Objective Under the second term 10 year national cancer control plan is that the Ministry of Health, Welfare, and Family Affairs has been supporting hospice and palliative care for the terminal cancer patients and their families since 2005. Even though the number of care beds has doubled, it is not known whether there is a significant disparity in the access of palliative care across the regions. Methods : Palliative care beds sufficiency rates for 9 different regions were calculated by dividing the number of palliative care beds by the number of people in that area. 50 beds per 1,000,000 population was regarded as meeting the requirements, indicating 100% sufficiency rate. The inter-quartile range was used as an indicator for the magnitude of regional variations in palliative care beds supply. Results There was significant regional variation across the 9 different regions, with the range of 0% to 99.9% as of 2009. Since implementation of a support program in 2005, the median sufficiency rate has increased from 7.6% to 20.0%, however, inter-quartile range also has increased from 16.1% to 21.9%, this indicates increasing regional variations in palliative care beds supply. Conclusion : Inequality in access to hospice and palliative care is an important public health issue in terms of both meeting palliative care needs of terminal cancer patients and their families, and the efficient use of healthcare resources. Public health policies to ensure the equitable access to hospice and palliative care in every region are needed.

도가와 융의 사상으로 본 우르술라 르 귄의『어스시의 마법사』

황은주 ( Eun Ju Hwang ) 건국대학교 동화와번역연구소 2012 동화와 번역 Vol.24 No.-

본 논문은 우르술라 K. 르 귄의 어스시 3부작 중 첫 부분인 『어스시의 마법사』를 도가사상과 칼 융의 그림자 및 전일성 이론을 토대로 분석한 것이다. 초월 적인 도가 사상의 특성으로 인해 그 이론을 체계적으로 조직화하기는 어렵지만, 기본적으로 도가 사상의 목적은 도의 상태를 달성하는 것, 또는 우주의 이치와 흐 름을 경험하고 이해하는 것이라 할 수 있다. 도가 사상의 가장 큰 가치인 자제력 과 무행위에 대한 강조는 『어스시의 마법사』에서 주인공인 게드가 마법을 배우는 과정을 통해 반복하여 드러난다. 도가 사상과 융의 이론을 바탕으로 하여, 본 연구는 게드의 적을 융의 그림자로 해석하고, 게드가 마법학교의 학생으로서 받는 교 육을 침묵과 무행위라는 도가적인 가르침으로 간주한다. 본 연구는 크게 네 부분으로 나누어지는데, 첫째, 작가인 르 귄과 소설의 배경, 둘째, 작품 내 드러난 융의 그림자 이론과 도가 사상의 균형에 관한 연구, 셋째, 신화적인 화법에 관한 연구, 넷째, 작품에 나타난 성장소설의 요소 분석이다. 작품 의 줄거리는 호머나 버질의 서사시에서 사용이 되는 대서사적인 화법과 구조를 따 라 진행이 된다. 『어스시의 마법사』가 서사적인 구조를 따르고 있기는 하나 주인공 게드는 그리스, 로마 신화의 슈퍼영웅이 아니라 오히려 반영웅으로 묘사된다. 따라서 게드가 경험하는 모험은 개인적인 명예나 영광을 추구하기 위해서 시작된 것이 아니라, 자신의 실수와 무지에 의해 어쩔 수 없이 시작된다. 본 연구는 자신 의 적뿐만 아니라 자신의 진정한 정체성을 발견하고자 하는 게드의 노력을 융의 이론과 도가 사상에서 공통적으로 말하는 전일성을 추구하고자 하는 노력으로 규정하고, 전일성을 추구하는 과정을 통해 게드가 청소년에서 어른으로 성공적으로 성장했음을 보인다. This essay analysed Ursula K. Le Guin`s A Wizard of Earthsea(1968), which is the first part of Earthsea Trilogy in the frame of Taoism and Jungian theories such as shadow and wholeness. Although Taoism is a transcendental philosophy whose doctrine is not systematically organised, its main goal is to understand the state of Tao, the flow of the universe. The values of Taoism such as self-control and non-action are repeatedly taught as Ged learns magic. In the context of Taoism and Jungian theories, this essay defines the unknown enemy as the Jungian shadow and the education Ged as a young magic student receives Taoist lessons of silence and non-action. This research is divided into four parts: background to fiction and the author, Jungian shadow and Taoist balance shown in the fiction, the mythopoetic narrative, and characteristics of a Bildungsroman, or a coming-of-age novel. The plot of the novel follows structures of the epic narrative which is seen in Homer or Virgil. Although it follows the epic structure, Ged is not depicted as a super hero, but rather anti-hero whose adventure is not initiated by personal glory or honour, but by his mistake and ignorance. In this essay, Ged`s struggle to discover the true identity of his enemy - and also his - is considered as a psychic journey to achieve the Jungian/Taoist wholeness, and at the same it is considered that Ged made a successful transformation from adolescence into adulthood.

Two polysaccharides, ACP-UMF and ACP-ULF, were purified from the aerial part of Artemisia capillaris by anion-exchange chromatography, ultrafiltration, and gel filtration chromatorgraphy. The polysaccharides appeared to be homogenious from the results of HPLC. The molecular weights of ACP-UMF and ACP-ULF were estimated to be 16305.92 D and 3292.23 D, respectively, by MALDI-TOF MS. The sugar compositions were determined by GC to be arabinose 10.05%, xylose 1.67%, mannose 5.45%, galactose 39.06%, glucose 15.43% for ACP-UMF and arabinose 11.60%, xylose 11.15%, mannose 6.37%, galactose 32.47%, glucose 18.35% for ACP-ULF. A polysaccharide, SP-M, was also purified from Artemisia sylvatica in the same manner as in A. capillaris. The molecular weight of SP-M was determined to be 2462.52 D by MALDI-TOF MS. SP-M consisted mainly of rhamnose 36.49%, arabinose 29.00%, and glucose 19.38%. Incubation of CCl4-intoxicated hepatocytes with ACP-UMF reduced the levels of glutamic pyruvic transaminase(GPT) and cellular malondialdehyde(MDA) to 62.8% and 23.8%. ACP-ULF also reduced the levels of GPT and MDA to 46.1% and 38.1% and SP-M to 38.8% and 26.3%, respectively.

In this study, a severe mental retardation child who is integrated into second grade of W elementary school in Suwon was investigated to find out the effect of language training using visual images on receptive language ability. As a single case experiment, this study was designed with language training using visual images as an independent variable and the effect on receptive language ability as a dependent variable. Receptive vocabulary test and sentence comprehension test were used as test instruments and relation between a preliminary and post test was analyzed with anecdotal records and communication observation records. The training was applied to for five sessions a week and totally twenty-two sessions and observation combined with the training every four sessions. To conclude, vocabulary acquisition and sentence comprehension ability of the severe mental retardation child in the post test was meaningfully improved after applying the language training with visual images. Furthermore, receptive language ability improvement influenced communication ability of the severe mental retardation child. Therefore, it is considered that the language training with visual images is effective on the training for language capability of the severe mental retardation child.

퍼지 슬라이딩 모드의 속도 향상을 위한 제어기 설계

본 논문에서는 두 개의 시스템으로 구성된 적응 퍼지 슬라이딩 모드 제어기의 설계를 제안한다. 제안한 슬라이딩 모드 제어기는 두 개의시스템입력으로 구성된다. 기존의 슬라이딩 모드 제어기는 approximationu(t)에 불연속항 sgn함수나 sat함수를 추가하여 상태궤적을 sliding surface로 보내는 제어 기법을 사용하고 있다. 본 논문에서는 이러한 기존의 제어기에 또 하나의 불연속항 제어기를 추가하여 불확실한 제어 이득에 의한 disturbance를 줄여주고, 불확실한 외란에 강인한 제어기설계와 알지 못하는 실제 비선형 시스템과 퍼지 시스템 간의 오차에 의한 불안정성도 해결할 수 있는 제어기를 제안하였다. 또한 본 논문에서는 Fuzzy tuning을 통해 슬라이딩 조건을 가변화함으로써 기존의 슬라이딩 모드 제어기에 비해 빠르고 정확하게 추종 가능하도록 제어기의 성능을 향상시킨다. 기존의 슬라이딩 모드 제어방식에서는 ŋ값을 임의의 양의 상수로 두고 설계를 하였다. 하지만 이러한 방식은 높은 overshoot를 발생하게 하거나 늦은 정정시간을 갖게 하였다. 이를 해결하기 위하여 본 논문에서는 state의 각 상황에 맞는 ŋ값을 fuzzy tuning을 통하여 유도해 내어 overshoot를 줄이며 동시에 정정시간도 줄여 제어성능을 높이는 방법을 제안한다. In this paper, the adaptive fuzzy sliding mode controller with two systems is designed. The existing sliding mode controller used to approximation u(t) with discrete sgn function and sat function for keeping the state trajectories on the sliding surface[1]. The proposed controller decrease the disturbance for uncertain control gain and This paper is concerned with an Adaptive Fuzzy Sliding Mode Control(AFSMC) that the fuzzy systems are used to approximate the unknown functions of nonlinear system. In the adaptive fuzzy system, we adopt the adaptive law to approximate the dynamics of the nonlinear plant and to adjust the parameters of AFSMC. The stability of the suggested control system is proved via Lyapunov stability theorem, and convergence and robustness properties are demonstrated. Futhermore, fuzzy tuning improve tracking abilities by changing some sliding conditions. In the traditional sliding mode control, ŋ is a positive constant. The increase of ŋ has led to a significant decrease in the rise time. However, this has resulted in higher overshoot. Therefore the proposed ŋ tuning AFSMC improve the performances, so that the controller can track the trajectories faster and more exactly than ordinary controller. The simulation results demonstrate that the performance is improved and the system also exhibits stability.

도시 공간의 교육환경 격차에 대한 연구

황은주(Hwang Eun-Ju) 한국도시행정학회 2008 도시 행정 학보 Vol.21 No.3

The purpose of the present study is to discover how the spatial features of the educationalenv ironment patterns (educational activity, education facility, and related environment and space) found in urban space are understood as constituent components of the city. For this purpose, the study explored educational facilities relating to learning activities (students' homes, schools, and academic institutes) and the physical distribution of harmful facilities as found in Cheongju city. Also, by offering three categories of the educational features observable in an urban area and then applying them, this paper has sought to understand the city from the perspective of education. There are three key perspectives delineated throughout this study in reference to educational environment patterns, and they are as follows. 1. A student's commuting distance from home to school signifies the equity of public educational environment or utilization of facilities, because it serves as an index of public educational environment, which is a value determined by the physical location of public facilities like a school. 2. The distance from a student's home or school to a private academic institute is explained as an index of private educational environment. This is also an index that is explained by the consumer choice as made in the educational market and at the same time, implies the accessibility of private educational environment. 3. This also means that the index for harmful educational environment is defined according to how such an environment or a facility as specified by the Basic School Act is distributed around the home or school and refers to the educational viability of such a facility. From this point of view, the present study is significant because it discovers different features in terms of educational environment patterns among each regions of Cheongju city and offers a methodology that enables reciprocal comparison between regional cities and cities found in the greater Seoul area, provincial cities and cities in the greater Seoul area, and two separate districts in the same capital city.

매티슨의 『줄어드는 남자』에 나타난 1950년대 남성성의 위기와 상상적 해결

황은주 ( Eun Ju Hwang ) 미국소설학회(구 한국호손학회) 2014 미국소설 Vol.21 No.2

This essay illustrates how the unique narrative structure of Richard Matheson`s The Shrinking Man reflects the confusion, anxiety, and fear of what William Whyte Jr. referred to as the “organization man.” According to this concept, men in the 1950s were guided by two oppositional ethics?the “protestant,” individualistic ethic and the “social,” group-oriented ethic. While the protestant tradition still valorized the myth of the self-made man, conformity dictated their everyday lives. Man had to prove his masculinity through financial success, but at the same time they were expected to be family-oriented, kind, and understanding?to have traditionally “feminine” qualities. The Shrinking Man is Matheson`s sarcastic but not unsympathetic commentary on the organization man`s attempt to find imaginary solutions to his perceived masculinity in crisis. In the first part of the essay, the double structure of the novel?a narrative of the past, from week 1 to week 64, and a narrative of the present, the week 72?is examined in relation to these separate spaces. The narrative of the past shows Scott`s conformist life on the surface, while the narrative of the present reveals his subterranean life where he fulfills his individualistic, masculine dream. The structure helps the novel keep its distance from Scott Carey`s “heroic” achievement in the basement and underlines the irony in his reclaimed masculinity, which is considered in the second part of the essay.
