This study was conducted using the phenomenological research method to collect and analyze high school students' opinions about fusing "science" textbook that reflect the 2009 Revised Curriculum. Ninety six students were chosen to be participants from 32 high schools that selected by city and province. The data collection was carried by individual interviews and group discussions. The results are as follow; students' opinions were summarized to 50 themes, and then classified to 9 theme clusters and 2 categories. Students' opinions were divided into a positive position - "it is good because interesting material associated with life", "the structure of textbook is good", "teachers' efforts make class interesting", and "it will help in career choices"- and negative position - "the content is difficult to understand", "the configuration is complex", "I have less interest about it because it doesn't related College Scholastic Ability Test", "teacher's explanation is insufficient", and "it is not associated with career choice"-. The living-related material and story-telling configuration received good reviews from students. On the other hand, the configuration of topics makes many concepts to use, so students have difficulty understanding the content and pointed out the lack of teachers' explanations about unfamiliar areas. In order to solve the difficulties, variety teaching material for fusing "science" will be developed.

Purpose : The purpose of this study is to understand the experiences of nursing students in clinical practice at a public health center through their self- reflections. Subjects : The 110 students in the 3rd year, practice at two public health centers in city P and city K. From the110, 53 male and female university students who practice in city K were selected to participate : 11males (20.8 %) and 42 females (79.2 %). Methods : The data analyzed were the self-reflections regarding the clinical practice. Results : These data indicate that : most of the participants now believe that public health centers provide many more services to the community than they previously knew about. They rate the public health center's programs highly, and want to be community health nurses. For the first time, they realize that the work of public health nurses is very important. In particular they note that their emotions while at the public health center differ significantly from when they work at the other. The environment in the public health center makes them feel more comfortable and less stressed. Generally, they are satisfied with their practice at the public health center. Conclusion : On the basis of these findings, the following recommendations can be made. Experience at public health centers is an important part of nursing students' education. I suggest that research on nursing students' experiences while practicing at the public health center should expand to include research methods other than the analysis of their reflection journals, In addition a follow-up study of experiences while practicing at the public health center should be attempted of self-reflections.

Purpose: To develop the dose volume histogram (DVH) management software which guides the evaluation of radiotherapy (RT) plan of a new case according to the biological consequences of the DVHs from the previously treated patients. Materials and Methods: We determined the radiation pneumonitis (RP) as an biological response parameter in order to develop DVH management software. We retrospectively reviewed the medical records of lung cancer patients treated with curative 3-dimensional conformal radiation therapy (3D-CRT). The biological event was defined as RP of the Radiation Therapy Oncology Group (RTOG) grade III or more. Results: The DVH management software consisted of three parts (pre-existing DVH database, graphical tool, and $Pinnacle^3$ script). The pre-existing DVH data were retrieved from 128 patients. RP events were tagged to the specific DVH data through retrospective review of patients' medical records. The graphical tool was developed to present the complication histogram derived from the preexisting database (DVH and RP) and was implemented into the radiation treatment planning (RTP) system, $Pinnacle^3$ v8.0 (Phillips Healthcare). The software was designed for the pre-existing database to be updated easily by tagging the specific DVH data with the new incidence of RP events at the time of patients' follow-up. Conclusion: We developed the DVH management software as an effective tool to incorporate the phenomenological consequences derived from the pre-existing database in the evaluation of a new RT plan. It can be used not only for lung cancer patients but also for the other disease site with different toxicity parameters.

Objectives: The purpose of this study is to understand the cognition of the initiation of diseases of North Korean refugees in South Korea. Methods: 9 North Korean refugees hospitalized in Oriental Neuropsychiatry of National Medical Center participated in the interview. The statements were analyzed by using the phenomenological research methodology and Giorgi's analytical method, in particular, was applied. Results: A total of 4 categories and 15 sub categories were derived from the participants' descriptions. North Korean refugees who thought their diseases have begun while living in North Korea coming to South Korea, have fire disease because of the strict social system, limitations imposed on their actions, and the violence of their husbands. And who thought during escaping from North Korea, have anxiety about being killed, found and transferred to North Korea. They also suffered from a sense of guilt towards their family who were left behind as well as from depression. Consequently, they thought their skeletal diseases have begun during this period. Who thought during their period in Korea, their diseases like fire disease and depression have been worsen because of unfamiliar circumstances and doctors who said their problems had been caused by psychiatric disorder. Nevertheless, they did their jobs, felt happy and had a will to be cured thingking possibilities of overcoming diseases. Conclusions: These results suggest that various factors during different periods in the life of North Korean refugees could have an effect on their present diseases.

Objectives: This study aims to investigate the married female immigrants' experience on Korean dietary life adaptation, especially identifying the symbolic meaning and nature of experiences. Methods: This study was conducted with six married female immigrants through an analysis of the qualitative materials which consisted of in-depth interviews, field notes and materials. Data was analyzed using Giorgi's phenomenological research methods. Results: The results were deduced as 116 significant statements, 17 formulated meanings (sub-theme), and 6 theme clusters. Six theme clusters comprised of lack of preliminary knowledge and information, conflict and support in relationships, Korean food culture which is different from homeland, adaptation attitudes of Korean food culture according to situation, sharing of homeland food culture, and practical difficulty and expectative service. The participants started Korean life in the dark about Korea and Korean food culture, so they were subjected to trial and error. The conflict between Korean mother-in-law and foreign daughter-in-law came from lack of consideration of daughter-in-law's cultural background. Some participants were hurt because of misunderstanding and nitpicking. They were learning about cooking method, ingredient, seasoning, table setting and manner. Some participants integrated Korean food culture and their homeland food culture. Some of them assimilated with Korean food culture. One of them maintained homeland food culture. The participants who adapted Korean food culture well could share homeland food amicably. They sometimes didn't apply the services which were offered by the government, because the services did not fit their needs. Some of them didn't know the usage route of the services or information. They had resistance about home teaching and it showed that outreach service was not always effective. Conclusions: This study suggested that it is necessary to develop a practical support plan which covers married female immigrants' real needs and system improvement measures.

The groutability depends on the properties of the grout, its injection processes, and on the mechanical properties of the soil formation. During the process of pouring cement-based grouting into a porous medium, a variation with time occurs in the viscosity of grout suspension. In addition the particle filtration phenomenon will limit the expansion of the grouted zone because cement particles are progressively stagnant within the soil matrix. In this paper, a closed-form solution was derived by implementing the mass balance equations and the generalized phenomenological filtration law, which can be used to evaluate the deposition of cement-based grout in the soil matrix. The closed-form solution relevant to a particular spherical flow was modified by a step-wise numerical calculation, considering the variable viscosity caused by a chemical reaction, and the decrease in porosity resulting from grout particle deposition in the soil pores. A series of pilot-scale chamber injection tests was performed to verify that the developed step-wise numerical calculation is able to evaluate the injectable volume of grout and the deposition of grout particles. The results of the chamber injection tests concurred well with that of the step-wise numerical calculation. Based on the filtration phenomenon, a new groutability criterion of cement-based grout in a porous medium was proposed, which might facilitate a new insight in the design of the grouting process.
