This study examines the structural relationships between service quality, satisfaction, and behavioral intentions in responsible tourism. In particular, the study focuses on moderating effects of age. Data were collected from 471 tourists from seven responsible tourism agencies. SPSS 20.0 and AMOS 18.0 were used for frequency, reliability, exploratory factor, confirmatory factor, and path analyses. The results of a exploratory factor analysis yield two dimensions of service quality (functional quality and technical quality). The results of structural equation modeling indicate that functional quality and technical quality had positive effects on satisfaction, which in turn had a positive effect on behavioral intentions. In addition, age moderated the relationships between service quality, satisfaction, and behavioral intentions such that functional quality had a positive effect on satisfaction in the group of tourists in their twenties and thirties and that functional quality and technical quality were important factors for tourists in their forties. The results are expected to help responsible tourism communities better manage service quality to increase tourist satisfaction.

The purpose of this study was to analyse 3, 4, 5-year-old children's private speech according to their age and task characteristics (structured task vs. unstructured task). In order to achieve the goal, the main effect of age, characteristic of tasks and interaction effect were considered among age and characteristic of tasks on preschool children's private speech. The subjects were each 30 3, 4, 5-year-olds from preschool in Busan, South Korea. The structured task was puzzle task and the unstructured task was drawing task from TCT-DP. The data was analyzed by repeated measurement two way ANOVA: 3(age) ${\times}$ 2((characteristic of task). As a result, firstly, total private speech of 4-year-old was higher than 3-year-old, 5-year-old in both tasks, and total private speech of 5-year-old was higher than 3-year-old in both tasks. Secondly, the task-irrelevant private speech was not affected by main effect of age and characteristic of task and interaction effect between age and characteristic of task. Thirdly, the task-relevant private speech was received both main effects and interaction effects between age and characteristic of task. Finally, the external manifestation of inner speech were not received effect of age but received effect of characteristic of task, and received interaction effect between age and characteristic of task. The results of this study imply that characteristic of task is an important factor inducing children's private speech.

Purpose: Bone marrow has long been a source of primary cells. This study was performed to evaluate the effects of age and sex on the cellular viability and expression of stem cell markers of mRNA and on the protein expression of bone marrow stem cells (BMSCs) derived from healthy donors. Materials and Methods: Stem cells were isolated from human bone marrow and plated in culture plates. The shape of the BMSCs was observed under inverted microscope. Quantitative cellular viability was evaluated using a Cell-Counting Kit-8 assay. The expression of stem cell surface markers was tested and a series of quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot was performed to evaluate the expression in each group. Result: The shapes of the cells at 20s, 30s, and 50s were similar to each other. No significant changes in cellular viability were noted among different age groups or sex groups. The BMSCs expressed CD44, CD73, and CD90 surface markers but did not express CD14 and CD34. There were no noticeable differences in CD surface markers among the different age groups. The expressions of CD surface markers were similar between men and women. No significant differences in the secretion of vascular endothelial growth factors (VEGFs) were noted at Day 3 between different age groups. qRT-PCR regarding the expression showed differences between the age groups. However, Western blot analysis showed a decrease in expression but did not reach statistical significance (P>0.05). Conclusion: This study clearly showed no significant differences in shape, cell viability, expression of stem cell surface markers, or secretion of human VEGF among different age groups. However, western blot analysis showed a tendency of age-related decrease which did not reach statistical significance. Collectively, autologous or allogeneic BMSCs should be meticulously applied to obtain optimal results regarding age and sex.

본 연구에서는 인지노화와 그에 영향을 미치는 사회심리학적 요인에 대해 개관하였다. 노화로 인한 인지기능의 변화는 세부 기능별로 상이함에도 인지노화는 쇠퇴의 관점으로 주로 해석되고 있다. 인지노화에 대한 부정적인 시각은 노화 고정관념(age stereotype)과 같은 사회심리학적 요인이 반영된 결과로 볼 수 있다. 노화 고정관념은 문화권에 따른 차이는 있으나 보통 부정적인 측면이 강하게 나타나는데, 더 부정적인 고정관념을 보일수록 기억 수행이 저하되는 것으로 나타났다. 노화 고정관념을 실험적으로 활성화시키는 경우, 긍정적인 고정관념을 제시받은 노인이 부정적인 고정관념을 제시받은 노인에 비해 더 높은 기억 수행을 보였다. 자신의 인지기능에 대한 평가인 자기신념(self-referent belief)도 인지기능에 영향을 미치는 것으로 나타난다. 보통 노인의 자기신념이 청년의 자기신념보다 낮게 나타나고, 자기기억신념의 수준은 실제 기억 수행과 관련되는 것으로 나타난다. 이상의 사회심리학적 요인이 인지기능에 미치는 영향에 대한 이론적 설명과 시사점이 논의되었다.

우리나라 노동시장은 자영업의 비중이 크고 연령집단에 따라 자영업 비중의 차이가 크지만, 경기변동이 자영업 이행에 미치는 영향의 연령집단별 차이에 대한 연구는 미흡하다. 이에 본 연구는 한국노동패널 5~11차 자료를 활용하여 구축가설과 유인가설을 중심으로 분석하였다. 분석결과, 실업률이 높을수록 자영업 이행률이 높아져 구축가설을 지지한다. 기업가 정신의 발현보다는 노동시장여건의 악화로 자영업으로 밀려난 것으로 볼 수 있다. 연령집단별로 보면, 청년층에 비해 30대와 40대의 자영업 이행률이 높다. 경제활동이 왕성한 30~40대가 주변부 노동시장에 진입할 확률이 높아서, 자영업이 특정 연령계층의 문제가 아님을 알 수 있다. 또한 40대의 자영업 이행은 직업기회가 제한될 때 급증하여, 경기불황에 자영업으로 밀려가는 것으로 나타났다. 40대의 고용이 경기변동에 취약한 것을 말해준다.

When age-role i-: being confused and fasion is as whimsical as these days, the norm on the length of the skirt can be a matter of controversy. This study aimed to see if there exists decisive norm on skirt lengths according to the age of feminine stimuli and the sex and age of perceiver. It also aimed to find out whether the norm of the individual perceiver is influenced by the assumed norm of generalized others. Questionnaire including linedrawings of feminine lower body was given out to be marked with age-proper length of skirt. Results revealed existence of certain length norms according to the age of the stimuli. Norms also varied according to the age of the perceiver and interaction effects among the age, sex of the perceiver and the age of the stimuli existed. Assumed norms of the generalized others were different from the actual norms of the individual. Interaction between the ages of the stimuli and perceiver affected the difference between the actural individual norm and the assumed norm of the generalized others.

젖소의 선형심사형질은 젖소의 생물학적 변이를 심사자의 직관에 의하여 변이의 정도에 따라 점수를 부여한다. 심사형질에 대한 정의에 의하여 연령과 비유기에 상관없이 변이의 정도를 수치화 하기 때문에 형질에 따라서 필연적으로 연령과 비유기의 영향을 받을 수밖에 없다. 본 연구에서는 연령과 비유기가 선형심사형질에 미치는 영향을 조사하고 그를 보정하기 위한 보정계수를 추정하였다. 키 강건성, 체심, 엉덩이 너비, 뒷다리 옆모양과 앞유방 부착이 연령에 따라 증가 또는 감소하는 경향을 보이면서 크게 영향 받는 것으로 조사되었으며, 유용성, 뒷유방 높이, 뒷유방 너비와 정중제인대는 비유기에 따라 영향을 받았다. 유방깊이는 연령과 비유기 두 가지 요인 모두로부터 영향을 받았다. 추정된 보정 계수에 의한 각각의 보정계수를 적용한 결과 연령과 비유기에 영향 받는 모든 형질에서 분만년월, 심사자 등의 변이에는 작은 영향을 미치며, 보정하고자 하는 요인의 변이를 크게 줄여 보정효과가 양호한 것으로 나타났다. 유방깊이는 연령과 비유기에 대한 보정계수를 동시에 적용한 결과 두 요인 모두에서 변이를 크게 줄였다.
