Since the decommissioning of nuclear plants and facilities, large quantities of slightly contaminated concrete waste have been generated. In Korea, the decontamination and decommissioning of the KRR-1, 2 at the KAERI have been under way. And concrete waste was generated about 800 drums of 200 L. The conditioning of concrete waste is needed for final disposal. The concrete waste is conditioned as follows: mortar using coarse and fine aggregates is filled void space after concrete rubble pre-placement into 200 L drum. Thus, this research has developed an optimizing mixing ratio of concrete waste, water, and cement and has evaluated characteristics of a cement waste form to meet the requirements specified in disposal site specific waste acceptance criteria. The results obtained from compressive strength test, leaching test, thermal cycling test of cement waste forms conclude that the concrete waste, water, and cement have been suggested to have 75:15:10wt% as the optimized mixing ratio. Also, the compressive strength of cement waste form was satisfied that including fine powder up to maximum 40wt% in concrete debris wastes about 75%. As a result of scale-up test, the mixture of concrete waste, water, and cement is 75:10:15wt% meet the satisfied compressive strength because the free water increased with and increased in particle size.

The purpose of this study is to propose an effective class of College English, one of the essential liberal arts subjects of S University, and to analyze the learning effect. This subject targets students with different majors in the first grade, and the learning goal is to improve their reading skills by analyzing students' English skills, especially sentences, as grammatical elements in everyday situations. This thesis examines how College English classes can be conducted in the form of convergence class in the COVID-19 era to induce students' learning motivation and create learning effects. The form of this convergence class is as follows. First, lecture videos, second, Webex real-time non-face-to-face classes, and third, face-to-face classes. In this study, the class procedure of the first class among the classes that were actually conducted during the semester was presented as an example. The researcher specifically surveyed the pre-class questionnaire and conducted the class by grasping the students' English skills and characteristics of the learners through the results. And after taking the course, the questionnaire was surveyed into 30 items and the results were analyzed. Specifically, the results of satisfaction with the composition of the lecture, satisfaction with the lecture video, satisfaction with the face-to-face class, interaction with students, and learning effects were analyzed. This class proposal is a learner-centered model in the form of convergence.

Objective : By examining EEG status in Korean Traditional Medicine (KTM) from the viewpoint of 'form-qi theory(形氣論)', We wish to prepare for the fundamentals of applicability of KTM diagnoses to EEG. In addition, through reinterpretation of existing Western Medicine reports from the viewpoint of KTM, We tried to find out interrelationship between them. Method : In this paper, a methodology applicable to KTM diagnoses of EEG is presented from the EEG features in waveform characteristics, personalized diversity, and cognitive activity reflection. Results : Frequency bands are assigned to corresponding one of the eight trigrams in terms of yin/yang balance, which is analogous with EEG spectrum analysis mostly used in EEG quantification. The amplitude ratio of each EEG for each frequency band gives meaningful index numbers which can be used in EEG data interpretation, and every index number is named after the sixty four hexagrams. These approaches are adopted through both '4-band classification system and '6-band classification system', and applied to pre-existing reported EEG data obtained from normal adults. These analyses show that changes and distribution pattern in the index numbers are observed as a whole on both left-right line and front-back line connecting EEG measurement cephalic electrodes. And differences in distribution pattern of three index numbers deduced from '6-band classification system' are discussed according to constitution. Conclusion : The index numbers introduced here, which are the spectral power ratio for each EEG, are based on KTM yin/yang balance. These index numbers vary according to cephalic location, so its application in terms of traditional meridian theory is strongly expected. The index number distribution also shows different patterns according to constitution.

The purpose of this research is to find out the characteristics of sexuality expressed in the contemporary modern fashion jacket, especially designer Thom Browne. Thom Browne is a very successful fashion brand that has focused on design of extraordinary theme. In the research methodology, the analysis was carried out over a total of 862 work pieces in the collection of S/S, F/W, RESORT, PRE-FALL from 2010 to 2016. The characteristics of the contemporary expressions of sexualities can be subdivided into four separate categories. First, The demolition is inflated retail, exaggerated shoulder silhouettes, such as short sleeve jacket is mainly used in the form of a women's match with each other and expressed by different materials applied to men. Female jackets are designed for the silhouette to highlight the strong masculine image to highlight additional detail on the chest or vice versa, to express women's jacket to distort the female. Secondly, Sensuality is designed the body of a male was represented by a design that gives a greater masculinity was expressed that the interpretation of the male gender in detail jacket sleeves and wrap the exposed areas of the important men of fashion. Women's jacket by using a see-through material, mainly sensory Castle outward to reveal the concealed body of the female form a natural curve shows the feminine sensuality. Lastly, Incongruity is inadequate representation by sex of clothing to match the jacket and skirt in women's wear it is also unsuitable for revealing gender as male by applying soot forms. The study attempts to find the meaning in that this presents the direction of the creative development of the modern fashion design based on the aesthetic characteristics of Thom Browne fashion appearing in the modern fashion.

Through this thesis, I intended to analyze Hollywood animation through that achieved in box office by directing viewpoint. of Chris Sanders and Dean Deblois not only shows standard narrative structure of adventure, comedy, fantasy, but also express message of story and thorough visual. Analysis of directing classify contents and form. In contents, constitution of narrative and set up of character, irony of plot, characterization and popularity are embossed. In form, lighting and special effect, design and layout, 3D technology and stereoscopic camera technique based on the capital strength are outstanding. The high evaluation for film is possessed of box offic, remained within value and popularity, and delivered metaphysical theme without repulsion. The director's direction make success even if the pre-production manage by huge system approach.

Background: Prisoners represent a population group that is disadvantaged, socially deprived and underprivileged, needing particular attention with regard to provision of necessary oral health care, health promotion and motivation and tobacco cessation. Considering the situation in prisons, smoking and tobacco chewing are burning issues related to health deterioration and economic loss that seem to be overlooked by the public health sectors. Aim: To assess prisoners' perception of tobacco use and cessation in Chhatisgarh, India. Materials and Methods: A pre-tested, close ended questionnaire was administered in the form of extensive face to face interviews, to assess perceptions regarding tobacco use and cessation in the central jail of Durg District of Chhattisgarh state, India. Results: Prevalence of tobacco usage amongst the prisoners was found to be 61%. Some 27% reported smoking, 44% used tobacco in the chewable form and 29% indulged in consuming tobacco in both forms i.e. smoked as well as chewed. Results suggest several recommendations for policy relevance such as provision of a prison dentist, a tobacco cessation counseling program and targeted eradication of oral cancer by educating the prisoners. Conclusions: Health is a fundamental human "right of everyone to the enjoyment of the highest attainable standard of physical and mental well-being". This applies to prisoners just as it does to every other human being. The alarming findings in the study suggest the need for dental treatment facilities and tobacco cessation counseling in prisons.

The purpose of this study was to conduct a dynamic analysis of married women's return to the workforce following first childbirth. We have based our investigation on the data compiled by the KLIPS, where the workforce performance is the focal point of it's research, and by these materials, this study has analyzed the aspects of the factors that decide post-childbirth return to the workforce. We have applied the Cox Regression Hazard Model, where corroborative evidence are statistically applied. The following are the conclusions that were derived from this research: First, according to the study, academic background is a vital factor in reducing the gap and time of women's return to the workforce. Second, whether having active child-care after giving birth or not doubles the chances of women returning to the workforce. Third, if the pre-birth employment form was a wage-work and the rate of returning to the workforce was lower than the non-wage, relatively speaking, this reflects that the non-wage form of work, which provides a better possibility to return to the workforce after giving birth, could be another way to prevent women's career discontinuation.

We propose a group-based security scheme for hierarchical wireless sensor networks. We model the network for secure routing with 3-tier sensor network comprised of three types of nodes: Base Station, Group Dominator and ordinary Sensor Nodes. Group-based deployment is performed using Gaussian (normal) distribution and show that more than 85% network connectivity can be achieved with the proposed model. The small groups with pre-shared secrets form the secure groups where group dominators form the backbone of the entire network. The scheme is devised for dealing with sensory data aggregated by groups of collocated sensors; i.e., local sensed data are collected by the dominating nodes and sent an aggregated packet to the base station via other group dominators. The scheme is shown to be light-weight, and it offers a stronger defense against node capture attacks. Analysis and simulation results are presented to defend our proposal. Analysis shows that robustness can significantly be improved by increasing the deployment density using both the dominating and/or ordinary sensor nodes.

The consumer affair is one of the rapidly evolving problems in the process of recent economic growth. As the society and its economy changes, the nature and the scope of the consumer affairs also changes. while the main concept of the consumer affaires originated from the market mechanism, it is now expanding beyond the market mechanism to include everyday lives of consumers. In solving the problems which arise form the status difference between the manufacturer and the consumer the manufacturer's action is no less important the consumer's self-improvement of its status. The manufactures with the purpose of getting maximum profits from the consumers are conducting the consumer oriented managerial marketing, but this sis done form the manufacturer's point of view with the consumer's position being neglected. It is the purpose of this paper to investigate the nature and direction of the marketing from the consumer's position being neglected. It is the purpose of this paper to investigate the nature and direction of the marketing from the consumer's point of view. For this study a couple of pre-investigations were done. First, I surveyed the changing consumers with economic growth the developing process of marketing, and the cause and characteristics of the today's consumer affaires. Second, I studied the concept change of the modern marketing, and the concept of the consumerism which was materialized by this concept change. I further studied, with the consumer's point of view, the socioecological marketing which is based on the consumerism. The conclusion of this investigation is that the manufacturers should convert the in humanized marketing to the more human and environment conscious socioecological marketing because the consumer affairs which arise from the mass consumption of the modern days are expanding to include everyday's problems. This conversion naturally should be based on the human concept based consumerism. To be more effective, the manufactures should assume more social responsibilities and conduct the socioecological marketing voluntarily and willingly.

Purpose: The aim of the study was to develop the Korean version of the Working Alliance Inventory (KWAI) and to assess reproducibility of both its therapist and client forms. Methods: The 12-item WAI was translated into Korean. The translation procedure followed the guidelines proposed by Beaton et al. (2000). Development of KWAI involved its translation, back-translation, and pilot testing of the pre-final version to establish Korean cultural adaptation of the original version of WAI. For test-retest reliability, therapists (N=30) and clients (N=47) completed the questionnaire on two different occasions. The interval between occasions was two to seven days, depending on subject availability. Data were collected from clinicians working in general hospitals and private clinics, and clients who had received treatment within three months. The intra-class correlation (ICC ($_{2.1}$)) was calculated for assessment of the reproducibility of the translated questionnaire. Results: The test-retest ICC ($_{2.1}$) of the client form and the therapist form was 0.92 (95%CI:0.86-0.95) and 0.94 (95%CI:0.89-0.97), respectively. Answers to items 2, 8, and 11 showed a tendency to be omitted due to ambiguity of meaning in Korean. Idiomatic expression was employed rather than word-to-word translation to have clear meaning of those items. Conclusion: The KWAI was successfully translated and adapted for applications to Korean clients and therapists, with a satisfactory level of reliability. Therefore, it can be suggested that the KWAI is useful in providing a reliable assessment of working alliance between therapists and clients.
