This study aims to explore how to establish any foundation of the value of the unification of the Korean Peninsula in multicultural society of Korea. Its main issue is related to Korean identity of a nation and its shared value among the mulitcultural members, in particular, of North Koreans including defectors, foreign workers, and immigrants of international marriage and their children. For this study, I would utilize a given research of the application of two concepts of culture to multicultural levels by criticizing its limit; as an alternative, furthermore, I would pay attention to the possibility of the concept of emotion in multicultural members. A short feature in a given study of two conceptions of culture in a multicultural society is as follows: the first is to regard it as the patterns of meanings and symbols, which is very useful to understand others or other culture; secondly, to see it as the lasting process of perfection in human life, which makes us recognize ourselves as a member, so to speak, identity. In application it to Korean muliticultural members, however, there are crucial and complicated problems according to the cases of their lives. For North Koreans, firstly, they tend to get the conception of Korean identity in terms of ideological policies and education of North Korean government. This means that they have a strong hatred towards the word multiculture, in the level of recognizing the self-culture. Secondly, North Korean defectors also have the recognition of the self-culture, but their serious problem is discriminative treatments by South Korean in terms of socio-economics, in the process of their settlement. Thirdly, parents and their children in multicultural family can have their identity as Korean. In parents, however, the level is double that they can have both identities of Korean as well as of their countries. The foundation, therefore, of the value of the unification in the Korean Peninsula is closely related to the issue of identity as Korean. To recognize it, it is possible only to consider and reflect all members' lives by applying the dual conceptions of culture to their multicultural lives. That is not of outer system, but of inner, relational and cultural emotion, which enables them to share their common value of unification.

The purpose of this study is to analyze how the elements of activating happiness education suggested by Noddings is reflected in the Home Economics part of Middle School Technology-Home Economics Textbook Volume 1 of 2009 Curriculum Revision. The introduction style of unit, sub-unit, and small chapter, the objectives, the body contents, the activity resources, the tables/diagrams/pictures, the supplementry and advancedl materials, and the wrap-up and evaluation of sub-unit and units of Home Economics part of Technology Home Economics textbook volume 1 were analyzed. Noddings suggested the elements for activating happiness education in five areas of personal life sector including 'home making', 'place and nature', 'parenting', 'chracter and spiriual experiences', and 'growth of interpersonal relationships' and two areas of public one including 'preperation for work' and 'community, democracy and voluntary activities'. The specific elements in seven sectors of activating happiness education were extracted using the content analysis. How the elements of those suggested by Noddings were reflected in the various parts of the textbook were analyzed in terms of the closeness of approaches, contents, and procedures between Noddings's and textbook. The major findings of this study were as follows: 1. The degree to which the elements of activating happiness education were reflected in the textbook differed by each unit. The elements of activating happiness education were reflected the most frequently in the unit of 'Understanding Adolescence' and the least frequently in the unit of 'Self-management of Adolescence'. 2. Although the elements of activating happiness education were generally reflected in all the elements of a textbook, these elements were relatively more reflected in the body contents and tables/diagrams/pictures.

The purpose of this study is to investigate about security service history during the 1st and 2nd Republic. The 3rd Republic, one of the important periods, deserves special emphasis until now. But Compared with 1st and 2nd Republic, the 3rd Republic is inferior. Although security service history excluded the 1st and 2nd Republic. This research focused on the two points about the chief of the presidential security and the law of presidential security special order. Firstly, the chiefs of the presidential security in 1st Republic were Kim, Jang-Heung Seo, Jung-Hak Kim, Kuk-Jin Kwak, Young-Joo. Secondly, The law of presidential security special order be specified in Korean presidential security for the first time. Before the 1st Republic already recognized the importance of security services when they adopted the first security service regulations on December 29, 1949, which comprised 25 articles. But this law was only focused on presidential security and promulgated the law more than 10 years ago than law of the office of the Presidential Security in 1963. Deplorable in this law was declared by statute on July 7, 1953 from the 1st Republic, but repealed in 1960 after the 2nd Republic. Thirdly, 2nd Republic established the presidential security organization with the new government has been formed. In spite of this organization can not be kept for a long time, 2nd Republic attempted to professional forms of presidential security organization. The research of secret service history must continue to advance for academical learning.

Most brachytherapy treatment planning systems employ a dosimetry formalism based on the AAPM TG-43 report which does not appropriately consider tissue heterogeneity. In this study we aimed to set up a simple Monte Carlo-based intracavitary high-dose-rate brachytherapy (IC-HDRB) plan verification platform, focusing particularly on the robustness of the direct Monte Carlo dose calculation using material and density information derived from CT images. CT images of slab phantoms and a uterine cervical cancer patient were used for brachytherapy plans based on the Plato (Nucletron, Netherlands) brachytherapy planning system. Monte Carlo simulations were implemented using the parameters from the Plato system and compared with the EBT film dosimetry and conventional dose computations. EGSnrc based DOSXYZnrc code was used for Monte Carlo simulations. Each $^{192}Ir$ source of the afterloader was approximately modeled as a parallel-piped shape inside the converted CT data set whose voxel size was $2{\times}2{\times}2\;mm^3$. Bracytherapy dose calculations based on the TG-43 showed good agreement with the Monte Carlo results in a homogeneous media whose density was close to water, but there were significant errors in high-density materials. For a patient case, A and B point dose differences were less than 3%, while the mean dose discrepancy was as much as 5%. Conventional dose computation methods might underdose the targets by not accounting for the effects of high-density materials. The proposed platform was shown to be feasible and to have good dose calculation accuracy. One should be careful when confirming the plan using a conventional brachytherapy dose computation method, and moreover, an independent dose verification system as developed in this study might be helpful.

With the recent prevalence of helical CT and multi-slice CT, which deliver higher radiation dose than conventional CT due to overbeaming effect in X-ray exposure and interpolation technique in image reconstruction. Although multi-detector and helical CT scanner provide a variety of opportunities for patient dose reduction, the potential risk for high radiation levels in CT examination can't be overemphasized in spite of acquiring more diagnostic information. So much more concerns is necessary about dose characteristics of CT scanner, especially dose efficient design as well as dose modulation software, because dose efficiency built into the scanner's design is probably the most important aspect of successful low dose clinical performance. This study was conducted to evaluate z-axis geometric dose efficiency in single detector CT and each level multi-detector CT, as well as to compare z-axis dose efficiency with change of technical scan parameters such as focal spot size of tube, beam collimation, detector combination, scan mode, pitch size, slice width and interval. The results obtained were as follows ; 1. SDCT was most highest and 4 MDCT was most lowest in z-axis geometric dose efficiency among SDCT, 4, 8, 16, 64 slice MDCT made by GE manufacture. 2. Small focal spot was 0.67-13.62% higher than large focal spot in z-axis geometric dose efficiency at MDCT. 3. Large beam collimation was 3.13-51.52% higher than small beam collimation in z-axis geometric dose efficiency at MDCT. 4. Z-axis geometric dose efficiency was same at 4 slice MDCT in all condition and 8 slice MDCT of large beam collimation with change of detector combination, but was changed irregularly at 8 slice MDCT of small beam collimation and 16 slice MDCT in all condition with change of detector combination. 5. There was no significant difference for z-axis geometric dose efficiency between conventional scan and helical scan, and with change of pitch factor, as well as change of slice width or interval for image reconstruction. As a conclusion, for reduction of patient radiation dose delivered from CT examination we are particularly concerned with dose efficiency of equipment and have to select proper scanning parameters which increase z-axis geometric dose efficiency within the range of preserving optimum clinical information in MDCT examination.

The work appeared a featured female character in the Disney animation film begins with 'Snow White' released in 1937. After then, the 11 female characters appeared included 'Tangled' in 2010. Female characters reveal their identity due to obedient, family-oriented and marriage with prince and then gradually develop to heroine who leads to man, and is independent, pioneering, and sometimes saves the nation. Nevertheless, the ending of the Disney animation was still not escape the institutional, traditional discourse. Female characters are followed to meet the featured actor kissing and marriage, or was to show the virtues of sacrifice for the actor. However, Elsa in 'Frozen' is the character with an independent identity compared with the patriarchy, male chauvinism and heterosexual dichotomous discourse given so far in Disney. In this study, it is to explain the change of gender identity in the character of Elsa through Queer theory that deconstructs the distinction between sex and gender, and is constituted by the actions typed and performed the gender concept, and is dismantling the dichotomy itself such as male/female, heterosexual/homosexual. The performative of Queer make the boundaries between lesbian-gay, sexuality and heterosexual ambiguous. It can be said that the performative has political nature resisted to the dominant discourse through these parodiable strategy. The performative showed of Elsa is in the boundaries between the sisterhood and the heterosexual. When analyzed in a heterosexual perspective Elsa's identity is to be understood as simply just love the intimacy of a sister and a sister. On the other hand, if you focused on the relationship between women and the relationship between Elsa and Anna is recognized as the point of view of homosexuality. Because if you look at the concept of lesbian continuum, the homosexual love in the female characters of Disney seems like a bond between women, easier than heterosexual love can be hidden sexual desires. Elsa has developed into a performative identity through the expression of performative and the inhibitory of queer identity. And then the her sorcery that was initially contraindicated and the presence of a fear became to the 'lesbian phallus'. The sorcery that can be seen the signifying phallus against to the privileges of heterosexual patriarchy is recognized in the world of Arendal. Elsa is a new women featuring Disney characters. as this character is analysised by Queer theory, this study seeks to expand the area of the various character analysis methods.

Purpose: To compare the mid-term follow-up results of anterior cruciate ligament(ACL) reconstruction with the bone-patellar tendon- bone(BTB) autograft to those with the BTB allograft. Materials and Methods: Retrospective study was performed in 59 cases with BTB autograft and 42 cases with BTB allograft. Evaluations include Lysholm score, 2000 IKDC subjective knee score, Shelbourne patello-femoral pain score , Lachman test, pivot shift test, KT-1000 arthrometer test and 2000 IKDC knee examination. Results: There were no significant statistic differences between two groups in Lysholm score and 2000 IKDC subjective knee score of more than 70 (p<0.05). Five cases(8.5%) showed the patello-femoral pain score less than 80 according to Shelboume with autograft group and two cases(4.8%) with allograft group (p<0.05). Lachman test, pivot shift test and KT-1000 arthrometer test showed no significant statistic differences between two groups(P<0.05). Fifty-four cases(91.5%) were normal or nearly normal according to the 2000 IKDC knee examination with autograft group and thirty-eight cases(90.4%) with allograft group(p<0.05).Conclusion: BTB allograft as well as BTB autograft is considered to be an acceptable choice for ACL reconstruction.

The purpose of this research is to develop a detection model for companies designated as administrative issue in KOSDAQ market using financial data. Administration issue designates the companies with high potential for delisting, which gives them time to overcome the reasons for the delisting under certain restrictions of the Korean stock market. It acts as an alarm to inform investors and market participants of which companies are likely to be delisted and warns them to make safe investments. Despite this importance, there are relatively few studies on administration issues prediction model in comparison with the lots of studies on bankruptcy prediction model. Therefore, this study develops and verifies the detection model of the companies designated as administrative issue using financial data of KOSDAQ companies. In this study, logistic regression and decision tree are proposed as the data mining models for detecting administrative issues. According to the results of the analysis, the logistic regression model predicted the companies designated as administrative issue using three variables - ROE(Earnings before tax), Cash flows/Shareholder's equity, and Asset turnover ratio, and its overall accuracy was 86% for the validation dataset. The decision tree (Classification and Regression Trees, CART) model applied the classification rules using Cash flows/Total assets and ROA(Net income), and the overall accuracy reached 87%. Implications of the financial indictors selected in our logistic regression and decision tree models are as follows. First, ROE(Earnings before tax) in the logistic detection model shows the profit and loss of the business segment that will continue without including the revenue and expenses of the discontinued business. Therefore, the weakening of the variable means that the competitiveness of the core business is weakened. If a large part of the profits is generated from one-off profit, it is very likely that the deterioration of business management is further intensified. As the ROE of a KOSDAQ company decreases significantly, it is highly likely that the company can be delisted. Second, cash flows to shareholder's equity represents that the firm's ability to generate cash flow under the condition that the financial condition of the subsidiary company is excluded. In other words, the weakening of the management capacity of the parent company, excluding the subsidiary's competence, can be a main reason for the increase of the possibility of administrative issue designation. Third, low asset turnover ratio means that current assets and non-current assets are ineffectively used by corporation, or that asset investment by corporation is excessive. If the asset turnover ratio of a KOSDAQ-listed company decreases, it is necessary to examine in detail corporate activities from various perspectives such as weakening sales or increasing or decreasing inventories of company. Cash flow / total assets, a variable selected by the decision tree detection model, is a key indicator of the company's cash condition and its ability to generate cash from operating activities. Cash flow indicates whether a firm can perform its main activities(maintaining its operating ability, repaying debts, paying dividends and making new investments) without relying on external financial resources. Therefore, if the index of the variable is negative(-), it indicates the possibility that a company has serious problems in business activities. If the cash flow from operating activities of a specific company is smaller than the net profit, it means that the net profit has not been cashed, indicating that there is a serious problem in managing the trade receivables and inventory assets of the company. Therefore, it can be understood that as the cash flows / total assets decrease, the probability of administrative issue designation and the probability of delisting are increased. In summary, the logistic regression-based detection model in this study was found to be affected by the company's financial activities including ROE(Earnings before tax). However, decision tree-based detection model predicts the designation based on the cash flows of the company.

As a previous study to investigate recognition gap of creativity between Korea and America, this study has examined Korean university students' implicit creativity toward Korea and America. The research method using in this study was as follows: The subject were university students in Korea, and they were asked to answer multiply for open-ended questions. For the analysis of the answers, a frequency analysis was used. The results were as follows: 1) It showed that Korean university students considered creativity trait as cognitive trait, personality, cultural trait, research and development areas and arts areas. This result means that Korean university students tend to recognize creativity similarly to the ways of established theories of creativity. 2) For the case of Korea, environmental trait like sociocultural background had great importance for all cases of creativity trait and non-creativity trait. 3) American creativity was recognized focused on individual tendency, on the while, community spirit was considered as creativity trait in Korean creativity. 4) It is considered that American culture had better condition for displaying creativity than Korean culture. 5) Traditional culture of Korea was recognized as creativity trait in terms of originality and superiority, and the possibility of modernistic use of Korean culture. 6) Creative people were ranked by artists, executives, rulers and scientists who were well-known to Korean university students. 7) In the comparison of creativity trait between the two countries revealed the traits of creative people, American creativity was reflected more than Korean creativity, This result seems that those people were favored by Korean university students who were familiar with American culture. In conclusion, this study has found another possibility of creativity of the East among cross-cultural creativity studies. Moreover, this study has suggested that traditional culture and tradition renewal, and values of the East are superior cultural resources which are not exist in the West, and those are expected to play a role in developing creativity.

This paper describes a study on the permeability reduction of the riverbed ground during urban railway tunnel construction. The research is mainly concentrated on the study of the grouting or injection methods among permeability reduction methods which can be adapted in the riverbed ground. Firstly, the various grouting methods are theoretically reviewed and compared based on the previous research papers and case study results. It is also evaluated the grouting methods in view of a safe construction of the river crossing railway tunnel. Baced on the literature review and previous construction data, the design technology of grouting methods considering the long term hydro-geological behaviour in the riverbed, is suggested. Two injection methods namely, Natural Durable Stabilizer(N.D.S) and Space-Multi Injaction Grouting(S.M.I) methods, are introduced as new approach methods which can be adopted to modify the riverbed ground. In order to evaluate the ground that grouted and modified by the N.D.S and S.M.I method, the pilot test programmes including the field and laboratory permeability tests, are carried out in the river crossing tunnel construction sites. The results obtained from pilot test programme, are also reviewed. In conclusion, the grouting efficiency of the S.M.I method using the non-alcalimeter silica sol is better than that of NDS method using cement. In addition, it hopes that the research results are contributed to develop the grouting design technology.
