The collaboration between businesses in a demand chain has three layers: Integration, Exchange, and Synchronize. The latter the layer is, the stronger the collaboration gets. This paper investigated drivers influencing intelligent demand chain integration strategy (supply integration, demand integration, demand chain integration) in Korea manufacturing and services. The drivers are classified into two types: rational efficiency driven and bandwagon driven. We find tile differences in the characteristics of drivers affecting the strategies. Besides, this study suggests the better integration strategy for Korea firms. In conclusion it says that demand integration strategy is chosen to improve efficiency, whereas supply integration strategy is influenced by external pressure.

Pollinators are organisms that carry out the pollination process of plants and include Hymenoptera, Lepidoptera, Diptera, and Coleoptera. Among them, bees not only pollinate plants but also improve urban green spaces damaged by land use changes, providing a habitat and food for birds and insects. Today, however, the number of pollinating plants is decreasing due to issues such as early flowering due to climate change, fragmentation of green spaces due to urbanization, and pesticide use, which in turn leads to a decline in bee populations. The decline of bee populations directly translates into problems, such as reduced biodiversity in cities and decreased food production. Urban beekeeping has been proposed as a strategy to address the decline of bee populations. However, there is a problem asurban beekeeping strategies are proposed without considering the complex structure of the socio-ecological system consisting of bees foraging and pollination activities and are therefore unsustainable. Therefore, this study aims to analyze the socio-ecological system of honeybees, which are pollinators, structurally using system thinking and propose a green space planning strategy to revitalize urban beekeeping. For this study, previous studies that centered on the social and ecological system of bees in cities were collected and reviewed to establish the system area and derive the main variables for creating a causal loop diagram. Second, the ecological structure of bees' foraging and pollination activities and the structure of bees' ecological system in the city were analyzed, as was the social-ecological system structure of urban beekeeping by creating an individual causal loop diagram. Finally, the socio-ecological system structure of honey bees was analyzed from a holistic perspective through the creation of an integrated causal loop diagram. Citizen participation programs, local government investment, and the creation of urban parks and green spaces in idle spaces were suggestedas green space planning strategies to revitalize urban beekeeping. The results of this study differ from previous studies in that the ecological structure of bees and the social structure of urban beekeeping were analyzed from a holistic perspective using systems thinking to propose strategies, policy recommendations, and implications for introducing sustainable urban beekeeping.

기업의 성과관리와 성과평가 분야에서 성과지표의 분류는 조직의 내부 구성관계 즉, 수직적 (vertical) 구조(전사-본부-팀)와 수평적 (horizontal) 구조(본부와 본부 혹은 팀과 팀간)의 공유에 따라 구분될 수 있으나 기존 연구(Lipe & Salterio 2000, Dilla & Stcinbart 2005)에서는 공통지표와 고유지표라고 하는 수평적인 측면만이 고려되고 수직적인 측면은 고려되지 않았다는 한계가 있다. 조직의 성과가 향상되기 위해서는 하부조직이 전사 전략에 집중 할 필요가 있으며 이를 위하여 전사의 비전을 위한 전략목표달성에 기여한 정도를 측정하여 보상과 연계하는 것은 성과관리제도가 추구하는 기본 방향이며 도입목적이기도 하다. 그런데 선행 연구에서 밝혀지지 않은 조직구성 관계의 수직적 측면에서 전사지표의 정렬(Alignment)을 통한 공유와 할당(Cascading)된 지표의 가중치를 고려해 볼 때 고유지표는 재 정의하여 세분화 할 필요가 있다는 점이다. 즉, 특정 부서의 지표 중에는 전사 혹은 상위부서에 반영되어 공유하고 있는 고유지표(이하 공유지표)와 전사 혹은 상위부서에는 반영되지 않고 해당 부서만 독점하고 있는 순수한 고유지표(이하 고유지표$^{1}$)로 구분되어야 하며 공유지표와 고유지표의 분류에 따라 가중치 설정이 달라져야 한다는 주장이 그것이다. 따라서 본 연구의 목적은 조직이 성과를 공정하게 평가하고 하부조직이 전사전략에 집중하도록 하기 위해 공통지표와 고유지표를 사용하고 있는데(Dilla & Steinbart 2005), 고유지표를 공유지표와 고유지표로 재 정의하고 분류하여 관리 할 필요가 있다는 점과 각각의 지표 분류에 따라 가중치 설정에 차이가 있는지에 대한 유의성을 검증해 보고자 한다.

The purpose of this study is to extract the factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction and analyze the structural associations between them. Factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction were extracted through exploratory factor analysis (EFA). Based on the findings of EFA, the questionnaire has been further analyzed using confirmatory factor analysis (CFA). In addition, based on the factor structure identified through factor analysis, we comprehensively analyzed the image of science teacher desired by elementary school students in inquiry-based instruction. As a result of EFA, five factors were identified which compose the image of science teacher desired by elementary school students in inquiry-based instruction: namely, teaching strategy, assessment strategy, prior guidance, understanding students, learning development. The CFA results showed a relatively strong correlation between teaching strategy and learning development, teaching strategy and understanding students. As a result of a comprehensive review of students' perception of the image of science teachers in inquiry-based instruction based on the extracted factor structure, students perceived that it is important for science teachers to run inquiry-based instruction by reflecting their understanding of students. Students also perceived importantly that science teachers run inquiry-based instruction using effective teaching strategies and proper evaluation strategies.

This study examines dynamics in election news making. It is important to understand when and how news media produce election news in order to grasp news making and voting behavior. The news media sometimes make election news by focusing on issues and policies. Often they frame elections as a game and focus on election strategies while covering elections. This article argues that as time goes by during the election period, the number of policy news tends to decrease while the frequency of strategic news is likely to increase. Also, TV's and newspapers show distinctive patterns of election news making. In order to examine the arguments, this study categorizes election news stories into policy and strategic news stories produced during the 2020 Korean congressional elections and constructs daily time-series data of them. The results of structural break and regression analyses partially support the arguments.

This study reviews previous studies about the effects of RFID capabilities on strategic supply chain competence and business performance in the Chinese context. This study introduces a new perspective that measures the degree to which RFID capability levels contribute to business performance. Such an assumption is based on the fact that companies build their own capabilities through RFID capabilities and that these capabilities provide a competitive advantage for enterprises. Data on all sorts of logistics, distribution, and manufacturing companies that introduced RFID system in China were collected for data analysis. This study analyzes the structural equation modeling using Smart-PLS 2.0 program. This study confirms that internal reliability, convergent validity, and discriminant validity are satisfied. The hypothesis test result on the relationship between RFID capacity and strategic supply chain competence and strategic supply chain competence and company results is partially adopted. This study aids in establishing a RFID system construction strategy to enhance supply chain competence by suggesting guidelines for the successful introduction of RFID system through identifying the causal relationship between RFID capacity and strategic supply chain competence. This study also suggests the influence of RFID competency on visibility, agility, flexibility, and collaborations.

LL (Leased Line service) is a facility-based service as a traditional business data service, but new competition services, such as FR (Frame Relay), VPN (Virtual Private Network), and ATM (Asynchronous Transfer Mode), are value-added services. Because of different service classifications, it is hard to gather necessary data for the service providers to plan their market strategies and regulations and policies are also applied asymmetrically to each service provider. Therefore an appropriate market classification is required for the business data services. After various methods of market classification are reviewed, the Hendry model is selected in this paper to analyze substitution-degree among brands or among services. Since the structure of virtual competitions is required for the Hendry model to be applied to data service market, the market is analyzed first by the well-known Porter's model. By the analysis of Porter's model, two virtual competition structures are set up - one is for the competitions among leased line service providers, and the other is for the competitions among business data services such as LL, FR, VPN and ATM. After the Hendry model is applied to each competition structure, it is confirmed that 7 LL service providers do not compete directly, but 2 sub-markets exist for the LL service provisions. However, it is shown that 4 business data services compete directly. Using the Switching Probability Matrix from Hendry model, future market shares of LL service providers and market shares of business data services are forecasted. These empirical results are helpful for service providers to set competitive strategies with the minimization of cannibalization effect and they can easily and efficiently predict their market demands.

우리나라 기계공업은 해방후 40 여년의 역사를 갖고 있으나 실질적으로 그 면모를 갖춘 시기는 60 년대 중반부터라고 할 수 있다. 이렇듯 일천한 경험과 미약한 기술축적에도 불구하고 오늘날과 같은 괄목할 만한 성장을 이룰 수 있었음은 매우 경이로운 사실이라 하겠다. 그러나 돌이켜보건대 우리나라 기계공업은 급속한 산업의 근대화 와중에서 체계적인 발전 방향없이 양적팽창 을 거듭해온 관계로 많은 구조적 문제를 안고 있다. 다만 1973 년 중화학공업선언, 1974 년 창원기계 공업기지건설, 1979 년 기술도입 자유화등 일련의 기반을 구축하는 데는 성공하였으나 외형적 성장 전략으로 인한 기초부품산업의 상대적인 위약과 기술의 해외의존 심화 및 투자배분의 불균형 등은 오늘날 기계공업계가 해결해야할 1차적인 숙제가 되고 있다. 즉 이러한 기계공업의 발전과정에서 비롯된 허약점은 제품의 국제 경쟁력 제고에 커다란 장애요인이 되고 있으므로 향후 우리경제의 질적, 양적 발전에 일익을 담당하기 위해서는 현 기계공업에 대한 냉철한 분석과 반성이 있어야 할 것이다.
