Objectives: An increase in the number of caregivers is necessary to provide services to the elderly, but more importantly, it is qualitative management for them. The purpose of this study was to identify occupational stress, job satisfaction, and organizational commitment and to explore the impact of occupational stress on job satisfaction and organizational commitment among caregivers employed in health service centers for the elderly. Methods: This descriptive survey was a cross-sectional correlational design of 118 caregivers. The questionnaire included occupational stress, job satisfaction, and organizational commitment. Stepwise multiple regression was applied. Results: Job satisfaction and organization commitment of caregivers were found to be above the average. There was a high level of job stress due to lack of job autonomy, job demands, and inadequate compensation. It has been found that the inappropriate compensation, organization system, work culture, and lack of job autonomy affected job satisfaction of caregivers. The factors affecting organizational commitment were inadequate compensation, job insecurity, and work culture. Conclusions: Efforts should be made to assess and complement the appropriateness of compensation and work culture that are taken to relieve job stress to enhance the job satisfaction and organizational commitment of caregivers.

The purpose of this study is to investigate the effects of the job stresses perceived by R.O.K. naval crews on turnover intentions and job satisfactions. Especially, this study aims to derive the policy implication for the trait characteristics by comparing the job attitude between the surface naval ship and submarine crew. For this purpose, we surveyed 1,000 naval crews. Then, multiple regression analysis was performed. Next, a T-test was conducted to test statistical significance of group differences. First, the job stresses perceived by naval crews were higher in the order of physical environments, overworks, compensation incompetence, lacks of autonomy, and conflicts with people. Second, the job stresses perceived by submarine crews were higher than that of surface naval ship crews. It was also proved statistically significant by the T-test. Third, the physical environments, lacks of autonomy, conflicts of relativity, and inadequate compensation stress have a positive statistically significant effect on turnover intentions of naval crews. Fourth, lacks of autonomy, conflicts of relativity, and inadequate compensation factors have a statistically significant negative effect on the job satisfactions of naval crews. Finally, multiple regression analysis was performed between the independent and dependent variables of the naval crews, and the policy implications were derived.

Purpose: The purpose of this study was to identify Relationship between job stress and job satisfaction of dental hygienists Methods: The subjects of this study were to 173 dental hygienists who work in dental diseases and clinics in Busan, Ulsan, and Gyeongnam, and through the Internet link using web questionnaire from August 1 to October 30, 2023. Distributed and collected. The collected data were analyzed using an IBM SPSS ver. 26. Results: As for general characteristics, job stress was high in the 40s age group, work experience was high in the 1-4 year group, and job satisfaction was high in the 4-7 year or more group. As factors affecting job satisfaction, it was found that the lower the Self- determination of duties , the lower the Job insecurity, and the lower the Inadequate compensation, the higher the job satisfaction. Conclusions: From the above results, in order to increase the job satisfaction of dental hygienists, it is necessary to ensure stable employment and at the same time allow them to focus on tasks specific to dental hygiene, as job satisfaction decreases if a lot of chores unrelated to dental hygiene work are performed, and Self- determination of duties and an appropriate compensation system must be established. If an excessive workload is given or there is frequent overtime work, compensation should be made commensurate with experience or ability, and in the case of frequent overtime work, appropriate compensation should be provided through allowances or incentives.

Media ADR is currently emerging as one of successful cases in South Korea while environmental ADR was known not to satisfy both defendants and offenders. Thus, this paper is intended to present proper remedies for typical compensation schemes of environmental ADR by comparing the two ADRs regarding legal reservation of compensation clause. It was found that the media ADR helped clients achieve a more fast and easy dispute resolution by providing compensation standards based on various categories such as types and scopes of compensation. However, the compensation scheme of environmental ADR brought out public complaints and inadequate services due to inconsistency and instability in terms of legal reservation. The results indicate that the compensation clause based on the reservation of laws in media ADR could be used not only as a checklist to confirm limitations of environmental ADR, but also as realistic evidences to adjust the compensation standard systematically that is under development and requires remodelling. As a result, the research findings have opened the new possibilities of "the quality assurance of environmental ADR based on the domestic legislation", proposed as an initial aim of this paper.

In this paper we apply PMC (parallel model combination) to speech recognition system online. As a representative of model based noise compensation techniques, PMC compensates environmental mismatch by combining pretrained clean speech models and real-time estimated noise information. This is very effective approach for compensating extreme environmental mismatch but is inadequate to use in on-line system for heavy computational cost. To reduce the computational cost and to apply PMC online, we use a noise masking effect - the energy in a frequency band is dominated either by clean speech energy or by noise energy - in the process of model compensation. Experiments on artificially produced noisy speech data confirm that the proposed technique is fast and effective for the on-line model compensation.

Purpose: This study aimed to examine the process from occurrence of a hospital nurse's suicide to workers' compensation approval, responses of the parties involved, issues debated during approval deliberations, and significant policy changes resulting from the incident. Methods: We conducted in-depth interviews with involved parties and collected various documents, including newspaper articles, forum proceedings, and the agency report on determination of workers' compensation. Content analysis was performed on the collected data. Results: A Joint Task Force continuously reported its progress and findings through mass media such as newspaper, radio, and TV. These activities exerted pressure on a government agency to conduct an occupational disease review and significantly impacted the workers' compensation approval. The agency recognized associations between the hospital's inadequate nurse training and the suicide but did not confirm the excessive overtime and workplace harassment experienced by the nurse as causes of the suicide. This case's media coverage and impact resulted in a law prohibiting workplace harassment and a hospital system dedicating at least one nurse to training activities. Conclusions: This incident had a significant social impact as the first case of workers' compensation approval for a hospital nurse's suicide. However, the case produced no structural changes in nurses' working conditions such as heavy workloads.

This study intends to closely examine an evaluation of effectiveness of the HRM associated with interactions among employees(I), purpose recognition(P), role feedbacks(R), and motivative compensation(M). The following is a summary of the results of this research: From the study of the actual situation of the human resource management by the Korean firms, it appeared that the form of existence of vision systems possessed the form of having been written as documents and co-shared. And, although, in the area of motivation endowment and feedbacks, the level of motivation endowment regarding the comprising member by those in charge of departments and the level of reflection of the company's personnel policies in the execution of work by the departments were ordinary, the level of presenting the opinion of the departments regarding the company's personnel policies was shown to be low. And, the decisive elements of wages and the compensation standard were in the order of performance basis and long service. Also, it was analyzed that the leadership style of the CEO is the most important element that influences human resource management policies. And, it was analyzed that in the evaluation of the human resource management area the roles regarding evaluation and compensation, especially, the mutual interactions of the comprising members, feedbacks, and improvement activities are inadequate. And the managerial implications are discussed.

본 논문에서는 OFDM 기반 무선 LAN 시스템에서 긴 훈련심볼을 이용하는, 시간동기 오차의 영향이 고려된 IQ imbalance 추정 및 보상 기법을 제안한다. 기존의 긴 훈련심볼을 이용한 IQ imbalance 보상 기법은 시간동기 오차에 민감한 구조를 갖기 때문에 시간동기 오차가 필연적인 실제 시스템에서는 심각한 성능 저하를 보인다. 본 논문에서는 시간동기 오차로 인해 발생하는 위상회전을 상쇄시킬 수 있는 새로운 criterion을 정의하고, 이에 따른 IQ imbalance 추정 및 보상 기법을 제안한다. 제안된 기법은 시간동기 오차가 존재할 경우에도 IQ imbalance 의 영향을 이상적인 경우 대비 최대 0.2dB 이하로 보상할 수 있으며, IEEE 802.11a 시스템의 54Mbps 전송모드에 적용하였을 경우 기존 기법에 비해 약 4.3dB의 성능 이득을 보인다. 제안된 기법을 이용한 IQ imbalance 추정 및 보상단은 Verilog HDL을 이용하여 하드웨어 설계 및 검증 되었으며, 0.18um CMOS 공정을 이용하여 합성한 결과, 약 75K gates 와 6K bits의 메모리로 구현되었다.

This paper addresses a novel noise-compensation scheme to solve the mismatch problem between training and testing condition for the automatic speech recognition (ASR) system, specifically in car environment. The conventional spectral subtraction schemes rely on the signal-to-noise ratio (SNR) such that attenuation is imposed on that part of the spectrum that appears to have low SNR, and accentuation is made on that part of high SNR. However, these schemes are based on the postulation that the power spectrum of noise is in general at the lower level in magnitude than that of speech. Therefore, while such postulation is adequate for high SNR environment, it is grossly inadequate for low SNR scenarios such as that of car environment. This paper proposes an efficient spectral subtraction scheme focused specifically to low SNR noisy environment by extracting harmonics distinctively in speech spectrum. Representative experiments confirm the superior performance of the proposed method over conventional methods. The experiments are conducted using car noise-corrupted utterances of Aurora2 corpus.

Ferrokinetcs by Pollycove's method on 2 cases of Chronic myelogenous leukemia were presented in order to study the erythropoietic function and pathogenesis of anemia. The results are as follows. (1) The daily hemoglobin syntheses were slightly elevated. Both the mean effective hemoglobinization time and mean erythron life span were shortened. The maximum net ROC incorporations of $^{59}Fe$ weere decreased. The in vivo surface measurements of radioactivity over liver, spleen, and sacral bone marrow revealed findings consistant with hemolysis and extramedullary hematopoies. (2) Based upon those findings it is assumed that anemia in chronic myelogenous leukemia may result from hemolysis and inadequate compensation to the developing anemia.
