  • through Sid View Silhouette The purpose of this study was to pro-vide basic information for elderly women's clothing construction and to develop dress forms that can reflect the charac-teristics of their bodies. The subjects were 251 elderly women aged from 60 to 81. Data were collected from 34 photographic measurements of each subject and analyzed by factor analysis cluster analysis analysis of variance. The results were as follows: 1. A decrease in height the bustline drops as age increase. From a lateral view point most of the subjects have straight posture with protruding ab-domens but the somatotype gradually bends bends forward with age. 2) Five factors were extracted from photometric measurement which explain 81.0% of variance. 3 Through cluster analysis using 5 fac-tor scores four types were categorized. Type I was turning over somatotype Type II was swayback somatotype Type III was straight somatotype Type IV was bending somatotype according to its po-sition to the relative plumb liner and their side view contour.

  • The purpose of this study is to classify the body types based on the side view. The subjects are 404 Korean and Mongolian women within the 18 to 24 age group. From the results of comparing 28 items of indirect photometric measurements, 15 items were shown to have significant differences. Mongolian women were larger in values for 13 items than were Korean women except two items, which are back projecting point height and abdominal projecting point height. The silhouette of Korean women's front body looks completely different from Mongolian women's. Especially, Mongolian women's fore-breast part is much thicker than that of Korean women. The result of analysing the indirect photometric measurement of 4 types which were previously classified by the direct measurements and index values is as follows; Type 1 is normal type, type 2 is lordosis type, type 3 is swayback type, and finally type 4 is flatback type. The groups of each of the 4 types are further divided into Korean and Mongolian women. Judging from their body types based on the side view, it seems clear that significant differences exist between Korean and Mongolian women's side body shapes in the thickness of their breast part.

  • This paper concerns the receding of the eastern coastline of Korean peninsula at a macroscopic point of view, the result is as following. 1. Eastern coast is gradually developed from maturity stage to full maturity stage. 2. The coastline recession due to sea level rise is amounted to the receding distance, x=0.045 m per yr. 3. The author proposes another classification from the new view point, which is classified by comparing quantities between river supplying sediment loads, and the littoral drifting due to wave actions. According this, eastern coast is receding(Type Q-A), and we could find it's geomorphological characteristics. 4. The general piofile of eastern coast sand beach is erosional storm profile(Type I) which accompany offshore bar. 5. From the wave measuring data of eastern coast(Hoopo port), I can derive the linear regression line of the exceedance probability of wave height from the log-normal distribution. $z=O. 113+4.335 log_lo H, r=0.983.$ Above equation made it possible to estimate $\omega[=P(H>H_c)]for the effective wave height H_c=2. Om4, 4. Om and their corresponding values are considerable (7.8%, 0.3%) 6. Eastern coastline certainly have the tendency of erosive and receding, owing to the sea level rise, poor sediment source and effective wave actions. It's very desirable to survey coastline evolution for a long time systematically, in order to make more elaborate diagnosis.

  • The foot type is classified into normal, high or low arch according to either foot print or medial longitudinal arch (MLA) height. Plantar fasciitis, heel pain, Achilles tendinitis, stress fracture, metatarsalgia, knee pain, shin splint pain, and etc are common foot disorders and associate to the foot type. The purpose of this study was to evaluate several suggested bony inclination used to classified the abnormal foot and if the arch index (AI) was correlated with foot morphology. Lateral view and dorso-plantar view of radiographic images and flatbed scanner measurements obtained from 57 college students were analyzed. Results showed that AI measured in this study was higher than Caucasian Americans and European, but similar with African. The ethnic origin could influent the AI distribution. The AI provided a simple quantitative means of assessing the structure of lateral and medial longitudinal arches. The correlation coefficients of true bone height with AI could be further improved by normalized foot width rather than foot length. AI also demonstrated as a good indicator of inclination between calcaneus-fifth metatarsal (CalM5) and calcaneus-first metatarsal (CalX), it is a good means to classify the foot type.

  • This is an attempt to evaluate normal spleen size in the Koreans. Spleen scans were obtained in 29 patients who were admitted to the Seoul National University Hospital because of trivial illnesses. All scans were performed by use of $^{51}Cr$-labelled, heat-treated erythrocyte. As a simple screening criteria for the presence of splenomegaly, vertical height of the spleen was considered to be the best one. After statistical analysis it was concluded that the upper limit of normal spleen height is 13cm in anterior view and 14cm in lateral view.

  • In recent years, there has been increased interest in characterizing and extracting 3D information from 2D images for human tracking and identification. In this paper, we propose a single view-based framework for robust estimation of height and position. In the proposed method, 2D features of target object is back-projected into the 3D scene space where its coordinate system is given by a rectangular marker. Then the position and the height are estimated in the 3D space. In addition, geometric error caused by inaccurate projective mapping is corrected by using geometric constraints provided by the marker. The accuracy and the robustness of our technique are verified on the experimental results of several real video sequences from outdoor environments.

  • 강릉의 경포는 현존하는 12개의 누정(樓亭)이 있을 만큼 예로부터 빼어난 경치를 가진 곳이다. 2007년부터 자연공원법이 일부 개정되면서 경포의 경관을 유지하던 고도규제 정책에 변화가 발생하였다. 이에 본 연구는 경포 경관의 특성을 파악하고 변화와 심리적인 영향을 검토함으로써 고도규제제도의 검토와 보완에 대한 자료를 제시하는 것을 목적으로 하였다. 연구결과는 다음과 같다. 경포호 주변에 입지한 누정에서의 가시권을 분석하여 경관관리를 위한 전략적 조망점으로 경포대와 방해정이 선정되었다. 2개의 조망점은 경포호의 주요 조망대상을 대부분 조망할 수 있는 지점이다. 27쌍의 경관형용사를 이용한 선호도 분석결과 '죽도(竹島)'로의 조망이 이루어지는 경포대 조망점에서의 경관이미지가 다소 높게 나타났다. 이는 '죽도'와 주변의 경관관리가 중요함을 보여준다. 경관심리 요인화 결과 '매력성', '쾌적성', '정연성' 등 3개의 요인이 추출되었다. 3개 심리요인이 경관선호도에 미치는 영향을 검토한 결과 '매력성', '쾌적성', '정연성' 등의 순으로 영향력을 보였다. 이러한 결과는 경포호가 파노라믹한 경관을 형성하고 있어 랜드마크를 도입하거나 개성있는 건물 경관관리가 필요함을 보여준다. 또한 자연경관과 조화를 이루는 스카이라인을 형성하여 '쾌적성'을 높이되, 일괄적 규제에 의한 관리보다 조망을 고려한 조화로운 건물군의 경관관리가 필요함을 보여준다. 건물높이에 대한 심리요인 분석결과, 조망점에 상관없이 건물의 높이가 30m 미만인 경우와 30m 이상인 경우로 선호도의 차이가 발생하였다. 이러한 결과는 경포호와 죽도, 방풍림 등으로 형성되는 자연경관의 훼손이 고도규제가 30m로 형성될 때 경관선호도에 영향을 미칠 수 있음을 보여주는 것이다. 본 연구는 경포호의 2개 전략적 조망점을 찾아내고 심리요인을 고려한 적정 고도를 찾아냄으로써 경관관리에 필요한 자료를 제시하였다. 그러나 고정된 시점과 일률적 층수변화 등의 변수는 보완되어야 할 것이다. 추후에는 건물 층수와 함께 용도, 건물 배치 등에 대한 다양한 개발 시나리오를 예측하여 정밀한 연구가 보완되어 효율적인 경포호의 경관관리 방안이 도출되어야 할 것이다.
