Terminal cancer patients in Korea have increased due to the development of technology and the structural change of diseases resulted from life quality improvement. Following this trend many hospitals are making efforts, such as renovating hospice wards, but architectural criteria are not sufficiently suggested for specialized hospice wards. The purpose of this study is to present the research data to improve the quality of hospice ward in general hospital Data collecting skills such as drawing documents analysis, observation were used to examine the condition of hospice ward. And, case study method was used to generate the design data which can be used for the appropriate spatial composition and the area calculation.

거래량 기준 정보거래확률 모형과 정보비대칭에 관한 연구
강성창 ( Sungchang Kang ),김주철 ( Joocheol Kim ) 한국금융공학회 2018 금융공학연구 Vol.17 No.2
본 연구의 목적은 2016년 한해 KOSPI200 선물지수와 KOSDAQ150 선물지수의 대표적인 주가폭락 상황을 정보비대칭과 유동성 수준에 대한 가설을 토대로 주가폭락의 조기경보지표로서 거래량 기준 정보거래확률 모형(Volume-Synchronized Probability of Informed Trading, VPIN)의 효과성을 검증하는 것이다. 연구 결과, 정보비대칭이 높은 상황에서는 KOSPI200 선물지수와 KOSDAQ150 선물지수 둘 다 주가폭락 사전징후가 포착되어 VPIN모형이 조기경보지표로서 효과가 있음을 확인하였다. 반면, 정보비대칭이 낮은 상황에서는 주가폭락 요인이 매수/매도 호가차이(bid/ask spread)에 신속히 반영되어 VPIN모형을 통해 주가폭락 사전징후를 파악할 수 없는 경우도 있었다. 하지만, 시장참여자들이 가격방어를 시도하는 경우 유동성이 풍부한 KOSPI200 선물지수에서는 주가폭락 사전징후를 VPIN모형을 통해 확인할 수 있었던 반면, 비교적 유동성이 낮은 KOSDAQ150 선물지수에서는 VPIN모형을 통해 주가폭락 징후를 파악할 수 없었다. 또한, KOSPI200 선물지수에서는 2016년 한해 VPIN이 일정 수준을 초과하면 주가폭락 가능성을 예측할 수 있었던 반면, KOSDAQ150 선물지수는 9월말 제약업체의 대형 악재와 11월초 트럼프 대통령 당선이라는 악재로 인하여 VPIN 수준이 급등하여 단기폭락에 대한 조기경보지표로서의 효과를 확인하기 어려웠다. 하지만, 이를 통해 VPIN 모형이 단기간의 주가폭락 가능성뿐만 아니라, 장기간의 주가폭락에 대한 모니터링 지표로서 활용될 수 있음을 시사하였다. This study has a purpose that through Volume-Synchronized Probability of Informed Trading (VPIN), which is measured value of probability of informed trading, it is to verify effectiveness of VPIN as an early warning indicator of stock market crashes by using representative stock market crashes that recorded short-term bottom point of KOSPI200 futures index and KOSDAQ150 futures index in 2016, based on hypotheses of information asymmetry and liquidity level. Also, this study analyzed time variable correlation coefficient between VPIN and futures index, verified trends and structural changes of VPIN, and analyzed significant matters of KOSDAQ150 futures index in order to research general effects of the VPIN in 2016. As the results of researches, when the information asymmetry is high, VPIN showed preliminary signs of stock market crashes in both KOSPI200 futures index and KOSDAQ150 futures index, so that this study could find that VPIN would be effective as an early warning indicator. On the other hand, when the information asymmetry is low, information that could cause stock market crashes would be quickly reflected into bid-ask spread of selling-buying so that there have been some cases that could not identify preliminary signs of stock market crashes through VPIN.

The purpose of this study is to prove the effectiveness of professional maintenance care to the periodontal disease by non-surgical approach with the toothpick method to improve the periodontal health. The patients of this study were composed of 46 patients(18 men and 28 women and mean age-50.6 yrs), suffering from chronic adult periodontitis, who had visited the department of preventive dentistry(Chosun, Univ, dental hospital, Kwang-ju city). All of the subjects were over 40 years old and be treated just by non-surgical method, Professional maintenance care using the toothpick method was performed every 3 months, and evaluations were also done after 1, 2, and 3 year- professional maintenance care based on the indices such as plaque index(O' Leary index), periodontal probing pocket depth, bleeding on probing, tooth mobility, the number of tooth loss, and the rate of tooth loss representing the state of periodontal health. Results are as follows ; 1. The longer the maintenance care, the more the effectiveness of controlling plaque, The rate of decrease in the dental plaque index was 1.5%, 4.2%, and 6.5% in 1, 2, and 3 year maintenance groups respectively(P>0.05). 2. The periodontal pocket depth decreased depends on the severity of periodontal pocket depth in all groups the maintenance years (P<0.05). 3. On the evaluation of the bleeding tendency on probing, there was a significant difference in 1 year-maintenance group(P<0.05), but the other groups did not show any difference statistically(P>0.05). 4. Tooth mobility has decreased in the maintenance years, but did not show any difference statistically(P>0.05). 5. The number and the rate of tooth loss among the patients of 1 year-maintenance group was 0.38, 1.44% respectively and that of 3 year-maintenance group was 0.44, 1.73% each. In conclusion, the results of this study mentioned above suggest that professional maintenance care should be operated effectively to prevent and to maintain the periodontal disease systematically on the purpose of improving the quality of life, and that it could be applied to the medical insurance system in order to try to make the most of the adult oral health care positively.
