Tunnelling is getting more important solutions for problems induced by the growth population in urban areas. Many studies on tunnelling below existing structure are carried out by many researchers. In general, however, ground water condition is ignored for most of researches using laboratory model test, so far. In case of ground behavior, error can occur if the result of effective stress related to hydraulic condition can't be taken into considerations. In this study, therefore, laboratory model test and the close range photogrammetry were conducted to investigate behaviour of ground and shallow foundation using newly device drainage system which is available to express the ground water condition. Also, numerical analysis was carried out to compare to results from the laboratory model test, and was performed with two methods, one is plastic and the other one is fully coupled analysis. Results from those two methods were compared to that of the laboratory model test.

Purpose: This study was designed to fine out the relationships among body image, self-esteem and health promotion behavior in mastectomy patients. Method: Data were obtained by self -reported questionnaires from 218 patients undergone mastectomy from September 1 to October 15, 2005. And data were analyzed using SPSS/PC WIN 12.0 program. For the statistical analysis of the date, frequency and percentage, mean and standard deviation, t-test, ANOVA and Scheffe test and Pearson's correlation coefficients were used. Result: The mean scores of the body image, self-esteem, and health promotion of the subjects were $41{\pm}7.40$ (range of scale : 17 to 68), $22.22{\pm}4.95$ range of scale : 10 to 40), and $130.45{\pm}23.99$ range of scale : 50 to 200), respectively. There were significant differences with the score of body image by the work type (F=4.018, p= .008), a number of child (F=3.069, p= .029), and participation with self help group program (t=68.177, p= .001). There were significant differences with the score of self-esteem by the type of religion (F=4.546, p= .002), work type (F=4.488, p= .004), post operation period (F=2.814, p= .026), and participation with self help group program (t=12.901, p= .001). There were significant differences with the score of the health promotion behavior by the type of religion (F=3.066, p= .018), economic state (F=11.765, p= .001), level of education (F=6.285, p= .001), operation site (F=.368, p=.027), family history (t=6.557, p= .011), and hope of breast reconstruction (t=7.025, p=.009). Relationship between body image and self-esteem showed moderate positive correlation (r=0.631, p= .001). The relationship between body image and health promotion behavior showed slightly positive correlation (r=0.257, p= .001). The relationship between self-esteem and health promotion behavior showed moderate positive correlation (r=0.431, p=.001). Conclusion: For the increasement of the health promotion behavior, it is needed to improve body image and self-esteem in mastectomy patients.

Lovastatin, one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid, lovastatin acid (LVA). Bioequivalence study of two lovastatin preparations, the test drug ($Mevacor^{\circledR}$: Chungwae Pharmaceutical Co., Ltd.) and the reference drug ($Lovaload^{\circledR}$: Chong Kun Dang Pharmaceutical Co., Ltd.), was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). Fourteen healthy male volunteers, $23.9{\pm}3.9$ years old and $67.6{\pm}8.0$ kg of body weight in average, were divided randomly into two groups and administered the drug orally at the dose of 160 mg as lovastatin in a $2{\times}2$ crossover study. Plasma concentrations of lovastatin acid were analysed by HPLC method for 12 hr after administration. The extent of bioavailability was obtained from the plasma concentration-time profiles of total lovastatin acid after alkaline hydrolysis of the plasma samples. By alkaline hydrolysis, trace amounts of unmetabolized lovastatin were converted to lovastatin acid. The $AUC_{0-12hr}$ was calculated by the linear trapezoidal rule method. The $C_{max}$ and $T_{max}$ were compiled directly from the plasma drug concentration-time data. Student's t-test indicated no significant differences between the formulations in these parameters. Analysis of variance (ANOVA) revealed that there were no differences in AUC, $C_{max}$, and $T_{max}$ between the formulations. The apparent differences between the formulations were far less than 20% (e.g., 7.07, 5.77 and 1.18% for AUC, $C_{max}$, and $T_{max}$, respectively). Minimum detectable differences(%) between the formulations at ${\alpha}=0.05$ and $1-{\beta}=0.8$ were less than 20% (e.g., 17.2, 15.1, and 15.9% for AUC, Cmax, and Tmax, respectively). The 90% confidence intervals for these parameters were also within ${\pm}20%$ (e.g.. $-5.20{\sim}19.3$, $-5.00{\sim}16.5$, and $-10.2{\sim}12.5%$ for AUC, $C_{max}$, and $T_{max}$, respectively). These results satisfied the bioequivalence criteria of KFDA guidelines, indicating that the two formulations of lovastatin were bioequivalent.

Objectives: The purpose of the study is to investigate the relationship between bone mineral density and remaining teeth in Korean adults. Methods: Using National Health and Nutrition Examination Survey(KNHANES) 5th Year 1(2010), 1,985 adults over 50 years old having bone mineral density test were selected. Male adults were 883, and female adults were 1,102. The raw data consisted of general characteristics of the subjects, bone density data, and oral examination data. The questionnaire consisted of general health survey, laboratory examination study, and nutrition study. Data were analyzed using SPSS 18.0 program for multiple regression analysis, ANOVA, t-test. The variables included general characteristics of the subjects, health behavior, diet habit, and oral health behavior. General characteristics consisted of gender, age, residence area, education level, marital status, monthly income, and vocation. Health behavior consisted of smoking, alcohol drinking, body mass index(BMI), physical activity, and mental health. Diet habit consisted of frequency of meal, milk, coffee, and calcium ingestion. Oral health behavior consisted of frequency of tooth brushing, use of oral health care devices, and oral examination. Systemic diseases were measured by the questionnaire for hypertension, diabetes mellitus, and hyperlipidemia. Bone density was measured in T-score of femoral bone, neck of femur, and lumbar vertebrae. Bone density was classified into normal($T-score{\geq}-1.0$), osteopenia(-2.5 < T-score < -1.0), and osteoporosis ($T-score{\leq}-2.5$). The remaining teeth were measured by the differences between normal teeth and missing teeth. Results: Smoking and age are the most influencing factors on the number of remaining teeth and bone density(p<0.01)(p<0.05). Those who had higher bone density, younger age, and nonsmoker significantly had more remaining teeth. Those who were men, diabetic, lowly educated women, and low birth weighted persons tended to have less number of teeth(p<0.01). Conclusions: The study suggested that there were significant differences between men and women according to the oral health management behavior and systemic disease control. Proper management of the oral health and good quality of bone mineral density can reserve the remaining teeth through the whole life.

Objectives: The purpose of this study was to determine whether the sacrooccipital category II blocking technique may improve abdominal muscle endurance and alleviate shoulder pain caused by pelvic tilting. Methods: A total of 50 subjects diagnosed with category II sacroiliac joint instability and lower back pain were randomly assigned to the control or treatment group. The sacrooccipital technique category II blocking procedure (2-min duration) was performed 3 times a week until the category II indicator of joint instability had subsided. The control subjects were subjected to a sham procedure of equal duration and frequency. We assessed abdominal muscle endurance using the partial curl-up test and shoulder pain using a visual analogue scale, before and immediately after the intervention and 2 weeks after the intervention. Results: On two-way analysis of variance with repeated measures on time factor, significant treatment and interaction effects on muscle endurance were found. A significant interaction effect, but not treatment effect, was found for shoulder pain. Post hoc test showed that the shoulder pain was reduced immediately after intervention (treated group) and 2weeks (control and treated group) after the intervention as compared to before the intervention. Conclusions: This study suggests that sacrooccipital category II blocking can be used to alleviate shoulder pain caused by pelvic instability. The mechanisms behind the long-term benefits may include an increase in abdominal muscle endurance.

The purposes of this study were to find out the effects of hospice care for the quality of life of the terminally - ill patients and to analyze the relationship between the effect of hospice care and the general characteristics of subjects. The subjects of the study were 32 terminally - ill patients hospitalized in the two general hospitals in Seoul, which have the hospice care unit. The data were collected using the questionnaire with interviews. They were done from Sept.28, 1989 to March 20, 1991. The tools used for the research were 17-item questionnaire regarding general characteristics, 42-item questionnaire about the quality of life (11- item for physical, 16 for psychosocial, and 15 for spiritual). The questionnaires were to measure the duality of life by means of the measure instruments of Betty R. Farewell(1989), Stein Kaasa(1988), Palm Pamela(1987), and Hwa-sook Choi(1987). 42 items were used after pre-test. In accordance with each purpose in this study, frequency and percentage were used on the general characteristics of subjects. ANOVA, t-test, and Pearson correlation were employed to evaluate the general characteristics of subjects and different level of quality of life before-and-after hospice care. The results of the study may be summarized as follws : 1. The effects of hospice care. Main Hypothesis : “The quality of life of the terminally - ill patients will be different from before-and-after hospice care” was supported(t＝6.82, df＝31, p＝ .000). Sub Hypothesis 1 : “The quality of life of the terminally - ill patients in the physical aspects will be different from before - and -after hospice care” was not supported(t＝0.07, df＝31, p＝ .946). Sub Hypothesis 2 : “The quality of life of the terminally - ill patients in the psychosocial aspects will be different from before-and-after hospice care” was supported (t＝4.69, df＝31, p＝ .000). Sub Hypothesis 3 : “The quality of life of the terminally - ill patients in the spiritual aspects will be different from before-and-after hospice care” was supported(t＝6.64, df＝31, p＝ .000). 2. Relationship between the general characteristics of subjects and the effects of hospice care. (1) The more the number of family, the higher the quality of life in the psychosocial aspects. (2) The higher the age of the patient, the lower the quality of life in the psychosocial aspects. (3) The high educational level of patients enjoy the high quality of life in general. (4) The high religious level of petients enjoy the higy Quality of life in the spiritual aspects. As a results of analysis above : 1. The most effective aspects of the hospice care to the terminally- ill patients was spiritual aspects. The next effective aspects was psychosocial area. 2. The least effective aspcets of the hospice care to the terminally- ill patients was physical aspects. Further study is needed to improve the quality of life in the physical aspects.

The purpose of this study was to identify factors influencing the transfer of learning for nursing students in clinical practice. This study is a descriptive survey research conducted with 113 nursing students. Self-directed learning, motivation to transfer, and transfer of learning were measured. Data were analyzed by descriptive analysis, independent t-test, and ANOVA. The transfer of learning were significantly different according to the interpersonal relationship (t=10.43, p=.002), the satisfaction of nursing major (t=3.81, p=.006), satisfaction of nursing skills laboratory (t=4.61, p=.004). Transfer of learning had a correlation with self-directed learning, motivation (r=.46, p=<.001), and motivation to transfer (r=.60, p=<.001). In addition, motivation to transfer, the satisfaction of nursing skills laboratory, and learning evaluation were significant predictors of transfer of learning. Finally, in order to increase the transfer of learning for nursing students, nursing instructors need to encourage motivation to transfer, and to apply educational strategies that increase self-directed learning, as well as the satisfaction of the nursing skills laboratory.

The slope collapse can be classified into internal and external factors. Internal factors are engineering factors inherent in the formation of slopes such as soil depth, slope angle, shear strength of soil, and external factors are external loading such as earthquakes. The external factor for earthquake can be expressed by various values such as peak ground acceleration (PGA), peak ground velocity (PGV), Arias coefficient (I), natural period (T_p), and spectral acceleration (S_aT=1.0). Specially, PGA is the most typical value that defines the magnitude of the ground motion of an earthquake. However, it is not enough to consider the displacement in the slope which depends on the duration of the earthquake even if the vibration has the same peak ground acceleration. In this study, numerical analysis of two-dimensional plane strain conditions was performed on engineered block, and slope responses due to seismic motion of scaling PGA to 0.2 g various event scenarios was analyzed. As a result, the response of slope is different depending on the presence or absence of sliding block; it is shown that slope response depend on the seismic wave triggering sliding block than the input motion factors.
