A study on the factors influencing the changes in the scale of Japanese students studying abroad since the normalization of diplomatic relations between China and Japan
Authors: WANG Zhao
Published: January 2024

In 2017, China has become Asia's largest study destination country, but at the same time, the number of international students from Japan has been decreasing year by year. Understanding the factors that influence Japanese students' choice of study abroad destination is critical to understanding the reasons for this trend. This article takes Japanese international students as the research objects, starting from the development of the number of Japanese international students since the normalization of diplomatic relations between China and Japan, and focusing on analyzing the reasons behind the decrease in the number of Japanese international students. It has been found that Sino-Japanese diplomatic relations, study-abroad policies, Sino-Japanese trade relations, costs of studying abroad, expected benefits, rankings of Chinese universities, number of institutions, number of Confucius Institutes and courses, and total exports of Chinese cultural products are important factors affecting the changes in the number of Japanese students studying abroad. This study also provides suggestions to promote the growth of Japanese students studying abroad, and improve the quality and efficiency of China's overseas education.

Authors: ZHAO Dandan
Published: January 2024

Biochemistry is a comprehensive discipline involving structure, function and interrelationships of life at the molecular level. Globally, more and more educational institutions are using bilingual teaching as a means to improve students' language ability and subject level. However, in the bilingual teaching of biochemistry, the integration of ideological and political education is often ignored, which leads to the lack of profound understanding of ideology and morality while learning academic knowledge. Therefore, the study of how to effectively integrate ideological and political education into the bilingual teaching of biochemistry has become an urgent problem to be solved. This paper aims to explore how to effectively integrate ideological and political education in bilingual teaching to improve students' academic and ideological education. The paper first analyzes the current situation and challenges of the bilingual biochemistry teaching, and then proposes a series of innovative practical strategies to strengthen the application of ideological and political education in the biochemistry teaching. Finally, the empirical study and case analysis demonstrate the effectiveness and utility of these strategies.

An analysis of eco-translation from the perspective of culturally-loaded words
Authors: WEI Dandan
Published: January 2024

In recent years, the discussion on cultural translation perspectives has gradually replaced the simple language analysis and has gained more attention in translation studies. With profound cultural connotations and distinct cultural personalities, culturally-loaded words are often regarded as the representatives of the soft power of a country. However, since there exist cultural differences between different languages, the translation of culturally-loaded words remains a major difficulty in the translation process. This paper aims to explore the translation of culturally-loaded words in terms of three dimensions of ecological translation so as to achieve the translation accuracy as much as possible. The study shows that eco-translation does play a significant role in the translation of culturally-loaded words.

The effects of creativity and crystallized intelligence on metaphor comprehension
Authors: CHEN Yue
Published: January 2024

The nature of the cognitive processes involved in metaphor comprehension has spurred ongoing debate, particularly concerning the relative contributions of general analogy versus language-specific categorization. One prominent proposal posits that metaphor comprehension necessitates analogical reasoning to establish a relationship between the target and the source. An alternative perspective posits that metaphors can be interpreted as categorization statements. This paper adopts an individual-differences approach to probe metaphor comprehension, encompassing both literary and non-literary metaphors. The research conducted a metaphor-comprehension study involving college students, measuring both creativity (using the Chinese Remote Association Test) and crystallized verbal intelligence (using the verbal subscale of the Wechsler Adult Intelligence Scale). The research findings revealed distinct predictive relationships between each measure and metaphor comprehension. Specifically, it had been observed that crystallized intelligence significantly influences comprehension across a wide spectrum of metaphor types, encompassing both literary and non-literary examples. Conversely, individual differences in creativity predominantly impact the comprehension of more cognitively intricate metaphors, notably those originating from literary sources.

Стаття присвячена аналізу окремих законодавчих ініціатив щодо удосконалення кримінального-правового забезпечення свободи від втручання в приватне життя людини відповідно до проєкту Закону України «Про внесення змін до Кримінального кодексу України щодо забезпечення свободи від втручання в приватне життя людини» № 9623 від 18.08.2023 р. Висловлено критичні зауваження з приводу необґрунтованості позиції розробників законопроєкту щодо втрати відповідними діяннями суспільної небезпечності. Однією з базових підстав декриміналізації діянь слід вважати саме відповідні зміни в структурі суспільної моралі. Наголошено, що утримання законодавчих меж, що позначають морально-правову позицію держави на неприпустимість розбещення, утримання високого формату людської естетики та етики – це є, перш за все, питанням про гідність, а не про поширеність, доступність, економічну привабливість. Для України ж питання гідності є центруючими останні десять років, адже саме гідність визначає суб’єктність, правову, політичну, цивілізаційну. Сформовано низку зауважень та пропозицій щодо ознак об’єктивної сторони складу злочину, передбаченого ст. 301 КК України de lege ferenda.

МАРОДЕРСТВО: У ПОШУКАХ РОЗУМІННЯ ЗМІСТУ ДІЯННЯ
Authors: ЛИЗОГУБ Я.Г.
Published: January 2024

Статтю присвячено проблемі законодавчого визначення окремих складових такого злочину, як мародерство, відповідальність за яке встановлено у ст. 432 Кримінального кодексу України. Подібне дослідження виконане як на тлі етимологічного походження та семантичного значення зазначеного явища, так і з урахуванням законодавчих підходів до його розуміння у кримінальних кодексах деяких зарубіжних країн. Звернено увагу на наявну звуженість змісту мародерства в чинному кримінальному законі, показано й обґрунтовано доцільність включення до такого суспільно небезпечного діяння й інших видів поведінки, що з логічної точки зору послідовно відтворюють мародерство, як його наразі визначає Кримінальний кодекс України. Наголошено, що зміст чинної ст. 432 Кримінального кодексу України створює певні перепони у правильному розумінні визначеного нею діяння, особливо на тлі включення фактично притаманних йому атрибутів до змісту деяких інших кримінальних правопорушень. Висловлено думку про сумнівну припустимість такого підходу.
СУТНІСТЬ ТА КРИМІНАЛІСТИЧНА КЛАСИФІКАЦІЯ СЕКСУАЛЬНОГО НАСИЛЬСТВА В УМОВАХ ВІЙНИ
Authors: НАУМКІН О.О.
Published: January 2024

Запропоновано авторське трактування поняття «сексуальне насильство» як умисні злочинні дії сексуального характеру за відношенням до особи потерпілої, які вчиняються проти її волі та порушують суспільні відносини у сфері захисту фізичного та (або) психологічного здоров’я громадян. Метою такого протиправного впливу є задоволення власного статевого бажання чи потягу неприроднім шляхом без фізіологічного акту. Виокремлено наступні критерії криміналістичної класифікації сексуального насильства в умовах війни: за кількістю учасників-осіб злочинців; за формою насильницьких дій сексуального характеру (фізичне або так зване «біологічне» насильство; психологічне або так зване «ментальне» насильство); за соціальним статусом особи потерпілого (сексуальне насильство за відношенням до подружжя (в т.ч. близьких осіб або членів сім’ї); сексуальне насильство за відношенням до особи, яка виконує службовий, професійний або громадський обов’язок; сексуальне насильство за відношенням до жінки, яка завідомо для винного перебувала у стані вагітності); за віком особи потерпілого; за детермінованістю соціального зв’язку між особами потерпілого та злочинця (сексуальне насильство щодо знайомої особи потерпілого; сексуальне насильство щодо незнайомої особи потерпілого); за структурою механізму злочинної діяльності (повно структурні або прості); за місцем реалізації злочинного задуму; за часом (короткотривале сексуальне насильство; довготривале сексуальне насильство).

У статті здійснений концептуальний аналіз проблеми теології у понад 50-ти працях українських авторів. Виявлено, що постмодерна доба зумовлена багатьма суперечками між вірою і розумом у ключі того, чи протиставляти філософію і теологію. За позицією католицького мислителя Г. У. фон Бальтазара, «без філософії немає богослов’я», якщо йдеться про осягнення серйозних рівнів теологічного мислення/богослов’я, з чим не можемо погодитися, адже, можливо, доля й Константинополя (Святої Софії) склалась би інакше та не піддалась би магометянській вірі, якщо б філософська складова Царгорода не заполонила церковне/духовне життя. Саме тому так важливо берегти чистоту нашої загальнодержавної, у більшості своїй православної, віри. За висловлюваннями православного старчества, справжній богослов – той, хто молиться/вміє правильно молитися Богові/правильно славити Його. За словами Силуана Афонського, «молитись, що кров проливати», і лише той зрозуміє це, хто щодня молиться за ближніх своїх. Тоді відкриваються такі рівні і стани всього невідомого/неймовірного, що жодні книги і міркування не здатні вмістити. Тим самим, глибинні духовні стани моління дають відкриття/відчуття Духу Божого, коли серце, розум, душа з’єднуються воєдино у відкритті неосяжного.

Протидія злочинності – один із ключових напрямів діяльності міжнародних і національних правоохоронних органів, громадських організацій тощо. Такі засади закріплені у положеннях чинного законодавства, що є спеціальними у контексті визначення повноважень органів правоохоронних. Цими ж законодавчими актами визначено і напрями взаємодії правоохоронних органів із населенням. Задля подальшої розбудови громадянського суспільства, створення гармонійних підвалин для функціонування його формалізованих структур, важливим є залучення їх до діяльності органів державного сектору, серед яких важливу роль в окреслених процесах відіграє сектор безпеки й оборони. Одним із важливих і актуальних наразі напрямів діяльності останніх є протидія торгівлі людьми. Ураховуючи це та виходячи з реалій сьогодення, метою дослідження стало визначення перспектив використання можливостей інститутів громадянського суспільства у попередженні та запобіганні торгівлі людьми, відповідно до апробованих міжнародно-правових стандартів, окреслення перспектив їх використання при формуванні державної політики України та впровадження в правозастосовну практику національних правоохоронних органів.

Акцентовано увагу на тому, що податки і збори - це обов'язкові платежі, які належить сплачувати фізичним та юридичним особам у встановленому законодавством порядку до бюджету держави або місцевого самоврядування, з метою забезпечення фінансових потреб держави, реалізації її соціально-економічних програм і проектів.

Доведено, що митний платіж - це обов’язковий платіж, який сплачує фізична або юридична особа при переміщенні товарів через митний кордон країни, або при здійсненні інших митних операцій, таких як імпорт, експорт, транзит тощо.

Констатовано, що митні платежі займають особливе місце у системі податків і зборів України. Зазначене пояснюється тим, що митні платежі складають не лише велику долю надходжень до державного бюджету, а й виступають важливим інструментом регулювання зовнішньоекономічної діяльності країни. Окрім того, безспірним є той факт, що митні платежі є важливим засобом боротьби з контрабандою та незаконним переміщенням товарів через державний кордон.

Utilities are one of the supporting processes in a factory, consisting of units providing water, steam, electricity, fuel procurement, compressed air, and wastewater treatment. Wastewater from industrial processes contains: toxic pollutants, organic and inorganic materials, also other industrial materials are toxic, mutagenic, and carcinogenic, so treatment is needed to overcome this. Wastewater treatment can use coagulation and flocculation methods. Coagulation is the process of adding chemicals to the water that causes the separation of particles to destabilize the particles and allow them to adhere to other particles (to remove) in the following process. Factors that can affect the success of the coagulation process include the type of coagulant used, coagulant dose, moving process, and pH. Meanwhile, flocculation removes water turbidity by collecting small particles into larger particles with the addition of chemical flocculants. The flocculants are divided into two, perikinetic flocculation and optokinetic flocculation. This article aims to determine the effectiveness of wastewater treatment in the chemical industry using the coagulation-flocculation method. The coagulation-flocculation process can reduce pollution of the aquatic environment so as not to aggravate cases of environmental pollution.

Rancasari Subdistrict is located in Bandung City, comprises four urban villages, encompassing 0,19 km2 with six blocks of light slum areas. Slum areas are areas that tend to have more vulnerable environmental conditions due to the minimal availability of environmental infrastructure, one of which is sanitation facilities. Based on this, Rancasari subdistrict needs to determine the type of domestic wastewater management system service and priority service areas. Determination of the service type of domestic wastewater management system is determined based on Attachment 1 of Regulation of the Minister of Public Works and Public Housing Number 4 of 2017, while priority areas are determined based on Bandung City Regional Regulation Number 5 of 2022, Regional Regulations Bandung City Number 10 of 2015, and the area of slum settlements in each village. Rancasari Subdistrict is suitable for on-site system, while the main priority area is Manjahlega Village, then Mekarjaya, Derwati, and Cipamokolan. It is necessary to develop domestic wastewater management system facilities in the main priority area in the form of development of existing communal septic tanks and communal wastewater treatment facility, as well as the closure of piped domestic wastewater disposal facility leading to the Cidurian River to stop open defecation.

Organophosphate (OP) pesticides are one of the pesticides with the widest and most widespread use in the world. Excessive use of agricultural land can have a negative impact on humans and the environment. One of the alternative methods that can be used to reduce OP in the environment is adsorption using activated carbon (KA). KA has been proven to be able to deal with various hazardous substances in the environment, including pesticides. This paper aims to look at KA’s capabilities and obstacles in adsorbing OP. The results of this review show that the adsorption ability of KA on OP depends on environmental temperature and pH. At optimum temperature, OP removal can reach 99.3%, while at optimum pH, KA’s adsorption capacity can be higher up to 68.15 mg/g. Other factors such as environmental characteristics, characteristics of the train used, and target adsorbate (OP) are still challenges for future research before its application in the agricultural environment.

CV. Hagia Mitra Mandiri is a company that distributes black queen bee honey products. Problems faced by CV. Hagia Mitra Mandiri in the distribution of its products, namely that the company has not yet planned product delivery routes to various customers of bitter black queen bee honey in the Jakarta, Bogor, Depok, Bekasi and Karawang areas. As a result, product delivery routes often exceed customer working hours, which can make delivery schedules less than optimal in terms of distance, travel time and delivery costs. This research aims to design the route that each vehicle must take according to the user's working hours, with the aim of optimizing the total travel distance. The method used is the sequential insertion algorithm method to solve the Vehicle Routing Problem with Time Windows problem model. The sequential insertion method is used to plan proposed distribution routes by considering travel distance, travel time and transportation costs. The research results show that there are differences in the proposed route from the initial route. The proposed route resulting from the calculation of the sequential insertion algorithm method produces the best distance, namely 307 km with a savings ratio of 18.13%, a comparison of total transportation cost savings of Rp. 58,758 and the difference in fuel usage is 7.55 liters. The total travel time is 667 minutes and the total travel time ratio is 9.01%.

Technological advances mean that steel production continues to be developed with better raw materials. Carbon steel is the one of the metals that is widely used in producing machining equipment, but it requires adjustment to the hardness and ductility properties of the steel must be heat treated to obtain properties according to its use from soft to hard. This research aims to determine the effect of cooling media in the quenching process and tempering process on hardness, tensile strength and microstructure. The variations used are variations in temperature and variations in water and oil quenching cooling media. The research method used was the experimental method, using descriptive statistical data analysis techniques, then hardness testing was carried out using the microvickers method, tensile testing, and microstructure observation. The research result showed that the highest hardness value was at a temperature variation of 900°C for the water-cooling medium with a hardness value of 490,1 VHN. The highest average tensile strength was produced by specimens with a heating temperature of 900°C with water cooling media, namely 1051,2 N/mm2. And the result of the microstructure test shows structural changes, namely the formation of a martensite structure due to the process of heating the austenite and the cooling it quickly.

Metal materials can be used in renewable energy with future technologies for safe hydrogen storage media. Metal hydrides are a safe and effective way to store hydrogen for vehicle applications. Due to its high capacity in mass and volume for hydrogen storage, metal hydrides are currently the subject of intense research. However, the thermodynamic properties of magnesium hydride (MgH2) produce moderate temperatures, during the hydrogen desorption reaction reaching about 3000C to 4150C at 1 bar. The thermodynamic properties of high MgH2 cause the desorption temperature to also increase. The enthalpy produces high desorption (about 74 KJ/mol H2). In addition, the process of transforming magnesium into magnesium hydride takes a long time, (for 60 hours). From the results of the study, iron sand, a material from nature, which has been extracted into Fe3O4 powder, is used as a catalyst. This is done to improve the absorption properties and reaction kinetics of hydrogen storage materials based on MgH2, namely magnetite Fe3O4. The yield of Magnetite Extraction (Fe3O4) from iron sand is 85% purity, compared to the purity of Iron sand before extraction, which is 81%. Mechanical alloying methods are used to process MgH2-Fe3O4 samples, with different milling times and different catalysts.

The production process of natural indigo dye from the Strobilanthes cusia plant has solid leaf waste as a by-product from maceration residue. This waste can be used to make solid organic fertilizer. This research aims to determine the effective concentration of adding local microorganism (MOL) of kepok banana peel and EM4 to bioactivators obtain good quality compost. Composting was carried out aerobically with variations in the concentration ratio of kepok banana peel MOL and EM4 bioactivators of 1%, 2%, 3%, 4% and 5% respectively. Fertilizer quality is determined by testing the C/N ratio parameter using the Walkey & Black (C-Organic) and Kjeldahl (N-Total) methods. Color, texture and odor tests were carried out organoleptically by 5 panelists. The results showed that in the concentration range of 1-5%, the MOL kepok banana peel bioactivator was more effective than EM4, as evidenced by the lower C/N ratio of the compost. The best product was obtained from the composting process with 5% MOL kepok banana peel bioactivator with a C/N ratio of 50.04%, water content of 48.74%, blackish brown color, very crumbly texture and an earthy smell. This result does not meet the standards for compost quality according to SNI 19-7030-2004, but the physical parameters such as color, texture, odor and water content meet the standards, namely blackish brown color, very crumbly texture and smells like soil.
