  • Background : This study presented an analysis of healthcare quality indicators using data mining and a development of decision support system for quality improvement. Method : Specifically, important factors influencing the key quality indicators were identified using a decision tree method for data mining based on 8,405 patients who discharged from a medical center during the period between December 1, 2000 and January 31, 2001. In addition, a decision support system was developed to analyze and monitor trends of these quality indicators using a Visual Basic 6.0. Guidelines and tutorial for quality improvement activities were also included in the system. Result : Among 12 selected quality indicators, decision tree analysis was performed for 3 indicators ; unscheduled readmission due to the same or related condition, unscheduled return to intensive care unit, and inpatient mortality which have a volume bigger than 100 cases during the period. The optimum range of target group in healthcare quality indicators were identified from the gain chart. Important influencing factors for these 3 indicators were: diagnosis, attribute of the disease, and age of the patient in unscheduled returns to ICU group ; and length of stay, diagnosis, and belonging department in inpatient mortality group. Conclusion : We developed a decision support system through analysis of healthcare quality indicators and data mining technique which can be effectively implemented for utilization review and quality management in a healthcare organization. In the future, further number of quality indicators should be developed to effectively support a hospital-wide Continuous Quality Improvement activity. Through these endevours, a decision support system can be developed and the newly developed decision support system should be well integrated with the hospital Order Communication System to support concurrent review, utilization review, quality and risk management.

  • Korean fishing boats have had appropriate hull forms for the safety, stability and convenience of fishing ability. However, Korean fishermen are recently concerned about the resistance performance and speed of Korean fishing boats, because the prices of fuel oil are gradually risen, also the exhausting of fish resources and the demand of high speed fishing boats are increased. Therefore, the necessity of the study on the improvement of resistance performance for Korean small coastal fishing boats is gradually increased. This study compares the hull form characteristics of Korean fishing boats with those of Japanese fishing boats, and the hull form of a representative Korean fishing boat is modified. From the modification of the hull form parameters for the Korean fishing boat, the improvement of resistance performances is evaluated. Moreover, the increase of resistance performances is also achieved from the modification of local characteristics for the hull form of the Korean fishing boat. A computational method and ship model tests in towing tank are used for the conformations of the improvement of resistance performance.

  • Exposure to the sun, ultraviolet radiation, and oxidative stress are the chief etiologic factors responsible for melasma. The ingredients of Korean red ginseng powder, which include ginsenoside and phenolic compounds, have antioxidative effects and reduce ultraviolet B-induced pigmentation. This study was designed to evaluate the effectiveness and safety of Korean red ginseng powder in patients with melasma. In 25 female patients, 3 g of Korean red ginseng powder was orally administered for a 24 week period. The level of pigmentation and erythema were determined and clinical improvement was evaluated by the melasma area and severity index (MASI), melasma quality of life scale (MELASQoL), and patient- and investigator-rated global improvement scale. After 24 weeks, the MASI score decreased from 8.8 to 5.6, and MELASQoL showed improvement in 91% of patients (p<0.05). The mean level of pigmentation decreased from 184.3 to 159.7 and erythema levels decreased from 253.6 to 216.4 (p<0.05). Additionally, 74% of the patients showed some improvement in both patient- and investigator-rated global improvement scales at week 24. Korean red ginseng powder was well tolerated by most of the patients. In conclusion, Korean red ginseng powder showed good tolerability and beneficial effects in patients with melasma. The use of Korean red ginseng would be counted as a useful adjunctive therapy for patients with melasma.

  • The purpose of this study is to analyze the school dietitian's cognition, practical use of environment-friendly agricultural products to provide fundamental information for the qualitative improvement in the school food service. The results of the study are as follows: 1. It was clearly recognized that the subsidy for the school food service is generally insufficient, the amount of additional appropriate subsidy for the school food service was different according to type of school and roughly 300~600 won in each of foods needs to be supported. 2. The environment-friendly agricultural products that were often used in the school food service were vegetables and grains. 3. In the analysis of cognition and problems toward using environment-friendly agricultural products, the dietitians recognized that environment-friendly agricultural products should be appropriately used. A reason that environment-friendly agricultural products were better than general agricultural products was composed of a use of less additive, good ingredient, and good outer condition. 4. In the analysis of countermeasure on increasing environment-friendly agricultural products in the school meal service, the response to that more additional subsidy was necessary for the school food service. The highest and the most positive effects after using environment-friendly agricultural products were students' health improvement and improvement in parents' satisfaction with the school food service.

  • 본 연구는 학교현장의 통합교육을 지원하기 위해 지역사회의 장애아동복지시설에서 실시한 통합 프로그램의 효과를 분석하였다. 지역할당을 고려한 임의표집 방식으로 선정된 초등학교 6학급의 일반아동에 대해 실험조사설계에 따라 빈도분석, T 검증, 일원분산분석, 상관분석, 이원분산분석, 그리고 공분산분석 등과 같은 통계적 분석을 사용하였다. 이와 같은 분석결과에서 다음과 같은 결론을 얻었다. 첫째로 통합 프로그램의 개입으로 인한 일반아동의 사전태도와 태도개선 간에는 유의미한 차이가 있었다. 다음으로 성별, 통합학급의 경험 유무, 학교환경은 태도개선에 영향을 미치지 않는 것으로 나타났다. 반면 학년과 종교만 태도개선에 영향을 미치는 것으로 나타났다. 그러나 학년과 종교 변수가 공변수와 상호작용효과가 나타나지 않아 공분산분석을 한 결과에서는 학년과 종교는 모두 일반아동의 태도개선에 영향을 미치지 않은 것으로 나타났다. 따라서 일반아동의 특성변인들과 무관하게 통합 프로그램은 태도개선에 유의미한 영향을 미친 것으로 검증되었다. 이와 같이 장애아동복지시설에서 학교현장의 통합교육을 지원하기 위한 통합 프로그램은 순수한 효과가 있는 것으로 나타났다. 또한 장애아동과 일반아동 간의 통합교육을 지지하는 통합프로그램은 지역사회에 기반을 둔 사회사업실천 분야에서 사회통합의 중요한 도구가 될 수 있다는 것을 보여주고 있다. 따라서 본 연구에서는 향후 학교와 지역사회 연계를 통한 통합 프로그램의 개발과 적극적인 지원이 필요하다는 것을 제안하고 있다.
