Abstract

Purpose

This paper aims to improve operational efficiency and minimize accident frequency in cold storage facilities through adopting an effective occupational safety and health program. The hidden knowledge can be extracted from the warehousing operations to create the comfortable and safe workplace environment.

Design/methodology/approach

A fuzzy association rule-based knowledge management system is developed by integrating fuzzy association rule mining (FARM) and rule-based expert system (RES). FARM is used to extract hidden knowledge from real operations to establish the relationship between safety measurement, personal constitution and key performance index measurement. The extracted knowledge is then stored and adopted in the RES to establish an effective occupational and safety program. Afterwards, a case study is conducted to validate the performance of the proposed system.

Findings

The results indicate that the aforementioned relationship can be built in the form of IF-THEN rules. An appropriate safety and health program can be developed and applied to all workers, so that they can follow instructions to prevent cold induced injuries and also improve the productivity.

Practical implications

Because of the increasing public consciousness of occupational safety and health, it is important for the workers in cold storage facilities where the ambient temperature is at/below 10°C. The proposed system can address the social problem and promote the importance of occupational safety and health in the society.

Originality/value

This study contributes to the knowledge management system for improving the occupational safety and operational efficiency in the cold storage facilities.

Abstract

Purpose

Since the handling of environmentally sensitive products requires close monitoring under prescribed conditions throughout the supply chain, it is essential to manage specific supply chain risks, i.e. maintaining good environmental conditions, and ensuring occupational safety in the cold environment. The purpose of this paper is to propose an Internet of Things (IoT)-based risk monitoring system (IoTRMS) for controlling product quality and occupational safety risks in cold chains. Real-time product monitoring and risk assessment in personal occupational safety can be then effectively established throughout the entire cold chain.

Design/methodology/approach

In the design of IoTRMS, there are three major components for risk monitoring in cold chains, namely: wireless sensor network; cloud database services; and fuzzy logic approach. The wireless sensor network is deployed to collect ambient environmental conditions automatically, and the collected information is then managed and applied to a product quality degradation model in the cloud database. The fuzzy logic approach is applied in evaluating the cold-associated occupational safety risk of the different cold chain parties considering specific personal health status. To examine the performance of the proposed system, a cold chain service provider is selected for conducting a comparative analysis before and after applying the IoTRMS.

Findings

The real-time environmental monitoring ensures that the products handled within the desired conditions, namely temperature, humidity and lighting intensity so that any violation of the handling requirements is visible among all cold chain parties. In addition, for cold warehouses and rooms in different cold chain facilities, the personal occupational safety risk assessment is established by considering the surrounding environment and the operators’ personal health status. The frequency of occupational safety risks occurring, including cold-related accidents and injuries, can be greatly reduced. In addition, worker satisfaction and operational efficiency are improved. Therefore, it provides a solid foundation for assessing and identifying product quality and occupational safety risks in cold chain activities.

Originality/value

The cold chain is developed for managing environmentally sensitive products in the right conditions. Most studies found that the risks in cold chain are related to the fluctuation of environmental conditions, resulting in poor product quality and negative influences on consumer health. In addition, there is a lack of occupational safety risk consideration for those who work in cold environments. Therefore, this paper proposes IoTRMS to contribute the area of risk monitoring by means of the IoT application and artificial intelligence techniques. The risk assessment and identification can be effectively established, resulting in secure product quality and appropriate occupational safety management.

Abstract

Purpose

In view of the elderly caregiving service being in high demand nowadays, the purpose of this paper is to develop an intelligent e-healthcare system for the domestic care industry by using the Internet of Things (IoTs) and Fuzzy Association Rule Mining (FARM) approach.

Design/methodology/approach

The IoTs connected with the e-healthcare system collect real-time vital sign monitoring data for the e-healthcare system. The FARM approach helps to identify the hidden relationships between the data records in the e-healthcare system to support the elderly care management tasks.

Findings

To evaluate the proposed system and approach, a case study was carried out to identify the association between the specific collected demographic data, behavior data and the health measurements data in the e-healthcare system. It is found that the discovered rules are useful for the care management tasks in the elderly healthcare service.

Originality/value

Knowledge discovery in databases uses various data mining techniques and rule-based artificial intelligence algorithms. This paper demonstrates complete processes on how an e-healthcare system connected with IoTs can support the elderly care services via a data collection phase, data analysis phase and data reporting phase by using the FARM to evaluate the fuzzy sets of the data attributes. The caregivers can use the discovered rules for proactive decision support of healthcare services and to improve the overall service quality by enhancing the elderly healthcare service responsiveness.

Abstract

Purpose

The purpose of this paper is to show how a clinical decision support system can help in prescription and knowledge acquisition processes.

Design/methodology/approach

An integrated electronic medical records system (iEMRS) is designed to enhance the decision support quality in prescription.

Findings

By evaluating the system performance through 135 prescription records collected from a Hong Kong medical organization, iEMRS shows a satisfactory result in suggesting medicines that is properly the same as the decisions made by the physicians.

Originality/value

Compared with the static clinical guidelines built (manually) in the traditional clinical decision support system, knowledge in iEMRS is generated by the knowledge discovery result from professional experiences of various physicians and patient histories, which are more dynamic in nature. A treatment algorithm, designed in data mining technique, is introduced to improve information management in medical organizations by integration of decision support capability and EMRS, and supplement the deficiencies of traditional clinical decision support system.

Abstract

A pæan of joy and triumph which speaks for itself, and which is a very true indication of how the question of poisonous adulteration is viewed by certain sections of “the trade,” and by certain of the smaller and irresponsible trade organs, has appeared in print. It would seem that the thanks of “the trade” are due to the defendants in the case heard at the Liverpool Police Court for having obtained an official acknowledgment that the use of salicylic acid and of other preservatives, even in large amounts, in wines and suchlike articles, is not only allowable, but is really necessary for the proper keeping of the product. It must have been a charming change in the general proceedings at the Liverpool Court to listen to a “preservatives” case conducted before a magistrate who evidently realises that manufacturers, in these days, in order to make a “decent” profit, have to use the cheapest materials they can buy, and cannot afford to pick and choose; and that they have therefore “been compelled” to put preservatives into their articles so as to prevent their going bad. He was evidently not to be misled by the usual statement that such substances should not be used because they are injurious to health— as though that could be thought to have anything to do with the much more important fact that the public “really want” to have an article supplied to them which is cheap, and yet keeps well. Besides, many doctors and professors were brought forward to prove that they had never known a case of fatal poisoning due to the use of salicylic acid as a preservative. Unfortunately, it is only the big firms that can manage to bring forward such admirable and learned witnesses, and the smaller firms have to suffer persecution by faddists and others who attempt to obtain the public notice by pretending to be solicitous about the public health. Altogether the prosecution did not have a pleasant time, for the magistrate showed his appreciation of the evidence of one of the witnesses by humorously rallying him about his experiments with kittens, as though any‐one could presume to judge from experiments on brute beasts what would be the effect on human beings—the “lords of creation.” Everyone reading the evidence will be struck by the fact that the defendant stated that he had once tried to brew without preservatives, but with the only result that the entire lot “went bad.” All manufacturers of his own type will sympathise with him, since, of course, there is no practicable way of getting over this trouble except by the use of preservatives; although the above‐mentioned faddists are so unkind as to state that if everything is clean the article will keep. But this must surely be sheer theory, for it cannot be supposed that there can be any manufacturer of this class of article who would be foolish enough to think he could run his business at a profit, and yet go to all the expense of having the returned empties washed out before refilling, and of paying the heavy price asked for the best crude materials, when he has to compete with rival firms, who can use practically anything, and yet turn out an article equal in every way from a selling point of view, and one that will keep sufficiently, by the simple (and cheap) expedient of throwing theory on one side, and by pinning their faith to a preservative which has now received the approval of a magistrate. Manufacturers who use preservatives, whether they are makers of wines or are dairymen, and all similar tradesmen, should join together to protect their interests, for, as they must all admit, “the welfare of the trade” is the chief thing they have to consider, and any other interest must come second, if it is to come in at all. Now is the time for action, for the Commission appointed to inquire into the use of preservatives in foods has not yet given its decision, and there is still time for a properly‐conducted campaign, backed up by those “influential members of the trade” of whom we hear so much, and aided by such far‐reaching and brilliant magisterial decisions, to force these opinions prominently forward, in spite of the prejudice of the public; and to insure to the trades interested the unfettered use of preservatives,—which save “the trade” hundreds of thousands of pounds every year, by enabling the manufacturers to dispense with heavily‐priced apparatus, with extra workmen and with the use of expensive materials,—and which are urgently asked for by the public,—since we all prefer to have our foods drugged than to have them pure.

Abstract

The decision of the Wolverhampton Stipendiary in the case of “Skim‐milk Cheese” is, at any rate, clearly put. It is a trial case, and, like most trial cases, the reasons for the judgment have to be based upon first principles of common‐sense, occasionally aided, but more often complicated, by already existing laws, which apply more or less to the case under discussion. The weak point in this particular case is the law which has just come into force, in which cheese is defined as the substance “usually known as cheese” by the public and any others interested in cheese. This reliance upon the popular fancy reads almost like our Government's war policy and “the man in the street,” and is a shining example of a trustful belief in the average common‐sense. Unfortunately, the general public have no direct voice in a police court, and so the “usually known as cheese” phrase is translated according to the fancy and taste of the officials and defending solicitors who may happen to be concerned with any particular case. Not having the general public to consult, the officials in this case had a war of dictionaries which would have gladdened the heart of Dr. JOHNSON; and the outcome of much travail was the following definition: cheese is “ coagulated milk or curd pressed into a solid mass.” So far so good, but immediately a second definition question cropped up—namely, What is “milk?”—and it is at this point that the mistake occurred. There is no legal definition of new milk, but it has been decided, and is accepted without dispute, that the single word “milk” means an article of well‐recognised general properties, and which has a lower limit of composition below which it ceases to be correctly described by the one word “milk,” and has to be called “skim‐milk,” “separated milk,” “ milk and water,” or other distinguishing names. The lower limits of fat and solids‐not‐fat are recognised universally by reputable public analysts, but there has been no upper limit of fat fixed. Therefore, by the very definition quoted by the stipendiary, an article made from “skim‐milk” is not cheese, for “skim‐milk” is not “milk.” The argument that Stilton cheese is not cheese because there is too much fat would not hold, for there is no legal upper limit for fat; but if it did hold, it does not matter, for it can be, and is, sold as “Stilton” cheese, without any hardship to anyone. The last suggestion made by the stipendiary would, if carried out, afford some protection to the general public against their being cheated when they buy cheese. This suggestion is that the Board of Agriculture, who by the Act of 1899 have the legal power, should determine a lower limit of fat which can be present in cheese made from milk; but, as we have repeatedly pointed out, it is by the adoption of the Control system that such questions can alone be settled to the advantage of the producer of genuine articles and to that of the public.

Abstract

The Departmental Committee appointed to inquire into the use of preservatives and colouring matters in the preservation and colouring of food, have now issued their report, and the large amount of evidence which is recorded therein will be found to be of the greatest interest to those concerned in striving to obtain a pure and unsophisticated food‐supply. It is of course much to be regretted that the Committee could not see their way to recommend the prohibition of all chemical preservatives in articles of food and drink; but, apart from this want of strength, they have made certain recommendations which, if they become law, will greatly improve the character of certain classes of food. It is satisfactory to note that formaldehyde and its preparations may be absolutely prohibited in foods and drinks; but, on the other hand, it is suggested that salicylic acid may be allowed in certain proportions in food, although in all cases its presence is to be declared. The entire prohibition of preservatives in milk would be a step in the right direction, although it is difficult to see why, in view of this recommendation, boric acid should be allowed to the extent of 0·25 per cent. in cream, more especially as by another recommendation all dietetic preparations intended for the use of invalids or infants are to be entirely free from preservative chemicals; but it will be a severe shock to tho3e traders who are in the habit of using these substances to be informed that they must declare the fact of the admixture by a label attached to the containing vessel. The use of boric acid and borax only is to be permitted in butter and margarine, in proportions not exceeding 0·5 per cent. expressed as boric acid, without notification. It is suggested that the use of salts of copper in the so‐called greening of vegetables should not be allowed, but upon this recommendation the members of the Committee were not unanimous, as in a note attached to the report one member states that he does not agree with the entire exclusion of added copper to food, for the strange reason that certain foods may naturally contain traces of copper. With equal truth it can be said that certain foods may naturally contain traces of arsenic. Is the addition of arsenic therefore to be permitted? The Committee are to be congratulated upon the result of their labours, and when these recommendations become law Great Britain may be regarded as having come a little more into line— although with some apparent reluctance—with those countries who regard the purity of their food‐supplies as a matter of national importance.

Abstract

In a recent speech LORD ROSEBERY charged the people of this country with possessing, to an inordinate extent, the fatal gift of complacency, and he observed that the nation which is not progressive is retrogressive. “Rest and be thankful,” said LORD ROSEBERY, is a motto which spells decay, and those who have any experience of the methods of the manufacturers of the country will admit that this seemingly severe impeachment is by no means unfounded or uncalled‐for. Industries, of which at one time the English were masters, are now gradually falling into other hands. The workers of other lands are successfully competing with our own, and yet, in spite of this condition of our mercantile affairs, the spirit of complacency is rampant. The sons are content to continue in the footsteps of the fathers, oblivious of the fact that time and seasons do not stand still and that they may be overwhelmed by the advancing flood of competition. The trade conservatism which was in the past opposed to the introduction of the steam‐engine, the power‐loom, and other mechanical appliances, is still responsible for the extreme slowness with which English firms appreciate the necessity for such innovations in the conduct of their business as would place them in a position to hold their own in the markets of the world. In respect to the protection of pure food production Great Britain and the British manufacturers are still a long way behind. Although the Sale of Food and Drugs Act of 1875 was one of the first Acts passed in any country to prevent the sale of adulterated food and drink, its machinery is cumbrous, and the subsequent Amendment Acts have not added materially to its efficiency; with the result that the Adulteration Acts do not compare favourably with those of many other countries. The spirit of complacency in regard to food products has affected alike the producer and the distributor, and the result is that in many instances there is no adequate inducement to produce anything but a mediocre article—such an article, in fact, as only escapes condemnation because of the faulty construction of the machinery of the law.

Abstract

Numbers of worthy people are no doubt nursing themselves in the fond and foolish belief that when the Food Bill has received the Royal assent, and becomes law, the manufacture and sale of adulterated and sophisticated products will, to all intents and purposes, be suppressed, and that the Public Analyst and the Inspector will be able to report the existence of almost universal purity and virtue. This optimistic feeling will not be shared by the traders and manufacturers who have suffered from the effects of unfair and dishonest competition, nor by those whose knowledge and experience of the existing law enables them to gauge the probable value of the new one with some approach to accuracy. The measure has satisfied nobody, and can satisfy nobody but those whose nefarious practices it is intended to check, and who can fully appreciate the value, to them, of patchwork and superficial legislation. We have repeatedly pointed out that repressive legislation, however stringent and however well applied, can never give the public that which the public, in theory, should receive—namely, complete protection and adequate guarantee,—nor to the honest trader the full support and encouragement to which he is entitled. But, in spite of the defects and ineffectualities necessarily attaching to legislation of this nature, a strong Government could without much difficulty have produced a far more effective, and therefore more valuable law than that which, after so long an incubation, is to be added to the statute‐book.
