This paper examines the correlation between midterm and final evaluations using quantitative assessment data from an online liberal arts course titled "Software and Computational Thinking" over four semesters. The course was conducted through pre-recorded video lectures, and the same conditions were maintained throughout the four semesters. The study results showed that the course satisfaction rate in the final evaluations was lower than that in the midterm evaluations across all assessment items. This is likely because improvements based on student feedback from the midterm evaluations were not implemented within the same semester, and the rate of insincere responses increased in the final evaluations. Moreover, objective evaluation items such as "Adherence to Syllabus" and "Relevance of Lecture Content" showed a statistically significant correlation between midterm and final evaluations. However, for assessment items where subjective judgment, such as "Lecture Comprehension", is important, no significant consistency was observed between midterm and final evaluations over the four semesters. The evaluation of subjective assessment items is closely related to the perceived difficulty of the lectures by the students, and in engineering-related courses, this connection is even stronger. Therefore, in the case of liberal arts courses in engineering, where students from various majors are enrolled, it is natural that the perceived difficulty of the lectures differs among students as the course progresses, and that the change in perceived difficulty between the midterm and final evaluations also varies. As a result, it is understandable that there is a lack of consistency in subjective evaluation items between the midterm and final evaluations. These findings suggest that to enhance student satisfaction and maintain consistency in course evaluations throughout the semester in engineering liberal arts courses, it is necessary to design and operate the lectures with differentiated practical content tailored to the academic backgrounds of the students.

PURPOSE. This study aimed to evaluate the clinical performance of implant-assisted removable partial dentures (IARPD) with surveyed crowns, also known as implant-crown-retained removable partial dentures (ICRPDs). MATERIALS AND METHODS. Electronic searches of MEDLINE/PubMed, the Cochrane Central Register of Controlled Trials, the Web of Science, and the Korea Citation Index were performed according to the established search terms for ICRPD. A literature search was conducted for studies published in English or Korean until September 2023, using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. RESULTS. A total of 216 journals were searched, and 31 eligible studies were selected based on the inclusion and exclusion criteria. One systematic review included five case reports of ICRPD. Nine retrospective studies evaluated implant survival/success rate, implant failure cases, marginal bone loss, periodontal status, clinical complications, and patient satisfaction. Twenty-one case reports published in Korea showed good prognoses. CONCLUSION. According to the findings of this systematic review, ICRPD has a reasonable survival/success rate, minimal bone loss, and high patient satisfaction.

This study aims to enhance work efficiency and satisfaction by offering data that make a physical therapist cope with stress coming from the job efficiently by identifying and analyzing the job satisfaction and work stress perceived by a physical therapist, and the level of reaction of a physical therapist. The study distributed survey questionnaires to 300 physical therapists working in medical institutions in Busan via mail and by visit from March 3, 2007 by selecting them simply and randomly from the physical therapist list, and collected the questionnaires by March 20, 2007, 103 respondents were working at 17 general hospitals including a university hospital, 65 respondents at 12 medical centers, and 79 respondents at 39 doctor's offices. The study collected 251 copies, which showed the collection rate of 83.7%, and analyzed 247 copies (82.3%) excluding 4 copies of insincere answers. As a research tool for measuring job satisfaction the study used a tool employed for research into the job satisfaction of physical therapists who work at medical institutions in Gwangju, Jeonnam, and Jeonbuk by Kim Hee-Gwon(1992) and research regarding job satisfaction by Jeong Jeong-Hee(2004) as well as research regarding the factors of job satisfaction by Flippo(1980) & Seberhagen(1970) after adjusting the research tools to the purpose of the study. Also for questions about work stress, the study employed nurses' job stress measurement tool developed by Kim Mae-Ja and em Mi-Ok(1984) by modifying the tool to the purpose of the study, and for a measurement tool for reaction to stress, the study used a tool employed for research into reaction to stress of nurses at general hospitals by Choi Eun-Deok(2005) without modification. For data analysis, the study used the SPSS12.0 as a statistical method, and then used t-test or ANOVA for verifying actual numbers, percentile, average :score, standard deviation, rank, and difference. Also, the study conducted which is a post-test method for variables that show a significant difference at the level of p<.05 level after the analysis. The findings include the following. 1) The respondents' job satisfaction score was 3.21 points on the average (out of 5 full points). The peer relationship ranked the highest, posting 4.02 points on the average, and the job satisfaction with rewards was proven the lowest, posting 2.51 points. For the job satisfaction level by characteristics, there were significant differences (p<.05) in gender, hospital type, weekly working hours, monthly working days, number of patients per day, department in charge of therapy, and number of peers, and there was no significant difference in characteristics other than that. 2) The respondents' work stress score was 2.72 points (out of 5 full points) on the average. The respondents were shown to be under the highest stress when they suffered from excessive workload, posting 3.49 points on the average, and they were shown to be under the least stress when they had a conflict with peers at another department, recording 1.90 points on the average. for the job stress level by the characteristics of job, there was a significant difference in the reflection of job assessment(p<.05). 3) 1n respondents' reaction to stress, most of them were shown to make efforts in coping with stress, posting 2.80 points (out of 5 full points). For their experience of being wider stress, they answered that 'they felt depressed (2.85 points)" for their experience of coping with stress, they answered that 'they were indifferent to it or thought about something else' (2.62 points). Also, for their efforts in coping with stress, they answered that 'they were motivated to remove their strain by taking leave, playing, or using their preferences' (3.52 points), which ranked higher. For the level of reaction to stress by characteristics, there were significant differences by age, gender, marital status, total service years as a physical therapist, monthly working days, and department in charge of therapy(p<.05). It is necessary to offer correct information by conducting an in-depth analysis of the stressful situations of physical therapists who exert efforts in rehabilitating patients at hospitals by factor, and seeking management plans based on the research results. Also, it is necessary to develop a program for coping with stress efficiently for removing stress and to conduct research into the understanding and cooperation of administrators and persons in charge of physical therapists for reducing physical therapists' stress at hospitals.

Along with economic development, the service industry is growing as days go by. Therefore, companies should maximize customer satisfaction through continuous changes by providing services which are suitable for customer needs. The general service industry has a decisive effect on the rate of growth and profitability of a superior business. Therefore, many companies try to provide the best customer service to increase profitability. Because service to a customer is delivered through interactions with the employee, the employee's attitude has a strong influence on the customer's satisfaction level. For these, most service industries are required to provide new types of labor. It is often referred to 'Emotional Labor', and that is different from physical and mental labor. Service providers always provide a service for the customers with a smile, even though they conceal their emotions. The Purpose of this study is to identify theologically the fact of that Sales Workers at Department Stores emotional labor, according to the economization of service, has become to decide the predominance of competition among companies and represents the quality of service ; to confirm that their emotion management is a crucial part of the work; to identify the correlation among job stress and job satisfaction which are experienced in the process of performing display rules required by organization. To practice them, this study deals with the theological consideration of the emotional labor, job stress and job satisfaction. This study proceeded to evaluate how the emotional labor of sales workers at department stores effected on their job stress and satisfaction. The result of this study will be summarized below. First of all, the frequency of emotional display and attentiveness required to display emotions both have a similar effect on the level of job stress. In the case of the emotional dissonance, there isn't a great amount of proof that it effects the job stress. That shows us that the aspect of the latter, they express the feelings on their daily lives less than the former by the public awareness and gaze. so, once they could accept the latter, the effect on the job stress would be vanished. Second, a study was performed to figure out the effect of emotional labor on job stress. As a result, none of them make negative effects on the job satisfaction but the attentiveness to required display rules even have positive effects on it. that means the emotional labor has an indirect effect on the job satisfaction through some intermediation stuff. Third, the role conflict of job stress factors has a negative effect on job satisfaction, Although role ambiguity has a negative effect on that as well, I couldn't find appropriate proof for that. As far as I figured out, job stress can only increase job dissatisfaction. In other hands, the sales workers would have tendencies to have more motivation to work hard rather than reveal their job stress and complain about work. Finally, emotional laborers always work close to job stress. This can maximize service for the customers, but it increases stress of the laborers providing services at the same time. Then, they can not provide high quality service. It is no doubt that we need to begin managing it systematically. In conclusion, the work satisfaction of the sales workers is connected to the service quality for the customers directly.

Purpose: This study was done to develop a schematized alarm-managing manual for continuous renal replacement therapy (CRRT) and to investigate its effects in maintaining continuity in the patients' treatment and promptly resolving alarms when CRRT is being carried out. Methods: Sixtynurses from two medical intensive care units (ICUs) (one experimental and one control) at one hospital were asked to answer a questionnaire including their CRRT nursing competency and satisfaction with the manual. Data on alarm resolution rate were collected by analyzing existing data, such as the details of each alarm and the number of resolutions around the clock in the CRRT device. Results: The alarm resolution rate and some of CRRT nursing competency scores in the experimental group were higher than those in the control group. The experimental group was also satisfied with the manual. Conclusion: The study confirmed that the schematized alarm-managing manual can be useful for ICU nurses to resolve alarms and can be used as a guideline. Application of this manual to clinical practices and its use can therefore, be encouraged through continuous education and promotion.

A three-channel radio frequency (RF) monopulse receiver using a data signal with a maximum transmission rate of 274 Mbps was designed. A monopulse receiver using a broadband communication signal was designed to operate in the Ku band, and it consists of a down-conversion module and a signal-processing module. To satisfy the performance of the proposed RF monopulse receiver, a signal-processing function less than the reception sensitivity for each transmission rate according to the adaptive transmission rate is required. To minimize signal reception and mutual frequency interference of various bandwidths, two RF filters were applied. To verify the satisfaction of system requirements, an AWR Corp. simulation tool was used.

The purpose of the study was to investigate the level and the major causes of job stress, and the causes of the high level of job turnover rate of fashion merchandisers and fashion designers. The study also examined the correlations among the major causes of job stress, job results and job turnover rate. A part of the questionnaire consisted of questions on major causes of job stress, job result, and intention and trial to leave a job. The subjects were to rate on 5 point Likert-type scales. The other part included the questions on demographic and individual characteristics of the subjects and their company characteristics. For the survey, the subjects were 99 fashion merchandisers and 128 fashion designers who are employed by mens or womens wear manufacturers. The SAS PC+ package was used to calculate frequency, Cronbach $\alpha$, multiple regressions. The results of the study were as follows: 1. The high degree of the job results were resulted from the high degree of specialties in their job characteristics, high contentment in human relations, career development and income, and low role conflict. 2. Stronger intentions and more trials to leave their job were correlated to better task performance in the workplace, lower commitment to their job, and lower job satisfaction. 3. Higher level of job stress caused by interpersonal relationship in the organization and contentment in career development and income affected stronger intentions and more trials to leave their job.

Women in the predominantly male-oriented college of engineering which is afflicted by the high dropout rate and the low employment rate of coeds in their majoring fields because of the die-hard male dominant culture. In order to resolve the related problems, P University has been actively engaged in a movement called "Women into Engineering" (WIE) to raise the gender cognitive awareness and to train women engineers for highly qualified work force. As part of the movement, a subject called "Women in Engineering" that focuses on the gender cognitive perspective is effective to reduce the dropout rate and to land a job inside their fields by stimulating their interest in their specialty and masting soft/hard skills. The study was conducted a survey of the coeds who have completed the "Women in Engineering" course to evaluate the degree of satisfaction perceived, and a t-test through comparing the group of the coeds and a group of coeds who have not taken the course. The results showed statistically significant responses indicating that both groups of coeds would like to see WIE offer more basic engineering courses like "Women in Engineering". This may lay the foundation to offer other major engineering courses for juniors and seniors that emphasize the gender cognitive approach.
