Purpose: This study examined the effects of spirituality promoting intervention for the stomach and colon cancer patients. Method: A quasi- experimental design was used. Data collection was carried out from April 2004 to June, 2004 at a cancer center in Korea. The intervention included pray, meditation, group education and discussion for coping with cancer. The experimental group were received a 1-hour intervention per week for 6 weeks, while the control group received usual care. Data collection was done at pre and post intervention. The degree of spirituality was measured by the Korean version of WHOQOL-SRPB pilot test(WHO Quality of Life-Spirituality, Religiousness and Personal Beliefs pilot test) Module, and social support was measured using scores on a PRQ 85(Personal Resources Questionnaire). Fighting spirit was measured by the scores of MAC(Mental Adjustment to Cancer) scale. Results: The experimental group showed significant increase in the scores of social support and fighting spirit compared to those in the control group after the intervention. There were no significant changes in terms of the spirituality score compared to the baseline score in the experimental group and the control group. Conclusion: This intervention appeared to be effective in increasing social support and fighting spirit, which considered to be very helpful in cancer adjustment.

Purpose: This study was to identify the effects of self-foot reflexology on urinary incontinence symptoms, vaginal contraction and daily life discomfort of middle-aged women. Method: A quasi-experimental design was used. The subject were 39 middle-aged women with urinary incontinence, who were composed of 18 women in the experimental group, while 21 were in the control group. In the experimental group, self-foot reflexology was applied for 30 minutes, three times a week for 4 weeks. The obtained data were analyzed by using the Mann-Whitney U test of SPSS. Result: 1. Frequency(U=78.00, P=.001), amount(U=65.00, p=.001) and the situation score(U=81.00, P=.002)of urinary incontinence were reduced significantly in the experimental group as compared to the control group. 2. Maximum pressure(U=33.50, p=.000), mean pressure(U=38.00 p=.000) of vaginal contraction were improved significantly in the experimental group as compared to the control group. 3. Daily life discomfort in the experimental group was reduced whereas that of the control group was increased(U=63.00, p=.000) significantly. Conclusion: These findings indicate that self-foot reflexology is an effective method for reducing urinary incontinence symptoms and daily life discomfort and for increasing pressure of vaginal contraction of middle-aged women. Therefore self-foot reflexology can be considered as a independent nursing intervention for urinary incontinence.

The purpose of this study was to determine an effect of the health camp program on self-efficacy, sick-role behavioral compliance and glucose metabolism in juvenile diabetes mellitus patients. The quasi -experimental study was designed using a nonequivalent control group pre-posttest design with the framework of Bandura's self-efficacy theory. Forty-two juvenile diabetes mellitus patients participating in this study were selected from outpatients. Of these, twenty-one were assigned to the experimental group and twenty-one to the control group. The period of data collection was from August 8 to December 9 in 1994. The health camp program for the experimental group was carried out over 6 days and the control group did not participate in the program. Collection data was analyzed by means of chi - square test, t - test, ANCOVA, Pearson correlation with SPSS /PC+. The result were summarized as follows: 1. The health camp program was effective in in-creasing the scores of self-efficacy for juven-ile diabetes mellitus patients. 2. The health camp program was effective in increasing the scores of sick - role behavioral compliance for juvenile diabetes mellitus patients. 3. The health camp program was not effective in decreasing the levels of glucose metabolism. 4. The more self-efficacy increased, the more sick - role behavioral compliance increased. 5. Boys showed the higher self-efficacy than girls and the group with diabetes patients whose family members are also patients, showed the higher self-efficacy and sick-role behavioral compliance than the group without diabetic patient among the family members. Thus, it can be concluded that the health camp program was a useful health intervention for juvenile diabetes mellitus patients.

Signal transmission and crosstalk of coupled bondwires buried in plastic packages are analyzed using the Method of Moments and the Fourier Transform algorithm. It is also shown that the quasi-static crosstalk model of SPICE is inappropriate for designing the high-speed plastic packages. Plastic packaging material, increasing the self and mutual capacitances, is found to be helpful for the signal transmission integrity due to the dielectric compensation effect. However, it is also observed that the plastic material increases the crosstalk due to the radiation-enhanced mutual coupling effect. By investigating the geometrical and material dependence of the pulse transmission and crosstalk, it is found that the radiation-enhanced coupling effect is significant for most of typical bondwire geometries and plastic package materials. These calculation results can be effectively used for designing plastic packages of high-speed digital IC's and monolithic RFIC's.

Purpose: This study was undertaken to test effects of action oriented BSE education on knowledge, selfefficacy, and performance competence in nursing students. Methods: A non-equivalent pre-posttest of time serial quasi-experimental design was used to prevent diffusion of the experiment. Out of 53 nursing students selected by convenient sampling in the third grade at a nursing college, 27 students were randomly assigned to the control group and were first given a traditional lecture on BSE. For the experimental group of 26 students action oriented BSE education consisted of lectures, demonstrations with breast models, and BSE skill practice by micro teaching. Results: There was no significant difference in general and BSE-related characteristics between the two groups. Scores of the experimental group in knowledge, self-efficacy, and performance after the intervention were significantly higher than those of the control group. Conclusions: Results showed that action- oriented BSE education was effective in increasing knowledge, self-efficacy and performance competence in nursing students. Education for students should incorporate strategies reinforcing confidence by practicing actual BSE skills as well as acquiring knowledge of BSE, so that students can become competent and practical cancer prevention educators.

Background: The current study investigated the effects of Piper longumine on radio-sensitization of human breast cancer MDA-MB-231 cells and underlying mechanisms. Materials and Methods: Human breast cancer MDA-MB-231 cells were cultured in vitro and those in logarithmic growth phase were selected for experiments divided into four groups: control, X-ray exposed, Piper longumine, and Piper longumine combined with X-rays. Conogenic assays were performed to determine the radio-sensitizing effects. Cell survival curves were fitted by single-hit multi-target model and then the survival fraction (SF), average lethal dose ($D_0$), quasi-threshold dose ($D_q$) and sensitive enhancement ratio (SER) were calculated. Cell apoptosis was analyzed by flow cytometry (FCM). Western blot assays were employed for expression of apoptosis-related proteins (Bc1-2 and Bax) after treatment with Piper longumine and/or X-ray radiation. The intracellular reactive oxygen species (ROS) level was detected by FCM with a DCFH-DA probe. Results: The cloning formation capacity was decreased in the group of piperlongumine plus radiation, which displayed the values of SF2, D0, Dq significantly lower than those of radiation alone group and the sensitive enhancement ratio (SER) of D0 was1.22 and 1.29, respectively. The cell apoptosis rate was increased by the combination treatment of Piper longumine and radiation. Piper longumine increased the radiation-induced intracellular levels of ROS. Compared with the control group and individual group, the combination group demonstrated significantly decreased expression of Bcl-2 with increased Bax. Conclusions: Piper longumine at a non-cytotoxic concentration can enhance the radio-sensitivity of MDA-MB-231cells, which may be related to its regulation of apoptosis-related protein expression and the increase of intracellular ROS level, thus increasing radiation-induced apoptosis.

A series of Quasi-Elastic Neutron Scattering (QENS) experiments helps us to understand the single-particle (hydrogen atom) dynamics of a globular protein and its hydration water and strong coupling between them. We also performed Molecular Dynamics (MD) simulations on a realistic model of the hydrated hen-egg Lysozyme powder having two proteins in the periodic box. We found the existence of a Fragile-to-Strong dynamic Crossover (FSC) phenomenon in hydration water around a protein occurring at TL=$225{\pm}5K$ by analyzing Intermediate Scattering Function (ISF). On lowering of the temperature toward FSC, the structure of hydration water makes a transition from predominantly the High Density Liquid (HDL) form, a more fluid state, to predominantly the Low Density Liquid (LDL) form, a less fluid state, derived from the existence of a liquid?liquid critical point at an elevated pressure. We showed experimentally and confirmed theoretically that this sudden switch in the mobility of the hydration water around a protein triggers the dynamic transition (so-called glass transition) of the protein, at a temperature TD=220 K. Mean Square Displacement (MSD) is the important factor to show that the FSC is the key to the strong coupling between a protein and its hydration water by suggesting TL${\fallingdotseq}$TD. MD simulations with TIP4P force field for water were performed to understand hydration level dependency of the FSC temperature. We added water molecules to increase hydration level of the protein hydration water, from 0.30, 0.45, 0.60 and 1.00 (1.00 is the bulk water). These confirm the existence of the FSC and the hydration level dependence of the FSC temperature: FSC temperature is decreased upon increasing hydration level. We compared the hydration water around Lysozyme, B-DNA and RNA. Similarity among those suggests that the FSC and this coupling be universal for globular proteins, biopolymers.

Medical clinics are core institutes that cover the primary medical care in Korea. Financial viability of the clinics is essential for them to conduct their roles and functions, and can be improved by increasing their operating profitability. On this ground, this study aimed at finding important factors that affect the operating profitability, and thereby at suggesting strategic alternatives that can contribute to the improvement of the profitability. Operating margin was set as a dependent variable, and such factors as general management conditions, number of visits, medical revenue, marketing activities, input resources, medical cost as independent variables. Nineteen hypotheses related to the variables were established and tested using data collected from 138 sample clinics for the year 2003. The results of the study are as follows : Firstly, such variables as percent ratio of the depreciation plus rent costs to total administration costs, type of clinical department manifested whether medical, surgical, or quasi-surgical, percent ratio of the interior facility investment to total fixed assets, and total number of outpatient visit are important factors that affect, positively or negatively, the medical profitability of the clinics. Secondly, following measures are needed to be established and implemented to improve the medical profitability. (1) Administration costs share 53.2% of the total medical costs, and depreciation plus rent costs 16.3% of the total administration costs. This implies that such measures as reinforcement of marketing activities, establishment of the cooperative utilizing system of the facility and equipment, or group practice are needed to increase cost-effectiveness. (2) Occupancy rate of the clinics with inpatient bed is as low as 45.5%, causing high fixed costs and low medical profitability. For its improvement, the resource input structure should be reorganized. Thirdly, in the future, a study that can increase sample representativeness of the study and explanation power of the variables should be performed for each type of clinical department to find more specific determinant factors and to contribute to the improvement of the medical profitability of the clinics.

The incompetency and quasi-incompetency system regulated legal incompetence in the past is insufficient for protections of the adults with insufficient abilities of judgement, the criticism has been continued that the system is not efficiently respond to their rights and legal relationship formation. At last, the government introduces adult guardianship system through revising the civil law. At this point, just several months prior to the enforcement of adult guardianship system, we should be prepared to issues which may occur in the actual operation of the system. Japan has high similarities in social and culture matters with Korea and in the general operation of its adult guardianship system is similar to Korea's, Therefore, Korea should be prepared for the basis to implement the optimized system through in advance understanding the trend in Japan. The study reviews the trends of Japanese adult guardian's type, and draws suggestions for Korea by finding activity requirements and subjects focusing on the currently increasing corporation guardiancy.
