The purpose of this study was to investigate the effect of visual feedback on the postural control of stroke patients, by systematically varying conditions of visual feedback [eye-open condition (EO) vs. eye-closed condition (EC)], and base-support (both-side support, affected-side support, and unaffected-side support). In this study, we allocated 41 stroke patients with no damage in the cerebellum and visual cortex who can walk at least 10 meters independently, and 35 normal adults who have no experience of stroke to the control group. Both groups were asked to perform a "sit-to-stand" task three to five times, and their postural control ability was measured and compared in terms of asymmetric dependence (AD) instead of the traditional symmetric index (SI) in the literature. The results showed that although both subject groups maintained better postural control in the EO condition than in the EC condition, the patient group appeared to be more stable in EC than in EO when they were required to perform the task of the support condition given on the affected side. These results implied that visual feedback can impair stroke patients' postural control when it is combined with a specific support condition.

Purpose. The purpose of this study was to test the effects of infant massage (auditory (mother's voice), tactile/ kinesthetic (massage) and visual (eye to eye contact) stimulation) on weight and height of infant and mother-infant interaction with normal infants over a period of 4 weeks. Method. This study was designed as a nonequivalent control group pretest-posttest design. The experimental group infants (aged 2-6 months) participated in one of the infant massage programs at the health district center for 4 weeks. The control group (N=26) was paired with the experimental group (N=26) by matching the infant's age and sex. Infant weight, height, and mother-infant interaction were measured two times and recordings of the mother-infant interaction were done using the video equipment in a room at the health center for 10 minutes. Results. After 4 weeks of massage, there were no significant differences weight gain and height increase between the two groups. Comparison of the total scores for the mother-infant interaction between the two groups showed a significant difference (t=5.21, p=.000). There were also significant differences on maternal response (t=3.78, p=000), infant response (t=5.71, p=000) and dyadic response (t=4.05, p=000) in the mother-infant interaction between the two groups. Conclusion. Overall, the results of this study reassure that infant massage facilitates the mother-infant interaction for infants and mothers who give massage to their baby.

본 논문에서는 실시간 방송 및 스마트 미러 등과 같은 사용자 개인 또는 다른 사용자들과의 상호 작용이 가능한 인터렉티브 텔레프롬프터의 개념을 소개, 논의하고 실제 제작 사례를 제시한다. 이 적용 분야에서는 사용자 자신 또는 사용자와 제3자 사이의 시선의 일치가 심리적인 측면과 비음성적 커뮤니케이션에서 중요한 역할을 차지한다. 그러나 일반적인 모니터와 카메라의 조합만으로는 실제 거울을 보는 것과 같은 시선 일치를 구현하기가 쉽지 않기 때문에, 기존 방송 현장에서 널리 사용하는 텔레프롬프터의 원리를 응용한다. 제안하는 설계에서는 기존 방식과는 달리 깊이 정보를 통한 제스처 인식까지 구현하며 가시광선 정보와 적외선 정보 각각의 효율적인 처리를 위해서 텔레프롬프터에서 핵심적인 역할을 담당하는 빔 스플리터의 설계 사례와 실험 결과를 제시한다.

Whether cyclin D1 (CCND1) gene variants increase susceptibility to head and neck cancer (HNC) is undetermined. Therefore, we performed the present meta-analysis to systematically assess any possible association between CCND1 variants (G870A and G1722C) and HNC risk. Seventeen studies for CCND1 G870A and three studies for CCND1 G1722C were included. Overall, CCND1 polymorphisms (G870A and G1722C) had no association with increased HNC risk (p>0.05). In the subgroup analysis by smoking status, significantly increased HNC risk was found among smokers under allele contrast, homozygous comparison and recessive models (p<0.05), smoking carriers of A allele and AA genotype appearing at elevated risk. In conclusion, while there was overall a lack of any association between CCND1 polymorphisms (G870A and G1722C) and HNC risk, smokers carrying the A allele and AA genotype of the CCND1 G870A polymorphism may be susceptible to HNC development.

세계는 안구 질병 치료, 시력 회복 서비스, 훈련된 안과 전문의의 부족 등 안과 측면에서 어려움에 직면해 있다. 안구 병리를 조기에 발견하고 진단하면 시각 장애를 예방할 수 있다. 하지만 기존의 망막 영상 공개 데이터 세트는 임상에서 발견되는 다양한 질병으로 구성되어 있지 않기 때문에 다양한 안구 질환을 분류하는 방법을 개발하기가 어렵다. 본 연구는 2021 ISBI challenge에서 공개된 데이터 세트인 Retinal Fundus Multi-disease Image Dataset (RFMiD) 을 이용하여 안구 질환을 분류하는 방법을 제안한다. 본 연구의 목표는 망막 이미지를 정상, 비정상 범주로 선별하기 위한 강력하고 일반화 가능한 모델을 개발하는 것이다. 제안된 모델의 성능은 수신자 조작 특성 곡선 아래 면적 점수로 비공개 테스트 데이터 세트에 대해 0.9782의 값을 보여준다.

This research has the purpose to examine the images sought for, makeup Consciousness, and behavioral aspects during makeup by the college girls in their 20s in the region of Daeieon and Chungnam that have strong interest in appearance and start color makeup in full scale, who form the main consumer layers in cosmetics market, and to analyze their preference on colors and feelings by the kinds of cosmetics, and their cosmetics purchase behavior. A questionnaire survey on the college girls in Daejeon and Chungnam region has shown the following results. The biggest reason college girls do the makeup was for a refined and pure image as well as protection of skin and covering defects. Their greatest concern was skin protection, and as for color selection, harmonizations of skin color and hair color were the largest consideration. In addition, the type of makeup they do most was foundation makeup, while pink was the most frequent lipstick color, and lip glow was mostly normal colors. However, they mostly answered that they do not use eye shadow, eye runner, and foundation. It was shown that their cosmetics purchase p]aces were specialized discount stores for about 47% nearly half of them, and they consider colors the most for lipsticks and eye shadows, and affinity to skin for foundations and basic cosmetics.

The aim of this study was directed at exploring the possible use of muscle fiber characteristics as new selection traits for improving both porcine lean meat production and quality. A total of 174 (114 Yorkshire, 30 Landrace, and 30 Meishan) pigs were used for this study, and lean meat production ability was estimated by backfat thickness and loin eye area. The Longissimus dorsi muscle was taken in order to measure meat quality and muscle fiber characteristics. Due to the high correlations between total muscle fiber number and most of the performance traits, all pigs were classified into three groups (low, intermediate, or high) by total muscle fiber number using cluster analysis. The high group had the highest loin eye area (p<0.001). The meat quality traits were within normal ranges as reddish pink, firm, and nonexudative (RFN) pork, but the groups classified as intermediate and high had relatively large drip loss percentages (p<0.05), produced more than twice the amount of pale, soft, and exudative (PSE) pork as compared to the low group. The group with a high total muscle fiber number was further classified, based on type 2b fiber percentage, into low or high groups by cluster analysis. The results showed that the low type 2b fiber group had good loin eye area (p<0.05), small drip loss (p<0.05), and did not produce PSE pork. For these reasons, a high total muscle fiber number, with a low percentage of type 2b fibers, may be suitable in selecting for improvements in both lean meat production and meat quality.

Background: The purpose of this study is to investigate the effect of the combined exercise program on the static balance ability of the lumbar instability of adults. Methods: The experimental group was divided into two groups and randomly. The experimental group 1 (Exp 1) applied the combined exercise program for the lumbar stabilization exercise and strengthening exercises and the experimental group 2 (Exp 2) applied the combined exercises program for the lumbar stabilization exercises and active stretching exercises. Each experiment group performed exercise program for 4 weeks, 3 times a week, 30 minutes a day. Static balance ability was measured using GOOD BALANCE system. Results: As the comparing results of static balance ability, normal standing eye open was Ant-Post and Med-Lat showed significant differences in Exp 1 (p<.05). One leg left eye open was velocity moment showed significant differences in Exp 1 (p<.05). and one leg right eye open was Med-Lat showed significant differences in Exp 1 (p<.05). Conclusion: These results show that thoracic self mobilization is immediate effective on balance and gait ability. Thus, thoracic self mobilization will help recovery of balance and gait ability in acute stroke patients.
