This thesis is a study to verify whether the attitude toward retirement perceived by middle-aged workers has a significant effect on retirement preparation and job satisfaction for middle-aged workers in their 40s to 50s working in Seoul and the metropolitan area. As a result, it was found that the forced frustration during the retirement attitude of middle-aged workers had a significant negative (-) effect only on the finances and family of retirement preparation. A new start was found to have a significant positive (+) effect on all sub-variables of retirement preparation. In the second hypothesis, the influence of job satisfaction, it was found that old-age breaks and new start of retirement attitude had a significant positive (+) effect on job satisfaction. As a result, it can be seen that the attitude toward retirement of middle-aged workers who are about to retire has a significant influence on retirement preparation and job satisfaction.

This study investigated the physicochemical properties and chemosensory characteristics of radish samples. Brix results in Matdong-radish showed the highest value (1.5±0.1%), and Mansahyungtong-radish showed the lowest. In terms of salinity, Mansahyungtong-radish had the highest value (1.2±0.1%), and there were no significant differences among samples except Mansahyungtong-radish. In pH analysis, Cheongjunggowon-radish had the highest value at 6.69±0.02. The pH in Mansahyungtong-radish showed the lowest value at 6.10±0.01. In the electronic tongue, sourness was high in the Seoho-radish (8.2), and saltiness was high in the Matdong-radish (8.1). Umami was high in the Seoho-radish (8.3), and sweetness was high in the Matdong-radish (8.1). In the electronic nose, sulfur-containing compounds were high in all the samples. Methanethiol, which represented the odor description of cabbage, garlic, and sulfurous, was abundant in sulfur-containing compounds. Multivariate analysis using physicochemical and chemosensory properties can be used as a database for the food industry.

In this paper, we propose a scheme for improving not only the utilization of frequency bands in the guard channel scheme but also the dropping rate of cognitive radio user in the wireless cognitive radio-based cellular network. The proposed scheme enables cognitive radio users to utilize the guard channel for servicing only handoff calls in normal times, but cognitive radio users must vacate the frequency channel when handoff call appearing. At this time our scheme ensures their seamless services for cognitive radio users, by predicting handoff call's appearance by MMOSPRED (Multi-Media One Step Prediction) method and then reserving the demanded channels for spectrum handoff calls. Our simulations show that our scheme performs better than other schemes; GCS(Guard Channel Scheme) and a scheme without prediction in terms of cognitive users call's dropping rate and resource utilization efficiency.

The purpose of this study was to test the structural relationships among the related variables of university students' satisfaction. This study utilized nation-wide survey data previously collected from 1400 students distributed across 32 universities in Korea. NCSI model was used as a theoretical framework. Using the AMOS 17.0, the structural relationships among six variables were tested, including students' expectancy level, perceived quality, perceived value, satisfaction, complaint rate, and loyalty. The major findings of the study are as follows: First, students' expectancy level had a positive effect on perceived quality; but had no significant effect either on perceived value or on satisfaction. Second, perceived quality had positive effects on perceived value and satisfaction; and perceived value also had a positive effect on satisfaction. Third, students' satisfaction had a negative effect on complaint rate; but had a positive effect on loyalty. Fourth, students' complaint rate had a negative effect on loyalty. The study results imply that among the related variables of students' satisfaction, perceived quality and value of the products work as critical variables, and complaint rate and loyalty directly relate to students' satisfaction. The study suggested that in order to enhance students' satisfaction, universities employ the total quality system and the students' complaints resolution system.

The purpose of this study is to verify the mediating effect of adaptive cognitive emotion regulation and the moderating effect of supervisor's emotional regulation in the relationship between the emotion recognition and negative feedback acceptance of employees. The data was collected from 273 non-managerial workers in various domestic companies. Confirmatory factor analysis was conducted with AMOS 22 to verify the reliability and validity of the measurement tool, and the mediating and moderating effects were examined using SPSS Process Macro to verify the hypothesis. The results of this study are summarized as follows. First, emotion recognition of employees indirectly affects the acceptance of negative feedback through adaptive cognitive emotional regulation. Second, the effect of emotion recognition on negative feedback acceptance is moderated by supervisor's emotion regulation. Specifically, it was confirmed that when the supervisor's emotional control is low, the relationship between emotional recognition and negative feedback acceptance becomes stronger. Based on the results of the study, it was confirmed that the level of awareness of oneself and others' emotions was psychological process of accepting performance-related feedback, and the importance of supervisor's emotional regulation in positively accepting negative feedback. Finally, based on the research results, the academic significance of this study, implications in coaching practice, limitations, and future research were discussed.

새로운 상호작용 장치와 응용 시스템에 대한 유비쿼터스 접근을 위한 요구사항이 창안되어, 사용자 상호작용은 데스크탑 너머로 이동하여 개발되는 경향이 있다. 사용되어지는 응용에서 상황은 시스템을 수행하는 활동의 총체적인 부분이 되었다. 상황 인지를 포함하는 것은 유비쿼터스 접근을 위해서 사용자에게 편리함과 효율성을 제공해 준다. 우리는 상황의 개념이 유비쿼터스 컴퓨팅을 위한 컴퓨팅 상황, 사용자 상황과 물리적 상황의 서로 다른 카테고리로 확장되어져야 한다고 믿고 있기 때문에, 전통적인 HCI 이론은 상황 인지 응용을 개발하는데 부적절하다. 이것들은 확장된 상황 정보를 잘 사용하기 위해 시스템 요구사항 분석과 설계에 있어서 새로운 패러다임을 요구한다. 본 연구에서는 성능 매칭(capability matching)에 의해서 상황 인식 요구사항 분석을 위한 방법과 목표 상황에 대한 상황 인식 속성을 매치시키는 방법을 소개한다. 이런 모델을 근거로 본 연구에서는 몇몇 공통적인 유비쿼터스 접근 상황의 설계 문제를 분석하고 유비쿼터스 관광 응용 요구사항을 고려함에 의해 상황 인지 응용을 체계적으로 적용시키는 방법을 보여준다.

The goal of this study is to contribute to the clinical application by making a quantitative nerve current perception threshold(CPT) examination for the evaluation of numbness that could be occurred after dental surgery, Measurement of CPTs at each different frequencies(2000 Hz, 250 Hz, and 5 Hz) were performed to trigeminal nerve main branch(mandibular division) of 29 patients with dental surgery on mandibular area and 25 normal subjects. There were significant differences in CPTs between patient group and control group.(p<0.05) But, there were no significant between patient male and female in both patient and control group except 2000 Hz was significantly high in the control female.

This study was conducted to identify the impact of adolescents' dietary behavior on their stress perception and provide basic data for education programs linked to customized nutrition education by gender. In this study, the 2019 Korea Youth Risk Behavior Web-based Survey was used, and a total of 57,303 middle·high school students were selected. Controlling adolescents' age, school record, economic status, residence type, subjective health and body type perception, and the dietary life variables designed with breakfast, fresh foods(fruit, vegetables, milk, water), processed foods(carbonate beverage, energy beverage, sweet beverage, fast food) were analyzed to have an effects on the stress recognition of adolescents. Breakfast had a negative(-) effect on stress perception in all genders of adolescents, and in the case of fresh food, water for boys and fruit for girls had the highest negative(-) effect on stress perception, and in the case of processed foods, energy drink was the dietary factor that had the highest positive(+) effect on adolescents' stress perception. These results suggest that it is necessary to develop a dietary education program tailored to the gender of adolescents to improve their stress perception, and to provide continuous guidance to form a healthy diet.
