We compared the texts of the two types of military books, 『Mubiji』 and 『Yungsalyujeom (戎事類占)』. In this research, it is proved that Lee-Jema transcribed a segment on martial mantic in 『Mubiji (武備志)』 which is a book on military studies and named it 「Jipungjo (知風兆)」 since he had practical interest in military affairs. Lee-Jema had been serving as a military officer when his peculiar thought was beginning to unfold and maintained his interest in military affairs until his latter years. It is necessary to take a military studies based approach to comprehend Lee-Jema's thought since military affairs had great influence on his life.

The objectives of this study was to explore the concept, the origin and history, and classification of amenity. Amenity is a new approach about nature, environment and the world. The concept, origin and classification of amenity was widely diversified, however, the concept of amenity was inclusive and abstract, so amenity was easier to recognize than to define. Even though many people were interested in amenity, however, the movement or practice of amenity in Korea was still in infancy stage. This paper was an exploratory study of amenity and more detailed further studies on amenity should conducted in Korea. It was suggested that we should not start on philosophical question of amenity. We should rather start on practical problems of how to put into practice to insure quality of life in the community, to conserve nature, to study practical dimensions of amenity, and to develop indicators to measure amenity.

The natural history of the anterior cruciate ligament(ACL)-deficient knee remains controversial. although numerous investigation have tried to ascertain the course that the knee would follow once the ACL has lost functional integrity. An extensive review of the literature performed according to symptoms. physical examinations, associated surrounding tissue injuries. returns to activity level and radiological changes in the knee joint. An active individual with a non-functioning ACL was susceptible to injury to the menisci and deteriorate the articular cartilage, followed radiographic changes. An activity levels in general also changed after injury. The most common symptom was pain. But instability varied in these individuals. Conclusively we believe that all these factors will eventually, if not initially, result in a symptomatic knee. which will result in significant limitations to the individual's desired level. So we recommend an aggressive approach in person who desired to return to a relatively active life style in young person as well as in middle aged individuals who have significant symptomatic ACL deficient knee.

This research focuses on the life history of university professor and the meaning of their lives to provide career information to parents and teachers conducting childhood career education. professor K with 25 years of professorship was targeted for insides's view(emic), which describes the life story through the professor's voice and words, was used as the method of research and additional data was collected through in-depth interviews with professor K, his writings, e-mails and in-depth interviews. The collected data was electronically transferred and categorized for field and categorical analysis. The analysis showed that the motive for professor K to enter academic society was due to his utmost efforts, assistance of family, and his friend encountering. Also after entering the university, he served as key role in research, education and as an appointed professor. After retirement, he is contributing to the society as a expert and practitioner. As such, 'continuous effort and consistent personal innovation', 'strong belief and clear calling', 'warm humanity and practical life', and 'flexible attitude and educational passion' were deducted from professor K 's professional capability.

The purpose of this study is a exploratory study for understanding the process of the social isolation of the socially isolated elderly through the approach to their life history. The research was analyzed by one of the methods of qualitative research on life history, the conceptual framework of 'Dimensions, turning, and adaptation' of Mandelbaum(1973). According to the results of this study, the socially isolated elderly people were found to be socially isolated by experiencing complex difficulties such as family disconnection, poverty, poor job and health deterioration. Specifically, in the area of life, there was experience of poor relationship with parent, absence of family, poverty of family and unfavorable relationship with surrounding people in life with original family before isolation. They had bad jobs in the labor market, such as hard labor, delivery, business, and chores. In the area of turning point, we experienced family break due to the separation of the original family and the spouse due to various reasons such as financial crisis, parental divorce and death, spouse affair, economic difficulty. In a transitional stage in the life, many reasons such as the financial crisis, the death of parents, the extramarital affair and economic difficulties led to the disconnection from their original family and their spouses. In an adaptive phase, participants accepted the changed life at each turning point in their lives, carrying out their roles, compromising and trying to adapt properly. He said that their current life, which has entered the social safety net system of the people's basic recipients, has led him to live a more stable life and is adapting to personal hobbies and vicarious satisfaction through networks. This result is somewhat different from previous studies in which isolated elderly people were severely exposed to the risk of depression and loneliness. However, we should also consider the characteristics of this study that interviewed elderly people with relatively low isolation. Based on the results of this research, he presented various practical policy implications.

The exhaust system of automobile is faced with random or spectrum types of fatigue loads during usage life and so needs to be closely estimated for quality and performance to have enough certainty on design endurance lift during preliminary design process. Structural operation conditions, operation load history, property of material and manufacturing process etc. should be considered by performing experiment approach. Using the software program for predicting fatigue life quickly and exactly in preliminary design stage saves plenty of time and cost generated by fatigue tests. In this paper, fatigue life prediction was performed on the basis of fatigue analysis using MSC/FATIGUE and load data from field test and the life of development items was estimated and compared through the results.

This qualitative study explored a middle-aged lesbian's life and her identities by the oral life history approach in feminist epistemology, where the participant is not the object but the subject of knowledge. The participant kept her own perspective that her homosexuality was not intrinsic but constructed. In her life's history, she was a "docile body" accepting socially constructed historical meaning of homosexuality, as well as a "resistant body" protesting against social discrimination and oppression for homosexual population. She overcame an embedded negative recognition of her scaled injured body and her sexuality as "deficient". Finally, she showed an amazing resilience and an indomitable spirit for reconstructing the meaning of her body as "blessed." Beyond the deficient body, as an active agent not the pathologic sexual minority, she could cultivate compassion and empathy for others. From the results, it is important how to place gender and sexuality in the context of social work theory and practice. Sexuality, not sexual orientation, is 'our' collective agenda to address the social problems which were associated with social hierarchy, inequality, and injustice.

Oral history research is carried out through collecting information about a living person. The data collected from an oral history project is not a mere fact or a mass of information but accounts of persons who reveal their own personalities. For this reason, oral history research and data collection and the use of such data must be based on rigorous ethical standards. The Bioethics and Safety Law shares a similar view on human subject research, and the Institutional Review Boards includes human subject research as a subject of review and management. However, the Bioethics and Safety Law's protection of personalities and human rights focuses on life sciences methodologies, which are not suitable for qualitative research, such as an oral history of a value oriented and critical approach to human beings. This study examines the details of the Bioethics and Safety Law related to human subject research and the problems that may arise when this law is applied to subjects in humanities and social sciences such as oral history. Through this study, alternative methodologies, which can be used for oral history research, while maintaining academic autonomy, are suggested.

Water distribution networks (WDNs) are designed to satisfy water requirement of an urban community. One of the central issues in human history is providing sufficient quality and quantity of water through WDNs. A WDN consists of a great number of pipelines with different ages, lengths, materials, and sizes in varying degrees of deterioration. The available annual budget for rehabilitation of these infrastructures only covers part of the network; thus it is important to manage the limited budget in the most cost-effective manner. In this study, a novel pipe replacement scheduling approach is proposed in order to smooth the annual investment time series based on a life cycle cost assessment. The proposed approach is applied to a real WDN currently operating in South Korea. The proposed scheduling plan considers both the annual budget limitation and the optimum investment on pipes' useful life. A non-dominated sorting genetic algorithm is used to solve a multi-objective optimization problem. Three decision-making objectives, including the minimum imposed LCC of the network, the minimum standard deviation of annual cost, and the minimum average age of the network, are considered to find optimal pipe replacement planning over long-term time period. The results indicate that the proposed scheduling structure provides efficient and cost-effective rehabilitation management of water network with consistent annual budget.
