In this study of the relationships between quality of children's friendships, their self-perception and school adjustment, 434 4th, 5th, and 6th graders replied to a series of questionnaires. Girls reported higher levels of quality of friendship in the areas of emotional security, help, intimacy, and acknowledgement than boys. Boys showed higher levels of self-perception in cognitive competence, athletic ability and social acceptance than girls. Positive friendship quality and friendship satisfaction were related to self-perception and school adjustment. Variables that influenced school adjustment were social behavior, cognitive competence, global self-worth, pleasure in companionship, and athletic ability. For boys, variables which influenced school adjustment were social behavior, cognitive competence, pleasure in companionship, and global self-worth. For girls, the variables were global self-worth, cognitive competence, trust, social behavior, and athletic ability.

This study analyzed the changes in household consumption expenditure of retired households using Korean panel data. We compared the pre and post retirement-consumption levels in different consumption categories using panel data. Paired t-test showed that changes in the consumption patterns before and after retirement were not significant except for the households in the third net worth quartile. Analyzing the effect of retirement on the level of household consumption expenditure, this study found that the effect of retirement was not significant in overall, although retirement had a negative effect on the level of consumption expenditure among households in the lowest net worth distribution. Understanding changes in consumption patterns of retiring households provides important information to design social security policies.

In this study, we compared how different the self-perception and the daily hassels between the Korean and American children. The subjects were 706 fifth and seventh grade students. Data were obtained by administrating a questionnaire. The instruments used for this study were self-perception profile for children scale(SPPC) and stress scale. 1. All the SPPC factors for Korean children was significantly lower than those for American children. The SPPC fators for American children didn't show any significant differences by grades. But for Korean children seventh graders showed significantly lower SPPC than fifth graders. 2. The most significant factor to predict the golbal self-worth was physical appearance for boys and girls. Self perception for physical appearance is more influential factor than scholastic competence to form the positive self-perception for both boys and girls. 3. The daily hassels for Korean children were significantly higher than those for American childredn. Also daily hassels for seventh graders were significantly higher than those for fifth graders. 4. Daily hassels global self worth correlated negatively. When the level of stress was increased, the global self-worth was decreased.

This study of the characteristics and the relationships of children's emotional intelligence (EQ) and self-esteem had a sample of 1060 5th grade children. The rank order of four EQ factors from highest to lowest was "perception of emotion", "other-regulation and self-expression", "self-regulation and emotion utilization", and "empathy". Among self-esteem factors, "general self-worth" had the highest correlation with overall self-esteem; "physical appearance" was most strongly correlated with "general self-worth". Relationships between EQ and self-esteem showed that higher EQ was associated with higher self-esteem. Among EQ factors, "other-regulation and self-expression" was the strongest predictor of "behavioral conduct." The next strongest predictor of self-esteem among EQ factors was "self-regulation and utilization of emotion". Other self-esteem factors well predicted by EQ were "general self-worth", and "scholastic competence".

The assumption of reinvestment rate leads to the results conflicting with the priority order of investments determined by net present worth. It has been revealed through various studies that the priority order of projects determined by the criteria based on internal rate of return is different from that determined by present worth. This study is to find out how to define reinvestment rate of return influencing the decision-making of the priority order through examining the meanings of reinvestment rate of capital and true rate of return, and to present some examples with a simple mathematical model.

This Paper represents time-dependent stochastic variations of common discounted cash flow formulae with explicit consideration given to inflation. The cash flow, the ratio of discounting or compounding, and the rate of inflation are allowed to vary with time in a random fashion in equations for the compound amount of a single payment, present worth of a single payment, amount of an annuity, periodic deposits to accumulate a future amounts, present worth of an annuity and capital recovery And all formulae are derived for the case of discrete random variations.

This paper describes to determine optimum main particulars of warships which satisfy user's requirements in a concept design stage with minimum construction cost and maximum transportation efficiency. Present worth was used as an assessment criteria of the economical efficiency. And Pareto optimal set was used to have the optimum design.

'2013년 산업연관표'를 활용하여 철도운송서비스산업의 위상과 국가 경제에 미치는 효과를 분석하였다. 이를 '2003년 산업연관표'를 이용한 분석결과와 직접 비교함으로써 지난 10년 동안의 변화를 살펴보았다. 지난 10년간 우리나라의 철도운송서비스 산업은 생산액, 부가가치, 수출입 등에서 많은 변화가 있었다. 이를 가장 선명하게 보여주는 지표는 생산, 부가가치, 수입유발 승수의 크기이다. 2013년에 철도여객서비스의 생산, 부가가치, 수입유발 승수는 2003년에 비해서 각각 2.1배, 0.03배, 1.29배 증가하였다. 그리고 철도화물서비스는 각각 1.17배, 0.02배, 0.64배씩 증가하였다. 이 수치들을 통해서 지난 10년 동안에 철도운송서비스산업과 다른 산업들 간의 투입산출구조가 상당히 많은 변화를 거쳤음을 알 수 있다. 그리고 산업연관분석 연구에는 무엇보다도 최신의 자료를 이용해야 더 시의적절한 결과를 도출 할 수 있음도 새삼 확인되었다.

만화가 예술장르의 하나로써 회자되는 것을 발견하기란 어렵지 않다. 그런데도 여전히 예술 전반에 관한 논의에서 만화는 제외되는 일이 흔한 것은, 만화의 예술적 가치를 규명하고 알리기 위한 노력이 그 효과를 보이지 못하고 있기 때문인 듯싶다. 어떤 예술장르의 가치를 밝혀내어 알리고 그 위상을 굳건히 다지게끔 하는 일은 비평의 몫이다[l]. 그러나 만화비평은 그와 같은 기능을 위한 뚜렷한 준거가 마련되지 않은 바, 그러므로 본고에서는 만화비평이 만화의 예술적 가치를 판단하고 제시하기 위해 어떠한 준거를 가져야 하는지를 논하고자 한다. 이를 위해 모든 예술의 보편 타당한 가치를 밝히고자 시도했던 예술이론들을 대상으로 논의를 진행하여 각 예술이론들로부터 도출 가능한 준거들을 살펴보고, 그들이 만화에 대해 구체적으로 제시할 수 있는 준거에 대해 살펴본다.
