목적: 남녀 대학생의 동공크기, 손의 반응력, 굴절이상, 교정시력, 우위안, 정지시각(static visual angle, SVA), 동적시력(kinetic visual acuity, KVA)등을 비교 분석하고, 굴절이상이 완전교정 된 상태에서 남녀 대학생의 KVA를 측정하고, 완전교정상태에 구면굴절력 ${\pm}0.50 $D를 각각 변화시켜 KVA을 측정하여 변화를 알아보고자 하였다. 방법: 안경광학과 남학생 40명, 여학생 40명을 대상으로 KVA 측정장치(KOWA AS-4A)와 손의 반응력 측정 프로그램, 자 타각적 굴절검사기기 등을 이용하여 KVA, SVA, 동공크기, 손의 반응력, 굴절이상, 교정시력, 우위안 등을 측정하였고, 양안 구면굴절력을 ${\pm}0.50$ D 변화시켜 KVA를 측정하였다. 결과: 전체 대상자의 양안 KVA는 $0.45{\pm}0.22$이고, 단안은 우안 $0.36{\pm}0.19$, 좌안 $0.34{\pm}$0.19로 양안이 단안보다 유의하게 높게 나타났다. SVA가 좋을수록 KVA가 유의하게 좋은 것으로 나타났으며, 굴절이상은 근시량이 작을수록 KVA가 좋았으나 통계적으로 유의하지 않았다. 난시에서는 -1.00 D 이하와 초과로 나눌 때 난시가 작을수록 KVA가 유의하게 좋았다. 굴절이상 교정상태에 따른 KVA는 완전교정일 때 $0.45{\pm}0.22$, 완전교정에 +0.50 D 추가할 때 $0.26{\pm}0.15$, 완전교정에 -0.50 D 추가할 때 $0.48{\pm}0.22$로 근시 교정을 강하게 할 때가 유의수준에서 KVA가 가장 높게 나타났으며, 다음으로 완전교정, 근시 저교정의 순으로 낮게 나타났다. 또한 남녀로 구별하여 비교해 볼 때도 유사한 결과를 나타냈으며 남자가 여자보다 KVA가 좋은 것으로 나타났다. KVA와 우위안 비우위안 차이는 없었다. 결론: 따라서, KVA는 원거리 SVA, 난시량, 굴절이상량과 관계가 있는 것을 알 수 있었으며, 우위안과는 관계가 없었다. KVA를 높이는 굴절이상 처방은 완전교정 또는 근시방향에서 약간 과교정 하는 것이 효과적인 것을 알 수 있었다.

Background: Both the rapid concentric and eccentric contractions during exercise repeatedly impose excessive stress on muscle tissue. The hamstring muscles are very susceptible to injury due to the tensile stress. Various interventions are currently being undertaken to prevent strain injury before exercise. Stretching is the most common method and is known to have a positive effect on flexibility and muscle performance. However, relatively few studies have investigated the potential negative factors of stretching. Objects: The purpose of this study was to examine changes in pain following the different intensity of the stretching and types of physical stress. Methods: The subjects were divided into three groups based on the intensity of stretching: 100% (S100), 75% (S75), and 50% (S50) of the measured force at the point of discomfort in static stretching and 100% (P100), 75% (P75), and 50% (P50) of the maximum voluntary isometric contraction in Proprioceptive Neuromuscular Facilitation (PNF) stretching. The pain individual subjects perceived after stretching was measured via a Visual Analog Scale (VAS) and compared between the groups Results: Despite the decrease in the intensity of static stretching, no decrease in VAS value was observed. In PNF stretching, a significant decrease was observed at P50 compared to P100. S100 was significantly higher than P75 and P50. Conclusion: Previous studies have shown that PNF has a superior or the same effect on flexibility in comparison with static stretching. This effect was maintained even in moderate intensity. PNF stretching performed under moderate rather than high intensive static stretching, which causes pain and discomfort, might be recommended in clinical settings.

Background: The purpose of this study was to effect of prenatal exercise program combined with Brugger's exercise on low back pain and balance in pregnant women. Design: A Single-Subject Study. Methods: This study was applied to 28 weeks of pregnant women who complained of low back pain for a total of 4 weeks. A total of 10 prenatal exercise programs in this study consists of sessions, and each session was applied with a Bruger exercise for 1 minute before the start. For the fatigue and safety of pregnant women, a break for 1 minute was provided for each session and was conducted under the supervision of the therapist The visual analogue scale (VAS), Oswestry disability index (ODI), and static balance (BT-4) were measured to evaluate the pregnant women's low back pain and balance ability before and after the intervention Results: The change in back pain after the intervention was VAS 5 before the intervention, but the VAS gradually decreased at 4 weeks after the intervention. Reduced to VAS 2 after 4 weeks of intervention. The Oswestry Disability Index (ODI) was 54%, which was at the level of severe disability, but the dysfunction index gradually decreased 4 weeks after intervention, reaching 19% in 4 weeks, and there were no problems with daily life. As for the static balance ability, the sway area and the sway distance values gradually decreased after the intervention in both the eyes open and closed state, showing an improvement in the static balance ability of pregnant women after the intervention than before the intervention. Conclusion: The prenatal exercise program combined with Brugger's exercise was effective to improve low back pain and static balance in pregnant women. The result of this study may helpful as basic data for obstetric physical therapy.

Due to climate change and aging of reservoirs, damage to embankment slopes is increasing. However, the safety diagnosis of the reservoir slope is mainly conducted by visual observation, and the time and economic cost are formidable to apply soil mechanical tests and slope stability analysis. Accordingly, this study presented a predicting method for the compaction and strength characteristics of the reservoir embankment soil using a portable static cone penetration test. The predicted items consisted of dry density, cohesion, and internal friction angle, which are the main factors of slope stability analysis. Portable static cone penetration tests were performed at 19 reservoir sites, and prediction equations were constructed from the correlation between penetration resistance data and test results of soil samples. The predicted dry density and strength parameters showed a correlation with test results between R² 0.40 and 0.93, and it was found to replace the test results well when used as input data for slope stability analysis (R² 0.8134 or more, RMSE 0.0320 or less). In addition, the prediction equations for the minimum safety factor of the slope were presented using the penetration resistance and gradient. As a result of comparing the predicted safety factor with the analysis results, R² 0.5125, RMSE 0.0382 in coarse-grained soil, R² 0.4182 and RMSE 0.0628 in fine-grained soil. The results of this study can be used as a way to improve the existing slope safety diagnosis method, and are expected to be used to predict the characteristics of various soils and inspect slopes.

The purpose of this study was to identify the differences of the static and the dynamic balance reactions in the flexion syndrome (FS) and the extension syndrome (ES) group of the patients with chronic lowback pain (LBP) and healthy subjects. Twenty subjects were included in each group. By using EquiTest 5.02, the static balance was measured by the equilibrium score and the strategy score of sensory organization test (SOT), while the dynamic balance was measured by the latency of motor control test (MCT) and the sway energy of adaptation test (ADT). Oswestry Disability Index (OSI) was used to measure level of the disability in patients with chronic LBP. The equilibrium scores, the strategies of SOT, and thelatencies of MCT of three groups were compared with one way ANOVA, while the sway energy of ADT was compared with repeated measures one way ANOVA. The results of this study showed that the equilibrium scores and the strategy scores of SOT were significantly lower in patients with chronic LBP than in healthy subjects. The equilibrium scores and the strategy scores of SOT were significantly differences between the FS and ES groups in condition 5 (support surface was sway-referenced and visual information waseliminated by eye closure), and 6 (support surface was sway-referenced and visual information was altered by sway-referencing). The FS group showed delayed average reaction time at large posterior translation, however, the ES group showed delayed average reaction time at large anterior translation, Even though the sway energy of the patients with chronic LBP were greater than that of healthy subjects during the toe down (plantar flexion rotation), the values between the FS and ES groups didn't show any significant difference. The disability level showed highly correlation with the equilibrium score of the condition 5. As the results, the FS and ES groups divided by the their symptoms and signs in patients with chronic LBP showed different balance reaction. Therefore, more accurate evaluation and balance treatments are needed to focus on their symptoms and signs in patients with chronic LBP.

픽처레스크 미학과 풍경화식 정원은 자연을 그림과 같이 정태적으로 감상하게 만드는 이른바 회화적 자연관의 전범으로 인식되어 왔다. 이러한 해석은 당시의 시각 문화를 선원근법에 의존하여 설명한 데에서 연유한다. 실상 당시는 새로운 시각 매체의 발명에 따라 종래의 원근법에 기반했던 시각성이 '유동적인 시각'과 '시점의 상대성'으로 요약되는 '움직이는 시각성'으로 변모해가는 바로 직전의 시기였다. 이 연구는 그러한 시각 문화의 변동에 주목하여 픽처레스크 미학과 험프리렙턴의 시각 매체에서 나타나는 '움직이는 시각성'의 징후를 읽어내고자 한다. 18세기 독일의 정원 이론가 히르시펠트는 풍경화식 정원은 구불구불한 선을 이용하여 움직임의 환영을 만들어낼 수 있으므로 다른 예술 형식보다 우월하다고 분석했다. 18세기 말 야기된 픽처레스크 논쟁에서 아마추어 이론가들은 회화에서 복잡하고 다채로운 시각의 변주를 중요하게 여기고, 정원도 그러한 시각적 자극이 만들어지도록 설계해야 한다고 주장했다. 렙턴의 "레드북"에 수록된 스케치에서는 움직이는 시각성이 반영된 다양한 재현 전략들이 발견된다. 렙턴은 속도의 차이를 고려하여 여러 유형의 길을 체계적으로 설계했고, 인간의 시각장을 표현하기 위해 회화적 프레임이 아닌 파노라믹 뷰를 활용하였으며, 현실에서의 움직임과 유사한 시각적 경험을 만들어내기 위해 여러 스케치들을 전략적으로 배열하였다. 이와 같이 픽처레스크 미학과 렙턴의 시각 매체는 당대 시각 문화에 새롭게 등장하기 시작한 움직이는 시각성을 반영하고 있었다.

The purpose of this study was to discover the landscape visual image of the slope scene and their harmony with surrounding sceneries. This research utilized the basic study tool of psycho-physics and processed the case study of ten types of slope construction scene along the highway. The analysis was performed by the data obtained from the questionnaires and the photos for the slope construction scene. The questionnaires for analysis the image of the slope construction scene and their harmony with surrounding sceneries were designed using semantic differential scale and 5 point Likert-scale. The major findings were as follows. 1. At the part of the visual preferences analysis, the slope revegetation methods showed high level of preferences generally than on the slope structure methods. While the slope revegetation methods were estimated friendly, continuity, harmonious, soft, light and wide, the slope revegetation methods were estimated unstable, female, static, simple, omnipresent, appeared as policeman of weak inclination. Also the slope structure methods were estimated stable, manly, complicated, steep and healthy but rough, unharmonious, unfamiliar and heavy. 2. Psychological factors, related to the satisfaction for the slope revegetation methods were composed of three factors, aesthetic, individuality and physical character. And the slope structure methods were composed of five factors, aesthetic, individuality, stability, physical character, and complexity. 3. At the part of harmony with surrounding landscapes, the slope revegetation methods were evaluated highly but the slope structure methods received the lowest evaluation. Also the harmony analysis with surrounding view on the slope revegetation methods showed degree of high more than average in all texture, form, color and scale but the slope structure methods showed degree of fewer than average degree in form, scale, color and texture.

Typography, as the median for communication, has expanded its roles according the attributes of the media where it Is used, and the change of media follwing the change of times is presenting new directions to the field of typography. The attempts of 20C experimental typography prioritize visual formativeness, free typography and language started to appear on printed matters and different kinds of prints put pep in magazines. Thus, experiments in the aspects of effective delivery of inpormation that letters have and aesthetic side of shapes of letter are continuing. Today with the appearance of multimedia, development of visual colture and rapid development of digital technology, the range of experimental typography has expanded even wider and therefore, different kinds of expressions became possible. As seen above, unlike the existing static printed media that carries linguistic information only, letters in the multimedia environment is shown in the movie titles, TV or web not only as a basic visual media such as type and image, but as a dynamic and complex factor that contains additional information of motion and sound factor. This study will attempt to find the historic context of focus of moment from the kinetic art and define the moving letters as kinetic typography. Therefore, this paper will have an understanding on kinetic typography's background, concept and characteristics following the change of communication environment in the multimedia era and tried to study the basic theories of kinetic typography and the information delivery and imagery function of letters. Also, this paper attempted to carry out a study on whether kinetic typography is delivering information smoothly from the aspect of communication through the image role as delivering information by studying major works of artists who have influenced kinetic typography. Based on this study, I would like to suggest new direction for effective delivery of information and value of use.
