The domestic casino industry is attempting to change from the existing single form to the advanced-type of complex casino resort. In addition, the importance of the security management system, which prevents and responds to accidents caused by negative influences of gambling, is emphasized at the casino enterprise level. Therefore, this study aimed to find measures to revitalize the security management system for domestic casinos only for foreigners through an analysis of relevant literature and case studies. As a result of the analysis, it was found that in order to effectively cope with changes in the casino industry, three areas were needed to be revamped: (1) a lack of protocols which intend to protect casino security personnel, (2) an inefficient operational system due to the dualized casino security management system, and (3) a lack of systematic educational system for casino security personnel. This study therefore proposed three measures: (1) a review of revisions of related laws to protect casino security personnel, (2) enhancement of professionalism of casino security personnel and (3) establishment of a single operating system of the casino security management operating system.

The first priority we face in the conservation of wall paintings, is the conservation of painting layer. The 'painting layer' is sometimes called the pigment layer, and refers to the painted surface. For the consolidation of this painting layer we use 'fixative'. Fixative is a common adhesive which has been used in various field and conservators have made up for the weak points in the consolidation of wall paintings. In my thesis, I will summarise the range of use, standards of selection, and results of research on the use of fixative in the conservation of European paintings. In addition, I will describe various kinds of our traditional fixatives. As synthetic resins have proved that it is not ideal as a fixative for wall painting, conservators have studied to find an alternative. Same as European conservators, Asian scientists has researched to find alternative fixative which is more suitable to the wall paintings in Asia based on their traditional techniques and materials. Therefore, 1 have studied to find an adequate fixative for our own wall paintings and I could conclude that we can consider traditional fixative which is made of 'seaweeds' as an alternative and it is very important to proceed research and experiment on this material.

This study aims to investigate the safety instrument to prepare the policy alternative for social web-board game which will be developed to base on social network in the future although social casino game is not available in Korea now. We reviewed several literature about responsible game system applied to especially U.S. New Jersey, responsible gambling system acted in the being advanced all countries. Game experts built up user protection model as previous work to prepare the law and policy which such a responsible game system will apply for current web-board gaem and future social casino game. As a result, this research revealed that standard of judgement which can identify four kind of addiction danger user group are raised. We expect to help this user protection alternative to provide the law and policy instrument for future social casino game and complement the problem of current web-board enforcement.

The purpose of this study is to examine the recovering gambling addicts' overcoming process on their hardships of life which hamper their recovery. For this study, we had one to one depth interview with 10 participants who had overcome their hardships of life after stopping gambling. The data gathered from the interviews were analysed following the grounded theory process suggested by Strauss and Corbin. As a result, 131 concepts were constructed, and they were classified into 32 subcategories and 14 category. We presented "overcoming of the hardships of life through the acceptance of reality and re-determination" as a core subject which connects the whole concepts. Based on the research outcomes, we proposed some policy and practice intervention methods such as economic self-support program, social security service, and triangle support system by counselor-family-peer recovering addicts.

The purpose of this study is to classify the degree of change of job discrimination of the disabled according to time and to identify factors affecting life satisfaction according to each type. For this study, data from the 3rd to 8th year of the employment panel for the disabled were used and 1,227 data were used. The longitudinal profile of the disabled person's discrimination was classified through latent profile growth analysis(LPGA), and then influential factors were verified through binomial logistic regression analysis. First, the types of change of the job discrimination of the disabled were represented as the decrease group and the increase group. The factors influencing the job discrimination were the degree of disability, chronic diseases, gross income, and life satisfaction. Second, the factors of predicting the life satisfaction according to the types of job discrimination of the disabled are as follows: job discrimination, decrease and increase group have higher life satisfaction as the self - esteem and socioeconomic status are higher. Based on these results, this study suggested the implications of this study to cope with the discrimination of the workplace with the disabled.

We investigated the relationship between morphological characteristics and individual dry weight to develop a method for estimating the individual dry weight of sheet form macroalgae: Ulva australis, Ulva linza, Pachymeniopsis lanceolata, and Pyropia yezoensis. In Total, 319 thalli of various sizes were collected at six sites from February 2017 to December 2018. An interspecific allometric exponent of 0.28 was found for length-biomass allometry in four sheet form macroalgae, corresponding to a 1/4-power law for primary producers. The relationships between surface area and individual dry weight, as well as between individual fresh weight and individual dry weight, were found to fit significantly using linear regression equations. This explained 94-99 % of individual dry weight, indicating that surface area and individual fresh weight can be used to accurately estimate individual dry weight. We propose the use of this method when experimental processes do not allow individual dry weight to be measured directly, so researchers can save both time and expense.

In this study, the possibility of using marine life for cosmetic materials was assessed by establishing a fermentation process of seaweed, such as Ecklonia cava, Enteromorpha prolifera, Chondria crassicaulis, Eiseniabicyclis, Codium fragile, Seaweed furcata, Gloiopeltis tenax, Grateloupia elliptica, Undaria pinnatifida, and Saccharina japonica. Lactobacillus sakei isolated from Kimchi was used for effective fermentation and whole milk powder was used as an additive. 2.0 % of crushed seaweed and 1.0 % of whole milk powder were added and afterwards, 1.0 % Lactobacillus sakei was added after cooling to $40^{\circ}C$. After cooling and filtering the fermented product, butylene glycol, glycerine, and 1,2-hexandiol, which have the effect of a preservative, were added to mix and complete the final product. Among the ten kinds of seaweeds, the process was found to be highly effective in the fermentation of Ecklonia cava, Codium fragile, Undaria pinnatifida, and Saccharina japonica. The amount of fermentable substances in cosmetics was determined and the safety of the raw material was verified using the HET-CAM (The Hen's egg test-Chorioallantoic membrane) test.

As military service members are fully permitted to use mobile phones for sickness after work, it is time to minimize the direct collection of personal information from telecommunication companies when opening mobile phones to secure the safety of military service personnel's personal information. Prior to introducing the use of mobile phones by soldiers after work, the Ministry of National Defense established a security control system such as blocking the mobile phone shooting function to prevent security accidents and concerns about some adverse functions such as illegal cyber gambling, game addiction, and viewing pornography. come. Mobile telecommunications companies entrust personal information processing tasks, such as opening mobile phones, to telecommunications agencies and carry out management and supervision, such as checking the status of personal information protection measures. When a military service member opens a mobile phone, a personal information management agency is newly established using the right to portability of personal information, and a system for requesting the transmission of personal information from the military service member is proposed.
