The aim of this study was to investigate the relationship between the oral health status of elderly under visiting health care and their oral health-related quality of life. The subjects were 300 elderly under visiting health care program over 65 years old in Asan city and they were interviewed. The result showed that average Geriatric Oral Health Assessment Index (GOHAI) score was 37.36 and the lowest scored question was 'never satisfied with the oral condition'. In GOHAI related to oral health behaviors, unmet dental treatment experience was statistically significant (p<0.001). In overall GOHAI, number of remaining teeth (p<0.001) and the age had statistical significance and men had higher score in pain and discomfort (p<0.05), under age of 74 limited function factors score was high (p<0.01). The number of remaining teeth had statistical significances in most factors except pain and discomfort (p<0.001). The factors affecting GOHAI were age (p<0.05), number of remaining teeth (p<0.001) and perceived health state (p<0.001). In order to improve oral health-related quality of life of elderly receiving visiting oral health care services, it is necessary to increase denture support by securing budgets and developing oral health promotion programs at the local government level.

The significant role of joint attention in the development of children with autism spectrum disorder (ASD) has highlighted the importance of early intervention. With the emphasis on the effective cueing and reinforcer for orienting to social stimuli in improving responding to joint attention (RJA) of children with ASD, the use of musical cue was hypothesized. This study aimed to examine the occurrence of RJA behaviors depending on the attentional cue, which differed in the level of information and type of auditory modality. Nine children with ASD participated in this study. The use of eight different joint attention cues were analyzed in terms of the frequency and accuracy of RJA behaviors elicited. The results of the study showed that RJA behaviors occurred more frequently with musical cues than with verbal cues and the mean accuracy rate of RJA was higher with musical cues (p = .047). Musically delivered eliciting and directing cues accompanied with pointing elicited the highest attentional shift and RJA accuracy. The significant increases in RJA with the use of musical cues indicated that incorporating musical elements into an attentional cue may provide more accurate cue information, enough to improve RJA behaviors of children with autism.

Human beings in their perception of the objects perceive the overall characteristics first rather than any parts of the object. In the process of 'information structuralization' and 'information visualization', therefore, it is needed the methods of narrative information representation based on a relationship of cause and effect in order to express effectively the whole messages which designers want to deliver. In this study, according to the concept of narrative information representation, we reviewed the meanings of the visual storytelling. As a result, we found that the visual storytelling has the three key roles which are 'narrative', 'visual communication catalyst', 'interacting'. First, the narrative describes the information logistics flow and it has a role to provide a specific story into information in the process of users' information understanding. Second, in the information design, the visual story telling not only expresses the information structure(story) but also uses the visual expressions to deliver the specific message, which is called visual communication catalyst. Third, the information design goes through the information structuralization and the information visualization stages through the visual storytelling to provide the experience factors to the information users, which is called the interactivity. The research implication is to provide the basis developing an approach method which is able to convey information messages effectively by improving information users' visual cognition and raising information users' memory.

현재까지 미생물의 증식을 억제하는 보존제로는 인공합성품이 많이 알려져 이들이 주로 상업적으로 사용되고 있으나 그 안정성이 경우에 따라 문제되고 있으며 근래소비자의 건강 지향적 욕구가 증대됨에 따라 인공합성품의 기피현상이 두드러지고 있다. 따라서 이들 천연 항균물질의 개발과 이용은 인공 합성보존제의 대처라는 의미와 소비자기피현상을 유발시키지 않으면서 각종 가공식품의 저장성향상 및 저온 유통식품의 안정성확보라는 견지에서 그 중요성이 있다. 본 실험에서는 식품의 미생물 작용에 의한 변질의 저해 효과가 뛰어난 식물성천연항균제품(Botanical antimicrobial agents-Citrus product : 이하 BAAC라 칭함)에 천연보조제(Ginseng extract, Aloe, 매실추출물)를 첨가하여 Paper disk 법에 의한 항균성 검사를 실시한 결과 Ginseng extract를 첨가한 경우 생육저해환이 가장 크고 뚜렷하게 나타났다. 따라서 BAAC에 보조제(Ginseng extract)를 첨가하여 제조 된 천연 항균복합제재(이하 BAAG라 칭함)를 우유에는 각 농도별로 첨가하여 4$^{\circ}C$의 냉장상태와 2$0^{\circ}C$의 상온에서 저장하였고, 계란과 콩나물의 경우는 침지 처리한 후 꺼내어 상온에서 저장하면서 각각 주사전자현미경 관찰, 대장균수, 총균수의 변화, 외관상의 변화에 미치는 영향을 무처리 대조구와 비교하면서 조사하였다. 아울러, 계란의 경우는 조단백함량의 변화도 관찰하였다. 주사전자현미경 촬영사진의 결과 분석을 통하여 BAAG를 처리한 균체 세포는 세포막 및 세포벽 기능이 파괴되어 세포내용물이 균체외부로 유출되어 균체의 생육이 억제되며 성장을 저해 또는 사멸시키는 것으로 나타났다. 대장균수는 우유, 달걀 및 콩나물의 모든 처리구에서 BAAG의 첨가에 의해 성장이 억제되었으며 농도가 증가시킬수록 균증식 억제 효과가 뚜렷하였으며, 총균수도 압도적으로 낮은 간을 보여주었다. 달걀의 조단백함량의 변화는 BAAG를 처리하지 않은 무처리 대조구에 비하여 침지 처리한 경우가 조단백 변화가 크지 않았다. 즉, BAAG의 침지 처리한 경우, 저장기간 14일이 경과 한 후에 10%정도의 수준으로 감소한데 반하여, 무처리구인 대조구의 경우, 23%수준으로 감소 증도가 증가하였다. 외관상의 변화와 상품 가치를 측정한 결과는 달걀의 경우, 14일이 경과후에는 무처리 대조구에서 흰자위의 감소와 노른자위와의 경계가 뚜렷하지 못하여 상품으로서의 가치가 크게 떨어진 상태였다. 우유의 경우에는 4$^{\circ}C$와 2$0^{\circ}C$에 저장된 대조구에서는 각각 3일과 12일경과 후 강한 부패취와 아울러, 표피의 갈변정도가 심하되어 관능적으로 부패상태를 인지할 수 있었다. 콩나물의 경우도 저장3일 경과 후에 부패취와 함께 점질성 갈변물질이 생성되었다. 이와 같은 결과로 볼 때, BAAG의 처리는 BAAC의 경우보다 가격은 저렴하면서도 항균력은 우수한 천연 항균복합제재로써 농산물 식품원료에 적용하여 선도유지 기간을 연장할 수 있는 효과를 기대할 수 있었다.

In this paper, we propose the development of MHLA(Modulatory Hippocampus Learning Algorithm) which remodel a principle of brain of hippocampus. Hippocampus takes charge auto-associative memory and controlling functions of long-term or short-term memory strengthening. We organize auto-associative memory based 3 steps system(DG, CA3, CAl) and improve speed of learning by addition of modulator to long-term memory learning. In hippocampal system, according to the 3 steps order, information applies statistical deviation on Dentate Gyrus region and is labelled to responsive pattern by adjustment of a good impression. In CA3 region, pattern is reorganized by auto-associative memory. In CAI region, convergence of connection weight which is used long-term memory is learned fast by neural networks which is applied modulator. To measure performance of MHLA, PCA(Principal Component Analysis) is applied to face images which are classified by pose, expression and picture quality. Next, we calculate feature vectors and learn by MHLA. Finally, we confirm cognitive rate. The results of experiments, we can compare a proposed method of other methods, and we can confirm that the proposed method is superior to the existing method.

Recently, users want to use real-time multimedia services, such as internet, VoIP, etc., using their IEEE 802.11 wireless lan mobile stations. In order to provide such services, a handoff among access points is essential to support the mobility of a node, in such an wide area. However, the legacy handoff methods of IEEE 802.11 technology are easy to lose connections. Also, the recognition of a disconnection and channel re-searching time make the major delay of the next AP to connect. In addition, because IEEE 802.11 decides the selection of an AP depending only on received signal strength, regardless of a node direction, position, etc., it cannot guarantee a stable bandwidth for communication. Therefore, in order to provide a real-time multimedia service, a node must reduce the disconnection time and needs an appropriate algorithm to support a sufficient communication bandwidth. In this paper, we suggest an algorithm which predicts a handoff point of a moving node by using GPS location information, and guarantees a high transmission bandwidth according to the signal strength and the distance. We implemented the suggested algorithm, and confirmed the superiority of our algorithm by reducing around 3.7ms of the layer-2 disconnection time, and guaranteed 24.8% of the communication bandwidth.

This study has an objective of suggesting the ways to improve infant's sense of self-respect and peer competence, by examining what effect infant temperament has on infant's sense of self-respect and peer competence. The notable study results through analysis are as follows; First, it was shown that, in regard with adaptability and activity of infant temperament, cognitive ability of the sense of self-respect and peer acceptance, the average score of day care centers was higher, while it was shown that, in regard with response of infant temperament, the sense of self-respect's mother acceptance, peer relationship, sociability of peer competence, the average score of kindergartens was higher, and the boy infants' physiological regularity was shown to be higher than that of girl infants. Second, as a result of looking into the difference of infant temperament, sense of self-respect, and peer competence according to infant's age, we found that, in case of 'response' of infant temperament, age 5 group was classified into 'group a', and age 3 and 4 group was classified into 'group b', and two groups showed the difference, and in case of 'physiological regularity', age 3 group had the biggest regularity while age 5 group had the relatively low regularity, thus two groups showed the difference. In regard with sense of self-respect and peer competence, it was shown that age 4 and 5 group had higher one than that of age 3 group.

This study has significance in terms of its intent to contribute to the increase in hospital revisits by proposing measures to enhance name awareness through an examination of the relationship between the name awareness of public medical institutions and patients' revisit, and its corresponding influences. The study findings were drawn by employing analysis methods such as frequency analysis, reliability and exploratory factor analysis, t-tests, ANOVA, correlation analysis, and hierarchical multiple regression analysis. The results of the correlation analysis showed statistically significant correlations between all independent variables and the patients' revisit or not. The perception of service quality and the environmental factor of medical treatment increased the explanatory power of independent variables, thereby exhibiting a high correlation with the revisit to medical institutions. The usual image, medical service, and medical treatment environment were revealed to have a positive influence on the patient's intent to revisit. This study could confirm a correlation between the name awareness of medical public institutions and the patients' revisit or not. Consequently, to improve the quality and infrastructure of their medical services, public medical institutions are required to perform studies on measures to increase the revisits of patients by identifying their image, medical services, and treatment environment on a consistent basis.
