디자인문제의 조기해결을 위한 디자인 문제요소 분석 및 해결안에 관한 연구
박창해(Chang Hae Park) 한국디자인문화학회 2008 한국디자인문화학회지 Vol.14 No.3
The product is produced with development process which is various. The designing process is the first process of product development process. The design process is vary Important. The design process is the moment when it is important makes a quality of product. There is it will be able to solve multi problem elements. But, a actually it does not solve many problem from design process. In this Thesis, I present the method it will be able to solve the problem which is various from design process. First of all classified a and defined the meaning of problem element. As the Design Risk Mode defined a problem element. Secondly, it presented a Design Risk Mode element extraction process. it searches the problem which occurs and it puts out when developing the product. The Hierarchical Structure Function Analysis is one kind method for extracting Design Risk Mode. Finally, presented a Design Risk Mode Analysis Process. This process will extract a problem and it will be able to solve the Design Risk Mode. Through Design Risk Mode Analysis Process to design the products, it will be possible to appreciate the Design Risk Mode systematically and produce the Superior product, also it is expected for users to comprehend the product still better and use it more effectively.

Objectives: To investigate whether smoking and the smoking status are predictors of the incident impaired fasting glucose (IFG) or type 2 diabetes in Korean men. Methods: A cohort of 1,717 Korean men without IFG or diabetes, who underwent annual periodic health examinations for 4 years (2002-2006), were retrospectively investigated. IFG and diabetes were defined as a serum fasting glucose concentration of 100-125 mg/dL and more than 126 mg/dL, respectively. Cox's proportional hazards model was used to evaluate the association between smoking and development of IFG or type 2 diabetes. Results: A total of 558 cases (32.5%) of incident IFG and 50 cases (2.9%) of diabetes occurred. After controlling for the potential predictors of diabetes, the relative risk for IFG, compared with the never smokers, was 1.02 (95% CI=0.88 to 1.19) for the ever-smokers, 0.96 (95% CI=0.79-1.16) for those who smoked 1-9 cigarettes/d, 1.15 (95% CI=1.01 to 1.30) for those who smoked 10-19 cigarettes/d, and 1.31 (95% CI=1.10 to 1.57) for those who smoked 20 or more cigarettes/d (the P value for the current smokers was only p<0.002). The respective multivariate adjusted relative risks for type 2 diabetes, compared with the never-smokers, were 1.07 (95% CI=0.64 to 1.92), 1.47 (95% CI=0.71 to 3.04), 1.84 (95% CI=0.92-3.04), and 1.87 (95% CI=1.13-3.67), respectively (the P value for the current smokers was only p=0.004). Conclusions: The smoking status and the number of cigarettes smoked daily are associated with an increased risk for developing IFG or type 2 diabetes in Korean men.

원저 : 우리나라 성인 남성에서 혈중 감마지티피와 공복혈당장애 또는 제2형 당뇨병 발생과의 연관성
김태연 ( Tae Yeon Kim ),김도훈 ( Do Hoon Kim ),박창해 ( Chang Hae Park ),조경환 ( Kyung Hwan Cho ),이승환 ( Seung Hwan Lee ),가혁 ( Hyuk Ga ),김환철 ( Hwan Cheol Kim ) 대한당뇨병학회 2009 Diabetes and Metabolism Journal Vol.33 No.3
연구 배경: 최근 감마지티피(GGT)는 제2형 당뇨병을 비롯하여, 심혈관질환의 위험 요인, 대사증후군의 요소들과 연관이 있다고 밝혀졌다. 이에 본 연구에서는 GGT와 공복혈당장애 및 제2형 당뇨병 발생 간의 관련성을 알아보고자 하였다. 연구 방법: 인천 소재의 일개 대학병원 산업의학과에서 2003년부터 2006년까지 4회 연속적으로 반복하여 건강검진을 실시한 1,717명의 남성을 대상으로, 혈중 GGT에 따라 각각 19 IU/L 이하, 20~25 IU/L, 26~34 IU/L, 35~50 IU/L, 51 IU/L 이상과 같이 다섯 집단으로 나누어, 이에 따른 공복혈당장애 및 제2형 당뇨병 발생 위험도를 Cox`s proportional hazards model을 이용하여 구했다. 결과: 혈중 GGT와 공복혈당장애 및 제2형 당뇨병 발생간에는 강한 양의 상관관계를 보였다. 공복혈당의 경우 570명(33.2%), 제2형 당뇨병의 경우 50명(2.9%)로 총 570명의 환자가 즉 추적기간 동안 공복혈당장애 및 제2형 당뇨병이 발생한 자는 각각 570명(33.2%), 50명(2.9%)으로 총 620명 (36.1%)이었다. 모든 변수를 보정한 후, GGT 19 이하를 참고군으로 GGT 20~25 IU/L, 26~34 IU/L, 35~50 IU/L, 51 IU/L 이상에서 공복혈당장애의 발생위험도는 각각 0.99 (95% CI=0.74~1.31), 1.17 (95% CI=0.89~1.55), 1.23 (95% CI=1.02~1.63), 1.38 (95% CI=1.02~1.86)이었다(P for trend 0.015). 또한 제2형 당뇨병의 경우는 1.44 (95% CI=0.48~4.35), 1.80 (95% CI=0.62~5.24), 2.55 (95% CI=1.05~7.13), 2.58 (95% CI=1.01~7.69)이었다(P for trend 0.050). 결론: 건강한 우리나라 성인 남성에서, GGT의 비교적 낮은 정상 범위의 증가라 할지라도 향후 공복혈당장애 및 제2형 당뇨병 발생 위험도가 선형적으로 증가함을 알 수 있었다. Background: We sought to determine the association between serum gamma-glutamyltransferase (GGT) levels within the normal range and the risk for development of impaired fasting glucose (IFG) or type 2 diabetes. Methods: This retrospective cohort study spanned four years (2002~2006) with 1,717 Korean men who underwent periodic health examinations at a university hospital in Incheon, Korea and were not diagnosed with IFG or type 2 diabetes. Fasting plasma glucose levels were measured at the annual health examination. IFG and diabetes were defined as a serum fasting glucose concentration of 100~125 mg/dL and more than 126 mg/dL, respectively. Cox`s proportional hazards model was used to evaluate the association between serum GGT levels and development of IFG or type 2 diabetes. Results: There was a strong dose-response relationship between serum GGT levels and the incidence of IFG and diabetes. A total of 570 cases (33.2%) of incident IFG and 50 cases (2.9%) of diabetes were found. After controlling potential predictors, the relative risks for the incidence of IFG for GGT levels≤19, 20~25, 26~34, 35~50 and≥51 were 1.00, 0.99, 1.17, 1.23 and 1.38 respectively (P for trend 0.015), and for the incidence of diabetes were 1.00, 1.44, 1.80, 2.55 and 2.58 respectively (P for trend 0.050). Conclusion: The risk for development of IFG and type 2 diabetes increased in a dose-dependent manner as serum GGT increased within its normal range in Korean men. (Korean Diabetes J 33:215-224, 2009)
