양계인의 소망이 생산물의 가격안정에 있고, 제도적으로 가격을 안정시키는 주체적인 역할을 할 수 있는 기구로 협동조합도 생각해 보아 왔다. 81년 1월 1일부터 발족되는 협동조합의 기본이 되는 협동조합법을 2회에 나누어 전문 계재코져 한다. 앞으로 축종별 전문조합인 양계협동조합도 탄생하여 그 운영이 활성화될 것으로 보여져 앞으로 시행령과 시행규칙이 발표되는대로 이도 본지를 통하여 독자들에게 소개할 계획이다.

정부는 광산업을 국가전략산업으로 광프로젝트를 추진하고 있다. 21세기 대표산업으로 광산업이 꽃 피우기 위해서는 중앙부처와 지방자치단체가 합심하여 광주에서 축을 형성, 광산업을 한층 발전시켜나가야 한다. 앞으로 정부는 국내시장을 비롯한 세계시장을 겨냥한 사업선정과 광산업 선진국인 미국,일본 등과의 네트워크 구축, 우수인력 유치와 양성을 통한 첨단기술 확보에 최선을 다할 계획...

김성훈 농림부장관은 3월 8일 농림부 대회의실에서 가진 기자회견을 통해 농.축협 일선조합과 중앙회에 대한 협동조합 개혁방안을 대통령에게 보고한 후 확정 발표하였다. 김 장관은 이날 기자회견을 통해 지난해 조합별로 구조조정 작업을 강도 높게 추진 한데 이어 "협동조합을 농민을 위한, 농민의 협동조합 그리고, 농민조합원의 진정한 봉사조직으로 거듭나게 하기 위해 협동조합개혁 방안을 차질 없이 추진하겠다"고 밝혔다. 이번 개혁안은 지난해 7월 정부가 농.축.임.삼협 등 4개 협동조합에 "협동조합개혁위원회"가 건의한 개혁안을 토대로 공동개혁안을 합의하여 제출토록 하였으나 합의에 도출하지 못함에 따라 정부에서 2001년까지 농.축협중앙회 통합 등을 포함한 근본적인 개혁작업에 나서게 되었다고 밝혔다. 한편 정부의 이 같은 방침에 대해 많은 축산농가를 포함해 축산관련 기관.단체 인사들과 축협노조는 협동조합 개혁에는 찬성하면서도 농.축협중앙회 통합에 대해서는 전문화 시대에 역행한다며 반대하는 여론이 높아 통합이 실현될지 여부가 주목된다. 다음은 김성훈 농림부장관이 이날 발표한 농.축협 등 협동조합 개혁방안의 주 내용이다.

The Basin, a marginal basin located between the Antarctic Peninsula and the South Shetland Islands, is consist of three small basins, the Central, Eastern, Western Basins. Seismic data obtained on December 1995 show well-defined spreading ridges, basement highs, faults, morphology of the basin, distribution of sediments, crustal and sedimentary deformation, diapirs, and contourites. The main spreading axis of the Central Bransfield Basin connecting Deception and Bridgeman Islands continues up to the central part of the Eastern Basin, whereas deep basin covered by thick sediments without any spreading structures develops in the northeastern part. This indicates that back-arc spreading along the axis of the Bransfield Basin has been taken place in the southwestern part of the Eastern Basin, not in the northeastern part. Many NW-SE trending faults perpendicular to the axis of the basin would be related with strike-slip movement of the Shackleton Fracture. Zone. Extensinal strutures like deep basin without any spreading structures in the northeastern part, normal faults and diapirs on both continental slopes of the Eastern Basin would be formed by extension as a consequence of the sinistral movement between Antarctic and the Scotia plates.

This paper presents a robust slewing control of a flexible space structure based on sliding surface design. A sliding surface is designed for a single-axis rest-to-rest slewing in view of target angle, target angular velocity, and root monent of the flexible appendage. In comparison with the Lypunov control law, both controllers guarantee the stability and command tracking capabilities for nominal system. It is also shown that the designed control law provides further robustness to internal/external uncertainties. Extending the results of a single-axis maneuver, a sliding mode control law was sought for an arbitrary three-axis maneuver. Quaternion was used to determine the attitude of a space structure and sliding surfaces were designed for each axis, thereby a robust control law was derived considering the coupling effects between each rotational axis during the maneuver. Several numerical examples were demonstrated to show the effectiveness of the designed control law.

A simple and rapid high-performance liquid chromatography assay for the determination of residual novobiocin levels in bovine, porcine, chicken, flatfish and japanese eel muscle has been developed and validated. The separation condition for HPLC/UV was optimized with phenyl hexyl ($4.6{\times}150mm$, $5{\mu}m$) column with 10 mM monobasic sodium phosphate buffer (pH 2.5)/acetonitrile (50/50, v/v) as the mobile phase at a flow rate of 1.0 mL/min and detection wavelength was set at 254 nm. Residues were extracted from tissue by blending with methanol and lipid materials were removed with n-hexane. Then, the methanol extract was evaporated to dryness under a nitrogen stream, reconstituted in the mobile phase. Aliquot of the organic extract was decanted and filtered through $0.45{\mu}m$ syringe filter. The $20{\mu}L$ of the resulting solution was injected into the HPLC system. The calibration ranges were $0.5{\sim}5{\mu}g/g$ and calibration curves were linear with coefficients of correlation better than 0.95. The limits of quantification were $0.5{\mu}g/g$ for all muscles. The recoveries of bovine, porcine, chicken, flatfish and japaneseel muscles were 99.8%, 102.4%, 91.0%, 104.0% and 93.0%, respectively. The procedures were validated according to the CODEX guideline, determining specificity, linearity, accuracy, precision, quantitation limit and recovery.

The complete, fully-elliptic Reynolds-averaged Navier-Stokes equations have been solved using a two-layer model, in the $\kappa-\varepsilon$ turbulence model, for the axisymmetric body. Numerically generated boundary-fitted coordinate system and the finite analytic methods are used to solve the governing equations. Calculations are started after the middle body with given inlet conditions. The velocities and the turbulent quantities at the inlet section are specified by solving the boundary layer equations or by standard flat-plate boundary profiles. The effects of the inlet conditions on the solution are investigated.

Park Wudang formally registered Daesoon Jinrihoe in 1969. While it shares ideas and history with other Jeungsanist groups, this paper argues that its organizational profile is unique. The two major institutional structures, the bonbu (headquarters) and the bangmyeon (branch) have together created space for the rapid development of this Korean new religion. The bonbu is a centralized hierarchy, while the bangmyeon exhibits the strong loyalty and cohesiveness of the clan. Running throughout both structural forms is the lineage concept, which is conceived here as an articulating paradigm able to operate in different organizational forms. This finely-balanced institutional structure makes a major contribution to Daesoon Jinrihoe's ability to fulfill its religious mission. The first side of this balance is the headquarters, which includes the core organization based in Yeoju as well as some outside temples and training centers. All of these were established under the direction of the Lord of Principle, the Dojeon, Park Wudang. Park Wudang also fixed the Dao Constitution, the Doheon, which serves as a blueprint for governance. From the Central Council to the various institutions for propagation, guidance, and auditing, current management practices conform closely to Park Wudang's organization vision. The second aspect of Daesoon Jinrihoe's organization is the branch structure. The larger branches, such as Yeongwol and Geumreung, are complex organizations in their own rights. The paper concludes by characterizing the two major axes of headquarters and branch as organizational types. Using Robert Quinn and Kim Cameron's institutional typology, the paper concludes that the bonbu is a classic centralized hierarchy with its focus on efficiency. The bangmyeon, in contrast, with its high level of group identity and spirit, comes approximates the clan institutional structure.

Elastic wave propagations in the semi-infinite transversely isotropic cylinder under various kinds of longitudinal impact loads are analyzed using the axisymmetric finite element method and Houbolt time-integration scheme. For which the finite element program is newly constructed and verified through the comparison of present numerical results with those by other researchers. E-type glass-epoxy composite cylinders with different fiber volume fractions are adopted and studied in detail with dynamic responses of the isotropic cylinder. Three dimensional wave motions are given in graphic form to show the realistic view of the wave propagation. Nondimensionalized dynamic characteristic variables which relate the size of finite element mesh, the time step, and the wave speed are presented for obtaining accurate and stable numerical results.

지그비(zigbee) 장비는 센서 네트워크 장비 중에서도 규모가 큰 축에 속하고 배터리로 동작하기 때문에 전력 소비가 큰 문제점으로 부각되고 있다. 지그비에서 비콘(beacon)을 사용하는 네트워크를 구성하면, 센서 장치들은 데이터 전송 빈도가 낮을 때도 중앙 데이터 처리기(coordinator)가 전송하는 비콘 패킷을 매번 받아야 하기 때문에 그에 따른 전력소모가 상당히 높다. 이러한 지그비 네트워크의 중앙 데이터 처리기와 주변 센서 장치(device)에 비콘 수신 주기를 동적으로 설정할 수 있는 프로토콜을 추가 함으로써 기존의 데이터 응답 속도를 유지하면서 전력 소모도 줄이는 방안을 제시하고자 한다.
