This study is concerned with the functions of dwelling space effected by the tendency that the number of furniture in the household has increased in recent years. The functions of dwelling space were grasped on the basis of dwelling - behavior tenitories. The possession of furniture was surveyed In 144 units of apartment house. Observation with questionnaire was carried out through pilot and main survey. 1) The dwelling - behavior territories of Anbang, Living Room and D.K. each were classified into 4 kinds. These territories were assorted into two categories ; first, the similar territories were integrated and specific various territories formatted, second, new kind dwelling spaces were required2) Accordingly, Anbang have to be re - setted up Anbang and storage, Living Room and D.K. re - setted up L.D.K. and Utility. In this way, it coudld be possible, that creative reasonable space were formated for more satisfactory. Therefore relationships between furniture possession and the usage of dwelling spaces wre identified.

The purpose of this study is analyzing 'observation and recommendation letter by teacher', which is being submitted to screen and enhance the utilization of gifted students in accordance with recently introduced gifted students observation, recommendation and screening system. For the purpose, this study will provide with objective securing plan of 'observation and recommendation letter by teacher' by developing an optimum evaluation model. The research findings were as follows: First, the result of analysis on the mathematically gifted students behavior characteristic as appeared in 'observation and recommendation letter by teacher' suggested that the recommending teachers have the tendency of giving superficial statement instead of giving concrete case description. When it was analyzed for frequency by the 'observation and recommendation letter by teacher' analysis framework devised by the author, the teachers showed the tendency of concentrating on specific questions. Meanwhile, there was a tendency that teachers concentrate on specific gifted behavior characteristic or area for which concrete case had been suggested. The reason is believed that such part is easy to observe and state while others are not, or, teachers did not judge the other part as the characteristic of gifted students. Second, the gifted students behavior characteristics as appeared in 'observation and recommendation letter by teacher' were made into scores by Rubric model. When the interrater reliability was analyzed based on these scores, the correlation coefficient of 1st scoring was .641. After a discussion session was taken and 2nd scoring was done 3 weeks later, the correlation coefficient of 2nd scoring increased to .732. The reason is believed that; i) the severity among scorers was adjusted by the discussion session after the 1st scoring, ii) the scorers established detail judgment standard on various situations which can appear because of the descriptive nature, and, (iii) they found a consensus on scoring for a new situation appeared. It implies that thorough understanding and application of scorers on evaluation model is as important as the development of optimum model for the differentiation of mathematically gifted elementary students.

This study was to examine the characteristics of aggressive behaviour of dementia patients. It was based on the observation of the patients in a facility for dementia patients. Observation continued for two days from 9a.m. to 5p.m .. aggressive behavior was recorded using the instrument of Ryden. The result of this study is as follows. 1. appearance rate of aggressive behaviour During two days $74\%$ of the patients did aggressive behaviour(first day-$41.8\%$. second day-$62.8\%$). The average aggressive behaviour per person was 1.65. 2. types of aggressive behaviour Aggressive behaviour was the most frequent in verbal domain(157 case; $52.5\%$). Physical domain was the second$(136case;\;45.5\%)$, and sexual domain was the last$(6 case;\;2.0\%)$. More concretely, abusive/vulgar language$(74case;\;24.7\%)$ was more than anything else. Aggressive language$(65case;\;21.7\%)$, pushing$(39case;\;13.0\%)$, intimidating posture$(21case;\;7.0\%)$. slapping $(18case;\; 6.0\%)$ followed it. 3. correlation to other factors such as sex. age etc. The average aggressive behaviour of female(2.07) was higher than that of male(1.23) (p=.05). Age also had meaningful correlation to the frequency of aggressive behaviour(p=.04). All the other factors-the period of living in facility, the seriousness of dementia. movements in daily life. CAPE, emotional state. the extent of trouble in cognition- have nothing to do with the frequency of aggressive behaviour. 4. the time, place and the target of aggressive behavior Aggressive behaviour appeared more frequently in the afternoon $(138case;\;46.4\%)$ than in the morning or at lunch time. The patient's room ranked the first in the list of places where aggressive behaviour took place $(162case;\; 54.5\%)$. Nursing personnel topped in the target of aggressive behaviour$(119case;\; 39.8\%)$. 5. the preceding causes of the aggressive behavior the most frequent preceding causes of the behavior was the stimulus of another residents $(133case, 44.4\%)$ and that of nsg personnel was few relatively$(65 cases,\; 21.7\%)$. 6. Nursing personnel used verbal reaction most frequently$(40 cases,\; 51\%)$ and in a behavioral reaction they used physical restraint $(12 cases,\; 17.1\%)$ most frequently. In the reactions of nsg personnel. the rate of undesired reaction was high$(41cases,\; 44.28\%)$. and in that of the attacked residents, the usual reaction was most frequent $(80cases,\; 65.0\%)$. In the future it is needed to investigate the characteristics of aggressive behavior of dementia patients, and based on this the method of intervention must be developed. Today the number of dementia patient increases so nurses must strive to encounter aggressive behavior more desirably.

Many tower-supported steel stacks have been constructed in Japan, primarily for economic reasons. However the dynamic behavior of these stacks under a strong wind is not well known and the wind load design standard for this type of a stack has not yet been formulated. In light of this situation, we carried out wind response observation of an operating tower-supported steel stack with and without a tuned-mass damper. The observation revealed the performance of the tuned-mass damper installed on the stack in order to control the wind-induced vibration. Based on the observed data, we performed a wind tunnel test of a specimen of the stack. In this paper we report the results of the wind tunnel test and some comparisons with the results of observation. Our findings are as follows: 1) the tuned-mass damper installed on the specimen in the wind tunnel test worked as well as the one on the observed stack, 2) the amplitude of the vortex-induced vibration of the specimen corresponded approximately to that of the observed stack, and 3) correlation between Scruton number and reduced amplitude, y/d, (y is amplitude, d is diameter) was confirmed by both the wind tunnel test and the observed results.

Purpose: This study was conducted to identify behavioral items for Korean infants under 24months by naturalistic observation. These items will be the basis for developmental scale for Korean infants. Method: Data were collected by observing and interviewing fifty one infants and their mothers during the period from November 15 to December 14, 2003. Raw data in descriptive form were obtained by unstructured naturalistic observation, and were reformed to behavioral items through discussion with professors in pediatric nursing and experienced nurses in child care department. Also, behavioral items were classified into five developmental areas. Result: Total number of behavioral items was two hundreds and thirty eight. 52 items for motor development, 66 items for personal-social, 40 items for hearing and speech, 41 items for eye-hand coordination, and 39 items for performance. Conclusion: This is meaningful that fundamental items for Korean developmental scale for infants were identified by observing behaviors of Korean infants. On the basis of these items, average age will be calculated for passing each item by testing Korean infants. We hope to develop Korean infant developmental scale as a final outcome in the future research.

This study is designed according to the fact that the feces presumed to be from a Prionailurus bengalensis was found in Ulleungdo Island, where Prionailurus bengalensis is not known to inhabit, and that visual observation of the feces may cause errors in species identification. The feces observed in Ulleungdo Island on October 21, 2019 and August 29, 2020, in Gyeongju on December 4, 2020, and in Jecheon on December 7, 2020 was found intactly on grass, not buried in the ground. Although it was difficult to distinguish and identify the feces of Felis catus and Prionailurus bengalensis with visual observation, the feces collected from Ulleungdo Island was closely related to the Felis catus according to the genetic analysis whereas the ones collected from Gyeongju and Jecheon was identified from Prionailurus bengalensis. Therefore through the gene analysis, this study proved that visual observation of feces with similar appearance, specifically the feces found in Ulleungdo Island, Gyeongju, and Jecheon, may cause errors in species identification. It is judged to be necessary to analyze fields signs and genes for the species identification when using the feces of Felis catus and Prionailurus bengalensis.

This research suggests a way of hygienic space planing of the customer space in the university student restaurant of E University in Seoul. For this study. the behavior observation in the restaurant was conducted in order to analyze the sequence of customer behavior related space planing applying HACCP (Hazard Analysis And Critical Control Point). Also the survey was conducted to analyze opinions of customers about hygiene of the space. The results of the analyses of the observation and the survey were similar in terms of hygiene. In conclusion, for hygienic space planing of the customer space in restaurant, the space circulation should be planned according to the hygienic sequence of customer behavior. The spaces in restaurant should be divided into two areas: the clean area and the contaminated area to prevent cross-contamination. The clean area, such as spaces preparing dishes and food including water and table hall where customers eat, should be separated from the contaminated area such as the spaces where waste is handled and where dirty dishes are kept. In order to prevent cross-contamination, hygiene facility to remove contamination should be located before going to the clean area. More specifically, the hygiene facility should be located between a cash counter and a space preparing dishes so that customers can wash their hands before they touch dishes. Space arrangement with feed-back process to check the possible points of cross-contamination and correct space arrangement until the possibility of cross-contamination is removed in the restaurant.

The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by field measurement survey, and non-participatory observation from 9 child care centers in Daejeon. The field measurement survey were conducted from June 20 to July 20, 2004, whereas non-participatory behavior observation were conducted from September 2 to October 10, 2004. The major results showed the following. 1) The characteristics of outdoor play environment in child care centers showed that most of them were too small and did not use the adequate surfacing to play various activities. In many cases, outdoor play settings was made of play equipment setting, play props and manipulative settings, and tree/vegetation. 2) Child's play behavior has been focused on functional play activity and construction play activity. 3) The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction and multi-complex play equipments produced functional play behaviors on children. On the other hand, where various play areas were put together, we could observe relatively diverse play behaviors. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.

The intensity and duration of sexual behavior in Bos indicus was assessed through the continuous observation of sexual receptivity. Two groups of cows were formed: only synchronized (n = 50) and other group further superovulated (n = 20). An intravaginal implant that released progesterone over 9 d was used. After removing the implant, 25 mg of $PGF_{2{\alpha}}$ was administered. In the superovulated group, the administration of 280 mg (Follicle stimulant hormone) FSH-P1 per cow with a decreasing dosage over 4 d was utilized. In both groups, behavioral observations began at the moment of implant removal. Sexual behavior was analyzed using a Kruskal-Wallis test to compare the mean of hours in estrus, effective mountings and number of mounts/hour during estrus. A nonparametric survival analysis was performed using the time in two ways: i) when an event happened it was placed in a 24 h timeframe and, ii) the time of observation in continuous form (96 h) assessing the difference between curves by the log rank test Chi-square. The only significant difference was the number of mounts/h during receptivity (p<0.05). In the superovulated group three periods of sexual activity during the day were identified, with these events being of greater frequency and duration than the synchronized group (p = 0.02); besides, the superovulated group began estrus before the synchronized group (p = 0.0035) when using the total period. In a simulation study, when the number of observations went from two (06:00-18:00) to three periods (06:00, 12:00 and 18:00) cows detected accurately (<6 h after the onset) increased more than 20%. The results show that superovulated cows presented greater intensity and duration of sexual activity in contrast with only synchronized animals.

In the undercooled melt of $Pd_{40}Cu_{30}Ni_{10}P_{20}$ alloy, the solidification behavior including nucleation and growth of crystals at the micrometer level has been observed in-situ by use of a confocal scanning laser microscope combined with an infrared image furnace. The $Pd_{40}Cu_{30}Ni_{10}P_{20}$ alloy specimens were cooled from the liquid state to glass transition temperature. 575 K, at various cooling late under a helium gas flow. According to the cooling rate, the morphologies of the solidification front are changed among various types, irregular jog like front, columnar dendritic front, cellular grain, star like shape jog and fine grain, etc. The velocities of the solid-liquid interface are measured to be $10^{-5}{\sim}10^{-8}$ m/s which are at least two orders higher than the theoretical crystal growth rates. Combining the morphologies observed in terms of cooling rates and their solidification behaviors, we conclude that phase separation takes place in the undercooled molten $Pd_{40}Cu_{30}Ni_{10}P_{20}$ alloy. The continuous cooling transformation (CCT) diagram was constructed from solidification onset time at various linear cooling conditions with different rate. The CCT diagram suggests that the critical cooling rate for glassy solidification is about 1.5 K/s, which is in agreement with the previous calorimetric findings.
