There are several manufacturing techniques for developing thermionic cathodes for vacuum ultraviolet(VUV) ionizers. The triple alkaline earth metal emitters(Ca-Sr-Ba) are formulated as efficient and reliable thermo-electron sources with a great many different compositions for the ionizing devices. We prepare two basic suspensions with different compositions: calcium, strontium and barium. After evaluating the electron-emitting performance for europium, gadolinium, and yttrium-based cathodes mixed with these suspensions, we selected the yttrium for its better performance. Next, another transition metal indium and a lanthanide metal neodymium salt is introduced to two base emitters. These final composite metal emitters are coated on the tungsten filament and then activated to the oxide cathodes by an intentionally programmed calcination process under an ultra-high vacuum(~10-6 torr). The performance of electron emission of the cathodes is characterized by their anode currents with respect to the addition of each element, In and Nd, and their concentration of cathodes. Compared to both the base cathodes, the electron emission performance of the cathodes containing indium and neodymium decreases. The anode current of the Nd cathode is more markedly degraded than that with In.

폴리메틸펜텐 막(polymethylpentene membrane, PMP)을 Ar, NH3 플라즈마로 표면 처리하고, 처리 전후의 투과 도와 선택도의 변화를 관찰하였다. Ar 플라즈마로 처리하였을 때 O/C의 비율이 증가하며 친수성기 (OH, COOH, C=O)의 도입이 확인되었고 NH3 플라즈마로 처리하였을 때 아민, 아미노기가 도입되었다. 플라즈마 처리된 폴리메틸펜텐막에서 CO2의 투과도와 N2,에 대한 선택도 (Actual Separation Factor)의 최적조건은 Ar 플라즈마 처리 (30 W-6 min)의 경우 각각 182 Barrer ［10-10;cm3(STP)cm/cm2.s.cmHg］와 6.17이며, NH3, 플라즈마 처리 (30 W-8 min)의 경우 각각 144 Barrer [10-10/cm2(STP)cm/cm2.s.cmHg] 와 6.13을 얻었다.

Non-point source pollutants have characteristics the render them difficult to manage owing to the uncertainty of flow paths. As agricultural non-point sources account for more than 57% of non-point source pollutants, the necessity for management is increasing. This study examines the possibility of utilizing land cover maps to suggest a more appropriate method of setting management priority for agricultural non-point sources in the Daecheong Lake area and draws implications by comparing the results derived using the cadastral map, as mentioned in the TMDL Basic Policy. To define the prioritized areas for management, the pollution load was calculated for each subbasin using the formula from the TMDL technical guidelines. As a result, the difference in the average pollution load between the land cover map and cadastral map ranged from 11.6% to 21% among the subbasins. In almost all subbasins, there were differences in the ranking of management priorities depending on the land information that was used. In addition, it was found that it was reasonable to use the level 3 land cover map to calculate the load generated by the land system for examining the implementation goals and methods of each data and comparing them with satellite images.

This study aims at choosing indicators to measure the effect of utilizing biotop map, and analyzing its effect by an indicator from the perspective of performer. The Primary performance indicators are made through specialist survey using SMART. As a result, three indicators are chosen: “Discussion of the period of an environmental effects evaluation(reduced effect)”,“Plan and execution of environment and ecology plan in an urban development site”,“Minimizing ecological damage in an urban development.” The result in each indicator is as follows. The indicator of discussion of the period of an environmental effects evaluation(reduced effect), the average reduction rate in statistically meaningful level reduced 6.08% and 11.64% respectively in 2004-2005. In this period, environment information system was established and the reduction effect is shown in this period by reinforcing environment effect estimation using biotop map. As to the indicator of utilizing biotop map in an urban development site, the Seongnam P site case shows that biotop map was used when they set up an development plan. In case of minimizing ecological damage in an urban development, the Gwangjingu G-dong case shows that it was used to appoint preservation sit, and mediate development restrict area. Accordingly, the biotop map utilizing effect is confirmed through core performance indicators and verification of the indicators using SMART. The further research is encouraged to find evaluate indicators and verify the effect quantitatively to increase the use of biotop map.

필자는 이 글에서 막스 베버의 유교론을 아래와 같은 관점에서 재구성하고 있다. 첫째， 베버는 서구에서 자본주의적 근대사회가 발흥하는 데는 개신교가 일정한 역할을 했다는 자신의 명제를 입증하기 위해 방대한 비교 종교사회학적 연구를 수행 하였으며， 이 연구의 일환이 그의 유교론이다. 둘째，그의 비교 종교사회학적 연구 프로그램은 크게 ‘기독교적’ 세계상과 ‘동양 종교적’ 세계상이라는 두 가지 이념형을 중심으로 구성되어 있으며，이 두 가지 세계상을 분석하는 틀은 (1) 세계상의 담지자층이 가진 ‘이해관계’ (interest)의 차원과 (2) 세계상 내재적인 ‘이념’ (idea) 논리 차원간의 상호작용관계에 초점이 맞추어져 있다. 셋째， 베버는 유교를 ‘실천적 합리주의’를 표방하는 대표적인 세계상의 하나로 규정하며 이것을 유교의 담지 자층인 사대부 집단과 중국의 가산제적 국가구조와 연계시켜 설명하고 있다. 넷째， 베버 유교론은 중국 문화에 대한 일련의 날카로운 사회과학적 통찰을 닫고 있지만， 동시에 그것은 적지 않은 편견과 잘못된 해석을 내포하고 있다.
