The "leading farms" or "superior management farms" were relatively capable to overcome various limitations in rapidly changing agricultural environment and economic conditions, and quick to adopt agricultural management innovations and accomplish more compared to the other farms in shorter durations. The farmers from these "leading farms" were innovative and dynamic, and endowed with potentials to be the core leaders in rural society. Their adaptability created a difference and worthy of emulations. The purpose of this research was to propose a policy to develop, promote and sustain these leading farms. There were some problems in communication structures and in implementing agricultural policies for upbringing leading farmers. In coordination with the Ministry of Agriculture and Forestry(MAF) and Rural Development Administration (RDA), this article attempted to come up with workable strategies to solve these problems affecting the leading farms.

D&B method in tunnel construction requires accurate and rapid measurement of the ground movement, which of essential for feedback analysis. Recently, survey technique adapting IT is getting more and more emphasized in the field of construction and tunnel survey also follow the same trend. Case study and adaptability of IT technique for tunnel survey will be discussed in this study. The application of laserscannig method in the field of tunnel construction was reported in several advanced country including Austria and Japan. Survey for the crown and shoulder movements by IT survey method was conducted and the results were compared to those do the conventional method. The pipe-roof, grouting, ring-cut are installed in the this site to prevent expected large ground settlement. The result show that laserscanner system is prefered rather than conventional method in that better understanding for the displacement condition and origin condition was liable by the lasersacnnig method. IT survey solution makes if possible to execute more economic and safe construction.

Objectives : The purpose of this study was to examine the factors related to children's health behavior. Methods : A self-administered questionnaire survey was carried out for 431 (boys; 227, girls; 204) children, 6th grade students, in Taegu from December 14 to 18 in 1998. This study employed health promotion model as a hypothetical model. Collected data were analysed through the chi-square test, ANOVA, and path analysis. Results : By univariate analysis, in case of boys, health practice was related to perceived self efficacy, perceived health status, perceived benefits of health-promoting behaviors, and perceived barriers, and in girls, health practice was related to perceived self efficacy, perceived benefits of health-promoting behaviors, perceived barriers, and cues to action. By path analysis, in case of boys, the better economic status, the younger mothers' age, the higher score of family cohesion and adaptability, healthier, the more perceived benefits, and the less perceived barriers were, the more health behaviors were practiced. Girls did the more health practice, in case of living with parents only, the higher score of family cohesion and adaptability, the more perceived self-efficacy, the less perceived barriers, and the more cues to action. Family cohesion had the most important effect on health practice of primary school students. Conclusions : In order to promote health behavior of primary school students, a good family environment as well as health education might be very important. That is, we have to try together in home and as well as in school.

The purpose of this study was to compare the temperamental differences between the normal infants and low-birth-weight infants. The subjects of this study were 70 mothers with normal infants and 62 mothers with the low-birth-weight. Convenient sampling was done at three regions. The infant temperament scale developed by Pridham & others (1994) was used. Data were analyzed by SPSS WIN program. The results were as follows; 1) There was a significant difference in total temperament score between the low-birth-weight infants and normal infants. The scores of the low-birth-weight infants were significantly lower than those of normal infants in the subscales of amenability and persistence, activity, and reactivity. In adaptability, there was no significant difference between two groups. 2) In both groups, there were no significant difference by socio-economic status of parents, delivery type, and birth order. But, in the case of low-birth-weight infants, the temperament score of infants over 6 months was significantly higher than that of infants under 6 months. 3) In the correlation analysis among subscales of the temperament, amenability and persistence, activity, and reactivity showed the significant relationship. But adaptability showed significant correlation only with the amenability and persistence. In conclusion, temperament score of low-birth-weight infants were significantly lower than that of normal infants. It was suggested that parenting education for low-birth-weight infants would be needed to understand and impact the positive infant temperament.

D&B(Drill & Blast) method in tunnel construction requires accurate and rapid measurement of the ground movement, which is essential for feedback analysis. Case study and adaptability of IT technique for tunnel survey are discussed in this paper. The application of laserscannig and existing light wave instrument method in the field of tunnel construction were reported in several advanced country including Austria and Japan. Survey for the shoulder movements by IT survey method was conducted at a subway construction site and the results were compared to the conventional method. Also, the economic aspects of laserscannig method were analyzed using measured data which were categorized by expenses, frequency, interval and period in the field of construction. Therefore IT survey solution may contribute to execute more economic and safe construction

This review has been done to examine sex-linked dwarf gene in broiler production in hot-humid climates. Introduction of sex-linked dwarf gene especially in hot harsh tropical environments brings a great advantage for broiler production. The heavy broiler parent suffers due to the stress of these adverse climates. Sex-linked dwarf genes reduce body weight, egg weight, but are superior for adaptability under harsh tropical environments, with a lower requirement for housing and feed, better survivability and reproductive fitness giving fewer defective eggs, more hatching eggs, better fertility, hatchability, feed conversion efficiency and resistance to disease. Overall the cost of chick production from dwarf hens is lower than from their normal siblings. Market weights of broilers from sexlinked dwarf dams is almost similar to those of broilers from normal dams with normal sires. But the net benefit of broiler production from sex-linked dwarf dams is found to be greater than that of broilers from normal dams. This will be the most important to the rural communities in Bangladesh and in other countries where the similar environment and socio-economic conditions exist. Therefore, sexlinked dwarf hens might be used in broiler breeding plan as well as broiler production in the tropics.

Availability of reliable and affordable energy supply is a prerequisite for economic growth. Renewables are the third largest contributor to global electricity production after coal and natural gas and account for a share of 18%. Power generating capacity from renewables has increased to around 900GW by the year 2007. Today biodiesel fuels have been in commercial use in many countries and recently the world-wide biodiesel market has experienced considerable growth, which is partly due to various tax concession programs and other financial incentives. In Korea, biodiesel has already been used for transportation fuel, but not used for power generation fuel yet. Korean government has a strategy for renewable energy propagation, especially the goal of power generation amount by renewable energy is 3% of total power production by 2012. This paper focuses on the feasibility study for adaptability and strategy of using biodiesel as power generation fuel. The study also has the plan to replace the fuel of thermal power plant, gas turbine and distributed power system. As the increase of biodiesel fuel, I look forward to environment-friendly power generation and the strategy of Renewable Portfolio Standards(RPS).

The volume of parcel delivery is steadily increasing with the rapid growth of the global online e-commerce market. However, a large amount of packaging materials used for these parcel delivery is finally causing environmental problems as waste. In this study, we have taken a pilot test on the returnable parcel delivery packaging & service, which is one of various ways to reduce the generation of the distribution packaging waste raised by e-commerce-based parcel delivery. For the purpose of this project, we made 300 boxes of returnable & foldable delivery packaging(415 mm × 280 mm × 160 mm) and have cooperated with e-commerce company(CJ ENM) & logistics company(LogisAll). Consequently, about 50% of the delivered packages was returned because of the lack of consumer's understanding on the returnable packaging system. We finally have suggested the policy strategy to get over problems derived from the experiment, like the retrieval rate and cost of the returnable packaging, economic efficiency and so on.
