Perkawinan merupakan peristiwa yang unik sebab perkawian merupakan cara memperekat simpul kekelurgaan Secara sosiologis bahwa masyarakat bugis pinrang telah taat dan patu terhadap hukum. Akan tetapi penerapan pencatatan perkawinan belum dilaksanakan secara maksimal. Karena masih terdapat beberapa pasangan yang belum tercatatkan perkawinannya.Kebiasaan tersebut merupakan bukti bahwa budaya hukum belum terbangun secara maksimal. Perkawinan yang tidak tercatat akan memilik dampak hukum kepada anak dan istri. Perkawinan yang tidak tercatat semestinya perlu mendapatkan perlindungan hukum, bukan untuk dibiarkan tanpa memberikan solusi. Bentuk perlindungan itu dituangkan dalam bentuk tekhnis dengan memberikan peluang untuk melakukan itsbat nikah atas perkawinan yang telah dilangsungkan menurut syariat agama Islam, tetapi tidak dicatat oleh pegawai yang berwenang. Isbat nikah diperuntukkan pada hal tertentu saja sebagaimana yang terdapat dalam pasal 7 ayat (3) KHI. Keberadaan Pasal ini memberikan perlindungan hukum dengan memberikaan peluang mengajukan permohonan isbat nikah. Sehingga pernikahan yang belum tercatat, dapat dicatatkan dan diakui secara administratif, sehingga menjadi pernikahan yang diakaui secara yuridis formal atau legal.

Published: July 2019

Increased fragmentation and considerable environmental changes in native forests caused by the timber-oriented forest managements are threatening the biodiversity of forests. As a remediation, uneven-aged approach is recommended during forest management, because this is less intensive and could be less harmful than even-aged practices. We tested the effects of clear-cutting (as even-aged method) and group selection harvesting (as uneven-aged method) on carabids in lowland oak forests. Pitfall traps and litter sifting were used during the study.
We found that the total number of species was significantly higher in the gaps harvested by group selection and in the clear-cut than in the mature forests (control area). The species richness of forest specialist species was significantly lower in the clear-cuts than in the other area. Our findings demonstrated that the conventional clear-cutting caused a decrease in the number of forest specialist species. Therefore, group selection method should be favoured during forest management to maintain diversity.

Fire supports landscape openness; thus, prescribed burning could be an effective management in open landscapes. In this study we tested the response of arthropods (spider, ground beetle, rove beetle and woodlouse) to dormant-season prescribed burning in dry grassland patches. We hypothesized that the unburned patches support the arthropods recolonizing the burned patches; thus, fire causes no serious damage to the arthropod assemblages.
Epigeic arthropods (spider, ground beetle, rove beetle and woodlouse) were collected by unbaited pitfall traps containing ethylene glycol as a killing-preserving solution. Altogether 60 traps worked in 3 burnt and 3 control plots (10 traps/plot). Traps were emptied monthly from May to October in the year after burning. Collected arthropods were identified at species level using standard keys.
We found no significant difference between the burned and control plots for the abundance, species richness, and Shannon diversity of spiders, ground beetles, rove beetles and woodlice. Differences in total abundance, species richness and diversity of arthropods were also not significant between the burned and control plots. Among from 12 most abundant species, ten species was not affected by burning, while the abundance of Titanoteca veteranica spider species increased and the abundance of Trochosa robusta spider species decreased in the burnt plots.
Microcaves and other unburned microhabitats in and around the burned patches serve as refuge for epigeic arthropods supporting the fast recolonization after prescribed burning, although the abundance of some epigeic spider species (Titanoteca veteranica, Trochosa robusta) was affected by burning. Our findigs revealed that prescribed burning is a potentially promising conservation method. We also highlighted that preservation of unburned microhabitats and surroundings of the managed patches is essential during the prescribed burning.
Unattached Fraction of Radon Decay Products as a Crucial Parameter for Radon Dosimetry in Postojna Cave

V letih od 1998 do 2001 smo v zraku Postojnske jame na najnižji točki merili koncentracijo radona (CRn) in radonovih kratkoživih razpadnih produktov (CRnDP), ravnotežni faktor (F), delež nevezanih radonovih razpadnih produktov (fun), zračni tlak (P), relativno vlažnost zraka v jami (RH) in temperaturo zraka v jami (Tin) ter zunaj (Tout). Poseben poudarek je bil na fun in na njegovi odvisnosti od vremenskih razmer. Vrednosti fun so bile v širokem razponu, od 0,10 do 0,68. Z uporabo novega dozimetrijskega modela smo na osnovi izmerjenih vrednosti fun izračunali dozne pretvorbene faktorje in ugotovili, da so bili znatno višji od 5 mSv/WLM, to je vrednosti, ki jo priporoča metodologija ICRP-65. Tako so dejanske doze, ki jih prejmejo jamski vodiči, v povprečju za faktor 8 poleti in za faktor 2,7 pozimi višje od vrednosti, ki jih dobimo po dosedanji metodologiji ICRP-65.Short-term summer and winter monitoring was carried out at the lowest point in Postojna cave, on air concentrations on radon (CRn) and radon decay products (CRnDP), the equilibrium factor (F) and unattached fraction of radon decay products (f un ), barometric pressure (P), relative air humidity in the cave (RH) and air temperature outside (T out ) and in the cave (T in ), with the emphasis on f un . Dose conversion factors (DCF) for mouth and nasal breathing were calculated from the f un values (ranging from 0.10 to 0.68) and effective doses for the employees in the cave were obtained. These signifi cantly exceed the doses based on the ICRP-65 methodology now in use.
Common Cutaneous Neoplasms in Patients with Immunodeficiency: A Case Series

Published: July 2019

Abstract
Through humoral and cell-mediated mechanisms, the immune system plays a vital role in protecting every organ system. Disorders of the immune system may result in various cutaneous manifestations, including cutaneous malignancies. In patients with immunodeficiency, the risk of development of malignant cutaneous neoplasms is substantially increased. This increased risk may be due to oncogenic viruses that find a suitable microenvironment for tumorigenesis and cancer development. A subset of cutaneous malignancies that develop in patients with immunodeficiency may show aggressive clinical and biological behavior. Here, we report six cases of highly aggressive and deadly cutaneous neoplasms that arose in patients with a known history of immunodeficiency: two cases of Kaposi sarcoma in patients with immunosuppression due to human immunodeficiency virus infection; a case of Merkel cell carcinoma and a case of squamous cell carcinoma (SCC) in patients receiving immunosuppressive drugs after organ transplant; a case of multiple cutaneous tumors, including invasive melanoma, SCC, and sebaceous carcinoma, in a patient with hypogammaglobulinemia and a history of organ transplant; and a case of basal cell carcinoma and melanoma in situ in a patient with primary immunodeficiency.

Published: July 2019

Abstract. The 2-D distinct element method (DEM) code (PFC2D_V5) is
used here to simulate the evolution of subsidence-related karst landforms, such
as single and clustered sinkholes, and associated larger-scale depressions.
Subsurface material in the DEM model is removed progressively to produce an
array of cavities; this simulates a network of subsurface groundwater
conduits growing by chemical/mechanical erosion. The growth of the cavity
array is coupled mechanically to the gravitationally loaded surroundings,
such that cavities can grow also in part by material failure at their
margins, which in the limit can produce individual collapse sinkholes. Two
end-member growth scenarios of the cavity array and their impact on surface
subsidence were examined in the models: (1) cavity growth at the same depth
level and growth rate; (2) cavity growth at progressively deepening levels
with varying growth rates. These growth scenarios are characterised by
differing stress patterns across the cavity array and its overburden, which
are in turn an important factor for the formation of sinkholes and
uvala-like depressions. For growth scenario (1), a stable compression arch
is established around the entire cavity array, hindering sinkhole collapse
into individual cavities and favouring block-wise, relatively even
subsidence across the whole cavity array. In contrast, for growth scenario (2), the stress system is more heterogeneous, such that local stress
concentrations exist around individual cavities, leading to stress
interactions and local wall/overburden fractures. Consequently, sinkhole
collapses occur in individual cavities, which results in uneven,
differential subsidence within a larger-scale depression. Depending on
material properties of the cavity-hosting material and the overburden, the
larger-scale depression forms either by sinkhole coalescence or by
widespread subsidence linked geometrically to the entire cavity array. The
results from models with growth scenario (2) are in close agreement with
surface morphological and subsurface geophysical observations from an
evaporite karst area on the eastern shore of the Dead Sea.
