The number of 1 or 2 households is rapidly increasing due to the participants of women in the working society, the increment of unmarried men, and the change in family structure. The current housing market and the housing administration focuses more on the bigger number of households so that single person households are being neglected. As more individuals move to the capital, living in the city for a single person household has become very difficult. Sharing has become an important aspect among the society and shared housings have hit the minds of single person households as a new way of living. Comprehensive properties, boarding houses, housings for studying (Go-Si-Won), and officetels match the ideas of shared housings. The absent of clear standards on private rooms and shared facilities is making the living very challenging. This study aim to understand foreign (England, Australia, and Japan) institutional characteristics for shared housings to build foundations in order to bring in shared housings into Korea. The residential concept can not be applied to shared housings in Korea directly since the idea of living is different for each nation and its cultural distinctions. However, a clear classification and standards on shared housings depending on the size of the house and number of residents are needed alongside with an index of principles and residential criteria.

In this paper, we propose a correction method for astronomical telescope using recursive least square method. There are two ways to move a telescope : equatorial operation and altazimuth operation. We must align polar axis of a equatorial telescope with the north celestial pole and adjust the horizontal axis of a altazimuth telescope exactly to match the celestial coordinate system with the telescope coordinate system. This process needs time and expertise. We can skip existing process and correct a tracking error easily by deriving the relationship of the celestial coordinate system and the telescope coordinate system using the proposed correction method. We obtain the coordinate of a celestial body in the celestial coordinate system and the telescope coordinate system and derive a transformation matrix through the obtained coordinate. We use recursive least square method to estimate the unknown parameters of a transformation matrix. Finally, we implement a telescope control system using a microprocessor and verify the performance of the correction method. Through an experiment, we show the validity of the proposed correction method.

Basketball is a highly complex sport, analyses offensive and defensive rebounds, free throw percentages, minutes played and an efficiency rating. These statistics can have a large bearing and provide a lot of pressure on players as their every move can be analysed. Performance analysis in sport is a vital way of being able to track a team or individuals performance and more commonly used resource for player and team development. Discovering information such as this proves the importance of these types of analysis as with post competition video analysis a coach can reach a far more accurate analysis of the game leading to the ability to coach and correct the exact requirements of the team instead of their perceptions. A significant difference was found between winning and losing performances for different types of turnovers supporting current research that states that turnovers are not a valid predictor of match outcomes and that there is no specific type of turnover which can predict the outcome of a match as briefly mentioned in Curz and Tavares (1998). Significant differences were found between winning and tied and losing and tied performance for some types of turnovers, however due to the lack of data collected in this area they cannot be considered valid. Further research could also be conducted in other areas relating to performance indicators where there is currently minimal research in some areas such as assisted baskets, stated about the performance indicators in their own study the performance indicators are inadequate for explaining the complexities of the game suggesting that one indicator will not be constant in every game an research into performance analysis areas would be more appropriate.

The foreign superior players and national team players' turning phase was measured, compared and analyzed to help the representative players improve the skill of turn. The underwater video camera used to analyze and evaluate the representative players' skill of turn in detail and the result is as follows. 1. The record for the phase of turn was similar to the rank of the last record. The improvement of the skill of turn was required because Korean players' record was lower than the foreign players' one. In case of 200m events the 1st turn was the fastest and it took more time as the turn is repeated. 2. It shows that the preparation phase and turing motion cause the difference between the players and within one player. 3. The horizontal movement of center of gravity moves to turning point slowly in the preparation phase, does not move nearly in the turning phase and increase again in the propulsion phase. Good record has short time for turn phase. The result means that the shorten the turning phase is the most important factor. Therefore the preparation for this is required. The vertical movement is maintained or increase a little and then move to from the turning phase. 4. The characteristic of horizontal velocity in center of gravity is that there is any big changes at the preparation phase, the faster velocity is found from the better record and the accelerating time is fast at the propulsion phasen. The wrong motion is made by not using the swimming velocity for fuming and waiting and more time is required by this. 5. The angle of knee when the player touch the turning point is 106.22-135.56 and the maximum angle of knee during the driving after the touch of tuning point is full extension. The size of maximum angle of knee did not match with the required time of propulsion phase. It seems that the individual difference is big when the players touch the turning point the angle of knee and the research for the individual angle which can reveal the maximum power should be carried out. The national team player's skill for the him is behind the foreign players' one and a lot of problems were found. It shows that the players could not practice the skill for turn during the training. The 1st reason for it is the various facilities like underwater window or analyzing equipment like underwater camera with which the coaches can teach and correct the players' detailed skill. It is need to evaluate the players' detailed skill exactly and correct it by objective data to complete the good skill in the future. In this regard, the investment for the facility is necessary.

Everything of the world we live in has its own unique color. Those colors move us, enrich our every day life, and make us happy. When we have our hairs dyed by a color we like, we may look different, feeling confident and activated. We select a color fur our hair color design depending on such symbolic aspects as our life styles, self-images or personalities. Namely, we tend to choose a color the image of which we like. Such a tendency implies that it should be important to study hair colors in multi-faceted ways. The purpose of this study was to survey people's preferences of hair color tone images depending on their demographic and physical variables and thereby, determine the correlations between their preferences and variables. For this purpose, hair colors tones were classified into 11 categories and thereby, subjects' preferences of hair tones were analyzed in terms of the image adjective combinations. The results of this study can be summarized as follows; As a result of analyzing subjects' preferences of hair color tones depending on their such demographic variables as gender, age group and marital status, it was found that males tended to prefer dark tones more than females, and that those in their 30's or older tended to select dark tones more than those in their 20's. On the other hand, the married preferred medium bright tones more than the singles. Furthermore, such physical variables as body size, weight and apparel size were found correlated with hair color tone preferences. To be specific, shorter people desired more to have their hair colors match with their natural ones not to be less exposed to others. Lastly, as a result of analyzing the correlation between hair color tone preferences and weight and apparel size, it was found that fat people tended more to prefer medium bright color tones than normal or slim people.

General drug prices involve three stages: shipment stage, wholesaler stage and retail stage. Policies on drug price differ from country to country. Shipment stage prices are tightly regulated in countries like France and Netherlands. They are free in only a minority of advanced countries, even if these include some major players such as the US, Germany and, in a very limited sense, Japan. The situation in the UK is very complex with a semi-free system, where drug companies are free to set their own prices but cannot exceed a predetermined profit ceiling. Mark-up at both wholesaler and retail stages is formally admitted in most countries observed. Apart from the general drug prices, reimbursement price of insured drugs has been major policy concerns. Most countries reviewed in this study has exerted some control over reimbursement prices, but differ both in the way how and in the extent to which prices are admitted or fixed. Price fixing has been used in France and Japan. Some countries have transformed their system over time, particularly to move to reference pricing in the last decade. This mechanism has empowered the customer, and improved price competition on the market. Referring to the drug price policies in the advanced countries, this study makes some suggestions for the redirection of Korean price policy for reimbursement drug in health insurance as follows: to match appropriate policy tools to each policy goal; to maximize market mechanism through effective reimbursement price fixing which admits mark-ups in wholesaler and retail prices; to introduce reference pricing system in order to redirect patient's demand with a financial incentive to choose the best-priced drugs and to save the finance of health insurance; and to strengthen surveillance and monitoring mechanism in the drug market.

This study was conducted to analyze the wearing condition on gloves for pilots and to suggest the developments for pilot gloves design. This survey was performed with 99 pilots and the questionnaires included items about discomfort, materials and problems when wearing pilot gloves. The respondents felt uncomfortable on the finger tip, the hollow area of the hand and the end of thumb when they move their hands with the gloves. They replied that the finger length, palm length, and circumference of the fingers did not match well. Also they complained there was severe abrasion in the tip of the thumb, finger tips and the middle of the palm of the gloves. The result of these analyses supports the following suggestions. It is necessary to improve durability by applying the additional materials to the severely worn parts. Punching on the glove materials could improve sweat rate and ventilation, and careful washing should be accompanied to prevent the occurrence of linters and transformation after laundering. And it is needed to prepare an accurate and more diversified size system and to design the gloves fitted to the individual hands. With these in mind, it is required to propose solutions for pilot gloves with reference to the survey results in order to design appropriate pilot gloves in terms of movement, size and material. It was concluded that an analysis of the wearing condition and developments are useful for ergonomics pilot gloves design.

Camera pose and scene geometry estimation from video sequences is widely used in various areas such as image composition. Structure and motion recovery based on the auto calibration algorithm can insert synthetic 3D objects in real but un modeled scenes and create their views from the camera positions. However, most previous methods require bundle adjustment or non linear minimization process [or more precise results. This paper presents a new auto' calibration algorithm for video sequence based on two steps: the one is key frame selection, and the other removes the key frame with inaccurate camera matrix based on an absolute quadric estimation by LMedS. In the experimental results, we have demonstrated that the proposed method can achieve a precise camera pose estimation and scene geometry recovery without bundle adjustment. In addition, virtual objects have been inserted in the real images by using the camera trajectories.
