In Taiwan, the export-oriented economy of traditional aquaculture is faced with the harshest conditions, such as environmental pollution, diseases and drug overdose. In addition, the traditional aquaculture fields are usually open-air for costing a lot on employing labors. Consequently, it is necessary to set up an intelligent aquaculture system for solving the above problems effectively. This study which was based on these technologies of internet of things (IoT), cloud computing and Long Range Low Power Wide Area Network (LoRa LPWAN), was designed a daily management system for auto-controlling on production planning, energy conservation and reducing labor costs. The users can operate this system which can both monitor the water quality and control these real-time aquaculture parameters (temperature, pH, illuminance and electrical conductivity) by simply using the remote user interface. This system is a modular design that is user-friendly and portable. After all, we expect that it will be great helpful to construct an automatic control platform for improving aquaculture efficiency in future.

Will My Customers Come Back? A Study of Beauty Salons in Taiwan

Yun-Yung Lin,Tzong-Ru (Jiun-Shen) Lee,Hooi Hooi Lean,Hsiang-Ying Lan 한국유통과학회 2018 유통과학연구 Vol.16 No.1

Purpose – The beauty salon industry is a highly competitive market. Every beauty salon shop aims to keep its customers satisfied and hopes that they will revisit several times. Hence, this paper investigates the key factors affecting the repurchase intention of consumers in the beauty salon industry in Taiwan. Research design, data, and methodology – We first use the content analysis of free-response narratives from beauticians to classify the key factors objectively and develop the questionnaire accordingly. We then distribute the questionnaire to 130 beauty salon consumers to complete the questionnaire. Next, the Grey Relation Analysis is employed to identify the key factors that affect the repurchase intention of consumers in the beauty salon industry. Results – From the perspectives of the beauty salon customers, the factors affecting the repurchase intention of consumers are (1) obvious treatment results, (2) the treatment space considers personal privacy, (3) the offer of promotional prices for treatment/product trials, and (4) the product knowledge of the beauticians. From the perspectives of the beauticians, the factors include (1) the treatment space is well-designed and makes the customers feel relaxed, (2) enhancement of the customer relationship, (3) the treatment space considers personal privacy, and (4) the positive service attitude of the beauticians. Conclusions – We analyze all the key factors and offer some suggestions as a conclusion.

How Are Migrants Viewed in the Eyes of Employers? Double Exclusion among Immigrants in Taiwan

김혜나,Yun Hsiang Hsu,Chih-Yu Chen,Kuo-Jung Lin 숙명여자대학교 아시아여성연구원 2020 OMNES: The Journal of Multicultural Society Vol.10 No.2

While many countries are open to those born elsewhere being part of their nation, surveys find that this acceptance comes with a certain prerequisite—that it is important to speak the dominant language. This prerequisite has been continuously observed and studied in the field of labor market performance. This study surveys 1,043 employers in Taiwan for their willingness to hire foreign brides from Southeast Asia or Mainland China. The link between the proficiency of the use of language among immigrants and direct job discrimination in Taiwanese workplaces is confirmed. Results show that vocational trainings provided by the government to immigrants are not positively associated with a willingness to hire among employers. Policy recommendations are provided with regard to the establishment of language courses.

Controlled Release of Clenbuterol from a Hydroxyapatite Carrier for the Treatment of Alzheimer’s Disease

Background Alzheimer’s disease is a neurodegenerative disorder, and Aβ aggregation is considered to be the central process implicated in its pathogenesis. Current treatments are faced by challenges such as serious side effects and reduced drug bioavailability. In this study, we developed a drug delivery system for intramuscular injection that uses cellular activity to achieve constant and long-term drug release. Methods Synthesized mesoporous hydroxyapatite (SHAP) was prepared via co-precipitation, and hydrophobic surface modification using stearic acid was then used to load clenbuterol by physical absorption, thus creating the drug delivery system. Clenbuterol release was achieved through cellular activity, with macrophage uptake triggering lysosome/endosome disruption, cytoplasmic release, extracellular exocytosis, and subsequent systemic circulation. Results We found that clenbuterol-loaded SHAP enabled sustained release for more than 2 weeks and effectively modulated inflammation, reduced Aβ oligomer-induced toxicity, and prevented Aβ aggregation. Conclusions Our findings suggest that treatment with clenbuterol loaded in this SHAP delivery system could be a promising strategy for treating Alzheimer’s disease.

A Cosmopolitan Approach to Transboundary Risk Governance in East Asia

Kuei Tien Chou,Yun Hsiang Lin,Jui Ning Chang 서울대학교 사회발전연구소 2022 Journal of Asian Sociology Vol.51 No.3

This paper points out that while genetically modified organisms (GMOs), bovine spongiform encephalopathy (BSE), and the Fukushima nuclear disaster that respectively occurred in the three East Asian countries of Taiwan, South Korea, and Japan, resulted in the emergence of compulsory cosmopolitanism, from the perspective of cross-border and transnational action. Although these countries all have full social movements domestically, a failure to develop connections between their organizations has resulted in these countries not yet seeing the emergence of cosmopolitan risk collectivities and a regional risk community. The authors explain that these countries have a common historical background of authoritarian politics, with all three possessing the structural factors of expert politics, scientific hegemony, and economic developmentalism. Such conditions formulate the hidden ignorance of risk and stagnates transformation. Therefore, not only are we yet to see any transnational connections between the NGOs in East Asia but there is also an emerging “hung risk governance.”

Three methods for studying coupled vibration in a multi flexible disk rotor system

YiJui Chiu,Xiao-Yun Li,Yi-Cheng Chen,Sheng-Rui Jian,Chia-Hao Yang,I-Hsiang Lin 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.11

This paper improved and developed Shaft-disk-blade (SDB) rotor system based on the previous studies of the authors in the last decade from Yang and Huang (2005) to Chiu et al. (2017). This paper also explored blade-bending, disk-transverse, and shaft-torsion coupling vibration of a multi flexible disk rotor system. Unlike the previous studies of the authors, this paper adopted three methods: (a) Assumed mode method (AMM), (b) Finite element method (FEM), and (c) experimental method. The first approach is the main method, and the two other methods are complementary. Results generated from the three methods were then compared and analyzed. Based on the previous definition of the authors, a flexible disk rotor system displays three types of coupling vibrations: Inter-blade, SDB, and diskblade modes. The system changes the rules of natural frequencies and mode shapes. This paper presents several interesting results. First, the author determined the change rules of the mode shapes and natural frequencies using the AMM, FEM (including three kinds of software), and the experimental method. Second, numerical calculation results also revealed that two phenomena regarding the distance of disk and flexible disk would be affected by the natural frequencies. Third, the experimental results would be explored in this paper. Last, the flexible disk could affect the system instability in the case study of rotation effects.
