Purpose : This systematic review examined evidence published 2000-2021 for occupational therapy interventions for adult Attention Deficit Hyperactivity Disorder (adult ADHD). Methods : In order to find out the studies on the effect occupational therapy intervention on individuals with adult ADHD, studies published from 2000 to February 2022 were searched on Google Academic Search. The keywords used were "adult ADHD" AND "Occupational therapy". A total of 785 studies were searched, and from these, 3 studies were selected based on the application of the selection and exclusion criteria. The included studies comprised of 1 Quasi-experimental design study(one group pre-post test) and 2 randomized controlled trials design studies. The included studies were analyzed in PICO(patients, intervention, comparison, outcomes). Results : As a result of analysing the subjects of the included studies, subjects diagnosed with adult ADHD or classified as high-risk group in Adult ADHD Self-Report Scale test, the number of subjects was 97, and the average age was about 33 years old. Occupational therapy intervention methods for adult ADHD include Tailored Intervention, Computerized Cognitive Training, and Cognitive-Functional Intervention. The Adult ADHD Self-Report Scale was the most used to check the symptoms of ADHD, and the COPM was used the most to measure the effects of occupational therapy interventions. The dependent variables of occupational therapy intervention were occupational performance, quality of life, executive function (behavioral regulation, metacognition), self-regulation function, stress management, and sustained attention. The effect of the intervention was statistically significant in 78.5% of the total. Conclusion : It is expected that the results of this study can be used as basic data for evidence-based practice for occupational therapists to apply adult ADHD interventions. In the field of occupational therapy in Korea, research on various interventions that can improve the occupational performance of adults ADHD should be conducted.

Comparative study on the effects of $H_2$ vs. $O_2$ plasma pretreatment of gate oxide on the degradation phenomenon of p-channel low-temperature polysilicon (LTPS) thin-film transistors (TFTs) were performed. After high drain current stress (HDCS) with $V_{gs}$ = $V_{ds}$, the p-channel TFTs pretreated by $O_2$ plasma showed increased immunity to the degradation of device characteristics such as threshold voltage and maximum field effect mobility because of the higher binding energy of Si-O bond than that of Si-H bond. The investigation of degradation phenomenon of these parameters with the applied power suggests that self-heating can be the major cause of degradation of polysilicon TFTs.

This is an quasi experimental study using nonequivalent pre-test post-test control design for the development of the CAI program and an analysis of its effects, for nursing college students to learn emergency patient triage. This program was developed from November, 2000 to middle of September, 2001 with the aid of curriculum design experts. The subjects of this study were 86 randomly sampled freshmen students of C nursing college in Ulsan. They were divided into 45 for the test group and 41 for the control group. The CAI program for the learning of the emergency patient triage has been developed on the basis of Merrill's Component display theory and Keller's ARCS theory and through the curriculum design process of Hannafin ＆ Peck. It has also been done with the use of Tool book 8.0, the multimedia righting tool. The experiment to verify the effect of the CAI program has been carried on from September, 20 to October, 8 2001. There were six hypotheses to accomplish the purpose of the study, and the analysis of the data was done with the use of SPSS/win program. As a result of this study, the author concluded that this CAI program is an effective mediation method to promote the learning accomplishment and learning motive for nursing college students. Therefore in the field of emergency nursing education, it would be possible to use this program as means for widening the possibility of self-learning and to promote individual learning of nursing college students.

We report here the results on N-acetyl-N'-methylamide of 4-fluoroproline (Ac-Flp-NHMe) calculated using the ab initio molecular orbital method with the self-consistent reaction field (SCRF) theory at the HF level with the 6-31+G(d) basis set to investigate the stereoelectronic effects on the conformational preference of proline depending on the cis/trans peptide bonds and down/up puckerings along the backbone torsion angle $\square$ in the gas phase, chloroform, and water. In the gas phase, all potential energy surfaces for Ac-Flp-NHMe are quite similar to those of Ac-Pro-NHMe, except that up-puckered conformations are more stabilized than down-puckered ones. In chloroform and water, polyproline structures become dominant, whose populations are larger than those of Ac-Pro-NHMe. In chloroform and water, the populations of polyproline II (i.e., tF conformations) are quite similar to each other, but those of polyproline I (i.e., cF conformations) are larger by 5％ in water than in chloroform. In particular, all cis populations for Ac-Flp-NHMe in the gas phase, chloroform, and water are decreased than those of Ac-Pro-NHMe.

This paper presents a radiation-hardened-by-design preamplifier that utilizes a self-compensation technique with a charge-sensitive amplifier (CSA) and replica for total ionizing dose (TID) effects. The CSA consists of an operational amplifier (OPAMP) with a 6-bit binary weighted current source (BWCS) and feedback network. The replica circuit is utilized to compensate for the TID effects of the CSA. Two comparators can detect the operating point of the replica OPAMP and generate appropriate signals to control the switches of the BWCS. The proposed preamplifier was fabricated using a general-purpose complementary metal-oxide-silicon field effect transistor 0.18 ㎛ process and verified through a test up to 230 kGy (SiO₂) at a rate of 10.46 kGy (SiO₂)/h. The code of the BWCS control circuit varied with the total radiation dose. During the verification test, the initial value of the digital code was 39, and a final value of 30 was observed. Furthermore, the preamplifier output exhibited a maximum variation error of 2.39%, while the maximum rise-time error was 1.96%. A minimum signal-to-noise ratio of 49.64 dB was measured.

In this paper, we explore the electrical properties and high-frequency performance of carbon nanotube field-effect transistors (CNTFETs), based on the non-equilibrium Green's functions (NEGF) solved self - consistently with Poisson's equations. The calculated results show that CNTFETs exhibit superior performance compared with graphene nanoribbon field-effect transistors (GNRFETs), such as better control ability of the gate on the channel, higher drive current with lower subthreshold leakage current, and lower subthreshold-swing (SS). Due to larger band-structure-limited velocity in CNTFETs, ballistic CNTFETs present better high-frequency performance limit than that of Si MOSFETs. The parameter effects of CNTFETs are also investigated. In addition, to enhance the immunity against short - channel effects (SCE), hetero - material - gate CNTFETs (HMG-CNTFETs) have been proposed, and we present a detailed numerical simulation to analyze the performances of scaling down, and conclude that HMG-CNTFETs can meet the ITRS'10 requirements better than CNTs.

The milling effects of a precursor $Y_2BaCuO_5$ (Y211) powder having 1 wt.% $CeO_2$ on the microstructure and critical current density ($J_c$) of liquid infiltration growth (LIG) processed $YBa_2Cu_3O_{7-y}$ (Y-123) bulk superconductors were investigated. The microstructure analysis revealed that the Y211 size in the final Y-123 products decreased with increasing the milling time and a relatively high density and uniform distribution of Y211 inclusions were observed in the sample prepared using 8 h milled powder. However, the unexpected Y211 particles coarsening was observed from the 4 h milled sample which was further increased for 10 h milled sample. Critical current density ($J_c$) of the LIG processed Y-123 bulk superconductors was found to be dependent on the milling time of the Y211 precursor powder. The $J_c$ increased with the increase of milling time and reached up to a maximum at 8 h in the self field while 10 h milled sample showed lower $J_c$ at the same field which might be due to the exaggerated growth and non-uniform distribution of Y211 particles.
