본 연구는 청소년이 바람직한 사회구성원으로서 성장하기 위해 필요한 요소로서 타인에 대한 배려와 돌봄의 행위인 친사회적 행동에 주목하였다. 또래집단의 영향이 청소년의 친사회적 행동에 어떻게 작용하고 있는지 알아보기 위해 또래영향모델과 개인특성모델을 중심으로 분석하였다. 보건복지부의 '아동청소년종합실태조사' 자료를 위계적 다중회귀분석으로 검증한 결과, 청소년의 친사회적 행동은 친구의 친사회적 행동으로부터 긍정적인 영향을, 친구의 반사회적 행동으로부터 부정적으로 영향을 받았다. 개인특성 요인인 자아존중감, 공감능력 변수를 포함한 모형에서는 공감능력, 자아 존중감, 친구의 친사회적 행동, 그리고 친구의 반사회적 행동 순으로 청소년의 친사회적 행동에 통계적으로 유의미한 결과를 보였다. 따라서 또래영향모델과 개인특성모델이 모두 유효하나 개인특성의 영향이 더 큰 것으로 검증되었다. 또한 개인특성과 또래특성 간의 상호작용효과를 살펴본 결과, 자아존중감이 높은 경우 친구의 친사회적 행동이 본인의 친사회적 행동에 미치는 긍정적인 영향이 더 크고, 공감능력이 높은 경우 친구의 반사회적 행동이 본인의 친사회적 행동에 미치는 부정적인 영향이 더 적은 것으로 나타났다. 청소년의 친사회적 행동에 대한 또래집단의 영향력은 개인특성에 의해 영향을 받는 것으로 나타나, 또래영향모델과 개인특성모델은 청소년의 친사회적 행동에 상호보완적으로 작용하고 있는 것으로 검증되었다. 마지막으로 청소년의 긍정발달을 위한 사회복지적 함의를 논하였다.

This study investigates the effects of corrosion resistance characteristics of opponent materials in relative motion on the sliding wear behavior of mild carbon steel. Pin specimens made of mild carbon steel are tested at several sliding speeds against mating discs made of two types of alloyed steels, such as type D2 tool steel (STD11) and type 420 stainless steel (STS420J2), with different corrosion resistance characteristics in a pin-on-disc type sliding wear test machine. The results clearly show that the sliding wear behavior of mild carbon steel is influenced by the corrosion resistance characteristics of the mating disc materials at low sliding speeds. However, the sliding wear behavior at high sliding speeds is irrelevant to the characteristics because of the rising temperature. During the steady state wear period, the sliding wear rate of mild carbon steel against the type 420 stainless steel at a sliding speed of 0.5 m/s increases considerably unlike against the type D2 tool steel. This may be because the better corrosion resistance characteristics achieve a worse tribochemical reactivity. However, during the running-in wear period at low sliding speeds, the wear behavior of mild carbon steel is influenced by the microstructure after heat treatment of the mating disc materials rather than by their corrosion resistance characteristics.

This study explored the effects of self efficacy, classroom contextual characteristics and help-avoidance attitudes on academic help-seeking behavior. Participants were 210 4th grade students. Data were analyzed by Pearson's correlation coefficient and multiple regression analysis through the SPSSWIN 12.0. Results showed that students' self efficacy, perception of teacher behavior and goal orientations were positively related to help-seeking behaviors. Help-avoidance attitudes were negatively related to help-seeking behaviors. Cognitive efficacy and social-emotional efficacy facilitated help-seeking behaviors. Help-seeking behaviors were influenced by teacher's supportive help and expectation. Mastery goal orientations and performance-approach goal orientations promoted help-seeking behaviors but performance-avoidance goal orientations impeded help-seeking behaviors. Autonomous intention attitudes expedited help-seeking behaviors but intention based on ability diminished help-seeking behaviors.

The current-voltage characteristics of the semiconducting BaTiO3 ceramics are measured in the range of 0.01∼100 Volt. Non ohmic behavior was observed above Tc. This behavior is not dependent on specimen thickness and is not observed at the incomplete semiconducting sepcimen. From this experiment, non-ohmic behavior of PTC is attributed to Heywang's potential barrier not to space change limited current. In the low voltage range, current-voltage characteristics of PTC ceramics can be explained by Heywang model.

This study has examined multiple influences of several variables on parenting behavior by looking into illustrative studies. This study provides support to the view that various factors influence parenting and that parenting behavior is multiply determined. Characteristics of parents, children and the context in which parent-child relations occur cause different childrearing patterns among parents. This study can be summarized as follows: 1) Parental behavior is influenced to a large degree by what the parent brings to the situation. In other words, characteristics of the parent including personality characteristics, interpersonal skills, problem-solving skills, level of maturity, values and childrearing beliefs contribute to individual differences in parenting. 2) The parent's relationship history influences the personality characteristics that the parent brings to his or her adult roles. To understand who the parent is today, we have to look at who the parent was, and what the parent was doing in the years prior to parenthood. That is, we need to see the life course of the individual before parenthood. 3) Contextual variables including the immediate context and the larger context have proved to influence parental behaviors. Characteristics of the immediate context such as the quality of marital rationship can influence the parent's psychological well-being and his or her behavior toward the childen while characteristics of the larger context such as the economic situation and the neighborhood can influence the level of stress experienced by the parent and cosequently how the parent relates to his or her child. 4) In order to understand the development of the parent-child relationship we need to look at the characteristics of the child. Children may elicit positive behaviors from their parents, or they may possess characteristics that the parents find aversive thus leading to difficulties in the relationship. Therefore, much depends on the fit beween the characteristics of the parents and characteristics of the child. By examining multiple contemporaneous influences on parenting, this study could deepen the understanding of why parents have different childrearing patterns, why some parents fail to meet their children's demands and why parents act in certain ways. What we ultimately hope is that as we learn more about parenting and the development of parent-child relationships, we will be better able to provide parents with the supports they need to achieve their parenting goals.

The purpose of this paper is to analyze the difference of seafood dining consumer behavior by demographic characteristics (age, gender). This research surveyed 251 people in Busan, Korea. t-test, one-way ANOVA, and MDS were used to identify the difference of consumer behavior by demographics. The result of the research revealed the difference between demographic characteristics and seafood dining consumption. 20's showed to accept the trendy dining culture represented by salmon, sushi and shrimp, and 30's also have similar tendency. 40's have higher spending tendency to seafood dining like tuna restaurants. 50's and 60's showed conservative consumption propensity represented by grilled fish, braised fish and raw fish restaurants. In gender analysis, male have higher frequency than female about grilled eel. In the future, the seafood dining market would be reorganized with the expansion of sushi, salmon and shrimp dishes, which can be classified as a new dining market. In this research, we suggested fisheries supply and production strategies according to age and gender.

Historically, mothers have been noted as active health information seekers, reflecting their roles as health mangers and caregivers for their family members. However, previous studies have focused on health-related information behavior among mothers in native populations or mothers of children with specific diagnoses. To fill this research gap, this study focused on health information behavior among mothers of healthy infants and toddlers. Using Wilson's (1997) information-seeking model, this study aimed to uncover the relationships between mothers' demographic characteristics and their health information source use. Online surveys were completed by 851 mothers: 255 U.S.-born mothers, 296 Korean-born mothers, and 300 Korean immigrant mothers living in the United States. Results indicated that there were statistically significant relationships between mothers' nine demographic characteristics (mother's age, education level, household income, employment status, the number of children, years living in the U.S. (or Korea), fluency in speaking English, size of household, housing status) and their health information source use. Based on the results, the implications for information professionals at diverse organizations are discussed when they provide health information services to this specific population.
