전치부 개방 교합은 다양한 원인이 복합적으로 작용하고, 진단에 따라 효과적인 치료 계획과 적절한 유지 방법을 선택할 수 있다. 대부분의 경우 교정과 악교정 수술을 통해 안정적인 교합을 얻고, 기능과 심미를 회복한다. 하지만 전체 치열에서 심한 우식증이 있는 경우 광범위한 수복이 필요하게 되므로, 보철 수복을 통해서도 교합을 재형성할 수 있다. 본 증례는 심한 우식을 동반한 골격성 전치부 개방 교합 환자에서 안모 분석 및 진단 납형으로부터 가장 효과적인 치료로 전악 보철 수복을 선택하였다. 교합력을 균등하게 분산하고 심미적인 임시 수복물을 제작하였고, 악간 관계 평가, 혀 등 연조직의 적응, 입술과의 조화를 관찰하고 수정하였다. 충분한 기간 동안 사용한 임시 수복물을 CAD/CAM (Computer-aided design/computer-aided manufacturing)을 이용하여 단일구조 지르코니아 최종 보철물로 이행하였고, 치료 종결 후 3개월 간 주기적으로 관찰하였을 때 만족스러운 결과를 얻었다. The open bite malocclusion is a common clinical entity and has multifactorial causes. Development of effective treatment plan and management is dependent on proper diagnosis. The skeletal open bite patient requires a coordinated orthodontic and orthognathic surgical approach to achieve stable occlusion, acceptable esthetics, and improved function. But in case of open bite with severely decayed dentition, restoration in the entire dentition is necessary. Using the facial analysis and diagnostic wax-up, the most effective treatment was prosthetic rehabilitation. The provisional restorations were fabricated to satisfy esthetic and functional requirements, which result in the uniformly distributed occlusal force, anterior and canine guidance. The inter-arch relationship, labio-dental harmony, and the soft tissue aspect, which is important to estimate the longevity were evaluated. Definitive restorations of monolithic zirconia were made by replicating provisional restorations by using the latest CAD/CAM technology. They were delivered to the patient and clinical follow-up observation was satisfactory.

Objectives : This study was performed to investigate the anti-fibrogenic effect of Artemisiae Capillaris Herba on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Artemisiae Capillaris Herba extract for 24 hours. The extraction was done either with distilled water or 50% EtOH. After the treatment, cell viability, proliferation, procollagen levels and the mRNA of the collagen type 1a2 and ASMA were measured by using MTT assay, BrdU assay, RT-PCR, and Procollagen Type I C-peptide EIA Kit. Results : The viability and proliferation of the hepatic stellate cells were decreased as the concentration increased. The mRNA expression decreased consistently with the volume of the secreted procollagen with the extraction made with distilled water, which indicates the herb has inhibitory effect on fibrogenesis of the liver by regulating one of the fibrosis associated genes in transcription. However, it increased in 50% EtOH extraction, which shows that a more stable reaction is expected of the extraction made with distilled water than the extraction made with 50% EtOH. The production of procollagen was decreased by a low-concentration treatment with Artemisiae Capillaris Herba, but increased by a high concentration. It seemed that the cells were responding to Artemisiae Capillaris Herba in low- concentrations, thus producing small amounts of collagen. When the drug was administered at high enough concentration to give direct toxicity to cells, the ability of cells to produce collagen was activated, and the overproduction of collagen was observed as an undesirable results. Conclusion : These results suggest that Artemisiae Capillaris Herba is beneficial in the treatment of cirrhotic patients as well as for the patients with chronic hepatitis when extracted with water in the proper concentrations.

수학적 증명에서의 물리적 논증: 삼각형의 무게중심

김성아 ( Seong A Kim ) 경북대학교 과학교육연구소 2010 科學敎育硏究誌 Vol.34 No.1

이 논문에서는 Hanna와 Jahnke의 수학적 증명에서의 물리적 논증의 사용에 대한 주장에 동의하면서, 그들의 논문에서 취급된 무게중심의 개념을 이용한 물리적 논증을 통해 삼각형의 무게중심에 대한 증명의 예를 분석하고 보다 현실적인 모델을 제시하였다. 전통적인 수학적 논증과 비교하여 물리적 논증에 있어서 물리적 개념과 모델의 역할을 명백히 드러내고, 또한 물리적 논증을 교실에서 학생들에게 제시하고 활용해야 할 필요성에 대하여 논하였다. We agree with Hanna and Jahnke`s assertion on the use of arguments from physics in mathematical proofs and analyze their educational example of the use of arguments from physics in the proof of the center of gravity of a triangle. Moreover, we suggest practical models for the center of gravity of a triangle for the demonstration in a classroom. Comparing with the traditional mathematical arguments, the role of concepts and models from physics in arguments from physics will be clearly pointed out. Also, the necessity for arguments from physics in the classroom will be discussed in this paper.

화쟁기호학으로 본 일본 건축의 비움과 사이 공간 - 료안지(龍安寺)를 중심으로

김성아 ( Seong A Kim ) 한림대학교 일본학연구소 2021 翰林日本學 Vol.- No.39

본고는 일본 선불교 사찰 중 하나인 료안지를 화쟁기호학으로 고찰함으로써 전통 건축 공간에서 사이와 비움의 관계적 특징을 파악하고자 하였다. 신토와 선불교를 사상적 기반으로 하는 일본인의 자연관은 독특한 건축 양식을 발전시켜 왔는데, 특히 하늘, 땅, 그리고 그 사이에서 인간이 어떻게 자연의 변화에 순응하면서 조화롭게 살아갈 것인가에 대한 생각이 반영되어 있다. 이러한 특징을 고찰하기 위해서는 체(體)·상(相)·용(用) 세 개의 동위소로 분석하는 화쟁기호학이 효용적 가치를 지닌다고 보고, 이를 기반으로 료안지를 분석하였다. 이와 같이 연구한 결과, 공간에서 비움(空)은 본질(體)이며, 사이(間)는 작용(用)을 의미하는 것으로 파악되었다. 비움은 본질적이며 비가시적 특징을 가지는 데, 가시적으로 드러나게 하는 사이(間)라는 작용(用)을 통해서 공간으로 드러난다. 이러한 작용의 주체인 인간은 가시적 작용을 통하여 자연을 닮고자 하는 이상향을 드러낸다. 본 연구에서 파악하고자 하였던 사이와 비움의 관계성은 불이(不二)의 관계로 파악될 수 있었다. 체상용은 분리될 수 없는 성격을 가지므로 우리는 비움(空)과 사이(間)의 개념이 합해진 것을 ‘공간(空間)’으로 인식하고 있는 것을 알 수 있었다. 마지막으로, 상(相)은 불교의 교리에 의하면 끊임없이 변화하는 가시적인 것으로, 료안지에서는 끊임없이 변화하는 상(相)으로 나타나도록 계획된 지그재그로 된 동선, 밝음과 어둠의 변화 등으로 파악되었다. 본 연구에서는 제시된 기호학 모델은 료안지에 국한되지 않고 나아가 동양의 전통 건축 공간을 분석하는 데에 다양하게 활용될 수 있을 것으로 기대한다. This paper analyzes the spatial concept in Ryoan-ji, one of the traditional Japanese architectures in Kyoto, based on Hwajaeng semiotics. Japanese have developed a unique perception of nature based on Shinto and Zen Buddhism. Japanese architecture reflects the unique perception of how humans live in harmony as adapting to changes in nature. The studies on Japanese architecture often centered on the characteristics of emptiness and ma. In order to analyze these characteristics, Hwajaeng semiotics which analyzes three isotopes, che, sang, and yong, is considered to have practical value in interpreting the relationship between nature, humans, and architecture. As a result of this analysis, it is found that emptiness in space is essential(che) in character, and ma plays as function(yong). The subject of these actions, humans demonstrate their ideal to resemble nature through visible functions (yong). Since the essence(che) and function(yong) have an inseparable character, it can be seen that we recognize the combination of the concepts of emptiness(空) and ma(間) as space 'kukan(空間).' Finally, the countenance (sang) is visible and, according to Buddhist doctrines, is constantly changing its features. In Ryoan-ji, the countenance(sang) is identified features such as zigzag movements that plan to appear different vista and wide thread in stairs that guide to slow speed. Therefore, this study suggests a semiotic model analyze traditional architectural space and is expected to be adapted in various ways to analyze traditional architectural spaces.

사누키민구렌: 일본 카가와현 민예부흥운동

김성아(Kim, Seong A) 동북아시아문화학회 2021 동북아시아문화학회 국제학술대회 발표자료집 Vol.2021 No.10

This paper examines thes ignificance and implications of the Sanuki Minguren (people’s tool guild)Movement founded in Takamatsu, Kagawa Prefecture, Japan, which began in 1963among artists, architects, and designers working together with local craftsmen to take on regional heritage. However, this movement waned a few years later, and it was not even known how long the movement lasted. One of the most successful examples is the collaboration between Sakura Seisakusho in Kagawa and George Nakashima, an American furniture designer. This collaboration continues to these days, and the Sakura Seisakusho remains the only place in the world making Nakashima"s furniture under a license contract. This study examines the significance of short-lived association and the lingering effects in regional culture. Since there are no living figures among the main founding members in this movement, the study was conducted based on the autobiographies of Kaneko Masanori, Nagami Shinichi, and George Nakashima. As results, this paper concludes that along with the governmental support Minguren Movement started with the ideal of a sculptor Nagare Masayuki who tried to continue local heritage to contemporary. In a broad sense, Sekishozuku (stone masonry school) by a sculptor Nagare became an essential motivation to expand his ideal to crafts in general. The collaboration between Nakashima furniture and Sakura Seisakusho can be evaluated as the longest-lasting and the most successful example of Minguren movement. Although it was short-lived, Minguren movement was meaningful and some what successful in the sense that pursuing their initial goals that their product executed with the local craftsmanship were sold in Bonniers, New York. Minguren is considered the origin of Kagawa Prefecture"s art promotion, and there was a continuous movement to continue its spirit in modern times. This local cultural history remains a tourism resource and visits Kagawa Prefecture.

Understanding Art Deco Lacquer Techniques by Jean Dunand through Japanese Regional Urushi Techniques

Seong A Kim(김성아) 한국가구학회 2021 한국가구학회지 Vol.32 No.4

This paper explores Art Deco lacquer techniques by French designer Jean Dunand (1877-1942) and how his artistic intuition turned Japanese regional lacquer techniques into the new phase of French modernism. Since Dunand had learned traditional lacquer techniques from a Japanese lacquer craftsman in Paris, Seizo Sugawara, Dunand’s modernized lacquer works should be strongly related to traditional Japanese techniques. Therefore, in this research, under this premise, traditional Japanese lacquer techniques developed in each region of Japan until 1900, before Sugawara moved to France, were compared to the techniques used by Dunand. As a result of the analysis, this paper explains that the lacquer techniques used by Dunand were closely related to the techniques developed in the Tohoku regions, where the lacquer master Seizo Sugawara was originally from. Therefore, Dunand’s lacquer techniques are westernized from a visual perspective but substantially rooted in Japanese regional urushi techniques.

Purpose: This study aimed to investigate the effects of fatigue, anxiety, depression, and cognitive function on the quality of life of gastrointestinal cancer patients receiving chemotherapy. Methods: Data were collected from a total of 141 participants. The measurements used were Functional Assessment of Chronic Illness Therapy for fatigue (FACIT-F), Hospital Anxiety and Depression Scale (HADS) and Functional Assessment of Cancer Therapy for cognitive function (FACT-Cog). Results: Significant correlations were found among fatigue, anxiety, depression, cognitive function, and quality of life. The mean score of quality of life was 59.60 out of 108, and 68% of the variance in QOL was explained by fatigue, anxiety, depression, and cognitive function. Cognitive function was the most influential factor (β=.30), followed by anxiety (β=-.27), depression (β=-.24), and fatigue (β=-.18). We found that the better the cognitive function, the lower the anxiety and depression, and the lower the degree of fatigue, the higher the quality of life. Conclusion: A nursing program for managing the changes in fatigue, anxiety, depression, and cognitive function should be provided to enhance maintenance and the improvement of the quality of life for gastrointestinal cancer patients who receive chemotherapy.

작용-개인-맥락-시간 모델의 관점에서 본 초기청소년의 환경체계들과의 인지된 관계와 진로성숙도

김성아(Seong A Kim) 한국아동복지학회 2012 한국아동복지학 Vol.- No.38

본 연구의 목적은 전환으로서의 의미를 가지는 발달과정 중에 있는 초기 청소년의 발달 특성을 가장 효과적으로 설명할 것으로 기대되는 브론펜브레너의 작용-개인-맥락-시간모델(Process-Person-Context-Time, 이하 PPCT모델)에 기반하여, 청소년을 둘러싼 환경적 맥락 조건 하에서 개별 환경과의 인지된 관계가 자신의 미래지향적 특성인 진로성숙도에 미치는 영향력을 검증하는 것이다. 이러한 연구목적을 달성하기 위하여 브론펜브레너의 PPCT모델의 이론적 개요와 함께 청소년의 진로성숙도와 주요 환경체계와의 작용에 관한 선행연구를 검토하여 연구틀을 설정하고, 한국복지패널 4차년도 자료를 활용하여 연구틀을 실증적으로 분석하였다. 분석결과에 따르면, 초기청소년은 발달과정 중에서 자기 자신 뿐 아니라 가족(부모)·또래·학교(교사)·지역사회의 환경체계에 둘러싸여 있으면서 그들과의 역동적인 관계를 형성하고 있다. 초기청소년의 진로성숙도는 자아존중감·가족갈등해결/부모의 교육참여/부모의 지도감독·또래애착·교사유대감·지역사회활동 참여 등 각 체계와의 관계적 특성에 의해 통계적으로 유의미한 수준의 영향을 받으나, 모든 관계에 동시에 노출되었을 경우에는 가족(부모)과의 관계적 특성이 나머지 요인에 의해 영향력을 잃었다. 즉, 초기청소년기에 들어선 개인은 가족과 같은 비공식적 체계보다는 비교적 공식적인 환경체계에 보다 더 노출되고 영향을 받는다. 마지막으로 연구결과에 따른 시사점과 후속연구에 대한 제언을 논의하였다. The object of this study is to examine the effects of perceived relationships with environmental systems on vocational maturity of early adolescents who are in the transitional stage of development. This study is based on Bronfenbrenner`s Process-Person-Context-Time(PPCT) Model. The research model was theoretically constructed after a thorough investigation of the Bronfenbrenner`s PPCT Model, previous literature on vocational maturity of early adolescents, studies that examined the relationships between early adolescents and significant environmental systems. The research model was then empirically examined using the child supplementary survey and the household survey from the 4th wave of the Korea Welfare Panel Study. Early adolescents, who are in the process of development, are surrounded by environmental systems involving their families(parents), peers, schools (teachers), and communities, and they form the dynamic relationships with all of them. Vocational maturity of early adolescents is affected by relationships with each system, including self-esteem, resolution of family conflict, involvement of parents in their children`s education, parental supervision, peer attachment, bonds with teachers, and participation in community activities. However, the effect of family(parents), which is expected to have a strong impact on individuals in childhood, loses its statistical significance on vocational maturity when variables representing relationships with other systems are included in the analytic model. This means that individuals in early adolescence are more exposed and more affected by formal environmental systems than by informal systems such as families. Lastly, the implications from the study results and the suggestions for future research are discussed.
