The year 1997 was when Korean Journal of Public Relations Research started to publish research articles. This study addresses the issue of theories in Korean public relations research. A total of 166 research papers are analyzed to see characteristics and changes during 2003-2012. Through this meta analysis, the researcher tries to see the big picture and discusses the right direction for the future of the public relations in many ways. Three different groupings were adopted to classify theories in the 10 year perion - 1. origins of theories(public relations field, related neighbor field, distant field), 2. target of analysis(individual, organization, society), 3. level of approach (systematic pluralistic, rhetorical, critical approach). According to the findings, though getting better, it was 'cold season' in public relations research because theories utilized in Korean public relations research were not very excellent qualitatively and qualitatively. Interdisciplinary approach is discussed.

본 연구는 이론적 모형전개와 자료분석의 두 측면에서 정리될 수 있다. 우선 경제학자들에게 널리 받아들여지고 있는 성장이론을 원용하여 지가의 결정과정에 대한 동태적이고 일반균형적인 접근방식을 제공하고자 하였다. 이를 통해 지가의 높고 낮음을 평가할 때 그 기준이 될 수 있는 변수로는 국민소득 대비 지가총액의 비율을 살펴보는 것이 합리화될 수 있음을 설명하였다. 이와 같은 이론적 배경하에서 우리나라의 경우 이 비율이 선진국 수준(1 내외)에 비하여는 아직도 상당히 높은 상태(3~4 수준)에 머물러 있는 것으로 보이나, 1970년대 하반기(10~12 수준)에 비하여는 크게 하락하였음을 살펴보았다. 본 연구는 이와 같은 상대적 지가하락의 주요한 한 요인으로 그동안 취해져 온 토지관련 실효세율의 상향조정을 검토하였다. 그 결과 국민소득의 10배를 상회할 정도로 크게 부풀려져 있었던 1970년대 하반기의 지가총액이 당시 토지에 대한 실효세율이 사실상 0에 가까웠다는 점에 의하여 상당 부분 설명될 수 있다는 점을 시사하고 있다.

This study examines the anchoring effect and the adjustment process of two variables(verbal information, cognition load) with snack products. In the results of this study, 1) we found the anchoring effect because the respondents predicted more the number of real units(goraebap) on the packaging painted 25 units than 5 ones. 2) We confirmed the moderating effect of verbal information. The difference of the number of real units predicted between the two packaging was decreased when the visual information was in company with verbal information. And 3) the moderating effect of cognitive load appeared because the more cognitive load was, the less the difference of the number of real units predicted was. This study has shown that we can reduce the errors and biases by adjusting the information frame or the cognitive load. This research provides a theoretical-practical implications to the marketing staffs like packaging designers as well as scholars to study consumer psychology.

수자원과 관련된 많은 분쟁 및 갈등들은 국내뿐만 아니라 전 세계적으로 발생하고 있다. 따라서 분쟁 및 갈등해결을 위한 많은 연구들이 진행되고 있지만 수자원과 관련된 분쟁들은 대부분 원활한 해결을 이루지 못하고 있으며, 특히 국내의 경우에는 더욱 심각하다 할 수 있다. 따라서 제한된 자원인 수자원을 둘러싸고 수자원분쟁이 일어나는 것은 당연한 일이라 할 수 있으며, 분쟁의 양상도 다양하다. 댐 건설로 인한 상류지역과 하류지역의 갈등, 수로의 건설로 인해 수자원을 빼앗기는 지역과 수자원을 얻게 되는 지역 간의 갈등, 새로운 공단이나 개발로 인하여 하류지역에서 수질악화를 우려하여 반대하는 경우 등 여러 종류의 수자원으로 인한 분쟁이 있다. 수자원을 둘러싼 갈등이 쉽게 해결이 되지 않고, 또한 갈등 및 분쟁이 쉽게 발생되는 이유도 주체자들간 입장 차이에서 오는 성격이라 할 수 있겠다. 수자원과 관련된 분쟁에서 오는 여러 가지 갈등들은 사회적으로 많은 문제들을 발생시켜 수자원의 원활한 공급이 저해될 수 있다. 이로 인해 사회적으로 수자원과 관련된 분쟁 해결에 들어가는 많은 시간과 노력, 비용을 생각해 볼 때, 효과적인 갈등 및 분쟁의 해결은 국가적 발전에 있어서 영향을 줄 수 있다. 그러므로 갈등 및 분쟁의 원활한 해결이 국가적 발전에 많은 비중을 차지 한다고 할 수 있다는 것은 이런 이유들 때문이라 할 수 있다. 본 연구에서는 국내 수자원과 관련된 분쟁사례들을 하천의 기능에 따른 분류, 발생 원인에 따른 분류, 분쟁주체에 따른 분류 등을 유형별로 구분하여 수자원분쟁의 여러 가지 사례들을 조사하였다. 또한 분쟁 및 갈등을 해결하기 위한 방안으로 거버넌스 시스템을 적용하였고 분쟁의 원활한 합의 조정방안 및 문제점을 제시하기 위한 외국의 시민참여 모델을 특징 및 특성을 분석하였다. 또한, 공영시각모형, 게임이론, 제도설계이론의 공학적 모형을 바탕으로 물분쟁의 해결을 위한 대안을 모색할 수 있는 과학적 접근 방안을 제시하여 향후 여러 가지형태의 국책사업 시행 시 발생 할 수 있는 분쟁의 해결 및 조정을 위한 방안으로 활용할 수 있는 토대를 마련하고자 한다.

In order to develop a convenient method for the estimation of transport distance of settling stones in quiescent water or flowing water, introduced was the simple but relatively accurate equation of drag coefficient. The equation of drag coefficient introduced was confirmed to give relatively accurate evaluation for the drag force of smooth-surface sphere, and the effects of surface roughness and shape can be considered by adjusting empirical parameters. A theoretical equation has been developed for the settling velocity or settling distance of smooth-surface sphere in quiescent fluid, and the computation results have been obtained by adjusting the empirical parameter for the settling distance of stone in quiescent water. The 2nd order ordinary differential equation has been developed for the case of settling stones in flowing fluid, and a numerical model has been developed by using Runge-Kutta method for its solution. A number of cases have been tested by adjusting the empirical parameter.

The purpose of this study is to examine the influence of variable cash compensation depending on short-term performances instead of stock compensation for the executives on the investment in tangible assets, investment and R&D, and profit reconciliation. The detailed objectives of the study include, first, to examine the influence of the cash compensation on investment in tangible assets and profit reconciliation depending on the characteristics of the company and, second, to examine the influence of cash compensation on the profit reconciliation of the investment in R&D depending on the characteristics of the company. The results of the analysis in this study can be summarized as follows; Firstly, the result of the positive analysis, as the compensation for the executives increased, by the characteristics of the companies conducted on the significant 'positive' (+) on the investment in R&D and the profits reconciliation showed that the high tech industry and the share ratio of the executives did not show a significant result, while the debt ratio showed a significantly positive result. Secondly, the result of the positive analysis, as the compensation for the executives increased, by the characteristics of the companieson the significant 'positive' (+) of the investment in tangible assets and reconciliation of profits showed that the high-tech industry did not show a significant result, while the hypothesis on the share ratio of the executives and the hypothesis on the debt ratio showed results that are significantly positive as expected. In other words, it can help Korean companies, which have to investment in R&D and tangible assets to increase their competitiveness and promote future growth dynamics, to design a manager compensation system that is appropriate for our country to support efficient investment decision-making.

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.

The relationship between R&D investment and subsequent change has been mostly confirmed under additional influencing factors, with the form of innovation investments. The research assumes that a firm adjusts its R&D spending in accordance to performance feedback. It is argued that an increased fluctuation of a firm's R&D expense is related to a reduced performance. This hypothesis is tested on SME in World class 300 Projet by SMBA. Using panel data models, instability measured by SD is related to performance levels measured by ROA, ROE & PM. Results support the proposed relationship between R&D expense instability and the subsequent performance. Although a causal link cannot be clearly established, the results indicate that firms with a lower performance have higher R&D investment fluctuations, possibly being more responsive to performance feedback.
