본 연구에서는 로봇디자인에 대한 선호 반응의 결과를 바탕으로 로봇 얼굴을 구성하는 조형요소의 조합 관계에 대한 특성을 분석하는 것이 기본적인 목적이다. 아울러 분석 결과로부터 선호도를 향상시키기 위한 디자인가이드의 제시 가능성을 고찰하고자 하였다. 이를 위하여 27가지의 로봇 얼굴 사진을 실험자극으로 선정하고, 선호 반응 및 연상 반응에 관한 실험을 진행하였다. 실험 결과, 로봇 얼굴의 형태 보다는 눈의 형태가 선호 반응에 많은 영향을 미치는 등 다양한 특성이 나타났다. 이러한 결과를 바탕으로 로봇 얼굴에 대한 선호반응에 긍정적 영향을 미칠 수 있는 각 조형요소의 특성 도출 및 기본적 디자인가이드라인을 제시할 수 있었다. 구체적으로 먼저, 눈의 형태는 세로의 길이가 가로 길이 보다는 긴(167%) 타원형을 적용하는 것이 필요하다. 그리고 눈 사이의 거리는 얼굴 폭의 35% 정도를 유지해야 한다. 또한 눈의 위치는 얼굴의 중심축으로부터 상향에 배치하여 시각적으로 안정감을 주는 것이 중요하다. 머리 전체의 형태는 원형을 이용한 구 타입이 바람직하다. 머리의 형태와 눈과의 조화는 로봇으로서 기본적으로 갖추어야 할 귀엽고 깜찍한 이미지를 구현하는 것이 필요하다. The fundamental goal of this study is to analyze characteristics of combined relations of formative element factors that compose robot`s face based on a result of preference response from robot`s design. Also, in order to improve preference from the analysis result, this study intended to inquire into possibilities of suggesting design guideline. For these, pictures of 27 different kinds of robot faces were selected as experimental stimuli, and experiments of preference response and association response were performed. As a result of the experiments, various characteristics were achieved such as robot`s eye shape having greater influences than facial structure, etc. Based on the result, formative element factor characteristics that could positively influence preference response on robot`s face could be drawn and a basic design guideline could also be suggested. An eye should be oval so that the length-to-width ratio may be 1.67:1. The distance between both eyes should be 35% of the facial width. Also, eyes should be above the central latitude of the face so that they may be visually stable. It is advisable to round the face generally. Eyes should be harmonious with the face so that the robot may seem cute and charming.

In the early period (B.C) the definition of he primary varivose vein in lower extremity was dilated, toruous and elongated vein. The care of varicose vein is directed toward ablation of pathologic vessels. This is achieved by removing them surgically or by obliterating them with sclerotherapy. The sclerosing agents first used. however, were too strong to be used successfully for the treatment of such veins. The introduction of less toxic sclerosing agents now makes it possible to treat varicose vein safely, reliably, and easily. Purpose: We has been tried the clinical reserch because of good result & possibility of therapy by only sclerotherpy in well defined selected indication of primary varicose vein. Method: We reviewed primary varicose vein involved in lower extremity of 463 cases that was well treated by sclerosing agents to Dept of Surg, Kangbuk Samsung Hosp, SungKyunKwan University College of Medicine, From January 1996 To December 2000. Result: 1. The distribution of the age were the first, 4th decade (40.2%), followed by 5th decade, 3th decade. The ratio of sex were more prevalent in female than male (1:10). 2. Sx & sign were showed cosmetic problem (60.5%) in most patients, followed by pain (18.8%), swelling (9.3%), Heaviness (7.1%). 3. The duration of illness were over 5 yrs in most patient -373 cases (80.6%). 4. The associating factor were correlated with pregnancy in most female (33.7%), others were family Hx (7.8%), long standing posture, DM, HTN, Trauma. 5. The size of varicose vein were type Ⅱ in case 312 (67.4%), followed by type Ⅲ (27.4%), type Ⅰ (4.1%), type Ⅳ(1.1%) according to the classification by Dr. Weiss. 6. The frequency of injection were 2~4 injection (68.3%) in most patient. During 4months of injection therapy, almost varicose veins were disppeared (91.4%). 7. Post injection complication were thrombosis in 38 cases, followed by hyperpigmentation in 25 cases, necrosis in 8 cases. 8. Recurrence rate after injection were extremely rare (6 cases). Conclusion: The sclerotherapy of telangiectasia (type Ⅰ,Ⅱ) is highly effective. The treatment based on knowledge of venous anatomy, of sclerosing agents in highly likely to be successful.
