After applying anti-smoking acupuncture to 756 high school students at least 4 times, I surveyed about the effect of the therapy. The result of the survey is as follows. 1. The age to start smoking is getting lower. And the rate of female students' smoking is increasing significantly. 2. The survey shows that students started to smoke mainly because of curiosity, stress, peer pressure, and their misunderstanding which the way to smoke looks cool. 3. The anti-smoking acupuncture therapy is expected to decrease the smoking desire because the applicants usually experience headache, dizziness, gastroenteric trouble after the treatment. 4. Students complained about earache and inconvenience of washing. 5. The result shows that the anti-smoking acupuncture therapy is generally efficacious, but the virtue of the therapy is much better with the students' willingness to stop smoking.

To study on the actual condition of care label attached to clothing and consumers' perception, 250 summer clothes sold at department store-blouse, trousers, one-piece dress, knit cardigan and skirt-were investigated during July 2000. In addition, a questionnaire was administered to 192 women in Taegu during August. The fiber contents of surveyed clothes were polyester 100% & polyester blend (26%), rayon 100% & rayon blend (18%), cotton 100% & cotton blend (17%), wool 100% & wool blend (14%) and others. All clothes surveyed were attached care label and the signals showed on care labels were 4~6 kinds about cleaning, squeezing, drying, bleaching, and ironing methods. 92% of clothes had to be dry-cleaned and only 8% could be wet-cleaned. Considered the surveyed clothes were for summer which needs frequent washing and the clothing items, the number of clothes had to dry-cleaned were too many. The bleaching instructions were no chlorine bleach (74%), no bleaching (21%) and others. The ironing instructions were cool ironing ($80{\sim}120^{\circ}C$) with cover (24%) and warm ironing ($140{\sim}160^{\circ}C$) with cover (69%) primarily. The drying instructions was dry on a hanger in the shade (54%) and 38% had no signal or incorrect signal. The properties of summer clothes considered important by consumers were wrinkled hardly, hand-washable, machine-washable, needed no iron and etc. Actually most of summer clothes were hand or machine-washed. Also, the majority of respondents felt inconvenient to have to dry-clean summer clothes. More than 80% respondents looked over care label and fiber content label before buying clothes. However most of respondents did not followed that instructions exactly and thought care label instructions were not correct. Considered this results, the suppliers have to make efforts to attach correct and appropriate care label which furnish the correct information to consumers.

In this study, I investigated the applicability of fluorescein-derived xanthene dyes to fluorescent pigment and the controllability of the optical properties of manufactured pigments. Eosin Y (D&C Red No.22) and phloxine B (D&C Red No.28) were mainly used as a dye to prepare the pigment. Dyes dissolved in a solvent were poured into a powder dispersed in the solvent, then dried and pulverized to fabricate the pigments. Optical characteristics related with fluorescence of the prepared pigment were measured. The optical properties of pigments were varied depending on the solvent used, content of the dye in the pigment, and the ratio of dyes when more then two dyes were mixed. According to the experiment result, it seems that some of the dyes attached to the powder showed fluorescence while the rest did not contribute to it. From the result of pigment washing experiment to explore the binding (or interaction) strength and characteristics of the powder-dye system constituting the pigment, it seems that there are two or more different interactions existing in the pigment system, one of which is relatively stronger than the solvent-dye interaction.

Purpose: The aim of this study was to compare the tumor-free and overall survival rates between patients with low-risk endometrial cancer who underwent surgical staging and those who did not undergo surgical staging. Materials and Methods: Data, including demographic characteristics, grade of the tumor, myometrial invasion, cervical involvement, peritoneal washing, lymph node involvement, lymphovascular space invasion, postoperative complication, adjuvant treatment, cancer recurrence, and tumor-free and overall survival rates, for patients with low-risk endometrioid endometrial cancer who were treated surgically with and without pelvic and paraaortic lymph node dissection (LND) were analyzed retrospectively. The patients diagnosed with endometrioid endometrial cancer including the following criteria were considered low-risk: 1) a grade 1 (G1) or grade 2 (G2) endometrioid histology; 2) myometrial invasion of <50% upon magnetic resonance imaging (MRI); 3) no stromal glandular or stromal invasion upon MRI; and 4) no evidence of intra-abdominal metastasis. Then the patients at low-risk were divided into two groups; group 1 (n=117): patients treated surgically with pelvic and paraaortic LND and group 2 (n=170): patients treated surgically without pelvic and paraaortic LND. Results: There was no statistical significance when the groups were compared in terms of lymphovascular space invasion, cervical involvement, positive cytology, and recurrence, whereas the administration of an adjuvant therapy was higher in group 2 (p<0.005). The number of patients with positive pelvic nodes and the number of metastatic pelvic nodes were significantly higher in the group with positive LVI than in the group without LVI (p<0.005). No statistically significant differences were detected between the groups in terms of tumor-free survival (p=0.981) and overall survival (p=0.166). Conclusions: Total hysterectomy with bilateral salpingo-oophorectomy and stage-adapted postoperative adjuvant therapy without pelvic and/or paraaortic lymphadenectomy may be safe and efficient treatments for low-risk endometrial cancer.

Objectives: This study was conducted to investigate derived factors associated with a public service announcement on handwashing to evaluate the effect of this announcement. Methods: In early september, 1,000 persons over 19 years old was investigated by Computer Aided Telephone Interview, at last 993 persons for analysis. Outcomes were the exposure to the public service announcements on handwashing, the comprehension of this announcements, the intention of behavioral change and the practice of handwashing. Results: In particular, the proportion of exposure is more women and highly educated. The comprehension of the announcement was no statistically significant difference. The intention of behavior change showed higher in workers and understanding of the announcements. The practice of handwashing is higher in women and lower in student/unemployed. There was no difference in practice in accordance with the exposure, the comprehension and the intention of behavioral change. Conclusions: About the comprehension of the announcements and the intention of behavioral change, the effects of the public service announcements on handwashing can be very positive. But it does not affect the actual practice of hand washing. The handwashing promotion programs will have to devise a strategy and structure, operation method considering realistic and scalable platform.

The Geumran-gasa (Kasaya) and Jangsam of the monk Samyeong are historical relics and were designated as object No.29, a Buddhist costume of the Joseon Dynasty, by the National Folklore Cultural Heritage, in 1973. In 1984, after being treated for the purposes of washing and preserving the shape of the garments, the object was kept in the Temple Museum of Pyochungsa, as their holding institution. However, regular inspection conducted by the Cultural Heritage Administration in 2013 determined the need for a re-treatment. The Geumran-gasa had been originally made with 25 strips, but it had been separated into two parts and many pieces were lost. A part of the collar in the Jangsam was lost as well. Therefore, both relics needed to be restored. The re-treatment process involved pre-investigation, washing, reinforcement fabric dyeing, restoration, and fumigation. In particular, we focused on reinforcing the damaged parts and restoring the missing parts by applying advanced materials and methods in order to restore the original form as much as possible. This conservation is the result of the re-treatment of the cultural properties by replacing the old material used in past treatments and applying advanced methods under the basic principle of reversibility in conservation treatment.

Background: The development of the flexible fiberoptic broncoscope by Ikeda was an important technologic advance in the diagnosis and management of patients with pulmonary disease. But, cross contamination related to fiberoptic bronchoscope was reported in cases involving tubercle bacilli, MOTT and other agents. Therefore, cleaning and disinfecting of fiberoptic bronchoscope requires careful attention. Methods: From September 1991 to May 1992, medical records of all patients with positive culture for MOTT in bronchial washing specimens were reviewed. Also to evaluate bactericidal effect of 2% glutaraldehyde, culture was performed after inoculum of MOTT, Serratia marsescens and Pseudomonas aeruginosa to the disinfectant solution. Results: In 2% alkaline glutaraldehyde, MOTT was not survived only after 30 minute exposure, but P. aeruginosa and S. marsescens were rapidly inactivated with no survivors after exposure to 2% glutaraldehyde. Since vigorous mechanical cleansing and more than 30 minute of contact time within washing machine, no more outbreak was observed. Conclusions: It is also very important that bronchoscopes must be meticulously cleaned after each procedure and more than 30 minute exposure would be required for eradication of MOTT with 2% glutaraldehyde. However even the most strictly applied infection control measures cannot exclude contamination completly and clinicians have to stay alert to this possibility. Prompt detection of pseudoepidemics is possible if abrupt increase in isolation rates, especially if they involve unusual or generally nonpathogenic organisms, are readily recognized.

For the study of method for promoting the germination of Korean sod seeds harvseted newly some physical and chemical treatments were tested in this experiment. The summarized results of these tests are as follows: 1. Storage of wet seed in low temperature of 0~$2^{\circ}C$ during 2~30 days was seemed the most effective treatment for promoting the germination of sod seed. 2. The treatment that Soaking and mixing up the seeds in cone sulphuric acid about one and half minutes and then washing off in the water promoted fairly the germination of sod seeds. 3. Better germination of sod seeds was found in the light than in the dark or soil. 4. Cutting the top of seed and crushing of seed coat with sand seemed to promote slightly the germination of sod seeds. 5. No promoting effect for germination of sod seeds was found with treatments of Gibberellin, $NH_4$ $NO_3$ and NAA.

In this study, ultrasonic spray pyrolysis combined with salt-assisted decomposition, a process that adds sodium nitrate ($NaNO_3$) into a titanium precursor solution, is used to synthesize nanosized titanium dioxide ($TiO_2$) particles. The added $NaNO_3$ prevents the agglomeration of the primary nanoparticles in the pyrolysis process. The nanoparticles are obtained after a washing process, removing $NaNO_3$ and NaF from the secondary particles, which consist of the salts and $TiO_2$ nanoparticles. The effects of pyrolysis temperature on the size, crystallographic characteristics, and bandgap energy of the synthesized nanoparticles are systematically investigated. The synthesized $TiO_2$ nanoparticles have a size of approximately 2-10 nm a bandgap energy of 3.1-3.25 eV, depending on the synthetic temperature. These differences in properties affect the photocatalytic activities of the synthesized $TiO_2$ nanoparticles.

Background: Bronchofiberscopy is a procedure with a chance of airway irritation and it may cause pathophysiologic changes of respiratory system. So we tried to evaluate the influence of bronchofibercopy on $O_2$ saturation, ABGA and PIT by patient's basal status and procedure type. Method: $O_2$ saturation was measured every 1 minute from the left index finger tip with percutaneous oximetry. ABGA was done before and right after the bronchofiberscopy and PIT was done before and within 10 minutes after the bronchofiberscopy. Results: The mean time for bronchofiberscopy procedure was 14.5mim and $SaO_2$ maximally fall to 89.0 below 8% of the baseline after mean time of 8.4min, which was recovered at the end of the procedure. $SaO_2$ change amount was 8.4 % on Non-$O_2$ supply group, which was lower compared to 6.4 % of the $O_2$-supply group without statistically significance. Biopsy Group and BAL group showed more $SaO_2$ fall than washing only group. The level of $PaO_2$ and FEV1 of the patient didn't influence significantly on $SaO_2$ fall during the procedure. ABGA taken before and after the bronchofiberscopy showed mild fall of $PaO_2$ and mild rise of $PaCO_2$. Whereas PFT showed decrease of FEV1(P<0.05) and increase of RV without changes in airway resistance and pulmonary diffusion capacity. Comparing before and after the bronchofiberscopy, the washing group showed no significant changes on PIT, while the biopsy group and the BAL group showed increase of RV & decrease of $FEV_1$ after the bronchofiberscopy. BAL group showed more changing tendency rather than biopsy group although not statistically significant. Conclusion: Bronchofiberscopy is considered as a relatively safe procedure, but it would be better to be done with $O_2$ supply especially in the patient with low $PaO_2$ and in the case of biopsy and BAL.
