This study (research) has been done on the job, job-satisfaction and job dedication of body guards from many sectors in Korea. This research is focused on the relationship of job, job-satisfaction and job-dedication in diverse aspects in order to build up a detailed theory, As a result, teams of body guard can enhance their systematic efficiency through the theory. Therefore in this chapter, it will re-examine the result of this research and discuss about the theoretical and practical aspect of the result. This study(research) will be the outset(start) for the organizational behavior study of the body guards in Korea. Especially, this research tries to distinguish the duty aspect and the general feature of the body guards, satisfaction along with the level of dedication. Therefore it will give the persons concerning the bodyguards many theoretical and practical points to consider. But there is a limitation as crossing research that in this research we didn't research in compensation for all internal body guards and accomplishment of research has achieved in a short-time. Though it will be necessary to accomplish in henceforth research, if at all possible, in compensation for all body guards and much more diverse security service classification, also for a long time extended vertical research.

Assessment of NPP(Nuclear Power Plant) decommissioning cost is very important for safe decommissioning of nuclear power plants. In the United States, which has the most NPP decommissioning experience, the cost evaluation study has been conducted since the 1970s in order to decommissioning nuclear facilities. The US NRC has conducted studies on decommissioning technology, safety and cost for a variety of reactor type and nuclear installations. In the total decommissioning costs, the end of operation licenses accounted for the largest portion, followed by spent fuel management and site restoration. In case of immediate decommissioning, spent fuel management cost increased compared to delayed decommissioning, and delayed deocmmissioning increased the cost of terminating the operation license. However, in general, delayed decommissioning does not show any significant benefit as compared with immediate decommissioning. It is necessary to consider the evaluation according to the site conditions when evaluating the cost of decommissioning domestic nuclear power plants. Also, in Korea, IAEA recommendations were applied to reorganize the radioactive waste classification system. Therefore, it is necessary to develop a method to appropriately use the decommissioning data of the preceding US Nuclear Power Plant in the new classification system when estimating the amount of radioactive waste generated during decommissioning. In particular, the establishment of the evaluation methodology for the waste to be disposed of will be an important factor in securing the accuracy of the decommissioning cost. In addition, it is necessary to construct information data that can be applied to facility characteristics and work characteristics in order to evaluate the cost of demolition of domestic nuclear power plants.

The historical study reveals that our ancestors had maintained a system which could produce data on the number of population and households as well as on their characteristics. For example, such data on age structure of the population, number of births, number of deaths by age & sex, number of in & out migrants were found in an historical document for the year 755. The main purposes of maintaining the system at that time were taxation and conscription. As the system evolves, another function of identifying the legal status of people was also added. Looking into the figures for those days reveals that ommission rates of the number of population and households were high. Thus, in an effort to obtain a reliable data, the annual population survey system was introduced as of 1 September 1896. This date is now cerebrated as the Statistics Day. Since then, the survey system has been diversified. At the present time, there are three major data sources which produce the statistics on population and households: Civil Registration System (vital statistics), Resident Registratiton System (migration statistics) and Population Census. However, these three systems are found to have some problems to produce the accurate data. There are some inherent problems in the registration systems such as problems in its coverage, accuracies in contents and timeliness in reporting the vital events and publishing the results. The population census has also non-sampling errors such as errors in coverage, response and non-response. Apart from the above mentioned problems, there are also conflicting problems arised from having different three data source. We can find some overlapping problems in laws and difficulties in comparative studies between regions. In the future, these problems should be taken into consideration for the improvement of the quality of statistics on population and households.

Compared to pavement of Chinese palace gardens, those of private gardens in south part of the Yangtze River(長江) in China shows variety of patterns. In order to figure out what causes the difference in paving pattern, this article focuses on the traditional Chinese ideologies during the all time. An analysis on 'Classical Gardens of Suzhou', which has been designated as UNESCO World Heritage, was used to determine how ideologies have influence on paving pattern of Classical Gardens. As a result, various Chinese ideologies such as Nature worship, Totemism, Confucianism, Taoism, Buddhism, and Folk Culture were found in paving patterns of the private gardens. Pattern of sun in the Retreat & Reflection Garden(Toisawon) is an example of Nature worship among primitive beliefs of ancient China. Phoenix pattern of the Couple's Retreat Garden(Ouyuan, Liuyuan) reflects Totemistic beliefs. Confucianism is the underlying philosophy of Eight Square pattern, Six Square pattern, and Cross Square pattern. These patterns were mainly used to pave large area and easily found in many gardens. Patterns reflect Taoism are "Wufu holding life" pattern(the Five blessing holding life, 五福捧壽), Flat peach pattern, and Alluding Eight Immortals pattern. Paving patterns related to Buddhism are patterns of 'Eight treasures' and Endless knot pattern appears most frequently since it expresses concept of reincarnation well. Paving patterns shows folk culture and beliefs of the time in China are bat, butterfly, dragonfly, frog, carp, and coin(ingot).

The purpose of this study is to analyze the operating case of admission officer system of colleges and universities in USA, and to deduce its implications to Korean colleges and universities. In order to accomplish the purpose of this study, following methodologies were adopted: review on the related literatures, statistical data, and previous studies concerning admission officers of colleges and universities in USA, and in-depth interview with them. Historical and cultural background of university admission system of USA was analyzed. Case study on USA colleges and universities was divided with four parts such as determining factors of admission and admission methods, organization for admission affairs and its number of persons, work of admission officer and admission process, and cost of admission and salary. Implications to Korean colleges and universities were presented with three points such as overall implication, implication on materials for admission process, and implication on managing system of admission. Based on the analysis, discussion and implications, the conclusion and further suggestion of this study are as follows: First, actual authority of admission should be grant to admission officer. Second, not only non-curricular factors but also scholastic factors should be emphasized in role of admission officer. Third, education and training about work of admission officer and unification of criteria for admission should be held. Fourth, admission officers with various occupation background are needed. Fifth, work of admission officers should be extended to various work concerning university entrance. Sixth, cross-checking on marks of over two admission officers is needed. Seventh, in order to stabilize admission process, status of admission officer should be stabilized. Eighth, part-time admission officers are need to employ in season of admission. Ninth, authority of weighting high schools should be grant to admission officers in long term perspective.

The paper investigates the ideal image and the ideological tendency of the traditional intellectuals in the East Asian Societies by analyzing the religious thoughts of Donghak, Tenrikyo and the Society of God Worshippers, which were the representative religious bodies in Korea, Japan and China. In particular, this paper focuses on the founders' thoughts of the religious organizations, such as Choi Jewoo(崔濟愚, 1824-1864) of Donghak, Nakayama Miki(中山みき, 1798-1887) of Tenrikyo and Hong xiuquan(洪秀全, 1814-1864) of the Society of God Worshippers. The results obtained from the study are as follows:Choi Jewoo's father was a teacher in a rural village, and so Choi Jewoo also wanted to be a teacher. Afterward when he had religious experiences, in the trance state, he became a teacher. Consequently, his religious thoughts were based on the ideal teacher's stance. Nakayama Miki respected her father, who was a low-ranking warrior or bushi(武士). And when she experienced strange experiences, she became a high-ranking warrior or shogun(將軍). On this account, many of her religious thoughts were based on the ideal bushi's position. Hong xiuquan's father was a low-ranking local official, therefore Hong xiuquan wanted to be a high-ranking official since childhood. Later, he took the civil service examinations only to failed. And so when he had religious experiences, he became an official appointed by God. And his religious thoughts, in many cases, depended on the ideal official's stance.

In Korea, 'spoon class discourse' has attracted public attention in the press and among young people, which reflects that mass awareness that the class status structure is clearly rooted in the society becomes widespread. Although income distribution has been improved since late 2000s, it is interesting that Korean people's subjective perception concerning class mobility and social justice has been worsemed. By using the survey data on people's perception of opportunity inequality, this study finds that Korean people have by and large negative subjective awareness regarding socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts, and that the degree of the negative perception is greater in accordance with the people's subjective identification. The regression analysis reveals that the social status of respondents and their parents(-), experience of discrimination(+), age(-), and high education of college and above (+) have consistent effect over socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts with statistical significance. More concretely, as people have lower subjective status identification at the time of parent generation and their own generation, as they have the experience of discriminatory misconduct, and as they are young and highly educated, they have negative or pessimistic perception regarding opportuinity inequality. In addition, it is revealed that the unemployed and non-regular workers have significantly negative perception on socio-economic opportunity inequality, magnitude of opportunity inequality, while negative perception on the magnitude of opportunity inequality and achievement by efforts is noticeable among high and middle income households.

As the blind signature(10) does not reveal any information about the message or its signature it has been used for preventing the information leakage and for providing the anonymity in secure electronic payment systems. Unfortunately this perfect anonymity could be misused by criminals as blind signatures prevent linking the withdrawal of money nd the payment made 표 the same customer. Therefore we should provide publicly verifiable mechanism if it is required for the judge to trace the blackmailed messages. In this paper we propose a modified blind signature scheme which additionally provides the role of message recovery after analyzing the existing meta-ELGamal scheme(12) suggested by Horster. And we suggest a new fair blind multi-signature scheme based on the oblivious transfer protocol with which a judge can publicly verify its fairness and correctness if needed. Proposed scheme can also applicable to the diverse electronic payment applications.

Even ordinary-looking plays can have a profound meaning. Based on this assumption, Eugene Pink (1960) has established an analytical model of play with five elements, namely "delight", "meaning", "community", "rules" and "tools." It was an effort to reflect on the true meaning of play beyond the cortical entertaining nature of play. In this study, it was carried out that all the texts containing images and performance from the EBS character "Pengsu" were selected, since he emerged as a new star in 2019. And also his play structure was analyzed by applying the Pink's model. As a result, Pengsu's play structure was confirmed to be systematic and complete as a play prototype because it was well-organized with five elements of play. It was regarded as a successful character that skillfully attracts participants to the play world. Among the components of the play, "fun" was found to be his funny appearance, sudden and unconventional behavior, "meaning" was the elimination of authoritarianism, self-esteeming and energizing, "community" was a multi-platform media user who crossed off-on-line, analog-digital-line, "rules" was to set his concept fixed as a young stranger with an ego to unreveal his identity, and "tools" was shown as his character itself and continual discourse. It shows that until now, Pengsu has a social net function of quite spreading the positive meaning of encouragement and comfort, advice and guide, consideration and forgiveness, introspection and nirvana to all members of our society, including the youth who are struggling with uncertainty and anxiety by showing rather exaggerated and stimulating performance that precisely combines these play elements.
