This article focuses on a transaction log analysis of the DISCOVER online catalog user interface at Duksung Women's University Library. The results show that the most preferred access point is the title field with rate of 59.2%. The least used access point is the author field with rate of 11.6%. Keyword searching covers only about 16% of all access points used. General failure rate of searching is 13.9% with the highest failure rate of 19.8% in the subject field and the lowest failure rate of 10.9% in author field.

This research focuses on how users behave when they search by subject using online public access catalog(OPAC). Major findings are as follows. 1)Main access poults are subject field$(55.2\%)$and title field$(42.2\%)$. 2) The search failure rate in subject searching is $59.3\%$. 3) Ma]or reasons for subject search failures are two-fold : use of inappropriate search terms $(48.5\%)$ and non-use of Boolean Operators$(42.5\%)$. 4) In order to overcome search failures users tend to change originally used search terms$(42.0\%)$ and search fields$(33.8\%) into different ones.

우리나라의 자영업자 비율은 G7보다 높은 수치로서 OECD회원국들 중 상위에 속하며, 그 중에서도 소상공인은 전체 사업자 수의 93.3%에 달한다. 하지만 2020년 3/4분기 기준 서울시의 소상공인 5년 생존율은 38.4%에 불과하며, 대표적인 폐업/업종전환 고려 이유는 수익성 악화, 판매부진, 경기불황이다. 이처럼 폐업한 소상공인들은 취업을 하거나 기존 업종으로 다시 창업을 하는 경우도 있으나, 새로운 업종에 도전하기도 한다. 그러나 재창업의지에 대한 선행연구는 많은 반면, 업종전환 및 업종전환 의지는 아직 심도있게 연구된 바 없다. 본 연구의 목적은 사업에 실패한 뒤 재창업을 하였거나, 사업에 실패한 뒤 재창업을 목표하는 소상공인을 대상으로 창업 실패 경험이 업종전환 의지에 미치는 영향 관계를 검증하는 것이다. 따라서, 본 연구에서는 소상공인의 사업 실패 경험이 업종전환 의지에 미치는 영향의 탐색적 연구를 사회적지지 조절효과를 중심으로 진행하였으며, 소상공인의 사업 실패 경험이 업종전환 의지를 높인다는 인과관계를 검증하고자 한다.

The unicasting routing technology of VANET is very important for user convenience. Unicasting packets must be forwarded to the appropriate path in order to arrive to the destination. However, there are so many problems because the vehicle nodes have limited information related to the routing decision. In particular, packet delivery failure will be occurred by selecting the path already failed again. We call this problem as 'Failed Path Re-Selection Problem'. In this paper, we propose an enhanced rerouting function of VANET Routing. The proposed rerouting function uses the failed path information when rerouting function executed. For this rerouting function, failed path information will be stored in the packet whenever the routing fail occurred. By the comparison with the performance of legacy VANET routing function, the superiority of the proposed method can be seen.

This study examined the impact of failure tolerance on exploration and exploitation activities and the impact of these activities on management performance in the representatives of re-start-up companies. Recently, policy and social support for re-starting businesses has been increasing. This study seeks to verify whether the psychological factors of the re-founder are related to management performance. Therefore, a research model that combines failure tolerance, which is a psychological and pedagogical variable, and management performance, which is a management variable, was presented and empirical analysis was made. The research targets were conducted on re-founders who received funding from Korea SMEs & Startups Agency. The analysis of the psychological characteristics of the re-start-up, failure tolerance and the effect on the exploration and exploitation activity, all showed positive effects, and the analysis of the effect of the exploration and exploitation activity on the management performance, showed that the exploration activity did not affect, and the exploitation activity had a positive effect. This study is intended to provide theoretical and practical implications.

This study explored the influence of failure experience of Korean pharmaceutical industries on the innovative activities of corporations from the perspectives of R&D and knowledge search. Previous studies have defined the cause of the failure or studied the reasons for the decline. However, studies analyzing the influence of failure on the innovative activities of corporations are rare. This study set a research period of 10 years for the Korean pharmaceutical industry to conduct a longitudinal analysis of the influence of the influence of failure on innovation activities and the influence of innovation activities on radical innovation. A summary of the research results is as follows. Firstly, failure of corporations induce exploratory innovation activities, and the extent differs greatly from the size of financial slack resource. Secondly, experiences of corporations' failure were not significant from the perspective of knowledge search. Thirdly, the interaction between the corporation's exploratory innovation activities and knowledge search had a positive (+) relationship with radical innovation performance. This study is significant in that it suggested empirical evidence by verifying the positive influence of failure to learning and innovation unlike previous researches viewing failure negatively, and suggested the direction of future studies based on these research results.

계속 높아지는 기업가정신과 창업의도에도 불구하고 2017년 OECD 보고서에 따르면 한국은 실패에 대한 두려움이 높은 국가로 전체 7위롤 기록했다. 실패 후 신용 불량으로 인한 재기 불가능에 대한 인식이 여전히 팽배해 창업을 저해하는 요인으로 아직까지 큰 비중을 차지하고 있다. 그러므로 실패에 대해 관용적인 문화와 실패를 통한 학습 독려, 실패 기업인의 재도전 지원 활성화 정책은 한국을 진정한 창업국가로 변모하게 할 것이다. 그러나 무엇보다 실패를 경험한 창업가 본인 자신이 새롭게 재기에 임하는 마음가짐이 중요하므로 본 연구의 목적 역시 재창업자가 다시 창업에 어떤 자세로 임해야 하는지 찾고자 하는데 있다. 따라서 본 연구는 재기에 성공한 4명의 사업가와 재도전을 했으나 여전히 성과를 못 내고 있는 5명의 사업가를 인터뷰하여 재도전의 성공 요인을 탐색하고자 한다. 연구 결과, 재기 창업가가 재도전 성공을 위해 가져야 할 자세와 역량을 1) 지식(knowledge), 2) 인지(cognition), 3) 감정(emotion) 이상 3가지 관점에서 기존의 연구가 다루지 못한 접근법을 제안한다. 먼저, 지식 관점에서 보면 기존 사업과의 동질성 여부가 중요한 것이 아니라, 새롭게 진출하는 영역에 대한 준비성이 재도전의 성공 여부에 영향을 미쳤다. 다음으로, 인지적 관점에서는 과거 실패의 원인에 대한 분석과 자기 실책으로의 귀인은 차이를 보이지 않았고 오히려 앞으로 영위할 사업에 대한 여러 사람들의 지적과 충고에 대한 수용 역량(coachability)이 성공과 실패를 나눴다. 마지막으로 감정 관점에서 선행연구는 실패로부터 슬픔을 빨리 극복하는 사람이 학습과정도 빨리 이뤄지는 것으로 여겨졌으나, 슬픔의 극복은 재기 후 성과와는 관련이 없었으며, 본 연구에서는 재기 전 생계유지가 가능한 상태 여부가 성공의 선행조건이 될 수 있음을 발견하였다.

최근 모바일 컴퓨팅 기술이 급격이 발전하면서, 이동 애드-혹 네트워크(Mobile Ad-Hoc Network, MANET)에 대한 연구가 활발히 진행되고 있다. 그러나 대다수의 MANET에 관한 연구는 하나의 MANET 내에서 이루어지는 라우팅 방법이나 에너지 관리에 대한 것으로 MANET 내에서 검색에 실패 했을 경우에 대한 해결 방법은 없는 상태이다. 본 논문에서는 하나의 MANET에서 검색에 실패한 경우에 기반망인 무선 AP를 이용하여 또 다른 MANET으로 연결하고 정보를 검색 할 수 있도록 탐색범위 확장을 위한 방법을 제안한다. 본 논문에서 제안한 방법은 보다 넓은 범위에서 필요로 하는 정보를 가진 단말을 탐색할 수 있게 함으로써 MANET에서의 검색 성공률을 높일 수 있다.

The studies on the shortest path algorithms based on Dijkstra algorithm has been done continuously to decrease the time for searching. $A^*$ algorithm is the most represented one. Although fast searching speed is the major point of $A^*$ algorithm, there are high rates of failing in search of the shortest path, because of complex and irregular networks. The failure of the search means that it either did not find the target node, or found the shortest path, witch is not true. This study proposed $A^*$ algorithm applying method that can reduce searching failure rates, preferentially organizing the relations between the starting node and the targeting node, and appling it in reverse according to the organized path. This proposed method may not build exactly the shortest path, but the entire failure in search of th path would not occur. Following the developed algorithm tested in a real complex networks, it revealed that this algorithm increases the amount of time than the usual $A^*$ algorithm, but the accuracy rates of the shortest paths built is very high.

The present study focused on frustration emotion investigated the variables evoking frustration and the process in which sense of frustration would be overcome, and explored the principle of aesthetics the consumers under the frustration might prefer in choosing goods. The results of this study are as follows. First, consumers usually felt frustration rather than anger when it became obvious that their objectives could not be met and that they failed to achieve their objectives due to uncontrollable cause. Second, consumers who felt frustration wanted to receive emotional support and comfort from close acquaintances rather than to cope actively with the unsuccessful situation by renewed challenges. Third, consumers, once frustrated, preferred harmony principle rather than emphasis principle in terms of esthetics in choosing design of goods. Therefore, marketing managers are advised to approach to the consumers who felt frustration on the basis of harmony principle in design of goods.
