본 연구는 스타트업 투자성과와 연계된 창업가 역량, 재무정보 등 정량데이터를 기반으로 스타트업 투자자들의 투자결정요인을 분석하였다. 주요 실증결과는 다음과 같다. 첫째, 창업 초기 종업원 수가 많고, 최고경영자의 지분비율이 높을수록 투자승인 확률이 높게 나타났다. 둘째, 재무적 특성에서는 기업의 매출액 규모가 작을수록 투자승인 확률이 높게 나타났다. 이러한 결과는 스타트업의 경우, 기업의 단기성과보다는 투자 결정에 있어 미래가치 혹은 다른 정성적인 요인이 더 고려된다는 점을 보여준다. 셋째, 창업가 특성에서는 CEO 교육수준(학력)이 높을수록 투자승인 확률이 높게 나타났다. 즉, 창업자의 학력은 성공적인 투자 여부에 핵심적인 변수이고 이것은 선행연구의 결과와 다르지 않았다. 또한, 학력과 투자유치의 연관성은 창업 3년 미만 스타트업에서 상대적으로 강하게 나타났다. 선행연구에서 투자정보공개, 관련 데이터 확보의 어려움으로 스타트업 투자에 관한 정량적 실증연구가 거의 진행되지 못한 점을 고려한다면, 본 연구는 설문조사 방식을 뛰어넘어 국내 초기 창업기업만을 대상으로 성공적인 투자유치와 연계된 스타트업의 평가요인을 정량적으로 분석했다는 점에서 중요한 의의를 갖는다.

시스템 다이내믹스 연구에 있어서 피드백 루프는 시스템의 구조와 행태를 연결시키는 핵심적인 개념적 도구이다. 특히 여러 개의 피드백 루프로 구성된 복잡한 시스템에 있어서, 지배적 피드백 루프(dominant feedback loop) 및 그 전환(shift)은 시스템의 행태를 결정짓는 구조적 원인을 제공한다. 그러나 지배적 피드백 루프에 대한 연구는 아직까지 그 발견방법에 관한 알고리즘 연구에 머물러 있는 상태이다. 지배적 피드백 루프는 시스템의 급격한 변화를 예상하는 단초가 된다는 점에서, 지배적 피드백 루프를 어떻게 인식할 것이냐는 정부의 정책결정에 있어서나 기업의 의사결정에 있어서 중요한 문제라고 할 수 있다. 본 논문에서는 지배적 피드백 루프 및 그 전환에 대한 의사결정자의 인식에 관하여 살펴보고 어떠한 인지적 편향이 있는지에 관하여 검토하고자 한다.

The position fixing is the first essential in any offshore activity. At sea, position is almost always related to fixed points on land. The traditional method of the position fixing of a vessel is by double horizontal sextant angles observed between three fixed stations, plotted as a graphical resection using station pointers. Of recent, offshore fixing progresses in simple object of navigation and fishery, and it is tending to use and develop ocean and coast compositly. Therefore, we compared and analyzed deviation of fixed point for more accurate offshore fixing. This paper used only navigation instruments such as NNSS, Loran-C, Omega involved in long range and world wide among the methods of E. P. F. (Electromagnetic Position Fixing).

Nowadays the considerable improvements, not only in photogrammetric equipment but also in adjustment methods have led to a high accuracy of Aerial Triangulation and reach the step to obtain A.T. technique that uses Global Position System without ground control survery. The enterance of analytical plotter have made considerable development both in accuracy and in efficiency and improved working environment of A.T. by the combination of On-Line Analytical Plotting System. In this paper, in A.T., with using of analytical polotter, aims to improve the acccuracy in coordinates determination of low level control point. The result shows that in case of A.T. with analytical plotter AVIOLYT BC2, the accuracy of control points improves to 7% in planimetry and to 40% in height compared to A.T. with precision plotter Autograph A-8.

This study aims to improve the positioning accuracy by analizing the accuracys of three dimensional positioning according to various data types and preprocessing levels of SPOT imagery and the acquisition method for ground control points, and to develop the three dimensional positioning algorithm and program. In this study, the optimum polynomials of exterior orientation parameters according to each preprocessing levels (level 1B; 15 variables, level 1AP, 1A; 12 variables) are determined. As a results, the accuracy of level lAP is the best in the results of analysis about the accuracy of positioning, but level 1A which is digital image data form also shows similar positioning accuracy. Also, in level 1A image which have different acquisition method for ground control points, the accuracy of three dimensional positioning is highly improved. But, in case of low accuracy of ground control points, only introduction of additional parameters does not effect to the improvement of accuracy. Therefore simultaneous adjustment including blunder detection method should be adopted.

Why the National Assembly of Korea shows the serious disagreements or arguments in its operation? Regarding the question, this study pays attention to the perceptual differences among the parties for the structure of collective decision-making in the National Assembly of Korea. In addition, this study asserts that deepens the conflicts and the distrust in it. To be more specific, this study discusses about the optimal model for collective decision-making in legislative politics based on Buchanan and Tullock's opinion about it. And then, the trust in legislature forms the basis that makes it possible to respect the will of majority and protect the right of minority. The main reason that can't make the collective decision-making optimally in the National Assembly of Korea is to fight each other without the consensus about it. In this vein, making the collective decision-making optimally and recovering the trust among the parties are necessary to adopt a more consensual system. It will be helpful to prevent the use of noninstitutional means like the outside struggles or physical resistances in the National Assembly of Korea.

This study was pre-experimental research designed to compare the differences between pre-and post-program on nursing student's career maturity, career decision-making self-efficacy and employment stress. The subjects were 247 junior-year students in nursing school. Mean value for career maturity was from 2.59 to 2.57, career decision-making self-efficacy from score 3.44 to 3.65 in average(t=8.67, p<.001), and employment stress from score 2.94 to 2.83 in average(t=-3.46, p<.001). Career maturity was significantly different according to high employment rate(F=3.15, p=.025), high career preparation(F=2.69, p=.032). Career decision-making self-efficacy and employment stress was significantly different according to high career preparation(F=1.22, p=.031) and low career preparation(F=2.52, p=.030).

It is necessary to determine accurate 3-dimensional coordinates of the building corner points that could be control or check points in order to verify the accuracy of 3D digital maps in the near future. The usual process of obtaining the coordinates of the building corner points is to set up the ground control points with a GPS and then to practice terrestrial survey such as distance or angle measurements. However, since an error in the ground control points can be propagated through the terrestrial survey into the final coordinates of the buildings, accurately should be considered as much as possible. The actual effect of the GPS-derived ground control point error on the estimates of the unknowns through the terrestrial survey is mathematically analyzed, and the simulation data is tested numerically. The error of the ground control points is tested in the cases of 1-4 cm for the horizontal components and 2-8 cm for the vertical component. The vertical component error is assigned twice the horizontal ones because of the characteristics of the GPS survey. The distance measurement is assumed for convenience and the precision of the estimated coordinates of the building corner points is almost linearly increased according to the errors of the ground control points. In addition, the final estimates themselves can vary by the simulated random errors depending on the precision of the survey instrument, but the precision of the estimates is almost independent of survey accuracy.

The purpose of this study was to examine the influence of critical thinking, clinical decision making and job satisfaction of 132 dental hygienists. The data was collected from 1st May to 31th October, 2012 in Ulsan, Pusan and Gyeongsangnam-do areas. The majority participants were female, 30.6 years old, graduate diploma course of dental hygienist, and working in dental clinics. In critical thinking, truth-seeking was highest score, 3.36 but maturity was lowest score, 3.00. In clinical decision making, canvassing of objectives & values was highest score 3.39, but search for alternatives or options was lowest score, 3.10. In job satisfaction, professional status was highest score 3.20, but incomes & promotion was lowest score 2.84. In correlation between general characteristics and critical thinking, there was significantly different in religion, education status, total working period and working areas. There was significantly different with religion and education status in clinical decision making, And There was significantly different with religion and education status, total working period, and working areas in job satisfaction. Critical thinking, clinical decision making and job satisfaction was positive relationship. To improve professional competence and job satisfaction of dental hygienist it need to use actively the critical thinking and clinical decision making. And it need to prepare the education and strategy to increase the job satisfaction of dental hygienist.
