  • Since self-efficacy was suggested by Bandura(1977) as the most important factor that affects human behavior, preceding studies about self-efficacy are frequently related with children, and it is a main stream that only personal factors are chosen as related factors of these studies. Considering we don't have enough studies about family factors that reflect qualitative and relational factors of adolescents' home background, this study was aimed to seize the actual condition of self-efficacy meaning perceived and emotional faith about their own ability. These are our major concerns: 1. What kind of tendency does self-efficacy and appearance stress of adolescents, family functioning show? 2. How strong are relative influences of variables on self-efficacy of adolescents? This study was operated on July and August, 2002, aimed 378 middle school and high school students in Jeon-Nam, Mokpo area. 378 question sheets were used for analysis. Followings are results of this study. First, aimed students' average mark of self-efficacy was 2.09, which meant a normal level. And in low-ranked part, self-control-efficacy was the highest, and confidence task difficulty preference was following. Furthermore, whole self-efficacy showed a little difference from the demographic factor of adolescents. In low-ranked part, however, confidence and self-efficacy showed a somewhat difference. As students grew up, confidence decreased, and male students showed higher self-control-efficacy than female ones. Second, appearance stress and family functioning degree had a strong relation with self-efficacy. Family functioning, had important interrelation not only with whole self-efficacy but also with low-ranked part of self-efficacy. In low-ranked part, self-control-efficacy and task difficulty preference were proportional to the family functioning degree. From these results, we can find that the appearance stress was an actual factor that affected the self-efficacy of adolescents, and their self-efficacy was strongly related with family functioning degree. Accordingly, affirmative emotion in family, harmonic communication among family members and sharing housekeeping works had an immediate influence on elevation of self-efficacy.

  • This study is designed to find out the effect of communication between parents and adolescents, and their goal orientation on academic self-efficacy, especially among second-year high school students based on all their family and social environments. For such purposes, a variety of data regarding background variables, communication between parents and adolescents, goal orientation, and academic self-efficacy were collected in Seoul and Goyang-si, Gyunggi-do. The major results of this study are as follows: First, the female high-school students showed a higher efficiency than the male ones when it comes to the communication between parents and adolescents. For the goal orientation, the girl students marked higher levels than the male counterparts; speaking of self-regulated efficiency, the former illustrated a much higher level than the latter as well. Second, academic self-efficacy is greatly influenced by goal orientation. The higher mastery and performance-approach goals are, the higher academic self-efficacy is. It has turned out that mastery goals have significant relationship with task difficulty performance, one of the sub-scales of academic self-efficacy. In addition, performance-approach goals proved to be deeply connected with self-regulated efficiency, but performance-avoidance goals were negative predictors of task difficulty performance and self-regulated efficiency. In turn, academic confidence, one of the sub-scales of academic self-efficacy, is believed to be under the influence of mastery goals and communication between fathers and adolescents.

  • 본 연구에서는 P300-기반 숨긴정보검사(P300 CIT)에서 검사자극들 간의 물리적 유사성이 P300 진폭과 검사의 효율성에 미치는 영향을 검증하였다. 사고를 당하여 자신의 이름을 기억하지 못한다고 허위로 주장하는 허위기억상실을 가정한 상황에서, 실험참여자의 이름을 숨긴정보(관련자극)로 사용하여 P300 CIT를 실시하였다. 이 검사에서 실험참여자의 과제는 목표자극과 나머지 자극을 변별하는 것이었다. 한 집단의 실험참여자들은 목표자극과 관련자극, 무관련자극들 간의 물리적 유사성이 낮은 조건(저난도 조건)에서 검사를 받았으며, 다른 한 집단의 실험참여자들은 검사자극들 간의 물리적 유사성이 높은 조건(고난도 조건)에서 검사를 받았다. 기저선-정점 P300 진폭을 측정치로 사용한 경우, 난이도 조건과 자극유형의 상호작용효과가 $\alpha$=.10 수준에서 유의하였다(p=.052). 저난도 조건에서는 관련자극과 무관련자극 간의 P300 진폭차이가 유의하였으며, 고난도 조건에서는 관련자극과 무관련자극 간의 P300 진폭차이가 유의하지 않았다. 정점-정점 P300 진폭을 측정치로 사용한 경우, 난이도 조건과 자극유형의 상호작용효과가 유의하지 않았으며, 저난도 조건과 고난도 조건 모두에서 관련자극과 무관련자극간의 P300 진폭차이가 유의하였다. 기저선-정점 P300 진폭을 이용한 개인별 판단결과, 저난도 조건과 고난도 조건 간의 정확판단율 차이가 유의하지 않았으며, 정점-정점 P300 진폭을 이용한 개인별 판단결과도 저난도 조건과 고난도 조건 간의 정확판단율 차이가 유의하지 않았다. 그러나, 난이도 조건 간의 정확판단율 차이가 기저선-정점 P300 진폭을 이용한 경우보다 정점-정점 P300 진폭을 이용한 경우에 더 작은 경향이 있었다. 이러한 결과는 검사자극들 간의 물리적 유사성이 높을 때에도 P300 CIT의 효율성이 크게 감소하지 않는다는 것을 의미한다.

  • Although atypical sensory processing is a core feature of autism spectrum disorder (ASD), there is considerable heterogeneity among ASD individuals in the modality and symptoms of atypical sensory processing. The present study examined visual processing of children with ASD, focusing on the complexity and orientation of visual information. Age- and -IQ-matched Korean children (14 ASD and 14 typically-developing (TD) children) received an orientation discrimination task involving static spatial gratings varied in complexity (simple versus complex) and orientation (horizontal versus vertical). The results revealed that ASD children had difficulty perceiving complex information regardless of orientation, whereas TD children had more difficulty with vertical gratings than horizontal gratings. Thus, group-level differences between ASD and TD children appeared greater when gratings were presented horizontally. Unlike ASD adult literature, however, ASD children did not show superior performance on simple gratings. Our findings on typical and atypical processing of ASD children have implications for both understanding the characteristics of ASD children and developing diagnostic tools for ASD.

  • Objective : This study grasps specific task on paramedics who plays a great role in the emergency scene, thereby eliciting definition of job called paramedics and analyzing occupation by DACUM method. Thus, the aim is to suggest working-level guidelines on the task of paramedics. Methods : It targeted paramedics who are working at hospitals, fire stations, and industries in Seoul and Gyeonggi area from Oct. 11, 2010 to Nov. 30. A total of 608 copies of questionnaire were analyzed by DACUM method. A research tool on occupational analysis consisted of 8 pieces for duty, 43 pieces for task, and 149 pieces for task elements. In order to survey performance frequency, importance, and difficulty by element, each task was developed by this research team, and each task was analyzed and finally elicited through workshop of DACUM method. Results : The occupational definition of paramedics, which was defined through this DACUM, was elicited as 'professional job of performing emergency medical care on the scene, during transferring, or within medical institution in order to maintain life and prevent wound deterioration, targeting a person who is put in emergency situation.' Task element, whose performance frequency was indicated to be the highest, was in order of checking mental status($2.76{\pm}0.497$), checking vital signs($2.70{\pm}0.578$), and airway/c-spine immobilization($2.69{\pm}.546$). Especially, defibrillation stood at $2.23{\pm}.655$ points. Task element, whose performance frequency was low, was in order of caring sexual abuse victims($1.32{\pm}0.563$), performing cricothyrotomy($1.36{\pm}0.618$), and caring cardiac arrest victims($1.40{\pm}0.636$). Importance of task was in order of airway/c-spine immobilization ($2.88{\pm}0.338$), maintenance of respiration($2.88{\pm}0.351$), caring cardiac arrest victims($2.87{\pm}0.349$), and performing CPR($2.87{\pm}0.361$). Task element, whose importance is low, was indicated to be in order of enema($2.29{\pm}0.736$), urinary catheterization($2.35{\pm}0.664$), and nasogastric intubation($2.35{\pm}0.667$). Task element, whose difficulty was shown to be the highest, was indicated to be in order of caring cardiac arrest victims during pregnancy ($2.60{\pm}0.559$), caring cardiovascular injury($2.59{\pm}0.546$), and labor management($2.53{\pm}0.533$). Conclusion : Based on the results of this study, the job performance work table(Dacom chart) of paramedics is suggested to be used, thereby being applied to development in education and curriculum of paramedics. It is necessary to evaluate usefulness of the job performance work table by estimating effect of education for paramedics based on the job performance work table of paramedics.

  • A multichannel smart sound sensor capable to detect and identify sound events in noisy conditions is presented in this paper. Sound information extraction is a complex task and the main difficulty consists is the extraction of high­level information from an one-dimensional signal. The input of smart sound sensor is composed of data collected by 5 microphones and its output data is sent through a network. For a real time working purpose, the sound analysis is divided in three steps: sound event detection for each sound channel, fusion between simultaneously events and sound identification. The event detection module find impulsive signals in the noise and extracts them from the signal flow. Our smart sensor must be capable to identify impulsive signals but also speech presence too, in a noisy environment. The classification module is launched in a parallel task on the channel chosen by data fusion process. It looks to identify the event sound between seven predefined sound classes and uses a Gaussian Mixture Model (GMM) method. Mel Frequency Cepstral Coefficients are used in combination with new ones like zero crossing rate, centroid and roll-off point. This smart sound sensor is a part of a medical telemonitoring project with the aim of detecting serious accidents.
