The consistency principle is the core design method used in design processes. Consistency is classified under four heads and these are internal consistency, functional consistency, external consistency, and aesthetic consistency. Internal and functional consistencies can be used for making a product and brand more efficient and intuitive. On the other hand, external and aesthetic consistencies are more related to the making of product and brand look as if they are in a ‘family’ of some sort. This would provide a chance to make loyal customers. For this reason, I tried to create a ‘design language system’under the consistency principle and that is the goal from this study. This case study is a series of the developments of product design processes based on the principle of consistency from 2012 to 2014. This series of developments were industrial products and were planned, developed, and manufactured by two branch branded products under mother company. These products share similar engineering technology but still have big differences between brands which are their business environments, users, and using methods. Even though they have very identical differences, we had to make these two branded products designed under a corporation brand image and to also have them be produced with a consistent and intuitive usability in order to create loyal customers in the future. In order to achieve the above goal, ‘the consistency principle’is used under a design process‘Design Language System’. 일관성 법칙에는 내부적 일관성, 기능적 일관성, 외부적 일관성, 미학적 일관성 이렇게 크게 4 가지로 분류되는데 내부적, 기능적 일관성은 사용자로 하여금 하나의 브랜드 아래의 다양한 시리즈제품을 효율적이고 직관적으로 사용할 수 있도록도와주어 소비자의 제품 사용성을 높일 수 있도록 도움을 주는 일관성이다. 이와 달리 외부적, 미학적 일관성은 외형적인통일성을 통한 가족형태(family look)를 완성하여 충성도 높은 소비자 그룹을 만드는 일관성이다. 이러한 일관성 법칙들은‘디자인 언어 시스템’이라는 디자인 과정을 통하여 제품 디자인에 반영되어 사용자가 제품을 사용할 때에 필요한 편의성 향상은 물론 향후 개발 되어질 미래의 시리즈 제품 개발에도 적용 되어질 디자인 요소들로 정리된다. 이번 연구는2012 년도부터 2014 년도 까지 순차적으로 진행하였던 일관성 법칙에 입각한 산업 및 의료용 시리즈 제품 디자인을 개발하는 과정에 관한 사례연구이다. 시리즈로 개발되었던 두 제품들은 하나의 모기업에서 기획, 개발되어 생산이 진행된산업용 장비이다. 이 제품들은 유사한 공학기술이 적용되었다는 공통점이 있었던 반면 사용 환경, 사용자, 사용방식이 전혀 다른 장비라는 차이점이 있다. 이러한 공통점과 차이점이 분명한 제품들을 하나의 브랜드 이미지로 표현 시켜야 하였고 동시에 통일된 직관적인 사용성을 소비자에게 제공함으로써 충성도 높은 소비자 그룹을 만들어야 했고 이것이 시리즈제품 개발 과정에서 요구되었던 핵심과제였다. 이러한 목적을 달성하기 위해서‘일관성 원칙’이라는 디자인 방법론 적용이 필요하였고 일관성 법칙이 적용된 ‘디자인 언어 시스템’이라는 디자인 툴을 만들어 두 개의 제품 개발에 사용하였고 향후 개발되어질 일관성 법칙이 구현된 시리즈 제품에도 적용될 것을 기대한다.

Purpose: Trochanteric fixation nail advanced (TFNA) was modified to compensate for the shortcomings of proximal femoral nail antirotation-II (PFNA-II). The clinical and radiological outcomes of surgeries using the PFNA-II and TFNA for femoral intertrochanteric fractures were compared. Materials and Methods: Eighty-two patients who underwent surgeries using PFNA-II or TFNA were analyzed. Only those who were followed up for more than a year were enrolled. Bone union, shortening of the femoral neck, and the tip–apex distance of the intramedullary nail were compared in the radiological findings. Clinical outcomes, including the frequency of complications and gait ability (Koval score), were also assessed. Results: The mean follow-up periods were 22 and 19 months for the PFNA-II and TFNA groups, respectively. In the PFNA-II group, two cases of femoral head cut-out and one case of varus collapse were observed. In the TFNA group, only one case of femoral head cut-out was observed; however, there was no significant difference in the frequency of complications between the two groups (p=0.37). Additionally, both the shortening of the femoral neck and the decrease in gait ability after surgery showed relative improvement in the TFNA group compared to the PFNA-II group; however, there was no significant difference between the two groups. Conclusion: The use of both TFNA and PFNA-II was associated with satisfactory outcomes. In patients who underwent surgeries using TFNA, the recovery of gait ability, frequency of complications, and shortening of the femoral neck were not significantly different from PFNA-II, suggesting that both are suitable instrument choices for intertrochanteric fracture treatment. However, the clinical significance must be further assessed using a larger group of patients over a longer follow-up period in future studies.

Purpose: We evaluated the differences between the clinical characteristics, procedure and results of real life cardiopulmonary resuscitation versus how CPR is portrayed in Korean medical dramas. Methods: We watched 58 episodes of Korean television medical dramas including <Surgeon, Bong Dalhee>, <New heart> and <General hospital>, broadcast during the period 2007 to 2010. We identified all occurrences of CPR in each episode and collected the fictional patients’ age, sex, location,presumed cause of cardiac arrest, and return of spontaneous circulation rate for the CPR performed, and then compared these with actual, published resuscitation statistics. Whether or not the procedure employed in a fictional CPR scene adhered to current CPR guidelines was also evaluated. Results: There were 39 occurrences of CPR in the 58 television episodes viewed, with the most common cause being cardiac arrest. The fictional ROSC rate after CPR (71.8%) differed significantly from published real life figures (p=0.072). The resuscitation process did not appear to follow current guidelines in 64.1% of the cases. Contrary to reality, the average age of patients was 41.3 years. Conclusion: The CPR provided to fictional patients in medical dramas televised in Korea is generally different than what would be provided to a patient in reality. In addition,the ROSC rate appears higher on television than what can be expected in the real world.
