  • 본 연구는 초등학교 6학년 학생들이 기하 증가 패턴을 탐구하는 상황에서 함수적 관계를 어떻게 인식하고 일반화하며 표현하는지에 대해 분석하였다. 연구 결과, 처음에는 학생들이 그림에 의존하여 문제를 해결하는 경향을 보였으나, 후속 항들을 탐구하는 과정에서 일반화에 대한 시도가 자연스럽게 나타났다. 또한, 패턴 탐구의 결과를 어떤 방식으로 표현하는지는 개인에 따라 차이가 있었는데, 이 표현 방식은 패턴을 일반화하고 유사 상황에 적용하는 과정에도 영향을 끼쳤다. 본 연구는 이러한 결과들을 토대로, 초등학교에서의 함수적 사고의 지도 방안에 대한 시사점을 제공한다.

  • 패턴 활동은 어린 학생들의 함수적 사고를 신장하는 데 효과적이지만, 구체적으로 패턴을 어떻게 지도해야 하는가에 대한 연구는 부족한 편이다. 이에 본 연구에서는 초등학생의 함수적 사고를 신장하기 위한 기하 패턴의 지도 방안을 도출하여, 이를 초등학교 수학 수업으로 구현한 사례를 분석하였다. 이를 위하여 초등학교 4학년 3개 학급을 선정하였고, 동일한 교수 학습 과정안을 바탕으로 세 명의 초등학교 교사들이 각 학급에서 수업을 진행하였다. 수업은 크게 공통성을 인식하는 과정, 공통성에 대한 인식을 확장하는 과정, 공통성을 표현하는 과정으로 구성하였으며, 분석 결과 기하 패턴의 구조를 분석하는 활동은 초등학교 4학년 학생들이 패턴의 일반화된 규칙을 추론하고 표현하는 활동에 영향을 주었다. 이와 같은 결과를 토대로 초등학생의 함수적 사고를 신장하기 위한 기하 패턴의 지도 방안에 대하여 시사점을 논의하였다.

  • Functional urinary incontinence, the absence of any neurologic or structural abnormality as a cause of urinary incontinence in children, is one of the most common clinical problems encountered in pediatric and urologic departments, and it can be socially and emotionally distressing for the affected children. The prevalence rates of functional urinary incontinence in school-aged children are not very high and differ between boys and girls. The underlying mechanisms of functional urinary incontinence are heterogenous and can be associated with the following dysfunctions of both the storage and voiding patterns of the bladder: overactive bladder, dysfunctional voiding, lazy bladder syndrome, HinmanAllen syndrome, giggle incontinence, and vaginal voiding. Treatment methods for urinary incontinence in children should be chosen according to these clinical conditions. Treatment modalities generally consist of the treatment of comorbid conditions such as urinary infection and constipation, behavior therapy to modify learned voiding patterns, and pharmacotherapy primarily with anticholinergics and ${\alpha}$-adrenergic blockers. This review discusses the optimal treatment modalities, including treatment of the underlying voiding disorders, and diagnostic approaches related to functional urinary incontinence in children.

  • Purpose: The purpose of study was to investigate the effects of combination patterns exercise of Proprioceptive Neuromuscular Facilitation (PNF) on unstable surfaces on pain, functional disability, and fear avoidance belief in patients with chronic low back pain. Methods: Twenty four patients were assigned to either the experimental group (n=12) or the control group (n=12). Patients in the experimental group performed combination patterns exercise of PNF on unstable surfaces. Patients in the control group performed combination patterns exercise of PNF on stable surfaces. Both exercises were performed for five days per week, for a period of six weeks. Pain was measured by the Visual Analogue Scale (VAS) and University of Alabama at Birmingham (UAB). Functional disability was measured using the Oswestry Disability Index (ODI) and Roland Morris Disability Questionnaire (RMDQ). Fear avoidance belief was measured using the Fear Avoidance Beliefs Questionnaire (FABQ). A paired t-test was used for determination of differences before and after treatment, and an independent t-test was used for determination of differences between treatment groups. Results: In within group comparison, the experimental group showed statistically significant difference for all variables (p<0.05). In comparison between two groups, the experimental group showed relatively greater significant difference for all variables (p<0.05). Conclusion: Based on such results, it can be said that combination patterns exercise of PNF on unstable surfaces has an effect on pain, functional disability, and fear avoidance belief in patients with chronic low back pain.

  • Nanoimprint lithography is a next generation lithography technology, which enables to fabricate nano to micron-scale patterns through simple and low cost process. Nanoimprint lithography has been applied in various industry fields such as light emitting diodes, solar cells and display. Functional patterns, including anti-reflection moth-eye pattern, photonic crystal pattern, fabricated by nanoimprint lithography are used to improve overall efficiency of devices in that fields. For these reasons, in this study, sub-micron-scaled functional patterns were directly fabricated on Si and glass substrates by thermal imprinting process using ZnO nano-particles dispersion resin. Through the thermal imprinting process, arrays of sub-micron-scaled pillar and hole patterns were successfully fabricated on the Si and glass substrates. And then, the topography, components and optical property of the imprinted ZnO nano-particles/resin patterns are characterized by Scanning Electron Microscope, Energy-dispersive X-ray spectroscopy and UV-vis spectrometer, respectively.

  • This research was accomplished to analyze the preference and the actual using patterns of the bakery products using functional ingredients by subjects' age. This survey was examined by the self-administered questionnaire method for 374 female subjects in Suwon. All respondents preferred breads than confectionaries with functional ingredients. As for the products of cooking ingredients, cookies, roll-cake, cake, chocolate, the preference of teenagers was higher than those of the other groups. Subjects preferred potatoes, fruits, rice and green tea as functional ingredients. Over thirties showed the high preference over beans, vegetables, mushrooms, ginseng and oriental herbs while fruits were highly preferred in teenagers and twenties. The ratio of using the bakery products with functional ingredients once or twice a week was higher in over thirties than those of the other groups. Subjects answered that they generally spent $3,000won\sim5,000won$ on those products. Functionality of products was considered as the more important factor in thirties than in the other groups. The lack of information about these products and functional ingredients was reported by teenagers and twenties. These results would be basic data for marketing or improvement of baking products with functional ingredients.

  • 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.

  • Analyzing morphological evolution over a long period of time is deemed an effective way to identify problems occurring in the process of urban development, in addition to achieving a fundamental understanding of socio-cultural changes and growth rooted from the context. As far as the urban morphology is concerned, Hong Kong is characterized by its unique high-density and compact layout patterns, which have aroused the interest of a number of authors in the urban design domain. Whilst an increasing number of redevelopment projects in Hong Kong were criticized for ignoring and destroying the old urban fabric, there is a need for research to investigate the origins and changes of various urban patterns and their implications for society. By employing the theories and techniques of space syntax, this paper accordingly provides a morphological analysis based on the Wanchai District - a 'Segment-line' city, which particularly epitomizes various urban grids of Hong Kong and may have different implications for functional aspects. By axial-mapping the urban layouts of five stages of growth since 1842 and subsequently investigating their spatial and functional transformation over the past 170 years, this paper identifies a series of spatial characteristics underlying different grid patterns, as well as achieves a precise understanding of their ever changing relationship. Based on these understandings, this paper intends to provide valuable reference and guidance for upcoming spatial development in Hong Kong and other regions.
