Tomato powdery mildew, fruit rot, and twig blight are all managed with Deltamethrin. Its residues could still be present in the crops, posing a health risk. The pesticide residue analysis, dissipation rate, and safety assessments were thus examined in green tomatoes. The analytical method for residue analysis was validated according to international standards. Tomato fruits and soil were used to study the dissipation of Deltamethrin 100 EC (11% w/w) at 12.5 g a.i ha⁻¹ for the recommended dose (RD) and 25.0 g a.i ha⁻¹ for the double of the recommended dose (DD). Ethyl acetate was used to extract residues from tomato fruit, and PSA and magnesium sulphate were used for cleanup.The fruits had recoveries ranging from 83% to 93% and the soil sample from 81.67% to 89.6%, with the limit of detection (LOQ) estimated at 0.01 mg kg⁻¹. The matrix effect (ME) was calculated to be less than 20% for the tomato fruits and the soil.Half-lives for RD and DD were 1.95 and 1.84 days, respectively. All sampling days for both doses had dietary exposures of residues below the maximum permissible intake (MPI) of 0.16 mg person⁻¹ day⁻¹. The most effective method of decontaminating tomato residue containing Deltamethrin is blanching.

This research was conducted with the aim of developing indexes for diagnosis of balanced personnel levels in Korean Public Offices through Analytic Hierachy Process (AHP). The research found that 62.3% of ‘structural improvement’ and 37.7% of ‘inclusive organizational culture’ were weighted in large classification items. In the middle classification items, it was found weights of 27.5% for ‘gender equality’, 23.5% for ‘disabled’, 16.2% for ‘science and engineering’, 17.7% for ‘regional talent’, and 15.2% for ‘social integrated type’. In the small classification items, 9.4% of ‘employment rate of social integrated talent’, 5.3% of ‘the percentage of grade 7 and 9 selection of regional talent’ and 5% of ‘the percentage of women at the head of a department level’ were shown as important evaluation indicators. In addition, the ‘inclusive organizational culture’ was derived by allocating weights of 9.45% each for four areas: fairness, disclosure, cooperation and support. As above, this research constructs items of the balanced personnel index through prior research and designs detailed indexes. However, it is meaningful that surveys and others have confirmed the usefulness of the balanced personnel index, which will contribute to the achievement of balanced personnel objectives in public offices.

We examine the role of the North Aceh Government in implementing the Law on the Governing of Aceh (LoGA) as a legal structure in development policy. As a symbol of peace, the LoGA is a reference for accelerating development to alleviate poverty, including North Aceh as a conflict region. However, until now, the area remains the poorest in the province of Aceh. This research used descriptive qualitative methods, evaluating the local government’s performance as policymakers based on the Law by reconstructing policy theory (Easton) and legal system (Friedman). Our findings indicated that the local government needed help implementing LoGA to form development policies to solve poverty. This research suggested the importance of providing legal certainty in the distribution of authority, capacity building, and strengthening of political will for local government conducting its role.

English writing is an important output skill cultivated in college English courses. And in the age of informationization, college English writing teaching relies on the support of information technology. In order to cope with the solution of this dilemma, Production-Oriented Approach(POA) proposes Teacher-Student Collaborative Assessment (TSCA), which creates a new form of assessment. Through TSCA, teachers can not only alleviate the heavy teaching load, but also fully tap the network resources to efficiently use students' time before, during and after class to maximize and optimize the teaching effect. In this paper, the teaching concept of TSCA is used to conduct writing teaching experiments, to study and analyze the writing ability of students who write effectively, so as to provide insights for the practice of English writing teaching.
