This experiment was carried out to obtain basic information on the lodging characteristics and yield components of rice plants by new anti-lodging reagent 'KIM-112' (3%, Wp) application at 30 days before heading (DBH) to 5 DBH under two dosage levels (lg 2g, a. i. /10a) at the Yeongnam Crop Experiment Station in 1989. Culm length was shortened by 10-17% at 1g, a. i. /10a and by 16-23% at 2g of KIM -112 applications. The shortening effect of internode was different by dosages and application times: 2g treatment was greater effect than 19 and early application resulted in shortening of lower internode while this was upper internode at the late application. There were positive correlation between culm length and lodging index, the 1st and the 4th internode lengths had on important effect to lodging index. Thickness of culm wall, culm diameter and weight of basal part of culm were not affected by KIM-112 application. However anti-lodging characters improved by increasing the breaking weight and by decreasing the moment. Lodging index was related to breaking weight, moment and weight of panicle. Heading date by KIM-112 application was delayed one to four days and number of grains per panicle was decreased by shortened panicle length as compared with untreated control, but yield capacity was high a little because of improvement ripening ratio by no lodging.

Lodging in the direct seeded rice cultivation on flooded paddy is being severe problem due to the lower production and grain quality at ripening stage. This study was conducted to examine the effect of Iprobenfos-metconazole (IPM) treated 50, 40 and 30 days before heading respectively as a plant regulator to reduce the lodging at ripening stage of direct seeding rice cultivation. The culm length treated with IPM, especially the 4th culm internode, was shortened more than with untreated plot, and the most effective time was at 30 days before heading. At 20 days after heading the flag leaves colour showed more greening than in the untreated leaves and the plot with IPM treatment was to be maintained longer compared to the control plot. The Nitrogen concentration of leaves with IPM was lower than in the control plot, and $SiO_2$ contents were higher than in the untreated plot and $SiO_2/N$ ratio was increased more in the IPM plot than in the control plot. The breaking strength of 3rd and 4th culm internode with IPM treatment was higher than in the untreated plot, and the lodging index was reduced in the IPM plot significantly and the field lodging also was reduced. As the results the rice production in the IPM plot was increased more due to be higher ripening ratio and seed grain weight compared to the untreated plot to be occurred the field lodging.

An experiment was carried out to know the effects of paclobutrazol application time on the lodging related traits and yield of a rice variety. Seomjinbyeo, at two nitrogen leveles. Paclobutrazol (3kg 10a of 0.6% G) was applied 43, 33, 23, and 13 days before heading (DBH) and lodging related traits were observed 10, 20, 30, and 40 days after heading (DAH). Earlier applications of paclobutrazol reduced the length of lower internodes and later applications reduced the upper internodes. Culm length tended to decrease as time of paclobutrazol application delayed. Although lodging was not occurred in all plots. lodging index of paclobutrazol treated plots was lower than that of control and increased with maturity, Fresh weight of shoot increased up to 30 DAH and then decreased. Both fresh weight and breaking strength did not show consistent tendency with time of paclobutrazol application and observation. Direct effect of shoot fresh weight contributing to lodging index decreased with maturity. but that of breaking strength and culm length was similar during the ripening stages. Direct effect contributing to lodging index was greater in the order of breaking strength culm length. and fresh weight 40 DAH. Starch content of culm base decreased up to 20 DAH and then increased up to 40 DAH. Cellulose content increased up to 20 DAH, but hemicellulose and lignin did not change significantly during the ripening stages. Starch, cellulose, hemicellulose, and lignin contents of culm base did not correlated with breaking strength and time of paclobutrazol application did not show consistent results. Paclobutrazol applied 13 DBH did not reduce yield of rice. but the earlier applications reduced yield due to a reduced number of spikelets per panicle.

The objective of this experiment was to find out the effect of agro-chemicals on the lodging in paddy field. Sioz added into soil up to 130 ppm and K$_2$O applied 15kg/10a at land preparation. 2.4-D sprayed 250g/10a on the 30 days after transplanting and kitatchin G. applied 3kg/10a on the 30 days before heading. The most efficient agro-chemical to prevent lodging was kitatchin which applied 3kg/10a on the 30 days before heading. Generally, kitatchin and 2.4-D were reduced plant height and lodging index, but decreased grain yield.

As one of the conservation strategies, the city of Jeonju established regulations to conserve and revitalize the Hanok village as an attractive tour site. Some of old traditional houses were renovated into traditional inns. A couple of traditional houses were additionally built for lodging houses. The need for urban rehabilitation and adaptive re-use has been growing in Jeonju province. The purpose of this study was to examine how the traditional houses were converted into lodging places balancing the conflict issues such as preserving the unique characteristics of Hanok and updating functional requirement of modern lodging in terms of sustainable reuse and development. For this study, site visits and intensive interview with the owners of the seven traditional lodges were conducted. There was lack of guidelines and strategies renovation or rehabilitation of Hanok as lodging facility for sustainable use and revitalization of city. For the seven traditional Hanok inns, layout of rooms characterized as separate and disconnected, while traditional houses were open, flexible and connected regarding room arrangement. In addition, for sustainable development, the living environment of the community should be secured and align with developing strategies of the area.

Two different cultivars of barley, with either the ordinary-level or double-strength nitrogen application, were grown in two districts simultaneously, in order to study the extent of dwarfing in plant height, lodging and grain-yield increase with ethylene-releasing agents (Ethrel and dl-methionine alone or in combination). The shorter the plant height, the less the extent of lodging and the grain yield there were. With 500ppm Ethrel, 10% grain-yield increase was attained without showing apparent lodging, irrespective of the level of nitrogen applied. The double-strength nitrogen application resulted in severe lodging more than the ordinary-level and control, and lower grain yield accordingly. Consideration for importance of barley lodging in Korea today and the controlling measure with ethylene treatment for dwarfing, and yield increase by increased nitrogen application, were discussed.

To establish the method of direct seeding cultivation in rice (Oryza sativa L.), direct surface seeding with treatments of N application rate, application of growth regulator(PP333), and seeding rate were conducted from May to Oct., 1989 at the experimental field of Sunchon National University. There were no significant differences among treatment means of N application rates, and seeding rates, which seemed to be due to severe occurrence of field lodging. Application of PP333 reduced culm length by 3-4m, but it did not affect the occurrence of lodging. The optimal seeding rate to maximize the number of spikelets per unit area was estimated to be 6kg seed /10a. To obtain stable yield in cultivation of direct surface seeded rice in submerged paddy field, it was necessary to reduce occurrence of field lodging through breeding of lodging resistance genotypes rather than cultural practices.

The Youth Hostel in Korea, differently from that of other countries, has been introduced in order to attract School Excursion Group, and was developed as one of Youth Training Facilities. Youth Hostel as Youth Training Facility can be utilized as a healthy experiential space for youth education, as a stage for an international interchange, as a field for the lifelong education of various classes, and is also the Lodging Accommodation which is now highly appearing of the demand as a safe and educational lodging place to both individuals and family-unit tourists. The Purpose of this Research is aimed to provide the necessary fundamental materials to the planned forthcoming future Youth Hostel, after grasping of such present status as well as its structure and composition of space and spacial characteristic. Since Youth Hostel in Korea is managing on the center of the basis for youths and other groups, in order to compute the proper heads, it is required the scale-level which can accommodate all students in One-Unit Grade of a school at minimum. Accordingly, it seems that must be equipped with accommodating capacity of more than 300~400 persons. As because of recent quality-improvement in the portion of Youth Hostel Lodging, it is under planning with containing of the Sanitary Space at inside of lodging room, and Self-Cooking Space as well. In compliance with such various particulars, it looks that the lodging area should be at least more than $3.5m^2$ per a person.
