This study was performed to investigate the effects of receiver's moving speed and pass types on anticipation timing response. Ten subjects were required to make a total of 24 passes in coincidence with an experimentally manipulated moving light signal in randomly three different conditions by performing chest and bound pass. Results of analyses revealed AE, CE, and VE increased as moving velocity became constant-acceleration condition. In addition, chest pass was more accuracy and consistency than bound pass on AE and CE. These findings indicated that moving velocity and pass type served as the major determination of coincident timing response on passing in basketball.

Apartments have become the most popular type of residential building in Korea since the 1960s. The dwelling space should be designed to accomodate various life styles or changing needs of family members. This research is conducted to analyze flexible interior space types of apartments and to improve the architectural planning and design of apartments that can satisfy various needs of residents. In this study, apartments of 10 - 90 pyeongs built in the region of Seoul, between 1998 and 2007, are investigated in terms of the unit plan, the number of open sides, and a distribution of flexible apartment types for each year, Apartments with flexible space are classified into 10 different types, including a flexible type between bedrooms, a flexible type between a bedroom and the livingroom, and a flexible type between the dinning room and the livingroom. According to the composition of unit plans, apartments are also differentiated as a single-corridor type, a double-corridor type, a stairway type, a hall type, and a combination type. According to these classifications, the characteristics of desirable unit plans were analyzed. The results of the analysis showed that, as the unit size of apartments get bigger, the ratio of width/depth of the front side unit plan is increased. This result reflects a trend of high-rise apartments which have an increased number of front-side bays and a shorter depth for better penetration of daylight. In addition, a hall type is found to have a wider front side and shorter depth. According to open sides, a flexible type of the livingroom and the dinning room/kitchen (L-D.K) is found to be most common for the front/back open space, and the livingroom is usually placed on the front/side open space. To meet the changing needs of residents, more research should be conducted on flexible dwelling space.

This thesis is based on the study of formativeness and versatility of Sarong. For the aim of the research, Sarongs were classified into two types: rectangular and tube, using its original form as the basis. These two types of Sarongs were divided into more detailed groups depending on the purposes of attire, such as skirts, dresses, and capes. To look into the formativeness and versatility of Sarong, the usage of wear and expression methods were observed based on these categories. The following results were found regarding the versatility of Sarong: First, Sarong has a wide degree of versatility in terms of usage. It can be worn as a skirt, a head scarf, a dress, a cape, or used as a carrier or even a sleeping bag, based on one's intention. The change of usage is often accompanied with the change of forms, as can be shown by the longyi of Myanmar, the tube type Sarong, which is used as briefs. Second, Sarong has a wide degree of versatility in terms of function. Variations of instrumental and expressive function of Sarong are observed simultaneously. The physical function sometimes coincides with the changes of usage as mentioned above. The way that Sarong's are expressed in different social situations changes depending on the wearer's social status, religion, or origin. So by looking at the way a Sarong is worn, others can tell if a person is going to social events such as festivals and weddings. Third, Sarong has a wide degree of versatility in terms of design. However, even if same usage and function is pursued, the design can be different based on an individual. This is because the external change of Sarong is affected by individuality or aesthetic sense of the wearer.

With the current rapid changes in population and technology, the long-lastig housing certification system is a means of prolonging the physical and functional lifespan of a building. The certification requires differentiation between the structure and infill elements to allow for variability and ease of repairs. This works well with prefabricated houses so this study investigated the possibility of applying the long-lastig housing certification requirements to apartment construction using off-site construction (OSC) methods focused on the installation of bathrooms (plumbing and toilet) that differ from the traditional wet method. This study examined three different sized floor plans at 22 m², 46 m², and a combined one resulting in 69 m². The larger 69 m² plan utilized a removeable non-load bearing wall to increase flexibility in the layout of the floorplan. The apartments are constructed of steel reinforced concrete composite columns on a 9 m × 10.5 m grid with integrated slabs. The exterior and interior infill walls are all non-load bearing with some containing plumbing. This separation of the structure and infill walls can help meet some of the criteria in the long-lastig housing certification, particularly with the ease of repairs. Technologies that facilitate the replacement of infill elements that contain plumbing and other building services can benefit the nation by reducing carbon emissions and therefore tax incentives should be introduced to increase the adoption of the proposed construction methods.

In this paper, we propose a new caching scheme for continuous media data where the buffer allocation unit is divided into two modes : interval and object. All of objects' access patterns are monitored and based on the results of monitoring, a request for an object is decided to cache its data with either interval mode or object mode. The results of our simulation show that our proposed caching scheme is better than the existing caching algorithms such as interval caching where the access patterns of the objects are changed with time.

Upon changing architectural education system into 5-year program, the design studio in university should meet the requirement in order to acquire the accredition. This study investigates on student' perceptions and responses, according to the configuration(open, mixed, closed), to their studio environment. Results and suggestions are as follows for all types: First, there should be space for individual activities for the student: Second, excluding space for excluding space for the individual work, seperated area must be provided for co-operative work, such as making models; Third, a clear territorial distintion between the individual and the co-work space should be able to set by the students, using. for instance, movable partition or corridor; Fourth, however, in line with the types, a seperated lecture or seminar room in the open type, a device to prevent distraction such as noise in the mixed type, and more space for co-work in the closed type are also suggested.

Today, the rapid economic growth and emerging new trends have been changed radically throughout the society and they especially have affected the changes of life-style and the diversity of residents'demands in housing life. This changes of life have brought the shift in family form from traditional type, thus new phase of nuclear family means that it makes on the whole, variable family forms such as single family, non-blood one, a generation one and so on. It therefore is time that we should not only explore current housing plans, but envisage concept of new living space to satisfy latent need of the occupants. But the forms, in spite of the diversity of user's needs and the change of life-style, of many houses as many apartment and tenement houses supplied so far have been clearly limted, and housing policy of the mass-supply causes monotonous space composition, over-occupation and non-changeability. Now, the collective houses have some limits owing to the commoness and assemblage, but they have failed to keep up with the variable and changeable life-style of residents. These problems, to put it concretely, lead to increasing needs for the number of rooms in proportion to family members, for the change of behavior using the space. We therefore need to propose the new living space. As the current plans for designing house are based on the average life-style of people, they can not cope with variable demands of the resident. For that reason, this paper will propose the manual space system as an alternative for it and the goal is to suggest new furniture system which we need to create the flexibility of living space.

The receiver operating characteristic (ROC) curve was developed to quantify the classification ability of marker values (covariates) on the response variable and has been extended to survival data with diverse missing data structure. When survival data is understood as binary data (status of being alive or dead) at each time point, the ROC curve expressed at every time point results in time-dependent ROC curve and time-dependent area under curve (AUC). In particular, a follow-up study brings the change of cohort and incomplete data structures such as censoring and competing risk. In this paper, we review time-dependent ROC estimators under several contexts and perform simulation to check the performance of each estimators. We analyzed a dementia dataset to compare the prognostic power of markers.
