The global pattern of growth-dependent gene expression in Streptococcus pneumoniae strains was evaluated using a high-density DNA microarray. Total RNAs obtained from an avirulent S. pneumoniae strain R6 and a virulent strain AMC96-6 were used to compare the expression patterns at seven time points (2.5, 3.5, 4.5, 5.5, 6.0, 6.5, and 8.0 h). The expression profile of strain R6 changed between log and stationary growth (the Log-Stat switch). There were clear differences between the growth-dependent gene expression profiles of the virulent and avirulent pneumococcal strains in 367 of 1,112 genes. Transcripts of genes associated with bacterial competence and capsular polysaccharide formation, as well as clpP and cbpA, were higher in the virulent strain. Our data suggest that late log or early stationary phase may be the most virulent phase of S. pneumoniae.

With the rapid development of information and communication technology, a lot of multi-media learning programs are being developed and reported in the field of Emergency medicine both home and abroad. In this connection, this study was aimed at developing a foreign-body airway obstruction courseware in adults for EMT. The development period of CAI courseware lasted from May 2003 through November 2003. Among CAI courseware patterns, private instruction and repeat practice and simulation patterns were used as an instruction-learning strategy. The learning contents of the CAI courseware consisted of five chapters concerning (1) A relief of partial FBAO in the responsible victim, (2) A relief of complete FBAO in the responsible victim, (3) In case of unconsciousness in the responsible victim without removing all foreign body, (4) In case of consciousness in all victims after getting removed all foreign body and (5) A complete airway obstruction in victims without consciousness on the basis of assess responsiveness and the degree of airway obstruction. The way to use this courseware, with just a click on one specific chapter, was developed to proceed a course with progressive algorithm, a method of solving problems by choosing one between two situations. A characteristic of this CAI courseware is the enhanced efficiency of an instruction-learning method by providing an opportunity of choice based on situations in its effort to encourage learners to use a self-initiated learning method, not one-way method and to enhance problem solving skills among situations. Moreover, this courseware went through the diverse phases such as development, application, feedback in connection with learning process by practicing teachers, so that the courseware could be used frequently in the future. The contents of this courseware were written with the web, so that, if necessary, the contents could be continuously modified and complemented and handed out in the form of CD-ROM. This study indicates that the development of a variety of CAI courseware requires institutional and financial assistance and initiatives reflecting a reality in terms of learning process, technical assistance and resources.

Meningococcal Disease, manifesting as meningitis and septicemia, is a life-threatening bacterial infection that results in significant morbidity and mortality, particularly in childhood. Its epidemic potential and limited opportunities for clinical intervention due to its rapid course present unique public health and clinical challenges. Incidence is highest in infants and young children, with a secondary peak of risk in adolescents. Approximately 10% of cases are fatal and survivors can be left with serious and permanent sequelae including amputations, hearing loss and cognitive impairment. Transmission is only from human-to-human, by infected respiratory tract secretions or saliva and therefore crowding poses a tremendously elevated risk for disease development. Military recruits and university students are at high risk due to the high carriage rate in adolescents, their behavior patterns and close contact. Menveo$^{(R)}$ (Novartis Vaccines and Diagnostics), a novel quadrivalent meningococcal conjugate vaccine directed against meningococcal serogroups A, C, W-135 and Y, has been shown to be immunogenic and well tolerated in all age groups and was recently licensed for use in Korea. Recent cases and deaths among military recruits drew public attention to their elevated risk and the Korean government has recommended vaccination of all new military recruits. Many Korean students seek to attend school, university, or language institutes in countries where routine meningococcal vaccination is required - clinicians should be aware of such requirements to ensure that students are vaccinated prior to arrival in the destination country.

This study has examined multiple influences of several variables on parenting behavior by looking into illustrative studies. This study provides support to the view that various factors influence parenting and that parenting behavior is multiply determined. Characteristics of parents, children and the context in which parent-child relations occur cause different childrearing patterns among parents. This study can be summarized as follows: 1) Parental behavior is influenced to a large degree by what the parent brings to the situation. In other words, characteristics of the parent including personality characteristics, interpersonal skills, problem-solving skills, level of maturity, values and childrearing beliefs contribute to individual differences in parenting. 2) The parent's relationship history influences the personality characteristics that the parent brings to his or her adult roles. To understand who the parent is today, we have to look at who the parent was, and what the parent was doing in the years prior to parenthood. That is, we need to see the life course of the individual before parenthood. 3) Contextual variables including the immediate context and the larger context have proved to influence parental behaviors. Characteristics of the immediate context such as the quality of marital rationship can influence the parent's psychological well-being and his or her behavior toward the childen while characteristics of the larger context such as the economic situation and the neighborhood can influence the level of stress experienced by the parent and cosequently how the parent relates to his or her child. 4) In order to understand the development of the parent-child relationship we need to look at the characteristics of the child. Children may elicit positive behaviors from their parents, or they may possess characteristics that the parents find aversive thus leading to difficulties in the relationship. Therefore, much depends on the fit beween the characteristics of the parents and characteristics of the child. By examining multiple contemporaneous influences on parenting, this study could deepen the understanding of why parents have different childrearing patterns, why some parents fail to meet their children's demands and why parents act in certain ways. What we ultimately hope is that as we learn more about parenting and the development of parent-child relationships, we will be better able to provide parents with the supports they need to achieve their parenting goals.

The purpose of this study was to investigate the disposition of adolescents in their ornament wearing pattern associate with their life style and clothing behavior. The subject of this study consists of 345 middle and high school girls living in Chung-Nam Province and Taejon Metropolitan City. SPSS/PC+ program was utilized to calculated frequency(N), mean value(M) and standard deviation(SD) for statistical analysis. Differences among the populations were examined through f test, ANOVA. The results of this study reveals that the ornaments wearing patterns are significantly different according to their life style and clothing behavior as follows: 1. Correlation between the wear of ornaments and the life style: School girls who pursue the modernistic life style prefer the fashionable ornaments (e.g. sunglasses) and they are always in contact with the latest information. On the contrary, school girls who pursue the practical life style emphasize on the practical use when they purchase the ornaments, e.g. umbrella. School girls having romantic or passive nature have a preference for the brand name and brand image of the ornaments and they in general would like to buy ornaments such as the bracelets. 2. Correlation between the wear of ornaments and the clothing behavior: School girls having sympathetic nature and being deeply interested in clothing put a stress on the latest fashion of the ornaments. They usually want to buy fashionable ornaments such as the cellular phone, beeper and sunglasses. Subjects who estimate themselves by their garments are sensitive to the price of the ornaments while aesthetes emphasize the brand image of the ornaments. Chaste school girls put their emphasis on the quality of the ornaments and they most want to have functional hair bands. Following suggestions can be made based on the discussions above: It is necessary for us to have correct understanding about the correlation between the ornaments and clothing of school girls in order to lead them to have appropriate clothing behavior. Furthermore, it is required to construct a bridge linking a course of study to rational habits guidance which will provide us more appropriate tools for clothing behavior guidance.

Korean economy has been developed successfully in the course of implementing the five year economic development plans since 1962. The gap of incomes and quality of life between rural and urban area has been widened and it made rural farm laborers drain to urban areas. Therefore the prevailing situation of labor shortage and wage hike in rural area has made farm management deteriorate in recent years. Under the internal and international unfavorable economic conditions, marginal farm land of 66.5 thousand ha has been idled as of end of 1993. The total area outside agricultural development zone with bad farming conditions including irrigation and drainage, and land consolidation for mechanization were estimated at 360.4thousand ha equivalent to 17.5% of the total farm land area in Korea. Considering the topographical conditions of marginal lands, the effective use of marginal lands should be studied from the view point of public interest rather than from the view point of individual economic conditions. Considering the present agricultural economic settings, such as price decrease, unfavourable benefits of farm products, labour shrotage, free trade of farm products and poor physical condition of marginal lands, the institutional and realistical measures for the effective utilization of idle and marginal land should be studied as soon as possible. Detail land use pattern should be surveyed in the areas outside agricultural development zone and have to be classified as orchard farms, grass land, fish culture farms, lawn and ornamental tree farm, sight seeing and leisure farms for urban peoples, special crops production farms and common farms to be developed for farm mechanization. According to the surveyed results, the expected utilization patterns of the idle and marginal lands could be considerd as village common use, farm land base development, leisure farm development, mutual complementary utilization between urban and rural areas, G't purchase and management, credit supply and new extension services, improvement of cropping patterns and sight seeing and leisure farm patterns. For the successful and reasonable management of the marginal lands, the actions such as institutional improvement, prohibition of idle marginal land, enforcement of activities of farm management committee members and land banking system of RDC including development and utilization systems should be included.

This study is basically about the changing appearance of the big pavilion, Yeongnamnu in Miryang city belonging to the government guesthouse of Joseon dynasty. And the purpose of this study confirms that even if the appearance of the building has not changed, the function of the building changes because the reason why people think about the building is also different. First, looked at the appearance of architecture and the function of architecture that changes with the times. In the course of the research, the changes of pavilion were traced by dividing it into five from Kory? dynasty which was first established to the present. Then, tried to find out the change patterns by analyzing important events related to buildings or places in each period. As a result, the following facts were confirmed. 1. Because of the Buddhist repression policy in Joseon Dynasty, the Yeongnamnu changed from the temple pavilion to the government pavilion. 2. Throughout the Joseon Dynasty, Yeongnamnu was the representative scenic of Miryang City. 3. In the late Joseon Dynasty, Yeongnamnu was famous as a place where a woman named Arang devoted her life in order to preserve his fidelity. 4. Since 1910, Yeongnamnu has become an important cultural asset, and space has been widely used as a venue for various public events. 5. From 1945 to 1999, Yeongnamnu was used mainly for the events of Arang Remembrance and Miryang Culture Festival. And the inner space of Yeongnamnu was rarely used because people thought preservation is important.

To the human being, the space as the objective for fundamental thought called 'Being', and the space as the place for actual experience containing 'Life and Experience', have coexisted. Such dual characteristics owned by the space have come to the present creating various spatial viewpoints. As for the space as the objective for various thoughts and interpretations, its emphasis is nowadays being moved to the existence from such being. There is the event in the core of such change. Human's recognition for the space is originated from the observed events, which appears as an immense meaning, as it 'is accumulated as the experience. Therefore, the importance of the event in another viewpoint thinking the space is becoming bigger. This research has tried to grasp the tendency for the place-orientation by grasping the meaning owned by the event through the course that the viewpoint for such space has been changed. This research put its focus on clarifying the relationship between the place and event that are brought into relief by tracking down the transitional process of the viewpoint of space in the history of Occidental philosophy. Through this process, this research came to have a grip on the relationship in which a sense of place obviously stands out in bold relief as a result of an event, an emblem of an event, condition of an event, and as an event itself. Such four patterns are not mutually individual phenomenon, but form a discourse on modern space by traversing each other crisscross.
