Fresh pork belly is a highly popular meat in South Korea, accounting for 59 % of the approximately 100 g of meat per capita that is consumed daily. Fresh pork belly offers not only high-quality protein from the lean cuts but also substantial micronutrients including fat-soluble vitamins and minerals. However, fresh pork belly generally consists of about 30 % fat, with saturated fatty acids representing half of this value. Excessive consumption of saturated fatty acids increases total cholesterol, low-density lipoprotein-cholesterol, and triglycerides while decreasing high-density lipoprotein-cholesterol, raising concerns about an increased risk of hyperlipidemia, followed by cardiovascular diseases. In this review, we discuss the consumption and production trends in South Korea, the general characteristics, and health issues related to fresh pork belly to delineate the features of pork production and consumer welfare.

Representative observations are useful to express explicitly the distributional variation of the data by a few selected observations corresponding to the quantiles in the univariate situation. Jones and Rice(1992) extended it to the multidimensional case by the principal component based method. This study introduces a modified version of Jones and Rice exploiting the self-consistency of principal components in expressing the chosen observation vectors. Compared to that of Jones and Rice, the suggested method tends to provide with less susceptible representative observations to the sampling variation of the data and the resulted vectors benefits from the self-consistency.

Protecting an infant from a risk of accident was an absolute responsibility and duty of parents in the past. As increase in the ratio of entering kindergartens, the demand of all day program also increases. In infancy, safety concerns are higher than other periods since infants are curious about objects and environments and that have stronger impulse of the spirit of inquiry. Since baby's functioning is poor, an ability of balance maintenance and an exercise function are not sufficiently developed. Further more, they lack a cognitive power about self-control or situation. According to Korea Consumer Agency, safety accidents in infant institution have increased in 115% as 294 cases compared with 137 cases in 2004. Major causes of infant deaths are street accidents, drowning, and deaths from a fall in order. Considering this situation, we need to prevent and deal with accidents. Therefore this thesis grasp the situation and analyze an actual condition of an safety education about teachers who work in such institutions and infants who are educated in institutions to prevent from accidents and make up pleasant environments. Then, it will suggest all efficient safety education plans for infants to them.

In recent years, O2O (Online to Offline) services get a lot of attention to improve the trust in online shopping and minimize the inconvenience and the cost burden in offline shopping as the number of consumers, who do not show concern about the purchase platform like online or offline, increases. Even though the services have been getting the spotlight as a strong business platform for next generation commerce, there have been only a few studies on the O2O services. The purpose of this research is to investigate the factors which affect the consumer's intention to use location-based O2O services. The study is based on VAM (Value-based Adoption Model) which is able to analyze those factors from the aspects of benefit and sacrifice. We used the partial least squares (PLS) method for empirical analysis, and the result shows that contextual offers, instant connectivity, webrooming and economic efficiency, which fall under the benefit, affect perceived value positively while annoyance and face consciousness, which fall under the sacrifice, do not affect perceived value significantly. In addition, contextual offers and instant connectivity affect trust positively. Location accuracy, which falls under the benefit of location-based O2O service, do not significantly affect perceived value and trust while security risk affects trust and use intention negatively. It appears that trust affects perceived value and use intention positively.

The process of correcting, upgrading, and improving software products after they have been handed over to the consumer is known as software maintenance. Offshore software maintenance outsourcing (OSMO) clients benefit from cost savings, time savings, and improved quality software through OSMO. In most circumstances, the OSMO vendor makes a lot of money but not in all the cases. Especially, when the OSMO project offer is not properly assessed. An efficient outsourcing contract might yield successful outcomes for outsourced projects. But before sending a detailed proposal to bid on the OSMO project the vendor must have to assess the client's project (business offer) requirements. The purpose of this study is to find out common trends within the assessment of a OSMO project. A case study approach along with semi-structured interviews from eight companies concluded ten common practices and several roles. Among these practices, four (code structure, requirements, communication barriers and required infrastructure) were consistent amongst the responses .The findings, limitations and future work are discussed.

Receiving medical services abroad is an event that involves a high level of risk and stress for most people. This study proposes and empirically examines perceived control as a factor that has a potential to reduce the stress associated with overseas medical experience and enhance satisfaction with it. Based on the research findings in environmental psychology, one's perceived control was divided into cognitive control, behavior control, and decision control. A research model and a set of hypotheses were constructed to investigate the effect of each control on satisfaction and word-of-mouth communications among consumers who had overseas medical service experiences. The data collection was conducted through an online survey of 220 Chinese consumers who had visited Korea as plastic medicine tourists. Satisfaction with their service experience was significantly affected by both behavioral control and decisional control, but not by cognitive control. Thus, Chinese medical tourists prefer to maintain the belief that they are in charge of major decisions associated with the medical procedure, and that the results of the medical procedure will have personally desirable consequences. In addition, satisfaction experienced by Chinese consumers with overseas medical services had a significant impact on their word-of-mouth activities. Based on the research results, a set of academic and practical implications were derived.

Cloud computing provides each consumer with a large-scale computing tool. Different Cyber Attacks can potentially target cloud computing systems, as most cloud computing systems offer services to many people who are not known to be trustworthy. Therefore, to protect that Virtual Machine from threats, a cloud computing system must incorporate some security monitoring framework. There is a tradeoff between the security level of the security system and the performance of the system in this scenario. If strong security is needed, then the service of stronger security using more rules or patterns is provided, since it needs much more computing resources. A new way of security system is introduced in this work in cloud environments to the VM on account of resources allocated to customers are ease. The main spike of Fog computing is part of the cloud server's work in the ongoing study tells the step-by-step cloud server to change the tremendous measurement of information because the endeavor apps are relocated to the cloud to keep the framework cost. The cloud server is devouring and changing a huge measure of information step by step to reduce complications. The Medical Data Health-Care (MDHC) records are stored in Cloud datacenters and Fog layer based on the guard intensity and the key is provoked for ingress the file. The monitoring center sustains the Activity Log, Risk Table, and Health Records. Cloud computing and Fog computing were combined in this paper to review data movement and safe information about MDHC.

Hazardous substances are formed during food manufacturing, processing, or cooking, and may pose a threat to food safety. Here, we present a dietary exposure assessment of Korean consumer's intake of hazardous materials through a Total Diet Study (TDS) which was conducted by the Ministry of Food and Drug Safety (MFDS). The levels of exposure to materials such as acrylamide, furan, biogenic amines, etc., were estimated and risk assessments were then performed. Acrylamide and furan were selected as hazards with high priority of reduction control due to their having a margin of exposure (MOE) lower than 10,000. Risk assessment of exposure to ethyl carbamate, benzene and 3-MCPD showed MOEs higher than 100,000, indicating "safe". Dietary exposure to polycyclic aromatic hydrocarbons and benzopyrene was also found to be safe MOE levels >10,000. In addition, the results indicated safe MOEs (>1,000,000) for heterocyclic amines, nitrosamines, and biogenic amines. Most of the potential food contaminants were being kept at safe levels, however, it is necessary to continue to monitor and control exposure levels in accordance with the 'as low as reasonably achievable' (ALARA) principle.
