This study examine the relation between additional disclosure information of external audits details on consolidated financial statements, audit hours, and audit fees. The results of the analysis of listed companies that disclosed consolidated financial statements from 2014 to 2016 are as follows. First, the additional disclosures of the consolidated financial statements external audit is positively associated with the audit hours of the auditor. This result can be interpreted that the additional disclosure of the consolidated audit information is based on the incentive to provide useful information of auditor. Second, the audit fees of the auditors for additional disclosures in the consolidated financial statements were not significantly related. This suggests that, the additional disclosure of the consolidated audit practice is not based on the auditor's perception of the audit risk. This study provides that information on the external audit details of audit reports and consolidated audit reports is distinguished and disclosed, providing useful information to researchers. In addition, this study suggests policy implications by demonstrating that disclosure of the details of the external audit of the consolidated financial statements is based on the auditors' incentive to provide useful information.

최근의 하천복원 사업은 제외지 중심의 하천복원에서 벗어나 제내지의 격리 차단된 구하도까지 복원하고자 하는 노력이 시도되고 있다. 그러나 하천복원에 따른 수리적 및 생태적 연결성 향상이 적절히 수행되는지에 대한 정량적 평가 수단이 부족한 상태다. 본 연구에서는 구하도 복원에 따른 생태적 연결성 평가수단으로서 복원전 후 수리해석 결과를 이용하여 대상어종의 서식처적합도지수(HSI)와 식생의 공간분포를 분석 또는 예측할 수 있는 모형을 개발하였다. 공간분포된 수리특성을 위해서는 2 3차원의 모형이 필요하지만 복잡한 계산과정, 고도의 기술 및 많은 시간과 비용이 필요하다는 점에서 접근이 용이하지 않다. 이에 1차원 홍수추적모형의 결과를 이용하여 1차원 수리특성을 2차원으로 확장시키는 수치모형도 함께 개발하였다. 다만 개발된 각 모형의 단계별 실행 결과는 개별적인 요소의 평가로서 그 의미가 작으므로 하천복원의 종합적 평가를 위한 수리-물리서식처-식생의 통합적 모의가 필요하다 개발된 모형의 사용성 증대 및 생태적 연결성 평가 통합모형으로의 발전을 위해 개발된 모형을 하나의 연동시스템으로 구축하고자 하며, 연동 시스템을 이용하여 수리적 및 생태적 연결성을 신속하고 간단하게 해석할 수 있다.

본 논문에서는 숫자음과 단위음으로 구성된 한국어 연결 단위숫자음 인식의 성능 향상을 위하여 한국어 연결 단위숫자음의 특징을 분석하였다. 한국어의 단위숫자음은 숫자음 한음절과 단위음 한음절로 구성된 두음절의 연속적이고 반복적인 발성으로 나타난다. 숫자음에서의 인식 대상 어휘는 숫자음이라는 제한된 규칙을 갖는 가변 숫자음이다. 따라서 개수, 금액, 단위량, 거래량 등에서 나타날 수 있는 가변 숫자음을 인식하기 위하여 FSN(Finite State Network)을 구성하였다. 음향 모델은 한국어 숫자음과 같이 발성구간이 짧은 어휘의 연결음 (connected word)의 인식에서 효과적인 반음절쌍(demi-syllable pair) 모델을 이용하였다 실험결과, 화자 독립적인 가변 숫자음 60문장의 테스트 데이터에 대해서 문장 인식률 91.0%로 인식 성능을 향상시킬 수 있었다.

애드 혹 유비쿼터스 컴퓨팅 환경의 가장 큰 특징은 연결의 역동성이다. 노드의 이동으로 인하여 두 노드를 연결하기 위한 경로를 지속적으로 재발견하여야 한다. 한편, 응용 계층에서도 사용자에게 현재의 상황에서 가장 적절한 서비스를 제공하기 위하여 연결된 서비스를 동적으로 재발견/재구성하게 된다. 이러한 환경에서는 이러한 재발견의 부담을 줄이는 것이 중요하다. 발견을 위한 비용이 응용 계층과 네트워크 계층에서 이중으로 발생하는 것을 회피하기 위하여 본 연구에서는 응용 계층의 레이블을 네트워크 계층에서 라우팅의 대상으로 사용하도록 제안한다. 물론 IP 주소에 기반한 라우팅도 동시에 지원한다. 본 연구에서는 IP 주소는 물론이고 응용 계층 레이블을 수용할 수 있는 공유된 라우팅 기법으로서 SGR(shared generic routing)을 제안한다. 시뮬레이션을 통하여 SGR이 발견의 비용을 효과적으로 줄 수 있음을 보였고 리눅스 운영 체제 환경에서 구현하여 실제 적용 가능성을 제시하였다.

본 연구에서는 한글 문자 인식을 수행하였다. 한글 인식을 수행하되 고딕 인쇄체 문자를 대상으로 하였고, 자소 단위 인식을 통한 인식을 수행하되 기존 한글 문자 인식 연구에서 사용하는 자음과 모음 단위의 자소가 아닌 연결성분을 이용하여 인식하는 새로운 자소를 이용하였다. 새로운 자소들은 끝점, 2선 모임점, 3선 모임점, 4선 모임점의 특징을 추출하고 특징에 의해 자소를 인식하는 데이터베이스를 구성하여 자소를 인식하게 하였다. 또한 연결 성분을 반영한 새로운 자소로 고딕 인쇄체 문자를 인식하므로 추출된 자소를 6가지로 분류하였고, 6가지 자소에 의해 구성되는 92가지 문자 구조를 제안하고 이에 따른 문자를 데이터베이스를 구축하였고, 자소의 무게 중심을 이용한 분포를 이용하여 제안된 구조를 통하여 데이터베이스를 이용한 문자인식을 수행하였다.

Recent growth of ring-tone and ring-back-tone download market as the derived market of cellular phone yields the new trend in music consumption from listening to display. This means that consumer purchase the ring-tone and RBT not for his appreciation but for counterpart's consumption, in a word, conspicuous consumption. Study aims at questions on whether cellular phone user can perceive the ring-tone and RBT's brand personality and how they express their self-image via ring-tone and RBT. Survey was administered for 196 college students who is dominant purchase group of market segment. Hypotheses are such as : congruity of self image and brand personality of ring-tone and RBT. Through the T-test, findings said that user's extrovert self image are not led to ring-tone's extrovert brand personality and user's introvert self image are not led to introvert ring-tone's brand personality of ringtone. same result was applicable to RTB. Cellular phone user's purchase behavior are different from those of product and service.

Air transport markets are composed of airlines' networks through their base airports. The analysis of an air transport market has been focusing on determining the efficiency or competitiveness of airports or airlines in the market using number of routes, number of passengers, transfer rates, revenues, costs, and other data. However, little work has been done in analyzing the airport network itself. Assuming the air transport markets of Korea, China, and Japan are integrated, this paper aims to analyze the characteristics of the resulting airport network. To that end, the degree of connectivity, the degree of closeness, and the betweenness of centrality are employed. The analysis shows that Incheon International Airport is better than most other airports in terms of the degree of connectivity and that of closeness. Airports in Japan, however, exhibit strong connectivity but weak closeness and betweenness of centrality. Although it has low connectivity, Shenyang Airport has a possibility of becoming an attractive point of the integrated market in the future due to its high degree of closeness.

This study attempted to examine the structural characteristics of the social network of nursing units by dividing them into a job-related advice network and a friendship network, and to analyze the relationship between nurse organizational commitment and intent to leave. The subjects were 420 nurses working in 4 hospitals and 30 nursing units. Data were analyzed using UCINET 6.0, SPSS 20.0 and HLM 7.0. In job-related advice networks, degree centrality of head nurse contributed to organizational commitment. Network density contributed to intent to leave. In friendship networks, closeness centrality of head nurses and betweenness centrality of charge nurse contributed to organizational commitment. Density and betweenness centrality of charge nurses contributed to intent to leave. Accordingly, it is necessary to foster good relationships between nurses and to develop various types of strategies for building effective networks.

For global companies that are going to raise funds from international capital markets or to which lots of foreign investment are being given, it is necessary to prepare consolidated financial statements. This study provides the results of some analyses in accordance with the system of consolidated financial statements disclosure. First, disclosing those statements with audit opinion reflected would provide useful reliable and financial information. Second, such disclosure as foresaid would meet international standards that consolidated financial statements are used as main financial statements and separate financial statements as auxiliary ones. The disclosure system would make it possible for domestic corporations to introduce international accounting standards earlier, especially from 2009, in accordance with the road map of those standards. Third, the system of consolidated financial statements disclosure would play an important role in promoting the implementation of consolidated taxation systems under which corporate tax is levied in accordance with consolidated balance sheet.

This study was conducted to quantitatively analyze the temporal change of green space network at multi-scales from 1975 to 2006 with the application of graph theory in Seoul, Korea. Remarkable change of connectivity was detected in green space networks at the scale ranging from 1,000 ~ 1,600 m during 30 years. Green spaces and their networks have been restoring after 1990 since forest areas had been fragmented in 1975. In 2006, we identified the important core habitat areas that can sustain diverse wildlife species and stepping stones composed of small patches that can link these core habitat areas. Green spaces showed high correlation with the relative importance value of green space connectivity. So, this study could graphically represent green space networks of Seoul City. Green spaces of core areas distributed at the northern and southern boundary, and those of stepping stones possessing the high value of betweenness centrality consisted at the middle, eastern and western boundary. These results indicate that green space network can be graphically and quantitatively explained by degree centrality, betweenness centrality and relative importance value of connectivity with the application of graph theory.
