Waste recyling is a very important concept with waste minimization in the waste managment. Especially, recycling waste from the point of environmental and economical view is useful. The recycling part of package waste needs to continuously grow. But, cosmetic container, which is continuosly increased as waste. The difficulty of waste treatment in cosmetic industy produces complicated environment problem. Cosmetic container is difficult to recycle because it mostly made of complex material. Also, cosmetic container is difficult to separate I source and thus usually are generated mixed waste. In this study we performed an analysis on the Recycling Improvement method of a Cosmetic Container The result of this study could be summarized as follows 1) As a part of law and a system improvement, must be achieved Improvement Cosmetic law, Deposit refund system. and charge system, Technology development for recycling of a cosmetic container, Extension of refill productions, Recovery system establishment of a cosmetic container and inducement of a maker's recycling paticipation. 2) As a part of a cosmetic container design improvement, must be achieved simplification and standardize of container's cuality, Cosmetic life cycle extension, Selection of recycling materials and Cosr reduction of a cosmetic container. In conclusion, To the recycling improvement of a cosmetic container, must be achived collective development of system improvement, participation of the government and company and a consumer's recycling consciousness. Most of all, A company need to try to recycling container development of a cosmetic container.

Purpose - In align with the increasing competition in both online and offline franchise markets caused by the increasing impact of social networking service, entrepreneurial passion(EP) of the franchise owners has crucial impact on the stakeholders. This study proposed the customer among stakeholders has the critical influence firm's success and examined the structural relationship between entrepreneurial passion(EP) and trust, identification, and loyalty from the customer's perspective. Research design, data, and methodology - This study examines the structural relationship between entrepreneurial passion(EP), trust, identification, and loyalty from the customer's perspective. More specifically, the EP were measured using three sub-dimensions such as EP-inventing(Perceived passion for inventing), EP-founding(Perceived passion for foundting), and EP-developing(Perceived passion for developing). In order to verify the research purposes, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. Each item was measured on a 7 point Likert-scale anchored by '1 = strongly disagree, 7 = strongly agree'. The data were collected from 449 franchise consumers through online survey and were analyzed using SPSS 21.0 and Smart PLS 3.0. statistical program. Result - The results of this study are as follows. First, EP-inventing and EP-developing have significant impacts on corporate trust. Second, EP-founding does not have significant impact on corporate trust. Third, EP-inventing and EP-founding have significant impacts on consumer identification. Fourth, EP-developing does not have impact on identification directly, but does indirectly through corporate trust as a mediator. Fifth, corporate trust and identification have significant impacts on loyalty. Conclusions - This indicates that the foodservice franchise CEOs should continuously develop new menus and service to fulfill customer needs. EP-inventing of the food franchise CEOs may enhance customer trust for higher quality of product or service, and EP-developing can also be a driving force for customer trust as it embeds belief in customers that the franchise is sustainably developing. Also, food franchise CEOs should first clarify the support process for the existing brands before developing new ones. Customers tend to lead the trend by using brands that satisfy new trends in the foodservice franchise market, and it could have identification with the trend-setting franchise. Customers do not accept if a company is different from their personal image or norms. So the franchise CEOs must create identification with customers by building corporate trust. Corporate trust influences consumer behavior and emotion, thus the franchises need to secure trust by improving product or service continuously.

Recently, the problems in school violence did not stop on the crime between the members at the school and which developed into the invasion crime of the school caused by outsiders. The school is no more the safety zone from the crime. Particularly, in the case of the elementary school, because there are nearly no people who oppose to the outside attacker and can control this, it is the place where it is vulnerable to the invasion crime. The Metropolis of Seoul implements the School Sheriff system within the jurisdiction bureau, in the public elementary school. However, actually the School Sheriff business is being managed, never applying a rule in the Security Industry Law with the main content, that is the Security Industry Law application is excluded. Because the jurisdiction on the contract of Seoul City and operating company are run, the various issues is caused. First, since it is not being considered as a security business, the commercial liability insurance for security company has no chance to applicate when the operation company and the School Sheriff have related damage generation. So the security for the indemnification of loss of the victim is weak. Second, The task of the School Sheriff is ruled just by in the individual contracts. But it is insufficient with this thing. The related duties are required some supplement like a general rule application including the obligation of the guard in the security industry law. Third, the education of the School Sheriff needs to connect with the educational programme in the security industry law. The related professional education specially needed for the prevention of school violence ought to be reserved compensation. Forth, the citizens still demand the strengthening of police patrol for the surroundings of a school in spite of the result of Seoul City's public survey. Therefore, the active relation of cooperation with the police needs to be supported legally and institutionally with the Security Industry Law application. Fifthly, the success of the School Sheriff business can be more guaranteed with the supervision of the legal and institutional device like a the Security Industry Law application or police and all sorts of administrative execution's and etc.

This study analyzed the issue and limit of artists's Welfare Law. The issue is about artists' labor, their status, and the process for buying social insurance. In this study, we used the literature method the existing data collection clean up, analysis, and evaluating. The solution plan for the vitalization of the guarantee of social insurance for stage actors is as follows. First, based on social insurance law, is to grant an exceptional status to stage artists. Second, the process for buying social insurance has to be changed to posterior judgement by Ministry of Culture, Sports, and Tourism after buying social insurance through Ministry of Employment and Labor. And when a theater company as a leaseholder rent a theater, it should be mandatory for it to get existing industrial accident compensation law. As a new numerical formula, there are an unemployment insurance numerical formula considering distinct characteristics of artists' labor and a formula of calculating insurance fee for industrial accident compensation. Last, there needs to be an introduction of exceptional method allowing a preparatory period for the production of a play and stage actors' side job.

When a financial time series consists of daily (closing) returns, traditional volatility models such as autoregressive conditional heteroskedasticity (ARCH) and generalized ARCH (GARCH) are useful to figure out daily volatilities. With high frequency returns in a day, one may adopt various multivariate GARCH techniques (MGARCH) (Tsay, Multivariate Time Series Analysis With R and Financial Application, John Wiley, 2014) to obtain intraday volatilities as long as the high frequency is moderate. When it comes to the ultra high frequency (UHF) case (e.g., one minute prices are available everyday), a new model needs to be developed to suit UHF time series in order to figure out continuous time intraday-volatilities. Aue et al. (Journal of Time Series Analysis, 38, 3-21; 2017) proposed functional GARCH (fGARCH) to analyze functional volatilities based on UHF data. This article introduces fGARCH to the readers and illustrates how to estimate fGARCH equations using UHF data of KOSPI and Hyundai motor company.

Control chart is representative tools of statistical process control (SPC). It is a graph that plotting the characteristic values from the process. It has two steps (or Phase). First step is a procedure for finding a process parameters. It is called Phase I. This step is to find the process parameters by using data obtained from in-controlled process. It is a step that the standard value was not determined. Another step is monitoring process by already known process parameters from Phase I. It is called Phase II. These control chart is the process quality characteristic value for management, which is plotted dot whether the existence within the control limit or not. But, this is not given information about the economic loss that occurs when a product characteristic value does not match the target value. In order to meet the customer needs, company not only consider stability of the process variation but also produce the product that is meet the target value. Taguchi's quadratic loss function is include information about economic loss that occurred by the mismatch the target value. However, Taguchi's quadratic loss function is very simple quadratic curve. It is difficult to realistically reflect the increased amount of loss that due to a deviation from the target value. Also, it can be well explained by only on condition that the normal process. Spiring proposed an alternative loss function that called reflected normal loss function (RNLF). In this paper, we design a new control chart for overcome these disadvantage by using the Spiring's RNLF. And we demonstrate effectiveness of new control chart by comparing its average run length (ARL) with ${\bar{x}}-R$ control chart and expected loss control chart (ELCC).

The One-Time Password(OTP) Generator is used as a multi-factor authentication method to ensure secure transaction during e-Financial transaction in the bank and securities company. The OTP based e-Financial Transaction Verification Protocol ensures secure e-financial transaction through confirming the user's identity using OTP authentication information and counters not only Man-in-the-Browser(MITB) attacks but also memory hacking attacks. However, it is possible to generate correct OTPs due to potential of stealing sensitive information of the OTP generator through intelligent phishing, pharming, social engineering attacks. Therefore, it needs another scheme to prevent from above threats, and this paper proposes advanced scheme using Physical Unclonable Functions(PUFs) to solve these problems. First, it is impossible to generate the same OTP values because of the hysically unclonable features of PUFs. In addition, it is impossible to clone OTP generator with hardware techniques. Consequently, the proposed protocol provides stronger and more robust authentication protocol than existing one by adding PUFs in the OTP generator.

Innovation is the development of new customers value through solutions that meet new needs, inarticulate needs, or old customer and market needs in value adding new ways. This is accomplished through more effective products, processes, services, technologies, or ideas that are readily available to markets, governments, and society. Innovation differs from invention in that innovation refers to the use of a better and, as a result, novel idea or method, whereas invention refers more directly to the creation of the idea or method itself. Therefore, the utilization of patents is the most important of the three aspects (creation, protection and utilization) in the patent system for getting to actual innovation. In order to increase the patent use, the rates of the applied patents to a real industrial process and the bargain and license of patent rights should be promoted. For promoting technological innovation substantially, there is necessary to escape from dichotomy of weakening or enhancing patent protection in the discussion on the changes of patent system for "Adequate patent guarantees". Furthermore, the legal and institutional improvements to enable the use of patent should be discussed together. Recently, open innovation is a new paradigm that assumes that firms can and should use external ideas as well as internal ideas, and internal and external paths to market, as the firms look to advance their technology" or "Innovating with partners by sharing risk and sharing reward." The boundaries between a firm and its environment have become more permeable; innovations can easily transfer inward and outward. The central idea behind open innovation is that in a world of widely distributed knowledge, companies cannot afford to rely entirely on their own research, but should instead buy or license processes or inventions (i.e. patents) from other companies. In addition, internal inventions not being used in a firm's business should be taken outside the company. In the era of open innovation, more flexible patent use strategy is essential. It is important that improvements for the legal system in order that patented technology can be applied for products and processes in a real industrial between outside and inside of the firms.

This study aims to propose efficient way to operate the security guarding system from the perspective of administration, policy, law, institution and operation as to the private security guarding system as the Korean security guarding system needs multifaced analysis and measure to ensure efficient operation. The growth strategy has to be restructured and segmentation market needs to be driven in order to cope with the changing conditions of company from the perspective of administration. And private security guarding service companies must refrain from excessive competition while improving the contracting method such as minimum price bidding, etc. From the perspective of policy, the functions of relevant organizations such as the National Police Agency, security association, etc, and mutual cooperation must expand. Also, the profit generation event needs to be privatized and the more positive perception toward the private security guarding service is necessary. In addition, security exhibition and seminar can be expanded to lay the groundwork for the advancement of private security system. From the legal and institutional perspective, the security guarding service related law must be revised and the certification system must b introduced to cope with the changing requirement. The security guarding instructor system must be strengthened to ensure a faithful and earnest implementation of duty to instruct, supervise and educate security guarding personnel. From the perspective of security guarding system's operation, professional security technique must be introduced and applied, and the volunteer application system must be established. In addition, standard 'security guarding manual' must be crafted, and the equipment for security guarding must be modernized to ensure an efficient operation of private security guarding services.

The consumer's expectation of companies' social responsibilities has been continuously getting higher as the consumerism has been matured. So, the company has faced the shift to move forward to the positive social activity such as charity, donation, and sponsorship. In addition, the company which does make a success needs to reach goals not only to maximize profits but also to make justices of social and cultural boundaries. Thus, success of an enterprise aims at the maximization of profits as the economic objective and the creation of competitive, powerful brands. Accordingly, as enterprises consider social responsibility as the concept of effective investment to enhance the asset value of corporation, they seek to extend their brands in order to pursue cause-related marketing, which accomplishes and complements two objectives each other the performance of social responsibility and the pursuit of powerful brand assets. In Korea, there are traditional ritual ceremonies such as ceremonies of coming-of-age, marriage, funeral, and ancestor worship and they consider those ceremony occasions as very important. Moreover, social positional grade of rank like the two upper classes of old Korea made people pretend to be noble and sensitive to other people around themselves. This old custom could influence Korean people's way of life, especially, consumer-action. This deep rooted custom also could influence consumption life considerably. Through this study, we can understand the consumer behaviors of Korean who consider ritual ceremonies and saving face as essential and are influenced by this culture. on another hand, we intend to check the effects on buying luxury brands.
