Purpose: This study examined the various patterns of standing to squatting activities, and reports the testing standard and phases for examining the standing to squatting position. Methods: One thousand, normal college students (500 males, 500 females) volunteered for this study. The patterns are performed by naked eye analysis with two video cameras. Results: The patterns from the standing to squatting position are as follows 1. parallel with the heel on the pattern: 2. parallel with the heel off the pattern: 3. closed with the heel on the pattern: 4. closed with the heel on the pattern: 5. open with the heel on the patternand 6. open with the heel on the pattern. Conclusion: The phases of the standing to squatting position are as follows: phase I from standing to the anterior parts of the knees reaching the anterior limit of the BOS, phase II from phase I until the height of the hip and knee joints are the same, phase III from phase II until there was no full squatting and the heels broke contact with the floor and phase IV from phase III full squatting on the heels in contact with the floor.

Cancer has been considered a life-threatening disease and coping patterns could have a strong impact the physical and psychological health of patients and their family. The purpose of this study was to identify the change of coping patterns according to the phases of illness in the patients with cancer and their family caregivers and to compare the coping patterns of patients with those of their caregivers. The phases of illness consisted of 1st(initial) stage, 2nd(metastatic or recurred) stage and 3rd (terminal) stage based on literature. The coping methods were measured using the modified Ways of Coping Questionnaire by Lazarus & Folkman(1984). Seventy-nine patients(35 in stage 1, 31 in stage 2, and 13 in stage 3) and ninety-two caregivers (38 in stage 1, 30 in stage 2 and 24) agreed to participate from two general hospitals in Seoul and Choongnam. No significant changes were found in the coping patterns according to the phases of illness in both groups. Patients in stage 2 and caregivers in stages 2 and 3 problem-focused coping methods were significantly used more than emotion-focused coping methods. Patients in stage 1 significantly used two coping strategies that were cognitive reconstruction and emotion expression more than caregivers. Patients in stage 2 significantly used emotion-focused coping methods including minimizing threat, blame, and emotion expression excepting wishful thinking more than caregivers. We need more research to identify the relationship between the coping methods and their efficiencies through longterm observation and attempt to develope the nursing interventions that could have an improvement on positive coping methods and provide guidance on the problems the patients experience.

Purpose: Effective communication is an essential aspect of nursing care. This qualitative study was performed to analyze nurse-patient conversations about medication. Method: The nurse-patient dialogue was collected by video tape recording during the nurse's duty time in an internal medicine ward. One hundred seventy-eight episodes were extracted from the conversation. Using conversational analysis, the functional phases and patterns of dialogue sequence pertaining to medication were analyzed. Results: Conversations about medication were very brief dialogues, so 68.8% of the dialogue had a duration of less than 20 seconds. However, it was a systematic and comprehensive dialogue which had structures and sequential dialogue patterns. Four functional phases were explored. greeting, identifying the patient, medicating, finishing. The medicating phase was essential, in which the nurse gave the drug to the patient and provided information initiated by the nurse simultaneously. The patterns of the dialogue sequence represented were the nurse provided information first, and then, patients responded to the nurse as accepting, rejecting, raising an objection, or asking again later. Conclusion: As the results of this study show, a nurse's role is important as an educator. For effective conversation about medication, the development of an educational program should be considered, which includes knowledge about medication and communication skills.

Purpose: The purpose of the study was to identify functional structure and patterns of dialogue sequence in conversations between elderly patients with dementia and nurses in a long-term care facility. Methods: Conversation analysis was used to analyze the data which were collected using video-camera to capture non-verbal as well as verbal behaviors. Data collection was done during February 2005. Results: Introduction, assessment, intervention, and closing phases were identified as functional structure. Essential parts of the conversation were the assessment and intervention phases. In the assessment phase three sequential patterns of nurse-initiated dialogue and four sequential patterns of patient-initiated dialogue were identified. Also four sequential patterns were identified in nurse-initiated and three in patient-initiated dialogues in the intervention phase. In general, "ask question", "advise", and "directive" were the most frequently used utterance by nurses in nurse-initiated dialogue, indicating nurses' domination of the conversation. At the same time, "ask back", "refute", "escape", or "false promise" were used often by nurses to discourage patients from talking when patients were raising questions or demanding. Conclusion: It is important for nurses to encourage patient-initiated dialogue to counterbalance nurse-dominated conversation which results from imbalance between nurses and patients in terms of knowledge and task in healthcare institutions for elders.

Mixed-conducting oxide powders, $BaCe_{0.9}Y_{0.1}O_{2.95}$ (BCY) and $SrCe_{0.9}Y_{0.1}O_{2.95}$ (SCY) powders have been prepared by a solid-state reaction method. Xray diffraction patterns of the prepared powders showed the sharp peaks of the $BaCe_{0.9}Y_{0.1}O_{2.95}$ and $SrCe_{0.9}Y_{0.1}O_{2.95}$ phases. The oxide powders that were prepared by attrition milling showed rather large particles and severe necking between particles in FE-SEM images as well as residual reactant ($BaCO_3$) and secondary phases ($SrCeO_3$ and $CeO_2$) in XRD patterns. The oxide powders prepared using ball milling showed particles under approximately 500 nm and typical XRD patterns of the $BaCe_{0.9}Y_{0.1}O_{2.95}$ and $SrCe_{0.9}Y_{0.1}O_{2.95}$ phases. Ceramic membranes of the $BaCe_{0.9}Y_{0.1}O_{2.95}$ and $SrCe_{0.9}Y_{0.1}O_{2.95}$ phases were fabricated by the aerosol deposition method using the oxide powders synthesized.

The purpose of this study was to examine changes in energy and macronutrient intakes during the premenstrual(days -10-1) and postmenstrual(days 5-14) phases. Thirty-two college female students recorded their food consumption and dietary patterns over 5 weeks from September 8 to October 12, 1997. Mean daily energy and macronutrient intakes and the percentage of energy intake from protein and carbohydrate were relatively consistent over the two menstrual cycle phases, but the energy intake from fat increased 1%(P<0.05)during the postmenstrual phase. Two different dietary patterns were identified by the shifts in energy intake between postmenstrual and premenstrual phases. Seventy five percent of subjects revealed a consistent pattern with the results of previous studies investigating food intake over the menstrual cycle, in which the premenstrual phase is associated with an increment in energy, carbohydrate, and protein intake. In contrast, energy, protein, and fat intakes increased during the postmenstrual phase in 25% of the subjects. We conclude that cyclical fluctuations in energy and macronutrient intakes occur in both postmenstrual and premenstrual dietary pattern groups across the two menstrual phased with the opposite directions.

An uterus is female reproductive tract organ that affected estrus cycle. During a various changes occur at uterus in estrus cycle, one of them is body fluids secretion be called uterine fluid. Therefore, the objective of this study was to investigate the changes of protein patterns using two-dimensional gel electrophoresis in uterus fluids during the follicular and luteal phases in estrus cycle of pigs. In changes of protein spots were confirmed during the follicular and luteal phases. The 136 spots were expressed in follicular phase, the 57 spots of them showed reproducibility. On the other hand, the 140 spots were expressed in luteal phase, the 73 spots of them showed reproducibility. Also, spots expressed in follicular phase were number 69 and 94 spots and spots expressed in luteal phase only were number 156, 157, 184~187, 190 and 191 spots. The spots which of higher expression levels in the luteal phase than in follicular phase were number 76 and 79 spots. In conclusion, the spots expressed in follicular and luteal phases were confirmed with difference levels and these differences are function of RNA resolving, protein synthesis and cytoskeletal architecture.

The stirred and thixoformed $SiC_p/AZ91HP$ Mg composites are studied on the basis of microstructural analysis using transmission electron microscopy (TEM). The products of interfacial reaction are identified as $Mg_2Si$, MgO and $Mg_{17}Al_{12}$ phases and the crystallized phases are found to be orthorhmbic $Al_6Mn$ and decagonal T phases. It is shown that $Mg_2Si$ and $Mg_{17}Al_{12}$ phases are found at the surface of $SiC_p$ and $Al_6Mn$ is found near interface and crystallized on the matrix. Phase identification is carried out by crystallographic work based on primitive cell volume, zero order Laue zone (ZOLZ) patterns and single convergent beam electron diffraction (CBED) patterns containing higher order Laue zone ring from a nanosized region.

Having a variety of good characteristics against other pattern recognition techniques, Multilayer Perceptron (MLP) has been used in wide applications. But, it is known that Error Backpropagation (EBP) algorithm which MLP uses in learning has a defect that requires relatively long leaning time. Because learning data in pattern recognition contain abundant redundancies, in order to increase learning speed it is very effective to use online-based teaming methods, which update parameters of MLP pattern by pattern. Typical online EBP algorithm applies fixed learning rate for each update of parameters. Though a large amount of speedup with online EBP can be obtained by choosing an appropriate fixed rate, fixing the rate leads to the problem that the algorithm cannot respond effectively to different leaning phases as the phases change and the learning pattern areas vary. To solve this problem, this paper defines learning as three phases and proposes a Instant Learning by Varying Rate and Skipping (ILVRS) method to reflect only necessary patterns when learning phases change. The basic concept of ILVRS is as follows. To discriminate and use necessary patterns which change as learning proceeds, (1) ILVRS uses a variable learning rate which is an error calculated from each pattern and is suppressed within a proper range, and (2) ILVRS bypasses unnecessary patterns in loaming phases. In this paper, an experimentation is conducted for speaker verification as an application of pattern recognition, and the results are presented to verify the performance of ILVRS.
