국제 무역시대의 도래로 항만 물동량이 크게 증가함에 따라 항만시설의 확충이 시급한 실정이다. 비교적 양호한 지반에서의 항만공사는 종래에 대부분 행해졌으며, 현재는 아주 연약한 지반에서의 해안매립을 통한 부지조성 등의 대규모 공사가 진행중이다. 연약지반 성토시 하부지반은 압밀침하와 전단변형이 동시에 발생하므로, 양자를 고려한 안정성 판단이 매우 중요하다. 본 연구에서는 현장에서 파괴가 발생한 부산 신항만공사의 서방파제 계측결과를 분석하고 수치해석을 수행하여, 면적비 안정관리기법을 제안하였다.

To develop the functional pear fruitlet product, we prepared dried pear fruitlet and fermented pear fruitlet, respectively. Then we investigated their general characteristics, and viable cell number changes during the storage at room temperature. We also determined preference for their tastes. Dried pear fruitlet contained more ash and crude proteins as well as minerals than fermented pear fruitlet. However fermented pear fruitlet contained higher amount of edible fiber than dried pear fruitlet. Fungi were not detected from dried pear fruitlet during the storage experiment at room temperature. Numbers of bacteria from dried pear fruitlet were increased from 1.1☓105/g at the beginning to2.6☓106/g at the last day of experiment. When we determined change of fungi number during the storage of fermented pear fruitlet, we cannot detect fungi at the beginning but we detected 4.4☓102/g of fungi at the last day of storage experiment. Bacteria from fermented pear fruitlet were detected at around 1.0☓109/g during the storage periods. Preference for fermented pear fruitlet was superior to dried one.

Changes of Calbindin D-28k- and c-fos-immunoreactivities in the superior collicuclus after Eye Enucleation. Objective and methods: Calcium-binding proteins (CBPs) play an important role in the protection, differentiation and reorganization of the central nervous system. The effects of neonatal retinal deafferentation on a CBPs, calbindin D-28k were examined immunohistochemically in the superficial layer of the rat superior colliculus. Also early gene familly c-fos was examined to evaluate the neuronal characteristics in the superior colliculus after monocular enucleation. Results: On the experimental side of superior colliculus, the number of calbindin D-28k-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. Appearance of c-fos-like immunoreactivity was represented much more in the ipsilateral superior colliculus than contralateral side within 24h after eye enucleation. Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of calbindin D-28k and c-fos expression.

Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2-3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain service lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement, and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent, outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

The effective removal of sewage sludge is very wmportant, due to a lot of generation, environmental hai mful effects. This study was carried out to be effective pretreatment of cell rupture. The purpose of sludge pretreatment in this study was that microorganism cell walls of sewage sludge were ruptured by biochemical and mechanical treatment for sewage sludge reduction. the soluble chemical oxygen demand and solubility of sewage sludge gradually were increased with SDS, lysozyme and EDTA dose. Also treatment of combined lysozyme with SDS or EDTA more increase of SCOD concentration than singy' treatment method. The sludge cells and floc were disrupted by homogenizer and biochemical pretreatment resulting in the increase of SCOD concentration and microscopic observation. We have observed that higher solubility of sewage sludge cloud be obtained through pretreatment of combination homogenizer with enzyme.

In this paper, cell-mediated immune algorithm(CMIA) controller was proposed and applied for the autonomous guided vehicle(AGV) driving. It was based on specific immune response of the biological immune system which is the cell-mediated immunity. To verify the performance of the designed CMIA controller, some experiments were performed for the control of steering and speed of AGV. And then the displacement and speed tracking error of the AGV was mainly investigated. As a result, the capability of realization and reliableness were proved by comparing the response characteristics of the classical controller with the proposed CMIA controller

Objectives : Narcolepsy is a sleep disorder, characterized by excessive daytime sleepiness, cataplexy, sleep paralysis and hypnagogic hallucination. Among these symptoms, cataplexy is one of the most pathognomonic symptoms in narcolepsy. This study was designed to investigate the clinical features, frequency of DQB 1 *0602 and CSF hypocretin levels in Korean narcolep-tics with cataplexy to compare with those who have not cataplexy. Methods : From August 2003 to July 2005, we selected 72 patients who have narcolepsy confirmed by nocturnal Polysomno-graphy and multiple sleep latency test (MSLT) as well as their history and clinical symptoms at Sleep Disorders Clinic of St. Vincent's Hospital, Catholic University of Korea. Patients were divided into 56 cataplexy-positive group (narcolepsy with cataplexy group) and 12 cataplexy-negative group (narcolepsy without cataplexy group). HLA typing was done in all patients for the presence of DQB 1*0602, and patients received spinal tapping to measure the level of CSF hypocretin. Clinical variables were examined by semi-structured interview for narcolepsy patients. Results : 1) In cataplexy-positive group, compared with cataplexy-negative group, the frequency ofHLA-DQB 1*0602 was found to be significantly increased (50 subjects, 89.3% vs. 8 subjects, 50.0%) (p=0.000). 2) tn 48 out of 56 cataplexy-positive patients (85.7%), hypocretin levels were decreased (≤110 pg/mI) or were below the detection limit of assay (≤40 pg/ml).However, only 6 out of 16 cataplexy-negative patients (37.5%) exhibited decreased hyopcretin level. The difference between two groups were statistically significant (p=0.000). 3) Cataplexy-positive group, compared to cataplexy-negative group, re-ported more frequent hypnagogic hallucinations (36 subjects, 64.3% vs. 4 subjects, 25.0%) (p=0.005). However, there were no significant differences in frequency or seventy of daytime sleepiness, sleep paralysis and demographic data. 4. In nocturnal polysomnography and MSLT findings, there were no significant differences in all sleep parameters between two groups. Conclusion : Higher frequency of HLA-DQB 1*0602, and lower hypocretin levels in cataplexy-positive groups than Cata-pelxy-negatives suggest that narcoleptics with cataplexy might be a etiologically different disease entity from narcoleptics without cataplexy. Additionally, Current criteria prevail for the diagnosis of narcolepsy need to be reclassified according to the presence of cataplexy or not.
