Recognizing that the ideological nature of Taoist Gwonseonseo whose publication was concentrated during the reign of King Gojong was connected to that of Jeoseungjeon, a Hangul manuscript novel in the 19th century, this study set out to examine the periodic significance of Taoist Gwonseonseo in the 19th century and check the ideological nature of Jeoseungjeon. Taoist Gwonseonseo puts an emphasis on Confucian ethics including loyalty and filial piety in a didactic aspect and shows that the practice of Confucian ethics brings good fortune, which was prominent in many private Taoist books that were huge hits in the latter part of Joseon, when Chinese Taoist Gwonseonseo was introduced in Joseon, translated and circulated in Korean, and spread widely among the public. Those works offer very specific cases of individuals doing good or evil deeds in this world and suffering the consequences in the next world. Jeoseungjeon presents the Buddhist experiences with the next world as the foundation with the next world depicted around the Great Jade Emperor, who emphasizes Confucian ethics, and the hierarchy of Taoist gods under the ultimate the Great Jade Emperor, thus clearly demonstrating the combination pattern of Confucianism, Buddhism, and Taoism in the latter half of Joseon. The work describes the scenes of judgment and punishment in the next world according to the witness of the main character and thus gives specific ideas of daily goods, which is a feature found in the latter half of Joseon different from the previous pattern of next world experiences. It is Taoist Gwonseonseo widely spread among the people those days that connects the link.

The purpose of this study was to develop a program for couples in early stage of marriage for enhancing family resilience based on the concept of 'Family Resilience' by Walsh. Based on the literature review of couples in early stage of marriage, marital enrichment, and Family Resilience, a program focused on belief system, organizational pattern, and communication process was designed and implemented. The program was applied to seven couples in early stage of marriage for four (3hours/session/week) sessions. The Wilcoxon Signed Ranks Test was used to compare the pre and post effects of the program. By operating a focus group composed of the program participants, a qualitative analysis of the participant's evaluation was performed. The pre and post comparative analysis showed a significant enhancement in belief system, organizational pattern, communication process, and dyadic adjustment. The results of the qualitative study in the focus group also reinforced the effectiveness of the program. The evaluation showed that the 3 hour/ 4 session program was appropriate in terms program format. The significances of this study are the concretion of the concept of Family Resilience and providing practice tools for the daily practitioner.

As the limit state design method is applied as a method of designing concrete structures, the ultimate state is considered in the analysis or design. In fact, when the reinforced concrete member bears tensile force, the force is transmitted from the rebar to the concrete, and the structure bears the tensile force to the ultimate state even after yield. Therefore, the accurate evaluation of behavior after yield, it is necessary to study the tension stiffening effect after yield of the flexural member. In this study, a 4-point bending test was conducted on the RC simple beam having a rectangular cross section of the double reinforcement, and the behavior of the member was analyzed in detail using the image analysis method. Using the analysis results, the estimation formula for the tension stiffening effect after yield was proposed, and the applicability of this was verified through the experimental results of existing study. The difference between the ultimate strain and the yield strain representing the ductile behavior of the member is similar to the experimental results. The prediction of the proposed formula is relatively accurate.

In this study, we have investigated microstructure, mechanical properties and wear characteristic of aluminum metal matrix composites with a high volume fraction and uniformly dispersed SiC particles which produced by a liquid pressing process. The volume fraction of bimodal SiC/Al7075 composite was 12% higher than that of the monomodal SiC/Al7075 composite and a compressive strength is increased about 200 MPa. As a result of the abrasion test, the wear width and depth of the bimodal SiC/Al7075 composite were $285.1{\mu}m$ and $0.45{\mu}m$, respectively. The coefficient of friction of bimodal SiC/Al7075 was 0.16.

In this study, the possibility of manufacturing a magnesium (Mg) composites reinforced with continuous silicon carbide (SiC) fibers was examined using a liquid pressing process. We fabricated uniformly dispersed SiC fiberAZ91 composites using a liquid phase pressing process. Furthermore, the precipitates were controlled through heat treatment. As a continuous Mg₂Si phase was formed at the interface between the SiC fiber and the AZ91 matrix alloy, the interfacial bonding strength was improved. The tensile strength at room temperature of the prepared composite was 479 MPa, showing excellent mechanical properties.

In this study, TiC ceramic particulate reinforced steel composites was fabricated using a liquid pressing infiltration process. Studies were conducted on microstructure analysis and basic physical properties such as hardness and corrosion characteristics in salt water environment for comparison with commercial nodular cast iron. As a result of comparison of corrosion characteristics in a salt water environment, both corrosion potential and corrosion current density were lower than that of ductile graphite cast iron. The lower calculated corrosion rate confirms that the TiC-Fe metal composite has superior corrosion resistance than the cast iron.

스텔스 기능성 섬유의 위장은 주간의 경우, 육안 및 망원경 관측에 의해 결정되며 주변자연환경 color matching과 패턴이 핵심 스텔스 요인으로 구성되고, 가시광선 영역 스텔스로 표현할 수 있으며, 군 위장 체계에 있어 기본이 되는 기술 분야로 모든 군 위장제품에 활용되는 필수적인 기술 분야이다. 따라서 가시영역의 위장은 다양한 색상의 위장포와 포의 펀칭 등에 의한 파형특성을 부여하고 주위환경과 특성 조화를 이룸으로써 대상을 위장한다. 주요인자는 색상별 색도, 색차이다. 야간 위장은 근적외선 관측 장비의 탐지에 의해 결정되며 주변자연환경 NIR 반사율과 위장제품의 NIR 반사율 저하/제어기술이 핵심 스텔스 요인으로 구성되고, 근적외선(NIR) 영역 스텔스로 표시할 수 있으며, NIR 스텔스는 대개의 경우 기본적으로 섬유제품이 NIR 영역에서 높은 반사율을 나타내므로 NIR 반사율 저하/제어기술이 핵심이라 할 수 있다. 따라서 근적외선 영역(600~1250nm)의 적외선 반사특성을 산림지역의 반사특성과 조화시켜 위장효과를 부여한다. 위장포에서는 적외선 흡수 색소를 사용하여 적절한 반사특성을 나타나게 해야 한다. 위장용섬유가 detector의 탐지에서 벗어나려면 현재 700~1250nm의 근적외선파장영역에서 주변환경과 유사한 반사율을 지녀야한다. 이에 본 연구에서는 "숲 연구소" 및 서울대학교 "지반공학연구실"의 자문을 받아서 우리나라에서 가장 많이 존재하는 자연환경시료를 선정하여, 선정된 시료의 근적외선영역에서의 반사율을 분석하였다. 자연시료는 산간, 해안, 평야지형으로 각각 구분하여 주변 자연지형에 따른 자연시료의 근적외선영역의 반사율값을 비교하였다. 북한산에서 산간지형의 시료를 채취하였고, 해안지형의 시료는 강화도 동막해수욕장 부근, 평야지형의 시료는 인천 강화도 평야지역에서 채취하여 분석하였다. 비교분석한 지형별 자연시료의 근적외선 반사율값의 데이터베이스구축을 통하여 기존의 위장복과의 비교 적용 및 차후 개선사항 등을 검토하고자 한다.

생명공학기술(biotechnology)은 보건·의료, 농업, 환경, 자원분야에서의 급격한 산업적 응용에 따라 21세기에는 세계경제에 막대한 파급효과를 보일 것으로 예상된다. 경제구조가 점점 고도화되어 한 국가의 기술능력이 산업경쟁력의 확보를 위해 그 중요성이 강조되는 상황에서, 미래첨단기술이라고 할 수 있는 생명공학기술에서의 성공여부는 앞으로 다가올 21세기의 국가 경쟁력 결정에 중요한 열쇠가 될 것이다. 본 연구는 이러한 상황인식하에 생명공학 기술에 대한 일반적인 현황과 전망을 살펴본 뒤 선진국의 생명공학기술 산업화 동향을 진단하고, 우리나라 생명공학산업 현황과 정부의 지원 정책을 조망한 뒤 생명공학산업의 활성화 방안에 대하여 의견을 제시하고 있다. 우리나라의 생명공학기술은 정부의 주도하에 산업계의 연구투자비 및 연구인력의 꾸준한 증대와 아울러 생명공학 제품도 수적으로나 판매규모면에서 큰 증가가 이루어져 왔다. 그러나 본질적으로 우리나라 생명공학기술에 대한 연구는 선진국에 뒤져있기 때문에 기초연구의 역량이 부족하고, 산업계의 과감한 기술개발 투자가 이루어지지 못하였으며, 또한 기술개발과 상업화를 위한 기술하부구조의 구축이 매우 미흡한 실정이다. 또한 WTO체제의 출범에 따른 지적재산권 보호의 압력이 높아지는 상황에서 설상가상으로 IMF체제까지 당하여 기업의 연구개발 능력은 매우 심각한 위기에 봉착하고 있는 것이다. 이러한 상황에서 생명공학산업의 활성화를 위해서는 정부의 역할이 더욱 필요하게 되었다. 본 연구에서는 이러한 상황인식하에 정부의 생명공학산업 활성화를 지원정책으로 연구자금, 시설 등 직접적인 지원정책 중심의 한계적 시각에서 벗어나 기업을 비롯한 기술혁신 주체간 상호작용과 기술혁신 환경조성을 위한 간접적 지원중심의 정책전환 필요성을 제시하고 있다. 또한 우리나라 생명공학 기술혁신시스템을 재정비하기 위한 중점 개선방안으로 연구개발 투자의 확대, 기초연구 역량의 강화, 벤쳐기업형 생명공학기업의 육성, 기술하부구조의 구축, 산업계·학계·연구소간 연계·교류 시스템의 강화를 제시하고 있다.

The study aims to examine how exposure to phonography on the internet affects adolescents' behaviour toward sexual assault and the sex trade industry based on the social learning theory. A nationwide survey was conducted on adolescents between the ages of 14 to 19. Responses from a total of 2,829 adolescents were obtained and utilized in the analysis. The analytic findings showed that Korean adolescents are heavily exposed to phonography on the internet. Students use the internet to search for pornographic web sites, and they periodically look for updated materials. The study showed that between 1.8% to 16.5% of adolescents, who were exposed to or watched pornographic materials, committed sexual assault and were guilty of sexually harassing others. 3.5%(95) of those who were surveyed experienced sex trade. Internet chat rooms are considered to be a contributing factor. The results show that adolescents who were exposed to phonography are more prone to committing the acts of sexual assault and sexual harrassment, and tend to be more influenced toward sexual violence.

This study targets on overall understanding about practitioners' experience at the community addiction management centers on intervening alcoholic-batterers. This research is a qualitative case study based on data that are collected from fifteen practitioners' interview experiences of both focus group and individual and data from supervising, advising, and workshop attending. As a result, the research shows that 'Overwhelmed to deal with alcoholic-batterers', 'Strengthening ability through pre-performances', 'Making an effort continuously to solve problems' and 'Unwillingness changes by intervening alcoholic-batterers' on upper categories of practitioners' experiences. Under alternative solutions and practical categories, it shows that 'Gaps between the needs and the reality' and 'Concrete needs to achieve competence'. To provide effective strategies, the study suggests practical and political implications that are reflected specific environments of the community addiction management centers.
