Purpose: The purpose of this study is to provide basic data for the improvement of the quality in the emergency nursing services by investigating the expectation level and actual received level with nursing care and identifying the factors that influence patient satisfaction with the emergency nursing care in the military hospitals. Method: Using a self report questionnaire, data were collected from 150 patients who had been admitted in military hospitals emergency department. The data collection was done between April 17 and April 30, 2006. At least, 145 questionnaires were analyzed and used in this study. Results: The average sum score was 61.93 out of 76 with standard deviation 9.590. The mean of the patient's expectation levels with the overall emergency nursing services was $(3.25{\pm}.504)$ out of the highest score 4. the average sum score was 63.27 out of 76 with standard deviation 9.902. The mean score of the patient's actual levels with the overall emergency nursing services was $(3.33{\pm}.521)$ out of the highest score 4. Conclusion: nursing management strategies must be established to remove patient's dissatisfaction factors and to improve the emergency nursing care quality through continuous measurement and assessment of the patient's satisfaction with emergency nursing services in military hospitals.

To prevent surface and underground water pollution, wastewater treatment is essential. Four bench-scale activated sludge units (10 L operational volumes) were operated at 5, 10 and $20^{\circ}C$ for evaluation of treatment efficiencies with typical wastewater from swine housing. The units were set for a 24-hour cycle. As compared to the conventional process, high removal efficiencies for organic substances, nitrogen and phosphorus in swine wastewater were obtained simultaneously with an intermittent aeration process (lAP). The NOx-N produced during an aeration period was immediately reduced to nitrogen gas (e.g. $N_2$ or $N_2O$) in the subsequent non-aeration periods, and nitrification in aeration periods occurred smoothly. Under these conditions, phosphorus removal occurred with the release of phosphorus during the non-aeration periods followed by the excess uptake of phosphorus in the activated sludge during aeration periods. It was confirmed that the lAP had a better ability to remove pollutants under both low temperatures and high nitrogen loading conditions than the ordinary method did. In addition to that, the total emission of $N_2O$ from lAP was reduced to approximately 1/50 of the conventional process for the same loading. By adopting an adequate aeration programme for individual swine wastewater treatment, this system will provide a promising means for nitrogen and phosphorus control without pH control or addition of methanol.

본 논문에서는 현재 우리나라의 상황에서 경쟁체제에 적합한 효과적인 전화요금정책을 외국의 사례로부터 도출해 보았다. 특히 비대칭 요금규제 정책의 목표가 신구 사업자의 시장점유율에 있다고 보았을 때, 주어진 목표의 달성을 위해 지배적 사업자와 신규 사업자간의 요금격차가 어느 수준이어야 하는가를 경험적 분석을 통해 알아보았다. 시뮬레이션 결과는 우리나라의 통신산업 구조하에서 빠른 시일 내에 지배적 사업자가 존재하지 않는 시장구조가 되기 위해서는 급속한 전화서비스 수요의 증가가 이루어져야 함을 보였다. 또한 경쟁확립을 위해서는 지배적 사업자인 한국통신을 시급히 민영화하여야 하고 이와 더불어 시내전화 사업과 시외전화 사업을 회계분리 하여야 한다.

Cost estimates are necessary for government acquisition program to support decisions about funding, to develop annual budget requests and to validate resource requirements at key decision points. Many researches have been done about cost estimating technique recently. Parametric cost estimating models based on CERs(Cost Estimating Relationships) have been mainly used using regression method with historical data. However, there are many restrictions in developing Korean version CERs because the number of data points are too small. Specially, data collection and data management system are unstable in Korean defense environment, when developing CERs. In this research, we analyzed the historical data, and found some cost drivers in guided weapon system area. We developed the Acquisition Unit Cost CER using the regression to remove multicollinearity in the historical data. So we could overcome the restriction of the insufficient sample number. This research as a first attempt is meaningful in terms of obtaining our own Acquisition Unit Cost CER using historical cost and physical characteristic in Korean development environment.

전기분해 공정으로 제조한 전해산성수를 이용하여 생활 악취의 원인인 암모니아를 제거하는 방법을 연구하였다. 제조한 전해산성수는 pH와 ORP 변화 측정을 통해 안정적으로 알칼리성 암모니아를 중화 시킬 수 있는 전해수(중화제)로 확인되었다. 자외-가시선 흡광도 분석과 전기화학적 개방회로 전위 측정으로 전해산성수와 암모니아수를 혼합한 용액에서 암모니아가 제거되는 것을 확인하였다. 암모니아 가스 발생량 측정을 통해 전해산성수가 암모니아를 중화시켜 악취 발생시키는 암모니아가 효과적으로 제거되는 것으로 조사되었다. 친환경적인 전해산성수가 악취의 원인 물질인 암모니아를 효과적으로 안전하게 제거할 수 있는 것으로 확인되었다.

Thyroglossal duct cyst is ectodermal remnant, which may develop along the line of descent of the thyroid gland from the foramen cecum of the tongue to the pyramidal lobe of the thyroid gland. Meticulous dissection of the cyst and duct, along with the body of the hyoid bone is necessary to avoid recurrence. Eighty-one patients with thyroglossal duct cyst treated at Hanyang University Hospital between January 1980 and December 2000 were reviewed to determine the incidence and to analyze the result of management. The male-to-female ratio was 1.4:1(47:34) with a male preponderance. They are most commonly present at 3-8years(54.2 %) of age, but rarely present at infancy. The most common symptom was a painless midline neck mass(76.5 %, 62cases). Eighty-one patients underwent modified Sistrunk operation without evidence of recurrence. Eight-nine percent(72 cases) of these lesions were located between thyroid substance and hyoid bone, and 11 %(9 cases) were above the hyoid bone. There were 22 infected cysts(27.2 %). The Sistrunk operation is a gold standard for treating the thyroglossal duct cysts. For best results in thyroglossal duct cyst surgery, one should make every effort to remove the cyst intact in continuity with the body of the hyoid bone. In our institute, Sistrunk operation modified by the authors showed a good result.

Undoubtedly, the basic sinking fund formula gives the future value of a series of equal installments. The main underlying assumption for using this formula is that installment and compounding frequency must be in equal interval. But when installment for a deposit scheme or any other savings scheme and compounding frequency do not occur in an equal interval, which is treated as the complex annuity problems in Finance Literature, the basic sinking fund formula does not give the accurate result. As a result, the obtainable amount from different deposit schemes offered by different banks and financial institutions does not match with the amount of future value calculated through the basic sinking fund formula by the investors or savers. This study focuses the concealed facts for such type of mismatches in values and at the same time it provides a solution through developing a new formula by extending the basic formula intended not only to remove those mismatches but also get the accurate future value from a sinking fund provision in case of complex annuity. Besides, since banks and financial institutions calculate the interest on the average amount of equal installments deposited within a period of time due to complex annuity, the study also formulates an arithmetic formula for calculating the average amount of installment.

해킹과 같은 사이버 공격의 약 75%가 애플리케이션의 보안 취약점을 악용하기 때문에 안전행정부에서는 코딩 단계에서부터 사이버 공격을 막을 수 있고 보안취약점을 제거할 수 있는 시큐어 코딩 가이드를 제공하고 있다. 본 논문에서는 안행부가 제시한 시큐어 코딩 가이드 7개의 항목들에 대해 AHP기법을 사용하여 우선순위를 찾고 중요도 분석을 하였다. 그 결과 '에러 처리'가 가장 중요한 항목으로 결정되었다. 현재 소프트웨어 감리에 시큐어 코딩에 관한 항목이 없는데, 이 분석 결과는 소프트웨어 개발 과정 중 감리 기준으로 유용하게 사용될 것이다.
