건설진도율은 프로젝트 성과 측정 및 진행관리의 중요한 요소 중의 하나로서 이용되고 있으나, 작업 진도 산출기준 및 방법이 현장 상황에 따라 다르게 운영되기 때문에 진도 산출의 정확성이 각 현장 특성에 크게 의존되고 있는 실정이다. 즉, 현장별 공사 진행 상태 비교 시 상당한 오류-가 발생될 수 있으며, 그 신뢰도 역시 매우 떨어질 수 있다는 것을 의미한다 따라서 본 연구에서는 모든 현장의 공사 진행 상태를 같은 기준으로 파악이 가능한 전사 차원으로서의 공통 기준인 진도관리단위 및 평가요소를 정의하며, 이와 더불어 진도관리단위 적정성 평가 방안 및 진도산정모델의 프로세스를 제안하고자 한다.

The objectives of this study were to 1) classify the cooperative farmers' organizations in Korea according to the development level and institutional aspects through the exploration of its' conceptual and institutional basis, 2) analyze the farmers' needs for organization, 3) identify the problems and situation of organizations, and 4) formulate an effective management model for each cooperative farmers' organization. The study was carried out through a review of literature and using available statistical data collected from various sources and empirical survey. Major findings of the study were: 1) the cooperative farmers' organizations could be classified into four types : crop units, farming cooperative corporation, trust farming companies and joint-stock agri-business. 2) a lot of members of the organization feel that the information is insufficient, the opportunity to suggest their own ideas is hardly given, and the members are not satisfied with the cooperation among the members, 3) the members who have higher level of schooling education showed a higher participation level in the organization, 4) most of members did not recognize the organization they participated in, 5) participation of the organization's members and concerned institutions is an important factor to promote problem solving and better communication within the organization, 6) any type of continuing education for the members is needed to facilitate the transfer of a new agricultural and organizational technology, 7) research and development(R & D) is one of the most important factors of the development of organizations, 8) most organizations are deficient in professional management skills(financial, personal, accounts, etc.), 9) the trust farming companies have difficulties in managing the firm on account of the characteristics of agriculture(especially seasonal), the dispersed trust lands, and the need for more alternative work in the winter season, and 10) in the case of agri-businesses, their organizations are more specialized in marketing and have more structured systems of management. Based on the results of the study the following recommendations were made for further improvement and development of agricultural cooperative organizations : (1) More governmental support should be given to education for improvement of the organizational structure. And more deliberate and differentiated governmental support should be provided for the organizations to be viably managed. (2) For more efficient communication between the members and the organization, more opportunities for discussion are needed. (3) The more research should be committed to this kind of work in order to get more analytic data and strategic plans of cooperative organizations.

The intention of this study was: 1) to standardize the Korean version of the Dogmatism Scale, 2) to examine whether environmental structure affects value systems such as attitudes toward work, time perspective and the personality dimension of dogmatism in adolescent vocational and non-vocational trainees, 3) to examine relationships between those value systems and group differences in personality characteristics of vocational and non-vocational trainees, 4) to observe whether there are differences between high-dogmatism and low-dogmatism subjects with regard to attitudes toward work and future time perspective. The subjects for the study included 841 adolescent vocational (226) and nonvocational (615) from vocational training centers, schools and universities in Seoul. The instruments used in this study were 1) a questionnaire for attitudes toward work, 2) the Future Time Perspective (FTP) developed by Christiansen and 3) the Dogmatism Scale. The results of the present study indicated that behavior settings or environmental variables such as organization type affect the formation of attitudes and of dogmatism in adolescents. The results also showed that dogmatism relates to future time perspectives. This differs from Rokeach's theoretical statements. Dogmatism in this study was related to time perspective, the relationships were optimistic in emotional areas, long-term in direction and concrete in structure. The inconsistency between the results of the present study and Rokeach's suggests further study. A "Psycho-Environmental Model" for the formation of value systems based on the results of this and earlier research of the author were discussed.

The fine structural characteristics of cardiac muscle cells and its myofibril organization in the orb web spider N. clavata were examined by transmission electron microscopy. Although myofibril striations are not remarkable as those of skeletal muscles, muscle fibers contain multiple myofibrils, abundant mitochondria, extensive sarcoplasmic reticulum and transverse tubules (T-tubules). Myofibrils are divided into distinct sarcomeres defined by Z-lines with average length of 2.0 ㎛, but the distinction between the A-band and the I-bands is not clear due to uniform striations over the length of the sarcomeres. Dyadic junction which consisted of a single T-tubule paired with a terminal cisterna of the sarcoplasmic reticulum is found mainly at the A-I level of sarcomere. Each cell is arranged to form multiple connections with neighboring cells through the intercalated discs. These specialized junctions include three types of intercellular junctions: gap junctions, fascia adherens and desmosomes for heart function. Our transmission electron microscopy (TEM) observations clearly show that spider's cardiac muscle contraction is controlled by neurogenic rather than myogenic mechanism since each cardiac muscle fiber is innervated by a branch of motor neuron through neuromuscular junctions.

This study focused on the one and only temple of on the coastline of the West Sea, Kimje's Manghae Temple and Mt. Jinbong. The purpose of this study was to research the unique sense of place of the area by researching the location and view that clearly shapes the identity of the landscape. The following are the results. 1. The cultural landscape of Manghae Temple and the natural landscape of Mt. Jinbong have characteristics which take in the coastline and skyline, respectively. Specifically, from the existential vertical-horizontal images of "sky - land - Mt. Jinbong" and "moon - cloud - sea", an ascending reflection of the landscape surroundings can be found. 2. The "Sea - Manghae temple - Mt. Jinbong - sky" is the representation of the moderate 'inside-space' which belongs to the particular landscape area and which also shows the topophilia to Manghae Temple. Through this kind of interpretation, the sense of place of Manghae Temple and Mt. Jinbong reveals an intra-structure of an Imaging Landscape implying harmony and moderation, which is a unified organization of the surrounding phenomena(Temple and Mountain) and the essence (the doctrine of Buddhism) that matches Jin-muk's asceticism and lifestyle. 3. While the cultural landscape of Manghae Temple has a strong religious reference, the natural landscape Mt. Jinbong emphasizes the geography of the landscape. In other words, the motivating factor of Manghae Temple is a metaphorical sense of place such as through the "prospect of the sea" or "the Western Sea Paradise" and Mt. Jinbong, the landmark of the Kimje-Mankyung Plains and the focal point of the West Sea sunset, is highlighted as a simile for this sense of place. 4. Keeping this sense of place and territory respectively and showing the. bond with the sense of place which develops rhythmically and continuously, Manghae Temple and Mt. Jinbong are sublimated into a unified intra-structure, which reflects the Imaging landscape characteristics of "Mt. Jinbong, a focal point of the Mankyung Plains facing the West Sea" and "Manghae Temple, looking out to sea".

The main objective of this study is to examine the government ownership effect on the United Arab Emirates (UAE) firm's corporate social responsibility (CSR). Government ownership is assumed to affect the CSR either directly or indirectly. That is by moderating the association between corporate governance and CSR. Publicly listed companies on the UAE capital markets (Abu Dhabi and Dubai) from 2010-2013 constituted the study sample. Panel data regression analyses and random effect model is used to examine the effects of board size, board independence, and audit committee characteristics on CSR. Government ownership is used as a moderator variable. The result showed that the existence of government ownership has a moderator effect on the association between corporate governance mechanisms and the CSR. Precisely, the research revealed that the audit committee characteristics become more effective in improving the firm's CSR when the government owns shares in the organization. The main contribution of this study is to examine how firm ownership structure influences good corporate governance and CSR in the UAE. The study contributes to the CSR literature by merging between the existence of governmental ownership and the power to enforce the implementation of corporate governance in an emerging country.

The ISO(International Standard Organization) has standardized MPEG-2 audio. The MPEG-2 audio compression algorithm is based upon subband analysis and exploits the human auditory characteristics to achieve a low bit rate with minimum perceptual loss of audio signal quality. This thesis presents an enhanced MPEG-2 audio encoder using multiple TMS320C30 general purpose DSP's. The developed system is made up of five slave boards and one master board. Each slave board performs susband analysis psychoacoustic parameter calculation for one channel, and the master board manages bit allocation, quantization, and bit-stream formatting for all channels. Parallel processing and pipelining techniques are used in hardware structure and fast algorithms are applied in each subroutine to implement a real-time process. The implemented system supports multichannel up to 5.1 and various bitrates.

As a way to raise the brand value of each area and activate local industries, public design projects have been competitively made. Meanwhile, public design has the characteristics of having an uncertain number of users, people with different interests, and management of the design by an administrative organization. Such characteristics may be obstacles to the results of public design and finally can cause many problems in a project's results. However, although most local governments have executed public design projects, systematic research for them and organized execution of the projects has been insufficient. For successful realization, proper organization, and consistent public design, research on a strategic design process is needed. Therefore, this study investigated the current status of public design projects to understand problems in the design process and solve them. The results are presented as follows: First, the design process for public spaces has a dual structure including a specialized process of design development in its execution and management and the execution process in the planning state is unsatisfactory and the process of designer selection is not consistent. Second, as a result of investigating the current status of the design process for public spaces, it was deduced that as most of the projects have been subjectively and temporarily managed by wholly charged organizations without specialized consultation or investigation with different related departments, there have been diverse problems in securing design quality. Third, as a result of analysing the specific execution processes carefully, it was suggested that problems in the process can be solved by decisions through consultation and discussion. As well supportive consultation systems should be used actively.
