본 환자를 간호하면서 절단으로 인해 신체적 고통을 받고 있는 존재로서, 생각과 정서, 욕구를 지닌 존재로서의 환자를 돕고자 시도해 보았다. 신체적인 적응을 돕기 위해서 근력강화와 관절가동역증진, 통증조절, 보조기 착용을 위한 단단의 관리, 잔여관절의 변형예방에 중점을 두었다. 심리적인 적응을 돕기 위해서 환자가 절단 수술과 수술 후 변화된 신체외모를 수용하는 과정을 증시했다. 끝으로 사회적인 면에서는 의미있는 사람들의 집단속에서 존재하는 인간으로서의 환자에게 관심을 두었다. 환자의 우측 슬관절 가동역은 완전히 회복된 상태는 아니지만 목발을 이용하여 걷거나 기타 일상생활을 하는데 불편함은 없으며 앞으로 계속적인 노력을 통해 회복될 수 있을 것이다. 그의 좌측 고관절 가동역은 정상유지되고 있으며 절단부위는 보조기 착용에 적합하게 형성되어 가고 있다. 비슷한 처지에 있는 이씨환자의 도움과 환자의 독립적인 생활태도는 환자가 자신의 불구에 적응하고 일상생활에 적응하는데 많은 도움이 되었다. 협조적이고 동정적인 환자들과 의료진의 도움으로 환자는 보호된 병원환경내에서 신체적 제한점을 주목하고 자신의 불구에 적응하면서 타인들과 원만한 관계를 유지해 왔다. 그는 앞으로 사회에 돌아가서 생활하게 될 것이다. 우리 사회는 아직도 그들에 대해 편견을 가지고 있으며 직업적 교육적 의료치료적 배려가 부족한 상태이다. 사회속에서의 적응은 병원에서의 적응보다 훨씬 더 어려울 것이며 때로는 그를 좌절하게 할 것이다. 그의 신체적 결함이 자기 자신만의 책임은 아니며 어느 누구나 사고에 희생될 가능성은 있다. 사회인들이 그들에게 관심있고 수용적인 태도를 지니고 그들의 정상 요구와 인간으로서 동등하게 살아갈 권리를 인정하고 받아들인다며 좀더 쉽게 자신의 슬픔을 극복할 수 있을 것이다.

Paper industry discharges many by-products and quantity of PSA (Paper sludge ash) has been increased. In this study, hydration water was added to PSA for use as cement admixture. PSA with added water was mixed with anhydrite and this mixture was used as cement substitute. Physical properties of PSA cement were changed by contents of PSA, but PSA cement containing PSA less than 10% had similar properties to those of OPC. Compressive strength of PSA cement mortar had a certain relationship with $Ca(OH)_2$ content. Compressive strength at 3 days increased, as $Ca(OH)_2$ content increased. However, the strength at 28 days increased, as $Ca(OH)_2$ content decreased.

이동통신 기술이 발전함에 따라 이동통신 네트워크를 통한 서비스들이 다양해지고, 사용자들의 수는 점점 늘어가고 있다. 또한 사용자들은 일반적으로 이동통신 서비스에 대해 유선 망과 동등한 수준의 품질을 기대한다. 그러나, 이동통신망은 유무선 통합망으로 구성되어 있으며, 이들 복잡한 구성을 갖는 네트워크에 대한 서비스 품질 보장은 유선망에 비해 훨씬 어렵다. 이의 결과로, 이동통신 서비스 네트워크의 트래픽은 과거에 비해 폭발적으로 증가하였다. 따라서, 네트워크 사업자와 서비스 제공자들은 서비스의 성능 문제에 직면하고 있으며, 네트워크 사업자나 서비스 제공자들은 효과적인 서비스 품질관리 기술을 강력하게 요구하고 있다. QoS 감시는 QoS 제공과 보장을 위한 기본적인 기술로서, 실제 네트워크에서 QoS 감시를 위해서는 네트워크 및 서비스 성능 인자들과 QoS 인자들의 관계를 식별해야 한다. 본 논문에서는 서비스와 네트워크 성능인자 그리고, QoS 인자들간의 관계를 QoS metrics로 정의하며, 각 인자들의 관계는 계층적인 그래프로 나타낸다. QoS metrics의 정의와 이에 따른 계층적 그래프의 구성을 통해 세 가지 이점을 기대 할 수 있다. 첫째, 네트워크 사업자들은 QoS 저하의 주요 원인을 신속하게 식별 할 수 있다. 둘째, 네트워크 사업자들과 서비스 제공자들은 주관적인 QoS 를 수치 적인 성능 지표를 통해 측정이 가능하다. 마지막으로, QoS metrics 는 네트워크 사업자들과 서비스 제공자들이 QoS 감시 활동의 결과에 따라 그들의 네트워크를 재구성하는 데 도움을 주며 E2E QoS 제공에 효율성을 가져다 준다.현을 정형화하기 위해 Oolong 코드의 명령어들을 문법으로 작성하였으며, PGS를 통해 생성된 어휘 정보를 가지고 스캐너를 구성하였으며, 파싱테이블을 가지고 파서를 설계하였다. 파서의 출력으로 AST가 생성되면 번역기는 AST를 탐색하면서 의미적으로 동등한 MSIL 코드를 생성하도록 시스템을 컴파일러 기법을 이용하여 모듈별로 구성하였다.적용하였다.n rate compared with conventional face recognition algorithms. 아니라 실내에서도 발생하고 있었다. 정량한 8개 화합물 각각과 총 휘발성 유기화합물의 스피어만 상관계수는 벤젠을 제외하고는 모두 유의하였다. 이중 톨루엔과 크실렌은 총 휘발성 유기화합물과 좋은 상관성 (톨루엔 0.76, 크실렌, 0.87)을 나타내었다. 이 연구는 톨루엔과 크실렌이 총 휘발성 유기화합물의 좋은 지표를 사용될 있고, 톨루엔, 에틸벤젠, 크실렌 등 많은 휘발성 유기화합물의 발생원은 실외뿐 아니라 실내에도 있음을 나타내고 있다.>10)의 $[^{18}F]F_2$를 얻었다. 결론: $^{18}O(p,n)^{18}F$ 핵반응을 이용하여 친전자성 방사성동위원소 $[^{18}F]F_2$를 생산하였다. 표적 챔버는 알루미늄으로 제작하였으며 본 연구에서 연구된 $[^{18}F]F_2$가스는 친핵성 치환반응으로 방사성동위원소를 도입하기 어려운 다양한 방사성의 약품개발에 유용하게 이용될 수 있을 것이다.었으나 움직임 보정 후 영상을 이용하여 비교한 경우, 결합능 변화가 선조체 영역에서 국한되어 나타나며 그 유

In this study, the different unit cement content by the ratio of water absorption and water-cement ratio are applied to examine the properties of the concrete used the aggregate recycled by the crushing treatment. According to the experimental results, in the mix of low strength and high water-cement ratio, both of the compressive strength is almost equal in the concrete using the recycled aggregate by the crushing treatment and the concrete using broken stones. It means that the recycled aggregate has the low effect of the amount of bonded mortar. But, in the mix of high strength and low water-cement ratio, the concrete using the recycled aggregate by the crushing treatment has 40% less of the compressive strength than that using broken stones by the effect of the amount of bonded mortar. On the other hand, after 8 weeks, the dry shrinkage of the recycled aggregate with 7% of the ratio of water absorption doubles that of the broken stones with 1% ($-350{\times}10^{-6}$), in other words $-700{\times}10^{-6}$. Thus, the dry shrinkage should be prior to any other conditions in recycling waste concrete for the aggregate for concrete. When the recycled aggregate with 3% of the ratio of water absorption is used, the compressive strength of the rich mix concrete ($450kg/m^3$ of the unit cement content) is equivalent to that of the concrete using broken stones, while in using the recycled aggregate with 7% of the ratio of water absorption, the rich mix concrete has 7% lower compressive strength than the concrete using broken stones. But, the compressive strength of the ordinary mix concrete ($350kg/m^3$ of the unit cement content) is far lower than that using broken stones.

Fuzzy control is widely used for improving temperature control performance as controlling ventilation in greenhouse because the technique can respond more flexibly to the outside air temperature and wind speed. By pre-studied PID and normal fuzzy control this study was performed to obtain the fundamental data that can be established in better greenhouse ventilation control method. The temperature control error by the simple fuzzy control was $1.2^{\circ}C$. The accumulated operating size of the window and the number of operating were 84% and 13, respectively. These showed equivalent control performance with pre-studied result that control error. The accumulated operating size of the window and the number of operating were 75% and 12, respectively. The proposed fuzzy technique was simple control logic method compared with step and PID control methods, but it showed equivalent performance. Therefore, the proposed simple fuzzy control method could be used in micro controller of small programmable memory size and many applications.

Assessing values in establishing conservation principles has been at the heart of discussions for the last twenty years since conservation has been recognised as a social process to include various kinds of stakeholders for making a rational decision rather than a single scientific activity by a small group of experts. Such perception makes values attributed to cultural heritage important in deciding the reason why, the way how to, and the thing what to conserve making value assessment become crucial theme to understand and developing value-based conservation process. However heritage values, the way of assessing them, and establishing value-based conservation principles have been less studied in Korea. This thesis aims to initiate studies of heritage values and encourage discussion for setting out value-based conservation principles. It has three main chapters: 1. to analytically review previous studies on value assessment to redelineate various kinds of values which can be attributed to Korean cultural heritage; 2. to examine affecting factors in assessing values and significance, which are authenticity and historical and cultural dimension of value assessment; 3. to develop a process to establish value-based conservation principles. This study left several areas to be developed in future studies: 1. deeper understanding of various kinds of values from local perspective taking actual cases; 2. addressing problems in compromising conflicting values and providing solution to conserve all attributed values withing devaluing certain aspects of values; 3. providing guidance for practicing value - based decision - making process and setting out regular training opportunities for heritage - related professionals.

This research conducts a series of tests to investigate the setting retarding properties and strength development in cement pastes incorporating various types and dosages of sugar-based super retarding agents. Six such agents, including Sucrose, Sugar powder, Saccharin, Aspartame, Stevioside, and Mogroside, commercially available, were selected for evaluation. The study also examines the micro-structural properties of these cement pastes. The test mixtures were prepared using a 27.5% water-to-cement ratio and ordinary Portland cement. Micro-structural analyses were conducted using Scanning Electron Microscopy(SEM), X-Ray Diffraction(XRD), and Energy Dispersive Spectroscopy(EDS). The findings reveal that the incorporation of sucrose, sugar powder, and stevioside significantly retards the setting time. Particularly, adding 0.1% sucrose extended the setting time by approximately two-fold compared to the control(Plain) mixture. Most mixtures, barring those with sugar powder and stevioside, exhibited compressive strength comparable to the Plain mixture. Notably, with 0.2% sucrose, strength measurements were not feasible at 1 day, but at 3 days, the strength gains aligned with the Plain mixture. XRD, SEM, and EDS analyses confirmed the hydration delay(set retarding) of C3S due to sucrose, with further quantitative corroboration provided by EDS. SEM was used to verify the presence or absence of hydration products. The study concludes that sucrose, as a sugar-based retarder, offers effective set retarding capabilities and compressive strength development in concrete.

Anaethetics are needed for handling fish, especially for transportation, tagging and grading. Among them, MS-222 has been popular in aquaculture since it has an excellent anaesthetic effect. However, MS-222 is more expensive than other chemicals. Benzocaine (Ethyl-p-aminobenzoate) has a similar molecular formula and equivalent anaesthetic effect to MS-222, and is cheaper. The purpose of this study was first to compare anaesthetic effects (Benzocaine) under various conditions : temperature, concentration, pH and body weight. Second purpose was to compare actual anaesthetic effects at 50 ppm benzocaine at ambient temperature and pH for the grading of tilapia. The results of this study are as follows : 1. The effect of anaesthesia at $24^{\circ}C$ was better with low pH, that is 5.6 than high pH 6.6 and 7.6. 2. The anaesthetic effect was not different at different body weight form 11g to 1,350g. 3. The fish were anaesthetized in 4~10 minutes at 50 ppm benzocaine at temperature. $20{\sim}24^{\circ}C$ and pH 6.8~7.3 and recovered in 4~6 minutes when they were put back in the fresh water after 30 minutes anaesthesia. 4. Benzocaine was more sensitive at pH fluctuation than temperature. 5. Twenty four hour-TLm of Benzocaine was 50 ppm at $24^{\circ}C$, pH 6.8 when the fish were put back in the fresh water after 120 minutes.

Fourteen healthy volunteers ranged in ages from 20 to 30 were served to administrate two types of yoghurt (2 bottles/day) such as one added uncapsulated-Bifidobacteria (Y-UCB) and the other added capsulated-Bifdobacteria (Y-CB) for 4 weeks, and the changes of intestinal microflora and fecal properties were studied. After administration of Y-UCB, the viable cell counts of fecal Bifidobacteria (p<0.01) and Lactobacilli (p<0.05) were significantly increased, however, fecal pH, moisture content and tile viable cell counts of coliform bacteria in feces were not changed when they were compared to those before administration (control). After administration of Y-CB, the viable cell counts of Bifidobacteria were significantly increased (p<0.01) and viable cell counts of coliform bacteria were significantly decreased (p<0.05), however, fecal pH, moisture content, and viable cell counts of Lactobacilli were not changed when they were compared to those before administration. High level of fecal Bifidobacteria and low pH were maintained after 2 weeks from ceasing the administration of both types of yoghurt when they were compared to those before administration. In conclusion, there were not significant differences between two types, Y-CB and Y-UCB in the changes of fecal pH, moisture content, and the viable cell counts of Bifidobacteria, Lactobacilli, coliform bacteria after the administration.
