Purpose. The purpose of this study was to identify the stage of change of smoking cessation behavior and investigate factors associated with the stage of smoking cessation behavior according to the transtheoretical model. Methods. The participants, 297 smokers & quitters were selected by a stratified random sampling from 127 high school sophomore students in B city. Data were collected from April 6th to 16th, in 2002 using the structured self-report questionnaire. Results. The subjects were distributed in each stage of change of smoking cessation behavior: there were 46 subjects (15.5%) in precontemplation, 73 subjects (24.6%) in contemplation, 67 subjects(22.3%) in preparation, 56 subjects (18.5%) in action, 55 subjects (18.5%) in maintenance. Compared to the precontemplation and contemplation, people in preparation tended to smoke daily more and smoked for a shorter time, and as precontemplation progressed to the maintenance, past 1 year smoking cessation frequency increased and friends smoking decreased. Smoking onset age was the earliest in preparation, and the latest in maintenance. Helping relationships and self relationships are used a lot in precontemplation and also in contemplation. In preparation, self liberation and helping relationships are used a lot, in action, self liberation and helping relationships, and in maintenance, self liberation and environmental reevaluation. At each stage, the score of negative affect situation was the highest, but the one of negative affect situation, positive social situation, habitual strength, weight control decreased as precontemplation progressed to the maintenance. While the score of social pros and coping pros decreased with increasing stage, the one of cons tended to increase. Through stepwise discriminant analysis, it was found that social pros, smoking onset age, delf-libration were the most influencing powers among factors associated with the stages of smoking cessation behavior. Conclusions. This study suggested that, in developing an effective smoking cessation intervention for adolescents, all the stage of a client's cessation had to be assessed prior to applying intervention programs. In addition, the results of this study will become a pillar of smoking cessation program planning and application.

The purpose of this study is to analyze the 'Scenery of the Urban Residence' represented in Korean films of the liberation period. It is assumed that public films reflect the human activities, residential culture and cityscape of those days. For the analysis, a pool of 7 Korean films from 1946 till 1949 was constructed. In these films, the sceneries of the urban life were represented as the following: 1) The western-style architectural spaces, such as cultural residence and apartment were emphasized to reflect the longing and curiosity of the general public for modern culture and lifestyle. 2) The cityscape including a narrow alley, crossroads and modern buildings was intentionally represented to express visually the city of Seoul under the slow wave of modernization.

Physical property changes of printed circuit board (PCB) according to heat treatment conditions were investigated. The heat treatment was carried out in air and nitrogen atmosphere at temperature range from $200^{\circ}C$ to $325^{\circ}C$. Thermogravimetric analysis showed that the PCB was pyrolyzed in two steps. The thickness of PCB expanded by 11~28% at about $300^{\circ}C$ in both air and nitrogen atmosphere as layer disintegration occurred. Mechanical strength of PCB decreased from 338.4 MPa to 20.3~40.2 MPa due to the delamination caused by the heat treatment. The heated printed circuit boards were crushed and sieved for analysis of density distribution and liberation degree of copper according to particle size. As a result of the density distribution measurement, non metallic particles and copper particles were concentrated into different size range, respectively. The liberation degree of copper was improved from 9.3% to 100% at size range of $1,400{\sim}2,000{\mu}m$ by heat treatment.

YBa2Cu3O7-$\delta$, Y2BaCuO5, and binary compounds in the Ba-Cu-O system with the nominal composition of Ba2CuO3, BaCuO2, Ba3Cu4O7, Ba3Cu5O8 were synthesized to investigate the heat evolutions and crystalline phases in the hydration reaction of orthorhombic YBa2Cu3O7-$\delta$ phase. The observed crystalline phases were YBa2Cu3O7-$\delta$, Y2BaCuO5, and BaCuO2, or Ba2Cu3O5＋x, and some amount of noncrystalline phase in the Ba-Cu system comounds. In contact with distilled water, YBa2Cu3O7-$\delta$ and Y2BaCuO5 did not have considerable heat liberation, but in the binary compounds of the Ba-Cu-O system, the amount of total heat liberation was increased with respect to the Cu content. It might be that the reaction of high temperature superconductor YBa2Cu3O7-$\delta$ with water and/or moisture originated from the unusual oxidation state of Cu ion and the presence of amorphous Ba-Cu oxide compound. The degradation of high Tc superconductor by moisture and water could be controlled by restricting the heterogeneous distribution of Tc comlposition and the formation of second phase, such as stable Y2BaCuO5, and the resulting unstable Ba-Cu oxide compound.

Aim: Connexin 43 (Cx43) and E-cadherin are important biomarkers related with cancer. Their expression at protein and mRNA levels was here investigated in 50 primary lung carcinoma tissues and 20 samples of adjacent normal tissue of Chinese patients with non-small cell lung cancer (NSCLC). Methods: Protein and mRNA expression were evaluated by ABC immunohistochemistry and RT-PCR. Results: (1) The positive expression rates of Cx43 and E-cadherin protein were higher in the adjacent normal tissues than those in the primary lung carcinoma tissues; (2) the positive expression rates of Cx43 and E-cadherin protein decreased with NSCLC progression; (3) the expression of E-cadherin protein was not related with the pathological type of NSCLC; and (4) the relative quantity of the Cx43 or E-cadherin mRNA expression was correlated with the the histological type, clinical stage, cancer cell differentiation and the lymph node metastasis. Conclusion: The data suggested that the Cx43 and E-cadherin are reduced with NSCLC progression, and might be important biomarkers for judging the metastasis and prognosis.

Recently, a lot of articles and writings defending animal right and welfare are introduced into our society. For example, P. Singer's Animal Liberation, T. Regan's The Case for Animal Rights, and J. Rachels's Created From Animal are representative writings of animal ethics. In his books, P. Singer maintains that all animals are equal. T. Regan insisted that animals as a subject of a life have rights. J. Rachels's moral individualism is that how an individual may be treated is to be determined, not by considering his group membership, but by considering his own particular characteristics. Interestingly, they use common argument called 'argument from marginal cases' to justify their theoretical positions. If we can disclose the weakness of the argument, all kinds of animal ethics which defend animal right and welfare such as animal liberation theory, animal rights theory and moral individualism will collapse. In this paper, I will examine the concrete contexts in which Singer, Regan and Rachels make use of the argument. And I will critically examine the argument. Lastly I will show that the attempt to deny the difference of species is unsuccessful.

Purpose : This study suggests that the unique chakra arrangement of Tibetan singing bowls resembles the mantra of chakra lotus in the tantric tradition and the structure of chakra ascent, The two aim at the liberation of consciousness and confirm that they have a body, mind, and conscious healing mechanism. Methods : First, the structural characteristics of Tibetan singing bowls arrangement and chakra lotus mantra arrangement were investigated through the consideration of previous studies. Next, the healing mechanism of Tibetan singing bowls, which has been learned in Nepal, was examined through previous studies and literature to clarify that the rise of chakra in the two systems has a balance of body, mind, and consciousness and aims at liberation of consciousness. Results : The arrangement of Tibetan chakras is similar to the mantra of chakra lotus. Both have a structure in which the auxiliary sound of the previous chakra is interlocked with the structure of being the main sound of the next chakra to raise the chakra. At this time, the rise of the chakra is the liberation of consciousness by the ultimate purpose. Conclusion : Tibetan chakra are structurally similar to chakra lotus mantras and chakra ascents, as they have a theoretical background to tantric traditions. Chakra is the quality of inner consciousness that is conveyed to the outside and expressed in its own actions. Therefore, chakras should be well coordinated to lead our lives healthily. In this point, the chakra arrangement of Tibetan singing bowls is a system that exposes the inner balance to the outside and heals us more directly. Therefore, Tibetan singing bowls therapy has an integrated medical value in restoring our mind and body balance. Because chakras are dimensions of consciousness, the study of chakras is abstract or lacking, so more systematic and scientific study of chakras is needed.

This thesis proposes to explore the theatre aesthetics of North-Korea during after the Liberation. From now South-Korean theorists have provided the theatre aesthetics of North-Korea to South-Korea, so we can say that it lacks of an equity. For example, South-theorists have said that North-Korean theatre only emphasized politics and propaganda, they have had not any aesthetics in performance. So this study focused on North-Korean critics and records for fairness and as a result something new is founded. The best theatres in North-Korea were some works which contains natural and proper lines to character, well-expressed inner desires of characters, realistic acting and stage design, and realistic life of working class. Of course they should reflect communist ideology and policy, but more important is that it did not mean everything in North-Korea. So we can say that it is fact that North-Korea should reflect their policy, which does not mean lack of aesthetics of performance. North-Korea had an obvious point of view for theatre, and they made an effort to realistic lines, movements and stage. During right after the Liberation, North Korea sought to find an answer for 'realization of true life', and sought to eliminate Japanese acting style in theatre. Concluded theatre aesthetics of North-Korea during right after the Liberation is realistic acting and directing style.

HDD-based RAIDs have been used in high-capacity storage systems for traditional data server. However, their data reliability are relatively low and they consume lots of power since hard disk drive is weak on shock and its power consumption is high due to frequent spindle motor operation. Therefore, this paper presents new SSD based RAID system architecture using various erasure codes. The proposed methode applys Reed-Solomon, EVENODD, and Liberation coding schemes onto file system level and device driver level, respectively. Besides, it uses data allocation method to minimize the side effect of reducing the lifespan of SSD. Detail experimental results show that Liberation code increase wear-leveling rates of SSD based RAID-6 more than other codes. The SSD based RAID system applying erasure codes at the device driver level shows better performance than that at the file system level. I/O performance of RAID-6 system using SSD is 4.5%~8.5% higher than that of using HDD and the power consumption of the RAID system using SSD is 18%~40% less than that of using HDD.
