In this study, we evaluated to the superiority of treatment techniques on prostate cancer, apply to each other treatment techniques-3D conformal therapy versus IMRT-using dose distribution and dose coverages. Obtained 10 patients CT simulation, divided tumor volume and critical organs. Prescription dose was 80 Gy on tumor volume and Each of plans was set by two different plans. As a result, Dose coverage was superior to IMRT. The IMRT's tumor absorbed dose(100.2%) was close to prescription doses. Normal tissue(bladder, rectal, bowel Lt Rt fumoral head) absorbed dose rate was superior. In other words, the radiation therapy of prostate cancer with intensity modulated radiation therapy was better than conformal radiation therapy on dose.

As the era of autonomous driving approaches, it is expected to have a significant impact on our lives. When autonomous driving cars emerge, it is necessary to develop an index that can evaluate autonomous driving cars as it enhance the productive value of the car by reducing the burden on the driver. This study analyzed how the autonomous driving era affects commuting time and commuting time satisfaction among office goers using a car in Gyeonggi-do. First, a nonlinear relationship (V) was derived for the commuting time and commuting time satisfaction. Here, the factors affecting commuting time satisfaction were analyzed through a binomial logistic model, centered on the sample belonging to the nonlinear section (70 minutes or more for commuting time), which is likely to be affected by the autonomous driving era. The analysis results show that the variables affected by the autonomous driving era were health, sleeping hours, working hours, and leisure time. Since the emergence of autonomous driving cars is highly likely to improve the influencing variables, long-distance commuters are likely to feel higher commuting time satisfaction.

This study was conducted to provide a basis for developing strategies to improve the intention to quit smoking by identifying the factors affecting the smoking cessation intention of male smokers living in Seoul who have not tried to quit smoking in the past year. The components of the planned behavioral theory were used to identify the influencing factors. The research data were analysed secondary data used in the study performed by the Korea Centers for Disease Control and Prevention in 2020. As a result of the univariate analysis, the factors affecting the smoking cessation intention rate were the average daily smoking amount and the components of the TPB. As a result of multivariate logistic regression analysis, the subjective norm and the perceived behavior control factor among the components of the TPB had statistically significant differences. Therefore, in order to increase the intention to quit smoking, it would be effective to use strategies that strengthen the strong recommendations from significant others and the smoker's self control.

This study empirically examined the relationships among ethical leadership, supervisor identification(SI), affective commitment(AC), and unethical pro-supervisor behavior(UPSB) based on social learning theory and social exchange theory. The data were collected by conducting a survey of 339 workers and analyzed using SPSS25 and SPSS Process Macro (v3.5). The results were as follows. First, ethical leadership directly negatively influences UPSB. Ethical leadership indirectly positively influences UPSB mediated by SI. Second, ethical leadership, completely mediated by AC, indirectly positively influences UPSB. Third, ethical leadership has an indirect positive effect on AC mediated by SI. This study showed how ethical leadership works in organizations through social learning theory and social exchange theory. Also, it suggested implications on how to use ethical leadership in field.

The purpose of this study is to help female office workers in relieving their stress in rapidly changing modern society and maintaining a healthy and beautiful life by analyzing the complex effects of alternative beauty therapy on stress relaxation targeting 50 female office workers in their 30s to 40s, usually showing a high stress index due to their work. Aroma therapy and dry relax massage were carried out for 15 minutes as a beauty therapy, and stress index of the subjects was confirmed through survey before performing the beauty therapy. The experiment was conducted once a week for four weeks, and the cortisol concentration in saliva was analyzed for the outcome measurement. As a result, average stress index was 3.97 which showed a high value, and the cortisol concentration of the subjects after the experiment decreased significantly (p<0.05), and especially subjects who were married and had caregiving responsibility showed more changes in their cortisol concentration. The above result shows that dry relax massage using aroma is highly effective for mind and body relaxation of women in their 30s to 40s who are significantly stressed. If such beauty measures are applied properly, it is judged to be helpful for managing the stress.

In this study, we expected the perceived difference of job calling and decent jobs between recent generation and baby-boomer and eco baby-boomer generation. Understanding perceptions of jobs by current generation that are perceived as lifetime jobs rather than lifetime workplace will make some valuable contributions to future job research and policy. The aim of the study was to examine the subjective perception of decent jobs among university students who are ready to go to labor market. By using Q methodology, we extracted 291 Q statements and 47 Q samples. In addition, 31 subjects classified Q samples into Q distributed tables. We used Ken-Q Analysis program. In the results, we found five types of perceived subjectiveness on the decent jobs, which were interests-seeking, balance-seeking, toward organization, power-seeking, and career development. These results confirm the diversity of perceptions of decent jobs. Then, we suggested policy implications to help the labor market entry based on the results.

This study analyzed the conflict plots of the top 5 most watched TV series during the 2000-2005 period. It was observed that those popular series typically took love and success as main subject matters to actually aim for such a sensitive social issue as the widening gap between the rich and the poor as well as audience's desire for higher status. They even dared to describe our lives at home and the job as power relationships to heighten the intensity of the conflict. On the other hand, the resolution took a wide variety of both positive and negative endings - ranging from marriages and conciliations to death and arrests - as a way to have the antagonists punished. The deus-ex-machina was often used. A chronological view of the change in the conflict plots of successful dramas should deserve further academic interests.
