김도훈,정유덕,김상필,심운보,Kim, Do Hun,Jeong, Yu Deok,Kim, Sang Pil,Sim, Un Bo Korean Chemical Society 2000 Bulletin of the Korean Chemical Society Vol.21 No.11

The pH effect of the precursor solution on the preparation of $LiCoO_2$ by a solution phase reaction containing malonic acid was carried out. Layered $LiCoO_2$ powders were obtained with the precursors prepared at the different pHs (4, 7, and 9) and heat-treated at $700^{\circ}C(LiCoO_2-700)$ or $850^{\circ}C(LiCoO_2-850)$ in air. pHs of the media for precursor synthesis affects the charge/discharge and electrochemical properties of the $LiCoO_2electrodes.$ Upon irrespective of pH of the precursor media, X-ray diffraction spectra recorded for $LiCoO_2-850$ powder showed higher peak intensity ratio of I(003)/I(104) than that of $LiCoO_2-700$, since the better crystallization of the former crystallized better. However, $LiCoO_2$ synthesized at pH 4 displayed an abnormal higher intensity ratio of I(003)/I(104) than those synthesized at pH 7 and 9. The surface morphology of the $LiCoO_2-850$ powders was rougher and more irregular than that of $LiCoO_2-700$ made from the precursor synthesized at pH 7 and 9. The $LiCoO_2electrodes$ prepared with the precursors synthesized at pH 7 and 9 showed a better electrochemical and charge/discharge characteristics. From the AC impedance spectroscopic experiments for the electrode made from the precursor prepared in pH 7, the chemical diffusivity of Li ions (DLi+) in $Li0.58CoO_2determined$ was 2.7 ${\times}$10-8 $cm^2s-1$. A cell composed of the $LiCoO_2-700$ cathode prepared in pH 7 with Lithium metal anode reveals an initial discharge specific capacity of 119.8 mAhg-1 at a current density of 10.0 mAg-1 between 3.5 V and 4.3 V. The full-cell composed with $LiCoO_2-700$ cathode prepared in pH 7 and the Mesocarbon Pitch-based Carbon Fiber (MPCF) anode separated by a Cellgard 2400 membrane showed a good cycleability. In addition, it was operated over 100 charge/discharge cycles and displayed an average reversible capacity of nearly 130 mAhg-1.

The objective of this study is to propose a direction for creating a memorial park for the 250 students victims of the Sewol ferry disaster. To this end, this study first attempted to understand the matters discussed at various levels to create a memorial park and find a way that the park can be built by gathering opinions from the bereaved families and the victims themselves, as well as local residents, and experts. Workshops, competitions, special lectures, and websites, etc, were analyzed. A social discourse analysis methodology was used for systematic analysis, and the analyzed discourse was categorized into 4 types for assessment, and the functions and roles were subdivided into 15 types. To assess the priorities and the adequacy of the discourse, an analytic hierarchy process (AHP) was used among 30 activists, public servants, and experts. Then, a survey was conducted to analyze the perception of the residents (467 participants including the bereaved families) about the memorial park. Based on the results of the analysis, two directions were set for the memorial park. First, is a memorial park to remember the victims in everyday life. It must be a park with various cultural contents instead of a conventional memorial park that is solemn and grave sharing anguish and sorrow. The memorial park for the Sewol ferry disaster must become a space where visitors can naturally encounter and remember the victims. Second, is a park that serves as a catalyst that brings change and innovation to the community. It must be able to bring change to the community with direct and indirect influence. It must serve as an impetus to bring change and innovation to the community in the mid-to-long-term. Having many visitors may also lead to an economic effect. These visitors may not just stay in the park, but even contribute to revitalizing the local businesses. The purpose of this study is to apply the research findings to guide the International Design Competition scheduled for 2020 and serve to establish guidelines for a continuous park management system. 세월호 참사로 희생된 250명의 아이들을 위한 추모공원 조성방향을 제안하는 것이 본 연구의 목적이다. 이를 위해 먼저 지역사회 차원에서 추모공원에 대해 논의했던 사항을 이해하고, 피해당사자인 유가족들과 지역주민, 전문가들의 의견수렴을 통해 추모공원 방안을 모색하고자 했다. 유가족들과 시민들이 함께 국제공모전 시민지침서를 만들고자 진행한 참여형 워크숍, 신진디자인의 아이디어 수렴을 위한 공모전, 인문사회·문화관광·도시재생 전문가들과 함께한 특강, 홈페이지에 게시된 반대청원 등 다양한 활동들이 전개되었다. 이들 과정을 체계적으로 분석하기 위해서 사회적 담론분석 연구방법을 활용하였고, 분석된 담론을 평가하기 위하여 4가지 범주로 유형화하고 기능 및 역할을 15가지로 세분화 했다. 이렇게 도출된 담론들의 우선순위 및 적정성 평가를 위하여 활동가, 공무원, 전문가 30명을 대상으로 계층화 분석방법(AHP)을 수행했고, 설문조사를 시행하여 세월호 유가족 포함 지역주민 467명이 생각하는 추모공원에 대한 인식을 분석했다. 그리고 분석된 연구결과를 바탕으로 세 가지 추모공원 방향을 제안했다. 첫 번째는 일상 속에서 기억하는 추모공원이다. 기존의 추모공원처럼 경건함과 엄숙함으로 아픔과 슬픔을 나누는 공간의 모습에서 탈피하여 문화적 콘텐츠가 다양한 공원이 되어야 한다는 것이다. 그리고 이러한 공원생활 속에서 희생된 아이들을 자연스럽게 만나게 되고, 기억하는 것이 나아가야 하는 방향이다. 두 번째는 지역사회의 변화와 혁신을 유도하는 촉매제와 같은 공원이다. 세월호 추모공원이 존재함에 따라 지역사회에 직·간접적인 영향으로 변화를 줄 수 있는 공간이 되어야 한다. 중장기적인 관점에서 작은 공간 하나 만드는 것을 넘어 지역사회의 변화와 혁신을 만들어가는 계기가 되어야 한다. 세 번째는 사회적 공유과정을 거쳐서 모든 이들이 함께 하는 공원이 되어야 한다는 지점이다. 도심형 메모리얼 파크가 혐오시설이라는 인식 때문에 아직도 반대하는 이들이 일부 있는데, 이들을 포용하여 함께 할 수 있는 방법을 찾는 것이 중요하다. 본 연구를 통해서 도출된 연구내용이 2021년 예정된 국제설계 공모지침서에 반영되고, 중장기적 관점에서 지속적 공원운영 관리 가이드라인 역할을 하도록 하는 것이 목적이다.

According to the increase of the proportion of aged people, the medical demand for a senile chronic disease has been increased; therefore, aged people call for a geriatric hospital for special geriatric medical service. The main purpose of this study was to analyze the general characteristics and financial status of geriatric hospitals. For the study, a questionnaire was designed and sent to the geriatric hospitals to fill out the patient statistics, number of headcount by department, etc. to find out the stability, profitability, activity and so on financial statements of the hospitals were analyzed. The major findings of this study were as below. 1. The ratio of the medical expenses to the revenue of the geriatric hospitals is much lower than acute care hospitals. But the probability of bankruptcy is higher due to the high ratio of the liabilities therefore it is required to stabilize the financial position by donating more money. 2. Government budget for the elderly people is not enough. To support the geriatric hospitals by going subsides, government should increase the budget. 3. Portion`s of the patient of the geriatric hospitals are government support patient. Since the government doesn`t pay the medical charges quickly, geriatric hospitals have a serous cash flow problem. Therefore, it is required that government is to prepay the bill. 4. Since geriatric hospitals treat elderly patient and most patients are government support patients, geriatric hospitals can be said to operate under the strict. 5. When we introduce the daily medical charge, the self-liability will be reduced on approximately 50% of current. This affection will bring a huge progressing financial structure to the medical profit of the geriatric hospital, and also patient family will feel less economical burden.

This study utilized Corpus-based Analysis process to compare the Cold Pathogen chapter in the ‘English version of 『Donguibogam』’ to the ‘English version of the 『Shanghanlun』’ translated by 罗希文 (Luo xi wen). Results of the linguistic analysis indicate that TTR, a ratio of number of types to number of tokens in the English version of 『Shanghanlun』 was 5.92% while TTR in the Cold pathogen chapter of English version of 『Donguibogam』 was 6.01%. It was also noted that the types of words frequently appearing in the two publications were the scientific name of medicinal herbs; the method of producing the herbal prescription (including terminology representing weights and measures); and Chinese descriptions of concepts considered important in both Korean and Chinese medicinal practices. Finally, it was possible to find points of comparison in naming of symptoms, diagnosis, prescriptions, and respective names of six meridians. Though the language difference is minimal, the vocabulary found in the Cold Pathogen chapter of 『Donguibogam』 was more diverse than Luo’s translation of 『Sanghanlun』. In general, literal translation in keeping with the sense of original text was better performed in Luo’s translation of the 『Sanghanlun』 whereas the English version of the Cold Pathogen chapter in the 『Donguibogam』 was more of a “free” translation.
