  • The purpose of this study is to provide basic data for the establishment of the management plan of Seoullo 7017 after analyzing the characteristics of immigration plants in addition to those introduced plants. The taxa number of plants appeared as 276 taxa including 82 families, 161 genera, 246 species, 1 subspecies, 22 varieties and 7 forms. Among them, immigration plants appeared 79 classification groups, including 32 families, 65 genera, 77 species and 2 varieties. Invasive alien plants appeared as 22 classification groups in 79 classification groups of immigration plants. The ratio of America origin plants, second period(1932~1960) in introduction time and the wide diffusion species is high. In June, the growth and occurrence time of the immigration plants was the highest by monthly the characteristics of the growth of the immigration plants, the immigration plants appeared mostly. In case of dormancy form among life-form, the therophytes(th), in the propagation form-radicoid form, the R5(monophyte), in the propagation form-disseminule form, the gravity D4(having no special modification for dissemination), and in the growth form, the erect form(e) was high. The various immigration plants appeared in green areas covered by Zoysia japonica and low Hedera helix densities. This study is the first flora study since Seoullo 7017 was opened in 2017. And so continuous flora monitoring is required for Seoullo 7017.

  • 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.

  • The purpose of this study was to analyse the structure and contents of clothing construction field in the middle-school textbook of technology and home economics with curriculum revised in 2007. 10 kinds of textbooks certified by Ministry of Education, Science and Technology in 2010 were selected and home economics field in them was the subject of this study with the external characteristics such as textbook system, instruction area and contents included. This study was content analysis-oriented and descriptive with data calculated by frequency and percentage. The findings are as follows. In 'Reality of Home-Life', food life area showed highest as 34.4% followed by clothing life(28.7%) and dwelling life(28.7%). The portion of present teachers in writing staffs was highest while there was no textbook where professors of each field were included in writing staffs. The contents of costume society, clothes material, clothes management from section 'Choice and Management of Clothes' in the chapter 'Family Life' and clothing construction from the section 'Making and Modifying Clothes' of the chapter 'Reality of Home-Life' were analysed in this study. Clothing construction-related fields were suggested separately by method of measurement, construction theory, drafting theory, drafting an original form, fabric trimming, utilization of the original form, length measure, cloth cutting, hand stitching, how to use a sewing machine, basting and correction, needlework process, completion, and evaluation. The contents of the unit 'Making Shorts' were about clothing construction theory, human body measurement, drafting an original form, process of making shorts and activity/research/experience. The contents of the unit 'Wearing Clothes after Fixing' in clothing construction-related field were about how to fix and recycling.

  • The morphological optimization of Trichoderma harzianum was carried out using several surfactants to achieve increased cellulase production. Addition of the surfactants to the culture medium successfully modified the fungal morphology from an aggregated form to a dispersed form. Optimization of the fungal morphology increased cellulase activity up to 177%. The morphologically optimized conditions enhanced the accessibility of the fungus to substrates and thus promoted cellulase production.

  • Through a field study of the folk houses, 'Closed ㄱㄴ Type' in Goyang-si, Gyonggj-do, focused on the dweller's life by the method of ethnographic interview, observation, and physical survey. L and opposite L type of inner and outer buildings form a closed inner court, and innermost backyard for woman is enclosed by fence. Form and space of the house contains dweller's traditional life. Outer space of a front gate becomes semiprivate space, for thrashing and piling up harvest and raising vegetables and pigs. Confucius principle does not fully dominate dweller's life of ancestral rite at Daecheong floor, and separation of man's and woman's quarter. Superstitious worship activities took place for lord of site and house. In everyday life, Anbang, inner main room, is assigned for parent's quarter instead of woman's quarter, and Geornbang, next room, was for son's family. Anbang has symbolic meaning for a place of deathbed. House contains agricultural activities, crop harvesting, thrashing, putting into storage, hulling rice, and keeping grain near kitchen. At present, rooms are needed more; sheds are made into rooms, rooms are enlarged toward outside, half outside space like Daechong floor becomes interior space by sash screen. And modern facilities of kitchen and bathroom are equipped for convenience. At the end, meaning and generative principle of those forms are discovered.

  • Purpose: This study examined the effects of individual reminiscence therapy on older adults' depression, morale, and the quality of life. Methods: The design was a single-group pre-test and post-test study. Subjects consisted of 31 older adults from two senior centers and a welfare center in Seoul. Individual reminiscence therapy was applied to study subjects four times, once a week for an hour at each time. Measurement tools were the Geriatric Depression Scale Short Form Korea (GDSSF-K) for depression, Mun Ae-ri's (1996) scale for morale, and Medical Outcomes Study Short Form 36 (SF-36) for the quality of life. Data was analyzed using descriptive statistics, paired t-test, and pearson correlation. Results: The application of individual reminiscence therapy reduced older adults' depression (t=-5.65, p=.000), and enhanced older adults' morale (t=4.65, p=.000). The application of individual reminiscence therapy improved older adults' quality of life (t=5.00, p=.000). Conclusion: Findings of the study suggest that individual reminiscence therapy may be applied as a nursing intervention that contributesto the improvement of older adults' quality of life, reduces their depression, and enhances their morale.
