본 연구에서는 데이터 마이닝 기법을 활용하여 한국 프로야구의 승패예측모형을 구축하는 실험을 진행하였다. 이를 위해, 2017년에 실시된 한국 프로야구 10개 구단의 전체 경기 중 무승부 경기를 제외한 1,418경기에 대한 자료를 사용하였다. 승패예측모형에는 의사결정나무, 베이즈넷, 인공신경망 알고리즘과 앙상블 기법인 배깅과 부스팅이 사용되었으며, 그 결과 배깅 기법에 인공신경망을 적용한 예측모형에서 가장 높은 예측률인 85.18%를 기록하였다. 다음으로 의사결정나무 기반 예측모형을 활용하여 한국 프로야구 전체 구단에 관한 8개의 승패규칙을 도출하였다. 여기에서 승패규칙은 승패예측에 영향을 미치는 주요 요인들인 팀출루율, 팀타율, 피안타, 안타, 타석, 타수로 표현되며, 도출된 규칙을 바탕으로 구단의 승률 향상에 도움을 주는 전략을 제안하였다. 또한 플레이오프 진출 구단과 미진출 구단에 관한 승리규칙을 각각 4개씩 도출하였고 이를 바탕으로 두 집단에 맞춤화된 승률 향상 전략을 제시하였으며, 실제 구단에서 선수를 영입한 방향과의 비교를 통해 제시된 전략의 활용 가능성을 확인하였다. This study conducted an experiment to develop win-loss prediction models for the Korean professional baseball league using data mining techniques. To this end, we used data on 1,418 games from all games played by the ten Korean professional baseball teams in 2017, except draw games. We developed win-loss prediction models using not only a decision tree, Bayse net, and artificial neural network algorithms, but also ensemble methods, such as bagging and boosting. As a result, first, we found that the artificial neural network-based prediction model using the bagging method reported the best accuracy (85.18%). Second, we derived eight win-loss rules for entire teams from the decision tree-based prediction model. These rules consist of six influential factors: team on base average, team batting average, hit by opponent, hit, plate appearances, and at bat. Using the derived rules, we proposed helpful strategies for improving the winning rate. Third, we derived four winning rules for both playoff teams and non-playoff teams; using the rules we proposed customized strategies for improving the winning rate of the two different groups. Finally, we confirmed the feasibility of the proposed strategies by comparing non-playoff teams’ actual player recruitment strategies.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Gastric angiodysplasia is vascular ectasia in mucosa and submucosa of the gastric wall. It is an uncommon cause of upper gastrointesinal hemorrhage that may occur in the stomach or duodenum. There are many kinds of endoscopic treatments, such as argon plasma coagulation, electrocoagulation, heat probe, and submucosal injection of hypertonic saline mixed with epinephrine for gastric angiodysplasia. However, these treatment methods are associated with high rate of rebleeding. In order to avoid the recurrence, endoscopic band ligation has recently been used as an alternative method for endoscopic treatment of gastric angiodysplasia. We encountered a case of gastric angiodysplasia that presented with overt bleeding and anemia, and was successfully treated with endoscopic band ligation.

Automatic monitoring of cutting process is one of the most important technologies for increasing the stability and the reliability of unmanned manufacturing system, In this study, basic methods which use the acoustic emission (AE) signals and cutting forces were proposed to monitor flank wear (width of flank wear) quantitatively. First, in order to detect flank wear, it was investigated that the influence of cutting conditions, that is, cutting velocity, feed and depth of cut, on AE signals (AErms) and cutting forces. Futhermore, the relation between flank wear and the measured signals (AErms cutting force) was discussed.

Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

Purpose : Patients with cancer of unknown primary site represent 5% to 10% of all cancer patients. This study was to evaluate survival and prognostic factors of patients with malignancy of unknown origin. Materials and Methods : A retrospective analysis was done for one hundred and two patients with malignancy of unknown origin who were treated from January 1989 to December 1998. There were 52 male and 50 female patients. Age of patients ranged from 20 to 94 years (mean 58 years). Clinical presentation depended on the site of metastases. In cases of multiple metastatic sites, we selected the first apparent metastasis or the symptomatic one for which the patient was first seen. The three most frequent initial metastatic sites were peritoneum, lymph node, and liver. Median follow up period was 4 months(0-100 months) and survival rate measured form the time of diagnosis. Results : The two years survival rate was 13.6% with a median survival time of 4 months. The factors associated with the overall survival rate were the tumor marker CEA(p=0.0061), smoking history(p=0.0039), and histologic type(squamous cell carcinoma versus non-squamous cell carcinoma, p=0.0295). Marginal statistical difference was found according to performance status. No statistical differences were found according to sex, weight loss, initial metastatic site and numbers, primary lesion site, and treatment modality. Conclusion : Squamous cell carcinoma was associated with survival rate. In squamous cell carcinoma of unknown origin with good prognostic factor, especially cervical lymph node metastasis, we suggest an approach of extensive initial workup for staging and aggressive treatment.
