  • In this paper, we suggest the tracking method of moving multi-objects in maritime environments. The image acquisition is conducted using IR(InfraRed) camera sensors on an airborne platform. Under the circumstance of maritime, the qualities of IR images can be significantly degraded due to the clutter influence, which directly gives rise to a tracking loss problem. In order to reduce the effects from the clutters, we introduce a technical approach under Man-In-The-Loop(MITL) system for enhancing the tracking performance. To demonstrate the robustness of the proposed approach based on VTG(Valid Tracking Gate), the simulations are conducted utilizing the airborne IR video sequences: Then, the tracking performances are compared with the existing Kalman Filter tracking techniques.

  • Recent changes in the construction method of piles to minimize noise, along with the development of high-strength reinforcement, have provided an economical high performance RC pile development to compensate for the disadvantages of existing PHC piles. In this study, a methodology for the development of cross - section details of high performance RC piles of various performances is presented by freely applying high strength steel and concrete. This study suggested a technique for calculating bending moments for a given axial force corresponding to the allowable crack widths and this can be used for serviceablity check. In calculating the design shear force, the existing design equation applicable to the rectangular or the I section was modified to be applicable to the hollow circular section. In particular, in the limit state design method, the shear force is calculated in proportion to the axial force, and the procedure for calculating PV diagram is established. Last, the section details are determined through PM diagrams that they have the similar flexural and axial-flexural performances of the PHC pile A, B and C types with a diameter of 500 mm. To facilitate the application of the selected standard sections to the practical tasks, the design PM diagram and design shear forces are proposed in accordance with the strength design method and limit state design method.

  • Purpose - Multi-National Enterprises (MNEs) tend to face a high level of institutional pressures in regions with high institutional development level. When complying with institutional pressures, firms try to make decisions to maximize profit while minimizing the risks to them. The purpose of this study is to investigate the influence of the institutional development level on institutional compliance timing by MNEs and the relationship between compliance speed and corporate performance. Design/methodology - The research focuses on three main variables, which are the institutional development level (as a determination of the institutional pressure level), the firm's compliance speed (as a determination of the compliance timing), and the firm's financial performance (as a determination of the corporate performance). We collected 19,869 firm-level data from CSMAR (the China Stock Market and Accounting Research), 6,922 CSR data from RKS (the Rankins CSR Ratings), and province and city-level data from the NERIM (National Economic Research Institute Index of Marketization) and NBSC (National Bureau of Statistics of China). The firms in China were chosen for analysis, and the analysis period was from 2008 to 2017. Random Effects GLS Regression was used to test the relationships among the variables. Findings - This study examined the effect of the institutional development level on the firm's compliance speed, together with the effect of compliance speed on the firm's financial performance of the MNEs in China. We found that the institutional development level positively influenced firms' financial performances, which means the firms' financial performances are better in the region with a high institutional development level. The compliance speed of institutional practice by firms was faster in the higher level of institutional development. However, the firm's delayed compliance led to better financial performance. Originality/value - Studies in the resource dependence view of Institutional Theory often fall short in understanding the theory by overlooking the firm's active decision-making. Thus, the findings do not present a full scope of corporate performance in this regard. This study not only found a way to test the role of a firm's independent decision-making (i.e., compliance timing) when facing the institutional pressure but also prove the significant role of the compliance timing on corporate performance. Also, we were able to test the effect of institutional development level, controlling location-specific variables because we used CSR performance data for MNEs operating in China. Lastly, by doing the above, the findings of this study suggest practical implications to the industry practitioners in MNEs.

  • 본 연구는 소상공인의 대부분을 차지하는 자영업자와 가맹점사업자의 사업성과 및 사회경제적 사회심리적 특성에서의 차이를 비교분석하고 있다. 가맹점사업자는 가맹사업이라는 사업양식을 활용하고 있고, 사업파트너인 가맹본부가 요구하는 일정한 기준을 충족시켜야 하기때문에 이러한 조건으로부터 자유로운 자영업자와 상이한 특성을 지닐 것으로 기대되었다. 2011년 전국소상공인 실태조사에 포함된 가맹점사업자 424명과 자영업자 5,690명으로부터 수집한 서베이자료에 대한 분석 결과, 가맹점사업자는 자영업자와 비교할 때 재정능력, 사업 경험과 관리능력, 인구통계특성, 정보탐색 노력, 심리적 특성, 사업성과, 사업애로사항에 있어 통계적으로 유의미한 차이가 있는 것으로 나타났다. 또한 가맹점사업자와 자영업자의 사업성과에 이들 변수가 미치는 영향에 있어서도 상당한 차이가 있는 것으로 나타났다. 가맹점사업자와 자영업자가 서로 다른 특성을 지니고 있고, 이들 특성이 사업성과에 미치는 영향이 다르다는 것은 이들의 정부에 대한 정책수요가 이질적이고 정책효과도 두 집단 간에 상이할 수 있음을 시사한다. 이를 근거로 본 연구는 향후 정부의 소상공인 지원정책이 가맹점사업자와 자영업자를 구분하여 수행되는 것이 바람직한 것으로 주장하고 있다. 또한 가맹점사업자의 성과를 제고하기 위해 가맹본부가 가맹점을 선택할 때 중요하게 고려하여야 할 사업자 특성과 관련한 경영상 시사점도 제시하고 있다. 본 연구는 몇 가지 이론 및 방법론 상한계를 지니고 있으며 따라서 이를 보완하기 위한 향후 연구방향도 제시하고 있다.

  • 본 연구는 지역사회 비영리 공연 관람객의 동기와 지역사회만족도 간 매개효과로써 공연만족도와 관객충성도를 살펴보는 것이다. 동기는 내적/외적으로 구분하여 관객의 심층적인 욕구를 알아보았다. 데이터 구축을 위해 지난 1년간 제주지역 비영리 공연 관람 경험이 있는 관람객을 대상으로 설문조사를 실시하였다. 최종적으로 363명에 대한 설문자료를 분석자료로 사용하였다. 분석결과, 내적/외적 동기 수준이 높을수록 대체로 공연에 대한 만족과 충성도는 높게 나타났지만(H1, H2, H3), 외적동기가 충성도에 직접적인 영향을 미치지 않았다(H4). 그러나 2가지 동기 모두 공연만족도를 매개하여 충성도에 긍정적인 영향을 미치는 것으로 확인되었다(H5,H8). 공연에 대한 만족이 지역사회만족도에 직접적인 영향을 미치지 않았지만(H6), 관객충성도는 지역사회만족도에 긍정적인 영향을 미치는 것을 확인하였다(H7). 관람동기의 경우, 지역사회만족도 간의 관계에서 공연만족도는 매개효과를 보이지 않았다(H9). 관객충성도의 경우 내적동기는 매개효과를 보였지만 외적동기는 매개효과를 보이지 않았다(H10). 동기-만족도-충성도-지역사회만족도는 순차적인 단계의 프로세스를 보였다(H11). 결과적으로, 지역주민들이 비영리 공연에 관심을 가지고 참여한다면 해당 지역에 대한 긍정적인 인식을 갖게 된다. 따라서 지역 차원에서 제공되는 공연예술은 지역 발전의 중요한 요소로써 인식되어야 한다. 이러한 결과를 바탕으로 본 연구와 관련된 이론적, 실무적 시사점을 논의하였다.

  • We have studied on optical properties of advanced S-IPS with a fine pitch electrode and a new finger design. Transmittance of panel increases with decreasing of width and angle of finger electrode. In order to improve transmittance, fine pitch electrode of ${\sim}2{\mu}m$ and rubbing angle of 10 degree have been adopted. Various optical performances are defined as the function of finger design and field intensify across the IPS pixel electrodes. We have developed the advanced electrode structures with a high performance. As a result, the optical properties of 42" full HD with 120Hz frequency shows high transmittance over 5%, contrast ratio of 1800:1, gray-to-gray response time of 4.4ms, respectively. And also we have studied that the moving picture quality of IPS LCD is related with design parameters of IPS cells and finger shape.

  • The support structure of an optical mirror system is the one of the important design elements because the one affects the optical aberrations of the mirror surface. In this paper, Lagrange equation of the moving body of the fast steering mirror system(FSM) has been formulated to use with optimization design. Major goals for optimization are to assign the reasonably flexible stiffness to the structure and to enhance the first natural frequency of the mirror and support system in aid of more affordable control bandwidth for the FSM. Pursuing these purposes with the proposed method, the finite element analysis(FEA), optimization technique and the Zernike polynomial estimation are used for the design effects. It is concluded that the proposed approach for design well guides toward the desired design goals with regards to both structural and optical performances.

  • The purpose of this study is to figure out the current condition of local governments (Si or Gun) to implement rural development policy in the face of the central government's drive for increasing devolution. Since late 1990s or early 2000s when scope of rural policy began to expand quantitatively, there has been considerable increase in rural residents' participation into community projects as a whole. Nevertheless, there exists regional differentiation in local governments' efforts to systematically support rural development projects (CRDP: Comprehensive Rural Development Programme) and community activities by setting up intermediary organizations or hiring rural development professionals in a public office. According to this survey on local government officials, regions that have made such efforts to support rural policy at a local level, show more advanced level of institutional capacity than other regions in local decision making process for CRDP, role of strategic rural developmental plans, vitality of community actors, etc. In the era of increasing devolution, these differences can be expected to result in diverging performances of each area in regionalized rural policy. The central government needs to introduce EU's LEADER-type rural development programmes to support community acitivities by various local actors and at the same time promote local governance building for rural policy, adopting institutional rewarding system such as rural planning contract.
