This study examines the effect of present and future situation on the temporal distance estimation to the future. The effect of present and future situation on time expression was verified. In Experiment 1, an experiment was conducted to investigated the effects of positivity/negativity situation of the present and the future on the judgment of subjective the distance to a certain future time. The results are as follows. When the present is positive and the future is negative, the future looks closer than the objective temporal distance and comes faster, When the present is negative and the future is positive, the future looks farther and comes slower. On the other hand, when the present and the future are both negative, the future looks coming slower. And when the present and the future are both positive, the future is expected to come faster. In Experiment 2, the cognitive and emotional aspects of subjective time through time expressions. It can be said to be 'the time of perseverance' in the sense of time for effort. On the other hand, when the present is positive compared to the future, the time seems go fast and we generally prefer to use cognitive expressions such as 'fast' and emotional expressions such as 'near' and 'pleasant' and 'flutter'. It is 'the time of availability', which means the time to enjoy and utilize.

This study was conducted to investigate the awareness tendency of the government employees who manage forest roads about problems of forest road use and how to improve them in the future using surveys. The results show there are more silvicultural operations than harvesting operations using forest roads. The main purpose of using forest roads is to transport workers; however, the road will be used more for harvesting operations in the future. The respondents wanted to be accessibility for forest operations within 200 m from road in both present and future. For silvicultural operations 1-ton vehicle is used at present, and 5-ton vehicles are expected to be used in the future. For harvesting operations 5-ton vehicle is used at present, and 10-ton vehicles are will be used in the future. The roadway width is 3 - 4 m at present, but should be 4 - 4.5 m in the future. The longitudinal gradient of roads is 7 - 10% at present, and will be below 10% in the future. The minimum curve radius of roads is 12 - 15 m at present, and will be 15 - 20 m in the future. The results provide basic data for making future forest road policies.

This study was to analyze the job of cooks of school foodservice. The purpose of this study were to examine importance of the present job and future-oriented job of cooks in school foodservice, and to compare the present job performance time with the future-oriented job performance time. The questionnaire was delveloped by focus group and pilot test. The work sampling was choosed to verify the objectivity of job analysis. The statistical software package was SAS 10.0. ‘Menu Management’, ‘Procurement’, ‘Receiving and Inventory control’ and ‘Cooking facilities Management’ of the present job was perceived significantly more important than the future-oriented job. ‘Procurement’, ‘Receiving and inventory control’, ‘distribution’ and ‘dishwashing’ of the future-oriented job was perceived significantly longer than the present job performance time. This study will be used to develop job specification for the cooks of school foodservice.

The purpose of this study was to figure out the urban establishing families' economic structures(income, expenditure, assets, first-present-future housing cost etc.), the states of first-present housing, the future housing plans, and the housing preferences. For this purpose 274 establishing families in Seoul and its metro-politan area were interviewed through the standardized questionnares. Finally 264 questionnares were analyzed. The major findings were as follows; 1. The important source of their monthly incomes was the labor income. But there was often the transfer income from their parents. And the important items of monthly expenditures were savings and foods. In higher income classes, the traffic cost was important relatively. 2. It was found that the urban establishing families were very dependent on their parents for their first-present housing costs. The dependency was stronger in high education classes compared to the low. This was the case in future housing costs. 3. The states and changes of first-present housing showed the demands for an apartment, homeowership, and privacy. These tendencies were higher in high education classes compared to low education classes, but the demands for future housing were according to the monthly income. The present locations were determined majorly by the distance from office and parents. 4. Their housing preferences were different from the present housing states. Furnished rental housing, open living space, large common spaces, and common using of unusual appliances etc. were more preferred by high education classes compared to low education classes.

Commercial machine translation systems have been announcing recently, However, there are problems that the systems have shown mistranslations, yet. Among these mistranslations, this paper is interested in the mistakes of tense processing. The paper compares Korean tenses with 12 English ones: present. past, future, present perfect. past perfect, future perfect. present progressive, past progressive, future progressive, present perfect progressive, past perfect progressive. future perfect progressive. Next, we perform the meaning analysis of Korean tenses. Then we describe the structure of the tenses based on Conceptual Graph(CG). In the experiment. the paper implements the program that translates sentences included in the tenses into CG.

This study was designed to examine leisure time and leisure activities of homemakers and to predict future leisure time and future leisure time orientation. Present leisure time and future leisure time orientation were studied in relation to sociodemographic and physical environmental variables, time use variables and attitude variables. The major findings were the average daily housework time of homemakers was 6.5 hours on weekends. Housework time of employed homemakers was 3.5 hours and full-time homemakers was 8.0 hours. Daily leisure time of homemakers was 4.0 hours on weekdays and 4.8 hours o weekends. Most homemakers leisure activities on weekdays and weekends were reading, watching TV or listening to the radio and resting. In the future, they want to go hiking, hunting, traveling or fishing, attending concerts, drama or movies and playing sports games. The homemakers who felt their amount of present leisure time was sufficient were 35.4% and insufficient were 37.9%. Regarding the present leisure activities, 43.1% of homemakers expressed dissatisfaction, though 21.9% of them satisfied. Factors affecting the homemakers weekday leisure time were homemakers' occupation, family type, type of heating form house and cooking, weekday and weekend housework time of homemakers. Weekend leisure time interacted with family life cycle, number of children, income, education and occupation of homemakers, size of house, type of heating for house and cooking, weekday housework time of homemakers. housework time of employed housekeeper, husbands' weekend housework time, weekday leisure time of homemakers.

Jeju Island is the highest rain-prone area in Korea that possesses affluent water resources, but future climate changes are predicted to further increase vulnerabilities as resultant of increasing of extreme events and creating spatial-temporal imbalance in water resources. Therefore, this study aimed to provide basic information to establish a proper water resources management plan by evaluating the effects of climate change on water resources using climate change scenario. Direct runoff ratio for 15 years (2000~2014) was analyzed to be 11~32% (average of 23%), and average direct runoff ratio for the next 86 years (2015~2100) was found as 28%, showing an increase of about 22% compared to the present average direct runoff ratio (23%). To assess the effects of climate change on long-term runoff, monthly runoff variation of future Gangjeong watershed was analyzed by dividing three time periods as follows: Present (2000~2030), Future 1 (2031~2070) and Future 2 (2071~2100). The estimated results showed that average monthly runoff increases in the future and the highest runoff is shown by Future 2. Extreme values has been expected to occur more frequently in the future as compared to the present.

It is said that first year of e-Paper was 2004, when "sigma-Book" (LCD) by Panasonic and e-Book "Librie" (EPD) by Sony were introduced in the market. After that, many prototypes of e-Paper have followed in 2005. And also the related technologies have been evolved. I summarize the present status of e-Paper technologies and then propose the future trend.
