A number of recent studies have contributed to an increased understanding of how and why workers feel bound to their unions. However, by now there has been limited theoretical works on the various forms that union membership can take. Thus, the goal of this study is to develop the types of union membership. To develop the types of union membership, I used the ideological and instrumentalitic concepts. The types of union membership are identified as follows: Positive free agents (${\Leftrightarrow}$ Negative free agents) have low levels of both positive (negative) instrumentality and positive (negative) ideology. If positive (negative) instrumentality is high and positive (negative) ideology low, this group may be labeled Instrumentals (${\Leftrightarrow}$Disgruntled). Expressives (${\Leftrightarrow}$Antagonizers) have low levels of positive (negative) union instrumentality and high levels of positive (negative) ideology. Those who have high levels of both positive (negative) ideology and positive (negative) instrumentality have been called Identifiers (${\Leftrightarrow}$Opponents). Variables related to union instrumentality, and union ideology were investigated: (1) the personal characteristics of individual members, (2) the employing organization, (3) the union characteristics, (4) the economic environment, (5) the labor relations climate.

This paper illuminates the patterns of growth and declines in sizes of union membership in metal, chemical, financial, and auto transport sectors in three distinct periods during the last four decades from 1963 to 2003. This paper also calculates union densities in auto assembly, auto supply, and shipbuilding industries of the metal sector, cement, petroleum refining, and pharmaceutical industries of the chemical sector, private banking industry of the financial sector, and city bus industry of the auto transport sector. Such diversities in both sizes of union membership and union densities among sectors and industries turned out to be associated with attitudes and choices of employers and unions in interaction with sector- and industry-specific economic (growth stage and path), institutional (degrees of government intervention), and social (demographic features of employees and prevailing sizes of firms) environment. Such finding shows that theoretical reasonings on sizes of union membership and union densities across sectors and industries in advanced nations are also relevantly useful to analyze the Korean case.

Since World War II nations have formed alliances for reasons of security and trade. Countries have seen international integration as an appropriate approach to resolving domestic and international political issues, improving their welfare by both transforming their infrastructures and increasing their foreign trade. While the majority of these relationships are straightforward d Turkey's relationship with the European Union is more complex due to differences in religion and, at times, political ideology from other Union members. As a candidate country Turkey has made advances towards the full membership of the European Union with the customs union being the most significant. The impact of customs union membership is discussed and the effects of the customs union on Turkey's trade and economy are examined from a perspective of different economic theories.

Strategic aim of Poland is an accession to The European Union. This accession means consolidation of democratic transformations and acceleration of economical development. Possibly full and quick execution of preparing works at building domain is one of conditions of Polish membership in the European Union. Poland has to adopt rules and standards, which are required at EU. It will permit to make polish companies more attactive at international market. We should know, that economical, legal whether political reforms, this is not all what consists on membership at the Union European. We must change internally, become open to the world, to represent dynamism, enterprise, knowledge and culture. We must become more tolerant and be able to communicate with people with different culture whether political orientation, we have to accept this dissimilarity and will find way of dialogue and cooperation.

The main purpose of this study is to examine the effect of QUMR to job attitude and job performance from a industrial relations management point of view. Concretely, it is confirmed whether there are effects of QUMR to organizational commitment, turnover intention and job performance of employee and whether there is a moderating effect of union membership status between QUMR and organizational commitment, QUMR and turnover intention, QUMR and job performance of employee. As a result of this study, firstly, there is a positive effect of QUMR to organizational commitment. Secondly, QUMR effects to turnover intention negatively. Thirdly, QUMR effects to job performance positively. Lastly, there is no moderating effect according to union membership status. On the basis of these study results, I suggested alternatives of business strategy for effective industrial relations management.

In this study, the fuzzy programming is extended to handle various types of membership functions by transformation of the complicated fuzzy programming problems into the equivalent crisp linear programming problems with single objective. It is well-known that the fuzzy programming problem with linear membership functions (i.e., ramp type) can be easily transformed into a linear programming problem by introducing one dummy variable to minimize the worst unwanted deviation. However, until recently not many researches have been done to handle various general types of complicated linear membership functions which might be more realistic than ramp-or triangular-type functions. In order to handle these complicated membership functions, the goal dividing concept, which is based on the fuzzy set operation (i. e., intersection and union operations), has been prepared. The linear model obtained using the goal dividing concept is more efficient and single than the previous models [4, 8]. In addition, this result can be easily applied to any nonlinear membership functions by piecewise approximation since the membership function is continuous and monotone increasing or decreasing.

Purpose: This study was done to investigate the effects of university hospital nurses' organizational conflict between organizational commitment and labor union commitment, so as to provide data on prevention of conflict with the hospital and to improve work achievement with commitment of two different groups: hospital and labor union commitment. Methods: Data collection was conducted from May 15 to 31, 2011 for nurses registered in the labor union of a university hospital. The collected data were analyzed using t-test, ANOVA, Scheffe test and multiple regression. Results: Organizational commitment of the nurses showed significant differences according to age, position and work experience, and degree of labor union commitment according to academic achievement. The factors affecting labor union commitment were organizational conflict and recognition of need for labor union, which accounted for 19% of the variance. Factors affecting organizational commitment were organizational conflict, recognition of need for labor union, participation in organizational events, and renewal of membership in the union, which accounted for 33% of the variance. Conclusion: The results of this study indicate that there is a need to improve work achievement by minimizing conflict and preventing labor disputes for better organizational commitment and labor union commitment of nurses.

Recently, women astronomers have played increasingly important roles in the International Astronomical Union (IAU). Although only 18% are women across the entire membership of the IAU, currently one half of the IAU Executive Committee members are female. In fact, the previous, current, and next presidents of the IAU and many of the Division presidents are women. I will review a variety of efforts that the IAU has carried out to pursue equality and diversity in Astronomy. Also I will share my personal experience and thoughts on meritocracy as a guiding principle that governs academic integrity and scholarly power system in scientific communities in Korea.

In the process of simplifying the complex fate of the plant into a binary state, the information loss is inevitable. To minimize the information loss, the quantification of plant safety status has been formulated through the combination of the probability density function arising from the sensor measurement and the membership function representing the expectation of the state of the system. Therefore, in this context, the safety index is introduced in an attempt to quantify the plant status from the perspective of safety. The combination of probability density function and membership function is achieved through the integration of the fuzzy intersection of the two functions, and it often is not a simple task to integrate the fuzzy intersection due to the complexity that is the result of the fuzzy intersection. Therefore, a methodology based on the Algebra of Logic is used to express the fuzzy intersection and the fuzzy union of the arbitrary functions analytically. These exact analytical expressions are then numerically integrated by the application of Monte Carlo method. The benchmark tests for rectangular area and both fuzzy intersection and union of two normal distribution functions have been performed. Lastly, the safety index was determined for the Core Reactivity Control of Yonggwang 3&4 using the presented methodology.
