Objective: The current body of evidence lacks clarity regarding the comparative efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) as minimally invasive treatments for benign thyroid nodules. The primary objective of this study is to clarify these concerns. Materials and Methods: A comprehensive search was conducted using the Cochrane Library, Scopus, Europe PMC, and Medline databases until October 10th, 2023, using a combination of relevant keywords. This study incorporated literature that compared RFA and MWA for benign thyroid nodules. The primary outcome was the volume reduction ratio (VRR) from baseline to follow-up. Secondary outcomes were symptom score, cosmetic score, ablation time, major complications rate, hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. We used Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool to assess the risk of bias in the included studies. We employed random effects models to analyze the standardized mean difference (SMD) and odds ratio for the presentation of outcomes. Results: Nine studies with 2707 nodules were included. The results of our meta-analysis indicated similar efficacy between RFA and MWA in terms of VRR during the 1 (SMD 0.06; 95% confidence interval [CI]: -0.13 to 0.26; P = 0.52) and 3 (SMD 0.11; 95% CI: -0.03 to 0.25; P = 0.12) months of follow-up. VRR was significantly higher in RFA than in MWA at the 6 (SMD 0.25; 95% CI: 0.06-0.43; P = 0.008) and 12 month of follow-up (SMD 0.38; 95% CI: 0.17 to 0.59; P < 0.001). There were no significant differences between RFA and MWA in symptom scores, cosmetic scores, or the incidence of complications, including hemorrhage, hoarseness, skin burn, cough, and sympathetic nerve injury. Conclusion: RFA showed a higher VRR than MWA at 6 and 12-month follow-ups, with a comparable safety profile.

This paper compared and reviewed the poetic theories and Chinese poems of the Korean author Kim Chang Heup and his Japanese counterpart, Kan Chazan. Kim Chang Heup and Kan Chazan shared largely the same opinions on poetry, and both rejected archaism. First, they did not just copy High Tang poetry. Instead, they focused on the (sometimes trivial) scenery right in front of them, and described the calm feelings evoked by what they had seen. They also adopted a sincere tone, instead of an exaggerated one, because both believed that poetry should be realistic. However the differences between the two poets are also noteworthy. Kim Chang Heup claimed that feelings and scenery meet each other within a literary work through Natural Law, and the linguistic expressions that mediate the two are philosophical in nature. However, Kan Chazan did not use Natural Law as a medium between feelings and scenery. Instead the Japanese writer said the ideal poetical composition comes from a close observation and detailed description of scenery. In sum, while Kim Chang Heup continued to express reason through scenery, Kan Chazan did not go further than depicting the scenery itself. In addition, Kim Chang Heup believed poetry was not only a representation of Natural Law, but also a high-level linguistic activity that conveys a poetic concern about national politics. As a sadaebu (scholar-gentry), he held literature in high esteem because he thought that literature could achieve important outcomes. On the other hand, Kan Chazan regarded it as a form of entertainment, thereby insisting literature had its own territory that is separate from that of philosophy or politics. In other words, whereas Kim Chang Heup considered literature as something close to a form of learning, Kan Chazan viewed it as art. One might wonder whether the poetics of Kim Chang Heup and Kan Chazan reflect their individual accomplishments, or if the characteristics of Chinese poetry that Korean and Japanese poets had long sought after had finally surfaced in these two writers. This paper argued that the two authors' poetics represent characteristics of Chinese poetry in Korea and Japan, or general characteristics of Korean and Japanese literatures in a wider sense. Their request to depict actual scenery in a unique way, free from the ideal model of literature, must have facilitated an outward materialization of Korean and Japanese literary characteristics that had developed over a long time.

The visual humor can be regarded as an original source for creative ideation. There are several types of humor. for example,'wit, satire, irony and so on. These can be motivations of developing an up-to-date idea. Wit differs from most humor in being purely intellectual, rather than relying on incongruities that come up naturally in many situations. The humor of words contains pun, hyperbole, repetition, and comparison or contrast. Especially in case of pun, it can be most important type of humor for making analytical and humorous effects visually. Pun, meaning the humor of double meaning, furnish us with much of our humor. The concept of pun is the most valuable for creating the visual humor by substituting, combining and manipulating symbols. There are essentially three distinct categories of puns : the literal pun, the suggestive pun, and the comparative pun. All types of puns belong to one of these three groups. The definitions are simple to understand and easy to apply for creating the visual humor, In order to develop a better conceptual model, (this researcher) reexamine the concept of humor, the relationship of humor to various types of message processing, and the relationship of humor to various aspects of message. This thesis. is primarily concerned with basic theories of humor such as concepts of humor, types of humor and analysis of humor. And this contains the research of humor's communications effects and theory of humor response with literature reviews. Modem theories of humor response generally fall into three major schools : Incongruity theories, Superiority theories and Arousal (Relief theories. Together these three approaches address the cognitive-perceptual, affective-evaluative and psycho-dynamic dimensions of a subject's humor response. The literature research of humor and humor response theory in communications and visual communications can help the visual application of humor concepts and usefulness of visual humor appeals. This research agreed that the humor and visual humor must be very effective at being as a means for the advertising expression, not for the purpose itself. In addition, this research is aimed at studying significations and usefulness of visual humor through semiotic approaches in the near future. Then it can be essencial research for the appropriate situational uses of humor related to media, product, and audience factors, such as nationality, age, standard of living, sexuality, and so on.

A recent sharp increase of the biomedical literature causes researchers to struggle to grasp the current research trends and conduct creative studies based on the previous results. In order to alleviate their difficulties in keeping up with the latest scholarly trends, numerous attempts have been made to develop specialized analytic services that can provide direct, intuitive and formalized scholarly information by using various text mining technologies such as information extraction and event detection. This paper introduces and evaluates total 8 Convolutional Neural Network (CNN) models for extracting biomedical events from academic abstracts by applying various feature utilization approaches. Also, this paper conducts performance comparison evaluation for the proposed models. As a result of the comparison, we confirmed that the Entity-Type-Fully-Connected model, one of the introduced models in the paper, showed the most promising performance (72.09% in F-score) in the event classification task while it achieved a relatively low but comparable result (21.81%) in the entire event extraction process due to the imbalance problem of the training collections and event identify model's low performance.

As a preliminary study to evaluate the reliability of the calculation method of fire load for residential furniture combustibles, the present study estimates the fire load considering the volume data obtained by the 3D geometrical information of combustibles and material properties based on the literature survey and sample burning test. A kitchen sink cabinet, couch and workstation were investigated for estimating its fire load and real fire test have been performed to measure total energy released from the combustibles. Based on total energy measured from real fire test, the relative error of the estimated fire load due to literature survey and measured material properties showed 6~120% and less than 20%, respectively. It shows that the estimation error of fire load are greatly affected by its material properties as well as geometrical information of combustibles and the present study will be able to contribute to accurate estimation of fire load.

This paper employs entitymetrics analysis on the research works of Dong-ju Yun. He was a Korean poet who was studied by many researchers on his works, religion and life. We collected 1,076 papers about Dong-ju Yun and conducted various approaches including co-author citation analysis, topic modeling analysis to identify the topic trend in the study of Dong-ju Yun. Also we extracted entities like person's name and literature's title from abstract to examine the relationship among them. The result of this paper enables us to objectively identify the topic trend and infer implicit relationships between key concept associated with Dong-ju Yun based on text data. Moreover, we observed sub-research topics such as life, poem, aesthetic existence, comparative literature, literary translation, and religious beliefs. This paper shows how entitymetrics can be utilized to study intellectual structures in the humanities.

Flowery Knotweed Root is the dried tuberous root of the knotweed family wheres Auriculate Swallowwort Root is the dried tuberous root of the swallowort family. Flowery Knotweed Root is also called Red Flowery Knotweed Root in China, which is dried root of Polygonum multiflorum THUMB. Chinese Flowery Knotweed Root is better known as the dried tuberous root belonging to the family Apocynaceae whereas White Flowery Knotweed Root in Korea is the dried tuberous root of Cynanchum wilfordii(Maxim) Hemsl. Up to now, while the dried root named Red Flowery Knotweed Root has been widely used in China, Auriculate Swallowwort Root has been widely used in Korea. Both the roots contrast in a striking way with the origin, shape, botanical names, other names, and chemical constituents, so administration and dosage without discrimination of both sides can be open to question. According to the literature, it is recorded that Flowery Knotweed Root and Auriculate Swallowwort Root are similar to the characteristics, properties, and actions. From this study, the result is as follows: 1. Flowery Knotweed Root and Auriculate Swallowwort Root are divided into the family Apocynaceae and the family Polygonaceae, respectively. Accordingly 2. Flowery Knotweed Root is in shape of an irregular spindle and looks reddish- brown or deep reddish-brown and the section is light yellowish-brown, while Auriculate Swallowwort Root looks yellowish-brown and the section is white or yellow. 3. Flowery Knotweed Root is reported by the Journal of the Crude Drug that the medicinals have not the same therapeutic action as Auriculate Swallowwort Root. It is recorded that the properties, channel entry, functions of Flowery Knotweed Root and Auriculate Swallowwort Root in literature have much in common. Many works on the roots of this plant has been used traditionally as a tonic are required of. In view of the results, Flowery Knotweed Root and Auriculate Swallowwort Root varies both in nature and in shape, so that the administration and dosage of the medicinals must be taken a prudent attitude.

Current assumptions are used in the formulation of pseudo-first (PFO) and second-order (PSO) models to describe the kinetic data of filtration based on ideal operating conditions. This paper presents a new model developed with pseudo n^th order and based on real assumption. A comparison was performed between PFO, PSO and the new model to highlight their performance and the optimisation of the pseudo-order equation, using MATLAB software. Adsorption characteristic of bovine serum albumin adsorption on the track-etched membrane are used as a medium based on protein filtration data were extracted from the literature for different concentrations to demonstrate the comparison between PFO/PSO and the new model. The pseudo first and second-order kinetic models were applied to test the experimental data and they did not provide reasonable values. The results show that the predicted values are consistent with experimental values giving a good correlation coefficient R² = 0.997 and a minimum root mean squared error RMSE = 0.0171. Indeed, the experimental results follow the new model and the optimal pseudo equation order n = 1.115, the most suitable curves for the new model. As a result, we used different experimental adsorption data from the literature to examine and check the applicability and validity of the model.
