Korea ranks high among the OECD member countries with a high out-of-pocket share. In 2006, the government implemented in full scale the policy of extending the health insurance benefit coverage. Included in the policy are lowering the out-of-pocket share of patients of serious case and expanding the medical bill ceiling system to mention just a few. This study proposes to confirm effectiveness of the benefit extension policy by identifying changes in 'out-of-pocket expenditure as a share of the ability to pay' and 'incidence rate of catastrophic health care expenditure' of each individual household as manifested before and after the benefit extension policy was implemented. The 1st and 3rd year data from the Korea Welfare Panel Study (KoWePS), conducted by the Korea Institute for Health and Social Affairs (KIHASA), were used for the analysis, where low-income households and ordinary households are sampled separately. While the absolute amount of 'out-of-pocket expenditure' occurred to the average household increased for the period 2005-2007, the 'out-of-pocket expenditure as a share of the ability to pay' decreased. At the same time, the share decreased in the case of low-income households and households with patients of chronic or serious case as contrasted with ordinary households. 'Incidence rates of catastrophic health care expenditure' of ordinary households for 2007 stood at 14.6%, 5.9% and 2.8% at the threshold of 10%, 20% and 30%, respectively. The rates decreased overall between 2005 and 2007, while those of low-income households with patients of serious case statistically significantly increased. An analysis of this study indicates that it is related with the medical bill ceiling system regardless of incomes introduced in 2007.

This study explores the gender status of $Pok{\acute{e}}mon$ Series by analyzing the aspects of male/male-dominated $Pok{\acute{e}}mons$ and female/female-dominated $Pok{\acute{e}}mons$. Counting from the First Generation to the Seventh Generation $Pok{\acute{e}}mon$, there are 802 characters. Each $Pok{\acute{e}}mon$ has different gender ratio; the one $Pok{\acute{e}}mon$ could have more "possibility" to become male, female, equal, or genderless when he/she is born. This study examines those $Pok{\acute{e}}mons$ in three criteria: 1) Frequency 2) Stats 3) Diversification of Type, and it compares them based on their gender. $Pok{\acute{e}}mon$ Series is different than other video games as it provides many characters ($Pok{\acute{e}}mons$). Thus, it helps the audience to view the gender status of video game characters more closely and meaningfully.

The present study tried to provide useful data for the acoustic design of sound amplification system with measuring and analyzing subjective preference and intelligibility by varying the number of speakers and their directivity. The results suggest that the room absorption plays a key role in subjective responses of listeners and the large sound absorption of ceiling contributes to the increase of intelligibility. Also, larger number of speakers with narrow directivity improves perceived intelligibility when speakers were installed at the lower height. However, the highest degree of intelligibility and preference were obtained when speakers were installed close enough to the sound absorptive ceiling. The highest intelligibility and preference were observed when 8 to 10 speakers with the directivity of 60 degree were used.

Various pilotis are installed in the lower part of high rise buildings. Strong winds can generate sudden airflow around the pilotis, which can cause unexpected internal airflow changes and may cause damage to the exterior of the piloti ceiling. The present study investigates the characteristics of peak wind pressure coefficient for the design of piloti ceiling exteriors by conducting wind pressure tests on high rise buildings equipped with penetration-type and end-type pilotis in urban and suburban areas. The minimum peak wind pressure coefficient for penetration-type piloti ceilings ranges from -2.0 to -3.3. Minimum peak wind pressure coefficient in urban areas was 30% larger than in suburban areas. In end-type piloti ceilings, maximum peak wind-pressure coefficient ranges from 0.5 to 1.9, and minimum peak wind-pressure coefficient ranges from -1.3 to -3.6. With changes in building height, peak wind pressure coefficient decreases as the aspect ratio increases. Peak wind-pressure coefficient increases with taller pilotis. On the other hand, when piloti height decreases, the absolute value of the minimum peak wind pressure coefficient increases.

The purpose of this study was to determine the relationship between activities of daily living and health-related quality of life in ambulatory stroke patients. This was a cross-sectional survey study of 60 patients who had survived one year or more after a stroke in community. Activities of daily living were assessed using the Functional Independence Measure (FlM) and health-related quality of life using the Stroke Impact Scale (SIS). The association between FIM and SIS was examined using Pearson' s correlation. The FIM score was higher than the SIS score. Most domains of FIM exhibited a high rate (45-85%) of ceiling effects. However, only the communication and memory domain of SIS exhibited of ceiling effects. The correlation coefficients were .835 (p<.01) for FIM-motor vs. SIS-ADL, .257 (p<,05) for FIM-motor vs. SIS-communication, .596 (p<.01) for FIM-motor vs. SIS-social participation, .635 (p<.01) for FIM-cognition vs. SIS-memory, .369 (p<.01) for FIM-cognition vs. SIS-ADL, and .289 (p<.05) for FlM-cognition vs. SIS-social participation. In conclusion, the correlation between FIM-motor and SIS-social participation was higher than that of FlM-cognition and SIS-social participation. The domains of emotion and hand function of SIS showed no correlation coefficients with FIM-total. To examine the activities of daily living and the quality of life in ambulatory stroke patients in community, it is necessary to use both the FIM and SIS.

Recently, people are paying attention to new forms of construction. For example, deviated from an enclosed type space, people have been interested in an atrium type and an arcade type spaces. In this study, we had hypothesis 'Indoor thermal environment will be influenced by the inflow rate of natural lights with temperature and humidity.' We selected a multi-complex cultural center and conducted this study. This place is consisted of atrium, arcade, and enclosed types. The three spaces were classified according to the type of spaces that have own features along with their forms. The atrium type space has ceiling and the side windows, and the arcade type space has ceiling windows. On the other hand, there are no windows or open parts in the enclosed type space. Three measurement points at each space were selected because of their huge space. Intensity of illumination, temperature and humidity were confirmed by the average value of three measurement points. In addition, surveys were conducted regarding indoor comfort elements in each space.

Light-shelf is one of the most efficient natural lighting systems due to the improved function of the inflow level of the outdoor natural light. However, the existing research on the light shelf limits to the rectangular parallelepiped space, so do not provide sufficient data for various shapes of spaces. Thus, this study aims at deriving proper plan and relationship of the light shelf through its performance assessment depending on the indoor space shapes and utilizing them as basic data of light shelf design. The conclusions are as follows : 1) for 6m space depth, standard intensity of illumination satisfaction depth has shown 8.3%~26.3% improvement through the adjustment of the angle and width when installing light shelf compared to no light shelf installation; 2) $-30^{\circ}$, $-20^{\circ}$ and $-10^{\circ}$ light shelves set by this study play only as a blind regardless of the shape of ceiling on the summer solstice, and it is unsuitable; and 3) this study has derived proper plan of light shelf upon space shapes based on energy reduction and indoor evenness. The study results provide expanded data of the performance assessment of the light shelves according to the different space shapes and light shelf factors, which serves as a basis of the light shelves designing.

In this paper, we propose a the image-based automatic flight control system for the mini drone. Automatic flight system with a camera on the ceiling and markers on the floor and landing position is designed in an indoor environment. Images from the ceiling camera is used not only to recognize the makers and landing position but also to track the drone motion. PC sever identifies the location of the drone and sends control commands to the mini drone. Flight controller of the mini drone is designed using state-machine algorithm, PID control and way-point position control method. From the, The proposed automatic flight control system is verified through the experiments of the mini drone. We see that known makers in environment are recognized and the drone can follows the trajectories with the specific ㄱ, ㄷ and ㅁ shapes. Also, experimental results show that the drone can approach and correctly land on the target positions which are set at different height.
