Most of protecting security activity is carried out by manpower partly by security equipment. The protecting security market and the area of protecting security activity is increasing in spite of change of economic and social environment situation. For more effective protecting security activity, the coordination of electronic equipment and manpower is required. So some application method is suggested throughout the thesis, which is especially focused on new approaching method. The integration of intrusion detecting system, C.C.TV system and Access control system is introduced for general application in chapter III, and some application systems are proposed for protecting security activity in chapter IV. But the security equipment is only aid for manpower, so manpower and equipment should be coordinated well.

This study based on the laboratory works, analyzes factors affecting local scour in order to understand various characteristics of the local scour surrounding bridge piers. Attached with scour protection device as a method for decreasing local scour, it carries out the laboratory experiments and calculates the scour depth. From the experiments attached with the scour protection devices, it seems possible to reduce the scour depth as the protecting plate, column and sacrificial piles are built in the same height with flume bed at pier or footing upstream interrupted falling-flow. And then it could reduce scour depth. The paper presents the following research results: First, the decreasing degree of scour depth is in order of protecting column, protecting plate, sacrificial piles and non-protecting facilities. However, it shows no meaningful difference between protecting column and protecting plate. Second, when $L_p/b$=0.5~1, the decreasing effect of scour depth reached the maximum of 40 percents.

A new method of protecting 3-phase squirrel-cage induction motor aginst burning-out by unbalance operation is proposed. This paper studied various kinds of situations occurred by unbalance operating in 3-phase induction motor, and we provided the search coils in the slots of stator and rotor for the purpose of detecting electrical phenpmena during unbalance operation. Through experiments, we find that search coils in the slots of stator is effective method for protecting the induction motor from unbalance operating.

The influence of protecting groups on the β-sheet-structure-stability of protected peptides was studied in organic solvents. α-amino groups, carboxyl groups and side chain functional groups of model peptides were protected by suitable groups commonly used in peptide synthesis. The difference of the solubilities of model peptides was investigated by the solvent-titration method by using IR absorption spectra. The β-sheet structure of model peptide in CH2Cl2 was easily disrupted by increasing the amounts of DMSO. The β-sheet-structure-stabilizing potentials of each protecting group showed similar behaviors except Npys, Mts and Z2. The result exhibits that the < SPβ > values of protected peptides are almost independent of the kinds of their protecting groups.

Ion induced secondary electron emission coefficients γ of protecting layers of an AC plasma display panel(AC-PDP) have been measured. In order to solve the surface charging effect during the measurement at insulating samples like MgO, a new method with the patterned gold line charge neutralization has been introduced. The measurement was performed at the samples, MgO and MgO+MgF$_2$, which showed a great difference in the firing voltage between the two protecting layers. The γ value has been compared with the firing voltage Vf of the AC-PDP with the same protecting layer. Correct relationship between γ and Vf has been observed. Thus, the patterned gold line method has been proven to be successful for the measurement of the secondary electron emission yield at insulator sample surfaces.

실리카퓸, 플라이애쉬, 고로슬래등 미분말 혼화재가 포함된 고성능 콘크리트(High Performance Concrete) 교량 바닥판 보호공법은 1980년 초부터 북미를 중심으로 사용되어 왔다. 본 보고서에서는 교량 바닥판 보호를 위한 고성능 콘크리트 적용사례와 고성능 콘크리트를 이용한 두 가지 공법(고성능 콘크리트 교면포장공법, 노출 바닥판 공법)에 대해 소개한다. 위 두 공법은 이미 북미에서 많은 실적을 보유하고 있으며 특히, 실리카퓸과 PVA섬유가 포함된 고성능 콘크리트 교면포장공법은 국내에서도 성공적으로 적용되고 있다. 따라서 본고에서는 기존 아스팔트 재료를 대체할 수 있고, 최근 국내에서도 그 적용성에 대한 관심과 실 시공이 이루어지고 있는 고성능 콘크리트를 이용한 교면포장 (Overlay) 공법 및 노출 바닥판(Full depth) 공법에 대해 소개하고자 한다.

중원 미륵리사지 입상석불 보호석실을 이루고 있는 암석은 주로 석영, 퍼어사이트, 사장석 및 흑운모로 이루어져 있는 백악기의 화강암이다. 이들 암석에는 매우 많은 균열들이 발달되어 있는데 이들은 성인적으로 볼 때 양파껍질구조를 따라 진행된 박리작용, 1차적인 그리고 압력에 의한 것으로 구분할 수 있다. 압력에 의한 것들은 보호석실의 구조적 불균형에 의한 힘의 편중에 의해 생성된 것으로 생각되며 박리작용에 의한 것에 중첩되어 발달하는 것이 보통이다. 구조적 불균형은 심한 풍화에 따른 암석의 물성의 변화, 보호석실의 부분적인 하중의 차이에 따른 토양의 차등침하, 서측면 아래의 토양기반의 서쪽으로의 포행과 이에 수반된 토양기반의 지지율의 부분적인 차이, 그리고 서측면 아래의 토양기반의 서쪽으로의 포행과 이에 수반된 토양기반의 지지율의 부분적인 차이, 그리고 서측면 석축의 토양 속으로의 부분적인 침하 등에 기인하는 것으로 생각된다. 보호 석실의 보전을 위해서는 이러한 구조적 불균형을 야기시킨 토양기반을 안정시키는 방법과 균열들을 처리하는 방안이 우선적으로 강구되어야 할 것으로 생각된다.

Purpose: The purpose of this study was to investigate the patient's perception of the nurse's behavior in protecting patient privacy and to make suggestions for medical facilities to increase protection of patient privacy. Method: The research was a survey study The data on protection of privacy in primary nursing, for physical privacy, of patient information and in private conversations were collected in October 2005 from 187 patients in a university hospital. Frequencies, means, t-test, ANOVA, and $x^2$-test were used to analyze the data. The SPSS 13.0 for Windows program was used. Results: The mean score for patients' perception of nurse protection of their privacy was 3.33. There were significant differences in perception of protecting patients' privacy according to gender for private conversation, according to level of education for all but physical nursing and for number of admissions for total score and for primary nursing. Conclusion: The results of this study suggest the following: a) Institutional polices and nursing guideline should be clearly stated as to the nurses' duty to protect patient privacy. b) Medical facilities should be arranged in a way that allows for the protection of patients' medical information, and should focus on patient privacy. c) It is necessary of nurses to receive periodic in-service education on protecting patient privacy.

Biometrics systems are used in a wide range of areas, including the area of crime prevention, due to their unique characteristics. However, serious problems can occur if biometric information is disclosed to an unauthorized user. To address these issues, this paper proposes a real valued fuzzy vault method, which adopts a real number error correction code to implement a fuzzy vault scheme for protecting fingerprint temples. The proposed method provides the benefit of allowing the private key value to be changed at any time, unlike biometric template such as a fingerprint, which is not easily renewable even if its security has been breached. The validity of the proposed method is verified for fingerprint verification.
