천지혜,김현중 한국기초조형학회 2019 기초조형학연구 Vol.20 No.4

Outdoor play facilities in apartment complex is created pursuant to Article 55.2 of the Regulations on Housing Construction, and its functions and roles are becoming significant as the importance of child development and outdoor play is on the rise. However, rather than supporting such functions, the current amusement facilities make difficult to aid the play activities due to the formal composition of uniform and ready-made products of visual aspect. As of 2009, most of the research has been focused on quantitative aspects such as the frequency of use, utilization and management of amusement facilities, satisfaction surveys, overseas case analysis, type and number breakdowns. This study conducted a qualitative observation survey to find out whether the amusement facilities actually support the play behavior. For the method of study, after revealing the distinction from existing research through previous research analysis, based on the physical, social, and cognitive development areas of children, each of the six types of play were established for the standard of analysis. Also, the observation survey was conducted on outdoor play facilities in five apartment complexes located in Seoul Gangbuk and Gangnam, which were completed since 2015. After investigating problems of the area and arrangement of amusement facilities and relationship with the play behavior of children, the following problems were derived after the quantitative and qualitative analysis. 1)The overall layout of play space according to the playground area and arrangement of play equipments did not cause various types of children’s play. 2)Most of the playgrounds and rides were concentrated on the structure and form of physical development. 3)Most of the design of play facilities was not suitable for children's play patterns which have the characteristics of creative and modified play. As a result, this study is expected to be used as a basic data in the future for amusement facilities in the apartment complexes by identifying the status of amusement facilities that are the main subjects of play, and seeking directions to move forward. 아파트단지 옥외놀이시설은 「주택건설 등에 관한 규정 제55조의2」에 의거하여 조성된 놀이공간으로, 아동발달및 옥외놀이에 대한 중요성이 대두됨에 따라 기능 및 역할이 중요해지고 있다. 그러나 현 놀이시설은 이러한 기능을 지원하기보다는, 시각적 측면의 획일화된 기성품 위주로 이루어진 형식적인 조성으로 인해 놀이행태 지원이 어려운 환경이다. 2009년도를 기준으로 현재까지 연구된 아파트단지 옥외놀이시설과 관련된 선행연구를 살펴본 결과, 대부분의 연구는 놀이시설의 이용 빈도, 이용 및 관리 실태, 만족도 설문조사, 해외사례 분석, 종류및 개수 파악 등의 정량적 측면으로 치우쳐 있었다. 이에 본 연구는 놀이시설이 실제로 놀이행태를 지원하고 있는 실정인지에 대해 알아보고자 정성적 측면의 관찰조사를 실시하였다. 연구의 방법은 선행연구 분석을 통해 기존 연구와의 차별성을 밝힌 뒤 아동의 신체, 사회, 인지발달영역을 바탕으로 각 6개의 놀이형태를 분석의 기준으로 설정하였다. 또한 서울시 강북과 강남에 위치하며, 2015년 이후 준공된 5개소의 아파트단지 옥외놀이시설 관찰조사를 실시하였다. 놀이시설의 면적 및 배치에 대한 문제점과, 아동 놀이행태와의 관계를 조사한 뒤 정량, 정성 분석 후 다음과 같은 문제점을 도출하였다. 1)놀이터 면적과 놀이기구 배치에 따른 놀이공간의 전체레이아웃은 아동의 다양한 놀이형태를 유발하지 못하였다. 2)대부분의 놀이터와 놀이기구는 신체발달 위주의 구조와 형태로 편중되어 있었다. 3)놀이시설 디자인의 대부분은 창조적이고 변형된 놀이의 특징을갖는 아동의 놀이형태에 적합하지 못하였다. 결과적으로 본 연구는 놀이 이용의 주체가 되는 놀이시설의현황을 파악하고, 나아갈 방향을 모색함으로써 향후 아파트단지 놀이시설 계획에 대한 기초자료로 활용될 것을 기대한다.

천지혜,김태형,한미영,김나연,윤경림 대한소아청소년과학회 2015 Clinical and Experimental Pediatrics (CEP) Vol.58 No.11

Purpose: Chest pain is common in children and adolescents and is a reason for referral to pediatric cardiologists. Although most cases of chest pain in these age groups are benign and do not require treatment, timely diagnosis is important not to miss life-threatening diseases requiring prompt treatment. We investigated certain clinical characteristics that may be useful in the diagnosis of such critical diseases. Methods: Patient medical records between July 2006 and September 2013 were retrospectively examined. We included 517 patients who presented with chest pain to the Department of Pediatrics at Kyung Hee University Hospital in Gangdong. Results: Most cases of chest pain were idiopathic in origin (73.6%), followed by cases with respiratory (9.3%), musculoskeletal (8.8%), cardiac (3.8%), gastrointestinal (2.9%), and psychiatric (1.4%) causes. In 6 patients (1.2%) with air-leak syndrome including pneumothorax or pneumomediastinum, the pain was abrupt, continuous, and lasted for a short period of 1–2 days after onset in the older adolescents. Of the patients with cardiac pain, 13 had cardiac arrhythmias (65.0%), 6 had congenital heart diseases (30%), and 1 had coronary aneurysms caused by Kawasaki disease (5.0%). One patient with atrial flutter had only symptoms of syncope and chest pain. Conclusion: The abrupt, continuous chest pain of a short duration in the older children was characteristic of air-leak syndrome. In patients with pneumomediastinum, radiological diagnosis was difficult without careful examination. Combined syncope should not be neglected and further cardiac workup is essential in such patients.

천지혜(Chun, Jihye) 학습자중심교과교육학회 2016 학습자중심교과교육연구 Vol.16 No.3

‘수학 스토리텔링’에서 사용 되는 ‘스토리텔링’이라는 용어가 수학적 의사소통과 밀접한 관련이 있음에도 불구하고 이러한 ‘스토리텔링’ 학습의 근본적인 유의미성을 확인하는 이전의 연구들은 미흡한 실정이었다. 이에 본 연구에서는 수학 스토리텔링 학습에서 나타나는 수학적 의사소통을 구체적으로 살펴봄으로써 수학 스토리텔링이 갖는 본질적 의미를 확인하고자 하였다. 그리고 이를 위해 지수 로그 함수를 주제로 한 스토리텔링 수업이 진행되는 고등학교 수학 교실에서의 현장 관찰, 인터뷰, 문헌 검토 등의 자료 수집과 분석을 정성연구 하였으며, 교사와 학생 각각의 수학적 의사소통과 교사와 학생 상호간의 수학적 의사소통이 어떻게 나타나는지를 확인하였다. 연구 결과, 진행 된 스토리텔링 수업에서는 담화적요소가 가장 두드러지게 나타났으며, 이는 교사와 학생 모두가 수학적 의사소통에 관한 올바른 이해가 부족하고 스토리텔링 학습이 가지고 있는 장점들을 극대화하기 위한 연습의 기회들이 많이 부족하기 때문으로 보여진다. Although the term of storytelling which is used in the math storytelling is closely related to the mathematical communication, it has been insufficient to confirm the fundamental significance of this storytelling learning. Accordingly, this study aims to determine the intrinsic meaning of math storytelling by specifically investigating mathematical communication occurred in the math storytelling learning. For this study, the observation of the Quotes logarithm function-themed math storytelling class was performed, then the interview, the qualitative data collection, and analysis of the literature review were also conducted to identify the mathematical communication of each teacher and student, and between teachers and students. The result of this current study was that the discourse factors have been founded in the storytelling class. As such, it is assumed that both teachers and students have insufficient comprehension of mathematical communication and they have little opportunities to maximize the advantages of storytelling.

The basic subject of this thesis is to study the local community facilities in close connection to the organization of public streets that exposes social identities. In modem times where social communications between self identities are progressed into a form of social identity, it is necessary to recognize the influence of social communities and to clarify the advent, significance and the values of contemporary communal spaces. However not all communities will be analysed as the scope of this thesis will be restricted to local community spaces which clearly shows the characteristics of communities that are coherent to the surrounding public streets. In extension to the background of this thesis, the emotional factors of individuals which generates and activates local communities and the unique spatial characteristics of public spaces which make communal activities possible will be clearly defined. This thesis will also explain how approaching the target group through emotional images that creates metaphor action in individuals affect the formation and evolution of communities. Also, architectural design factors which influences creating a sale identity of public street and spatial design through emotional interaction will be analysed and embodied on the target group. In conformity of this process. "Ubiquitous Technology" is and will be a crucial tool in materializing the design factors. in conclusion, this study will be a highly intensive research in restoring the lyricism of our urban cities through experiencing the development of public street and local community centers in public districts and in finding the possibilities of utilizing community space as a mean of changing our future lifestyle.

The purpose of this study was to identify control points through microbiological hazard analysis in the manufacturing processes of starch noodles. Samples were collected from the ingredients, manufacturing processes,equipment and environment. Microbiological hazard assessments were performed using aerobic plate counts (APC), Enterobacteriaceae (EB), E. coli and five pathogens including B. cereus, E. coli O157:H7, L. monocytogenes,Salmonella spp., and S. aureus. The APC levels in raw materials were from 2.12 to 3.83 log CFU/g. The contamination levels after kneading were 4.31 log CFU/g for APCs and 2.88 log CFU/g for EB counts. APCs decreased to 1.63 log CFU/g and EB were not detected after gelatinization, but their levels slightly increased upon cooling, cutting,ripening, freezing, thawing, and separating. The reuse of cooling and coating water would be a critical source of microbial increase after cooling. After drying, APCs and EB counts decreased to 5.05 log CFU/g and 2.74 log CFU/g, respectively, and the levels were maintained to final products. These results suggest that the cooling process is a critical control point for microbiological safety, and the cooling water should be treated and controlled to prevent cross contamination by pre-requisite program.

윤송이,천지혜,이경석,나영호,최선희 대한소아감염학회 2014 Pediatric Infection and Vaccine Vol.21 No.3

Purpose: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. Methods: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. Results: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6±2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18±2.10 vs 4.79±1.49 days, P=.17) and total fever duration (5.32±2.07 vs 6.41±3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. Conclusion: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective. 목적: 본 연구는 인플루엔자 B 바이러스에 대한 oseltamivir의 효능을 알아보고자 치료군과 비치료군간의 임상적 특징의 차이를 비교하였다. 방법: 2012년 1월부터 2012년 7월까지 입원하거나 외래 진료실을 방문하여 인플루엔자 B 바이러스에 감염된 소아 환자를 대상으로 후향적으로 의무기록을 분석하였다. 결과: 인플루엔자 B 바이러스에 의한 폐렴, 급성 기관지염, 급성세기관지염, 크룹으로 진단된 72명의 평균 나이는 3.6±2.8세 였다. oseltamivir 치료군은 38명(53 %), 비치료군은 34명(47%)이었고 치료 시기를 고려하지 않았을 때 두 군의 입원 기간(4.18±2.10일 vs 4.79± 1.49일, P=.17), 총 발열 기간(5.32±2.07일 vs 6.41± 3.25일, P=.09)을 포함한 임상적 양상에 유의한 차이가 없었다. 비치료군, 48시간 이내 치료군, 48시간 이후 치료군간의 비교에서 임상적 양상에 유의한 차이가 없었다. 3세 이하의 환자들을 대상으로 두 군간의 비교에서도 유의한 차이가 없었다. 결론: Oseltamivir 복용 전 치료군과 비치료군간의 임상적 특성에서 유의한 차이를 나타내는 항목이 없어 oseltamivir의 적응증을 도출하기 어려웠으며 치료 후 임상 경과의 유의한 차이도 없었다. 그러나 투약 시점에 따른 비교에서는 발열 시작 48시간 이내에 osetamivir를 투여한 군에서 발열 기간이 감소하는 경향을 보여주었으므로 향후 투약 시기를 고려하여 연령별 분석, 인플루엔자 B 바이러스 종에 대한 분석을 포함하는 대단위 연구가 필요하다.

Branford의 기하 증명 단계에 대한 고찰

이다희,천지혜,신상욱 고려대학교 교과교육연구소 2014 교과교육연구 Vol.7 No.2

This paper introduces each step with Branford is a geometric proof-flow occurs in the present, and the proof, as explained in Branford look at the problems that overlooked when divided into three phases. First, the intuitive proof is a proven and universal generalization, mathematical proof deals with abstract math concepts through manipulation of mathematical symbols. But this seems excessive leap that takes place between the two will have. Second, the student can prove in an intuitive level but there did not reach the level of mathematical proof, if the student is able to use their certification process to a logical and rational verbal proof enough to convince others, there is the problem of whether the student to see the level of intuitive proof. In this paper, through the intuitive proof and mathematical proof as a way to compensate for this problem, termed as' intuitive mathematical proof, and the proof is intended to refine the three-phase theory of Branford geometric theory proved to step 4.

최미석,천지혜,이경석,나영호,최선희 대한소아청소년과학회 2015 Clinical and Experimental Pediatrics (CEP) Vol.58 No.12

Purpose: Information on the clinical features of lung abscess, which is uncommon in children, at hospitalization is helpful to anticipate the disease course and management. There is no report concerning lung abscess in Korean children. We aimed to identify the clinical characteristics of pediatric lung abscess and compare the difference between primary and secondary abscess groups. Methods: The medical records of 11 lung abscess patients (7 males and 4 females) from March 1998 to August 2011 at two university hospitals were retrospectively reviewed. The clinical characteristics, symptoms, underlying disease, laboratory and radiologic findings, microbiological results, and treatments were examined. Results: Six patients had underlying structural-related problems (e.g., skeletal anomalies). No immunologic or hematologic problem was recorded. The mean ages of the primary and secondary groups were 2.4 and 5.3 years, respectively, but the difference was not statistically significant. The mean length of hospital stay was similar in both groups (22.8 days vs. 21.4 days). Immunologic studies were performed in 3 patients; the results were within the normal range. Most patients had prominent leukocytosis. Seven and 4 patients had right and left lung abscess, respectively. Staphylococcus aureus, Streptococcus pneumoniae, and antimycoplasma antibodies were detected in both groups. Two patients with primary lung abscess were administered antibiotics in the absence of other procedures, while 8 underwent interventional procedures, including 5 with secondary abscess. Conclusion: The most common symptoms were fever and cough. All patients in the primary group were younger than 3 years. Structural problems were dominant. Most patients required interventional procedures and antibiotics.

이보배(Bo?Bae Lee),천지혜(Ji?Hae Chun),이석희(Suck?Hee Lee),박해룡(Hae?Ryong Park),김정미(Jung?Mi Kim),박은주(Eunju Park),이승철(Seung?Cheol Lee) 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.12

진달래 꽃 50 g에 1 L의 네 가지 용매(메탄올, 에탄올, 아세톤, 물)를 각각 가하여 추출한 다음, 농축하여 각각의 용매별 추출물을 얻었다. 이 용매별 추출물을 이용하여 진달래꽃의 항산화 활성을 조사하였다. 그 결과, 총 페놀 함량(TPC)은 물 추출물이 328.1 ㎎/g GAE로 가장 높았고, DPPH 라디칼 소거능(RSA)은 아세톤 추출물의 IC50값이 78 ㎍/mL으로 가장 낮은 값을 가지는 것으로 나타났으며, 환원력(RP)의 경우에는 메탄올, 에탄올, 아세톤 추출물의 IC50값이 각각 469, 449, 454 ㎍/mL으로 ascorbic acid(IC50: 428 ㎍/mL)와 비슷하게 높은 활성을 보임을 알 수 있었다. 그리고 산화적 DNA 손상 보호효과를 측정한 결과 메탄올과 아세톤 추출물은 1 ㎍/mL에서 50 ㎍/mL의 농도로 처리한 결과 유의적으로 DNA 손상정도가 감소하였고, 물 추출물의 경우에는 5 ㎍/mL 처리구부터 음성대조구의 DNA 손상정도와 비슷한 DNA 손상 보호효과를 보여주었다. 따라서 진달래 꽃 추출물이 천연 항산화제로서의 잠재적 가능성을 가지고 있음을 알 수 있었다. The present study describes the preliminary evaluation of antioxidant activities and antigenotoxic effect of Rhododendron mucromulatum Turcz. flowers (RMF). The samples were prepared by extracting RMF with four different solvents (methanol, ethanol, acetone, and water), and antioxidant properties were evaluated by determining total phenolic contents (TPC), DPPH radical scavenging activity (RSA), and reducing power (RP). Water extract showed the highest total phenol content (328.1 ㎎/g gallic acid equivalents). Acetone extract showed the most potent RSA and RP. The IC50 for RSA and RP in the acetone extract were 78 ㎎/mL and 454 ㎎/mL, respectively. The 200 mM H₂O₂induced DNA damage, measured by Comet assay, was inhibited with water, methanol and acetone extract in dose dependent manner in human leukocytes. The inhibition rates were 42, 62, and 52% at the concentrations of 50 ㎎/mL of water, methanol and acetone extracts, respectively. These results suggest that R. mucromulatum Turcz. has significant antioxidative activity and protective effect against oxidative DNA damage.
