This study was conducted to establish collaborative governance for North Korean Refugees' settlement support service. Three major actors were identified. At the central government level, there is no control center to coordinate various functions. This study suggested three roles for central government in collborative governance, which are policy planning based on public value, allocating financial resources to implementing organizations, and program evaluation for securing public accountability. The rloes of local government are establishing communication channels between implementing participants, maintenancing good relations, and coordination. Finally, the role of private actors is developing high quality service programs, connecting local resources for settlement service.

본연구(本硏究)의 으뜸가는 목적(目的)은 우리나라에 있어서 단기경기조정(短期景氣調整)을 위한 통화금융정책(通貨金融政策)의 수립(樹立)에 도움이 될 수 있는 소규모(小規模) 계량모형(計量模型)을 만드는 것이다. 그 목적(目的)을 위해 본연구(本硏究)에서 원용(援用)한 모형(模型)은 기본적(基本的)으로 통화론적(通貨論的) 접근법(接近法)을 따른 것이다. 즉, 경제(經濟)의 조정과정(調整過程)에 있어서 화폐시장(貨幣市場)의 불균형(不均衡)이 가지는 핵심적(核心的)인 역할(役割)에 초점(焦點)을 맞추고, 이를 중심(中心)으로 물가(物價), 국민총생산(國民總生産), 국제수지(國際收支)가 동시적(同時的)으로 결정(決定)되게 하는 것을 그 기본골격(基本骨格)으로 하고 있는 것이다. 그 다음 모형(模型)의 타당성(妥當性)을 검토(檢討)하기 위해서 전정보최우법(全情報最尤法)에 의하여 모형(模型)을 추정(推定)하였으며 그 추정결과(推定結果)를 이용(利用)하여 각종(各種) "시뮬레이션"을 실시(實施)하였다. "시뮬레이션"의 결과(結果)는 70년대(年代)의 급변(急變)하는 경제여건(經濟與件)에도 불구(不拘)하고 상당히 만족(滿足)스럽게 나타났다고 할 수 있다. 마지막 부분에서는 국내여신(國內與信) 및 환율정책(換率政策)의 파급효과(波及效果)를 분석(分析)함으로써 국내여신(國內與信)의 무절제(無節制)한 팽창에 대한 경계(警戒)와 좀더 탄력적(彈力的)인 환율정책(換率政策)의 필요성(必要性)을 주장(主張)하였다.

We made a regression analysis on the early IPO of venture capital investments in Korean IPO market. First, we found that it was likely to shorten the period to IPO in companies which were fast growing with a good operating cash flow, but these companies had a higher possibility of the earning management. Second, companies with more assets and larger size of the board of directors did not take companies public any earlier. Third, a better corporate governance also had no impact on the time period to IPO in the newly public firms. The findings above clearly show that venture-backed companies in Korea pursue the tendency of an early IPO. This phenomenon was much clearer when the companies were invested in by multiple venture capital firms than by a single investor. In general, venture capital firms invest in companies which are fast growing and which have a good operating cash flow. On the other side, venture capitals make investee companies go public earlier by manipulating operating earnings, so that they themselves may exit early. In conclusion, this research has shown that venture capitals in Korea do not play a positive role in the corporate transparency. This is the paradox of venture capital investment and this also shows the current status of Korean venture capital firms.

This paper aims to explore the cause and aspect of inter-ministerial policy conflict and its coordination in science and technology policy-making with the case of science and technology basic law-making process in Korea. This law-making processes are analysed through the three periods for the last 10 years starting 1992, such as law-formulation(1st) period, interim law-making (2nd) period, and final law-making(3rd) period. Based on these steps, it tries to concretely describe the phenomenon of policy conflict and the coordination mechanism among government departments and analyses the characteristics of dynamic interaction and mutual adjustment among the related agencies. The analysis is mainly focussed on the underlying causes and determinants of policy conflict, the development and coordination process of the conflict, the strategies and logics of the conflict participants, and eliciting some policy implications for effective policy coordination among government departments. Research results are summarized as follows. First, in science and technology policy-making the main causes of policy conflict among government departments are attributed to the difference of policy-orientation and jurisdiction-orientation of each agency. During the first period, the main aspect of policy conflict was policy-oriented, during the second, the main aspects of policy conflict were both policy-oriented and jurisdiction-oriented, and during the third, policy-oriented conflict was dominant. Second, the dominant typology and strategies of policy coordination which the participants used were vertical-political and horizontal-analytic approach. During the first period, horizontal and analytical approach were used, during the second, horizontal and political approach are mixedly used, and during the third, vertical and political approach were dominantly used. Third, The Korean National Assembly and the ruling party played a pivotal role in science and technology policy-making process(the basic law-making process) in particular during the final period.

This study analyzes the earnings management that can occur in the process of public offering in the process of SMEs reducing cost of capital, risks and seeking opportunities for direct financing. Since a company is subject to strict supervision during the IPO process, it is possible to prevent the phenomenon that the company value evaluated in the market is underestimated, or to perform earnings management in consideration of overestimation. This study attempted to verify the degree of earnings management through discretionary accruals and actual earnings management values that can affect the earnings ratio of the IPO of a company. For this study, total accruals were calculated and analyzed through discretionary accruals, sales, costs, and actual earnings management adjustments from production activities. As a result of the analysis, discretionary accruals, which are the countermeasures for earnings management during the listing process, have a positive(+) relationship in both the stock price return and the sales adjustment value, which can be viewed as a factor that induces high valuation. As a result of this, there may be a risk of adverse selection for the benefit amount, and information asymmetry may exist for public offering stocks. This study can provide useful guidelines for evaluating corporate value to domestic SMEs and investors that do business with Chinese companies as well as China through the current and type of earnings management of Chinese listed companies.

본 논문은 의미 중의성 해소에 있어서 품사 태깅의 중요성을 언급한 Wilks의 논문 [6]을 근거로 하여 한국어 의미 중의성 해소에 있어서의 품사 태깅의 역할을 살펴보고, 영어의 경우와 비교, 분석한다. 한국어 사전과 코퍼스를 각각 대상으로 품사 태깅을 이용한 의미 중의성 실험 결과, 한국어의 경우는 영어의 경우보다 품사를 이용한 의미 중의성 해소율이 떨어지는 결과를 보이고 있다.

The technology of Broadband LAN is required to unify, control and manage various infromation devices by sharing resources. This technology is applied for tele-conferencing, tele-control, tele-metering and 2-way CATV etc. besides Computer network by using multiple channels. This paper introduces the technology and cases of Broadband LAN which is the subnet of ISDN and the basis of FA and OA as the key-technology of MAN(Metropolitan Area Network) and WAN(Wide Area Network).

본 논문에서는 N개의 평행 결합선로를 이용한 3dB 결합기를 해석하였으며, 유도된 식에 의하여 최소의 단수와 크기로 3dB 결합기를 설계하였다. 기존의 Spectral Domain상에서 N단 평행 결합선로의 복잡한 관계식 유도를 S 파라미터 관계식으로 간단히 유도 하였으며, 유도된 식의 타당성을 위해 실제 제작 검증하였다. 제작된 결합기는 Loose coupling의 평행 결합 선로의 광대역 특성을 그대로 이용하기 때문에 Lange Coupler와 같은 높은 임피던스와 Tight coupling을 구현 할 필요가 없으며, wire bonding도 용이하게 된다. 최소의 단수로 구현하기 위해 RT/Duroid의 R06006과 같은 높은 유전율과 두꺼운 기판을 사용하여 2단으로 3dB 구현이 가능하게 하였다. 제작결과 3.6GHz에서5.5GHz로 대략 42%(0.5dB imbalance) 정도의 광대역특성을 가지고 위상오차도 1$^{\circ}$내외의 결합기를 구현할 수 있었고 격리도 특성 또한 대역 내에서 15dB 내외의 특성을 보였다.

The MUSIC(MUltiple SIgnal Characterization)algorithm has been extenced to the UCERSS(Unit Circle Eigendecomposition Rational Signal Subspace) by taking eigendecimposition on the unit circle in order to estimate incident angles of multiple wide band signals. The purpose of this paper is to presetn SSB-UCERSS(Signal Subspace Based UCERSS) and SS-UCERSS(Spatially Smoothed UCERSS) estimating the incident angles of multiple side band signals in multipath(coherent signals) environments. Computer simulation results indicate that SSB-UCERSS yields the best result, while the SS-UCERSS performs better than the UCERTSS in a multipath environment.
