The purpose of this study was to test the revised Health Promotion Model of Pender and to determine the factors to promote health behavior for adolescents' smoking behavior. The subjects of the study was 783 boys of 4 high school students. among 39. schools locating in Daejeon metropolitan city. The data was collected from July 1st to 15th. 1997 by school health nurse The research tool were HPLP of Walker. Pender. General self-efficacy scale of Sherer. control scale was measured by subconcept of hardiness scale of Pollock. and perceived barrier. perceived benefit. activity-related-affect tool were made by researcher via literature review The data were analyzed by SAS program using frequency. t-test. ANOVA. Schefee test. regression. The results were as follows 1. The mean of total health promoting behavior was $2.27\pm.35$. Among sub domain of health promoting behavior, the highest score was interpersonal support$(2.72\pm.60)$. and the lowest was health responsibility $(1.58\pm.44)$. 2. There were statistically significant difference in total health promoting behavior according to religion. parenting style. school performance. girl friend. father's smoking of individual characteristics. 3. The socioeconomic status. smoking, parent pattern. family structure of individual characteristics and experience domain associated with perceived benefit. perceived barrier. activity-related affect. interpersonal influence of behavior-specific cognition and affect domain. The perceived barrier. self-efficacy. girl friend and father's smoking of interpersonal influence. and control explained $25.8\%$ of variance of health promoting behavior. From above results school health nurse has to emphasize on health responsibility for health promotion of adolescent. But they couldn't intervene for parent pattern. socioeconomic status. family structure of individual characteristics and experience domain. it could be possible for school health nurse to promote health of adolescents through improving perceived barrier. also develop program to increase self-efficacy and through parent health class for fathers. Above results point to the importance of including parents in smoking prevention effort targeting adolescents. Because increasing control also promotes health of adolescents. it should be studied further about the specific measure. To verify the variables for increasing the fitness of health promoting model. it needs further replication of the research.

최근 MANET(Mobile Ad-Hoc Network)에서 보안요소를 추가한 라우팅 연구가 활발히 진행되어왔다. 그러나 기존 연구들은 secure 라우팅 또는 패킷 자체에 대한 악의적인 행위 탐지 중 어느 한 측면에 대해서만 연구가 되어왔다. 본 논문에서는 패킷 자체에 대한 악의적인 행위 및 라우팅 측면에서 보안 요소를 모두 고려한 SRPPnT(A Secure Routing Protocol in MANET based on Malicious Pattern on Node and Trust Level)를 제안한다. SRPPnT는 악의적인 행위가 이루어진 노드를 확인하여 각 노드에 대한 신뢰수준을 측정 후, 획득한 각 노드의 신뢰수준에 따라 라우팅 경로를 설정함으로써 패킷 및 라우팅 경로 설정에 대해 이루어질 수 있는 악의적인 행위를 효율적으로 대응할 수 있다. SRPPnT는 AODV(Ad-Hoc On-Demand Distance Vector Routing)를 기반으로 하였다. NS 네트워크 시뮬레이션 결과를 통해, 제안된 SRPPnT는 기존 프로토콜보다 네트워크 부하를 감소시킨 상태에서 악의적인 노드의 보다 정확하고 신속한 식별과 secure한 라우팅이 이루어짐을 확인하였다.

Structural Control relies, with a great deal, on the ability of the control algorithm to identify the current state of the system, at any given point in time. When such algorithms are designed to perform in a smart manner, several smart technologies/devices are called upon to perform tasks that involve pattern recognition and control. Smart pattern recognition is proposed to replace/enhance traditional state identification techniques, which require the extensive manipulation of intricate mathematical equations. Smart pattern recognition techniques attempt to emulate the behavior of the human brain when performing abstract pattern identification. Since these techniques are largely heuristic in nature, it is reasonable to ensure their reliability under real life situations. In this paper, a neural network pattern recognition scheme is explored. The pattern identification of three structural systems is considered. The first is a single bay three-story frame. Both the second and the third models are variations on benchmark problems, previously published for control strategy evaluation purposes. A Neural Network was developed and trained to identify the deformed shape of structural systems under earthquake excitation. The network was trained, for each individual model system, then tested under the effect of a different set of earthquake records. The proposed smart pattern identification scheme is considered an integral component of a Smart Structural System. The Reliability assessment of such component represents an important stage in the evaluation of an overall reliability measure of Smart Structural Systems. Several studies are currently underway aiming at the identification of a reliability measure for such smart pattern recognition technique.

Ultra-high performance concrete (UHPC) is one of the most promising construction materials because it exhibits high performance, such as through high strength, high durability, and proper rheological properties. However, it has low tensile ductility compared with other normal strength grade high ductile fiber-reinforced cementitious composites. This paper presents an experimental study on the tensile behavior, including tensile ductility and crack patterns, of UHPC reinforced by hybrid steel and polyethylene fibers and incorporating plastic beads which have a very weak bond with a cementitious matrix. These beads behave as an artificial flaw under tensile loading. A series of experiments including density, compressive strength, and uniaxial tension tests were performed. Test results showed that the tensile behavior including tensile strain capacity and cracking pattern of UHPC investigated in this study can be controlled by fiber hybridization and artificial flaws.

The aims of this study are to classify the life styles of urban housewives, to see their relationship between life style and demorgaphic variables, and also to see the relationship between life style and dietary patterns. This study has been performed by a questionsire about life style, demographic variables and dietary pattern. The selected samples were 475 housewives. The data were analyzed by factor analysis, cluster analysis, Duncan test, X-test and F-test. Life style is classified into 4 types: temporary enjoying type, passive irrational type, realistic conservative type, actual progressive type. The housewives who are in temporary enjoying type usually do randomly and don't think seriously something. And they have tendency to enjoy themselves. Therefore they don't have any plan for dietary behavior. The passive irrational type's housewives have no consistancy in their life and they do everything temporarily. The housewives who are in this type have relatively low incom, low level of education and they are high in age. The people who are in realistic conservative type act reasonably and elastically everything. They use convenient food very much, because they are willing to save time to make them. The housewives who are included in actual progressive type are well organized and planned in dietary behavior than others, when they dine out, they eat with family together in general, they usually use only a kind of western sauces and convenient food. They are relatively young, highly educated, and they are high income group. In conclusion realistic conservative type and actual progressive type are both relatively desirable type in dietary behavior, but in temporary enjoying type and passive irrational type, there, have to do some guide and education about managing family resources and dietary behavior.

The purpose of this study was to analyze behavioral patterns of elderly residents and to identify the characteristics of using furniture and home appliances by elderly-headed households. For this purpose, field studies that included observation and open-ended interview were conducted with 52 elderly-headed households. The major findings of this study were as follows: elderly-headed households need home appliances with lighter body, lower capacity and simple functions. Furniture for elderly people should be designed to minimize the inconvenience of using western style furniture, also the behavior patterns which are important to the elderly like taking medicine have to be considered. And it is necessary to design furniture and equipments properly to prevent accidents happened in housing. Lastly, because the elderly relies heavily on watching TV, it will be desirable to apply TV-friendly devices such as home networking and home automation. Research results will be useful information on product design to reflect characteristics of elderly and follow-up studies associated with each furniture and appliances and specific living behavior are needed.

Nanoimprint lithography (NIL) process at room temperature has been newly proposed in recent years to overcome the shape accuracy and sticking problem induced in a conventional NIL process. Success of the room temperature NIL relies on the accurate understand of the mechanical behavior of the polymer. Since a conventional NIL process has to heat a polymer above the glass transition temperature to deform the physical shape of the polymer with a mold pattern, viscoelastic property of polymer have major effect on the NIL process. However, rate dependent behavior of polymer is important in the room temperature NIL process because a mold with engraved patterns is rapidly pressed onto a substrate coated with the polymer by the hydraulic equipment. In this paper, finite element analysis of the room temperature NIL process is performed with considering the strain rate dependent behavior of the polymer. The analyses with the variation of imprinting speed and imprinting pattern are carried out in order to investigate the effect of such process parameters on the room temperature NIL process. The analyses results show that the deformed shape and imprint force is quite different with the variation of punch speed because the dynamic behavior of the polymer is considered with the rate dependent plasticity model. The results provide a guideline for the determination of process conditions in the room temperature NIL process.

This study was conducted to investigate the food behavior during the childhood, the influence of food behavior on internalizing and externalizing behavior problems, and the pattern of influence of food behavior on behavior problem depending on children's age and gender. A total of 171 children aged 5 and 6 years were selected who attended 3 nurseries and 1 kindergarten in Seoul, and the survey data responded by teachers were analyzed. The results were as follows. First, children with higher levels of food behavior showed less internalizing behavior problems compared to those with lower levels of food behavior. The main effects and interaction of gender and age were not significant. Second, children with higher levels of food behavior showed less externalizing behavior problems compared to those with lower levels of food behavior. For hyperactivity, interaction of age and food behavior was significant, and age and the interaction of age and food behavior affected children's agression. Food behavior of children affects behavior problem and, therefore, children with better food behavior showed less behavior problems in the same circumstances.

Objectives : Recurrence of mood episodes associated with a specific season has been described in various mood disorders. Seasonal change in mood and behavior as a lifetime trait is also observed in healthy individuals. This study aimed at comparing the lifetime trait of seasonal variations of mood and behavior between bipolar disorder patients and controls as well as investigating associated factors of seasonality. Methods : Subjects were ninety-four clinically stable patients with bipolar disorder and 188 age- and sex-matched healthy controls. Seasonality of mood and behavior was assessed retrospectively on lifetime basis using Seasonal Pattern Assessment Questionnaire(SPAQ). Results : The patient group showed a higher median global seasonality score(GSS) of SPAQ and a higher rate of seasonal affective disorder(SAD) compared to the control group(p < 0.0001). For subjects showing prominent seasonality, the seasonal symptom profile and seasonal pattern was similar in both patient and control groups. In addition to the diagnosis, female gender was shown to be a predictor of seasonality in the multiple linear regression analysis(p = 0.045). Conclusion : This study suggests that lifetime trait of seasonality may be related to the susceptibility of bipolar disorder.
