This study examines whether and how ages of child affect accessibility experiences of women and men differently. Space-time accessibility measures based on Time-geographic framework with activity-travel diary datasets in Portland Metro, US were calculated using GIS-based geocomputation, and spatial-temporal patterns of accessibility of dual-earner couples by ages of their youngest child were compared. The results are as follows. (1) Although more women than men work part-time, which would render women more spatial-temporal autonomy, accessibility levels of women are not higher than men's. It implies that there exists another constraint placed on women which largely stems from gender inequality. (2) It is distinctively women with child under age 6 of which accessibility spaces are found to be restricted doser to home compared to men. Women with no child or with child aged over 6, however, show more or less similar spatial-temporal patterns of accessibility with men's which are quite unvarying regardless of parental status and their child age. Women's accessibility experiences characterized by spatial-temporal entrapment, thus, can be seen as problems associated with gender rather than sex. (3) Intensified spatial-temporal entrapment of women with young child are associated with the significant spatial pegs shaping their accessibility spaces, which are located much closer to home compared to men's: workplaces and child's daycare centers.

Objectives: Time-activity studies have become an integral part of comprehensive exposure assessment and personal exposure modeling. The aims of this study were to estimate exposure levels to nitrogen dioxide($NO_2$) and volatile organic compounds(VOCs), and to compare estimated exposures by using time-activity patterns and indoor air concentrations. Methods: The major microenvironments for office workers were selected using the Time-Use Survey conducted by the National Statistical Office in Korea in 2009. A total of 9,194 and 6,130 workers were recruited for weekdays and weekends, respectively, from the Time-Use Survey. It appears that workers were spending about 50% of their time in the house and about 30% of their time in other indoor areas during the weekdays. In addition, we analyzed the time-activity patterns of 20 office workers and indoor air concentrations in Daegu using a questionnaire and time-activity diary. Estimated exposures were compared with measured concentrations using the time-weighted average analysis of air pollutants. Conclusions: According to the time-activity pattern for the office workers, time spent in the residence indoors during the summer and winter have been shown as $11.12{\pm}2.20$ hours and $12.48{\pm}1.77$ hours, respectively, which indicates higher hours in the winter. Time spent in the office in the summer has been shown to be 1.5 hours higher than in the winter. The target pollutants demonstrate a positive correlation ($R^2=0.076{\sim}0.553$)in the personal exposure results derived from direct measurement and estimated personal exposure concentrations by applying the time activity pattern, as well as measured concentration of the partial environment to the TWA model. However, these correlations were not statistically significant. This may be explained by the difference being caused by other indoor environments, such as a bar, cafe, or diner.

It is happening a lot that the pediatric patients who are offering help in emergency room with background 119 rescuer require emergency care compared to adults. Our study was conducted to have a clear grasp of the status quo of pediatric patients who are offering help in emergency room with 119 rescuer. METHOD & OBJECT pediatric patients under 8 age who were offering help was conducted as objects by 119 cases from January, 2006 to January 2007, with 119 rescuer at C university hospital in Gwangju metropolitan city, which were 87 cases for a boy(73.1%), 32 cases for a girl. Based on emergency diary of emergency members and the medical treatment record of emergency room in C university hospital, a disease and a type of an external wound were analyzed according to ages of these patients, a time zone and season. RESULT In terms of an age, 25 cases(21.0%) have less than 1 age extremelymuch, in case of emergency, 61 cases(51.3%), which were more than non-emergency, in terms of happened places of patients, there were households up to 78 cases(65.5%) extremely much. In terms of happened time, 13:00 to 18:00 have highest data up to 48 cases(40.3%). According to season, there were no big differences in 4 seasons(spring : 30.3%, summer : 24.4%, fall : 29.4%, winter : 16.0%). In case of being offered help at emergency room due to diseases, 1-2 ages have highest estimate with 55.7%, in terms of a time zone, 19:00-24:00 have highest with 33.7%, in terms of season, summer(6, 7, 8) have highest with 32.8%. in case of traffic accident, 7-8 age have highest with 47.1%, according to a time zone, 13:00 to 18:00 have highest with 88.2%, according to season, fall have highest with 64.7%. In case of an external wound, 3-4 age have highest with 38.2%, according to a time zone, 13:00-18:00 have highest with 41.2%, according to season, spring have highest with 38.2%. CONCLUSION It shows that in case of pediatric patients who were offering help at emergency room with 119 rescuer, a pediatric under 1 age was due to a disease, in case of an external wound, there were 3-4 age, in case of traffic accident, 7-8 age have highest, a case for emergency have highest.

This research analyzes the media which is simultaneously used with TV viewing, the behaviour of multiple media users, and the characteristics of TV programs under Nscreen circumstances. According to the results, TV provides stories and positions it as the main screen (84.5%, n=566), under the Nscreen circumstances. Personal media reproduces stories from TV by utilizing aspects of social media functions such as participation, open communication, community, connectivity, etc. The content is classified under three categories: 1) elicit emotion(point feeling), 2) information production, 3) participation, which is further divided into three subcategories; watch, wish, and result guarantee based on the level of interactivity. This inquiry is based upon diary survey and focus group interviews emphasized the role change of TV, specifically that TV takes a key role in generating original stories with the expansion of screen and social media. Even though users were able to watch the same TV programs at the same time and same place, the different methods of viewing: smartphone, tablet PC, web based mp3 and etc., it reproduced different stories and elicited different characteristics from its TV viewers.

Recently, the web service environment has changed from document-centered to data-oriented focus, and the Linked Open Data (LOD) exists at the core of the new environment. Specific procedures and methods were examined to build the LOD of records information in accordance with this trend. With the service sustainability of small-scale archive in consideration, an exemplification on LOD building process by utilizing open source software was developed in this paper. To this end, a 5-step service framework for LOD construction was proposed and applied to a collection of diary records from 'Human and Memory Archive'. Proof of Concept (POC) utilizing open source softwares, Protege and Apache Jena Fuseki, was conducted according to the proposed 5 step framework. After establishing the LOD of record information by utilizing the open source software, the connection with external LOD through interlinking and SPARQL search has been successfully performed. In addition, archives' considerations for LOD construction, including improvement on the quality of content information, the role of the archivist, were suggested based on the understanding obtained through the LOD construction process of records information.

The conventional four-step travel demand model is still widely used as the state-of-practice in most transportation planning agencies even though it does not provide reliable estimates of travel demand. In order to improve the accuracy of travel demand estimation, implementing an alternative approach would be critical as much as acquiring reliable socioeconomic and travel data. Recently, the role of travel demand model is diverse to satisfy the needs of microscopic analysis regarding various policies of travel demand management and traffic operations. In this context, the activity-based approach for travel demand estimation is introduced and a case study of developing a spatial-temporal activity presence-based approach that estimates travel demand through forecasting number of people present at certain place and time is accomplished. Results show that the spatial-temporal activity presence-based approach provides reliable estimates of both number of people present and trips actually people made. It is expected that the proposed approach will provide better estimates and be used in not only long-term transport plans but short-term transport impact studies with respect to various transport policies. Finally, in order to introduce the spatial-temporal activity presence-based approach, the data such as activity-based travel diary and land use based on geographic information system are essential.

Exp. I, the study was conducted to examine the supplementation levels of cassava hay (CH) in dairy cows. Six multiparous Holstein-Friesian crossbreds were paired and randomly assigned in a change-over design to receive three levels of CH supplement at 0, 0.8 and 1.7 kg DM/hd/d. Concentrate was supplemented at the same level (1:2; concentrate:milk yield) while urea-treated (5%) rice straw was offered on ad libitum basis. The results revealed that supplementation of CH could significantly reduce concentrate use resulting in similar milk yield (12.5, 12.12 and 12.6 kg/hd/d) and significantly enhanced 3.5% FCM (14.21, 15.70, 14.9 kg/d, respectively). Moreover, CH supplementation significantly increased milk fat and milk protein percentages especially at 1.70 kg/hd/d. Concentrate use could be significantly reduced by 27% at 1.7 kg/hd/d CH supplementation. Exp. II, supplementation of cassava hay to replace concentrate use was studied in lactating-Holstein Friesian crossbreds grazed on Ruzi grass. Six multiparous cows in mid-lactating periods were paired and randomly assiged according to a change-over-design to receive three dietary treatments, $T_1=0kg$ cassava hay (CH) in 1:2 concentrate supplementation (CS) to milk yield (MY), $T_2=1.0kg$ DM CH/hd/d in 1:3 CS to MY, $T_3=1.7kg$ DM CH/hd/d in 1:4 CS to MY, respectively. The results were found that milk yield were similar among treatments while protein, lactose and solids-not-fat percentages were highest (p<0.05) in cows receiving CH at 1.0 kgjhd/d. Most significant improvement from CH supplementation was the ability to reduce concentrate use by 42% which could provide a higher income for small-holder dairy farmers. In addition, milk thiocyanate was enhanced from 5.3 to 17.8 ppm (p<0.05) in the control and in the CH supplemented group (1.7 kg/hd/d), respectively. Moreover, CH supplementation could significantly reduce concentrate level for diary feeding thus resulted in more economical return. Cassava hay demonstrated as a potential and high-quality on-farm feed resource especially for dry season feeding in the tropics.

This study evaluated the efficacy of topical eprinomectin (0.5% pour-on solution, $Eprinex^{(R)}$, Merial) against Chorioptes texanus (C texanus) infestation in dairy cows reared in Korea. Dairy cows naturally infected with C texanus showed skin lesions as alopecia, erythema, excoriations and crusts on the tail head, the caudal folds, the back of udder and the rump area. Fourteen adult Holstein dairy cows with chorioptic mange at National Institute of Animal Science were selected on the basis of gross lesion and microscopic examination. Experimental dairy cows infected with chorioptic mange were treated with eprinomectin ($Eprinex^{(R)}$, Merial, France) at the rate of 1 ml /10 kg/BW. Evaluation of therapeutic effect is based on mite counts and gross lesion at weekly interval for 6 weeks. Milk yields were measured every day and calculate at the mean of milk yield at weekly interval. Mange mites absolutely removed after 1 week of topical eprinomectin against C. texanus infestation on dairy cows. The skin lesion of dairy cows infested with C. texanus recovered normal status after 6 weeks of eprinomectin treatment. After eprinomectin treatment, return to the normal level of milk yields in diary cows infested with C. texanus has indirectly indicated that C. texanus infestation have negative effect on productivity of dairy farm. However, it would be suggested that the investigation of actual condition and the effective control method of C. texanus infestation of dairy farms in Korea should be studied in the future.

In this paper, the aspects of recollection discourse during the Japanese Invasion of Korea in 1592 are discussed. As a research method the dialectic of oblivion is used. The results of the study are like these: first, the hero discourse of Lee Soon-Sin was the center of the discourse of the Japanese invasion of Korea in 1592 until the 20th century. In the two books Jingbirok and A War Diary written at that time, the subjective and objective description of the war was essential. However, it has a limit that it can't describe the real situation of the war that the people and the soldiers went through, as it focuses on Lee Soon-Sin's inner thoughts. Second, in the 21st century The Song of Sword written by Kim Hoon deals with the inner mind of Lee Soon-Sin in monologue unlike the usual hero discourse. Although as we can see in the records about the marine righteous army, people centered discourse description of the war shows a different way of discourse about the Imjin War. The movie, Myeongryang directed by Kim Han-Min tries to modify the way of remembering the war and presents the real heroes were the people and Lee Soon-Sin was a additional character in the war by showing a lot of battle scenes in the sea. The truth of history can't be found by only researching the recorded materials. As cultural texts dealing with the way of remembering the war, the novel shows a struggling individual not a hero and the movie focuses on that people's active participation led the victory of the war.
