공동주택 리모델링은 유지보전과 개량보전이라는 두 가지 관점을 포괄하고 있다. 유지보전과 관련해서는 현재 장기수선계획과 특별수선충당금제도가 있으나 제대로 운용되지 못하고 있다. 그리고 개량보전을 위해서는 최근 관련 법의 개정이 이루어지고 있는 등 제도적 여건이 조성되고 있다. 향후 공동주택 리모델링의 활성화를 유도하기 위해서는 첫째, 특별수선충당금제도의 내실화를 위한 조세 감면 등의 인센티브 제공과 공익적인 기구의 설립을 통한 운영 등이 요구된다. 그리고 주민들의 실질적인 리모델링 욕구에 부응하기 위하여 세대수 증가, 내력벽 철거 및 발코니 용도 변경 등의 사안에 대해서도 전향적인 검토가 요구되고 있다. 또한, 리모델링에 대한 유인책 제공을 위한 조세 및 금융상의 지원도 필수적으로 요구되고 있다. 이밖에 중고주택정책, 재건축정책, 리모델링을 고려한 신축주택의 설계 지침 마련 등 여건 조성을 위한 관련 제도의 개선도 요구되고 있다.

In recent years, special concerns have been raised about the safety assessment of foods and food ingredients derived from genetically modified organisms (GMOs). A growing number of countries establish regulations and laws for GMOs in order to allow consumers an informed choice. In this case, a lot of methods have been developed for the detection of GMOs. However, the reproducibility among methods and laboratories is still a problem. Consequently, it is still in great demand for more effective methods. In comparison with the gel electrophoresis, the capillary electrophoresis (CE) technology has some unique advantages, such as high resolution efficiency and less time consumption. Therefore, some CE-based methods have been developed for the detection of GMOs in recent years. All kinds of CE detection methods, such as ultraviolet (UV), laser induced fluorescence (LIF), and chemiluminescence (CL) detection, have been used for GMOs detection. Microchip capillary electrophoresis (MCE) methods have also been used for GMOs detection and they have shown some unique advantages.

본 논문은 쿼드로터 무인기의 비선형 적응 자세 제어기 설계에 대한 것이다. 쿼드로터 무인기는 4 개의 추력기를 갖는 불완전한 비선형시스템으로써 모델 파라미터가 변화하기 때문에 특별한 제어기가 필요하다. 본 연구에서는 산업 응용에 따른 페이로드의 변화에 따라서 무인기의 모델파라미터가 변화하더라도 페이로드에 따른 튜닝을 자동으로 할 수 있도록 적응제어기를 설계하였다. 특히, 무인기의 수학적 모델을 이용하여 비선형 적응제어기를 설계하였고 리야프노프 함수를 이용하여 이론적으로 안정성을 분석하였고 페이로드 변화에 따른 시뮬레이션을 통해서 제어기의 성능과 파라미터 추정법칙의 유효성을 입증하였다.

이 연구는 판권기의 기능과 역할을 정리하고 중국에서 발행하는 도서의 판권기 변천사, 관련 법률, 기재요소 등을 살펴보았다. 중국의 도서 판권기를 살펴보면, 판권기에 공통적으로 들어가는 내용은 판권보호와 판본기록을 기재하고 있는 것이다. 판권기는 당해 도서의 서지사항을 특정한 곳, 즉 표제지 이면에 모아서 기재한 것이다. 그런데 이 판권기에 기술되는 서지사항은 출판기술의 발전과 출판환경의 변화에 따라 필요한 서지사항들이 추가로 기재되고 있다. 이 판권기는 도서관에서 목록을 작성할 때 유용한 정보원으로 제공되고 있다.

전자상거래에 관련된 국제적 논의는 OECD 등을 중심으로 이루어져 왔지만 최근에는 WTO의 역할이 부각되고 있으며, WTO에서 전자상거래의 논의는 주로 국제무역 관련 이슈들을 중심으로 이루어지고 있다. 하지만 여전히 전자상거래의 분류문제, 서비스의 분류, 관세부과, 공급모드, 지적재산권 문제 등 해결해야 될 문제들이 여전히 남아 있다. 이에 따라 우리도 전자상거래 관련 규정들을 마련하고 있으나 국제적으로 적용하기에는 한계가 있어 이를 발전시키고 활성화하기 위한 법제도 마련과 전략이 요구된다.

Korean city had been rapid developed through high industrialization and rapid economic growth after the 1970's. The city development process was guaranteed the fulfillment of city function through the city expansion based on New Towns and satellite cities rather than the reformation of existing city. This city expansion caused by degrading of city, being backward and producing many problems. To solve this problems, it was considered the rehabilitation of retarded function with rejuvenation such as a special law accelerating urban renaissance and reorganization project. Also a fire protection performance did not satisfied the required conditions of modern FPP system, such as the function deterioration of building facilities, the technological development with FPP facilities, changed fire laws and building occupancy for social needs. Insufficiency of requirements depreciated the building value and intimidated a safety of residents. To solve this problem, the improvement of FPP was essentially required and also strongly recommended an analysis and a comparative study between the required FPP of existing building and it improving effective FPP. Therefore, purpose of this study is that establish the basic data to construct a system to analyze and compare the building FPP.

This paper is devoted to the parameter optimization of unmanned aerial vehicle's (UAV) flight control laws. Optimization procedure is based on the ideas of mixed $H_2/H_{\infty}$ control of multi-model plants. By using this approach, some partial $H_2$-terms defining the performance of nominal and parametrically perturbed Flight Control System (FCS) responses to deterministic command signals in stochastic atmosphere as well as $H_{\infty}$-terms defining robustness of the FCS can be incorporated in the composite cost function. Special penalty function imposed on the location of closed-loop system's poles keeps the speed of response and oscillatory properties for both nominal and perturbed FCS in reasonable limits. That is the reason why this procedure may provide reasonable trade-off between the performance and robustness of FCS that are very important especially for UAV. Its practical importance is illustrated by case studies of lateral and longitudinal control of small UAV.

The purpose of this study is to examine the Marriage Preparation and Preservation Act adopted in Florida which require premarital counseling and covenant marriage laws of Louisiana and Arizona among many kinds of family policy which recently are designed to prevent divorce in the United States of America. Most of states in the U.S. require the marriage license prior to having a marriage ceremony. Covenant marriage legislation has admirable motives to strengthen marriage and cure the defects of the no-fault system. In that legislation, the imposition of waiting period for the no-fault ground of divorce, proof of fault requirements, consent requirements, and mandatory course or counseling attendance will likely serve as deterrents to those seeking divorce as a first resort. To sum up, by offering preventive measures in the form of premarital counseling and waiting period before marriage, covenant marriage will force couples entering marriage to carefully consider their actions before they act and prevent broken marriages in the first place. In response to rising divorce rates, the Koreas family policy has put its emphasis of fixing social problems accompanied with family dissolution. Rather, this study suggests that attention in Korea also should be shifted from broken marriages to preventing them.

Objectives : To direct methods of management and development of herbs and their derived products, and at the end of this study to inform the process of making new herbal drug regulations in Korea. Methods : This study analyzed the regulations and laws of western medicine drugs. Results : We have got some herbal prescriptions which are not in the eleven books of oriental medicine now in use but which have proved effective. We need to establish standards for permissions to produce medical products through those prescriptions. Besides, we need the special permissions to produce herbal products through prescriptions, especially those which have been used to treat incurable diseases. And, we can contribute to globalization of oriental medicine and to well situating of herb products and medicinal acupunctures if we produce them according to international standards. It is thought that herbal medicine has no side effect in the medical society in Korea. But, it is getting popular to administer herbal medicine and western medicine together. Thus, the side effects of taking both medicines at the same time should be documented. Conclusions : Herbal medicines and herbal products should be under the control over the whole process of production, circulation, and sales. Now, it is time for herbal medicine to be known to all over the world. Therefore, herbal medicine must meet and adhere to the standards set by the western society and WHO.

In this paper, a unified solution method is presented for the classical beam theory. In Strength of Materials approach, the geometry, material properties and load system are known and related with the unknowns of forces, moments, slopes and deformations by applying a classical differential analysis in addition to equilibrium, constitutive, and kinematic laws. All these relations are expressed in a unified formulation for the classical beam theory. In the special case of simple beams, a system of four linear ordinary differential equations of first order represents the general mechanical behaviour of a straight beam. These equations are solved using the numerical differential quadrature method (DQM). The application of DQM has the advantages of mathematical consistency and conceptual simplicity. The numerical procedure is simple and gives clear understanding. This systematic way of obtaining influence line, bending moment, shear force diagrams and deformed shape for the beams with geometric and load discontinuities has been discussed in this paper. Buckling loads and natural frequencies of any beam prismatic or non-prismatic with any type of support conditions can be evaluated with ease.
