Bi₃zsLa(0.75)Ti₃0_(12) (BLT) thin film have been grown on p-type Si(l00) substrates by a sol-gel spin coating process. The structure and surface morphology of the film were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEMI. Furthermore, the electrical properties were examined by capacitance-voltage ( C-V) characteristics by using a LF Impedance Analyzer(HP 4192A). XRD measurement show layered perovskite structure with a single phase in BLT thin film annealed at 700C for 30 min in oxygen. The measured grain size of BLT on Si is about 0.04 - 0.1 pn. From the cross-sectional SEM image, BLT film thickness is measured to be 0.4 pm. The C-V characteristic hysteresis curves show that the NIFS (metal-fexroelectric-semiconductor) structure has memory effect. The memory window decreases, with increasing frequency at MFS structure. And it is found that the memory window increases as the applied voltage to the ferroelectric capacitor is increased. These phenomena may be due to polarization reversals of the BLT ferroelectric film and because of the charge injection from Si substrate into the ferroelectric thin film. The results obtained indicate that the present BLT films are suitable for making ferroelectric field effect transistor(FeFET) memory.

This study was managed to develope the existing numerical calculation model of near shore current and wave fields where wave and current coexist around shallow water region, and analyse their problems. Until now, nearshore current model that include longshore current and on-off shore current had shown wave characteristic based on regular wave theory. In this study, however, nearshore current characteristic was changed by directional dispersion. So the effect of directional dispersion of multidirectional irregular wave was examined numerically by the basic study of nearshore current calculation due to multidirectional wave that was driving force of pollutant material at shallow water region.

Bismuth layered structure ferroelectric thin films, BIT and donor (V, Nb and W) doped BIT, were prepared on the Pt/Ti/SiO2/Si substrates by sol-gel method. BIT film was characterized by strong c-axis prepared orientation. In the case of donor doped BIT thin films, the degree of c-axis prepared orientation decreased systematically V-BIT→W-BIT→Nb-BIT and Nb-BIT film was shown random orientation. Surface morphologies of BIT and V-BIT films had a plate-like and Nb-BIT and W-BIT had a mixture of plate-like and rod-like. In the results of ferroelectric hysteresis loops, the remanent polarization (2Pr) of random-oriented Nb-BIT capacitor was 26 μC/cm2, and this value was over two times higher than that of 12 μC/cm2 for BIT capacitor. The polarization fatigue up to 4.5×1010 read/write switching cycles of W-BIT capacitor was shown superior to the other capacitors. The polarization of the W-BIT capacitor decreased only 10% of the initial value after 4.5×1010 switching cycles.

Effects of alkaline, ozone, and combination of alkaline and ozone pretreatments on the biodegradability of sewage sludge were investigated. Solubilization efficiency in terms of SCOD production was higher in the order of the sludge treated with both alkali and ozone, alkali, ozone. Alkaline pretreatment was performed at pH 12 for 3hr and ozone dosage was 0.02 or 0.05 gO₃/gSS. When the sludge was treated with ozone without alkali addition, the solubilization efficiency increased with the ozone dosage. Batch tests were conducted using activated sludge as a seed and pretreated sludge as a feed. The highest biodegradability could be obtained when the sludge was treated with both alkali and ozone. Biodegradability of the pretreated sludge showed linear relationship with the solubilization efficiency, suggesting that the solubilization efficiency be a useful index to evaluate the biodegradability of the pretreated sludge. Production of carbon dioxide during the batch tests also indicated that the alkaline followed by ozone pretreatment showed the highest efficiency for the biodegradability of the sludge.

휴전선 인접 마을의 새마을운동 사례를 통해 본 1970년대 한국 농촌사회 정치·경제적 변화 : 강원도 철원군 사곡2리와 군탄1리를 중심으로

이 논문은 1970년대 권위주의 유신체제 하에서 농촌근대화를 목적으로 추진되었던 새마을운동이 한국 농촌사회에 어떠한 정치적·경제적 변화를 초래하였는지 살펴보는 것을 목적으로 한다. 실증적인연구제시를 위해 강원도 철원군 근남면 사곡2리와 갈말면 군탄1리 두 마을의 새마을운동을 사례로 분석하였다. 이 사례연구는 한수이남에 집중되어 있던 기존 새마을운동 연구의 공간적 범위를 휴전선인접지역까지 확장시켰다. 1970년대 당시 두 마을 새마을지도자들과의 인터뷰 자료와 현재 마을회관에 남아 있는 새마을운동사업 기록을 토대로 마을간 사업추진 방식과 두 마을 주민들의 참여태도, 사업성과 둥을 분석하였다. 철원군 근남면 사곡2리와 갈말면 군탄1리의 새마을운동 전개양상은 마을의 입지조건 및 마을 구성원의 차이에 따라 상이한 결과로 나타났다. 사례연구의 케이스가 협소하긴 하지만, 이 연구를 통해서 새마을운동이 직 ·간접적으로 농촌사회에 가져온 변화를 찾을 수 있었다. 새마을운동은 마을 단위로 진행되었기 때문에 동일 지역에서도 마을구성의 상이한 조건적 차이로 인해 새마을운동의 결과도 다르게 나타났다. The objective of this thesis is to see political and economic changes in Korean rural society in 1970s when Saemaul Undong(Movement) was launched by authoritarian government for the modernization in an agricultural district. This paper focuses on Saemaul Undong in two villages of Cheorwon, Kangwon Province or Sagok2-ri and Cuntanl-ri in order to provide actual evidence. Based on the interviews of two towns' then Saemaul Leaders and the information on Saemaul Undong of those areas during the 1970s, this research analyzes people's attitudes, the way of the Movement and the achievement of the Movement. In addition, this paper emphasizes on some changes in political and economic areas of the two villages for about 8 years, comparing to before and after the movement being implemented. They have similarities as well as differences in the stages of Saemaul Undong. firstly, it led the dwellers to actvely participate in the process. Secondly, the residents could express their opinion to the government through the town meefngs. Thirdly, newly-elected leaders, called Saemaul Undong leaders were main actors who are at the center of the course. Although they took the helm just within the Saemaul Undong project, their capacities resulted in various consequences of the Movement under the autonomy of the town unit. Apart from other changes, it altered the appearances of the rural communities. It came to build new roads, convert old houses to modernized ones. It is difficult to say that Saemaul Undong has drawn the actual increase in the economic incomes. However, development in the repairing facilities in it played a key role in going up in the crop productivity, Therefore, it is fair to say that Saemaul Undong had a positive effect on the agricultural economy to some extent.

Background : About 30% of patients in the hospital are under nourishment. A large portion of people are undernourished when they are admitted to the hospital and in the majority of these, undernutrition develops further while in hospital. Patient-Generated subjective global assessment(PG-SGA), a method of nutritional assessment based on clinical judgment, has been widely used to assess the nutritional status of adults for both clinical and research purposes. Modified PG-SGA can be used as a nutrition screening tool, and a comprehensive nutrition assessment is desirable for those who are malnourished. The purpose of this study is to develop a simple, reliable and valid nutrition screening program(NSP). Methods : We applied the nutrition screening program(NSP) to adult inpatients who are at risk of malnutrition using the Modified Patient-Generated subjective global assessment(PG-SGA) and objective assessment(electrical medical record data). Results : Therefore simple and beneficial NSP is developed for patients with severe malnutrition. Using NSP. nutritional information of the severe malnutrition patient should be shared with the physicians and they should be taken care of by clinical dietitians to improve their nutritional status. Conclusion : The Modified PG-SGA and nutrition screening tool are simple, reliable and valid nutrition screening program(NSP).
