This study aims to propose a way for evaluating thermal environment vulnerability associated with policy to improve thermal environment. For this purpose, a variety of indices concerning thermal vulnerability assessment and adaptation policies for climate change applied to 17 Korean cities were reviewed and examined. Finally, 15 indices associated with policies for improving thermal environment were selected. The selected indices for thermal vulnerability assessment were applied to Daegu Metropolitan City of South Korea as a case study. As results, 15 vulnerability maps based on the standardized indices were established, and a comprehensive map with four grades of thermal vulnerability were established for Daegu Metropolitan City. As results, the area with the highest rated area in the first-grade(most vulnerable to heat) was Dong-gu, followed by Dalseo-gu and Buk-gu, and the highest area ratio of the first-grade regions was Ansim-1-dong in Dong-gu. Based on the standardized indices, the causes of the thermal environment vulnerability of Ansim-1-dong were accounted for the number of basic livelihood security recipients, the number of cardiovascular disease deaths, heat index, and Earth's surface temperature. To improve the thermal environment vulnerability of Ansim-1-dong, active policy implementation is required in expansion and maintenance of heat wave shelters, establishment of database for the population with diseases susceptible to high temperature environments, expansion of shade areas and so on. This study shows the applicability of the vulnerability assessment method linked with the policies and is expected to contribute to the strategic and effective establishment of thermal environment policies in urban master district plans.

Raw-red bean (RR) should be boiled in hot water, and only boiled-red bean (BR) has been used in the food industry. In the course of development of functional food using red- bean (Phaseolus radiatus L), hot- water extracts (HWEs) of RR and BR were prepared, respectively and their components and various biological activities were compared. The extraction yield at $100^{\circ}C$ of RR (16.2%) was higher than that of BR (14.8%), and contents of total polyphenols, total flavonoids and reducing sugars of HWE of RR were 2.5-fold, 2.1-fold and 1.5-fold higher than those of HWE of BR. In anti-oxidation activity assay, scavenging activities against DPPH anion and ABTS cation as well as reducing power of RR was higher than those of BR. The results suggest that the anti-oxidant compounds in red bean might be heat-liable or discarded during boiling in hot-water as a cooking drip. Unexpectedly, nitrite scavenging activity was stronger in HWE of BR than RR. In anti-microbial activity assay, HWE of RR ($500{\mu}g/disc$) showed growth inhibition activity against gram-positive bacteria, whereas HWE of BR did not show any activity against any tested bacteria and fungi. Assay of in-vitro anti-diabetes and anti-thrombosis activities, which were previously reported in ethanol extract of red-bean, revealed that HWEs of RR and BR did not show significant activities against ${\alpha}$-amylase, ${\alpha}$-glucosidase, thrombin, prothrombin, or blood coagulation factors. Our results suggest that the anti-oxidation, anti-diabetes and anti-thrombosis activities of HWEs of RR and BR were lower than those of ethanol extracts of red bean, and bioactive substances in RR were destroyed during boiling or discarded after boiling. Further research on suitable boiling and re-use of cooking drip of red bean is necessary.

In the present study, we investigated the plant growth characteristics and biological activity of four asparagus cultivars grown using two cultural methods and tested the possibility of domestic open field. The number of shoots, buds, roots, shoot and root fresh and dry weights, and total dry weight of the four asparagus cultivars grown in a plastic house were higher than those of the same cultivars grown in an open field. Of the cultivars grown in the open field, Jersey Giant had greater shoot number than the other cultivars. In plastic house cultivation, the number of buds in Jersey Supreme was greater than the other cultivars. The total flavonoid content of the Jersey Giant was greater than the other cultivars, but cultural method was unaffected. The total polyphenol contents in asparagus cultivars grown in the plastic house were higher than those of cultivars grown in the open field. The total polyphenol content of the Jersey Giant grown the plastic house was significantly higher than those of other cultivars. Antioxidant activity such as catalase (CAT) and peroxidase (POX) did not differ significantly with cultural methods and among the cultivars. Ascorbate peroxidase (APX) activity of asparagus cultivars grown in the open field was higher than that of cultivars grown in the greenhouse; the highest APX activity was detected in UC157. Thus, greenhouse cultivation is expected to improve plant growth characteristics and biological activities of asparagus cultivars; each cultural method should be considered when selecting a suitable cultivar for high yield and high bioactive compound content.

The early carcinoma of the uterine cervix may be treated by either radical surgery or radical radiotherapy according to the patient's characteristics, and the survival is high with either treatment. But, because of the size of the lesion, metastasis to lymph nodes, and vascular space invasion by tumor have all been shown to influence recurrence and survival, postoperative radiotherapy may be considered as their histopathologic finding after radical surgery. However, there are still debates on the increasing survival rates with postoperative radiotherapy. Two hundreds and three patients with carcinoma of the uterine cervix who were treated with postoperative radiotherapy from February 1979 to September 1982 in the Department of Therapeutic Radiology, Seoul National University were analyzed and following results were obtained. 3-year actuarial survival rate and 3-year disease free sruvival rate were $83.4\%\;and\;73.4\%$ respectively and 3-year actuarial survival rates by stages were $90.7\%$ for IB, $69.6\%$ for IIA, and $85.2\%$ for IIB. 3-year disease free survival rates by stage IB, IIA, IIB were $79.8\%,\;07.8\%,\;68.3\%$ respectively. The overall failure rate was $25.1\%(51/203)$; local recurrence rate was $8.4\%$, distant metastasis rate was $14.3\%$ and simultaneous local recurrence and distant metastasis was $2.4\%$. Failure rates by stages were $19.8\%$ (18/19) for IB, $29.1\%$ (16/55) for IIA and $29.8\%$ (17/57) for IIB. The overall acute complication rate was $57.6\%$; tolerable cases was $50.2\%$ and severe cases was $7.4\%$.

In an attempt to elucidate the fate of 3,4-DCA and TCAB in various French soils, uniformly $^{14}C-ring-labeled$ 3,4-DCA and TCAB mere utilized and the following results obtained. 1) The rate of breakdown of $^{14}C-3,4-DCA$ into $^{14}CO_2$ was relatively higher in the early stage than that in the later stage. In 6 months of incubation in alkaline soil (pH 7.9), the rate was as high as 6.5% at dose 1 (1.5 ppm) and as low as 1.92% at dose 2(94 ppm), whereas in organic acid soil (pH 5.5) the rate was 4.91% at dose 1 and 4.24% at dose 2, respectively, without making any great difference between the two levels. 2) At dose 1, 47.70% of the initial radioactivity of $^{14}C-3,4-DCA$ was bound to soil in organic acid soil and 29.49% bound in alkaline soil, whereas at dose 2, 38.40% in organic acid soil and 20.30% in alkaline soil, respectively. 3) The amount of formation of $^{14}C-TCAB$ from $^{14}C-3,4-DCA$ seems to depend largely on the concentration of 3,4-DCA applied rather than on soil types. At dose 2, the amount was 50% of the total radioactivity extracted in organic acid soil and 30% in alkaline soil, corresponding to 1.8% and 1.4% of the initial radioactivity applied to soil, respectively. Cis-TCAB also seemed to be formed at dose 2 in both soils. Meanwhile, at dose 1, even though $^{14}C-TCAB$ was detected in trace on tlc and glc in both soils, the amount does not exceed 2 to 3% of the radioactivity extracted, corresponding to 0.05 to 0.1% of the initial radioactivity. 4) The rate of breakdown of $^{14}C-TCAB$ into $^{14}CO_2$ ranged from 0.05 to 0.20% in all the four soils. Most of the applied $^{14}C-TCAB$ remained intact after 3 months, not producing any detectable metabolites. 5) The fact that much more $^{14}C-TCAB$ was adsorbed to alkaline soil than to the other soils strongly indicates that in alkaline condition trans-isomer was converted tocisisomer which has the higher adsorption affinity than the former.

Intraoral filled type of orthodontic appliance can cause reversible or irreversible damages such as gingivitis, periodontitis, enamel decalcification, dental caries, root resorption, and pulpal changes. Such adverse effects are brought by increase in dental plaque as well as oral flora. Such an increase causes gingival inflammation and enamel decalcification. The purpose of this study is to get klowledge on initial changes in dental plaque, gingivitis, and enamel decalcification after bonding fixed orthodontic appliances according to time flow, gender, and sides(right/left) of premolar region. For control group, 48 students of dental college, Yonsei university(26 males, 22 females) were chosen; for experimental group, 73 orthodontic patients(36 males, 37 females) who will be treated with fixed appliances were chosen. All the subjects had no systemic disease, juvenile periodontitis and all the females had passed their ,menarche. Tooth brushing instruction was given to all the subjects prior to the experiment. For control group, plaque index, gingival index, and decalcification index were measured twice at 3 weeks interval ; for experimental group, the same was done prior to, 3, 6, 9 weeks after bonding fixed appliances. The following results were obtained: 1. In plaque index 3 weeks after placement of appliances, and it showed gradual increase afterwards. 2. In gingival index3 weeks after placement of appliances, and afterwards it showed increase at a faster rate than plaque index. 3. Enamel decalcification began to show between 3 and 6 weeks after bonding fixed appliances. Decalcification index began to increase 6 weeks after appliance placement, but there was no statistical significance. 4. When the comparison was made between two sides of premolar region, the right side showed greater index in plaque and gingival index of experimental group.

Purpose: The purpose of this study is to identify and assess the needs of the cancer patients and their families and provide basic data to meet with their needs. Methods: This is a descriptive study using questionnaire method. Questionnaire were collected by mail from 76 discharged patients from a hospice ward from May until the end of October, 2004, and data were analyzed by SPSS 10.0. Results: Admitted patients had needs of pain control (85.5%), non-pain symptoms (63.2%) such as vomiting, dyspnea, ascites, etc, and emotional and spiritual problem solving (28.9%, 14.5%). Interests of patients were health care of himself/herself (65.8%), concern for their spouses left alone (32.9%), and future of their children (15.8%). In families' needs of care of 5 areas, "information on patient's status and treatment/nursing care" was shown most high score ($3.48{\pm}0.62$). In detailed questions, they request most 'to inform the prognosis of patients' and the next is 'to inform the reasons that nursing care was required'. The next highest score was to 'inform family roles' ($3.39{\pm}0.64$), and next was spiritual support ($3.11{\pm}0.79$), and emotional support ($3.08{\pm}0.72$). Expectations of family on the treatment were comfortable dying (73.4%) scored the highest. Patients' families were satisfied with volunteer service most in service area (97.4%). The next was pain control (89.5%) and nursing service (77.6%). Conclusion: Health care staff should identify the actual needs of families caring cancer patients and they should operate realistic programme which can give continuous and assistance by reflecting individual needs and characteristics. With these srategies, the quality of life of patients and families can be improved. And then the intervention programme should be developed to measure subjective nursing care needs of terminally ill cancer patients and their families.

Oxygen consumption has been regarded as a useful indicator for assessment of mammalian embryo quality. This study was performed to investigate whether oxygen consumption reflects morphological grade of in vivo derived bovine blastocyst-stage embryos (blastocyst). The oxygen consumption of in vitro produced blastocyst was compared to its total cell number. In addition, pregnant rate was measured after transplantation of in vivo blastocysts with different oxygen consumption. The quality of blastocyst collected on day 7 after artificial insemination was categorized as grade I and II (G I and G II) based on microscopic observation of the morphology. Oxygen consumption of blastocyst was measured using a scanning electrochemical microscopy (SECM) and total cell number of in vitro blastocyst was enumerated by counting cells stained by propidium iodide. Pregnancy of recipient cow was confirmed with rectal palpation after 60 days of embryo transfer. The oxygen consumptions of G I blastocysts were significantly higher than those of G II blastocysts ($10.2{\times}10^{15}/mol\;s^{-1}$ versus $6.4{\times}10^{15}/mol\;s^{-1}$, p<0.05). Total cell numbers of in vitro blastocysts were 74.8, 90.7, and 110.2 in the oxygen consumption of below 10.0, 10.0~12.0, and over $12.0{\sim}10^{15}/mol\;s^{-1}$ respectively. Total cell number was significantly increased in embryos with high oxygen consumption (p<0.05). Pregnant rate in recipient cow was 0, 50, and 85.7% in the transplantation of embryo with the oxygen consumption of below 10.0, 10.0~12.0, and over $12.0{\times}10^{15}/mol\;s^{-1}$, respectively. These results suggest that measurement of oxygen consumption may help increase the pregnant rate of bovine embryos.
