Objectives : The Levator Ani Muscles Training(LAMT) is one of the well known very effective prevention and treatment method of some specific diseases in the anal organs, digestion system, urinary organs and genital organs, which means LAMT could be considered as an independent exercise. Methods : Chinese databases were searched and found one good source named CNKI(China National Knowledge Infrastructure) where there were downloaded 154 articles, out of which were finally selected 82 used for the introduction of the historical background, health-effectiveness, working mechanism, training methods, etc. Results : LAMT as an independent exercise, is considered very effective for the prevention of diseases in the anal organs, e.g. hemorrhoids, anal fissure, rectal prolapse; urinary organs, e.g. urinary incontinence, frequent micturition; digestion system, e.g. visceroptosis, diarrhea, chronic enteritis; genital organs, e.g. prostatitis, impotence, premature ejaculation, feminine vaginal relaxation, sexual indifference, etc. It is also told LAMT is effective for coronary heart disease, hyperyension and varicose veins of lower extremity to a certain degree. LAMT is also very similar to the Kegel exercise in couple of aspects. They are equally effective for the urinary incontinence and impotence. Conclusions : LAMT as an independent exercise has developed and become more and more health-effective, especially through the combination with the Qigong exercise, and thus many training methods have been introduced. There are not many scientific research and development with very limited accomplishments even in China. It is strongly required to strengthen the research and development activities so that LAMT will become one of the very effective natural healing soonest possible.

Protein phosphatase 2A (PP2A), a family of serine/threonine protein phosphatases, plays an important role in balancing the phosphorylation status of cellular proteins for regulating diverse biological functions in eukaryotic organisms. Despite intensive studies in mammals, limited information on its role is available in filamentous fungi. Here, we investigated the functional roles of genes for a putative B' delta regulatory subunit (FgPP2AR) and a catalytic subunit (FgPP2AC) of PP2A in a filamentous ascomycete, Fusarium graminearum. Molecular characterization of an insertional mutant of this plant pathogenic fungus allowed us to identify the roles of FgPP2AR. Targeted gene replacement and complementation analyses demonstrated that the deletion of FgPP2AR, which was constitutively expressed in all growth stages, caused drastic changes in hyphal growth, conidia morphology/germination, gene expression for mycotoxin production, sexual development and pathogenicity. In particular, overproduction of aberrant cylindrical-shaped conidia is suggestive of arthroconidial induction in the ${\Delta}FgPP2AR$ strain, which has never been described in F. graminearum. In contrast, the ${\Delta}FgPP2AC$ strain was not significantly different from its wild-type progenitor in conidiation, trichothecene gene expression, and pathogenicity; however, it showed reduced hyphal growth and no perithecial formation. The double-deletion ${\Delta}FgPP2AR;{\Delta}FgPP2AC$ strain had more severe defects than single-deletion strains in all examined phenotypes. Taken together, our results indicate that both the putative regulatory and catalytic subunits of PP2A are involved in various cellular processes for fungal development in F. graminearum.

The androgenic gland secretes a hormone, androgenic gland hormone, which is believed to act on the differentiation of the primary, secondary, and behavioral sex characteristics in most malacostracan crustaceans. Based on the changes in gonado-somatic indexe and histological observation of testis and androgenic gland cell, testicular maturation and spermatogenesis of M. nipponense occurred early in summer (May to July), and generally spermatogenesis was absent in August. It could be, concluded that May to July is the period when adult males of this species are sexually active, and androgenic gland showed signs of increased secretory activity.

Gonad development in the sandfish Arctoscopus japonicus was investigated using a histological method. Specimens were collected monthly from April 2003 to March 2004, in the East Sea of Korea. The gonadosomatic index (GSI) of females began to increase in August, reached a maximum in November, and declined sharply in December. By contrast, in males, the GSI began to increase in June and reached a maximum in August. The annual reproductive cycle of A. japonicus can be divided into four successive stages in females: the early growing (January-March), late growing (April-August), ripe and spent (September-November), and recovery (December) stages. Males passed through early growing (January-April), late growing (May-July), ripe and spent (August-November), and recovery (November-December) stages. These results indicate that the spawning season was from October to December. The egg diameter of mature oocytes was 3.12$\pm$0.02 mm. The relationship between fecundity (F$_e$) and body length (BL) was F$_e$=0.4693BL$^{2.6825}$. Fecundity ranged from 483-2,254 eggs in a body length of 14.3-22.9 cm and increased with body length. The body length at 50% maturity was 14.80 cm, which corresponded to an age of 2.40 years.

This paper describes reproduction, population structure, growth and size at sexual maturity of a deep-water mud shrimp (Solenocera melantho) in the adjacent waters of Geomun Island, Korea. The shrimp was caught by a beam trawl from November 1998 to December 1999. Spawning period was estimated by gonadosomatic index to be from August to early November with a peak in October to early November. Female shrimps were $12\%$ matured at 16 mm in carapace length, $33\%$ matured at 18 mm and $75\%$ matured at 22 mm. The size at $50\%$ maturity for female was estimated to be 20.65 mm in carapace length. Breeding season was estimated to be from August to early November with a peak in October to early November. The size at $50\%$ inseminated was 19.81 mm CL. The fecundity was 87,500-405,200 and related exponentially to carapace length and total weight. This species survived between 25 and 26 months. The maximum carapace length of females and males were 48 mm and 34 mm respectively. Sex ratio was $51.3\%$, and the females were preponderant. Growth was estimated by modified von Bertalanffy growth function incorporating seasonal variation in growth in both years females (K=1.019/yr and $L_{\infty}$=51.731 mm CL) grew faster, reaching a larger size at a given age than males (K=1.848/yr, and $L_{\infty}$=27.499 mm CL). This is indicated by differences in growth performance indices $(\varphi')$ between females (3.291) and males (3.145).

Until now, we have a great progress in computer hardwares and computer softwares. Many people think these days as the information time or information society. Even though, we make a great progress in the computer science, we can not regard this society as the information society, if we do not accept the development of computer in our real life. In order to provide desirable residential environment for the information - society, it is necessary to review previous housing projects from the Industrial - Revolution to these days. Thus this study deals with limits of modern housings. This research also suggests a new housing concept for the information - society by reinterpretation of the Korean traditional houses. Use of space in the Korean traditional houses was mostly interpreted by the concept of sexual discrimination from Confucianism. However it is suggested in this study, that An-Chae is a home space for providing privacy of family and Sarang - Chae is a social space for providing social activity. Thus it is found that the Korean traditional house has been used as office as well as home. In this view, it is suggested that Korean traditional houses be the prototype of future house as a business space and also as a home space. In this study, 3 types of housing for the information - society are suggested; flat type, tower type and skip floor type. these houses have two entrances independently for the home space and the social space. Therefore each space has no interference with each other. Then one can do his own at home efficiently. He does not have to go to his office in downtown. One can relieve traffic congestions in the city and reduce air contamination.

Objectives: This study aims to examine the positive effects of developmental assets on the prevention of health risk behaviors among Korean adolescents. The framework of developmental assets was introduced as building blocks for healthy child and adolescent development by Benson and his colleagues. These assets represent positive external environmental factors and internal personal qualities which strongly influence the quality of life of adolescents. Methods: In 2001, we administered self-reported questionnaires to 3,739 girls and boys in grade 9 at eight schools in two cities, Chinju and Suwon in South Korea. The data was compiled into a 'Korean Youth Health Related Behaviors and Developmental Assets Survey' and then analyzed Youth health risk behaviors, which we measured in terms of their frequency, included tobacco, alcohol, and substance use, sexual intercourse, anti-social behaviors, violence, feelings of social isolation at school, depression or attempted suicide, absenteeism from school, gambling. Results: Overall, with respect to developmental assets, the Korean adolescents surveyed only 12.6 of the 40 assets, and 88 percent of adolescents had 20 or fewer of the assets. Based on their number of developmental assets(DA), adolescents were categorized into four groups: Group I(DA 0-10): Group II(DA 11-20): Group III(DA 21-30): Group IV(DA 31-40). We examined the differences in the frequency of each health risk behavior across the four groups, Group I-IV, and found that the frequency of most health risk behaviors decreased as the number of developmental assets increased. Conclusion: We therefore concluded that in order to make effective approaches for the prevention of health risk behaviors among adolescents, we should consider and develop more comprehensive and adolescents-based policy and programs to promote various aspects of adolescents' health and quality of life.

Manchurian trout (Brachymystax lenok) is an endangered fish species in East Asia including the Korean peninsula. To establish a method for artificial propagation and to improve our understanding of the reproduction in the species, we have produced recombinant gonadotropins, follicle-stimulating hormone (r-mtFSH) and luteinizing hormone (r-mtLH), which may play central roles in reproductive activities. In the present study, the biological activities of the recombinant hormones were analyzed by gonadosomatic index (GSI), ovarian follicle diameter, and sex steroid levels in mature rainbow trout (Oncorhynchus mykiss). In the 6th day post-injection, FSH-injected fish were slightly decreased in the GSI value, although there were no significant differences among those of control, r-mtFSH, and r-mtLH treatments. Injection of the r-mtFSH increased follicle diameters significantly as compared with those of control- and r-mtLH-injected fish. The plasma steroid levels showed wide differences in the groups at 1, 3, or 6th day post-injection. Despite the variable steroid levels, three individuals receiving either r-mtFSH or r-mtLH showed a great increase in a maturation-inducing steroid, $17{\alpha},20{beta}$-dihydroxy-4-pregnen-3-one, at 3 and 6 days. Taken together, these results suggest that biological efficacies of the recombinant FSH and LH should be further studied in the Manchurian trout.

The purpose of the study was to develop a Web site for the middle-aged women and test the usability of the site. Users' need for information were identified via online survey of 189 middle-aged women. It was found that they had various health problems but very few did any health prevention or health promotion activities. A web site for the middle-aged women was developed based on the result of needs assessment. The site includes content on exercise, diet including weight control, osteoporosis, climacteric, aging, breast and cervical cancer. Besides this health information, FAQ on women's health, my health knowledge test, statistics, link to related institutes and web sites, newspaper articles/mass media clips, journal articles, conferences, papers and other educational information were added. The site was developed as a subsystem of the Healthguide(http://healthguide.kihasa.re.kr). As a way of utilizing the homepage, twenty two women aged 40-50 were recruited at a community-based gathering and health promotion education program was conducted. To test the effectiveness of the education, knowledge, attitude and behavior changes of before and after education were compared. There were significant differences of knowledge and behavior in breast cancer, cervical cancer, osteoporosis, menopause and sexual life. It is expected that Web-based women's health information will contribute to women's health promotion and provide an effective learning media for health education.
