Lateral gene transfer (LGT) of genes from other bacteria into Vibrio cholerae is expectable because of the pronounced natural competence of the bacterium. In this study, quantitative aspects of LGT among the three species of Vibrio pathogenic to humans were characterized. Genome sequences of V. cholerae N16961, V. parahaemolyticus RIMD2210633, V. vulnificus CMCP6, and Escherichia coli K12 substrain MG1655 were analyzed to determine orthologous quartets of protein coding genes present in all four genomes. Phylogenetic analyses on the quartets were conducted to resolve vertical versus lateral patterns of gene polymorphisms based on congruence versus incongruence of phylogenetic trees. About 70% of the quartets could be resolved as either cohesive topology (75%) or LGT tree topologies (25%). The amount of LGT genes in Vibrio spp. appeared to be abnormally high for a genus and comparable to those of families. Patched distributions of LGT from different donors were observed on a chromosome. In the small chromosome of V. cholerae, physical linkages among LGT loci spanned half the length of the chromosome. Either accumulative selection for the donor alleles in LGT or presence of large-scale LGT events was hypothesized. These findings warrant further studies on the nature of donor-specificity of LGT alleles and its influence on evolution of Vibrio virulence to humans.

The efficient strategies to cope with unpredictable and/or harmful environmental changes have been developed by every organism in order to ensure its survival and continuity of it's own species. As a results, all living things on earth maintain dynamically internal stability via a process termed 'homeostasis' among physiological parameters despite of external environment changes. Stress is an emotional and physical response to threat homeostasis. Stress may have not only transient but rather permanent effect on the organism; recent evidence clearly show that prenatal stress could organize or imprint permanently physiological systems without any change in genetic codes, a process known as 'epigenetic programming'. In this review, a series of reproduction-associated events occurred in prenatally stressed male rats such as alteration in the structure of sexually dimorphic brain regions, modification of neurotransmitter metabolism, changes in reproductive endocrine status, and finally, disorders of sexual behavior will be introduced. The fetal brain is highly sensitive to prenatal programming and glucocorticoids in particular have powerful brain-programming properties. The chronic hyperactivation of fetal brain by maternal stress-induced glucocorticoid input will provide new program via increasing the neuroplasticities. This 'increased neuroplasticities' will be the basis for the 'increased phenotypic plasticities' rendering the organism's better adaptation to environmental challenges. In conclusion, organism who experienced 'harsh' environment in his fetal life seems to give up a certain portion of reproductive competence to make good chance of survival in his future life by epigenetic (re)programming.

Objectives: The aim of this study was to investigate the quality of life of caretaking family members who have a patient with psychiatric disorders. The results will be served as a basic data of ameliorating the quality of life of caregivers. Methods: 78 caretaking family members who have a patient with schizophrenia and 54 caretaking family members who have a patient with alcohol dependence, a total of 132 persons completed the questionnaire, and analyzed. The Korean version of the SmithKline Beecham Quality of Life Scale and the Family Burden Scale were applied. Results: There was no statistically significant correlation between burden and sex, age, income, and duration of living with patients before onset. The male caregiver showed higher quality of life than that of female. It showed statistically significant correlation between age and factor physical well-being and factor activity. 41% of variance of quality of life of caregivers were explained by the stress response, burden, and overall merits of the field of psychiatry, and the tension had the most explanatory power. Conclusion: The chronic illness may give a burden on caregivers, and that decrease the quality of life of caregivers. The longer duration of illness of patients, the lower quality of life of caregivers on competence factor. Therefore, the authors recommend the therapeutic modality must be offered to the caregivers who may experience the stress and burden.

The major purpose of this study is to scrutinize and analyze various factors in numerous aspects of two different library systems for the visually handicapped, namely braille library and a special section for the visually handicapped in the public library system. The analyses may provide theoretical and conceptual framework on which strategies to enhance services for the visually handicapped is to be developed. More specifically, this study seeks (1) to examine a linkage between the degree of maintenance of staffs, collections, and equipment and the level of satisfactions of librarians and (2) to come up with more effective mechanisms of welfare services for the visually handicapped in each library system. This research is qualitative-descriptive and uses interview method. Fourteen libraries throughout the nation (4 public libraries with a reading room for the visually handicapped and 8 braille libraries) which had been in operation more than one year were selected as subjects for the research. Findings and results of the analyses are summarized as follows : 1. There seems to be general consensus that each of public and braille library has significant but, to a certain extent, different roles to play in order to enhance library services for the visually handicapped. Recruitment of qualified librarians, increase of the volume of collection, and enlargement of reading room space are noted as immediate concerns for the former. For the latter, it was suggested that increase of the number of staff for publishing, securing more equipments for pulication in braille, and wider scope as well as more variety of publications are the pressing problems at hand. 2. Both public and braille library employ one librarian for the visually handicapped who is required to have educational background in library science and special education. In addition, one must have competence in reading braille types. 3. Majority of reading rooms in those libraries is so small in physical aspect that size and number of seats are 66m2 and 15 seats respectively because circulation services are mainly in use due to the problem of inaccessibility which is commonly suffered by the visually handicapped. 4. Library services for the visually handicapped are heavily concentrated upon the large urban area. In fact, most of braille libraries are located in Seoul whereas a reading room for the visually handicapped in the public library system are exclusively placed in the large cities such as Inchon, Taejon, and Taegu. 5. All of the public library is neither equipped with necessary facilities to publish in braille nor secured supporting instruments which may facilitate library use for the visually handicapped. On the contrary, most of braille libraries are equipped with arrangements to publish in braille despite supporting devices are gererally lacking. 6. Consequently, provision of services In the public library is largely confined to reading and circulation of materials purchased from braille libraries while major task of braille libraries centers around publication and distributions of the reading materials in braille.

Three hundred and forty-five children(108 gifted children, 237 normal children), who were forth to sixth grade children, were taken the Children's NEO Personality Inventory(Big five traits and 17 facets). The results were as follos; 1. There are statistically significant differences in personality characteristics between the gifted and the normal children. The gifted children have higher tendency of openness, extraversion, conscientiousness, lower neuroticism than the normal children. There is no difference in agreeableness between the gifted and the normal children. In the subfactors(facets) of neuroticism, the gifted children have lower tendency of anxiety, hostility, depression, shyness, attention deficit than the normal children. In the subfactors of extraversion, the gifted children have higher tendency of assertiveness, gregariousness, cheerfulness than the normal children. In the subfactors of openness, the gifted children have higher tendency of fantasy, creativity, physical activity, high intellectual ability, flexibility, reactivity than the normal children. In the subfactors of agreeableness, the gifted were more warmth and altruism than the normal children. In the subfactors of conscientiousness, the gifted children have higher tendency of competence, achievement motivation, deliberation, dutifulness than the normal children. 2. There were no statistically significant differences in personality characteristics between the gifted girls and the gifted boys. In the subfactors of neuroticism the gifted boys have higher tendency of shyness than the gifted girls. In the of subfactors of extraversion, the gifted boys have lower tendency of sensation- seeking than the gifted girls. In the subfactors of openness, the gifted boys have higher tendency of intellectual ability than the gifted girls.

In order to obtain the basic information for the optimal settlement planning in the reclaimed area, various existing settlement conditions on reclaimed farming village were analysed through a case study of in-and-round farming villages in Deuk Ryang Reclaimed Area. By comparison study between in-and-around villages, the allocation policy of farming settlement in the samll and medium scale area was proposed. The results obtained in this study were as follows ; 1.The population structure of the inner village(Ansim village) had become worse than the around village during 1976~1981 period from the viewpoint of total and female emigration ratios. Especially, the originally unbalanced sex ratio of Ansim village had worsen to the unacceptable ratio of 1.5 : 1(male : female). Therefore, the structural stability of the population should be carefully improved in the newly reclaimed farming villages by the systematic long-term controlling machanism.2.The farming status of Ansim village was much lower than the around villages viewing of the cultivated acreage and agricultural machinery stock Therefore, the continuous and intensive governmental support different from the existing farming area should be required for the settling of reclaimed farming. 3. The regularity of the village site as a planned village, though pursed in the first phase of village construction, had been severely disturbed inflowing of squatters. Recently, there are increasing vaccant houses in the village, and the level of living amenities and personal mobility of Ansim village are much lower than the around village. So, now, the physical structure of the village should be improved to the level of village reconstruction or new village construction. 4. The cultivated area of Ansim village leans to the south side which would be unfavoured by the farmers of the around villages, while its distributing pattern should be concentric around the village site. This phenomenon disturbs the central fuction of the planned farming village. In this respect, role assignment, relationship and balance of competence in farming activities should be planned between in-and-around villages in the reclaimed area from the initial stage. 5. Putting together the above results in this study, the farming and living conditions of Ansim village threaten its existence as a planned new farming village in the reclaimed area. And, so, the full scale reconstruction of village structure, including moving to the new site, should be designed as soon as possible. Although further many studies should be carried out, it would be sure that the new village planning should be reconsidered in the small and-medium scale reclamation works.
