This research tried identifying the current status of Gyongrodangs to find solutions to the problems of the oldest old through revitalization of the existing senior centers. With 31 national and public Gyungrodangs in Seocho-gu, Seoul as research subjects, the research contents include a survey of the facilities including main exit doors, living rooms and lounges, kitchens, and rest rooms in the Gyungrodangs by the checklist, and as the research tool a laser finder, measuring tapes, and cameras were used. The checklist was used as the research method to investigate main exit doors, living rooms and lounges, kitchens, and rest rooms. Based on the research results, the following conclusions are presented. The safety-related items of the public Gyungrodang facilities were reaching a critical level. They need to equip emergency exit routes, install exit lights and alarm bells, and teach how to use them. After that, the issue of rest room would be raised; the oldest old had difficulty in using the rest room with no consideration of universal design(UD), so installation of grab bars is needed around toilets, washstands, and urinals. Besides them, although absence of the western style furniture without consideration of users' ages caused inconvenience of using, there are no solutions due to the limited space. Unnecessary equipment such as treadmills which only occupy spaces without users should be thrown away and replaced with the furniture people would use like tables with supplement of furnitures to lie down and rest. Overall, the current Gyongrodang Facilities lack systems and need standardized management, in which the checklist this researcher developed and used in evaluating the present conditions could be recommended. It is expected that the evaluation system of senior centers would be arranged through this checklist, so that systematic service supply could be possible in the better facility environment.

The history of the Korean lighthouse have been known to be begun from which installed by the purpose of the Japanese invasion of the outside. Modern navigational aid system have configured during the Japanese ruling era since the Incheon Palmido Lighthouse was built in 1903 as the first lighthouse in Korea. But in this regard it needs to be considered more carefully. Busan, as the city of international port and of Choryang Waegwan, had been a center of foreign relations between Korea and Japan since early 15th century. Because that reason, International port facility has been developed for a long time ago in Busan for example lighthouse, breakwater, wharf, jetty and so on. Nevertheless the lack of historical data and basic research related to the marine caused the proper history could not be established until now. In recently the basic translation of Korean Maritime Customs documents started to finish, and a compilation book of old pictorial maps on Choryang Waegwan was issued. As a result, more objective history of Busan Aids to Navigation can be investigated.

This study purposed to examine the effect of the horticultural therapy on activities of daily living and cognitive function of demented old adults in facilities. According to the results of evaluating BADL, the ability to perform daily activities decreased from 9.71 to 9.21 in the control group, but in the experimental group, the ability to perform daily activities increased significantly(p=.009) from 10.86 before the horticultural therapy to 12.43 after the therapy. According to the results of evaluating K- MMSE, the score decreased from 10.57 to 9.07 in the control group, but the experimental group showed a significant improvement in cognitive functions from 10.43 before the horticultural therapy to 13.29 after the therapy(p=.003). As presented above, the horticultural therapy was effective in improving activities of daily living and cognitive function of demented old adults.

Seedling characteristics of rice sowed at different sowing date in an automatic facility were studied at different days after sowing (DAS). The objective was to determine the optimum sowing date and age of rice seedlings at three locations in the Kyongbuk Province of Korea viz, Andong, Euisung and Kyongsan. Heigbt and shoot dry weight of rice seedlings increased from 10 to 20 DAS and with a delay in sowing time from April to June. In these intervals shoot dry weight-height ratio decreased. For rice seeded in the last ten days of April, optimum seedling characteristics were attained between 15 to 20 DAS at Andong and Euisong and 15 DAS at Kyongsan. At the three locations, 10-day-seedlings exhibited superior characteristics to 15- and 20-day-seedlings for rice seeded in May and June. Rice seedlings of different ages were transplanted at a paddy field to determine the effect of seedling age on yield potential. The mean yield of 10-day-seedlings was 5% higher than that of 35-day-seedlings raised by the conventional method. The yield of 20-day-seedlings was 9% lower than that of 35-day-seedlings. Varietal differences in seedling characteristics of 13 rice cultivars were evaluated for the seedlings seeded in the automatic facility on June. Ten-day old seedlings ranged in height from 13.3 to 17.5 cm and shoot dry weight from 7.7 to 9.4 mg. Two cultivars, Daesanbyeo and Hwayeongbyeo, exhibited superior seedling traits compared to the remaining 11 cultivars and were, therefore, better adapted to the automatic seedling-raising facility.

Purpose: The daily changes of accommodation at period 1 (08:00~10:00), period 2 (13:00~15:00) and period 3 (18:00~20:00) were surveyed with fifty two incipient presbyopia of from 38 to 49 years old. Methods: 52 incipient presbyopia subjects (30 men, 22 women) were classified into 4 groups (groupI: ${\geq}$ 7 hrs~group IV: < 3 hrs) according to near working amount. Their amplitude of accommodation, accommodative facility and relative amplitude of accommodation were inspected, respectively. Results: The amplitude of accommodation was measured to be the lowest for the groupI that near working time was the most during daily work, and the amplitude of accommodation of oculus dexter, oculus sinister and oculus uterque were the highest at period 2 in case of all the group I~IV. In the accommodative facility, it appeared that the oculus dexter, oculus sinister and oculus uterque of group I, oculus dexter and oculus sinister of group II, and oculus dexter, oculus sinister and oculus uterque of group III were the highest at period 2. The oculus uterque of group II and oculus dexter, oculus sinister and oculus uterque of group IV were the highest accommodative facility at period 3. It appeared that the negative relative accommodation was the highest at period 1 in case of all the group I~IV, and the positive relative accommodation was the highest at period 2 in case of the group I~III and was the highest at period 3 in case of the group IV. Conclusions: Because the difference of near working time affects the accommodation, it would become a help in solving the asthenopia symptom of the incipient presbyopia that opticians consider their near working time during daily work and take a checkup on their accommodation.
