After kidney transplantation, immunosuppressive medication is essential to enhance the quality of life and survival of the transplanted patient. To promote the medication adherence, subjects are required to have converged attitude with open mind. Medication adherence will depend on the attitude of the psychosocial characteristics and treatment guidelines. The purpose of this study was to identify the specific types and characteristics of medication adherence in the view of kidney transplanted patients. Q-methodology, a technique for extracting subjective opinions, was used. Forty participants completed the Q-sort activity, rating each statement relative to the others. The collected data were analyzed by QUANL PC program. Four types of medication adherence of kidney transplanted patients were identified: 'positive lifestyle management type', 'vigilant appearance management type', 'somber oblivion type', 'vigilant family support type'. Through the identification of attitudes to medication adherence, repeated and individualized medication adherence program will help to prevent graft rejection.

Purpose : The purpose of this study is to investigate the effect of squat exercise using a ball on the gap between knees and Q angle of a subject with a genu-varum, and to prove the effect, to provide a clinical basis for developing into a knee correction exercise program. Methods : As a result of posture measurement through GPS, 26 female with genu-varum with a knee length of 5 cm or more were studied. The group was randomly assigned to 13 squat exercise group using ball (experimental group) and 13 general squat exercise groups (control group). The experimental group placed the ball between both knees in a position where the distance between both feet was slightly wider than the shoulder width on a flat support surface, and fixed the ball, and then squat with the start signal. The control group squats without a ball. Each group performed three sets of exercise three times a week for six weeks. Before their exercise, after three and six weeks, EMG, GPS, digital goniometer measurement, the vastus medialis (VM), the vastus lateralis (VL), and the Q-angle were measured in the squat exercise posture. EMG was measured in squat exercise posture. Results : The distance between the knees was reduced. EMG is activated in group A, the group B experimental results showed the high activity of the VL. Q-angle had increased. But the experimental group increased more than the control group. Conclusion : We have confirmed through our experiments that the distance interval between the knees during squat exercises using a ball can be reduced. Furthermore, it would also be helpful to ensure the treatment of genu-varum.

Purpose: Although the price reduction policy is established for military supplies, it is more focused on general military items. Therefore, it is hard to apply the current price reduction policy directly to the major weapon system. The purpose of this study is to develop an evaluation model which generates appropriate outputs for price reduction of military supplies. Methods: To improve the current policy, we first analyze the relevant policies of price reduction of similar organizations. We gather the opinions of related organization through survey including DAPA, Logistics Command, DTaQ and Defense industry companies. Then, we develop a price reduction model based on the analytic hierarchical process(AHP) method to find out important factors for price reduction. Results: The results of AHP analysis show that the important factors when applying price reduction of military supplies. From the analysis, the proposed method effectively generates the amounts of price reduction for the nonconformance items. Conclusion: The results of this research will be used as guidelines to improve military supplies policy of price reduction.

In construction of a structure in underground space, in-situ stress in rock mass has great effect on the stability of the structure. Especially, the direction and magnitude of rock stress have influence on the excavation method, the choice of support and reinforcement method for establishing the stability of tunnel. Therefore, it is very important to consider the characteristics of in-situ stress in rock mass for tunnel stability analysis. In this study, a reasonable design method for underground structure was reviewed through the case study for tunnel design considering in-situ rock stress. For this purpose, the estimation for SRF (Stress Reduction Factor) as input parameter in rock classification using Q-System and the assesment for tunnel support were studied. Also, considering the characteristics of in-situ rock stress such as the magnitude of K and the direction of principal stress, the parameter studies for tunnel stability analysis were carried out. An improved method was proposed for obtaining the better results in the tunnel stability analysis.

Purpose: This study was conducted to identify subjective attitudes towards terminal patients in nursing students who had clinical practice. The types of subjective attitude were classified by applying Q methodology. According to those types, basic reference data for the development of educational programs were provided. Methods: Thirty-four final Q samples were selected, and Q classification with a nine-point scale was performed with P samples of 43 nursing students. A key factor analysis was conducted with the collected data using the PC QUANAL program. Results: Nursing students' attitudes towards terminal patients were grouped into three types. The total variable was 49.96%. Students with Type 1 ("wish for life-sustaining medical treatment") thought that terminal patients accurately understood their medical condition and wanted to prolong their lives. Others with Type 2 ("need for service and support") believed that a multidisciplinary nursing system needs to be established to help terminal patients prepare for death. Students with Type 3 ("awareness and acceptance of death") thought that terminal patients wanted to die with dignity at a hospice unit. Conclusion: This study analyzed various types of attitude towards terminal patients, as perceived by nursing students with clinical training experience. Development of educational programs for each attitude type analyzed in this study could contribute to systematic training programs for nursing students caring for terminal patients.

An alternative molecular porphyrin-phthalocyanine aggregate was prepared and characterized with UV-visible and X-ray absorption spectroscopies. UV-visible experiments evidence 1-dimensional porphyrin-phthalo-cyanine array formed by mixing $SnTPPCl_2 ({\lambda}_{max}=429,\;{\varepsilon}=2.4{\times10^ 5 /M{\cdot}cm)\;and\;NiPc(OBu)_8({\lambda}_{max}=744 nm,\;{\varepsilon}= 2.0{\times}10^ 5 /M{\cdot}cm)$ in solution. In the UV-visible spectrum of the porphyrin-phthalocyanine array, $(SnPNiPc)_n$, a new Q-band appeared at 844 nm with decrease of the Q-band peak of $NiPc(OBu)_8$ at 744 nm. The red-shift of Q-band evidences an alternative porphyrin-phthalocyanine array formed in solution through metal-halide interaction rather than ${\pi}-{\pi}$ facial interaction, in which nickel of $NiPc(OBu)_8$ coordinates with chloride of $SnTPPCl_2$ through self assembly. Ni K-edge XANES (X-ray absorption near edge structure) spectra also support the axial ligation of nickel to chloride. The square planar structure of $NiPc(OBu)_8$ turns to an octahedral structure in (SnPNiPcSnP) by axial ligation. A higher energy-shift (0.2 eV) of the preedge peak of (SnPNiPcSnP) indicaties partial oxidation of nickel by charge transfer from NiPc$(OBu)_8$ to SnTPPCl$_2$.

Electrical resistivity is one of physical property of the earth and measured by electrical resistivity survey, electrical resistivity logging and laboratory test. Recently, electrical resistivity is widely used in determination of rock quality in road and railway tunnel design. To get more reliable rock quality data from electrical resistivity, it needs a lot of test and study on correlation of resistivity and rock quality. Firstly, we did rock property test in laboratory, such as uniaxial compressive strength(UCS), p wave velocity, Young's modulus and electrical resistivity. We correlate each test results and we found out that electrical resistivity has exponentially related to UCS and P wave velocity and linearly related to Young's modulus. And we accomplished electrical resistivity survey in field site and carried out electrical resistivity logging at in-situ area. Also we peformed rock classification, such as RQD, RMR and Q-system and we correlate electrical resistivity to rock classification results. We found out that electrical resistivity logging data are highly correlate to RQD, Q and RMR. Also we found out that electrical resistivity survey data are lower than electrical resistivity logging data when there are faults or fractures. And it cause electrical resistivity survey data to lowly correlate to RQD, Q and RMR.

Purpose: The purpose of this study was to identify and understand the self-directed learning patterns of nurses. Q methodology was used to collect the data. Method: For the research method, 43 Q-statements were collected through individual interviews and a review of related literature. The 43 Q-statements were classified by the 34 participants in the study and the data was analyzed by the PC-QUANL program with principal component analysis. Result: There were 4 different patterns of self-directed learning classified as follows : Nurses in Type I the Future Provision Type, studied to promote their own professional development and leadership qualities for the future. Nurses in Type II, the Learning Passion Type, enjoyed learning something new and had a strong learning desire. Nurses in Type III, the Self-reflective Type, continuously evaluated self and their own practice by introspection. Nurses in Type IV, the Accompanying Companion Type, studies with companion support and maintained a collaborative relationship rather than competing with each other. Conclusion: This study explains and allows us to understand self-directed learning in nurses. Thus this study will contribute to building a theoretical base for the development of a self-directed learning model in nursing practice.
