본 연구는 국내 상장기업 중에서 2000년에서 2002년도까지 사모사채를 발행한 124건의 발행 정보와 공모사채 발행을 실시한 203건의 발행정보를 표본으로 기업의 사모사채 발행에 영향을 미치는 결정요인들을 분석하였다. 회사채 조달원천의 선택에 영향을 미치는 요인으로 정보비대칭, 재무위험, 대리인비용, 독점적 정보, 신용등급 등 5개 변수를 도입하였다. 기업에 대한 정보비대칭의 정도는 사모사채 발행의 선택에 유의적인 영향을 미치는 것으로 나타났다. 이는 정보비대칭에 따른 역선택을 회피하기 위한 수단으로 사모를 선택하는 것으로 보인다. 또한, 기업의 재무위험의 정도가 클수록 공모사채 발행보다는 사모사채 발행이 이루어지는 경향이 높은 것으로 나타났는데, 이러한 결과는 사모계약이 가지는 재무적 재조정의 수월성과 관련이 있는 것으로 보인다. 대리인비용의 경우에는 대용변수의 선택에 따라 상이한 결과를 보이고 있다. 먼저, 주가수익률이 높은 기업일수록 사모발행을 통해 자본을 조달하는 경향이 높은 것으로 나타났다. 즉 사모발행은 부채의 대리인비용을 감소시키기 위한 수단이 될 수 있다고 추정된다. Tobin의 Q 경우는 기업의 공모사채와 사모사채 선택 의사결정에 유의적인 영향을 주지 않는 것으로 나타났는데, Tobin Q값이 높은 기업들은 강탈문제(hold-up problem)를 회피하기 위해 공모시장에 접근하는 경향이 있는 것으로 추정된다. 한편, 독점적 정보와 관련하여 기업은 내부의 정보보호를 위해서 사모사채 발행에 대한 동인을 가지는 것으로 보인다. 신용등급이 투기등급에 해당하는 기업들의 사모발행 경향이 높은 것으로 판단되었다. 본 연구의 결과들은 정보비대칭의 문제점이 있는 기업이거나 또는 대리인문제를 해결하기 위한 수단으로서 사모사채 발행은 기업의 우선적 자금조달방법이 될 수 있다는 것을 시사하고 있다고 할 수 있다.

Recently the demand for civil bodyguards and security guards shows rapid growth by the social development and improve the quality of life. However the supply and training system have some limitations in spite of the high demand guard-secretary. The main role of secretaries has been to accompany superiors in order to maintain their dignity or trait. But the secretaries are required to play additional roles of safety managers such as a security manager, a protocol manager, an intelligence manager and a protective driver in order to overcome the domestic and the international safety environment and to elevate the quality of service as a competitive work. So, the purpose of this article is to analyse current situation of civil body and security guard training industry and to seek an educational model. For it, the following questions will be examined. First, Do the professional training organizations meet social demand for the body and security guards? Second, What kind of training has to be provide for the body and security guards? and what the qualifications of the trainers? Then, what are the differences in training courses between private organizations and universities? Is there differences in the job placement among the trainers of private organizations and universities? etc.. In summary to meet the social demand common curriculum for the body and security guard will be drawn from the analyses of diverse training organizations with different training courses in contents, training periods, educational value, and social aim.

Background: In this research article, we evaluate the use of sub-periosteal tunneling (tunnel technique) combined with alloplastic in situ hardening biphasic calcium phosphate (BCP, a compound of β-tricalcium phosphate and hydroxyapatite) bone graft for lateral augmentation of a deficient alveolar ridge. Methods: A total of 9 patients with deficient mandibular alveolar ridges were included in the present pilot study. Ten lateral ridge augmentation were carried out using the sub-periosteal tunneling technique, including a bilateral procedure in one patient. The increase in ridge width was assessed using CBCT evaluation of the ridge preoperatively and at 4 months postoperatively. Histological assessment of the quality of bone formation was also carried out with bone cores obtained at the implant placement re-entry in one patient. Results: The mean bucco-lingual ridge width increased in average from 4.17 ± 0.99 mm to 8.56 ± 1.93 mm after lateral bone augmentation with easy-graft CRYSTAL using the tunneling technique. The gain in ridge width was statistically highly significant (p = 0.0019). Histomorphometric assessment of two bone cores obtained at the time of implant placement from one patient revealed 27.6% new bone and an overall mineralized fraction of 72.3% in the grafted area 4 months after the bone grafting was carried out. Conclusions: Within the limits of this pilot study, it can be concluded that sub-periosteal tunneling technique using in situ hardening biphasic calcium phosphate is a valuable option for lateral ridge augmentation to allow implant placement in deficient alveolar ridges. Further prospective randomized clinical trials will be necessary to assess its performance in comparison to conventional ridge augmentation procedures.

경호학과 또는 경호비서학과로 명칭 되는 민간시큐리티의 학과설치는 시민의 안전의식 증대와 밀접한 연관성을 갖고 있으며, 사회치안활동에 대한 경찰력의 물리적 한계를 보완하기 위한 조치로서 안전 전문인력 양성에 그 목적을 두고 있다. 시민의 안전지킴이로서 시큐리티 전문요원을 양서하기 위한 관련학과의 설치는 1995년을 기점으로 하여 2006년 현재 전국적으로 63개 대학(2년제, 4년제 포함)에서 설치${\cdot}$운영되고 있다. 물론 학과의 명칭은 다소 차이가 있더라도 학과가 추구하는 공통목표는 민간인에 의한 대민안전서비스 활동이다. 민간인 또는 민간기관에 의한 사회범죄예방 및 생활안전서비스는 이미 선진국에서는 보편화되어 사회의 중추적인 안전역할을 담당하고 있고, 경찰력인 공경비와의 보완적인 관계에서 독자적인 영역을 형성하고 있다. 그러나 아직 대학교육체계의 확립이 미흡한 실정이며 이로 인한 전문교육의 정착도 민간경비산업의 발달에 부응하지 못하는 측면을 나타내고 있다. 따라서 본 논문에서는 특히 현실적인 문제점으로 부각되고 있는 전문교육기관인 대학에서 전문 인력의 양성을 위한 교육과정의 본질과 차이성에 대한 분석을 함으로서 전문인력의 양성체계와 사회적 수요문제의 적합성을 논하려 한다.

University libraries aim to improve not only educational effects but also the general quality of colleges. A primary way of pursuing this goal is through providing professors and students with sufficient amounts of available references and materials that can be used for academic purposes. However, even though university libraries are intended to be used by college students majoring in different fields, they tend to provide mostly books. This limited offering of resources means that they are not distinguishing themselves from regular libraries. The purpose of this study is to present basic data for the spatial design of a subject specialization room in a college library. Included in the design are recommendations for the type and placement of the furniture in the room. The summary of results for this study and the conclusions are as follows: The layout of data space and reading space in a subject specialization room can be categorized into both document-oriented (document centralized and document categorized) and reading-oriented (reading centralized, all, and group types). The public reading seats and private reading seats in a subject specialization room, according to their ratio, can be divided into private reading, public reading, and distributed reading sections. The ratio of open-spaced tables is higher for groups of four or more people, but users often sit separately from others in order to ensure privacy. Unfortunately, this practice results in seating gaps that do not make efficient use of space. The result is that the public reading seats are less efficient than the private reading seats in terms of space. Therefore, it is necessary to increase the number of cubicles.

휴대폰 망과 같은 이동망이나 와이파이망, 주파수공용통신(Trunked Radio System)과 같은 망은 시설기반(Infra Structure)망이어서 핸드오버같은 것은 문제가 되지 않는다. 그러나 무전기 같이 수명에서 수십 명 내외의 그룹간 이동을 하면서 서로 통신을 해야 하는 경우는 망을 구성하고 있는 노드들이 실시간으로 이동하고, 토폴로지가 늘 변하고 있으며, 특히 무선으로 통신할 경우는 전파환경이 좋지 않아서 망을 구성하기란 쉽지 않다. 특히 특수목적망은 인프라 시설이 없어서 구성원들 간에 핸드오버(handover)가 필요한 경우가 많으며, 핸드오버하는 대상노드를 결정하는 것은 반드시 필요하며 중요하다. 어느 노드가 핸드오버 역할을 할지에 따라 다양한 토폴리지의 통달거리, 수신감도, 음질 등에 영향을 주게 된다. 본 고에서는 토폴로지 경우의 수를 다양하게 분석하여 전파간섭 및 핸드오버 프로토콜에 따라 데이터 전송을 원활하게 할 모델을 제시하고, 시뮬레이션을 통해 분석한 결과를 제시한다.

Partial edentulism has multiple implications in relation to function, esthetics and future rehabilitative treatment. This case report illustrates the management of a patient with extreme consequences of partial edentulism. The main clinical findings were unopposed remaining teeth, overeruption of the remaining teeth, loss of vertical dimension of occlusion, and significant disfigurement of the occlusal plane. Following the diagnostic procedure, a well-coordinated prosthodontic treatment involving liaison with other dental disciplines was indicated. The management involved an innovative combination of fixed and removable prostheses in conjunction with crown lengthening surgery and strategic implant placement. Series of provisional prostheses were applied to facilitate the transition to the final treatment.
