This study aims to investigate the transition of the game rating system in Korea and to search for problems and improvement measures in the era of IARC game grade review. IARC(International Age Rating Coalition) is an International Classification Alliance, with 37 member organizations from 6 countries. In addition, IARC grants participating store-fronts autonomy to review game ratings. The method of deliberating games in Korea is proceeding with direct review by rating system and deliberation by IARC's own classification system. The problem of the rating system of the game is that the civilian becomes the subject, it relies on the questionnaire, and its side effects are caused by its own classification system. IARC guidelines can be developed to improve the game rating system, education on penalties and ratings for game developers, and management of participating front-stores. In conclusion, it may be dangerous to delegate rating authority to open market, and it is necessary to construct a discussion forum for ratings, including government and industry, game developers, users, and parents of under-age gamers. It is necessary to create a rating system for the game environment in Korea.

The purpose of this thesis is to develop a performance rating training tool for the time and motion study. It is widely recognized that rating training tools based on films were made several decades ago and introduced to Korea. However, to the best of our knowledge, those films are not used for rating training in Korea any more. Furthermore, although rating is still important method for the efficient operational management study, it is briefly mentioned without any training or exercise. In this paper, we propose a simple rating training tool based on Excel with VBA. The mottoes of our development are the ease of acquisition and trainees' motivation. Test results show that trainees can obtain the concept of rating and the ability of accurate and consistent rating as they play a computer game sitting in front of the personal computer.

The current housing performance rating system displays the performance rating of the houses supplied by the housing construction company, approved by the Housing Law. This system is intended to provide accurate information to the consumers in the announcement of the tenant recruitment, thereby improving the quality of the housing. This system was revised in January 2005 and implemented from January 2006. It is obligatory for companies with a scale of more than 1,000 households (energy performance rating is over 300 households), but there is currently no content on the waterproofing field. Therefore, this study suggests the revision plan proposes the necessity of the inclusion of the performance grade for the waterproofing field which is not currently implemented in the apartment house performance rating system, and to understand how to secure an adequate living environment. As a result, according to survey results, the performance score based on the difficulty of the maintenance method according to future leaks was selected and the revised system was prepared. Based on this, the performance grade for the virtual apartment was evaluated, and the results show that the performance of various grades is presented accordingly.

The measuring apparatus such as heat meter is legally obliged to be installed and used for heat rating with heat or flow rate in residential buildings in Korea. There are two kinds of apparatus to measure heat consumed at each households, i.e., heat meter and hot water flowmeter. Contrast to the most of buildings with hot water flowmeter well being used for rating, heat meters have been used only 42.6% in the buildings with central heating system. But there is a critical problem in the course of using hot water flowmeter for heat rating, yielding distorted and unfair result which is different from the real value of heat supplied. Experiments with several parameters were carried out in this study to analyze this phenomenon quantively and alternative methods were proposed for rational heat rating.

In collaborative filtering systems, the item rating prediction values calculated by the systems are very important for customer satisfaction with the recommendation list. In the time-aware system, predictions are calculated by reflecting the rating time of users, and in general, exponentially lower weights are assigned to past rating values. In this study, to find out whether the influence of rating time on the rating value varies according to various factors, the correlation between user rating value and rating time is investigated by the degree of user rating activity, the popularity of items, and item genres. As a result, using two types of public datasets, especially in the sparse dataset, significantly different correlation index values were obtained for each factor. Therefore, it is confirmed that the influence weight of the rating time on the rating prediction value should be set differently in consideration of the above-mentioned various factors as well as the density of the dataset.

While the local health insurance and the employment-based insurance were integrated in July 2000, the insured is divided into employment-based insured and the local insured and the relevant premium has been applied to both groups. The health insurance premium having the feature of social solidarity has to be determined depending on income, that is, the ability to pay in accordance with the principles of social insurance. While employment-based insurance premium has been determined depending on the earned income, the local insurance premium for the local insured has been determined by scoring gross income(evaluated income), property and possession of automobiles. A variety of improvement approaches has been implemented including introduction of the employment-based insurance premium ceiling system (2002) and the change of property scoring system for the local insured (2006). However, the health insurance system which was merged in 2000 has been implemented up to now without significant change even though there were lots of socio-demographic change including increase of income level and the population structure such as low birth and aging. In other words, it is required to implement the premium rating system securing the income-based equity. Nevertheless, it was inevitable to apply the diverse rating standards in the early stage because it was very difficult to verify the income of the self-employed. Although the income verification rate was significantly increased from 23% in 1989 to 44% in 2010, the irrational standards including property, automobiles, living standard and activity rate have been still applied to the local insured because it is difficult to secure the validity of insurance premium rating system and it severely lacks of security. This paper investigated whether the current insurance premium rating system for the local insured imposing the premium on the basis of 'gender' and 'age' complies with the basic human rights secured by the current Constitution of the Republic of Korea with respect to the practical and theoretic irrationality of insurance premium rating system and standards for he local insured. In accordance with the analysis results, this paper proposed the approach to improve the system.

Recently an intelligent system is developed for the service what users want not a passive system which just answered user's request. This intelligent system is used for personalized recommendation system and representative techniques are content-based and collaborative filtering. In this study, we propose a prediction system which is based on the techniques of recommendation system using a collaborative filtering and a fuzzy system to solve the collaborative filtering problems. In order to verify the prediction system, we used the data that is user's rating about movies. We predicted the user's rating using this data. The accuracy of this prediction system is determined by computing the RMSE(root mean square error) of the system's prediction against the actual rating about the each movie and is compared with the existing system. Thus, this prediction system can be applied to base technology of recommendation system and also recommendation of multimedia such as music and books.

Plenty of efforts have been made in the traditional architecture of Korea, Hanok, to develop various elements such as restoration, the introduction of new design, and energy-saving while systemic setups on standard and evaluation of eco-friendly energy design of Hanok are lacking. If we evaluate energy performance based on current standards without reflecting unique features of Hanok on the system, Hanok will be included in the very low grade among the residential buildings being included in the approval system of eco-friendly architecture or the unique features will be modified and the burden of increased construction cost. Therefore, this study is to prepare the basic reference for the introductory evaluation system by evaluating the energy performance level of NEO-Hanok based on the current building energy rating system. The result for NEO-Hanok based on the building energy rating system, we propose the rating standard with scorecard elements of NEO-Hanok by considering the necessity of identity and standard for NEO-Hanok. As a result of infiltration test to check the tightness, it was measured as 10.81 times/h (50 ACH). As we switch from the main insulation for the wall from the glass wool 64k(0.035W/mk) to rigid polyurethane foam first class first unit (0.024W/mk), the result was slightly increased from the first demand quantity rating yield $249.8kWh/m^2{\cdot}yr$ to $235.0kWh/m^2{\cdot}yr$. Current certificate system is focused more on the heating load than the cooling load, it is disadvantageous for Hanok, which has less cooling energy consumption in summer. The rating result from the target building study is level 4.
