This article discusses the issues of the estimated size and characteristics of irregular employment work force in Korea after IMF economic crisis in 1997. The issues of the estimated size of irregular employment work force originated from different concepts and its operationalizations among the labor economists, despite their utilization of the same labor force data, 'Economically Active Population Survey(EAPA)' collected from Korea National Statistical Office(KNSO). And the issues contribute toward the understandings of the irregular employment and the limits of the EAPA, despite its various usefulness. This article also describes the summary characteristics of irregular employment work force from both sides of labor supply and its demand. The major characteristics of irregular employment work force on the labor supply side appears in the concentration of social minorities, i.e. woman, the aged, lower educated and skilled populations. On the labor demand of irregular employment work force, the majority of it concentrated on the establishments under 10 employees, and probably the important incentives for irregular employment work force of the firms is labor cost efficiency. Finally, this article propose an alternative against the discrimination between the regular and irregular work force.

In this study, we investigated web contents accessibility of 60 hospital web sites in Korea. The eight evaluation criteria were used for estimating the web contents accessibility of the web sites. These criteria were as follows: providing an alternative text, providing caption for moving picture, providing a skip navigation, usage of pop-up windows, usage of a summary or a caption tag for data table, providing a page title, providing a label for online form, and usage of java scripts. K-WAH 3.0 was used for estimating five evaluation criteria. According to Internet web contents accessibility guideline 1.0, we estimated the rest three evaluation criteria manually and described good or bad examples for the evaluation results technically. The results show that the web accessibility of hospital web sites is generally insufficient and the constant interests in improvement for accessibility are urgently needed.

This research has classified waiting times into the three different ones according to service offering process and investigated the antecedents and consequences of types of waiting times. A service provider's concern and customer involvement were modeled as antecedent variables and negative emotion and service value as dependent variables. The empirical results of the study are as follows. A service provider's concern had significant influences on all the three types of waiting times whereas customer involvement was found to affect preprocess-waiting and postprocess-waiting times. Preprocess-waiting time had a significant impact on both negative emotion and service value and inprocess-waiting time only affects negative emotion. However, postprocess-waiting time had influenced none of the variables. The findings illustrate an important role of concern and involvement regarding to a customer's perceived waiting time and relative importance of waiting types on negative emotion and service value. A summary of the results are reported and managerial implications are discussed.

The purpose of this study is to highlight the effects of the two leadership styles, namely: transformational leadership and transactional leadership, on the different types of followership through analyzing their impact in the productivity and competitiveness of human resources in IT SMEs. The paper focuses on determining whether transformational leadership or transactional leadership is more effective as shown by the levels of empowerment derived from these two types of leadership under study. From this study, alien, role model and passive types of followership, transformational leadership appears to be more influential for personal empowerment. As for group level of empowerment, the transformational type of leadership shows higher effectiveness in alien, role model, passive, and practical types of followership. On the other hand, transactional leadership yields positive impact on practical and conformist types of followership. In summary, personal empowerment plays a direct impact on group empowerment. Thus, with the exception of conformist type of followership, transformational leadership has more impact in human resources of IT SMEs.

The former paper (Part I) studies two methods for searching and determining the simple paths in an acyclic or a cyclic network. The two methods are computer programmed as subroutines (SPLP1 and SPLP2) for various use. And a few examples of its applications are discussed Another paper (Par II) studies the reliability computation for a network by using the Event Space Methods. A computer program is developed for the computation by applying the SPLP2 subroutine subprogram. In this paper the former results are summarized with another computer program for reliability computation by using the Path Tracing Methods. The two subroutines appear in the Appendix as reference for others. The programs can be used in the reliability computation of reducible and irreducible structure networks.

Objectives : This study investigated the health care utilization patterns of workers' compensation insurance(WCI) pneumoconiosis patients with excessively long hospital stays. Methods : The discharge summary data of 3,094 WCI pneumoconiosis patients were analyzed. The study sample was divided into 3 groups based on the length of stay(LOS). Health care utilization patterns were compared among the groups with logistic regression analysis, and the LOS determinants were identified with linear regression analysis. Results : The average LOS of the 222 long stay group patients was 1,448 days. Patients in this group tended to use private general hospitals, were admitted through the emergency room and discharged without the consent of a doctor. Conclusions : Many of the long LOS patients will maintain their inpatient status for the rest of their lives. For quality of life and efficient use of health care resources, policy makers need to establish a policy that enables patients to receive outpatient care in appropriate living conditions outside the hospital.

The aim of this study was to evaluate the readability and suitability of patients' education materials on DM. A total of 34 materials on DM from public health centers, general hospitals, and internet web sites were evaluated for readability by 'graded system of vocabulary', and suitability by 'The Korean version of SAM(Suitability Assessment of Materials)'. On the average, 28.3% of 1st grade reading level words, 27.1% of 5th grade level and over were included in educational materials. For suitability, 6(17.6%) were judged superior, 20(58.8%) adequate, 8(23.6%) inadequate. The reading level of the materials was higher than the recommended reading level(6th grade reading level). For suitability, most of materials were inadequate in some of items such as 'summary or review included', 'context given', 'interaction used'. It is proposed that in the development of patients' educational materials, health literacy of target population should be considered.

In this paper we consider an n-job non-preemptive and identical parallel machine scheduling problem of minimizing the sum of earliness and tardiness with different release times and due dates. In the real world this problem is more realistic than the problems that release times equal to zero or due dates are common. The problem is proved to be NP-complete. Thus a heuristic is developed to solve this problem To illustrate its suitability a proposed heuristic is compared with a genetic algorithm for a large number of randomly generated test problems. Computational results show the effectiveness and efficiency of proposed heuristic. In summary the proposed heuristic provides good solutions than genetic algorithm when the problem size is large.
