This study investigates the differences in the purchasing behavior of infant and children's wear with particular attention to the features of children and consumers. This study conducted a survey on female buyers of infant and children's wear living in Seoul and Gyeonggi Province. A total of 558 questionnaires were analyzed using a SPSS 18.0 statistic program with factor analysis, Cronbach's ${\alpha}$, cluster analysis, ANOVA, and Duncan test. The results are as follows. 1. Three types of groups by values were identified: mental-social achievement oriented group, social achievement oriented group, and pleasure value oriented group. 2. A significant difference was found in the physical criteria and aesthetic criteria. 3. A significant difference was found among the relation of groups in fancy, neat, and easy-active images. 4. The results showed for all groups that consumers of infant and children's wear prioritized soft pastels most.

전하 결함 소자를 이용한 16×16 이차원 영상 감지 소자가 제작되었다. 제작된 소자는 2상(two-Phase)의 전극 구조로 제작 되었고 프레임 이동(frame transfer) 방식으로 동작한다. 표면 전위차를 얻기위해 이온 주입을 했고 NMOS공정을 따라 제작되었다. 영상을 얻기위한 시스템은 광학 렌즈 클럭 발생 및 구동 회로, 계단형 신호 발생기로 이루어지는데, EPROM을 사용하여 클럭 발생회로를 간단하게 하였다. 영상 시스템을 사용하여 오실로스코프 화면에 알파베트를 표시할 수 있었다. 소자의 특성으로 전하 이동 손실률과 암전류를 측정하였다.

Constant technological developments in coronary artery disease have contributed to the assessment of both the presence of coronary stenosis and its hemodynamic consequences. Hence, noninvasive imaging helps guide therapeutic decisions by providing complementary information on coronary morphology and on myocardial perfusion and metabolism. This can he done using single photon emission computed tomography (SPECT) or positron emission tomography (PET) and multidetector CT (MDCT). Advances in image-processing software and the advent of SPECT/CT and PET/CT have paved the way for the combination of image datasets from different modalities, giving rise to hybrid imaging. Three dimensional cardiac hybrid imaging helped to confirm hemodynamic significance in many lesions, add new lesions such as left main coronay artery disease, exclude equivocal defects, correct the corresponding arteries to their allocated defects and identify culprit segment. Cardiac hybrid imaging avoids the mental integration of functional and morphologic images and facilitates a comprehensive interpretation of coronaty lesions and their pathophysiologic adequacy by three dimensional display of fused images, and allows the best evaluation of myocardial territories and the coronary-artery branches that serve each territory. This integration of functional and morphological information were feasible to intuitively convincing and might facilitate development of a comprehensive non-invasive assessment of coronary artery disease.

최근 네비게이션 시스템이 대중화되면서 랜드마크 연구는 도시지역 이동을 위한 인지적 시스템 개발에 중요한 연구주제가 되고 있다. 지역 커뮤니티에게 있어서 랜드마크로 구성된 도시이미지는 지역 네비게이션에 있어서 장소인식을 위한 참조프레임 역할을 담당한다. 일반적으로 네비게이션은 새로운 지역을 이동하는 탐험(Exploration)과 친숙한 지역을 이동하는 네비게이션으로 구분할 수 있다. 후자의 경우, 도시이미지는 지역 커뮤니티에게 있어서 장소인식에 있어서 핵심적인 역할을 담당한다. 커뮤니티의 장소인식은 시스템적으로 연결된 장소들로 구성된 도시이미지에 기반을 두어 이루어지는 지식기반의 추론의 과정이다. 본 연구에서 도시이미지의 구조는 계층적 지식으로 간주하여 커뮤니티를 위한 지역이동을 위한 도메인 온톨로지로 표현하였다. 커뮤니티에게서 수집된 도시이미지는 커뮤니티의 인지정도에 따라 엥커(anchor), 디스턴트(distant)와 로컬(local)분류하였다. 온톨로지 모델링 기법을 이용한 도시이미지의 표현은 지역 커뮤니티의 지리적 지식으로 명시화하고 도시지역 안내를 위한 에이전트를 위해 재사용이 가능한 지식으로서 유용한 의미를 갖는다.

The present study aims at investigating the relationship between voices and the physical images triggered by the voices. It is the final part of a four-part series and the results reported in the present study are limited to those of American speakers and American listeners. Combined with the results from previous studies (Moon, 2000; Moon, 2002; Tak, 2005), the results suggest that (1) there is a very strong, much higher than chance-level relationship between voices and the pictures chosen for the voices by the perception experiment subjects; (2) the more physical characteristics that are given, the better the chance for correctly matching voices with pictures; and (3) culture (in the present, language environment) seems to play a role in conjuring up the mental images from voices.

The goal of this paper is to understand the visual information process and the characteristics of behaviour of the architectural design process using visual protocol analysis through the actual experiment by the architect. The visual protocol analysis is developed on the basis of the theories of the visual information processing model and visual mental image, which can explain visual representation in architectural design process. A protocol study is reported in which the experimental data by architect is analyzed through the protocol analysis method. The whole design process is divided into the stage of 9 tasks which are classified into 18 visual representatiov. The results about visual cognition in cognitive science are reviewed and summarized, and these findings will help understand the architectural design nature.

Vision-based systems for finding road lanes have to operate robustly under a wide variety of environ-mental conditions including large amount of scene clutters. This paper presents a method for finding the lane boundaries by combining a local line extraction method and dynamic programming as a search tool. The line extractor obtains an initial position estimation of road lane boundaries from the noisy edge fragments. Dynamic programming then improves the initial approximation to an accurate configuration of lane boundaries. Input image frame is divided into a few sub-regions along the vertical direction. The local line extractor then performs to extract candidate lines of road lanes in the...

In this paper, Depression is a mental disorder characterized by a lack of enthusiasm and feelings of sadness, which significantly impairs daily functioning. In 2018, there was an increase in book sales in the essay genre, particularly the popularity of "healing essays." This trend is seen as challenging the negative image and prejudices associated with depression. In 2021, a significant rise in the proportion of 20-year-old patients with depression is attributed to factors like job-related stress, interpersonal issues, and financial burdens. Additionally, there is a strong correlation between depression and suicidal thoughts, particularly among individuals who have experienced feelings of depression. Despite the increasing prevalence of depression among young adults, research in this area is lacking. To address this gap, statistical tools such as logistic regression and chi-squared tests are employed. The analysis reveals various independent variables associated with feelings of depression, shedding light on the relationships between these factors.

A 12-year-old spayed female Yorkshire terrier dog was presented with two-weeks history of lethargy, mental dullness and polydipsia. Neurologic examination revealed proprioceptive defect of all limbs and loss of swallowing gag reflex. The dog revealed persistent dehydration, hypernatremia, hyperosmolarity and hyposthenuria. On magnetic resornance imaging (MRI), the mass were heterogeneous signality on T1 weighted images, hyperintense signality on T2 weighted image with contrast enhancement on hypothalamohypophyseal lesion. Based on these findings, the dog was suspected as having pituitary gland tumor. Through water deprivation test and response to desmopressin acetate (1-deamino-8-D-arginine, DDAVP), this case was diagnosed by central diabetes insipidus (CDI). This paper reports the clinical sign, MRI, response to the exogenous antidiuretic hormone of CDI due to suspected pituitary tumor in a dog and DDAVP administration was evaluated effective therapy to correct hypernatremia induced by CDI.

Objectives: The purpose of this study was to identify factors affecting self-worth and social competence among middle school students. Methods: The survey collected 388 subjects from 2 middle school students in Seoul, Korea. Data were analyzed with $t^2-test$, ANOVA and regression analysis. Results: First, self-worth were significantly different by academic grades. Also social competence were significantly different by academic grades. Second, it showed the effect of regular exercise and endurance on self-worth. Third, it showed the effect of external image, health, regular exercise and endurance on social competence. Conclusions: It was suggested to develop physical, mental and social health programs and policies were required for development of physical self-concept, self-worth and social competence.
