Air lindi merupakan jenis air limbah khusus yang mengandung berbagai macam polutan yang bersifat toksik terhadap lingkungan. Studi terkait karakteristik air lindi dilakukan dengan tujuan untuk mengetahui karakteristik air lindi sebelum diolah di IPAS 3 TPST Bantargebang agar dapat dijadikan dasar manajemen pengolahan air lindi di TPST Bantargebang. Sampel air lindi diambil pada inlet dan outlet IPAS 3 pada tanggal 31 Maret 2023. Sampel air lindi diambil menggunakan teknik grab sampling sebanyak 2 buah dengan volume tiap sampel sebanyak 2 liter. Pengujian air lindi dilakukan untuk parameter pH, BOD5, COD, dan Hg. Berdasarkan pengujian dan analisis didapatkan nilai tiap parameter pada inlet dan outlet berturut-turut sebesar 8,6; 933 mg/L; 3110 mg/L, dan 0,1896 mg/L sedangkan 6,75; 44 mg/L; 146 mg/L; dan <0,0005 mg/L. Nilai rasio antara BOD5 dan COD sebelum pengolahan sebesar 0,3 sehingga tergolong ke dalam air lindi usia sedang, meskipun TPST Bantargebang tergolong ke dalam usia tua. Berdasarkan nilai tersebut, maka jenis pengolahan saat ini, yaitu aerasi, koagulasi-flokulasi, dan sandfilter sudah cukup baik dalam mengolah tipe air lindi ini yang ditandai dengan pemenuhan baku mutu untuk seluruh parameter. Namun, parameter Hg perlu monitoring khusus dikarenakan toksisitas dan konsentrasinya yang tergolong tinggi.

Pembangkit Listrik Tenaga Sampah (PLTSa) merupakan salah satu pengelolaan sampah yang terdapat di TPST Bantargebang. PLTSa merupakan pembangkit listrik yang memanfaatkan sampah rumah tangga atau sampah sejenis rumah tangga sebagai bahan bakar untuk menghasilkan listrik Akan tetapi, eksistensi PLTSa memberikan dampak negatif, yaitu penurunan kualitas udara. Tujuan penelitian ini adalah mengetahui dispersi gas SO2 dan NO2 menggunakan model dispersi Gaussian. Terdapat dua sampel yang diukur, yaitu sampel gas emisi dan parameter meteorologi. Metode pengumpulan data menggunakan metode purposive sampling. Pengukuran gas emisi dilakukan di cerobong PLTSa. Pengelolaan hasil data pengukuran menggunakan AERMOD View untuk dispersi gas emisi. Pemodelan dispersi setiap gas emisi dilakukan dengan dispersi selama 1 jam, 24 jam, dan 1 tahun. Konsentrasi gas SO2 2,61 mg/Nm3 dan konsentrasi gas NO2 149 mg/Nm3 masih berada di bawah baku mutu yang ditetapkan dalam PERMENLHK Nomor 15 Tahun 2019, dengan baku mutu gas SO2 adalah 210 mg/Nm3 dan gas NO2 adalah 470 mg/Nm3. Hasil dari pemodelan dispersi menggunakan AERMOD View menunjukan bahwa dispersi gas emisi cenderung menetap pada sumber pencemar atau PLTSa dan konsentrasi gas menurun seiring bertambahnya jarak dari PLTSa.

Pengolahan air asam tambang dengan kandungan logam terlarut berupa besi (Fe) dan mangan (Mn) saat ini cenderung hanya dengan menambahkan bahan kimia. Namun, hal tersebut membutuhkan biaya yang besar dan harus dilakukan secara terus-menerus. Oleh sebab itu penerapan sistem lahan basah buatan (constructed wetland) menggunakan tanaman dan penambahan bahan organik dapat menjadi pilihan alternatif, karena tidak memerlukan biaya yang terlalu tinggi dan mekanismenya lebih sederhana. Tujuan dari penelitian ini adalah mengetahui pengaruh constructed wetland dengan penambahan bahan organik terhadap pH dan konsentrasi logam Fe dan Mn. Penelitian ini menggunakan 12 reaktor yang terbagi atas empat perlakuan, dengan perbedaan komposisi bahan organik. Pada setiap reaktor diisi dengan air asam tambang, tanah, bahan organik dan tanaman ekor kucing (Typha latifolia). Bahan organik yang digunakan berupa kompos dan tandan kosong (tankos) kelapa sawit. Masing-masing parameter (pH, Fe, dan Mn) diukur setiap lima hari selama 15 hari. Data yang dihasilkan selanjutnya dihitung menggunakan rumus efektivitas dan dianalisis menggunakan uji two way. Hasil penelitian menunjukkan bahwa constructed wetland dengan penambahan bahan organik mampu meningkatkan pH dari 3,8 menjadi 7,39 serta menurunkan konsentrasi Fe dari 3,2 mg/l menjadi 0,11 mg/l dengan efektivitas 96,46% dan Mn dari 6,5 mg/l menjadi 0,03 mg/l dengan efektivitas 99,49%.

Transformation of the state planning system — from state programs to national projects: the experience of Russia
Authors: Roslyakova N. , Vechkinzova E.
Published: January 2024

Object: Today, almost all countries of the world use a program-target approach to the development of the country's economy. Regional, industrial and government programs, national projects have become an integral part of the country's socio-economic activity, a tool for solving topical problems and achieving specific goals in various sectors of the economy. The transition from the format of state programs to national projects means changing the approach to solving topical issues. National projects are a direct state response to current system requests from society. The new state management format also requires the revision of the mechanism of selecting monitoring and updating of development projects. The purpose of this article is to study the practice of managing current national projects in Russia as a development tool.Methods: During the research, the methods of comparative analysis of the practice of selection and evaluation of the effectiveness of national projects in the regions of Russia; analysis of the expert opinions on the experience of monitoring and implementing existing national projects of Russia have been applied.Results: In the result of research the mechanisms of selection, monitoring and re-enabling projects into the system of national projects of Russia; the problems of coordination and linking the mutual interests of the beneficiarys and administrators of projects and ways to develop the mechanisms of coordination of interest have been identified.Conclusions: Summarizing the studied experience of Russia in the transition from state programs to national projects, a new approach to the mechanism of dynamic monitoring and update of projects can be highlighted, when projects with low implementation efficiency are excluded from the composition of national projects. In their place, from the projects that have passed the examination and have a high assessment of the quality of their development come from “basement of projects”. Despite this positive practice in the management of national projects, the following problem areas can be identified: systemic management problems, poor planning quality in the formation of a system of project indicators, motivational problems.

The study of the object is based on the model of text-derivatological and linguoaxiological analyses of derived texts, which are considered in formal, content and functional terms. The results of the study showed that the texts of Kazakhstani Internet comments prevail with value potential. The level of the value potential of everyday political discourse was revealed by the number of used keywords of the original text in the production of secondary texts. The scientific novelty of the research lies in the linguo-personalogical and linguoaxiological comprehension of the dominant textual activity when generating Internet comments in the Kazakh virtual space.

Мақалада тілдік тұлғаның сөйлеу әрекетінің ажырамас бір бөлігі саналатын айтылым үдерісі мен лексикон ерекшеліктері қарастырылды. Ділдің адам психологиясы мен сөйлеуіне әсері, керісінше, психология мен тілдің ділге әсері бар ма деген мәселелер анықталды. Ділдің психологиялық құбылыс ретінде әмбебап сипатта болатындығын, психика әрекетінде ұлт-ұлтқа ортақ жайттар басым екені, ал осыны тілмен жанастырғанда барып ұлттық ділдің ерекшеліктері байқалып отыратындығы айқындалды. Қалай десек те, психолингвистика тұрғысынан қарасақ, ділдік лексикон жеке адамдардың жалпы адамзат бөлшегі ретіндегі психикасына, жанның ішкі қимылына байланысты екендігі байқалды. Қарапайым түрде айтсақ, сөз саптау мен қабылдау әрекеті ұлт-ұлтқа ортақ. Оларды өзгешелейтін — болмысты бейнелеу үшін қолданылатын тіл болып шығады екен. Сонымен бірге, зерттеуде тілдік тұлғаның сөйлеу кезінде сөз мағынасын өзінің прагматикалық мақсатына сай қолдануына қатысты қырлары мен ерекшеліктеріне назар аударылған.

One of the topical issues of modern linguoconceptology is studying the specifics of concepts functioning in various discourses, such as political, economic, medical, artistic, etc. Such a study is based on the preliminary construction of the most characteristically complete model of the concept that serves as “an intra-linguistic standard of comparison” (Vorkachev). It serves as a basic semantic prototype reflecting the main definitional semes of the concept under consideration against the background of which the discursively conditioned specifics can be identified. In this article, the concept “book” is described as a significant element of the national language world image. Based on the analysis of lexicographic data and the main frame propositions, a semantic model of the concept is structured, the complex of its representatives in the Russian language is determined.

Дискурсология – қазақ тіл білімінде жаңа қалыптасқан ғылыми салалардың бірі. Қазақстандық зерттеушілер қатары бүгінде дискрустың анықтамасы, дискурс пен мәтін арақатынасы, дискурстың жанрлық түрлері туралы біраз зерттеулер жасады. Мақалада түрлі тілдердің ертегі дискурсындағы ұлттық таным мәселесі және ондағы ұлттық таным көрінісін нақты мысалдар арқылы талдайды. Авторлар ертегі дискурсындағы үштік мәселесін, яғни үш санына қатысты ұғымдарға мысалдар келтірген. Дискурстың бірден-бір тілдік бірлігі болатын ұлттық тіл  мәселесіне тоқталған. Ұлттық тілдің әрбір этнос аясындағы қарым-қатынастың ерекшеліктерін орнататындығын, этикеттің қалыпты моделін және толықтай сөйлеу мәнерін анықтайтындығын, әр халықтың өзіне тән мәдени коды жайлы сөз болады. Дискурс айналымында ұлттық таным кілт сөздерге байланады деген тұжырым жасайды. Сонымен қатар ертегі дискурсындағы эксплициттілік және имплициттілік мәселесі де қарастырылған. Ертегілерді ұлттық-мәдени элемент ретінде ала отырып, әр халықтың өзіне ғана тән бейнелеу образдарын мысалға келтірген. Олардың лингвомәдени және ұлттық танымдық сипатын анықтау бүкіл ұлттық дүниетанымның ерекшеліктерін нақты танып-білуге септігін тигізеді, сондықтан да ертегілерді танымдық тұрғыда зерттеу антропоөзектік парадигмада, тілді адаммен және оның әлемімен тығыз байланыста талдауды басшылыққа алу қажет деген қорытындыға келеді.

Мақалада К. Юнгтің Эго, Өздік /Самость/ Self архетипінің мәні, ұжымдық бейсаналықтың бір түрі болып саналатындығы зерттелді. Эго мен Өздік ақыл-ойдың үйлесім табуы адамның саналы өмір сүруіне негіз болса, ал Эгоның адамның Өздік ақылына бағынбай алға шығуы мен мендік, өзін-өзі пір тұту, атаққұмарлық, билікқұмарлық сияқты түрлі құмарлыққа салынуына жеткізетіні К. Юнг еңбектерін талдау барысында айқындалды. Абай шығармаларындағы Эго, Self архетипінің көрінісі мифопоэтикалық сипатқа ие екені ақын өлеңдерін талдау барысында анықталды. Сонымен қатар, әдебиеттану ғылымында миф, мифология және мифопоэтиканың өзіндік ерекшелігі және айырмашылығы зерттеуші  ғалымдар еңбектерінде сараланды. Мифопоэтиканы зерттеген Г.А. Токарева, С.М. Телегин еңбектеріндегі ғажайып образдардың табиғатындағы мифопоэтиканы көркем шығармадан анықтаудың жолдары мен тәсілдері қарастырылды. Абай шығармаларындағы «көңіл» ұғымының сан түрлі құбылған бейнесін зерттеу арқылы ақынның Эгосын тануға мүмкіндік туды.

Ағылшын тіліндегі түркі кірме сөздерінің бейімделуінің маңызды көрсеткіштерінің бірі оларды ағылшын тілінің түрлі (түсіндірме, этимологиялық, фразелогиялық) сөздіктерінде саралау, сондай-ақ оларды әртүрлі көркем шығармаларда пайдалану. Тілдік байланыстар лингвистикалық, мәдени және тарихи факторлардың өзара әрекеттестігінде байқалады және мәдениетаралық коммуникацияның маңызды процесі болып табылады. Тіл механизмі ретінде түрлі тілдерде белсенді қолданылатын түркі лексикалық элементтері ерекше назар аударуды талап етеді. Әртүрлі тілдерді салыстыру кірме сөздердің тілдің әмбебап фактісі екенін көрсетеді, оның тілдік мәні олардың әртүрлі тілдер жүйесіне кіруінің абсолюттік немесе салыстырмалы хронологиясын анықтауға мүмкіндік береді. Реципиент тілінің лексика-семантикалық жүйесімен тығыз байланысты түркі тілдері ену жолдары мен бейімделу дәрежесін көрсете отырып, ағылшын және басқа тілдердің тілдік бірліктерінің корпусын кеңейтеді. Бұл ретте тілдің лексикалық және фонетикалық әлеуетінің заңдылықтары есте сақталады. Түркі кірме сөздеріне тек түркі сөздері ғана емес, сонымен қатар араб және моңғол, парсы, татар, өзбек, қазақ тілдеріндегі лексикалық элементтер кіреді.
The progressing from “chaos to order” in the language system
Authors: Zhaparova T.Ye. , Shaibakova D.D. , Arikan A.
Published: January 2024

The article considers the development of a language, in which, as in an open system, chaos and its ordering in the future are established. New elements entering the language are adapted into it, the rules and behavior in language change. In this case, such a process is observed from the synergetics position, which shows that in an open environment, the encountering of energy and substance creates chaos, which should tend to order. An attempt has been made to understand how the correlation of chaos and order is resolved in a communicative environment. The relevance of the article lies in the analysis of new models of word formation in speech, linguistic changes resulting from the interaction of factors of external and internal order. Internal and external factors of language development are considered as a manifestation of the conditions for the organization and disorganization of the system. Chaos and ordering of movements in the language, control of a complex, selforganizing, dynamic system allow observing the impact on the communicative environment and the ability to prevent the arising of deviations in the language.
Twig-like middle cerebral artery as a variety of isolated middle cerebral artery disease with new vessel formation: illustrative case
Authors: Nakajima Hideki , Miyake Ryota , Iwaki Katsuma , Hongo Taku , Takasaki Morio , Fujimoto Yasuhiro
Published: January 2024

BACKGROUND

Twig-like middle cerebral artery (T-MCA) is reported as a rare vascular anomaly characterized by reconstitution of the M1 segment of the middle cerebral artery (MCA) by a plexiform network of small vessels. Although it is generally believed that the etiology of T-MCA is an embryological persistence, some investigators have suggested that T-MCA may be a secondary consequence. Here, the authors report a second case of de novo T-MCA formation and reconsider the concept of T-MCA in connection with isolated MCA disease.

OBSERVATIONS

A 40-year-old man’s brain magnetic resonance imaging (MRI) checkup showed moderate stenosis of the M1 segment of the left MCA. Annual MRI follow-up was planned, and when performed 1 year later, it showed occlusion of the M1 segment of the left MCA. Cerebral angiography revealed occlusion of that M1 segment with abnormal arterial networks. This case was diagnosed as de novo T-MCA. The patient has remained asymptomatic for 2 years.

LESSONS

The reports of de novo T-MCA indicate that acquired factors may be involved in the pathogenesis of T-MCA. We suggest that T-MCA should be defined as a variety of isolated MCA disease with new vessel formation.
Exuberant circumferential fibroproliferative neuromas in lipomatosis of nerve: a unifying theory. Illustrative case
Authors: Maldonado Andres A , Mahan Mark A , Carter Jodi M , Amrami Kimberly K , Marek Tomas , Spinner Robert J
Published: January 2024

BACKGROUND

Lipomatosis of nerve (LN) is a rare disorder characterized by the massive enlargement of peripheral nerves, frequently accompanied by generalized fibroadipose proliferation and skeletal overgrowth.

OBSERVATIONS

The authors have been routinely following a 20-year-old male for lipomatosis of median nerve at the wrist noted shortly after birth. He had undergone resection of the lesion accompanied by sural nerve grafting at another institution. Clinically, although his neurological loss of function has been stable, he has had continued soft tissue growth. Serial magnetic resonance imaging has revealed persistent LN proximal to the repair sites with evidence of fatty proliferation in the sural grafts and continued LN and fatty proliferation distally. There has been a progressive circumferential pattern of fibrosis around the proximal and distal suture lines, which has a similar radiological pattern to desmoid type fibromatosis (a pattern recently described in neuromuscular choristoma [NMC] desmoid-type fibromatosis).

LESSONS

Considering the similar reaction of nerve in both LN and NMC despite differing genetic cascades, the authors believe a unifying process occurs in both lesions. The pattern of circumferential fibroproliferation would be most consistent with neuron-mediated growth from unspecified trophic factors, supporting a previously reported a nerve-derived “inside-out mechanism.” The clinical consequences of this unifying process are presented.
Stereotactic radiosurgery for the treatment of a distant recurrence of ependymoma on the optic nerve: illustrative case
Authors: Orrego González Eduardo , Lopes M. Beatriz , Ramos Gabriel Anibal , Sheehan Jason P
Published: January 2024

BACKGROUND

Ependymomas rarely disseminate to other central nervous system areas distant from the original site. Stereotactic radiosurgery (SRS) provides high control rates for recurring ependymomas. The treatment of optic nerve tumors carries high morbidity, but SRS is an acceptable option to manage these cases to reduce risks.

OBSERVATIONS

The authors report the case of a 31-year-old male with a cervical spinal ependymoma who had a disseminated pattern of recurrence including the optic nerve after initial resection of the cervical lesion. The optic nerve tumor was treated with SRS, and the authors discuss the technical aspects of the treatment and its outcomes. At the last follow-up, the optic nerve tumor was controlled with SRS, and visual function was preserved.

LESSONS

High-grade ependymomas such as the one in the presented case can have unpredictable patterns of recurrence. SRS provides excellent control of the distant recurring ependymoma with a low complication profile given the location of the tumor in this case.
