Citrus tristeza virus (CTV) is the causal agent of one of the most important diseases of citrus. Recently, CTV has been detected in Cheju Island by ELISA. The coat protein (CP) gene of CTV isolated form Cheju Island was cloned by RT-PCR and the nucleotide was analyzed in this study. Citrus leaves were collected from trees showing decline symptoms from various region of Cheju Island in the summer of 1998 and 1999. The CP gene open reading frame is composed of 670 nucleotides and encodes a polypeptide of 223 amono acids. Sequence analysis the CP gene revealed that two CTV strains present in Cheju Island. Viruses collected form Sogwipo area and Cheju City area in 1999 ahowed 91-93% nucleotide sequence homology with CTV T36 strain. Viruses collected form Cheju City area in 1999 and Sogwipo City in 1998 showed 94-98% nucleotide sequence homology with CTV SY568 strain. A efficient viral RNA extraction methods was developed by modifying procedure for animal virus RNA purification methods and PCR product was detected form one tenth of RNA purified from as small as 45 mg fresh or frozen tissue.

This study investigates the impacts of urban land-use fraction and temperature advection on the urban heat island intensity over the Seoul metropolitan area using the UM (Unified Model) with the MORUSES (Met Office Reading Urban Surface Exchange Scheme) during the heat wave over the region from 2 to 8, August 2016. Two simulations are performed with two different land-use type, the urban (urban simulation) and the urban surfaces replaced with grass (rural simulation), in order to calculate the urban heat island intensity defined as the 1.5-m temperature difference between the urban and the rural simulations. The land-use type for the urban simulation is obtained from Korea Ministry of Environment (2007) land-use data after it is converted into the types used in the UM. It is found that the urban heat island intensity over high urban-fraction regions in the metropolitan area is as large as 1℃ in daytime and 3.2℃ in nighttime, i.e., the effects of urban heat island is much larger for night than day. It is also found that the magnitude of urban heat island intensity increases linearly with urban land-use fraction. Spatially, the estimated the urban heat island intensities are systematically larger in the downwind regions of the metropolitan area than in the upwind area due to the effects of temperature advection. Results of this study indicate that urban surface fraction in the city area and temperature advection play a key role in determining the spatial distribution and magnitude of urban heat island intensity.

The importance of church school education is becoming more emphasized. To maximize the effectiveness and efficiency of church school education, frequent utilization of instructional media is more desirable. Systematic approach to media utilization will be developed by the extabilishment of church media center. The purpose of this study was to review the concept and components of church media center and to survey the current status and hope for the facility of church media center. For the survey the 400 questionnaries were distributed to pastors or missionaries who are responssible for education, or personnels in church media center in Korea. The churches that they belong to have above approximately 500 church members. Among the distributed questionnaires, the 202 were collected. The results of the survey are as follows. The printed media and the AV media were managed separately in most churches. Many church media center was shared the space with other programs. The space was allocated mainly for storage. Most respondants hoped that they have a variety of areas in their churches. Many church media center have no separation between the area for the adults and that for children. However, most respondants hoped the separation of that areas. Followings are suggestions for the plan of church media center facilities. The space only for the church media center should be allocated. Church media center should be located in the first floor of the building as soon as possible. (If there is elevators in the building, it may be located above first floor). If enough space for the church media center is allocated, the areas for the adults and children should be separated by partitions or separate room. The space should consist of various areas like circulation area, reading area, working area for the personnel, production area, and storing area.

Number of children cared by child care centers has getting up almost half of the from zero to five year age group in korea. Home care children' activities are reported more active and natural than those of center care children. So this study seek the design guidelines for the residential core model of child care centers as second home in korea. The residential core model by Anita Lui Olds was selected and ten domestic center cases were surveyed for guidelines. Firstly, daily-residential core model is learning by daily life at home, and is equiped with cooking kitchenet and group activity area in group room. Secondly, play-residental core model is learning by playing by self, and is equiped with acting, eating and reading common area clustering two or three group room. Thirdly, eco-residental core model is learning by eco-friendly activities, and is equiped with companying, cooperating and sharing area. Fourthly, project-residental core model is learning by project by self, and is equiped with drawing, experimenting and presenting common area. Fifthly, the space of residential core model is organized with three or four group room and clustering living or common area. The larger the center is, the more the cluster is vertically. Facility area and outdoor playground per child is about 7 and $3m^2$.

In the 1980's opening 79 of the end of 2013, the National Public Library that had been It was 885 its opening remains in effect. Especially in the 2000s after 60% of the whole library, a library erected since the advent of the library is enough to be a significant quantitative expansion. The resulting to make a qualitative aspect of public libraries and increase users' needs for efficient space configuration. IIn particular, the user is to serve the needs of digital reading room and the increase of the cultural training changes after 2000 years ago, and appears as due to the implications of space configuration in an age-appropriate library space off the rate plan is a necessary point. The study in the 1980s-1990s, built public library established since the year 2000 centered on public library mutual comparative analysis of space configuration form. Book reading function was the conservation and highlight 1980-1990s and considered by the side of the users culture area extended since the 2000s, public library takes the difference between the ratio of the area of the facility by the area in which you can meet the standards required and the age.

This study analyzed the trends and current status in public libraries in Korea for 14 years, focusing on the overview and facilities of public libraries using public library statistics from 2007 to 2020. The research data were collected from the National Library Statistics System and compared with the population and GDP per capita of Korea. As a result, the number of public libraries in Korea is 1,172 as of 2020, which has nearly doubled compared to 2007, and it was found that this increase has a very strong correlation with GDP per capita and population. There were 229 contracting out public libraries operating by the local government in 2020, and the contracting out rate increased from 18.8% in 2007 to 25.1%. Although the site area of public libraries varies greatly from library to library, it tends to get larger over time. The total floor area of public libraries operating by the Office of Education is larger than that of public libraries operating by the local government, and it gradually increases over time, but the total floor area of public libraries operating by the local government have decreased slightly. The total number of seats in the library is decreasing in all libraries, and the reading seats for children and the reading seats for the elderly and the disabled tend to slightly increase.

In order to solve the current shortage of parking spaces, and redesign the main gate area of the U University, the research investigated some cases of other schools located in Seoul which actively constructed multi-purpose building structures. Those schools are considered to be good samples showing their efforts to fulfill the needs of more parking spaces in their campuses, and to cover with the growing needs of multi-functioned facilities accommodating services of academic affairs, reading room spaces, and amenities. With the investigation, the research finded out the current trends of campus developments from the sample schools, such as underground parking facilities connected with multi-purpose buildings along the main arteries of campuses. Following the trends the research thoroughly examined the present conditions of our school and tried to make some possible alternatives for the facilities. Under the conditions, the research suggested 1)to construct underground parking lots accepting around 1,000 cars under the ivory tower square located in front of University Administration Building, 2)to develop a big-scaled open square at the university main gate, and 3)to build a multi-purpose structure along the main street of the campus, which included administration services, studying spaces, and some commercial facilities.

The study aimed at investigating the living time as well as disability degree of the elderly based on daily living acting capability and living activity degree. The survey was conducted through the home-visit interview during half month at july, 1996 by the students of nursing department who were previously trained. The survey targeted the elderly aged 65 years or more living at home in rural area. The study tried to utilize Activity Inventory(AI) made for examing health and disease, disability degree, and living acting degree of the elderly. Among the AI's, there are Physical Activity of Daily Living(PADL), Instrumental Activity of Daily Living(IADL), maximum daily activity scope, and physical and mental activity level of the elderly. The daily living time is surveyed physiologic time(sleeping, eating and grooming), labor time(occupation, housekeeping and farming) and leisure time(reading, sport hobby-life). Results of the study show that social activity degree of the elderly is found to be lower than that PADL, LADL, and daily living scope. It seems that the elderly suffer from inability in daily life with lower social activity degree. But the labour time of the daily living time is the most amount time in the targeted 361 elderlys through random sampling. Therefore postponement of the disability of aging should be devised to encourage the labour activity of the elderly.
