본 논문에서는 불매운동에 따른 스마트폰의 수출영향에 대해 알아보고자 한다. 2019년에 일본의 한국에 대한 수출규제로 일어난 한국의 불매운동에 대응하여 역으로 일본에서 한국제품 불매운동이 일어난 바 있다. 이 사례를 활용하여, 한국의 일본 수출에 얼마나 타격을 입었는지 살펴보기로 한다. 연구 과정 전반에 걸쳐 수출물품 중 스마트폰의 수출량과 시장 점유율의 변화추이를 살펴보면서 불매운동과 스마트폰의 수출의 상관관계를 알아보았다. 이를 통해 불매운동이 수출입에 미치는 영향과 극복방안을 모색해 볼 수 있는 기회가 됐으면 한다.

SWOT model was used to develop strategies for the Korean construction firms in entering the global construction market. Literature review, official statistics survey and other research methods were utilized in order to extract internal and external environmental factors of both the firm and local area. By extracting strength, weakness, opportunity and threat factors, a total of 12 strategies were produced: SO (Strengths-Opportunities), ST (Strengths-Threats), WT (Weaknesses-Threats), and WO (Weaknesses-Opportunities). The result of the study can be utilized as a basic data in developing a strategy for the Korean construction firms to penetrate into the global construction market.

본 연구는 코로나-19 이후로 다시 활성화된 해외여행과 관련된 정보를 데이터베이스화해 정리하고, 폭발적으로 늘어난 여행객들을 위한 여행지 추천을 제시하였다. 또한 여행객들만이 아닌 여행사들을 위해 여행객들의 정보 역시 데이터베이스화하여 여행지 상품 수요조사 등에 사용할 수 있도록 하였다. 코로나-19로 인해 각국의 입국 정책은 다양해졌고, 해외여행이 단절된 기간 동안 소비자들은 여행에 대한 최신 정보를 계속해서 접하지 못했다. 그래서 이 데이터를 통해 소비자들의 수요에 맞는 여행지를 추천하고, 여행사들은 소비자들의 필요를 확인할 수 있을 것으로 사료된다.

In the environment of protectionism and bilateral trade agreements, Korea has promoted the conclusion of FTAs for its export-oriented trading policy, and 16 FTAs have entered into force at present. The main goal of this paper is to introduce the ISI system and its benefits and to extend the preferential rule of origin regime by using the Integrated Sourcing Initiative in the U.S. Code of Federal Regulations. The ISI illustrates with impressive clarity the fact that it considered as a tool of expanding the geographic limit of states and maximizing the global sourcing strategy of multinational corporations, allowing the developing countries to gain access to the market of developed ones that avoid the complexity and costs of many rules of origin regimes. This paper utilizes the literature research and analyzes a case study of FTAs which have adopted the ISI system. In conclusion, it presents several implications of additional measures to satisfy rules of origin in Korea's existing FTAs relating to the global supply chain strategy.

During crop disease surveys in 2019 and 2021, we observed gray mold symptoms on the leaves of wasabi (Eutrema japonicum) plants grown in vinyl greenhouses in Taebaek and Pyeongchang, Gangwon Province, Korea. The symptoms appeared at the edges of the leaves, where the infected areas turned black and rotted, and many gray molds formed on the lesions. The incidence of gray mold on the leaves in the vinyl greenhouses at the two locations ranged from 1 to 30%. Four fungal isolates were obtained from leaf lesions and identified as Botrytis cinerea based on morphological characteristics and phylogenetic analysis. Two isolates of B. cinerea were used for pathogenicity tests on the leaves of wasabi plants by artificial inoculation. The pathogenicity of the isolates was confirmed in leaves. The symptoms induced by the isolates were similar to those observed in wasabi leaves in the vinyl greenhouses investigated. This is the first report of B. cinerea causing gray mold in wasabi in Korea.

We propose a number-theory-based quantized mathematical optimization scheme for various NP-hard and similar problems. Conventional global optimization schemes, such as simulated and quantum annealing, assume stochastic properties that require multiple attempts. Although our quantization-based optimization proposal also depends on stochastic features (i.e., the white-noise hypothesis), it provides a more reliable optimization performance. Our numerical analysis equates quantization-based optimization to quantum annealing, and its quantization property effectively provides global optimization by decreasing the measure of the level sets associated with the objective function. Consequently, the proposed combinatorial optimization method allows the removal of the acceptance probability used in conventional heuristic algorithms to provide a more effective optimization. Numerical experiments show that the proposed algorithm determines the global optimum in less operational time than conventional schemes.
