Tea is one of the three most consumed drinks in the world along with coffee and cocoa, and it represents culture and tradition. There are more than 1,000 tea-related smartphone applications registered in the Apple App Store and Google Play. This study examined, for the consumers of the 20's, if there are differences in consumer preferences for tea-related applications based on gender, age, tea consumption amount and tea drinking duration. Based on surveys of 169 tea consumers, this study found that there were significant differences in consumer preferences for tea-related applications based on age and tea drinking amount. The applications of 'tea places,' 'entertainment,' and 'tea timer' were preferred by the consumers of 20's and 'etiquette,' 'tea ceremony,' 'teaware,'and 'tea information recording' were favored by the consumers of 30's and older. The consumers with higher drinking amount showed higher preferences for tea etiquette related applications. There were no significant differences for tea-related applications based on gender and tea drinking duration. The result of the study is expected to contribute to the development of tea related applications with higher appeals to consumers as well as traditional Korean drinks.

The purpose of this dissertation was to investigate how college students' adjustment (CSA) affects their career decision (CD), based on analyses of the relationship between college students' adjustment and their career decision. For the purpose of articulation of the relationship, this study implemented factor analysis to find out the sub-factors of CSA and those of CD and developed conceptual frameworks for CSA and CD. As results, this study reveals that, at first male students had higher scores in the affective adjustment scale and the olders and the higher graders had higher scores than the youngers and the lowers. Secondly, freshmen showed higher scores in relation to the career decision withholding factor. With regard to students' regret for career decision, 19 to 20 year-old-students demonstrated higher scores. Thirdly, students had lower scores in the career decision withholding factor and in the factor of regret for career decision when they had higher scores in social adjustment. Students scored higher in affective adjustment they scored lower in regret for career decision. Also, they scored higher in the factor of career decision stability when they had higher scored in the factor for personal relationship.

This study explained about the different motive of partner homicide and this homicide's elements which are feature of human sociology, home environment, school life and partner's trouble causes. After analyzed these element which affect to the motive of partner homicide, we couldn't find statistical differences of partner homicide motive by sex, having a job. However, there are small gap in an age group. Almost the homicide by expressive motive was a primary factor in the whole mass but, in the age of 40's, 11.1% is by the homicide of instrumental motive in the partner homicide. We need some more detail analysis and the partner murderer who growed up in very poor home circumstances commit Homicide by 100% expressive motive. This result suggested that murderer who was in the inferior home environment can do murder more easier than normal because of their emotional reason which are urgent, impulsive and contingent. On the other hand, their school life behavior during a growth process was useless for explain the motive of partner homicide. On one side, we could confirm that partner's trouble cause is a very useful element for explain the partner homicide, that is, if the if the level of conflict with partner's were high, the murder by expressive motive will grow up. But we must see the fact that the partner homicide's rate is 13.3% by instrumental motive in the low trouble causes very carefully for understand the partner homicide.

In this study a practical guarding work is carried out for 180 minutes as the same as the actual guarding work that is done by nine students of the department of security services in K University in order to investigate changes in circadian rhythms during long hour guarding in bodyguards at practical sites. In the results of the tests of the heart rate variation and autonomic nervous system with the interval of 30 minutes using HRV (Heart rate variability), there are no significant differences in HRV and SDNN and that leads to maintain it stably during the guarding work for 180 minutes. In the case of TP which reflects the overall activity level in the autonomic nervous system, it shows a high significant difference (p<.05) at 90 and 120 minutes compared to that of normal states. Also, it shows a significant decrease in the level after a lapse of 120 minutes and that shows a decrease in the activity of the autonomic nervous system for the guarding work more than 120 minutes. Although differences in VLF, LF, and HF are not significant levels, these are influenced on the change in TP. The LH/HF ratio that represents the balance between the sympathetic nerve and the parasympathetic nerve shows a significant high level (p<.05) after a lapse of 30 minutes. Thus, it is considered that the concentration of the guarding work after a lapse of 120 minutes is decreased and there are some tensions and excitations after a lapse of 30 minutes since the beginning of the guarding work.

This study aims to empirically analyze the police officers' recognition on performance of the patrol division system. For this purpose. Firstly, the study discusses the theoretical aspects of the patrol division system and its performance. Secondly, the analytical framework is formulated based on three levels developed for performance of the patrol division system such as efficiency of the patrol division system, partnership between police and citizen, and police officers' job satisfaction. The major findings of this study could be summarized as follows; Firstly, The level of the efficiency is below the average in all factors. Secondly, In relation to partnership between police and citizen is below the average in the level of the citizens' preference and partnership. Thirdly, the level of job satisfaction is normal. Fourthly, compared in the level of the areas, there is a difference in the recognition on four factors in efficiency and three factors in partnership. Finally, the direction of raising the level of performance of the patrol division system is explored.

The purpose of this study was to determine the relationship between gymnasium selection and training adherence of security martial arts trainees. To this aim, this study selected 8 gymnasiums in Gyounggi and Incheon province and sampled 220 people above the fourth grade in elementary school. Out of these, 14 cases were dropped due to insufficient answers or incomplete answers, and 206 qualified cases were finally adopted for this study. Data were analyzed using exploratory factor analysis, reliability analysis and frequency analysis, MANOVA, correlation analysis and multiple regression analysis with SPSS 18.0. The results of this study were as follows. First, there were significant differences in gymnasium selection factors(instructor background, training program, public relations) depending upon the trainee's sex. Second, there were significant differences in gymnasium selection factors(training program, main others, public relations) depending upon the trainee's school grade. Third, there were no significant differences in training adherence factors depending upon the trainee's sex and school grade. Fourth, there were positive correlations between instructor background, training program and public relations-factors among gymnasium selection and management program, external and social relations-factors among training adherence. Fifth, the partial sub-factors of gymnasium selection have influenced training adherence. Consequently, security martial arts managers and instructors need to establish marketing strategies suitable for sex and school grade to recruit new security martial arts trainees. It may be considered that security martial arts instructors should construct the differentiated management system for trainees and the specialized training program for lasting training of new or existing security martial arts trainees.

The primary aim of this study is to provide effective operational directions of multi-purpose maneuver patrol via practical analysis on the fear of crime and its impact factors in the Hot Spots Policing target region. Comparative Analysis on fear of crime and its impact factors such as informal social control, disorder, and the perception of police activities is conducted in regions of maneuver patrol against its neighborhood. In Conclusion, no evident differences in fear of crime between the regions of maneuver patrol and its neighborhood were found. However, regions of maneuver patrol displayed significant distinctions in informal social control and perception of crime frequency in comparison to its neighborhood of no such patrol. In addition, it was noticed that in both regions disorder and perception of crime frequency served as the impact factors of fear of crime, which in part exhibits positive relationship with perception of hot spots policing. This study concludes that criterion in deciding on the regions of maneuver patrol should include subjective impact factors such as fear of crime. Furthermore, it suggests that along with the current unsatisfactory maneuver patrol system there needs specific guideline to enhance the perception of police activities including strengthened interactions with residents, improvement in social disorder.

Sargassum horneri is one of the floating algae in the sea, which breeds in large quantities in the Yellow Sea and East China Sea and then flows into the coast of Republic of Korea, causing various problems such as destroying the environment and damaging fish farms. In order to effectively prevent damage and preserve the coastal environment, the development of Sargassum horneri detection algorithms using satellite-based remote sensing technology has been actively developed. However, incorrect detection information causes an increase in the moving distance of ships collecting Sargassum horneri and confusion in the response of related local governments or institutions,so it is very important to minimize false detections when producing Sargassum horneri spatial information. This study applied technology to automatically remove false detection results using the GOCI-II-based Sargassum horneri detection algorithm of the National Ocean Satellite Center (NOSC) of the Korea Hydrographic and Oceanography Agency (KHOA). Based on the results of analyzing the causes of major false detection results, it includes a process of removing linear and sporadic false detections and green algae that occurs in large quantities along the coast of China in spring and summer by considering them as false detections. The technology to automatically remove false detection was applied to the dates when Sargassum horneri occurred from February 24 to June 25, 2022. Visual assessment results were generated using mid-resolution satellite images, qualitative and quantitative evaluations were performed. Linear false detection results were completely removed, and most of the sporadic and green algae false detection results that affected the distribution were removed. Even after the automatic false detection removal process, it was possible to confirm the distribution area of Sargassum horneri compared to the visual assessment results, and the accuracy and precision calculated using the binary classification model averaged 97.73% and 95.4%, respectively. Recall value was very low at 29.03%, which is presumed to be due to the effect of Sargassum horneri movement due to the observation time discrepancy between GOCI-II and mid-resolution satellite images, differences in spatial resolution, location deviation by orthocorrection, and cloud masking. The results of this study's removal of false detections of Sargassum horneri can determine the spatial distribution status in near real-time, but there are limitations in accurately estimating biomass. Therefore, continuous research on upgrading the Sargassum horneri monitoring system must be conducted to use it as data for establishing future Sargassum horneri response plans.

This research analyzed how the new and senior security guards employed privately are influenced on their task performance by the factors operated before task performance: cognitive state anxiety, physical state anxiety and state confidence which are the sub-factors of the Competitive State Anxiety(CSAI-II) according to the educational background, career, gender and athletic capacity. First, as for the new and senior security guards' state anxiety before task performance, the senior guards felt the cognitive anxiety more than the new guards, but there was not a distinct difference statistically. Therefore, it is estimated that there is little difference in the level of cognitive anxiety between the new security guards with insufficient career and the seniors. Second, the level of the physical state anxiety was shown higher from the senior guards than from the new ones and had a distinct difference. However, it seems to be derived from the extent of physical development as the seniors are at the time of vigorous physical development. Third, the level of state anxiety had no distinct difference between them statistically though the new security guards felt it higher than the seniors. Fourth, the state confidence was shown higher from the seniors than from the new and had a distinct difference statistically, also. Fifth, as for gender, the male and female guards did not have a difference so much in the cognitive and physical state anxiety, and state confidence. Sixth, as a whole, the state anxiety was highest as for the security guards with athletic capacity level 1 and 2. Those with the level 2, and 3 and the level above 7 felt it less than those with the level 5-6, which had a distinct difference in statistics. The manager of the new and senior security guards should make them dispel anxiety in piece of mind through physical and mental education encouraging them to have self-confidence, practical training, and psychological training based on the analysis of causes of various cases.
