해 살펴보았다. 기업의 가치 제안, 가치사슬과 가치네트워크를 통한 가치 창출과 수익모델의 혁신 사례를 통해 비즈니스 모델 혁신이라는 다소 추상적인 개념을 좀 더 친숙하게 접근하였다. 마지막으로, 이미 성공한 기업 역시 비즈니스모델 혁신과 적응우위 강화로 급변하는 시장 환경에서 새로운 가치를 창출할 수 있음을 사례분석을 통해 입증하였다.

This study intended to determine how price-ending types used for menu products affected consumers' price evaluation and value perception and such behavioral intentions as purchase intention and search intention. The collected data went through statistical processing, including frequency analysis, factor analysis, T-test and ANOVA using an $SPSS/PC^+$ 12.0 statistical package. The results can be summarized as follows: First, as for differences in internal reference price by ending, internal reference price was lower if menu ending was an odd number than it was an even number, which indicates that consumers tend to consider the price of the menu products to be lower if the ending of menu products is an odd number. Second, menu price-ending was found to have significant differences on consumers' purchase intention, search intention, and value perception. But the results of two-way ANOVA showed that price ending by restaurant types had no effect on consumers' search intention and restaurant type. This study suggested a desirable external reference price-ending type for menu products as one of sales promotion strategies to menu products planners and drew up a concrete plan to determine which price-ending type is useful by consumers' personal properties.

Objectives The present study aimed to investigate the effects of acupuncture and herbal external preparation on wound healing procedure in a deep partial thickness burn model in rats. Methods A total of 40 male Sprague-Dawley rats were allocated into four groups with an equal number in each group: acupuncture treatment group, herbal external perparation group, Silver sulfadiazine dressing group and control group. We describe the effect of acupuncture and herbal external preparation on morphologic and histologic changes, epithelial growth factor (EGF), hematological value of the deep partial thickness burn wound in rats. Results At 21th day after wounding the wound size in acupuncture treat group and herbal external preparation group were decreased more significantly compared to control group. In addition, epidermal regeneration on acupuncture treatment was than other treatment and control group in histological finding. Hematological findings revealed that acupuncture treatment group and herbal external prepartion group was more effective than control group in reducing inflammation response induced by burn. In acupuncture treated group, neutrophil and leukocyte level were significantly decreased compared to other treatment group. Also, this study showed that EGF was obviously expressed in nascent tissue when wounds were treated with the acupuncture and herbal external preparation after injury. In particular, acupuncture treatment group had a significant increase of EGF expression in burn wound healing area when compared with the other treatment groups. Conclusions These findings suggest that acupuncture and herbal external prepration may improve burn wound healing through decreasing inflammatory reaction, increasing tissue regeneration and expression of EGF. Moreover, acupuncture treatment could be more effective in comparison with Silver sulfadiazine dressing.

The reponse of the angled two-strip transmission lines illuminated by an external electromagnetic field is estimated by using the circuit concept approach. Calculated terminal voltages reveal convergence to a fixed value as the number of discretization increases. The amplitude patterns of two terminal voltages to all the direction and polarization of the incident field are also calculated.

The aim of this study is to formulate a trust-based business model of Internet services in so called the "trust economy." For it, firstly concepts of trust and trust economy are discussed. Then, we present previous literatures' review of trust in social science prism and trust economy in economic prism. This study classified the literatures' stances with two viewpoints of the 'system' and the 'user'. With this backdrop, we discuss three contradictory stances: Internal optimization vs. external interaction, personal data control vs. orchestration, and end-user vs. ecosystem value. In the result, we formulate a trust-based business model framework with three trust issues in user perspective and suggests three strategic directions related three issues along with representative use cases.
