This research aimed to survey foodservice hygiene management practices performed by principals and teachers as well as examine foodservice employees' hygiene knowledge in kindergartens. Surveys were administered to principals, teachers, and foodservice employees at 392 kindergartens. The total average score of six categories was 4.28 out of 5.0. Average score of the production process management category was the lowest at 3.90 while safety management was the highest at 4.69. Other average scores were as follows: facilities and equipment 4.20, personal hygiene 4.14, food ingredient control 4.35, and environmental sanitation 4.39. Teachers' foodservice hygiene management practices scored 3.8 points out of 5 on average. Hygiene knowledge of foodservice employees was also tested. The mean score of foodservice hygiene knowledge was 76.29%. The lowest scoring category was personal hygiene, suggesting that foodservice employees require more knowledge on proper personal hygiene practices. Possession rates of dish sterilizer, ultraviolet sterilizer, and hand washing facilities in the kitchen were low. These equipment installation rates should be raised accordingly. To enhance control of foodservice hygiene, kindergarten management should pay more attention to education and training related to foodservice sanitation.

The present study primarily focuses on the evaluation of the comparative effect of chemical coagulation and ultrasonication for elimination of aromatic amines (AAs) present in anaerobically pretreated textile wastewater containing different types of dyes including azo dyes. Color and COD reduction was also monitored at the optimized conditions. The production of AAs was measured spectrophotometrically in the form of total aromatic amines (TAAs) and also verified with high performance liquid chromatography (HPLC) selectively. A composite coagulant, magnesium chloride (MC) aided with aluminium chlorohydrate (ACH) in an equal ratio (MC + ACH) was utilized during the coagulation process, which yielded 31% of TAAs removal along with 85% of color and 52% of COD reduction. At optimized power (200 W) and sonication time (5 h), an appreciable TAAs degradation efficiency (85%) was observed along with 51% color reduction and 62% COD removal using ultrasonication. The chromatographic data indicate that sulphanilic acid and benzidine types of aromatic amines were produced after the reductive cleavage of utilized textile dyes, which were effectively mineralized after ultrasonication. The degradation followed the first order kinetics with a correlation coefficient ($R^2$) of 0.89 and a first-order kinetic constant (k) of $0.0073min^{-1}$.

Modern production systems are very complex by request of automation, and failure modes that occur in thisautomatic system are very various and complex. The efficient fault diagnosis for these complex systems is essential for productivity loss prevention and cost saving. Traditional fault diagnostic system which perforns sequential fault diagnosis can cause catastrophic failure during diagnosis when fault propagation is very fast. This paper describes the Real-time Intelligent Multiple Fault Diagnosis System (RIMFDS). RIMFDS assesses current machine condition by using sensor signals. This system deals with multiple fault diagnosis, comprising of two main parts. One is a personal computer for remote signal generation and transmission and the other is a host system for multiple fault diagnosis. The signal generator generates various faulty signals and image information and sends them to the host. The host has various modules and agents for efficient multiple fault diagnosis. A SUN workstation is used as a host for multiple fault modules and agents for efficient multiple fault diagnosis. A SUN workstation is used as a host for multiple fault diagnosis and graphic representation of the results. RIMFDS diagnoses multiple faults with fast fault propagation and complex physical phenomenon. The new system based on multiprocessing diagnoses by using Hierarchical Artificial Neural Network (HANN).

현재 설계교육에서 디지털 기술매체는 새로운 디자인 매체로 재인식되어 설계 커리큘럼에도 적지 않은 영향을 주고 있다. 산업적으로도 비정형 설계가 증가하면서 디지털 디자인의 가능성을 실험하는 진보적 건축 그룹들이 등장해서 실질적인 디지털 설계교육으로 전환을 촉구하고 있다. 국내 설계교육에서도 디지털 관련 과목이 다양하게 개설되어 운영되고 있지만, 기존 설계스튜디오를 보조하는 교과과정으로 운영되는 형편이다. 따라서 국내의 설계교육에서도 실무분야의 디지털 설계 전문가를 양성할 수 있는 교육모델이 제시되고 운영되어야 하며, 더불어 건축설계에서 디지털 패러다임의 적용 가능성을 탐구할 필요가 있다. 이런 배경에서 본 연구는 디지털 설계의 이론적 고찰과 교육 사례 고찰을 통해 건축설계 교육에 적용 가능한 디지털 설계 커리큘럼 모델을 제안하고자 한다.

One of the core pillars of the Fourth Industrial Revolution is the innovation of the manufacturing industry. From the beginning, the 4th Industrial Revolution appeared in Germany under the concept of 'Industrial 4.0', which means a radical change in the manufacturing industry that can provide super intelligent product production and services based on artificial intelligence and big data. Since manufacturing innovation is a change in the industrial character of the entire nation, the initial role of government is important. Korea also has various policies related to the 4th Industrial Revolution, but there are still various problems to be solved. Therefore, this paper monitors and analyzes the public R&D projects of the advanced countries on manufacturing innovations in the background mentioned above, and through this, the policy implications are drawn.

Background: The high sensitivity of individuals toward safety information in production activities, that is, attentional bias toward safety (ABS), can positively predict safe behaviors. It has become a hot topic in current organizational safety behavior research. However, there is no literature on its modification method. Methods: Based on the modified dot-probe task, we designed a modification training method of ABS. The training method required subjects to respond to the location of detection points that presented after safety stimulus and neutral stimulus pictures. Subjects' attentional bias values of safety and neutral pictures were measured during the experiment. Twenty-one students were selected and divided into a control group and training group to gain comparable results. Results: A novel training method was developed in this study to promote the efficacy of safety stimulus by activating ABS of the subjects. Moreover, repeated trainings and preacquired relative knowledge can enhance this effect. Conclusion: This study develops an experimental approach to evaluate the effectiveness of safety education and safety training, and also provides a new research idea for accident prevention.

The mass production after the industrialisation and the fast changing fashion cycles in today's world resulted in buying clothes and home textiles more than we need and discarding them before they complete their life cycles. This causes vast amounts of textile waste that creates environmental issues. Upcycling is the creative process of transforming clothing and textile waste by reusing deadstock or used fabric to create new garments and products. It holds importance in terms of sustainability, reducing waste and environmental pollution. During the process of upcycling, certainly the creativity and innovation are the key words because to reuse a product to a better value needs a creative mind, aesthetic consciousness, innovative look and knowledge and it is quite different from a normal design procedure. There is a delicate level of aesthetics which carries the reused materials to a higher value. The handling of the materials, knowing how to manipulate the waste material, the techniques available to apply to surfaces, the concept of two and three dimension on textiles and clothing, contributions of other branches of art such as sculpture and painting all help the designer to reach a higher aesthetic value in the upcycled product in this process. In the study; it was aimed to raise awareness, to attract attention to sustainable fashion and also to contribute to sustainable development as an upcycling design project realized with students in textile and fashion design education taken as an example.
