This study has researched Korean casino companies, which are currently experiencing significant changes in business environments, through financial ratio analysis to understand their financial characteristics and to suggest practical implications for their future business strategies. To achieve this purpose, five years average financial ratios of three casino companies listed on the Korea Stock Exchange were compared with those of manufacturing and service industries and derived their financial characteristics from their intrinsic and operational attributes by themselves. The result shows that Korean casino companies boast higher profitability, stability and productivity than those of manufacturing and service industries, but similar in growth and lower in activity and distribution. Among three companies, P company, a privately owned and devoted to foreign gamblers, shows low profitability, stability, productivity and activity compared with other casino companies. K company, a publicly owned and mainly devoted to native gamblers, reveals low growth, activity and distribution. G company, a publicly owned and devoted to foreign gamblers, marks low distribution. Through analysis, this paper suggests followings. First, Korean casino companies need to prepare future investment by increasing ratio of retained income. Secondly, they should initiate new businesses having synergy effects and dispose of unprofitable assets to boost growth and activity. Finally, a private company has to benchmark a public company to retrench expenses and improve cost structure for raising profitability and productivity.

Lipoleiomyoma of the uterus is extremely rare and consists of mixed smooth muscle and adipose cells. 91% of the patients are 40 years of age or older. Lipoleiomyomas occur in the cervix but more frequently in the corpus uteri, as submucous, subserosal, or most commonly intramural growth. Uterine fatty tumors are almost uniformly described as benign, but malignant tumors which contain fatty tissue occur and have been described as liposarcoma. Occasionally the clinical presentation or macroscopic appearance may mimic a sarcoma and their diagnosis is made postoperatively in most cases. The histogenesis of this tumor is not clear. Histologically, it was mostly composed of mature fatty tissue intermingled with small amount of fibrous and smooth muscle components in an irregularly reticular pattern.

본 연구의 목적은 회원제 골프장 기업의 부도예측 모형을 개발하여 회원제 골프장 기업의 의사결정자에게 실무적인 도움을 주고자 하는 것이다. 본 연구의 분석을 위하여 22개의 회원제골프장 부도기업과 22개의 정상기업을 선정하였으며, 분석방법은 다변량판별분석과 로지스틱회귀분석을 활용하였다. 분석결과 차입금의존도, 총자산회전율, 총자산순이익률, 자기자본회전율, 유형자산회전율, 자기자본 비율이 유의한 변수로 선정되었다. 이 중 부도에 영향을 미치는 중요한 변수는 총자산순이익률과 총자산회전율이다. 부도 회원제골프장의 경우 과도한 투자와 다양한 회원혜택에 따른 수익성 악화로 인하여 총자산회전율과 총자산순이익률이 낮게 나타나고 있다. 따라서 회원제 골프장 기업은 적정한 투자와 자기자본으로 골프장 건설에 착수해야 하며, 수익성 개선을 위한 노력을 기울여야 한다. The purpose of this study is to develop a bankruptcy prediction model for membership golf course companies as a betterment to decision maker. A sample of 22 bankrupt membership golf course companies and 22 non-bankrupt membership golf course companies were selected for analysis. The analysis was conducted through multivariate discriminant analysis and logistic regression analysis. The result criterion were determined to be: Total borrowings and bonds payable to total assets, total assets turnover, net income to total assets, stockholders’ equity turnover, tangible assets turnover, and stockholders’ equity to total assets. The most effective variables at predicting bankruptcy were net income to total assets and total assets turnover. The findings showed that bankrupt membership golf course companies tended to have low total assets turnover and net income to total assets; this was attributed to excessive investments and decreasing profitability as a result of various members’ benefits. Therefore, it is recommended that membership golf course companies have to start construction with optimal investment and equity levels as well as increasing profitability.

Intramural implantation is among the rarest forms of ectopic pregnancy.Since the first description by Perli, 21 cases were reported in worldwide literatures.The pathologic criteria required for intramural pregnancy is that the product of conception is completely surrounded by uterine musculature and is separated from the uterine cavity and the fallopian tube or round ligament.The previous history of uterine injury or adenomyosis is known as possible etiology of intramural implantation. Because the early diagnosis is very difficult, most cases is found after onset of complication such as a uterine rupture or hemoperitoneum. We have recently experienced a case of intramural pregnancy diagnosed and treated by laparoscopy in a 9 weeks gestation nulliparous woman without previous history of uterine injury or disease, and report with a brief review of literatures.

본 연구는 서부 호주의 Durokoppin 자연 보호 구역에 서식하고 있는 흰개미에 의해 수확되어 개미집에 저장되어 있는 식물유체와 영양물질 함량을 조사하기 위해 수행되었다. 개미집에 저장된 식물유체의 경우 두 조사지역간의 유의적 차이는 없었으며, 개미집에 저장된 식물유체를 분류한 결과 잎과 가지 등 7가지 종류의 식물 유체로 확인되었다. 개미집 내 저장된 식물유체의 영양물질 함량은 유의적 차이는 없었지만 shrubland 보다 Woodland가 높았으며, 영양물질 총량 역시 shrubland보다 Woodland가 많았다. 연구결과를 종합해 보면 흰개미는 조사지역에서 다양한 종류의 식물유체를 수확하여 이용하고 있으며, 조사지역내 토양 유기물 함량이 적은 점을 고려할 때 생태계 영양물질 순환에 있어서 중요한 역할을 하고 있는 것으로 사료된다. This study estimated the mound litter biomass and the nutrient content of mound litter in the two study plots in Durokoppin Nature Reserve, Western Australia between 2004 and 2005. There were no significant differences in biomass of litter in individual mounds between the two study plots. Seven components of litter were found in the mounds. The nutrient concentrations were higher in the wood-land than in the shrubland plot, although the differences were not statistically tested, and the total amount of each nutrient measured was generally greater in the woodland than in the shrubland plot. The aforementioned results show that D. tamminensis harvests various plant material according to bio-mass availability. The role of this termite takes on particular importance in view of the fact that Western Australian soils are notoriously impoverished in nutrients.

The multicystic dysplastic kidney is extreme type of dysplastic kidney and the most frequent cause of neonatal abdominal masses which were found by prenatal ultrasonography. Recently in Korea, diagnosis of multicystic kidney is increasing as prenatal ultrasonography becomes more popular. In congenital megacolon, which is the term often applied to Hirschsprung`s disease, colonic dilatation results from functional obstruction owing to congenital absence of the intramural and submucosal neural plexuses. Unilateral multicystic kidney with congenital megacolon is rare case of congenital anomalies and associated with urinary tract and other anomalies. Herein, we report a case of left multicystic kidney combined with congenital megacolon based on clinical and radiological and pathological findings.

지수귀문도는 18세기 조선 학자 최석정이 고안한 조합 퍼즐이다. 마방진처럼 특정 부분의 합이 같도록 숫자를 배열하는 문제이지만, 배열 모양이 육각형 형태이다. 특정 형태의 지수귀문도는 풀이법이 알려져 있지만, 일반적인 형태의 해는 찾기가 어렵다. 그래서 조합검색 기법을 시험하는 데 좋은 문제이다. 이 논문은 제약 프로그래밍 기법을 이용하여 지금까지 알려진 것보다 훨씬 큰 지수귀문도의 해를 찾아내는 방법을 소개한다. 그리고 순수 제약 프로그래밍만으로는 한계에 부딪칠 수 밖에 없는 이유를 논의하고, 여기에 기계 학습법을 조합하는 연구 방향을 제시한다. The hexagonal tortoise (jisuguimundo) is an 18th century Korean combinatorial problem. As in magic square problems, it requires allocating numbers to a tiling, in such a way that specific sums are conserved. Unlike magic squares, however, the tiling is hexagonal. While general solutions for some very specific shapes of tilings are known, in general they are difficult to find, so that the problem becomes a useful playground for combinatorial search methods. We present constraint programming methods which have been able to find solutions an order of magnitude larger than previous methods. We discuss why it will be difficult to extend pure constraint programming methods much further, and propose a research direction combining constraint programming and learning methods.

Objective: To evaluate the role of C-reactive protein as a predictor of infectious morbidity with premature rupture of membranes. Study Design: The study group was comprised of seventy patients who presented to the Taegu Fatima Hospital between 24∼36 gestational weeks who had a diagnosis of ruptured membranes. The study group underwent assay of C-reactive protein in the maternal serum, and divided into two groups by the results of CRP, that is 52 cases of CRP negative PROM patients (group I), 18 cases of CRP positive PROM patients (group II), and 20 cases of intact membranes women as a control group. Outcome measures were the occurrence of preterm delivery, the admission-to-delivery interval, maternal characteristics, fetal body weight, 1min & 5min Apgar score, perinatal morbidity and mortality etc. Statistical analyses were performed by means of ANOVA test and Dunnett`s T-test. Results: 1. The prevalence of positive C-reactive protein in premature rupture of membranes was 74.3%. 2. There were no significant differences of age, parity, gestational weeks at admission between group I, II and control group. 3. White blood cell count of group I, II were significantly higher than that of control group. 4. The delay of time from admission to delivery in group I, II were significantly shorter than that of control group. 5. In perinatal outcomes, the mean birth weight, 1 min/5 min Apgar score of group I, II were significantly lower than those of control group, and perinatal morbidity and mortality of group I, II were significantly higher than those of control group. 6. Chorioamnionitis was found in 6 cases of premature rupture of membranes and the sensitivity and specificity of CRP as a test to predict of pathological placental infection were 83% and 80%. Conclusion: C-reactive protein level is a very sensitive predictor of infectious morbidity in premature rupture of membranes.

미생물 제제의 실내 pot 실험을 통한 효능 실험에서 선발된 Monacrosporium thaumasium 을 이용한 KBC3017 제제의 실외 포장 실험을 통해 최적의 구성과 효능 조건을 찾았다. 선발된 균주의 미생물제제 제조를 위해 첨가한 첨가제 중 무기증량제로 Diatomite와 유기증량제로 생옥분이 효과적이었으며, 처리량별 선충 밀도 억제효과는 처리량이 많을수록 효과가 높았으나, 적정 처리량은 2%의 diatomite와 옥가루가 포함된 KBC3017 제제를 이용하여 방제하였을 때 71%의 선충 방제 효과가 나타났다. 이 방제가는 대조구와 비교하였을 때 뿌리와 줄기에서 보다 좋은 효과가 있었다. The created microbial pesticide was used to examine its effects using the inside-pot test method. The selected microbial pesticide KBC3017 particle pesticide manufactured by using Monacrosporium thaumasium was used in the farm-house outdoor test to find the optimum consistency and its effects. The more amount used, the better effect it showed. However, the optimum consistency was 2% and the KBC3017 particle pesticide for which the diatomite and raw jade powder were used as an increaser, when used 2% level of the total amount of soil, showed 71% effect on nematode prevention. The root and the stem of crops were better compared to those without any pesticide used.
