최근 워크스테이션이나 오피스 설계에서 인간공학의 중요성이 대두되고 있으며 작업대 높이, 다리 여유공간, 시트 조절범위 등에 대한 인간공학 지침서가 있다. 그러나 이런 지침서가 일부 제 품의 디자인에는 적합하더라도, 많은 제품에서는 설계가 복잡하여 마네킨의 사용이 요구된다. 특히 초기 디자인의 개념과 설계의 개략적인 평가를 위해서는 마네킨의 사용이 필수적이며 특히 작업공간이 제한되거나 특수한 작업이 요구될 때는 더욱 사용성이 증대된다. 본 연구에서는 다양한 신체크기를 대표할 수 있는 마네킨을 구성하는 방법과 cad 마네킨을 모델링하였다. 우선 마네킨의 기본 구조와 형상을 결정하는데 필요한 25개 기본인체부위를 선정하고 인자분석을 통하여 이들부위의 크기를 대표할 수 있는 마네킨 그룹을 결정하였다. 또 각 마네킨 그룹별로 25개 기본 인체부위의 마네킨 설계치수를 도출하였으며 이들 값을 바탕으로 2차원 인체모형을 ANSYS로 모델링하였다.

The purpose of this study is to compare the effects on nursing students' knowledge, performance confidence, and skills from combined virtual IV simulator and mannequin arm IV cannulation training against training with a mannequin arm only. A non-equivalent control group pretest-posttest experimental study was carried out. Ninety-three sophomore nursing students who were just beginning their fundamental skills training were recruited. Participants were divided into two groups (46 for the combined group and 47 for the mannequin-only group). Data were collected from March 18-29. For the experimental group, both virtual IV simulator and mannequin-arm training were provided for 30 minutes (15 minutes each). For the control group, training for 30 minutes with a mannequin arm only was provided. After intervention, there was no statistically significant difference in the knowledge score between the two groups (F=2.52, p=.116). However, there was a significant improvement in performance confidence (t=2.14, p=.035) and nursing skills (t=5.34, p<.001) in the experimental group, compared with the control. Overall, this study provides empirical evidence that the combination of virtual IV simulator and mannequin arm training may further enhance nursing students' performance confidence and nursing skills.

In this paper, we developed a virtual cloth try-on (VTON) technology that segement the cloth image worn on the mannequin and applies it to the user 's photograph. The two-dimensional image-based virtual wear study which does not require three-dimensional information of cloth and model is of practical value, but the research result shows that there are limitations of of the current technology for the problem of occlusion or distortion. In this study, we proposed an algorithm to apply the results obtained from the DNN- based segmentation and posture estimation to the user 's photograph, assuming that the mannequin cloth reduces the difficulties in this part. In order to improve the performance compared with the existing one, we used the validity check of the pre-attitude information, the improvement of the deformation using the outline, and the improvement of the divided area. As a result, a significantly improved result image of more than 50% was obtained.

Three-dimensional (3-D) laser scans can provide a 3-D image of the face and it is efficient in examining specific structures of the craniofacial soft tissues. Due to the increasing concerns with the soft tissues and expansion of the treatment range, a need for 3-D soft tissue analysis has become urgent. Therefore, the purpose of this study was to evaluate the scanning error of the Vivid 900 (Minolta, Tokyo, Japan) 3-D laser scanner and Rapidform program (Inus Technology Inc., Seoul, Korea) and to evaluate the mean error and the magnification percentage of the image obtained from 3-D laser scans. In addition, soft tissue landmarks that are easy to designate and reproduce in 3-D images of normal, Class II and Class III malocclusion patients were obtained. The conclusions are as follows; scanning errors of the Vivid 900 3-D laser scanner using a manikin were 0.16 mm in the X axis, 0.15 mm in the Y axis, and 0.15 mm in the Z axis. In the comparison of actual measurements from the manikin and the 3-D image obtained from the Rapidform program, the mean error was 0.37 mm and the magnification was 0.66%. Except for the right soft tissue gonion from the 3-D image, errors of all soft tissue landmarks were within 2.0 mm. Glabella, soft tissue nasion, endocanthion, exocanthion, pronasale, subnasale, nasal alare, upper lip point, cheilion, lower lip point, soft tissue B point, soft tissue pogonion, soft tissue menton and preaurale had especially small errors. Therefore, the Rapidform program can be considered a clinically efficient tool to produce and measure 3-D images. The soft tissue landmarks proposed above are mostly anatomically important points which are also easily reproducible. These landmarks can be beneficial in 3-D diagnosis and analysis.

The purpose of this study was to examine the correlation between the combination of women's clothing by season and thermal insulation using a thermal manikin. A total of 34 kinds of clothing ensembles were selected based on previous studies(8 types for spring/fall, 7 types for summer, and 19 types for winter). The results were as follows: The thermal insulation of clothing ensembles($I_{cle-total}$) ranged from $0.34{\sim}0.60clo$ for spring/fall, $0.16{\sim}0.37clo$ for summer, and $0.89{\sim}1.35clo$ for winter. The correlation coefficient between the thermal insulation of clothing ensembles and thermal insulation accumulated by the individual garments composing of the clothing ensembles($I_{cle-summed}$) was 0.982(p<0.001). The correlation coefficient between the thermal insulation of clothing ensembles and total clothing layers for the upper body part was 0.750 (p<0.001), for the total clothing weight was 0.978(p<0.001), and for the covering area was 0.776(p<0.001). In conclusion, $I_{cle-total}$ showed higher relationships to the $I_{cle-summed}$ and total clothing weight than to the total clothing layers or surface area covered by clothing.

The purpose of this study was to examine the relationship between the weight of seasonal garments worn by Korean women in their daily lives and thermal insulation. We selected a total of 121 garments(13 kinds of Under garments, 51 Upper garments, 32 Lower garments, 15 Headgear, 10 Gloves Footgear) based on our previous survey using questionnaire and interview. Thermal insulation of single garment was measured with a thermal manikin. Also we measured garment weight, covering area, thickness, air permeability on the each garment(chamber air temperature: $21.5{\pm}0.5^{\circ}C$, humidity: $50{\pm}5%R.H.$ air speed: 0.15m/s). The results are as follow: The very strong positive correlation(r=0.905, p<.01) was recognized between the weight of single garment and thermal insulation. The regression equation of thermal insulation can be represented as follows: Thermal Insulation(clo)=$0.03+0.0004{\times}Garment$ Weight(g)($r^2$=0.820, SEE =0.059). There are significant differences in the thermal insulation and garment weight by season and garment type(p<.05). The each garment category's thermal insulation and garment weight has as follows: Under garment(0.06clo, 89g), Blouse Shirt T-shirt(0.13clo, 200g), Cardigan Sweater Vest(0.14clo, 287g), Coat Jacket Jumper(0.41clo, 890g), Skirt(0.16clo, 276g), Trousers(0.20clo, 438g), Headgear(0.03clo, 102g), Gloves Footgear(0.03clo, 33g).

The primary objective of this research was to suggest the design dimensions of automotive seating package that has an important effect upon seating package design. To conduct the research, a set of manikin dimensions that are representative for Korean was determined by using a statistical scheme. With these dimensions, we generated nine manikins for male and female, respectively. Also, the preferred driving posture was investigated using the experimental setup. To find each joint angle for subjects, a driving monitoring system was developed and a three dimensional motion analysis system was employed. The joint angle for the subject was established and compared with related literature. With the generated manikins and each joint angle, the driving posture was simulated by using SAFEWORK that is a program to generate manikins. The positions and adjustable ranges from the accelerator heel point to the hip point and the steering wheel center point that are important variables in order to design seating package were suggested. Further research is needed to determine the seating package dimensions three dimensionally.

Simulators were introduced in education as a tool to make advanced training standardized, less expensive, and without danger to those involved. In 1922 in the Unites States, Edward Link presented his homemade flight simulator, which became common place in both military and civilian aviation, known as the "Link Trainer". The development of mannequin simulators used for education, training, and research is reviewed, tracing the motivations, evolution to commercial availability, and efforts toward assessment of efficacy of those for teaching cardiopulmonary resuscitation, cardiology skills, anaesthesia clinical skills, and crisis management. This will provide a brief overview of simulators and trainers in several domains.
