        This study critically examines the integration of ILO Convention C111 into Vietnamese labour law, specifically examining its impact on sex-based discrimination. Employing feminist legal methodology, it assesses the reflection of the Convention’s anti-discrimination principles in national legislation and their effectiveness in promoting workplace gender equality in Vietnam. Preliminary findings suggest that, despite the Convention’s influence, there are significant obstacles to the full achievement of its objectives, largely due to socio-cultural and economic factors. The paper underscores the practical challenges of aligning the international labour standards with local laws preventing the implementation of C111’s provisions in combating gender-based discrimination in an employment setting. It argues that achieving true gender equality in employment transcends the simple adoption of international norms; it necessitates a holistic and profound approach. These insights are crucial for enhancing labour laws so as to foster genuine gender equality and emphasising the importance of practical implementation alongside the harmonisation of international standards.

        본 논문은 회분식 반응기에서 습식 산화법으로 합성한 칼륨 페레이트(VI)에 의한 난분해성 아조 염료Reactive Black 5의 분해 과정을 연구하는 것을 목적으로 한다. 수용액에서 RB5의 분해는 pH, Ferrate (VI) 투입량, 초기 농도, 수용액 온도 등 다양한 변수의 조건에서 연구되었다. RB5 경우에는 최대 분해 효율은 pH 7.0에서 63.2%가 달성되었으며, 이 실험 조건에서 얻은 kapp 값은 190.49 M-1s-1 으로 나타났다. 온도 또한 가장 중요한 매개 변수 중 하나로 연구되었으며, 그 결과로부터 온도(45°C까지)를 증가시키면 페레이트(VI)에 의한 아조 화합물 염료의 분해 효율이 증가하고, 온도가 45°C를 초과하면 분해 효율이 저하되는 것으로 나타났다.

        해사노동협약은 선원 인권 보호에 있어 전 세계적으로 성공적인 성과로서 국제노동기구에서 채택하였다. 특히, 이 협약의 선원근로계약 규정은 선원에게 양질의 근로와 생활 환경을 보장하기 위한 규정으로서 해사노동협약의 핵심으 로 인정되고 있다. 이러한 규정에도 불구하고 많은 회원국은 자국의 법률 시스 템에 핵심 규정을 완전히 반영하지 못하거나 실질적인 이행을 하지 못하고 있 는 상황이다. 특히 대표적인 선원 공급국이자 개발도상국인 베트남은 더욱 어 려운 실정이다. 따라서 이 논문에서는 해사노동협약의 선원근로계약에 관한 규 정을 중심으로 비교법적 연구 방법론을 통해 베트남 법제도의 차이를 분석하 고, 나아가 대표적인 해운 선진국인 대한민국의 선원법을 비교하여 베트남 법 제도의 문제점을 분석하고자 한다. 이를 통해 베트남의 해사노동협약 이행을 증진하기 위한 개선방안에 대해 논의하고자 한다.

        Recently, the occurrence of the fall webworm, one of the foreign invasive pests, is rapidly increasing due to the increase in average annual temperature due to global climate changes. In this study, we are presenting diverse eco-friendly technologies to control the fall webworm. (Grant No. PJ014845032023).

        We present a novel method that can enhance the detection success rate of interstellar objects. Interstellarobjects are objects that are not gravitationally bound to our solar system and thus are believed to haveoriginated from other planetary systems. Since the nding of two interstellar objects, 1l/`Oumuamua in2017 and 2l/Borisov in 2019, much attention has been paid to nding new interstellar objects. In thispaper, we propose the use of Heliospheric Imagers (HIs) for the survey of interstellar objects. In particular,we show HI data taken from Solar TErrestrial RElation Observatory/Sun Earth Connection Coronal andHeliospheric Investigation and demonstrate their ability to detect `Oumuamua-like interstellar objects. HIs are designed to monitor and study space weather by observing the solar wind traveling throughinterplanetary space. HIs provide the day-side observations and thus it can dramatically enlarge theobservable sky range when combined with the traditional night-side observations. In this paper, we rstreview previous methods for detecting interstellar objects and demonstrate that HIs can be used for thesurvey of interstellar objects.

        This study uses first-principles calculations to investigate the mechanical properties and effect of strain on the electronic properties of the 2D material 1H-PbX2 (X: S, Se). Firstly, the stability of the 1H Pb-dichalcogenide structures was evaluated using Born’s criteria. The obtained results show that the 1H-PbS2 material possesses the greatest ideal strength of 3.48 N/m, with 3.68 N/m for 1H-PbSe2 in biaxial strain. In addition, 1H-PbS2 and 1H-PbSe2 are direct semiconductors at equilibrium with band gaps of 2.30 eV and 1.90 eV, respectively. The band gap was investigated and remained almost unchanged under the strain εxx but altered significantly at strains εyy and εbia. At the fracture strain in the biaxial direction (19 %), the band gap of 1H-PbS2 decreases about 60 %, and that of 1H-PbSe2 decreases about 50 %. 1H-PbS2 and 1H-PbSe2 can convert from direct to indirect semiconductor under the strain εyy. Our findings reveal that the two structures have significant potential for application in nanoelectronic devices.

        In this study, graphene oxide (GO) was synthesized by the improved Hummers’ method. The degree of oxidation from graphite (Gi) to GO was determined through interlayer spacing calculated from X–ray diffraction. Besides, the effect of KMnO4: Gi ratios (X1), H2SO4 volume (X2), oxidation temperature (X3), oxidation time of stage 1 (X4), and oxidation time of stage 2 (X5) was screened by the Plackett–Burman model. The simultaneous impact of three factors that influenced the degree of oxidation (X1, X2, and X3) was studied by the Box–Behnken experimental model of response surface methodology to achieve suitable conditions for the GO synthesis process. The characterization of GO product was investigated via the modern analytical methods: X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy, UV–Vis spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and atomic force microscopy. Inaddition, the study was also carried out on a pilot scale for orientation in industrial application with the yield of 14 g/batch.

        Enhancing the capacitive deionization performance requires the inner structure expansion of porous activated carbon to facilitate the charge storage and electrolyte penetration. This work aimed to modify the porosity of coconut-shell activated carbon (AC) through CO2 activation at high temperature. The electrochemical performance of CO2- activated AC electrodes was evaluated by cyclic voltammetry, charge/discharge test and electrochemical impedance spectroscopy, which exhibited that AC-800 had the superior performance with the highest capacitance of 112 F/g at the rate of 0.1 A/g and could operate for up to 4000 cycles. Furthermore, in the capacitive deionization, AC-800 showed salt removal of 9.15 mg/g with a high absorption rate of 2.8 mg/g min and Ni(II) removal of 5.32 mg/g with a rate close to 1 mg/g.min. The results promote the potential application of CO2- activated AC for desalination as well as Ni-removal through capacitance deionization (CDI) technology.
