The important thing in the field of deep learning is to find out the appropriate hyper-parameter for image classification. In this study, the main objective is to investigate the performance of various hyper-parameters in a convolutional neural network model based on the image classification problem. The dataset was obtained from the Kaggle dataset. The experiment was conducted through different hyper-parameters. For this proposal, Stochastic Gradient Descent without momentum (SGD), Adaptive Moment Estimation (Adam), Adagrad, Adamax optimizer, and the number of batch sizes (16, 32, 64, 120), and the number of epochs (50, 100, 150) were considered as hyper-parameters to determine the losses and accuracy of a model. In addition, Binary Cross-entropy Loss Function (BCLF) was used for evaluating the performance of a model. In this study, the VGG16 convolutional neural network was used for image classification. Empirical results demonstrated that a model had minimum losses obtain by Adagrad optimizer in the case of 16 batch sizes and 50 epochs. In addition, the SGD with a 32 batch sizes and 150 epochs and the Adam with a 64 batch sizes and 50 epochs had the best performance based on the loss value during the training process. Interestingly, the accuracy was higher while performing the Adagrad and Adamax optimizer with a 120 batch sizes and 150 epochs. In this study, the Adagrad optimizer with a 120 batch sizes and 150 epochs performed slightly better among those optimizers. In addition, an increasing number of epochs can improve the performance of accuracy. It can help to create a broader scope for further experiments on several datasets to perceive the suitable hyper-parameters for the convolutional neural network.

본 논문은 산문 “Magic,” “Swedenborg, Mediums, and the Desolate Places,” Per Amica Silentia Lunae와 A Vision에 나타난 예이츠의 영성에 대한 생각을 살펴보는데 그 목적이 있다. 우선 본격적인 논의에 앞서, 이 논문은 예이츠가 유년 시절에 접했던 민담과 아버지의 기성 종교에 대한 비판과 같은 예이츠 특유의 영성을 형성한 여러 가지 요소들에 대하여 살펴본다. 이러한 유년 시절의 영향은 예이츠로 하여금 기성 종교와 대비되는 대안적인 형태의 영성을 추구하게 만들었으며 이는 신지 학회와 황금여명회 가입으로 이어진다. 이는 또한 예이츠가 아일랜드의 민담과 전설 등 아일랜드의 고유한 전통에 바탕을 둔 특유의 영성 이론을 발전시키는데 도움을 준다. 다음으로, 논문은 예이츠의 1901년 에세이 “Magic”부터 영성에 대한 추구가 집대성 되어 있다고 볼 수 있는 A Vision에 이르기까지의 예이츠의 산문을 살펴봄으로써 예이츠가 어떠한 방식으로 영성에 대한 생각을 글로써 표현하고자 하였는지에 대하여 논의하고자 한다.

In 2019, two court rulings in China on the issue of copyrightability of AI creations received international attention. It was reported that in Feilin v. Baidu, known as the first AI case, the Beijing Internet Court denied copyright of AI creations, whereas the Shenzhen Nanshan District People’s Court acknowledged copyright of AI creations in the Tencent Dreamwriter case. The two cases, however, were quite similar, as they acknowledged copyright of AIassisted, not AI-generated, written works and recognized these works as a work of a legal entity. The difference between the two judgments is that the Beijing Internet Court regarded originality as an independent requirement and judged it according to the objective standard, whereas the Shenzhen Nanshan District People’s Court regarded human creation as part of the requirement of originality. In this sense, it was the Beijing Internet Court that actually made the more favorable judgment on an AI-generated work.

Hispidin is a secondary metabolite found in numerous medicinal mushrooms that has attracted significant attention, owing to its distinct biological effects, including antioxidant, anti-inflammatory, antitumor, and cytoprotective properties. Experiments are being carried out to study the interaction of detonation nanodiamonds (DNDs) with synthetic and natural hispidin sourced from extracts of Pholiota sp. fungus. The bioluminescence method is used to determine the adsorption/ desorption properties of DNDs toward hispidin. It is found that hispidin forms strong conjugates with DNDs, and the use of various eluents does not result in a significant release of the adsorbed hispidin molecules. DND-bovine serum albumin (BSA) complex, where DNDs serve as a carrier for the protein and the latter acts as a hispidin sorbent, has been developed and applied in hispidin adsorption/desorption tests. The results support the use of the DNDs as a carrier for hispidin in medical applications. They also advocate the application of the DND-BSA complex for isolating the substance from fungal extracts.

The Indonesian Ocean Policy (IOP) is a new milestone in managing its oceans since Indonesia ratified the UNCLOS 35 years ago. Indonesia underwent several paradigm shifts in strengthening ocean governance from 1957 to 2014. This research aims to analyse three paradigm shifts in strengthening ocean governance in Indonesia. The research revealed that the milestone of the first shift was the 1957 Djuanda Declaration, recognised by the UNCLOS in 1982, regarding the concept of an archipelago state, called the ‘ocean space paradigm.’ The second, which occurred in the Reformation period (1998-2014) was called the Ocean Development paradigm, while the third paradigm shift was after President Jokowi launched Indonesia’s vision as a Global Maritime Fulcrum. This third paradigm shift was also associated with the emergence of the IOP, which contributes to national development and pays comprehensive attention to the constellation of relations between the countries in Asia and various initiatives in the region.

The social media influencer (SMI) phenomenon is attracting attention from academia and business. A SMI refers to an individual who has accumulated a sizable social network of followers and thereby has influence over others (Ki et al., 2020). Due to the influence SMIs possess, an increasing number of brands are approaching SMIs and asking them to create and share branded content that includes product placements or brand recommendations. This practice is commonly referred to as influencer marketing. Reflecting the trend of influencer marketing, this study investigated: (1) whether consumers are ‘inspired-by’ SMIs and ‘inspired-to’ adopt the exemplars of SMIs (e.g., SMIs’ lifestyles, styles, and recommendations) as their social defaults that provide desirable standards that consumers will like and follow, and if so, (2) what are its causal factors and effects, and (3) whether the inspiration mechanism between SMIs and consumers differs between male and female consumers. In so doing, we drew on social defaults theory (Huh et al., 2014) and customer inspiration theory (Böttger et al., 2017).

This study investigates the association between Food Neophobia and the intention of the consumers to buy fish farmed with insect-based flours. The findings suggest that buying intention is strongly influenced by the attitude of consumers toward this type of fish and both Food Neophobia and Food Technology Neophobia negatively influence consumers’ attitude.
