Research on fish biodiversit yof seagrass bed has been carried out in Indonesian waters, and the results vary between water locations.  This study aims to determine the biodiversity of fish based on seagrass density in the day and night period. This research was conducted in the waters of Tanjung Tiram, South Konawe from February to March 2018. Fish sampling based on seagrass density in the day and night period using gillnets with mesh size of 0.75, 1.25 and 1.50 inch.  Fish biodiversity found in this study consisted of 42 species from 24 families with an abundance of 1000 individuals. Fish biodiversity in densely seagrass beds was higher than low seagrass beds.Labridae family was the most doimnan fish during the daytime while at night is dominated by the family Plotosidae. The status of  fish biodiversity based on seagrass density was categorized as moderate to high and stable diversity while based on the day-night period was classified as moderate diversity with unstable to stable conditions, and the level of dominance of both was low.

<strong>The Carbon Stock and Potential Uptake of Seagrass Beds in the Northern and Eastern Part of Bintan Island.</strong> Seagrass is marine plant vegetation which have large potention on reducing carbondioxide emission effects in the environment. Nevertheless, the information about this potention is still limited, so the seagrass beds are still having less attention. Therefore, in April 2016 a research has done to estimate the potential of carbon stock and uptake at two location in Bintan Island, that were in the northern part (Pengudang Village) and in the eastern part (Teluk Bakau). Carbon stock estimation done by observing the seagrass density, meanwhile the carbon uptake by seagrasses was measured based on their growth/production rate. Its was known from the observation that the carbon stock potention of seagrass beds in both locations were almost at the same value, which were 133.24 gC/m<sup>2</sup> (in the northern side) and 133.71 gC/m<sup>2</sup> (in the eastern side). Nevertheless, the uptake of carbon (carbondioxide) which is used by segrass to produce leaves was higher in the eastern side at 0.50 gC/d/m<sup>2</sup> than in the northern side at 0.10 gC/d/m<sup>2</sup>. From that productivity, the carbon storage rate by seagrass beds are 0.0630 gC/d/m<sup>2</sup> in the north and 0.3375 gC/d/m<sup>2 </sup>in the east. Thus, seagrass bed area in the eastern side of Bintan Island (Teluk Bakau) was having higher carbon stock and uptake potential than in the northern side (Pengudang).

The article presents two letters from V.A. Musin-Pushkin which he wrote to his bride shortly before the wedding in 1828 (the letters are kept in the Russian State Archive of Ancient Acts). The text of the letters reflects the context of the time and everyday life, the system of views and the peculiarities of the worldview of a young aristocrat, the specific features of intra-family interaction in the field of feelings, marriage, human relations which inevitably turn out to be associated with the concepts of the family honor, family duty, the need to preserve the status of a noble family. The author traces how the power hierarchy is manifested at the level of relations within a close circle of relatives, as well as how traditional patterns are combined with new elements. Vladimir Alekseevich Musin-Pushkin, the youngest son of the archaeographer Count A.I. Musin-Pushkin, was arrested in connection with the case of the Decembrists, transferred from the Guards to the army and exiled to serve in Finland, where he met his future wife, Emilia Karlovna Shernval von Wallen. The article provides details of the family life of this married couple, as well as private facts from the biography of some other members of the Musin-Pushkin family.

Bryophytes are the second largest group of land plants and are also known as the amphibians of the plant kingdom. 67 species of bryophytes have been reported from select locations across the state of Gujrat. The status of family fissidentaceae which is a large moss family is being presented in this paper. Globally the family consists of 10 genera but only one genus, Fissidens Hedw. has been collected from Gujarat. Fissidens is characterized by a unique leaf structure and shows the presence of three distinct lamina, the dorsal, the ventral and the vaginant lamina. A total of 8 species of Fissidens have been reported from the state based on vegetative characters as no sporophyte stages were collected earlier. Species reported from the neighboring states also showed the absence of sporophytes. The identification of different species was difficult due to substantial overlap in vegetative characters. Hence a detailed study on the diversity of members of Fissidentaceae in Gujarat was carried out between November 2013 and February 2015. In present study 8 distinct species of Fissidens have been collected from different parts of the state. Three species Fissidens splachnobryoides Broth., Fissidens zollingerii Mont. and Fissidens curvato-involutus Dixon. have been identified while the other five are still to be identified. Fissidens zollingerii Mont. and Fissidens xiphoides M. Fleisch., which have been reported as distinct species are actually synonyms according to TROPICOS database. The presence of sexual reproductive structures and sporophytes for several Fissidens species are also being reported for the first time from the state.

The family Myriangiaceae is relatively poorly known amongst the Dothideomycetes and includes genera which are saprobic, epiphytic and parasitic on the bark, leaves and branches of various plants. The family has not undergone any recent revision, however, molecular data has shown it to be a well-resolved family closely linked to Elsinoaceae in Myriangiales. Both morphological and molecular characters indicate that Elsinoaceae differs from Myriangiaceae. In Elsinoaceae, small numbers of asci form in locules in light coloured pseudostromata, which form typical scab-like blemishes on leaf or fruit surfaces. The coelomycetous, “Sphaceloma”-like asexual state of Elsinoaceae, form more frequently than the sexual state; conidiogenesis is phialidic and conidia are 1-celled and hyaline. In Myriangiaceae, locules with single asci are scattered in a superficial, coriaceous to sub-carbonaceous, black ascostromata and do not form scab-like blemishes. No asexual state is known. In this study, we revisit the family Myriangiaceae, and accept ten genera, providing descriptions and discussion on the generic types of Anhellia, Ascostratum, Butleria, Dictyocyclus, Diplotheca, Eurytheca, Hemimyriangium, Micularia, Myriangium and Zukaliopsis. The genera of Myriangiaceae are compared and contrasted. Myriangium duriaei is the type species of the family, while Diplotheca is similar and may possibly be congeneric. The placement of Anhellia in Myriangiaceae is supported by morphological and molecular data. Because of similarities with Myriangium, Ascostratum (A. insigne), Butleria (B. inaghatahani), Dictyocyclus (D. hydrangea), Eurytheca (E. trinitensis), Hemimyriangium (H. betulae), Micularia (M. merremiae) and Zukaliopsis (Z. amazonica) are placed in Myriangiaceae. Molecular sequence data from fresh collections is required to confirm the relationships and placement of the genera in this family.

Despite the positive developments in the sphere of ensuring the special needs of disabled children, a comprehensive socio-hygienic assessment of the conditions and lifestyles, as well as of their families, has not been carried out in the recent years. The purpose of the study is to identify, through a sociological survey, the problems that a disabled child encounters in his life, in order to further improve the provision of medical and social assistance to him. Materials and methods of research: 506 legal representatives of minors (aged 0–17 years) with the status of a disabled child were interviewed. Study design: single-center, non-randomized, uncontrolled. Results: the study of the living conditions of a disabled child in the family, the assessment by the parents of the state of his health, the problems arising during the registration of disability, in the provision of medical and rehabilitation assistance, and issues of medical and social support, made it possible to determine the position of this part of the child population in modern legal and medical and social conditions. The main problems were the large number of documents required for the registration of a disability, the long wait for the day of the examination, the remoteness of the location of the medical and social examination bureau, the shortage of specialist doctors, the problem with subsidized drugs, the lack of taking into account the individual needs of the child when carrying out rehabilitation programs, the need to contact different organizations and departments, lack of medical and social assistance, violation of rights in the provision of medical services to a disabled child. Conclusion: The acquired information is important for the further improvement of the provision of medical and social assistance to handicapped children and children with disabilities. The main task today is to develop mechanisms for fulfilling the declared rights and freedoms of persons with disabilities and the obligations undertaken by the state in relation to them. The principle of individualization of the provision of various benefits, depending on the condition of a disabled child, his needs, material security, remains relevant.

In the world of day-care research, the status of our knowledge is sufficiently shaky that we must continue to keep an open mind about the service. The knowledge base is growing rapidly, but the conceptual structure that supports it is flimsy and insubstantial. Fortunately, current research efforts are improving this situation. Regardless of whether we like or dislike day care, it is, like the family, here to stay. That realization alone should strengthen our resolve not to compromise on the type of service we create. We have to continue to identify parameters of quality and become good matchmakers in terms of child care, family, and child characteristics. Through such efforts, a network of educare programs that will foster favorable development in children can become a national and global reality.

Abstract This paper examines what set of familial circumstances allow for the justifiable interference with the right to respect for family life under Article 8, echr. We analyse all the Courts’ judgments on adoptions from care to find out what the Court means by a “family unit” and the “child´s best interest”. Our analysis show that the status and respect of the child’s de facto family life is changing. This resonates with a view that children do not only have formal rights, but that they are recognised as individuals within the family unit that states and courts must address directly. Family is both biological parents and child relationships, as well between children and foster parents, and to a more limited extent between siblings themselves. The Court’s understanding of family is in line with the theoretical literature, wherein the concept of family reflects the bonds created by personal, caring relationships and activities.
