Abstract
The Hishikari high-grade low-sulfidation epithermal gold deposit is located in the Hokusatsu district, about 30 km north of the Kagoshima International Airport, Kagoshima Prefecture (Fig. 1). In early 1981, a narrow (15 cm) but high-grade (290 g/t Au) vein was discovered 200 m below the surface by the Metal Mining Agency of Japan (MITI, 1982), and subsequent development has proved Hishikari to have substantial reserves of high-grade ore. Production from July 1985 to March 2000 totaled 105 tonnes (t) of gold and 58 t of silver from 1.87 Mt of ore. The production plus total reserves are estimated to be 5.5 Mt, including 3.5 Mt at an average grade of 60 to 70 g/t Au in the Honko-Sanjin ore zone and 2 Mt at 20 to 25 g/t Au in the Yamada ore zone, for a total of approximately 260 t of contained gold.
The Hishikari deposit, especially the Honko-Sanjin zone, is characterized by high gold contents in almost all veins and by a very high aluminum content in the veins due to abundant adularia and common smectite. This article presents a summary of the gold deposit at Hishikari and the detailed mineralogical description of a high-grade vein, the Hosen no. 1 vein, hosted by basement sedimentary rocks.
Geology and Geophysical Expression of the Yamagano Low-Sulfidation Epithermal Au-Ag Deposit, Southwest Kyushu, Japan
Authors: Murakami Hiroyasu , Feebrey Craig A. 
Published: August 2024

Abstract
The Yamagano deposit represents the third-largest known gold deposit in the Hokusatsu region of southern Kyushu. Its total historical gold production is 28.4 tonne (t) (Society of Resources and Material, 1989), which places it sixth in terms of gold-producing mines in Japan. Gold mineralization in Japan is dominated by low-sulfidation epithermal deposits of which the Yamagano deposit is typical, and like all other deposits of this style (with the exception of Hishikari) it has ceased production.
Kushikino Gold Mineralization in a Pliocene Volcanic Region, Kyushu, Japan
Authors: Izawa Eiji , Zeng Nanshi 
Published: August 2024

Abstract
The Kushikino gold mine (Gold Park) is located 30 km northwest of Kagoshima city (Fig. 1) and historically has been the fourth largest gold mine in Japan. The mine was opened in 1660 by a lord of the Satsuma Province (a province in southern Kyushu during the Edo era) and development took place mainly on the Serigano vein group (Fig. 2) in the south central part of the area (Miyahisa and Wakabayashi, 1972). In the late Meiji era, 1905, Mitsui Mining and Smelting Co., Ltd. acquired the central part of the Kushikino area including the Kushikino no. 1 vein. In 1913, an all-slime cyanidation plant, the first of its kind in Japan at that time, began treating ore at a rate of 150 (t) per day. Since 1660 the mine has produced 55 t of gold and 497 t of silver, of which more than 80 percent was produced from the Kushikino no. 1 vein. Approximate average Au and Ag grades have been reported as 6.7 g/t and 61 g/t, respectively (MITI, 1979).
In 1988, the Kushikino Gold Park was opened adjacent to the operating gold mine. In the park, the western part of the champion vein (Kushikino no. 1 vein) around the “New” inclined shaft (Shin-shako) can be seen in the adit (mine level 2L, 60 m above sea level), though the mining operation is no longer active. This article compiles previous studies and revises our understanding of the epithermal gold mineralization at the Kushikino deposit.

Abstract
Onta pottery and the Onta-Yamakuni gold areas are located in the northwestern part of the Neogene Hohi volcanic zone, northern Kyushu. Hydrothermally altered volcanic rocks in the area host gold-bearing quartz veins and clay deposits. The Asahi mine had produced at least 0.3 tonnes (t) of gold during a 12-year production period between 1935 and 1953.
Kiruna-Type Low Ti, Fe Oxide Ores and Related Rocks, Adirondack Mountains, New York
Authors: McLelland James , Foose Michael P. , Morrison Jean 
Published: August 2024

Abstract
Adirondack iron ores consist primarily of massive magnetite that generally occurs in layers or in elongated shoots parallel to fold axes. The magnetite is commonly accompanied by REE-enriched apatite and aegerine-augite. Hand lens inspection of ore reveals numerous octahedra indicating that the ore is either undeformed or recrystallized. The ore is invariably associated with various subunits of Lyon Mt. Granitic Gneiss (LMG), which are either in close proximity or serve as the host rock. A strong correlation exists between occurrences of ore and the presence of albitic subunits of LMG. Detailed investigations of these subunits demonstrate that they result from replacement of LMG microperthite by almost pure albite (˜Ab98). The replacement process can be followed through initial stages of checkerboard albite and finally to quartz-albite rocks. Magnetite concentrations commonly occur in proximity to these rocks and almost every magnetite deposit hosted by granitoids shows evidence of checkerboard albite in the wall rocks.
Thin section examination of several layered magnetite deposits demonstrate that they are intimately interleaved with highly deformed feldspathic wall rock that is grain size reduced and contains rolled feldspars reflecting shear strain. Present in the magnetite are crystals of bright green aegerine-augite interpreted to be coeval with the ore and undeformed even at their edges. This observation indicates that the magnetite is also postdeformational, an interpretation supported by narrow veinlets of magnetite that cut deformed feldspar tails at high angles but remain undeformed. It is proposed that ore constituents were transported through, and deposited within, fracture systems that localized iron-bearing fluids. An origin of this sort is consistent with either hydrothermal or immiscible magmatic processes. The latter possibility is considered to be unlikely, since the magnetite appears to be in equilibrium with the several silicate phases that it is in contact with. Moreover a hydrothermal origin is supported by the ubiquitous presence of checkerboard albite.
Oxygen isotope studies indicate that the sodic, ore-bearing hydrothermal fluids equilibrated with wall rocks and ore at temperatures of 600°–700°C. The large scale of sodic alteration and magnetite deposition are best explained by a regional fluid of surface origin that evolved into saline brines either by evaporation or by interaction with evaporitic deposits. Such fluids are commonly associated with rare-earth-enriched, Kiruna-type, low Ti, Fe oxide deposits similar to those present in the Adirondacks.
The Other Side of Mining

Abstract
The Elizabeth mine was listed as a Superfund site in June, 2001, mainly because of the impacts of mine drainage from the site on the Ompompanoosuc River. The site is unusual because the community values some of historic aspects of the site that are causing the environmental problem. The site is also eligible for the National Register of Historic Places; therefore, the National Historic Preservation Act is an additional regulation applicable to the cleanup.
The Superfund law authorizes two kinds of response actions: (1) Short-term removals, where actions may be taken to address releases or threatened releases requiring prompt response, and (2) Long-term remedial response actions designed to permanently and significantly reduce the dangers associated with a release or threat of a release of hazardous substances, where the release is serious, but not immediately life threatening. Both types of actions are under consideration at the Elizabeth mine.
The U.S. Environmental Agency (EPA) has collected surface-water and sediment-chemistry data, performed surface-water and sediment toxicity tests, surveyed benthic community density and diversity (infauna and epifauna), and performed periphyton assessments, and other studies to evaluate fish abundance and assess potential human health impacts. Surface-water quality within Copperas Brook, the stream that drains the mine site, and within the mixing zone of the Copperas Brook confluence with the West Branch of the Ompompanoosuc River is clearly impacted by acid mine drainage from the site. The levels of contaminants detected in Copperas Brook and the mixing zone are many times higher than the Vermont Water Quality Standards and EPA accepted criteria.
Because of the applicable regulations, EPA has two major goals for the Elizabeth mine cleanup: (1) protect human health and the environment by preventing acid mine drainage formation; and (2) minimize impacts on the historic resources. Five cleanup options are proposed to meet these goals. All options include plans to preserve historic resources, divert surface water, stabilize slopes and cap or cover flotation tailings piles, and collect and passively treat remaining drainage. The options vary in the amount of rain and/or snowmelt water allowed to infiltrate through the cover/cap. The balance between historic preservation and cleanup costs will culminate in a decision regarding the amount of additional long term operation and maintenance costs that are acceptable to preserve this resource. EPA, in concert with the State of Vermont, will officially propose one of the approaches and allow time for public feedback. After consideration of public comments, EPA will implement a cleanup plan. It is expected that the cost of an early removal cleanup will be in excess of $10 million.

O objetivo desse artigo consistiu em identificar as dificuldades que as pessoas com deficiência encontram no mercado de trabalho, tendo como referência os artigos científicos disponibilizados na base de dados Google Acadêmico, redigidos em língua portuguesa, e publicados no Brasil, no período de 2011 a 2021. Nesse sentido, foi utilizada uma amostra integrada por 15 artigos, nos quais foram observados elementos, como: as características gerais dos trabalhos e dos seus autores; a quantidade de publicações; as metodologias utilizadas nas pesquisas, os objetivos comuns e resultados alcançados; a frequência das dificuldades enfrentadas pelas pessoas com deficiência nas organizações. Constatou-se que a maioria dos trabalhos evidencia a carência de acessibilidade, a falta de qualificação profissional e o preconceito, como dificuldades predominantes enfrentadas pelas pessoas com deficiência após ingressarem no mercado de trabalho. Além disso, o número reduzido de artigos publicados no período selecionado aponta para a pouca visibilidade do assunto na área de Administração.

Artinya ada hubungan bermakna antara pengetahuan keluarga dengan kekambuhan pasien skizofrenia, ada hubungan bermakna antara sikap keluarga dengan kekambuhan pasien skizofrenia, dan juga ada hubungan bermakna antara pendapatan keluarga dengan kekambuhan pasien skizofrenia. Diharapkan bagi tenaga kesehatan untuk memberikan promosi kesehatan terkait kekambuhan pasien skizofrenia kepada keluarga, sehingga keluarga pasien mendapatkan infomasi yang cukup terkait kekambuhan dan dapat meringankan beban ekonomi dari keluarga pasien skizofrenia dengan mencegah terjadinya kekambuhan dan menurunnya stigma dimasyarakat tentang penderita skizofrenia supaya keluarga merasakan kenyamanan dan berkurangnya perasaan terganggu yang berasal dari penghakiman masyarakat serta dapat meringankan beban yang dialami oleh keluarga dan mencapai kepada tingkat penerimaan keluarga yang baik.
Assessing L1 Competence Decline among Yoruba-English Bilingual Undergraduates at Usmanu Danfodiyo University, Sokoto
Authors: Aremu Abdulahi Olarewaju 
Published: August 2024

This study sets out to investigate the extent of lack of competence in Yoruba among Yoruba-English bilingual undergraduates at Usmanu Danfodiyo University, Sokoto. A mixed-methods approach was adopted for interpretations to be drawn based on the combined strengths of both datasets (i.e., quantitative and qualitative data). 123 participants, 76 males, and 47 females, completed the questionnaires, while interviews were conducted with 11 participants, 8 males and 3 females, to validate their self-assessment and gain a deeper understanding of their language abilities through open-ended questions and direct observations. Quantitative data analysis involved frequency and percentage calculations, with subsequent interpretation and discussion. Qualitative analysis entailed transcribing the interviews, interpreting the responses, and discussing the findings. Both quantitative and qualitative results were compared, and the extent to which they confirmed each other was established. Findings show that a substantial number of participants exhibited a moderate ability in their L1. Although both the current and the earlier studies point towards the decline in Yoruba competence among the young generation, particularly compared to the older generation, the current study delves deeper into participants’ competence levels through various tasks like speaking, translating, and interpreting idioms. The coverage of areas such as numeracy, days of the week, and months of the year is unique to this study as they have not been previously explored.
Лізинг як форма оновлення технічної бази підприємств
Authors: Шапошников К. С. , Мусійчук Д. В. , Пастух В. Л. 
Published: August 2024

Інвестиції в оновлення технічної бази є життєво важливими для успіху будь-якого суб’єкта господарювання, тому лізинг обладнання стає популярнішим серед компаній, ніж пряма купівля. Лізинг надає широкий вибір об’єктів, а також дає фінансову можливість отримати обладнання, придбання якого іншим способом було б надто дорогим. У статті досліджено основні складові процесу лізингу, які необхідно враховувати при прийнятті управлінцями відповідного рішення: термін лізингу обладнання, його залишкову вартість, справедливу ринкову вартість, умови платежу, варіанти завершення лізингової послуги. Визначено, що процес надання лізингової послуги включає ряд взаємопов’язаних етапів: дослідження та підготовка лізингової угоди; ведення переговорів, досягнення згоди та підписання договору лізингу; доставка та приймання обладнання лізингоодержувачем; здійснення щомісячних/квартальних платежів; повернення або оновлення обладнання. У статті доведено, що лізинг може не тільки допомогти підприємству керувати грошовими потоками, він також може покращити фінансову звітність: баланс та звіт про фінансові результати. Доказано, що лізинг також можна використовувати як захист від прогресу технологій, так як підприємство може використовувати лізинг для своєчасного придбання новітніх технологій. Доведено, що ще однією перевагою лізингу є швидкість оформлення договору лізингу та гнучкість умов договору. Крім того, якщо порівнювати фінансові аспекти лізингу з купівлею обладнання, то лізинг коштує в рази дешевше. Таким чином, дослідження показало, що механізм впливу лізингового фінансування діяльності підприємства є незаперечним і вимагає постійного розвитку, оскільки лізинг є альтернативним джерелом фінансування придбання обладнання. Завдяки перевагам лізингу підприємства отримали додаткове джерело фінансових ресурсів для створення чи розвитку підприємницької діяльності.
