During the whole product design and development processes, the concurrent engineering relies on strong and permanent interactions between the departmental functions. Concurrent or simultaneous engineering in new product development is a new concept which needs to be redefined. This paper deals with a concurrent engineering model which represents how concurrency, as an organizational process, is related to a interfunctional project team. Four dimensions shaping the sucess of the concurrent engineering are suggested with detailed meausrement instruments. Moreover, an empirical study on the effects of the four dimensions on the efficiency of the product development processes is carried out in the field of electronic industries.

In 1990's, in Europe and some advanced nations, the structural reform of the railroad industry for improving the productive efficiency of the railroad industry and competitive power had been progressed. This paper empirically explores the relationship between railway restructuring and productive efficiency in the railway industry. We use Data Envelopment Analysis (DEA) to construct efficiency scores, and explain these scores, using Tobit regression analysis by using variables reflecting institutional factors and organizational type. Our results suggest that vertical separation, infrastructure and services are separated, and horizontal separation, passenger service and freight service are separated, improve productive efficiency. We also find that market competition has positive effect on the efficiency, but independent management from the government has negative effect, which is in line with economic intuition as well as with expectations on the railway restructuring. As a consequence, increased independence without sufficient competition and adequate regulation may deteriorate incentives for productive efficiency.

적절한 벤치마킹 대상의 선정은 조직 계획 및 통제에 있어 중요한 요소로 인식되고 있으며, 이에 대한 많은 연구가 이루어져 왔다. 특히, 조직의 상대적 성과 평가와 이를 바탕으로 벤치마킹 대상을 결정하는 DEA(data envelopment analysis)의 출현은 벤치마킹에 대한 연구를 증대시켜왔다. 하지만, 벤치마킹 대상 선정은 기술적 생산 가능성 측면 외에도 조직의 정책적 고려, 관리적 우위 그리고 외부 제약 등을 고려해야 한다. 따라서 수리적 결과에 바탕을 둔 기술적 생산 가능성만을 가지고 벤치마킹 대상을 제공하는 현재의 DEA 접근 방법에는 한계가 있다. 즉, 고려하는 모든 대상을 기반으로 한 global efficiency 관점에서 제공하는 해가 비 효율적 조직 입장에서는 바람직하지 않을 수도 있다. 이에 따라 본 연구에서는 local efficiency 개념을 도입하여, 다양한 관점에서 벤치마킹 대안들을 살펴 볼 수 있는 방법을 제공하고자 한다. 이는 다음과 같은 과정에 의해 수행된다. 먼저, DEA를 이용하여 비교하고자 하는 모든 DMU(decision making unit)의 투입/산출물을 바탕으로 각 DMU의 효율성 값과 비효율적 DMU의 참조집합 (reference set)을 도출한다. 다음으로, 도출된 참조집합이 조직 운영 관점에서 적절한 벤치마킹 대상이며, 이러한 목표를 달성할 수 있는가를 평가한다. 이때 도출된 벤치마킹 대상이 적절하다면 분석과정을 종료하고, 적절하지 않을 경우 다음과 같은 추가적인 분석을 수행한다. 우선, 각 참조 집합을 중심으로 DMU를 그룹핑하고, 각 그룹별로 효율성 값 및 참조집합을 도출한다. 이때 도출된 효율성 값이 local efficiency 값에 해당된다. 다음으로, 참조 집합 그룹을 중심으로 도출된 비효율적 DMU의 참조집합이 적절한 벤치마킹 대상인가를 판단한다. 적절한 벤치마킹 대상을 도출하였으면 분석을 종료하고, 그렇지 않을 경우 적절한 벤치마킹 대상을 도출할 때까지 추가적인 분석과정을 반복한다. 제안한 방법을 통하여 조직은 기술적 생산 가능성 외에도 다양한 조직 운영 관점에서 적절한 벤치마킹 대상을 선정할 수 있으며, 이에 따른 목표를 수립할 수 있을 것으로 기대한다. 또한 더 나아가 global efficiency 관점에서 효율적 조직이 되기 위하여 단계적인 벤치마킹 대상 선정과 이에 따른 목표를 수립하는데도 유용하리라 판단된다.

DEA(Data Envelopment Analysis) is useful to measure the relative efficiency of organizational units where the presence of multiple inputs and outputs. This study applied DEA-CCR and DEA-BCC to evaluate the technical, pure technical, and scale efficiency of 29 university libraries. The input variables were number of books, print edition expenses, building space, staff, number of seats. As output variables we estimated: reader visits, number of borrowed items, number of visitors. It was found out that number of libraries with 100% relative efficiency among 29 libraries were 13. Also the results shows that main reason of inefficiency was from scale rather than from pure technical. Many inefficient libraries were operations of increasing return to scale.

Existing research indicates that job design influences not only a worker's psychological well-being but also the individual and organizational performance. This study has been motivated by the need to provide useful implications for increasing the efficiency of business operations. The purpose of this research is to investigate the relationships between job characteristics and performance factors in the domestic financial industry. The conceptual framework has been developed based on Hackman & Oldham's job characteristics model and the related literature. We conducted a survey of employees in the domestic financial firms to test the conceptual model and hypotheses, and analyzed the data using the structured equation modeling method. The results of the empirical analysis indicate that the variety and autonomy of a job positively affect corporate innovation, confidence, and job satisfaction and that corporate innovation and job satisfaction positively influence job commitment. This research designed to examine the relationship between job characteristics and organizational performance will make a contribution to the improvement of business efficiency in our society.

Purpose - Since the early 1990s, it has been observed that the number and substance of studies on female leadership have been increasing. One of the reasons for this development may be concerned with the increasing number of female labor market participants as well as the greater opportunities for them to take higher positions in various organizations. In addition to this, the transition from mechanistic organizational structures that emphasize authority, control, and efficiency toward organic ones that focus on environmental adaptability, equality, and trust has also encouraged research on female leadership. The research tendency is based on the assumption that male and female leaders tend to exhibit different leadership styles according to their gender differences. Recent research has cast doubt on this assumption, by showing that the sociological gender roles of men and women are independent such that some female leaders show authoritative and control-oriented leadership, which were once considered to be male leadership styles. Research design, data, and methodology - This research attempts to carry out an empirical study on the gender-related leadership styles of female leaders and to examine their effect on group performance in the K business organization. This study also focuses on leader attributes such as trust, and it aims to discover whether these attributes should be regarded as independent or as moderating variables between leadership styles and performance. For these purposes, this study generated four hypotheses based on a review of the literature and it tested them using a survey. Female workers in the sales departments of the K Company, all of whom are women, were asked to provide answers to the presented questionnaires. This study hypothesizes that the type of gender roles played by women leaders will affect the job satisfaction and organizational commitment among the members of the sales group, and that the level of trust that is garnered by women leaders will also affect the types of gender roles that they play as well as employee job satisfaction and organizational commitment. Results - The results of this study show that both androgynous and masculine leadership styles are superior to the feminine leadership style in terms of employee job satisfaction and organizational commitment. However, contrary to our expectations, this study fails to show the superiority of the androgynous leadership style over the masculine leadership style. Moreover, there are no significant differences between these two leadership styles with regard to group performance. Conclusions - This study shows that it is important that different attributes of leaders, such as how trusted they are, be treated as moderating variables between leadership and performance rather than as independent variables. Finally, as this is the first attempt to view the role of the gender in a new perspective, the managerial implications of this study for leadership research, as well as its limitations, are presented. Suggestions for future related research are also proposed.

The purpose of the study was to identify and compare levels of recognition of empowerment, job satisfaction, organizational commitment between Advanced Practice Nurses(APN) and Registered Nurses(RN) of hospitals. Data collection was done by the 85 APN and 120 RN of six large hospitals, four medium sized hospitals in Seoul and Incheon. T-test and ANOVA using SPSS 18.0 were performed. There were no significant differences of empowerment between APN($3.56{\pm}0.53$) and RN($3.50{\pm}0.54$)(t =-. 861, p = 0.390). job satisfaction between APN($3.36{\pm}0.53$) and RN($3.25{\pm}0.46$)(t =- 1.575, p = 0.117), organizational commitment between APN($3.11{\pm}0.34$) and RN($3.05{\pm}0.36$)(t =- 1.301, p = 0.195). Empowerment, job satisfaction, organizational commitment of APN and RN showed no significant differences. There are some reasons why it resulted in no significant difference between APN and RN. APN's role in Korea is not clearly established and distinguished from RN, lack of appropriacy of employment and reward, and lack of the institutional foundation for APN's operation and efficiency.

Although the demand for the use of public data increases in accordance with the expansion of Government 3.0, the poor level of data quality and its management currently implemented is becoming obstacles to opening data to the public. To improve the efficiency of management, linkage and usage for data, standardized processes for data quality management have to be prepared and appropriate data quality assessment criteria should be established. In this paper, we propose the organizational maturity model that can assess the public data quality management level. This model consists of the process reference model and the measurement framework. Fifteen processes grouped by the PDCA cycle are defined in the process reference model. The measurement framework measures the organizational maturity level based on process capability levels. The organizational maturity model can be used to establish objectives and directions for public data quality improvement by diagnosis of current level of public data quality management and problem solving. This model can also facilitate open to the private sector and activate usage of stable public data through reliability enhancement.
