  • In order to provide the basic data for creating the environment which can efficiently reflect prefer fit along with body size when selecting clothes size in the indirect purchasing environment, this study analyzed the difference of ready-made jacket part-specific fit preferred by fashion models in their twenties and female college students. This study was to analyze the impact of body size, recognition of body part-specific characteristics shape, body satisfaction on prefer fit of jacket. As for the difference of prefer fit depending on the body size, female college students preferred more loose fit than models. The difference according to recognition of body part-specific characteristics shape turned out to be significant for prefer fit depending on the degree of bend of neck, arm length, bend of back recognition and matching fit was found to be preferred as they recognize their body shape to be normal and the difference according to body satisfaction appeared to be significant in the terms of bend of back, hip width/protrusion, torso size/length, sleeve length, whole body shape and they turned out to prefer matching fit as they are satisfied with their body. As shown above, body size, recognition of body part-specific characteristics shape, especially body satisfaction have a great influence on prefer fit of jacket and therefore, if preparing for a size selection step according to body shape and satisfaction in the jacket size selection process, customers' satisfaction in jacket size may be improved and it is considered to be helpful for both consumers and sellers.

  • 본 논문에서는 얼굴 영상간의 위상 차를 이용하여 얼굴을 인식하는 시스템을 제안하였다. 제안된 시스템에서는 KLT(Karhunen-Loeve transform)를 이용하여 복구가 가능하도록 영상을 압축하고, 계산량도 줄였다. 압축된 학습 대상 영상을 미리 제안된 시스템에서 학습시킨 후, 인식 대상 얼굴 영상을 압축시킨다. 압축된 영상과 기존의 학습된 얼굴영상들과의 위상차를 구하고 이 위상차에 여현 함수를 적용하여 그 값이 최대가 되는 얼굴로 인식하도록 하였다. 두 얼굴 영상의 위상차는 벡터 내적방법에 의해 구하여지며, 이를 이용하면 기존의 학습방법을 이용하는 시스템보다 계산이 간단하고 처리시간도 빠르다. 또한 영상간 규준화된 위상차는 조명 및 회전에 불변인식이 가능하고, 여현 함수의 적용으로 이동에도 어느정도 불변인식이 가능하다. 그리고 연결웨이트에는 영상에 대한 정보를 그대로 갖고 있어서, 기존의 신경망과 같은 전체적인 재학습을 하지 않고도 새로운 영상만을 추가학습이 가능하므로 확장학습이 용이하다. 각각 10가지 얼굴영상을 갖는 40 명의 ORL 얼굴영상에 실험한 결과, 인식률이 기존의 방법과 비슷한 8% 오차범위 내에서 학습시간이 PC에서도 수 분밖에 안 걸리는 빠른 얼굴인식이 가능함을 확인하였다.

  • Smart homes are the new generation of homes where pervasive computing is employed to make the lives of the residents more convenient. Human activity recognition (HAR) is a fundamental task in these environments. Since critical decisions will be made based on HAR results, accurate recognition of human activities with low uncertainty is of crucial importance. In this paper, a novel HAR method based on a difference of convex programming (DCP) problem is represented, which manages to handle uncertainty. For this purpose, given an input sensor data stream, a primary belief in each activity is calculated for the sensor events. Since the primary beliefs are calculated based on some abstractions, they naturally bear an amount of uncertainty. To mitigate the effect of the uncertainty, a DCP problem is defined and solved to yield secondary beliefs. In this procedure, the uncertainty stemming from a sensor event is alleviated by its neighboring sensor events in the input stream. The final activity inference is based on the secondary beliefs. The proposed method is evaluated using a well-known and publicly available dataset. It is compared to four HAR schemes, which are based on temporal probabilistic graphical models, and a convex optimization-based HAR procedure, as benchmarks. The proposed method outperforms the benchmarks, having an acceptable accuracy of 82.61%, and an average F-measure of 82.3%.

  • Artificial intelligence is evolving rapidly in the ICT field, smart convergence media system and content industry through the fourth industrial revolution, and it is evolving very rapidly through Big Data. In this paper, we propose a face recognition method based on object recognition based on object recognition through artificial intelligence. In this method, Were experimented and studied through the object recognition technique of artificial intelligence. In the conventional 3D image field, general research on object recognition has been carried out variously, and researches have been conducted on the side effects of visual fatigue and dizziness through 3D image. However, in this study, we tried to solve the problem caused by the quantitative difference between object recognition and object recognition for human factor algorithm that measure visual fatigue through cognitive function, morphological analysis and object recognition. Especially, The new method of computer interaction is presented and the results are shown through experiments.

  • Objectives: The purpose of this study was to investigate recognition, dietary attitude and education needs for reducing sodium intakes of dietitian at customized home visiting health service (CHVHS). Methods: The subjects were 75 dietitian at CHVHS. We investigated several variables (recognition, dietary attitude, education needs for reducing sodium intakes) and determined sodium intakes level of subjects as 'low', 'middle' and 'high' by Dish Frequency Questionnaire 25 (DFQ 25). Also, we assessed the differences in recognition, dietary attitude, sodium intake level and education needs by dietitian career period (under 3 yrs vs. over 3 yrs) at CHVHS. Results: In recognition related reducing sodium intake, they showed 'checking a sodium content in nutrition labeling' score 2.5/4.0 and 'perception difference between sodium and salt' score 3.1/4.0. There was no difference in the recognition between under 3yrs' group and over 3yrs' group. In dietary attitude related reducing sodium intake, they showed 'palatability for salty taste' score 0.8/1.0, 'attitude in related soups' 0.7/1.0, 'attitude in related using natural spice' 0.6/1.0. There was a difference in 'attitude in related soups' between under 3yrs' group and over 3yrs' group (0.6 vs. 0.7). In sodium intake level by DFQ 25, they showed 'low group' 41.3%, 'middle group' 41.3% and 'high group' 17.3%. There was no difference in the distribution of sodium intake level by the career. In education needs related reducing sodium intakes, there were 'teaching experience' 93.3%, 'have a difficulty in teaching about reducing sodium intakes' 86.6%, and 'necessity of education for CHVHS dietitians' 100.0%. 'Needed education contents for CHVHS dietitians' were ranked as 'cooking way to reduce sodium intake' 58.7%, 'relation between hypertension and sodium' 17.3%, 'composing way to reduce sodium intake' 17.3%. There was a difference in needed education contents 'relationship between hypertension and sodium' (33.3% vs. 2.6%) and 'The cooking way to reduce sodium intake' (38.9% vs. 76.9%) by the career. Conclusions: The results suggested that a capacity training program for reducing sodium intake may be needed for dietitians at CHVHS to improve health of the community elderly. For effective training program related reducing sodium intake for dietitians at CHVHS, it may be necessary to consider the career period as dietitians at CHVHS.

  • The purpose of this study is to provide the necessary data for the effective performance of school nurse's work by comparing with the recognition and expectation on school nurse's work by the students and their teachers in school settings. The sample of this study was consisted of the 441 students and 535 teachers in Suwon. The data were collected by means of a structured questionnaire from 24th, Sept, to 29th, Sept. 1990. The collected data were analyzed utilizing SAS/PC program for percentage, frequency, mean, standard deviation and chisquare test. The major findings of this study were as follows: 1. The result of analysis in recognition on school nurse's work. There is no statistically significant difference 'depending on teachers' school level, sex, age and career with school nurse(P>0.05). The students show significant difference on their school level and sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest recognition and school environment management has the lowest recognition. 2. The result of analysis in expectation on school nurse's work. There is statistically significant difference depending on teachers' and students' school level: the order of expectation is elementary, middle, and high school(P<0.05). In the result of comparison with students' and teachers' expectation in the same school level, there is significant difference only in elementary school(P<0.05). However, there is no statistically significant difference depending on teachers' sex, age, career with school nurse and students' sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest expectation and school environment management has the lowest expectation. Synthesizing the result of the study, we can have the conclusion like following. First, students' recognition on school nurse's work is lower than teachers' because most of school nurse's work is performed through their homeroom teachers or other teachers. That can be the limitation for students to recognize school nurse's work. So, there must be a chance of regular meeting between school nurse and students to perform school nurse's work effectively. For this. we must change our educational system and make school nurse charge regular lesson. Second, in each area of school nurse's work, both students' and teachers' recognition and expectation about the area of school environment management has much lower score than the other areas. This indirectly shows the school nurse don't do the work of the area actively. So, school nurses must make an effort to do the work of the area actively. And we must enforce the education of this area in education for new school nurses or re-education for school nurses.

  • 삶의 질 측정은 행정, 경제, 사회 분야에서 연구를 진행해 온 개념이며, 정부의 업무 성과를 측정하는 기준이 되기도 한다. 따라서 최근에는 국가적으로나 국제적으로 전반적인 발전 정도를 반영하기 위해 '삶의 질(QoL: Quality of Life) 지표'를 사용하는 추세이다. 삶의 질 지표를 활용한 국가 정책 및 서비스의 효과 측정은 '상향확산이론(bottom-up spillover theory)'과 결합하여 더욱 설득력을 가지게 된다. 본 연구는 통계청에서 사용하는 객관적인 삶의 질 측정 지표인 "국민 삶의 질 지표"를 적용하여 도서관 서비스가 실제로 삶의 질 범주에 영향력이 있다고 인식하는지에 대한 정도를 조사하고, 나아가 사서가 인식하는 삶의 질 향상 정도와 일반 이용자가 인식하는 삶의 질 향상 정도의 차이가 있는지 알아보았다. 그 결과 '시간 부족에 대한 인식'이 가장 높은 지표로 나타났고, '미세먼지 농도'가 가장 낮은 지표로 나타났다. 사서와 이용자 간의 인식 차이는 13개 지표에서 유의미한 차이를 나타냈으며, 성별에 따른 인식 차이는 5개 지표, 연령에 따른 인식 차이는 23개, 거주지에 따른 차이는 14개, 도서관 방문 횟수에 따른 차이는 9개 지표로 나타났다.

  • Objectives : The oral health education for interaction between snack and oral health is made more in detail, it seems to contribute to improvement of oral health by reducing occurrence of dental caries. Methods : This study performed the survey for 530 high school and college students living in Y City, Chungbuk for 10 days from June 14, 2011 to understand the difference by the level of snack recognition. 530 copies of questionnaire were collected, the final 502 copies were analyzed and the results are as followings. Results : 1. As for the snack intake frequency, 'sometimes' and '2~3 times a day' was found to be largest with 32.0% respectively in female and 'sometimes' was largest with 34.9% in male. As for the '2~3 times a day' was most in high school students with 31.5% and 'sometimes' was most in college students with 39.0%. 2. As for snack characteristics, 'crispy' was most preferred in female and male with 43.7% and 39.4% respectively and, by school year, high school students and college students preferred 'crispy' most with 39.1% and 46.0% respectively. 3. As for the item of meal, 'sometimes skip' was most in female with 46.1% and 'all three meals a day' was most im male with 51.4%. 'All three meals a day' was proved to be most with 48.3%in high school students and 'sometime skip' was most in college students with 48.0%. 4. As for the difference of oral health management by school year, college students ($3.37{\pm}0.70$) proved to be higher in the oral health management (p<.01) than high school students ($2.98{\pm}0.81$) and the Negative snack recognition group ($3.24{\pm}0.73$) was found to be higher in the oral health management (p<.01) than the Positive snack recognition group ($3.06{\pm}0.82$). Although the interaction between school year and snack recognition level was not different in case of college students, the Negative snack recognition($3.17{\pm}0.77$) proved to manage higher oral health (p<.05) than the high snack recognition gathering ($2.81{\pm}0.80$) in case of high school students. 5. As for the difference of the oral health most im male wex and). Although the innteractifemale ($3.39{\pm}0.72$) proved to most the oral health (2.(p<.01) than male ($2.81{\pm}0.75$) and the group with Negative snack recognition terac ($3.24{\pm}0.73$) most d the oral health (2.(p<.01) than the group with Positive snack recognition level ($3.06{\pm}0.82$). As for effects of interaction between sex and snack recognition level, while there was not much difference in the oral health management by the snack recognition level in case of female, the cluster of low snack recognition level ($3.03{\pm}0.69$) proved to manage the oral health more (p<.01) than the gathering of high snack recognition level ($2.59{\pm}0.75$). Conclusions : To see the results as above, it can be seen the oral health management is higher as the snack recognition level is higher by sex and school year.

  • 이전의 연구들이 외부 피드백 정보에 대한 반응민감도에 성격특성적 개인차가 반영된다는 사실을 밝힌바 있지만, 재인기억과 관련한 의사결정에서 이러한 기질 혹은 특성적 개인차가 어떻게 관여하는지는 아직 알려진 바가 없다. 본 연구는 재인기억 과제에서 피드백에 근거한 의사결정 준거의 순응적 변화정도와 피드백에 대한 일반적 반응민감도의 개인차간 관계를 살펴보았다. 통제 조건인 실험 1에서는 올바른 피드백 조건이 의사결정 준거의 유동성에 영향을 미치지 않음을 보인 반면 피드백 조작이 이루어진 실험 2에서는 확신도가 높은 오기억 반응에만 선택적으로 편향된 피드백이 주어졌음에도 전반적인 Old/New 반응 범주의 결정준거 또한 순응적으로 이동함이 나타났다. 보다 중요하게 이 피드백에 근거한 의사결정 준거 학습에 나타나는 개별 피험자들의 반응민감도 차이가 강화 추구 혹은 불안 회피와 밀접하게 관련된 안정적 성격(Behavioral Activation System-BAS 혹은Behavioral Inhibition System-BIS)의 개인차에 의해 유의미하게 예측될 수 있음이 나타났다. 이러한 결과는 그동안 외현적인 재인 기억 의사 결정에 있어서 중요하게 여기지 않았던 점증적 강화학습 기제가 결정 준거의 설정에 관여할 수 있음을 보여준다는 데에서 중요한 의미를 찾을 수 있다.

  • 본 연구는 여대생들 간의 메이크업에 대한 관심과 인지도 파악하고자 메이크업에 대한 의식 조사를 통하여, 인식유형별로 메이크업에 따른 심리와 선호하는 메이크업 패턴을 조사였다. 메이크업이 개인에게 정서적으로 자신감과 긍정적 사고를 하는데 도움을 주며, 타인에 대한 사회적 예의의 한 범주라고 생각하였다. 메이크업 인식 차이에 따른 대상의 그룹핑은 이미지 관조군 수용군 관망군 대응군으로 분류 할 수 있었다. 인식 차이에 따른 4가지 유형의 메이크업 관심도는 세부적으로 약간의 차이는 있었으나 메이크업 행위가 대인관계 형성 시 높은 필요도를 차지하고 있었으며, 메이크업 패턴은 피부 톤을 중요시하는 자연스러운 스타일을 선호하였다. 이처럼 현재 뷰티 트렌드의 시장의 주 고객층을 형성하고 있는 20대 여대생의 메이크업에 관한 설문조사를 한 결과 트렌드 메이크업 행위에 대한 관심도와 인지도를 파악할 수 있었으며, 본 연구의 결과를 뷰티 트렌드 개발과 마케팅에 적극 활용하면 다양하고 효과적인 미용문화를 창조할 수 있을 것으로 사료된다.
