본 연구는 총부양비를 최소화하는 적정인구성장률을 인구학적 부양비와 경제적 부양비로 나누어 계산하구 그것이 무엇을 의미하가를 연구하는 것이 목적이다. 이 연구를 위하여 연구모형을 제시하고, 합계출산율과 적정인구성장률의 관계를 명시하며, 그것이 궁극적으로 적정인구 규모에 어떤 의미를 갖는가를 탐색한다. 인구학적 부양비를 최소화하는 인구성장률은 $-0.03%{\sim}0.15%$의 범위에 있으며, 그것은 합계 출산율로는 $2.1{\sim}2.2$명에 해당한다. 경제적 부양비를 최소화하는 인구성장률은 유년층과 노년층의 상대적 개인 소비비중에 따라 인구성장률과 그것이 함의하는 합계출산율은 달라진다. 예컨대, $u_1:u_3=2:1$일 때 적정인구성장률은 $-1.17{\sim}-0.93%$, 그것이 함의하는 합계출산율은 $1.5{\sim}1.6$명이다. 한편 유년층 대비 노년층의 상대적 소비비중이 증가하는 경우에는 적정인구성장율이 높아져야 한다. 예컨대 $u_1:u_2=1:1.2$일 때 적정인구성장률은 $0.42{\sim}0.45%$이고, 그것이 함의하는 합계출산율은 $2.3{\sim}2.4$명이다. 본 연구에서 적정인구추계를 위한 기초 여론조사에 따라 진행된 상대적 소비비중을 계산한 결과에 따르면, 유년층과 노년층의 상대적 개인 소비비중은 $u_1:u_2=1.25:1$이며, 이에 따른 현재의 상황에서 한국의 적정출산율은 $1.9{\sim}2.0$명 수준으로, 이에 해당하는 적정인구성장률은 대략 약간의 네거티브 성장을 하는 경우라고 할 수 있을 것이다.

The purpose of this study was to inquiry implication of physical education based on the Zhaung Zi's philosophy. In order to investigate this purpose, I analyzed the text of Zhaung Zi. The result of the study was as followed. Zhaung-Zi oriented ideal image of human beings who has attained the stage of play(遊). He is an acquaintance (至仁), a man of god(神人), a true man(眞人). The purpose of physical education in Zhuang-Zi is paly(遊) which play well naturally. 'play is the gaming and play in which we can see the true face of the world and ourselves and can become on with the object in the world. Forget-enjoyment(至樂) of victory, records, and results are the purpose of physical education which can be found in Zhuang-Zi. The methods of physical education is the whole mind(專一), xixium(虛心), the feast of mind(心齋), forgetting everything(坐忘) etc. Physical education is to harmonious study with nature not artificially. The relation between teacher(coach) and student(player) is a relationship of mutual respect and consideration. The teacher(player) have to find the potential ability of student and he can help student realize potential ability of them.

When imaginary numbers were first encountered in the 16th century, mathematicians were able to calculate the imaginary numbers the same as they are today. However, it required 200 years to mathematically acknowledge the existence of imaginary numbers. The new mathematical situation that arose with a development in mathematics required a harmony of real numbers and imaginary numbers. As a result, the concept of complex number became clear. A history behind the development of complex numbers involved a process of determining a comprehensive perspective that ties real numbers and imaginary numbers in a single category, complex numbers. This came after a resolution of conflict between real numbers and imaginary numbers. This study identified the new perspective and way of mathematical thinking emerging from resolving the conflicts. Also educational implications of the analysis were discussed.

Directory searching and index searching methods are two main methods in web search engines. Both of the methods are applied to most of the well-known Internet search engines, which enable users to choose the other method if they are not satisfied with results shown by one method. That is, Index searching tends to come up with too many search results, while directory searching has a difficulty in selecting proper categories, frequently mislead to false ones. In this paper, we propose a novel method in which a category hierarchy is dynamically constructed. To do this, a category is regarded as a fuzzy set which includes keywords. Similarly extensible subcategories of a category can be found using fuzzy relational products. The merit of this method is to enhance the recall rate of directory search by expanding subcategories on the basis of similarity.

본 연구의 목적은 첫째 창업자가 창업을 함에 있어 창업준비를 통해 창업성과에 미치는 영향관계와 본질적으로 항상 내재되어 있는 실패에 대한 두려움 요인이 창업성과에 미치는 영향 관계를 실증 검증하고자 한다. 두 번째로 상반된 개념의 독립변수가 동시에 종속변수에 미치는 영향을 알아보고 이에 따라 변수간의 상관관계를 분석하고, 사회적지지를 조절변수로 하여 창업준비와 창업실패에 대한 부담감에 조절효과가 있는지 검증하고자 한다. 따라서 본 연구의 의의는 창업준비와 창업실패 부담감이 창업성과에 영향을 미치는 요인들에 규명하고 사회적지지의 조절효과 요인을 분석하는데 있다. 연구의 학문적 함의점은 주요 많은 국내문헌에서 창업실패감과 창업의지에 관한 연구중심에서 벗어나 창업준비와 실패에 대한 부담감이 창업성과에 미치는 영향을 직접적으로 검증하는데 있다. 또한 창업자들이 인식하고 있는 창업준비와 창업실패에 대한 부담감이 창업성과와의 영향관계를 파악하여 구체적인 실무적 시사점을 제공할 수 있다.

The purpose of this paper is to critically analyze the way of knowledge production in social welfare and to graft feminist epistemology to the discipline of social welfare. To put it more concretely, as analyzing the epistemological and methodological issues appeared in the articles in "orean Journal of Social Welfare", this study examines the meanings of feminist epistemology and its implications to research and practice in social welfare. From its onset, feminist research criticized the 'mainstream' ways of conceptualizing knowledge construction via research conducted upon a positivist epistemological position. Particularly, western feminists have problematized the androcentric bias embedded within the so-called 'social sciences' that we have taken for granted as 'scientific,' 'objective,' and 'neutral,' and attempted to redirect and reformulate the way of knowledge production with new concepts of 'strong objectivity,' 'partial/situated knowledge,' and 'strong reflection.' We believe that the implications of feminist epistemology to enable us to reflect the power relationship between subject and object, I and Other, and the researcher and the researched will contribute to recover the original vision of social welfare as critical theory and liberating practice in social work.

Previous studies indicate that depression is strongly correlated with suicide, suggesting that individuals with higher levels of depression are more likely to commit suicide. Statistical data, however, show that depression is more prevalent among females whereas suicidal incidents are much higher among males. Using the 1st Seoul Welfare Panel Data, this study aims to examine the association between depression and suicidal attitudes and further examine whether there is gender and age difference in the relationship. Sample consists of 7,396 individuals aged 18 and over. Research questions were answered through the structural equation modeling(SEM) and multi-group SEM. The results showed that (1) depression is significantly associated with suicidal attitudes, replicating the previous findings, (2) the association was much higher among males than females, suggesting that depressed males are more vulnerable to suicide than depressed females, and (3) the gender difference was primarily caused by the group of women aged 65 and over. Based on these findings, implications for theory and practice were discussed.

The purpose of this study is to find the implications of Christian education on the relationship between the formation of faith and digital literacy in the Korean society, which is rapidly changing within the fourth Industrial Revolution today through critical conversations on educational contexts. Over the past decade, Korean society has lived in an era of rapid and radical change more than any other time through a new way of life called the Fourth Industrial Revolution. The Korean church is also facing the reality that it must fulfill its urgent mission to deliver the unchanging truth in an ever-changing era. With this in mind, this study (1) identifies digital literacy as an essential competency requested in the era of the fourth industrial revolution by examining the relationship with congregation's life as well as its definition and contents, (2) discovers educational rationale for the relationship between faith formation and digital literacy by applying educational context of Christian education with attention to the educational efficiency of digital literacy, and (3) finds educational implications of digital literacy by re-conceptualizing the contents, context, role of teachers and students, and evaluation in the context of Christian education. I hope that this study will help Christian education serve for the spread of the Gospel of Christ and the realization of the kingdom of God on this earth through digital media in the future more time-responsively and mission-practically.
