저자는 이 책에서 사진의 기교적 예술적 측면에 대해 다루기 보다는 사진술을 미학적 과학적 그리고 정치적 현상으로 파악하고 있다. 저자는 사진술 속에서 20세기 말 우리 문화가 당면하고 있는 근본적인 위기를 성찰하면서 그 원인과 해결책을 포괄적으로 분석하는 개념을 발전시키고 있다. 이를 위해 저자는 사진과 관련된 제 현상들, 프로그래밍된 자동 사진기의 작동원리, 사진의 생산과 배포 과정 등을 철학적 정신에 입각해서 분석, 사진을 현재 유행하는 디지털 미디어의 고전적$\cdot$선구적 형태로 파악함으로써 ,사진의 역사로부터 오늘날 디지털 혁명의 뿌리를 캐고 있다.

The basic objective of broadcast scheduling is to get the smallest length TDMA frame, where many nodes are allowed to transmit simultaneously in a single time slot in a conflict-free manner. The secondary objective is to maximize the number of such transmissions for maximum use of the channel. An Artificial Bee Colony (ABC) with ranking strategy is proposed in this paper for the broadcast scheduling problem. Our proposed method is very efficient for generating initial and neighbor feasible solutions. We can get the best number of time slots and transmission utilization comparing to previous researches.

This paper analyze the fee structures of digital music contents and the revenue sharing ratios that are now on-going debates in Korean digital contents industry. Especially we consider Korean situation where copyrighters and telecom companies have conflict of interest. We found two major results. First, the choice between the flat rate scheme and the usage-based rate scheme is not important to telecom companies and copyrighters. The important thing is that copyrighters should decide the revenue sharing ratio and given that telecom companies should decide the retail price. Consequently, this way can lead to win-win solutions between them. Second, the flat rate scheme affects the relationship between consumers and telecom companies. Under the flat rate scheme, telecom companies have more benefits than consumers. In the vertical integrated structure, particularly, this tendency is more severe.

Designers are frequently faced with multiple quality issues in injection molded parts. These issues are usually In conflict with each other, and thus tradeoff needs to be made to reach a final compromised solutions. The objective of this study is to develop an automated injection molding design methodology, whereby part defects such as warpage and weld line are optimized. The features of the proposed methodology are as follows: first, Utility Function approach is applied to transform the original multiple objective problem into single objective problem. Second is an implementation of a direct search-based Injection molding optimization procedure with automated consideration of process variation. The Space Reduction Method based on Taguchi's DOE(Design Of Experiment) is used as a general optimization tool in this study. The computational experimental verification of the methodology was partially carried out for a can model of Cavallero Plastics Incorporation, U. S. A. Applied to production, this study will be of immense value to companies in reducing the product development time and enhancing the product quality.

This paper describes the development of new feature positioning method which embedded into the top-down assembly modeling system supporting conceptual design. In this work, the user provides the geometric constraints representing the position and size of features, then the system calculates their proper solution. The use of geometric constraints which are easy to understand intuitively enables the user to represent his design intents about geometric shapes, and enables the system to propagate the changes automatically when some editing occurs. To find the proper solution of given constraints, the Selective Solving Method in which the redundant or conflict equations are detected and discarded is devised. The validity of feature shapes satisfying the constraints can be maintained by this technique, and under or over constrained user-defined constraints can also be estimated. The problems such as getting the initial guess, controlling the multiple solutions, and dealing with objects of rotational symmetry are also resolved. Through this work, the feature based modeling system can support more general and convenient modeling method, and keeps the model being valid during modifying models.

This study analyzes patenting practices in the pharmaceutical industry and the impacts of sequential innovation. The main argument of the research is that strategic patenting is common in the pharmaceutical sector and it is legal within the context of patent law. However, when these practices have negative effects on the competition process post-grant, the practices that are legal under patent law may come into conflict with antitrust laws, which are not applied. The study brings into question whether sequential patenting practices characteristic of the pharmaceutical industry encourage or discourage innovation, and moreover, the overall functionality of the patent system. Ultimately, the functionality of the patent system creates market incentives that neglect consumer, i.e., patient, welfare; potential solutions to deal with the shortcomings are discussed.

This study applicates one of the five elaborated functional analyses of Piotr Stztompka to the housewives’study. The four general assumptions of plurality, wholeness, integration and boundary of the simple system issue the eight specific solutions; reciprocity, exploitation, consensus, conflict, dependence, autonomy, isolation and structural context of the relationships among the various elements of the system. From the eight specific assumptions of the housewives’studies, we have found that many managerial subsystem studies see the housewives’relationships to other elements in their reciprocity, concensus, dependence and isolation characteristics. If the assumptions of autonomy and structual context are used to this kind of study, we can understand the housewives’problem and potential but as an active subject of their humanlives, not as a simply passive primary manager of the family, and we can find a new concept of the development to change the housewives’quality of life.

Recently companies have increased the new projects to improve and innovate the business process in order to adopt the advanced technologies such as IoT (Internet of Things), Big Data Analysis, Cloud Computing, mobile and artificial intelligence technologies for sustainable competitive advantages under rapid technological and socioeconomic external environmental changes. However, there are obstacles to achieve the project goals, corporate's strategy and objectives due to various kind of risks based on characteristics of projects and conflicts of stakeholders participated on projects. Hence, the solutions are required to resolve the various kind of risks and conflicts of stakeholders. The objectives of this study are to investigate the impact of the project governance, agency conflicts on the project success based on agency theory by using the statistical hypothesis testing the relationship among those variables. As a result of hypothesis testing, we could find that the project governance impacts positively on project success and negatively on the agency conflicts. Further, the agency conflicts impacts negatively on the project success. Finally, we could find that the agency conflicts such as goal conflict, different risk attitude and information asymmetry between project manager and team members impact negatively on the project success. Meanwhile, the project governance impact positively on the project success, negatively impact on the agency conflicts such as goal conflict, different risk attitude and information asymmetry between project manager and project team members. In order to increase the project success rate, the project governance institutions such as PGB (Project Governance Board), EPMO (Enterprise Project Management Office), PSC (Project Steering Committee) are needed to prevent or reduce the agency conflicts between project manager and team members.

본 연구는 간호사와 간호조무사의 동기를 제고하고 효과적인 간호서비스 제공을 촉진하기 위해 의사와의 관계에서 간호사와 간호조무사가 느끼는 직무 및 대인관계의 갈등 정도와 원인을 파악하고자 수행하였다. 이를 위해 중소규모 병원에 근무하고 있는 간호사와 간호조무사 271명을 대상으로 직무 및 인간관계 갈등 정도, 원활한 의사소통 여부, 갈등 원인과 해결방법 등에 대해 설문조사를 실시하고 분석하였다. 분석 결과 의사와의 관계에서 간호사와 간호조무사가 느끼는 갈등의 내용과 정도는 대체로 비슷하였으나 의사와 간호직의 역할이 중복되거나 모호한 부분이 있다고 느낀다는 점에서는 간호사가 간호조무사 보다 더 많은 스트레스를 받고 있었다. 의사와 갈등이 발생했을 때 해결하는 방법으로는 간호사와 간호조무사 모두 적당히 피한다는 의견이 가장 많았다. 그 다음의 갈등해결 방법은 간호사와 간호조무사 간에 차이가 있었는데 간호사는 상대방에게 나의 의견을 따르도록 함, 노조를 통해 해결 등의 순이었고, 간호조무사는 상사에게 해결하도록 함, 서로 조금씩 양보해서 타협함 등의 순이었다.
