  • The cultivated radish (Raphanus sativus L.) is a major vegetable crop in the world wide and fast-growing species that grows inhabitats of six continents. It is very important to determine hybrid seed purity in the production of hybrid Brassica vegetable seeds to avoid unacceptable contamination with self-inbred (sib) seeds. The use of random amplified polymorphic DNA (RAPD) markers for evaluating seed purity in $F_2$-hybrid radish cultivars demonstrated. One hundred eighty seeds from the F1 male and female harvest were subsequently screened for seed purity using 13 primers. The 13 primers result in 17 cultivar-specific bands and 23 variable RAPD bands scored for cultivar. RAPD analysis of hybrid seeds from the harvest revealed 128 seeds tested except underdevelopment and decayed seeds were sibs. Especially, $F_2$ hybrids of radish, OPC13, OPD20 were presented clear hybrid bands. It maintains higher than average level of genetic diversity compared with their correspondent parents. RAPD amplification of DNA extracted from germinated individuals from the female harvest reveal that 10 of 208 seeds tested were self-inbred (4.8%). RAPD analysis of hybrid seeds from the male harvest revealed 7 of the 208 seeds tested were sibs (3.4%). The RAPD may lead to a better insight in to the hybrid seed purity.

  • This thesis attempts to describe the basis and value system respectively selected by opinions pro and against bio engineering technology and to induce discussions on the basis of the concept called 'two culture' issue by C. P. Snow - science culture, human culture, a teleological ethical theory and a deontological ethical theory, traditional eugenics, and liberalism eugenics. In addition, it will discuss about inconvenient truth about science and bio engineering which we have wrongly understood up to now - a myth on objectivity of science, autonomy of science and a scientist, a hunger of world, science expected to be responsible for all men. Lastly, it will describe study ethics and social responsibility, openness, moral imagination, self-examination, character of a bio engineer as professionalism.

  • As architecture has a role of vessel that contains human life, architecture of museums in a region must be a vessel that contains identity of the region. Jeju Province possesses excellent natural landscape acknowledged by the world. As such, architectural design of museums in Jeju region, differentiated in terms of natural, humanistic and cultural characteristics from other regions, must include identity of Jeju. Jeju has established and is operating so many museums with different themes that it is referred to as the heaven of museums. In addition, museums as cultural facilities must be the measure of cultural level representing regional identity and perform the role of advance guard that leads architectural culture of the region. Also, such excellent architectural asset is an important landscape element that increases value of the region. Based on Landscape Management Guideline established in 2009 by Jeju Special Self-governing Province under such critical mind, this study will support design problems and improvements of museums through case study and analysis on design characteristics of national and private museums in Jeju. Accordingly, the purpose of this study is to provide basic data to be pursued by future museums that contain identity of Jeju, based upon the results of analysis described above.

  • Target tracking in a real world situation is difficult problem because of continuous variations in images, huge amounts of data, and high processing speed demands. The problem becomes even harder in the case of sea background. This paper presents an initial study of neural network based method for target detection and tracking in cluttering environment. The approach uses a combination of differential motion analysis, Kohonen self-organizing network and region growing method. The network is capable of detecting the mass-centers of moving objects within one frame. The history of neurons positions in the sequential frames approximates the traces of the targets. The experiments done with the network in simulated environment showed promising results.

  • The purpose of this study was to examine the moderating effects of mother-adolescent communication time on the relationship between maternal meta-emotion philosophy, adolescent psychological adjustment and depression. The participants for this study comprised 181 first and second grade high school students and their mothers, residing in Seoul. The results of the analyses indicated that, (a) maternal disapproving is negatively correlated to adolescents' positive world views, and that maternal laissez-faire is also negatively correlated to adolescents' emotional responsiveness. However, a positive correlation is revealed between maternal emotion-coaching and adolescents' positive self-esteem. (b) It is evident that adolescents' emotional responsiveness is influenced by maternal laissez-faire, and that adolescents' positive self-esteem is influenced by emotion-coaching. It also indicated that mother-adolescent communication time is influenced by dismissing as well as laissez-faire meta-emotion philosophy. (c) It revealed that mother-adolescent communication time, in part, has a meaningful moderating effect on the relationship between meta-emotion philosophy and adolescent depression. Therefore, the present study indicates that even if maternal disapproving, laissez-faire, or dismissing is practiced, adolescent depression levels decrease as mother-adolescent time lengthens.

  • Head and neck squamous cell carcinoma (HNSCC) is one of the world top ten most common cancers with its highest occurrence in the Indian subcontinent and different aggressive and etiological behavioural patterns. The scenario is only getting worst with the 5 year survival rates dropping to 50%, persistent treatment failures and frequent cases of relapse/recurrence. One of the major reasons for these failures is the presence of cancer stem cells (CSCs), a small population of cancer cells that are highly tumourigenic, capable of self-renewal and have the ability to differentiate into cells that constitute the bulk of tumours. Notably, recent evidence suggests that cancer stem cells are especially resistant to conventional therapy and are the "drivers" of local recurrence and metastatic spread. Specific markers for this population have been investigated in HNSCC in the hope of developing a deeper understanding of their role in oral cancer pathogenesis, elucidating novel biomarkers for early diagnosis and newer therapeutic strategies. This review covers the fundamental relevance of almost all the CSC biomarkers established to date with a special emphasis on their impact in the process of oral tumourigenesis and their potential role in improving the diagnosis, prognosis and treatment of OSCC patients.

  • Purpose: Lung cancer patients are often stigmatized since lung cancer is closely associated with smoking, which is a self-administered life style. The stigma of lung cancer has been examined in some qualitative studies; however, their findings were diverse and not yet synthesized. Therefore, this meta-synthesis study aimed to explore how lung cancer patients experience stigma. Methods: A meta-synthesis method, as suggested by Sandelowski and Barroso in 2007, was applied by aggregating the findings after an evaluation according to consolidated criteria for reporting qualitative research (COREQ). Results: By synthesizing the findings of the selected seven papers, a synthesized theme was emerged as "experiencing external and internal distances, which mandates authentic and consistent supports." The four sub-themes included 'experiencing some distance from the surrounded world,' 'experiencing self-made distance between the disease and oneself,' 'the disease experience causes social isolation and loneliness,' and 'there is lack of supportive care for myself.' Conclusion: Health care providers should be more attentive to supporting lung cancer patients by providing more effective advocacy programs that improve patients' quality of life.

  • Purpose: The purpose of the study was to understand and describe health-related experience of women with physical disabilities, using feminist qualitative approach. Methods: Eight women with physical disabilities participated to the study. Their mean age was 43, ranging from 39 to 67 years old. The data were collected by individual in-depth interviews and all interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed using traditional qualitative content analysis from a feminist perspective. Results: Six major categories emerged from the data. Category 1: "Isolation and alienation from the world.", Category 2: "A distorted self-image of physically disabled body.", Category 3: "Difficulties due to a fixed gender role.", Category 4: "Constant suffering from chronic pain.", Category 5: "Health problems that they have to endure by themselves.", Category 6: "Sublimation through self-reliance." The results of the study show how Korean women with physical disabilities suffer from social stigma, indifferences, and discriminations and struggle to survive in these unfriendly surroundings. Conclusion: The results of the study would help health professionals in designing effective intervention to improve health and to empower women with physical disabilities by providing deep understanding and critical insights of those women.

  • Purpose: The present study was done to discover the structure of universal actual experiences 'Considering tomorrow' of health and quality of life among North Korean refugees in terms of the socio-cultural context of South Korea. Method: The research question was 'what is the structure of the actual experience of 'Considering tomorrow?', which was examined based on the Parse's human becoming research method. Five North Korean adult refugees were recruited from a National Reconciliation Committee in Seoul/Incheon. The data was gathered from dialogues and collected from February, 2006 to November, 2006. Results: The structures found in this study were: 'hope for future life by taking responsibility and having harmony with South Koreans, by forming an integrated identification; having a chance for positive engagement, by attaining human freedom and hope; feeling respected, by assimilating self to the new world; getting freedom back, by facing a new challenge and preparing self for a new social role; overcoming cultural differences with fortified hardiness for survival, by making a decision for a life course with individual growth. In addition, conceptual integration was that 'Considering tomorrow is transforming the enabling-limiting values'. Conclusion: Health professionals need to know North Korean refugees' psychological difficulties, expectations of treatment, help seeking behavior, and expectations from mainstream culture. Additionally, understanding North Korean refugees' needs for reality, health education and a multi-disciplinary team approach are necessary to improve their health.
