본 연구는 서울 지역 초 중 고등학생들을 대상으로 사교육이 학생의 인지 역량(국어, 수학, 영어 학업성취도)과 비인지 역량(교우관계, 자존감, 창의적 성격, 목표의식)에 미치는 영향을 자기주도 학습과 비교하는 방식으로 평가하였다. 분석 결과, 사교육은 학생의 인지 역량 발달에 어느 정도 효과가 있었으나 학교 급이 올라가면서 그 효과가 하락하였고, 비인지 역량 측면에서는 아무런 효과가 없었다. 반면, 자기주도 학습은 학생의 인지 비인지 역량 발달에 긍정적인 영향을 끼치는 것으로 나타났다.

The goal of this study was to explore the use of multiple SNS platforms and determine whether the number of used platforms affects one's online self-presentations across the said platforms and if there is any difference in one's online and offline self-presentations based on how many SNS platforms are used. This work studied online self-presentations, compared the on/offline ones and tried to find out if the inconsistencies of one's own (observer's) self-presentations both online (across platforms) and on/offline affected the observer's impression formation (likability, trustworthiness and hypocrisy) of others. The study also aimed to find out if the impression of the others' inconsistency both online and offline would differ based on the level of intimacy between the observer and the discussant. Three levels of intimacy were studied in order to do this: friends, acquaintances and strangers (online-only friends). The results showed that the more platforms people used the more inconsistent their online self-presentations got. Even though the results of the study showed barely significant relationship between the number of SNS accounts and one's online and offline self-presentation, and partial connection between observer's inconsistent self-presentations and impression formation of others, interestingly enough, the results managed to find significant differences between the impressions based on the level of intimacy between the observer and the discussants.

본 연구는 독서요법이 대학생들의 자아형성과정에서 겪는 스트레스에 미치는 효과를 알아보기 위하여 시도하였다. 실제로 S대학 도서관에서 8주 동안 독서요법을 실시하여 대학생들의 자아형성과정에서 겪는 스트레스를 파악하여 독서요법 실시 전후의 스트레스 차이를 비교하기 위해서 짝비교 t 검증(paired t-test)을 실시하였다. 그 결과 독서요법이 자아형성과정에서 겪는 스트레스를 줄이는데 유의한 효과가 있는 것으로 나타났다. 그러므로 대학도서관에서도 독서요법에 대하여 적극적인 홍보와 다양한 프로그램 개발이 필요하다.

The self-assembled formation of octadecanethiol (CH3(CH2)17SH) on a gold substrate was studied using a quartz crystal microbalance (QCM) and a scanning tunneling microscope (STM). From the QCM measurements at vario us concentrations of octadecanethiol solutions in hexane and alcohol, the adsorption process of octadecanethiol onto Au was confirmed to consist of two steps as follows: (i) fast but disordered adsorption and (ii) a thermodynamically controlled rearrangement for uniform packing of octadecanethiol. Also, it was revealed that the adsorption rate became faster in ethanol than in hexane since less solubility of octadecanethiol in ethanol could help the formation of the monolayers. At 5 ${\times}$10-7 M solution, the monolayer formation was monitored by STM. The morphology of monolayer region was initially circular (diameter size: 7.26 $\pm$ 2.1 nm) and gradually changed to a stripe type after several minutes. At higher concentration, the self-assembled monolayer was formed immediately after the solution was introduced to a substrate.

The role of consumer self-confidence is important in consumer's purchase decision. Nevertheless, the use of self-esteem measures might cause misinformation in the specific situation of the marketing-related point of view. In this study, consumer self-confidence was measured by marketing oriented tools to clarify the dimensions of consumer self-confidence while the influence of consumer self-confidence on clothing satisfaction was also investigated. A total of 325 questionnaires were collected by surveying university students in Seoul and the surrounding metropolitan area using convenient sampling. The data were analysed by factor analysis, ANOVA, t-test, and regression by using SPSSWIN program. The findings of the study were as fellows. First, the consumer self-confidence was composed of 6 sub-scales: information acquisition, personal outcomes decision making, social outcomes decision making, consideration-set formation, persuasion knowledge, and marketplace interfaces. Second, female subjects rated higher on consumer self-confidence than male subjects did in social outcomes decision making and consideration-set formation. Third, higher income was correlated with higher social outcomes decision making and consideration-set formation. Finally, clothing satisfaction was influenced by personal outcomes decision making and information acquisition.

A control system design based on coupled nonlinear oscillators (CNOs) for a self-organized swarm system is presented. In this scheme, agents self-organize to flock and arrange group formations through attractive and repulsive forces among themselves using CNOs. Virtual agents are also used to create richer group formation patterns. The objective of the swarm control in this paper is to follow a moving target with a final group formation in the shortest possible time despite some obstacles. The simulation results have shown that the proposed scheme can effectively construct a self-organized multi-agent swarm system capable of group formation and group immigration despite the emergence of obstacles.

In this study the formation mechanism of AlN synthesized by SHS(Self-propagating high-temperature Syn-thesis) was studied in order to obtain uniform AlN powder size and morphology. Based on the morphology of AlN synthesized and the calculation of the temperature of Al powder as a function AlN layer thickness the formation mechanism of AlN was proposed.

This paper presents a self-organizing scheme for multi-agent swarm systems based on coupled nonlinear oscillators (CNOs). In this scheme, unicycle robots self-organize to flock and arrange group formation through attractive and repulsive forces among themselves. The main result is the maintenance of flexible and scalable formation. It is also shown how localized distributed controls are utilized throughout group behaviors such as formation and migration. In the paper, the proposed formation ensures safe separation and good cohesion performance among the robots. Several examples show that the proposed method for group formation performs the group behaviors such as reference path following, obstacle avoidance and flocking, and the formation characteristics such as flexibility and scalability, effectively.

This study investigates the influence of self-efficacy in purchasing clothes in the consumer satisfaction formation process. A survey was conducted on 300 adults living in the Seoul and Gyeonggi area and 231 completed questionnaires were used for analysis. The survey questionnaires measured the respondent's self-efficacy in purchasing clothes, expectation, perceived performance, expectation confirmation, and satisfaction level. The data were analyzed by moderated regression analysis. The results are as follows. First, for apparel products, perceived performance, and expectation confirmation have a direct effect on consumer satisfaction, while expectation has no direct effect on consumer satisfaction. This finding agrees with the results reported in a previous study on consumer goods with low ambiguity in assessing products and services including sneakers, underwear, cereals, and financial services. Second, the lower the self-efficacy in purchasing clothes, then the increased effect of the expectation confirmation that influences consumer satisfaction. However, the self-efficacy in purchasing clothes did not show any moderating effect on the perceived performance affecting the consumer satisfaction. The self-efficacy in purchasing clothes seems to have a moderating effect on the consumer satisfaction formation process by affecting the ambiguity in pre-purchase product assessment and not in post-purchase product evaluation.

본 연구는 커피전문점 이용자의 기능적 일치성과 자아일치성이 긍정적 감정과 부정적 감정에 어떠한 영향을 미치는지를 실증적으로 규명하고, 이러한 이차원적인 감정 구조가 커피전문점에 대한 태도형성에 미치는 영향을 확인하고자 수행되었다. 서울지역 대학생을 대상으로 총 280부의 자료를 실증분석에 사용하였으며 가설검증을 위해 구조방정식 모형을 이용하였다. 결과를 살펴보면 기능적 일치성은 커피전문점 이용객의 긍정적 감정에 정(+)의 영향을 미치며 부정적 감정에 부(-)의 영향을 미치는 것으로 나타났다. 반면 자아일치성은 커피전문점 이용객의 긍정적 감정에(+)의 영향을 미치는 것으로 밝혀졌다. 마지막으로 커피전문점 이용객의 긍정적 감정은 태도에 정(+)의 영향을 미치고 부정적 감정은 태도에 부(-)의 영향을 미친다는 것이 나타났다. 이 같은 결과는 커피전문점 이용자의 기능적 일치성과 자아일치성이 긍정적 감정과 부정적 감정을 매개로 하여 점포태도형성에 영향을 주는 것을 의미한다.
