Because of a recent trend of the open and globalized world economy, international trade is getting bigger and there is a trade competition among many countries, resulting in competition between harbor industries. Therefore, as hub-port development of China, Japan and Taiwan is more actively progressing than any other times, Korea should prepare a powerful management system to take the initiative over them. Above all, a new recognition of the governmental officers in charge of political management about hub-port industry and early development of the northeast hub-port are needed. To maximize its distinctiveness from competitive ports, port sale should be actively managed. As well, as port functions are diverse, accompanied site development should be prepared. In conclusion, in order to improve functions of a port and develop the port as a general complex of physical distribution, the government should encourage the accompanied site development and support preparation of a customs-free area and a general system of physical distribution.

The increasing prevalence of inactivity and obesity, along with aging, has implications on work capacity of labor force. This study reports the relationships between activity level and BMI by age with objectively measured physical workload. Data were examined from a sample of 19 481 Finnish employees using an estimate of minute-to-minute oxygen consumption based on R-R interval recordings. The mean estimated %VO₂max during the working day was 12.1 (±3.6) and 15.1 (±4.5)% for men and women, respectively. Based on a linear model, the mean %VO₂max increased by 1.5%-unit per 10-year increase in age, by 2.1%-unit per 5 kg/㎡ increase in BMI, and decreased by 1.6%-unit if improving physical activity class by two (p < 0.001 for all). Overweight and obesity, together with inactivity, notably increases workload throughout the career, even though at young adulthood, the daily workload is almost the same for each person regardless of the BMI, activity level, or gender. This study highlights the importance of regular physical activity and normal weight in protecting the worker from excessive physical (cardiovascular) workload during the whole working career.

This paper considers the effect of "comprehensive rural community improvement project" in terms of three factors - physical environment, rural tourism, socioeconomic and analyzed the path effect leading to the final outcome - the quality of life of residents, using covariance structure analysis. By doing so, this study looks into why residents prefer the improvement of a physical environment that takes a public nature. The analysis showed that the socioeconomic effect did not have an immediate impact on the improvement of quality of life of residents at a significance level of 5%, whereas the improvement of physical environment had a static effect on the quality of living at a significance level of 1%. Residents' preference for "hardware" or physical environment may be attributed to lack of their understanding of human factors such as social capital. However, analyzing the impact of specific contents of the project on performance, it is found that as projects fail to generate a tangible socioeconomic effect, residents strategically prefer the repair of their physical environment such as public facilities that directly affect their daily lives, so that they can maximize an improvement of the quality of living. Hence, this study suggests that instead of attributing the failure of rural community development projects to residents, macroscopic problems of rural communities and specific contents of projects should be dealt with before the success of any project can be discussed.

The purposes of this study were to demonstrate whether a Physical Rhythm Education Program can alter children's rhythm perception and rhythm expression. To solve the questions posed by this study, 60 5-year-olds and 60 6-year-olds (a total of 120 children) from one child-care center in Kyunggi-province were selected. An experimental group participated in the Physical Rhythm Program which was carried out 10 times over the course of 4 weeks. The results indicated that the Physical Rhythm Program positively improved the children's rhythm perception and rhythm expression. In particular, the Physical Rhythm Program was more effective in producing effects upon six-year-olds' rhythm perception and rhythm expression (verbal, instrumental and physical expression) than five-year-olds' rhythm expression (instrumental and physical expression).

This study analyzed physical knowledge displayed in the utterances of 10 Korean children 23 - 76 months of age. Utterances were blocked into four-month time periods, except the first two months and classified into 5 categories including properties of physical objects and materials, friction, buoyancy, gravity, and the motion of physical objects. All five types of physical expressions were found in the data of the earliest period the percent age of the properties and motion was higher than the percent of friction, buoyancy, and gravity. Data suggested two transitional points of change in physical knowledge : 2-year-old's descriptions were based only on perceptually salient physical features 3- to 4-year-olds described only end-state results while children older than 4 included systematic causality.
