This article dealt with the formation and dissolution of tautological structure in the Frank Stella's work from 1959 to 1980 years by the analysis of signifier. A characteristic of Stella's work change is that it has the gradual progress which condensed into three periods -1) the formation and fixation period of tautological structure 2) the relaxation period of tautological structure and 3) the dissolution period of tautological structure. In other words, the early works of stella in the early 1960s has the structure which minimize differences in one hand, and maximize strictness, clearness, and identity on the other hand However, the stella's work from mid 1960s to mid 1970s extend differences gradually, while keeping a characteristic of prior work. And the stella's work after late 1970s has the decentered disintegration, namely anti-tautological structure which maximize differences. 'The formation and dissolution of tautological structure' in the Stella's work could be understood in relation to the fact that the Greenberg's modernist canon has loss the power gradually after late 1960s. That is to say, the dissolution of tautological structure in the late stella's work could be interpreted as the inevitable product which is produced in the searching for a new canon of painting. However, on the other hand, the structural change of stella's work in the late 20th Century is also understood in relation to the broader context, the social, and cultural context. Here, it is interpreted as the one of typical example which reflect a social and cultural convulsion designated as a 'Coming of Postmodernism'. In short, the late Stella's work which emphasize differences and unclearness, while diverging from early Stella's work which stress identity and rationality could be interpreted that it has the homology with the change of ways of thinking in the late 20th century Society.

The aim of the present study is to research into the household work time change and its structure in urban home makers by the choosen eleven studies and KBS's Data 1981, 1983, 1985, 1987. This study were proceeded under some limitations, it is choosen eleven studies that is different region: large city, medium and small town, and the household work's categories of original auther were changed. And KBS's Data was composed of general formation without personal character of home maker: FLC, number of childeren, family type, education, region. Although this study have a certain meaning of implementation, research into the household work time change and its's structure. The major findings of this study can be autlined as follows: (1) Total household work time did'nt so much changed through the choosen eleven studies compared with the last twenty years ago. In the change of each province household work time, time connected with meals and dwelling did not showed consistancy of change. But cloth laundering and mending time of 80's were declined compared with 70's. Family care time of 80's was increased, home management and buying time was declined untill '85, but again increasing trend '87. In choosen eleven studies, the household work time structure of urban home makers can be outlined: time connected with Meals>Family care>Cloth laundering and mending>Dwelling>Home management and Buying. (2) KBS's time-series data were analized as follows: a) Total household work time of '87 was declining gradually in weekday (34 minutes), sat. (41 minutes), sun (1 house and 2 minutes) compared with '81. b) The change of each province household work time: the time of cooking and sewing home management were declining gradually in its Mean time and its ratio of acters. The acter ratio of household worker in '81, '83, '85 was composed Cooking > Cleaning > Laundering > Home management > Buying > Child care > Sewing. In '87 was composed Cooking > Cleaning > Laundering > Buying > Home management > Child care > Sewing. c) The structure of household work time revealed some differences in each year and a day of the week.

The Work Breakdown Structure (WBS) is a primary tool which provides a framework that defines clear scope of all deliverables throughout the project life cycle. Once the WBS is established in projects, it should allow project team members to measure and manage work performances by the WBS; further, it should provide a reference point when any work scope needs to be redefined. Based on the project information in the Progress and Performance Measurement System (PPMS) of UAE's Barakha Nuclear Power Plant (BNPP) projects, an attempt was made to develop a new WBS which provides hierarchical and systematical decomposition of the total work scope of NPP construction projects while avoiding from the preexistence concept in Korean NPP projects that the WBS is a combination of Physical Breakdown Structure (PBS) and Functional Breakdown Structure (FBS). The unique features of the new WBS are as follows: (1) defined the definition of each level of the WBS, (2) subdivided the WBS into 5 hierarchical levels, and (3) adopted globally used general coding structure. The new WBS provides a basic hierarchical structure for the project scope and can be used as a basic tool for schedule control, performance measurement, project status monitoring, and communication among project participants. In addition, by putting the Work Package (WP) under the WBS, the Earned Value Management System (EVMS) per WP can be utilized for the project.

As a work analysis technique, Work Domain Analysis (WDA) aims to identify the design knowledge structure of a work domain that human operators interact with through human-system interfaces. Abstraction hierarchy (AH) is a multi-level, hierarchical knowledge representation framework for modeling the functional structure of any kinds of systems. Thus, WDA based on AH aims to identify the functional knowledge structure of a work domain. AH has been used in a range of work domains and problems to model their functional knowledge structure and has proven its generality and usefulness. However, many of researchers and system designers have reported that it is never easy to understand the concepts underlying AH and use it effectively for WDA. This would be because WDA is a form of work analysis that is different from other types of work analysis techniques such as task analysis and AH has several unique characteristics that are differentiated from other types of function analysis techniques used in systems engineering. With this issue in mind, this paper introduces the concepts of WDA based on AH and offers a comprehensive list of references. Next, this paper proposes a set of principles for effectively applying AH for work domain analysis, which are developed based on the author's experiences, consultation with experts, and literature reviews.

Purpose: This study was conducted to compare the characteristics of organizational structure and occupational satisfaction among nurses in general hospital and small to medium-sized hospital and to investigate the affecting factors on their occupational satisfaction. Methods: The study was based on the cross-sectional descriptive survey. A self-report questionnaire was used to collect data from 343 nurses between June and July, 2010. Data were analyzed by ${\chi}^2$-test, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and multiple regression using the SPSS/WIN 14.0 program. Results: Hierarchical structure was dominant in general hospital whereas relationship was highly valued in small to medium-sized hospital. Occupational satisfaction was positively correlated with work environment built on relationship, innovation and tasks. Factors significantly influencing on occupational satisfaction in general hospital included innovative work environment, nurses' income and their health status ($R^2$=40.3%). For the small to medium-sized hospital, they included innovative work environment, satisfaction in life, tasks and professionalism ($R^2$=40.4%). Conclusion: Organizational structure, especially innovative work environment and relationship-oriented attitude had a significant influence on nurses' occupational satisfaction. Therefore, nursing administrators have to develop and consider organizational structure to improve occupational satisfaction.

We investigated the effect of Ar ion sputtering on the surface electronic structure of indium tin oxide (ITO) using X-ray and ultraviolet photoelectron spectroscopy (XPS and UPS) measurements with increasing Ar ion sputtering time. XPS measurements revealed that surface contamination on ITO was rapidly removed by Ar ion sputtering for 10 s. UPS measurements showed that the work function of ITO increased by 0.2 eV after Ar ion sputtering for 10 s. This increase in work function was attributed to the removal of surface contamination, which formed a positive interface dipole relative to the ITO substrate. However, further Ar ion sputtering did not change the work function of ITO although the surface stoichiometry of ITO did change. Therefore, removing the surface contamination is critical for increasing the work function of ITO, and Ar ion sputtering for a short time (about 10 s) can efficiently remove surface contamination.

The purpose of this study is both to describe and to explain the shapes and the changes of Kwangju women's productive activities from the middle of 1950's to the end of 1990's. Productive activities in this study include wage labors as well as economic activities in informal labor sector and domestic labor. Three factors - economic structure, the family, and women's consciousness - are drawn to explain women's work in Kwangju. The period from the middle of 1950's to the end of 1990's has been divided into 5 stages and the characteristics of women's work at each stage are as follows : Kwangju women during 1950's worked hard and contributed to the family economy not only inside but also outside the family : during the second stage from 1960's to 1970's, they accomplished not only the traditional women's role but also industrial wage worker : the third period of the first half of 1980's was the time for the development of social consciousness : the fourth period from the end of 1980's to the beginning of 1990's was the time when women tried to solve their problems by themselves: during the last period from the middle of 1990's to the end of 1990's. Kwangiu women wanted to establish their identities in the independent area from their families.

This study examines the restoration project of Sokkuram, and introduces its preliminary plans by the architect Pai Ki Hyung. The restoration project started in 1958 with an inquiry committee of the restoration project, and was completed in 1964. Despite having undergone extensive repair work under Japanese supervision from 1913 and 1923, the repair work caused water leakages inside Sokkuram, and regular cleaning work that began in 1933 caused a lot of damage to the sculpture. In result of the surveys, the top priority of this project was to protect the sculptures inside Sokkuram by improving the environment of the cave. At that time, the architect Mr. Pai participated as a head of the fourth field surveyors to plan the restoration project and to design the preliminary plans. He proposed the installation of a double dome structure to prevent further water leakages on the concrete addition that was built up around the grotto by the Japanese. However, in 1961, the Cultural Heritage Committee of Korea examined the plans of Mr. Pai and immediately rejected them. The factors of the rejection were the omitting of entrance design, system of new double dome structure that presses the existing structure, and these changes that had to be made outside of the drainage plans. The repair work of Sokkuram began in 1961, and the main construction was building double dome structure and entrance installation. In this we realize that Mr. Pai's double dome structure plans were very important key concept of this project. This study attempts to demonstrate the double dome installations that Mr. Pai initially proposed, which ultimately remains as emblematic factors of Sokkuram's legacy.
